BackgroundIn the Canadian Alliance for Healthy Hearts and Minds (CAHHM) cohort, participants underwent magnetic resonance imaging (MRI) of the brain, heart, and abdomen, that generated incidental findings (IFs). The approach to managing these unexpected results remain a complex issue. Our objectives were to describe the CAHHM policy for the management of IFs, to understand the impact of disclosing IFs to healthy research participants, and to reflect on the ethical obligations of researchers in future MRI studies.MethodsBetween 2013 and 2019, 8252 participants (...) (mean age 58 ± 9 years, 54% women) were recruited with a follow-up questionnaire administered to 909 participants (40% response rate) at 1-year. The CAHHM policy followed a restricted approach, whereby routine feedback on IFs was not provided. Only IFs of severe structural abnormalities were reported.ResultsSevere structural abnormalities occurred in 8.3% (95% confidence interval 7.7–8.9%) of participants, with the highest proportions found in the brain (4.2%) and abdomen (3.1%). The majority of participants (97%) informed of an IF reported no change in quality of life, with 3% of participants reporting that the knowledge of an IF negatively impacted their quality of life. Furthermore, 50% reported increased stress in learning about an IF, and in 95%, the discovery of an IF did not adversely impact his/her life insurance policy. Most participants (90%) would enrol in the study again and perceived the MRI scan to be beneficial, regardless of whether they were informed of IFs. While the implications of a restricted approach to IF management was perceived to be mostly positive, a degree of diagnostic misconception was present amongst participants, indicating the importance of a more thorough consent process to support participant autonomy.ConclusionThe management of IFs from research MRI scans remain a challenging issue, as participants may experience stress and a reduced quality of life when IFs are disclosed. The restricted approach to IF management in CAHHM demonstrated a fair fulfillment of the overarching ethical principles of respect for autonomy, concern for wellbeing, and justice. The approach outlined in the CAHHM policy may serve as a framework for future research studies.Clinical trial registrationhttps://clinicaltrials.gov/ct2/show/nct02220582. (shrink)

In this paper it is argued that Hintikka's game theoreticalsemantics for Independence Friendly logic does not formalize theintuitions about independent choices; it rather is aformalization of imperfect information. Furthermore it is shownthat the logic has several remarkable properties (e.g.,renaming of bound variables is not allowed). An alternativesemantics is proposed which formalizes intuitions aboutindependence.

This paper is part II of a trilogy on the transition from classical particle mechanics to relativistic continuum mechanics that one of the authors is working on. The first part, on the Trouton experiment, was published in the Stachel festschrift (Janssen 2003). This paper focuses on the Lorentz-Poincaré electron, and, in particular, on the "Poincaré pressure" or "Poincaré stresses" introduced to stabilize the electron. It covers both the original argument by Poincaré (1906) and a modern relativistic argument for adding (...) a negative pressure term to the system's energy-momentum tensor inspired by the work of Laue (1911a, b). It highlights the importance of a paper by Lorentz (1899) in this context and of the "electromagnetic mechanics" of Abraham (1903). (shrink)

The relationship between Albert Einstein’s special theory of relativity and Hendrik A. Lorentz’s ether theory is best understood in terms of competing interpretations of Lorentz invariance. In the 1890s, Lorentz proved and exploited the Lorentz invariance of Maxwell’s equations, the laws governing electromagnetic fields in the ether, with what he called the theorem of corresponding states. To account for the negative results of attempts to detect the earth’s motion through the ether, Lorentz, in effect, had to assume that the laws (...) governing the matter interacting with the fields are Lorentz invariant as well. This additional assumption can be seen as a generalization of the well-known contraction hypothesis. In Lorentz’s theory, it remained an unexplained coincidence that both the laws governing fields and the laws governing matter should be Lorentz invariant. In special relativity, by contrast, the Lorentz invariance of all physical laws directly reflects the Minkowski space-time structure posited by the theory. One can use this observation to produce a common-cause argument to show that the relativistic interpretation of Lorentz invariance is preferable to Lorentz’s interpretation. (shrink)

