The authors review the recent empirical and theoretical literature on physician-assisted dying (PAD) since implementation of the Oregon Death With Dignity Act (ODDA) in 1997. The authors provide a brief overview of end-of-life practices; consider ethical and practical issues regarding PAD; outline governments' acts and health care organizations' current codified principles regarding PAD, including the American Psychological Association's goal to increase the visibility of psychology in end-of-life issues; examine recent data pertinent to ODDA implementation and psychologists' attitudes regarding PAD; and outline potential roles for health psychologists responding to requests for PAD and implementing PAD (where it is legal). Health psychologists can assume at least 4 roles regarding PAD: (a) policy advocates, (b) educators, (c) practitioners, and (d) researchers.  相似文献

While previous research has mainly emphasised the importance of leader–member exchange (LMX) to job satisfaction, there is a lack of research on reciprocal relationships between job satisfaction and LMX. In this study, we not only suggest that good LMX increases job satisfaction, but that job satisfaction can also enhance high‐quality supervisor–employee relationships. A full cross‐lagged panel analysis was used to test reciprocal relationships between LMX and job satisfaction. Employees (N= 279) of a large information technology company filled out questionnaires at two times, with a time lag of 3 months. In line with our predictions, findings revealed a positive relationship between LMX and job satisfaction both at Time 1 and Time 2. Moreover, LMX at Time 1 predicted the increase of job satisfaction at Time 2, and job satisfaction at Time 1 predicted the increase of LMX at Time 2. The results demonstrate the need to consider reciprocal relationships between job satisfaction and LMX when explaining employees' workplace outcomes. Our findings are discussed in terms of positive psychology theory.  相似文献

Abstract

As more organizations implement multinational strategies, sales managers leading sales forces encounter complex cultural challenges that affect relationships, processes, and outcomes. We undertake a qualitative study with the objective of understanding the sales manager–salesperson relationship when the sales manager is leading sales representatives located in other cultures. Because of the significant size and growth of Asian countries, we focus our study on the Asia-Pacific Rim region. In-depth interviews conducted with 21 sales managers working for a large multinational technology firm in our focal region provide the data for our analysis. Using a grounded theory approach, we identify five key themes: building and sustaining cross-cultural relationships, cross-cultural communication effectiveness, acquisition and maintenance of trust across cultures, language, and decision-making. From our findings, research propositions are offered and implications for researchers and practitioners are discussed.  相似文献

We carried out a randomized controlled trial to determine whether an intensive intervention after a suicide attempt could decrease by half the risk of a repeat attempt in the following two years. After initial assessment and randomization, experimental subjects attended 18 therapy appointments over one year, including one home visit, and measures to improve attendance. Control subjects received the usual care. Of 63 experimental subjects, 35% made a repeat attempt, and so did 30% of 63 control subjects. The study had a 99% power to detect the desired decrease of risk (30% to 15%). Clearly, the intervention did not achieve its objective.  相似文献
