The main goal of this article is to provide empirical evidence that alcohol consumption reinforces the occurrence of mental illnesses even at early stages of life. We control probit estimations for unobserved heterogeneity and endogeneity. We have drawn a sample of 73,024 individuals from the Spanish National Survey on Drug Use in the School Population (2000, 2002, 2004). Our results confirm our theoretical hypothesis that alcohol consumption has a negative influence on youth state of health, but the magnitude of this influence is lower once we controlled for unobserved heterogeneity and endogeneity. Gender differences reveal that females are more likely to have been prescribed tranquilizers, and they are also more vulnerable to alcohol consumption than males are. As effective instruments to improve young people well-being, we suggest increasing the price of liquors and a greater parental control in how their children spend their available budget, and more important, in how they feel.  相似文献

In these times, when fame is available to almost anyone, it is worth being able to measure the extent and dimensions of a person's charisma. Most of the research on charisma to date is restricted to the area of leadership. In this article, however, charisma is generalized to take in all human beings and is conceptualized as a multi-dimensional cognitive-affective phenomenon. The article presents a pilot study aimed at providing an adequate operational definition of the construct as well as an initial tool for its measurement. A following literature review shows how authors have developed the concept of charisma and its initial operational dimensions for empirical research. A questionnaire is developed in three stages. The factor analyses applied in stages two and three point towards a six-factor solution (i.e. six dimensions of charisma). Further analysis reveals that the developed instrument is reliable and viable as well as applicable for future theoretical and practical work.  相似文献

This research project examined the individual and combined effectiveness of an HIV prevention workshop and a free condom distribution program in four high schools in Tijuana, Mexico. Adolescents (N = 320) completed baseline measures on sexual practices and theoretical correlates and participated in a two-part study. In Study 1, students were randomly assigned to an HIV prevention workshop or a control condition, with a 3-month follow-up assessment. Results indicate three significant workshop benefits regarding HIV transmission by altering sexual initiation, access to condoms, and traditional beliefs regarding condoms. In Study 2, we set up a condom distribution program at two of the participating schools, and students completed a 6-month follow-up assessment. Results indicate that exposure to the workshop followed by access to the condom distribution program yielded two beneficial results for reducing HIV transmission: moderating sexual initiation and increasing condom acquisition. Access to the condom distribution program alone had no effects on behavioral and psychosocial correlates of HIV transmission. We discuss implications of these results.  相似文献

Digital natives (also known as “Generation Y” and “Millennials”), a generation born during of after introduction of digital technologies, 1980s and after, have mixed preferences for media use in personal and professional lives. A study by Friedl and Tkalac Ver?i? (2011) showed that even though digital natives prefer digital media in their personal lives, this is not necessarily reflected in their business lives. This study addressing preferences of “traditional” vs. “the new media” in a university setting found an opposite result.  相似文献

In the fast moving software industry, projects have been increasingly developed by distributed teams, which are located in geographically remote offices and collaborate using information communication technologies. In such environments, project distribution presents specific challenges, as work in distributed teams increases project technical complexity, communication lines multiply and stakeholders’ interests may be divergent. Despite the importance and complexity of this type of problem, it seems that there is a lack of reports, in the literature, of systems that could support these decisions. This paper presents a real-world case study, where we developed a multi-criteria model for supporting the distributed team work allocation decision for a major global software company. It was developed with a group of software development project managers, using decision conferencing and multi-attribute value analysis. The model deals not only with software engineering attributes, but also “soft” and strategic issues, like team satisfaction and training opportunities. We also discuss some issues and challenges faced during this modelling process.  相似文献

Economics starts with the observation of widespread scarcity and the consequent need for choices about resource allocation. Common criteria for such choices are economy, effectiveness, efficiency and equity. This paper defines these criteria and locates them within a conceptual framework (the ‘production of welfare’). It also examines some of the reasons for the growth in interest in them. The main modes of evaluation—cost-benefit, cost-effectiveness, cost-utility and cost-consequences analyses—are described and illustrated. Few such evaluations have been conducted in child care, and the paper ends with speculation as to why this is so.  相似文献

This study proposes a micro‐institutional theory of political violence, according to which citizens' participation in political violence is partially an outcome of tight coupling of persons' practices and self‐identifications with institutional logics opposed to dominant logics associated with world culture, such as the nation‐state and gender equality. The study focuses on two types of institutional carriers through which persons adopt institutional logics: routine practices and self‐identifications associated with three institutional logics: the familial, the ethnic, and the religious logics. Using a 15‐country survey data from early twenty‐first‐century sub‐Saharan Africa, the study finds evidence in support of the theory. Reported participation in political violence is associated with practices and self‐identifications uncoupled from dominant world‐culture logics but tightly coupled with the patriarchal familial logic, with an oppositional ethnic logic, and with a politicized oppositional religious logic.  相似文献

The possibilities that are available to youth in contemporary Western societies are highly sophisticated and related mostly to the transition between secondary school and higher education, the first job placement, independent housing, lifestyle construction and the consumption of goods produced by cultural industries in a globalist world. Secondary education represents a main factor in terms of socialisation, training, access to employment, citizenship and youth identity construction, making it a key for public policies aimed at youth in Latin America. The article presents the initial results of a research project on transition processes from secondary school to employment in Argentina. The findings are based on statistical information and the empirical analysis of data gathered in two very different economic and social contexts: the first was one of the worst social and economic crisis in the country's history (1999–2003), and the second was a long period of economic growth and increased social welfare (2004–2012). The data are presented in response to the following question: How do different economic contexts influence the transitions of youth in different social class contexts? By answering this question, the significant role of public policies in generating better living conditions for youth becomes clear.  相似文献
