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

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

The U.S. doesn't have democracy, it has politics. Democracy is about serving the people, giving them what they want and improving their lives. China doesn't have career politicians, it has bureaucrats. Trained and skilled administrators who are elected from the bottom and selected from the top, but only if they are good enough. If they don't measure up, they lose their job. 相似文献

A novel method for the non-destructive age determination of a blood stain is described. It is based on the measurement of the visible reflectance spectrum of the haemoglobin component using a microspectrophotometer (MSP), spectral pre-processing and the application of supervised statistical classification techniques. The reflectance spectra of sample equine blood stains deposited on a glazed white tile were recorded between 1 and 37 days, using an MSP at wavelengths between 442 nm and 585 nm, under controlled conditions. The determination of age was based on the progressive change of the spectra with the aging of the blood stain. These spectra were pre-processed to reduce the effects of baseline variations and sample scattering. Two feature selection methods based on calculation of Fisher's weights and Fourier transform (FT) of spectra were used to create inputs into a statistical model based on linear discriminant analysis (LDA). This was used to predict the age of the blood stain and tested by using the leave-one-out cross validation method. When the same blood stain was used to create the training and test datasets an excellent correct classification rate (CCR) of 91.5% was obtained for 20 input frequencies, improving to 99.2% for 66 input frequencies. A more realistic scenario where separate blood stains were used for the training and test datasets led to poorer successful classification due to problems with the choice of substrate but nevertheless up to 19 days a CCR of 54.7% with an average error of 0.71 days was obtained. 相似文献

The nanotechnology and biotechnology “revolutions” are so-called because their enabling technological breakthroughs were not
simply inventions, but discoveries of entirely new methods of inventing. We hypothesize that university participants in either
or both of these areas will exhibit greater collaboration with industry than researchers in other areas. We explore this hypothesis
for 454 faculty members who conducted research that was patented during the period 1994–1999. Because our data include patents,
publications, and funding at the individual level, we are able to examine the industry interaction of faculty who participated
in the nanotechnology and biotechnology revolutions, as well as the interaction of faculty contributing to other areas of
patentable science. We examine a variety of linkages, including sponsored research, consulting, publication with firm employees
and measures of the potential for cross-campus collaboration. The results are striking in that they show significant differences
in collaborative behavior across patent types and across the major program areas biological sciences, physical sciences and
engineering. The results are consistent with a greater degree of tacit knowledge within the new methods of inventing. We also
find significant differences in the embryonic nature and importance of patents across areas. 相似文献
