Normalización, subjetividad y alternativas al bajo rendimiento escolar
Authors: Molina Pertuz Verónica Lucía , Cruz Bolaños Jonny Alexander 
Published: October 2016

El “bajo rendimiento académico” es considerado un factor que promueve el fracaso y la deserción escolar. Si la vida escolar es un escenario de socialización, las experiencias de fracaso o deserción tendrán implicaciones directas en su subjetividad que pueden ser determinantes en la participación social. El presente estudio busca comprender los procesos de configuración de subjetividad, dentro del escenario de socialización de la escuela, en aquellos niños y niñas que afrontan la condición de ser catalogados en el rango de “bajo rendimiento escolar”, mediante la exploración de las Funciones Cognitivas Superiores (en adelante FCS) desde la Neuropsicología y la exploración del concepto de “sí mismo”. El estudio se ha llevado a cabo mediante la exploración de la FCS y la indagación sobre el concepto de sí mismos, en dos escenarios: “Exploración en condiciones evaluativas” y “Exploración en condiciones no-evaluativas”. Los participantes son niños y niñas con edades comprendidas entre los 6 y 8 años, que pertenecen a colegios de ampliación de cobertura de la Arquidiócesis de Cali.
Por los abismos de la infancia
Authors: Ríos Madrid Myriam 
Published: October 2016

Constantemente los medios de comunicación nos informan sobre el maltrato al que son sometidos los niños en todo el mundo, maltrato que se expresa en variadísimas y crueles formas y contra el cual parecen impotentes las leyes que pretenden acabarlo. Un breve recorrido por la historia nos muestra que esta crueldad puesta sobre los infantes ha existido siempre, que forma parte de una agresividad estructural humana que encuentra en los niños un blanco fácil para su descarga.
Ruptura del paradigma subcortical en los procesos emocionales
Authors: Ríos Flórez Jorge Alexander , Cardona Agudelo Viviana 
Published: October 2016

El estudio de las emociones, su desarrollo, procesamiento y comprensión, se ha limitado a la funcionalidad de estructuras subcorticales; sin embargo, recientemente se han propiciado investigaciones que reorientan y amplían el campo de estudio del procesamiento emocional hacia vínculos con regiones corticales del cerebro. Pese a lo anterior, no se había planteado claramente la importancia de eliminar el sesgo localizacionista en los procesos emocionales; este artículo realiza un recorrido por los inicios griegos con tendencia científica en el abordaje y estudio de las emociones, y la evolución que estos preconceptos y resultados han tenido a lo largo del último par de siglos donde se ha intensificado la comprensión de la actividad cerebral, así como las limitantes que han logrado trascender a lo largo del último siglo y que presentan perspectivas parciales del funcionamiento y procesamiento emocional en los circuitos biológicos del cerebro. De igual forma, se hace pertinente resaltar la importancia de las emociones en regiones corticales, que intervienen en la actividad cognitiva y motora que allí se suscita, y cómo éstas pueden afectar o favorecer su funcionalidad.

Published: October 2016

Sin duda alguna, un par de páginas se han de quedar cortas a la hora de desglosar un poco sobre aquellos enfoques direccionados hacia el ser humano, desde lo individual, hasta su interacción en grupo y sociedad. Aun así, el presente artículo permite dar unamirada estructural y básica de lo que conlleva a la mención del concepto de Terapia Familiar Sistémica, en éste caso desarrollada en contextos de pobreza, básicamente en América Latina, y más específicamente en Colombia. A través de una contextualización estructurada de términos, ubicados en la raíz del tema principal, se pretende hacer un recorrido que vaya desde lo más sencillo, hasta lo más elaborado, para finalmente impregnar al lector, de una forma más clara y globalizada, de la ubicación y el universo que se constituye alrededor de la Terapia Familiar Sistémica, en los contextos de pobreza; su constitución, fundamento e importancia en nuestra sociedad.
La oralidad en el film El discurso del rey

Published: October 2016

El siguiente artículo pretende resaltar la importancia que la oralidad y el discurso tienen en el ámbito social de los seres humanos. El poder que representa el lenguaje, y su capacidad de persuadir, lo convierte en una herramienta que, mal utilizada, generará conflictos en la sociedad; además, se abordan las diferencias comunicativas como la tartamudez, para finalmente, generar, desde la opinión del autor, una postura crítica sobre algunos postulados teóricos y cómo estos se desarrollan en el ámbito social.
A Concept–Wide Association Study of Clinical Notes to Discover New Predictors of Kidney Failure
Authors: Singh Karandeep , Betensky Rebecca A. , Wright Adam , Curhan Gary C. , Bates David W. , Waikar Sushrut S. 
Published: October 2016

Background and objectives
Identifying predictors of kidney disease progression is critical toward the development of strategies to prevent kidney failure. Clinical notes provide a unique opportunity for big data approaches to identify novel risk factors for disease.

