Generalized anxiety disorder (GAD) and social phobia (SP) are major anxiety disorders identified by the Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV). They are comorbid, overlap in symptoms, yet present with distinct features (worry in GAD and fear of embarrassment in SP). Both have also been explained in terms of conditioning-based models. However, there is little reasoning currently to believe that GAD in adulthood reflects heightened conditionability or heightened threat processing—though patients with SP may show heightened processing (...) of social threat stimuli. Moreover, the computational architectures that maintain these disorders in adulthood are different. For GAD this may reflect the development of an inefficient “worrying” strategy of emotional regulation. For SP this appears to reflect the atypical processing of self-referential information.

Youths with disruptive behavior disorders and psychopathic traits showed reduced amygdala responses to fearful expressions under low attentional load but no indications of increased recruitment of regions implicated in top- down attentional control. These findings suggest that the emotional deficit observed in youths with disruptive behavior disorders and psychopathic traits is primary and not secondary to increased top- down attention to nonemotional stimulus features.

Today, health systems around the world are under pressure to create greater value for patients and society [81, p. 1, 119]; increasing access, improving client orientation and responsiveness, reducing medical errors and safety, restraining utilization via managed care, and implementing priority allocation of resources for high-burden health problems are examples of strategies towards this end. The quality paradigm by virtue of its strategic consumer focus and its methods for achieving operational excellence has proved an effective approach for creating higher value (...) in many sectors. If applied in a deliberate and holistic manner, the quality paradigm can bring about a more cost-effective organization of the health systems. In this article, we apply quality concepts to healthcare in a conceptual format; we characterize the health system’s customers and outputs with their quality dimensions. The product of this effort is a blueprint for a customer-driven health system which identifies six types of customers, nine types of outputs and the associated operations. As a preliminary step, a new analysis and definition of health and disease is provided. Rethinking the structure of health system in this manner and the related conceptual model can guide medical research, health sciences education, and health services policy, and help the practitioner to integrate all modern trends in healthcare delivery.

In this paper, we will consider the neuro-cognitive systems involved in mediating morality. Five main claims will be made. First, that there are multiple, partially separable neuro-cognitive architectures that mediate specific aspects of morality: social convention, care-based morality, disgust-based morality and fairness/justice. Second, that all aspects of morality, including social convention, involve affect. Third, that the neural system particularly important for social convention, given its role in mediating anger and responding to angry expressions, is ventrolateral prefrontal cortex. Fourth, that the (...) neural systems particularly important for care-based morality are the amygdala and medial orbital frontal cortex. Fifth, that while Theory of Mind is not a prerequisite for the development of affect-based 'automatic moral attitudes', it is critically involved in many aspects of moral reasoning. (shrink)

This study investigates the ability of individuals with psychopathy to perform passive avoidance learning and whether this ability is modulated by level of reinforcement/punishment. Nineteen psychopathic and 21 comparison individuals, as defined by the Hare Psychopathy Checklist Revised (Hare, 1991), were given a passive avoidance task with a graded reinforcement schedule. Response to each rewarding number gained a point reward specific to that number (i.e., 1, 700, 1400 or 2000 points). Response to each punishing number lost a point punishment specific (...) to that number (i.e., the loss of 1, 700, 1400 or 2000 points). In line with predictions, individuals with psychopathy made more passive avoidance errors than the comparison individuals. In addition, while the performance of both groups was modulated by level of reward, only the performance of the comparison population was modulated by level of punishment. The results are interpreted with reference to a computational account of the emotional learning impairment in individuals with psychopathy. (shrink)

