We present a new class of models of players’ reasoning in non-cooperative games, inspired by David Lewis's account of common knowledge. We argue that the models in this class formalize common knowledge of rationality in a way that is distinctive, in virtue of modelling steps of reasoning; and attractive, in virtue of being able to represent coherently common knowledge of any consistent standard of individual decision-theoretic rationality. We contrast our approach with that of Robert Aumann, arguing that the former avoids (...) and diagnoses certain paradoxes to which the latter may give rise when extended in particular ways. (shrink)

David Lewis is widely credited with the first formulation of common knowledge and the first rigorous analysis of convention. However, common knowledge and convention entered mainstream game theory only when they were formulated, later and independently, by other theorists. As a result, some of the most distinctive and valuable features of Lewis' game theory have been overlooked. We re-examine this theory by reconstructing key parts in a more formal way, extending it, and showing how it differs from more recent game (...) theory. In contrast to current theories of common knowledge, Lewis' theory is based on an explicit analysis of the modes of reasoning that are accessible to rational individuals and so can be used to analyse the genesis of common knowledge. Lewis' analysis of convention emphasises the role of inductive reasoning and of salience in the maintenance of conventions over time.

In this paper, I address two connected issues that arise when one considers a rational agent facing a decision problem. One is whether or not the agent may find that the dictates of rationality are such that they cannot all be followed. For example, one may ask whether or not the requirements on the agent's actions imposed by rationality can conflict in an irreconcilable way, making it impossible to satisfy all of them. Put differently, one may ask whether or not (...) any apparent conflict of this type must in fact be capable of rational resolution. I shall say that an agent who is in a position in which the requirements of rationality cannot all be satisfied faces a feasibility dilemma, and I shall characterize certain conceptions of rationality that differ according to whether or not they admit such a possibility. A second issue concerns the number of options that may be deemed rational in a decision problem. Is rationality sufficiently determinate that it always dictates precisely one choice, or may there be more than one rationally permissible option? Is there anything about rationality itself that guarantees that any of the possible options could rationally be chosen? I shall call this issue – whether the concept of rationality itself places any limits on the number of options that may be deemed rational in a given problem – the numbers problem. (shrink)

We apply an online optimization process based on machine learning to the production of Bose-Einstein condensates. BEC is typically created with an exponential evaporation ramp that is optimal for ergodic dynamics with two-body s-wave interactions and no other loss rates, but likely sub-optimal for real experiments. Through repeated machine-controlled scientific experimentation and observations our ’learner’ discovers an optimal evaporation ramp for BEC production. In contrast to previous work, our learner uses a Gaussian process to develop a statistical model of the (...) relationship between the parameters it controls and the quality of the BEC produced. We demonstrate that the Gaussian process machine learner is able to discover a ramp that produces high quality BECs in 10 times fewer iterations than a previously used online optimization technique. Furthermore, we show the internal model developed can be used to determine which parameters are essential in BEC creation and which are unimportant, providing insight into the optimization process of the system.

This study reports on the development of scale items derived from the pluralistic moral philosophy literature. In addition, the manner in which individuals combine aspects of the different philosophies in making ethical evaluations was explored.

We propose a technical reformulation of the measurement problem of quantum mechanics, which is based on the postulate that the final state of a measurement is classical; this accords with experimental practice as well as with Bohr’s views. Unlike the usual formulation (in which the post-measurement state is a unit vector in Hilbert space), our version actually opens the possibility of admitting a purely technical solution within the confines of conventional quantum theory (as opposed to solutions that either modify this (...) theory, or introduce unusual and controversial interpretative rules and/or ontologies).To that effect, we recall a remarkable phenomenon in the theory of Schrödinger operators (discovered in 1981 by Jona-Lasinio, Martinelli, and Scoppola), according to which the ground state of a symmetric double-well Hamiltonian (which is paradigmatically of Schrödinger’s Cat type) becomes exponentially sensitive to tiny perturbations of the potential as ħ→0. We show that this instability emerges also from the textbook wkb approximation, extend it to time-dependent perturbations, and study the dynamical transition from the ground state of the double well to the perturbed ground state (in which the cat is typically either dead or alive, depending on the details of the perturbation).Numerical simulations show that adiabatically arising perturbations may (quite literally) cause the collapse of the wave-function in the classical limit. Thus, at least in the context of a simple mathematical model, we combine the technical and conceptual virtues of decoherence (which fails to solve the measurement problem but launches the key idea that perturbations may come from the environment) with those of dynamical collapse models à la grw (which do solve the measurement problem but are ad hoc), without sharing their drawbacks: single measurement outcomes are obtained (instead of merely diagonal reduced density matrices), and no modification of quantum mechanics is needed.

