Despite theoretical consensus that marriage markets constrain mate‐selection behavior, few studies directly evaluate how local marriage‐market conditions influence intermarriage patterns. Using data from the American Community Survey, the authors examine what aspects of marriage markets influence mate selection, assess whether the associations between marriage‐market conditions and intermarriage are uniform by gender and across pan‐ethnic groups, and investigate the extent to which marriage‐market conditions account for group differences in intermarriage patterns. Relative group size is the most salient and consistent determinant of intermarriage patterns across pan‐ethnic groups and by gender. Marriage‐market constraints typically explain a larger share of pan‐ethnic differences in intermarriage rates than individual traits, suggesting that scarcity of co‐ethnic partners is a key reason behind decisions to intermarry. When faced with market constraints, men are more willing or more successful than women in crossing racial and ethnic boundaries in marriage.  相似文献

To inform source attribution efforts, a comparative exposure assessment was developed to estimate the relative exposure to Campylobacter, the leading bacterial gastrointestinal disease in Canada, for 13 different transmission routes within Ontario, Canada, during the summer. Exposure was quantified with stochastic models at the population level, which incorporated measures of frequency, quantity ingested, prevalence, and concentration, using data from FoodNet Canada surveillance, the peer‐reviewed and gray literature, other Ontario data, and data that were specifically collected for this study. Models were run with @Risk software using Monte Carlo simulations. The mean number of cells of Campylobacter ingested per Ontarian per day during the summer, ranked from highest to lowest is as follows: household pets, chicken, living on a farm, raw milk, visiting a farm, recreational water, beef, drinking water, pork, vegetables, seafood, petting zoos, and fruits. The study results identify knowledge gaps for some transmission routes, and indicate that some transmission routes for Campylobacter are underestimated in the current literature, such as household pets and raw milk. Many data gaps were identified for future data collection consideration, especially for the concentration of Campylobacter in all transmission routes.  相似文献

Analyzing nationally representative survey data collected in the United States in 2014 (n?=?1,932), we formulate and test a novel explanation for the educational gradient in depressive symptoms. We theorize that status as cultural capital drives this gradient in addition to well-established economic and social factors, via the feelings of cultural entitlement it inspires. Therefore, we use structural equation modeling to decompose the education effect. We demonstrate that in addition to economic (job security and income) and social factors (embeddedness in the neighborhood), cultural capital indeed accounts for the educational gradient in depressive symptoms via cultural entitlement. We conclude that for understanding social gradients in mental health it is vital to be sensitive for the cultural mechanisms that status as cultural capital can inspire. Based on our findings we propose suggestions for further research.  相似文献

Player transgressions in sport relate to on- or off-field incidents that are out of the ordinary and may bring negative repercussions for stakeholders as a result of their association with the team, athlete or sport. Based on a series of depth interviews conducted with executives representing major Australian team-based sporting organizations, this paper outlines the effects that these incidents can have on relationships with sponsors from a sport organization perspective. The findings serve to develop a conceptual model that illustrates that the impact of transgressions is determined by a number of factors, which are discussed. The paper further presents a number of implications for the sport organization's public relations strategy, given that the role of public relations has evolved from primarily a communications focus to a more strategic management of relationships with various publics and stakeholders.  相似文献

Summary Despite a debate lasting some decades, there has been littleor no clear resolution about the way knowledge may be relatedto practice. To a considerable degree this is because of anassumption that knowledge is ‘knowledge as product’:given knowledge, researched and applied to practice. In recentyears, the concept of ‘knowledge as process’ hasemerged, focusing on knowledge of rigorous ways to think aboutpractice situations. This has generated a focus on hypothesisgeneration, testing and falsification, as well as lessons tobe learned from rigorous methods of qualitative analysis insocial research. Rigorous social workers, it has been suggested,would behave like ‘practical qualitative researchers ofthe individual instant’. However, there is little empiricalresearch on the matter. This paper evaluates process knowledgeforms used by social workers. It presents findings that socialworkers vary considerably in the extent to which they develophypotheses about the whole case, or aspects of it, in the depthwith which they analyse cases, and the systematic way they pursuean information gathering strategy. The paper concludes thatthere is clear evidence of social workers behaving as practicalqualitative researchers, but the rigour with which they do sovaries, with fundamental implications for the training process,and the extent to which rigorous strategies, along the linesof research methodology, should be taught.  相似文献

This paper examines market issues in the provision of children's services in the light of the changing role and practice of local authorities contracting for welfare services. In adult services, where there has been a legal requirement to reorganize on market lines, the services have had to modify some of their earlier contracting practices to take account of the complex requirements of health and welfare services and it is argued that relational contracting offers a more appropriate paradigm for these. Following the implementation of the Children Act 1989, although not a requirement of the Act, many of the organizational systems in relation to markets, originally developed for adult services, have been adopted for children's services. Two areas of services for children, day care and fostering services, are discussed in order to demonstrate that these contracting systems are inappropriate and often dysfunctional for the children concerned. It is argued that there is a widening gap between contracting systems in adult and children's services which needs to be addressed. In general, it is concluded that the philosophies of the market place are flawed when applied to children's services.  相似文献

Resource recovery from end-of-life (EOL) products is becoming increasingly engaged in by companies as a response to customer, consumer, government and social pressures, the electronics industry cites competitor pressures as being the main driver of EOL product take-back and recovery. Recovery can occur at three levels; i.e. product, part and material. Each of these options has economic and environmental advantages and disadvantages depending on the product type and a host of other influencing factors. The work described in this paper supports the decision as to the most favourable route from a cost and value perspective, a software model that provides such support is also described.  相似文献

European Union legislation, and existing national legislation of many European countries, mandates that manufacturers take back and recover their electronic and electrical equipment. If manufacturers are to comply with legislation, models need to be developed for these activities. Whilst infrastructural and technological deficits exist and must be addressed, so too must the organization of recovery, from a business perspective. In this paper, models of resource recovery are presented and a case study described.  相似文献
