This article deals with the question of what time reversal means. It begins with a presentation of the standard account of time reversal, with plenty of examples, followed by a popular non-standard account. I argue that, in spite of recent commentary to the contrary, the standard approach to the meaning of time reversal is the only one that is philosophically and physically viable. The article concludes with a few open research problems about time reversal.

We present a precise form of structural realism, called group structural realism , which identifies ‘structure’ in quantum theory with symmetry groups. However, working out the details of this view actually illuminates a major problem for structural realism; namely, a structure can itself have structure. This article argues that, once a precise characterization of structure is given, the ‘metaphysical hierarchy’ on which group structural realism rests is overly extravagant and ultimately unmotivated.

Why is gauge symmetry so important in modern physics, given that one must eliminate it when interpreting what the theory represents? In this paper we discuss the sense in which gauge symmetry can be fruitfully applied to constrain the space of possible dynamical models in such a way that forces and charges are appropriately coupled. We review the most well-known application of this kind, known as the 'gauge argument' or 'gauge principle', discuss its difficulties, and then reconstruct the gauge argument (...) as a valid theorem in quantum theory. We then present what we take to be a better and more general gauge argument, based on Noether's second theorem in classical Lagrangian field theory, and argue that this provides a more appropriate framework for understanding how gauge symmetry helps to constrain the dynamics of physical theories.

Many have suggested that the transformation standardly referred to as `time reversal' in quantum theory is not deserving of the name. I argue on the contrary that the standard definition is perfectly appropriate, and is indeed forced by basic considerations about the nature of time in the quantum formalism.

In this paper, we explore the impact of individualism and collectivism on three basic aspects of ethical decision making - the perception of moral problems, moral reasoning, and behavior. We argue that the inclusion of business practices within the moral domain by the individual depends partly upon individualism and collectivism. We also propose a pluralistic approach to post-conventional moral judgment that includes developmental paths appropriate for individualist and collectivist cultures. Finally, we argue that the link between moral judgment and behavior (...) is related to individualism and collectivism. (shrink)

This paper examines the impact of the level of economic development, income inequality, and five cultural variables on the rate of software piracy at the country level. The study finds that software piracy is significantly correlated to GNP per capita, income inequality, and individualism. Implications for anti-piracy programs and suggestions for future research are developed.

I propose a general geometric framework in which to discuss the existence of time observables. This framework allows one to describe a local sense in which time observables always exist, and a global sense in which they can sometimes exist subject to a restriction on the vector fields that they generate. Pauli׳s prohibition on quantum time observables is derived as a corollary to this result. I will then discuss how time observables can be regained in modest extensions of quantum theory (...) beyond its standard formulation. (shrink)

'The arrow of time' refers to the curious asymmetry that distinguishes the future from the past. Reversing the Arrow of Time argues that there is an intimate link between the symmetries of 'time itself' and time reversal symmetry in physical theories, which has wide-ranging implications for both physics and its philosophy. This link helps to clarify how we can learn about the symmetries of our world, how to understand the relationship between symmetries and what is real, and how to overcome (...) pervasive illusions about the direction of time. Roberts explains the significance of time reversal in a way that intertwines physics and philosophy, to establish what the arrow of time means and how we can come to know it. This book is both mathematically and philosophically rigorous yet remains accessible to advanced undergraduates in physics and the philosophy of physics. This title is also available as Open Access on Cambridge Core. (shrink)

Pierre Curie claimed that a symmetry of a cause must be found in the produced effects. This paper shows why this principle works in Curie’s example of the electrostatics of central fields, but fails in many others. The failure of Curie’s claim is then shown to be of special empirical interest, in that this failure underpins the experimental discovery of parity violation and of CP violation in the twentieth century.

Leibniz Equivalence is a principle of applied mathematics that is widely assumed in both general relativity textbooks and in the philosophical literature on Einstein’s hole argument. In this article, I clarify an ambiguity in the statement of this Leibniz Equivalence, and argue that the relevant expression of it for the hole argument is strictly false. I then show that the hole argument still succeeds as a refutation of manifold substantivalism; however, recent proposals that the hole argument is undermined by principles (...) of representational equivalence do not fare so well.

