Our study uses qualitative and interpretative design to analyse what hybrid nurse middle managers do in their managerial practice, what affects this, and to what effect, focusing upon implementing policy‐driven guidelines on the clinical frontline. Examining two comparative hospital cases and drawing upon Scandinavian institutionalism, we conceive their role as one of ‘translation’. On the one hand, they exhibit strategic agency. On the other hand, their managerial role not only influences, but is influenced by, professional and managerial hierarchies. In both hospitals, in the short term we see how hybrid nurse middle managers are able to mediate professional and managerial hierarchies and implement clinical guidelines through translational work. However, in one case, they less effectively accommodate policy‐driven, managerial pressure towards compliance with government regulations and financial parsimony. In this case, the outcome of their translational work is not sustained in the longer term, as professional and managerial hierarchies reassert themselves. Drawing upon the example of their managerial role in healthcare, we highlight that hybrid middle managers enact a strategic translational role and outline situational constraints that impact this more strategic role.  相似文献

The enterprise of science and engineering (S&E) is powerfully affected by the role of immigrants in institutions of higher education and in US labour markets (Freeman et al., 2004). Especially since the 1970s and increasingly in the 1990s, educational institutions and labour markets have experienced steady increases of foreign students and workers and have come to expect more of the same. Yet, since 2001 there have been notable downturns in the number of foreign students applying and attending US institutions of higher education.  相似文献

Twenty years ago, the National Institute of Child Health and Human Development (NICHD) issued a request for proposals that resulted in the National Survey of Families and Households (NSFH), a unique survey valuable to a wide range of family scholars. This paper describes the efforts of an interdisciplinary group of family demographers to build on the progress enabled by the NSFH and many other theoretical and methodological innovations. Our work, also supported by NICHD, will develop plans for research and data collection to address the central question of what causes family change and variation. We outline the group's initial assessments of orienting frameworks, key aspects of family life to study, and theoretical and methodological challenges for research on family change. Finally, we invite family scholars to follow our progress and to help develop this shared public good.  相似文献

In order to explain persistent racial inequality, researchers have posited that black Americans receive fewer job benefits from their social networks because of their reluctance to provide assistance to others who are looking for work. We test this idea on a national scale using geo‐coded data from the General Social Survey. Our results show that, on average, blacks offer more frequent job‐finding assistance to their friends than do whites. However, additional analyses reveal that race‐based job‐finding assistance is context dependent, as blacks living in areas characterized by concentrated black poverty have lower odds of helping others search for jobs than members of other races and in other community contexts.  相似文献

The relationship among religion, education and social mobility in Scotland is analysed statistically using the Scottish Household Survey of 2001 . The large sample size allows much greater statistical power for this purpose than any previous source, and thus allows a more reliable assessment of claims that the stratifying effect of religion in Scotland may have declined. The questions investigated are as follows. What are the religious differences in the distributions of class origins and class destinations, in the movement between these (absolute mobility), and in the association of these (relative mobility, or social fluidity)? Do changes in social fluidity across cohorts vary among people with different religious affiliation? Are there religious differences in the association of origins and education, in the association of education and destinations, or in the role of education in social fluidity, and do any of these vary over cohorts? The conclusions are that, in younger cohorts, there is no religious difference in social status, and that in older cohorts Catholics are generally of lower status than Protestants and the non‐religious. Social fluidity does not, however, vary among religious groups, even for older cohorts, and does not change over time. The reason for convergence in social status of religious groups over time is probably the equalizing of educational attainment among the groups: there is no evidence for any of the cohorts that the labour‐market rewards to education differ by religion.  相似文献

The effects of urban disturbance are critical to understand, as the majority of the world??s population now resides in urban centers. For example, urbanization often leads to reduced species diversity at the expense of a few urban-adapted taxa. However, it remains unclear why some taxa thrive following human disturbance whereas others do poorly. The western black widow spider, Latrodectus hesperus, thrives in disturbed, urban habitat??often forming dense aggregations (i.e., infestations) relative to typical low-density, desert populations. We examined the population dynamics of ten black widow aggregations spread across metropolitan Phoenix, AZ, during the peak of the breeding season (June?CAugust). Here we show that prey abundance, female mass, web volume and population density exhibit minimal temporal variation across the breeding season, but that prey abundance, female mass and population density show significant spatial variation across the ten urban aggregations. Our measure of prey abundance and foraging success, the number of prey carcasses found in black widow webs, shared a strong positive relationship with female mass and population density, but not with web volume. Surprisingly, female mass, web volume and population density were not correlated with each other. The abiotic variables we measured at each site did a poor job of explaining black widow population parameters, although we did find a marginal trend for more recent developments to harbor denser black widow aggregations. Our findings support the generalization that urbanization heightens spatial variation, and we suggest that local urban prey abundance is influential in promoting urban infestations full of heavy, fecund female black widows. Studies of the population ecology of urban pests are necessary to identify the mechanisms allowing some species to thrive following human disturbance while much native biodiversity is lost following urbanization.  相似文献

Research suggests that body image and sexual behaviors are related, with poor body image associated with risky behaviors and positive body image related to protective behaviors. However, few studies explore the relationships between positive body image and contraceptive use. Accordingly, the current study investigated the relationship between body appreciation and barrier and hormonal contraceptive use among college women (N = 399). Body appreciation was significantly related to male condom use and to the use of both male condoms and a hormonal contraceptive. These findings are promising as dual contraceptive use is the best way to prevent unintended pregnancy and sexually transmitted infections (STIs).  相似文献
