In the United States, approximately 2.53 million people sustain a concussion each year. Relative to adults, youth show greater cognitive deficits following concussion and a longer recovery. An accurate and reliable imaging method is needed to determine injury severity and symptom resolution. The primary objective of this study was to characterize concussions with diffusion tensor imaging. This was performed through a normative Z-scoring analysis of DTI metrics, fractional anisotropy, axial diffusivity, and radial diffusivity, to quantify patient-specific injuries and identify commonly (...) damaged brain regions in paediatric concussion patients relative to healthy controls. It was hypothesized that personalizing the detection analysis through normative Z-scoring would provide an understanding of trauma-induced microstructural damage. Concussion patients were volunteers recruited from the Emergency Department of the McMaster Children’s Hospital with a recent concussion, 9 males and 17 females, mean age 14.22 ± 2.64, while healthy paediatric brain DTI datasets were obtained from an MRI data repository. Significant abnormalities were commonly found in the longitudinal fasciculus, fronto-occipital fasciculus, and corticospinal tract, while unique abnormalities were localized in a number of other areas reflecting the individuality of each child’s injury. Total injury burden, determined by the number of regions containing outliers per DTI metric per patient, was used as the metric to quantify the overall injury severity of each patient. The primary outcome of this analysis found that younger patients experienced a significantly greater injury burden when measured using fractional anisotropy. These results show that DTI was able to detect microstructural changes caused by concussion, on a per-person basis, and has the potential to be a useful tool for improving diagnostic accuracy and prognosis of a concussion.

A medical student's ability to present a case history is a critical skill that is difficult to teach. Case histories presented without theatrical engagement may fail to catch the attention of their intended recipients. More engaging presentations incorporate ‘stage presence’, eye contact, vocal inflection, interesting detail and succinct, well organised performances. They convey stories effectively without wasting time. To address the didactic challenge for instructing future doctors in how to ‘act’, the Mayo Medical School and The Mayo Clinic Center for (...) Humanities in Medicine partnered with the Guthrie Theater to pilot the programme ‘Telling the Patient's Story’. Guthrie teaching artists taught storytelling skills to medical students through improvisation, writing, movement and acting exercises. Mayo Clinic doctors participated and provided students with feedback on presentations and stories from their own experiences in patient care. The course's primary objective was to build students' confidence and expertise in storytelling. These skills were then applied to presenting cases and communicating with patients in a fresher, more engaging way. This paper outlines the instructional activities as aligned with course objectives. Progress was tracked by comparing pre-course and post-course surveys from the seven participating students. All agreed that the theatrical techniques were effective teaching methods. Moreover, this project can serve as an innovative model for how arts and humanities professionals can be incorporated for teaching and professional development initiatives at all levels of medical education.

Timothy Fuller has here performed the valuable task of bringing together Michael Oakeshott's most important essays on education. Fuller also includes a helpful introduction which distinguishes Oakeshott's views from those of Allan Bloom and E. D. Hirsch, and which situates Oakeshott's reflections in the context of his basic philosophical commitments. These essays are interesting and important not only in their own right, but also for their illumination of themes present in Oakeshott's longer works.

A stunning exploration of the relation between desire and psychopathology, The Death of Desireis a unique synthesis of the work of Laing, Freud, Nietzsche, and Heidegger that renders their often difficult concepts brilliantly accessible to and usable by psychotherapists of all persuasions. In bridging a critical gap between phenomenology and psychoanalysis, M. Guy Thompson, one of the leading existential psychoanalysts of our time, firmly re-situates the unconscious - what Freud called "the lost continent of repressed desires" - in phenomenology. In (...) so doing, he provides us with the richest, most compelling phenomenological treatment of the unconscious to date and also makes Freud's theory of the unconscious newly comprehensible. In this revised and updated second edition to the original published in 1985, M. Guy Thompson takes us inside his soul-searching seven-year apprenticeship with radical psychiatrist R. D. Laing and his cohorts as it unfolded in counterculture London of the 1970s. This rite de passage culminates with a four-year sojourn inside one of Laing's post-Kingsley Hall asylums, where Laing's unorthodox conception of treatment dispenses with conventional boundaries between "doctor" and "patient." In this unprecedented exploration, Thompson reveals the secret to Laing's astonishing alternative to the conventional psychiatric and psychoanalytic treatment schemes. Movingly written and deeply personal, Thompson shows why the very concept of "mental illness" is a misnomer and why sanity and madness should be understood instead as inherently puzzling stratagems that we devise in order to protect ourselves from intolerable mental anguish. The Death of Desireoffers a provocative and challenging reappraisal of depth psychotherapy from an existential perspective that will be of interest to psychoanalysts, psychotherapists, philosophers, social scientists, and students of the human condition.

