Stroke survivors undergo a thorough cognitive diagnosis that often involves administration of multiple standardized tests. However, patient’s narrative discourse can provide clinicians with additional knowledge on patient’s subjective experience of illness, attitude toward current situation, and motivation for treatment. We evaluated the methods of analyzing thematic content and story types in relationship to cognitive impairment in stroke survivors with no aphasia. Cognitive impairment was evaluated in comparison to a group of 25 patients with orthopaedic injury not involving the brain. Our (...) findings primarily show that higher elaboration on own cognitive problems, physical ailments or coping strategies in LHD patients and cognitive problems, emotional issues and circumstances of illness onset in RHD patients is related to deficits in executive functions and retrieval of information from memory. Furthermore, RHD patients who use more chaos story type show lower executive functioning. However, these results did not survive the significance threshold of p < 0.05 after Bonferroni adjustment for multiple comparisons. In conclusion, this study provides preliminary evidence that stroke survivor’s narrative can constitute an additional source of clinically-relevant information regarding patient’s experience of illness and attitude toward recovery. This knowledge can aid clinicians and nurses in everyday interactions with the patients and support individualized strategy to treatment. Still, the current results need be confirmed with future studies in a larger cohort of stroke patients. (shrink)

A CHOICE Outstanding Academic Title 2012! Contemporary picturebooks open up spaces for philosophical dialogues between people of all ages. As works of art, picturebooks offer unique opportunities to explore ideas and to create meaning collaboratively. This book considers censorship of certain well-known picturebooks, challenging the assumptions on which this censorship is based. Through a lively exploration of children's responses to these same picturebooks the authors paint a way of working philosophically based on respectful listening and creative and authentic interactions, rather (...) than scripted lessons. This dialogical process challenges much current practice in education. The authors propose that a courageous and critical practice of listening is central to the facilitation of mutually educative dialogue. This book will be of interest to scholars and students of education studies, philosophy of education, literacy teaching and learning, children's literature, childhood and pedagogy. (shrink)

In this paper, we discuss the processes of racialisation on the example of biomedical research. We argue that applying the concept of racialisation in biomedical research can be much more precise, informative and suitable than currently used categories, such as race and ethnicity. For this purpose, we construct a model of the different processes affecting and co-shaping the racialisation of an individual, and consider these in relation to biomedical research, particularly to studies on hypertension. We finish with a discussion on (...) the potential application of our proposition to institutional guidelines on the use of racial categories in biomedical research. (shrink)

This fully revised second edition suggests ways in which you can introduce philosophical enquiry to your Personal, Social and Health Education and Citizenship teaching and across the curriculum.

It skilfully guides readers through this challenging and sometimes complex area bringing key philosophical ideas and questions to life in the context and practice of education. Considering the implications of educational trends and movements through a variety of philosophical lenses such as Marxism, feminism, ethics and democracy, the book explores enduring themes in philosophy of education. Features include: individual tasks and group activities to (...) promote discussion case studies notes boxes to highlight further reading; chapter overviews and summaries Drawing on readers' own experiences of education, the book reveals the connections between philosophical ideas and educational policy and practice. Part of the Foundations in Education Studies series, this timely textbook is essential reading for students coming to the study of philosophy of education for the first time. (shrink)

The author is in essential agreement with Tallis, that when we only deploy one mode of interpretation, ie the scientific mode, we lose the fundamental realities of human experience, including the experience of free will, on which, ironically, scientific practice depends. Tallis’s philosophical stance is compared to that of Owen Barfield and his work on free will is placed within the context of his other books. A sense of wonder is common to all of them.

Stimulated by late-1990s debate in the UK on quality, effectiveness and usefulness of educational research (reports by OFSTED, DFEE and NFER), this book shows ...

This article argues that the game presented in the third scene of the third act of Plautus’ Asinaria involves a horseplay rather than an assplay (Asin. 697–710). This is suggested by the young master's name, Argyrippus, and by a list of equine terms occurring in the text: uehere, inscendere, descendere, subdomari, tolutim, quadrupedo, aduorsom cliuom, in procliui.

