Comunidades quilombolas do sertão de Pernambuco: diálogos sociopolíticos na construção de uma educação emancipatória
Authors: Silva Luclécia C. M. , Carvalho Neto Moisés Felix de , Busso Adriana Fernanda 
Published: August 2017

Os povos quilombolas possuem uma longa história de luta por uma educação dequalidade, sobretudo os povos do Semiárido nordestino. Assim, a partir de dispositivos normativos e da luta dos movimentos sociais, houve um grande avanço na criação de diversas politicas públicas, destacando-se os programas educacionais destinados à valorização da diversidade sociocultural no campo. Sabendo disso, a presente pesquisa teve como objetivo analisar as relações e contribuições de aspectos sociopolíticos na construção de uma educação emancipatória em comunidades quilombolas insertadas no contexto do Semiárido nordestino. Optou-se pela pesquisa e abordagem qualitativa,de caráter exploratório e de base etnográfica, com procedimentos metodológicos, como: observações diretas, entrevistas semiestruturadas, grupos focais, caminhadas transversais, registros fotográficos, entre outros, com posterior triangulação dos dados. Verificou-se que os processos educativos se mostram o diferencial no empoderamento e tomada de decisões relativas à reafirmação de uma alteridade que estão cotidianamente ressignificando na luta pela valorização quilombola. Assim, empreende-se que as ações públicas de fortalecimento do patrimônio cultural e imaterial desses grupos sociais não serão efetivadas apenas pela existência de uma legislação específica paraeducação escolar quilombola, mas dependem muito mais do esforço em conjunto e integrado dos coletivos quilombolas na busca pelo respeito ao éthos (modo de ser) quilombola na elaboração das atividades pedagógicas que respeitem as especificidades locais e perpetuem os elementos culturais que constroem a identidade étnica de cada comunidade.
The Effects of Social Support on the Relationship between Infant Sleep and Postnatal Depression
Authors: King Yaroslava 
Published: August 2017

To date, research on social support as a factor affecting the relationship between infant sleep and postnatal depression (PND) has not been widely examined. This study aimed to determine the extent to which social support affects this relationship. The sample consisted of 108 caregivers of children between 6-18 months of age. Participants completed an online survey comprised of the Edinburgh PostnatalDepression Scale, The Social Provisions Scale and The Brief Infant Sleep Questionnaire. Results indicated that parents of children who were sleep disturbed had higher levels of PND and less social support. Correlations between PND and nocturnal sleep (r = -.231, p = .016) and nocturnal wakefulness (r = -.228, p = .018) were significant. Social support was also significantly correlated with nocturnal sleep (r = .329, p = .001) and nocturnal wakefulness (r = .199, p = .039). A significant negative relationship between social support and PND was found (r = -.539, p = .000). No moderating effect of social support on the relationship between child sleep disturbance and PND was found for either sleep variables (b = -0.014, 95% CI [-0.099, 0.071], t = -0.33, p = .745; b = 0 .065, 95% CI [-0.267, 0.396], t = 0.39, p = .700). Overall, the results conclude that social support has a substantial impact on both PND and a child’s sleep problems. Although a significant moderating effect of social support was not found, the significant correlations reveal that further research is needed.

Published: August 2017

This paper is a contribution to the knowledge of the crustal structure of the eastern flank of the Valle Fértil - La Huerta ranges (Western Sierras Pampeanas, San Juan, Argentina) at 31°S, in the Andean foreland region, where the Nazca plate is subducting horizontally at about 100 km depth. A 1D velocity model was constrained, combining petrographic and seismological observations from analysis of 19 igneous and metaigneous plutonic rocks belonging to the Famatinian (Ordovician) magmatic arc, which make up most of the crystalline basement of these ranges. Granitoid lithologies predominate in the northern region whereas mafic lithologies are more common to the south. The seismological analysis consisted of modeling teleseismic receiver functions near three seismological stations: LUNA, MAJA and CHUC, in places where those rocks are dominant. Thus, P and S seismic-wave velocities (Vp and Vs) and Poisson´s coefficient (ν), among other elastic parameters, were obtained. The seismic velocity model indicates an overthickened crust with an average thickness between 55 and 60 km, which matches with global average values (~41km); this agrees well with the hypothesis of partial eclogitization in the lower crust. The presence of two seismic velocity discontinuities at mid-crustal levels (12 and 28 km depths), likely associated to décollements, might be related to the accretion of the Cuyania terrane to the Pampia terrane. We obtained low P seismic-wave velocities (Vp ~5.8 km/s), Vp/Vs ratio (~1.70) in upper crust levels consistent with granitoid lithologies, as well as high P seismic-wave velocities (Vp ~6.76 km/s), Vp/Vs ratio (~1.78) in lower crust levels; these figures match with mafic lithologies of a more dense (~3.00 g/cm3), lower crust with respect to other back-arc Andean regions. Also, these values are consistent with the existence of mafic rocks composed of olivine, ortho- and clinopyroxene, which constitute the root of the Famatinian magmatic arc. These results indicate high-grade metamorphic conditions and depths corresponding to geophysical properties of middle to lower crust and correlate with the hypothesis of a dehydrated, cool and magnesium-enriched mantle located in the region between the subducted Nazca slab and the bottom of the Cuyania terrain crust.

