Autonomía privada y contrato
Authors: Leyva Saavedra José 
Published: October 2020

Una de las instituciones que marca el paso del desarrollo del derecho privado no cabe duda de que es la ayer denominada autonomía de la voluntad y hoy mejor precisada autonomía privada; esto es, aquella libertad de los particulares, reconocida por los ordenamientos jurídicos, de regular sus propias relaciones jurídicas de la forma y manera querida por ellos. El derecho recorta, como bien se ha dicho, la superficie de la libertad existencial y devuelve, como recompensa, la libertad jurídica de las personas, organizada y precisada, para proyectar, perseguir sus propios objetivos, pero dentro de los límites señalados por cada ordenamiento. La indicada libertad está considerada dentro de los derechos fundamentales de las personas y encuentra su mejor plasmación en el contrato, posicionando en esta sede la autonomía contractual.
A pesar de su consideración de pieza maestra de las relaciones jurídicas privadas, la autonomía privada no tiene un espacio específico y explícito dentro de las Constituciones Políticas de los Estados, lo que realmente es preocupante, ya que se prefiere darle rango constitucional a una de las expresiones de tal autonomía, como es la libertad contractual.
Extraordinary optical transmission and enhanced magneto-optical Faraday effects in one-dimensional metallic gratings
Authors: Lei Chengxin , Man Zhongsheng , Tang Shaolong 
Published: October 2020

Abstract
The optical and magneto-optical (MO) properties of two different magneto-optic-plasmonic structures including double-layer and single-layer metallic gratings have been investigated. Numerical simulations based on the extended finite difference time domain method have revealed that, in the two proposed structures, apart from the extraordinary optical transmission effect, there arises high MO Faraday rotation in a broad spectrum spanning visible to near-infrared frequencies. Despite the easy fabrication process, the double-layer grating structure still shows an enhancement in transmittance, Faraday rotation, and figure of merit by two, five, and two times, respectively, compared to the single-layer structure, and this can be further improved by suitably modifying the configuration. The physical mechanisms of the physical phenomena are explained in detail.

Published: October 2020

Zakat is one of the instruments for well-being distribution. Zakat is also one of the most significant institution of Islam, in early Islamic zakat proved to be an extremely effective tool for poverty alleviation and inclusive finance. Total potential of zakat in the OIC member countries ranges from 1.8 percent to 4.34 percent of their GDP. Zakat has the potential to be developed economically. In contrary, development and performance of zakat institutions was relatively poor and this is illustrated by the collection of zakat in Muslim countries on average very low, less than 1% of GDP.
Maqashid Syariah is considered intellectual methodologies for Islamic studies and Non-Law studies. This has been used by the Muslim scholars to propose Islamic reform and revival in many aspects of live and to address problems of the Ummah in a way that is in line with Islamic tradition and aspirations. The institutions could make the Maqashid Sharia as an essential benchmark to design zakat distribution programs in both countries.
Zakat Institution objective should be the leading institution in economic empowerment of society by enacted Maqashid Sharia as the basis of designing the sustainable empowerment indicators. This paper aims to analyze and evaluate institutional program of collecting zakat in reaching Maqashid sharia and to identify the issues and the strategies of Zakat institutions. This study presents a comparison of zakat distribution programs between two countries, Indonesia and Malaysia, represented by Bazis DKI Jakarta and LZS in achieving five Maqashid Sharia aspects. This paper contributes to sustain the social life development in terms of the proper Zakat distribution by considering Maqashid Sharia. The originality of this paper is to provide provide insight for strategy on how Zakat institution could optimize their potency in achieving Maqashid Sharia.

Published: October 2020

Abstract
Most of the molecules detected thus far in exoplanet atmospheres, such as water and CO, are present for a large range of pressures and temperatures. In contrast, metal hydrides exist in much more specific regimes of parameter space, and so can be used as probes of atmospheric conditions. Iron hydride (FeH) is a dominant source of opacity in low-mass stars and brown dwarfs, and evidence for its existence in exoplanets has recently been observed at low resolution. We performed a systematic search of archival CARMENES near-infrared data for signatures of FeH during transits of 12 exoplanets. These planets span a large range of equilibrium temperatures (600

4000 K) and surface gravities (2.5

3.5). We did not find a statistically significant FeH signal in any of the atmospheres, but obtained potential low-confidence signals (signal-to-noise ratio ∼ 3) in two planets, WASP-33b and MASCARA-2b. Previous modeling of exoplanet atmospheres indicate that the highest volume mixing ratios (VMRs) of 10−7 to 10−9 are expected for temperatures between 1800 and 3000 K and log

