Iterated conditionals of the form If p, then if q, r are an important topic in philosophical logic. In recent years, psychologists have gained much knowledge about how people understand simple conditionals, but there are virtually no published psychological studies of iterated conditionals. This paper presents experimental evidence from a study comparing the iterated form, If p, then if q, r with the “imported,” noniterated form, If p and q, then r, using a probability evaluation task and a truth-table task, (...) and taking into account qualitative individual differences. This allows us to critically contrast philosophical and psychological approaches that make diverging predictions regarding the interpretation of these forms. The results strongly support the probabilistic Adams conditional and the “new paradigm” that takes this conditional as a starting point. (shrink)
The legitimacy of the dominant intensive meat production system with respect to the issue of animal welfare is increasingly being questioned by stakeholders across the meat supply chain. The current meat supply is highly undifferentiated, catering only for the extremes of morality concerns (i.e., conventional vs. organic meat products). However, a latent need for compromise products has been identified. That is, consumer differences exist regarding the trade-offs they make between different aspects associated with meat consumption. The heterogeneity in consumer demand (...) could function as a starting point for market segmentation, targeting and positioning regarding animal welfare concepts that are differentiated in terms of animal welfare and price levels. Despite this, stakeholders in the meat supply chain seem to be trapped in the dominant business model focused on low cost prices. This paper aims to identify conflicting interests that stakeholders in the meat supply chain experience in order to increase understanding of why heterogeneous consumer preferences are not met by a more differentiated supply of meat products produced at different levels of animal welfare standards. In addition, characteristics of the supply chain that contribute to the existence of high exit barriers and difficulty to shift to more animal-friendly production systems are identified. Following the analysis of conflicting interests among stakeholders and factors that contribute to difficulty to transform the existing dominant regime, different routes are discussed that may help and motivate stakeholders to overcome these barriers and stimulate the creation of new markets.

Classroom discussion is frequently proposes as an essential part of democratic citizenship education. Literature, however, pays little attention to what kind of discussion is most effective and how teachers can facilitate a discussion. This study aims to contribute to the development of a framework for analysing the characteristics of classroom discussions and the different roles teachers can adopt in guiding a discussion on controversial issues. In addition, we investigated how the way teachers guide the discussion is related to the structure (...) and content features of the discussion. The framework was used to analyse five classroom discussions in secondary education. Our framework appeared to be useful for revealing differences in the structure and content features of the classroom discussions and in the way teachers guide the discussion. The results also indicated that a high degree of teacher regulation was related to high content quality and more participation from students. A high degree of stu... (shrink)
The traditional use of ergodic theory in the foundations of equilibrium statistical mechanics is that it provides a link between thermodynamic observables and microcanonical probabilities. First of all, the ergodic theorem demonstrates the equality of microcanonical phase averages and infinite time averages (albeit for a special class of systems, and up to a measure zero set of exceptions). Secondly, one argues that actual measurements of thermodynamic quantities yield time averaged quantities, since measurements take a long time. The combination of these (...) two points is held to be an explanation why calculating microcanonical phase averages is a successful algorithm for predicting the values of thermodynamic observables. It is also well-known that this account is problematic.
This survey intends to show that ergodic theory nevertheless may have important roles to play, and it explores three other uses of ergodic theory. Particular attention is paid, firstly, to the relevance of specific interpretations of probability, and secondly, to the way in which the concern with systems in thermal equilibrium is translated into probabilistic language. With respect to the latter point, it is argued that equilibrium should not be represented as a stationary probability distribution as is standardly done; instead, a weaker definition is presented.

