Various publications claim that medical AI systems perform as well, or better, than clinical experts. However, there have been very few controlled trials and the quality of existing studies has been called into question. There is growing concern that existing studies overestimate the clinical benefits of AI systems. This has led to calls for more, and higher-quality, randomized controlled trials of medical AI systems. While this a welcome development, AI RCTs raise novel methodological challenges that have seen little discussion. We (...) discuss some of the challenges arising in the context of AI RCTs and make some suggestions for how to meet them. (shrink)

Despite the resistance from radical antiracist formations, autonomously organised by racialized minorities and migrants themselves, that can be witnessed in many spaces, the success with which antiracism has been both appropriated and relativized by the state as well as hegemonic activist voices poses a significant threat. The politics of diversity and the consensus around the notion that western societies are post-race contribute to portraying the critique of racism from people of colour as inaccurate, alienating and counter-productive to the achievement of (...) social cohesion. The necessity of dismantling the idea of race as suggested by antiracist activists and scholars has been subverted in the deconstruction of the experience of racism by an ‘antiracialist’—rather than a more radical antiracist—agenda intent on relativizing the struggle against racism as one among many. The consequence of this in the context of postracialism is for racism itself to be departicularized and dissociated from its historical roots. Antiracism needs to reclaim the risk, that Goldberg argues is inherent to it, and rescue it from being universalised into meaninglessness. (shrink)

Popper argued that a statistical falsification required a prior methodological decision to regard sufficiently improbable events as ruled out. That suggestion has generated a number of fruitful approaches, but also a number of apparent paradoxes and ultimately, no clear consensus. It is still commonly claimed that, since random samples are logically consistent with all the statistical hypotheses on the table, falsification simply does not apply in realistic statistical settings. We claim that the situation is considerably improved if we ask a (...) conceptually prior question: when should a statistical hypothesis be regarded as falsifiable. To that end we propose several different notions of statistical falsifiability and prove that, whichever definition we prefer, the same hypotheses turn out to be falsifiable. That shows that statistical falsifiability enjoys a kind of conceptual robustness. These notions of statistical falsifiability are arrived at by proposing statistical analogues to intuitive properties enjoyed by exemplary falsifiable hypotheses familiar from classical philosophy of science. That demonstrates that, to a large extent, this philosophical tradition was on the right conceptual track. Finally, we demonstrate that, under weak assumptions, the statistically falsifiable hypotheses correspond precisely to the closed sets in a standard topology on probability measures. That means that standard techniques from statistics and measure theory can be used to determine exactly which hypotheses are statistically falsifiable. In other words: the proposed notion of statistical falsifiability both answers to our conceptual demands and submits to standard mathematical techniques. (shrink)

Face à l’extension d’un art disséminé, nous nous arrêtons sur un registre de pratiques et de notions malentendues, les arts martiaux japonais, confondus avec des « sports de combat ». Par « art » nous entendons une conduite soucieuse de mener une pratique et une production à la perfection, et foncièrement à la perfection de soi, quelle que soit la manière culturelle locale d’envisager cet état d’accomplissement. En regard de l’art du bouquet ( ikebana ), de pratiques shintoïstes (comme le (...) kototama ), nous examinons des notions comme celle d’art martial ou bugei, littéralement l’art ( gei ) d’arrêter la lance ( bu ). Ce que les Occidentaux ont interprété comme un « art de la guerre » se voulait un « art de la paix ». Les arts martiaux japonais mobilisent en ce sens des notions et des expériences parfois connues en Occident comme le ki, l’énergie, ou méconnues comme le shin (le cœur-esprit), le ma (l’espace-temps) ou l’ aï (l’un). Nous nous proposons de démonter un malentendu à partir d’une pratique artistique, le kino-michi, élaboré par Masamichi Noro, dérivée de l’aïkido, en vue de comprendre en quoi ces bugei sont une éducation, une élévation de l’âme et du corps au même titre que la musique ou la danse.

