© 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)

Merab Konstantinovich [Mamardashvili] met with me immediately, as soon as I requested it, although he forewarned me that he could only dimly remember much of that distant past in which I was most interested. But evidently that past still perturbed him as well, since he agreed to speak with me even though he had not yet completely recovered from his illness, and hence his voice was feeble, at times subsiding to a whisper; he would pronounce his words indistinctly, constantly sticking (...) one onto another; on top of that, for technical reasons the dictaphone was situated a bit away from him. It was therefore very difficult to transcribe the text, and I raised many questions with the idea of asking Merab Konstantinovich about them at our next meeting and clearing up some things. But alas, there was no next meeting … Hence I am permitting myself now to publish only some of the most clearly enunciated fragments of my conversation with him, one of the four "forefathers" of the Moscow Methodological Circle, whose name for us, today's participants (and hence neophytes) in the methodological movement, is enveloped by legends handed down by word of mouth. I kept my questions to a minimum. Mamardashvili's reminiscences, arguments, and reflections will seem contentious to many. But no matter, one can dispute points of substance even with those who have passed on. (shrink)

The role of nursing faculty members in charge of ethics education is important. Although all nursing students receive the same bioethics education, their experiences differ, related to ethical qualification, which depends on the personal socialization process. This Korean study aimed to provide nursing faculty members with the basic data to help them develop as bioethics experts and provide nursing students with knowledge to improve their ethical decision-making abilities. We used a survey design to assess recognition of bioethical issues and ethical (...) qualification in nursing students and faculty members. A total of 1225 undergraduate students and 140 faculty members participated in this study. The results revealed that nursing students and nursing faculty members generally understood the seriousness of various bioethical issues and both considered the most serious issue to concern abortion. Ethical behavior can be improved by education, and accordingly, nursing ethics should be a mandatory subject, rather than an elective one. (shrink)

Background One of the objectives of medicine is to relieve patients' suffering. As a consequence, it is important to understand patients' perspectives of suffering and their ability to cope. However, there is poor insight into what determines their suffering and their ability to bear it. Purpose To explore the constituent elements of suffering of patients who explicitly request euthanasia or physician-assisted suicide (EAS) and to better understand unbearable suffering from the patients' perspective. Patients and methods A qualitative study using in-depth (...) face-to-face interviews was conducted with 31 patients who had requested EAS. The grounded theory approach was used to analyse the data. Results Medical, psycho-emotional, socio-environmental and existential themes contributed to suffering. Especially fatigue, pain, decline, negative feelings, loss of self, fear of future suffering, dependency, loss of autonomy, being worn out, being a burden, loneliness, loss of all that makes life worth living, hopelessness, pointlessness and being tired of living were constituent elements of unbearable suffering. Only patients with a psychiatric (co)diagnosis suffered unbearably all the time. Conclusions Unbearable suffering is the outcome of an intensive process that originates in the symptoms of illness and/or ageing. According to patients, hopelessness is an essential element of unbearable suffering. Medical and social elements may cause suffering, but especially when accompanied by psycho-emotional and existential problems suffering will become ‘unbearable’. Personality characteristics and biographical aspects greatly influence the burden of suffering. Unbearable suffering can only be understood in the continuum of the patients' perspectives of the past, the present and expectations of the future. (shrink)

Are values and social priorities universal, or do they vary across geography, culture, and time? This question is very relevant to Asia’s emerging economies that are increasingly looking at Western models for answers to their own outmoded health care systems that are in dire need of reform. But is it safe for them to do so without sufficient regard to their own social, political, and philosophical moorings? This article argues that historical and cultural legacies influence prevailing social values with regard (...) to health care financing and resource allocation, and that the Confucian dimension provides a helpful entry point for a deeper understanding of ongoing health care reforms in East Asia – as exemplified by the unique case of Singapore.

This paper inquires into the nature of intertheoretic relations between psychology and neuroscience. This relationship has been characterized by some as one in which psychological explanations eventually will fall away as otiose, overthrown completely by neurobiological ones. Against this view it will be argued that it squares poorly with scientific practices and empirical developments in the cognitive neurosciences. We analyse a case from research on visual perception, which suggests a much more subtle and complex interplay between psychology and neuroscience than (...) a complete take-over of the former by the latter. In the case of vision, cross-theory influences between psychology and neuroscience go back and forth, resulting in refinement in both disciplines. We interpret this case study as showing that: (1) Mutual co-evolution of psychological and neurobiological theories, exemplifying persisting top-down influences from psychology, is a more empirically adequate way to describe psychoneural theory relations than a view on co-evolution, favoured by reductionists, which regards the cross-theory contributions from psychology as merely heuristically useful with no enduring influence on neurobiological theorizing; (2) In research on vision, discovering (or hypothesizing) the neural basis of functions vindicates psychological approaches, it does not eliminate them; (3) Current work on vision shows that many perceptual phenomena must be understood in terms of dynamical interactions between an observer and his/her environment. Therefore, we argue that internalist characterizations of the visual system must be supplemented with externalist accounts that address these reciprocal observer-environment interactions involved in vision. Such processes seem quite different from (internal) cellular and molecular ones, and as such seem to lie outside the scope of neuroscientific inquiry. We conclude that psychoneural reduction or elimination is implausible as a meta-theoretical prediction of theory choice in empirical work. Instead, this case study of vision shows that both psychology and neuroscience contribute to, and complement one another in the study of visual perception. (shrink)

