Somatic muscle formation is an unusual process as it requires the cells involved, the myoblasts, to relinquish their individual state and fuse with one another to form a syncitial muscle fiber. The potential use of myoblast fusion therapies to rebuild damaged muscles has generated continuing interest in elucidating the molecular basis of the fusion process. Yet, until recently, few of the molecular players involved in this process had been identified. Now, however, it has been possible to couple a detailed understanding (...) of the cellular basis of the fusion process with powerful classical and molecular genetic strategies in the Drosophila embryo. We review the cellular studies, and the recent genetic and biochemical analyses that uncovered interacting extracellular molecules present on fusing myoblasts and the intracellular effectors that facilitate fusion. With the conservation of proteins and protein functions across species, it is likely that these findings in Drosophila will benefit understanding of the myoblast fusion process in higher organisms.

Helen Steward argues that determinism is incompatible with agency itself--not only the special human variety of agency, but also powers which can be accorded to animal agents. She offers a distinctive, non-dualistic version of libertarianism, rooted in a conception of what biological forms of organisation might make possible in the way of freedom.

Helen Steward puts forward a radical critique of the foundations of contemporary philosophy of mind, arguing that it relies too heavily on insecure assumptions about the sorts of things there are in the mind--events, processes, and states. She offers a fresh investigation of these three categories, clarifying the distinctions between them, and argues that the category of state has been very widely and seriously misunderstood.

Recently several thought experiments have been developed (by John Carroll amongst others) which have been alleged to refute the Ramsey-Lewis view of laws of nature. The paper aims to show that two such thought experiments fail to establish that the Ramsey-Lewis view is false, since they presuppose a conception of laws of nature that is radically at odds with the Humean conception of laws embodied by the Ramsey-Lewis view. In particular, the thought experiments presuppose that laws of nature govern the (...) behavior of objects. The paper argues that the claim that laws govern should not be regarded as a conceptual truth, and shows how the governing conception of laws manifests itself in the thought experiments. Hence the thought experiments do not constitute genuine counter-examples to the Ramsey-Lewis view. since the Humean is free to reject the conception of laws which the thought experiments presuppose.

The Ethics of War and Peace is a lively introduction to one of the oldest but still most relevant ethical debates. Focusing on the philosophical questions surrounding the ethics of modern war, Helen Frowe presents contemporary just war theory in a stimulating and accessible way. This 2nd edition includes new material on weapons and technology, and humanitarian intervention, in addition to: theories of self-defence and national defence jus ad bellum, jus in bello and jus post bellum the moral status (...) of combatants the principle of non-combatant immunity and the nature of terrorism and the moral status of terrorists. Each chapter uses examples and concludes with a summary, discussion questions and suggestions for further reading to aid student engagement, learning and revision. The glossary has been expanded to cover the full range of relevant terminology. This is the ideal textbook for students of philosophy and politics approaching this important area for the first time.

The aim of this literature review was to compose a narrative review supported by a systematic approach to critically identify and examine concerns about accountability and the allocation of responsibility and legal liability as applied to the clinician and the technologist as applied the use of opaque AI-powered systems in clinical decision making. This review questions if it is permissible for a clinician to use an opaque AI system in clinical decision making and if a patient was harmed as a (...) result of using a clinician using an AIS’s suggestion, how would responsibility and legal liability be allocated? Literature was systematically searched, retrieved, and reviewed from nine databases, which also included items from three clinical professional regulators, as well as relevant grey literature from governmental and non-governmental organisations. This literature was subjected to inclusion/exclusion criteria; those items found relevant to this review underwent data extraction. This review found that there are multiple concerns about opacity, accountability, responsibility and liability when considering the stakeholders of technologists and clinicians in the creation and use of AIS in clinical decision making. Accountability is challenged when the AIS used is opaque, and allocation of responsibility is somewhat unclear. Legal analysis would help stakeholders to understand their obligations and prepare should an undesirable scenario of patient harm eventuate when AIS were used. (shrink)

