Functional human brain mapping is commonly performed during invasive monitoring with intracranial electroencephalographic electrodes prior to resective surgery for drug­ resistant epilepsy. The current gold standard, electrocortical stimulation mapping, is time ­consuming, sometimes elicits pain, and often induces after discharges or seizures. Moreover, there is a risk of overestimating eloquent areas due to propagation of the effects of stimulation to a broader network of language cortex. Passive iEEG spatial-temporal functional mapping has recently emerged as a potential alternative to ESM. However, (...) investigators have observed less correspondence between STFM and ESM maps of language than between their maps of motor function. We hypothesized that incongruities between ESM and STFM of language function may arise due to propagation of the effects of ESM to cortical areas having strong effective connectivity with the site of stimulation. We evaluated five patients who underwent invasive monitoring for seizure localization, whose language areas were identified using ESM. All patients performed a battery of language tasks during passive iEEG recordings. To estimate the effective connectivity of stimulation sites with a broader network of task-activated cortical sites, we measured cortico-cortical evoked potentials elicited across all recording sites by single-pulse electrical stimulation at sites where ESM was performed at other times. With the combination of high gamma power as well as CCEPs results, we trained a logistic regression model to predict ESM results at individual electrode pairs. The average accuracy of the classifier using both STFM and CCEPs results combined was 87.7%, significantly higher than the one using STFM alone, indicating that the correspondence between STFM and ESM results is greater when effective connectivity between ESM stimulation sites and task-activated sites is taken into consideration. These findings, though based on a small number of subjects to date, provide preliminary support for the hypothesis that incongruities between ESM and STFM may arise in part from propagation of stimulation effects to a broader network of cortical language sites activated by language tasks, and suggest that more studies, with larger numbers of patients, are needed to understand the utility of both mapping techniques in clinical practice.

This volume explores how Catholicism began and continues to open its doors to the wider world and to other confessions in embracing ecumenism, thanks to the vision and legacy of the Second Vatican Council. It explores such themes as the twentieth century context preceding the council; parallels between Vatican II and previous councils; its distinctively pastoral character; the legacy of the council in relation to issues such as church-world dynamics, as well as to ethics, social justice, economic activity. Several chapters (...) discuss the role of women in the church before, during, and since the council. Others discern inculturation in relation to Vatican II. The book also contains a wide and original range of ecumenical considerations of the council, including by and in relation to Free Church, Reformed, Orthodox, and Anglican perspectives. Finally, it considers the Council’s ongoing promise and remaining challenges with regard to ecumenical issues, including a groundbreaking essay on the future of ecumenical dialogue by Cardinal Walter Kasper.

ObjectiveBulimia nervosa and binge eating disorder are eating disorders characterized by recurrent binge eating episodes. Overlap exists between ED diagnostic groups, with BE episodes presenting one clinical feature that occurs transdiagnostically. Neuroimaging of the responses of those with BN and BED to disorder-specific stimuli, such as food, is not extensively investigated. Furthermore, to our knowledge, there have been no previous published studies examining the neural response of individuals currently experiencing binge eating, to low energy foods. Our objective was to examine (...) the neural responses to both low energy and high energy food images in three emotive categories in BN and BED participants.MethodsNineteen females with BN or BED, comprising the binge eating group, and 19 age-matched healthy control ’s completed thorough clinical assessment prior to functional MRI. Neural response to low energy and high energy foods and non-food images was compared between groups using whole-brain exploratory analyses, from which six regions of interest were then selected: frontal, occipital, temporal, and parietal lobes; insula and cingulate.ResultsIn response to low energy food images, the BEG demonstrated differential neural responses to all three low energy foods categories compared to HCs. Correlational analyses found a significant association between frequency of binge episodes and diminished temporal lobe and greater occipital lobe response. In response to high energy food images, compared to HC’s, the BEG demonstrated significantly decreased neural activity in response to all high energy food images. The HC’s had significantly greater neural activity in the limbic system, occipital lobe, temporal lobe, frontal lobe, and limbic system in response to high energy food images.ConclusionResults in the low energy food condition indicate that binge frequency may be related to increased aberrant neural responding. Furthermore, differences were found between groups in all ROI’s except the insula. The neural response seen in the BEG to disgust food images may indicate disengagement with this particular stimuli. In the high energy food condition, results demonstrate that neural activity in BN and BED patients may decrease in response to high energy foods, suggesting disengagement with foods that may be more consistent with those consumed during a binge eating episode.

