Classical cognitive science has been characterized by an association with the computational theory of mind. Although this association has produced highly significant results, it has also limited the scope of scientific psychology. In this paper, we analyse the limits of the specific kind of computational model represented by the Chomskian-Fodorian tradition in the study of mind and language. In our opinion, the adhesion to the principle of formality imposed by this specific computational model has motivated the exclusion of consciousness in (...) the reflection on language and, consequently, has led to the inability to account for some aspects of language functioning at the processing level of discourse. The aim of this article is to restore the role of consciousness in discourse comprehension and production processes. Specifically, we argue that the ability to produce and understand discourses is based on individuals’ capacity for navigation in space and time. We will show that the space–time orientation is guaranteed by the projection of the self, which involves a special kind of consciousness. (shrink)
Cancer-related electronic support groups (ESGs) may be regarded as a complement to face-to-face groups when the latter are available, and as an alternative when they are not. Advantages over face-to-face groups include an absence of barriers imposed by geographic location, opportunities for anonymity that permit sensitive issues to be discussed, and opportunities to find peers online. ESGs can be especially valuable as navigation aids for those trying to find a way through the healthcare system and as a guide to (...) the cancer journey. Outcome indicators that could be used to evaluate the quality of ESGs as navigation aids need to be developed and tested. Conceptual models for the navigator role, such as the Facilitating Navigator Model, are appropriate for ESGs designed specifically for research purposes. A Shared or Tacit Model may be more appropriate for unmoderated ESGs. Both conceptual models raise issues in Internet research ethics that need to be address. (shrink)
In this article, we describe an ontology aimed at the representation of the relevant entities and relations in the philosophical world. We will guide the reader through our modeling choices, so to highlight the ontology’s practical purpose: to enable an annotation of philosophical resources which is capable of supporting pedagogical navigation mechanisms. The ontology covers all the aspects of philosophy, thus including characterizations of entities such as people, events, documents, and ideas. In particular, here we will present a detailed (...) exposition of the entities belonging to the idea branch of the ontology, for they have a crucial role in the world of philosophy. Moreover, as an example of the type of applications made possible by the ontology we will introduce PhiloSurfical, a prototype tool we created to navigate contextually a classic work in twentieth century philosophy, Wittgenstein’s Tractatus Logico-Philosophicus. We discuss the potential usage of such navigation mechanisms in educational and scholarly contexts, which aim to enhance the learning process through the serendipitous discovery of relevant resources.

This article presents results from simulations studying the hypothesis that mechanisms for landmark-based navigation could have served as preadaptations for compositional language. It is argued that sharing directions would significantly have helped bridge the gap between general and language-specific cognitive faculties. A number of different levels of navigational and communicative abilities are considered, resulting in a range of possible evolutionary paths. The selective pressures for, resp. against, increased complexity in either faculty are then evaluated for a range of environments. (...) The study aims specifically to identify whether there is a viable evolutionary path leading to compositional language, and if so, under what circumstances. The results show that environmental conditions can render a step towards more complex communication either desirable or harmul, and suggest that very specific initial conditions and changes in the environment, resp. the ecological niche occupied, would have been needed to select for compositional language. Subject to these conditions, a (proto)language using order, but no hierarchical structure could evolve. This represents a middle ground, which brings closer hypotheses about syntax that have so far appeared difficult to reconcile. (shrink)
We have considered a simple word game called the word-morph. After making our participants play a stipulated number of word-morph games, we have analyzed the experimental data. We have given a detailed analysis of the learning involved in solving this word game. We propose that people are inclined to learn landmarks when they are asked to navigate from a source to a destination. We note that these landmarks are nodes that have high closeness-centrality ranking.
This article pursues overlapping points about ontology, philosophical method, and our kinship with and difference from nonhuman animals. The ontological point is that being is determinately different in different places not because of differences, or even a space, already given in advance, but in virtue of a negative in being that is regional and rooted in place, which Mer-leau-Ponty calls the “hollow.” The methodological point is that we tend to miss this ontological point because we are inclined to what I (...) call transportable thinking, which conceives of things and spatial determinacy itself as being what they are independent of where they are. I argue that we are inclined this way because, in contrast to other animals, we have a weak sense of where we are. We are lost animals. To compensate for lostness, we abstract ourselves from place and conceptualize ourselves and things by way of a transportable, Cartesian “view from above.”. (shrink)

Dennett argues that the decentralized view of human cognitive organization finding increasing support in parts of cognitive science undermines talk of an inner self. On his view, the causal underpinnings of behavior are distributed across a collection of autonomous subsystems operating without any centralized supervision. Selves are fictions contrived to simplify description and facilitate prediction of behavior with no real correlate inside the mind. Dennett often uses an analogy with termite colonies whose behavior looks organized and purposeful to the external (...) eye, but which is actually the emergent product of uncoordinated activity of separate components marching to the beat of their individual drums. I examine the cognitive organization of a system steering by an internal model of self and environment, and argue that it provides a model that lies between the image of mind as termite colony and a naïve Cartesianism that views the self as inner substance.

A hypertext learner navigates with a instinctive feeling for a knowledge. The learner does not know her queries, although she has a feeling for them. A learnerâs navigation appears as complete upon the emergence of an aesthetic pleasure, called rasa. The order of arrival or the associational logic and even the temporal order are not relevant to this emergence. The completeness of aesthetics is important. The learner does not look for the intention of the writer, neither does she look (...) for significance. Lexia has a suggestive power and she is suggested in the arrival of aesthetics. Hypertext learning does not depend on communication. The learner in her pleasure transgresses the bounds of space-time to be in communion with several writers/learners. Hypertext learning does not appear to be fundamentally different from the analog learning; however, in performance, as in navigation, the learner assumes a mental state that helps her in her emergence into aesthetic bliss, of an arrival to the completed lexial navigation. This completeness is owing to aesthetics and is not owing to either the semantics or the query-fulfilling qualities. (shrink)
There are at least four important, institutional obstacles to whistle-blowing to regulatory institutions. First, regulatory institutions are often systematically understaffed and do not have the resources needed to adequately process whistle-blowing cases. Second, regulators who process whistle-blowing cases are often systematically inexperienced and do not understand the strategic importance of whistle-blowing cases. Third, regulators are often under systemic pressure from the politicians who appoint them to ignore whistle-blowing cases relevant to their sources of financial and/or ideological political support. Fourth, there (...) are high systemic risks to whistle-blowers who blow the whistle to regulatory institutions. Nonetheless, understanding how the institutions and obstacles operate can help us understand what types of whistle-blowing methods can be used to navigate around the obstacles and within the regulatory institutions. In addition, sometimes whistle-blowing methods can help reform regulatory institutions. (shrink)

