It is six years since the first edition of this book was reviewedin Trusts & Trustees (See Trusts & Trustees Volume 7,Issue 5, April 2001, pp. 30–33. The new edition reflectsmany of the changes in international trust jurisdictions. Geoffrey Shindler sets the scene in his preface. His commentthat we have barely seem to have drawn breath since that firstedition is reflected in the numerous new and revised chaptersof the book. In every jurisdiction where trusts are practised,he says, the overriding concern is the extent that our thoughtshave been dominated by regulation and anti-money launderingmeasures. The trust has been used as the scapegoat for the government'sinability to deal with crime—internal and external. Heuses succinct phrases in referring to the occasional assumptionby governments that: ‘trusts must, by definition, be involvedin money laundering in  相似文献

Business rhetoric and conventional theory expect that employment regulations will have negative effects on small firms. Prior research has shown that effects are quite rare, but has not explained why. Case studies of 18 firms from three sectors identified four explanations. (1) Perceptions of effects tend to be broad and general, rather than reflections of concrete experience. (2) 'The law' is not uniform, with older laws being largely taken for granted. (3) Effects depend on competitive conditions, which are more important influences on firms than are regulations; where conditions are benign, regulations can be absorbed, but in other circumstances employment regulations can exacerbate competitive pressures. (4) A degree of informality in small firms further eases responses. By the same token, however, hopes that regulation will stimulate modernization are rarely realized.  相似文献

Physicians use the American Medical Association's Guides to the Evaluation of Permanent Impairment, 5th edition to evaluate millions of disability applicants each year. As major contributors to the chapter in the Guides devoted to assessing impairment associated with pain, we confronted the difficulties of incorporating pain into the Guides' overall evaluation system. Analysis of these difficulties is complicated by the paucity of research on the Guides, and by ambiguities and contradictions that pervade it. We propose that the ambiguities can be reduced if impairment is consistently defined in terms of organ or body part derangement, and disability in terms of activity limitations at the level of the whole person. We also propose a distinction between objective factors that may influence a person's ability to perform activities following injury. We suggest that when physicians examine disability applicants, they should evaluate both objective measures of organ or body part dysfunction and subjective reports of applicants -- especially ones regarding pain. We conclude that a comprehensive medical evaluation of disability applicant encompasses more than an impairment assessment.  相似文献

This article investigates the career of a British diplomat, William Garnett, whose unusual life has until know been neglected by historians. Garnett's papers, held at Lancashire Record Office, are a particularly rich source for historians of British diplomacy, the British Foreign Office, and overseas travel in the first two decades of the twentieth century. Garnett was often outspoken and indiscreet in his private correspondence and his archive, on which this article draws, provides valuable insights into British representation and British policy in the countries to which he was posted in the period 1902-1919.  相似文献

This is a study of a binational community indicator program for the San Diego–Tijuana metropolitan area (SDTMA). The key objective of the research was to produce a citizen-generated community indicator program (CIP). The study is closely based on the work of the two focus groups held in the two cities and offers a small program that has immediate practical potential for implementation. The program consists of a suite of thirty-five indicators for which data has been identified and provided. Fifteen of the indicators apply to Tijuana, twenty to San Diego. The program is built around principles of community well-being or quality of life (QOL). It is the first subregional attempt at the scale of the United States-Mexico Bi-National Region (BNR) to integrate existing environmental, social, and economic data into a single coherent program to inform community leaders about the condition of the SDTMA. The region covered by the CIP generally consists of the urbanized core of metropolitan Tijuana, the city of San Diego, and associated cities like Chula Vista and El Cajon within the southern part of San Diego County.  相似文献

The United States prison population is becoming more diverse and comprised of increasingly more violent inmates. Although race has been cited as a risk factor for inmate violence, most prior research had narrowly investigated White/Black differences in inmate misconduct. Using a sample of 1,005 inmates from the southwestern U.S., the current study explored racial, ethnic, and citizenship correlates among male and female prisoners. Negative binomial regression models indicated that net of controls, Hispanics and Native Americans were the most violent male prisoners, while African Americans and Native Americans were the most violent female inmates. The current study was admittedly modest in scope; however, the findings were couched within a broader, imperative sociological framework that lamented the increasing interplay between communities and prison and the role of prison as a social institution.  相似文献

Using an experimental design, this paper addresses a few basic, but important, questions about the influence of televised political advertising. How effective are different kinds of political spots in creating impressions of a candidate among viewers? Do negative ads work better than positive ads in creating favorable impressions? Do spots that focus on issues create more favorable impressions that spots that stress the traits of a candidate? Do two ads work better than one ad in creating impressions? Can the effects of a spot be undercut by a follow-up advertisement from the opposition? This paper offers some tentative answers to these questions.

Peer influence is regarded as one of the strongest determinants of juvenile delinquency and particularly adolescent substance use. A commonly held view is that social pressure from friends to use drugs and alcohol is a major contributor to substance use. Yet the notion of peer pressure, implied by the association between peer-group associations and drug behavior, is seldom tested empirically. As a crucial test of the group pressure model, this research examines the role of peer pressure in mediating the effect of differential association on individual use. Moreover, few studies examine the nature of the relationship between peers and substance use as it relates to the processes leading toand from use. Drawing on differential association and social learning theories, our research specifies the social processes (socialization, group pressure, social selection, and rationalization) which dictate particular causal pathways leading to and from substance use and then estimates the reciprocal influences among differential association, social pressure from peers, attitudes favorable toward substance use, and individual use. Using the 1977–1979 National Youth Survey panel data, we estimate a covariance structural equation model allowing for correlated measurement error. In the cross-sectional analyses, we find no main effects of overt peer pressure on substance use. Estimation of the reciprocal effects model also reveals that overt peer pressure does not significantly influence substance use and does not mediate the effect of differential association. Instead, the influences of socialization, social selection, and rationalization play significant roles in understanding substance use.An earlier version of this paper was presented at the 1994 American Society of Criminology meetings in Miami, Florida.  相似文献
