The COVID-19 pandemic has negatively impacted mobility worldwide. As a corollary, the health of top- and lower-level athletes alike is profoundly reliant on movement and exercise. Thus, the aim of this study is to understand impacts of the COVID-19 pandemic lockdown on athletes’ motivation to exercise and train. In detail, we aim to better understand who reported a change in motivation to train due to the lockdown, why they reported lower motivation, what they did to help themselves, what support they (...) received from others, and what they are looking forward to after the lockdown. Questionnaire data and answers to these open-ended questions were assessed via an online questionnaire, completed by 95 amateur and recreational athletes during the first COVID-19 lockdown in Germany. Results show that greater numbers of female athletes are less motivated to train in comparison to male athletes. No differences in motivation were found regarding type of sport and number of competitions during the year. Also, more motivated to train amateur and recreational athletes showed lower athletic identity than athletes who reported no change in motivation to exercise during the lockdown. Additionally, differences in state emotional, perceived stress, and personality variables were found between athletes who stated that they were less motivated to train compared to athletes who reported no changes in motivation. In particular, closure of sports facilities and social distancing measures were perceived to be highly problematic. Even though athletes received emotional support, organized themselves via routines and schedules, and trained using online tools, they predominately stated that they wished that their coaches would have supported them more. Understanding the impacts of a pandemic-related lockdown on athletes’ motivation, athletes’ coping strategies, and their desired support will help better support them in future crises. (shrink)

It is generally believed that moral reductionism is immune from notorious problems in moral metaphysics and epistemology, such as the problem of moral explanation – it is at least on this dimension that moral reductionism scores better than moral anti- reductionism. However, in this article I reject this popular view. First, I argue that moral reductionism fails to help vindicate the explanatory efficacy of moral properties because the reductionist solution is either circular or otiose. Second, I attempt to show that (...) a successful vindication, if any, of moral explanation requires moral-descriptive irreducibility. My discussion thus raises an explanatory challenge to moral reductionism. (shrink)

What is morality? How many moral values are there? And what are they? According to the theory of morality-as-cooperation, morality is a collection of biological and cultural solutions to the problems of cooperation recurrent in human social life. This theory predicts that there will be as many different types of morality as there are different types of cooperation. Previous research, drawing on evolutionary game theory, has identified at least seven different types of cooperation, and used them to explain seven different (...) types of morality: family values, group loyalty, reciprocity, heroism, deference, fairness and property rights. Here we explore the conjecture that these simple moral ‘elements’ combine to form a much larger number of more complex moral ‘molecules’, and that as such morality is a combinatorial system. For each combination of two elements, we hypothesise a candidate moral molecule, and successfully locate an example of it in the professional and popular literature. These molecules include: fraternity, blood revenge, family pride, filial piety, gavelkind, primogeniture, friendship, patriotism, tribute, diplomacy, common ownership, honour, confession, turn taking, restitution, modesty, mercy, munificence, arbitration, mendicancy, and queuing. These findings indicate that morality – like many other physical, biological, psychological and cultural systems – is indeed a combinatorial system. Thus morality-as-cooperation provides a principled and powerful theory, that explains why there are many moral values, and successfully predicts what they will be; and it generates a systematic framework that has the potential to explain all moral ideas, possible and actual. Pursuing the many implications of this theory will help to place the study of morality on a more secure scientific footing. (shrink)

This paper reviews the hole argument as an argument against spacetime substantivalism. After a careful presentation of the argument itself, I critically review possible responses.

The problems of evil and suffering have been extensively discussed in Jewish philosophy, and much of the discussion has centred on the Book of Job. In this study Oliver Leaman poses two questions: how can a powerful and caring deity allow terrible things to happen to obviously innocent people, and why have the Jewish people been so harshly treated throughout history, given their status as the chosen people? He explores these issues through an analysis of the views of Philo, (...) Saadya, Maimonides, Gersonides, Spinoza, Mendelssohn, Hermann Cohen, Buber, Rosenzweig, and post-Holocaust thinkers, and suggests that a discussion of evil and suffering is really a discussion about our relationship with God.

