Models of recognition memory have traditionally struggled with the puzzle of criterion setting, a problem that is particularly acute in cases in which items for study and test are of widely varying types, with differing degrees of baseline familiarity and experience (e.g., words vs. random dot patterns). We present a dynamic model of the recognition process that addresses the criterion setting problem and produces joint predictions for choice and reaction time. In this model, recognition decisions are based not on the (...) absolute value of familiarity, but on how familiarity changes over time as features are sampled from the test item. Decisions are the outcome of a race between two parallel accumulators: one that accumulates positive changes in familiarity (leading to an ‘‘old’’ decision) and another that accumulates negative changes (leading to a ‘‘new’’ decision). Simulations with this model make realistic predictions for recognition performance and latency regardless of the baseline familiarity of study and test items. (shrink)

O texto busca refletir criticamente sobre alguns fenômenos sociais contemporâneos, fortemente imbricados, notadamente as tendências contemporâneas de entrincheiramento e achatamento do eu; o reforço da iconomania e da compulsiva produção de avatares de si, em meio a bolhas narcísicas digitais, franqueadas pelas recentes tecnologias de informação e comunicação; e a virtual destruição da intimidade e da privacidade, diante da emergência de panópticos digitais e da vigilância algorítmica. Para tanto, toma-se como ponto de partida proposições apresentadas por Christopher Lasch em sua (...) obra _The Minimal Self: Psychic Survival in Troubled Times_, publicada originalmente em 1984, em particular a própria noção de mínimo eu, as quais são, então, entretecidas com argumentos de Christophe Dejours, Günther Anders, Theodor Adorno, Hebert Marcuse, Jonathan Crary, entre outros. Em acréscimo, busca-se salientar a ancoragem desses processos à hodierna dinâmica de acumulação de capital, a partir da crítica da economia política, perspectiva que atravessa todo o texto, bem como assinalar a atualidade do pensamento de Lasch.

This 1990 collection explores one recurrent theme connecting philosophy and politics: the relation between the nature of man and the structure of society. It does so by concentrating on the topical issue of the market economy as an attempt to resolve the clash between individual autonomy and collective action. Beginning with a historical and personal recollection by Enoch Powell and a response by Robert Skidelsky, the volume then provides a forum for political theorists and philosophers to take issue on the (...) fundamental topics of markets and morals; liberal man; and equality and libertarianism. It succeeds equally as a stimulating textbook and a book for the general reader who wishes to understand the philosophical issues arising in a market economy. (shrink)

“Free riding,” used as a descriptive term, refers to taking a jointly produced benefit without contributing towards its production. Used as a term of criticism, it refers to the wrongful failure to contribute towards the joint production of benefits that one receives. On either usage, the central interest of moral philosophy in free riding is the same: to specify the conditions under which not contributing towards the joint production of benefits that one receives is wrong, and to explain why.

In this paper we consider an intuitionistic variant of the modal logic S4 (which we call IS4). The novelty of this paper is that we place particular importance on the natural deduction formulation of IS4— our formulation has several important metatheoretic properties. In addition, we study models of IS4— not in the framework of Kirpke semantics, but in the more general framework of category theory. This allows not only a more abstract definition of a whole class of models but also (...) a means of modelling proofs as well as provability. (shrink)

Aristotle argued that you need some wealth to live well. The Stoics argued that you could live well with or without wealth. But the Cynics argued that wealth is a hinderance. For the Cynics, a good life consists in self-sufficiency, or being able to rule and help yourself. You accomplish this by living simply and naturally, and by subjecting yourself to rigorous philosophical exercises. Cynics confronted people to get them to abandon extraneous possessions and positions of power to live better. (...) And while the Cynics were experts in living in this way, their ascetic lifestyles made their message curious to some audiences. This paper reflects on Cynic ascetic practices and the ways others perceived them. (shrink)

A significant proportion of conservationists' work is directed towards efforts to save disappearing species. This relies upon the belief that species extinction is undesirable. When justifications are offered for this belief, they very often rest upon the assumption that extinction brought about by humans is different in kind from other forms of extinction. This paper examines this assumption and reveals that there is indeed good reason to suppose current anthropogenic extinctions to be different in kind from extinctions brought about at (...) other times or by other factors. Having considered – and rejected – quantity and rate of extinction as useful distinguishing factors, four alternative arguments are offered, each identifying a way in which anthropogenic extinction is significantly different from other forms of extinction, even mass extinction: (1) Humans are a different kind of natural cause from other causes of extinction; (2) Extinctions brought about by humans are uniquely persistent; (3) Anthropogenic extinctions are effectively random whereas past mass extinctions are rule-bound; (4) The impact of the current anthropogenic extinction event differs from the impact of other extinction events of the past, such that future recovery may not follow past patterns. Together, these four arguments suggest that the present-day extinction event brought about by humans may be unprecedented and that we cannot clearly extrapolate from past to present recovery from extinctions. Although insufficient as justification for the claim that present-day extinctions are undesirable, the arguments provide some ammunition for conservationists' conviction that species extinction – in which humans play an accelerating role – ought to be prevented.

