Three experiments investigated response times for remember and know responses in recognition memory. RTs to remember responses were faster than RTs to know responses, regardless of whether the remember–know decision was preceded by an old/new decision or was made without a preceding old/new decision . The finding of faster RTs for R responses was also found when remember–know decisions were made retrospectively. These findings are inconsistent with dual-process models of recognition memory, which predict that recollection is slower and more effortful (...) than familiarity. Word frequency did not influence RTs, but remember responses were faster for words than for nonwords. We argue that the difference in RTs to remember and know responses reflects the time taken to make old/new decisions on the basis of the type of information activated at test. (shrink)

Background: People with traumatic brain injury face a range of mental health challenges during the adjustment process post-injury, but access to treatment can be difficult, particularly for those who live in regional and remote regions. eHealth provides the potential to improve access to evidence-based psychological therapy for people with a severe TBI. The aim of the current study is to assess the efficacy of a psychological intervention delivered via video consulting to reduce psychological distress in people with TBI.Methods: This paper (...) outlines the protocol for a multi-center, three-arm, parallel, non-inferiority randomized controlled trial of an evidence-based manualized psychological intervention, ACT-Adjust. ACT-Adjust provides nine sessions for adults with a moderate to severe TBI experiencing clinical levels of psychological distress. Fifty-six participants referred from Brain Injury Rehabilitation Units across New South Wales and the NSW icare scheme will be randomly allocated to three conditions; video consulting, face-to-face and, a waitlist control.Discussion: This is the first RCT to evaluate the efficacy of a psychological therapy delivered via video consulting for individuals with a moderate to severe TBI.Trial Registration:www.anzctr.org.au, Australian New Zealand Clinical Trials Registry ANZCTRN2619001602112.

Randomized controlled trial trial designs exist on an explanatory-pragmatic spectrum, depending on the degree to which a study aims to address a question of efficacy or effectiveness. As conceptualized by Schwartz and Lellouch in 1967, an explanatory approach to trial design emphasizes hypothesis testing about the mechanisms of action of treatments under ideal conditions, whereas a pragmatic approach emphasizes testing effectiveness of two or more available treatments in real-world conditions. Interest in, and the number of, pragmatic trials has grown substantially (...) in recent years, with increased recognition by funders and stakeholders worldwide of the need for credible evidence to inform clinical decision-making. This increase has been accompanied by the onset of learning healthcare systems, as well as an increasing focus on patient-oriented research. However, pragmatic trials have ethical challenges that have not yet been identified or adequately characterized. The present study aims to explore the views of key stakeholders with respect to ethical issues raised by the design and conduct of pragmatic trials. It is embedded within a large, four-year project that seeks to develop guidance for the ethical design and conduct of pragmatic trials. As a first step, this study will address important gaps in the current empirical literature with respect to identifying a comprehensive range of ethical issues arising from the design and conduct of pragmatic trials. By opening up a broad range of topics for consideration within our parallel ethical analysis, we will extend the current debate, which has largely emphasized issues of consent, to the range of ethical considerations that may flow from specific design choices. Semi-structured interviews with key stakeholders, across multiple jurisdictions, identified based on their known experience and/or expertise with pragmatic trials. We expect that the study outputs will be of interest to a wide range of knowledge users including trialists, ethicists, research ethics committees, journal editors, regulators, healthcare policymakers, research funders and patient groups. All publications will adhere to the Tri-Agency Open Access Policy on Publications. (shrink)

The only constant in theological education is change, despite brave attempts to hold the tide back in some quarters. Yet, Western-based theological education remains the norm globally. The Faculty of Theology at the University of Pretoria exemplifies this norm despite its commitment to Africanisation. This article will consider transformation through the lens of the leadership of Prof. Johan Buitendag, who has led the transformation initiative from his own shared leadership perspective as dean since 2010. Change in the faculty will (...) be analysed through analysis of the faculty plans, with particular reference to teaching, learning and research. Consideration will be given to a more radical proposal for future transformation under the initiative of Africanisation. (shrink)

