This article describes the series of changes which British Telecom has gone through over the last 10 years or so— changes which have often been dramatic and highly publicized. Faced with the challenges of the fast-changing business environment of the past decade—the most obvious of which was the technological revolution—British Telecom was perceived to be safe and reliable, but slow to change and expensive. Its strengths were the widespread understanding and acceptance of the need for change, its reservoir of the necessary skills and talent, a sound commercial infrastructure and a corporate culture. The author describes the organizational changes which have taken place and looks to a future where change is endemic if a business is to survive. 相似文献

Network Evening News Coverage of Environmental Risk 总被引:2,自引:0,他引:2
Michael R. Greenberg David B. Sachsman Peter M. Sandman Kandice L. Salomone 《Risk analysis》1989,9(1):119-126
ABC, CBS, and NBC's carefully crafted and expensively produced evening news broadcasts devoted 1.7% of their air time to 564 stories about man-made environmental risks during the period from January 1984 to February 1986. Little relationship was found between amount of coverage and public health risk. Instead, the networks appeared to be using traditional journalistic determinants of news (timeliness, proximity, prominence, consequence, and human interest) plus the broadcast criterion of visual impact to determine the degree of coverage of risk issues. Government, industry, and citizens accounted for two-thirds of the sources cited by the networks. Experts and spokespersons for environmental advocacy groups were sparsely used as sources. Given the media's need for news pegs, acute and chronic risk stories were covered differently. Acute risk stories were reported in a clearly defined cycle, peaking on the second day with on-the-scene reports and film-clips of devastation. In keeping with a decrease in visual drama, later reports were shorter and emphasized legal and political considerations. Chronic risk coverage followed the release of new scientific, legal, or political information. 相似文献

Women have been traditionally ignored in health and medical research. Some reasons for this mentality include a fear of harming a woman's reproductive ability, fear that variations in the menstrual cycle could confound results, fear that a woman's body could not withstand the rigors of clinical research, and an assumption that male and female body chemistry is similar. Thankfully, these fears and assumptions are being challenged and several major data-bases, designed specifically to study women's health, have emerged. The purpose of this paper is to: (1) characterize the major longitudinal studies on women's health, (2) summarize the major discoveries from these studies that are relevant to older women, and (3) pose several future directions for research throughout the paper. 相似文献

Neighborhood disadvantage, stress, and drug use among adults 总被引:1,自引:0,他引:1
Boardman JD Finch BK Ellison CG Williams DR Jackson JS 《Journal of health and social behavior》2001,42(2):151-165
This paper explores the relationships among neighborhood disadvantage, stress, and the likelihood of drug use in a sample of adults (N = 1,101). Using the 1995 Detroit Area Study in conjunction with tract-level data from the 1990 census, we find a positive relationship between neighborhood disadvantage and drug use, and this relationship remains statistically significant net of controls for individual-level socioeconomic status. Neighborhood disadvantage is moderately associated with drug related behaviors, indirectly through increased social stressors and higher levels of psychological distress among residents of disadvantaged neighborhoods. A residual effect of neighborhood disadvantage remains, net of a large number of socially relevant controls. Finally, results from interactive models suggest that the relationship between neighborhood disadvantage and drug use is most pronounced among individuals with lower incomes. 相似文献

In an evaluation of prison-based residential drug treatment programs, the authors use three different regression-based approaches to estimating treatment effects. Two of the approaches, the instrumental variable and the Heckman approach, attempt to minimize selection bias as an explanation for treatment outcomes. Estimates from these approaches are compared with estimates from a regression in which treatment is represented by a dummy variable. The article discusses the advantage of using more than one method to increase confidence in findings when possible selection bias is a concern. Three-year outcome data for 2,315 federal inmates are used in analyses where the authors separately examine criminal recidivism and relapse to drug use for men and women. Statistical tests lead the authors to conclude that treatment reduces criminal recidivism and relapse to drug use. The treatment effect was largest when the inference was based on the Heckman approach, somewhat smaller when based on the instrumental variable approach, and smallest when based on the traditional dummy variable approach. Treatment effects for females were not statistically significant. 相似文献

This paper presents an experiential exercise for training beginning marriage and family therapists, as well as several adaptations of the format. The basic exercise consists of role playing a therapy session in which the people playing the clients speak a language that is not understood by the therapist-in-training. Although the therapist cannot understand the clients, the clients can understand the therapist. This exercise assists students to become more cognizant of the need to be cautious and curious in the cocreation of meaning in therapy. In addition, this exercise builds confidence and clinical skills, such as learning about nonverbal communication while observing process. 相似文献

This paper seeks an account of why young teens initiate consensual sexual activity. It does so by constructing statistical models aimed at distinguishing those who report having initiated sexual activity from those who have not in four samples of eighth graders from an Upstate New York county. Theoretical selection of the model variables is guided by insights from problem syndrome, control and differential association theories. From our findings we conclude the following: (1) Risk behaviors foreseen by the problem syndrome approach, including having used marijuana and having been drunk, are significant, powerful predictors of early-teen sexual activity. (2) The social setting of consensual sexual activity differs by sex at the eighth grade level. For example, having a boyfriend is a more consistent, powerful predictor variable for girls than is having a girlfriend for boys and there is evidence to support the hypothesis that boys initiate sexual activity in the context of status-seeking while girls are more likely to do so as a way of attaining approval. (3) Our findings do not give clear primacy to parents or peers as an influence on early-teen consensual sexual activity. Both control theory, usually associated with parental-influence variables, and differential association theory, usually associated with peer-influence variables, receive support. (4) The results of the research spanning a 2-year period of intensive community antiteen-pregnancy efforts by a Zero Adolescent Pregnancy (ZAP) campaign are consistent with the conclusion that such a multifaceted approach might help lower early-teen initiation of sexual activity. 相似文献

Although posttraumatic stress disorder (PTSD), anxiety, and depression are acknowledged consequences of domestic violence, little information is available on the course of recovery over time and factors that may mediate positive outcome. Fifty-nine women were assessed for the presence of PTSD and levels of anxiety and depression at time of shelter residence and again one year later. Results at follow-up indicated a significant reduction in the incidence of PTSD, although a substantial number of women continued to report a range of posttrauma symptoms. There were also significant reductions in the levels of anxiety and depression over the 12-month period. Findings indicated the particular importance of safety and the presence of social support as prerequisites for recovery. 相似文献
