Event-related desynchronization, as a proxy for mirror neuron activity, has been used as a neurophysiological marker for motor execution after mirror visual feedback. Using EEG, this study investigated ERD upon the immediate effects of single-session MVF in unimanual arm movements compared with the ERD effects occurring without a mirror, in two groups: stroke patients with left hemiplegia and their healthy counterparts. During EEG recordings, each group performed one session of mirror therapy training in three task conditions: with a mirror, with (...) no mirror, and with a covered mirror. An asymmetry index was calculated from the subtraction of the event-related spectrum perturbations between the C3 and C4 electrodes located over the sensorimotor cortices contralateral and ipsilateral to the moved arm. Results of the effect of task versus group in contralateral and ipsilateral motor areas showed that there was a significant effect of task condition at the contralateral motor area in the high beta band at C3. High beta ERD showed that the suppression was greater over the contralateral hemisphere than it was over the ipsilateral hemisphere in both study groups. The magnitude of low beta ERD in patients with stroke was more suppressed in contralesional C3 under the no mirror compared to that of the covered mirror and similarly more suppressed in ipsilesional C4 ERD under the no mirror compared to that of the mirror condition. The correlation analysis revealed that the magnitude of ERSP power correlated significantly with arm severity in the low and high beta bands in patients with stroke, and a higher asymmetry index in the low beta band was associated with higher arm functioning under the no-mirror condition. There was a shift in sensorimotor ERD toward the contralateral hemisphere as induced by MVF accompanying unimanual movement in both stroke patients and healthy controls. The use of ERD in the low beta band as a neurophysiological marker to indicate the relationships between the amount of MVF-induced ERD attenuation and motor severity, and the outcome indicator for improving stroke patients’ neuroplasticity in clinical trials using MVF are warranted to be explored in the future.

The proposition that feedback is never necessary in speech recognition is examined for utterances consisting of sequences of words. In running speech the features near word boundaries are often modified according to language-dependent rules. Application of these rules during word recognition requires top-down processing. Because isolated words are not usually modified by rules, their recognition could be achieved by bottom-up processing only.

A corrected and extensively annotated version of the sole meeting between two of the most important figures in twentieth-century intellectual life.

The potential benefits of priming intermittent theta burst stimulation with continuous theta burst stimulation have not been examined in regard to sensorimotor oscillatory activities recorded in electroencephalography. The objective of this study was to investigate the modulatory effect of priming iTBS delivered to the motor cortex on movement-related and mirror visual feedback -induced sensorimotor event-related desynchronization, compared with iTBS alone, on healthy adults. Twenty participants were randomly allocated into Group 1: priming iTBS—cTBS followed by iTBS, and Group 2: non-priming iTBS—sham (...) cTBS followed by iTBS. The stimulation was delivered to the right primary motor cortex daily for 4 consecutive days. EEG was measured before and after 4 sessions of stimulation. Movement-related ERD was evaluated during left-index finger tapping and MVF-induced sensorimotor ERD was evaluated by comparing the difference between right-index finger tapping with and without MVF. After stimulation, both protocols increased movement-related ERD and MVF-induced sensorimotor ERD in high mu and low beta bands, indicated by significant time effects. A significant interaction effect favoring Group 1 in enhancing movement-related ERD was observed in the high mu band [F = 4.47, p = 0.049], compared with Group 2. Our experiment suggests that among healthy adults priming iTBS with cTBS delivered to the motor cortex yields similar effects with iTBS alone on enhancing ERD induced by MVF-based observation, while movement-related ERD was more enhanced in the priming iTBS condition, specifically in the high mu band.

This article draws attention to the origins, forms, and implications of “toxic discourse” as a genre central to the understanding of the public sphere in business in society.RachelCarson'sSilentSpringis used as a pivotal cultural document establishing “toxic discourse” as an ongoing form of moral narrative rooted in the rationality of counterpublics. Toxic discourse is framed within a center/periphery model in which toxic discourse gains salience in periods of economic dislocation and uncertainty. In these periods, toxic discourse draws together those on the (...) periphery or counterpublics who otherwise would not unite in their opposition to the center. The article critically examines how stakeholder theory, despite making sense of the public sphere for agents of organizations, glosses counterpublics and relegates toxic discourse, as evident in the “Occupy Movement,” to the ephemeral role of temporary, disruptive protest groups with very little of substance to communicate.