The appendages of Drosophila develop from the imaginal discs. During the extensive growth of these discs cell lineages are for the most part unfixed, suggesting a strong role for cell‐cell interactions in controlling the final pattern of differentiation. However, during early and middle stages of development, discs are subdivided by strict lineage restrictions into a small number of spatially distinct compartments. These compartments appear to be maintained by stably inheriting states of gene expression; the compartmentspecific expression of two such ‘selector’ (...) ‐ like genes, engrailed and apterous, are critical for anterior‐posterior and dorso‐ventral compartmentalization, respectively. Recent work suggests that one purpose of compartmentalization is to establish regions of specialized cells near compartment boundaries via intercompartmental induction, using molecules like the hedgehog protein. Thus, compartments can act as organizing centers for patterning within compartments. Evidence for non‐compartmental patterning mechanisms will also be discussed. (shrink)

We question whether empathy is mediated by a unitary circuit. We argue that recent neuroimaging data indicate dissociable neural responses for different facial expressions as well as for representing others' mental states (Theory of Mind, TOM). We also argue that the general empathy disorder considered characteristic of autism and psychopathy is not general but specific for each disorder.

Over the years, phenomenology has provided illuminating descriptions of discrimination, with its mechanisms and effects being thematised at the most basic levels of embodiment, (dis)orientation, selfhood, and belonging. What remains somewhat understudied is the lived experience of the discriminator. In this paper I draw on Husserl's phenomenological account of normality to reflect on the ways in which we discriminate at the prereflective levels of perceptual experience and bodily being. By critically reflecting on the intentional structures undergirding discriminatory practices, I argue (...) that discrimination is characteristic of a naïve normalising attitude which is habitually interested in securing a familiar experience of a static normality. I first demonstrate how this attitude problematically tends to reproduce, enforce, and further sediment discriminatory and exclusionary norms. Further, I provide an internal critique which problematises discrimination—without recourse to external normative standards—on three fronts: as epistemically unproductive, experientially obscuring, and normatively non-instantiating. In discriminatory acts we see an abnormal refusal to enrich, revise, and genetically establish new normative commitments, new ways of seeing, and a new normality. (shrink)

BackgroundThere is increasing need for peer reviewers as the scientific literature grows. Formal education in biostatistics and research methodology during residency training is lacking. In this pilot study, we addressed these issues by evaluating a novel method of teaching residents about biostatistics and research methodology using peer review of standardized manuscripts. We hypothesized that mentored peer review would improve resident knowledge and perception of these concepts more than non-mentored peer review, while improving review quality.MethodsA partially blinded, randomized, controlled multi-center study (...) was performed. Seventy-eight neurology residents from nine US neurology programs were randomized to receive mentoring from a local faculty member or not. Within a year, residents reviewed a baseline manuscript and four subsequent manuscripts, all with introduced errors designed to teach fundamental review concepts. In the mentored group, mentors discussed completed reviews with residents. Primary outcome measure was change in knowledge score between pre- and post-tests, measuring epidemiology and biostatistics knowledge. Secondary outcome measures included level of confidence in the use and interpretation of statistical concepts before and after intervention, and RQI score for baseline and final manuscripts.ResultsSixty-four residents (82%) completed initial review with gradual decline in completion on subsequent reviews. Change in primary outcome, the difference between pre- and post-test knowledge scores, did not differ between mentored (−8.5%) and non-mentored (−13.9%) residents (p = 0.48). Significant differences in secondary outcomes (using 5-point Likert scale, 5 = strongly agree) included mentored residents reporting enhanced understanding of research methodology (3.69 vs 2.61; p = 0.001), understanding of manuscripts (3.73 vs 2.87; p = 0.006), and application of study results to clinical practice (3.65 vs 2.78; p = 0.005) compared to non-mentored residents. There was no difference between groups in level of interest in peer review (3.00 vs 3.09; p = 0.72) or the quality of manuscript review assessed by the Review Quality Instrument (RQI) (3.25 vs 3.06; p = 0.50).ConclusionsWe used mentored peer review of standardized manuscripts to teach biostatistics and research methodology and introduce the peer review process to residents. Though knowledge level did not change, mentored residents had enhanced perception in their abilities to understand research methodology and manuscripts and apply study results to clinical practice.

