Abstract In this study, the internal reliability and construct validity of the recently adapted Swedish version of the Novaco Anger Scale (NAS-1998-S; Lindqvist, Dåderman, & Hellström, Social Behavior and Personality, 8, 773–788, 2003), as well as its scale correlations with demographic and criminality variables, were investigated. Construct validity was established by assessing the correlation pattern of the scales of NAS-1998-S with concurrent scales of similar and distinct constructs. Ninety-five male violent prisoners, ranging in age from 18 to 67 years, participated. The results demonstrated good internal reliability, consistent intrascale relationships, and appropriate construct validity of NAS-1998-S. The number of previous convictions had a moderate negative relationship with the capacity of control. Age and education correlated negatively with the NAS-1998-S scales, except Regulation. In addition to psychometric issues, the results were discussed from a clinical perspective on the offender population. 相似文献

Courts have increasingly looked to the concept of “transformative use” to determine whether the use of a copyrighted work is protected under the fair use doctrine. Judge Pierre Leval's definition of transformative use, adopted by the Supreme Court of the United States in its 1994 opinion in Campbell v. Acuff-Rose Music, Inc., requires that a transformative use must (1) be socially beneficial, (2) be used in a different way or purpose from the original, and (3) add value to the original by using it as raw material to create something new. This article examines the fair use analysis undertaken by the United States Court of Appeals for the Ninth Circuit in two recent cases involving visual search engines and concludes that the court's test of transformative use ignored the language and the meaning of the Campbell definition and instead equated a finding of a different purpose with a finding of a transformative use. This departure from traditional transformative use analysis, if generally adopted by the court, would represent a significant and potentially troubling doctrinal shift in fair use analysis. 相似文献

Some features of early child care are more prominent in Norway than in other countries, such as emphasis on the outdoor environment. Of general relevance and interest is the form of day care provided by forest day-care centers. Three ideas form the development of these centers placed in wild areas. First, throughout history, Norwegians have had a close attachment to nature and some parents want to provide their children with outdoor experiences at an early age. Second, urging children to play outdoors characterizes the image many parents have of a happy, healthy childhood. Third, provision of day care for children has always been restricted in western countries, forcing parents to invent types of service that can become part of an ecological system that promotes healthy development. The forest day-care centers developed recently represent a supplement to the wide typology of child care in the 21st century. The article outlines the connections between these ideas in general European and western history and Norwegian history and presents debate and decisions about a question dating from the last half of the 1980s. It concludes that the forest day-care centers are perhaps only a modern form of the original kindergarten concept, which started in Europe and America as gardens for children not gardens of children. 相似文献

Parliaments are difficult institutions to market and promote to their publics, partly because of their political nature and their institutional complexity. However, because good promotion requires a good ‘product’, thinking about parliaments in terms of their promotion can also focus attention helpfully on how they are actually structured and operated, thereby contributing to the improvement in their effectiveness, both internally and in relation to the wider polity. The Westminster and Scottish Parliaments can be usefully and conveniently compared and contrasted, both in terms of their parliamentary product, and in its promotion. such a comparative analysis highlights some of the defining characteristics of an effective parliament, such as an underlying vision and purpose, substantive institutional autonomy (especially in relation to the executive), and genuine public engagement. It also emphasises that both the operation and the promotion of a parliament are multi-layered tasks for parliamentarians and parliamentary staff. 相似文献

The term ‘infanticide’ refers to the homicide of a child younger than one year old. In this article, we describe infanticide trends in 28 industrialized countries between 1960 and 2009. The analysis is based on the cause of death data from the WHO Mortality Database and national materials. The purpose is to compare those trends in all these 28 countries not to compare countries per se. Cause of death statistics are based on ICD classification. During the review period, ICD classification changed three times. In addition to describing infanticide trends, we will analyse the impact of those changes on statistical infanticide levels, to be sure that changes in trends could be seen as real, not statistical artefacts. According to our analysis, the change from ICD-7 to ICD-9 in 1968–1970 seems to have had some impact on registered infanticide mortality levels in three of the studied countries. In other countries, the changes did not have any general impact on registered infanticide levels. During the period, infanticide rates decreased in almost all European countries, and increased or were stable in most non-European industrialized countries. Even in Europe, there were significant differences in the decreasing trend between countries. We also found some structural variation behind the trend figures, which raised the question of whether the aggregated infanticide levels really describe an identical phenomenon in different countries. 相似文献

This article introduces an exploratory framework which, on a conceptual level, suggests that the United Nations Principles for Responsible Investment can contribute to the accessibility of responsible investment and encourage institutional investors to undertake it. By co-operating with leaders of global environmental governance and by engaging with investee companies in the field of the environment, responsible investment by institutional investors may help to improve the lack of coherence in global environmental governance. 相似文献

In this paper, we examine and compare the two important production hubs in Asia: China and Greater China and India and South Asia. We show that in China, Hong Kong and Taiwan, manufacturing trade has continued to be highly relevant, with trade in parts and components growing in importance. In contrast, in India, Pakistan and Sri Lanka, trade in parts and components remain limited. We then calculate various revealed comparative advantage (RCA) indices, which China having more components with RCA values exceeding one. Some of the most important components exported by China include electronic parts and telecommunication parts. One explanation is to why India is relatively weak in parts and components trade is that India is strong in service trade. Other reasons may be related to better port infrastructure, higher research and development intensity and higher educational enrollments in China. 相似文献
