Using Biometrics to Evaluate Visual Design

Jane Lisa Dekker

Art Department, Northern California Valley State University

UXAD 272: Strategic Web Design

Professor Juan Liu, PhD

January 29, 2020

      A vast amount of research has been conducted regarding the importance of visual design, and its role as a mediator of user’s experience when browsing a site or interacting with an interface. In the literature, visual design is one aspect of website quality. Jones and Kim (2010) define website quality as “the perceived quality of a retail website that involves a [user’s] perceptions of the retailer’s website and comprises consumer reactions towards such attributes as information, entertainment/enjoyment, usability, transaction capabilities, and design aesthetics” (p. 632).  They further examined the impact web quality and retail brand trust has on purchase intentions. Additional research examining e-commerce sites has shown web quality has an impact on both initial and continued purchase intention (Kuan, Bock, & Vathanophas, 2008), as well as consumer satisfaction (Lin, 2007). Moreso, research on the relationship between visual design and perceived usability (Stojmenovic, Pilgrim, & Lindgaard, 2014) has revealed a positive correlation between the two. As users’ ratings of visual quality increase, their ratings of perceived usability follows a similar trend. Although this research spans various domains, the reliance on self-report measures to gauge concepts like visual design and web quality is prevalent throughout much of the literature.

Although some self-report scales are validated within the literature, there are still issues with the use of self-report questionnaires. One is the reliance on the honesty of the participant. This tends to be more of an issue in studies related to questionnaires that measure characteristics of the participant, rather than objective stimuli. More relevant to this study is the issue of introspection and memory. Surveys are often distributed after a task is completed, and its accuracy is dependent on the ability of the participant to remember their experience during the study. Multiple research studies have shown that human memory is far from static. This can

be dangerous if a researcher chooses to solely rely on self-report methods to test a hypothesis. We believe these self-report methods in tandem with biometric methods can help ensure the validity of the questionnaires, and provide information beyond the scope of self-report scales.

Research Questions

      We know from previous research that the quality of websites mediates many aspects of e-commerce, and provides insight as to how consumers view the webpages in general.  However, simply knowing a webpage is perceived as lower quality doesn’t give insight as to what aspects of a page are disliked by a user. Additionally, it’s possible that the user is misremembering aspects of the webpage or being dishonest in their assessment. Using eye tracking metrics, galvanic skin response, and facial expression measures in tandem with a scale aimed at measuring visual design quality has a couple of identifiable benefits. Using both can potentially identify patterns amongst the biometric measures and the questionnaire, which would strengthen the validity of the results. More so, the eye tracking data has the potential to identify patterns amongst websites of lower or higher quality.

If found, these patterns can be used to evaluate particular aspects of a page that are impacting the quality of a webpage. Overall, we are interested in answering two questions:

Research Question 1 : Can attitudinal changes regarding substantial website redesigns be captured using biometric measures?

Research Question 2 : How do biometric measures correlate with self-reported measures of visual appeal?

      Answering these questions has the potential to provide a method of justification for design changes, ranging from minor tweak to complete rebrands. There is not an easy way for companies to quantitatively analyze visual design decisions. A method for doing so would help companies evaluate visual designs before implementation in order to cost-justify them. To this end, we hope to demonstrate that biometric measurements can be used with questionnaires to verify and validate potential design changes a company or organization might want to implement.

      By examining data from test subjects during a brief exposure to several websites, we hoped to explore the relationship between the self-reported evaluation of visual design quality and key biometric measurements of a subject’s emotional valence and arousal. Subjects were exposed to ten pairs of websites before and after a substantial visual design change and asked to evaluate the website based on their initial impressions of the site’s visual design quality using the VisAWI-S scale, as shown in Table 1.  

During this assessment we collected GSR, facial expressions (limited by errors in initial study configuration), pupillary response, and fixation data using iMotions software coupled with a Tobii eye tracker, Shimmer GSR device, and Affdex facial expression analysis toolkit. This data was analyzed, in Table 2, to discover relationships between the independent and dependent variables, as well as relationships between certain dependent variables.

Levels of organization for a research paper outline

First level of organization, second level of organization, third level of organization, fourth level of organization, tips for writing a research paper outline, research paper outline template, my research paper outline is complete: what are the next steps, frequently asked questions about a research paper outline, related articles.

The outline is the skeleton of your research paper. Simply start by writing down your thesis and the main ideas you wish to present. This will likely change as your research progresses; therefore, do not worry about being too specific in the early stages of writing your outline.

A research paper outline typically contains between two and four layers of organization. The first two layers are the most generalized. Each layer thereafter will contain the research you complete and presents more and more detailed information.

The levels are typically represented by a combination of Roman numerals, Arabic numerals, uppercase letters, lowercase letters but may include other symbols. Refer to the guidelines provided by your institution, as formatting is not universal and differs between universities, fields, and subjects. If you are writing the outline for yourself, you may choose any combination you prefer.

This is the most generalized level of information. Begin by numbering the introduction, each idea you will present, and the conclusion. The main ideas contain the bulk of your research paper 's information. Depending on your research, it may be chapters of a book for a literature review , a series of dates for a historical research paper, or the methods and results of a scientific paper.

I. Introduction

II. Main idea

III. Main idea

IV. Main idea

V. Conclusion

The second level consists of topics which support the introduction, main ideas, and the conclusion. Each main idea should have at least two supporting topics listed in the outline.

If your main idea does not have enough support, you should consider presenting another main idea in its place. This is where you should stop outlining if this is your first draft. Continue your research before adding to the next levels of organization.

  • A. Background information
  • B. Hypothesis or thesis
  • A. Supporting topic
  • B. Supporting topic

The third level of organization contains supporting information for the topics previously listed. By now, you should have completed enough research to add support for your ideas.

