A central area of current philosophical debate in the foundations of mathematics concerns whether or not there is a single, maximal, universe of set theory. Universists maintain that there is such a universe, while Multiversists argue that there are many universes, no one of which is ontologically privileged. Often model-theoretic constructions that add sets to models are cited as evidence in favour of the latter. This paper informs this debate by developing a way for a Universist to interpret talk that (...) seems to necessitate the addition of sets to V. We argue that, despite the prima facie incoherence of such talk for the Universist, she nonetheless has reason to try and provide interpretation of this discourse. We present a method of interpreting extension-talk (V-logic), and show how it captures satisfaction in `ideal' outer models and relates to impredicative class theories. We provide some reasons to regard the technique as philosophically virtuous, and argue that it opens new doors to philosophical and mathematical discussions for the Universist. (shrink)

We review different conceptions of the set-theoretic multiverse and evaluate their features and strengths. In Sect. 1, we set the stage by briefly discussing the opposition between the ‘universe view’ and the ‘multiverse view’. Furthermore, we propose to classify multiverse conceptions in terms of their adherence to some form of mathematical realism. In Sect. 2, we use this classification to review four major conceptions. Finally, in Sect. 3, we focus on the distinction between actualism and potentialism with regard to the (...) universe of sets, then we discuss the Zermelian view, featuring a ‘vertical’ multiverse, and give special attention to this multiverse conception in light of the hyperuniverse programme introduced in Arrigoni and Friedman (2013). We argue that the distinctive feature of the multiverse conception chosen for the hyperuniverse programme is its utility for finding new candidates for axioms of set theory. (shrink)

Corporate volunteering is known to be an effective employee engagement initiative. However, despite the prominence of corporate social responsibility in academia and practice, research is yet to investigate whether and how CV may influence consumer perceptions of CSR image and subsequent consumer behaviour. Data collected using an online survey in Australia show perceived familiarity with a company’s CV programme to positively impact CSR image and firm image, partially mediated by others-centred attributions. CSR image, in turn, strengthens affective and cognitive loyalty (...) as well as word-of-mouth. Further analysis reveals the moderating effect of perceived leveraging of the corporate volunteering programme, customer status and the value individuals place on CSR. The paper concludes with theoretical and managerial implications, as well as an agenda for future research. (shrink)

In this article we show that Morse-Kelley class theory provides us with an adequate framework for class forcing. We give a rigorous definition of class forcing in a model \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document} $$$$ \end{document} of MK, the main result being that the Definability Lemma can be proven without restricting the notion of forcing. Furthermore we show under which conditions the axioms are preserved. We conclude by proving that Laver’s Theorem does not hold for (...) class forcings. (shrink)

Ethics has become increasingly prominent in business education and educational research. With a prolific research stream developing in the area of business ethics teaching, our understanding of related approaches and issues has deepened. While researchers focus on the holistic approach to teaching business ethics, specific knowledge about teaching methods in this area remains sparse. This paper discusses an innovative approach to the case method, called case development, and its preliminary assessment in a postgraduate marketing ethics course. Groups of students were (...) asked to research a chosen marketing ethics topic, develop a case study as part of their assessment and to subsequently analyse and present it to the class. Based on an initial assessment by means of a student survey, case development emerged as beneficial in terms of student learning and experience. Following a discussion of the approach and related results, the paper concludes withrecommendations and directions for future research. (shrink)

We investigate how the selection of assurance topics and the format of their communication influence the credibility perception of sustainability report readers. This is important because misleading communication may discredit ethical sustainability assurance practices. Based on signaling theory and using an experimental approach, we are the first to examine false credibility signals in the context of sustainability assurance. We find that two variables related to sustainability assurance, reference explicitness and assurance depth, jointly influence the assurance signal and the perceived credibility (...) of a sustainability report. Our findings indicate that readers are not at risk of false signaling but can make incorrect interpretations of the assurance signal and might respond negatively to well-intentioned signals. The main implications of our findings are that firms should refrain from increasing reference explicitness and should select only the most material topics. Taken together, our results provide new insights on the unethical practice of false signaling and provide an example of an incorrect signal interpretation by readers. (shrink)

In the late 1940s and early 1950s Lorenzen developed his operative logic and mathematics, a form of constructive mathematics. Nowadays this is mostly seen as the precursor to the more well-known dialogical logic and one could assumed that the same philosophical motivations were present in both works. However we want to show that this is not always the case. In particular, we claim, that Lorenzen’s well-known rejection of the actual infinite as stated in Lorenzen (1957) was not a major motivation (...) for operative logic and mathematics. In this article, we claim that this is in fact not the case. Rather, we argue for a shift that happened in Lorenzen’s treatment of the infinite from the early to the late 1950s. His early motivation for the development of operativism is concerned with a critique of the Cantorian notion of set and related questions about the notion of countability and uncountability; only later, his motivation switches to focusing on the concept of infinity and the debate about actual and potential infinity.

