© 2017. The American Astronomical Society. 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)

A book which might well become a classic on Heidegger. Richardson discusses most of Heidegger's works in chronological order, offering a close analysis of each. Most chapters include a general exposition of the argument of the work discussed, a detailed analysis of the problems of Thought, Being and Dasein in the work, and a résumé. While maintaining very high standards of scholarly precision in the rendering of Heidegger's ideas and terminology, Richardson yet succeeds in making his book very readable and (...) lucid. Without "supplementing" Heidegger in any way, refraining from explanatory speculations and staying always very close to the text, he manages to clarify some of the most difficult passages of Heidegger's works. His frequent cross-references make the commentary of genuine value to the advanced student as well as to the novice. Heidegger, in his own preface to the book, criticizes Richardson for the sharp distinction between Heidegger I and Heidegger II, but gives a most important substantiation to two of the author's main theories, viz., the difference between Heidegger's Seinsdenken and Husserl's phenomenology, and the central status of the concept of Ereignis in Heidegger's philosophy. Richardson regrettably does not pursue the Heidegger III suggested by Vycinas, the Heidegger of the Geviert, the question of the nature of Being as such. In some chapters at least this omission makes the interpretation seem partial and sometimes inexact. One hopes for a sequel as good and illuminating.—E. M. Z. (shrink)

Unlike most anthologies in aesthetics and the philosophy of art, the present selection does not try to collect representative extracts from the writings of most, or even many, important aestheticians throughout the ages. It aims for depth rather than width and tries to do as much justice as possible to those aestheticians which it does include, without bothering much about those left out. The result is really impressive. No less than 138 pages are devoted to Plato and Aristotle alone, where (...) the reader may find not only the usual passages from the Poetics and the Rhetoric but also relevant material from De Partibus Animalium and Politica. Such an anthology, so it seems, must be an opinionated one. Thus, while it contains some 70 pages of Dewey's Art as Experience, there is not a single line of Santayana in it. Although I disagree with the choice made in this case, I cannot but admire the courage it took to make it. Another surprise is the inclusion of the relatively obscure mediaeval thinker, Marsilio Ficino, in an anthology which excludes Baumgarten, Lessing, Burke, Schiller, Coleridge, Bosanquet and Alexander, to mention but few, and whose sole contemporary representative is Heidegger. The extracts from Ficino's commentary on Plato prove, however, to be highly interesting and relatively original, too. Thus, even if Ficino is not as great as some of the aestheticians not included in this volume, I, for one, would not regret this mark of personal, off-beat, taste. The last selection, Heidegger's "The Origin of the Work of Art," appearing for the first time in English translation, comes as special bonus to the reader. The editors' introductions to each selection are generally concise, precise, and very helpful. Sometimes, however, one may find an exception: in their introduction to the Heidegger translation, the editors characterize the Kehre as a "reversal... from the stress on anxiety, nothingness... to a stress on more affirmative moods." This is, to say the least, a grossly misleading remark, which is likely to confuse the student of the later Heidegger rather than help him.—E. M. Z. (shrink)

A collection of commentaries on various theories in aesthetics, similar in method and aim to Kainz's Vorlesungen. Far from placing "the study of aesthetics on a new footing" or grasping "the scope of the subject as a whole," as the dust jacket declares, it is still a useful, well organized and often illuminating manual for the student of aesthetics. Sparshott treats some problems clearly and succinctly, but many other questions, such as the mode of being of the work of art (...) or the possibility of regarding art as a cognitive form, are not even mentioned. It also seems that some familiarity with at least the main currents in aesthetics on the continent and a more systematic conception of the field of aesthetics as a whole would have brought Sparshott closer to his stated aims.—E.

Although some of Helmholtz’s scientific suggestions are dated with the progress of science, his ontological statements as well as his epistemological studies are still an object of philosophical controversy. The selection of Helmholtz’s epistemological writings, edited as volume 79 in the Synthese Library, contains four papers originally published in German between 1868 and 1887. In these papers are considered among others the epistemological aspects of measuring and numbering, the issues of perceptual cognition, the theory of geometrical knowledge, and the relationship (...) between science and metaphysics. The present collection of the Helmholtz’s articles was previously edited in German, on the centenary of his birth, under the title Schriften zur Erkenntnistheorie. The editors, M. Schlick and P. Hertz, sharing the opinion that Helmholtz’s name is a symbol of a union between epistemologically oriented philosophy and science, had selected from his many epistemological writings only four—the most representative and the most complete. In order to make the papers intelligible not only to philosophers but also to general readers, Schlick and Hertz supplemented the primary texts with explanatory remarks and comments. Some of them have a general introductory character, explaining, for instance, the difference between induction and deduction or elucidating Locke’s conception of two kinds of properties; the others present useful syntheses of methodological solutions, comparing, e.g., Carnap’s or Reichenbach’s ideas with Helmholtz’s.

