All lives contain negative events, but how we think about these events differs across individuals; negative events often include positive details that can be remembered alongside the negative, and the ability to maintain both representations may be beneficial. In a survey examining emotional responses to the 2013 Boston Marathon bombings, the current study investigated how this ability shifts as a function of age and individual differences in initial experience of the event. Specifically, this study examined how emotional importance, involvement, and (...) self-reported surprise upon hearing about the event related to the tendency to report focusing on the negative and positive aspects of the bombings. Structural equation models revealed that while greater emotional importance and surprise were associated with a greater focus on negative elements, involvement and age were associated with increased consideration of positive aspects. Further, emotional importance was more strongly related to an increased focus on negative aspects for young adults and an increased focus on positive aspects for older adults, highlighting a tendency for older adults to enhance positive features of an otherwise highly negative event.

Objective: To develop an approach for seeking informed consent to examine tissues retained from a previous study of sudden infant death syndrome as part of a study on asthma, and to document responses and participation rate.Design: Pilot open-ended approach to 10 volunteer SIDS parents, followed by staged approach to seek consent from the target SIDS families for the asthma study.Participants: Parents of SIDS infants known to SIDS and Kids Victoria and parents of SIDS infants from the 1991–2 SIDS in Victoria (...) case–control study.Main outcomes: Qualitative responses of the piloted parents and study parents, and participation rates.Results: The pilot group responses were used to refine the written material to be provided. Of the 72 families for which contact details were available, 45 gave verbal consent for contact by the Victorian Institute of Forensic Medicine regarding the asthma study, three refused and 24 did not respond to two letters. Thirty-three completed consent forms, all positive for participation in the asthma study, giving a positive response rate of 73% .Conclusions: The use of postmortem tissue for research is acceptable to the next of kin when an approach is sensitive to their concerns and needs and is made by experienced counsellors from a familiar organisation. Despite the painful memories evoked by the approach of the research group, the acceptance rate among those who could be contacted was high. (shrink)

Archaeological excavations carried out at Pentridge Prison discovered the ruins and foundations of three panopticon exercise yards. This paper details the scope and observations of the excavation program and discusses the influence of Jeremy Bentham’s panopticon model on penal reform and prison design in Australia in the middle of the 19th Century.

Constructive Neutral Evolution is an evolutionary mechanism that can explain much molecular inter-dependence and organismal complexity without assuming positive selection favoring such dependency or complexity, either directly or as a byproduct of adaptation. It differs from but complements other non-selective explanations for complexity, such as genetic drift and the Zero Force Evolutionary Law, by being ratchet-like in character. With CNE, purifying selection maintains dependencies or complexities that were neutrally evolved. Preliminary treatments use it to explain specific genetic and molecular structures (...) or processes, such as retained gene duplications, the spliceosome, and RNA editing. Here we aim to expand the scope of such explanation beyond the molecular level, integrating CNE with Multi-Level Selection theory, and arguing that several popular higher-level selection scenarios are in fact instances of CNE. Suitably contextualized, CNE occurs at any level in the biological hierarchy at which natural selection as normally construed occurs. As examples, we focus on modularity in protein–protein interaction networks or “interactomes,” the origin of eukaryotic cells and the evolution of co-dependence in microbial communities—a variant of the “Black Queen Hypothesis” which we call the “Gray Queen Hypothesis”.

The aim of UK-REACH (“The United Kingdom Research study into Ethnicity And COVID-19 outcomes in Healthcare workers”) is to understand if, how, and why healthcare workers (HCWs) in the United Kingdom (UK) from ethnic minority groups are at increased risk of poor outcomes from COVID-19. In this article, we present findings from the ethical and legal stream of the study, which undertook qualitative research seeking to understand and address legal, ethical, and social acceptability issues around data protection, privacy, and information (...) governance associated with the linkage of HCWs’ registration data and healthcare data. We interviewed 22 key opinion leaders in healthcare and health research from across the UK in two-to-one semi-structured interviews. Transcripts were coded using qualitative thematic analysis. Participants told us that a significant aspect of Big Data research in public health is varying drivers of mistrust—of the research itself, research staff and funders, and broader concerns of mistrust within participant communities, particularly in the context of COVID-19 and those situated in more marginalised community settings. However, despite the challenges, participants also identified ways in which legally compliant and ethically informed approaches to research can be crafted to mitigate or overcome mistrust and establish greater confidence in Big Data public health research. Overall, our research indicates that a “Big Data Ethics by Design” approach to research in this area can help assure (1) that meaningful community and participant engagement is taking place and that extant challenges are addressed, and (2) that any new challenges or hitherto unknown unknowns can be rapidly and properly considered to ensure potential (but material) harms are identified and minimised where necessary. Our findings indicate such an approach, in turn, will help drive better scientific breakthroughs that translate into medical innovations and effective public health interventions, which benefit the publics studied, including those who are often marginalised in research.

