Posterior parietal cortex has traditionally been considered to be a sensory association area in which higher-order processing and intermodal integration of incoming sensory information occurs. In this paper, evidence from clinical reports and from lesion and behavioral-electrophysiological experiments using monkeys is reviewed and discussed in relation to the overall functional organization of posterior parietal association cortex, and particularly with respect to a proposed posterior parietal mechanism concerned with the initiation and control of certain classes of eye and limb movements. (...) Preliminary data from studies of the effects of posterior parietal lesions on oculomotor control in monkeys are reported.The behavioral effects of lesions of posterior parietal cortex in monkeys have been found to be similar to those which follow analogous damage of the minor hemisphere in humans, while behavioral-electrophysiological experiments have disclosed classes of neurons in this area which have functional properties closely related to the behavioral acts that are disrupted by lesions of the area. On the basis of current data from these areas of study, it is proposed that the sensory association model of posterior parietal function is inadequate to account for the complexities of the present evidence. Instead, it now appears that many diverse neural mechanisms are locatedin partin parietal cortex, that some of these mechanisms are involved in sensory processing and perceptual functions, but that others participate in motor control, and that still others are involved in attentional, motivational, or emotional processes. It is further proposed that the elementary units of these various neural mechanisms are distributed within posterior parietal cortex according to the columnar hypothesis of Mountcastle. (shrink)

Perception is a first-person internal sensation induced within the nervous system at the time of arrival of sensory stimuli from objects in the environment. Lack of access to the first-person properties has limited viewing perception as an emergent property and it is currently being studied using third-person observed findings from various levels. One feasible approach to understand its mechanism is to build a hypothesis for the specific conditions and required circuit features of the nodal points where the mechanistic operation of (...) perception take place for one type of sensation in one species and to verify it for the presence of comparable circuit properties for perceiving a different sensation in a different species. The present work explains visual perception in mammalian nervous system from a first-person frame of reference and provides explanations for the homogeneity of perception of visual stimuli above flicker fusion frequency, the perception of objects at locations different from their actual position, the smooth pursuit and saccadic eye movements, the perception of object borders, and perception of pressure phosphenes. Using results from temporal resolution studies and the known details of visual cortical circuitry, explanations are provided for (a) the perception of rapidly changing visual stimuli, (b) how the perception of objects occurs in the correct orientation even though, according to the third-person view, activity from the visual stimulus reaches the cortices in an inverted manner and (c) the functional significance of well-conserved columnar organization of the visual cortex. A comparable circuitry detected in a different nervous system in a remote species-the olfactory circuitry of the fruit fly Drosophila melanogaster-provides an opportunity to explore circuit functions using genetic manipulations, which, along with high-resolution microscopic techniques and lipid membrane interaction studies, will be able to verify the structure-function details of the presented mechanism of perception.

We review the evidence for the concept of the “initial” or prototype brain. We outline four possible modes of brain evolution suggested by our new findings on the evolutionary status of the dolphin brain. The four modes involve various forms of deviation from and conformity to the hypothesized initial brain type. These include examples of conservative evolution, progressive evolution, and combinations of the two in which features of one or the other become dominant. The four types of neocortical organization (...) in extant mammals may be the result of selective pressures on sensory/motor systems resulting in divergent patterns of brain phylogenesis. A modular “modification/multiplication” hypothesis is proposed as a mechanism of neocortical evolution in eutherians. Representative models of the initial ancestral group of mammals include not only extant basal Insectivora but also Chiroptera; we have found that dolphins and large whales have also retained many features of the archetypal or initial brain. This group evolved from the initial mammalian stock and returned to the aquatic environment some 50 million years ago. This unique experiment of nature shows the effects of radical changes in environment on brain-body adaptations and specializations. Although the dolphin brain has certain quantitative characteristics of the evolutionary changes seen in the higher terrestrial mammals, it has also retained many of the conservative structural features of the initial brain. Its neocortical organization is accordingly different, largely in a quantitative sense, from that of terrestrial models of the initial brain such as the hedgehog. (shrink)

