Access to communication is critical for individuals with late-stage amyotrophic lateral sclerosis and minimal volitional movement, but they sometimes present with concomitant visual or ocular motility impairments that affect their performance with eye tracking or visual brain-computer interface systems. In this study, we explored the use of modified eye tracking and steady state visual evoked potential BCI, in combination with the Shuffle Speller typing interface, for this population. Two participants with late-stage ALS, visual impairments, and minimal volitional movement completed a (...) single-case experimental research design comparing copy-spelling performance with three different typing systems: commercially available eye tracking communication software, Shuffle Speller with modified eye tracking, and Shuffle Speller with SSVEP BCI. Participant 1 was unable to type any correct characters with the commercial system, but achieved accuracies of up to 50% with Shuffle Speller eye tracking and 89% with Shuffle Speller BCI. Participant 2 also had higher maximum accuracies with Shuffle Speller, typing with up to 63% accuracy with eye tracking and 100% accuracy with BCI. However, participants’ typing accuracy for both Shuffle Speller conditions was highly variable, particularly in the BCI condition. Both the Shuffle Speller interface and SSVEP BCI input show promise for improving typing performance for people with late-stage ALS. Further development of innovative BCI systems for this population is needed. (shrink)

Augmentative and alternative communication brain-computer interface systems are intended to offer communication access to people with severe speech and physical impairment without requiring volitional movement. As the field moves toward clinical implementation of AAC-BCI systems, research involving participants with SSPI is essential. Research has demonstrated variability in AAC-BCI system performance across users, and mixed results for comparisons of performance for users with and without disabilities. The aims of this systematic review were to describe study, system, and participant characteristics reported in (...) BCI research, summarize the communication task performance of participants with disabilities using AAC-BCI systems, and explore any differences in performance for participants with and without disabilities. Electronic databases were searched in May, 2018, and March, 2021, identifying 6065 records, of which 73 met inclusion criteria. Non-experimental study designs were common and sample sizes were typically small, with approximately half of studies involving five or fewer participants with disabilities. There was considerable variability in participant characteristics, and in how those characteristics were reported. Over 60% of studies reported an average selection accuracy ≤70% for participants with disabilities in at least one tested condition. However, some studies excluded participants who did not reach a specific system performance criterion, and others did not state whether any participants were excluded based on performance. Twenty-nine studies included participants both with and without disabilities, but few reported statistical analyses comparing performance between the two groups. Results suggest that AAC-BCI systems show promise for supporting communication for people with SSPI, but they remain ineffective for some individuals. The lack of standards in reporting outcome measures makes it difficult to synthesize data across studies. Further research is needed to demonstrate efficacy of AAC-BCI systems for people who experience SSPI of varying etiologies and severity levels, and these individuals should be included in system design and testing. Consensus in terminology and consistent participant, protocol, and performance description will facilitate the exploration of user and system characteristics that positively or negatively affect AAC-BCI use, and support innovations that will make this technology more useful to a broader group of people.Clinical trial registrationhttps://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42018095345, PROSPERO: CRD42018095345.

Cognitive functions like perception, memory, language, or consciousness are based on highly parallel and distributed information processing by the brain. One of the major unresolved questions is how information can be integrated and how coherent representational states can be established in the distributed neuronal systems subserving these functions. It has been suggested that this so-called ''binding problem'' may be solved in the temporal domain. The hypothesis is that synchronization of neuronal discharges can serve for the integration of distributed neurons into (...) cell assemblies and that this process may underlie the selection of perceptually and behaviorally relevant information. As we intend to show here, this temporal binding hypothesis has implications for the search of the neural correlate of consciousness. We review experimental results, mainly obtained in the visual system, which support the notion of temporal binding. In particular, we discuss recent experiments on the neural mechanisms of binocular rivalry which suggest that appropriate synchronization among cortical neurons may be one of the necessary conditions for the buildup of perceptual states and awareness of sensory stimuli.

In a recent review essay of a two volume anthology on left-libertarianism (edited by two of us), Barbara Fried has insightfully laid out most of the core issues that confront left-libertarianism. We are each left-libertarians, and we would like to take this opportunity to address some of the general issues that she raises. We shall focus, as Fried does much of the time, on the question of whether left-libertarianism is a well-defined and distinct alternative to existing forms of liberal egalitarianism. (...) More specifically, we shall address the following fundamental issues raised by Fried (and others): (1) Does the notion self-ownership have any determinate content? (2) What is the relation between self-ownership and world ownership? (3) How is left-libertarianism different from other forms of liberal egalitarianism (e.g., those of Rawls and Dworkin)? (shrink)

while kant's transcendental philosophy as expounded in the Critique of Pure Reason and the Prolegomena has been extraordinarily influential over the past two centuries, its transcendental methodology has continued to puzzle commentators. Recently, Colin Marshall, in an article entitled "Does Kant Demand Explanations for All Synthetic A Priori Claims?," has brought one of the central problems for any interpretation of Kant's methodology to the fore again.1 In his paper, Marshall discusses what he calls "the Regress Puzzle": Several commentators have noted (...) that there is a puzzle about how the positive part of Kant's project could work. The puzzle, which I will call the "Regress Puzzle," arises when we ask: If Kant... (shrink)