This essay describes conversation as an ensemble accomplishment that can be illuminated by critics working with specific texts within a rhetorical framework. We first establish dialogue as the key concept for any criticism of conversation, specifying the rhetorical dimensions of interpersonal dialogue. Second, we show how template thinking is particularly dangerous for conversational critics and suggest a research (anti)method, based on a coauthorship, that provides a thoroughgoing dialogical access to texts. Finally, we exemplify dialogic criticism of a conversational text by (...) analyzing the famous 1957 dialogue of philosopher Martin Buber and psychologist Carl Rogers. (shrink)

Upon doing something generous for someone with whom you are close, some kind of reciprocity may be appropriate. But it often seems wrong to actually request reciprocity. This chapter explores the wrongness in making these requests, and why they can nevertheless appear appropriate. After considering several explanations for the wrongness at issue (involving, e.g. distinguishing oughts from obligation, the suberogatory, imperfect duties, and gift-giving norms), a novel proposal is advanced. The requests are disrespectful; they express that their agent insufficiently trusts (...) the hearer to recognize their own reasons to reciprocate, and the close relationship between them morally requires this kind of trust. This proposal is articulated and situated in the recent discussion of the normativity of requests. The chapter concludes by explaining how these requests may appear appropriate. Agents in these relationships often have standing to make requests, though the standing is lacking in these particular cases. (shrink)

ABSTRACTThis work explores financial edgework by professional speculative traders as an explanation for the persistence of rogue trading in financial markets. The article joins in the scholarly application of “edgework,” the social psychological study of voluntary risk, to speculative trading. The discussion focuses on the origins and persistence of that subset of behavior wherein the trader knowingly creates the condition in which he or she endangers the brokerage house that employs them and even, at times, threatens the public's perception of (...) the integrity of the securities industry. Going over the edge between risk taking and unauthorized rogue trading is explained by looking at five inducements to escalate risk taking provided in the securities industry. This examination of financial edgework demonstrates how and, to a lesser degree, why rogue trading is a result of the security industry's pursuit of and desire to capitalize upon yet not publicize an occupational culture stressing a “risk‐and‐win” ethos.

This paper provides an analysis of the dynamics of secrecy and the secrets business. Secrets are defined as bits of information that, for one reason or another, are kept hidden or controlled so as to elude attention, observation or comprehension. Three conceptual lenses — the micro-analytic focusing on self-deception, the social-psychological focusing on self-disclosure, and the macro-analytic focusing on public secrets — are probed. Secrecy at each of the three levels is revealed to be a janusfaced issue providing undeniable benefits (...) to Homo sapiens in their efforts to adapt to a changing world yet also creates undeniable problems. While secrecy provides the occasion for the demonstration of loyalty and intimacy, it also generates the conditions for exclusion and betrayal. The contemporary impulse to create public forums in which all is revealed, in which sunlight prevails, is too simple a panacea to those who use the topic of secrecy as an occasion to correct social, political and economic problems.

This article investigates the social accounts employed by 11 highly paid professionals and managers for neutralizing the moral stigma of losing their job due to resume fraud. This ethnographic study, based on 66 hours of interviews, explores the retrospective sense making used by resume fraudsters to justify, personally pardon and excuse behaviour seen as morally problematic by others. In this study the resume fraudsters sampled were selected because they all found high-paying jobs after their public humiliation, and each one morally (...) disengages. They put their transgressions behind them, not by seeing the light of day or asking for forgiveness, but by pointing to the ubiquity of information distortion in their companies, the victimless nature of their so-called transgression, and, most interesting, a portrayal of themselves and their act of resume fraud as the very type of risk taking required to instil capitalism with a passion and a will to succeed. The article closes with a discussion of how moral disengagement enlarges the zone of indifference in populations and reinforces cultures in which the pursuit of amorality thrives. (shrink)

