Jason Stanley has proposed that we can account for the effects of extralinguistic context on truth-conditional content whilst remaining loyal to a compositional semantics for natural language. This is possible, he argues, because there are covert variables present in the logical forms of certain sentences whose values are fixed relative to contexts, but which do not register in the overt structure of those sentences. In the present article I assess the plausibility of positing such variables in logical form, focusing particularly (...) on the examples Stanley provides in order to corroborate their presence. I argue that these examples are apt for an alternative treatment than that offered by Stanley—one which does not make recourse to covert variables, and is hence more credible. I end by spelling out some consequences of this argument for Stanley’s proposal. (shrink)

Successful prototype marine chronometers, developed by Harrison and others in the eighteenth century, stimulated a sector of the British watchmaking industry to supply Admiralty and commercial demand for this instrument. Chronometers, like other British-made timepieces, were constructed by an elaborate pre-industrial method of production. The instrument's static technology and extreme durability meant replacement demand was minimal, and new demand was low relative to existing stock and the industry's capacity. The First World War created a final surge of demand that left (...) supplies far in excess of peacetime needs; and a new technology—radio transmissions of time signals—offered an alternative method of determining Greenwich time, and thus longitude, at sea.

ABSTRACTThere is a growing body of literature describing conceptual frameworks for working with participatory visual methods. Through a global health lens, this paper examines some key themes within these frameworks. We reflect on our experiences of working with with an array of PVM to engage community members in Vietnam, Kenya, the Philippines and South Africa in biomedical research and public health. The participants that we have engaged in these processes live in under-resourced areas with high prevalence of communicable and non-communicable (...) diseases. Our paper describes some of the challenges that we have encountered while using PVM to foster knowledge exchange, build relationships and facilitate change among individuals and families, community members, health workers, biomedical scientists and researchers. We consider multiple ethical situations that have arisen through our work and discuss the ways in which we have navigated and negotiated them. We offer our reflections and learning from facil...

International research guidance has shifted towards an increasingly proactive inclusion of children and adolescents in health research in recognition of the need for more evidence-based treatment. Strong calls have been made for the active involvement of children and adolescents in developing research proposals and policies, including in decision-making about research participation. Much evidence and debate on this topic has focused on high-income settings, while the greatest health burdens and research gaps occur in low-middle income countries, highlighting the need to take (...) account of voices from more diverse contexts. Between January and March 2014, 56 community representatives and secondary school students were involved in eight group discussions to explore views on the acceptability of involving children and adolescents in research, and how these groups should be involved in decision-making about their own participation. Discussions were voice-recorded and transcriptions analyzed using Framework Analysis, combining deductive and inductive approaches. Across these discussions, the idea of involving children and adolescents in decision-making about research participation was strongly supported given similar levels of responsibility carried in everyday life; existing capacity that should be recognized; the opportunity for learning involved; varying levels of parental control; and generational shifts towards greater understanding of science for adolescents than their parents. Joint decision-making processes were supported for older children and adolescents, with parental control influenced by perceptions of the risks involved in participation. Moves towards more active involvement of children and adolescents in planning studies and in making decisions about their participation are supported by these findings from Kenya. Important emerging considerations include the need to take account of the nature of proposed studies and prevailing attitudes and understanding of research in identifying children’s and adolescents’ roles. More research is needed to expand diversity and develop approaches to joint assent and consent processes that would fairly represent children’s and adolescents’ wishes and interests, towards their long term benefit.

