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)

A family of arguments for black hole evaporation relies on conservation laws, defined through symmetries represented by Killing vector fields which exist globally or asymptotically. However, these symmetries often rely on the idealizations of stationarity and asymptotic flatness, respectively. In non-stationary or non-asymptotically-flat spacetimes where realistic black holes evaporate, the requisite Killing fields typically do not exist. Can we 'de-idealize' these idealizations, and subsequently the associated arguments for black hole evaporation? Here, I critically examine the strategy of (...) using 'approximately Killing' fields to de-idealize black hole spacetimes and approximately extend conservation laws to non-idealized cases. I argue that this approach encounters significant challenges, undermining the use of these idealizations to justify the evaporation of realistic -- rather than idealized -- black holes, and raising questions about the justified use of such idealizations. -/- .

Christianity has contributed to environmental degradation. In terms of their role, the church youth are ipso facto part of such a contribution. However, an eco-theological diagnostic analysis cannot interpret the role of youth, especially black youth, through the same lenses. From a Black theological perspective, black youth’s role should be interpreted and discussed in terms of what Fanon and Biko describe as ‘self-hatred’ and the need for black consciousness. It is such self-hatred that gives rise to (...) environmental degradation that is not articulated within various eco-theologians’ strategies towards care for the environment in a neo-colonial context in South Africa. The article argues that such a deficiency in eco-theological literature needs some attention to address the future black youth’s contribution to a friendlier environment. The author therefore suggests a ‘missional consciousness’ for one of the strategies for black youth in the quest for the black youth’s participation in environmental care.Contribution: This article contributes to the broader discourses on ecotheology. It affirms the contributions on human beings’ role towards the environment, but further highlights the inequality among human beings in neo-colonial context and how ecotheology should approach the ecological crisis with consideration to such a context. Therefore, the contribution brings into dialogue the post-colonial discourse, specifically the discourse of black consciousness, in relation to a missional consciousness in resolving the ecological crisis through the participation of church youth. Ecotheology has not specifically considered the notions of ‘missional consciousness’ and ‘black consciousness’ in its discourse on protection of the environment. The author relates this discussion specifically to church youth. (shrink)

This review article engages with a rich field of scholarship on logistics that has gathered momentum over the past decade, focusing on two new publications by Laleh Khalili and Martín Arboleda. It contextualizes how and why logistics is bound up with the militarization of contemporary political and social life. I argue that the later 20th century rise of logistics can be better understood as both a response to and symptom of capitalist crisis and I situate this scholarship on war and (...) logistics in relationship to Giovanni Arrighi’s account of crisis and ‘unravelling hegemony’. I also show how logistics provides essential critical and visual resources that contribute to efforts to map global capitalism and to debates on totality and class composition in contemporary critical theory. Finally, contemporary events such as the ongoing Coronavirus crisis and the reemergence of Black Lives Matter are considered in light of this analysis with reference to the centrality of logistics to racial capitalism.

Taking the formal analogies between black holes and classical thermodynamics seriously seems to first require that classical thermodynamics applies in relativistic regimes. Yet, by scrutinizing how classical temperature is extended into special relativity, I argue that the concept falls apart. I examine four consilient procedures for establishing the classical temperature: the Carnot process, the thermometer, kinetic theory, and black-body radiation. I argue that their relativistic counterparts demonstrate no such consilience in defining the relativistic temperature. As such, classical temperature (...) doesn’t appear to survive a relativistic extension. I suggest two interpretations for this situation: eliminativism akin to simultaneity, or pluralism akin to rotation. (shrink)

