The Shapley value is the unique value defined on the class of cooperative games in characteristic function form which satisfies certain intuitively reasonable axioms. Alternatively, the Banzhaf value is the unique value satisfying a different set of axioms. The main drawback of the latter value is that it does not satisfy the efficiency axiom, so that the sum of the values assigned to the players does not need to be equal to the worth of the grand coalition. By definition, the (...) normalized Banzhaf value satisfies the efficiency axiom, but not the usual axiom of additivity. (shrink)
This paper describes a set of ideal type organizations in a developmental sequence. As these descriptions are based on Spiral Dynamics (or Emerging Cyclical Levels of Existence Theory – ECLET), the types are labeled as Order, Success, Community and Synergy. Per type the author elaborated on the underlying value system and relating institutional structures, such as leadership role, governance and measurement format. As a summary, a Transition Matrix is presented which indicate the paradigm shifts per discipline/department, as manifested in the (...) subsequent ideal type organizations. As Order and Success generally describe the majority of corporations in Western Economies, the latter two types introduce new approaches to more innovative – and more sustainable/responsible – ways to doing business. Based on Community Values, the author introduces a new measurement format which is the foundation for a systemic and coherent set of management tools to be used in a stakeholder approach. These tools relate to the strategic, tactical and operational tasks of management and have been developed by researchers of the European Corporate Sustainability Framework (ECSF) consortium. The set includes two tools which are generic: the Strategic Sustainability Scan (Strategy) and the Sustainability Matrix, which is a self-assessment tool (tactics). Three operational tools are context and industry specific: These are the Community related Responsive Business Scorecard (RBS) and Benchmark Format for measuring and monitoring sustainability performance and a methodology – a Management Information System – to generate information on people, planet and profit in order to provide data for the set of key performance indicators.

The European Corporate Sustainability Framework (ECSF) is, among other concepts, based on a phase-wise development approach as described by Clare Graves'' Levels of Existence Theory. As much as corporate sustainability has a sequence of adequate interpretations, aligned with each development level, also the notion of business excellence can be defined at multiple levels, as this paper demonstrates. Furthermore, the authors analyze the current EFQM Excellence Model for particular biases towards various development levels and suggest a new and innovative two-step approach (...) to assessing organizational performance with respect to organizational excellence (OE) and corporate sustainability. According to the organization''s ambition, the assessment is either limited to a shareholder approach, mainly focusing at optimal usage of resources, or it also includes an additional assessment format based on the stakeholder approach, with specific reference to the organization''s performance on the financial, social and ecological bottom line. This paper demonstrates the need and feasibility of an EFQM-Based assessment tool with a combined focus on corporate sustainability and OE. (shrink)
This article gives a practice-based and theoretical overview of the transformation from a traditional hierarchical organization in the care and cure sector towards a so-called Community-driven organization providing human happiness to 6000 elderly people. The actual case study is intertwined with conceptual information for better understanding of the innovative transition which took place at Humanitas. The case description includes its initial situation, its new core values, mission and objectives and shows the sequence of emerging policies and interventions that resulted in (...) a stakeholder oriented business model for the care sector. The selected concepts are Graves'' Emerging Cyclical Level of Existence Theory (or Spiral Dynamics), Ken Wilber''s Four Quadrant Model, Roberts Simons'' Four Levers of Control and various elements from the European Corporate Sustainability Framework sponsored by the European Commission. The conclusion marks the match between theory and practice in transforming Humanitas Rotterdam into providing cure, care, housing and well-being to elderly people. (shrink)
For purposes of this paper, a conscious state is a mental state whose subject is directly or at least nonevidentially aware of being in it. (The state does not count as conscious if the subject has only been told about it by a cognitive scientist or psychologist; introspectively would be better, but no one should say that a state is conscious only if its subject actively introspects it.). N.b., this usage is only one among several quite different though of course (...) not competing ones; the phrase has been used in at least two other senses, as by, respectively, Dretske (1993, 1995) and Block (1995).1 My definition is stipulative, but not brutely so; it settles on one thing that is often meant by conscious state cf. a conscious memory, a conscious desire, a conscious intention, a conscious decision. According to higher-order (HO) theories of consciousness in this sense of consciousness, what makes a mental state a conscious one is that it is represented by another of the subject’s mental states, that in virtue of which s/he is aware of it. Some practitioners follow Locke in taking the higher-order state to be quasi-perceptual (Armstrong, 1968, 1980, Lycan 1991, 1996); others say it may be merely a thought about the original state (Rosenthal, 1986, 1990).2 There is an alleged objection to such theories, that originated with Goldman (1993)Error: Illegal entry in bfrange block in ToUnicode CMapError: Illegal entry in bfrange block in ToUnicode CMapError: Illegal entry in bfrange block in ToUnicode CMap3 and has since been voiced and discussed by others (Dretske 1995, Stubenberg 1998, Van Gulick 2000, 2005, Gennaro 2005, Kriegel 2009).

Van Lambalgen's Theorem plays an important role in algorithmic randomness, especially when studying relative randomness. In this paper we extend van Lambalgen's Theorem by considering the join of infinitely many reals which are random relative to each other. In addition, we study computability of the reals in the range of Omega operators. It is known that $\Omega^{\phi'}$ is high. We extend this result to that $\Omega^{\phi^{(n)}}$ is $\textrm{high}_n$ . We also prove that there exists A such that, for each n (...) , the real $\Omega^A_M$ is $\textrm{high}_n$ for some universal Turing machine M by using the extended van Lambalgen's Theorem. (shrink)
According to Dr. Clare Graves, mankind has developed eight core value systems,1 as responses to prevailing circumstances. Given different contexts and value systems, a one-solution-fits-all concept of corporate sustainability is not reasonable. Therefore, this paper presents various definitions and forms of sustainability, each linked to specific (societal) circumstances and related value systems. A sustainability matrix– an essential element of the overall European Corporate Sustainability Framework – is described showing six types of organizations at different developmental stages, with different forms of (...) corporate sustainability, each supported by specific institutional arrangements.