The relationship of corporate social responsibility to risk management has been treated sporadically in the business society literature. Using real options theory, I develop the notion of corporate social responsibility as a real option its implications for risk management. Real options theory allows for a strategic view of corporate social responsibility. Specifically, real options theory suggests that corporate social responsibility should be negatively related to the firm’s ex ante downside business risk.

Integrative social contracts theory (ISCT) uses empirical methods to develop guidelines for international business ethics. This article criticizes ISCT in terms of the way people actually think about contracts and agreements around the globe. Differences in orientations to communications context, moral reasoning, and institutional and structural conditions make the identification of authentic norms, hypernorms, and relevant communities problematic. The difficulties of the empirical methods suggest recourse to more traditional theoretical approaches for the identification of hypernorms as well as a stronger (...) test for the compatibility of authentic norms with hypernorms.

Business and society research has increasingly moved from the margins to the mainstream. Although this progression has benefited from advances in empirical research, the field continues to suffer from considerable methodological challenges that hamper its development. In this introductory article to the special issue, we review how far our field has come in advancing methods and methodologies in business and society research. We also highlight the methods and methodologies covered by the contributors to this special issue and how they help (...) address key shortcomings in our field. Finally, we suggest some promising research methodologies that can address important business and society research challenges going forward. (shrink)

Increasingly research in the field of business and society suggests that ethics and corporate social responsibility can be profitable. Yet this work raises a troubling question: Is it ethical to use ethics and social responsibility in a strategic way? Is it possible to be ethical or socially responsible for the wrong reason? In this article, we define a strategy concept in order to situate the different approaches to the strategic use of ethics and social responsibility found in the current literature. (...) We then analyze the ethics of such approaches using both utilitarianism and deontology and end by defining limits to the strategic use of ethics. (shrink)

This paper is a tour of how the laws of nature can distinguish between the past and the future, or be T-violating. I argue that, in terms of the basic argumentative structure, there are basically just three approaches currently being explored. The first is an application of Curie's Principle, together with the CPT theorem. The second route makes use of a principle due to Pasha Kabir which allows for a direct detection. The third route makes use of a Non-degeneracy Principle, (...) and is related to the energy spectrum of elementary particles. I show how each provides a general template for detecting T-violation, illustrate each with an example, and discuss their prospects in extensions of particle physics beyond the standard model.

Ashtekar has illustrated that two of the available roads to testing for time asymmetry can be generalized beyond the structure of quantum theory, to much more general formulations of mechanics. The purpose of this note is to show that a third road to T-violation, which I have called "Wigner's Principle," can be generalized in this way as well.

Abstract:This article defines and analyzes the nature of a trust relation. It specifically examines the internal and external morality of trust relations and the ethical limits of those relations. It examines both the ends pursued by trust relations as well as the means by which trust is developed. It shows that the ends need to be evaluated by traditional ethical theories, while the ethical constraints of the trust process depend upon the specific bases of trust. In addition, the consequences of (...) the trust process differ in their impact on the trustor and third parties. Despite the popularity of trust in the literature, this study recommends caution in the use of trust as an ethical basis for economic organization. The optimal form of trust, although still subject to limitations, is fairness-based trust. (shrink)

I point out that some common folk wisdom about time reversal invariance in classical mechanics is strictly incorrect, by showing some explicit examples in which classical time reversal invariance fails, even among conservative systems. I then show that there is nevertheless a broad class of familiar classical systems that are time reversal invariant.

I point out a simple sense in which the standard formulation of Curie’s principle is false when the symmetry transformation it describes is time reversal.

How should we characterise the observable aspects of quantum theory? This paper argues that philosophers and physicists should jettison a standard dogma: that observables must be represented by self-adjoint or Hermitian operators. Four classes of non-standard observables are identified: normal operators, symmetric operators, real-spectrum operators, and none of these. The philosophical and physical implications of each are explored.

