The use of virtual humans holds the potential for interactive, automated interaction in domains such as remote communication, customer service, or public announcements. For signed language users, signing avatars could potentially provide accessible content by sharing information in the signer's preferred or native language. As the development of signing avatars has gained traction in recent years, researchers have come up with many different methods of creating signing avatars. The resulting avatars vary widely in their appearance, the naturalness of their movements, (...) and facial expressions—all of which may potentially impact users' acceptance of the avatars. We designed a study to test the effects of these intrinsic properties of different signing avatars while also examining the extent to which people's own language experiences change their responses to signing avatars. We created video stimuli showing individual signs produced by a live human signer, an avatar made using computer-synthesized animation, and an avatar made using high-fidelity motion capture. We surveyed 191 American Sign Language users, including Deaf, Hard-of-Hearing, and Hearing groups. Participants rated the three signers on multiple dimensions, which were then combined to form ratings of Attitudes, Impressions, Comprehension, and Naturalness. Analyses demonstrated that the Mocap avatar was rated significantly more positively than the CS avatar on all primary variables. Correlations revealed that signers who acquire sign language later in life are more accepting of and likely to have positive impressions of signing avatars. Finally, those who learned ASL earlier were more likely to give lower, more negative ratings to the CS avatar, but we did not see this association for the Mocap avatar or the Human signer. Together, these findings suggest that movement quality and appearance significantly impact users' ratings of signing avatars and show that signed language users with earlier age of ASL acquisition are the most sensitive to movement quality issues seen in computer-generated avatars. We suggest that future efforts to develop signing avatars consider retaining the fluid movement qualities integral to signed languages. (shrink)

An examination of David Hume's philosophy of religion that situates his conception "true religion" within the context of his overall science of human nature, his rejection of popular religion, and his Ciceronian influence"--Provided by publisher.

Marie-Aure´lie Bruno,1 Jan L Bernheim,2 Didier Ledoux,1 Fre´de´ric Pellas.

This reconsideration of Hume’s classic essay “Of Miracles” via the lens of American pragmatist ways of thinking about history and power shifts our attention from Hume’s epistemic concerns about the legitimacy of witnesses and testimony to his distaste for sacred history, his critical stance regarding the social force of revelation, and his disdain for religious authority. To view Hume’s essay both as an articulation of a critical philosophy of history and as an exercise in moral dynamism (social power or, authority, (...) is a result of epistemic transactions), is to intervene in both Hume studies and Contemporary Pragmatism.

Disorders of consciousness (DOC) raise profound scientific, clinical, ethical, and philosophical issues. Growing knowledge on fundamental principles of brain organization in healthy individuals offers new opportunities for a better understanding of residual brain function in DOCs. We here discuss new perspectives derived from a recently proposed scheme of brain organization underlying consciousness in healthy individuals. In this scheme, thalamo-cortical networks can be divided into two, often antagonistic, global systems: (i) a system of externally oriented, sensory-motor networks (the ‘‘extrinsic’’ system); and (...) (ii) a system of inward-oriented networks (the ‘‘intrinsic’’ or default system). According to this framework, four distinct mental states would be possible that could be relevant for understanding DOCs. In normal healthy volunteers and locked-in syndrome patients, a state of high functionality of both the extrinsic and intrinsic or default systems is expected — associated with full awareness of environment and self. In this case, mental imagery tasks combined with fMRI can be used to detect covert awareness in patients that are unable to communicate. According to the framework, two complementary states of system imbalance are also possible, in which one system is in a hyperfunctional state, while the other is hypoactive. Extrinsic system hyperfunction is expected to lead to a state of total sensory-motor ‘‘absorption’’ or ‘‘lost self.’’ In contrast, intrinsic or default system hyperfunction is expected to lead to a state of complete detachment from the external world. A state where both extrinsic and intrinsic systems are hypofunctional is predicted to lead to markedly impaired consciousness as seen in DOCs. Finally, we review the potential use of ultra-slow fluctuations in BOLD signal as a tool for assessing the functional integrity of extrinsic and intrinsic systems during ‘‘resting state’’ fMRI acquisitions..

Argues for the primacy of the phylogenetic system as the general reference system in biology. This book, first published in 1966, generated significant controversy and opened possibilities for evolutionary biology.

Microbes can influence host physiology and behavior in many ways. Here we review evidence suggesting that some microbes can contribute to host stress (and other microbes can contribute to increased resilience to stress). We explain how certain microbes, which we call “stress microbes,” can potentially benefit evolutionarily from inducing stress in a host, gaining access to host resources that can help fuel rapid microbial replication by increasing glucose levels in the blood, increasing intestinal permeability, and suppressing the immune system. Other (...) microbes, which we term “resilience microbes,” can potentially benefit from making hosts more resilient to stress. We hypothesize that “stress microbes” use a fast life history strategy involving greater host exploitation while “resilience microbes” use a slow life history strategy characterized by more aligned evolutionary interests with the host. In this paper, we review the evidence that microbes affect host stress and explain the evolutionary pressures that could lead microbes to manipulate host stress, discuss the physiological mechanisms that are known to be involved in both stress and microbial activity, and provide some testable predictions that follow from this hypothesis.

