The human masticatory system is a complex functional unit characterized by a multitude of skeletal components, muscles, soft tissues, and teeth. Muscle activation dynamics cannot be directly measured on live human subjects due to ethical, safety, and accessibility limitations. Therefore, estimation of muscle activations and their resultant forces is a longstanding and active area of research. Reinforcement learning (RL) is an adaptive learning strategy which is inspired by the behavioral psychology and enables an agent to learn the dynamics of an (...) unknown system via policy-driven explorations. The RL framework is a well-formulated closed-loop system where high capacity neural networks are trained with the feedback mechanism of rewards to learn relatively complex actuation patterns. In this work, we are building on a deep RL algorithm, known as the Soft Actor-Critic, to learn the inverse dynamics of a simulated masticatory system, i.e., learn the activation patterns that drive the jaw to its desired location. The outcome of the proposed training procedure is a parametric neural model which acts as the brain of the biomechanical system. We demonstrate the model’s ability to navigate the feasible three-dimensional (3D) envelope of motion with sub-millimeter accuracies. We also introduce a performance analysis platform consisting of a set of quantitative metrics to assess the functionalities of a given simulated masticatory system. This platform assesses the range of motion, metabolic efficiency, the agility of motion, the symmetry of activations, and the accuracy of reaching the desired target positions. We demonstrate how the model learns more metabolically efficient policies by integrating a force regularization term in the RL reward. We also demonstrate the inverse correlation between the metabolic efficiency of the models and their agility and range of motion. The presented masticatory model and the proposed RL training mechanism are valuable tools for the analysis of mastication and other biomechanical systems. We see this framework’s potential in facilitating the functional analyses aspects of surgical treatment planning and predicting the rehabilitation performance in post-operative subjects. (shrink)

Ideomotor actions are behaviours that are unconsciously initiated and express a thought rather than a response to a sensory stimulus. The question examined here is whether ideomotor actions can also express nonconscious knowledge. We investigated this via the use of implicit long-term semantic memory, which is not available to conscious recall. We compared accuracy of answers to yes/no questions using both volitional report and ideomotor response . Results show that when participants believed they knew the answer, responses in the two (...) modalities were similar. But when they believed they were guessing, accuracy was at chance for volitional report , but significantly higher for Ouija response . These results indicate that implicit semantic memory can be expressed through ideomotor actions. They also suggest that this approach can provide an interesting new methodology for studying implicit processes in cognition. (shrink)

The question posed by this text is: can we use Levinasian ethics in the field of literary studies? In order to provide the answer, Levinas?s attitude toward art will need to be analyzed. His work contains numerous scattered remarks about literature and other arts, but the most explicit statement on the relationship between art and ethics can be found in his essay?Reality and Its Shadow?. Since Levinas?s view on art in this essay is predominantly negative, it poses a significant problem (...) for the application of his theory in the field of literary studies. In order to overcome this difficulty, I use Blanchot?s reworking of Levinasian ethics, and open the possibility of a different relation between literature and ethics than the one originally suggested by Levinas.

The aim of this paper is to clarify specific aspects of the impact of the brain-machine interface on our understanding of subjectivity. The brain-machine interface is presented as a phase of cyborgization of humans. Some projects in the field of brain-machine interface are aimed at enabling consensual telepathy - communication without symbolic mediation. Consensual telepathy refers to one of potential ways of transmission of information within singularity. Therefore, consensual telepathy is an important aspect of singularity. Singularity or human-machine symbiosis shows (...) some similarities with child-mother unity. Therefore, the psychodynamic perspective might be considered useful in thinking about human-machine symbiosis. Knowledge from developmental psychodynamic psychology combined with insights by Slavoj Zizek and Jean Baudrillard provides an additional perspective looking at human-machine symbiosis. The paper claims that if consensual telepathy becomes another way of communication, it will have the potential to annihilate subjectivity making it schizophrenic. At the same time, we look at the possibility of an escape from our inner world through the prism of addictions. (shrink)

Combat sports and martial arts are often associated with aggressiveness among the general public, although data on judo and/or martial arts and aggressiveness seem to be unclear. This research aims to compare athletes who have trained judo for a prolonged time and athletes from various team sports, primarily regarding the manifestation of aggression, but also regarding personality traits, emotional intelligence, and self-efficacy. Also, the potential predictive value of personality traits, emotional intelligence, and self-efficacy for aggression within subsamples of judokas and (...) team athletes was tested. The research findings showed that professional judo athletes are characterized by a low degree of aggression, especially low indirect and physical manifestations of aggression. In addition, the personality traits Honesty-Humility and Openness to experience are well expressed, contrary to Emotionality and Extraversion, which are less pronounced. They are also characterized by moderate general self-efficacy. On the other hand, members of team sports produced the opposite results, as they are characterized by increased aggression, pronounced traits of Emotionality and Extraversion, somewhat less pronounced traits of Honesty-Humility, Openness to new experience, and less pronounced general self-efficacy. The percentage of explained variability of aggression is slightly higher in the subsample of team sports and constitutes 49.9% of the variability, while in the subsample of judokas it constitutes 47.8% of the variability of the criteria. Practical implications, limitations, and future research directions were discussed. (shrink)

