ObjectiveProcessing Speed, the ability to perceive and react fast to stimuli in the environment, has been shown to be impaired in children with attention deficit hyperactivity disorder. However, it is unclear whether PS can be improved following targeted treatments for ADHD. Here we examined potential changes in PS following application of transcranial electric stimulation combined with cognitive training in children with ADHD. Specifically, we examined changes in PS in the presence of different conditions of mental fatigue.MethodsWe used a randomized double-blind (...) active-controlled crossover study of 19 unmedicated children with ADHD. Participants received either anodal transcranial direct current stimulation over the left dorsolateral prefrontal cortex or transcranial random noise stimulation, while completing CT, and the administration order was counterbalanced. PS was assessed before and after treatment using the MOXO-CPT, which measures PS in the presence of various conditions of mental fatigue and cognitive load.ResultstRNS combined with CT yielded larger improvements in PS compared to tDCS combined with CT, mainly under condition of increased mental fatigue. Further improvements in PS were also seen in a 1-week follow up testing.ConclusionThis study provides initial support for the efficacy of tRNS combined with CT in improving PS in the presence of mental fatigue in pediatric ADHD.

© 2016 Elsevier LtdJumping spiders are famous for their visually driven behaviors [1]. Here, however, we present behavioral and neurophysiological evidence that these animals also perceive and respond to airborne acoustic stimuli, even when the distance between the animal and the sound source is relatively large and with stimulus amplitudes at the position of the spider of ∼65 dB sound pressure level. Behavioral experiments with the jumping spider Phidippus audax reveal that these animals respond to low-frequency sounds by freezing—a common (...) anti-predatory behavior characteristic of an acoustic startle response. Neurophysiological recordings from auditory-sensitive neural units in the brains of these jumping spiders showed responses to low-frequency tones —recordings that also represent the first record of acoustically responsive neural units in the jumping spider brain. Responses persisted even when the distances between spider and stimulus source exceeded 3 m and under anechoic conditions. Thus, these spiders appear able to detect airborne sound at distances in the acoustic far-field region, beyond the near-field range often thought to bound acoustic perception in arthropods that lack tympanic ears [2]. Furthermore, direct mechanical stimulation of hairs on the patella of the foreleg was sufficient to generate responses in neural units that also responded to airborne acoustic stimuli—evidence that these hairs likely play a role in the detection of acoustic cues. We suggest that these auditory responses enable the detection of predators and facilitate an acoustic startle response. Video. (shrink)

Intuition is frequently used in medicine. Along with the use of existing medical rules, there is a separate channel that physicians rely on when making decisions: their intuition. To cope with the epistemic problem of using intuition, I use some clues from Wittgenstein's philosophy to illuminate the decision-making process in medicine. First, I point to a connection between intuition as functioning in medicine and Wittgenstein's notions of "seeing as" or noticing "aspects". Secondly, I use Wittgenstein notion of empirical regularities hardened (...) into rules to suggest that there are two stages that should be addressed in the analysis of medical practice: the first concerns the accumulation of cases and the second pertains to the setting a rule based on these cases. I argue further that the medical context is exceptional in that the two stages are intertwined and, and explain the consequences of this fact for the physician's work. Finally, inspired by Wittgenstein's rule-following conundrum, I argue that medicine is particularly prone to difficulties in applying a general rule to a specific case represented by an individual patient. Recourse to intuition is reflects the physicians' efforts to bridge this gap. (shrink)