In the course of his work on optics and electrodynamics in systems moving through the ether, the 19th-century medium for light waves and electric and magnetic fields, Lorentz discovered and exploited the invariance of the free-field Maxwell equations under what Poincaré later proposed to call Lorentz transformations. To account for the negative results of optical experiments aimed at detecting the earth’s motion through the ether, Lorentz, in effect, assumed that the laws governing matter interacting with light waves are Lorentz invariant (...) as well. Like Lorentz, Einstein first encountered the Lorentz transformations in electrodynamics. Unlike Lorentz, for whom the transformation merely provided convenient mathematical substitutions, but like Poincaré, Einstein recognized that the Lorentz-transformed quantities are the measured quantities for the moving observer. More importantly, Einstein recognized that the Lorentz invariance of all physical laws had nothing to do with electrodynamics per se, but reflected the kinematics in a new relativistic space-time, to be named after Minkowski who worked out its geometry a few years later.

This paper takes as its point of departure two striking incongruities between scientiªc practice and trends in modern history and philosophy of science. (1) Many modern historians of science are so preoccupied with local scientiªc practices that they fail to recognize important non-local elements. (2) Many modern philosophers of science make a sharp distinction between explanation and evidence, whereas in scientiªc practice explanatory power is routinely used as evidence for scientiªc claims. I draw attention to one speciªc way in..

ABSTRACT Analytic philosophy in the mid-twentieth century underwent a major change of direction when a prior consensus in favour of extensionalism and descriptivism made way for approaches using direct reference, the necessity of identity, and modal logic. All three were first defended, in the analytic tradition, by one woman, Ruth Barcan Marcus. But analytic philosophers now tend to credit them to Kripke, or Kripke and Carnap. I argue that seeing Barcan Marcus in her historical context – one dominated by extensionalism (...) and descriptivism – allows us to see how revolutionary she was, in her work and influence on others. I focus on her debate with Quine, who found himself retreating to softened, and more viable, versions of his anti-modal arguments as a result. I make the case that Barcan's formal logic was philosophically well-motivated, connected to her views on reference, and well-matched to her overall views on ontology. Her nominalism led her to reject posits which could not be directly observed and named, such as possibilia. She conceived of modal calculi as facilitating counterfactual discourse about actual existents. I conclude that her contributions ought to be recognized as the first of their kind. Barcan Marcus must be awarded a central place in the canon of analytic philosophy. (shrink)

In his book, Physical Relativity, Harvey Brown challenges the orthodox view that special relativity is preferable to those parts of Lorentz's classical ether theory it replaced because it revealed various phenomena that were given a dynamical explanation in Lorentz's theory to be purely kinematical. I want to defend this orthodoxy. The phenomena most commonly discussed in this context in the philosophical literature are length contraction and time dilation. I consider three other phenomena of this kind that played a role in (...) the early reception of special relativity in the physics literature: the Fresnel drag effect in the Fizeau experiment, the velocity dependence of electron mass in beta-ray deflection experiments by Kaufmann and others, and the delicately balanced torques on a moving charged capacitor in the Trouton-Noble experiment. I offer historical sketches of how Lorentz's dynamical explanations of these phenomena came to be replaced by their now standard kinematical explanations. I then take up the philosophical challenge posed by the work of Harvey Brown and Oliver Pooley and clarify how those kinematical explanations work. (shrink)

If through rotation of a hollow sphere one produces a Coriolis field inside of it, then a centrifugal field is produced [...] that is not the same as the one that would occur in a rotating rigid system with the same Coriolis field. One can therefore not think of rotational forces as produced by the rotation of the fixed stars ….

