(with an introduction by Daniel L. McFadden) The past and the present processes leading to social security legislation inform expectations regarding the future of social security, and with international comparisons, provide lessons to those who would learn them. (JEL H55)  相似文献

Many faculty members consider using case studies but not all end up using them. We provide a brief review of what cases are intended to do and identify three ways in which they can be used. We then use an example to illustrate how we have used the case study method in teaching business demography. Among other benefits, we note that the case studies method not only encourages the acquisition of skills by students, but can be used to promote “deep structure learning,” an approach naturally accommodates other features associated with the case studies method—the development of critical thinking skills, the use of real world problems, the emphasis of concepts over mechanics, writing and presentation skills, active cooperative learning and the “worthwhileness” of a course. As noted by others, we understand the limitations of the case study method. However, given its strengths, we believe it has a place in the instructional toolbox for courses in business demography. The fact that courses we teach is a testament to our perceived efficacy of this tool.  相似文献

Demographic disparities between the rates of occurrence of an adverse economic outcome can be observed to be increasing even as general social improvements supposedly lead towards the elimination of the adverse outcome in question. Scanlan (Chance 19(2):47–51, 2006) noticed this tendency and developed a ‘heuristic rule’ to explain it. In this paper, we explore the issue analytically, providing a criterion from stochastic ordering theory under which one of two demographic groups can be considered disadvantaged and the other advantaged, and showing that Scanlan’s heuristic obtains as a rigorous finding in such cases. Normative implications and appropriate social policy are discussed.  相似文献

There are few published articles on conducting large‐scale surveys in secondary schools, and this paper seeks to fill this gap. Drawing on the experiences of the Youth On Religion project, it discusses the politics of gaining access to these schools and the considerations leading to the adoption and administration of an online survey. It is concluded that successful research in schools has to be planned carefully in collaboration with key members of staff, and justified as an educational activity. Providing speedy feedback was helpful to ensure schools benefited from the research and to keep them engaged with the project. © 2011 The Author(s).

Most words that infants hear occur within fluent speech. To compile a vocabulary, infants therefore need to segment words from speech contexts. This study is the first to investigate whether infants (here: 10‐month‐olds) can recognize words when both initial exposure and test presentation are in continuous speech. Electrophysiological evidence attests that this indeed occurs: An increased extended negativity (word recognition effect) appears for familiarized target words relative to control words. This response proved constant at the individual level: Only infants who showed this negativity at test had shown such a response, within six repetitions after first occurrence, during familiarization.  相似文献

It has been estimated that 80% of Australians engage in some form of gambling, with approximately 115,000 Australians experiencing severe problems (Productivity Commission 2010). Very few people with problem gambling seek help and, of those who do, large numbers drop-out of therapy before completing their program. To gain insights into these problems, participants who had either completed or withdrawn prematurely from an individual CBT-based problem gambling treatment program were interviewed to examine factors predictive of premature withdrawal from therapy as well as people??s ??readiness?? for change. The results indicated that there might be some early indicators of risk for early withdrawal. These included: gambling for pleasure or social interaction; non-compliance with homework tasks; gambling as a strategy to avoid personal issues or dysphoric mood; high levels of guilt and shame; and a lack of readiness for change. The study further showed that application of the term ??drop-out?? to some clients may be an unnecessarily negative label in that a number appear to have been able to reduce their gambling urges even after a short exposure to therapy.  相似文献

The placement of nasogastric (NG) tubes is known to be prone to error and may lead to serious issues for patient safety and wellbeing. In some instances these have been catastrophic and resulted in the death of the patient. This study sought to explore the potential risks associated with this procedure through the use of systematic prospective risk assessment. The research team used the Prospective Hazard Analysis (PHA) toolkit developed by Ward et al (2010) . The study has shown a wide number of risks that cover equipment design, work organisation, and training issues. The link between equipment design and training provides an important example of the need for a systematic approach to reducing errors and improving resilience in this aspect of healthcare.  相似文献

In this study we examine whether the Work Ability Index (WAI) has additional value in predicting long-term absenteeism in construction industry. Results of the study show that the WAI has additional value in predicting absenteeism, but that the amount of explained variance is low. This is partly due to the definition of absenteeism in The Netherlands, where this study took place.  相似文献
