尽管网络游戏日益流行,但一直没有关于成人游戏者与未成人游戏者的比较性调查。为此,我们对EverQuest(简称EQ,中文名称为“无尽的任务”,是由美国索尼在线娱乐公司开发的知名网络游戏——译者注)游戏者(n=540)的相关特征进行了网上问卷调查。该调查主要考察了游戏玩家基本的人口学特征、游戏的频率、玩游戏的历史、游戏的偏好及玩游戏的代价等。结果表明未成年的游戏者多为男性,相较于成年游戏者,他们更不喜欢变换角色性别,更愿意牺牲学习和工作的时间。在游戏偏好的比较中,成年与非成年游戏群体的最大区别在于更多的未成年人认为他们喜好…  相似文献

Concerns over rising costs have forced police services to balance increasing fiscal and operational pressures. Discussions of the resources and requirements of police, however, are generally only informed by political expediency and traditional practice. Operational reviews (ORs) can be used to document the demands on police, their capacity to respond, and ways in which they can become more efficient and effective. Drawing on an OR of a major urban Canadian police service, this article provides a broad outline of the components of an OR and the analytics that can be used to answer these key questions.  相似文献

One set of problems facing anyone trying to track public expenditure programmes is how to handle the intergovernmental aspects. This can be illustrated by Rose and Davies's study of public expenditure in Britain. Amongst these problems are changes to the system of grants from central government to local authorities and transfers of functions between local and central government. There are also problems in the consistency with which Rose and Davies use central government grant or all of relevant expenditure in devising programmes. As a result, Rose and Davies findings about local government expenditure programmes lack consistency over time or between programmes. These discrepancies occur in what in some cases are the largest programmes in their policy area, so they also undermine the empirical and theoretical conclusions drawn about policy change as a whole in Britain. Alternative approaches and data may provide a more meaningful tracking of policy change.  相似文献

This article addresses the means of creating legislation with specific application to Wales and examines the constitutional conventions, parliamentary procedures and political processes involved. The article employs as a case study The Local Government (Wales) Act 1994. Although there are parliamentary procedures available which would allow Welsh interests a privileged role in Welsh affairs, it is found that the national interests of the political parties ensure that government ministers and the majority party in the House of Commons ultimately retain control over Welsh affairs. Nevertheless it is found that there are active policy communities with specific concerns in Welsh affairs who are prominent actors and who do give the legislative process concerning Wales distinctively Welsh characteristics.  相似文献

Numerous Calliphoridae species have been observed to form larval aggregations during the feeding stage of development, resulting in localized increases in temperature. This study investigates the relationship between maggot numbers in a mass and heat generation. Single‐species aggregations (Lucilia sericata) of various sizes (50–2500 individuals) were reared in the laboratory at a constant ambient temperature of 22°C. Internal mass temperatures were recorded every 5 min throughout the feeding stage of development. Results showed that mass temperatures increased with mass numbers (p‐value < 0.001), ranging from 2.5 to 14°C above ambient. A minimum mass size of 1200 produced overall temperatures that were significantly warmer than ambient, diverging away from 22°C after c. 26 h. These results indicate that the microclimate of a mass has the potential to differ significantly from ambient, which may be influencing larval development rates and should therefore be factored into mPMI estimates to increase accuracy.  相似文献