This article tests the impact of Walmart's corporate decisions to end the sale of handguns at its stores in 1994 and to discontinue the sale of all firearms at approximately 59% of its stores in 2006 before resuming firearms sales at some of those stores in 2011. Using a difference-in-differences framework, we find that that from 1994 to 2005 counties with Walmarts robustly experienced a reduction in the suicide rate and experienced no change in the homicide rate. These models suggest (...) that Walmart's policy change caused a 3.3 to 7.5% reduction in the suicide rate within affected counties, which represents an estimated 5,104 to 11,970 lives saved over the studied period. In contrast, Walmart's 2006 and 2011 decisions to discontinue and subsequently resume the sale of rifles and shotguns in many of its stores was not associated with a robustly measured effect on homicide or suicide rates. We do find evidence that Walmart's 2006 decision to reduce the number of its stores that sold firearms caused a statistically significant reduction in the suicide rate for counties in which Walmart did not subsequently resume firearms sales.

Containing three previously unpublished papers by W.V. Quine as well as historical, exegetical, and critical papers by several leading Quine scholars including Hylton, Ebbs, and Ben-Menahem, this volume aims to remedy the comparative lack of historical investigation of Quine and his philosophical context.

Scientism has none of the virtues of science or philosophy, so let's do away with it.

In publications in 1914 and 1918, Einstein claimed that his new theory of gravity somehow relativizes the rotation of a body with respect to the distant stars and the acceleration of the traveler with respect to the stay-at-home in the twin paradox. What he showed was that phenomena seen as inertial effects in a space-time coordinate system in which the non-accelerating body is at rest can be seen as a combination of inertial and gravitational effects in a space-time coordinate system (...) in which the accelerating body is at rest. Two different relativity principles play a role in these accounts: the relativity of non-uniform motion, in the weak sense that the laws of physics are the same in the two space-time coordinate systems involved; what Einstein in 1920 called the relativity of the gravitational field, the notion that there is a unified inertio-gravitational field that splits differently into inertial and gravitational components in different coordinate systems. I provide a detailed reconstruction of Einstein's rather sketchy accounts of the twins and the bucket and examine the role of these two relativity principles. I argue that we can hold on to but that is either false or trivial. (shrink)

In 1907, Einstein set out to fully relativize all motion, no matter whether uniform or accelerated. After five failed attempts between 1907 and 1918, he finally threw in the towel around 1920, setting himself a new goal. For the rest of his life he searched for a classical field theory unifying gravity and electromagnetism. As he struggled to relativize motion, Einstein had to readjust both his approach and his objectives at almost every step along the way; he got himself hopelessly (...) confused at times; he fooled himself with fallacious arguments and sloppy calculations; and he committed what he later allegedly called the biggest blunder of his career: he introduced the cosmological constant. There is a very uplifting moral to this somber tale. Although Einstein never reached his original destination, the harvest of his thirteen-year odyssey is quite impressive. First of all, what is left of absolute motion in general relativity is far more palatable than absolute motion in special relativity or Newtonian theory. And general relativity does seem to eliminate absolute space. More importantly, from a modern physics point of view, Einstein produced a spectacular new theory of gravity based on what he called the equivalence principle. This principle says that inertial and gravitational effects are due to one and the same structure, the inertio-gravitational field, which in Einstein’s theory is represented by a metric tensor field. In addition to laying the foundations of this theory, Einstein, among other things, launched relativistic cosmology, suggested the possibility of gravitational waves, gave the first sensible definition of a space-time singularity, and caught on to the intimate connection between general covariance and energy-momentum conservation, an example of the general connection between symmetries and conservation laws of Noether’s theorems. These results more than make up for the—at least by the standards of modern philosophy of science—rather opportunistic way in which they were obtained.. (shrink)

Within the limited, but growing, literature on small business ethics almost no attention has been paid to the issue of social responsibility within ethnic minority businesses. Using a social capital perspective, this paper reports on an exploratory and qualitative investigation into the attitudinal and behavioural manifestations of CSR within small and medium-sized Asian owned or managed firms in the U.K., with particular reference to the distinctive factors motivating organisational responses. It offers alternative explanations of entrepreneurial behaviour and suggests areas for (...) further research. (shrink)

