Unification grammars are known to be Turing-equivalent; given a grammar G and a word w, it is undecidable whether w L(G). In order to ensure decidability, several constraints on grammars, commonly known as off-line parsability (OLP), were suggested, such that the recognition problem is decidable for grammars which satisfy OLP. An open question is whether it is decidable if a given grammar satisfies OLP. In this paper we investigate various definitions of OLP and discuss their interrelations, proving that some of (...) the OLP variants are indeed undecidable. We then present a novel, decidable OLP constraint which is more liberal than the existing decidable ones. (shrink)

This work examines the relationship between the endings chosen for musical works based on the biblical story of Jephtah's daughter and broader currents of European thought. Because the biblical story leaves the fate of Jephtah's daughter unclear, commentators have offered two interpretations: Jephtah's daughter is either sacrificed or consecrated to God. The examination of these two interpretations in the various commentaries and artistic works throughout the ages suggest a possible correlation between a given artist's religious affiliation and the type of (...) ending he composed for the story. Although Catholics would appear more likely to choose consecration as promoting the ideal of women's celibacy, no such correlation is seen in practice. Rather, the determining factor in the choice of the musical ending of the story is the dominant artistic convention of the time. This finding is in line with Curt Sachs's cultural theory of a universal pendulum of styles in Western civilization. Thus, the specific choice of the ending of the story of Jephtah's daughter in various artistic media may serve as a paradigm for broader trends of European thought. (shrink)

Through a combination of a controlled experiment and a survey, we examine the effect of voting power on shareholders’ voting behavior at general meetings. To avoid a selection bias, common in archival voting data, we exogenously manipulate shareholders’ power to affect the outcome. Our findings suggest that, when it comes to corporate decisions involving conflicts of interest, voting power nudges shareholders to oppose management and to choose the “right” alternative, that is, vote against a proposal which _prima facie_ does not (...) serve the company’s best interest. This effect obtained even when the dissenting vote contravened the choices of all other voters. Furthermore, the drive “to do the right thing” was established as significant, above and beyond the size of the economic stake. We also demonstrate that strategic voting among institutional investors is contingent on voting power: when in a position to affect the outcome of a vote, institutional investors tend to eschew strategic considerations and display fewer consistent patterns in their voting, compared to situations in which their ability to make a difference is limited. In anticipation of a “bad” proposal to be put to vote at the general shareholder meeting, institutional investors prefer to negotiate terms with management beforehand, and vote against it only after such negotiations fail. Our results shed new light on the “behind the scenes” processes in shareholder voting and underscore the importance of institutional investor agency to corporate governance, accountability, and minority shareholder representation.

I hated my outpatient primary care clinic during residency. Every Wednesday at noon, I scrambled to finish my inpatient work in the hospital, to raggedly see my patients, to sign out my unfinished errands to the covering residents, and to leave the children’s hospital, heading north up the dilapidated thoroughfare to the federally qualified health center where my residency clinic was held. The noise of the street, the honking of the cars, the shouts of the pedestrians, the extremes of cold (...) and of heat: after hiding in the sanctity of the university, the five-minute march up to clinic immersed me in the battlefield of the South Side of Chicago. The march prepared me for the chaos that awaited me in the... (shrink)

L'interrogation sur le rôle que jouent aujourd'hui les convictions religieuses en philosophie des sciences peut paraître une démarche surprenante, car trop souvent la religion est rejetée hors du champ de l'enquête philosophique. Cet ouvrage ose au contraire demander dans quelle mesure les options religieuses d'un penseur influencent sa conception de l'ordre cosmique. L'examen du concept de loi de la nature s'inscrit dans une quête plus large : il permet de tester la façon dont les choix épistémologiques d'un individu dépendent de (...) sa vision du monde et ainsi de porter une attention particulière aux interactions entre science, épistémologie et religion. L'étude porte sur quatre figures des plus marquantes du débat contemporain sur les lois de la nature : David Armstrong, Nancy Cartwright, David Lewis et Bas van Fraassen. L'analyse de leurs écrits, approfondie d'entretiens personnels, fait ressortir pour chacun les liens qui existent entre sa posture religieuse et son compte rendu de la légalité naturelle. (shrink)

