ObjectivesResearch has linked mindfulness to improved mental health, yet the mechanisms underlying this relationship are not well understood. This study explored the mediating role of emotion regulation strategies and sleep in the relationship between mindfulness and symptoms of depression, anxiety and psychological distress during the COVID-19 pandemic.MethodsAs detailed in this study’s pre-registration, a cross-sectional research design was used to investigate the impact of mindfulness on mental health and the mediating role of emotion regulation strategies and insomnia. A total of 493 (...) participants from the general population answered an online survey and were included in the final analysis. The online survey consisted of the short form of the Five-Facets Mindfulness Questionnaire, the Impact of Event Scale-revised, the Generalised Anxiety Disorder Scale, the Patient Health Questionnaire, the Emotion Regulation Questionnaire, the short form of the Rumination Response Scale, and the Insomnia Severity Index.ResultsStructural equation modelling revealed that mindfulness was related to lower symptoms of depression, anxiety and psychological distress, both directly and indirectly. Mindfulness was negatively associated with rumination and insomnia. As hypothesised, models revealed that the associations between mindfulness and depression, anxiety and psychological distress were significantly mediated by its negative associations with rumination and insomnia. Our findings also demonstrated that rumination was related to increased insomnia symptoms, which in turn was associated with increased mental health problems, indicating a mediated mediation. Mindfulness was also positively associated with cognitive reappraisal and negatively associated with suppression, which were, respectively, negatively and positively associated with depressive symptoms, and thus functioned as specific mediators of the association between mindfulness and depression.ConclusionOur findings suggest that rumination and insomnia operate transdiagnostically as interrelated mediators of the effects of mindfulness on mental health, whereas cognitive reappraisal and suppression function as specific mediators for depression. These insights emphasise the importance of targeting emotion regulation and sleep in mindfulness interventions for improving mental health. Limitations and implications for practice are discussed.

Immortality is one of the themes of this issue, and thus I would like to talk about two Graeco-Egyptian ceremonies promising the overthrow of death, one of them actually bearing the title apathanatismos, to render immortal. The detailed texts of both ceremonies can be found among the Greek papyri. The standard edition is Karl Preisendanz’ Papyri Magicae Graecae, and they are thus clearly regarded as magical.

Platons Frühdialoge enden alle in der Aporie, in vollständiger Ratlosigkeit. Man hat sich darüber immer gewundert. Der Verfasser vertritt die These, dass diese kleinen Kunstwerke für den Unterricht in Platons Akademie gedacht waren, dass Fragen offen bleiben mussten, um Unterrichtsstoff zu haben, um Diskussionen zu ermöglichen, um die Schüler im Denken/Fragen zu üben etc.

In this new and third edition, the additional fragments contained in the appendix of the second edition have been incorporated in the main text. Some further discoveries have been included, and reference has been made to the results of recent research on the relative placing of certain papyrus fragments. The index of names has been brought up to date.

In the mathematics education research literature, there is a growing body of scholarship on how mathematicians practice their craft. The purpose of this chapter is to survey some of this literature and explain how it can contribute to the philosophy of mathematical practice. We first describe how mathematics educators use empirical methodologies to investigate the behaviors of mathematicians and argue that findings from these studies can inform the philosophy of mathematical practice. We then illustrate this by summarizing research on mathematicians’ (...) understandings and mathematicians’ proof reading. (shrink)

On several levels, there is now a debate whether the concept of God can be made compatible with modern science. In an attempt to elucidate this debate, I give an account of my own experiences from writing a book on the foundation of quantum mechanics. In my opinion, one can give two independent arguments for the existence of God by taking as departure an epistemic (knowledge-based) interpretation of quantum theory. However, I also argue that any religious belief should be the (...) result of an existential choice governed by each person’s own context (history and culture). In particular, I give my account of Christianity as a religion connected to our western culture, how one as a scientist can relate to the relevant dogmas. (shrink)

The well known Bell experiment with two actors Alice and Bob is considered. First the simple deduction leading to the CHSH inequality under local realism is reviewed, and some arguments from the literature are recapitulated. Then I take up certain background themes before I enter a discussion of Alice’s analysis of the situation. An important point is that her mind is limited by the fact that her Hilbert space in this context is two-dimensional. General statements about a mind’s limitation during (...) a decision process are derived from recent results on the reconstruction of quantum theory from conceptual variables. These results apply to any decision situation. Let all the data from the Bell experiment be handed over to a new actor Charlie, who performs a data analysis. But his mind is also limited: He has a four-dimensional Hilbert space in the context determined by the experiment. I show that this implies that neither Alice nor Charlie can have the argument leading to the CHSH inequality as a background for making decisions related to the experiment. Charlie may be any data analyst, and he may communicate with any person. It is argued that no rational person can be convinced by the CHSH argument when making empirical decisions on the Bell situation. (shrink)

Sommaire et accès conditionnel au texte.

