This paper outlines an original interactivist-constructivist approach to modelling intelligence and learning as a dynamical embodied form of adaptiveness and explores some applications of I-C to understanding the way cognitive learning is realized in the brain. Two key ideas for conceptualizing intelligence within this framework are developed. These are: intelligence is centrally concerned with the capacity for coherent, context-sensitive, self-directed management of interaction; and the primary model for cognitive learning is anticipative skill construction. Self-directedness is a capacity for integrative process (...) modulation which allows a system to "steer" itself through its world by anticipatively matching its own viability requirements to interaction with its environment. Because the adaptive interaction processes required of intelligent systems are too complex for effective action to be prespecified learning is an important component of intelligence. A model of self-directed anticipative learning is formulated based on interactive skill construction, and argued to constitute a central constructivist process involved in cognitive development. SDAL illuminates the capacity of intelligent learners to start with the vague, poorly defined problems typically posed in realistic learning situations and progressively refine them, transforming them into problems with sufficient structure to guide the construction of a solution. Finally, some of the implications of I-C for modelling of the neuronal basis of intelligence and learning are explored; in particular, Quartz and Sejnowski's recent neural constructivism paradigm, enriched by Montague and Sejnowski's dopaminergic model of anticipative-predictive neural learning, is assessed as a promising, but incomplete, contribution to this approach. The paper concludes with a fourfold reflection on the divergence in cognitive modelling philosophy between the I-C and the traditional computational information processing approaches. (shrink)

Both natural and engineered systems are fundamentally dynamical in nature: their defining properties are causal, and their functional capacities are causally grounded. Among dynamical systems, an interesting and important sub-class are those that are autonomous, anticipative and adaptive (AAA). Living systems, intelligent systems, sophisticated robots and social systems belong to this class, and the use of these terms has recently spread rapidly through the scientific literature. Central to understanding these dynamical systems is their complicated organisation and their consequent capacities for (...) re- and self- organisation. But there is at present no general analysis of these capacities or of the requisite organisation involved. We define what distinguishes AAA systems from other kinds of systems by characterising their central properties in a dynamically interpreted information theory. (shrink)

Donald Campbell has long advocated a naturalist epistemology based on a general selection theory, with the scope of knowledge restricted to vicarious adaptive processes. But being a vicariant is problematic because it involves an unexplained epistemic relation. We argue that this relation is to be explicated organizationally in terms of the regulation of behavior and internal state by the vicariant, but that Campbell's selectionist approach can give no satisfactory account of it because it is opaque to organization. We show how (...) organizational constraints and capacities are crucial to understanding both evolution and cognition and conclude with a proposal for an enriched, generalized model of evolutionary epistemology that places high-order regulatory organization at the center.

In this paper, we outline a theory of the nature of self-directed agents. What is distinctive about self-directed agents is their ability to anticipate interaction processes and to evaluate their performance, and thus their sensitivity to context. They can improve performance relative to goals, and can, in certain instances, construct new goals. We contrast self-directedness with reactive action processes that are not modifiable by the agent, though they may be modified by supra-agent processes such as populational adaptation or external design.Self-directedness (...) lies at the nexus of issues concerning the evolution and nature of intentionality, intelligence, and agency. It provides some insight into the evolution of intelligence because it helps explain how organisms are able to manage variable interaction processes, e.g., a hunting strategy that varies with prey type, ground condition, and hunger level. Simple self-directed organisms like bumblebees manage variability in one or a few dimensions. (shrink)

Background: Debates over legalisation of physician-assisted suicide or euthanasia often warn of a “slippery slope”, predicting abuse of people in vulnerable groups. To assess this concern, the authors examined data from Oregon and the Netherlands, the two principal jurisdictions in which physician-assisted dying is legal and data have been collected over a substantial period.Methods: The data from Oregon comprised all annual and cumulative Department of Human Services reports 1998–2006 and three independent studies; the data from the Netherlands comprised all four (...) government-commissioned nationwide studies of end-of-life decision making and specialised studies. Evidence of any disproportionate impact on 10 groups of potentially vulnerable patients was sought.Results: Rates of assisted dying in Oregon and in the Netherlands showed no evidence of heightened risk for the elderly, women, the uninsured , people with low educational status, the poor, the physically disabled or chronically ill, minors, people with psychiatric illnesses including depression, or racial or ethnic minorities, compared with background populations. The only group with a heightened risk was people with AIDS. While extralegal cases were not the focus of this study, none have been uncovered in Oregon; among extralegal cases in the Netherlands, there was no evidence of higher rates in vulnerable groups.Conclusions: Where assisted dying is already legal, there is no current evidence for the claim that legalised PAS or euthanasia will have disproportionate impact on patients in vulnerable groups. Those who received physician-assisted dying in the jurisdictions studied appeared to enjoy comparative social, economic, educational, professional and other privileges. (shrink)

