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

BackgroundChild sexual abuse (CSA) is a problem with severe consequences for victimized children. A variety of interventions have been developed and implemented over the last decades to prevent CSA. However, most of them have not been systematically evaluated to determine their effectiveness. The IGEL program is a school-based intervention to prevent CSA in third-grade primary school children in Germany.MethodsThis study was conducted using a quasi-experimental design, in which almost 300 children and their parents from eight intervention and four control schools were surveyed three times (pretest, posttest, 3 months later). In order to measure outcomes, a questionnaire was developed based on validated instruments to assess the knowledge, courses of action and self-protective skills of the children. Furthermore, increased anxiety and generalized touch aversion were examined as potentially harmful side effects of the program.ResultsThe results clearly demonstrate increased CSA-related knowledge and courses of action in children from the intervention group compared to the control children. These effects were medium-sized and sustained for at least three months after the last session. No meaningful negative side effects were detected in the evaluation for either the children or parents.ConclusionThe outcome evaluation indicates that the IGEL program is an effective intervention in terms of knowledge about CSA and known courses of action, and may therefore contribute to the prevention of CSA in primary schools. Despite this positive core finding of the intermediate outcomes, some adaptations of the program to children with different cultural backgrounds were made prior to further dissemination. 相似文献

Play is a behavioral phenomenon most commonly observed in the young of both solitary and social species. Documentation of play in cetaceans varies across species and settings. Cetacean play behavioral repertoires include a broad range of actions, such as the manipulation of diverse objects, blowing bubbles, chasing conspecifics, and swimming in spirals through the water. As is common in research on animal play, cetacean play has been grouped into categories by its form, including locomotor play, object play, and different variations of social play, such as affiliative games, play fighting, and socio-sexual play. Research has primarily focused on recording the topography of cetacean play and the demographics of the individuals engaging in play. However, these classifications are insufficient to address the possible developmental and societal functions of cetacean play behaviors, or the mechanisms with which play behaviors are spread between conspecifics and acquired by young members of cetacean populations. This article applies several developmental and social learning theories in order to organize current knowledge and guide future research. 相似文献

Observations of 23 free-ranging rhesus monkey infants on Cayo Santiago, Puerto Rico, indicated that mothers' first postpartum estrous periods were marked by large increases in the amount of time infants were separated from their mothers, by disturbances in mother-infant relationships, and by increases in infant distress behavior. When their mothers resumed mating, most infants showed signs of agitation; a few briefly showed indications of depression. Male infants responded to their mothers' resumption of mating by playing more, whereas females engaged in less play and more allogrooming. The results suggest ( a ) that basic parallels exist between the behavioral responses of rhesus infants to their mothers' resumption of mating in the field and to forcible separation from their mothers in captivity and ( b ) that early separation experiences may play a role in the normal development or manifestation of sex differences in behavior. 相似文献

Abstract In the field of teacher education, the disconnect between university-based coursework and practical field experiences has long been a concern. To make teacher preparation coursework more meaningful, some programs partner with P-12 schools to offer site-based courses. Although situated learning for novices in practice-based professions makes sense, more research is needed to determine if, how, and why site-based courses in particular may be beneficial for teacher candidates’ (TCs) learning. In this study, we used surveys and interviews with TCs, who had taken the same site-based literacy methods course, to identify which aspects of the course they found most facilitative of connections between the course content and the field. Our findings suggest working with children in classrooms, course instructors’ involvement at the school, and opportunities to discuss and reflect upon their experiences immediately after they had been in the field were the primary features of a site-based course TCs found valuable. 相似文献

This study explored transactional associations among visuomotor integration, attention, fine motor coordination, and mathematics skills in a diverse sample of one hundred thirty‐five 5‐year‐olds (kindergarteners) and one hundred nineteen 6‐year‐olds (first graders) in the United States who were followed over the course of 2 school years. Associations were dynamic, with more reciprocal transactions occurring in kindergarten than in the later grades. Specifically, visuomotor integration and mathematics exhibited ongoing reciprocity in kindergarten and first grade, attention contributed to mathematics in kindergarten and first grade, mathematics contributed to attention across the kindergarten year only, and fine motor coordination contributed to mathematics indirectly, through visuomotor integration, across kindergarten and first grade. Implications of examining the hierarchical interrelations among processes underlying the development of children's mathematics skills are discussed. 相似文献

This paper explores whether high-school sports are functional and accessible activities to keep students from school disciplinary behaviors. For this purpose, we included students racial and linguistic status, socioeconomic status, sex, and prior academic performance with the school’s proportion of free-lunch recipients and minorities, to understand how sport participation affects students of diverse groups. Additionally, the study implemented a multilevel mediation modeling to the Education Longitudinal Study (ELS) data and assessed student dropouts with sequential mediators of sport participation, school misbehavior, and suspension. The findings of the study largely revealed that White students participated in sports more than Black, Hispanic, and Asian. Likewise, students who speak English as the primary language and male students participated in sports more than their counterparts. White sport participants displayed fewer incidents of suspension than White non-sport participants. Black, Hispanic, and White sport participants had lower dropout incidents than their non-sport-participating counterparts. 相似文献

Audiogenic seizures in mice: Asymmetries of the preconvulsive running pattern and subsequent seizure
Asymmetries in the progression of unilaterally and bilaterally induced audiogenic seizures were examined in DBA/2J and SJL/J mice. Both strains were found to exhibit consistent asymmetries in direction(s) of running as well as in the side of fall during a convulsion. This correspondence suggests that the bursts of running are an integral part of an audiogenic seizure. The incorporation of information on asymmetries of the locomotor prelude in future studies should prove valuable for understanding the physiological mechanisms of audiogenic seizure. 相似文献

This study examines the degree of association between students’ STEM occupational expectations and between-country differences in public attitudes toward science and technology (S&T). This study focuses on public attitudes among two different populations: students and adults. Three-level Hierarchical Generalised Linear Models are employed to analyse large-scale international data from the Programme for International Student Assessment (PISA). Results reveal that public attitudes toward S&T are positively associated with students’ expectations around pursuing STEM careers. Further analyses reveal that the positive association between public attitudes toward S&T and STEM career expectations remains consistent across gender, but that this association varies across performance levels. The positive association between public attitudes toward S&T and STEM career expectations is stronger for low achievers in science than for high achievers. These results advance the scholarly understanding of the ways in which social factors may be associated with students’ choices in pursuing STEM occupations. 相似文献
