Classical particles of the same kind are distinguishable: they can be labeled by their positions and follow different trajectories. This distinguishability affects the number of ways W a macrostate can be realized on the micro-level, and via S=k ln W this leads to a non-extensive expression for the entropy. This result is generally considered wrong because of its inconsistency with thermodynamics. It is sometimes concluded from this inconsistency, notoriously illustrated by the Gibbs paradox, that identical particles must be treated as (...) indistinguishable after all; and even that quantum mechanics is indispensable for making sense of this. In this article we argue, by contrast, that the classical statistics of distinguishable particles and the resulting non-extensive entropy function are perfectly all-right both from a theoretical and an experimental perspective. We remove the inconsistency with thermodynamics by pointing out that the entropy concept in statistical mechanics is not completely identical to the thermodynamical one. Finally, we observe that even identical quantum particles are in some cases distinguishable; and conclude that quantum mechanics is irrelevant to the Gibbs paradox. (shrink)

Online social networks play an increasingly important role in communication between friends, colleagues, business partners, and family members. This development sparked public and scholarly debate about how these new platforms affect dynamics of cultural diversity. Formal models of cultural dissemination are powerful tools to study dynamics of cultural diversity but they are based on assumptions that represent traditional dyadic, face-to-face communication, rather than communication in online social networks. Unlike in models of face-to-face communication, where actors update their cultural traits after (...) being influenced by one of their network contacts, communication in online social networks is often characterized by a one-to-many structure, in that users emit messages directly to a large number of network contacts. Using analytical tools and agent-based simulation, we show that this seemingly subtle difference can have profound implications for emergent dynamics of cultural dissemination. In particular, we show that within the framework of our model online communication fosters cultural diversity to a larger degree than offline communication and it increases chances that individuals and subgroups become culturally isolated from their network contacts.

Mobile health applications (‘health apps’) that promise the user to help her with some aspect of her health are very popular: for-profit apps such as MyFitnessPal, Fitbit, or Headspace have tens of millions of users each. For-profit health apps are designed and run as optimization systems. One would expect that these health apps aim to optimize the health of the user, but in reality they aim to optimize user engagement and, in effect, conversion. This is problematic, I argue, because digital (...) health environments that aim to optimize user engagement risk being manipulative. To develop this argument, I first provide a brief analysis of the underlying business models and the resulting designs of the digital environments provided by popular for-profit health apps. In a second step, I present a concept of manipulation that can help analyze digital environments such as health apps. In the last part of the article, I use my concept of manipulation to analyze the manipulative potential of for-profit health apps. Although for-profit health can certainly empower their users, the conditions for empowerment also largely overlap with the conditions for manipulation. As a result, we should be cautious when embracing the empowerment discourse surrounding health apps. An additional aim of this article is to contribute to the rapidly growing literature on digital choice architectures and the ethics of influencing behavior through such choice architectures. I take health apps to be a paradigmatic example of digital choice architectures that give rise to ethical questions, so my analysis of the manipulative potential of health apps can also inform the larger literature on digital choice architectures.

This paper explores the interrelations between temporality and emotion in rhetorical argumentation. It argues that in situations of uncertainty argumentation affects action via appeals that invoke emotion and thereby translate the distant past and future into the situated present. Using practical inferences, a threefold model for the interrelation of emotion and time in argumentation outlines how argumentative action depends on whether speakers provide reasons for the exigence that makes a decision necessary, the contingency of the decision, and the confidence required (...) to act. Experiences and choices from the past influence the emotions experienced in the present and inform two intertemporal mechanisms that allow speakers and audiences to take the leap of faith that defines decision-making under uncertainty: retrospective forecasting and prospective remembering. Retrospective forecasting establishes a past–future–present link, whereas prospective remembering establishes a future-past-present link, and, together, the two mechanisms provide a situated presence that transcends the temporal constraints of uncertainty. Finally, the applicability of the model is illustrated through an analysis of a speech delivered by Danish Prime Minister Mette Frederiksen at the outset of the COVID-19 pandemic, a time where the need for decisive, yet argumentative action was crucial.

