"This collection of chapters illustrates how Posner's examination of elementary processes has moved the field toward a fundamental level of understanding about human cognition. This basic understanding will greatly affect how we deal with cognitive development problems that derive either from deficiency of experience or from genetic differences."--Jacket.

The purpose of this paper is to provide a holistic examination of local food entrepreneurs (LFE) across the local food system (LFS) of a specific U.S. geographic region, including the drivers and barriers to their success. Over the past few decades, there has been a surge in entrepreneurs becoming involved in the LFS which includes the production (farming and manufacturing), distribution, and retail of local ag-related products and services. The LFS is complex and entrepreneurs operating within the system are often (...) met with steep barriers of entry and have trouble maintaining long-term success. Through recorded semi-structured interviews of LFEs (producers, processors, and purveyors) in the Missouri Ozark region, data was gathered and coded according to grounded theory methodologies. From the data collection, 24 emergent themes were identified using thematic clustering. These were further consolidated into eight categorical themes (strategy, skills development, financially sustainable model, differentiation drivers, operational drivers, external drivers, internal constraints, and external constraints) and three over-riding themes (approach, drivers, and barriers). This cross-sectional approach in examining entrepreneurs across the value chain in an LFS provides new insights into the unique entrepreneurial mindset of LFEs. (shrink)

Oaksford & Chater (O&C) focus on patterns of typical adult reasoning from a probabilistic perspective. We discuss implications of extending the probabilistic approach to lifespan development, considering the role of working memory, strategy use, and expertise. Explaining variations in human reasoning poses a challenge to Bayesian rational analysis, as it requires integrating knowledge about cognitive processes.

Although the mapping between form and meaning is often regarded as arbitrary, there are in fact well-known constraints on words which are the result of functional pressures associated with language use and its acquisition. In particular, languages have been shown to encode meaning distinctions in their sound properties, which may be important for language learning. Here, we investigate the relationship between semantic distance and phonological distance in the large-scale structure of the lexicon. We show evidence in 100 languages from a (...) diverse array of language families that more semantically similar word pairs are also more phonologically similar. This suggests that there is an important statistical trend for lexicons to have semantically similar words be phonologically similar as well, possibly for functional reasons associated with language learning.

Zipf famously stated that, if natural language lexicons are structured for efficient communication, the words that are used the most frequently should require the least effort. This observation explains the famous finding that the most frequent words in a language tend to be short. A related prediction is that, even within words of the same length, the most frequent word forms should be the ones that are easiest to produce and understand. Using orthographics as a proxy for phonetics, we test (...) this hypothesis using corpora of 96 languages from Wikipedia. We find that, across a variety of languages and language families and controlling for length, the most frequent forms in a language tend to be more orthographically well‐formed and have more orthographic neighbors than less frequent forms. We interpret this result as evidence that lexicons are structured by language usage pressures to facilitate efficient communication. (shrink)

An important part of our Theory of Mind—the ability to reason about other people's unobservable mental states—is the ability to attribute false beliefs to others. We investigated whether processing these false beliefs, as well as similar but nonmental representations, is reliant on language. Participants watched videos in which a protagonist hides a gift and either takes a photo of it or writes a text about its location before a second person inadvertently moves the present to a different location, thereby rendering (...) the belief and either the photo or text false. At the same time, participants performed either a concurrent verbal interference task (rehearsing strings of digits) or a visual interference task (remembering a visual pattern). Results showed that performance on false belief trials did not decline under verbal interference relative to visual interference. We interpret these findings as further support for the view that language does not form an essential part of the process of reasoning online (“in the moment”) about false beliefs. (shrink)

Absolute linguistic universals are often justified by cross-linguistic analysis: If all observed languages exhibit a property, the property is taken to be a likely universal, perhaps specified in the cognitive or linguistic systems of language learners and users. In many cases, these patterns are then taken to motivate linguistic theory. Here, we show that cross-linguistic analysis will very rarely be able to statistically justify absolute, inviolable patterns in language. We formalize two statistical methods—frequentist and Bayesian—and show that in both it (...) is possible to find strict linguistic universals, but that the numbers of independent languages necessary to do so is generally unachievable. This suggests that methods other than typological statistics are necessary to establish absolute properties of human language, and thus that many of the purported universals in linguistics have not received sufficient empirical justification.