In this article we introduce and study hyperclass-forcing in the context of an extension of Morse-Kelley class theory, called MK∗∗. We define this forcing by using a symmetry between MK∗∗ models and models of ZFC− plus there exists a strongly inaccessible cardinal. We develop a coding between β-models ℳ\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document} $$\mathcal {M}$$ \end{document} of MK∗∗ and transitive models M+ of SetMK∗∗ which will allow us to go from ℳ\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} (...) \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document} $$\mathcal {M}$$ \end{document} to M+ and vice versa. So instead of forcing with a hyperclass in MK∗∗ we can force over the corresponding SetMK∗∗ model with a class of conditions. For class-forcing to work in the context of ZFC− we show that the SetMK∗∗ model M+ can be forced to look like Lκ∗[X]\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document} $$L_{\kappa ^*}[X]$$ \end{document}, where κ∗ is the height of M+, κ strongly inaccessible in M+ and X ⊆ κ. Over such a model we can apply definable class forcing and we arrive at an extension of M+ from which we can go back to the corresponding β-model of MK∗∗, which will in turn be an extension of the original ℳ\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document} $$\mathcal {M}$$ \end{document}. Our main result combines hyperclass forcing with coding methods of Beller et al. and Friedman to show that every β-model of MK∗∗ can be extended to a minimal such model of MK∗∗ with the same ordinals. A simpler version of the proof also provides a new and analogous minimality result for models of second-order arithmetic. (shrink)

This article explores journalistic representations of mothers during the horrific ‘Remedia Affair’, a 2003 tragedy in which dozens of Jewish Israeli babies fell sick and five died after being fed defective infant formula. The affair, a significant event in Israel’s collective memory, was narrativized as a ‘media scandal’ with multiple discourses of guilt, blame and victimhood. Analysis of the linguistic and visual coverage of Jewish Israeli mothers in six newspapers shows how mothers were reconstructed as guilty for the loss of (...) the babies’ lives and well-being. In addition, the mothers were called to ‘come back’ to breastfeeding, an act that could have saved their children. Overall, this coverage reaffirmed the traditional social norms of the ‘ideal Jewish mother’ who sacrifices herself for her baby and is objectified as ‘food’, norms that were not commonly practiced by most Jewish Israeli families at the time.

Previous research indicates that the depletion of self-regulatory resources can promote unethical behavior that benefits the self. Extending this literature, we focus on norm-transgressing behavior that is intended to primarily benefit others. In particular, we predicted a differing effect of self-regulatory resource depletion on dishonesty that benefits one’s group, depending on the degree of identification with the group. Following a dual process approach, we argue that if identification with the group is strong, then people may have an automatic inclination to (...) benefit their group even perhaps by lying. In contrast, if identification with the group is weak, then the default, uncontrolled impulse may be to tell the truth. Accordingly, identification with the social group should interact with self-regulatory resource depletion in predicting group-benefiting dishonesty. Focusing on pro-organizational dishonesty, we tested our hypotheses in one field study with 1269 employees and in one experimental study with 71 university students. As predicted, the results revealed a highly significant interaction of organizational identification and self-control strength: Depletion of self-regulatory resources increased the level of pro-organizational dishonesty among those who identify highly with the organization, but decreased the level of such behavior among those who identify less.

Interaction between adults and infants by nature constitutes a strong powerasymmetry relationship. Based on the assumption that communicative practices with infants are inseparably intertwined with broader cultural ideologies of good child care, this paper will contrast how parents in two distinct socio-cultural communities deal with power asymmetry in interactions with 3-months old infants. The study consists of a microanalysis of videotaped free play mother-infant interactions from 20 middle class families in Muenster, Germany and 20 traditional farming Nso families in Kikaikelaki, (...) Cameroon. Analysis followed a discursive psychology approach. The focus of analysis is on how mothers handle and negotiate power-distance in these interactions and what discursive strategies they draw on. Mothers in both groups used various forms of directives and control strategies. The Muenster mothers, however, mainly used mitigated directives that can be seen as strategies to reduce the competence gap between mother and child, while the Nso mothers mainly used upgraded directives to stress the hierarchical discrepancy between mother and child. The different strategies are discussed in light of the prevailing broader cultural ideologies and the normative orientations that they reflect. Finally, the findings are discussed with regard to possible developmental consequences of these distinct cultural practices for the child. Keywords: power-asymmetry; mother-infant interaction; discursive psychology; culture; Nso farmers; Muenster middle class families. (shrink)