The reductivist view of war holds that the moral rules of killing in war can be reduced to the moral rules that govern killing between individuals. Noam Zohar objects to reductivism on the grounds that the account of individual self-defence that best supports the rules of war will inadvertently sanction terrorist killings of non-combatants. I argue that even an extended account of self-defence—that is, an account that permits killing at least some innocent people to save one's own life—can support a (...) prohibition on terrorism, provided that it distinguishes between direct and indirect threats. What such an account cannot support is the blanket immunity of non-combatants to defensive killing. If a non-combatant is morally responsible for indirectly threatening in an unjust war, she can be liable to defensive killing. However, this gives us reason to revise our account of permissible killing in war, rather than to reject the reductivist account. (shrink)

Adil Ahmad Haque argues that civilians who contribute to unjust lethal threats in war, but who do not directly participate in the war, are not liable to defensive killing. His argument rests on two central claims: first, that the extent of a person’s liability to defensive harm in virtue of contributing to an unjust threat is limited to the cost that she is initially required to bear in order to avoid contributing, and, second, that civilians need not bear lethal costs (...) in order to avoid indirectly contributing to unjust lethal threats. I argue that Haque’s defence of each claim fails. (shrink)

This essay warns of eroding accountability in computerized societies. It argues that assumptions about computing and features of situations in which computers are produced create barriers to accountability. Drawing on philosophical analyses of moral blame and responsibility, four barriers are identified: 1) the problem of many hands, 2) the problem of bugs, 3) blaming the computer, and 4) software ownership without liability. The paper concludes with ideas on how to reverse this trend.

In an outline of a paper found amongst his philosophical papers and correspondence after his untimely death in 2001—“Nihil Obstat: An Analysis of Ability,” reproduced in this volume—David Lewis sketched a new compatibilist account of abilities, according to which someone is able to A if and only if there is no obstacle to their A-ing, where an obstacle is a ‘robust preventer’ of their A-ing. In this paper, we provide some background context for Lewis’s outline, a section-by-section commentary, and a (...) general discussion of the account’s main features. (shrink)

The modern view of causation can be traced back to the mechanistic science of Descartes, whose rejection of Aristotelian physics, with its concept of substantial forms, in favor of mechanical explanations was a turning-point in the history of philosophy. However the reasoning which led Descartes and other early moderns in this direction is not well understood. This book traces Descartes' groundbreaking theory of scientific explanation back to the mathematical demonstrations of Aristotelian mechanics and interprets these advances in light of the (...) available arguments for and against substantial forms. It also examines how Descartes' new theory led him to develop a metaphysical foundation for his science that could avoid skeptical objections. It will appeal to a wide range of readers interested in the philosophy and science of the early modern period. (shrink)

Artificially intelligent systems (AISs) are being created by software developing companies (SDCs) to influence clinical decision‐making. Historically, clinicians have led healthcare decision‐making, and the introduction of AISs makes SDCs novel actors in the clinical decision‐making space. Although these AISs are intended to influence a clinician's decision‐making, SDCs have been clear that clinicians are in fact the final decision‐makers in clinical care, and that AISs can only inform their decisions. As such, the default position is that clinicians should hold responsibility for (...) the outcomes of the use of AISs. This is not the case when an AIS has influenced a clinician's judgement and their subsequent decision. In this paper, we argue that this is an imbalanced and unjust position, and that careful thought needs to go into how personal moral responsibility for the use of AISs in clinical decision‐making should be attributed. This paper employs and examines the difference between prospective and retrospective responsibility and considers foreseeability as key in determining how personal moral responsibility can be justly attributed. This leads us to the view that moral responsibility for the outcomes of using AISs in healthcare ought to be shared by the clinical users and SDCs. (shrink)

Are animals agents? This question demands a prior answer to the question of what an agent is. The paper argues that we ought not to think of this as merely a matter of choosing from a range of alternative definitional stipulations. Evidence from developmental psychology is offered in support of the view that a basic concept of agency is a very early natural acquisition, which is established prior to the development of any full-blown propositional attitude concepts. Then it is argued (...) that whatever one makes of the developmental evidence, it is in any case arguable on other grounds that the concept of agency as we have it in adulthood remains perfectly comprehensible independently of any reference to the more sophisticated propositional attitudes. Any reluctance we might feel to ascribe such things as beliefs to non-human animals, therefore, need not stand in the way of the claim that they are agents, nevertheless. The paper attempts to characterise the core of this basic agency concept, and discusses, albeit briefly, the question how we ought to decide which animals are to be thought of as falling under it. It concludes with some speculations about the nature of the intellectual currents which have made the shape of this important concept so hard for us to discern. (shrink)

