AI beats doctors in predicting heart diseases

newscapsule_27_02_19

A research team at Imperial College London and the Medical Research Council has finally been able to use Artificial intelligence to forecast outcomes for heart patients, aiding doctors to find the best treatment for individual patients. The technology outperformed doctors, being able to correctly predict a patient’s diagnosis 75% of the time. It is hoped that the new technology will assist doctors to spot clinically useful information from heart scans that would be missed by a human eye enabling them to take an action at the earlier stage.

Top doctors of US aren’t disclosing their drug company ties

newscapsule_20_02_19

A noteworthy fraction of the topmost doctors fail to reveal their financial relationship with the drug companies in the guidelines. A massive research investigation in the United States found a link between marketing payments to doctors and local deaths from opioids. It was found that only one-third of the guideline writers had a potential relevant tie to a drug company and the rest was not disclosed. This is a huge matter of concern as the guidelines put big impacts on the sort of care a patient receives from doctor, and on which drugs they prescribe.

Government declares hike in Research scholar stipend. Scholars disappointed

newscapsule_14_02_19

After continuous protests claiming modification of stipends for research scholars, the government finally announced a hike in the monthly payments of the research fellows. Junior research fellows will now get Rs 31,000 p.m. and Senior research fellows will get 35,000 p.m., a hike of roughly 20%. Stipends for Research Assistants would now range from Rs 47,000 to Rs 54,000 p.m. This is the lowest increase in stipends since 2010. The research scholars are apparently disappointed with the sanctioned hike and have said that they would continue their ongoing protest against the insignificant increase in stipends.

Pyoderma gangrenosum

Pyoderma gangrenosum (PG) is an immune-mediated, rare ulcerative disease of the skin. In general it occurs in a genetically susceptible individual. Its incidence ranges from 0.3-1.0/100,000 population. Female are affected more than males.

The cause of PG is not clear but it is attributed that the aberrant chemotaxis of neutrophil to the site of trauma causes development of  primary lesion.

The primary lesions   are usually small tender papule, pustule, folliculitis or nodule, which breakdown rapidly and progress to a large painful ulcer. The PG ulcer is characterized by violaceous undermined edges, and necrotic  floor covered with purulent exudate and associated disproportionate pain. Rarely it may be non-tender. The ulcers last for months to years. The PG has the fluctuating course and it may deveop pathergy and lead to rapid enlargement of the disease.

There is no definite investigations to diagnose PG. To date, diagnosis of PG is by exclusion of other causes of ulcers, associated systemic diseases, correlation of histology with clinical feature or rapid response to high dose corticosteroid.

Treatment with Corticosteroid is satisfactory; cytotoxic drugs are rarely added for treatment of PG. The lesions usually heal with cribriform scar. Recurrence of this disease may occur.

The patient with diagnosis of PG are advised to avoid surgical procedure for the fear of recurrence through pathergy, but when surgery is required, the surgery should  be carried out  under the supersvion of Dermatologist for atleast 2-3 weeks after surgery to prevent pathergy.

MLA Style Formatting

In every field of research, there is a need to borrow facts or figures from other scholarly studies. Based on the requirement, the conventions used in various papers may vary. The MLA style follows a set of guidelines set by the Modern Language Association. This style is widely used in the field of humanities, especially in English, philosophy, foreign languages, and religious studies. High school and college writing assignments mostly follow this standardized writing style. Generally, MLA style of formatting is considered to be simpler and more concise compared to other styles.

Basic Guidelines for MLA Style of Formatting

  • The standard 8.5 x 11-inch paper should be always used.
  • Set a margin of 1-inch on all sides of the document.
  • Give an indent of half inch/5 spaces (or you can give a tab) for the first line of each paragraph. Do not give extra space between the paragraphs.
  • The entire text should be double-spaced.
  • Use a clear font, such as Times New Roman and the point size should be 10-12 point.
  • All the pages should be numbered (in some cases, there might be specific instructions not to number the first page). Place the page numbers on the top right-hand corner of the page and align them flush right. Your last name must precede the page number.
  • The title should be centered. Do not give extra space above or below the title of your paper.
  • You need not set a separate title page unless specified.
  • Do not use boldface in an MLA paper unless specified.
  • In case of a quoted sentence, punctuation (a period or comma) should be placed inside the quotation marks.
  • Endnotes, if any, should be set on a separate page just before the ‘Works Cited’ page.

