The Legalization of Abortion and Subsequent Youth Homicide: A Time Series Analysis

In this article, we examine the association between the legalization of abortion with the 1973 Roe v. Wade decision and youth homicide in the 1980s and 1990s. An interrupted time series design was used to examine the deaths of all U.S. 15- to 24-year-olds that were classified as homicides according to the International Classification of Diseases (codes E960-969) from 1970 to 1998. The legalization of abortion is associated over a decade later with a gradual reduction in the homicides of White and non-White young men. The effect on the homicides of young women is minimal. We conclude that the 1990s decline in the homicide of young men is statistically associated with the legalization of abortion. Findings are not consistent with several alternative explanations, such as changes in the crack cocaine drug market. It is almost inconceivable that in the United States of today, policies affecting the choice to have children would be justified as a means to control crime. Yet, if the legalization of abortion had this unintended effect, the full range of policy implications needs to be discussed.     

Domestic Violence and Substance Use: Tackling Complexity

Domestic violence and substance use are issues which pervadesocial work practice, yet are often on the margins of the knowledgebase for practitioners and their managers. This article providesan overview of the literature on substance use and domesticviolence, highlighting the problems with the separation of bothpractice and policy in these areas. Research on substance useand the needs of women survivors of domestic violence are explored,alongside the more substantial literature on perpetrators ofdomestic violence and patterns of substance use. The problemsof a simplistic analysis which suggest that there is a causallink between substance use and domestic violence are highlighted.Using data from an on-going research project, the sources ofthe continuing and dysfunctional separation of work in theseareas are explored.     

A Two-Dimensional Person-Environment Fit Analysis of the Performance, Effort and Satisfaction of Research Scientists

SUMMARY This study questions traditional assumptions in the person-environment fit models. Previous research has regarded any kind of fit as positive and any kind of misfit as negative. In the present study, this thinking is refined. It is proposed that consideration of the nature of the fit or misfit matters and that different dependent variables, including performance, may be affected differently. The proposal is tested with a sample of 212 research scientists. The findings demonstrate modest support for the differing effects of type of fit on the dependent variables.     

Music Education and minority groups cultural and musical identities in the ‘newer’ South Africa: white Afrikaners and Indians

Music Education, as well as cultural and musical identities are all being renegotiated, post‐Apartheid, within the so‐called ‘newer’ rather than the commonly known ‘new’ South Africa. The developing situation with certain minority groups is particularly interesting. Education in general has undergone much change since the first democratic elections in 1994: music education specifically has been affected by such change in terms of content, delivery and assessment. Within the South African context, cultural and musical identities are often intertwined with language, racial and even tribal identities, and discussing one implies the others. We are particularly interested here in the role of formal Music Education in relation to white Afrikaners and Indians as they renegotiate their cultural development, including musical aspects.     

Developmental Career Counseling with Teenage Parents

Although teenage parenthood is recognized by many counselors as a developmental identity crisis, it rarely has been viewed as a developmental career crisis. This article suggests developmental career assessment and counseling procedures for use with teenage parents.     

Maximization of reinforcement by two autistic students with accurate and inaccurate instructions

The present study examines maximization of reinforcement by two autistic individuals under conditions of no instructions, accurate instructions, and inaccurate instructions. Accuracy of instructions and magnitude of reinforcement for differential responding in a choice paradigm were systematically varied across phases. Subject one maximized reinforcement across all three conditions in seven experimental phases. Subject two maximized across these same seven phases, but also experienced three additional phases. In two of the additional phases, subject two maximized reinforcement. In a ninth phase, when reinforcement was intermittent rather than continuous, he failed to maximize reinforcement. Implications of the results for the controversies surrounding the concept of rule-governed behavior are discussed.
