The tsunami effect of the COVID-19 pandemic is affecting many aspects of scientific activities. Multidisciplinary experimental studies with international collaborators are hindered by the closing of the national borders, logistic issues due to lockdown, quarantine restrictions, and social distancing requirements. The full impact of this crisis on science is not clear yet, but the above-mentioned issues have most certainly restrained academic research activities. Sharing innovative solutions between researchers is in high demand in this situation. The aim of this paper is (...) to share our successful practice of using web-based communication and remote control software for real-time long-distance control of brain stimulation. This solution may guide and encourage researchers to cope with restrictions and has the potential to help expanding international collaborations by lowering travel time and costs. (shrink)

The paper develops a new holistic theory of the word by integrating semiotic, linguistic, and psychological perspectives and introduces the Cogitative-Sensory Word Model, the CogSens Model, that unites the human mind and body. Saussure’s two-sided sign is replaced by a Peirce-inspired three-sided conception in which the expression unit mediates two content units, namely, an idea content connected to the human mind and an image content linked to the human body. It is argued that it is the word that makes human (...) language a unique tool of communication. Moreover, it is demonstrated how words interact with grammar to create an utterance. Finally, it is suggested that speech perception, i.e., fission of idea and image content, is the mirror image of speech production, i.e., fusion of idea and image content. (shrink)

The book deals with the notion of Downward Causation from a wide array of perspectives, including physics, biology, psychology, social science, communication studies, text theory, and philosophy. The book includes proponents as well as opponents discussing the validity of the notion.

We use recent developments within philosophy of science and within certain strands of linguistic research to throw light on each other. According to Ronald Giere's perspectivist philosophy of science, the scientific understanding of reality must proceed along different, mutually irreducible lines of approach. Giere's proposal, however, leaves unresolved the problem of how to integrate the ever‐growing multitude of highly diverse scientific accounts of what is, after all, one and the same world. We propose a technique for the alignment of different (...) perspectives that will permit cross‐perspectival explanation, and thus allow for a more holistic picture of reality to emerge. With respect to modern linguistics, however, Giere's perspectivism merely legalises a de facto state of affairs, as this discipline displays the peaceful coexistence of a multitude of different theoretical perspectives. Still, this makes it all the more important to show how the different aspects of language picked out by these different perspectives combine to form one single complex reality. During our investigation, a largely overlooked type of reduction within linguistics comes to light, prevalent in classical as well as current work within speech act theory and politeness theory. We suggest how a more holistic understanding of language can be attained through our technique for integrating different perspectives. (shrink)

Wenn digitale Technologien wie künstliche Intelligenz, Blockchain und Robotik auf die Medizin treffen, entstehen zwangsläufig ethische Fragestellungen. Diese lassen sich nicht ohne Weiteres mit medizinisch-technologischen, rechtlichen oder ökonomischen Argumenten allein beantworten. Neue Themenfelder wie die sich wandelnde Rolle der Patienten, die neue Verantwortung von Ärzten und Pflegenden, neue digitale Möglichkeiten in der Medizin, Smart Hospitals im Klinikalltag, die gesellschaftliche Legitimität eines möglichen dritten Datengesundheitsmarktes, eine zukunftsfeste Ausbildungslandschaft für den Gesundheits-/Medizinbereich sowie die Grenzen der digitalen Forschung bedürfen einer kritischen und gleichzeitig (...) thematisch breiten Auseinandersetzung mit ethischen Aspekten in der digitalen Gesundheitswirtschaft und Medizin.

This paper explores the laborious and intimate work of turning bodies of research animals into models of human patients. Based on ethnographic research in the interdisciplinary Danish research centre NEOMUNE, we investigate collaboration across species and disciplines, in research aiming at improving survival for preterm infants. NEOMUNE experimental studies on piglets evolved as a platform on which both basic and clinical scientists exercised professional authority. Guided by the field of multi-species research, we explore the social and material agency of research (...) animals in the production of human health. Drawing on Anna Tsing’s concept of “collaborative survival”, we show that sharing the responsibility of the life and death of up to twenty-five preterm piglets fostered not only a collegial solidarity between basic and clinical scientists, but also a transformative cross-fertilization across species and disciplines—a productive “contamination”—facilitating the day-to-day survival of piglets, the academic survival of scientists and the promise of survival of preterm infants. Contamination spurred intertwined identity shifts that increased the porosity between the pig laboratory and the neonatal intensive care unit. Of particular significance was the ability of the research piglets to flexibly become animal-infant-patient hybrids in need of a united effort from basic and clinical researchers. However, ‘hybrid pigs’ also entailed a threat to the demarcation between humans and animals that consolidates the use of animals in biomedical research, and efforts were continuously done to keep contamination within spatial limits. We conclude that contamination facilitates transformative encounters, yet needs spatial containment to materialize bench-to-bedside translation. (shrink)

