The early withdrawal of students from healthcare education programmes, particularly nursing, is an international concern and, despite considerable investment, retention rates have remained stagnant. Here, a regional study of healthcare student retention is used as an example to frame the challenge of student attrition using a concept from policy development, wicked problem theory. This approach allows the consideration of student attrition as a complex problem derived from the interactions of many interrelated factors, avoiding the pitfalls of small‐scale interventions and over‐simplistic (...) assumptions of cause and effect. A conceptual framework is proposed to provide an approach to developing actions to reduce recurrent investment in interventions that have previously proved ineffective at large scale. We discuss how improvements could be achieved through integrated stakeholder involvement and acceptance of the wicked nature of attrition as a complex and ongoing problem. (shrink)

Economists have always recognised that human endeavours are constrained by our limited and uncertain knowledge, but only recently has an accepted theory of uncertainty and information evolved. This theory has turned out to have surprisingly practical applications: for example in analysing stock market returns, in evaluating accident prevention measures, and in assessing patent and copyright laws. This book presents these intellectual advances in readable form for the first time. It unifies many important but partial results into a satisfying single picture, (...) making it clear how the economics of uncertainty and information generalises and extends standard economic analysis. Part One of the volume covers the economics of uncertainty: how each person adapts to a given fixed state of knowledge by making an optimal choice among the immediate 'terminal' actions available. These choices in turn determine the overall market equilibrium reflecting the social distribution of risk bearing. In Part Two, covering the economics of information, the state of knowledge is no longer held fixed. Instead, individuals can to a greater or lesser extent overcome their ignorance by 'informational' actions. The text also addresses at appropriate points many specific topics such as insurance, the Capital Asset Pricing model, auctions, deterrence of entry, and research and invention. (shrink)

This article suggests evidence for and reasons why prior acquisition may either facilitate or inhibit acquisition of a new construction. It investigates acquisition of the German passive and future constructions which contain a lexical verb with either the auxiliary sein “to be” or werden “to become”, and are related through these to potential supporting constructions. We predicted that a supported construction should be acquired earlier, faster, and unusually rapidly. An inhibited construction should show an extended depressed usage. We analyzed a (...) dense corpus of a German boy between 2;0 and 5;0. He acquired the sein- before the werden-passive. The former was supported by his prior acquisition of the sein copula, whereas the werden-passive itself supported one werden copula construction. He acquired the werden-future extremely slowly due to the hindrance of a semantically identical construction. These results fit with an emergentist approach in which apparently “sudden” acquisition is still due to gradual learning mechanisms. (shrink)

Software-intensive systems are ubiquitous in the industrialized world. The reliability of software has implications for how we understand scientific knowledge produced using software-intensive systems and for our understanding of the ethical and political status of technology. The reliability of a software system is largely determined by the distribution of errors and by the consequences of those errors in the usage of that system. We select a taxonomy of software error types from the literature on empirically observed software errors and compare (...) that taxonomy to Giuseppe Primiero’s Minds and Machines 24: 249–273, (2014) taxonomy of error in information systems. Because Primiero’s taxonomy is articulated in terms of a coherent, explicit model of computation and is more fine-grained than the empirical taxonomy we select, we might expect Primiero’s taxonomy to provide insights into how to reduce the frequency of software error better than the empirical taxonomy. Whether using one software error taxonomy can help to reduce the frequency of software errors better than another taxonomy is ultimately an empirical question. (shrink)

The growing demand for societal impact of teaching, research, and operations necessitates fresh approaches to our analysis of business school rankings. I discuss the Financial Times’ approach and the need for fresh methods, metrics, and standards.

Operational definitions of biological altruism in terms of actual fitness exchanges will not work because they include accidental acts as altruistic and exclude altruistic acts that have gone awry. I argue that the definition of biological altruism should contain an analogue of the role intention plays in psychological altruism. I consider two possibilities for this analogue, selected effect functions and the proximate causes and effects of behavior. I argue that the selected-effect function account will not work because it confuses the (...) explanation of some altruistic behavior with the definition of all of it and the information needed to justify a selected effect account of function is too often inaccessible. Close attention to the proximate explanations of a behavior is all that is needed to determine if an act is biologically altruistic, returning biological altruism to descriptive ethology, where it belongs.