This paper surveys interdisciplinary research on gratitude that has been conducted since the review paper translated into German in this issue ‘Recent work on the concept of gratitude in philosophy and psychology’, was published in the Journal of Value Inquiry in 2013. We share progress on our subsequent research, and report on key developments in the field. We revisit familiar themes regarding conditions placed on gratitude, the structure and moral value of gratitude, and the pedagogical implications of research on gratitude, (...) addressing the issue of how the virtue of gratitude should be promoted and taught. As befits a collection dedicated to exploring gratitude’s potential ‘shadow’, we consider again the valence of gratitude and whether it is as quintessentially positive as many have assumed. (shrink)

Various social animal species have been noted to inhibit aggressive attacks when a conspecific displays submission cues. Blair (1993) has suggested that humans possess a functionally similar mechanism which mediates the suppression of aggression in the context of distress cues. He has suggested that this mechanism is a prerequisite for the development of the moral/conventional distinction; the consistently observed distinction in subject's judgments between moral and conventional transgressions. Psychopaths may lack this violence inhibitor. A causal model is developed showing (...) how the lack of this mechanism would explain the core behavioural symptoms associated with the psychopathic disorder. A prediction of such a causal model would be that psychopaths should fail to make the moral/conventional distinction. This prediction was confirmed. The implication of this finding for other theories of morality is discussed. (shrink)

Akira Kurosawa is arguably known as the director who opened up Japanese film to Western audiences and following his death in 1998, a process of reflection has begun about his life's work as whole and its legacy to the cinema and its global audiences. Rashomon has arguably become the best known Japanese film, ever. After this, his twelfth film, Kurosawa's reputation was firmly established in international cinema, and Rashomon continues to be discussed and imitated more than sixty years after its (...) first screening. This volume addresses issues beyond the realm of Rashomon within film studies, and to do with the Rashomon effect which itself has become a widely recognized English term referring to significantly different perspectives and interpretations of different eyewitnesses to the same dramatic event. The dual figures of ripples and circles comprise the organizing image and principle of this book as each chapter addresses either the movement of ripples, representing the continuing and vibrant influence of Rashomon effects into the twenty-first century, or of circles, representing specific events, such as the publication of a new script, a particular production, or a remake.

This paper will address the political and ethical ramifications of Derrida's concern for friendship in relation to his concerns with the future of democracy, rights of hospitality and cosmopolitics. The questions addressed read as follows: Is there a way we can get beyond this stance which not only consolidates a friendship of the ‘perhaps’ with a friendship of the promise, but also implicates their consolidation with the very future of what we today call democracy? Is there a way in which (...) we can substantiate something more than a romanticized call for a future integration of friendship and democracy while avoiding the pitfalls of on one hand, substantiating a model of friendship for politics or, on the other, offering a disguised and naïve return to a metaphysics of friendship as the saving grace of social unity? Through a close reading of the conclusion to Politics of Friendship as well as his concerns with friendship in Spectres of Marx and Rogues: Two Essays on Reason it will be argued that Derrida's insistence on the future of friendship is bound up with the notion of an ethical promise to the thought of friendship as the condition for its political and ethical relevance.

In recent years, misogyny has become a central concept in philosophy as well as an established concept in public discourse and political policy. But where is misogyny’s supposed counterpart, namely, misandry? In this paper I argue for an ameliorative analysis of "misandry", arguing that it can be reformulated in an effort to reclaim it from its misogynistic weaponisation. The term "misandry" is used almost exclusively as a misogynistic rhetorical device for attributing unjust anger, hatred, or other similar emotions to a (...) speaker, thereby undermining their epistemic authority. Rather than dismissing the term as conceptually flawed and politically problematic, I argue that we ought to ameliorate misandry to instead refer to a felt anger, hostility, or fear toward the patriarchal social order and its valorisation and/or expression in misogynistic and machismo behaviour. To support these claims, I begin with a discussion of Kate Manne's analysis of misogyny before reflecting on how this can inform our understanding of misandry. I then demonstrate the various ways in which misandry is rhetorically deployed as a means of silencing speakers that express dissent against the patriarchy. Following this, I argue that we should ameliorate the term, not only to undermine these misogynistic practices, but also to articulate a legitimate affective and reactive attitude against the patriarchal imposition of a hierarchical gender binary.