ABSTRACTThis article takes an interdisciplinary lens to the treatment of regulatory capture . RC ensues when government bureaucrats, regulators, and public sector agencies receive adverse publicity for ceasing to serve the wider collective public interest. The work is divided into four sections. The first takes the point of view of each of the participants in the capture situation and provides an overview of the three variations on the RC story. Each subsequent section focuses on a version of the story. RC (...) 1, the libertarian free market version celebrates capture as inevitable and desirable. RC 2, the regulators' communitarian take on capture places it in the context of a cycle story with regulators dutifully doing the public's shifting will. In the RC 3 version, the public finds it difficult to piece together a coherent version of the morally charged narrative. The article concludes with a discussion of the relevance of each of these three versions of RC in order to understand dominant–submissive relationships between business and government. (shrink)

On one hand, Chinese consumers are well known for conspicuous consumption and the adoption of luxury products and named brands. On the other hand, they also have a bad reputation for buying counterfeit products. Their simultaneous preferences for two contrasting types of product present a paradox that has not been addressed in the literature. This study attempts to present an explanation of this paradox by examining the effects of traditional Chinese cultural values and consumer values on consumers’ deontological judgment of (...) pirated CDs and the amount of social benefits they perceive they gain from them. We interviewed 300 Hong Kong Chinese consumers, and found that face consciousness increased materialism and risk aversion, thereby producing a favorable deontological judgment of pirated CDs. Face consciousness also has a direct effect on the amount of social benefits perceived in pirated CDs. Both favorable deontological judgment and perceived social benefits contributed to a strong intention to buy pirated CDs. The results are discussed in a cultural perspective. (shrink)

Several influential philosophers and scientists have advanced a framework, often called Neo-Cartesianism (NC), according to which animal suffering is merely apparent. Drawing upon contemporary neuroscience and philosophy of mind, Neo-Cartesians challenge the mainstream position we shall call Evolutionary Continuity (EC), the view that humans are on a nonhierarchical continuum with other species and are thus not likely to be unique in consciously experiencing negative pain affect. We argue that some Neo-Cartesians have misconstrued the underlying science or tendentiously appropriated controversial views (...) in the philosophy of mind. We discuss recent evidence that undermines the simple neuroanatomical structure-function correlation thesis that undergirds many Neo-Cartesian arguments, has an important bearing on the recent controversy over pain in fish, and places the underlying epistemology framing the debate between NC and EC in a new light that strengthens the EC position.

Several well-known theodicies, whatever their merits, seem to make little sense of animal suffering. Here we argue that the problem of animal suffering has more layers than has generally been acknowledged in the literature and thus poses an even greater challenge to traditional Judeo-Christian Theism than is normally thought. However, the Neo-Cartesian (NC) defence would succeed in defanging this Expanded Problem of Animal Suffering. Several contemporary philosophers have suggested that recent evidence either supports the NC view or at least should (...) decrease our incredulity with respect to it. We discuss new evidence that undermines the NC position and thus reassert the gravity of the Expanded Problem. (shrink)

The inventor of the concepts of emics and etics, linguist Kenneth Pike, uses this volume as a forum to explain their development and their usage today. He is joined in the debate by renowned anthropologist Marvin Harris. Eight other scholars add to the scholarly discourse and demonstrate applications of the concepts in a variety of disciplines. Referring to insider versus outsider, subjective versus objective views of the world, these concepts are vital for researchers dealing with cultures other than their (...) own. (shrink)

