Survey analysis using Likert scale

Likert scale
Likert scale is a psychometric scale (i.e. a scale which measures individual differences) that is commonly used in survey research involving questionnaires (i.e. instrument). Each question or statement of the questionnaire forms the “Likert item”. Likert item measures the participants’ level of agreement to a statement, such as “strongly agree” or “neutral” or “disagree” which are orderly numbered. Generally 5 levels of responses are used i.e.   1. Strongly disagree, 2. Disagree, 3. Neither agrees nor disagrees, 4. Agree 5. Strongly agree. However, more than 5 levels i.e. 7 and 9 levels are also sometimes used.

Before analyzing the Likert scale data, the reliability of the instrument or scale is performed. This is achieved by three different ways. First, the uniformity in response within the instrument (i.e. internal consistency) is measured by estimating the Cronbach’s alpha. A Cronbach’s alpha value of ≥0.7 is accepted. Second, the test-retest reliability is calculated.  In SPSS, the test-retest is calculated by bivariate correlation which is denoted by the Pearson’s correlation coefficient (r). Third, the inter-rater reliability is also estimated as test-retest in SPSS.

After determining the reliability of the instrument, analysis of Likert data is carried out. Each Likert item can be analyzed either separately (also called as Likert-type data) or summed to create a score for a group of items (summative scales, Likert scales). Each Likert scale consists of at least four or more Likert-type items, all measuring a single variable.

  1. Likert-type data is an ordinal data, i.e. we can only say that one score is higher than another. Due to the ordinal nature of the data, generally parametric tests (i.e. t-test, ANOVA) are not applied. Rather, non-parametric tests such as Mann Whitney-U test, Wilcoxon signed-rank test, Kruskal-Wallis test should be used. Descriptive statistics used for Likert-type data includes mode or median for measuring central tendency and frequencies for variability. Further analysis appropriate for ordinal scale items includes the chi-square measure of association, Kendall Tau B, and Kendall Tau C.
  2. Likert scale data, on the other hand, are analyzed as interval data. Since the data are of interval, parametric tests are used for analysis of Likert scale. Analysis that can be performed includes mean for central tendency, standard deviations for variability, Pearson’s r for bivariate analysis, t-test and ANOVA for comparing group means, and regression procedures for associations.
  3. When Likert-type or Likert scale data can be reduced to nominal level i.e. yes vs. no, agree vs. disagree, then, chi-square test, Cochran Q test, and Mc Nemar test can also be performed.

Further, Likert scales may be subject to biases from several causes. Central tendency bias occurs when respondents may avoid using extreme response categories; acquiescence bias occurs when respondents agree with statements as presented and social desirability bias occurs when respondents try to represent themselves or their institution more positively. All the biases can be checked by conducting a pilot survey before the actual study. If any biases are observed the questionnaire can be modified accordingly.  Crafting a scale with an equal number of positive and negative statements can counteract the problem of acquiescence bias. Central tendency bias can be avoided by either making the survey questionnaire short or by forcing comparable rating i.e and/or by randomizing the questions. Social desirability bias can be prevented by implementing the all the above methods i.e. to minimize central tendency bias and acquiescence bias and also by making the questions indirect.

Trump releases his 100 days plan- What for Science?

Electing Donald Trump as the 45th American President will bring about scads of policy reforms, even faster than the people realize. Starting from freezing the employee recruitments to the scrapping of Obamacare initiatives are all on the list! In addition, the breakneck statements and views of Donald Trump on various scientific facts have also sparked strong reactions among academics. However, the term “Science” has turned out to be a jargon for the Republicans and has found no special mention in the 100 days plan. However, we will have a bird’s eye view on the Trump’s blueprint that he would gift the Americans and the world community this New Year, and figure out if the science facts have been addressed to.