The European Corporate Sustainability Framework (ECSF) is a new generation management framework, aimed to meet increased corporate complexity and support corporate transformation towards more sustainable ways of doing business. It is a multi-layer, integral business framework with an analytical, contextual, situational and dynamic dimension.Analytically, the framework is structured according to four focus points – the constitutional, conceptual, behavioural and evaluative perspective – providing integrative designs of complex and dynamic phenomena. The framework includes coherent sets of business philosophies, approaches, concepts and (...) tools that structures corporate realities and generates sequences of steps in order to obtain adequate institutional structures, a road to corporate transformation and higher performance levels.

In addition to the traditional personnel and human resource management (HRM), there is a need for a new approach to personnel management, which we will call Human Capital Management (HCM). HCM emphasises an alignment between the individual and the organization and in our view offers the challenge and the key to successful management in the future.
Over the past years, in books and journals (this journal included), N. Maxwell launched a ferocious attack on B. C. van Fraassen’s view of science called Constructive Empiricism (CE). This attack has been totally ignored. Must we conclude from this silence that no defence is possible and that a fortiori Maxwell has buried CE once and for all? Or is the attack too obviously flawed as not to merit exposure? A careful dissection of Maxwell’s reasoning will make it clear that (...) neither is the case. This dissection includes an analysis of Maxwell’s ‘aberrance–argument’ (omnipresent in his many writings) for the claim that science implicitly and permanently accepts a substantial, metaphysical thesis about the universe, which then paves the way for his own metaphysical-realist hierarchy-view of science. This aberrance-claim, which Maxwell directs against a widely shared and harmful ideology of science called ‘Standard Empiricism’, generally has been ignored too, for more than a quarter of a century. Our conclusions will be that (i) Maxwell’s attacks on CE can be beaten off, and (ii) his ‘aberrance–arguments’ do not establish what Maxwell believes they establish, but (iii) we can draw a number of valuable lessons from these attacks about the nature of science and of the libertarian nature of CE.

Traditionally, conceptualizations of human values are based on the assumption that individuals possess a single integrated value system comprising those values that people are attracted by and strive for. Recently, however, van Quaquebeke et al. (in J Bus Ethics 93:293–305, 2010 ) proposed that a value system might consist of two largely independent value orientations—an orientation of ideal values and an orientation of counter-ideal values (values that individuals are repelled by), and that both orientations exhibit antithetic effects on people’s responses (...) to the social world. Following a call for further research on this distinction, we conducted two studies to assess the independent effects of ideal and counter-ideal values in leadership settings. Study 1 ( N = 131) finds both value orientations to explain unique variance in followers’ vertical respect for their leaders. Study 2 ( N = 136) confirms these results and additionally shows an analogous effect for followers’ identification with their leaders. Most importantly, we find that both value orientations exhibit their effects only independently when the content of the two orientations pertain to different value types in Schwartz’s (in J Soc Issues 50:19–46, 1994 ) circumplex model. Implications for theory and practice are discussed. (shrink)

