Impact of Community on Personal Well-Being in Urban China

ABSTRACT

As the work-unit system fell after economic reform in China, neighborhoods replaced work units as the primary provider of vital social services for the urban population and became a new social space for enhancing the quality of people's well-being. This study examined the neighborhood characteristics that influenced personal well-being of residents. Drawn by multistage sampling and administered by face-to-face interviews, the survey included a sample of 976 participants from 31 neighborhoods in urban Shanghai. Results indicate that neighboring behaviors enhanced subjective well-being of the young and middle-aged residents but had no impact on older people. Sense of community, on the other hand, was found to contribute to well-being of all age groups and was particularly strong among older people in more deprived neighborhoods. Findings inform development of community practice strategies for vitalizing community efficacy and fostering individual well-being in urban China. Recommendations for future research are made using the results of this study.     

Greedy algorithms for the profit-aware social team formation problem

Motivated by applications in online labor markets, we study the problem of forming multiple teams of experts in a social network to accomplish multiple tasks that require different combinations of skills. Our goal is to maximize the total profit of tasks that are completed by these teams subject to the capacity constraints of the experts. We study both the offline and online settings of the problem. For the offline problem, we present a simple and practical algorithm that improves upon previous results in many situations. For the online problem, we design competitive deterministic and randomized online algorithms. These are complemented by some hardness results in both settings.

     

Income Inequality and Opioid Prescribing Rates: Exploring Rural/Urban Differences in Pathways via Residential Stability and Social Isolation

While opioid prescribing rates have drawn researchers' attention, little is known about the mechanisms through which income inequality affects opioid prescribing rates and even less focuses on whether there is a rural/urban difference in mediating pathways. Applying mediation analysis techniques to a unique ZIP code level dataset from several sources maintained by the Centers for Medicare and Medicaid Services, we explicitly examine two mechanisms through residential stability and social isolation by rural/urban status and find that (1) income inequality is not directly related to opioid prescribing rates, but it exerts its influence on opioid prescribing via poor residential stability and elevated social isolation; (2) social isolation accounts for two‐thirds of the mediating effect of income inequality on opioid prescribing rates among urban ZIP codes, but the proportion halves among rural ZIP codes; (3) residential stability plays a larger role in understanding how income inequality matters in rural than in urban ZIP codes; and (4) beneficiary characteristics only matter in urban ZIP codes. These findings offer nuanced insight into how income inequality affects opioid prescribing rates and suggests that the determinants of opioid prescribing rates vary by rural/urban status. Future research may benefit from identifying place‐specific factors for opioid prescribing rates.     

An Unfinished Reflexive Journey: Social Work Students' Reflection on their Placement Experiences

The fieldwork placement is recognized as one of the major componentsof social work education and a major determinant of its quality.A key aspect of the learning process in the fieldwork placementis the exposition of practice encounters to the students’critical reflection. Given the importance of the process of‘reflection’ or ‘reflective learning’,a qualitative study based on the reflective logs of social workstudents was conducted to explore the meaning of social workfield education and the learning experiences of social workstudents during their placement. The study findings revealedthat disturbing events experienced by students in their fieldworkwere a catalyst to their reflective process. Meanwhile, theirundue concern with knowledge and skills application within acircumscribed knowledge frame suggests the dominant influenceof scientism and competence-based practice in social work, inwhich learning outcomes and instrumental and technical reasoningare highly emphasized. Discovery of ‘self’ was alsothe major premise in the students’ reflection logs, inwhich a majority of them took their prevailing self-identityas a constant state to be verified in interaction with othersin the fieldwork placement. Reflexivity is manifested in askingfundamental questions about assumptions generated by formaland practice theories; it addresses the multiple interrelationsbetween power and knowledge, and acknowledges the inclusionof self in the process of knowledge creation in social workpractice. Its realization in social work education requiresthe social work educators’ reflexive examination of thedynamics that influence the construction of curriculum, whichin turn construct our prospective social workers.     

A Proportional Random Utility Approach to Qualitative Response Models

A new functional form of the response probability for a qualitative response model is proposed. The new model is flexible enough to avoid the constraint of independence from irrelevant alternatives, which is perceived as a weakness of the multinomial logit model in some applications. It is computationally simpler than the multinomial probit model and is promising for analyzing problems with a moderate number of alternatives.
