人才是促进城市社会经济转型发展的重要因素。在文献分析的基础上,以杭州市为实证,应用核密度分析法对2000年、2010年、2016年杭州市的人才规模和空间格局进行计算分析。结果显示:杭州市的人才规模具有"先快后慢"的增长趋缓特征;人才分布格局具有从"单中心结构"向"多中心结构"演化的趋势;城市中心区是各年龄阶段人才的高度集聚区域,同时城市外围空间已成为人才规模增长与空间集聚的主要区域。进一步判断:城市地理空间对人才集聚格局具有重要的影响作用;城市重要的研究型大学、创新型企业和政策措施等对人才集聚起到明显的促进作用并使城市外围的人才分布表现出显著的空间分异特征。在此基础上,对促进城市人才规模增长、优化人才分布格局以及创新发展提出相应的空间对策建议。  相似文献

空间集聚存在不同的尺度,城市区域作为当今具有较强竞争力的区域空间组织是一种大尺度的集聚。经典集聚理论、模型以及相关扩展性实证研究为城市区域尺度集聚的形成提供了方向性的暗示。这种集聚在本质上是聚集力和分散力动态组合的一种空间结果,其中,分散力的增强对城市区域尺度集聚的形成起到了重要的作用。随着区际运输成本的降低,核心区域-外围区域间共享的区际外部性逐渐增强;核心区域的拥挤效应进一步加强了经济活动向外围转移的倾向,最终促使部分经济活动突破地区边界,在地理邻近的地域之间形成更强的空间依赖,呈现出大尺度的经济集聚。城市区域尺度集聚的经济性为发展城市群、促进区域一体化提供了理论依据,但在实践中也遇到很多障碍,这对政府在打破行政割据、促进要素自由流动以及加强中心城市周边地区发展方面提出了要求。  相似文献

一、城市副中心的形成与内涵 在城市发展过程中,要素的集聚和扩散两种作用互为消长,不断塑造着城市的地域形态.18世纪中叶工业革命后,城市的区位交通优势吸引周边的资本、人口等要素和经济活动不断向城市集中,城市规模在这一时期得到迅速的膨胀.到了20世纪初,随着电话、电车等的普及,城市中的要素集聚过程加快,城市中心区由于具有最优越的区位优势和交通可达性,逐渐成为城市商业、商务等功能的中心.1 923年,美国城市社会学家伯吉斯在其创立的"同心圆模式"中首次提出了CBD(中央商务区)的概念,认为城市中心是商业零售业和服务业会聚之处.随着经济的发展,CBD的职能进一步扩展,涵盖了金融保险、贸易、信息咨询、会展、公寓及配套的商业文化、市政、交通服务设施等多种职能和活动.如果说CBD的产生主要是经济要素追求规模经济,不断向城市中心集聚的结果,那么城市副中心则是在城市中心出现规模不经济,CBD功能向外扩散过程中产生的位于城市边缘区的新的城市功能集聚点.  相似文献

The study examined whether differences in gender and family status affect parental caregiving disposition and acceptance of children among parents of children in mid-childhood. The number of participants were 122 divorced-custodial fathers, 107 married fathers, 85 divorced-custodial mothers, and 82 married mothers (n?=?398). A comparison among four groups of parents revealed the following gender differences: mothers scored higher on anxious caregiving and parental acceptance than fathers, and lower on avoidant caregiving. Regression analysis indicated that the higher the caregiving avoidance or anxiety, the lower the parental acceptance. Family status moderated parental acceptance, as avoidant caregiving was associated with reduced parental acceptance among married parents, but not among divorced custodial parents. The finding that avoidant caregiving was not associated with reduced acceptance among divorced custodial parents implies that their parental acceptance behaviors toward their children are affected by their parental status as sole custodial parent, and the associated responsibilities, rather than by gender.  相似文献