This paper views corruption as a form of contracting amenable to analysis from the viewpoint of transaction-cost economics. Concepts such as transaction, bounded rationality, opportunism, and asset specificity are shown to apply to cases of corruption. Both market and parochial corruption are hypothesized to vary in accordance with changes in the specificity of assets invested to support the corruption transaction. Evidence from a number of different studies tends to support the hypothesized relation. The implications of the transaction-cost perspective are developed (...) for policy makers and directions for future research are suggested. (shrink)

In this article, we examine the relationship of the multinational firm’s market environment, stakeholders, resources, and values to the development of strategic social planning and strategic social positioning. Using a sample of multinational enterprises in Mexico, we examine the relationship of these different ways of conducting social strategy to the creation of value by the firm. The market conditions of munificence and dynamism, and the resource for continuous innovation are found to be related to strategic social positioning. The social responsibility (...) orientation of the firm is related to strategic social planning. Positioning is related to value creation for the multinational firm, but planning is not. We discuss the implications of these findings for research and practice. (shrink)

ABSTRACT:The history of the practice of corporate social responsibility has largely been limited to the twentieth century, with a focus on the United States. This paper provides a brief introduction to CSR practice from the nineteenth century through World War I in the United Kingdom, United States, Japan, India, and Germany. The relevance of nineteenth-century CSR to current debates and research regarding the motivations for CSR, the business cases for CSR, stakeholder management, political CSR, industry self-regulation, and income inequality are (...) also discussed.

Jim Weatherall has suggested that Einstein's hole argument, as presented by Earman and Norton, is based on a misleading use of mathematics. I argue on the contrary that Weatherall demands an implausible restriction on how mathematics is used. The hole argument, on the other hand, is in no new danger at all.

Despite the appeal of the stakeholder concept, little work had been done with respect to the development of specific structures for the management of stakeholder relations. This paper draws upon the organizational justice literature to demonstrate how many of its concerns coincide with those of the stakeholder management literature. It shows that organizational justice can provide specific advice for the design of stakeholder relations, while stakeholder theory can broaden the scope of current inquiries into organizational justice.

Considering the urgency of addressing grand challenges that affect human health and achieving the ambitious health targets set by the United Nations’ Sustainable Development Goals, the role of business in improving health has become critical. Yet, our systematic review of the business–health literature reveals that business research focuses primarily on occupational health and safety, health care organizations, and health regulations. To embrace the health externalities generated by business activities, we propose that future research should investigate the conditions under which business (...) articulates and participates in health challenges, engages in multilevel actions toward tackling health challenges, and improves health outcomes and its impact on the health of external stakeholders, including customers and local communities. We also urge business scholars to engage with the public health research community to increase impact. (shrink)

Wigner gave a well-known proof of Kramers degeneracy, for time reversal invariant systems containing an odd number of half-integer spin particles. But Wigner's proof relies on the assumption that the Hamiltonian has an eigenvector, and thus does not apply to many quantum systems of physical interest. This note illustrates an algebraic way to talk about Kramers degeneracy that does not appeal to eigenvectors, and provides a derivation of Kramers degeneracy in this more general context.

This dissertation is about the sense in which the laws of quantum theory distinguish between the past and the future. I begin with an account of what it means for quantum theory to make such a distinction, by providing a novel derivation of the meaning of "time reversal." I then show that if Galilei invariant quantum theory does distinguish a preferred direction in time, then this has consequences for the ontology of the theory. In particular, it requires matter to admit (...) "internal" degrees of freedom, in that the position observable generates a maximal abelian algebra. I proceed to show that this is not a purely quantum phenomenon, but can be expressed in classical mechanics as well. I then illustrate three routes for generating quantum systems that distinguish a preferred temporal direction in this way. (shrink)

