Abstract
We present a near-infrared spectral sequence of the electromagnetic counterpart to the binary neutron star merger GW170817 detected by Advanced Laser Interferometer Gravitational-wave Observatory (LIGO)/Virgo. Our data set comprises seven epochs of J+H spectra taken with FLAMINGOS-2 on Gemini-South between 1.5 and 10.5 days after the merger. In the initial epoch, the spectrum is dominated by a smooth blue continuum due to a high-velocity, lanthanide-poor blue kilonova component. Starting the following night, all of the subsequent spectra instead show features that are similar to those predicted in model spectra of material with a high concentration of lanthanides, including spectral peaks near 1.07 and 1.55 μm. Our fiducial model with 0.04 M
⊙ of ejecta, an ejection velocity of v = 0.1c, and a lanthanide concentration of X
lan = 10−2 provides a good match to the spectra taken in the first five days, although it over-predicts the late-time fluxes. We also explore models with multiple fitting components, in each case finding that a significant abundance of lanthanide elements is necessary to match the broad spectral peaks that we observe starting at 2.5 days after the merger. These data provide direct evidence that binary neutron star mergers are significant production sites of even the heaviest r-process elements.

Abstract
The merging neutron star gravitational-wave event GW170817 has been observed throughout the entire electromagnetic spectrum from radio waves to γ-rays. The resulting energetics, variability, and light curves are shown to be consistent with GW170817 originating from the merger of two neutron stars, in all likelihood followed by the prompt gravitational collapse of the massive remnant. The available γ-ray, X-ray, and radio data provide a clear probe for the nature of the relativistic ejecta and the non-thermal processes occurring within, while the ultraviolet, optical, and infrared emission are shown to probe material torn during the merger and subsequently heated by the decay of freshly synthesized r-process material. The simplest hypothesis, that the non-thermal emission is due to a low-luminosity short γ-ray burst (sGRB), seems to agree with the present data. While low-luminosity sGRBs might be common, we show here that the collective prompt and multi-wavelength observations are also consistent with a typical, powerful sGRB seen off-axis. Detailed follow-up observations are thus essential before we can place stringent constraints on the nature of the relativistic ejecta in GW170817.
Video Feedback and 2-Dimensional Landing Kinematics in Elite Female Handball Players
Authors: Benjaminse Anne , Postma Wytze , Janssen Ina , Otten Egbert 
Published: October 2017

Context:
In team handball, an anterior cruciate ligament injury often occurs during landing after a jump shot. Many intervention programs try to reduce the injury rate by instructing athletes to land more safely. Video is an effective way to provide feedback, but little is known about its influence on landing technique in sport-specific situations.

Objective:
To test the effectiveness of a video-overlay feedback method on landing technique in elite handball players.

Design:
Controlled laboratory study.

Setting:
Laboratory.

Patients or Other Participants:
A total of 16 elite female handball players assigned to a control group (n = 8; age = 17.61 ± 1.34 years, height = 1.73 ± 0.06 m, mass = 69.55 ± 4.29 kg) or video group (n = 8; age = 17.81 ± 0.86 years, height = 1.71 ± 0.03 m, mass = 64.28 ± 6.29 kg).

Intervention(s):
Both groups performed jump shots in a pretest, 2 training sessions, and a posttest. The video group received video feedback of an expert model with an overlay of their own jump shots in training sessions 1 and 2, whereas the control group did not.

Main Outcome Measure(s):
We measured ankle, knee, and hip angles in the sagittal plane at initial contact and peak flexion; range of motion; and Landing Error Scoring System (LESS) scores. One 2 × 4 repeated-measures analysis of variance was conducted to analyze the group, time, and interaction effects of all kinematic outcome measures and the LESS score.

Results:
The video group improved knee and hip flexion at initial contact and peak flexion and range of motion. In addition, the group's average peak ankle flexion (12.0° at pretest to 21.8° at posttest) and LESS score (8.1 pretest to 4.0 posttest) improved. When we considered performance variables, no differences between groups were found in shot accuracy or vertical jump height, whereas horizontal jump distance in the video group increased over time.

