'Numbers and Proofs' presents a gentle introduction to the notion of proof to give the reader an understanding of how to decipher others' proofs as well as construct their own. Useful methods of proof are illustrated in the context of studying problems concerning mainly numbers (real, rational, complex and integers). An indispensable guide to all students of mathematics. Each proof is preceded by a discussion which is intended to show the reader the kind of thoughts they might have before any (...) attempt proof is made. Established proofs which the student is in a better position to follow then follow. Presented in the author's entertaining and informal style, and written to reflect the changing profile of students entering universities, this book will prove essential reading for all seeking an introduction to the notion of proof as well as giving a definitive guide to the more common forms. Stressing the importance of backing up "truths" found through experimentation, with logically sound and watertight arguments, it provides an ideal bridge to more complex undergraduate maths.

In recent years, two important books by Yoram Cohen and Matthew Rutz have marked significant progress in research on the archives of Late Bronze Age Emar in northwestern Syria. Both of them approach Emar by way of its scribes. Cohen undertakes a systematic review of all named scribes identified in texts associated with Emar, while Rutz narrows his object to the building that yielded by far the largest number of excavated tablets. This work is foundational to future work on the (...) Emar texts even as it calls for cautious consideration. (shrink)

This Article focuses both on the changes that have been made to the legal framework governing post-separation parenting of children in Australia, as well as the processes and discourses via which these matters have been dealt with and debated. Alone among comparable common law jurisdictions such as Canada, the United States, and England, Australia’s family law legislation, and the significant changes made to it in the past fifteen years, can be seen to have been particularly responsive to the lobbying of (...) fathers’ rights groups. It will be suggested that changes to the legislative framework that governs family law in Australia have taken place, at best, without any clear rationale or need and perhaps more problematically, have at times flown in the face of, rather than been undertaken by reference to, the evidence-based research about post-separation parenting practices and what we know about children’s welfare or best interests, the paramount consideration that underpins decision-making in this field. The purpose of this discussion is to attempt to posit some possible explanations for this distinctive path of Australian family law “reform”. (shrink)

ABSTRACT In this paper I examine some of the issues surrounding the moral status of the therapy known as ‘deprogramming’. I argue against the extreme view that all deprogrammings are morally impermissible. In certain instances deprogramming is morally justified because it is quite capable of restoring the conditions needed for the exercise of autonomy. The view of autonomy I am following is that constructed by Gerald Dworkin, wherein two conditions must be met in describing a person as autonomous—authenticity and procedural (...) independence. Autonomy of another type, described by Dworkin as authenticity plus substantive independence, may be lost by persons involved in cults but in those instances deprogramming as reconstructed in this paper is not a morally justified measure.

1. What is it according to Berkeley for bodies to exist in the mind? Maybe no simple or single answer to this question fits everything that he says about it in the Principles and Dialogues , but I think he gives or suggests an answer in Principles section 49 that he may have to give or be willing to accept across the board. The trouble is that this answer comes with a fairly high price.