This article argues that, despite the efforts to expunge race from the European political sphere, racism continues to define the sociality of Europe. The post-war drive to replace race with other signifiers, such as culture or ethnicity, has done little to overcome the effects of the race idea, one less based on naturalist conceptions of hierarchical humanity, and more on fundamental conceptions of Europeanness and non-Europeanness. The silence about race in Europe allows European states to declare themselves non-racist, or even (...) anti-racist, while at the same time continuing to imply an inherent European superiority, which determines both international relationships and relationships with those seen as `in but not of Europe' within its domestic spheres. The article concludes by asking what the repercussions of this are in the context of the contemporary discourse on cohesion and integration that replaces multiculturalism as a possible way of living together in a Europe always less homogeneous in reality than it is commonly imagined to be.

Issues of reliability are claiming center-stage in the epistemology of machine learning. This paper unifies different branches in the literature and points to promising research directions, whilst also providing an accessible introduction to key concepts in statistics and machine learning – as far as they are concerned with reliability.

Synchronic norms of theory choice, a traditional concern in scientific methodology, restrict the theories one can choose in light of given information. Diachronic norms of theory change, as studied in belief revision, restrict how one should change one’s current beliefs in light of new information. Learning norms concern how best to arrive at true beliefs. In this paper, we undertake to forge some rigorous logical relations between the three topics. Concerning, we explicate inductive truth conduciveness in terms of optimally direct (...) convergence to the truth, where optimal directness is explicated in terms of reversals and cycles of opinion prior to convergence. Concerning, we explicate Ockham’s razor and related principles of choice in terms of the information topology of the empirical problem context and show that the principles are necessary for reversal or cycle optimal convergence to the truth. Concerning, we weaken the standard principles of agm belief revision theory in intuitive ways that are also necessary for reversal or cycle optimal convergence.

Kelly Aguirre, Phil Henderson, Cressida J. Heyes, Alana Lentin, and Corey Snelgrove engage with different aspects of Robert Nichols’ Theft is Property! Dispossession and Critical Theory. Henderson focuses on possible spaces for maneuver, agency, contradiction, or failure in subject formation available to individuals and communities interpellated through diremptive processes. Heyes homes in on the ritual of antiwill called “consent” that systematically conceals the operation of power. Aguirre foregrounds tensions in projects of critical theory scholarship that aim for dialogue and solidarity (...) with Indigenous decolonial struggles. Lentin draws attention to the role of race in undergirding the logic of Anglo-settler colonial domination that operates through dispossession, while Snelgrove emphasizes the link between alienation, capital, and colonialism. In his reply to his interlocutors, Nichols clarifies aspects of his “recursive logics” of dispossession, a dispossession or theft through which the right to property is generated. (shrink)

This article seeks to re-examine two major assumptions in mainstream anti-racist thought of the post-war era. These are culturalism, on the one hand, and human rights on the other, both of which have been offered as potential solutions to the ongoing problem of racism. I argue that both fail to cope with racism as it has been institutionalized in the political and social structures of European societies because they inaccurately theorize ‘race’. Racism is treated as an individual attitude born of (...) prejudice and ignorance and not as a political project that emerged under specific conditions within the context of the European nation-state. A re-examination of this legacy of modernity and a questioning of the structuring principles of anti-racism is necessary in the current context of racism against migrants, asylum seekers and refugees.

Ockham’s razor is the characteristic scientific penchant for simpler, more testable, and more unified theories. Glymour’s early work on confirmation theory eloquently stressed the rhetorical plausibility of Ockham’s razor in scientific arguments. His subsequent, seminal research on causal discovery still concerns methods with a strong bias toward simpler causal models, and it also comes with a story about reliability—the methods are guaranteed to converge to true causal structure in the limit. However, there is a familiar gap between convergent reliability and (...) scientific rhetoric: convergence in the long run is compatible with any conclusion in the short run. For that reason, Carnap suggested that the proper sense of reliability for scientific inference should lie somewhere between short-run reliability and mere convergence in the limit. One natural such concept is straightest possible convergence to the truth, where straightness is explicated in terms of minimizing reversals of opinion and cycles of opinion prior to convergence. We close the gap between scientific rhetoric and scientific reliability by showing that Ockham’s razor is necessary for cycle-optimal convergence to the truth, and that patiently waiting for information to resolve conflicts among simplest hypotheses is necessary for reversal-optimal convergence to the truth.

