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)

Bei transzendenten Erfahrungen treten Aspekte und Dimensionen der vertrauten Wirklichkeit hervor, die normalerweise verborgen sind. Gewohnte Deutungsmuster und Erklarungskategorien versagen. Kognitive Spannungen sind die Folge. Das Bedurfnis nach ihrer Losung fuhrt oft zu vorschnellen Interpretationen und Erklarungen oder gar zur apriorischen Abwertung und Ignorierung transzendenter Erfahrungen. Sorgfaltige und umsichtige wissenschaftliche Studien sind daher immer noch ein Desiderat. Die Beitrage basieren auf einer Ringvorlesung an der Universitat Basel. Sie thematisieren an einschlagigen Beispielen die Phanomenologie transzendenter Erfahrungen, ihre biographischen Wirkungen, ihr Zusammenspiel (...) mit kunstlerischem Schaffen und Erleben, die Schwierigkeit ihrer Deutung und Beurteilung und ihre Abwertung und Pathologisierung durch Aufklarung und Wissenschaft.

In _Wild Blue Media_, Melody Jue destabilizes terrestrial-based ways of knowing and reorients our perception of the world by considering the ocean itself as a media environment—a place where the weight and opacity of seawater transforms how information is created, stored, transmitted, and perceived. By recentering media theory on and under the sea, Jue calls attention to the differences between perceptual environments and how we think within and through them as embodied observers. In doing so, she provides media studies (...) with alternatives to familiar theoretical frameworks, thereby challenging scholars to navigate unfamiliar oceanic conditions of orientation, materiality, and saturation. Jue not only examines media about the ocean—science fiction narratives, documentary films, ocean data visualizations, animal communication methods, and underwater art—but reexamines media _through_ the ocean, submerging media theory underwater to estrange it from terrestrial habits of perception while reframing our understanding of mediation, objectivity, and metaphor.

This study investigates the procedural learning, retention, and reactivation of temporal sensorimotor sequences in children with and without developmental coordination disorder. Twenty typically-developing children and 12 children with DCD took part in this study. The children were required to tap on a keyboard, synchronizing with auditory or visual stimuli presented as an isochronous temporal sequence, and practice non-isochronous temporal sequences to memorize them. Immediate and delayed retention of the audio-motor and visuo-motor non-isochronous sequences were tested by removing auditory or visual (...) stimuli immediately after practice and after a delay of 2 h. A reactivation test involved reintroducing the auditory and visual stimuli after the delayed recall. Data were computed via circular analyses to obtain asynchrony, the stability of synchronization and errors. Firstly, an overall deficit in synchronization with both auditory and visual isochronous stimuli was observed in DCD children compared to TD children. During practice, further improvements were found for the audio-motor non-isochronous sequence compared to the visuo-motor non-isochronous sequence in both TD children and children with DCD. However, a drastic increase in errors occurred in children with DCD during immediate retention as soon as the auditory stimuli were removed. Reintroducing auditory stimuli decreased errors in the audio-motor sequence for children with DCD. Such changes were not seen for the visuo-motor non-isochronous sequence, which was equally learned, retained and reactivated in DCD and TD children. All these results suggest that TD children benefit from both auditory and visual stimuli to memorize the sequence, whereas children with DCD seem to present a deficit in integrating an audio-motor sequence in their memory. The immediate effect of reactivation suggests a specific dependency on auditory information in DCD. Contrary to the audio-motor sequence, the visuo-motor sequence was both learned and retained in children with DCD. This suggests that visual stimuli could be the best information for memorizing a temporal sequence in DCD. All these results are discussed in terms of a specific audio-motor coupling deficit in DCD.

A central goal of typological research is to characterize linguistic features in terms of both their functional role and their fit to social and cognitive systems. One long-standing puzzle concerns why certain languages employ grammatical gender. In an information theoretic analysis of German noun classification, Dye, Milin, Futrell, and Ramscar enumerated a number of important processing advantages gender confers. Yet this raises a further puzzle: If gender systems are so beneficial to processing, what does this mean for languages that make (...) do without them? Here, we compare the communicative function of gender marking in German to that of prenominal adjectives in English, finding that despite their differences, both systems act to efficiently smooth information over discourse, making nouns more equally predictable in context. We examine why evolutionary pressures may favor one system over another and discuss the implications for compositional accounts of meaning and Gricean principles of communication. (shrink)

