In this groundbreaking new study, Lowell Nissen explores the use of teleological language in the study of subjects such as behaviorism, negative feedback, and natural selection. He argues that all existing analyses fail to explain how teleological language can be used legitimately, and provides his own analysis in terms of intentionality.

We examine the influence of word choices on mathematical practice, i.e. in developing definitions, theorems, and proofs. As a case study, we consider Euclid’s and Euler’s word choices in their influential developments of geometry and, in particular, their use of the term ‘polyhedron’. Then, jumping to the twentieth century, we look at word choices surrounding the use of the term ‘polyhedron’ in the work of Coxeter and of Grünbaum. We also consider a recent and explicit conflict of approach between Grünbaum (...) and Shephard on the one hand and that of Hilton and Pedersen on the other, elucidating that the conflict was engendered by disagreement over the proper conceptualization, and so also the appropriate word choices, in the study of polyhedra.

We question whether altruistic motivation links identity fusion and extreme self-sacrifice. We review two lines of research suggesting that the underlying motivation is plausibly egoistic.

There are compelling medical, ethical, and legal arguments that support mandating use of a central institutional review board for the review of clinical trials performed at multiple institutional sites. Progress against serious diseases depends on this.

PROSPERITY AND UPHEAVAL: THE WORLD ECONOMY 1945?1980 by Herman Van der Wee translated by Robin Hogg and Max R. Hall Berkeley: University of California Press, 1987. 621pp., $14.95 Van der Wee uncritically accepts that Keynesianism is responsible for post?war economic stability. Against this belief, it is argued that an analysis of the historical record shows no significant efforts at countercyclical fiscal management in the post?war era, while efforts to control the economy via monetary policy were associated with increasing instability, culminating (...) in the crisis years of the 1970s. Thus, in the American case at least, post?war stability has been the result of self?correcting market tendencies, while instability has followed government macroeconomic intervention. (shrink)

This article is the first in a series that looks at the technological transformation of Des Moines Public Schools (DMPS). It concentrates on the costs, some financial but mostly human and organizational, that are emerging as the district begins to implement its plans for dramatically increasing computer technology use. The conclusion reached here is that not only ave the costs been greatly underestimated, they may even force a gradual shift of control over the learning environment.

De Long's criticisms of our explanation of unemployment patterns in the United States are empirically false. His assertion that we have the direction of causation reversed collapses in light of the lag between artificially high wages and unemployment. Nor are his claims about the nature of cyclical movements in productivity and real wages consistent with the data. Finally, his contention that the model we present does not work in the post‐World War II era is, at best, misleading. The evidence shows (...) with remarkable consistency that government attempts to prop up wages have caused twentieth‐century increases in U.S. employment. (shrink)

Despite the recent advances in information and communication technology that have increased our ability to store and circulate information, the task of ensuring that the right sorts of information gets to the right sorts of people remains. We argue that the many efforts underway to develop efficient means for sharing information across healthcare systems and organizations would benefit from a careful analysis of human action in healthcare organizations. This in turn requires that the management of information and knowledge within healthcare (...) organizations be combined with models of resources and processes of patient care that are based on a general ontology of social interaction. The Health Level 7 (HL7) is one of several ANSI-accredited Standards Developing Organizations operating in the healthcare arena. HL7 has advanced a widely used messaging standard that enables healthcare applications to exchange clinical and administrative data in digital form. HL7 focuses on the interface requirements of the entire healthcare system and not exclusively on the requirements of one area of healthcare such as pharmacy, medical devices, imaging or insurance transactions. This has inspired the development of a powerful abstract model of patient care called the Reference Information Model (RIM). The present paper begins with an overview of the core classes of the HL7 (Version 3) RIM and a brief discussion of its “actcentered” view of healthcare. Central to this account is what is called the life cycle of events. A clinical action may progress from defined, through planned and ordered, to executed. These modalities of an action are represented as the mood of the act. We then outline the basis of an ontology of organizations, starting from the theory of speech Acts, and apply this ontology to the HL7 RIM. Special attention is given to the sorts of preconditions that must be satisfied for the successful performance of a speech act and to the sorts of entities to which speech acts give rise (e.g. obligations, claims, commitments, etc.). Finally we draw conclusions for the efficient communication and management of medical information and knowledge within and between healthcare organizations, paying special attention to the role that medical documents play in such organizations.

This article discusses the implications of moral dissonance for managers, and how dissonance induced self justification can create an amplifying feedback loop and downward spiral of immoral behaviour. After addressing the nature of moral dissonance, including the difference between moral and hedonistic dissonance, the writer then focuses on dissonance reduction strategies available to managers such as rationalization, self affirmation, self justification, etc. It is noted that there is a considerable literature which views the organization as a potentially corrupting institution and (...) a source of acute levels of moral dissonance. A simplified process model linking immoral behaviour, dissonance and rationalization is mooted, and some recent theories which question traditional dissonance models, including the free choice paradigm (FCP), are considered. The writer concludes that in the light of the above mentioned critical theories, it may be assumed that the levels of moral dissonance, and the extent of rationalization/self justification amongst managers, are more a function of personality and situational factors than previously assumed.

Despite the recent advances in information and communication technology that have increased our ability to store and circulate information, the task remains of ensuring that the right sorts of information reach the right sorts of people. In what follows we defend the thesis that efforts to develop efficient means for sharing information across healthcare systems and organizations would benefit from a careful analysis of human action in healthcare organizations, and that the communication of healthcare information and knowledge needs to rest (...) on a sound ontology of social interaction. We illustrate this thesis in relation to the HL7 RIM, which is one centrally important tool for communication in the healthcare domain. (shrink)