Auditory scene analysis is an elementary aspect of music perception, yet only little research has scrutinized auditory scene analysis under realistic musical conditions with diverse samples of listeners. This study probed the ability of younger normal-hearing listeners and older hearing-aid users in tracking individual musical voices or lines in JS Bach's The Art of the Fugue. Five-second excerpts with homogeneous or heterogenous instrumentation of 2–4 musical voices were presented from spatially separated loudspeakers and preceded by a short cue for signaling (...) the target voice. Listeners tracked the cued voice and detected whether an amplitude modulation was imposed on the cued voice or a distractor voice. Results indicated superior performance of young normal-hearing listeners compared to older hearing-aid users. Performance was generally better in conditions with fewer voices. For young normal-hearing listeners, there was interaction between the number of voices and the instrumentation: performance degraded less drastically with an increase in the number of voices for timbrally heterogeneous mixtures compared to homogeneous mixtures. Older hearing-aid users generally showed smaller effects of the number of voices and instrumentation, but no interaction between the two factors. Moreover, tracking performance of older hearing aid users did not differ when these participants did or did not wear hearing aids. These results shed light on the role of timbral differentiation in musical scene analysis and suggest reduced musical scene analysis abilities of older hearing-impaired listeners in a realistic musical scenario.

This article proposes a new approach to employing Maurice Merleau-Ponty's philosophy in the philosophy of religion. Rather than finding a latent theology in Merleau-Ponty – as some interpreters do – this article argues that Merleau-Ponty's later ontology can provide the basis for a philosophical anthropology which can help us understand why human beings are drawn to religion and how this is expressed in affective and ritual practice. This ontology can help us to understand the notion of freedom as it applies (...) to affective, embodied, and ritual religious practices and begins to sketch out how freedom might be understood in light of embodiment.

ABSTRACT Philosophy of religion has recently made a turn to lived religion, an approach which seeks to understand lived religion as it is experienced concretely by individual practitioners. However, this turn to lived religion has seen limited engagement with the notion of belonging. Belonging here refers to the felt sense of being part of a group – of insidership – along with the development of positive social ties and mutual affective concern. It is my contention in this paper that reflection (...) on this experience of belonging can improve our understanding of lived religion. In particular, I argue that human beings have an affective need to belong – a fundamental and affective need for belonging and positive social relationship which is felt in the body and rooted in human biology and evolutionary history. This paper makes the case for the affective need to belong, before examining its implications for understanding religion. It finds that the affectivity of belonging is capable of raising the affective salience of certain in-group beliefs, as well as creating affective hurdles to dissent, and in so doing can help to explain processes of religion conversion, sustained religious adherence, and religious disaffiliation.

This book begins to recognize and represent the impact of Black feminist and womanist theory in curriculum theorizing. This collection includes a vibrant group of women of color who do curriculum work to reflect on a Black feminist/womanist scholar, text, and/or concept and how it has influenced and enriched their work as scholar-activists.

Providing sport psychology services to athletes and coaches before and during the Olympic Games presents a number of ethical concerns and challenges for the practitioner. These challenges are amplified by the nontraditional way in which sport psychology services are delivered, requiring careful attention to maintaining ethical behavior no matter the setting. The purpose of this article is, from the perspective of sport psychology consultants employed by the U.S. Olympic Committee, to outline specific challenges, including prolonged travel with teams, multiple relationships, (...) and such Olympic Games-related issues as dealing with the media, team identification, servicing multiple teams simultaneously, and practitioner self-care. Strategies for coping with these challenges, as well as questions to ponder, are also presented as a way to increase awareness of this field's unique challenges for the aspiring practitioner.

We propose the SIMS model can be strengthened by detailing the dynamic interaction between sensorimotor activation and contextual conceptual information. Rapidly activated evaluations and contextual knowledge can guide and constrain embodied simulations. In addition, we stress the potential importance of extending the SIMS model to dynamic social interactions that go beyond the passive observer.

