There are competing ethical concerns when it comes to designing any clinical research study. Clinical trials of possible treatments for Ebola virus are no exception. If anything, the competing ethical concerns are exacerbated in trying to find answers to a deadly, rapidly spreading, infectious disease. The primary goal of current research is to identify experimental therapies that can cure Ebola or cure it with reasonable probability in infected individuals. Pursuit of that goal must be methodologically sound, practical and consistent with (...) prevailing norms governing human subjects research. Some maintain that only randomized controlled trials with a placebo or standard-of-care arm can meet these conditions. We maintain that there are alternative trial designs that can do so as well and that sometimes these are preferable to RCTs. (shrink)

The cognitive and behavioral functions of the frontal lobes have been of great interest to neuroscientists, neurologists, psychologists and psychiatrists. Recent technical advances have made it possible to trace their neuroanatomical connections more precisely and to conduct evoked potential and neuroimaging studies in patients. This book presents a broad and authoritative synthesis of research progress in this field. It encompasses neuroanatomical studies; experiments involving temporal organization and working memory tasks in non-human primates; clinical studies of patients following frontal lobe excisions (...) for intractable epilepsy; metabolic imaging in schizophrenia and affective disorder; neurobehavioral studies of patients with dementia, frontal lobe tumors, and head injuries; magnetic resonance imaging methods for studying human frontal lobe anatomy; theoretical approaches to describing frontal lobe functions; and rehabilitation of patients with frontal lobe damage including their core problem of diminished awareness. Written by a distinguished group of neuroscientists, psychologists and clinicians, Frontal Lobe Function and Dysfunction provides the best current source of information on this region of the brain and its role in cognition, behavior and clinical disorders.

Measurements involving spin-1/2 meters which result in the simultaneous measurement of spin components are described. The spin analoge of the Arthur-Kelly experiment is contrasted with a simultaneous measurement which interacts with the system. Naimark extensions are constructed and Bloch state projection properties are discussed for each case. The theory is extended to squeezed angular momentum measurement.

In the realm of corporate leadership and organisational theory, the work of the German philosopher, Martin Heidegger, has received little if any attention from scholars and practitioners alike. We argue in this paper that Heidegger’s work has an important message to convey with regard to the ability and perhaps the obligation of leaders to enable the ‘releasement’ and ‘opening up’ of the members of an organisational community to their ‘authentic possibilities’ within the realm of the work environment. We apply the (...) Heideggerian concepts of calculative and reflective thinking, as well as his philosophy of ‘being’ to the role of authentic leaders and their leadership possibilities. And we distinguish this approach to leadership from that which we identify as ‘inauthentic’ in which both leaders and members of organisations are alienated from their possibilities. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Arthur A. Krentz DRAMATIC FORM AND PHILOSOPHICAL CONTENT IN PLATO'S DIALOGUES AN intriguing innovation in the history of philosophical discourse is Plato's employment ofdramatic dialogues as his deliberately chosen means ofcommunication. Throughout the history of philosophy scant attention has been focused on this feature of Plato's works. Recently, however, some students of Plato's writings contend that it is crucial for interpreters to give careful attention to the dialogue (...) form in order to reach an essential understanding of the philosophical content. Thus WernerJaeger, commenting in 1934 on the importance of the form of Aristotle's philosophical works, mentions as an aside that, "Even in the case of Plato, the importance of the form for the understanding of his particular thought has often been overlooked for long periods; departmental philosophers and students ofliterature in particular are always prone to consider it as something literary which had no material significance for Plato, in spite of the fact that it is unique in die history of philosophy. By now, however, most persons know mat the study of the development of the form ofhis writing is one of me main keys to a philosophical understanding of him." ' In spite ofJaeger's contention that most contemporary interpreters of Plato are aware of the significance of investigating the dramatic form for an understanding of a dialogue's content, a survey of the literature on Plato shows that interpreters often abandon such a concern in their own approach to his dialogues. For example, many interpreters treat dialogues as treatises, ignoring the dramatic features in order to concentrate on the examination of the logical, epistemológica!, ethical or other philosophical aspects of the argumentation in a single dialogue or group ofdialogues; as a result interpreters tend to separate the content from the form of Plato's works.2 The effect of this approach is one-sided, for, although such interpretations attempt to do justice to the arguments, they ignore the dramatic features of the dialogues and their bearing on an interpretation of die philosophical substance. Currently a growing number of interpreters of Plato in Europe and North America hold that a consideration of the form of Plato's dialogues is important 32 Arthur A. Krentz33 for an understanding oftheir content and philosophical message.3 1 am in agreement with this position and in this article I consider some reasons that may have led Plato to adopt dialogue as his medium of philosophical expression and attempt to show how attention to the dialogue form shapes the interpretation of their content. Unlike his philosophical predecessors who cast their writings in the form of extended poems, aphorisms, or treatises "On Nature," Plato wrote dramas. That the dramatic form ofhis writings is not incidental to his philosophical purposes becomes apparent as one considers how Plato presents philosophy in a fundamentally different way from that of his predecessors and successors who adopted the essay and treatise as the paradigm ofphilosophical communication. In a philosophical work such as a treatise, an author ordinarily attempts to state his own position on issues under discussion as clearly and as forcefully as possible. This, however, is not the primary aim of Plato's works, for certain features of his dramas indicate that he deliberately concealed his own views. Of special note in this regard is the fact that Plato never speaks on his own behalf in the discourses he creates. There is no character named "Plato" unequivocally declaring the author's own position.4 Instead a variety of interlocutors ask questions, investigate philosophical problems, and puzzle over solutions while Plato remains noticeably silent. This silence of Plato indicates that he did not regard the unequivocal presentation of his own views to be of paramount importance. If this had been his aim, Plato had only to write a dialogue which included himselfas one ofthe characters clearly stating his own position. Having engaged in many philosophical discussions with Socrates and with his own students, Plato could have written a dialogue based on such conversations. His not doing so is sufficient to show that he did not use his writings as a primary vehicle for transmitting his own position in his own words. Nor did Plato use... (shrink)