This paper uses a study of the life story narratives of former classmates of Dutch and Moluccan descent to argue that the constructionist approach to intersectionality, with its account of identity as a narrative construction rather than a practice of naming, offers better tools for answering questions concerning intersectional identity formation than a more systemic intersectional approach. The case study also highlights the importance of the quest for origins in narratives. It demonstrates that theories of intersectionality are unjustified in subsuming (...) the issue of belonging under the identity marker of ethnicity, when all identities are performatively produced in and through narrative enactments that include belonging. Belongingness is a precarious achievement. The case study illustrates that if narrative accounts of a life fail to achieve narrative closure regarding roots, attempts to trace routes are seriously hampered. (shrink)

The concept of recognition has been pivotal in critical theory in recent years. This paper discusses how two goals of a critical theory of recognition – to explain and to morally evaluate social change – are interrelated. In doing so, this paper draws the limits of the concept of struggles for recognition. It is argued that if a social movement can be deemed illegitimate, this movement can no longer be understood as struggling for recognition. This implies that the two goals (...) of a critical theory of recognition cannot be fulfilled simultaneously: a moral standard that distinguishes between legitimate and illegitimate social struggles cannot distinguish between different types of struggles for recognition, but only between struggles for recognition and other types of social struggles. Drawing the limits of the concept of struggles for recognition in this way helps to better distinguish between different types of social struggle and contributes to a more precise understanding of what struggles for recognition entail.

News media have transformed over the last decades, there being increasing numbers of online news suppliers and an increase in online news consumption. We examine how reporting on immigration differs between popular German online and print media over three crucial years of the so-called immigration crisis from 2015 to 2017. This study extends knowledge on the framing of the crisis by examining a period covering the start, peak, and time after the intake of refugees. Moreover, we establish whether online and (...) print reporting differs in terms of both frame occurrence and variability. The period of the crisis provided an ideal test to see whether the focus of media reporting differed between online and print sources. Employing a most- similar- cases design based on online and print versions of three major German news outlets, we extract the dominant frames in almost 18,500 articles using algorithm-based topic modelling. While results indicate that many frames are more visible in either online or print media, these differences often do not follow theoretical expectations. Furthermore, online media are dominated by particular frames and, hence, show less diversity than print media. However, important key events happening during our period of investigation do not affect overall diversity of frames. (shrink)

In the early 1990’s, many feminist philosophers found that the practice of the women´s movement as well as those of other new social movements, could be articulated most adequately in terms of citizenship. The classical political vocabulary of citizenship seemed to offer a viable alternative to the vocabularies that until then had been dominant in feminist political theory: the individualistic, rights-oriented discourse of liberalism, and the structuralist, interest-oriented perspectives of socialism and marxism.

We present an analysis of the Frauchiger–Renner Gedankenexperiment from the point of view of the relational interpretation of quantum mechanics. Our analysis shows that the paradox obtained by Frauchiger and Renner disappears if one rejects promoting one agent’s certainty to another agent’s certainty when it cannot be validated by records from the past. A by-product of our analysis is an interaction-free detection scheme for the existence of such records.

Saunders has recently claimed that “identical quantum particles” with an anti-symmetric state (fermions) are weakly discernible objects, just like irreflexively related ordinary objects in situations with perfect symmetry (Black’s spheres, for example). Weakly discernible objects have all their qualitative properties in common but nevertheless differ from each other by virtue of (a generalized version of) Leibniz’s principle, since they stand in relations an entity cannot have to itself. This notion of weak discernibility has been criticized as question begging, but we (...) defend and accept it for classical cases likes Black’s spheres. We argue, however, that the quantum mechanical case is different. Here the application of the notion of weak discernibility indeed is question begging and in conflict with standard interpretational ideas. We conclude that the introduction of the conceptual resource of weak discernibility does not change the interpretational status quo in quantum mechanics. (shrink)

La méthodologie de Hobbes est interprétée par la plupart des commentateurs en termes de l'idéal scientifique moderne comme celui-ci fut exprimé par exemple par Galilée. Cependant, en ce qui concerne son approche purement méthodologique, tant du problème de la vérité que de celui de la certitude, et son ambiguïté vis-à-vis du rôle épistémologique de l'expérience, sa méthodologie paraît beaucoup plus apparentée aux conceptions méthodologiques, inspirées par les mathématiques grecques, de certains aristotéliciens éclectiques du seizième et de la première moitié du (...) dix-septième siècle. Cette affinité se manifeste notamment dans les conceptions de Hobbes concernant le rapport entre les sciences théoriques et appliquées, dans sa plaidoirie pour la méthode axiomatiquedeductive des géomètres comme le procédé logique par excellence, et dans son idéal d'un système cohérent des sciences qui, se basant sur la philosophie première au sens d'une nomenclature adéquate des choses, obtient principalement son unité de la méthode.