‘Natural kind essentialism’—here defined as the view that (i) the existence of natural kinds is a mind- and theory-independent matter, (ii) their essences are intrinsic, and (iii) they have a hierarchical structure—is commonly thought to be justified by appeal to Kripke–Putnam semantics, according to which propositions like ‘water is H20’ are necessary a posteriori. This chapter argues that the Kripke–Putnam semantics is in fact compatible with the denial of each of the three tenets of natural kind essentialism. The basic argument (...) is that, assuming the range of natural kinds goes beyond those kinds for which we have vernacular names, deference to scientific theories is required in fixing the reference of natural kind terms. That those theories describe mind- and theory-independent reality, and that they do not admit a non-hierarchical structure for the categories they deploy, are theses that are independent of anything derivable from Kripke–Putnam semantics itself.

Ethische Fragen der Pflegepraxis haben sich in den letzten Jahren zugespitzt. Sie sind häufig verbunden mit einer grundsätzlichen Sorge um eine kompetente und verantwortliche Pflege, die den Bedürfnissen von Patient*innen gerecht wird. Forschungen aus drei Jahrzehnten zeigen, dass strukturelle Beschränkungen, Konflikte mit Kolleg*innen, Patient*innen und Angehörigen sowie eine Managementorientierung und die Unsichtbarkeit der Pflegearbeit, Ursachen für die grundsätzlichen Sorgen sind. Sie führen zu moralischem Stress, fehlenden Beziehungen und einer Fragmentierung der Pflege. Teilweise reagieren Pflegende widerständig, indem sie beispielsweise die Regeln (...) beugen und eine passive „wait and see“ Position einnehmen. Einige Pflegende erheben ihre Stimme und suchen ein Klinisches Ethikkomitee auf. Klinische Ethikkomitees bieten eine Möglichkeit, die komplexen ethischen Fragen der Pflegepraxis zu thematisieren. Allerdings verweisen die Studien aus drei Dekaden auf einen Mangel der Thematisierung. Die Analyse der Ursachen lässt die Schlussfolgerung zu, demokratischen Lernprozessen Raum zu geben. (shrink)

Smart cities are now an established area of technological development and theoretical inquiry. Research on smart cities spans from investigations into its technological infrastructures and design scenarios, to critiques of its proposals for citizenship and sustainability. This article builds on this growing field, while at the same time accounting for expanded urban-sensing practices that take hold through citizen-sensing technologies. Detailing practice-based and participatory research that developed urban-sensing technologies for use in Southeast London, this article considers how the smart city as (...) a large-scale and monolithic version of urban systems breaks down in practice to reveal much different concretizations of sensors, cities, and people. By working through the specific instances where sensor technologies required inventive workarounds to be setup and continue to operate, as well as moments of breakdown and maintenance where sensors required fixes or adjustments, this article argues that urban sensing can produce much different encounters with urban technologies through lived experiences. Rather than propose a “grassroots” approach to the smart city, however, this article instead suggests that the smart city as a figure for urban development be contested and even surpassed by attending to workarounds that account more fully for digital urban practices and technologies as they are formed and situated within urban projects and community initiatives.

This article aims to shed light on what lies at the heart of skepticism towards counterfactual, alternative, or what-if history. On its face, counterfactual history gives historians and philosophers good reason to worry. First, because counterfactual pasts leave no traces, historians lack an important source of empirical warrant. Second, because rewriting historical events might unpredictably change the past, inferences about what might have happened seem only weakly supported by generalizations about what actually did happen. Third, counterfactual narratives appear especially vulnerable (...) to wishful thinking. Ultimately, through consideration of the epistemic values that regulate the construction of counterfactual narratives, I marshal arguments against these objections and defend the legitimacy of the project. Still, I hope to show that far from being a mere ‘parlor game’, counterfactual history raises deep and provocative questions about historians’ ability to know our past, only some of which I address here.

