Abstract Objective: Sexually transmitted infections and the human immunodeficiency virus incidence rates remain high among college-aged individuals. This study examined the validity and reliability of the Multi-Factor Attitude toward Condoms Scale (MFACS). Participants: Participants were recruited from a large midwestern university during February and March 2009. Methods: Data were collected using in-class data collection with a test–retest design from undergraduate courses. A total of 442 surveys were collected during initial testing and 421 during retesting. Results: Reliability assessments indicated a sufficient Cronbach's alpha for the total scale (α = .805) and each subscale: affective (α = .790), perceived effectiveness (α = .795), and manageability (α = .751). Further analyses provide evidence of construct validity. Conclusions: The study reaffirmed the psychometric properties of the MFACS among a sample of college students. The MFACS provides a contemporary way to examine condom attitudes as sexual health research is moving beyond only disease prevention efforts. 相似文献

This paper presents a new model incorporating features of developing country agriculture likely to shape the welfare outcomes of alternative agricultural policies. The model features heterogeneous households linked through markets in a rural economy-wide structure, with endogenous market participation for farmers facing transactions costs. We use it to simulate the impacts on rural welfare of market price supports, production subsidies, input subsidies, and the removal of transaction costs. Applications to six countries demonstrate the diversity of potential impacts, exhibit some systemic differences compared with impacts in developed countries, and identify specific circumstances under which market interventions may be only slightly less efficient than direct payments at transferring incomes to rural households. 相似文献

This article addresses the widening gap between costs and revenues for many arts nonprofits; it examines the most common explanations for the problem, categorizes possible solutions, and suggests practical strategies for implementation. This study suggests that a critical difference exists between large and small arts firms, which in turn implies a different set of strategies for each. Whereas large organizations do well to leverage technological innovations, diversify product lines, and expand audiences through educational outreach, smaller organizations tend to see greater returns from efforts to expand their philanthropic base. 相似文献

AbstractThe digital divide affects many nations of the developing world. The term encompasses inadequate funding, a lack of necessary computer and Internet skills, and a lack of English-language proficiency that hinder expansion and use of digital information resources. Visionary individuals and organizations can assist these countries with their information needs. Aggregated full-text databases serve as a prominent tool in closing the digital divide because they provide important research resources. Participating organizations must demonstrate the value of these resources to users and supply essential training to ensure success with electronic resource initiatives. 相似文献

This study used longitudinal data to elucidate how trajectories of negative parenting across adolescence are associated with young adult health risk behaviors (HRBs) by testing difficulties with emotion regulation and externalizing symptomatology as sequential underlying mediators. The sample included 167 adolescents (53% males, Mage = 14 at Time 1 and Mage = 18 at Time 5) who were assessed five times. Adolescents self-reported on negative parenting, emotion regulation, externalizing symptomatology, and engagement in HRBs. Results suggest that increasingly negative parenting across adolescence has adverse consequences for emotion regulation development and in turn, externalizing symptomatology, which confers risk for young adult HRBs. Results offer insights towards mechanisms for prevention and intervention and public health policy aimed at reducing the prevalence and consequences of engagement in HRBs. 相似文献
