Les propriétés matérielles sont généralement appréhendées comme les propriétés d’une substance matérielle : cette chemise possède la propriété d’être bleue, cette chaussure la propriété d’être en bon état. Pourtant, on peut trouver plusieurs raisons de douter que les propriétés soient nécessairement les propriétés d’une substance matérielle, à la fois en métaphysique avec la théorie du faisceau, et en physique contemporaine à travers les notions d’énergie du vide et de champ. Or, si les propriétés ne sont pas les propriétés de substances (...) matérielles, on peut s’interroger sur la théorie de l’instanciation qu’implique une telle thèse. Dans cet essai, je m’emploierai à examiner la cohérence et la plausibilité de la thèse selon laquelle certaines, voir toutes les propriétés matérielles ne sont pas instanciées par une substance et la théorie de l’instanciation qui en découle. | : Material properties are generally construed as properties of material substances : this shirt has the property of being blue, these shoes are in good condition. However, one could think of several reasons to doubt that properties necessarily are properties of material substances both in metaphysics, with the bundle theory, and in contemporary physics, through the two notions of field and energy of the vacuum. But, if properties are not properties of material substances, what is the resulting theory of instantiation? Within the scope of this article, I will examine the consistence and plausibility of the view that several, if not all of, material properties are not instantiated by a substance and the theory of instantiation which follows from it.

En 1911, dans ses Principes du Management Scientifique, Frederick Winslow Taylor notait que toutes les activités humaines pouvaient se prêter au management. Max Weber observait, quant à lui, que la « cage de fer » bureaucratique concerne tout autant les entreprises privées que l’armée, les hôpitaux et les partis politiques. Ce qu’annonçaient le fondateur du management et le sociologue au début du xxe siècle, se réalise et même s’accomplit sous nos yeux, un siècle plus tard : la révolution m..

Résumé : Le PPBS a été conçu comme un instrument destiné à ceux qui décident de l'allocation des ressources publiques : il doit leur permettre de prendre de meilleures décisions. S'il est très difficile de repérer et de juger les choix que le développement du système a inspirés aux Etats-Unis, il n'en est pas mains certain que ses résultats tangibles sant maigres car la masse des anciens programmes, principale source potentielle de moyens nouveaux, n'a guère été remise en question.La valeur (...) intrinsèque du PPBS ne peut être mise en cause. Ce qui doit l'être, c'est la lenteur de son développement, qui demeure peu avancé. Cette lenteur s'explique, car le système ne peut produire des fruits dans une terre stérile qu'on n'a pas préparée.La brutalité et les maladresses de l'opération déclenchée en 1965 dans le gouvernement fédéral américain ne pouvaient que renforcer la résistance au changement et retarder, sinon compromettre, le succès final. Les perspectives demeurent heureusement favorables, puisque la nouvelle administration ne semble pas décidée à faire machine arrière et que les Etats et Villes ont démarré sous de bien meilleurs auspices.La principale conclusion qu'imposent les expériences américaines est que toute juridiction intéressée par le PPBS doit impérativement développer, de la façon la plus générale, la volonté d'instaurer le système et s'assurer les moyens de le faire. C'est dire qu'il est peu sage d'engager la bataille sur tous les fronts à la fois : il faut tenter des percées. Mais c'est dire aussi combi en l'information et la formation sant essentielles. A cet égard, l'installation généralisée de certains éléments du système, à savoir la structure de programmes et le budget-programme, loin de présenter des inconvénients, peut constituer un excellent exercice en dehors de son utilité directe pour le preneur de décision. La bataille en cause est surtout celle de la conviction: l'outil est prêt, il est bon, encore faut-il que l' ouvrier accepte de s'en servir.Samenvatting:Planning-programming-budgeting werd ontworpen als een instrument voor diegenen die beslissen over de toewijzing van de overheidsmiddelen.Dit instrument moet de beslissers in staat stellen betere beslissingen te treffen. Het is niet makkelijk deze beslissingen op te sporen en te beoordelen welke in de Verenigde Staten getroffen werden onder invloed van de ontwikkeling van deze systeembenadering. Toch is het met vrij grote zekerheid te stellen dat de tastbare resultaten gering zijn omdat de veelheid aan oude programma's die tenslotte toch de voornaamste potentiële bronnen zijn van nieuwe middelen, nooit werden aangevochten.De intrinsieke waarde van PPBS kan daarom evenwel niet worden genegeerd. Wat wel dient aangeklaagd is de traagheid van zijn aanslepende ontwikkeling. Deze traagheid is te verklaren door het feit dat het systeem slechts vruchten kan afwerpen zo het ingeplant wordt in degelijk voorbereid terrein.De brutaliteit en de onhandigheden bij de operatie die in 1965 werd ingezet in het amerikaans federaal overheidsbestel konden niets anders dan de weerstand tegen de verandering versterken en afbreuk doen aan het uiteindelijk slagen van het systeem. Gelukkiglijk blijven de vooruitzichten gunstig want de nieuwe beleidsvoerders sinds de presidentsverkiezingen, blijken ermee te willen doorgaan en de staten en lokale overheden zijn ermee van wal gestoken onder veel betere omstandigheden. Het doorslaggevend besluit uit de amerikaanse ervaringen terzake is wel dat elke instantie welke belangstelling heeft voor PPBS, nodig moet op zo breed mogelijk vlak de wil doen groeien om het systeem te ontwikkelen en er ook de nodige middelen toe ter beschikking stellen. Dit betekent tevens dat het weinig aan te bevelen is de strijd op alle fronten terzelvertijd aan te binden maar wel geleidelijk doorbraken te verwezenlijken. Dit brengt dan evenwel ook met zich dat informatie en vorming essentieel zijn bij deze strategie. In dit verband moet dan ook gezegd worden dat reeds het invoeren van sommige deelementen van het systeem, zoals de programmastructuur en het programmabudget, voor de beslisser nuttig kan zijn voor zijn persoonlijk inzicht en vorming.De te voeren actie dient nog slechts te worden toegespitst op het overtuigen van de verantwoordelijken. Het instrument is immers gebruiksklaar en degelijk, er is alleen nog het wachten op de wil van de gebruiker dit instrument ter hand te nemen. (shrink)

