Title: simple online and realtime tracking with a deep association metric.

Abstract: Simple Online and Realtime Tracking (SORT) is a pragmatic approach to multiple object tracking with a focus on simple, effective algorithms. In this paper, we integrate appearance information to improve the performance of SORT. Due to this extension we are able to track objects through longer periods of occlusions, effectively reducing the number of identity switches. In spirit of the original framework we place much of the computational complexity into an offline pre-training stage where we learn a deep association metric on a large-scale person re-identification dataset. During online application, we establish measurement-to-track associations using nearest neighbor queries in visual appearance space. Experimental evaluation shows that our extensions reduce the number of identity switches by 45%, achieving overall competitive performance at high frame rates.

A large number of taxonomies are used to rate the quality of an individual study and the strength of a recommendation based on a body of evidence. We have developed a new grading scale that will be used by several family medicine and primary care journals (required or optional), with the goal of allowing readers to learn one taxonomy that will apply to many sources of evidence. Our scale is called the Strength of Recommendation Taxonomy. It addresses the quality, quantity, and consistency of evidence and allows authors to rate individual studies or bodies of evidence. The taxonomy is built around the information mastery framework, which emphasizes the use of patient-oriented outcomes that measure changes in morbidity or mortality. An A-level recommendation is based on consistent and good-quality patient-oriented evidence; a B-level recommendation is based on inconsistent or limited-quality patient-oriented evidence; and a C-level recommendation is based on consensus, usual practice, opinion, disease-oriented evidence, or case series for studies of diagnosis, treatment, prevention, or screening. Levels of evidence from 1 to 3 for individual studies also are defined. We hope that consistent use of this taxonomy will improve the ability of authors and readers to communicate about the translation of research into practice.

Review articles (or overviews) are highly valued by physicians as a way to keep up-to-date with the medical literature. Sometimes, though, these articles are based more on the authors' personal experience, anecdotes, or incomplete surveys of the literature than on a comprehensive collection of the best available evidence. As a result, there is an ongoing effort in the medical publishing field to improve the quality of review articles through the use of more explicit grading of the strength of evidence on which recommendations are based. 1 – 4

Several journals, including American Family Physician and The Journal of Family Practice , have adopted evidence-grading scales that are used in some of the articles published in those journals. Other organizations and publications also have developed evidence-grading scales. The diversity of these scales can be confusing for readers. More than 100 grading scales are in use by various medical publications. 5 A level B recommendation in one journal may not mean the same thing as a level B recommendation in another. Even within journals, different evidence-grading scales sometimes are used in separate articles within the same issue. Journal readers do not have the time, energy, or interest to interpret multiple grading scales, and more complex scales are difficult to integrate into daily practice.

Therefore, the editors of the U.S. family medicine and primary care journals (i.e., American Family Physician, Family Medicine, The Journal of Family Practice, Journal of the American Board of Family Practice , and BMJ-USA ) and the Family Practice Inquiries Network (FPIN) came together to develop a unified taxonomy for the strength of recommendations based on a body of evidence. The new taxonomy should: (1) be uniform in most family medicine journals and electronic databases; (2) allow authors to evaluate the strength of recommendation of a body of evidence; (3) allow authors to rate the level of evidence for an individual study; (4) be comprehensive and allow authors to evaluate studies of screening, diagnosis, therapy, prevention, and prognosis; (5) be easy to use and not too time-consuming for authors, reviewers, and editors who may be content experts but not experts in critical appraisal or clinical epidemiology; and (6) be straightforward enough that primary care physicians can readily integrate the recommendations into daily practice.

Definitions

A number of relevant terms must be defined for clarification.

Disease-Oriented Outcomes

These outcomes include intermediate, histopathologic, physiologic, or surrogate results (e.g., blood sugar, blood pressure, flow rate, coronary plaque thickness) that may or may not reflect improvement in patient outcomes.

Patient-Oriented Outcomes

These are outcomes that matter to patients and help them live longer or better lives, including reduced morbidity, reduced mortality, symptom improvement, improved quality of life, or lower cost.

Level of Evidence

The validity of an individual study is based on an assessment of its study design. According to some methodologies, 6 levels of evidence can refer not only to individual studies but also to the quality of evidence from multiple studies about a specific question or the quality of evidence supporting a clinical intervention. For purposes of maintaining simplicity and consistency in this proposal, we use the term “level of evidence” to refer to individual studies.

Strength of Recommendation

The strength (or grade) of a recommendation for clinical practice is based on a body of evidence (typically more than one study). This approach takes into account the level of evidence of individual studies; the type of outcomes measured by these studies (patient-oriented or disease-oriented); the number, consistency, and coherence of the evidence as a whole; and the relationship between benefits, harms, and costs.

Practice Guideline (Evidence-Based)

These guidelines are recommendations for practice that involve a comprehensive search of the literature, an evaluation of the quality of individual studies, and recommendations that are graded to reflect the quality of the supporting evidence. All search, critical appraisal, and grading methods should be described explicitly and be replicable by similarly skilled authors.

Practice Guideline (Consensus)

Consensus guidelines are recommendations for practice based on expert opinions that typically do not include a systematic search, an assessment of the quality of individual studies, or a system to label the strength of recommendations explicitly.

Research Evidence

This evidence is presented in publications of original research, involving collection of original data or the systematic review of other original research publications. It does not include editorials, opinion pieces, or review articles (other than systematic reviews or meta-analyses).

Review Article

A nonsystematic overview of a topic is a review article. In most cases, it is not based on an exhaustive, structured review of the literature and does not evaluate the quality of included studies systematically.

Systematic Reviews and Meta-Analyses

A systematic review is a critical assessment of existing evidence that addresses a focused clinical question, includes a comprehensive literature search, appraises the quality of studies, and reports results in a systematic manner. If the studies report comparable quantitative data and have a low degree of variation in their findings, a meta-analysis can be performed to derive a summary estimate of effect.

Existing Strength-of-Evidence Scales

In March 2002, the Agency for Healthcare Research and Quality (AHRQ) published a report that summarized the state-of-the-art in methods of rating the strength of evidence. 5 The report identified a large number of systems for rating the quality of individual studies: 20 for systematic reviews, 49 for randomized controlled trials, 19 for observational studies, and 18 for diagnostic test studies. It also identified 40 scales that graded the strength of a body of evidence consisting of one or more studies.

The authors of the AHRQ report proposed that any system for grading the strength of evidence should consider three key elements: quality, quantity, and consistency. Quality is the extent to which the identified studies minimize the opportunity for bias and is synonymous with the concept of validity. Quantity is the number of studies and subjects included in those studies. Consistency is the extent to which findings are similar between different studies on the same topic. Only seven of the 40 systems identified and addressed all three of these key elements. 6 – 11

Strength of Recommendation Taxonomy (SORT)

The authors of this article represent the major family medicine journals in the United States and a large family medicine academic consortium. Our process began with a series of e-mail exchanges, was developed during a meeting of the editors, and continued through another series of e-mail exchanges.

We decided that our taxonomy for rating the strength of a recommendation should address the three key elements identified in the AHRQ report: quality, quantity, and consistency of evidence. We also were committed to creating a grading scale that could be applied by authors with varying degrees of expertise in evidence-based medicine and clinical epidemiology, and interpreted by physicians with little or no formal training in these areas. We believed that the taxonomy should address the issue of patient-oriented evidence versus disease-oriented evidence explicitly and be consistent with the information mastery framework proposed by Slawson and Shaughnessy. 2

After considering these criteria and reviewing the existing taxonomies for grading the strength of a recommendation, we decided that a new taxonomy was needed to reflect the needs of our specialty. Existing grading scales were focused on a particular kind of study (e.g., prevention or treatment), were too complex, or did not take into account the type of outcome.

Our proposed taxonomy is called the Strength of Recommendation Taxonomy (SORT). It is shown in Figure 1 . The taxonomy includes ratings of A, B, or C for the strength of recommendation for a body of evidence. The table in the center of Figure 1 explains whether a body of evidence represents good-quality or limited-quality evidence, and whether evidence is consistent or inconsistent. The quality of individual studies is rated 1, 2, or 3; numbers are used to distinguish ratings of individual studies from the letters A, B, and C used to evaluate the strength of a recommendation based on a body of evidence. Figure 2 provides information about how to determine the strength of recommendation for management recommendations, and Figure 3 explains how to determine the level of evidence for an individual study. These two algorithms should be helpful to authors preparing papers for submission to family medicine journals. The algorithms are to be considered general guidelines, and special circumstances may dictate assignment of a different strength of recommendation (e.g., a single, large, well-designed study in a diverse population may warrant an A-level recommendation).

Recommendations based only on improvements in surrogate or disease-oriented outcomes are always categorized as level C, because improvements in disease-oriented outcomes are not always associated with improvements in patient-oriented outcomes, as exemplified by several well-known findings from the medical literature. For example, doxazosin lowers blood pressure in black patients—a seemingly beneficial outcome—but it also increases mortality rates. 12 Similarly, encainide and flecainide reduce the incidence of arrhythmias after acute myocardial infarction, but they also increase mortality rates. 13 Finasteride improves urinary flow rates, but it does not significantly improve urinary tract symptoms in patients with benign prostatic hypertrophy, 14 while arthroscopic surgery for osteoarthritis of the knee improves the appearance of cartilage but does not reduce pain or improve joint function. 15 Additional examples of clinical situations where disease-oriented evidence conflicts with patient-oriented evidence are shown in Table 1 . 12 – 24 Examples of how to apply the taxonomy are given in Table 2 .

