Evidence suggests that research participants often fail to recall much of the information provided during the informed consent process. This study was conducted to determine the proportion of consent information recalled by drug court participants following a structured informed consent procedure and the neuropsychological factors that were related to recall. Eighty-five participants completed a standard informed consent procedure to participate in an ongoing research study, followed by a 17-item consent quiz and a brief neuropsychological battery 2 weeks later. Participants performed (...) within the normal range on most of the neuropsychological measures, although roughly one third showed deficits on measures of executive functioning. Participants failed to recall over 65% of the consent information within 2 weeks of entering the study, and their recall was significantly correlated with verbal IQ, drug problem severity, reading ability, memory, and attention. These factors may be useful in determining whether research participants require enhanced consent procedures. (shrink)
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.

From Kierkegaard’s famous polemic against Hegel’s system, and Marx’s rejection of the “mysticism” of reason, to Heidegger’s claim that Hegel completes the tradition of western metaphysics, and contemporary critics’ identification of Hegel as the authoritative spokesman — the “Master” — for the principles of unity and identity, a standard view has governed interpretations and evaluations of Hegel’s philosophy. Though familiarity with the positions just cited reveals considerable disparity, one does not need an especially discerning eye to recognize the common features (...) of the figures drawn. Hegel is, in all of them, the philosopher of the Absolute, the proponent of metaphysics without equal in the modern world. (shrink)
Clarke proposes a conception of philosophy that provides an alternative to the reductions of materialism and the search for normative principles. Philosophy's proper role is to describe similarities and differences among differing levels of language, specifically the familiar level of discourse within an ordinary language shared by all and the specialized discourses of social institutions such as science, law, and the arts. By constructing a logical framework in which these comparisons and contrasts can be made, philosophy performs the indispensable role (...) of promoting the integration of disparate elements of our culture.

_Real Essentialism_ presents a comprehensive defence of neo-Aristotelian essentialism. Do objects have essences? Must they be the kinds of things they are in spite of the changes they undergo? Can we know what things are really like – can we define and classify reality? Many, if not most, philosophers doubt this, influenced by centuries of empiricism, and by the anti-essentialism of Wittgenstein, Quine, Popper, and other thinkers. _Real Essentialism_ reinvigorates the tradition of realist, essentialist metaphysics, defending the reality and knowability (...) of essence, the possibility of objective, immutable definition, and its relevance to contemporary scientific and metaphysical issues such as whether essence transcends physics and chemistry, the essence of life, the nature of biological species, and the nature of the person.

Although biologists and philosophers of science generally agree that genes cannot determine the forms of biological and psychological traits, students, journalists, politicians, and other members of the general public nonetheless continue to embrace genetic determinism. This article identifies some of the concerns typically raised by individuals when they first encounter the systems perspective that biologists and philosophers of science now favor over genetic determinism, and uses arguments informed by that perspective to address those concerns. No definitive statements can yet be (...) made about why genetic determinism has proven so resilient in the face of empirical evidence pointing up its deficiencies, but conveying the essential interdependence of 'nature' and 'nurture' to the general public will likely require deployment of the arguments that systems theorists ordinarily use to reject genetic determinism. In addition, the elaboration of new metaphors that focus attention on the dynamic nature of trait construction will likely prove valuable, because re-conceptualizing notions like 'genes' and 'nature' will probably be one of the most effective ways to help students and the general public abandon the genetic determinism that biologists now recognize as indefensible.

We examine two different descriptions of the behavioral functions of the hippocampal system. One emphasizes spatially organized behaviors, especially those using cognitive maps. The other emphasizes memory, particularly working memory, a short-term memory that requires iexible stimulus-response associations and is highly susceptible to interference. The predictive value of the spatial and memory descriptions were evaluated by testing rats with damage to the hippocampal system in a series of experiments, independently manipulating the spatial and memory characteristics of a behavioral task. No (...) dissociations were found when the spatial characteristics of the stimuli to be remembered were changed; lesions produced a similar deficit in both spatial and nonspatial test procedures, indicating that the hippocampus was similarly involved regardless of the spatial nature of the task. In contrast, a marked dissociation was found when the memory requirements were altered. Rats with lesions were able to perform accurately in tasks that could be solved exclusively on the basis of reference memory. They performed at chance levels and showed no signs of recovery even with extensive postoperative training in tasks that required working memory. In one experiment all the characteristics of the reference memory and working memory procedures were identical except the type of memory required. Consequently, the behavioral dissociation cannot be explained by differences in attention, motivation, response inhibition, or the type of stimuli to be remembered. As a result of these experiments we propose that the hippocampus is selectively involved in behaviors that require working memory, irrespective of the type of material that is to be processed by that memory.