Virtue ethics is now well established as a substantive, independent normative theory. It was not always so. The revival of virtue ethics was initially spurred by influential criticisms of other normative theories, especially those made by Elizabeth Anscombe, Philippa Foot, John McDowell, Alasdair MacIntyre, and Bernard Williams. 1 Because of this heritage, virtue ethics is often associated with anti-theory movements in ethics and more recently, moral particularism. There are, however, quite a few different approaches to ethics that can reasonably claim (...) to be versions of virtue ethics. The predominant strand of virtue ethics is broadly Aristotelian, although some accounts bear little resemblance to Aristotle's. In its most general form, virtue ethics is compatible with a wide range of meta-ethical and normative commitments. This diversity makes it difficult to compare virtue ethics as such with other normative theories. It can also be a challenge to see just what the various versions of virtue ethics have in common with each other. Three major types of virtue ethics are represented in the books by Rosalind Hursthouse, Michael Slote, and Christine Swanton, recommended in the following section. Each of these book sets forward a considerably self-standing form of virtue ethics. The authors differ on central issues such as the relationship between virtue and flourishing and the link between virtuous agents and right or virtuous actions. Unlike Swanton and Slote, Hursthouse defends a version of ethical naturalism that has affinities with theories recently defended by Philippa Foot and Alasdair MacIntyre. 2 Slote's theory is agent-based, meaning that his account derives judgments about the moral status of actions from moral features of agents. Hursthouse and Swanton defend theories according to which the moral status of an action depends on its broader relationship to human flourishing (Hursthouse) or whether it hits the target of a virtue (Swanton). Although these three books presently form the core of contemporary virtue ethics, there are other approaches that might reasonably be described as versions of virtue ethics, such as those presented by Julia Driver, Linda Zagzebski, and Robert Adams. 3 There are also, of course, a large number of articles in which authors defend or criticize tenets that are central to most versions of virtue ethics. Some recent articles on especially important topics are listed in the following section. Current 'hot topics' in virtue ethics include whether its account of right action is adequate and whether virtue ethics is at odds with empirical psychology. Articles on these debates and others are listed in the following section. Author Recommends: Books These three books are foundational works in contemporary virtue ethics, and represent quite different approaches to virtue ethics. For each book, I have also listed an article by the same author in which he or she articulates some similar themes. Those pressed for time or space on a syllabus might start by examining those articles. 1. Hursthouse, Rosalind. On Virtue Ethics. Oxford: Oxford University Press, 1999. Hursthouse defends a eudaimonistic version of virtue ethics with Aristotelian affinities. *See also Hursthouse, Rosalind. 'Normative Virtue Ethics.' How Should One Live? Ed. Roger Crisp. Oxford: Clarendon Press, 1996. 19–36. 2. Slote, Michael. Morals from Motives. Oxford: Oxford University Press, 2001. Slote defends a version of virtue ethics based on evaluations of motives, drawing on historical figures like Martineau, Hutcheson, and Hume. Note that this book represents a fairly significant departure from his first book in virtue ethics, From Morality to Virtue (New York: Oxford, 1992). *See also Slote, Michael. 'Agent-Based Virtue Ethics.' Virtue Ethics . Ed. Roger Crisp and Michael Slote. Oxford: Oxford University Press, 1997. 3. Swanton, Christine. Virtue Ethics: A Pluralistic View. Oxford: Oxford University Press, 2003. Swanton defends a pluralistic, non-eudaimonistic version of virtue ethics that draws on influences ranging from Aristotle to Nietzsche to contemporary psychoanalytic theory. *See also Swanton, Christine. 'A Virtue Ethical Account of Right Action.' Ethics 112 (2001): 32–52. Articles The following is a selection of articles that address some of the central and controversial topics within virtue ethics. 1. Annas, Julia. 'Being Virtuous and Doing the Right Thing.' Proceedings and Addresses of the American Philosophical Association 78.2 (2004): 61–75. This article addresses the problem of action guidance and the role that an account of right action should play in virtue ethics. 2. Conly, Sarah. 'Flourishing and the Failure of the Ethics of Virtue.' Midwest Studies in Philosophy Vol. XIII, Ethical Theory: Character and Virtue . Eds. P. French et al. South Bend: University of Notre Dame Press, 1988. 83–96. This article articulates the central problems faced by versions of virtue ethics that rely on a conception of human flourishing. 3. Das, Ramon. 'Virtue Ethics and Right Action.' Australasian Journal of Philosophy 81 (2003): 324–39. This article raises objections about insularity and circularity to accounts of right action presented by Hursthouse, Slote, and Swanton. 4. Doris, John M. 'Persons, Situations, and Virtue Ethics.' Nous 32 (1998): 504–30. This article argues that situationist psychology undermines the concept of a character trait on which virtue ethicists rely. An expanded version of this criticism can be found in Doris, Lack of Character, Cambridge: Cambridge University Press, 2002. 5. Hursthouse, Rosalind. 'Virtue Theory and Abortion.' Philosophy and Public Affairs 20.3 (1991): 223–46. This article argues that virtue ethics is capable of providing action guidance in the difficult problem of abortion. 6. Johnson, Robert N. 'Virtue and Right.' Ethics 113 (2003): 810–34. This article raises several objections against the accounts of right action in virtue ethics, one of which is that they cannot make sense of the rightness of self-improving actions. The criticism is directly primarily at Hursthouse's theory, but Swanton and Slote are discussed as well. 7. Kamtekar, Rachana. 'Situationism and Virtue Ethics on the Content of Our Character.' Ethics 114 (2004): 458–91. This article argues that situationist critiques of virtue ethics rely on a mistaken understanding of virtuous character. 8. Kawall, Jason. 'Virtue Theory and Ideal Observers.' Philosophical Studies 109 (2002): 197– 222. This article argues for an ideal observer-style account of right action in virtue ethics. 9. Nussbaum, Martha. 'Non-Relative Virtues: An Aristotelian Approach.' Midwest Studies in Philosophy, Vol. XIII, Ethical Theory: Character and Virtue . Ed. P. French et al. South Bend: University of Notre Dame Press, 1988. 32–53. This article presents a view of the virtues on which the virtues are excellences in spheres of activity. Although the spheres are common to all humans, the manifestation of excellence in a given sphere is subject to cultural variation. 10. Sreenivasan, Gopal. 'Errors about Errors: Virtue Theory and Trait Attribution.' Mind 111 (2002): 47–68. This article addresses the situationist critique of character traits by arguing that virtue ethics does not depend on the concept of a character trait as Doris and others understand it. 11. Stangl, Rebecca. 'A Dilemma for Particularist Virtue Ethics.' Philosophical Quarterly 58 (2008): 665–78. This article addresses the relationship between virtue ethics and radical moral particularism, arguing that the latter may have undesirable consequences for virtue ethicists unless they accept the unity of the virtues. 12. Stohr, Karen. 'Contemporary Virtue Ethics.' Philosophy Compass 1.1 (January 2006): 22–7. This article provides an overview and analysis of contemporary virtue ethics. It includes discussion of main problems and challenges for the future. 13. Stohr, Karen. 'Moral Cacophony: When Continence is a Virtue.' Journal of Ethics 7 (2003): 339–63. This article raises problems for the commonly accepted distinction between virtue and continence, arguing that the mixed emotions normally associated with continence are sometimes characteristic of virtue instead. 14. van Zyl, Liezl. 'Agent-Based Virtue Ethics and the Problem of Action Guidance.' Journal of Moral Philosophy 6 (2009): 50–69. This article defends agent-based virtue ethics against objections that it cannot distinguish agent-appraisal from act-appraisal and that it cannot provide adequate action guidance. Anthologies 1. Crisp, Roger, ed. How Should One Live? Essays on the Virtues. Oxford: Clarendon Press, 1996. This is one of the first virtue ethics anthologies published, and so reflects a correspondingly earlier picture of the field. The essays, however, are important and interesting in their own right, and cover a broad array of topics. 2. Crisp, Roger and Michael Slote, eds. Virtue Ethics . Oxford: Oxford University Press, 1997. This anthology was published over a decade ago and does not capture recent developments in the field. It is, however, an admirably thorough collection of the most influential essays from the early days of virtue ethics, both promoting and criticizing it. 3. Darwall, Stephen, ed. Virtue Ethics. Oxford: Blackwell, 2003. This anthology is distinctive in that it includes material from Aristotle, Hutcheson, and Hume, along with some central contemporary sources. 4. Walker, Rebecca L. and Philip J. Ivanhoe, eds. Working Virtue. Oxford: Oxford University Press, 2007. This recent anthology focuses on applied virtue ethics and has an excellent selection of essays by influential thinkers on topics including the environment, business, medicine, war, and poverty.