Critical development and food studies scholars argue that the current food security paradigm is emblematic of a ‘New Green Revolution’, characterized by agricultural intensification, increasing reliance on biotechnology, deepening global markets, and depeasantization. High-profile examples of this model are not hard to find. Less examined, however, are food-security programs that appear to work at cross-purposes with this model. Drawing on the case of Feed the Future in Guatemala, I show how USAID engages in activities that valorize ancestral crops, subsistence production, (...) and agroecological practices. Rather than the result of macro-level planning—of either the New Green Revolution or a greener reform regime—I argue that nonconforming food security projects can be traced to individual actors and their interactions on the ground. I draw on an ‘interface approach’ (Long 1990 ), focusing on the lifeworlds of development workers, their interfaces with each other, and with the to-be-developed. Doing so reveals how food security projects are significantly shaped by the relationships and interests of development actors enmeshed in particular organizational and national settings. This research contributes a fresh perspective on the food security paradigm and its role within the ‘corporate food regime’. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Rhetorical Investigations: Studies in Ordinary Language Criticism, and: Ordinary Language Criticism: Literary Thinking after Cavell after WittgensteinRichard FlemingRhetorical Investigations: Studies in Ordinary Language Criticism, by Walter Jost; 368 pp. Charlottesville: University of Virginia Press, 2004, $55.00. Ordinary Language Criticism: Literary Thinking after Cavell after Wittgenstein, edited by Kenneth Dauber and Walter Jost; 353 pp. Evansville: Northwestern University Press, 2003, $29.95 paper.On the question of ordinary language criticism and (...) philosophy, "Who pleases whom?" Judging by many of the articles, essays, and books of the last decade the answer might be: almost nobody pleases anyone. Whether in appreciation or incomprehension of its importance and substance, renewed efforts at understanding, redirections of thinking, and disappointments and frustrations with the [End Page 209] subject-matter are prevalent when ordinary language is the topic of discussion. These two recent books tend to strengthen this assessment. Rhetorical Investigations is a sustained effort to "revisit" and "rethink" grammatical (conceptual) reflections on ordinary language and literature; and in so doing provide a "reinvention" of characteristics of literary theory through an extensive and detailed consideration of the work of Robert Frost. Although sometimes overreaching in its efforts (particularly when discussing logic), it imaginatively uses rhetoric and ordinary language concerns as a means of direction and focus for new, explanatory discussions in literary—philosophical analysis. Ordinary Language Criticism (part of the general series, "Rethinking Theory," edited by Gary Saul Morson) is a diverse and uneven collection of fifteen articles concerning and using ordinary language interests, several of which (R. M. Berry, Garry L. Hagberg, Richard Eldridge, Gerald L. Bruns) valuably repay the diligence needed to discover them in 350 plus pages. The text includes an editors' introduction that voices the wish to "return criticism to its grounds in the 'ordinary' or natural language we all speak" and (unsuccessfully but lustily) pronounces and explains "ordinary language criticism" as a new yet traditional area of study. ("New" in that it takes "as its point of departure" the ordinary language philosophy of Wittgenstein, and "traditional" in that "all criticism is really ordinary language criticism.") The editors further undertake in this introduction the endeavor to sketch something of a program for the book, meant to show connected promptings among the various writings, whereas the specific authors themselves settle down quickly and separately to a critical work at hand without particular references to each other. Both of these texts, like others in this field of study before, valuably raise questions and apprehensions of what use there is in talk about ordinary language. The best of such material provides provocations for thinking that are to be found nowhere else. The worst of such books and articles is that they prejudice sensible people against the study of the ordinary.Can one conceive of something to say about these two books that the authors and the current readers haven't already heard or of which they can be profitably reminded? It certainly would not be wise to presume such a grand stand. This is a large question to which only a small answer might be given here. Setting aside the perhaps undiscussable differences of what we each see of primary importance in the primary texts and how best to read them, one issue and difference of understanding, specific and plain enough to state briefly, perhaps usefully does arise. It is a lack of a clear sense of the "ordinary," its distinctiveness, its implications; and thereby a continuation of many of the confusions that have inhabited philosophical and literary writing before and after Wittgenstein turned his attention to the matter. Is this not partly why frustrations of understanding, disagreements in thinking, and displeasures in discussion remain pervasive and unrelenting?This difficulty and difference with such work can only prove worthwhile introducing, however, against a background of agreement over the centrality [End Page 210] of a cluster of issues, of which three might be specified: a first agreement concerns the sensitivity or fear that something is being missed or remains unintelligible in the culture about the ordinary; a respect for the ordinary is a needed, often unnoticed beginning of our reflections. Rhetorical Investigations importantly develops its analyses from such a perspective (Jost's... (shrink)