Asymmetrical convergence is the increasing overlap between academic and industrial sectors, but with academia moving closer toward for-profit industrial norms than vice versa. Although this concept, developed by Kleinman and Vallas, is useful, processes of asymmetrical convergence in daily laboratory life are largely unexplored. Here, observations of three lab groups of chemical scientists in academic and industry contexts illustrate variation in interactions with ethics-related policies. Findings show more tension for academic science with business-based practices, such as the move toward greater (...) accountability, than for industrial science with academic practices. This asymmetry is evident in the process of purposive decoupling: for example, where academic scientists use humor to distance themselves from the performance of compliance in required reporting and top-down ethics training requirements. This distancing from meaningless requirements contrasts with mentoring around practices of professional behavior that are thought to matter. Convergence is evident in how safety policies seem more engaging than other kinds of policies. Yet, power structures shape engagement. Academic engagement often means rule following, and flows vertically from professor’s authority to student apprenticeship. Industry engagement includes collaborative problem solving and flows along a more horizontal peer structure where informal power is less visible. (shrink)

:One view of practical reasoning is that it involves the weighing of reasons. It is not clear, however, how the weights of reasons combine, especially given the logical and substantive relations among different reasons. Nor is it clear how the weighing of reasons relates to decision theoretic maximization of expected value. This paper constructs a formal model of reasons and their weight in order to shed light on these issues. The model informs philosophical debates about reasons, such as the question (...) of whether reasons or values are more fundamental and the opposing doctrines of atomism and holism about reasons.

Objective: The purpose of this study was to demonstrate how educators involved in the teaching of bioethics to healthcare university students in Japan would cope with ethical disagreement in the classroom, and to identify factors influencing them.Methods: A cross sectional survey was conducted using self administered questionnaires mailed to a sample of university faculty in charge of bioethics curriculum for university healthcare students.Results: A total of 107 usable questionnaires were returned: a response rate of 61.5%. When facing ethical disagreement in (...) the classroom, coping behaviour differed depending on the topic of discussion, was influenced by educators’ individual clear ethical attitudes regarding the topic of discussion, and was independent of many respondents’ individual and social backgrounds. Among educators, it was commonly recognised that the purpose of bioethics education was to raise the level of awareness of ethical problems, to provide information about and knowledge of those issues, to raise students’ sensitivity to ethical problems, and to teach students methods of reasoning and logical argument. Yet, despite this, several respondents considered the purpose of bioethics education to be to influence students about normative ethical judgments. There was no clear relationship, however, between ways of coping with ethical disagreement and educators’ sense of the purpose of bioethics education.Conclusions: This descriptive study suggests that educators involved in bioethics education for healthcare university students in Japan coped in various ways with ethical disagreement. Further research concerning ethical disagreement in educational settings is needed to provide better bioethics education for healthcare students. (shrink)

This book presents G. A. Cohen's Gifford Lectures, delivered at the University of Edinburgh in 1996. Focusing on Marxism and Rawlsian liberalism, Cohen draws a connection between these thought systems and the choices that shape a person's life. In the case of Marxism, the relevant life is his own: a communist upbringing in the 1940s in Montreal, which induced a belief in a strongly socialist egalitarian doctrine. The narrative of Cohen's reckoning with that inheritance develops through a (...) series of sophisticated engagements with the central questions of social and political philosophy. In the case of Rawlsian doctrine, Cohen looks to people's lives in general. He argues that egalitarian justice is not only, as Rawlsian liberalism teaches, a matter of rules that define the structure of society, but also a matter of personal attitude and choice. Personal attitude and choice are, moreover, the stuff of which social structure itself is made. Those truths have not informed political philosophy as much as they should, and Cohen's focus on them brings political philosophy closer to moral philosophy, and to the Judeo-Christian ethical tradition, than it has recently been.

