Parenting is a critical factor in substance abuse prevention. Positive parenting behaviors are identified as a protective factor for substance abuse among youth. Limited research exists that investigates the role of parenting practices on minority youth substance use. The present study seeks to examine correlates between parenting and recent alcohol use among African American youth. Specifically, to what extent do African American students report experiencing specific parenting behaviors that are measured by the National Household Survey on Drug Use and Health?, do specific parenting behaviors increase the risk of recent alcohol use among African American youth?, does the impact of parenting behaviors on recent alcohol use among African American youth differ based on sex (males and females) and age category (12–13, 14–15, and 16–17 years old) were examined in this study? Logistic regression analysis of the National Household Survey on Drug Use and Health was conducted to examine the research questions. Findings indicated that parenting behaviors was associated with recent alcohol among youth. Significant differences were found for males, females, 12–13, 14–15, and 16–17 years olds. Study findings demonstrate the importance of positive parenting behaviors in youth alcohol prevention. Program specialists may target parenting as a means of preventing and reducing youth alcohol use among African American youth.  相似文献

This article addresses the concern expressed by many within the Pacific Sociological Association in recent years that their regional organization is increasingly seen by Research I University sociologists as no longer meeting their professional needs, thus leading to (a) decreasing rates of membership and participation within, (b) a decline in the amount of high quality professional work associated with, and (c) a diminishment of the professional status of, the PSA. Using data gained from a membership survey of sociologists at the 29 Research I Universities in the Western Region of the United States and Canada, the empirical basis of these claims is examined, and their possible implications explored. The results of this investigation suggest that although PSA membership among faculty members at PhD-granting institutions may have declined somewhat over time, this has occurred for a number of very comprehendible reasons, some associated with but others external to the Pacific Sociological Association as a professional organization. In light of these findings, it is the main recommendation of this paper that the PSA should continue to approach this issue in a careful and reasoned manner, doing what it reasonably can to try to meet the professional needs of Research I University sociologists in the 21st century, but being mindful not to jeopardize what has made the PSA important and attractive to its growing number of other constituencies in recent years.  相似文献

A typology of life and death was investigated in relation to demographic characteristics, social comparisons, work orientation, and depressive symptoms among 240 hospice workers who replied to a mail questionnaire. Even though conceptions of life and death are part of the same life cycle, they have often been studied separately among those who work with the dying. There was evidence for the usefulness of the typology in the study of indicators of quality of life. A discriminant analysis indicated that four types (positivists, temporal optimists, resigned futurists, and negativists) were differentiated by social‐psychological and demographic characteristics. Implications for application are suggested.  相似文献

A stable population, such that the total birthrateB(t) =B o e rot, is abruptly altered by modifying the age-specific birth rate,m(x). The survivor function remains unaltered. The modified population ultimately settles down to a stable behavior, such thatB(t) =B 1 e r 1 t . It is shown thatB 1/B 0 = (R 0 ?R 1)/[(r 0 ?r 1)R 0 Z 1], whereR 0,R 1 are the net reproduction rates before and after the change, and \(\bar Z_1 \) expected age giving birth for the stable population after the change. The age structure and transients resulting from the change are also described. The effect of an abrupt change in the survivor functionl(x) is also investigated for the simple case where the change is caused by alteringl(x) toe x l(x). It is shown that the above ratio becomes \(B_1 /B_0 = N_1 /N_0 = [1 - \smallint _0^\infty e^{ - kx} g(x)dx]/\bar Z_1 \lambda \) , whereN refers to the numbers in the population,k =r 0 + λ, andg(x) =m(x)l(x), the value before the change. A measure for the reproductive worth of the population is also established.  相似文献

At what ages should managers be recruited? Are the young managers receiving the right sort of experience at an early stage in their careers? What effect will the proposed merger have on the career prospects in the company.....? Questions such as these are likely to face every company from time to time, but finding the answers can be very difficult. The task may be made much easier through the application of some simple analytical techniques. These techniques are discussed here in the form of a case study.  相似文献
