Developing and delivering new medical technologies: issues beyond access

The articles in this issue illuminate psychosocial issues raised by the development and delivery of new medical technologies. Five kinds of questions surface repeatedly: questions about a technology's purpose(s), the value judgments it presumes, the locus of its control, the external forces that drive it, and its long-term social risks. These questions take the discussion of new technologies beyond the challenge of improving access to their benefits. They also raise issues that will become increasingly important as the capabilities of medical technology expand. For example, they suggest research questions for three other emerging medical technologies: use of biosynthetic growth hormone to treat short stature in hormonally normal children, genetic tests on fetal cells from the circulating maternal blood, and development of clinically reliable biomarkers of the aging process. Part Three of this issue provides a theoretical basis for encouraging psychosocial perspectives in this area, by illustrating the central role that "robust," multifaceted analysis has come to play within the methods of bioethics.     

Australian University Students' Views of the Nuclear Arms Race: Comparative and Qualitative Analyses

Australian university students' views of the nuclear arms race were analysed in two studies. A sample comparison study used Nuclear Arms Race Questionnaire (NARQ) and Position on Nuclear Weapons (PNW) scales to compare university students' views with those of high school students and community groups. University students' views were more strongly anti-nuclear than middle income and Middle European migrant groups, but not more than high school student and church member groups'. Females' attitudes were more strongly anti-nuclear than males. A qualitative analysis of ten university students' formulations of the arms races problem and Australia's involvement revealed the complex dimensions of perceived relationships between global and national interests and personal nuclear issues. Students' solutions were directly related to their formulations of the major aspects of the arms race problem, with six students who represented the nuclear problem in terms of superpower conflict, seeing individuals as powerless to influence solutions. Quantitative trends are interpreted in light of the varied representations of the problem and the association of students' generally anti-nuclear attitudes with lack of involvement in the peace movement.     

Rationality from a computational standpoint

A computationally viable choice function possesses, in addition to other important properties, adaptability - as new alternatives become feasible the set of best alternatives corresponding to the new feasible set can be located without having to reconsider previously rejected alternatives. Adaptability is shown to be closely related to, in fact characteristic of, the standard notions of rationality (expressed in terms of transitivity properties). Adaptability provides a generalization of conventional rationality and in addition leads to the choice function proposed by Schwartz, albeit from an entirely different route, that of computational viability.     

The Financing of the Proposed Australian Health Insurance Programme

The Australian Labor Government has outlined how it intends to finance the proposed Health Insurance Programme in its recent white paper on Health Insurance, whilst the specific details are provided in the earlier Deeble Report. From these documents two important conclusions emerge. Firstly, the Government does not really know how much the scheme will cost. Secondly, the proposed methods of financing has a number of contentious aspects. It is with these two matters that this paper is concerned.     

管理伦理学视野中的“以人为本“

"以人为本"包含着诸多歧义,马克思主义在科学实践观的基础上,运用唯物辩证法和历史辩证法阐明了"以人为本"的科学内涵.从管理伦理学的视角来看,科学理解的"以人为本"是管理伦理学"何以可能"的本体论前提和承诺,是管理伦理学学科建构的基本原则,是管理伦理学的终极价值追求和理论归宿.     

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.