Students of perception have long puzzled over a range of cases in which perception seems to tell us distinct, and in some sense conflicting, things about the world. In the cases at issue, the perceptual system is capable of responding to a single stimulus — say, as manifested in the ways in which subjects sort that stimulus — in different ways. This paper is about these puzzling cases, and about how they should be characterized and accounted for within a general (...) theory of perception. After rehearsing the sort of case at issue (§1), I’ll examine critically some of the strategies by which philosophers and perceptual psychologists have attempted to account for them (§2). Finally, I’ll present an alternative computational account of the puzzle cases, argue that this view is superior to its competitors, and examine some of its implications (§3). (shrink)

Kant’s notorious remark about the impossibility of there ever being a Newton of a blade of grass has often been interpreted as a misguided pre-emptive strike against Darwin and evolutionary theories in general: 'It would be absurd for humans even to make such an attempt or to hope that there may yet arise a Newton who could make comprehensible even the generation of a blade of grass according to natural laws that no intention has ordered; rather, we must absolutely deny (...) this insight to human beings. (CPJ 5:400) My aim in this chapter is to re-evaluate this claim in the context of Kant’s account of organic generation and argue that, contrary to what is usually thought, it does leave room for the possibility of evolution. After spelling out the constraints Kant identifies for any scientific study of the history of living beings, I examine his theory of generation and draw its implications for biological heredity, species diversity, and the role played by environmental factors in organic development. On this basis, I conclude that first, evolution is a possible albeit far-fetched hypothesis for Kant; second, Darwin’s theory of natural selection would have turned a far-fetched possibility into a plausible candidate; and third, it would not have disposed of the need for teleology. This is why, I argue, Darwin could never have been a Newton of a blade of grass. (shrink)

Artificial intelligence (AI) has garnered tremendous attention in health care, and many hope that AI can enhance our health system’s ability to care for people with chronic and degenerative conditions, including Parkinson’s Disease (PD). This paper reports the themes and lessons derived from a qualitative study with people living with PD, family caregivers, and health care providers regarding the ethical dimensions of using AI to monitor, assess, and predict PD symptoms and progression. Thematic analysis identified ethical concerns at four intersecting (...) levels: personal, interpersonal, professional/institutional, and societal levels. Reflecting on potential benefits of predictive algorithms that can continuously collect and process longitudinal data, participants expressed a desire for more timely, ongoing, and accurate information that could enhance management of day-to-day fluctuations and facilitate clinical and personal care as their disease progresses. Nonetheless, they voiced concerns about intersecting ethical questions around evolving illness identities, familial and professional care relationships, privacy, and data ownership/governance. The multi-layer analysis provides a helpful way to understand the ethics of using AI in monitoring and managing PD and other chronic/degenerative conditions. (shrink)

Grammatical theories of Scalar Implicatures make use of an exhaustivity operator exh, which asserts the conjunction of the prejacent with the negation of excludable alternatives. We present a new Grammatical theory of Scalar Implicatures according to which exh is replaced with pex, an operator that contributes its prejacent as asserted content, but the negation of scalar alternatives at a non-at-issue level of meaning. We show that by treating this non-at-issue level as a presupposition, this theory resolves a number of empirical (...) challenges faced by the old formulation of exh (as well as by standard neo-Gricean theories). The empirical challenges include projection of scalar implicatures from certain embedded environments (‘some under some’ sentences, some under negative factives), their restricted distribution under negation, and the existence of common ground-mismatching and oddness-inducing implicatures. We argue that these puzzles have a uniform solution given a pex-based Grammatical theory of implicatures and some independently motivated principles concerning presupposition projection, cancellation and accommodation.

We live in a market system with much economic inequality. This may not be an essential characteristic of market systems but seems historically inevitable. How we should evaluate it, on the other hand, is contentious. I propose that bleeding heart libertarianism provides the best diagnosis and prescription.

Most scholars have not assigned much interpretive importance to the specific use of the term ‘persuasion’ in the cosmology of Plato’s Timaeus. This paper suggests understanding cosmological ‘persuasion’ in conjunction with ‘force,’ another trait of divine agency in the Timaeus. It analyses the nature of intelligent causation in the cosmology of the Timaeus, particularly in the construction of the cosmic body and soul. Then, it gives a detailed characterization of the causation of necessity, appearing in the Timaeus in three different (...) versions, and relates it to the complex notion of intelligent agency. Ultimately, it claims that the cosmic music in the Timaeus, the primary agent of ordered causation in the cosmos, functions on two levels of conflict with the disorder of the sensible aspect of the world.

