Many authors have recently highlighted the importance of prediction for language comprehension. Pickering & Garrod (P&G) are the first to propose a central role for prediction in language production. This is an intriguing idea, but it is not clear what it means for speakers to predict their own utterances, and how prediction during production can be empirically distinguished from production proper.

A comparison of Merge, a model of comprehension, and WEAVER, a model of production, raises five issues: merging models of comprehension and production necessarily creates feedback; neither model is a comprehensive account of word processing; the models are incomplete in different ways; the models differ in their handling of competition; as opposed to WEAVER, Merge is a model of metalinguistic behavior.

Preparing words in speech production is normally a fast and accurate process. We generate them two or three per second in fluent conversation; and overtly naming a clear picture of an object can easily be initiated within 600 msec after picture onset. The underlying process, however, is exceedingly complex. The theory reviewed in this target article analyzes this process as staged and feedforward. After a first stage of conceptual preparation, word generation proceeds through lexical selection, morphological and phonological encoding, phonetic (...) encoding, and articulation itself. In addition, the speaker exerts some degree of output control, by monitoring of self-produced internal and overt speech. The core of the theory, ranging from lexical selection to the initiation of phonetic encoding, is captured in a computational model, called WEAVER++. Both the theory and the computational model have been developed in interaction with reaction time experiments, particularly in picture naming or related word production paradigms, with the aim of accounting for the real-time processing in normal word production. A comprehensive review of theory, model, and experiments is presented. The model can handle some of the main observations in the domain of speech errors (the major empirical domain for most other theories of lexical access), and the theory opens new ways of approaching the cerebral organization of speech production by way of high-temporal-resolution imaging.

The commentaries provide a multitude of perspectives on the theory of lexical access presented in our target article. We respond, on the one hand, to criticisms that concern the embeddings of our model in the larger theoretical frameworks of human performance and of a speaker's multiword sentence and discourse generation. These embeddings, we argue, are either already there or naturally forgeable. On the other hand, we reply to a host of theory-internal issues concerning the abstract properties of our feedforward spreading (...) activation model, which functions without the usual cascading, feedback, and inhibitory connections. These issues also concern the concrete stratification in terms of lexical concepts, syntactic lemmas, and morphophonology. Our response stresses the parsimony of our modeling in the light of its substantial empirical coverage. We elaborate its usefulness for neuroimaging and aphasiology and suggest further cross-linguistic extensions of the model. (shrink)

How can one conceive of the neuronal implementation of the processing model we proposed in our target article? In his commentary (Pulvermüller 1999, reprinted here in this issue), Pulvermüller makes various proposals concerning the underlying neural mechanisms and their potential localizations in the brain. These proposals demonstrate the compatibility of our processing model and current neuroscience. We add further evidence on details of localization based on a recent meta-analysis of neuroimaging studies of word production (Indefrey & Levelt 2000). We also (...) express some minor disagreements with respect to Pulvermüller's interpretation of the “lemma” notion, and concerning his neural modeling of phonological code retrieval. Branigan & Pickering discuss important aspects of syntactic encoding, which was not the topic of the target article. We discuss their well-taken proposal that multiple syntactic frames for a single verb lemma are represented as independent nodes, which can be shared with other verbs, such as accounting for syntactic priming in speech production. We also discuss how, in principle, the alternative multiple-frame-multiple-lemma account can be tested empirically. The available evidence does not seem to support that account.

Social network structure has been argued to shape the structure of languages, as well as affect the spread of innovations and the formation of conventions in the community. Specifically, theoretical and computational models of language change predict that sparsely connected communities develop more systematic languages, while tightly knit communities can maintain high levels of linguistic complexity and variability. However, the role of social network structure in the cultural evolution of languages has never been tested experimentally. Here, we present results from (...) a behavioral group communication study, in which we examined the formation of new languages created in the lab by micro‐societies that varied in their network structure. We contrasted three types of social networks: fully connected, small‐world, and scale‐free. We examined the artificial languages created by these different networks with respect to their linguistic structure, communicative success, stability, and convergence. Results did not reveal any effect of network structure for any measure, with all languages becoming similarly more systematic, more accurate, more stable, and more shared over time. At the same time, small‐world networks showed the greatest variation in their convergence, stabilization, and emerging structure patterns, indicating that network structure can influence the community's susceptibility to random linguistic changes (i.e., drift).

