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)

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)

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.

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.

ABSTRACTRecognising a facial expression is more difficult when the expresser's body conveys incongruent affect. Existing research has documented such interference for universally recognisable bodil...

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)

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)

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.

By the close of the book, readers will be able to successfully incorporate oral history projects in their own classrooms.

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.

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)

This paper studies general numerical networks with support and attack. Our starting point is argumentation networks with the Caminada labelling of three values 1=in, 0=out and ½=undecided. This is generalised to arbitrary values in [01], which enables us to compare with other numerical networks such as predator?prey ecological networks, flow networks, logical modal networks and more. This new point of view allows us to see the place of argumentation networks in the overall landscape of networks and import and export ideas (...) to and from argumentation networks. We make a special effort to make clear how general concepts in general networks relate to the special case of argumentation networks. We pay special attention to the handling of loops and to the special features of numerical support. We find surprising connections with the Dempster?Shafer rule and with the cross-ratio in projective geometry. This paper is an expansion of our 2005 paper and so we also consider higher level features such as numerical attacks on attacks, and propagation of numerical values.We conclude with a brief view of temporal numerical argumentation and with a detailed comparison with related papers published since 2005.

Abstract:In this article we first review the development of the concept of global business citizenship and show how the libertarian political philosophy of free-market capitalism must give way to a communitarian view in order for the voluntaristic, local notion of “corporate citizenship” to take root. We then distinguish the concept of global business citizenship from “corporate citizenship” by showing how the former concept requires a transition from communitarian thinking to a position of universal human rights. In addition, we link global (...) business citizenship to global business strategy and to three analytical levels of ethical norms. Finally, we trace a process whereby global businesses can implement fundamental norms and learn to accommodate to legitimate cultural differences. (shrink)

The traditional Dung networks depict arguments as atomic and study the relationships of attack between them. This can be generalised in two ways. One is to consider various forms of attack, support, feedback, etc. Another is to add content to nodes and put there not just atomic arguments but more structure, e.g. proofs in some logic or simply just formulas from a richer language. This paper offers to use temporal and modal language formulas to represent arguments in the nodes of (...) a network. The suitable semantics for such networks is Kripke semantics. We also introduce a new key concept of usability of an argument. This is the beginning of a continuing research for adding contents to the nodes of an argumentation network. This research will allow us to address notions like ?what does it exactly mean for a node to attack another? or ?what does it mean for a network to be consistent? or ?can we give proper proof rules to manipulate networks?, and more.

This article describes the theory and process of global business citizenship (GBC) and applies it in an analysis of characteristics of company codes of business conduct. GBC is distinguished from a commonly used term, “corporate citizenship,” which often denotes corporate community involvement and philanthropy. The GBC process requires (1) a set of fundamental values embedded in the corporate code of conduct and in corporate policies that reflect universal ethical standards; (2) implementation throughout the organization with thoughtful awareness of where the (...) code and policies fit well and where they might not fit with stakeholder expectations; (3) analysis and experimentation to deal with problem cases; and (4) systematic learning processes to communicate the results of implementation and experiments internally and externally. We then identify and illustrate the three attributes of a code of conduct that would reflect a GBC approach. The three attributes are orientation, implementation, and accountability. The various components of these attributes are specified and illustrated, using website examples from six global petroleum companies. (shrink)

THE PROBLEM OF THE INTERPRETATION OF HAMANN Johann Georg Hamann is an intriguing but poorly known figure in the contemporary intellectual world. Yet this is the man whom Kierkegaard saluted as "Emperor!", whose writings were to have been arranged for publication by none other than Goethe himself, and whom Dilthey numbered among the primordial figures in the rise of modern historical consciousness. There are reasons for the persistence of this general ignorance. Hamann is deep. And, in addition, there is his (...) forbidding style. The readers of Kierkegaard and Dilthey, two other giants who them selves achieved late recognition, have not had to face this kind of imposing obstacle. Not only does Hamann expect his readers to handle themselves in deep water, but to intuit their way between his ideas which bob up like islands with no visible connection between them. Like Kierkegaard too, Hamann has had his troubles with the public. He himself referred to the hope that he would be understood by a "better posterity". In fact only the last few years have seen the printing of some of his more controversial writings, in particular his theories on the nature of human sexuality. (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.

Electroencephalography-neurofeedback has become a valuable tool in the field of psychology, e.g., to improve cognitive function. Nevertheless, a large percentage of NF users seem to be unable to control their own brain activation. Therefore, the aim of this study was to examine whether a different kind of visual feedback could positively influence NF performance after one training session. Virtual reality seems to have beneficial training effects and has already been reported to increase motivational training aspects. In the present study, we (...) tested 61 young healthy adults to investigate, whether 3D VR-based NF training has a more beneficial effect on the sensorimotor rhythm power increase than a mere 2D conventional NF paradigm. In the 3D group, participants had to roll a ball along a predefined path in an immersive virtual environment, whereas the 2D group had to increase the height of a bar. Both paradigms were presented using VR goggles. Participants completed one baseline and six feedback runs with 3 min each, in which they should try to increase SMR power over Cz. Half of the participants received real feedback whereas the other half received sham feedback. Participants receiving 3D VR-based feedback showed a linear increase in SMR power over the feedback runs within one training session. This was the case for the real as well as for the sham 3D feedback group and might be related to more general VR-related effects. The 2D group receiving the conventional bar feedback showed no changes in SMR power over the feedback runs. The present study underlines that the visual feedback modality has differential effects on the NF training performance and that 3D VR-based feedback has advantages over conventional 2D feedback.