BackgroundCarefully planned research is critical to developing policies and interventions that counter physical, psychological and social challenges faced by young people living with HIV/aids, without increasing burdens. Such studies, however, must navigate a ‘vulnerability paradox’, since including potentially vulnerable groups also risks unintentionally worsening their situation. Through embedded social science research, linked to a cohort study involving Adolescents Living with HIV/aids (ALH) in Kenya, we develop an account of researchers’ responsibilities towards young people, incorporating concepts of vulnerability, resilience, and agency (...) as ‘interacting layers’.MethodsUsing a qualitative, iterative approach across three linked data collection phases including interviews, group discussions, observations and a participatory workshop, we explored stakeholders’ perspectives on vulnerability and resilience of young people living with HIV/aids, in relation to home and community, school, health care and health research participation. A total of 62 policy, provider, research, and community-based stakeholders were involved, including 27 ALH participating in a longitudinal cohort study. Data analysis drew on a Framework Analysis approach; ethical analysis adapts Luna’s layered account of vulnerability.ResultsALH experienced forms of vulnerability and resilience in their daily lives in which socioeconomic context, institutional policies, organisational systems and interpersonal relations were key, interrelated influences. Anticipated and experienced forms of stigma and discrimination in schools, health clinics and communities were linked to actions undermining ART adherence, worsening physical and mental health, and poor educational outcomes, indicating cascading forms of vulnerability, resulting in worsened vulnerabilities. Positive inputs within and across sectors could build resilience, improve outcomes, and support positive research experiences.ConclusionsThe most serious forms of vulnerability faced by ALH in the cohort study were related to structural, inter-sectoral influences, unrelated to study participation and underscored by constraints to their agency. Vulnerabilities, including cascading forms, were potentially responsive to policy-based and interpersonal actions. Stakeholder engagement supported cohort design and implementation, building privacy, stakeholder understanding, interpersonal relations and ancillary care policies. Structural forms of vulnerability underscore researchers’ responsibilities to work within multi-sectoral partnerships to plan and implement studies involving ALH, share findings in a timely way and contribute to policies addressing known causes of vulnerabilities.

The potential of the folic acid biosynthesis pathway as a target for the development of antibiotics has been acknowledged for many years and validated by the clinical use of several drugs. Recently, the crystal structures of all but one of the enzymes in the pathway from GTP to dihydrofolate have been determined. Given that structure‐based drug design strategies are now widely employed, these recent developments have prompted a re‐evaluation of the potential of each of the enzymes in the pathway as (...) a target for development of specific inhibitors. Here, we review the current knowledge of the structure and mechanism of each enzyme in the bacterial folic acid biosynthesis pathway from GTP to dihydrofolate and draw conclusions regarding the potential of each enzyme as a target for therapeutic intervention.

Extending a normal 24 hours day by four hours is unexpectedly highly disruptive to daily rhythms in gene expression in the blood. Using a paradigm in which human subjects were exposed to a 28 hours day, Archer and colleagues show how this sleep‐altering forced desynchrony protocol caused complex disruption to daily rhythms in distinct groups of genes. Such perturbations in the temporal organisation of the blood transcriptome arise quickly, and point to the fragile nature of coordinated genomic activity. Chronic disruption (...) of the daily and circadian rhythms in sleep compromise health and well‐being and this study reveals potential new molecular targets to combat the disruptive effects of shift work and jetlag.

Philosophical Perspectives on Art presents a series of essays devoted to two of the most fundamental topics in the philosophy of art: the distinctive character of artworks and what is involved in understanding them as art. In Part I, Stephen Davies considers a wide range of questions about the nature and definition of art. Can art be defined, and if so, which definitions are the most plausible? Do we make and consume art because there are evolutionary advantages to doing (...) so? Has art completed the mission that guided its earlier historical development, and if so, what is to become of it now? Should architecture be classified as an art form? -/- Part II turns to the interpretation and appreciation of art. What is the target and purpose of the critic's interpretation? Is interpretation primarily directed at uncovering artists' intended meanings? Can apparently contradictory interpretations of a given piece both be true? Are interpretative evaluations entailed by descriptions of a work's aesthetic and artistic characteristics? In addition to providing fresh answers to these and other central questions in aesthetics, Davies considers the nature and content of metaphor, and the relation between the expressive qualities of a work of art and the emotions of its creator.

