ABSTRACTSocial work educators are exploring the benefits of mindfulness training for social work pedagogy. The authors evaluate the outcomes of a mindfulness program for MSW students. The authors assessed changes in mindfulness, self-compassion, affect, mood, and impairment due to emotional distress before and after the program, and at 4-month follow-up. The authors examine how the group process may facilitate the development of mindfulness and consider how mindfulness practices can support group development and student learning. Results demonstrate that mindfulness training supports student self-regulation and well-being and suggest that the active ingredients of the group process may play a role in mindfulness training outcomes. 相似文献

Service operations that utilize cross-trained employees face complex workforce staffing decisions that have important implications for both cost and productivity. These decisions are further complicated when cross-trained employees have different productivity levels in multiple work activity categories. A method for policy analysis in such environments can be beneficial in determining low-cost staffing plans with appropriate cross-training configurations. In this paper, we present an integer linear programming model for evaluating cross-training configurations at the policy level. The objective of the model is to minimize workforce staffing costs subject to the satisfaction of minimum labor requirements across a planning horizon of a single work shift. The model was used to evaluate eight cross-training structures (consisting of 36 unique cross-training configurations) across 512 labor requirement patterns. These structures, as well as the labor requirement patterns, were established based on data collected from maintenance operations at a large paper mill in the United States. The results indicate that asymmetric cross-training structures that permit chaining of employee skill classes across work activity categories are particularly useful. 相似文献

This article considers designed experiments for stability, comparability, and formulation testing that are analyzed with regression models in which the degradation rate is a fixed effect. In this setting, we investigate how the number of lots, the number of time points and their locations affect the precision of the entities of interest, leverages of the time points, detection of non-linearity and interim analyses. This investigation shows that modifying time point locations suggested by ICH for stability studies can significantly improve these objectives. In addition, we show that estimates of precision can be biased when a regression model that assumes independent measurements is used in the presence of within-assay session correlation. This bias can lead to longer shelf life estimates in stability studies and loss of power in comparability studies. Mixed-effect models that take into account within-assay session correlation are shown to reduce this bias. The findings in this article are obtained from well known statistical theory but provide valuable practical advice to scientists and statisticians designing and interpreting these types of experiments. 相似文献

Because of their multimodality, mixture posterior distributions are difficult to sample with standard Markov chain Monte Carlo
(MCMC) methods. We propose a strategy to enhance the sampling of MCMC in this context, using a biasing procedure which originates
from computational Statistical Physics. The principle is first to choose a “reaction coordinate”, that is, a “direction” in
which the target distribution is multimodal. In a second step, the marginal log-density of the reaction coordinate with respect
to the posterior distribution is estimated; minus this quantity is called “free energy” in the computational Statistical Physics
literature. To this end, we use adaptive biasing Markov chain algorithms which adapt their targeted invariant distribution
on the fly, in order to overcome sampling barriers along the chosen reaction coordinate. Finally, we perform an importance
sampling step in order to remove the bias and recover the true posterior. The efficiency factor of the importance sampling
step can easily be estimated a priori once the bias is known, and appears to be rather large for the test cases we considered. 相似文献

Abstract Seven focus groups at a university campus were formed to identify college men's health concerns, barriers to seeking help, and recommendations to help college men adopt healthier lifestyles. Content analysis was used to identify and organize primary patterns in the focus-group data. Results of the study revealed that the college men were aware that they had important health needs but took little action to address them. The participants identified both physical and emotional health concerns. Alcohol and substance abuse were rated as the most important issues for men. The greatest barrier to seeking services was the men's socialization to be independent and conceal vulnerability. The most frequently mentioned suggestions for helping men adopt healthier lifestyles were offering health classes, providing health information call-in service, and developing a men's center. Implications of the results are discussed. 相似文献