Scientists working on the wave theory of light in the 19 th century took it for granted that there had to be a medium for the propagation of light waves. This medium was called the luminiferous [= “light carrying”] ether. One of the central questions about this medium concerned its state of motion. There were two options: (1) The ether is completely undisturbed by matter moving through it (stationary or immobile ether); (2) Matter drags along the ether in its vicinity (...) and/or in its interior (dragged-along ether). Stellar aberration provided the main argument for the first option (even though a special dragging effect in the case of transparent matter had to be built into the theory to account for refraction). Polarization provided the main argument for the second option. These two options and the arguments pro and con will be explained in more detail below. (shrink)

The problem of simultaneous measurement of incompatible observables in quantum mechanics is studied on the one hand from the viewpoint of an axiomatic treatment of quantum mechanics and on the other hand starting from a theory of measurement. It is argued that it is precisely such a theory of measurement that should provide a meaning to the axiomatically introduced concepts, especially to the concept of observable. Defining an observable as a class of measurement procedures yielding a certain prescribed result for (...) the probability distribution of the set of values of some quantity (to be described by the set of eigenvalues of some Hermitian operator), this notion is extended to joint probability distributions of incompatible observables. It is shown that such an extension is possible on the basis of a theory of measurement, under the proviso that in simultaneously measuring such observables there is a disturbance of the measurement results of the one observable, caused by the presence of the measuring instrument of the other observable. This has as a consequence that the joint probability distribution cannot obey the marginal distribution laws usually imposed. This result is of great importance in exposing quantum mechanics as an axiomatized theory, since overlooking it seems to prohibit an axiomatic description of simultaneous measurement of incompatible observables by quantum mechanics.

This volume is the first systematic presentation of the work of Albert Einstein, comprising fourteen essays by leading historians and philosophers of science that introduce readers to his work. Following an introduction that places Einstein's work in the context of his life and times, the book opens with essays on the papers of Einstein's 'miracle year', 1905, covering Brownian motion, light quanta, and special relativity, as well as his contributions to early quantum theory and the opposition to his light quantum (...) hypothesis. Further essays relate Einstein's path to the general theory of relativity and the beginnings of two fields it spawned, relativistic cosmology and gravitational waves. Essays on Einstein's later years examine his unified field theory program and his critique of quantum mechanics. The closing essays explore the relation between Einstein's work and twentieth-century philosophy, as well as his political writings. (shrink)

A nationally representative survey of 2000 American adults shows broad support for prohibiting gun-possession on private land without the landowner's explicit permission. Many states have laws which permit concealed weapon carry unless explicitly prohibited by the landowner, but our survey suggests statistically-significant majorities would prefer “no carry” defaults with regard to homeowners, employers, and retailers. While respondents who are Republican, male, or gun owners are more likely to support “carry” defaults, we find that the majoritarian rejection of “carry” defaults does (...) not tend to vary by region or state. However, our survey does find majority support for a default right to possess guns in rented property and on an employer's parking lot. Respondents across all contexts also report substantial ignorance or misinformation about the law. Landowners who don't know or mistakenly believe that concealed carry is, by default, prohibited on their land may be less able to protect themselves by explicitly prohibiting such third-party possession.

Die Frage, ob es eine Geschichte der Weisen gibt, in denen Menschen sich selbst erleben, also eine Geschichte des Subjekts, wird vielfach als eine der sozialen Gebilde dargestellt, die den Einzelnen formen oder 'subjektivieren'. Sie kann sich aber auch auf die wechselnden Formen beziehen, in denen das Subjektsein selbst historisch beschrieben wurde, in all den variierenden Theorieentwürfen, die in der Psychologie, Philosophie, Anthropologie und den anderen Humanwissenschaften aufeinander folgten. Der Band untersucht die These, dass dieses theoretische Selbstwissen mehr bedeutet als (...) eine bloße Reihe ideengeschichtlicher Positionen; dass die Geschichte des Selbstwissens also von größerer Bedeutung für die Geschichte des Subjekts ist, als bisher vielfach zugestanden wurde. Das setzt einen Dialog zwischen (sozialwissenschaftlicher) Subjektivierungstheorie und (geisteswissenschaftlicher) Wissensgeschichte voraus, zu dem der Band eine Vorlage bildet.