The Introduction and Main Ideas may contain information you discovered about the author, timeframe, or contents of a book for a literature review; the historical events leading up to the research topic for a historical research paper, or an explanation of the problem a scientific research paper intends to address.

  • 1. Relevant history
  • 2. Relevant history
  • 1. The hypothesis or thesis clearly stated
  • 1. A brief description of supporting information
  • 2. A brief description of supporting information

The fourth level of organization contains the most detailed information such as quotes, references, observations, or specific data needed to support the main idea. It is not typical to have further levels of organization because the information contained here is the most specific.

  • a) Quotes or references to another piece of literature
  • b) Quotes or references to another piece of literature

Tip: The key to creating a useful outline is to be consistent in your headings, organization, and levels of specificity.

  • Be Consistent : ensure every heading has a similar tone. State the topic or write short sentences for each heading but avoid doing both.
  • Organize Information : Higher levels of organization are more generally stated and each supporting level becomes more specific. The introduction and conclusion will never be lower than the first level of organization.
  • Build Support : Each main idea should have two or more supporting topics. If your research does not have enough information to support the main idea you are presenting, you should, in general, complete additional research or revise the outline.

By now, you should know the basic requirements to create an outline for your paper. With a content framework in place, you can now start writing your paper . To help you start right away, you can use one of our templates and adjust it to suit your needs.

After completing your outline, you should:

  • Title your research paper . This is an iterative process and may change when you delve deeper into the topic.
  • Begin writing your research paper draft . Continue researching to further build your outline and provide more information to support your hypothesis or thesis.
  • Format your draft appropriately . MLA 8 and APA 7 formats have differences between their bibliography page, in-text citations, line spacing, and title.
  • Finalize your citations and bibliography . Use a reference manager like Paperpile to organize and cite your research.
  • Write the abstract, if required . An abstract will briefly state the information contained within the paper, results of the research, and the conclusion.

An outline is used to organize written ideas about a topic into a logical order. Outlines help us organize major topics, subtopics, and supporting details. Researchers benefit greatly from outlines while writing by addressing which topic to cover in what order.

The most basic outline format consists of: an introduction, a minimum of three topic paragraphs, and a conclusion.

You should make an outline before starting to write your research paper. This will help you organize the main ideas and arguments you want to present in your topic.

  • Consistency: ensure every heading has a similar tone. State the topic or write short sentences for each heading but avoid doing both.
  • Organization : Higher levels of organization are more generally stated and each supporting level becomes more specific. The introduction and conclusion will never be lower than the first level of organization.
  • Support : Each main idea should have two or more supporting topics. If your research does not have enough information to support the main idea you are presenting, you should, in general, complete additional research or revise the outline.

Research Paper Fundamentals

How to choose a topic or question, how to create a working hypothesis or thesis, common research paper methodologies, how to gather and organize evidence , how to write an outline for your research paper, how to write a rough draft, how to revise your draft, how to produce a final draft, resources for teachers .

It is not fair to say that no one writes anymore. Just about everyone writes text messages, brief emails, or social media posts every single day. Yet, most people don't have a lot of practice with the formal, organized writing required for a good academic research paper. This guide contains links to a variety of resources that can help demystify the process. Some of these resources are intended for teachers; they contain exercises, activities, and teaching strategies. Other resources are intended for direct use by students who are struggling to write papers, or are looking for tips to make the process go more smoothly.

The resources in this section are designed to help students understand the different types of research papers, the general research process, and how to manage their time. Below, you'll find links from university writing centers, the trusted Purdue Online Writing Lab, and more.

What is an Academic Research Paper?

"Genre and the Research Paper" (Purdue OWL)

There are different types of research papers. Different types of scholarly questions will lend themselves to one format or another. This is a brief introduction to the two main genres of research paper: analytic and argumentative. 

"7 Most Popular Types of Research Papers" (Personal-writer.com)

This resource discusses formats that high school students commonly encounter, such as the compare and contrast essay and the definitional essay. Please note that the inclusion of this link is not an endorsement of this company's paid service.

How to Prepare and Plan Out Writing a Research Paper

Teachers can give their students a step-by-step guide like these to help them understand the different steps of the research paper process. These guides can be combined with the time management tools in the next subsection to help students come up with customized calendars for completing their papers.

"Ten Steps for Writing Research Papers" (American University)  

This resource from American University is a comprehensive guide to the research paper writing process, and includes examples of proper research questions and thesis topics.

"Steps in Writing a Research Paper" (SUNY Empire State College)

This guide breaks the research paper process into 11 steps. Each "step" links to a separate page, which describes the work entailed in completing it.

How to Manage Time Effectively

The links below will help students determine how much time is necessary to complete a paper. If your sources are not available online or at your local library, you'll need to leave extra time for the Interlibrary Loan process. Remember that, even if you do not need to consult secondary sources, you'll still need to leave yourself ample time to organize your thoughts.

"Research Paper Planner: Timeline" (Baylor University)

This interactive resource from Baylor University creates a suggested writing schedule based on how much time a student has to work on the assignment.

"Research Paper Planner" (UCLA)

UCLA's library offers this step-by-step guide to the research paper writing process, which also includes a suggested planning calendar.

There's a reason teachers spend a long time talking about choosing a good topic. Without a good topic and a well-formulated research question, it is almost impossible to write a clear and organized paper. The resources below will help you generate ideas and formulate precise questions.

"How to Select a Research Topic" (Univ. of Michigan-Flint)

This resource is designed for college students who are struggling to come up with an appropriate topic. A student who uses this resource and still feels unsure about his or her topic should consult the course instructor for further personalized assistance.