We believe there are several advantages to our proposed taxonomy. It is straightforward and comprehensive, is easily applied by authors and physicians, and explicitly addresses the issue of patient-oriented versus disease-oriented evidence. The latter attribute distinguishes SORT from most other evidence-grading scales. These strengths also create some limitations. Some clinicians may be concerned that the taxonomy is not as detailed in its assessment of study designs as others, such as that of the Centre for Evidence-Based Medicine (CEBM). 25 However, the primary difference between the two taxonomies is that the CEBM version distinguishes between good and poor observational studies while the SORT version does not. We concluded that the advantages of a system that provides the physician with a clear recommendation that is strong (A), moderate (B), or weak (C) in its support of a particular intervention outweighs the theoretic benefit of distinguishing between lower quality and higher quality observational studies, particularly because there is no objective evidence that the latter distinction carries important differences in clinical recommendations.

Any publication applying SORT (or any other evidence-based taxonomy) should describe carefully the search process that preceded the assignment of a SORT rating. For example, authors could perform a comprehensive search of MEDLINE and the gray literature, a comprehensive search of MEDLINE alone, or a more focused search of MEDLINE plus secondary evidence-based sources of information.

Walkovers: Creating Linkages with SORT

Some organizations, such as the CEBM, 25 the Cochrane Collaboration, 7 and the U.S. Preventive Services Task Force, 6 have developed their own grading scales for the strength of recommendation based on a body of evidence and are unlikely to abandon them. Other organizations, such as the FPIN, 26 publish their work in a variety of settings and must be able to move between taxonomies. We have developed a set of optional walkovers that suggest how authors, editors, and readers might move from one taxonomy to another. Walkovers for the CEBM and BMJ Clinical Evidence taxonomies are shown in Table 3 .

Many authors and experts in evidence-based medicine use the “Level of Evidence” taxonomy from the CEBM to rate the quality of individual studies. 25 A walkover from the five-level CEBM scale to the simpler three-level SORT scale for individual studies is shown in Table 4 .

Final Comment

The SORT is a comprehensive taxonomy for evaluating the strength of a recommendation based on a body of evidence and the quality of an individual study. If applied consistently by authors and editors in the family medicine literature, it has the potential to make it easier for physicians to apply the results of research in their practice through the information mastery approach and to incorporate evidence-based medicine into their patient care.

Like any such grading scale, it is a work in progress. As we learn more about biases in study design, and as the authors and readers who use the taxonomy become more sophisticated about principles of information mastery, evidence-based medicine, and critical appraisal, it is likely to evolve. We remain open to suggestions from the primary care community for refining and improving SORT.

Organizing Papers and References without Losing your Mind

In January, Ulrike Träger wrote a great PLOS ECR post describing how to stay on top of reading during graduate school. If you haven’t read it yet, go take a look, as it’s relevant for people at all career stages. As a follow up, here are a few tips on how to keep track of the papers you want to read without losing your mind.

Choose a reference manager. Sure, you can get by creating a poster or two without a reference manager, but it’s incredibly risky to cite references by hand for manuscripts and grant proposals. Choosing and using a reference manager is also a great way to track papers as you collect them, particularly because reference managers often have powerful search functions. There are many to choose from. Some are free, like Zotero and some versions of Mendeley . Others, like Papers and EndNote , are not, though some paid programs may be free through your institution. Spend some time researching which manager fits your needs, but don’t get bogged down, you can always switch later. Personally, I have transferred references from RefWorks to Zotero to Mendeley to EndNote over the past several years without much trouble.

Choose a place to keep unread papers. Whether it’s a physical folder on your desk or a virtual folder on your desktop, it’s important to have a designated place for unread papers. This folder is more than just a storage space, it should also be a reminder for you to review unread papers. It’s tempting to download papers and forget about them, falling prey to PDF alibi syndrome , wherein you fool yourself into thinking that by downloading a paper you’ve somehow read it. So, set aside some time every few weeks (on your calendar if you need to) to review papers. You won’t necessarily read each paper in detail, but you should complete a quick skim and take a few notes. Try to resist the urge to leave notes like “finish reading later.” However, if needed, consider using notes like “need to read again before citing” for papers that were skimmed particularly quickly.

Choose how to keep track of your notes. It’s a great idea to create a summary of each paper as you read it, but where do you keep this information? Some people write separate documents for each paper (e.g., using the Rhetorical Précis Format ), others write nothing at all, but tag papers (virtually or physically) with key words. The exact components of your system matter less than having a system. Right now, I keep a running document with a few sentences about each paper I read. I also note whether I read it on paper or as a PDF so that I can find notes taken on the paper itself later. If I’m doing a deep read on a specific topic, I might also start another document that has in-depth summaries. I usually keep notes in Word documents, but it’s also possible to store these notes in many reference managers.

Choose how to file read papers. Again, having a system probably matters more than which system you choose. Given the interdisciplinary nature of science, it can be complex to file by topic. Therefore, I find it easiest to file papers by last name of the first author and the publication year. It’s also useful to include a few words in the file name that summarize its content. This will help you differentiate between articles written by authors with similar last names. So, for example, using this method, you might label this blog post as Breland_2017_tracking refs. I keep articles I’ve read in a folder labeled “Articles” that includes a folder for each letter of the alphabet. Therefore, I’d file this blog post in the “B” folder for Breland.

TL;DR. The goal of creating a system to organize papers and references is to be able to easily access them later. If you follow the steps above, it’s relatively easy to keep track of and use what you’ve read – if you want to find a paper, you can search for a key word in your reference manager and/or in your running document of article summaries and then find a copy of the paper in the appropriate alphabetized folder. That said, there is no right way to organize references and I’m curious about how others manage their files. Chime in through the comments and we’ll update the post with any interesting answers!

How to Organize Research Papers: A Cheat Sheet for Graduate Students

August 8, 2022
PRODUCTIVITY

It is crucial to organize research papers so that the literature survey process goes smoothly once the data has been gathered and analyzed. This is where a research organizer is useful.

It may be helpful to plan the structure of your writing before you start writing: organizing your ideas before you begin to write will help you decide what to write and how to write it.

It can be challenging to keep your research organized when writing an essay. The truth is, there’s no one “ best ” way to get organized, and there’s no one answer. Whatever system you choose, make sure it works for your learning style and writing habits.

As a graduate student, learning how to organize research papers is therefore essential.

This blog post will cover the basics of organizing research papers and the tools I use to organize my research.

Before you start

The importance of organizing research papers.

No matter how good your paper management system is, even if you keep all your literature in places that are easy to find, you won’t be able to “create” anything unless you haven’t thought about organizing what you get from them.

The goal of the research is to publish your own work to society for the benefit of everyone in the field and, ultimately, humanity.

In your final year of your PhD, when you see all the papers you’ve stored over the years, imagine the frustration you might experience if you hadn’t gathered the information from those papers in a way that allows you to “create” something with i.

This is why organizing research papers is important when starting your research.

Research with your final product in mind

It is very important to have a clear idea of what your research’s outcome will be to collect the information you really need.

If you don’t yet have all your information, consider what “subheadings” or chunks you could write about.

Write a concept map if you need help identifying your topic chunks. As an introduction to concept mapping, it involves writing down a term or idea and then brainstorming other ideas within it.

To gather information like this, you can use a mind map.

When you find useful information.

Come up with a proper file management system.

Sort your literature with a file management system. There’s no need to come up with a very narrow filing system at this point. Try sorting your research into broader areas of your field. When you’re more familiar with your own research, you’ll be able to narrow down your filing system.

Start with these methods:

Don’t waste your time on stuff that’s interesting but not useful :

In your own research, what’s the most important part of a particular paper? You won’t have to pay attention to other sections of that paper if you find that section first.

What is the argument behind your research? Make notes on that information, and then throw everything else away.

Create multiple folders :

Create a file containing related topics if you’re using a computer. Bind the related articles together if you like to print out papers. In other words, keep related things together!

Color code your research papers:

To organize notes and articles, assign different colors to each sub-topic and use highlighters, tabs, or font colors.

Organize your literature chronologically:

Even in a short period of time, you might have missed overarching themes or arguments if you hadn’t read them previously. It’s best to organize your research papers chronologically.

If you want to do all this at once, I suggest using a reference manager like Zotero or Mendeley (more on reference managers later).

File renaming

Make sure you rename your files on your computer according to your own renaming strategy. Taking this step will save you time and confusion as your research progresses.

My usual way of naming a pdf is to use the first author’s last name, followed by the first ten letters of the title and then the year of publication. As an example, For the paper “ Temperature-Dependent Infrared Refractive Index of Polymers from a Calibrated Attenuated Total Reflection Infrared Measurement ” by Azam et al., I renamed the file as “ Azam_Temperature-Dependent_2022.pdf “.

One thing to notice is that I don’t do this manually for all the papers I download. That wouldn’t be as productive, and I’d probably give up after some time renaming every single file. In my reference manager of choice (Zotero), I use a plugin called Zotfile to do this automatically. Zotfile automatically renames files and puts them in the folder I specify every time I add a new paper.

Organizing your research articles by the last names of the lead authors will simplify your citation and referencing process since you have to cite the names of the researchers everywhere. The articles will also be easier to find because they’ll be lined up alphabetically by any researcher’s name you can remember.

Use keywords wisely

Keywords are the most important part of sorting. It’s easy to forget to move a paper to a specific file sometimes because you’re overwhelmed. But you can tag a paper in seconds.

When organizing research papers, don’t forget to develop a better keyword system, especially if you use a reference manager.

My reference manager, for instance, allows me to view all the keywords I have assigned in the main window, making life much easier.

Create annotations

When reading literature, it is very important to create your own annotations, as discussed in the blog post series, “ Bulletproof literature management system “.

This is the fourth post of the four-part blog series: The Bulletproof Literature Management System . Follow the links below to read the other posts in the series:

The best thing to do is to summarize each section of the article/book you are reading that interests you. Don’t forget to include the key parts/arguments/quotes you liked.

Write your own notes

If you decide to read the whole paper, make sure you write your own summary. The reason is that 95% of the things you read will be forgotten after a certain period of time. When that happens, you may have to read the paper all over again if you do not take notes and write your own summary.

By writing your own summary, you will likely memorize the basic idea of the research paper. Additionally, you can link to other similar papers. In this way, you can benefit from the knowledge you gain from reading research papers.