Fifty years ago this summer, the Uniform Anatomical Gift Act was adopted by the National Conference of Commissioners on Uniform State Laws and approved by the American Bar Association. The UAGA has provided a sound and stable legal platform on which to base an effective nationwide organ donation system. The cardinal principles of altruism, autonomy, and public trust are still important. At a time when confidence and trust in our government and many private institutions has declined, maintaining trust and confidence (...) in our health care system and its commitment to “first, do no harm” has never been more important. Any policies that override these core ethical principles could cause irreparable damage to the public's faith in our transplant system. While progress has been made to increase organ registration and the number of organs transplanted, much more must be done to realize the potential of life‐saving therapy without jeopardizing ethical principles.

Ten years ago, when I was president and chief executive officer of Rady Children's Hospital in San Diego, if you had asked me about our commitment to environmental sustainability or about the hospital's carbon footprint, I would have given you a blank look. The issues were simply not on my radar screen. And that was true of most health care leaders.The good news? Environmental sustainability is becoming a health care priority, and exciting progress is occurring. In Greening Health Care: How (...) Hospitals Can Heal the Planet, Kathy Gerwig eloquently relates how one leading large health care system, Kaiser Permanente, achieved remarkable results in responding to the environmental health challenge over the past several years.

Drawn from the photography journal Photofile, this volume collects work by prominent critics, theorists, and cultural commentators about many of Australia's most significant photoartists. It illustrates how, located between the realms of fine art and visual culture, photography has underpinned many key developments in our understanding of both during the last decades of the twentieth century. The essays investigate a wide range of subjects including documentary photography, race and representation, and photography and national identity.

In this paper, my aim is to develop a phenomenological understanding of discrimination from the perspective of the discriminator. Since early existential phenomenology, the phenomenon of discrimination has received a great deal of attention. While much of this work has focused on the experience of the discriminatee, recent scholarship has begun to reflect on the intentional structures on the side of the discriminator. In a contribution to this trend, I argue that our sense of what is (ab)normal plays a constitutively (...) significant role in the reiteration and reinforcement of harmful discriminatory practices. More specifically, I argue that Husserl's distinction between two forms of normality, namely, concordance-normality [Einstimmigkeit] and optimal-normality [Optimalität], is an important tool for illuminating otherwise overlooked aspects of the discriminator's experience. I achieve this by demonstrating how these two notions of normality play distinct constitutive roles when comparing deliberate acts of discrimination committed with malintent, compared with more primordial, habitual, and prereflective expectations which are already discriminatory in nucleo. I argue that at the heart of discriminatory practices there is a naïve, normalizing attempt to stabilize concordance at the expense of critical self-reflection, normative revisions, and enriched horizons of expectation. In doing so, this paper provides a novel and important contribution to philosophical discussions surrounding discrimination. (shrink)

Phenomenological discussions of sociality have long been concerned with the relations between the I, the You, and the We. Recently, dialogue between phenomenology and analytic philosophical work on collective intentionality has given rise to a corpus of literature oriented around the first-person plural 'we'. In this paper, I demonstrate how these dominant accounts of the 'we' are not exhaustive of first-person plural experiences as such. I achieve these aims by arguing for a phenomenological distinction between an experience of being part (...) of a 'we' compared to an experience of being part of an 'us'. To have a 'we-experience' there must be a plurality of (unified) subjects sharing in an experience together such that the experience has the phenomenal character of being ours. An 'us-experience', on the other hand, requires the experiential salience of an external 'Third' in a way which is constitutively significant. Drawing on Sartrean social ontology, I argue that the 'us' is distinct from the 'we' on three levels, all of which pertain to the constitutive and unifying role of the Third. I then outline two forms of us-experiences: (1) the experience of being grouped and (2) the experience of apprehending one's seriality. (shrink)