In three experiments, we investigated the computational complexity of German reciprocal sentences with different quantificational antecedents. Building upon the tractable cognition thesis (van Rooij, 2008) and its application to the verification of quantifiers (Szymanik, 2010) we predicted complexity differences among these sentences. Reciprocals with all-antecedents are expected to preferably receive a strong interpretation (Dalrymple et al., 1998), but reciprocals with proportional or numerical quantifier antecedents should be interpreted weakly. Experiment 1, where participants completed pictures according to their preferred interpretation, provides (...) evidence for these predictions. Experiment 2 was a picture verification task. The results show that the strong interpretation was in fact possible for tractable all but one-reciprocals, but not for exactly n. The last experiment manipulated monotonicity of the quantifier antecedents. (shrink)

Quine is one of the most influential of contemporary philosophers, whose work has ranged broadly across a great number of topics and issues in a career spanning some fifty years. In this collection a group of distinguished philosophers offer a sustained critical evaluation of the full range of Quine's writings. Amongst the topics addressed are interpretation, epistemology, ontology, modality, and mathematical truth. This is very much a 'state of the art' collection that will influence all future discussion of Quine. The (...) contributors include: George Boolos, H-N. Castaneda, Donald Davidson, Umberto Eco, Dagfinn Follesdal, James Higginbotham, Charles Parsons, Hilary Putnam, Barry Stroud, and Bas van Fraassen.

In this article, I examine the ramified-type theory set out in the first edition of Russell and Whitehead's Principia Mathematica. My starting point is the ?no loss of generality? problem: Russell, in the Introduction (Russell, B. and Whitehead, A. N. 1910. Principia Mathematica, Volume I, 1st ed., Cambridge: Cambridge University Press, pp. 53?54), says that one can account for all propositional functions using predicative variables only, that is, dismissing non-predicative variables. That claim is not self-evident at all, hence a problem. (...) The purpose of this article is to clarify Russell's claim and to solve the ?no loss of generality? problem. I first remark that the hierarchy of propositional functions calls for a fine-grained conception of ramified types as propositional forms (?ramif-types?). Then, comparing different important interpretations of Principia?s theory of types, I consider the question as to whether Principia allows for non-predicative propositional functions and variables thereof. I explain how the distinction between the formal system of the theory, on the one hand, and its realizations in different epistemic universes, on the other hand, makes it possible to give us a more satisfactory answer to that question than those given by previous commentators, and, as a consequence, to solve the ?no loss of generality? problem. The solution consists in a substitutional semantics for non-predicative variables and non-predicative complex terms, based on an epistemic understanding of the order component of ramified types. The rest of the article then develops that epistemic understanding, adding an original epistemic model theory to the formal system of types. This shows that the universality sought by Russell for logic does not preclude semantical considerations, contrary to what van Heijenoort and Hintikka have claimed. (shrink)

It has become a standard view in the philosophy of science scholarship (e.g., van Fraassen [1989]) that debates on the problem of laws of nature and/or scientific laws employ pre-Kantian approaches to the subject in question. But what exactly a Kantian approach might look like and, above all, what Kant endorses on this matter are not entirely settled issues. In particular, this regards Kant’s argument on the problem of ’necessity grounding’ with respect to different types of the so-called “empirical laws (...) of nature” (empirische Naturgesetze) in the third Critique. In order to assess the aforementioned problem, in this paper I will address the following questions:1) What is Kant’s main nomological criterion or a combination of criteria, that is, the criterion/criteria according to which we can explicate the distinction between laws of nature and accidentally true statements?2) What exactly is the role of an apriori law of nature, such as the one instantiated by the Second Analogy of Experience, in considering nature as a lawful existence of objects?3) On what grounds can a statement describing a particular causal regularity, for example, the statement “the sun warms the stone” (Prolegomena, N 301), be viewed as an empirical law of nature?4) Is Kant’s systematicity a nomological criterion in the strict and standard sense or, rather, is it a certain kind of transcendental criterion, which not only makes the whole of Kant’s nomological machinery up and running, but also has decisive influence on the final arrangement of nomological criteria?

