Many theories of complex cognitive-motor skill learning are built on the notion that basic cognitive processes group actions into easy-to-perform sequences. The present work examines predictions derived from laboratory-based studies of motor chunking and motor preparation using data collected from the real-time strategy video game StarCraft 2. We examined 996,163 action sequences in the telemetry data of 3,317 players across seven levels of skill. As predicted, the latency to the first action is delayed relative to the other actions in the (...) group. Other predictions, inspired by the memory drum theory of Henry and Rogers, received only weak support. (shrink)

This paper scrutinises the tenability of a strict conceptual distinction between space and matter via the lens of the debate between modified gravity and dark matter. In particular, we consider Berezhiani and Khoury's novel 'superfluid dark matter theory' as a case study. Two families of criteria for being matter and being spacetime, respectively, are extracted from the literature. Evaluation of the new scalar field postulated by SFDM according to these criteria reveals that it is as much matter as anything could (...) possibly be, but alsoꟷbelow the critical temperature for superfluidityꟷas much spacetime as anything could possibly be. A sequel paper examines possible interpretations of SFDM in light of this result, as well as the consequences for our understanding of the modified gravity/ dark matter distinction and the broader spacetime–matter distinction.

Two approaches have emerged to resolve discrepancies between predictions and observations at galactic and cosmological scales: introducing dark matter or modifying the laws of gravity. Practitioners of each approach claim to better satisfy a different explanatory ideal, either unification or simplicity. In this chapter, we take a closer look at the ideals and at the successes of these approaches in achieving them. Not only are these ideals less divisive than assumed, but moreover we argue that the approaches are focusing on (...) different aspects of the same ideal. This realisation opens up the possibility of a more fruitful trading zone between dark matter and modified gravity communities. (shrink)

According to the standard model of cosmology, Λ\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\Lambda $$\end{document}CDM, the mass-energy budget of the current stage of the universe is not dominated by the luminous matter that we are familiar with, but instead by some form of dark matter (and dark energy). It is thus tempting to adopt scientific realism about dark matter. However, there are barely any constraints on the myriad of possible properties of this entity—it is not even certain (...) that it is a form of matter. In light of this underdetermination I advocate caution: we should not (yet) be dark matter realists. The “not(-yet)-realism” that I have in mind is different from Hacking’s (Philos Sci 56 (4), 555–581, 1989) anti-realism, in that it is semantic rather than epistemological. It also differs from the semantic anti-realism of logical empiricism, in that it is naturalistic, such that it may only be temporary and does not automatically apply to all other unobservables (or even just to all other astronomical unobservables, as with Hacking’s anti-realism). The argument is illustrated with the analogy of the much longer history of the concept of a gene, as the current state of the concept of dark matter resembles in some relevant ways that of the early concept of genes.

Tuberculosis (TB) is a potentially fatal infectious disease that, in Aotearoa New Zealand (NZ), inequitably affects Asian, Pacific, Middle Eastern, Latin American, and African (MELAA), and Māori people. Medical research involving genome sequencing of TB samples enables more nuanced understanding of disease strains and their transmission. This could inform highly specific health interventions. However, the collection and management of TB isolate samples for research are currently informed by monocultural biomedical models often lacking key ethical considerations. Drawing on a qualitative kaupapa (...) Māori–consistent study, this paper reports on preliminary discussions with groups of Māori, Pacific, and Afghan people in NZ, whose communities have been harmed by TB and TB stigma. Participants’ discussions highlight key concerns and meanings that ought to inform the development of guidelines and a more robust consultative process for the governance of how TB isolate samples are collected and used both retrospectively and in future research. We argue for ethical processes to be culturally nuanced and community-generated, flexible and meaningful, and situated in relation to the physical and symbolic effects of TB. We discuss the significance of Indigenous data sovereignty, rights, and kāwanatanga (governorship) in shaping a multicultural data sovereignty model. (shrink)