The authors review the empirical literature in order to assess which variables are postulated as influencing ethical beliefs and decision making. The variables are divided into those unique to the individual decision maker and those considered situational in nature. Variables related to an individual decision maker examined in this review are nationality, religion, sex, age, education, employment, and personality. Situation specific variables examined in this review are referent groups, rewards and sanctions, codes of conduct, type of ethical conflict, organization effects, (...) industry, and business competitiveness. The review identifies the variables that have been empirically tested in an effort to uncover what is known and what we need to know about the variables that are hypothesized as determinants of ethical decision behavior.

Existing social disparities in the United States are inconsistent with the promise of democracy; therefore, there was a need for critical conceptualization of the first principles that undergird American democracy and the genesis of democratic social change in America. This constructivist grounded theory study aimed to construct a grounded theory that provides an understanding of the process of American democratic social change as it emerged from the nation’s founding documents. A post hoc polytheoretical framework including Foucault’s, Bourdieu’s, and Marx and (...) Engels’s theories of power was used to understand power dynamics. The research question focused on understanding the process of democratic social change in America. The sample comprised the Articles of Confederation, the U.S. Declaration of Independence, The Federalist Papers, and the U.S. Constitution. The documents were retrieved from the National Archives and Library of Congress. The data analysis plan incorporated successive comparison, situational and dramaturgical analysis, deconstruction, and perspective taking as strategies. The result was the construction of a democratic social change process theory preceded by five grounded theories: (a) first principles of democracy, (b) first principles of democracy conceptual framework, (c) socio-ethical principles of democracy, (d) demoralizing process, and (e) either-or approach to democracy. Positive social change implications include applying a democratic social change process to future social change endeavors across domains and levels of analysis, a normative framework for a republican form of government, and a tool to analyze and minimize the latent consequences of social justice policies.

The paper studies the impact of informational ambiguity on behalf of informed traders on history-dependent price behaviour in a model of sequential trading in financial markets. Following Chateauneuf et al., we use neo-additive capacities to model ambiguity. Such ambiguity and attitudes to it can engender herd and contrarian behaviour, and also cause the market to break down. The latter, herd and contrarian behaviour, can be reduced by the existence of a bid-ask spread.

IntroductionSymptoms of schizophrenia are closely related to aberrant language comprehension and production. Macroscopic brain changes seen in some patients with schizophrenia are suspected to relate to impaired language production, but this is yet to be reliably characterized. Since heterogeneity in language dysfunctions, as well as brain structure, is suspected in schizophrenia, we aimed to first seek patient subgroups with different neurobiological signatures and then quantify linguistic indices that capture the symptoms of “negative formal thought disorder”.MethodsAtlas-based cortical thickness values of 66 (...) patients with first-episode psychosis and 36 healthy controls were analyzed with hierarchical clustering algorithms to produce neuroanatomical subtypes. We then examined the generated subtypes and investigated the quantitative differences in MRS-based glutamate levels [in the dorsal anterior cingulate cortex ] as well as in three aspects of language production features: fluency, syntactic complexity, and lexical cohesion.ResultsTwo neuroanatomical subtypes among patients were observed, one with near-normal cortical thickness patterns while the other with widespread cortical thinning. Compared to the subgroup of patients with relatively normal cortical thickness patterns, the subgroup with widespread cortical thinning was older, with higher glutamate concentration in dACC and produced speech with reduced mean length of T-units and lower repeats of content words, despite being equally fluent.ConclusionWe characterized a patient subgroup with thinner cortex in first-episode psychosis. This subgroup, identifiable through macroscopic changes, is also distinguishable in terms of neurochemistry and language behavior. This study supports the hypothesis that glutamate-mediated cortical thinning may contribute to a phenotype that is detectable using the tools of computational linguistics in schizophrenia. (shrink)

