Recidivism and resilience in juvenile sexual offenders: an analysis of the literature

The majority of research that exists studying juvenile sex offenders (JSOs) is dominated by the predilection that identifying risk factors associated with recidivism will benefit both the JSOs and treatment providers. Further, the majority of existing treatments are guided by research that has identified what makes JSOs more likely to reoffend. Absent from the majority of the literature is an examination of the strengths and positive characteristics demonstrated by JSOs that may prove useful in both reducing recidivism and increasing the likelihood of achieving positive outcomes (i.e., demonstrating resilience). Research examining known risk factors for sexual and nonsexual recidivism is described. Next, literature on resilience is reviewed, followed by a discussion of this literature in the context of treatment for JSOs. Finally, future directions of research are presented.

Joint Reviews: The Methodology in Action

Correspondence to Jill Humphrey Family, Adoption and Family Finding Unit, 3 Unthank Road, Nowich NR2 2PA, UK. E-mail: jill.humphrey.socs{at}norfolk.gov.uk Summary Joint Reviews form the crown of the regulatory apparatus insocial services in England and Wales, and reviewers have craftedan impressive methodology to investigate the workings of socialservices authorities. My aim in this article is to expose andexplore the social processes underpinning this methodology,drawing upon interviews with people on both sides of the regulatoryfence and an ethnographic study of Joint Reviews in action.I shall discuss the cultural politics of regulatory researchand demonstrate the ways in which communications and interpretationsin the field can be constructed, confused, and contested. Thisis not an argument against regulation but rather a quest forgreater reflexivity in regulation and research.     

CULTURAL AND ECONOMIC SOURCES OF HOMICIDE IN THE UNITED STATES

Are high rates of homicide better explained by cultural or economic factors? Some research suggests that a regional culture of violence underlies high rates of homicide, whereas other research suggests that poverty or economic inequality increases the likelihood of homicide. A major limitation of this body of research has been the failure of researchers to include an indicator of cultural support for violence that is analytically separate from measures of southern region. In this article, a 12-item Legitimate Violence Index (LVX) is introduced that measures cultural support for violence. Using the 50 states as the units of analysis, hypotheses derived from cultural and economic theories of homicide are investigated using multiple regression. Several additional variables are included in the analysis to control for spurious relationships. The results show that legitimate violence, poverty, and economic inequality are significantly associated with state-to-state differences in the incidence of homicide.     

ESTIMATION OF THE CONDITIONAL PROBABILITY OF TUBERCULOSIS GIVEN THE RESPONSE OF A MANTOUX TEST

For the planning of community tuberculosis, prophylaxis one must know the prevalence of tuberculosis (TB) infection as a function of response to the Mantoux intradermal tuberculin test; the standard test for indicating Mycobacterium TB infection. The skin induration size used to select individuals for prophylaxis must be chosen carefully, in view of the costs associated with carrying out and supervising such prophylaxis. The Mantoux test was used to obtain measurements on adolescents in metropolitan Victoria and on a small sample of adolescents with clinical TB. These data are employed to obtain estimates and to construct upper confidence bounds for the conditional probability of TB infection, given the level of Mantoux response. Two conservative methods are presented; one is ‘nonparametric’, the other ‘semiparametric’. The analyses indicate that for responses up to and including 13 mm, the probability of TB infection is less than.07 with ninety-five percent confidence.     

A hybrid EM/Gauss-Newton algorithm for maximum likelihood in mixture distributions

A faster alternative to the EM algorithm in finite mixture distributions is described, which alternates EM iterations with Gauss-Newton iterations using the observed information matrix. At the expense of modest additional analytical effort in obtaining the observed information, the hybrid algorithm reduces the computing time required and provides asymptotic standard errors at convergence. The algorithm is illustrated on the two-component normal mixture.     

Measuring the US non-profit sector: a progress report

The input-output model currently used for estimating the size, scope and dimensions of the non-profit sector in the US economy is based on the SIC system. Unfortunately, this system is inadequate to provide detailed information on the non-profit sector. In response, we developed a classification system — the National Taxonomy of Exempt Entities (NTEE) — to define and measure the sector more accurately. This article describes the relationship between the SIC-based measures and the NTEE based measures, and reports on current efforts to link the NTEE system with tax data bases maintained at the Internal Revenue Service.Virginia Hodgkinson is Vice President for Research at Independent Sector, Washington, DC, 20036.Murray Weitzman is a Senior Research Consultant at Independent Sector.     

Normalisation and the psychology of ‘mental retardation‘1

The 1950 and 1960s witnessed a revival of interest among psychologists in mental retardation closely associated with the development of a behaviourist model. These developments effected a decisive break in the discourse of retardation by inserting a ‘behaviour’ component into the definition of retardation. This strengthened claims by psychology of professional primacy vis-à-vis medicine. The objective of professional assertion helped create the conditions in which the service model of Normalisation² took root in North America and, to a lesser extent, the UK. As a semi-autonomous discourse, Normalisation provided a vehicle in which elements of contradictory discourses, principally psychology and interactionism, could be appropriated. The interventions which emerged from this comprised a dual strategy of enhanced social integration and the more precise definition and identification of mental retardation.