Explainable artificial intelligence (XAI) seeks to produce explanations for those machine learning methods which are deemed opaque. However, there is considerable disagreement about what this means and how to achieve it. Authors disagree on what should be explained (topic), to whom something should be explained (stakeholder), how something should be explained (instrument), and why something should be explained (goal). In this paper, I employ insights from means-end epistemology to structure the field. According to means-end epistemology, different means ought to be (...) rationally adopted to achieve different epistemic ends. Applied to XAI, different topics, stakeholders, and goals thus require different instruments. I call this the means-end account of XAI. The means-end account has a descriptive and a normative component: on the one hand, I show how the specific means-end relations give rise to a taxonomy of existing contributions to the field of XAI; on the other hand, I argue that the suitability of XAI methods can be assessed by analyzing whether they are prescribed by a given topic, stakeholder, and goal.

English has plural terms as well as singular terms. But our standard formal languages, e.g., the predicate calculus, feature only singular terms. How can the plural idiom be formalized?‘Changing the subject’ is by far the most common plurals strategy among both philosophers and linguists: a plural term is replaced by a singular term standing for some complex object that ‘contains’ the individuals to which the plural term alludes. For example, one might simply replace ‘A, B imply C’ with ‘{A, B} (...) implies [singular] C’. We uncover a surprising variety of ways to change the subject, of ever‐increasing complexity and ingenuity. Our question is whether any can made to work. (shrink)

The pandemic has catalysed to hasten the wider use of virtual hearings in international arbitration. However, the promotion of virtual hearings in international commercial dispute resolution was more complex than commonly thought due to the highlighted concerns of cybersecurity and breach of confidentiality in arbitration. The worries against the wide use of virtual hearings cannot stand because technological innovations can largely improve and solve this. However, virtual arbitration hearings may not be common post-COVID times. Technology shapes how people behave, interact, (...) grow, and develop in their relationships with others and wider communities. Yet greater immersion in the digital world undoubtedly creates new challenges and can adversely affect human-to-human interactions. There is very little scientific study on the psychological impacts of virtual hearings on arbitrators, witnesses and counsels. It is too early to assess its effectiveness from the user's perspective until the much-needed scientific data is released. Virtual hearings are unlikely to replace in-person ones necessary for more complex and high-value disputes requiring greater interaction and personal connection. Strategically, international arbitration is a private initiative-orientated, flexible, and market-driven dispute resolution mechanism. The parties are best positioned to choose the hearing format after balancing off. (shrink)

Substantivalists believe that spacetime and its parts are fundamental constituents of reality. Relationalists deny this, claiming that spacetime enjoys only a derivative existence. I begin by describing how the Galilean symmetries of Newtonian physics tell against both Newton's brand of substantivalism and the most obvious relationalist alternative. I then review the obvious substantivalist response to the problem, which is to ditch substantival space for substantival spacetime. The resulting position has many affinities with what are arguably the most natural interpretations of (...) special and general relativity. I move on to consider and reject two recent antisubstantivalist lines of thought. The interim conclusion is that the best argument for relationalism is an appeal to Ockham's razor. However, for this to be successful there must be genuine relationalist theories that share the theoretical virtues of their substantivalist rivals but without the additional ontological commitment. The bulk of the paper is therefore an investigation of various concrete relationalist proposals. I distinguish three options for the relationalist in the face of the success of Galilean invariant physics and trace how these generalise to relativistic physics. One of the options is particularly promising but, since its basic objects end up being spacetime points, this does not help the prospects of relationalism as traditionally conceived. I end with some reflections on the fate of substantivalism in the aftermath of the Hole Argument, concluding that we have as yet to be given good reasons to abandon the natural, substantivalist interpretation of current physics.