I have argued in other work that emotion, attentional functions, and executive functions are three interpenetrant global state variables, essentially differential slices of the consciousness pie. This paper will outline the columnar architecture and connectivities of the PAG (periaqueductal gray), its role in organizing prototype states of emotion, and the re-entry of PAG with the extended reticular thalamic activating system (“ERTAS”). At the end we will outline some potential implications of these connectivities for possible functional correlates of PAG networks (...) that are just starting to be mapped. Overall, we will look at many lines of evidence that PAG should be conceptualized as a peri-reticular structure that has a foundational role in emotion, in generating the meaningful organization of behavior by the brain through prototype emotional states, and in allowing the various emotional systems to globally influence and tune both the forebrain and brainstem. Finally, we address implications of these concepts for what is currently understood about consciousness, underlining the need for somewhat more humility within consciousness studies about our current level of understanding of consciousness in the brain, combined with a deeper appreciation of the intrinsic connections between emotion and consciousness. One hopes that more concerted empirical interest in structures underneath the thalamus, combined with a deeper appreciation for the fundamental role that organismic and social value must have in bootstrapping awareness in the developing brain, would begin more widely to influence the fundamental lines of neuroscientific research in both emotion studies and consciousness studies.

The original intent of business education in America focused on the development of professional managers who would look after the interests of society. As economic and shareholder theories influenced business education, firm performance became the manager’s top – if not only – priority. The economic responsibility of the firm also appears to be dominating scholarly interest in organisations as well. However, business firms constitute part of the fabric of society and closer attention should be paid by organisation researchers to the (...) social responsibilities of the firm. In doing so, a more balanced research approach can be achieved. In this article, we give evidence that research within the study of the organisation, specifically in the field of management, has predominately turned its attention to the economic responsibility of the firm. We close by demonstrating that other fields within organisation research also appear to be favouring the study of performance and we offer suggestions as to how scholars might better address the firm’s role in society beyond its economic responsibility.

An ethical evaluation of employee participation to decision-making has to be based, obviously, on a theory about ethics, but also on an understanding of the role and the impact of participation in the organisation. This paper aims at sketching different organisational paradigms, and analysing their normative prescriptions w.r.t. participation. It will appear that the recognition of the social nature of man and the acknowledgement of the existence of differentiated goals could enhance the positive outcomes of participation. Next, we will examine (...) to what extent a systemic approach and a stakeholder concept of the firm can meet these requirements. The necessity of a global approach to participation will be emphasised. Consequently, we suggest in the last section of this paper that participation should be extended to the definition of a shared value horizon. (shrink)

To understand the mind, we need to draw equally on the fields of cognitive science and neuroscience. But these two fields have very separate intellectual roots, and very different styles. So how can these two be reconciled in order to develop a full understanding of the mind and brain.This is the focus of this landmark new book.

There is presently considerable interest in the phenomenon of "self-organisation" in dynamical systems. The rough idea of self-organisation is that a structure appears "by itself in a dynamical system, with reasonably high probability, in a reasonably short time, with no help from a special initial state, or interaction with an external system. What is often missed, however, is that the standard evolutionary account of the origin of multi-cellular life fits this definition, so that higher living organisms are also products of (...) self-organisation. Very few kinds of object can selforganise, and the question of what such objects are like is a suitable mathematical problem. Extending the familiar notion of algorithmic complexity into the context of dynamical systems, we obtain a notion of "dynamical complexity". A simple theorem then shows that only objects of very low dynamical complexity can self organise, so that living organisms must be of low dynamical complexity. On the other hand, symmetry considerations suggest that living organisms are highly complex, relative to the dynamical laws, due to their large size and high degree of irregularity. In particular, it is shown that since dynamical laws operate locally, and do not vary across space and time, they cannot produce any specific large and irregular structure with high probability in a short time. These arguments suggest that standard evolutionary theories of the origin of higher organisms are incomplete. (shrink)