Shocking, brilliant, and eccentric, the French author, translator, and artist Pierre Klossowski (1905-2001) exerted a profound effect on French intellectual culture throughout the twentieth century. The older brother of the painter Balthus, secretary to the novelist Andre Gide, friend to Geroges Bataille and Maurice Blanchot, and heralded as one of the most important voices in the French "return to Nietzsche" by Michel Foucault and Gilles Deleuze, Klossowski pursued his singular vision of mortal embodiment through a variety of scholarly manifestations. In (...) Such a Deathly Desire, Klossowski's original interpretation of Nietzsche's eternal return is developed around the enigmatic figure of the "demon," then deepened with provocative readings of Gide's correspondence; Barbey d'Aurevilly's novel A Married Proest; and the intertwining of language and death in the work of Bataille, Blanchot, and Brice Parain. The book concludes with the powerful essay "Nietzsche, Polytheism, and Parody," in which Klossowski articulates the consequences of the eternal return and the meaning of Nietzsche's genealogy of the fabulation of the world. Intersecting with and confounding a range of disciplines - including psychoanalysis, literary criticism, gender studies, and philosophy - Klossowski's critical writings on language, literature, and the aesthetics of embodiment remain powerful and original contributions to contemporary concerns in the theoretical humanities.

In lieu of an abstract, here is a brief excerpt of the content:The Controversy Between Schelling and Jacobi LEWIS S. FORD SCHELLING, ALONGWITH FICHTE, has suffered the fate of being labelled one of tIegel's predecessors. Richard Kroner provides the classic expression of this viewpoint in his monumental study, Von Kant bis Hegel, which examines Schelling's thought primarily for its contribution to Hegel's final synthesis.I In English we have Josiah Royce's sympathetic and lively account of Schelling's early romantic exuberance, regarded (...) as a transitional stage in the development of German idealism. 2 But this emphasis on the early ScheUing has led to an unfortunate neglect of his work subsequent to the break with Hegel in 1807. Schelling's romanticism, so ably documented by E. D. Hirsch, Jr., 3 can only be regarded as one phase in the total sweep of his thought, for, after the break with Hegel, Schelling produced at least three major works: the essay •ber das Wesen der menschlichen Freiheit,4 wrestling with the problem of evil and human freedom, the fragmentary Weltalter, 5 which in scope and dialectical intricacy should be compared with Hegel's Logic, and the Philosophie der Mythologie und Offenbarung, 6 furnishing a fundamental critique of the whole dialectical enterprise. Save for the essay on human freedom, however, none of these works were published during his lifetinm, as Schelling withdrew from the public eye after his controversies with Hegel and Jacobi. Thus the publishing histories of Schelling and Hegel are exactly reverse. Schelling rushed into print his early speculative gropings, while Hegel suppressed his/making the Ph~nomenologic des Geistes his first major publication. Then while Hegel's Logic and Encyclopedia were being publicly acclaimed, Schelling remained silent. This accident of history is largely responsible for the illusion that Schelling is the older of the two x (Tiibingen: J. C. B.

Paul Tillich's doctoral dissertations s and Ernst Cassirer's studies in post-Kantian thought 9 made serious inroads on this conception, yet the iIInsion persisted. Their insistence on the importance of the later Schelling has been brilliantly sustained by two recent studies: Horst Fuhrmans's Schellings Philosophie der Weltalter1~and Walter Schulz's Die Vollendung des deutschen Idealismus in der Spdtphilosophie Schellings, ~ and we may hope that the conventional estimate of Schelling will be drastically revised. Fuhrmans has demonstrated that the split between the early and the later Schelling must be placed in the year 1806 when he came in contact with Franz yon Bander in Munich, who encouraged him to delve deeper into the theological and cosmological ramifications of Jacob Boehme's thought. TM The reorientation this caused is apparent in the essay on human freedom, published in 1809, but it was not fully exploited until the... (shrink)