. In responding to Taede Smedes, I first examine his thesis that the recent dialogue between science and religion has been dominated by scientism and does not take theology seriously. I then consider his views on divine action, free will and determinism, and process philosophy. Finally I use the fourfold typology of Conflict, Independence, Dialogue, and Integration to discuss his proposal for the future of science and religion.

Political decision-makers in the European Union are currently discussing the introduction of a mandatory uniform labelling scheme for meat and milk that provides information on husbandry systems similar to the already existent labelling scheme in the EU egg market. The objective of this paper was to assess whether such information is relevant to consumers when buying meat and milk. The paper was based on a systematic synthesis of 53 scientific journal articles on empirical consumer studies. The review revealed that consumers (...) perceived the aspects of outdoor access, stocking density and floor type as important factors influencing animal welfare. On average, consumers not only had a positive attitude towards more animal welfare-friendly husbandry systems with outdoor access and space allowance but were also willing to pay a price premium for products from such systems. All studies on consumer segmentation identified at least one consumer segment that placed great importance on animal welfare-friendly husbandry systems. Interestingly, many studies identified one or more other segments who still had a significant preference for animal welfare-friendly products even though other product attributes were more important to them. Based on the findings, the paper presents conclusions regarding the labelling of husbandry systems for meat and milk. (shrink)

Gray's account of a brain mechanism for generating the contents of consciousness is incomplete. Adaptive advantages of conscious functioning need to be sought within the first-person affective sensation motivating flexibly goal-directed actions, as in Humphrey's sensory feedback theory.

Learned men of the twelfth century, especially the first half, frequently wrote about themselves and each other. Well-known examples of autobiographical writing include Guibert of Nogent's De vita sua or Monodiae, Rupert of Deutz's defense of his theological career in his Apologia attached to his commentary on the Benedictine rule, Peter Abelard's Historia calamitatum, and Gerald of Wales's De rebus a se gestis. Examples of biographical narrative are easily found: the life of St. Goswin included an account of Goswin defeating (...) Abelard in disputation; Baudri of Bourgueil wrote a poem about famous schools and scholars; the anonymous Metamorphosis Goliae provided characterizations of many masters; John of Salisbury's Metalogicon described the teaching methods of Bernard of Chartres and, in an autobiographical account of his own education, offered sketches of many of the leading masters in northern France, while Otto of Freising's Gesta Friderici I Imperatoris recounted parts of the academic careers of Abelard and Gilbert of Poitiers. It is therefore possible to read about twelfth-century scholars in their own words: the way they taught, their personalities, their ambitions, their disappointments; in short, their lives, or representations of their lives. Moving toward the end of the twelfth century and into the thirteenth century, however, there is very little comparable material, perhaps even none. In the thirteenth century, scholars wrote a great deal about being a scholar, but they preferred always to stress their collective identity, so that narrative accounts of particular scholarly lives did not find a place within the emerging universities. Why was there a change in the way in which scholars chose to represent themselves and each other, a change that involved obscuring their lives, both from themselves and from us? Answering that question will reveal the long-term significance of conflict between Schoolmen and monks and the impact of monastic ideals upon universities. It will show how the need for support from parties outside the university and internal debates about the true nature and purpose of learning came together, how ideas developed within the world of learning mattered when conflict led to the grant of privileges, and how specific ways of thinking became politically significant when particular events generated a certain kind of document in which those ways of thinking were embedded.

Consumer surveys repeatedly suggest that corporate social responsibility and products’ social, environmental, or ethical attributes enhance consumers’ purchase intentions. The realization that CSR still has only a minor impact on consumers’ actual purchase decisions thus represents a puzzling paradox. Whereas prior literature on consumer decision making provides valuable insights into the factors that impede or facilitate consumers’ socially responsible consumption decisions, such elements may be only the tip of the iceberg. To gain a fuller understanding of the CSR–consumer paradox, this (...) study proposes investigating the phenomenon through additional theoretical lenses, namely, a clinical psychology, an evolutionary psychology/biology, a social psychology, and an economic and economic psychology lens. From these four unique theoretical lenses, the authors derive an integrative framework and draw several propositions for further research. (shrink)