The life–mind continuity thesis is difficult to study, especially because the relation between life and mind is not yet fully understood, and given that there is still no consensus view neither on what qualifies as life nor on what defines mind. Rather than taking up the much more difficult task of addressing the many different ways of explaining how life relates to mind, and vice versa, this paper considers two influential accounts addressing how best to understand the life–mind continuity thesis: (...) first, the theory of autopoiesis (AT) developed in biology and in enactivist theories of mind; and second, the recently formulated free energy principle in theoretical neurobiology, with roots in thermodynamics and statistical physics. This paper advances two claims. The first is that the free energy principle (FEP) should be preferred to the theory of AT, as classically formulated. The second is that the FEP and the recently formulated framework of autopoietic enactivism can be shown to be genuinely continuous on a number of central issues, thus raising the possibility of a joint venture when it comes to answering the life–mind continuity thesis.

We develop a truism of commonsense psychology that perception and action constitute the boundaries of the mind. We do so however not on the basis of commonsense psychology, but by using the notion of a Markov blanket originally employed to describe the topological properties of causal networks. We employ the Markov blanket formalism to propose precise criteria for demarcating the boundaries of the mind that unlike other rival candidates for “marks of the cognitive” avoids begging the question in the extended (...) mind debate. Our criteria imply that the boundary of the mind is nested and multiscale sometimes extending beyond the individual agent to incorporate items located in the environment. Chalmers has used commonsense psychology to develop what he sees as the most serious challenge to the view that minds sometimes extend into the world. He has argued that perception and action should be thought of as interfaces that separate minds from their surrounding environment. In a series of recent papers Hohwy has defended a similar claim using the Markov blanket formalism. We use the Markov blanket formalism to show how both of their objections to the extended mind fail.

Ethical decision making measures are widely applied as the principal dependent variable used in studies of research integrity. However, evidence bearing on the internal and external validity of these measures is not available. In this study, ethical decision making measures were administered to 102 graduate students in the biological, health, and social sciences, along with measures examining exposure to ethical breaches and the severity of punishments recommended. The ethical decision making measure was found to be related to exposure to ethical (...) events and the severity of punishments awarded. The implications of these findings for the application of ethical decision making measures are discussed. (shrink)

Recounts the works of Immanuel Velikovsky and the controversies surrounding it, discussing his influence on the counterculture and debates with such luminaries as Carl Sagan.

It is commonly held that early career experiences influence ethical behavior. One way early career experiences might operate is to influence the decisions people make when presented with problems that raise ethical concerns. To test this proposition, 102 first-year doctoral students were asked to complete a series of measures examining ethical decision making along with a series of measures examining environmental experiences and climate perceptions. Factoring of the environmental measure yielded five dimensions: professional leadership, poor coping, lack of rewards, limited (...) competitive pressure, and poor career direction. Factoring of the climate inventory yielded four dimensions: equity, interpersonal conflict, occupational engagement, and work commitment. When these dimensions were used to predict performance on the ethical decision-making task, it was found that the environmental dimensions were better predictors than the climate dimensions. The implications of these findings for research on ethical conduct are discussed. (shrink)