South African missiology has seen a shift in its praxis since the late 20th century. David J. Bosch made a crucial contribution in this regard. The shift includes mission as a contextualised praxis and agency. In mission studies, agency has become necessary in postcolonial mission, primarily because of the loss of identity of the oppressed in colonised countries. Through contextual theologies of liberation, African theology, Black Theology of Liberation and postcolonial studies, theologians were able to reflect on the human (...) dignity of the colonised. However, there are still significant efforts needed in this quest, and therefore, the praxis cycle used in missiology is useful to also assess effects on the oppressed and marginalised through the emerging context of the Fourth Industrial Revolution (4IR). In the task of doing mission in the world differently, the questions that missiologists ask are important. The emergence of the 4IR aims to merge the biological with the technological and will bring more challenges to mission work in Africa. This will bring upon us the responsibility to reflect on the notion of human agency, the theologies espoused in such a time and missiologists’ contextual lenses and strategies employed. These should have to be carefully considered especially in a post-apartheid context. The researcher will, therefore, use the commonly used praxis cycle in missiological research to explore through a Socratic (questioning) approach what the implications will be for missiologists and mission agents in the quest of transforming church and the post-apartheid society.Contribution: Though there has emerged a few theological contributions from missiology, there has not been a missiological contribution on the 4IR. The author therefore uses one of the theological methods in the discipline to put on the table the imperative questions that those doing missiological research should pose in the context of the 4IR.

Essays, articles, artworks, and documents taken from and inspired by the symposium on Reza Negarestani's Cyclonopedia: Complicity with Anonymous Materials, which took place in March 2011 at The New School. Hailed by novelists, philosophers, artists, cinematographers, and designers, Cyclonopedia is a key work in the emerging domains of speculative realism and theory-fiction. The text has attracted a wide-ranging and interdisciplinary audience, provoking vital debate around the relationship between philosophy, geopolitics, geophysics, and art. At once a work of speculative theology, a (...) political samizdat, and a philosophic grimoire, Cyclonopedia is a Deleuzo-Lovecraftian middle-eastern Odyssey populated by archeologists, jihadis, oil smugglers, Delta Force officers, heresiarchs, and the corpses of ancient gods. Playing out the book's own theory of creativity - "a confusion in which no straight line can be traced or drawn between creator and created - original inauthenticity" - this multidimensional collection both faithfully interprets the text and realizes it as a loving, perforated host of fresh heresies. The volume includes an incisive contribution from the author explicating a key figure of the novel: the cyclone.

Pathologizing Black Bodies reconsiders the black body as a site of cultural and corporeal interchange; one involving violence and oppression, leaving memory and trauma sedimented in cultural conventions, political arrangements, social institutions and, most significantly, materially and symbolically engraved upon the body, with "the self" often deprived of agency and sovereignty. Consisting of three sections, this text focuses on works of the 20th and 21st century fiction and cultural narratives by mainly African American authors, aiming to highlight the (...) different ways in which race has been pathologized in America and examine how the legacies of plantation ideology have been metaphorically inscribed on black bodies. The variety of analytical approaches and thematic foci with respect to theories and discourses surrounding race and the body allow us to delve into this thorny territory in the hope of gaining perspectives about how African-American lives are still shaped and haunted by the legacies of plantation slavery. Furthermore, this volume offers insights into the politics of eugenic corporeality in an illustrative dialogue with the lasting carceral and agricultural effects of life on a plantation. Tracing the degradation and suppression of the black body, both individual and social, this text includes analysis of the pseudo-scientific discourse of social Darwinism and eugenics; the practice of mass incarceration and the excessive punishment of black bodies; and food apartheid and USDA practices of depriving black farmers of individual autonomy and collective agency. Based on such an interplay of discourses, methodologies and perspectives, this volume aims to use literature to further examine the problematic relationship between race and the body and stress that black lives do indeed matter in the USA.

