Information about the pornography-viewing habits of urban, low-income youth of color in the United States is lacking. This study was designed to answer the following using a sample of 16- to 18-year-old urban-residing, low-income Black or Hispanic youth: (1) What types of pornography do youth report watching; where and for what purpose? (2) Do youth feel that pornography exposure has an impact on their own sexual behaviors? and (3) How do parents react to their pornography use? The following themes emerged from interviews with 23 youth: (1) Youth primarily reported watching pornography that featured one-on-one sexual intercourse but also reported having seen extreme pornography (e.g., public humiliation, incest); (2) youth reported watching pornography on home computers or smartphones, and that pornography was frequently watched in school; (3) youth reported watching for entertainment, for sexual stimulation, instructional purposes, and to alleviate boredom; many copied what they saw in pornography during their own sexual encounters; (4) pressure to make or to imitate pornography was an element of some unhealthy dating relationships; and (5) parents were generally described as unsupportive of youth's use of pornography but underequipped to discuss it. Approximately one-fifth expressed a preference for pornography featuring actors of their same race/ethnicity.  相似文献

ABSTRACT. Objectives: This study examined the risk for engaging in high-risk sexual behavior associated with substance use in a sample of U.S. adolescents. Methods: The sample (N = 15,425) was obtained via the Youth Risk Behavior Surveillance System, a survey of public high school students. Results: Substance use was associated with sexual risk behaviors, with odds ratios being greatest for adolescents who used cigarettes and illicit substances, as well as those who engaged in injection drug use. Conclusions: Results highlight the need for prevention and intervention programs targeting sexual risk behaviors in substance-using adolescents as a means to decrease the spread of sexually transmitted infections.  相似文献

Using structural equation modeling, the present study investigated relationships between neuroticism, coping strategies, and negative career thoughts within the context of attaining a positive career decision state. Results from the initial model, based on a sample of college students (119 women, 113 men; M = 20.3 years) enrolled in a career development course, revealed that coping strategies were not a significant contribution to the model. The final model, without coping strategies, showed that neuroticism had a significant indirect effect on career decision state through negative thinking and that the relationship between neuroticism and career decision state was also significant. Findings also indicate that in the presence of negative career thoughts, neuroticism becomes associated with a more positive career decision state. Practical implications include suggestions that counselors intervene on clients' negative career thoughts to potentially render their neurotic tendencies more productive in reaching a desired career decision state.  相似文献

In addition to outlining criteria for the approval of human subjects research, federal regulations provide guidance regarding local institutional review boards (IRB) membership. IRBs are mandated to include "at least one member whose primary concerns are in nonscientific areas" and "at least one member who is not otherwise affiliated with the institution." Often a single individual serves both of these roles simultaneously. Although there have been calls for increased representation of lay community members in IRBs, little is known regarding their experiences or their perceptions of human subject protections and the IRB process. Using an ethnographic interview approach, this study seeks to gain a perspective from non-affiliated, non-scientist (NA/NS) IRB members about the process in which they participated. Findings suggest a need for clarification regarding whom NA/NS IRB members represent. They also suggest that NA/NS IRB members' experiences could be improved by an increased show of respect from the IRB chair, other members, and staff; efforts to make participation more convenient for these volunteer members; and training tailored specifically to NA/NS members. Further research on this important and understudied topic is needed to determine best practice and policy recommendations.  相似文献

Discussions about the role of paid employment in high school students’ lives usually involve untested assumptions about historical trends in the frequency, intensity, and selective nature of students’ employment behaviors. Using several nationally representative data sources, we find few changes in rates of employment or hours worked per week among adolescents since 1940 or among students since 1980. We observe important changes in recent decades in racial/ethnic and gender differences in employment and intensive employment. Finally, we observe that the relationship between students’ intensive employment and high school completion has been stable and persistently significant since the late 1960s.

