The concept of substantial equivalence,introduced for the risk assessment of geneticallymodified (GM) food, is a reducing concept because itignores the context in which these products have beenproduced and brought to the consumer at the end of thefood chain. Food quality cannot be restricted to meresubstance and food acts on human beings not only atthe level of nutrition but also through theirrelationship to environment and society. To make thiscontext explicit, I will introduce an ``equivalencescale'' for the evaluation of food (...) chains (GM or notGM). By contrast with substantial equivalence, whichinvolves mainly quantitative, analytical methods ofevaluation, ``qualitative equivalence'' refers to ``less''or non-substantial factors that require new methodsof evaluation based on qualitative principles.``Ethical equivalence'' refers to factors that show themoral value contained in food products. To analyze thedifferent levels at which ethics is needed in foodchains, I will use the French principles: ``Liberty,Equality, Fraternity,'' or freedom, equality,solidarity, and add a fourth principle:sustainability. Sustainability, solidarity, andfreedom can be applied to the evaluation ofenvironmental, socio-economic, and socio-culturalethical equivalence, respectively. Equality refers tojustice and should operate so as to guarantee thatsustainability, solidarity, and freedom are satisfied.I suggest that ethics can provide a basis for arenewal of the food chain concept. Besides QualityAssurance, it is now essential to develop an ``EthicalAssurance'' and this equivalence scale could provide abasis to set up ``Ethical Assurance Standards'' (EAS)for food chains.

When intense public controversy erupted around agricultural biotechnology in the late 1990s, critics found opportunities to challenge risk assessment criteria and test methods for genetically modified products. In relation to GM food, they criticized the concept of substantial equivalence, which European Union and United States regulators had adopted as the basis for a harmonized, science-based approach to risk assessment. Competing policy agendas framed scientific uncertainty in different ways. Substantial equivalence was contested and eventually recast to accommodate (...) some criticisms. To explain how the concept changed, this article links two analytical perspectives. Regulatory-science perspectives illuminate how the scientification of politics and politicization of science led to shifts in the boundary between science and policy. Governance perspectives illuminate how the collective problem for policy was redefined to provide a new common ground for some stakeholders. Overall, substantial equivalence was recast to govern the social conflict and address legitimacy problems of regulatory procedures. (shrink)

Substantial equivalence has beenintroduced to assess novel foods, includinggenetically modified food, by means ofcomparison with traditional food. Besides anumber of objections concerning its scientificvalidity for risk assessment, the maindifficulty with SE is that it implies that foodcan be qualified on a purely substantial basis.SE embodies the assumption that only reductivescientific arguments are legitimate fordecision-making in public policy due to theemphasis on legal issues. However, the surge ofthe food debate clearly shows that thistechnocratic model is not accepted anymore. (...) Food is more than physico-chemical substanceand encompasses values such as quality andethics. These values are legitimate in theirown right and require that new democraticprocesses are set up for transverse,transdisciplinary assessment in partnershipwith society. The notion of equivalence canprovide a reference scale in which to examinethe various legitimate factors involved:substance, quality, and ethics. QE requires that newqualitative methods of evaluation that are notbased on reductive principles are developed. EEcan provide a basis for the development of anEthical Assurance as a counterpart of QualityAssurance in the food sector. In France, asecond circle of expertise is being set up toaddress the social issues in food public policybeside classical risk assessment by the firstcircle of expertise. Since ethics is likely tobecome an organizing principle of the secondcircle, the equivalence ethical framework canprove instrumental in this context. (shrink)

We construct a notion of teleparallelization for Newton-Cartan theory, and show that the teleparallel equivalent of this theory is Newtonian gravity; furthermore, we show that this result is consistent with teleparallelization in general relativity, and can be obtained by null-reducing the teleparallel equivalent of a five-dimensional gravitational wave solution. This work thus strengthens substantially the connections between four theories: Newton-Cartan theory, Newtonian gravitation theory, general relativity, and teleparallel gravity.

Deflationism is usually thought to differ from the correspondence theory over whether truth is a substantial property. However, I argue that this notion of a ‘substantial property’ is tendentious. I further argue that the Equivalence Schema alone is sufficient to lead to idealism when combined with a pragmatist theory of truth. Deflationism thus has more powerful metaphysical implications than is generally thought and itself amounts to a kind of correspondence theory.

According to a widespread but implicit thesis in Bayesian confirmation theory, two confirmation measures are considered equivalent if they are ordinally equivalent—call this the “ordinal equivalence thesis”. I argue that adopting OET has significant costs. First, adopting OET renders one incapable of determining whether a piece of evidence substantially favors one hypothesis over another. Second, OET must be rejected if merely ordinal conclusions are to be drawn from the expected value of a confirmation measure. Furthermore, several arguments and applications (...) of confirmation measures given in the literature already rely on a rejection of OET. I also contrast OET with stronger equivalence theses and show that they do not have the same costs as OET. On the other hand, adopting a thesis stronger than OET has costs of its own, since a rejection of OET ostensibly implies that people’s epistemic states have a very fine-grained quantitative structure. However, I suggest that the normative upshot of the paper in fact has a conditional form, and that other Bayesian norms can also fruitfully be construed as having a similar conditional form.

String dualities establish empirical equivalence between theories that often look entirely different with respect to their basic ontology and physical structure. Therefore, they represent a particularly interesting example of empirical equivalence in physics. However, the status of duality relations in string physics differs substantially from the traditional understanding of the role played by empirical equivalence. The paper specifies three important differences and argues that they are related to a substantially altered view on the underdetermination of theory building.

In 1907 Einstein had the insight that bodies in free fall do not “feel” their own weight. This has been formalized in what is called “the principle of equivalence.” The principle motivated a critical analysis of the Newtonian and special-relativistic concepts of inertia, and it was indispensable to Einstein’s development of his theory of gravitation. A great deal has been written about the principle. Nearly all of this work has focused on the content of the principle and whether it (...) has any content in Einsteinian gravitation, but more remains to be said about its methodological role in the development of the theory. I argue that the principle should be understood as a kind of foundational principle known as a criterion of identity. This work extends and substantiates a recent account of the notion of a criterion of identity by William Demopoulos. Demopoulos argues that the notion can be employed more widely than in the foundations of arithmetic and that we see this in the development of physical theories, in particular space–time theories. This new account forms the basis of a general framework for applying a number of mathematical theories and for distinguishing between applied mathematical theories that are and are not empirically constrained.

”The last remnant of physical objectivity of space-time” is disclosed in the case of a continuous family of spatially non-compact models of general relativity. The physical individuation of point-events is furnished by the autonomous degrees of freedom of the gravitational field, which represent -as it were -the ontic part of the metric field. The physical role of the epistemic part is likewise clarified as embodying the unavoidable non-inertial aspects of GR. At the end the philosophical import of the Hole Argument (...) is substantially weakened and in fact the Argument itself dis-solved, while a specific four-dimensional holistic and structuralist view of space-time emerges, including elements common to the tradition of both substantivalism and relationism. The observables of our models undergo real temporal change: this gives new evidence to the fact that statements like the frozen-time character of evolution, as other ontological claims about GR, are model dependent.

Dark matter is an essential ingredient of the present Standard Cosmological Model, according to which only 5% of the mass/energy content of our universe is made of ordinary matter. In recent times, it has been argued that certain cases of gravitational lensing represent a new type of evidence for the existence of DM. In a recent paper, Peter Kosso attempts to substantiate that claim. His argument is that, although in such cases DM is only detected by its gravitational effects, gravitational (...) lensing is a direct consequence of Einstein's Equivalence Principle and therefore the complete gravitational theory is not needed in order to derive such lensing effects. In this paper I critically examine Kosso's argument: I confront the notion of empirical evidence involved in the discussion and argue that EEP does not have enough power by itself to sustain the claim that gravitational lensing in the Bullet Cluster constitutes evidence for the DM Hypothesis. As a consequence of this, it is necessary to examine the details of alternative theories of gravity to decide whether certain empirical situations are indeed evidence for the existence of DM. It may well be correct that gravitational lensing does constitute evidence for the DM Hypothesis—at present it is controversial whether the proposed modifications of gravitation all need DM to account for the phenomenon of gravitational lensing and if so, of which kind—but this will not be a direct consequence of EEP.

Madole & Harden's assertion that the effects derived from within-family genome-wide association studies (GWASs) and from randomized controlled trials (RCTs) are equivalent is misleading. GWASs are substantially more “non-unitary, non-uniform, and non-explanatory” than RCTs. While the within-family GWAS bring us closer to identifying genetic causes, whether it will change behavioral genetics into a causal science is an open question.

