A decade ago, leptin (from the greek lepto meaning ‘thin’) was identified as the product of the ob gene.1 This adipocyte‐derived hormone was found to suppress feeding and stimulate thermogenesis, and was thus proposed as a mediator in a negative feedback loop that controls body adiposity. This discovery led to a rapid revolution in the understanding of neurobiological mechanisms regulating obesity. However, while leptin's first life was as an adipostat, it is now known to have a wide range of additional (...) neuroendocrine, metabolic and behavioural functions in the CNS and periphery. Remarkably, the pleiotropic nature of the hormone continues to be extended with the recent publication of two papers that expand on leptin's neurobiological actions in the CNS.2,3 They indicate novel regulatory roles for the hormone in both synaptic plasticity and axon guidance. Crucially, in light of the rising incidence of obesity in modern society, both of the studies reveal leptin‐mediated links between nutrition and neurodevelopment, findings that have further implications for leptin's role in the regulation of energy homeostasis.

It is often assumed that pet ownership improves peoples’ wellbeing, but evidence of this pet effect has been mixed. We extended past research on pet personality, the pet effect, and value congruence to examine whether people perceive their pets to have humanlike values and if owner-pet values similarity has a positive effect on owners’ life satisfaction. In a large and diverse sample of Australian dog and cat owners, we find that people imbue their dogs and cats with humanlike values in (...) a way that reflects the theoretical circular structure of values. Importantly, perceptions of the values of dogs and cats differed in that dogs were perceived to prioritize more social-focus values, whereas cats were perceived to prioritize more personal-focus values. Additionally, we find that similarity in the values profile of dog owners and their dogs is positively associated with life satisfaction, but this was not the case for cats. However, when we examined associations between individual values similarity and life satisfaction, our results suggest a more complex and nuanced picture of both direct and indirect similarity effects.

For the successful achievement of evidence-based practice, clinicians, managers and purchasers need evidence on whether a particular intervention works and ways to judge the appropriateness of the outcome criteria and measures used. Guidance is needed on what outcome measure to use, especially within routine clinical care settings. Beginning with a re-clarification of the difference between a health status and an outcome measure, the paper presents an evaluative checklist for use by clinical audit and research staff to review outcome measures for (...) use in routine care settings. Central features include the user-centredness of the measure, its psychometric properties, feasibility of use and utility. The applicability of the checklist is illustrated for outcome measurement in diabetes and stroke care. A modified form of the checklist is proposed for use by the busy clinician as an aid to the critical review of research papers within the context of evidence-based practice and to aid health care practitioners' choice of which outcome measure(s) to use within routine clinical care.

A central question in neuroscience and psychology is how the mammalian brain represents the outside world and enables interaction with it. Significant progress on this question has been made in the domain of spatial cognition, where a consistent network of brain regions that represent external space has been identified in both humans and rodents. In rodents, much of the work to date has been done in situations where the animal is free to move about naturally. By contrast, the majority of (...) work carried out to date in humans is static, due to limitations imposed by traditional laboratory based imaging techniques. In recent years, significant progress has been made in bridging the gap between animal and human work by employing Virtual Reality (VR) technology to simulate aspects of real-world navigation. Despite this progress, the VR studies often fail to fully simulate important aspects of real-world navigation, where information derived from self-motion is integrated with representations of environmental features and task goals. In the current review, we provide a brief overview of animal and human imaging work to date, focusing on commonalties and differences in findings across species. Following on from this we discuss VR studies of spatial cognition, outlining limitations and developments, before introducing mobile brain imaging techniques and describe technical challenges and solutions for real-world recording. Finally, we discuss how these advances in mobile brain imaging technology, provide an unprecedented opportunity to illuminate how the brain represents complex multifaceted information during naturalistic navigation.

The issues involved in deciding whether to use artificial methods of delivering hydration and nutrition are often very difficult for patients, families, and health care providers. Once private and personal matters, these decisions now frequently involve the judicial system. Five years ago, Hospice of Washington recognized the need for a written policy and wrote the one published here. Its goal is to respect individual preferences and family concerns while addressing the nutrition and hydration needs of dying patients. The policy sets (...) parameters on the issue, provides basic information, and encourages crafting the most fitting resolution to each situation. (shrink)

Grainger, Joanne This article explores the proposed Victorian Medical Treatment (Physician Assisted Dying) Bill from a nursing perspective. Public trust of the nursing profession will be lessened with the introduction of any law that permits euthanasia or assisted suicide. In Australian society, care of the dying is a compelling social duty and responsibility. In health and social terms, this is known as palliative care, whereby the provision of physical, psychological, spiritual and emotional support to terminally ill people and their families (...) ensures that suffering at life's end is lessened and minimised.