Using measures developed by Singhapakdi et al. (1996, Journal of Business ethics 15, 1131–1140) the perceived importance of ethics and social responsibility (PRESOR) is measured among MBA students in the United States, Malaysia and Ukraine revealing a stockholder view and two stakeholder views. Relativism and Idealism are also measured. The scores of MBA students are compared among each other and with those of the U.S. managers who were part of the original study. Managers'' scores tend to be significantly higher on (...) the Stockholder and Stakeholder II views, and much lower on Relativism than the MBA students. The Malaysian MBA students scored higher than did the American MBA students on Relativism, Idealism and the Stockholder view. The Ukrainian MBA students'' scores on the three PRESOR factors are generally similar to those of the American MBAs, while they had the highest scores of any group on the Relativism scale. Overall, the patterns of responses, as much as the significant differences on specific scales, support the notion that culture, however defined, affects both values and ethics. Several directions for future research are identified.''. (shrink)

To the Editor: It was with great interest that our Canadian Palliative Sedation Therapy Guideline working group read Jeffrey Berger's recent article ("Rethinking Guidelines for the Use of Palliative Sedation," May-June 2010). Given our own group's efforts to develop national guidelines, we have rethought the issue of palliative sedation therapy several times over the past year.The use of clear and concise definitions is fundamental to the development of any consensus guidelines on this topic. In the article, the term "palliative sedation (...) to unconsciousness," or PSU, implies the concerning assumption that sedation will knowingly be to unconsciousness in the palliative case under consideration. This conflicts with .. (shrink)

Numerous recommendations and guidelines aim to improve the quality, timeliness and transparency of medical publications. However, these guidelines use ambiguous language that can be challenging to interpret, particularly for speakers of English as a second language. Cultural expectations within the Asia-Pacific region raise additional challenges and several studies have suggested that awareness and application of ethical publication practices in the Asia-Pacific region is relatively low compared with other regions. However, guidance on applying ethical publication practice guidelines in the Asia-Pacific region (...) is lacking. This commentary aims to improve publication practices in the Asia-Pacific region by providing guidance on applying the 10 principles of the Good Publication Practice 3 (GPP3) guidelines and the International Committee of Medical Journal Editors (ICMJE) criteria for authorship. Recommendations are provided for encore presentations, applying the ICMJE authorship criteria in the context of regional cultural expectations, and the role of study sponsors and professional medical writers. Ongoing barriers to compliance with guidelines are also highlighted, and additional guidance is provided to support authors submitting manuscripts for publication. The roles of regional journals, regulatory authorities and professional bodies in improving practices are also discussed. (shrink)

Care is a feature of all of our lives, all of the time. An analysis of Scotland's Curriculum for Excellence reveals that care and caring permeate complex dimensions of life in and after school and we ask here, if, on some accounts, care can do the work required of it. Acknowledging the significance of her contribution to care, we focus on the work of Nel Noddings suggesting that she pays insufficient attention to other emotions implicated in the work of morally (...) appropriate care. We argue here that Noddings' version of care would benefit from the support of an ethical theory of the emotions, including a moralized form of compassion, if care in schools is to be both better understood and more likely realised.