To judge from the dust-jacket, this book has received a considerable amount of praise--and not just from the usual suspects. In particular, the publishers seem keen to promulgate the view that there is widespread support for the claim that Overman makes a clear, compelling, and well-argued case for the conclusions which he wishes to defend. However, it seems to me that those cited on the dust-jacket--Pannenberg ("lucid and sobering arguments"), Polkinghorne ("scrupulously argued"), Nicholi ("compelling logic and carefully reasoned argument"), Kaita (...) ("cogent and lucid"), Gingerich ("interesting and convincing"), Behe ("compelling case"), and McGrath ("clear and informed arguments")--cannot have been commenting on the book which I am currently in the process of reviewing. True enough, the book is well-organised and mostly easy to read; moreover, the book clearly demonstrates that Overman is thoroughly acquainted with popular presentations of recent work in a variety of scientific fields. But the crucial question is whether it makes a clear, compelling, and well-argued case for the conclusions which Overman wishes to defend. I shall claim in this review that the book fails on all three counts. (shrink)

Offers a forthright approach to the many disquieting questions surrounding the emotional debate over animal rights. This book includes a chapter on animal agriculture, and additional discussions of animal law, companion animal issues, genetic engineering, animal pain, animal research, and other topics.

This is a short introduction to ontological arguments. It begins with a brief characterization of ontological arguments that proceeds mainly by way of example. The rest of the discussion is given over to consideration of what looks like a very simple ontological argument. This consideration turns up many of the issues that arise when more complex ontological arguments are examined.

Weak enough relevant logics are often closed under depth substitutions. To determine the breadth of logics with this feature, we show there is a largest sublogic of R closed under depth substitutions and that this logic can be recursively axiomatized.

The present study aimed to examine how to improve the effectiveness of moral exemplar-applied interventions based on the pillars of the Self-Determination Theory (SDT) framework, autonomy, competence, and relatedness. Past research has mainly focused on the relatedness and attainability of moral exemplars for predicting motivation outcomes. The data for this study consisted of synthesized data sets from previous studies examining the motivational impacts of distinct moral exemplars and intervention methods. The main syntheses for these data sets used Multilevel Modeling (MLM) (...) focusing on relatability, attainability, and intervention methods, corresponding to relatedness, competence, and autonomy in the SDT, respectively, as predictors. In general, there was a significant interaction effect between the attainability or relatability, and the intervention method. Autonomous instruction methods, which support autonomy, were demonstrated to boost motivational outcomes. Implications from this study support the employment of SDT to examine the use of moral exemplars in moral education and were consistent with previous exemplar studies. (shrink)

According to Fitting Attitude theorists, for something to possess a certain value it is necessary and sufficient that it be fitting to take a certain attitude to the bearer of that value. This seems obvious for thick evaluative attributes, but less obvious for thin evaluative attributes. This chapter argues that the fitting response to the thin evaluative attributes of states is desire. The good is what it is fitting to desire, the bad what it is fitting to be averse to, (...) and the better what it is fitting to prefer. For the FA schema to survive the challenges of “wrong kinds of reasons” and “solitary goods,” the fitting response to the goodness of a state has to be a non-factive, non-doxastic representation of the state as good. That desires and preferences are non-doxastic value appearances is independently attractive; this is the simplest hypothesis compatible with the Fitting Attitude approach. (shrink)

This monograph reappraises the role of Bertrand Russell's philosophical works in establishing the analytical tradition in philosophy. It's main aims are to: * improve our understanding of the history of analytical philosophy * engage in the important disputes surrounding the interpretation of Russell's philosophy * make a contribution to central issues in current analytical philosophy. Drawing extensively from Russell's less well known and unpublished works, this book is a welcome addition to the literature and will undoubtedly find a place on (...) the bookshelves of philosophers around the world.

ABSTRACT Is what we’re morally permitted to do grounded in our subjective situation? Subjectivists maintain that it is. Objectivists deny this. I shall offer two arguments for Objectivism about moral permissibility.

