Characteristics of children with problem sexual behaviour and adolescent perpetrators of sexual abuse: a systematic review

ABSTRACT

People who commit sexual offences are a heterogeneous group, with research suggesting that children and young people commit a large proportion of all sex offences, especially those committed against other children. This systematic review provides a synthesis of literature concerning the characteristics of children and adolescents who exhibit harmful sexual behaviour. There is a particular focus in this review on studies that examine the characteristics of children and young people exhibiting these behaviours within institutional and organisational settings or which take a situational and/or developmental approach to understanding sexually abusive behaviour. Using a developmental and life-course criminology lens, this review explores implications from the literature for the prevention and response to child sexual abuse, with a particular focus on institutional contexts where the perpetrators are children and adolescents.     

Focal Points and Turning Points in Negotiation: A Comparative Analysis

In this article, we examine the roles of focal points and turning points in negotiation. Both concern impasses in negotiation, and negotiators can exploit them to move past impasses. Each term uses the word “point” differently, however. A focal point refers to a single salient coordinating concept shared by the parties. A turning point is a departure that takes place during the course of a negotiation, when the course seems to change. Precipitants precede turning points and consequences follow them. In this article, we focus on the relationship of these two negotiation concepts. We raise the following questions: Does the development of focal points precipitate departures, and, if so, how? Do departures lead to the development of focal points, and, if so, how? Are there circumstances in which focal points do not precipitate turning points and vice versa? Do negotiations that feature focal points create more or less durable agreements? Do negotiations that include turning points create more or less durable agreements? To help answer these questions, we have analyzed four cases. In the German Foundation Agreement negotiation, the development of focal points precipitated turning points. In the South African Interim Constitution negotiations, turning point departures precipitated the development of focal points. And in the negotiations to end the Burundi civil war and to reach the Nouméa Accord between France and New Caledonia, parties shared focal points that did not precipitate turning points. These case analyses provide insights into the role of focal points in producing effective and durable agreements. They also suggest opportunities for further research on the interaction between these concepts.     

Evaluation of Mastoid Process as Sex Indicator in Modern White Americans using Geometric Morphometrics

Conventional methods for evaluating the mastoid as a sex indicator cannot determine whether mastoid shape is an independent and reliable sex indicator. Here, shape differences between the mastoids of 100 male and 100 female modern white Americans were statistically analyzed and visualized using the geometric morphometric method. Discriminant analysis was performed on mastoid size and shape. The relation between size and shape was analyzed to examine the effect of size on shape. In the results, mastoid size and shape were statistically significant sex indicators, while size factor explained 87.3% of the total variance of the shape variables. Nevertheless, females had relatively broader and shorter mastoid shape than males regardless of size, reflecting 12.7% of the total variance of the shape variables. In conclusion, mastoid size and shape were statistically significant sex indicators, while size may matter more in the mastoid than in other cranial parts in terms of sexual dimorphism.     

Secular Change in Morphological Pelvic Traits used for Sex Estimation

This research evaluates secular change in Phenice's (Am J Phys Anthropol, 30, 1969 and 297) three morphological traits of the pubis, as described by Klales et al. (Am J Phys Anthropol, 149, 2012 and 104): medial aspect of the ischio‐pubic ramus, subpubic contour, and ventral arc. Ordinal scores were collected for these traits and compared between a sample of innominates from the historical Hamann–Todd Collection (n = 170) and modern Bass Donated Collection (n = 129). Using the Freeman–Halton test, significant differences between temporal sample score frequencies were found for all traits in females and for the subpubic contour and ventral arc in males. Despite these findings, classification accuracy using logistic regression between the temporal periods remained low (68.7%). These results suggest that secular changes in trait expression are occurring; however, sex estimation methods using these traits and created with historical samples are still applicable to modern forensic cases. In fact, the secular changes occurring in these traits contribute to better classification accuracy between sexes in modern populations.     