Bats in the Belfry: On the Relationship of Cybernetics and German Media Theory
Authors: Müggenburg Jan 
Published: August 2017

Background When German media theory (GMT) took shape in the early 1980s it was influenced by cybernetic concepts; however, it eventually discovered the history of cybernetics as an object of research.Analysis The article follows the assumption that GMT’s double reference to cybernetics must be characterized as the result of both a shared epistemology and a specific discursive constellation. After contrasting McCulloch’s concept of a synthetic physiological a priori and Kittler’s concept of a technological a priori it examines how GMT adopted concepts from cybernetics, and how its members eventually became fascinated by the history of cybernetics.Conclusion and implications The article concludes that the double reference to cybernetics explains its special role in GMT, while raising problems for GMT’s current fascination with cybernetics.
Constitucionalismo, Estado y territorio en el contexto de la globalización
Authors: Jiménez William Guillermo 
Published: August 2017

La globalización muestra que el Estado nacional está perdiendo el monopolio en la producción del derecho y esto genera cambios en cuanto al ámbito de aplicación de los ordenamientos jurídicos estatales y el papel del territorio como límite de los mismos. El objetivo de este trabajo es ofrecer un panorama acerca de los impactos de la globalización del derecho en el Estado, la teoría constitucional y el territorio. El estudio se realiza mediante la técnica de la revisión documental acudiendo a la consulta de diversas fuentes. Se concluye que se ha debilitado el modelo westfaliano del Estado nación; sin embargo, la globalización requiere del Estado para funcionar. El derecho se ha desterritorializado, y el territorio sigue siendo un elemento fundamental para el Estado contemporáneo.

Las prácticas de creación artística en el Urabá antioqueño. Patrimonio cultural inmaterial no visibilizado
Authors: Restrepo Martha Helena Valencia 
Published: August 2017

Esta investigación presenta un estado del arte sobre las prácticas de creación artística en seis municipios del Urabá antioqueño. Preguntarse por la invisibilidad del artista creador en el contexto de esta zona obliga a revisar, de soslayo, pormenores sociohistóricos de una subregión estratégica en la geografía colombiana cuyas dinámicas económicas, etnográficas y culturales actuales han emergido de la lucha constante en y por un territorio vasto y provisto de grandes riquezas naturales. Con aproximadamente el 50% de población afrodescendiente, el 15% de población indígena y el 35% de población mestiza, la subregión ha forjado un interesante panorama pluricultural privilegiado en expresiones artísticas que se nutren de un sinnúmero de tradiciones y costumbres propias de los grupos humanos que allí convergen; expresiones y prácticas de las cuales muchos de sus creadores no están aún identificados, reconocidos o visibilizados, asunto de competencia de las políticas públicas culturales del Estado colombiano.

Published: August 2017

Background:
Juvenile nasopharyngeal angiofibroma (JNA) also called as bleeding fibroma as this is highly vascular tumor. This is a benign tumor of prepubertal and young adults which is locally aggressive and has got tendency to bleed. The extension of the tumor takes place because of potential available in nasopharyngeal space.

Case presentation:
We present two cases of juvenile nasopharyngeal angiofibromas in different stages with highlighting the role of contrast enhanced computerized tomography (CECT).

Conclusion:
We emphasize over the clinico-radiological evaluation for making the diagnosis. The correct pre-operative radiological staging is mandatory prerequisite for the surgical management.

SURFACE STRATEGY TAXONOMY ON THE EFL STUDENTS’ COMPOSITION A STUDY OF ERROR ANALYSIS
Authors: Suhono Suhono 
Published: August 2017

This study deals with error analysis on composition written by EFL Students IAIM NU Metro. It aims at developing further analyzing of error analysis in second language learners. For this purpose, an empirical study was conducted, using Indonesian students learning English as the subject of research. To achieve this purpose, the researcher explored the type of grammatical errors made by students at different grade semesters: the second, the sixth, and the eighth. More specifically, this study was an attempt to describe the type of grammatical error which frequently exist in written composition, to describe frequency grammatical error among the grade semesters, and to describe the sources of errors. Students’ writings were analyzed based on surface strategy taxonomy theory. The results of this research revealed that 268 sentences indicated errors. In all semesters, types of omission error was the highest one 131 (48.9%) sentences. Furthermore, grammatical error in the second semester was the highest one 124 (46.8%) sentences. The sources of errors of this research were mother-tongue influence (Interlingual errors). It was influenced by the native language which interferes with target language learning. The second was Intralingual errors, caused by the target tself like, misanalysis (wrong hypothesis), incomplete rule application.

