BackgroundReturning neuroimaging incidental findings may create a challenge to research participants’ health literacy skills as they must interpret and make appropriate healthcare decisions based on complex radiology jargon. Disclosing IF can therefore present difficulties for participants, research institutions and the healthcare system. The purpose of this study was to identify the extent of the health literacy challenges encountered when returning neuroimaging IF. We report on findings from a retrospective survey and focus group sessions with major stakeholders involved in disclosing IF.MethodsWe (...) surveyed participants who had received a radiology report from a research study and conducted focus groups with participants, parents of child participants, Institutional Review Board members, investigators and physicians. Qualitative thematic analyses were conducted using standard group-coding procedures and descriptive summaries of health literacy scores and radiology report outcomes are examined.ResultsAlthough participants reported high health literacy skills, 67 % did not seek medical care when recommended to do so; and many participants in the focus groups disclosed they could not understand the findings described in their report. Despite their lack of understanding, participants desire to have information about their radiology results, and the investigators feel ethically inclined to return findings.ConclusionsThe language in clinically useful radiology reports can create a challenge for participants’ health literacy skills and has the potential to negatively impact the healthcare system and investigators conducting imaging research. Radiology reports need accompanying resources that explain findings in lay language, which can help reduce the challenge caused by the need to communicate incidental findings. (shrink)
Estimates of the burden of disease assess the mortality and morbidity that affect a population by producing summary measures of health such as quality-adjusted life years and disability-adjusted life years. These measures typically do not include stillbirths among the negative health outcomes they count. Priority-setting decisions that rely on these measures are therefore likely to place little value on preventing the more than three million stillbirths that occur annually worldwide. In contrast, neonatal deaths, which occur in comparable numbers, have a (...) substantial impact on burden of disease estimates and are commonly seen as a pressing health concern. In this article we argue in favor of incorporating unintended fetal deaths that occur late in pregnancy into estimates of the burden of disease. Our argument is based on the similarity between late-term fetuses and newborn infants and the assumption that protecting newborns is important. We respond to four objections to counting stillbirths: that fetuses are not yet part of the population and so their deaths should not be included in measures of population health; that valuing the prevention of stillbirths will undermine women's reproductive rights; that including stillbirths implies that miscarriages should also be included; and that birth itself is in fact ethically significant. We conclude that our proposal is ethically preferable to current practice and, if adopted, is likely to lead to improved decisions about health spending. (shrink)
We generalize an observation made by Goldblatt in "Diodorean modality in Minkowski spacetime" by proving that each -dimensional integral spacetime frame equipped with Robb's irreflexive `after' relation determines a unique temporal logic. Our main result is that, unlike -dimensional spacetime where, as Goldblatt has shown, the Diodorean modal logic is the same for each frame , in the case of -dimensional integral spacetime, the frame determines a unique Diodorean modal logic.
We consider the problem of axiomatizing various natural "successor" logics for 2-dimensional integral spacetime. We provide axiomatizations in monomodal and multimodal languages, and prove completeness theorems. We also establish that the irreflexive successor logic in the "standard" modal language (i.e. the language containing □ and ◊) is not finitely axiomatizable.
Nothing survives deconstruction unless we accept that survival in some sense attaches to the ghostly or etiolated figures (the marks and traces) of things, by which deconstruction proceeds. If the ghostly figure survives then it may be because it is undeconstructible. Yet the spectral figure would no doubt remain insignificant if it was not for the force it brings to bear on more central and familiar categories of philosophical and literary discourse. These categories, like style, friendship, justice and hospitality, tend (...) to occupy those spectral spaces that mark the structural difference between philosophy (conceptual, abstract, universal) and literature (figurative, concrete, singular). Yet nothing defines such spaces so well as the trace and its paradoxical structure. And nothing describes the structure of the trace so well as that of the signature. This paper identifies the movement of the trace as occupying and to a great extent defining the difference between philosophy and literature. The example, in this case, is the appearance of asphodels in Homer's Odyssey, according to which the fields where ghosts live are thick with the so-called grave-flower. But the asphodel on closer examination breaks down into mere traces of itself in a series of insoluble philological problems. The larger implications have to do with death, the signature of the writer, the relation between philosophy and literature and their respective modes of survival. There is no philosophy (no truth, no good, no chance) without its attachment to the etiolated figure, the trace of itself. The paper proposes readings of Blanchot, Derrida, Hegel and Plato, in addition to a focus on the main philological problem in Homer and its implications for a tradition of literary allusion, as a way of establishing the consistency of the paradoxical structure of the signature.