A Criminal Career Study of the Continuity and Discontinuity of Sex Offending during the Adolescence-Adulthood Transition: A Prospective Longitudinal Study of Incarcerated Youth

Longitudinal research has seriously challenged assumptions that juvenile sex offenders (JSO) are characterized by high level of dangerousness, mental health problems, and crime specialization in sex offenses. The current study examines the longitudinal pattern of offending among a sample of JSO and a sample of juvenile nonsex offenders. The research design includes longitudinal data over a nine-year period allowing the examination of offending patterns and the crime mix from age 12 to age 23. The findings highlight that, while JSO are prone to persist offending in adulthood, there is limited continuity of sex offending. Further, the findings stress the importance of taking into account nonsexual juvenile delinquency, more specifically, youth violence, to make a better assessment of early adult offending outcomes of JSO.     

社会性别视角中的两性平等

社会性别相对于生理性别而产生的,是近年来国际上分析男女平等的重要概念。从社会性别的视角来看,影响两生平等的因素,主要有理论、经济、政治和文化等方面。实现两性平等对于弘扬先进文化,建设和谐社会具有十分重要的意义。     

Competing Risks, Persistence, and Desistance in Analyzing Recidivism

A statistical procedure is developed to analyze recidivism in samples whichare subject to the presence of desisters and to multiple modes ofreconviction. This allows for a more accurate study of individuals'transition and hazard in the type and timing of offenses following aspecific type of conviction. The use of a nonparametric approach forinvestigating failure in the presence of other acting causes is shown;initial estimators of the probabilities of reconviction for different typesof offenses are obtained, and the method can be used both to display thedata and to choose an appropriate parametric family for the survivaltimes. An exponential mixture model for competing risks is presented insuch a way that it allows us to adjust for concomitant variables and toassess their effects on the probabilities both of reconviction forpredetermined types of offenses and desistance and of the hazards ofreconviction; a method for assessing calibration of predicted survivalprobabilities is suggested. A 21-year follow-up of persons convicted ofindecent assault on a female in 1973 illustrates the methods; we find ahigh probability of sexual reconviction for individuals with previoussexual convictions and evidence of diversity and a raised hazard ofreconviction for young chronic offenders.     

经济增长、社会发展与男孩偏好:基于治理的视角

本文基于1990、2000年全国人口普查数据和1995、2005年全国1%人口抽样调查数据,采用了多层线性模型(HLM)方法,对经济增长、社会发展和男孩偏好之间的关系进行了分析。发现较高的经济增长水平和社会发展程度有助于出生人口性别比治理绩效的实现,但受到男孩偏好强弱程度的影响。论文结尾分析了研究结论对于出生人口性别比治理的政策启示,并指出了局限性和未来改进方向。     

Where Registered Sex Offenders Live: Community Characteristics and Proximity to Possible Victims

Recent developments in sanctions for sex offenders emphasize use of sex offender registries and residential restrictions in efforts to raise public awareness and keep offenders away from possible victims. One consequence of such efforts is to relegate registered sex offenders to socially disorganized communities. The present study draws on census tract level data from one urban county and assesses whether offenders are likely to be found in socially disorganized communities and in communities with high concentrations of potential victims. Findings show that registered sex offenders are more likely to reside in socially disorganized and disadvantaged communities, but not in locations with large pools of most types of possible victims (e.g., women living alone, children). Residential location is explained in terms of economic factors, not desire to live near possible victims. Implications for current policies and practices are discussed.     

Level Two Negotiations: Helping the Other Side Meet Its “Behind‐the‐Table” Challenges

A long analytic tradition has explored the challenge of productively synchronizing “internal” with “external” negotiations, with a special focus on how each side can best manage internal opposition to agreements negotiated “at the table.” Implicit in much of this work has been the view that each side's leadership is best positioned to manage its own internal conflicts, often by pressing for deal terms that will overcome internal objections and by effectively “selling” the agreement to key constituencies. Far less frequently have analysts considered how each side can help the other side with its “behind‐the‐table” barriers to successful agreement. Following Robert Putnam's two‐level games schema, I characterize such “behind‐the‐table” or “Level Two” barriers more broadly, offer several innovative examples of how each side can help the other overcome them, and develop more general advice on doing so most effectively. As a fuller illustration of a Level Two negotiator helping the other side with its formidable behind‐the‐table challenges, I pay special attention to the end‐of‐Cold‐War negotiations over German reunification in which former American Secretary of State James Baker played a key role.