Objective: The field of clinical ethics is relatively new and expanding. Best practices in clinical ethics against which one can benchmark performance have not been clearly articulated. The first step in developing benchmarks of clinical ethics services is to identify and understand current practices.Design and setting: Using a retrospective case study approach, the structure, activities, and resources of nine clinical ethics services in a large metropolitan centre are described, compared, and contrasted.Results: The data yielded a unique and detailed account of (...) the nature and scope of clinical ethics services across a spectrum of facilities. General themes emerged in four areas—variability, visibility, accountability, and complexity. There was a high degree of variability in the structures, activities, and resources across the clinical ethics services. Increasing visibility was identified as a significant challenge within organisations and externally. Although each service had a formal system for maintaining accountability and measuring performance, differences in the type, frequency, and content of reporting impacted service delivery. One of the most salient findings was the complexity inherent in the provision of clinical ethics services, which requires of clinical ethicists a broad and varied skill set and knowledge base. Benchmarks including the average number of consults/ethicist per year and the hospital beds/ethicist ratio are presented.Conclusion: The findings will be of interest to clinical ethicists locally, nationally, and internationally as they provide a preliminary framework from which further benchmarking measures and best practices in clinical ethics can be identified, developed, and evaluated.

I argue that recent advances in developmental biology demonstrate the inadequacy of suborganismal mechanism. The category of the organism, construed as a ’natural purpose’ should play an ineliminable role in explaining ontogenetic development and adaptive evolution. According to Kant the natural purposiveness of organisms cannot be demonstrated to be an objective principle in nature, nor can purposiveness figure in genuine explain. I attempt to argue, by appeal to recent work on self-organization, that the purposiveness of organisms is a natural phenomenon (...) and, by appeal to the apparatus of invariance explanation, that biological purposiveness provides genuine, ineliminable biological explanations.

Although rationing of scarce health-care resources is inevitable in clinical practice, there is still limited and scattered information about how physicians perceive and execute this bedside rationing (BSR) and how it can be performed in an ethically fair way. This review gives a systematic overview on physicians’ perspectives on influences, strategies, and consequences of health-care rationing. Relevant references as identified by systematically screening major electronic databases and manuscript references were synthesized by thematic analysis. Retrieved studies focused on themes that fell (...) under three major headings: (i) conditions and influences of BSR, (ii) strategies of BSR, and (iii) consequences of BSR. The range of themes indicates that physicians’ rationing behavior is highly variable, strongly influenced by context-related factors, and consists mainly of implicit rationing strategies. Torn between patient advocacy and the obligation to contain costs, physicians experience various role conflicts. The development of explicit rationing strategies seems necessary to avoid arbitrary BSR and allow a fair allocation of health-care resources. (shrink)

What determines whether an action is right or wrong? Morality, Rules, and Consequences: A Critical Reader explores for students and researchers the relationship between consequentialist theory and moral rules. Most of the chapters focus on rule consequentialism or on the distinction between act and rule versions of consequentialism. Contributors, among them the leading philosophers in the discipline, suggest ways of assessing whether rule consequentialism could be a satisfactory moral theory. These essays, all of which are previously unpublished, provide students in (...) moral philosophy with essential material and ask key questions on just what the criteria for an adequate moral theory might be.