One of postmodernism's toughest challenges to Christian thought is its wholesale rejection of metaphysics. This profound book meets the challenge squarely, offering a surer foundation for the idea of being and a new theological perspective of supreme relevance to today's world. In a brilliant turn of postmodern thought itself, Oliver Davies argues for a renewal of metaphysics based on a dynamic new understanding of ontology as narrative and performance. His repairing of the Western metaphysical tradition is grounded both in (...) the divine self-naming in Exodus -- which, for the rabbis, identified God's presence in the world with God's compassionate acts -- and in the compassionate resistance of Etty Hillesum and Edith Stein to the violence of the Holocaust. Building on a new metaphysics of compassion that is attentive to the deepest histories of the contemporary world, Davies offers a renewed systematic theology focused on divine speech and God's compassionate relation to human culture.

The study of dialectical logic has a history of nearly one hundred years in China. It is significant for understanding both the growth of Chinese logic and the Sinicization of Marxism to review dialectical logic in the context of introducing the study of Marxism in China. Debates about dialectical logic in Chinese academic circles involve not only the problems of logic itself, but more importantly the understanding of Marxist philosophy. In the 1920s and 1930s, some Marxist researchers in China were (...) influenced by the philosophers and logicians of the former Soviet Union, and they came very close to equating dialectical logic with Marxist dialectics. They also identified the formal logic originating from ancient Greece as metaphysics, praising the former and criticizing the latter. In the upsurge of Marxist philosophy in the 1950s and 1960s, Chinese logicians carried out normal and formal academic research on dialectical logic. During the period from the end of 1970s to the end of 1990s, the research and teaching of dialectical logic in China reached its heyday, and logicians performed comprehensive and detailed research on some critical issues, including the basic laws of dialectical logic, which they tried to formalize. Since the beginning of the 21st century, dialectical logic has ceased to prosper and has faded from the core field of the discipline of logic, although some honorable scholars still persist in studying it.

Immanuel Kant is often considered to be the source of the contemporary idea of human dignity, but his conception of human dignity and its relation to human value and to the requirement to respect others have not been widely understood. Kant on Human Dignity offers the first in-depth study in English of this subject. Based on a comprehensive analysis of all the passages in which Kant uses the term ;dignity, as well as an analysis of the most prominent arguments for (...) a value of human beings in the Kant literature, the book carefully examines different ways of construing the relationship between dignity, value and respect for others. It takes seriously Kant s Copernican Revolution in moral philosophy: Kant argues that moral imperatives cannot be based on any values without yielding heteronomy. Instead it is imperatives of reason that determine what is valuable. The requirement to respect all human beings is one such imperative. Respect for human beings does not follow from human dignity for this would violate autonomy but is an unconditional command of reason. Following this train of thought yields a unified account of Kant s moral philosophy. (shrink)

Philosophy in the English-speaking world is dominated by analytic approaches to its problems and projects; but theology has been dominated by alternative approaches. Many would say that the current state in theology is not mere historical accident, but is, rather, how things ought to be. On the other hand, many others would say precisely the opposite: that theology as a discipline has been beguiled and taken captive by 'continental' approaches, and that the effects on the discipline have been largely deleterious. (...) The methodological divide between systematic theologians and analytic philosophers of religion is ripe for exploration. The present volume represents an attempt to begin a much-needed interdisciplinary conversation about the value of analytic philosophical approaches to theological topics. Most of the essays herein are sympathetic toward the enterprise the editors are calling analytic theology; but, with an eye toward balance, the volume also includes essays and an introduction that try to offer more critical perspectives on analytic theology.

Cooperation requires that individuals are able to identify, and preferentially associate with, others who have compatible preferences and the shared background knowledge needed to solve interpersonal coordination problems. The present study investigates the nature of such similarity within social networks, asking: What do friends have in common? And what is the relationship between similarity and altruism? The results show that similarity declines with frequency of contact; similarity in general is a significant predictor of altruism and emotional closeness; and, specifically, sharing (...) a sense of humor, hobbies and interests, moral beliefs, and being from the same area are the best predictors. These results shed light on the structure of relationships within networks and provide a possible checklist for predicting attitudes toward strangers, and in-group identification. (shrink)