Conclusions:
Overlay visual feedback is an effective method for improving landing kinematics during a sport-specific jump shot. Further research is warranted to determine the long-term effects and transfer to training and game situations.
Seismic monitoring of small alpine rockfalls – validity, precision and limitations

Published: October 2017

Abstract. Rockfall in deglaciated mountain valleys is perhaps the most important post-glacial geomorphic process for determining the rates and patterns of valley wall erosion. Furthermore, rockfall poses a significant hazard to inhabitants and motivates monitoring efforts in populated areas. Traditional rockfall detection methods, such as aerial photography and terrestrial laser scanning (TLS) data evaluation, provide constraints on the location and released volume of rock but have limitations due to significant time lags or integration times between surveys, and deliver limited information on rockfall triggering mechanisms and the dynamics of individual events. Environmental seismology, the study of seismic signals emitted by processes at the Earth's surface, provides a complementary solution to these shortcomings. However, this approach is predominantly limited by the strength of the signals emitted by a source and their transformation and attenuation towards receivers. To test the ability of seismic methods to identify and locate small rockfalls, and to characterise their dynamics, we surveyed a 2.16 km2 large, near-vertical cliff section of the Lauterbrunnen Valley in the Swiss Alps with a TLS device and six broadband seismometers. During 37 days in autumn 2014, 10 TLS-detected rockfalls with volumes ranging from 0.053 ± 0.004 to 2.338 ± 0.085 m3 were independently detected and located by the seismic approach, with a deviation of 81−29+59 m (about 7 % of the average inter-station distance of the seismometer network). Further potential rockfalls were detected outside the TLS-surveyed cliff area. The onset of individual events can be determined within a few milliseconds, and their dynamics can be resolved into distinct phases, such as detachment, free fall, intermittent impact, fragmentation, arrival at the talus slope and subsequent slope activity. The small rockfall volumes in this area require significant supervision during data processing: 2175 initially picked potential events reduced to 511 potential events after applying automatic rejection criteria. The 511 events needed to be inspected manually to reveal 19 short earthquakes and 37 potential rockfalls, including the 10 TLS-detected events. Rockfall volume does not show a relationship with released seismic energy or peak amplitude at this spatial scale due to the dominance of other, process-inherent factors, such as fall height, degree of fragmentation, and subsequent talus slope activity. The combination of TLS and environmental seismology provides, despite the significant amount of manual data processing, a detailed validation of seismic detection of small volume rockfalls, and revealed unprecedented temporal, spatial and geometric details about rockfalls in steep mountainous terrain.

Authors: Comeras Angel B. , Raposo Javier F. , De Luxan Margarita 
Published: October 2017

Las personas con discapacidad intelectual, grado de discapacidad leve y mayores de edad, utilizan expresiones artísticas como vehículo de expresión, comunicación y adaptación cultural. Los significativos cambios producidos hacia concepciones de la discapacidad intelectual más dinámicas, basadas en mayores interacciones, de la discapacidad intelectual, han conducido hacia la promoción de actividades artísticas y sensoriales con positivos resultados perceptivos y de comunicación. Se han realizado prácticas durante cinco años, entre estudiantes de Arquitectura, estudiantes de otras áreas de conocimiento (Farmacia, Enfermería, Fisioterapia y Comunicación) y personas con discapacidad intelectual, sobre aspectos cognitivos, sensoriales y sociales, donde han sido contrastadas y asumidas diversas percepciones artísticas, para expresar algunas dificultades en el uso de los entornos construidos. La implementación, de algunas percepciones artísticas asumidas, en estrategias cognitivas de generación arquitectónica es beneficiosa para el uso de edificios destinados a personas con discapacidad intelectual. Se aportan y describen dos ejemplos reales de edificios donde han sido aplicadas, en sus inicios proyectuales, plasmaciones artísticas conocidas que han producido un aumento en su comprensión y reconocimiento espacial, transcurrido un tiempo mayor de diez años como usuarios.

Published: October 2017

<p>Desde o período das Grandes Navegações, mais precisamente nos séculos XV e XVI, procura-se uma maneira mais rápida de ligar a Europa, Ásia e América. Nessa procura muitos exploradores se aventuraram no Ártico, porém naquela época, as condições climáticas eram diferentes das atuais, sendo que o gelo marinho cobria quase toda extensão do Oceano Ártico mesmo no verão. Assim, as rotas marítimas árticas não puderam ser exploradas por muito tempo. Entretanto, com o atual aquecimento no Ártico e a consequente retração do gelo marinho, o que era um sonho passa a ser realidade: as rotas que outrora foram abandonadas por serem de difícil acesso, passam a ligar o mundo de maneira mais rápida e barata. Neste artigo examina a procura por essas rotas em artigos científicos e em livros que relatam registros históricos e qual é a expectativa para o século XXI.</p><p><strong>Palavras–chave:</strong> Rota Nordeste, Rota Noroeste, Ártico.</p><p><strong>Abstract </strong></p><p>Since the Great Navigations period, 15th and 16th centuries, there has been a search for faster sea-lanes to connect Europe, Asia and America.