Judgment aggregation theory, which concerns the translation of individual judgments on logical propositions into consistent group judgments, has shown that group consistency generally cannot be guaranteed if each proposition is treated independently from the others. Developing the right method of abandoning independence is thus a high-priority goal. However, little work has been done in this area outside of a few simple approaches. To fill the gap, we compare four methods based on distance metrics between judgment sets. The methods generalize the (...) premise-based and sequential priority approaches to judgment aggregation, as well as distance-based preference aggregation. They each guarantee group consistency and implement a range of distinct functions with different properties, broadening the available tools for social choice. A central result is that only one of these methods (not previously considered in the literature) satisfies three attractive properties for all reasonable metrics. (shrink)

Hegel raises many real problems on the basis of the phenomenology of spirit: logico-ontological, gnoseological, and philosophico-historical problems. But in all spheres, levels, and forms of consciousness, Hegel investigates particularly the formation of the socially developed and historically oriented universal subject of thought, will, and action in the context of the forms of the manifest spirit, forms that in reality assume the status of being. It is precisely this investigation that constitutes the real problematic of Hegel's Phenomenology of Spirit.

Rapidly changing estimates on the Soviet régime''s ability to survive show how difficult it is for American Sovietologists to grasp what is going on.

Corporate social responsibility (CSR) is increasingly becoming a popular business concept in developed economies. As typical of other business concepts, it is on its way to globalization through practices and structures of the globalized capitalist world order, typified in Multinational Corporations (MNCs). However, CSR often sits uncomfortably in this capitalist world order, as MNCs are often challenged by the global reach of their supply chains and the possible irresponsible practices inherent along these chains. The possibility of irresponsible practices puts global (...) firms under pressure to protect their brands even if it means assuming responsibilities for the practices of their suppliers. Pressure groups understand this burden on firms and try to take advantage of the situation. This article seeks to challenge the often taken-for-granted-assumption that firms should be accountable for the practices of their suppliers by espousing the moral (and sometimes legal) underpinnings of the concept of responsibility. Except where corporate control and or corporate grouping exist, it identifies the use of power as a critical factor to be considered in allocating responsibility in firm-supplier relationship; and suggests that the more powerful in this relationship has a responsibility to exert some moral influence on the weaker party. The article highlights the use of code of conducts, corporate culture, anti-pressure group campaigns, personnel training and value reorientation as possible sources of wielding positive moral influence along supply chains.

The notion of a Sasaki projectionon an orthomodular lattice is generalized to a mapping Φ: E × E → E, where E is an effect algebra. If E is lattice ordered and Φ is symmetric, then E is called a Φ-symmetric effect algebra.This paper launches a study of such effect algebras. In particular, it is shown that every interval effect algebra with a lattice-ordered ambient group is Φ-symmetric, and its group is the one constructed by Ravindran in his proof that (...) every effect algebra that has the Riesz decomposition property is an interval algebra. It is shown that the doubling construction introduced in the paper is connected to the conditional event algebrasof Goodman, Nguyen, and Walker. (shrink)

I should like to begin with an observation of a biographical character. I hope this will facilitate discussion of the exceedingly complex task set for me here, the attempt to unify the theory of consciousness with my relationship to philosophy, that is, with what I think about it and what it means to me.

In the article three tragedies: ‘The Battle of Arminius‘ by Christian Dietrich Grabbe, ‘Nibelungs‘ by Friedrich Hebbel, ‘The Ring of the Nibelung‘ by Richard Wagner are considered. The aim of this paper is to investigate how history reception and mythological material correlates with the idea of national identity. The comparative-historical, typological and historical-genetic methods are applied in this publication. The genres of historical, philosophical and mythological tragedy became the most popular genres in the socio-political conditions in the 30s of the (...) 19th century in Germany. Grabbe underlines the idea of the presence of the ‘local‘ regional history within the framework of the ‘big‘ and significant one. Grabbe paid attention to the historical process and historical figures, not to any particular historical event. In his last work, tragedy ‘The Battle of Arminius‘, Grabbe showed his understanding of the country’s historical origins and the creation of a national myth. F. Hebbel and R. Wagner comprehend the images and motifs of Norse mythology as a universal model of human existence. While interpreting the story of Nibelungs, F. Hebbel notes not only its national roots but its universal source; he models the image of the world through the prism of the microcosm of Burgundians/Nibelungs. Wagner’s tetralogy is not so much an interpretation as a creation of the ‘new myth‘. The images of Arminius and Siegfried have the features of the archaic primal forefather, ‘cultural hero‘ of the nation, who intimately related with Nature and home ground. Myth and mythological history are not only the tools of attainment of national identity but the means of reversion the modern man to the lost harmony of the Universe, which pertains to the mythological mind.