In recent years, the opioid crisis in the United States has sparked significant discussion on doctor–patient interactions concerning chronic pain treatments, but little to no attention has been given to investigating the vocal aspects of patient talk. This exploratory sociolinguistic study intends to fill this knowledge gap by employing prosodic discourse analysis to examine context-specific linguistic features used by the interlocutors of two distinct medical interactions. We found that patients employed both low pitch and creak as linguistic resources when describing (...) chronic pain, narrating symptoms and requesting opioids. The situational use of both features informs us about the linguistic ways in which patients frame fraught issues like chronic pain in light of the current opioid crisis. This study expands the breadth of phonetic analysis within the domain of discourse analysis, serving to illuminate discussions surrounding the illocutionary role of the lower vocal tract in expressing emotions.

In this essay I attempt to unpack Andy Kaufman in his many manifestations, ultimately arguing that traditional notions of comedy cannot help us get at the root of what is going on here. Through a discussion and criticism of the theories of comedy presented by Christopher Fry, Susanne Langer, Walter Kerr, and Maurice Charney, I suggest how Andy's comedy employs a rejection of the modernist conceits of a fixed identity, a denotative language, a progressive history, and a separation of temporality (...) from Being. Ultimately focusing on the way in which Freud's theory of comedy gets deconstructed when we read it through the lens of Andy’s work, I take apart specific jokes and comedic “moments” in Andy's work and show how the Freudian framework cannot support such an aesthetic. What is, in fact, most challenging in Andy's work as a comedian is not merely the way in which his own identity is up for grabs but the way in which he forces the audience to have its identity as an audience called into question, the way in which a Baudrillardean simulacrum stands in for a missing punchline while we, his fans, wait for something that is never coming. And yet we, his fans, laugh. Sometimes uncomfortably, but always more authentically. (shrink)

Chaotic dynamics has been hailed as the third great scientific revolution in physics this century, comparable to relativity and quantum mechanics. In this book, Peter Smith takes a cool, critical look at such claims. He cuts through the hype and rhetoric by explaining some of the basic mathematical ideas in a clear and accessible way, and by carefully discussing the methodological issues which arise. In particular, he explores the new kinds of explanation of empirical phenomena which modern dynamics can (...) deliver. Explaining Chaos will be compulsory reading for philosophers of science and for anyone who has wondered about the conceptual foundations of chaos theory. (shrink)

Martin Heidegger’s sustained reflection on Greek thought has been increasingly recognized as a decisive feature of his own philosophical development. At the same time, this important philosophical meeting has generated considerable controversy and disagreement concerning the radical originality of Heidegger’s view of the Greeks and their place in his groundbreaking thinking. In Heidegger and the Greeks, an international group of distinguished philosophers sheds light on the issues raised by Heidegger’s encounter and engagement with the Greeks. The careful and nuanced essays (...) brought together here shed light on how core philosophical concepts such as phenomenology, existentialism, hermeneutics, and ethics are understood today. For readers at all levels, this volume is an invitation to continue the important dialogue with Greek thinking that was started and stimulated by Heidegger. Contributors are Claudia Baracchi, Walter A. Brogan, Günter Figal, Gregory Fried, Francisco J. Gonzalez, Drew A. Hyland, John Panteleimon Manoussakis, William J. Richardson, John Sallis, Dennis J. Schmidt, and Peter Warnek. (shrink)

The purpose of this article is to report what can be learned about nurses’ ethical conflicts by the systematic analysis of methodologically similar studies. Five studies were identified and analysed for: (1) the character of ethical conflicts experienced; (2) similarities and differences in how the conflicts were experienced and how they were resolved; and (3) ethical conflict themes underlying four specialty areas of nursing practice (diabetes education, paediatric nurse practitioner, rehabilitation and nephrology). The predominant character of the ethical conflicts was (...) disagreement with the quality of medical care given to patients. A significant number of ethical conflicts were experienced as ‘moral distress’, the resolution of which was variable, depending on the specialty area of practice. Ethical conflict themes underlying the specialty areas included: differences in the definition of adequacy of care among professionals, the institution and society; differences in the philosophical orientations of nurses, physicians and other health professionals involved in patient care; a lack of respect for the knowledge and expertise of nurses in specialty practice; and difficulty in carrying out the nurse’s advocacy role for patients.

Advances in molecular biological research in the latter half of the twentieth century have made the story of the gene vastly complicated: the more we learn about genes, the less sure we are of what a gene really is. Knowledge about the structure and functioning of genes abounds, but the gene has also become curiously intangible. This collection of essays renews the question: what are genes? Philosophers, historians and working scientists re-evaluate the question in this volume, treating the gene as (...) a focal point of interdisciplinary and international research. It will be of interest to professionals and students in the philosophy and history of science, genetics and molecular biology. (shrink)

Kant's Critique of Teleological Judgment is read as a reflection on philosophical methodological problems that arose through the constitution of an independent science of life - biology. This work presents an example of the interconnections between philosophy and the history of science.

