Stuart Shapiro 《Risk analysis》2011,31(6):893-901
The regulatory process is often criticized for being cumbersome and slow, much like a computer whose hard drive is fragmented by files no longer used or useful. Like such a computer, the regulatory process contains many requirements of dubious utility. These include the Paperwork Reduction Act, the Regulatory Flexibility Act, and numerous executive orders. While other parts of the regulatory process such as notice and comment and cost‐benefit analysis have received much more academic attention, these other parts of the process deserve examination as well. This article argues that such an examination will reveal that these statutes and executive orders add little of value to the regulatory process while consuming agency resources. An improved requirement for cost‐benefit analysis with distributional analysis could easily replace virtually all of these requirements and improve regulations while reducing the time needed to promulgate regulations. 相似文献

We construct a new index of media slant that measures the similarity of a news outlet's language to that of a congressional Republican or Democrat. We estimate a model of newspaper demand that incorporates slant explicitly, estimate the slant that would be chosen if newspapers independently maximized their own profits, and compare these profit‐maximizing points with firms' actual choices. We find that readers have an economically significant preference for like‐minded news. Firms respond strongly to consumer preferences, which account for roughly 20 percent of the variation in measured slant in our sample. By contrast, the identity of a newspaper's owner explains far less of the variation in slant. 相似文献

Psychiatric nurses were included in family therapy training, but few of them applied their new skills in their work settings. A seeming paradox was the lack of support given these trainees by the nursing administration. The situation became understandable when analyzed as a "family" problem; the nurses being members of the larger social system comprising the psychiatry department. Strategies were accordingly adopted to modify aspects of the system, and this facilitated more positive contributions by nurses as family therapists. 相似文献

Narrative messages are increasingly popular in health and risk campaigns, yet gain/loss framing effects have never been tested with such messages. Three experiments examined framing in narrative messages. Experiment 1 found that only the character's decision, not framing, influenced judgments about characters in a narrative derived from a prospect theory context. Experiment 2 found that a framing effect that occurred when presented in a decision format did not occur when the same situation was presented as a narrative. Using a different story/decision context, Experiment 3 found no significant difference in preference for surgery over radiation therapy in a narrative presentation compared to a non‐narrative presentation. The results suggest that health and risk campaigns cannot assume that framing effects will be the same in narrative messages and non‐narrative messages. Potential reasons for these differences and suggestions for future research are discussed. 相似文献

Fertility decline in Kinshasa 总被引:1,自引:0,他引:1
Shapiro D 《Population studies》1996,50(1):89-103
This paper examines key socio-economic changes over the past 40 years in the lives of women in Kinshasa, Zaire, and how those changes relate to observed fertility behaviour. Data from surveys carried out in 1955, 1975, and 1990 are used to highlight the remarkable shift that has taken place in the educational attainment of women: in the 1950s the vast majority of adult women had no formal education, while by 1990 the median woman had been to secondary school. This dramatic shift was accompanied by several related changes, including delays in age at marriage and increased participation in the labour market. Total fertility, which was estimated at 7.5 in the 1950s and had not changed much by 1975, appears to have fallen more recently, by about 1.5 children or more. This decline in fertility appears to be closely linked to the improvements in secondary schooling for women in Kinshasa. 相似文献

Utilizing unique data generated from the National Longitudinal Surveys of Young Women, this paper examines the labor force participation of young mothers in the months immediately preceding and following the birth of the first child. Labor supply behavior at this point in the life cycle is described in greater detail than has hitherto been available. In addition, we analyze the independent effect of several factors of interest on the probability that a young woman will be in the labor force during various intervals surrounding the first birth. 相似文献

Using data from 1869 to 1928, we estimate the effect of party control of state governments on the entry, exit, circulation, prices, number of pages, and content of Republican and Democratic daily newspapers. We exploit changes over time in party control of the governorship and state legislatures in a differences‐in‐differences design. We exploit close gubernatorial elections and state legislatures with small majorities in a parallel regression‐discontinuity design. Neither method reveals evidence that the party in power affects the partisan composition of the press. Our confidence intervals rule out modest effects, and we find little evidence of incumbent party influence even in times and places with high political stakes or low commercial stakes. The one exception is the Reconstruction South, an episode that we discuss in detail. 相似文献

边缘型人格障碍(BPD)患者通常有显著的功能行使能力损害。其特征是冲动、情绪不稳、人际困难和身份认同问题,常常导致自杀行为和自杀姿态。虽然传统上认为BPD是一种慢性持久的障碍,但近期的研究却提示它可能会随着时间流逝而有所缓解,而且心理治疗可以促进缓解。BPD的病因与童年期虐待和不恰当的依恋关系有关。由于童年期虐待和创伤的重要意义,被公认有效的创伤治疗方法——眼动脱敏与再加工(EMDR)可能作为BPD的合理备选治疗方案之一。本文中的个案所获得的良好疗效阐明了EMDR在BPD治疗中的运用,提示有理由进行深入的对照研究。 相似文献

Data from 298 motor carrier firms were analyzed to determine the nature of the strategic planning function in that industry and the relationship between planning, organization size and economic performance. Generally, motor carriers were found to perform similarly irrespective of their size or commitment to strategic planning. A number of factors are suggested to explain this phenomenon. 相似文献
