This article examines the confluence of forces at work to shape U.S. policy toward Cuba since the late 1990s. Our approach examines four key factors involved in policymaking toward Cuba in this period: (1) the entry of new interest groups into the Cuba policy process and an "entrepreneurial" Congress; (2) the executive's constitutionally based interests; (3) bureaucratic interests; and (4) pressure from outside the United States. We examine U.S.–Cuba policy by describing each determinant in isolation and then by looking at the dynamic interaction among them, showing how they are linked together. In doing so, we argue that an analysis including multiple factors better explains U.S. policy toward Cuba than one that focuses on a single factor such as the power of the Cuban-American community.  相似文献

The adoption of the civil service system is the most comprehensive reform of the personnel system in the history of the People's Republic of China. The reformers want to establish a highly qualified and professional administrative corps. Elements of the reform include a merit‐based performance evaluation system that rewards good employees and punishes poor ones, open and fair competition in recruitment and promotion to assure the quality of government officials, and a system based on law that provides continuity and consistency for government policies. The article summarizes case studies of implementation challenges such as recruitment, examinations, selection and promotion, performance evaluation, training, job rotation and salary systems. The cases provide snapshots of some of the most difficult issues involved in reforming China's civil service. Copyright © 1999 John Wiley & Sons, Ltd.  相似文献

The present paper proposes and demonstrates a method for assessing strength of evidence when an earwitness claims to recognize the voice of a speaker who is familiar to them. The method calculates a Bayes factor that answers the question: What is the probability that the earwitness would claim to recognize the offender as the suspect if the offender was the suspect versus what is the probability that the earwitness would claim to recognize the offender as the suspect if the offender was not the suspect but some other speaker from the relevant population? By “claim” we mean a claim made by a cooperative earwitness not a claim made by an earwitness who is intentionally deceptive. Relevant data are derived from naïve listeners' responses to recordings of familiar speakers presented in a speaker lineup. The method is demonstrated under recording conditions that broadly reflect those of a real case.  相似文献

The Pulitzer Prize-winning historian reflects on the rich intellectual fare enjoyed over weekly lunches with Harvey Sicherman. McDougall describes Harvey's mastery of traditional geopolitical analysis, as well as his deftness in adapting strategy to the late-Cold War and post-Cold War eras.  相似文献

Using diverse conceptualisations of citizenship, this article analyses the effect of the accumulation of civic and political assets on the transformation of citizenship values among Argentine migrants to Spain and returnees. Focusing on the transnational spaces, this article analyses important civic and political capabilities accumulated by a group of migrants and explores the impact of the assets accumulated in the transnational context. This research uses data drawn from 19 Argentine immigrants to Barcelona and 30 Argentine returnees from the cities of Madrid, Barcelona and Palma de Mallorca. Findings indicate that the migratory experience generated gains in the civic and political capabilities of this group of migrants and returnees and that living in Spain promoted the development of a more responsible, analytical and, in some cases, active citizenship. As holders of ‘multiple-perspectives’, interviewees were in a privileged position to critically analyse both the sending and receiving societies. Moreover, respondents implemented a number of practices acquired in the host society, in their home society, although this transfer generally remained at an individual level.  相似文献

ABSTRACT: The incidence of rape has increased, especially in metropolitan areas, such as the city of São Paulo. In Brazil, studies about it have shown that the majority of this type of crime is committed by the relatives and persons close to the victim. This has made the crime more difficult to be denounced, as only 10% of the cases are reported to competent police authorities. Usually, cytological exams are carried out in sex crime investigations. The difficulty in showing the presence of spermatozoa is frequent, but it does not exclude the presence of male DNA. The absence of spermatozoa in material collected from rape victims can be due to several factors, including the fact that the agressor suffers from azoospermia. This condition can be the result of a successful vasectomy. As the majority of DNA in the ejaculation sample is from spermatozoa, there is much less DNA to be analyzed. This study presents the application of Y‐STRs (DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, and DYS393) in DNA analysis of sperm samples from 105 vasectomized men. The study demonstrated a great variation in DNA concentration. DNA extraction and amplification was possible in all sperm samples even in the absence of spermatozoa. The same profile was observed, for each individual, from DNA extracted from blood, pre‐ and postvasectomy semen samples. The use of markers specific for Y chromosome in sex crime cases, especially in the absence of spermatozoa, is very important, mainly because in most situations there is a small quantity of the agressor's DNA in the medium and a large quantity of the victim's DNA.  相似文献
