BackgroundThe triangle completion test has been used to assess egocentric wayfinding for decades, yet there is little information on its reliability. We developed a virtual reality based test and investigated whether either test of spatial navigation was reliable.ObjectiveTo examine test-retest reliability of the real-world and VR triangle completion tests. A secondary objective was to examine the usability of the VR based test.Materials and methodsThirty healthy adults aged 18–45 years were recruited to this block randomized study. Participants completed two sessions of (...) triangle completion tests in the real-world and VR on the same day with a break between sessions.ResultsIn both test versions distance from the endpoint and angle of deviation showed poor test-retest reliability. Distance traveled had moderate reliability in both the real-world and VR tests. The VR triangle test showed poor correlation with the real-world test.ConclusionThe triangle completion test has poor test-retest reliability and demonstrates poor concurrent validity between the real-world and VR. Nevertheless, it was feasible to translate a real-world test of spatial navigation into VR. VR provides opportunities for development of clinically relevant spatial navigation tests in the future.

This paper argues that individuals in many high-income countries typically have moral reasons to limit their beef consumption and consume plant-based protein instead, given the negative effects of beef production and consumption. Beef production is a significant source of agricultural greenhouse gas emissions and other environmental impacts, high levels of beef consumption are associated with health risks, and some cattle production systems raise animal welfare concerns. These negative effects matter, from a variety of moral perspectives, and give us collective moral (...) reasons to reduce beef production and consumption. But, as some ethicists have argued, we cannot draw a straight line from the ethics of production to the ethics of consumption: even if a production system is morally impermissible, this does not mean that any given individual has moral reasons to stop consuming the products of that system, given how miniscule one individual’s contributions are. This paper considers how to connect those dots. We consider three distinct lines of argument in support of the conclusion that individuals have moral reasons to limit their beef consumption and shift to plant-based protein, and we consider objections to each argument. This argument applies to individuals in high beef-consuming and high greenhouse gas-emitting high-income countries, though we make this argument with a specific focus on the United States. (shrink)

This book provides an analysis of the debate surrounding cultural diversity, and attempts to reconcile the seemingly opposing views of "ethical imperialism," the belief that each individual is entitled to fundamental human rights, and cultural relativism, the belief that ethics must be relative to particular cultures and societies. The author examines the role of cultural tradition, often used as a defense against critical ethical judgments. Key issues in health and medicine are explored in the context of cultural diversity: the physician-patient (...) relationship, disclosing a diagnosis of a fatal illness, informed consent, brain death and organ transplantation, rituals surrounding birth and death, female genital mutilation, sex selection of offspring, fertility regulation, and biomedical research involving human subjects. Among the conclusions the author reaches are that ethical universals exist, but must not be confused with ethical absolutes. The existence of ethical universals is compatible with a variety of culturally relative interpretations, and some rights related to medicine and health care should be considered human rights. Illustrative examples are drawn from the author's experiences serving on international ethical review committees and her travels to countries in Africa, Asia, and Latin America, where she conducted educational workshops and carried out out her own research.

Groff defends 'realism about causality' through close discussions of Kant, Hilary Putnam, Brian Ellis and Charles Taylor, among others. In so doing she affirms critical realism, but with several important qualifications. In particular, she rejects the theory of truth advanced by Roy Bhaskar. She also attempts to both clarify and correct earlier critical realist attempts to apply realism about causality to the social sciences. By connecting issues in metaphysics and philosophy of science to the problem of relativism, Groff bridges the (...) gap between the philosophical literature and broader debates surrounding socio-political theory and poststructuralist thought. This unique approach will make the book of interest to philosophers and socio-political theorists alike. (shrink)

Ontology. Revisited. Groff's argument cuts against a familiar anti-metaphysical grain. Social and political philosophy, she maintains, is not as metaphysically neutral as it may seem. Even the most deontological of theories connects up with a ...

Summary Popular science journalism flourished in the 1860s in England, with many new journals being projected. The time was ripe, Victorian men of science believed, for an ?organ of science? to provide a means of communication between specialties, and between men of science and the public. New formats were tried as new purposes emerged. Popular science journalism became less recreational and educational. Editorial commentary and reviewing the progress of science became more important. The analysis here emphasizes those aspects of popular (...) science which have been identified by Frank Turner as ?public science? and by Thomas Gieryn as ?boundary-work?. The religious, intellectual, and utilitarian values claimed for science by editors and contributors in their tasks of persuading the public to support science and of distinguishing science from what they often called ?applied science? are discussed. These values are shown to vary among editors and, for the editors examined here, Shirley Hibberd, Henry Slack, James Samuelson, William Crookes, and Henry Lawson, to differ significantly from those of T. H. Huxley, John Tyndall, and Norman Lockyer, on whom much study of the popularization of science in the 1860s has focused. (shrink)