"25 Interesting Research Paper Topics to Get You Started" (Kibin)

This resource, which is probably most appropriate for high school students, provides a list of specific topics to help get students started. It is broken into subsections, such as "paper topics on local issues."

This introduction to research questions includes some embedded videos, as well as links to scholarly articles on research questions. This resource would be most appropriate for teachers who are planning lessons on research paper fundamentals.

"How to Write a Research Question the Right Way" (Kibin)

This student-focused resource provides more detail on writing research questions. The language is accessible, and there are embedded videos and examples of good and bad questions.

It is important to have a rough hypothesis or thesis in mind at the beginning of the research process. People who have a sense of what they want to say will have an easier time sorting through scholarly sources and other information. The key, of course, is not to become too wedded to the draft hypothesis or thesis. Just about every working thesis gets changed during the research process.

CrashCourse Video: "Sociology Research Methods" (YouTube)

Although this video is tailored to sociology students, it is applicable to students in a variety of social science disciplines. This video does a good job demonstrating the connection between the brainstorming that goes into selecting a research question and the formulation of a working hypothesis.

"How to Write a Thesis Statement for an Analytical Essay" (YouTube)

Students writing analytical essays will not develop the same type of working hypothesis as students who are writing research papers in other disciplines. For these students, developing the working thesis may happen as a part of the rough draft (see the relevant section below). 

"Research Hypothesis" (Oakland Univ.)

This resource provides some examples of hypotheses in social science disciplines like Political Science and Criminal Justice. These sample hypotheses may also be useful for students in other soft social sciences and humanities disciplines like History.

When grading a research paper, instructors look for a consistent methodology. This section will help you understand different methodological approaches used in research papers. Students will get the most out of these resources if they use them to help prepare for conversations with teachers or discussions in class.

"Types of Research Designs" (USC)

A "research design," used for complex papers, is related to the paper's method. This resource contains introductions to a variety of popular research designs in the social sciences. Although it is not the most intuitive site to read, the information here is very valuable.

The Effects of Social Media on Mental Health

University of XYZ

This study examines the relationship between social media use and mental health among college students. Data was collected through a survey of 500 students at the University of XYZ. Results suggest that social media use is significantly related to symptoms of depression and anxiety, and that the negative effects of social media are greater among frequent users.

Social media has become an increasingly important aspect of modern life, especially among young adults. While social media can have many positive effects, such as connecting people across distances and sharing information, there is growing concern about its impact on mental health. This study aims to examine the relationship between social media use and mental health among college students.

Participants: Participants were 500 college students at the University of XYZ, recruited through online advertisements and flyers posted on campus. Participants ranged in age from 18 to 25, with a mean age of 20.5 years. The sample was 60% female, 40% male, and 5% identified as non-binary or gender non-conforming.

Data was collected through an online survey administered through Qualtrics. The survey consisted of several measures, including the Patient Health Questionnaire-9 (PHQ-9) for depression symptoms, the Generalized Anxiety Disorder-7 (GAD-7) for anxiety symptoms, and questions about social media use.

Procedure :

Participants were asked to complete the online survey at their convenience. The survey took approximately 20-30 minutes to complete. Data was analyzed using descriptive statistics, correlations, and multiple regression analysis.

Results indicated that social media use was significantly related to symptoms of depression (r = .32, p < .001) and anxiety (r = .29, p < .001). Regression analysis indicated that frequency of social media use was a significant predictor of both depression symptoms (β = .24, p < .001) and anxiety symptoms (β = .20, p < .001), even when controlling for age, gender, and other relevant factors.

The results of this study suggest that social media use is associated with symptoms of depression and anxiety among college students. The negative effects of social media are greater among frequent users. These findings have important implications for mental health professionals and educators, who should consider addressing the potential negative effects of social media use in their work with young adults.

References :

References should be listed in alphabetical order according to the author’s last name. For example:

  • Chou, H. T. G., & Edge, N. (2012). “They are happier and having better lives than I am”: The impact of using Facebook on perceptions of others’ lives. Cyberpsychology, Behavior, and Social Networking, 15(2), 117-121.

Note: This is just a sample Example do not use this in your assignment.

MLA (Modern Language Association) Format

MLA (Modern Language Association) Format is as follows:

  • Page Layout : Use 8.5 x 11-inch white paper, with 1-inch margins on all sides. The font should be 12-point Times New Roman or a similar serif font.
  • Heading and Title : The first page of your research paper should include a heading and a title. The heading should include your name, your instructor’s name, the course title, and the date. The title should be centered and in title case (capitalizing the first letter of each important word).
  • In-Text Citations : Use parenthetical citations to indicate the source of your information. The citation should include the author’s last name and the page number(s) of the source. For example: (Smith 23).
  • Works Cited Page : At the end of your paper, include a Works Cited page that lists all the sources you used in your research. Each entry should include the author’s name, the title of the work, the publication information, and the medium of publication.
  • Formatting Quotations : Use double quotation marks for short quotations and block quotations for longer quotations. Indent the entire quotation five spaces from the left margin.
  • Formatting the Body : Use a clear and readable font and double-space your text throughout. The first line of each paragraph should be indented one-half inch from the left margin.

Title: The Impact of Video Games on Aggression Levels

Video games have become a popular form of entertainment among people of all ages. However, the impact of video games on aggression levels has been a subject of debate among scholars and researchers. While some argue that video games promote aggression and violent behavior, others argue that there is no clear link between video games and aggression levels. This research paper aims to explore the impact of video games on aggression levels among young adults.

Background:

The debate on the impact of video games on aggression levels has been ongoing for several years. According to the American Psychological Association, exposure to violent media, including video games, can increase aggression levels in children and adolescents. However, some researchers argue that there is no clear evidence to support this claim. Several studies have been conducted to examine the impact of video games on aggression levels, but the results have been mixed.