Background:At a time when British nursing has been under scrutiny for an apparent lack of compassion in education and practice, this paper based offers a perspective on the notions of vocation and altruism in nursing.Objectives:To understand the vocational and altruistic motivations of nurses through the application of Pierre Bourdieu's concepts of ‘symbolic capital’, ‘field’ and ‘habitus’ through a long interview with nurse respondents.Research design:A reflexive qualitative study was undertaken using the long interview. A thematic analysis of the data, using a (...) qualitative data software package for analysis, was undertaken. The ideas of Pierre Bourdieu (Habitus, Capital and Field) were used to analyse and explain the content of community nurses' ‘talk’.Participants:Twelve Community Nurses working in a variety of local primary care settings volunteered to participate in the study. It was a self-selecting convenience sample of nurses responding to an invitation to be interviewed.Research context:A study in support of a doctoral thesis conducted within NHS primary care settings with registered nurses.Ethical considerations:The key considerations for this study were to be mindful of the possibility of emotional harm or distress being caused to the respondents during the retelling of their experiences. It was also essential to ensure that the locations or names of patients or staff (if discussed) were anonymised. Ethical approval was sought and granted by both the Local NHS Primary Care and the University Ethics committees before the study commenced.Findings:The nurse respondents had highly individual and at times contradictory views on their motivations to nurse including their views on vocation and altruism in nursing careers.Discussion:Bourdieu's ideas apply well to the nursing context and provided a useful theoretical framework to explore the social and cultural influences on nursing careers. Gender is important consideration in all aspects of nursing but class and educational experience is an important dimension in the stories nurses tell.Conclusion:The culturally determined experiences of these nurses in practice offer an authentic and realistic insight into the complex motives and predispositions of community nurses. This paper argues that nurse motivations whether vocational or altruistic, are better understood as culturally, rather than spiritually, driven. (shrink)

In this chapter, we will discuss three key ethical issues related to data collected in stakeholder-engaged research: (1) data ownership, (2) deciding how data are used, and (3) deciding what is published. We begin with the legal and regulatory policies of universities and sponsors around data ownership and data sharing. We then discuss the role of principal investigator(s) in a study and/or partnership leaders as data stewards for the development and implementation of partnership practices for data decision-making. We examine the (...) implications of funding and timing since many decisions related to data use and sharing often happen after the project has ended. Finally, we discuss the roles and responsibilities of different stakeholders (e.g., funder, researcher, and nonacademic partner) and offer lessons to be learned and resources for partnerships.

To what extent do we pay attention to the text and images that cover our hospital walls and do we offer any critique either as professionals or service users? In the past we might have expected to see functional or helpful instructions about where to go (or not to go) and in more well‐endowed buildings, perhaps we would see some works of art, sculpture, stained glass even, with the intention to encourage, distract or even forewarn us. However, it is now (...) common in UK hospitals, for wall space to be used as a portal for a range of institutional political messages, that convey information about everything from its own values, behaviours to advertisements for products and services to requirements for rule following. Michel Foucault's ideas about Heterotopic space can help us to see that hospitals tend to fall (awkwardly) between being a public and personal health care space, and this is a possible explanation for the confused material culture and messages that are shared there. This paper draws on ethnographic methods to reflect on personal experience in order to offer a critique of the contemporary political discourse which has become 'literally' written onto our hospital walls.

Past research shows that the bilingual experience may enhance cognitive executive function. In this experiment, we evaluated cognitive control in bilinguals relative to monolinguals by using a dimensional overlap model to predict performance in a task composed of Stroop and Simon stimuli. A group of 24 Spanish monolinguals and 24 bilinguals with differing first languages and all having Spanish as a second language did a picture naming task and a task composed of Stroop and Simon stimuli, where the effect of (...) different overlap conditions between stimuli and responses were examined. The tasks were performed in Spanish for both groups and performance was indexed with behavioral and electrophysiological measures. We hypothesized that the bilinguals’ daily language practice in L2 reflected overlap conditions similar to the Simon task. Both naming a picture in L2 and the Simon task would involve conflict at the response level. L2 picture naming entails interference between two potential oral responses, to name in L2 vs. L1. Similarly, incongruent stimuli in the Simon task produce interference because the irrelevant dimension overlap with an incorrect response. In contrast, the manual Stroop task involves a different type of conflict between two overlapping stimulus dimensions. We predicted for these reasons a superior performance in Simon tasks over Stroop tasks for bilinguals, while monolinguals were expected to have a similar performance in both tasks. We also expected to see a correlation between the performance on the picture naming task and the Simon task in bilinguals. However, the behavioral results did not confirm these hypotheses. In fact, both groups had similar congruency effects as measured by reaction times and error rates, and there was no correlation between the picture naming and Simon task in bilinguals. Despite this, the electrophysiological data suggested a relationship between the picture naming task and the P300 congruency effect in bilinguals. Our findings provide insights into the neurocognitive bases of language and serve as a research avenue for language behaviors in bilinguals. (shrink)

