Social learning has been shown to be an evolutionarily adaptive strategy, but it can be implemented via many different cognitive mechanisms. The adaptive advantage of social learning depends crucially on the ability of each learner to obtain relevant and accurate information from informants. The source of informants’ knowledge is a particularly important cue for evaluating advice from multiple informants; if the informants share the source of their information or have obtained their information from each other, then their testimony is statistically (...) dependent and may be less reliable than testimony from informants who do not share information. In this study, we use a Bayesian model to determine how rational learners should incorporate the effects of shared information when learning from other people, conducting three experiments that examine whether human learners behave similarly. We find that people are sensitive to a number of different patterns of dependency, supporting the use of a sophisticated strategy for social learning that goes beyond copying the majority, and broadening the situations in which social learning is likely to be an adaptive strategy.

Several authors have recently begun to apply virtue theory to argumentation. Critics of this programme have suggested that no such theory can avoid committing an ad hominem fallacy. This criticism is shown to trade unsuccessfully on an ambiguity in the definition of ad hominem. The ambiguity is resolved and a virtue-theoretic account of ad hominem reasoning is defended.

Ubiquitous healthcare is an emerging area of technology that uses a large number of environmental and patient sensors and actuators to monitor and improve patients' physical and mental condition. Tiny sensors gather data on almost any physiological characteristic that can be used to diagnose health problems. This technology faces some challenging ethical questions, ranging from the small-scale individual issues of trust and efficacy to the societal issues of health and longevity gaps related to economic status. It presents particular problems in (...) combining developing computer/information/media ethics with established medical ethics. This article describes a practice-based ethics approach, considering in particular the areas of privacy, agency, equity and liability. It raises questions that ubiquitous healthcare will force practitioners to face as they develop ubiquitous healthcare systems. Medicine is a controlled profession whose practise is commonly restricted by government-appointed authorities, whereas computer software and hardware development is notoriously lacking in such regimes.

Purpose This paper aims to present the baseline English survey used in the other papers in this special issue. Design/methodology/approach The survey includes yes/no, Likert scale and free text responses, which were analysed quantitatively and qualitatively. Findings Respondents to the survey expressed divergent views of whether they would emulate Snowden, even though most in all countries believed he had helped rather than harmed society. Originality/value This is the only such broad survey on attitudes to Snowden of which the authors are (...) aware. (shrink)

Interpretations of the inner word overlook the fact that for Gadamer language is both written and spoken and that these two mediums are in a dialectical relation. After disputing Zimmermann’s interpretation of the inner word, the paper uses McLuhan to explain Gadamer’s dialectical method for understanding how thought that comes to language participates in the self-unfolding structure of a living organism. Central to this argument is a turn of the inner ear which in contrast to sensory memory based on sight (...) recollects the musical origins of language in acoustic space and renders the movements of a dialogue comparable to song.

Ferrari’s critique founders on two issues. Firstly, he does not always represent Toulmin’s view of mathematics and mathematical arguments accurately (indeed, he sometimes attributes to Toulmin positions Toulmin was actually attacking). More importantly, the view of mathematics and mathematical arguments that Toulmin defends in ‘The Uses of Argument’ has no bearing on the value of applying Toulmin’s model to mathematics education. The scholars who proposed this application paid little or no attention to Toulmin’s wider philosophical views and nor should they (...) have done; like many tools, Toulmin’s model found an application its inventor did not anticipate.

Buchanan highlighted the inconsistencies that arise when public services are financed by general taxation. Citizens increase their demand for services, even though citizens are reticent to increase taxation. Buchanan invited readers to explore the impact of different assumptions of politicians’ behaviour. In this chapter, attention focuses on the way that vote maximising governments are likely to respond to the divorce between receipt and payment for services. Buchanan illustrated his analysis with reference to the National Health Service in the UK. Predictions (...) are tested with reference to the pattern of excess demand in the National Health Service between 1970 and 2012. (shrink)

Is it possible to distinguish communities of arguers by tracking the argumentation schemes they employ? There are many ways of relating schemes to communities, but not all are productive. Attention must be paid not only to the admissibility of schemes within a community of argumentational practice, but also to their comparative frequency. Two examples are discussed: informal mathematics, a convenient source of well-documented argumentational practice, and anthropological evidence of nonstandard reasoning.

PurposeAs part of an international study of knowledge of and attitudes to Snowden’s revelations about the activities of the National Security Agency/Government Communications Headquarters, this paper aims to deal with Germany, taking its socio-cultural and political environment surrounding privacy and state surveillance into account.Design/methodology/approachA questionnaire was answered by 76 German University students. The quantitative responses to the survey were statistically analysed as well as qualitative considerations of free text answers.FindingsSnowden’s revelations have had an important influence over German students’ attitudes toward (...) privacy and state surveillance, and show concerns over the privacy risks associated with Internet activity.Practical implicationsThe study results imply a need to build a collective awareness of the importance of the right to privacy and its responsibilities, the available technological options for individuals to exert their own privacy and security and the democratic means to agree and enforce appropriate legal restrictions on state surveillance.Social implicationsYoung Germans support Snowden’s actions and would be more willing to emulate him in Germany than in the USA. While many believe that people must give up some privacy and freedom for security, few seem to believe that current US or German approaches are valid and justified.Originality/valueThis study is the first attempt to investigate the social impact of Snowden’s revelations on German students’ attitudes toward privacy and state surveillance as part of cross-cultural analyses between eight countries.

