This article reports an evaluation of a community intellectual disability offender service over the period from 1990 to 2001. Men who committed sex offenses or sexually abusive incidents (n = 106) and men who committed other types of offenses and serious incidents (n = 78) are compared on personal characteristics, referral sources, forensic details, and outcome up to 7 years after referral. The cohorts are older than one would expect from the criminology literature, and, at about 33%, the incidence of mental illness is consistent with some previous studies. A greater proportion of sex offenders had criminal justice involvement and a formal disposal from court. Fire raising was not overly represented as an offense. There was a higher rate of reoffending in the nonsexual cohort, which persisted up to 7 years. Investigating only reoffenders, there was a considerable amount of harm reduction recorded up to 7 years, statistically significant up to 5 years following initial referral.  相似文献

A Linear Poisson Autoregressive Model: The Poisson AR(p) Model   总被引:1,自引:0,他引:1  
Time series of event counts are common in political scienceand other social science applications. Presently, there arefew satisfactory methods for identifying the dynamics in suchdata and accounting for the dynamic processes in event countsregression. We address this issue by building on earlier workfor persistent event counts in the Poisson exponentially weightedmoving-average model (PEWMA) of Brandt et al. (American Journalof Political Science 44(4):823–843, 2000). We developan alternative model for stationary mean reverting data, thePoisson autoregressive model of order p, or PAR(p) model. Issuesof identification and model selection are also considered. Wethen evaluate the properties of this model and present bothMonte Carlo evidence and applications to illustrate.  相似文献

The position of departmental secretaries has been under debate. There are claims they have been politicised; they have been placed on term appointments. This article examines the careers of departmental secretaries for the last 50 years. It illustrates the changes in their length of tenure, age of departure, mobility and qualifications. The recent profile shows the need for debate about the position and the future of departmental secretaries.  相似文献

Mixed electoral systems seek to combine elements from different voting methods so as to maximise the numbers of individually accountable constituency MPs, while achieving more proportional outcomes in terms of parties' representation. This paper looks in detail at two kinds of mixed systems: variants of the Additional Member System; and AV Plus (or SV Plus). We examine how they would have operated in British conditions during the 1990s—how ballot papers would be structured, how voters respond to them and what electoral outcomes would have resulted. Both approaches offer good prospects for achieving a consensus amongst electoral reformers on an alternative to first-past-the-post elections. We also show how the Jenkins Commission's proposals can be located within the broader development of 'British AMS' by the Labour and Liberal Democrat parties. In addition, we quantify the main impacts of the policy choices which the Commission made in designing the proposed system to be submitted to a referendum. The British case will be a key one for the wider debate in political science about the endogenisation of voting system changes within party systems.  相似文献

A validation study was conducted to demonstrate that deoxyribonucleic acid (DNA) could be successfully extracted from human nail material and analyzed using short tandem repeat (STR) profiling and/or mitochondrial DNA (mtDNA) sequencing. This study involved the development of a DNA extraction protocol that includes a cleaning procedure designed to remove external contaminants (e.g., biological, chemical). This protocol was used to test human nail material that had been soaked in whole blood from a second donor and coated with gold-palladium to simulate scanning electron microscopic analysis. The results showed no indication of a mixture and were consistent with that of the nail donor. Fresh human nail material usually yielded both STR profiles and mtDNA sequence information; however, aged human nail material (approximately eight years old) yielded only mtDNA sequence information. Upon completion of the validation study, the extraction protocol was used for the analysis of a torn fingernail fragment recovered from the scene of a violent homicide in 1983. A partial STR profile and mtDNA sequence information indicated that the fingernail fragment was excluded as originating from the suspect and was, in fact, consistent with originating from one of the victims.  相似文献

Adolescence is perhaps the most difficult period of child rearing for parents. This study attempted to identify disciplinary techniques used by parents as perceived by mothers, fathers, and their adolescent children. Results indicated several significant areas of intrafamilial disagreement in regard to disciplinary techniques utilized, although all subjects tended to agree that some form of verbal reasoning was the primary disciplinary technique utilized with these adolescents.This study was funded, in part, by the Ohio Agricultural Research and Development Center (H-644) and the School of Home Economics, The University of Georgia.Received his Ph.D. in child and family studies from the University of Tennessee. Current interests include adolescent development, family influences on sex-role development, and dual-work families.Received her Ph.D. in sociology from Iowa State University. Major interests include family research methodology, assessment of family power, and marital dissolution.Received her Ph.D. in educational psychology from the University of Texas. Current research interests include parenting, sex roles, and socialization across the life-span.  相似文献

This study was divided into two parts. The first part consisted of an investigation of the frequency of television viewing among a sample of 2302 15-year-olds in 12 comprehensive schools. Subjects were divided into two groups, high and low frequency viewers, according to their own estimate of viewing time. The general picture which emerged (with some overlap of scores) was that high frequency viewers tended to be more neurotic and introverted; less intelligent; had less favorable attitudes to school; were less likely to think sport was important; were more likely to be bored in their leisure time; and possessed different social attitudes than low frequency viewers. The second part of the study investigated the program preferences of a subsample of over 900 subjects drawn from the main study. Little difference was found in the program preferences of high and low frequency viewers, but clear differences of preference were found between the sexes.Received his Ph.D. from the University of Aberdeen. Main research interests include social factors influencing education, adolescence, sports psychology, community education, and social psychology.Received her M.Ed. from the University of Aberdeen. Main research interests include community education and television.  相似文献

In an era of democratic discontent, more and better participation in policy making has become a standard expectation. Yet it is rarely clear what counts as participation, and how the many practices loosely bundled under the label should be understood. This paper has a modest undergrowth‐clearing objective: to examine assumptions behind competing typologies of participation, and to propose a classification framework less laden by idealist notions of democracy.  相似文献

The prevalence of cardiac implantable electronic devices (CIEDs), pacemakers and implantable cardioverter defibrillators (ICDs) is increasing. However, postmortem analysis of CIEDs is not performed routinely. Fourteen consecutive CIEDs were analyzed. The indication for and date of implantation, technical data, CIED reprogramming, heart rhythm disturbances, patient demographics and medical consultations were investigated. Death during the first year after implantation was seen in 54%, whereof 71% consulted a physician within 10 days before death. The time of death was attributed to a particular day in 29%. There was a relationship between CIEDs and cause/manner of death in 50%. Although limited by a small sample size, this study advocates the routine postmortem CIED analysis for forensic and clinical purposes in selected cases. Patients with CIEDs seem to show an increased risk of death during the first year after implantation. The analysis of CIEDs can be helpful in evaluating the time/cause/manner of death.  相似文献

Abstract

What is ‘relational theorizing’ in International Relations and what can it offer? This article introduces a thematic section that responds to these questions by showing two things. First, relational theorizing is not a doctrine or a method, but a set of analyses that begin with relations rather than the putative essences of constitutively autonomous actors. Second, relational theorizing has emerged from different geo-linguistic traditions, and a relational approach to International Relations (IR) can offer the language and space for increased and productive engagement beyond Anglophone scholarship. This thematic section takes a significant step in this direction by staging a dialogue between Sinophone and Anglophone scholarship on relational IR theorizing. Such an engagement shows points of comparison and contrast, convergence and divergence. In this way, the essays presented here contribute to developing a more ‘global’ IR.  相似文献
