The visual system adapts to a wide range of visual features, from lower-level features like color and motion to higher-level features like causality and, perhaps, number. According to some, adaptation is a strictly perceptual phenomenon, such that the presence of adaptation licenses the claim that a feature is truly perceptual in nature. Given the theoretical importance of claims about adaptation, then, it is important to understand exactly when the visual system does and does not exhibit adaptation. Here, we take as (...) a case study one specific kind of adaptation: visual adaptation to size. Supported by evidence from four experiments, we argue that, despite robust effects of size adaptation in the lab, (1) size adaptation effects are phenomenologically underwhelming (in some cases, hardly appreciable at all), (2) some effects of size adaptation appear contradictory, and difficult to explain given current theories of size adaptation, and (3) prior studies on size adaptation may have failed to isolate size as the adapted dimension. Ultimately, we argue that while there is evidence to license the claim that size adaptation is genuine, size adaptation is a puzzling and poorly understood phenomenon. (shrink)

We investigate a recently devised polyhedral semantics for intermediate logics, in which formulas are interpreted in n-dimensional polyhedra. An intermediate logic is polyhedrally complete if it is complete with respect to some class of polyhedra. The first main result of this paper is a necessary and sufficient condition for the polyhedral completeness of a logic. This condition, which we call the Nerve Criterion, is expressed in terms of Alexandrov’s notion of the nerve of a poset. It affords a purely combinatorial (...) characterisation of polyhedrally complete logics. Using the Nerve Criterion we show, easily, that there are continuum many intermediate logics that are not polyhedrally complete but which have the finite model property. We also provide, at considerable combinatorial labour, a countably infinite class of logics axiomatised by the Jankov–Fine formulas of ‘starlike trees’ all of which are polyhedrally complete. The polyhedral completeness theorem for these ‘starlike logics’ is the second main result of this paper. (shrink)

Cheating in the undergraduate classroom is not a new problem, and it is recognized as one that is endemic to the education system. This paper examines the highly normative behavior of using unauthorized assistance (e.g., a solutions manual or a friend) on an individual assignment within the context of an upper division undergraduate course in engineering mechanics. The findings indicate that there are varying levels of accepting responsibility among the students (from denial to tempered to full) and that acceptance of (...) responsibility can lead to identification of learning and necessary behavioral changes. The findings have implications for institutions and engineering faculty, in particular the need for consistent academic integrity education and the teaching of professional integrity and ethics.

Active at the time when the social sciences were founded, Max Weber's social theory contributed significantly to a wide range of fields and disciplines. Considering his prominence, it makes sense to take stock of the Weberian heritage and to explore the ways in which Weber's work and ideas have contributed to our understanding of the modern world. Using his work as a point of departure, The Oxford Handbook of Max Weber investigates the Weberian legacy today, identifying the enduring problems and (...) themes associated with his thought that have contemporary significance: the nature of modern capitalism, neo-liberal global economic policy, nationalism, religion and secularization, threats to legality, the culture of modernity, bureaucratic rule and leadership, politics and ethics, the value of science, power and inequality. These problems are global in scope, and the Weberian approach has been used to address them in very different societies. Thus, the Handbook also features chapters on Europe, Turkey, Islam, Judaism, China, India, and international politics. The Handbook emphasizes the use and application of Weber's ideas. It offers a journey through the intellectual terrain that scholars continue to explore using the tools and perspectives of Weberian analysis. The essays explore how Weber's concepts, hypotheses, and perspectives have been applied in practice, and how they can be applied in the future in social inquiry, not only in Europe and North America, but globally. The volume is divided into six parts exploring, in turn: Capitalism in a Globalized World, Society and Social Structure, Politics and the State, Religion, Culture, and Science and Knowledge.

The COVID-19 Law Lab platform enables quantitative representation of epidemic law and policies in a given country for multiple years, enabling governments and researchers to compare countries, and learn about the impacts and drivers of policy choices. The Law Lab initiative is designed to address the urgent need for quality legal information to support the study of how law and policy can be used to effectively manage this, and future, pandemic(s).