Two essays relating Thomas and Whitehead have recently appeared. Coming To Be by James W. Felt, S.J., modifies Thomas by replacing his substantial form with Whitehead’s notion of subjective aim, the essencein-the-making introduced by God to guide the occasion’s act of coming into being. Felt also substitutes subjective aim for matter as the means of individuation. This is one of Whitehead’s individuating principles, although a case can be made that matter (the multiplicity of past actualities as proximate matter) is another. (...) “God and Creativity” by Stephen T. Franklin develops a reconciliation of these two ultimates by conceiving of God as the source of creativity, and seeing creativity in terms of the Thomistic esse. In my reflections on this project I explore four alternativeswith respect to the source of creativity: (a) creativity as derived from the past; (b) creativity as inherent in the present; (c) God as the source of transitional creativity (Franklin); (d) God as the source of concrescent creativity (Ford). The last two differ with respect to being’s relation to becoming. Does being undergird becoming, or does becoming bring about being, such that apart from it there would be no being? Our theory of creation depends upon this question. (shrink)

Lexical Semantics is about the meaning of words. Although obviously a central concern of linguistics, the semantic behaviour of words has been unduly neglected in the current literature, which has tended to emphasize sentential semantics and its relation to formal systems of logic. In this textbook D. A. Cruse establishes in a principled and disciplined way the descriptive and generalizable facts about lexical relations that any formal theory of semantics will have to encompass. Among the topics covered in depth are (...) idiomaticity, lexical ambiguity, synonymy, hierarchical relations such as hyponymy and meronymy, and various types of oppositeness. Syntagmatic relations are also treated in some detail. The discussions are richly illustrated by examples drawn almost entirely from English. Although a familiarity with traditional grammar is assumed, readers with no technical linguistic background will find the exposition always accessible. All readers with an interest in semantics will find in this original text not only essential background but a stimulating new perspective on the field. (shrink)

A comprehensive introduction to the ways in which meaning is conveyed in language. Alan Cruse covers semantic matters, but also deals with topics that are usually considered to fall under pragmatics. A major aim is to highlight the richness and subtlety of meaning phenomena, rather than to expound any particular theory. Rich in examples and exercises, Meaning in Language provides an invaluable descriptive approach to this area of linguistics for undergraduates and postgraduates alike.

Background Making the right decisions, while simultaneously showing respect for patient autonomy, represents a great challenge to nursing home staff in the issues of life-prolonging treatment, hydration, nutrition and hospitalisation to dying patents in end-of-life. Objectives To study how physicians and nurses protect nursing home patients' autonomy in end-of-life decisions, and how they justify their practice. Design A qualitative descriptive design with analysis of the content of transcribed in-depth interviews with physicians and nurses. Participants Nine physicians and ten nurses in (...) 10 nursing homes in Norway. Results and interpretations Assessment of the patient's competence to consent to treatment is almost absent. The physicians build their practice on the principles of beneficence and nonmaleficence. Nurses tend to trust the patients' rejection of life support, even when the patients have difficulty speaking or suffer from dementia. Relatives were, according to the health personnel, included in decision-making processes to a very limited extent. However, futile life support is sometimes provided contrary to the physicians' judgement of what constitutes the patient's best interest on occasions when they are pressurised by next of kin. Conclusions The study reveals a need to improve decision-making routines according to ethical ideals and legislation. Conflicts between relatives and healthcare professionals in the decision-making process deflect the focus from searching for the best possible treatment for the terminal patient. Further discussion is required as to whether the concept of autonomy is applicable in situations in which the patient is impaired and dying. (shrink)

A three-valued propositional logic is presented, within which the three values are read as ?true?, ?false? and ?nonsense?. A three-valued extended functional calculus, unrestricted by the theory of types, is then developed. Within the latter system, Bochvar analyzes the Russell paradox and the Grelling-Weyl paradox, formally demonstrating the meaninglessness of both.

