Background The review of human participant research by Research Ethics Committees or Institutional Review Boards is a complex multi-faceted process that cannot be reduced to an algorithm. However, this does not give RECs/ IRBs permission to be inconsistent in their specific requirements to researchers or in their final opinions. In England the Health Research Authority coordinates 67 committees, and has adopted a consistency improvement plan including a process called “Shared Ethical Debate” where multiple committees review the same project. Committee reviews (...) are compared for consistency by analysing the resulting minutes. Methods We present a description of the ShED process. We report an analysis of minutes created by research ethics committees participating in two ShED exercises, and compare them to minutes produced in a published “mystery shopper” exercise. We propose a consistency score by defining top themes for each exercise, and calculating the ratio between top themes and total themes identified by each committee for each ShED exercise. Results Our analysis highlights qualitative differences between the ShED 19, ShED 20 and “mystery shopper” exercises. The quantitative measure of consistency showed only one committee across the three exercises with more than half its total themes as top themes. The average consistency scores for the three exercises were 0.23, 0.35 and 0.32. There is a statistically significant difference between the ShED 19 exercise, and the ShED 20 and mystery shopper exercises. Conclusions ShED exercises are effective in identifying inconsistency between ethics committees and we describe a scoring method that could be used to quantify this. However, whilst a level of inconsistency is probably inevitable in research ethics committee reviews, studies must move beyond the ShED methodology to understand why inconsistency occurs, and what an acceptable level of inconsistency might be.

Successful clinical trials are important for all of us, but they can be extremely complicated to design and run, so work must be done to consider what commonly goes wrong and how these issues can be addressed. Gelinas et al suggest an ethical argument for institutional prioritisation of clinical trials conducted among limited populations. This is to ensure successful recruitment and prevent competing trials rendering each other irrelevant through lack of statistical power. But they overlook the fact that effective prioritisation (...) already occurs, and their suggestion produces yet another hurdle for researchers to overcome. Their argument hinges around the claim that allocation of participants to trials represents an inevitable rationing scenario and, like all rationing scenarios, the best methods should be used for objectively determining how limited resources are distributed to achieve the end goal.1 Although they acknowledge that both individuals and clinicians may have preferences as to which trial a patient participates in, trial interventions are by definition experimental, and therefore choosing between trials is not really analogous to choosing between alternative clinical interventions. Here it seems that although clinical instinct is important when determining treatment options, a clinical trial is a specific attempt to create systematic justified knowledge and thus individual patient/clinician autonomy ….

BackgroundPublication and outcome reporting bias is often caused by researchers selectively choosing which scientific results and outcomes to publish. This behaviour is ethically significant as it distorts the literature used for future scientific or clinical decision-making. This study investigates the practicalities of using ethics applications submitted to a UK National Health Service research ethics committee to monitor both types of reporting bias.MethodsAs part of an internal audit we accessed research ethics database records for studies submitting an end of study declaration (...) to the Hampshire A research ethics committee between 1st January 2010 and 31st December 2011. A literature search was used to establish the publication status of studies. Primary and secondary outcomes stated in application forms were compared with outcomes reported in publications.ResultsOut of 116 studies the literature search identified 57 publications for 37 studies giving a publication rate of 32 %. Original Research Ethics Committee applications could be obtained for 28 of the published studies. Outcome inconsistencies were found in 16 of the published studies.ConclusionsThis study showed that the problem of publication and outcome reporting bias is still significant in the UK. The method described here demonstrates that UK NHS research ethics committees are in a good position to detect such bias due to their unique access to original research protocols. Data gathered in this way could be used by the Health Research Authority to encourage higher levels of transparency in UK research. (shrink)

We have followed with interest the commentaries arising from Moore and Donnellys1 argument that authorities in charge of research ethics committees should focus primarily on establishing code-consistent reviews.1 We broadly agree with Savulescu’s2 argument that ethics committees should become more expert, but in a different way and for a different reason. We have recently been working with the UK Health Research Authority analysing the outcomes of their ‘Shared Ethical Debate’ exercises.3 Each ShED exercise involves the circulation of a single research (...) project to a number of RECs. The resulting minutes from each REC are compared along with the final decisions made by each REC on the project under consideration. This process was originally an administrative exercise designed to promote greater consistency among the 60 or so ethics committees that were brought under the HRA ) umbrella within the UK National Health Service. Over 20 ShEDs have been run, and although the process has significant weaknesses and has not always been run consistently, the results of the exercises are fascinating. Broadly speaking, NHS RECs have been getting more consistent over time in terms of their decision-making, but the reasons for the final decisions as described in the committee minutes continue to vary widely. Qualitative research now needs to be done to understand why different committees can have such different discussions in relation to exactly the same research project and yet come to essentially the same conclusion. As part of our analysis of the ShED data, we looked at …. (shrink)

In this article, we develop tame topology over dp-minimal structures equipped with definable uniformities satisfying certain assumptions. Our assumptions are enough to ensure that definable sets are tame: there is a good notion of dimension on definable sets, definable functions are almost everywhere continuous, and definable sets are finite unions of graphs of definable continuous “multivalued functions.” This generalizes known statements about weakly o-minimal, C-minimal, and P-minimal theories.