The question of whether AI systems such as robots can or should be afforded moral agency or patiency is not one amenable either to discovery or simple reasoning, because we as societies constantly reconstruct our artefacts, including our ethical systems. Consequently, the place of AI systems in society is a matter of normative, not descriptive ethics. Here I start from a functionalist assumption, that ethics is the set of behaviour that maintains a society. This assumption allows me to exploit the (...) theoretical biology of sociality and autonomy to explain our moral intuitions. From this grounding I extend to consider possible ethics for maintaining either human- or of artefact-centred societies. I conclude that while constructing AI systems as either moral agents or patients is possible, neither is desirable. In particular, I argue that we are unlikely to construct a coherent ethics in which it it is ethical to afford AI moral subjectivity. We are therefore obliged not to build AI we are obliged to.

There is an abundance of enthusiasm and optimism about how governments at all levels can make use of big data, algorithms and artificial intelligence. There is also growing concern about the risks that come with these new systems. This article makes the case for greater government transparency and accountability about uses of big data through a Government of Canada qualitative research case study. Adapting a method from critical cartographers, I employ counter-mapping to map government big data practices and internal discussions (...) of risk and challenge. I do so by drawing on interviews and freedom of information requests. The analysis reveals that there are more concerns and risks than often publicly discussed and that there are significant areas of silence that need greater attention. The article underlines the need for our democratic systems to respond to our new datafied contexts by ensuring that our institutions make changes to better protect citizen rights, uphold democratic principles and ensure means for citizen intervention.

Conferring legal personhood on purely synthetic entities is a very real legal possibility, one under consideration presently by the European Union. We show here that such legislative action would be morally unnecessary and legally troublesome. While AI legal personhood may have some emotional or economic appeal, so do many superficially desirable hazards against which the law protects us. We review the utility and history of legal fictions of personhood, discussing salient precedents where such fictions resulted in abuse or incoherence. We (...) conclude that difficulties in holding “electronic persons” accountable when they violate the rights of others outweigh the highly precarious moral interests that AI legal personhood might protect.

A person who is liable to defensive harm has forfeited his rights against the imposition of the harm, and so is not wronged if that harm is imposed. A number of philosophers, most notably Jeff McMahan, argue for an instrumental account of liability, whereby a person is liable to defensive harm when he is either morally or culpably responsible for an unjust threat of harm to others, and when the imposition of defensive harm is necessary to avert the threatened unjust (...) harm. Others may favour a purely noninstrumental account of liability: one that looks only to the past behaviour of the potentially liable person. We argue that both views are vulnerable to serious objections. Instead we develop and defend a new view of liability to defensive harm: the pluralist account. The pluralist account states that liability to defensive harm has at least two bases. First, if an attacker is morally or culpably responsible for an unjust attack then he has forfeited what we call his agency right, and in doing so he has made himself partially liable to defensive harm. Whether the attacker is fully liable to defensive harm depends, however, on whether the imposition of defensive harm would infringe a different right held by the attacker: his humanitarian right. Humanitarian rights are rights to be provided with urgently needed resources or to be protected from serious harms when others can do so at reasonably low cost. We argue the pluralist account avoids the objections to which the instrumental and noninstrumental views are vulnerable, coheres with our intuitive reactions in a wide range of cases, and sheds new light on the way different rights combine to determine a person's liability to suffer harm.

Exercise-based rehabilitation forms a key part of the UK National Health Service patient-care pathway for cardiac rehabilitation (CR). Only around half of all eligible patients attend core CR, however, with social inequalities affecting participation. Few qualitative studies have explored in-depth the key factors influencing engagement with CR, specifically from a sociological theoretical, and ethnographic perspective. Utilising an ethnographic approach allowed us to get a sense of the embodied experiences of 10 participants attending or declining core CR, together with a further (...) seven family members/significant others. This provided in-depth appreciation of participants’ lifeworld contexts as key influences on CR participation. The article draws on these qualitative data and focuses on 1) participants’ initial thoughts about CR; and 2) navigating the field of CR, analysed via thematic analysis. We utilise a Bourdieusian theoretical perspective to theorise the findings, including salient socio-cultural factors influencing attendance/non-attendance and (non)adherence. The article findings highlight how perceptions of CR and the ability to navigate the field are strongly influenced by habitus and capital, and how personal biographies and socio-material conditions affect adherence to CR programmes. The study provides original insights into embodied experiences of exercise-based CR, and novel understandings of the reasons for drop-out/poor adherence, theorised from a Bourdieusian perspective.