Social media (SM) influence young adults’ communication practices. Artificial Intelligence (AI) is increasingly used for making recommendations on SM. Yet, its effects on different generations of SM users are unknown. SM can use AI recommendations to sort texts and prioritize them, shaping users’ online and offline experiences. Current literature primarily addresses technological or human-user perspectives, overlooking cognitive perspectives. This research aims to propose methods for mapping users’ interactions with AI recommendations (AiRS) and analyzes how embodied interactions mediated by a digital (...) agent can lead to changes in social and cultural practices. For this, this work proposes a comparative analysis of central practices evoked by AI recommendations-mediated communication on SM among users in Italy, Estonia, and the Netherlands in the age category 18–26 years old. The data used in the comparative analysis was collected via semi-structured interviews and elaborated based on cognitive psychology and semiotics. This research highlights the contextual significance of AI recommendations as a mediator in creating new communication practices. Findings confirm that young adults often choose practices that would enhance their digital representations according to AiRS’ dominant patterns and categories. AiRS impacts individual interpretations and practices and can further affect social and cultural levels. (shrink)

Spatiality, Sovereignty and Carl Schmitt: Geographies of the Nomosis an edited volume by Stephen Legg. The book was published in the midst of accruing attention to the issues of space and order in the writings of Carl Schmitt. The objective of the book must, therefore, be understood as a critical analysis of the different ways Schmitt’s concepts can inform and have informed the study of geopolitics. This review will provide a critical summary of the main themes in the book and (...) analyse the arguments made for and against using Schmitt. I will additionally assess the ways in which Marxist Geography can benefit from critically engaging with Schmitt. It will be argued that a critical engagement with Schmitt should start from a contextualised position and a subsequent fertile negation of his thinking. (shrink)

This paper compares two recent public debates in the Netherlands: the debate initiated by Ayaan Hirsi Ali on the position of Muslim women on the one hand, and discussions regarding the situation of female sex workers since the legalization of Dutch prostitution in 2000 on the other. It is argued that liberal public policies should not always be guided by the unconditional respect for the autonomy of (adult) citizens, but that it sometimes seems wiser to adopt an attitude of sympathetic (...) distrust regarding practices of which one has good reasons to suspect that they are harmful to the women involved.

Propositional logic has been recognized throughout the centuries as one of the cornerstones of reasoning in philosophy and mathematics. Over time, its formalization into Boolean algebra was accompanied by the recognition that a wide range of combinatorial problems can be expressed as propositional satisfiability (SAT) problems. Because of this dual role, SAT developed into a mature, multi-faceted scientific discipline, and from the earliest days of computing a search was underway to discover how to solve SAT problems in an automated fashion. (...) This book, the Handbook of Satisfiability, is the second, updated and revised edition of the book first published in 2009 under the same name. The handbook aims to capture the full breadth and depth of SAT and to bring together significant progress and advances in automated solving. Topics covered span practical and theoretical research on SAT and its applications and include search algorithms, heuristics, analysis of algorithms, hard instances, randomized formulae, problem encodings, industrial applications, solvers, simplifiers, tools, case studies and empirical results. SAT is interpreted in a broad sense, so as well as propositional satisfiability, there are chapters covering the domain of quantified Boolean formulae (QBF), constraints programming techniques (CSP) for word-level problems and their propositional encoding, and satisfiability modulo theories (SMT). An extensive bibliography completes each chapter. This second edition of the handbook will be of interest to researchers, graduate students, final-year undergraduates, and practitioners using or contributing to SAT, and will provide both an inspiration and a rich resource for their work. Edmund Clarke, 2007 ACM Turing Award Recipient: "SAT solving is a key technology for 21st century computer science." Donald Knuth, 1974 ACM Turing Award Recipient: "SAT is evidently a killer app, because it is key to the solution of so many other problems." Stephen Cook, 1982 ACM Turing Award Recipient: "The SAT problem is at the core of arguably the most fundamental question in computer science: What makes a problem hard?". (shrink)

This study argues that contemporary theology needs a reconceptualised form of metaphysical theology to readdress this question of universality. In order to develop such a new metaphysical theology, de Jong turns to the work of Karl Rahner and Edward Schillebeeckx. Presenting a new perspective on their theological methods, he demonstrates that these theologians employ a dialectical interplay of hermeneutical and metaphysical arguments yielding a modest theological metaphysics. Crucially, these thinkers recognise that acknowledging hermeneutical conditions does not need to end in (...) particularism. Instead, Rahner and Schillebeeckx argue that the infinite variety of particular human experiences can act as potential encounters with the universally self-revealing God. Retrieving these modest forms of theological metaphysics reminds contemporary theology that it is possible to think about universality from within particularity. Balancing the intelligible and mysterious nature of God, Rahner and Schillebeeckx show how a modest theological metaphysics contains its own self-critical hermeneutical disciplining. This renewed understanding about the earlier use of metaphysics opens up new avenues of thought for fundamental theologians that do not want to shy away from the difficult question of the universality of God.