Continuous first-order logic has found interest among model theorists who wish to extend the classical analysis of “algebraic” structures to various natural classes of complete metric structures. With research in continuous first-order logic preoccupied with studying the model theory of this framework, we find a natural question calls for attention. Is there an interesting set of axioms yielding a completeness result?The primary purpose of this article is to show that a certain, interesting set of axioms does indeed yield a completeness (...) result for continuous first-order logic. In particular, we show that in continuous first-order logic a set of formulae is satisfiable if it is consistent. From this result it follows that continuous first-order logic also satisfies an approximated form of strong completeness, whereby Σ⊨φ only if Σ⊢φ∸ 2-n for all n < ω. This approximated form of strong completeness asserts that if Σ⊨φ, then proofs from Σ, being finite, can provide arbitrarily better approximations of the truth of φ.Additionally, we consider a different kind of question traditionally arising in model theory—that of decidability. When is the set of all consequences of a theory recursive? Say that a complete theory T is decidable if for every sentence φ, the value φT is a recursive real, and moreover, uniformly computable from φ. If T is incomplete, we say it is decidable if for every sentence φ the real number φT∘ is uniformly recursive from φ, where φT∘is the maximal value of φ consistent with T. As in classical first-order logic, it follows from the completeness theorem of continuous first-order logic that if a complete theory admits a recursive axiomatization then it is decidable. (shrink)

Sentences such as Olivia can take Logic or Algebra (‘♢∨-sentences’) are typically interpreted as entailing that Olivia can take Logic and can take Algebra. Given a standard semantics for modals and disjunction, those ‘Free choice’ (FC) readings are not predicted from the surface form of ♢∨-sentences. Yet the standard semantics is appropriate for the ‘double prohibition’ reading typically assigned to ¬♢∨-sentences like Olivia can’t take Logic or Algebra. Several extant approaches to FC can account for those two cases, but face (...) challenges when ♢∨, ¬♢∨ and related sentences appear embedded in certain environments. In this paper, we present a novel account of FC that builds on a ‘grammatical’ theory of scalar implicatures — proposed by Bassi et al. (2021) and Del Pinal (2021) — according to which covert exhaustification is a presupposition trigger such that the prejacent forms the assertive content while any excludable or includable alternatives are incorporated at the non-at issue, presuppositional level. Applied to ♢∨, ¬♢∨, and similar sentences, ‘presuppositional exhaustification’ predicts that their default interpretations have an assertive component (roughly, the classical interpretation of the prejacent) and a homogeneity presupposition which projects in standard ways. Those predictions, we then show, support a uniform account of the puzzling behavior of ♢∨, ¬♢∨, and related sentences when embedded under (negative) factives (Marty & Romoli 2020), disjunctions (Romoli & Santorio 2019), and in the scope of universal, existential (Bar-Lev & Fox 2020) and non-monotonic quantifiers (Gotzner et al. 2020).

Wes Morriston contends that William Lane Craig's argument for the impossibility of a beginningless past results in an equally good argument for the impossibility of an endless future. Craig disagrees. I show that Craig's reply reveals a commitment to an unmotivated position concerning the relationship between actuality and the actual infinite. I then assess alternative routes to the impossibility of a beginningless past that have been offered in the literature, and show that, contrary to initial appearances, these routes similarly seem (...) to support the impossibility of an endless future.

We give a general framework for the treatment of perturbations of types and structures in continuous logic, allowing to specify which parts of the logic may be perturbed. We prove that separable, elementarily equivalent structures which are approximately $aleph_0$-saturated up to arbitrarily small perturbations are isomorphic up to arbitrarily small perturbations. As a corollary, we obtain a Ryll-Nardzewski style characterisation of complete theories all of whose separable models are isomorphic up to arbitrarily small perturbations.