Ever since Eve tempted Adam with her apple, women have been regarded as a corrupting and destructive force. The very idea that women can be used as interrogation tools, as evidenced in the infamous Abu Ghraib torture photos, plays on age-old fears of women as sexually threatening weapons, and therefore the literal explosion of women onto the war scene should come as no surprise. From the female soldiers involved in Abu Ghraib to Palestinian women suicide bombers, women and their bodies (...) have become powerful weapons in the Afghanistan and Iraq wars. In _Women as Weapons of War_, Kelly Oliver reveals how the media and the administration frequently use metaphors of weaponry to describe women and female sexuality and forge a deliberate link between notions of vulnerability and images of violence. Focusing specifically on the U.S. campaigns in Afghanistan and Iraq, Oliver analyzes contemporary discourse surrounding women, sex, and gender and the use of women to justify America's decision to go to war. For example, the administration's call to liberate "women of cover," suggesting a woman's right to _bare_ arms is a sign of freedom and progress. Oliver also considers what forms of cultural meaning, or lack of meaning, could cause both the guiltlessness demonstrated by female soldiers at Abu Ghraib and the profound commitment to death made by suicide bombers. She examines the pleasure taken in violence and the passion for death exhibited by these women and what kind of contexts created them. In conclusion, Oliver diagnoses our cultural fascination with sex, violence, and death and its relationship with live news coverage and embedded reporting, which naturalizes horrific events and stymies critical reflection. This process, she argues, further compromises the borders between fantasy and reality, fueling a kind of paranoid patriotism that results in extreme forms of violence. (shrink)

Generative AI has gained a lot of attention in society, business, and science. This trend has increased since 2018, and the big breakthrough came in 2022. In particular, AI-based text and image generators are now widely used. This raises a variety of ethical issues. The present paper first gives an introduction to generative AI and then to applied ethics in this context. Three specific image generators are presented: DALL-E 2, Stable Diffusion, and Midjourney. The author goes into technical details and (...) basic principles, and compares their similarities and differences. This is followed by an ethical discussion. The paper addresses not only risks, but opportunities for generative AI. A summary with an outlook rounds off the article. (shrink)

As a linguist, Julia Kristeva has pioneered a revolutionary theory of the sign in its relation to social and political emancipation; as a practicing psychoanalyst, she has produced work on the nature of the human subject and sexuality, and on the "new maladies" of today's neurotic. _The Portable Kristeva_ is the only fully comprehensive compilation of Kristeva's key writings. The second edition includes added material from Kristeva's most important works of the past five years, including _The Sense and Non-Sense of (...) Revolt_, _Intimate Revolt_, and _Hannah Arendt_. Editor Kelly Oliver has also added new material to the introduction, summarizing Kristeva's latest intellectual endeavors and updating the bibliography. (shrink)

Despite its importance in the history of philosophy, the work of the Spanish thinker Averro"es (1126-1198) has been left largely unexplored in this century. This book is the only general account of Averro"es' philosophy in English. Leaman analyzes his thought and influence, particularly his metaphysics and theory of meaning, arguing that while his work belongs within the cultural and political context of medieval Islam, it remains of considerable philosophical and historical significance.

Is the objective passage of time compatible with relativistic physics? There are two easy routes to an affirmative answer: (1) provide a deflationary analysis of passage compatible with the block universe, or (2) argue that a privileged global present is compatible with relativity. (1) does not take passage seriously. (2) does not take relativity seriously. This paper is concerned with the viability of views that seek to take both passage and relativity seriously. The investigation proceeds by considering how traditional A-theoretic (...) conceptions of passage might be generalized to relativistic space-times without incorporating a privileged global present. I argue that the most promising position marries the idea that open possibilities for the future are settled as time passes with a ‘non-standard’ interpretation of the relevant formal models.