This article uses Arndt's depiction of marketing epistemology to suggest a possible explanation for the lack of emphasis on marketing ethics within the marketing literature. While a growing number of writers are turning their attention to the area, marketing's heavy reliance on logical empiricism has contributed to a disinclination in the development of this area. Only through recent and numerous revelations of misconduct has the discipline of marketing responded to its ethical dimensions.

This study represents an improvement in the ethics scales inventory published in a 1988 Journal of Business Ethics article. The article presents the distillation and validation process whereby the original 33 item inventory was reduced to eight items. These eight items comprise the following ethical dimensions: a moral equity dimension, a relativism dimension, and a contractualism dimension. The multidimensional ethics scale demonstrates significant predictive ability.

This article focuses on the issue of finding and illustrating a common ground for discussions between those academics involved in the science of entrepreneurial behavior and those involved in the ethics of entrepreneurial behavior. Several articles appeared in the April 1994 Business Ethics Quarterly on the relationship between the science of business and business ethics. In one article by Weaver and Trevino (1994; 130–143), the authors proposed three possible relationships between the normative and empirical business ethics. The author of another (...) article in that issue, Tom Donaldson (1994; 157–169), endorsed only one of the three relationships (165) offered by Weaver and Trevino and argued against the others. The relationship endorsed by Donaldson was called “symbiosis.” In doing so he recognized that both normative and empirical insights are necessary to business ethics. This article follows the combinedreasoning of these authors by describing a symbiotic relationship between the empirical and normative requirements of trust building for entrepreneurs. (shrink)

A framework is designed to aid the marketing decision maker in choosing between deontological and utilitarian reasoning when attempting to solve ethical problems. the framework uses miller's theory of living systems to develop a hierarchy of exchanges as a basis for analysis. then the historical appeal of deontology and utilitarianism are analyzed with respect to the hierarchy.

Research using mHealth apps has the potential to positively impact health care management and outcomes. However, choosing an appropriate mHealth app may be challenging for the health researcher. The author team used existing evaluation tools, checklists, and guidelines to assess selected mHealth apps to identify strengths, challenges, and potential gaps within existing evaluation tools. They identified specific evaluation tool components, questions, and items most effective in examining app content, usability, and features, including literacy demand and cultural appropriateness; technical information; practical (...) aspects of app functionality; and evolving capabilities of mobile medical apps. Challenges included the subjective nature of the results, time required to complete the evaluation, lack of emphasis on evidence‐based content, and inadequate tool flexibility. Health researchers considering the integration of mobile apps into research will benefit from evaluation tools that assess both evidence‐based content and the ability of the mobile app to securely integrate with other digital technologies involved in patient care. Next steps will include the involvement of health care providers and professionals, including nurses a wide range of expertise, to develop an mHealth evaluation tool that focuses on identifying quality, evidence‐based mobile apps into patient outcomes research.

The quest for molecular mechanisms that guide axons or specify synaptic contacts has largely focused on molecules that intuitively relate to the idea of an “instruction.” By contrast, “permissive” factors are traditionally considered background machinery without contribution to the information content of a molecularly executed instruction. In this essay, I recast this dichotomy as a continuum from permissive to instructive actions of single factors that provide relative contributions to a necessarily collaborative effort. Individual molecules or other factors do not constitute (...) absolute instructions by themselves; they provide necessary context for each other, thereby creating a composite that defines the overall instruction. The idea of composite instructions leads to two main conclusions: first, a composite of many seemingly permissive factors can define a specific instruction even in the absence of a single dominant contributor; second, individual factors are not necessarily related intuitively to the overall instruction or phenotypic outcome.

This article discusses the major criticisms posed in On Measuring Ethical Judgments concerning our ethics scale development work. We agree that the authors of the criticism do engage in what they accurately refer to as armchair theorizing. We point out the errors in their comments.

