The Quasar-frame Velocity Distribution of Narrow CIV Absorbers

We report on a survey for narrow (FWHM < 600 km/s) CIV absorption lines in a sample of bright quasars at redshifts $1.8 \le z < 2.25$ in the Sloan Digital Sky Survey. Our main goal is to understand the relationship of narrow CIV absorbers to quasar outflows and, more generally, to quasar environments. We determine velocity zero-points using the broad MgII emission line, and then measure the absorbers' quasar-frame velocity distribution. We examine the distribution of lines arising in quasar outflows by subtracting model fits to the contributions from cosmologically intervening absorbers and absorption due to the quasar host galaxy or cluster environment. We find a substantial number ($\ge 43\pm6$ per cent) of absorbers with REW $> 0.3$ \AA in the velocity range +750 km/s \la v \la +12000 km/s are intrinsic to the AGN outflow. This `outflow fraction' peaks near $v=+2000$ km/s with a value of $f_{outflow} \simeq 0.81 \pm 0.13$. At velocities below $v \approx +2000$ km/s the incidence of outflowing systems drops, possibly due to geometric effects or to the over-ionization of gas that is nearer the accretion disk. Furthermore, we find that outflow-absorbers are on average broader and stronger than cosmologically-intervening systems. Finally, we find that $\sim 14$ per cent of the quasars in our sample exhibit narrow, outflowing CIV absorption with REW $> 0.3$\AA, slightly larger than that for broad absorption line systems.Comment: 11 pages, 9 figures, accepted for publication in MNRA

Health Digital Inclusion and Patient-centered Care Readiness in the USA

Patient-centered care is a relatively new form of healthcare that empowers people when they receive services, but patients must get ready for the active roles they are going to play in order to participate. Based on a literature review, this study conceptualizes that patient-centered care readiness has two basic capabilities: (1) health information access and (2) coordination and communication. The development of these capabilities, leading to the ultimate objective of patient choice and empowerment, depends on the status of health digital inclusion. To maximize the benefits of patient-centered care and reduce the risk of health disparity, it is necessary to assess the patient-centered care readiness of a population, especially to find out who is at a disadvantage. Using the 2009 U.S. National Health Interview Survey data, this study conducts logistic regression and classification tree analyses to predict the two capabilities with eleven physiological, population, socioeconomic, and healthcare-related variables. The results suggest that there is an uneven development of patient-centered care readiness in the country, especially for those who are socially and economically disadvantaged, such as minority people and senior citizens. The findings provide researchers and practitioners the insights on how to cross the gap and prepare the whole nation for the transition

Contrôle des frontières

Le renforcement de la frontière entre les États-Unis et le Mexique a un effet direct sur ceux qui tentent de la franchir. Face un passage rendu de plus en plus difficile, les migrants n'ont d'autre choix que de traverser des zones dangereuses. Pour contourner cette politique de dissuasion, ils risquent leur vie. La police des frontières américaine est en première ligne de ce dispositif. Derrière, c'est toute une bureaucratie qui semble rester sourde aux conséquences tragiques de sa politique migratoire

Simulating CALUMA (CAssino Low-Cost hUMAnoid) Robot Carrying a Load

In this paper, the operation of CALUMA (CAssino Low-cost hUMAnoid) robot has been investigated for a task while carrying a load. CALUMA robot is the result of a design project that has been elaborated for designing and building a low-cost easy-operation humanoid robot by summarizing experiences and prototypes that have been developed at LARM. Dynamic simulations have been computed by using ADAMS software in order to study dynamical aspects of CALUMA operation while carrying a load. The dynamic simulations have also been used for studying the manipulation performance of CALUMA robot. Simulations have given results that confirm the feasibility of the proposed design, as shown in the reported examples

La represión franquista en Canarias durante la Guerra Civil (1936-1939): Un estado de la cuestión

El objetivo de este trabajo es ofrecer una visión de conjunto de lo que supuso la represión franquista en las islas Canarias durante el periodo de duración de la Guerra Civil a través del análisis de la bibliografía que se ha publicado a lo largo de los últimos años en torno a este fenómeno. Con esta bibliografía como base trataremos de mostrar cómo la autoridad sublevada comienza a asegurar inmediatamente lo que será un territorio de retaguardia durante toda la duración de la guerra y los métodos que utilizó para esto, así como los ámbitos y grupos sociales que sufrieron dicha represión en mayor medida o que participaron en ella. Trataremos también de mostrar algunas diferencias entre las islas en cuanto al volumen, severidad y aplicación de esta política de control a través del miedo, así como los motivos de estas diferencias.The aim of this paper is to offer a broad perspective of what the francoist repression meant for the Canary Islands throughout the duration of the Spanish Civil War through the analysis of the bibliography that has been published in the last years around this phenomenon. With this bibliography as a starting point, we will try to show how the revolted authorities immediately started to secure what would be a rear-guard territory for all the duration of the war and the methods it used for this purpose, as well as the social spheres and groups that suffered the most under these measures or that collaborated with them. We will also try to show some of the differences in volume, severity and enforcement of these policies of public control through fear between the different islands and the reasons behind this difference

Macroscale abundance patterns of hydromedusae in the temperate Southwestern Atlantic (27º-56º S)

Gelatinous organisms are crucial components of marine ecosystems and some species imply social and economic consequences. However, certain geographic areas, such as the temperate Southwestern Atlantic (SWA, 27 - 56 S), remain understudied in terms of jellyfish ecological data. We analyzed 3,727 plankton samples collected along ~6.7 million km2 over a 31-year period (1983–2014) to determine the occurrence, abundance, and diversity patterns of hydromedusae in the SWA. Analyses were made at both community and species levels. Two abundance hot spots of hydromedusae were identified, where values up to 2,480 ind. m-3 were recorded between 2003 and 2014. Liriope tetraphylla and Obelia spp. were the main responsible for recurrent peaks. Diversity indexes were in the range of those published for temperate areas worldwide, and some coastal zones showed values that can be considered moderate to high for a temperate neritic region. The community analysis yielded 10 groups following previously determined biogeographic schemes throughout the study area. This work enhances the knowledge of hydromedusae in the SWA and provides essential information about the current global warming context and the gelatinous zooplankton data necessity.Fil: Dutto, María Sofía.