The paper reviews the current state of play around anti-representationalist attempts at countering Clark and Toribio’s representation-hunger thesis. It introduces a distinction between different approaches to Chemero’s Radical embodied cognition thesis in the form of, on the one hand, those pushing a hard line and, on the other, those who are more relaxed about their anti-representationalist commitments. In terms of overcoming Clark and Toribio’s thesis, hardliners seek to avoid any mentioning of mental content in the activity they purport to explain. (...) Yet, the paper argues, adopting a hard line complicates this endeavor considerably and unnecessarily. Those promoting a relaxed REC, however, are better off in that they have no problem in recognizing that some types of cognition are hybrid. By turning to Hutto and Myin’s Radical Enactivism as a prime example of a relaxed approach to the REC thesis, the paper points towards the lack of continuity between covariant information and informational content as the gap that would necessarily have to be closed in order for RECers to, once and for all, be able to dismiss Clark and Toribio’s hypothesis that certain kinds of cognition are per definition off-limits to anti-representationalism.

The reduction of grounding to causation, or each to a more general relation of which they are species, has sometimes been justified by the impressive inferential capacity of structural equation modelling, causal Bayes nets, and interventionist causal modelling. Many criticisms of this assimilation focus on how causation is inadequate for grounding. Here, I examine the other direction: how treating grounding in the image of causation makes the resulting view worse for causation. The distinctive features of causal modelling that make this (...) connection appealing are distorted beyond use by forcing them to fit onto grounding. The very inferential strength that makes causation attractive is only possible because of a narrow construal of what counts as a causal relation; as soon as that broadens, the inferential capacity markedly diminishes. Making causation suitable for application to grounding spoils what was appealing about causation for this task in the first place. However, grounding need not appeal to causation: causal modelling does not have exclusive claim to structural equation modeling or other formal techniques of modelling structure. I offer a case in favour of a different kind of metaphysical frugality, which tend towards narrow, more restrictive construals of relations like causation or grounding, because then each relation behaves more homogenously. This more homogenous behavior delivers stronger inferential power per relation even though there may be more relations to which one is committed. (shrink)

Obesity continues to be a global issue. In recent years, researchers have started to question the role of our novel yet ubiquitous use of digital media in the development of obesity. With the recent COVID-19 outbreak affecting almost all aspects of society, many people have moved their social eating activities into the digital space, making the question as relevant as ever. The bombardment of appetizing food images and photography – colloquially referred to as “food porn” – has become a significant (...) aspect of the digital food experience. This review presents an overview of whether and how the viewing, creating, and online sharing of digital food photography can influence consumer eating behavior. Moreover, this review provides an outlook of future research opportunities, both to close the gaps in our scientific understanding of the physiological and psychological interaction between digital food photography and actual eating behavior, and, from a practical viewpoint, to optimize our digital food media habits to support an obesity-preventive lifestyle. We do not want to rest on the idea that food imagery’s current prevalence is a core negative influence per se. Instead, we offer the view that active participation in food photography, in conjunction with a selective use of food-related digital media, might contribute to healthy body weight management and enhanced meal pleasure.

Un problème important à propos de l’incommensurabilité est d’expliquer comment des théories qui sont incommensurables peuvent néanmoins entrer en compétition. Dans cet article, on examine brièvement le compte rendu kuhnien de la différence entre transitions conceptuelles révolutionnaires et non révolutionnaires. On argue que l’approche taxonomique kuhnienne et le principe de non-recouvrement qui le sous-tend ne suffisent pas à distinguer entre ces deux types de transition. On montre que cette approche s’appuie principalement sur des analyses de corrélations entre traits, alors qu’il (...) est nécessaire de prendre de plus en considération les explications en vigueur de ces corrélations entre traits. Ceci met l’accent sur les théories, un élément qui n’a joué qu’un rôle modeste dans le travail que Kuhn a consacré aux lexiques scientifiques des années 1980 au début des années 1990. On argue que sur la base de ce compte rendu élargi des structures conceptuelles, l’incommensurabilité correspond à des corrélations qui d’un côté portent sur des traits présentant des recouvrements et de l’autre sont subsumées sous des explications différentes.