The mathematical approach to such essentially biological phenomena as perseverative reaching is most welcome. To extend these results and make them more accurate, levels of analysis and neural centers should he distinguished. The navigational nature of sensorimotor control should be characterized more clearly, including the continuous dynamics of neural processes hut not limited to it. In particular, discrete conditions should be formalized mathematically as part of the biological process.
Through the personal stories of managers running global business, this book takes an inside look into the dilemmas of managers who are asked to make profits ethically according to the dictates of their company's ethics code. It examines what companies `think" they are doing to help managers in those situations and how those managers are actually affected. Thanks to the boost from the 1991 Sentencing Guidelines which minimizes penalties for companies with ethics codes caught in ethical wrongdoing, more than 85% (...) of US companies and two thirds of all Canadian companies and half of all European companies now have Codes of Ethics. Yet, over and over, we hear of stories of personal dilemmas and conflicts experienced by individual managers navigating those business waters in other cultures. "Eileen Morgan does an excellent job of mapping the course for navigating the previously uncharted global ethical waters. By identifying best practices, she leads the reader on a journey from Surviving, to Understanding to Knowing the ethical issues that frequently confront international business people. This is a must read for anyone who wants to successfully compete in world markets." -Michael J. Litwin, Executive Vice President, Chief Credit Officer, Heller Financial, Inc. "Eileen Morgan has combined the pragmatic concerns of the individual manager with the moral concerns that come from personal-life history, cultural roots, and corporate ethical culture …This book focuses on the constructive task of formulating and using an "ethical map," and is sure to be a tonic to conscientious managers who want to navigate cross-cultural commerce with integrity. It has done a superb job of creating order out of the complexity of cross-cultural moral experience by insisting that the complexity must be honored and appropriated rather than ignored or suppressed." -Dr. Richard Beauchamp, Professor of Ethics, Christopher Newport University "In this groundbreaking book, Eileen Morgan has provided scores of real-life examples and developed a framework for approaching ethical leadership in international business. This is mandatory reading for anyone involved in global management today...This is an important book on an important subject." -Stephen H. Rhinesmith, Ph.D. Author, A Manager's Guide to Globalization "Eileen Morgan provides us with a much needed roadmap for how to walk the path of ethical leadership with practical feet. She reminds us that ethical decision-making is a critical aspect of every day leadership, and that we can all choose to be 'ethical pioneers' in our companies and our communities. Every leader engaged in global business can benefit from the lessons and stories included in this book." -Christi A. Olson, Ph.D. Chair, Telecommunications Management Department, Golden Gate University "Eileen Morgan's thoughtful analysis of 'ethical capital' should be read by anyone who does business in a global environment…Morgan's book presents the issue clearly, comprehensively and compellingly, demonstrating that ethics is an indispensable aspect of individual leadership and organizational credibility. …It provides a clear roadmap for business leaders who need to communicate their commitment to integrity and accountability to their employees, their partners, and their customer, making their 'ethical capital' one of their most valuable assets." -Nell Minnow, Principal, Lens, The Corporate Governance Investors "Eileen Morgan gives excellent insight into ethical practices. She focuses on business but her insights have general application. This book also describes differences in ethical interpretation that can arise between diverse cultures.

When business organisations become involved in contributing to and resolving social issues, they enter areas traditionally seen as the purview of governments. In doing so, they begin to take on the expectations and responsibilities of government; they become politicised. This politicisation is a product of business’s success and power and appears largely unavoidable. Adopting Matten & Crane’s (2005a) extended view of corporate citizenship, business organisations’ responsibilities extend to the administration of citizens’ social, civil and political rights. We term these areas (...) where business organisations take over the administration of citizenship rights as the social governance gap. Drawing upon the agenda of Margolis and Walsh (2003), we seek to enhance the understanding of how business navigates its responsibilities within the social governance gap, including its function as a significant actor influencing societal development and wellbeing. We do this through an exploration of Rio Tinto’s involvement in the WA Future Fund. This paper forms part of an introductory scoping case study of the Rio Tinto WA Future fund and its function as one of Rio Tinto’s diverse responses to community development issues in Western Australia.

Fodor advocates a view of cognitive processes as computations defined over the language of thought (or Mentalese). Even among those who endorse Mentalese, considerable controversy surrounds its representational format. What semantically relevant structure should scientific psychology attribute to Mentalese symbols? Researchers commonly emphasize logical structure, akin to that displayed by predicate calculus sentences. To counteract this tendency, I discuss computational models of navigation drawn from probabilistic robotics. These models involve computations defined over cognitive maps, which have geometric rather than (...) logical structure. They thereby demonstrate the possibility of rational cognitive processes in an exclusively non-logical representational medium. Furthermore, they offer much promise for the empirical study of animal navigation. (shrink)

The Morris water maze has been put forward in the philosophy of neuroscience as an example of an experimental arrangement that may be used to delineate the cognitive faculty of spatial memory (e.g., Craver and Darden, Theory and method in the neurosciences, University of Pittsburgh Press, Pittsburgh, 2001; Craver, Explaining the brain: Mechanisms and the mosaic unity of neuroscience, Oxford University Press, Oxford, 2007). However, in the experimental and review literature on the water maze throughout the history of its use, (...) we encounter numerous responses to the question of “what” phenomenon it circumscribes ranging from cognitive functions (e.g., “spatial learning”, “spatial navigation”), to representational changes (e.g., “cognitive map formation”) to terms that appear to refer exclusively to observable changes in behavior (e.g., “water maze performance”). To date philosophical analyses of the water maze have not been directed at sorting out what phenomenon the device delineates nor the sources of the different answers to the question of what. I undertake both of these tasks in this paper. I begin with an analysis of Morris’s first published research study using the water maze and demonstrate that he emerged from it with an experimental learning paradigm that at best circumscribed a discrete set of observable changes in behavior. However, it delineated neither a discrete set of representational changes nor a discrete cognitive function. I cite this in combination with a reductionist-oriented research agenda in cellular and molecular neurobiology dating back to the 1980s as two sources of the lack of consistency across the history of the experimental and review literature as to what is under study in the water maze.