Healthcare professionals are currently working under extreme pressure as they respond to the pandemic outbreak of COVID-19. At the time of writing, there is currently no effective vaccine or anti-viral treatment. The pandemic is fast-moving, relatively unpredictable and of uncertain duration. In many countries, it is placing an enormous stress on healthcare resources and providing care to existing standards is proving difficult. Unfortunately, in some countries, health services have been overwhelmed. The impact of the pandemic on resource-poor countries is of (...) particular concern. This extraordinary situation is raising, or has the potential to raise, many ethical challenges for doctors delivering care to patients. It is possible, for example, that there may be points in this pandemic where decisions need to be made about who should have access to finite specialised intensive care beds, drugs and equipment. This has happened in some countries and, despite efforts by the UK Government to reduce demand and increase supply, it is still possible that this could happen in the UK. Some hospital trusts in the UK are already reporting concerningly low supplies of oxygen and vital medicines such as propofol and alfentanil.1 In these circumstances, where not everyone can be treated, difficult ethical decisions will have to made. For example, can some patients be prioritised over others? How should a doctor decide on which patients to treat? Can treatment be withdrawn from patients who are currently being treated, but are not responding, in order to offer treatment to those who may have a better chance of benefiting? The UK is also reporting concerningly low supplies of vital personal protective equipment for frontline workers, raising the question - what are a doctor’s obligations to treat patients, in circumstances that present a high ….

There is considerable confusion regarding the ethical appropriateness of using incentives in research with human subjects. Previous work on determining whether incentives are unethical considers them as a form of undue influence or coercive offer. We understand the ethical issue of undue influence as an issue, not of coercion, but of corruption of judgment. By doing so we find that, for the most part, the use of incentives to recruit and retain research subjects is innocuous. But there are some instances (...) where it is not. Specifically, incentives become problematic when conjoined with the following factors, singly or in combination with one another: where the subject is in a dependency relationship with the researcher, where the risks are particularly high, where the research is degrading, where the participant will only consent if the incentive is relatively large because the participant's aversion to the study is strong, and where the aversion is a principled one. The factors we have identified and the kinds of judgments they require differ substantially from those considered crucial in most previous discussions of the ethics of employing incentives in research with human subjects.

A prominent feature of late nineteenth-century psychology was its intense preoccupation with precision. Precision was at once an ideal and an argument: the quest for precision helped psychology to establish its status as a mature science, sharing a characteristic concern with the natural sciences. We will analyse how psychologists set out to produce precision in 'mental chronometry', the measurement of the duration of psychological processes. In his Leipzig laboratory, Wundt inaugurated an elaborate research programme on mental chronometry. We will look (...) at the problem of calibration of experimental apparatus and will describe the intricate material, literary, and social technologies involved in the manufacture of precision. First, we shall discuss some of the technical problems involved in the measurement of ever shorter time-spans. Next, the Cattell-Berger experiments will help us to argue against the received view that all the precision went into the hardware, and practically none into the social organization of experimentation. Experimenters made deliberate efforts to bring themselves and their subjects under a regime of control and calibration similar to that which reigned over the experimental machinery. In Leipzig psychology, the particular blend of material and social technology resulted in a specific object of study: the generalized mind. We will then show that the distribution of precision in experimental psychology outside Leipzig demanded a concerted effort of instruments, texts, and people. It will appear that the forceful attempts to produce precision and uniformity had some rather paradoxical consequences. (shrink)

Increasingly in the modern world, incentives are becoming the tool we reach for when we wish to bring about change. In government, in education, in health care, between and within institutions of all sorts, incentives are offered to steer people's choices in certain directions. But despite the increasing interest in ethics and economics, the ethics of the use of incentives has raised very little concern. From a certain point of view, this is not surprising. When incentives are viewed from the (...) perspective of market economics, they appear to be entirely unproblematic. An incentive is an offer of something of value, sometimes with a cash equivalent and sometimes not, meant to influence the payoff structure of a utility calculation so as to alter a person's course of action. In other words, the person offering the incentive means to make one choice more attractive to the person responding to the incentive than any other alternative. Both parties stand to gain from the resulting choice. In effect, it is a form of trade, and as such, it meets certain ethical requirements by definition. A trade involves voluntary action by all parties concerned to bring about a result that is beneficial to all parties concerned. If these conditions were not met, the trade would simply not occur. And as inducements in a voluntary transaction, incentives certainly have the moral high ground over coercion as an alternative. (shrink)

Connected Lives examines the account of human nature that is implicit in an ethics of care, a picture of human lives that emphasizes interdependency, embodiment, and social connectedness. The book makes important connections to the picture of human life found in theorists of love such as St. Augustine and Emmanuel Levinas, and shows that when care theory is articulated clearly, it provides resources for thinking through some of the difficult moral issues we face in the contemporary world, issues such as (...) assisted reproduction and the new genetic technologies.