This research explores the contextual approach within Christian-Jewish religious education, addressing a notable gap in existing literature and offering fresh insights into the application of the Contextual Teaching and Learning (CTL) model within Christian contexts. Through a qualitative literature study employing a three-step methodology, including an in-depth analysis of Deuteronomy 11:19–20, this study reveals that this biblical text provides both educational guidance and theological significance, serving as a foundational support for the CTL model in Christian-Jewish religious education. The integration of (...) digital media into biblical sources holds promise for future research, while the central challenge lies in harmonising life experiences and empirical phenomena with biblical reflections to seamlessly integrate inquiry processes and pedagogical phases, with potential avenues for further exploration in scripture models endorsing CTL. This research provides valuable insights for educators, parents and policymakers in Indonesia and beyond, advancing educational research in contextualised teaching models within religious education.Contribution: This article demonstrates that the CTL model in the digital era has the potential to revolutionise religious education and profoundly impact learners, making it a significant scientific contribution in the context of Christian-Jewish religious education.

Most liberals agree that governments should protect certain basic liberties, such as freedom of speech, freedom of religion and freedom of the person. Liberals disagree, however, about whether free market rights should also be protected. By “free market rights,” we mean those rights typically associated with laissez-faire economic systems such as freedom of contract, a right to market returns, and claims to privately own the means of production.We do not use the phrase “economic liberties,” as Tomasi does, because it does (...) not distinguish between the “economic rights” defended by classical liberal and those defended by socialists. Those on the right often see such freedoms as core liberal commitments, while those on the left argue that an economic system should be organized to protect the interests of the less advantaged members of society. If free market rights should be protected, then most existing societies are unjust. These societies fail the liberal standard in the same ways as th .. (shrink)

To be a conventionalist about a specific obligation or right is to believe that the obligation or right is dependent on the existence of a social practice. A conventionalist about property, for example, believes that a moral right to property is generated by conventional norms rather than by any natural right. One problem with dominant conventionalist theories is that they do not adequately justify conventional moral claims. They can justify why it is wrong to steal, for example, but they do (...) not justify the claim that you have on me to not steal from you. As a remedy, this article develops and defends the Principle of Legitimate Expectations. Suggested by John Rawls, this principle grants individuals a moral claim to what the rules of morally justified practices entitle them. This article addresses common objections to the principle to show how it can ground a wide range of conventional moral claims. (shrink)

This article challenges a reductive analysis of social practices by distinguishing five kinds of reason for following the rules of conventional practices. Depending on one’s preferred intellectual tradition, conventional practices enable coordination, facilitate cooperation, constitute activities, fulfil reciprocity, or specify abstract rights. Instead of being rival theories of social practices, these different models complement one another in a normative analysis of social practices. By distinguishing five kinds of reasons to follow conventional rules, this paper supports a more dynamic conventionalist analysis (...) of subjects like property, the law, professional obligation, civic responsibility, and culture.

In The Tyranny of the Ideal, Gerald Gaus gives an extended argument on behalf of the “Open Society.” Instead of claiming that it is uniquely best from some privileged moral perspective, he argues for the Open Society by showing why it is acceptable to many perspectives. In this way, Gaus argues for a liberal market-based society in a way that treats deep diversity as a fundamental feature of social life. However, the argument falters at four important points. When taken together, (...) these four problems significantly limit the significance of Gaus’s conclusions. (shrink)

It has recently been argued that hope is polysemous in that it sometimes refers to hoping and other times to being hopeful. That it has these two distinct senses is reflected in the observation that a person can hope for an outcome without being hopeful that it will occur. Below, I offer a new argument for this distinction. My strategy is to show that accepting this distinction yields a rich account of two distinct ways in which hope can be lost, (...) ways that map onto the two senses of hope: A person can lose hope either by ceasing to hope for an outcome (hopelessness) or by ceasing to be hopeful that it will obtain (despair). Thinking about these negative attitudes in these two ways, I contend, is explanatorily rich and fruitfully reveals how they differ in phenomenology, behavioral differences, and the ways in which a person can escape them.

