This paper assesses the impact of three main destabilizing factors on marital stability in Cambodia: the radical reformation of marriage under the Khmers Rouges (KR); the imbalanced gender ratio among marriageable adults resulting from gendered mortality during the KR regime; and, after decades of isolation from the West, a period of rapid social change. Although there is evidence of declining marital stability in the most recent period, marriages contracted under the KR appear as stable as adjacent marriage cohorts. Thesefindings suggest that the conditions under which spouses were initially paired matter less for marital stability than does their contemporaneous environment.  相似文献

A product has been formally denned as being subject to sudden obsolescence if its lifetime is negative exponentially distributed. Using an approximate model, Masters suggested that the traditional method of incorporating obsolescence cost as a component of inventory holding costs in the economic order quantity (EOQ) model was appropriate-for products subject to sudden obsolescence, provided that the obsolescence cost component was computed properly. Unfortunately, current practice of the EOQ model seriously underestimates the costs of sudden obsolescence. An exact model demonstrating that Masters' model also underestimated true lifetime costs and overestimated the optimal order quantity has been presented. Neither of these models addressed quantity discounts. Furthermore, with their cost-minimization focus, these models fail to identify situations when minimized costs exceed expected revenues. We extend Joglekar and Lee's model to focus on maximizing profits, rather than minimizing costs. This model answers such questions as whether to stock the product at all, whether to accept a quantity discount offer, and what order quantity to use. Numerical examples and sensitivity analyses suggest that Masters' model provides a significant improvement over the traditional model in moving toward true optimality. However, they also illustrate situations where both the traditional and the Masters' model accept a quantity discount that deserves to be rejected and stock a product that should not be stocked. In such situations, it seems important that a retailer uses the profit-maximization model presented here.  相似文献

We investigate the performance of capacity-sensitive order review and release (ORR) procedures in job shop environments that have not been previously explored. Previous research has ignored the case of job shops which must perform to very tight due-dates because of time-sensitive customers. We propose and test a new capacity sensitive ORR procedure called path based bottleneck (PBB) in such environments, along with the modified infinite loading (MIL) procedure which has been shown to work well in several studies. We compare the performance of these two controlled release rules with that of immediate release rule under different conditions of capacity utilization and customer specified exogenous duedates. Our results indicate that PBB performs well in lowering total costs when due-dates are tight, while MIL is a better procedure with relatively loose to medium due-dates. We also show that in many cases, the shortest processing time (SPT) dispatching rule is a superior performer than a due-date based rule like critical ratio (CR); a conclusion which is contrary to the existing research in this area. In addition, the shop floor control policies recommended are shown to be sensitive to the cost structure of the firm. The managerial implications of this research in providing effective shop floor control in job shops operating under tight due-date conditions are also discussed.  相似文献

In the United States today, Muslim identity is highly stigmatized. Much of this can be attributed to an increasing climate of Islamophobia. The current study finds that some Muslim Americans are confronted with another source of stigma: other Muslims. Using interview data with 23 Muslim Americans in and around Houston, TX, this study examines the intersection of religious out‐group and in‐group stigma in the lives of Muslim Americans. Findings suggest that stigma comes not only from non‐Muslims, but also from other Muslims. Some Muslim Americans are especially vulnerable to religious in‐group stigma. Those who are most acculturated to non‐Muslim, Western culture often face criticism from Muslim communities, be they inside or outside the United States. These Muslim Americans find that they are not perceived as fully Muslim or fully American, and therefore denied the full benefits of either status while simultaneously bearing the burden of both. This paper articulates the multiple dimensions of stigma faced by Muslims in America.  相似文献

Various approaches to personalisation are well-established in the UK social care sector and are now starting to ‘travel’ to other sectors. In this paper we report findings from an evaluation of a pilot to test elements of personalisation in the management of offenders in probation services within the English criminal justice system. Following a review of evidence from social care, three different approaches to personalised-practice were developed and tested on a small-scale in three separate sites. The evaluation finds that all three approaches were implemented reasonably successfully, but challenges were identified including that personalised approaches are more time-consuming, that staff need support to exercise professional discretion and that balancing greater choice with managing criminogenic risk requires new ways of conceptualising the relationship between case manager and service user. Overall, ‘deeper’ approaches to personalisation, such as co-production, will take time to emerge. This paper makes two important contributions to the debate on personalisation in public services. First, it addresses the question of how transferable the concept of personalisation is from the social care sector to other sectors in the UK, in this case the criminal justice system. Secondly, it outlines a methodology for developing and evaluating personalisation pilots, prior to a wider roll-out.  相似文献

Career counselors must continually enhance their knowledge and skills to assist clients contemplating careers in science, technology, engineering, and mathematics (STEM). Therefore, the authors review STEM disciplines and theory‐driven strategies for assisting diverse individuals to explore, enter, and persist in STEM careers. Appropriate use of career assessments can contribute greatly to this effort. To identify available measures for STEM‐focused domains and constructs, the authors conducted a journal content analysis of stand‐alone STEM‐related career assessments from 1983 to 2016, identifying 39 articles with 153 measures. Notable results included the emergence of social cognitive theory and social cognitive career theory as prevailing frameworks for instrument development, a wide variety of disciplines and journals represented, an underrepresentation of minority samples, and untapped potential for cross‐discipline and researcher–practitioner collaboration. Useful strategies and resources for counselors and recommendations for enhancing career assessments and interventions are addressed.  相似文献

This study examines the impact of ancillary health and social services matched to client needs in substance abuse treatment for African Americans, Latinos and Whites. The study uses data collected from 1992 to 1997 for the National Treatment Improvement Evaluation Study, a prospective cohort study of substance abuse treatment programs and their clients. The analytic sample consists of 3142 clients (1812 African Americans, 486 Latinos, 844 Whites) from 59 treatment facilities. Results show that racial/ethnic minorities are underserved compared to Whites in the substance abuse service system. Different racial/ethnic groups come into treatment with distinct needs and receive distinct services. Although groups respond differentially to service types, substance abuse counseling and matching services to needs is an effective strategy both for retaining clients in treatment and for reducing post-treatment substance use for African Americans and Whites. Receipt of access services was related to reduced post-treatment substance use for Latinos. Study findings are relevant to planning special services for African Americans and Latinos.  相似文献