This book contains twenty-two papers by K. Ajdukiewicz, an outline of his memoir and philosophical evolution by J. Giedymin, and a bibliography of Ajdukiewicz’s works compiled by T. Czezowski. In the colorful introductory paper, Giedymin characterizes the personality of the famous Polish philosopher-logician as a person open not only to philosophical investigations but also to contemplation of the beauty contained in music, literature, and nature. The sketch of Ajdukiewicz’s scientific activity presents him as an excellent teacher, open-minded in understanding different (...) viewpoints but simultaneously as an independent and uncompromising thinker.

Parry’s volume is not an elementary book, but it is apparently intended as an introduction to Locke’s political thought for students. While he definitely has a point of view of his own, he attempts to draw together much of the recent critical thought on Locke. Parry’s volume differs from much of the recent work on Locke in being, one might say, "sweet-tempered." He is sweet-tempered in the first place toward Locke. Unlike so much of the recent scholarly-historical literature, he clearly (...) respects Locke. In a field marked by acrimony among scholars, Parry is also remarkably sweet tempered toward other Locke scholars; he builds on the work of others where possible, rather than emphasizing his own novelty and uniqueness. He thus produces a far more balanced treatment than most. For example, he accepts willingly the Laslett-sponsored arguments that the Second Treatise is aimed against Filmer as was the First, but he refuses to toss out entirely the older view that it is aimed in some measure against Hobbes. Although Parry is probably least tolerant towards the Strauss approach to Locke, he is even able to find large areas where he endorses moderate versions of that position, for example, on the important range of similarities between Hobbes and Locke. Parry’s "harmonizing approach" shows up also in the unusually wide range of Lockean sources from which he draws. He uses not only the standard fare of the Second Treatise and the Essays on the Law of Nature, but also the works on education, toleration, and economics to good effect. Disappointingly scanty, however, is the place of the First Treatise and even the Essay. His harmonizing approach shows up most importantly, however, in his attempt to combine the two chief sorts of attention Locke has received in recent years. On the one hand, there is the Locke scholarship properly so-called. While there are several varieties and orientations within this literature, no doubt the leading one has taken a very historical approach—attempting to understand Locke in his historical context and deploying religious or theological categories as the chief means for doing so. This approach shuns "present-mindedness" above all other intellectual vices. While Parry announces his general adherence to this approach he attempts to take account of the other main sort of interest in Locke today—as a source and inspiration for a very live contemporary tradition of political thinking, represented by Nozick and Rawls. Parry uses these contemporary "Lockeans" to help interpret the Second Treatise, leaning for example on Rawls’s formulation of the problem social contact theory attempts to answer, and Nozick’s doctrine of "entitlements." Parry’s refusal to be terrified by the strictures against "present-mindedness" produce some of the best and most valuable features of the book, as when he seriously asks what Locke means today, or how other contemporary political views differ from Locke’s. On the other hand, his reading of Locke on political economy suffers a bit perhaps from over-domination by Nozick’s restatement. Parry attempts to give both devils their due by agreeing with the historical school that Locke’s thought must be read historically, as Christian or theological, in a form that could hardly be acceptable to any contemporary political thinkers, and agreeing with the contemporary Lockean tradition that "to a very considerable extent" Locke’s position "can and must be…assessed and understood apart from its theological substructure." Those theological foundations are, Parry admits, very problematical. In fact, with a post-Humean eye, "it can become difficult to persuade oneself even that Locke could have found his position consistent." Yet Parry affirms "there is no doubt that Locke found the argument satisfying." But he supplies no reason—other than the fact that Locke deployed such arguments on more than one occasion—for this conclusion. Surely gross inconsistencies in argument are grounds for doubt. Parry should have at the least entertained Leo Strauss’s hypothesis about Locke’s manner of expression in light of his own views that Locke’s expressed theological underpinnings are unacceptable philosophically, and that Locke’s position can rest on altogether independent nontheological grounds. Moreover, Parry’s concession that Locke cannot move successfully from those religious underpinnings to the all-important content of the law of nature supplies further grounds for considering the same hypothesis. Parry’s treatment shares with most of the historical approaches to Locke the defect of "slackness"—when we come to something inconsistent or difficult to understand, we write it off as the product of Locke’s faith, internally meaningful, believable to him. Only in Parry’s case this is more problematical yet, for he rightly insists that we see Locke’s position as nonarchaic, and thus makes the reader eager for probing analysis and justification rather than loose appeals to Locke’s times. In order to connect the theological underpinnings to the political arguments, Parry is driven to some most un-Lockean notions such as the duty of "an individual to stretch himself to the full." For a similar reason, we suspect, freedom, which plays an extremely large part in Parry’s exposition, nowhere receives an adequate rooting in Locke’s discussion in the Essay, nor does Locke’s hedonism play a sufficient part in Parry’s interpretation.—M.Z.

