AbstractEfforts to professionalize the field of bioethics have led to the development of the Healthcare Ethics Consultant-Certified (HEC-C) Program intended to credential practicing healthcare ethics consultants (HCECs). Our team of professional ethicists participated in the inaugural process to support the professionalization efforts and inform our views on the value of this credential from the perspective of ethics consultants. In this paper, we explore the history that has led to this certification process, and evaluate the ability of the HEC-C Program to meet the goals it has set forth for HCECs. We describe the benefits and weaknesses of the program and offer constructive feedback on how the process might be strengthened, as well as share our team’s experience in preparing for the exam. 相似文献

This project investigates the relationship between religious involvement and women's work and family pathways in the United States. I identify five work-family configurations using National Longitudinal Study of Youth 1979 (NLSY79) data and latent class analysis. These configurations incorporate cohabitation histories, timing of family formation, and maternal employment. Then, I analyze how adolescent religiosity and personal and family characteristics are associated with subsequent work-family pathways. Affiliation with an evangelical Protestant tradition is associated with women who form families early, while Catholic affiliation is tied to later family formation. Importantly, family background characteristics such as living with both biological parents and higher parental education, as well as race/ethnicity and the respondent's educational attainment, are the most consistent variables associated with work-family configurations. These results suggest that religious involvement, when considered alongside family background, contributes to women's unequal work-family pathways in adulthood. The close links between religion, family, and stratification are evident in the study of women's work-family experiences. 相似文献

A computational model of sequence learning is described that is based on pairwise associations and generalization. Simulations by the model predicted that rats should learn a long monotonic pattern of food quantities better than a nonmonotonic pattern, as predicted by rule-learning theory, and that they should learn a short nonmonotonic pattern with highly discriminable elements better than 1 with less discriminable elements, as predicted by interitem association theory. In 2 other studies, the model also simulated behavioral "rule generalization," "extrapolation," and associative transfer data motivated by both rule-learning and associative perspectives. Although these simulations do not rule out the possibility that rats can use rule induction to learn serial patterns, they show that a simple associative model can account for the classical behavioral studies implicating rule learning in reward magnitude serial-pattern learning. 相似文献

A confirmatory approach to the factor structure of the Boredom Proneness Scale: evidence for a two-factor short form 总被引:1,自引:0,他引:1
We analyzed previous exploratory factor analytic structures on the Boredom Proneness Scale (BPS; Farmer & Sundberg, 1986) using confirmatory factor analysis in structural equation modeling in LISREL 8 (J?reskog & S?rbom, 1993). These analyses indicated that 2 factors were generally consistent across 6 exploratory models. Items that had significant loadings on these two factors (N = 12; 6 for each factor) indicated a lack of Internal Stimulation and External Stimulation. In further analysis on these 12 items using LISREL, we found a much improved fit and provided support for a short form version of the original BPS. We also found the shortened version to be invariant across gender. We discuss implications for the more precise measurement of boredom proneness and the use of the scale in applied settings. 相似文献
