The National Library of Medicine has had an enormous impact on health information services all over the world. Although NLM is primarily a national institution, it has become an important international resource by responding to requests from the international community. NLM has been influential in three major ways. First, NLM has provided a model for other national and regional health information services. Second, it has been a catalyst, in that MEDLARS and other services it provides formed the nucleus of many regional networks. NLM helped such networks get started by giving advice on how to set up services and build collections and by "training the trainers" on the MEDLARS system. Third, NLM has supported national and regional operations by providing the additional training and materials needed for day-to-day service.  相似文献

The history of nursing education in America is briefly told, with the growth of education in institutions of higher learning emphasized. Two trends in nursing education are paralleled by similar developments in nursing literature. The growth of scholarship in nursing is also noted. It is pointed out that nursing is a discipline in its own right, and that training for leadership is required. Continuing education programs are mentioned, together with the increase in nursing literature. Integrated libraries for the health sciences are recommended.  相似文献

ABSTRACT

Social media is a powerful tool for building an online presence, but it asks a lot. While it affords plentiful opportunities for professional development and networking, building a professional brand in an online space is not without its drawbacks and risks. By working from a set of actionable principles and benchmarks, users can minimize frustrations and setbacks to build a useful professional presence, all while imbuing the web with the tenets of good information stewardship.  相似文献

Increased genetic testing in personalized medicine presents unique challenges for couples, including managing disease risk and potential discrimination as a couple. This study investigated couples’ conflicts and support gaps as they coped with perceived genetic discrimination. We also explored the degree to which communal coping was beneficial in reducing support gaps and ultimately stress. Dyadic analysis of married adults (N?=?266, 133 couples), in which one person had the genetic risk for serious illness, showed that perceived discrimination predicted more frequent conflicts about alpha-1 antitrypsin deficiency-related treatment, privacy boundaries, and finances, which, in turn, predicted wider gaps in emotion and esteem support, and greater stress for both spouses. Communal coping predicted lower support gaps for both partners and marginally lower stress.  相似文献