Trump – Throwing on off Policy fetters
Trump’s hard-line positions on immigration — including his commitment towards barring Muslims or terror-prone nationals from entering the US, a plan for wall building across the Mexico borders, imbibing visa restrictions, prioritizing American workers, and the termination of job programs for foreign youths, have surely perturbed the research advocates. Such decisions could sidetrack many talented international students or researchers from studying or working at US institutions. The future of foreign research scholars in the USA could be jeopardized due to such visa restrictions.

Science Facts vs. Trump’s Contradiction- Will it affect R&D funding?
The US has been a major investor of federal dollars in the field of R&D. “The entire business of the US academic biomedical research enterprise is based on federal dollars. Without that, it would collapse,” says Ethan Weiss, an associate professor, University of California. Trump’s shockingly ignorant views on vaccination for children with autism, and calling climate change a hoax and data to be unrealistic, pulling out US (the second most carbon generator) from the Paris climate change submit), curtailing the funds to UN for supporting climate change initiatives, and calling NASA as a logistics agency, have surely put him under the scanner of the intellectuals.
As per the statement released in September, by Donald Trump, he says that “there are increasing demands to curtail spending and to balance the federal budget; we must make the commitment to invest in science, engineering, healthcare and other areas that will make the lives of Americans better, safer and more prosperous.” In an interview by sciencedebate.org, Trump added that “scientific advances do require long-term investment.” In spite of such speculations, the fate of R&D industry is too early to predict. However, before the commencement of 2017, the present US Congress Govt. could approve spending bills before Christmas. These bills will raise the National Institute of Health funding as well as the NSF budget. During the first year of Trump’s presidency, the public funding will be secured.

Uncertain change in the climate
Trump’s election could factor into climate negotiations and be a setback for the upcoming climate change meets. When the world is thinking of implementing Paris agreement, the exit of the US from the Paris summit can be an unfortunate development and the pledge of 800 million USD as the annual contribution to the United Nations Framework Convention on Climate Change may cease. However, legally Trump would not be able to sign off the Summit within his four years tenure.

Donald trump on Healthcare reforms
The Affordable Care Act, an initiative by Obama, which is in its current incarnation, won’t survive if Trump makes good on his campaign promises. By this logic, the funds linked to birth control programs would fade away, though not immediately. Trump may defund Obamacare and associated programs like state grant for medical care. A Trumpian shift to insurance premium deductions and insurance plans sales and the opening of tax-free Health Savings Accounts may not remedy the ultimate problem of high-cost health care services in the US.

Tech Boost and Trump
The Silicon Valley may be benefitted by the manufacturing revival initiative by Trump’s govt. “There are several things that a Trump administration could do that would be beneficial to tech,” says Rob Atkinson, president of the Information Technology and Innovation Foundation. The export industry will flourish over the import, which will be part and parcel of the shifting away from the traditional start-up model and the adjusted tax and trade policy.

We know very little
The research policies and development across a wide spectrum in the US political scenario are still up in the air and have kept the scientific community optimistic (though cautiously). The outcomes of Trump’s immigration policies are also not clear. This is considered as the central pillar of his campaign, which might or might not affect research. Leighton Ku, a professor at George Washington University, said that “it’s likely that the kinds of highly-skilled scientists who immigrate to the US for school or work would still be welcome. But will they want to come?” This is a billion dollar question that still remains unanswered.

Making a Book out of your Research Paper

Making a Book out of your Research Paper
Publishing a research paper as a book is every researcher’s dream, but it is a herculean task. It requires considerable effort and perseverance to get a book published. However, in spite of the apparent difficulties, researchers must realize that by writing the research paper, they have completed a big chunk of the work required for publishing a book.

Most researchers consider their research paper to be a final product and lose sight of the fact that they already have a proofread and peer reviewed manuscript in hand, which can be developed into a book. In the process of submission and publication of their research papers, the authors already have a very good idea of the changes needed to enhance the quality of the research. Besides, they receive feedback on their research from readers, editors, and peers, which could be fruitfully utilized to develop their search into a full-fledged book. Based on the number of citations garnered by the paper and the feedbacks received, the authors gain good insights about the demand for the topic in the market. They also find it easier to identify their target audience and market. Armed with all the information, the authors will be well-positioned to market the book at the right place for their targeted audience.