A recent rethinking of the early history of Quantum Mechanics deemed the late 1920s agreement on the equivalence of Matrix Mechanics and Wave Mechanics, prompted by Schrödinger's 1926 proof, a myth. Schrödinger supposedly failed to prove isomorphism, or even a weaker equivalence (“Schrödinger-equivalence”) of the mathematical structures of the two theories; developments in the early 1930s, especially the work of mathematician von Neumann provided sound proof of mathematical equivalence. The alleged agreement about the Copenhagen Interpretation, predicated (...) to a large extent on this equivalence, was deemed a myth as well. In response, I argue that Schrödinger's proof concerned primarily a domain-specific ontological equivalence, rather than the isomorphism or a weaker mathematical equivalence. It stemmed initially from the agreement of the eigenvalues of Wave Mechanics and energy-states of Bohr's Model that was discovered and published by Schrödinger in his first and second communications of 1926. Schrödinger demonstrated in this proof that the laws of motion arrived at by the method of Matrix Mechanics are satisfied by assigning the auxiliary role to eigenfunctions in the derivation of matrices (while he only outlined the reversed derivation of eigenfunctions from Matrix Mechanics, which was necessary for the proof of both isomorphism and Schrödinger-equivalence of the two theories). This result was intended to demonstrate the domain-specific ontological equivalence of Matrix Mechanics and Wave Mechanics, with respect to the domain of Bohr's atom. And although the mathematical equivalence of the theories did not seem out of the reach of existing theories and methods, Schrödinger never intended to fully explore such a possibility in his proof paper. In a further development of Quantum Mechanics, Bohr's complementarity and Copenhagen Interpretation captured a more substantial convergence of the subsequently revised (in light of the experimental results) Wave and Matrix Mechanics. -/- I argue that both the equivalence and Copenhagen Interpretation can be deemed myths if one predicates the philosophical and historical analysis on a narrow model of physical theory which disregards its historical context, and focuses exclusively on its formal aspects and the exploration of the logical models supposedly implicit in it. -/- .

The neutral theory of biodiversity assumes that coexisting organisms are equally able to survive, reproduce and disperse, but predicts that stochastic fluctuations of these abilities drive diversity dynamics. It predicts remarkably well many biodiversity patterns, although substantial evidence for the role of niche variation across organisms seems contradictory. Here, we discuss this apparent paradox by exploring the meaning and implications of ecological equivalence. We address the question whether neutral theory provides an explanation for biodiversity patterns and acknowledges causal (...) processes. We underline that ecological equivalence, although central to neutral theory, can emerge at local and regional scales from niche-based processes through equalizing and stabilizing mechanisms. Such emerging equivalence corresponds to a weak conception of neutral theory, as opposed to the assumption of strict equivalence at individual level in the strong conception. We show that this duality is related to diverging views on hypothesis-testing and modeling in ecology. In addition, the stochastic dynamics exposed in neutral theory are pervasive in ecological systems and, rather than a null hypothesis, ecological equivalence is best understood as a parsimonious baseline to address biodiversity dynamics at multiple scales.

A recent rethinking of the early history of Quantum Mechanics deemed the late 1920s agreement on the equivalence of Matrix Mechanics and Wave Mechanics, prompted by Schrödinger’s 1926 proof, a myth. Schrödinger supposedly failed to achieve the goal of proving isomorphism of the mathematical structures of the two theories, while only later developments in the early 1930s, especially the work of mathematician John von Neumman (1932) provided sound proof of equivalence. The alleged agreement about the Copenhagen Interpretation, predicated (...) to a large extent on this equivalence, was deemed a myth as well. If such analysis is correct, it provides considerable evidence that, in its critical moments, the foundations of scientific practice might not live up to the minimal standards of rigor, as such standards are established in the practice of logic, mathematics, and mathematical physics, thereby prompting one to question the rationality of the practice of physics. In response, I argue that Schrödinger’s proof concerned primarily a domain-specific ontological equivalence, rather than the isomorphism. It stemmed initially from the agreement of the eigenvalues of Wave Mechanics and energy-states of Bohr’s Model that was discovered and published by Schrödinger in his First and Second Communications of 1926. Schrödinger demonstrated in this proof that the laws of motion arrived at by the method of Matrix Mechanics could be derived successfully from eigenfunctions as well (while he only outlined the reversed derivation of eigenfunctions from Matrix Mechanics, which was necessary for the proof of isomorphism of the two theories). This result was intended to demonstrate the domain-specific ontological equivalence of Matrix Mechanics and Wave Mechanics, with respect to the domain of Bohr’s atom. And although the full-fledged mathematico-logical equivalence of the theories did not seem out of the reach of existing theories and methods, Schrödinger never intended to fully explore such a possibility in his proof paper. In a further development of Quantum Mechanics, Bohr’s complementarity and Copenhagen Interpretation captured a more substantial convergence of the subsequently revised (in light of the experimental results) Wave and Matrix Mechanics. I argue that both the equivalence and Copenhagen Interpretation can be deemed myths if one predicates the philosophical and historical analysis on a narrow model of physical theory which disregards its historical context, and focuses exclusively on its formal aspects and the exploration of the logical models supposedly implicit in it.

Numerous instruments have been developed to elicit numerical values that represent the strength of preference for different health states. However, relatively few studies have attempted to analyse the reasoning processes that people employ when they are asked to answer questions based on these elicitation methods. The lottery equivalents method is a preference elicitation instrument that has recently received some attention in the literature. This study attempts a qualitative analysis of the use of this instrument on a group of 25 relatively (...) highly educated respondents. For each of three health states considered in the study, a substantial number of respondents refused to trade the chance of survival for a possible improvement in the health state. Therefore, many respondents violated an assumption that is necessary for the lottery equivalents instrument to generate cardinal health state values. These findings place a question mark against the usefulness of the lottery equivalents method, and add weight to the suspicion that ‘preferences’ are constructed according to how questions are framed.

Category Theory has developed rapidly. This book aims to present those ideas and methods which can now be effectively used by Mathe­ maticians working in a variety of other fields of Mathematical research. This occurs at several levels. On the first level, categories provide a convenient conceptual language, based on the notions of category, functor, natural transformation, contravariance, and functor category. These notions are presented, with appropriate examples, in Chapters I and II. Next comes the fundamental idea of an adjoint (...) pair of functors. This appears in many substantially equivalent forms: That of universal construction, that of direct and inverse limit, and that of pairs offunctors with a natural isomorphism between corresponding sets of arrows. All these forms, with their interrelations, are examined in Chapters III to V. The slogan is "Adjoint functors arise everywhere". Alternatively, the fundamental notion of category theory is that of a monoid -a set with a binary operation of multiplication which is associative and which has a unit; a category itself can be regarded as a sort of general­ ized monoid. Chapters VI and VII explore this notion and its generaliza­ tions. Its close connection to pairs of adjoint functors illuminates the ideas of universal algebra and culminates in Beck's theorem characterizing categories of algebras; on the other hand, categories with a monoidal structure lead inter alia to the study of more convenient categories of topological spaces.

The caliber of recent discourse regarding geneticallymodified organisms (GMOs) has suffered from a lack of consensuson terminology, from the scarcity of evidence upon which toassess risk to health and to the environment, and from valuedifferences between proponents and opponents of GMOs. Towardsaddressing these issues, we present the thesis that GM should bedefined as the forcible insertion of DNA into a host genome,irrespective of the source of the DNA, and exclusive ofconventional or mutation breeding.Some defenders of the commercial use of GMOs (...) have referred to thescientific work of GMO critics as ``junk science.'''' Such a claim isfalse and misleading, given that many papers critical of both theutility and safety of GMOs have been published in peer reviewedjournals by respected scientists. In contrast, there is a dearthof peer reviewed work to substantiate the frequently heardassertions of either safety or utility in GMOs. The polarity,which now characterizes much of the public discourse on GMOs,reflects not simply scientific disagreement, but alsodisagreement in underlying value assumptions. Value differencesstrongly affect the assessment of both benefit and harm fromGMOs. (shrink)

The present joint contribution offers a tentative comprehensive re-interpretation of Pāṇini’s rule A 2.3.46, and shows how that rule teaches the application of the nominative ending without making use of the notion of “subject,” a notion that belongs to other grammatical systems, but not to Pāṇini’s. We discuss the controversial domain of some segments of its wording by attempting to adhere to Pāṇini’s framework and his usus scribendi. In particular, we read the first constituent of the compound prātipadikārtha­ liṅgaparimāṇavacana­ as (...) a genitive depending on a dvandva made up of three constituents, i.e., artha­, liṅga­, and parimāṇavacana­, and we take parimāṇa­ as denoting a quantity that, combining with vacana­, is substantially equivalent to the concept of grammatical number in modern linguistics. We finally show that our reading of A 2.3.46 is able to generate the nominative endings affixed to the subject and predicate of a nominal sentence: as a consequence, nominal sentences might actually not have been neglected by Pāṇini.