La figure de l’entrepreneur est aujourd’hui utilisée dans une grande variété de discours publics. Ce travail cherche à remonter à l’une des sources théoriques de la constitution de cette figure : la théorie de l’entrepreneur de Schumpeter (1911a et 1911b). Ce retour montre que Schumpeter, dans son contexte intellectuel et théorique, est amené à importer une anthropologie philosophique en économie, celle de Nietzsche, auteur largement lu dans l’Autriche du début du xxe siècle. En transposant, à l’intérieur de sa théorie économique, (...) certaines caractéristiques majeures du grand homme créatif nietzschéen dans la figure de l’entrepreneur, Schumpeter développe une explication originale de la nature dynamique du marché et de l’évolution économique. Néanmoins il importe aussi de Nietzsche une série d’ambiguïtés, notamment en ce qui concerne l’origine de l’exceptionnalité individuelle de l’entrepreneur, et plus particulièrement de sa puissance créatrice. Une seconde ambiguïté est très largement héritée, qui concerne l’extension du modèle de l’individu entrepreneur : constitue-t-il une théorie de l’action valable pour tous les individus ou uniquement pour un type d’individus particuliers? Comment concilier exceptionnalité de l’entrepreneur et norme d’un entreprenariat pour tous? La dernière partie de ce travail s’attache ainsi à explorer ces ambiguïtés, qui apparaissent chez Schumpeter et ses successeurs, notamment Israël Kirzner.Codes JEL : B13, B25, B31, B40. (shrink)

Beginning with a critical examination of the humanist assumptions of critical ethnography, this article interrogates and surfaces problems with the ontological and epistemological orientations of this research methodology. In drawing on exemplar empirical data from an arts‐based project, the article demonstrates the limitations in the humanist‐based qualitative research approach and advances a postdualist, postrepresentationalist direction for critical ethnography called entangled ethnography. Using data from a larger study that examined the perspectives of racialized mad artists, what is demonstrated in this inquiry (...) is that the entanglement of bodies, objects, and meaning‐making practices is central to working with the ontologically excluded, such as those who find themselves in various states of disembodiment and/or corporeal and psychic distribution. We propose the redevelopment of critical ethnography, extended by entanglement theory (a critical posthuman theory), and suggest that for it to be an inclusive methodology, critical ethnography must be conceptualized as in the process of becoming and always in regeneration, open to critique, extension, and redevelopment.

Historically, individuals who file for bankruptcy protection have been viewed harshly by society. The negative perception of bankrupts was manifested in the punitive measures employed against bankruptcy petitioners, in the degrading public rituals directed at them, and in the contemptuous discourse used by officials to refer to the bankrupts. This traditional negative image of bankrupts was shared in colonial America, and vigorously continued throughout the Victorian era and into the 20th century. By the 1960s, a number of critics began to (...) voice their concerns about the dramatic rise in consumer bankruptcy filings in the United States. The critics have mostly attributed the increase in filings to an alleged decline both in morals and in the shame associated with bankruptcy. Charges of the fading stigma of bankruptcy have recently intensified. A number of recent studies have attempted to corroborate assertions of the declining stigma of bankruptcy through the use of indirect variables as proxies. These attempts to measure bankruptcy stigma have been roundly criticized. The disapproval centers mainly on the studies’ failure to directly measure changes in public perception of bankruptcy. This study attempts to measure the evolution of stigma in bankruptcy by addressing the methodological concerns attributed to previous empirical studies on this subject. Rather than measuring bankruptcy stigma through the examination of indirect bankruptcy stigma proxies or through the questioning of former petitioners, this study measures evolving public perceptions about bankruptcy by examining the expressed sentiments of the general public. To ascertain whether the negative image of bankrupts has eroded in the United States over the past century and a half, 171 newspaper articles published between 1864 and 2002 about personal bankruptcy were examined for content. Examination of the content of personal bankruptcy related newspaper articles provides valuable information about the evolution of public perceptions of bankrupts during that period. This study detected a noticeable shift, beginning in the 1960s, in public attitudes towards individuals filing for personal bankruptcy. However, it did not find that the changing public perception necessarily prompted an increase in the bankruptcy filings. (shrink)