However, it is important to recognize the difference between a research paper and a book, and proceed accordingly. For instance, a paper prepared for a research journal is completely different from a manuscript prepared for publication as a book. A journal basically targets a select group, such as academicians, researchers or professionals related to that field of study, so there is extensive use of jargons that would be understood by its readers. Conversely, a book is targeted at a bigger audience and should be written in a language that can be understood even by the laity. Therefore, jargons should be used sparingly and properly explained in the context.

In contrast to the tone of a research paper in a journal, a book should be written in a lucid style with a fluid and smooth narration. It requires careful chapterization, preferably with small chapters so that it retains the reader’s interest till the end. Footnotes and citations should be minimized to prevent readers from being distracted. In a book, the focus should be on the bibliography. It is a good idea to include as many relevant images as possible in the book, so as to make it interesting and provide some visual relief to the reader. Attention needs to be devoted to designing and layout, with a good cover design to boot.
Generally, the first impression of a book is formed from its title. Therefore, it is important to choose a title that attracts readers as well as conveys the theme of the book. This helps market the book to a wider readership.

It is also crucial to seek the services of a professional editing house to give the book a stamp of flawless composition. Although there are many editing services available, it is important to choose the most appropriate professional group for your book. In fact, finding a good editor could be the hardest part in the process of publishing a book.
Finally, marketing the book is an essential part of the post-publication process. As the author, the onus of marketing and popularizing the book lies squarely on your shoulders. With social media marketing playing an increasingly important role in promotions and awareness building, you could use platforms such as LinkedIn, Twitter, and Facebook at almost zero cost. You could even set up a dedicated website to open new markets for your book.

Understanding Research Paper Retraction

retraction
“The main purpose of retractions is to correct the literature and ensure its integrity rather than to punish authors who misbehave.”- COPE (Committee of Publication Ethics)

An author is expected to submit a paper after checking and rechecking the paper to ensure that it adheres to the journal guidelines and also complies with the general ethics. The paper is again peer reviewed by the journal for accuracy. However, in spite of so many checks, some papers get published with gross discrepancies and are subsequently retracted. Most often, the authors are asked to retract the paper.
A paper is bound to get retracted by editors for reasons such as:

1. Presentation of unreliable data due to misconduct or an honest error
2. Unethical research
3. Plagiarism
4. Re-presentation of data published earlier, for which the author has failed to provide proper referencing or obtain necessary permissions.

Action after detection

In many cases, the journal thoroughly investigates the kind of flaws present in the paper after issuing a warning, which is generally termed as ‘expression of concern.’ If very serious kinds of flaws, such as in correct representation of data or unethical research or plagiarism to an extent where it cannot be ignored is found then in such cases retraction of paper becomes essential. Before the editors of the journal take any action the authors are given an opportunity to retract the paper themselves without citing any reasons. Editors retract a paper as a last resort.

Information of retraction

After the decision to retract the paper has been made, the online version is marked and (or) the pdf version is watermarked ‘retracted.’ A statement is issued clearly stating all the related information about the paper and a valid reason for the retraction. The statement also states who retracted the article. Care is taken to avoid a defamatory statement and. any harmful repercussions that could mislead publications.

Effect of retraction

Retraction of a paper is a source of shame and disgrace for all stakeholders, including the author(s) and the journal. The journal has to bear the shame of not being able to filter the paper before publication and the author gets a black mark on his academic profile forever.

Purpose of retraction

Retraction is a mechanism for alerting the readers and the research fraternity about the publication of the erroneous data and findings published in the paper. It is also a warning against the use of flawed data by others.

Best time to retract

It is best to act as soon as the editor detects the flaws to avoid further damage. This will prevent readers and other researchers from being misled.

The adage “prevention is better than cure” holds true for retractions too. Therefore, the authors should take great care to check the paper carefully before submission to avoid discrepancies and the ignominy of having their paper retracted after publication.

