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

This paper uses anecdotal evidence to identify a group of firms that had significant ties to President Lyndon Johnson and determines the effect of Johnson's unexpected rise to the Presidency on the market value of these firms. The unexpected nature of President Kennedy's death eliminates the confounding event problem typically associated with election results. We are able to identify four separate portfolios of firms that had political ties to Lyndon Johnson. Our research suggests that the market expected significant benefits to accrue to these firms as a result of Johnson's becoming President. When Catholic John Kennedy and Johnson were running together in 1960 a joke hop-scotched around the parties in Texas and Washington that Kennedy had told Johnson, “Lyndon, when we get elected I'm going to dig a tunnel to the Vatican,” and Lyndon had replied, “That's OK with me as long as Brown & Root gets the contract” (Dugger, 1982: 286). 相似文献

Abstract: This article focuses on competition for votes between parties, as it existed in Western Europe in the period of the direct election to the European Parliament in 1989. Following earlier research by Van der Eijk and Niemöller, an instrument is introduced to measure the probability of party choice of EC citizens which establishes the likelihood of respondents to vote for any of the nationally relevant options/parties. A number of substantive conclusions about political parties'competitive performance result from this research. First, a single mechanism seems to structure electoral competition in all EC member-countries. Second, the competitive performance of political parties is not affected by their governmental status, their ideological position, and the degree of politicisation of the electoral environment. And third, parties'competitive performance is strongly affected by the degree of uniqueness of their electoral potential, their mobilising capacities, their ideological extremity and their sheer size. 相似文献

This article proposes a diffusion of responsibility perspective in analyzing post–World War II politics in the United States. Many analysts test the American system by a responsible party perspective, proposing reforms that will orient the system toward the goals of that model. Divided government has characterized much of the period since 1945 and identifiable (and wholly constitutional) politics has accompanied that development. The diffusion of responsibility alternative is characterized by a separated presidency, an expansive Congress, competition between the branches for shared power, and, absent a crisis, a tendency toward perpetuation. 相似文献