How could speaking of oneself be a methodological challenge in the humanities? The paper focuses on cultural studies as a new way of arguing about identity issues. Our thesis is that speaking of oneself entails neither a lack of objectivity nor an overflow of selfishness, but the requirement of self-reflexiveness. As an observer is not neutral but interacts with his field, he thus has to be a aware of his own background and explain it with fairness. So speaking of oneself (...) could be a condition of truth in the humanities. (shrink)

Summary In the 1930s, atomic absorption spectroscopy replaced chemical methods for determining the amount of mercury in atmospheric air. The overall state of chemical analysis was favourable: physical instruments were moving into the chemical laboratory. This new method emerged from work in quantitative physics, and it met a need arising from the risk encountered by those who handled mercury. The new spectrometer, which originally functioned as a detector, also made precise and rapid quantitative determinations possible. This in turn encouraged industrialists (...) to take out patents and make commercial use of the method after various improvements. This method is considered to be the ancestor of modern atomic absorption spectroscopy, which developed independently after 1960. The method developed in the 1930s could only be used for gaseous mercury, and it was not generalized as a method for quantifying other elements. The determination of mercury in air by atomic absorption spectroscopy was the first application of this technique; indeed, it was the only example of a specific use of atomic absorption. It was also part of the instrumental revolution. (shrink)

Le street art a depuis longtemps une réputation de marginalité, lié aux mauvais lieux des esprits contestataires. La critique d’art, savante ou médiatique, abonde en ce sens, perpétuant une image de pratique rebelle et anticonformiste. Toutefois cette marginalité nous semble douteuse compte tenu de l’histoire de ce mouvement, de l’évolution économique et artistique de certaines pratiques de rue, de la reconnaissance d’un art des rues par le marché de l’art et les institutions culturelles privées et publiques. Examinant les statuts d’une (...) marge et du street art depuis des paramètres proprement artistiques et relevant de l’esthétique, notre propos se centrera sur la notion de débordement. (shrink)

We analyze log-data generated by an experiment with Mathtutor, an intelligent tutoring system for fractions. The experiment compares the educational effectiveness of instruction with single and multiple graphical representations. We extract the error-making and hint-seeking behaviors of each student to characterize their learning strategy. Using an expectation-maximization approach, we cluster the students by their strategic profile. We find that a) experimental condition and learning outcome are clearly associated b) experimental condition and learning strategy are not, and c) almost all of (...) the association between experimental condition and learning outcome is found among students implementing just one of the learning strategies we identify. This class of students is characterized by relatively high rates of error as well as a marked reluctance to seek help. They also show the greatest educational gains from instruction with multiple rather than single representations. The behaviors that characterize this group illuminate the mechanism underlying the effectiveness of multiple representations and suggest strategies for tailoring instruction to individual students. Our methodology can be implemented in an on-line tutoring system to dynamically tailor individualized instruction. (shrink)

In the present context of aging populations, the question of how to support older workers who want to stay in employment longer is of particular importance, especially from a social justice perspective with regards to income. The challenges faced by organizations and governments are unprecedented. Interesting conclusions can be drawn from our research with regard to these challenges. First of all, the perception of retirement appears more or less unchanged over the years and remains very positive. Consequently, one of the (...) barriers to the employment of older workers may be the image of retirement itself, since it is still perceived as a gift or a right. Secondly, our results confirm that forcing people to stay longer in the labour market is a largely unpopular measure. Consequently, if public retirement plans offer limited income, governments and organizations should adopt a more voluntary approach to encourage older workers to stay in employment longer for a better income. Our results highlight the importance of the sector and type of job in the measures or incentives that could encourage older workers to stay in employment longer. Consequently, governments and organizations will probably have to adopt a contingent approach; i.e., all incentives do not necessarily fit all jobs or all sectors and social justice would require this be taken into account. We identified three sets of measures that could encourage older workers to stay in employment longer, and thus have access to better economic security: the reduction of working time, the flexibility of working time, and the individualization of retirement options and working time. The progressive reduction of their working time appears most interesting to our respondents. These measures appear to favour social justice in terms of income and right to employment at the end of active careers. (shrink)

