The authors construct locally optimal designs for the proportional odds model for ordinal data. While they investigate the standard D‐optimal design, they also investigate optimality criteria for the simultaneous estimation of multiple quantiles, namely DA ‐optimality and the omnibus criterion. The design of experiments for the simultaneous estimation of multiple quantiles is important in both toxic and effective dose studies in medicine. As with c‐optimality in the binary response problem, the authors find that there are distinct phase changes when exploring extreme quantiles that require additional design points. The authors also investigate relative efficiencies of the criteria.  相似文献

In the Philippines, measurement of social indicators covering Qualityof Life and other social concerns has been institutionalized by means ofa unique Social Weather Reporting system. The Social Weather Reports arebased on a series of national surveys operated on a self-sustaining,syndicate-cum-omnibus basis by a private research institute whichoperates as an “enterprising non-profit.” The surveys began on asemestral basis in 1986 and have been run quarterly since 1992. Amongtheir regular topics are self-rated poverty, QOL gaining/losing andoptimism/pessimism, victimization by common crimes, satisfactionwith the performance of government institutions and officials, publicopinion on contemporaneous critical issues, and electoral prospects.Since the topics all deal with public issues, subscribers to the SocialWeather Reports are mostly from the public sector, plus some corporateand diplomatic institutions. Access of non-subscribers to the surveyfindings is on a delayed basis; all surveys are archived for publicuse. The most important factors behind the success of the Social WeatherReports have been their consistent focus on indicators of democracy andgovernance and their record in predicting the outcomes of the 1992,1995, and 1998 national elections in the Philippines.  相似文献

Aphasia is an acquired language impairment that affects over 1 million individuals, the majority of whom are over age 65 (Groher, 1989). This disorder has typically been conceptualized within a cognitive neuroscience framework, but a behavioral interpretation of aphasia is also possible. Skinner''s (1957) analysis of verbal behavior proposes a framework of verbal operants that can be integrated with the work of Sidman (1971) and Haughton (1980) to describe the language difficulties individuals with aphasia experience. Using this synthesis of models, we propose a new taxonomy of aphasia based on the observed deficit relations. Assessment and treatment implications are also discussed.  相似文献

For most of us, our cognitive functioning could be improved in many ways. Many of us struggle with our thinking skills at times, especially during times of stress and information overload. Some of the research that supports the use of prescribed cognitive exercises to slow cognitive decline in older adults may ultimately prove to be beneficial for all of us. Mental health nurses should encourage regular daily mental workouts, along with aerobic physical exercises, for everyone, not just older adults. Personal fitness training should focus not only on physical fitness, but also on mental fitness.  相似文献

There is perhaps no more pressing issue in school policy today than the achievement gap across social lines. Achievement differences between well-to-do children and poor children and between disadvantaged racial and ethnic minorities and majority whites are large when children first begin school, and they increase over time. Despite years of study and an abundance of good intentions, these patterned achievement differences persist, but who is responsible, and how are schools implicated? The increasing gap seems to suggest that schools are unable to equalize educational opportunity or, worse still, that they actively handicap disadvantaged children. But a seasonal perspective on learning yields a rather different impression. Comparing achievement gains separately over the school year and the summer months reveals that much of the achievement gap originates over the summer period, when children are not in school. The authors review Beginning School Study research on differential summer learning across social lines (that is, by family socioeconomic level) and its implications for later schooling outcomes, including high school curriculum placements, high school dropout, and college attendance. These studies document the extent to which these large summer learning differences impede the later educational progress of children of low socioeconomic status. Practical implications are discussed, including the need for early and sustained interventions to prevent the achievement gap from opening wide in the first place and for high-quality summer programming focused on preventing differential summer learning loss.  相似文献

Contemporary labor markets are characterized by both aging of the workforce and the increase in participation of women. At the intersection of these two policy agendas are older women. Governments and employers recognize the importance of attracting and retaining older workers to address skills shortages, but the aging workforce discourse remains largely gender neutral. This research considers the intersection of age and gender in the context of public services, which are large employers of both women and older workers. It focuses on the agencies in an Australian state public service. The research finds that, despite decades of equal opportunity programs, there is still evidence of subtle inequalities and cumulative disadvantage. While the case study agencies employ a large proportion of older women, these women were generally recruited at younger ages and aged within the workforce. Their advancement and development opportunities were also inferior to those of older men. Despite these lesser opportunities, older women are generally very satisfied with their employment, and the employer should explore these residual inequalities if genuinely seeking to attract and retain all older workers.  相似文献

China has the world's largest oldest‐old population, but information on trends in late‐life disability is lacking. We use data from the Chinese Longitudinal Healthy Longevity Survey for 1998 to 2008 to determine whether prevalence of limitations with physical functions and daily activities has changed recently among the Chinese population aged 80 to 105 and, if so, to investigate the factors associated with the change. We find that prevalence of need for assistance with activities of daily living and inability to independently conduct instrumental activities of daily living declined substantially. Males did not experience improvement in ability to carry out underlying physical functions over the same period, but females did. Variables associated with trends in one or more of these outcomes were adequacy of medical care as a child, childhood hunger, father's occupation in agriculture, main occupation before age 60 in agriculture, adequacy of current medical care, and body weight.  相似文献

Although it is only a minority of displaced and persecuted people globally who seek refuge in ‘Western’ countries, they meet an increasingly hostile reception. This paper focuses on the situation facing children seeking asylum with or without their families in Britain and Australia, and the implications for children's rights and for social work. The policy background and its racist foundations in both countries are outlined. Despite geopolitical differences, there are unnerving parallels. Legislative changes and policy complexity signal increasingly punitive attitudes towards asylum seekers. The situation of children and families in the community is discussed in terms of the exclusion of asylum seekers from basic rights, and specific issues for separated children. Even more damaging is the incarceration of children and families in detention centres, and the emerging research is explored. In both countries there is widespread flouting of children's rights, and children also feature as pawns in ideological contests. However, they also act autonomously and illustrate an inclusive model of citizenship. The role of social workers in the statutory and voluntary sectors is considered, and the paper concludes with a discussion of the challenges for social work of avoiding collusion with repressive policies and actively promoting human rights.  相似文献

Family involvement in managing the financial assets of olderpeople is an area of policy and practice importance. This importancerelates to the complexity of older people’s assets, systemsof paying for care and concerns around substitute decision-makingand financial abuse. Although a common task of informal care,little is known about older people’s experiences and wishesin relation to asset management. This paper reports on a qualitativestudy of the experiences and perspectives of thirty-four olderpeople receiving such assistance. It identifies three scenariosthat promote or inhibit independence in this context and drawsout the challenges for this emerging area of practice with olderadults and their families.  相似文献
