A subspace V of an infinite dimensional fully effective vector space V ∞ is called decidable if V is r.e. and there exists an r.e. W such that $V \oplus W = V_\infty$ . These subspaces of V ∞ are natural analogues of recursive subsets of ω. The set of r.e. subspaces forms a lattice L(V ∞ ) and the set of decidable subspaces forms a lower semilattice S(V ∞ ). We analyse S(V ∞ ) and its relationship with L(V (...) ∞ ). We show: Proposition. Let U, V, W ∈ L(V ∞ ) where U is infinite dimensional and $U \oplus V = W$ . Then there exists a decidable subspace D such that U |oplus D = W. Corollary. Any r.e. subspace can be expressed as the direct sum of two decidable subspaces. These results allow us to show: Proposition. The first order theory of the lower semilattice of decidable subspaces, Th(S(V ∞ )), is undecidable. This contrasts sharply with the result for recursive sets. Finally we examine various generalizations of our results. In particular we analyse S * (V ∞ ), that is, S(V ∞ ) modulo finite dimensional subspaces. We show S * (V ∞ ) is not a lattice. (shrink)

When physicians today appeal to “conscience,” it has been alleged such exercises pejoratively reflect “conscience without consequence” as contemporary practitioners are said to be insulated from the consequences of such decisions. It has also been implied these physicians avoid traditional professional responsibilities—including providing charity care and making house or night calls. The assertions demand clarification. Fundamentally, what traits constitute an integrated professionalism specific to Christian physicians? Historical evidence verifies sanctity-of-life affirmations by Christian physicians throughout Church history. However, surveying Christian medical (...) practices in the initial centuries of the Common Era, and more recently in the United States, supports integration of conscience with philanthropy and a rigorous definition of a medical vocation. These suggest there may be deterioration in a holistic commitment to medicine in the United States. Reclaiming an integrated professional paradigm—wherein conscience, philanthropia, and vocation are combined—is essential to an authentic contemporary witness. (shrink)

Del Giudice provides an extension of the life history theory of attachment that incorporates emerging data suggestive of sex differences in avoidant male and preoccupied female attachment patterns emerging in middle childhood. This commentary considers the place of disorganized attachment within this theory and why male children may be more prone to disorganized attachment by drawing on Trivers's parental investment theory.

Although research findings have always been subject to abuse, scientific advances and recent events have increased concern about the perils of some biomedical knowledge. The Council on Ethical and Judicial Affairs addresses this potential in its guidelines for physician–researchers. The guidelines do not advance many novel ideas or provide substantive guidance for PRs. Advocacy for professionalism, weighing costs and benefits, and balanced oversight are uncontroversial and have been proposed before. The difficult task is to define what they require, and here (...) the guidelines are vague. We discuss critically two issues that deserve careful attention. (shrink)

This is a supplemental text for all philosophy courses that facilitates, invigorates, and enhances student learning by teaching students to read and write effectively.

The 1980s witnessed a dramatic increase in hostile takeovers in the United States. Proponents argue that well- planned mergers enhance the value of the firm and the value of the firm to society. Critics typically argue that undesired takeovers ultimately harm society due to external costs not borne by the acquiring firm. To be socially responsible, the manager must consider the effects of the merger/acquisition on all stakeholders. Different traditional ethical frameworks for decision making are proposed and reviewed. A model (...) is proposed. (shrink)

This study examines the role of acculturation in shaping consumers’ views of ethics. Specifically, it examines the relationships between the desire to keep one’s original culture, the desire to adopt the host culture, and the four dimensions of the Muncy and Vitell (Journal of Business Research Ethics 24(4), 297, 1992) consumer ethics scale. Using two separate immigrant populations – one of former Middle-Eastern residents now living in the U.S. and the other of Asian immigrants in the U.S. – results indicate (...) that those who want to keep their original culture are less tolerant of unethical consumer activities, while those who are more willing to adopt the host culture are more tolerant of these same consumer activities. Furthermore, the immigrants in both studies who are more tolerant of unethical consumer activities are those who are generally somewhat younger and with less formal education. The relationship between gender and consumer ethics was not significant. (shrink)

What causes adolescents to develop consumer’ ethical beliefs? Prior research has largely focused on the negative influence of peers and negative patterns of parent–child interactions to explain risky and unethical consumer behaviors. We take a different perspective by focusing on the positive support of parents and peers in adolescent social development. An integrative model is developed that links parental and peer support with adolescents’ self-worth motives, their materialistic tendencies, and their consumer ethical beliefs. In a study of 984 adolescents, we (...) demonstrate support for a sequential mediation model in which peer and parental support is positively related to adolescents’ self-esteem and feelings of power, which are each associated with decreased materialism as a means of compensating for low self-worth. This reduced materialism is, in turn, associated with more ethical consumer beliefs. (shrink)

The use of Big Data—however the term is defined—involves a wide array of issues and stakeholders, thereby increasing numbers of complex decisions around issues including data acquisition, use, and sharing. Big Data is becoming a significant component of practice in an ever-increasing range of disciplines; however, since it is not a coherent “discipline” itself, specific codes of conduct for Big Data users and researchers do not exist. While many institutions have created, or will create, training opportunities to prepare people to (...) work in and around Big Data, insufficient time, space, and thought have been dedicated to training these people to engage with the ethical, legal, and social issues in this new domain. Since Big Data practitioners come from, and work in, diverse contexts, neither a relevant professional code of conduct nor specific formal ethics training are likely to be readily available. This normative paper describes an approach to conceptualizing ethical reasoning and integrating it into training for Big Data use and research. Our approach is based on a published framework that emphasizes ethical reasoning rather than topical knowledge. We describe the formation of professional community norms from two key disciplines that contribute to the emergent field of Big Data: computer science and statistics. Historical analogies from these professions suggest strategies for introducing trainees and orienting practitioners both to ethical reasoning and to a code of professional conduct itself. We include two semester course syllabi to strengthen our thesis that codes of conduct can be harnessed to support the development of ethical reasoning in, and a sense of professional identity among, Big Data practitioners.

