Lee and Schwarz interpret meta-analytic research and replication studies as providing evidence for the robustness of cleansing effects. We argue that the currently available evidence is unconvincing because publication bias and the opportunistic use of researcher degrees of freedom appear to have inflated meta-analytic effect size estimates, and preregistered replications failed to find any evidence of cleansing effects.

Gaisi Takeuti has recently proposed a new operation on orthomodular lattices L, ⫫: $\scr{P}\rightarrow L$ . The properties of ⫫ suggest that the value of ⫫ $$ corresponds to the degree in which the elements of A behave classically. To make this idea precise, we investigate the connection between structural properties of orthomodular lattices L and the existence of two-valued homomorphisms on L.

This article revisits the manuscript tradition and the different redactions of John Buridan’s commentaries on Aristotle’s Physics. The aim of the article is threefold. First, it makes some corrections to the lists of manuscripts containing the third redaction and the final redaction of Buridan’s questions commentary on the Physics. Second, it argues that manuscript Zaragoza, Biblioteca Capitular de la Seo, cod. 15-61, ff. 1r-62v, contains a previously unknown version of the final redaction (together with the standard version from f. 62v (...) onwards). Third, to facilitate further study of the manuscripts of Buridan’s questions on the Physics and their mutual relations, appendices at the end of the article provide detailed tables of contents for the third redaction and the final redaction, as well as editions of selected questions from the Zaragoza manuscript, the third redaction of Buridan’s questions on the Physics, and the so-called Quaestiones breves.

This essay attempts to develop a psychologically informed semantics of perception reports, whose predictions match with the linguistic data. As suggested by the quotation from Miller and Johnson-Laird, we take a hallmark of perception to be its fallible nature; the resulting semantics thus necessarily differs from situation semantics. On the psychological side, our main inspiration is Marr's (1982) theory of vision, which can easily accomodate fallible perception. In Marr's theory, vision is a multi-layered process. The different layers have filters of (...) different gradation, which makes vision at each of them approximate. On the logical side, our task is therefore twofold - to formalise the layers and the ways in which they may refine each other, and. (shrink)

Universities introduce intermediate assessment because it is understood to have positive effects on student behaviour and achievement. Yet, how intermediate assessment is perceived might be conditional for its success. The current study investigates both teachers’ and students’ perceptions of intermediate assessment. Teachers and students were interviewed and Student Evaluations of Teaching were examined. Results indicate that both teachers and students had generally positive perceptions of intermediate assessment. However, the two groups provided different reasons for their positive perceptions. Teachers and students (...) agreed that intermediate assessment helps students to keep up with their study work. Moreover, teachers mentioned that they could assess various knowledge and skills with intermediate assessment, whereas students preferred intermediate assessments to test the same knowledge and skills as the final exam. This finding suggests that teachers and students in our study had different goals... (shrink)

The high prevalence of cardiovascular diseases demands a reliable and sensitive risk assessment technique. In order to develop a fast and label-free immunosensor for C-reactive protein, a risk factor for this condition, anti-CRP antibodies were physically adsorbed to the hydrogen -terminated surface of nanocrystalline diamond. An Enzyme-Linked ImmunoSorbent Assay reference technique showed that this was a suitable substrate for antibody-antigen recognition reactions. Electrochemical Impedance Spectroscopy was used to electronically detect CRP recognition. The specificity of the immunosensor was demonstrated by incubation (...) with CRP and plasminogen as reference molecule. A different impedance behavior was observed in real-time after CRP addition as compared to plasminogen addition: the impedance increased only during CRP incubation. Fitting the data showed that this corresponded with a decrease in capacitance of the molecular layer due to its increased thickness by specific CRP recognition. Sensitivity experiments in real-time showed a clear discrimination between 1 μM, 100 nM, and 10 nM of CRP after 10 min at 100 Hz. Since, 10 nM of CRP was still clearly distinguishable from buffer solution, our CRP-directed immunosensor prototype reaches a sensitivity that is within the physiologically relevant concentration range of this biomarker in healthy controls and CVD patients. Moreover, this prototype displayed real-time discriminating power between spiked and unspiked serum, and thus also shows its applicability in this biological matrix. © 2011 Elsevier B.V.