John Earman's recent proposal that a substantive version of general covariance consists in the requirement that diffeomorphism invariance be a gauge symmetry is critically assessed. I argue that such a principle does not serve to differentiate general relativity from pre-relativistic theories. A model-theoretic characterization of two formulations of specially-relativistic theories is suggested. Diffeomorphisms are symmetries of only one such style of formulation and, I argue, Earman's proposal does not provide a reason to deny diffeomorphisms the status of gauge transformations relative (...) to this formulation. Carlo Rovelli's distinction between "passive" and "active" diffeomorphism invariance is also clarified. (shrink)

In his paper ``What is Structural Realism?'' James Ladyman drew a distinction between epistemological structural realism and metaphysical (or ontic) structural realism. He also drew a suggestive analogy between the perennial debate between substantivalist and relationalist interpretations of spacetime on the one hand, and the debate about whether quantum mechanics treats identical particles as individuals or as `non-individuals' on the other. In both cases, Ladyman's suggestion is that an ontic structural realist interpretation of the physics might be just what is (...) needed to overcome the stalemate. The main thesis of this paper is that, whatever the interpretative difficulties of generally covariant spacetime physics are, they do not support or suggest structural realism. In particular, I hope to show that there is in fact no analogy that supports a similar interpretation of the metaphysics of spacetime points and of quantum particles. (shrink)

The automated valuation of benchmark land price plays an essential role in regulating land demand in Chinese real-estate market as the big data are currently accumulated rapidly. However, this problem becomes highly challenging due to the multidimension, large volume, and nonlinearity of the land price-influencing factors. In this paper, an effective data-driven automated valuation framework is proposed for valuing real estate assets by combining a GIS and neural network technologies. This framework can automatically obtain the values of spatial factors affecting (...) land price from GIS and generate training set data for training the neural network to identify the complex relationship between all kinds of factors and benchmark land prices. The effectiveness and universality of the framework is verified via the data of benchmark land prices in Wuhan. The framework can be applied for automated benchmark land price valuation in other cities. (shrink)

PurposeThe purpose of this paper is to add one further value to the previously articulated “universal values” and to describe the constituent components of three universal values.Design/methodology/approachThis interpretive/constructivist study of Australia's largest online community of seniors involved a 30‐month ethnographic investigation. After an initial period of 11 months of observing social interaction on the entire site, in‐depth, semi‐structured interviews were conducted with 30 participants, selected according to criterion sampling, a form of purposive sampling.FindingsFour key moral values were identified: equality, freedom, (...) respect and trust. All of them had been found in other studies, with equality and respect (as human dignity) identified as universal values. The findings from this study suggest that freedom is another universal value.Originality/valueThis study extends the understanding of universal values to include freedom. Further, it demonstrates the constituent components for freedom, and those of two other universal values previously identified in the literature, equality and human dignity, as well as revealing linkages between these three values.

This study uses an integrated model of resource conservation theory and social learning theory to explore the antecedents of hotel interns’ perceptions of occupational stigma and to explore the mechanisms inherent to retention willingness. This study first manipulated relevant subjects’ experimental materials through a contextual experiment and used a one-way ANOVA to test the effects of competence stereotypes and occupational stereotypes on hotel interns’ stigma perceptions, respectively, and then used partial least squares structural equation modeling as a statistical tool and (...) the SmartPLS 3.0 program to validate the model of hotel interns’ occupational stigma perceptions-intention. The effects of both competence stereotypes and occupational stereotypes on hotel interns’ perceptions of occupational stigma were significant. The results of the partial least squares structural equation model showed that hotel interns’ perceptions of occupational stigma significantly contributed to emotional exhaustion and that emotional exhaustion significantly influenced hotel interns’ retention willingness, hotel interns’ perceptions of occupational stigma had a significant effect on their retention willingness, while the role of emotional exhaustion as a mediating variable and occupational commitment as a moderator. The inner psychological and behavioral linkage mechanisms of hotel interns’ occupational stigma perceptions and their retention willingness under COVID-19 were explored, and the resource dynamics operating mechanism and professional commitment were also confirmed.