These basic guidelines are provided just to give you an outline idea about the structure of the MLA style of formatting. For further details, you can refer to the MLA Handbook and the MLA Style Manual.

Guidelines for Writing Scientific Article

Good design and simple writing style of a scientific article are very important for getting the work published in a scientific journal. Nowadays, all are busy in their work; they need something that is easy to read and understand quickly. Therefore, it is effective to write a scientific article in a clear and simple way, with as much information as can be provided in a straight-forward and concise style. Following are described the guidelines for writing scientific article in an effective manner.

Effective Guidelines for Writing Scientific Article

Writing the Abstract

  • Abstract is the brief report of the whole article. It should highlight the major and important points covered in the article.
  • Writing the abstract includes summarizing the whole article while providing as much information as possible.
  • Identify the chief objectives, results, discussions and conclusions, and gather them in a single paragraph.
  • Exclude background information, literature review, account of methods, and extra words and phrases.
  • Re-read and revise the abstract to ensure that it conveys only the vital information.

Developing the Outline

  • The idea of an outline is to separate and arrange the topics and arguments of the whole article into smaller tasks in a logical form before writing the final article.
  • Prepare a fundamental message of the article by summarising the paper in one sentence (20-25 words).
  • Describe the sampling method employed and the materials and methods used to conduct the study.
  • Identify the major results and findings. List them in note form.
  • Define the chief conclusions and implications arising from the study.
  • Identify the limitations of the study results. What changes in practice, approaches or techniques would you recommend.
  • List every key point separately. Organize them chronologically by order of importance. Organising method should be plain and coherent.
  • Identify the references pertaining to each and every key point.
  • Prepare the introduction by reading the notes made in the outline. Introduction should begin with the main message, describing the purpose/objective of the study, how the study was conducted, what were the results and their implications.

Preparing the First Draft of Article

  • Combine all the information, i.e., data, references, tables, figures, etc.
  • Decide the journal to which you plan to submit the article. Write and format the article according to the targeted journal.
  • While writing the first draft, include all the chief points and information. Ignore the incomplete sentences and incorrect grammar at this stage.
  • Express yourself clearly through your writing by writing what you understand and how you understand it.
  • Use the headings from the prepared outline. Attempt to write the article in parts. Treat each section as a short article.
  • Take a break from the work. Read the prepared first draft with a fresh approach and viewpoint.
  • Edit or modify or delete, but be prepared to revise the article several times to make the final draft.
  • Wherever possible and applicable, use short sentences, simple and clear words and phrases, small paragraphs denoting single idea.
  • Proofread for clarity and readability. Re-read sentences and paragraphs for lucidity. For a scientific article, paragraphs of about 150 words in length are considered most favorable.
  • Ensure consistency and regularity. An article with more than one author often shares the writing procedures. However, the writing style should be consistent and regular.

The above mentioned guidelines for writing scientific article provide the most basic and common guidelines used while writing any scientific article. By following these guidelines for writing scientific article, one can learn and know how to write scientific articles in an effective and attractive manner.

Major Sections

While formatting research paper in APA style, the sections should be arranged in proper order: Title page, Abstract, Main Body, References, Appendixes, Tables, Figure Captions, Figures.

However, the major sections include: Title Page, Abstract, Main Body, References.

Running Head

Running head is a short version of the paper’s full title, which is helpful for readers to spot the titles for published articles. Running head’s title should be in CAPITAL letters and within 50 characters (including spaces and punctuation). The running head should be present in each page, with the title “Running head” mentioned only on the title page, and not in the rest of the paper. The title should be left aligned, and page numbers right aligned.

