Impact Factor Distortions

Impact Factor Distortions | English Language Learning and Teaching | Scoop.it

The impact factor, a number calculated annually for each scientific journal based on the average number of times its articles have been referenced in other articles, was never intended to be used to evaluate individual scientists, but rather as a measure of journal quality. However, it has been increasingly misused in this way, with scientists now being ranked by weighting each of their publications according to the impact factor of the journal in which it appeared. For this reason, I have seen curricula vitae in which a scientist annotates each of his or her publications with its journal impact factor listed to three significant decimal places (for example, 11.345). And in some nations, publication in a journal with an impact factor below 5.0 is officially of zero value. As frequently pointed out by leading scientists, this impact factor mania makes no sense.

 

The misuse of the journal impact factor is highly destructive, inviting a gaming of the metric that can bias journals against publishing important papers in fields (such as social sciences and ecology) that are much less cited than others (such as biomedicine). And it wastes the time of scientists by overloading highly cited journals such as Science with inappropriate submissions from researchers who are desperate to gain points from their evaluators.

Citations to highly-cited researchers by their co-authors and their self-citations: How these factors affect highly-cited researchers' h-index in Scopus

Citations to highly-cited researchers by their co-authors and their self-citations: How these factors affect highly-cited researchers' h-index in Scopus | English Language Learning and Teaching | Scoop.it

The h-index is one of the recent indicators in the field of scientometric which introduced by Jorge Hirsch and measures both the productivity and impact of scholars' work. It has been widely used to show the relevance of the research work of prominent scholars. But, does h-index really show this relevance? The purpose of this study is to investigate the frequency of citations to highly-cited researchers by their co-authors, as well as to quantify the weight of self-citations of highly-cited researchers' in three fields of science: clinical medicine, computer science, and economics & business. Finally, the researchers seek to evaluate the impact of these two elements on their h-index in the Scopus database. In this research, highly-cited researchers were selected from the three fields via HighlyCited.com. The study population includes 999 highly-cited researchers in these three fields (280 authors in clinical medicine, 373 authors in computer science, and 346 authors in economics & business). The results show that the average rate of self-citations and co-author citations in clinical medicine is more than computer science, and in computer science is more than economics & business. The results show that there is a positive correlation between self-citation and total citations (P

Times Higher Education - Use of Turnitin software does not deter cheating, study finds

Students who are aware that their work will be checked by plagiarism-detection software are just as likely to cheat as those who are not, a study suggests.

Turnitin software, which is used by thousands of universities worldwide, extracts text from submitted essays and checks it against other sources, such as online documents.

However, the study conducted by a researcher at California State University suggests that such measures should not be regarded as a "silver bullet" in the battle against "deviant" academic practices.

Making research count: applying H-indexes within and between disciplines to analyse publishing cultures

Conclusions:

This paper demonstrates that it is possible both to examine H-index scores within disciplines, and to  create discipline-normalized H-indexes for interdisciplinary comparisons. The same approach can be applied to other bibliometric measures and be used to improve comparative metrics.

 

This is especially important for several common types of bibliometric comparisons. The first is international rankings, such as the Shanghai Jiao Tong Academic Ranking of World Universities (ARWU, or Shanghai Rankings, as it is colloquially known). In the 2011 edition, 20% of this ranking was determined by research output. This was measured by number of papers cited in Nature and Science, and papers indexed in Science Citation Index-expanded, and Social Science Citation Index (which were given double the weight of papers indexed in Science Citation Index-expanded). Another 20% was determined by “highly cited researchers in 21 broad subject categories.”20 The absence of discipline-normalization means that this ranking does not control for publication cultures and the biases that they can generate. As a consequence, institutions with more faculty members in highly productive disciplines have an advantage. This issue is not unique to ARWU – while some ranking systems break out their comparisons by field of study, none to date have implemented valid discipline-normalization.

 

Secondly, comparisons within institutions can be strengthened by discipline normalization. When institutions assess the relative performance of academic departments or units, often as part of unit
review processes, using accurate discipline-normalization to control for publication culture provides a more valid comparison.

 

Lastly, bibliometrics are increasingly applied to hiring decisions within universities. When candidates’ fields of study differ (as would be the case for a dean of science, for example), discipline normalization helps to ensure that the hiring committee understands differences in publication records (and corresponding H-indexes) in the context of differences in publication cultures.

 

It’s time for applications of bibliometrics to become more sensitive to publication culture. Just as importantly, users of bibliometrics need to be aware of the dramatic biases that publication culture can generate. We hope that this paper inspires both scholars and professionals to use accurate and normalized measures when applying bibliometrics to their research, assessment, and decision-making activities.