This paper, co-authored by undergraduate students and their instructor part of an educational psychology seminar, describes a participatory curriculum design approach for preservice teacher education that focuses on the use of the principles of second-order cybernetics to teach about teaching and learning. Using elements of an Open Source Educational Processes framework, our Spring ESEPSY2309 section created project-based collective hive minds of preservice teachers, relying on a cybernetic approach at the crossroads of Gregory Bateson and Gordon Pask's theories. The classroom community (...) used four innovative tool-mediated pillars to guide collaborative activity: 1) Live-chatting using the Reddit social media platform, 2) observation of the lives, strategies, and practices used by teachers and students in their own social networks through Soundcloud podcasting to expand their own perceptions of pedagogies and best practices that they could employ in their careers, 3) open-ended paper writing, exploring sources beyond the object language provided by the textbook through extensive dyadic conversations with the instructor, and 4) training in the use of the Alice 3 game creation tool for block programming enabling the accumulation of competence in designing classroom systems that may treat students these undergraduates would soon teach as active historical agents in learning environments, combining skills from varied subjects into transdisciplinary educational experiences. We showcase outcomes of our class projects using a narrative inquiry to describe podcast episodes, a topic network analysis to illustrate the expansive nature of Open Source writing activity, and a visual depiction of our class Alice 3 games.

Rationale: Deep brain stimulation (DBS) of the hippocampus is proposed for enhancement of memory impaired by injury or disease. Many pre-clinical DBS paradigms can be addressed in epilepsy patients undergoing intracranial monitoring for seizure localization, since they already have electrodes implanted in brain areas of interest. Even though epilepsy is usually not a memory disorder targeted by DBS, the studies can nevertheless model other memory-impacting disorders, such as Traumatic Brain Injury (TBI). Methods: Human patients undergoing Phase II invasive monitoring for (...) intractable epilepsy were implanted with depth electrodes capable of recording neurophysiological signals. Subjects performed a delayed-match-to-sample (DMS) memory task while hippocampal ensembles from CA1 and CA3 cell layers were recorded to estimate a multi-input, multi-output (MIMO) model of CA3-to-CA1 neural encoding and a memory decoding model (MDM) to decode memory information from CA3 and CA1 neuronal signals. After model estimation, subjects again performed the DMS task while either MIMO-based or MDM-based patterned stimulation was delivered to CA1 electrode sites during the encoding phase of the DMS trials. Each subject was sorted (post hoc) by prior experience of repeated and/or mild-to-moderate brain injury (RMBI), TBI, or no history (control) and scored for percentage successful delayed recognition (DR) recall on stimulated vs. non-stimulated DMS trials. The subject’s medical history was unknown to the experimenters until after individual subject memory retention results were scored. Results: When examined compared to control subjects, both TBI and RMBI subjects showed increased memory retention in response to both MIMO and MDM-based hippocampal stimulation. Furthermore, effects of stimulation were also greater in subjects who were evaluated as having pre-existing mild-to-moderate memory impairment. Conclusion: These results show that hippocampal stimulation for memory facilitation was more beneficial for subjects who had previously suffered a brain injury (other than epilepsy), compared to control (epilepsy) subjects who had not suffered a brain injury. This study demonstrates that the epilepsy/intracranial recording model can be extended to test the ability of DBS to restore memory function in subjects who previously suffered a brain injury other than epilepsy, and support further investigation into the beneficial effect of DBS in TBI patients.

Homeobox genes play essential roles in specifying the fates of different cell types during embryogenesis. In Drosophila, the homeotic gene caudal is important for the generation of posterior structures. In the mouse, the caudal homologue Cdx2 has been implicated in directing early processes in intestinal morphogenesis and in the maintenance of the differentiated phenotype. A recent study showed that Cdx2 null mutation was embryonically lethal, whereas Cdx2+/− mice developed multiple intestinal polyps in the proximal colon in addition to developmental defects(1). (...) There are striking phenotypic similarities and differences between Cdx2+/− and other mice predisposed to intestinal neoplasia. The possible role of Cdx2 in human colorectal tumorigenesis is discussed. (shrink)

