One of the widespread confusions concerning the history of the 1887 Michelson-Morley experiment has to do with the initial explanation of this celebrated null result due independently to FitzGerald and Lorentz. In neither case was a strict, longitudinal length contraction hypothesis invoked, as is commonly supposed. Lorentz postulated, particularly in 1895, any one of a certain family of possible deformation effects for rigid bodies in motion, including purely transverse alteration, and expansion as well as contraction; FitzGerald may well have had (...) the same family in mind. A careful analysis of the Michelson-Morley experiment (which reveals a number of serious inadequacies in many text-book treatments) indeed shows that strict contraction is not required. (shrink)

Motivated by the increasing economic significance of investment advisory industries and the prevalence of wrongdoing in financial planning services, we examine whether, and to what extent, employee misconduct is shaped by their local corruption culture. Using novel data of more than 4.7 million adviser-year observations of financial advisers and the Department of Justice’s data on corruption, we find that financial advisers and advisory firms located in areas with higher levels of corruption are more likely to commit misconduct. These results hold (...) for both individual advisor and firm level analyses and are robust to the use of various fixed effects, model specifications, proxies for corruption and misconduct, and an instrumental variable approach. Using the passage of the Dodd-Frank Whistleblower Provision, which provides incentives for reporting corruption incidences and thereby reduces the incentives for fraud, we find that the relation between local corruption culture and adviser misconduct is attenuated after the provision enacted by the SEC. Overall, our study highlights the externalities of corruption culture on individual ethics and the essential role of whistleblowing laws in reducing corruption-prone norms. (shrink)

Certainty (and the lack thereof) is a major issue in mathematics and computer science. Mathematicians strongly believe in a special kind of certainty for their theorems.

We give a consistency proof within a weak fragment of arithmetic of elementary algebra and geometry. For this purpose, we use EFA (exponential function arithmetic), and various first order theories of algebraically closed fields and real closed fields.

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)

We have been recently engaged in this search, and have announced a long series of successively simpler and more convincing examples. See [Fr09-10].

Clinical experience suggests that adult survivors of childhood trauma arrive at their memories in a number of ways, with varying degrees of associated distress and uncertainty and, in some cases, after memory lapses of varying duration and extent. Among those patients who enter psychotherapy as a result of early abuse, three general patterns of traumatic recall are identified: relatively continuous and complete recall of childhood abuse experiences coupled with changing interpretations of these experiences, partial amnesia for abuse events, accompanied by (...) a mixture of delayed recall and delayed understanding, and delayed recall following a period of profound and pervasive amnesia. These patterns are represented by three composite clinical vignettes. Variations among them suggest that the phenomena underlying traumatic recall are continuous not dichotomous. Future research into the nature of traumatic memory should be informed by clinical observation. (shrink)

Following an earlier paper in the journal in which Evans argued that it was commercial exploitation, not mere payment, that was morally objectionable about certain sorts of organ donation, this paper looks at the moral issues when commercial exploitation is eliminated from systems of paid organ donation. It argues that there are no conclusive moral arguments against such schemes for non-exploitative paid kidney donation.

The goal is to show that various exotic prefix classes can be "tamed by large cardinals". I.e., every statement in the class is either provable or refutable using presently formulated large cardinals. Some of these exotic prefix classes consist entirely of explicitly P01 sentences.

Corporate responsibility, governance and business ethics are 'leading edge' issues in contemporary management. Their recent origins are in the concern about the social legitimacy of the corporation, the rights of stakeholders versus shareholders, and specific developments including consumerism, environmentalism and the management search for quality and excellence. The book focuses on practical issues, with illustrations and mini-cases. It provides an effective introduction to ethical concepts and their applications for the student or professional manager.

We present some new set and class theoretic independence results from ZFC and NBGC that are particularly simple and close to the primitives of membership and equality. They are shown to be equivalent to familiar small large cardinal hypotheses. We modify these independendent statements in order to give an example of a sentence in set theory with 5 quantifiers which is independent of ZFC. It is known that all 3 quantifier sentences are decided in a weak fragment of ZF without (...) power set. (shrink)

Gerald Doppelt's recent ?Kuhn's Epistemological Relativism: An Interpretation and Defense? (Inquiry, Vol. 21 [1978], pp. 33?86) offers a reconstruction of Thomas Kuhn's views concerning theory choice in science in which Kuhn's ?incommensurability thesis?, and his epistemological relativism, are defended. It is argued that Doppelt's reconstruction fails to provide an adequate defense, and that both Kuhn's incommensurability thesis, and his epistemological relativism, as reconstructed by Doppelt, remain philosophically unacceptable.

