Employment gains and wage declines: The erosion of black women’s relative wages since 1980

Public policy initiatives in the 1950s and 1960s, including Affirmative Action and Equal Employment Opportunity law, helped mitigate explicit discrimination in pay, and the expansion of higher education and training programs have advanced the employment fortunes of many American women. By the early 1980s, some scholars proclaimed near equity in pay between black and white women, particularly among young and highly skilled workers. More recent policy initiatives and labor market conditions have been arguably less progressive for black women’s employment and earnings: through the 1980s, 1990s, and the first half of the 2000s, the wage gap between black and white women widened considerably. Using data from the Current Population Survey Merged Outgoing Rotation Group (CPS-MORG), this article documents the racial wage gap among women in the United States from 1979 to 2005. We investigate how demographic and labor market conditions influence employment and wage inequality among black and white women over the period. Although shifts in labor supply influence the magnitude of the black-white wage gap among women, structural disadvantages faced by black women help explain the growth in the racial wage gap.     

Shopping Model of the Time-Sensitive Consumer

The shopping behavior of time-sensitive consumers has been modeled as an economic model of choice. Consumers are said to balance the costs of time spent commuting to the store and in the store with storage costs and other nontime costs of shopping. In so doing, these consumers tend to minimize their overall costs. Propositions are developed and tested using this economic model of shopping. The model is extended beyond time sensitivity to include deal proneness; further propositions are developed and tested using the extended model. The empirical results support the derived models.     

Alleviating poverty or reinforcing inequality? Interpreting micro‐finance in practice,with illustrations from rural China

Academic and political discussions about micro‐finance have been found lacking in predictive power, because they are based on orthodox economic theory, which does not properly comprehend the social components of credit. I take a better approach, utilizing credit theory – specifically, Ingham's explication of how the nature of money as credit leads to social inequality. I also expound the perspective that morality is not separate from considerations borrowers make in micro‐finance programmes on the micro level. I draw upon illustrations from my fieldwork in rural China, where a group‐lending micro‐finance programme was administered as part of a larger government‐initiated effort across the country.     

Integrating Couple Teamwork Conversations Into Child Welfare Practice

This article summarizes the importance of and challenges to addressing couple teamwork issues in the child welfare population. Although there is substantial evidence to support the importance of healthy adult relationships for child well-being and the prevention of child maltreatment, there are a number of barriers to addressing these couple relationships in child welfare. These barriers include diverse family configurations and uncertain relationship commitments, the individual presentation of maltreatment, and worker discomfort with these issues. Additionally, there are few relationship programs designed specifically for low income individuals, and a number of policy and environmental constraints affect couple relationships in this population. However, building upon a comprehensive practice model for child welfare known as Solution Based Casework, this article describes casework skills to initiate and maintain couple teamwork conversations. These initiation skills include assessing patterns in everyday life, building partnerships with families, normalizing and externalizing problems, and tracking interactional sequences related to parent teamwork. The maintenance skills described include maintaining a common language, utilizing family team meetings, recognizing small steps of change, keeping treatment providers on track, and making the most of setbacks. These practical guidelines will assist child welfare professionals with building couple teamwork for child protection.     

An Evaluation of Healthy Relationship Education to Reduce Intimate Partner Violence

This research evaluated the impact of the Within My Reach healthy relationship education program on intimate partner violence for 419 high-risk adults in an urban area. Key outcomes such as relationship knowledge, communication/conflict resolution skills, relationship quality, and physical and emotional abuse were evaluated through survey research immediately post- and 6-months postprogram participation. Results suggest that participation in the Within My Reach program is associated with a statistically significant decrease in physical and emotional abuse, as well as isolation behaviors. Differences by participant demographics and the role of communication skills and relationship quality as mediators of these outcomes are also discussed.     

Developmental Precursors of Number of Sexual Partners From Ages 16 to 22

This study examines family and child characteristics, parent and peer relationships, and early adolescent behavior as statistical predictors of trajectories of number of sexual partners from midadolescence through early adulthood using data from 527 participants in the Child Development Project. Early adolescent developmental antecedents accounted for modest variance in number of sexual partners. Latent growth models revealed that African American race, more advanced pubertal development, lower parental monitoring knowledge, association with more deviant peers, and lower grade point average in early adolescence each predicted having more sexual partners at age 16. In addition, non‐African American race, lower child IQ, higher parental monitoring knowledge, and lower early adolescent internalizing problems each was associated with a higher rate of growth in number of sexual partners over time at the ages following 16. Latent growth mixture modeling identified subgroups with distinct trajectories of involvement with sexual partners that were associated with family and child characteristics, parent and peer relationships, and behavior in early adolescence.     

Code–convergent borrowing in Louisiana French

The nature of lexical and structural borrowing has been at the forefront of sociolinguistic debates for many years. This study analyzes bilingual lexemes and morphemes of English–origin loanwords from a Louisiana corpus of twenty–two French/English speakers. French Louisiana, however, has been undergoing language shift from French to English for three generations and, as a consequence, language dominance is in a parallel state of shift. This competing dominance produces borrowings characterized by a range of phonological integration coupled with bound morphemes from both languages. These data suggest that examining borrowing beyond the word level reveals a highly complex interplay of often competing and overlapping grammars.     

Min-energy voltage allocation for tree-structured tasks

We study job scheduling on processors capable of running at variable voltage/speed to minimize energy consumption. Each job in a problem instance is specified by its arrival time and deadline, together with required number of CPU cycles. It is known that the minimum energy schedule for n jobs can be computed in O(n³) time, assuming a convex energy function. We investigate more efficient algorithms for computing the optimal schedule when the job sets have certain special structures. When the time intervals are structured as trees, the minimum energy schedule is shown to have a succinct characterization and is computable in time O(P) where P is the tree’s total path length. We also study an on-line average-rate heuristics AVR and prove that its energy consumption achieves a small constant competitive ratio for nested job sets and for job sets with limited overlap. Some simulation results are also given.
