This paper presents a dynamic perspective in which the psychological contract is treated as a structured set of beliefs that are held by individual employees about the mutual obligations of the organization as employer and themselves as employees. This set of beliefs is assumed to produce a state of commitment to the organization in which the employee is willing to accept work roles and tasks offered by the organization, and to carry them out in accordance with certain standards. The dynamic (...) model that is presented can help to explain why the commitment of employees remains relatively stable over time, and why it may suddenly decrease or increase under circumstances that are perceived as critical by the employee. The model assumes that the employee's evaluation of the organization's behavior changes over time, but that the structure of the psychological contract and the associated commitment change only when certain limits are overstepped. This perspective on changes in the psychological contract transforms the concept into a powerful construct that may lead to fruitful research on the dynamics of organization-employee relationships. Implications for future research are discussed. (shrink)

Is knowledge possible? If so, what can we know and how do we come to know it? What degree of certainty does our knowledge enjoy? In these two powerful works, Descartes, the seventeenth-century philosopher considered to be the father of modern philosophy, outlines his philosophical method and then counters the skeptics of his time by insisting that certain knowledge can be had. He goes on to address the nature and extent of human knowledge, the distinction between mind and body, the (...) existence of God, and the existence of external objects. (shrink)

The Philosophical Writings of Descartes VOLUME 3. Volumes 1 and 2 provide a completely new translation of many of the major works in metaphysics, epistemology, and natural philosophy.

Based on the new and much acclaimed two volume Cambridge edition of The Philosophical Writings of Descartes by Cottingham, Stoothoff, and Murdoch, this anthology of essential texts contains the most important and widely studied of those writings, including the Discourse and Meditations and substantial extracts from the Regulae, Optics, Principles, Objections and Replies, Comments on a Broadsheet, and Passions of the Soul.

This volume preserves the format in which Discourse on Method was originally published: as a preface to Descartes's writings on optics, geometry, and meteorology. In his introduction, Olscamp discusses the value of reading the Discourse alongside these three works, which sheds new light on Descartes’s method. Includes an updated bibliography.

A translation by Thomas Steele Hall, an historian of physiology, of the 1664 edition of Descartes' L'Homme (ed. Claude Clerselier). Includes an introduction, review of Descartes' physiology, a synopsis of the first French edition, bibliographical materials (editions and sources of L'Homme), and extensive interpretive notes. Also incorporates the French text of 1664 of L'Homme. Forward by I. B. Cohen.

This edition features reliable, accessible translations; useful editorial materials; and a straightforward presentation of the Objections and Replies, including the objections from Caterus, Arnauld, and Hobbes, accompanied by Descartes' replies, in their entirety. The letter serving as a reply to Gassendi--in which several of Descartes' associates present Gassendi's best arguments and Descartes' replies--conveys the highlights and important issues of their notoriously extended exchange. Roger Ariew's illuminating Introduction discusses the Meditations and the intellectual environment surrounding its reception.

How is it possible for a picture to depict a picture? Proponents of perceptual theories of depiction, who argue that the content of a picture is determined, in part, by the visual state it elicits in suitable viewers, that is, by a state of seeing-in, have given a plausible answer to this question. They say that a picture depicts a picture, in part, because, under appropriate conditions of observation, a suitable viewer will be able to see a picture in the (...) picture. In this article, I first argue that this answer is in conflict with the way in which some of the most influential perceptual theories of depiction – Robert Hopkins's version of the experienced resemblance theory and Dominic Lopes's version of the recognition theory – construe seeing-in. I then formulate a version of the recognition theory that avoids this conflict and show how it can explain the depiction of pictures. (shrink)

Representationalists hold that the phenomenal character of a perceptual experience is identical with, or supervenes on, an aspect of its representational content. As such, representationalism could be disproved by a counter-example consisting of two experiences that have the same representational content but differ in phenomenal character. In this paper, I discuss two recently proposed counter-examples to representationalism that involve ambiguous or reversible figures. I pursue two goals. My first, and most important, goal is to show that the representationalist can offer (...) plausible responses to both counter-examples. My second goal is to show the implications of these responses for the nature of the spatial representational contents of perceptual experiences. (shrink)

We give a direct, purely arithmetical and elementary proof of the strong normalization of the cut-elimination procedure for full (i.e., in presence of all the usual connectives) classical natural deduction.