"Plato's Statesman reconsiders many questions familiar to readers of the Republic: questions in political theory - such as the qualifications for the leadership of a state and the best from of constitution (politeia) - as well as questions of philosophical methodology and epistemology. Instead of the theory of Forms that is the centrepiece of the epistemology of the Republic, the emphasis here is on the dialectical practice of collection and division (diairesis), in whose service the interlocutors also deploy the ancillary (...) methods of myth and of models (paradeigmata). Plato here introduces the doctrine of due measure (to metrion) and a conception of statecraft (politikē) as an architectonic expertise that governs subordinate disciplines such as rhetoric and the military - doctrines later developed by Aristotle. Readers will find a sustained defence of the importance of expertise (technē or epistēmē) in the conduct of affairs of state, a robust (although not unqualified) defence of the rule of law, and an unsparing but nuanced critique of democratic government. The chapters in this volume provide a comprehensive and detailed philosophical engagement with the entirety of Plato's wide-ranging dialogue, with successive chapters devoted to the sections of the dialogue as it unfolds, and an introduction that places the dialogue in the context of Plato's philosophy as a whole. While not a commentary in the traditional sense, the volume engages with Plato's Statesman in its entirety" -- Publisher's description. (shrink)

Recent Anglophone scholarship has successfully shown that Nietzsche's thought makes important contributions to a wide range of contemporary philosophical debates. In so doing, however, scholarship has lost sight of another important feature of Nietzsche's project, namely his desire to challenge the very conception of philosophy that has been used to assess his merits as a philosopher. In other words, contemporary scholarship has overlooked Nietzsche's contributions to metaphilosophy, i.e. debates around the nature, methods, and aims of philosophy. This important new collection (...) of essays brings together an international group of distinguished scholars to explore and discuss these contributions and debates. It will appeal to anyone interested in metaphilosophy, Nietzsche studies, German studies, or intellectual history. (shrink)

Commodity chain analysis (Bair and Ramsay, 2003 Multinational Companies and Global Human Resource Strategies) is used to explore where economic pressure (from consumers) or socio-political pressure (from governments and NGOs) can be applied to reduce worker exploitation. Six paths are illustrated with examples of successful and unsuccessful application of pressure. Three conclusions are reached :Economic pressure on companies and brand owners is more likely to lead to improved workplace conditions than socio-political pressure; Brand owners are more likely to implement improved (...) workplace conditions than retailers; and Retailers who are under extreme consumer price pressure will resist improving workplace conditions.

I was surprised to note the critical tone of the discussion which my friend Leonard B. Meyer recently devoted in these pages to an article on the relation of art and science that I wrote for a popular scientific magazine. For I had believed all the while that in my article I was merely presenting to a general scientific audience a watered-down version of what I thought were Meyer's own views. Evidently I was mistaken in that belief, though (...) I have been unable to fathom just where I went wrong in interpreting Meyer's earlier writings, which, more than any other source, are the provenance of my ideas about the nature of art. Gunther S. Stent, professor of molecular biology at the University of California, Berkeley, is the author of Molecular Biology of Bacterial Viruses, Phage and the Origin of Molecular Biology, Molecular Genetics: An Introductory Narrative, The Coming of the Golden Age: A View of the End of Progress, and many important scientific papers. In Concerning the Sciences, the Arts—AND the Humanities" , Leonard B. Meyer took issue with views expressed by Professor Stent in "Prematurity and Uniqueness in Scientific Discovery," published in Scientific American. (shrink)