Constitutional dialogue has become an influential concept to understand the relationship between courts and other the institutional branches of the state, with the primary focus being on legislatures. More recently, the place of dialogue within the constitutional literature has been challenged as vague; providing a potential to over-reach or overstate the judicial role and distorting the reality of practices which in fact shape the relationship between courts and other institutions. Critics have placed into focus the question: should constitutional scholarship abandon (...) ‘constitutional dialogue’ as a way of understanding the relationship between courts and other institutions within the constitutional order? This article seeks to respond to this question by arguing that constitutional dialogue remains an important aspect of understanding the development of constitutional understanding about inter-institutional roles but does so by acknowledging the criticisms levelled against constitutional dialogue. Developing this approach, the argument made in this article seeks to recast the theoretical foundations of dialogue in constitutional theory by shifting the understanding of dialogue away from its normative and descriptive tethers. In its place, constitutional dialogue should be considered in the context of a philosophical understanding of language and the role that it plays to create constitutional meanings and experiences. Dialogue has a deeper and more significant register than a metaphor conveying a ‘conversation’, ‘communication’ or a ‘deliberative rationality’ between the institutions of the constitutional order—dialogue must be understood through the perspective of language as disclosing a world of common meaning and experience.

In recent years it has become increasingly the norm in football1 to kick the ball out of play when a player is, or appears to be, inadvertently injured. Kicking the ball out of play in football represents a particular instantiation of a generally understood fair play norm, the voluntary suspension of play (VSP). In the philosophical literature, support for the VSP norm is provided by John Russell (2007) who claims that his interpretivist account of sport is helpful for evaluating complex (...) moral issues in sport in general and issues related to injury in football in particular. This paper examines whether Russell's interpretivist-backed account of autonomy can adequately inform football players as to the nuanced and ambiguous moral considerations that arise in relation to the VSP norm. The paper goes on to identify the highly complex dynamic circumstances football players need to consider in order to better discharge their moral responsibilities when faced with inadvertent injuries.

How do historians approach objectivity? This is addressed by Mark Bevir in his book The Logic of the History of Ideas by his argument for an anthropological epistemology with objectivity in the historical narrative resting on the explanation of human actions/agent intentionality equating with meaning. The criticism of this position is at several levels. As sophisticated constructionists historians do not usually ask ‘Can history be objective?’ Rather, they work from the balance of evidence reflecting the intersubjectivity of truth and they (...) acknowledge the problematic nature of inferring agent intentionality and the difficulties in equating this with ‘what it means’. Why Abraham Lincoln issued the 1863 emancipation proclamation is a case in point. No historian would claim to have located its true meaning objectively in effect doubting Mark Bevir's claim that ‘objective knowledge arises from a human practice in which we criticise and compare rival webs of theories in terms of agreed facts’ . There are also further challenges to an over-reliance on rational action theory and the problems associated with the selection of evidence. Equally, most historians in practice doubt objectivity emerges from an accurate knowledge of the motives that can be matched to weak authorial intentions and that this leads to action via decisions. Few historians today accept that their narrative mimics past intentionality and that this provides true meaning. The article offers four reasons for rejecting Bevir's position and concludes with a defence of the narrative-linguistic determination of meaning. This suggests that history is subject to the same narrative and imaginative constraints as other forms of realist writing, rather than being privileged by an access to knowable intentionality and that this constitutes objective historical knowledge.

Narrative and History explains the key concepts and practices in the composition and writing of history. It explores how knowledge of the ways in which historians author history affects many conventional understandings of its nature. Major concepts such as truth, objectivity, reference and representation are re-evaluated and re-thought in radical ways. Combining theory with practice, Alun Munslow expands the boundaries of the discipline and charts a new role for unconventional historical forms and modes of expression.