This article may be seen as a summary and a final discussion of the work that the author has done in recent years on the foundation of quantum theory. It is shown that quantum mechanics as a model follows under certain specific conditions from a quite different, much simpler model. This model is connected to the mind of an observer, or to the joint minds of a group of communicating observers. The model is based upon conceptual variables, and an important (...) aspect is that an observer (a group of observers) must decide on which variable to measure. The model is then linked more generally to a theory of decisions. The results are discussed from several angles. (shrink)

The objective was to test the Theory of Planned Behavior and the proposition that relative measures should be used in travel mode choice situations. Data from a survey in Norway was analyzed using regression analysis. The results indicated that factors of the Theory of Planned Behavior and past behavior predicted intentions to travel by car, public, transport, bicycle, and on foot. The results supported the idea that there is a split in perceived behavioral control in controllability and self-efficacy, as controllability (...) was a significant predictor only for intention to travel by car. The use of relative measures added to the predictive strength of all predictors and increased prediction of behavioral intention for all travel modes. The results supported the Theory of Planned Behavior and the proposition regarding choice situations. Previous tests of the theory may have underestimated its predictive power. Attitudes, subjective norms, and perceived behavioral control predict travel intentions and may be targeted in interventions aimed at promoting travel mode choice. (shrink)

Inside a combinatory algebra, there are ‘internal’ versions of the finite type structure over ω, which form models of various systems of finite type arithmetic. This paper compares internal representations of the intensional and extensional functionals. If these classes coincide, the algebra is called ft-extensional. Some criteria for ft-extensionality are given and a number of well-known ca's are shown to be ft-extensional, regardless of the particular choice of representation for ω. In particular, DA, Pω, Tω, Hω and certain D∞-models all (...) share the property of ft-extensionality. It is also shown that ft-extensionality is by no means an intrinsic property of ca's i.e., that there exists a very concrete class of ca's—the class of reflexive coherence spaces—no member of which has this property. This leads to a comparison of ft-extensionality with the well-studied notions of extensionality and weak extensionality. Ft-extensionality turns out to be completely independent. (shrink)

I. Egner, “The role of topos in the use of a Wobe particle”.In the paper I am trying to show how a speaker using the particle {ie271-1} in his utterance calls upon a contextual assumption that can be formulated as a topos.After formulating a working hypothesis according to which the particle {ie271-2} signals to the hearer that the speaker's utterance is justified, I use English and Wobe paraphrases of the examples quoted in order to make explicit that justification.Wobe paraphrases given (...) by the informant suggest that in using {ie271-3} the speaker calls upon t contextual assumption that he feels is relevant in the speech situation. To the extent that this assumption is based on common sense knowledge, it seemed appropriate to use Ducrot's notion of topos to formulate it, e.g. (T) [The deeper one gets into the bush, the fewer white people he meets].One of the examples quoted calls attention to the fact that the topos called upon by way of {ie271-4} may or may not be validated, i.e. confirmed in the speech situation.Finally, the validation or non-validation of a topos seems to determine the illocutionary value of a wh-question containing {ie271-5} as request for information or request for explanation respectively.

To build a front against neoliberalism, those in the alter-globalisation movement work across perceived divides. Such transversal openness, however, has not been embraced fully within the academic sphere, even though theoretical coalitions are also important for developing a life-affirming societal ethos. Meaningful opportunities for theoretical bridging do exist, particularly where alternative value systems, hitherto isolated, can be drawn into the wider global dialogue on societal futures. In this spirit, this article offers some transversal reflections on materialist ecofeminism, and one such (...) marginalised value system: the African ethic of ubuntu. (shrink)

A meadow is a commutative ring with an inverse operator satisfying 0⁻¹ = 0. We determine the initial algebra of the meadows of characteristic 0 and prove a normal form theorem for it. As an immediate consequence we obtain the decidability of the closed term problem for meadows and the computability of their initial object.

In this paper we present a logic that determines when implications in a classical logic context express a relevant connection between antecedent and consequent. In contrast with logics in the relevance logic literature, we leave classical negation intact—in the sense that the law of non-contradiction can be used to obtain relevant implications, as long as there is a connection between antecedent and consequent. On the other hand, we give up the requirement that our theory of relevance should be able to (...) define a new standard of deduction. We present and argue for a list of requirements such a logical theory of classical relevance needs to meet and go on to formulate a system that respects each of these requirements. The presented system is a Tarski logic that extends the relevance logic R with a new relevant implication which allows for Disjunctive Syllogism and similar rules. This is achieved by interpreting the logical symbols in the antecedents in a stronger way than the logical symbols in consequents. A proof theory and an algebraic semantics are formulated and interesting metatheorems are proven. Finally we give a philosophical motivation for our non-standard relevant implication and the asymmetric interpretation of antecedents and consequents. (shrink)

In vitro meat is presented by innovators as the most realistic and sustainable solution to the problems of current meat production and consumption. The innovators argue that in vitro meat could be more environmentally friendly, animal friendly, healthier, and safer than conventional meat. The paper elaborates different reactions of experts and stakeholders from science, civil society, economy, and politics to the innovators’ reasoning. The semi-structured interviews were conducted for the project “Visions of in vitro meat. Analysis of technical and societal (...) aspects and visions of in vitro meat” funded by the German Ministry of Education and Research. In this paper we will show how our interview partners positioned themselves in relation to the innovators’ vision on IVM and which other visions they brought into the discussion about IVM and the future of meat. The project was based on a concept of visions as socio-epistemic practices that are increasingly recognised as important elements in innovation and transformation processes. The analysis of these visions conducted in interviews with experts and stakeholders provided new knowledge for the conceptualisation and appraisal of in vitro meat beyond the innovators’ rhetoric.