In lieu of an abstract, here is a brief excerpt of the content:EugenicsMary Carrington Coutts (bio) and Pat Milmoe McCarrick (bio)The word eugenics (from the Greek eugenes or well-born) was coined in 1883 by Francis Galton, an Englishman and cousin of Charles Darwin, who applied Darwinian science to develop theories about heredity and good or noble birth (I, Kevles 1985, p. x).The entry under "eugenics" in the Encyclopedia of Bioethics notes that the term has had different meanings in different eras: (...) "a science that investigates methods to ameliorate the genetic composition of the human race; a program to foster such betterment; a social movement; and in its perverted form, a pseudo-scientific retreat for bigots and racists" (V, Ludmerer 1978, p. 457). Kevles, who places a stronger emphasis than Ludmerer on the degeneration of eugenics, says that by 1935 it "had become 'hopelessly perverted' into a pseudoscientific facade for 'advocates of race and class prejudice, defenders of vested interests of church and state, Fascists, Hitlerites, and reactionaries generally'" (I, Kevles 1985, p. 164).Phrases such as "survival of the fittest" and "struggle for existence" came into use at the end of the nineteenth century when eugenics societies were created throughout the world to popularize genetic science. "Negative eugenics" utilized marriage restriction, sterilization, or custodial commitment of those thought to have unwanted characteristics. "Positive eugenics" tried to encourage the population perceived as "superior" to have more offspring (V, Ludmerer 1978, p. 459).In the United States, after World War I, new information, such as the importance of environmental influences and the more complex concept of multi-gene effects in inheritance, diminished the scientific justification for eugenics, but this knowledge did not decrease the pressure for legislation, judicial action, or immigration controls. The U.S. Immigration Restriction Act of 1924 favored immigration from northern Europe and greatly restricted the entry of persons from other areas referred to as "biologically inferior." Between 1907 and 1937, 32 [End Page 163] states required sterilization of various citizens viewed as undesirable: the mentally ill or handicapped; those convicted of sexual, drug, or alcohol crimes; and others viewed as "degenerate" (V, Larson 1991).In Germany, interest in eugenics flourished after the turn of the century when Dr. Alfred Ploetz founded the Archives of Race-Theory and Social Biology in 1904 and the German Society of Racial Hygiene in 1905. The German term Rassenhygiene or race hygiene encompassed more than the word "eugenics;" it included all attempts to improve hereditary qualities as well as measures directed at population increase (III, Weiss 1987). By the 1920s, various German textbooks incorporated ideas of heredity and racial hygiene, and German professors were participating in the international eugenics movement. The Kaiser Wilhelm Institute of Anthropology, Human Heredity, and Eugenics was founded in 1927; by 1933 a sterilization law, the Law for the Prevention of Congenitally Ill Progeny, which originally was entitled "Eugenics in the Service of Public Welfare," indicated compulsory sterilization "for the prevention of progeny with hereditary defects" in cases of "congenital mental defects, schizophrenia, manic-depressive psychosis, hereditary epilepsy... and severe alcoholism." (III, Müller-Hill 1988, p. 10).The co-mingling of science, politics, and Weltanschauung (ideological or religious world view) caused the darkest period for eugenics when Nazi Germans embarked on their "final solution" to the Jewish "problem", or the Holocaust. The Nazi racial-hygiene program began with involuntary sterilizations and ended with genocide. Beginning with the 1933 Law for the Prevention of Congenitally Ill Progeny, 350,000 schizophrenic and other mentally ill persons were involuntarily sterilized, and marriage or sexual contact between Jews and other Germans was banned. Several hundred black children and 30,000 German Gypsies were sterilized. By 1945, when the allies liberated those remaining in Nazi concentration camps, six million Jews, 750,000 Gypsies, and 70,000 German psychiatric patients had been killed by the Nazis (III, Müller-Hill 1992, p. 47). As a result of the German experience, eugenic thought dropped to its nadir, and to the present day, the term "eugenics" invokes a sense of horror in some people.Great Britain, the United States, and Germany were the countries most involved with eugenic science in the first half of this century, but interest was present in Europe and other...

