Residential Instability,Family Support,and Parent–Child Relationships Among Ethnically Diverse Urban Families

From a social disorganization standpoint, neighborhood residential instability potentially brings negative consequences to parent–child relationship qualities, but family social support and racial/ethnic identity may modify this association. Using data (n = 3,116) from the Project on Human Development in Chicago Neighborhoods, this study examines associations between neighborhood residential instability and parent–child warmth and conflict, whether family social support moderates associations between residential instability and parent–child relationships, and variation by race/ethnicity. Multilevel models reveal that residential instability undermines parent–child relationship qualities, particularly for non‐White individuals. Family support is a protective factor for families in less stable neighborhoods and specifically buffers the association between neighborhood residential instability and reduced parent–child warmth. Among Hispanics, family support mitigates the association between residential instability and heightened parent–child conflict. Findings highlight residential instability as a detriment to parent–child relationships; families in unstable neighborhoods may benefit from family social support.     

Positive and Negative Aspects of Transracial Adoption: An Exploratory Study From Korean Transracial Adoptees' Perspectives

Participants, 92 Korean-born transracial international adoptees, responded to two open-ended questions designed to explore both positive and negative aspects of transracial adoption. Almost all of them reported experiencing both benefits and challenges, suggesting that transracial adoption is more complex than the polarized “success or failure” paradigm that underlies much of the transracial adoption research. Participants described negative features that are consistent with themes in the extant literature, including racism, alienation from their White families and peers, unfamiliarity with Korean culture, and identity confusion. They also described positive aspects that have been less frequently explored, such as greater learning and awareness and advantages of belonging to multiple cultures. Of interest, facets that some adoptees considered to be positive aspects of transracial adoption were considered by others to be negative aspects.     

Communicative Correlates of Satisfaction,Family Identity,and Group Salience in Multiracial/Ethnic Families

Guided by the Common Ingroup Identity Model ( S. L. Gaertner & J. F. Dovidio, 2000 ) and Communication Accommodation Theory ( C. Shepard, H. Giles, & B. A. LePoire, 2001 ), we examined the role of identity accommodation, supportive communication, and self‐disclosure in predicting relational satisfaction, shared family identity, and group salience in multiracial/ethnic families. Additionally, we analyzed the association between group salience and relational outcomes as well as the moderating roles of multiracial/ethnic identity and marital status. Individuals who have parents from different racial/ethnic groups were invited to complete questionnaires on their family experiences. Participants (N = 139) answered questions about relationships with mothers, fathers, and grandparents. The results of the multilevel modeling analyses are discussed in terms of implications for understanding multiracial/ethnic families and family functioning.     

中国地区失业率的邻居效应实证分析

本文通过空间权重法和空间虚拟变量法设计了中国地区失业率邻居效应变量,并将其加入地区失业率模型后使用1995～2007年中国省域数据进行实证研究。实证结果表明中国地区失业率邻居效应显著存在,这表明毗邻省份失业情况会明显影响本地区失业率水平,这意味着本省在进行就业政策制定时需考虑毗邻省份的实际情况,与此同时,毗邻省份间的充分沟通与合作应成为减少本省遭受外部失业冲击影响的可能措施。     

一种求解双目标flow shop排序问题的进化算法

提出一种求解双目标flow shop排序的递进多目标进化算法.算法采用改进的精英复制策略,在实现精英保留的前提下降低了计算复杂性;通过递进进化模式增加群体多样性,改善了算法收敛性;通过群体进化过程中对非劣解集进行竞争型可变邻域启发式搜索,增强了算法局部搜索性能.采用新算法和参照算法NSGA-II对31个标准双目标flow shop算例进行优化.研究结果表明,新算法在所有算例的求解中均获得了优于NSGA-II的非劣解集,验证了算法的有效性.     

Actor-Relational Planning in Deprived Areas: Challenges and Opportunities in Luchtbal Antwerpen,Belgium

In this article, we report and discuss our experience with actor-relational approaches (ARA) in the regeneration of a postwar housing estate in Luchtbal, Antwerp, Belgium. ARA are informed by post-structuralist ideas of space, complexity theory, and actor network theory. Although ARA itself is not new, the application of ARA to deprived area's such as Luchtbal is novel. We report how the approach has been elaborated, its process and outcome. We conclude with our evaluation from an insider's perspective.     

基于自适应大邻域搜索的鲁棒多项目调度方法

多项目资源管理有时需要采用一种资源专享-转移策略,该策略下可更新资源在多项目之间不共享,但在当前项目完工之后其资源可以转移至其它还未开始的项目。针对这一实际问题的理论研究非常有限。考虑活动工期的不确定性,从时差效用函数视角评价项目调度计划的鲁棒性,在考虑拖期成本-鲁棒性的多目标问题框架下,构建了一个资源专享-转移视角下的多项目资源分配(战术层)与鲁棒调度(运作层)双层决策优化模型。针对模型的NP-hard性质和多目标组合优化特征,设计了一种新的自适应大邻域搜索(adaptive large neighborhood search,ALNS)算法求解模型。该算法采用“项目-缓冲-资源-活动”列表的混合编码表示问题可行解,提出基于四类列表的destroy-repair邻域结构,设计一种超体积指标进行自适应搜索以提高算法性能。最后,为了验证ALNS算法的适用性和有效性,设计一种NSGA-II算法作为比较基准,通过大规模仿真实验对算法性能进行了对比分析,并探索工期不确定水平对多项目调度方案鲁棒性的影响。

Neighborhood Organizations and Resident Assistance to Police1

Police and scholars note that successful crime fighting requires police and residents to “co‐produce” public safety. However, residents are often reluctant to get involved in policing initiatives or even report crimes they witness. One possible means of stimulating resident involvement in crime‐control activities is through neighborhood organizations. This research, conducted on 1,313 residents of 42 neighborhoods in western South Carolina, investigates whether neighborhood organization participation increases the likelihood of assisting police in crime‐control efforts. Results indicate that organization participants are more likely to assist police than are nonparticipants, even after controlling for social cohesion, perceptions of police legitimacy, various policing strategies, fear of crime, and demographic factors.     

Step by step: tenant accounts of securing and maintaining quality housing with a housing choice voucher

Previous research on renters’ experiences in the Housing Choice Voucher (HCV) program is robust, but much of it has been conducted in the context of mobility interventions providing added resources. In contrast, this study focuses on HCV renters’ experiences searching for housing without the support of a mobility intervention. In semistructured interviews, 34 HCV renters describe their housing search processes and outcomes. We find that renters struggle to secure housing in their preferred neighborhoods due to limited information and financial costs such as application fees and security deposits. Discussion focuses on practice and policy reforms that might support greater housing choice.