This paper investigates the medical law and ethics learning needs of Foundation doctors by means of a national survey developed in association with key stakeholders including the General Medical Council and Health Education England. Four hundred sevnty-nine doctors completed the survey. The average self-reported level of preparation in MEL was 63%. When asked to rate how confident they felt in approaching three cases of increasing ethical complexity, more FYs were fully confident in the more complex cases than in the more (...) standard case. There was no apparent relationship with confidence and reported teaching at medical school. The less confident doctors were no more likely to ask for further teaching on the topic than the confident doctors. This suggests that FYs can be vulnerable when facing ethical decisions by being underprepared, not recognising their lack of ability to make a reasoned decision or by being overconfident. Educators need to be aware of this and provide practical MEL training based on trainee experiences and real-world ethics and challenge learners’ views. Given the complexities of many ethical decisions, preparedness should not be seen as the ability to make a difficult decision but rather a recognition that such cases are difficult, that doubt is permissible and the solution may well be beyond the relatively inexperienced doctor. Educators and supervisors should therefore be ensuring that this is clear to their trainees. This necessitates an environment in which questions can be asked and uncertainty raised with the expectation of a supportive response. (shrink)

I identify an inconsistency in Jago’s theory of truth. I show that Jago is committed to the identity of the proposition that the proposition that A is true and the proposition that A. I show that Jago is committed to the proposition that A being true because A if the proposition that A is true. I show that these two commitments, given the rest of Jago’s theory, entail a contradiction. I show that while the latter commitment follows from Jago’s theory (...) of truth, even by Jago’s own lights he should not be committed to the identity of the proposition that the proposition that A is true and the proposition that A.

I begin by examining perception of photographs from two directions: what we think photographs are, and the aspects of mind involved when viewing photographs. Traditional photographs are shown to be mnemonic tools, and memory identified as a key part of the process by which photographs are fully perceived. Second, I describe the metamorphogram; a non-traditional photograph which fits specific, author-defined criteria for being memory. The metamorphogram is shown to be analogous to a composite of all an individual’s episodic memories. Finally, (...) using the metamorphogram in artistic works suggests a bi-directional relationship between individual autobiographical memory and shared cultural memory. A model of this relationship fails to align with existing definitions of cultural memory, and may represent a new form: sociobiographical memory. I propose that the experiences documented here make the case for promoting a mutually beneficial relationship between philosophy and other creative disciplines, including photography. (shrink)

The Routledge Companion to Historical Studies provides a much-needed critical introduction to the major historians and philosophers together with the central issues, ideas and theories that have prompted the rethinking of history that has gathered pace since the 1990s. With twenty-nine new entries, and many that have been substantially updated, key concepts for the new history are examined through the ideas of leading thinkers such as Kant, Nietzsche, Croce, Collingwood, White, Foucault and Derrida, and through subjects ranging over class, empiricism, (...) hermeneutics, inference, relativism and technology. New entries for the second edition include: * Carl Becker * Frank R. Ankersmit * Jean-François Lyotard * gender * justified belief * the aesthetic turn * race * film * biography * cultural history * critical theory and experimental history. With a revised introduction setting out the state of the discipline of history today, as well as an extended and updated bibliography, this is the essential reference work for all students of history.

FIFA President Sepp Blatter’s recent attempt to resurrect the 6 + 5 quota for club football which limits the number of home-grown players to six is a protectionist measure at odds with global trends in free trade and freedom of movement. We remain unconvinced that his goals—to arrest the decline in the competitive quality and balance of international football, ensure greater investment in developing native talent and safeguarding national identity—are a problem or served well by such a regulation. We show (...) that the impact of foreign players on national teams is mixed and restrictions are as likely to undermine the quality of national teams as much as they will improve them. Our moral case will show he is wrong to assert that elite club football’s prime agenda ought to be a nationalist one. We conclude that the primary threat to the integrity, competitive balance and cultural significance of football is not labour migration but misplaced financial imperatives that have an overriding impact on shaping footba..

