The acid rain issue came into prominence because scientists kept telling the world of acid rain's potential devastating effects. Yet, the acid rain debate was marked by mistrust between American and Canadian scientists. The signing of the Air Quality Accord in 1991 appears to have quelled this divisiveness and promises to bring about a new era of scientific cooperation. Using surveys of acid rain scientists in the United States and Canada across three time periods, this study finds both similarities and (...) differences between how Canadian and American scientists view many of the issues surrounding the acid rain debate.

This paper explores the concept of “livity,” the ground of Rastafari subjectivity. In its multifaceted nuances, “livity” represents the Rastafari invention of a religious tradition and discourse, whose ethos was fundamentally sacred, signified the immanence of the Absolute in dialectic with the Rastafari worldview and life world. Innovatively, the Rastafari coined the term “livity” to a discourse to combat despair, damnation, social death, and the existential chaos-monde they referred to as Babylon. In the process, the Rastafari reclaimed their power to (...) name their world. The Rastafari neologism “livity” articulated a mysticism, alternative spatial visions, and a positive technology of the self that revalorized blackness, explored, and interrogated profound dimensions of the human condition, from within the Jamaican context, that inevitably brought them into conflict with the local colonial authorities and implicitly shifted the model of social relations between the master and slave.

Books of extracts are often written to celebrate a reputation, or to move the reader to greater exertions by the words of the great. Neither of these reasons account for the assembling of this selection. For the traditional book of extracts reflects a traditional conception of their role, and below this conception is rejected. Rather, these extracts are thought of as working documents, selected to provide an occasion for critical and reflective thought, and presented in an order designed to ease (...) the strain we always feel when we think warily, acutely, and yet receptively. This book then deals with that contribution to discussion made by four past educationists. It is interesting to note how long their writing has formed part of the subject-matter of courses, without any precise ideas as to where they fit in the scheme of things. The layout of this introduction and the ordering of the following extracts is intended to try and help meet present needs. (shrink)

The case and commentaries below were developed as part of a project, Graduate Research Ethics Education, undertaken by the Association for Practical and Professional Ethics with funding from the National Science Foundation (NSF Grant No. SBR 9421897 and NSF Grant No. 9817880). The project aims at training graduate students in research ethics and building a community of scientists and engineers who are interested in and capable of teaching research ethics. As part of the project, each graduate student participant develops a (...) case for use in teaching and writes a commentary to go with the case, and then a staff member is asked to write additional commentary on the case. The case below was written in the second year of the project and was published in Research Ethics: Cases and Commentaries edited by B. Schrag, Association for Practical and Professional Ethics, Bloomington, Indiana, Vol. II (1998). Publication of these cases and commentaries will be a recurring feature of Science and Engineering Ethics. (shrink)

BackgroundIn the Canadian Alliance for Healthy Hearts and Minds (CAHHM) cohort, participants underwent magnetic resonance imaging (MRI) of the brain, heart, and abdomen, that generated incidental findings (IFs). The approach to managing these unexpected results remain a complex issue. Our objectives were to describe the CAHHM policy for the management of IFs, to understand the impact of disclosing IFs to healthy research participants, and to reflect on the ethical obligations of researchers in future MRI studies.MethodsBetween 2013 and 2019, 8252 participants (...) (mean age 58 ± 9 years, 54% women) were recruited with a follow-up questionnaire administered to 909 participants (40% response rate) at 1-year. The CAHHM policy followed a restricted approach, whereby routine feedback on IFs was not provided. Only IFs of severe structural abnormalities were reported.ResultsSevere structural abnormalities occurred in 8.3% (95% confidence interval 7.7–8.9%) of participants, with the highest proportions found in the brain (4.2%) and abdomen (3.1%). The majority of participants (97%) informed of an IF reported no change in quality of life, with 3% of participants reporting that the knowledge of an IF negatively impacted their quality of life. Furthermore, 50% reported increased stress in learning about an IF, and in 95%, the discovery of an IF did not adversely impact his/her life insurance policy. Most participants (90%) would enrol in the study again and perceived the MRI scan to be beneficial, regardless of whether they were informed of IFs. While the implications of a restricted approach to IF management was perceived to be mostly positive, a degree of diagnostic misconception was present amongst participants, indicating the importance of a more thorough consent process to support participant autonomy.ConclusionThe management of IFs from research MRI scans remain a challenging issue, as participants may experience stress and a reduced quality of life when IFs are disclosed. The restricted approach to IF management in CAHHM demonstrated a fair fulfillment of the overarching ethical principles of respect for autonomy, concern for wellbeing, and justice. The approach outlined in the CAHHM policy may serve as a framework for future research studies.Clinical trial registrationhttps://clinicaltrials.gov/ct2/show/nct02220582. (shrink)

The emergence and development of the field of clinical ethics coincided with the revitalization of moral philosophy following the publication of John Rawls’ ma...

Number concepts must support arithmetic inference. Using this principle, it can be argued that the integer concept of exactly ONE is a necessary part of the psychological foundations of number, as is the notion of the exact equality - that is, perfect substitutability. The inability to support reasoning involving exact equality is a shortcoming in current theories about the development of numerical reasoning. A simple innate basis for the natural number concepts can be proposed that embodies the arithmetic principle, supports (...) exact equality and also enables computational compatibility with real- or rational-valued mental magnitudes.

The shapes of neurons and glial cells dictate many important aspects of their functions. In olfactory systems, certain architectural features are characteristics of these two cell types across a wide variety of species. The accumulated evidence suggests that these common features may play fundamental roles in olfactoryinformation processing. For instance, the primary olfactory neuropil in most vertebrate and invertebrate olfactory systems is organized into discrete modules called glomeruli. Inside each glomerulus, sensory axons and CNS neurons branch and synapse in patterns (...) that are repeated across species. In many species, moreover, the glomeruli are enveloped by a thin and ordered layer of glial processes. Theglomerular arrangement reflects the processing of odor information in modules that encode the discrete molecular attributes of odorant stimuli being processed. Recent studies of the mechanisms that guide the development of olfactory neurons and glial cells have revealed complex reciprocal interactions between these two cell types, which may be necessary for the establishment of modular compartments. Collectively, the findings reviewed here suggest that specialized cellular architecture plays key functional roles in the detection, analysis, and discrimination of odors at early steps in olfactory processing.

We present this special issue on positive organizational ethics (POE) to highlight those pursuing positive subjective experiences, positive attributes of individuals and groups, and positive practices that contribute to ethical and virtuous behavior in organizations. Although prior research has offered some insight in this area, there is still much to be learned about how to cultivate and sustain ethical strength in different types of organizations and how goodness can emerge from and in spite of human failings. After describing the positive (...) movement, we position POE as a discrete area of inquiry within the broader positive behavioral sciences, at the intersection of positive behavioral studies and business ethics. After defining our terms and purpose for creating the POE domain, we introduce the articles in this special issue. The introduction concludes with suggested topics for future research. (shrink)

This collection, the first of its kind, brings together specially commissioned academic essays to mark fifty years since the death of John Kennedy Toole.

When the Covid‐19 pandemic reached the United States in spring 2020, many states and hospitals announced crisis standards of care plans that used age as a categorical exclusion criterion. Such age choosing was quickly flagged as discriminatory, and so some states and hospitals shifted to embedding age as a tiebreaker deeper in their plans. Different rationales were given for using age as a tiebreaker: that younger patients were more likely to survive than older patients, that saving younger patients would save (...) more life years, and that younger patients deserved a chance to live through life's stages. We provide a critical analysis of these three rationales, noting the differences between them, and then questioning the ethical and legal justifications for such age choosing. (shrink)