Recent figures have suggested that the composition of the student body is already changing in terms of mature and traditional student learner numbers--while 24% of full time students were over the age of 21 in 1980, this figure rose to 33% by 1996 . Using the Intrinsic Motivation towards Learning Questionnaire and the Rosenberg Global Self-Esteem Questionnaire , the current study documents the relationship between intrinsic motivation towards learning and self-esteem in traditional and mature students, in order to compare these (...) groups in their approach to learning. Results from sample size of 160 research participants indicated that self-esteem and intrinsic motivation towards learning were significantly associated. Mature women students had the highest intrinsic motivation scores, as well as the highest self-esteem scores in the sample. The findings are discussed in the light of previous research, which suggests that mature women students are vulnerable learners in higher education institutions and the study's conclusion draws attention to the current UK Government policy's commitment to expand student numbers.

In this article, Hannah Arendt's concept of action will be used to problematize current transformations of the health care sector and examine some responses by ethicists in light of those transformations. The sphere of human interaction that should typify health care work is identified as an action of unpredictable praxis in contrast to controllable procedures and techniques which increasingly take place in the health care sector.

There has been considerable recent debate about prostitution in Europe that reflects concerns about health, employment and human rights. Legal changes are being introduced in many countries. We focus on two examples in order to discuss the likely implications. A new law in The Netherlands is normalizing aspects of the sex industry through decriminalizing both workers and businesses. In Sweden, on the other hand, prostitution is considered to be a social problem, and a new law criminalizes the purchasers of sexual (...) services in an attempt to reduce demand. Both reforms appear to have had their desired effect at one level; in The Netherlands, health and safety regulations will be introduced as in any other job, and EU sex workers gain full social, legal and employment rights; in Sweden there was initially a tenfold decrease in the numbers of women working visibly on the streets, and some workers have left the industry. However, in both countries, the new legislation has also driven some sex work underground. Many sex workers are excluded by the Dutch system and move underground to become effectively invisible to the authorities. In Sweden sex workers and their clients also become less visible in order that the latter can avoid sanction. Social and economic changes, such as increased migration and the growing use of the Internet will also render the sex industry less visible both to state regulation and to health care workers. The major problems of prostitution for the workers remain exploitation, stigma, abuse and criminalization. These are not unique to the industry, and can only be tackled effectively by the self-organization of sex workers into unions and rights groups, along with full decriminalization. An alternative vision is promised through self-organization and anti-racist actions by sex workers in Germany; normalization and workers’ rights are tackled alongside training programmes for those seeking alternatives. Policy makers throughout Europe would do well to look at their experience and not simply at the clash of legal reforms. (shrink)

Care appears prima facie antithetical to punishment. Since the overlaps between care and punishment are greater than we paradigmatically expect, care ethics offers a more accurate account of prisons: recognising and critiquing both dehumanising carceral violence, and the necessity, presence, and inadequacies of penal care, as well as unlocking ways of thinking differently about structural change without losing sight of individual issues. After introducing care ethics and evidencing the presence of caring practices in present prisons, the article considers how we (...) punish, in terms of the amount, method, and manner. Treating people in punishment as moral equals is important for liberal deontological penal theories. Treatment as equals requires context. Context is intrinsic to care‐ethics praxis, which provides methods of and standards for accessing and applying this information. (shrink)

Infants are unable to make their own decisions or express their own wishes about medical procedures and treatments. They rely on surrogates to make decisions for them. Who should be the decision-maker when an infant’s biological parents are also minors? In this paper, we analyse a case in which the biological mother is a child. The central questions raised by the case are whether minor parents should make medical decisions on behalf of an infant, and if so, what are the (...) limits to this decision-making authority? In particular, can they refuse treatment that might be considered best for the infant? We examine different ethical arguments to underpin parental decision-making authority; we argue that provided that minor parents are capable of fulfilling their parental duties, they should have a right to make medical decisions for their infant. We then examine the ethical limits to minor parents’ decision-making authority for their children. We argue that the restricted authority that teenagers are granted to make medical decisions for themselves looks very similar to the restricted autonomy of all parents. That is, they are permitted to make choices, but not harmful choices. Like all parents, minor parents must not abuse or neglect their children and must also promote their welfare. They have a moral right to make medical decisions for their infants within the same ‘zone of parental discretion’ that applies to adult parents. We conclude that adult and minor parents should have comparable decision-making authority for their infants. (shrink)