In recent years consciousness has become a significant area of study in the cognitive sciences. The Frontiers of Consciousness is a major interdisciplinary exploration of consciousness. The book stems from the Chichele lectures held at All Souls College in Oxford, and features contributions from a 'who's who' of authorities from both philosophy and psychology. The result is a truly interdisciplinary volume, which tackles some of the biggest and most impenetrable problems in consciousness. The book includes chapters considering the apparent explanatory (...) gap between science and consciousness, our conscious experience of emotions such as fear, and of willed actions by ourselves and others. It looks at subjective differences between two ways in which visual information guides behaviour, and scientific investigation of consciousness in non-human animals. It looks at the challenges that the mind-brain relation presents for clinical practice as well as for theories of consciousness. The book draws on leading research from philosophy, experimental psychology, functional imaging of the brain, neuropsychology, neuroscience, and clinical neurology. Distinctive in its accessibility, authority, and its depth of coverage, Frontiers of Consciousness will be a groundbreaking and influential addition to the consciousness literature. (shrink)

A fundamental cognitive function found across a wide range of species and necessary for survival is the ability to navigate complex environments. It has been suggested that mobility may play an important role in the development of spatial skills. Despite evolutionary arguments offering logical explanations for why sex/gender differences in spatial abilities and mobility might exist, thus far there has been limited sampling from nonindustrialized and subsistence-based societies. This lack of sampling diversity has left many unanswered questions regarding the effects (...) that environmental variation and cultural norms may have in shaping mobility patterns during childhood and the development of spatial competencies that may be associated with it. Here we examine variation in mobility, performance on large-scale spatial skills, and performance on small-scale spatial skills among Twa forager/pastoralist children whose daily lives have been dramatically altered since settlement and the introduction of government-funded boarding schools. Unlike in previous findings among Twa adults, boys and girls show similar patterns of travel on all measures of mobility. We also find no significant differences in spatial task performance by gender for large- or small-scale spatial skills. Further, children performed as well as adults did on mental rotation, and they outperformed adults on the water-level task. We discuss how children’s early learning environments may influence the development of both large- and small-scale spatial skills. (shrink)

How do we think about the word politeia when this involves a reaching back to the past? The response, pursued in this paper, is that in the classical understanding of politeia there is a significant connection between the question of the ‘good’ and the constitution; a connection which has become occluded or obscured by modern constitutional thought. In support of this understanding of politeia it must be acknowledged that what is meant, in this paper, by ‘good’ is very different from (...) that conventionally found in contemporary constitutional, legal or political theory. In an effort to disclose how politeia unravels this novel sense of ‘the good’ the paper will closely consider the philosophical work of Hans-Georg Gadamer on Plato. The paper claims that this largely neglected work is of importance to contemporary constitutional philosophy, particularly in so far as it focuses, as in this paper, on classical traditions or origins within constitutional thought.

Western philosophers have traditionally concentrated on theory as the means for expressing knowledge about a variety of phenomena. This absorbing book challenges this fundamental notion by showing how objects themselves, specifically scientific instruments, can express knowledge. As he considers numerous intriguing examples, Davis Baird gives us the tools to "read" the material products of science and technology and to understand their place in culture. Making a provocative and original challenge to our conception of knowledge itself, _Thing Knowledge _demands that we (...) take a new look at theories of science and technology, knowledge, progress, and change. Baird considers a wide range of instruments, including Faraday's first electric motor, eighteenth-century mechanical models of the solar system, the cyclotron, various instruments developed by analytical chemists between 1930 and 1960, spectrometers, and more.

This study aimed to develop a valid and reliable performance analysis template for quantifying team action variables in elite men’s wheelchair basketball. First action variables and operational definitions were identified by the authors and verified by an expert panel of wheelchair basketball coaching staff in order to establish expert validity.