Bainbridge’s well known “Ironies of Automation” Analysis, design and evaluation of man–machine systems. Elsevier, Amsterdam, pp 129–135, 1983. https://doi.org/10.1016/B978-0-08-029348-6.50026-9) laid out a set of fundamental criticisms surrounding the promises of automation that, even 30 years later, remain both relevant and, in many cases, intractable. Similarly, a set of ironies in technologies for sensor driven self-quantification is laid out here, spanning from instrumental problems in human factors design to much broader social problems. As with automation, these ironies stand in the way (...) of many of the promised benefits of these wearable technologies. It is argued here that without addressing these ironies now, the promises of wearables may not come to fruition, and instead users may experience outcomes that are opposite to those which the designers seek to afford, or, at the very least, those which consumers believe they are being offered. This paper describes four key ironies of sensor driven self-quantification: know more, know better versus no more, no better; greater self-control versus greater social control; well-being versus never being well enough; more choice versus erosion of choice.

Corporate social responsibility, sustainability and acting ethically are all accepted business aims, but their meaning and implementation in a global context is far less clear-cut. Global Business Ethics cuts through the confusion to provide a coherent basis for ethical decision-making within the complications of the international business landscape. Underpinned by theory and including worked-through examples of ethical dilemmas and their solutions, this textbook will guide the reader beyond theory to real-world business decisions. Practical tools such as decision trees and suggested (...) principles to apply in dilemma situations give readers the skills and confidence to tackle the ethical challenges they face. A unique working code of ethics is provided as a model with guidance to readers for adaptation and implementation. Case studies include: Walmart, Hershey's, Citibank, Ford, Nike, Johnson & Johnson, Harley- Davidson, The Body Shop and Procter and Gamble. A chapter on the legal aspects of ethics provides clear guidance on the complex relationship between law and ethics in international business. The final part takes an in-depth look at the practical application of ethics in business life. Covering all the major theories of ethics, including an examination of the role of quantification of ethics, Global Business Ethics demonstrates how their principles can be applied to inform better business decisions.

In contrast with Ford’s essay, David R. Griffin presents a catalogue of the differences between the two philosophers from a "Hartshornian" perspective. Strangely, perhaps the least helpful contribution comes from Hartshorne himself, whose "Ideas and Theses of Process Philosophers" is simply a highly schematic outline. Completing the volume are essays by William O’Meara on Hartshorne’s methodology, and by Frederic Frost on relativity theory and Hartshorne’s dipolar conception of God. In general, the book suffers from repetition; many of the same (...) issues recur in the essays, at times with significantly different interpretations, but frequently with only the slightest modification of accent. While its flaws cannot be ignored, Two Process Philosophers does possess the virtue of focusing upon the genuine diversity within the tradition of process philosophy.-D.F.D. (shrink)

Objectives: To discover the current state of opinion and practice among doctors in Victoria, Australia, regarding end-of-life decisions and the legalisation of voluntary euthanasia. Longitudinal comparison with similar 1987 and 1993 studies.Design and participants: Cross-sectional postal survey of doctors in Victoria.Results: 53% of doctors in Victoria support the legalisation of voluntary euthanasia. Of doctors who have experienced requests from patients to hasten death, 35% have administered drugs with the intention of hastening death. There is substantial disagreement among doctors concerning the (...) definition of euthanasia.Conclusions: Disagreement among doctors concerning the meaning of the term euthanasia may contribute to misunderstanding in the debate over voluntary euthanasia. Among doctors in Victoria, support for the legalisation of voluntary euthanasia appears to have weakened slightly over the past 17 years. Opinion on this issue is sharply polarised. (shrink)