In the usual procedure of deriving equilibrium thermodynamics from classical statistical mechanics, Gibbsian fine-grained entropy is taken as the analogue of thermodynamical entropy. However, it is well known that the fine-grained entropy remains constant under the Hamiltonian flow. In this paper it is argued that we need not search for alternatives for fine-grained entropy, nor do we have to reject Hamiltonian dynamics, in order to solve the problem of the constancy of fine-grained entropy and, more generally, to account for the (...) non-equilibrium part of the laws of thermodynamics. Rather, we have to weaken the requirement that equilibrium be identified with a stationary probability distribution. (shrink)
The participation of vulnerable patients in clinical research poses apparent ethical dilemmas. Depending on the nature of the vulnerability, their participation may challenge the ethical principles of autonomy, non-maleficence, or justice. On the other hand, non-participation may preclude the building of a knowledge base that is a prerequisite for defining the optimal clinical management of vulnerable patients. Such clinical uncertainty may also incur substantial economic costs. We present the participation of pre-menopausal women with atrial fibrillation in trials of novel oral (...) anticoagulant drugs as a case study. Due to their non-participation in pivotal trials, it is uncertain whether for them, the risks that are associated with these drugs are outweighed by the advantages compared with conventional treatment. We addressed the question whether research of this new class of drugs in this subgroup would be appropriate from both, an ethical as well an economic perspective. We used the method of specifying norms as a wider framework to resolve the apparent ethical dilemma, while incorporating the question whether research of oral anticoagulants in premenopausal women with atrial fibrillation can be justified on economic grounds. For the latter, the results of a value-of-information analysis were used. Further clinical research on NOACs in premenopausal women with atrial fibrillation can be justified on both, ethical and economic grounds. Addressing apparent ethical dilemmas by invoking a method such as specifying norms can improve the quality of public practical reasoning. As such, the method should also prove valuable to committees that have formally been granted the authority to review trial protocols and proposals for scientific research. (shrink)
Dialogic Teaching is effective in fostering student learning; yet, it is hard to implement. Little research focused on secondary teachers’ learning of DT and on the link between teachers’ understanding and practices, although these two are usually strongly intertwined. Using a wide range of evidence, this case study systematically investigated and compared two secondary teachers’ understanding and practice of DT during their participation in a continuing professional development programme. The CPDP appeared effective to some extent. The History teacher’s understanding of (...) DT, i.e. being a co-learner, appeared highly effective in implementing DT, whereas the Mathematics teacher’s understanding of DT, i.e. creating a democratic learning environment, seemed only effective to some extent. Focusing on both teachers’ understanding and practice when developing DT seemed fruitful in explaining differences in practice. Future research could further explore to what extent understanding DT as being a co-learner facilitates professional development. (shrink)
Using Althaus-Reid’s Indecent Theology as a methodology, this article contributes to reflections on the contextuality and physical dimension of Dutch theology: its relation to the Protestant white bodies of its practitioners and its support of and contributions to colonial power and colonial racializing discourse. We do this in a context of a ‘return to decency’ in political discourse in which ‘our’ Calvinist roots are evoked to construct a ‘shared’ past. Using two case studies, we analyse how the in/decent is constructed (...) in the Netherlands. As secularism is more ‘vanilla’ and Calvinism more indecent than is usually assumed, engagement with indecent texts and untidy roots of Calvinism is needed to re-member both the violent character of Calvinist hermeneutics, as well as its potential for indecent readings.

Bohr and Heisenberg suggested that the thermodynamical quantities of temperature and energy are complementary in the same way as position and momentum in quantum mechanics. Roughly speaking their idea was that a definite temperature can be attributed to a system only if it is submerged in a heat bath, in which case energy fluctuations are unavoidable. On the other hand, a definite energy can be assigned only to systems in thermal isolation, thus excluding the simultaneous determination of its temperature. Rosenfeld (...) extended this analogy with quantum mechanics and obtained a quantitative uncertainty relation in the form ΔU Δ(1/T) ≥ k, where k is Boltzmann's constant. The two “extreme” cases of this relation would then characterize this complementarity between isolation (U definite) and contact with a heat bath (T definite). Other formulations of the thermodynamical uncertainty relations were proposed by Mandelbrot (1956, 1989), Lindhard (1986), and Lavenda (1987, 1991). This work, however, has not led to a consensus in the literature. It is shown here that the uncertainty relation for temperature and energy in the version of Mandelbrot is indeed exactly analogous to modern formulations of the quantum mechanical uncertainty relations. However, his relation holds only for the canonical distribution, describing a system in contact with a heat bath. There is, therefore, no complementarily between this situation and a thermally isolated system. (shrink)
The Middle Ages saw a great flourishing of philosophy. Now, to help students and researchers make sense of the gargantuan—and, often, dauntingly complex—body of literature on the main traditions of thinking that stem from the Greek heritage of late antiquity, this new four-volume collection is the latest addition to Routledge’s acclaimed Critical Concepts in Philosophy series. Christina Van Dyke of Calvin College, USA, and an editor of the Cambridge History of Medieval Philosophy, has carefully assembled classic contributions, as well as (...) more recent work, to create a one-stop ‘mini library’ of the best and most influential scholarship. -/- With a comprehensive index and a useful synoptic introduction newly written by the editor, Medieval Philosophy will be welcomed as an indispensable resource for reference and research.

