In this study, we examined the curricular and institutional characteristics of HRD master’s programmes in the United States. Our sample included 108 programmes in 100 institutions that were self-identified as HRD programmes. Among our findings: (1) fewer programmes were located in schools of education (44%) and more were located in schools of business (28%) than indicated by previous research; (2) there was greater homogeneity in curriculum among programmes in the same institutional locations (e.g. schools of education or schools of business) and greater variation among programmes in different institutional locations; (3) the curriculum of programmes located in schools of education tended to focus on traditional educational topics such as adult learning and instructional design, while the curriculum of programmes located in school of business tended to focus on management topics such as organization development, staffing and employment law. Our findings suggest that the nature of HRD as an academic subject varies with institutional location, as do the skill sets of students who graduate from HRD programmes. Future research should take these differences into account. 相似文献

The political, social and academic attention on migrant workers in China has been focused on the full-time worker while those who seek part-time work are rarely studied. We explore the effect of part-time day-labour employment of older migrants in an odd-job market in Linyi City. The medical, housing needs and available services for them are analysed. The Linyi government pioneered a program providing comprehensive services to part-time migrant workers, allowing this study to explore the strengths and weakness of the model. Building the appropriate social service industry competencies demands a joint effort from the government, community, organizations, researchers and enterprises. 相似文献

Many institutions of higher education are struggling with the problem of excessive alcohol consumption by students. Colleges and universities want to be ‘good neighbors’ in their communities and must limit legal and social risks that result from excessive alcohol consumption by students. At the same time, colleges and universities operate in an increasingly challenging marketplace where many prospective students seek out institutions with a ‘party school’ reputation. Thus, higher education institutions are finding it difficult to define and carry out alcohol reduction measures that satisfy all constituents. This article discusses the approach taken at the University of Wisconsin—La Crosse. UW-L is an institution that identified a serious alcohol consumption problem and had to address the problem in a community where high levels of alcohol consumption are socially and culturally condoned. The article profiles the UW-L community and discusses the campaign model and strategy chosen. Quantitative and qualitative measures of success are discussed, along with lingering issues of resistance. The article ends with a summary of current issues and future directions being taken by the campaign. 相似文献

The current study explored youths’ views of President Donald Trump using quantitative ratings and open‐ended responses from a diverse sample of 1,432 U.S. adolescents from three geographic regions. Adolescent demographic characteristics (i.e., gender, race, geographic location) were systematically associated with their views about Trump. Open‐ended responses demonstrated substantial variability in youths’ rationales for approving or disapproving of the president. Adolescents' attitudes were informed by knowledge of the president’s leadership attributes, political views and policies, and their own experiences. Findings indicate that adolescents draw upon and synthesize a broad range of information when formulating their political views and coordinate this knowledge with their own opinions and experiences when evaluating political figures. 相似文献

We analyze the computational efficiency of approximate Bayesian computation (ABC), which approximates a likelihood function by drawing pseudo-samples from the associated model. For the rejection sampling version of ABC, it is known that multiple pseudo-samples cannot substantially increase (and can substantially decrease) the efficiency of the algorithm as compared to employing a high-variance estimate based on a single pseudo-sample. We show that this conclusion also holds for a Markov chain Monte Carlo version of ABC, implying that it is unnecessary to tune the number of pseudo-samples used in ABC-MCMC. This conclusion is in contrast to particle MCMC methods, for which increasing the number of particles can provide large gains in computational efficiency. 相似文献

Using longitudinal data from the Fragile Families and Child Wellbeing Study (N = 4,701; 1998–2010), the authors studied whether the unemployment rate was associated with private financial transfers (PFTs) among urban families with young children and whether family income moderated these associations. They found that an increase in the unemployment rate was associated with greater PFT receipt and that family income moderated the association. Poor and near‐poor mothers experienced increases in PFT receipt when unemployment rates were high, whereas mothers with incomes between 2 and 3 times the poverty threshold experienced decreases. Simulations estimating the impact of the Great Recession suggest that moving from 5% to 10% unemployment is associated with a 9‐percentage‐point increase in the predicted probability of receiving a PFT for the sample as a whole, with greater increases in predicted probabilities among poor and near‐poor mothers. 相似文献

The decreased pressure in the cabin of a pressurised aircraft (typically equivalent to ~8000 ft) reduces the oxygen level so that the blood oxygen saturation of all occupants falls from >97% (normoxia) at sea-level to below 92% (mild hypoxia). Although exposure to mild hypoxia does not affect well-learned cognitive and motor performance of aircrew, it has been proposed that it can affect the performance of some complex cognitive performance tasks involving multiple demands typical of emergency tasks that may have to be performed by pilots. In order to simulate some of these complex cognitive demands, 25 student volunteers participated in an experiment which assessed performance of complex logical reasoning and and multiple memory tasks before and after 2 hours of exposure to normoxia and mild hypoxia. Performance for the more difficult components of the complex reasoning task, especially involving conflict decisions, were marginally significantly degraded by mild hypoxia. Since the effects were only marginally significant future studies should investigate the effects of mild hypoxia on more subtle complex decision-making tasks. 相似文献

The increasing concern of antibacterial resistance has been well documented, as has the relative lack of antibiotic development. This paradox is in part due to challenges with clinical development of antibiotics. Because of their rapid progression, untreated bacterial infections are associated with significant morbidity and mortality. As a consequence, placebo-controlled studies of new agents are unethical. Rather, pivotal development studies are mostly conducted using non-inferiority designs versus an active comparator. Further, infections because of comparator-resistant isolates must usually be excluded from the trial programme. Unfortunately, the placebo-controlled data classically used in support of non-inferiority designs are largely unavailable for antibiotics. The only available data are from the 1930s and 1940s and their use is associated with significant concerns regarding constancy and assay sensitivity. Extended public debate on this challenge has led to proposed solutions by some in which these concerns are addressed by using very conservative approaches to trial design, endpoints and non-inferiority margins, in some cases leading to potentially impractical studies. To compound this challenge, different Regulatory Authorities seem to be taking different approaches to these key issues. If harmonisation does not occur, antibiotic development will become increasingly challenging, with the risk of further decreases in the amount of antibiotic drug development. However with clarity on Regulatory requirements and an ability to feasibly conduct global development programmes, it should be possible to bring much needed additional antibiotics to patients. 相似文献