The study of emotions in the workplace is a vibrant area of research that has grown considerably over the last 25 years. This research has traveled far, but it has not run its course. This article maps the different paths that have been explored, beginning with Hochschild's classic work on emotional labor in the form of surface and deep acting, and charts new directions for future research. We start by reviewing the literature on emotional labor and emotion management in the workplace. Next, we discuss new theoretical developments in the sociology of emotions – interaction ritual chain theory, theories of identity and affect control, and theories about power, status, and exchange – and their potential utility for understanding emotions at work. Finally, we discuss new methodological directions that can be pursued in future research on emotions in work and organizational settings.  相似文献

Homelessness holds a longstanding place on the sociological research agenda, and has become particularly prominent in sociological literature since the 1980s. Recent literature reviews have summarized this research, but have only briefly considered the body of work focused on the experience of homelessness. I use this literature review to provide a more complete summary of this work on the daily lives, activities, subcultures, social relationships and networks, and social interactions of homeless individuals. I then explore variations in these experiences across important characteristics – such as gender, race and ethnicity, family status, and sexual orientation – as well as within three particular contexts that have been studied by sociologists: the streets, shelters and other service organizations, and social movements and collective action. I also consider how the homeless encounter and manage stigma and salvage the self. In addition to reviewing this literature, I consider how this work contributes to sociological understandings more broadly, and potential future research directions.  相似文献

The Gambling Passion Scale (GPS) is a recently developed research instrument for assessing individuals' passion for gambling. Because the psychometric properties of the GPS have only previously been examined in French Canadians, the aim of this study was to replicate previous psychometric findings in an English-speaking university sample. Participants (female: n = 58; male: n = 89) were drawn from a university campus based on self-reported experience with gambling indexed by scores on the South Oaks Gambling Screen (SOGS). The two-factor structure reported by Rousseau et al. (Journal of Gambling Studies, 18(1), pp. 45–66, 2002) was largely replicated in this sample, as were relationships between ‘obsessive passion’ and negative consequences stemming from gambling. These results support the validity of the GPS as a measure of gambling passion in English-speaking university gamblers and its potential to contribute to understanding problem gambling.  相似文献

Influence of seasonality and vegetation type on suburban microclimates   总被引:2,自引:0,他引:2  
Urbanization is responsible for some of the fastest rates of land-use change around the world, with important consequences for local, regional, and global climate. Vegetation, which represents a significant proportion of many urban and suburban landscapes, can modify climate by altering local exchanges of heat, water vapor, and CO2. To determine how distinct urban forest communities vary in their microclimate effects over time, we measured stand-level leaf area index, soil temperature, infrared surface temperature, and soil water content over a complete growing season at 29 sites representing the five most common vegetation types in a suburban neighborhood of Minneapolis–Saint Paul, Minnesota. We found that seasonal patterns of soil and surface temperatures were controlled more by differences in stand-level leaf area index and tree cover than by plant functional type. Across the growing season, sites with high leaf area index had soil temperatures that were 7°C lower and surface temperatures that were 6°C lower than sites with low leaf area index. Site differences in mid-season soil temperature and turfgrass ground cover were best explained by leaf area index, whereas differences in mid-season surface temperature were best explained by percent tree cover. The significant cooling effects of urban tree canopies on soil temperature imply that seasonal changes in leaf area index may also modulate CO2 efflux from urban soils, a highly temperature-dependent process, and that this should be considered in calculations of total CO2 efflux for urban carbon budgets. Field-based estimates of percent tree cover were found to better predict mid-season leaf area index than satellite-derived estimates and consequently offer an approach to scale up urban biophysical properties.  相似文献

Better models of culture and cognition may help researchers understand fertility and family formation. The authors examine cognition about fertility using an experimental survey design to investigate how fertility preferences of college women are affected by two prompts that bring to mind fertility‐relevant factors: career aspirations and financial limitations. The authors test the effects of these prompts on fertility preferences and ask how effects vary with respondent religiosity, an aspect of social identity related to fertility preferences. The authors find significant effects of treatment on fertility preferences when accounting for religiosity: Less religious women who considered their career aspirations or financial limitations reported smaller desired family size, but this effect was attenuated for more religious women. This study demonstrates how fertility preferences are shaped by decision contexts for some sociodemographic groups. The authors discuss how the findings support a social–cognitive model of fertility.  相似文献