NG van Kampen is a well-known theoretical physicist who has had a long and distinguished career. His research covers scattering theory, plasma physics, statistical mechanics, and various mathematical aspects of physics. In addition to his scientific work, he has written a number of papers about more general aspects of science. An indefatigable fighter for intellectual honesty and clarity, he has pointed out repeatedly that the fundamental ideas of physics have been needlessly obscured. As those papers appeared in various journals, partly (...) in Dutch, it was felt that it would be worthwhile to collect them and make them available to a larger audience. This is a book of major importance to scientists and university teachers. (shrink)

On the basis of a contingency approach hypotheses are formulated with regard to this question. These hypotheses are confronted with the field of Dutch municipal policies for marginal adolescents.This study intends to point out:- that a diagnosis-modelfor designing a policy is appropriate to tackle complex and certain problems;- (...) that a learning-model for designing a policy is appropriate to tackle complex and uncertain problems;- that a fitting policy theory is a necessary, but insufficient condition for an effective policy;- that a lack ofconsensus in the political! environment of the process of designing a policy has a negative effect on the goal attainment, if the opponents of the policy have the power to obstruct the process of implementation;- that a lack professional qualities of implementers has a negative effect on the goal attainment.

Psillos has recently argued that van Fraassen’s arguments against abduction fail. Moreover, he claimed that, if successful, these arguments would equally undermine van Fraassen’s own constructive empiricism, for, Psillos thinks, it is only by appeal to abduction that constructive empiricism can be saved from issuing in a bald scepticism. We show that Psillos’ criticisms are misguided, and that they are mostly based on misinterpretations of van Fraassen’s arguments. Furthermore, we argue that Psillos’ arguments for his claim that constructive empiricism itself (...) needs abduction point up to his failure to recognize the importance of van Fraassen’s broader epistemology for constructive empiricism. Towards the end of our paper we discuss the suspected relationship between constructive empiricism and scepticism in the light of this broader epistemology, and from a somewhat more general perspective.

We analyse whether Belgian tax policy over the period 1965-1995 was affected by the ideological position of the government. Both the level and composition of taxation are considered. We find no significant ideological effect on the level of the tax burden. The burden has increased systematically over most of the period, irrespective of the ideology of the incumbent. Considering individual tax categories, one can find a significant ideological influence for taxes on financial and capital transactions. Under centre-left oriented governments this (...) tax is lowered whereas it increases under centre-right governments. A possible explanation is that centre-left governments try to stimulate households' wealth acquisition by keeping taxes on transactions of immovable properties low. (shrink)
What is empiricism and what could it be? Bas C. van Fraassen, one of the world's foremost contributors to philosophical logic and the philosophy of science, here undertakes a fresh consideration of these questions and offers a program for renewal of the empiricist tradition. The empiricist tradition is not and could not be defined by common doctrines but embodies a certain stance in philosophy, van Fraassen says. This stance is displayed first of all in a searing recurrent critique of metaphysics, (...) and second in a focus on experience that requires a voluntarist view of belief and opinion. (shrink)