Abstract: In this article, the logic and functions of character-trait ascriptions in ethics and epistemology is compared, and two major problems, the "generality problem" for virtue epistemologies and the "global trait problem" for virtue ethics, are shown to be far more similar in structure than is commonly acknowledged. I suggest a way to put the generality problem to work by making full and explicit use of a sliding scale--a "narrow-broad spectrum of trait ascription"-- and by accounting for the various uses (...) of it in an inquiry-pragmatist account. In virtue theories informed by inquiry pragmatism, the agential habits and abilities deemed salient in explanations/evaluations of agents in particular cases, and the determination of what relevant domains and conditions an agent's habit or ability is reliably efficacious in, is determined by pragmatic concerns related to our evaluative epistemic practices.

What is the role of language in social interaction? What does language bring to social encounters? We argue that language can be conceived of as a tool for interacting minds, enabling especially effective and flexible forms of social coordination, perspective-taking and joint action. In a review of evidence from a broad range of disciplines, we pursue elaborations of the language-as-a-tool metaphor, exploring four ways in which language is employed in facilitation of social interaction. We argue that language dramatically extends the (...) possibility-space for interaction, facilitates the profiling and navigation of joint attentional scenes, enables the sharing of situation models and action plans, and mediates the cultural shaping of interacting minds.

We describe an ontology of philosophy that is designed to aid navigation through philosophical literature, including literature in the form of encyclopedia articles and textbooks and in both printed and digital forms. The ontology is designed also to serve integration and structuring of data pertaining to the philosophical literature, and in the long term also to support reasoning about the provenance and contents of such literature, by providing a representation of the philosophical domain that is oriented around what philosophical (...) literature is about.

We typically assume that the standard for what is beautiful lies in the eye of the beholder. Yet this is not the case when we consider morality; what we deem morally good is not usually a matter of opinion. Such thoughts push us toward being realists about moral properties, but a cogent theory of moral realism has long been an elusive philosophical goal. Paul Bloomfield here offers a rigorous defense of moral realism, developing an ontology for morality that models the (...) property of being morally good on the property of being physically healthy. The model is assembled systematically; it first presents the metaphysics of healthiness and goodness, then explains our epistemic access to properties such as these, adds a complementary analysis of the semantics and syntax of moral discourse, and finishes with a discussion of how we become motivated to act morally. Bloomfield closely attends to the traditional challenges facing moral realism, and the discussion nimbly ranges from modern medical theory to ancient theories of virtue, and from animal navigation to the nature of normativity. Maintaining a highly readable style throughout, Moral Reality yields one of the most compelling theories of moral realism to date and will appeal to philosophers working on issues in metaphysics or moral philosophy.

We argue that an understanding of the faculty of language requires substantial interdisciplinary cooperation. We suggest how current developments in linguistics can be profitably wedded to work in evolutionary biology, anthropology, psychology, and neuroscience. We submit that a distinction should be made between the faculty of language in the broad sense (FLB)and in the narrow sense (FLN). FLB includes a sensory-motor system, a conceptual-intentional system, and the computational mechanisms for recursion, providing the capacity to generate an infinite range of expressions (...) from a finite set of elements. We hypothesize that FLN only includes recursion and is the only uniquely human component of the faculty of language. We further argue that FLN may have evolved for reasons other than language, hence comparative studies might look for evidence of such computations outside of the domain of communication (for example, number, navigation, and social relations).

New forms of river management have emerged following widespread recognition of the environmental damage caused by attempts to harness and control rivers for navigation, consumptive water use and power generation. A dominant top-down engineering-based paradigm is being challenged by catchment-framed, ecosystem-based approaches which claim to place greater emphasis on participation and equity. However, there has been limited attention given to examining these claims, and principles of justice are frequently left unarticulated or embedded in what is still presented as an (...) essentially technical, outcome-driven management process. This paper examines the contribution of an environmental justice framework in articulating and explicating the ethical and political nature of decision making in stream rehabilitation practice. Particular attention is given to distributive, procedural and relational elements of justice, and to the limitations of an anthropocentric approach. A broader-based ecological justice framework is proposed. Several key issues in applying this framework are discussed, including the need for 'situated justice', for multiple voices to be heard, for dealing with unity and diversity at the catchment scales, and in integrating knowledge through genuine transdisciplinary research and practice.

The notion of conceptuality is still unclear and vague. I will present a definition of conceptual and nonconceptual representations that is grounded in different aspects of the representations' structures. This definition is then used to interpret empirical results from human and animal navigation. It will be shown, that the distinction between egocentric and allocentric spatial representations can be matched onto the conceptual vs. nonconceptual distinction. The phenomena discussed in spatial navigation are thereby put into a wider context of (...) cognitive abilities, which allows for new explanations of certain features of spatial representations and how they are linked to other capacities, like perception and reasoning.

