ABSTRACT. Statements not only update our current knowledge, but also have other dynamic effects. In particular, suggestions or commands ‘upgrade ’ our preferences by changing the current order among worlds. We present a complete logic of knowledge update plus preference upgrade that works with dynamic-epistemic-style reduction axioms. This system can model changing obligations, conflicting commands, or ‘regret’. We then show how to derive reduction axioms from arbitrary definable relation changes. This style of analysis also has a product update version with preferences between actions, as well as worlds. Some illustrations are presented involving defaults and obligations. We conclude that our dynamic framework is viable, while admitting a further extension to more numerical ‘utility update’.

Deep brain stimulation (DBS) has become a widespread and valuable treatment for patients with movement disorders such as essential tremor (ET). However, current DBS treatment constantly delivers stimulation in an open loop, which can be inefficient. Closing the loop with sensors to provide feedback may increase power efficiency and reduce side effects for patients. New implantable neuromodulation platforms, such as the Medtronic Activa PC+S DBS system, offer important data sources by providing chronic neural sensing capabilities and a means of investigating dynamic stimulation based on symptom measurements. The authors implanted in a single patient with ET an Activa PC+S system, a cortical strip of electrodes on the hand sensorimotor cortex, and therapeutic electrodes in the ventral intermediate nucleus of the thalamus. In this paper they describe the effectiveness of the platform when sensing cortical movement intentions while the patient actually performed and imagined performing movements. Additionally, they demonstrate dynamic closed-loop DBS based on several wearable sensor measurements of tremor intensity.

Abstract In this article, we analyse social interactions, drawing on diverse points of views, ranging from dialectics, second-person neuroscience and enactivism to dynamical systems, active inference and machine learning. To this end, we define interpersonal attunement as a set of multi-scale processes of building up and materializing social expectations—put simply, anticipating and interacting with others and ourselves. While cultivating and negotiating common ground, via communication and culture-building activities, are indispensable for the survival of the individual, the relevant multi-scale mechanisms have been largely considered in isolation. Here, collective psychophysiology, we argue, can lend itself to the fine-tuned analysis of social interactions, without neglecting the individual. On the other hand, an interpersonal mismatch of expectations can lead to a breakdown of communication and social isolation known to negatively affect mental health. In this regard, we review psychopathology in terms of interpersonal misattunement, conceptualizing psychiatric disorders as disorders of social interaction, to describe how individual mental health is inextricably linked to social interaction. By doing so, we foresee avenues for an inter-personalized psychiatry, which moves from a static spectrum of disorders to a dynamic relational space, focusing on how the multi-faceted processes of social interaction can help to promote mental health. This article is part of the theme issue ‘Concepts in interaction: social engagement and inner experiences’.

A common argument against explanatory reductionism is that higher-level explanations are sometimes or always preferable because they are more general than reductive explanations. Here I challenge two basic assumptions that are needed for that argument to succeed. It cannot be assumed that higher-level explanations are more general than their lower-level alternatives or that higher-level explanations are general in the right way to be explanatory. I suggest a novel form of pluralism regarding levels of explanation, according to which explanations at different levels are preferable in different circumstances because they offer different types of generality, which are appropriate in different circumstances of explanation.

OBJECTIVE: This study explores how surgeons define innovation, critically examines and evaluates these views, and uses the findings to develop practical criteria for identifying surgical innovation for ethical and regulatory purposes. BACKGROUND: Surgical innovation is crucial for progress in surgery, but can be harmful to patients and difficult to identify and therefore support appropriately. Current attempts to define surgical innovation lack precision, and do not give enough guidance to identify innovations in practice. This study is the first to give an account of surgeons' own views about defining innovation. METHODS: This qualitative study involved interviews with 18 Australian surgeons. Participants provided examples of innovation and distinguished innovation from variations in practice and from research. Data were collected using audio-recorded semistructured interviews. The data were coded using a template and analyzed to develop a thematic account of innovative surgery in practice. RESULTS: There was no uniform view about innovation, but participants identified 5 features of surgical innovation that distinguish it from variations: newness or novelty; degree of change; level of risk; impact; and requiring formal processes. There was no agreement on the distinction between innovation and research. CONCLUSIONS: Drawing on surgeons' own views is important for the development of a practical definition of surgical innovation. We have used a critical analysis of surgeons' own views as the basis for defining the core features of innovation. A precise definition of innovation will assist surgeons to identify and manage innovation and thereby enhance patient safety.

