This study used a person-centered approach to examine whether different developmental trajectories of boys’ and girls’ use of sexually explicit Internet material (SEIM) exist, which factors predict these trajectories, and whether sexual behavior develops differently for adolescents in these trajectories. A combination of latent class growth analysis on SEIM use and latent growth curve analysis on sexual behavior was used on four-wave longitudinal data of 787 eighth through tenth grade Dutch adolescents. Among boys, four SEIM use trajectories were identified, which were labeled Nonuse/Infrequent Use, Strongly Increasing Use, Occasional Use, and Decreasing Use. Among girls, a large Stable Nonuse/Infrequent Use and smaller Strongly Increasing Use and Stable Occasional Use trajectories were distinguished. Higher initial levels and/or stronger increases in SEIM use were predicted by demographic, social contextual, personal, and media use characteristics, including a stronger sexual interest, a higher degree of perceived realism regarding sexualized Internet content, and more permissive sexual attitudes. Moreover, initial levels of and, to some extent, developmental changes in sexual behavior varied for boys and girls in the different SEIM use trajectories. Whereas some adolescents showed concurrent low levels, or parallel strong increases in SEIM use and sexual behavior, a subgroup of boys decreased their SEIM use while increasing their sexual behavior.  相似文献

Sexual communication is a principal means of transmitting sexual values, beliefs, expectations, and knowledge from parents to children. Although this area has received considerable research attention, more studies with representative samples are needed to assure that findings are reflective of populations of interest. A nationally representative sample of parent–adolescent dyads (N = 2,965; mean adolescent age = 13.8 years) in the Netherlands was employed to examine the frequency of parent–adolescent sexual communication and its association with adolescent sexual behaviors (defined as sexual initiation, condom use, and contraceptive pill use). Nine communication topics in the areas of anatomy, relationships and rights, and protection and contraception were examined. In all, 75%of parents reported having discussed at least one topic multiple times with their adolescents. Romantic relationships were discussed most frequently. Hierarchical logistic regression analyses indicated that parent–adolescent sexual communication on protection and contraception was positively associated with adolescent sexual initiation and contraceptive pill use but not condom use. This may reflect that adolescents, when they become sexually active, are more likely to discuss sexuality with their parents. Findings are interpreted within the context of Dutch culture, which is generally accepting of adolescent sexuality and characterized by open sexual communication.  相似文献

Research has increasingly noted that gay male adults are more at risk for developing body image dissatisfaction than other male populations. Body image issues warrant attention, particularly since they have been connected to the development of disordered eating patterns. Studies have often traced gay male body dissatisfaction to various sociocultural elements and phenomena, particularly the media. In fact, various media genres have been implicated as being instrumental in propagating idealized male physiques, which in turn may negatively influence observers. Using objectification theory, this paper aims to review the process by which media imagery are internalized by some gay men and how such internalizations harmfully impact their body image. The clinical implications and treatment of body dissatisfaction will be reviewed in terms of social work practice with gay male populations.  相似文献

Objectives: Do short, online educational messages about the human papillomavirus (HPV) influence younger and older men who have sex with men (MSM) differently? Second, what are the HPV knowledge levels and risk perceptions of Southern MSM living outside of major metropolitan areas? Methods: This study draws on participants who completed an anonymous online survey asking about their knowledge, risk assessment, and vaccine acceptance regarding HPV. Results: Knowledge about HPV was low among the MSM in this study. After reading a one-page information intervention, vaccine acceptability increased by a statistically significant amount among both a Younger and Older cohort but risk perception only increased among the younger respondents. Single men regardless of age cohort reported sharper increases in perceived risk after the intervention, but relationship status did not produce significant differences in vaccine acceptability. Conclusion: Online, brief interventions may be effective means of increasing motivation to vaccinate among Southern MSM.  相似文献

We examine financial reporting lags among a large sample of Belgian non-profit organizations (NPOs). Doing so, we add to the literature on financial reporting and accountability in the non-profit sector. Next to drivers of the financial reporting lag that have been identified in prior studies based on private firms (e.g., delaying the disclosure of bad news), we find that the way of funding the NPO (i.e., reliance upon donations and/or grants) and its specific area of activity are significantly related to the financial reporting lag. Our results also suggest that important changes in accounting regulation significantly delay the financial reporting process. Importantly, we note that 17.2 % of the sample organizations do not file their financial statements within the legal time span.  相似文献

By means of an example it is shown how eigenvalues and eigenvectors of variance components models can be obtained straightforwardly when balanced data are available. Simple asymptotically efficient estimators of the variance components are presented.  相似文献

From the literature three types of predictors for factor scores are available. These are characterized by the constraints: linear, linear conditionally unbiased, and linear correlation preserving. Each of these constraints generates a class of predictors. Best predictors are defined in terms of Lowner's partial matrix order applied to matrices of mean square error of prediction. It is shown that within the first two classes a best predictor exists and that it does not exist in the third.  相似文献

This research reexamines the meaning of occupational prestige scores from the social psychological perspective of identity theory. Using comparable data for Canada and the United States, it analyzes the degree to which the education and income levels of occupations influence occupational prestige judgements by evoking affective associations (feelings about the goodness, powerfulness, and liveliness of occupational identities), as well as the extent to which these social sentiments are independent determinants of prestige. There has been a longstanding controversy about the normative content of occupational prestige scores. We find that moral worthiness (as measured by the Evaluation dimension of the semantic differential) is a determinant of the prestige of occupations with low and middle but not high levels of education and income. We also find that the impact of education on prestige scores is direct and cognitive, while a considerable proportion of the total effect of income is processed through feelings about the potency of occupations. The results for the two countries are very similar. One exception is that moral worthiness is a more important determinant of prestige in the United States than in Canada. We connect this finding to the literature comparing value differences between the two countries.  相似文献

For over 20 years, family therapist Karl Tomm has been engaging families and couples with a therapeutic intervention he calls Internalized Other Interviewing (IOI). The IOI (cf. Emmerson‐Whyte, 2010; Hurley, 2006) entails interviewing clients, from the personal experiences of partners and family members as an internalized other. The IOI is based on the idea that through dialogues over time, one can internalize a sense of one's conversational partner responsiveness in reliably anticipated ways. Anyone who has thought in a conversation with a family member or partner, “Oh there s/he goes again,” or anticipates next words before they leave the other's mouth, has a sense of what we are calling an internalized other. For Tomm, the internalized anticipations partners and family members may have offers entry points into new dialogues with therapeutic potential—particularly, when their actual dialogues get stuck in dispreferred patterns.  相似文献