The article examines the algorithms for JPEG and JPEG-2000 compression of various graphic images. The main steps of the operation of both algorithms are given, their advantages and disadvantages are noted. The main differences between JPEG and JPEG-2000 are analyzed. It is noted that the JPEG-2000 algorithm allows re-moving visually unpleasant effects. This makes it possible to highlight important areas of the image and improve the quality of their compression. The features of each step of the algorithms are considered and (...) the difficulties of their implementation are compared. The effectiveness of each algorithm is demonstrated by the example of a full-color image of the BSU emblem. The obtained compression ratios were obtained and shown in the corresponding tables using both algorithms. Compression ratios are obtained for a wide range of quality values from 1 to ten. We studied various types of images: black and white, business graphics, indexed and full color. A modified LZW-Lempel-Ziv-Welch algorithm is presented, which is applicable to compress a variety of information from text to images. The modification is based on limiting the graphic file to 256 colors. This made it possible to index the color with one byte instead of three. The efficiency of this modification grows with increasing image sizes. The modified LZW-algorithm can be adapted to any image from single-color to full-color. The prepared tests were indexed to the required number of colors in the images using the FastStone Image Viewer program. For each image, seven copies were obtained, containing 4, 8, 16, 32, 64, 128 and 256 colors, respectively. Testing results showed that the modified version of the LZW algorithm allows for an average of twice the compression ratio. However, in a class of full-color images, both algorithms showed the same results. The developed modification of the LZW algorithm can be successfully applied in the field of site design, especially in the case of so-called flat design. The comparative characteristics of the basic and modified methods are presented. (shrink)

Background: Hospital nurses are frequently the first care givers to receive a patient’s request for euthanasia or physician-assisted suicide (PAS). In France, there is no consensus over which medical practices should be considered euthanasia, and this lack of consensus blurred the debate about euthanasia and PAS legalisation. This study aimed to investigate French hospital nurses’ opinions towards both legalisations, including personal conceptions of euthanasia and working conditions and organisation. Methods: A phone survey conducted among a random national sample of 1502 (...) French hospital nurses. We studied factors associated with opinions towards euthanasia and PAS, including contextual factors related to hospital units with random-effects logistic models. Results: Overall, 48% of nurses supported legalisation of euthanasia and 29%, of PAS. Religiosity, training in pallative care/pain management and feeling competent in end-of-life care were negatively correlated with support for legalisation of both euthanasia and PAS, while nurses working at night were more prone to support legalisation of both. The support for legalisation of euthanasia and PAS was also weaker in pain treatment/palliative care and intensive care units, and it was stronger in units not benefiting from interventions of charity/religious workers and in units with more nurses. Conclusions: Many French hospital nurses uphold the legalisation of euthanasia and PAS, but these nurses may be the least likely to perform what proponents of legalisation call “good” euthanasia. Improving professional knowledge of palliative care could improve the management of end-of-life situations and help to clarify the debate over euthanasia. (shrink)

The concept of evolvability—the capacity of a population to produce and maintain evolutionarily relevant variation—has become increasingly prominent in evolutionary biology. Paleontology has a long history of investigating questions of evolvability, but paleontological thinking has tended to neglect recent discussions, because many tools used in the current evolvability literature are challenging to apply to the fossil record. The fundamental difficulty is how to disentangle whether the causes of evolutionary patterns arise from variational properties of traits or lineages rather than being (...) due to selection and ecological success. Despite these obstacles, the fossil record offers unique and growing sources of data that capture evolutionary patterns of sustained duration and significance otherwise inaccessible to evolutionary biologists. Additionally, there exist a variety of strategic possibilities for combining prominent neontological approaches to evolvability with those from paleontology. We illustrate three of these possibilities with quantitative genetics, evolutionary developmental biology, and phylogenetic models of macroevolution. In conclusion, we provide a methodological schema that focuses on the conceptualization, measurement, and testing of hypotheses to motivate and provide guidance for future empirical and theoretical studies of evolvability in the fossil record.
