本文基于上海市五个大型居住社区(以下简称"大居")的问卷调查与实地走访,梳理了上海"大居"现有就业机会、服务资源的配置情况以及居民需求状况。调查显示,上海"大居"在社区商业设施配套、公共交通设施、文体娱乐活动、物业管理服务以及教育资源等公共服务配套方面仍存在供需失衡问题,尚不能满足居民更高层次的需求。因而,要通过加快优质公共服务资源的导入,扭转"大居"弱势群体集聚的薄弱态势,推动人口结构优化,带动市场化资源的注入,培育"大居"社区内生增长动力,将"大居"建成多阶层、多群体共荣共享的高品质社区。  相似文献

International research collaboration (IRC) is associated with both positive and negative effects on the performance of research in emerging economies. While some authors claim that North–South collaborations improve scientific quality and visibility for Southern countries, others claim that it may entail the reorientation of research to comply with Northern agendas. South–South collaborations are thought to increase the focus on local affairs, therefore leading to a relatively small number of scientific international publications appearing in “high quality” journals. Research on the impact of IRC beyond publications in international journals has been neglected despite the importance of other products in knowledge creation. This research uses a broad range of scientific outputs to empirically assess such assumptions and explore the outcomes of IRC in Colombia. Results from multivariate regressions and nonparametric analyses show that, contrary to common assumptions, Colombian research teams collaborating with partners from the global South report higher scientific production, while those collaborating with Northern countries seem to contribute to local knowledge the most.  相似文献

本研究旨在考察社会资本、人力资本与物质资本及其交互变量对高校毕业生求职难度的影响。实证分析发现:社会资本、人力资本与物质资本对高校毕业生职业获得难度存在显著的影响。在搜寻成本模型中,社会资本同人力资本的交互项对高校毕业生在求职过程中的搜寻成本存在正向影响,即社会资本欠缺者,可以通过提升人力资本以降低搜寻成本;在求职结果模型中,社会资本同人力资本的交互项对高校毕业生的最终求职结果存在负向影响,即社会资本欠缺者,可以通过提升人力资本以提高求职成功的概率,从而降低求职难度。  相似文献

本文以同伴关系为切入点,考察社会结构异质性因素对流动儿童社会网络建构的影响。研究发现,流动儿童在同伴关系建构过程中表现出较高的主动性,交往对象呈现外向发展特征;流动儿童的兄妹数、成绩好坏、自身生活方式以及对城市居民态度的认知对其发展同伴关系的主动性有影响;流动儿童生活体验和生活环境对其发展同伴关系对象选择有影响。本文以实证研究回应了几种相悖的研究结论:布劳的肯定性结论与国内多数学者的否定性结论,系出自不同语境,各有合理性,但某些结论也需要进一步讨论。  相似文献

This study consists of a comparative analysis of patterns of de-escalation between ages 17–18 and 32, based on data from two well-known prospective longitudinal studies, the Cambridge Study in Delinquent Development (a study of 411 working-class males in London) and the Montreal Two Samples Longitudinal Study (a sample of 470 adjudicated French-Canadian males). Analyses focus on within-individual change, with individuals serving as their own controls. In this regard, the magnitude of measured change is relative to the past degree of involvement in offending. These results are contrasted with predictors of between-individual differences in offending behavior at age 32. We investigate the respective roles of cognitive predispositions and social bonds in the prediction of patterns of de-escalation, and assess whether it is possible to make relatively long-term predictions (over a 15-year period) about offending in adulthood. Findings suggest that traditional measures of social bonds and cognitive predispositions measured at age 17–18 are generally weak predictors of de-escalation up to age 32. However, these measures are stronger predictors of between-individual differences in offending gravity. These findings highlight the difficulties in making accurate long-term predictions about changes in individual offending patterns early in the criminal career.

Adolescent networks include parents, friends, and romantic partners, but research on the social learning mechanisms related to delinquency has not typically examined the characteristics of all three domains simultaneously. Analyses draw on data from the Toledo Adolescent Relationships Study (n = 957), and our analytic sample contains 51% male and 49% female as well as 69% white, 24% African-American, and 7% Latino respondents. Parents,’ peers,’ and partners’ deviance are each related to respondents’ delinquency, and affiliation with a greater number of deviant networks is associated with higher self-reported involvement. Analyses that consider enmeshment type indicate that those with both above average romantic partner and friend delinquency report especially high levels of self-reported involvement. In all comparisons, adolescents with deviant romantic partners are more delinquent than those youths with more prosocial partners, regardless of friends’ and parents’ behavior. Findings highlight the importance of capturing the adolescent’s entire network of affiliations, rather than viewing these in isolation, and suggest the need for additional research on romantic partner influences on delinquent behavior and other adolescent outcomes.

This study examined (a) the associations between school connectedness and early adolescent adjustment problems over a 1 year period and (b) the equivalence of these associations across gender. Five hundred middle school students (53.4% female), initially in the 6th and 7th grades, participated in the two-wave study. Results from two-group cross-lagged panel analyses were consistent across boys’ and girls’ data. After controlling for baseline levels of adjustment problems, school connectedness predicted lower levels of early adolescent conduct problems 1 year later. Regarding the opposite direction of associations, and even after baseline levels of school connectedness were taken into account, conduct problems predicted lower levels of subsequent school connectedness. There were no cross-lagged associations between depressive symptoms and school connectedness, although elevated levels of baseline depressive symptoms predicted higher levels of subsequent conduct problems. Findings elaborate previous research by demonstrating that early adolescents actively shape the middle school environment.

Sociometric nominations, social cognitive maps, and self-report questionnaires were completed in consecutive years by 327 students (56% girls) followed longitudinally from grade 7 to grade 8 to examine the stability of social standing in peer groups and correlates of changes in social standing. Social preference, perceived popularity, network centrality, and leadership were moderately stable from grade 7 to grade 8. Alcohol use and relational aggression in grade 7 predicted changes in social preference and centrality, respectively, between grade 7 and grade 8, but these effects were moderated by gender and ethnicity. Changes in social standing from grade 7 to grade 8 were unrelated to grade 8 physical aggression, relational aggression, and alcohol use after controlling for the grade 7 corollaries of these behaviors. Results are discussed in terms of their implications for understanding links between social standing and problem behaviors during adolescence.

This article aims to assess the role of important socio-economic factors in the family history of tuberculosis patients in Pakistan. Data were collected from 269 patients, and a logistic regression was used to determine the association between risk factors and the vicious circle of TB. Results of the logistic model show that significant risk factors associated with TB history in patients were education, household size, house structure, rooms in the home, room ventilation, monthly income, income food sufficiency, smoking, diabetes, and heart disease. The current TB control programme needs to formulate strategies to target specific risk factors and poverty reduction simultaneously to break the vicious circle of tuberculosis.  相似文献

Access to reproductive health services and products in remote and rural communities is a critical area of concern for developing countries. This article considers a pilot intervention in three districts of Pakistan where “Business-in-a-Box” as a model of place-based social innovation is used to improve the socio-economic conditions of women in remote rural settings through socially responsible micro-franchising. It finds that such programmes help build a sense of community, ownership and grassroots capabilities and skills. The article also discusses the impacts of such actions on the individual and community life, and the need to upscale and sustain these initiatives.  相似文献
