We present a one per cent measurement of the cosmic distance scale from the detections of the baryon acoustic oscillations in the clustering of galaxies from the Baryon Oscillation Spectroscopic Survey, which is part of the Sloan Digital Sky Survey III. Our results come from the Data Release 11 sample, containing nearly one million galaxies and covering approximately 8500 square degrees and the redshift range 0.2 < z < 0.7. We also compare these results with those from the publicly released (...) DR9 and DR10 samples. Assuming a concordance Λ cold dark matter cosmological model, the DR11 sample covers a volume of 13 Gpc3 and is the largest region of the Universe ever surveyed at this density. We measure the correlation function and power spectrum, including density-field reconstruction of the BAO feature. The acoustic features are detected at a significance of over 7σ in both the correlation function and power spectrum. Fitting for the position of the acoustic features measures the distance relative to the sound horizon at the drag epoch, rd, which has a value of rd,fid = 149.28 Mpc in our fiducial cosmology. We find DV = at z = 0.32 and DV = at z = 0.57. At 1.0 per cent, this latter measure is the most precise distance constraint ever obtained from a galaxy survey. Separating the clustering along and transverse to the line of sight yields measurements at z = 0.57 of DA = and H =. Our measurements of the distance scale are in good agreement with previous BAO measurements and with the predictions from cosmic microwave background data for a spatially flat CDM model with a cosmological constant. © 2014 The Author Published by Oxford University Press on behalf of the Royal Astronomical Society.

The purpose of this valuable book is to consider recent cultural trends in bioethics from a Catholic perspective. Bioethics is intended for a lay audience interested in understanding bioethical issues from a Catholic perspective.

BackgroundAlthough the number of reporting guidelines has grown rapidly, few have gone through an updating process. The STARD statement (Standards for Reporting Diagnostic Accuracy), published in 2003 to help improve the transparency and completeness of reporting of diagnostic accuracy studies, was recently updated in a systematic way. Here, we describe the steps taken and a justification for the changes made.ResultsA 4-member Project Team coordinated the updating process; a 14-member Steering Committee was regularly solicited by the Project Team when making critical (...) decisions. First, a review of the literature was performed to identify topics and items potentially relevant to the STARD updating process. After this, the 85 members of the STARD Group were invited to participate in two online surveys to identify items that needed to be modified, removed from, or added to the STARD checklist. Based on the results of the literature review process, 33 items were presented to the STARD Group in the online survey: 25 original items and 8 new items; 73 STARD Group members (86 %) completed the first survey, and 79 STARD Group members (93 %) completed the second survey.Then, an in-person consensus meeting was organized among the members of the Project Team and Steering Committee to develop a consensual draft version of STARD 2015. This version was piloted in three rounds among a total of 32 expert and non-expert users. Piloting mostly led to rewording of items. After this, the update was finalized. The updated STARD 2015 list now consists of 30 items. Compared to the previous version of STARD, three original items were each converted into two new items, four original items were incorporated into other items, and seven new items were added.ConclusionsAfter a systematic updating process, STARD 2015 provides an updated list of 30 essential items for reporting diagnostic accuracy studies.

Prior research has demonstrated that antisocial behavior, substance-use disorders, and personality dimensions of aggression and impulsivity are indicators of a highly heritable underlying dimension of risk, labeled externalizing. Other work has shown that individual trait constructs within this psychopathology spectrum are associated with reduced self-monitoring, as reflected by amplitude of the error-related negativity (ERN) brain response. In this study of undergraduate subjects, reduced ERN amplitude was associated with higher scores on a self-report measure of the broad externalizing construct that links (...) these various indicators. In addition, the ERN was associated with a response-locked increase in anterior theta (4–7 Hz) oscillation; like the ERN, this theta response to errors was reduced among high-externalizing individuals. These findings suggest that neurobiologically based deficits in endogenous action monitoring may underlie generalized risk for an array of impulse-control problems. (shrink)

This study investigates how reality television viewing is linked to Facebook. Utilizing a survey of 736 students in a school of journalism at a large Midwestern university, researchers examined whether viewers of different genres of reality television were more prone to problematic information sharing on Facebook. The study found that all viewers of reality were prone to problematic information sharing. However, viewers of drama-, competition-, and crime-based shows were most likely to share problematic information. These results are interpreted using social (...) cognitive theory. (shrink)

