HERMENÊUTICA FILOSÓFICA UMA CONFIGURAÇÃO ENTRE A AMIZADE ARISTOTÉLICA E A DIALÉTICA DIALÓGICA
Authors: Rohden Luiz 
Published: October 2016

Neste artigo pretendemos mostrar, por um lado, alguns aspectos da hermenêutica filosófica desenvolvida por Hans-Georg Gadamer. Optamos aqui pela explicitação do diálogo enquanto o modo mais próprio da hermenêutica efetivar-se. Para tanto, desenvolveremos algumas exigências e condições intrínsecas ao diálogo hermenêutico, o que nos permite reformular e ampliar a concepção hegeliana de dialética sintética. Eis porque a dialética, a partir da hermenêutica gadameriana, passa a ser denominada de dialógica. Por outro lado, mostraremos a proximidade e o vínculo existente entre a hermenêutica e a ética aristotélica no que diz respeito à concepção aristotélica de amizade. Revisitaremos esta concepção com o intuito de mostrar que nela estão reunidos e justificados os principais pressupostos da postura hermenêutica. Além disso, a imbricação entre a dialética dialógica gadameriana e a concepção de amizade em Aristóteles, mostra-se não só fecunda e atual do ponto de vista ético-político, mas necessária para filosofar hoje.Abstract: This article discusses some aspects of the hermeneutical philosophy developed by Hans-Georg Gadamer. The author chose dialogue as the most genuine way for hermeneutics to be put into effect. For that purpose, he develops some demands and intrinsic conditions of the hermeneutical dialogue, which allows him to revise and broaden the Hegelian view of synthetic dialectics. This is why dialectics is called dialogical dialectics on the basis of adamer’s hermeneutics. On the other hand, the article shows the proximity and bond that exists between hermeneutics and Aristotle’s ethics, particularly Aristotle’s view of friendship. It takes anew this view in order to demonstrate that it brings together and justifies the main assumptions of the hermeneutical attitude. Furthermore, the overlapping between Gadamer’s dialogical dialectics and Aristotle’s view of friendship proves to be not only fruitful and up-to-date – when it is understood within an ethical-political project – but also necessary to make philosophy today.
Meaningful Thresholds for the Volume-Outcome Relationship in Total Knee Arthroplasty
Authors: Wilson Sean , Marx Robert G. , Pan Ting-Jung , Lyman Stephen 
Published: October 2016

Background:
Increasing evidence supports the finding that patients undergoing a total knee arthroplasty with high-volume physicians and hospitals achieve better outcomes. Unfortunately, the existing definitions for high-volume surgeons and hospitals are highly variable and entirely arbitrary. The aim of this study was to identify a set of meaningful hospital and surgeon total knee arthroplasty volume thresholds.

Methods:
Using 289,976 patients undergoing primary total knee arthroplasty from an administrative database, we applied stratum-specific likelihood ratio (SSLR) analysis of a receiver operating characteristic (ROC) curve to generate sets of volume thresholds most predictive of adverse outcomes. The outcomes considered for surgeon volume included 90-day complication and 2-year revision. For hospital volume, we considered 90-day complications and 90-day mortality.

Results:
SSLR analysis of the ROC curves for 90-day complication and 2-year revision rates by surgeon volume identified four volume categories: 0 to 12, 13 to 59, 60 to 145, and ≥146 total knee arthroplasties per year. Complication rates decreased significantly (p < 0.05) in progressively higher-volume categories. Revision rates followed a similar pattern, but did not decrease between surgeons performing 60 to 145 arthroplasties per year and those performing ≥146 arthroplasties per year. SSLR analysis of 90-day complication and 90-day mortality rates by hospital volume also identified four volume categories: 0 to 89, 90 to 235, 236 to 644, and ≥645 total knee arthroplasties per year. Complication rates decreased significantly (p < 0.05) in progressively higher-volume categories, but the rates did not decrease between hospitals performing 236 to 644 arthroplasties per year and those performing ≥645 arthroplasties per year. Mortality rates for hospitals with ≥645 total knee arthroplasties per year were significantly lower (p < 0.05) than those below the threshold.

