OBJECTIVES: Since the late 1980s, there has been a strong theoretical focus on psychological and social influences of perpetration of child sexual abuse. This paper presents the results of a review and meta-analysis of studies examining risk factors for perpetration of child sexual abuse published since 1990. METHOD: Eighty-nine studies published between 1990 and April of 2003 were reviewed. Risk factors were classified into one of the following six broad categories: family factors, externalizing behaviors, internalizing behaviors, social deficits, sexual problems, and attitudes/beliefs. Sex offenders against children (SOC) were compared to three comparison groups identified within the 89 studies: sex offenders who perpetrated against adults (SOA), non-sex offenders, and non-offenders with no history of criminal or sexual behavior problems. RESULTS: Results for the six major categories showed that SOC were not different from SOA (all d between -.02 and .14) other than showing lower externalizing behaviors (d=-.25). Sex offenders against children were somewhat different from non-sex offenders, especially with regard to sexual problems and attitudes (d=.83 and .51). Sex offenders against children showed substantial differences from non-offenders with medium sized effects in all six major categories (d's range from .39 to .58). CONCLUSION: Child sex offenders are different from non-sex offenders and non-offenders but not from sex offenders against adults. PRACTICE IMPLICATIONS: This study suggests that the presence of general risk factors may lead to a variety of negative behavioral outcomes, including the perpetration of child sexual offending. Family factors were strongly related to the perpetration of child sex offending (vs. non-sexual offending or non-offending) and may be valuable intervention points for interrupting the development of child sex offending, as well as other negative behaviors. Other potential points for intervention may focus on the development of appropriate social and emotional skills that contribute to sexual offending. 相似文献

Developmental differences in part/whole identification 总被引:1,自引:0,他引:1
At issue in the present research was whether or not preschoolers are able to simultaneously perceive multiple aspects of an object. This issue was examined in 2 experiments in which 3-5-year-olds were asked to describe part/whole pictures (e.g., a "house made of crayons"). Prior developmental research has suggested that preschoolers typically fail to name both part and whole aspects of such pictures. In the present study, parts and wholes ranged from relatively "simple" to relatively "difficult" for preschoolers to identify and label. The results showed that even 3-year-olds frequently named both part and whole aspects of our "simple" pictures but were significantly less likely to name both aspects of more "difficult" pictures. Overall, the results suggest that multiple-aspect perception is available as early as 3 years of age, and that preschoolers' failure in previous studies to explicitly identify both part and whole aspects of the same object may reflect failure in verbal or metacognitive skills rather than in children's ability to perceive multiple aspects of an object. 相似文献

We investigated how overtly aggressive behavior was differentially perceived by two types of perceivers, teachers and peers, as a function of student neighborhood, gender, and grade level. Participants (N= 765) were predominantly African American students in grades 3‐5 recruited from two urban public schools in southern California. The neighborhoods surrounding the two schools differed in levels of identified violent crime and economic levels. Teachers in the community experiencing more violence perceived student behavior to be relatively less aggressive and more similar across genders than did teachers in the less violent community. Peers in the community experiencing more violent crime perceived both boys and girls to be somewhat aggressive, whereas in the less violent community, boys were perceived as aggressive more so than were girls. In general, agreement between teacher and peer perceptions was stronger for boys than for girls. © 2001 John Wiley & Sons, Inc. 相似文献

Increasing diverse author representation within medical librarianship scholarship among BIPOC information professionals is an important endeavor that requires closer examination. This commentary looks to examine the ways in which the profession can support Latinx librarians and library workers in fully participating within the scholarly pipeline by exploring our unique and authentic voices, structural barriers, hesitation and fears, Whiteness in the profession and knowledge production, bias in the peer review process, lack of resources and support, and finally, a call to action. 相似文献

This article focuses on an experienced high school mathematics teacher who changed her practice without participating in planned
interventions aimed at producing this change. It reports on the nature of the teacher’s change from her perspective and an
interpretation and understanding of the change from the researcher’s perspective. It illustrates how meaningful change can
occur when the process is initiated and rooted in the teacher’s experience based on a tension in self and/or practice that
is personal and real to him or her. It discusses three types of change that are possible depending on the level of engagement
of the teacher in professional development opportunities: instrumental change, conceptual change, and foundational change. 相似文献

Due to its importance in fitness centers, a number of authors have explored and analyzed loyalty. However, two characteristics not yet examined are service convenience in fitness center chains and low-cost fitness centers (an emerging business model). In the present study, the authors sought to understand the relationship among perceived quality and service convenience on perceived value, satisfaction, and client loyalty in low-cost fitness centers. Clients (N = 763; 381 women and 382 men) from three low-cost Spanish fitness centers were surveyed, revealing a positive relationship among the variables studied. Findings demonstrate the importance of proper management of non-monetary sacrifices and perceived quality by the managers of these sport organizations, since client loyalty could depend on factors of these emerging sport models. 相似文献

This study investigates the impact of an innovative conservation action campaign called Penguin Promises implemented at uShaka Sea World in Durban, South Africa. Communication tools included interpretive signage, exhibits with and without animals, presentations, and personal interactions, along with a specially designed postcard, on which visitors could write a promise (pledge) to make a change in their daily lives to become more environmentally responsible. Visitors who completed a card were contacted a year or more after their visit and asked about the outcomes of their promise. The results (N = 316) showed that 49.4% of respondents could give an example of something positive they had done for the environment, that they attributed to the campaign. Based on the study, recommendations are provided for the design of effective visitor conservation action campaigns. 相似文献
