In addition to money or other compensation, other motives for selling sex may be important in a welfare country such as Sweden. The aim of this study was to carry out an exploratory investigation of adolescents’ motives for selling sex in a population-based survey in Sweden. A total of 5839 adolescents from the third year of Swedish high school, mean age 18.0 years, participated in the study. The response rate was 59.7% and 51 students (0.9%) reported having sold sex. Exploratory factor analysis and hierarchical cluster analysis were used to identify groups of adolescents according to underlying motives for selling sex. Further analyses were carried out for characteristics of selling sex and risk factors. Three groups of adolescents were categorized according to their motives for selling sex: Adolescents reporting; 1) Emotional reasons, being at a greater risk of sexual abuse, using sex as a means of self-injury and having a non-heterosexual orientation. 2) Material but no Emotional reasons, who more often receive money as compensation and selling sex to a person over 25 years of age, and 3) Pleasure or no underlying motive for selling sex reported, who were mostly heterosexual males selling sex to a person under 25 years of age, the buyer was not known from the Internet, the reward was seldom money and this group was less exposed to penetrative sexual abuse or using sex as a means of self-injury. In conclusion, adolescents selling sex are a heterogeneous group in regard to underlying motives.  相似文献

ABSTRACT

This forum brings together food, (in)security, and communication. The authors participating in this forum center communication as both process and tool for understanding, mitigating, and making meaning of food (in)security. The nine authors together discuss the role of communication in food (in)security, the central challenges for scholars and practitioners working on food (in)security, and the creative possibilities and impacts influencing the future of food (in)security. The forum produces a call for applied scholars to re-imagine communication frameworks in order to make meaningful differences in their communities.  相似文献

Metaphor and Totem: Exploring and evaluating prior experiential learning   总被引:3,自引:3,他引:0  
The evaluation and recognition of prior experiential learning is now well established. A significant issue in such evaluations has been the centrality of the learner and his/her empowerment in the educational process. However, most models of evaluation require equivalency between the unique experiences of the subject and existing course analogues. In these models evaluation is based on metaphor, on finding varying degrees of similarity between the experience being assessed and currently existing academic structures. The present paper calls for a richer perspective to be taken in assessing prior experiential learning with particular interest being seen in the notion of totemism as characterised by anthropologist Claude Levi-Strauss. A replacement of metaphor by totemism may restore power, ownership and centrality of the experience to the candidate for assessment, while allowing evaluators an opportunity to engage in a novel but authentic articulation of the underlying academic equivalency of the experience.  相似文献

Within recent years scholars in both sociology of education and curriculum studies have explored what it is about the school that reproduces class, race and gender relations that maintain an unequal social structure. While it has long been recognized that school outcomes differ along these lines, the role that the school plays in creating differential outcomes and forms of consciousness that sustain fundamental inequalities and antagonisms has been largely ignored. This is as much true for scholars like Bowles and Gintis as it is for earlier functionalists.

This article begins to fill this void by focusing on the relationship between the ‘hidden curriculum’ and student culture. Data presented here were gathered as part of a larger study on the ‘lived culture’ of lower class black students in a community college (which I call Urban College) located in a large northeastern city in the United States. I argue that, rather than ‘determine’ student culture in any simple sense, the hidden curriculum and student culture emerge in relation to one another. Each creates aspects of the other and neither can be discussed or analyzed separately. The way in which elements of the hidden curriculum combine in a concrete culture to produce aspects of student consciousness is also discussed.  相似文献

According to bystander theory, factors such as the community environment, collective efficacy, and history of adverse childhood experiences could be related to likelihood of reporting or intervening against maltreatment. An online survey was conducted with 946 general population Californians obtained through mixed-mode random probability and quota-based recruitment methods. Using an experimental vignette design, participants were randomly assigned to two scenarios: a) potential child abuse occurring in their neighborhood; b) potential child abuse in an unfamiliar neighborhood. Weighted multivariate logistic regression models assessed relationships between the vignette condition, collective efficacy, appraisal of the behavior, and likelihood of reporting or intervening. The results suggested that perceiving the vignette as occurring in your own neighborhood was associated with lower odds of viewing the behavior as appropriate and considering it abusive. Higher collective efficacy scores were associated with lower odds of viewing the incident as inappropriate but higher odds of personally intervening. Adverse childhood experiences were positively related to reporting the incident to child protective services and intervening. Bystanders may be more likely to give parents in their own neighborhood "the benefit of the doubt" by viewing their abusive behaviors as less severe, potentially leading to underreporting. Neighborhood collective efficacy might increase willingness to personally intervene, but not contact systems such as child protective services or police, suggesting that enhanced trust in communities does not extend to these institutions. Our findings have implications for neighborhood and education interventions to enhance understanding of and willingness to intervene on behalf of children.  相似文献

Understanding the language of information literacy is necessary for the effective use of library resources. The results of a recent study indicate that undergraduate students lack such an understanding, and the authors recommend that librarians, working with faculty, reassess information literacy terms. This article examines what is involved in reassessing these terms by drawing on several ideas from the philosophy of language, which provides a foundation for grasping the semantic challenges librarians face in educating users. Any reassessment of information literacy terms should recognize their ordinary and specialized use and aim for the holistic expression of core concepts, however complex they may be.  相似文献

Air pollution is a critical environmental problem that has spurred great public concern in China. This study examines how issue salience, environmental value, risk perception, and affective response influence information seeking, objective knowledge, and policy support related to this issue. The recent release of a controversial environmental documentary on Chinese social media, Under the Dome, also prompted us to explore the impact of exposure to this documentary on Chinese social media users’ information seeking and policy support related to air pollution. Results showed that risk perception and negative affect influenced information seeking and policy support both directly and indirectly. Also, exposure to the documentary moderated the effects of key variables on information seeking and policy support. However, contrary to our expectations, no significant relationship was found between information seeking and objective knowledge. Theoretical and practical implications of these findings were discussed.  相似文献