Risk governance of GM plants and GMfood products is presently subject to heatedscientific and public controversies. Scientistsand representatives of the biotechnologyindustry have dominated debates concerningsafety issues. The public is suspicious withregard to the motives of scientists, companies,and political institutions involved. Thedilemmas posed are nested, embracing valuequestions, scientific uncertainty, andcontextual issues. The obvious lack of data andinsufficient information concerning ecologicaleffects call for application of thePrecautionary Principle (PP). There are,however, divergent opinions among scientistsabout the relevance of putative hazards,definition of potential ``adverse effects,'' (...) andwhether actions should be taken to preventharm. The reliance on the concept ofsubstantial equivalence in safety evaluation ofGM food is equally controversial. Consequently,value assumptions embedded in a scientificframework may be a barrier for employment ofthe PP. One of our major conclusions is thatprecautionary GMP usage requires riskassessment criteria yet undeveloped, as well asbroader and more long-term conceptions of risk,uncertainty, and ignorance. Conflicts ofinterest and public participation are otherissues that need to be taken intoconsideration. GMP governance regimes that arejustifiable from a precautionary and ethicalpoint of view must transcend traditionalscientific boundaries to include alternativescientific perspectives as well as publicinvolvement.

In this paper I shall do three things. Firstly , I shall distinguish between three senses of “imagine”: one in which the word is used to report the occurrence of mental imagery; a second in which “imagined” is used as substantially equivalent to “thought”; and a third in which “imagine” is used as substantially equivalent to “suppose.” Secondly , I shall discuss Hume's thesis about imagination: both because, although this is set out as a plausible generalization about psychology, it nevertheless (...) seems to me that Hume dealt with a central philosophical problem concerning imagination—the relation of descriptions to imagery—in a way that is suggestive and fruitful; and—the main reason for mentioning Hume—because a study of the relation between imagining and imagining will help us to reinterpret his thesis from a mistaken one about psychology into a correct one about logic and language. Thirdly , I shall give thecentral arguments and the conclusion of the chapter on Imagination in The Concept of Mind , and comment on them. (shrink)

In ?The Labour Theory of Value and the Concept of Exploitation? I distinguished between two ways in which the labour theory of value is formulated, both of which are common. In the popular formulation, the amount of value a commodity has depends on how much labour was spent producing it. In the strict formulation, which is so called because it formulates the labour theory of value proper, the amount of value a commodity has depends on nothing about its history but (...) only on how much labour would (now) be required to produce something just like it. I argued that strict and popular formulations are often wrongly treated as substantially equivalent, and that the practice of conflating them sustains two false impressions: that the labour theory of value is a basis for saying that capitalists exploit workers, and that the labour theory of value is true. The present paper is a reply to Nancy Holmstrom's recent attempt, in ?Marx and Cohen on Exploitation and the Labor Theory of Value?, to refute the theses of the article referred to above. (shrink)

Today there is considerable disagreement between the US and the EU with respect to food safety standards. Issues include GMOs, beef hormones, unpasteurized cheese, etc. In general, it is usually asserted that Europeans argue for the precautionary principle (with exceptions such as the Sanitary and Phytosanitary Agreement where ``substantial equivalence,'' a form of familiarity, is used) while Americans defend risk analysis or what is sometimes described as the familiarityprinciple. This is not to suggest that EUmember countries agree on (...) how the precautionaryprinciple should be applied; considerabledifferences exist among nations as will benoted below.In this paper I review both positionsarguing that they are best understood asvariants of the homiletics of risk rather thanas differing scientific positions. I concludethat while science must necessarily enter intothe formulation of food and agriculturalstandards, state policy, private economicinterests, and the interface between the two(e.g., when democratic states are successfullylobbied to support particular privateinterests), play important roles in determininghow particular risks will be treated. Moreover,I argue that the role of science mustnecessarily be limited if its credibility is tobe preserved. (shrink)

The words χρxs22EF and δεxs1FD6 with their inflectional and dialectic variations, are less definite and stable in their semantic range than the other Greek expressions for the general ideas of necessity, obligation, or propriety. Their semantic boundaries varied with the dialect, province of literature, and period–which cannot, indeed, be entirely separated. From Homer to Aristotle there is a steady trend, so plain that the slight notice taken of it is rather surprising. Everyone sees that the two are sometimes differentiated; yet (...) it seems to be loosely taken for granted that they are substantially equivalent, and that either may, almost anywhere, be taken as an equivalent of the verbal in -τxs22EFος. The statements in Liddell and Scott under χρxs22EF present an admirable confusion of all periods and styles, and J. H. H. Schmidt, with no mention of dates, makes a distinction that resembles a reversal of the true relation. (shrink)

Biological systems are highly complex, and for this reason there is a considerable degree of uncertainty as to the consequences of making significant interventions into their workings. Since a number of new technologies are already impinging on living systems, including our bodies, many of us have become participants in large-scale “social experiments”. I will discuss biological complexity and its relevance to the technologies that brought us BSE/vCJD and the controversy over GM foods. Then I will consider some of the complexities (...) of our social dynamics, and argue for making a shift from using the precautionary principle to employing the approach of evaluating the introduction of new technologies by conceiving of them as social experiments.

A substantial body of evidence suggests that autobiographical recollection and simulation of future happenings activate a shared neural network. Many of the neural regions implicated in this network are affected in patients with bipolar disorder , showing altered metabolic functioning and/or structural volume abnormalities. Studies of autobiographical recall in BD reveal overgeneralization, where autobiographical memory comprises primarily factual or repeated information as opposed to details specific in time and in place and definitive of re-experiencing. To date, no study has (...) examined whether these deficits extend to future event simulation. We examined the ability of patients with BD and controls to imagine positive, negative and neutral future events using a modified version of the Autobiographical Interview that allowed for separation of episodic and non-episodic details. Patients were selectively impaired in imagining future positive, negative, and neutral episodic details; simulation of non-episodic details was equivalent across groups. (shrink)

Expressively equivalent logical languages can enunciate logical notions in notationally diversified ways. Frege’s Begriffsschrift, Peirce’s Existential Graphs, and the notations presented by Wittgenstein in the Tractatus all express the sentential fragment of classical logic, each in its own way. In what sense do expressively equivalent notations differ? According to recent interpretations, Begriffsschrift and Existential Graphs differ from other logical notations because they are capable of “multiple readings.” We refute this interpretation by showing that there are at least three different kinds (...) of such multiple readings. While readings of the first kind do not capture any essential difference among notations but only among vocabularies, corresponding to readings of the second and the third kind two general parameters according to which notations may differ are defined: linearity vs. non-linearity, and tabularity vs. non-tabularity. This answers the question of how there can be substantially different but expressively equivalent logical notations. (shrink)

Is truth a substantial feature of truth-bearers? Correspondence theorists answer in the affirmative, deflationists in the negative. Correspondence theorists cite in their defense the dependence of truth on meaning or representational content. Deflationists in turn cite the conceptual centrality of simple equivalences such as ''Snow is white' is true iff snow is white'' and 'It is true that snow is white iff snow is white'. The apparent facts to which these theorists appeal correspond to some of our firmest and (...) most basic convictions about truth. An account of truth that fails to accommodate either sort of apparent fact is inadequate. The account presented in this essay attempts to avoid this inadequacy by 'deflating' truth for propositions but 'inflating' truth for entities that express propositions, thus drawing from the insights of both deflationists and correspondence theorists.

Integrating the study of human diversity into the human evolutionary sciences requires substantial revision of traditional conceptions of a shared human nature. This process may be made more difficult by entrenched, 'folkbiological' modes of thought. Earlier work by the authors suggests that biologically naive subjects hold an implicit theory according to which some traits are expressions of an animal's inner nature while others are imposed by its environment. In this paper, we report further studies that extend and refine our (...) account of this aspect of folkbiology. We examine biologically naive subjects' judgments about whether traits of an animal are 'innate', 'in its DNA' or 'part of its nature'. Subjects do not understand these three descriptions to be equivalent. Both innate and in its DNA have the connotation that the trait is species-typical. This poses an obstacle to the assimilation of the biology of polymorphic and plastic traits by biologically naive audiences. Researchers themselves may not be immune to the continuing pull of folkbiological modes of thought. (shrink)

Fourteen subjects were tape‐recorded while they undertook to find a law to summarize numerical data they were given. The source of the data was not identified, nor were the variables labeled semantically. Unknown to the subjects, the data were measurements of the distances of the planets from the sun and the periods of their revolutions about it—equivalent to the data used by Johannes Kepler to discover his third law of planetary motion.Four of the 14 subjects discovered the same law as (...) Kepler did (the period varies as the 3/2 power of the distance), and a fifth came very close to the answer. The subiects' protocols provide a detailed picture of the problem‐solving searches they engaged in, which were mainly, but not exclusively, in the space of possible functions for fitting the data, and provide explanations as to why some succeeded and the others failed.The search heuristics used by the subjects are similar to those embodied in the BACON program, computer simulation of certain scientific discovery processes. The experiment demonstrates the feasibility of examining some of the processes of scientific discovery by recreating, in the laboratory, discovery situations of substantial historical relevance. It demonstrates also, that under conditions rather similar to those of the original discoverer, a law can be rediscovered by persons of ordinary intelligence (i.e., the intelligence needed for academic success in a good university). The data for the successful subjects reveal no “creative” processes in this kind of a discovery situation different from those that are regularly observed in all kinds of problem‐solving settings.

