Periodismo de datos en Uruguay
Authors: Rodríguez Leandro 
Published: December 2016

El término periodismo de datos es un término nuevo que llegó a las redacciones hace algunos años, pero ahora ningún medio quiere quedar afuera. En un país pequeño como Uruguay —a pesar de que en todas las redacciones están al tanto de su existencia y ha habido algunas iniciativas— es una práctica que en el año 2015 todavía no ha encontrado su lugar en los medios. Este trabajo busca esclarecer de qué se habla cuando se habla de periodismo de datos para luego, a través de información recabada de medios, organizaciones no gubernamentales y centros educativos, averiguar cuál es su situación actual en el país, los impulsos que ha tenido, los obstáculos que ha encontrado y el futuro que le espera.

A Tessellation-Based Methodology for an Interactive Analysis of the Arctic Ice Dynamic Phenomenon with Spatial Online Analytical Processing

Published: December 2016

A tessellation-based methodology for interactively analyzing the spatio-temporal evolution of a dynamic phenomenon – ice coverage and its characteristics – using a spatial online analytical processing (OLAP) approach is proposed. The feasibility of the method was tested through a prototype developed in the context of the CanICE project using Canadian Ice Service data and the Egg Code, an international standard for characterizing sea and lake ice. By transforming the standard spatial OLAP vector-based point of view – aggregating data from instances of evolving features – into a tessellation-based point of view – aggregating data from constant spaces with evolving properties – the proposed solution makes it possible to meet the criteria of interactive multidimensional analysis for dynamic phenomena. The second innovative aspect of the methodology relates to the management of data quality with a spatial OLAP approach.
Éduquer les citoyens : corps, hygiène et santé à l'école mexicaine (1882–1913)
Authors: Moctezuma Lucia Martinez 
Published: December 2016

Cet article traite des discours sur le développement physique, intellectuel et moral du citoyen diffusés au Mexique à travers une série de dispositifs nationaux et étrangers tels que les congrès et les conférences. Comme le soulignait le médecin mexicain Manuel Uribe y Troncoso à propos du troisième Congrès international d'hygiène scolaire (Paris, 1910), ces événements sont des moments où les idées s'échangent et servent à comparer son pays aux autres. Au Mexique comme ailleurs, l'école représente l'institution idéale pour transmettre et faire aboutir un discours hygiénique de prévention des maladies et pour favoriser le développement d'une vie saine. Quelques propositions sont intégrées immédiatement lors des réunions pédagogiques, tandis que d'autres doivent être adaptées à la réalité d'un pays subissant des manques qui limitent en grande partie l'application de ces accords. Nous abordons ces discours à partir de deux grands axes permettant de suivre les discussions de ceux qui participent à ces rencontres où se construit une idée sur l'hygiène et la santé au bénéfice de l'enfant en école élémentaire, et d'analyser l'application de quelques-unes de ces propositions aux niveaux national et local.
Preoperative low level laser therapy in dogs undergoing tibial plateau levelling osteotomy: A blinded, prospective, randomized clinical trial
Authors: Rogatko Cleo , Tennant Rachel , Baltzer Wendy 
Published: December 2016

SummaryObjective: To evaluate the influence of pre-operative low-level laser therapy (LLLT) on therapeutic outcomes of dogs undergoing tibial plateau levelling osteotomy (TPLO).Methods: Healthy dogs undergoing TPLO were randomly assigned to receive either a single preoperative LLLT treatment (800–900 nm dual wavelength, 6 W, 3.5 J/cm2, 100 cm2 area) or a sham treatment. Lameness assessment and response to manipulation, as well as force plate analysis, were performed pre-operatively, then again at 24 hours, two weeks, and eight weeks postoperatively. Radiographic signs of healing of the osteotomy were assessed at eight weeks postoperatively.Results: Twenty-seven dogs (27 stifles) were included and no major complications occurred. At eight weeks postoperatively, a significant difference in peak vertical force analysis was noted between the LLLT (39.6% ± 4.7%) and sham groups (28.9% ± 2.6%), (p <0.01 Time, p <0.01 L). There were no significant differences noted between groups for all other parameters. The age of dogs in the LLLT group (6.6 ± 1.6 years) was greater than that for the sham group (4.5 ± 2.0, p <0.01). Although not significant, a greater proportion of LLLT dogs (5/8) had healed at the eight-week time point than in the sham group (3/12) despite the age difference (p = 0.11)Clinical significance: The results of this study demonstrate that improved peak vertical force could be related to the preoperative use of LLLT for dogs undergoing TPLO at eight weeks postoperatively. The use of LLLT may improve postoperative return to function following ca-nine osteotomies and its use is recommended.Supplementary Material to this article is available online at https://doi.org/10.3415/VCOT-15-12-0198.
Subjective attitudes and counterstance contingency
Authors: Kennedy Christopher , Willer Malte 
Published: December 2016

