Transcranial direct current stimulation over the contralateral primary motor cortex of the target muscle has been described to enhance corticospinal excitability, as measured with transcranial magnetic stimulation. Recently, tDCS targeting the brain regions functionally connected to the contralateral primary motor cortex was reported to enhance corticospinal excitability more than conventional tDCS. We compared the effects of motor network tDCS, 2 mA conventional tDCS, and sham tDCS on corticospinal excitability in 21 healthy participants in a randomized, single-blind within-subject study design. We (...) applied tDCS for 12 min and measured corticospinal excitability with TMS before tDCS and at 0, 15, 30, 45, and 60 min after tDCS. Statistical analysis showed that neither motor network tDCS nor conventional tDCS significantly increased corticospinal excitability relative to sham stimulation. Furthermore, the results did not provide evidence for superiority of motor network tDCS over conventional tDCS. Motor network tDCS seems equally susceptible to the sources of intersubject and intrasubject variability previously observed in response to conventional tDCS. (shrink)

This article brings critical pressure to bear on two different critical terms: modernism and camp. Arguing that these two historically and theoretically weighted categories have much to tell us when read in relation to each other, this article revisits the short fiction of the canonical modernist Virginia Woolf, and debates the critical significance of the work of a hitherto overlooked late modernist, Charles Henri Ford. Comparing and contrasting the very different writing styles of these important modern cultural producers, this article (...) moves to affirm a fresh and queer object of significant scholarly interest: camp modernism.

Recent literature reported that judgments of semantic coherence are influenced by a positive affective response due to increased fluency of processing. The presented paper investigates whether fluency of processing can be modified by affective responses to the coherent stimuli as well as an automaticity of processes involved in semantic coherence judgments. The studies employed the dyads of triads task in which participants are shown two word triads and asked to solve a semantically coherent one or indicate which of the two (...) is semantically coherent. Across two studies in a dualtask paradigm we show that a) attentional resources moderate insight into semantically coherent word triads, whereas b) judgments of semantic coherence judgments are independent of attentional resources. We discuss implications of our findings for how people might form intuitive judgments of semantic coherence. (shrink)

The future of awake bruxism assessment will incorporate physiological data, possibly electromyography of the temporal muscles. But up to now, temporal muscle contraction patterns in awake bruxism have not been characterized to demonstrate clinical utility. The present study aimed to perform surface EMG evaluations of people assessed for awake bruxism to identify possible different subtypes. A 2-year active search for people with awake bruxism in three regions of the country resulted in a total of 303 participants. Their inclusion was confirmed (...) through non-instrumental approaches for awake bruxism: self-reported questionnaire and clinical exam, performed by three experienced and calibrated dentists. Also, 77 age- and sex-matched healthy controls were recruited. Temporalis surface EMG was performed with a portable device. EMG signals were sent to a computer via Bluetooth 4.0 at a sampling rate of 1,000 Hz. Digital signal processing was performed using the commercial neuroUP software, transformed in RMS and then normalized for peak detection, in a 10 min session. Cluster analysis revealed three distinct subtypes of awake bruxism: phasic, tonic, and intermediate. Individuals with a predominance of EMG peaks/min were classified as the “phasic” subtype. Those with the highest EMG rest power were classified as the “tonic” subtype. There was also an “intermediate” subtype, when both variables remained low. Characterization of awake bruxism physiology is important for future establishment of instrumental assessment protocols and treatment strategies. (shrink)

“Passive fear” denotes a certain type of response to a perceived threat; what is distinctive about the state of passive fear is that its behavioral outlook appears to qualify the emotional experience. I distinguish between two cases of passive fear: one is that of freezing in fear; the other is that of fear-involved tonic immobility. I reconstruct the explanatory strategy that is commonly employed in the field of emotion science, and argue that it leaves certain questions about the nature (...) of passive fear unanswered. I subsequently propose an account of passive fear that builds upon a phenomenological theory of emotions, placing emphasis on the interpretation of current research into human tonic immobility.