This discussion paper continues the debate over risk‐related standards of mental competence which appears in Bioethics 5. Dan Brock there defends an approach to mental competence in patients which defines it as being relative to differing standards, more or less rigorous depending on the degree of risk involved in proposed treatments. But Mark Wicclair raises a problem for this approach: if significantly different levels of risk attach, respectively, to accepting and refusing the same treatment, then it is possible, on this (...) account, for a patient to be considered competent to accept, but not refuse, the treatment, or vice versa. I argue that this puzzle does not constitute a genuine problem for a risk‐related standard. To this end I focus on the situation where, of two mutually exclusive options, one is riskier, but offering more pronounced benefit, while the other is safer, but offering less benefit. I argue for this proposition: it can take far less insight to know that the safe option is good than to know that the risky option is better. Now say one is actually informed enough to know that the safe option is good, but not enough to know whether the risky option is better; in such a case one is competent to say yes to that first option (the safe one), but not to say yes to the other. (I argue in passing that Pascal's Wager can be interpreted as having precisely this deliberative structure.) I thus conclude that cases do indeed exist where one can be competent to say yes but not no, or vice versa; and that it is thus not an anomaly in the risk‐related standard that it entails the existence of such cases.

Twenty-first century critics frequently misread Quinean ontological commitment as a toothless doctrine of anti-metaphysical pragmatism. Janssen-Lauret's historical investigations reveal that they misinterpret the influence of Quine's naturalism. His naturalistic view of philosophy as continuous with science informs a much more interesting conception of ontological commitments as generated by indispensable explanatory roles. But Janssen-Lauret uncovers a previously undetected weakness in Quine's meta-ontology. Careful examination of his debate with another naturalistic nominalist, Ruth Barcan Marcus, reveals that his holism leaves him (...) blind to her acquaintance-based ontological commitment via proper names. Janssen-Lauret examines some crucial misunderstandings between Barcan Marcus and Quine, centring on their wildly different interpretations of proper names, quantification and identity, and argues that these are motivated by their diametrically opposed positions on epistemology.

Geoffrey Cantor and Chris Kenny have criticized attempts to classify various ways of relating science and religion. They hold that all typologies are too simple and too static to illuminate the complex and changing historical interactions of science and religion. I argue that typologies serve a useful pedagogical function even though every particular interaction must be seen in its historical context. I acknowledge the problems in making distinctions between categories of classification and examine some alternative typologies that have been proposed. (...) I leave as an open question whether my fourfold typology is applicable to differing religious traditions. Finally I consider some parallels between typologies for science‐religion interactions and typologies for relationships between religions. Can our discussions be both interdisciplinary and interreligious without the danger of imposing the conceptual framework of one discipline or religious tradition on another discipline or tradition?

This paper explores the influence of Søren Kierkegaard upon Paul Feyerabend by examining their common criticisms of totalising accounts of human nature. Both complained that philosophical and scientific theories of human nature which were methodologically committed to objectivity and abstraction failed to capture the richness of human experience. Kierkegaard and Feyerabend argued that philosophy and the science were threatening to become obstacles to human development by imposing abstract theories of human nature and reality which denied the complexities of both. In (...) both cases, this took the form of asserting an ‘existential’ criterion for the assessment of philosophical and scientific theories. Kierkegaard also made remarks upon the inappropriateness of applying natural scientific methods to human beings which Feyerabend later expanded and developed in his criticisms of the inability of the ‘scientific worldview’ to accommodate the values necessary to a flourishing human life. I conclude by noting some differences between Kierkegaard and Feyerabend’s positions and by affirming the value of existential criticisms of scientific knowledge.Keywords: Feyerabend; Kierkegaard; Objectivity;ion; Human nature.

The research investigates how LPOs portray the benefits of this form of socially responsible purchasing and suggests a business case construct based on four component elements. It also highlights a number of contextual factors that appear to have shaped business case rationales. (...) The paper concludes with a discussion of issues of cost and contingent influences affecting SD programmes and points to possible areas for future research. (shrink)
