Selected AbstractsThe influence of HIV/AIDS on the practice of primary care nurses in Jordan: Rhetoric and realityINTERNATIONAL JOURNAL OF NURSING PRACTICE, Issue 5 2005Hani Nawafleh PhD(Cand) The role of nurses in raising community awareness about HIV/AIDS is well-reported. However, little is known about the practice of Jordanian nurses and the role they play in the prevention and control of HIV/AIDS. This interpretive ethnographic study sought to illuminate the role of primary care nurses and examine the influence of HIV/AIDS on their practice. The study was undertaken in Jordan in three rural and three urban primary health-care centres. Data collection included participant observation, key informant interviews and document analysis. These data informed the development of descriptive ethnographic accounts that allowed for the subsequent identification of common and divergent themes reflective of factors recognized as influencing the practice of the nurse participants. The findings indicate that the rhetoric offered by all levels of administration and endorsed in policy is not reflective of the reality of practice. Poor resources and educational preparation, a limited nursing skill mix and access to professional development, lack of nursing leadership and role models, cultural beliefs and geographic isolation are factors that reduced the capacity of the primary care nurses to raise awareness and, therefore, influence the prevention and control of HIV/AIDS. [source] The role of food and colony size in sexual offspring production in a social insect: an experimentECOLOGICAL ENTOMOLOGY, Issue 1 2007JOUNI SORVARI Abstract 1.,Large colonies of ants are known to have a higher propensity for sexual offspring production, probably owing to their high capacity to exploit food resources. 2.,The effects of food supplementation on the propensity for sexual offspring production, and whether it is linked with colony size, were investigated in an environment with poor resources (clear-cut areas). 3.,Large colony size was associated with a higher propensity for sexual offspring production in food-supplemented colonies, whereas in non-supplemented control colonies an association with colony size was not found. 4.,The results demonstrate that large colonies seem to have a higher capacity to exploit supplemented food. In addition, the production of sexual offspring was apparently limited by food availability in clear-cuts, especially for large colonies. [source] Trading off the ability to exploit rich versus poor food qualityECOLOGY LETTERS, Issue 5 2002Alan J. Tessier Abstract Lakes differ in the quality of food for planktonic grazers, but whether grazers adapt to this resource heterogeneity is poorly studied. We test for evidence of specialization to resource environment within a guild of suspension feeding daphniids inhabiting lakes that differ in food web structure. Using bioassays, we demonstrate that food quality for grazers increases from deep to shallow to temporary lakes, which also represents a gradient of increasing predation risk. We compare growth rates and reproductive performance of daphniid taxa specific to each of the three lake types and find they differ greatly in minimum resource requirements, and in sensitivity to the resource gradient. These differences express a trade-off in ability to exploit rich vs. poor resources. Taxa from deep lakes, poor in resources, have low minimal needs, but they do relatively poorly in rich resource environments. We conclude that grazer distribution is consistent with an adaptive match of exploitation ability to resource environments. [source] Patterns of systemic stress during the agricultural transition in prehistoric JapanAMERICAN JOURNAL OF PHYSICAL ANTHROPOLOGY, Issue 1 2010Daniel H. Temple Abstract This study documents and interprets systemic stress during the agricultural transition in prehistoric Japan using linear enamel hypoplasia (LEH) defects and cribra orbitalia (CO) lesions. Middle to Final Jomon cultures (5000,2300 BP) from Honshu Island represent the foraging samples, while Yayoi cultures (2500,1700 BP) represent the early agricultural samples. Jomon foragers from eastern Japan had broad-based, intensive economies. Jomon foragers from western Japan had a greater focus on seasonally available, nutritionally poor resources, while Yayoi people were descendents of migrants from the East Asian continent and introduced wet rice economies to Japan. This study tests the hypotheses that wet rice economies will be associated with a lower prevalence of teeth/individuals affected by LEH defects in western Japan, while few differences in the prevalence of teeth/individuals with LEH defects will be observed between eastern Jomon people and Yayoi farmers. It is further predicted that similar CO prevalence will be observed between Jomon and Yayoi people given environmental similarities. Significantly greater frequencies of teeth affected by LEH defects are observed among western Jomon compared to Yayoi people. The prevalence of teeth with LEH defects is slightly elevated among eastern Jomon foragers compared to Yayoi agriculturalists. Significant differences in CO prevalence are not observed. Systemic stress prevalence in western Japan likely declined following wet-rice agriculture because this crop provided a predictable, renewable resource base. Systemic stress prevalence was similar between eastern Jomon and Yayoi people because both groups practiced intensive subsistence strategies. Similar CO prevalence reflects infectious diseases associated with living conditions. Am J Phys Anthropol, 2010. © 2009 Wiley-Liss, Inc. [source] | ||||||||||