In this article, we offer a detailed study of two important episodes in the early history of high-energy physics, namely the development of the Chew and the Nambu-Jona-Lasinio models. Our study reveals that both models resulted from the combination of an old Hamiltonian, which had been introduced by earlier researchers, and two new approximation methods developed by Chew and by Nambu and Jona-Lasinio. These new approximation methods, furthermore, were the key component behind the models’ success. We take this historical investigation (...) to support two philosophical theses about the manner in which scientific modelling operates in high-energy physics. Both of these theses run counter to a view that is commonly accepted among philosophers of science: the view that all approximations can be embedded within an equivalent idealized system, and that whatever role the former might play in scientific modelling is therefore parasitic on the much more substantial work performed by the latter. Our first thesis, which we call “Distinctness,” states that approximation methods constitute an independent category of theoretical output from idealized systems. We thus believe that approximations and idealized systems constitute two independent types of objects, both of which are essential to the practice of modelling. Our second, more radical thesis is called “Content Determination.” Our claim here is that approximation methods can in fact be essential to assigning determinate physical content to the idealized systems with which they jointly operate. As we show, this is due to the fact that quantum field theory allows for a very thin characterization of idealized systems only, making the use of approximations necessary to supply additional content. We conclude the paper with a few reflections about the manner in which our two theses can be used to articulate David Kaiser’s views on the “vanishing of scientific theory” in physics after WWII.

Legal concepts and notions are deeply affected by religions, ethics, philosophy and the culture of a particular nation. As Friedman Comparing legal cultures, Dartmouth, Aldershot, 1997, p. 34) highlights, understanding legal culture is a crucial factor as it both affects their translation and interpretation and consequently has an impact on the application of law. This increases in importance, for example, in the context of the principle of mutual trust and recognition of judgments assumed by the European Union as the cornerstone (...) of judicial co-operation in the European Union, which would not be possible without the trust in each other’s justice system and the respect for the different legal systems and traditions of the Member States. In that vein, ‘the Third Space’, where legal concepts and notions of multiple origins meet and where their meanings are negotiated, transformed, translated and integrated into various socio-political and cultural contexts has acquired an immense significance. Although there may be natural similarities between legal professions in the European Union, they could differ quite substantially as they are deeply rooted in the history and societal evolution of a country; therefore, they are generally regulated at a national, not a European level. In light of the above, the author intends to perform an in-depth analysis of key terminology in the field of names of legal professions which exist in the Member States of the European Union. The author focuses on the terms which refer to the legal profession of lawyers as they might pose obstacles in translation and interpretation due to different functions and roles these legal professionals play in their legal systems or due to the lack of their equivalents in other legal systems. The terminology is compared to present similarities and differences in their meaning, particularly putting some emphasis on socio-political and cultural contexts. The research methods encompass the analysis of relevant literature and the terminological analysis of the research material, which includes the information on legal professions provided by particular Member States on the European e-Justice portal and relevant national regulations in that respect. Finally, the author draws the conclusion that a thorough analysis of the functions and roles of a particular legal profession in socio-political and cultural contexts is required before the translation and interpretation of the term is provided as it helps to avoid ambiguity and makes legal communication precise.

In lieu of an abstract, here is a brief excerpt of the content:18 HUME AND THE STANDARD OF TASTE David Hume's critical theories, although fragmentary, have drawn increasingly serious attention in the twentieth century, yet even in 1976 Peter Jones, in reassessing Hume's aesthetics, can describe one of the most substantial of his critical essays, "Of the Standard of Taste," as underrated. Jones praises it as "subtle and highly complex," but while I agree with that judgment I also find (...) the essay quite puzzling. I am struck by certain features which look like structural weaknesses and by what seem to be inconsistencies, even contradictions, in Hume's argument. But perhaps the gravest difficulty facing interpretation of this essay is the irony which Hume seems to use, for this raises the question of just how seriously we are to take some of the more conventional views contained in "Of the Standard of Taste." I can begin to illustrate my uneasiness by considering Hume's use of a tall tale from Don Quixote, Part II, chapter xiii. Hume introduces this in a lighthearted way as part of his definition of delicacy of taste. It is the story of Sancho Panza's two kinsmen, who are such sensitive judges of wine that they can detect the taint of iron and leather imparted to a hogshead by the presence in it of a key on a thong. Now there are some interesting differences between Hume's version of this tale and the original. For example, where Hume has the two tasters deliberate over their wine before pronouncing it good, except for the slight taste of leather or iron, Cervantes says the first merely tried it with the tip of his tongue and the second just sniffed it, without tasting any at all. Further, Hume says "both 2 were ridiculed for their judgment," but there is no such 19 reaction mentioned in the original. Lastly, Hume calls the cause of the taint of iron "an old key," where 3 Cervantes describes it as "little." In short, while in the original interest is in the sensitivity of the taste of Sancho' s kinsmen for its own sake, Hume's emphasis is more on the relation of their taste to that of other people. He makes the procedure of tasting the wine as normal as possible and he gives prominence to the reactions of other people. Hume both tones down the more fabulous aspects of the story, making it less extraordinary and hence a better starting-point for a generalization about taste, and makes more explicit the conflict of opinion about the wine. He is using the story not just to define delicacy of taste but also to relate it to the problem of aesthetic judgment and the standard of taste. This is confirmed by the application Hume makes of his example. First, he uses the analogy between physical and aesthetic taste to claim that delicacy in both consists of the ability to detect minute effects and make fine discriminations. But the crucial question is what serves, like the key on the thong in the story, to confirm to outsiders that a man's aesthetic judgment is in fact more delicate than his neighbours'. Hume's answer is "the general rules of beauty... to produce these general rules or avowed patterns of composition is like finding the key with the leathern thong; which justified the verdict of Sancho' s kinsmen, and confounded those pretended judges who had condemned them" (273). But of course producing a general rule is not exactly like finding a physical key on a thong, and Hume's use of the word "avowed" here, which he repeats later, raises the difficulty of how the principles of art become accepted, and by whom. But, that apart, there is something odd about the discussion since the avowed principle is used, with support from examples, to 20 convince a bad critic that he is wrong, on the grounds that his judgment does not accord with the general judgment. This is the opposite of Sancho's story, in which his kinsmen were in a minority, derided, adds Hume, by the dull majority, and only vindicated by the discovery of the tainting key and thong.

This book grew out of lectures. It is intended as an introduction to classical two-valued predicate logic. The restriction to classical logic is not meant to imply that this logic is intrinsically better than other, non-classical logics; however, classical logic is a good introduction to logic because of its simplicity, and a good basis for applications because it is the foundation of classical mathematics, and thus of the exact sciences which are based on it. The book is meant primarily for (...) mathematics students who are already acquainted with some of the fundamental concepts of mathematics, such as that of a group. It should help the reader to see for himself the advantages of a formalisation. The step from the everyday language to a formalised language, which usually creates difficulties, is dis cussed and practised thoroughly. The analysis of the way in which basic mathematical structures are approached in mathematics leads in a natural way to the semantic notion of consequence. One of the substantial achievements of modern logic has been to show that the notion of consequence can be replaced by a provably equivalent notion of derivability which is defined by means of a calculus. Today we know of many calculi which have this property. (shrink)

In developing their policy on paediatric medical assistance in dying (MAID), DeMichelis, Shaul and Rapoport decide to treat euthanasia and physician-assisted suicide as ethically and practically equivalent to other end-of-life interventions, particularly palliative sedation and withdrawal of care (WOC). We highlight several flaws in the authors’ reasoning. Their argument depends on too cursory a dismissal of intention, which remains fundamental to medical ethics and law. Furthermore, they have not fairly presented the ethical analyses justifying other end-of-life decisions, analyses and decisions (...) that were generally accepted long before MAID was legal or considered ethical. Forgetting or misunderstanding the analyses would naturally lead one to think MAID and other end-of-life decisions are morally equivalent. Yet as we recall these well-developed analyses, it becomes clear that approving of some forms of sedation and WOC does not commit one to MAID. Paediatric patients and their families can rationally and coherently reject MAID while choosing palliative care and WOC. Finally, the authors do not substantiate their claim that MAID is like palliative care in that it alleviates suffering. It is thus unreasonable to use this supposition as a warrant for their proposed policy. (shrink)

Although the path-integral formalism is known to be equivalent to conventional quantum mechanics, it is not generally obvious how to implement path-based calculations for multi-qubit entangled states. Whether one takes the formal view of entangled states as entities in a high-dimensional Hilbert space, or the intuitive view of these states as a connection between distant spatial configurations, it may not even be obvious that a path-based calculation can be achieved using only paths in ordinary space and time. Previous work has (...) shown how to do this for certain special states; this paper extends those results to all pure two-qubit states, where each qubit can be measured in an arbitrary basis. Certain three-qubit states are also developed, and path integrals again reproduce the usual correlations. These results should allow for a substantial amount of conventional quantum analysis to be translated over into a path-integral perspective, simplifying certain calculations, and more generally informing research in quantum foundations.