Psychiatry is rapidly adopting digital phenotyping and artificial intelligence/machine learning tools to study mental illness based on tracking participants’ locations, online activity, phone and text message usage, heart rate, sleep, physical activity, and more. Existing ethical frameworks for return of individual research results (IRRs) are inadequate to guide researchers for when, if, and how to return this unprecedented number of potentially sensitive results about each participant’s real-world behavior. To address this gap, we convened an interdisciplinary expert working group, supported by (...) a National Institute of Mental Health grant. Building on established guidelines and the emerging norm of returning results in participant-centered research, we present a novel framework specific to the ethical, legal, and social implications of returning IRRs in digital phenotyping research. Our framework offers researchers, clinicians, and Institutional Review Boards (IRBs) urgently needed guidance, and the principles developed here in the context of psychiatry will be readily adaptable to other therapeutic areas.

The unbridled positivity toward curiosity and creativity may be excessive. Both aid species survival through exploration and advancement. These beneficial effects are well documented. What remains is to understand their optimal levels and contexts for maximal achievement, health, and well-being. Every beneficial element to individuals and groups carries the potential for harm – curiosity and creativity included.

BackgroundThere is increasing need for peer reviewers as the scientific literature grows. Formal education in biostatistics and research methodology during residency training is lacking. In this pilot study, we addressed these issues by evaluating a novel method of teaching residents about biostatistics and research methodology using peer review of standardized manuscripts. We hypothesized that mentored peer review would improve resident knowledge and perception of these concepts more than non-mentored peer review, while improving review quality.MethodsA partially blinded, randomized, controlled multi-center study (...) was performed. Seventy-eight neurology residents from nine US neurology programs were randomized to receive mentoring from a local faculty member or not. Within a year, residents reviewed a baseline manuscript and four subsequent manuscripts, all with introduced errors designed to teach fundamental review concepts. In the mentored group, mentors discussed completed reviews with residents. Primary outcome measure was change in knowledge score between pre- and post-tests, measuring epidemiology and biostatistics knowledge. Secondary outcome measures included level of confidence in the use and interpretation of statistical concepts before and after intervention, and RQI score for baseline and final manuscripts.ResultsSixty-four residents (82%) completed initial review with gradual decline in completion on subsequent reviews. Change in primary outcome, the difference between pre- and post-test knowledge scores, did not differ between mentored (−8.5%) and non-mentored (−13.9%) residents (p = 0.48). Significant differences in secondary outcomes (using 5-point Likert scale, 5 = strongly agree) included mentored residents reporting enhanced understanding of research methodology (3.69 vs 2.61; p = 0.001), understanding of manuscripts (3.73 vs 2.87; p = 0.006), and application of study results to clinical practice (3.65 vs 2.78; p = 0.005) compared to non-mentored residents. There was no difference between groups in level of interest in peer review (3.00 vs 3.09; p = 0.72) or the quality of manuscript review assessed by the Review Quality Instrument (RQI) (3.25 vs 3.06; p = 0.50).ConclusionsWe used mentored peer review of standardized manuscripts to teach biostatistics and research methodology and introduce the peer review process to residents. Though knowledge level did not change, mentored residents had enhanced perception in their abilities to understand research methodology and manuscripts and apply study results to clinical practice.

© 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)

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.

Although the E-Z Reader model accounts well for eye-tracking data, it will be judged by new predictions and consistency with evidence from brain imaging methodologies. The stage architecture proposed for lexical access seems somewhat arbitrary and calculated timings are conservatively slow. There are certain effects in the literature that seem incompatible with the model.

Il s'agit d'un travail consacré à Heidegger en tant que ce dernier s'est donné pour tâche de frayer le chemin menant à une pensée post-métaphysique. C'est cette pensée qui est caractérisée comme "pensée en souffrance" au double sens de pensée à venir, qui n'est pas comme telle programmable et à laquelle il s'agit seulement de se préparer, et de pensée cherchant à répondre à l'attente d'une humanité soumise à la dévastation et en recherche de salut. Françoise Dastur a salué ce (...) texte en ces termes : "Ecrit dans une langue claire et élégante, et s'appuyant sur une lecture informée et approfondie de l'oeuvre entière de Heidegger, à laquelle on sent que l'auteur a consacré de longues années de méditation, cet essai se présente comme une tentative d'appropriation personnelle de sa pensée, et comme une mise en relief de ses axes principaux.".

