Conclusion In 1984, after years of study and thorough debate, a bipartisan majority of the Congress enacted perhaps the most far-reaching reform of the federal criminal justice system in the history of the United States. The Sentencing Reform Act and the federal sentencing guidelines are now beginning to produce data indicating that the objectives of avoiding unwarranted disparity and invidious discrimination are being achieved.After an uncertain beginning, the guidelines are gaining acceptance by courts and criminal justice practitioners. As one appellate court observed in admonishing lower courts that the guidelines must be respected:We have embarked on a new course. Only time will tell whether the use of the guidelines will result in an improvement over the old system. But unless we follow the spirit and written directions of the guidelines, we will never know if they have been given a fair test. They at least deserve that.Indeed, the bold new approach to sentencing that is being followed today in federal courthouses throughout the United States deserves an opportunity to succeed, given its many beneficial features and the lofty goals toward which the reforms are directed. While ample work remains for the United States Sentencing Commission to monitor and improve the guidelines, indications at this still early date are that the experiment is succeeding.An earlier version of this paper was presented at the fifth conference of the Society for the Reform of Criminal Law, Parliament House, Edinburgh, Scotland, August 5–9, 1990. The views expressed herein are those of the authors and do not necessarily represent the official position of the United States Sentencing Commission.B.A., Davidson College 1964; J.D., University of South Carolina School of Law 1967.B.A., Ohio State University 1974; M.S., Arizona State University 1980; M.A., University of California, Santa Barbara, 1983.B.S., Clemson University 1971; M.S., Clemson University 1975; J.D., University of South Carolina School of Law 1978. 相似文献

Development debates have been greatly influenced by the growth consensus: the conventional wisdom that economic growth should be the primary priority for less-developed countries (LDCs) because it most effectively improves the well-being of the world’s poor. We compare the impact of growth to other independent variables in an unbalanced panel analysis of up to 109 LDCs and 580 observations across six time points (1980, 1985, 1990, 1995, 2000, and 2003). Our dependent variables include caloric consumption, infant survival probability, one-to-five year survival probability, female life expectancy, and male life expectancy. First, we find that gross domestic product (GDP) has significant positive effects on caloric consumption, female life expectancy, and male life expectancy. Second, GDP does not have robust effects on infant and one-to-five survival probabilities. Third, fertility, urbanization, and secondary school enrollment have larger effects than GDP in the majority of models. The more powerful effects of fertility, urbanization, and secondary schooling cannot simply be attributed to an indirect effect of GDP. Fourth, we find that dependency variables do not have robust significant effects. Fifth, over time, GDP has become much less effective at improving caloric consumption and infant and one-to-five survival. We infer that there are serious limitations to concentrating exclusively on economic growth to improve well-being in LDCs. 相似文献

In the statistical interpretation of forensic glass evidence it is standard practice to make the assumption of homogeneity of the refractive index (RI) of the source glass, or of localized homogeneity. However, the work of Locke and Hayes showed that, for toughened windscreen glass, this assumption might not be true. This work is well cited, but there appears to have been little follow-on published research. Furthermore, the toughening process is something known to affect the refractive index, and is a process that float glass does not undergo. Float glass is a major component of casework in New Zealand and for that reason it would be interesting to know whether the findings of Locke and Hayes apply when dealing with float glass. In this paper we describe an experiment similar to that of Locke and Hayes, systematically examining the variation of RI in a pane of float window glass. It was found that, although there were no systematic differences in refractive index, there were observable differences across the pane. 相似文献

This article examines the definition of success in First Nations drinking water service as voiced by the First Nations technical community of practice. The research explores success stories to identify success themes and factors to formulate a workable definition for policy‐makers. Researchers interviewed sixteen technical practitioners in Ontario using a semi‐structured approach. Data analysis revealed a definition of success that extends beyond the technical boundary to include professional growth, employment, local action and a facilitating policy environment. This comprehensive definition provides a basis for policy and program considerations to increase First Nations buy‐in and foster a constructive environment for drinking water improvements. 相似文献

Certified aircraft mechanics represent the largest gender-based demographic disparity in aviation with a 49-to-1 male-to-female ratio. Recent research into women’s perspective on the aircraft mechanic career field revealed that a large majority of women felt unsure or negatively about their potential promotion opportunities and social acceptance. The purpose of this follow-on mixed-methods concurrent triangulation study was to explore the perspectives of men regarding the aforementioned topics to see if they differ from previously published research on women perceptions. A total of 587 men and 431 women completed an eight-question survey containing 5-point Likert-type and open-ended questions. The quantitative comparison consisted of the total 1018 responses, while only the survey responses from the 587 men were analysed for correlations and qualitative codes. Results indicated that there was a significant difference between the perceptions of men from those of the women regarding work environment safety and social acceptance. Additional correlation analysis revealed social acceptance to be a key variable when predicting career appropriateness, advancement opportunity and work environment safety. The 587 qualitative responses yielded results that differed from those of women, citing an assumption that women have the same advancement opportunities or be as socially accepted as men entering the field. 相似文献

Despite positive and negative emotions being equally important predictors of adolescent wellbeing, research examining positive emotions is limited. In 4582 adolescents (69.4% females; age M?±?SD?=?14.55?±?1.74 years), we used structural equation modelling to examine associations between self-reported sleep duration and quality with positive affect, negative affect, and happiness, controlling for age and sex. Overall, sleep quality displayed stronger associations with all measures of emotions compared to sleep duration. Shorter sleep was more specifically associated with lower positive emotions (happiness, followed by positive affect), whereas poorer sleep showed stronger associations with negative affect. Protecting sleep duration may promote positive emotions and enhancing sleep quality may reduce mood disturbances. Future research could incorporate both positive and negative emotions to better understand adolescents’ wellbeing. 相似文献