In their simplest form, hybrid languages are propositional modal languages which can refer to states. They were introduced by Arthur Prior, the inventor of tense logic, and played an important role in his work: because they make reference to specific times possible, they remove the most serious obstacle to developing modal approaches to temporal representation and reasoning. However very little is known about the computational complexity of hybrid temporal logics.In this paper we analyze the complexity of the satisfiability problem of (...) a number of hybrid temporal logics: the basic hybrid language over transitive trees; nominal Until logic; and referential interval logic. We discuss the effects of including nominals, the @ operator, the somewhere modality E, and the difference operator D. Adding nominals to tense logic leads for several frame-classes to an increase in complexity of the satisfiability problem from PSPACE to EXPTIME. On transitive trees, however, the satisfiability problem for this language can be decided in PSPACE. Along the way we make a detour through hybrid propositional dynamic logic: we establish upper bounds for a number of temporal logics by generalizing results due to Passy and Tinchev [29] and De Giacomo [16]. We conclude with some remarks on the relevance of our results to description logic, and draw attention to the utility of the spypoint technique for proving upper and lower bounds. (shrink)

This reply to an ongoing debate between conspiracy theory researchers from different disciplines exposes the conceptual confusions that underlie some of the disagreements in conspiracy theory research. Reconciling these conceptual confusions is important because conspiracy theories are a multidisciplinary topic and a profound understanding of them requires integrative insights from different fields. Specifically, we distinguish research focussing on conspiracy *theories* (and theorizing) from research of conspiracy *belief* (and mindset, theorists) and explain how particularism with regards to conspiracy theories does not (...) mean we cannot define a problematic subclass of conspiracy beliefs, while avoiding the problems of generalism. We hope this reply helps conspiracy theory researchers recognize the differences between studying conspiracy theories and conspiracy beliefs and appreciate the possibilities for fruitful, integrative, and interdisciplinary research.

Atheism Considered is a systematic presentation of challenges to the existence of a higher power. Rather than engage in polemic against a religious worldview, C.M. Lorkowski charitably refutes the classical arguments for the existence of god, pointing out flaws in their underlying reasoning and highlighting difficulties inherent to revealed sources. In place of a theistic worldview, he argues for adopting a naturalistic one, highlighting naturalism’s capacity to explain world phenomena and contribute to the sciences. Lorkowski demonstrates that replacing theism with (...) naturalism, contra popular assumptions, sacrifices nothing in terms of ethics or meaning. Instead, morality ultimately proves more important than religion and does not rely on it. Appropriate for classroom use, this book is meant to cultivate understanding, tolerance, and fruitful dialogue between believers and nonbelievers. (shrink)

The metre of Olympian II is still a matter of some difficulty. It has commonly been recognized as differing from Pindar's other metres, but many opinions have been held of its character. An understanding of it is, however, not merely essential to any general theory of Pindar's metric but vital to the textual criticism of the poem. Without some coherent theory we cannot say where ‘Responsionsfreiheiten’ are allowed and some important cruces remain unsolved. In recent years three theories have been (...) put forward. In his Res Metrica pp. 153–5 W. R. Hardie put forward the view that it is an example of a μέτρον μονοεɩδές composed in Cretic verse. He holds that it is written in Cretics or their recognized metrical equivalent, Paeons. This kind of verse is known from the Delphic Paean to Apollo and the Paean of Limenius, and so far as the equivalence of Cretics and Paeons is concerned, there is no difficulty in it. But as Hardie himself admitted, his theory does not account for all the facts. It may be said to suffer from the following defects. n In Str. 1, 3, 5, 7 and Ep. 1, 4, 5 he has to assume the existence of an extra single syllable at the beginning of the line. Since all attempts to defend ‘Anacrusis’ are extremely doubtful, this can hardly be maintained here. 2. The clausula of the Strophe cannot be reduced to Cretics or Paeons. 3. He has to admit that in Ep. 2 and 3 there is ‘some Trochaic movement’ and presumably he would have to admit that in Str. 3 there is either an Iambic, or, as he would prefer, a Trochaic movement with Anacrusis in ἤτοɩ πɩσα μεν. There is certainly some truth in Hardie's theory, but since it does not consider all the facts or co-ordinate them into a whole, it is not really satisfactory. (shrink)

