We assessed how synchronous speech listening and lipreading affects speech recognition in acoustic noise. In simple audiovisual perceptual tasks, inverse effectiveness is often observed, which holds that the weaker the unimodal stimuli, or the poorer their signal-to-noise ratio, the stronger the audiovisual benefit. So far, however, inverse effectiveness has not been demonstrated for complex audiovisual speech stimuli. Here we assess whether this multisensory integration effect can also be observed for the recognizability of spoken words. To that end, we presented audiovisual (...) sentences to 18 native-Dutch normal-hearing participants, who had to identify the spoken words from a finite list. Speech-recognition performance was determined for auditory-only, visual-only (lipreading) and auditory-visual conditions. To modulate acoustic task difficulty, we systematically varied the auditory signal-to-noise ratio. In line with a commonly-observed multisensory enhancement on speech recognition, audiovisual words were more easily recognized than auditory-only words (recognition thresholds of -15 dB and -12 dB, respectively). We here show that the difficulty of recognizing a particular word, either acoustically or visually, determines the occurrence of inverse effectiveness in audiovisual word integration. Thus, words that are better heard or recognized through lipreading, benefit less from bimodal presentation. Audiovisual performance at the lowest acoustic signal-to-noise ratios (45%) fell below the visual recognition rates (60%), reflecting an actual deterioration of lipreading in the presence of excessive acoustic noise. This suggests that the brain may adopt a strategy in which attention has to be divided between listening and lipreading. (shrink)

Background Speech understanding may rely not only on auditory, but also on visual information. Non-invasive functional neuroimaging techniques can expose the neural processes underlying the integration of multisensory processes required for speech understanding in humans. Nevertheless, noise (from fMRI) limits the usefulness in auditory experiments, and electromagnetic artefacts caused by electronic implants worn by subjects can severely distort the scans (EEG, fMRI). Therefore, we assessed audio-visual activation of temporal cortex with a silent, optical neuroimaging technique: functional near-infrared spectroscopy (fNIRS). Methods (...) We studied temporal cortical activation as represented by concentration changes of oxy- and deoxy-hemoglobin in four, easy-to-apply fNIRS optical channels of 33 normal-hearing adult subjects and 5 post-lingually deaf cochlear implant (CI) users in response to supra-threshold unisensory auditory and visual, as well as to congruent auditory-visual speech stimuli. Results Activation effects were not visible from single fNIRS channels. However, by discounting physiological noise through reference channel subtraction, auditory, visual and audiovisual speech stimuli evoked concentration changes for all sensory modalities in both cohorts (p<0.001). Auditory stimulation evoked larger concentration changes than visual stimuli (p<0.001). A saturation effect was observed for the audiovisual condition. Conclusions Physiological, systemic noise can be removed from fNIRS signals by reference channel subtraction. The observed multisensory enhancement of an auditory cortical channel can be plausibly described by a simple addition of the auditory and visual signals with saturation. (shrink)

An important approach to understand how the brain gives rise to consciousness is to probe the depth of unconscious processing, thus to define the key features that cause conscious awareness. Here, we investigate the possibility for subliminal stimuli to shape the context for unconscious processing. Context effects have generally been assumed to require consciousness. In the present experiment, unconscious context processing was investigated by looking at the impact of the context on the response activation elicited by a subliminal prime. We (...) compared the effects of the same subliminal prime on target processing when the prime was embedded in different unconscious contexts. Results showed that the same prime can evoke opposite responses depending on the unconscious context in which it is presented. Taken together, the results of this study show that context effects can be unconscious. (shrink)

‘Stakeholder’ and related notions have been coined to enhance managerial practice in mainstream corporations. Currently, these notions are abundantly present in all kinds of discourses, especially those on ‘socially responsible investing’. But what kind of stakeholder management are these socially responsible investors promoting and what might be reasonable expectations about outcomes? We find that they promote an approach that has shareholder value as motivation and legitimisation and that they nowhere promote sharing of governance with stakeholders other than shareholders. We explain (...) why this might reasonably be expected. Besides mainstream investors and corporations, investing through co-operatively structured corporations differs regarding stakeholder positions with respect to the position of at least one stakeholder group, whether this be consumers, employees or producers. What are the implications thereof and are these investments then superior from a socially responsible perspective on investment? We find that co-operative investors meet their own set of difficulties in implementing stakeholder management. Our questions and findings enable us to formulate some critical remarks on the stakeholder-notion in both discourses and in general. We suggest that its use, if not halted altogether, should at least be restricted and substituted by the use of more specific notions. (shrink)