. The two planets for which we find low-confidence signals are in the regime where strong FeH absorption is expected. We performed injection and recovery tests for each planet and determined that FeH would be detected in every planet for VMRs

, and could be detected in some planets for VMRs as low as

. Additional observations are necessary to conclusively detect FeH and assess its role in the temperature structures of hot-Jupiter atmospheres.
On the Investigation of the Closure Relations for Gamma-Ray Bursts Observed by Swift in the Post-plateau Phase and the GRB Fundamental Plane

Abstract
Gamma-ray Bursts (GRBs) are the most explosive phenomena in the universe after the big bang. A large fraction of GRB lightcurves (LCs) shows X-ray plateaus. We perform the most comprehensive analysis of all GRBs (with known and unknown redshifts) with plateau emission observed by The Neil Gehrels Swift Observatory from its launch until 2019 August. We fit 455 LCs showing a plateau and explore whether these LCs follow closure relations, relations between the temporal and spectral indices of the afterglow, corresponding to two distinct astrophysical environments and cooling regimes within the external forward shock (ES) model, and find that the ES model works for the majority of cases. The most favored environments are a constant-density interstellar or wind medium with slow cooling. We also confirm the existence of the fundamental plane relation between the rest-frame time and luminosity at the end of the plateau emission and the peak prompt luminosity for this enlarged sample, and test this relation on groups corresponding to the astrophysical environments of our known redshift sample. The plane becomes a crucial discriminant corresponding to these environments in terms of the best-fitting parameters and dispersions. Most GRBs for which the closure relations are fulfilled with respect to astrophysical environments have an intrinsic scatter σ compatible within 1σ of that of the “Gold” GRBs, a subset of long GRBs with relatively flat plateaus. We also find that GRBs satisfying closure relations indicating a fast cooling regime have a lower σ than ever previously found in literature.

Abstract
Rotational modulations of emission spectra in brown dwarf and exoplanet atmospheres show that clouds are often distributed non-uniformly in these ultracool atmospheres. The spatial heterogeneity in cloud distribution demonstrates the impact of atmospheric dynamics on cloud formation and evolution. In this study, we update the Hubble Space Telescope (HST) time-series data analysis of the previously reported rotational modulations of WISEP J004701+680352—an unusually red late-L brown dwarf with a spectrum similar to that of the directly imaged planet HR 8799e. We construct a self-consistent spatially heterogeneous cloud model to explain the HST and the Spitzer time-series observations, as well as the time-averaged spectra of WISE 0047. In the heterogeneous cloud model, a cloud thickness variation of around one pressure scale height explains the wavelength dependence in the HST near-IR spectral variability. By including disequilibrium CO/CH4 chemistry, our models also reproduce the redder

color of WISE 0047 compared to that of field brown dwarfs. We discuss the impact of vertical cloud structure on atmospheric profile and estimate the minimum eddy diffusivity coefficient for other objects with redder colors. Our data analysis and forward modeling results demonstrate that time-series spectrophotometry with a broad wavelength coverage is a powerful tool for constraining heterogeneous atmospheric structure.
Surface Brightness Evolution of Galaxies in the CANDELS GOODS Fields up to z ∼ 6: High-z Galaxies Are Unique or Remain Undetected
Authors: Whitney A. , Conselice C. J. , Duncan K. , Spitler L. R. 
Published: October 2020

Abstract
We investigate the rest-frame ultraviolet (UV, λ ∼ 2000 Å) surface brightness (SB) evolution of galaxies up to z ∼ 6 using a variety of deep Hubble Space Telescope (HST) imaging. UV SB is a measure of the density of emission from mostly young stars and correlates with an unknown combination of star formation rate, initial mass function, cold gas mass density, dust attenuation, and the size evolution of galaxies. In addition to physical effects, the SB is, unlike magnitude, a more direct way in which a galaxy’s detectability is determined. We find a very strong evolution in the intrinsic SB distribution that declines as

, decreasing by 4–5 mag arcsec−2 between z = 6 and z = 1. This change is much larger than expected in terms of the evolution in UV luminosity, sizes, or dust extinction, and we demonstrate that this evolution is “unnatural” and due to selection biases. We also find no strong correlation between mass and UV SB. Thus, deep HST imaging is unable to discover all of the most massive galaxies in the distant universe. Through simulations we show that only ∼15% of galaxies that we can detect at z = 2 would be detected at high z. We furthermore explore possible origins of high-SB galaxies at high z by investigating the relationship between intrinsic SB and star formation rates. We conclude that ultra–high-SB galaxies are produced by very gas-rich dense galaxies that are in a unique phase of evolution, possibly produced by mergers. Analogs of such galaxies do not exist in the relatively nearby universe.
Approche intersectionnelle et postcoloniale d’un privilège
Authors: Le Renard Saba A. 
Published: October 2020