Schnorr randomness is a notion of algorithmic randomness for real numbers closely related to Martin-Löf randomness. After its initial development in the 1970s the notion received considerably less attention than Martin-Löf randomness, but recently interest has increased in a range of randomness concepts. In this article, we explore the properties of Schnorr random reals, and in particular the c.e. Schnorr random reals. We show that there are c.e. reals that are Schnorr random but not Martin-Löf random, and provide a new (...) characterization of Schnorr random real numbers in terms of prefix-free machines. We prove that unlike Martin-Löf random c.e. reals, not all Schnorr random c.e. reals are Turing complete, though all are in high Turing degrees. We use the machine characterization to define a notion of "Schnorr reducibility" which allows us to calibrate the Schnorr complexity of reals. We define the class of "Schnorr trivial" reals, which are ones whose initial segment complexity is identical with the computable reals, and demonstrate that this class has non-computable members.

This article revisits and further develops Mitchell et al.’s (Acad Manag Rev 22(4):853–886, 1997 ) theory of stakeholder identification and salience. Stakeholder salience holds considerable unrealized potential for understanding how organizations may best manage multiple stakeholder relationships. While the salience framework has been cited numerous times, attempts to develop it further have been relatively limited. We begin by reviewing the key contributions of other researchers. We then identify and seek to resolve three residual weaknesses in Mitchell et al.’s ( 1997 (...) ) framework, thereby strengthening its foundations for further development. We argue, first, that urgency is not relevant for identifying stakeholders; second, that it is primarily the moral legitimacy of the stakeholder’s claim that applies to stakeholder salience; and last, that the salience of stakeholders will vary as the degrees of the attributes vary. These insights inform revised definitions of stakeholder salience and legitimacy, and necessitate a new theoretical underpinning for the role of legitimacy. Finally, we present an extensive agenda for future research with the objective of refueling research in stakeholder salience. (shrink)

Reagan mixes the genres of biographical essay, memoir, philosophical essay, and interview to provide the reader with a fascinating and highly readable account. The biographical essay narrates Ricoeur’s early life, his experience as a POW during the Second World War, professorships at the Sorbonne, Nanterre, and Chicago, and his “rediscovery” in and return to France after the publication of Time and Narrative. Reagan’s analysis betrays Ricoeur’s comment that “no one is interested in my life... [since] my life is my work... (...) my books and my articles.” Ricoeur’s captivity as a prisoner of war, the problems he encountered at Nanterre University as doyen of the Faculty of Letters during the 1960s, and the pain and love he and Simone felt for Olivier, their fourth child who committed suicide, are some of the intriguing and touching elements of the narrative. After Olivier’s tragic death in 1986, Ricoeur added “suffering” to the phrase “human action” whenever he wrote about the problem of human action and suffering. (shrink)

The contributors to The Moral of the Story, all preeminent political theorists, are unified by their concern with the instructive power of great literature. This thought-provoking combination of essays explores the polyvalent moral and political impact of classic world literatures on public ethics through the study of some of its major figures-including Shakespeare, Dante, Cervantes, Jane Austen, Henry James, Joseph Conrad, Robert Penn Warren, and Dostoevsky. Positing the uniqueness of literature's ability to promote dialogue on salient moral and intellectual virtues, (...) editor Henry T. Edmonson III has culled together a wide-ranging exploration of such fundamental concerns as the abuse of authority, the nature of good leadership, the significance of "middle class virtues" and the needs of adolescents. This collection reinvigorates the study of classic literature as an endeavor that is not only personally intellectually satisfying, but also an inimitable and unique way to enrich public discourse.

Nature contact has associations with emotional ill-being and well-being. However, the mechanisms underlying these associations are not fully understood. We hypothesised that increased adaptive and decreased maladaptive emotion regulation strategies would be a pathway linking nature contact to ill-being and well-being. Using data from a survey of 600 U.S.-based adults administered online in 2022, we conducted structural equation modelling to test our hypotheses. We found that (1) frequency of nature contact was significantly associated with lesser emotional ill-being and greater emotional (...) well-being, (2) effective emotion regulation was significantly associated with lesser emotional ill-being and greater emotional well-being, and (3) the associations of higher frequency of nature contact with these benefits were partly explained via emotion regulation. Moreover, we found a nonlinear relationship for the associations of duration of nature contact with some outcomes, with a rise in benefits up to certain amounts of time, and a levelling off after these points. These findings support and extend previous work that demonstrates that the associations of nature contact with emotional ill-being and well-being may be partly explained by changes in emotion regulation.

In the Snell-Maehler edition of Bacchylides there is a very comprehensive bibliography, listing almost 300 items concerned with Bacchylides poems. It is significant that 80 per cent of these were written in the first twenty years following Kenyon's publication of the Bacchylides papyri in 1897. Of the articles which have appeared since the First World War, many are concerned with more recent papyrus discoveries and a few are stylistic discussions. For most of the poems dealt with in the pioneering days (...) of Bacchylidean scholarship certain readings of the text and interpretations of it have become canonical. This article aims to show in just one poem, XVII, a few instances in which the accepted interpretations should be re-examined. In some cases new interpretations are offered, but in others older views have been resurrected and bolstered by further argument. (shrink)