This is the first in a series of instalments aiming at a minimal model explanation for conscious experience, taking the phenomenal character of “pure consciousness” or “pure awareness” in meditation as its entry point. It develops the concept of “minimal phenomenal experience” as a candidate for the simplest form of consciousness, substantiating it by extracting six semantic constraints from the existing literature and using sixteen phenomenological case-studies to incrementally flesh out the new working concept. One empirical hypothesis is that the (...) phenomenological prototype of “pure awareness”, to which all such reports refer, really is the content of a predictive model, namely, a Bayesian representation of tonic alertness. On a more abstract conceptual level, it can be described as a model of an unpartitioned epistemic space. (shrink)

Dynamic intra-individual variability (IIV) in cardiac vagal control across multiple situations is believed to contribute to adaptive cognition under stress; however, a dearth of research has empirically tested this notion. To this end, we examined 25 U.S. Army Soldiers (all male, Mean Age= 30.73, SD = 7.71) whose high-frequency heart rate variability (HF-HRV) was measured during a resting baseline and during three conditions of a shooting task (training, low stress, high stress). Response inhibition was measured as the correct rejection of (...) friendly targets during the low and high stress conditions. We tested the association between the standard deviation of HF-HRV across all four task conditions (IIV in vagal control) and changes in response inhibition between low and high stress. Greater differences in vagal control between conditions (larger IIV) were associated with higher tonic vagal control during rest, and stronger stress-related decreases in response inhibition. These results suggest that flexibility in vagal control is supported by tonic vagal control, but this flexibility also uniquely relates to adaptive cognition under stress. Findings are consistent with neurobehavioral and dynamical systems theories of vagal function. (shrink)

Correcting the relationship between tonic and burst firing modes in dopamine neurons may help normalise stimulus-reinforcement gradients and contingent behaviour in attention-deficit/hyperactivity disorder (ADHD) children. But appropriate evaluations of stimuli for developing adaptive plans and controlling impulsivity will not occur without moderating the gain-like functions of serotonin. The “dynamic theory” correctly highlights the need to account for variability in ADHD. The dysmaturation of pre-executive information processing is proposed as an explanation. At the core of the article by Sagvolden and (...) colleagues there is a set of data that throws light on an aspect of the ADHD phenomenon. But one asks if the authors are a measure too brave to generalise so broadly from the unusually steep reinforcement gradients reported for the human condition and an animal model to the syndrome as a whole.

Virtuousness refers to the pursuit of the highest aspirations in the human condition. It is characterized by human impact, moral goodness, and unconditional societal betterment. Several writers have recently argued that corporations, in addition to being concerned with ethics, should also emphasize an ethos of virtuousness in corporate action. Virtuousness emphasizes actions that go beyond the “do no harm” assumption embedded in most ethical codes of conduct. Instead, it emphasizes the highest and best of the human condition. This research empirically (...) examines the buffering and amplifying effects of virtuousness in organizations. The study hypothesizes that virtuousness has a positive effect on organizations because amplifying dynamics make subsequent virtuous action more likely, and buffering dynamics reduce the harmful effects of downsizing. The study reveals that two types of virtuousness – tonic and phasic – are associated with these effects. (shrink)

Toxic speech inflicts individual and group harm, damaging the social fabric upon which we all depend. To understand and combat the harms of toxic speech, philosophers can learn from epidemiology, while epidemiologists can benefit from lessons of philosophy of language. In medicine and public health, research into remedies for toxins pushes in two directions: individual protections (personal actions, avoidances, preventive or reparative tonics) and collective action (specific policies or widespread “inoculations” through which we seek herd immunity). This paper is the (...) beginning of a project of identifying potential inoculations and antidotes to toxic speech. The essay brings a social practice theory of language, with special reliance on language‐games and inferential roles, into conversation with concepts from the study of biologic toxins. Some speech harms are acute while others are chronic and insidious; they have different methods of delivery, come in variable doses, and not everyone is equally susceptible to the power to harm. I argue that of the many kinds of challenges we might issue against toxic speech, challenging its expressive commitments has the greatest potential to stop the damage. The essay explores the different sorts of protections that inoculations and antidotes might offer against discursive toxins and sketches how to imagine these in the practices that govern our speech. The paper does not make policy recommendations, but an epidemiology of discursive toxicity reveals several kinds of “more speech” that might fight against “bad speech.”. (shrink)

