Published: December 2018

El rendimiento deportivo busca potenciar la función física y psicológica como parte de un deporte determinado, y en él está implícito el índice de motivación personal y familiar para evitar la deserción deportiva y por ende sistematizar el entrenamiento deportivo; por ello, gestionar el proceso de iniciación deportiva implica relacionar variables tales como el rendimiento físico inicial, la deserción deportiva y el vínculo familiar para la toma de acciones estratégicas acertadas. Por ello, el objetivo de la investigación es elaborar un grupo de acciones que permita estimular la iniciación y permanencia de las niñas identificadas como talentos, para la práctica del Atletismo infantil en La Federación Deportiva de Loja. La investigación se enmarca en las características de la descripción, la transversalidad y la correlación. Se estudian a 30 atletas, sexo femenino (8-11 años), y a 56 padres de ellas mediante la técnica de encuesta, aplicando además los test de Estatura, Rapidez (30m), Salto Largo, Abdominales, Planchas y Resistencia (400m). A partir de la descripción de las potencialidades individuales de las atletas, y de los familiares, se diseñaron 13 acciones estratégicas para potenciar la permanencia de las atletas en los entrenamientos, permitiendo mantener la comunicación entre la familia, las niñas, el profesorado y los entrenadores.
SMA Line Observations of the CH3OH-maser Outflow in DR21(OH)

Published: December 2018

Abstract
We present a (sub)millimeter line survey of the methanol maser outflow located in the massive star-forming region DR21(OH) carried out with the Submillimeter Array (SMA) at 217/227 GHz and 337/347 GHz. We find transitions from several molecules toward the maser outflow such as CH3OH, H2CS, C17O, H13CO+, and C34S. However, with the present observations, we cannot discard the possibility that some of the observed species such as C17O, C34S, and H2CS, might be instead associated with the compact and dusty continuum sources located in the MM2 region. Given that most of transitions correspond to methanol lines, we have computed a rotational diagram with CASSIS and an LTE synthetic spectra with XCLASS for the detected methanol lines in order to estimate the rotational temperature and column density in the small solid angle of the outflow where enough lines are present. We obtain a rotational temperature of 28 ± 2.5 K and a column density of 6.0 ± 0.9 × 1015 cm−2. These values are comparable to those column densities/rotational temperatures reported in outflows emanating from low-mass stars. Extreme and moderate physical conditions to excite the maser and thermal emission coexist within the CH3OH flow. Finally, we do not detect any complex molecules associated with the flow, e.g., CH3OCHO, (CH3)2CO, and CH3CH2CN.
Probabilistic Random Forest: A Machine Learning Algorithm for Noisy Data Sets
Authors: Reis Itamar , Baron Dalya , Shahaf Sahar 
Published: December 2018

Abstract
Machine learning (ML) algorithms have become increasingly important in the analysis of astronomical data. However, because most ML algorithms are not designed to take data uncertainties into account, ML-based studies are mostly restricted to data with high signal-to-noise ratios. Astronomical data sets of such high quality are uncommon. In this work, we modify the long-established Random Forest (RF) algorithm to take into account uncertainties in measurements (i.e., features) as well as in assigned classes (i.e., labels). To do so, the Probabilistic Random Forest (PRF) algorithm treats the features and labels as probability distribution functions, rather than deterministic quantities. We perform a variety of experiments where we inject different types of noise into a data set and compare the accuracy of the PRF to that of RF. The PRF outperforms RF in all cases, with a moderate increase in running time. We find an improvement in classification accuracy of up to 10% in the case of noisy features, and up to 30% in the case of noisy labels. The PRF accuracy decreased by less then 5% for a data set with as many as 45% misclassified objects, compared to a clean data set. Apart from improving the prediction accuracy in noisy data sets, the PRF naturally copes with missing values in the data, and outperforms RF when applied to a data set with different noise characteristics in the training and test sets, suggesting that it can be used for transfer learning.
Transport Modeling of Interplanetary Electrons in the 2002 October 20 Solar Particle Event
Authors: Dröge W. , Kartavykh Y. Y. , Wang L. , Telloni D. , Bruno R. 
Published: December 2018