The AdS/CFT duality has been a source of several strong conceptual claims in the physics literature that have yet to be explored by philosophers. In this paper I focus on one of these: the extent to which spacetime geometry and locality can be said to emerge from this duality, so that neither is fundamental. I argue: that the kind of emergence in question is relatively weak, involving one kind of spacetime emerging from another kind of spacetime; inasmuch as there is (...) something conceptually interesting to say about the emergence of spacetime and locality , it is no different from that already well known to those within canonical quantum gravity; that at the core of AdS/CFT is an issue of representation and redundancy in representation.

This paper is about rewilding and the tensions it involves. Rewilding is a relatively novel approach to nature conservation, which seeks to be proactive and ambitious in the face of continuing environmental decline. Whilst definitions of rewilding place a strong emphasis on non-human agency, it is an inescapably human aspiration resulting in a range of social conflicts. The paper focuses on the case study of the Cambrian Wildwood project in Mid Wales (UK), evaluating the ways in which debate and strategic (...) action to advance rewilding is proceeding, assessing the extent to which compromise and learning has occurred amongst advocates. As such, we provide an important addition to the field, by detailing how conflicts play out over time and how actors' positioning and approach shifts, and why. In this case, tempers have flared around the threat that rewilding is seen to pose to resident farming communities. Tensions discussed include the differing social constructions of landscape and nature involved; the distribution of impacts on different stakeholders; and the relative power of different actors to make decisions and gain representation. Responding to these, the paper outlines how rewilding advocates have sought to advance a more peopled and culturally responsive vision, which seeks to champion sustainable livelihood strategies. The changes in approach detailed demonstrate a reflexive stance from rewilders, which suggests that learning and adaptation can occur. Nonetheless, caution is expressed regarding the extent to which rewilding can truly advance inclusive opportunities for rural change, given a continued return amongst stakeholders to exclusionary narratives of belonging and authenticity, suggesting substantive difficulty in moving beyond longstanding concerns over identity and the re-imagination of place. Rewilding, it would seem, is about who we think we are and how we co-constitute our sense of self. We, therefore, close by arguing that tactics and politicking can only have so much bearing, tensions over rewilding are unavoidably emotional. (shrink)

Prognosis after severe brain injury is highly uncertain, and decisions to withhold or withdraw life‐sustaining treatment are often made prematurely. These decisions are often driven by a desire to avoid a situation where the patient becomes ‘trapped’ in a condition they would find unacceptable. However, this means that a proportion of patients who would have gone on to make a good recovery, are allowed to die. I propose a shift in practice towards the routine provision of aggressive care, even in (...) cases where the probability of survival and acceptable recovery is thought to be low. In conjunction with this shift, I argue in favour of a presumption towards withdrawing life‐sustaining treatment, including artificial nutrition and hydration, when it becomes clear that a patient will not recover to a level that would be acceptable to them. I then respond to three potential objections to this proposal. (shrink)

The dominance of string theory in the research landscape of quantum gravity physics (despite any direct experimental evidence) can, I think, be justified in a variety of ways. Here I focus on an argument from mathematical fertility, broadly similar to Hilary Putnam’s ‘no miracles argument’ that, I argue, many string theorists in fact espouse in some form or other. String theory has generated many surprising, useful, and well-confirmed mathematical ‘predictions’—here I focus on mirror symmetry and the mirror theorem. These predictions (...) were made on the basis of general physical principles entering into string theory. The success of the mathematical predictions are then seen as evidence for the framework that generated them. I shall attempt to defend this argument, but there are nonetheless some serious objections to be faced. These objections can only be evaded at a considerably high (philosophical) price. (shrink)