People who judge that a wrongdoer’s behaviour is determined are disposed, in certain cases, to judge that the wrongdoer cannot be responsible for his behaviour. Some try to explain this phenomenon by arguing that people are intuitive incompatibilists about determinism and moral responsibility. However, Peter Strawson argues that we excuse determined wrongdoers because judging that someone is determined puts us into a psychological state – ‘the objective stance’ – which prevents us from holding them responsible, not because we think that (...) determined wrongdoers cannot be responsible. Two studies were completed to test the claim that the objective stance prevents us from judging wrongdoers responsible. Implicit association measures revealed that participants primed in the objective stance appraised a wrongdoer more positively, but as no less blameworthy, than those neutrally primed. These findings raise doubts about Strawson’s explanation of our tendency to excuse determined wrongdoers. (shrink)

The paper's thesis is that dialogue is not an adequate model for all types of argument. The position of Walton is taken as the contrary view. The paper provides a set of descriptions of dialogues in which arguments feature in the order of the increasing complexity of the argument presentation at each turn of the dialogue, and argues that when arguments of great complexity are traded, the exchanges between arguers are turns of a dialogue only in an extended or metaphorical (...) sense. It argues that many of the properties of engaged back-and-forth exchanges of paradigmatic argument dialogues are not found in ‘solo’ arguments, and that at least some of the norms appropriate to the former type of argument, such as some of the pragma-dialectical rules of van Eemeren and Grootendorst's model, do not apply to the latter.

In this paper I review a number of Govier’s criticisms of the standard view of logic at the time she was developing her views about the nature of logic as it applies to the critique of arguments in natural language and the development of ways to teach skills in such critique. I argue that the concept of informal logic has emerged at least in part from those criticisms and Govier’s positive alternatives.

The notion that God and the world are mutually interdependent is generally taken to be unique to twentieth-century process theology. Largely, process thinkers have focused on classical theists, rather than the mystics. My thesis, however, is that, centuries before process came along, there were Western mystical concepts stressing that God needed the universe in order to become conscious and complete. In support of my thesis, I will provide a synopsis of the doctrines of God as found in mystics such as (...) Boehme, Dionysius, Eckhart, and then show how Whitehead’s aesthetic provides a coherent philosophical psychology of ecstasy. Key words: aesthetic experience, causal efficacy, consequent nature of God, ecstasy, feeling, German Romanticism, primordial nature of God, reformed subjectivist principle, Nicht, unconscious experience.

In lieu of an abstract, here is a brief excerpt of the content:What Emotional Responding Is to Blame It Might Not Be to ResponsibilityR. J. R. Blair (bio)Keywordsblame, responsibility, emotional responses, psychopathyIn this interesting paper, Levy argues that by failing the moral/conventional distinction task (Blair 1995), individuals with psychopathy show a fundamental inability to categorize moral harms and as such their moral responsibility for their actions is reduced. He argues that, although we might still wish to incarcerate such (...) individuals to prevent them inflicting further harm on others, we should be less enthusiastic to blame them for their actions.In many respects, I agree with much of Levy's treatise. I certainly do not regard ascriptions of blame as useful in my own work with this population. I believe that our goal should be to fully understand the nature of their emotional deficit to be able to treat it similarly to other researchers who work to treat other emotional disorders. To me, Levy's argument appears sound.However, I offer three considerations and raise questions within these considerations that might further the debate. First, not all rules involve care-based emotional responses to victims. As Levy notes, this is the origin of the moral/conventional distinction. The problem here is that we do consider someone responsible if they break a conventional transgression. The student talking in class is generally considered blameworthy for this action as long as they knew that the rule of not talking during the lesson applied to that classroom. Yet, there is no victim and no care-based emotional response. Here, the only thing necessary to ascribe blame and responsibility is that the individual knew that a rule exists. Given this holds for conventional transgressions, why must we necessarily make a special case, with respect to responsibility, for moral transgressions?I believe that Levy is fully aware of this concern. He specifically makes reference to moral responsibility and writes that:the kind and degree of wrongness, and therefore blame, which attaches to infringements of the rules [against double parking or line-jumping] is very different, and usually much less significant, than the kind and degree attaching to moral wrongs. For psychopaths, all offences are merely conventional, and therefore—from their point of view—none of them are all that serious.(2007, p. 132)But the danger here is that issues of blame and responsibility may become highly relativistic and hinge on the strength of the emotional reaction. This is a problem because, although we might judge someone as more blameworthy if he intentionally [End Page 149] runs over five people rather than one, do we really consider that there is a distinction in moral responsibility between these two cases? If not, might not responsibility relate to factual knowledge of the existence of the rule against the transgression rather than the emotional response to the transgression?Second, there is considerable debate regarding whether psychopathy represents a taxon or a continuum (e.g., Vasey et al. 2005; Edens et al. 2006). Assuming it does represent a continuum, then we have an additional concern. How little of an emotional response to the transgression reduces one's moral responsibility and blame? Is it only the very reduced (although usually not absent) levels of emotional response that are shown by individuals with psychopathy? Or should we consider moral responsibility and blame proportional to the level of the emotional response? If this latter option is adopted, then what should we do about individuals who show heightened emotional responses, for example, patients with specific anxiety disorders (Rauch, Shin, and Wright 2003)? There are already some data that inhibited children (a developmental precursor to some anxiety disorders; Kagan and Snidman 1999) show heightened conscience development (Asendorpf and Nunner-Winkler 1992). If such children commit moral transgressions, should we regard them as more morally responsible and more blameworthy than regular folks?Third, the issue of intention received little attention in this paper. I have been considered to show a similar lack of attention to intention in the past (Nichols 2002) and, moreover, in some respects the issue was of limited concern given Levy's main goals. However, I mention it because so much of whether we consider someone responsible for their actions and... (shrink)