Abstract
We analyze electrons in the energy range 1–180 keV, observed by the Wind spacecraft following an impulsive solar flare on 2002 October 20. The event is characterized by weak, but measurable pitch-angle scattering, which allows a characterization of the pitch-angle scattering coefficient

, as well as by particle reflection at an outer boundary. Based on numerical solutions of the focused transport equation we present fits to the observed electron fluxes, with emphasis on a detailed modeling of the particles’ angular distributions. By means of the wavelet transform method we estimate the slab component of the fluctuation, which is frequently assumed to dominate the particle scattering. We find that the values of

obtained from the modeling for several energy ranges disagree strongly with the ones calculated from the estimated slab component for this event and standard quasi-linear theory, in the pitch-angle dependence of the scattering coefficient and also in its magnitude. These results indicate that in this event the scattering of electrons at low energies is much weaker than predicted by the above models, and that at large wavenumbers the slab component makes up only a few per cent of the fluctuations. We discuss whether in weak-scattering events the concept of pitch-angle diffusion due to a resonant interaction of the particles with the turbulence would have to be reconsidered, and whether additional effects such magnetic mirroring of the electrons and intermittency of the fluctuations would have to be taken into account.
Galaxy Inclination and the IRX–β Relation: Effects on UV Star Formation Rate Measurements at Intermediate to High Redshifts

Abstract
At intermediate and high redshifts, measurements of galaxy star formation rates are usually based on rest-frame ultraviolet (UV) data. A correction for dust attenuation, A
UV, is needed for these measurements. This correction is typically inferred from UV spectral slopes (β) using an equation known as “Meurer’s Relation.” In this paper, we study this relation at a redshift of 1.5 using images and photometric measurements in the rest-frame UV (HST) through mid-infrared (Spitzer). It is shown that massive star-forming galaxies (above

) have dust corrections that are dependent on their inclination to the line of sight. Edge-on galaxies have higher A
UV and infrared excess (IRX = L(IR)/L(UV)) than face-on galaxies at a given β. Interestingly, dust corrections for low-mass star-forming galaxies do not depend on inclination. This is likely because more massive galaxies have more disk-like shapes/kinematics, while low-mass galaxies are more prolate and have more disturbed kinematics. To account for an inclination-dependent dust correction, a modified Meurer’s Relation is derived:

, where b/a is the galaxy axis ratio. This inclination dependence of A
UV can be explained by a two-component model of the dust distribution inside galaxies. In such a model, the dust attenuation of edge-on galaxies has a higher contribution from a mixture component (dust uniformly mixed with stars in the diffuse interstellar medium), and a lower contribution from a birth cloud component (near-spherical dust shells surrounding young stars in H ii regions) than that of face-on galaxies. The difference is caused by the larger path lengths through disks at higher inclinations.

Published: December 2018

Abstract
The HST Treasury Program Advanced Spectral Library Project: Cool Stars was designed to collect representative, high-quality UV spectra of eight evolved F−M type cool stars. The Space Telescope Imaging Spectrograph (STIS) echelle spectra of these objects enable investigations of a broad range of topics, including stellar and interstellar astrophysics. This paper provides a guide to the spectra of the two evolved M stars, the M2 Iab supergiant α Ori and the M3.4 giant γ Cru, with comparisons to the prototypical K1.5 giant α Boo. It includes identifications of the significant atomic and molecular emission and absorption features and discusses the character of the photospheric and chromospheric continua and line spectra. The fluorescent processes responsible for a large portion of the emission-line spectrum, the characteristics of the stellar winds, and the available diagnostics for hot and cool plasmas are also summarized. This analysis will facilitate the future study of the spectra, outer atmospheres, and winds, not only of these objects but of numerous other cool, low-gravity stars, for years to come.
Normes sociales de genre et inégalité professionnelle : quelle influence du sentiment de culpabilité des femmes ?
Authors: Poilpot-Rocaboy Gwénaëlle , Berthe Bénédicte , Chan Christopher 
Published: December 2018