This book explores the concept of Life from a range of perspectives. Divided into three parts, it first examines the concept of Life from physics to biology. It then presents insights on the concept from the perspectives of philosophy, theology, and ethics. The book concludes with chapters on the hermeneutics of Life, and pays special attention to the Biosemiotics approach to the concept. The question 'What is Life?' has been deliberated by the greatest minds throughout human history. Life as we (...) know it is not a substance or fundamental property, but a complex process. It is not an easy task to develop an unequivocal approach towards Life combining scientific, semiotic, philosophical, theological, and ethical perspectives. In its combination of these perspectives, and its wide-ranging scope, this book opens up levels and identifies issues which can serve as intersections for meaningful interdisciplinary discussions of Life in its different aspects. The book includes the four plenary lectures and selected, revised and extended papers from workshops of the 14th European Conference on Science and Theology (ECST XIV) held in Tartu, Estonia, April 2012.

Objectives: To examine associations of changing employment conditions, specifically switching to working from home or job loss, with mental health, using data collected during the COVID-19 pandemic.Methods: Data from 2,301 US adults in employment prior to COVID-19 were collected April 3rd−7th, 2020. Participants reported whether their employment remained unchanged, they were WFH when they had not been before, or they had lost their job due to the pandemic. Outcomes were symptoms of depression, anxiety, stress, loneliness, and positive mental health assessed (...) using validated questionnaires. Linear regression quantified associations of employment changes with mental health outcomes, controlling for age, sex, race, BMI, smoking status, screen time, physical activity, marital status, chronic conditions, and current COVID-19 containment strategies being followed.Results: Compared to participants whose employment remained unchanged, those who switched to WFH did not differ in any measures of mental health. Participants who had lost their job reported higher symptoms of depression, anxiety, and stress, and lower PMH. Loneliness did not differ between groups.Conclusion: This study demonstrates that concerns around potential adverse mental health effects, particularly increases in loneliness, should not preclude WFH in the general population, while considering each individual's personal circumstances, and the acute adverse association of job loss with mental health. Tailored and sensitive interventions may be required to prevent deteriorations in mental health associated with job loss during periods of societal stress. (shrink)

In this article, we focus on the concept of leadership ethics and make observations about transformational, transactional and servant leadership. We consider differences in how each definition of leadership outlines what the leader is supposed to achieve, and how the leader treats people in the organization while striving to achieve the organization's goals. We also consider which leadership styles are likely to be more popular in organizations that strive to maximize short run profits. Our paper does not tout or degrade (...) any of these leadership theories. Instead, it points out which theories allow reason to play more than a minimal role in ethical decision-making, as well as those that are most consistent with a firm's desire to achieve efficiency in the short run. We explain our view that the way leadership is practiced in large, bureaucratic organizations suggests that ethics is often absent from the leader's decision-making process. Consequently, we suggest that before we engage in a meaningful dialogue about what kind of leaders we might really want in business, we must consider how much short-run profit we are willing to forego in exchange for more ethical corporate cultures.

In this paper, I provide a thorough discussion and reconstruction of Bernard Bolzano’s theory of grounding and a detailed investigation into the parallels between his concept of grounding and current notions of normal proofs. Grounding (Abfolge) is an objective ground-consequence relation among true propositions that is explanatory in nature. The grounding relation plays a crucial role in Bolzano’s proof-theory, and it is essential for his views on the ideal buildup of scientific theories. Occasionally, similarities have been pointed out between Bolzano’s (...) ideas on grounding and cut-free proofs in Gentzen’s sequent calculus. My thesis is, however, that they bear an even stronger resemblance to the normal natural deduction proofs employed in proof-theoretic semantics in the tradition of Dummett and Prawitz. (shrink)

