The consequences of respondent attrition in panel studies: A simulation based on the Rochester youth development study

Subject attrition is a potentially serious threat to the validity of inferences drawn from panel studies of delinquency and drug use. Prior assessments of this issue produce somewhat conflicting results, with some finding that respondents who leave the panel have higher rates of delinquency and drug use than those who remain, while other studies report little or no differential attrition. Despite these findings, there has been virtually no examination of the extent to which respondent attrition can bias substantive findings in panel studies of delinquency and drug use. The present article addresses this issue by simulating higher levels of attrition in an ongoing panel study that has a low rate of attrition and little differential attrition. It finds that failure to include more elusive respondents (those who are more mobile) would bias estimates of prevalence and frequency of delinquency and drug use as well as results from basic regression analyses. Failure to include less cooperative respondents (those who require more contacts) produces similar, but somewhat smaller, differences. The methodological implications of the results are discussed.     

Intergenerational continuities and discontinuities in intimate partner violence: a two-generational prospective study

This study focuses on intergenerational continuity in violent partner relationships. We investigate whether exposure to caregiver intimate partner violence (IPV) during adolescence leads to increased involvement in IPV during early adulthood (age 21-23) and adulthood (age 29-31). We also investigate whether this relationship differs by gender. Although there is theoretical and empirical support for intergenerational continuity of relationship violence, there are few prospective studies of this issue. We use data from the Rochester Youth Development Study (RYDS), a longitudinal study of the development of antisocial behavior in a community sample of 1,000 urban youth followed from age 14 to adulthood. The original sample includes 73% men and 85% African American or Hispanic youth. Measures come from a combination of interviews and official records. The Conflict Tactics Scale (CTS) is used to assess IPV and severe IPV in the youth and parent generations. Analyses controlled for child physical abuse, race/ethnicity as well as parent education, family stability, and poverty. In multivariate models, adolescent exposure to caregiver severe IPV resulted in significantly increased risk of relationship violence in early adulthood (age 21-23). Furthermore, there is an indirect effect of adolescent exposure to severe IPV on later adult involvement in IPV (age 29-31), mediated by involvement in a violent relationship in early adulthood. These results were largely invariant by gender. However, we observed a direct pathway between IPV exposure and adult IPV for women (marginally significant) suggesting that adolescent exposure to caregiver IPV may set in motion women-specific processes.     

Temporal Linkages in Violent and Nonviolent Criminal Activity

Research on the temporal distribution of criminal behavior has highlighted two distinct mechanisms—population heterogeneity and state dependence. Most of this work indicates that long-term patterns of criminal offending reflect a mixture of stable individual differences and the causal effect of life events and experiences. Yet several ambiguities remain. Among the most important of these problems is whether both population heterogeneity and state dependence processes operate for different types of offending. We use longitudinal official record and self-report data for violent and non-violent offending activity from the Rochester Youth Development Study to address these ambiguities.     

The measurement of family process variables: The effect of adolescent and parent perceptions of family life on delinquent behavior

Both adolescent and parental perceptions of how family members interact with and feel about one another are examined to determine their relationship to official and self-reported delinquent behavior. Consistent with prior research, adolescent perceptions of family processes were weakly related to those of their parents. Both parental and adolescent family process measures made independent and significant contributions to the explanation of self-reported and official delinquent behavior. Parental measures contributed more to the explanation of official data than did adolescent measures when compared to the results for self-reported delinquency. Methodological and substantive reasons for these findings are discussed. The importance of taking into account parental perceptions of family interaction, as well as the perceptions of adolescents, is emphasized.     

On the structure of business incubators: de-coupling issues and the mis-alignment of managerial incentives

Business incubators are structurally complex and have resisted any major change to their internal structure, replicating throughout the world in large numbers, and delivering value through numerous models. A question, thus arises, what specific structural properties of incubators facilitate the organizational form’s replication and performance in a range of institutional contexts? In order to shed light on this question, an exploratory-inductive approach is adopted; and, utilizing the tools of organization theory, the internal environment of the business incubator is de-coded. This draws attention to attributes of the hybrid incubator-form’s internal structural properties that have not been discussed in the past, including de-coupling issues and the mis-alignment of managerial incentives with the actual role of incubating. These properties, rather than impacting incubators’ status, award incubators with ceremonial value and help their managements avoid close inspections of performance. This in turn, it is proposed, has allowed for their rapid replication in a variety of socio- cultural, economic and institutional contexts.     

Prison labor and recidivism

This study examines recidivism among inmates who participated in prison industry programs during confinement and a comparison group of inmates who were not employed in prison industry. Industry participants had lower recidivism rates than nonparticipants, but when differences between the groups on other characteristics associated with recidivism were controlled, the recidivism rates of participants and nonparticipants were virtually identical. A proportional hazards regression model was estimated that showed that, net of other variables, the effect of prison industry participation on the probability of postrelease felony arrest was small and insignificant. The findings are discussed in the context of existing correctional outcome research and recent developments in prison work programs.
