BACKGROUND: Hallucinations and delusions that complicate Parkinson’s disease could lead to nursing home placement and are linked to increased mortality. Cognitive impairments are typically associated with the presence of hallucinations but there are no data regarding whether such a relationship exists with delusions. OBJECTIVE: We hypothesized that hallucinations would be associated with executive and visuospatial disturbance. An exploratory examination of cognitive correlates of delusions was also completed to address the question of whether they differ from hallucinations. METHODS: 144 PD subjects (...) completed a neuropsychological battery to assess cognition and the SAPS to examine psychosis. Correlational analyses assessed associations between hallucinations and delusions with cognitive domains. RESULTS: 48 subjects reported psychotic symptoms: 25 experienced hallucinations without delusions, 23 had symptoms dominated by delusions. Severity and/or number of hallucination subtypes were significantly correlated with lower scores in language, memory, attention, executive functioning, and visuospatial ability. Correlations with delusions were non-significant. Tests of differences in the size of the correlations between groups revealed a significant relationship between language and visuospatial performance with hallucinations. CONCLUSIONS: Cognitive correlates of hallucinations and delusions appear to be different in PD, suggesting distinct pathogenic mechanisms and possibly anatomical substrates. Hence, delusions may not share the same associations with dementia as hallucinations. Since this is a new finding, further studies will be needed to confirm our results. (shrink)

How do newborns learn to recognize objects? According to temporal learning models in computational neuroscience, the brain constructs object representations by extracting smoothly changing features from the environment. To date, however, it is unknown whether newborns depend on smoothly changing features to build invariant object representations. Here, we used an automated controlled-rearing method to examine whether visual experience with smoothly changing features facilitates the development of view-invariant object recognition in a newborn animal model—the domestic chick. When newborn chicks were reared (...) with a virtual object that moved smoothly over time, the chicks created view-invariant representations that were selective for object identity and tolerant to viewpoint changes. Conversely, when newborn chicks were reared with a temporally non-smooth object, the chicks developed less selectivity for identity features and less tolerance to viewpoint changes. These results provide evidence for a “smoothness constraint” on the development of invariant object recognition and indicate that newborns leverage the temporal smoothness of natural visual environments to build abstract mental models of objects.

We use data collected among Hadza hunter-gatherers between 2005 and 2009 to examine hypotheses about the causes and consequences of men’s foraging and food sharing. We find that Hadza men foraged for a range of food types, including fruit, honey, small animals, and large game. Large game were shared not like common goods, but in ways that significantly advantaged producers’ households. Food sharing and consumption data show that men channeled the foods they produced to their wives, children, and their consanguineal (...) and affinal kin living in other households. On average, single men brought food to camp on 28% of days, married men without children at home on 31% of days, and married men with children at home on 42% of days. Married men brought fruit, the least widely shared resource, to camp significantly more often than single men. A model of the relationship between hunting success and household food consumption indicates that the best hunters provided 3–4 times the amount of food to their families than median or poor hunters. These new data fill important gaps in our knowledge of the subsistence economy of the Hadza and uphold predictions derived from the household and kin provisioning hypotheses. Key evidence and assumptions backing prior claims that Hadza hunting is largely a form of status competition were not replicated in our study. In light of this, family provisioning is a more viable explanation for why good hunters are preferred as husbands and have higher fertility than others. (shrink)

When we have asked Hadza whether married couples should live with the family of the wife (uxorilocally) or the family of the husband (virilocally), we are often told that young couples should spend the first years of a marriage living with the wife’s family, and then later, after a few children have been born, the couple has more freedom—they can continue to reside with the wife’s kin, or else they could join the husband’s kin, or perhaps live in a camp (...) where there are no close kin. In this paper, we address why shifts in kin coresidence patterns may arise in the later years of a marriage, after the birth of children. To do so, we model the inclusive fitness costs that wives might experience from leaving their own kin and joining their husband’s kin as a function of the number of children in their nuclear family. Our model suggests that such shifts should become less costly to wives as their families grow. This simple model may help explain some of the dynamics of postmarital residence among the Hadza and offer insight into the dynamics of multilocal residence, the most prevalent form of postmarital residence among foragers.