Methodology:

This research paper used a quantitative research approach to examine the impact of video games on aggression levels among young adults. A sample of 100 young adults between the ages of 18 and 25 was selected for the study. The participants were asked to complete a questionnaire that measured their aggression levels and their video game habits.

The results of the study showed that there was a significant correlation between video game habits and aggression levels among young adults. The participants who reported playing violent video games for more than 5 hours per week had higher aggression levels than those who played less than 5 hours per week. The study also found that male participants were more likely to play violent video games and had higher aggression levels than female participants.

The findings of this study support the claim that video games can increase aggression levels among young adults. However, it is important to note that the study only examined the impact of video games on aggression levels and did not take into account other factors that may contribute to aggressive behavior. It is also important to note that not all video games promote violence and aggression, and some games may have a positive impact on cognitive and social skills.

Conclusion :

In conclusion, this research paper provides evidence to support the claim that video games can increase aggression levels among young adults. However, it is important to conduct further research to examine the impact of video games on other aspects of behavior and to explore the potential benefits of video games. Parents and educators should be aware of the potential impact of video games on aggression levels and should encourage young adults to engage in a variety of activities that promote cognitive and social skills.

Title: The Impact of Social Media on Political Engagement

Name: John Smith

Class: POLS 101

Professor: Dr. Jane Doe

Date: April 8, 2023

I. Introduction:

Social media has become an integral part of our daily lives. People use social media platforms like Facebook, Twitter, and Instagram to connect with friends and family, share their opinions, and stay informed about current events. With the rise of social media, there has been a growing interest in understanding its impact on various aspects of society, including political engagement. In this paper, I will examine the relationship between social media use and political engagement, specifically focusing on how social media influences political participation and political attitudes.

II. Literature Review:

There is a growing body of literature on the impact of social media on political engagement. Some scholars argue that social media has a positive effect on political participation by providing new channels for political communication and mobilization (Delli Carpini & Keeter, 1996; Putnam, 2000). Others, however, suggest that social media can have a negative impact on political engagement by creating filter bubbles that reinforce existing beliefs and discourage political dialogue (Pariser, 2011; Sunstein, 2001).

III. Methodology:

To examine the relationship between social media use and political engagement, I conducted a survey of 500 college students. The survey included questions about social media use, political participation, and political attitudes. The data was analyzed using descriptive statistics and regression analysis.

Iv. Results:

The results of the survey indicate that social media use is positively associated with political participation. Specifically, respondents who reported using social media to discuss politics were more likely to have participated in a political campaign, attended a political rally, or contacted a political representative. Additionally, social media use was found to be associated with more positive attitudes towards political engagement, such as increased trust in government and belief in the effectiveness of political action.

V. Conclusion:

The findings of this study suggest that social media has a positive impact on political engagement, by providing new opportunities for political communication and mobilization. However, there is also a need for caution, as social media can also create filter bubbles that reinforce existing beliefs and discourage political dialogue. Future research should continue to explore the complex relationship between social media and political engagement, and develop strategies to harness the potential benefits of social media while mitigating its potential negative effects.

What is a Research Paper?

A research paper is different from a usual kind of essay and assignment. It requires more research and explanation than any other assignment and has a set structure for it. It is a complex type of academic paper. Usually, students studying science write them for their coursework and as a degree requirement.

It is generally simpler than high school term papers and a dissertation that students write in humanities and other academic groups. Research papers are common in the academic world, and students, regardless of the field of study, get them as part of their degree requirements.

The research writing skills are invaluable for everyone and not just for the students only. Young professionals and entrepreneurs benefit a lot from these skills. Writing a research paper properly means that you have to study, observe, and choose a topic. The step-by-step guide for  writing a research paper  will help you find answers to your research questions.

How to Write a Research Paper Introduction (with Examples)

How to Write a Research Paper Introduction (with Examples)

The research paper introduction section, along with the Title and Abstract, can be considered the face of any research paper. The following article is intended to guide you in organizing and writing the research paper introduction for a quality academic article or dissertation.

The research paper introduction aims to present the topic to the reader. A study will only be accepted for publishing if you can ascertain that the available literature cannot answer your research question. So it is important to ensure that you have read important studies on that particular topic, especially those within the last five to ten years, and that they are properly referenced in this section. 1 What should be included in the research paper introduction is decided by what you want to tell readers about the reason behind the research and how you plan to fill the knowledge gap. The best research paper introduction provides a systemic review of existing work and demonstrates additional work that needs to be done. It needs to be brief, captivating, and well-referenced; a well-drafted research paper introduction will help the researcher win half the battle.

The introduction for a research paper is where you set up your topic and approach for the reader. It has several key goals:

  • Present your research topic
  • Capture reader interest
  • Summarize existing research
  • Position your own approach
  • Define your specific research problem and problem statement
  • Highlight the novelty and contributions of the study
  • Give an overview of the paper’s structure

The research paper introduction can vary in size and structure depending on whether your paper presents the results of original empirical research or is a review paper. Some research paper introduction examples are only half a page while others are a few pages long. In many cases, the introduction will be shorter than all of the other sections of your paper; its length depends on the size of your paper as a whole.