Each annual Ontology Summit initiative makes a statement appropriate to each Summit’s theme as part of our general advocacy designed to bring ontology science and engineering into the mainstream. The theme this year is "Towards an Open Ontology Repository". This communiqué represents the joint position of those who were engaged in the year's summit discourse on an Open Ontology Repository (OOR) and of those who endorse below. In this discussion, we have agreed that an "ontology repository is a facility where (...) ontologies and related information artifacts can be stored, retrieved and managed." -/- We believe in the promise of semantic technologies based on logic, databases and the Semantic Web, a Web of exposed data and of interpretations of that data (i.e., of semantics), using common standards. Such technologies enable distinguishable, computable, reusable, and sharable meaning of Web and other artifacts, including data, documents, and services. We also believe that making that vision a reality requires additional supporting resources and these resources should be open, extensible, and provide common services over the ontologies. (shrink)

In 1911, Drs John Freeman and Leonard Noon published an account of a novel treatment for hay fever. Their method of desensitisation consisted of injecting increasing doses of an extract of pollen subcutaneously until the hypersensitivity reaction was diminished or abolished. Over subsequent decades, desensitisation established itself as the cornerstone of clinical allergy in both England and the United States, at least until the advent of novel pharmaceutical agents in the 1950s and 1960s. Although British allergists such as Noon and (...) Freeman were aware of conceptual developments within European immunology and pathology (such as the identification of anaphylaxis by Richet and Portier or von Pirquet's coining of the term allergy), their approach to hay fever was driven by more immediate pragmatic, and indeed financial, considerations. Freeman's immersion in the problems of hay fever and asthma and his pioneering use of allergen desensitisation or immunotherapy were shaped by his adherence to the convictions and bacteriological practices of his principal at St Mary's Hospital, Almroth Wright, and by the drive to produce commercial vaccines which would help to subsidise the experimental and therapeutic work at St Mary's. The aim of this paper is to explore early twentieth-century approaches to hay fever and other allergic diseases by tracing the intellectual and institutional origins of clinical allergy in Britain.

This chapter discusses the features of a hybrid expressivist view that has the resources to straightforwardly address issues about logical embedding and the connection between moral judgment and motivation. Following Mark Schroeder’s work in assessing the merits of current hybrid views and proposals made by Dan Boisvert, Michael Ridge, and David Copp, it briefly reviews why the hybrid expressivist may be optimistic about “having it both ways.” However, it argues that the current set of assumptions that lead to optimism (...) also lead to a kind of entangling problem. This arises from assumptions about the generalized structure of the mental states associated with moral thought and language. In response it proposes that agents can possess generalized noncognitive attitudes toward types rather than propositions involving universals. The chapter suggests that this modified hybrid expressivism can explain the connection between morality and motivation without being committed to the strongest forms of internalism. (shrink)