Although Mealey's account provides several interesting hypotheses, her integration across disparate samples renders the value of her explanation for psychopathy ambiguous. Recent evidence on Psychopathy Checklist-identified samples (Hare, 1991) suggests primary emotional and cognitive deficits inconsistent with her model. Whereas high-anxious psychopaths display interpersonal deficits consistent with Mealey's hypotheses, low-anxious psychopaths' deficits appear more sensitive to situational parameters than predicted.
As part of the South Carolina Law Review's symposium on the Roberts Court and Equal Protection, this essay looks at Justice Kennedy's sex discrimination jurisprudence. With the new Court, it's natural to be concerned with how the two new Justices might vote in upcoming sex discrimination cases. However, in this essay, I assume what has been the case so far from Chief Justice Roberts and Justice Alito - that they are reliable votes joining Justices Scalia and Thomas on the Court's (...) more conservative wing. The Justice most people should focus on now is Justice Kennedy, the new median Justice now that Justice O'Connor has retired. This essay seeks to analyze Justice Kennedy's sex discrimination jurisprudence and draw conclusions about his thoughts on sex and gender. First, it reviews the cases involving sex discrimination that Justice Kennedy has participated in while on the Court and shows that he has been a fairly consistent vote against sex discrimination claims. Second, it analyzes Justice Kennedy's votes and opinions in sex discrimination cases and attempt to summarize his views. Finally, the essay evaluates Justice Kennedy's conceptions of gender in his opinions and votes. The essay concludes that Justice Kennedy's new role as median Justice is troubling for sex equality jurisprudence generally and constitutional sex discrimination cases specifically, as Justice Kennedy has shown a tendency, in the many cases arising in the parent/child context, to adhere to traditional and paternalistic gender roles.

As machine learning has gradually entered into ever more sectors of public and private life, there has been a growing demand for algorithmic explainability. How can we make the predictions of complex statistical models more intelligible to end users? A subdiscipline of computer science known as interpretable machine learning has emerged to address this urgent question. Numerous influential methods have been proposed, from local linear approximations to rule lists and counterfactuals. In this article, I highlight three conceptual challenges that are (...) largely overlooked by authors in this area. I argue that the vast majority of IML algorithms are plagued by ambiguity with respect to their true target; a disregard for error rates and severe testing; and an emphasis on product over process. Each point is developed at length, drawing on relevant debates in epistemology and philosophy of science. Examples and counterexamples from IML are considered, demonstrating how failure to acknowledge these problems can result in counterintuitive and potentially misleading explanations. Without greater care for the conceptual foundations of IML, future work in this area is doomed to repeat the same mistakes. (shrink)
Back cover: How is God revealed through the life of a human community? Dietrich Bonhoeffer's theological ethics begins from the claim to 'Christ existing as community', which David Robinson presents as one of several critical and politically astute variations on G.W.F. Hegel's philosophy of religion.
The distinction between the essence of an object and its properties has been obscured in contemporary discussion of essentialism. Locke held that the properties of an object are exclusively those features that ‘flow’ from its essence. Here he follows the Aristotelian theory, leaving aside Locke’s own scepticism about the knowability of essence. I defend the need to distinguish sharply between essence and properties, arguing that essence must be given by form and that properties flow from form. I give a precise (...) definition of what the term of art ‘flow’ amounts to, and apply the distinction to various kinds of taxonomic issues. (shrink)

We propose a formal framework for interpretable machine learning. Combining elements from statistical learning, causal interventionism, and decision theory, we design an idealisedexplanation gamein which players collaborate to find the best explanation(s) for a given algorithmic prediction. Through an iterative procedure of questions and answers, the players establish a three-dimensional Pareto frontier that describes the optimal trade-offs between explanatory accuracy, simplicity, and relevance. Multiple rounds are played at different levels of abstraction, allowing the players to explore overlapping causal patterns of (...) variable granularity and scope. We characterise the conditions under which such a game is almost surely guaranteed to converge on a (conditionally) optimal explanation surface in polynomial time, and highlight obstacles that will tend to prevent the players from advancing beyond certain explanatory thresholds. The game serves a descriptive and a normative function, establishing a conceptual space in which to analyse and compare existing proposals, as well as design new and improved solutions. (shrink)