The introduction in a research paper is placed at the beginning to guide the reader from a broad subject area to the specific topic that your research addresses. They present the following information to the reader

  • Scope: The topic covered in the research paper
  • Context: Background of your topic
  • Importance: Why your research matters in that particular area of research and the industry problem that can be targeted

The research paper introduction conveys a lot of information and can be considered an essential roadmap for the rest of your paper. A good introduction for a research paper is important for the following reasons:

  • It stimulates your reader’s interest: A good introduction section can make your readers want to read your paper by capturing their interest. It informs the reader what they are going to learn and helps determine if the topic is of interest to them.
  • It helps the reader understand the research background: Without a clear introduction, your readers may feel confused and even struggle when reading your paper. A good research paper introduction will prepare them for the in-depth research to come. It provides you the opportunity to engage with the readers and demonstrate your knowledge and authority on the specific topic.
  • It explains why your research paper is worth reading: Your introduction can convey a lot of information to your readers. It introduces the topic, why the topic is important, and how you plan to proceed with your research.
  • It helps guide the reader through the rest of the paper: The research paper introduction gives the reader a sense of the nature of the information that will support your arguments and the general organization of the paragraphs that will follow. It offers an overview of what to expect when reading the main body of your paper.

What are the parts of introduction in the research?

A good research paper introduction section should comprise three main elements: 2

  • What is known: This sets the stage for your research. It informs the readers of what is known on the subject.
  • What is lacking: This is aimed at justifying the reason for carrying out your research. This could involve investigating a new concept or method or building upon previous research.
  • What you aim to do: This part briefly states the objectives of your research and its major contributions. Your detailed hypothesis will also form a part of this section.

How to write a research paper introduction?

The first step in writing the research paper introduction is to inform the reader what your topic is and why it’s interesting or important. This is generally accomplished with a strong opening statement. The second step involves establishing the kinds of research that have been done and ending with limitations or gaps in the research that you intend to address. Finally, the research paper introduction clarifies how your own research fits in and what problem it addresses. If your research involved testing hypotheses, these should be stated along with your research question. The hypothesis should be presented in the past tense since it will have been tested by the time you are writing the research paper introduction.

The following key points, with examples, can guide you when writing the research paper introduction section:

  • Highlight the importance of the research field or topic
  • Describe the background of the topic
  • Present an overview of current research on the topic

Example: The inclusion of experiential and competency-based learning has benefitted electronics engineering education. Industry partnerships provide an excellent alternative for students wanting to engage in solving real-world challenges. Industry-academia participation has grown in recent years due to the need for skilled engineers with practical training and specialized expertise. However, from the educational perspective, many activities are needed to incorporate sustainable development goals into the university curricula and consolidate learning innovation in universities.

  • Reveal a gap in existing research or oppose an existing assumption
  • Formulate the research question

Example: There have been plausible efforts to integrate educational activities in higher education electronics engineering programs. However, very few studies have considered using educational research methods for performance evaluation of competency-based higher engineering education, with a focus on technical and or transversal skills. To remedy the current need for evaluating competencies in STEM fields and providing sustainable development goals in engineering education, in this study, a comparison was drawn between study groups without and with industry partners.

  • State the purpose of your study
  • Highlight the key characteristics of your study
  • Describe important results
  • Highlight the novelty of the study.
  • Offer a brief overview of the structure of the paper.

Example: The study evaluates the main competency needed in the applied electronics course, which is a fundamental core subject for many electronics engineering undergraduate programs. We compared two groups, without and with an industrial partner, that offered real-world projects to solve during the semester. This comparison can help determine significant differences in both groups in terms of developing subject competency and achieving sustainable development goals.

The purpose of the research paper introduction is to introduce the reader to the problem definition, justify the need for the study, and describe the main theme of the study. The aim is to gain the reader’s attention by providing them with necessary background information and establishing the main purpose and direction of the research.

The length of the research paper introduction can vary across journals and disciplines. While there are no strict word limits for writing the research paper introduction, an ideal length would be one page, with a maximum of 400 words over 1-4 paragraphs. Generally, it is one of the shorter sections of the paper as the reader is assumed to have at least a reasonable knowledge about the topic. 2 For example, for a study evaluating the role of building design in ensuring fire safety, there is no need to discuss definitions and nature of fire in the introduction; you could start by commenting upon the existing practices for fire safety and how your study will add to the existing knowledge and practice.

When deciding what to include in the research paper introduction, the rest of the paper should also be considered. The aim is to introduce the reader smoothly to the topic and facilitate an easy read without much dependency on external sources. 3 Below is a list of elements you can include to prepare a research paper introduction outline and follow it when you are writing the research paper introduction. Topic introduction: This can include key definitions and a brief history of the topic. Research context and background: Offer the readers some general information and then narrow it down to specific aspects. Details of the research you conducted: A brief literature review can be included to support your arguments or line of thought. Rationale for the study: This establishes the relevance of your study and establishes its importance. Importance of your research: The main contributions are highlighted to help establish the novelty of your study Research hypothesis: Introduce your research question and propose an expected outcome. Organization of the paper: Include a short paragraph of 3-4 sentences that highlights your plan for the entire paper

Cite only works that are most relevant to your topic; as a general rule, you can include one to three. Note that readers want to see evidence of original thinking. So it is better to avoid using too many references as it does not leave much room for your personal standpoint to shine through. Citations in your research paper introduction support the key points, and the number of citations depend on the subject matter and the point discussed. If the research paper introduction is too long or overflowing with citations, it is better to cite a few review articles rather than the individual articles summarized in the review. A good point to remember when citing research papers in the introduction section is to include at least one-third of the references in the introduction.

The literature review plays a significant role in the research paper introduction section. A good literature review accomplishes the following: Introduces the topic – Establishes the study’s significance – Provides an overview of the relevant literature – Provides context for the study using literature – Identifies knowledge gaps However, remember to avoid making the following mistakes when writing a research paper introduction: Do not use studies from the literature review to aggressively support your research Avoid direct quoting Do not allow literature review to be the focus of this section. Instead, the literature review should only aid in setting a foundation for the manuscript.