Across languages, SUBJECTIVE ATTITUDE VERBS (SAVs), such as English find, differ from ordinary doxastic attitude verbs (such as English believe) in that they require their complement to be subjective in a particular way. The goal of this paper is to develop a semantics for SAVs that predicts this fact but also captures the finer-grained differences between find-type SAVs and consider-type SAVs that make the former more restrictive than the latter. We propose that in terms of their core, at issue content, SAVs are just like believe in expressing a doxastic attitude towards the prejacent. They differ in that they introduce a presupposition that their prejacent is contingent with respect to a distinct set of discourse alternatives that we label COUNTERSTANCES: alternative common grounds that differ only in decisions about how to resolve semantic underdetermination. The larger theoretical significance of our proposal is that it supports a characterization of 'subjective language' as an essentially pragmatic, context-sensitive phenomenon, which does not correlate with semantic type (pace Sæbø) but derives from speakers' recognition of the possibility of counterstance.

ABSTRACT
We report our observations of very bright prompt optical and reverse shock (RS) optical emission of GRB 140512A and analyze its multi-wavelength data observed with the Swift and Fermi missions. It is found that the joint optical–X-ray–gamma-ray spectrum with our first optical detection (R = 13.09 mag) at

s during the second episode of the prompt gamma-rays can be fit by a single power law with an index of −1.32 ± 0.01. Our empirical fit to the afterglow light curves indicates that the observed bright optical afterglow with R = 13.00 mag at the peak time is consistent with predictions of the RS and forward shock (FS) emission of external shock models. A joint optical–X-ray afterglow spectrum is well fit with an absorbed single power law, with an index evolving with time from −1.86 ± 0.01 at the peak time to −1.57 ± 0.01 at a late epoch, which could be due to the evolution of the ratio of the RS to FS emission fluxes. We fit the light curves with standard external models, and derive the physical properties of the outflow. It is found that the ratio

is 8187, indicating a high magnetization degree in the RS region. Measuring the relative radiation efficiency with

, we have R
e = 0.02, implying that the radiation efficiency of the RS is much lower than that in FS. We also show that the R
B of GRBs 990123, 090102, and 130427A are similar to that of GRB 140512A and their apparent difference may be mainly attributed to the difference of the jet kinetic energy, initial Lorentz factor, and medium density among them.

ABSTRACT
Infrared variability is common among young stellar objects, with surveys finding daily to weekly fluctuations of a few tenths of a magnitude. Space-based observations can produce highly sampled infrared light curves, but are often limited to total baselines of about 1 month due to the orientation of the spacecraft. Here we present observations of the Chameleon I cluster, whose low declination makes it observable by the Spitzer
Space Telescope over a 200-day period. We observe 30 young stellar objects with a daily cadence to better sample variability on timescales of months. We find that such variability is common, occurring in ∼80% of the detected cluster members. The change in [3.6]–[4.5] color over 200 days for many of the sources falls between that expected for extinction and fluctuations in disk emission. With our high cadence and long baseline we can derive power spectral density curves covering two orders of magnitude in frequency and find significant power at low frequencies, up to the boundaries of our 200-day survey. Such long timescales are difficult to explain with variations driven by the interaction between the disk and stellar magnetic field, which has a dynamical timescale of days to weeks. The most likely explanation is either structural or temperature fluctuations spread throughout the inner ∼0.5 au of the disk, suggesting that the intrinsic dust structure is highly dynamic.
CH AS A MOLECULAR GAS TRACER AND C-SHOCK TRACER ACROSS A MOLECULAR CLOUD BOUNDARY IN TAURUS
Authors: Xu(许铎) Duo , Li(李菂) Di 
Published: December 2016

