Recall that a subset X of a Boolean algebra A is independent if for any two finite disjoint subsets F , G of X we have ∏ x∈F x ∏ y∈G −y≠0. The independence of a BA A , denoted by Ind, is the supremum of cardinalities of its independent subsets. We can also consider the maximal independent subsets. The smallest size of an infinite maximal independent subset is the cardinal invariant i , well known in the case A= P (...) / fin . In this article we consider the collection of all cardinalities of infinite maximal independent subsets of a BA A ; we call this set the spectrum of infinite maximal independent subsets , denoted by Spind. Note that infinite maximal independent subsets exist in any BA which is not superatomic. The main result is that any set of infinite cardinals can occur as Spind for some infinite BA A . Beyond this we give results concerning the way that Spind changes under various algebraic operations. However, the basic components of most algebras that we deal with are free algebras. (shrink)

Donald F. Koch supplies the only extant complete transcription of the annual three-course sequence on ethics Dewey gave at the University of Chicago from 1894 to 1904. Koch argues that these lectures offer the best systematic, overall introduction to Dewey’s approach to moral philosophy and are the only account showing the unity of his views in nearly all phases of ethical inquiry. These lectures are the only work by Dewey to set forth a complete theory of moral language. They (...) offer a clear illustration of the central methodological questions in the development of a pragmatic instrumentalist ethic and the actual working out of the instrumentalist approach as distinct from simply presenting it as a conclusion.

The shape, function, and dynamic of the field of bioethics is in constant flux, and nowhere is this more apparent than at gatherings of those immersed in th discipline. This section presents coverage and commentary on conferences and settings where voices out-side the mainstream of biomedical ethics can be heard.

Recognizing the growing interdependence of the European Union and the importance of codes of conduct in companies’ operations, this research examines the effect of a country’s culture on the implementation of a code of conduct in a European context. We examine whether the perceptions of an activity’s ethicality relates to elements found in company codes of conduct vary by country or according to Hofstede’s (1980, Culture’s Consequences (Sage Publications, Beverly Hills, CA)) cultural constructs of: Uncertainty Avoidance, Masculinity/Femininity, Individualism, and Power (...) Distance. The 294 individuals, who participated in our study, were from 8 Western European countries. Their responses to our 13 scenarios indicate that differences in the perceptions of ethicality associate primarily with the participants’ country as opposed to their employer (i.e., accounting firm), employment level, or gender. The evidence also indicates that these country differences associate with Hofstede constructs of Individualism and Masculinity. (shrink)

This study explored how disclosure of financial conflicts of interest influences naïve or “lay” individuals’ perceptions of the ethicality of researcher conduct. On a between-subjects basis, participants read ten scenarios in which researchers disclosed or failed to disclose relevant financial conflicts of interest. Participants evaluated the extent to which each vignette represented a FCOI, its possible influence on researcher objectivity, and the ethics of the financial relationship. Participants were then asked if they had completed a college-level ethics course. Results indicated (...) that FCOI disclosure significantly influenced participants’ perceptions of the ethicality of the situation, but only marginally affected perceptions of researcher objectivity and had no significant influence on perceptions of the existence of FCOIs. Participants who had previously completed a college-level ethics course appeared more sensitive to the importance of FCOI disclosure than those who lacked such background. This result suggests that formal ethical training may help individuals become more critical consumers of scientific research. (shrink)

Specifying exact selection pressures for identifying adaptations is unnecessary. Novel behaviors are not spandrels since they can only develop because of prior functions. An adaptationist approach has a high prior probability, whereas spandrel hypotheses attempt to prove a negative. The concept of maladaptive spandrel is criticized. The utility of dysfunctional states for identification of adaptations gone wrong is emphasized.

Retractions have traditionally been reserved for correcting the scientific record and discouraging research misconduct. Nonetheless, the potential for actual societal harm resulting from accurately reported published scientific findings, so-called information hazards, has been the subject of several recent article retractions. As these instances increase, the extent of support for such decisions among the scientific community and lay public remains unclear. Undergraduates (Study 1) and federally funded researchers (Study 2) reported their support for retraction decisions described as due to misconduct, honest (...) errors, or potential information hazards. Participants supported retraction on the former two grounds more than the latter. Despite limited support, women remained more receptive to retractions based on information hazards. Activist tendencies additionally predicted undergraduate men’s receptivity. Receptivity toward retraction due to information hazards was unrelated to scientists’ engagement in activism, suggesting that formal scientific training affords researchers an ability to separate personal and professional values in scientific discourse. Findings could inform the development of educational materials that may aid less experienced scientists and the lay public in understanding retraction ethics. (shrink)

What follows raises objections to some arguments that claimthat a principle of applicability of ordinary pain talkconstrains developments in the pain sciences. A more apt pictureof lay use of pain language shows its non-theoretic character.Since instrumentalism and eliminativism are philosophical viewsabout the status of theories of pain, neither is a threatto clinical use of standard pain lingo. Perfected pain theoryis likely to enhance and improve pain language in clinicalsettings, should such theory find its way into popular ideasand talk of pain.

Engaging Eriugena, Eckhart and Cusanus contains two new essays and nine others published between 2005 and 2019. The essays explore Eriugena, Eckhart and Cusanus as bold thinkers deeply engaged with their times and culture. John Scottus Eriugena, Meister Eckhart and Nicholas of Cusa are key figures in the medieval Christian Neoplatonic tradition. This book focuses on their engagement with practical, experiential issues and controversies. Eriugena revises Genesis' Adam and Eve narrative and makes sexual difference and overcoming it central to his (...) Periphyseon. Eckhart's Annunciation sermons urge his hearers to give birth to God's son within their lives, and he develops a distinctive approach to pain and suffering. His radical preaching on the Eucharist and mystical union was judged heretical, but was later taken up by Nicholas of Cusa. Coins and banking became key symbols in Cusanus' exploration of humanity as created in God's image, and he used mechanical clocks in reflecting on time and eternity. 'Engagement' also describes these thinkers' reception of their predecessors and how later readers appropriated their works. Eriugena struggled with the legacy of Augustine and the Greek Fathers. Eckhart's theology of suffering provoked varied responses from his students Henry Suso and Johannes Tauler, and the twentieth-century therapist Ursula Fleming. Cusanus provides the volume's lynchpin as two articles analyse his reading of Eriugena and Eckhart, and a third discusses how he deftly countered Johannes Wenck's accusations of heresy. The book will be of interest to students of Medieval Philosophy, Theology, Spirituality and their place within Cultural History. (shrink)

The scientific method is a potentiation of common sense, exercised with a specially firm determination not to persist in error if any exertion of hand or mind can deliver us from it. We are all affected by our past. I grew up in the “Land of Lincoln,” so stories about the 16th U.S. President, “Honest Abe” as we called him, were unavoidable in my youth. In particular, we learned that Abraham Lincoln never told a lie. Well, one day when I (...) was 10, a friend caused a bike accident that broke my left clavicle. When my parents asked me what had happened, I lied. I told them that I fell against the corner of a building. As I recall, I lied in order to protect my friend. His family was very poor, and my young mind .. (shrink)
