Research Paper

Definition:

Research Paper is a written document that presents the author’s original research, analysis, and interpretation of a specific topic or issue.

It is typically based on Empirical Evidence, and may involve qualitative or quantitative research methods, or a combination of both. The purpose of a research paper is to contribute new knowledge or insights to a particular field of study, and to demonstrate the author’s understanding of the existing literature and theories related to the topic.

Structure of Research Paper

The structure of a research paper typically follows a standard format, consisting of several sections that convey specific information about the research study. The following is a detailed explanation of the structure of a research paper:

The title page contains the title of the paper, the name(s) of the author(s), and the affiliation(s) of the author(s). It also includes the date of submission and possibly, the name of the journal or conference where the paper is to be published.

The abstract is a brief summary of the research paper, typically ranging from 100 to 250 words. It should include the research question, the methods used, the key findings, and the implications of the results. The abstract should be written in a concise and clear manner to allow readers to quickly grasp the essence of the research.

Introduction

The introduction section of a research paper provides background information about the research problem, the research question, and the research objectives. It also outlines the significance of the research, the research gap that it aims to fill, and the approach taken to address the research question. Finally, the introduction section ends with a clear statement of the research hypothesis or research question.

Literature Review

The literature review section of a research paper provides an overview of the existing literature on the topic of study. It includes a critical analysis and synthesis of the literature, highlighting the key concepts, themes, and debates. The literature review should also demonstrate the research gap and how the current study seeks to address it.

The methods section of a research paper describes the research design, the sample selection, the data collection and analysis procedures, and the statistical methods used to analyze the data. This section should provide sufficient detail for other researchers to replicate the study.

The results section presents the findings of the research, using tables, graphs, and figures to illustrate the data. The findings should be presented in a clear and concise manner, with reference to the research question and hypothesis.

The discussion section of a research paper interprets the findings and discusses their implications for the research question, the literature review, and the field of study. It should also address the limitations of the study and suggest future research directions.

The conclusion section summarizes the main findings of the study, restates the research question and hypothesis, and provides a final reflection on the significance of the research.

The references section provides a list of all the sources cited in the paper, following a specific citation style such as APA, MLA or Chicago.

How to Write Research Paper

You can write Research Paper by the following guide:

• Choose a Topic: The first step is to select a topic that interests you and is relevant to your field of study. Brainstorm ideas and narrow down to a research question that is specific and researchable.

Title: The Impact of Social Media on Mental Health among Young Adults

Abstract: This study aims to investigate the impact of social media use on the mental health of young adults. A literature review was conducted to examine the existing research on the topic. A survey was then administered to 200 university students to collect data on their social media use, mental health status, and perceived impact of social media on their mental health. The results showed that social media use is positively associated with depression, anxiety, and stress. The study also found that social comparison, cyberbullying, and FOMO (Fear of Missing Out) are significant predictors of mental health problems among young adults.

Introduction: Social media has become an integral part of modern life, particularly among young adults. While social media has many benefits, including increased communication and social connectivity, it has also been associated with negative outcomes, such as addiction, cyberbullying, and mental health problems. This study aims to investigate the impact of social media use on the mental health of young adults.

Literature Review: The literature review highlights the existing research on the impact of social media use on mental health. The review shows that social media use is associated with depression, anxiety, stress, and other mental health problems. The review also identifies the factors that contribute to the negative impact of social media, including social comparison, cyberbullying, and FOMO.

Methods : A survey was administered to 200 university students to collect data on their social media use, mental health status, and perceived impact of social media on their mental health. The survey included questions on social media use, mental health status (measured using the DASS-21), and perceived impact of social media on their mental health. Data were analyzed using descriptive statistics and regression analysis.

Results : The results showed that social media use is positively associated with depression, anxiety, and stress. The study also found that social comparison, cyberbullying, and FOMO are significant predictors of mental health problems among young adults.

Discussion : The study’s findings suggest that social media use has a negative impact on the mental health of young adults. The study highlights the need for interventions that address the factors contributing to the negative impact of social media, such as social comparison, cyberbullying, and FOMO.

Conclusion : In conclusion, social media use has a significant impact on the mental health of young adults. The study’s findings underscore the need for interventions that promote healthy social media use and address the negative outcomes associated with social media use. Future research can explore the effectiveness of interventions aimed at reducing the negative impact of social media on mental health. Additionally, longitudinal studies can investigate the long-term effects of social media use on mental health.

Limitations : The study has some limitations, including the use of self-report measures and a cross-sectional design. The use of self-report measures may result in biased responses, and a cross-sectional design limits the ability to establish causality.

Implications: The study’s findings have implications for mental health professionals, educators, and policymakers. Mental health professionals can use the findings to develop interventions that address the negative impact of social media use on mental health. Educators can incorporate social media literacy into their curriculum to promote healthy social media use among young adults. Policymakers can use the findings to develop policies that protect young adults from the negative outcomes associated with social media use.

Research findings can be used to inform the development of policies, guidelines, and best practices that can improve outcomes for individuals and organizations.
• To share new insights or ideas: Researchers may write research papers to share new insights or ideas with the academic or professional community. They may present new theories, propose new research methods, or challenge existing paradigms in their field.

Purpose of Research Paper

The purpose of a research paper is to present the results of a study or investigation in a clear, concise, and structured manner. Research papers are written to communicate new knowledge, ideas, or findings to a specific audience, such as researchers, scholars, practitioners, or policymakers. The primary purposes of a research paper are:

• To contribute to the body of knowledge : Research papers aim to add new knowledge or insights to a particular field or discipline. They do this by reporting the results of empirical studies, reviewing and synthesizing existing literature, proposing new theories, or providing new perspectives on a topic.
• To inform or persuade: Research papers are written to inform or persuade the reader about a particular issue, topic, or phenomenon. They present evidence and arguments to support their claims and seek to persuade the reader of the validity of their findings or recommendations.
• To advance the field: Research papers seek to advance the field or discipline by identifying gaps in knowledge, proposing new research questions or approaches, or challenging existing assumptions or paradigms. They aim to contribute to ongoing debates and discussions within a field and to stimulate further research and inquiry.

Guidelines for Writing your Research Application Essay

The following are guidelines for writing your  Research Scholarship  application essay. These ideas will help you to think about how to structure your essay and what to include in it. They are not meant to be step-by-step instructions, nor are they given in any particular order of importance. If there is anything unusual about your timeline, project, or circumstances, please talk about this as well. In addition to reviewing these tips, you may wish to attend an  information session  before writing your essay.

Write in your own voice

Write your essay in your own voice.

It is very important that reviewers get a sense of your passion and understanding for your project. Do not cut and paste from papers or other proposals – it will be obvious to reviewers if you do and it will not convey your own understanding of your research. Write clearly and in your own voice describing your project and its relationship to research in your field of study.

Balance your essay

Be sure to talk about the project itself as well as the educational benefits of the research. As you are writing the personal side of the essay it may help in your draft to tell the story of your motivations for getting involved. But in your final essay, pull out only those points that are relevant to your current experience.

Show your enthusiasm and commitment to the work

Your essay should convey an interest and commitment to the research. Awards cover either a six or nine month period – be sure that your essay provides evidence that you will stick with the project for that period of time, and that the project has enough depth to keep you engaged during that period. Reviewers will find your interest or passion in the research compelling, so find a way to convey that in your essay.

For previous applicants/recipients

Acknowledge your prior application/award and cite the major learning goals you will set for yourself with this new application. Reviewers will want to know what you have already accomplished, as well as your plans for the new award period.

