This paper uses the intuition from the game of chickento model client-auditor financial reporting and audit effort strategies. Within an ethical context, our model is concerned with the client misreporting and its detection by the auditor. The paper uses a welfare game(similar to the game of chicken) to more formally model client-auditor strategies. The welfare game is then extended to provide additional insight into ethical and audit effort issues.Such a welfare gameprovides equilibrium in mixed strategies. This mixed strategy solution makes (...) possible four outcomes from the game: 1) Financial Statements are fairly presented by client and the auditor performs a normal audit, 2) Financial Statements are fairly presented by client and the auditor performs an extended audit (over auditing), 3) Financial State-ments are misstated by client and detected by the auditor, and 4) Financial Statements are misstated by client and not detected by the auditor (audit failure despite no intended unethical action on the part of the auditor).

Should engineering ethics be taught? Despite the obvious truism that we all want our students to be moral engineers who practice virtuous professional behavior, I argue, in this article that the question itself obscures several ambiguities that prompt preliminary resolution. Upon clarification of these ambiguities, and an attempt to delineate key issues that make the question a philosophically interesting one, I conclude that engineering ethics not only should not, but cannot, be taught if we understand “teaching engineering ethics” to mean (...) training engineers to be moral individuals (as some advocates seem to have proposed). However, I also conclude that there is a justification to teaching engineering ethics, insofar as we are able to clearly identify the most desirable and efficacious pedagogical approach to the subject area, which I propose to be a case study-based format that utilizes the principle of human cognitive pattern recognition.

Despite its importance, the linkage between genetic and cultural evolution has until now been little explored. An understanding of this linkage is needed to extend evolutionary theory so that it can deal for the first time with the phenomena of mind and human social history. We characterize the process of gene-culture coevolution, in which culture is shaped by biological imperatives while biological traits are simultaneously altered by genetic evolution in response to cultural history. A case is made from both theory (...) and evidence that genetic and cultural evolution are inseverable, and that the human mind has tended to evolve so as to bias individuals toward certain patterns of cognition and choice rather than others. With the aid of mathematical models we trace the coevolutionary circuit: The genes prescribe structure in developmental pathways that lay down endocrine and neural systems, imposing regularities in the development of cognition and behavior; these regularities translate upward into holistic patterns of culture, which can be predicted in the form of probability density distributions ; natural selection acts within human history to favor certain epigenetic rules over others; and the selection alters the frequencies of the underlying genes. The effects of genetic and cultural changes reverberate throughout the circuit and are consequently tested with the passage of each life cycle. In addition to modeling gene-culture coevolution, we apply methods from island biogeography and information theory to examine the cultural capacity of the genes, the factors determining the magnitude of cultural diversity, and the possible reasons for the uniqueness of the human achievement.

The Belmont Report’s distinction between research and the practice of accepted therapy has led various authors to suggest that these purportedly distinct activities should be governed by different ethical principles. We consider some of the ethical consequences of attempts to separate the two and conclude that separation fails along ontological, ethical, and epistemological dimensions. Clinical practice and clinical research, as with yin and yang, can be thought of as complementary forces interacting to form a dynamic system in which the whole (...) exceeds the sum of its parts. Just as effective clinical practice cannot exist without clinical research, meaningful clinical research requires the context of clinical practice. We defend this thesis by triangulation, that is, by outlining how multiple investigators have reached this conclusion on the basis of varied theoretical and applied approaches. More confidence can be placed in a result if different methods/viewpoints have led to that result. (shrink)

In this essay, we defend the design of the Salk polio vaccine trial and try to put some limits on the role schemata should play in designing clinical research studies. Our presentation is structured as a response to de Freitas and Pietrobon who identified the CONSORT statement as a schema that would have, had it existed at the time, ruled out the design of the Salk polio vaccine trial of 1954 in favor of a completely randomized controlled clinical trial. We (...) argue that large-scale public health interventions often require evidence beyond simple efficacy, the limit of what an RCT can provide, and that the design actually adopted for the Salk trial represented a reasonable—albeit imperfect—compromise. This is of more than historical interest in that many contemporary studies are of the scale and scope to require a more pragmatic, rather than explanatory, approach to study design. (shrink)