Counseling Ethics for the 21st Century prepares students to address ethical issues arising in contemporary counseling practice. Drawing on their own clinical and practical experiences, authors Elliot D.

Each chapter focuses on particular virtues in the context of examining a particular counseling issue, including online counseling, (...) digital record keeping, and social media. Students will be empowered to define problems, identify relevant facts, conduct ethical analyses, and make the best decisions for their clients. (shrink)

This book examines Aristotle's metaphysics and his account of nature, stressing the ways in which his desire to explain observed natural processes shaped his philosophical thought. It departs radically from a tradition of interpretation, in which Aristotle is understood to have approached problems with a set of abstract principles in hand, principles derived from critical reflection on the views of his predecessors. A central example of the book interprets Aristotle's essentialism as deriving from an examination of the kinds of unity (...) that various sorts of things have: elemental motion, alteration, transformation and the growth of organisms. An important conclusion of this argument is that an essence may, under certain circumstances, lack some of its essential attributes. This is a major re-evaluation of Aristotle's metaphysics that will interest philosophers, classicists and historians of science. (shrink)

We present an adaptation of continuous first order logic to unbounded metric structures. This has the advantage of being closer in spirit to C. Ward Henson's logic for Banach space structures than the unit ball approach, as well as of applying in situations where the unit ball approach does not apply. We also introduce the process of single point emph{emboundment}, allowing to bring unbounded structures back into the setting of bounded continuous first order logic. Together with results from cite{BenYaacov:Perturbations} regarding (...) perturbations of bounded metric structures, we prove a Ryll-Nardzewski style characterisation of theories of Banach spaces which are separably categorical up to small perturbation of the norm. This last result is motivated by an unpublished result of Henson. (shrink)

Questions about the ontology of color matter because colors matter. Colors are extremely pervasive and salient features of the world. Moreover, people care about the distribution of these features: they expend money and effort to paint their houses, cars, and other possessions, and their clear preference for polychromatic over monochromatic televisions and computer monitors have consigned monochromatic models to the status of rare antiques. The apparent ubiquity of colors and their importance to our lives makes them a ripe target for (...) ontological questions such as the following: " • What is the nature of colors?

In this project, we assessed 242 codes of media ethics from 94 countries across the globe, focusing on their treatment of moonlighting. The analysis included whether the codes dealt with moonlighting, whether geopolitical and geoeconomic characteristics affected the treatment of the issue, and whether the type of media organization was significant. Only about half the codes addressed moonlighting; Eastern European countries paid the greatest attention to moonlighting, and newspapers and chains were more likely than other media organizations to deal with (...) the issue. Overall, it appears that codes of ethics do not provide clear, strict, or consistent guidelines. (shrink)

Clinical ethics support, including ethics consultation, has become established in the field of medical practice throughout the world. This practice has been regarded as useful, most notably in the UK and the USA, in solving ethical problems encountered by both medical practitioners and those who receive medical treatment. In Japan, however, few services are available to respond to everyday clinical ethical issues, although a variety of difficult ethical problems arise daily in the medical field: termination of life support, euthanasia and (...) questions about patient autonomy. In light of these conditions, a group of 17 volunteer educators and researchers from the area of biomedical ethics, including the authors, have formed the Clinical Ethics Support and Education Project, and began providing Japan’s first small team clinical ethics consultation service in October, 2006. Members include scholars of biomedical ethics, scholars of philosophy and ethics, legal professionals and legal scholars, nurses and doctors, consisting of five women and 12 men. Consultation teams, made up of a small number of members, were organised each time a request for consultation was received. Over approximately 15 months (October 2006–December 2007), the programme received 22 consultation requests from medical practitioners and medical institutions, and three from the families of patients. In this paper, we will discuss the status of our consultation service and examples of consultation cases we have handled. In addition, we will examine the process of evaluating small team clinical ethics consultation services, as well as the strengths and weakness of such programmes. (shrink)

