The necessity of rapid objective appraisal of the suspicion of intracorporeal drug smuggling (body-packing) by effective methods of investigation in the course of the first criminal investigation department measures raises the questions of suitable and admissible methods. The proportion of undetected crimes in intracorporeal narcotic smuggling must be rated as very high according to the data of the Federal Criminal Investigation Department. In the present paper, the suitability of various imaging techniques for drug detection are reported in terms of their risk, practicability and costs. For this purpose, the value of digital radiography, two-spectra radiography and X-ray computer tomography as compared to conventional X-ray investigations is examined in human experiments. A reality-oriented narcotics dummy (glucose pressed hard in preservative) was developed and administered to nine volunteers per os with a variable initial alimentary situation. Four radiograms were taken at fixed times up to 12 hours after administration with each imaging technique. The highest rate of detection was attained with computer tomography. In contrast to the other methods, more than 90% of the body packs could be identified here. Nevertheless, an application in criminal investigation practice cannot be recommended owing to various disadvantages. The recovery rate of the remaining methods is between 20% and 25%. 相似文献

The bigger the better? Evidence of the effect of government size on life satisfaction around the world 总被引:1,自引:0,他引:1
This paper empirically analyzes whether government size is conducive or detrimental to life satisfaction in a cross-section of 74 countries. We thus provide a test of the longstanding dispute between standard neoclassical economic theory and public choice theory. According to the neoclassical view, governments play unambiguously positive roles for individuals' quality of life, while the theory of public choice has been developed to understand why governments often choose excessive involvement in – and regulation of – the economy, thereby harming their citizens' quality of life. Our results show that life satisfaction decreases with higher government consumption. For low, middle income, and male people, this result is stronger when the government is leftwing, while government consumption appears to be less harmful for women when the government is perceived to be effective. Government capital formation and social spending have no significant impact on life satisfaction. 相似文献

Parental reports of adolescent substance use were compared to the adolescents' self-reports using identical scales. Congruence was defined as exact agreement on whether adolescents were current users, ex-users, or never-users. Both parents were found to be less accurate in predicting their adolescents' alcohol use compared to cigarette or marijuana use. Single mothers were significantly less likely to be congruent than were mothers from two-parent households. Mother and father congruence on all substances was unrelated to the adolescent's sex, race, or after school employment. For both parents, congruence for adolescent marijuana use was significantly related to the age and GPA of the adolescent. Congruence may also reflect important properties of family functioning, as significant relations were found between both adolescent and parent ratings of family cohesion and parent-adolescent congruence on perceptions of marijuana use.This research was supported by Grant DA03706 from the National Institute of Drug Abuse (Hyman Hops, Principal Investigator).Jennifer Langhinrichsen is a doctoral candidate in psychology interested in adolescent and family interactions. The other authors are psychologists or data analysts working on family influences on substance use and mental health. 相似文献

As tensions in the European Monetary System demonstrate, international capital flows can have a decisive influence on countries' economic policies. The external constraint of high international capital mobility led the countries of Western Europe in the 1980s to attempt to stabilize their exchange rates and converge toward low levels of inflation. Yet this process was not uniform: French governments pursued a rigorous anti-inflationary policy of high interest rates and a strengthening currency, while Italian governments had difficulty controlling inflation and maintaining the lira in the European Monetary System. This difference is best explained by comparing political institutions and policymaking processes in the two countries. Particular attention is given to political leaders' access to economic policy tools and their capacity to design and implement long-term goals. 相似文献

Abstract. Values and ideologies seem to be changing rapidly in many countries of Western Europe. These developments imply a shift among the adherents of political parties. On the one hand, we expect to see a process of deideologization weakening the traditional ties between parties and their adherents. On the other hand, increasing pluralization is suggested by the ongoing process of individualization. In this study we analyze the orientations of the adherents of the main political parties in 12 Western European countries in the last two decades. We expect to find clear traces of ongoing deideologization as well as pluralization, but this expectation proves to be inaccurate. Neither deideologization nor pluralization can be accepted as a common feature of party adherents in advanced industrial societies. On the contrary. Each of these processes seems to follow a different path of development in distinct countries and in distinct party families. A general 'decline-of-the-party' or an 'end-of-ideology' is not to be found among the adherents of the main parties in Western Europe in the last decades. The processes appear to be more complicated, with divergent developments in different countries. 相似文献

Body image and weight loss beliefs and behaviors were assessed in 341 female and 221 male high school students. Estimates of body dissatisfaction varied depending on the measurement strategy used. Despite having similar weight distributions around the expected norm, girls were significantly more dissatisfied with their bodies than boys. Body Mass Index was positively related to body dissatisfaction in girls and boys, while higher exercise levels were related to higher body satisfaction in boys. Nearly two-thirds of girls and boys believed being thinner would have an impact on their lives, but the majority of girls believed this would be positive while the majority of boys believed this would be negative. Thirteen percent of female subjects reported using one or more extreme weight loss behavior at least weekly. Beliefs regarding the effectiveness of different weight loss measures were assessed. Weight loss behaviors in this Australian sample appear similar to comparable U.S. samples.Received Ph.D. from University of Tasmania.