Through the personal stories of managers running global business, this book takes an inside look into the dilemmas of managers who are asked to make profits ethically according to the dictates of their company's ethics code. It examines what companies `think" they are doing to help managers in those situations and how those managers are actually affected. Thanks to the boost from the 1991 Sentencing Guidelines which minimizes penalties for companies with ethics codes caught in ethical wrongdoing, more than 85% (...) of US companies and two thirds of all Canadian companies and half of all European companies now have Codes of Ethics. Yet, over and over, we hear of stories of personal dilemmas and conflicts experienced by individual managers navigating those business waters in other cultures. "Eileen Morgan does an excellent job of mapping the course for navigating the previously uncharted global ethical waters. By identifying best practices, she leads the reader on a journey from Surviving, to Understanding to Knowing the ethical issues that frequently confront international business people. This is a must read for anyone who wants to successfully compete in world markets." -Michael J. Litwin, Executive Vice President, Chief Credit Officer, Heller Financial, Inc. "Eileen Morgan has combined the pragmatic concerns of the individual manager with the moral concerns that come from personal-life history, cultural roots, and corporate ethical culture …This book focuses on the constructive task of formulating and using an "ethical map," and is sure to be a tonic to conscientious managers who want to navigate cross-cultural commerce with integrity. It has done a superb job of creating order out of the complexity of cross-cultural moral experience by insisting that the complexity must be honored and appropriated rather than ignored or suppressed." -Dr. Richard Beauchamp, Professor of Ethics, Christopher Newport University "In this groundbreaking book, Eileen Morgan has provided scores of real-life examples and developed a framework for approaching ethical leadership in international business. This is mandatory reading for anyone involved in global management today...This is an important book on an important subject." -Stephen H. Rhinesmith, Ph.D. Author, A Manager's Guide to Globalization "Eileen Morgan provides us with a much needed roadmap for how to walk the path of ethical leadership with practical feet. She reminds us that ethical decision-making is a critical aspect of every day leadership, and that we can all choose to be 'ethical pioneers' in our companies and our communities. Every leader engaged in global business can benefit from the lessons and stories included in this book." -Christi A. Olson, Ph.D. Chair, Telecommunications Management Department, Golden Gate University "Eileen Morgan's thoughtful analysis of 'ethical capital' should be read by anyone who does business in a global environment…Morgan's book presents the issue clearly, comprehensively and compellingly, demonstrating that ethics is an indispensable aspect of individual leadership and organizational credibility. …It provides a clear roadmap for business leaders who need to communicate their commitment to integrity and accountability to their employees, their partners, and their customer, making their 'ethical capital' one of their most valuable assets." -Nell Minnow, Principal, Lens, The Corporate Governance Investors "Eileen Morgan gives excellent insight into ethical practices. She focuses on business but her insights have general application. This book also describes differences in ethical interpretation that can arise between diverse cultures. Ms. Morgan has made an excellent contribution to understanding the benefit of positive ethical practices." -David C. Lincoln, Sponsor, Lincoln Center for Applied Ethics, College of Business, Arizona State University President, Arizona Oxides, LLC · First in-depth look at how managers in global companies actually bridge the gap between their organizations and their daily decisions · Explains the need for internal and external ethical operations¦and how organizations often create confusion rather than clarity with the label of "ethics".