The action variables were then used to develop a computerized performance analysis template for post-event (...) analysis. Each possession (n = 200) from an international men’s wheelchair basketball game was analyzed by the first author on two occasions for assessment of intra-observer reliability and by a coach and a performance analyst for inter-observer reliability. Percentage error and Weighted Kappa coefficients were calculated to compare the levels of error and agreement for each action variable. Intra-observer reliability demonstrated perfect or almost perfect agreement (. (shrink)

Utilitarianism has an apparent pedigree when it comes to animal welfare. It supports the view that animal welfare matters just as much as human welfare. And many utilitarians support and oppose various practices in line with more mainstream concern over animal welfare, such as that we should not kill animals for food or other uses, and that we ought not to torture animals for fun. This relationship has come under tension from many directions. The aim of this article is to (...) add further considerations in support of that tension. I suggest three ways in which utilitarianism comes significantly apart from mainstream concerns with animal welfare. First, utilitarianism opposes animal cruelty only when it offers an inefficient ratio of pleasure to pain; while this may be true of eating animal products, it is not obviously true of other abuses. Second, utilitarianism faces a familiar problem of the inefficacy of individual decisions; I consider a common response to this worry, and offer further concerns. Finally, the common utilitarian argument against animal cruelty ignores various pleasures that humans may get from the superior status that a structure supporting exploitation confers. (shrink)

An examination of the state of journalism and the need for change. For students and professionals on journalism fields.

In the BBC show, The Repair Shop, members of the public bring their cherished but crumbling possessions into a workshop populated by expert craftspeople, who carry out restorations. These objects arrive as treasured possessions, which, despite their dilapidated state, still hold memories and meaning for their owners, albeit memories that may have faded as the object itself has aged. Something magical seems to take place after the objects are restored, however. The restored objects seem to reanimate and revive the memories (...) that their owners have invested in them. How is it possible that this restoration can bring memories held by the objects back to life? What is special about The Repair Shop restoring objects to their former glory? We outline two ways in which objects can be evocative and embody emotion, memory, and meaning. We then outline the ways in which the restoration of these objects to something like their original form can improve scaffolded recall and bring memories back to life. For one class of evocative objects, the restoration enhances recall by reinstating details from the context in which the memories were encoded. For the second class of evocative objects, their restoration affords an imaginative connection to the past, which enables them to become powerful focal points of memory and shared narratives. In effect, The Repair Shop seems to work not only as a repair shop of objects but as a repair shop of memory too. (shrink)

In this paper we explore the idea that Pentecostalism is best supported by conjoining it to a postmodern, narrative epistemology in which everything is a text requiring interpretation. On this view, truth doesn’t consist in a set of uninterpreted facts that make the claims of Christianity true; rather, as James K. A. Smith says, truth emerges when there is a “fit” or proportionality between the Christian story and one’s affective and emotional life. We argue that Pentecostals should reject this account (...) of truth, since it leads to either a self-refuting story-relativism or the equally problematic fallacy of story-ism: favoring one’s own story over others without legitimate reason. In either case, we contend, the gospel itself is placed at risk. (shrink)

In this paper, I defend the agent/patient distinction against critics who argue that causal interactions are symmetrical. Specifically, I argue that there is a widespread type of causal interaction between distinct entities, resulting in a type of ontological asymmetry that provides principled grounds for distinguishing agents from patients. The type of interaction where the asymmetry is found is when one of the entities undergoes a change in kind, structure, powers, or intrinsic properties as a result of the interaction while the (...) other does not. Interactions of this type are widespread in molecular biology and chemistry. I focus specifically on (i) the actions of enzymes on substrates and (ii) water molecules breaking the bonds of polarized molecules. Finally, I respond to objections by laying out and to a limited extent defending three commitments of my account: emergent entities and powers, realism about chemical kinds or structures, and the assumption of the agent/patient distinction in functional attributions in biology.

I argue that the debate between proponents of substance causation and proponents of causation by powers, as to whether substances or their powers are causes, hinges on whether or not powers are self-exemplifying or non-self-exemplifying properties. Substance causation is committed to powers being non-self-exemplifying properties while causation by powers is committed to powers being self-exemplifying properties. I then argue that powers are non-self-exemplifying properties, in support of substance causation.