ABSTRACT
We present new observations of all three ground-state transitions of the methylidyne (CH) radical and all four ground-state transitions of the hydroxyl (OH) radical toward a sharp boundary region of the Taurus molecular cloud. These data were analyzed in conjunction with existing CO and dust images. The derived CH abundance is consistent with previous observations of translucent clouds (0.8 ≤ A

v
≤ 2.1 mag). The X(CH)-factor is nearly a constant (1.0 ± 0.06) × 1022 cm−2 K−1 km−1 s in this extinction range, with less dispersion than that of the more widely used molecular tracers CO and OH. CH turns out be a better tracer of total column density in such an intermediate extinction range than CO or OH. Compared with previous observations, CH is overabundant below 1 mag extinction. Such an overabundance of CH is consistent with the presence of a C-shock. CH has two kinematic components, one of which shifts from 5.3 to 6 km s−1, while the other stays at 6.8 km s−1 when moving from outside toward inside of the cloud. These velocity behaviors exactly match previous OH observation. The shifting of the two kinematic components indicates colliding streams or gas flow at the boundary region, which could be the cause of the C-shock.

ABSTRACT
In 2016 May, the intermediate polar FO Aqr was detected in a low state for the first time in its observational history. We report time-resolved photometry of the system during its initial recovery from this faint state. Our data, which includes high-speed photometry with cadences of just 2 s, show the existence of very strong periodicities at 22.5 and 11.26 minutes, equivalent to the spin–orbit beat frequency and twice its value, respectively. A pulse at the spin frequency is also present but at a much lower amplitude than is normally observed in the bright state. By comparing our power spectra with theoretical models, we infer that a substantial amount of accretion was stream-fed during our observations, in contrast to the disk-fed accretion that dominates the bright state. In addition, we find that FO Aqr’s rate of recovery has been unusually slow in comparison to rates of recovery seen in other magnetic cataclysmic variables, with an e-folding time of 115 ± 7 days. The recovery also shows irregular variations in the median brightness of as much as 0.2 mag over a 10-day span. Finally, we show that the arrival times of the spin pulses are dependent upon the system’s overall brightness.
ON THE PRESENCE OF TWO POPULATIONS OF SUNSPOTS
Authors: Nagovitsyn Yury A. , Pevtsov Alexei A. 
Published: December 2016

ABSTRACT
Using historical (1894–1976) and more modern (1977–2014) observations, we investigate statistical properties of distributions of sunspot areas and their long-term variations. We confirm the presence of two populations of sunspots with smaller and larger areas, and show that sunspot/group lifetime can be used to separate the two populations on small short-lived sunspot groups (SSG) and large long-lived groups (LLG). The area properties of LLG are nearly constant over the entire period of observations, while the SSGs show significant long-term variations. Based on the presence of long-term variations in one component and the absence of those in the other, we suggest that the production of two populations of sunspots (SSG and LLG) may be affected by different processes.

Published: December 2016

ABSTRACT
Although surveys of infall motions in dense cores have been carried out for years, few surveys have focused on mapping infall across cores using multiple spectral-line observations. To fill this gap, we present IRAM 30 m telescope maps of N2H+(1–0), DCO+(2–1), DCO+(3–2), and HCO+(3–2) emission toward two prestellar cores (L492 and L694-2) and one protostellar core (L1521F). We find that the measured infall velocity varies with position across each core and choice of molecular line, likely as a result of radial variations in core chemistry and dynamics. Line-of-sight infall speeds estimated from DCO+(2–1) line profiles can decrease by 40–50 m s−1 when observing at a radial offset

pc from the core's dust continuum emission peak. Median infall speeds calculated from all observed positions across a core can also vary by as much as 65 m s−1, depending on the transition. These results show that while single-pointing, single-transition surveys of core infall velocities may be good indicators of whether a core is either contracting or expanding, the magnitude of the velocities they measure are significantly impacted by the choice of molecular line, proximity to the core center, and core evolutionary state.
ON VARIATIONS OF PRE-SUPERNOVA MODEL PROPERTIES
Authors: Farmer R. , Fields C. E. , Petermann I. , Dessart Luc , Cantiello M. , Paxton B. , Timmes F. X. 
Published: December 2016