The Situationist International (1957-1972) was a small group of communist revolutionaries, originally organised out of the West European artistic avant-garde of the 1950s. The focus of my thesis is to explain how the Situationist International (SI) became a group able to exert a considerable influence on the ultra-left criticism that emerged during and in the wake of the May movement in France in 1968. My wager is that the pivotal period of the group is to be found between 1960 and (...) 1963, a period marked by the split of 1962. Often this is described as the transition of the group from being more concerned with art to being more concerned with politics, but as I will argue this definitional shorthand elides the significance of the Situationist critique of art, philosophy and politics. The two axes of my thesis are as follows. First, that the significant minority in the group which carried out the break of 1962, identified a homology between the earlier Situationist critique of art — embodied in the Situationist ‘hypothesis of the construction of situations’ — and Marx’s critique and supersession of the radical milieu of philosophy from which he emerged in the mid- 1840s. This homology was summarised in the expression of the Situationist project as the ‘supersession of art’ (dépassement de l’art). Secondly, this homology was practically embodied in the resolution of the debates over the role of art in the elaboration of the Situationist hypothesis, which had been ongoing since 1957. However, it was the SI’s encounter with the ultra-left group Socialisme ou Barbarie that would prove decisive. Via Guy Debord’s membership, the group was exposed to both the idea of a more general revolutionary criticism, but also ultimately what was identified as the insufficiently criticised ‘political militancy’ of this group. Indeed, in the ‘political alienation’ found in Socialisme ou Barbarie, a further homology was established between the alienation of the political and artistic avant-gardes. This identity would prove crucial to the further elaboration of the concept of ‘spectacle’. By way of an examination of the peculiar and enigmatic ‘Hamburg Theses’ of 1961, and the relationship between these ‘Theses’ and the Situationist criticism of art and politics worked out over the first five years of the group, I will argue that the break in 1962 should be conceived as one against politics as much as art (rather than just the latter, as it is more often represented). Additionally, I will outline how the SI, through the paradoxical reassertion of their artistic origins, attempted to synthesise their criticism of art with the recovery of the work of Marx beyond its mutilation as Marxism. Indeed, it was the synthesis of these critiques that enabled the considerable development of the concept of ‘spectacle’, opening the way to the unique influence the SI exerted in the re-emergence of a revolutionary movement at the end of the 1960s.

La distinción dicotómica entre agentes y pacientes morales está ampliamente reconocida y bien asentada en filosofía moral. Los animales, en el caso de ser considerados como poseedores de estatuto moral alguno, son, casi invariablemente, reconocidos como pacientes morales más que como agentes. La tesis principal de este artículo sostiene que hay una tercera opción: mientras los animales son pacientes morales, en lugar de agentes morales, pueden ser también sujetos morales, donde: X es un sujeto moral si y solamente si X (...) está, por lo menos algunas veces, motivado a actuar por consideraciones morales. Mediante una serie de argumentos, el artículo trata de mostrar que no hay obstáculo lógico o conceptual alguno que nos impida pensar en los animales como motivados por consideraciones morales, específicamente por emociones con un contenido moral identificable.

This paper describes and defends the view that minimal chemical life essentially involves the chemical integration of three chemical functionalities: containment, metabolism, and program (Rasmussen et al. in Protocells: bridging nonliving and living matter, 2009a ). This view is illustrated and explained with the help of CMP and Rasmussen diagrams (Rasmussen et al. In: Rasmussen et al. (eds.) in Protocells: bridging nonliving and living matter, 71–100, 2009b ), both of which represent the key chemical functional dependencies among containment, metabolism, and (...) program. The CMP model of minimal chemical life gains some support from the broad view of life as open-ended evolution, which I have defended elsewhere (Bedau in The philosophy of artificial life, 1996 ; Bedau in Artificial Life, 4:125–140, 1998 ). Further support comes from the natural way the CMP model resolves the puzzle about whether life is a matter of degree. (shrink)

It was a happy surprise when, overcoming partisan divisions and interest‐group lobbying, Congress enacted the No Surprises Act, which bans unfair out‐of‐network “balance billing.” Although this is only a modest legislative victory, key efforts by the health policy community made a real difference in a time of legislative gridlock.

The Companion begins with a section-by-section overview of Being and Time and a chapter reviewing the genesis of this seminal work. The final chapter situates Being and Time in the context of Heidegger's later work.

Hubert L. Dreyfus's engagement with other thinkers has always been driven by his desire to understand certain basic questions about ourselves and our world. The philosophers on whom his teaching and research have focused are those whose work seems to him to make a difference to the world. The essays in this volume reflect this desire to "make a difference"--not just in the world of academic philosophy, but in the broader world.Dreyfus has helped to create a culture of reflection--of questioning (...) the deep premises that inform and shape work in artificial intelligence and cognitive science. He has also been the primary introducer and interpreter of Martin Heidegger's work to the world of information technology. The essays in this volume represent the fruitful application of deep philosophical analysis to the concerns of our modern technological world.The sections are Coping and Intentionality; Computers and Cognitive Science; and "Applied Heidegger." In addition to cognitive science and artificial intelligence, topics include everyday skills, religion, business practices, and medical care. The book concludes with Dreyfus's responses to the essays.Contributors : Daniel Andler, Patricia Benner, Albert Borgmann, Harry Collins, George Downing, Fernando Flores, Sean Kelly, Joseph Rouse, Theodore R.

