Concussion is a form of mild traumatic brain injury that can occur as a result of contact to the head or other parts of the body that causes a rapid acceleration-deceleration force to the brain that may cause a functional disturbance in an individual’s ability to concentrate or learn new information. Contrary to popular belief, it is not a bruise to the brain, and there is usually nothing detectable on standard imaging such as a computed tomography or magnetic resonance imaging. (...) Symptoms and signs are therefore important to detect and include decreased levels of consciousness, headache, nausea, difficulty concentrating, memory loss, and poor coordination. These signs and symptoms usually occur within minutes after the injury but may also appear several hours or even days later. (shrink)

This study renders the complex corpus of the Guodian texts into a more easily manageable form, incorporating the past several years of scholarly activity on these texts and providing them with a comprehensive introduction along with a complete and well-annotated translation into English.

Macphail’s comparative approach to intelligence focused on associative processes, an orientation inconsistent with more multifaceted lay and scientific understandings of the term. His ultimate emphasis on associative processes indicated few differences in intelligence among vertebrates. We explore options more attuned to common definitions by considering intelligence in terms of richness of representations of the world, the interconnectivity of those representations, the ability to flexibly change those connections, knowledge, and individual differences. We focus on marine mammals, represented by the amphibious pinnipeds (...) and the aquatic cetaceans and sirenians, as animals that transitioned from a terrestrial existence to an aquatic one, experiencing major changes in ecological pressures. They adapted with morphological transformations related to streamlining the body, physiological changes in respiration and thermoregulation, and sensory/perceptual changes, including echolocation capabilities and diminished olfaction in many cetaceans, both in-air and underwater visual focus, and enhanced senses of touch in pinnipeds and sirenians. Having a terrestrial foundation on which aquatic capacities were overlaid likely affected their cognitive abilities. Vocal and behavioral observational learning capabilities in the wild and in laboratory experiments suggest versatility in group coordination. Empirical reports on aspects of intelligent behavior like problem-solving, spatial learning, and concept learning by various species of cetaceans and pinnipeds, suggest rich cognitive abilities. The high energy demands of the brain suggest brain-intelligence relationships might be fruitful areas for the study when specific hypotheses are considered, e.g., brain mapping indicates hypertrophy of specific sensory areas in marine mammals. Modern neuroimaging techniques provide ways to study neural connectivity, and the patterns of connections between sensory, motor, and other cortical regions provide a biological framework for exploring how animals represent and flexibly use information in navigating and learning about their environment. At this stage of marine mammal research, it would still be prudent to follow Macphail’s caution that it is premature to make strong comparative statements without more empirical evidence, but an approach that includes learning more about how animals flexibly link information across multiple representations could be a productive way of comparing species by allowing them to use their specific strengths within comparative tasks.

In this essay we introduce a new tool for studying the patterns of sentential reference within the framework introduced in [2] and known as the language of paradox $\mathcal {L}_{\mathsf {P}}$ : strong $\mathcal {L}_{\mathsf {P}}$ -homomorphisms. In particular, we show that (i) strong $\mathcal {L}_{\mathsf {P}}$ -homomorphisms between $\mathcal {L}_{\mathsf {P}}$ constructions preserve paradoxicality, (ii) many (but not all) earlier results regarding the paradoxicality of $\mathcal {L}_{\mathsf {P}}$ constructions can be recast as special cases of our central result regarding (...) strong $\mathcal {L}_{\mathsf {P}}$ -homomorphisms, and (iii) that we can use strong $\mathcal {L}_{\mathsf { P}}$ -homomorphisms to provide a simple demonstration of the paradoxical nature of a well-known paradox that has not received much attention in this context: the McGee paradox. In addition, along the way we will highlight how strong $\mathcal {L}_{\mathsf {P}}$ -homomorphisms highlight novel connections between the graph-theoretic analyses of paradoxes mobilized in the $\mathcal {L}_{\mathsf {P}}$ framework and the methods and tools of category theory.

