Recent reports published by the United Nations and the World Health Organization suggest that the brain drain of healthcare professionals from the developing to the developed world is decimating the provision of healthcare in poor countries. The migration of these key workers is driven by a combination of economic inequalities and the recruitment policies of governments in the rich world. This article assesses the impact of the healthcare brain drain and argues that wealthy countries have a moral obligation to reduce (...) the flow of healthcare workers from the developing to the developed world.

Neuroscientists are searching for the engram within the conceptual framework established by John Locke's theory of mind. This framework was elaborated before the development of information theory, before the development of information processing machines and the science of computation, before the discovery that molecules carry hereditary information, before the discovery of the codon code and the molecular machinery for editing the messages written in this code and translating it into transcription factors that mark abstract features of organic structure such as (...) anterior and distal. The search for the engram needs to abandon Locke's conceptual framework and work within a framework informed by these developments. The engram is the medium by which information extracted from past experience is transmitted to the computations that inform future behavior. The information-conveying symbols in the engram are rapidly generated in the course of computations, which implies that they are molecules. (shrink)

Hawthorne and Magidor's criticisms of the model of presupposition and assertion that I have used and defended are all based on a rejection of some transparency or introspection of assumptions about speaker presupposition. This response to those criticisms aims first to clarify, and then to defend, the required transparency assumptions. It is argued, first, that if the assumptions are properly understood, some prima facie problems for them do not apply, second, that rejecting the assumptions has intuitively implausible consequences, and third, (...) that the 'margin of error' argument against the principle of positive introspection has a false premiss. The paper concludes with a response to a criticism of what Hawthorne and Magidor call 'the uniformity principle' that is used in the model to explain some pragmatic phenomena. (shrink)

Statisticians in medicine can disagree on appropriate methodology applicable to the design and analysis of clinical trials. So called Bayesians and frequentists both claim ethical superiority. This paper, by defining and then linking together various dichotomies, argues there is a place for both statistical camps. The choice between them depends on the phase of clinical trial, disease prevalence and severity, but supremely on the ethics underlying the particular trial. There is always a tension present between physicians primarily obligated to their (...) own patients (the weight of 'individual ethics') and ethical committees responsible for the scientific merit of the trial and its long-term implications ('collective ethics'). Individual ethics, it is proposed, favour the Bayesian approach; collective ethics, the frequentist. Though in some situations the choice appears clear-cut, there remain other where both methodologies can be appropriate. (shrink)

This article presents seven principles that have guided our thinking about emotional intelligence, some of them new. We have reformulated our original ability model here guided by these principles, clarified earlier statements of the model that were unclear, and revised portions of it in response to current research. In this revision, we also positioned emotional intelligence amidst other hot intelligences including personal and social intelligences, and examined the implications of the changes to the model. We discuss the present and future (...) of the concept of emotional intelligence as a mental ability. (shrink)

A comparison is made between the Bohm trajectory and Feynman path approaches to the long-standing problem of determining the average lime taken for a particle described by the Schrödinger wave function ψ to tunnel through a potential barrier. The former approach follows simply and uniquely from the basic postulates of Bohm's causal interpretation of quantum mechanics; the latter is intimately related to the most frequently cited approaches based on conventional interpretations. Emphasis is given to the fact that fundamentally different transmission (...) (T)-reflection (R) decompositions, particlelike and wavelike respectively, are central to the two methods: ¦ψ¦2=[¦ψ¦2]T+[¦ψ¦2]R (Bohm trajectory approach); ψ=ψT+ψR (Feynman path approach). (shrink)

Ancillary care is care that research participants need that is not essential to make the research safe or scientifically valid and is not needed to remedy injuries that eventuate as a result of the research project itself. Ancillary care duties have recently been defended on the grounds of beneficence, entrustment, utility and consent. Justice has also been mentioned as a possible basis of ancillary care duties, but little attention has been paid to this approach. In this paper, the author seeks (...) to rectify this omission by arguing that ancillary care duties can be based on a principle of justice as rectification. (shrink)

Abstract Physiological psychology has its conceptual roots in stimulus?response behaviourism. The resurgence of cognitive concepts in mainstream psychology has led to a separation between the two, largely due to the failure of most cognitive theories to specify how their explanatory processes could be realised in the nervous system. Connectionism looks as if it may be able to bridge this gap. The problem is that connectionism takes a radically different view of the brain from that adopted in traditional physiological psychology. This (...) paper looks at some of the implications of connectionism for how physiological psychology should develop. It also looks at the implications of the findings of physiological psychology for connectionism. (shrink)

Recent research on the relations of personality to well-being shows that the people who are most healthy, happy and fulfilled are those who are high in all three of the character traits of self-directedness, cooperativeness, and self-transcendence as measured by the Temperament and Character Inventory. In the past, the healthy personality has often been considered to require only high self-directedness and high cooperativeness. However, now the self-centred behaviour of people who are low in self-transcendence is degrading the conditions needed for (...) sustainable life by all human beings. Consequently, human beings need to and can develop their capacity for self-transcendence in order to maintain their individual and collective well-being. (shrink)

Professor Austin explores four main areas in this paper. First of all he outlines the physical development of sex differentiation in the embryo. He develops this by describing the clinical manifestations of abnormality which can appear at that stage. Professor Austin points out that there are relatively few people with abnormalities and that those who do show homosexual tendencies are not noticeably different from the norm in terms of their sexual equipment and hormone levels. It is much more likely that (...) their psychological and social development has a greater influence in differentiating them sexually. The last section of the paper is a synopsis of society's reactions to homosexuality or bisexuality which term in Professor Austin's opinion is more accurate and descriptive of the condition. (shrink)