All axiomatizations in sections 1,2,4-8 are in the language L(Î,W) with just Î and the constant symbol W standing for a Subworld. Think of W as yesterday's world, and think of the quantifiers in the theory as ranging over today's world. The philosophy is that since the universe cannot be completed, every time we reflect on the universe and what we have reflected on previously, we obtain a larger universe.

This paper critiques the standard translation of ariya-sacca as ‘Noble Truth’ and argues that the term refers to four saccas as ‘true realities’, rather than as verbalised ‘truths’ about these realities; the teachings about them are not, as such what the term ariya-sacca refers to. Moreover, only one of the ariya-saccas is itself ever described in the suttas as ‘noble’. The four are ‘true realities for the spiritually ennobled’: the fundamental, basic, most significant genuine realities that the Buddha and other (...) noble ones see in the flow of experience of themselves and/or others. The first of them is not best translated as ‘suffering’ but as ‘pain’ – in all its many senses – or indeed ‘the painful’: the up?d?na-kkhandhas as ‘bundles of grasping-fuel’ which are described, adjectivally, as ‘painful’. The paper includes a new translation of the Dhamma-cakka-ppavattana Sutta in line with this analysis. (shrink)

This paper examines one approach to the ethics of companion animals, which emerges from the dominant historical tradition and is increasingly familiar in everyday life as well as in work on companion animals in the social sciences. I label it the “utilization with welfare-safeguards” model, or, more gently worded, “seeking benefits while ensuring welfare.” Some of the “benefits” considered are complex ones (like guiding the sight impaired) and others simpler (like reducing stress or providing affection). I explore several problems involved (...) in this approach (including the sometimes jarring inappropriateness of “benefit” terminology). I then offer an alternative account where the primary moral obligation toward companion animals is to develop, nurture, respect, and protect the loving relationship between them and their human companions, since thriving in such a relationship, I claim, has become part of their evolved telos (to use Bernard Rollin’s term)or evolved nature. This priority naturally leads to ensuring welfare, but the highly pro-active approach involved takes the obligation beyond standard welfare provision and “TLC” (“tender loving care”). Some implications of this position are explored. (shrink)

This study applies the concept of intersectionality to Black women's entrepreneurial activity. Specifically, the author addresses the ways in which race, gender, and class intersect to inform working-class Black women's decisions and experiences as hair salon owners. By placing Black women at the center of analysis, the author explores business ownership from the perspective of a group that has frequently been overlooked in sociology of entrepreneurship research. The findings indicate that race, gender, and class inequalities shape working-class Black women's entrepreneurship (...) in two areas: the process of becoming entrepreneurs and relationships with stylists.

AT the conclusion of his recently published paper on Corinna1 Professor Page leaves open the question whether the poetess was a contemporary of Pindar or of Moschus-whether she belongs to the middle of the fifth century or the end of the third. He gives excellent reasons for believing that these two dates exhaust the possibilities: they are far more probable than a date either outside or between them; but there seems to be no sure criterion by which we can decide (...) between the two, and Professor Page has to end his researches with a suspension of judgement.

We present a range of mathematical theorems whose proofs require unexpectedly strong logical methods, which in some cases go well beyond the usual axioms for mathematics.

In recent decades governments around the world have been increasingly concerned about terrorism and have introduced new laws and policies in an attempt to combat it. I examine here the weakest link in chains of security management: what I call the realm of “the informal,” where neither law nor formal policy is at work, but where stereotypes, traditional sayings and jokes, social ideals often promoted by mass media, etiquette requirements certainly are. This realm is so dangerous precisely because of its (...) deceptively innocuous appearance. First, I explain the kinds of things that function in the informal realm, revealing that it is more extensive than might first appear. Secondly, I describe three real-life examples where some informal factor plays a vital role in a catastrophic outcome, to show that such seemingly trivial matters can acquire tremendous practical significance in critical situations. My focus is on the influence of some informal factor on individuals who are in no way trying to threaten security, but rather intend to maintain or enhance it. Their roles call for that commitment. Finally I consider one of the three examples more carefully and illustratively, to demonstrate some of the key points raised. Currently, thinking about the dangers informal factors pose is routinely reactive (rather than proactive), often prompted by a catastrophe that has already occurred, but this means we miss some of what could be learned from the catastrophe. We need a far more proactive approach to those factors in the informal sphere and we need a much stronger focus on individuals who are responsible for and committed to maintaining security. Otherwise threats to security will remain are more serious than is typically acknowledged. (shrink)

