RESIDENTIAL MOBILITY AND ATTEMPTED SUICIDE AMONG ADOLESCENTS: An Individual-Level Analysis

Building on the Durkheimian legacy's emphasis on social integration as a determinant of suicidal behavior, many macrolevel studies have observed an association between aggregate rates of geographical mobility and suicide, but little research has explored this connection at the individual level. We use data from 9,594 respondents who participated in two waves of the National Longitudinal Study of Adolescent Health to examine the effect of recent residential mobility on attempted suicide one year later and to explore the mechanisms that potentially transmit this effect. We find that among adolescent girls, recent movers are about 60 percent more likely than nonmovers to report having attempted suicide during the following year and that this difference cannot be readily explained by mover versus nonmover differences in preexisting demographic and family background characteristics. Some of the apparent effect of residential mobility on females' risk of attempting suicide operates through higher rates of victimization and delinquency, lower levels of school attachment, higher rates of social isolation, and a tendency for movers to associate with peers who exhibit delinquent behaviors and who themselves have attempted suicide. In contrast, we find no evidence that mobile female adolescents' deficit of parental social capital or lower levels of school engagement can account for the difference in attempted suicide risk between movers and nonmovers. We also find that residential mobility is not significantly associated with suicide attempts among adolescent males.     

Large firms,legitimation and industry identity: The growth of the North Carolina wine industry

This paper examines the recent rapid growth of wineries in North Carolina and the role that a few large wineries have played in establishing efficiency parameters for small wineries. Specifically, we argue capital intensive wineries have subsidized institutional changes and promoted operational procedures that have improved quality and reputation of the embryonic industry. In establishing efficiency mandates they have helped incipient industry identity and also provided an important benchmark for industry newcomers, thus facilitating further entrepreneurial growth.     

A capture-recapture survival analysis model for radio-tagged animals

In recent years, survival analysis of radio-tagged animals has developed using methods based on the Kaplan-Meier method used in medical and engineering applications (Pollock et al. , 1989a,b). An important assumption of this approach is that all tagged animals with a functioning radio can be relocated at each sampling time with probability 1. This assumption may not always be reasonable in practice. In this paper, we show how a general capture-recapture model can be derived which allows for some probability (less than one) for animals to be relocated. This model is not simply a Jolly-Seber model because it is possible to relocate both dead and live animals, unlike when traditional tagging is used. The model can also be viewed as a generalization of the Kaplan-Meier procedure, thus linking the Jolly-Seber and Kaplan-Meier approaches to survival estimation. We present maximum likelihood estimators and discuss testing between submodels. We also discuss model assumptions and their validity in practice. An example is presented based on canvasback data collected by G. M. Haramis of Patuxent Wildlife Research Center, Laurel, Maryland, USA.     

Predisposition to seek mental health care among Black males transitioning from foster care

This study examined the predisposition to seek mental health care in the future for personal and mental health problems among Black males transitioning from the foster care system (n=74). Results of simultaneous multiple regression analysis showed that custody status, diagnosis of a DSM-IV psychiatric disorder, and emotional control contributed significantly to the prediction of Black male's predisposition to seek mental health care. Specifically, Black males who were still in foster care were more predisposed to seek mental health care, whereas those diagnosed with a DSM-IV psychiatric disorder and who adhered more to the norm of emotional control were less predisposed to seek mental health care. Implications for mental health service delivery are discussed.