Conclusions:
Our study supports the use of SSLR analysis of ROC curves for risk-based volume stratification in total knee arthroplasty volume-outcomes research. SSLR analysis established meaningful volume definitions for low, medium, high, and very high-volume total knee arthroplasty surgeons and hospitals. This should help patients, surgeons, hospitals, and policymakers to make decisions with regard to the optimal delivery of total knee arthroplasty.

Safety and Outcomes of Inpatient Compared with Outpatient Surgical Procedures for Ankle Fractures
Authors: Qin Charles , Dekker Robert G. , Blough Jordan T. , Kadakia Anish R. 
Published: October 2016

Background:
As the cost of health-care delivery rises in the era of bundled payments for care, there is an impetus toward minimizing hospitalization. Evidence to support the safety of open reduction and internal fixation (ORIF) of ankle fractures in the outpatient setting is largely anecdotal.

Methods:
Patients who underwent ORIF from 2005 to 2013 were identified via postoperative diagnoses of ankle fracture and Current Procedural Terminology codes; patients with open fractures and patients who were emergency cases were excluded. Patients undergoing inpatient and outpatient surgical procedures were propensity score-matched to reduce differences in the baseline characteristics. Primary tracked outcomes included medical and surgical complications, readmission, and reoperation within 30 days of the procedure. Binary logistic regression models were created that determined the risk-adjusted relationship between admission status and primary outcomes.

Results:
Outpatient surgical procedures were associated with lower rates of urinary tract infection (0.4% compared with 0.9%; p = 0.041), pneumonia (0.0% compared with 0.5%; p = 0.002), venous thromboembolic events (0.3% compared with 0.8%; p = 0.049), and bleeding requiring transfusion (0.1% compared with 0.6%; p = 0.012). Outpatient status was independently associated with reduced 30-day medical morbidity (odds ratio, 0.344 [95% confidence interval, 0.201 to 0.589]). No significant differences were uncovered with respect to surgical complications (p = 0.076), unplanned reoperations (p = 0.301), and unplanned readmissions (p = 0.358).

Conclusions:
In patients with closed fractures and minimal comorbidities, outpatient ORIF was associated with reduced risk of select 30-day medical morbidity and no difference in surgical morbidity, reoperations, and readmissions relative to inpatient. Factors unaccounted for when creating matched cohorts may impact our results. Our findings lend reassurance to surgeons who defer admission for low-risk patients.

Tanquam monetam patrie propriam (Clermont, 1282). Une approche des identités monétaires médiévales ?
Authors: Bompaire Marc 
Published: October 2016

La détention de monnaie peut apparaître comme un facteur de différenciation sociale et la frappe de monnaie comme une affirmation de souveraineté politique au Moyen Âge – comme à d’autres époques. En revanche, l’identification des utilisateurs à leur pays ou à la foi chrétienne ne paraît guère s’être faite par l’intermédiaire de la monnaie. Celle-ci semble susciter davantage l’attachement à l’échelle de la petite patrie dans un cadre coutumier mais sans véritable
passion.
Une trouvaille d’argentei de la première Tétrarchie provenant du Proche-Orient
Authors: Gautier Georges 
Published: October 2016

For the first time a hoard of tetrarchic argentei from the Near East is here studied as a whole. Consisting of 230 official coins and a contemporary imitation, the hoard is mostly made up of argentei struck at Nicomedia and Antioch, including several unpublished specimens. On this basis, the author attempts to reconstruct the sequence of the silver coinage of these two mints, in particular that of Nicomedia. The hoard covers approximately a five-year period, from 294 until 298 A. D. It obviously contains portions of donativa, possibly received by a member of Galerius’s army after the successful campaign against the Sassanians. The hoard also contains
the first imitation of a tetrarchic silver coin produced in the eastern part of the Empire.
Effects of plant intraspecific diversity across three trophic levels: Underlying mechanisms and plant traits

