Early humans formed language units consisting of global and discrete dimensions of semiosis in dynamic opposition, or ‘growth points.’ At some point, gestures gained the power to orchestrate actions, manual and vocal, with significances other than those of the actions themselves, giving rise to cognition framed in dual terms. However, our proposal emphasizes natural selection of joint gesture-speech, not ‘gesture-first’ in language origin.

Conducting research with vulnerable populations involves careful attention to the interests of individuals. Although it is generally understood that informed consent is a necessary prerequisite to research participation, it is less clear how to proceed when potential research participants lack the capacity to provide this informed consent. The rationale for assessing the assent or dissent of vulnerable individuals and obtaining informed consent by authorized representatives is discussed. Practical guidelines for recruitment of and data collection from people in the middle or (...) late stage of dementia are proposed. These guidelines were used by research assistants in a minimal risk study. (shrink)

The Tuskegee Syphilis Study is often cited as a major reason for low research participation rates among racial/ethnic minorities. We use data from a random-digit-dial telephone survey of 510 African Americans and 253 Latinos drawn from low income Los Angeles neighborhoods to investigate associations between knowledge of the study and endorsement of HIV/aids conspiracy theories. Results indicate African Americans were significantly more likely than Latinos to endorse HIV/aids conspiracy theories and were more aware of the study. Nevertheless, few Americans and (...) Latinos had ever heard of Syphilis Study suggesting that awareness is not a major factor in low participation rates. (shrink)

Did protolanguage users use discrete words that referred to objects, actions, locations, etc., and then, at some point, combine them; or on the contrary did they have words that globally indexed whole semantic complexes, and then come to divide them? Our answer is: early humans were forming language units consisting of global and discrete dimensions of semiosis in dynamic opposition. These units of thinking-for-speaking, or ‘growth points’ (GPs) were, jointly, analog imagery (visuo-spatio-motoric) and categorically-contrastive (-emic) linguistic encodings. This discrete-global duality (...) was a new mode of embodied cognition that enabled thinking and acting in new ways: the dawn of protolanguage. Where did this mode of cognition come from? We have some suggestions based on the hypothesis that gestures gained the power to orchestrate actions, manual and vocal, with significances other than those of the actions themselves, giving rise to cognition framed in the proposed dual terms. Note, however, our proposal is not one of the ‘gesture-first’ theories of language origins. Such theories predict what did not evolve: a language of pantomime; rather than what did evolve: an integrated system of synchronized gestures and spoken forms. GP theory is an account of the cognition underlying such an integrated system. A scenario for the evolutionary selection of this cognitive mode is ‘Mead’s Loop’, a model in which one’s cognition is enriched by one’s own gestures, insofar as they are objects in social interactions.

This is a description of an avian-shaped feature that rests below a network of cellular structures found on a mound within the Argyre Basin of Mars in Mars Global Surveyor image M14-02185, acquired on April 30, 2000, and released to the public on April 4, 2001. The area examined is located near 48.0° South, 55.1° West. The formation is approximately 2,400 meters long from the tip of its beak to the tip of its farthest tail feather. There is a minimum (...) of six different variations in appearance of the surface material over this small area. Utilizing the public targeting request form provided on the Mars Global Surveyor (MGS) website, co-author Miller secured a second image of the area that was obtained on July 3, 2006, showing this feature under different conditions S20-00165. The new image was then released to the public on August 11, 2006. A third image of the formation identified as MGS S13-01480 was acquired on December 15, 2005, and although officially processed on June 20, 2006, it was not made available to the public until August 22, 2009, on NASA’s Planetary Data System (PDS) website. All three of the MGS images reveal defining aspects of this avian feature, including a head, beak, body, eye, leg, foot, toes, wing, and feathers. When taken together, these components induce the visual impression of an avian-shaped formation that exhibits a unique set of proportional features. Adjoining this formation is a composite of complex cellular features that form a compartmentalized infrastructure. The three authors who are veterinarians provide a critical analysis of the avian features, and the geologist and geoscientist authors examine natural mechanisms that could contribute to the formation of this feature. An extensive search of comparable regions within and beyond the area of the Argyre Basin was conducted. A list of these sites is provided, and terrestrial comparisons are also offered. (shrink)