The history of twentieth-century American psychology is often depicted as a history of the rise and fall of behaviorism. Although historians disagree about the theoretical and social factors that have contributed to the development of experimental psychology, there is widespread consensus about the growing and declining influence of behaviorism between approximately 1920 and 1970. Since such wide-scope claims about the development of American psychology are typically based on small and unrepresentative samples of historical data, however, the question rises to what (...) extent the received view is justified. This paper aims to answer this question in two ways. First, we use advanced scientometric tools to quantitatively analyze the metadata of 119.278 papers published in American journals between 1920 and 1970. We reconstruct the development and structure of American psychology using co-citation and co-occurrence networks and argue that the standard story needs reappraising. Second, we argue that the question whether behaviorism was the ‘dominant’ school of American psychology is historically misleading to begin with. Using the results of our bibliometric analyses, we argue that questions about the development of American psychology deserve more fine-grained answers. (shrink)

Multi-stakeholder initiatives claim to make production of commodities more socially and environmentally sustainable by regulating their members and through systems of certification. These claims, however, are highly contested. In this article, I examine how actors use MSI regulation with regard to land conflicts with a focus on the Roundtable on Sustainable Palm Oil. MSIs are a resource that actors in land conflicts can use to generate evidence that gives them leverage in their negotiations. To do so, actors employ the interrelations (...) between two kinds of land conflict: localized land conflicts between local land users, and disputes between more distant actors over aggregated land-use related to the sustainability of palm oil production. To demonstrate this, I use the notion of assemblage in two case studies from Sumatra, Indonesia. Thinking in terms of assemblage allows the contradictory but interrelated practices that shape MSIs to be understood. In distinct locally embedded processes, actors enact MSIs in contexts of unequal power relations, from which MSI governance emerges. The way in which access to an MSI is distributed among contending actors shapes MSI enactments and thus its governance. The unequal distribution of access to the RSPO results in a governance that favors companies over communities. (shrink)

It has been hypothesized that illusory agency detection is at the basis of belief in supernatural agents and paranormal beliefs. In the present study a biological motion perception task was used to study illusory agency detection in a group of skeptics and a group of paranormal believers. Participants were required to detect the presence or absence of a human agent in a point-light display. It was found that paranormal believers had a lower perceptual sensitivity than skeptics, which was due to (...) a response bias to ‘yes’ for stimuli in which no agent was present. The relation between paranormal beliefs and illusory agency detection held only for stimuli with low to intermediate ambiguity, but for stimuli with a high number of visual distractors responses of believers and skeptics were at the same level. Furthermore, it was found that illusory agency detection was unrelated to traditional religious belief and belief in witchcraft, whereas paranormal beliefs were strongly related to illusory agency detection. These findings qualify the relation between illusory pattern perception and supernatural and paranormal beliefs and suggest that paranormal beliefs are strongly related to agency detection biases.

The starting point of the present paper is Bell’s notion of local causality and his own sharpening of it so as to provide for mathematical formalisation. Starting with Norsen’s analysis of this formalisation, it is subjected to a critique that reveals two crucial aspects that have so far not been properly taken into account. These are the correct understanding of the notions of sufficiency, completeness and redundancy involved; and the fact that the apparatus settings and measurement outcomes have very different (...) theoretical roles in the candidate theories under study. Both aspects are not adequately incorporated in the standard formalisation, and we will therefore do so. The upshot of our analysis is a more detailed, sharp and clean mathematical expression of the condition of local causality. A preliminary analysis of the repercussions of our proposal shows that it is able to locate exactly where and how the notions of locality and causality are involved in formalising Bell’s condition of local causality.

In this contribution, I discuss some less well-known premodern and early modern antecedents of Spinoza’s concepts and claims in the _Tractatus Theologico-Politicus_. On the one hand, I will argue, Spinoza’s notion of prophecy owes more to Moses Maimonides than to any Christian author; and through Maimonides, Spinoza may be linked to the discussion of prophecy in _The Virtuous City_ by the tenth-century Islamic philosopher al-Farabî. Spinoza’s concern with prophecy as a popular formulation of the Divine Law may be fruitfully seen (...) in the light of these two authors. On the other hand, Spinoza’s notion of _pietas_ has arguably been shaped by a number of early modern authors from the Low Countries, including Thomas a Kempis and Erasmus: it does not consist in merely obeying the law, but also has a clear devotional and theist dimension of love for God and for one’s neighbors. As such, it may be associated with recent ideas on philosophy and spiritual exercises. These findings have a number of non-trivial implications for Spinoza’s place in the rise of modern, academic Western philosophy. I will discuss these implications in the context of Pierre Hadot’s influential views on philosophy as a way of life and Michel Foucault’s notion of spirituality. (shrink)

AbstractWhile the literature on oncofertility decision-making was central to the bioethics debate on social egg freezing when the practice emerged in the late 2000s, there has been little discussion juxtaposing the two forms of egg freezing since. This article offers a new perspective on this debate by comparing empirical qualitative data of two previously conducted studies on medical and social egg freezing. We re-analysed the interview data of the two studies and did a thematic analysis combined with interdisciplinary collaborative auditing (...) for empirical ethics projects. Despite their different contexts, major similarities in women’s decision-making and reasoning were found. We developed two main common themes. Firstly, women felt a clear need to plan for future options. Secondly, they manipulated decision-times by postponing definitive decisions and making micro-decisions. The comparison highlights that the passage of time and the preservation of future choice seems to permeate all aspects of the patient experiences in both studies. As a result of considering real-world lived experiences, we suggest that there are many overlaps in women’s reasoning about egg freezing regardless of why they are making a decision to freeze. These overlaps are morally relevant and thus need to be further integrated into the existing arguments that have been canvassed in the flourishing egg freezing and fertility preservation debates across the field, and in policy and practice globally.