Primordial emotions are the subjective element of the instincts which are the genetically programmed behaviour patterns which contrive homeostasis. They include thirst, hunger for air, hunger for food, pain and hunger for specific minerals etc.There are two constituents of a primordial emotion—the specific sensation which when severe may be imperious, and the compelling intention for gratification by a consummatory act. They may dominate the stream of consciousness, and can have plenipotentiary power over behaviour.It is hypothesized that early in animal evolution (...) complex reflex mechanisms in the basal brain subserving homeostatic responses, in concert with elements of the reticular activating system subserving arousal, melded functionally with regions embodied in the progressive rostral development of the telencephalon. This included the emergent limbic and paralimbic areas, and the insula. This phylogenetically ancient organization subserved the origin of consciousness as the primordial emotion, which signalled that the organisms existence was immediately threatened. Neuroimaging confirms major activations in regions of the basal brain during primordial emotions in humans. The behaviour of decorticate humans and animals is discussed in relation to the possible existence of primitive awareness.Neuroimaging of the primordial emotions reveals that rapid gratification of intention by a consummatory act such as ingestion causes precipitate decline of both the initiating sensation and the intention. There is contemporaneous rapid disappearance of particular regions of brain activation which suggests they may be part of the jointly sufficient and severally necessary activations and deactivations which correlate with consciousness [Crick, F. & Koch, C. . A framework for consciousness. NatureNeuroscience,6, 119–126]. (shrink)

In a published exchange, Richard Robinson and Roy A. Sorenson debate the matter of whether begging the question is a fallacy; Robinson thinks it is not, but Sorenson argues that it is.

While Teng is right to note that Robinson and Sorenson are talking past each other, he incorrectly diagnoses the source of this miscommunication. In this paper, then, I offer (...) what I take to be a more illuminating distinction 3; viz. that between logical and rhetorical fallacies 3; and employ that distinction to resolve the debate.

Recently, commentators close to and within the UK government have claimed that patient choice can increase equity in the context of the National Health Service. This article critically examines the basis for this claim through analysis of recent speeches and publications authored by secretaries of state for health and their policy advisers.

The (...) limited justification that is “framed in causal explanations” of inequity has suffered from an apparent disregard of the available evidence. (shrink)

Traditional explanations of multistable visual phenomena (e.g. ambiguous figures, perceptual rivalry) suggest that the basis for spontaneous reversals in perception lies in antagonistic connectivity within the visual system. In this review, we suggest an alternative, albeit speculative. explanation for visual multistability - that spontaneous alternations reflect responses to active, programmed events initiated by brain areas that integrate sensory and non-sensory information to coordinate a diversity of behaviors. Much evidence suggests that perceptual reversals are themselves more closely related to the expression (...) of a behavior than to passive sensory responses: (1) they are initiated spontaneously, often voluntarily, and are influenced by subjective variables such as attention and mood; (2) the alternation process is greatly facilitated with practice and compromised by lesions in non- visual cortical areas; (3) the alternation process has temporal dynamics similar to those of spontaneously initiated behaviors; (4) functional imaging reveals that brain areas associated with a variety of cognitive behaviors are specifically activated when vision becomes unstable. In this scheme, reorganizations of activity throughout the visual cortex, concurrent with perceptual reversals, are initiated by higher, largely non- sensory brain centers. Such direct intervention In the processing of the sensory input by brain structures associated with planning and motor programming might serve an important role in perceptual organization, particularly in aspects related to selective attention.

Objections to the use of assistive technologies in elite sports are generally raised when the technology in question is perceived to afford the user a potentially “unfair advantage,” when it is perceived as a threat to the purity of the sport, and/or when it is perceived as a precursor to a slippery slope toward undesirable changes in the sport. These objections rely on being able to quantify standards of “normal” within a sport so that changes attributed to the use of (...) assistive technology can be judged as causing a significant deviation from some baseline standard. This holds athletes using assistive technologies accountable to standards that restrict their opportunities to achieve greatness, while athletes who do not use assistive technologies are able to push beyond the boundaries of these standards without moral scrutiny. This paper explores how constructions of fairness and “normality” impact athletes who use assistive technology to compete in a sporting venue traditionally populated with “able-bodied” competitors. It argues that the dynamic and obfuscated construction of “normal” standards in elite sports should move away from using body performance as the measuring stick of “normal,” toward alternate forms of constructing norms such as defining, quantifying, and regulating the mechanical actions that constitute the critical components of a sport. Though framed within the context of elite sports, this paper can be interpreted more broadly to consider problems with defining “normal” bodies in a society in which technologies are constantly changing our abilities and expectations of what normal means.