This paper analyzes the likelihood that recent conventions against corruption signed by the OECD and the OAS will be effective in Latin America. It begins by looking at the cultural context of corruption in Latin America and examines efforts by Latin American signatories to implement both agreements. It then evaluates the extent to which these efforts will prove successful. It concludes with suggestions for the development of culturally sensitive policies that will be effective in the fight against corruption in Latin (...) America. (shrink)

Rollo Handy's recent discussion of “Personality Factors and Intellectual Production” is interesting and timely. It seems to me that one of the things he is saying is that, since we lack objective criteria for the evaluation of the various philosophies, we may be forced, reluctantly, to judge them, at least partially, on the basis of what type of person produced them. “But since we do not have generally accepted criteria for the worth of philosophic endeavors … we should at least (...) become aware of the possible personality determinants of one's attitude toward philosophy. If certain distinguished philosophers, appearing in a psychological clinic, would be diagnosed as having severe personality disturbances, this is something we should know. The psychologists may be wrong, but then again they may be right. To say that this has no relevance at all to the worth of the philosopher's views seems ostrich-like.”. (shrink)

This special issue of Foundations of Physics collects together articles representing some recent new perspectives on the hole argument in the history and philosophy of physics. Our task here is to introduce those new perspectives.

This qualitative study looks at the complex relationship of transaction costs, norms, and social networks through a comparison of industrial buyer-seller relationships in the United States and Mexico. Despite arguments by transactioncost theorists that the nature of cooperation in business is largely a function of the nature of investments in transaction assets, this article illustrates several cases where the economic logic is attenuated and a mutual orientation develops as the social structure promotes greater trust either because of shared norms or (...) network ties. It also suggests that asset specificity may at times be a product of the social structure in which the transaction is embedded. The article develops theoretical propositions and suggests directions for future research. (shrink)

In this book, Bryan W. Van Norden examines early Confucianism as a form of virtue ethics and Mohism, an anti-Confucian movement, as a version of consequentialism. The philosophical methodology is analytic, in that the emphasis is on clear exegesis of the texts and a critical examination of the philosophical arguments proposed by each side. Van Norden shows that Confucianism, while similar to Aristotelianism in being a form of virtue ethics, offers different conceptions of “the good life,” the virtues, human (...) nature, and ethical cultivation.

This paper introduces a little-known episode in the history of physics, in which a mathematical proof by Pierre Fermat vindicated Galileo’s characterization of freefall. The first part of the paper reviews the historical context leading up to Fermat’s proof. The second part illustrates how a physical and a mathematical insight enabled Fermat’s result, and that a simple modification would satisfy any of Fermat’s critics. The result is an illustration of how a purely theoretical argument can settle an apparently empirical debate.

In this contribution in honour of Paul Busch, we criticise the claims of many expositions that the time-energy uncertainty principle allows both a violation of energy conservation and particle creation, provided that this happens for a sufficiently short time. But we agree that there are grains of truth in these claims: which we make precise and justify using perturbation theory.

This note argues that quantum observables can include not just self-adjoint operators, but any member of the class of normal operators, including those with non-real eigenvalues. Concrete experiments, statistics, and symmetries are all expressed in this more general context. However, this more general class of observables also introduces a new restriction on which sets of operators can be interpreted as observables at once. These sets are referred to here as 'sharp sets.

This paper looks broadly at the theme of corporate governance in Mexico. It begins with a brief analysis of the historical corporate governance model in Mexico, including the governance structures, the banking and financial systems, ownership and control patterns, industrial policy, and industrial relations. The paper then examines how and why these various aspects of corporate governance have been changing with processes of economic liberalization currently under way. Finally, it analyzes the consequences of changes in the model of corporate governance (...) for the country's development (e.g. increased consumer goods for middle class consumers, increased disclosure by domestic corporations, less support for corporate social programs, etc.).

It’s often been thought that Curie’s principle says something that’s just obviously true about the world. However, Bryan Roberts has discovered a simple way in which Curie’s principle fails.