Notre étude analyse l’influence des normes sociales de genre et notamment l’attente sociale d’être une « bonne mère » et une « bonne ménagère » sur l’inégalité professionnelle entre les femmes et les hommes. Nous appuyant sur la littérature, nous présentons un modèle qui teste les liens entre les normes sociales de genre associées aux domaines familial et domestique, le sentiment de culpabilité des femmes et la régulation de leurs comportements au travail (baisse du temps de travail, refus d’une promotion, refus d’une mobilité géographique favorable pour la carrière, limitation des ambitions professionnelles). Une méthodologie quantitative et l’analyse de 326 questionnaires de femmes actives révèlent que si les normes sociales de « bonne mère » et de « bonne ménagère » n’ont pas d’effets directs sur les comportements des femmes au travail, elles les impactent indirectement via le sentiment de culpabilité qu’elles génèrent. Ainsi, le rôle médiateur du sentiment de culpabilité dans la relation entre les normes sociales féminines liées aux domaines familial et domestique et la régulation de leurs comportements relatifs à leurs choix de carrière est ici révélé.
L’engagement durable des parties prenantes dans une démarche de GRH territoriale : le cas de la GTEC de Sophia Antipolis
Authors: Loufrani-Fedida Sabrina , Saint-Germes Ève 
Published: December 2018

L’objectif de cet article est de mieux comprendre comment se construit l’engagement durable des parties prenantes dans une démarche de GRH territoriale. Notre étude empirique porte sur la démarche de GTEC mise en œuvre par le cluster technologique de Sophia Antipolis. Grâce à la théorie de l’acteur-réseau, notre recherche révèle les mécanismes d’engagement qui font que les acteurs deviennent des parties prenantes engagées durablement dans une telle démarche : la capacité des parties prenantes à (re)problématiser rapidement et dans plusieurs directions le projet initial ; des dispositifs d’intéressement solides et réguliers, véhiculés par une plateforme numérique et une communication multicanal active ; un enrôlement de type intensif, maintenant les rôles préexistants pour une meilleure résistance aux processus de contre-enrôlement et pour une acceptabilité sociale des conséquences relationnelles des dispositifs ; un management polyphonique porté par un duo de traducteurs, transformés en « boundary spanners » (le chef de projet et la plateforme numérique). Ces mécanismes peuvent être considérés comme autant de facteurs clés de réussite à l’engagement durable des parties prenantes dans une démarche de GRH territoriale.
Une logique de l’écart dans les choix narratifs des conteurs de L’Heptaméron de Marguerite de Navarre
Authors: Piana Lou-Andréa 
Published: December 2018

Les dix conteurs de L’Heptaméron de Marguerite de Navarre disposent tous de caractéristiques distinctes et de sujets de prédilection : leurs nouvelles présentent ainsi une unité de thème ou de registre. Pourtant, presque chaque conteur propose, une fois dans le recueil, une nouvelle qui ne correspond pas à ses habitudes. Cet article étudie ces écarts comme s’inscrivant dans une logique des personnages, soit en laissant entrevoir leur évolution évangélique (ce qui transparaît dans la Nouvelle 67, contée par Simontault, l’exemple le plus remarquable de ces écarts), soit en révélant d’autres aspects de leur caractère ou de leur passé. Mais Saffredent, le plus ironique d’entre eux, souligne d’autant plus cette logique de l’écart qu’il en joue pour duper ses auditeurs par sa maîtrise de l’art de conter. L’apparente disjonction entre un récit et les autres d’un même conteur est alors révélatrice de la complexité des personnages, mais aussi de l’œuvre elle-même.
Arnalte et Lucenda , ou l’amant bien traité (des traducteurs)
Authors: Duché-Gavet Véronique 
Published: December 2018