Ethical challenges that arise within healthcare delivery institutions are currently categorized as either clinical or organizational, based on the type of issue. Despite this common binary issue-based methodology, empirical study and increasing academic dialogue indicate that a clear line cannot easily be drawn between organizational and clinical ethics. Disagreement around end-of-life treatments, for example, often spawn value differences amongst parties at both organizational and clinical levels and requires a resolution to address both the case at hand and large-scale underlying system-level (...) confounders. I refer to issues that contain elements of both clinical and organizational issues as hybrids and propose a new taxonomy to characterize hybrid cases. I contend that salient contextual features of an ethical issue, such as where it is identified, who it impacts and where it is ideally resolved in relation to its scope of impact, should inform procedure. Implementation of a Hybrid taxonomy viewing ethical issues as existing on a continuum furthers that end. The primary goals are to 1) systematize thinking about ethical issues that arise within healthcare delivery institutions and 2) allow the content of the ethical challenge to drive the process, rather than continuing to rely on the traditional binary issue-based choice. Failure to capture the complexity of hybrid situations perpetuates incomplete information and ultimately an inchoate resolution that creates more questions than answers. (shrink)
Biomedical research is increasingly a matter of the navigation through large computerized information resources deriving from functional genomics or from the biochemistry of disease pathways. To make such navigation possible, controlled vocabularies are needed in terms of which data from different sources can be unified. One of the most influential developments in this regard is the so-called Gene Ontology, which consists of controlled vocabularies of terms used by biologists to describe cellular constituents, biological processes and molecular functions, organized (...) into hierarchies via the relation of class subsumption. Here we seek to provide a rigorous account of the logic of classification that underlies GO and similar biomedical ontologies. Drawing on Aristotle, we develop a system of axioms and definitions for the treatment of biological classes and instances. (shrink)
‘‘COGNITIVE ECOLOGY’’ is a fruitful model for Shakespearian studies, early modern literary and cultural history, and theatrical history more widely. Cognitive ecologies are the multidimensional contexts in which we remember, feel, think, sense, communicate, imagine, and act, often collaboratively, on the fly, and in rich ongoing interaction with our environments. Along with the anthropologist Edwin Hutchins,1 we use the term ‘‘cognitive ecology’’ to integrate a number of recent approaches to cultural cognition: we believe these approaches offer productive lines of engagement (...) with early modern literary and historical studies.2 The framework arises out of our work in extended mind and distributed cognition.3 The extended mind hypothesis arose from a post-connectionist philosophy of cognitive science. This approach was articulated in Andy Clark’s Being There: Putting Brain, Body, and World Together Again, and further developed by Susan Hurley and Mark Rowlands, among others.4 The distributed cognition approach arose independently, from work in cognitive anthropology, HCI (Human-Computer Interaction), the sociology of education and work, and science studies. The principles of distributed cognition were articulated in Hutchins’s ethnography of navigation, Cogni- tion in the Wild,5 and developed by theorists such as David Kirsh and Lucy Suchman.6 These models share an anti-individualist approach to cognition. In all these views, mental activities spread or smear across the boundaries of skull and skin to include parts of the social and material world. In remembering, decision making, and acting, whether individually or in small groups, our complex and structured activities involve many distinctive dimensions: neural, affective, kines-. (shrink)

Determinism is the thesis that a future state is completely determined by a past state of something - thus its future course is fixed when the initial state is given. Before the discovery of quantum mechanics many people thought the universe was deterministic; rather like a huge clock. Indeterminacy is when something is NOT deterministic, that is the initial state does not completely determine all subsequent ones. Indeterminacy is an important topic and doubly so for those involved in social simulation. (...) Due my interest in these issues and the rather low level of insight provided by the chapters in this book, I will briefly summarise some of the issues as they relate to social simulation first, and relate it to the book later.

Abstract ?Theory of Mind? (ToM) is widely held to be ubiquitous in our navigation of the social world. Recently this standard view has been contested by phenomenologists and enactivists. Proponents of the ubiquity of ToM, however, accept and effectively neutralize the intuitions behind their arguments by arguing that ToM is mostly sub-personal. This paper proposes a similar move on behalf of the phenomenologists and enactivists: it offers a novel explanation of the intuition that ToM is ubiquitous that is compatible (...) with the rejection of this ubiquity. According to this explanation, we use ToM-talk primarily to model and thereby reconstruct non-mentalizing social-cognitive processes in order to explain our assessment of the behaviour of others. The intuition that ToM is ubiquitous is the result of mistaking the model for the real thing. This explanation is argued to be more complete than the ?ToM-ist? explanation of the intuition that ToM is not ubiquitous. (shrink)
According to Marin Cureau de La Chambre—steering a middleway between the Aristotelian and the Cartesian conception of the soul—everything that lives cognizes and everything that cognizes is alive. Cureau sticks with the general tripart distinction of vegetative, sensitive, and intellectual soul. Each part of the soul has its own cognition. Cognition is the way in which living beings regulate bodily equilibirum and environmental navigation. This regulative activity is gouverned by acquired or by innate images. Natural cognition (or instinct) is (...) cognition by innate images only. Cureau develops a highly originel theory of natural (or 'specialized') instinct. His theory attempts to explain five features of instinct (innateness, specialization, species-specifitiy, coerciveness, teleological nature). According to my interpretation, Cureau proposes a species of what is called a 'teleosemantic theory' of innate cognition. (shrink)
In the past, notions of embodiment have been applied to robotics mainly in the realm of very simple robots, and supporting low-level mechanisms such as dynamics and navigation. In contrast, most human-like, interactive, and socially adept robotic systems turn away from embodiment and use amodal, symbolic, and modular approaches to cognition and interaction. At the same time, recent research in Embodied Cognition (EC) is spanning an increasing number of complex cognitive processes, including language, nonverbal communication, learning, and social behavior. (...) This article suggests adopting a modern EC approach for autonomous robots interacting with humans. In particular, we present three core principles from EC that may be applicable to such robots: (a) modal perceptual representation, (b) action/perception and action/cognition integration, and (c) a simulation-based model of top-down perceptual biasing. We describe a computational framework based on these principles, and its implementation on two physical robots. This could provide a new paradigm for embodied human–robot interaction based on recent psychological and neurological findings. (shrink)
The Enlightenment was the age in which the world became modern, challenging tradition in favor of reason, freedom, and critical inquiry. While many aspects of the Enlightenment have been rigorously scrutinized—its origins and motivations, its principal characters and defining features, its legacy and modern relevance—the geographical dimensions of the era have until now largely been ignored. Placing the Enlightenment contends that the Age of Reason was not only a period of pioneering geographical investigation but also an age with spatial dimensions (...) to its content and concerns. Investigating the role space and location played in the creation and reception of Enlightenment ideas, Charles W. J. Withers draws from the fields of art, science, history, geography, politics, and religion to explore the legacies of Enlightenment national identity, navigation, discovery, and knowledge. Ultimately, geography is revealed to be the source of much of the raw material from which philosophers fashioned theories of the human condition. Lavishly illustrated and engagingly written, Placing the Enlightenment will interest Enlightenment specialists from across the disciplines as well as any scholar curious about the role geography has played in the making of the modern world.