Choosing a journal: Open access or traditional publication?

journal selection : Open access or traditional publication

What is open access publishing?

Open access (OA) publishing provides researchers and readers free access to research articles online. In case of OA journals, an article processing fee is levied on the authors after acceptance of the paper. This charge is payable by the researcher, author or the institution the author is affiliated to. However, certain OA journals do not charge any fee and support their operations through sponsorship or subscriptions of the journals.

What is traditional publishing?

Traditional publishing refers to a type of contract between the author and the publisher. In this type of publishing, the author receives a portion of the revenue generated from sales of the journals. This is also known as the “royalty payment model.”

Which route to adopt?

Various factors play a determining role for authors adopting either the open access or the traditional route for publication.

Many researchers consider the open access model as economically unsustainable because it imposes an additional financial burden on them as well as on the institute they are affiliated to. But again, it comes with a basket-full of advantages, such as a much quicker publication process compared to the traditional mode and enhanced visibility of the research to a broader audience. On the other hand, traditional publications have incorporated many reforms in their business models. They ensure manuscript quality and a brand value.

Many publishing houses place the onus on the author. They give authors the choice of either disseminating the research to a wide research community through an OA publication, or opting for the traditional mode of publication.

With the advent of the Internet, we are habituated to rapid changes in business models of the publication industry. However, the journal publication business has been relatively more resistant to change. That is a function of the prevailing academic culture, where the importance of a publication is recognized through the brand value of journals and their ability to promote the publication and win research grants.

Post-submission actions: Editorial decision and peer review process

Post submission action : Peer Review

Annually, approximately 3-4 million manuscripts are submitted to various journals for publication. Each journal initiates the ensuing publication process with the screening of the manuscript before finalizing it for the peer-review process. Screening includes analysis of the paper based on the journal’s aim, scope, and reader’s interest. The decision is also influenced by the clarity of the content and adherence to journal instructions. In most journals, around 60-70% manuscripts are rejected during the initial screening process.

Once selected by the journal editors, the paper is sent to peer reviewers. Peer reviewing is a critical assessment of the manuscript by subject experts who are not part of the journal’s editorial team. Hence, journal editors carefully select the reviewers, also known as referees, based on the latter’s expertise in the subject area so that they are competent to review papers that include technical aspects. Some journals ask the authors to recommend both preferred and non-preferred reviewers to save their time while searching for appropriate reviewers for the paper.

Peer review has become an intrinsic part of the journal publication process because it gauges the quality of the paper and determines whether the manuscript is worth publishing. Generally, journals complete the peer-review process within 3-4 weeks; however, some journals have no time restrictions.

The peer review process is categorized into three types: single-blind, double-blind, and open. The first type hides the identity of the reviewers, whereas the second hides the identities of both the authors and the reviewers. Conversely, an open peer review reveals the identities of the authors to reviewers and vice versa.

Based on the feedback received from the reviewers, the journal arrives at the following decisions:

  • Acceptance. The manuscript can be published in the submitted format.
  • Rejection. The manuscript is rejected.
  • Acceptance with minor revisions. The manuscript needs minor revisions and can be published after incorporating the revisions.
  • Acceptance after major revisions. The manuscript needs major revisions by the authors and can be considered for acceptance after the revisions are incorporated.
  • Revision and resubmission. The paper requires additional statistical and/or editorial revision followed by resubmission.

Apart from these decisions, there are few more scenarios in which a manuscript can be published. Some journals follow a reject and resubmit policy. For the authors, this involves a repetition of the entire submission process after making fundamental changes in the paper as advised by the journal editor and peer reviewers. On the other hand, few publication houses reject the paper for the target journal and advice the authors to transfer the submission to another journal within the same publication house. This is referred to as the journal cascading process.

Even if the post-submission processes apparently showcase more cons than pros of the submitted manuscript, they eventually help enhance the quality of the manuscript.

Preparing tables for research papers

How to effectively prepare tables for research papers

Tables and illustrations are important tools for efficiently communicating information and data contained in your research paper to the readers. They present complex results in a comprehensible and organized manner.