Remember the following key points for writing a good research paper introduction: 4

  • Avoid stuffing too much general information: Avoid including what an average reader would know and include only that information related to the problem being addressed in the research paper introduction. For example, when describing a comparative study of non-traditional methods for mechanical design optimization, information related to the traditional methods and differences between traditional and non-traditional methods would not be relevant. In this case, the introduction for the research paper should begin with the state-of-the-art non-traditional methods and methods to evaluate the efficiency of newly developed algorithms.
  • Avoid packing too many references: Cite only the required works in your research paper introduction. The other works can be included in the discussion section to strengthen your findings.
  • Avoid extensive criticism of previous studies: Avoid being overly critical of earlier studies while setting the rationale for your study. A better place for this would be the Discussion section, where you can highlight the advantages of your method.
  • Avoid describing conclusions of the study: When writing a research paper introduction remember not to include the findings of your study. The aim is to let the readers know what question is being answered. The actual answer should only be given in the Results and Discussion section.

To summarize, the research paper introduction section should be brief yet informative. It should convince the reader the need to conduct the study and motivate him to read further.

Introduction The melamine controversy that erupted during the last quarter of year 2008 brought people’s attention back to the debates between breastfeeding and the use of breast milk substitutes like commercial infant formula. This wasn’t the first time that infant formula had caused illnesses and even deaths to infants worldwide - hence the continuous campaign of World Health Organization (WHO) and UNICEF along with other breastfeeding advocates, for mothers to breastfeed their children at least until 6 months of age. Infant feeding practices refer generally to meet the nutritional and immunological needs of the baby. A study of infant feeding practices was carried out on a sample of 100 mother and infant pairs. The results revealed that only 20% of mothers in the study currently exclusively breastfeed their babies. It also shows that socio-economic factors like mother’s work status, marital status and educational attainment had direct bearing on these practices. Employed mothers tend to cease from breastfeeding their babies and eventually stop and just resort to formula feeding as they go back to work. The study also showed that mothers who are married and living with their partners are more likely to breastfeed their infants than single mothers. Those with higher educational attainment resort more to formula feeding and mixed feeding than those with lower educational attainment. Health care professionals influence mothers the most when it comes to infant feeding decisions. Methodology Type of Research The type of research that will be used in this study is qualitative research and quantitative research. Qualitative researchers aim to gather an in-depth understanding of human behavior and the reasons that govern such behavior. The discipline investigates the “why” and “how” of decision making. Besides this, the researcher will also examine the phenomenon through observations in numerical representations and through statistical analysis. Along with questionnaires that will be given out to respondents for the statistical representation of the findings in the study, interviews with the respondents and a few experts in this field will also be conducted. Sampling Method The research sampling method that will be used in this study is random sampling to obtain a more scientific result that could be used to represent the entirety of the population. A list of all health care facilities (maternity and lying-in clinics, public and private hospitals, health centers) was acquired from the Las Piñas City Hall. From 20 barangays, 3 will be picked through random sampling. The health care facilities and institutions in these three barangays will then be the target sources of respondents of the researcher. The health care facilities and institutions will be contacted to obtain a verbal consent to administer the questionnaire to mothers at their places. A letter of consent will also be sent to them along with a sample copy of the questionnaire that will be used, as well as the protocol of the researcher. A letter was also addressed to the City Health Officer to obtain endorsement and consent to conduct a research in selected barangays and distribute questionnaires to the mothers in the vicinity. Data collection was conducted throughout the facilities‟ and health centers‟ operating hours from Mondays through Sundays in order to include both working and non-working mothers. Respondents The respondents in this research will all be coming from one single location - Las Piñas City, specifically the randomly selected barangays of Pamplona I, CAA/BF International and Pamplona III. The researcher chose Las Piñas City because of the socio-economic conditions present in the area that is relevant to the study and also as it fits the time frame and resources of the researcher. The randomly sampled respondents will be asked by the researcher for consent and approval to answer the questionnaire until the desired number of respondents which is 100 is reached. The opinion of experts will also be sought in this research to provide explanations regarding the respondents‟ infant feeding behaviors and practices. Questionnaire The questionnaire requires information about the socio-economic and demographic background of the mother. It also has questions related to previous infant feeding practices and the birth of her youngest infant and also regarding the baby’s general health and age. Statements that are perceived to be factors that influence mothers‟ infant feeding decisions were presented. The description of the type of infant formula given by formula and mixed feeding mothers will also be asked in the material. Conclusion Majority of the mothers formula feed their child and only a minority exclusively breastfeeds their children, especially as per recommendation of the World Health Organization. While majority of the mothers in this study showed a positive attitude towards breastfeeding, most of them decided only to formula feed due to the reasons of insufficient milk supply and work. Based on the results of the study, the educational attainment, work status, marital status, and seminars in the barangay the respondents are part of, about breastfeeding, are the significant factors that affect the infant feeding decision of mothers in Las Piñas City. Majority of the mothers that served as respondents in this study fall under the age range of 17-30 years old. More than half of them were also college graduates while a significant number are undergraduates and have only reached until high school. Most of the mothers are housewives and the others remaining have full-time jobs, part-time jobs and self-employed. A few of them are still students. While majority of them were married, a lot were still in a status of live-in and are single. More than half of the mothers did not have previous children before the current one. Majority of the respondents also have an annual gross household income that does not exceed P50,000. Among the several information sources namely, media through televisions/radios and printed/published materials, the social support system comprised of the mother’s family, friends and other relatives and health institutions, the mothers who give their babies infant formula are influenced the most by health care institutions through health professionals and other health care personnel. They influence the mothers in deciding to feed the baby with formula and in choosing, as well, which brand of formula is best for their babies. Mothers trust their baby’s doctor because of their expertise in the said field hence this kind of relation is achieved. Mothers were overall not concerned about the possible side effects of breastfeeding as a few were only worried as shown in the data presented.       It can be concluded that numerous internal as well as external factors influence a mother in making infant feeding decisions, and a greater fraction of these is socio-economic in nature.