In this paper, the author aims to show how various implications of poststructuralist theories on the notion of subjectivity can be treated through the so-called “narrative method”. The said narrative method is profiled precisely through the poststructuralist theoretical framework that highlights the elusive character of subjectivity. This insight is used to draw attention to the realm of language, which is a crucial factor in the emergence of any utterance about the structure of our reality. This way of speaking is recognised (...) as essentially narrative, which means that the story must be used as the fundamental unit of language. The narrative method can also be used to intervene in the field that makes its existence possible in the first place. This paper will therefore first analyse texts by Gayatri Spivak, Roberto Calasso and Michel Foucault. These texts will be interpreted from the point of view of the philosophy of stories, which first emerged with the writings of Wilhelm Schapp. It will turn out that these stories bring language closer to its authentic understanding – namely, as a pure multiplicity of contingent stories. To achieve this, we need to apply our narrative method. (shrink)

Ethical issues are pivotal to the practice of psychiatry. Anyone involved in psychiatric practice and mental healthcare has to be aware of the range of ethical issues relevant to their profession. An increased professional commitment to accountability, in parallel with a growing "consumer" movement has paved the way for a creative engagement with the ethical movement. The bestselling 'Psychiatric Ethics' has carved out a niche for itself as the major comprehensive text and core reference in the field, covering a range (...) of complex ethical dilemmas which face clinicians and researchers in their everyday practice. This new edition takes a fresh look at recent trends and developments at the interface between ethics and psychiatric practice. Coming ten years after the third edition, the editors have observed several emerging aspects of psychiatric practice requiring coverage, as a result, 5 new chapters have been added, including cutting edge topics - such as neuroethics. All other chapters have been fully revised and updated. The book will continue to be essential reading for psychiatrists, psychologists, other mental health professionals, and bioethicists, as well as of interest to policy makers, managers and lawyers.

The New Transnational Activism shows how even the most prosaic activities can assume broader political meanings when they provide ordinary people with the experience of crossing transnational space. This means that we cannot be satisfied with defining transnational activists through the ways they think. The defining feature of transnationalism in this book is relational, and not cognitive. This emphasis on activism's relational structure means that even as they make transnational claims, transnational activists draw on the resources, the networks, and the (...) opportunities in which they are embedded, and only then - if at all - on more distant transnational links. But we can no more sharply draw a line between domestic and international politics in studying transnational activism than we could ignore local politics in studying its national equivalent. Understanding the processes that link the local, the national and the international is the major undertaking of the book. (shrink)

Development projects in Sub-Saharan Africa propose to alleviate hunger in rural areas by introducing new agricultural practices and technologies, yet there is limited empirical evidence of how an agricultural intervention can lead farming households to transition to food security. Research on food security pathways considers agricultural interventions that increase farmers’ income to be particularly effective for reducing food insecurity. Consistent with this stance, Malawian agricultural policy aims to address hunger by encouraging smallholder farmers to intensify and commercialize maize production. This (...) paper explores if smallholders’ market and livelihood orientations do indeed lead them to favor an income pathway to food security. Qualitative analysis of 60 smallholder farmer interviews in Malawi found that, upon achieving improvements in production yields and diversity, rather than commercialize, many farmers re-organized their production and consumption to reduce market dependency. Farmers deployed this strategy to increase their food security, explaining that the choice to self-provision food and farming inputs was both an expression of farming identity and a lived understanding of their marginal position in commodity markets. The author finds that, in failing to consider how production relations affect food access, scholarship inadequately theorizes farm-level food security transitions and reproduces discursive framings of hunger. Food sovereignty narratives more accurately captured what mattered for Malawian smallholders’ food security, suggesting that engagement with this concept could improve scientific understandings of food security transitions.

Health care reform that includes universal coverage could lower a major barrier to care for people of color and ethnic minorities—the inability to pay for care. But universal coverage alone, even with comparable fee-for-service payment or appropriately risk-adjusted capitated reimbursement, will not eradicate the racial and ethnic inequities in health care delivery. Restrictive admissions practices, geographic inaccessibility, culture, racial stereotypes, and the failure to employ minority health care professionals will still create barriers to minority health care. In addition to universal (...) financing, health care reform should include new civil rights legislation to address and reduce these noneconomic barriers to minority health care. (shrink)

