Ethnographers from anthropology, sociology, and other disciplines have been at the forefront of efforts to bring gender into scholarship on international and transnational migration. This article traces the long and often arduous history of these scholars’ efforts, arguing that though gender is now less rarely treated merely as a variable in social science writing on migration, it is still not viewed by most researchers in the field as a key constitutive element of migrations. The article highlights critical advances in the labor to engender migration studies, identifies under‐researched topics, and argues that there have been opportunities when, had gender been construed as a critical force shaping migrations, the course of research likely would have shifted. The main example developed is the inattention paid to how gendered recruitment practices structure migrations – the fact that gender sways recruiters’ conceptions of appropriate employment niches for men versus women.  相似文献

Knowing when to compete and when to cooperate to maximize opportunities for equal access to activities and materials in groups is critical to children's social and cognitive development. The present study examined the individual (gender, social competence) and contextual factors (gender context) that may determine why some children are more successful than others. One hundred and fifty‐six children (M age=6.5 years) were divided into 39 groups of four and videotaped while engaged in a task that required them to cooperate in order to view cartoons. Children within all groups were unfamiliar to one another. Groups varied in gender composition (all girls, all boys, or mixed‐sex) and social competence (high vs. low). Group composition by gender interaction effects were found. Girls were most successful at gaining viewing time in same‐sex groups, and least successful in mixed‐sex groups. Conversely, boys were least successful in same‐sex groups and most successful in mixed‐sex groups. Similar results were also found at the group level of analysis; however, the way in which the resources were distributed differed as a function of group type. Same‐sex girl groups were inequitable but efficient whereas same‐sex boy groups were more equitable than mixed groups but inefficient compared to same‐sex girl groups. Social competence did not influence children's behavior. The findings from the present study highlight the effect of gender context on cooperation and competition and the relevance of adopting an unfamiliar peer paradigm when investigating children's social behavior.  相似文献

The process of agricultural restructuring embarked upon by the New Zealand government in the mid-1980s precipitated a period of financial hardship for many of the nation's farmers. It was not uncommon for families to adapt major adjustment strategies in order to maintain the viability of their enterprise at this time. Drawing upon a detailed case study of farm-level responses in a small rural locality, this paper argues that farm adjustments employed during and since this period have altered the character of family farming in the area in fundamental ways. Such change has been evident in the increasing heterogeneity of farm structure, and the alteration of farming goals and household labour arrangements, together with the evolution of local cultural norms. These transformations not only raise important questions about the future structure and sustainability of family farming in the area, but also inspire a conceptual reconsideration of the family farm unit as traditional linkages between the farm enterprise, household and property are weakened.  相似文献

This research responds to calls from within the field of urban ecology to explicitly incorporate humanities-based research in order to achieve robust interdisciplinarity. Our research provides an example of a place-based urban ecological analysis. We use this framework to analyze over a century of park planning and development within the city of Seattle. We identify four eras of park planning that are linked by a comprehensive 100-year park plan. This case study examines how the political, cultural, and economic aspects of park planning have produced and been influenced by long-term trends and historical contingencies. This research also offers practical insights for effective contemporary urban planning, emphasizing the need for flexible and adaptive long-term plans when confronted with unpredictable events, emerging political arrangements, changing cultural priorities, and shifting fiscal climates.  相似文献

Wildlife-human interactions are increasing in prevalence as urban sprawl continues to encroach into rural areas. Once considered to be unsuitable habitat for most wildlife species, urban/suburban areas now host an array of wildlife populations, many of which were previously restricted to rural or pristine habitats. The presence of some wildlife species in close proximity to dense human populations can create conflict, forcing resource managers to address issues relating to urban wildlife. However, evidence suggests that wildlife residing in urban areas may not exhibit the same life history traits as their rural counterparts because of adaptation to human-induced stresses. This creates difficulty for biologists or managers that must address problems associated with urban wildlife. Population control or mitigation efforts aimed at urban wildlife require detailed knowledge of the habits of wildlife populations in urban areas. This paper describes the history of wildlife in urban areas, provides examples of wildlife populations that have modified their behavior as an adaptation to urban stresses, and discusses the challenges that resource managers face when dealing with urban wildlife.  相似文献

Summary. The paper develops mixture models for spatially indexed data. We confine attention to the case of finite, typically irregular, patterns of points or regions with prescribed spatial relationships, and to problems where it is only the weights in the mixture that vary from one location to another. Our specific focus is on Poisson-distributed data, and applications in disease mapping. We work in a Bayesian framework, with the Poisson parameters drawn from gamma priors, and an unknown number of components. We propose two alternative models for spatially dependent weights, based on transformations of autoregressive Gaussian processes: in one (the logistic normal model), the mixture component labels are exchangeable; in the other (the grouped continuous model), they are ordered. Reversible jump Markov chain Monte Carlo algorithms for posterior inference are developed. Finally, the performances of both of these formulations are examined on synthetic data and real data on mortality from a rare disease.  相似文献

Family-responsive workplace arrangements, including schedule flexibility, reduced hours, and workplace social support, are often touted as important to employed parents' abilities to balance the simultaneous demands involved in work and childrearing. Empirical evidence regarding this supposition has most often focused on employed parents' perceptions of work-family incompatibility, leaving little understanding of (1) which arrangements are associated with parenting and children's well-being and (2) the process through which these arrangements may be related to these aspects of family life. A stress perspective on the work-family interface suggests that work-family arrangements might be related to parenting and children through the mechanisms of parents' psychological well-being. I use data from a regional sample of employed mothers to investigate this proposition. Findings from path models show that most relationships between arrangements and parenting are direct and unmediated by mothers' well-being and that work-family arrangements are only indirectly associated with children's socioemotional well-being.  相似文献

The article is based on six workplace case studies within a local economy and investigates the reasons behind the different utilization of part‐time workers within these workplaces. The research examines the content and nature of part‐time work in these organizations and the experiences of the part‐time workforce. The findings suggest that we need to distinguish between three types of part‐time workers; core, peak and ancillary. It is argued that such distinctions capture the variegated utilization of part‐time workers and contribute to the debate concerning the integration or marginalization of part‐time staff within workplaces. Furthermore, workplace cultures are an important arena for contextualizing these discussions. It is contended that the different uses of part‐time workers can be explained by different sectoral and organizational contexts but that the nature of part‐time work is also influenced by existing social relations within the workplace, notably with respect to gender, class and age.  相似文献

Previous research has shown that participation in voluntary associations, including those labeled nonpolitical, increases political participation. Using data gathered from 2,517 interviews for the American Citizen Participation Study, we complicate this understanding by exploring the relationship between voluntary association involvement and political activity in a more nuanced manner–separating association involvements according to the level of exposure to political dialogue and information, even within organizations typically considered apolitical. We find that the extent to which association involvement predicts political participation is dependent upon the level of political activity that transpires within these otherwise nonpolitical organizations. In order for participation in voluntary associations to lead to increases in political participation, participants must have exposure to political discourse. It is not the generic act of participation that supports political life but rather the opportunity to engage with politics that serves as an impetus for political activity. In light of this, we offer a critical exploration of existing federal tax policies governing nonprofit organizations.  相似文献
