Objectives: The conditions under which adolescents should have access to birth control has been debated by U.S. policy makers and health officials for some time. Given the variability and fluidity of law and policy in this area and the high stakes described by advocates for and against access, identifying predictors of electorate opinion is important. Methods: This study utilized national panel data gathered in 2008 (T1) and 2010 (T2) to examine associations between U.S. adults' pornography consumption and attitudes toward adolescents' access to birth control. Results: Consistent with a social learning perspective on media, pornography consumption at T1 was associated with more positive attitudes toward adolescents' access to birth control at T2, even after accounting for T1 birth control attitudes and multiple potential third-variables. Consistent with Wright's (2011 Wright, P. J. (2011). Mass media effects on youth sexual behavior: Assessing the claim for causality. Communication Yearbook, 35, 343386. [Google Scholar]) acquisition, activation, application model (3AM) of media sexual socialization, this association was stronger for more morally individualistic adults. Contrary to a selective exposure perspective on media, birth control attitudes at T1 did not predict pornography consumption at T2. Conclusions: These findings have implications for the prediction of birth control attitudes specifically and the socializing influence of pornography more generally.  相似文献

Job quality of young adults in the USA has been eroding since the Great Recession of 2007. The intensity of job search activities are a well-established predictor of employment, yet little is known whether job search intensity is associated with the quality of subsequent secured employment. This study examined the 2013 sample of the National Longitudinal Survey of Youth (NLSY) (N?=?1566), which follows a sample of American youth born between 1980 and 1984 and contains reliable measures of job search activities and job quality. Multivariate regression models examined whether job search activities were associated with pay, paid vacation days, full time job status, regular work schedule, and availability of a union contract, controlling for demographic factors. The results demonstrated that the number of job search activities completed was positively associated with multiple positive employment-related outcomes. Programs to assist individuals in the job search process may benefit from these results when offering strategies for successfully securing employment of a higher quality that may offer increased quality of life.  相似文献

This paper reports on an effort to develop an Internet well-being measure for possible use by government agencies and industry associations that are directly involved with the promulgation of the Internet. Such measures can help officials gauge the social health of those Internet-related industries and institutional sectors, which in turn can guide the development of policies to enhance the quality-of-life impact of the Internet. The Internet well-being measure is based on the theoretical notion that the perception of the overall impact of the Internet on users of the Internet is determined by their perceptions of the impact of the Internet in their life domains such as consumer life, work life, leisure life, social life, community life, sensual life, among others. In turn, the perception of impact of the Internet in a given life domain (e.g., consumer life, work life) is determined by perceptions of benefits and costs of the Internet within that domain. We conducted a focus group to identify all the perceived benefits and costs within salient life domains of college students. We also conducted a thorough literature search to identify studies that examined the quality-of-life impact of the Internet in a variety of life domains. We then tested the nomological validity of the measure through two surveys at two major universities (one in the USA and the other in Korea). The statistical analysis allowed us to identify those measurement items that are most predictive, and therefore considered as nomologically valid. Policy implications of the study are discussed along with future research avenues.  相似文献

This study investigates the role of leadership in facilitating strategic communication management and effective public relations practice by proposing a set of dimensions measuring corporate communication executives’ perceptions on leadership. A measurement methodology was applied and suggested to facilitate empirical investigation. Data from two groups of senior corporate communicators and public relations executives (N = 384) nationwide were used to assess the validity and reliability of proposed leadership dimensions that contribute to effective communication management. Results from both groups demonstrated strong support for the proposed higher-order measurement model. The analysis suggested that 6 major dimensions (self-dynamics, team collaboration, ethical orientation, relationship building, strategic decision making capability, and communication knowledge management capability) are crucial for communication executives to expand their influence in the institutional context and generate desired communication outcomes. The findings offer insights on both leadership and corporate communications that may account for significant nonfinancial indictors of organizational effectiveness.  相似文献

The potential use of strategic conflict management ( Wilcox and Cameron, 2006; Cameron, Wilcox, Reber and Shin ( in press) as a health advocacy tool in US African-American and mainstream newspapers, arguing that escalation of conflict can increase effectiveness of health-related news releases. For health communicators focusing on at-risk populations with poor health outcomes, such goals would include increased awareness of health problems and solutions, along with increased motivation arising from indignation over health disparities. Content analysis of 1,197 stories in 24 Black and 12 mainstream newspapers showed that more conflict factors were present in Black vs. mainstream newspapers, suggesting a way to strategically place health messages in news releases disseminated to newspapers that motivate at-risk publics to better health. The findings suggest that conflict factors such as racial disparity data regarding health issues may enhance media advocacy.  相似文献

For a loss distribution belonging to a location–scale family, Fμ,σFμ,σ, the risk measures, Value-at-Risk and Expected Shortfall are linear functions of the parameters: μ+τσμ+τσ where ττ is the corresponding risk measure of the mean-zero and unit-variance member of the family. For each risk measure, we consider a natural estimator by replacing the unknown parameters μμ and σσ by the sample mean and (bias corrected) sample standard deviation, respectively. The large-sample parametric confidence intervals for the risk measures are derived, relying on the asymptotic joint distribution of the sample mean and sample standard deviation. Simulation studies with the Normal, Laplace and Gumbel families illustrate that the derived asymptotic confidence intervals for Value-at-Risk and Expected Shortfall outperform those of Bahadur (1966) and Brazauskas et al. (2008), respectively. The method can also be effectively applied to Log-location-scale families whose supports are positive reals; an illustrative example is given in the area of financial credit risk.  相似文献

With its rapid industrial transformation over the last two decades, Korea has experienced a massive population shift from rural to urban areas. In particular, population concentration together with the concentration of economic and political power in the primate city of Seoul created spatial imbalances and a host of urban problems which are not uncommon to many developing nations. In response to these persisting imbalances and problems, the government of Korea has implemented various programs and measures since 1970. Korea's experiment with population redistribution, although it may not be easily replicated in other countries, provides a rare example with which we can examine some of the major issues involved in population distribution policies. The paper reviews Korean policies and programs for population redistribution, assesses their effects in redressing the three major spatial imbalances - between urban and rural, between regions, and between cities of different sizes - and draws lessons for policy formation in Korea as well as in other countries which are considering such a policy.  相似文献