Be clear about your role in research

Be specific about your role in your proposed research project.

It is important that reviewers learn how you are contributing to the research, particularly if you have a role in a larger, ongoing project.

Describe how your faculty mentor guides/supports your role in the research process

If your research is of your own design, be sure to include how your faculty mentor helps you to make progress in your work. How does your mentor guide you so that you gain the perspective of the larger project as you contribute your work to it?

Describe the impact of your research

Describe how your research fits into a bigger picture.

Include enough detail to convey your knowledge of the topic and so that reviewers can imagine what you are doing. Reviewers will be from a variety of fields, so it is best to address your essay to an intelligent non-expert. Define field-specific terminology and be sure to give the big picture of your research area. It will also be important to include enough detail that someone in your discipline will have confidence that you understand the field in which you are working well enough to be able to contribute to the project in a meaningful way.

Describe what challenges you currently face, and how this award will help you take the next steps in your education

Be sure to describe your role in the research, and how it may have changed since your prior award. What new challenges do you need to overcome to take your work to a higher level? Will you be taking on additional responsibilities? If you are starting a whole new project and/or working with a new mentor, you may want to address the reason for the change, how the new experience will provide new opportunity for learning, and how your new mentor will contribute to that learning.

Talk about the impact of the research experience on your education

One of the goals of the Mary Gates Endowment is to invest in scholarships that help students to achieve their educational goals. Your essay should describe how the research will help you to further your own goals, and how it may help you address any difficulties you face in achieving those goals.

Follow the provided instructions on formatting, citations, etc.

Adhere to general formatting guidelines provided for the application.

Essays should be a maximum of four pages . Do not exceed the maximum page count or your application may not be considered.  Essays should be double-spaced, in 12-point font or equivalent size with standard margins. You may include one additional page for references, images, or figures, if applicable; this one additional page of supplementary material is not included in the page limit.

Properly cite the figures, graphs, and/or images that you refer to in your essay

If you refer to a figure, graph or image in your essay that is not your own, be sure to credit the source. Essays with figures, graphs or images lacking proper citations will be marked down by reviewers. Information on proper citation format can be found at:

• UW Libraries Citations Guide
• Odegaard Writing Research Center Resources

Please refrain from citing excessive sources not relevant to your project.

Ask for critical feedback before submitting your application

Ask your faculty research mentor and someone who is not involved with the research to review your essay.

Your mentor will provide you with the best feedback on your essay’s representation of the research you are doing and how it fits into a larger framework. Someone else – a peer, another instructor, or adviser – will be able to tell you if your essay is clear to an intelligent non-expert, and if you have conveyed a sense of enthusiasm and commitment for the work you describe. Be sure to leave yourself enough time to get feedback from these key people before submitting your application.

Schedule an advising appointment with us

If you would like to discuss your application/proposed research project with a Mary Gates team member before submitting, we highly encourage you to schedule an advising appointment with us. For first-time applicants, we recommend that you schedule a ‘First-time Applicant Advising Appointment” or a “General Advising Appointment’. For returning applicants/awardees, you are able to discuss your past applications with an MGE team member by scheduling a ‘Feedback Appointment’ with us.

Attend an application workshop

During each application cycle, we host application workshops that applicants are encouraged to attend. These workshops will give applicants more in-depth advice on how to structure their application essay and what to include. Applicants are asked to bring a draft of their application to the workshop as well, as there is allotted time for peer reviews and for applicants to ask specific questions pertaining to their project/application. RSVP here for our application workshops !

Information for previous applicants

We expect that previous awardees have a deeper than average understanding of their research, are working at a high level, and can clearly articulate previous accomplishments as well as opportunities for new learning and achievements during a second award period.  We also expect a strong connection between the research and a student’s longer-term goals.

How to write your first research paper.

Writing a research manuscript is an intimidating process for many novice writers in the sciences. One of the stumbling blocks is the beginning of the process and creating the first draft. This paper presents guidelines on how to initiate the writing process and draft each section of a research manuscript. The paper discusses seven rules that allow the writer to prepare a well-structured and comprehensive manuscript for a publication submission. In addition, the author lists different strategies for successful revision. Each of those strategies represents a step in the revision process and should help the writer improve the quality of the manuscript. The paper could be considered a brief manual for publication.

It is late at night. You have been struggling with your project for a year. You generated an enormous amount of interesting data. Your pipette feels like an extension of your hand, and running western blots has become part of your daily routine, similar to brushing your teeth. Your colleagues think you are ready to write a paper, and your lab mates tease you about your “slow” writing progress. Yet days pass, and you cannot force yourself to sit down to write. You have not written anything for a while (lab reports do not count), and you feel you have lost your stamina. How does the writing process work? How can you fit your writing into a daily schedule packed with experiments? What section should you start with? What distinguishes a good research paper from a bad one? How should you revise your paper? These and many other questions buzz in your head and keep you stressed. As a result, you procrastinate. In this paper, I will discuss the issues related to the writing process of a scientific paper. Specifically, I will focus on the best approaches to start a scientific paper, tips for writing each section, and the best revision strategies.

1. Schedule your writing time in Outlook

Whether you have written 100 papers or you are struggling with your first, starting the process is the most difficult part unless you have a rigid writing schedule. Writing is hard. It is a very difficult process of intense concentration and brain work. As stated in Hayes’ framework for the study of writing: “It is a generative activity requiring motivation, and it is an intellectual activity requiring cognitive processes and memory” [ 1 ]. In his book How to Write a Lot: A Practical Guide to Productive Academic Writing , Paul Silvia says that for some, “it’s easier to embalm the dead than to write an article about it” [ 2 ]. Just as with any type of hard work, you will not succeed unless you practice regularly. If you have not done physical exercises for a year, only regular workouts can get you into good shape again. The same kind of regular exercises, or I call them “writing sessions,” are required to be a productive author. Choose from 1- to 2-hour blocks in your daily work schedule and consider them as non-cancellable appointments. When figuring out which blocks of time will be set for writing, you should select the time that works best for this type of work. For many people, mornings are more productive. One Yale University graduate student spent a semester writing from 8 a.m. to 9 a.m. when her lab was empty. At the end of the semester, she was amazed at how much she accomplished without even interrupting her regular lab hours. In addition, doing the hardest task first thing in the morning contributes to the sense of accomplishment during the rest of the day. This positive feeling spills over into our work and life and has a very positive effect on our overall attitude.

Rule 1: Create regular time blocks for writing as appointments in your calendar and keep these appointments.

2. start with an outline.

Now that you have scheduled time, you need to decide how to start writing. The best strategy is to start with an outline. This will not be an outline that you are used to, with Roman numerals for each section and neat parallel listing of topic sentences and supporting points. This outline will be similar to a template for your paper. Initially, the outline will form a structure for your paper; it will help generate ideas and formulate hypotheses. Following the advice of George M. Whitesides, “. . . start with a blank piece of paper, and write down, in any order, all important ideas that occur to you concerning the paper” [ 3 ]. Use Table 1 as a starting point for your outline. Include your visuals (figures, tables, formulas, equations, and algorithms), and list your findings. These will constitute the first level of your outline, which will eventually expand as you elaborate.

The next stage is to add context and structure. Here you will group all your ideas into sections: Introduction, Methods, Results, and Discussion/Conclusion ( Table 2 ). This step will help add coherence to your work and sift your ideas.