The technique of minimizing information (infomin) has been commonly employed as a general method for both choosing and updating a subjective probability function. We argue that, in a wide class of cases, the use of infomin methods fails to cohere with our standard conception of rational degrees of belief. We introduce the notion of a deceptive updating method and argue that non-deceptiveness is a necessary condition for rational coherence. Infomin has been criticized on the grounds that there are no higher (...) order probabilities that ‘support’ it, but the appeal to higher order probabilities is a substantial assumption that some might reject. Our elementary arguments from deceptiveness do not rely on this assumption. While deceptiveness implies lack of higher order support, the converse does not, in general, hold, which indicates that deceptiveness is a more objectionable property. We offer a new proof of the claim that infomin updating of any strictly-positive prior with respect to conditional-probability constraints is deceptive. In the case of expected-value constraints, infomin updating of the uniform prior is deceptive for some random variables but not for others. We establish both a necessary condition and a sufficient condition (which extends the scope of the phenomenon beyond cases previously considered) for deceptiveness in this setting. Along the way, we clarify the relation which obtains between the strong notion of higher order support, in which the higher order probability is defined over the full space of first order probabilities, and the apparently weaker notion, in which it is defined over some smaller parameter space. We show that under certain natural assumptions, the two are equivalent. Finally, we offer an interpretation of Jaynes, according to which his own appeal to infomin methods avoids the incoherencies discussed in this paper. (shrink)

We present several selection theorems for Borel relations, involving only Borel sets and functions, all of which can be obtained as consequences of closely related theorems proved in [DSR 96,99,01,01X] involving coanalytic sets. The relevant proofs given there use substantial set theoretic methods, which were also shown to be necessary. We show that none of our Borel consequences can be proved without substantial set theoretic methods. The results are established for Baire space. We give equivalents of some of (...) the main results for the reals. (shrink)

§1. Introduction. Ideals and filters of subsets of natural numbers have been studied by set theorists and topologists for a long time. There is a vast literature concerning various kinds of ultrafilters. There is also a substantial interest in nicely definable ideals—these by old results of Sierpiński are very far from being maximal— and the structure of such ideals will concern us in this announcement. In addition to being interesting in their own right, Borel and analytic ideals occur naturally (...) in the investigations of compact subsets of the space of all Baire class 1 functions on a Polish space, see [12, 18]. Also, certain objects associated with such ideals are of considerable interest and were quite extensively studied by several authors. Let us list here three examples; in all three of them I stands for an analytic or Borel ideal.1. The partial order induced by I on P: X ≥I Y iff X \ Y ϵ I and the partial order.2. Boolean algebras of the form P/I and their automorphisms.3. The equivalence relation associated with I: XEI Y iff X Δ ϵ I.In Section 4, we will have an opportunity to state some consequences of our results for equivalence relations as in 3. (shrink)

This Article discusses the impact of the international financial crisis on Brazilian capital markets. While the banking industry was not severely affected, leading nonfinancial corporations experienced severe financial turmoil. Two Brazilian corporations cross-listed in the United States - Sadia S.A. and Aracruz Celulose S.A. - suffered billion-dollar losses when the Brazilian real unexpectedly plummeted in relation to the dollar. Despite earlier disclosure that these companies had engaged only in pure hedging activity, these great losses were found to be the result (...) of their highly speculative trading in currencyderivatives. Consequently, several private lawsuits were filed both in the United States and in Brazil. This Article takes a novel approach to the transnational securities litigation debate by examining the particular consequences of private litigation in a developed and in an emerging country. It compares the types of lawsuits filed and their final outcomes. Despite substantially similar alleged wrongdoing, the outcomes for securities holders in each jurisdiction contrast strikingly. Only U.S. investors of both companies were able to obtain substantial financial recoveries; Brazilian investors obtained none. This Article examines the reasons behind these discrepant results and the consequent economic distributional effects on global securities markets after the U.S. Supreme Court decision in Morrison. The Article argues that Morrison aggravates such shareholder cross-border non pro rata compensation and transfers of company value from foreign to U.S. investors. It identifies a set of costs borne by foreign investors, and so far neglected by scholars, as a consequence of the current status of U.S. and international securities law regimes. These costs are the result not only of the typical “circularity problem” in securities litigation, but also of a “double circularity problem” as they fall on foreign shareholders who also suffered equivalent damages to those experienced by the U.S. class being compensated. The Article then discusses potential policy reforms for fixing transnational securities litigation. (shrink)

The article considers the principles underpinning the Ukrainian translation of Sextus Empiricus’ Outlines of Pyrrhonism and the translation strategy employed to render the fundamental concepts of his philosophy. The author believes that the translation should fully reproduce Outlines of Pyrrhonism’s rich word-forming terminological potential while preserving the internal form and etymological affinity of concepts. The basic principle is the unification of terms and key concepts. At the same time, an acceptable translation should adequately convey the original meaning of the text (...) and not its letter. The accurate translation of the contents is more important than an effort to use the same Ukrainian word throughout the translation as an equivalent of a particular word in the original. Besides, our translation seeks to abide by a principle that one has to avoid, whenever possible, Grecisms, Latinisms, and loan translations from the Russian language. In accord with this translation strategy, the paper describes the lexical and semantic fields of the basic concepts of skepticism, their paradigmatic and syntagmatic connections, and the range of these terms’ derivation, and substantiates the choice of Ukrainian equivalents. The explanations are illustrated by fragments of the contextual translation of several cognate word forms. The translation should take into account the extensive synonymy present in the Greek text and certain lability of the terminological system used by Sextus himself. The translator’s intentions aim at conveying the rich lexical imagery and metaphors of the Outlines of Pyrrhonism. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:American Journal of Philology 123.3 (2002) 319-328 [Access article in PDF] Introduction Mary-Kay Gamel Aristophanes' Thesmophoriazousai (Women at the Thesmophoria Festival) takes its title from an important three-day religious festival celebrated by women in honor of the goddess Demeter and her daughter Persephone. In this play, the playwright Euripides learns that the women of Athens plan to use the occasion of this women-only gathering to put him on trial (...) for the negative depictions of women in his plays. Euripides convinces a relative of his to dress in female costume, infiltrate the festival, and find out what the women are up to. The plot is quickly uncovered and the intruder captured. After several rescue schemes based on scenes from Euripides' tragedies fail, the playwright wins his relative's freedom by agreeing never to slander women again.Thesmophoriazousai has strong characters, a lively plot, and themes significant and timely both then and now—the relation between gender and performance, the representation of women in the media, an artist's responsibility. Yet it has received little attention from scholars and realized even fewer productions. The most obvious reason for neglect is the play's lack of explicit political commentary. Dover, for example, thinks it "leaves us with nothing difficult to think about... it has nothing to say about making peace" (1972, 169). The play contains considerable literary and dramatic criticism, in the form of both explicit commentary and parody, but this aspect has been far less studied than the contest between the tragedians in Aristophanes' Frogs. Some critics think the play weak compared to other plays of Aristophanes. Lever, for example, finds the conflict "not so clear-cut" since "the idea at stake... is only the stepping-off point for the fun that follows" (1956, 120). There are exceptions to this neglect. Norwood ranks Thesmophoriazousai far above Lysistrata: "for dazzling wit and irresistibly laughable farce combined this play is perhaps the world's finest masterpiece... glorious foolery suffused by a thrice-refined intellectual virtuosity that never misses a point, never overstresses it" (1931, 253-54). Rau (1967) gives the tragic parodies their due; in his substantial chapter on Thesmophoriazousai, Moulton declares it "skillfully composed and unified" (1981, 142); Bierl (2001) provides a detailed study of the role of the chorus. Yet the inattention continues: [End Page 319] Harriott (1986), Reckford (1987), and Segal (2001) mention the play only briefly.The years 2000 and 2001 seemed like a promising time to reconsider Thesmophoriazousai. The play's obscenity, which Norwood thought the only cause of its neglect, is no longer an obstacle. Recent scholarship on the religious and ritual context of Athenian drama helps us understand the role of the Thesmophoria and women's ritual in the play. And the rise of feminist criticism offers new perspectives on its portrayal of gender relations. Whitman unambiguously uses gender to denigrate the play: "These women are scarcely the warm wives and mothers of the Lysistrata, but rather a pack of vengeful furies... Femininity, whether real or assumed, is under a somewhat morbid cloud; by contrast, there is something genuinely refreshing about the masculinity of Mnesilochus [as he calls the Kinsman]... Comedy is virile, like Mnesilochus, and essentially truthful; tragedy is at best a hermaphroditic affair" (1964, 223-24). In a ground-breaking article first published in 1981, Zeitlin instead sees the play's connections between gender conflict and genre conflict—"the equivalence between intertextuality and intersexuality"—as the source of its power (1996, 375-416).Some feminists, however, question the function and effect of women's portrayal in Athenian plays written by males for male actors and possibly for an all-male audience. Zeitlin has argued that in Athenian tragedy, women are figures of male self-representation: "the self that is really at stake is to be identified with the male, while the woman is assigned the role of the radical other... functionally women are never an end in themselves, and nothing changes for them once they have lived out their drama on stage... they play the roles of catalysts, agents, instruments, blockers... and sometimes helpers or saviors for the male characters"...