After decades of marginalization in the secularized twentieth-century academy, moral education has enjoyed a recent resurgence in American higher education, with the establishment of more than 100 ethics centers and programs on campuses across the country. Yet the idea that the university has a civic responsibility to teach its undergraduate students ethics and morality has been met with skepticism, suspicion, and even outright rejection from both inside and outside the academy. In this collection, renowned scholars of philosophy, politics, and religion (...) debate the role of ethics in the university, investigating whether universities should proactively cultivate morality and ethics, what teaching ethics entails, and what moral education should accomplish. The essays quickly open up to broader questions regarding the very purpose of a university education in modern society. Editors Elizabeth Kiss and J. Peter Euben survey the history of ethics in higher education, then engage with provocative recent writings by Stanley Fish in which he argues that universities should not be involved in moral education. Stanley Hauerwas responds, offering a theological perspective on the university’s purpose. Contributors look at the place of politics in moral education; suggest that increasingly diverse, multicultural student bodies are resources for the teaching of ethics; and show how the debate over civic education in public grade-schools provides valuable lessons for higher education. Others reflect on the virtues and character traits that a moral education should foster in students—such as honesty, tolerance, and integrity—and the ways that ethical training formally and informally happens on campuses today, from the classroom to the basketball court. _Debating Moral Education_ is a critical contribution to the ongoing discussion of the role and evolution of ethics education in the modern liberal arts university. _Contributors_.

In lieu of an abstract, here is a brief excerpt of the content:Form and Discontent*Rosmarie Waldrop (bio)1. Composition as ExplanationIn the beginning there is Gertrude Stein, who says in “Composition as Explanation”: “Everything is the same except composition and as the composition is different and always going to be different everything is not the same” [520].I could also say, in the beginning is Aristotle: “the fable is simply this, the combination of the incidents” [1460].2. A Look AroundThe forms that have (...) been striking me as “wild” have tended to be Steinian in this sense of stressing the horizontal, the axis of composition. I’m most struck by 3 tendencies: one is literally spatial composition, e.g. Susan Howe’s work; another, an emphasis on discontinuity, leaps on the level of syntax, of logic, of grammar. Breaks that do not immediately fold back into a smooth unity and may occur in mid-sentence:I was on my way from Carthage, it was night. It is not wax I am scorching was dead about her with knots.—Norma Cole, MarsI hide behind a category by misbehaving.—Carla Harryman, Under the BridgeLoop conceived in a line, the spine with its regions, reasons. On another, sweaters hang by the wrist to dry. The list is sweet. You lie. The eye is met by the season.—Ron Silliman, ParadiseYou took my temperature which I had meant to save for a more difficult day.—Rosmarie Waldrop, The Reproduction of ProfilesWent out so I’d take the car and a whole system of banking and money is based on a hierarchy.—Leslie Scalapino, Considering How Exaggerated the Music IsROAST POTATOESRoast Potatoes for.—Gertrude Stein, “Tender Buttons”Or, a subtler example, Mei-mei Berssenbrugge’s almost unnoticeable shifts from one grammatical structure into another: [End Page 54]Never mind if he calls, the places you get through inwardness take time, and to drift down to the shore of the island, you know by the sand moving, even the coarse sand here It’s hard to say if you can even stand up, there....[13]The third tendency is mathematical. There is a lot of counting. Not stresses, not even syllables—I’m not considering that most unimaginative bunch, the new formalists—but words per line, sentences per paragraph. You all know about Ron Silliman’s love for the Fibonacci number series, or Lyn Hejinian’s My Life, which began with 37 sections of 37 sentences each. When she published a second edition at age 45, she added 8 sentences to each section plus 8 new sections.Jacques Roubaud: “No ideas but in numbers” [291].Then, in a somewhat more remote way, a number of people use ideas of permutation. For example, Jackson Mac Low’s 4 Trains, of which I will quote the first two stanzas:Train rule atom intricate nitrogen. Rule unusual leotard entropy. Atom train ostrich might. Intricate nitrogen train rule intricate casual atom train entropy. Nitrogen intricate train rule ostrich genealogy entropy nitrogen.Rule unusual leotard entropy. Unusual nitrogen unusual social unusual atom leotard. Leotard entropy ostrich train atom rule dies. Entropy nitrogen train rule ostrich pope yearly.[7]As Zukofsky puts it: “[Thus] poetry may be defined as an order of words that as movement and tone (rhythm and pitch) approaches in varying degrees the wordless art of music as a kind of mathematical limit” [27].All these examples draw attention to arrangement, composition. They all listen to language. I once wrote:I don’t even have thoughts, I say, I have methods that make language think, take over and me by the hand. Into sense or offense, syntax stretched across rules, relations of force, fluid the dip of the plumb line, the pull of eyes.... No beginnings.