However, it is advisable to use tables and illustrations wisely so as to maximize the impact of your research.They should be organized in an easy-to-understand format to convey the information and findings collected in your research. The tabular information helps the reader identify the theme of the study more readily. Although data tables should be complete,they should not be too complex. Instead of including a large volume of data in a single unwieldy table, it is prudent to use small tables to help readers identify the important information easily.

Here are some points you should consider before drafting the tables in your research paper:

  • Finalize the results that are required to be presented in tabular form.
  • Include the data or results that are relevant to the main aim of the study without being choosy and including only those results that support your hypothesis.
  • Create each table in a lucid manner and style without cluttering it with in-table citations.
  • Number the tables in a sequence according to their occurrence in the text.
  • Don’t mix tables with figures. Maintain separate numbering systems for tables and figures.
  • Create tables in a storytelling manner. Remember that your tables communicate a story to the reader that runs parallel to the text.
  • If you are using or reproducing tables from other published articles, obtain permission from the copyright holder (usually the publisher) or/andacknowledge the source.
  • Do not repeat the tabular contents in the text again; that will create confusion among readers.
  • Use clear and informative text for each table title.
  • Take extra care while extending the data in your tables. If you have too many tables, consider using them as appendices or supplementary materials.
  • Create tables with sufficient spacing in the layout so that they do not look messy, crowded, or cluttered.
  • Do not forget to spell out abbreviations used in the tables, ideally in the footnotes.

For the reader, a research paper that is dense and text-heavy can be tiresome. Conversely, tables not only encapsulate your data lucidly, but also welcome a visual relief for the reader. They add value to the layout of your paper. Besides, and more importantly, reviewers often glance at your tabulated data and illustrations first before delving into the text. Therefore, tables can be the initial draw for a reviewer and deliver a positive impact about your research paper. If you can achieve an optimum balance among your text, tables, and illustrations, it can go a long way toward being published.

Preparing your figures for research papers

How to prepare your figures for research papers

Often a research paper is embedded with loads of data and complex results and it might not be viable to include all them in the space-constrained paper. Hence, this calls for effective presentation of the information in the form of figures or diagrams. In fact, figures are the most powerful tools that leave a strong visual impact for both reviewers and readers.

Here are few tips on how you can improve the presentation of figures in your research paper.

  • Ensure that the components of the figures are clearly visible including the lines and text.
  • Always use a standard font style and size for the figure text.
  • Every figure needs to have a legend. The legend should support your figure entirely. The reader should be able to understand your figure, paired with its legend, without going to the results or method sections.
  • All abbreviations in the figure legends need to be consolidated and spelt out.
  • All parts of the figure need to be labelled. The symbols, lines, colors, abbreviations, error bars, scale bars, and other components need to be defined and described properly.
  • If you are using photographs of your human subjects, don’t forget to obtain an informed signed consent for the same.
  • Do not be afraid to use lengthy figure and table captions—better that than confusing or incomplete ones.
  • Do not forget to cite the figure that has been taken from another source and supports your present study. Use the same citation style throughout the paper.
  • All journals have their specific requirements for formatting figures, such as file format, font size, font style, image resolution, style of numbering, etc. Adhere to these guidelines before submission.
  • Cite figures in the main text at the appropriate place where the text is supported by a particular figure.

The figures in your research paper communicate a parallel story to the reader. In fact, the reader can derive a fairly good idea of your paper by just scanning the figures in the paper. Remember that figures are not just tools to beautify your text; they are the heart of your research and an intrinsic part of your research paper. This highlights the importance of organizing the figures well so that they are able to perform as an excellent prop for your text.

Research problem: A statement of intent

Research problem: A statement of intent
How do I devise my research problem?

A research problem is a statement based on the area of research, which is the first step in a research process. Devising an appropriate research problem depends on the in-depth knowledge, skills, and expertise of a researcher in their particular subject field. Therefore, a researcher needs to devote considerable time to select a suitable research problem.