Both direct, and evolved, behavior-based approaches to mobile robots have yielded a number of interesting demonstrations of robots that navigate, map, plan and operate in the real world. The work can best be described as attempts to emulate insect level locomotion and navigation, with very little work on behavior-based non-trivial manipulation of the world. There have been some behavior-based attempts at exploring social interactions, but these too have been modeled after the sorts of social interactions we see in insects. (...) But thinking how to scale from all this insect level work to full human level intelligence and social interactions leads to a synthesis that is very different from that imagined in traditional Artificial Intelligence and Cognitive Science. We report on work towards that goal. (shrink)
In Epistemic Cultures (1999), Karin Knorr Cetina argues that different scientific fields exhibit different epistemic cultures. She claims that in high energy physics (HEP) individual persons are displaced as epistemic subjects in favor of experiments themselves. In molecular biology (MB), by contrast, individual persons remain the primary epistemic subjects. Using Ed Hutchins' (1995) account of navigation aboard a traditional US Navy ship as a prototype, I argue that both HEP and MB exhibit forms of distributed cognition. That is, in (...) both fields cognition is distributed across individual persons and complex artifacts. The cognitive system producing the knowledge is heterogeneous. Nevertheless, in both fields we can reserve epistemic agency for the human components of these systems. We do not need to postulate new distributed cognitive agents, let alone ones exhibiting new forms of consciousness. (shrink)
We are currently witnessing the global diffusion of multiculturalism, both as a political discourse and as a set of international legal norms. States today are under increasing international scrutiny regarding their treatment of ethnocultural groups, and are expected to meet evolving international standards regarding the rights of indigenous peoples, national minorities, and immigrants. This phenomenon represents a veritable revolution in international relations, yet has received little public or scholarly attention. In this book, Kymlicka examines the factors underlying this change, and (...) the challenges it raises. Against those critics who argue that multiculturalism is a threat to universal human rights, Kymlicka shows that the sort of multiculturalism that is being globalized is inspired and constrained by the human rights revolution, and embedded in a framework of liberal-democratic values. However, the formulation and implementation of these international norms has generated a number of dilemmas. The policies adopted by international organizations to deal with ethnic diversity are driven by conflicting impulses. Pessimism about the destabilizing consequences of ethnic politics alternates with optimism about the prospects for a peaceful and democratic form of multicultural politics. The result is often an unstable mix of paralyzing fear and naïve hope, rooted in conflicting imperatives of security and justice. Moreover, given the enormous differences in the characteristics of minorities (eg., their size, territorial concentration, cultural markers, historic relationship to the state), it is difficult to formulate standards that apply to all groups. Yet attempts to formulate more targeted norms that apply only to specific categories of minorities (eg., "indigenous peoples" or "national minorities") have proven controversial and unstable. Kymlicka examines these dilemmas as they have played out in both the theory and practice of international minority rights protection, including recent developments regarding the rights of national minorities in Europe, the rights of indigenous peoples in the Americas, as well as emerging debates on multiculturalism in Asia and Africa.

We present a skill learning model CLARION. Different from existing models of high-level skill learning that use a topdown approach (that is, turning declarative knowledge into procedural knowledge), we adopt a bottom-up approach toward low-level skill learning, where procedural knowledge develops first and declarative knowledge develops later. CLAR- ION is formed by integrating connectionist, reinforcement, and symbolic learning methods to perform on-line learning. We compare the model with human data in a minefield navigation task. A match between the model (...) and human data is found in several respects. (shrink)
Very encouraging results have been obtained from a new program that derives a dense three-dimensional evidence grid representation of a robot's surroundings from wide-angle stereoscopic images. The pro gram adds several spatial rays of evidence to a grid for each of about 2,500 local image features chosen per stereo pair. It was used to construct a 256x256x64 grid, representing 6 by 6 by 2 meters, from a hand- collected test set of twenty stereo image pairs of an office scene. Fifty (...) nine stereo pairs of an 8 by 8 meter laboratory were also processed. The positive (probably occupied) cells of the grids, viewed in perspec tive, resemble dollhouse scenes. Details as small as the curvature of chair armrests are discernible. The processing time, on a 100 MIPS Sparc 20, is less than five seconds per stereo pair, and total memory is under 16 megabytes. The results seem abundantly adequate for very reliable navigation of freely roaming mobile robots, and plausibly adequate for shape identification of objects bigger than 10 centimeters. The program is a first proof of concept, and awaits optimizations, enhancements, variations, extensions and applications. (shrink)
The central paradigm of arti?cial intelligence is rapidly shifting toward biological models for both robotic devices and systems performing such critical tasks as network management, vehicle navigation, and process control. Here we use a recent mathematical analysis of the necessary conditions for consciousness in humans to explore likely failure modes inherent to a broad class of biologically inspired computing machines. Analogs to developmental psychopathology, in which regulatory mechanisms for consciousness fail progressively and subtly understress, and toinattentional blindness, where a (...) narrow 'syntactic band pass' de?ned by the rate distortion manifold of conscious attention results in pathological ?xation, seem inevitable. Similar problems are likely to confront other possible architectures, although their mathematical description may be far less straightforward. Computing devices constructed on biological paradigms will inevitably lack the elaborate, but poorly understood, system of control mechanisms which has evolved over the last few hundred million years to stabilize consciousness in higher animals. This will make such machines prone to insidious degradation, and, ultimately, catastrophic failure. (shrink)
This paper reports the findings from an interconnected set of experiments designed to assess children’s knowledge of the semantic interactions between negation and quantified NPs. Our main finding is that young children, unlike adults, systematically interpret these elements on the basis of their position in overt syntax. We argue that this observation can be derived from an interplay between fundamental properties of universal grammar and basic learning principles. We show that even when children’s semantic knowledge appears to differ from that (...) of adults, the observed differences.. (shrink)
The debate about what constitutes the discipline of ethics and who qualifies as an ethics consultant is linked unavoidably to a debate that is potentiated by the reality of a rapidly changing and high-stakes health care consultation marketplace. Who we are and what we can offer to the moral gesture that is medicine is shaped by our fundamental understanding of the place of expert knowledge in the transformation of social reality. The struggle for self-definition is particularly freighted since clinical ethics (...) consultation aspires to be more than academic contemplation. Two recent books (Ethics Consultation by John La Puma and David Schiedermayer and The Health Care Ethics Consultant: A Practical Guide, edited by Francoise Baylis) exemplify the two most popular but most widely divergent positions on these issues. We argue that while useful, neither book addresses fully the particular and distinct role of the professional ethicist. (shrink)
Both direct, and evolved, behavior-based approaches to mobile robots have yielded a number of interesting demonstrations of robots that navigate, map, plan and operate in the real world. The work can best be described as attempts to emulate insect level locomotion and navigation, with very little work on behavior-based non-trivial manipulation of the world. There have been some behavior-based attempts at exploring social interactions, but these too have been modeled after the sorts of social interactions we see in insects. (...) But thinking how to scale from all this insect level work to full human level intelligence and social interactions leads to a synthesis that is very di erent from that imagined in traditional Arti cial Intelligence and Cognitive Science. We report on work towards that goal. (shrink)
The scientific worldview is based on laws, which are supposed to be certain, objective, and independent of time and context. The narrative worldview found in literature, myth and religion, is based on stories, which relate the events experienced by a subject in a particular context with an uncertain outcome. This paper argues that the concept of “agent”, supported by the theories of evolution, cybernetics and complex adaptive systems, allows us to reconcile scientific and narrative perspectives. An agent follows a course (...) of action through its environment with the aim of maximizing its fitness. Navigation along that course combines the strategies of regulation, exploitation and exploration, but needs to cope with often-unforeseen diversions. These can be positive (affordances, opportunities), negative (disturbances, dangers) or neutral (surprises). The resulting sequence of encounters and actions can be conceptualized as an adventure. Thus, the agent appears to play the role of the hero in a tale of challenge and mystery that is very similar to the "monomyth", the basic storyline that underlies all myths and fairy tales according to Campbell [1949]. This narrative dynamics is driven forward in particular by the alternation between prospect (the ability to foresee diversions) and mystery (the possibility of achieving an as yet absent prospect), two aspects of the environment that are particularly attractive to agents. This dynamics generalizes the scientific notion of a deterministic trajectory by introducing a variable “horizon of knowability”: the agent is never fully certain of its further course, but can anticipate depending on its degree of prospect.