Is it true that an ethics of care offers something distinct from other approaches to ethical problems in nursing, especially principlism? In this article an attempt is made to clarify an ethics of care and then to argue that there need be no substantial difference between principlism and an ethics of care when the latter is considered in the context of nursing. The article begins by considering the question of how one could in fact differentiate moral theories. As is explained, (...) this cannot be done merely in light of the moral judgements they defend, nor their ontological commitments (e.g. their view of the nature of persons). Following these methodological beginnings, care-based ethics is described and critically discussed. It is shown that ontological commitments embraced within care ethics do not themselves show that care ethics is distinct from other approaches. The idea of ‘psychological care’ is also discussed, which stems from the work of Margaret Little. Her claim that the ‘gestalts’ of justice and care cannot be combined is rejected in favour of an approach that does just that and which has been developed by Joan Tronto. It is then claimed that the moral commitments of principlism are certainly not incompatible with those of an ethics of care in the nursing context. A challenge to the idea that principlism and ethics of care might be compatible is anticipated in the work of Eva Feder Kittay. This challenge is responded to and it is concluded that care considered as a moral orientation and the moral values embedded in principlism are best combined in the nursing context. Care provides a moral orientation over which the obligations referred to in principlism can be laid. (shrink)

The ethics of care still appeals to many in spite of penetrating criticisms of it which have been presented over the past 15 years or so. This paper tries to offer an explanation for this, and then to critically engage with three versions of an ethics of care. The explanation consists firstly in the close affinities between nursing and care. The three versions identified below are by Gilligan (1982 ), a second by Tronto (1993 ), and a third by Gastmans (...) (2006 ), see also Little (1998 ). Each version is described and then subjected to criticism. It is concluded that where the ethics of care is presented in a distinctive way, it is at its least plausible; where it is stated in more plausible forms, it is not sufficiently distinct from nor superior to at least one other common approach to nursing ethics, namely the much-maligned 'four principles' approach. What is added by this paper to what is already known: as the article tries to explain, in spite of its being subjected to sustained criticism the ethics of care retains its appeal to many scholars. The paper tries to explain why, partly by distinguishing three different versions of an ethics of care. It is also shown that all three versions are beset with problems the least serious of which is distinctiveness from other approaches to moral problems in health care. (shrink)

This paper has three main aims. The first is to provide a critical assessment of two rival concepts of suffering, that proposed by Cassell and that proposed in this journal by van Hooft. The second aim of the paper is to sketch a more plausible concept of suffering, one which derives from a Wittgensteinian view of linguistic meaning. This more plausible concept is labeled an ‘intuitive concept’. The third aim is to assess the prospects for scientific understanding of suffering.

The issues may change with the passing of the years, but the categories of concern change very little: sexuality and the sexes; medical decision-making; justice for the poor, the powerless, the underclass; reproductive decision-making; moral decision-making in business; and personal moral choices. Stevens attempts to present alternative positions on hotly debated new moral issues from a different standpoint, using an ethical pluralism approach. In doing this, he hopes to help readers arrive at their own non-polarized positions by learning from (...) and respecting all parties in the discussion. (shrink)

This paper is prompted by the charge that the prevailing Western paradigm of medical knowledge is essentially Cartesian. Hence, illness, disease, disability, etc. are said to be conceived of in Cartesian terms. The paper attempts to make use of the critique of Cartesianism in medicine developed by certain commentators, notably Leder (1992), in order to expose Cartesian commitments in conceptions of disability. The paper also attempts to sketch an alternative conception of disability — one partly inspired by the work of (...) Merleau-Ponty. In particular, three key Cartesian claims are identified and subjected to criticism. These are as follows: (a) The claim that the body is an object, (b) what is termed here ‘the modularity thesis’, and (c) the claim that the body cannot be constitutive of the self (i.e. since the soul/mind/brain is). In opposition to these claims, it is argued that the body is properly viewed as a subject; that there are neither purely mental, nor purely physical disabilities; and that selves are constituted, at least in part, by their bodies.

It was reported in 2006 that a regime of ‘supervised self harm’ had been implemented at St George’s Hospital, Stafford. This involves patients with a history of self-harming behaviour being offered both emotional and practical support to enable them to do so. This support can extend to the provision of knives or razors to enable them to self-harm while they are being supervised by a nurse. This article discusses, and evaluates from an ethical perspective, three competing responses to self-harming behaviours: (...) to prevent it; to allow it; and to make provision for supervised self-harm. It is argued that of these three options the prevention strategy is the least plausible. A tentative conclusion is offered in support of supervised self-harm. (shrink)

Sports Medicine as an apparent sub-class of medicine has developed apace over the past 30 years. Its recent trajectory has been evidenced by the emergence of specialist international research journals, standard texts, annual conferences, academic appointments and postgraduate courses. Although this field of enquiry and practice lays claim to the title ‘sports medicine’ this paper queries the legitimacy of that claim. Depending upon how ‘sports medicine’ and ‘medicine’ are defined, a plausible-sounding case can be made to show that sports medicine (...) is not in fact a branch of medicine. Rather, it is sometimes closer to practices such as non-therapeutic cosmetic surgery. The argument of the paper is as follows. It begins with a brief statement concerning methodology. We then identify and subscribe to a plausible defining goal of medicine taken from a recognised authority in the field. Then two representative, authoritative, definitions of sports medicine are discussed. It is then shown that acceptance of these definitions of sports medicine generates a problem in that if they are accepted, no necessary commitment to the defining goal of medicine is present within sports medicine. It seems to follow that sports medicine is not medicine. In the final part of the paper a critical response to that conclusion is presented and rebutted. The response is one which rejects the identification of the defining goal of medicine upon which our argument rests. (shrink)