Published: October 2016

PREMISE OF STUDY:Although there is increasing recognition of the effects of plant intraspecific diversity on consumers, the mechanisms by which such effects cascade‐up to higher trophic levels remain elusive.METHODS:We evaluated the effects of plant (lima bean,Phaseolus lunatus) intraspecific diversity on a suite of insect herbivores (leaf‐chewers, aphids, and seed‐eating beetles) and their third trophic‐level associates (parasitoids and aphid‐tending ants). We established plots of three plants, classified as monocultures of one population source or polycultures with mixtures of three of the four population sources (N = 16 plots per level of diversity). Within each plot, plants were individually placed in pots and canopy contact was prevented, therefore eliminating diversity effects on consumers arising from changes in plant traits due to plant physical interactions.KEY RESULTS:Plant diversity reduced damage by leaf‐chewers as well as aphid abundance, and the latter effect in turn reduced ant abundance. In contrast, plant diversity increased the abundance of seed‐eating beetles, but did not influence their associated parasitoids. There were no effects of diversity on seed traits potentially associated with seed predation, suggesting that differences in early season herbivory between monocultures and polycultures (a likely mechanism of diversity effects on plants since plant interactions were prevented) did not drive concomitant changes in plant traits.CONCLUSIONS:This study emphasizes that effects of plant intraspecific diversity on consumers are contingent upon differences in associate responses within and among higher trophic levels and suggests possible mechanisms by which such effects propagate up this food web.
ON THE INFERENCE OF THE COSMIC-RAY IONIZATION RATE ζ FROM THE HCO+-to-DCO+ ABUNDANCE RATIO: THE EFFECT OF NUCLEAR SPIN
Authors: Shingledecker Christopher N. , Bergner Jennifer B. , Le Gal Romane , Öberg Karin I. , Hincelin Ugo , Herbst Eric 
Published: October 2016

ABSTRACT
The chemistry of dense interstellar regions was analyzed using a time-dependent gas–grain astrochemical simulation and a new chemical network that incorporates deuterated chemistry, taking into account nuclear spin states for the hydrogen chemistry and its deuterated isotopologues. With this new network, the utility of the [HCO+]/[DCO+] abundance ratio as a probe of the cosmic-ray ionization rate has been re-examined, with special attention paid to the effect of the initial value of the ortho-to-para ratio (OPR) of molecular hydrogen. After discussing the use of the probe for cold cores, we compare our results with previous theoretical and observational results for a molecular cloud close to the supernova remnant W51C, which is thought to have an enhanced cosmic-ray ionization rate ζ caused by the nearby γ-ray source. In addition, we attempt to use our approach to estimate the cosmic-ray ionization rate for L1174, a dense core with an embedded star. Beyond the previously known sensitivity of [HCO+]/[DCO+] to ζ, we demonstrate its additional dependence on the initial OPR and, secondarily, on the age of the source, its temperature, and its density. We conclude that the usefulness of the [HCO+]/[DCO+] abundance ratio in constraining the cosmic-ray ionization rate in dense regions increases with the age of the source and the ionization rate as the ratio becomes far less sensitive to the initial value of the OPR.
SEMI-EMPIRICAL MODELING OF THE PHOTOSPHERE, CHROMOPSHERE, TRANSITION REGION, AND CORONA OF THE M-DWARF HOST STAR GJ 832*

ABSTRACT
Stellar radiation from X-rays to the visible provides the energy that controls the photochemistry and mass loss from exoplanet atmospheres. The important extreme ultraviolet (EUV) region (10–91.2 nm) is inaccessible and should be computed from a reliable stellar model. It is essential to understand the formation regions and physical processes responsible for the various stellar emission features to predict how the spectral energy distribution varies with age and activity levels. We compute a state-of-the-art semi-empirical atmospheric model and the emergent high-resolution synthetic spectrum of the moderately active M2 V star GJ 832 as the first of a series of models for stars with different activity levels. We construct a one-dimensional simple model for the physical structure of the star’s chromosphere, chromosphere-corona transition region, and corona using non-LTE radiative transfer techniques and many molecular lines. The synthesized spectrum for this model fits the continuum and lines across the UV-to-optical spectrum. Particular emphasis is given to the emission lines at wavelengths that are shorter than 300 nm observed with the Hubble Space Telescope, which have important effects on the photochemistry of the exoplanet atmospheres. The FUV line ratios indicate that the transition region of GJ 832 is more biased to hotter material than that of the quiet Sun. The excellent agreement of our computed EUV luminosity with that obtained by two other techniques indicates that our model predicts reliable EUV emission from GJ 832. We find that the unobserved EUV flux of GJ 832, which heats the outer atmospheres of exoplanets and drives their mass loss, is comparable to the active Sun.
CONSTRAINING THE PROPERTIES OF DARK MATTER WITH OBSERVATIONS OF THE COSMIC MICROWAVE BACKGROUND
Authors: Thomas Daniel B. , Kopp Michael , Skordis Constantinos 
Published: October 2016