Purpose - The aim of this research was to investigate the effect of transformational leadership and transactional contingent reward as complementary, but distinct, forms of leadership on facets of organizational identification via the perception of innovation and goal organizational values. Design/methodology/approach – Three studies were carried out implementing either a measurement of mediation or experimental-causal-chain design to test for the hypothesized effects. Findings - The measurement of mediation study showed that transformational leadership had a positive direct and indirect effect, via (...) innovation value orientation, on cognitive identification, whereas transactional contingent reward was more strongly related to affective, rather than cognitive, identification, and goal orientation was a mediator of their link. The findings of the two experimental-causal-chain studies further supported the hypothesized effects. Transformational leadership was found to lead subordinates to perceive the culture as more innovative compared to transactional contingent reward, whereas transactional contingent reward led employees to perceive the culture as more goal, than innovation, oriented. Finally, innovation, compared to goal, value orientation increased cognitive identification, while goal orientation facilitated affective, rather than cognitive, identification. Implications - The practical implications involve the development of strategies organizations can apply, such as leadership training programs, to strengthen their ties with their employees, which, in turn, may have a positive impact on in-role, as well as extra-role, behaviors. Originality/Value – The originality of this research concerns the identification of distinct mechanisms explaining the effect of transformational leadership and transactional contingent reward on cognitive and affective identification applying an organizational culture perspective and a combination of measurement and causal mediation designs.

Orienting biases for speech may provide a foundation for language development. Although human infants show a bias for listening to speech from birth, the relation of a speech bias to later language development has not been established. Here, we examine whether infants' attention to speech directly predicts expressive vocabulary. Infants listened to speech or non-speech in a preferential listening procedure. Results show that infants' attention to speech at 12 months significantly predicted expressive vocabulary at 18 months, while indices of general (...) development did not. No predictive relationships were found for infants' attention to non-speech, or overall attention to sounds, suggesting that the relationship between speech and expressive vocabulary was not a function of infants' general attentiveness. Potentially ancient evolutionary perceptual capacities such as biases for conspecific vocalizations may provide a foundation for proficiency in formal systems such language, much like the approximate number sense may provide a foundation for formal mathematics.

Third Space, Hetero-Chronotopoi, Materialität – zwischenräumliche Strukturen als Analyseelemente machen raumzeitliche Merkmale vergangener und gegenwärtiger Gesellschaften und Untersuchungsgegenstände sichtbar. Der Band versammelt Beiträge verschiedener Disziplinen, deren Forschung von der Suche nach den jeweiligen Zwischenräumen wie ein roter Faden durchzogen ist. So wird ein Bogen gespannt von religiösen Zwischenräumen zu heterotopen Raum-Zeitlichkeiten als einer Spielart von Zwischenräumen bis hin zu zwischenräumlichen Materialitäten und Körperlichkeiten. Die Publikation zeichnet eine Entwicklung nach, die in den Erfurter Zwischenräume-Workshops mit je unterschiedlicher Schwerpunktsetzung zu „Zwischenräumen" begonnen (...) wurde und die sich im Aufgreifen und Anwenden etablierter und in der Entwicklung und dem Erproben neuer Analysekategorien auszeichnet. Die Ergebnisse der diskutierten Raumansätze sind innovativ und lassen jenseits bekannter Strukturen historische Zusammenhänge sichtbar werden. (shrink)

This article applies a critical femininities perspective to the concept of women’s leadership, interrogating the market-oriented instrumentalization of femininity. The author presents empirical research consisting of in-depth interviews conducted with young women leaders in European student organizations. These participants juggle complicity and subversion as they negotiate the divergent expectations of femininity and leadership through interpersonal interactions and sociocultural positionalities. In these narratives the themes of social responsibility, difference, femininity, culture and embodiment are interlaced. The analysis of findings complicates monolithic interpretations (...) of femininity by evidencing intra-categorical fracturing, multiplicity in locations and manifestations of femininities, conflicting attachments and affective relations to femininity, and broader geopolitical contextualization. This theoretically and practically challenges tropes of hegemonic femininity, and presents opportunities for resistance. On this basis the author argues for countering the feminist trouble of engaging with non-transgressive femininity from within strongly normative spaces in the development of critical femininity studies.

Drawing on a range of philosophical, anthropological and political theories, Athena Athanasiou offers a new way of thinking about agonistic performativity with its critical connections to national and gender politics and alongside the political intricacies of affectivity, courage and justice. Through an ethnographic account of the urban feminist and antinationalist movement Women in Black of Belgrade during the Yugoslav wars, she shows that we might understand their dissident politics of mourning as a means to refigure political life beyond sovereign (...) accounts of subjectivity and agency.