How to embed reflexivity in public participation in techno-science and to open it up to the agency of publics are key concerns in current debates. There is a risk that engagements become limited to “laboratory experiments,” highly controlled and foreclosed by participation experts, particularly in upstream techno-sciences. In this paper, we propose a way to open up the “participation laboratory” by engaging localized, self-assembling publics in ways that respect and mobilize their ecologies of participation. Our innovative reflexive methodology introduced participatory (...) methods to public engagement with upstream techno-science, with the public contributing to both the content and format of the project. Reflecting on the project, we draw attention to the largely overlooked issue of temporalities of participation, and the co-production of futures and publics in participation methodologies. We argue that many public participation methodologies are underpinned by the open futures model, which imagines the future as a space of unrestrained creativity. We contrast that model with the lived futures model typical of localized publics, which respects latency of materials and processes but imposes limits on creativity. We argue that to continue being societally relevant and scientifically important, public participation methods should reconcile the open future of research with the lived futures of localized publics.

Individual choice and freedom are repeatedly invoked in contemporary policy debates, including those with a focus on risk behaviors such as smoking and health insurance coverage. The idea of making the right choice with regard to health and well-being has been fortified by the neoliberal discourse of self-reliance, personal autonomy, and responsibility. This neoliberal view, stemming from the conceptualization of freedom of philosopher John Stuart Mill justifying the freedom of the individual in opposition to unlimited state control, holds that success, (...) good health, and favorable educational outcomes are largely due to individual effort. Correspondingly, so too is failure, including failure of.. (shrink)

Mindfulness and compassion meditation are thought to cultivate prosocial behavior. However, the lack of diverse representation within both scientific and participant populations in contemplative neuroscience may limit generalizability and translation of prior findings. To address these issues, we propose a research framework calledIntersectional Neurosciencewhich adapts research procedures to be more inclusive of under-represented groups. Intersectional Neuroscience builds inclusive processes into research design using two main approaches: 1) community engagement with diverse participants, and 2) individualized multivariate neuroscience methods to accommodate neural (...) diversity. We tested the feasibility of this framework in partnership with a diverse U.S. meditation center (East Bay Meditation Center, Oakland, CA). Using focus group and community feedback, we adapted functional magnetic resonance imaging (fMRI) screening and recruitment procedures to be inclusive of participants from various under-represented groups, including racial and ethnic minorities, gender and sexual minorities, people with disabilities, neuropsychiatric disorders, and/or lower income. Using person-centered screening and study materials, we recruited and scanned 15 diverse meditators (80% racial/ethnic minorities, 53% gender and sexual minorities). The participants completed the EMBODY task – which applies individualized machine learning algorithms to fMRI data – to identify mental states during breath-focused meditation, a basic skill that stabilizes attention to support interoception and compassion. All 15 meditators’ unique brain patterns were recognized by machine learning algorithms significantly above chance levels. These individualized brain patterns were used to decode the internal focus of attention throughout a 10-min breath-focused meditation period, specific to each meditator. These data were used to compile individual-level attention profiles during meditation, such as the percentage time attending to the breath, mind wandering, or engaging in self-referential processing. This study provides feasibility of employing an intersectional neuroscience approach to include diverse participants and develop individualized neural metrics of meditation practice. Through inclusion of more under-represented groups while developing reciprocal partnerships, intersectional neuroscience turns the research process into an embodied form of social action. (shrink)