Valid consent requires the potential research participant understands the information provided. We examined current practice in 50 proposed Clinical Trials of Investigational Medicinal Products to determine how this understanding is checked. The majority of the proposals ( n = 44) indicated confirmation of understanding would take place during an interactive conversation between the researcher and potential participant, containing questions to assess and establish understanding. Yet up until now, research design and review have not focussed upon this, concentrating more on written (...) material. We propose ways this interactive conversation can be documented, and the process of checking understanding improved. (shrink)

De Marco and colleagues claim that the standard account of invasiveness as commonly encountered ‘…does not capture all uses of the term in relation to medical interventions1 ’. This is open to challenge. Their first example is ‘non-invasive prenatal testing’. Because it involves puncturing the skin to obtain blood, De Marco et al take this as an example of how an incision or insertion is not sufficient to make an intervention invasive; here is a procedure that involves an incision, but (...) it is regarded as non-invasive. However, this ignores the context, and the term should really be understood in reference to the fetus. It is hard to believe healthcare professionals regard taking blood to measure, for example, ferritin levels as invasive but taking blood to look for fragments of fetal DNA as not. If anyone uses the term thinking it is not invasive to the mother, the solution would be to call it invasive, not redefine what is invasive. De Marco and colleagues’ second example is describing electroconvulsive therapy (ECT) as invasive. However, this is not borne out by their referenced papers. The first cited source is about non-invasive brain stimulation2 and only contains a single sentence about ECT. This sentence may suggest that their view is that ECT …. (shrink)

Research consent processes must provide potential participants with the necessary information to help them decide if they wish to join a study. On the Oxford ‘A’ Research Ethics Committee we’ve found that current research proposals mostly provide adequate detail (even if not in an easily comprehensible format), but often fail to support decision making, a view supported by published evidence. In a previous paper, we described how consent might be structured, and here we develop the concept of an Information and (...) Decision Aid (IDA) that can support decision making and be used to guide the dialogue between researcher and potential participant. Our proposal requires limited changes to current processes or paperwork and would provide an easily accessible document for others that the potential participant might approach for advice. It could later be integrated with the Informed Consent Form to ensure all matters of concern to the individual participant have been addressed before consent is formally signed off. (shrink)

BackgroundWe conducted a survey to identify what types of health/medical research could be exempt from research ethics reviews in Australia.MethodsWe surveyed Australian health/medical researchers and Human Research Ethics Committee members. The survey asked whether respondents had previously changed or abandoned a project anticipating difficulties obtaining ethics approval, and presented eight research scenarios, asking whether these scenarios should or should not be exempt from ethics review, and to provide comments. Qualitative data were analysed thematically; quantitative data in R.ResultsWe received 514 responses. (...) Forty-three per cent of respondents to whom the question applied, reported changing projects in anticipation of obstacles from the ethics review process; 25% reported abandoning projects for this reason. Research scenarios asking professional staff to provide views in their area of expertise were most commonly exempted from ethics review ; scenarios involving surplus samples and N-of-1 studies were most commonly required to undergo ethics review. HREC members were 26% more likely than researchers to require ethics review. Need for independent oversight, and low risk, were most frequently cited in support of decisions to require or exempt from ethics review, respectively.ConclusionsConsiderable differences exist between researchers and HREC members, about when to exempt from review the research that ultimately serves the interests of patients and the public. It is widely accepted that evaluative research should be used to reduce clinical uncertainties—the same principle should apply to ethics reviews. (shrink)