Most of Christine Swanton’s quotations from and references to Nietzsche are drawn The Genealogy of Morals, Thus Spoke Zarathustra, and Beyond Good and Evil. I suggest that Human, All too Human and Daybreak, two of Nietzsche’s most neglected works, provide rich resources for Swanton’s interpretation of Nietzsche’s view of self-love and its defining role in genuinely ethical action. Self-love assumes a central place in these writings, as do its cognate concepts of egoism and vanity. I outline some of the reasons (...) why these two middle period writings recommend themselves powerfully for Swanton’s philosophical purposes. I examine to what extent passages on self-love from these neglected works nourish, but also to what extent they challenge or upset, the central place accorded to self-love in Swanton’s recalibration of virtue ethics.

Citizenship and its education is again gaining importance in many countries. This paper uses England as its primary example to develop a Habermasian perspective on this issue. The statutory requirements for citizenship education in England imply that significant attention be given to the moral and social development of the learner over time, to the active engagement of the learner in community and to the knowledge skills and understanding necessary for political action. This paper sets out a theoretical framework that offers (...) a perspective on learning suitable for these far-reaching aims. We argue that schools need to shift from the currently dominant discourse of accountability to incorporate a discourse of care in order to make room for an effective and appropriate pedagogy for citizenship. Habermas’s social theory gives us a theoretical framework that properly locates schools within the lifeworld as part of civil society. Schools should therefore attend to hermeneutical and emancipatory concerns, not only to strategic interests. We put these in the context of Habermas’s social theory to paint an alternative vision learning for citizenship education which is based in developing the dispositions, values and attitudes necessary for lifelong learning with a view to developing ongoing communicative action.

Feminist philosophers of science have produced an exciting array of works in the last several years, from critiques of androcentrism in traditional science to theories about what might constitute feminist science. I suggest here another possibility: that gynocentric science has existed all along, then the task of identifying a feminist alternative to androcentric science should be a suitable candidate for empirical investigation. Such empirical investigation could provide a solid ground for further theorizing about feminist science at a time when that (...) solid ground is looking rather necessary. (shrink)

A synthesis of rights and participatory approaches to citizenship, linked through the notion of human agency, is proposed as the basis for a feminist theory of citizenship. Such a theory has to address citizenship's exclusionary power in relation to both nation-state ‘outsiders’ and ‘insiders’. With regard to the former, the article argues that a feminist theory and politics of citizenship must embrace an internationalist agenda. With regard to the latter, it offers the concept of a ‘differentiated universalism’ as an attempt (...) to reconcile the universalism which lies at the heart of citizenship with the demands of a politics of difference. Embracing also the reconstruction of the public-private dichotomy, citizenship, reconceptualized in this way, can, it is argued, provide us with an important theoretical and political tool. (shrink)

Hume’s famous argument against the credibility of testimony about miracles invokes two premises: 1) The reliability of the witness (the extent to which he is informed and truthful) must be compared with the intrinsic probability of the miracle. 2) The initial probability of a miracle is always small enough to outweigh the improbability that the testimony is false (even when the witness is assumed to be reliable). I defend the first premise of the argument, showing that Hume’s argument can be (...) applied to purported observations of miracles, as well. I then show that Hume failed to provide an adequate support for his second premise. A more cogent defence can be provided for a weaker premise. The resultant argument has, consequently, a less sweeping conclusion than Hume’s. (shrink)

Lewis’s view of the way conventions are passed on may have some especially interesting consequences for the study of language. I’ll start by briefly discussing agreements and disagreements that I have with Lewis’s general views on conventions and then turn to how linguistic conventions spread. I’ll compare views of main stream generative linguistics, in particular, Chomsky’s views on how syntactic forms are passed on, with the sort of view of language acquisition and language change advocated by usage-based or construction grammars, (...) which seem to fit better with Lewis’s ideas. Then I will illustrate the interest of Lewis’s perspective on the dissemination of conventions with a variety of linguistic examples. (shrink)