ObjectiveCochlear explantation for purely elective (e.g. psychological and emotional) reasons is not well studied. Herein, we aim to provide data and expert commentary about elective cochlear implant (CI) removal that may help to guide clinical decision-making and formulate guidelines related to CI explantation.Data sourcesWe address these objectives via three approaches: case report of a patient who desired elective CI removal; review of literature and expert discussion by surgeon, audiologist, bioethicist, CI user and member of Deaf community.Review methodsA systematic review using (...) three scientific online databases was performed. Included articles addressed the benefits and/or complications of cochlear implantation in young children, CI explantation with or without revision surgery and the ethical debate between the medical and Deaf communities on cochlear implantation and explantation.ConclusionsThe medical and audiological perspectives identify a host of risks related to implant removal without reimplantation, including risk from surgery, general anaesthesia, cochlear ossification and poor audiometric outcomes. The member of the deaf community and bioethicist argue that physicians need to guide the principles of beneficence, non-maleficence and patient autonomy. Taken together, patient desires should be seen as paramount, if the patient is otherwise fit for surgery and well informed.Implications for practiceSimilar to the case of device implantation, device explantation should be a multidisciplinary and collaborative decision with the patient and the family’s desires at the centre. While every case is different, we offer a CI explantation discussion to assist in clinical decision-making, patient counselling and education. (shrink)

"As a 'rhetoric of the mean' (mesotes ideal), sensibility provides a positive catalog of emotionalization. This is because ethos as an emotional level is viewed as being able, through gentle emotions, to please, placate and achieve sympathy and virtue (Quintilian). Sensibility in literature creates a bridge between an 'art of the soul' that developed into a major subjective and personal factor in the 18th century and a sense of sociability that aimed to integrate the individual into the community. The goal (...) of this study is to provide, through a structural linking of the ethos of virtue and the 'rhetoric of the mean', a reading of literature of sensibility based on rhetoric and cultural history that can explain both its public success 'with the people' and the reasons for why it failed to meet its own claims."--Publisher's website.

How is it possible to develop an identity that lives from the meaningful relationship to a concrete tradition without falling into fundamentalist self-closure when trying to maintain this relationship? The present study addresses this question by interpreting Alasdair MacIntyre's traditional concept in response to the lack of orientation in contemporary society. The American philosopher Alasdair MacIntyre assumes that modern societies can only convey identity through the traditions they contain. He defines "tradition" as a discussion about the correct interpretation of the (...) traditional content. MacIntyre sees coexistence in plural societies as a permanent encounter of different, traditional identities that struggle to convince each other of the truthfulness of their own worldview. The consequence is not blind conflict, but rather the acquisition of cultural language skills: Real encounters occur when a tradition learns to understand its counterpart from its genuine perspective. In this way, MacIntyre makes communicative competence the guiding factor of its model. In conversation with Karl Barth's theology, the study further develops this model from a Protestant perspective. Barth is received as the 20th century theologian who most consistently thought of Christian identity in particular terms. Even more than for Barth, the self-assurance of Christian tradition is being put to the test today. The study develops a model of Christian orientation in pluralism, which is based on the interplay of cultural competence and trust in the sustainability of one's own religious identity. (shrink)

This book provides a unique, cogent, engaging account of environmental determinism that has long been much needed in the classroom and beyond." -- Andrew Sluyter, Associate Professor, Louisiana State University, USA This book pulls together major critiques of contemporary attempts to explain nature-society relations in an environmentally deterministic way. After defining key terms, it reviews the history of environmental determinism's rise and fall within geography in the early twentieth century. It discusses the key reasons for the doctrine's rejection and presents (...) alternative, non-deterministic frameworks developed within geography for analyzing the roles played by the environment in human affairs. The authors examine the rise in recent decades of neo-deterministic approaches to such issues as the demarcation of regions, the causes of civilizational collapse in prehistory, today's globally uneven patterns of human well-being, and the consequences of human-induced climate change. In each case, the authors draw on the insights and approaches of geography, the academic discipline most conversant with the interactions of society and environment, to challenge the widespread acceptance that such approaches have won. The book will appeal to those working on human-environmental research, international development and global policy initiatives. William B. Meyer is Associate Professor of Geography at Colgate University, USA. He is the author of several previous books, including Human Impact on the Earth, Americans and Their Weather: A History, and The Progressive Environmental Prometheans. His research interests include urban geography, environmental history, and the history of environmental thought. Dylan M.T. Guss works in the technology investment sector. (shrink)