What is the 'philosophy of sport'? What does one do to count as a practitioner in the philosophy of sport? What conception of philosophy underpins the answer to those questions? In this important new book, leading sport philosopher Graham McFee draws on a lifetime's philosophical inquiry to reconceptualise the field of study. The book covers important topics such as Olympism, the symbolisation of argument, and epistemology and aesthetics in sport research; and concludes with a section of 'applied' sport philosophy (...) by looking at rules and officiating. Using a Wittgensteinian framework, and employing a rich array of sporting examples throughout, McFee challenges the assumptions of traditional analytic philosophy regarding the completeness required of concepts and the exceptionlessness required of philosophical claims, providing the reader with a new set of tools with which to approach this challenging subject. On Sport and the Philosophy of Sport is fascinating and important reading for any serious students or researchers of sport philosophy. (shrink)

Hybrid expressivists claim to solve the Frege-Geach problem by offloading the explanation of the logico-semantic properties of moral sentences onto beliefs that are components of hybrid states they express. We argue that this strategy is undermined by one of hybrid expressivism’s own commitments: that the truth of the belief-component is neither necessary nor sufficient for the truth of the hybrid state it composes. We articulate a new approach. Instead of explaining head-on what it is for, say, a pair of moral (...) sentences to be inconsistent, expressivists should “sidestep” and explain what it is _to think that_ a pair of moral sentences is inconsistent. To think so is to think they cannot both be true – a modal notion. Since expressivists have given accounts of such modals, we illustrate how sentences like ‘“lying is wrong” and “lying is not wrong” are inconsistent’ express sensible – and rationally compelling – states of mind.

‘Quantum Gravity’ does not denote any existing theory: the field of quantum gravity is very much a ‘work in progress’. As you will see in this chapter, there are multiple lines of attack each with the same core goal: to find a theory that unifies, in some sense, general relativity (Einstein’s classical field theory of gravitation) and quantum field theory (the theoretical framework through which we understand the behaviour of particles in non-gravitational fields). Quantum field theory and general relativity seem (...) to be like oil and water, they don’t like to mix—it is fair to say that combining them to produce a theory of quantum gravity constitutes the greatest unresolved puzzle in physics. Our goal in this chapter is to give the reader an impression of what the problem of quantum gravity is; why it is an important problem; the ways that have been suggested to resolve it; and what philosophical issues these approaches, and the problem itself, generate. This review is extremely selective, as it has to be to remain a manageable size: generally, rather than going into great detail in some area, we highlight the key features and the options, in the hope that readers may take up the problem for themselves—however, some of the basic formalism will be introduced so that the reader is able to enter the physics and (what little there is of) the philosophy of physics literature prepared. I have also supplied references for those cases where I have omitted some important facts. Hence, this chapter is intended primarily as a catalyst for future research projects by philosophers of physics, both budding and well-matured. (shrink)

The issue of regularly feeding low levels of antibiotics to farm animals in order to increase productivity is often portrayed as a dilemma. On the one hand, such antibiotic use is depicted as a necessary condition for producing cheap and plentiful food, such that were such use to stop, food prices would rise significantly and our ability to feed people in developing nations would decrease. On the other hand, such antibiotic use seems to breed antibiotic resistance into pathogens affecting human (...) health. Resolving this dilemma, it is alleged, will require great amounts of research into risk/benefit assessment. Contrary to this claim, we will argue that society has all the data it needs to make a reasonable ethical decision, which would be curtailing such use. Such curtailment will not harm consumers significantly, will not harm developing nations'' evolving agriculture, and could produce hitherto unnoticed benefits, namely restoring the possibility of a more husbandry-based, sustainable agriculture to replace the high-tech agriculture that has hurt animals, the environment, small farms, and sustainability.

Categorial logic, as its name suggests, applies the techniques and machinery of category theory to topics traditionally classified as part of logic. We claim that these tools deserve attention from a greater range of philosophers than just the mathematical logicians. We support this claim with an example. In this paper we show how one particular tool from categorial logic---hyperdoctrines---suggests interesting metaphysics. Hyperdoctrines can provide semantics for quantified languages, but this account of quantification suggests a metaphysical picture quite different from the (...) one suggested by standard model-theoretic semantics.