Aldo Antonelli offers a novel view on abstraction principles in order to solve a traditional tension between different requirements: that the claims of science be taken at face value, even when involving putative reference to mathematical entities; and that referents of mathematical terms are identified and their possible relations to other objects specified. In his view, abstraction principles provide representatives for equivalence classes of second-order entities that are available provided the first- and second-order domains are in the equilibrium dictated (...) by the abstraction principles, and whose choice is otherwise unconstrained.entities are the referents of abstraction terms: such referents are to an extent indeterminate, but we can still quantify over them, predicate identity or non-identity, etc. Our knowledge of them is limited, but still substantial: we know whatever has to be true no matter how the representatives are chosen, i.e., what is true in all models of the corresponding abstraction principles. This view is backed up by an “austere” conception of universals, according to which these are first-order objects, i.e., ways of collecting first-order objects. Antonelli thus claims that second-order logic does not import any novel ontological commitment beyond ontology of first-order, naturalistically acceptable, objects. Moreover, in the case of arithmetic, even if Hume’s Principle is construed as described above, Frege’s Theorem goes through unaffected, since there is nothing in its proof that depends on an account of the “true nature” of numbers. A viable construal of logicism is then given by the combination of semantic nominalism and a naturalistic conception of abstraction. [Editors note]. (shrink)

This study investigates the effectiveness of experiential learning strategies in enhancing science subject competence among fifth-grade elementary students in Anbar Governorate, where traditional teaching methods dominate. Prior research indicates a lack of engagement and critical thinking among students, emphasizing the need for pedagogical approaches that promote active learning and real-world experiences. Employing a descriptive and experimental design, this research included two groups: an experimental group receiving instruction through experiential learning and a control group taught via traditional methods. The sample consisted (...) of 65 fifth-grade students from Al-Mu'min Primary School, chosen to ensure representativeness. Pre-experimental assessments ensured equivalence in variables such as age, intelligence, and previous academic achievement. The study's impact was evaluated using a post-test composed of 40 multiple-choice questions aligned with the science curriculum. Statistical analysis revealed a significant difference in mean achievement test scores between the groups, with the experimental group achieving a higher average score of 29.90 compared to the control group's 22.55. The calculated t-value was 10.11, surpassing the critical t-value of 2.00 at the 0.05 significance level, indicating strong evidence for the effectiveness of experiential learning strategies. Furthermore, the effect size measured using eta squared (η² = 0.63) confirmed a large impact on student achievement. The findings signify that experiential learning strategies substantially enhance science subject competence among elementary students, fostering greater engagement and understanding of scientific concepts. These results advocate for the integration of experiential learning methodologies in science education, reflecting a shift away from traditional teaching practices to more effective, student-centered approaches that promote critical thinking and real-world application of knowledge.

That abortion kills someone with a right-to-life has become easier to see since Roe v. Wade. Progress in scientific research and medical practice has made both birth and viability unrealistic criteria for demarcating between human life, which demands moral respect, and merely “potential life” which does not have moral or legal equivalency with maternal interest. The near ubiquity of sonograms has probably done more than intellectual arguments to convince the public that a real baby resides in the uterus by the (...) tenth week of pregnancy. Earlier and earlier prenatal medical interventions on behalf of the unborn patient confirm this impression, and DNA indubitably substantiates that a fertilized embryo is biologically identical to the individual who is born nine months later and who has an undeniable right not to be killed.

Much of the literature directed at the Extended Mind Thesis has revolved around parity issues, focussing on the problem of how to individuate the functional roles and on the relevance of these roles for the production of human intelligent behaviour. Proponents of EMT have famously claimed that we shouldn’t take the location of a process as a reliable indicator of the mechanisms that support our cognitive behaviour. This functionalist understanding of cognition has however been challenged by opponents of EMT [such (...) as Rupert ; Adams & Aizawa ], who have claimed that differences between internal, biological processes and putatively extended ones not only exist but are actually crucial to undermine the idea that inner and outer are functionally equivalent. This debate about how to individuate the functional roles has led to a treacherous stand-off, in which proponents of EMT have been trapped under the persistent accusation of causal/constitution conflation. My strategy for responding to this charge is to look precisely at those functional differences highlighted by critics of EMT. I reckon that extended cognitive systems are endowed with quite different properties from systems that are “brain bound” and argue that it is precisely these differences that allow human minds to transcend their biological limitations. I thus defend a complementarity version of the extended mind, according to which externally located resources and internal biological elements make a different but complementary contribution to bringing about intelligent behaviour [Sutton ]. My defence of complementarity is based on both the phylogeny and the ontogeny of cognitive systems. I initially explore the interrelation between brain and cognitive development from a neuroconstructivist perspective [Quartz & Sejnowski ; Mareshal et al. ] and then argue that our brains do not have fixed functional architectures but are sculpted and given form by the activities we repeatedly engage in. As a result of repeated engagements in socio-cultural tasks, relevant brain pathways undergo substantial rewiring. Development thus scaffolds our brains, which become geared into working in symbiotic partnership with external resources. [Kiverstein & Farina ]. On these grounds, I call into question any tendency to interpret the human biological nature as fixed and endogenously pre-determined and side with proponents of DST [Oyama ; Griffiths & Gray ] and ontogenetic niche construction [Stotz ] in arguing that we should think of natural selection as operating on whole developmental systems composed of living organisms in culturally enriched niches. [Wheeler & Clark]. Complementarity defences of EMT argue that many of the kinds of cognition humans excel at can only be accomplished by brains working together with a body that directly manipulates and acts on the world [Rowlands ; Menary ]. I take Sensory Substitution Devices as my empirical case study. SSDs exploit the remarkable plasticity of our brains and with training supply a novel perceptual modality that compensates for loss or impaired sensory channel. I argue that the coupling with these devices triggers a new mode of phenomenal access to the world, something I propose to label as a kind of “artificial synaesthesia [Ward & Meijer ].This new mode of access to the world transforms our cognitive skills and gives rise to augmented processes of deep bio-technological symbiosis. SSDs therefore become mind enhancing tools [Clark ] and a perfect case study for Complementarity. Having shown the relevance of SSDs for EMT, I then take up the possibility that these devices don’t just relocate the boundaries of cognition but may also stretch the bounds of perceptual awareness. I explore the possibility that perceivers using SSDs count as extended cognitive systems and therefore argue that the experiences they enjoy should be counted as extended conscious experiences.[Kiverstein & Farina, ]. SSDs are quite often said to involve some form of incorporation.[Clark ]. Rupert has challenged this idea and its relevance for EMT on the grounds of his embedded approach. Particularly, he has explained tool-use in terms of the causal interaction between the subject and its detached tool. In the final chapter of my dissertation I critically look at his objections and argue that all his arguments fail to apply to SSDs. In SSD perception in fact the tool becomes geared to work in symbiotic partnership with the active subject and then get factored into its’ body schema so that both of them come to form a single system of cognitive analysis.

Under the WTO’s dispute settlement procedures, a party that has been injured by a scofflaw state’s failure to comply with its trade obligations may retaliate against the scofflaw state by withdrawing equivalent trade concessions. Legal and economic commentators generally view retaliation as an economically perverse strategy for enforcing freetrade norms. This Article explores an alternative explanation, arguing that retaliation may provide the optimal enforcement mechanism for trade liberalization given the prevalence of low compliance incentives and high enforcement costs in international (...) cooperation agreements. The Article argues that retaliation is superior to other remedial options because it enables an injured state to inflict maximum political costs on the scofflaw state by mobilizing powerful export groups in the scofflaw state against protectionist policies. Furthermore, this Article shows how the presence of significant protectionist groups in the injured state, which stand to benefit from retaliatory measures, also improves the injured state’s ability to commit to retaliation. Even if states have asymmetric preferences about protectionist policies, retaliation threats can still be credible since there is uncertainty about each state’s retaliation costs. Finally, the Article concludes that contrary to the conventional wisdom, the substantial role of uncertainty in this model indicates that specific performance, and not compensation, ought to be the goal of the WTO’s enforcement mechanism.