Recent studies using functional magnetic resonance imaging of patients in a vegetative state have raised the possibility that such patients retain some degree of consciousness. In this paper, the ethical implications of such findings are outlined, in particular in relation to decisions about withdrawing life-sustaining treatment. It is sometimes assumed that if there is evidence of consciousness, treatment should not be withdrawn. But, paradoxically, the discovery of consciousness in very severely brain-damaged patients may provide more reason to let them die. (...) Although functional neuroimaging is likely to play an increasing role in the assessment of patients in a vegetative state, caution is needed in the interpretation of neuroimaging findings. (shrink)

The Greeks and Romans have been charged with destroying the ecosystems within which they lived. In this book, however, M. D. Usher argues rather that we can find in their lives and thought the origin of modern ideas about systems and sustainability, important topics for humans today and in the future. With chapters running the gamut of Greek and Roman experience – from the Presocratics and Plato to Roman agronomy and the Benedictine Rule – Plato's Pigs brings together unlikely bedfellows, (...) both ancient and modern, to reveal surprising connections. Lively prose and liberal use of anecdotal detail, including an afterword about the author's own experiments with sustainable living on his sheep farm in Vermont, add a strong authorial voice. In short, this is a unique, first-of-its-kind book that is sure to be of interest to anyone working in Classics, environmental studies, philosophy, ecology, or the history of ideas. (shrink)

Recent years have been blessed with an abundance of logical systems, arising from a multitude of applications. A logic can be characterised in many different ways. Traditionally, a logic is presented via the following three components: 1. an intuitive non-formal motivation, perhaps tie it in to some application area 2. a semantical interpretation 3. a proof theoretical formulation. There are several types of proof theoretical methodologies, Hilbert style, Gentzen style, goal directed style, labelled deductive system style, and so on. The (...) tableau methodology, invented in the 1950s by Beth and Hintikka and later per fected by Smullyan and Fitting, is today one of the most popular, since it appears to bring together the proof-theoretical and the semantical approaches to the pre of a logical system and is also very intuitive. In many universities it is sentation the style first taught to students. Recently interest in tableaux has become more widespread and a community crystallised around the subject. An annual tableaux conference is being held and proceedings are published. The present volume is a Handbook a/Tableaux pre senting to the community a wide coverage of tableaux systems for a variety of logics. It is written by active members of the community and brings the reader up to frontline research. It will be of interest to any formal logician from any area. (shrink)

Citizens today are increasingly expected to be knowledgeable about and prepared to engage with biomedical knowledge. In this article, I wish to reframe this ‘public understanding of science’ project, and place fresh emphasis on public understandings of research: an engagement with the everyday laboratory practices of biomedicine and its associated ethics, rather than with specific scientific facts. This is not based on an assumption that non-scientists are ‘ignorant’ and are thus unable to ‘appropriately’ use or debate science; rather, it is (...) underpinned by an empirically-grounded observation that some individuals may be unfamiliar with certain specificities of particular modes of research and ethical frameworks, and, as a consequence, have their autonomy compromised when invited to participate in biomedical investigations. Drawing on the perspectives of participants in my own sociological research on the social and ethical dimensions of neuroscience, I argue that public understanding of biomedical research and its ethics should be developed both at the community level and within the research moment itself in order to enhance autonomy and promote more socially robust science. Public bioethics will have to play a key role in such an endeavour, and indeed will contribute in important ways to the opening up of new spaces of symmetrical engagement between bioethicists, scientists and wider publics—and hence to the democratisation of the bioethical enterprise.

It is not certain when or by whom S0009838800011642_inline1 and S0009838800011642_inline2 were first technically distinguished as genus and species. The distinction does not appear in Plato's extant writings, whereas Aristotle seems to take it for granted in the Topics, which is usually regarded as among his earliest treatises. In his dialogues Plato seems able to use S0009838800011642_inline3 interchangeably to denote any group or division in a diairesis, including the group that is to be divided.

While much has been written on the cultural and intellectual antecedents that gave rise to Carolus Linnaeus?s herbarium and his Systema Naturae, the tools that he used to transform his raw observations into nomenclatural terms and categories have been neglected. Focusing on the Philosophia Botanica, the popular classification handbook that he published in 1751, it can be shown that Linnaeus cleverly ordered and reordered the work by employing commonplacing techniques that had been part of print culture since the Renaissance. Indeed, (...) the functional adaptability of commonplace heads allowed him to split and combine the book?s chapters and tables and played a notable conceptual role in the way in which he spatialized words and, to a certain extent, specimens.