Recent work in quantum information science has produced a revolution in our understanding of quantum entanglement. Scientists now view entanglement as a physical resource with many important applications. These range from quantum computers, which would be able to compute exponentially faster than classical computers, to quantum cryptographic techniques, which could provide unbreakable codes for the transfer of secret information over public channels. These important advances in the study of quantum entanglement and information touch on deep foundational issues in both physics (...) and philosophy. This interdisciplinary volume brings together fourteen of the world's leading physicists and philosophers of physics to address the most important developments and debates in this exciting area of research. It offers a broad spectrum of approaches to resolving deep foundational challenges - philosophical, mathematical, and physical - raised by quantum information, quantum processing, and entanglement. This book is ideal for historians, philosophers of science and physicists"--Provided by publisher. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy, Psychiatry, & Psychology 10.3 (2003) 227-231 [Access article in PDF] World Traveling as a Clinical Methodology for Psychiatric Care Suzanne M. Jaeger Keywords embodiment, dialogical consciousness, interpersonal communication, epistemic responsibility, self-knowledge, understanding IN HER ARTICLE "Moral Tourists and World Travelers," Nancy Potter suggests a way in which psychiatrists and psychologists could gain a better understanding of their mentally ill patients' experiences. Rather than assuming that hallucinations and (...) incoherent speech and behavior are merely senseless disconnections from reality, Potter argues that mental health care clinicians ought to spend time engaging patients on their own terms. Even when mental illness is a result of brain disease, much can be learned about the patient's experiences of their disease by temporarily setting aside the scientific frameworks of diagnosis and medical treatment. Potter uses Maria Lugones' concept of world traveling and recommends playfully accepting, and even entering into the patient's world (Lugones 1990). She calls world traveling a methodology and explains it in some detail. Moreover, at the close of her essay, Potter suggests that clinicians have a moral obligation to understand the mentally ill patient's world from the patient's perspective. This obligation is based on an appeal to our sense of what it is to be a responsible knower who attends to issues of trust and truth. Relying on arguments made by Lorraine Code (1987), Potter asserts that to try to understand the other's perspective is the responsible thing to do.My discussion focuses on the notion of play to which Potter appeals, as well as on what she sees as the moral obligation of clinicians to communicate with their mentally ill patients in extra-professional ways. This moral obligation arises because (a) the theoretical and professional frameworks of medical science are seen as inadequate, and (b) playfulness opens up mutually respectful, authentic interaction between persons. I generally agree with Potter's claims, and I want to situate them in the wider framework of an epistemological debate about the status of our knowledge of others. A broader context will help to elucidate the strengths of Potter's analysis as well as some points for critical discussion. I begin with the relationship of trust between clinicians and patients.Few people would disagree with the claim that patients need to be able to trust that their physicians are not harming them, but helping them to get better. If patients feel misunderstood, they will not trust their caretakers. This is probably even truer for psychiatric patients, whose conditions and loss of autonomy make establishing trust even more challenging. Psychiatric patients [End Page 227] often have their own ways of compensating for the symptoms of their mental illness. If either their will to survive or their compensatory strategies go unrecognized or misinterpreted, patients may respond by rejecting the well-intentioned efforts of caretakers to restore them to a degree of ease, measured as it must be by the standards of the professionals under whose care the patient remains. 1 Despite the fact that these standards are established through scientific testing procedures for the treatment of diseases, they may be experienced by patients as indifferent to the particular and unique features of their condition. Nestled within the issue of trust is thus a question of truth.Although current scientific knowledge of the human brain, and of human behavior, has made available a range of sophisticated therapies and psychotropic drugs, there are still many mental illnesses that leave families and clinicians wondering whether the treatment plans are providing any help. Alzheimer's disease and schizophrenia are two examples. There is a difference between, on the one hand, containing the patient's behavior by admitting the patient to a psychiatric ward and managing symptoms with psychotropic medications, and, on the other hand, understanding what is happening for the patient, from his or her perspective. Although psychiatric patients may not have a realistic sense of either their abilities or the extent and nature of their disease, there may be much about their experiences that ought to be known and understood by the professionals caring for them...