Now that you have expanded your outline, you are ready for the next step: discussing the ideas for your paper with your colleagues and mentor. Many universities have a writing center where graduate students can schedule individual consultations and receive assistance with their paper drafts. Getting feedback during early stages of your draft can save a lot of time. Talking through ideas allows people to conceptualize and organize thoughts to find their direction without wasting time on unnecessary writing. Outlining is the most effective way of communicating your ideas and exchanging thoughts. Moreover, it is also the best stage to decide to which publication you will submit the paper. Many people come up with three choices and discuss them with their mentors and colleagues. Having a list of journal priorities can help you quickly resubmit your paper if your paper is rejected.

Rule 2: Create a detailed outline and discuss it with your mentor and peers.

3. continue with drafts.

After you get enough feedback and decide on the journal you will submit to, the process of real writing begins. Copy your outline into a separate file and expand on each of the points, adding data and elaborating on the details. When you create the first draft, do not succumb to the temptation of editing. Do not slow down to choose a better word or better phrase; do not halt to improve your sentence structure. Pour your ideas into the paper and leave revision and editing for later. As Paul Silvia explains, “Revising while you generate text is like drinking decaffeinated coffee in the early morning: noble idea, wrong time” [ 2 ].

Many students complain that they are not productive writers because they experience writer’s block. Staring at an empty screen is frustrating, but your screen is not really empty: You have a template of your article, and all you need to do is fill in the blanks. Indeed, writer’s block is a logical fallacy for a scientist ― it is just an excuse to procrastinate. When scientists start writing a research paper, they already have their files with data, lab notes with materials and experimental designs, some visuals, and tables with results. All they need to do is scrutinize these pieces and put them together into a comprehensive paper.

3.1. Starting with Materials and Methods

If you still struggle with starting a paper, then write the Materials and Methods section first. Since you have all your notes, it should not be problematic for you to describe the experimental design and procedures. Your most important goal in this section is to be as explicit as possible by providing enough detail and references. In the end, the purpose of this section is to allow other researchers to evaluate and repeat your work. So do not run into the same problems as the writers of the sentences in (1):

1a. Bacteria were pelleted by centrifugation. 1b. To isolate T cells, lymph nodes were collected.

As you can see, crucial pieces of information are missing: the speed of centrifuging your bacteria, the time, and the temperature in (1a); the source of lymph nodes for collection in (b). The sentences can be improved when information is added, as in (2a) and (2b), respectfully:

2a. Bacteria were pelleted by centrifugation at 3000g for 15 min at 25°C. 2b. To isolate T cells, mediastinal and mesenteric lymph nodes from Balb/c mice were collected at day 7 after immunization with ovabumin.

If your method has previously been published and is well-known, then you should provide only the literature reference, as in (3a). If your method is unpublished, then you need to make sure you provide all essential details, as in (3b).

3a. Stem cells were isolated, according to Johnson [23]. 3b. Stem cells were isolated using biotinylated carbon nanotubes coated with anti-CD34 antibodies.

Furthermore, cohesion and fluency are crucial in this section. One of the malpractices resulting in disrupted fluency is switching from passive voice to active and vice versa within the same paragraph, as shown in (4). This switching misleads and distracts the reader.

4. Behavioral computer-based experiments of Study 1 were programmed by using E-Prime. We took ratings of enjoyment, mood, and arousal as the patients listened to preferred pleasant music and unpreferred music by using Visual Analogue Scales (SI Methods). The preferred and unpreferred status of the music was operationalized along a continuum of pleasantness [ 4 ].

The problem with (4) is that the reader has to switch from the point of view of the experiment (passive voice) to the point of view of the experimenter (active voice). This switch causes confusion about the performer of the actions in the first and the third sentences. To improve the coherence and fluency of the paragraph above, you should be consistent in choosing the point of view: first person “we” or passive voice [ 5 ]. Let’s consider two revised examples in (5).

5a. We programmed behavioral computer-based experiments of Study 1 by using E-Prime. We took ratings of enjoyment, mood, and arousal by using Visual Analogue Scales (SI Methods) as the patients listened to preferred pleasant music and unpreferred music. We operationalized the preferred and unpreferred status of the music along a continuum of pleasantness. 5b. Behavioral computer-based experiments of Study 1 were programmed by using E-Prime. Ratings of enjoyment, mood, and arousal were taken as the patients listened to preferred pleasant music and unpreferred music by using Visual Analogue Scales (SI Methods). The preferred and unpreferred status of the music was operationalized along a continuum of pleasantness.

If you choose the point of view of the experimenter, then you may end up with repetitive “we did this” sentences. For many readers, paragraphs with sentences all beginning with “we” may also sound disruptive. So if you choose active sentences, you need to keep the number of “we” subjects to a minimum and vary the beginnings of the sentences [ 6 ].

Interestingly, recent studies have reported that the Materials and Methods section is the only section in research papers in which passive voice predominantly overrides the use of the active voice [ 5 , 7 , 8 , 9 ]. For example, Martínez shows a significant drop in active voice use in the Methods sections based on the corpus of 1 million words of experimental full text research articles in the biological sciences [ 7 ]. According to the author, the active voice patterned with “we” is used only as a tool to reveal personal responsibility for the procedural decisions in designing and performing experimental work. This means that while all other sections of the research paper use active voice, passive voice is still the most predominant in Materials and Methods sections.

Writing Materials and Methods sections is a meticulous and time consuming task requiring extreme accuracy and clarity. This is why when you complete your draft, you should ask for as much feedback from your colleagues as possible. Numerous readers of this section will help you identify the missing links and improve the technical style of this section.

Rule 3: Be meticulous and accurate in describing the Materials and Methods. Do not change the point of view within one paragraph.

3.2. writing results section.

For many authors, writing the Results section is more intimidating than writing the Materials and Methods section . If people are interested in your paper, they are interested in your results. That is why it is vital to use all your writing skills to objectively present your key findings in an orderly and logical sequence using illustrative materials and text.

Your Results should be organized into different segments or subsections where each one presents the purpose of the experiment, your experimental approach, data including text and visuals (tables, figures, schematics, algorithms, and formulas), and data commentary. For most journals, your data commentary will include a meaningful summary of the data presented in the visuals and an explanation of the most significant findings. This data presentation should not repeat the data in the visuals, but rather highlight the most important points. In the “standard” research paper approach, your Results section should exclude data interpretation, leaving it for the Discussion section. However, interpretations gradually and secretly creep into research papers: “Reducing the data, generalizing from the data, and highlighting scientific cases are all highly interpretive processes. It should be clear by now that we do not let the data speak for themselves in research reports; in summarizing our results, we interpret them for the reader” [ 10 ]. As a result, many journals including the Journal of Experimental Medicine and the Journal of Clinical Investigation use joint Results/Discussion sections, where results are immediately followed by interpretations.

Another important aspect of this section is to create a comprehensive and supported argument or a well-researched case. This means that you should be selective in presenting data and choose only those experimental details that are essential for your reader to understand your findings. You might have conducted an experiment 20 times and collected numerous records, but this does not mean that you should present all those records in your paper. You need to distinguish your results from your data and be able to discard excessive experimental details that could distract and confuse the reader. However, creating a picture or an argument should not be confused with data manipulation or falsification, which is a willful distortion of data and results. If some of your findings contradict your ideas, you have to mention this and find a plausible explanation for the contradiction.

In addition, your text should not include irrelevant and peripheral information, including overview sentences, as in (6).

6. To show our results, we first introduce all components of experimental system and then describe the outcome of infections.