The painter "takes his body with him."Nevertheless, Renoir was looking at the sea.Close! stand close to me, Starbuck; let me look into a human eye.The painter takes his body with him—he looks at what he sees and what he sees looks back at him. Perception takes place in the exchange, in time and in the world, not only between people or between living things but also between "subject" and "object," between perceiver and perceived. In this exchange that Maurice Merleau-Ponty calls (...) "the chiasm"—"this mediation through reversal"—something direct and active takes place. Before we can know or say what we're seeing, before we divide what we see into things or kinds of things, before naming and measurement, assertion and... (shrink)

We agree with Rachlin's aim to account for altruism within existing theory. However, his argument is implicitly dependent on social and cognitive constructs that are explicitly identified in other social-psychological theories. The account does not advance theory beyond available constructs (e.g., self-categorizations, motives, values, role-identities, and social structure), and Rachlin's implicit use of these strains the behaviorist account.

According to Heidegger, "mortals live in the speaking of language"—to respond genuinely to language is to bring human being into existence. The Indo-European root gen -, meaning "to beget"—with derivatives including "kin," "kind," "king," "generation," "gentle," "gender," "native," "nation," and "nature"—is an index to two central questions in Shakespeare's plays: "Are human beings, by nature, kind?" and "Are the gods kind?" King Lear finds himself in a world of gen - topsy-turvy. His response to language and to the absent gods (...) recalls us to our own mortal being. (shrink)

Affective disposition theory explains well the process of enjoying hero narratives but not the appeal of narratives featuring antiheroes. Recent antihero studies suggest that character identification and moral disengagement might be important factors in the enjoyment of such fare. The current study builds on this work. A sample of 101 self-identified fans and nonfans of the television series 24 viewed a condensed version of Season 1, providing evaluation of various protagonist perceptions, moral judgments, and emotional responses to the narrative, as (...) well as overall enjoyment. As expected, fans reported greater liking of the protagonist and greater enjoyment. But more importantly, regression analyses illuminated key differences between the groups in terms of the factors predicting enjoyment, providing a clearer picture of how we enjoy antihero narratives.

The matrix notation of paper I is extended to include first-rank spinors expressed as two-component spin-vectors. Well-known two-component and four-component spinor equations are expressed in this notation. In addition, it is shown how other covariant wave equations can easily be invented. A certain nonlinear equation is found to have only positive-energy solutions for particles and antiparticles.

Respect for victims requires that we have social systems for punishing and condemning (reproving) serious crimes. But, the conditions of social marginalization and political subordination of the communities from which an overwhelming number of prisoners in the United States come place serious barriers in the face of effective reprobation. Mass incarceration makes this problem worse by disrupting and disrespecting entire communities. While humanities education in the prisons is far from a total solution, it is one way to make reprobation meaningful, (...) so long as the prison classroom is a place where the educators’ values are also put at risk.

Eyewitnesses to crimes sometimes search for a culprit on social media before viewing a police lineup, but it is not known whether this affects subsequent lineup identification accuracy. The present online study was conducted to address this. Two hundred and eighty-five participants viewed a mock crime video, and after a 15–20 min delay either viewed a mock social media site including the culprit, viewed a mock social media site including a lookalike, or completed a filler task. A week later, participants (...) made an identification from a photo lineup. It was predicted that searching for a culprit on social media containing the lookalike would reduce lineup identification accuracy. There was a significant association between social media exposure and lineup accuracy for the Target Present lineup, but for the Target Absent lineup there was no significant association with lineup identification accuracy. The results suggest that if an eyewitness sees a lookalike when conducting a self-directed search on social media, they are less likely to subsequently identify the culprit in the formal ID procedure.

While ethical conflicts in the provision of healthcare are common, the current third-party mediator model is limited by a lack of expert ethical mediators, who are often not on site when conflict escalates. In order to improve clinical outcomes in situations such as conflicts at the end of life, we suggest that clinicians—physicians, nurses and social workers—be trained to prevent and deescalate emerging conflicts. This can be achieved using a mediation model framed by a communication-training approach. A case example is (...) presented and the model is discussed. The implication of this preventative/early intervention model for improving clinical outcomes, in particular end-of life conflict, is considered. (shrink)