Source preference in which equally distributed risks may be valued differently has been receiving increasing attention. Using subjects recruited in Berkeley, Fox and Tversky demonstrate a familiarity bias in source preference—betting on a less than even-chance event based on San Francisco temperature is valued more than betting on a better than even-chance event based on Istanbul temperature. Neophobia is associated with the amygdala which is GABA-rich and is known to be modulated by benzodiazepines as anxiolytic agents that enhance the activity (...) of the GABAA receptor in processing anxiety and fear. This leads to our hypothesis that familiarity bias in decision making may be explained by polymorphic variations in this receptor mediated by anxiety regulation in the amygdala. In two companion studies involving Beijing-based subjects, we examine 10 single nucleotide polymorphisms of GABRB2 and find 7 SNPs each showing negative association between familiarity bias—preference for betting on parity of Beijing temperature over Tokyo temperature—and having at least one minor allele. In an imaging genetics study of a subsample of subjects based on the SNP with the most balanced allelic distribution, we find that subjects’ familiarity bias in terms of risk aversion towards bets on the parity of the temperature of 20 Chinese cities is negatively associated with their post-scanning familiarity ratings of the cities only for those with no minor allele in this SNP. Moreover, familiarity bias is positively associated with activation in the right amygdala along with the brain’s attention networks. Overall, our findings help discriminate between ambiguity aversion and familiarity bias in source preference and supports our gene–brain–behavior hypothesis of GABAergic modulation of amygdala activation in response to familiarity towards the source of uncertainty.

The conceptual model presented in this article argues that corporations exhibit specific behaviors that signal their true level of moral development. Accordingly, the authors identify five levels of moral development and discuss the dynamics that move corporations from one level to another. Examples of corporate behavior which are indicative of specific stages of moral development are offered.

This comment is offered in response to Hansen's "A Multidimensional Scale for Measuring Business Ethics: A Purification and Refinement". Five issues arising from Hansen's purification and refinement efforts are addressed. These include the issues of parsimony, predictive validity, collinearity, reliability, and what we see as a confusion between normative and positive theory.

This research examines, in a general manner, the degree and character of perceptual congruity between salespeople and managers on ethical issues. Salespeople and managers from a diversity of organizations were presented with three scenarios having varying degrees of ethical content and were asked to evaluate the action of the individual in each scenario. Findings indicate that, in every instance, the participating managers tended (1) to be more critical of the action displayed in the scenarios, (2) to view the action as (...) violating a sense of contract or promise, and (3) to view the action as less culturally acceptable than did the salespeople.

Replicating or exceeding human intelligence, not just in particular domains but in general, has always been a major goal of Artificial Intelligence (AI). We argue here that “human intelligence” is not only ill-defined, but often conflated with broader aspects of human psychology. Standard arguments for replicating it are morally unacceptable. We then suggest a reframing: that the proper goal of AI is not to replicate humans, but to complement them by creating diverse intelligences capable of collaborating with humans. This goal (...) renders issues of theory of mind, empathy, and caring, or community engagement, central to AI. It also challenges AI to better understand the circumstances in which human intelligence, including human moral intelligence, fails. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:SHE WHO IS: WHO IS SHE? * ROBIN DARLING y OUNG The Catholic University of America Washington, D.C. WHEN ON AN ordinary Sunday morning in any Catholic church, women sign themselves with the cross, eciting the Trinitarian names of Father, Son, and Holy Spirit as they do it, are they unwittingly, or perversely, conspiring in their own oppression and suffering? What of their prayers to God the Father, (...) or to Jesus their Lord and brother, or their communion with him in the sacrament of the Eucharist? Or what of their salutation and veneration of Mary, called the Blessed Mother? She Who Is begs these particular questions because its author has neglected to consider the import of the Christian sacramental life as she forms a theology which primarily aims to benefit women. But the ·entire direction of the work makes it hard to conclude anything but that the answer to the above would be "yes." Women who profess and practice a Catholicism unreformed by feminist theory must by implication be deluded (at best) or malicious (at worst) because they have failed to realize the connection, personal and communal, between a " classical theism " which has produced masculinized language for God supported by a consonantly oppressive institution, and the worldwide political and economic domination which has yielded massive human suffering, most notably among women. Extend the logic, and it is not too much to say that the hypothetical women of the first paragraph might as well consume without objection every papal pro- *This essay is a review of Elizabeth A.