Information management systems improve the retention of information in large collections. As such they act as memory prostheses, implying an ideal basis in human memory models. Since humans process information by association, and situate it in the context of space and time, systems should maximize their effectiveness by mimicking these functions. Since human attentional capacity is limited, systems should scaffold cognitive efforts in a comprehensible manner. We propose the Principles of Mnemonic Associative Knowledge (P-MAK), which describes a framework for semantically (...) identifying, organizing, and retrieving information, and for encoding episodic events by time and stimuli. Inspired by prominent human memory models, we propose associative networks as a preferred representation. Networks are ideal for their parsimony, flexibility, and ease of inspection. Networks also possess topological properties—such as clusters, hubs, and the small world—that aid analysis and navigation in an information space. Our cognitive perspective addresses fundamental problems faced by information management systems, in particular the retrieval of related items and the representation of context. We present evidence from neuroscience and memory research in support of this approach, and discuss the implications of systems design within the constraints of P-MAK’s principles, using text documents as an illustrative semantic domain.

Human social coordination is often mediated by language. Through verbal dialogue, people direct each other's attention to properties of their shared environment, they discuss how to jointly solve problems, share their introspections, and distribute roles and assignments. In this article, we propose a dynamical framework for the study of the coordinative role of language. Based on a review of a number of recent experimental studies, we argue that shared symbolic patterns emerge and stabilize through a process of local reciprocal linguistic (...) alignment. Such patterns in turn come to facilitate and refine social coordination by enabling the alignment, joint construction and navigation of conceptual models and actions. Implications of the framework are illustrated and discussed in relation to a case study where dyads of interlocutors interact verbally to reach joint decisions in a perceptual discrimination task. Keywords: social coordination; language; communication; linguistic alignment; symbolic patterns; affordances; emergence; evolution; adaptivity; interaction. (shrink)
This paper presents an autonomous vision-based obstacle avoidance system. The system consists of three independent vision modules for obstacle detection, each of which is computationally simple and uses a di erent criterion for detection purposes. These criteria are based on brightness gradients, RGB Red, Green, Blue color, and HSV Hue, Saturation, Value color, respectively. Selection of which modules are used to command the robot proceeds exclusively from the outputs of the modules themselves. The system is implemented on a small monocular (...) mobile robot and uses very low resolution images. It has been tested for over 200 hours in diverse environments. Keywords: Vision-based navigation, space exploration, modular design, reactive control, unstructured terrain. (shrink)
This article examines implications of computer-sifted information: What happens when that information is reshuffled and used for other purposes than originally intended? Historical concepts of the philosophy of privacy are examined, essentially to demonstrate that a lack of clear precedent further confuses a fast-changing situation. The author argues that, a 100-odd years ago, advancing media technology prompted Louis Brandeis to proclaim a right to be let alone - but in the intervening years we have not been particularly effective in developing (...) proactive ethics and policy to deal with privacy issues. One case, a bill to restrict access to motor vehicle information, is cited as an example of proactive legislation; without advocating specific legislation, the author calls for increased foresight in the issue of technology and privacy.

The project is funded by the Office of Naval Research under a contract entiltled Underwater Robots. The effort is interesting in its own right, and complements projects involving underwater vehicles such as those at the University of New Hampshire and the Naval Ocean Systems Center in San Diego. These other efforts are interesting to us, but we feel they are incomplete. Their current control systems are very simple, typically incorporating quite small programs on one or a few microprocessors and implementing (...) simple dead reckoning navigation or terrain following behavior.

A large interest has been dedicated in recent years to the study of models for textual databases amenable to an effective integration of search and navigation functions. In the field of legal databases the need for sophisticated models is emphasised by the need to relate and combine in an effective way different types of texts, in order to solve legal problems.In our research we have analysed several existing models, each providing specific benefits and exhibiting corresponding limitations, under both a (...) functional and economical viewpoint.

top-down approach (that is, turning declarative knowledge into procedural knowledge), we adopt a bottom-up approach toward lowlevel skill learning, where procedural knowledge develops rst and declarative knowledge develops from it. Clarionwhich follows this approach is formed by integrating connectionist, reinforcement, and symbolic learning methods to perform on-line learning. We compare the model with human data in a mine eld navigation task. A match between the model and human data is observed in several comparisons.
Multimedia technology offers instructional designers an unprecedented opportunity to create richly interactive learning environments. With greater design freedom comes complexity. The standard answer to the problems of too much choice, disorientation, and complex navigation is thought to lie in the way we design interactivity in a system. Unfortunately, the theory of interactivity is at an early state of development. After critiquing the decision cycle model of interaction—the received theory in human computer interaction—I present arguments and observational data to show (...) that humans have several ways of interacting with their environments, which resist accommodation in the decision cycle model. These additional ways of interacting include: preparing the environment, maintaining the environment, and reshaping the cognitive congeniality of the environment. Understanding how these actions simplify the computational complexity of our mental processes is the first step in designing the right sort of resources and scaffolding necessary for tractable learner controlled learning environments.