Indeed, wordiness convolutes your sentences and conceals your ideas from readers. One common source of wordiness is unnecessary intensifiers. Adverbial intensifiers such as “clearly,” “essential,” “quite,” “basically,” “rather,” “fairly,” “really,” and “virtually” not only add verbosity to your sentences, but also lower your results’ credibility. They appeal to the reader’s emotions but lower objectivity, as in the common examples in (7):

7a. Table 3 clearly shows that … 7b. It is obvious from figure 4 that …

Another source of wordiness is nominalizations, i.e., nouns derived from verbs and adjectives paired with weak verbs including “be,” “have,” “do,” “make,” “cause,” “provide,” and “get” and constructions such as “there is/are.”

8a. We tested the hypothesis that there is a disruption of membrane asymmetry. 8b. In this paper we provide an argument that stem cells repopulate injured organs.

In the sentences above, the abstract nominalizations “disruption” and “argument” do not contribute to the clarity of the sentences, but rather clutter them with useless vocabulary that distracts from the meaning. To improve your sentences, avoid unnecessary nominalizations and change passive verbs and constructions into active and direct sentences.

9a. We tested the hypothesis that the membrane asymmetry is disrupted. 9b. In this paper we argue that stem cells repopulate injured organs.

Your Results section is the heart of your paper, representing a year or more of your daily research. So lead your reader through your story by writing direct, concise, and clear sentences.

Rule 4: Be clear, concise, and objective in describing your Results.

3.3. now it is time for your introduction.

Now that you are almost half through drafting your research paper, it is time to update your outline. While describing your Methods and Results, many of you diverged from the original outline and re-focused your ideas. So before you move on to create your Introduction, re-read your Methods and Results sections and change your outline to match your research focus. The updated outline will help you review the general picture of your paper, the topic, the main idea, and the purpose, which are all important for writing your introduction.

The best way to structure your introduction is to follow the three-move approach shown in Table 3 .

Adapted from Swales and Feak [ 11 ].

The moves and information from your outline can help to create your Introduction efficiently and without missing steps. These moves are traffic signs that lead the reader through the road of your ideas. Each move plays an important role in your paper and should be presented with deep thought and care. When you establish the territory, you place your research in context and highlight the importance of your research topic. By finding the niche, you outline the scope of your research problem and enter the scientific dialogue. The final move, “occupying the niche,” is where you explain your research in a nutshell and highlight your paper’s significance. The three moves allow your readers to evaluate their interest in your paper and play a significant role in the paper review process, determining your paper reviewers.

Some academic writers assume that the reader “should follow the paper” to find the answers about your methodology and your findings. As a result, many novice writers do not present their experimental approach and the major findings, wrongly believing that the reader will locate the necessary information later while reading the subsequent sections [ 5 ]. However, this “suspense” approach is not appropriate for scientific writing. To interest the reader, scientific authors should be direct and straightforward and present informative one-sentence summaries of the results and the approach.

Another problem is that writers understate the significance of the Introduction. Many new researchers mistakenly think that all their readers understand the importance of the research question and omit this part. However, this assumption is faulty because the purpose of the section is not to evaluate the importance of the research question in general. The goal is to present the importance of your research contribution and your findings. Therefore, you should be explicit and clear in describing the benefit of the paper.

The Introduction should not be long. Indeed, for most journals, this is a very brief section of about 250 to 600 words, but it might be the most difficult section due to its importance.

Rule 5: Interest your reader in the Introduction section by signalling all its elements and stating the novelty of the work.

3.4. discussion of the results.

For many scientists, writing a Discussion section is as scary as starting a paper. Most of the fear comes from the variation in the section. Since every paper has its unique results and findings, the Discussion section differs in its length, shape, and structure. However, some general principles of writing this section still exist. Knowing these rules, or “moves,” can change your attitude about this section and help you create a comprehensive interpretation of your results.

The purpose of the Discussion section is to place your findings in the research context and “to explain the meaning of the findings and why they are important, without appearing arrogant, condescending, or patronizing” [ 11 ]. The structure of the first two moves is almost a mirror reflection of the one in the Introduction. In the Introduction, you zoom in from general to specific and from the background to your research question; in the Discussion section, you zoom out from the summary of your findings to the research context, as shown in Table 4 .

Adapted from Swales and Feak and Hess [ 11 , 12 ].

The biggest challenge for many writers is the opening paragraph of the Discussion section. Following the moves in Table 1 , the best choice is to start with the study’s major findings that provide the answer to the research question in your Introduction. The most common starting phrases are “Our findings demonstrate . . .,” or “In this study, we have shown that . . .,” or “Our results suggest . . .” In some cases, however, reminding the reader about the research question or even providing a brief context and then stating the answer would make more sense. This is important in those cases where the researcher presents a number of findings or where more than one research question was presented. Your summary of the study’s major findings should be followed by your presentation of the importance of these findings. One of the most frequent mistakes of the novice writer is to assume the importance of his findings. Even if the importance is clear to you, it may not be obvious to your reader. Digesting the findings and their importance to your reader is as crucial as stating your research question.

Another useful strategy is to be proactive in the first move by predicting and commenting on the alternative explanations of the results. Addressing potential doubts will save you from painful comments about the wrong interpretation of your results and will present you as a thoughtful and considerate researcher. Moreover, the evaluation of the alternative explanations might help you create a logical step to the next move of the discussion section: the research context.

The goal of the research context move is to show how your findings fit into the general picture of the current research and how you contribute to the existing knowledge on the topic. This is also the place to discuss any discrepancies and unexpected findings that may otherwise distort the general picture of your paper. Moreover, outlining the scope of your research by showing the limitations, weaknesses, and assumptions is essential and adds modesty to your image as a scientist. However, make sure that you do not end your paper with the problems that override your findings. Try to suggest feasible explanations and solutions.

If your submission does not require a separate Conclusion section, then adding another paragraph about the “take-home message” is a must. This should be a general statement reiterating your answer to the research question and adding its scientific implications, practical application, or advice.

Just as in all other sections of your paper, the clear and precise language and concise comprehensive sentences are vital. However, in addition to that, your writing should convey confidence and authority. The easiest way to illustrate your tone is to use the active voice and the first person pronouns. Accompanied by clarity and succinctness, these tools are the best to convince your readers of your point and your ideas.

Rule 6: Present the principles, relationships, and generalizations in a concise and convincing tone.

4. choosing the best working revision strategies.

Now that you have created the first draft, your attitude toward your writing should have improved. Moreover, you should feel more confident that you are able to accomplish your project and submit your paper within a reasonable timeframe. You also have worked out your writing schedule and followed it precisely. Do not stop ― you are only at the midpoint from your destination. Just as the best and most precious diamond is no more than an unattractive stone recognized only by trained professionals, your ideas and your results may go unnoticed if they are not polished and brushed. Despite your attempts to present your ideas in a logical and comprehensive way, first drafts are frequently a mess. Use the advice of Paul Silvia: “Your first drafts should sound like they were hastily translated from Icelandic by a non-native speaker” [ 2 ]. The degree of your success will depend on how you are able to revise and edit your paper.

The revision can be done at the macrostructure and the microstructure levels [ 13 ]. The macrostructure revision includes the revision of the organization, content, and flow. The microstructure level includes individual words, sentence structure, grammar, punctuation, and spelling.

The best way to approach the macrostructure revision is through the outline of the ideas in your paper. The last time you updated your outline was before writing the Introduction and the Discussion. Now that you have the beginning and the conclusion, you can take a bird’s-eye view of the whole paper. The outline will allow you to see if the ideas of your paper are coherently structured, if your results are logically built, and if the discussion is linked to the research question in the Introduction. You will be able to see if something is missing in any of the sections or if you need to rearrange your information to make your point.