Design, setting, participants, & measurements
We used natural language processing tools to extract concepts from the preceding year’s clinical notes among patients newly referred to a tertiary care center’s outpatient nephrology clinics and retrospectively evaluated these concepts as predictors for the subsequent development of ESRD using proportional subdistribution hazards (competing risk) regression. The primary outcome was time to ESRD, accounting for a competing risk of death. We identified predictors from univariate and multivariate (adjusting for Tangri linear predictor) models using a 5% threshold for false discovery rate (q value <0.05). We included all patients seen by an adult outpatient nephrologist between January 1, 2004 and June 18, 2014 and excluded patients seen only by transplant nephrology, with preexisting ESRD, with fewer than five clinical notes, with no follow-up, or with no baseline creatinine values.

Results
Among the 4013 patients selected in the final study cohort, we identified 960 concepts in the unadjusted analysis and 885 concepts in the adjusted analysis. Novel predictors identified included high–dose ascorbic acid (adjusted hazard ratio, 5.48; 95% confidence interval, 2.80 to 10.70; q<0.001) and fast food (adjusted hazard ratio, 4.34; 95% confidence interval, 2.55 to 7.40; q<0.001).

Conclusions
Novel predictors of human disease may be identified using an unbiased approach to analyze text from the electronic health record.

Measuring and correcting wobble in large-scale transmission radiography
Authors: Rogers Thomas W. , Ollier James , Morton Edward J. , Griffin Lewis D. 
Published: October 2016

BACKGROUND: Large-scale transmission radiography scanners are used to image vehicles and cargo containers. Acquired images are inspected for threats by a human operator or a computer algorithm. To make accurate detections, it is important that image values are precise. However, due to the scale (∼5 m tall) of such systems, they can be mechanically unstable, causing the imaging array to wobble during a scan. This leads to an effective loss of precision in the captured image. OBJECTIVE: We consider the measurement of wobble and amelioration of the consequent loss of image precision. METHODS: Following our previous work, we use Beam Position Detectors (BPDs) to measure the cross-sectional profile of the X-ray beam, allowing for estimation, and thus correction, of wobble. We propose: (i) a model of image formation with a wobbling detector array; (ii) a method of wobble correction derived from this model; (iii) methods for calibrating sensor sensitivities and relative offsets; (iv) a Random Regression Forest based method for instantaneous estimation of detector wobble; and (v) using these estimates to apply corrections to captured images of difficult scenes. RESULTS: We show that these methods are able to correct for 87% of image error due wobble, and when applied to difficult images, a significant visible improvement in the intensity-windowed image quality is observed. CONCLUSIONS: The method improves the precision of wobble affected images, which should help improve detection of threats and the identification of different materials in the image.

Published: October 2016

BACKGROUND: Obstructive sleep apnea (OSA) affects both adults and children, likely mediated by the deficits of various brain regions. The association between structural alterations in the brain and OSA syndrome have been reported in adult patients, but the corresponding evidence for OSA children is still limited. OBJECTIVE: The proposed study aimed to investigate the structural alterations in the brain of children with OSA, with focus on basal ganglia structures. METHODS: We recruited 25 OSA children (aged 10.3±1.5 years) and 30 healthy children (aged 10.1±1.8 years) with T1-weighted brain MRI and performed automatic segmentation of their brains. The shape alterations of the basal ganglia structures for OSA syndrome was determined by comparison of the OSA group and control group with surface-based shape analysis. RESULTS: Differences in the morphometry of the left thalamus and the left pallidum were found between the OSA group and control group. Compared to the control group, the OSA group presented significant atrophy in the ventral posterior nucleus and the medial dorsal nucleus of the left thalamus, while regional dilation was found in both the internal and external segments of the left pallidum. CONCLUSION: These findings identified the association between the structural deficits of the thalamus and OSA syndrome in children, which was consistent with the existing findings in OSA adults. In addition, the present study provided new insights to the distinctive pattern of structural changes of the pallidum in pediatric OSA when compared to adult OSA.