Title Page

Title page should be the first page of manuscript, enlisting the title of the paper, author’s name and institutional affiliation, without mentioning titles (Dr.) or degrees (PhD). APA formatting suggests that the title should be centre aligned and positioned in the upper half of the page. Besides, it should be limited to 12 words in length, without any abbreviations or trivial words, and should not be bolded, underlined, or italicised.

Author note

Author’s note provides the general information about the authors involved in the research. It includes the author’s departmental and institutional affiliation, changes in affiliation (if any), acknowledgments, funding sources, special circumstances and contact information, like postal address or e-mail.

Abstract and Keywords

Abstract should present a very clear and concise summary of the whole research paper. It helps the readers to swiftly assess the main idea and purpose of the research. Abstract should be limited to 150-250 words, with all acronyms and abbreviations defined properly.

A list of selected keywords should be provided in the abstract section, helping researchers to find your work in databases. The title “Keywords” should be italicised, and the sentence should be indented like the rest of the paper.

References

References provide the information needed to find any cited source. All in-text citations should be provided in the reference list. Reference list should be arranged in alphabetical order by the author’s last name, or the first word in citation. All names should be cited for less than six authors, while for six or more authors, the first author’s name is followed by “et al.”. In-text citations (direct quotes) should mention author(s)’s name, publication year, and page number(s).

Tables and Figures

Each table should start on a new page. The table title and caption should be left aligned, while only the table caption should be italicised.

Figures captions should be provided separately on a new page. The figure label should be italicised and not the figure caption. Each figure should start on a new page, provided at the end of the paper.

Appendices

Appendices are short contents that complement the research paper, but are not directly related to the text. Usually, appendices are mentioned in the body of the paper. In case of more than one appendix, use a capital letter, like Appendix A, Appendix B, etc., to identify them separately.

Above mentioned guidelines will help you to learn and get familiar with formatting research paper in APA style. However, it would be suggested to seek guidance from your instructor for his final word on the format and style needed to format the assigned paper.

Scale Classification Bases

Scale Classification Bases

The Scale Classification Bases can be categorized on the following bases.

  1. Subject orientation: In this, a scale is designed to measure the characteristics of the respondent who completes it or to estimate the stimulus object that is presented to the respondent.
  2. Response form: In this, the scales can be classified as categorical or comparative. Categorical scales (rating scales) are used when a respondent scores some object without direct reference to other objects. Comparative scales (ranking scales) are used when the respondent is asked to compare two or more objects.
  3. Degree of subjectivity: In this, the scale data is based on whether we measure subjective personal preferences or just make non-preference judgements. In the former case, the respondent is asked to select which person or solution he favors to be employed, whereas in the latter case he is simply asked to judge which person or solution will be more effective without reflecting any personal preference.
  4.  Scale properties: In this, the scales can be classified as nominal, ordinal, interval and ratio scales. Nominal scales merely classify without indicating order, distance or unique origin. Ordinal scales indicate magnitude relationships of ‘more than’ or ‘less than’, but indicate no distance or unique origin. Interval scales have both order and distance values, but no unique origin. Whereas, ratio scales possess all these features.
  5. Number of dimensions: In this, the scales are classified as ‘uni-dimensional’ or ‘multi-dimensional’. In the former, only one attribute of the respondent or object is measured, whereas multi-dimensional scaling recognizes that an object might be described better by using the concept of an attribute space of ‘n’ dimensions, rather than a single-dimension continuum.
  6. Scale construction techniques: This can be developed by the following five techniques.
  • Arbitrary approach: In this, the scales are developed on ad hoc basis. It is the most widely used approach.
  • Consensus approach: In this, a panel of judges evaluates the items chosen for inclusion in the instrument regarding whether they are relevant to the topic area and unambiguous in implication.
  • Item analysis approach: In this, a number of individual items are developed into a test that is given to a group of respondents. Post administering the test, total scores are evaluated, and the individual items are analyzed to determine which items discriminate between persons or objects with high and low total scores.
  • Cumulative scales: These are chosen on the basis of their conforming to some ranking of items with ascending and descending discriminating power.
  • Factor scales: This can be constructed on the basis of inter-correlations of items indicating a common factor accounts for the relationship between items.