What role does experience play in the development of face recognition? A growing body of evidence indicates that newborn brains need slowly changing visual experiences to develop accurate visual recognition abilities. All of the work supporting this “slowness constraint” on visual development comes from studies testing basic‐level object recognition. Here, we present the results of controlled‐rearing experiments that provide evidence for a slowness constraint on the development of face recognition, a prototypical subordinate‐level object recognition task. We found that (1) newborn (...) chicks can rapidly develop view‐invariant face recognition and (2) the development of this ability relies on experience with slowly moving faces. When chicks were reared with quickly moving faces, they built distorted face representations that largely lacked invariance to viewpoint changes, effectively “breaking” their face recognition abilities. These results provide causal evidence that slowly changing visual experiences play a critical role in the development of face recognition, akin to basic‐level object recognition. Thus, face recognition is not a hardwired property of vision but is learned rapidly as the visual system adapts to the temporal structure of the animal's visual environment. (shrink)

When we read Karl M&IX,S descriptions of the capitalist mode of production in Capital amd other writings, all our instincts tell us that these are descriptions of an unjust social system. Marx describes a. society in which one small class of persons lives in comfort and idleness while another class, in ever-increasing numbers, lives in want and vvrctchedncss, laboring to produce thc Wealth enjoyed by the fixst. Marx speaks constantly of capitalist "exploitation" of the worker, and refers to the creation (...) of surplus value as the appropriation of his "unpaid 1abor" by capital. Not 0nly docs capitalist society, as Marx describes it, strike us as unjust, but his own descriptions of it themselves seem to connote injustice. When we look in the writings of Marx and Engels for a detailed account 0f the injustices of capitalism, however, We discover at once that not only is there no attempt at all in their writings to provide an argument that capitalism is unjust, but there is not even the explicit claim that capitalism is unjust 01* incquitablc, 01* that it violatcs anyonds rights. We find, in fact, explicit denunciations and sustained criticisms of social thinkers (such as Pierre P:roudhon and Ferdinand Lassalle) who did condemn capitalism for its injustices or advocated some form of socialism as a. means of securing justice, equality, or the rights of man. We even find, perhaps to our surprise, some faixly explicit statements to the effect that capitalism, with all its manifold defects, cannot be faultcd as far as justice is concerned. Whatever else capitalism may be for Marx, it docs not seem that it is unjust. (shrink)

The purpose of this research is to present the major factors that lead to ethical dissolution in an organization. Specifically, drawing from a wide spectrum of sources, this study explores the impact of organizational, individual, and contextual factors that converge to contribute to ethical dissolution. Acknowledging that ethical decisions are, in the final analysis, made by individuals, this study presents a model of ethical dissolution that gives insight into how a variety of elements coalesce to draw individuals into decisions that (...) result in the ethical undoing of an otherwise healthy organization. ENRON, TYCO and WorldCom did not happen in a vacuum. Nor can such debacles be explained as simply one or two individuals who were morally corrupt. The ethical breakdowns that occurred in these companies happened over a period of time, involved numerous individuals both inside and outside of the organization, and brought about the implosion of viable companies. Seeking to extend the work of previous researchers, this study attempts to tie together a disparate set of factors into a cohesive explanation of ethical breakdowns in organizations. (shrink)

Filled with insightful reflections on teaching oral history, it offers practical suggestions for educators seeking to create curricula, engage students, gather community support, and meet educational standards. By the close of the book, readers will be able to successfully incorporate oral history projects in their own classrooms.

This volume explores how Catholicism began and continues to open its doors to the wider world and to other confessions in embracing ecumenism, thanks to the vision and legacy of the Second Vatican Council. It explores such themes as the twentieth century context preceding the council; parallels between Vatican II and previous councils; its distinctively pastoral character; the legacy of the council in relation to issues such as church-world dynamics, as well as to ethics, social justice, economic activity. Several chapters (...) discuss the role of women in the church before, during, and since the council. Others discern inculturation in relation to Vatican II. The book also contains a wide and original range of ecumenical considerations of the council, including by and in relation to Free Church, Reformed, Orthodox, and Anglican perspectives. Finally, it considers the Council’s ongoing promise and remaining challenges with regard to ecumenical issues, including a groundbreaking essay on the future of ecumenical dialogue by Cardinal Walter Kasper.