ABSTRACT
We use K2 to continue the exploration of the distribution of rotation periods in Pleiades that we began in Paper I. We have discovered complicated multiperiod behavior in Pleiades stars using these K2 data, and we have grouped them into categories, which are the focal part of this paper. About 24% of the sample has multiple, real frequencies in the periodogram, sometimes manifesting as obvious beating in the LCs. Those having complex and/or structured periodogram peaks, unresolved multiple periods, and resolved close multiple periods are likely due to spot/spot group evolution and/or latitudinal differential rotation; these largely compose the slowly rotating sequence in P versus (V − K
s)0 identified in Paper I. The fast sequence in P versus (V − K
s)0 is dominated by single-period stars; these are likely to be rotating as solid bodies. Paper III continues the discussion, speculating about the origin and evolution of the period distribution in the Pleiades.
DEPENDENCE OF X-RAY BURST MODELS ON NUCLEAR REACTION RATES

Published: October 2016

ABSTRACT
X-ray bursts are thermonuclear flashes on the surface of accreting neutron stars, and reliable burst models are needed to interpret observations in terms of properties of the neutron star and the binary system. We investigate the dependence of X-ray burst models on uncertainties in (p, γ), (α, γ), and (α, p) nuclear reaction rates using fully self-consistent burst models that account for the feedbacks between changes in nuclear energy generation and changes in astrophysical conditions. A two-step approach first identified sensitive nuclear reaction rates in a single-zone model with ignition conditions chosen to match calculations with a state-of-the-art 1D multi-zone model based on the Kepler stellar evolution code. All relevant reaction rates on neutron-deficient isotopes up to mass 106 were individually varied by a factor of 100 up and down. Calculations of the 84 changes in reaction rate with the highest impact were then repeated in the 1D multi-zone model. We find a number of uncertain reaction rates that affect predictions of light curves and burst ashes significantly. The results provide insights into the nuclear processes that shape observables from X-ray bursts, and guidance for future nuclear physics work to reduce nuclear uncertainties in X-ray burst models.
CO OBSERVATIONS AND INVESTIGATION OF TRIGGERED STAR FORMATION TOWARD THE N10 INFRARED BUBBLE AND SURROUNDINGS
Authors: Gama D. R. G. , Lepine J. R. D. , Mendoza E. , Wu Y. , Yuan J. 
Published: October 2016

ABSTRACT
We studied the environment of the dust bubble N10 in molecular emission. Infrared bubbles, first detected by the GLIMPSE survey at 8.0 μm, are ideal regions to investigate the effect of the expansion of the H ii region on its surroundings and the eventual triggering of star formation at its borders. In this work, we present a multi-wavelength study of N10. This bubble is especially interesting because infrared studies of the young stellar content suggest a scenario of ongoing star formation, possibly triggered on the edge of the H ii region. We carried out observations of 12CO(1-0) and 13CO(1-0) emission at PMO 13.7 m toward N10. We also analyzed the IR and sub-millimeter emission on this region and compare those different tracers to obtain a detailed view of the interaction between the expanding H ii region and the molecular gas. We also estimated the parameters of the denser cold dust condensation and the ionized gas inside the shell. Bright CO emission was detected and two molecular clumps were identified from which we have derived physical parameters. We also estimate the parameters for the densest cold dust condensation and for the ionized gas inside the shell. The comparison between the dynamical age of this region and the fragmentation timescale favors the “Radiation-Driven Implosion” mechanism of star formation. N10 is a case of particular interest with gas structures in a narrow frontier between the H ii region and surrounding molecular material, and with a range of ages of YSOs situated in the region, indicating triggered star formation.
DETERMINATION OF CORONAL MASS EJECTION PHYSICAL PARAMETERS FROM A COMBINATION OF POLARIZED VISIBLE LIGHT AND UV Lyα OBSERVATIONS
Authors: Susino R. , Bemporad A. 
Published: October 2016

ABSTRACT
Visible-light observations of Coronal Mass Ejections (CMEs) performed with coronagraphs and heliospheric imagers (in primis on board the Solar and Heliospheric Observatory and STEREO missions) have offered the best way to study the kinematics and geometrical structure of these fundamental events so far. Nevertheless, it has been widely demonstrated that only combination of multi-wavelength data (including X-ray spectra, EUV images, EUV-UV spectra, and radio dynamic spectra) can provide complete information on the plasma temperature and density distributions, non-thermal motions, magnetic fields, and other physical parameters, for both CMEs and CME-related phenomena. In this work, we analyze three CMEs by combining simultaneous data acquired in the polarized visible light by the LASCO-C2 coronagraph and in the UV H i Lyα line (1216 Å) by the UVCS spectrometer, in order to estimate the CME plasma electron density (using the polarization-ratio technique to infer the 3D structure of the CME) and temperature (from the comparison between the expected and measured Lyα intensities) along the UVCS field of view. This analysis is primarily aimed at testing the diagnostic methods that will be applied to coronagraphic observations of CMEs delivered by the Metis instrument on board the next ESA-Solar Orbiter mission. We find that CME cores are usually associated with cooler plasma (

K), and that a significant increase of the electron temperatures is observed from the core to the front of the CME (where

K), which seems to be correlated, in all cases, with the morphological structure of the CME as derived from visible-light images.

