The mesostriatal dopamine system is prominently implicated in model-free reinforcement learning, with fMRI BOLD signals in ventral striatum notably covarying with model-free prediction errors. However, latent learning and devaluation studies show that behavior also shows hallmarks of model-based planning, and the interaction between model-based and model-free values, prediction errors, and preferences is underexplored. We designed a multistep decision task in which model-based and model-free influences on human choice behavior could be distinguished. By showing that choices reflected both influences we could (...) then test the purity of the ventral striatal BOLD signal as a model-free report. Contrary to expectations, the signal reflected both model-free and model-based predictions in proportions matching those that best explained choice behavior. These results challenge the notion of a separate model-free learner and suggest a more integrated computational architecture for high-level human decision-making. (shrink)

We discuss potential biorisks from large language models (LLMs). AI assistants based on LLMs such as ChatGPT have been shown to significantly reduce barriers to entry for actors wishing to synthesize dangerous, potentially novel pathogens and chemical weapons. The harms from deploying such bioagents could be further magnified by AI-assisted misinformation. We endorse several policy responses to these dangers, including prerelease evaluations of biomedical AIs by subject-matter experts, enhanced surveillance and lab screening procedures, restrictions on AI training data, and access (...) controls on biomedical AI. We conclude with a suggestion about future research directions in bioethics. (shrink)

Given its non-invasive nature, there is increasing interest in the use of transcutaneous vagus nerve stimulation across basic, translational and clinical research. Contemporaneously, tVNS can be achieved by stimulating either the auricular branch or the cervical bundle of the vagus nerve, referred to as transcutaneous auricular vagus nerve stimulation and transcutaneous cervical VNS, respectively. In order to advance the field in a systematic manner, studies using these technologies need to adequately report sufficient methodological detail to enable comparison of results between (...) studies, replication of studies, as well as enhancing study participant safety. We systematically reviewed the existing tVNS literature to evaluate current reporting practices. Based on this review, and consensus among participating authors, we propose a set of minimal reporting items to guide future tVNS studies. The suggested items address specific technical aspects of the device and stimulation parameters. We also cover general recommendations including inclusion and exclusion criteria for participants, outcome parameters and the detailed reporting of side effects. Furthermore, we review strategies used to identify the optimal stimulation parameters for a given research setting and summarize ongoing developments in animal research with potential implications for the application of tVNS in humans. Finally, we discuss the potential of tVNS in future research as well as the associated challenges across several disciplines in research and clinical practice. (shrink)

In Classical Quarterly N.S. ix , 80 ff. Professor Hugh Lloyd-Jones published an article on the closing scenes of Seven Against Thebes. In it he directed an assault on the orthodox belief that these scenes are, in whole or in part, not authentic. The movement in favour of authenticity seemed all the stronger when independently, and in the same year, Walter Potscher put forward arguments in Eranos in defence of some parts of the disputed passages.

Do philosophic views affect job performance? The authors found that possessing a belief in free will predicted better career attitudes and actual job performance. The effect of free will beliefs on job performance indicators were over and above well-established predictors such as conscientiousness, locus of control, and Protestant work ethic. In Study 1, stronger belief in free will corresponded to more positive attitudes about expected career success. In Study 2, job performance was evaluated objectively and independently by a supervisor. Results (...) indicated that employees who espoused free will beliefs were given better work performance evaluations than those who disbelieve in free will, presumably because belief in free will facilitates exerting control over one’s actions.

D’où vient la transparence et où va-t-elle? Quelles sont ses méthodes? Quels types de savoirs doivent être constitués pour nous la fournir? Cet article propose la description d’un tableau de bord informationnel, c’est-à-dire d’une interface de plus en plus souvent déployée dans les initiatives relevant de la transparence. Cet Index des Clés Performatives aide à percevoir l’emprise des régimes de mesure et de gestion de performance sur notre monde. Pour expliquer le parcours allant de la transparence à la gestion de (...) performance à travers les tableaux de bord, cet article revient sur un scandale récent de la politique britannique qui a déclenché une nouvelle poussée d’appels à la transparence, et finalement à la multiplication des tableaux de bords.

Humean promotionalists about reasons think that whether there is a reason for an agent to ϕ depends on whether her ϕ-ing promotes the satisfaction of at least one of her desires. Several authors have recently defended probabilistic accounts of promotion, according to which an agent’s ϕ-ing promotes the satisfaction of one of her desires just in case her ϕ-ing makes the satisfaction of that desire more probable relative to some baseline. In this paper I do three things. First, I formalize (...) an argument, due to Jeff Behrends and Joshua DiPaolo, to the effect that Mark Schroeder’s and Stephen Finlay’s probabilistic accounts of promotion cannot be correct. Next, I extend this argument to a recent alternative offered by D. Justin Coates and show how Coates’ attempt to avoid the argument by introducing a distinction between ‘intrinsic’ and ‘extrinsic’ probability doesn’t help. Finally, I suggest an alternative way of understanding promotion in terms of increase in degree of fit between the causal upshot of an action and the content of a desire. I show how this view, disjunctively paired with probabilism about promotion, solves the problems with previous accounts. (shrink)

