On the Owen Set of Transportation Solutions

This paper presents an axiomatic characterization of the Owen set of transportation games. In the characterization we use six properties including consistency (CONS2) and splitting and merging (SM) which are firstly proposed and defined for this setup in the present paper.     

Risk aversion and the relationship between Nash's solution and subgame perfect equilibrium of sequential bargaining

This article presents some new, intuitive derivations of several results in the bargaining literature. These new derivations clarify the relationships among these results and allow them to be understood in a unified way. These results concern the way in which the risk posture of the bargainers affects the outcome of bargaining as predicted by Nash's (axiomatic) solution of a static bargaining model (Nash, 1950) and by the subgame perfect equilibrium of the infinite horizon sequential bargaining game analyzed by Rubinstein (1982). The analogous, experimentally testable predictions for finite horizon sequential bargaining games are also presented.     

Milford Redefined: A Model of Initial and Advanced Generalist Social Work

Abstract

Social work has long sought a conceptual framework to describe its most basic approach to service delivery: generalist social work practice. A milestone in that process was the series of Milford conferences in the 1920s during which the elements of “generic casework” were first identified. This article presents a model that advances and clarifies the concepts of generalist social work as viewed at the beginning of the 1990s. Generalist social work at both the initial and advanced levels involves a way of viewing practice. It is a perspective that focuses on the interface between systems, on a client-centered and problem-focused philosophy, and on an openness to multiple theories and approaches for improving people's well-being. Practice at the initial level requires a set of competencies necessary to provide services consistent with the understanding derived from the perspective. Advanced generalist social work represents increased complexity in the learning process and greater breadth and depth of exploration in a generalist perspective rather than a uniquely different perspective from the generalist approach.     

Criteria for selecting a production control philosophy

Logistic objectives constitute a compromise between having short leadtimes and a low volume of work in progress on the one hand and a high resource loading and due date obligation on the other. Miscellaneous production planning approaches offered today provide different combinations of logistic objectives for satisfying a manufacturing strategy. To combine the strength of the various approaches into a unified system, a new approach based on a dynamic and distributed production planning methodology is proposed. To customize the approach, various analyses and specifications have to be made and for that reason some important characteristics and criteria for analysing production control philosophies will be given.     

Mini-Remnants of Three Empires: Governing West Indian Dependencies

The remnants of three almost forgotten empires (British, French and Dutch) in the North Eastern Caribbean provide some remarkable contrasts in styles of governing, notwithstanding a good deal of common ground among the resident communities. Two of these remnants actually share a single island, and the third, on another small island, is not far away. Problems and issues are identified, and a solution suggested for overcoming some of them.     

LIFESPAN AND OUTPUT

This paper develops a finite-lifetime continuous-time model of human capital acquisition. Exogenous technological progress has two aspects, a knowledge frontier and an ease-of-learning parameter. We find that as lifespan increases: (1) output per person-hour rises in a concave fashion, and (2) learning during the work-phase of life only occurs when individuals have a sufficiently long lifespan. As a result, countries that differ in the average lifespan of their inhabitants can have permanently different levels of output per person even in the presence of free trade, perfect capital markets and common production functions.

Lack of reciprocity among Dutch teachers: Validation of reciprocity indices and their relation to stress and well-being

This research presents the results of two related studies on the convergent and construct validity of three measures of reciprocity in exchange relationships at work. In Study 1, 71 Dutch teachers were interviewed about their specific investments and outcomes in the exchange relationships with their students, colleagues and school. ANOVA revealed that they reported significantly more investments than outcomes, and that the number of reported investments and outcomes mentioned varied as a function of the type of exchange relationship. Building on these results, multi-item scales were created to assess reciprocity at a detailed level for each of the three exchange relationships. Study 2 validated these specific reciprocity measures by relating them to two global assessments of reciprocity (convergent validity) as well as to measures of job stress and well-being (construct validity). LISREL-analysis of data obtained from a further sample of 224 teachers revealed that for each type of exchange relationship there were significant, consistent and meaningful relationships among the three reciprocity measures. Further, hierarchical regression analysis showed that the reciprocity measures were differentially related to job stressors and measures of well-being. Implications are discussed.