This paper explores analyzing criminal responsibility from the Humean position that blame is for character traits. If untoward acts indicate undesirable character traits, then the agent is blameworthy; if they do not, then the actor is not blameworthy — he has an excuse. A distinctive feature of this approach is that that voluntariness of acts is irrelevant to determining blameworthiness.This analysis is then applied to a variety of issues in criminal law. Mens supports inferences to character traits, and the Humean (...) approach provides a reason for rejeting strict criminal liability. The Humean approach also helps resolve a number of issues about attempts, such as punishment for impossible attempts and the defense of abandonment. It also supports the broad outlines of the defense of mistake and provides a third alternative in the Wooton-Hart debate over punishment and treatment. (shrink)

Individuals of some animal species have been taught simple versions of human language despite their natural communication systems failing to rise to the level of a simple language. How is it, then, that some animals can master a version of language, yet none of them deploy this capacity in their own communication system? I first examine the key design features that are often used to evaluate language-like properties of natural animal communication systems. I then consider one candidate animal system, bird (...) song, because it has several of the key design features or their precursors, including social learning and cultural transmission of their vocal signals. I conclude that although bird song communication is nuanced and complex, and has the acoustic potential for productivity, it is not productive – it cannot be used to say many different things. Finally, I discuss the debate over whether animal communication should be viewed as a cooperative information transmission process, as we typically view human language, or as a competitive process where signaler and receiver vie for control. The debate points to a necessary condition for the evolution of a simple language that has generally been overlooked: the degree of to which the interests of the signaler and receiver align. While strong cognitive and signal production mechanisms are necessary pre-adaptations for a simple language, they are not sufficient. Also necessary is the existence of identical or near-identical interests of signaler and receiver and a socio-ecology that requires high-level cooperation across a range of contexts. In the case of our hominid ancestors, these contexts included hunting, gathering, child care and, perhaps, warfare. I argue that the key condition for the evolution of human language was the extreme interdependency that existed among unrelated individuals in the hunter-gatherer societies of our hominid ancestors. This extreme interdependency produced multiple prosocial adaptations for effective intragroup cooperation, which in partnership with advanced cognitive abilities, set the stage for the evolution of language.

John McDowell rejects the idea that non-conceptual content can rationally justify empirical claims—a task for which it is ill-fitted by its non-conceptual nature. This paper considers three possible objections to his views: he cannot distinguish empty conception from the perceptual experience of an object; perceptual discrimination outstrips the capacity of concepts to keep pace; and experience of the empirical world is more extensive than the conceptual focusing within it. While endorsing McDowell’s rejection of what he means by non-conceptual content, and (...) appreciating his insight into the experiential synthesis of intuition and conception (in particular, its role in grasping objects), I will argue that Edmund Husserl presents an even more comprehensive account of perceptual experience that explains how we experience the contribution of receptivity and sensibility and how they cooperate in perceptual discrimination. Further, it reveals “horizons”—a unique kind of contents, surplus content (rather than independent non-conceptual content)—beyond the synthesis of intuitive and conceptual contents through which objects are grasped. Such horizons play a constitutive role, making experience with its conceptual dimensions and justificatory potential possible; they in no way function like a bare given that is to fulfill some independent justificatory role. Whereas McDowell focuses on how experience does not take place in isolation from the exercise of conceptual capacities, Husserl complements his view by situating experience in a more encompassing whole and by elucidating the surplus-horizons that exceed the conceptual content of experience; play an inseparable, constitutive role within it; and indicate the limits of conceptual comprehension.

This paper examines the relationship between perceiving and imagining on the basis of predictive processing models in neuroscience. Contrary to the received view in philosophy of mind, which holds that perceiving and imagining are essentially distinct, these models depict perceiving and imagining as deeply unified and overlapping. It is argued that there are two mutually exclusive implications of taking perception and imagination to be fundamentally unified. The view defended is what I dub the ecological–enactive view given that it does not (...) succumb to internalism about the mind-world relation, and allows one to keep a version of the received view in play.