Lying and deceit are instruments of power, used by social actors in the pursuit of their practices as they seek to maintain social order. All social actors, nurses included, have deceit and dishonesty within their repertoire of practice. Much of this is benign, well intentioned and a function of being sociable and necessary in the pursuit of social order in the healthcare environment. Lying and deceit from a sociological point of view, is a reflection of the different modes of domination (...) that exist within a social space. French philosopher Pierre Bourdieu theorized about the way that symbolic power works within social space. The social structures and the agency of individual actors moving within it are interrelated and interdependent. Bourdieu's ideas will be used to theorize about real clinical experiences where acts of deceit can be identified and a case example will be presented. Nurses are actors in the social space of clinical care, and their world is complex, challenging, and often fraught with the contradictory demands and choices that reflect and influence their behaviours. An exploration of lying and deceit in nursing as an instrument in the modes of domination that persist enables us to challenge some of the assumptions that are made about the motives that cause or tempt nurses to lie as well as to understand the way on which they are sometimes lied to, according to the acts of domination that exist in the field. Lying or acting dishonestly is a powerful act that is intent on retaining stability and social order and could be seen to be a justification of lying and deceit. However, we need to pause and consider, in whose interests are we striving to create social order? Is it in the end about the comfort of patients or for the comfort of professionals? (shrink)

At the end of 2015‘s The Witch, isolated and beaten protagonist, Thomasin, ultimately rejects her puritanical upbringing to become a witch, accepting the invitation of the Devil (in the guise of the family’s goat Black Philip). This essay will discuss Thomasin’s sexual deliverance in terms of her turning away from the authoritarian ‘Law of the Father’ towards female liberation that comes in the form of the Witch. Thomasin transitions from girl to woman, but does not want to do so in (...) the restrictive Puritan fashion where patriarchy and oppression rules. She becomes a woman by embracing her sexuality in the figure of the witch and Black Philip as the figure of lust helping her become free. Western folklore posits the goat as a symbol of fertility, independence, and lust; Black Philip is a figure who represents a connection to wild desires. Therefore, Black Philip becomes not only a physical representation of the devil, but also a symbolic representation of Thomasin’s sexual desire. Drawing on theories of the monstrous-feminine (Creed, Kristeva, Arnold), the symbolism of folklore and Freud’s Electra complex, this work argues that, despite its message of feminine empowerment, The Witch cannot fully reject or escape patriarchal discourse.

The existing ethico-legal regulation of adolescent children's participation in health research in South Africa is currently unclear. The article interrogates the existing framework governing children's consent to research participation, with specific emphasis on discrepancies in consent norms in law and ethical guidelines. Against the backdrop of the constitutional directive that requires that a child's best interests are of paramount importance in every matter concerning the child, the article assesses whether sufficient consideration is given to children's evolving maturity and capacities when (...) consent to their participation in health research is sought. The article provides specific recommendations and proposes a legislative change to consent provisions in the National Health Act 61 of 2003 in order to address the existing lacunae and to align the framework with constitutional imperatives and international fundamental rights considerations.

Children with autism spectrum disorder show marked difficulties in reading comprehension, a complex cognitive skill fundamental to successful daily functioning that is associated with core executive functions. However, the neurophysiological mechanisms underlying reading comprehension deficits in these children remain elusive. Twenty-one right-handed males with high-functioning ASD and 23 age-, IQ-, educational level-, sex- and handedness-matched typically developing individuals underwent a reading comprehension test and the semantic verbal fluency test that tapped core executive functions underlying reading comprehension during concurrent prefrontal functional (...) near-infrared spectroscopy measurement. Participants’ information processing efficiency was also assessed. High-functioning ASD children exhibited general reading comprehension [main effect of group: F = 7.58, p = 0.009], selective verbal fluency deficits [Group × category interaction: F = 4.90, p = 0.032] and slower processing speed. Regarding the hemodynamics of the prefrontal cortex, although ASD individuals showed comparable patterns of PFC brain activation to their healthy counterparts, lower PFC intrahemispheric [main effect of group: F = 11.36, p = 0.002] and interhemispheric [main effect of group: F = 7.79, p = 0.008] functional connectivity were evident during the semantic verbal fluency test. At the whole-group level, poorer reading comprehension performance was associated with poorer performance in the semantic verbal fluency test. Moreover, poorer semantic verbal fluency test performance was associated with slower information processing speed, which is associated with reduced left medial PFC functional connectivity. Abnormal intrahemispheric and interhemispheric prefrontal hypoconnectivity is associated with deficits in executive processes essential for reading comprehension in ASD. Our study has provided important implications for the neuropsychological and neurophysiological mechanisms underlying reading comprehension deficits in ASD. (shrink)