While rooted in careful study of Mead’s original writings and transcribed lectures and the historical context in which that work was carried out, the papers in this volume have brought Mead’s work to bear on contemporary issues in metaphysics, epistemology, cognitive science, and social and political philosophy.

This book's importance is derived from three sources: careful conceptualization of teacher induction from historical, methodological, and international perspectives; systematic reviews of research literature relevant to various aspects of teacher induction including its social, cultural, and political contexts, program components and forms, and the range of its effects; substantial empirical studies on the important issues of teacher induction with different kinds of methodologies that exemplify future directions and approaches to the research in teacher induction.

Allen Wood “What is the human being?” Kant sometimes treated this question as the most fundamental question of all philosophy: “The field of philosophy in the cosmopolitan sense can be brought down to the following questions: 1. What can I know? 1. What ought I to do? 1. What may I hope? 1. What is the human being? Metaphysics answers the first question, morals the second, religion the third, and anthropology the fourth. Fundamentally, however, we could reckon all of (...) this to anthropology, because the first three questions refer to the last one”.[i]. (shrink)

It is well known that Hegel contrasts the “Moral standpoint” or “morality” with the higher standpoint of “social ethics” or “ethical life”, and that he regards Kant’s ethical theory as an expression of the moral standpoint. Hegel finds many shortcomings in the moral standpoint, but probably the most famous of Hegel’s criticisms of Kantian moral theory is the charge that Kant’s theory is an “empty formalism,” incapable of providing any “immanent doctrine of duties,” The Kantian moral law, says Hegel, has (...) no content; its only criterion of morally right action is non-contradictoriness, and that proves to be no criterion at all, because it is a criterion which even the most immoral actions are able to satisfy.

The "impression of will" is intended to pick out the experience of willing an act. Hume discusses this impression in the Treatise primarily in terms of its psychological setting, describing it as "the internal impression we feel and are conscious of, when we knowingly give rise to any new motion of our body, or new perception of our mind".1 It is not obvious what Hume means in this and related passages. Scholars have offered a number of suggestions about how the (...) impression of will fits into Hume's overall moral psychology.2 But the specific issue I want to raise here concerns two substantive claims about the experience of willing an act that are attributed to Hume with some frequency.

Paul Guyer's paper "Naturalistic and Transcendental Moments in Kant's Moral Philosophy" raises a set of issues about how Kantian ethics should be understood in relation to present day "philosophical naturalism" that are very much in need of discussion. The paper itself is challenging, even in some respects iconoclastic, and provides a highly welcome provocation to raise in new ways some basic questions about what Kantian ethics is and what it ought to be. Guyer offers us an admirably informed and complex (...) argument, both historical and philosophical, that tangles with some of the most difficult problems in Kant's moral philosophy. It begins with some ambitious and controversial claims about Kant's moral philosophy prior to the Groundwork of 1785. It then offers an interpretation, and also a fundamental criticism, of the Groundwork's attempt to establish the moral law based on the idea of freedom of the will. And finally, it raises - and expresses some opinions on - the large and vexed questions of the relationship between transcendental philosophy and philosophical naturalism, and whether Kantian ethics can be made consistent with a naturalistic philosophical outlook. In these comments I will have something to say on each of these three topics, without pretending (any more than Guyer does) to have exhausted what might be said about them. (shrink)

This article focuses on the question of whether Social Issues in Management (SIM) is a “field” and, if so, what kind, emphasizing specifically the recent literature on corporate social responsibility and performance (CSR/csp). Fields are defined in part by coherent bodies of knowledge that serve as guideposts for current research, and so the authors construct a simple model of CSR/csp scholarship, illustrating the relevant categories with representative publications. The authors conclude that SIM is a “low-paradigm” field but is not recognized (...) or accepted as a field by many scholars who write about CSR/csp from “outside” the field. This analysis points to the need for SIM scholars to continue to integrate useful ideas from other fields, and also to critique the work of scholars who address “failings” or “gaps” in SIM research without appropriately dealing with the existing SIM literature. The article concludes with some ideas for sustaining the institutional legitimacy of SIM and for challenging those who would “reinvent” a field with a long and fruitful history, including paying careful attention to journal review processes and the content of publications in prominent journals.