The Christian-democrat/socialist government Martens IV resigned at the end ofMarch 1981, because the socialist party could not agree with an urgency plan to reorganize the public finances. Mark Eyskens, Minister of Finance in that cabinet, put together a new government as soon as April 6 of the same year. He succeeded as Prime Minister while all the other resigning ministers remained in their function. Minister Robert Vandeputte, an extra-parlementarian and honorary governor of the Central Bank, became the new Minister of (...) Finance. Like the preceding governments, the Eyskens cabinet was strongly hampered by deep mistrust between the coalition partners, opposing views between the two communities of Belgium and by disagreements about the way to deal with the socio-economic crisis.The Eyskens cabinet was particularly confronted with the organization of the restructured steelmill Cockerill-Sambre and with the absolute low point of the economic crisis. The budget was strongly affected by the increasing unemployment benefits and the collapse of the fiscal revenues. Due to the continuing protest of the trade unions, Mark Eyskens did not succeed to adapt the automatic wage indexation in order to improve the competitive position ofthe Belgian enterprises. He did however manage to prevent the devaluation of the Belgian franc, which had come under pressure regularly on the financial markets.By the middle of September 1981 the Eyskens government fell as a result of disagreements between the coalition partners about the financing ofthe money loosing steelmill Cockerill-Sambre in Wallonia. Parliamentary elections were advanced to November 8, 1981. The Christiandemocrats lost a considerable number of seats. A Christian-democrat/liberal cabinet, again headed by Wilfried Martens, emerged by mid December. It would carry out a neoliberal policy. Mark Eyskens became the Minister of Economicaffairs in the new government. (shrink)
While Christian Democratic parties in several Western European countries are often said to be in crisis, the European People's Party holds the largest parliamentary group in the European Parliament since 1999. This paradox relies on the specificity of the different 'national' electoral logics on the one hand and the realisation of a long-term 'European' majority strategy on the other hand. The alliance with Conservatives and Conservative parties has to overcome an absolute electoral decline in 'old' EU countries and a relative (...) decline through the accession of 'new' member states without Christian Democratic parties. The EPP majority strategy is realised through various ways : the key position of the transnational party and party group, the role of political leadership, the way of decision making, the co-operation with side-organisations, the problem-solving of ideological conflicts, etc. Our analysis proves how the majority strategy of the European Christian Democrats realises its ultimate 'survival strategy' despite several nationalparty crises.

The thesis developed and defended in this paper is that is it false that all knowledge is founded on experience. Much of our knowledge (or alleged knowledge), it is argued, is based on testimony. Still, many philosophers have either not dealt with testimony at all, or treated it very unkindly. One of the reasons for this is that those philosophers (such as Descartes and Locke) work with a concept of knowledge according to which knowledge is certain, indubitable, and/or self-evident. And (...) if knowledge is what these philosophers say it is, then there is no such thing as knowledge based on testimony indeed. Thomas Reid is introduced as holding that we do have testimonial knowledge and that therefore Descartes' and Locke's concept of knowledge is untenable. Reid furthermore holds that human beings are endowed with a disposition to accept or believe what otherstell us („the principle of credulity”). The working of this principle is refined through all kinds of experience. What Reid says or shows is how this disposition in fact operates. Many epistemologists, however, have higher aspirations and look for reasons or arguments that can justify our factual acceptance of testimony. The inductive argument Hume offers, it is argued, is unconvincing. There is even reason to think that the principle of credulity can never be justified by adducing reasons. This does not imply, however, that acceptance of testimony is unjustified. Whether or not it is depends, among other things, on the concept of justification one uses. On an internalist concept of justification (as Locke's or Hume's) this disposition may never be justified. But on an externalist conception it may. This may be disappointing, given some widely held philosophical aspirations, but at the same time it is, as Alston has said, a lesson in intellectual humility. (shrink)

James Van Cleve here shows why Thomas Reid (1710-96) deserves a place alongside the other canonical figures of modern philosophy. He expounds Reid's positions and arguments on a wide range of topics, taking interpretive stands on points where his meaning is disputed and assessing the value of his contributions to issues philosophers are discussing today. -/- Among the topics Van Cleve explores are Reid's account of perception and its relation to sensation, conception, and belief; his nativist account of the origin (...) of the concepts of space and power; his attempt to clear the way for the belief that the things we directly perceive are external things, not ideas in our minds; his stand on the distinction between primary and secondary qualities; his account of his externalist reply to philosophical skepticism, his volitional theory of action, his use of the distinction between event causation and agent causation to understand freedom of the will, and his criticism of Hume and anticipation of Moore on the analysis of moral judgment. -/- The most comprehensive work on Reid in a quarter century, this book will be welcomed by students of early modern philosophy, epistemology, the philosophy of perception, and the philosophy of action.
