A bstract . The geostationary arc is an orbit in space in which a satellite , 22,300 miles up, moving at the speed at which the earth revolves, can continue to hover over a continent on earth, monitoring weather and military activities, rebroadcasting entertainment and information programs, newspaper and magazine printing plates and particularly communications. In the latter use it replaces surface microwave relay transmitters every 30 miles (which replaced the much more expensive long landlines ), at an estimated savings of more than half a billion dollars annually for this use alone. Because the orbit cannot accommodate all the applicants for slots within it, the Federal Government should grant, for an adequate fee, three year licenses, raising the fee on renewal to absorb the annual economic rent.  相似文献

Abstract . The United States Constitution is still shrouded in myths, clothed in broad terms and garbed with ambiguities. These require constant reinterpretation. If a continuing constitutional convention is thus endemic to the American political system, then is it, as Jefferson said, “a mere thing of wax in the hands of the judiciary”? Justice Jackson wrote that “we are infallible only because we are final,” but it is a maxim of American politics that the Court follows the election returns. In the last analysis, there is a higher court in a republican democracy, the Court of Public Opinion (of which scholars and publicists are the officers) which achieves revision by periodic reinterpretation and re-examination.  相似文献

The sustainability of agricultural systems has become a major focus for debates about future human survival. Much of the argument appears to rely on simplistic interpretation of ecological models, and fails adequately to define what sustainability objectives are being sought. We explore the implications of two alternative approaches to agricultural sustainability: the Critical Limits view which would require future farming systems to accept the ecosystem-imposed limits on the number of people in the world and the lifestyle they can enjoy; and the Competing Objectives view would balance agricultural sustainability with economic viability, reduction of environmental harm and fulfilling public demands for food and landscape benefits. The development of farming systems of the future will depend on which of these views is adopted by planners and policy makers.This paper challenges some of the ecological assumptions underlying the Critical Limits approach and questions the conventional view that extensive farming systems are more sustainable agriculturally than intensive systems. We may be able to deal more effectively with the environmental side effects of intensive farming systems by treating them as unwanted externalities and taking direct action to avoid or remove them rather than attempting to change fundamentally the nature of modern farming systems.To cope with the increasingly complexity and inter-connectedness of modern farming systems in the context of globalisation and potential perturbations like climate change, we need a pluralistic approach to policy, which can cope with the high levels of uncertainty in these areas and which allows maximum flexibility of response to changing circumstances.  相似文献

In recent years, the marketing literature has placed significant emphasis on market-driving and proactive market-driven behavior within firms in attempts to reconceptualize the meaning of "market orientation." For their part, market-driving firms such as Starbucks, Amazon.com, Dell, and Southwest Airlines are demonstrating how business model innovation results in sustainable advantage and superior long-term performance in a wide range of industries. In this paper, we contend that market-driving behavior is distinct from a firm's market orientation, and instead is the essence of entrepreneurial action in the Schumpeterian "creative destruction" sense. It is further argued that the firm's entrepreneurial orientation interacts with other strategic orientations, in the process determining how they are manifested and, in some cases, whether they are manifested. Furthermore, entrepreneurial orientation plays a critical role in determining transitions among various strategic orientations over time. An integrative model illustrates the dynamics of the interface between marketing and entrepreneurship from both a content and process perspective. Two case studies illustrate how trajectories can be identified in the dominant strategic orientations within companies as they evolve.  相似文献

This research applies the impression management theory of exemplification in an accounting study by identifying and measuring differences in both auditor and public perceptions of exemplary behaviors. The auditors were divided into two groups, one of which reported self-perceptions (A-S) while the other group reported their perceptions of a typical auditor (A-O). There were two separate public groups, which gave their perceptions of a typical auditor and were divided based on their levels of accounting sophistication. The more sophisticated public group was comprised of bank loan officers (LO) while the less sophisticated public group consisted of investment club members (IC). Comparisons were made on 30 behaviors contained in the AICPA Code of Professional Conduct, which served as the basis for the research instrument. Profile analysis, a special form of MANOVA technique, was used to analyze the results. A-S perceptions were the highest of the four treatment levels and were significantly higher (i.e., more exemplary) than the perceptions of both the A-O and LO groups. The more sophisticated user group (LO) provided the lowest perceptions of the four treatment levels. For at least four of the six measures, the LO treatment group perceived the typical auditor to be less exemplary than both the IC and A-O treatments. There were no differences in perceptions between the A-O group and IC. Additional analysis revealed that auditors overrated the degree to which the public relied on financial statements. However, both public groups reported a reasonably high level of reliance on financial statements when making decisions. Philip A.

Using winning percentage as a well-established proxy for market success, this article proposes a method for estimating the relative contributions of players to victories as an assessment of their worth—that is, their value to team owners or their greatness as judged by sports fans. Specifically, the proposed approach regresses winning percentage on adjusted measures of team performance (with the players of interest omitted) plus quasi-dummy variables coded to represent the participation rates of the relevant players. Though this approach lends itself to use across a wide variety of sports (professional or college football, basketball, hockey, baseball, and so on) and situations (such as season, league, and history of team), it is described primarily in the context of major league baseball and is illustrated by means of a specific empirical application to the case of the New York Yankees.  相似文献