Smartphone use changes the landscape of social interactions, including introducing new social dilemmas to daily life. The challenge of putting down one's smartphone is an example of a classic coordination problem from game theory: the stag hunt game. In a stag hunt game, there are two possible coordination points, one that involves big payoffs for both partners (e.g., working together to hunt large game like stag) and one that involves smaller payoffs for both partners (e.g., individually hunting small game like (...) rabbits) but is safer because it does not require that your partner choose that option as well. This is similar to the challenges of putting down smartphones to have a face‐to‐face interaction: you and your interaction partner might both prefer the higher payoff option of having a face‐to‐face interaction, but neither of you wants to put down your phone and risk not having anything to do in the meantime. It is also discussed how new technological innovations are changing the payoffs of face‐to‐face conversation versus side‐by‐side smartphone scrolling. Insights that come from applying game theory to this “social media dilemma” are discussed here and potential solutions that come out of a game theoretic analysis are offered.

Dispossession describes the condition of those who have lost land, citizenship, property, and a broader belonging to the world. This thought-provoking book seeks to elaborate our understanding of dispossession outside of the conventional logic of possession, a hallmark of capitalism, liberalism, and humanism. Can dispossession simultaneously characterize political responses and opposition to the disenfranchisement associated with unjust dispossession of land, economic and political power, and basic conditions for living? In the context of neoliberal expropriation of labor and livelihood, dispossession opens (...) up a performative condition of being both affected by injustice and prompted to act. From the uprisings in the Middle East and North Africa to the anti-neoliberal gatherings at Puerta del Sol, Syntagma and Zucchotti Park, an alternative political and affective economy of bodies in public is being formed. Bodies on the street are precarious - exposed to police force, they are also standing for, and opposing, their dispossession. These bodies insist upon their collective standing, organize themselves without and against hierarchy, and refuse to become disposable: they demand regard. This book interrogates the agonistic and open-ended corporeality and conviviality of the crowd as it assembles in cities to protest political and economic dispossession through a performative dispossession of the sovereign subject and its propriety.

Ethics in the anthropocene -- Atmospheric powers: climate change and moral incompetence -- Christian ethics and unprecedented problems -- Global ethics: moral pluralism and planetary problems -- Sustainability science and the ethics of wicked problems -- Toxic wombs and the ecology of justice -- Impoverishment and the economy of desire -- Intergenerational risk and the future of love -- Sustaining grace.

Ethicists regularly turn to virtue in order to negotiate features of climate change that seem to overwhelm moral agency. Appeals to virtue in climate ethics differ by how they connect individual flourishing with collective responsibilities and by how they interpret Anthropocene relations. Differences between accounts of climate virtue help critique proposals to reframe global ecological problems in terms of resilience and planetary stewardship, the intelligibility of which depends on connecting what would be good for the species with what would be (...) good for an individual life. A pragmatic way of establishing that connection may need a strong role for respect of nature. (shrink)

Despite acknowledgment that performance failure among new salespeople is a prevalent issue for organizations, researchers do not fully understand the consequences of repetitive periods of failure on new salespeople’s unethical selling behaviors. Further, little is known about how a sales force’s reward structure and managerial attempts to intervene following failure affect new salespeople’s behavior. Combining an experiment with longitudinal growth models, we show that repetitive periods of failure increase unethical behaviors, and interventions intended to remind the salesperson to behave in (...) the customer’s best interests attenuate this effect under a non-contingent reward structure. However, counter to managerial assumptions, under a contingent reward structure these customer-oriented interventions actually backfire by amplifying the original relationship between repetitive failure and unethical behaviors. The results have potentially important managerial implications for those who manage new salespeople learning how to sell or during other failure-prone periods. (shrink)

From an informal group of a dozen faculty and graduate students at Temple University, the Jean Piaget Society grew in seven years to 500 members who have interests in the application of genetic epistemology to their own disciplines and professions. At the outset Piaget endorsed the concept of a society which bore his name and presented a major address on equilibration at the society's first symposium in May, 1971. Had he not done so the society would no doubt have remained (...) a small parochial group, like so many others throughout the country, interested in Piaget and his theory. With the encouragement of Genevans and the leadership of its first four presidents, Lois Macomber, Barbara Press eisen, Marilyn Appel, and John Mickelson, the society undertook a number of programs to collect and disseminate the results of scholarly work in genetic epistemology. Particular emphasis was placed upon applications of Piaget's theory to developmental psychology, philos ophy, and education. One of these programs was the publication of an annual series on the development of knowing, of which this volume is the first. In 1973, the society asked Hans Furth with the assistance of Willis Overton and Jeanette Gallagher to initiate and plan a series of yearbooks with the result that in addition to this volume, a second volume on education was commissioned, and a third one on the decalage issue was planned.

The fields of environmental ethics and of religion and ecology have been shaped by Lynn White Jr.'s thesis that the roots of ecological crisis lie in religious cosmology. Independent critical movements in both fields, however, now question this methodological legacy and argue for alternative ways of inquiry. For religious ethics, the twin controversies cast doubt on prevailing ways of connecting environmental problems to religious deliberations because the criticisms raise questions about what counts as an environmental problem, how religious traditions change, (...) and whether ethicists should approach problems and traditions with reformist commitments. This article examines the critiques of White's legacy and presents a pluralist alternative that focuses religious ethics on the contextual strategies produced by moral communities as they confront environmental problems.