The existing research on the role of intellectuals in alleviating suffering has overlooked contributions by prominent Black intellectuals from the United States in the early 1990s. Two roundtable debates co-organised under the auspices of the Boston Review at Harvard and MIT in 1992 and 1993 in response to Eugene Rivers’ essay “On the Responsibility of Intellectuals in the Age of Crack” were central to these contributions, counting a star-studded line-up of Black intellectuals including bell hooks, Cornel West, (...) and Glenn Loury. Participants explore the role of Black intellectuals in the US, debating what they can and should do to combat oppression and domination. In this article, I recover the context of the debates, reconstruct their arguments, and make a case for their major historical and political significance. I comparatively interpret the two roundtables, identifying three major points of convergence. First, participants begin from a Gramscian conception of organic intellectuals, developing this further to defend the need for collective intellectual praxis. Second, the race-class-gender nexus plays a central role in structuring the very possibility of intellectuals affecting social change. Third, these intellectuals subscribe to a significantly pessimistic action paralysis, indicative of the relative powerlessness of intellectual debate in addressing structural oppression. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Black Health: The Social, Political, and Cultural Determinants of Black People's Health by Keisha RayChioma Dibia (bio)Black Health: The Social, Political, and Cultural Determinants of Black People's Health by Keisha Ray New York: Oxford University Press, 2023Prior to the COVID-19 pandemic, bioethics had engaged only sparingly with the concept of racism. In 2016, Danis and colleagues published an article exhorting bioethicists to engage more (...) meaningfully with the concept of racism—given its impact on health and well being—and to consider strategies for combating it within and outside clinical settings (Danis et al. 2016, 5). While this paper generated considerable debate regarding how far bioethics ought to go in its engagement with racism (Baker 2016, 16; Weddle 2016, 32; Fuller 2016, 29), the focus of the field of bioethics quickly turned to more traditional subjects of bioethical inquiry, including ethical issues arising in doctor-patient relationships and new reproductive technologies. However, since the COVID-19 pandemic and the murder of George Floyd during that time, racism has received greater attention in the bioethics literature and Keisha Ray's Black Health arrives just in time to urge us to ensure that the current focus on the impact of racism on the health of racially minoritized people is not short-lived (Ray 2023, 21; BBC News 2020).The overarching argument in Ray's Black Health is that Black people's poor health does not arise from innate biological deficiencies but stems from their experience of racism at the structural, institutional, and interpersonal levels. Ray stresses that far from being solely a feature of America's past, racism [End Page 105] continues to taint Black people's relationship with the healthcare system and other societal institutions. In each chapter, Ray focuses on a specific racial disparity in health to illustrate how racism limits Black people's access to the social determinants of health and thereby contributes to their poor health. To set the context for this discussion, Ray provides an introductory chapter where she unpacks key terms including "racism," "racial disparities," and "the social determinants of health." In this chapter, Ray also clearly outlines the structure of the text and provides a summary of each chapter. This chapter provides the blueprint for the rest of the book, as in it, Ray provides a clear statement of the style, content, and purpose of Black Health.The first racial disparity that Ray considers is Black birthing mortality, and in chapter 1, Ray traces this to the history of slavery and eugenic policies which have shaped the relationship between physicians and Black women. As Ray explains, since Black people were forcibly brought to the United States, the government has sought to control Black women's reproductive lives and has often relied on physicians to effect control. She demonstrates how harmful stereotypes about Black women, including their so-called hardiness, originated in medical literature and have been used to deny pregnant Black women humane care. According to Ray, "[c]linicians' attitude and behaviors towards Black pregnant people still reflect an enslaved and slave-owner mentality, and this has great consequences for the survival of Black pregnant people." (32) By highlighting the birthing experiences of Serena Williams and Shalon Irving, Ray dispels the assumption that wealth or academic qualifications are a panacea for Black birthing mortality and shows how racism can be deadly for all Black pregnant women, irrespective of socioeconomic status. Ray also considers how income and housing inequities affect Black pregnant women and the cumulative effect of weathering on their health as well as that of their unborn children. This chapter most clearly shows how interpersonal, institutional, and structural racism operate and intersect to render pregnancy and childbirth a potentially dangerous experience for Black women.Next, Ray turns to racial disparities in clinical pain management and continues to explore the impact of historically racist beliefs and false stereotypes on the care of Black people. However, in this second chapter, Ray delves more deeply into the role of medical literature—both historical and contemporary sources—in perpetuating false assumptions about the Black body. She demonstrates how the historical portrayal of the Black body as not only less than human... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Hope Draped in Black: Decolonizing Utopian StudiesCaroline Edwards (bio)What does utopian studies have to learn from critical race theory, Black studies, and ideas of Black futurity? While utopian scholars have begun unpicking the colonial entanglements of utopianism’s origins (particularly as a literary genre grounded in pelagic crossings to the New World that have advocated slavery, extractivism, and eugenics to name a few notable examples across the (...) utopian canon), few, if any, have incorporated the perspectives, aesthetics, and theoretical work of Black scholars themselves.1 The following are a few brief remarks organized around keywords (in a nod to Raymond Williams, a fierce advocate of utopian thinking) that attempt to sketch an answer to these questions, with a focus on my own area of utopian study: utopian literary and cultural production in the contemporary period.ProgressWe might start by considering the literary utopia’s most prolific period, from roughly 1880 to 1915. In a deluge of utopian narratives, many of them penned by amateur writers, we find the emergence of a genre that is thoroughly [End Page 498] rooted in industrialized progress. Whatever their perspective on capitalism and waged labor, these works privilege advanced industrialization as the primary means to eliminate poverty and disease, thereby liberating workers into automated futures of post-scarcity abundance. Examples include Edward Bellamy’s highly rationalized system of pneumatic delivery (Looking Backward: 2000–1887 [1888]), Mary E. Bradley Lane’s chemical production of food from waste products (Mizora: A World of Women [1890] 1999), H. G. Wells’s titanic hydro-powered engineering (Men Like Gods [1923]), Edward Bulwer Lytton’s lithic limitless energy, Vril (The Coming Race [1871]), or the ubiquitous electricity that powers Elizabeth Burgoyne Corbett’s clean city (New Amazonia: A Foretaste of the Future [1899] 2011), Alice Ilgenfritz Jones and Ella Marchant’s advanced Martian society (Unveiling a Parallel: A Romance [1893]), and Alexander Bogdanov’s advanced scientific culture on the red planet (Красная звезда [Red Star (1908) 1984]). Indeed, many notable dystopian novels begin with the same premise of highly automated societies that focus, rather, on the awfulness of life without purpose (Anna Bowman Dodd’s The Republic of the Future; Or, Socialism a Reality [1887], E. M. Forster’s “The Machine Stops” [1909], Kurt Vonnegut’s Player Piano [1952]). While they are far from uncritical of the telos of historical progress (most of the works highlight the class and gender inequalities of their own time), utopian novels in this period tend to view the utopian process as one of harnessing historical progress in a more equitable direction; they rarely question the Hegelian premise that history moves through contradictory forces in a dialectical series of stages.In his 2016 book Hope Draped in Black, Joseph R. Winters explores the lasting damage that ideas of historical progress have wrought on Black writers, artists, and thinkers. While notions of racial uplift are loaded with a linear narrative of Black progress such conceptions, he writes, “are mediated by melancholy, loss, and a recalcitrant sense of tragedy” (6–7). Building on Adorno and Horkheimer’s landmark critique in Dialectic of Enlightenment (1944) as well as the works of W. E. B. Du Bois, Winters notes thatmodern notions of progress and freedom are inherently flawed and problematic because they rely on and are intertwined with practices and conditions—capitalism, colonial expansion, racial hierarchies, endeavors, and incentives to usurp and possess that earth—that are harmful to non-Europeans, working-class bodies, women, and other groups.(2016, 8) [End Page 499]Examining the relationship between melancholy and hope in Black literary and aesthetic traditions, Winters explores how writers such as Toni Morrison and Ralph Ellison incorporate jazz into their works, using its discordant, improvisational structures to imagine time out of joint (the Derridean deferral of justice announced by the arrival of the specter of old King Hamlet, who returns) (Derrida 1994). Here, Winters writes, “the past can always haunt and disturb the present [so that] the present is always a site of potential breaks and ruptures that can signify both dislocation and pain as well as novelty and possibility” (2016, 25). If we are to contemplate the almost overwhelming task of decolonizing utopian studies, then... (shrink)

