订购粮价政策年内出台

近日,农业部部长刘江向记者证实,国家将在年内适当提高粮食订购价格。这一政策的出台是为了保证农产品供求均衡增长和提高农民的收入。政策出台前专家多方论证 1995年年底,农业专家们就针对这个问题展开研究和讨论,并进行了有益的建议和论证。在《1995—1996:中国农村经济形势回顾与展望》一文中,作者这样写到:“逐步提高国家订购价,使其基本上接近市场价格,将是不可     

Introducing computer literacy skills for physicians

Computers are integral to medical practice, education, and research. While medical students learn computer skills during their training, many practicing physicians do not have the same computer experience. To familiarize this group with the exciting developments in medical informatics, the Himmelfarb Health Sciences Library and Department of Computer Medicine at the George Washington University Medical Center organized a workshop "Introducing Your Office Computer!" for attending physicians. The workshop featured a short lecture/video presentation on computer applications in medicine followed by a "computer fair" of five computer applications. Eleven physicians attended the workshop. Feedback was very positive; many called later to request more detailed instructions on using the programs demonstrated. It was a valuable experience for the staff, and new bridges were built between departments and clients.

Advances in the phylogenesis of Agaricales and its higher ranks and strategies for establishing phylogenetic hypotheses

We present an overview of previous research results on the molecular phylogenetic analyses in Agaricales and its higher ranks (Agaricomycetes/Agaricomycotina/Basidiomycota) along with the most recent treatments of taxonomic systems in these taxa. Establishing phylogenetic hypotheses using DNA sequences, from which an understanding of the natural evolutionary relationships amongst clades may be derived, requires a robust dataset. It has been recognized that single-gene phylogenies may not truly represent organismal phylogenies, but the concordant phylogenetic genealogies from multiple-gene datasets can resolve this problem. The genes commonly used in mushroom phylogenetic research are summarized.     

Inspiring vanguards: the Woods Hole experience

Twice a year, the National Library of Medicine and Marine Biological Laboratory co-sponsor a fellowship in Biomedical Informatics for librarians, clinicians, and other health professionals in Woods Hole, MA. The fellowship is designed to inspire participants to become "agents of change" at their institution and to broaden their scope of knowledge for biomedical informatics. This paper discusses the field of biomedical informatics and explores the results of an informal survey from the librarians who participated in the fall session of 2005.