An explicit linking of the minutiae of everyday parenting practices and the good of society as a whole has been a feature of government policy. The state has taken responsibility for instilling the right parenting skills to deal with what is said to be the societal fall-out of contemporary and family change. ?Knowledge? about parenting is seen as a resource that parents must access in order to fulfil their moral duty as good parents. In this policy portrait, caring for children (...) is posed as a classless and gender-neutral activity. A key theme of this article is that parents from different social class groups are positioned and understand themselves in quite distinct ways in relation to parenting skills advice and expert intervention into their family and home lives. We take a ?relational? perspective to show how mothers and fathers from different social class groups see themselves, and are located by policy and practice, as clients or consumers, and as commonplace or pioneers, in relation to parenting support for themselves and the education system for their children. We identify the lived gendered and classed disparities of power, and associated moral worth, attached to particular parenting practices. (shrink)

This study is an analysis of 186 psychologists' attitudes on what constitutes ethical practice when counseling clients who present with a range of concerns related to their experience of same-sex attraction and behavior. Three different groups of psychologists were surveyed: generalists, specialists in gay and lesbian issues, and religiously affiliated psychologists. Participants also rated the effectiveness of several professional experiences in providing education, direction, sanctions, or support to regulate the practice of counseling nonheterosexual clients. Significant group differences were found regarding (...) what is considered best, acceptable, and unacceptable practice with clients presenting with same-sex attraction issues. Significant differences were also found among the three groups in what respondents rated as effective elements of their clinical experience. Keywords: gay, lesbian, religion, survey. (shrink)
In this paper, I outline several methodological questions that we need to confront. The chief question is how can we identify the nature of technological change and its varied cultural consequences—including social, political, institutional, and economic dimensions—when our different research methods, using distinct ‘levels’ or ‘scales’ of analysis, yield contradictory results. What can we say, in other words, when our findings about technology follow from the framings of our inquiries? In slightly different terms, can we combine insights from the fine-grained (...) “social shaping of technology” as well as from complementary approaches accenting the “technological shaping of society?” As a way forward, I will suggest conducting multi-scale inquiries into the processes of technological and cultural change. This will involve recognizing and conceptualizing the analytical scales or levels on which we conduct inquiry (very roughly, micro, meso, macro) as well as outlining strategies for moving within and between these scales or levels. Of course we want and need diverse methodologies for analyzing technology and culture. I find myself in sympathy with geographer Brenner (New state spaces: urban governance and the rescaling of statehood, 2004, p. 7), who aspires to a “theoretically precise yet also historically specific conceptualization of [technological change] as a key dimension of social, political and economic life.”.

Early vision provides general information about the environment that can be used for motor control or navigation and more specialized information that can be used for object recognition. The general information is likely to be insensitive to cognitive factors, but this may not be entirely true for the information used in model-based recognition.
Neural organization achieves its stated goal to “show how theory and experiment can supplement each other in an integrated, evolving account of structure, function, and dynamics” (p. ix), showing in a variety of contexts – from olfactory processing to spatial navigation, motor learning and more – how function may be realized in the neural tissue, with explanatory and predictive neural network models providing a cornerstone in this approach.
Polygyny does not necessarily entail sexual selection of men. All factors that affect the operational sex ratio must be considered. Data from contemporary hunter-gatherers indicate higher mortality rates in men than in women, and lost female reproductive time. If sexual selection did occur in ancestral hunter-gatherers, it was probably men selecting women and not women selecting men.
The evidence grid representation was formulated at the CMU Mobile Robot Laboratory in 1983 to turn wide angle range measurements from cheap mobile robot-mounted sonar sensors into detailed spatial maps. It accumulates diffuse evidence about the occupancy of a grid of small volumes of nearby space from individual sensor readings into increasingly confident and detailed maps of a robot's surroundings. It worked surprisingly well in first implementation for sonar navigation in cluttered rooms. In the past decade its use has (...) been extended to range measurements from stereoscopic vision and other sensors, sonar in very difficult specular environments, and other contexts. The most dramatic extension yet, from 2D grid maps with thousands of cells to 3D grids with millions, is underway. (shrink)
Language is a rewarding field if you are in the prediction business. A reader who is fluent in English and who knows how academic papers are typically structured will readily come up with several possible guesses as to where the title of this section could have gone, had it not been cut short by the ellipsis. Indeed, in the more natural setting of spoken language, anticipatory processing is a must: performance of machine systems for speech interpretation depends critically on the (...) availability of a good predictive model of how utterances unfold in time (Baker, 1975; Jelinek, 1990; Goodman, 2001), and there is strong evidence that prospective uncertainty affects human sentence processing too (Jurafsky, 2003; Hale, 2006; Levy, 2008). The human ability to predict where the current utterance is likely to be going is just another adaptation to the general pressure to anticipate the future (Hume, 1748; Dewey, 1910; Craik, 1943), be it in perception, thinking, or action, which is exerted on all cognitive systems by evolution (Dennett, 2003). Look-ahead in language is, however, special in one key respect: language is a medium for communication, and in communication the most interesting (that is, informative) parts of the utterance that the speaker is working through are those that cannot be predicted by the listener ahead of time.

Software application ontologies have the potential to become the keystone in state-of-the-art information management techniques. It is expected that these ontologies will support the sort of reasoning power required to navigate large and complex terminologies correctly and efficiently. Yet, there is one problem in particular that continues to stand in our way. As these terminological structures increase in size and complexity, and the drive to integrate them inevitably swells, it is clear that the level of consistency required for such (...) class='Hi'>navigation will become correspondingly difficult to maintain. While descriptive semantic representations are certainly a necessary component to any adequate ontology-based system, so long as ontology engineers rely solely on semantic information, without a sound ontological theory informing their modeling decisions, this goal will surely remain out of reach. In this paper we describe how Language and Computing nv (L&C), along with The Institute for Formal Ontology and Medical Information Sciences (IFOMIS), are working towards developing and implementing just such a theory, combining the open software architecture of L&C’s LinkSuiteTM with the philosophical rigor of IFOMIS’s Basic Formal Ontology. In this way we aim to move beyond the more or less simple controlled vocabularies that have dominated the industry to date. (shrink)
Patrick O'Brian, the Aubrey-Maturin Series of twenty novels (Norton, 1970-1999). My appreciation written for WIRED magazine: "I re-read this extraordinary series of novels because of the depth of portrayal of the major and minor characters, but also because they teach me so much about what science and technology were like two centuries ago. O'Brian shows you the world-that-was through the eyes of a Tory naval captain (Jack Aubrey), at sea since the age of 12, working his way up to admiral, (...) dealing with the height of 18th-century technology (sailing ships and celestial navigation). I identify more strongly with his liberally-educated, physician-scientist friend (Stephen Maturin), who went to medical school in Paris during the French Revolution. You see natural history turning into a biological science, bleeding-and-purging medicine starting to learn some physiology -- and, because Maturin is also an intelligence agent for the Admiralty, you see statecraft at work during the Napoleonic Wars. These books strongly remind you about what scientific ignorance and social conventions can do to your mindset, and how the future will likely judge us as well." -- William H.