This paper explores the rhetoric of obstetric ultrasound technology as it relates to the abortion debate, specifically the interpretation given to ultrasound images by opponents of abortion. The tenor of the anti-abortion approach is precisely captured in the videotape, Ultrasound:A Window to the Womb. Aspects of this videotape are analyzed in order to tease out the assumptions about the (female) body and about the access to truth yielded by scientific technology (ultrasound) held by militant opponents of abortion. It is argued (...) that the ultrasound images do not offer transparent confirmation of the ontological status of the embryo and fetus. Rather, the window of ultrasound is constructed through a complex combination of visual and verbal devices: ultrasound images, photographic images, verbal argument, and emotional appeal. (shrink)

A gathering of the available ancient diagnostic commentaries, difficult as they are, should allow for the discovery of many interesting insights into the production of knowledge in ancient Mesopotamia. The work under review is disappointing in this regard. The presentation is cumbersome and confusing. The translations are all too often inaccurate, as are the interpretations. All in all, the work represents a step or two backward from previous editions of the texts. With these defects corrected, however, these ancient commentaries have (...) much to offer the modern reader. (shrink)

Many commentators have contrasted the way that sociability is theorized in the writings of Mary Astell and Damaris Masham, emphasizing the extent to which Masham is more interested in embodied, worldly existence. I argue, by contrast, that Astell's own interest in imagining a constitutively relational individual emerges once we pay attention to her use of religious texts and tropes. To explore the relevance of Astell's Christianity, I emphasize both how Astell's Christianity shapes her view of the individual's relation to society (...) and how Masham's contrasting views can be analyzed through the lens of her charge that Astell is an “enthusiast.” In late seventeenth-century England, “enthusiasm” was a term of abuse that, commentators have recently argued, could function polemically to dismiss those deemed either excessively social or antisocial. By accusing Astell of enthusiasm, I claim, Masham seeks to marginalize the relational self that Astell imagines and to promote a more instrumental view of social ties. I suggest some aspects of Astell's thought that may have struck contemporaries as “enthusiastic” and contrast her vision of the self with Masham's more hedonistic subject. I conclude that, although each woman differently configures the relation between self and society, they share a desire to imagine autonomy within a relational framework. (shrink)

Marginalization has been used as a guiding concept for nursing research, theory and practice. Its properties have been identified and updated in 1994 and 1999, respectively. This article re-examines marginalization, considering it to be a concept that changes with pivotal historical events. The events of September 11, 2001, and the war between the US/UK and Iraq are such pivotal events. The notion of the linguistic habitus and symbolic violence as outlined by Bourdieu provide new insights about the dynamics of marginalization. (...) Specifically noted is the marginalization of persons and cultures based on their designation by the current US administration, and as interpreted through mainstream media, as actual or potential ‘terrorists’. A parallel situation in nursing is discussed, beginning with nursing's own marginality, related to the dynamics of symbolic violence. Nursing is argued to be vulnerable to having essential words and practices co-opted by dominant institutions and altered in meaning, that is, made incongruent with the discipline's emphasis on core values of confidentiality, equity and care. In response to marginalization and exteriorization those affected can use voice and testimony to ‘recreate the centre’. Suggestions for protecting our practices and philosophy are included. (shrink)

We develop a novel argument scheme tailored to debates surrounding public votes on a state action. It can be used to propose reasons for voting “yes” or “no” and allows for natural reconstructions of such debates. These reconstructions are of particular use to voters trying to weigh the pros and cons of the proposed state action. The scheme for proposing reasons helps answering two questions: What changes will the proposed state action bring with it? And are these changes good or (...) not? Using the scheme, we derive a three-layered structure of public debates surrounding votes that aides in constructing systematic and comprehensive overviews. The scheme for proposing reasons also lends itself to concise summaries for voter information and can be incorporated into more general deliberation dialogues. (shrink)

There is little empirical evidence showing a direct link between a capacity for statistical learning (SL) and proficiency with natural language. Moreover, discussion of the role of SL in language acquisition has seldom focused on literacy development. Our study addressed these issues by investigating the relationship between SL and reading ability in typically developing children and healthy adults. We tested SL using visually presented stimuli within a triplet learning paradigm and examined reading ability by administering the Wide Range Achievement Test (...) (WRAT-4; Wilkinson & Robertson, 2006). A total of 38 typically developing children (mean age of 9;5 years, range 6;4–12;5) and 37 healthy adults (mean age of 21 years, range 18–34) were assessed. In children, SL was significantly related to reading ability. Importantly, this relationship was independent of grade and also age. The adult data, too, revealed that SL was significantly related to reading ability. A regression analysis of the combined child and adult data revealed that SL accounted for a unique amount of variance in reading ability, after age and attention had been taken into consideration. For the first time, this study provides empirical evidence that a capacity for more effective SL is related to higher reading ability in the general population. (shrink)

This article examines Sarah Kofman's interpretation of Nietzsche in light of the claim that interpretation was for her both an articulation of her identity and a mode of deconstructing the very notion of identity. Faulkner argues that Kofman's work on Nietzsche can be understood as autobiographical, in that it served to mediate a relation to her self. Faulkner examines this relation with reference to Klein's model of the child's connection to its mother. By examining Kofman's later writings on Nietzsche alongside (...) her autobiography, this article contends that Kofman's defense of anti-Semitism in Nietzsche serves to fend off her own ambivalence about being Jewish.