Artificial intelligence (AI) technologies in medicine are gradually changing biomedical research and patient care. High expectations and promises from novel AI applications aiming to positively impact society raise new ethical considerations for patients and caregivers who use these technologies. Based on a qualitative content analysis of semi-structured interviews and focus groups with healthcare professionals (HCPs), patients, and family members of patients with Parkinson’s Disease (PD), the present study investigates participant views on the comparative benefits and problems of using human versus (...) AI predictive computer vision health monitoring, as well as participants’ ethical concerns regarding these technologies. Participants presumed that AI monitoring would enhance information sharing and treatment, but voiced concerns about data ownership, data protection, commercialization of patient data, and privacy at home. They highlighted that privacy issues at home and data security issues are often linked and should be investigated together. Findings may help technologists, HCPs, and policymakers determine how to incorporate stakeholders’ intersecting but divergent concerns into developing and implementing AI PD monitoring tools.

It is well-known that in the fifth of his Cartesian Meditations, Husserl puts forth a theory of intersubjectivity. Most commentators of Husserl have read his Cartesian Meditations as presenting a theory of intersubjectivity whose basis is empathy, in the form of a process of constituting the sense of “other” in one’s own experience, as the primary origin of the intersubjective layer of experience. In this paper, I claim that the structure of intersubjectivity as Husserl presents it in the Cartesian Meditations (...) is articulated as being governed by a logic of parts and wholes rather than that of a phenomenology of empathy, and that the articulation of this logic demonstrates that the transcendental ego is intrinsically intersubjective. My main philosophical claim in this regard is that the way Husserl’s account of transcendental empathy unfolds in the Cartesian Meditations implies a prior fundamental mereological structure of which the individual transcendental ego is only a part. That is, the transcendental ego has an eidetic a-priori intersubjective structure, in the sense of being a moment of an intersubjectively structured transcendental whole. In this sense, rather than being a singulare tantum, it is more fitting to say that transcendental subjectivity is actually a plurale tantum. (shrink)

We point out how the "Fundamental Theorem of Stability Theory", namely the equivalence between the "non order property" and definability of types, proved by Shelah in the 1970s, is in fact an immediate consequence of Grothendieck's "Criteres de compacite" from 1952. The familiar forms for the defining formulae then follow using Mazur's Lemma regarding weak convergence in Banach spaces.

In Mindblindness, Simon Baron-Cohen presents a model of the evolution and development of "mindreading." He argues that we mindread all the time, effortlessly, automatically, and mostly unconsciously. It is the natural way in which we interpret, predict, and participate in social behavior and communication. We ascribe mental states to people: states such as thoughts, desires, knowledge, and intentions. Building on many years of research, Baron-Cohen concludes that children with autism, suffer from "mindblindness" as a result of a selective (...) impairment in mindreading. For these children, the world is essentially devoid of mental things. Baron-Cohen develops a theory that draws on data from comparative psychology, from developmental, and from neuropsychology. He argues that specific neurocognitive mechanisms have evolved that allow us to mindread, to make sense of actions, to interpret gazes as meaningful, and to decode "the language of the eyes."

The characteristic focus, intensity and hopefulness of Noam Chomsky's political writings reflect a set of more fundamental views about human nature, justice and social order that are not simple matters of fact. This chapter explores these more fundamental ideas, the central elements in Chomsky's social thought. Chomsky's own conception of human nature draws together a romantic emphasis on the distinctive human capacity for creative expression and a rationalist contention that there is an intrinsic and determinate structure to the human mind. (...) According to Chomsky, the “fundamental fact about the normal use of language” is its “creative aspect’. The linguistic knowledge expressed in such creativity is acquired by virtually all human beings in a short period of time, and in the face of unstructured and impoverished inputs from the environment. The chapter examines his libertarian social ideals and views on social stability and social evolution, both of which are animated by this conception of our nature. (shrink)