Taking regular walks when living with Parkinson’s disease has beneficial effects on movement and quality of life. Yet, patients usually show reduced physical activity compared to healthy older adults. Using auditory stimulation such as music can facilitate walking but patients vary significantly in their response. An individualized approach adapting musical tempo to patients’ gait cadence, and capitalizing on these individual differences, is likely to provide a rewarding experience, increasing motivation for walk-in PD. We aim to evaluate the observance, safety, tolerance, (...) usability, and enjoyment of a new smartphone application. It was coupled with wearable sensors and delivered individualized musical stimulation for gait auto-rehabilitation at home. Forty-five patients with PD underwent a 1-month, outdoor, uncontrolled gait rehabilitation program, using the BeatWalk application. The music tempo was being aligned in real-time to patients’ gait cadence in a way that could foster an increase up to +10% of their spontaneous cadence. Open-label evaluation was based on BeatWalk use measures, questionnaires, and a six-minute walk test. Patients used the application 78.8% of the prescribed duration and enjoyed it throughout the program. The application was considered “easy to use” by 75% of the patients. Pain, fatigue, and falls did not increase. Fear of falling decreased and quality of life improved. After the program, patients improved their gait parameters in the six-minute walk test without musical stimulation. BeatWalk is an easy to use, safe, and enjoyable musical application for individualized gait rehabilitation in PD. It increases “walk for exercise” duration thanks to high observance.Clinical Trial Registration: ClinicalTrials.gov Identifier: NCT02647242. (shrink)

Despite the challenges associated with virtually mediated communication, remote collaboration is a defining characteristic of online multiplayer gaming communities. Inspired by the teamwork exhibited by players in first-person shooter games, this study investigated the verbal and behavioral coordination of four-player teams playing a cooperative online video game. The game, Desert Herding, involved teams consisting of three ground players and one drone operator tasked to locate, corral, and contain evasive robot agents scattered across a large desert environment. Ground players could move (...) throughout the environment, while the drone operator’s role was akin to that of a “spectator” with a bird’s-eye view, with access to veridical information of the locations of teammates and the to-be-corralled agents. Categorical recurrence quantification analysis was used to measure the communication dynamics of teams as they completed the task. Demands on coordination were manipulated by varying the ground players’ ability to observe the environment with the use of game “fog.” Results show that catRQA was sensitive to changes to task visibility, with reductions in task visibility reorganizing how participants conversed during the game to maintain team situation awareness. The results are discussed in the context of future work that can address how team coordination can be augmented with the inclusion of artificial agents, as synthetic teammates. (shrink)

Finally, I share work we are doing to contribute towards filling that theoretical gap.

'Eye hEar The Visual in Music' employs the concept of the visual in proximate relation to music, producing a tension: 'is it not the case that there is a gulf between painting and music, between the visible and the audible? One is full of colour and light yet silent; one is invisible and marvellously noisy.' Such a belief, this book argues, betrays an ideological constraint on music, desiccating it to sound, and art to vision. The starting point of this study (...) is more hybrid (and hydrating): that music is never employed without numerous and complex intersections with the visual. By involving the concept of synaesthesia, the book evokes music's multi-sensory nature, stops it from sounding alone, and offers music as a subject for art historians. Music bleeds into art and visuality, in its graphic depiction in notation, in the theatre of performance, its sights and sites. This book looks at music in its absolute guise as a model for art; at notation and the conductor as the silent visual fulcra around which music circulates; at the music and image of Erik Satie; at the concert hall as white cube; at the symphonic film '2001: A Space Odyssey'; and at the liminality of John Cage and Andy Warhol.

The author analyzes the inner structure of the philosophy of the Tractatus rather than its relation to the views of other philosophers.

In everyday life we often act adequately, yet without deliberation. For instance, we immediately obtain and maintain an appropriate distance from others in an elevator. The notion of normativity implied here is a very basic one, namely distinguishing adequate from inadequate, correct from incorrect, or better from worse in the context of a particular situation. In the first part of this paper I investigate such ‘situated normativity’ by focusing on unreflective expert action. More particularly, I use Wittgenstein’s examples of craftsmen (...) (tailors and architects) absorbed in action to introduce situated normativity. Situated normativity can be understood as the normative aspect of embodied cognition in unreflective skillful action. I develop Wittgenstein’s insight that a peculiar type of affective behaviour, ‘directed discontent’, is essential for getting things right without reflection. Directed discontent is a reaction of appreciation in action and is introduced as a paradigmatic expression of situated normativity. In the second part I discuss Wittgenstein’s ideas on the normativity of what he calls ‘blind’ rule-following and the ‘bedrock’ of immediate action. What matters for understanding the normativity of (even ‘blind’) rule-following, is not that one has the capacity for linguistic articulation or reflection but that one is reliably participating in a communal custom. In the third part I further investigate the complex relationships between unreflective skillful action, perception, emotion, and normativity. Part of this entails an account of the link between normativity at the level of the expert’s socio-cultural practice and the individual’s situated and lived normativity. (shrink)

