Patients with behavioral variant of frontotemporal dementia (FTD) have difficulties recognizing facial emotions, a deficit that may contribute to their impaired social skills. In three experiments, we investigated the FTD deficit in recognition of facial emotions, by comparing six patients with impaired social conduct, nine Alzheimer’s patients, and 10 age-matched healthy adults. Experiment 1 revealed that FTD patients were impaired in the recognition of negative facial emotions. Experiment 2 replicated these findings when participants had to determine whether two faces were (...) expressing the same or different emotions. Experiment 3 was a control study in which participants had to discriminate whether two faces were of the same sex. In this non-emotional processing task, both patient groups performed worse than normal participants, but FTD patients performed as well as Alzheimer’s patients. We conclude that FTD patients are impaired in the recognition of negative facial emotions. © 2005 Elsevier Ltd. All rights reserved. (shrink)

This study explored possible deficits in selective attention brought about by Dementia of Alzheimer Type (DAT). In three experiments, we tested patients with early DAT, healthy elderly, and young adults under low memory demands to assess perceptual filtering, conflict resolution, and set switching abilities. We found no evidence of impaired perceptual filtering nor evidence of impaired conflict resolution in early DAT. In contrast, early DAT patients did exhibit a global cost in set switching consistent with an inability to maintain the (...) goals of the task (mental set). We discuss these findings in relation to the DAT literature on executive attention, dual-tasking, and working memory. Ó 2007 Elsevier Inc. All rights reserved. (shrink)

ABSTRACT:It may be too late to avoid the climate crisis, likely to be humanity's most expensive, widespread, and enduring catastrophe. This is a qualitatively different kind of catastrophe, in which increased costs, decreased revenue, and no possibility of bailout force communities to harshly cut budgets, especially in health care. Little is known about making such brutal cuts fair or efficient, nor how to help the public accept them. The crisis presents an opportunity for bioethicists to play a crucial role, but (...) one for which traditional approaches are inherently inadequate. Although often dismissed as heartless, Garrett Hardin's "lifeboat ethics" started a conversation about making ethical choices in global disasters—where all options are painful and unacceptable—and may provide guidance. Bioethics during the climate crisis must focus on communities rather than individuals and help survivors grieve the terrible consequences. Because today's choices will affect many generations, with the burdens falling most heavily on poor communities, we have to construct a radical bioethics to help tomorrow's health care become green, efficient, and fair.

With chapters that undertake ideological critiques of education, religion, the politics of reparations, and the problematics of black radical politics in contemporary culture and society, Du Bois's Dialectics employs Du Bois as its critical theoretical point of departure and demonstrates his contributions to, as well as contemporary critical theory's connections to, critical pedagogy, sociology of religion, and reparations theory. Rabaka offers the first critical theoretical treatment of the W. E. B. Du Bois-Booker T. Washington debate, which lucidly highlights Du (...)

BackgroundIn the Canadian Alliance for Healthy Hearts and Minds cohort, participants underwent magnetic resonance imaging of the brain, heart, and abdomen, that generated incidental findings. 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 were recruited with (...) a follow-up questionnaire administered to 909 participants 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% of participants, with the highest proportions found in the brain and abdomen. The majority of participants 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 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)

One staple of living in our information society is having access to the web. Web-connected devices interpret our queries and retrieve information from the web in response. Today’s web devices even purport to answer our queries directly without requiring us to comb through search results in order to find the information we want. How do we know whether a web device is trustworthy? One way to know is to learn why the device is trustworthy by inspecting its inner workings, 156–170 (...) 1995; Humphreys 2004, Episteme, 6, 221–229 2009). But ordinary users of web devices cannot inspect their inner workings because of their scale, complexity, and the corporate secrecy which enshrouds both the procedures by which the devices operate and the companies that make them. Further piling on this predicament, authors have criticized web technology on the grounds that the invisibility of the web devices’ inner workings prevents users from critically assessing the procedures that produce a given output, in some cases, barring users from fulfilling their epistemic responsibilities, 343–355 2010; Miller and Record Episteme, 10, 117–134 2013). I consider four broad kinds of reasons which we can acquire without inspecting the inner workings of black-boxed technology: individual understanding, expert testimony, testing through experience, and social vetting; and show how each is a viable method of appraising black-boxed technology. By deploying these methods, we can remain responsible inquirers while nonetheless benefitting from today’s epistemic resources on the web. (shrink)

ABSTRACT This article will examine the career of weaver and occupational therapist Mary E. Black by using her life as a lens through which to explore the intersection of arts and crafts revivalism with occupational therapy in early twentiethcentury northeastern North America. Born in Massachusetts, Black grew up in and was educated in Wolfville, Nova Scotia. She trained as ward's aide in Montreal in 1919 and worked in a string of hospitals and sanitariums throughout the United States and (...) Nova Scotia. Indeed, Black understood her work as an occupational therapist and what she described as “the therapeutics of weaving” to be intertwined. Like many arts and crafts revivalists of her period, Black saw the teaching of skilled craftmaking as a means to generate self-sufficiency, since it provided a way for displaced and injured people to make salable goods in the face of industrialization, war, and inadequate medical care. In Black's case, the utopian social mission of the new professional field of occupational therapy provided just the institutional means to disseminate the remunerative qualities of craftwork on a broad scale.

