This paper models the increase in the participation rate of criminal behavior as either the initiation rate or the career length of criminals changes in response to increases in unemployment. Even with large instantaneous increases in unemployment, the models show a very slow increase in the criminal participation rate, giving a possible explanation of the failure of many studies to demonstrate a link between unemployment and crime levels. 相似文献

In continuation of previous light microscope investigations the question has been raised whether the criteria determined for vital muscle damage using light microscopy, could be verified and perhaps extended for the ultrastructural region. In addition to existing human pathological material taken early post mortem, muscle tissue obtained from animal experiments was also examined. The evaluation concentrated on the muscle cells, the cell organelles and the contractile apparatus. An evaluation of semi-thin-sections was carried out in parallel. The following reaction patterns could be defined as vital reactions: hypercontraction bands, zones of rupture in narrow topological relationship to organelle changes, microstructure changes with disintegration of the fibre structure, subsarcolemmic and interfibrillary oedema, decomposition of the sarcolemma. The earliest vital reactions were detectable after only a few minutes survival time. The comparison between the results of animal experiments and human pathology and the application of the results to forensic pathology will be discussed. 相似文献

Most trial attorneys believe that repeated jury service produces several effects in jurors, one of the most important of which is an increased disposition toward conviction of criminal defendants. However, case law reveals a reluctance to accept the proposition that prior service per se would disquality a juror from sitting on an instant case because of actual or implied bias. The need for direct empirical investigation of the effects of prior jury service prompted the present study, which examined a complete docket of 175 consecutive criminal trials across onecalendar year in a state circuit court which required a 30-day term of its venire. The results indicated that as the number of jurors with prior jury experience increased there was a modest, but significant, increase in the probability of a conviction. Analysis of the relationship between initial verdicts and subsequent service disconfirmed the alternative hypothesis that attorneys deselected jurors on the basis of their first verdicts. Several parameters of experience were also related to foreperson selection. Implications for legal practice and for additional research are discussed.Support for this research was provided, in part, by National Science, Foundation grant No SES-8209479.

This paper examines the relationship between the mobilization of resources into capital projects and the completion of new productive capacity in two ‘shortage’ economies—China and the USSR. Causes of delayed commissioning of new capacity, and the role of unfinished construction in the investment cycle, are analysed. Annual data over a long period are presented for both economies—for the USSR 1928–37 and 1950–83, and for China 1950–82. Changes over time in the relationship between investment mobilization and capacity completion are considered, along with differences and similarities between the records of the two economies under investigation. 相似文献

A simple and rapid method for isolation of five butyrophenones with Sep-Pak C18 cartridges from human samples, and their wide-bore capillary gas chromatography (GC), are presented. The GC was made by both flame ionization and electron capture detections. The drugs contained in alkaline samples were directly applied to the cartridges and eluted with chloroform/isopropanol (9:1). The recoveries with use of the cartridges were excellent for most drugs in both urine and plasma samples. We can recommend the Sep-Pak C18 cartridges for isolation of butyrophenones because of simplicity and rapidity, and also wide-bore capillary GC because of high sensitivity and low decomposition of drugs during passage through the column. 相似文献
