The biotechnical "revolution" has fast come upon us. It promises to produce both substantial benefits and difficult dilemmas for individuals and society. Despite the growing attention being paid to biotechnology, a major unanswered question is who shall control the development and use of the powerful array of human genetic and reproductive innovations. Should the decisions be left to individual consumers and private industry or should they be made by the government or other social institutions? After briefly reviewing development in human genetics and reproduction and describing trends toward commercialization of them, this article discusses the dilemmas these trends raise for a democratic society. It argues for the urgent need to delineate societal goals and priorities for the future and for technology assessment as early as possible in the developmental process. The article concludes by presenting some examples of the social policy problems now emerging. 相似文献

ABSTRACTIn a high-choice media environment, there are fears that individuals will select media and content that reinforce their existing beliefs and lead to segregation based on interest and/or partisanship. This could lead to partisan echo chambers among those who are politically interested and could contribute to a growing gap in knowledge between those who are politically interested and those who are not. However, the high-choice environment also allows individuals, including those who are politically interested, to consume a wide variety of media, which could lead them to more diverse content and perspectives. This study examines the relationship between political interest as well as media diversity and being caught in an echo chamber (measured by five different variables). Using a nationally representative survey of adult internet users in the United Kingdom (N?=?2000), we find that those who are interested in politics and those with diverse media diets tend to avoid echo chambers. This work challenges the impact of echo chambers and tempers fears of partisan segregation since only a small segment of the population are likely to find themselves in an echo chamber. We argue that single media studies and studies which use narrow definitions and measurements of being in an echo chamber are flawed because they do not test the theory in the realistic context of a multiple media environment. 相似文献

The paper discusses the problem of design and analysis of large scale communication systems. An iterative process, composed of a minimum cost network design algorithm and a network performance algorithm, is presented for the solution of these problems. Computational considerations, using these algorithms, are discussed. 相似文献

On a local level, creating and sustaining community schools requires leadership from local government, schools, businesses, and nonprofit organizations. These groups must provide the fuel and direction to move the community school strategy forward along a common vision and with strategic methods for financing. At the federal level, it must continue to build constituency for community schools if it is to succeed, although the community school movement has made great strides in recent years. There is not now a coherent federal framework to support the community school vision. The proposed Full Services Community Schools legislation would build a national constituency and legislate key principles advocated by the Coalition for Community Schools: developing districtwide community school strategies, focusing on results, and improving coordination of funding streams. 相似文献

In the era of managed care, evidence-based practice, and short term, solution focused interventions, clinicians in agency based settings generally do not have the luxury of long-term contact with bereaved children. Although a substantial, yet controversial, literature argues that children cannot fully resolve early loss until adulthood, limited attention is given to how children's understandings of early loss shift as their cognitive capacities mature. This article argues the emotional experience of grief shifts: 1) as children grapple with both normative life changes and the tasks of mourning, and 2) as their cognitive and emotional development allow them to understand and question aspects of their deceased parent's life and death in new ways. This article will present an overview of longitudinal and cross-sectional research on the long-term impact of childhood grief. We then suggest the ways bereaved children and adolescents revisit and reintegrate the loss of a parent as their emotional, moral, and cognitive capacities mature and as normative ego-centrism and magical thinking decline. To demonstrate these ideas, we draw on the case of a parentally bereaved boy and his family presenting across agency-based and private-practice work over the course of 14 years. This case suggests the need for coordinated care for children who are moving beyond the initial trauma of parental loss into various stages of grief and reintegration. While the loss of a parent is permanent and unchanging, the process is not: it is part of the child's ongoing experience. (Worden, 1996, p. 16). 相似文献

This paper describes a method for assessing the effectiveness of strategic planning systems in terms of the results actually observed subsequent to planning activity. The paper explains in particular how, in making the assessment, one might cope with the fact of environmental change subsequent to the setting of planned goals. This ends oriented approach to measuring effectiveness is shown to be complementary to process oriented approaches and is illustrated by an example from the coal industry. 相似文献

Until the Internet arrived, content creation and distribution was always an expensive, difficult process. With the Internet it is dramatically easier, faster, and cheaper. Some argue that this will move creation out of the hands of elites and lead to wider participation in the public sphere and to enhanced democracy. This paper makes three contributions to this debate. First, it uses a national random sample of the British population. This is much broader than most prior work. Second, it creates the first evidence-based typology of Internet content creation, identifying three types named ‘skilled content’, ‘social and entertainment content’, and ‘political content’. The implicit assumption of many researchers that only one type of content exists is not accurate. Third, using multivariate logistic regression it shows the characteristics of different populations that produce each type of content. Elites have no impact on creation of skilled content. Social and entertainment content is more likely to be created by non-elites. Only creation of political content is significantly and positively associated with elite status. These results clarify inconsistencies in prior studies. Each type of content is produced by a different kind of creator. Thus, type is more than just content; it also describes differences in who creates the content. The varying relationships between elite status and content creation suggest that it is important for future research to pay close attention to the type of content under study when considering possible democratization of creation. 相似文献

Elissen AMJ, Van Raak AJA, Derckx EWCC, Vrijhoef HJM. Improving homeless persons' utilisation of primary care: lessons to be learned from an outreach programme in The Netherlands Faced with rising homelessness, countries around the world are in need of innovative approaches to caring for those without shelter, who, more often than not, suffer from severe health problems. We conducted a case study of an innovative Dutch Primary Care for the Homeless (PCH) programme to gain insight into clients' demographic characteristics, health problems and service use, and to develop an explanation for its success in increasing the latter. Our analyses are based on a combination of quantitative and qualitative data. The results of the study suggest that the success of the PCH programme can be explained by the providers' pragmatism and will to adapt their mode of care provision to the behavioural patterns and needs of their homeless clients. 相似文献
