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)

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)

Depression is associated with increased maintenance of negative affect (NA) and reduced – blunted and short-lived – maintenance of positive affect (PA). Studies have focused on factors associated with the maintenance of NA, specifically, the emotion regulation strategy of brooding and the capacity to hold negative affective experiences in working memory (WM). Despite its theoretical importance, less attention has been given to factors associated with the maintenance of PA in depression. This study aims to synthesise factors playing a role in (...) the maintenance of both NA and PA. Specifically, we used self-reported assessment of PA and NA regulation and performance-based measures of NA and PA processing in WM to predict depressive symptoms severity. Participants (N = 219) completed the Affective Maintenance Task (AMT, Mikels et al., Citation2008), which provided performance-based measures of PA and NA maintenance, and filled out questionnaires assessing brooding, positive rumination and depressive severity. Brooding, positive rumination and AMT-based measures of positive (but not negative) affective information processing were independently associated with depressive symptoms. We highlight the unique contributions of PA processing, as well as of self-reported emotion regulation strategies in understanding depression maintenance. (shrink)

-/- Continuous first-order logic has found interest among model theorists who wish to extend the classical analysis of “algebraic” structures (such as fields, group, and graphs) to various natural classes of complete metric structures (such as probability algebras, Hilbert spaces, and Banach spaces). 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 (completely) satisfiable if (and only 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 (if and) 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 (in a countable, recursive language) recursive? Say that a complete theory T is decidable if for every sentence φ, the value φ T 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 φ T o is uniformly recursive from φ, where φ T o 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 (or even recursively enumerable) axiomatization then it is decidable.

: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.

Questionnaire data obtained from 97 supervisory and nonsupervisory employees representing the Production, Production Services, Marketing, and Administration departments of an Israeli metal production plant were used to test the relationship between selected personal and organizational attributes and work related misbehavior. Following Vardi and Wiener''s (1996) framework, Organizational Misbehavior (OMB) was defined as intentional acts that violate formal core organizational rules. We found that there was a significant negative relationship between Organizational Climate and OMB, and between the Organizational Climate dimensions (...) (Warmth and Support, and Reward), and OMB. Also, the activities of misbehavior reported by both managers and employees were negatively related to the Rules, Instrumental and Caring dimensions of Ethical Climates as defined by Victor and Cullen (1988).

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)

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.

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.

We prove that for every simple theory $T$ (or even simple thick compact abstract theory) there is a (unique) compact abstract theory $T^fP$ whose saturated models are the lovely pairs of $T$. Independence-theoretic results that were proved in [Ben Yaacov, Pillay, Vassiliev - Lovely pairs of models] when $T^fP$ is a first order theory are proved for the general case: in particular $T^fP$ is simple and we characterise independence.

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)

We prove that the definition of supersimplicity in metric structures from [Ben Yaacov, Uncountable dense categoricity in cats] is equivalent to an textit{a priori} stronger variant. This stronger variant is then used to prove that if $T$ is a supersimple Hausdorff cat then so is its theory of lovely pairs.

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.

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)

La présente étude souligne que l’idée de gouvernance de Bentham avait déjà été formulée dans les années 1780 et explique clairement que ses idées étaient cohérentes, en prenant en compte l’interprétation de Schofield concernant la radicalisation progressive de Bentham.

Basées sur Fragment sur le gouvernement et sur Introduction aux principes de la morale et de la législation dans les années 1770, diverses idées, dont la théorie de la « législation indirecte » de Bentham dans les années 1780, se concrétisèrent par son idée utilitariste de gouvernement.

We give a model-theoretic account for several results regarding sequences of random variables appearing in Berkes and Rosenthal [12]. In order to do this,•We study and compare three notions of convergence of types in a stable theory: logic convergence, i.e., formula by formula, metric convergence (both already well studied) and convergence of canonical bases. In particular, we characterise א0-categorical stable theories in which the last two agree.•We characterise sequences that admit almost indiscernible sub-sequences.•We apply these tools to the theory of (...) atomless random variables (ARV). We characterise types and notions of convergence of types as conditional distributions and weak/strong convergence thereof, and obtain, among other things, the Main Theorem of Berkes and Rosenthal.

The notion of quasi-minimal structures was defined by B. Zil'ber as a natural generalization of minimal structures. Inspired by his work, we study here basic model theoretic properties of quasiminimal structures. Main result is the construction of ω-saturated quasi-minimal models under ω-stability assumption.