L. van den Dries proved that the theory of n-valued rings has a model companion. We show here that this result is still true when the valuation rings are required to satisfy given inclusion relations (we restrict ourselves to the case of residual characteristic zero).
The objective of this paper is to discuss current reductive theories of the non-existent objects, specifically - contemporary deflationary theories of the fictional objects. By such theories I mean those denying that fictional objects have any ontological status at all. Theories, which claim that fictional proper names denote some sort of objects but deny that these names denote individual objects, are treated as the reductive theories of non-existent as well. In the discourse I present the following ideas: 1) Russell's theory (...) of description with the further remarks by W. V. O. Quine; 2) A. Plantinga's view that the fictional names have no denotation, which is realized in the framework of possible worlds semantics; 3) Theories by N. Wolterstorf and P. van Inwagen which can be seen as a link between strictly deflationary theories and meinongian theories; Wolterstorff claim that empty names denote general abstract objects and Inwagen identify fictional objects with theoretical objects of literal criticism; 4) Theories based on the speech acts theories; 5) Theories which identify fictional objects with mental objects. The conclusion of the argument is that the aforementioned theories are not adequate for the analysis of fiction (non-existent) and that more suitable for such a purpose are meinongian theories of non-existent objects.

En la gran producció filosòfica d?Eusebi Colomer, s?hi poden distingir tres grans centres d?interès particularment destacats. En primer lloc, la seva dedicació a l?estudi del pensament de Ramon Llull i de Nicolau de Cusa. La seva tesi doctoral va mostrar les influències lul·lianes en l?obra de Nicolau de Cusa a partir de les anotacions autògrafes en què el jove Nicolau es feia ressò de les coses que més li interessaven de Llull. El segon gran centre d?interès el van constituir, naturalment, (...) els grans corrents de la filosofia alemanya moderna i contemporània. Des dels anys d?estudiant s?havia familiaritzat particularment amb l?idealisme, la fenomenologia i la filosofia de l?existència. Finalment, el seu tercer centre d?interès va ser el diàleg filosòfico-teològic. Colomer lamentava profundament el divorci produït entre la filosofia i la teologia. Adaptant una coneguda formulació de Kant, pensava que la teologia sense filosofia és cega, però que la filosofia sense teologia és buida. Format en la tradició metafísica espiritualista i defensor de l?humanisme cristià, Colomer es trobava, però, a les antípodes de qualsevol sectarisme o dogmatisme. La seva formació, el seu tarannà i, segurament, els seus enormes coneixements de la història de la filosofia, li havien conferit una gran capacitat per al diàleg. Ell no veia el diàleg com un recurs o com una tàctica, sinó com un element constitutiu de l?ésser humà. \n. (shrink)
This paper considers two “mysteries” having to do with vagueness. The first pertains to existence. An argument is presented for the following conclusion: there are possible cases in which ‘There exists something that is F’ is of indeterminate truth-value and with respect to which it is not assertable that there are borderline-cases of “being F.” It is contended that we have no conception of vagueness that makes this result intelligible. The second mystery has to do with “ordinary” vague predicates, such (...) as ‘tall’. An argument is presented for the conclusion that although there are people who are “tall to degree 1”—definitely tall, tall without qualification—, no greatest lower bound can be assigned to the set of numbers n such that a man who is n centimeters tall is tall to degree 1. But, since this set is bounded from below, this result seems to contradict a well-known property of the real numbers. (shrink)
An inequality in quantum mechanics, which does not appear to be well known, is derived by elementary means and shown to be quite useful. The inequality applies to 'all' operators and 'all' pairs of quantum states, including mixed states. It generalizes the rule of the orthogonality of eigenvectors for distinct eigenvalues and is shown to imply all the Robertson generalized uncertainty relations. It severely constrains the difference between probabilities obtained from 'close' quantum states and the different responses they can have (...) to unitary transformations. Thus, it is dubbed a master inequality. With appropriate definitions the inequality also holds throughout general probability theory and appears not to be well known there either. That classical inequality is obtained here in an appendix. The quantum inequality can be obtained from the classical version but a more direct quantum approach is employed here. A similar but weaker classical inequality has been reported by Uffink and van Lith. (shrink)
Marc Alspector-Kelly claims that Bas van Fraassen’s primary challenge to the scientific realist is for the realist to find a way to justify the use of some mode of inference that takes him from the world of observables to knowledge of the world of unobservables without thereby abandoning empiricism. It is argued that any effort to justify such an “inferential wand” must appeal either to synthetic a priori or synthetic a posteriori knowledge. This disjunction turns into a dilemma for the (...) empirically-minded realist as either disjunct leads to unwanted consequences. In this paper, I split the horns of this dilemma by arguing that the realist can justify one particular such mode of inference – abduction – without committing himself to rationalism. The realist may justify this mode of inference by appealing to the analytic a priori axioms of the probability calculus. I show that Peter Lipton’s tripartite defense of abduction constitutes such a method of justification. (shrink)
In an earlier paper I identified two desiderata of a theory of practical reasons which favour internalism, and then argued that forms of this doctrine which are currently on offer lose either one or the other in trying to avoid the conditional fallacy. Michael Brady, Mark van Roojen and Josh Gert have separately attempted to respond to my argument. I set out reasons why all fail.
This study provides an additional partial test of the Hunt–Vitell theory [1986, Journal of Macromarketing, 8, 5–16; 1993, ‘The General Theory of Marketing Ethics: A Retrospective and Revision’, in N. C. Smith and J. A. Quelch (eds.), Ethics in Marketing (Irwin Inc., Homewood), pp. 775–784], within the consumer ethics context. Using structural equation modeling, the relationships among an individual’s personal values (conceptualized by the typology of Schwartz [1992, ‘Universals in the Content and Structure of Values: Theoretical Advances and Empirical (...) Tests in 20 Countries’, in M. P. Zanna (ed.), Advances in Experimental Social Psychology (Vol. 25, Academic Press, Orlando), pp. 1–65] ethical ideology and ethical beliefs are investigated. The validity of the model is assessed in a two-step procedure. First, a measurement model of constructs is tested for key validity dimensions. Next, the hypothesized causal relationships are examined in several path models, comparing no mediation, partial and complete mediation of ethical ideology. The empirical results indicate that individual differences in value priorities (resultant conservation and resultant self-enhancement) directly and indirectly (through idealism) influence the judgment of ethically questionable consumer practices. These findings may significantly contribute to the theoretical understanding of ethical decision-making. (shrink)