This paper argues that the figure of the child performs a critical function for the middle-class social imaginary, representing both an essential “innocence” of the liberal individual, and an excluded, unconscious remainder of its project of control through the management of knowledge. While childhood is invested with affect and value, children’s agency and opportunities for social participation are restricted insofar as they are seen both to represent an elementary humanity and to fall short of full rationality, citizenship and identity. The (...) diverse permutations of this figure, as it develops in the middle-class imagination, are traced from the writings of John Locke to the films of Michael Haneke (via Charles Dickens and Henry James), to interrogate what this ambivalence regarding childhood reflects about middle-class, adult identity.

Advances in science have led to a new vision for toxicity testing based on human cell systems that will be more predictive, have higher throughput, cost less money, and be more comparable to real‐life exposures in humans, while using many fewer animals. This vision, embraced by leading scientific and regulatory groups, is a paradigm shift from animal‐based to human‐based testing that signals a major change in focus and promotes the development of new approaches to understanding the toxicity of chemicals in (...) humans. Information gained from these new approaches will likely affect other areas of research as well, leading to less reliance on animals in the future. (shrink)

Nietzsche’s relationship to his contemporaries, as expressed in his writings, was often figured by corporeal imagery evocative of disgust. For instance, in On the Genealogy of Morality Nietzsche declared himself to suffer from mankind—which he then proceeds to describe as “maggot”—or worm-like. Nietzsche’s philosophical project can be interpreted as a visceral protest against, and attempt to overcome, humanity. This paper argues that Nietzsche attempted through his writings to create a future community of like-constituted companions in his readers through a transmission (...) of affect and education in taste. This would-be "community" is premised on a curious affective dialectic that seeks to transform disgust for humanity into a pure movement of self-creation. The socio-political effects of this dialectic of disgust will be examined alongside Nietzsche's co-option of images of purity, in order to evaluate his response to modern nihilism. (shrink)

Testimony to Muzil: Hervé Guibert, Michel Foucault, and the “Medical Gaze” examines the fictional/autobiographical AIDS writings of the French writer Hervé Guibert. Locating Guibert's writings alongside the work of his friend Michel Foucault, the article explores how they echo Foucault's evolving notions of the “medical gaze.” The article also explores how Guilbert's narrators and Guibert himself resist and challenge the medical gaze; a gaze which particularly in the era of AIDS has subjected, objectified, and even sometimes punished the body of (...) the gay man. It is argued that these resistances to the gaze offer a literary extension to Foucault's later work on power and resistance strategies. (shrink)

This address uses the question “Is business ethics getting better?” as a heuristic for discussing the importance of history in understanding business and ethics. The paper uses a number of examples to illustrate how the same ethical problems in business have been around for a long time. It describes early attempts at the Harvard Business School to use business history as a means of teaching students about moral and social values. In the end, the author suggests that history may be (...) another way to teach ethics, enrich business ethics courses, and develop the perspective and vision in future business leaders. (shrink)

We contribute to the literature on ethics in the professions by theorizing how global mobility precipitates professional insecurity and constrained moral agency. We present our findings of a study of accountants migrating to Canada. Using postcolonial theory and relational/poststructuralist theories of identity and ethics, we contrast the experiences of marginalized and privileged migrant accountants to show how those with “diverse” social identities are not recognized by professionals in Canada and must seek recognition from Canadian colleagues, employers, and clients to reconstitute (...) their professional identities and moral agency. We discuss the implications of the exclusion and marginalization of professionals for migrants, the profession, and society more generally. (shrink)

This study examines how authentic leadership influences team performance via the mediating mechanism of team reflexivity. Adopting a self-regulatory perspective, we propose that authentic leadership will predict the specific team regulatory process of reflexivity, which in turn will be associated with two outcomes of team performance, effectiveness and productivity. Using survey data from 53 teams in three organizations in the United Kingdom and Greece and controlling for collective trust, we found support for our stated hypotheses with the results indicating a (...) significant fully mediated relationship. As predicted the self-regulatory behaviors inherent in the process of authentic leadership served to collectively shape team behavior, manifesting in the process of team reflexivity, which, in turn, positively predicted team performance. We conclude with a discussion of how this study extends theoretical understanding of authentic leadership in relation to teamwork and delineate several practical implications for leaders and organizations.

The frontispiece of Hobbes's Leviathan is justly renowned as a powerful visual advertisement for his political philosophy. Consequently, its rich imagery has been the subject of extensive scholarly commentary. Surprisingly, then, its gendered dimensions have received relatively limited attention. This essay explores this neglected facet of the frontispiece. I argue that the image initially appears to present a hypermasculine sovereign. However, upon closer inspection, and considered alongside Hobbes's economic theory, it yields to a reading of the sovereign as an ambiguously (...) gendered figure. Reading the frontispiece through the prism of gender and the economy reveals not a static image of unwavering male power but rather one of an equivocally-sexed creature teeming with life, contradictions, and complexities worthy of continued examination.