Contemporary neo-liberal society is ruled by the market. Davies, Chen and Lentin and Titley show that its objectification and categorization founds a competitive notion of agency that disables subjective construction of self and intersubjective understanding of the world. As the market's rules and norms are set by white patriarchy, its competitive paradigm structurally disadvantages others. Art too is objectified and categorized by neo-liberal institutions, equally embedded in white patriarchal market structures and severely limiting democratic public access to a diverse artistic (...) field, argue hooks, Mercer and Piper. Yet, Piper's artwork shows, art holds emancipatory potential. Defined as transforming experience, its ambiguity provides a structure for constituting agentic subjectivity and intersubjective signification processes, defying objective/objectifying market workings. Photography's specific qualities allow Piper to democratize access to the paradigm she proposes. Her artistic choices may thus found the potential to publicly construct a notion of aesthetic agency as resistance to the neo-liberal market. (shrink)

Abstract:This symposium includes thirteen personal narratives from people who have received at least one organ transplant from a living or deceased donor. These narratives foster better understanding of the experiences of life-saving organ recipients and their families, including post-transplant difficulties experienced—sometimes requiring multiple transplants. This issue also includes three commentaries by Macey L. Levan, Heather Lannon, and Vidya Fleetwood, Roslyn B. Mannon & Krista L. Lentine. Dr. Levan is a living kidney donor and associate professor of surgery and population (...) health. She writes and teaches on organ transplant and has expertise and experience in governance at the federal level as a member of the board of directors for the U.S. Organ Procurement and Transplantation Network. Dr. Lannon is a social worker and transplant advocate. Her work and interest in the topic were inspired by her husband who needed a heart transplant. Dr. Fleetwood is a surgeon specializing in liver transplantation, pancreas transplantation, kidney transplantation, as well as living donor nephrectomy. Dr. Mannon is a nephrologist and professor of medicine, pathology and microbiology. Her work focuses on understanding and improving long-term kidney transplant outcomes for patients, donors, and caregivers. Dr. Lentine is a nephrologist specializing in treatment of adult patients with kidney disease. She is a researcher and co-chaired the international work group that developed guidelines for living donor kidney transplantation. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Editors’ NoteJames M. DuBois, Ana S. Iltis, and Heidi A. WalshFrom childhood, David Slakter had undergone tests and invasive procedures to monitor his nephritis. It was not a surprise when in 2015, doctors told him he needed a kidney transplant. The wife of a childhood friend was a close match and gave him one of her kidneys. Before his transplant, aerobic exercise was difficult; a few months after transplant, (...) Slakter could ride his bike, hike, and work out with a personal trainer. He no longer had to weigh food or gauge his potassium consumption, a concern for people with kidney failure. For Slakter, “life post-transplant has been a significant improvement.”Individuals or family members of those who have received an organ transplant from a living or deceased donor share their stories in this issue of Narrative Inquiry in Bioethics. The symposium is titled “Receiving the Gift of Life: Stories from Organ Transplant Recipients.” Organ transplantation can extend an individual’s life by decades. It can also greatly improve an individual’s quality of life, as was Slakter’s experience. At the same time, organ transplantation is expensive and stressful. Recipients can experience complications, including organ rejection, and there are few appealing alternatives.After her heart transplant, author Leilani R. Graham required four open-heart surgeries, ECMO, and an intra-aortic balloon pump. She experienced delirium, necrotizing pneumonia, and severe muscular atrophy that required her to re-learn how to walk. She struggled with weight gain, explosive mood swings, hair loss, and was terrified that her body would reject the new heart. For Graham, “[Transplant] was not the miracle [she] was hoping for.” Graham says she felt unprepared for and inadequately informed about what to expect after her transplant, which left her “battered, beaten, and bruised” with a 12-inch line from neck to navel and “bullet holes” up and down her torso from the chest tubes. When reflecting on her experience post-transplant, Graham says, “It wasn’t the physical trauma that hurt the most. It was that no one seemed surprised [by the aftereffects of transplant].” Seemingly no one, that is except Graham, who calls on transplant providers to “prioritize empathy.”The symposium editors are Jason T. Eberl and Tristan McIntosh. Three commentary articles, written by Macey Leigh Levan, Heather Lannon, and Vidya A. Fleetwood, Roslyn B. Mannon & Krista L. Lentine, offer important insights into the authors’ stories. The editors thank Mid-America Transplant, the UCSF Lung Transplant Program, Donor Connect, William L. Freeman, MD, MPH, MJIL, CIP, Janet Monk, and the individuals who gave anonymous donations to support the publication of this issue, an open-access VOICES edition of the symposium, and accompanying teaching guides.The research article in this issue, “‘A Shell of My Former Self’: Using Figurative Language to Promote Communication about Patient Suffering,” was written by Tyler Tate, Elizabeth Stein, and Robert A. Pearlman. The relief of suffering is a primary goal of medicine. However, the authors note that clinicians often miss or ignore suffering because they focus on the causes rather than the experience of suffering, or the subjective nature of suffering makes it difficult to discuss. The authors believe that “the key to communicating about suffering lies in finding [End Page vii] the right kind of words to describe the experience” and say that figurative language offers a promising approach. In their research, the authors performed qualitative analysis on 52 works of literature and identified 254 excerpts of figurative language with themes of non-physical or psychological suffering. The authors found 13 salient themes: brokenness, diminishment, disorientation, drowning, emptiness, imprisonment, battle, darkness, isolation, invisibility, lifelessness, punishment, and torture. The authors reiterate that developing a shared language of suffering could foster a therapeutic patient-clinician relationship and improve clinicians’ ability to recognize and address a patient’s experience of suffering.María Susana Ciruzzi wrote the first of two case studies included in this issue. “The Sword of King Solomon” addresses a tragic and difficult subject—how to navigate the situation posed by conjoined twins when “any decision will produce damage and suffering.” The case involves two infant male patients born at 37 weeks gestation as omphalo-ischiopagus conjoined twins...