According to the KK-principle, knowledge iterates freely. It has been argued, notably in Greco, that accounts of knowledge which involve essential appeal to normality are particularly conducive to defence of the KK-principle. The present article evaluates the prospects for employing normality in this role. First, it is argued that the defence of the KK-principle depends upon an implausible assumption about the logical principles governing iterated normality claims. Once this assumption is dropped, counter-instances to the principle can be expected to arise. (...) Second, it is argued that even if the assumption is maintained, there are other logical properties of normality which can be expected to lead to failures of KK. Such failures are noteworthy, since they do not depend on either a margins-for-error principle or safety condition of the kinds Williamson appeals to in motivating rejection KK. “Introduction: KK and Being in a Position to Know” Section formulates two versions of the KK-Principle; “Inexact Knowledge and Margins for Error” Section presents a version of Williamson’s margins-for-error argument against it; “Knowledge and Normality” and “Iterated Normality” Sections discuss the defence of the KK-Principle due to Greco and show that it is dependent upon the implausible assumption that the logic of normality ascriptions is at least as strong as K4; finally, “Knowledge in Abnormal Conditions” and “Higher-Order Ignorance Inside the Margins” Sections argue that a weakened version of Greco’s constraint on knowledge is plausible and demonstrate that this weakened constraint will, given uncontentious assumptions, systematically generate counter-instances to the KK-principle of a novel kind.

This paper develops an account of pluralities based on the following simple claim: some things are nothing over and above the individual things they comprise. For some, this may seem like a mysterious statement, perhaps even meaningless; for others, like a truism, trivial and inferentially inert. I show that neither reaction is correct: the claim is both tractable and has important consequences for a number of debates in philosophy.

Sam Harris dismantles the most common justification for religious faith--that a moral system cannot be based on science.

Elementary Recursive Nonstandard Analysis, in short ERNA, is a constructive system of nonstandard analysis with a PRA consistency proof, proposed around 1995 by Patrick Suppes and Richard Sommer. Recently, the author showed the consistency of ERNA with several transfer principles and proved results of nonstandard analysis in the resulting theories (see [12] and [13]). Here, we show that Weak König's lemma (WKL) and many of its equivalent formulations over RCA₀ from Reverse Mathematics (see [21] and [22]) can be 'pushed down' (...) into the weak theory ERNA, while preserving the equivalences, but at the price of replacing equality with equality 'up to infinitesimals'. It turns out that ERNA plays the role of RCA₀ and that transfer for universal formulas corresponds to WKL. (shrink)

According to a number of approaches in theoretical physics, spacetime does not exist fundamentally. Rather, spacetime exists by depending on another, more fundamental, non-spatiotemporal structure. A prevalent opinion in the literature is that this dependence should not be analyzed in terms of composition. We should not say, that is, that spacetime depends on an ontology of non-spatiotemporal entities in virtue of having them as parts. But is that really right? On the contrary, we argue that a mereological approach to dependent (...) spacetime is not only viable, but promises to enhance our understanding of the physical situation. (shrink)

The counterfactual approach to explainable AI (XAI) seeks to provide understanding of AI systems through the provision of counterfactual explanations. In a recent systematic review, Chou et al. (Inform Fus 81:59–83, 2022) argue that the counterfactual approach does not clearly provide causal understanding. They diagnose the problem in terms of the underlying framework within which the counterfactual approach has been developed. To date, the counterfactual approach has not been developed in concert with the approach for specifying causes developed by Pearl (...) (Causality: Models, reasoning, and inference. Cambridge University Press, 2000) and Woodward (Making things happen: A theory of causal explanation. Oxford University Press, 2003). In this paper, I build on Chou et al.’s work by applying the Pearl-Woodward approach. I argue that the standard counterfactual approach to XAI is capable of delivering causal understanding, but that there are limitations on its capacity to do so. I suggest a way to overcome these limitations. (shrink)

What should advocates of phenomenal intentionality say about unconscious intentional states? I approach this question by focusing on a recent debate between Tim Crane and David Pitt, about the nature of belief. Crane argues that beliefs are never conscious. Pitt, concerned that the phenomenal intentionality thesis coupled with a commitment to beliefs as essentially unconscious embroils Crane in positing unconscious phenomenology, counter-argues that beliefs are essentially conscious. I examine and rebut Crane’s arguments for the essential unconsciousness of beliefs, some of (...) which are widely endorsed. On the way I sketch a model of how belief states could participate in the stream of consciousness. I then consider Pitt’s position, arguing in reply, along Freudian lines, that we should posit not just dispositional but occurrent unconscious beliefs. This result, I argue, indeed requires advocates of phenomenal intentionality to posit unconscious qualia to fix these unconscious occurrent thoughts, and I defend the coherence of the notion of unconscious qualia against some common attacks. Ultimately, I claim, the combination of taking seriously the occurrent unconscious, and a commitment to phenomenal intentionality, should lead us to expand William James’s conception of the stream of consciousness to encompass, additionally, a stream of unconscious mental life—or, perhaps better, to posit a single partly conscious partly unconscious qualia-stream of mental goings-on.