ABSTRACT
We explore the variation in single-star 15–30

, nonrotating, solar metallicity, pre-supernova MESA models that is due to changes in the number of isotopes in a fully coupled nuclear reaction network and adjustments in the mass resolution. Within this two-dimensional plane, we quantitatively detail the range of core masses at various stages of evolution, mass locations of the main nuclear burning shells, electron fraction profiles, mass fraction profiles, burning lifetimes, stellar lifetimes, and compactness parameter at core collapse for models with and without mass-loss. Up to carbon burning, we generally find that mass resolution has a larger impact on the variations than the number of isotopes, while the number of isotopes plays a more significant role in determining the span of the variations for neon, oxygen, and silicon burning. Choice of mass resolution dominates the variations in the structure of the intermediate convection zone and secondary convection zone during core and shell hydrogen burning, respectively, where we find that a minimum mass resolution of ≈0.01

is necessary to achieve convergence in the helium core mass at the ≈5% level. On the other hand, at the onset of core collapse, we find ≈30% variations in the central electron fraction and mass locations of the main nuclear burning shells, a minimum of ≈127 isotopes is needed to attain convergence of these values at the ≈10% level.

ABSTRACT
We present a high-sensitivity radio continuum survey at 6 and 1.3 cm using the Karl G. Jansky Very Large Array toward a sample of 58 high-mass star-forming regions. Our sample was chosen from dust clumps within infrared dark clouds with and without IR sources (CMC–IRs and CMCs, respectively), and hot molecular cores (HMCs), with no previous, or relatively weak radio continuum detection at the 1 mJy level. Due to the improvement in the continuum sensitivity of the Very Large Array, this survey achieved map rms levels of ∼3–10 μJy beam−1 at sub-arcsecond angular resolution. We extracted 70 continuum sources associated with 1.2 mm dust clumps. Most sources are weak, compact, and prime candidates for high-mass protostars. Detection rates of radio sources associated with the millimeter dust clumps for CMCs, CMC–IRs, and HMCs are 6%, 53%, and 100%, respectively. This result is consistent with increasing high-mass star formation activity from CMCs to HMCs. The radio sources located within HMCs and CMC–IRs occur close to the dust clump centers, with a median offset from it of 12,000 au and 4000 au, respectively. We calculated 5–25 GHz spectral indices using power-law fits and obtained a median value of 0.5 (i.e., flux increasing with frequency), suggestive of thermal emission from ionized jets. In this paper we describe the sample, observations, and detections. The analysis and discussion will be presented in Paper II.
ON THE ORIGIN OF C4H AND CH3OH IN PROTOSTELLAR ENVELOPES*
Authors: Lindberg Johan E. , Charnley Steven B. , Cordiner Martin A. 
Published: December 2016

ABSTRACT
The formation pathways of different types of organic molecules in protostellar envelopes and other regions of star formation are subjects of intense current interest. We present here observations of C4H and CH3OH, tracing two distinct groups of interstellar organic molecules, toward 16 protostars in the Ophiuchus and Corona Australis molecular clouds. Together with observations in the literature, we present C4H and CH3OH data from single-dish observations of 40 embedded protostars. We find no correlation between the C4H and CH3OH column densities in this large sample. Based on this lack of correlation, a difference in line profiles between C4H and CH3OH, and previous interferometric observations of similar sources, we propose that the emission from these two molecules is spatially separated, with the CH3OH tracing gas that has been transiently heated to high (∼70–100 K) temperatures and the C4H tracing the cooler large-scale envelope where CH4 molecules have been liberated from ices. These results provide insight in the differentiation between hot
corino and warm carbon-chain chemistry in embedded protostars.
Quelle « démocratie écologique » ?
Authors: Petit Victor , Guillaume Bertrand 
Published: December 2016

Il est possible de présenter la crise écologique sans parler de démocratie, comme il est possible de parler de la crise démocratique sans parler d’écologie. Ce papier vise au contraire à critiquer ce type d’approches et à questionner le lien entre « crise écologique » et « crise démocratique ». Ce lien s’est récemment cristallisé en France autour des propositions de « démocratie écologique » de Dominique Bourg et Kenny Whiteside, qui ont été largement débattues. Nous en résumerons ici certains éléments centraux pour apporter une autre vision d’une « démocratie écologique », moins institutionnelle, et plus politique, que nous résumons sous l’appellation de « démocratie des communs ».
