Objective
Child maltreatment constitutes a strong risk factor for violent delinquency in adolescence, with cumulative experiences of maltreatment creating increasingly greater risk. Our previous work demonstrated that a universal school-based violence prevention program could provide a protective impact for youth at risk for violent delinquency due to child maltreatment history. In this study we conducted a follow-up to determine if participation in a school-based violence prevention program in grade 9 continued to provide a buffering effect on engaging in acts of violent delinquency for maltreated youth, 2 years post-intervention.Methods
Secondary analyses were conducted using data from a cluster randomized controlled trial of a comprehensive school-based violence prevention program. Students (N = 1,722; 52.8% female) from 20 schools participated in 21 75-min lessons in grade 9 health classes. Individual data (i.e., gender, child maltreatment experiences, and violent delinquency in grade 9) and school-level data (i.e., student perception of safety averaged across students in each school) were entered in a multilevel model to predict violent delinquency at the end of grade 11.Results
Individual- and school-level factors predicting violent delinquency in grade 11 replicated previous findings from grade 9: being male, experiencing child maltreatment, being violent in grade 9, and attending a school with a lower perceived sense of safety among the entire student body increased violent delinquency. The cross-level interaction of individual maltreatment history and school-level intervention was also replicated: in non-intervention schools, youth with more maltreatment in their background were increasingly likely to engage in violent delinquency. The strength of this relationship was significantly attenuated in intervention schools.Conclusions
Follow-up findings are consistent with the buffering effect of the prevention program previously found post-intervention for the subsample of youth with maltreatment histories.Practice implications
A relative inexpensive school-based violence prevention program that has been shown to reduce dating violence among the whole student body also creates a protective effect for maltreated youth with respect to lowering their likelihood of engaging in violent delinquency. 相似文献152.

We present results from a course, “Informal Science Education for Scientists: A Practicum,” co-taught to graduate students
in STEM-related fields by a scientist/engineer and a social scientist/humanist. This course provides a structured framework
and experiential learning about informal science education during a semester-long experience. The data collected across six
years of the course (11 ≤ n ≤ 16 for each) provide strong evidence that the course has been effective in encouraging graduate
students in STEM-related fields to feel more skilled at and confident with informal science education. Details are provided
as to how manipulation of the course structure (i.e. making it project-based, emphasizing understanding audiences, stressing
the iterative nature of design, and increasing evaluation research training) influenced the student outcomes. 相似文献

Peer group status as a moderator of group influence on children's deviant, aggressive, and prosocial behavior 总被引:2,自引:1,他引:1
Group status was examined as a moderator of peer group socialization of deviant, aggressive, and prosocial behavior. In the fall and 3 months later, preadolescents and early adolescents provided self-reported scores for deviant behavior and group membership, and peer nominations for overt and relational aggression, prosocial behavior, and social preference. Using the social cognitive map, 116 groups were identified involving 526 children (282 girls; M age=12.05). Hierarchical linear modeling revealed that high group centrality (visibility) magnified group socialization of relational aggression, deviant behavior, and prosocial behavior, and low group acceptance magnified socialization of deviant behavior. Results suggest group influence on behavior is not uniform but depends on group status, especially group visibility within the larger peer context. 相似文献

A socialization model of coping with community violence was tested in 101 African American adolescents (55% male, ages 9-13) and their maternal caregivers living in high-violence areas of a mid-sized, southeastern city. Participants completed interviews assessing caregiver coping, family context, and child adjustment. Caregiver-child dyads also discussed a film clip depicting community violence. Parental coaching (caregivers' strategies suggesting how to cope) and child-reported coping were coded from the discussion. Coaching, modeling (caregivers' own coping), and family context each contributed to children's coping with violence. Children's problem-focused coping in response to violence had the strongest associations with changes in their adjustment 6 months later. Implications for interventions with youth and families are discussed. 相似文献

Hue discrimination abilities of giant pandas were tested, controlling for brightness. Subjects were 2 adult giant pandas (1
male and 1 female). A simultaneous discrimination procedure without correction was used. In five tasks, white, black, and
five saturations each of green, blue, and red served as positive stimuli that were paired with one or two comparison stimuli
consisting of 16 saturations of gray. To demonstrate discrimination, the subjects were required to choose the positive stimulus
in 16 of 20 trials (80% correct) for three consecutive sessions. Both subjects reached criterion for green and red. The female
subject also reached criterion for blue. The male was not tested for blue. This study is a systematic replication of Bacon
and Burghardt’s (1976) color discrimination experiment on black bears. The results suggest that color vision in the giant
panda is comparable to that of black bears and other carnivores that are not strictly nocturnal. 相似文献

As part of a library initiative to foster information literacy, promote academic integrity, and prevent inadvertent plagiarism, a high-quality online tutorial was designed to teach students to cite sources properly. The development of this tutorial, APA Exposed: Everything You Always Wanted to Know About APA Format but Were Afraid to Ask, was a collaborative endeavor among research and instruction librarians, learning technology specialists, and an instructor. This study employs a mixed-methods research approach that combines the use of multiple data sources – an online survey, website visitor-tracking software, e-mail correspondence, and a Google search – to evaluate the quality and efficacy of the tutorial. Analyses of online survey data indicate 98% of survey respondents found the tutorial useful or very useful. All of the respondents reported the tutorial improved their understanding of APA style. In addition, 93% of respondents said they planned to use this tutorial as a reference resource in the future and 99% said they would recommend the tutorial to others. The online tutorial received an average of 1055 visits per month. The findings of this study indicate that there is a need for high-quality online citation instruction and that the tutorial meets this need. Providing effective citation instruction online not only benefits tutorial participants but also research and instruction librarians as they can now allocate limited library resources to areas of instruction other then proper citation techniques. 相似文献

Museum visitors are an ideal population for assessing the persistence of the conceptual barriers that make it difficult to grasp Darwinian evolutionary theory. In comparison with other members of the public, they are more likely to be interested in natural history, have higher education levels, and be exposed to the relevant content. If museum visitors do not grasp evolutionary principles, it seems unlikely that other members of the general public would do so. In the current study, 32 systematically selected visitors to three Midwest museums of natural history provided detailed open‐ended explanations of biological change in seven diverse organisms. They were not told that these were evolutionary problems. Responses were coded as: informed naturalistic reasoning, featuring some understanding of key evolutionary concepts, novice naturalistic reasoning, featuring intuitive explanations that are also present in childhood, and creationist reasoning, featuring supernatural explanations. All visitors were mixed reasoners, using one or more of these patterns in different permutations across the seven organisms: 72% used a combination of informed naturalistic reasoning and novice naturalistic reasoning, while a further 28% added creationist reasoning to this mix. Correlational analyses indicated that for many visitors these reasoning patterns were coherent rather than fragmented. The theoretical model presented in this article contributes to an analysis of the developmental and cultural factors associated with these patterns. This could help educators working in diverse educational settings understand how to move visitors and students toward more informed reasoning patterns. © 2009 Wiley Periodicals, Inc.
