Analyses of disordered gambling assessment data have indicated that commonly used screens appear to measure latent categories. This stands in contrast to the oft-held assumption that problem gambling is at the extreme of a continuum. To explore this further, we report a series of latent class analyses of a number of prevalent problem gambling assessments (PGSI, SOGS, DSM-IV Pathological Gambling based assessments) in nationally representative British surveys between 1999 and 2012, analysing data from nearly fifty thousand individuals. The analyses converged on a three class model in which the classes differed by problem gambling severity. This identified an initial class of gamblers showing minimal problems, a additional class predominantly endorsing indicators of preoccupation and loss chasing, and a third endorsing a range of disordered gambling criteria. However, there was considerable evidence to suggest that classes of intermediate and high severity disordered gamblers differed systematically in their responses to items related to loss of control, and not simply on the most ‘difficult’ items. It appeared that these differences were similar between assessments. An important exception to this was one set of DSM-IV criteria based analyses using a specific cutoff, which was also used in an analysis that identified an increase in UK problem gambling prevalence between 2007 and 2010. The results suggest that disordered gambling has a mixed latent structure, and that present assessments of problem gambling appear to converge on a broadly similar construct. 相似文献

This study uses hazard function estimations and time‐series and cross‐sectional growth regressions to examine the impact of exit through merger and acquisition (M&A) or failure, and internally generated growth, on the firm‐size distribution within the U.S. credit union sector. Consolidation through M&A was the principal cause of a reduction in the number of credit unions, but impact on concentration was small. Divergence between the average internally generated growth of smaller and larger credit unions was the principal driver of the rise in concentration. (JEL G21) 相似文献

Schools, districts, and state-level educational organizations are experiencing a great shift in the way they do the business of education. This shift focuses on accountability, specifically through the expectation of the effective utilization of evaluative-focused efforts to guide and support decisions about educational program implementation. In as much, education leaders need specific guidance and training on how to plan, implement, and use evaluation to critically examine district and school-level initiatives. One specific effort intended to address this need is through the Capacity for Applying Project Evaluation (CAPE) framework. The CAPE framework is composed of three crucial components: a collection of evaluation resources; a professional development model; and a conceptual framework that guides the work to support evaluation planning and implementation in schools and districts. School and district teams serve as active participants in the professional development and ultimately as formative evaluators of their own school or district-level programs by working collaboratively with evaluation experts. The CAPE framework involves the school and district staff in planning and implementing their evaluation. They are the ones deciding what evaluation questions to ask, which instruments to use, what data to collect, and how and to whom results should be reported. Initially this work is done through careful scaffolding by evaluation experts, where supports are slowly pulled away as the educators gain experience and confidence in their knowledge and skills as evaluators. Since CAPE engages all stakeholders in all stages of the evaluation, the philosophical intentions of these efforts to build capacity for formative evaluation strictly aligns with the collaborative evaluation approach. 相似文献

This article examines a personal safety curriculum (Keeping Me Safe) offered to Standard Three students (mostly nine-year-olds) in five primary schools in Kuala Lumpur, Malaysia. Staff of the Malaysian NGO, Protect and Save the Children, Association of Selangor and Kuala Lumpur (P.S. The Children), facilitated six weekly one-hour sessions featuring games and role play to teach children about potentially unsafe situations and touches, and to develop appropriate safety strategies and skills to ask for help. The students (n = 261) and a control group (n = 184) completed a 25 item questionnaire before and after the program, and for the experimental group only, again two months later. The assessment was supplemented by observations of each session, student interviews, and parent and teacher focus groups. The experimental group students showed substantial gains on about two-thirds of the questionnaire items. However, a minority of the students failed to absorb key messages of the curriculum. Challenges to implementing prevention programs in Malaysia are discussed. 相似文献

Improving animal welfare is an important part of the development of the agricultural industry, particularly at a time when intensification and the encroachment of factory-style production systems is making the maintenance of human-animal relations increasingly difficult. Animal science deals with the issue of improving stockmanship by focusing on the relationships between attitudes and behaviour, under the premise that improved attitudes will lead to improved behaviour. From an analysis of 42 interviews with owners, sharemilkers and workers on dairy farms in New Zealand we present a different view, seeing behaviour instead as part of a self-reinforcing culture in which animals, humans and the physical structure all contribute to the development of farm specific ways of doing and being. We further suggest that changing one stockperson's attitude alone is insufficient to ensure a change in the culture as other actors – including animals and non-human actors – reinforce any existing culture that has developed, making both attitudinal and behavioural change difficult. We conclude by discussing the key importance of designing farm systems and structures that promote positive interactions between animals and humans and suggest that this, rather than simply promoting knowledge and attitudinal change, is likely to be the most effective way of maintaining stockmanship in the face of an industrialising agriculture. 相似文献

Conducting Large‐Scale Surveys in Secondary Schools: The Case of the Youth On Religion (YOR) Project
Nicola Madge Peter J. Hemming Anthony Goodman Sue Goodman Sarah Kingston Kevin Stenson Colin Webster 《Children & Society》2012,26(6):417-429
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).

Packaging and labeling play a crucial role awhile protecting medicaments and transmitting a range of crucial information to the users. Taking into account the scarcity of specific studies in this area, it was considered great the need for a comprehensive survey about customers' satisfaction when handling these containers. 相似文献

This is a review of walking tasks in the railroad environment, and the injuries that result from slips, trips, falls, or other acute or even non-traumatic exposures. The lack of federal regulations for railroad walkways has led several states to develop and enforce their own regulations. Support from the research literature for such regulations has come from biomechanical studies of the effects of walking on railroad ballast, which will be reviewed. 相似文献

We test whether job insecurity of parents and children affect children’s moving-out decisions. Macroeconomic estimates for
13 European countries over 1983–2004 show that coresidence increases by 1.7 percentage points (PP) following a 10 PP rise
in the share of youths perceiving their job to be insecure and declines by 1.1 PP following the same increment in insecurity
for older workers. Microeconometric evidence for Italy in the mid-1990s shows that the probability of moving out increases
by about half a percentage point for a one-standard-deviation increase in paternal insecurity and by one-third of a percentage
point for a one-standard-deviation decrease in children’s insecurity. 相似文献