There are several theses in political science that are usually explicitly called ‘laws’. Other theses are generally thought of as laws, but often without being explicitly labelled as such. Still other claims are well-supported and arguably interesting, while no one would be tempted to call them laws. This situation raises philosophical questions: which theses deserve to be called laws and which not? And how should we decide about this? In this paper we develop and motivate a strategy for thinking about (...) laws in political science which integrates two core concepts: spatio-temporal stability and social mechanisms. The proposed strategy is a set of guidelines that political scientists can use to reflect on and argue about specific cases within their discipline, not a clear-cut demarcation criterion. We defend and motivate this strategy and apply it to two cases (one with respect to state repression, one about parliamentary elections). After we have developed and motivated our strategy for political science, we show that our proposal is relevant for other disciplines in the social sciences. We explain how our views fit into critical realism and embed them in the debate on laws in general philosophy of science and in the philosophy of the social sciences. (shrink)

C. S. Lewis is one of the most beloved Christian apologists of the twentieth century; David Hume and Bertrand Russell are among Christianity’s most important critics. This book puts these three intellectual giants in conversation with one another on various important questions: the existence of God, suffering, morality, reason, joy, miracles, and faith. Alongside irreconcilable differences, surprising areas of agreement emerge. Curious readers will find penetrating insights in the reasoned dialogue of these three great thinkers.

Simone Weil (1909-1943) was a defining figure of the twentieth century; a philosopher, Christian, resistance fighter, anarchist, feminist, labor activist and teacher. She was described by T. S. Eliot as "a woman of genius, of a kind of genius akin to that of the saints," and by Albert Camus as "the only great spirit of our time." Originally published posthumously in two volumes, these newly reissued notebooks, are among the very few unedited personal writings of Weil's that still survive today. (...) Containing her thoughts on art, love, science, God and the meaning of life, they give context and meaning to Weil's famous works, revealing a unique philosophy in development and offering a rare private glimpse of her singular personality.

Simone Weil is one of the most profound thinkers of the twentieth century. Her writings encompass an extraordinary breadth of subjects, including philosophy, religion, sociology, and politics. A political activist and resistance fighter, her accomplishments are even more astonishing in light of her death in 1943 at the age of thirty-four. Whilst Weil was concerned with deep philosophical questions - the nature of human thought and human faculties, the limits of language, and thought's contact with reality through mediation, science and (...) beauty - the full significance of her work has frequently been obscured by her categorization as a purely religious writer or Christian mystic. Simone Weil: Basic Writings is an expertly edited anthology of her most important writings, presenting Weil's philosophy as it relates to politics, the nature of work, human nature in its duality, necessity, beauty and goodness. D. K. Levy and Marina Barabas have translated all the extracts anew, including translations of important notes and references missing from existing English language editions of Weil's work. Following an extensive introduction by D. K. Levy which places Weil's life and thought in context, each section opens with a short introduction situating the chosen passages within Weil's oeuvre. Simone Weil: Basic Writings is an outstanding starting point for anyone seeking an introduction to Weil's philosophy, and also essential reading for students and scholars of Weil's thought in related disciplines.

Logical pluralism is the view that there is more than one correct logic. Most logical pluralists think that logic is normative in the sense that you make a mistake if you accept the premisses of a valid argument but reject its conclusion. Some authors have argued that this combination is self-undermining: Suppose that L1 and L2 are correct logics that coincide except for the argument from Γ to φ, which is valid in L1 but invalid in L2. If you accept (...) all sentences in Γ, then, by normativity, you make a mistake if you reject φ. In order to avoid mistakes, you should accept φ or suspend judgment about φ. Both options are problematic for pluralism. Can pluralists avoid this worry by rejecting the normativity of logic? I argue that they cannot. All else being equal, the argument goes through even if logic is not normative. (shrink)

The concept of ecosystem services is a way of visualizing the instrumental value that nature has for human beings. Most ecosystem services can be performed by more than one species. This fact is sometimes used as an argument against the preservation of species. However, even though substitutability does detract from the instrumental value of a species, it also adds option value to it. The option value cannot make a substitutable species as instrumentally valuable as a non-substitutable species, but in many (...) cases, it can add enough value to make the species more valuable than the projects that threaten its existence.

Particle indistinguishability has always been considered a purely quantum mechanical concept. In parallel, indistinguishable particles have been thought to be entities that are not properly speaking objects at all. I argue, to the contrary, that the concept can equally be applied to classical particles, and that in either case particles may (with certain exceptions) be counted as objects even though they are indistinguishable. The exceptions are elementary bosons (for example photons).