Features are unary operators used to build record-like expressions. The resulting term algebras are encountered in linguistic computation and knowledge representation. We present a general description of feature logic and of a slightly restricted version, called record logic. It is shown that every first-order theory can be faithfully interpreted in a record logic with various additional axioms. This fact is used elsewhere [15] to extend a result of Tarski and Givant [14] on expressing first order theories in relation algebra.
The House Sparrow (Passer domesticus), formerly a common bird species, has shown a rapid decline in Western Europe over recent decades. In The Netherlands, its decline is apparent from 1990 onwards. Many causes for this decline have been suggested that all decrease the vital rates, i.e. survival and reproduction, but their actual impact remains unknown. Although the House Sparrow has been dominant in The Netherlands, data on life history characteristics for this bird species are scarce: data on reproduction are non-existent, (...) and here we first present survival estimates based on live encounters and dead recoveries of marked individuals over the period 1976–2003, 14 years before and 14 years during the decline, reported to the Dutch Ringing Centre. We show that there is an indication that both juvenile and adult survival are lower during the period of decline. Secondly, to be able to analyse the relative impact of changes in the vital rates, we formulated a general matrix model based on a range of survival values between zero and one with a step size of 0.01 (both juvenile and adult yearly survival) and a range of realistic reproduction values (one, three or five fledglings per pair per year). With the matrix model, we calculated the finite rate of population change (λ) and applied elasticity analysis. To diagnose the cause of the decline in the Dutch House Sparrow, we parameterised the model with estimates of survival values before and during the decline and present the resulting λ. With the survival estimates from the declining period, λ < 1 only if reproduction is relatively low. We discuss this result within the light of available literature data on survival in the House Sparrow. Finally, we evaluate which of the suggested causes of population decline should be reversed to mitigate the decline and how this can be achieved. (shrink)
Functions of type n are characteristic functions on n-ary relations. Keenan [5] established their importance for natural language semantics, by showing that natural language has many examples of irreducible type n functions, i.e., functions of type n that cannot be represented as compositions of unary functions. Keenan proposed some tests for reducibility, and Dekker [3] improved on these by proposing an invariance condition that characterizes the functions with a reducible counterpart with the same behaviour on product relations. The present paper (...) generalizes the notion of reducibility (a quantifier is reducible if it can be represented as a composition of quantifiers of lesser, but not necessarily unary, types), proposes a direct criterion for reducibility, and establishes a diamond theorem and a normal form theorem for reduction. These results are then used to show that every positive n function has a unique representation as a composition of positive irreducible functions, and to give an algorithm for finding this representation. With these formal tools it can be established that natural language has examples of n-ary quantificational expressions that cannot be reduced to any composition of quantifiers of lesser degree.

We show that van Lambalgen's Theorem fails with respect to recursive randomness and Schnorr randomness for some real in every high degree and provide a full characterization of the Turing degrees for which van Lambalgen's Theorem can fail with respect to Kurtz randomness.

