If the government decides to sell assets, how can it obtain full value? Four case studies provide valuable lessons: (1) sale of the Elk Hills oil field by the U.S. Department of Energy, (2) sales of loans and property by the Resolution Trust Corporation (RTC) after the savings and loan debacle, (3) loan asset sales by the Small Business Administration (SBA), and (4) excess property sales by the Defense Reutilization and Management Service (DRMS). The federal government should create an office to assist agencies that seek to develop effective asset sales programs.  相似文献

Abstract

British politicians often argued that Britain maintained its navy only in order to secure its own survival by keeping sea communications open, while Germany in no real need of a powerful navy, threatened this legitimate British policy-goal by pursuing expansionist politics. German leaders, emboldened and a little dazzled by the tremendous industrial and economic success of the newly unified Reich, held that Britain was maintaining its economic dominance in the Empire by military means and thus blocking the progress Germany hoped to make in its aspiration to parity status and economic prosperity, with all that that entailed. This paper will explore the underlying rationale of the arms race between Britain and Germany shining through in those different positions on legitimate (military) policy aims. It will go beyond the visible symbols, as it were, of the Dreadnought and the Two-Power standard. These very concrete matters will also be dealt with here but, more importantly, this essay is meant to give some answer as to whether an archetypal differentiation between survival on the one hand and domination on the other can be made out as the predominant logic that led the two countries to embark on the road to the Great War.  相似文献

A total of 300 motorists were recruited at public places to answer a self-report questionnaire on a new community-based intervention to enhance road safety. The intervention consisted of a speed-displaying device that was mounted next to the road and was visible to both motorists and the public. The device gives feedback about the current speed of the motorist. The majority of motorists believed these devices influenced compliance with the speed limit. They indicated they approached locations with these devices more slowly than similar locations without such devices. Moreover, they slowed down if they were going faster than the speed limit. They also said that their reaction to the devices was not influenced by whether they were driving in a community where they had friends or in a community where nobody knew them. These results were consistent across gender, age, levels of education, and professions.  相似文献

This interpretative commentary recovers the largely overlooked significance of a work that illuminates, by portraying in a subtle comic drama, the new perspective on existence, the new way of life, that Socrates introduced in and through his founding of political philosophy. The famous “problem of Socrates” as a turning point of world history (Nietzsche) remains a cynosure of controversy and puzzlement. How did Socrates understand the character of, and the relation between, civic virtue and his own philosophic virtue? What is the meaning of Socratic “eros”? What kind of educative influence did Socrates intend to have, on and through his varied followers and associates? And what diverse effects did he actually have? Xenophon's Symposium, viewed in the context of his other writings, affords a playful, but thereby deeply revealing, perspective—from the viewpoint of a slightly skeptical intimate.  相似文献

Equality of opportunity, or equality of individuals in a competition to reach unequal positions, has emerged as a fundamental cultural value over the course of American history. However, the ability of individuals to achieve desired occupations and statuses is limited by the structure of available opportunities and by the social origins of individuals. Affirmative action is an effort to engineer equality of opportunity by government intervention to promote the upward mobility of individuals with disadvantaged backgrounds. In the past, this effort has been directed primarily at compensating for the historical consequences of slavery and racial discrimination, but more recently socio-economic affirmative action has taken on the task of compensating for all disadvantages of social origin. This attempt faces several serious problems, though. It assumes that government is capable of continually re-engineering the competition. Beyond that, it aims at directing everyone toward a relatively small number of socially desired positions, promoting chronic shortages in the less-desired but necessary occupations.  相似文献

Are charges of racial disparities in the Federal Emergency Management Agency’s relief efforts in New Orleans following Hurricane Katrina accurate? Limited publicly available data on trailer distribution in New Orleans are compared to an on‐site trailer count and to a complete trailer count from aerial photographs of New Orleans. The Lower Ninth Ward in Orleans Parish (98 percent Black prior to Hurricane Katrina) had significantly fewer trailers than neighboring Arabi in St. Bernard Parish (95 percent White prior to Hurricane Katrina). To control for administrative differences between parishes and socioeconomic factors, two affluent neighborhoods within Orleans Parish, Pontchartrain Park (97 percent Black prior to Hurricane Katrina) and Lakeview (94 percent White prior to Hurricane Katrina), are compared. The conclusion: racial discrepancies remain large and substantial. A number of hypotheses are developed and the implications discussed.  相似文献

The process of coalition formation following the 2017 Bundestag election was the most difficult in German post-war history. For the first time, Germany saw negotiations fail, a minority government being discussed as a real possibility, and the federal president involved as formateur in coalition politics. The aim of this contribution is to explain why government formation was so intricate after the 2017 election. To this end, we trace patterns of party politics and the development of the German party system since 2013. We then study general patterns of government formation at the regional and national levels since the 1990s and evaluate whether these have changed with the advent of the right-wing populist party, Alternative for Germany. Our analysis of the 2017–2018 government formation is based on a novel expert survey of the policy profiles of German parties on various issue dimensions, conducted in 2017. The results show that the continuation of the incumbent coalition government of Christian and Social Democrats was the most likely outcome, and that the Social Democrats were indeed able to enforce a surpassing share of their policy positions in the final negotiation rounds.  相似文献

A sensitive immunoblotting method for the routine detection of group-specific component (GC) from fresh serum, and from control and casework bloodstains has been developed. GC phenotypes were separated in a thin layer polyacrylamide gel by isoelectric focusing, transferred to nitrocellulose by a rapid capillary blotting procedure, and detected using a double antibody enzyme immunoassay. This method is capable of phenotyping 8 ng of GC extracted from bloodstains, a four-fold increase in sensitivity when compared to immunofixation and silverstaining. A total of 2424 casework bloodstains have been analysed and GC phenotypes identified in 78% of samples. The method is suitable for use in routine laboratories and is more sensitive than other methods for GC phenotyping of casework bloodstains.  相似文献