The main project of this dissertation is to analyze various temporal conceptions of modality for discrete n-dimensional spacetime. The first chapter contains an introduction to the problem and known results. Chapter 2 consists of a study of logics which are analogues of the so-called 'logic of today and tomorrow' and 'logic of tomorrow' investigated by Segerberg and others. We consider the analogues of these successor logics for 2-dimensional integral spacetime. We provide axiomatizations in monomodal and multimodal languages and prove completeness (...) theorems. We also establish that the irreflexive successor logic in the "standard" modal language is not finitely axiomatizable. ;Chapter 3 investigates the axiomatization problem for 2-dimensional integral spacetime frames with Robb's irreflexive 'after' relation. We provide an axiomatization in a multimodal language and prove that this axiomatization is complete. We use this result to prove the system in the "standard" modal language is decidable. ;In Chapter 4 we take up the problem of what the correct Diodorean modal logic is for 2-dimensional integral spacetime. We show that the corresponding Diodorean modal logic is not S4.2, nor indeed any known modal system. We then present several candidate axioms and prove their independence in the context of S4.2. We also study some of the sublogics of the Diodorean modal logic for 2-dimensional discrete spacetime . ;The final chapter contains some general results. First we prove that for every n ≥ 2 the n-dimensional frame determines a unique Diodorean modal logic. We also consider temporal logics in the language with F and P for two kinds of irreflexive spacetime frames. We prove that for every n ≥ 2 the n-dimensional frame with Robb's 'after' relation determines a unique temporal logic. We also prove a generalized completeness theorem for n-dimensional irreflexive successor logics. Finally, in an appendix, we provide a list of selected open problems and indicate directions for future research in this area. (shrink)
This book examines Proclus' doctrine of evil in light of the tradition of exegesis of Plato's treatment of evil within the schools of ancient Platonism, from ...
This study reconsiders Denis O'Brien's controversial thesis that it was Plotinus' position that the 'partial' soul generates matter. O'Brien relies principally on two core texts, 3.4 .1 and 3.9 .3, where he finds convincing evidence for his thesis. In the present study I take two approaches. First, I demonstrate that if we accept O'Brien's thesis, then we are compelled to accept as well that Plotinus is guilty of self-contradiction in his doctrine of soul's descent. Secondly, I offer a different interpretation (...) of what Plotinus has in mind as the source of matter's generation in 3.4.1 and 3.9.3. In several passages Plotinus states that the product of the partial soul's creative activity is the "trace" of soul that, in turn, combines with matter to form the 'qualified body.' I argue that it is this trace-soul, not matter, that Plotinus is referring to in these texts. (shrink)
Neoplatonic Exegeses of Plato's Cosmogony JOHN F. PHILLIPS AMONG THE MANY CONTROVERSIES to which the long history of interpretation of Plato's Timaeus has given rise, that concerning the eternity of the cosmos is one of the most enduring and complex, and the source of almost continuous debate from the time of Xenocrates to the present. The importance to all Platonists of a doctrinally consistent answer to the question of whether or not the universe had a beginning in time is made (...) amply clear in the statement attributed to Iamblichus by Proclus that proper understand- ing of the creation of the world is crucial for the entire theory of Nature. Iamblichus here refers obliquely to the orthodox Platonist position that the universe is not a temporal being subject to decay and destruction. The princi- pal problem for all of them, of course, was that, taken literally, Plato's account of the creation in the Timaeus, particularly the passage 27C-a8C, appears to be an unequivocal affirmation of a temporal beginning to the cosmos. Espe- cially troublesome was Plato's use of the verb y~yovev in Timaeus 28b 7, which seems to be an explicit claim for an &QX1] in time. That this passage did indeed refer to a temporal beginning was a point that was made repeatedly and forcefully by the chief opponents of the Platonists on this issue, the Peripa- tetics, who, following Aristotle, read the Timaeus creation account literally.'

The 1962 publication of J. H. Waszink's edition of Calcidius' commentary on Plato's "Timaeus" focussed attention on the question of Calcidius' source for a group of chapters where he presents an interpretation of Plato's account of the creation of soul. I discuss three attempts to answer this question: that of Waszink himself, who argues that the source is Porphyry who was here influenced by the Neopythagorean/Platonist Numenius, that of J. M. Van Winden, who claims Numenius as the direct source, and (...) that of Werner Deuse, who offers reasons for excluding Numenius as either directly or indirectly responsible. I show the weakness of Deuse's critique, but then argue that neither Waszink nor Van Winden has given sufficient consideration to the possibility that Plotinus, either alone or through Porphyry as intermediary, is behind Calcidius' interpretation, where the doctrines of the unity of the soul and of a higher soul that does not descend, both characteristic of Plotinus' psychology, are prominent. However, there is an important but uniformly overlooked feature of this exegesis that rules out both Plotinus and Porphyry as possible sources. This leaves Numenius as the only serious candidate. If, then, the origin of the doctrines of the unity of the soul and of the undescended higher soul can be traced to the work of Numenius, there is the strong possibility that in his formulation of these same doctrines Plotinus was indebted to Numenius.