Study Suggests Genetics as a Cause, Not Just a Risk, for Some Alzheimer’s

People with two copies of the gene variant APOE4 are almost certain to get Alzheimer’s, say researchers, who proposed a framework under which such patients could be diagnosed years before symptoms.

By Pam Belluck

Scientists are proposing a new way of understanding the genetics of Alzheimer’s that would mean that up to a fifth of patients would be considered to have a genetically caused form of the disease.

Currently, the vast majority of Alzheimer’s cases do not have a clearly identified cause. The new designation, proposed in a study published Monday, could broaden the scope of efforts to develop treatments, including gene therapy, and affect the design of clinical trials.

It could also mean that hundreds of thousands of people in the United States alone could, if they chose, receive a diagnosis of Alzheimer’s before developing any symptoms of cognitive decline, although there currently are no treatments for people at that stage.

The new classification would make this type of Alzheimer’s one of the most common genetic disorders in the world, medical experts said.

“This reconceptualization that we’re proposing affects not a small minority of people,” said Dr. Juan Fortea, an author of the study and the director of the Sant Pau Memory Unit in Barcelona, Spain. “Sometimes we say that we don’t know the cause of Alzheimer’s disease,” but, he said, this would mean that about 15 to 20 percent of cases “can be tracked back to a cause, and the cause is in the genes.”

The idea involves a gene variant called APOE4. Scientists have long known that inheriting one copy of the variant increases the risk of developing Alzheimer’s, and that people with two copies, inherited from each parent, have vastly increased risk.

The new study , published in the journal Nature Medicine, analyzed data from over 500 people with two copies of APOE4, a significantly larger pool than in previous studies. The researchers found that almost all of those patients developed the biological pathology of Alzheimer’s, and the authors say that two copies of APOE4 should now be considered a cause of Alzheimer’s — not simply a risk factor.

The patients also developed Alzheimer’s pathology relatively young, the study found. By age 55, over 95 percent had biological markers associated with the disease. By 65, almost all had abnormal levels of a protein called amyloid that forms plaques in the brain, a hallmark of Alzheimer’s. And many started developing symptoms of cognitive decline at age 65, younger than most people without the APOE4 variant.

“The critical thing is that these individuals are often symptomatic 10 years earlier than other forms of Alzheimer’s disease,” said Dr. Reisa Sperling, a neurologist at Mass General Brigham in Boston and an author of the study.

She added, “By the time they are picked up and clinically diagnosed, because they’re often younger, they have more pathology.”

People with two copies, known as APOE4 homozygotes, make up 2 to 3 percent of the general population, but are an estimated 15 to 20 percent of people with Alzheimer’s dementia, experts said. People with one copy make up about 15 to 25 percent of the general population, and about 50 percent of Alzheimer’s dementia patients.

The most common variant is called APOE3, which seems to have a neutral effect on Alzheimer’s risk. About 75 percent of the general population has one copy of APOE3, and more than half of the general population has two copies.

Alzheimer’s experts not involved in the study said classifying the two-copy condition as genetically determined Alzheimer’s could have significant implications, including encouraging drug development beyond the field’s recent major focus on treatments that target and reduce amyloid.

Dr. Samuel Gandy, an Alzheimer’s researcher at Mount Sinai in New York, who was not involved in the study, said that patients with two copies of APOE4 faced much higher safety risks from anti-amyloid drugs.

When the Food and Drug Administration approved the anti-amyloid drug Leqembi last year, it required a black-box warning on the label saying that the medication can cause “serious and life-threatening events” such as swelling and bleeding in the brain, especially for people with two copies of APOE4. Some treatment centers decided not to offer Leqembi, an intravenous infusion, to such patients.

Dr. Gandy and other experts said that classifying these patients as having a distinct genetic form of Alzheimer’s would galvanize interest in developing drugs that are safe and effective for them and add urgency to current efforts to prevent cognitive decline in people who do not yet have symptoms.

“Rather than say we have nothing for you, let’s look for a trial,” Dr. Gandy said, adding that such patients should be included in trials at younger ages, given how early their pathology starts.

Besides trying to develop drugs, some researchers are exploring gene editing to transform APOE4 into a variant called APOE2, which appears to protect against Alzheimer’s. Another gene-therapy approach being studied involves injecting APOE2 into patients’ brains.

The new study had some limitations, including a lack of diversity that might make the findings less generalizable. Most patients in the study had European ancestry. While two copies of APOE4 also greatly increase Alzheimer’s risk in other ethnicities, the risk levels differ, said Dr. Michael Greicius, a neurologist at Stanford University School of Medicine who was not involved in the research.

“One important argument against their interpretation is that the risk of Alzheimer’s disease in APOE4 homozygotes varies substantially across different genetic ancestries,” said Dr. Greicius, who cowrote a study that found that white people with two copies of APOE4 had 13 times the risk of white people with two copies of APOE3, while Black people with two copies of APOE4 had 6.5 times the risk of Black people with two copies of APOE3.

“This has critical implications when counseling patients about their ancestry-informed genetic risk for Alzheimer’s disease,” he said, “and it also speaks to some yet-to-be-discovered genetics and biology that presumably drive this massive difference in risk.”