A repulsive core force is derived which, assuming π mesons are the field particles, gives binding energies in good agreement with binding energies per nucleon of heavy nuclei. The physical model consists of a field of relatively short range, in which emission of a π meson by a nucleon and subsequent absorption by a neighboring nucleon is equivalent to a potential well. The binding energy at the equilibrium spacing of the nucleons is the self-energy of the π mesons, which is (...) calculated by analogy with classical electric fields. (shrink)

The first six chapters of this book present and criticize six views of the nature of proper names, among which are theories that proper names have no meaning or connotation, that proper names have more meaning than other signs or that their meaning is infinite, that ordinary proper names should be analysed into "logically" proper names, etc. This part of the book is the best. One may find in these chapters several well-reasoned arguments which seem to totally demolish the theories (...) under investigation. Chapters seven to nine present the author's own solution to the problem. Sørensen holds that a proper name does have a meaning—otherwise it would not have been a part of language at all. The meaning of a linguistic sign, he argues, is a set of conditions to be satisfied by an extra-linguistic entity, such that this entity may be identified as denoted by the said sign. A proper name is an individual name, and its meaning is a series of necessary and sufficient conditions for the identification of the individual entity which this name is intended to denote. It is Sørensen's view that this series consists of a definite description of final length including space and time indicators. The definiens formula for proper names is thus 'P' = 'the x that... t... p....' The discussion of this proposal is, however, greatly impaired by Sørensen's utter disregard for the rich philosophical literature existing on the subject: no attempt is made to confront his view with the now standard arguments against theories of that type. Even many inner difficulties of the proposed solution are ignored. E.g., one may ask what values do 't' and 'p' take in the definition of 'Zeus'. Or take the following puzzle: are 'The x that taught Aristotle in p at t' and 'The x that studied with Socrates in p at t' both the meaning of 'Plato'? Sørensen's view that "A national register may be looked upon as a dictionary of proper names" suggests a positive answer, but surely R and S cannot be the same meaning. Many similar problems bother the reader of Sørensen's book, but, unfortunately, they are nowhere discussed.—E. M. Z. (shrink)

To consider power as not only the direct physical oppression of others, but as a production of authority through discursive knowledge and a claimed ‘expertise’ of the world, has been one of Foucault’s great legacies to critical work on mental health and illness. As arbiters of the ‘truth’ on what is and what is not mental pathology, I agree with Swerdfager that the privileged knowledge of the mental health professions and the consequential marginalization of other forms of knowledge on distress (...) can be better theorized through an investigation of the power/knowledge nexus. Practically, scholars and researchers can begin to address these... (shrink)

Rudolf Carnap, remembering in his Autobiography a visit to Warsaw in November 1930, and recalling animated discussions with Lesniewski, Kotarbinski, and Tarski, expressed deep regret that stimulating and fruitful works in the field of logic and theory of knowledge, published only in the Polish language, were inaccessible to the philosophical world. An analogous opinion is expressed by Karl R. Popper who has stated that his methodological solutions were influenced by Alfred Tarski more than by anybody else. Regarding similar appraisals and (...) trying to partially eliminate the mentioned barrier of the language, D. Reidel Publishing Company has edited an anthology of methodological papers published in Poland between 1947-72. The anthology consists of thirty-three articles by twenty Polish logicians investigating the issues of the general methodology of empirical sciences. (shrink)

The complex chaotic dynamics and multistability of financial system are some important problems in micro- and macroeconomic fields. In this paper, we study the influence of two-delay feedback on the nonlinear dynamics behavior of financial system, considering the linear stability of equilibrium point under the condition of single delay and two delays. The system undergoes Hopf bifurcation near the equilibrium point. The stability and bifurcation directions of Hopf bifurcation are studied by using the normal form method and central manifold theory. (...) The theoretical results are verified by numerical simulation. Furthermore, one feature of the proposed financial chaotic system is that its multistability depends extremely on the memristor initial condition and the system parameters. It is shown that the nonlinear dynamics of financial chaotic system can be significantly changed by changing the values of time delays. (shrink)

The complexity of biobank research raises concerns about individuals’ understanding of the information conveyed in the consent process for such research.. We report the results of a qualitative, cognitive interview study with an ethnically, linguistically, and educationally diverse sample of 43 respondents to assess the clarity and utility of a multimedia tool developed for a biobank. Using weighted randomization, respondents were assigned to either view the multimedia tool or read a written consent document . The study illustrates the utility of (...) cognitive interviews for gaining insights from prospective research participants about the clarity of informed consent tools. Findings suggest that a multimedia tool is useful for communicating key messages but should be combined with a written consent document and personal interaction with the study staff. We recommend that the potential value of multimedia tools should be more rigorously tested in a randomized controlled trial. (shrink)