English summary: Questions of orientation in a globalized world social ethics answered with a Theology of Real. German text. German description: Theologie als Selbstreflexion der Kirche bestimmt deren Identitat dogmatisch. Wenn die Kirche jedoch gefragt ist und Gestalt annimmt, indem sie zum Orientierungswissen der Gesellschaft beitragt, dann antwortet die christliche Traditionsgemeinschaft sozialethisch. Beides wird zusammengehalten durch eine Theologie des Wirklichen. Sie verhindert, dass Verantwortungsethik ins Leere lauft. Dies dokumentieren die Beitrage des vorliegenden Bandes. Die Autoren stehen dabei in der Traditionslinie (...) einer Theologie des Wirklichen, mit der Georg Wunsch vor 80 Jahren in Marburg die deutsche Tradition des Fachgebietes begrundete. Wolfgang Huber, Peter Dabrock und Wolfgang Nethofel zeigen, wie diese Sozialethik sich der Zukunft stellt. Die protestantische Kombination von Freiheit und sozialer Verantwortung fuhrt heute auch die Kirche vor Ort hinein in prinzipiell transdisziplinare und globalisierte Fragestellungen. Sozialethik bewahrt sich dabei im Dialog zwischen verschiedenen Kulturen und Fachdisziplinen. Oekologisch-okonomische Zusammenhange, Bio- und Nanotechnologie eroffnen neue Fragehorizonte und ermoglichen paradigmatische Erfahrungen, die bereits heute in ungewohnten, aber fur die ubrigen theologischen Disziplinen wegweisenden Organisationsformen abgearbeitet werden. Die Gegenwartsdimensionen einer zeitgenossischen Verantwortungsethik eroffnen die Autoren, indem sie fundamental- und materialethische Fragestellungen auch im Kontext der neueren Theologiegeschichte erortern. Und schliesslich zeigen die Beitrage, dass neben der Fach- und Sachkritik auch die geschichtsbewusste Selbstkritik der Sozialethik notwendige Dimensionen einer Verantwortungsethik in protestantischer Tradition sind.

Work requirements are the centerpiece of HHS's Trump Administration strategy to undo the ACA expansion for low income working age adults. This article examines the June 29, 2018 trial court opinion in Stewart v. Azar which held that HHS's approval of Kentucky's Section 1115 work demonstration was “arbitrary and capricious.” The purpose of Medicaid is to provide health coverage and HHS may not ignore the loss of coverage that will result from a work requirement.

In the rationalist tradition in ethics, the emotions are morally suspect. In a corrective swing of the pendulum, burgeoning philosophical interest is “rehabilitating” the emotions in ethical decisionmaking. The emotions and reason should be mutually correcting resources in moral reflection.

Any deviation of speed in a traffic flow from a speed limit represents a potential risk of traffic accidents, so speed management appears as an imperative. However, an inadequately set speed limit often causes drivers’ noncompliance to it in the conditions of real traffic flow. By determining the value of exceeding the speed limit according to vehicle classes, it is possible to recommend a credible speeding value that can be considered credible up to a value above the speed limit. In (...) this paper, deterministic multistep mathematical models of speed deviation from the speed limit as a function of longitudinal gradient for the proposed vehicle classes were developed. A total of 11 measuring sections with different traffic flow types were analyzed. Based on a detailed analysis of speeding, models for the deviation of the 15th, 50th, and 85th percentiles were obtained, with the aim of adjusting the credible deviation to control measures. The results obtained in this study were compared with a survey of traffic flow speeding on two-lane roads conducted in Serbia. (shrink)

We create value for ourselves by making sacrifices. In Sacrifice and Value, Sidney Axinn presents the role of sacrifice in the work of many figures in the history of Philosophy. A novel feature is the attention given to Kant's use of sacrifice, and the way this changes the usual view of the Categorical Imperative, and Kant's concept of value.

This book is a thorough study of the question posed by Kant, For what can a human being rationally hope? It offers a detailed commentary on Kant's seminal work, Religion Within the Limits of Reason Alone, as well as an original development of the logic of three of Kant's basic ideas: ambivalence, ignorance, and hope. Sophisticated analytic techniques, including symbolic logic, are applied to this conceptual matrix. The result is a striking case for the transformation of world society into a (...)

Pain is one of the most frequent presenting symptoms for patients who come to a physician's office. Despite the frequency of this presentation, little consistent, systematic information is provided to medical students or physicians about the treatment of pain. In addition, relatively little information is given about the recognition and prevention of drug abuse and about how to prescribe analgesics rationally to minimize the chances for abuse. This lack of educational preparation for both pain and addiction contributes to significant fear (...) and inability on the part of health professionals to diagnose and treat both conditions. It creates a barrier of fear to prescribe adequate doses of pain medications for patients who present with both acute and chronic pain problems. Inadequate medicating can be caused by the physician's overriding worry about creating addiction in a patient. Morgan has called this problem “opiophobia.”. (shrink)

By examining single-word reading times (in full sentences read for meaning), we show that (1) function words are accessed faster than content words, independent of perceptual characteristics; (2) previous failures to show this involved problems of frequency range and task used; and (3) these differences in lexical access are related to perceptual fluency. We relate these findings to issues in the literature on event-related potentials (ERPs) and neurolinguistics.