Mix & Stir', this book's aim is an endeavour to understand art as being a panhuman phenomenon of all times and cultures; to steer away from the persistent Eurocentric/Western-centric viewpoint towards a transcultural and transnational interconnected model of exchange and processes of interculturalization. Mix & Stir wants to expand this landscape by bringing to the fore new, recalcitrant, queer, idiosyncratic practices and discourses, theories and topics, methods and concerns that open up ways to approach art from a global perspective. Analogous (...) to a cookery book filled with recipes and instruction, Mix & Stir explores new outlooks on contemporary art from global perspectives. It intends to encourage studying art beyond national constraints, cultural dominances, and hierarchies: a voyage similar to that of culinary discovery. The book brings a variety of tastes and flavours to the table, and breaks new ground by allowing innovative, contrary, queer, idiosyncratic practices and discourses, theories and topics, methods, and concerns to access art in its global dimensions. Researchers, curators and artists with a special interest in this topical issue were invited to present, develop, outline, and contemplate compelling frames of reference, both theoretical and artistic, in order to arrive at a true 'world art studies'. Their contributions are structured in seven thematic fields: Undecidability and Spectatorship, Collectives, Circulations, Exhibitions, Artists at Work, Postcolonial Perspectives, and Deep Art History. The reader is invited to explore the vast supply of dishes, to taste and test the aromas and to feast. (shrink)

This paper argues that the position on free will which is defended in ‘Freedom: An Impossible Reality’ is not, as Tallis claims, a compatibilist view, but actually a version of libertarianism. While endorsing many aspects of that libertarian view itself, the paper raises questions about how one of the central arguments for Tallis’s view is supposed to work, and queries whether it really follows from the fact that we need to stand apart from nature in a certain sense, in order (...) to develop the kind of abstract knowledge that is constituted by the body of scientific law, that our own actions are not mere manifestations of what Tallis calls the ‘habits of nature’. It is also suggested that while a strong case can be made for many varieties of human exceptionalism, Tallis’s view of animal behaviour may be too simple and that there are examples of animal agency which cannot be explained merely by the associative learning which appears to be the highest grade of animal cognition that Tallis countenances.

The aim of this article is to analyse environmental reporting in the Australian broadsheet newspaper The Sydney Morning Herald. The focus is on a particular kind of new, multisemiotic news story genre that appears regularly in this newspaper, and that makes use of word-image play. Using a social semiotic framework and employing Appraisal theory, we analyse a corpus of 40 stories in terms of evaluative meanings in heading, image and caption, and interpret the significance of our findings in terms of (...) both Critical Discourse Analysis and Positive Discourse Analysis. In particular, we question whether the playing with environmental stories in the news, and the resulting clash between the humorousness of the play and the seriousness of the reported environmental event, is good or bad practice. With its multisemiotic focus, this article aims to make a significant and innovative contribution to the emerging field of ecolinguistics, and the development of Appraisal theory. (shrink)

We raise the new possibility that people diagnosed with developmental dyslexia (DD) are specialized in explorative cognitive search, and rather than having a neurocognitive disorder, play an essential role in human adaptation. Most DD research has studied educational difficulties, with theories framing differences in neurocognitive processes as deficits. However, people with DD are also often proposed to have certain strengths – particularly in realms like discovery, invention, and creativity – that deficit-centered theories cannot explain. We investigate whether these strengths reflect (...) an underlying explorative specialization. We re-examine experimental studies in psychology and neuroscience using the framework ofcognitive search, whereby many psychological processes involve a trade-off between exploration and exploitation. We report evidence of an explorative bias in DD-associated cognitive strategies. High DD prevalence and an attendant explorative bias across multiple areas of cognition suggest the existence of explorative specialization. An evolutionary perspective explains the combination of findings and challenges the view that individuals with DD have a disorder. In cooperating groups, individual specialization is favored when features that confer fitness benefits are functionally incompatible. Evidence for search specialization suggests that, as with some other social organisms, humans mediate the exploration–exploitation trade-off by specializing in complementary strategies. The existence of a system of collective cognitive search that emerges through collaboration would help to explain our species’ exceptional adaptiveness. It also aligns with evidence for substantial variability during our evolutionary history and the notion that humans are adapted not to a particular habitat but to variability itself. Specialization creates interdependence and necessitates balancing complementary strategies. Reframing DD therefore underscores the urgency of changing certain cultural practices to ensure we do not inhibit adaptation. Key improvements would remove cultural barriers to exploration and nurture explorative learning in education, academia, and the workplace, as well as emphasize collaboration over competition. Specialization in complementary search abilities represents a meta-adaptation; through collaboration, this likely enables human groups (as a species and as cultural systems) to successfully adapt. Cultural change to support this system of collaborative search may therefore be essential in confronting the challenges humanity now faces. (shrink)
