Problem structuring heuristics and creative thinking techniques have been advanced as useful approaches for solving ill-structured problems. Unfortunately, little controlled experimentation has been done to test the effectiveness of these techniques. This paper describes an experiment in which the effects of training in the use of a problem-structuring heuristic and creative thinking on the quality and quantity of problem statements are investigated. The experiment illustrates that such training does have a positive impact on problem formulation quality and quantity. 相似文献

This paper explores issues of power and negotiation for two decisions affecting young women’s sexual lives: die decision to
have sexual intercourse and the decision to contracept. Using data from two recent Australian surveys the paper explores the
complexity of these decisions and the way in which gender relations between young people can influence dieir reproductive
outcomes; young women experience a high rate of sexual coercion and violence and current data collections do not allow analysis
of their cause. 相似文献

The present paper analyzes the incidence and progressivity of Vietnamese state income transfers using survey data from the Vietnamese Household Living Standards Survey 2004. Data quality and sample selection issues are highlighted, especially in the coverage of rural-urban migrants. Simple income-based profiles of incidence are matched to several influences that confound and complicate the measurement of progressivity. The issue of the informal economy is highlighted through analysis of both the extent of private inter-household transfers and remittances and their relationship with state transfers, and in the informal charges that accompany uptake of state services and other petty corruption. Second, the issue of user-charges for health and education services is considered, as a considerable portion of state transfers are related to the take up of schooling and health care. Third, the issue of behavioral effects is also considered, concentrating on private inter-household transfers. The paper concludes by drawing together the evidence and the obstacles to measurement and progressivity to argue a range of data collection, methodological and policy recommendations. 相似文献

This article shows theoretically and empirically that an aggregate Euler equation relates the growth rate of per capita consumption to the real interest rate, the ratio of private wealth plus asset income to consumption, and the ratio of social security wealth to consumption. Using the estimated Euler equation, the paper then calculates the steady-state effects of social security reform. Reforms that reduce the ratio of social security wealth to consumption are found to shift the balanced growth paths for the capital stock, output, and consumption upward appreciably. 相似文献

The Points to Consider Document on Missing Data was adopted by the Committee of Health and Medicinal Products (CHMP) in December 2001. In September 2007 the CHMP issued a recommendation to review the document, with particular emphasis on summarizing and critically appraising the pattern of drop‐outs, explaining the role and limitations of the ‘last observation carried forward’ method and describing the CHMP's cautionary stance on the use of mixed models. In preparation for the release of the updated guidance document, statisticians in the Pharmaceutical Industry held a one‐day expert group meeting in September 2008. Topics that were debated included minimizing the extent of missing data and understanding the missing data mechanism, defining the principles for handling missing data and understanding the assumptions underlying different analysis methods. A clear message from the meeting was that at present, biostatisticians tend only to react to missing data. Limited pro‐active planning is undertaken when designing clinical trials. Missing data mechanisms for a trial need to be considered during the planning phase and the impact on the objectives assessed. Another area for improvement is in the understanding of the pattern of missing data observed during a trial and thus the missing data mechanism via the plotting of data; for example, use of Kaplan–Meier curves looking at time to withdrawal.

Johansson S, Leonard R, Noonan K. Caring and the generation of social capital: two models for a positive relationship When caring is linked to social capital, it is generally assumed that the nature of the relationship is that social capital is a resource that can be used for care work. When there is inadequate funding of aged care services by the state, then social capital may be seen as a substitute for economic and human capital. Caring, therefore, is seen as a drain on capital. However, this does not have to be the case. Aged care services, if thoughtfully designed, can not only consume social capital, but also generate it. Two models of elder care, one Swedish and one Australian, have been identified which specifically address the generation of social capital. In each case, the services and facilities have been developed by third‐sector organisations with a strong community development focus, often in the face of resistance from state‐run or medically oriented services. 相似文献

Policy and practices relating to the active engagement of older people in the community: a comparison of Sweden and Australia 总被引:1,自引:1,他引:0
This article compares policy and practices for engaging older people in community life in Sweden and Australia. Barriers and support for active engagement through paid work, social activism, volunteering and aged services are compared. Both countries face issues of ageing populations, services for rural areas and people with small needs. Issues for Sweden were the absence of age discrimination legislation, availability of funds and lack of recognition of the growing levels of volunteering. Issues for Australia concerned the new managerialist approach to services, with associated complexities of access and limited social activism. 相似文献