Professor Weil’s thesis seems largely correct with respect to the United States, whose law on religious establishment I regularly teach. Funding is central to American debates over religious establishment. The fight over religious establishments in Virginia, which inspired both James Madison’s “Memorial and Remonstrance against Religious Assessments” and Thomas Jefferson’s “An Act for Establishing Religious Freedom,” was over whether persons could be forced to pay taxes to support religious instruction. Financial concerns were at the root of church-state debates in the (...) nineteenth century, when Protestants repeatedly rebuffed Catholics who wanted funding for Catholic private schools. Many state constitutions still have what are known as mini-Blaine Amendments that forbid public funding for religious institutions. Whether proponents of a strong separation between church and state in the United States are fighting the same battles as proponents of a strong separation of church and state in France is nevertheless problematic. The French revolutionaries had to subordinate a reactionary church. The American revolutionaries merely had to negotiate peace treaties among the different sects that supported the Declaration of Independence. Separation of church and state in the United States is best conceptualized as a division of labor among liberal institutions rather than a means for purging anti-liberal religion from the liberal public sphere.

Prompted by the development of the Theory of Challenge and Threat States in Athletes (Jones et al, 2009), recent years has witnessed a considerable increase in research examining challenge and threat in sport. This manuscript provides a critical review of the literature examining challenge and threat in sport, tracing its historical development and some of the current empirical ambiguities. In an attempt to reconcile some of these ambiguities, and utilising neurobiological evidence associated with approach- and avoidance-motivation (cf. Elliot & Covington, (...) 2001), this paper draws upon the Evaluative Space Model (ESM: Cacioppo et al., 1997) and considers the implications for understanding challenge and threat in sport. For example, rather than see challenge and threat as opposite ends of a single bipolar continuum, the ESM implies that individuals could be (1) challenged, (2) threatened, (3) challenged and threatened, or (4) neither challenged or threatened by a particular stimulus. From this perspective it could be argued that the appraisal of some sport situations as both challenging and threatening could be advantageous, whereas the current literature seems to imply that the appraisal of stress as a threat is maladaptive for performance. In drawing upon the ESM, we outline the Evaluative Space Approach to Challenge and Threat and provide several testable hypotheses for advancing understanding of challenge and threat (in sport). We also outline a number of cardiovascular and experiential measures that can be used to examine these hypotheses. In sum, this paper provides a significant theoretical, empirical and practical contribution to our understanding of challenge and threat (in sport). (shrink)

S. Kierkegaard argued that our highest task as humans is to realize an “intensified” or “developed” form of subjectivity—his name for self-responsible agency. A self-responsible agent is not only responsible for her actions. She also bears responsibility for the individual that she is. In this paper, I review Kierkegaard’s account of the role that our capacity for reflective self-evaluation plays in making us responsible for ourselves. It is in the exercise of this capacity that we can go from being subjective (...) in a degraded sense—merely being an idiosyncratic jumble of accidental and arbitrary attitudes and affects—to being a subject in the ideal or eminent sense. The latter requires the exercise of my capacity for reflective self-evaluation, since it involves recognizing, identifying with, and reinforcing those aspects of my overall make-up that allow me to express successfully a coherent way of being in the world. Kierkegaard argues that taking immortality seriously is one way to achieve the right kind of reflective stance on one’s own character or personality. Thus, Kierkegaard argues that immortality as a theoretical posit can contribute to one’s effort to own or assume responsibility for being the person one is. (shrink)

Artificial life uses computer models to study the essential nature of the characteristic processes of complex adaptive systems proceses such as self-organization, adaptation, and evolution. Work in the field is guided by the working hypothesis that simple computer models can capture the essential nature of these processes. This hypothesis is illustrated by recent results with a simple population of computational agents whose sensorimotor functionality undergo open-ended adaptive evolution. These might illuminate three aspects of complex adaptive systems in general: punctuated equilibrium (...) dynamics of diversity, a transition separating genetic order and disorder, and a law of adaptive evolutionary activity.

