黑人性神话与他者身份的建构及其解构——从《土生子》中的跨种族性关系谈起

理查德.赖特的代表作《土生子》被誉为美国黑人文学史上的里程碑式作品、＂抗议小说＂的扛鼎之作,因此学界针对《土生子》的研究多集中于黑白二元对立上,着重探讨的是美国社会制度和种族歧视对美国黑人心灵的戕害及其灾难性后果。在此基础上,本文尝试采用新的视角,以跨种族性关系为切入点,重新审视小说主人公别格的悲剧成因,并且通过分析书中白人如何利用虚假的黑人＂性神话＂构建黑人的他者身份,揭示别格杀害白人姑娘玛丽的讽刺性寓意,彰显＂抗议小说之父＂赖特解构黑人＂性神话＂的创作智慧。     

Response and interventions into harmful sexual behaviour in schools

Internationally young people report experiencing sexual abuse and violence within schools. Developments within the field of adolescent sexual harm are increasingly recognising the need for ecological approaches to harm. Yet, to date, interventions with young people displaying harmful sexual behaviours have prioritised individual behaviours and characteristics over place-based interventions.This article presents empirical evidence from a mixed-methods study aimed at understanding the enablers and barriers to preventing and responding to harmful sexual behaviour in schools. Research was carried out in seven schools and four multi-agency partnerships in England, UK. Using evidence from focus groups, observations, case reviews and policy analysis the article outlines nine components that enable, or are barriers to, effective responses and interventions into harmful sexual behaviour in schools. The paper concludes that responses and interventions into harmful sexual behaviour must move beyond responding to individual behaviours to intervening within factors within schools themselves.     

Child welfare characteristics in a sample of youth involved in commercial sex: An exploratory study

BackgroundHomeless, runaway, and youth exiting foster care are vulnerable to sexual exploitation, but little research has parsed the societal, community, and individual factors that contribute to their risk.Objectives(1) To estimate child welfare characteristics in a sample of homeless young people who engaged in commercial sex (CS); and (2) To compare young people who were sex trafficked (ST) to those who engaged in some other form of CS.Participants and settingThis study includes 98 homeless young people in Philadelphia, PA, Phoenix, AZ, and Washington, DC, who were interviewed for a larger study of ST and endorsed engagement in CS.MethodsWe used a non-probability, purposive, maximum variation sampling procedure. Interviews were recorded and responses were simultaneously noted on a standardized interview form. Data were analyzed through means, frequencies, and bivariate tests of association.ResultsAverage age of the full sample of 98 homeless young people was 20.9 years; 48% were female and 50% were Black/African American. Forty-six percent of the full sample was sex trafficked. The full sample and the victims of ST differed significantly in three child welfare characteristics, with the ST group more likely to have been maltreated as children, more likely to have had family involvement with the child welfare system (CWS), and more likely to report higher rates of living someplace other than with their biological parents as children.ConclusionsST victims differ from those who engaged in other forms of CS in histories of maltreatment, involvement with the CWS, and exposure to residential instability while growing up.     

‘Snitches get stitches’: School-specific barriers to victim disclosure and peer reporting of sexual harm committed by young people in school contexts

BackgroundSchool based, peer-to-peer sexual harm is under-researched despite its prevalence and adverse effects on young people across the globe. Understanding barriers to victim disclosure and peer reporting might help towards the prevention and protection of young people.ObjectiveThis study explores dual perspectives of young people and educational staff about school-specific environmental barriers to 1) young people’s disclosure of sexual harm experienced, and 2) young people’s reporting of sexual harm on behalf of others.Participants and setting: Participants include 59 young people aged 13–21 and 58 educational staff, drawn from seven schools across four local authorities in England whom formed part of a wider study on harmful sexual behavior and safety in schools.MethodsFocus groups were carried out with young people and education staff. The sessions were thematically analysed and focused on barriers to disclosure within the school context.ResultsPeer groups set powerful ‘rules’ that influence the ability and willingness of young people to report sexual harm. Some school responses for addressing sexual harm are sub-optimal and sexual harm is not adequately prioritised. Some schools appear to struggle to manage more subtle forms of sexual harm compared with more recognized forms of violence and abuse. A significant proportion of sexual harm is so prevalent that it is ‘normalised’, and therefore under-reported. This resigned acceptance to sexual harm consequently shapes young people’s disclosures.ConclusionsSchool systems of responding to sexual harm require strengthening to increase feelings of safety and empowerment of young people.     

A mediational model linking perceptions of security,alexithymia and behavior problems of sexually abused children

BackgroundPerceptions of security toward parents are related with internalized and externalized problems among victims of child sexual abuse (CSA). Alexithymia, which is difficulty in identifying and expressing feelings, is associated with the quality of parent-child relationships (Oskis et al., 2013) and behavior problems in children (Di Trani et al., 2013).ObjectiveThe current study tested the mediational role of alexithymia in the relationship between perceptions of security toward parents and behavior problems among CSA victims.Participants and methodUsing a short-term multi-informant prospective design, 263 victims of CSA aged 6–12 years completed the Kerns Security Scale (Kerns, Klepac, & Cole, 1996), which evaluates perceived attachment security to mothers and fathers. Parents completed the Child Behavior Checklist (Achenbach & Rescorla, 2001) at Time 1 to provide baseline scores of behavior problems and again four months later. At Time 2, parents also assessed the children’s alexithymia using the Children’s Alexithymia Measure (Way et al., 2010).ResultsPerceptions of security were both associated with alexithymia, as well as with internalizing and externalizing problems (p < .05). A mediational model showed that perception of security toward fathers outweighed the mother-child relationship in predicting children’s alexithymia. Path analysis revealed that the father-child relationship predicted decreased behavioral problems at Time 2 through a lower level of alexithymia. The model explained 46.9% of internalizing problems and 56.1% of externalizing problems (p < .05).ConclusionsThe findings support the relevance of alexithymia as an intervention target for CSA victims and underscore the importance of the father-child relationship.     

Students’ effort allocation to their perceived strengths and weaknesses: The moderating effect of instructional strategy

To become competent professionals, students should work on both their strengths and weaknesses. Considering students' limited amount of time and energy to work on multiple subjects, it is important to know what determines their allocation of effort to their perceived relative strengths or weaknesses. In a series of five studies, we examined the moderating effect of instructional strategy (i.e., self-directed versus test-directed) on the within-person relation between perceived relative strength (i.e., strengths versus weaknesses) and allocated effort across multiple subjects. We used different methodologies (scenario, field, and experimental studies), research designs (within-person and mixed factorial), populations (secondary school, college, and university students), and measures of effort (intentions, self-reported, and behavioral). The results consistently indicate that students in a self-directed instructional strategy condition tend to allocate more effort to their relative strengths, whereas students in a test-directed instructional strategy condition tend to allocate more effort to their relative weaknesses.