What makes video games unique as an audiovisual medium is not just that they are interactive, but that this interactivity is rule bound and goal oriented. This means that player experience, including experience of the music, is somehow shaped or structured by these characteristics. Because of its emphasis on action in perception, James Gibson’s ecological approach to psychology—particularly his concept of affordances—is well suited to theorise the role of music in player experience. In a game, players perceive the environment and (...) gameplay situations in terms of the goal-oriented actions they afford. Nondiegetic music, not tied to any place in the digital game world, can play a unique role in the structuring of these affordances. Through a series of case studies, I will show that music creates and structures situations both in the game environment (such as the appearance of enemies in Unreal) and beyond the game environment (such as the death of an avatar and the restart of a level in Super Mario Bros.).

The Natural Problems, attributed to Aristotle, have gained much scholarly attention in the last decades, yet a systematic study of how the collection circulated in the Graeco-Roman Empire remains a blind spot in contemporary scholarship. Indeed, the Imperial Era is a seminal period for the history of the text, not just as a conduit between Aristotle and the Middle Ages – which in itself is essential for explaining the subsequent Arabic and Latin uptake of the Problems more clearly – but (...) also for the wealth of sources and testimonies it offers about the collection’s ancient readership and concrete use. The evidence shows that the collection sparked much debate among a range of ancient philosophers, doctors, sophists and scholars, both Greeks and Romans. This paper provides a selection of readings representative of the different socio-intellectual milieus in which the Problems circulated and the different agendas that it served. (shrink)

This study presents an approach to metaphor that systematically takes contextual factors into account. It analyses how metaphors both depend on, and change, the context in which they are uttered, and specifically, how metaphorical interpretation involves the articulation of asserted, implied and presupposed material. It supplements this semantic analysis with a practice-based account of metaphor at the conceptual level, which stresses the role of sociocultural factors in concept formation.

Contemporary philosophy of moral motivation has much to say about the nature of moral beliefs and truths, but it has less to say about emancipation. By neglecting to discuss the emancipatory aspect of motivation, I argue, moral epistemology is neglecting a topic that should be central. Starting from Charles Taylor’s concern for the status of moral sources, the paper’s main points are that moral motivation has a distinctive emancipatory dimension which has been largely neglected in mainstream debates; that the issue (...) of emancipation can only be adequately conceptualized at the intersection of normative ethics and metaethics; that a full-blooded account of motivation must incorporate a phenomenology of motivational experience, which in turn requires extending the concept of motivation beyond a narrow definition to include such notions as meaning, articulation, identity, and freedom, and criticizing conceptions of motivation that are blind to or take for granted the quality of motivation; and thus providing the resources for a thick conception of motivation that breaks new ground by overcoming the existing boundaries between normative ethics and metaethics.

The value of Plutarch’s perception of physical reality and his attitude towards the natural spectacle Plutarch was very interested in the natural world around him, not only in terms of its elementary composition and physical processes, but also with respect to its providential ordering and marvels. His writings teach us a lot about his perception of physical reality and about his attitude to the natural spectacle. He found his greatest inspiration in the ontological and epistemological framework of Plato’s Timaeus, but (...) a wide range of other authors were also of seminal interest to his project. Moreover, the highly literary value of Plutarch’s natural philosophical writings should not be underrated. It is therefore not surprising that recently scholars have started to reassess the ancient scientific value of Plutarch’s natural philosophical writings. Natural Spectaculars aims to give further impetus to this dynamic by treating several aspects of Plutarch’s natural philosophy which have remained unexplored up to now. (shrink)

This study examined whether stimulation of immigrant and national pupils’ use of high‐quality helping behaviour during cooperative learning in classrooms boosts their maths‐related talk more than in an educational situation in which such stimulation is largely absent . A total of 59 elementary‐age pupils enrolled in a CL maths curriculum of 11 lessons. They were video taped during two lessons while working together on maths assignments to assess their maths‐related talk. We found that the quality of maths‐related talk was higher (...) in the experimental condition. Furthermore, immigrant pupils’ used less maths‐related talk than the national pupils. Implications are discussed. (shrink)

