The present study examines gender differences in bullying in high school. Unique contributions include comparisons of both victimization and perpetration rates across four subtypes of bullying: physical, verbal, relational, and cyber. Further, as we conceptualize bullying within the larger framework of literature on social rejection, we also address whether there are gender differences in experiencing social rejection–in the form of bullying–and responding with aggression, as opposed to asocial or prosocial behavior. The literature yields mixed findings across these three questions (i.e., gender differences in experiences with victimization and perpetration and responses to those experiences), suggesting sample variations (Archer Review of General Psychology, 8(4), 291–322, 2004; Archer & Coyne Personality and Social Psychology Review, 9, 212–230, 2005; Card, Stucky, Sawalani, & Little Child Development, 79, 1185–1229, 2008). Thus, we explored experiential differences in our sample, and hypothesized based on the tend and befriend model (Taylor et al., 2000) that girls would be more likely than boys to respond to bullying with prosocial behaviors. With regard to victimization and perpetration differences, we found that male students both experienced and perpetrated significantly more physical bullying. Boys were also significantly more likely to report experiencing verbal bullying than girls. No significant differences emerged for relational or cyber bullying. With regard to responses, social withdrawal was more common than aggressive responding, but consistent with the tend and befriend model, girls chose prosocial responses significantly more than boys, whereas boys were just as likely to choose antisocial responding as prosocial responding. These results suggest that gender should be considered in studies addressing the question of when experiences with rejection–in its many forms–results in antisocial versus prosocial behavior.  相似文献

Due to the ongoing health crisis among injection drug users in Vancouver, Canada, there have been repeated calls for the establishment of safe injection sites (SISs) since the early 1990s. In April 2003, in response to a large-scale police crackdown and government inaction, a group of activists opened an unsanctioned SIS in Vancouver's Downtown Eastside (DTES). The 327 Carrall Street SIS operated for 181 days despite considerable police harassment and limited financial support. During the operation of the SIS, volunteers supervised over 3000 injections and demonstrated the feasibility of a user-run low-threshold SIS. The experience of the SIS provides valuable lessons for those seeking to advance the interests of injection drug users through community mobilization and direct action approaches. In this article, Thomas Kerr, Megan Oleson, and Evan Wood describe the events surrounding the establishment, operation, and closing of the unsanctioned SIS, and outline the lessons learned.  相似文献

Material recovered from 374 fingerprints left by eleven laboratory workers on three different substrates (glass, wood, metal) at a standard pressure time of 30 s, with and without preliminary handwashing, was submitted to morphological, quantitative, and type analysis. Morphological and agarose-gel electrophoresis analysis showed that a non-negligible amount of epidermal corneal cells presented apoptotic alterations. The quantity of DNA recovered from fingerprints ranged between 0.04 to 0.2 ng, and in a significant number of experiments no DNA was detected. Handwashing reduced the amount of DNA recovered from fingerprints. The "shedder status" of the donor was a very important factor, causing inter-individual variations in the amount of DNA left by fingerprints. Spurious alleles from laboratory-based and secondary transfer contamination, stutters, and other artifacts described when analyzing low-copy-number DNA and capable of affecting correct profiles were observed.  相似文献

Differences between proactive and reactive aggression subtypes on self-reported measures of empathy, social competence, and expectation for reward were examined among 433 middle school students (65.4% White, 33.9% Black). As hypothesized, males scored higher on proactive and reactive aggression scales and lower on empathy measures than females. K-means cluster analysis yielded the following four distinct groups: reactive, proactive, proactive/reactive aggressive, and uninvolved. Overall, uninvolved (nonaggressive youth) had higher empathy and social competence scores and lower expectation of reward for the use of aggression. The reactive and proactive groups did not differ significantly on study variables. Limitations and implications are discussed. Graduate student at the University of Illinois at Urbana-Champaign.

Although Spanish-language media in the USA have grown rapidly since the turn of the century, little scholarship has been dedicated to the semiotic characteristics of these media. This study examines the visual representation of ideologies in 15 news photographs published in Spanish-language print media in the Midwest of the USA with the goals of understanding how ideologies are expressed visually in a culture that has received little treatment in the previous literature and of determining the potential for these photographs to challenge the negative semiotic treatment of Latin@ immigrants in the USA. Following a critical social semiotic approach, the analysis demonstrates how ideologies pattern around the inclusion and exclusion of Latin@s. These ideologies challenge and perpetuate the hegemonic structure, respectively, and as such, indicate the potential for local Spanish-language print media to challenge the negative semiotic representation of Latin@s in the USA while pointing to the need for future research of minoritized media using the social semiotics framework.  相似文献

Abstract: Differentiation of 21 glitter lip‐glosses from seven manufacturers was attempted by pyrolysis gas chromatography/mass spectroscopy. Samples were pyrolyzed on a ribbon probe at 800°C for 20 sec and analyzed with an Agilent® 6890N Network GC System and Agilent® 5973 Network Mass Selective Detector with MSD Productivity ChemStation® Data Analysis software. The total ion chromatograms obtained were examined and differences in the presence or absence of certain chromatographic peaks corresponding to certain pyrolysis products (e.g., styrene, cyclohexane) noted. In cases where the total ion chromatograms between lip‐glosses were similar, select ion profiling was performed. Of the 21 lip‐glosses, 15 were differentiated by either the total ion chromatograms alone or through select ion profiling. Considering that lip‐glosses are typically worn by young women (who are disproportionately victims of sexual assault), this study offers the potential of being able to provide investigative leads in sexual assault investigations with evidentiary samples of this kind.  相似文献

ABSTRACT

While there is increasing interest in gender and sex issues in the medical field, most research in medicine can still be defined as operating with a binary of sex/gender. Epigenetics presents a marked challenge to such binaries as it operates across many tightly held boundaries, blurring the lines between the biological and social. Feminist scholars are paying attention to this new field and reconsidering relationships between the politics of matter, biologies and the social in new ways. The aim of this article is to investigate how theoretical insights from material feminism might enhance epigenetic research. Rather than repeat important critical arguments that point to the dangers of reductionism and biological essentialism, we make a case for examining the ways that material feminism can engage with epigenetic research by broadening ideas of reproduction (beyond in-utero effects) to relational and political views of gender and sex within a materialist framework. In conclusion, we suggest that a focus on material-discursive co-formations has the potential to contribute to an established body of feminist theory and science work; increasing awareness of the intra-action of gender and sex in relation to exposures, and increasing political leverage in supporting health-enhancing environments.  相似文献
