Time spent on social media and making online comparisons with others may influence users’ mental health. This study examined links between parental control over the time their child spends on social media, preadolescents’ time spent browsing social media, preadolescents’ appearance comparisons on social media, and preadolescents’ appearance satisfaction, depressive symptoms, and life satisfaction. Preadolescent social media users (N?=?284, 49.1% female; aged 10–12) and one of their parents completed online surveys. Preadolescents, whose parents reported greater control over their child’s time on social media, reported better mental health. This relationship was mediated by preadolescents spending less time browsing and making fewer appearance comparisons on social media. Parental control over time spent on social media may be associated with benefits for mental health among preadolescents.  相似文献

The present study provides a comparative analysis of sexual-minority and heterosexual emerging adult women’s experiences seeking support for sexual issues from parents and friends. Participants included 229 college women (88 sexual-minority women; 141 heterosexual women), ranging from 18 to 25 years of age, who provided written responses to an inquiry about a time they went to friends and parents for support for a issue related to their sexuality. Responses indicated that the majority of participants had sought support from either a parent or a friend and that mothers and female friends were more likely involved than fathers or male friends, respectively. Sexual issues that participants reported discussing with parents and friends were inductively grouped into five categories: dating and romantic relationships, sexual behavior, sexual health, identity negotiation, and discrimination and violence. Issues that were discussed differed based on sexual orientation identity and the source of support (parent or friend); they did not differ by age. Participants generally perceived parents and friends’ responses as helpful, though sexual-minority participants perceived both parents and friends’ responses as less helpful than did heterosexual participants. Overall, results suggest both similarities and differences between sexual-minority and heterosexual young women’s experiences seeking support for sexual issues from parents and friends.  相似文献

This article analyzes congressional activism during an international crisis. Using the 1994 Rwandan genocide as a case, this study explores executive–congressional relations during a time when immediate policy responses are needed. A content analysis of policy statements made during committees, on the House floor, and on the Senate floor is used to investigate the specific policy ideas proposed by members of Congress. The models presented pay particular attention to the actions of Congressional Black Caucus (CBC) members, in relation to other more common predictors of congressional activism. In addition to the results for CBC members, other conclusions indicate that foreign policy leaders in Congress are international affairs policy experts without serious concerns of being defeated in their next election.  相似文献

ABSTRACT

Internal marketing and internal communication collectively strive to build relationships with, empower, and motivate employees to foster an organisational culture of support for organisational goals and objectives to be met and organisational success achieved. Electronic newsletters support internal marketing and internal communication endeavours as they serve the purpose of transferring organisational information to employees. E-newsletters can be tested to determine whether employees willingly utilise them for their intended purposes. By means of a quantitative research approach, utilising regression to analyse the empirical data, a study was conducted to determine employees’ acceptance of e-newsletters. This was conducted by means of an adapted technology acceptance model (TAM), and a self-administered e-mail survey was disseminated to employees of a higher education institution. Based on the research results, employees perceive TAM differently to what is put forward in literature, which results in the acceptance of e-newsletters for the purpose of transferring organisational information. Results show that respondents perceived two of the factors of TAM as one factor. In addition, the results provide insight into how academic employees perceive e-newsletters and what practical changes can be made to e-newsletters in order to cater to employees’ preferences.  相似文献

Substance use often begins earlier among American Indians compared to the rest of the United States, a troubling reality that puts Native youth at risk for escalating and problematic use. We need to understand more fully patterns of emergent substance use among young American Indian adolescents, risk factors associated with escalating use trajectories, and protective factors that can be parlayed into robust prevention strategies. We used growth mixture modeling with longitudinal data from middle-school students on a Northern Plains reservation (Wave 1 N = 381, M age at baseline = 12.77, 45.6 % female) to identify subgroups exhibiting different trajectories of cigarette, alcohol, and marijuana use. We explored how both risk (e.g., exposure to stressful events, deviant peers) and protective (e.g., positive parent–child relationships, cultural identity) factors were related to these trajectories. For all substances, most youth showed trajectories characterized by low rates of substance use (nonuser classes), but many also showed patterns characterized by high and/or escalating use. Across substances, exposure to stress, early puberty, and deviant peer relationships were associated with the more problematic patterns, while strong relationships with parents and prosocial peers were associated with nonuser classes. Our measures of emergent cultural identity were generally unrelated to substance use trajectory classes among these young adolescents. The findings point to the importance of early substance use prevention programs for American Indian youth that attenuate the impact of exposure to stressful events, redirect peer relationships, and foster positive parent influences. They also point to the need to explore more fully how cultural influences can be captured.  相似文献

We have carried out experiments to investigate the aging of latent fingerprints deposited on black PVC over a period of 4–15 weeks. A thumbprint was used in each case and before deposition of the print the donor rubbed their thumb around their nose to add sebaceous deposits. We have studied the effect of heat, light, and moisture and we find that moisture is the most significant factor in the degradation of the latent print. We have attempted to enhance these latent prints by dusting with valine powder or powders composed of valine mixed with gold or red fluorescent commercial fingerprint powders. To make a direct comparison between “treated” and “untreated” prints, the prints were cut in half with one‐half being “treated” and one‐half not. Our studies show the best results being obtained when powders of valine and red fluorescent powders are applied prior to cyanoacrylate fuming.  相似文献

Mortgage servicing has garnered increased attention since the foreclosure crisis. As the interface between borrowers and investors, servicers make the decision to either grant a loan modification or to foreclose. This study examines servicer loan modification practices for a national sample of delinquent subprime loans, and assesses the extent to which those practices are associated with foreclosures. The research reveals significant differences across servicers in loan cure rates, which are related to servicers’ propensity to offer loan modifications and to the level of relief offered to borrowers. The observed differences across servicers and the implications of this heterogeneity for foreclosure prevention underscore the importance of additional data, research, and policies that can increase the uniformity and transparency of servicing practices.  相似文献

The detection of insider threats is one area of ongoing work at the CERT® Insider Threat Center. This paper addresses the legal landscape surrounding employee privacy in the workplace. While this broad area implicates many different types of law, this paper focuses on some current issues that employers may want to be aware of when implementing policies and practices to mitigate the insider threat, including monitoring of current employees. Electronic, physical and other methods of monitoring are discussed, which can reveal insider threat indicators. Relevant federal and state laws are also discussed.1  相似文献
