Remittances and labour market outcomes: Evidence from Mexico

The effects of remittances on labour market outcomes have been studied by many researchers, primarily using micro‐level data. While a few studies have also used macro‐level data, they suffer from endogeneity bias due to the inclusion of remittances in their estimations. The present study attempts to fill the gap in the literature by using a set of panel data of Mexican states and by addressing the endogeneity bias with a system GMM (generalized method of moments) estimator. The main conclusions are that remittances increase labour force participation rates and reduce median hours worked, critical employment and unemployment duration.     

Elevating financial capability in child welfare services: Early efforts in the Grand Challenge

The great majority of families involved in the child welfare system are economically vulnerable, have limited incomes, and face a high risk of financial exploitation. Limited opportunities to participate meaningfully in the financial sector, along with poor decision making, can lead to overwhelming debt, eviction, and poverty that compromise child safety and wellbeing and can cripple efforts to reunify families. This article discusses the need to elevate financial capability–which scholars and practitioners define as knowledge of financial matters and means to exercise that knowledge. It addresses nascent research examining financial capability and asset building, the expanding role of the topic in human services, and efforts in Missouri to integrate an understanding of financial capability in work with families involved in the child welfare system. Such integration holds the promise of fulfilling the safety, permanence, and wellbeing goals of the child welfare system; involving a wider set of community partners; and achieving the federally mandated ‘normalcy’ in foster care.     

The Measurement of Intellectual Influence

This paper examines the problem of measuring intellectual influence based on data on citations between scholarly publications. We follow an axiomatic approach and find that the properties of invariance to reference intensity, weak homogeneity, weak consistency, and invariance to splitting of journals characterize a unique ranking method. This method is different from those regularly used in economics and other social sciences.     

Building stronger weak ties among a diverse pool of emergent nonprofit leaders of color

This article explores theoretical underpinnings of social capital and strong and weak ties as they relate to relationships within, between, and among six cohorts of promising nonprofit leaders of color in a northwestern U.S. city. Using mixed methods, including network analyses, it considers the impact and potential of a university‐community collaboration to deliver a program to promising emergent leaders nominated for their talent and commitment to the work of their community‐based organizations, often in competition for limited resources. The article considers the program's implicit effect on relationships and reveals intersector connections among alumni. Findings show substantial alumni movement among organizations, increasing the potential for collaboration and mentoring relationships. We conclude with recommendations for programs seeking long‐term impact and discuss a series of unanticipated findings and the questions they engender, many critical as communities and organizations become more diverse and social needs do not diminish.     

Capping Kids: The Family Cap and Nonmarital Childbearing

An explicit goal of policymakers in drafting welfare reform policies was to reduce incentives for nonmarital childbearing. This paper estimates the extent to which state welfare reforms have lowered age and race-specific nonmarital fertility. Using state-level data from 1984 to 1999—a time period that includes the passage and implementation of national welfare reform—we estimate fixed effects models corrected for heteroscedasticity and autocorrelation. We find evidence that the family cap, a policy that decreases or eliminates the incremental increase in benefits for mothers who have an additional child while on welfare, is associated with a decline in nonmarital birth ratios. However, we also find that the family cap is associated with higher marital birth rates. Taken together with other research, our findings suggest evidence of policy endogeneity.

Real men, real husbands: Caregiving and masculinities in later life

Drawing on data from in-depth personal interviews with a sample of fifty-three older men caring for their impaired wives, authors report findings on these men's caregiving experience, specifically on the way they see themselves as men within such role. Through analytic methods based upon content analysis and open coding, authors found that when describing their gendered understanding of themselves participants evidenced several negotiations with the dominant masculine ideology in order to maintain their sense of masculinity and legitimate their presence in a feminine role. This was accomplished by reframing their definition of a man and reinforcing that of a husband and by retaining varying degrees of power over the caregiving relationship. The social visibility of the role within particular gendered community-based social networks was found to be important in shaping these older men's masculinities.     

The relationship between sexual abuse and drug use: findings from Houston's Safer Choices 2 program

Self-report drug use data were collected from 282 female alternative school students surveyed through the Safer Choices 2 study in Houston, Texas. Data collection took place between October 2000 and March 2001 via audio-enabled laptop computers equipped with headphones. Logistic regression analyses indicated that sexual abuse history was significantly associated with lifetime use (OR = 1.9, p < or = 0.05). While the relationships tested in this study are exploratory, they provide evidence for an important connection between sexual abuse and substance use among female alternative school students.     

Solving Steiner Tree Problems in Graphs with Lagrangian Relaxation

This paper presents an algorithm to obtain near optimal solutions for the Steiner tree problem in graphs. It is based on a Lagrangian relaxation of a multi-commodity flow formulation of the problem. An extension of the subgradient algorithm, the volume algorithm, has been used to obtain lower bounds and to estimate primal solutions. It was possible to solve several difficult instances from the literature to proven optimality without branching. Computational results are reported for problems drawn from the SteinLib library.