We report the results of a randomized trial to assess the impact of an innovative ethics curriculum on the knowledge and confidence of 85 medical house officers in a university hospital programme, as well as their responses to a simulated clinical case. Twenty-five per cent of the house officers received a lecture series, 25 per cent received lectures and case conferences, with an ethicist in attendance, and 50 per cent served as controls. A post-intervention questionnaire was administered. Knowledge scores did (...) not differ among the groups. Confidence regarding ethical issues was significantly greater in the aggregate intervention group compared to the control group. Confidence regarding procedural issues related to ethics was significantly higher for the EI group than for the controls. Responses to a simulated case showed that significantly fewer house officers in the EI group would intubate a patient for whom such therapy would be futile. We conclude that ethics education can have an impact on house officers' confidence and their responses to a simulated case, and that the EI was more effective than the LI. Such results have implications regarding the implementation of ethics education during residency. (shrink)

It is believed that the atmosphere in which employees carry out their responsibilities influences whether employees will behave ethically. An important factor contributing to the integrity of the financial reporting process is the tone set by senior management (i.e., the corporate environment). This study was conducted to describe financial accountants'' perceptions of management''s ethical standards. These perceptions are based on both management''s actions and management''s expectations of the employee. This researcher also attempted to identify demographic variables that are related to (...) these perceptions. The results are based on a survey mailed to 400 CPAs who prepare financial reports. Accountants generally perceive management''s conduct as ethical and believe that management expects them to behave ethically. Of particular interest is that respondents have more positive attitudes about management''s expectations of them than they do about management''s own actions in terms of ethical behavior. The majority of respondents reported at least some pressure to achieve short-term performance targets. Management level, industry, size of an organization, and gender were all found to be related to employee perceptions. (shrink)

Disjunctivism about sensory experience is frequently put forward in defence of a particular conception of perception and perceptual experience known as naïve realism. In this paper, I present an argument against naïve realism that proceeds through a rejection of disjunctivism. If the naïve realist must also be a disjunctivist about the phenomenal nature of experience, then naïve realism should be abandoned.

To avoid misinterpretations one should substitute the ambiguous notion of 'new disease' with 'emerging disease'. A disease can be classified emergent in at least five dif férent historical situations; 1) it existed before it could be first identified but was overlooked from a médical point of view because it could not be conceptualized as a nosological entity; 2) it existed but was not noticed until a quantitative and/or qualitative change in its mani festations; 3) it did not exist in a (...) particular région of the world before its introduction from other régions; 4) it never existed in a human population but only in an animal population; 5) it is completely new - the triggering germ and/or necessary environmental conditions did not exist prior to the first clinical manifestations. A sériés of historical examples illustrate this classification. (shrink)

The imbalance between supply of organs for transplantation and demand for them is widening. Although the current international drive to re-establish procurement via non-heart beating organ donation/donor is founded therefore on necessity, the process may constitute a desirable outcome for patient and family when progression to brain stem death does not occur and conventional organ retrieval from the beating heart donor is thereby prevented. The literature accounts of this practice, however, raise concerns that risk jeopardising professional and public confidence in (...) the broader transplant programme. This article focuses on these clinical, ethical, and legal issues in the context of other approaches aimed at increasing donor numbers. The feasibility of introducing such an initiative will hinge on the ability to reassure patients, families, attendant staff, professional bodies, the wider public, law enforcement agencies, and the media that practitioners are working within explicit guidelines which are both ethically and legally defensible.

Discusses the metaphysics of the iterative conception of set.

The editorial in the September 1982 issue of this journal and many articles before and since have addressed the problem of informed consent. Is it possible? Is it a useful concept? Is there anything new to be said about it? In this article the basic rationale of the rule (patient autonomy) is explained and the extent of the rule explored. Various exceptions have been offered by the law and an attempt is made to catalogue the chief of these. A number (...) of specially vulnerable groups are then identified, the most important, and vexed, being children. How can informed consent be secured in the case of young patients? Finally, a few problems are mentioned in an attempt to get this subject back to reality. The appeal to the principle primum non nocere may be medical paternalism in disguise. Informed consent is the competing principle that reminds us of the primacy of human autonomy. A pointer is given to the future: even the use of sound recordings to explain medical procedures and to activate informed consent so that it may become a reality and not just a lawyer's myth, should be considered.