Cet article retrace le fabuleux destin du Tractado de amores de Arnalte y Lucenda de Diego de San Pedro. Ce petit roman, qui narre les mésaventures sentimentales du chevalier Arnalte, éconduit par la belle Lucenda, s’est forgé une belle carrière hors d’Espagne, circulant d’abord en France, puis en Angleterre, en Italie, en Flandre et en Allemagne. L’examen de l’appareil titulaire, du paratexte et de la fable permet de prendre la mesure du dialogue entre les cultures castillane et française d’abord, française et européenne ensuite, et de s’interroger sur l’existence d’une littérature européenne à la Renaissance.
Corneal Light Backscatter Measured by Optical Coherence Tomography After LASIK
Authors: Wang Jianhua , Thomas Joseph , Cox Ian 
Published: December 2018

ABSTRACT
PURPOSE: To objectively quantify corneal light backscatter after LASIK using optical coherence tomography (OCT).
METHODS: Twenty-eight eyes of 14 patients (mean age: 39.9±8.6 years) underwent LASIK surgery. Corneal images were taken with a custom built anterior segment OCT at 1310 nm before and 1 day, 1 week, and 1 month after surgery. Backscattered light from the epithelium and 10 equally divided corneal stromal layers of the central cornea were analyzed using custom software. Light scattering of the interface area (defined as seven image pixels [46.2 µm] in depth centered by the peak corresponding to the interface between the corneal flap and bed) was also calculated and compared to the light backscatter at an equivalent depth of the respective preoperative cornea.
RESULTS: There were significant differences of light backscatter in different layers (analysis of variance [ANOVA]: F^sub (10, 130)^ =44.89, P=.0001), but no significant differences between right and left eyes preoperative^ (ANOVA: F^sub (10, 130)^=1.16, P=.32). After surgery, there were significant differences in light backscatter profiles of the central cornea (repeated measures ANOVA: F^sub (30, 810)^=7.70, P=.0001) with significant increases at approximately 140 to 190 µm in depth from the corneal front surface at 1 day (post hoc test: P=.004) and 1 week (post hoc test: P=.001) postoperatively, compared to the baseline. One month after surgery, light backscatter increased significantly in the epithelium (post hoc test: P=.0001) and decreased significantly (post hoc test: P=.0001) at approximately 100 to 140 µm in depth. Light backscatter results of these interface areas (repeated measures ANOVA: F^sub (3, 81)^=21.29, P=.0001) showed significant increases at 1 day and 1 week postoperatively (post hoc tests: P=.0001) compared to baseline results and 1-month postoperative results.
CONCLUSIONS: Objective and quantitative analysis of corneal light backscatter from OCT demonstrated increasing corneal light scattering at the interface and subsequent recovery. [J Refract Surg. 2006;22:604-610.]
Ultrasound and Partial Coherence Interferometry With Measurement of Central Corneal Thickness
Authors: Much Martin Michael , Haigis Wolfgang 
Published: December 2018

ABSTRACT
PURPOSE: To compare noncontact pachymeter measurements with ultrasound pachymeter measurements and assess their reproducibility.
METHODS: Central corneal thickness was measured in 104 eyes of 56 patients with three laser interference pachymeters (OLCR [Haag Streit, Könitz, Switzerland], OCP [4optics AG, Lübeck, Germany], and ACMaster [Carl Zeiss Méditée, Jena, Germany]) and an ultrasound pachymeter (Tomey AL2000 [Tomey Corp, Nagoya, Japan]).
RESULTS: Compared to the ultrasound measurements, the mean difference for the laser interference pachymeter measurements were +8.8 µm (standard deviation [SD] 5.68) for the OLCR, -8.0 µm (SD 5.39) for the OCR and -0.12 µm (SD 5.88) for the ACMaster. Reproducibility could only be estimated as not all of the devices allowed access to individual measurements. For all laser interference devices, reproducibility was estimated to be approximately 2 µm. Ultrasound measurements yielded a reproducibility of approximately 3.4 µm.
CONCLUSIONS: Although ultrasound pachymeter measurements differed significantly from OLCR and OCP measurements, agreement was considered good because the mean differences were <10 µm, and the results can be regarded as clinically interchangeable. [J Refract Surg. 2006;22:665-670.]
Comparison of Corneal Thickness Measured With Optical Coherence Tomography, Ultrasonic Pachymetry, and a Scanning Slit Method
Authors: Thomas Joseph , Wang Jianhua , Rollins Andrew M , Sturm Julie 
Published: December 2018

