Advocating acceptance, committed action, and value-guided behavior over experiential avoidance, Acceptance and Commitment Therapy (ACT) may aid lesbian, gay, bisexual and transgender (LGBT) clients affected by hetero/homonormative social pressure. By conceptualizing LGBT paradigms of internal/external control/responsibility (IC-IR; EC-IR; IC-ER; EC-IR), ACT may be adapted to a myriad of multicultural worldviews. This article presents locus of acceptance as the attributed worth of internal/external cues perceived necessary by the client to achieve self-acceptance. Recognizing visibility and isolation as recurrent LGBT issues, locus of acceptances balances identity as individual (internal acceptance) with identity as community (external acceptance). 相似文献

Work values might be proximal predictors of individuals' late‐career intentions because they serve as guiding principles for the selection, evaluation, and justification of vocational behavior. The purpose of this study was to examine the relationship between work values and post‐retirement work intentions. The authors investigated individual work values within the structure of 4 higher order values elaborated on by Schwartz et al. ( 2012 ). Relationships between work values and 4 types of post‐retirement work intentions were examined. Data from 1,071 employees of a German logistics company were used to test the hypotheses. The results of a structural equation model indicated that work values were differentially related to the 4 types of post‐retirement work intentions. The identified work value–work type combinations add to the literature on post‐retirement work. Practice implications for promoting positive individual and organizational outcomes are drawn from the results. 相似文献

In this paper, we study the characteristics and results of two different approaches to urban regeneration which we have termed ‘Metagovernance’ and ‘Pluricentric coordination’ following. We studied this through a comparative study of area-based, participatory urban regeneration projects in Denmark and Japan, representing each one approach. The paper aims to clarify results of the two approaches in terms of five aspects of urban regeneration, relevant to the process and results: (1) strategic spatial improvement, (2) influence of the legal system and transparency of the processes, (3) empowerment of citizens and diversity of participants, (4) innovative capacity (diversity and creativity of the projects) and (5) continuity and flexibility of the projects. The paper concludes that each approach has strengths and weaknesses and that each country can learn from the other to strengthen future participatory urban regeneration. 相似文献

ABSTRACTIn this paper, we are interested in nonparametric inference issues for stochastic damping hamiltonian systems under the fluctuation-dissipation condition. This condition relates the magnitude of the dissipative term and the magnitude of the random term. The precise balance between the drift term which removes energy in average and the stochastic term provided by the fluctuation-dissipation relation insures that the canonical measure is preserved by the dynamics. In this framework, it is possible to give an explicit construction of a Lyapunov function and thus to prove exponential ergodicity. Then, we consider various estimation procedures and provide also a numerical section, where simulations are conducted. 相似文献

This article takes a first look at the distribution of returns to education for people with disabilities, a particularly disadvantaged group whose labor market performances have not been well studied or documented. Using a nonparametric approach, we uncover significant heterogeneity in the returns to education for these workers, which is drastically masked by conventional parametric methods. Based on these estimates, we construct the Sharpe ratio of human capital investment (taking into account its substantial risk), and our results corroborate the claimed importance of human capital in improving these workers’ wages. Our stochastic dominance tests show that the returns to education for workers with disabilities, as a group, may have been affected more adversely in the most recent recession, relative to their non-disabled counterparts. 相似文献

This paper presents a model and an algorithm for scheduling a system in which parts are processed through a chemical processing tank line. The tank line is equipped with one piece of material-handling equipment. The tank line is modelled with a mixed integer linear programming formulation. The formulation is then used to develop a heuristic algorithm. The algorithm generates the optimum or near optimum schedule and is easy to apply in practice where no defectives are permitted. 相似文献

Listeria monocytogenes is a leading cause of hospitalization, fetal loss, and death due to foodborne illnesses in the United States. A quantitative assessment of the relative risk of listeriosis associated with the consumption of 23 selected categories of ready‐to‐eat foods, published by the U.S. Department of Health and Human Services and the U.S. Department of Agriculture in 2003, has been instrumental in identifying the food products and practices that pose the greatest listeriosis risk and has guided the evaluation of potential intervention strategies. Dose‐response models, which quantify the relationship between an exposure dose and the probability of adverse health outcomes, were essential components of the risk assessment. However, because of data gaps and limitations in the available data and modeling approaches, considerable uncertainty existed. Since publication of the risk assessment, new data have become available for modeling L. monocytogenes dose‐response. At the same time, recent advances in the understanding of L. monocytogenes pathophysiology and strain diversity have warranted a critical reevaluation of the published dose‐response models. To discuss strategies for modeling L. monocytogenes dose‐response, the Interagency Risk Assessment Consortium (IRAC) and the Joint Institute for Food Safety and Applied Nutrition (JIFSAN) held a scientific workshop in 2011 (details available at http://foodrisk.org/irac/events/ ). The main findings of the workshop and the most current and relevant data identified during the workshop are summarized and presented in the context of L. monocytogenes dose‐response. This article also discusses new insights on dose‐response modeling for L. monocytogenes and research opportunities to meet future needs. 相似文献
