The Significance of Journal Impact Factor in Academic Publishing

Most academics who have published papers in scientific journals are familiar with the term “impact factor.” So, what exactly is impact factor of a journal? Scientific journals are ranked by a metric known as “impact factor.” Thomson Reuters is an academic publisher that has come up with a database of impact factors of journals. Although it is primarily used a library resource, it is also very good to attract papers for publications.

Impact factor is a crucial yet controversial metric in scientific publishing. Based on the impact factor of a journal, scientists decide whether it is suitable to publish their work. The impact factor of a journal is a metric that describes the visibility range of a journal. In general, journals with high impact factor are considered to be prestigious in a particular field.

How did journal impact factor gain significance in academic publishing?  

Academic publishers felt that journals should be ranked according to their impact or significance. To address this concern, they devised a metric known as “journal impact factor.” The impact factor of a journal indicates the patterns and frequency of citations of a journal.

The origins of “Impact Factor” can be dated back to the year 1955. In an issue of the journal Science, Eugene Garfield first expressed the need for a metric that ranks journals on the basis of their impact on research. Eugene Garfield was an information scientist who came up with this idea in 1955.Eugene Garfield worked with Irving Scher, who was her colleague in the field of information sciences. Together, they introduced the metric “impact factor” in the year 1960.

The “journal impact factor” ranked all scientific journals after comparing the difference between their sizes and their network of circulation.  The impact factors of all scientific journals were presented in the form of a database, which was termed as the “Science Citation Index (SCI).” This database was first published by the Institute for Scientific Information. Eugene Garfield was the founder of this institute. Later on, the database was rechristened as “Journal Citation Reports (JCR)” and was published by Thomson Reuters, a well-known academic publisher.

How to determine the impact of a journal, and which journals are associated with it

Eugene Garfield determined the number of citations received by papers published in a scientific journal over a span of two years. Then, Eugene Garfield divided this number with the total number of papers that were published in that particular journal over a time period of two years.

As research is carried out at a different pace in different fields of study, Eugene Garfield compared a journal with other journals of the same field. In other words, a medical journal was compared with other medical journals. Similarly, a journal on ecology was grouped with other journals of ecology.

Although impact factor largely depends on a journal, it is also affected by the research conducted in a field of study. In the year 2009, the impact factor 87.925 was the highest for a scientific journal. However, the next highest impact factor was only 50. Thus, the field of study and the related research work significantly affects the impact factor of a journal.

Every two years, JCR is published by Thomson Reuters in the month of June. For example, the database published in 2016 presents the journal impact factors for the time period of 2014-2015. About 9000 journals were included in the JCR database of 2009. However, this database includes only 25% of all the published journals. Moreover, it mainly comprises of journals in English language.

Why it is necessary to know about a journal’s impact factor

According to Eugene Garfield, impact factor is a metric that reflects a journal’s prestige in the scientific community. Scientists often see the journal’s impact factor to decide whether it is suitable for publication. By publishing their papers in scientific journals of high impact factor, scientists can gain more respect in their community. Moreover, they also gain other benefits, such as better access to research funding, an extension of tenure, recruitment to prestigious institutions, and promotions at universities. Nevertheless, journal impact factor cannot be considered as a sole criterion for the integrity of a journal or a research study.

The editors of journals always make an effort to increase the impact factor of their journals. Sometimes, these editors request authors to increase citations in the papers submitted for publication in their journal. This is an unethical practice and should not be conceded at all costs. The impact factor of a journal is a metric used in information sciences: it does not govern the quality of a research work.

The controversies and problems of journal impact factor 

The journal impact factor’s indiscriminate use in academic employment industry has been severely criticized by many information scientists, including Garfield. The significance of an author’s research work cannot be solely estimated from the journal’s impact factor. Impact factor should always be considered along with other parameters of evaluation, such as the peer review process.

It should be noted that smaller fields of study attract lesser citations, so the journals of these niche fields have lower impact factor. These journals may contain papers of path-breaking research work. The impact factor of a journal should always be compared with that of a journal in the same field of study. The impact factor of a journal is not really an indication of the significance of a research work.

At this stage, it is also necessary to point out the problem associated with prestigious journals. Because these journals have a high impact factor, it is really very difficult to publish papers. This is because the rejection rate of such journals can be as high as 75%. Remember, the main aim of a researcher is to get their work published in a peer reviewed journal. Therefore, researchers must not just limit their efforts to high impact journals. They should consider all other factors while deciding which journal is most suitable for their work.

Which metrics can be considered as good alternatives to journal impact factor?

Since the significance of impact factor has been very controversial, researchers are advised to use other alternative metrics, such as SCImago Journal & Country Rank, the h index, Scopus, and the Eigenfactor. In the year 2005, Jorge Hirsch was a physicist who developed the h index. This metric compared the author’s total number of published papers with the number of citations received by those published papers. In other words, it evaluated the productivity of an author in academia.

The Web of Science is an index that uses the metric Eigenfactor. This metric measures the frequency of citation of a published paper over a period of five years. It thus determines how influential the article is in a particular field of study.In the metric The SCImago Journal & Country Rank, a database of journals was provided. This database was based on the rankings and the visibility received by journals, which were further organized according to their types. It comprehensively covered all international publications. Scopus is a database based on abstracts and citations. This database is published by the noted scientific publisher, namely, Elsevier.