Henry at Work invites readers to rethink how we work today by exploring an aspect of Henry David Thoreau that has often been overlooked: Thoreau the worker. John Kaag and Jonathan van Belle overturn the popular misconception of Thoreau as a navel-gazing recluse who was scornful of work and other mundanities. In fact, Thoreau worked hard—surveying land, running his family’s pencil-making business, writing, lecturing, and building his cabin at Walden Pond—and thought intensely about work in its many dimensions. And (...) his ideas about work have much to teach us in an age of remote work and automation, when many people are reconsidering what kind of working lives they want to have. -/- Through Thoreau, readers will discover a philosophy of work in the office, factory, lumber mill, and grocery store, and reflect on the rhythms of the workday, the joys and risks of resigning oneself to work, the dubious promises of labor-saving technology, and that most vital and eternal of philosophical questions, “How much do I get paid?” In ten chapters, including “Manual Work,” “Machine Work,” and “Meaningless Work,” this personal, urgent, practical, and compassionate book introduces readers to their new favorite coworker: Henry David Thoreau.

As conventionally understood, corruption relies on a set of universally agreed rules that determine what constitutes the appropriate allocation of organizational resources. This article explores whether rule-based approaches to corruption are applicable where business organizations, such as public private partnerships, and the public fundamentally disagree about what constitutes an appropriate allocation of resources. Drawing on empirical research about PPPs in Vietnam, this article compares how government, business organizations, and the public conceptualize the transfer of public assets into private ownership. It (...) argues that a public interest approach to corruption is needed where PPPs privatize public assets within the law, but against the express wishes of the public. (shrink)

While there is an increasing focus on the use of online networks among autistic users, how autistic adults communicate in social networking sites remains underexplored. The article puts forward an argument for combining systematic observation of digital practices with analysis of evaluative language in order to provide a situated account of ‘autistic sociality’ in social media. Drawing on practice-based theories of social media affordances and discourse analysis research on online self-presentation and affiliation we show how autistic Twitter users rely on (...) association, content persistence and editability in order to signal social engagement through different forms of interaction and alignment. We discuss how the proposed framework can provide a new perspective on communicative practices of autistic social media users and advance development of inclusive digital networking platforms.

Dissociative identity disorder (DID; called multiple personality disorder in DSMIII-R) is a psychiatric condition in which two or more identity states recurrently take control of the person's behavior. A characteristic feature of DID is the occurrence of apparently severe amnestic symptoms. This paper is concerned with experimental research of memory function in DID and focuses on between-identity transfer of newly learned neutral material. Previous studies on this subject are reviewed and a pilot study with four subjects is described. This study (...) is specifically concerned with the question whether self-reported asymmetries in between-identity transfer can be replicated on experimental memory tests. A secondary aim was to examine whether, in the absence of explicit transfer, implicit transfer of information would occur. The results showed that the apparent amnestic asymmetry for explicit information was substantiated in the laboratory, although at least some leakage was present between the apparently amnestic identities. No evidence was found for better performance on implicit than on explicit memory tests in the apparently amnestic identities. In the discussion, parallels between apparent amnesia in DID and state-dependent memory are drawn, and the question of simulated amnesia is addressed. (shrink)

There was a time in the history of philosophy that the phrase “public philosophy” would have been redundant. In this chapter, the authors survey the debate about the professionalization and institutionalization of philosophy between Scott Soames and Robert Frodeman and Adam Briggle. They present an exploration of an example of how professional and non‐professional philosophers may benefit each other. The authors argue that nonprofessional philosophers (whom we might also call “outsider philosophers”) can offer new ways of looking at the canon (...) and broaden the subject matter of philosophy. They present a look forward to the future of interactions between professionalized and outsider philosophers. In an effort to make possible a future where such collaboration is normalized within the broader activity of philosophizing, the authors elucidate both the opportunities and challenges for collaboration.

In mainstream or strong university education, the teacher selects and transmits knowledge and skills that students are to acquire and reproduce. Many researchers of radical embodied cognitive science still adhere to this way of teaching, even though this prescriptive pedagogy deeply contrasts with the theoretical underpinnings of their science. In this paper, we search for alternative ways of teaching that are more aligned with the central non-prescriptive and non-representational tenets of radical embodied cognitive science. To this end, we discuss recent (...) views on education by Tim Ingold and Gert Biesta, which are based on Dewey’s philosophy of pragmatism and Gibsons’ ecological approach. The paper starts by introducing radical embodied cognitive science, particularly as it relates to motor skill learning, one of our prime interests in research and teaching. Next, we provide a synopsis and critique of the still dominant prescriptive and explicating pedagogy of strong education. Following Ingold and Biesta, we search for a weak alternative through a careful consideration of the education of attention and the participating teacher. To illustrate our arguments, we use examples of the first author’s teaching about/of motor skill learning. The paper is concluded by briefly considering the implications of weak education for a radical embodied science of motor skill learning. (shrink)