This article argues that attention and distraction form a central concern of Benjamin's writings on literature. Individually and in conjunction, they underpin processes of textual production and reception, yet their relationship is fluid and subject to historical change. In this respect, Benjamin's exploration of the interplay of attention and distraction in writers such as Leskov, Baudelaire and Brecht also leads to more general reflections about the social, cultural and psychological shifts brought about by industrialization and modern mass culture. Benjamin's writings (...) on literature trace developments which he also explores in relation to film. And echoes of his ‘literary history of attention’ can also be found in both his own critical approach and his self-reflexive comments on the process of writing. (shrink)

As Internet sources provide information of varying quality, it is an indispensable prerequisite skill to evaluate the relevance and credibility of online information. Based on the assumption that competent individuals can use different properties of information to assess its relevance and credibility, we developed the EVON, an interactive computer-based test for university students. The developed instrument consists of eight items that assess the skill to evaluate online information in six languages. Within a simulated search engine environment, students are requested to (...) select the most relevant and credible link for a respective task. To evaluate the developed instrument, we conducted two studies: a pre-study for quality assurance and observing the response process and a main study aimed at investigating the psychometric properties of the EVON and its relation to other variables. The results of the pre-study provided first evidence for a theoretically sound test construction with regard to students’ item processing behavior. The results of the main study showed acceptable psychometric outcomes for a standardized screening instrument with a small number of items. The item design criteria affected the item difficulty as intended, and students’ choice to visit a website had an impact on their task success. Furthermore, the probability of task success was positively predicted by general cognitive performance and reading skill. Although the results uncovered a few weaknesses, and the efforts of validating the interpretation of EVON outcomes still need to be continued, the overall results speak in favor of a successful test construction and provide first indication that the EVON assesses students’ skill in evaluating online information in search engine environments.

Recent reform initiatives calling for ‘civic’ professionalism can be seen as a response to the widely reported decline in public trust in the professions and an attempt to partially remedy this problem through a more publically engaged professionalism. The author draws on the political philosophy of Hannah Arendt, identifying the strong, albeit in the professionalism literature rarely acknowledged, affinities between civic professionalism and her concept of action as freedom through public deliberation. Using the three modalities of the active life that (...) Arendt discusses in The Human Condition as analytical tools, the author suggests that changing conditions in the public sector have led to professional life increasingly taking on the forms of labour and work, at the expense of action. The implications of these developments are highlighted before the author proceeds to show that a professional life oriented strongly towards action is consistent with ‘civic’ professionalism based on community engagement. Some of the main approaches traditionally taken to promote a civic orientation among university students are noted; the article concludes with a discussion of how the specific concepts underlying Arendtian action can be put to work in university pedagogies to intentionally promote the public ‘civic-minded professional’.

ObjectivePrevious research has shown reduced interoceptive accuracy in depression. Attention deficit represents a key symptom of depression. Moreover, IAcc is positively correlated with attention. There is no study that investigates the effect of depression on IAcc and attention. The aim of this study is to examine the mediating effect of IAcc on depression and attention.MethodsThirty-six depressed patients from the Psychosomatic Clinic in Windach were matched with 36 healthy controls according to age and sex and were assessed at Ulm University. All (...) participants completed the Beck Depression Inventory-II, the heartbeat perception task to examine IAcc, and the d2 test assessing selective attention.ResultsDepressed patients showed attention deficits—both for general visual attention and IAcc—compared to healthy controls. The mediation analyses revealed that the relationship between depression and attention is not mediated via IAcc. Furthermore, depression predicts IAcc and attention, but these effects are direct and largely unaffected by the respective other variable.DiscussionThe results of the present study highlight both interoceptive as well as attention deficits in depressed patients. No clear mediation between these variables could be shown in this study. More elaborative research is needed to clarify whether different approaches to improve IAcc are effective for these deficits in depressed patients and could therefore be of importance as an additional aspect of therapy in depression.

Since the nineteenth century, the debate around the process of professionalization of higher education has been characterized by two extreme positions. For some critics the process carries the risks of instrumentalizing knowledge and of leading the university to succumb under the demands of the market or the state; for other theorists it represents a concrete opportunity for the university to open up to the real needs of society and for reorienting theoretical and fragmented disciplines towards the resolution of concrete and (...) challenging problems. This article pursues three objectives. Firstly, we show that the debate is usefully informed not only by ideas of what a university is, but also by ideas of a profession. We suggest that both ideas help to overcome the conflict between the two afore-mentioned antagonist perspectives. Secondly, we demonstrate that a certain understanding of a profession can prevent the risk of viewing knowledge exclusively as scientific expertise and reducing training to the acquisition of technical skills. The position on professions adopted here is inspired by the Scottish philosopher Alasdair MacIntyre, whose work is instructive in understanding professions as “rational practical activities”, embedded in a social context with their own internal goods. Our third objective, therefore, is to argue, with MacIntyre, that the presence of professions within the university opens up the opportunity to rescue forms of rationality that are oriented towards action and, by implication, promotes spaces of training that are resistant to exclusively corporate or governmental interests and criteria of mere effectiveness.