After reading a paper, make sure to ask these questions:

Why is this source helpful for your essay?
How does it support your thesis?

Keep all the relevant information in one place so that you can refer to it when writing your own thesis.

Use an app like Obsidian to link your thinking if you keep all your files on a computer, making things much easier.

When you are ready to write

Write out of order .

Once you have all the necessary information, you can use your filing system, PDF renaming strategy, and keywords to draw the annotations and notes you need.

Now that you’re all set to write, don’t worry about writing the perfect paper or thesis right away.

Your introduction doesn’t have to come first.

If necessary, you can change your introduction at the end – sometimes, your essay takes a different direction. Nothing to worry about!

Write down ideas as they come to you

As you complete your research, many full-sentence paragraphs will come to your mind. Do not forget to write these down – even in your notes or annotations. Keep a notebook or your phone handy to jot down ideas as you get them. You can then find the information and revise it again to develop a better version if you’re working on the same project for a few days/weeks.

My toolbox to organize research papers

Stick with the free stuff.

Trying to be a productive grease monkey, I’ve tried many apps over the years. Here’s what I learned.

The simplest solution is always the best solution (the Occam razor principle always wins!).
The free solution is always the best (because they have the best communities to help you out and are more customizable).

As someone who used to believe that if something is free, you’re the product, I’ve learned that statement isn’t always true.

Ironically, open-source software tends to get better support than proprietary stuff. It’s better to have millions of enthusiasts working for free than ten paid support staff.

There are a lot of reviews out there, and EndNote usually comes out at the bottom. I used EndNote for five years – it worked fine, but other software improved faster. Now I use Zotero, which I like for its web integration.

Obsidian, my note-taking app of choice, is also free software. Furthermore, you own your files; also, you’ve got a thriving community.

There are a lot of similarities between the software as they adopt each other’s features, and it’s just a matter of preference.

In any researcher’s toolbox, a reference manager is an essential tool.

A reference manager has two important features: the ability to get citation data into the app and the ability to use the citation data in your writing tool.

It should also work on Windows just as well as macOS or Linux, be free, and allow you to manage PDFs of papers or scanned book chapters.

Zotero , in my opinion, gives you all of this and more.

Zotero is one of the best free reference managers for collecting citation data. It includes a browser plugin that lets you save citation information on Google Scholar, journal pages, YouTube, Amazon, and many other websites, including news articles. It automatically downloads a PDF of the associated source when available for news articles, which is very convenient.

One of the things I really like about Zotero is that it has so many third-party plugins that we have almost complete control over how we use it.

With Zotero 6, you can also read and annotate PDFs, which is perfect for your needs.

My Research paper organizing workflow in Zotero :

Get References and PDF papers into Zotero : I use Zotero’s web plugin to import PDFs directly
Filing and sorting : I save files from the web plugin into the file system I already have created in Zotero and assign tags as I do so.
File renaming : When I save the file, the Zotero plugin (Zotfile) automatically renames it and stores the pdf where I specified.
Extracting Annotations and taking notes : I use Zotero in the build pdf reader to take notes and annotate, and then I extract them and link them in Obsidian (next section).

You need to keep your notes organized and accessible once you’ve established a strong reading habit. For this purpose, I use Obsidian . I use Obsidian to manage everything related to my graduate studies, including notes, projects, and tasks.

Using a plugin called mdnotes , Obsidian can also sync up with my reference manager of choice, Zotero. It automatically adds new papers to my Obsidian database whenever I add them to Zotero.

Obsidian may have a steep learning curve for those unfamiliar with bi-directional linking , but using similar software will make things much easier. Thus, you may be better off investing your time in devising a note-taking system that works for you.

You can also use a spreadsheet! Make a table with all the papers you read, whatever tool you choose. Include the paper’s status (e.g., whether you’ve read it) and any relevant projects. This is what mine looks like.

I keep all my notes on an associated page for each paper. In a spreadsheet, you can write your notes directly in the row or link to a Google document for each row. Zotero, for example, allows you to attach notes directly to reference files.

While it might seem like a lot of work, keeping a database of papers you’ve read helps with literature reviews, funding applications, and more. I can filter by keywords or relevant projects, so I don’t have to re-read anything.

The habit of reading papers and learning how to organize research papers has made me a better researcher. It takes me much less time to read now, and I use it to improve my experiments. I used this system a lot when putting together my PhD fellowship application and my candidacy exam. In the future, I will thank myself for having the foresight to take these steps today before starting to write my dissertation.

I am curious to know how others organize their research papers since there is no “ right ” way. Feel free to comment, and we will update the post with any interesting responses!

Organizing Research Papers: A Step-by-Step Guide

Writing research papers can be an arduous task, especially when it comes to organizing the materials needed for a successful paper. In order to simplify this process, this article will provide a step-by-step guide on how to effectively organize your research papers. It will discuss topics such as where and how to store information, proper citing practices, effective note taking strategies and more in depth guidance that is essential for producing quality work. By following these instructions you will not only save time but also produce better results from your efforts in writing comprehensive research papers.

I. Introduction to Organizing Research Papers

Ii. benefits of an effective research paper organization system.

III. Creating a Research Plan: A Step-by-Step Guide

IV. The Importance of Properly Formatting and Referencing Sources

V. utilizing index cards for topic outlining and categorization, vi. constructing file folders to store relevant materials efficiently, vii . conclusion: implementing structured strategies for long-term success.

Research papers can be a daunting task for any student. To make the process easier, it’s important to have an organized approach . A research paper organizer helps keep all of your notes and resources in one place so that you don’t miss anything or lose focus while writing. It also allows you to easily search for relevant information and quickly move between sources.

An easy way to start organizing is by using a basic outline format with headers and subheaders such as: I. Introduction; II. Background Information; III. Methodology & Results; IV Conclusion & Future Directions.

The introduction should provide context on why the topic is being discussed and how your work relates.
Background info should include prior works related to the topic from other authors, if applicable.
Methodology outlines what data was collected, how it was analyzed, etc..

Maximizing the Outcomes of Research Paper Writing Organization is a crucial part in producing an effective research paper. Having a systematic system to structure one’s work will yield results that are both productive and efficient, especially when it comes to meeting deadlines. A research paper organizer can help organize ideas before committing them onto written form. This allows for more structured thought process with better clarity on which information should be included or excluded from the final product. The use of an organized approach can lead to higher-quality outputs as well as increased productivity overall due to less time spent revising after submission deadline passes. It is also easier for readers or evaluators of the document follow through its content if there exists a logical flow between sections instead of having all arguments scattered throughout the entire page without any tangible direction linking these together.

Furthermore, organizing one’s thoughts with the aid of devices such as color coding makes it simpler to navigate within texts by visually highlighting important points while potentially disregarding those that may not be necessary at first glance; allowing researchers better efficiency in identifying which areas need further examination or expansion upon during their writing journey thus creating an effective organizational tool for researchers looking improve their quality and increase output timeliness.

Color Coding:

A simple yet highly useful organization technique used in arranging text.

Research Paper Organizer:

Developing a Research Plan: Creating an effective research plan is essential for successful execution of the project. It involves formulating questions, selecting appropriate sources and materials, establishing timelines and budgets, and outlining tasks that need to be completed. Here is a step-by-step guide to help you create your own customized research plan:

Establish Your Goals – Start by deciding what information or results you hope to gain from your project.
Research Paper Organizer – Use this tool to keep track of references used in the paper as well as other relevant resources.

Organize Resources & Collect Data – Establish parameters for data collection (e.g., type of source material). Gather all relevant documents, reports, articles etc that support your goal objectives.

Outline Tasks – Draft up a comprehensive list outlining steps necessary for completion.

Create Timeline/Set Deadlines – Set deadlines for each task along with due dates on key milestones such as drafts , revisions etc Finally , develop an efficient system so you can stay on top of everything . Monitor progress frequently while remaining flexible enough if changes have to be made midway through .

Correctly Citing Sources and Proper Formatting Enhance Academic Writing It is essential for students to properly cite sources when writing an academic paper. Proper citation allows readers to identify the origin of borrowed ideas, thoughts, and information used in a text. Additionally, correctly citing sources helps authors avoid accusations of plagiarism which can lead to serious consequences including failure on assignments or even expulsion from college. Referencing outside materials also provides authors with credibility since they are able to back up their work with reliable evidence that has been obtained by other well-respected professionals within a field of study. To ensure proper citations are utilized throughout an entire paper, writers should create a research paper organizer . This will help them remember all applicable references as well as provide them with accurate formatting information such as:

The typeface size.
Spacing between lines.

Moreover, correctly referencing sources can also add value to one’s own written work due it allowing others potential access into other related fields of research often generated by experts in those respective areas; thus providing readers with further points for consideration not originally included within the body itself. Therefore following correct source formats gives any writer additional insight into topics being discussed while strengthening his/her argument overall through useful contextual support sourced externally beyond their original scope of content generation alone.

Organizing Ideas with Index Cards Index cards are an excellent tool for organizing ideas and structuring research papers. Not only do they help keep information organized, but index cards also allow you to quickly move around pieces of your project as needed while keeping everything together in one place.

Using the right colors for different categories can make a big difference when it comes to sorting through data. For example, red could be used to designate all primary sources; yellow could denote secondary sources; green or blue might identify keywords associated with the topic being researched. Once each card has been properly labeled and categorized, using them becomes much easier because you know exactly where everything should go!

An easy way to organize multiple lines of thought is by writing a main idea on an individual card then taping several other related cards underneath it. This makes for quick access when trying to find certain notes at a later date – just flip over the original card and voila! It’s like having your own personal research paper organizer.

Create separate sections in notebooks (or on digital documents) so that changes can be made without compromising existing work.
Label each page according to its category—for instance: “Primary Sources” or “Secondary Sources”.

