Certain family factors, including dynamics, interactions and communication patterns, experiences of intra-familial victimisation, overall functioning and attachment can increase propensities for the commission of a sexual crime and may even be linked to recidivism. However, there is an absence of research that examines factors that contribute to problematic family relationships and how youth and caregivers vary in perceptions of family relationships. The current cross-sectional research study delivered the same validated instruments to youth (n?=?46) and their caregivers (n?=?46) to determine relative perceptions of family relationships and stress. Two multiple regression models were conducted to determine factors that contribute to problematic family relationships. Youth reported greater stress scores and more problems in family relationships relative to caregivers. Stress contributed to family relationship problems for youth and caregivers, but protective factors were associated with less family relationship problems for caregivers. Treatment and research implications are discussed.  相似文献

Shirking in the Contemporary Congress: A Reappraisal   总被引:1,自引:0,他引:1

Vander Wielen Department of Political Science, Washington University in St. Louis, Campus Box 1027, One Brookings Drive, St. Louis, MO 63130 e-mail: e-mail: rjvander{at}artsci.wustl.edu This paper replicates the findings that appeared in the article"Severing the Electoral Connection: Shirking in the ContemporaryCongress," published in the American Journal of Political Science(44:316–325), in which Lawrence Rothenberg and MitchellSanders incorporated a new research design and, contrary toall previous studies, found evidence of ideological shirkingin the U.S. House of Representatives. We investigate the robustnessof their results by reestimating their model with Congress-specificfixed effects and find that their results no longer hold.  相似文献

Photodegradation and laser desorption mass spectrometry (LDMS) is a powerful combination of methods capable of characterizing dyes found in pen inks. Rhodamine dyes in pens that contain red ink were analyzed directly from paper (no extraction step is necessary). Inks exposed to incandescent light form photodegradation products (compounds with lower molecular weights than that of the intact dye) and in some instances, photoproducts (compounds with higher molecular weights than that of the intact dye). The degradation products and photoproducts can be detected with LDMS, and the results can be used for dye identification. Advantages include: (1) the instrumental analysis takes less than a minute; (2) sample preparation is minimal; (3) LDMS is a minimally destructive technique; (4) incandescent light sources are inexpensive, safe to use, and readily available; and (5) isomeric dyes can be distinguished.  相似文献

The effects of redistricting on candidate entry patterns in contemporary House races has received growing attention in the scholarly literature, yet virtually no consideration has been given to this question in the context of historical elections. This is unfortunate as the wider variation in congressional redistricting during the nineteenth century gives us increased leverage in terms of understanding strategic candidate behavior. Utilizing a new dataset of candidate quality for nineteenth-century House races, we examine whether candidates with prior electoral experience are more likely to run in districts that are altered during the redistricting process, and provide an account of how differences in the prevalence of redistricting may affect strategic entry decisions of politicians. Our results suggest that entry decisions and electoral outcomes are affected by redistricting in this era. Moreover, our analysis provides an opportunity to use history to test contemporary theories of congressional elections in a broader context .  相似文献

As public awareness of and concern about sexual victimization has increased in recent decades, stigmatization of sex offenders has also increased considerably. Contemporary sex offender policies transform discrete criminal behaviors into lifelong social identities. Although there is much debate about the efficacy and constitutionality of such policies, we know little about how the category of “sex offender” is constituted in the first place. In this article, I reveal how prosecutors and defense attorneys construct sex offenders, not as monsterous or racialized as is commonly thought, but as “lower class” men. This analysis is based on 30 in‐depth interviews with prosecutors and defense attorneys in Michigan. These legal actors wield disproportionate power in defining the boundaries of criminal behaviors and individuals. That they associate sexual criminality with lower class men demonstrates yet another way that class‐based inequalities are reproduced in the legal field.  相似文献

There is widespread agreement that the Australian ballot fundamentally altered the American electoral system. One common approach to test the effects of ballot reform is to examine legislators elected under the party and secret ballot. An alternative research design, which we adopt here, compares changes in the behavior of legislators who were elected under both ballot types. We use this approach to investigate whether ballot reform directly influenced legislators' decisions to seek renomination and their behavior within the institution. Our results raise a number of important implications for understanding the effects of electoral reform on political behavior.  相似文献

The implementation of international humanitarian law (IHL) is a continuous and evolving process. As such, the International Committee of the Red Cross (ICRC) co-operates closely with the Commonwealth Secretariat with the aim to advise and support Commonwealth states on developments in IHL and to assist them in meeting their IHL treaty obligations. The present update highlights some of the key issues and recent developments in IHL that are of interest to Commonwealth states.  相似文献

Abstract

Cognitive Analytic Therapy (CAT) is a collaborative time-limited psychotherapy developed by Ryle. The approach aims to formulate how early experiences influence the development of unhelpful patterns that maintain a person's current difficult experiences. Within the UK, forensic services personnel are increasing their uses of CAT approaches within contextual, i.e. treatment teams, settings. Offending behaviour is relational (perpetrator to victim), and CAT is a relational model. Within the context of National Health Service consultation service (Serious Offender Liaison Service) working with the Police and Criminal Justice Social Work to assess, formulate and give advice regarding working with serious sexual and violent offenders, often with personality disorders, a case example is presented. The paper suggests that utilising a relational model, such as CAT, and applying one of the main the tools of this approach, through diagrammatic representations (maps) of the formulation, can enable agencies working with an individual to share a common formulation and language.  相似文献

Purpose

Several studies have observed a relationship between academic achievement and externalizing behaviors, both of which are predictors of delinquency and criminal behavior in adulthood. There is, however, no consensus on an explanation for their co-occurrence. One perspective is that both emerge as a result of a common underlying factor. This study investigates the degree to which the same genetic and environmental factors account for the co-occurrence of these two outcomes.

Methods

The sample consists of twins (N = 360) from the Early Childhood Longitudinal Survey-Kindergarten Class of 1998-1999. Bivariate genetic analyses were conducted to assess the genetic and environmental influence on the relationship between academic achievement and externalizing behaviors during kindergarten.

Results

The covariation was due primarily to common shared environmental factors (55-87%), followed by common genetic (8-44%) and nonshared environmental factors (1-13%).

Conclusions

Both early academic achievement and externalizing behaviors are partially influenced by the same genetic and environmental factors. The large proportion of covariance attributed to shared environmental influences suggests that identifying and targeting shared environmental factors in prevention and intervention strategies may improve both behavior and academic achievement.  相似文献
