Do elementary school‐based child abuse prevention programs work? A high school follow‐up     

Susan F. Ko  Merith A. Cosden 《Psychology in the schools》2001,38(1):57-66

Despite the widespread use of school‐based abuse prevention programs, few studies support their effectiveness in helping children avoid victimization. Most studies that evaluate prevention programs measure changes in children's knowledge and not subsequent behavior. Further, the link between knowledge, behavior, and the ability to avoid or reduce victimization has not been established. In this study the impact of a school‐based prevention program was assessed by surveying students at a high school in southern California where students from feeder elementary and junior high schools were known to have had abuse prevention programs available to them. Data were collected anonymously on 137 high school students during their Health class. A quasi‐experimental design was utilized, comparing the 72 students who had attended one or more school‐based abuse prevention program with the 65 who stated they had not participated in a prevention program. Demographic similarities between the two groups were established. Students who attended prevention programs were more knowledgeable about abuse concepts and reported fewer incidents of abuse. However, the effectiveness of students' responses to abuse, even when they were using strategies taught by the prevention programs, was variable. Questions about the effectiveness of these strategies with familial and nonfamilial abuse are discussed. © 2001 John Wiley & Sons, Inc.  相似文献   

Self-Efficacy Beliefs and Mathematical Problem-Solving of Gifted Students   总被引：2，自引：0，他引：2  

Frank Pajares 《Contemporary educational psychology》1996,21(4):325-344

Path analysis was used to test the predictive and mediational role that self-efficacy beliefs play in the mathematical problem-solving of middle school gifted students (n= 66) mainstreamed with regular education students (n= 232) in algebra classes. Self-efficacy of gifted students made an independent contribution to the prediction of problem-solving in a model that controlled for the effects of math anxiety, cognitive ability, mathematics GPA, self-efficacy for self-regulated learning, and sex. Gifted girls surpassed gifted boys in performance but did not differ in self-efficacy. Gifted students reported higher math self-efficacy and self-efficacy for self-regulated learning as well as lower math anxiety than did regular education students. Although most students were overconfident about their capabilities, gifted students had more accurate self-perceptions and gifted girls were biased toward underconfidence. Results support the hypothesized role of self-efficacy in A. Bandura's (1986) social cognitive theory.  相似文献

Time-in/time-out as a response to noncompliance and inappropriate behavior with children with developmental disabilities: Two case studies     

D. Joe Olmi  Robert C. Sevier  Deborah F. Nastasi 《Psychology in the schools》1997,34(1):31-39

Time-in and time-out were used to treat inappropriate and noncompliant behaviors in a child with severe language disabilities and a child with a moderate mental disability and cerebral palsy. The target behaviors for Jeremy were compliance with first-time presented teacher instructions, elopement and aggression. Prior to intervention, archival baseline data for Jeremy suggested a compliance rate with teacher directives of approximately 9% and a high frequency of elopement and aggression. Following implementation of a compliance training package, compliance to teacher directives increased to 97% within the first week of intervention and minimal instances of elopement and aggression. Two, 24, and 40-week follow-up compliance checks yielded mean rates of 98%, 99%, and 98% respectively and no elopement or aggression. Reduction in object tossing behaviors was targeted for Jenny. Archival baseline, indicated through parent report, suggested tossing rates of 80% of the times objects were in hand. Frequency of object tossing behavior decreased to a near-zero level during intervention. The use of this intervention package with children in an effort to deter future chronic noncompliance and inappropriate behavior is discussed. © 1997 John Wiley & Sons, Inc.  相似文献

Dielectrophoresis of DNA: Quantification by impedance measurements     

Anja Henning  Frank. F. Bier  Ralph H?lzel 《Biomicrofluidics》2010,4(2)

Dielectrophoretic properties of DNA have been determined by measuring capacitance changes between planar microelectrodes. DNA sizes ranged from 100 bp to 48 kbp, DNA concentrations from below 0.1 to 70 μg∕ml. Dielectrophoretic spectra exhibited maximum response around 3 kHz and 3 MHz. The strongest response was found for very long DNA (above 10 kbp) and for short 100 bp fragments, which corresponds to the persistence length of DNA. The method allows for an uncomplicated, automatic acquisition of the dielectrophoretic properties of submicroscopical objects without the need for labeling protocols or optical accessibility.  相似文献   

