Types of Journal ArticlesA journal is a periodical publication in which research papers related to a particular academic discipline are published.  Scholars publish journal articles to showcase their research, get evaluations fr|om academic circles, and facilitate further discourse on the topic. As a platform for scholars to share and exchange knowledge, academic journals are treasure troves of in-depth knowledge ranging fr|om science to arts. Meticulous planning and writing can feel overwhelming when writing a journal article for the first time. However, this is a painful but rewarding process of training that everyone goes through as a scholar and in the end, the results of all your hard work are permanently recorded under your name.   Research articles, review articles, and commentary articles are the most common types of journal articles you will encounter.   Research Article A research article sets forth hypotheses and questions directly derived fr|om those hypotheses, describes the process of testing and finding answers to the research questions, and details research findings. Research articles are mainly published in scientific disciplines. They walk the reader through the author’s process of testing hypotheses and finding answers to research questions. The materials, tools, and methods employed in the study should be explained in detail. A research article chronicles research results and new findings, and discusses the implications thereof.   Review Articles Review articles describe various papers published in academic journals, and provide updates on recent developments and future prospects related to the particular academic discipline and topic. While review articles discuss recent developments and discoveries made by different scholars researching the subject, they also deal with controversies that have emerged, fields and topics that have yet to be studied, and new ideas.   Commentary Articles A commentary article is an article that expresses a personal opinion or point of view about a research paper written on a particular topic. Although journals that publish research articles reporting major findings rarely designate and commission authors with expertise, commentaries on recently published articles dealing with topics that may be of interest to multiple scholars are sometimes published in other academic journals.     Note Various academic journals fr|om different fields publish journal articles on a regular basis. Some academic journals publish research articles, review articles, and commentary articles, while some are dedicated only to review articles. Each journal publishes articles with different depths and ranges of research. In most cases, the required number of words, figures and tables, and references are determined according to the type of the article. In addition, each journal designates a specific bibliography format. Submissions are reviewed and commented on by two to four reviewers, who are scholars handpicked by editors who are experts in the field, and after that the author will revise his/her article. The editors carry out an exhaustive review of the content and decide whether or not to publish the article. During the revision process, scholars will often conduct additional research and add new findings, which means articles will often times be revised at least twice. 

How to Write a Cover LetterWhat is a cover letter? A cover letter typically has three to four paragraphs and is addressed to your potential employer.  It describes why you are interested in the position, the company, (or the academic program), and why you'd be a good fit for it.  It is typically included in your application together with your résumé. You would need to highlight your accomplishments, experiences, and skills that are pertinent to the position you're seeking.  In contrast to a resume, a cover letter lets you talk about your career experiences more in detail and discuss why you are the right person for the job.  A good cover letter allows you to give employers a good impression and makes you stand out among the applicants.     What to consider before you write Before you start your cover letter, collect all the information you may need.  Here are some things that you need to consider before writing a cover letter:   ONE. In terms of talents, skills or accomplishments, what are some of the specific things that you would like to let your employers know?   TWO. How were you made aware of the employment possibility?  Note the name and position of the person if you discovered it through a personal connection.  Or, if you discovered it via an advertisement or job board, write down where, when, and any specific instructions included in the job description.   THREE. Why were you drawn to the company that you are writing to?   FOUR. Think about who you are writing to.  If it's a specific person, address them by name and title. If not, consider addressing one of the followings: “Dear Name of the Title" or "Dear Name of the Department.”     How to format a cover letter? ㆍPage : A maximum of one page ㆍFont : Arial, Calibri, or Times New Roman ㆍSize : 10 to 12 points ㆍMargin and Spacing : One-inch margins and single spacing     A cover letter should have the following sections like the way a business letter is formatted:   ㆍHeader with date and contact information Add personal and information related to the position at the top of your cover letter, just like you would with any conventional business letter header.  Doing so makes it simpler for a hiring manager or recruiter to get in touch with you. Your name and address can also be centered at the top of the page just like they are on your resume.  Your name and address can also be centered at the top of the page, just like they are on your resume.