In most theories of the quantum measurement process changes in an observer’s perception of a state can take place without forces, as for example if a state is prepared in an eigenstate of \ but \ is measured. In the “special state” theory any change in wave function requires forces. This allows experimental tests to distinguish these ideas and in the present article two examples of such tests are considered. The first is a kind of double Stern–Gerlach experiment, the second (...) a check for angular momentum changes in a polarizer. (shrink)

This review of issues and research is in two parts: 1) practical problems surrounding patient-held records and 2) ethical arguments for and against patient-held records. We argue that research on patient-held records indicates that there are no substantial practical drawbacks and considerable ethical benefits to be derived from giving patients custody of their medical records.

In his paper, “Grand Unified Gauge Theories and the Number of Elementary Particles,“ Robert Weingard suggests what he calls the Extended Redhead's Principle for elementary particles: “Two particles for which there are conceivable circumstances in which one can be ‘rotated’ or reoriented into the other are the same particles”. The philosophical soundness of such a principle is questionable.

Protection of human participants is a fundamental facet of biomedical research. We report the activities of a health service research study in which there were three institutional review boards (IRBs), three legal departments and one research administration department providing recommendations and mandating changes in the study methods. Complying with IRB requirements can be challenging, but can also adversely affect study outcomes. Multiple protocol changes mandated from multiple IRBs created a research method that was not reflective of how substance use screening (...) would be performed in a clinical setting. There was direct conflict between the IRBs' perceptions of participants' protection with the researchers' need to use research methodology that assures the clinical relevancy of results. (shrink)