In the rapidly evolving field of wireless power transfer (WPT), achieving systems that combine efficiency with reliability is crucial. This paper presents a simulation-based approach using CST Studio Suite to optimize WPT systems for wireless battery chargers in electric bikes. The study fixes the size of both the transmitter and receiver coils, the spacing between turns, and the number of coil turns, with a set distance of 20mm between the transmitter and receiver coils. CST Studio Suite is employed to determine (...) the parameters of resonance capacitors and the optimal switching frequency to enhance WPT efficiency. This powerful simulation tool allows researchers and engineers to design resonance compensation circuits more effectively, optimizing power transfer efficiency. The simulation conducted with CST Studio Suite confirms its effectiveness in designing a WPT system, achieving an impressive peak efficiency of 99.61% at the resonant frequency. The paper demonstrates CST Studio Suite's capability to accurately predict WPT system performance by developing detailed electromagnetic models and fine-tuning simulation parameters to reflect real operating conditions. Iterative simulations resulted in optimized practices, validated by select results that highlight the method's effectiveness and showcase an optimal balance between system complexity and efficiency. These findings provide a strategic framework for future WPT system development, offering practical guidance for researchers and industry professionals aiming to advance WPT technology. (shrink)

Background The allocation of scarce deceased donor kidneys is a complex process. Transplant providers are increasingly relying on constructs such as frailty and cognitive function to guide kidney transplant (KT) candidate selection. Patient views of the ethical issues surrounding the use of such constructs are unclear. We sought to assess KT candidates’ attitudes and beliefs about the use of frailty and cognitive function to guide waitlist selection.Methods KT candidates were randomly recruited from an ongoing single-center cohort study of frailty and (...) cognitive function. Semi-structured interviews were conducted, and thematic analysis was performed. Inductively derived themes were mapped onto bioethics principles.Results Twenty interviews were conducted (65% contact rate, 100% participation rate) (60% male; 70% White). With respect to the use of frailty and cognitive function in waitlisting decisions, four themes emerged in which participants: (1) valued maximizing a scarce resource (utility); (2) prioritized equal access to all patients (equity); (3) appreciated a proportional approach to the use of equity and utility (precautionary utility); and (4) sought to weigh utility- and equity-based concerns regarding social support. While some participants believed frailty and cognitive function were useful constructs to maximize utility, others believed their use would jeopardize equity. Patients were uncomfortable with using single factors such as frailty or cognitive impairment to deny someone access to transplantation; participants instead encouraged using the constructs to identify opportunities for intervention to improve frailty and cognitive function prior to KT.Conclusions KT candidates’ values mirrored the current allocation strategy, seeking to balance equity and utility in a just manner, albeit with conflicting viewpoints on the appropriate use of frailty and cognitive impairment in waitlisting decisions.

Progressive supranuclear palsy is a movement disorder with prominent tau neuropathology. Brain diseases with abnormal tau deposits are called tauopathies, the most common of which is Alzheimer's disease. Environmental causes of tauopathies include repetitive head trauma associated with some sports. To identify common genetic variation contributing to risk for tauopathies, we carried out a genome-wide association study of 1,114 individuals with PSP and 3,247 controls followed by a second stage in which we genotyped 1,051 cases and 3,560 controls for the (...) stage 1 SNPs that yielded P ≤ 10-3. We found significant previously unidentified signals associated with PSP risk at STX6, EIF2AK3 and MOBP. We confirmed two independent variants in MAPT affecting risk for PSP, one of which influences MAPT brain expression. The genes implicated encode proteins for vesicle-membrane fusion at the Golgi-endosomal interface, for the endoplasmic reticulum unfolded protein response and for a myelin structural component. © 2011 Nature America, Inc.

A fundamental way in which human thought has developed has been constantly to explain the earliest "classics" that are the source of that thought. All in all, the number of such classics is not very high, their explanations are past counting. Moreover, they are constantly increasing, giving rise to an explanatory chain deriving from the classics. In the development of Chinese philosophy, this aspect is particularly noticeable, so that one can describe Chinese philosophy as a continual explanation of the classics. (...) This holds for both Confucianism and Daoism. The main classics of Daoism are the Laozi and the Zhuangzi. These two works have been constantly reread and reinterpreted throughout history. From the late nineteenth century onward, Chinese philosophy came into closer contact with Western philosophy. Foreign concepts were brought in to provide philosophers with new "insight." Some thinkers applied this new insight or these foreign concepts to the Daoist classics. In this way, they brought a new explanation of the Daoist classics and enriched the ways of interpreting the texts.1 Paving the way in this direction were Yan Fu (1853-1921). Zhang Taiyan (1869-1936), Liang Qichao (1873-1929), Wang Guowei (1877-1927), and Hu Shi (1891-1962). (shrink)
