Relocation, as an issue in the context of family law, typically involves the proposed move of a separated or divorced parent with a child to a new residence a substantial distance away from the non-moving parent. Based on a comprehensive review of the empirical evidence, 11 studies that focused on relocation within the context of separation and divorce were located, retrieved and appraised based on a common standard for assessing the methodological quality of the studies. Results of the critical appraisal found that the majority of social science research studies on relocation are of poor quality. Overall, the project’s findings demonstrate the need to move away from oversimplified considerations for relocation and to embrace a more comprehensive approach to fully capture the various factors that are relevant when considering the strengths and limitations of relocation.  相似文献

This study examines contemporary trends in Black Church adult participation and whether and how patterns are influenced by factors such as denomination, location, church and clergy profile, church environment, and programmatic efforts. Bivariate and ordered logit results based on Faith Factor 2000 Project data across seven denominations suggest minimal denominational influence; however, church environment, including worship features and sermonic emphasis, as well as varied programs, positively influence participation. Additionally, participation decline is apparent among rural congregations. Results help illumine profiles of Black churches most likely to experience high or low levels of participation.  相似文献

We surveyed National Science Foundation (NSF)-funded research in Mississippi to determine the economic extent of research damage and delays due to Hurricane Katrina. While several facilities were physically damaged, we found that the largest effects were time delays and missed opportunities. While psychological factors were not part of the original economic impact study, it became clear that they played an important role. Specifically, the Principal Investigator's (PI's) attitude of “just another delay” was one cultural barrier to fully accounting for the cost of these research delays. We concluded that Principal Investigators, with the assistance of funding agencies, should be better trained to measure time and opportunity costs associated with their research, so future disaster recovery efforts can more fully address those needs.  相似文献

In 2007–2008 the Council of Australian Governments agreed to six ambitious targets for addressing longstanding disparities between Indigenous and other Australians in health, education and employment outcomes. The ‘National Integrated Strategy for Closing the Gap on Indigenous Disadvantage’ (colloquially ‘Closing the Gap’) includes the goal of eliminating life expectancy gaps within a generation. This policy says nothing about what changes in the demographic structure of the population might be expected should there be even partial success towards this ambitious target. Information is required to analyse age and sex shifts for their effects on service demand and provision. In this study we apply cohort component projections modelling to the Northern Territory, the Australian jurisdiction with the largest Indigenous component in its population and the largest life expectancy gaps, to assess the demographic effects of closing the gap within a generation. Three scenarios are modelled: (1) No changes to Indigenous life expectancies from those estimated in 2010; (2) Complete success in closing the gap within a generation; and (3) A continuation of current forecasts about how Indigenous life expectancies will change into the future. Although closing the gap would only produce a small increase in the size of the next generation’s Indigenous population, over and above that projected with lower life expectancy scenarios, it would result in substantial changes in age compositions, with associated shifts in various demographic indices. These are pertinent to the planning and funding of core services into the future.  相似文献

Information and communication technologies hold much promise for use in education in developing countries. This study reports on an evaluation conducted on the introduction of computers in the delivery of the mathematics curriculum in one of the provinces of South Africa. Although the request was for an outcome evaluation very early in the implementation of the program, it was tailored in such a way as to fulfill a more formative role. Despite substantial variability in implementation, and in most cases with very weak exposure of the learners to the intervention, sufficient evidence emerged to indicate that this mode of curriculum delivery may be effective. Improvement in mathematics performance was related to a range of variables: some concerned classroom teaching practices, some referred to social differences between the learners, and some to the specific intervention. The strongest of these predictors in the sample was the strength of the intervention: the more time learners spent on using the software to study mathematics, the more improvement they showed from 1 year to the next in their performance in the subject.  相似文献

A random telephone survey was conducted with a representative sample of 2,274 U.S. residents aged 14–21. The prevalence of problem gambling, as measured by the SOGS-RA, was 2.1%. Sixty-eight percent (68%) of the respondents had gambled in the past year, and 11% had gambled more often than twice per week. Males had much higher gambling involvement than females, and gambling involvement increased among older respondents. Blacks were less likely than average to have gambled in the past year, but if they gambled, they were more likely to do so frequently. Low SES respondents were less likely to have gambled in the past year, but if they gambled, they were more likely to be problem gamblers. Life transitions that are associated with assuming adult roles (employment, living independently of parents, non-student status) are also associated with greater gambling involvement. The rates of problem and pathological gambling were lower than those in an adult survey conducted earlier, when measured with the same questionnaire.  相似文献

Two representative U.S. telephone surveys of gambling were conducted—an adult survey of adults aged 18 years and older (n = 2,631) and a youth survey of young people aged 14–21 years old (n = 2,274). Because the questions and methods were the same or similar in both surveys, the data from these two surveys were combined into a single dataset to examine the prevalence and sociodemographic correlates of gambling and problem gambling across the lifespan. The present work focused specifically on gambling on the lottery which is the most prevalent form of gambling in the U.S. The frequency of gambling on the lottery increased sharply from mid adolescence to age 18 which is the legal age to purchase lottery tickets in most states; lottery play continued to increase into the thirties when it leveled off and remained high through the sixties and then decreased among those 70 years and older. Considering multiple sociodemographic factors together in a negative binomial regression, the average number of days of lottery gambling was significantly predicted by male gender, age, neighborhood disadvantage and whether or not lottery was legal in the state where the respondent lived. These findings can be used to inform policies regarding lotteries in the U.S.  相似文献

Both a resource-based view and transaction cost economics perspective point to firms deciding to either make-or-buy an input. In practice, this tends to result in low-skill functions being outsourced while those of higher value are retained. In this article, we explore a situation counter to the prevailing literature. We study a highly creative industry – fashion – and discover the relationship between core competence and outsourcing is not as simple as previously conceptualised. Creativity, fashion's assumed competency, rather than being guarded within a firm is instead often outsourced or borrowed. More mundane tasks such as marketing and logistics are what each firm rather develops. The effects of resulting co-dependencies are mapped and analysed in order to offer managerial insight as well as contribute to discussion within the outsourcing and resource based literatures.  相似文献