This paper addresses and proposes to resolve a longstanding problem in the philosophy of physics: whether and in what sense Albert Einstein’s Chasing the Light thought experiment was significant in the development of the theory of special relativity. Although Einstein granted this thought experiment pride of place in his 1949 Autobiographical Notes, philosophers and physicists continue to debate about what, if anything, the experiment establishes. I claim that we ought to think of Chasing the Light as Einstein’s first attempt to (...) problematize the very idea of the electromagnetic ether frame, and that it thereby contributed to his eventual adoption of one of special relativity’s two foundational axioms: the “light postulate”. This interpretation requires the assumption that Einstein had presupposed special relativity’s other axiom, the “principle of relativity”, when initially considering Chasing the Light. This argument is novel insofar as it provides evidence that such a presupposition by Einstein is both conceptually and historically plausible. Moreover, this paper directly challenges John D. Norton’s compelling claim that Chasing the Light is best understood as a refutation of emission theories of light propagation; while both interpretations of the experiment are conceptually coherent, I argue that the interpretation found in this paper is supported more straightforwardly by historical evidence.

RésuméLa parution récente du troisième recueil d'articles de Donald Davidson, lequel devrait être suivi de deux autres, incite à examiner les thèmes qui traversent tousses travaux. Parmices thèmes se trouve leprincipe de charité. Considerant tout le parti que Davidson a tiré du PC, je me propose d'en faire un examen attentif. Dans la première partie, j'examine diverses formulations du PC par Davidson. Dans la seconde partie, je montre que la formulation qu'exigent ses travaux d'epistémologie est intenable étant donné ce qu'il (...) en dit dans ses travaux de sémantique. De là, je conclus que Davidson ne peut se servir du PC que dans ses travaux de sémantique ou pas du tout. (shrink)

Ce bref article propose un panorama des différentes approches théoriques et méthodologiques pour analyser le néolibéralisme. Il s’attache tout spécialement à définir les approches politico-économiques et gouvernementales (et dans quelle mesure elles s’opposent ou se combinent) et plaide en faveur d’une critique du néolibéralisme mieux construite sur le plan théorique et méthodologique dans le champ des Media Studies. En soulignant l’hétérogénéité des modes d’analyse d’un objet tel que le néolibéralisme, ainsi que les différences dans la manière dont ces approches se (...) déploient dans d’autres domaines des Studies, il préconisera donc d’appliquer ces regards critiques à la recherche menée également au sein de multiples disciplines dans d’autres pays (comme la France).

Push: Software Design and the Cultural Politics of Music Production shows how changes in the design of music software in the first decades of the twenty-first century shaped the production techniques and performance practices of artists working across media, from hip-hop and electronic dance music to video games and mobile apps. Emerging alongside developments in digital music distribution such as peer-to-peer file sharing and the MP3 format, digital audio workstations like FL Studio and Ableton Live introduced design affordances that encouraged (...) rapid music creation workflows through flashy, "user-friendly" interfaces. Meanwhile, software such as Avid's Pro Tools attempted to protect its status as the "industry standard," "professional" DAW of choice by incorporating design elements from pre-digital music technologies. Other software, like Cycling 74's Max, asserted its alterity to "commercial" DAWs by presenting users with nothing but a blank screen. These are more than just aesthetic design choices. Push examines the social, cultural, and political values designed into music software, and how those values become embodied by musical communities through production and performance. It reveals ties between the maximalist design of FL Studio, skeuomorphic design in Pro Tools, and gender inequity in the music products industry. It connects the computational thinking required by Max, as well as iZotope's innovations in artificial intelligence, with the cultural politics of Silicon Valley's "design thinking." Finally, it thinks through what happens when software becomes hardware, and users externalize their screens through the use of MIDI controllers, mobile media, and video game controllers. Amidst the perpetual upgrade culture of music technology, Push provides a model for understanding software as a microcosm for the increasing convergence of globalization, neoliberal capitalism, and techno-utopianism that has come to define our digital lives.

This essay provides an interpretation of Nathaniel Hawthorne's short story 'My Kinsman, Major Molineux.' It argues that in this story Hawthorne is presenting a tale of social transformation from the pre-modern to the modern society in the form of the protagonist Robin's experiences on coming from the backwoods to the city. Here Robin sees things he has never seen before and is transformed in terms of his religious attitudes as well as in terms of his simple individual,rural independence. Robin (...) ends up joining the urban mob in its humiliation of the gentleman figure of Major Molineux. The new urban world of the 19th Century is sympathetic neither to rural simplicty nor to gentlemanly dignity. (shrink)
