Proposed in 2005 by Jorge E. Hirsch, a physicist at the University of California, San Diego, the h-index quantifies scientific output as a single statistic based on both the number and impact of a researcher’s publications.1 An h-index of 40 means that a scientist has published 40 papers that each have at least 40 citations. The h-index conveys the broad impact of work over time and never decreases. It is supposed to be insensitive to the extremes of either non-cited papers or “one-hit wonders.” Authors with similar h-index values are theoretically comparable in overall scientific influence, even if their numbers of papers or citations are very different.
The Health Sciences Library System (HSLS) is pleased to announce expanded library service at the new Children’s Hospital of Pittsburgh (CHP) of UPMC in Lawrenceville. Located on the sixth floor of the hospital in the center of family and clinical activity, the bright and spacious Family Resource Center includes separate areas for the Moulis Children’s, Young Adult, and Family Health Libraries as well as the Blaxter Medical Library.
Like most other programs in the University and the health center, HSLS has been adversely affected by the ongoing global economic crisis. Budget support has declined, leading to difficult decisions about collections and services.
Which Health Sciences Library System (HSLS) users are accessing e-books—students, faculty, or clinicians? Do they prefer print or electronic for specific types of books? How should HSLS allocate its financial resources between print books and e-books?
At this year’s annual Medical Library Association conference, we reported on the results of our study which examined the type of evidence used to support content in some commonly used Point of Care (POC) products. The five POC products included in the study were UpToDate, Clinical Evidence, ACP PIER, DynaMed, and FIRSTConsult. The references from four topical monographs—hypertension, hyperlipidemia, carbon monoxide poisoning, and asthma—were analyzed in each POC product. The objective was to determine the level of evidence1 of each of the references; for example, a systematic review publication has a higher level of evidence than a practice guideline, which in turn is higher than a case report.
Medpedia is a medical online wiki launched in beta this past February to provide information about health, medicine and the body. It uses the Wikipedia model, but unlike Wikipedia, the content is written and edited by physicians and PhDs. Anyone can suggest a change, but the changes are reviewed by an editor before anything is made live on the site.
In March, Ansuman Chattopadhyay, head of the Health Sciences Library System’s Molecular Biology Information Service, traveled to Delhi, India, to lecture at the International Workshop on Psychiatric Genetics, Ethics and Related Methodological Issues. In addition to Chattopadhyay, other presenters included faculty from the University of Pittsburgh, University of Pennsylvania and University of Virginia, as well as the director of India’s Centre for DNA Fingerprinting and Diagnostics (CDFD).» Next Entries