ABSTRACT
We examine how the properties of dark matter, parameterized by an equation-of-state parameter w and two perturbative generalized dark matter (GDM) parameters, c
2

s
(the sound speed) and

(the viscosity), are constrained by existing cosmological data, particularly the Planck 2015 data release. We find that the GDM parameters are consistent with zero, and are strongly constrained, showing no evidence for extending the model of dark matter beyond the cold dark matter (CDM) paradigm. The equation of state of dark matter is constrained to be within

at the 99.7% confidence level (CL), which is several times stronger than constraints found previously using WMAP data. The parameters c
2

s
and

are constrained to be less than

and 6.06 × 10−6 respectively at the 99.7% CL. The inclusion of the GDM parameters does significantly affect the error bars on several ΛCDM parameters, notably the dimensionless dark matter density ω

g
and the derived parameters σ
8 and H
0. This can be partially alleviated with the inclusion of data constraining the expansion history of the universe.

ABSTRACT
We observed the Oort cloud comet C/2014 Q2 (Lovejoy) on 2015 January 31 and February 1 and 2 at a heliocentric distance of 1.3 au and geocentric distance of 0.8 au during its approach to the Sun. Comet Lovejoy was observed with GIANO, the near-infrared high-resolution spectrograph mounted at the Nasmyth-A focus of the TNG (Telescopio Nazionale Galileo) telescope in La Palma, Canary Islands, Spain. We detected strong emissions of radical CN and water, along with many emission features of unidentified origin, across the 1–2.5 μm region. Spectral lines from eight ro-vibrational bands of H2O were detected, six of them for the first time. We quantified the water production rate [Q(H2O), (3.11 ± 0.14) × 1029 s−1] by comparing the calibrated line fluxes with the Goddard full non-resonance cascade fluorescence model for H2O. The production rates of ortho-water [Q(H2O)ORTHO, (2.33 ± 0.11) × 1029 s−1] and para-water [Q(H2O)PARA, (0.87 ± 0.21) × 1029 s−1] provide a measure of the ortho-to-para ratio (2.70 ± 0.76)). The confidence limits are not small enough to provide a critical test of the nuclear spin temperature.
CARBON-TO-OXYGEN RATIOS IN M DWARFS AND SOLAR-TYPE STARS
Authors: Nakajima Tadashi , Sorahana Satoko 
Published: October 2016

ABSTRACT
It has been suggested that high C/O ratios (>0.8) in circumstellar disks lead to the formation of carbon-dominated planets. Based on the expectation that elemental abundances in the stellar photospheres give the initial abundances in the circumstellar disks, the frequency distributions of C/O ratios of solar-type stars have been obtained by several groups. The results of these investigations are mixed. Some find C/O > 0.8 in more than 20% of stars, and C/O > 1.0 in more than 6%. Others find C/O > 0.8 in none of the sample stars. These works on solar-type stars are all differential abundance analyses with respect to the Sun and depend on the adopted C/O ratio in the Sun. Recently, a method of molecular line spectroscopy of M dwarfs, in which carbon and oxygen abundances are derived respectively from CO and H2O lines in the K band, has been developed. The resolution of the K-band spectrum is 20,000. Carbon and oxygen abundances of 46 M dwarfs have been obtained by this nondifferential abundance analysis. Carbon-to-oxygen ratios in M dwarfs derived by this method are more robust than those in solar-type stars derived from neutral carbon and oxygen lines in the visible spectra because of the difficulty in the treatment of oxygen lines. We have compared the frequency distribution of C/O distributions in M dwarfs with those of solar-type stars and have found that the low frequency of high-C/O ratios is preferred.
FERMI-LAT OBSERVATIONS OF THE 2014 MAY–JULY OUTBURST FROM 3C 454.3