À partir d’une enquête sociologique sur le privilège occidental tel qu’il se déploie entre Dubaï et la France, cet article intervient dans deux débats au sein du champ de l’intersectionnalité : comment cette notion peut-elle se combiner avec les approches transnationales et postcoloniales ? Est-il pertinent d’utiliser l’intersectionnalité pour travailler sur des personnes en position dominante ? L’article montre qu’à Dubaï, tou·te·s les titulaires de passeports occidentaux bénéficient d’avantages, mais pas des mêmes avantages : les contrats d’expatriation et packages famille suravantagent des hommes blancs. Le fossé entre les expériences se creuse à moyen terme. Certain·e·s sont mobiles, tandis que d’autres se sentent contraint·e·s de rester à Dubaï. Certaines carrières, notamment de femmes non-blanches, tournent court. L’expérience d’un privilège est alors précaire et éphémère. Enfin, les projections en France sur le Golfe n’affectent pas tou·te·s les personnes qui en reviennent de la même manière.

Published: October 2020

O presente artigo busca problematizar – a partir das inquietações de um professor da referida rede pública do Estado do Rio de Janeiro (integrante do grupo de autores deste estudo -, a lógica produtora de ausências epistêmicas, que subjaz aos projetos temáticos das escolas da rede pública de educação, mesmo quando estes buscam seguir as diretrizes da legislação educacional brasileira que aspira uma perspectiva interdisciplinar. O artigo empreende uma análise teórico-epistemológica a partir das propostas (estruturas) do Currículo e o (do) Projeto Político Pedagógico do Colégio Estadual Johenir Henriques Viégas em diálogo com os estudos de Santos (1987, 2007, 2008), Foucault (1999), Lopes (2011) Morin (2000, 2010), Larrosa (2003, 20013) e Maturana (2005), que constituem o referencial teórico utilizado na reflexão, com o qual os autores buscam propor outros sentidos para a Interdisciplinaridade.

Este artigo objetiva identificar de que maneira a legislação que institucionalizou provas para concurso para o magistério primário contribuiu para a definição dos saberes necessários à prática docente e para a configuração do trabalho docente na província de Sergipe na década de 70 do século XIX. Para tanto, tomou-se como base a contribuição teórico-metodológica da História Cultural e as discussões de Elias (1994, 2001), Tardif (2014) e Amorim (2014), com o intuito de compreender como se configurou e se institucionalizou a profissão docente em Sergipe, identificando os saberes necessários à prática profissional, assim como as tensões no campo, mais especificamente no âmbito do ensino primário, verificando, assim, de que forma se constituiu o perfil profissional pensado para o projeto de constituição de nação para o Brasil. Utilizando como fontes documentos manuscritos como ofícios, cartas e projetos de leis identificados no acervo da Biblioteca Nacional, além de provas de concurso para professores primários encontradas no Acervo Público do Estado de Sergipe, notou-se que os saberes docentes necessários à prática profissional estavam imbuídos de forte apelo moral e religioso, aspectos que deveriam compor o perfil profissional dos que seriam responsáveis por formar as bases da sociedade sergipana.

Within social groups, feeding competition and predation pressure affect individual spatial position. The costs and benefits associated to each position are likely to influence the time that individuals allocate to different activities. Whether the effect of spatial positioning on activity budget differs between individuals of different sex or dominance rank remains unclear. This study aimed at investigating the effect of within-group spatial position on the activity budget of male and female sooty mangabeys. Focal behavioral observations was used to collect the individual location and behavior every 15 minutes (N=5115 locations) on 29 individuals from a wild group of sooty mangabeys (Cercocebus atys) in the Taï National Park. The joint effect of rank, sex and spatial position on individual‟s activity budget was investigated. Females were more central in the group and both fed and rested more than males, independently of their rank. High-ranking individuals from both sexes were more likely to be central and both fed and rested longer than low-ranking ones. Females and high-ranking individuals from both sexes benefit from their social status by adopting spatial positions in the community that could influence their fitness positively. These results are discussed to improve our understanding of social dynamics in wild primates.Keywords: Spatial position, primates, socio-ecology, social dynamics.
