Forecasters often disagree on revenue predictions because of differing techniques. Some states, such as Utah, have turned to the use of survey research methods to avoid this dilemma. This article reviews many of the national forecasting models examining consumer sentiment currently in use. And it compares the Utah experience with surveys used in other states.  相似文献

This article reports the results of a study of the antecedents of long-term success in community mediation. Seventy-three mediation sessions were recorded and content analyzed. The participants were interviewed at two points: immediately after mediation and 4 to 8 months later. No relationship was found between the quality of the agreements—i.e., the extent to which they solved immediate problems- and long-term success as measured by compliance, improved relations between the parties, and the absence of new problems. On the other hand, joint problem solving by the disputants was related to complainant perceptions of improved relations with the other party. Also respondent perceptions that the mediation had been fair and that all the problems had come out were related to all aspects of long-term success in the eyes of the complainant. The latter results support a procedural justice analysis of mediation and underline the importance of mediator attention to the respondent.  相似文献

In this paper we examine the legal aspects of corporate computer usage policies including their creation, management, and their relevance to corporate computer forensic investigations. Misuse of corporate computing facilities cannot only lead to a reduction in employee productivity and network bandwidth, but can also increase the risk of infection of such facilities by computer viruses and other malicious code. Moreover, it may lead to the risk of liability and legal action.  相似文献

In this article we explore how much state is necessary to make governance work. We begin by clarifying concepts of governance and the “shadow of hierarchy” and we follow this clarification with a brief overview of empirical findings on governance research in developed countries. We then discuss the dilemmas for governance in areas of limited statehood, where political institutions are too weak to hierarchically adopt and enforce collectively binding rules. While prospects for effective policymaking appear to be rather bleak in these areas, we argue that governance research has consistently overlooked the existence of functional equivalents to the shadow of hierarchy. We assert that governance with(out) government can work even in the absence of a strong shadow of hierarchy, we identify functional equivalents to the shadow of hierarchy, and we discuss to what extent they can help overcome issues of legitimacy and effectiveness in areas of limited statehood.  相似文献

This paper examines current developments in the social control of youth crime and delinquency in England and Wales. It argues that the usual critical explanations of these developments, in the form of the dispersal of discipline or the social authoritarianism thesis are inadequate. Instead, it is suggested that the punishment has taken on a more effective and efficient format in the management of this problem group than either of the above would have made possible.  相似文献

The fingernail ridge patterns of a pair of identical twins were compared to each other, their parents, and an unrelated subject. The patterns of the twins' nails showed regions of strong similarity but were distinguishable from one another. Fewer similarities were found when comparing the nails to those of the parents and the unrelated control. The twins were shown to be monozygotic by means of DNA profiling. This therefore represents the first demonstration of unique fingernail ridge patterns in subjects shown conclusively to be identical twins. When the fingernail ridge patterns were examined with a scanning electron microscope, the backscattered electron (BEI) images were found to have superior contrast when compared to the secondary electron (SEI) images.  相似文献