In this paper we will show that Hempel's covering law model can't deal very well with explanations that are based on incomplete knowledge. In particular the symmetry thesis, which is an important aspect of the covering law model, turns out to be problematic for these explanations. We will discuss an example of an electric circuit, which clearly indicates that the symmetry of explanation and prediction does not always hold. It will be argued that an alternative logic for causal explanation is (...) needed. And we will investigate to what extent non-monotonic epistemic logic can provide such an alternative logical framework. Finally we will show that our non-monotonic logical analysis of explanation is not only suitable for simple cases such as the electric circuit, but that it also sheds new light on more controversial causal explanations such as Milton Friedman's explanation of the business cycle.

have recently provided a compelling demonstration of enhanced attentional control under post-hypnotic suggestion. Using the classic color-word interference paradigm, in which the task is to ignore a word and to name the color in which it is printed (e.g., RED in green, say ''green''), they gave a post-hypnotic instruction to participants that they would be unable to read. This eliminated Stroop interference in high suggestibility participants but did not alter interference in low suggestibility participants. replicated this pattern and further demonstrated (...) that it is not due to a visual strategy (such as blurring or looking at a different location). As a historical footnote, we describe a ''case study'' from 18 years ago in which we observed the same result using a hypnotic instruction to a single highly suggestible individual that he could not read. The elimination of Stroop interference has important implications for both the study of attention and the study of hypnosis. (shrink)

A model for the trapping of animals with a circular pitfall is formulated. The model's assumptions are: The animals move independently according to the same Brownian motions. The boundary of the pitfall acts as an absorbing or elastic barrier. Initially a fixed number of animals is independently homogeneously distributed over a finite study area, or the initial positions follow a homogeneous planar Poisson process. The model depends on three free parameters: the motility of the animals, their reaction to the pitfall, (...) the initial density.It appears that the catches in disjoint time intervals are multinomially or independently Poisson distributed. The parameters of these distributions are obtained by solving certain partial differential equations. (shrink)

It is the avowed aim of Avineri’s study to "bring out the ambivalent indebtedness of Marx to the Hegelian tradition." This aim determines the central place of Marx’s concept of man in his discussion; for it was from Hegel and the young Hegelians that Marx drew the anthropological problematic which dominates his early writings. The Hegelian concept of Geist served the young Hegelians as the model for a philosophical conception of man, as a being exhibiting the unique dignity of his (...) rational nature in a historical process through which he attains to freedom and self-knowledge. Carrying this aim out with the greatest clarity and completeness was Feuerbach, who, applying to Hegelian philosophy what Avineri calls his "transformative method," attempted to interpret Hegel’s "Spirit" and the speculative concepts through which it knows itself as false inversions of the self-consciousness of man as a natural, sensuous being. It was this method, applied to Hegel’s political philosophy, which resulted in what Avineri describes as "Marx’s first systematic work," the 1843 critique of Hegel’s Philosophy of Right. A full chapter of Avineri’s book is devoted to this "most systematic of [Marx’s] writings on political theory." Avineri views the work as an immanent critique of Hegel’s philosophy of the state, focusing on Hegel’s failure adequately to comprehend the rationality of the actual. The cause of this failure was Hegel’s hypostatization of abstractions as the subjects of the social process; Marx’s application of the "transformative method" was an attempt to understand the specific character of the real human subjects who are the actual foundation of these speculative constructions. Avineri traces in detail the manner in which Marx confronts the speculative functions assigned by Hegel to monarchy, civil estates, and the state bureaucracy with the social realities represented by these speculative categories. Marx argues that the supposed universality of the state is an illusion, mystifying the social practice of modern society and confirmed by Hegel’s philosophical speculation. In fact, he argues, the "universal" interests of the state are only expressions of private interests in what Hegel called the sphere of "civil society," the realm of production and exchange. It is the relationships of men in this sphere which in Marx’s view constitute the true foundation for the rationality of the actual, and it was Hegel’s speculative inversion of the relationship of civil society and the state which was responsible for his failure to grasp this rationality. Marx’s stress on the sphere of civil society as the foundation for political life, the priority of man’s productive life over all other social relationships, is the characteristic Marxian form of the young Hegelian conversion of a speculative science of spirit into a philosophy of man. It was this priority, which Marx later referred to as the "universal result" of his early research, which continued to guide his later studies. Avineri proceeds to take up this theme in a chapter appropriately titled "Homo Faber.". (shrink)