The next step is to revise each of the sections starting from the beginning. Ideally, you should limit yourself to working on small sections of about five pages at a time [ 14 ]. After these short sections, your eyes get used to your writing and your efficiency in spotting problems decreases. When reading for content and organization, you should control your urge to edit your paper for sentence structure and grammar and focus only on the flow of your ideas and logic of your presentation. Experienced researchers tend to make almost three times the number of changes to meaning than novice writers [ 15 , 16 ]. Revising is a difficult but useful skill, which academic writers obtain with years of practice.

In contrast to the macrostructure revision, which is a linear process and is done usually through a detailed outline and by sections, microstructure revision is a non-linear process. While the goal of the macrostructure revision is to analyze your ideas and their logic, the goal of the microstructure editing is to scrutinize the form of your ideas: your paragraphs, sentences, and words. You do not need and are not recommended to follow the order of the paper to perform this type of revision. You can start from the end or from different sections. You can even revise by reading sentences backward, sentence by sentence and word by word.

One of the microstructure revision strategies frequently used during writing center consultations is to read the paper aloud [ 17 ]. You may read aloud to yourself, to a tape recorder, or to a colleague or friend. When reading and listening to your paper, you are more likely to notice the places where the fluency is disrupted and where you stumble because of a very long and unclear sentence or a wrong connector.

Another revision strategy is to learn your common errors and to do a targeted search for them [ 13 ]. All writers have a set of problems that are specific to them, i.e., their writing idiosyncrasies. Remembering these problems is as important for an academic writer as remembering your friends’ birthdays. Create a list of these idiosyncrasies and run a search for these problems using your word processor. If your problem is demonstrative pronouns without summary words, then search for “this/these/those” in your text and check if you used the word appropriately. If you have a problem with intensifiers, then search for “really” or “very” and delete them from the text. The same targeted search can be done to eliminate wordiness. Searching for “there is/are” or “and” can help you avoid the bulky sentences.

The final strategy is working with a hard copy and a pencil. Print a double space copy with font size 14 and re-read your paper in several steps. Try reading your paper line by line with the rest of the text covered with a piece of paper. When you are forced to see only a small portion of your writing, you are less likely to get distracted and are more likely to notice problems. You will end up spotting more unnecessary words, wrongly worded phrases, or unparallel constructions.

After you apply all these strategies, you are ready to share your writing with your friends, colleagues, and a writing advisor in the writing center. Get as much feedback as you can, especially from non-specialists in your field. Patiently listen to what others say to you ― you are not expected to defend your writing or explain what you wanted to say. You may decide what you want to change and how after you receive the feedback and sort it in your head. Even though some researchers make the revision an endless process and can hardly stop after a 14th draft; having from five to seven drafts of your paper is a norm in the sciences. If you can’t stop revising, then set a deadline for yourself and stick to it. Deadlines always help.

Rule 7: Revise your paper at the macrostructure and the microstructure level using different strategies and techniques. Receive feedback and revise again.

5. it is time to submit.

It is late at night again. You are still in your lab finishing revisions and getting ready to submit your paper. You feel happy ― you have finally finished a year’s worth of work. You will submit your paper tomorrow, and regardless of the outcome, you know that you can do it. If one journal does not take your paper, you will take advantage of the feedback and resubmit again. You will have a publication, and this is the most important achievement.

What is even more important is that you have your scheduled writing time that you are going to keep for your future publications, for reading and taking notes, for writing grants, and for reviewing papers. You are not going to lose stamina this time, and you will become a productive scientist. But for now, let’s celebrate the end of the paper.

Application Essays

What this handout is about.

This handout will help you write and revise the personal statement required by many graduate programs, internships, and special academic programs.

Before you start writing

Because the application essay can have a critical effect upon your progress toward a career, you should spend significantly more time, thought, and effort on it than its typically brief length would suggest. It should reflect how you arrived at your professional goals, why the program is ideal for you, and what you bring to the program. Don’t make this a deadline task—now’s the time to write, read, rewrite, give to a reader, revise again, and on until the essay is clear, concise, and compelling. At the same time, don’t be afraid. You know most of the things you need to say already.

Read the instructions carefully. One of the basic tasks of the application essay is to follow the directions. If you don’t do what they ask, the reader may wonder if you will be able to follow directions in their program. Make sure you follow page and word limits exactly—err on the side of shortness, not length. The essay may take two forms:

• A one-page essay answering a general question
• Several short answers to more specific questions

Do some research before you start writing. Think about…

• The field. Why do you want to be a _____? No, really. Think about why you and you particularly want to enter that field. What are the benefits and what are the shortcomings? When did you become interested in the field and why? What path in that career interests you right now? Brainstorm and write these ideas out.
• The program. Why is this the program you want to be admitted to? What is special about the faculty, the courses offered, the placement record, the facilities you might be using? If you can’t think of anything particular, read the brochures they offer, go to events, or meet with a faculty member or student in the program. A word about honesty here—you may have a reason for choosing a program that wouldn’t necessarily sway your reader; for example, you want to live near the beach, or the program is the most prestigious and would look better on your resume. You don’t want to be completely straightforward in these cases and appear superficial, but skirting around them or lying can look even worse. Turn these aspects into positives. For example, you may want to go to a program in a particular location because it is a place that you know very well and have ties to, or because there is a need in your field there. Again, doing research on the program may reveal ways to legitimate even your most superficial and selfish reasons for applying.
• Yourself. What details or anecdotes would help your reader understand you? What makes you special? Is there something about your family, your education, your work/life experience, or your values that has shaped you and brought you to this career field? What motivates or interests you? Do you have special skills, like leadership, management, research, or communication? Why would the members of the program want to choose you over other applicants? Be honest with yourself and write down your ideas. If you are having trouble, ask a friend or relative to make a list of your strengths or unique qualities that you plan to read on your own (and not argue about immediately). Ask them to give you examples to back up their impressions (For example, if they say you are “caring,” ask them to describe an incident they remember in which they perceived you as caring).

Now, write a draft

This is a hard essay to write. It’s probably much more personal than any of the papers you have written for class because it’s about you, not World War II or planaria. You may want to start by just getting something—anything—on paper. Try freewriting. Think about the questions we asked above and the prompt for the essay, and then write for 15 or 30 minutes without stopping. What do you want your audience to know after reading your essay? What do you want them to feel? Don’t worry about grammar, punctuation, organization, or anything else. Just get out the ideas you have. For help getting started, see our handout on brainstorming .

Now, look at what you’ve written. Find the most relevant, memorable, concrete statements and focus in on them. Eliminate any generalizations or platitudes (“I’m a people person”, “Doctors save lives”, or “Mr. Calleson’s classes changed my life”), or anything that could be cut and pasted into anyone else’s application. Find what is specific to you about the ideas that generated those platitudes and express them more directly. Eliminate irrelevant issues (“I was a track star in high school, so I think I’ll make a good veterinarian.”) or issues that might be controversial for your reader (“My faith is the one true faith, and only nurses with that faith are worthwhile,” or “Lawyers who only care about money are evil.”).

Often, writers start out with generalizations as a way to get to the really meaningful statements, and that’s OK. Just make sure that you replace the generalizations with examples as you revise. A hint: you may find yourself writing a good, specific sentence right after a general, meaningless one. If you spot that, try to use the second sentence and delete the first.