Forthright and wryly humorous, philosopher Susan Haack deploys her penetrating analytic skills on some of the most highly charged cultural and social debates of recent years. Relativism, multiculturalism, feminism, affirmative action, pragmatisms old and new, science, literature, the future of the academy and of philosophy itself—all come under her keen scrutiny in Manifesto of a Passionate Moderate.

Summary Analogue models are actual physical setups used to model something else. They are especially useful when what we wish to investigate is difficult to observe or experiment upon due to size or distance in space or time: for example, if the thing we wish to investigate is too large, too far away, takes place on a time scale that is too long, does not yet exist or has ceased to exist. The range and variety of analogue models is too (...) extensive to attempt a survey. In this article, I describe and discuss several different analogue model experiments, the results of those model experiments, and the basis for constructing them and interpreting their results. Examples of analogue models for surface waves in lakes, for earthquakes and volcanoes in geophysics, and for black holes in general relativity, are described, with a focus on examining the bases for claims that these analogues are appropriate analogues of what they are used to investigate. A table showing three different kinds of bases for reasoning using analogue models is provided. Finally, it is shown how the examples in this article counter three common misconceptions about the use of analogue models in physics. (shrink)

Crowdsourcing has attracted increasing attention as a means to enlist online participants in organisational activities. In this paper, we examine crowdsourcing from the perspective of its ethical use in the support of open innovation taking a broader system view of its use. Crowdsourcing has the potential to improve access to knowledge, skills, and creativity in a cost-effective manner but raises a number of ethical dilemmas. The paper discusses the ethical issues related to knowledge exchange, economics, and relational aspects of crowdsourcing. (...) A guiding framework drawn from the ethics literature is proposed to guide the ethical use of crowdsourcing. A major problem is that crowdsourcing is viewed in a piecemeal fashion and separate from other organisational processes. The trend for organisations to be more digitally collaborative is explored in relation to the need for greater awareness of crowdsourcing implications. (shrink)

The concept of similar systems arose in physics, and appears to have originated with Newton in the seventeenth century. This chapter provides a critical history of the concept of physically similar systems, the twentieth century concept into which it developed. The concept was used in the nineteenth century in various fields of engineering, theoretical physics and theoretical and experimental hydrodynamics. In 1914, it was articulated in terms of ideas developed in the eighteenth century and used in nineteenth century mathematics and (...) mechanics: equations, functions and dimensional analysis. The terminology physically similar systems was proposed for this new characterization of similar systems by the physicist Edgar Buckingham. Related work by Vaschy, Bertrand, and Riabouchinsky had appeared by then. The concept is very powerful in studying physical phenomena both theoretically and experimentally. As it is not currently part of the core curricula of STEM disciplines or philosophy of science, it is not as well known as it ought to be. (shrink)

Within this paper, we discuss Moral Distress Reflective Debriefs as a promising approach to address and mitigate moral distress experienced by healthcare professionals. We briefly review the empirical and theoretical literature on critical incident stress debriefing and psychological debriefing to highlight the potential benefits of this modality. We then describe the approach that we take to facilitating reflective group discussions in response to morally distressing patient cases (“Moral Distress Reflective Debriefs”). We discuss how the debriefing literature and other clinical ethics (...) activities influenced the development of our approach. In particular, we focus on the role of the clinical ethicist as a facilitator with particular emphasis on encouraging perspective-taking and nurturing ethical attunement in a supportive manner. We suggest that this approach reduces the narrowing effects of frustration and anger that are often reported when individuals experience moral-constraint distress. Finally, we provide an example of Moral Distress Reflective Debriefs, elucidating how this supportive process complements ethics consultation and can mitigate the negative effects of moral distress.