In the recent philosophical literature, several counterexamples to the interpretative principle that symmetry-related models are physically equivalent have been suggested The Oxford handbook of philosophy of physics, Oxford University Press, Oxford, 2013, Noûs 52:946–981, 2018; Fletcher in Found Phys 50:228–249, 2020). Arguments based on these counterexamples can be understood as arguments from scientific practice of roughly the following form: because in scientific practice such-and-such symmetry-related models are treated as representing distinct physical situations, these models indeed represent distinct physical situations. In (...) this paper, a strategy for analysing arguments of this type is presented and applied to the examples that can be found in the literature. I argue that if we are exclusively interested in models understood as representing entire possible worlds, arguments from scientific practice should involve some additional assumptions to guarantee they are relevant for models understood in this way. However, none of the examples presented in the literature satisfy all these additional assumptions, which leads to the conclusion that arguments from scientific practice based on these examples do not undermine the interpretative principle that different symmetry-related models represent the same possible world.

Experience indicates that the questioning and democratic nature of the community of enquiry can be demanding and unsettling for teachers, present.

In the decades since the Science Wars of the 1990s, climate science has become a crucible for the negotiation of claims about reality and expertise. This negotiation, which has drawn explicitly on the ideas and techniques of science and technology studies, has taken place in genres of fiction as well as non-fiction, which intersect in surprising ways. In this case study, I focus on two interwoven strands of this history. One follows Michael Crichton’s best-selling 2004 novel, State of Fear and (...) its reception by neo-conservatives as a commentary on the mis-uses of facts to stoke fear about anthropogenic climate change. The other considers Naomi Oreskes and Erik M. Conway’s 2010 publishing success Merchants of Doubt as the inverse, a demonstration of the forms of disinformation that have been used to undermine scientific consensus around climate change. I show that both Crichton’s as well as Oreskes and Conway’s approaches were critiqued by academic STS even as their accounts constituted the most high-profile performances of its stakes and the politics of knowledge since the Science Wars. In highlighting the STS practices deployed by each, as well as how those practices were differently linked to accusations of fear-mongering and a perversion of the purity of STS, I demonstrate the need for a reflexive history of STS. Such an approach, I argue, can better consider the social life of STS ideas and practices amidst calls for more politically-engaged approaches to knowledge production. (shrink)

Since its advent in the 20th century, informed consent has become a cornerstone of ethical healthcare, and obtaining it a core obligation in medical contexts. In my dissertation, I aim to examine the theoretical underpinnings of informed consent and identify what values it is taken to protect. I will suggest that the fundamental motivation behind informed consent rests in something I’ll call bodily self-sovereignty, which I argue involves a coupling of two groups of values: autonomy and non-domination on the one (...) hand, and self-ownership and personal integrity on the other. I will then go on to consider two 'case studies' I take to shed light on what is at stake in securing informed consent - consent in psychiatrically ill populations, and consent to interventions that involve the modification of the genetic germline.

Unprecedented advances in medicine, genetic engineering, and demographic forecasting raise new questions that strain the categories and assumptions of traditional ethical theories. Heyd's approach resolves many paradoxes in intergenerational justice, while offering a major test case for the profound problems of the limits of ethics and the nature of value.