Eugene 'Gene' Vernier worked as a fashion photographer for British Vogue from 1954 to 1967, during one of the most exciting periods in fashion history. Shooting of-the-moment looks from the likes of Christian Dior and Emilio Pucci and top models including Celia Hammond, Jean Shrimpton, and current Vogue creative director Grace Coddington, Vernier worked with some of the biggest names in the industry. Yet he was relatively unconcerned with celebrity. Interested only in bringing out the very best in each (...) frame, Vernier was a true craftsman in the fashion photography trade. Featuring more than one hundred of Vernier's own favorite photographs drawn from Vogue's extensive photo archive, this lavishly illustrated volume reveals remarkable innovation in the use of props, backdrops, and location. Whether he was photographing his subjects by the sea, with a canine companion, or perfectly positioned atop a pale pink convertible, Vernier's careful composition enhanced the essence of his subject. Vernier shot mostly in black-and-white, and his trademark “look” is one of classic femininity. He sought to capture models when they were relaxed, enjoying the clothing, and confident that their photographer would show both only at their best. Providing commentary on the photographs are fashion history expert Becky Conekin and Vogue historian Robin Muir. This is first book to focus on Vernier's work at Vogue and it allows readers a rare glimpse of his inimitable blend of technical excellence and an eye for experimentation. (shrink)

