Upland areas provide UK society with many important functions, goods and services, but have experienced a number of disturbing trends and face an uncertain future. This paper outlines historic, current and future drivers of environmental, economic, socio-cultural and policy change in UK uplands, and assesses how these have affected or are likely to affect ways in which land is used and the provision of ecosystem services. Information is synthesised into scenarios summarising a range of possible futures anticipated for UK uplands to 2060 and beyond. Finally, innovations in science, technology, governance and policy are evaluated that could enable uplands to continue providing key ecosystem services under a range of scenarios. The paper concludes that many upland areas will need to be prepared for significant reductions in grazing and prescribed burning. Conversely, other areas could experience agricultural intensification, for example significant increases in grazing or an expansion of arable or bioenergy crops into upland valleys, due to anticipated increases in global demand for food and energy. These scenarios will take place in the context of climate change. Many may take place together and may interact with each other, with complex and unpredictable implications for the upland environment, economy and society. In this context, a number of advances are needed in science, technology and policy to maintain viable upland communities and the future provision of ecosystem services. These may include funding for ecological and hydrological restoration via carbon offsetting or other means. It may also involve advances in ecosystem service modelling, mapping and valuation, which through stakeholder participation could facilitate more integrated rural planning. New forms of environmental governance need to be explored that can empower those interested in developing upland economies to maintain thriving upland communities, while managing the ecosystem services they provide as efficiently as possible.  相似文献

Dimensions of the ethical work climate, as conceptualized by Victor and Cullen (1988), are potentially important influences on individual ethical decision-making in the organizational context. The present study examined the direct and indirect effects of individuals' perceptions of work climate on their ethical judgments and behavioral intentions regarding an ethical dilemma. A national sample of marketers was surveyed in a scenario-based research study. The results indicated that, although perceived climate dimensions did not have a direct effect on behavioral intentions, there were significant moderating effects. Climates perceived as emphasizing social responsibility and rules/codes moderated the individual ethical judgment-behavioral intentions relationship such that individuals were less likely to say that they would engage in a questionable selling practice even when they themselves did not believe the practice to be unethical. Respondents were somewhat more likely to form intentions consistent with their judgment that the questionable practice was morally acceptable when the ethical climate was characterized by an emphasis on team/friendship.  相似文献

Retail futures traders face uncertainty regarding the price they will obtain when trading. This price "surprise," known as slippage, can be substantial. Using unique data from an introducing brokerage for Chicago Board of Trade (CBOT) wheat, corn, and soybean futures contracts, we quantify time-to-clear and the magnitude of slippage. We then identify factors that affect these trade quality measures. Finally, we analyze individual trader choice between market and limit orders and find that the likelihood of placing limit orders, where regulations protect traders from slippage, is greater when order and market characteristic indicate that adverse slippage is likely.  相似文献

This essay was written for the 1984 General Motors Intercollegiate Business Understanding Program. It consists of three sections, each responding to a separate issue posed by General Motors. The opinions expressed are not those of the General Motors management.The first section attempts to document, through the use of Harvard Business Review articles, a shift in the notion of managerial responsibility from a narrowly focused role responsibility to a more widely focused moral responsibility.The second section explicates the different conceptions of Justice behind the United States and West German economic systems. It gives examples of the consequences of the different conceptions both in methods of policy formation and results.The third section deals with business ethics in international contexts. It argues that law is by itself inadequate in the regulation of business activity and must be supplemented by public discussion, which employs the traditional methods of moral reasoning.John Davis Feldmann, John Kelsay, and Hugh E. Brown III are or have been graduate students in the Department of Religious Studies at the University of Virginia. Their essay, written under the direction of James F. Childress, Edwin B. Kyle Professor of Christian Ethics, won first prize in the 1984 General Motors Intercollegiate Business Understanding Program.John D. Feldmann, currently writing a dissertation on justice and tax reform, holds a law degree from the University of Virginia. He has practiced business law, served as a Vice-President of a banking corporation, and worked for the Center for Applied Ethics at the University of Virginia's Darden Graduate School of Business Administration.John Kelsay, an ordained minister of the Presbyterian Church U.S.A., holds a Ph.D. in Religious Ethics from the University of Virginia and has been serving as an Instructor there. His dissertation dealt with ethics and society in Islam.Hugh E. Brown III, now preparing for the Episcopal ministry at Virginia Theological Seminary, holds an M.A. in Religious Ethics from the University of Virginia. Prior to entering graduate school, he had experience in business as a supervisor for an AT&T affiliate.  相似文献

Capital management by mutual financial institutions (such as credit unions) provides a valuable testing ground for assessing the impact of capital regulation and theories of managerial behaviour in financial institutions. Limited access to external equity capital means that capital accumulation must be met primarily by reliance on retained earnings. To deal with shocks to the capital position and avoid breaching regulatory requirements, managers will aim to have a buffer of capital in excess of the regulatory minimum. Moreover, mutual governance arrangements and an absence of capital market discipline mean that managers have discretion to set target capital ratios which differ significantly from industry averages. This paper develops a formal model of capital management and risk management in mutual financial institutions such as credit unions which reflects these industry characteristics. The model is tested using data from larger credit unions in Australia, which have been subject to the Basel Accord Risk Weighted Capital Requirements since 1993. The data supports the hypothesis that credit unions manage their capital position by setting a short term target profit rate (return on assets) which is positively related to asset growth and which is aimed at gradually removing discrepancies between the actual and desired capital ratio. Desired capital ratios vary significantly across credit unions. There is little evidence of short run adjustments to the risk of the asset portfolio to achieve a desired capital position.  相似文献

This study reports experiments that examine outcomes when agents choose between a payment scheme that rewards based on absolute performance (i.e., piece rate) and a scheme that rewards based on relative performance (i.e., a tournament). Holding total payments in the tournament constant, performance is higher when the tournament option is winner-take-all compared to a graduated tournament (i.e., second and third-place performers also receive a payment). Performance is higher in the winner-take all tournaments even among participants that choose the piece-rate option. While there is a modest amount of overcrowding, there are no significant differences in overcrowding across conditions. Entry rates into the tournament and the relative ability of tournament entrants (compared to non-entrants in the same condition) are higher in the graduated tournament condition than the winner-take-all conditions. Consequently, the winner-take-all tournament is more efficient than the graduated tournament (incentive effects are stronger and the overcrowding is about the same), but the graduated tournament provides a more effective mechanism to identify the most capable performer in a talent pool.

Abstract.  We first discuss why fairness is a condition of the agreements among governments that form the global trading system. We then suggest that fairness can best be considered within the framework of two concepts: equality of opportunity and distributive equity. We thereafter discuss what these mean as applied to market access and its supporting rules as well as to dispute settlement and trade remedy measures. Finally, we make some comments about fairness in the Doha Development Round.  相似文献

Employee stock options (ESOs) are a popular way of remunerating employees. We analyse factors at the firm and option level affecting the employee's decision to exercise ESOs before they mature. Exercises over the period 1998–2004 are analysed and the key factor influencing early exercise is found to be dividends. Exercises frequently occur well before maturity, but in most cases little time value is sacrificed. Our findings have implications for the ‘fair’ valuation of ESOs in companies’ financial statements, as required by the relevant Australian accounting standard, AASB 2.  相似文献