The problem of justifying legal punishment has been at the heart of legal and social philosophy from the very earliest recorded philosophical texts. However, despite several hundred years of debate, philosophers have not reached agreement about how legal punishment can be morally justified. That is the central issue addressed by the contributors to this volume. All of the essays collected here have been published in the highly respected journal Philosophy & Public Affairs. Taken together, they offer not only significant proposals (...) for improving established theories of punishment and compelling arguments against long-held positions, but also ori-ginal and important answers to the question, "How is punishment to be justified?" Part I of this collection, "Justifications of Punishment," examines how any practice of punishment can be morally justified. Contributors include Jeffrie G. Murphy, Alan H. Goldman, Warren Quinn, C. S. Nino, and Jean Hampton. The papers in Part II, "Problems of Punishment," address more specific issues arising in established theories. The authors are Martha C. Nussbaum, Michael Davis, and A. John Simmons. In the final section, "Capital Punishment," contributors discuss the justifiability of capital punishment, one of the most debated philosophical topics of this century. Essayists include David A. Conway, Jeffrey H. Reiman, Stephen Nathanson, and Ernest van den Haag. (shrink)

This book originates from an international research program that is reassessing when and why modern careers emerged. With fifteen essays this volume brings together some of the most important results of this new field of research. Based upon the innovative use of micro-level historical sources, the contributions by economic and social historians reveal the emergence of identifiable career paths in a wide range of occupational settings in Europe and the Americas over the period 1800 to the end of World War (...) II. They highlight the economic and social forces that shaped the creation of both formal and informal career paths and led to their diffusion throughout the workforces of most developed economies by the early 1950s.

The nature of unconscious information processing is a heavily debated issue in cognitive science, and neuroscience. Traditionally, it has been thought that unconscious cognitive processing is restricted to knowledge that is strongly prepared by conscious processes. In three experiments, we show that the task that is performed consciously can also be applied unconsciously to items outside the current task set. We found that a same–different judgment of two target stimuli was also performed on two subliminally presented prime stimuli. This was (...) true for target and prime stimuli from entirely different categories, as well as for prime and target stimuli at different levels of abstraction. These results reveal that unconscious processing can generalize more widely than previously accepted. (shrink)

The behavior of people in the presence of scarce resources has long been a source of ethical concern and debate. Many of the responses, ranging from outright brutality and cheating on the one hand to altruism, nobility, and sacrifice on the other, were most recently demonstrated in the movie Titanic. It should come as no surprise, then, that rational efforts to allocate the very scarce life-saving resource of organs are sometimes circumvented by these natural human impulses and sheer human creativity. (...) This is especially true when the organs in question are required for continued life and cannot be temporarily or permanently replaced by technology. Thus the focus of this paper will be on the competition for livers. (shrink)

A possible explanation for policy implementation failure is that the views of the policy’s target groups are insufficiently taken into account during policy development. It has been argued that involving these groups in an interactive process of policy development could improve this. We analysed a project in which several target populations participated in workshops aimed to optimise the utilisation of an expensive novel drug (interferon beta) for patients with Multiple Sclerosis. All participants seemed to agree on the appropriateness of establishing (...) a central registry of Multiple Sclerosis patients and developing guidelines. Nevertheless, these policy measures were not implemented. Possible explanations include (1) the subject no longer had high priority when the costs appeared lower than expected, (2) the organisers had paid insufficient attention to the perceived problems of parties involved, and (3) changes within the socio-political context. The workshops in which representatives of the policy’s target populations participated did not provide enough interactivity to prevent policy implementation failure. (shrink)

American football is played in a chaotic visual environment filled with relevant and distracting information. We investigated the hypothesis that collegiate football players show exceptional skill at shielding their response execution from the interfering effects of distraction ( interference control ). The performances of 280 football players from National Collegiate Athletic Association Division I football programs were compared to age-matched controls in a variant of the Eriksen flanker task ( Eriksen and Eriksen, 1974 ). This task quantifies the magnitude of (...) interference produced by visual distraction on split-second response execution. Overall, football athletes and age controls showed similar mean reaction times (RTs) and accuracy rates. However, football athletes were more proficient at shielding their response execution speed from the interfering effects of distraction (i.e., smaller flanker effect costs on RT). Offensive and defensive players showed smaller interference costs compared to controls, but defensive players showed the smallest costs. All defensive positions and one offensive position showed statistically smaller interference effects when compared directly to age controls. These data reveal a clear cognitive advantage among football athletes at executing motor responses in the face of distraction, the existence and magnitude of which vary by position. Individual differences in cognitive control may have important implications for both player selection and development to improve interference control capabilities during play. (shrink)

