The purpose of this study was to identify kindergarten-age predictors of early-onset substance use from demographic, environmental, parenting, child psychological, behavioral, and social functioning domains. Data from a longitudinal study of 295 children were gathered using multiple-assessment methods and multiple informants in kindergarten and 1st grade. Annual assessments at ages 10, 11, and 12 reflected that 21% of children reported having initiated substance use by age 12. Results from longitudinal logistic regression models indicated that risk factors at kindergarten include being male, having a parent who abused substances, lower levels of parental verbal reasoning, higher levels of overactivity, more thought problems, and more social problem solving skills deficits. Children with no risk factors had less than a 10% chance of initiating substance use by age 12, whereas children with 2 or more risk factors had greater than a 50% chance of initiating substance use. Implications for typology, etiology, and prevention are discussed. 相似文献

Remaining important tasks in finding and developing new drugs and vaccines for HIV/AIDS, malaria, cancer and other diseases
require continued industry research and development. Industry’s research and development pipeline has produced drugs that
have saved AIDS victims previously facing certain death, but still no cure nor vaccine is yet available. Experience with the
process of research and development indicates that it requires more than a decade of development to produce a new drug with
costs in the hundreds of millions of dollars. Intellectual property protection is critically important in assuring that drug
development continues. Partnerships between industry and the public sector have increased access to new therapies in developing
countries and promise to enhance access to both patented and generic medicines in the future.
An earlier version of this paper was presented at an international conference, “The Ethics of Intellectual Property Rights
and Patents,” held in Warsaw, Poland on 23–24 April, 2004.

The author tests the kinship of the concepts faithful aging, the centerpiece of her book, The Art of Growing Old: A Guide to Faithful Aging (1998), and development of character, central to James Hillman's book, The Force of Character and the Lasting Life (1999). Faithful aging is assessed in characters from two plays: Graham Greene's The Potting Shed and Robert Anderson's I Never Sang for My Father. Finally, Saussy reflects on the development of character as a theological issue. 相似文献

This paper poses a feminist challenge to stage models of spiritual development and suggests alternative metaphors to the common image of a heroic journey. Women's spirituality is typically more intuitive and relational than rational and individualistic and to express this, we employ metaphors of the web and the quilt. Support for the relevance of these metaphors comes from the spiritual autobiography of Jane Goodall, an anthology of African American women's writings about spirituality, and two qualitative research investigations of older women's spirituality. We conclude with an autobiographical account of our own spiritual development and engage in a dialogue-on-the-page in which we respond to each other's narratives. 相似文献

This paper investigates the relationship between the role that information technology (IT) has played in the development of
women’s employment, the possibility of women having a significant influence on the technology’s development, and the way that
the IT industry perceives women as computer scientists, users and consumers. The industry’s perception of women and men is
investigated through the portrayal of them in computing advertisements. While women are increasingly updating their technological
skills and know-how, and through this process are entering some positions in the workplace traditionally occupied by men,
these achievements are not mirrored in their social and occupational status. The computer industry and higher education have
worryingly low numbers of women, while the possibility of women influencing the development of computer technology is just
emerging in feminist research. This paper argues that, though the IT industry, through their self-regulatory codes, subscribes
to equal treatment of sexes, races and persons with disabilities, the industry nevertheless paints a stereotyped picture of
inequality when portraying men and women in computer advertisements. As long as such a perception of women prevails within
the industry, it will stand as a barrier to women having equal access to computer technology. If advertisements influence
the way society perceives major social constructs and issues, then the computing industry has a social responsibility to portray
men and women in an equal and non-stereotypical fashion.

This article considers the links between international institutions and global economic justice: how international institutions might be morally important; how they have changed; and at what those changes imply for justice. The institutional structure of international society has evolved in ways that help to undercut the arguments of those who take a restrictionist position towards global economic justice. There is now a denser and more integrated network of shared institutions and practices within which social expectations of global justice and injustice have become more securely established. But, at the same time, our major international social institutions continue to constitute a deformed political order. This combination of density and deformity shapes how we should think about international justice in general and has important implications for the scope, character, and modalities of global economic justice. Having laid out a view of normative development and where it leads, the article then examines why international distributive justice remains so marginal to current practice. 相似文献

文章讨论了不同职业发展阶段条件下组织承诺和职务投入分别对工程技术人员工作绩效和离职倾向的预测效应.针对Werbel(1984)提出的只有职业发展后期组织承诺才能有效预测离职以及Keller(1997)提出的职务投入对工程师绩效不具有预测力,论文提出了不同观点.通过问卷法对210位工程技术人员进行测量发现,无论离职倾向还是工作绩效,随着职业发展,其预测变量呈现组织承诺-职务投入-组织承诺交替出现的特征.文章对交替过程中的职业发展阶段划分及不同阶段的任务特征作了进一步探讨. 相似文献