In 1992, the United States Supreme Court, in Planned Parenthood of Southeastern Pennsylvania v. Casey, upheld the ruling in Roe v. Wade, namely that women have a right “to choose to have an abortion before viability and to obtain it without undue interference from the State.”1 However, since this ruling, some states have imposed regulations that greatly limit this right by restricting access. Texas is a recent example of this. Two proposed restrictions in House Bill 2, which will be discussed (...) in detail below, will force all but eight clinics that are located in metropolitan areas to shut down. The U.S. Supreme Court put the proposed restrictions on hold in October 2014, allowing several clinics to remain open while the restrictions are being appealed in the U.S. Court of Appeals for the Fifth Circuit. If the restrictions are passed, however, those clinics will be forced to shut down and, as a result, many women in Texas will be required to travel more than 100 miles in order to access a safe and legal abortion. Much of the focus of these restrictions has been on women and rightly so. However, I want to turn the attention to physicians. The requirements exacerbate unfair treatment of abortion providers compared with other physicians. Abortion providers face threats from the public—some of which turn into violent attacks—and they are often ostracized by their fellow medical practitioners. There are so few abortion providers to begin with and the proposed requirements limit these physicians’ opportunities to practice the branch of medicine of their choosing. Although the HB 2 requirements may not result in an unconstitutional undue burden on physicians, the challenges created by the bill limit physicians’ abilities to provide abortions. As a result of these limits, HB 2 creates an unconstitutional undue burden for women seeking abortions by creating barriers directed at abortion providers and clinic staff who are willing and able to provide abortions. The first of the two controversial HB 2 requirements is the admitting privileges requirement: “A physician performing or inducing an abortion must, on the date the abortion is performed or induced, have active admitting privileges at a hospital that is located not further than 30 miles from the location at which the abortion is performed or induced.”2 The second requirement is the ambulatory surgical center requirement: “The minimum standards for an abortion facility must be equivalent to the minimum standards adopted under [Texas Health & Safety Code] [...] for ambulatory surgical centres.”3 In order to meet these state-mandated obligations, some abortion clinics would have to spend more than $1 million in upgrades if they wish to remain open. The District Court decided that the ambulatory surgical center requirement places an unconstitutional undue burden on women, and that the two requirements together place an undue burden on women in Texas and especially in the Rio Grande Valley where the nearest clinic is a couple hundred miles away.4 Later, the U.S. Court of Appeals for the Fifth Circuit reversed the District Court’s decision and argued, “the admitting privileges requirement is constitutional on its face.”5 While the regulations are being appealed, the Supreme Court granted a stay of injunction, allowing about twelve abortion clinics to reopen until a final decision regarding the regulations is made. The District Court ruled that the purpose of the two regulations was to create a substantial obstacle for women seeking abortions in Texas. While the defendants argued that the regulations were designed to make abortions safer and reduce risk, the Court decided that this was not the case. An abortion, especially a first-term abortion, is a very safe procedure and is safer than many other routine surgical procedures. As stated in Planned Parenthood v. Casey, “Unnecessary health regulations that have the purpose or effect of presenting a substantial obstacle to a woman seeking an abortion impose an undue burden on the right.”6 The undue burden in this case is imposed, not through restricting women’s access directly, but by restricting physicians’ freedom to perform abortions. The admitting privileges requirement has reduced the number of physicians who can perform abortions and the ambulatory surgical center requirement has reduced the number of clinics where abortions can be performed. The American Medical Association states, “[t]he Principles of Medical Ethics of the AMA do not prohibit a physician from performing an abortion in accordance with good medical practice and under circumstances that do not violate the law.”7 This means that physicians are not required to perform abortions, except in emergency situations, but can as long as the procedure is done safely and does not violate the law. The new Texas regulations, however, are so restrictive that few abortion providers, limited to only four urban areas, can legally perform abortions. Physicians do not have an absolute right to perform abortions as opposed to women who have an absolute right to have access to an abortion. Physicians do face many challenges that other professionals face in terms of obtaining qualifications and finding work. Abortion providers, however, face challenges that most other physicians do not. The restrictions imposed by these regulations exacerbate unfair treatment toward abortion providers and place further obstacles in their path in terms of providing the service they want and are qualified to provide. Both abortion clinics and abortion providers are being treated differently from other medical clinics and physicians. For instance, “grandfathering of existing facilities and the granting of waivers from specific requirements is prohibited for abortion providers, although other types of ambulatory surgical facilities are frequently granted waivers or are grandfathered.”8 Many abortion clinics cannot afford the necessary upgrades. Furthermore, it is extremely expensive to open a brand new clinic that complies with the ambulatory surgical center requirements. Being grandfathered in would be the only option available to abortion clinics that cannot afford the upgrade. However, unfair treatment of abortion clinics and providers is preventing those clinics from being grandfathered into the new system. As a result, many abortion clinics may be forced to close. Admitting privileges are proving difficult or impossible for physicians both to obtain and, for those who have already been granted privileges, to keep. Dr. Sherwood Lynn, an obstetrician-gynecologist who has performed abortions for decades, describes the process of obtaining admitting privileges and the difficulties abortion providers face. After sending in an application a physician must wait for the hospital to send them the required materials, “but if the address of the practice on the application is of an abortion provider or clinic, [the hospital] won’t send [them] the package of materials required. [They] simply can’t apply.”9 Dr. Lynn and several other physicians have surmised that hospitals are only withholding privileges from qualified physicians who perform abortions and that other physicians do not face this discriminatory treatment. Hospitals have also revoked privileges granted to physicians after learning that the physicians perform abortions. For instance, in Texas two doctors, “received notices [...] informing them that their admitting privileges to the University General Hospital of Dallas have been revoked, with the hospital’s CEO claiming the hospital was unaware they were providing abortion care and that the hospital believed such care would damage its reputation.”10 What is curious about this revocation is that, “federal and state laws [...] forbid hospitals from discriminating against doctors who perform abortions,” and yet hospitals are clearly doing just that.11 Dr. Pamela Richter, another abortion provider in Texas, had her temporary admitting privileges revoked with no explanation and because of this, the clinic where she performed abortions, Reproductive Services, can no longer provide abortions at all.12 As the hospital gave no reason for the revocation, it not clear Dr. Richter’s privileges were revoked because she performs abortions. Dr. Richter, however, has performed over 17,000 abortions and her privileges were revoked soon after HB 2 was introduced.13 According to the Texas Hospital Association, giving admitting privileges to doctors who do not work for the hospital is expensive and time-consuming but this does not account for the fact that hospitals are revoking previously granted privileges from physicians whom they learn are providing abortion services.14 As mentioned previously, the District Court found that the admitting privileges requirement and the ambulatory surgical center requirement do not further ensure the health and safety of women undergoing an abortion. Several physicians have testified to this fact. Dr. Lynn stated in an interview: The admitting privileges requirements are [...] absolutely unnecessary. If you have a number of patients waiting for procedures, and something happens and a patient needs to be transferred to a hospital, you’re not going to leave everyone else and go to the hospital. That makes no sense. You’re going to refer that person to a gynecologist at the hospital. There is no safety issue involved here. If a patient shows up with an emergency, every hospital is required to admit that patient. They have to by law.15 It is rare that complications will arise from an abortion performed in a clinic. Dr. Richter, for example, has performed more than 17,000 abortions and not once had to send a patient to a hospital because of complications resulting from the procedure. According to Dr. Lynn even if abortion providers were granted privileges to hospitals, it is unlikely that they will exercise them. In essence, having admitting privileges at a hospital does nothing to further ensure the safety of an already safe procedure. The only result of the admitting privileges requirement is to limit certain physicians’ ability to perform legal abortions. Not only do the HB 2 requirements fail to further ensure the health and safety of women, the HB 2 requirements may actually create more health risks to women who cannot access the eight remaining clinics. The first risk is that the remaining clinics would have an influx of patients that they may not be able to handle, forcing women to wait longer for an appointment. As stated by the District Court, “[e]ven assuming every woman in Texas who wants an abortion [...] could travel to one of the four metropolitan areas where abortions will still be available, the cumulative results of HB 2 are that, at most, eight providers would have to handle the abortion demand of the entire state.”16 Furthermore, “[t]hat the State suggests that these seven or eight providers could meet the demand of the entire state stretches credulity.”17 Abortion is a time sensitive procedure. It is safest when performed early in a pregnancy. The increase in patients to these remaining clinics, assuming all women in Texas can access them, will increase wait times and may force women to have abortions later in pregnancy. In the worst-case scenario, a woman would not see an abortion provider at all before viability. Such instances may be rare, but they are possible. In such cases, women’s access to legal abortions becomes impossible and thereby violate the ruling in Roe. Clinics may be able to avoid the aforementioned problems if they hire more physicians. However, there are two barriers to hiring more physicians. First, as mentioned previously, admitting privileges to Texas hospitals are difficult, if not impossible, for abortion providers to obtain. Second, given the negative treatment of abortion providers by anti-abortion groups, many physicians are not willing to perform abortions. The harassment abortion providers face is unique to those physicians and many physicians will not perform abortions for that reason. In an article published in the Austin Chronicle, anti- abortion activist Abby Johnson, “discusses how her group investigated appraisal district records to find the new location of where an Austin abortion physician plans to work.”18 Johnson states, “These abortionists are feeling the pressure from the pro-life movement in Texas. I think they feel like they’re on the run. And that’s how we want to keep it.”19 If the HB 2 requirements are passed and there remain at most eight abortion providers in Texas, these activists will concentrate on those clinics and, “the dangerous impact of their intimidation tactics will be exacerbated.”20 Even if the number of physicians needed to meet the demand in Texas can obtain admitting privileges and work at one of the remaining clinics, they may choose not to do such work because they are putting themselves at risk. The harm abortion providers face from such anti-abortion groups is not unique to Texas. There are stories from all over the country and from other countries where abortion is legal of physicians receiving death threats. Dr. George Tiller, an abortion provider in Kansas, was killed outside his church and had received numerous death threats prior to this. The HB 2 requirements are making it so that abortion providers either cannot provide their services any longer or will face increased threats and increased danger to themselves. Physicians are allowed to conscientiously object to providing medical interventions in certain circumstances for moral and religious reasons. However, there are limits on this right. According to the American Congress of Obstetricians and Gynecologists, “[w]hen conscientious refusals conflict with moral obligations that are central to the ethical practice of medicine, ethical care requires that the physician provide care despite reservations or that there be resources in place to allow the patient to gain access to care in the presence of conscientious refusal.”21 I would argue fear for one’s safety in the face of immediate threats is perhaps a stronger ground on which to refuse to provide care than a personal belief that abortion is immoral or against one’s religion. ACOG also states, “[p]roviders with moral or religious objections should either practice in proximity to individuals who do not share their views or ensure that referral processes are in place so that patients have access to the service that the physician does not wish to provide.”22 This responsibility has been largely disputed by the medical community but in cases of rape, incest, and health risks to women, referrals must be made without exception. However, under the requirements of HB 2, working in proximity to an abortion provider may not be possible because they are so geographically limited. Referrals are supposed to be made within reason. Some areas of Texas, such as the Rio Grande Valley, are up to 200 miles away from the nearest clinic that would remain open if HB 2 is passed. Referrals may simply not be feasible given the geographical distances and the decreasing number of available physicians. As mentioned above, there are two risks to the health and safety of women as a result of HB 2. The second of these is that if a woman cannot access one of the remaining clinics, she may seek out a more convenient but illegal and unsafe abortion, which is far more likely to result in a dangerous complication. Dr. Lynn states, “[b]ecause of the restrictions lawmakers impose, women will seek abortions illegally, and we’re going to see a rise in septic abortions.”23 Some areas of Texas might effectively revert back to a pre-Roe era where abortions were performed in unsanitary conditions by unqualified people resulting in dangerous medical complications far more often than legal abortion procedures do now. Physicians like Dr. Lynn who want to prevent this from happening generally cannot do so without facing legal sanction. Physicians have a duty to provide safe medical care and if they cannot obtain admitting privileges, they cannot exercise this duty. ACOG released a statement expressing their objections to the new requirements. They state that HB 2 is, “plainly intended to restrict the reproductive rights of women in Texas through a series of requirements that improperly regulate medical practice and interfere with the patient-physician relationship.”24 Executive Vice-President of ACOG, Hal C. Lawrence III stated: The Texas bills set a dangerous precedent of a legislature telling doctors how to practice medicine and how to care for individual patients. ACOG opposes legislative interference, and strongly believes that decisions about medical care must be based on scientific evidence and made by licensed medical professionals, not the state or federal government.25 Abortion is one of only a few areas of medicine where the legislature imposes so many regulations restricting particular physicians’ ability to practice medicine. Not only are abortions providers being regulated by the state, they are also facing clear discrimination from others within the medical community. The state is closing down clinics that do not meet the ambulatory surgical center requirements and hospitals are denying physicians admitting privileges because they perform abortions. In summary, abortion providers are being discriminated against both by the legislature and other members of the medical community. Other physicians who do not perform abortions are not denied admitting privileges on discriminatory grounds. Clinics that cannot afford upgrades to become an ambulatory surgical center are being grandfathered in, while abortion clinics are being forced to close down. Ob-Gyns who conscientiously object to performing abortions and who are not located in close proximity to at least one abortion provider cannot effectively fulfill their duty to refer patients. Lastly, given the barriers these regulations will create, there will likely be a rise in complications resulting from abortions provided under grossly unsafe conditions. Physicians, whose duty it is to provide safe and effective medical care, are being denied the right to exercise this duty. While this denial may not be unconstitutional, it is certainly unjust and discriminatory and creates obstacles that other physicians do not face. Most importantly, these obstacles are creating an undue burden for women. The HB 2 requirements do not increase the health and safety of abortions; all they do is create substantial obstacles for women. In light of these observations, the requirements seem to me to be in clear violation of Casey, in which it was decided that, “[u]nnecessary health regulations that have the purpose or effect of presenting a substantial obstacle to a woman seeking an abortion impose an undue burden on that right.”26 These regulations do just what Casey was meant to prohibit and this is accomplished through limiting physicians’ ability to practice safe abortions across the state of Texas. Therefore, the HB 2 requirements may not impose an undue burden on doctors but they do impose an undue burden on women. PDF available: Rachel Hill, "Texas HB 2," Voices in Bioethics.