A. N. Prior’s writings should obviously be studied already for historical reasons. His inventions of modern temporal logic and hybrid logic are clearly important events in the history of logic. But the enduring importance of studying his works also rests on his methodological approach, which remains highly relevant also for systematical reasons. In this paper we argue that Prior’s formulation in the 1950s of a tense-logical paradigm for the study of time should be understood in the light of at least (...) three other principles or perspectives which were manifest already in his studies during the 1940s and further developed in the 1950s: his emphasis on the value of interdisciplinary studies, his reflections on formalisation and his view of the role of symbolic logic in conceptual studies and in the philosophy of science. Our investigation into Prior’s basic tenets and principles makes extensive use of Prior’s Nachlass. It is thereby also exemplified how his correspondence and unpublished papers contain important information for a deeper understanding of Prior’s paradigm for the study of time. (shrink)

Ethical approval must be obtained before medical research can start. We describe the differences in EA for an pseudonymous, non-interventional, observational European study. Sixteen European national coordinators of the international study on very old intensive care patients answered an online questionnaire concerning their experience getting EA. N = 8/16 of the NCs could apply at one single national ethical committee, while the others had to apply to various regional ECs and/or individual hospital institutional research boards. The time between applying for (...) EA and the first decision varied between 7 days and 300 days. In 9/16 informed consent from the patient was not deemed necessary; in 7/16 informed consent was required from the patient or relatives. The upload of coded data to a central database required additional information in 14/16. In 4/16 the NCs had to ask separate approval to keep a subject identification code list to de-pseudonymize the patients if questions would occur. Only 2/16 of the NCs agreed that informed consent was necessary for this observational study. Overall, 6/16 of the NCs were satisfied with the entire process and 8/16 were unsatisfied. 11/16 would welcome a European central EC that would judge observational studies for all European countries. Variations in the process and prolonged time needed to get EA for observational studies hampers inclusion of patients in some European countries. This might have a negative influence on the external validity. Further harmonization of ethical approval process across Europe is welcomed for low-risk observational studies. Getting ethical approval for low-risk, non-interventional, observational studies varies enormously across European countries. (shrink)

Process metaphysics (process philosophy) has been suggested as a route, to a more ‘processbased’ approach to organizational studies, as opposed to a ‘substance-based’ view said to be dominant in Western thinking — including most contemporary organizational researchers. This paper explores some of the ideas of early-twentieth-century process thinkers and provides an interpretation of some of the major works of Alfred N. Whitehead. The objective is to evaluate its possible relevance to modern organizational research. The paper argues that Whitehead’s radical ontology (...) — that was based on a generalization of quantum theory in physics — appears largely to have been refuted or disregarded by succeeding process philosophers. Furthermore, his epistemology is found to represent a process view on scientific knowledge creation taken for granted by most contemporary researchers. For different reasons, major elements of his theories do not appear to be directly relevant to efforts to advance organizational theory into more radical process-based theories. On the other hand, the paper argues that the early-twentieth-century process thinkers — including Whitehead — offer a plurality of analytical conceptions that may serve as useful and inspirational contributions to further development of methods and perspectives to investigate into organizations, change and innovation processes. There are also particular approaches within the domain that have properties quite similar to some of those conceptions in process philosophy — like ‘sensemaking processes’ as represented by Karl Weick and others, which may in particular benefit from exploring the area of process philosophy.