Some modifications are suggested to recent (1985) generalised phrase-structure grammar which make the formalism more suitable to computational use, and at the same time provide a clear and elegant redefinition for parts of the formalism which are standardly complex and ill-defined. It is shown how the feature-instantiation principles can be represented as explicit rules in a format similar to metarules, and how a grammar of four parts, immediate-dominance rules, linear-precedence rules, metarules, and these new propagation rules, can be used to (...) produce the ordinary GPSG analyses of English. Methods of computational implementation are discussed, in particular it is suggested that the parts of the grammar are most conveniently interpreted as instructions as to how to produce a set of context-free phrase-structure rules which can be used with a simple left-corner parser.

What has been learned about logic by means of "uninterpreted" logistic systems can be supplemented by comparing the latter with systems which are more uninterpreted, as well as with others which are less uninterpreted than the well-known logistic systems. By somewhat extending the meaning of 'uninterpreted', I hope to establish certain claims about the nature of logistic systems and also to cast some light on the nature of "logic itself." My procedure involves looking at three major "degrees" of interpretation: first, (...) systems uninterpreted both semantically and syntactically, second, systems uninterpreted semantically but not syntactically, and third, systems uninterpreted neither semantically nor syntactically. We shall be forced to limit ourselves to the truth-functional part of logic in this brief study. What are usually called uninterpreted systems can be seen on a continuum of "degrees" of interpretation, from ordinary reasoning at one extreme to a "thoroughly uninterpreted system" at the other. "Logic itself" apparently lies nearer to the interpreted, deformalized end of the spectrum than to the uninterpreted, formalized end. Logic is not identical with any particular logistic system, but is that which the particular logistic systems aim to formalize or model or capture. I propose that it is that minimum set of logical, rather than syntactical, primitive terms, definitions, and rules which is needed to generate logically, rather than syntactically, the principles of ordinary reasoning as it is used by logicians in their metalinguistic discussions and informal proofs of metatheorems. This minimum set is somewhat larger than the primitive bases of most logistic systems; its truth-functional part is presented in the "Deformalized Logic" at degree twelve. (shrink)
Charles Taylor identifies a close connection between morality and politics, noting that much confusion arises from poorly understood, and sometimes clearly mistaken, moral ontologies. Together with fellow communitarians and civic-republicans, Taylor argues that the rights-based judicial review of legislation rests upon a fundamentally mistaken Rawlsian/Kantian moral ontology. While accepting Taylor’s critique of Rawls’ moral ontology and its questionable ability to defend judicial review, I develop an alternative reading of judicial review relying on insightful new work by Wilfrid Waluchow. I conclude (...) that if we accept Waluchow’s common- law conception of the judicial review, there is good reason for Taylor to reject some of his deprecating comments about judicial review. I further suggest that a common-law conception of the judicial review may be amicable to the larger Communitarian and Civic-republican project. (shrink)
This accessible and wide-ranging introduction to critical theory provides a comprehensive overview of the practice, role, and importance of theory across the humanities and social sciences. It not only maps a notoriously complex area, but it also enables the reader to take the arguments and apply them in practice. Starting with an explanation of how theory relies on implicit assumptions that inform interpretations, the book moves on to depict the long-term philosophical problems that have fed into much 20th century thinking (...) and also more recent debates. The philosophical grounds of contemporary thought are traced from Plato through Descartes to the work of Heidegger and Freud and on to recent developments in structuralism and deconstruction that critically revise many of the previous terms of debate.

For more than 30 years and until his death in 2004 Jacques Derrida remained one of the most influential contemporary philosophers. It may be difficult to evaluate what forms his heritage will take in the future but _Derrida Now_ provides some provocative suggestions. Derrida’s often-controversial early reception was based on readings of his complex works, published in journals and collected in books. More recently attention has tended to focus on his later work, which grew out of the seminars that he (...) presented each year in France and the US. The full texts of these seminars are now the subject of a major publication project, to be produced over the next ten years. _Derrida Now_ presents contemporary articles based on or around the study of Derrida. It provides a critical introduction to Derrida’s complex and controversial thought, offers careful analysis of some of his most important concepts, and includes essays that address the major strands of his thought. Derrida’s influence reached not only into philosophy but also into other fields concerned with literature, politics, visual art, law, ecology, psychoanalysis, gender and sexuality and this book will appeal to readers in all these disciplines. Contributors include Peggy Kamuf, Geoff Bennington, Sarah Wood, Roy Sellars, Graham Allen, and Irving Goh. (shrink)