Original and cumulative prospect theory differ in the composition rule used to combine the probability weighting function and the value function. We test the predictive power of these composition rules by performing a novel out-of-sample prediction test. We apply estimates of prospect theory’s weighting and value function obtained from two-outcome cash equivalents, a domain where original and cumulative prospect theory coincide, to three-outcome cash equivalents, a domain where the composition rules of the two theories differ. Although both forms of prospect (...) theory predict three-outcome cash equivalents very well, at the aggregate level, we find small but systematic under-prediction of cash equivalents for cumulative prospect theory and small but systematic over-prediction of cash equivalents for original prospect theory. We also observe substantial heterogeneity across subjects and types of gambles, some of which is accounted for by differences in the curvature and elevation of the weighting function across individuals. We also find differences in prediction related to whether the worst outcome is zero or non-zero. (shrink)

Wenn eine Person unter einer tödlichen Krankheit leidet und nicht über die Ressourcen für eine medizinische Behandlung verfügt, sind wir normalerweise dazu verpflichtet, ihr die notwendigen Ressourcen bereitzustellen. Wären wir aber in einem biotechnischen Zukunftsszenario, in dem die menschliche Lebensspanne durch Eingriffe in den Alterungsprozess erhöht werden kann, auch dazu verpflichtet, anderen Personen die notwendigen Ressourcen für solche Maßnahmen bereitzustellen? John Harris hat argumentiert, dass wir zu solch einer direkten biotechnischen Lebensverlängerung verpflichtet wären, da ein Leben zu verlängern das Gleiche (...) sei, wie ein Leben zu retten. Im vorliegenden Aufsatz wird gezeigt, dass Harris’ Argument nicht schlüssig ist, da entgegen seiner Prämisse ein begrifflicher Unterschied zwischen der Rettung und der Verlängerung eines Lebens besteht. Auf Grundlage von Harris’ zurückgewiesenem Argument werden dann aber zwei alternative Argumente für eine (prima facie) Pflicht zur direkten Lebensverlängerung konstruiert. Das erste Argument basiert auf der Überlegung, dass durch eine direkte biotechnische Lebensverlängerung trotz des begrifflichen Unterschieds mit einer substanziellen Wahrscheinlichkeit Leben gerettet werden würden. Das zweite Argument besagt, dass trotz deskriptiver Unterschiede eine moralische Äquivalenz zwischen der Rettung und der Verlängerung eines Lebens besteht, sofern durch die bloße Lebensverlängerung das Leben um die gleiche Dauer und Qualität verlängert wird wie durch die Lebensrettung. ---------------------------------------------------------------------------------------------------- ---------------------------------------------------------------------------------- When a person suffers from a deadly disease and is lacking the resources for a medical treatment, we are normally obliged to provide the necessary resources. But would we also be morally obliged to provide the resources for an extension of someone’s lifespan through anti-aging treatments which might be developed due to biotechnological progress? John Harris has argued that there would be an obligation to such a direct biotechnical life extension because extending a life is the same as saving a life. In the present paper, it will be shown that Harris’ argument is not sound since, contrary to his premise, there is a conceptual difference between extending and saving a life. On the basis of Harris’ rejected argument, though, two alternative arguments for a (prima facie) obligation to direct biotechnical life extension will be developed. The first argument is based on the idea that, despite the conceptual difference, one saves someone’s life with a substantial probability when extending it by direct biotechnical means. In the second argument, it will be argued that there is a moral equivalence between extending and saving someone’s life despite the descriptive differences as far as the additional lifetime has the same duration and quality in both cases.

In response to Korn, Huelsman, and Reed's (1992)question, "Who defines those interests, and how serious must the setback be?" (p. 126), we argue that a wrongful (unjust) harm (a setback of interest) is not equivalent to a hurt (a temporary distressing mental state) and that the interests of importance are welfare interests (general means to our ulterior aims), not just a desire to avoid unpleasant mental states (hurts). To set back a welfare interest is to reverse its course or to (...) impede, thwart, defeat, or doom it. It is the primary responsibility of the investigator to define both welfare interests and the risk of harm. An informed consent - one with substantial understanding, in substantial absence of control by others, and given intentionally - allows participants to autonomously authorize participation in research, including their toleration of acts of mental discomfort or distress during an experiment. Not only were our participants not wrongfully harmed, they benefited and were willing to volunteer for future research. No strong evidence has been advanced or linked to guided imagery in a way that would justify its restraint; to so claim evokes a standard of legal paternalism that fails to respect participants' competence and autonomy to choose to participate in research on rape using guided imagery.