Diffeomorphism invariance is sometimes taken to be a criterion of background independence. This claim is commonly accompanied by a second, that the genuine physical magnitudes (the ``observables'') of background-independent theories and those of background-dependent (non-diffeomorphism-invariant) theories are essentially different in nature. I argue against both claims. Background-dependent theories can be formulated in a diffeomorphism-invariant manner. This suggests that the nature of the physical magnitudes of relevantly analogous theories (one background free, the other background dependent) is essentially the same. The temptation (...) to think otherwise stems from a misunderstanding of the meaning of spacetime coordinates in background-dependent theories. (shrink)

We make some remarks on the mathematics and metaphysics of the hole argument, in response to a recent article in this journal by Weatherall ([2018]). Broadly speaking, we defend the mainstream philosophical literature from the claim that correct usage of the mathematics of general relativity `blocks' the argument.

Recent advances in evolutionary biology and ethology suggest that humans are not the only species capable of empathy and possibly morality. These findings are of no little consequence for theology, given that a nonhuman animal as a free moral agent would beg the question if human beings are indeed uniquely created in God's image. I argue that apes and some other mammals have moral agency and that a traditional interpretation of the imago Dei is incorrectly equating specialness with exclusivity. By (...) framing the problem in terms of metaphor, following the work of Paul Ricoeur and Sallie McFague, I propose that the concept of the imago Dei could be extended to accommodate moral species other than our own.

The synthetization of voices, or speech synthesis, has been an object of interest for centuries. It is mostly realized with a text-to-speech system, an automaton that interprets and reads aloud. This system refers to text available for instance on a website or in a book, or entered via popup menu on the website. Today, just a few minutes of samples are enough to be able to imitate a speaker convincingly in all kinds of statements. This article abstracts from actual products (...) and actual technological realization. Rather, after a short historical outline of the synthetization of voices, exemplary applications of this kind of technology are gathered for promoting the development, and potential applications are discussed critically to be able to limit them if necessary. The ethical and legal challenges should not be underestimated, in particular with regard to informational and personal autonomy and the trustworthiness of media. (shrink)

This book is a critical introduction to contemporary French philosopher Jacques Rancière. It is the first introduction in any language to cover all of his major work and offers an accessible presentation and searching evaluation of his significant contributions to the fields of politics, pedagogy, history, literature, film theory and aesthetics. This book traces the emergence of Rancière’s thought over the last forty-five years and situates it in the diverse intellectual contexts in which it intervenes. Beginning with his egalitarian critique (...) of his former teacher Louis Althusser, the book tracks the subsequent elaboration of Rancière’s highly original conception of equality. This approach reveals that a grasp of his early archival and historiographical work is vital for a full understanding both of his later politics and his ongoing investigation of art and aesthetics. Along the way, this book explains and analyses key terms in Rancière’s very distinctive philosophical lexicon, including the ‘police’ order, ‘disagreement’, ‘political subjectivation’, ‘literarity’, the ‘part which has no part’, the ‘regimes of art’ and ‘the distribution of the sensory’. This book argues that Rancière’s work sets a new standard in contestatory critique and concludes by reflecting on the philosophical and policy implications of his singular project. (shrink)

Point-of-interest recommendations are a popular form of personalized service in which users share their POI location and related content with their contacts in location-based social networks. The similarity and relatedness between users of the same POI type are frequently used for trajectory retrieval, but most of the existing works rely on the explicit characteristics from all users’ check-in records without considering individual activities. We propose a POI recommendation method that attempts to optimally recommend POI types to serve multiple users. The (...) proposed method aims to predict destination POIs of a user and search for similar users of the same regions of interest, thus optimizing the user acceptance rate for each recommendation. The proposed method also employs the variable-order Markov model to determine the distribution of a user’s POIs based on his or her travel histories in LBSNs. To further enhance the user’s experience, we also apply linear discriminant analysis to cluster the topics related to “Travel” and connect to users with social links or similar interests. The probability of POIs based on users’ historical trip data and interests in the same topics can be calculated. The system then provides a list of the recommended destination POIs ranked by their probabilities. We demonstrate that our work outperforms collaborative-filtering-based and other methods using two real-world datasets from New York City. Experimental results show that the proposed method is better than other models in terms of both accuracy and recall. The proposed POI recommendation algorithms can be deployed in certain online transportation systems and can serve over 100,000 users. (shrink)