Applications that have several short-answer essays require even more detail. Get straight to the point in every case, and address what they’ve asked you to address.

Now that you’ve generated some ideas, get a little bit pickier. It’s time to remember one of the most significant aspects of the application essay: your audience. Your readers may have thousands of essays to read, many or most of which will come from qualified applicants. This essay may be your best opportunity to communicate with the decision makers in the application process, and you don’t want to bore them, offend them, or make them feel you are wasting their time.

With this in mind:

• Do assure your audience that you understand and look forward to the challenges of the program and the field, not just the benefits.
• Do assure your audience that you understand exactly the nature of the work in the field and that you are prepared for it, psychologically and morally as well as educationally.
• Do assure your audience that you care about them and their time by writing a clear, organized, and concise essay.
• Do address any information about yourself and your application that needs to be explained (for example, weak grades or unusual coursework for your program). Include that information in your essay, and be straightforward about it. Your audience will be more impressed with your having learned from setbacks or having a unique approach than your failure to address those issues.
• Don’t waste space with information you have provided in the rest of the application. Every sentence should be effective and directly related to the rest of the essay. Don’t ramble or use fifteen words to express something you could say in eight.
• Don’t overstate your case for what you want to do, being so specific about your future goals that you come off as presumptuous or naïve (“I want to become a dentist so that I can train in wisdom tooth extraction, because I intend to focus my life’s work on taking 13 rather than 15 minutes per tooth.”). Your goals may change–show that such a change won’t devastate you.
• And, one more time, don’t write in cliches and platitudes. Every doctor wants to help save lives, every lawyer wants to work for justice—your reader has read these general cliches a million times.

Imagine the worst-case scenario (which may never come true—we’re talking hypothetically): the person who reads your essay has been in the field for decades. She is on the application committee because she has to be, and she’s read 48 essays so far that morning. You are number 49, and your reader is tired, bored, and thinking about lunch. How are you going to catch and keep her attention?

Assure your audience that you are capable academically, willing to stick to the program’s demands, and interesting to have around. For more tips, see our handout on audience .

Voice and style

The voice you use and the style in which you write can intrigue your audience. The voice you use in your essay should be yours. Remember when your high school English teacher said “never say ‘I’”? Here’s your chance to use all those “I”s you’ve been saving up. The narrative should reflect your perspective, experiences, thoughts, and emotions. Focusing on events or ideas may give your audience an indirect idea of how these things became important in forming your outlook, but many others have had equally compelling experiences. By simply talking about those events in your own voice, you put the emphasis on you rather than the event or idea. Look at this anecdote:

During the night shift at Wirth Memorial Hospital, a man walked into the Emergency Room wearing a monkey costume and holding his head. He seemed confused and was moaning in pain. One of the nurses ascertained that he had been swinging from tree branches in a local park and had hit his head when he fell out of a tree. This tragic tale signified the moment at which I realized psychiatry was the only career path I could take.

An interesting tale, yes, but what does it tell you about the narrator? The following example takes the same anecdote and recasts it to make the narrator more of a presence in the story:

I was working in the Emergency Room at Wirth Memorial Hospital one night when a man walked in wearing a monkey costume and holding his head. I could tell he was confused and in pain. After a nurse asked him a few questions, I listened in surprise as he explained that he had been a monkey all of his life and knew that it was time to live with his brothers in the trees. Like many other patients I would see that year, this man suffered from an illness that only a combination of psychological and medical care would effectively treat. I realized then that I wanted to be able to help people by using that particular combination of skills only a psychiatrist develops.

The voice you use should be approachable as well as intelligent. This essay is not the place to stun your reader with ten prepositional phrases (“the goal of my study of the field of law in the winter of my discontent can best be understood by the gathering of more information about my youth”) and thirty nouns (“the research and study of the motivation behind my insights into the field of dentistry contains many pitfalls and disappointments but even more joy and enlightenment”) per sentence. (Note: If you are having trouble forming clear sentences without all the prepositions and nouns, take a look at our handout on style .)

You may want to create an impression of expertise in the field by using specialized or technical language. But beware of this unless you really know what you are doing—a mistake will look twice as ignorant as not knowing the terms in the first place. Your audience may be smart, but you don’t want to make them turn to a dictionary or fall asleep between the first word and the period of your first sentence. Keep in mind that this is a personal statement. Would you think you were learning a lot about a person whose personal statement sounded like a journal article? Would you want to spend hours in a lab or on a committee with someone who shuns plain language?

Of course, you don’t want to be chatty to the point of making them think you only speak slang, either. Your audience may not know what “I kicked that lame-o to the curb for dissing my research project” means. Keep it casual enough to be easy to follow, but formal enough to be respectful of the audience’s intelligence.

Just use an honest voice and represent yourself as naturally as possible. It may help to think of the essay as a sort of face-to-face interview, only the interviewer isn’t actually present.

Too much style

A well-written, dramatic essay is much more memorable than one that fails to make an emotional impact on the reader. Good anecdotes and personal insights can really attract an audience’s attention. BUT be careful not to let your drama turn into melodrama. You want your reader to see your choices motivated by passion and drive, not hyperbole and a lack of reality. Don’t invent drama where there isn’t any, and don’t let the drama take over. Getting someone else to read your drafts can help you figure out when you’ve gone too far.

Taking risks

Many guides to writing application essays encourage you to take a risk, either by saying something off-beat or daring or by using a unique writing style. When done well, this strategy can work—your goal is to stand out from the rest of the applicants and taking a risk with your essay will help you do that. An essay that impresses your reader with your ability to think and express yourself in original ways and shows you really care about what you are saying is better than one that shows hesitancy, lack of imagination, or lack of interest.

But be warned: this strategy is a risk. If you don’t carefully consider what you are saying and how you are saying it, you may offend your readers or leave them with a bad impression of you as flaky, immature, or careless. Do not alienate your readers.

Some writers take risks by using irony (your suffering at the hands of a barbaric dentist led you to want to become a gentle one), beginning with a personal failure (that eventually leads to the writer’s overcoming it), or showing great imagination (one famous successful example involved a student who answered a prompt about past formative experiences by beginning with a basic answer—”I have volunteered at homeless shelters”—that evolved into a ridiculous one—”I have sealed the hole in the ozone layer with plastic wrap”). One student applying to an art program described the person he did not want to be, contrasting it with the person he thought he was and would develop into if accepted. Another person wrote an essay about her grandmother without directly linking her narrative to the fact that she was applying for medical school. Her essay was risky because it called on the reader to infer things about the student’s character and abilities from the story.

Assess your credentials and your likelihood of getting into the program before you choose to take a risk. If you have little chance of getting in, try something daring. If you are almost certainly guaranteed a spot, you have more flexibility. In any case, make sure that you answer the essay question in some identifiable way.

After you’ve written a draft

Get several people to read it and write their comments down. It is worthwhile to seek out someone in the field, perhaps a professor who has read such essays before. Give it to a friend, your mom, or a neighbor. The key is to get more than one point of view, and then compare these with your own. Remember, you are the one best equipped to judge how accurately you are representing yourself. For tips on putting this advice to good use, see our handout on getting feedback .

After you’ve received feedback, revise the essay. Put it away. Get it out and revise it again (you can see why we said to start right away—this process may take time). Get someone to read it again. Revise it again.

When you think it is totally finished, you are ready to proofread and format the essay. Check every sentence and punctuation mark. You cannot afford a careless error in this essay. (If you are not comfortable with your proofreading skills, check out our handout on editing and proofreading ).