We study the following conjecture. Conjecture. Let T be an ω-stable theory with continuum many countable models. Then either i) T has continuum many complete extensions in L1(T), or ii) some complete extension of T in L1 has continuum many L1-types without parameters. By Shelah's proof of Vaught's conjecture for ω-stable theories, we know that there are seven types of ω-stable theory with continuum many countable models. We show that the conjecture is true for all but one of these seven (...) cases. In the last case we show the existence of continuum many L2-types. (shrink)

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.

Vardi, M.Y., Verification of concurrent programs: the automata-theoretic framework, Annals of Pure and Applied Logic 51 79–98. We present an automata-theoretic framework to the verification of concurrent and nondeterministic programs. The basic idea is that to verify that a program P is correct one writes a program A that receives the computation of P as input and diverges only on incorrect computations of P. Now P is correct if and only if a program PA, obtained by combining P and (...) A, terminates. We formalize this idea in a framework of ω-automata with a recursive set of states. This unifies previous works on verification of fair termination and verification of temporal properties. (shrink)

If ${\mathfrak {F}}$ is a type-definable family of commensurable subsets, subgroups or subvector spaces in a metric structure, then there is an invariant subset, subgroup or subvector space commensurable with ${\mathfrak {F}}$. This in particular applies to type-definable or hyper-definable objects in a classical first-order structure.

Given a continuous and isometric action of a Polish group G on an adequate Polish topometric space $(X,\tau,\rho )$ and $x \in X$, we find a necessary and sufficient condition for $\overline {Gx}^{\rho }$ to be co-meagre; we also obtain a criterion that characterizes when such a point exists. This work completes a criterion established in earlier work of the authors.

For a locally compact group G, we show that it is possible to present the class of continuous unitary representations of G as an elementary class of metric structures, in the sense of continuous logic. More precisely, we show how nondegenerate ∗-representations of a general ∗-algebra A (with some mild assumptions) can be viewed as an elementary class, in a many-sorted language, and use the correspondence between continuous unitary representations of G and nondegenerate ∗-representations of L1(G). We relate the notion (...) of ultraproduct of logical structures, under this presentation, with other notions of ultraproduct of representations appearing in the literature, and we characterize property (T) for G in terms of the definability of the sets of fixed points of L1 functions on G.

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.

Vardy (philosophy, U. of London) summarizes the main features of many of the central debates concerning God's reality and how God is to be understood.

The argument from inductive risk claims that judgments about the moral severity of errors are relevant to decisions about what should count as sufficient evidence for accepting claims. While this idea has been explored in connection with evidence required for the approval of pharmaceuticals, the role of inductive risk in the post-approval process has been largely neglected. In this article, we examine the ethics of inductive risk in connection with revisions to the product monograph for OxyContin in Canada, which understates (...) the risks of addiction and abuse associated with this drug. Using the concept of inductive risk, we consider what evidence should have been sufficient for Health Canada to revise the product monograph for OxyContin. Given the stakes involved, we argue that a less strict standard of evidence would have been appropriate, yet HC in fact took the opposite course, insisting upon a higher standard of evidence than it normally requires. In addition to providing a novel perspective on the opioid crisis in Canada, this article contributes to existing philosophical work by demonstrating that inductive risks in the post-approval stage are important and linked to pre-approval inductive risks.

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).

In Book 19, chapter 9 of the Nodes Atticae Gellius describes the birthday party of a young Greek of equestrian rank at which a group of professional singers entertained the guests by performing poems by Anacreon, Sappho, ‘et poetarum quoque recentium λεγεα quaedam erotica’ . After the singing, Gellius goes on, some of the Greek συμπόται present challenged Roman achievements in erotic poetry, excepting only Catullus and Calvus, and criticized in particular Laevius, Hortensius, Cinna, and Memmius. Rising to meet this (...) charge, Gellius’ teacher of rhetoric, Antonius Julianus, admits the superiority of the Greeks in what he calls ‘cantilenarum mollitiae’ in general , but to show that the Romans too have some good erotic poets, he recites four early Latin love epigrams, by Valerius Aedituus , Porcius Licinus , and Lutatius Catulus . The same three poets are listed in the same order in Apuleius’ Apology in a list of amatory poets which he provides in order to establish precedents and thus invalidate his prosecutors’ referral to his erotic poems in their accusation . Catulus is also enumerated in Pliny's list of Roman dignitaries who composed ‘uersiculos seueros parum’ like his own , and an amatory epigram of his is cited by Cicero in De Natura Deorum 1.79 . We possess no further evidence connecting the other two with the composition of either erotic or, more generally, ‘light’ verse, but a poem by Porcius Licinus on Roman literary history is attested by several sources including Varro, Suetonius, and Gellius himself.