In this article, we analyse how researchers use the categories of race and ethnicity with reference to genetics and genomics. We show that there is still considerable conceptual “messiness” (despite the wide-ranging and popular debate on the subject) when it comes to the use of ethnoracial categories in genetics and genomics that among other things makes it difficult to properly compare and interpret research using ethnoracial categories, as well as draw conclusions from them. Finally, we briefly reconstruct some of the (...) biases of reductionism to which geneticists (as well as other researchers referring to genetic methods and explanations) are particularly exposed to, and we analyse the problem in the context of the biologization of ethnoracial categories. Our work constitutes a novel, in-depth contribution to the debate about reporting race and ethnicity in biomedical and health research. First, we reconstruct the theoretical background assumptions about racial ontology which researchers implicitly presume in their studies with the aid of a sample of recent papers published in medical journals about COVID-19. Secondly, we use the typology of the biases of reductionism to the problem of biologization of ethnoracial categories with reference to genetics and genomics. (shrink)

Each year thousands of individuals enrol in clinical trials as healthy volunteers to earn money. Some of them pursue research participation as a full-time or at least a part-time job. They call themselves professional or semiprofessional guinea pigs. The practice of paying healthy volunteers raises numerous ethical concerns. Different payment models have been discussed in literature. Dickert and Grady argue for a wage-payment model. This model gives research subjects a standardised hourly wage, and it is based on an assumption that (...) research participation is morally indistinguishable from other forms of unskilled labour. In this paper, I will challenge this assumption. I will argue that human guinea pigging has particular characteristics which taken together make it significantly different from other forms of labour. Participation in research is skill-independent. Healthy volunteers are valuable not because they are skilful persons, but because they are human bodies. The role of research volunteers is mainly passive. They are not asked to produce goods or deliver services. They are paid for enduring unpleasant, painful and risky interventions performed by investigators. Research volunteering involves inherent risks and uncertainties, and subjects have little or no control over their minimisation and materialisation. I conclude that participation in clinical research is a specific kind of activity. It is more like renting out one’s body to strangers, than working. Thus, research participation should not be treated on par with other forms of employment. (shrink)

Absolute velocities in Newtonian mechanics are commonly regarded as unmeasurable. Roberts (Br J Philos Sci 59(2):143–168, 2008) provides a justification for this thesis which appeals to the observational indistinguishability of boost-related models of Newtonian mechanics. Middleton and Murgueitio Ramírez (Australas J Philos, 2020) criticise his argumentation by pointing out that his analysis of the notion of measurement is too restrictive, and that, under a weaker analysis (based on counterfactuals), absolute velocities are measurable. Jacobs (Australas J Philos, 2020) opposes their view, (...) arguing that, on a properly formulated counterfactual-based account of measurement, absolute velocities are unmeasurable. However, in his argument, observational indistinguishability plays no role, even though, intuitively, it is very relevant for the issue of (un)measurability. This paper’s aim is to bring observational indistinguishability back to this discussion. I build upon the observation that there is an analogy between possible views on knowledge and justification on the one hand, and on measurement on the other. In particular, I explore the distinction between externalist and internalist approaches. Counterfactual-based accounts are all externalist, whereas the observational indistinguishability of boost-related models becomes relevant if we are interested in an internalist concept of measurement.

The article investigates the relations between Hausdorff and non-Hausdorff manifolds as objects of general relativity. We show that every non-Hausdorff manifold can be seen as a result of gluing together some Hausdorff manifolds. In the light of this result, we investigate a modal interpretation of a non-Hausdorff differential manifold, according to which it represents a bundle of alternative space-times, all of which are compatible with a given initial data set.

How leaders and managers respond to not knowing is highly relevant given the complex, ambiguous, and chaotic business environment of the twenty-first century. Drawing on the literature from a variety of disciplines, the paper explores the dominant, unfavorable conceptualization of not knowing. The authors present some potential ethical implications of a negative view of not knowing and suggest how organizations would benefit from identifying any unhelpful aspects of the culture that may encourage unethical, undesirable, and/or hasty actions in situations of (...) not knowing. The paper specifically illustrates how patience, courage, honesty, integrity, and humility are integral to negative capability in the contexts of not knowing. Finally, the paper calls for deeper inquiry into the role of virtue ethics in preparing managers and leaders for not knowing and urges organizations to embrace negative capability in not knowing rather than engaging in damaging delusion.