Between 1917 and 1935, William Carlos Williams’ poetic style shifted from a focus on color to a verbal grayscale of photorealism. Considering this shift alongside of the historical connection between photography and eugenics raises questions about Williams’ status as a physician during an era when medical discourse was dominated by theories of scientific racism. While one might conclude that Williams move from color to grayscale represents a capitulation to public health anxieties regarding the pathologized bodies of the immigrant poor, I (...) argue that it is precisely through his adoption of black-and-white photorealism that Williams overturns hereditary notions of degeneracy.

The calibration solution to the stability of the world despite eye movements depends, according to Bridgeman et al., upon a combination of three factors which presumably all need to operate to achieve the goal of stability. Although the authors admit (sect. 4.3, para. 5) that the relative contributions of retinal and extraretinal factors will depend on the particular viewing situation, Figure 5 (sect. 4.3) makes it clear in its representation that the role of perceptual factors is relatively minor compared to (...) extraretinal ones. It is with this representation that this commentary wishes to take issue, believing that it occurs as a result of some assumptions about terminology that may be ambiguous, as well as some misconceptions about the circumstances in which there is a need for stability.

Multi-level selection can be understood via the Price equation or contextual analysis, which offer incompatible statistical decompositions of evolutionary change into components of group and individual selection. Okasha argued that each approach suffers from problem cases. I introduce further problem cases for the Price approach, arguing that it is appropriate for MLS 2 group selection but not MLS 1. I also show that the problem cases Okasha raises for contextual analysis can be resolved. For some such cases, however, it emerges (...) that there is no determinate answer to the question of how much of the total selective effect was due to group selection compared to individual selection. This suggests that when there is interaction between the effect of group character and individual character, one cannot separate selection into distinct ‘levels’ at all. (shrink)

In this article, ideas from St. Thomas Aquinas's neo-Aristotelian philosophy pertaining to the nature of human existence are used to arrive at a metapsychological orientation to child psychology. Four primary characteristics were identified as being fundamental to a Thomistic perspective on child development: anthropological holism, vitalistic integrative development, inherent sociality, and tactile interpersonal relatedness. These characteristics served as guiding themes for the articulation of a succinct, coherent narrative describing the nature of a Thomistic child psychology. Developmental insights from the works (...) of several psychologists were used to assist in the creation of this narrative. Associated characteristics of a Thomistic perspective on child psychology and some remarks concerning the future development of such an approach are provided at the conclusion of this analysis. 2012 APA, all rights reserved).

A simple quantum relativistic model of ν µ − ντ neutrino oscillations in the OPERA experiment is presented. This model suggests that the two components in the neutrino beam are separated in space. After being created in a meson decay, the µ-neutrino moves 18 meters ahead of the beam’s center of energy, while the τ -neutrino is behind. Both neutrinos have subluminal speeds, however the advanced start of the ν µ explains why it arrives in the detector 60 ns earlier (...) than expected. Our model does violate the special-relativistic ban on superluminal signals. However, usual arguments about violation of causality are not applicable here. The invalidity of standard special-relativistic arguments is related to the interaction-dependence of the boost operator, which implies that boost-transformed space-time coordinates of events with interacting particles do not obey linear and universal Lorentz formulas.