Published: October 2016

ABSTRACT
A prominent outburst of the flat spectrum radio quasar 3C 454.3 was observed in 2014 June with the Fermi Large Area Telescope. This outburst was characterized by a three-stage light-curve pattern—plateau, flare, and post-flare—that occurred from 2014 May to July, in a similar pattern as observed during the exceptional outburst in 2010 November. The highest flux of the outburst reported in this paper occurred during 2014 June 7–29, showing a multiple-peak structure in the light-curves. The average flux in these 22 days was found to be

ph cm−2 s−1, with a spectral index, for a simple power law, of

. That made this outburst the first γ-ray high state of 3C 454.3 ever to be detected by Fermi with such a hard spectrum over several days. The highest flux was recorded on 2014 June 15, in a 3 hr bin, at MJD 56823.5625, at a level of

ph cm−2 s−1. The rise time of one of the short subflares was found to be

s at MJD = 56827, when the flux increased from 4 to 12 × 10−6 ph cm−2 s−1. Several photons above 20 GeV were collected during this outburst, including one at 45 GeV on MJD 56827, constraining the γ-ray emission region to be located close to the outer boundary of the broad-line region, leading to fast flux variability.
De la difficulté à « faire parti » dans la Tunisie post-Ben Ali
Authors: Geisser Vincent , Perez Déborah 
Published: October 2016

Aux lendemains de la fuite de Ben Ali, la renaissance du pluripartisme en Tunisie s’inscrit dans une double logique. D’une part, elle consacre le retour sur le devant de la scène politique tunisienne de forces politiques anciennes, issues pour la plupart de la « résistance » au régime autoritaire (islamistes, gauchistes, forces libérales et socio-démocrates) qui profitent du nouveau contexte de libéralisation pour s’organiser matériellement, remobiliser leurs militants et partir à la conquête de leurs électorats. D’autre part, elle se traduit par l’émergence de nouveaux modes d’expression politique qui, tantôt empruntent la forme partisane ordinaire, tantôt cherchent à s’en éloigner pour mieux signifier leur désir de rupture avec l’ancien régime, le stigmate partisan étant lié notamment au traumatisme du parti unique. Dans cet article, il ne s’agit pas de nier la centralité du rôle des partis dans la période post-dictature mais de déplacer le regard au-delà de l’espace partisan, afin de dévoiler les enjeux latents qui sont cristallisés par les conflits politiques et les rapports de force.
Syrie : Une vie politique à inventer sous les bombes
Authors: Kawakibi Salam 
Published: October 2016

Salam Kawakibi revient sur l’alternance de séquences brèves de pluralisme politique et de diverses formes de domination autoritaire qui ont marqué la constitution de la vie politique syrienne, avant de décrire la paralysie politique sous l’effet du régime « sécuritocratique » d’Hafez al-Assad. De là, il dresse le constat amer des obstacles qui se sont dressés devant la génération révolutionnaire pour faire émerger sa direction politique et les conséquences de la militarisation du conflit sur le type de forces politiques et sur la société civile naissante.
« Un parti, ça participe ! » Retour sur le repositionnement du Front des forces socialistes algérien (2011-2012)
Authors: Baamara Layla 
Published: October 2016

À travers le cas du Front des forces socialistes algérien, cet article s’interroge sur les processus de recomposition qui peuvent affecter un parti d’opposition en situation de contrainte. Fin 2011, la question de la participation aux élections législatives – boycottées depuis deux scrutins – est réinscrite à l’ordre du jour après un renouvellement de l’équipe dirigeante. Il ne s’agit pas de considérer que, jusque 2011, le FFS n’a pas connu de recomposition, mais d’analyser comment se redéfinit concrètement, entre 2011 et 2012, sa polarisation autour des espaces, des règles et des enjeux de la politique institutionnelle. Plutôt que de chercher à déterminer si le parti participe ou non à la reproduction du pouvoir autoritaire, nous proposons d’éclairer ce qui se joue en interne et de souligner que ce repositionnement est l’enjeu et le produit de luttes qui donnent lieu à des adaptations et des contestations.

L’épreuve projective intitulée « spatiographie projective familiale » a pour objectif de comprendre l’image inconsciente du corps familial à travers l’analyse du dessin groupal de la « maison de rêve ». Par cette méthodologie, les auteurs peuvent établir un diagnostic de la structure des liens inconscients de la famille et en faire un objet médiateur pour la prise en charge psychothérapique et une épreuve projective groupale familiale pour le diagnostic. Le dessin de la « maison de rêve » est un outil original qui investigue les dimensions diachronique et synchronique permettant une approche complète de la structuration de l’image du corps familial.