1. ‘“But aren't you saying that all that happens is that he moans, and that there is nothing behind it?” I am saying that there is nothing behind the moaning ’ . This passage seems to me to epitomize a conception of the mind and its relation to the body found in the later work of Wittgenstein. It will be convenient to write as if this is his view of the mind. He suggests elsewhere that he is not advancing philosophical (...) theses in his later work; so maybe this view is not a philosophical thesis in some relevant sense; or maybe Wittgenstein is not wholly consistent; or maybe he puts it forward only dialectically, and in other philosophical contexts would have espoused other views of the mind as much as he espouses this one. In any case, what does this one amount to? ‘There is nothing behind the moaning.’ What does this mean? (shrink)

When there have been substantial failures by institutional leadership in their oversight responsibility to protect research integrity, the public should demand that these be recognized and addressed by the institution itself, or the funding bodies. This commentary discusses a case of research failures in developing genomic predictors for cancer risk assessment and treatment at a leading university. In its review of this case, the Office of Research Integrity, an agency within the US Department of Health and Human Services, focused their (...) report entirely on one individual faculty member and made no comment on the institution’s responsibility and its failure to provide adequate oversight and investigation. These actions missed an important opportunity to emphasize the institution’s critical responsibilities in oversight of research integrity and the importance of institutional transparency and accountability.

The executive hypothesis of self-regulation places cognitive information processing at the center of self-regulatory success/failure. While the hypothesis is well supported by cross-sectional studies, no study has tested its primary prediction, that temporary lapses in executive control underlie moments of self-regulatory failure. Here, we conducted a naturalistic experiment investigating whether short-term variation in executive control is associated with momentary self-regulatory outcomes, indicated by negative affect reactivity to everyday stressors. We assessed working memory capacity (WMC) through ultra-brief, ambulatory assessments on smart (...) phones five times per day in a 7-day ecological momentary assessment (EMA) study involving college-aged adults. We found that participants exhibited more negative affect reactivity to stressor exposures during moments when they exhibited lower than usual WMC. Contrary to previous findings, we found no between-person association between WMC and average stress reactivity. We interpret these findings as reflecting the role of executive control in determining one’s effective capacity to self-regulate. (shrink)

Background The fourth section of the 1967 Abortion Act states that individuals (including health care practitioners) do not have to participate in an abortion if they have a conscientious objection. A conscientious objection is a refusal to participate in abortion on the grounds of conscience. This may be informed by religious, moral, philosophical, ethical, or personal beliefs. Currently, there is very little investigation into the impact of conscientious objection on service users in Britain. The perspectives of service users are imperative (...) in understanding the real-world consequences and potential impact of conscientious objection and should be considered when creating and reviewing policies and guidelines. This research provided a platform for women and those who can become pregnant to share their experiences and opinions at a time when these voices are largely excluded in the great tradition of Western political philosophy and law-making processes. Method Five service users were interviewed using a narrative interview approach to uncover their abortion journeys and experiences of conscientious objection. Findings The findings were presented as found poems and uncovered that doctors are not always: informing service users that they have a conscientious objection to abortion, giving service users enough information to access abortion (indirect referral), treating them non-judgmentally, and providing medically correct information. Service users did not experience burdens such as long waiting times and were still able to access legal abortion. However, service users did experience negative emotional effects, as they were often left feeling scared, angry, and hopeless when they were not referred and/or were mistreated. Conclusions Findings indicate that conscientious objection could work in practice. However, it is currently failing some individuals on an emotional level, as not all doctors are adhering to guidelines. Conscientious objection in Britain needs to be addressed, to ensure service users receive fair, impartial, non-judgmental care. (shrink)

