PROBLEM: After the Soviet Union dissolved in 1989, it became apparent that there was little recognition of the problems of child abuse and neglect, professionally, legally, or societally. There were no effective systems or laws in place to deal with these problems. METHOD: Beginning in 1995 the Children's Mental Health Alliance, in conjunction with the Open Society Institute began conducting trainings in Eastern Europe [Journal of the American Academy of Child Adolescent Psychiatry 39 (2000) 660]. Originally 18 countries from the Baltics to the Balkans participated. A program was elaborated which would proceed in several stages: (1) training mental health professionals to deal with child abuse and neglect (CAN); (2) teaching multidisciplinary team work and fostering the development of multidisciplinary NGOs focused on CAN; (3) promoting the self-sufficiency of these NGO's which would then facilitate social and legal reform and increase public awareness of the problem. Specific methods included multi-national trainings, assignment of mentors to the developing teams who maintained weekly contact with the teams and made yearly site visits to their countries, and overseeing project grants from OSI. RESULTS: NGO's had been established and registered in 11 countries, many establishing a network of programs within their countries. By 2000, over 3800 mental health professional had been trained, either directly by the program or by the trainees of the program. By the end of 2000, over 17,000 other professionals (lawyers, police, judges, educators, other physicians, etc.) had been trained by the network. CONCLUSION: While more work needs to be in this region, the teams in 11 countries have made solid starts. 相似文献

主要芯片制造商（如nVIDIA）最近的一些举动较之前更确切无疑地表明,微处理器及大型高性能计算（HPC）系统未来的设计从本质上说都将是混合／异构的。这些异构系统将依赖于这两大类型的组件以不同的比例集成。 相似文献

The value and impact of information provided through library services for patient care: a systematic review 总被引：1，自引：1，他引：0

OBJECTIVE: An updated systematic review was carried out of research studies looking at the value and impact of library services on health outcomes for patients and time saved by health professionals. METHODS: A comprehensive systematic search was undertaken of the published literature to September 2003 in ERIC, LISA, MEDLINE, PREMEDLINE, EMBASE, the Cochrane Controlled Trials Register and Google. Some handsearching was carried out, reference lists were scanned and experts in the field were contacted. Twenty-eight research studies of professionally led libraries for health-care staff, including clinical librarian projects, met the inclusion criterion of at least one health or 'time saved' outcome. Papers were critically appraised using internationally accepted criteria. Data were extracted and results were summarised using a narrative format as the studies were heterogeneous and precluded a statistical analysis. RESULTS: There is evidence of impact from both traditional and clinical librarian services. The higher quality studies of traditional services measured impacts of 37-97% on general patient care, 10-31% on diagnosis, 20-51% on choice of tests, 27-45% on choice of therapy and 10-19% on reduced length of stay. Four studies of clinical librarian projects suggested that professionals saved time as a result of clinical librarian input, and two of these studies showed evidence of cost-effectiveness. However, the clinical librarian studies were generally smaller, with poorer quality standards. CONCLUSIONS: Research studies suggest that professionally led library services have an impact on health outcomes for patients and may lead to time savings for health-care professionals. The available studies vary greatly in quality but the better quality studies also suggest positive impacts. Good practice can be gathered from these studies to guide the development of a pragmatic survey for library services that includes the direct effects for patients among the outcome measures. 相似文献

Infant vocalizations are early-emerging communicative markers shown to be atypical in autism spectrum disorder (ASD), but few longitudinal, prospective studies exist. In this study, 23,850 infant vocalizations from infants at low (LR)- and high (HR)-risk for ASD (HR-ASD = 23, female = 3; HR-Neg = 35, female = 13; LR = 32, female = 10; 80% White; collected from 2007 to 2017 near Philadelphia) were analyzed at 6, 12, and 24 months. At 12 months, HR-ASD infants produced fewer vocalizations than HR-Neg infants. From 6 to 24 months, HR-Neg infants demonstrated steeper vocalization growth compared to HR-ASD and LR infants. Finally, among HR infants, vocalizing at 12 months was associated with language, social phenotype, and diagnosis at age 2. Infant vocalizing is an objective behavioral marker that could facilitate earlier detection of ASD. 相似文献
