Childhood experiences of physical punishment were examined as related to perceptions of family environment during childhood and affective and personality outcomes of college students. From the 274 respondents who participated, scores were compared for the participants with the 75 highest and 75 lowest physical discipline scores based on the Conflict Tactics Scale (CTSPC-CA). Respondents who experienced the highest level of physical punishment in their families of origin reported higher family conflict, more negative parental relationships, greater family worries, more depressive symptoms, more perceived nonsupport, greater identity problems, and more negative social relationships. Respondents in the low physical punishment group reported higher positive family affect. Results suggest that experiencing physical discipline as a child may be related to one’s family environment and psychological well-being in young adulthood.  相似文献

The current study examined how antisocial personality disorder (APD) and substance use disorder contributed to partners’ reports of physical partner violence among single and dual substance-abusing couples. Participants were 69 heterosexual couples entering treatment in which one or both partners met criteria for substance use disorder. APD diagnosis of the male partner was linked to significantly higher male-to-female and female-to-male perpetration of physical partner violence and victimization. Female partner’s APD diagnosis was associated with women’s reports of victimization by their male partners. Dual substance use diagnosis emerged as a moderator, in which the effect of men’s APD diagnosis on men’s perpetration of physical partner violence and victimization was significantly reduced if both partners had substance use disorder. Findings underscore the importance of both partners’ APD diagnosis and substance use status for understanding physical partner violence among single and dual substance-abusing couples.  相似文献

This case study exploits matched firm–employee Tunisian data in order to underline the role played by within-firm human capital in worker remuneration. The estimated returns to human capital in wage equations remain unchanged when the dummies representing firm heterogeneity are replaced in the list of regressors with three firm variables: a textile industry dummy, within-firm mean education, and firm age. We find that part of what is usually considered as return to education may be due to within-firm externalities.  相似文献

Discussions in environmental policy often focus on the highest levels of decision making and action while paying scant attention to those individuals on the front lines. Among those frequently overlooked are the individuals at regulated facilities who interact with government regulators on a frequent basis. Interviews with nearly two dozen facility personnel in Virginia yield findings that challenge common perceptions of the relationships between facility personnel and inspectors. In particular, 86 percent of facility personnel, representing a range of regulated facilities from prisons to landfills to dry cleaners, said their interactions with inspectors were positive. Approximately 70 percent of them said that they trust inspectors and provided evidence of trust in their stories. The ramifications of these findings for environmental policy could be potentially significant because facility personnel are presumed to be adversarial, if not outright hostile, and this assumption impacts the design and implementation of environmental regulations.  相似文献

Drones now comprise a major part of our culture – primarily as a consequence of the so-called War on Terror and the rise in violent extremism. Yet the available data on what it means to operate a drone (where this can influence wider perceptions on the appropriateness and effectiveness of remote warfare as an act of counterterrorism) is highly contradictory. This article explores a new source of data capable of shedding light on this contested issue: online interviews with current and former pilots discussing their personal experiences. Access to this testimony has the potential to influence cultural understandings of remote warfare, specifically where these stories highlight the severe psychological difficulties pilots can be subject to. In analysing this new data, however, the article questions whether the media typically employed to express pilot testimony comprises an appropriate space in which to publicise and engage with this evidence. It argues that this presentation has caused these personal accounts to become fetishised – to the extent this undermines the cultural, political, and informative value of the data and even reinforces the narratives of remote warfare this testimony frequently seeks to reverse.  相似文献

Adolescents experience various forms of strain in their lives that may contribute jointly to their engagement in cyber aggression. However, little attention has been given to this idea. To address this gap in the literature, the present longitudinal study examined the moderating influence of peer rejection on the relationship between cyber victimization at Time 1 (T1) and subsequent cyber aggression at Time 2 (T2; 6 months later) among 261 (150 girls) 6th, 7th, and 8th graders. Our findings indicated that both peer rejection and cyber victimization were related to T2 peer-nominated and self-reported cyber aggression, both relational and verbal, after controlling for gender and T1 cyber aggression. Furthermore, T1 cyber victimization was related more strongly to T2 peer-nominated and self-reported cyber aggression at higher levels of T1 peer rejection. These results extend previous findings regarding the relationship between peer rejection and face-to-face aggressive behaviors to the cyber context. In addition, our findings underscore the importance of utilizing multiple methods, such as peer-nomination and self-report, to assess cyber aggression in a school setting.  相似文献

The processing of skeletal material poses several challenges for forensic laboratories. Current methods can be laborious, time-consuming, require dedicated equipment, and are vulnerable to contamination. In this study, various sample mass (1 × 50 mg, 3 × 50 mg, and 1 × 150 mg chip(s)) and incubation times (2, 4, and 16 h) were tested using the PrepFiler® BTA™ Forensic DNA Extraction Kit to digest whole bone chips in lieu of powdering. The most effective method was then applied to bones and tooth fragments collected from contemporary human cadavers exposed to various environmental conditions using an automated platform. Over a third of the samples tested generated full DNA profiles without having to powder the bone/tooth fragment or further alter the manufacturer's protocol. However, for most samples resulting in incomplete STR profiles due to low amounts of DNA, slightly better results were achieved with powdered tissue. Overall, this work demonstrates the potential use of a faster, nonpowdering DNA extraction method for processing skeletal samples as an effective first-pass screening tool.  相似文献

Numerous studies document sex differences in African American girls’ and boys’ academic achievement and motivation, but little is known about how the enactment of gender, such as in the forms of gendered behaviors, attitudes, or personal-social qualities, is related to school functioning. To advance understanding of African American adolescents’ academic experiences, this study examined the longitudinal linkages between stereotypically feminine (i.e., expressive) and stereotypically masculine (i.e., instrumental) personality characteristics and school adjustment. The moderating effects of youth’s ethnic identity and school racial composition also were tested. Participants were 352 African American youth (50.1% girls; mean age at Time 1?=?12.04 years; SD=?2.03) who participated in annual home interviews. Net of biological sex, expressive traits (kind, sensitive) were positively related to school self-esteem and school bonding for both girls and boys, but youth with higher levels of instrumentality (independent, competitive) exhibited sharper declines in academic achievement across adolescence. School racial composition moderated the effects of instrumentality at the between-person level, such that instrumentality was positively related to school self-esteem only for youth who attended schools with fewer African American students. These results highlight the importance of incorporating gendered personality traits, rather than biological sex alone, into theoretical accounts of African American youth’s school functioning.