TeSelle examines the theme of St. Augustine's "two cities" against the background of the ancient world's civic vision, with the polis as the chief model for political life. Against most interpreters' assumptions, TeSelle shows that the sojourner, while not fully at home in the earthly city, is nowhere understood as an "alien" and thus has certain rights and responsibilities in the earthly city.

In recent years, philosophers have developed a novel conception of blame as a kind of moral protest. This Protest View of Blame faces doubts about its intelligibility: can we make sense of inner ‘protest’ in cases of unexpressed blame? It also faces doubts about its descriptive adequacy: does ‘protest’ capture what is distinctive in reactions of blame? I argue that the Protest View can successfully answer the first kind of doubt, but not the second. Cases of contemptful blame and unexpressed (...) blame offer initial counterexamples to the view. The Protest View can accommodate these examples by appealing to a broader notion of protest, but, I argue, at the cost of retreating to a broader category that no longer captures what is distinctive about blame. Moreover, nonviolent resistance, in the tradition of Gandhi and Dr. King, characteristically protests without blame, presenting another powerful challenge to the Protest View. These challenges, I argue, undermine the view, while helping to illuminate and defend the appeal of nonviolent resistance. They also offer an alternative conception of the relation between protest and blame, characteristic of nonviolent resistance and obscured by the Protest View. On that alternative, the relation is not descriptive but practical; rather than understanding blame as a kind of protest, we should aim, in many cases, to replace blame with protest. (shrink)

Thomas Hobbes’s infamously severe accounts of the phenomenon of laughter earned the condemnation of such varied readers as Francis Hutcheson and Friedrich Nietzsche, and he has maintained his reputation as an enemy of humor among contemporary scholars. A difficulty is raised by the fact that Hobbes makes ample use of humor in his writings, displaying his willingness to evoke in his readers what he appears to condemn. This article brings together Hobbes’s statements on laughter and comedic writing with examples of (...) his own humorous rhetoric to show that Hobbes understands laughter as a species of insult, but that there are conditions under which humor can be made to serve the cause of peace. Drawing on evidence from across Hobbes’s works, and in particular from an understudied discussion of “Vespasian’s law” in the Six Lessons, this essay theorizes the conditions under which Hobbes found witty contumely to be conducive to peace. On this reading, Hobbes models the discreet use of humorous rhetoric in defense of peace, a defense that will be ongoing even after the commonwealth has been founded. Hobbes offers insight into how we can remain attuned to laughter’s inegalitarian tendencies without foregoing the equalizing potential to be found in laughing at ourselves and at those who think too highly of themselves.

Project Chariot, one of the first planned nuclear excavation experiments of the Atomic Energy Commission’s Plowshare program, touched off a controversy over its safety that drew in two prominent American biologists, Paul Sears and Barry Commoner, both now known mainly for their roles as environmental advocates. However, Sears, the ecologist and well-established conservationist, supported Project Chariot and the Plowshare program in general, while Commoner, unacquainted with ecology at the time, strongly opposed it. A close study of their different responses to (...) this project provides insights into the tensions and pressures on scientists during this critical period of the Cold War, 1960–1961, when fear of nuclear war and concerns over radioactive fallout from bomb tests mixed with hopes for peaceful applications of nuclear energy and the environmental movement had not yet begun. For Sears, the close connections in the United States between the science of ecology and the Atomic Energy Commission may well have played a significant role in his support for Chariot, while for Commoner, Project Chariot turned out to be his epiphany moment, the incident that transformed him from an antinuclear activist into an environmentalist.

Through much of the eighteenth and nineteenth centuries in Britain, natural theology referred to the traditional arguments for the existence of God, particularly as put forth in the work of William Paley. But developments in the empirical sciences and in the empirical type of philosophy which dominated British thought during this period challenged these arguments and led to widespread religious (...) skepticism. Thomas Reid and William Hamilton were two Scots who had sought to overcome the religious skepticism of the empirical age, but the appeal to common sense belief on the one hand and to an unknowable absolute on the other hand provided little comfort for many who were dissatisfied with the options of religious scepticism and doctrinal orthodoxy.