By combining a flanker task and a cuing task into a single paradigm, the authors assessed the effects of orienting and alerting on conflict resolution and explored how normal aging and Alzheimer’s disease (AD) modulate these attentional functions. Orienting failed to enhance conflict resolution; alerting was most beneficial for trials without conflict, as if acting on response criterion rather than on information processing. Alerting cues were most effective in the older groups— healthy aging and AD. Conflict resolution was impaired only (...) in AD. Orienting remained unchanged across groups. These findings provide evidence of different life span developmental and clinical trajectories for each attentional network. (shrink)

Machine learning algorithms may radically improve our ability to diagnose and treat disease. For moral, legal, and scientific reasons, it is essential that doctors and patients be able to understand and explain the predictions of these models. Scalable, customisable, and ethical solutions can be achieved by working together with relevant stakeholders, including patients, data scientists, and policy makers.

Black holes are arguably the most extraordinary physical objects we know in the universe. Despite our thorough knowledge of black hole dynamics and our ability to solve Einstein’s equations in situations of ever increasing complexity, the deeper implications of the very existence of black holes for our understanding of space, time, causality, information, and many other things remain poorly understood. In this paper I survey some of these problems. If something is going to be clear from my (...) presentation, I hope it will be that around black holes science and metaphysics become more interwoven than anywhere else in the universe. (shrink)

In The Souls of Black Folk, W.E.B. Du Bois introduces double consciousness as a result of racial prejudice and oppression. Explained as a state of confliction felt by black Americans, Du Bois presents double consciousness as integral to understanding the black experience. Later philosophers question the importance of double consciousness to current race discussions, but this paper contends that double consciousness provides valuable insights into black and white relations. To do this, I will utilize the modern (...) slang term, “Oreo,” to highlight how a perceived incompatibility between blacks and whites could prevent America from achieving a greater unity. (shrink)

This book brings a new understanding to one of the great documents of American and black history. While most scholarly discussions of The Souls of Black Folk focus on the veils, the color line, double consciousness, or Booker T. Washington, this book reads Du Bois' work as a profoundly nuanced interpretation of the souls of black Americans at the turn of the twentieth century. Demonstrating the importance of the work as a socioh-istorical study of black life (...) in America at the turn of the twentieth century and offering new ways of thinking about many of the topics introduced in Souls, this book charts Du Bois' successful appropriation of Hegelian idealism in order to add America, the nineteenth century, and black people to the historical narrative in Hegel's philosophy of history. It adopts Du Bois' point of view to delve into the social, cultural, political, and intellectual milieus that helped to create The Souls of Black Folk. (shrink)

When the character of Black Panther first appeared in Fantastic Four no. 52 in July 1966, legendary creators Stan Lee and Jack Kirby didn't just write a story about another hero with extraordinary powers, they birthed the first Black superhero. For Lee, "it was a very normal thing," because "A good many of our people here in America are not white. You've got to recognize that and you've got to include them whatever you do." While it might've seemed (...) normal to Lee, Black Panther's (and Wakanda's) significance cannot be overstated. After all, the first Black superhero isn't just a Black superhero, he's the King of an African nation endowed with otherworldly powers, and Wakanda isn't just an African nation, it's the most advanced civilization the Earth has ever seen. Indeed, it shouldn't be lost on us that when Black Panther was introduced (during the Civil Rights era of the 1960s) the thought of a Black President-or an advanced, futuristic African society-would have been, well, unthinkable for too many people.

The Nation of Islam has intrigued American society since its inception in 1930. Historically, the religio-nationalist organization has been the object of admiration for its uncanny ability to reform the lives of downtrodden blacks. At the same time, the NOI has garnered condemnation for the controversial, racialized and divisive doctrine that it espouses. This condemnation has led to a dismissal of the NOI’s doctrine as reactionary, bigoted, and fanciful myth-making. In recent decades however, scholars have begun interrogating the doctrine of (...) the NOI. Rather than dismissing it, scholars in various fields have recognized the critical and phenomenological nature of its doctrine as it goes about the “mental, physical, and spiritual resurrection” of black Americans. In this article, I interrogate three of the most controversial claims of the NOI: The White man is the devil, the Black man is God, and its endorsement of the separation of Blacks into their own territory. Viewed through the lens of phenomenology, I submit that the NOI’s doctrine and actions should be viewed as the establishment of an emancipative and recuperative “Phenomenology of Blackness” that counters a lifeworld built upon the disembodiment and dehumanization of Black bodies. Reframing the NOI’s doctrine in this way positions it as a linguistic, religiously stylized, praxis-oriented critical hermeneutic phenomenology. (shrink)