If you find that your essay is too long, do not reformat it extensively to make it fit. Making readers deal with a nine-point font and quarter-inch margins will only irritate them. Figure out what material you can cut and cut it. For strategies for meeting word limits, see our handout on writing concisely .

Finally, proofread it again. We’re not kidding.

Other resources

Don’t be afraid to talk to professors or professionals in the field. Many of them would be flattered that you asked their advice, and they will have useful suggestions that others might not have. Also keep in mind that many colleges and professional programs offer websites addressing the personal statement. You can find them either through the website of the school to which you are applying or by searching under “personal statement” or “application essays” using a search engine.

If your schedule and ours permit, we invite you to come to the Writing Center. Be aware that during busy times in the semester, we limit students to a total of two visits to discuss application essays and personal statements (two visits per student, not per essay); we do this so that students working on papers for courses will have a better chance of being seen. Make an appointment or submit your essay to our online writing center (note that we cannot guarantee that an online tutor will help you in time).

For information on other aspects of the application process, you can consult the resources at University Career Services .

How to Create a Structured Research Paper Outline | Example

Published on August 7, 2022 by Courtney Gahan . Revised on August 15, 2023.

A research paper outline is a useful tool to aid in the writing process , providing a structure to follow with all information to be included in the paper clearly organized.

A quality outline can make writing your research paper more efficient by helping to:

• Organize your thoughts
• Understand the flow of information and how ideas are related
• Ensure nothing is forgotten

A research paper outline can also give your teacher an early idea of the final product.

• Definition of measles
• Rise in cases in recent years in places the disease was previously eliminated or had very low rates of infection
• Figures: Number of cases per year on average, number in recent years. Relate to immunization
• Symptoms and timeframes of disease
• Risk of fatality, including statistics
• How measles is spread
• Immunization procedures in different regions
• Different regions, focusing on the arguments from those against immunization
• Immunization figures in affected regions
• High number of cases in non-immunizing regions
• Illnesses that can result from measles virus
• Fatal cases of other illnesses after patient contracted measles
• Summary of arguments of different groups
• Summary of figures and relationship with recent immunization debate
• Which side of the argument appears to be correct?

Scribbr Citation Checker New

The AI-powered Citation Checker helps you avoid common mistakes such as:

• Missing commas and periods
• Incorrect usage of “et al.”
• Ampersands (&) in narrative citations
• Missing reference entries

Follow these steps to start your research paper outline:

• Decide on the subject of the paper
• Write down all the ideas you want to include or discuss
• Organize related ideas into sub-groups
• Arrange your ideas into a hierarchy: What should the reader learn first? What is most important? Which idea will help end your paper most effectively?
• Create headings and subheadings that are effective
• Format the outline in either alphanumeric, full-sentence or decimal format

There are three different kinds of research paper outline: alphanumeric, full-sentence and decimal outlines. The differences relate to formatting and style of writing.

• Alphanumeric
• Full-sentence

An alphanumeric outline is most commonly used. It uses Roman numerals, capitalized letters, arabic numerals, lowercase letters to organize the flow of information. Text is written with short notes rather than full sentences.

• Sub-point of sub-point 1

Essentially the same as the alphanumeric outline, but with the text written in full sentences rather than short points.

• Additional sub-point to conclude discussion of point of evidence introduced in point A

A decimal outline is similar in format to the alphanumeric outline, but with a different numbering system: 1, 1.1, 1.2, etc. Text is written as short notes rather than full sentences.

• 1.1.1 Sub-point of first point
• 1.1.2 Sub-point of first point
• 1.2 Second point

To write an effective research paper outline, it is important to pay attention to language. This is especially important if it is one you will show to your teacher or be assessed on.

There are four main considerations: parallelism, coordination, subordination and division.

Parallelism: Be consistent with grammatical form

Parallel structure or parallelism is the repetition of a particular grammatical form within a sentence, or in this case, between points and sub-points. This simply means that if the first point is a verb , the sub-point should also be a verb.

Example of parallelism:

• Include different regions, focusing on the different arguments from those against immunization

Coordination: Be aware of each point’s weight

Your chosen subheadings should hold the same significance as each other, as should all first sub-points, secondary sub-points, and so on.

Example of coordination:

• Include immunization figures in affected regions
• Illnesses that can result from the measles virus

Subordination: Work from general to specific

Subordination refers to the separation of general points from specific. Your main headings should be quite general, and each level of sub-point should become more specific.

Example of subordination:

Division: break information into sub-points.

Your headings should be divided into two or more subsections. There is no limit to how many subsections you can include under each heading, but keep in mind that the information will be structured into a paragraph during the writing stage, so you should not go overboard with the number of sub-points.

Second round of seed grants awarded to MIT scholars studying the impact and applications of generative AI

Press contact :.

Previous image Next image

Last summer, MIT President Sally Kornbluth and Provost Cynthia Barnhart issued a call for papers to “articulate effective roadmaps, policy recommendations, and calls for action across the broad domain of generative AI.” The response to the call far exceeded expectations with 75 proposals submitted. Of those, 27 proposals were selected for seed funding .

In light of this enthusiastic response, Kornbluth and Barnhart announced a second call for proposals this fall.

“The groundswell of interest and the caliber of the ideas overall made clear that a second round was in order,” they said in their email to MIT’s research community this fall. This second call for proposals resulted in 53 submissions.

Following the second call, the faculty committee from the first round considered the proposals and selected 16 proposals to receive exploratory funding. Co-authored by interdisciplinary teams of faculty and researchers affiliated with all five of the Institute’s schools and the MIT Schwarzman College of Computing, the proposals offer insights and perspectives on the potential impact and applications of generative AI across a broad range of topics and disciplines.

Each selected research group will receive between $50,000 and $70,000 to create 10-page impact papers. Those papers will be shared widely via a publication venue managed and hosted by the MIT Press under the auspices of the MIT Open Publishing Services program.

As with the first round of papers, Thomas Tull, a member of the MIT School of Engineering Dean’s Advisory Council and a former innovation scholar at the School of Engineering, contributed funding to support the effort.

The selected papers are:

• “A Road-map for End-to-end Privacy and Verifiability in Generative AI,” led by Alex Pentland, Srini Devadas, Lalana Kagal, and Vinod Vaikuntanathan;

Application Flows

We build and analyze a new U.S. database that links 125 million applications to job vacancies and employer-side clients on Dice.com, an online platform for jobs and workers in software design, computer systems, engineering, financial analysis, management consulting, and other occupations that require technical skills. We find, first, that posting durations are quite short, often only two or three days, with a median of seven days. Second, labor market tightness has tiny effects on posting durations. Third, job seekers display a striking propensity to target new postings, with almost half of applications flowing to openings posted in the past 48 hours. Fourth, applications per posting are much too uneven to reflect random search, even within narrow market segments and job categories. Moreover, posted offer wages play no role in explaining the deviations from a random-search benchmark. Fifth, intermediaries play a huge role on both sides of the platform: Recruitment and staffing firms account for two-thirds of all postings and attract most of the applications. We relate these and other findings to theories of labor market search.

Title: coverage-guaranteed prediction sets for out-of-distribution data.

Abstract: Out-of-distribution (OOD) generalization has attracted increasing research attention in recent years, due to its promising experimental results in real-world applications. In this paper,we study the confidence set prediction problem in the OOD generalization setting. Split conformal prediction (SCP) is an efficient framework for handling the confidence set prediction problem. However, the validity of SCP requires the examples to be exchangeable, which is violated in the OOD setting. Empirically, we show that trivially applying SCP results in a failure to maintain the marginal coverage when the unseen target domain is different from the source domain. To address this issue, we develop a method for forming confident prediction sets in the OOD setting and theoretically prove the validity of our method. Finally, we conduct experiments on simulated data to empirically verify the correctness of our theory and the validity of our proposed method.