Over the history of the study of visual perception there has been great success at discovering countless visual illusions. There has been less success in organizing the overwhelming variety of illusions into empirical generalizations (much less explaining them all via a unifying theory). Here, this article shows that it is possible to systematically organize more than 50 kinds of illusion into a 7 × 4 matrix of 28 classes. In particular, this article demonstrates that (1) smaller sizes, (2) slower speeds, (...) (3) greater luminance contrast, (4) farther distance, (5) lower eccentricity, (6) greater proximity to the vanishing point, and (7) greater proximity to the focus of expansion all tend to have similar perceptual effects, namely, to (A) increase perceived size, (B) increase perceived speed, (C) decrease perceived luminance contrast, and (D) decrease perceived distance. The detection of these empirical regularities was motivated by a hypothesis, called “perceiving the present,” that the visual system possesses mechanisms for compensating neural delay during forward motion. This article shows how this hypothesis predicts the empirical regularity. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Journal of Aesthetic Education 38.2 (2004) 20-37 [Access article in PDF] Aesthetic Teaching Mark A. Pike I think aesthetic teaching is the highest of all teaching because it deals with life in its highest complexity. But if it ceases to be purely aesthetic — if it lapses anywhere from the picture to the diagram — it becomes the most offensive of all teaching.1George Eliot asserts that "the (...) highest of all teaching" which "deals with life in its highest complexity" is essentially aesthetic in character for it has features of the "picture" or work of art rather than the more straightforwardly instructional "diagram." Yet, George Eliot not only ascribes greatest worth to teaching that is aesthetic but considers teaching that is merely diagrammatic to be "the most offensive of all teaching." Evidently, there are similarities between pictures and diagrams but essential features present in the former are conspicuously absent from the latter. The current obsession with effectiveness in teaching and repeated attempts to reduce that which should be aesthetic and inspired to the wholly rational, diagrammatic and instrumental make George Eliot's views remarkably pertinent. Consequently, features of aesthetic teaching will be explored in this essay. In doing so it will be suggested that Martin Heidegger's ontology (theory of existence) offers a philosophical foundation for conceiving teaching in the arts as a form of engagement with students which is unreservedly aesthetic in character. As such, Heidegger provides us with a valuable position from which to counter forces that militate against the aesthetic in our schools and also provokes us to eschew all that is diagrammatic in our approach to that which is rightly aesthetic. Teaching: Drawing the Diagram or Painting the Picture? Teaching is currently being construed, in both the United Kingdom and the United States, as a technology with which to get something done or as a [End Page 20] vehicle which "delivers" a subject in an efficient or effective manner, or even as a science where the analytical approach is the method for problem solving. Even as I write, I find myself part of a proposed "delivery team" for literature education. It appears that this is the sort of language policy makers in a rational economy like to hear. Any dissenting voices, those subscribing to a view of teaching as an art itself, are considered dangerous as they jeopardize progress in our brave new world. For example, in their introduction to Effective Teaching — Evidence and Practice, Daniel Muijs and David Reynolds articulate the view that construing teaching as an art rather than a technology may be responsible for the lack of excellent teachers in our schools.2 In marked contrast to George Eliot, they suggest "the view that teaching is an 'art,' not a science" results in attention being devoted to "personal factors and qualities" which are "often idiosyncratic and difficult to influence by educational policies."3 Further, they suggest that the placing of education within the humanities tradition — is clearly wrong and probably condemns societies where it is prevalent to having only those small number of excellent teachers who inherit the "art," rather than the larger number who could acquire the applied science of a teaching methodology.4It is difficult to conceive of a position further removed from George Eliot's ideal of aesthetic teaching. There are, of course, a number of problems with reducing teaching to a technology, or an applied science, as Muijs and Reynolds prefer to call it. Such argument betrays the assumption that the world can be known in a rational, analytical and scientific way. The concomitant of this view is the misguided belief that teaching about such a world can be precisely planned, implemented and assessed. Elliot Eisner is surely more accurate when he explains that "teaching is a form of human action in which many of the ends achieved are emergent" and that these ends are often "found in the course of interaction with students rather than preconceived."5 Clearly, allowing "for the creation of ends in process" necessitates "a model of teaching akin to other arts."6 This is more...