This study examines the conflation of terms such as “knowledge” and “understanding” in peer-reviewed literature, and tests the hypothesis that little current research clearly distinguishes between importantly distinct epistemic states. Two sets of data are presented from papers published in the journal Public Understanding of Science. In the first set, the digital text analysis tool, Voyant, is used to analyze all papers published in 2014 for the use of epistemic success terms. In the second set of data, all papers published (...) in Public Understanding of Science from 2010–2015 are systematically analyzed to identify instances in which epistemic states are empirically measured. The results indicate that epistemic success terms are inconsistently defined, and that measurement of understanding, in particular, is rarely achieved in public understanding of science studies. We suggest that more diligent attention to measuring understanding, as opposed to mere knowledge, will increase efficacy of scientific outreach and communication efforts. (shrink)

In this paper non-Hausdorff manifolds as potential basic objects of General Relativity are investigated. One can distinguish four stages of identifying an appropriate mathematical structure to describe physical systems: kinematic, dynamical, physical reasonability, and empirical. The thesis of this paper is that in the context of General Relativity, non-Hausdorff manifolds pass the first two stages, as they enable one to define the basic notions of differential geometry needed to pose the problem of the evolution-distribution of matter and are not in (...) conflict with the Einstein equations. With regard to the third stage, various potential conflicts with physical reasonability conditions are considered with a tentative conclusion that non-Hausdorff manifolds are more likely to pass this stage than is typically assumed. When dealing with some of these problems, the modal interpretation of non-Hausdorff manifolds is invoked, according to which they represent bundles of alternative possible spacetimes rather than single spacetimes.

Perez-Rodriguez and de la Fuente (2017) assume that although human races do not exist in a biological sense (“geneticists and evolutionary biologists generally agree that the division of humans into races/subspecies has no defensible scientific basis,” they exist only as “sociocultural constructions” and because of that maintain an illusory reality, for example, through “racialized” practices in medicine. Agreeing with the main postulates formulated in the article, we believe that the authors treat this problem in a superficial manner and have failed (...) to capture the current state of the field of knowledge in science and the humanities.

RD, a 32-year-old male, was admitted to the hospital with hypoxic COVID pneumonia–a potentially life-threatening condition characterized by dangerously low levels of oxygen in the body- during one of the pandemic’s surges. While RD’s age gave the clinical team hope for his prognosis, his ability to recover was complicated by his being unvaccinated and having multiple comorbidities, including diabetes and obesity. His condition worsened to the point that he required extracorporeal membrane oxygenation (ECMO), a machine that maintains the functioning of (...) a person’s heart and lungs. -/- Given its scarcity–only 264 of the over 6,000 hospitals in the United States offer ECMO, according to the Extracorporeal Life Support Organization–as well as its high cost and the inadequate supply of staff required to maintain it, ECMO primarily serves as a bridge to support critically ill patients until they can receive an organ transplant or implanted medical device. For RD, ECMO was started to support him until he could be evaluated for, and possibly receive, a bilateral lung transplant. Despite its intended use as a treatment of last resort, some patients can remain on ECMO for weeks or months. And some are awake, alert, and capable of medical decision-making. -/- RD was one such patient. However, the transplant evaluation committee ruled out RD’s candidacy for bilateral lung transplantation, based on his poor potential for recovery and a lack of family and friends to provide post-transplant support. This determination raised the prospect of continued ECMO treatment being a bridge to nowhere. But RD was comfortable on ECMO and wanted to remain in the ICU. The ICU intensivist contacted the ethics consult service with questions about whether continued ECMO support was medically and ethically inappropriate. (shrink)

The goals and tasks of neuroethics formulated by Farahany and Ramos (2020) link epistemological and methodological issues with ethical and social values. The authors refer simultaneously to the social significance and scientific reliability of the BRAIN Initiative. They openly argue that neuroethics should not only examine neuroscientific research in terms of “a rigorous, reproducible, and representative neuroscience research process” as well as “explore the unique nature of the study of the human brain through accurate and representative models of its function (...) and dysfunction”, but also its responsibilities or social consequences. In our commentary, we would like to concentrate on problem selection, which is shortly noticed by Farahany and Ramos, and by BRAIN Initiative’s Neuroethics Report itself. The document raises an important issue related to problem selection, which is strengthening or perpetuating existing prejudices and biases by choosing a research subject: “scientists are prompted to consider how the questions they choose to study in the laboratory might amplify existing biases.” This leads to several further problems: what constitutes bias?; how biases may be embedded in the selection of research programs?; is it possible to conduct completely unbiased research?; who should be a gatekeeper in the case of research that may amplify biases? We try to notice possible answers to these questions in the context of the research on differences (e.g., cognitive, medical, behavioral) between human populations. (shrink)