Le culte grandiose de Kali, la Mère, son incomparable symbolisme, ses litanies et ses chants, embrasse l'âme de l'univers qu'il glorifie comme aucune conception religieuse ne le fit jamais. La terrifiante déesse sème la peste et les pires ravages sur ses pas, tout en accordant sa grâce et sa clémence à ses enfants assez hardis pour soulever l'horrible masque derrière lequel elle se cache la figure. Ceux-là retrouveront les traits radieux qui ont enchanté leur enfance. La sublime conception de Kali, (...) la Mère, découle d'une philosophie moniste qui s'écarte pourtant sensiblement de la philosophie Védanta de Shankara. Tous deux partent, il est vrai, de la même idée. Ils admettent l'un et l'autre une substance une, indivisible et éternelle, que les Védantins appellent Brahma et les adorateurs de Kali, la Mère, Siva. Mais il y a divergence quant aux manifestations. Pour Shankara il n'y a qu'illusion. Il tranche le lien qui rattache le phénomène à l'absolu. Il se demande qui a pu susciter l'apparence. Mais, l'absolu étant la vérité même, il n'a pu engendrer l'apparence pas plus que la lumière n'aurait pu engendrer l'obscurité. Qu'y avait-il donc de commun entre les Brahmas et Maya? A première vue il semble qu'il n'y a aucun rapport. Pour Shankara il n'était besoin d'aucune relation, puisque Maya n'existe pas en réalité et que le monde n'est que mirage. Le monde n'existe que pour l'esprit qui est lui-même sujet aux hallucinations. Adorer la Mère, c'est accepter l'univers dans ses aspects les plus terrifiants. Cette philosophie est diamétralement opposée au christianisme dans son culte du Dieu d'amour, du Père plein de miséricorde. Le christianisme enseigne que tout se fait pour notre bien, tandis que pour les adorateurs de Kali, l'univers est féroce et hostile à l'homme, qui avant tout doit se montrer supérieur aux événements. Mais Kali n'est pas seulement la destructrice. Si elle démolit inexorablement toutes les formes vitales qui ont fait leur temps et qui se détériorent, elle en crée au fur et à mesure des nouvelles. C'est dans cette conception de la Mère qu'il faut chercher tout d'abord le mystère de l'esprit indien. Dans son essence la plus intime la mère du monde est l'absolu, est Siva même. Comme telle elle représente la connaissance, l'entité et la joie absolues. Pour les adorateurs de Kali les mots Mantram Saham (je suis elle) renferment la clef de la vie et dissipent crainte et tristesse. (shrink)
This article provides a critical view on the development and deployment phase of the e-ID in Belgium since 1999. It is based on extensive desk research and fifteen in depth-interviews with experts and stakeholders from government, administration, academia and industry who have been key in the development of the e-ID. The article identifies different elements that influenced, both in a positive and negative way, the societal, technical and political aspects of the Belgian e-ID. It shows that no severe problems occurred (...) during the initial deployment phase, which came to an end in 2009 providing over eight million Belgian citizens with an e-ID. The pre-existence of a National Register and the preliminary experiences with the exchange of digital information between administrative entities in the field of Social Security enabled and facilitated the development and the distribution of the e-ID. However, the research also reveals that usage of the e-ID by citizens and uptake of e-ID based services by administration and business remains limited due to multiple factors. The complex system of state structures in Belgium and as a consequence the dispersion of competences across different governmental entities makes that no unified approach to e-government and e-ID based services has been developed. From the industries’ point of view the privacy framework and the strictly regulated use of the National Registration Number provides no clear view on the allowed use of data accessible through the e-ID hampering take up in this area.

These lecture notes were composed while teaching a class at Stanford and studying the work of Brian Chellas (Modal Logic: An Introduction, Cambridge: Cambridge University Press, 1980), Robert Goldblatt (Logics of Time and Computation, Stanford: CSLI, 1987), George Hughes and Max Cresswell (An Introduction to Modal Logic, London: Methuen, 1968; A Companion to Modal Logic, London: Methuen, 1984), and E. J. Lemmon (An Introduction to Modal Logic, Oxford: Blackwell, 1977). The Chellas text influenced me the most, though the order of (...) presentation is inspired more by Goldblatt.2 My goal was to write a text for dedicated undergraduates with no previous experience in modal logic. The text had to meet the following desiderata: (1) the level of difficulty should depend on how much the student tries to prove on his or her own—it should be an easy text for those who look up all the proofs in the appendix, yet more difficult for those who try to prove everything themselves; (2) philosophers (i.e., colleagues) with a basic training in logic should be able to work through the text on their own; (3) graduate students should find it useful in preparing for a graduate course in modal logic; (4) the text should prepare people for reading advanced texts in modal logic, such as Goldblatt, Chellas, Hughes and Cresswell, and van Benthem, and in particular, it should help the student to see what motivated the choices in these texts; (5) it should link the two conceptions of logic, namely, the conception of a logic as an axiom system (in which the set of theorems is constructed from the bottom up through proof sequences) and the conception of a logic as a set containing initial ‘axioms’ and closed under ‘rules of inference’ (in which the set of theorems is constructed from the top down, by carving out the logic from the set of all formulas as the smallest set closed under the rules); finally, (6) the pace for the presentation of the completeness theorems should be moderate—the text should be intermediate between Goldblatt and Chellas in this regard (in Goldblatt, the completeness proofs come too quickly for the undergraduate, whereas in Chellas, too many unrelated....

Going back at least to Duhem, there is a tradition of thinking that crucial experiments are impossible in science. I analyse Duhem's arguments and show that they are based on the excessively strong assumption that only deductive reasoning is permissible in experimental science. This opens the possibility that some principle of inductive inference could provide a sufficient reason for preferring one among a group of hypotheses on the basis of an appropriately controlled experiment. To be sure, there are analogues to (...) Duhem's problems that pertain to inductive inference. Using a famous experiment from the history of molecular biology as an example, I show that an experimentalist version of inference to the best explanation (IBE) does a better job in handling these problems than other accounts of scientific inference. Furthermore, I introduce a concept of experimental mechanism and show that it can guide inferences from data within an IBE-based framework for induction.