This paper argues that biological organisation can be legitimately conceived of as an intrinsically teleological causal regime. The core of the argument consists in establishing a connection between organisation and teleology through the concept of self-determination: biological organisation determines itself in the sense that the effects of its activity contribute to determine its own conditions of existence. We suggest that not any kind of circular regime realises self-determination, which should be specifically understood as self-constraint: in biological systems, in particular, self-constraint (...) takes the form of closure, i.e. a network of mutually dependent constitutive constraints. We then explore the occurrence of intrinsic teleology in the biological domain and beyond. On the one hand, the organisational account might possibly concede that supra-organismal biological systems could realise closure, and hence be teleological. On the other hand, the realisation of closure beyond the biological realm appears to be highly unlikely. In turn, the occurrence of simpler forms of self-determination remains a controversial issue, in particular with respect to the case of self-organising dissipative systems. (shrink)

The article provides a context for the discussion of development coalitions as a key feature of modern political and economic life. It traces the history of research programmes in work organisation over the past four decades, especially in North Western Europe, and challenges conventional views on the status of research in the social sciences.

Le monde muséal a considérablement évolué ces dernières années ; des notions telles que le développement touristique et économique, ou la performance, ont largement pris le pas sur les préoccupations sociales, voire sur la conservation du patrimoine. Dans une logique mondialisée, quelques grands « musées superstars », à l’instar du musée Guggenheim de Bilbao, imposent largement leur logique de fonctionnement, au détriment de nombre d’établissements de taille plus modeste. Le rôle particulier de l’État, en France, contribue au développement d’une infrastructure (...) muséale exceptionnelle, partiellement pour maintenir sa position dominante au niveau des flux de migration touristique. Mais ce renouveau patrimonial induit également un changement de culture sur le plan organisationnel. Des personnels purement administratifs remplacent les personnels scientifiques à la tête des établissements. L’autorité publique et l’intérêt économique encourent le risque de prendre le dessus sur l’intérêt scientifique et patrimonial.The world of museums has changed considerably in recent years, with concerns for tourist and economic development, or performance, largely overshadowing social and even heritage conservation concerns. Following the logic of globalisation, a few “superstar museums”, like the Guggenheim in Bilbao, have been imposing their own modus operandi to the overall detriment of more modest establishments. The particular role of the State, in France, has contributed to the development of an outstanding museum infrastructure, in part to sustain a dominant position in terms of incoming tourist flows. However, this new perspective on heritage has also brought a change in the culture of museum organisation. As scientific staff are replaced by purely administrative staff at management level, the interests of the public authorities and the economy are increasingly liable to outweigh the interests of science and heritage.

This paper presents a conceptual framework for the study of social intelligence in a real-life environment. It is focussed on the dialogue organisation in argumentation, in particular how our understanding of dialogue phenomena in mediated communication may help us to support natural interaction in classroom debates. Dialogue organisation is explored in terms of the cohesive structure of dialogue that emerges as the result of information maintenance and change, specified locally by the adjacency pair and turn-taking, and globally by topic threads. (...) We give a descriptive analysis of their interplay in real chat debates, based on lexical chains of repeated words in an attempt to clarify what feedback participants in the debate require in order to reflect on their contributions to the debate. We then show how this analysis can be used as a basis for conceptual design of a feedback adviser tool to automatically search for topics in student chat debates. Much of the data used in our analysis has been generated as part of the SCALE project SCALE (Internet-based intelligent tool to support collaborative argumentation-based learning in secondary schools) – EU Framework V project. focussed on specifying tools for computer supported argumentation in the classroom.

