Although the HIV/AIDS epidemic began more than twenty years ago, there still is no cure for the disease and no vaccine to prevent infection. As with the general population, individuals with HIV/AIDS have sought care using a variety of traditional and nontraditional approaches. The popularity of complementary and alternative interventions among the HIV/AIDS community continues. To understand better the distribution of the HIV/AIDS body of knowledge concerning complementary and alternative medicine (CAM), this study sought to (1) examine the literature specific to the use of complementary and alternative medicine where HIV/AIDS is concerned to determine publication patterns; (2) determine the degree of overlap among bibliographic citation databases that index the literature concerning the use of CAM practices in treating HIV/AIDS; and (3) facilitate access to this body of literature.  相似文献

Although a portion of the HIV/AIDS population has long been active in seeking out information in support of self-care, little work has been done to examine closely the information needs and information-seeking behaviors of this community relative to the provision of medical reference. This exploratory study provides insight into the types of information HIV positive individuals seek and the resources they consult in gathering information to bolster health and well-being. Having a better understanding of the information needs and information-seeking behaviors of individuals with HIV/AIDS will facilitate information intervention for this community.  相似文献

Abstract

Bicycle helmets exhibit complex structures so as to combine impact protection with ventilation. A quantitative experimental measure of the state of the art and variations therein is a first step towards establishing principles of bicycle helmet ventilation. A thermal headform mounted in a climate-regulated wind tunnel was used to study the ventilation efficiency of 24 bicycle helmets at two wind speeds. Flow visualization in a water tunnel with a second headform demonstrated the flow patterns involved. The influence of design details such as channel length and vent placement was studied, as well as the impact of hair. Differences in heat transfer among the helmets of up to 30% (scalp) and 10% (face) were observed, with the nude headform showing the highest values. On occasion, a negative role of some vents for forced convection was demonstrated. A weak correlation was found between the projected vent cross-section and heat transfer variations when changing the head tilt angle. A simple analytical model is introduced that facilitates the understanding of forced convection phenomena. A weak correlation between exposed scalp area and heat transfer was deduced. Adding a wig reduces the heat transfer by approximately a factor of 8 in the scalp region and up to one-third for the rest of the head for a selection of the best ventilated helmets. The results suggest that there is significant optimization potential within the basic helmet structure represented in modern bicycle helmets.  相似文献

Objective

This study investigated responsibilities, skill sets, degrees, and certifications required of health care navigators in order to identify areas of potential overlap with health sciences librarianship.

Method

The authors conducted a content analysis of health care navigator position announcements and developed and assigned forty-eight category terms to represent the sample''s responsibilities and skill sets.

Results

Coordination of patient care and a bachelor''s degree were the most common responsibility and degree requirements, respectively. Results also suggest that managing and providing health information resources is an area of overlap between health care navigators and health sciences librarians, and that librarians are well suited to serve on navigation teams.

Conclusion

Such overlap may provide an avenue for collaboration between navigators and health sciences librarians.  相似文献