Recent studies have provided evidence of associations between neurochemistry and reading (dis)ability (Pugh et al., 2014). Based on a long history of studies indicating that fluent reading entails the automatic convergence of the written and spoken forms of language and our recently proposed Neural Noise Hypothesis (Hancock et al., 2017), we hypothesized that individual differences in cross-modal integration would mediate, at least partially, the relationship between neurochemical concentrations and reading. Cross-modal integration was measured in 231 children using a two-alternative forced (...) choice cross-modal matching task with three language conditions (letters, words, and pseudowords) and two levels of difficulty within each language condition. Neurometabolite concentrations of Choline (Cho), Glutamate (Glu), gamma-Aminobutyric (GABA), and N- acetyl-aspartate (NAA) were then measured in a subset of this sample (n = 70) with Magnetic Resonance Spectroscopy (MRS). A structural equation mediation model revealed that the effect of cross-modal word matching mediated the relationship between increased Glu (which has been proposed to be an index of neural noise) and poorer reading ability. In addition, the effect of cross-modal word matching fully mediated a relationship between increased Cho and poorer reading ability. Multilevel mixed effects models confirmed that lower Cho predicted faster cross-modal matching reaction time, specifically in the hard word condition. These Cho... (shrink)

Après avoir erré quelques années, étudiant férocement studieux mais aussi très anarchiste, après avoir déambulé le long des docks du port de Glasgow, alors du dernier stade de la révolution industrielle, entouré d'une drôle de musique où les accents de Rimbaud («Je me crois en enfer») et de Hölderlin («Ce que tu veux, c'est un monde») se mêlaient aux phrasés grinçants de L'Opéra de quat'sous de Bertolt Brecht, je me posais la question : que faire? Que faire de fondamental? D'abord (...) pour donner un fondement et un mouvement à une existence individuelle, mais aussi pour tenter de changer le cours des choses, sur les plans culturel, civilisationnel et sociopolitique. Pendant le XIXe et le XXe siècle on a cru, malgré tout, que l'Histoire était synonyme de Progrès. Qu'elle menait quelque part : à un grand Etat, au communisme universel, à un Supermarché du bonheur. Personne n'a plus confiance dans l'Histoire. D'où un grand vide existentiel et culturel. Sans utopisme, sans réenchantement facile, Kenneth White entreprend une navigation hauturière dans un espace de vie et de pensée, qui a toujours existé au large de l'Histoire. Les escales de ce voyage sont au nombre de cinq : une analyse socio-politique de la fin de la modernité ; une investigation qui remonte aux origines de la culture ; l'examen de diverses tentatives de refondation sociale à travers le monde ; la question, posée encore trop timidement par l'écologie, de l'habitation de la Terre ; et enfin, une critique de la situation contemporaine de l'art.

BackgroundAn increasing number of studies utilize intracranial electrophysiology in human subjects to advance basic neuroscience knowledge. However, the use of neurosurgical patients as human research subjects raises important ethical considerations, particularly regarding informed consent and undue influence, as well as subjects’ motivations for participation. Yet a thorough empirical examination of these issues in a participant population has been lacking. The present study therefore aimed to empirically investigate ethical concerns regarding informed consent and voluntariness in Parkinson’s disease patients undergoing deep brain (...) stimulator (DBS) placement who participated in an intraoperative neuroscience study.MethodsTwo semi-structured 30-minute interviews were conducted preoperatively and postoperatively via telephone. Interviews assessed participants’ motivations for participation in the parent intraoperative study, recall of information presented during the informed consent process, and participants’ postoperative reflections on the research study.ResultsTwenty-two participants (mean age = 60.9) completed preoperative interviews at a mean of 7.8 days following informed consent and a mean of 5.2 days prior to DBS surgery. Twenty participants completed postoperative interviews at a mean of 5 weeks following surgery. All participants cited altruism or advancing medical science as “very important” or “important” in their decision to participate in the study. Only 22.7% (n = 5) correctly recalled one of the two risks of the study. Correct recall of other aspects of the informed consent was poor (36.4% for study purpose; 50.0% for study protocol; 36.4% for study benefits). All correctly understood that the study would not confer a direct therapeutic benefit to them.ConclusionEven though research coordinators were properly trained and the informed consent was administered according to protocol, participants demonstrated poor retention of study information. While intraoperative studies that aim to advance neuroscience knowledge represent a unique opportunity to gain fundamental scientific knowledge, improved standards for the informed consent process can help facilitate their ethical implementation.