In this paper I hope to demonstrate that, despite dramatic differences in approach, Analytic and Continental philosophers can be brought into a productive dialogue with one another on topics central to the philosophical agenda of both traditions. Their differences tend to obscure the fact that both traditions have as a fundamental project the critique of past accounts of language, intentionality, and mind. Moreover, writers within the two traditions are frequently in considerable agreement about the failings of past accounts. Where they (...) tend to differ is in the sorts of positive accounts they give. By exploring the important areas of disagreement against the background of agreement, however, it is possible to gain insights unavailable to those rooted in a single tradition. (shrink)

Contemporary arguments for scientific realism are typically based on some form of inference to the best explanation. Sometimes such arguments concern the methods of science: given the success of scientific methodology, realism offers the best explanation of this success. Sometimes such arguments concern the content of scientific theories: given observed regularities in nature, explanations must be given of those regularities; the best such explanations will be realist. One forceful explanationist argument about the content of science can be based on Hans (...) Reichenbach’s Principle of the Common Cause. Roughly, CC says that whenever an enduring correlation between two events is observed, there must be some preceding event which is the common cause of the two, and is the explanation for the correlation. Rigid adherence to this demand for a common cause, however, supposedly goes beyond the instrumentalist explanatory resources available to the antirealist, and hence CC is taken to be a sufficient condition for realism. Further, one might claim that any argument that realism has greater explanatory power than antirealism depends either explicitly or implicitly on CC, and hence CC is also a necessary condition for realism.

The Rationality Principle says that people act adequately to their situation, but does not specify how they must act in order to do so. Situational Analysis uses the Rationality Principle, together with a model of the social situation, to explain actions in the past. Unlike Rational Choice Theory, Situational Analysis does not try to predict or influence actions in the future. Popper regarded the Rationality Principle as false, but thought that we should use it nonetheless. This poses a problem for (...) understanding his views about conjecture and refutation. Popper, however, thought that all scientific models are false, and that whether or not we should reject a model depends on the problem that we are trying to solve. (shrink)

Not since the civil rights era has enacted national legislation been fought so fiercely as the Patient Protection and Affordable Care Act. Political, ideological, and social forces have mobilized to undermine the ACA at numerous fronts, including the Supreme Court, Congress, state governments, and the court of public opinion.

Opponents of the Affordable Care Act have attempted to topple it in court by challenging the legality of two of its three legs. Three years ago, in NFIB v. Sibelius, Chief Justice Roberts narrowly upheld the constitutionality of the individual mandate, in a 5-to-4 decision that characterized the mandate as an optional tax rather than as a regulatory command. This year, on June 25, the health policy community exhaled a giant sigh of relief when the Supreme Court upheld the subsidy (...) leg of the ACA structure. In King v. Burwell, Justice Roberts again wrote the majority opinion, ruling as a matter of statutory interpretation that subsidies for insurance premiums are available not just through state-based exchanges but also through the federal exchange.

Many academics and world leaders have declared that there is a moral imperative to address climate change. But such claims often fall on deaf ears because the nature of the threat posed by global warming lacks many of the features of a paradigmatic moral transgression [Jamieson, Dale. 2007. The moral and political challenges of climate change. Working Paper, New York University, New York]. This paper explores these psychological obstacles to moral engagement about climate change. I argue that the temporal and (...) psychosocial distance of the threat of global warming undermines the kind of affective response that motivates moral concern. I conclude by suggesting that images focusing more on the personal and short-term consequences of global warming will generate stronger moral reactions. (shrink)

Personal identity is critical to provider–patient interactions. Patients and doctors tend to self-select, ideally forming therapeutic units that maximise the patients' benefit. Recently, however, ‘reality’ has changed. The internet and virtual worlds such as Second Life allow models of identity and provider–patient interactions that go beyond the limits of mainstream personal identity. In this paper some of the ethical implications of virtual patient–provider interactions, especially those that have to do with personal identity, are explored.