Machine learning algorithms may radically improve our ability to diagnose and treat disease. For moral, legal, and scientific reasons, it is essential that doctors and patients be able to understand and explain the predictions of these models. Scalable, customisable, and ethical solutions can be achieved by working together with relevant stakeholders, including patients, data scientists, and policy makers.
Researchers and practitioners have devoted considerable attention to firms'' policies regarding discretionary disclosures. Prior studies argue that firms increase demand for their debt and equity issues and, thus, lower their cost of capital, by providing more informative disclosures. However, empirical research has generally not been able to document significant benefits from increased disclosure.This paper proposes an alternative explanation – firms disclose because it is the socially responsible thing to do. We argue that companies have incentives to engage in stakeholder management (...) by undertaking socially responsible activities and that providing extensive and informative disclosures is one such practice.We examine the relationship between firms'' disclosures and measures of social responsibility. We use ratings provided by the Council on Economic Priorities as proxies for the degree of social responsibility adopted by the sample firms. Disclosure rankings provided by the annual Association for Investment Management and Research Corporate Information Committee Reports (AIMR Reports) are used to measure disclosure level.Our results indicate that there is a positive relationship between disclosure level and corporate social responsibility. That is, firms that engage in socially responsive activities provide more informative and/or extensive disclosures than do companies that are less focused on advancing social goals. In addition, we find that socially responsible firms are more likely to provide this increased disclosure through better investor relations practices. These results support our contention that increased disclosure is a form of socially responsible behavior. (shrink)
To the extent that dualism is even taken to be a serious option in contemporary discussions of personal identity and the philosophy of mind, it is almost exclusively either Cartesian dualism or property dualism that is considered. The more traditional dualism defended by Aristotelians and Thomists, what I call hylemorphic dualism, has only received scattered attention. In this essay I set out the main lines of the hylemorphic dualist position, with particular reference to personal identity. First I argue that overemphasis (...) of the problem of consciousness has had an unhealthy effect on recent debate, claiming instead that we should emphasize the concept of form. Then I bring in the concept of identity by means of the notion of substantial form. I continue by analyzing the relation between form and matter, defending the traditional theses of prime matter and of the unicity of substantial form. I then argue for the immateriality of the substantial form of the human person, viz. the soul, from an account of the human intellect. From this follows the soul's essential independence of matter. Finally, although the soul is the immaterial bearer of personal identity, that identity is still the identity of an essentially embodied being. I explain how these ideas are to be reconciled. Footnotesa I am grateful to Stephen Braude, John Cottingham, John Haldane, David Jehle, Joel Katzav, Eduardo Ortiz, and Fred Sommers for helpful comments and discussion of a draft of this essay. I would also like to thank Ellen Paul, whose suggestions have helped greatly to improve the essay's style and content. (shrink)
This paper describes differences in two perspectives on the idea of virtue as a theoretical foundation for positive organizational ethics (POE). The virtue ethics perspective is grounded in the philosophical tradition, has classical roots, and focuses attention on virtue as a property of character. The positive social science perspective is a recent movement (e.g., positive psychology and positive organizational scholarship) that has implications for POE. The positive social science movement operationalizes virtue through an empirical lens that emphasizes virtuous behaviors. From (...) a virtue ethics perspective, a behaviorally based account of virtue is a weak theory of virtue. Observations are suggested for integrating the two perspectives. First, virtue should always be understood as an excellence and is often an optimal point between extreme dysfunctions on continuum of potential states. Second, an empirical exploration of virtue needs to account for character and context. Finally, the properties of organization-level virtue need to be further specified and explored. Implications and directions for future research are discussed. (shrink)
This essay challenges the portrayal of philosophical idealism as sinful ‘confinement in the self’, arguing that this obscures a relationship between Hegel and Bonhoeffer characterised by variation rather than contradiction. I first trace a limited congeniality between their respective critiques of the ‘beautiful soul’ and the ‘privately virtuous’, showing how both thinkers resist moral isolation through the call to confession. Second, I follow their attempts to overcome an oppositional logic between such social exchange and divine agency, rooted in the syntax (...) of Hegel’s phrase ‘God existing as community’. This provides sharper focus to Bonhoeffer’s variations, changing the subject from God to Christ and the attendant act from reciprocal confession to intercessory prayer. Rather than merely defensive revision, I argue that this reveals an agile Christology which can sustain an ethical posture of ‘being for others’ through the withheld confession and broken trust typical of a communion of sinners.