In lieu of an abstract, here is a brief excerpt of the content:The Truth about Narrative, Or:How Does Narrative Matter?Ruth Ronen and Efrat BibermanIn the summer of 1898, a sixteen-year-old girl, intelligent and good looking, entered Freud's clinic in Vienna. The girl, whom Freud would call Dora, suffered recurrent attacks of aphonia (inability to speak) and of coughing, attacks that came on and passed off spontaneously. Freud soon discovers that Dora's illness is connected to the love affair her father (...) is having with a Frau K., a family acquaintance, while the lover's husband is courting Dora herself. In analyzing the history of Dora, Freud unfolds the course of events that brought Dora to the clinic and produces her case by means of a fragmentary discourse consisting of Dora's speech, her dreams and thoughts as revealed to Freud while the analysis was going on. The psychoanalytic discourse yet also consists of Freud's own reports and interpretations of Dora's dreams, actions and speech and of his overall understanding of her case, an understanding that undergoes a few radical changes during the analysis. When Dora decides to leave the treatment three months later, which is much too soon in Freud's view, Freud interprets her act as an act of vengeance against himself, repeating her neurotic reactions to the romantic complexity she recounted through the person of Freud. However, when Freud learns later that Dora got married and has overcome her hysterical sicknesses, he re-reads her second dream as announcing that Dora was about to tear herself free from her father (from Mr. K. she tore herself free through an act of vengeance) and "had been reclaimed once more by the realities of life."1How has the narration of the case of Dora by herself and by Freud, changed her situation from a hysterical subject who suffers from severe symptoms, to a subject "able to be reclaimed by the realities of life"? [End Page 118] How has Dora's spoken words to Freud, and his way of responding and directing her speech, changed her situation so radically? What is the power of narrative in changing or affecting the object of narration? What constitutes the "true story" of a subject and how is it affected by the narrative modes by which the story is presented? Can narrative change the facts of the matter narrated? In this paper, as part of the attempt to define the constitutive power of narrative, a power that cannot yet reduce the constituted subject to an effect of discourse (Dora after psychoanalysis surely cannot be viewed as a construct of discourse, yet is so different from what she was prior to analysis), we will examine these questions as addressed in two, apparently diverse, contexts: that of analytic aesthetics and that of psychoanalytic thought. We will show that these two perspectives tackle similar problems regarding narrativity yet choose to solve them in ways that raise important questions regarding the effects of narrative.IIt is a widely spread opinion about narrative that it creates its own world in the act of telling, that "the structures of narrative impose some kind of barrier between language and fact; rather than being directly 'mirrored', the facts, as represented in narrative, are filtered through layers of linguistic artifice."2 The diagnosis that narrative somehow distorts or constructs the events it recounts, that narration changes the modality of what is narrated, is one important implication of the booming interest in narrative in the 1980s and 90s. To understand how such an implication was drawn, requires that the nature of the interest in narrative is more closely qualified as part of the growing attention paid to the pervasiveness of narrative in discourses traditionally considered to lie outside the domain of narrative rendering, and to the naturalness of narrative presentation in extra-literary contexts. These pervasiveness and naturalness of narrative were often interpreted as reflecting the literariness or fictionality of discourses that officially claim to be committed to reality and truth.Yet, how did it come about that the discovery of narrative elements in a wide variety of contexts was interpreted as entailing the fictionalizing of these discursive contexts? As narrative entails the imposition of structure on... (shrink)

Evolutionary systems biology (ESB) aims to integrate methods from systems biology and evolutionary biology to go beyond the current limitations in both fields. This article clarifies some conceptual difficulties of this integration project, and shows how they can be overcome. The main challenge we consider involves the integration of evolutionary biology with developmental dynamics, illustrated with two examples. First, we examine historical tensions between efforts to define general evolutionary principles and articulation of detailed mechanistic explanations of specific traits. Next, these (...) tensions are further clarified by considering a recent case from another field focused on developmental dynamics: stem cell biology. In the stem cell case, incompatible explanatory aims block integration. Experimental approaches aim at mechanistic explanation while dynamical system models offer explanation in terms of general principles. We then discuss an ESB case in which integration succeeds: search for general attractors using a dynamical systems framework synergizes with the experimental search for detailed mechanisms. Contrasts between the positive and negative cases suggest general lessons for achieving an integrated understanding of developmental and evolutionary dynamics. The key integrative move is to acknowledge two complementary aims, both relevant to explanation: identifying the space of possible dynamic states and trajectories, and mechanistic understanding of causal interactions underlying a specific phenomenon of interest. These two aims can support one another in a joint project characterizing dynamic aspects of evolving lineages. This more inclusive project can lead to insights that cannot be reached by either approach in isolation. (shrink)