Navigating barriers: A qualitative examination of the under-representation of Black females as head coaches in collegiate basketball     

John F. Borland  Jennifer E. Bruening 《Sport Management Review》2010,13(4):407-420

Although sport management researchers have produced findings with regard to diversity in the leadership positions of college athletics, this examination has focused separately on gender (Inglis et al., 1996, Inglis et al., 2000; Inglis, Danylchuk, & Pastore, 2000; Knoppers et al., 1991, National Collegiate Athletic Association, 2009a, Sartore and Cunningham, 2007) or race (Cunningham and Sagas, 2004a, Cunningham and Sagas, 2004b, Cunningham et al., 2001, Cunningham et al., 2006). The current study, framed by intersectionality, identifies barriers contributing to the under-representation of Black women in head coaching jobs in Division I women's basketball in the United States. The assistant coaches cited access discrimination, lack of support, and prevalent stereotypes as barriers. In negotiating these barriers, the women discussed the importance of networking, mentoring and presenting “a proper image” for big-time athletics. To eradicate these barriers, the women recommended expanding job pools; more mentoring by athletic department personnel; and more development programs offered for young Black females.  相似文献   

库珀中心纵向研究：有氧运动的灵魂          下载免费PDF全文

目的：为肯尼斯·库珀（Kenneth H. Cooper）于1970年提出的库珀中心纵向研究（CCLS）提供详细历史。方法：对库珀中心纵向研究人群和库珀诊所所检查的重要参数,以及库珀诊所患者的各种疾病发病率和死亡率进行数据描述。并对近50年来已发表的库珀中心纵向研究的主要研究结果进行总结。结果：在库珀诊所检查期间,通过最大跑台运动测试客观地测量出的心肺功能（CRF）已成为各种疾病发病率和死亡率的强大且独立的风险因素。更具体地说,库珀中心纵向研究明确表明,中高水平的心肺功能与人体全因、心血管疾病和癌症死亡率有显著相关关系。此外,已经证明,中年人群的心肺水平是全因痴呆、Ⅱ型糖尿病、慢性肾病、癌症发病率和存活率以及一些其他慢性疾病的预测因子。因此,库珀中心纵向研究结果还表明,中年人群的心肺水平与老年时期的医疗保健成本呈显著相关。结论：除罕见情况以外,已经进行了近50年的库珀中心纵向研究的研究结果表明,相对于较低水平的心肺功能,中高水平的心肺功能可以有效预防许多疾病。  相似文献   

Conduct disorder and comorbidity     

Nicole D. Stahl  Harvey F. Clarizio 《Psychology in the schools》1999,36(1):41-50

Conduct Disorder (CD) research is focusing on complex issues introduced by comorbidity because of its widespread existence, thoeretical importance and practical significance. This review provides critical examination of research published during the past ten years addressing CD and its comorbid conditions, specifically Attention‐Deficit Hyperactivity Disorder (ADHD), Oppositional Defiant Disorder (ODD), and internalizing disorders. It is concluded that comorbidity varies with age, gender, informant, diagnostic criteria, and nature of the sample (clinical vs. epidemiological). Implications of comorbidity for etiology, diagnosis, treatment, law, and policy and preventive efforts in work with children and adolescents with CD are offered for school psychologists. © 1999 John Wiley & Sons, Inc.  相似文献   

Division of labour and sharing of knowledge for synchronous collaborative information retrieval     

Colum Foley  Alan F. Smeaton 《Information processing & management》2010

Synchronous collaborative information retrieval (SCIR) is concerned with supporting two or more users who search together at the same time in order to satisfy a shared information need. SCIR systems represent a paradigmatic shift in the way we view information retrieval, moving from an individual to a group process and as such the development of novel IR techniques is needed to support this. In this article we present what we believe are two key concepts for the development of effective SCIR namely division of labour (DoL) and sharing of knowledge (SoK). Together these concepts enable coordinated SCIR such that redundancy across group members is reduced whilst enabling each group member to benefit from the discoveries of their collaborators. In this article we outline techniques from state-of-the-art SCIR systems which support these two concepts, primarily through the provision of awareness widgets. We then outline some of our own work into system-mediated techniques for division of labour and sharing of knowledge in SCIR. Finally we conclude with a discussion on some possible future trends for these two coordination techniques.  相似文献
