A small number of studies have presented data on the sociolegal correlates of inmate leadership. These studies have based their results on traditional designs of data collection, including official records and interview questionnaires. The literature has not captured reciprocal contact patterns between inmate leaders and followers, nor has research addressed the question of how leaders differ from nonleader inmates on behavioral dynamics. This article presents the results of a videotaping procedure which captures leader contact patterns in task-related decision making. The general findings support the behavioral leadership studies performed on noninmate populations and suggest that leadership is a transcendental quality which cannot be explained by the functional model of inmate subculture. 相似文献

Regulating the environmental impacts of hydroelectric schemesis of increasing importance in the light of the strong policydrive towards expanding the proportion of energy gained fromrenewable sources. Yet hydroelectric schemes are significantin another way. They provide an unusual example of a technologythat has changed little over the last 100 years and thus offersa real opportunity to judge the impact of a changing regulatoryclimate. In Scotland, three distinct phases can be detected.Earlier controls focussed on the protection of private interests,especially fishing rights, with authorisations secured throughPrivate Acts of Parliament. This was followed by a period wherepromotion of such schemes lay with public bodies; though undergeneral statutory duties, ultimately the balancing of environmentaland other interests lay with such bodies who acted with fewexternal controls. Privatisation of electricity generation in1989, coupled with the growing development of relevant EuropeanCommunity legislation, dramatically shifted the regulatory balances.Environmental Assessment requirements and now the obligationsof the Water Framework Directive have substantially alteredthe concept and scope of environmental concerns in this field. 相似文献

Many of the traditional measures of the degree to which crime patterns change over space and time have limitations. In particular most are unable to determine any change in spatial crime pattern within an areal unit. Usually studies measure the change in crime levels in contiguous areas (expressed as discrete sub-divisions of a study area), but this can become problematic due to difficulties such as the Modifiable Areal Unit Problem (MAUP). This paper describes a technique developed to allow researchers to examine intra-study region changes in crime patterns between two time periods without the need to aggregate crime counts to within-city areal boundaries. The method presented uses a random point nearest neighbor test combined with a Monte Carlo simulation. The process resolves problems of patterning and the MAUP that are common with a number of spatial displacement and pattern movement studies. This technique is demonstrated with example data from a city-wide police burglary crackdown in the Australian capital. 相似文献

Abrams and Iossifov (2006) find that during 1957–2004, monetary policy turned significantly more expansionary prior to U.S. presidential elections when the Federal Reserve chairman and the incumbent president belonged to the same political party. However, their long sample period obscures changes in trends during the period stemming from advances in macroeconomic theory and in the implementation of monetary policy. Indeed, when one considers only the Volcker–Greenspan era (1979–2004), there is insufficient evidence to accept the notion of a political business cycle effect. 相似文献