Recent research has provided converging evidence, using multiple tasks, of sensitivity to fairness in the second year of life. In contrast, findings in the first year have been mixed, leaving it unclear whether young infants possess an expectation of fairness. The present research examined the possibility that young infants might expect windfall resources to be divided equally between similar recipients, but might demonstrate this expectation only under very simple conditions. In three violation-of-expectation experiments, 9-month-olds (N = 120) expected an experimenter (...) to divide two cookies equally between two animated puppets (1:1), and they detected a violation when she divided them unfairly instead (2:0). The same positive result was obtained whether the experimenter gave the cookies one by one to the puppets (Experiments 1–2) or first separated them onto placemats and then gave each puppet a placemat (Experiment 3). However, a negative result was obtained when four (as opposed to two) cookies were allocated: Infants looked about equally whether they saw a fair (2:2) or an unfair (3:1) distribution (Experiment 3). A final experiment revealed that 4-month-olds (N = 40) also expected an experimenter to distribute two cookies equally between two animated puppets (Experiment 4). Together, these and various control results support two broad conclusions. First, sensitivity to fairness emerges very early in life, consistent with claims that an abstract expectation of fairness is part of the basic structure of human moral cognition. Second, this expectation can at first be observed only under simple conditions, and speculations are offered as to why this might be the case. (shrink)

Boundary Images investigates the political, material, and visual work that images do to cross and blur the boundaries between the technological and biological and between humans, machines, and nature. Exploring the limits of the visual and beyond what can be seen, Boundary Images posits these boundaries as starting points for the production of new and radically different ways of knowing about the world.

In 1871, the German philosopher Gustav Teichmüller moved from his Basel chair to the much better paid chair in Tartu, and taught there until his untimely death. Besides philosophy, he had studied various disciplines, including the natural sciences. In the preparation of his own philosophy, he explored the history of philosophy for more than twenty years and made pioneering contributions to the history of concepts. Only by the early-1880s did he begin to elaborate his "new philosophy", an original version of (...) personalism, both anti-idealist and anti-materialist. He did this in three major works which built upon each other. Unwritten remained the keystone of his philosophy, the Philosophie des Christentums, in which Teichmüller wanted to show that the philosophical contents of Christianity were encapsulated by his own personalism. One major objective of his philosophy, as I see it, was regaining reality---in particular the reality of the person---after it had been lost in the wake of the failure of modern representationalism. Notwithstanding its coherentist elements, I see Teichmüller's philosophy as a precursor of direct realism. Although he fell into oblivion soon after, his thoughts were received throughout Europe, notably by Friedrich Nietzsche, Aleksey Kozlov and Nicholas Lossky. His extensive literary remains, which are kept in Basel, remain to be explored. (shrink)

Which Books by Teichmüller Did Nietzsche Have Access to? An Attempt at a Reconstruction. The question of which books by Gustav Teichmüller Nietzsche had available has not been satisfactorily clarified to this day. Drawing on sources not considered so far, including the correspondence between Teichmüller and Franz Overbeck and a list that Teichmüller kept about copies of his writings he had sent to colleagues and friends found in his Nachlass, I conclude that Nietzsche only had four books by Teichmüller at (...) his disposal (apart from the opusculum Ueber die Reihenfolge der platonischen Dialoge). Three of these were loans: Aristotelische Forschungen I from the University Library of Basel in the summer semester of 1870, Die Wirkliche und die scheinbare Welt, from Overbeck between late summer 1882 (at the earliest) and November 1885, and the Neue Studien zur Geschichte der Begriffe III also from Overbeck from October 1883 to November 1885. Only the Aristotelischen Forschungen II seem to have been Nietzsche’s personal property (since 1869). Although it is often assumed that Nietzsche also read other books by Teichmüller – e. g., the Studien zur Geschichte der Begriffe, the Neue Studien zur Geschichte der Begriffe II, and the two volumes of the Literarische Fehden im vierten Jahrhundert v. Chr. – they were most likely not available to Nietzsche. (shrink)