Having this system allows researchers not only track progress but easily refer back if necessary. Assembling topics into logical sequences is another key component when utilizing index cards during outlining stages — use numbering systems that connect subtopics under headings so they’re more cohesive upon completion

Organizing Your Research Materials

Research papers can quickly become overwhelming if materials are not stored in an organized manner. One of the most efficient ways to keep everything together is by constructing file folders for each research paper topic you cover. You can use any type of filing system such as manila files, plastic folders or online documents that all store information related to a particular project.

When making your folder, it’s important to remember what materials need to be included within the designated space. This may include:

Drafts and outlines of research papers
Notes from relevant books, articles and other sources
Audio recordings from interviews conducted

Any items that could help further support your paper should also be saved along with these above materials – creating a comprehensive research paper organizer. Keep all physical copies in labeled manilla envelopes so they don’t get mixed up while digital versions can stay sorted on different drives or external hard disks. Having this organized will save time when having to refer back at some point during the writing process.

Structured strategies are essential for achieving long-term success in any endeavor. To that end, there have been a number of research studies exploring the various elements of successful strategy implementation.

Motivation: What drives individuals and organizations to achieve success?

The key is not only setting realistic objectives but also having a comprehensive approach when it comes time for implementing those objectives. This requires an understanding of the particular context in which the organization finds itself—which means being aware of both internal and external factors such as technological advancements, changes in consumer tastes, or economic cycles—and taking steps toward bridging any gaps between current capabilities and desired outcomes. Companies should take a holistic view when constructing their strategies, making sure each element serves its own unique purpose while working together with others towards common goal attainment over time.

As this step-by-step guide to organizing research papers illustrates, a well thought out and organized approach can save time and ensure more successful research outcomes. By following the outlined steps from creating a preliminary structure to utilizing efficient information retrieval systems, researchers can easily refine their process in order to maximize productivity while still producing quality results. It is imperative that those conducting research remain cognizant of the importance of organization for not only successful completion but also for ethical considerations related to reproducibility and accuracy of data collection methods. Such intentional structuring should be applied consistently throughout all stages of the project’s lifecycle in order create greater efficiencies in both time management as well as resources used along the way—ultimately resulting in higher quality output with fewer missteps along the path toward success.

An outline is a formal system used to develop a framework for thinking about what the eventual contents and organization of your paper should be. An outline helps you predict the overall structure and flow of a paper.

Importance of...

Writing papers in college requires you to come up with sophisticated, complex, and sometimes very creative ways of structuring your ideas . Taking the time to draft an outline can help you see whether your ideas connect to each other, what order of ideas works best, where gaps in your thinking may exist, or whether you have sufficient evidence to support each of your points.

A good outline is important because :

You will be much less likely to get writer's block because an outline will show where you're going and what the next step is.
It will help you stay organized and focused throughout the writing process and helps ensure a proper coherence [flow of ideas] in your final paper. However, the outline should be viewed as a guide, not a straitjacket.
A clear, detailed outline ensures that you always have something to help re-calibrate your writing should you feel yourself drifting into subject areas unrelated to the larger research problem.
The outline can be key to staying motivated . You can put together an outline when you're excited about the project and everything is clicking; making an outline is never as overwhelming as sitting down and beginning to write a twenty page paper without any sense of where it is going.
An outline help you organize multiple ideas about a topic . Most research problems can be analyzed in any number of inter-related ways; an outline can help you sort out which modes of analysis are most appropriate or ensure the most robust findings.

How to Structure and Organize Your Paper . Odegaard Writing & Research Center. University of Washington.

Structure and Writing Style

I. General Approaches

There are two general approaches you can take when writing an outline for your paper:

The topic outline consists of short phrases. This approach is useful when you are dealing with a number of different issues that could be arranged in a variety of different ways in your paper. Due to short phrases having more content than using simple sentences, they create better content from which to build your paper.

The sentence outline is done in full sentences. This approach is useful when your paper focuses on complex issues in detail. The sentence outline is also useful because sentences themselves have many of the details in them and it allows you to include those details in the sentences instead of having to create an outline of many short phrases that goes on page after page.

II. Steps to Making the Outline

A strong outline details each topic and subtopic in your paper, organizing these points so that they build your argument toward an evidence-based conclusion. Writing an outline will also help you focused on the task at hand and avoid unnecessary tangents, logical fallacies, and underdeveloped paragraphs.

Identify the research problem . The research problem is the focal point from which the rest of the outline flows. Try to sum up the point of your paper in one sentence or phrase. It also can be key to deciding what the title of your paper should be.
Identify the main categories . What main points will you analyze? The introduction describes all of your main points, the rest of your paper can be spent developing those points.
Create the first category . What is the first point you want to cover? If the paper centers around a complicated term, a definition can be a good place to start. For a paper about a particular theory, giving the general background on the theory can be a good place to begin.
Create subcategories . After you have the main point, create points under it that provide support for the main point. The number of categories that you use depends on the amount of information that you are trying to cover; there is no right or wrong number to use.

Once you have developed the basic outline of the paper, organize the contents to match the standard format of a research paper as described in this guide.

III. Things to Consider When Writing an Outline

There is no rule dictating which approach is best . Choose either a topic outline or a sentence outline based on which one you believe will work best for you. However, once you begin developing an outline, it's helpful to stick to only one approach.
Both topic and sentence outlines use Roman and Arabic numerals along with capital and small letters of the alphabet arranged in a consistent and rigid sequence. A rigid format should be used especially if you are required to hand in your outline.
Although the format of an outline is rigid, it shouldn't make you inflexible about how to write your paper. Often when you start investigating a research problem [i.e., reviewing the research literature], especially if you are unfamiliar with the topic, you should anticipate the likelihood your analysis could go in different directions. If your paper changes focus, or you need to add new sections, then feel free to reorganize the outline.
If appropriate, organize the main points of your outline in chronological order . In papers where you need to trace the history or chronology of events or issues, it is important to arrange your outline in the same manner, knowing that it's easier to re-arrange things now than when you've almost finished your paper.
For a standard research paper of 15-20 pages, your outline should be no more than four pages in length . It may be helpful as your are developing your outline to also jot down a tentative list of references.

Writing Tip

A Disorganized Outline Means a Disorganized Paper!

If, in writing your paper, it begins to diverge from your outline, this is very likely a sign that you've lost your focus. How do you know whether to change the paper to fit the outline, or, that you need to reconsider the outline so that fits the paper? A good way to check yourself is to use what you have written to recreate the outline. This is an effective strategy for assessing the organization of your paper. If the resulting outline says what you want it to say and it is in an order that is easy to follow, then the organization of your paper has been successful. If you discover that it's difficult to create an outline from what you have written, then you likely need to revise your paper.

How to write a research paper

Last updated

11 January 2024

Reviewed by

With proper planning, knowledge, and framework, completing a research paper can be a fulfilling and exciting experience.

Though it might initially sound slightly intimidating, this guide will help you embrace the challenge.

By documenting your findings, you can inspire others and make a difference in your field. Here's how you can make your research paper unique and comprehensive.

What is a research paper?

Research papers allow you to demonstrate your knowledge and understanding of a particular topic. These papers are usually lengthier and more detailed than typical essays, requiring deeper insight into the chosen topic.

To write a research paper, you must first choose a topic that interests you and is relevant to the field of study. Once you’ve selected your topic, gathering as many relevant resources as possible, including books, scholarly articles, credible websites, and other academic materials, is essential. You must then read and analyze these sources, summarizing their key points and identifying gaps in the current research.

You can formulate your ideas and opinions once you thoroughly understand the existing research. To get there might involve conducting original research, gathering data, or analyzing existing data sets. It could also involve presenting an original argument or interpretation of the existing research.

Writing a successful research paper involves presenting your findings clearly and engagingly, which might involve using charts, graphs, or other visual aids to present your data and using concise language to explain your findings. You must also ensure your paper adheres to relevant academic formatting guidelines, including proper citations and references.

Overall, writing a research paper requires a significant amount of time, effort, and attention to detail. However, it is also an enriching experience that allows you to delve deeply into a subject that interests you and contribute to the existing body of knowledge in your chosen field.

How long should a research paper be?

Research papers are deep dives into a topic. Therefore, they tend to be longer pieces of work than essays or opinion pieces.

However, a suitable length depends on the complexity of the topic and your level of expertise. For instance, are you a first-year college student or an experienced professional?

Also, remember that the best research papers provide valuable information for the benefit of others. Therefore, the quality of information matters most, not necessarily the length. Being concise is valuable.

Following these best practice steps will help keep your process simple and productive:

1. Gaining a deep understanding of any expectations

Before diving into your intended topic or beginning the research phase, take some time to orient yourself. Suppose there’s a specific topic assigned to you. In that case, it’s essential to deeply understand the question and organize your planning and approach in response. Pay attention to the key requirements and ensure you align your writing accordingly.

This preparation step entails

Deeply understanding the task or assignment

Being clear about the expected format and length

Familiarizing yourself with the citation and referencing requirements

Understanding any defined limits for your research contribution

Where applicable, speaking to your professor or research supervisor for further clarification

2. Choose your research topic

Select a research topic that aligns with both your interests and available resources. Ideally, focus on a field where you possess significant experience and analytical skills. In crafting your research paper, it's crucial to go beyond summarizing existing data and contribute fresh insights to the chosen area.

Consider narrowing your focus to a specific aspect of the topic. For example, if exploring the link between technology and mental health, delve into how social media use during the pandemic impacts the well-being of college students. Conducting interviews and surveys with students could provide firsthand data and unique perspectives, adding substantial value to the existing knowledge.

When finalizing your topic, adhere to legal and ethical norms in the relevant area (this ensures the integrity of your research, protects participants' rights, upholds intellectual property standards, and ensures transparency and accountability). Following these principles not only maintains the credibility of your work but also builds trust within your academic or professional community.

For instance, in writing about medical research, consider legal and ethical norms, including patient confidentiality laws and informed consent requirements. Similarly, if analyzing user data on social media platforms, be mindful of data privacy regulations, ensuring compliance with laws governing personal information collection and use. Aligning with legal and ethical standards not only avoids potential issues but also underscores the responsible conduct of your research.