The food-energy-climate change trilemma refers to the stark alternatives presented by the need to feed a world population growing to nine billion, the attendant risks of land conversion and use for global climate change, and the way these are interconnected with the energy crisis arising from the depletion of oil. Theorizing the interactions between political economies and their related natural environments, in terms of both finitudes of resources and generation of greenhouse gases, presents a major challenge to social sciences. Approaches (...) from classical political economy, transition theory, economic geography, and political ecology, are reviewed before elaborating the neo-Polanyian approach adopted here. The case of Brazil, analysed with an `instituted economic process’ framework, demonstrates how the trilemma is a spatial and historical socio-economic phenomenon, varying significantly in its dynamics in different environmental and resource contexts. The paper concludes by highlighting challenges to developing a social scientific theory in this field. (shrink)

Tversky and Kahneman (1974) originally discussed three main heuristics: availability, representativeness, and anchoring-and-adjustment. Research on judgemental forecasting suggests that the type of information on which forecasts are based is the primary factor determining the type of heuristic that people use to make their predictions. Specifically, availability is used when forecasts are based on information held in memory; representativeness is important when the value of one variable is forecast from explicit information about the value of another variable; and anchoring-and-adjustment is employed (...) when the value of a variable is forecast from explicit information about previous values of that same variable. Although there has been increased emphasis on the adaptiveness of heuristics and increased interest in specifying their use in terms of computational models, this way of structuring our knowledge about judgemental forecasting continues to be a useful one. I use it to frame discussion of some recent debates in the area. (shrink)

The quantum theory of de Broglie and Bohm solves the measurement problem, but the hypothetical corpuscles play no role in the argument. The solution finds a more natural home in the Everett interpretation.

We focus on two formal methods contexts which generate investigations into decision problems for finite strings.

I make three points. First, processors and depletable resources should not be regarded as alternative means of processing information: they are both necessary. Second, comparing a processor account with a rational allocation mechanism to a depletable-resources account without one is not a fair comparison. Third, depletable resources can act as signals as well as fuels.

Early Syriac Christianity presents two notable paradigms for understanding liturgy as a means for the ethical formation of the congregation. Ephrem the Syrian (d. 373) in his hymns for the Nativity vigil, and Jacob of Sarug (d. 521) in his verse homilies, each addressed their congregations in ways that utilized ritual participation in the liturgy for ethical and moral cultivation. Ephrem sought to instill his congregation with a biblical and theological understanding of the Nativity that would yield ethical enactment in (...) the world. Jacob worked to use the experience of liturgical participation to mold the Christian’s moral disposition. For both, God’s salvation enabled the healing of the human condition in its various dimensions: physical, social, ecclesial. Liturgy as disciplined ritual activity provided the tools by which their congregations could learn, experience, and enact that healing. (shrink)

This paper looks at some of the missiological implications of the history, presence and ministry of diaspora Christians in Singapore and Malaysia in the 19th and early 20th century. More particularly, it considers how their lives and legacy tied together Europe, China and Southeast Asia in mission. It suggests that the global movement of people, ideas and faith is not new, but has ridden the waves of globalization for centuries if not millennia.

Atran & Norenzayan (A&N) survey a substantial body of theory and evidence on which there is broad agreement in the cognitive science of religion. Some parts of their argument (for instance, concerning the causes of costly commitment to religious beliefs) are more speculative and remain a focus of lively debate and further research.

Theories and Methods is the one compulsory unit on the AEB and Interboard syllabuses. This guide outlines the main sociological perspectives, and discusses three main approaches: positivism, phenomenology and critical social research. The topic-book format should be suitable for linear and modular courses, and there are sample questions and skills advice.

In this paper we report a study of the approach of six U.K. water and electricity companies towards managing the relationship with their ''green'' stakeholders. Stakeholders are accorded increasing importance in political discourse and stakeholder theory is emerging as a promising framework for the analysis of corporate social performance.We studied the companies'' general approach towards green stakeholders, their dealings with specific stakeholder groups and whether they emphasised the consultation or the information aspect of stakeholder management. We found that none of (...) the six companies had a systematic stakeholder approach that extended to all potential green stakeholders. Rather, the importance of specific stakeholder groups seemed to be determined by managers'' intuition and by the stance that the stakeholders themselves displayed towards the company. (shrink)