Many readings of the Parable of the Labourers in the vineyard want to treat the owner as representing God. Knowledge of actual agricultural practices relating to the management of vineyards suggest, on the contrary, that the details of the parable obstruct an easy identification of the owner with God, and that he displays unusual behaviour not only by paying all the labourers the same wage, but by his very intervention in the hiring process. The conclusion reached is that the parable (...) constructs the vineyard owner, typically one of the nouveau riche who lived in cities, not only as a ‘good employer’ but also, contrary to expectation, as a patron who intervened well beyond the strict norms of economic exchange.

Epistemic logic has grown from its philosophical beginnings to find diverse applications in computer science, and as a means of reasoning about the knowledge and belief of agents. This book provides a broad introduction to the subject, along with many exercises and their solutions. The authors begin by presenting the necessary apparatus from mathematics and logic, including Kripke semantics and the well-known modal logics K, T, S4 and S5. Then they turn to applications in the context of distributed systems and (...) artificial intelligence. These include the notions of common knowledge, distributed knowledge, explicit and implicit belief, the interplays between knowledge and time, and knowledge and action, as well as a graded (or numerical) variant of the epistemic operators. The authors also discuss extensively the problem of logical omniscience. They cover Halpern & Moses' theory of honest formulas, and they make a digression into the realm of nonmonotonic reasoning and preferential entailment. They discuss Moore's autoepistemic logic, together with Levesque's related logic of "all I know". Furthermore, they show how one can base default and counterfactual reasoning on epistemic logic. Graduate students in philosophy or in computer science, especially those with an interest in AI, will find this book useful. (shrink)

This article addresses the question of how policymakers could deliberately influence processes of technology development. Using the development of wind turbines in Denmark as an example, the article describes the frames of meaning guiding the actions of those involved in the three subprocesses of policymaking, the generation of new technologies, and the management of the firms that bring new artifacts to the market. The three types of actors share an interest in one notion: the meaning of a technological artifact. This (...) notion, however, plays a different role in the respective frames of meaning of the actors. For policymakers and managers, it is an instrumental notion. For technologists, it provides guidance to their activities. The shared interest affords the possibility of reaching common action with only congruent meanings. Interactive forms of technology assessment can play a central role in bringing about such congruent meanings and thus in influencing the generation of new technologies. (shrink)

Dialogic Teaching is effective in fostering student learning; yet, it is hard to implement. Little research focused on secondary teachers’ learning of DT and on the link between teachers’ understanding and practices, although these two are usually strongly intertwined. Using a wide range of evidence, this case study systematically investigated and compared two secondary teachers’ understanding and practice of DT during their participation in a continuing professional development programme. The CPDP appeared effective to some extent. The History teacher’s understanding of (...) DT, i.e. being a co-learner, appeared highly effective in implementing DT, whereas the Mathematics teacher’s understanding of DT, i.e. creating a democratic learning environment, seemed only effective to some extent. Focusing on both teachers’ understanding and practice when developing DT seemed fruitful in explaining differences in practice. Future research could further explore to what extent understanding DT as being a co-learner facilitates professional development. (shrink)

The first quodlibetal question by William of Alnwick is a reply to John Duns Scotus' Quaestio de Formalitatibus, where the latter clarified his understanding of the formal distinction: ‘formal non-identity’ of the personal properties in God (and of the divine attributes) does not preclude a formal distinction if the latter is conceived as a distinction weakened by the modifier ‘formal’. Whereas Scotus' Quaestio has been subjected to a detailed analysis by Stephen Dumont, “Duns Scotus’ Parisian Question”, there is as (...) yet no such analysis of Alnwick's response. In the present paper his position is explained in detail. Alnwick rejects Scotus' view of ‘formal’ as a weakening modifier; he argues that the formal distinction necessarily is unqualified and may still import too much of unwanted realism in the matter at hand. Both Scotus and Alnwick acknowledge that the formal non-identity reflects the nature of things without falling back to a real distinction. But for Alnwick the right kind of distinction is a qualified distinction that is not a formal distinction. (shrink)