 How should journal impact factor be used by researchers in academia?

Although journal impact factor is an important metric to be considered before publishing a paper in a scientific journal, it should never be considered as the sole criterion for evaluating the quality of a journal. The decision to submit and publish a paper should never be made on the basis of the journal’s impact factor. It is always essential to assess the scope and objectives of a journal and then determine the possibility of your paper getting published in that journal. Harrisco is a company that provides complete publication support to authors and can help authors in journal selection, peer review, language editing, and translation. Harrisco is a name to reckon with in the academic publishing industry as it has been in business since 1997.

 

Effective Tips for Dissertation Writing

Pursuing a doctoral program in science and technology requires at least 3-4 years of rigorous work in a laboratory. A dissertation summarizes the research project that was carried out for three to four years.

Defending the dissertation is the important aspect of receiving a Ph.D. A researcher is entitled Ph.D. only after successfully defending the dissertation. It is an important landmark in the career of a researcher who can now be called an independent researcher or scientist.

Having said that, not all scientists are great wordsmith and a poorly written dissertation may be a death knell to one’s career. In fact, a researcher may not be able to receive Ph.D. if the dissertation is poorly written.

In this article, we explain steps that must be followed to write a dissertation effectively.

1. Start writing the dissertation right from the beginning of the research program: Most doctoral students tend to think that dissertation must be written at the final stage of their doctoral program.

They consider dissertation as just a scholarly paper that can be “written up” once the experimental study of their doctoral program is completed. They consider research experiments as the “real work” and scholarly communication as completely secondary.

Most doctoral students of science and technology are engrossed with work in the laboratory. They have to design the experimental study, perform complex experimental procedures, perform statistical analysis, derive results and finally present conclusion. With this rigorous work in the laboratory, most doctorate students procrastinate “dissertation writing.”

Although writing and defending thesis is the last component of a Ph.D program, science students should start writing their thesis/dissertation right from the start of their doctoral program. This is because the doctoral program extends for uptill three years and thesis must a cumulative reflection of their entire period. It is not something that can be “written up” at the fag end of the doctorate program.  

Dissertation writing rightly reflects the “art of science” as it is a skill that requires scientists to hone their skills as wordsmiths in science communications.  Every paper and presentation written from the first day of the doctoral program is important; doctorate students should start preparing their thesis from the very first day of their graduate careers.

2) Spend some time each on writing dissertation: It is essential that all doctorate students hone their skills in science writing. Therefore, science writing must be a part of your routine. There are many resources and style guides of science writing. Each doctoral student must spend some time daily reading these resources in order to get a grasp of science writing.

3) Consult your advisor throughout the process of dissertation writing: To pursue Ph.D. program successfully, it is very essential to have a rapport with the supervisor. It is essential to have an effective communication with your supervisor while pursuing your Ph.D.. This will certainly help a doctoral student in completing their dissertation in a timely manner. Most doctorate students feel afraid to show the rough draft of their thesis to the supervisor. Such an attitude can prove to be “fatal” in dissertation writing.

It is very important to communicate with the supervisor on a daily basis. Always seek advice on the progress of your work while pursuing your doctoral program. Professors and mentors would always help in different aspects of thesis writing, not just in terms of English language but also in refining the scientific aspect of this study.

If the student has a poor rapport with the supervisor, then it becomes very difficult for the student to defend their thesis at the fag end of their doctoral programs. Quite a few times, their dissertation is rejected as the supervisor is not just aware of the student’s research work right from the beginning. Following the rejection of dissertation, the student is crest-fallen as it is back to square one or ground zero for the student.

4) Students must maintain an annotated bibliography: This is a very important strategy for writing an effective dissertation. This strategy must be followed by a researcher throughout their career. Apart from compiling a conventional reference list of different papers, students must prepare an annotated bibliography that includes personal reading notes on each paper that they have read.

While writing a formal paper, a researcher must compile annotated bibliographies relevant to the topic. These may be personal reading notes obtained from several projects that serve as an interactive background for the current work in progress. Commentary, updates, and references are some of the kinds of additional writing that must be incorporated into a formal paper meant for publication in scholarly journals.

5) Students must consider “stepping stone” assignments:

Most PhD thesis of scientific disciplines contain “Introduction” and “Discussion”  sections in which previously published papers are referenced and quoted for arguments and evidences. Published papers are the resources on which the dissertation of the current study has to be based. Therefore, science students must write evaluative reports of all experiments periodically. It is important to write about failures and obstacles as they can be then included in the discussion section of the formal paper.

Apart from published papers, students may also refer to meta-analyses, literature reviews for referencing. A book review may also prove to a good resource in rare cases. New methodologies and techniques should also be evaluated periodically. All these types of scientific literature are very useful in writing a dissertation paper.

6) Attend workshops, conferences, and seminars: Students must present their research work at any relevant academic workshop, be it conference or less formal meetings of graduate students. When students make presentations at these events, they receive constructive feedback in improving the quality of the final draft of the dissertation.

Many universities hold formal meetings of students who are in similar stages of their doctoral programs. At these meetings, students discuss and review each other’s work to improve the quality of their work. It is highly recommended that students join such writing groups and workshops, wherein fellow students offer feedback and proofreading services.