Arthur Norman Prior's early theological writings have been relatively neglected for many years. Moreover, to the extent that they have been discussed at all they have been treated mainly as youthful work quite separate from Prior's later work as a philosopher and logician. However, as interest in Prior's achievements has been growing significantly in recent years it has become more important to investigate the development with his overall work. In fact, Prior's putatively "youthful" theological work overlapped his work as a (...) philosopher and logician for many years, as is richly documented by examples discussed in this paper. A particularly important theme is the problem of predestination. This paper presents comprehensive evidence that this theme, which was Prior's most important single preoccupation as a theological writer, was a most important source of inspiration for his development of tense logic. Via questions regarding divine foreknowledge and human free will, predestination was to motivate Prior as a logician to focus on time and tense. Whilst investigating this development, the paper also traces Prior's parallel development from Calvinist Christian believer to a more agnostic position. (shrink)

Improving on a result of Arana, we construct an effective family (φ r | r ∈ ℚ ⋂ [0, 1]) of Σ n -conservative Π n sentences, increasing in strength as r decreases, with the property that ¬φ p is Π n -conservative over PA + φ q whenever p < q. We also construct a family of Σ n sentences with properties as above except that the roles of Σ n and Π n are reversed. The latter result allows (...) to re-obtain an unpublished result of Solovay, the presence of a subset order-isomorphic to the reals in every non-trivial end-segment of every branch of the E-tree, and to generalize it to analogues of the E-tree at higher levels of the arithmetical hierarchy.

Arthur Norman Prior (1914-69) was a logician and philosopher from New Zealand who contributed crucially to the development of ‘non-standard’ logics, especially of the modal variety. His greatest achievement was the invention of modern temporal logic, worked out in close connection with modal logic. However, his work in logic had a much broader scope. He was also the founder of hybrid logic, and he made important contributions to deontic logic, modal logic, the theory of quantification, the nature of propositions and (...) the history of logic. In addition, he discussed questions of ethics, free will, and general theology. Prior’s philosophical works comprise about 200 titles. His earliest articles center on philosophical theology and historical studies of Scottish Reformed Theology. This led on to the publication of his first influential work on ethics: Logic and The Basis of Ethics (1949). With the invention of tense-logic in the early 1950s, his focus shifted to investigations into the syntax of tempo-modal logic leading to his seminal Time and Modality (1957), a volume derived from his John Locke Lectures in Oxford in 1956. Furthermore Prior, together with the Irish mathematician and logician C.A. Meredith (1904-76), made important early contributions to the semantics of possible worlds. Prior’s tense-logic provided a strong conceptual framework for problems pertaining to the philosophy of time. In Time and Modality, Prior discussed the philosophical implications of Ruth Barcan’s famous formulae for tense-logic, and in the 1960s he worked on the notion of the present. The most persistent problem running through Prior’s work is his study of the questions surrounding human freedom and divine foreknowledge, and more general philosophical problems emerging from this classical theological question. His thorough analysis of this problem, with the conceptual tools of tense-logic, received a crucial impetus from his correspondence with the young Saul Kripke, when the latter suggested the semantic tool of branching time to Prior. Prior’s development of two solutions based on branching time for the problem of future contingency, the Peircean and the Ockham solution, was most thoroughly developed in Past, Present and Future (1967), the most important work published by Prior. Characteristically for Prior’s methodological approach, the development of these two solutions were at the same time a development of two new systems of tense logic, and vice versa. One of Prior’s significant contributions to logic was his work on world propositions and instant propositions. In the course of developing these notions he also made one of the earliest formulations of hybrid logic. In Papers on Time and Tense (1968), he presented this idea in a more detailed manner in the context of his four grades of tense-logical involvement. (shrink)

Open peer commentary on the article “Interactivity and Enaction in Human Cognition” by Matthew Isaac Harvey, Rasmus Gahrn-Andersen & Sune Vork Steffensen. Upshot: To sort out their differences with enactive theory, interactivity theorists would do better to focus on operational closure only insofar as it constitutes a condition of intrinsic normativity or self-regulated coupling.