Minneapolis, Minnesota

Last May, a team led by physicists at the University of Washington in Seattle observed something peculiar. When the scientists ran an electrical current across two atom-thin sheets of molybdenum ditelluride (MoTe 2 ), the electrons acted in concert, like particles with fractional charges. Resistance measurements showed that, rather than the usual charge of –1, the electrons behaved similar to particles with charges of –2/3 or –3/5, for instance. What was truly odd was that the electrons did this entirely because of the innate properties of the material, without any external magnetic field coaxing them. The researchers published the results a few months later, in August 1 .

Strange topological materials are popping up everywhere physicists look

The same month, this phenomenon, known as the fractional quantum anomalous Hall effect (FQAHE), was also observed in a completely different material. Researchers led by Long Ju, a condensed-matter physicist at the Massachusetts Institute of Technology (MIT) in Cambridge, saw the effect when they sandwiched five layers of graphene between sheets of boron nitride. They published their results in February this year 2 — and physicists are still buzzing about it.

At the American Physical Society (APS) March Meeting, held in Minneapolis, Minnesota, from 3 to 8 March, Ju presented the team’s findings, which haven’t yet been replicated by other researchers. Attendees, including Raquel Queiroz, a theoretical physicist at Columbia University in New York City, said that they thought the results were convincing, but were scratching their heads over the discovery. “There is a lot we don’t understand,” Queiroz says. Figuring out the exact mechanism of the FQAHE in the layered graphene will be “a lot of work ahead of theorists”, she adds.

Although the FQAHE might have practical applications down the line — fractionally charged particles are a key requirement for a certain type of quantum computer — the findings are capturing physicists’ imagination because they are fundamentally new discoveries about how electrons behave.

“I don’t know anyone who’s not excited about this,” says Pablo Jarillo-Herrero, a condensed-matter physicist at MIT who was not involved with the studies. “I think the question is whether you’re so excited that you switch all your research and start working on it, or if you’re just very excited.”

Strange maths

Strange behaviour by electrons isn’t new.

In some materials, usually at temperatures near absolute zero, electrical resistance becomes quantized. Specifically, it’s the material’s transverse resistance that does this. (An electrical current encounters opposition to its flow in both the same direction as the current — called longitudinal resistance — and in the perpendicular direction — what’s called transverse resistance.)

Quantized ‘steps’ in the transverse resistance occur at integer multiples of electron charge: 1, 2, 3 and so on. These plateaus are the result of a strange phenomenon: the electrons maintain the same transverse resistance even as charge density increases. That’s a little like vehicles on a road moving at the same speed, even with more traffic. This is known as the quantum Hall effect.

In a different set of materials, with less disorder, the transverse resistance can even display plateaus at fractions of electron charge: 2/5, 3/7 and 4/9, for example. The plateaus take these values because the electrons collectively act like particles with fractional charges — hence the fractional quantum Hall effect (FQHE).

Key to both phenomena is a strong external magnetic field, which prevents electrons from crashing into each other and enables them to interact.

The FQHE, discovered in 1982, revealed the richness of electron behaviour. No longer could physicists think of electrons as single particles; in delicate quantum arrangements, the electrons could lose their individuality and act together to create fractionally charged particles. “I think people don’t appreciate how different [the fractional] is from the integer quantum Hall effect,” says Ashvin Vishwanath, a theoretical physicist at Harvard University in Cambridge. “It’s a new world.”

Over the next few decades, theoretical physicists came up with models to explain the FQHE and predict its effects. During their exploration, a tantalizing possibility appeared: perhaps a material could exhibit resistance plateaus without any external magnetic field. The effect, now dubbed the quantum anomalous Hall effect — ‘anomalous’, for the lack of a magnetic field — was finally observed in thin ferromagnetic films by a team at Tsinghua University in Beijing, in 2012 3 .

Carbon copy

Roughly a decade later, the University of Washington team reported the FQAHE for the first time 1 , in a specially designed 2D material: two sheets of MoTe 2 stacked on top of one another and offset by a twist.

This arrangement of MoTe 2 is known as a moiré material. Originally used to refer to a patterned textile, the term has been appropriated by physicists to describe the patterns in 2D materials created from atom-thin lattices when they are stacked and then twisted, or staggered atop one another. The slight offset between atoms in different layers of the material shifts the hills and valleys of its electric potential. And it effectively acts like a powerful magnetic field, taking the place of the one needed in the quantum Hall effect and the FQHE.

Xiaodong Xu, a condensed-matter physicist at the University of Washington, talked about the MoTe 2 discovery at the APS meeting. Theory hinted that the FQAHE would appear in the material at about a 1.4º twist angle. “We spent a year on it, and we didn’t see anything,” Xu told Nature .

Then, the researchers tried a larger angle — a twist of about 4º. Immediately, they began seeing signs of the effect. Eventually, they measured the electrical resistance and spotted the signature plateaus of the FQAHE. Soon afterwards, a team led by researchers at Shanghai Jiao Tong University in China replicated the results 4 .

Meanwhile, at MIT, Ju was perfecting his technique, sandwiching graphene between layers of boron nitride. Similar to graphene, the sheets of boron nitride that Ju’s team used were a mesh of atoms linked together in a hexagonal pattern. The material’s lattice has a slightly different size from graphene’s; the mismatch creates a moiré pattern (see ‘Anomalous behaviour’).

Last month, Ju published a report 2 about seeing the characteristic plateaus. “It is a really amazing result,” Xu says. “I'm very happy to see there’s a second system.” Since then, Ju says, he’s also seen the effect when using four and six layers of graphene.

Both moiré systems have their pros and cons. MoTe 2 exhibited the effect at a few kelvin, as opposed to 0.1 kelvin for the layered graphene sandwich. (Low temperatures are required to minimize disorder in the systems.) But graphene is a cleaner and higher-quality material that is easier to measure. Experimentalists are now trying to replicate the results in graphene and find other materials that behave similarly.

Moiré than bargained for

Theorists are relatively comfortable with the MoTe 2 results, for which the FQAHE was partly predicted. But Ju’s layered graphene moiré was a shock to the community, and researchers are still struggling to explain how the effect happens. “There’s no universal consensus on what the correct theory is,” Vishwanath says. “But they all agree that it’s not the standard mechanism.” Vishwanath and his colleagues posted a preprint proposing a theory that the moiré pattern might not be that important to the FQAHE 5 .

Welcome anyons! Physicists find best evidence yet for long-sought 2D structures

One reason to doubt the importance of the moiré is the location of the electrons in the material: most of the activity is in the topmost layer of graphene, far away from the moiré pattern between the graphene and boron nitride at the bottom of the sandwich that is supposed to most strongly influence the electrons. But B. Andrei Bernevig, a theoretical physicist at Princeton University in New Jersey, and a co-author of another preprint proposing a mechanism for the FQAHE in the layered graphene 6 , urges caution about theory-based calculations, because they rely on currently unverified assumptions. He says that the moiré pattern probably matters, but less than it does in MoTe 2 .

For theorists, the uncertainty is exciting. “There are people who would say that everything has been seen in the quantum Hall effect,” Vishwanath says. But these experiments, especially the one using the layered graphene moiré, show that there are still more mysteries to uncover.