Dernier ouvrage publie par Descartes, le Traite des Passions de l'ame (1649) est le fruit de toute sa philosophie. Ce traite, qui s'appuie sur un resume de la biologie cartesienne, s'oriente vers une medecine concrete des affections psycho-physiologiques et s'epanouit en une apologie de la generosite. Aux observations scientifiques, Descartes ne dedaigne pas d'adjoindre des notations psychologiques dont la finesse evoque parfois ces maximes qui fleurissaient dans les salons au XVIIe siecle. Ainsi l'ampleur des conclusions scientifiques, morales et metaphysiques, sources (...) d'etudes toujours renaissantes pour les specialistes, se colore par surcroit d'une richesse vecue qui fait de ce Traite, ecrit pour une princesse et offert a une reine, le modele des ouvrages accessibles au plus grand public.

Background: Treating medication-refractory freezing of gait in Parkinson’s disease remains challenging despite several trials reporting improvements in motor symptoms using subthalamic nucleus or globus pallidus internus deep brain stimulation. Pedunculopontine nucleus region DBS has been used for medication-refractory FoG, with mixed findings. FoG, as a paroxysmal phenomenon, provides an ideal framework for the possibility of closed-loop DBS.Methods: In this clinical trial, five subjects with medication-refractory FoG underwent bilateral GPi DBS implantation to address levodopa-responsive PD symptoms with open-loop stimulation. Additionally, PPN (...) DBS leads were implanted for CL-DBS to treat FoG. The primary outcome of the study was a 40% improvement in medication-refractory FoG in 60% of subjects at 6 months when “on” PPN CL-DBS. Secondary outcomes included device feasibility to gauge the recruitment potential of this four-lead DBS approach for a potentially larger clinical trial. Safety was judged based on adverse events and explantation rate.Findings: The feasibility of this approach was demonstrated as we recruited five subjects with both “on” and “off” medication freezing. The safety for this population of patients receiving four DBS leads was suboptimal and associated with a high explantation rate of 40%. The primary clinical outcome in three of the five subjects was achieved at 6 months. However, the group analysis of the primary clinical outcome did not reveal any benefit.Interpretation: This study of a human PPN CL-DBS trial in medication-refractory FoG showed feasibility in recruitment, suboptimal safety, and a heterogeneous clinical effect in FoG outcomes.

In his paper “Double Vision, Phosphenes and Afterimages: Non-Endorsed Representations rather than Non-Representational Qualia,” Işık Sarıhan addresses the debate between strong representationalists and qualia theorists. He argues that qualia theorists like Ned Block and Amy Kind who cite double-vision, afterimages, etc., as evidence for the existence of qualia are mistaken about the actual nature of these states. According to Sarıhan, these authors confuse the fact that these states are non-endorsed representational states with the fact that they are at least partly (...) non-representational. I argue that Sarıhan’s argument contains gaps that suggest that he misidentifi es the mistake that leads these qualia theorists to their conclusion. In my view, these qualia theorists do not confuse the fact that the states in question are non-endorsed states with the fact that they are non-representational, but rather mistake certain representational contents, or certain aspects of these contents, for qualia.

A situation, in which a finite set of players can obtain certain payoffs by cooperation can be described by a cooperative game with transferable utility, or simply a TU-game. A (point-valued) solution for TU-games assigns a payoff distribution to every TU-game. In this article we discuss a class of equal surplus sharing solutions consisting of all convex combinations of the CIS-value, the ENSC-value and the equal division solution. We provide several characterizations of this class of solutions on variable and fixed (...) player set. Specifications of several properties characterize specific solutions in this class. (shrink)

The λμ-calculus is an extension of the λ-calculus that has been introduced by M Parigot to give an algorithmic content to classical proofs. We show that Bohm's theorem fails in this calculus.

We give a procedure for counting the number of different proofs of a formula in various sorts of propositional logic. This number is either an integer (that may be 0 if the formula is not provable) or infinite.

It is a common assumption among philosophers of perception that phenomenal colors are exhaustively characterized by the three phenomenal dimensions of the color solid: hue, saturation and lightness. The hue of a color is its redness, blueness or yellowness, etc. The saturation of a color refers to the strength of its hue in relation to gray. The lightness of a color determines its relation to black and white. In this paper, I argue that the phenomenology of shadows forces us to (...) consider illumination as an additional dimension of phenomenal colors. For this purpose, I will first introduce two different interpretations of shadow-experiences, which Chalmers has called the simple and the complex interpretations, and show that they both fail to account for important phenomenal facts about shadow-experiences. I will then introduce my own alternative interpretation based on the idea that illumination is a dimension of phenomenal colors and explain how it can account for these facts. (shrink)

The anonymous author of the Syriac Liber Graduum never mentions his theological opponents. The article analyses a few examples taken from his biblical exegesis and from his most typical theological concepts and shows that these peculiar features are better explained as a hidden polemic against Marcionism, thus casting new light on the nature of the Liber Graduum and providing new data for the study of Syriac Marcionism.