Philosophising, as Spinoza conceives it, is the project of learning to live joyfully. This in turn is a matter of learning to live together, and the most obvious test of philosophical insight is our capacity to sustain a harmonious way of life. Susan James defends this interpretation and explores Spinoza's influence on contemporary debates.

Abstract: Recent experimental research on the 'Knobe effect' suggests, somewhat surprisingly, that there is a bi-directional relation between attributions of intentional action and evaluative considerations. We defend a novel account of this phenomenon that exploits two factors: (i) an intuitive asymmetry in judgments of responsibility (e.g. praise/blame) and (ii) the fact that intentionality commonly connects the evaluative status of actions to the responsibility of actors. We present the results of several new studies that provide empirical evidence in support of this (...) account while disconfirming various currently prominent alternative accounts. We end by discussing some implications of this account for folk psychology. (shrink)

Leading scholars continue the debate over whether consciousness causes behavior or plays no functional role in it, discussing the question in terms of neuroscience, philosophy, law, and public policy.

This introductory chapter explains the coverage of this book, which is about animal rationality and mental processing in animals. This book discusses the theoretical issues and distinctions that bear on attributions of rationality to animals and draws some contrasts between rationality and certain other traits of animals to determine the relationships between them. It explores the relations between behaviour and the processes that explain behaviour, and the senses in which animal behaviour might be rational in virtue of features other than (...) classical reasoning processes on the human model. -/- .

This article reflects on the work of feminist bioethicists over the past ten years, reviewing how effective feminists have been in using relational theory to reorient bioethics and where we hope it will go from here. Feminist bioethicists have made significant achievements using relational theory to shape the notion of autonomy, bringing to light the relevance of patients' social circumstances and where they are situated within systems of privilege and oppression. But there is much work to be done to reorient (...) bioethics so that it is capable of addressing some current public health challenges. We argue that relational theory holds promise for beginning this work. (shrink)

There is growing concern that a global economic system fueled predominately by financial incentives may not maximize human flourishing and social welfare externalities. If so, this presents a challenge of how to get economic actors to adopt a more virtuous motivational mindset. Relying on historical, psychological, and philosophical research, we show how such a mindset can be instilled. First, we demonstrate that historically, financial self-interest has never in fact been the only guiding motive behind free markets, but that markets themselves (...) are representations of our individual and collective moral identities. Building on this understanding, we review the research on how economic incentives crowd out virtue-oriented concerns. We then introduce the concept of moral self-awareness (MSA), an evolving mindset informed by reflection on moral identity, namely what one’s actions say about oneself given the impacts on others or society that one’s action may effect. MSA comprises three fundamental aspects of virtue-oriented reasoning: pride, shame, and guilt. Finally, we offer a four-stage model anchored in systems theory, yielding ever more refined motivating strategies for maximizing human flourishing and social welfare externalities. (shrink)

I defend the view that we should not overintellectualize the mind. Nonhuman animals can occupy islands of practical rationality: they can have contextbound reasons for action even though they lack full conceptual abilities. Holism and the possibility of mistake are required for such reasons to be the agent's reasons, but these requirements can be met in the absence of inferential promiscuity. Empirical work with animals is used to illustrate the possibility that reasons for action could be bound to symbolic or (...) social contexts, and connections are made to simulationist accounts of cognitive skills.

Throughout history there have been people who say it is all illusion. I think they may be right. But if they are right what could this mean? If you just say "It's all an illusion" this gets you nowhere - except that a whole lot of other questions appear.

