The performance of Anderson's classification statistic based on a post-stratified random sample is examined. It is assumed that the training sample is a random sample from a stratified population consisting of two strata with unknown stratum weights. The sample is first segregated into the two strata by post-stratification. The unknown parameters for each of the two populations are then estimated and used in the construction of the plug-in discriminant. Under this procedure, it is shown that additional estimation of the stratum weight will not seriously affect the performance of Anderson's classification statistic. Furthermore, our discriminant enjoys a much higher efficiency than the procedure based on an unclassified sample from a mixture of normals investigated by Ganesalingam and McLachlan (1978).  相似文献

Early childhood education and care affects millions of young people, their parents, and ultimately society at large. Social workers are employed directly in early childhood education and care programs and also witness the results of inadequate early interventions in various practice settings. Yet social workers do little of the research related to this topic. Numerous issues relate to both social work and to thoughtful discussions of early childhood education and care, including the unequal use of high quality early education programs, which is ultimately a social justice issue. This article elucidates how social workers can and why they should contribute to practice, policy, and research related to early childhood education and care.  相似文献

Influenced by the consumerist sentiment in New Public Management,the last decades have witnessed a revival of the call for accountabilityto service users in the public service sector. As an act ofaccountability, social care and health care professionals areincreasingly obliged to involve their service users in the serviceplanning and monitoring process. Despite the popularity of thisaccountability and user involvement rhetoric, critics have,however, been skeptical of the prevailing user involvement initiativesas an effective measure of accountability to service users (Barnes and Wistow, 1994a,1994b; Bowl, 1996; Peck et al., 2002; Rea, 2004). Based on astudy of user involvement in the welfare sector of Hong Kong,this paper argues that the discourse of accountability to theservice users can be a source of unrest for welfare professionals,in the manifestation of accountability as a power relationship.Their ensuing response is to accommodate the ensuing challengearising from the demand for accountability to service usersby manoeuvring the accountability discourse. It is the contentionof this paper that the institutional inclusion of welfare serviceusers into a discursive space is a necessary but not sufficientcondition for the realization of a mandate of accountabilityto welfare service users.  相似文献

Components of nursing home (NH) culture change include resident-centeredness, empowerment, and home likeness, but practices reflective of these components may be found in both traditional and “culture change” NHs. We use mixed methods to examine the presence of culture change practices in the context of an NH’s payer sources. Qualitative data show how higher pay from Medicare versus Medicaid influences implementation of select culture change practices, and quantitative data show NHs with higher proportions of Medicare residents have significantly higher (measured) environmental culture change implementation. Findings indicate that heightened coordination of Medicare and Medicaid could influence NH implementation of reform practices.  相似文献

Abstract

The Retirement System for Veteran Cadres (Lixiu) is one part of China’s dual-track retirement system. According to some official policies, retired veteran cadres should enjoy a number of privileges in terms of pension, health care, use of government vehicle, housing and peculiar political rights. Based on participant observation and semi-structured interview, the study looks into the life of the population in a residential community of Jinan Municipal Party Committee, Shandong Province. By incorporating Maslow’s hierarchy of needs theory, the study finds that in China, services for retired cadres still fall short of the expectations of policy. Establishment of ‘big communities’ with the idea of ageing-in-place is suggested.  相似文献

Drawing on the concept of “tactile space,” we evaluate the experiential learning environment of a university extension field day event focused on a sustainable agriculture innovation: biodegradable plastic mulch. Introduced by sociologist Michael Carolan, “tactile spaces” are sensuously rich learning environments where participants interact with each other and the environment in an “embodied” and “embedded” manner leading to long‐lasting attitudinal and behavioral change. In our study, farmers, extension professionals, crop consultants, and mulch manufacturers participated in a field day event designed to provide both embodied and embedded experiences in an effort to stimulate interest in biodegradable plastic mulch, an economically and environmentally sustainable alternative to polyethylene mulch. Field day participants engaged in hands‐on demonstrations preceded and followed by focus group sessions. Enhancing the learning environment in these ways improved the success of the field day event by encouraging practice‐based forms of learning, which supplemented and reinforced the claims made about biodegradable plastic mulch. However, the tactile space could have been enriched by providing more opportunities for participants to become embedded within the environment, and by adding elements to overcome the temporal limitations of the field day event. This research contributes to the broader literature on participatory research and extension.  相似文献

The certification test for English teachers in a certain state asked candidates to identify the name of the frog in Mark Twain's "The Celebrated Jumping Frog of Calaveras County." If students answered this question correctly and said, Dan'l Webster, does this mean that these students would be prepared for the teaching field? Conversely, if students answered this question incorrectly, does this mean they were ill - prepared for becoming teachers? Can such an irrelevant question really point to the knowledge and abilities of future teachers? Hardly, use of unimportant questioning such as this illustrates the main problem with using a multiple choice format when assessing students. Trivial items such as names of animals and other insignificant information are often given priority over their significance in the story simply because students are not able to demonstrate what they really know in narrative form (Smagorinsky, 2002).  相似文献

The current literature on aging and ageism is summarized in support of a theoretical perspective that includes both the biological and the psychosocial components of these processes. Conceptual and methodological problems are identified in models that rely on a deficit approach to aging. We suggest that the biased responses of others foster older adults' stress-related emotional and hormonal responses—responses that may effectively reduce their social and cognitive competence. This negative feedback process ultimately acts in a stereotype-maintaining fashion. Implications are drawn for possible changes in social policy and institutional practices that may reduce or prevent the harmful effects of ageism. Examples are given of existing policies and practices that limit the lives of older adults (in the guise of protection), along with newly instituted policies and practices (including those at an international level) that place the welfare of older adults in the context of life course issues shared by all.  相似文献

ABSTRACT

This article explores the technical limitations of audio recordings and how those limitations impact the reliability of sound evidence in police use of force cases. In audiovisual recordings, audio is often assumed neutral, redundant or to have the same limitations as its visual counterpart. Bringing together film theorist Michel Chion’s concept of audio-vision and the technical specifications of mobile audio recording, this article highlights how design priorities and compression processes can influence the way sound evidence is perceived. By failing to acknowledge audio recordings as distinct from their visual counterparts, they are rendered invisible and are therefore under scrutinized throughout legal processes. This neglect becomes notably problematic in cases of police use of force where audio/visual recordings often work to bolster the already privileged officer testimony.  相似文献

Wang KY‐T, Wong C‐k, Tang K‐L. Citizens' attitudes towards economic insecurity and government after the 2007 financial tsunami: A Hong Kong and Taiwan comparison The purpose of this study was to investigate people's attitudes to economic insecurity and government in Hong Kong and Taiwan after the financial tsunami of 2007. Random sampling telephone surveys were conducted in July 2009. These are the main conclusions: First, the most vulnerable groups hurt by the financial crisis were low‐income families and people who had lost their job or were afraid of losing it. This implies that the old policy issue of social stratification and the emerging policy issue of employment insecurity coexisted during the financial crisis. Second, personal experiences of economic insecurity had an influence on people's perceptions of the severity of the economic crisis at the societal level. Third, citizens had ambivalent feelings about public interventions during the crisis. Fourth, there were both convergence and divergence between Hong Kong and Taiwan with regard to attitudes to particular issues. The policy implications of these findings are discussed in the final section of this article.  相似文献