ABSTRACT
Many properties of the Milky Way’s (MW) dark matter halo, including its mass-assembly history, concentration, and subhalo population, remain poorly constrained. We explore the connection between these properties of the MW and its satellite galaxy population, especially the implication of the presence of the Magellanic Clouds for the properties of the MW halo. Using a suite of high-resolution N-body simulations of MW-mass halos with a fixed final

, we find that the presence of Magellanic Cloud-like satellites strongly correlates with the assembly history, concentration, and subhalo population of the host halo, such that MW-mass systems with Magellanic Clouds have lower concentration, more rapid recent accretion, and more massive subhalos than typical halos of the same mass. Using a flexible semi-analytic galaxy formation model that is tuned to reproduce the stellar mass function of the classical dwarf galaxies of the MW with Markov-Chain Monte-Carlo, we show that adopting host halos with different mass-assembly histories and concentrations can lead to different best-fit models for galaxy-formation physics, especially for the strength of feedback. These biases arise because the presence of the Magellanic Clouds boosts the overall population of high-mass subhalos, thus requiring a different stellar-mass-to-halo-mass ratio to match the data. These biases also lead to significant differences in the mass–metallicity relation, the kinematics of low-mass satellites, the number counts of small satellites associated with the Magellanic Clouds, and the stellar mass of MW itself. Observations of these galaxy properties can thus provide useful constraints on the properties of the MW halo.
DEPENDENCE OF THE Sr-TO-Ba AND Sr-TO-Eu RATIO ON THE NUCLEAR EQUATION OF STATE IN METAL-POOR HALO STARS
Authors: Famiano M. A. , Kajino T. , Aoki W. , Suda T. 
Published: October 2016

ABSTRACT
A model is proposed in which the dependence on the equation of state (EOS) of the scatter of [Sr/Ba] in metal-poor stars is studied. Light r-process element enrichment in these stars has been explained via a truncated r-process, or “tr-process.” The truncation of the r-process from a generic core-collapse event followed by a collapse into an accretion-induced black hole is examined in the framework of a galactic chemical evolution model. The constraints on this model imposed by observations of extremely metal-poor stars are explained, and the upper limits in the [Sr/Ba] distributions are found to be related to the nuclear EOS in a collapse scenario. The scatter in [Sr/Ba] and [Sr/Eu] as a function of metallicity has been found to be consistent with turbulent ejection in core-collapse supernovae. Adaptations of this model are evaluated to account for the scatter in isotopic observables. This is done by assuming mixing in ejecta in a supernova event. Stiff EOS are eliminated by this model.
NEW CONSTRAINTS ON THE MOLECULAR GAS IN THE PROTOTYPICAL HyLIRGs BRI 1202–0725 AND BRI 1335–0417

ABSTRACT
We present Karl G Jansky Very Large Array observations of CO(

) line emission and rest-frame 250 GHz continuum emission of the Hyper-Luminous IR Galaxies (HyLIRGs) BRI 1202–0725 (z = 4.69) and BRI 1335–0417 (z = 4.41), with an angular resolution as high as 0.″15. Our low-order CO observations delineate the cool molecular gas, the fuel for star formation in the systems, in unprecedented detail. For BRI 1202–0725, line emission is seen from both extreme starburst galaxies: the quasar host and the optically obscured submm galaxy (SMG), in addition to one of the Lyα emitting galaxies in the group. Line emission from the SMG shows an east–west extension of about 0.″6. For Lyα-2, the CO emission is detected at the same velocity as [C ii] and [N ii], indicating a total gas mass ∼4.0 × 1010
M
⊙. The CO emission from BRI 1335–0417 peaks at the nominal quasar position, with a prominent northern extension (∼1″, a possible tidal feature). The gas depletion timescales are ∼107 years for the three HyLIRGs, consistent with extreme starbursts, while that of Lyα-2 may be consistent with main sequence galaxies. We interpret these sources as major star formation episodes in the formation of massive galaxies and supermassive black holes via gas-rich mergers in the early universe.