Preview: Shusterman, as a philosopher who draws from the work of John Dewey, has pragmatic expectations for art. For Dewey, communing with art was an intensification of experience, that is to say being in the world. For art is full of meaning, and it is in human nature to rush to search for meanings. Experience is only satisfactory if it enriches what is lived in it. Dewey’s message was one of the first voices to warn of the alienation of art. (...) According to it, its consumption should give people a chance for emotional and spiritual compassion. Richard Shusterman’s attitude toward art is similar: “As experience, art is obviously part of our lives, a particularly vivid form of our experienced reality, rather than a mere fictional imitation of it.” -/- Shusterman has developed his own concept of aesthetics, which he has called “somaesthetics” – the aesthetics of the soma. The Greek word soma here means a feeling, animated, purposeful body. Also, the term “aesthetics” is understood in a different way than its usual wider usage, according to which aesthetics is a theory of art and beauty. Shusterman refers to the old, original Greek word aisthetikos meaning sensory perception. The somaesthetic project’s goal is to combine theory with practice and consider the body in two ways: on the one hand, as a medium enabling cognition through perception, and on the other, as an external form of representation. That is why somaesthetics is interested in activities that expand and explore body awareness, such as meditation, yoga, and treatments that shape the appearance, including cosmetics and fashion. One of the main tasks of somaesthetics is to eliminate the dominant attitude toward the body in Western philosophy, which sees it as an obstacle to cognition. (shrink)

The use of the category of race in science remains controversial. During the last few years there has been a lively debate on this topic in the field of a relatively young neuroscience discipline called cultural neuroscience. The main focus of cultural neuroscience is on biocultural conditions of the development of different dimensions of human perceptive activity, both cognitive or emotional. These dimensions are analysed through the comparison of representatives of different social and ethnic groups. In my article, I present (...) arguments supporting these two hypotheses: the other-race effect understood as an individual, distinct effect does not exist. It is rather an exemplification of a much broader phenomenon which I call theunfamiliarity homogeneity effect. It includes not only problems with differentiation and recognition of faces of representatives of other ethnic groups, but also covers similar recognitional difficulties ; The race-based terminology and categories are used in cultural neuroscience research in a vague and inconsistent manner. Such an approach distorts the science both in empirically and conceptually significant respects. The unfamiliarity homogeneity effect is an example of such a situation: narrowing it to the other-race effect makes it difficult to analyse in a wider context crucial for its understanding. (shrink)

Reigning regulatory frameworks for biomedical research impose on researchers and research ethics committees an obligation to protect research participants from risks that are unnecessary, disproportionate to potential research benefits, and non-minimized. Where the research has no potential to produce results of direct benefit to the subjects and the subjects are unable to give consent, these requirements are strengthened by an additional condition, that risks should not exceed a certain minimal threshold. In this article, I address the question of whether there (...) should be limits of permissible risks in non-therapeutic research involving competent and healthy subjects. Some commentators argue that competent and informed individuals should have a right to participate even in extremely risky research and that research ethics committees should never reject studies because they are too dangerous. To use David Shaw's expression, competent volunteers should have ‘a right to participate in high-risk research’. I argue that this idea is ill-founded, as it does not take into account the social mission and complex collaborative nature of research practice as well as the inequity of power between researchers and subjects. Imposition of limits on permissible risks for healthy volunteers is justified by the need to protect research enterprise and the need to protect the weaker party, namely the subjects. Also, I suggest that the best way to set boundaries on research risks is to leave the judgment of risk acceptability to research ethics committees. (shrink)