Scientific realism is a doctrine that was both in and out of fashion several times during the twentieth century. I begin by noting three presuppositions of a succinct characterization of scientific realism offered initially by the foremost critic in the latter part of the century, Bas van Fraassen. The first presupposition is that there is a fundamental distinction to be made between what is “empirical” and what is “theoretical”. The second presupposition is that a genuine scientific realism is committed to (...) their being “a literally true story of what the world is like”. The third presupposition is that there are methods for justifying a belief in the empirical adequacy of a theory which do not also suffice to justify beliefs in its literal truth. Each of these presuppositions raises a number of problems, some of which are quite old and others rather newer. In each case, I briefly review some of the old problems and then elaborate the newer problems. (shrink)
I defend the view that single experiments can provide a sufficient reason for preferring one among a group of hypotheses against the widely held belief that “crucial experiments” are impossible. My argument is based on the examination of a historical case from molecular biology, namely the Meselson-Stahl experiment. “The most beautiful experiment in biology”, as it is known, provided the first experimental evidence for the operation of a semi-conservative mechanism of DNA replication, as predicted by Watson and Crick in 1953. (...) I use a mechanistic account of explanation to show that this case is best construed as an inference to the best explanation (IBE). Furthermore, I show how such an account can deal with Duhem's well-known arguments against crucial experiments as well as Van Fraassen's “bad lot” argument against IBE. (shrink)
Research on work values shows that respectful leadership is highly desired by employees. On the applied side, however, the extant research does not offer many insights as to which concrete leadership behaviors are perceived by employees as indications of respectful leadership. Thus, to offer such insights, we collected and content analyzed employees’ narrations of encounters with respectful leadership ( N 1 = 426). The coding process resulted in 19 categories of respectful leadership spanning 149 leadership behaviors. Furthermore, to also harness (...) this comprehensive repertoire for quantitative organizational research, we undertook two more studies ( N 2a = 228; N 2b = 412) to empirically derive a feasible item-based measurement of respectful leadership and assess its psychometric qualities. In these studies, we additionally investigated the relationships between respectful leadership as assessed with this new measurement and employees’ vertical and contextual followership as assessed via subordinates’ identification with their leaders, their appraisal respect for their leaders, their feeling of self-determination, and their job satisfaction.

Van der Henst argues that the theory of mental models lacks a pragmatic component. He fills the gap with the notion that reasoners draw the most relevant conclusions.

In this paper, I argue that van Fraassen’s “bad lot objection” against Inference to the Best Explanation [IBE] severely misses its mark. First, I show that the objection holds no special relevance to IBE; if the bad lot objection poses a serious problem for IBE, then it poses a serious problem for any inference form whatever. Second, I argue that, thankfully, it does not pose a serious threat to any inference form. Rather, the objection misguidedly blames a form of inference (...) for not achieving what it never set out to achieve in the first place. (shrink)
The results of two independent empirical studies with Flemish citizens were combined to address the problem of a short fall of information provision about higher welfare products. The research objectives were (1) to improve our understanding of how citizens conceptualize farm animal welfare, (2) to analyze the variety in the claimed personal relevance of animal welfare in the food purchasing decision process, and (3) to find out people’s needs in relation to product information about animal welfare and the extent to (...) which the current information caters to these needs. The first study consisted of a survey conducted in three consecutive years (2000–2002, n = 521) and was complemented with more recent qualitative data from four focus group discussions (2006, n = 29). Citizens’ conceptualization of farm animal welfare matched reasonably well with those in the scientific literature, although it is clearly influenced by a lower level of practical experience and a higher weight of empathy. In general, respondents indicated that animal welfare was an important product attribute, although it was less important than primary product attributes such as quality, health, and safety. Moral issues, rather than a perception of higher quality, were the main influence on preferences for higher welfare products. At present, higher standards of animal welfare are mostly guaranteed within more general quality assurance schemes. Yet people’s decisions to not choose higher welfare products seems to be related to the perceptual disconnection between eating animal food products and the living producing animals. Respondents generally thought better information provision was required and the present level of provision was strongly criticized. In combination, the findings of both studies help inform the discussion about how citizens can be informed about animal welfare and the preferred content, source, and medium of such information . The paper also provides insights into citizens’ semantic interpretation of the concept of animal welfare ( what wordings they use ) and the range of relevance that animal welfare has for different groups that, in turn is useful in identifying which segments can be targeted. This can contribute to a more effective valorization of animal welfare as a product attribute. (shrink)

Several attempts to conceptualize farm animal welfare have been criticized for diverging reasons, among them often the failure to incorporate the public concern and opinion. This paper’s objective is to develop a conception of farm animal welfare that starts from the public’s perception and integrates the opinion of different stakeholder representatives, thus following a fork-to-farm approach. Four qualitative citizen focus group discussions were used to develop a quantitative questionnaire, which has been completed by a representative sample of Flemish citizens ( (...) n = 459). Exploratory and confirmatory factor analyses were applied to develop a conception of farm animal welfare starting from an extended list of aspects that relate to animal production and associate with farm animal welfare in the public’s perception. In depth interviews with stakeholder representatives were used to match and adapt the structure of the animal welfare conception model. The resulting conception revealed seven dimensions grouped in two different levels. Three dimensions were animal-based: “Suffering and Stress,” “Ability to Engage in Natural Behavior,” and “Animal Health.” Four dimensions were resource-based: “Housing and Barn climate,” “Transport and Slaughter,” “Feed and Water,” and “Human-Animal Relationship.” This conception is distinct from earlier attempts since it is based on public perceptions; it addresses the opinion of different stakeholders, and it distinguishes empirically between animal-based and resource-based dimensions in the conceptualization of farm animal welfare. The relevancy of a popular definition is supported by the present demand oriented economy, in which animal welfare is a non-trade concern, and mainly left to the market where consumers still mainly act as individuals who calculate and weigh pros and cons.

Inspired by the work of Richard Abel, the authors conduct a N=1 study into the career path and disciplinary records of a Dutch immigration advocate. Their aim is to offer explanations as to why some lawyers seem so impervious to discipline. The authors analyse the case from three different angles: (1) characteristics of the disciplinary system (2) the social network of the advocate in question, including his professional network, and (3) the advocate?s personality. According to the authors, the key to (...) explaining non-compliance with ethical rules lies in the interaction between these three perspectives. In the case of the immigration lawyer a lack of professional socialization and the fact that he operated on his own, without substantial feedback or criticism from his social network were important explanatory factors. The article also offers a detailed insight into the effects of an accelerated disciplinary proceeding in which a local bar president ex officio assumes a new role. (shrink)