In this essay I propose a new reading of Michel Foucault’s main thesis about biopower and biopolitics. I argue that organisation represents the neglected key to Foucault’s new conceptualisation of power as something that is less political and more organisational. This unique contribution was lost even on his closest interlocutors. Foucault’s work on power had a strong influence on organisation and management theory but interestingly not for the reasons I am proposing. In fact, although theorists in management and organisation studies (...) have emphasised power in relation to discipline, control and subjectivity they have overlooked the transformative meaning of Foucault’s organisation. His work on biopolitics has attracted opposition, too, as evidenced by the controversy sparked by Giorgio Agamben about Foucault’s biopolitics. From Agamben’s critique, it appears that Foucault’s notions of politics and power do not allow a deconstruction of the violence of the concentration camp. However, a critical reading of Primo Levi’s biographical narratives reveals the camp as a place where the prisoners’ability to organise their daily lives secured survival. To make sense of Levi’s revelation, I use John Dewey’s notion of habits as forms of organisation and reconnect it to Foucault’s organisation. A shared understanding of the objective conditions of human activity and experience highlights the similarities between Dewey’s pragmatism and Foucault’s pragmatic metaphysics. In the end, however, Foucault’s metaphysical background has caught up with him, pushing him away from his own most radical proposal that organisation was the new form of power and the new substance of politics.

Neuromodelling is one of the techniques of modern neurosciences. The “at a distance” type of triadic synapse is probably the prevailing form of impulse transmission in many parts of the brain. If the genetically controlled cell-to-cell neuronal interconnections are abandoned, self-organisation may be the mechanism of structure formation in the brain. This assumption weakens the position of the reflex arc as the basic functional unit of nervous activities.

This collection of essays explores the questions of what counted as knowledge in Victorian Britain, who defined knowledge and the knowledgeable, by what means and by what criteria. During the Victorian period, the structure of knowledge took on a new and recognizably modern form, and the disciplines that we now take for granted took shape. The ways in which knowledge was tested also took on a new form, with oral examinations and personal contacts giving way to formal written tests. New (...) institutions of knowledge were created: museums were important at the start of the period ; by the end, universities had taken on a new prominence. Knowledge exploded and Victorians needed to make sense of the sheer scale of information, to popularize it, and at the same time to exclude ignorance and error - a role carried out by encyclopaedias and popular publications. The concept of knowledge is complex and much debated, with a multiplicity of meanings and troubling relationships. By studying the Victorian organization of knowledge in its institutional, social, and intellectual settings, these essays contribute to our consideration of these wider issues. (shrink)

This book examines the organization as embodied experience. An international range of contributors is assembled to deal explicitly with the 'maternal' aspects of organization. This challenging book will be of essential interest to all critical management theorists. With its innovative approach, it will also appeal to students, teachers, and all those looking for an approach to management that does justice to the complexity, ambivalence and chaos of the world of organizing.

Corporate social responsibility (CSR) has become an increasingly significant managerial concept, yet the manager as an agent of corporate bureaucracy has been substantially missing from both the analytical and conceptual literature dealing with CSR. This article, which is both interpretative in nature and specific in reference to the U.K. cultural context, represents an attempt at addressing this lacuna by utilising qualitative data to explore the perceptions of managers working in corporations with developed CSR programmes. Exploring managerial perceptions of motives for (...) CSR initiatives, methods of stakeholder engagement, organisational integration of CSR and its impact on managerial work, this study concludes that an instrumental approach dominates, which indicates an external-internal organisational paradox in the design and execution of CSR initiatives.

Intermediate filaments, which form the structural framework of both the cytoskeleton and the nuclear lamina in most eukaryotic cells, have been found to be highly dynamic structures. A continuous exchange of subunit proteins at the filament surface and a stabilisation of soluble subunits by chaperone‐type proteins may modulate filament structure and plasticity. Recent studies on the cell cycle‐dependent interaction of intermediate filaments with associated proteins, and a detailed analysis of intermediate filament phosphorylation in defined subcellular locations at various stages of (...) mitosis, have brought new insights into the molecular mechanisms involved in the mitotic reorganisation of intermediate filaments. Some of these studies have allowed new speculations about the possible cellular functions of cytoplasmic intermediate filaments, and increased our understanding of the specific functions of the lamins and the lamina‐associated membrane proteins in the post‐mitotic reassembly of the nucleus.
