This paper studies long-term private health insurance (PHI) in Germany. It describes the main actuarial principles of premium calculation and relates these to existing theory. In the German PHI policyholders do not commit to renewing their insurance contracts, but insurers commit to offering renewal at a premium rate that does not reflect revealed future information about the insured risk. We show that empirical results are consistent with theoretical predictions from one-sided commitment models: front-loading in premiums generates a lock-in of consumers, and more front-loading is generally associated with lower rates of lapse. Due to a lack of consumer commitment, dynamic information revelation about risk type implies that high-risk policyholders are more likely to retain their PHI contracts than are low-risk types.  相似文献

The organized camp experience has been an important part of the lives of children, youth, and adults for over 150 years. The camp experience is a way for young people to explore and search for an authenticity often missing in other parts of their lives that contributes to their healthy transition into adulthood. Over the past decade, tremendous growth in the volume and rigor of camp-related research has occurred, facilitated by a targeted research agenda conducted by the American Camp Association. This agenda was founded on three national research projects conducted between 2003 and 2007: a study to identify the developmental outcomes of the camp experience, a benchmarking study of the youth development supports and opportunities provided through camp experiences, and a program improvement project directed toward enhancing supports and opportunities provided by camps. The findings from these research projects suggest that camp experiences promote developmental outcomes in both campers and staff and that camps provide the supports and opportunities needed for positive youth development. This article explores the developmental outcomes of the camp experience and the characteristics of the supports and opportunities afforded by camp experiences, including settings, structures, and programs and activities, as a way to provide a clearer understanding of camp as a positive youth development setting. Innovations and opportunities in research related to the provision of quality camp experiences are also considered.  相似文献

Recent debates of basic income (BI) proposals shine a useful spotlight on the challenges that traditional forms of income support are increasingly facing, and highlight gaps in social provisions that largely depend on income or employment status. A universal “no questions asked” public transfer would be simple and have the advantage that no-one would be left without support. But an unconditional payment to everyone at meaningful but fiscally realistic levels would likely require tax rises as well as reductions in existing benefits. We develop a comprehensive BI scenario that facilitates an assessment of the resulting fiscal and distributional effects in a comparative context, undertake a microsimulation study to quantify them, and propose a simple decomposition to identify the mechanisms that drive effects in different country contexts. Results illustrate the challenges, but also the strengths, of existing social protection systems. A BI would fix benefit coverage gaps that exist in many countries, but would require very substantial tax rises if it were to be set at a meaningful level. As support would not be targeted on those most in need, it would not be a cost-effective way of directly reducing income poverty.  相似文献

Surprisingly little has been written about the polarization between the white, aged, institutionalized client and the nonwhite paraprofessional despite the pervasiveness of this phenomena and its adverse effects. This paper explores the discrepancy between cultural values and practice. The ethnocultural factors that influence conflict and provide the background of behavior which is determined by programming that the person carries around with her/himself are discussed. In sum, some pithy questions highlight the view that changed managerial attitudes, more innovative staff development techniques, and changed practice interventions are needed to obviate an intractable wrong.  相似文献

ObjectiveTo undertake a structured review of the literature to determine the effect of antenatal education on labour and birth, particularly normal birth.MethodOvid Medline, CINAHL, Cochrane and Web of Knowledge databases were searched to identify research articles published in English from 2000 to 2012, using specified search terms in a variety of combinations. All articles included in this structured review were assessed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA).FindingsThe labour and birthing effects on women attending antenatal education may include less false labour admissions, more partner involvement, less anxiety but more labour interventions.ConclusionThis literature review has identified that antenatal education may have some positive effects on women's labour and birth including less false labour admissions, less anxiety and more partner involvement. There may also be some negative effects. Several studies found increased labour and birth interventions such as induction of labour and epidural use. There is contradictory evidence on the effect of antenatal education on mode of birth. More research is required to explore the impact of antenatal education on women's birthing outcomes.  相似文献