Knowledge of the ethical and legal basis of medicine is as essential to clinical practice as an understanding of basic medical sciences. In the UK, the General Medical Council requires that medical graduates behave according to ethical and legal principles and must know about and comply with the GMC’s ethical guidance and standards. We suggest that these standards can only be achieved when the teaching and learning of medical ethics, law and professionalism are fundamental to, and thoroughly integrated both vertically (...) and horizontally throughout, the curricula of all medical schools as a shared obligation of all teachers. The GMC also requires that each medical school provides adequate teaching time and resources to achieve the above. We reiterate that the adequate provision and coordination of teaching and learning of ethics and law requires at least one full-time senior academic in ethics and law with relevant professional and academic expertise. In this paper we set out an updated indicative core content of learning for medical ethics and law in UK medical schools and describe its origins and the consultative process by which it was achieved.

The classical Athenian philosopher Socrates was tried in 399 BCE on the basis of two notoriously ambiguous charges: corrupting the youth and impiety (in Greek, asebeia). A majority of the 501 dikasts (Athenian citizen-jurors) voted to convict him. Socrates was ultimately sentenced to death by drinking a hemlock-based liquid. This well-known account of the trial is by Plato, one of Socrates' students and a famous philosopher in his own right. Whether Socrates was punished unjustly is a contested issue which to (...) this day inspires discussions about the nature and meaning of justice. (shrink)

It is a fundamental cornerstone of thermodynamics that entropy (SU,V\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$S_{U,V}$$\end{document}) increases in spontaneous processes in isolated systems (often called closed or thermally closed systems when the transfer of energy as work is considered to be negligible) and achieves a maximum when the system reaches equilibrium. But with a different sign convention entropy could just as well be said to decrease to a minimum in spontaneous constant U, V processes. It would then (...) change in the same direction as the thermodynamic potentials in spontaneous processes. This article discusses but does not advocate such a change. (shrink)

Next SectionFollowing the influential Gifford and Reith lectures by Onora O’Neill, this paper explores further the paradigm of individual autonomy which has been so dominant in bioethics until recently and concurs that it is an aberrant application and that conceptions of individual autonomy cannot provide a sufficient and convincing starting point for ethics within medical practice. We suggest that revision of the operational definition of patient autonomy is required for the twenty first century. We follow O’Neill in recommending a principled (...) version of patient autonomy, which for us involves the provision of sufficient and understandable information and space for patients, who have the capacity to make a settled choice about medical interventions on themselves, to do so responsibly in a manner considerate to others. We test it against the patient–doctor relationship in which each fully respects the autonomy of the other based on an unspoken covenant and bilateral trust between the doctor and patient. Indeed we consider that the dominance of the individual autonomy paradigm harmed that relationship. Although it seems to eliminate any residue of medical paternalism we suggest that it has tended to replace it with an equally (or possibly even more) unacceptable bioethical paternalism. In addition it may, for example, lead some doctors to consider mistakenly that unthinking acquiescence to a requested intervention against their clinical judgement is honouring “patient autonomy” when it is, in fact, abrogation of their duty as doctors.

In _Violence and Civility_, Étienne Balibar boldly confronts the insidious causes of violence, racism, nationalism, and ethnic cleansing worldwide, as well as mass poverty and dispossession. Through a novel synthesis of theory and empirical studies of contemporary violence, the acclaimed thinker pushes past the limits of political philosophy to reconceive war, revolution, sovereignty, and class. Through the pathbreaking thought of Derrida, Balibar builds a topography of cruelty converted into extremism by ideology, juxtaposing its subjective forms and its objective manifestations. Engaging (...) with Marx, Hegel, Hobbes, Clausewitz, Schmitt, and Luxemburg, Balibar introduces a new, productive understanding of politics as antiviolence and a fresh approach to achieving and sustaining civility. Rooted in the principles of transformation and empowerment, this theory brings hope to a world increasingly divided even as it draws closer together. (shrink)