3. Gather preliminary research

Once you’ve landed on your topic, it’s time to explore it further. You’ll want to discover more about available resources and existing research relevant to your assignment at this stage.

This exploratory phase is vital as you may discover issues with your original idea or realize you have insufficient resources to explore the topic effectively. This key bit of groundwork allows you to redirect your research topic in a different, more feasible, or more relevant direction if necessary.

Spending ample time at this stage ensures you gather everything you need, learn as much as you can about the topic, and discover gaps where the topic has yet to be sufficiently covered, offering an opportunity to research it further.

4. Define your research question

To produce a well-structured and focused paper, it is imperative to formulate a clear and precise research question that will guide your work. Your research question must be informed by the existing literature and tailored to the scope and objectives of your project. By refining your focus, you can produce a thoughtful and engaging paper that effectively communicates your ideas to your readers.

5. Write a thesis statement

A thesis statement is a one-to-two-sentence summary of your research paper's main argument or direction. It serves as an overall guide to summarize the overall intent of the research paper for you and anyone wanting to know more about the research.

A strong thesis statement is:

Concise and clear: Explain your case in simple sentences (avoid covering multiple ideas). It might help to think of this section as an elevator pitch.

Specific: Ensure that there is no ambiguity in your statement and that your summary covers the points argued in the paper.

Debatable: A thesis statement puts forward a specific argument––it is not merely a statement but a debatable point that can be analyzed and discussed.

Here are three thesis statement examples from different disciplines:

Psychology thesis example: "We're studying adults aged 25-40 to see if taking short breaks for mindfulness can help with stress. Our goal is to find practical ways to manage anxiety better."

Environmental science thesis example: "This research paper looks into how having more city parks might make the air cleaner and keep people healthier. I want to find out if more green spaces means breathing fewer carcinogens in big cities."

UX research thesis example: "This study focuses on improving mobile banking for older adults using ethnographic research, eye-tracking analysis, and interactive prototyping. We investigate the usefulness of eye-tracking analysis with older individuals, aiming to spark debate and offer fresh perspectives on UX design and digital inclusivity for the aging population."

6. Conduct in-depth research

A research paper doesn’t just include research that you’ve uncovered from other papers and studies but your fresh insights, too. You will seek to become an expert on your topic––understanding the nuances in the current leading theories. You will analyze existing research and add your thinking and discoveries. It's crucial to conduct well-designed research that is rigorous, robust, and based on reliable sources. Suppose a research paper lacks evidence or is biased. In that case, it won't benefit the academic community or the general public. Therefore, examining the topic thoroughly and furthering its understanding through high-quality research is essential. That usually means conducting new research. Depending on the area under investigation, you may conduct surveys, interviews, diary studies, or observational research to uncover new insights or bolster current claims.

7. Determine supporting evidence

Not every piece of research you’ve discovered will be relevant to your research paper. It’s important to categorize the most meaningful evidence to include alongside your discoveries. It's important to include evidence that doesn't support your claims to avoid exclusion bias and ensure a fair research paper.

8. Write a research paper outline

Before diving in and writing the whole paper, start with an outline. It will help you to see if more research is needed, and it will provide a framework by which to write a more compelling paper. Your supervisor may even request an outline to approve before beginning to write the first draft of the full paper. An outline will include your topic, thesis statement, key headings, short summaries of the research, and your arguments.

9. Write your first draft

Once you feel confident about your outline and sources, it’s time to write your first draft. While penning a long piece of content can be intimidating, if you’ve laid the groundwork, you will have a structure to help you move steadily through each section. To keep up motivation and inspiration, it’s often best to keep the pace quick. Stopping for long periods can interrupt your flow and make jumping back in harder than writing when things are fresh in your mind.

10. Cite your sources correctly

It's always a good practice to give credit where it's due, and the same goes for citing any works that have influenced your paper. Building your arguments on credible references adds value and authenticity to your research. In the formatting guidelines section, you’ll find an overview of different citation styles (MLA, CMOS, or APA), which will help you meet any publishing or academic requirements and strengthen your paper's credibility. It is essential to follow the guidelines provided by your school or the publication you are submitting to ensure the accuracy and relevance of your citations.

11. Ensure your work is original

It is crucial to ensure the originality of your paper, as plagiarism can lead to serious consequences. To avoid plagiarism, you should use proper paraphrasing and quoting techniques. Paraphrasing is rewriting a text in your own words while maintaining the original meaning. Quoting involves directly citing the source. Giving credit to the original author or source is essential whenever you borrow their ideas or words. You can also use plagiarism detection tools such as Scribbr or Grammarly to check the originality of your paper. These tools compare your draft writing to a vast database of online sources. If you find any accidental plagiarism, you should correct it immediately by rephrasing or citing the source.

12. Revise, edit, and proofread

One of the essential qualities of excellent writers is their ability to understand the importance of editing and proofreading. Even though it's tempting to call it a day once you've finished your writing, editing your work can significantly improve its quality. It's natural to overlook the weaker areas when you've just finished writing a paper. Therefore, it's best to take a break of a day or two, or even up to a week, to refresh your mind. This way, you can return to your work with a new perspective. After some breathing room, you can spot any inconsistencies, spelling and grammar errors, typos, or missing citations and correct them.

The best research paper format

The format of your research paper should align with the requirements set forth by your college, school, or target publication.

There is no one “best” format, per se. Depending on the stated requirements, you may need to include the following elements:

Title page: The title page of a research paper typically includes the title, author's name, and institutional affiliation and may include additional information such as a course name or instructor's name.

Table of contents: Include a table of contents to make it easy for readers to find specific sections of your paper.

Abstract: The abstract is a summary of the purpose of the paper.

Methods : In this section, describe the research methods used. This may include collecting data, conducting interviews, or doing field research.

Results: Summarize the conclusions you drew from your research in this section.

Discussion: In this section, discuss the implications of your research. Be sure to mention any significant limitations to your approach and suggest areas for further research.

Tables, charts, and illustrations: Use tables, charts, and illustrations to help convey your research findings and make them easier to understand.

Works cited or reference page: Include a works cited or reference page to give credit to the sources that you used to conduct your research.

Bibliography: Provide a list of all the sources you consulted while conducting your research.

Dedication and acknowledgments : Optionally, you may include a dedication and acknowledgments section to thank individuals who helped you with your research.

General style and formatting guidelines

Formatting your research paper means you can submit it to your college, journal, or other publications in compliance with their criteria.

Research papers tend to follow the American Psychological Association (APA), Modern Language Association (MLA), or Chicago Manual of Style (CMOS) guidelines.

Here’s how each style guide is typically used:

Chicago Manual of Style (CMOS):

CMOS is a versatile style guide used for various types of writing. It's known for its flexibility and use in the humanities. CMOS provides guidelines for citations, formatting, and overall writing style. It allows for both footnotes and in-text citations, giving writers options based on their preferences or publication requirements.

American Psychological Association (APA):

APA is common in the social sciences. It’s hailed for its clarity and emphasis on precision. It has specific rules for citing sources, creating references, and formatting papers. APA style uses in-text citations with an accompanying reference list. It's designed to convey information efficiently and is widely used in academic and scientific writing.

Modern Language Association (MLA):

MLA is widely used in the humanities, especially literature and language studies. It emphasizes the author-page format for in-text citations and provides guidelines for creating a "Works Cited" page. MLA is known for its focus on the author's name and the literary works cited. It’s frequently used in disciplines that prioritize literary analysis and critical thinking.

To confirm you're using the latest style guide, check the official website or publisher's site for updates, consult academic resources, and verify the guide's publication date. Online platforms and educational resources may also provide summaries and alerts about any revisions or additions to the style guide.

Citing sources

When working on your research paper, it's important to cite the sources you used properly. Your citation style will guide you through this process. Generally, there are three parts to citing sources in your research paper:

First, provide a brief citation in the body of your essay. This is also known as a parenthetical or in-text citation.

Second, include a full citation in the Reference list at the end of your paper. Different types of citations include in-text citations, footnotes, and reference lists.

In-text citations include the author's surname and the date of the citation.

Footnotes appear at the bottom of each page of your research paper. They may also be summarized within a reference list at the end of the paper.

A reference list includes all of the research used within the paper at the end of the document. It should include the author, date, paper title, and publisher listed in the order that aligns with your citation style.

10 research paper writing tips:

Following some best practices is essential to writing a research paper that contributes to your field of study and creates a positive impact.

These tactics will help you structure your argument effectively and ensure your work benefits others:

Clear and precise language: Ensure your language is unambiguous. Use academic language appropriately, but keep it simple. Also, provide clear takeaways for your audience.

Effective idea separation: Organize the vast amount of information and sources in your paper with paragraphs and titles. Create easily digestible sections for your readers to navigate through.

Compelling intro: Craft an engaging introduction that captures your reader's interest. Hook your audience and motivate them to continue reading.

Thorough revision and editing: Take the time to review and edit your paper comprehensively. Use tools like Grammarly to detect and correct small, overlooked errors.

Thesis precision: Develop a clear and concise thesis statement that guides your paper. Ensure that your thesis aligns with your research's overall purpose and contribution.

Logical flow of ideas: Maintain a logical progression throughout the paper. Use transitions effectively to connect different sections and maintain coherence.

Critical evaluation of sources: Evaluate and critically assess the relevance and reliability of your sources. Ensure that your research is based on credible and up-to-date information.

Thematic consistency: Maintain a consistent theme throughout the paper. Ensure that all sections contribute cohesively to the overall argument.

Relevant supporting evidence: Provide concise and relevant evidence to support your arguments. Avoid unnecessary details that may distract from the main points.

Embrace counterarguments: Acknowledge and address opposing views to strengthen your position. Show that you have considered alternative arguments in your field.

7 research tips

If you want your paper to not only be well-written but also contribute to the progress of human knowledge, consider these tips to take your paper to the next level:

Selecting the appropriate topic: The topic you select should align with your area of expertise, comply with the requirements of your project, and have sufficient resources for a comprehensive investigation.

