A new approach to quantum theory is proposed in this paper. The basis is taken to be theoretical variables, variables that may be accessible or inaccessible, i.e., it may be possible or impossible for an observer to assign arbitrarily sharp numerical values to them. In an epistemic process, the accessible variables are just ideal observations connected to an observer or to some communicating observers. Group actions are defined on these variables, and group representation theory is the basis for developing the (...) Hilbert space formalism here. Operators corresponding to accessible theoretical variables are derived, and in the discrete case, it is proved that the possible physical values are the eigenvalues of these operators. The focus of the paper is some mathematical theorems paving the ground for the proposed foundation of quantum theory. It is shown here that the groups and transformations needed in this approach can be constructed explicitly in the case where the accessible variables are finite-dimensional. This simplifies the theory considerably: To reproduce the Hilbert space formulation, it is enough to assume the existence of two complementary variables. The interpretation inferred from the proposed foundation here may be called a general epistemic interpretation of quantum theory. A special case of this interpretation is QBism; it also has a relationship to several other interpretations. (shrink)

"This book is interesting and well-written. The research methods were explained clearly and conclusions were summarized nicely. It is a relatively quick read at only 130 pages. Anyone who has been told, or who has told others, that mathematicians make better thinkers should read this book." MAA Reviews "The authors particularly attend to protecting positive correlations against the self-selection interpretation, merely that logical minds elect studying more mathematics. Here, one finds a stimulating survey of the systemic difficulties people have with (...) basic syllogisms and deductions." CHOICE connect "The authors particularly attend to protecting positive correlations against the self-selection interpretation, merely that logical minds elect studying more mathematics. Here, one finds a stimulating survey of the systemic difficulties people have with basic syllogisms and deductions." CHOICE Connect For centuries, educational policymakers have believed that studying mathematics is important, in part because it develops general thinking skills that are useful throughout life. This 'Theory of Formal Discipline' (TFD) has been used as a justification for mathematics education globally. Despite this, few empirical studies have directly investigated the issue, and those which have showed mixed results. Does Mathematical Study Develop Logical Thinking? describes a rigorous investigation of the TFD. It reviews the theory's history and prior research on the topic, followed by reports on a series of recent empirical studies. It argues that, contrary to the position held by sceptics, advanced mathematical study does develop certain general thinking skills, however these are much more restricted than those typically claimed by TFD proponents. Perfect for students, researchers and policymakers in education, further education and mathematics, this book provides much needed insight into the theory and practice of the foundations of modern educational policy.

The Durkheim Test. Remarks on Susan Leigh Star’s Boundary Objects. The article reconstructs Susan Leigh Star’s conceptual work on the notion of ‘boundary objects’. It traces the emergence of the concept, beginning with her PhD thesis and its publication as Regions of the Mind in 1989. ‘Boundary objects’ attempt to represent the distributed, multifold nature of scientific work and its mediations between different ‘social worlds’. Being addressed to several ‘communities of practice’, the term responded to questions from Distributed Artificial Intelligence (...) in Computer Science, Workplace Studies and Computer Supported Cooperative Work (CSCW), and microhistorical approaches inside the growing Science and Technology Studies. Yet the interdisciplinary character and interpretive flexibility of Star’s invention has rarely been noticed as a conceptual tool for media theory. I therefore propose to reconsider Star’s ‘Durkheim test’ for sociotechnical media practices. (shrink)

Social theory is a crucial resource for the social sciences. It provides rich insights into how human beings think and act and how contemporary social life is constructed. But often the key ideas of social theorists are expressed in highly technical and difficult language that can hide more than it reveals. The new edition of this popular book continues to cut to the core of what social theory is about. Covering key themes from the classical thinkers onwards, including Marxism, post-structuralism, (...) phenomenology, feminism and more, the second edition features a new chapter on Actor-Network Theory and enhanced discussion of postcolonial theory. Wide ranging in scope and coverage, the book is concise in presentation and free from jargon. Showing why social theory matters, and why it is of far-reaching social and political importance, the book is ideal for readers seeking a clear, crisp mapping of a complex but very rewarding area.

Ending the influence which politicalparties exercised over judicial appointmentswas a prominent aim of the project of reformingthe Belgian criminal justice system in the1990s. However, focusing on various highprofile scandals affecting public confidence inthe judiciary, this paper questions whether thepolitical nature of the judiciary is capable ofbeing eradicated. Drawing on the work ofChantal Mouffe, this analysis starts with aconsideration of the discursive element inpolitical identity, which is furthercorroborated by the semiotics of Saussure andGreimas. Applying this perspective to theBelgian situation in the (...) 1990s, it is arguedthat a redefinition of politics in terms of an``us/them'' divide between citizens andinstitutions took place. In this process,judges were targeted as part of theestablishment and cast as the constitutiveoutside buttressing the collectiveidentification between the media, victims ofcrime and the general public. In explaining theinstitutional gap, individual traits of judgesconstituted a significant focus, as can beshown through the extraordinary visibility ofone judge who courted media attention when hewas tried for sadomasochistic activities in1997.