This interview with Charles Taylor explores a central concern throughout his work, namely, his concern to ‘reenchant’ self and world through a careful examination of value as emanating from the world rather than from ourselves. It focuses especially on the status of his central doctrine of ‘strong evaluation’ against the background of mainstream meta-ethical theories, such as neo-Kantian constructivism and robust realist non-naturalism. Additionally, the relationship between Taylor’s theism and his moral–political philosophy is discussed. A key issue that is examined (...) is what ontological background picture can make sense of the strong evaluative experience of higher worth. Some other related issues that are explored revolve around Taylor’s papers ‘Disenchantment-Reenchantment’ and ‘Recovering the Sacred’, which tentatively explore the meaning of reenchantment.

This paper explores the relation between metaethical reflection and value experience, and does so by focusing on robust realism. Robust realism is typically criticized for its ontological and epistemological commitments. In this paper, however, we hope to shed new critical light on the plausibility of the theory by using two concepts – ‘reification’ and ‘alienation’ – that have their origin in critical social theory. We use the concept of ‘reification’ as an interpretative lens to look at robust realism and show (...) that it is reifying in two respects: it turns values into things, and, correspondingly, turns human agents into disengaged observers of those things. This analysis is then used to argue that robust realism is alienating in the sense that it distances us from the world that presents itself to us in value experience, and that it separates us from what we call our engaged responsiveness. We also argue that its alienating effects give us good reason to reject the theory. (shrink)

This book provides a comprehensive critical account of Taylor’s writings, and argues that a close examination of his central concept of “strong evaluation” reveals both the potential of and the tensions in his entire thinking.

BackgroundIn many countries health insurers, employers and especially governments are increasingly using pressure and coercion to enhance healthier lifestyles. For example by ever higher taxes on cigarettes and alcoholic beverages, and ever stricter smoke-free policies. Such interventions can enhance healthier behaviour, but when they become too intrusive, an unfree society can emerge. Which lifestyle interventions that use pressure or coercion are justifiable and which are not? We tried to develop an assessment model that can be used for answering this question, (...) on a generally acceptable way, for all sorts of lifestyle interventions.MethodsThe intended assessment model was developed in three phases. In the first phase the model was theoretically developed on the basis of literature study and reasoning. In the second phase the model was empirically tested by assessing two detailed cases from everyday practice using the model. The model was improved again and again. In the third phase the 10th version of the model was developed while writing this article.ResultsAn assessment model for the justification of intrusive lifestyle interventions. It comprises three components: 12 assessment criteria ; an assessment structure with three filters ; a way of assessing.ConclusionsWe have developed an assessment model for the justification of lifestyle interventions that use pressure or coercion to promote health. The correctness, completeness and practicality of the model are likely. Important principles for the justification are the logic and completeness of the underlying argumentation and the proper use of the available scientific information. Parties for and against a particular intervention could use the model to test and strengthen their argumentation and to improve the quality of the intervention. (shrink)

This article analyzes Drucilla Cornell’s critical theory as a practice of engaging with radical thinking and radical politics in the interest of revolutionary transformation. Arguing that Walter Benjamin’s imperative to wrest tradition away from conformism is at the heart of Cornell’s work, the article shows how Cornell applies this imperative both to the tradition of resistance against oppression and to critical theory itself. The article follows Cornell’s call to decolonize the critical theoretical project by bringing Surinamese anticolonial activist and writer (...) Anton de Kom, various collectives that participated in the 2022 German art festival documenta 15, and the disobedience of six young Palestinian “Freedom Riders” into conversation with Cornell’s writings on the South African Revolution and on Afro-Caribbean liberatory thought.

Although Kant (1998) envisaged a prominent role for logic in the argumentative structure of his Critique of Pure Reason, logicians and philosophers have generally judged Kantgeneralformaltranscendental logics is a logic in the strict formal sense, albeit with a semantics and a definition of validity that are vastly more complex than that of first-order logic. The main technical application of the formalism developed here is a formal proof that Kants logic is after all a distinguished subsystem of first-order logic, namely what (...) is known as geometric logic.

In this editorial contribution, two issues relevant to the question, what should be at the top of the research agenda for ethics and technology, are identified and discussed. Firstly: can, and do, engineers make a difference to the degree to which technology leads to morally desirable outcomes? What role does professional autonomy play here, and what are its limits? And secondly, what should be the scope of engineers’ responsibility; that is to say, on which issues are they, as engineers, morally (...) obliged to reflect? The research agendas proposed by the authors contributing to this special section, implicitly, give different answers to these questions. We suggest that an explicit discussion of these issues would greatly help in constructing a common research agenda. (shrink)