Cet ouvrage rend hommage au Professeur Claude JOURNÈS, ancien Président de l'Université LUMIERE Lyon 2 et membre fondateur du mouvement Critique du droit. Les Mélanges offerts au Professeur Claude JOURNÈS ont retenu cette approche, utilisant le droit comme un outil de mise en perspective critique de l'ordre social et de l'ordre politique. Après un hommage au Doyen JOURNÉES (P. BLACHÈR) et l'évocation des ambitions et perspectives du mouvement critique Du droit (S. BASSET ou J. MICHEL), l'ouvrage se construit en deux (...) temps. La première partie, intitulée « Le droit critique de l'ordre social », regroupe des réflexions sur le pouvoir médical (F. DEMICHEL), sur les crimes coloniaux (A. MAHIOU), sur la dimension anthropologique du vocabulaire juridique (M.-C. HATTI) et sur le contrôle policier (M. SAOUDI), le tout ouvrant sur la possibilité d'un humanisme séculier (H. PUEL). La seconde partie, « Le droit critique de l'ordre politique », entend montrer comment le droit porte en lui une conception du pouvoir et de l'autorité. Les études explorent des pistes très diverses mêlant les finances publiques (J.-L. ALBERT), les renseignements (C. ARROUDJ), l'histoire du droit (J.-L. AUTIN, J.-C GENIN), l'histoire de la doctrine (H. GOURDON), les institutions politiques (P. BACOT, A.-S. MESCHERIAKOFF, R. CHARVIN), les institutions territoriales (J.-J. GLEUAL, H. OBERDORFF, R. PAVRE), la littérature (S. CAPORAL, G. HARE) ou les nouvelles technologies (G. PROTIÉRE). II ressort de l'ensemble que, loin d'être un simple outil technique, le droit est un puissant instrument de modélisation sociale et de justification du pouvoir. Inversant la logique dominante, la perspective critique du droit dévoile les limites d'une telle conception et rappelle que le droit, comme tous les construits sociaux, est le produit de luttes politiques et de rapports de force. En ce sens, à l'instar des valeurs défendues par le dédicataire de cet ouvrage, l'ordre critique du droit est un appel à contester les évidences, condition d'une conception plus ouverte et pluraliste de l'ordre juridique.