Zusammenfassung Insbesondere im Alter prägen Determinanten sozialer Ungleichheit das sportliche Handeln sowie die körperliche Verfassung und somit das korporale Kapital von Individuen. Von wesentlicher Bedeutung sind dabei die vertikalen Determinanten sozialer Ungleichheit wie kulturelles, soziales und ökonomisches Kapital. Ziel der Studie war es, direkte und indirekte Beziehungen zwischen den Kapitalarten und sportlichem Handeln zu untersuchen. Die Zusammenhänge wurden auf Basis einer Befragung von N = 320 Personen mittels eines Mediationsmodells überprüft. Der Zusammenhang zwischen dem kulturellen und dem korporalen Kapital wurde (...) darin vollständig durch das soziale Kapital und die Sportaktivität vermittelt. Implikationen für die Rolle des sozialen Kapitals in der Entstehung von sozialer Ungleichheit werden diskutiert. (shrink)

This book is about disobedience. Positive disobedience. Disobedience as a kind of professional behaviour. It shows how teachers can survive and even influence an education system that does staggering damage to potential. More importantly it is an arm around the shoulder of disobedient teachers who transform people's lives, not by climbing promotion ladders but by operating at the grassroots.Disobedient Teaching tells stories from the chalk face. Some are funny and some are heartbreaking, but they all happen in New Zealand schools.This (...) book says you can reform things in a system that has become obsessed with assessment and tick-box reporting. It shows how the essence of what makes a great teacher is the ability to change educational practices that have been shaped by anxiety, ritual and convention. Disobedient Teaching argues the transformative power of teachers who think and act. (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)

The struggle to create and sustain meaning in our everyday lives is fought using cultural ingredients to spin the webs of meaning that keep us going. To help reveal the complexity and intricacy of the webs of meaning in which they are suspended, Tom Inglis interviewed one-hundred people in their native home of Ireland to discover what was most important and meaningful for them in their lives. Inglis believes language is a medium: there is never an exact correspondence between what (...) is said and what is felt and understood. Using a variety of theoretical lenses developed within sociology and anthropology, Inglis places their lives within the context of Ireland's social and cultural transformations, and of longer-term processes of change such as increased globalisation, individualisation, and informalisation.

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)

In this paper, we argue that several recent ‘wide’ perspectives on cognition (embodied, embedded, extended, enactive, and distributed) are only partially relevant to the study of cognition. While these wide accounts override traditional methodological individualism, the study of cognition has already progressed beyond these proposed perspectives towards building integrated explanations of the mechanisms involved, including not only internal submechanisms but also interactions with others, groups, cognitive artifacts, and their environment. The claim is substantiated with reference to recent developments in the (...) study of “mindreading” and debates on emotions. We claim that the current practice in cognitive (neuro)science has undergone, in effect, a silent mechanistic revolution, and has turned from initial binary oppositions and abstract proposals towards the integration of wide perspectives with the rest of the cognitive (neuro)sciences.

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.

Aquinas is often presented as following Aristotle's "Nicomachean Ethics" when treating moral virtue. Less often do philosophers consider that Aquinas's conception of the highest good and its relation to the functional character of human activity led him to break with Aristotle by replicating each of the acquired moral virtues on an infused level. The author suggests that we can discern reasons for this move by examining Aquinas's commentary on the "Sententiae" of Peter the Lombard and the "Summa theologiae" within their (...) historical context. The author's thesis is that Dominican pastoral and intellectual concerns led Aquinas to argue that moral virtue must necessarily be ordered toward the highest good. Understanding this purpose helps to explain his presentation of moral virtue and its implications for standard philosophical interpretations of his work. (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.

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)

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)

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)

According to a U.S. court ruling, intelligent design (ID) theory is religious in nature, not scientific, and must not be taught in schools. In opposition, Fuller argues for a closer rapport between science and religion. Here it is emphasized that any allegedly scientific conclusion from design in nature to the existence of God is a hypothesis subject to the same quality norms as empirical hypotheses in general. By quotations from his Iter Lapponicum , Linnæus is summoned in support of a (...) strictly immanent conception of science, against Fuller’s suggestion that Linnæus’ personal piety could be a reason for considering ID scientific.