A proposed empirical criterion for task susceptibility to introspective awareness distinguishes cognitive processes of which one cannot be aware from those of which one can be aware. The empirical criterion for task susceptibility to awareness effects proposes that there are tasks which cannot be affected by awareness of the rules constituting the tasks. These criteria were applied to research programmes in rule-learning in which past studies in the area of learning without awareness were included as well as current research in (...) implicit learning. The principal question addressed in these studies is whether or not rule-learning can occur without awareness. An historical review showed that rule-learning occurred in tasks which were both susceptible and insusceptible to introspective awareness and to awareness effects. Accordingly, it has been proposed that rather than attempt to decide theoretically and empirically between the opposing hypotheses—that of “cognitive learning” on the one hand, which assumes that awareness is a necessary condition for rule-learning, and that of “automatic learning” on the other, which assumes direct, automatic and unconscious processes—efforts should rather be directed toward developing a theoretical approach which is based on both conscious and unconscious processes. However, an approach of this kind encounters severe problems, such as the generation of contradictory predictions, which result from the employment of several incongruent and irreconcilable models of explanation. The criteria for task susceptibility offer a way out of these difficulties. (shrink)

Joint actions often require agents to track others’ actions while planning and executing physically incongruent actions of their own. Previous research has indicated that this can lead to visuomotor interference effects when it occurs outside of joint action. How is this avoided or overcome in joint actions? We hypothesized that when joint action partners represent their actions as interrelated components of a plan to bring about a joint action goal, each partner’s movements need not be represented in relation to distinct, (...) incongruent proximal goals. Instead they can be represented in relation to a single proximal goal – especially if the movements are, or appear to be, mechanically linked to a more distal joint action goal. To test this, we implemented a paradigm in which participants produced finger movements that were either congruent or incongruent with those of a virtual partner, and either with or without a joint action goal (the joint flipping of a switch, which turned on two light bulbs). Our findings provide partial support for the hypothesis that visuomotor interference effects can be reduced when two physically incongruent actions are represented as mechanically interdependent contributions to a joint action goal.

Our ordinary judgments and our metaphysical theories share a common commitment to facts about resemblance. The nature of resemblance is, however, a matter of no small controversy. This essay examines some of the pressing questions that arise regarding the status and structure of resemblance.

Is resemblance an objective or subjective matter? What, if any, resemblance (...) facts are fundamental? How does resemblance relate to naturalness? (shrink)

Reverse mathematics is a program in the foundations of mathematics founded by Friedman and developed extensively by Simpson and others. The aim of RM is to find the minimal axioms needed to prove a theorem of ordinary, that is, non-set-theoretic, mathematics. As suggested by the title, this paper deals with two RM-phenomena, namely, splittings and disjunctions. As to splittings, there are some examples in RM of theorems A, B, C such that A↔, that is, A can be split into two (...) independent parts B and C. As to disjunctions, there are examples in RM of theorems D, E, F such that D↔, that is, D can be written as the disjunction of two independent parts E and F. By contrast, we show in this paper that there is a plethora of splittings and disjunctions in Kohlenbach’s higher-order RM. (shrink)

In this paper, I will present and advocate a view about what we are doing when we attribute delusion, namely, say that someone is delusional. It is an “expressivist” view, roughly analogous to expressivism in meta-ethics. Just as meta-ethical expressivism accounts for certain key features of moral discourse, so does this expressivism account for certain key features of delusion attribution. And just as meta-ethical expressivism undermines factualism about moral properties, so does this expressivism, if correct, show that certain attempts to (...) objectively define delusion are misguided. I proceed as follows. I start by examining different attempts at defining delusion, separating broadly psychiatric attempts from epistemic ones. I then present a change of approach, according to which we question whether the term “delusion” is in the business of (merely) describing reality. I then support this proposal, first, by borrowing standard lines of argument from meta-ethics (including ontological reluctance, intrinsic motivation, and deep disagreement) but also, by inference to the best explanation of some the features we see when we try to theorise about delusion (namely that it is hard to define, and that our delusion attributions are elicited by a plurality of norms).