_ Source: _Page Count 32 In this paper we first set the stage with a brief overview of the tangled history of humility in theology and philosophy—beginning with its treatment in the Bible and ending with the more recent work that has been done in contemporary philosophy. Our two-fold goal at this early stage of the paper is to explore some of the different accounts of humility that have traditionally been developed and highlight some of the key debates in the (...) current literature. Next, we present the findings from several studies we recently conducted in an effort to explore people’s intuitions and beliefs about humility as well as their experiences with being humble. Finally, we discuss the relevance of our findings to the ongoing philosophical debates about humility—suggesting that while some varieties of humility are problematic, other varieties of humility are certainly worth wanting.

This is a study of the central questions of explanation in the social sciences, and a defence of 'holism' against 'individualism'. In the first half of the book Susan James sets out very clearly the philosophical background to this controversy. She locates its source not at the analytical level at which most of the debate is usually conducted but at a more fundamental, moral level, in different conceptions of the human individual. In the second half of the book she (...) examines critically three case studies of holistic approaches - Althusser, Poulantzas and the Annales historians - and progressively refines our sense of the strengths and deficiencies of their programmes. She ends by arguing for a form of concessive holism, which offers some accommodation to liberal conceptions of individual autonomy but continues to emphasise the explanatory importance of social regularities and environments.

On a literal reading of `Computing Machinery and Intelligence'', Alan Turing presented not one, but two, practical tests to replace the question `Can machines think?'' He presented them as equivalent. I show here that the first test described in that much-discussed paper is in fact not equivalent to the second one, which has since become known as `the Turing Test''. The two tests can yield different results; it is the first, neglected test that provides the more appropriate indication of intelligence. (...) This is because the features of intelligence upon which it relies are resourcefulness and a critical attitude to one''s habitual responses; thus the test''s applicablity is not restricted to any particular species, nor does it presume any particular capacities. This is more appropriate because the question under consideration is what would count as machine intelligence. The first test realizes a possibility that philosophers have overlooked: a test that uses a human''s linguistic performance in setting an empirical test of intelligence, but does not make behavioral similarity to that performance the criterion of intelligence. Consequently, the first test is immune to many of the philosophical criticisms on the basis of which the (so-called) `Turing Test'' has been dismissed. (shrink)

This paper argues that the various approaches to ethics that bioethicists rely on are not adequate to provide effective moral guidance in how to avoid a series of looming human catastrophes (associated with such threats as environmental degradation, war, extreme poverty, and pandemics). It proposes development of a new approach to ethics, dubbed public ethics, that simultaneously investigates moral responsibilities at multiple levels of human organization from the individual to international bodies. It argues that feminist relational theory can provide guidance (...) to development of this new type of ethics, and it warns against obstacles bioethicists face in its pursuit. (shrink)

This book is a critically informed challenge to the traditional histories of rhetoric and to the current emphasis on Aristotle and Plato as the most significant classical voices in rhetoric. In it, Susan C. Jarratt argues that the first sophists—a diverse group of traveling intellectuals in the fifth century B.C.—should be given a more prominent place in the study of rhetoric and composition. Rereading the ancient sophists, she creates a new lens through which to see contemporary social issues, including (...) the orality/literacy debate, feminist writing, deconstruction, and writing pedagogy. The sophists’ pleasure in the play of language, their focus on historical contin-gency, and the centrality of their teaching for democratic practice were sufficiently threatening to their successors Plato and Aristotle that both sought to bury the sophists under philosophical theories of language. The censure of Plato and Aris-totle set a pattern for historical views of the sophists for centuries. Following Hegel and Nietzsche, Jarratt breaks the pattern, finding in the sophists a more progressive charter for teachers and scholars of reading and writing, as well as for those in the adjacent disciplines of literary criticism and theory, education, speech communication, and ancient history. In tracing the historical interpretations of sophistic rhetoric, Jarratt suggests that the sophists themselves provide the outlines of an alternative to history-writing as the discovery and recounting of a set of stable facts. She sees sophistic use of narrative in argument as a challenge to a simple division between orality and literacy, current discussions of which virtually ignore the sophists. Outlining similarities between _écriture féminine _and sophistic style, Jarratt shows that contemporary feminisms have more in common with sophists than just a style; they share a rhetorical basis for deployment of theory in political action. In her final chapter, Jarratt takes issue with accounts of sophistic pedagogy focusing on technique and the development of the individual. She argues that, despite its employment by powerful demagogues, sophistic pedagogy offers a resource for today’s teachers interested in encouraging minority voices of resistance through language study as the practice of democracy.

