Childhood obesity has become a public health epidemic, and currently a battle exists over how to frame and address this problem. This paper explores how public policy approaches can be employed to address obesity. We present the argument that obesity should be viewed as the consequence of a “toxic environment” rather than the result of the population failing to take enough “personal responsibility.” In order to make progress in decreasing the prevalence of obesity, we must shift our view of obesity (...) away from the medical model to a public health model . At the same time, we must be sensitive to the problem of weight bias.Potential obstacles to taking a public policy approach are identified, as well as suggestions on how to overcome them. (shrink)

After years of near total neglect, the problem of childhood obesity is now in the limelight. Terms like “epidemic,” “crisis,” and “emergency” are used frequently when describing the trend. Progress is defined with strong language and fueled by statistics such as the observation that this generation of children will be the first to live shorter lives than their parents. Multi-disciplinary journals such as the Journal of Law, Medicine & Ethics have dedicated symposiums to the issue, and conferences have been convened (...) not only by health professionals but by government agencies, the food industry, and even professionals who market to children. The seriousness of childhood obesity is no longer in doubt, and finally attention has turned to the more complex question – what must be done? (shrink)

Joint action, critical to human social interaction and communication, has garnered increasing scholarly attention in many areas of inquiry, yet its development remains little explored. This paper reviews research on the growth of joint action over the first 2 years of life to show how children become progressively more able to engage deliberately, autonomously, and flexibly in joint action with adults and peers. It is suggested that a key mechanism underlying the dramatic changes in joint action over the second year (...) of life is the ability to reflect consciously on oneself and one’s behavior and volition and correspondingly, on the behavior, goals, and intentions of others.

Abstract:Hiram J. McLendon (1919–2000) was an American philosopher who taught at Berkeley, Harvard and New York University. Awarded Harvard’s Sheldon Traveling Fellowship for 1946–47, he studied with Bertrand Russell that year at Trinity College, Cambridge. His assistance with the manuscript of Human Knowledge was acknowledged. His son, James McLendon, accompanied his parents and has kindly permitted this 1956 paper, as sent to Russell, to be published. The incident involving Wittgenstein, Popper and a poker is discussed. Russell’s letters in response (...) (which “delighted” McLendon) follow. The paper is an abbreviated version of a book manuscript entitled “The Philosopher among Professors” that he worked on for many years. He was also then working on a three-volume manuscript on Russell’s philosophic contributions, especially in epistemology, under the title of “Justifying Knowledge” (volume titles: “Revolution and Counterrevolution in Philosophy”, “Beyond the Mythic Way” and “Where Things Are”). Square-bracketed notes are editorial. (shrink)

If the new and rapidly expanding discipline of neuroethics is to have a signii cant impact on patient care, the neuroscience clinicians must become familiar with the discipline, and be competent and comfortable in applying its cognitive base and principles to clinical decisionmaking. Familiarity with and practical experience in the application of basic biomedical knowledge and principles to clinical decision- making in the neurosciences becomes the essential foundation on which to begin to integrate neuroethics into medical education. The place where (...) the building of this foundation and the initial exposure to neuroethics must begin is in the residency program. This article describes the approach developed in the neurology residency education program at the University of Calgary to move toward achieving this goal. The key elements for the development and successful implementation of the program are outlined and a brief overview of the topics covered in the sessions is described. (shrink)

Because we engage with the world and each other through our bodies and bodily movements, being able to represent one's own and others' bodies is fundamental to human perception, cognition and behaviour. This edited book brings together, for the first time, developmental perspectives on the growth of body knowledge in infancy and early childhood and how it intersects with other aspects of perception and cognition. The book is organised into three sections addressing the bodily self, the bodies of others and (...) integrating self and other. Topics include perception and representation of the human form, infant imitation, understanding biological motion, self-representation, intention understanding, action production and perception and children's human figure drawings. Each section includes chapters from leading international scholars drawn together by an expert commentary that highlights open questions and directions for future research. (shrink)

Carpendale & Lewis (C&L) stress the importance of social interaction for social understanding, but focus on the adult-child relationship. In the present commentary, we discuss the development of social understanding within early peer relationships. We argue that peer interaction stretches the limits of early social understanding, thereby providing both unique challenges and unique opportunities for constructing an understanding of others' minds.

In their account of the origins of human collaborative abilities, Tomasello et al. rely heavily on reasoning and evidence from adult–child collaborations. Peer collaborations are not discussed, but early peer collaborations differ from early adult–child collaborations. Describing and explaining the similarities and differences in shared intentionality with peers and adults will bring us closer to understanding the developmental mechanisms.

Cooperative peer play emerges in the second year of life. How applicable is Preston & de Waal's (P&deW's) model to the empathic processes in cooperative play? Empathic responses during peer play are more general than they propose, and more dependent on mental state understanding. Moreover, peer play forces children to reason about others' feelings, possibly serving as a unique mechanism for empathy development.

The empiricist bent of philosophy of science and epistemology over the past four decades has recently been challenged, partly by arguments that exploit the uncertainty about what precisely the given is. It is claimed that this uncertainty stems from the fact that all observation is theory-laden; different "enities" [[sic]] are said to be observed as the theory constituting them is varied. Observations therefore do not test theories. So-called tests are really circular arguments, if they confirm the theory, or question-begging, if (...) they disconfirm it. Such is roughly the line of argument advanced by the new philosophy of science. (shrink)