A descriptive, cross-sectional study aimed to determine the inclination of nursing students towards ethical values and the effects of these values on care behaviours. The data for this study were collected from 466 students studying from May 13–24, 2019. The data were collected using a questionnaire on the sociodemographic characteristics of the students, Inclination to Ethical Values Scale (IEVS), and Caring Behaviors Inventory-24 (CBI-24). In this study, 43.1 per cent of them belonged to families who had a protective attitude. The (...) total mean (SD) IEVS and CBI-24 scores were 63.99 (12.68) and 117.19 (17.95), respectively. The mean item score was 4.88 (0.74). A moderate positive correlation was observed between the inclination of the students towards ethical values and their care behaviours. The general family structure of the nursing students and their participation in an ethics class affected the inclination of the nursing students to ethical values and their care behaviours. This study showed that the ethical values of the students positively affected their care behaviours. (shrink)

It has often been argued that if a clinician cannot decide which of two treatments to offer, a trial may be ethical, but it is unethical if she/he has a preference. Since individual clinicians usually have a preference, most trials could be judged unethical according to this line of argument. A recent important article in the New England Journal of Medicine argued that individual preferences are not as important as the collective uncertainty of informed clinicians. If clinicians are equally divided, (...) there is a state of collective equipoise and a trial is ethical. However, clinicians will seldom be exactly equally divided. We conducted an ethometric study to find out how much collective equipoise can be disturbed before the potential subjects in a trial think that it is unethical. Half of our subjects perceived a trial as unethical when equipoise was disturbed beyond 70:30. In other words, when 70 per cent of experts favour one treatment, 50 per cent of subjects would prefer that treatment to be administered rather than subjected to critical assessment. When equipoise is disturbed beyond 80:20, less than 3 per cent of subjects would consider human trials morally justifiable. (shrink)

BackgroundEuthanasia is performed on occasion, even on newborns, but is highly controversial, and it is prohibited by law and condemned by medical ethics in most countries.AimTo characterise and compare the judgments of lay persons, nurses, and physicians of the acceptability of actively ending the life of a damaged newborn.MethodsConvenience samples of 237 lay persons, 214 nurses, and 76 physicians in the south of France rated the acceptability on a scale of 0–10 of giving a lethal injection in 54 scenarios composed (...) of all combinations of 4 within-subject factors: gestational age of 6,7, or 9 months; 3 levels of severity of either perinatal asphyxia or of genetic disease; attitude of the parents about prolonging care unknown, favourable, or unfavourable; and decision made individually by the physician or collectively by the medical team. Overall ratings were subjected to cluster analysis and each cluster to analysis of variance and graphic representation.ResultsLay persons (mean acceptability rating 4.29) were significantly more favourable to euthanasia than nurses (2.84), p<.005, or physicians (2.12), p<.005. Five clusters were found with different judgment rules, i.e., how the information was integrated. More physicians (30 per cent) than nurses (14 per cent), p<.01, or lay persons (11 percent), p<.01, rated euthanasia as never, under any condition, acceptable. Most, however, asserted that it was increasingly acceptable as the factors combined to favour it, especially when the parents desired to stop treatment. More physicians (45 per cent) and nurses (46 per cent) than lay persons (21 per cent), p<.01, used a complex conjunctive rule (level of parent’s attitude x level of severity of damage x consultation with team or not) rather than a simple additive rule.ConclusionsUnlike lawand medical ethics, most of the lay persons. nurses, and physicians judged the acceptability of euthanasia as a function of the circumstances. Most health professionals combined the factors in a conjunctive (multiplicative), rather than additive, fashion in accordance with legislation for adults in the Netherlands and elsewhere that requires a set of criteria to be fulfilled before it is legitimate to end apatient’s life.

As part of an ethics course, health professions students were asked to identify ethical issues and to propose resolutions before and after a class discussion of a case involving confidentiality and substance abuse. Students listed an average of 2.4 issues before and 3.6 issues after the discussion. After discussion 50 per cent of students made explicit changes in their proposed resolution. Opinions varied widely on breaching confidentiality and the responsibility for protecting the patient's health. After the discussion almost 20 per (...) cent of the class felt it was acceptable to breach confidentiality as long as the patient was unaware. Many students identified more with the health care provider than with the patient. The presence of substance abuse altered many students' views on confidentiality. In this experience students were less rigorous in their application of principles, creating an excellent opportunity for teaching through exploration of the complexity of ethical decision-making in a specific case.

From a position as one of the leading professional services firms in the world, with 85,000 staff in 84 countries and revenues in excess of $9 billion, Andersen effectively ceased to exist within a matter of months. Although Andersen’s conviction related specifically to a charge of obstructing justice, public attention focused on the audit relationship between (...) class='Hi'>Andersen and its major client, Enron Corporation, particularly the actions (and inactions) that had allowed Enron to post spectacular year-on-year earnings and profit growth.
