Indigenous journal publication is vital to the well-being of the African research enterprise in ways that the high-profile initiatives of Western publishers have, so far, failed to address. This paper describes the scope and development of African Journals Online, a free service which provides online access to the tables of contents and abstracts of scholarly journals published in Africa, backed by a document delivery service and managed by the International Network for the Availability of Scientific Publications.  相似文献

Web of deceit: A literature review of Munchausen syndrome by proxy   总被引:5,自引:0,他引:5  
Munchausen syndrome by proxy (MSBP) is a form of child abuse wherein the mother falsifies illness in her child through simulation and/or production of illness, and presents the child for medical care, disclaiming knowledge as to etiology of the problem. From the literature, 117 cases of MSBP were reviewed. The most common presentations of MSBP were bleeding, seizures, central nervous system depression, apnea, diarrhea, vomiting, fever, and rash. Short-term morbidity rate was 100%; long-term morbidity rate was 8%. Mortality rate was 9%. Failure to thrive was associated with MSBP in 14% of cases. All perpetrators of MSBP were the mothers. The origins of this type of aberrant maternal behavior remain abstruse, as do the long-term psychological effects on the child victims. Guidelines for medical, social service, and legal management are provided.  相似文献

In this study, the dual-task paradigm was used to determine peak attentional demand during the free-throw process. Thirty participants completed 40 free-throw trials. The free throw was the primary task, but participants also verbally responded to a tone administered at one of four probe positions (PP). Repeated measures analysis of variance showed no significant difference in free-throw performance across PPs, indicating participants were able to keep the free throw as the primary task. Repeated measures analysis of response time (RT) showed significant differences, with RT at PP1 (preshot routine) and PP2 (first upward motion of the ball) significantly higher than baseline RT. These results suggest that PP1 requires the greatest attentional demand, followed by PP2.  相似文献