ABSTRACT
PURPOSE: To investigate the relationship between 1310-nm optical coherence tomography (OCT), an ultrasound pachymeter, and the Orbscan Il (Bausch & Lomb, Rochester, NY) in corneal thickness measurements before and after LASIK.
METHODS: Twenty-eight eyes of 14 patients with a mean age of 39.9 ±8.6 years underwent LASIK for correction of myopia with or without astigmatism. Central corneal thickness was measured with real-time 1310-nm OCT and Orbscan preoperatively and 1 day, 1 week, and 1 month postoperatively, and with an ultrasound pachymeter preoperatively and 1 month postoperatively.
RESULTS: Measurements of corneal thickness by all instruments correlated well with one another pre- and postoperatively r value range: 0.87 to 0.94, P<.05); however, there were significant differences among these methods (ANOVA: P<.005). Baseline readings for ultrasound and Orbscan were similar, as were readings 1 month postoperatively for OCT and Orbscan (P>.05). Thickness measured by OCT was thinner than for other instruments preoperatively (P<.005) and thicker than Orbscan postoperatively (P<.005). Significant corneal thinning (P<.001) was found with all study devices 1 day after laser ablation. Significant corneal thinning (P<.005) was found with OCT and Orbscan 1 week compared to 1 day postoperatively, and thickening (post hoc: P<.001) was evident at 1 month compared to 1 week postoperatively.
CONCLUSIONS: Although the instruments correlated well in measuring corneal thickness after LASIK, there were significant differences. All instruments indicated corneal swelling and recovery during the first postoperative week and thickening at 1 month. [J Refract Surg. 2006;22:671-678.]
Customized LASIK Treatment for Myopia: Relationship Between Preoperative Higher Order Aberrations and Refractive Outcome
Authors: Subbaram Manoj V , MacRae Scott M , Slade Stephen G , Durrie Daniel S 
Published: December 2018

ABSTRACT
PURPOSE: To analyze the effect of preoperative higher order aberrations on postoperative sphere and cylinder outcome.
METHODS: Three hundred thirty myopic eyes (mean: -3.32+1.54 diopters [D], range: -1.0 to -7.0 D) treated with customized ablation using the Technolas 217z laser (Bausch & tomb) were followed through 6 months after LASIK. Pre- and postoperative visual acuity, higher order root mean square (RMS), third order RMS, and spherical aberration were compared to study the safety and efficacy of the treatment. The relationship between preoperative higher order aberrations and manifest refraction after LASIK was analyzed.
RESULTS: Following LASIK, 91.5% of eyes obtained an uncorrected visual acuity of 2=20/20 and 70.3% of eyes obtained 20/16 without retreatment; 99% had a best spectacle-corrected visual acuity of s* 20/20 (75.9% of eyes were within ±0.50 D). Mean value of significant increase in postoperative higher order aberrations was 0.12+0.18 µm (P<.0001). Increased spherical aberration was associated with increased myopia treatment (P<.0001). Greater positive spherical aberration after LASIK was significantly correlated to postoperative hyperopia (overcorrection). Change in third order RMS was significantly correlated to change in spherical equivalent refraction among eyes with postoperative astigmatism (P<.0001).
CONCLUSIONS: With the Bausch & tomb Technolas 217z Zyoptix software, treatment of higher order aberrations, especially third order (coma and trefoil) and spherical aberration, significantly improved postoperative refractive status. [J Refract Surg. 2006;22:746-753.]