Angesichts der ökologischen Krise und der zunehmenden Zivilisationsprobleme ist es notwendig, einen philosophischen Naturbegriff, der das Verhältnis des Menschen zur Natur aufgrund dieser Tatsache neu bestimmt, zu entwickeln. Der Jesuit, Paläontologe und Philosoph Pierre Teilhard de Chardin (1881-1955) ist ein herausragendes Beispiel einer Vermittlung von Naturwissenschaft und Naturphilosophie. Teilhard entwirft eine Zusammenschau von transzendent-metaphysischer Teleologie, die aus dem christlichen Glauben heraus Gott als einzige Zweckursache des Geschehens sieht, philosophischer Anthropologie und naturwissenschaftlich orientierter kausalmechanischer Evolutionstheorie, dem allmählichen Entwickeln eines höheren Zustands (...) aus einem vorhergehenden. Die in der Ursache gegründeten Seinszusammenhänge ergeben einen vom Ziel her bestimmten Zusammenhang. Gott ist Totum alles wirklich Seienden im Horizont des möglichen Seins. Das für Teilhard so wichtige teleologische Prinzip hat seinen philosophiehistorischen Ursprung bei Aristoteles, der damit eine Denktradition begründete, die im Gegensatz zum kausal-mechanischen Weltbild der Naturwissenschaften steht und die sich über Thomas von Aquin und Hegel bis zu Teilhard als vorläufig letztem Höhepunkt erhält. Der aus Teilhards Naturphilosophie folgende Optimismus kann von großer Bedeutung für die Gegenwart sein. Er resultiert aus der Übernahme von Verantwortung für die Schöpfung und ist die ethische Konsequenz aus Naturfinalität und christlichem Universalismus. Der Autor: Erik Lehnert, geb. 1975 in Berlin.

I show that frequentism, as an explanation of probability in classical statistical mechanics, can be extended in a natural way to a decoherent quantum history space, the analogue of a classical phase space. The result is a form of finite frequentism, in which Gibbs’ concept of an infinite ensemble of gases is replaced by the quantum state expressed as a superposition of a finite number of decohering microstates. It is a form of finite and actual frequentism (as opposed to hypothetical (...) frequentism) insofar as all the microstates exist, in keeping with the decoherence-based Everett interpretation, and some versions of pilot-wave theory.

_The Radical Orthodoxy Reader _presents a selection of key readings in the field of Radical Orthodoxy, the most influential theological movement in contemporary academic theology. Radical Orthodoxy draws on pre-Enlightenment theology and philosophy to engage critically with the assumption and priorities of secularism, modernity, postmodernity, and associated theologies. In doing so it explores a wide and exciting range of issues: music, language, society, the body, the city, power, motion, space, time, personhood, sex and gender. As such it is both controversial (...) and extremely stimulating; provoking much fruitful debate amongst contemporary theologians.

We demonstrate that the quantum-mechanical description of composite physical systems of an arbitrary number of similar fermions in all their admissible states, mixed or pure, for all finite-dimensional Hilbert spaces, is not in conflict with Leibniz's Principle of the Identity of Indiscernibles (PII). We discern the fermions by means of physically meaningful, permutation-invariant categorical relations, i.e. relations independent of the quantum-mechanical probabilities. If, indeed, probabilistic relations are permitted as well, we argue that similar bosons can also be discerned in all (...) their admissible states; but their categorical discernibility turns out to be a state-dependent matter. In all demonstrated cases of discernibility, the fermions and the bosons are discerned (i) with only minimal assumptions on the interpretation of quantum mechanics; (ii) without appealing to metaphysical notions, such as Scotusian haecceitas, Lockean substrata, Postian transcendental individuality or Adamsian primitive thisness; and (iii) without revising the general framework of classical elementary predicate logic and standard set theory, thus without revising standard mathematics. This confutes: (a) the currently dominant view that, provided (i) and (ii), the quantum-mechanical description of such composite physical systems always conflicts with PII; and (b) that if PII can be saved at all, the only way to do it is by adopting one or other of the thick metaphysical notions mentioned above. Among the most general and influential arguments for the currently dominant view are those due to Schrodinger, Margenau, Cortes, Dalla Chiara, Di Francia, Redhead, French, Teller, Butterfield, Giuntini, Mittelstaedt, Castellani, Krause and Huggett. We review them succinctly and critically as well as related arguments by van Fraassen and Massimi. (shrink)