An integrity system is an integrated assemblage of institutional mechanisms, designed to minimize ethical misconduct and promote ethical health in institutions, organizations, occupations and the like. This book analyzes, describes and demonstrates the value of well-designed integrity systems for efficient, effective and ethically sustainable practice, in occupational groups in particular. Developing a blueprint for the design of integrity systems which can be tailored to the specific ethical needs of different occupational groups, this book furthers the general project of ethically informed (...) institutional design. The approach taken reflects the authors' academic background in professional ethics, as well as their extensive experience in the application of ethical theories and perspectives to the problems and challenges encountered by various occupational groups, such as accountants, business people, lawyers, doctors, nurses, social workers, engineers, emergency service workers and police.

Abstract The institution of war is the broad framework of rules, norms, and organizations dedicated to the prevention, prosecution, and resolution of violent conflict between political entities. Important parts of that institution consist of the accountability arrangements that hold between armed forces, the political leaders who oversee and direct the use of those forces, and the people in whose name the leaders act and from whose ranks the members of the armed forces are drawn. Like other parts of the institution, (...) these arrangements are responsive to changes in military technology and needs, to geopolitical facts, and to moral and political norms. In particular, they are sensitive to the forms that military organization takes. Since the emergence of modern states in Europe some 500 years ago, there have been three main such forms: private providers?in the form of mercenaries, in early modern Europe?then professional standing armies, which in turn developed into citizen armies. Although elements of the three organizations have coexisted in many armies, the citizen army model has dominated until recently. That model brought with it a particular conception of the accountability relations between the army, the state, and the people. The state had authority over and directed the army, which was accountable to it. In turn the state was accountable for its use of the army to the people, on whose behalf it acted. The dominance of state authority over the military is now under strain, with the professional and private elements?in the form of private military and security companies (PMSCs)?having increasing importance. As those elements increase in power and presence, so it becomes more difficult to make the state accountable to the people for its use of the military, and more difficult for the people to act as a restraining force on the way in which the military used. In this essay, I outline and assess these developments?with particular emphasis on the emergence of PMSCs?in the light of a liberal view of (political) violence. The essay focuses on the situation in the United States, which possesses by far the most important military force in the world today, and in which the use of PMSCs is most developed. The paper has three main sections and a brief conclusion: the first section sketches the liberal view of violence and its implications for organizations dedicated to its use; the second outlines the salient characteristics of the three historically dominant forms of armies; and the third looks at the current situation in which the three forms coexist uneasily.

Poststructuralism and the Politics of Method examines the political possibilities emerging with poststructuralist epistemology. Beginning with the premises for the construction of knowledge claims, Koch explores the dimensions of materialism, democracy, power, leftist politics, and other themes emerging from the this twentieth century philosophic movement.

This thesis is a critique of functionalism in the philosophy of mind. I distinguish three tenets, or 'dogmas' of functionalism, viz: Mental states are causes of behaviour; Mental states can, in principle, be defined in non-mental terms; We understand everything, or at least everything of importance, about the mental states of people, by subsuming token mental states under one or other mental state type. ;The first dogma is rejected in the form which identifies mental state types with physical types, on (...) the ground that it commits us to the doubtful possibilities of mental states without any relevant behaviour, and behaviour without a relevant mental state . It is found to be not mandatory in the form which identifies mental state types with functional types, on the ground that the phenomena appealed to in support of the dogma is consistent with a view of mental states which endorses the dogma in at best a trite and philosophically uninteresting sense . The second dogma is rejected on the ground that cannot account for what I call the 'affective animation' of the behaviour of creatures with mental states . I develop a concept I call personal response---the kind of response we have to other human beings as opposed to inanimate nature---and defend principle which says: Commonsense understanding that someone is in a mental state requires proneness to a personal response in relation to that person. ;Certain implications are drawn from for reductionism, for meta-ethics, and for the third dogma . I argue that the third dogma is false on the around that it cannot account for our sense of the individuality of persons, unless that very notion of individuality, which comes from quite outside functionalism, is used to gloss the idea of subsumption under a type.

The unification of microscopic and macroscopic models of brain behaviour is of paramount importance and Wright & Liley's target article provides some important groundwork. In this commentary, I propose that a useful approach for the future is to incorporate a developmental perspective into such models. This may be an important constraint, providing a key to understanding the nature of macroscopic measures of brain function such as functional measures like ERP.

The whole of the premodern Indian world appears shot through with language. The analysis of language, first undertaken to preserve the sacred texts of the Brahmins, achieved such conceptual sophistication that it served as the model, directly or indirectly, for almost all traditions of systematic thought, regardless of religious affiliation. Language was implicated in all the most important philosophical debates, regarding the nature of reality and the foundations of knowledge, and became an object of philosophical debate itself. Given the enormous (...) tangle of sources that address these issues, spanning several traditions of thought, and given their complexity, if not abstruseness, it would be difficult for anyone to...

Leibniz and China: A Commerce of Light. Cambridge-New York: Cambridge University Press, 2004. Pp. xvi + 224. Cloth, $65.00. In his Leibniz and China, Franklin Perkins undertakes two main tasks. The first is historical: to illuminate Leibniz's nearly lifelong interest in China within the context of early modern Europe as well as (...) within Leibniz's own moral, scientific, and religious concerns. The second task is philosophical: to show that Leibniz's interest is not accidental—that his "openness to China is not an accident of his experience or personality but flows naturally from his philosophy" . Specifically, Perkins aims to show that, unlike the philosophies of some of his prominent predecessors and contemporaries (viz.,.. (shrink)