The positive operator (valued) measures (POMs) allow one to generalize the notion of observable beyond the traditional one based on projection valued measures (PVMs). Here, we argue that this generalized conception of observable enables a consistent notion of unsharp reality and with it an adequate concept of joint properties. A sharp or unsharp property manifests itself as an element of sharp or unsharp reality by its tendency to become actual or to actualize a specific measurement outcome. This actualization tendency—or potentiality—of (...) a property is quantified by the associated quantum probability. The resulting single-case interpretation of probability as a degree of reality will be explained in detail and its role in addressing the tensions between quantum and classical accounts of the physical world will be elucidated. It will be shown that potentiality can be viewed as a causal agency that evolves in a well-defined way. (shrink)

A just social arrangement must guarantee a right to health care for all. This right should be understood as a positive right to basic human functional capabilities. The present article aims to delineate the right to health care as part of an account of distributive justice in health care in terms of the sufficiency of basic human functional capabilities. According to the proposed account, every individual currently living beneath the sufficiency threshold or in jeopardy of falling beneath the threshold has (...) a legitimate claim to justice. People's entitlements to health care should not be determined on the basis of brute luck and their efforts to maintain healthy lifestyles. The prioritization of competing claim-rights of individuals is guided by two allocation principles: number and benefit-size weighted sufficiency (among people beneath the threshold) and need-weighted utilitarianism (among people above the threshold).

Recent years have seen a surge in accounts motivated by information theory that consider language production to be partially driven by a preference for communicative efficiency. Evidence from discourse production (i.e., production beyond the sentence level) has been argued to suggest that speakers distribute information across discourse so as to hold the conditional per-word entropy associated with each word constant, which would facilitate efficient information transfer (Genzel & Charniak, 2002). This hypothesis implies that the conditional (contextualized) probabilities of linguistic units (...) affect speakers’ preferences during production. Here, we extend this work in two ways. First, we explore how preceding cues are integrated into contextualized probabilities, a question which so far has received little to no attention. Specifically, we investigate how a cue's maximal informativity about upcoming words (the cue's effectiveness) decays as a function of the cue's recency. Based on properties of linguistic discourses as well as properties of human memory, we analytically derive a model of cue effectiveness decay and evaluate it against cross-linguistic data from 12 languages. Second, we relate the information theoretic accounts of discourse production to well-established mechanistic (activation-based) accounts: We relate contextualized probability distributions over words to their relative activation in a lexical network given preceding discourse.

This paper describes an experimental course in the preparation of art teachers. The goal of the course was to engage final-year art students in thinking about the fundamental questions in aesthetic education and in considering various views of their roles as teachers of art. The classes presented a dialogue between two teachers: a philosopher of art and an artist. We discussed the social justification of art, the place of art in education and more generally the portrayal of visual culture in (...) philosophical thought. The bibliography for the course comprised a list of basic texts in aesthetic education, from Friedrich Schiller to Nelson Goodman. In class we linked the range of philosophical views examined to the artistic exploration of themes (mainly in contemporary and local art). The course also incorporated guest speakers who presented their own projects relating to different meeting points of art and education, including social-activist artists, curators, philosophers of education and school architects. The article presents the rationale for the course, its method and a sample of its content. (shrink)

Ninety-one nurse champions from three tertiary medical centers in Israel participated.FindingsGiven high network density, high levels of advice play a bigger role in achieving high radicalness compared with lower levels advice. High network density is also related to higher radicalness when networks (...) have high role diversity.DiscussionUsing an SLB framework, the findings suggest that nurse champions best promote adoption of innovation and offer radical changes in their organizations through professional advice given by colleagues in their field network. Healthcare organizations should establish the structure and promote the development of dense and heterogeneous professional networks to realize organizations’ goals and nurses’ responsibility to their professional employees, patients, and society.

There is now considerable evidence that human sentence processing is expectation based: As people read a sentence, they use their statistical experience with their language to generate predictions about upcoming syntactic structure. This study examines how sentence processing is affected by readers' uncertainty about those expectations. In a self-paced reading study, we use lexical subcategorization distributions to factorially manipulate both the strength of expectations and the uncertainty about them. We compare two types of uncertainty: uncertainty about the verb's complement, reflecting (...) the next prediction step; and uncertainty about the full sentence, reflecting an unbounded number of prediction steps. We find that uncertainty about the full structure, but not about the next step, was a significant predictor of processing difficulty: Greater reduction in uncertainty was correlated with increased reading times. We additionally replicated previously observed effects of expectation violation, orthogonal to the effect of uncertainty. This suggests that both surprisal and uncertainty affect human RTs. We discuss the consequences for theories of sentence comprehension. (shrink)