This volume brings together eleven essays by the distinguished philosopher of science, Peter Achinstein. The unifying theme is the nature of the philosophical problems surrounding the postulation of unobservable entities such as light waves, molecules, and electrons. How, if at all, is it possible to confirm scientific hypotheses about "unobservables"? Achinstein examines this question as it arose in actual scientific practice in three nineteenth-century episodes: the debate between particle and wave theorists of light, Maxwell's kinetic theory of gases, and (...) J.J. Thomson's discovery of the electron. The book contains three parts, each devoted to one of these topics, beginning with an essay presenting the historical background of the episode and an introduction to the philosophical issues. There is an illuminating evaluation of various scientific methodologies, including hypothetico-deductivism, inductivism, and the method of independent warrant which combines features of the first two. Achinstein assesses the philosophical validity of both nineteenth-century and modern answers to questions about unobservables, and presents and defends his own solutions. (shrink)

Peter Anstey rejects the widespread view that all knowledge for Locke is propositional. He argues, instead, that Locke accepts a form of non-propositional knowledge. The perception of the agreement and disagreement of ideas, according to Anstey's interpretation, is akin to what Bertrand Russell called “knowledge by acquaintance.” He presents a careful, four-step analysis of Locke’s view of the acquisition of knowledge, which is designed to show how the mind proceeds from perceiving to affirming, then to assenting, and finally to (...) verbalizing propositions. This comprehensive account takes into account a variety of remarks Locke makes about perception, knowledge and true or false propositions, and Anstey claims that overall this interpretation is a better fit than the orthodox view that Locke held all knowledge to be propositional.

The development of nursing ethics as a field of inquiry has largely relied on theories of medical ethics that use autonomy, beneficence, and/or justice as foundational ethical principles. Such theories espouse a masculine approach to moral decision-making and ethical analysis. This paper challenges the presumption of medical ethics and its associated system of moral justification as an appropriate model for nursing ethics. It argues that the value foundations of nursing ethics are located within the existential phenomenon of human caring within (...) the nurse/patient relationship instead of in models of patient good or rights-based notions of autonomy as articulated in prominent theories of medical ethics. Models of caring are analyzed and a moral-point-of-view (MPV) theory with caring as a fundamental value is proposed for the development of a theory of nursing ethics. This type of theory is supportive to feminist medical ethics because it focuses on the subscription to, and not merely the acceptance of, a particular view of morality. (shrink)

Newton deplored speculation in science, Einstein reveled in it. What exactly are scientific speculations? Are they ever legitimate? Are they subject to constraints? This book defends a pragmatic approach to these issues and applies it to speculations within science and to speculations about science.

Until recently most militaries tended to see moral issues through the lens of rules and regulations. Today, however, many armed forces consider teaching virtues to be an important complement to imposing rules and codes from above. A closer look reveals that it is mainly established military virtues such as honour, courage and loyalty that dominate both the lists of virtues and values of most militaries and the growing body of literature on military virtues. Although there is evidently still a role (...) for these traditional martial virtues, it is equally evident that they are not particularly relevant to, for instance, military personnel operating drones. This chapter looks into the ethics of unmanned warfare from the perspective of military virtues and military ethics education, and addresses the question of what we need to solve that just-mentioned misalignment: 1) a new set of virtues; 2) a different interpretation of the existing virtues; or 3) a different approach altogether, that is, an alternative to teaching virtues? That we have to think about such questions is at least partly because unmanned systems bring risk asymmetry in war to a new level, making warlike virtues such as physical courage by and large obsolete. The last section of this chapter therefore addresses the question: to what extent does the possibility of riskless warfare makes drone use ‘virtue-less’? (shrink)

This paper calls attention to a philosophical presupposition, coined here the continuity thesis which underlies and unites the different, often conflicting, hypotheses in the origin of life field. This presupposition, a necessary condition for any scientific investigation of the origin of life problem, has two components. First, it contends that there is no unbridgeable gap between inorganic matter and life. Second, it regards the emergence of life as a highly probable process. Examining several current origin-of-life theories. I indicate the implicit (...) or explicit role played by the continuity thesis in each of them. In addition, I identify the rivals of the thesis within the scientific community — the almost miracle camp. Though adopting the anti-vitalistic aspect of the continuity thesis, this camp regards the emergence of life as involving highly improbable events. Since it seems that the chemistry of the prebiotic stages and of molecular self-organization processes rules out the possibility that life is the result of a happy accident, I claim that the almost miracle view implies in fact, a creationist position.

Suppose you are stranded on an island and you want to get over to the nearby mainland. Your only option is to swim. But is the other shore close enough? If you embark and it isn’t, you drown. So you prefer to know before taking off. Happily, you are well equipped. You have not only a yardstick, but also a theodolite for measuring angles, and a good knowledge of trigonometry. You then determine the distance to the other shore by means (...) of triangulation. You fix two points, A and B, on your own shore, and identify a third point, C, in sight on the opposite shore. You then measure the distance between A and B with your yardstick, and the two angles ABC and CAB with your theodolite. With this information you can calculate the distances AC and BC to the other shore. (shrink)