Under the current genetic understanding of Alzheimer’s, less than 2 percent of cases are considered genetically caused. Some of those patients inherited a mutation in one of three genes and can develop symptoms as early as their 30s or 40s. Others are people with Down syndrome, who have three copies of a chromosome containing a protein that often leads to what is called Down syndrome-associated Alzheimer’s disease .

Dr. Sperling said the genetic alterations in those cases are believed to fuel buildup of amyloid, while APOE4 is believed to interfere with clearing amyloid buildup.

Under the researchers’ proposal, having one copy of APOE4 would continue to be considered a risk factor, not enough to cause Alzheimer’s, Dr. Fortea said. It is unusual for diseases to follow that genetic pattern, called “semidominance,” with two copies of a variant causing the disease, but one copy only increasing risk, experts said.

The new recommendation will prompt questions about whether people should get tested to determine if they have the APOE4 variant.

Dr. Greicius said that until there were treatments for people with two copies of APOE4 or trials of therapies to prevent them from developing dementia, “My recommendation is if you don’t have symptoms, you should definitely not figure out your APOE status.”

He added, “It will only cause grief at this point.”

Finding ways to help these patients cannot come soon enough, Dr. Sperling said, adding, “These individuals are desperate, they’ve seen it in both of their parents often and really need therapies.”

The Fight Against Alzheimer’s Disease

Alzheimer’s is the most common form of dementia, but much remains unknown about this daunting disease..

How is Alzheimer’s diagnosed? What causes Alzheimer’s? We answered some common questions .

A study suggests that genetics can be a cause of Alzheimer’s , not just a risk, raising the prospect of diagnosis years before symptoms appear.

Determining whether someone has Alzheimer’s usually requires an extended diagnostic process . But new criteria could lead to a diagnosis on the basis of a simple blood test .

The F.D.A. has given full approval to the Alzheimer’s drug Leqembi. Here is what to know about i t.

Title: an efficient finite difference approximation via a double sample-recycling approach.

Abstract: Estimating stochastic gradients is pivotal in fields like service systems within operations research. The classical method for this estimation is the finite difference approximation, which entails generating samples at perturbed inputs. Nonetheless, practical challenges persist in determining the perturbation and obtaining an optimal finite difference estimator in the sense of possessing the smallest mean squared error (MSE). To tackle this problem, we propose a double sample-recycling approach in this paper. Firstly, pilot samples are recycled to estimate the optimal perturbation. Secondly, recycling these pilot samples again and generating new samples at the estimated perturbation, lead to an efficient finite difference estimator. We analyze its bias, variance and MSE. Our analyses demonstrate a reduction in asymptotic variance, and in some cases, a decrease in asymptotic bias, compared to the optimal finite difference estimator. Therefore, our proposed estimator consistently coincides with, or even outperforms the optimal finite difference estimator. In numerical experiments, we apply the estimator in several examples, and numerical results demonstrate its robustness, as well as coincidence with the theory presented, especially in the case of small sample sizes.

In this paper we estimate the Head Count Ratio (HCR) and two fuzzy poverty measures at provincial level in Morocco using data from the Household Budget Survey (HBS). As the sample size is not always sufficient to provide reliable direct estimates, we use a Fay–Herriot model with additive logistic transformation and meteorological covariates to obtain estimates with lower mean squared errors. Among our main results, we find out that the Fuzzy Monetary measure provides more accurate estimates than the Head Count Ratio when conducting small area estimation exercises. Also, we empirically notice that the set of covariates at our disposal allows us to obtain better estimates for each supplementary poverty measure that we identify.

These are known as area-level small area methods to distinguish from unit-level methods where the subscript denotes a unit of the sample and not an area.

The use of covariates with error on SAE is an open field of research and only few articles have been published (see:Chandra et al., 2018 ; Datta et al., 2018 ; Würz et al., 2022 )

According with NASA definition a wet day is a day with precipitation \(> 1\)  mm.

Eurostat ( 2013 ) discourage the use of CV for percentages or proportions. Although this applies to statistics like the head count ratio, the statistic that we report here is slightly different in that it is an average of a membership function. Kvålseth ( 2017 ) proposes to use a second-order alternative (CV2) that is not influenced by values near 0. However, in this context, we still prefer to use the CV as it is more common and widely used in the SAE context. Readers interested in computing the CV2 can refer to the values in the Appendix; the results are almost identical.

Despite its Earth-like size and source material 1 , 2 , Venus is extremely dry 3 , 4 , indicating near-total water loss to space by means of hydrogen outflow from an ancient, steam-dominated atmosphere 5 , 6 . Such hydrodynamic escape likely removed most of an initial Earth-like 3-km global equivalent layer (GEL) of water but cannot deplete the atmosphere to the observed 3-cm GEL because it shuts down below about 10–100 m GEL 5 , 7 . To complete Venus water loss, and to produce the observed bulk atmospheric enrichment in deuterium of about 120 times Earth 8 , 9 , nonthermal H escape mechanisms still operating today are required 10 , 11 . Early studies identified these as resonant charge exchange 12 , 13 , 14 , hot oxygen impact 15 , 16 and ion outflow 17 , 18 , establishing a consensus view of H escape 10 , 19 that has since received only minimal updates 20 . Here we show that this consensus omits the most important present-day H loss process, HCO + dissociative recombination. This process nearly doubles the Venus H escape rate and, consequently, doubles the amount of present-day volcanic water outgassing and/or impactor infall required to maintain a steady-state atmospheric water abundance. These higher loss rates resolve long-standing difficulties in simultaneously explaining the measured abundance and isotope ratio of Venusian water 21 , 22 and would enable faster desiccation in the wake of speculative late ocean scenarios 23 . Design limitations prevented past Venus missions from measuring both HCO + and the escaping hydrogen produced by its recombination; future spacecraft measurements are imperative.
