Two national U.S. telephone surveys of gambling were conducted, an adult survey (age 18 and over, N = 2,631) in 1999–2000 and a youth (age 14–21, N = 2,274) survey in 2005–2007. The data from these surveys were combined to examine the prevalence of any gambling, frequent gambling and problem gambling across the lifespan. These types of gambling involvement increased in frequency during the teens, reached a high level in the respondents’ 20s and 30s, and then fell off in as the respondents aged. The notion that gambling involvement generally, and especially problem gambling, is most prevalent during the teens was not supported. A comparison of the age patterns of gambling involvement and alcohol involvement showed that alcohol involvement peaks at a younger age than gambling involvement; and thus, the theory that deviant behaviors peak at an early age applies more to alcohol than to gambling.  相似文献

This paper explores the sociological behavior of firms in the pharmaceutical industry in Central and Eastern Europe as measured by funding linkages. Using the ISI Web of Science data-base, the number of research papers funded by top American and European pharmaceuticals with at least one author from Central and Eastern Europe are identified. Results indicate that Poland leads in the region by both the number of papers funded and by percentage of a firm’s total papers funded, followed closely by Hungary, Greece and the Czech Republic. Though the percentages of any firm’s linkages with a Central and Eastern European author are small (upper limit being 6.6%), this percentage is skewed due to the fact that the US is cited for 50% of papers for most firms. Roche Corporation is the top funder of papers among both US and European firms. Incidentally, zero top American pharmaceuticals were found to have an R&D center located in Central and Eastern Europe whereas European firms: GlaxoSmithKline and Sanofi-Aventis do—possibly indicating a difference in business strategy between European and American pharmaceuticals.  相似文献

This article combines relational perspectives on gender identity with social network structural perspectives on health to understand men's sexual functioning. The authors argue that network positions that afford independence and control over social resources are consistent with traditional masculine roles and may therefore affect men's sexual performance. For example, when a heterosexual man's female partner has more frequent contact with his confidants than he does--which the authors refer to as partner betweenness--his relational autonomy, privacy, and control are constrained. Analyses of data from the National Social Life, Health, and Aging Project (NSHAP) show that about a quarter of men experience partner betweennessa and that these men are 92% more likely to report erectile dysfunction. Partner betweenness is strongest among the youngest men in the sample, which may reflect changing conceptions of masculinity in later life. The authors consider several explanations for these findings and urge additional research on the links between health, gender, and network structure.  相似文献

Belief in angels and their intervention in the material world is prevalent in the United States. Theoretically, the concept of folk religion offers an instructive lens into the popularity of these beliefs, which exist inside, outside, and across official religious doctrines, and are therefore able to transcend the boundaries of specific religious traditions by appealing to a diverse array of believers. Empirical analyses from a recent national survey support the application of the concept of folk religion, demonstrating that these beliefs are present in substantial proportions across disparate subgroups. Belief in angelic intervention is prevalent among conservative and “mainline” Protestants, Catholics, those with high levels of conventional religious practice, biblical literalists, and even those who strongly believe in “paranormal” phenomena such as Bigfoot and ESP. Belief in angels and claims of angelic protection provide compelling and flexible narratives, ready cognitive attributions, and emotional comfort. Consequently, these views have strong memetic appeal and are transposable into multifarious subcultures.  相似文献

American families: trends and correlates   总被引:1,自引:0,他引:1  
Discussion focused on the nature of the roles of the family, a review of the major demographic changes (marriage, cohabitation, nonfamily households, remarriage, fertility, teenage pregnancy, and female employment) affecting the American family in the past decades, and the nature of the impact on women, men, and children. There were four major trends identified: 1) increased proportions of children living in single-parent families due to high rates of divorce and increased childbearing outside of marriage; 2) increased proportions of adults in nontraditional living arrangements; 3) increased female labor force participation during all stages of the life cycle; and 4) decreased proportions of children and increased proportions of older people out of total population due to declining mortality and fertility rates. Family formation arises out of childbearing and childrearing roles, the need for companionship and emotional support, and the opportunities for specialization and trade, and the economies of scale. The costs of family living may include the potential for disagreement, conflict, loss of privacy, and time and money. There were a number of reasons identified for not maintaining traditional families consisting of a married couple with children. The trends were for later age at marriage: 24.4 years in 1992 for women, increased cohabitation (almost 50% cohabiting prior to first marriage in 1985-86), decreased number of married couple households, and increased number of adults in non-family households. The divorce rate has risen over the past 100 years with peaks in the 1970s; the reasons were identified as increased baby boomers and new marriages, increased labor participation of women, and changes in gender roles. The stabilization and slight decline in rates may be due to a natural leveling, the likelihood of greater stability within new marriages, and the aging of the baby boomers. An anticipated increase in divorce rates in the future was also justified. Remarriage rates varied by gender, age at separation/divorce, presence of children, race/ethnicity, and education. Fertility remained stable at 1.8 during the late 1970s and early 1980s and increased slightly to 2.0 in 1989. IN 1990, there were 25% out-of-wedlock births compared to 5% in 1960. About 12% of births in 1989 were to teenagers. There has been an increase in female-headed households, the median income of which in 1992 was $13,012, or 33% of married couple income.  相似文献

Although Pakistan remains in a pretransitional stage (contraceptive prevalence of only 11.9% among married women in 1992), urban women with post-primary levels of education are spearheading the gradual move toward fertility transition. Data collected in the city of Karachi in 1987 were used to determine whether the inverse association between fertility and female education is attributable to child supply variables, demand factors, or fertility regulation costs. Karachi, with its high concentration of women with secondary educations employed in professional occupations, has a contraceptive prevalence rate of 31%. Among women married for less than 20 years, a 10-year increment in education predicts that a woman will average two-fifths of a child less than other women in the previous 5 years. Regression analysis identified 4 significant intervening variables in the education-fertility relationship: marriage duration, net family income, formal sector employment, and age at first marriage. Education appears to affect fertility because it promotes a later age at marriage and thus reduces life-time exposure to the risk of childbearing, induces women to marry men with higher incomes (a phenomenon that either reduces the cost of fertility regulation or the demand for children), leads women to become employed in the formal sector (leading to a reduction in the demand for children), and has other unspecified effects on women's values or opportunities that are captured by their birth cohort. When these intervening variables are held constant, women's attitude toward family planning loses its impact on fertility, as do women's domestic autonomy and their expectations of self-support in old age. These findings lend support to increased investments in female education in urban Pakistan as a means of limiting the childbearing of married women. Although it is not clear if investment in female education would have the same effect in rural Pakistan, such action is important from a human and economic development perspective.  相似文献