Our understanding of the universe has grown rapidly in recent decades. We’ve discovered evidence of water in nearby planets, discovered planets outside our solar system, mapped the genomes of thousands of organisms, and probed the very origins and limits of life. The scientific perspective of life-as-it-could-be has expanded in part by research in astrobiology, synthetic biology, and artificial life. In the face of such scientific developments, we argue there is an ever-growing need for universal biology, life-as-it-must-be, the multidisciplinary study of (...) non-contingent aspects of life as guided by biological theory and constrained by the universe. We present three distinct but connected ways of universalizing biology—with respect to characterizing aspects of life everywhere, with respect to the explanatory scope of biological theory, and with respect to extending biological insights to the structure of nonbiological entities. For each of these, we sketch the theoretical goals and challenges, as well as give examples of current research that might be labeled universal biology. (shrink)

This article examines how private equity returns in Asia are related to levels of legal protection and corruption. We utilize a unique data set comprising over 750 returns to private equity transactions across 20 developing and developed countries in Asia. The data indicate that legal protections are an important determinant of private equity returns in Asia, but also that private equity managers are able to mitigate the potential for corruption. The quality of legal system (including legal protections) is positively related (...) to returns. Inefficient legal protections negatively impact transaction structures and economic certainty when exiting investments. We also find that private equity managers, irrespective of the quality of legal system they are operating within, can mitigate the potential impact of corruption. Private equity returns are higher in countries with higher levels of corruption, controlling for legal systems. This finding is consistent with the view that private equity managers bring about organizational change to alleviate the costs of corruption. Our findings are robust to inclusion of controls for Hofstede cultural variables, economic conditions, and transaction specific characteristics, as well as consideration of econometric sample selection methods for unexited investments.

Most current dental ethics curricula use a deontological approach to biomedical and dental ethics that emphasizes adherence to duties and principles as properties that determine whether an act is ethical. But the actual ethical orientation of students is typically unknown. The purpose of the current study was to determine the ethical orientation of dental students in resolving clinical ethical dilemmas. First-year students from one school were invited to participate in an electronic survey that included eight vignettes featuring ethical conflicts common (...) to the health care setting. The Multidimensional Ethics Scale was used to evaluate the students’ ethical judgments of these conflicts. Students rated each vignette along 13 ethically relevant items using a 7-point scale. Nine of the thirteen items were analyzed because they represent the dominant ethical theories, including deontology. One hundred sixteen dental students successfully completed the survey. Of the analyzed items, those associated with deontology had comparatively weak associations with whether students judged the action to be ethical and whether students judged themselves likely to perform the action. Whether an action was judged to be caring had the strongest association with whether the action was judged to be ethical and whether students judged themselves likely to perform the action. These results suggest that adherence to duties or principles has weaker association with students’ ethical judgments and behavior compared to caring, which was found to be more influential in their ethical judgments and behavior. Current dental school curricula with a primary focus on deontology may no. (shrink)

Clatterbuck et al. (Biol Philos 28: 577–592, 2013) argue that there is no fact of the matter whether selection dominates drift or vice versa in any particular case of evolution. Their reasons are not empirically based; rather, they are purely conceptual. We show that their conceptual presuppositions are unmotivated, unnecessary and overly complex. We also show that their conclusion runs contrary to current biological practice. The solution is to recognize that evolution involves a probabilistic sampling process, and that drift is (...) a deviation from probabilistic expectation. We conclude that conceptually, there are no problems with distinguishing drift from selection, and empirically—as modern science illustrates—when drift does occur, there is a quantifiable fact of the matter to be discovered.

Human behavior depends on the ability to effectively introspect about our performance. For simple perceptual decisions, this introspective or metacognitive ability varies substantially across individuals and is correlated with the structure of focal areas in prefrontal cortex. This raises the possibility that the ability to introspect about different perceptual decisions might be mediated by a common cognitive process. To test this hypothesis, we examined whether inter-individual differences in metacognitive ability were correlated across two different perceptual tasks where individuals made judgments (...) about different and unrelated visual stimulus properties. We found that inter-individual differences were strongly correlated between the two tasks for metacognitive ability but not objective performance. Such stability of an individual’s metacognitive ability across different perceptual tasks indicates a general mechanism supporting metacognition independent of the specific task. (shrink)

This book delivers a definitive contribution to the understanding of Habermas's oeuvre as it applies to education. The authors examine Habermas's contribution to pedagogy, learning and classroom interaction; the relation between education, civil society and the state; forms of democracy, reason and critical thinking; and performativity, audit cultures and accountability.