Background: As conventional cigarette use is declining, electronic cigarette (“e-cigarette”) use is rising and is especially high among college students. Few studies examine dual use of e-cigarettes and cigarettes among this population. This study explores the relationship between dual and exclusive e-cigarette / cigarette use and perceptions of harm and addictiveness of both products. Methods: This is a cross-sectional analysis of data from students attending 24 colleges in Texas (n=5,482). Multinomial logistic regression was employed to test the association between current e-cigarette / cigarette use and perceived harm and addictiveness of both products. Three tobacco groups were included: cigarette only users, e-cigarette only users, and dual users. Results: Dual users reported lower perceived harm of e-cigarettes most consistently (p<0.001, all comparisons). Perceived harm of cigarettes was significantly lower among cigarette only and dual users only, compared to non-users (p<0.001, all comparisons). Compared to non-users, all three groups reported significantly lower perceived addictiveness of e-cigarettes (p<0.001, all comparisons). The same finding was observed for perceived addictiveness of cigarettes, though findings were less consistent for the e-cigarette only group (p<0.02, all comparisons except one). Conclusion: Findings demonstrate that among college students, perceptions of harm and addictiveness of e-cigarettes are lower than those for conventional cigarettes. For both products, perceptions of harm and addictiveness were lower among exclusive and dual users, compared to non-users.  相似文献

This study investigated different types of friendships and the behavioral profiles of different types of friends in relation to individual adjustment. In 102 classes with preadolescents (mean age 11), 737 independent friendship dyads, and in 149 classes with adolescents (mean age 14), 1,102 friendship dyads were identified. At each age group, cluster analyses on the behavioral profiles of the dyads yielded three friendship types, with two types of friends within each friendship type: Socially Withdrawn friendship (Victimized Withdrawn and Prosocial Withdrawn friends), Prosocial friendship (High Prosocial and Less Prosocial friends), and Antisocial friendship (Bullying Antisocial and Antisocial friends). The behavioral profiles of the two friends in Prosocial friendships were marked by similarity and in the other two types by complementarity. Both Victimized Withdrawn and Bullying Antisocial friends were less adjusted than participants without friends while Prosocial friends were more adjusted.  相似文献

ABSTRACT

This article is a qualitative study which addresses the interacting relationship between the environmental context of care giving and abuse and neglect of older adults. These are examined through a thematic content analysis of risk factors identified in sixteen ‘in depth’ interviews of abused and neglected victims including two of their abusers. The interviews provide a portrait of their past and present situations, their roles and relationships and the process through which the interviewees move into their described process of powerlessness.

The interviewees are analysed through a critical, systemic, ecological analysis of the historical, gender and cultural perspectives of the interviewees. Through the relationships of the victims and their abusers in the macro, meso, exo and micro systems, questions are raised about the growing debate regarding changes in family patterns and demographics that affect how societies define the provision of care to their dependent adults. They demonstrate that violence is produced by complex interacting systems and significant events, that impact on the life courses of some older adults and some care givers leading them into powerless positions and resulting in abuse and neglect.  相似文献

ABSTRACT

Historically, federal and state legislation placed different conditions on same- and opposite-sex couples' ability to marry, adopt, or exercise their parental rights. Given the historical intertwining of marriage and parenting, legal issues remain hinged on differing conceptions of marriage and what constitutes a legal family in the United States, especially for same-sex partners compared to their different-sexed couple counterparts. This article provides a historical review of decisions that serve as the foundation for queer parenting rights in the United States. A key focus is on the impact of the U.S. Supreme Court Obergefell v. Hodges (2015) marriage decision on queer parenting and its relevance to researchers and practitioners whose work involves queer families. State discrepancies continue to exist for the treatment of parental rights in spite of the legalization of same-sex marriage. Finally, suggestions are provided for future directions for the field.  相似文献

We extended on previous work by examining the contextual nature of parenting goals in mothers and fathers of adolescents. We also examined dyadic parenting similarity in parenting responses and parenting goals. Participants were 285 primarily professional (48.6%), White (82.7%) parents of adolescents aged 14 to 17 years old (mothers n = 213, fathers n = 68, dyads n = 43). Results of a 2 × 2 × 6 MANCOVA indicated that parenting goals were influenced by characteristics of the situation but not by parent or adolescent gender. There was dyadic parenting similarity for parenting responses and dyadic similarity for parenting goals. The implications of these findings for parenting interventions and future parenting research using within family comparisons are discussed.  相似文献