Published: August 2017

Abstract
We report the results of a pilot program to use the Magellan/M2FS spectrograph to survey the galactic populations and internal kinematics of galaxy clusters. For this initial study, we present spectroscopic measurements for 223 quiescent galaxies observed along the line of sight of the galaxy cluster Abell 267 (

). We develop a Bayesian method for modeling the integrated light from each galaxy as a simple stellar population, with free parameters that specify the redshift (

/c) and characteristic age, metallicity (

), alpha-abundance (

), and internal velocity dispersion (

) for individual galaxies. Parameter estimates derived from our 1.5 hr observation of A267 have median random errors of

A Statistical Survey of Peculiar L and T Dwarfs in SDSS, 2MASS, and WISE
Authors: Kellogg Kendra , Metchev Stanimir , Miles-Páez Paulo A. , Tannock Megan E. 
Published: August 2017

Abstract
We present the final results from a targeted search for brown dwarfs with unusual near-infrared colors. From a positional cross-match of the Sloan Digital Sky Survey (SDSS), 2-Micron All-Sky Survey (2MASS), and Wide-Field Infrared Survey Explorer (WISE) catalogs, we have identified 144 candidate peculiar L and T dwarfs. Spectroscopy confirms that 20 of the objects are peculiar or are candidate binaries. Of the 420 objects in our full sample 9 are young (

2.1%) and another 8 (1.9%) are unusually red, with no signatures of youth. With a spectroscopic

color of 2.58 ± 0.11 mag, one of the new objects, the L6 dwarf 2MASS J03530419+0418193, is among the reddest field dwarfs currently known and is one of the reddest objects with no signatures of youth known to date. We have also discovered another potentially very-low-gravity object, the L1 dwarf 2MASS J00133470+1109403, and independently identified the young L7 dwarf 2MASS J00440332+0228112, which was first reported by Schneider and collaborators. Our results confirm that signatures of low gravity are no longer discernible in low to moderate resolution spectra of objects older than ∼200 Myr. The 1.9% of unusually red L dwarfs that do not show other signatures of youth could be slightly older, up to ∼400 Myr. In this case a red

color may be more diagnostic of moderate youth than individual spectral features. However, its is also possible that these objects are relatively metal-rich, and thus have enhanced atmospheric dust content.
The Influence of Coronal Mass Ejections on the Mass-loss Rates of Hot-Jupiters
Authors: Cherenkov A. , Bisikalo D. , Fossati L. , Möstl C. 
Published: August 2017

Abstract
Hot-Jupiters are subject to extreme radiation and plasma flows coming from their host stars. Past ultraviolet Hubble Space Telescope observations, supported by hydrodynamic models, confirmed that these factors lead to the formation of an extended envelope, part of which lies beyond the Roche lobe. We use gas-dynamic simulations to study the impact of time variations in the parameters of the stellar wind, namely that of coronal mass ejections (CMEs), on the envelope of the typical hot-Jupiter HD 209458b. We consider three CMEs characterized by different velocities and densities, taking their parameters from typical CMEs observed for the Sun. The perturbations in the ram-pressure of the stellar wind during the passage of each CME tear off most of the envelope that is located beyond the Roche lobe. This leads to a substantial increase of the mass-loss rates during the interaction with the CME. We find that the mass lost by the planet during the whole crossing of a CME is of ≈1015 g, regardless of the CME taken into consideration. We also find that over the course of 1 Gyr, the mass lost by the planet because of CME impacts is comparable to that lost because of high-energy stellar irradiation.
Time Domain Filtering of Resolved Images of Sgr A∗
Authors: Shiokawa Hotaka , Gammie Charles F. , Doeleman Sheperd S. 
Published: August 2017

Abstract
The goal of the Event Horizon Telescope (EHT) is to provide spatially resolved images of Sgr A*, the source associated with the Galactic Center black hole. Because Sgr A* varies on timescales that are short compared to an EHT observing campaign, it is interesting to ask whether variability contains information about the structure and dynamics of the accretion flow. In this paper, we introduce “time-domain filtering,” a technique to filter time fluctuating images with specific temporal frequency ranges and to demonstrate the power and usage of the technique by applying it to mock millimeter wavelength images of Sgr A*. The mock image data is generated from the General Relativistic Magnetohydrodynamic (GRMHD) simulation and the general relativistic ray-tracing method. We show that the variability on each line of sight is tightly correlated with a typical radius of emission. This is because disk emissivity fluctuates on a timescale of the order of the local orbital period. Time-domain filtered images therefore reflect the model dependent emission radius distribution, which is not accessible in time-averaged images. We show that, in principle, filtered data have the power to distinguish between models with different black-hole spins, different disk viewing angles, and different disk orientations in the sky.