BACKGROUND: Large language models (LLMs) have gained prominence since the release of ChatGPT in late 2022. OBJECTIVE: The aim of this study was to assess the accuracy of citations and references generated by ChatGPT (GPT-3.5) in two distinct academic domains: the natural sciences and humanities. METHODS: Two researchers independently prompted ChatGPT to write an introduction section for a manuscript and include citations; they then evaluated the accuracy of the citations and Digital Object Identifiers (DOIs). Results were compared between the two disciplines. RESULTS: Ten topics were included, including 5 in the natural sciences and 5 in the humanities. A total of 102 citations were generated, with 55 in the natural sciences and 47 in the humanities. Among these, 40 citations (72.7%) in the natural sciences and 36 citations (76.6%) in the humanities were confirmed to exist (P=.42). There were significant disparities found in DOI presence in the natural sciences (39/55, 70.9%) and the humanities (18/47, 38.3%), along with significant differences in accuracy between the two disciplines (18/55, 32.7% vs 4/47, 8.5%). DOI hallucination was more prevalent in the humanities (42/55, 89.4%). The Levenshtein distance was significantly higher in the humanities than in the natural sciences, reflecting the lower DOI accuracy. CONCLUSIONS: ChatGPT's performance in generating citations and references varies across disciplines. Differences in DOI standards and disciplinary nuances contribute to performance variations. Researchers should consider the strengths and limitations of artificial intelligence writing tools with respect to citation accuracy. The use of domain-specific models may enhance accuracy.

Abstract Suppositional theories of conditionals take apparent similarities between supposition and conditionals as a starting point, appealing to features of the former to provide an account of the latter. This paper develops a novel form of suppositional theory, one which characterizes the relationship at the level of semantics rather than at the level of speech acts. In the course of doing so, it considers a range of novel data which shed additional light on how conditionals and supposition interact.

The concept of a ‘displaced academic’, which previously appeared in the analysis of the WWII-related forced migration from the Nazi-occupied Europe, has resurfaced in Ukraine’s higher education after Russia’s annexation of Crimea and invasion of the Donbas in 2014. We re-examine the relevance and interpretations of this concept in embattled Ukraine. Having interviewed 12 academics who fled the invaded territory, we seek to advance the theory of academic vulnerability in the context of geopolitical and cross-cultural divergences in the discordant post-Soviet space. Distinguished by its contextual analysis, this paper also expands the reader’s understanding of forced migration in a disintegrating higher education space.

There has been a lot of recent interest in the way that language might enhance embodied cognition. This interest is driven in large part by a growing body of evidence implicating the language system in various aspects of semantic memory-including, but not limited to, its apparent contribution to abstract concepts. In this essay, I develop and defend a novel account of the cognitive role played by language in our concepts. This account relies on the embodied nature of the language system itself, diverges in significant ways from traditional accounts, and is part of a flexible, multimodal and multilevel view of our conceptual system. This article is part of the theme issue 'Concepts in interaction: social engagement and inner experiences'.

In this piece, I discuss some aspects of the tension between democracy and constitutionalism in light of Pettit’s attempt to think popular control of government by way of a mixed constitution and the introduction of an alternative concept of representation.

Parallel to psychiatry, "philosophy of mind" investigates the relationship between mind (mental domain) and body/brain (physical domain). Unlike older forms of philosophy of mind, contemporary analytical philosophy is not exclusively based on introspection and conceptual analysis, but also draws upon the empirical methods and findings of the sciences. This article outlines the conceptual framework of the "mind-body problem" as formulated in contemporary analytical philosophy and argues that this philosophical debate has potentially far-reaching implications for psychiatry as a clinical-scientific discipline, especially for its own autonomy and its relationship to neurology/neuroscience. This point is illustrated by a conceptual analysis of the five principles formulated in Kandel's 1998 article "A New Intellectual Framework for Psychiatry." Kandel's position in the philosophical mind-body debate is ambiguous, ranging from reductive physicalism (psychophysical identity theory) to non-reductive physicalism (in which the mental "supervenes" on the physical) to epiphenomenalist dualism or even emergent dualism. We illustrate how these diverging interpretations result in radically different views on the identity of psychiatry and its relationship with the rapidly expanding domain of neurology/neuroscience.

The effects of the cation distribution change on the superexchange parameters and magnetic properties of cobalt ferrite powders were investigated. The cation distribution change of cobalt ferrite powders with quenching treatment was confirmed from the Mossbauer experiments. The exchange interaction parameters, i.e. J/sub AA/, J/sub BB/ and J(AB), and Neel temperature of slow-cooled and quenched CoFe/sub 2/O/sub 4/ powders were calculated from the variation of the magnetization with temperature on the basis of the two-sublattice model. With a quenching treatment of CoFe/sub 2/O/sub 4/, the thermal magnetization was changed, and this was attributed to the cation distribution change of cobalt ferrites. The absolute values of J/sub AB/ increased with the quenching treatment of CoFe/sub 2/O/sub 4/, while those of J/sub AA/ and T/sub N/ decreased. The values of J/sub BB/ of cobalt ferrite remained the same with the quenching treatment. This result suggested that the decrease of T/sub N/ of CoFe/sub 2/O/sub 4/ with quenching may be attributed to the decrease of J/sub AA/.