An important area of business ethics research focuses on how otherwise normal and law-abiding individuals can engage in acts of corruption. Key in this literature is the concept of rationalization. This is where individuals attempt to justify past and future corrupt deeds to themselves and others. In this article, we argue that rationalization often entails a process of overcompensation whereby the justification forwarded is excessive in relation to the actual act. Such over-rationalization provides an impetus for further and more serious (...) acts of illegality. Using a number of high profile cases, it is argued that this dynamic gap between the act and excessive rationalization can explain why corruption often escalates in severity and scope in the organization.

This paper develops the concept of the ‘continuum of destructiveness’ in relation to organizational corruption. This notion captures the slippery slope of wrongdoing as actors engage in increasingly dubious practices. We identify four kinds of individuals along this continuum in corrupt organizations, who range from complete innocence to total guilt. They are innocent bystanders, innocent participants, active rationalizers and guilty perpetrators. Traditional explanations of how individuals move from bystander status to guilty perpetrators usually focus on socialization and institutional factors. In (...) addition to these factors, we propose that the very distance between an act and its ethical consequences (ethical distance) may also play a determining role – if not always in the same way – in the transition process. Having developed this conceptual argument, we conclude with a discussion of managerial and research implications. (shrink)

The interdisciplinary French-American thinker René Girard (1923-2015) has been one of the towering figures of the humanities in the last half-century. The title of René Girard's first book offered his own thesis in summary form: romantic lie and novelistic truth [mensonge romantique et vérité romanesque]. And yet, for a thinker whose career began by an engagement with literature, it came as a shock to some that, in La Conversion de l'art, Girard asserted that the novel may be an “outmoded” form (...) for revealing humans to themselves. However, Girard never specified what, if anything, might take the place of the novel. This collection of essays is one attempt at answering this question, by offering a series of analyses of films that aims to test mimetic theory in an area in which relatively little has so far been offered. Does it make any sense to talk of vérité filmique? In addition, Mimetic Theory and Film is a response to the widespread objection that there is no viable “Girardian aesthetics.” One of the main questions that this collection considers is: can we develop a genre-specific mimetic analysis (of film), and are we able to develop anything approaching a “Girardian aesthetic”? Each of the contributors addresses these questions through the analysis of a film. (shrink)

In this article de Beauvoir defends a conception of literature as a kind of unveiling of something that exists outside itself, a mode of action which reveals certain truths about the world. What we call “literature” is eminently capable of grasping the world—a world which de Beauvoir, following Jean-Paul Sartre, conceives of as a “detotalized totality”; one that is real and independent of us, which exists for all, but is only graspable through our own projects and our perspectives. Yet far (...) from keeping us stranded within our unique subjectivities, literature restores to subjective experience its generality; it allows other to “taste” the world as it exists for others. We can communicate through literature because in it our world, our languages, and our projects overlap. Ultimately, for de Beauvoir, literature is what allows us to see the world as others see it—all the while remaining, irreducibly, ourselves. (shrink)

The paper problematises the reliability and ethics of using social media data, such as sourced from Twitter or Instagram, to carry out health-related research. As in many other domains, the opportunity to mine social media for information has been hailed as transformative for research on well-being and disease. Considerations around the fairness, responsibilities and accountabilities relating to using such data have often been set aside, on the understanding that as long as data were anonymised, no real ethical or scientific issue (...) would arise. We first counter this perception by emphasising that the use of social media data in health research can yield problematic and unethical results. We then provide a conceptualisation of methodological data fairness that can complement data management principles such as FAIR by enhancing the actionability of social media data for future research. We highlight the forms that methodological data fairness can take at different stages of the research process and identify practical steps through which researchers can ensure that their practices and outcomes are scientifically sound as well as fair to society at large. We conclude that making research data fair as well as FAIR is inextricably linked to concerns around the adequacy of data practices. The failure to act on those concerns raises serious ethical, methodological and epistemic issues with the knowledge and evidence that are being produced. (shrink)