Written with poignancy and compassion, Do We Still Need Doctors? is a personal account from the front lines of the moral and political battles that are reshaping America's health care system. Using compelling firsthand experiences, clinical vignettes, and moral arguments, John D. Lantos, a pediatrician, asks whether, as we proceed with the redesign of our health care system, doctors will -- or should -- continue to fulfill the roles and responsibilities that they have in the past. Interspersing moving personal stories (...) of his young patients suffering from AIDS, cancer, and other chronic or terminal illnesses with his own stirring dilemmas of truth telling, creative navigation of HMO bureaucracy, and reflections on the identity crisis of medical education, Dr. Lantos reveals how changes in out health care system and new technologies are fostering new ways of understanding and responding to illness. He taps into the public's sense of wanting doctors and hospitals to do something other than what they do now and the frustrating disagreement about what they should do in the future. (shrink)
Against any obscurantist stand, denying the interest of natural sciences for the comprehension of human meaning and language, but also against any reductionist hypothesis, frustrating the specificity of the semiotic point of view on nature, the paper argues that the deepest dynamic at the basis of meaning consists in its being a mechanism of ‘potentiality navigation’ within a universe generally characterized by motility. On the one hand, such a hypothesis widens the sphere of meaning to all beings somehow endowed (...) with the capacity of moving and/or perceiving movement. On the other hand, through a new evolutionist interpretation of the concept of generativity, such a hypothesis preserves the peculiarity of human meaning, meant as essentially founded on a certain intuition of infinity. Two corollaries stem from this hypothesis: first, religiosity can be considered as a matrix of grammars of infinity, aiming at regimenting its flight of potentialities. Second, non-genetic transmission of cultural information exerts determinant influence also at the level of that very deep mechanism of the human predicament that is the cognitive navigation of motor potentialities. A re-reading of the structuralist epistemology, scientific literature on the nervous cells of jellyfish, and some recent experiments on the mirror neurons of dancers, as well as certain intuitions of Teilhard de Chardin, are the main arguments of the paper.

The author argues that the new digital possibilities in scientific communication do not imply, by any means, that many old requirements are becoming dispensable. The essential elements of the system, such as quality assurance, authenticity, orientation and navigation will still demand considerable expense. The overall system costs will rather be higher in a hybrid system. In the second part of his lecture, the author discusses the two fundamentally different open access models, the Golden Road, which is supposed to be (...) able to operate, eventually, without any publishers, and the Green Road, whose functioning is based on primary publication through publishing houses. Finally, the basic issue of the indispensable qualitative stratigraphy of scientific documents is addressed. For this, the published journals, which also provide topical focus and, thus, orientation as well as active marketing in terms of optimal diffusion, still are a very capable tool. It is questionable to what extent these tasks could be fulfilled by university-based repositories. The publishing houses, on the other hand, have a proven track record of providing a wide range of useful value-adding services in digital publishing. (shrink)
Implicit and explicit filling-in phenomena should be distinguished. Blind spot phenomena and mechanisms of boundary completion can be accounted for by implicit filling-in. Surface regions are “painted” with perceptual quantities, such as brightness, by explicit filling-in. “Filling-in” and “finding-out” relate to different computational tasks. Mechanisms of purposive computation (e.g., for navigation) evaluate local measurements, thus “finding out”; whereas mechanisms for grasping might require passive reconstruction, thus “filling in.”.
Electronic publications are not accessible without technical aids and need constant, time consuming attention; a look back at the data media and data formats utilized in the past 25Â years illustrates this. Recently, an increasing number of conferences and studies address the problem. Use of standard data formats, media and platform independence of data, as well as data centering instead of process centering are requirements for long-term availability. For the humanities, texts are not only the sources of information but also (...) objects of scholarly investigation. Therefore publication in a presentation format only is not sufficient. In addition to more sophisticated tools for analysis, search and navigation, a form of publication is required which does not focus on layout but gives easy access to the content and structure of the published document. Both for the creation and the scholarly evaluation of such documents, tools are required which offer additional functions compared to those provided by commercial publication and access tools. The necessary flexibility is guaranteed by the provision of basic functions of text data processing which do not anticipate or preclude any particular questions. This is illustrated by examples for the evaluation and preparation of digital texts. (shrink)
Kant argued that Euclidean geometry is synthesized on the basis of an a priori intuition of space. This proposal inspired much behavioral research probing whether spatial navigation in humans and animals conforms to the predictions of Euclidean geometry. However, Euclidean geometry also includes concepts that transcend the perceptible, such as objects that are infinitely small or infinitely large, or statements of necessity and impossibility. We tested the hypothesis that certain aspects of nonperceptible Euclidian geometry map onto intuitions of space (...) that are present in all humans, even in the absence of formal mathematical education. Our tests probed intuitions of points, lines, and surfaces in participants from an indigene group in the Amazon, the Mundurucu, as well as adults and age-matched children controls from the United States and France and younger US children without education in geometry. The responses of Mundurucu adults and children converged with that of mathematically educated adults and children and revealed an intuitive understanding of essential properties of Euclidean geometry. For instance, on a surface described to them as perfectly planar, the Mundurucu's estimations of the internal angles of triangles added up to ∼180 degrees, and when asked explicitly, they stated that there exists one single parallel line to any given line through a given point. These intuitions were also partially in place in the group of younger US participants. We conclude that, during childhood, humans develop geometrical intuitions that spontaneously accord with the principles of Euclidean geometry, even in the absence of training in mathematics. (shrink)
After critical appraisal of mathematical and biological characteristics of the model, we discuss how a classical hippocampal neural network expresses functions similar to those of the chaotic model, and then present an alternative stimulus-driven chaotic random recurrent neural network (RRNN) that learns patterns as well as sequences, and controls the navigation of a mobile robot.