Speculations about the role of consciousness in physical systems are frequently observed in the literature concerned with the interpretation of quantum mechanics. While only three experimental investigations can be found on this topic in physics journals, more than 800 relevant experiments have been reported in the literature of parapsychology. A well-defined body of empirical evidence from this domain was reviewed using meta-analytic techniques to assess methodological quality and overall effect size. Results showed effects conforming to chance expectation in control conditions (...) and unequivocal non-chance effects in experimental conditions. This quantitative literature review agrees with the findings of two earlier reviews, suggesting the existence of some form of consciousness-related anomaly in random physical systems. (shrink)

Hsueh M. Qu has recently argued that Hume’s famed ‘Separability Principle’ from the Treatise entangles him in a contradiction. Qu offers a modified principle as a solution but also argues that the mature Hume would not have needed to avail himself of it, given that Hume’s arguments in the first Enquiry do not depend on this principle in any form. To the contrary, I show that arguments in the first Enquiry depend on this principle, but I agree with Qu that (...) Qu’s solution to Hume’s quandary frees him of the contradiction. Next, I compare Qu’s solution to Hume’s original position. By analysing the divergent forms of 'Hume’s Dictum’ that follow from them, I show that Qu’s solution and Hume’s original position have significantly different consequences in a range of domains, including Hume’s modality. Generally, Qu’s solution fits better with Hume’s other commitments—even though Hume often fails to recognize it—thereby increasing its plausibility. (shrink)

Frege’s Basic Law V and its successor, Boolos’s New V, are axioms postulating abstraction operators: mappings from the power set of the domain into the domain. Basic Law V proved inconsistent. New V, however, naturally interprets large parts of second-order ZFC via a construction discovered by Boolos in 1989. This paper situates these classic findings about abstraction operators within the general theory of F-algebras and coalgebras. In particular, we show how Boolos’s construction amounts to identifying an initial F-algebra in a (...) certain category, we identify a natural coalgebraic dual to Boolos’s axiom which naturally interprets large parts of Aczel’s non-well-founded set theory via the construction of a certain terminal F-coalgebra, and we suggest a coalgebraic way forward for an abstraction-theoretic axiomatization of the real numbers.

Where does the study of the flow of time belong: physics, the cognitive sciences, philosophy, or somewhere else? Physicists and philosophers have set themselves up into two camps: those who believe there is genuine flow or becoming in the world and those who believe there is just a block of events. What had not been considered is whether the subjective feeling of flow of time is the same the world over, whether it could be tampered with by brain injury, or (...) whether it is present at all developmental stages. We lay out the problem, explain terms, and provide synopses of relevant ideas. (shrink)

Background independence is generally considered to be ‘the mark of distinction’ of general relativity. However, there is still confusion over exactly what background independence is and how, if at all, it serves to distinguish general relativity from other theories. There is also some confusion over the philosophical implications of background independence, stemming in part from the definitional problems. In this paper I attempt to make some headway on both issues. In each case I argue that a proper account of the (...) observables of such theories goes a long way in clarifying matters. Further, I argue, against common claims to the contrary, that the fact that these observables are relational has no bearing on the debate between substantivalists and relationalists, though I do think it recommends a structuralist ontology, as I shall endeavour to explain.

Bertrand Russell's 1903 masterpiece "The Principles of Mathematics" places great emphasis on the need to separate propositions from psychological items such as thoughts. In 1919 Russell explicitly retracts this view, however, and defines propositions as "psychological occurrences". These psychological occurrences are held by Russell to be mental images. In this paper, I seek to explain this radical change of heart. I argue that Russell's re-psychologising of the proposition in 1919 can only be understood against the background of his struggle with (...) the problem of the unity of the proposition in earlier work. Once this is recognized, and the solution to the problem offered by the 1919 theory is appreciated, new light is also shed on Russell's naturalism. I go on to compare Russell's psychological "picture theory" with the vehemently anti-psychological picture theory of Wittgenstein's "Tractatus Logico-Philosophicus" and suggest that, once the background of the dispute is brought into clearer focus, Russell's position can be seen to have many advantages over its more celebrated rival.