Steps to formulate a research problem

There are two essential steps to follow while selection:

  • Identification of a research problem
  • Selection of a broad research topic and narrowing it down to a precise statement.

Sources to derive a research problem

Several factors, both extraneous and intrinsic to the research per se, help the researcher in identifying a research problem. They include the following:

  • Field conditions: The rich experiences in the field provide relevant ideas for developing an apt research problem.
  • Personal experience: This might help generate new ideas for formulating the research problem.
  • Previous related researches and theories, and critical review of the available literature: Relevant questions might crop up in our mind when we evaluate the articles, reports and reviews related to the subject area.
  • Expert advice: Subject matter experts are vastly experienced in the field of study. Hence, they may help the researcher find the current problem related to the research, and even devise a research problem.

What should be the nature of the research problem?

There are several guidelines that need to be followed while selecting a research problem. Your research problem needs to be:

  • An original and unique one.
  • An encapsulation of the nature of research.
  • Feasible vis-a-vis time required for its completion.
  • A realistic statement that can be achieved with the available financial resources.
  • Backed by support from your affiliated institution and peers.
  • Formulated in accordance with ethical considerations.
  • Based on recent or current problems persistent in the field of study.

Types of research problems

Research problems can vary according to the field of study and the scope of the research. Basically, there are three types of research problems:

  • Descriptive
  • Relative
  • Casual

A well-framed and appropriate research problem presents the researcher’s view in a clear and lucid manner, and helps readers understand the purpose of the research better.

Authorship Disputes: Tips to avoid conflicts

Tips to avoid Authorship DisputesAuthorship’ denotes the practice of providing truthful credits for intellectual contributions and innovative concepts. It not only helps authors acquire the credit for the work, but also ensures that they assume responsibility for the research conducted and presented. Moreover, it is perceived as a tool for personal satisfaction, prestige, and especially, a stepping stone in a writer’s academic career. Though the term sounds interesting, it involves high risks and problems in practice.

The Committee on Publication Ethics (COPE) often receives disputes regarding authorship. These cases usually involve disputes like the omission of a deserving junior researcher’s name from the authors’ list or a proposal by a sponsor for including the name of a non-contributing author. However, it also received a shocking complaint from a female author, who said that her name was replaced with that of her boss in the final version when she was away on maternity leave.

Apart from having a direct impact on the publication in question, authorship disputes can also have repercussions on a writer’s fair credit, collegial relationships, future collaborations, and reputations.

Following the adage that prevention is better than cure, the following are some guiding principles to avoid conflicting situations like authorship disputes.

  • Adhere to the authorship criteria of the publication

Each publisher follows specific authorship guidelines enunciated by organizations such as the International Committee of Medical Journal Editors (ICMJE), World Association of Medical Editors (WAME), Council of Science Editors (CSE), Committee on Publication Ethics (COPE), and Good Publication Practice (GPP2). Non-compliance with the concerned guidelines—i.e., unequal application of authorship criteria, granting authorship to undeserving individuals, and/or omitting authorship to deserving individuals—is considered to be a serious offense in the academic world and can be construed as  research misconduct.

  • Hold prior discussions with co-authors

All the authors of a paper should discuss and finalize the authorship order and contributions along with respective responsibilities before beginning to prepare a manuscript and, if possible, even before starting a study.

  • Stick to the plan of action

In few cases, it has been observed that even if the authors have agreed to the sequence of authorship and contributions, fraudulent authors make last-minute changes in the manuscript or research paper just before submission. This leads to conflicts in publishing the paper, and some even end with retraction of the paper. To avoid such anomalies and unpleasant situations, it is advisable to comply with the agreement made between the author and co-authors.

However, even the best plans sometimes fail. So it is better to track and revisit the issues and monitor any changes or modifications in authorship or contributions. If one discovers any changes before publication, it can be revised after discussions with the co-authors. Conversely, if the detection is made post-publication, one can contact the journal along with the written agreements and evidence of contributions, and request for a correction or a retraction of the paper.