Systematic errors In performance are an important aspect of human behavior that have not received adequate explanation. One such systematic error is termed postcompletion error; a typical example is leaving one's card In the automatic teller after withdrawing cash. This type of error seems to occur when people have an extra step to perform in a procedure after the main goal has been satisfied. The fact that people frequently make this type of error, but do not make this error every (...) time, may best be explained by considering the working memory load at the time the step is to be performed: The error is made when the load on working memory is high, but will not be made when the load is low. A model of performance In the task was constructed using Just and Carpenter's (1992) CAPS that predicted that high working memory load should be associated with postcompletion errors. Two experiments confirmed that such errors can be produced in a laboratory as well as a naturalistic setting, and that the conditions under which the CAPS model makes the error are consistent with the conditions under which the errors occur in the laboratory.

Using Canada as a case study, this article argues that regulating biotechnology and nanotechnology is made unnecessarily complex and inherently unstable because of a failure to consult the public early and of-ten enough. Furthermore, it is argued that future regulators (and promoters) of nanotechnology may learn valuable lessons from the mistakes made in regulating biotechnology.

This paper is a nontechnical exposition of the author's view that mathematics is a science of patterns and that mathematical objects are positions in patterns. the new elements in this paper are epistemological, i.e., first steps towards a postulational theory of the genesis of our knowledge of patterns.

Within three of the most well-known contemporary approaches to argumentation, the notions of solo argumentation and arguing with one’s self are given little attention and are typically argued to be able to be subsumed within the dialectical aspects of the approach being propounded. Challenging these claims, this paper has two main aims. The first is to argue that while dialogical argumentation may be most common, there exists individual dialectical argumentation, which is not so easily subsumed within these theories. Second, in (...) order characterize this type of argumentation the paper also offers distinctions between the interrelated notions of dialectical, dialogical, and quasi-dialogical, reasoning and argumentation, within an individual or between multiple participants, which I hope provide useful precision for the field.

I compare the tasks that Noam Chomsky and W. V. Quine assign the grammarian and point out that in many cases where Chomsky sees a question of fact Quine sees only a question of convenience. I argue that these differences are attributable, at least in part, to a difference in view concerning the data. Chomsky relies mostly on a speaker's reports of his linguistic intuitions. Quine finds this source methodologically moot. I develop a series of arguments that draw on Quine's (...) theory of radical translation to defend Quine's doubts. (shrink)

This paper offers insights into the nature and design of critical questions as they are found in argumentation schemes. In the first part of the paper, I address some general concerns regarding their purpose and formulation. These include a discussion of their evaluative function, their relationship with the patterns of reasoning they accompany, as well as the differing formulations of critical questions currently on offer. I argue that the purpose of critical questions for humans ought to be to provide the (...) means for a scalar evaluation of the reasoning at hand. To do so, critical questions should be closely paired with individual premises in the accompanying pattern of reasoning and be open-ended. Doing so allows the roles of raising considerations relevant for the reasoning and scrutinizing those considerations to be clearly distinguished. In the second part of the paper, I offer a positive methodological proposal for the construction of questions and premises that aims at overcoming a number of the individual and systematic shortcomings of extant question styles. The paper concludes by arguing that the newly proposed approach is both normatively strong and practically useful for argumentation in context. (shrink)

This paper takes three distinct passes through the history of Machine Translation (MT) in the Soviet Union, which is typically understood as concentrating in a single boom period that lasted from roughly 1955 to 1965. In both the Soviet Union and the United States—in explicit competition with each other—there was a tremendous wave of investment in adapting computers to nonnumerical tasks that has only recently drawn the attention of historians, primarily focusing on the American example. The Soviet Union, however, quickly (...) came to assume prominence in the field both in terms of scale and diversity of approaches. At the same moment, Soviet linguists excavated a forgotten precursor, P. P. Smirnov-Troianskii, who had designed a translating machine in the early 1930s. Juxtaposing the multiple contexts in which Smirnov-Troianskii’s machine was reconceptualized and reappropriated for various ends, the article demonstrates the fundamental embodying of the algorithm in the early days of MT and also how the proliferation of narratives about Soviet MT exposes fault lines in contemporary historiography.
