Money-egalitarian-equivalent and gain-maximin allocations of indivisible items with monetary compensation

Suppose that a certain quantity M of money and a finite number of indivisible items are to be distributed among n people, all of whom have equal claims on the whole. Different allocations are presented using various criteria of fairness in the special case where each player's utility function is additively separable. An allocation is “money-egalitarian-equivalent” (MEE) if each player's monetary valuation of his or her bundle is a fixed constant. We show that there is an essentially unique allocation that is MEE and Pareto-optimal; it is also envy-free. Alternatively, the “gain” of a player may be defined as the difference between how the player evaluates his bundle and an exact nth part of the whole according to his numerical evaluation of the whole. A “gain-maximin” criterion would maximize the minimum gain obtained by any player. We show that Knaster's procedure finds an allocation which is optimal under the gain-maximin criterion. That allocation is not necessarily envy-free, so we also find the envy-free allocation that is optimal under the gain-maximin criterion among all envy-free allocations. It turns out that, even though there exist allocations that are simultaneously envy-free and Pareto-optimal, this optimal allocation may fail to be Pareto-optimal, and it may also violate monotonicity criteria.

The future from the top: Presidential perspectives on planning—Part one

This is the first part of an article which will appear in three sections in one in this copy and one each in the June and August editions. The three parts make up a long article which is a distillation of a series of conversations between the author and Chief Executives of a variety of well-known U.S. films. The findings of Dr. Rosen's survey are important in that they provide an informed view of Presidential perspectives on planning.     

Early reemployment for dislocated workers in the United States

On the basis of data from field experiments, in 1993 the United States enacted legislation requiring that all states implement Worker Profiling and Reemployment Services programmes as part of their employment and training systems. Using statistical models, these programmes identify likely dislocated unemployment insurance claimants and provide them with job search assistance during the early weeks of their unemployment. All states have now implemented these systems, and early implementation results are now available.     

Environmental Controversies,Interactional Resources,and Rural Communities: Siting Versus Exposure Disputes1

Abstract Differences in the types of social conflict occuring in facility siting disputes and toxic contamination cases are compared. An ecological-symbolic perspective and the concept of strong and weak ties are used to interpret the nature of social conflict in two rural Pennsylvania communities and in cases in the literature. Overall, community solidarity appears likely to be enhanced in siting disputes and undermined in exposure situations. To explain this, two conflict paths are developed that move from the presence or absence of the hazard agent to individual perceptions, the generation of collective threat beliefs and the formation of strong ties, the emergence of alternative leadership and its relationship to official authorities, and finally the formation of weak ties. In each case, the type of community conflict results from the nature of the perceived environmental threat and the social process that threat sets in motion. Practical implications for rural community development are discussed.     

Emerging themes in distance learning research and practice: some food for thought

With the rapid spread of distance learning as a medium for delivering instruction, the practice of distance learning has outpaced research. This paper describes major themes identified in a review of selected research papers published in the past five years. Themes include the following: definitions of distance learning and why it should be studied; identification of the major learning theories on which research is based; how collaboration can be achieved via distance learning; the role that learner characteristics play in the success of distance learning systems, and issues related to measuring the effectiveness of distance learning. The authors conclude that more research is needed to identify critical success factors for distance learning.     

Performance Related Pay in Practice: A Critical Perspective1

This paper discusses the use of performance related pay (PRP) as a means of control over the relationship between effort and reward. Taking a critical perspective, it describes how the implementation of PRP in a UK-based electronics company has been used as a device to remove trade union influence in wage-setting arrangements and to effect changes in employee behaviour. The opinions of supervisors, line managers, personnel managers and shop-floor staff are discussed and the implications for management control are assessed. The paper concludes that from management's perspective the PRP system appears to have been a success, for it has in some cases ‘commercialized’ the relationship between effort and reward, and has pre-empted expressions of employee resistance.     

On the Status and Contribution of Westin's and Altman's Theories of Privacy

This article reviews the status and contribution of Alan Westin's and Irwin Altman's theories of privacy. It summarizes, compares, contrasts, and critiques their theories of privacy and summarizes the theory and research that have been a consequence of their theories. It discusses the relationship between privacy and secrecy, an issue raised by Westin, and between privacy and the environment, an issue raised by Altman. Finally, the article considers possible contributions of social-psychological, cultural, and social-development factors to a more complete account of privacy .     

A Promissory Theory of the Duty to Tip

In this article, I argued that in contexts in which tipping is customary, there is a moral duty to tip or to explicitly tell the server that you will not be tipping. The evidence for this rests on anecdotes about people's mental states, and customers and server's intuitions about duties that would arise were a customer unable to tip his server. The promise is a speech act that is implicit in ordering food. The speech act must be matched by the server's uptake, which is implicit in her taking the order. The promise argument rests on an actual promise and not a merely hypothetical promise. If there is such a duty, then in the absence of an explicit content, its content is likely set by convention. The convention is that customers tip 15–20%. Thus, customers have a duty to tip servers 15–20%. Other purported moral considerations do not ground this duty. These include custom, desirable incentives, role‐relative obligation, and gratitude.