This paper is an attempt to provide a critical evaluation of the theory of disability put forward by Lennart Nordenfelt. The paper is in five sections. The first sets out the main elements of Nordenfelt's theory. The second section elaborates the theory further, identifies a tension in the theory, and three kinds of problems for it. The tension derives from Nordenfelt's attempt to respect two important but conflicting constraints on a theory of health. The problems derive from characterisation of the (...) goals of persons; the difficulty which Nordenfelt has in respecting the plausible view that there is a distinction between illness and disability; and the presence in the theory of other strongly counter-intuitive implications. In section three a defence of Nordenfelt is attempted from within the resources available within his own theory. This defence seeks to exploit his distinctions between a person who is ill and one who is generally disabled and that between first- and second-order disabilities. However, it is concluded that there are insufficient resources within Nordenfelt's theory to fend off the criticisms developed in section two. The fourth section of the paper attempts a defence of Nordenfelt. It is claimed that introduction of the concept of capacity helps to explain differences between problem cases in the theory. Finally, it is shown that at least two important constraints on any theory of disability emerge from the preceding discussion. (shrink)

This article sets out to explore the essential meaning of the experience of exercise through obtaining descriptions of the experience of exercise in relation to various questions about the nature of this experience. The paper proceeds to discuss contemporary research related to aspects of the exercise experience and uses poetry as a vehicle to sensitize readers to the subtleties of the experiences associated with exercise. Using a qualitative methodology, forty three culturally-diverse postgraduate students were given a questionnaire that examined their (...) communal and personal experiences of exercise. Participants were divided into five focus groups, each participating in discussions regarding exercise and its effects. The research outcomes indicate that exercise was generally viewed positively by individuals, and that exercise was felt to be a shared communal experience that fostered cooperation and interaction. The paper concludes by discussing how exercise facilitates an appreciation of the world, and reminds readers that exercise is more than just physical activity, and importantly is a "celebration of the human spirit".

The appropriateness of economic valuations of the natural environment is defended on the basis of an objective analysis of individuals’ preferences. The egoistic model of “economic man” substantiates economic valuations of instrumental values even when markets do not exist and when consumption and use are not involved. However, “altruistic man’s” genuine commitment to the well-being of others, particularly wildlife and future generations, challenges economic valuations at a fundamental level. In this case, self-interest and an indifference between states of the world (...) are secondary and undefined respectively, since preferences are not based on tradeoffs between the welfare of others and self. The appropriateness of economic valuations rests solely with the empirical validity of the assumptions that give rise to economic man. (shrink)

This paper recounts the events surrounding the case of Ashley X, a severely disabled young girl whose parents opted for oestrogen therapy, a hysterectomy and breast removal – the so-called ‘Ashley treatment’ – in order to reduce her projected adult weight and improve her quality of life. Following a description of the events leading up to the procedure itself, and the worldwide debate which ensued, the main arguments in favour and against the procedures are presented. The paper also critically engages (...) with a recent defence of the treatments presented by one of those closely involved with the case – Dr D Diekema. Finally, the recommendations of a report which criticizes procedures at the hospital in which the treatments took place are described, and it is argued that the main recommendation regarding the constitution of the Hospital Ethics Committee (HEC) is ill-thought through and is unlikely to have made any difference to the decision taken by the HEC to approve the Ashley treatments.

Stimulants have been shown to be safe and effective for reduction of the symptoms of attention deficit hyperactivity disorder. Despite much debate, however, there has been little empirical evidence as to whether stimulants affect authenticity and moral agency in children. Singh presents evidence that stimulants do not undercut children's' sense of self and increase their experience of agency. These findings are consistent with laboratory evidence that stimulant drugs in therapeutic doses improve cognitive control over thought and behavior.

In the UK and elsewhere suicide presents a major cause of death. In 2008 in the UK the topic of suicide rarely left the news. Controversy surrounding Daniel James and Debbie Purdy ensured that the problem of assisted suicide received frequent media discussion. This was fuelled also by reports of a higher than usual number of suicides by young people in South Wales. Attention attracted by cases such as that of Daniel James and Debbie Purdy can lead to a neglect (...) of the problem of how to respond to the vast majority of suicides, in which there is no obvious accompanying health problem. This paper seeks to redress that balance to some degree. Its focus is primarily on the provision of assisted suicide when the person seeking such assistance has no accompanying health problem. It is argued that a network of suicide centres (SCs) should be established, the purpose which in certain circumstances, will extend to assisting suicide in cases where a competent person has a definite, sustained intention to end their own life. Arguments in support of this proposal are provided, focusing on respect for autonomy, relief of suffering and respect for the ‘life-plan’ of a person. Considerations relating to reduction of harms to third parties are also recruited. Eight responses to the proposal are considered. But none is found compelling, nor are they found jointly compelling.