In Strategic Justice, Peter Vanderschraaf introduces a “Baseline Consistency” criterion for Justice as Mutual Advantage. This criterion requires assessing how well individuals fare under existing conventions with how well they would fare under hypothetical social conditions. However, this comparison requires the impossible. Under different social conditions, individuals would have different preferences and different interests. As such, we cannot make any direct comparison between how well an individual fares across the two social conditions. The standard of assessment would change from one (...) context to the other. In order to apply the Baseline Consistency criterion, Vanderschraaf would need to justify an interpersonally valid standard for individual welfare, but this is incompatible with his Neo-Hobbesian method. If he abandoned the Baseline Consistency criterion, however, Vanderschraaf faces the “too many equilibria” problem. Conventions that are clearly objectionable would be considered just. (shrink)

Background Inadequate knowledge among health care providers (HCPs) and parents of affected children limits the understanding and utility of secondary genetic findings (SFs) in under-represented populations in genomics research. SFs arise from deep DNA sequencing done for research or diagnostic purposes and may burden patients and their families despite their potential health importance. This study aims to evaluate the perspective of both groups regarding SFs and their choices in the return of results from genetic testing in the context of orofacial (...) clefts.Methods Using an online survey, we evaluated the experiences of 252 HCPs and 197 parents across participating cleft clinics in Ghana and Nigeria toward the return of SFs across several domains.Results Only 1.6% of the HCPs felt they had an expert understanding of when and how to incorporate genomic medicine into practice, while 50.0% agreed that all SFs should be returned to patients. About 95.4% of parents were willing to receive all the information from genetic testing (including SFs), while the majority cited physicians as their primary information source (64%).Conclusions Overall, parents and providers were aware that genetic testing could help in the clinical management of diseases. However, they cited a lack of knowledge about genomic medicine, uncertain clinical utility, and lack of available learning resources as barriers. The knowledge gained from this study will assist with developing guidelines and policies to guide providers on the return of SFs in sub-Saharan Africa and across the continent. (shrink)

A common adage runs that, given a theory manifesting symmetries, the syntax of that theory should be modified in order to construct a new theory, from which symmetry-variant structure of the original theory has been excised. Call this strategy for explicating the underlying ontology of symmetry-related models reduction. Recently, Dewar has proposed an alternative to reduction as a means of articulating the ontology of symmetry-related models—what he calls sophistication, in which the semantics of the original theory is modified, and symmetry-related (...) models of that theory are treated as if they are isomorphic. In this paper, we undertake a critical evaluation of sophistication about symmetries—we find the programme underdeveloped in a number of regards. In addition, we clarify the interplay between sophistication about symmetries, and a separate debate to which Dewar has contributed—viz., that between interpretational versus motivational approaches to symmetry transformations.

The idea that society is a cooperative venture has been used by contractualists, contractarians, and deliberative democrats to justify the burdens of society to each member. In such a cooperative venture, those who benefit from society owe a contribution and those who contribute are owed benefits. Even though this idea is quite intuitive, there are deep disagreements about what makes society cooperative. Some focus on acts of production, others on fair interaction, and still others on the intention to contribute to (...) shared projects. In this article, I show where this kind of disagreement causes problems in current debates, and I defend one conception of social cooperation as uniquely best. Specifically, I argue that the relevant acts that make society a cooperative venture are acts of institutional rule-following. Society is a cooperative venture because people cooperate with one another by following the rules of our basic institutions. (shrink)

Conscious macrostates are usually assumed to be emergent from the underlying physical microstates comprising the brain and nervous system of biological organisms. However, a major problem with this assumption is that consciousness is essentially nonmeasurable unlike all other proven emergent properties of physical systems. In an earlier paper, using a no-go theorem, it was shown that conscious states cannot be comprised of processes that are physical in nature (Reason, 2019). Combining this result with another unrelated work on causal emergence in (...) physical systems (Hoel, Albantakis and Tononi, 2013), we show in this paper that conscious macrostates are not emergent from physical systems and they also do not supervene on physical microstates. An important implication of our work is that there must be some form of violation of energy conservation in biological systems that are conscious. (shrink)