Artificial intelligence is not only disrupting industries and businesses, particularly the ones have fallen behind the adoption, but also significantly impacting public life as well. This calls for government authorities pay attention to public opinions and sentiments towards AI. Nonetheless, there is limited knowledge on what the drivers behind the public perception of AI are. Bridging this gap is the rationale of this paper. As the methodological approach, the study conducts an online public perception survey with the residents of Sydney, (...) Melbourne, and Brisbane, and explores the collected survey data through statistical analysis. The analysis reveals that: the public is concerned of AI invading their privacy, but not much concerned of AI becoming more intelligent than humans; the public trusts AI in their lifestyle, but the trust is lower for companies and government deploying AI; the public appreciates the benefits of AI in urban services and disaster management; depending on the local context, public perceptions vary; and the drivers behind the public perception include gender, age, AI knowledge, and AI experience. The findings inform authorities in developing policies to minimise public concerns and maximise AI awareness. (shrink)

The indispensability argument seeks to establish the existence of mathematical objects. The success of the indispensability argument turns on finding cases of genuine extra- mathematical explanation. In this paper, I identify a new case of extra- mathematical explanation, involving the search patterns of fully-aquatic marine predators. I go on to use this case to predict the prevalence of extra- mathematical explanation in science.

Is time necessary for causation? We argue that, given a counterfactual theory of causation, it is not. We defend this claim by considering cases of counterfactual dependence in quantum mechanics. These cases involve laws of nature that govern entanglement. These laws make possible the evaluation of causal counterfactuals between space-like separated entangled particles. There is, for the proponent of a counterfactual theory of causation, a possible world in which causation but not time exists that can be reached by ‘stripping out’ (...) time from the actual world, leaving quantum mechanical laws intact.

ABSTRACTPresentism and endurantism are natural bedfellows: arguments have been mounted from endurantism to presentism and vice versa. I generalise an argument against the compatibility between presentism and endurantism offered recently by Tallant. I then show how to reformulate endurantism so that it is compatible with presentism. I demonstrate that this reformulated version of endurantism can do the same work with respect to the problem of temporary intrinsics as can standard definitions.

Standard approaches to counterfactuals in the philosophy of explanation are geared toward causal explanation. We show how to extend the counterfactual theory of explanation to non-causal cases, involving extra-mathematical explanation: the explanation of physical facts by mathematical facts. Using a structural equation framework, we model impossible perturbations to mathematics and the resulting differences made to physical explananda in two important cases of extra-mathematical explanation. We address some objections to our approach.

Do properties have intrinsic properties of their own? If so, which second-order properties are intrinsic? This paper introduces two competing views about second-order intrinsicality: generalism, according to which the intrinsic–extrinsic distinction cuts across all orders of properties and applies to the properties of properties as well as the properties of objects, and objectualism, according to which intrinsicality is a feature exclusive to the properties of objects. The case for generalism is then surveyed along with some proposals for distinguishing intrinsic second-order (...) properties from extrinsic ones. After addressing these broad questions about the nature of second-order intrinsicality, the Problem of Accidental Intrinsic Properties of Properties is introduced and put to work as a case study for the significance of second-order intrinsicality. The connection between this problem and the metaphysics of quantitative properties is then examined. (shrink)

Non-local phonological patterns can be difficult to analyze in the context of speech production models. Some patterns – e.g., vowel harmonies, nasal harmonies – can be readily analyzed to arise from temporal extension of articulatory gestures (i.e., spreading); such patterns can be viewed as articulatorily local. However, there are other patterns – e.g., nasal consonant harmony, laryngeal feature harmony – which cannot be analyzed as spreading; instead these patterns appear to enforce agreement between features of similar segments without affecting intervening (...) segments. Indeed, there are numerous typological differences between spreading harmonies and agreement harmonies, and this suggests that there is a mechanistic difference in the ways that spreading and agreement harmonies arise. This paper argues that in order to properly understand spreading and agreement patterns, the gestural framework of Articulatory Phonology must be enriched with respect to how targets of the vocal tract are controlled in planning and production. Specifically, it is proposed that production models should distinguish between excitatory and inhibitory articulatory gestures, and that gestures which are below a selection threshold can influence the state of the vocal tract, despite not being active. These ideas are motivated by several empirical phenomena, which include anticipatory posturing before production of a word form, and dissimilatory interactions in distractor-target response paradigms. Based on these ideas, a model is developed which provides two distinct mechanisms for the emergence of non-local phonological patterns. (shrink)
