The Ugly Side of the Journal Impact Factor

 :: Posted by American Biotechnologist on 05-16-2013

Are you obsessed with publishing in high ranking journals such as Cell or Science? Do you gloss over your works that have been published in low ranked journals when talking with colleagues or attending a job interview? If the answer is yes, you are not alone.

Since its invention approximately 60 years ago, the Journal Impact Factor (JIF) has been used to assess the quality of academic literature and the influence of scientific papers on the scientific community. The JIF was proposed by Eugene Garfield in the early 1950s and originally published by his Institute for Scientific Information (ISI) as a subscription buying tool for academic and medical librarians. The JIF assigns a score to scientific journals based on the average number of citations received in a year per paper published in the journal during the two preceding years. It has since become the authority on which journals are considered top tier publications are therefore premiere space for scientists wishing to best publicize their work and gain notoriety.

Unfortunately, the JIF has also become a tool used to ascertain a scientist’s worth and can often be a determining factor in the levels of funding they are to receive. This is an unfortunate turn of events since the JIF contains many deficiencies such as glossing over differences between fields, and lumping primary research articles in with much more easily cited review articles. As such, researchers that publish quality work in lower ranked journals are often at a disadvantage compared to those publishing secondary research in higher ranking journals.

In order to “protest” and counter this phenomenon, a group of publishers from both high impact and low impact journals have formed the Declaration on Research Assessment (DORA) which aims to lower the influence of the JIF on assessing scientific merit.

Dora has released 18 principles which are geared towards accomplishing these goals. Some of the recommendations that stand out the most include:

  • JIF should not be used to measure quality of individual articles or to asses an individual scientist’s contributions, or in hiring, promotion or funding decisions
  • Funding agencies should place more weight on the scientific content of a paper than its JIF
  • Scientific content of a paper should be considered a more important hiring decision than the JIF
  • A call for organizations to be open and transparent by providing data and methods used to calculate all metrics
  • Researchers should challenge research assessment practices that rely inappropriately on JIF

High School Students Saving the California Redwoods

Ray Cinti
Convent of the Sacred
Heart High School

A conversation about South American frogs started Ray Cinti on the road to a new way of teaching high school biology. Cinti had always taken his students from Convent of the Sacred Heart High School in San Francisco to Muir Woods National Monument, north of the city, where they learned the basics of redwood ecology. However, he had recently been wondering if his students might conduct more meaningful research in this preserve. Then he happened to speak to a researcher at the University of San Francisco, and a light bulb lit up for him.

Mapping the embryonic epigenome

 :: Posted by American Biotechnologist on 05-09-2013

A large, multi-institutional research team involved in the NIH Epigenome Roadmap Project has published a sweeping analysis in the current issue of the journal Cell of how genes are turned on and off to direct early human development. Led by Bing Ren of the Ludwig Institute for Cancer Research, Joseph Ecker of The Salk Institute for Biological Studies and James Thomson of the Morgridge Institute for Research, the scientists also describe novel genetic phenomena likely to play a pivotal role not only in the genesis of the embryo, but that of cancer as well. Their publicly available data, the result of more than four years of experimentation and analysis, will contribute significantly to virtually every subfield of the biomedical sciences.

After an egg has been fertilized, it divides repeatedly to give rise to every cell in the human body—from the patrolling immune cell to the pulsing neuron. Each functionally distinct generation of cells subsequently differentiates itself from its predecessors in the developing embryo by expressing only a selection of its full complement of genes, while actively suppressing others. “By applying large-scale genomics technologies,” explains Bing Ren, PhD, Ludwig Institute member and a professor in the Department of Cellular and Molecular Medicine at the UC San Diego School of Medicine, “we could explore how genes across the genome are turned on and off as embryonic cells and their descendant lineages choose their fates, determining which parts of the body they would generate.”