ABSTRACT:Since the dawn of capitalism, corporations have been regarded by the law as separate legal “persons.” Corporate “personhood” has nonetheless remained controversial, and our understanding of corporate personhood often influences our thinking about the social responsibilities of corporations. This essay, written in honor of Prof. Thomas Donaldson, explores the tension in recent decisions by the U.S. Supreme Court and the Delaware Chancery Court about what corporations are, whose interests they serve, and who gets to make decisions about what they do. (...) These decisions suggest that the law does not unequivocally support Donaldson’s vision of corporations as “moral” persons. (shrink)

Lexical ambiguity—the phenomenon of a single word having multiple, distinguishable senses—is pervasive in language. Both the degree of ambiguity of a word (roughly, its number of senses) and the relatedness of those senses have been found to have widespread effects on language acquisition and processing. Recently, distributional approaches to semantics, in which a word's meaning is determined by its contexts, have led to successful research quantifying the degree of ambiguity, but these measures have not distinguished between the ambiguity of words (...) with multiple related senses versus multiple unrelated meanings. In this work, we present the first assessment of whether distributional meaning representations can capture the ambiguity structure of a word, including both the number and relatedness of senses. On a very large sample of English words, we find that some, but not all, distributional semantic representations that we test exhibit detectable differences between sets of monosemes (unambiguous words; N = 964), polysemes (with multiple related senses; N = 4,096), and homonyms (with multiple unrelated senses; N = 355). Our findings begin to answer open questions from earlier work regarding whether distributional semantic representations of words, which successfully capture various semantic relationships, also reflect fine‐grained aspects of meaning structure that influence human behavior. Our findings emphasize the importance of measuring whether proposed lexical representations capture such distinctions: In addition to standard benchmarks that test the similarity structure of distributional semantic models, we need to also consider whether they have cognitively plausible ambiguity structure.

Human allografts for life-threatening organ failure have been demonstrated to be lifesaving and are now considered to be standard of care for many conditions. Transplantation of non-vital anatomic body parts has also been accomplished. Hand transplantation after limb loss in adults has been shown to offer some promising benefits in both functional and psychological measures in preliminary studies. It has been suggested to expand eligibility criteria to include minors, with one such operation having already been performed. With this in mind, (...) we examine the current state of hand transplantation research in the context of available alternatives. We examine the ethics of carrying out these operations in minors, including under the protections of clinical research. We argue that children should not be considered for this surgery due to the substantial risks of immunosuppressive medication, the likelihood that the graft will need to be replaced during the patient’s lifetime and the lack of significant compensatory advantages over modern prosthetics.