Subjects estimated the time of intentions to perform an action, of the action itself, or of an auditory effect of the action. A perceptual attraction or binding effect occurred between actions and the effects that followed them. Judgements of intentions did not show this binding, suggesting they are represented independently of actions and their effects. In additional unpredictable judgement conditions, subjects were instructed only after each trial which of these events to judge, thus discouraging focussed attention to a specific event. (...) Stronger binding effects were found, with intention, action and effect fusing to a single central point in time. In a control task, subjects reported the time of the first or second tone in sequence. Tone sequences showed no binding at all when subjects knew in advance which tone to judge, but showed the same fusion as actions when the event to be judged was not predictable. Binding of actions and effects, but not of tone sequences, occurs pre-attentively, and automatically. The data are consistent with a reconstructive process, implemented after actions, which generates a coherent sense of agency. However, this process should only be triggered only when our actions make it appropriate. We suggest that this mechanism is triggered in advance by efferent processing. This conclusion was supported by a further study in deafferented subject IW. This subject showed the normal binding of a tone towards an action, although his experience of the action was of pre-motor, rather than peripheral origin. The experience of intentional action involves an interplay between pre-motor and reconstructive processes. (shrink)

A nativist moral psychology, modeled on the successes of theoretical linguistics, provides the best framework for explaining the acquisition of moral capacities and the diversity of moral judgment across the species.

The principles (...) and parameters approach predicts moral diversity, but does not entail moral relativism. (shrink)

Background Encounters of moral distress have long-term consequences on healthcare workers’ physical and mental health, leading to job dissatisfaction, reduced patient care, and high levels of burnout, exhaustion, and intentions to quit. Yet, research on approaches to ameliorate moral distress across the health workforce is limited. Research Objective The aim of our study was to qualitatively explore multi-professional perspectives of healthcare social workers, chaplains, and patient liaisons on ways to reduce moral distress and heighten well-being at a southern U.S. academic (...) medical center. Participants & Research Context Purposive sampling and chain-referral methods assisted with recruitment through hospital listservs, staff meetings, and newsletters. Interested participants contacted the principal investigator and all interviews were conducted in-person. Consent was attained prior to interviews. All interviews were recorded and transcribed verbatim. Research Design Directed content analysis was used to deductively organize codes and to develop themes in conjunction with the National Academy of Medicine’s National Plan for Health Workforce Well-Being. Rigor was attained through peer-debriefing, data triangulation methods, and frequent research team meetings. Ethical Considerations Ethics approval was obtained from the university and medical center institutional review boards. Findings Themes demonstrate that rather than offering interventions in the aftermath of moral distress, multilevel daily practices ought to be considered that pre-emptively identify and reduce morally distressing encounters through (1) the care team, (2) management and leadership, and (3) the health care industry. Strategies include interdisciplinary decision-making, trusting managerial relationships, and organizational policies and practices that explicitly invest in mental health promotion and diverse leadership opportunities. Conclusion Moral distress interventions ought to target short-term stress reactions while also addressing the long-term impacts of moral residue. Health systems must financially commit to an ethical workplace culture that explicitly values mental health and well-being. (shrink)

A beneficial effect of gesture on learning has been demonstrated in multiple domains, including mathematics, science, and foreign language vocabulary. However, because gesture is known to co‐vary with other non‐verbal behaviors, including eye gaze and prosody along with face, lip, and body movements, it is possible the beneficial effect of gesture is instead attributable to these other behaviors. We used a computer‐generated animated pedagogical agent to control both verbal and non‐verbal behavior. Children viewed lessons on mathematical equivalence in which an (...) avatar either gestured or did not gesture, while eye gaze, head position, and lip movements remained identical across gesture conditions. Children who observed the gesturing avatar learned more, and they solved problems more quickly. Moreover, those children who learned were more likely to transfer and generalize their knowledge. These findings provide converging evidence that gesture facilitates math learning, and they reveal the potential for using technology to study non‐verbal behavior in controlled experiments. (shrink)
