Ministerial reshuffles are complex exercises requiring careful handling. A frequent occurrence in British government, their significance is usually seen in political terms. Prime Ministers attach great importance to maximizing the political advantages to be gained from them. This factor is the chief determinant of their logistics, the principal characteristics of which are secrecy in advance and the speed with which ministerial changes are executed. These features - as much as the frequency of ministerial changes per se - may disrupt the policy process and have serious implications for minister-civil servant power relations. Such problems could be alleviated by giving ministers advance notice of changes of post. The institution of a process of ministerial handovers would strengthen the position of incoming ministers by making them less dependent on their officials, upon whom they rely heavily for initial briefing at present.  相似文献

In many countries it is left to the discretion of the court to accept or reject conclusions based on sampling procedures as applied to the total drug exhibit. As an alternative to this subjective approach, a statistical basis is presented using binomial and hypergeometric distributions to determine a lower limit for the proportion of units in a population which contains a drug, at a given confidence level. A method for calculating the total weight of a drug present in a population within a given confidence interval is also presented. In the event of no failures (all units sampled contain a drug), a sample size of six or seven units is generally sufficient to state that a proportion of at least 0.70 of the population contains a drug at a confidence level of at least 90%. When failures do occur in the sample, point estimation is used as the basis for selecting the appropriate sample size.  相似文献

During the past decade the field of psychology of law has changed considerably. Accompanying the growth of research and practice, there has been an increase in offerings of courses in this field. The courses are offered at both undergraduate and graduate levels and cover a wide spectrum of interests. The types of courses currently being offered and the student samples enrolling in the courses are examined. In addition, a review of the major textbooks used in the courses is provided.  相似文献

In many types of social situations, individuals defend their claims to a portion of the rewards by arguing that they are just. Although a great deal of research demonstrates that individuals differ in their distribution preferences and thus their beliefs about what is fair, the literature curiously omits consideration of the consequences of these differences, especially the conflict they may engender. This paper first reviews the few attempts to address such justice conflict. The limitations of these approaches suggest concerns to be addressed in an alternative framework. The paper presents a theoretical discussion of this alternative that integrates assumptions about distribution preferences, justice beliefs, conditions fostering the emergence of justice conflict, and elements of negotiation processes as a basic framework for predictions about the bargaining strategies individuals may employ to resolve competing justice claims.  相似文献

Much attention has been paid to the nature of parent-adolescent relationships, with a frequent conclusion being that it is a time of marked disagreement between parents and their adolescents. However, other literature suggests that this time is not inherently conflictual. The purpose of this study was to examine agreement and disagreement between mothers, fathers, and adolescents on specific issues. Then, adolescent adjustment was assessed, and the degree to which it was a function of congruence with parents was examined. A modified version of the Issues Checklist was used to measure intrafamily agreement; the Revised Behavior Problem Checklist and the Harter Scale of Child's Actual Competence were completed by adolescents' social studies teachers to assess adolescent functioning. Relative to their parents, adolescents reported that they should make more decisions alone, while both mothers and fathers reported that decisions should be made jointly among all family members. Only father-adolescent congruence was found consistently to be related to adolescent functioning. Possible explanations for the present results and relevant issues pertaining to family agreement are discussed.  相似文献