Use academic databases: Academic databases such as PubMed, Google Scholar, and JSTOR offer a wealth of research papers that can help you discover everything you need to know about your chosen topic.

Critically evaluate sources: It is important not to accept research findings at face value. Instead, it is crucial to critically analyze the information to avoid jumping to conclusions or overlooking important details. A well-written research paper requires a critical analysis with thorough reasoning to support claims.

Diversify your sources: Expand your research horizons by exploring a variety of sources beyond the standard databases. Utilize books, conference proceedings, and interviews to gather diverse perspectives and enrich your understanding of the topic.

Take detailed notes: Detailed note-taking is crucial during research and can help you form the outline and body of your paper.

Stay up on trends: Keep abreast of the latest developments in your field by regularly checking for recent publications. Subscribe to newsletters, follow relevant journals, and attend conferences to stay informed about emerging trends and advancements.

Engage in peer review: Seek feedback from peers or mentors to ensure the rigor and validity of your research. Peer review helps identify potential weaknesses in your methodology and strengthens the overall credibility of your findings.

The real-world impact of research papers

Writing a research paper is more than an academic or business exercise. The experience provides an opportunity to explore a subject in-depth, broaden one's understanding, and arrive at meaningful conclusions. With careful planning, dedication, and hard work, writing a research paper can be a fulfilling and enriching experience contributing to advancing knowledge.

How do I publish my research paper?

Many academics wish to publish their research papers. While challenging, your paper might get traction if it covers new and well-written information. To publish your research paper, find a target publication, thoroughly read their guidelines, format your paper accordingly, and send it to them per their instructions. You may need to include a cover letter, too. After submission, your paper may be peer-reviewed by experts to assess its legitimacy, quality, originality, and methodology. Following review, you will be informed by the publication whether they have accepted or rejected your paper.

What is a good opening sentence for a research paper?

Beginning your research paper with a compelling introduction can ensure readers are interested in going further. A relevant quote, a compelling statistic, or a bold argument can start the paper and hook your reader. Remember, though, that the most important aspect of a research paper is the quality of the information––not necessarily your ability to storytell, so ensure anything you write aligns with your goals.

Research paper vs. a research proposal—what’s the difference?

While some may confuse research papers and proposals, they are different documents.

A research proposal comes before a research paper. It is a detailed document that outlines an intended area of exploration. It includes the research topic, methodology, timeline, sources, and potential conclusions. Research proposals are often required when seeking approval to conduct research.

A research paper is a summary of research findings. A research paper follows a structured format to present those findings and construct an argument or conclusion.

Comparative of Advanced Sorting Algorithms (Quick Sort, Heap Sort, Merge Sort, Intro Sort, Radix Sort) Based on Time and Memory Usage

Implementation of bubble sort algorithm on 2 fruit models of data selection using the java program language.

There are various kinds of data sorting methods that we know of which are the Bubble Sort, Selection Sort, Insertion Sort, Quick Sort, Shell Sort, Heap Sort, and Radix Sort methods. All of these methods have advantages and disadvantages of each, whose use is determined based on needs. Each method has a different algorithm, where different algorithms affect the execution time. One interesting algorithm to be implemented on 2 variant models of data sorting is the Bubble Sort algorithm, the reason is that this algorithm has a fairly long and detailed process flow to produce an ordered data sequence from a previously unordered data sequence. Two (2) data sorting variant models that will be implemented using the Bubble Sort algorithm are: Ascending data sorting variants moving from left to right, and Descending data sorting variants moving from left to right. And the device used in implementing the Bubble Sort algorithm is the Java programming language.

Comparison of Bubble and Insertion Sort in Rust and Python Language

Sorting is the basic activity in the field of computer science and it is commonly used in searching for information and data. The main goal of sorting is to make reports or records easier to edit, delete and search, etc. It organizes the given data in any sequence. There are many sorting algorithms like insertion sort, bubble sort, radix sort, heap sort, and so forth. Bubble sort and insertion sort are clearly described with algorithms and examples. In this paper, the bubble sort and insertion sort performance analysis is carried out by calculating the time complexity. These algorithm time complexities have been calculated by implementing in the rust and python languages and observed the best case, average case, and worst case. The flowchart shows the complete workflow of this study. The results have been shown graphically and time complexity has been shown in a tabular form. We have compared the efficiency of bubble sort and insertion sort algorithms in the rust and python platforms. The rust language is more efficient than python for both bubble and insertion sort algorithms. However, it is observed insertion sort is more efficient than the bubble sort algorithm.

Improved Parallel DBSCAN Algorithm Based on Radix Sort

Recombinant sort: n-dimensional cartesian spaced algorithm designed from synergetic combination of hashing, bucket, counting and radix sort.

Sorting is an essential operation which is widely used and is fundamental to some very basic day to day utilities like searches, databases, social networks and much more. Optimizing this basic operation in terms of complexity as well as efficiency is cardinal. Optimization is achieved with respect to space and time complexities of the algorithm. In this paper, a novel left-field N-dimensional cartesian spaced sorting method is proposed by combining the best characteristics of bucket sort, counting sort and radix sort, in addition to employing hashing and dynamic programming for making the method more efficient. Comparison between the proposed sorting method and various existing sorting methods like bubble sort, insertion sort, selection sort, merge sort, heap sort, counting sort, bucket sort, etc., has also been performed. The time complexity of the proposed model is estimated to be linear i.e.

ANALISA KOMPUTASI PARALEL MENGURUTKAN DATA DENGAN METODE RADIX DAN SELECTION

Increasing computing power is now achieved by replacing the programming paradigm with parallel programming. Parallel computing is a method of solving problems by dividing the computational load into small parts of the computation sub-process. This study describes the comparative analysis of parallel computations in the Selection Sort and Radix Sort algorithms. The data used are in the form of whole numbers and decimal numbers totaling 100 to 2 million data. The test was carried out with three scenarios, namely using two processors, four processors, and 3 computers connected to each other via a LAN network. The results showed that the parallel Selection Sort algorithm for small data was better than the parallel Radix Sort. On the other hand, parallel Radix Sort is better for millions of data than Selection Sort.

High-Performance Parallel Radix Sort on FPGA

An interesting discussion of running time for some sorting techniques without comparison sort.

Sorting is one of important techniques for computer science as well as other technology areas; sorting is used mostly in searching, database management systems, scheduling, and computing algorithms. This paper aims to analyze the timing cost for some sorting techniques without comparison sorting such as Pigeonhole sort, Counting sort, Radix sort, and Bucket sort; these are sorting techniques with linear running time. Each technique is considered in running time, in-place, stable, and extra space if possible. The main contribution of the paper is experiments of sorting techniques in 90 large size test data. This is also a useful reference for working with sorting techniques.

A Study of Integer Sorting on Multicores

Integer sorting on multicores and GPUs can be realized by a variety of approaches that include variants of distribution-based methods such as radix-sort, comparison-oriented algorithms such as deterministic regular sampling and random sampling parallel sorting, and network-based algorithms such as Batcher’s bitonic sorting algorithm. In this work we present an experimental study of integer sorting on multicore processors. We have implemented serial and parallel radix-sort for various radixes, deterministic regular oversampling, and random oversampling parallel sorting, including new variants of ours, and also some previously little explored or unexplored variants of bitonic-sort and odd-even transposition sort. The study uses multithreading and multiprocessing parallel programming libraries with the same C language code working under Open MPI, MulticoreBSP, and BSPlib. We first provide some general high-level observations on the performance of these implementations. If we can conclude anything is that accurate prediction of performance by taking into consideration architecture dependent features such as the structure and characteristics of multiple memory hierarchies is difficult and more often than not untenable. To some degree this is affected by the overhead imposed by the high-level library used in the programming effort. Another objective is to model the performance of these algorithms and their implementations under the MBSP (Multi-memory BSP) model. Despite the limitations mentioned above, we can still draw some reliable conclusions and reason about the performance of these implementations using the MBSP model, thus making MBSP useful and usable.

Positive Region Reduct Based on Relative Discernibility and Acceleration Strategy

Attribute reduction is one of key issues in rough set theory, and positive region reduct is a classical type of reducts. However, a lot of reduction algorithms have more high time expenses when dealing with high-volume and high-dimensional data sets. To overcome this shortcoming, in this paper, a relative discernibility reduction method based on the simplified decision table of the original decision table is researched for obtaining positive region reduct. Moreover, to further improve performance of reduction algorithm, we develop an accelerator for attribute reduction, which reduces the radix sort times of the reduction process to raise algorithm efficiency. By the accelerator, two positive region reduction algorithms, i.e., FARA-RS and BARA-RS, based on the relative discernibility are designed. FARA-RS simultaneously reduce the size of the universe and the number of radix sort to achieve speedup and BARA-RS only reduce the number of radix sort to achieve acceleration. The experimental results show that the proposed reduction algorithms are effective and feasible for high dimensional and large data sets.

Writing Survey Questions

Perhaps the most important part of the survey process is the creation of questions that accurately measure the opinions, experiences and behaviors of the public. Accurate random sampling will be wasted if the information gathered is built on a shaky foundation of ambiguous or biased questions. Creating good measures involves both writing good questions and organizing them to form the questionnaire.

Questionnaire design is a multistage process that requires attention to many details at once. Designing the questionnaire is complicated because surveys can ask about topics in varying degrees of detail, questions can be asked in different ways, and questions asked earlier in a survey may influence how people respond to later questions. Researchers are also often interested in measuring change over time and therefore must be attentive to how opinions or behaviors have been measured in prior surveys.

Surveyors may conduct pilot tests or focus groups in the early stages of questionnaire development in order to better understand how people think about an issue or comprehend a question. Pretesting a survey is an essential step in the questionnaire design process to evaluate how people respond to the overall questionnaire and specific questions, especially when questions are being introduced for the first time.