The purpose of this paper is to review the rising influence of commercialism in American medicine and to examine some of the consequences of this trend. Increased competition subverts physician collegiality, draws hospitals into for-profit ownership and behavior, and leads clinical investigators into secrecy and possibly into bias and abuse. Medicine faces a deprofessionalization evidenced in loss of control over the clinical setting and over self-regulation. Health care becomes a commodity relying on cultivation of desires instead of satisfaction of needs, (...) even as many basic needs go unmet. Patients become consumers empowered with lawsuits and the connection of medicine to the relief of suffering is attenuated. Medical encounters are increasingly impersonal, dominated by specialization, technology, and bureaucracy. Patients are losing their physician-advocates to new conflicts of interests, physicians are losing their impulse to charity, and trust in the doctor-patient relationship and in medicine generally is eroding.

Memory exhibits episodic superposition, an analog of the quantum superposition of physical states: Before a cue for a presented or unpresented item is administered on a memory test, the item has the simultaneous potential to occupy all members of a mutually exclusive set of episodic states, though it occupies only one of those states after the cue is administered. This phenomenon can be modeled with a nonadditive probability model called overdistribution (OD), which implements fuzzy-trace theory's distinction between verbatim and gist (...) representations. We show that it can also be modeled based on quantum probability theory. A quantum episodic memory (QEM) model is developed, which is derived from quantum probability theory but also implements the process conceptions of global matching memory models. OD and QEM have different strengths, and the current challenge is to identify contrasting empirical predictions that can be used to pit them against each other. (shrink)

That dichotomization is, at least under certain circumstances, a bad idea is not news. A well-known, early example is the biblical story of King Solomon, who used the absurdity of the procedure to help adjudicate a dispute between two women who each claimed to be the mother of a contested child. Solomon reasoned that his proposal to split the child into two, giving half to each woman, would be abhorrent to the real mother, and when one of the women objected (...) while the other thought the proposal was "only fair," the choice between the women was made obvious.Things, however, are not always so clear-cut, and it is not difficult to find arguments that point to the advantages that accrue to those that simplify matters....

Louis Frédéric Ancillon was a member of the Prussian Academy of Sciences and Belles Lettres whose imagined dialogue between Berkeley and Hume was read to the Academy in 1796 and published in 1799. It is important as an indicator of the reception of Hume and Berkeley in francophone philosophical circles in late eighteenth-century Prussia. Our introduction is followed by an English translation with notes.

Friendship, in its nature, purpose, and effects, has been an important concern of philosophy since antiquity. It was of particular significance in the life of Gilles Deleuze, one of the most original and influential philosophers of the late twentieth century. Taking L'Abécédaire de Gilles Deleuze -- an eight-hour video interview that was intended to be aired only after Deleuze's death -- as a key source, Charles J. Stivale examines the role of friendship as it appears in Deleuze's work and (...) life. Stivale develops a zigzag methodology practiced by Deleuze himself to explore several concepts as they relate to friendship and to discern how friendship shifts, slips, and creates movement between Deleuze and specific friends. The first section of this study discusses the elements of creativity, pedagogy, and literature that appear implicitly and explicitly in his work. The second section focuses on Deleuze's friendships with Foucault, Derrida, Claire Parnet, and Félix Guattari and reveals his conception of friendship as an ultimately impersonal form of intensity that goes beyond personal relationships. Stivale's analysis offers an intimate view into the thought of one of the greatest thinkers of our time. (shrink)

Identifying what the differences are or ought to be between Catholic health care organizations and their non-Catholic counterparts is the subject of great debate. The author responds to the essays in this volume by Dennis Brodeur, Clarke E. Cochran and Christopher J. Kauffman, each of which represents a different perspective in the discussion of what is unique about Catholic health care.

The H‐NS protein is a major component of the nucleoid in Gram‐negative bacterial cells. It is a global regulator of transcription that affects the expression of many genes, including virulence genes in pathogenic species. At a local level, it facilitates the formation of nucleoprotein structures that repress transcriptional promoter function. H‐NS can form bridges between different DNA molecules or between different sections of the same molecule, allowing it to compact and impose structure on the nucleoid. A recent paper by Dame (...) et al.1 reports new insights into H‐NS‐mediated DNA bridging that were obtained using an optical tweezers device.

DRGs may contain costs, but they threaten to restrict access to health care, to compromise its quality, and to impede the development of new medical technologies. Immediate corrections are necessary to ensure that hospitals continue to serve the poorest and sickest.
