The problem of deviant causation has long vexed causalist accounts of action. This chapter argues that an account of non-deviant causation can be developed by leveraging insights from the author’s account of control. In order to understand what happens when non-deviant causation happens, it develops the notion of a comprehensive set of circumstances. This is a set of circumstances that is derived by building a causal model that includes an agent, a plan, and the agent’s location in a particular situation. What is special about the model is that it gets the causal parameters of the particular situation right. Non-deviant causation then turns out to be the normal production of behavior that is, for the agent, normal given the plan and across the comprehensive set of circumstances. After developing this account, this chapter discusses a range of problem cases for it, examines an alternative account due to Wayne Wu, and discusses how the account fares against some complaints drawn from relevant literature.

In most theoretical and descriptive treatments of English proforms it seems to be accepted that proforms replace constituents in underlying structure (i.e. phrases or clauses). The aim of the present article is to challenge this assumption. It will be demonstrated that a great many fully acceptable uses of proforms turn out to be quite problematic for the view of proforms as corresponding either to constituents or to semantic and/or syntactic units in underlying representation; nor, it turns out, do proforms necessarily refer to or denote a single (identifiable, retrievable or inferrable) entity. After a brief summary of the relevant literature, the article presents a detailed examination of the actual function and use of English proforms, focusing on a number of frequently used proforms: (i) the indefinite pronounone, (ii) the predicative proformdo so, (iii) the demonstrative pronounsthatandthoseand (iv) certain uses of the personal pronounswe/usandyou.On the basis of attested examples, it is argued that these proforms do not necessarily express a unit at any level of underlying representation. Instead an alternative account of the use of proforms is suggested, using the theory of Functional Discourse Grammar, which, with its four different levels of analysis (representing pragmatic, semantic, morphosyntactic and phonological information), possesses the kind of flexibility needed to deal with English proforms in a consistent and unified manner. Finally, an attempt is made to explain some of the constraints on the flexible system proposed.

The different theoretical approaches used in action space research are discussed; then a causal model, based on hypotheses drawn from the relevant literature, is presented. This model is tested in an empirical study on the action spaces of 3000 residents in the region of Hamburg. The results of two different path analytical test strategies of this model are reported, which show the deficiencies of prior, mainly bivariate, analyses. Finally, a cluster analysis of the respondents' activities demonstrates that the ‘sociodemographic groups’ which are traditionally used are not homogeneous in their behaviour.

Abstract:The sharing of knowledge worldwide using hypermedia facilities and fast communication protocols (i.e., Mosaic and World Wide Web) provides a growth capacity with tremendous versatility and efficacy. The example of ExPASy, a molecular biology server developed at the University Hospital of Geneva, is striking. ExPASy provides hypermedia facilities to browse through several up-to-date biological and medical databases around the world and to link information from protein maps to genome information and diseases. Its extensive access is open through World Wide Web. Its concept could be extended to patient data including texts, laboratory data, relevant literature findings, sounds, images and movies. A new hypermedia culture is spreading very rapidly where the international fast transmission of documents is the central element. It is part of the emerging new “information society”.

The entire field of information processing in medicine is today already spread out and branched to such an extent that it is no longer possible to set up a survey on relevant literature as a whole. But even in narrow parts of medical informatics it is hardly possible for the individual scientist to keep up to date with new literature. Strictly defined special bibliographies on certain topics are most helpful.In our days, problems of optimal patient scheduling and exploitation of resources are gaining more and more importance. Scientists are working on the solution of these problems in many places.The bibliography on »Patient Scheduling« presented here contains but a few basic theoretical papers on the problem of waiting queues which are of importance in the area of medical care. Most of the papers cited are concerned with practical approaches to a solution and describe current systems in medicine.In listing the literature, we were assisted by Mrs. Wieland, Mr. Dusberger and Mr. Henn, in data acquisition and computer handling by Mrs. Gieß and Mr. Schlaefer. We wish to thank all those mentioned for their assistance.

SummaryDespite evidence from 6 major clinical trials that warfarin effectively prevents strokes in atrial fibrillation, clinicians and health care managers may remain reluctant to support anticoagulant prophylaxis because of its perceived costs. Yet, doing nothing also has a price. To assess this, we carried out a pharmacoe-conomic analysis of warfarin use in atrial fibrillation. The course of the disease, including the occurrence of cerebral and systemic emboli, intracranial and other major bleeding events, was modeled and a meta-analysis of the clinical trials and other relevant literature was carried out to estimate the required probabilities with and without warfarin use. The cost of managing each event, including acute and subsequent care, home care equipment and MD costs, was derived by estimating the cost per resource unit, the proportion consuming each resource and the volume of use. Unit costs and volumes of use were determined from established US government databases, all charges were adjusted using cost-to-charge ratios, and a 3% discount rate was applied to costs incurred beyond the first year. The proportions of patients consuming each resource were estimated by fitting a joint distribution to the clinical trial data, stroke outcome data from a recent Swedish study and aggregate ICD-9 specific, Massachusetts discharge data. If nothing is done, 3.2% more patients will suffer serious emboli annually and the expected annual cost of managing a patient will increase by DM 2,544 (1996 German Marks), from DM 4,366 to DM 6,910. Extensive multiway sensitivity analyses revealed that the higher price of doing nothing persists except for very extreme combinations of inputs unsupported by literature or clinical standards. The price of doing nothing is thus so high, both in health and economic terms, that cost-consciousness as well as clinical considerations mandate warfarin prophylaxis in atrial fibrillation.

SummaryBy the term “Primary Secretion Defect” (PSD), we mean a common heterogeneous group of congenital defects of platelet secretion, characterized by a normal primary wave of platelet aggregation induced by ADP and other agonists, a normal concentration of platelet granule contents, and normal production of thromboxane A2. The biochemical abnormalities responsible for PSD are not well known. Since a secretion defect similar to PSD is found in platelets that are severely deficient of binding sites for the ADP analogue 2MeS-ADP and do not aggregate in response to ADP, we tested the hypothesis that PSD platelets have moderately decreased 2MeS-ADP binding sites, which may be sufficient for normal ADP-induced aggregation but not for potentiating platelet secretion. The specific binding of [33P]2MeS-ADP to platelets from 3 PSD patients (347,443 and 490 sites/platelet; KD 2.8-3.9 nM) was lower than to platelets from 24 normal subjects (647 [530-1102]; KD = 3.8 [2.3-7.3]) (median [range]). Normal values were found in a fourth PSD patient (710; KD 3.7). The degree of inhibition of PGE1- induced cAMP increase by 0.1 |μM ADP was lower in patients than in controls. The secretion induced by the endoperoxide analogue U46619 from normal, acetylsalicylic acid-treated platelets under conditions that prevented the formation of large aggregates was potentiated by 1 fimol/1 ADP and inhibited by apyrase. These findings indicate that a partial deficiency of the platelet ADP receptor(s) might be responsible for the defect of platelet secretion in some PSD patients and that ADP potentiates platelet secretion independently of the formation of large aggregates and thromboxane A2 production.