For many years, surveyors approached questionnaire design as an art, but substantial research over the past forty years has demonstrated that there is a lot of science involved in crafting a good survey questionnaire. Here, we discuss the pitfalls and best practices of designing questionnaires.

Question development

There are several steps involved in developing a survey questionnaire. The first is identifying what topics will be covered in the survey. For Pew Research Center surveys, this involves thinking about what is happening in our nation and the world and what will be relevant to the public, policymakers and the media. We also track opinion on a variety of issues over time so we often ensure that we update these trends on a regular basis to better understand whether people’s opinions are changing.

At Pew Research Center, questionnaire development is a collaborative and iterative process where staff meet to discuss drafts of the questionnaire several times over the course of its development. We frequently test new survey questions ahead of time through qualitative research methods such as focus groups , cognitive interviews, pretesting (often using an online, opt-in sample ), or a combination of these approaches. Researchers use insights from this testing to refine questions before they are asked in a production survey, such as on the ATP.

Measuring change over time

Many surveyors want to track changes over time in people’s attitudes, opinions and behaviors. To measure change, questions are asked at two or more points in time. A cross-sectional design surveys different people in the same population at multiple points in time. A panel, such as the ATP, surveys the same people over time. However, it is common for the set of people in survey panels to change over time as new panelists are added and some prior panelists drop out. Many of the questions in Pew Research Center surveys have been asked in prior polls. Asking the same questions at different points in time allows us to report on changes in the overall views of the general public (or a subset of the public, such as registered voters, men or Black Americans), or what we call “trending the data”.

When measuring change over time, it is important to use the same question wording and to be sensitive to where the question is asked in the questionnaire to maintain a similar context as when the question was asked previously (see question wording and question order for further information). All of our survey reports include a topline questionnaire that provides the exact question wording and sequencing, along with results from the current survey and previous surveys in which we asked the question.

The Center’s transition from conducting U.S. surveys by live telephone interviewing to an online panel (around 2014 to 2020) complicated some opinion trends, but not others. Opinion trends that ask about sensitive topics (e.g., personal finances or attending religious services ) or that elicited volunteered answers (e.g., “neither” or “don’t know”) over the phone tended to show larger differences than other trends when shifting from phone polls to the online ATP. The Center adopted several strategies for coping with changes to data trends that may be related to this change in methodology. If there is evidence suggesting that a change in a trend stems from switching from phone to online measurement, Center reports flag that possibility for readers to try to head off confusion or erroneous conclusions.

Open- and closed-ended questions

One of the most significant decisions that can affect how people answer questions is whether the question is posed as an open-ended question, where respondents provide a response in their own words, or a closed-ended question, where they are asked to choose from a list of answer choices.

For example, in a poll conducted after the 2008 presidential election, people responded very differently to two versions of the question: “What one issue mattered most to you in deciding how you voted for president?” One was closed-ended and the other open-ended. In the closed-ended version, respondents were provided five options and could volunteer an option not on the list.

When explicitly offered the economy as a response, more than half of respondents (58%) chose this answer; only 35% of those who responded to the open-ended version volunteered the economy. Moreover, among those asked the closed-ended version, fewer than one-in-ten (8%) provided a response other than the five they were read. By contrast, fully 43% of those asked the open-ended version provided a response not listed in the closed-ended version of the question. All of the other issues were chosen at least slightly more often when explicitly offered in the closed-ended version than in the open-ended version. (Also see “High Marks for the Campaign, a High Bar for Obama” for more information.)

Researchers will sometimes conduct a pilot study using open-ended questions to discover which answers are most common. They will then develop closed-ended questions based off that pilot study that include the most common responses as answer choices. In this way, the questions may better reflect what the public is thinking, how they view a particular issue, or bring certain issues to light that the researchers may not have been aware of.

When asking closed-ended questions, the choice of options provided, how each option is described, the number of response options offered, and the order in which options are read can all influence how people respond. One example of the impact of how categories are defined can be found in a Pew Research Center poll conducted in January 2002. When half of the sample was asked whether it was “more important for President Bush to focus on domestic policy or foreign policy,” 52% chose domestic policy while only 34% said foreign policy. When the category “foreign policy” was narrowed to a specific aspect – “the war on terrorism” – far more people chose it; only 33% chose domestic policy while 52% chose the war on terrorism.

In most circumstances, the number of answer choices should be kept to a relatively small number – just four or perhaps five at most – especially in telephone surveys. Psychological research indicates that people have a hard time keeping more than this number of choices in mind at one time. When the question is asking about an objective fact and/or demographics, such as the religious affiliation of the respondent, more categories can be used. In fact, they are encouraged to ensure inclusivity. For example, Pew Research Center’s standard religion questions include more than 12 different categories, beginning with the most common affiliations (Protestant and Catholic). Most respondents have no trouble with this question because they can expect to see their religious group within that list in a self-administered survey.

In addition to the number and choice of response options offered, the order of answer categories can influence how people respond to closed-ended questions. Research suggests that in telephone surveys respondents more frequently choose items heard later in a list (a “recency effect”), and in self-administered surveys, they tend to choose items at the top of the list (a “primacy” effect).

Because of concerns about the effects of category order on responses to closed-ended questions, many sets of response options in Pew Research Center’s surveys are programmed to be randomized to ensure that the options are not asked in the same order for each respondent. Rotating or randomizing means that questions or items in a list are not asked in the same order to each respondent. Answers to questions are sometimes affected by questions that precede them. By presenting questions in a different order to each respondent, we ensure that each question gets asked in the same context as every other question the same number of times (e.g., first, last or any position in between). This does not eliminate the potential impact of previous questions on the current question, but it does ensure that this bias is spread randomly across all of the questions or items in the list. For instance, in the example discussed above about what issue mattered most in people’s vote, the order of the five issues in the closed-ended version of the question was randomized so that no one issue appeared early or late in the list for all respondents. Randomization of response items does not eliminate order effects, but it does ensure that this type of bias is spread randomly.

Questions with ordinal response categories – those with an underlying order (e.g., excellent, good, only fair, poor OR very favorable, mostly favorable, mostly unfavorable, very unfavorable) – are generally not randomized because the order of the categories conveys important information to help respondents answer the question. Generally, these types of scales should be presented in order so respondents can easily place their responses along the continuum, but the order can be reversed for some respondents. For example, in one of Pew Research Center’s questions about abortion, half of the sample is asked whether abortion should be “legal in all cases, legal in most cases, illegal in most cases, illegal in all cases,” while the other half of the sample is asked the same question with the response categories read in reverse order, starting with “illegal in all cases.” Again, reversing the order does not eliminate the recency effect but distributes it randomly across the population.

Question wording

The choice of words and phrases in a question is critical in expressing the meaning and intent of the question to the respondent and ensuring that all respondents interpret the question the same way. Even small wording differences can substantially affect the answers people provide.

[View more Methods 101 Videos ]

An example of a wording difference that had a significant impact on responses comes from a January 2003 Pew Research Center survey. When people were asked whether they would “favor or oppose taking military action in Iraq to end Saddam Hussein’s rule,” 68% said they favored military action while 25% said they opposed military action. However, when asked whether they would “favor or oppose taking military action in Iraq to end Saddam Hussein’s rule even if it meant that U.S. forces might suffer thousands of casualties, ” responses were dramatically different; only 43% said they favored military action, while 48% said they opposed it. The introduction of U.S. casualties altered the context of the question and influenced whether people favored or opposed military action in Iraq.

There has been a substantial amount of research to gauge the impact of different ways of asking questions and how to minimize differences in the way respondents interpret what is being asked. The issues related to question wording are more numerous than can be treated adequately in this short space, but below are a few of the important things to consider:

First, it is important to ask questions that are clear and specific and that each respondent will be able to answer. If a question is open-ended, it should be evident to respondents that they can answer in their own words and what type of response they should provide (an issue or problem, a month, number of days, etc.). Closed-ended questions should include all reasonable responses (i.e., the list of options is exhaustive) and the response categories should not overlap (i.e., response options should be mutually exclusive). Further, it is important to discern when it is best to use forced-choice close-ended questions (often denoted with a radio button in online surveys) versus “select-all-that-apply” lists (or check-all boxes). A 2019 Center study found that forced-choice questions tend to yield more accurate responses, especially for sensitive questions. Based on that research, the Center generally avoids using select-all-that-apply questions.

It is also important to ask only one question at a time. Questions that ask respondents to evaluate more than one concept (known as double-barreled questions) – such as “How much confidence do you have in President Obama to handle domestic and foreign policy?” – are difficult for respondents to answer and often lead to responses that are difficult to interpret. In this example, it would be more effective to ask two separate questions, one about domestic policy and another about foreign policy.

In general, questions that use simple and concrete language are more easily understood by respondents. It is especially important to consider the education level of the survey population when thinking about how easy it will be for respondents to interpret and answer a question. Double negatives (e.g., do you favor or oppose not allowing gays and lesbians to legally marry) or unfamiliar abbreviations or jargon (e.g., ANWR instead of Arctic National Wildlife Refuge) can result in respondent confusion and should be avoided.

Similarly, it is important to consider whether certain words may be viewed as biased or potentially offensive to some respondents, as well as the emotional reaction that some words may provoke. For example, in a 2005 Pew Research Center survey, 51% of respondents said they favored “making it legal for doctors to give terminally ill patients the means to end their lives,” but only 44% said they favored “making it legal for doctors to assist terminally ill patients in committing suicide.” Although both versions of the question are asking about the same thing, the reaction of respondents was different. In another example, respondents have reacted differently to questions using the word “welfare” as opposed to the more generic “assistance to the poor.” Several experiments have shown that there is much greater public support for expanding “assistance to the poor” than for expanding “welfare.”

We often write two versions of a question and ask half of the survey sample one version of the question and the other half the second version. Thus, we say we have two forms of the questionnaire. Respondents are assigned randomly to receive either form, so we can assume that the two groups of respondents are essentially identical. On questions where two versions are used, significant differences in the answers between the two forms tell us that the difference is a result of the way we worded the two versions.