In this article, Pierre Hadot examines the late philosophy of Ludwig Wittgenstein and the so-called “linguistic turn” in philosophy and the social sciences. Although certain interpreters of Wittgenstein have thought that Philosophical Investigations shows philosophy to be predicated on a series of confusions based on the misuse of language, Hadot argues contrarily that an understanding of Wittgenstein’s idea of “language games”—far from ending philosophy—allows us to see it anew and to discern the source of some of its deepest perplexities. Of (...) particular concern is the notion of the ancient idea of philosophical discourse as intrinsically connected to various forms of apprenticeship or spiritual formation. It is in this context that the supposed inconsistencies and unusual repetitions of ancient philosophy can be understood. Only from the Middle Ages do philosophical language games begin slowly to become detached from certain kinds of training, of pedagogies connected to forms of life, and become texts—and “systems”—in the sense of being written for the purposes of merely conventional reading.

The scientific study of consciousness emerged as an organized field of research only a few decades ago. As empirical results have begun to enhance our understanding of consciousness, it is important to find out whether other factors, such as funding for consciousness research and status of consciousness scientists, provide a suitable environment for the field to grow and develop sustainably. We conducted an online survey on people’s views regarding various aspects of the scientific study of consciousness as a field of (...) research. 249 participants completed the survey, among which 80% were in academia, and around 40% were experts in consciousness research. Topics covered include the progress made by the field, funding for consciousness research, job opportunities for consciousness researchers, and the scientific rigor of the work done by researchers in the field. The majority of respondents (78%) indicated that scientific research on consciousness has been making progress. However, most participants perceived obtaining funding and getting a job in the field of consciousness research as more difficult than in other subfields of neuroscience. Overall, work done in consciousness research was perceived to be less rigorous than other neuroscience subfields, but this perceived lack of rigor was not related to the perceived difficulty in finding jobs and obtaining funding. Lastly, we found that, overall, the global workspace theory was perceived to be the most promising (around 28%), while most non-expert researchers (around 22% of non-experts) found the integrated information theory (IIT) most promising. We believe the survey results provide an interesting picture of current opinions from scientists and researchers about the progresses made and the challenges faced by consciousness research as an independent field. They will inspire collective reflection on the future directions regarding funding and job opportunities for the field. (shrink)

SCHOFIELD I, TOLSON D and FLEMING V. Nursing Inquiry 2012; 19: 165–176 [Epub ahead of print]How nurses understand and care for older people with delirium in the acute hospital: a Critical Discourse AnalysisDelirium is a common presentation of deteriorating health in older people. It is potentially deleterious in terms of patient experience and clinical outcomes. Much of what is known about delirium is through positivist research, which forms the evidence base for disease‐based classification systems and clinical guidelines. There is (...) little systematic study of nurses’ day‐to‐day practice of nursing patients with delirium. The aim was to uncover the kinds of knowledge that informs nurses’ care and to explicate the basis of that knowledge. Critical Discourse Analysis is underpinned by the premise that powerful interests within society mediate how social practices are constructed. Links were made between the grammatical and lexical features of nurses’ language about care in interviews and naturalistic settings, and the healthcare context. Care focused on the continuous surveillance of patients with delirium by nurses themselves or vicariously through other patients, and containment. Nurses influenced by major discourses of risk reduction and safety, constructed patients with delirium as risk objects. The philosophy of person‐centred and dignified care advocated in nursing literature and government policy is an emerging discourse, though little evident in the data. The current dominant discourses on safety must give space to discourses of dignity and compassion. (shrink)
