Results that bear upon the psychometric properties of the Quality of Life Instrument Package are presented. The reliability and validity of quality of life data from a probability sample of 500 persons with developmental disabilities in Ontario were assessed. The data indicate that most of the instruments found in the package met acceptable psychometric standards. In some cases, specific domain scores need to be interpreted with caution. The Full Version of the instrument seems appropriate for ongoing practical program planning with clients. The Short Version seems especially appropriate for evaluation and monitoring purposes. 相似文献

We apply the comparative techniques originated by Wolpin, K.I. (1977, Education and screening, American Economic Review, 67, 949–958) and Psacharopoulos (1979, On the weak versus the strong version of the screening hypothesis, Economics Letters, 4, 181–185) to discriminate between the ‘weak' and ‘strong' screening hypotheses. Controlling for sample selection, we find evidence for weak but not strong screening in the Italian labour market. [JEL J3, J24, J41] 相似文献

Change in social customs and institutions is usually a slow process. This seems particularly true in attitudes about child abuse. Two key elements for change are being utilized for child protection in a rural area of Alaska with a predominantly Caucasian population. First, application of an old church custom of "constructive gossip" by volunteers is changing this rural community attitude about children. Second, use of an innovative federal government health care delivery program has established this community's first obstetric and pediatric service. With the oil boom in Alaska, widespread family disruption with frequent child abuse and neglect has become commonplace. Despite the oil tax wealth, State of Alaska Child Protection Services are strained to keep up with family and community violence. Deliberate cooperation with local community, church and service organization leaders is helping keep up with child protection needs. The obstetric and pediatric specialists of the National Health Service Corps non-profit practice were co-leaders, along with community leaders, in starting a lay volunteer service called "Friends of Families." Working cooperatively with the state child protection office, 24 families have received assistance from parent aides of Friends of Families. The influence of these two key elements of change on rural community attitudes and institutions are described. 相似文献

This article proposes the incorporation of learning science into the programming and operation of public libraries. Learning science, a multidisciplinary field spanning cognitive science, psychology, neuroscience, economics, anthropology, and linguistics, has identified proven methods for enhancing learning at any age. The article highlights some of the tools and insights that are most relevant to libraries in their role as centers for informal learning. 相似文献

Heavy training is associated with increased respiratory infection risk and antimicrobial proteins are important in defence against oral and respiratory tract infections. We examined the effect of 14 weeks of vitamin D3 supplementation (5000 IU/day) on the resting plasma cathelicidin concentration and the salivary secretion rates of secretory immunoglobulin A (SIgA), cathelicidin, lactoferrin and lysozyme in athletes during a winter training period. Blood and saliva were obtained at the start of the study from 39 healthy men who were randomly allocated to vitamin D3 supplement or placebo. Blood samples were also collected at the end of the study; saliva samples were collected after 7 and 14 weeks. Plasma total 25(OH)D concentration increased by 130% in the vitamin D3 group and decreased by 43% in the placebo group (both P = 0.001). The percentage change of plasma cathelicidin concentration in the vitamin D3 group was higher than in the placebo group (P = 0.025). Only in the vitamin D3 group, the saliva SIgA and cathelicidin secretion rates increased over time (both P = 0.03). A daily 5000 IU vitamin D3 supplement has a beneficial effect in up-regulating the expression of SIgA and cathelicidin in athletes during a winter training period, which could improve resistance to respiratory infections. 相似文献

Football is central to Brazilian society, its way of imagining itself and its position in the world. Existing accounts of the origins of football in Brazil in the late nineteenth- and early twentieth-centuries tend towards mono-causal explanations, highlighting the role of British pioneers and Brazilian enthusiasm for the game. This article argues for a multi-causal explanation, using a mixed methodology of archival research in Brazil and the UK, combined with spatial analysis through the development of GIS maps. Building upon the existing interpretations, it shows how important the historical contexts of dynamics of urban expansion and transport infrastructure development – both with considerable British influence – were to the establishment of football as Brazil's national sport. 相似文献

Effectively conveying risks and hazards in medical disclosure and informed consent documentation is a crucial type of communication. However, existing protocols typically do not meet the needs of patients or practitioners. In the present study, we advance a reconceptualization of obtaining written informed consent by analyzing it as a process of uncertainty management rather than a matter of document readability and recall. Results of this randomized trial indicated that patients who reviewed a simplified consent document reported greater comprehension of medico-legal terminology and lower uncertainty about the document, although they did not evince greater self-efficacy. Health literacy was a significant moderator of the relationship between consent form version and comprehension. 相似文献
