All rights reserved.We present new observations of the low-mass companion to HD 984 taken with the Gemini Planet Imager as a part of the GPI Exoplanet Survey campaign. Images of HD 984 B were obtained in the J and H bands. Combined with archival epochs from 2012 and 2014, we fit the first orbit to the companion to find an 18 au orbit with a 68% confidence interval between 14 and 28 au, an eccentricity (...) of 0.18 with a 68% confidence interval between 0.05 and 0.47, and an inclination of 119°with a 68% confidence interval between 114°and 125°. To address the considerable spectral covariance in both spectra, we present a method of splitting the spectra into low and high frequencies to analyze the spectral structure at different spatial frequencies with the proper spectral noise correlation. Using the split spectra, we compare them to known spectral types using field brown dwarf and low-mass star spectra and find a best-fit match of a field gravity M6.5 ±1.5 spectral type with a corresponding temperature of K. Photometry of the companion yields a luminosity of log=2.88 ± 0.07 dex with DUSTY models. Mass estimates, again from DUSTY models, find an age-dependent mass of 34 ±1 to 95 ±4 M Jup. These results are consistent with previous measurements of the object. (shrink)

Goethe and Wittgenstein -- Criticism without theory -- Wittgenstein's romantic inheritance -- Arnold and the socratic personality -- The dissolution of goodness : measure for measure and classical ethics -- Lamarque and Olsen on literature and truth -- The definition of 'art' -- Poetry and abstraction -- Larkin's 'Aubade'.

The influence of Goethe on Wittgenstein is just beginning to be appreciated. Hacker and Baker, Westphal, Monk, and Haller have all drawn attention to significant affinities between the two men's work, and the number of explicit citations of Goethe in Wittgenstein's texts supports the idea that we are not dealing simply with a matter of deeplying similarities of aim and method, but of direct and major influence. These scholarly developments are encouraging because they help to place Wittgenstein's work within an (...) important tradition of German letters which goes far beyond his contemporaries and immediate forebears in Vienna; and they show that Wittgenstein's profound interest in literature and music is ceasing to be merely a matter of biographical anecdote, and is being used to illuminate some of the most central areas of his work.

Among bioethicists and members of the public, genetics is often regarded as unique in its ethical challenges. As medical researchers and clinicians increasingly combine genetic information with a range of non-genetic information in the study and clinical management of patients with common diseases, the unique ethical challenges attributed to genetics must be re-examined. A process of genetic routinisation that will have implications for research and clinical ethics, as well as for public conceptions of genetic information, is constituted by the emergence (...) of new forms of genetic medicine, in which genetic information is interpreted in a multifactorial frame of reference. Although the integration of genetics in medical research and treatment may be a helpful corrective to the mistaken assumptions of genetic essentialism or determinism, the routinisation of genetics may have unintended consequences for the protection of genetic information, perceptions of non-genetic information and the loss of genetic research as a laboratory for exploring issues in research and clinical ethics. Consequently, new ethical challenges are presented by the increasing routinisation of genetic information in both biomedical and public spheres. (shrink)

After presenting a variety of arguments in support of the idea that ordinary names are indexical, I respond to John Perry's recent arguments against the indexicality of names. I conclude by indicating some connections between the theory of names defended here and Wittgenstein's observations on naming, and suggest that the latter may have been misconstrued in the literature.

The theory of personal identity should illuminate and be illuminated by the theory of personality, of which it is a part. I believe that Locke's theory succeeds in this more than that of any other great philosopher, and the modifications which it may need are not fundamental ones. The problems raised by Butler and Flew can be made to disappear.

Precision Medicine has become a common label for data-intensive and patient-driven biomedical research. Its intended future is reflected in endeavours such as the Precision Medicine Initiative in the USA. This article addresses the question whether it is possible to discern a new ‘medical cosmology’ in Precision Medicine, a concept that was developed by Nicholas Jewson to describe comprehensive transformations involving various dimensions of biomedical knowledge and practice, such as vocabularies, the roles of patients and physicians and the conceptualisation of disease. (...) Subsequently, I will elaborate my assessment of the features of Precision Medicine with the help of Michel Foucault, by exploring how precision medicine involves a transformation along three axes: the axis of biomedical knowledge, of biomedical power and of the patient as a self. Patients are encouraged to become the managers of their own health status, while the medical domain is reframed as a data-sharing community, characterised by changing power relationships between providers and patients, producers and consumers. While the emerging Precision Medicine cosmology may surpass existing knowledge frameworks; it obscures previous traditions and reduces research-subjects to mere data. This in turn, means that the individual is both subjected to the neoliberal demand to share personal information, and at the same time has acquired the positive ‘right’ to become a member of the data-sharing community. The subject has to constantly negotiate the meaning of his or her data, which can either enable self-expression, or function as a commanding Superego. (shrink)

Pure Type Systems, PTSs, were introduced as a generalization of the type systems of Barendregt's lambda cube and were designed to provide a foundation for actual proof assistants which will verify proofs. Systems of illative combinatory logic or lambda calculus, ICLs, were introduced by Curry and Church as a foundation for logic and mathematics. In an earlier paper we considered two changes to the rules of the PTSs which made these rules more like ICL rules. This led to four kinds (...) of PTSs. Most importantly PTSs are about statements of the form M:A, where M is a term and A a type. In ICLs there are no explicit types and the statements are terms. In this paper we show that for each of the four forms of PTS there is an equivalent form of ICL, sometimes if certain conditions hold. (shrink)

The passing on of information to GPs by genito-urinary doctors is to be encouraged but is not always possible and ultimately the patient's wishes and confidentiality must be respected if sexually transmitted diseases and HIV infection are to be controlled. Infected health-care workers should seek counselling and medical support and clear guidelines from professional organisations which are in existence. However, they will only do so if strict confidentiality is maintained and assurance about future employment can be given.

The idea underlying this article was that the humanities in general and business ethics in particular should be more firmly embedded in business management programs. A number of areas have been identified for students to use as topics for research projects in management ethics. These ranged from Biblical and classical times to the present day. Some were drawn from sources that were less well known e.g. the De consolatione philosphiae ‘The Consolation of Philosophy’ by Boethius 524 AD. This was chosen (...) partly for its ethical content, but also because Boethius was magister officiorum i.e. head of the civil service. Aelfred the Great (849–899) King of Wessex (he who burnt those cakes) was chosen because he promoted the intellectual, moral and spiritual qualities that were to serve as guidelines for his executives. Nineteenth century literature (Dickens, Thackeray, Trollope and Galsworthy) was also chosen as a source of topics for research projects in business ethics. The writer acknowledges the work of earlier writers in the fields of management, organisation theory, and business ethics. (shrink)

The classical relativistic theory is developed of electric and magnetic fields in terms of boost and rotation generators, respectively, of the Lorentz group of space-time. This development shows that Minkowski geometry requires that there be threestates of polarization of radiation in free space. The magnetic components in a circular basis are right and left circular and longitudinal. The longitudinal component is real and physical, and proportional to one of the three, nonzero, rotation generators of the Lorentz group. The longitudinal electric (...) component is pure imaginary, and proportional to one of the three boost generators. These theoretical arguments conform with experimental data from the Planck radiation law and from magnetic effects of light such as the inverse Faraday effect. (shrink)