Biomedical research is increasingly carried out in low- and middle-income countries. International consensus has largely been achieved around the importance of valid consent and protecting research participants from harm. But what are the responsibilities of researchers and funders to share the benefits of their research with research participants and their communities? After setting out the legal, ethical and conceptual frameworks for benefit sharing, this collection analyses seven historical cases to identify the ethical and policy challenges that arise in relation to (...) benefit sharing. A series of recommendations address possible ways forward to achieve justice for research participants in low- and middle-income countries. (shrink)

Individualism: The Cultural Logic of Modernity is an edited collection of sixteen essays on the idea of the modern sovereign individual in the western cultural tradition. Reconsidering the eighteenth-century realist novel, twentieth-century modernism, and underappreciated topics on individualism and literature, this volume provocatively revises and enriches our understanding of individualism as the generative premise of modernity itself.

Individuals with social anxiety disorder engage in post-event processing, a form of perseverative thinking. Given that deficits in working memory might underlie perseverative thinking, we examined working memory in SAD with a particular focus on the effects of stimulus valence. SAD and healthy control participants either maintained or reversed in working memory the order of four emotional or four neutral pictures, and we examined sorting costs, which reflect the extent to which performance deteriorated on the backward trials compared to the (...) forward trials. Emotionality of stimuli affected performance of the two groups differently. Whereas control participants exhibited higher sorting costs for emotional stimuli compared to neutral stimuli, SAD participants exhibited the opposite pattern. Greater attention to emotional stimuli in SAD might facilitate the processing of emotional stimuli in working memory. (shrink)

The excellent article in the January number of the Classical Quarterly upon a mistaken interpretation of Philebus 31 c contains the somewhat incorrect statement that this interpretation is the general one: and the article itself is anticipated by a short note in a paper which I published in the Transactions of the Oxford Philological Society for 1881–2. I have nothing to complain of, for it may partly serve me right. Besides, my paper, though duly registered in the Revue de Philologie, (...) is omitted from the index of that periodical; the aforesaid Transactions are out of print, and by some mischance my correction of the wrong rendering did not appear in the last edition of Jowett's Plato, though Jowett intended it should.

This dissertation is primarily concerned with the subjects of disagreement, argument, and the methodology of philosophy. The first chapter sets out and attempts to answer the question of what the connection between disagreement and disputing is. The second chapter is primarily a investigation into the nature of verbal disputes. The answer the chapter puts forward is that there is a justificatory relation between disagreeing and disputing, so that, for example, if two parties do not disagree in the right way, then (...) they should not dispute. In the second chapter I will look at a few theories of verbal disputes, and I will discuss some of the features such a theory should have. I go on to explicitly endorse a version of David Chalmers's theory of verbal disputes, and defend it from some potential objections. The third chapter is a defence of the method of conceptual analysis in philosophy. I introduce some potential objections to the Canberra plan style of conceptual analysis, and show how a different conception of conceptual analyses could get over these problems. The conception of conceptual analysis I argue for is heavily inspired by Rudolf Carnap's system of explication. The main way Carnapian explication would differ from the Canberra plan style of conceptual analysis is in the way that it would allow one to move further away from the original concept in analysing it, by balancing closeness to the original concept against other specific criteria.

It has been alleged that Carolus Linnaeus practised Eurocentrism, sexism and racism in naming plant genera after famous botanists, and excluding ‘barbarous names’. He has therefore been said to practise ‘linguistic imperialism’. This paper examines whether Linnaeus applied ‘linguistic imperialism’ to the naming of Chinese plants. On the basis of examples such as Thea (¼Camellia), Urena, Basella, Annona, Sapindus (¼Koelreuteria), and Panax, I conclude that Linnaeus used generic names of diverse origins. However, he misidentified Chinese plants’ habitats, and acted on (...) these misapprehensions. (shrink)
