Introduction     
Gunlicks  Arthur B. 《Publius》1989,19(4):1-15
The Federal Republic of Germany celebrated its fortieth anniversaryin May 1989. In spite of the devastation brought by World WarII, the division of the country between East and West, and theloss of one-fourth of its territory, the Bonn Republic was foundedunder more propitious circumstances than was its democraticpredecessa after World War I, the Weimar Republic. Togetherwith an "economic miracle" that brought about economic growthand a high standard of living. West Germany experienced a "politicalmirracle" that led to governmental stability and a system asdemocratic as any other in Europe. Federalism has contributedto this miracle, and, in contrast to the nineteenth century,is now identified closely with democracy in Germany. The articlescontained in this volume provide a broad overview of postwarfederalism in Germany, from its origins, organization, strengths,and weaknesses, to interpretations and assessments of currenttrends and developments.  相似文献

Two factors thought to influence jurors' penalty decisions in capital trials—the nature of the crime committed and the defense's portrayal of the convicted offender's character—were examined. Mock jurors were death-qualified and exposed to one of twelve simulated penalty trials. Each trial was comprised of one of three capital crimes and one of four defense strategies. Jurors were least punitive in robbery-murder conditions and most punitive in multiple murder conditions. A conceptual argument against capital punishment was the most effective defense; a mental illness defense was the least effective. Penalty decisions were mediated by three attributional variables: (a) juror perceptions of the defendant's volition, (b) juror perceptions of the defendant's future dangerousness, and (c) juror perceptions of the relative competency of the opposing attorneys.This article is based on the author's dissertation which received an Honorable Mention in the 1985 SPSSI Dissertation Prize competition. The research was made possible by grants from the University of California, Santa Cruz and Division 41 of the American Psychological Association. The author is indebted to Craig Haney, Elliot Aronson, and Dane Archer for their valuable suggestions and support.  相似文献

Employment figures from the Mexican national census are the basis for this analysis of employment changes in Mexico between 1895-1980. The work identifies longterm trends in the volume and composition of employment and distinguishes 3 main periods in the evolution of employment. The first period, from 1895-1930, marked the end of a stage of development lasting until about 1907 in which sufficient internal stability was achieved to support Mexico's entrance into the world market. Export of agricultural products and metals was the principal focus of economic growth. Construction of roads and railroads was a central element of progress. But economic and social problems manifested in regional disparities, concentration of wealth, conflicts between economic sectors, low pay for agricultural workers, and fierce social and political control characterized the period and culminated in the Mexican Revolution. After the first decade of the 20th century the ability of the economy to absorb new workers began to decline, and the falling of crude activity rates was not reversed until the 1940s. During the 1920s, total employment increased less than 6%, reflecting a net increase of 403,000 male workers and a decrease of 110,000 female workers. The second major period of employment from 1930-1970 saw the change from an economy based on export of primary products to one based on manufacturing for the internal market. There were 2 subperiods, a stage of transition from 1930-50, the economy registered marked fluctuations, but by the 1940s the consolidation of state power and important reforms permitting expansion of the internal market were factors in an accelerated growth of employment relative to the preceding intercensal period. Despite considerable increases in agricultural employment, the relative share of the agricultural sector in total employment was beginning a decline. Employment registered the highest growth rates of the century in the 1940s and exceeded population growth. The increased employment was explained by accelerated growth and accumulation in manufacturing along with increases in commerce, services, construction, and agriculture. From 1950-70, industrial development was consolidated, and there was a generalized expansion in employment in manufacturing as well as in the secondary and tertiary sectors. The economy was less able to absorb new labor, primarily because the agricultural sector had reached the limits of expansion in both the commercial and peasant sector by 1965, at just the time that population growth was most rapid. During the 1970s, manufacturing employment grew less rapidly because of modernization, almost exclusive orientation to the internal market which limited expansion, and scarcity of funds for importing capital goods. A new model of growth will be needed if Mexico is to escape its present stagnation, and a significant share of economic activity will need to be oriented to export. Until this process is consolidated, the national economy is unlikely to show signs of sustained recuperation.  相似文献

An examination of a case in which adjunctive use of scanning electron microscopy (SEM) demonstrated the presence of unusual three-dimensional characteristics in a bite mark. Despite the fact that many bite marks do not show "depth," demonstration of the presence of this third dimension can produce significant data for evidentiary purposes. In some instances, these data may transform what seem to be class characteristics of a bite mark into individual characteristics and thus impart much more uniqueness to the evidence. Because of the high level of resolution and magnification of SEM, some three-dimensional characteristics not visible to the eye can be shown quite clearly by its use. Emphasis will be given to the value of SEM as a tool of the forensic odontologist in bite mark analysis.  相似文献