THE emotive theory of ethics made its first brief and rather tentative appearance in The Meaning of Meaning by Ogden and Richards in 1922. It did not gain currency, however, nor receive anything like a complete formulation until it was adopted by Logical Positivism, and in particular by A J Ayer in Language, Truth and Logic. Ayer’s account was soon superseded by that of Charles L Stevenson, whose views were finally elaborated in Ethics and Language in 1942. This, the classic (...) statement of emotivism, is one of the great works of moral philosophy of this century, worthy to be ranked with the Principia Ethica of G E Moore. (shrink)

Comment penser l’enracinement phénoménologique de l’éthique? La question demande à être posée par le sens même qu’Aristote assignait à cette articulation d’une disposition et d’un caractère qui constitue la dimension éthique de notre être au monde. Sur cette voie l’ouverture proprement phénoménologique est opérée par la cinquième Méditation cartésienne décrivant l’altération originaire dans l’auto-appréhension charnelle et le transfert analogique qu’elle autorise comme l’opération où l’ego découvre l’altérité de l’autre dans l’intercorporéité. Poursuivre au-delà, vers la signifiance éthique de ce transfert, de (...) cette méta-phore, E. Lévinas, comme on sait, s’y est d’abord engagé dans une conférence de 1962 avant d’abandonner ce thème pour une formulation plus radicale de l’injonction venue de l’autre, sans réciprocité. Mais n’était-ce pas renoncer par là même au lien unissant responsabilité et reconnaissance? C’est ce lien au contraire vers lequel l’analyse ricœurienne de la dimension ontologique de la « métaphore vive » ouvre un accès. Il s’agit de décrire la ressource de sens d’un être-comme métaphorique faisant paraître l’articulation de la sollicitude et de l’estime de soi. (shrink)

This article deals with an object of Philosophy, strictly the Philosophy of Language, which concerns the study of the logic and of the dialectics. So, it proposes to analyze the dialectic-logical conceptual aspects in the Corpus Hermeticum 12.12-14a in comparison with the logical texts of the Stoicorum Veterum Fragmenta, in order to find supposed sources conformed with the hermetic text, and know how they were re-worked in it. For that, the references, descriptions and quotations of Sextus Empiricus and of Diocles (...) Magnes, apud Diogenes Laertius, they constitute important sources on the philosophical doctrines of Zenon, Cleanthes and Crysippus. One considers that the doctrine of the first part of the Corp. Herm. 12 is, often, Platonic. Nevertheless, there are realized signs of influences of stoicism. The conception about νοῦς [nous] in the man is from Platonic origin, but the expression προφοριϰὸς λόγος [prophorikos logos] is certainly Stoic. Then, the Corp. Herm. 12 is a product of a middle-stoicism or middle-Platonism, stoicizing Platonism or platonizing Stoicism, which cannot have appeared before the c. I B.C.E. Specifically, the article is interested in the dialectic-logical problem that involve some Stoic concepts, as λόγος, προφοριϰὸς λόγος, φωνή [phōnē], as well as the problem of the connective propositional logic in the platonizing process through the doctrine of νοῦς themed in the Corp. Herm. 12.12-14a, assuming a theological dimension and a divine character of λόγος, by being ἐνδιάϑετος λόγος, the thought that exists ἐν τῇ διαϑέσει, ἐν τῷ νῷ. (shrink)

The concept of innateness is a part of folk wisdom but is also used by biologists and cognitive scientists. This concept has a legitimate role to play in science only if the colloquial usage relates to a coherent body of evidence. We examine many different candidates for the post of scientific successor of the folk concept of innateness. We argue that none of these candidates is entirely satisfactory. Some of the candidates are more interesting and useful than others, but the (...) interesting candidates are not equivalent to each other and the empirical and evidential relations between them are far from clear. Researchers have treated the various scientific notions that capture some aspect of the folk concept of innateness as equivalent to each other or at least as tracking properties that are strongly correlated with each other. But whether these correlations exist is an empirical issue. This empirical issue has not been thoroughly investigated because in the attempt to create a bridge between the folk view and their theories, researchers have often assumed that the properties must somehow cluster. Rather than making further attempts to import the folk concept of innateness into the sciences, efforts should now be made to focus on the empirical questions raised by the debates and pave the way to a better way of studying the development of living organisms. Such empirical questions must be answered before it can be decided whether a good scientific successor – in the form of a concept that refers to a collection of biologically significant properties that tend to co-occur – can be identified or whether the concept of innateness deserves no place in science.