Of course, this connection is only hinted at in the book; references to political realia are allusions only, such as in the following evocation of a feminine God's revolutionary power: [The theological symbol of] She Who Is challenges every structure and attitude that assigns superiority to ruling men on the basis of their supposed greater godlikeness. If the mystery of God is no longer spoken about exclusively or even primarily in terms of the dominating male, a forceful linchpin holding up structures of patriarchal rule is removed (p. 243). The book's actual purpose is to promote a revisionist theological (or thealogical) language in order to repair the damage purportedly done to women by centuries of the other. If the pretended area of discussion is the language we employ to designate the mystery of the Godhead, the actual theater of operations is the language used in the church to communicate the faith and to evangelize. Johnson's book wishes to promote, not primarily theological reflection, but a program of revision in which-based on the premise that since God is unknowable, one set of terms is as good as another-" masculine " language for God will give way to feminized language, in which the deity appears in the image of the female human being. As opposed to the projected imago viri who presides over creation as a remote and unresponsive God, the mother God of Johnson's proposal is essentially a manifestation of the eternal feminine : in a panentheistic theology, She Who Is both plays and suffers with her wounded creatures. When She is recognized, Johnson asserts, " theology will have come of age." Not only that, but justice is more likely to be accomplished on earth. But will the faith of those women, not all of whom are subservient, who live and thrive within the Catholic tradition, have been counted? This is unlikely, because those who have not experienced the feminist "awakening" are in the view of this book primarily missionary objects who remain to be converted. Women who are unaware of their oppression by " classi- SHE WHO IS 325 cal theism " are presumably afflicted by the " false consciousness " with which leftists of this century have characterized those potentially liberated souls who have not yet realized their enslavement. As Johnson herself says, those who disagree exhibit the symptoms of blindness, or "scotosis... (shrink)

When subordinates have suffered an unfairness, managers sometimes try to compensate them by allocating something extra that belongs to the organization. These reactions, which we label asmanagerial Robin Hood behaviors, are undertaken without the consent of senior leadership. In four studies, we present and test a theory of managerial Robin Hoodism. In study 1, we found that managers themselves reported engaging in Robin Hoodism for various reasons, including a moral concern with restoring justice. Study 2 results suggested (...) that managerial Robin Hoodism is more likely to occur when the justice violations involve distributive and interpersonal justice rather than procedural justice violations. In studies 3 and 4, when moral identity (trait or primed) was low, both distributive and interpersonal justice violations showed similar relationships to managerial Robin Hoodism. However, when moral identity was high, interpersonal justice violations showed a strong relationship to managerial Robin Hoodism regardless of the level of distributive justice. (shrink)

The idea that the concept ‘knowledge’ has a distinctive function or social role is increasingly influential within contemporary epistemology. Perhaps the best-known account of the function of ‘knowledge’ is that developed in Edward Craig’s Knowledge and the state of nature (1990, OUP), on which (roughly) ‘knowledge’ has the function of identifying good informants. Craig’s account of the function of ‘knowledge’ has been appealed to in support of a variety of views, and in this paper I’m concerned with the claim that (...) it supports a sort of epistemic contextualism, which is (roughly) the view that the semantic contents and truth-conditions of ‘knowledge’ ascriptions - instances of ‘S knows that p’- depend on and vary with the context of ascription (see, for instance, John Greco’s ‘What’s wrong with contextualism’, Philosophical Quarterly [2008]). Prima facie, this claim should strike us as surprising. A number of concepts and linguistic items (words, sentences) serve functions that have little or nothing to do with semantics. However, I argue that, on the best interpretation of talk of the function of a concept such as ‘knowledge’, the function of ‘knowledge’ is relevant to semantics. Along the way I also suggest how to improve on what I call the ‘usual argument’ that Craig’s account of the function of ‘knowledge’ supports epistemic contextualism. (shrink)

Role morality can be defined as “claim(ing) a moral permission to harm others in ways that, if not for the role, would be wrong” (A. Applbaum: 1999, Ethics for Adversaries: The Morality of Roles in Public and Professional Life (Princeton University Press, Princeton, NJ) p. 3). Adversarial situations resulting in role morality occur most frequently in the fields of law, business, and government. Within the realm of accounting, professional obligations may place the accountant in a situation where he/she is susceptible (...) to the pressures of role morality. If the accountant engages in acts consistent with role morality, significant harm to others may result. The current study represents an initial investigation into role morality in accounting and includes survey data from three samples of professionals: accountants, physicians, and attorneys. Results suggest that accountants generally do not agree that role morality is acceptable. Additionally, when compared to the groups of physicians and attorneys, physicians agree the least with role morality, while attorneys agree the most. Implications for practicing accountants and suggestions for future research into the theory of role morality are offered. (shrink)

This book surveys and examines the most famous philosophical arguments against building a machine with human-level intelligence. From claims and counter-claims about the ability to implement consciousness, rationality, and meaning, to arguments about cognitive architecture, the book presents a vivid history of the clash between the philosophy and AI.
