Dr. Rubén Urbizagástegui Published in a Peer Review Journal

The paper with the title of “El Crecimiento de la lietartura sobre la Ley de Bradford” [Growth of Literature on Bradford’s Law] has been published in: Investigación Bibliotecológica: Archivonomía, Bibliotecología e Información, Volume 30, Issue 68, pages 51-72, January-April 2016. This is an academic peer review journal, indexed by Web of Knowledge, Scopus, JSTOR and others. The journal editor is the Instituto de Investigaciones Bibliotecológicas y de la Información, Universidad Nacional Autónoma de México (IBI/UNAM).

Samuel Clemente Bradford was a British mathematician who around the 1930s became a librarian for the Science Museum in London. Bradford is known for a principle that lies behind the development of the Web of Knowledge, Scopus, and JSTOR collections, which cherry pick the leading journals in each field. In the 1970s Bradford’s statement become known as “Bradford’s law” which behaves very similar to the Pareto Principle. The Pareto Principle states that a small number of causes is responsible for most of the effects or reactions, usually a 20% to 80% ratio. Later this relationship became known as the 80/20 rule or sometimes the 70/30 rule. In a library setting, 20% of the items in the library collection is responsible for 80% of the circulation.

Bradford’s law was heavily used to identify libraries’ core collections. Despite the profusion of publications, no research was done to follow upon the growth of the literature on Bradford’s law. This is why Rubén Urbizagástegui, a librarian at the Metadata Department at UC Riverside, began following the publications on Braford’s law and recently published a paper titled “Growth of the Literature on Bradford’s Distribution.” His paper analyzes the literature produced on Bradford’s law from 1934 to 2012. The study identified 936 documents produced by 1,123 authors, working in sixteen different languages, with English as the leading language of the publications, followed by Chinese, Spanish and Portuguese. The study reveals also that the fifteen most productive authors typically publish in English, in an academic journals, and present their findings in national conferences.

University and Community Members Talk Sustainability at UCR Carbon Slam

Transforming ideas about clean energy into real technologies was the topic of UC Riverside’s first ‘Carbon Slam,’ a community event held Thursday, May 19 in the Bourns College of Engineering’s Winston Ching Hall.

Mihri Ozkan, professor of electrical engineering, organized the event as part of her role as UCR’s Faculty Climate Action Champion. About 50 people from the campus and Riverside community attended to hear the presentations and participate in the discussions.

“I wanted to organize this event as a conversation between people from the university, the City of Riverside, and the federal level to figure out how we can work together to meet our common goals of increasing sustainability and reducing carbon pollution,” Ozkan said.

The keynote speaker was Eric A. Rohlfing, deputy director for technology at the Advanced Research Projects Agency—Energy (ARPA-E), a U.S. Department of Energy initiative formed in 2007 to support researchers who are developing new ways to generate, store and use energy.

Rohlfing highlighted how ARPA-E helps start-ups and university research teams as they turn concepts into tangible prototypes that can attract private sector investment.

Other speakers included Riverside Mayor Rusty Bailey, Andrew Markis, a sustainability officer for the City of Riverside, and John Cook director of sustainability at UCR. Four students, who were chosen alongside Ozkan as Climate Action Fellows, presented short talks about their work on campus ahead of their participation in a UC-wide Carbon Slam that took place May 23 in Palo Alto.

Professor Studies HPV and HIV in Peruvian Transgender Women

Latin American transgender women are highly vulnerable to HIV and HPV infection, a study appearing in Transgender Health reports.

“Our study, done in Peru, investigated anogenital human papilloma virus or HPV and cumulative HIV incidence among 68 initially HIV uninfected Peruvian transgender women,” said Brandon Brown, an assistant professor of social medicine and population health in the School of Medicine, who led the two-year research project.  “Anogenital warts were common among transgender women in our sample.  The overwhelming majority – nearly 96 percent – had at least one anogenital HPV genotype.  Six percent of the participants became infected with HIV over the course of the study.”

The study is the first to test an association between anogenital warts and HIV incidence among transgender women.  According to Brown and the coauthors on the study, HPV infection is strongly linked to subsequent infection with HIV, with those previously infected with HPV nearly doubling their risk of acquiring HIV infection.

“We found that more than half of the transgender women in our study were infected with high-risk HPV types,” Brown said.  “These women could have greatly benefited from immunization before exposure, but few HPV vaccine recommendations exist for transgender women anywhere in the world.”

The research project used only those participants who identified as a gender different from male.  Only about one third of the participants had heard of HPV before participating in the study.  To take part in the study all participants needed to be HIV uninfected at the time of enrollment.

“It cannot be stressed more that vaccination and education are key to reducing HPV transmission,” Brown said.  “The high rates of HPV infection among transgender women in our study may be linked to less than 100 percent condom use, the frequency of anal intercourse, and potential exposure to a variety of HPV genotypes.”

He was joined in the study by researchers in Lima, Peru; Rowan University, NJ; Johns Hopkins University, Md.; and UCLA.