One of the most common formats used in survey questions is the “agree-disagree” format. In this type of question, respondents are asked whether they agree or disagree with a particular statement. Research has shown that, compared with the better educated and better informed, less educated and less informed respondents have a greater tendency to agree with such statements. This is sometimes called an “acquiescence bias” (since some kinds of respondents are more likely to acquiesce to the assertion than are others). This behavior is even more pronounced when there’s an interviewer present, rather than when the survey is self-administered. A better practice is to offer respondents a choice between alternative statements. A Pew Research Center experiment with one of its routinely asked values questions illustrates the difference that question format can make. Not only does the forced choice format yield a very different result overall from the agree-disagree format, but the pattern of answers between respondents with more or less formal education also tends to be very different.

One other challenge in developing questionnaires is what is called “social desirability bias.” People have a natural tendency to want to be accepted and liked, and this may lead people to provide inaccurate answers to questions that deal with sensitive subjects. Research has shown that respondents understate alcohol and drug use, tax evasion and racial bias. They also may overstate church attendance, charitable contributions and the likelihood that they will vote in an election. Researchers attempt to account for this potential bias in crafting questions about these topics. For instance, when Pew Research Center surveys ask about past voting behavior, it is important to note that circumstances may have prevented the respondent from voting: “In the 2012 presidential election between Barack Obama and Mitt Romney, did things come up that kept you from voting, or did you happen to vote?” The choice of response options can also make it easier for people to be honest. For example, a question about church attendance might include three of six response options that indicate infrequent attendance. Research has also shown that social desirability bias can be greater when an interviewer is present (e.g., telephone and face-to-face surveys) than when respondents complete the survey themselves (e.g., paper and web surveys).

Lastly, because slight modifications in question wording can affect responses, identical question wording should be used when the intention is to compare results to those from earlier surveys. Similarly, because question wording and responses can vary based on the mode used to survey respondents, researchers should carefully evaluate the likely effects on trend measurements if a different survey mode will be used to assess change in opinion over time.

Question order

Once the survey questions are developed, particular attention should be paid to how they are ordered in the questionnaire. Surveyors must be attentive to how questions early in a questionnaire may have unintended effects on how respondents answer subsequent questions. Researchers have demonstrated that the order in which questions are asked can influence how people respond; earlier questions can unintentionally provide context for the questions that follow (these effects are called “order effects”).

One kind of order effect can be seen in responses to open-ended questions. Pew Research Center surveys generally ask open-ended questions about national problems, opinions about leaders and similar topics near the beginning of the questionnaire. If closed-ended questions that relate to the topic are placed before the open-ended question, respondents are much more likely to mention concepts or considerations raised in those earlier questions when responding to the open-ended question.

For closed-ended opinion questions, there are two main types of order effects: contrast effects ( where the order results in greater differences in responses), and assimilation effects (where responses are more similar as a result of their order).

An example of a contrast effect can be seen in a Pew Research Center poll conducted in October 2003, a dozen years before same-sex marriage was legalized in the U.S. That poll found that people were more likely to favor allowing gays and lesbians to enter into legal agreements that give them the same rights as married couples when this question was asked after one about whether they favored or opposed allowing gays and lesbians to marry (45% favored legal agreements when asked after the marriage question, but 37% favored legal agreements without the immediate preceding context of a question about same-sex marriage). Responses to the question about same-sex marriage, meanwhile, were not significantly affected by its placement before or after the legal agreements question.

Another experiment embedded in a December 2008 Pew Research Center poll also resulted in a contrast effect. When people were asked “All in all, are you satisfied or dissatisfied with the way things are going in this country today?” immediately after having been asked “Do you approve or disapprove of the way George W. Bush is handling his job as president?”; 88% said they were dissatisfied, compared with only 78% without the context of the prior question.

Responses to presidential approval remained relatively unchanged whether national satisfaction was asked before or after it. A similar finding occurred in December 2004 when both satisfaction and presidential approval were much higher (57% were dissatisfied when Bush approval was asked first vs. 51% when general satisfaction was asked first).

Several studies also have shown that asking a more specific question before a more general question (e.g., asking about happiness with one’s marriage before asking about one’s overall happiness) can result in a contrast effect. Although some exceptions have been found, people tend to avoid redundancy by excluding the more specific question from the general rating.

Assimilation effects occur when responses to two questions are more consistent or closer together because of their placement in the questionnaire. We found an example of an assimilation effect in a Pew Research Center poll conducted in November 2008 when we asked whether Republican leaders should work with Obama or stand up to him on important issues and whether Democratic leaders should work with Republican leaders or stand up to them on important issues. People were more likely to say that Republican leaders should work with Obama when the question was preceded by the one asking what Democratic leaders should do in working with Republican leaders (81% vs. 66%). However, when people were first asked about Republican leaders working with Obama, fewer said that Democratic leaders should work with Republican leaders (71% vs. 82%).

The order questions are asked is of particular importance when tracking trends over time. As a result, care should be taken to ensure that the context is similar each time a question is asked. Modifying the context of the question could call into question any observed changes over time (see measuring change over time for more information).

A questionnaire, like a conversation, should be grouped by topic and unfold in a logical order. It is often helpful to begin the survey with simple questions that respondents will find interesting and engaging. Throughout the survey, an effort should be made to keep the survey interesting and not overburden respondents with several difficult questions right after one another. Demographic questions such as income, education or age should not be asked near the beginning of a survey unless they are needed to determine eligibility for the survey or for routing respondents through particular sections of the questionnaire. Even then, it is best to precede such items with more interesting and engaging questions. One virtue of survey panels like the ATP is that demographic questions usually only need to be asked once a year, not in each survey.

Undergraduate Spearheads Study Using Physics to Understand How Cells Self-Sort

two people standing in front of research poster

Physics alumna Erin McCarthy ’23, right, was lead author on a study published in Physical Review Letters, which uncovered mechanisms that cause particles to sort spontaneously into different groups. Professor M. Lisa Manning, left, was a co-author.

Erin McCarthy ’23, physics summa cum laude, is a rarity among young scientists. As an undergraduate researcher in the College of Arts and Sciences’ Department of Physics , she guided a study that appeared in March 2024 in Physical Review Letters . It is the most-cited physics letters journal and the eighth-most cited journal in science overall.

McCarthy and postdoctoral associates Raj Kumar Manna and Ojan Damavandi developed a model that identified an unexpected collective behavior among computational particles with implications for future basic medical research and bioengineering.

“It’s very difficult to get a paper into Physical Review Letters,” says M. Lisa Manning , co-author and the William R. Kenan, Jr. Professor of Physics, as well as founding director of the BioInspired Institute . “Your scientific peers must judge it as exceptional.”

McCarthy, a New Jersey native, chose Syracuse because of its “tremendous energy,” she says. “The educational and the research side of things was amazing. I came planning to be a physics major who was premed. I loved physics and biology, and I wanted to be involved in healthcare and medicine. And I got lucky in that I met Dr. Manning as a freshman, and she introduced me to computational biophysics. I started in research during my freshman year, which is extremely unusual.”

“Erin learned coding from scratch, and then did hours and hours of simulations, which took a lot of perseverance,” says Manning. “It’s just a fantastic testament to her work ethic and brilliance that this paper appeared in such a prestigious journal.”

The research team used computational physics modeling to figure out the underlying mechanisms that cause particles to sort spontaneously into different groups.

Learning how particles behave in physics models could provide insight into how living biological particles—cells, proteins and enzymes—remix themselves in development.

In the early stages of an embryo, for example, cells start out in heterogeneous mixtures. Cells must self-sort into different compartments to form distinct homogenous tissues. This is one of the major collective cell behaviors at work during development of tissues and organs and organ regeneration.

“Cells need to be able to organize themselves properly, segregating themselves to do their jobs,” says McCarthy. “We wanted to understand, if you remove chemistry and look strictly at physics, what are the mechanisms by which this reorganization can happen spontaneously?”

Previous physics investigations found that particles separate when some receive a jolt of higher temperature. As one population of particles becomes injected with energy at a small scale, it turns active—or “hot”—while the other population is left inactive, or “cold.” This difference in heat causes a reorganization among the two populations. These models are simplified versions of biological systems, using temperature to approximate cellular energy and movement.

“Hot particles push the cold particles aside so they can take over a larger space,” says co-author Manna. “But that only happens when a gap exists between particles.”

Previous modeling identified self-sorting particle behavior at less-packed, intermediate densities.

But the Syracuse team found something surprising. After injecting energy into a population of high-density particles, the hot particles did not shove cold ones around. The hot particles lacked space to do so.

That is important because biological particles—proteins in cells and cells in tissue—typically live in tight, crowded spaces.

“Your skin, for instance, is a very dense environment,” says McCarthy. “Cells are packed so closely together, there’s no space between them. If we want to apply these physics findings to biology, we must look at high densities for our models to be applicable. But at very high densities, the difference in activity between two populations does not cause them to sort.”

There must be some other self-sorting mechanism at play in biology. “Temperature or active injection of energy does not always separate things, so you can’t use it in biology,” says Manning. “You must search for some other mechanism.”

To Manning, this study illustrates the strengths of Syracuse University. “The fact that an undergraduate spearheaded this research speaks to the awesome quality of students we have at Syracuse University, who are as good as those anywhere in the world, and to the exceptionalness of Erin herself,” says Manning.

Manna, the postdoctoral mentor for the last part of McCarthy’s project, was essential in driving it to conclusion.

“The study wouldn’t have happened without him,” says Manning. “This demonstrates that we are able to recruit outstanding postdoctoral associates to Syracuse because we are such a great research university.” Manna is now a postdoctoral fellow in the Department of Physics at Northeastern University.

McCarthy, a research technologist in a biological lab at the Northwestern University School of Medicine, plans to start applying for graduate school.

“At Syracuse,” says McCarthy, “I learned how much I love research and want it to be a part of my future.”
