Team building with information system departments: a hospital librarian's experience in coexisting, collaborating, and cooperating.

Hospital librarians and information systems (IS) staff regard themselves as information professionals and have coexisted in the same institutions for many years. While hospital librarians have increased their computer literacy, IS staff have begun to recognize the value of knowledge-based information as an IS resource. Parallel growth and mutual interest have resulted in increased opportunities for information professionals to share skills and network for mutual advantage. Creating positive relationships between the hospital librarian and IS staff can be critical to the success of the hospital library. This paper provides a framework in which to explore the levels of relationship that exist within institutions between hospital librarians and IS staff. The "knowing/caring ladder" is presented as a model to illustrate levels of relationship and their consequences. The authors contend that recognition of the levels of professional relationship determines the success or failure of team building.

Cross-national comparisons of ageing mothers of adults with intellectual disabilities.

Ageing (55+ years) mothers of adults with intellectual disabilities in the Republic of Ireland, Northern Ireland and the United States were compared with respect to three general issues. Firstly, to what extent do the adults in these three countries differ in their level of reliance on their mothers? Secondly, do the mothers differ in the extent to which they have made plans for the future care of their son or daughter with intellectual disabilities? Thirdly, do the mothers differ in physical, social and psychological well-being? These cross-national comparisons were undertaken to examine the extent to which lifelong caregiving has either a common influence on mothers across national boundaries, or, alternatively, whether the cultural context exerts a unique influence on mothers in each country. Findings supported the latter explanation, even when background characteristics were statistically controlled.

The effects of fescue toxicosis on beef cattle productivity.

Consumption of tall fescue forage infested with the endophytic fungus Acremonium coenophialum can result in a condition termed "fescue toxicosis," which is characterized by decreased weight gains, milk production, conception, and serum prolactin and an inability to dissipate body heat by beef cattle. These decreases in productivity have been estimated to cost beef producers more than $600 million annually. The unthrifty appearance of cattle consuming endophyte-infected tall fescue (E+) is most evident during periods of environmental heat or cold stress, suggesting an interaction with environmental conditions. Without temperature stress, cows consumed similar amounts of E+ and endophyte-free tall fescue (E-). But, when temperatures exceeded 32 degrees C, cows that grazed E+ consumed less forage than cows that grazed E-. After removal of E+ from the diet of steers, compensatory growth was observed, indicating no long-term negative effects of E+. A decrease in serum prolactin but apparently little change in other hormones has been measured after consumption of E+. Under periods of heat stress, animals had reduced ability to dissipate body heat, and blood flow to peripheral (rib skin), core-body (duodenum colon), and brain (cerebellum) tissues was decreased. Due to the depressive effects of E+ on prolactin and heat dissipation, dopamine antagonist therapy has been used in an attempt to rectify these changes. Dopamine antagonists have increased serum prolactin but there is limited evidence to suggest an improvement in heat dissipation. Experiments to elucidate the effects of E+ on alpha-1 and -2 adrenergic receptors may also offer insights into developing strategies to overcome the negative effects of E+ consumption. Preliminary results suggest that injections of an alpha-1 adrenergic antagonist (prazosin) in rats fed E+ under 32 degrees C conditions increased DM intake and reduced rectal temperature.