This article provides a theory of causation in the causal modeling framework. In contrast to most of its predecessors, this theory is model-invariant in the following sense: if the theory says that C caused (didn’t cause) E in a causal model, M, then it will continue to say that that C caused (didn’t cause) E once one has removed an inessential variable from M. The article suggests that, if this theory is true, then one should understand a cause as something which transmits deviant or noninertial behavior to its effect.

The recent debut and success of ChatGPT have brought up renewed debates and desires for artificial general intelligence (AGI) amid fears and anxieties of potential disruptions to our humanity and social values, as witnessed by the call from tech celebrities for a pause in the development of ChatGPT-style AGI tools. At the IEEE IS’ AI and CPSS Department, we would like to initiate cautious, balanced, hopefully deep investigations to address various related issues on the impact and significance of intelligent science and technology to our economy and society. Let’s start with the “three Bs” and “ACP” for parallel intelligence in CPSSs: Being by artificial systems (A), Becoming through computational experiments (C), and Believing with parallel execution (P).

BACKGROUND: Skin exposure to ultraviolet (UV) B radiation leads to epidermal damage and generation of reactive oxygen species. The photoprotective effect of extracts of three varieties of leaves (red, yellow, and black) from maca (Lepidium meyenii), a plant from the Peruvian highlands, was assessed in mouse skin exposed to UVB radiation. MATERIALS AND METHODS: The hydroalcoholic extracts of three varieties of maca leaves were applied topically to the dorsal skin of young-adult male mice prior to exposition to UVB radiation. RESULTS: The three varieties had UVA/UVB absorptive properties and presented antioxidant activity, being highest with red maca, followed by black and yellow maca. The three varieties of maca leaves prevented the development of sunburn cells, epidermal hyperplasia, leukocytic infiltration, and other alterations produced by UVB radiation. Mice treated with black maca showed the highest superoxide dismutase levels, and mice treated with black and yellow maca showed higher catalase levels in skin, whereas red maca protected the skin and liver against significant increases in the lipid peroxidation activity observed in the unprotected animals. CONCLUSION: The presence of significant antioxidant activity and the inhibition of lipid peroxidation suggest that the observed protection could be partly attributable to this mechanism.

= 15 responses). Using an experiential framework and an inductive approach to thematic analysis, we generated the following themes: (a) interpersonal relationships as a site of struggle, (b) fear and worry in response to contextual factors, (c) the weight of basic needs and safety, (d) gender as experienced through self and others, (e) intersections of health and rumination, and (f) the occasional reprieve. Using a deductive approach, we also placed these data within the context of Bronfenbrenner's Person-Process-Context-Time model to provide a conceptual model for future research in this area. These ruminative experiences revealed significant adversities and challenges weighing on participants' minds that spanned many areas of life. These findings also highlight the nuanced nature of rumination for TGD individuals and areas that may be overlooked in current assessments of this construct.

Hybridity as a heuristic concept of the globalization and post-colonialism discourses is used for 1) understanding the logic of the modernization of the higher education of Ukraine (HEU), and 2) for making a meaningful diagnosis of those educational pathologies that restrain it. The educational pathologies are considered as the conditioned by post-coloniality and post-totalitarianism departure or deviation from the undertaking of the original missions of higher education (HE): “to educate, to train and to undertake research” (World Declaration on Higher Education for the Twenty-First Century: Vision and Action, 1998). Modernity as a philosophical concept and normative ideal that focus on increasing rational components in a human life is exploited for showing the ways of carrying out the missions of HE by adjusting particular patterns of rationality to the needs and wants of society. However, globalization puts modernity under challenges due to its bent toward de/or non-modern cultural practices. That’s why the logic of modernization in HEU acquires hybrid characteristics by fitting together different, multiple, opposing educational models and standards – post-colonial, post-totalitarian, modern, de/non-modern and global through the local acceptance. Therefore, the locality turns into a focal point of the modernization of HEU in a global context. The modernization of HEU reveals the ambivalent meaning of hybridity in its producing and destructive potential, i.e. as a global logic or a local idiosyncrasy.

Research on concepts has focused on categorization. Categorization starts with a stimulus. Equally important are episodes that start with a thought. We engage in thinking to draw out new consequences from stored information, or to work out how to act. Each of the concepts out of which thought is constructed provides access to a large body of stored information. Access is not always just a matter of retrieving a stored belief (semantic memory). Often it depends on running a simulation. Simulation allows conceptual thought to draw on information in special-purpose systems, information stored in special-purpose computational dispositions and special-purpose representational structures. While the utility of simulation, prospection or imagination is widely appreciated, the role of concepts in the process is not well understood. This paper turns to cognitive and computational neuroscience for a model of how simulations enable thinkers to reach novel conclusions. Carried over to conceptual thought, the model suggests that concepts are 'plug & play' devices. The distinctive power of thought-driven simulation derives from the ability of concepts to plug into two kinds of structure at once: the combinatorial structure of a thought at one end and special-purpose structural representations at the other.