Walter Freeman's theory of nonlinear neurodynamics has had a major impact on brain dynamics in modern cognitive neuroscience. Steven Bressler's theory of neurocognitive networks follows from Freeman's work, and his empirical evidence for the coordination of cortical areas by phase-coupled beta rhythms in large-scale cognitive brain networks supports Freeman's ideas on nonlinear brain dynamics. Bressler's work, taking Freeman's concepts into the realm of cognitive neurodynamics, also supports Scott Kelso's theory of metastability in coordination dynamics. The aims of the present paper (...) are threefold: 1) to explore relevant concepts in Freeman's theoretical framework, 2) unify it and provide empirical support for it, and 3) explore its import for the study of consciousness. We take as our point of departure Bressler and Kelso's 2016 publication on cortical coordination dynamics and the Freeman-Kelso dialogue noted in the literature on this topic. In our view, Freeman's conceptual framework has great explanatory power. Its grounding in a dynamical systems approach to the study of brain function, and its incorporation of embodiment, make it relevant to the study of consciousness. Thus, with Freeman, we argue that the scientific understanding of consciousness must move beyond notions of computationalism and mental representations, to employ concepts of nonlinear brain dynamics and embodiment.

Few qualitative studies explore the phenomenon of positive ethical climate and what actions are perceived as promoting it. Therefore, the aim of this study was to explore and describe actions that acute care ward nurses perceive as promoting a positive ethical climate. The critical incident technique was used. Interviews were conducted with 20 nurses at wards where the ethical climate was considered positive, according to a previous study. Meeting the needs of patients and next of kin in a considerate way, (...) as well as receiving and giving support and information within the work group, promoted a positive ethical climate. Likewise, working as a team with a standard for behaviour within the work group promoted a positive ethical climate. Future research should investigate other conditions that might also promote a positive ethical climate. (shrink)

A thorough theological and exegetical study of the New Testament view of baptism. Patristic, medieval, and Reformation views fall beyond the scope of this work, yet in chapter 16 the author considers and criticizes contemporary defenses of infant baptism. Chapter 15 is a useful summary of White's position. White's treatment is judicious and not overly polemical; his scholarship is extensive and up-to-date, but restricted to works appearing in English.--L. S. F.

Hospitals in many countries have had clinical ethics committees for over 20 years. Despite this, there has been little research to evaluate these committees and growing evidence that they are underutilized. To address this gap, we investigated the question ‘What are the barriers and facilitators nurses and physicians perceive in consulting their hospital ethics committee?’ Thirty-four nurses, 10 nurse managers and 31 physicians working at four Canadian hospitals were interviewed using a semi-structured interview guide as part of a larger investigation. (...) We used content analysis of the interview data related to barriers and facilitators to use of hospital ethics committees to identify nine categories of barriers and nine categories of facilitators. These categories as well as their subcategories are discussed and those specific to nurses or physicians are identified. The need to increase health professionals' use of clinical ethics committees through reducing barriers and maximizing facilitators is discussed. (shrink)

Continuous recordings of brain electrical activity were obtained from a group of 176 patients throughout surgical procedures using general anesthesia. Artifact-free data from the 19 electrodes of the International 10/20 System were subjected to quantitative analysis of the electroencephalogram (QEEG). Induction was variously accomplished with etomidate, propofol or thiopental. Anesthesia was maintained throughout the procedures by isoflurane, desflurane or sevoflurane (N = 68), total intravenous anesthesia using propofol (N = 49), or nitrous oxide plus narcotics (N = 59). A set (...) of QEEG measures were found which reversibly displayed high heterogeneity of variance between four states as follows: (1) during induction; (2) just after loss of consciousness (LOC); (3) just before return of consciousness (ROC); (4) just after ROC. Homogeneity of variance across all agents within states was found. Topographic statistical probability images were compared between states. At LOC, power increased in all frequency bands in the power spectrum with the exception of a decrease in gamma activity, and there was a marked anteriorization of power. Additionally, a significant change occurred in hemispheric relationships, with prefrontal and frontal regions of each hemisphere becoming more closely coupled, and anterior and posterior regions on each hemisphere, as well as homologous regions between the two hemispheres, uncoupling. All of these changes reversed upon ROC. Variable resolution electromagnetic tomography (VARETA) was performed to localize salient features of power anteriorization in three dimensions. A common set of neuroanatomical regions appeared to be the locus of the most probable generators of the observed EEG changes. (shrink)