On Reading Signs; Some Differences between Us and The Others If there are certain kinds of signs that an animal cannot learn to interpret, that might be for any of a number of reasons. It might be, first, because the animal cannot discriminate the signs from one another. For example, although human babies learn to discriminate human speech sounds according to the phonological structures of their native languages very easily, it may be that few if any other animals are capable (...) of fully grasping the phonological structures of human languages. If an animal cannot learn to interpret certain signs it might be, second, because the decoding is too difficult for it. It could be, for example, that some animals are incapable of decoding signs that exhibit syntactic embedding, or signs that are spread out over time as opposed to over space. Problems of these various kinds might be solved by using another sign system, say, gestures rather than noises, or visual icons laid out in spatial order, or by separating out embedded propositions and presenting each separately. But a more interesting reason that an animal might be incapable of understanding a sign would be that it lacked mental representations of the necessary kind. It might be incapable of representing mentally what the sign conveys. When discussing what signs animals can understand or.. (shrink)

It has been suggested that a substitutional semantics for quantification theory lends itself to nominalistic aims. I should like in this paper to explore that claim.

I present a puzzle which seems simple, but is found to have interesting implications for confirmation. Its dissolution also helps us to throw light on the relationship between first- and second-order probabilities construed as rational degrees of belief.

This collection of Marcus's non-technical essays include her earlier ground-breaking axiomatizations of quantified modal logic, and explore such topics as the necessity of identity, the directly referential role of proper names as "tags", the interplay of possibility and existence, and others viewed as iconoclastic when Marcus first addressed them, but now long incorporated into current discussion.

Physical inactivity and coronavirus disease 2019 signify two pandemics with negative physical, mental, and economic consequences. Younger and older people have not reached the recommended physical activity level for years. Societal restrictions due to COVID-19 additionally reduce opportunities for physical activity, and they increase social isolation. Here, we outline how playing exergames with others at home could foster physical and mental health and promote communication and discussions on exergaming. Accordingly, we highlight the educational and social benefits of exergaming at home (...) and delineate the concept of Educational and Social Exergaming. We outline specific benefits and pitfalls of exergaming regarding its physical and nonphysical effects, including educational values of discussing exergaming experiences and related topics. Moreover, we discuss the relevance of practical guidelines for educational and social exergaming at home as well as prospects for future research. Overall, educational and social exergaming could alleviate several detrimental effects of both pandemics on the health and well-being of people of all ages. (shrink)

The biggest contemporary challenge to democratic legitimacy gravitates around the crisis of democratic representation.

Notions of recognition and difference do not inform the mainstream debate about welfare reform, which is, instead, dominated by a dichotomous discourse of active modernization vs passive ‘welfare dependency’. The article challenges this dichotomy within the context of New Labour’s welfare reform agenda in the UK. It argues, first, that welfare reform should treat improvements in social security benefits not as promoting ‘passive’ welfare but as complementary to labour market activation policies. Second, it redefines active welfare to incorporate notions of (...) active citizenship, which construct welfare subjects as actors in the political process of welfare policy-making and delivery. As a framework for this position, the article discusses three ‘R’s of welfare reform, risk protection, redistribution and recognition, together with the further two ‘R’s of rights and responsibilities. It concludes by emphasizing the importance of a rights agenda both to tackling poverty and exclusion and to recognition politics. (shrink)

In this commentary, we raise two issues. First, we argue that in any species, the comparative study of metacognitive abilities must be approached from a developmental perspective and not solely from the adult end state. This makes it possible to explore the trajectories by which different species reach their phenotypic outcome and whether different cognitive systems interact over developmental time. Second, using our research comparing different genetic disorders in humans, we challenge the authors' claim that it is unparsimonious to interpret (...) the same performance in humans and animals in qualitatively different ways, because even the same overt behaviour in different groups of humans can be sustained by different underlying cognitive processes.

We examine how UK listed companies set executive pay, reviewing the implications of following best practice in corporate governance and examining how this can conflict with what shareholders and other stakeholders might perceive as good behaviour. We do this by considering current governance regulation in the light of interviews with protagonists in the debate, setting out the dilemmas faced by remuneration-setters, and showing how the processes they follow can lead to ethical conflicts. Current 'best' practice governing executive pay includes the (...) use of market benchmarks to determine salary and bonus levels, significant levels of performance-related pay, the desire for executives to hold equity in their companies, the disclosure of total shareholder return compared to an index, and a perceived need for conformity, in order to grant legitimacy to policies. Whilst each of these may in some circumstances lead to good practice, each has the potential to cause dysfunctional behaviour in executives. Overall, we conclude that although best practice might drive good executive behaviour that coincides with the company's and key stakeholders' objectives, there are many reasons why it should not.