Presently, the Arctic warming and the consequent decline of sea ice cover area, make such routes a reality and could potentially connect the world more quickly and cheaply.

Restricted and Repetitive Behaviour in Persons with Autism (Ages 0-18): An Integrative Review of Treatment Related to Occupational Therapy
Authors: Patriquin Melissa , MacKenzie Diane , Versnel Joan 
Published: October 2017

Objective: To identify evidence-based behavioural interventions used to decrease restricted and repetitive behaviour (RRB) in children with autism (ages 0-18); to understand the application of these strategies within the PEO (Person, Environment, Occupation) Model of Occupational Performance and the role of the occupational therapist in addressing this limitation.
Background: RRB is a core feature of autism that often impedes functional behaviour. Decreasing RRB to enable functional behaviours is central to the occupational therapist’s role with this population. Many interventions identified as effective for this impairment are based on the principles of applied behaviour analysis (ABA).
Method: An integrative review of the literature was completed to identify interventions targeting RRBs. Those found to be effective are described within an ABA framework and within the PEO Model of Occupational Performance.
Results: This review identified twenty-eight effective interventions used to treat RRBs in autism relevant to the field of occupational therapy. Categorization of interventions using an ABA framework and the PEO Model allowed comparison between approaches and application to occupational therapy practice.
Conclusion: A functional behaviour approach (FBA) used in combination with the PEO model will enable greater understanding of RRBs and provide a more comprehensive approach to the treatment of RRBs in children with autism.

Cet article analyse une démarche de caractérisation des communautés locales visant à « mieux connaître pour mieux agir » avec ces communautés. Issu de la santé publique, le dispositif original (Boisvert, 2007) propose une série d’opérations s’appuyant sur l’idée qu’une bonne connaissance des forces, des faiblesses et du potentiel de la communauté constitue un facteur de succès de son développement. L’étude dont il est question ici cherchait à montrer si le dispositif contribue au développement des communautés. Le cadre conceptuel était structuré autour des étapes de la démarche et de principes fondateurs du développement des communautés (intersectorialité,empowerment, participation citoyenne). L’évaluation a été menée dans trois régions du Québec, puis doublée d’une analyse transversale.

An Empirical Model of Titan's Magnetic Environment During the Cassini Era: Evidence for Seasonal Variability
Authors: Kabanovic Slawa , Simon Sven , Neubauer Fritz M. , Meeks Zachary 
Published: October 2017

AbstractBased on the magnetic field data collected during the Cassini era, we construct an empirical model of the ambient magnetospheric field conditions along the orbit of Saturn's largest moon Titan. Observations from Cassini's close Titan flybys as well as 191 nontargeted crossings of Titan's orbit are taken into account. For each of these events we apply the classification technique of Simon et al. (2010b) to categorize the ambient magnetospheric field as current sheet, lobe‐like, magnetosheath, or an admixture of these regimes. Independent of Saturnian season, Titan's magnetic environment around noon Saturn local time is dominated by the perturbed fields of Saturn's broad magnetodisk current sheet. Only observations from the nightside magnetosphere reveal a slow but steady change of the background field from southern lobe‐type to northern lobe‐type on a timescale of several years. This behavior is consistent with a continuous change in the curvature of the bowl‐shaped magnetodisk current sheet over the course of the Saturnian year. We determine the occurrence rate of each magnetic environment category along Titan's orbit as a function of Saturnian season and local time.

AbstractSecondary electrons are continuously generated via photoemission from sunlit spacecraft and instrument surfaces. These particles can subsequently contaminate low‐energy channels of electron sensors. Spacecraft photoelectrons are measured at energies below that of a positive spacecraft potential and can be removed at the expense of energy resolution. However, fluxes of photoelectrons generated inside electron instruments are independent of spacecraft potential and must be fully characterized in order to correct electron data. Here we present observations of spacecraft and instrument photoelectron populations measured with the Dual Electron Spectrometers (DES) on NASA's Magnetospheric Multiscale (MMS) mission. We leverage observations from Earth's nightside plasma sheet taken during MMS commissioning and develop an empirical model of instrument photoelectrons. This model is used with DES velocity distribution functions to correct plasma moments and has been made publicly available on the MMS science data center for use by the scientific community.