The central tradition of mainline economics deals with one way of making a living; producing goods and services. But there is another way of getting ahead through conflict or the 'dark side', by appropriating what others have produced. Parallel to military aggression and resistance, the dark side includes non-military activities such as litigation, strikes and lockouts, takeover contests, and bureaucratic back-biting struggles. This volume brings the analysis of conflict into the mainstream of economics. Part I explores the causes, conduct, and (...) consequences of conflict as an economic activity. Part II delves deeply into the evolutionary sources of our capacities, physical and mental, for both conflict and cooperation. The introductory chapter of the volume, which outlines the significance of the dark side, was the author's 1993 Presidential Address to the Western Economic Association. Other chapters investigate economic models, historical discussions, experimental tests, and applications to topics in political science and law. (shrink)

“Metaphysical questions relating to what ex­ists do not seem to fade away” notes Jack Kaminsky in this book, which takes as its starting point the Quinian view that we de­termine what exists by means of the formal systems we construct to explain the world. This starting point, Kaminsky points out, is not novel; philosophers have often tried to construct formal systems, and from these systems they have been able to deduce what can be said to exist. Contemporary formal systems (...) are different from earlier ones, how­ever, because they make more extensive use of the results of linguistics, logic, and mathe­matics studies. But these contemporary formal systems also must state eventually what their commitments to existence are, and they must be able to show their commit­ments to be free of paradox, ambiguity, and contradiction. Given these conditions, Kaminsky exam­ines the difficulties inherent in the existence claims of contemporary formal language systems. To do this he uses only a minimum of the technical elements of propositional and first-order quantificational logic. He concludes: many existential commitments are relative to the formal systems of time; some commitments seem to be absolute; and some problems—those relating to vacuous terms—arise only because no distinction is made between humanly constructed objects and naturally constructed objects.

Professor S. F. Barker has recently argued that the theory of the status of theoretical concepts in natural science put forward by Hempel and Braithwaite is mistaken. Essentially this "formalistic" theory says that these concepts "take on" meaning from their place in a total theoretical system which as a whole implies testable observation statements. In the paper it is argued that Barker's criticism of the Hempel-Braithwaite theory is mistaken because (a) he does not sufficiently consider the operative empirical restrictions on (...) concept formation in scientific theorizing, and (b) his criticisms are based on an acceptance of a narrow empiricism which would reject most existing theoretical natural science as empirically meaningless.

Mark Blaug and I agree that if there is a realist interpretation of economic behavior to be discerned in Friedman, it is to be found not in Friedman's belief that the profit motive overrides other possible motives, but in his belief that a selection mechanism is working in competitive markets. Our joint sympathy for evolutionary economics is largely based on a conviction that the conception of competition as a dynamic evolutionary process is rather plausible. We disagree, however, on two issues: (...) first, how important the evolutionary conception was for Friedman's overall argument; and, second, whether we can learn something about the real world from rigorous formal analytical models. In this article, I explain and argue for my position on these two issues, and use Nelson and Winter's theory of evolutionary economics to support an illustrate my argument. (shrink)

ABSTRACT A brief reflection on the possibility of contingency in the midst of what cannot be said.

From providing on-demand access to vast catalogues of recorded music at little or no cost to the use of Big Data to personalise the experience of consuming music, music streaming platforms, such as Spotify and Apple Music, have the potential to disrupt the part that music taste plays in the performance of class identities and the reproduction of class privilege in ways not previously encountered. The influential sociologist, Pierre Bourdieu, demonstrated that cultural taste – what and how people consume cultural (...) goods, such as music, food and fashion – is shaped by class background and in doing so serves to mark and reproduce class differences in everyday life. In this commentary, I consider how sociologists might address the important but challenging question of if and how are music streaming platforms shaping the part that music taste plays in the performance of class identities and the cultural reproduction of class privilege. I discuss some ways in which music streaming platforms may be shaping how class identities are performed through how people consume music, drawing attention to consumption practices that have the potential to both involve and resist the use of music streaming platforms in the pursuit of social distinction.
