A New Multi-Method Well Placement Approach In Optimizing a Challenging Thin Reservoir Well Injectivity
Authors: Bazara Magdi , Khalil Dia , Al-Zarafi Alaa , Al Abri Abdelrazzaq , Farah Ahmed , Al Busaidi Adil
Published: March 2018

This case study is done on a mature oil field. In this field, a thin dolomitic layer is thought to be acting as a baffle of water injector in the field. As this thin layer is less than 50 cm thick and not consistently recognizable using some conventional logs, this is a trial of using a combination of advance distance to boundary detection and ultra-high-resolution imaging tool to steer the well above this thin layer. Based on core available data, it is a dolomitized Redstone with a strong hydrocarbon stain. The tight, relative dolomite is likely to act as a baffle to vertical fluid flow. To enhance the effect of planned water injection project, placement of horizontal well just above the dolomitic layer by a meter or a meter and a half was the target for a successfully injector well in this field. Challenges to the landing of such a well includes depth, thickness, and dip uncertainties. Additionally, there are the errors that are inherent to correlating between the reservoir scale and the seismic scale. Finally, it is difficult to discern boundaries in this low-resistivity environment characterized by very low resistivity contrast. Resistivity contrast, in particular, is of major importance as it plays the main role in determining the operability of common distance-to-boundary tools.

Combination of distance to boundary detection capability and Ultra-High Resolution Imaging while drilling allowed to place wellbore precisely at certain distance from the dolomitic fluid barrier, avoid any unwanted exits and to evaluate this dolomitic layer properties by resistivity, density/neutron data known as triple-combo sideways with the above mentioned used technology for steering. The data provided were integrated with seismic surveys to refine the reservoir structure and geometry interpretation. The improved understanding made it possible to optimize recovery and production through optimum landing of the well and to map the overlying and underlying reservoir parameters.

By selecting the right tool configurations in the bottom-hole assembly (BHA), formation tops were detected from a distance of up to 2m true vertical thickness (TVT) and in the same time parallel to the dolomitic layer in most of the well trajectory. Resistivity contrast was as low as 0.3 ohm.m versus the 0.9 ohm.m when detecting the dolomitic layer marker unit. On the other hand, in some areas of the well, crossing the dolomitic layer and a one bouncing to it was needed to build the confidence in this method and confirming the steering interpretation for the future upcoming wells in the same field.

Published: March 2018

Reexpansion pulmonary edema (RPE) is an uncommon complication of thoracentesis or chest drainage. It occurs in the ipsilateral or contralateral lung. Causes, pathogenesis and therapy are not well understood especially for contralateral RPE. We describe a case of fatal contralateral RPE in a 59-years-old woman with right lung cancer underwent ultrasound-guided thoracentesis for massive pleural effusion and severe dyspnea. Pathogenesis of contralateral RPE is probably multifactorial and in this case is mostly due to the overperfusion of the healthy lung and consequent capillary damage. The right therapy for this condition is not known.

Abstract. The effect of acidity and relative humidity on bulk isoprene aerosol parameters has been investigated in several studies, however few measurements have been conducted on individual aerosol compounds. While the focus of this study has been the examination of the effect of acidity and RH on secondary organic aerosol (SOA) chemical composition from isoprene photooxidation in the presence of NOx, a detailed characterization of SOA at the molecular level have been also conducted. Experiments were conducted in a 14.5 m3 smog chamber operated in flow mode. Based on a detailed analysis of mass spectra obtained from GCMS of silylated derivatives in EI and CI modes, and UPLC/ESI/QTOF HRMS, and collision-induced dissociation in the positive and negative ionization modes, we characterized not only typical isoprene products, but also new oxygenated compounds. The analysis showed the presence of methylthreonic acids (mTr) and methyltartaric acids (mTA), proposed recently by our groups as isoprene aging SOA markers. Furthermore, a series of organosulfates (OSs) were tentatively identified including 2mTr-OS, 2mTA-OS and 2mTA nitroxy-OS. Under acidic conditions, the major identified compounds include 2-methyltetrols (2mT), 2-methylglyceric acid (2mGA) and 2mT-OS. Other products identified include epoxydiols, mono- and dicarboxylic acids, OSs, and nitroxy- and nitrosoxy-OSs. The contribution of SOA products from isoprene oxidation to PM2.5 was investigated by analyzing ambient aerosol collected at rural sites in Poland. mTs, mGA and several organosulfates and nitroxy-OS were detected in both the field and laboratory samples. The influence of RH on SOA formation was modest in non-acidic seed experiments. Total SOC decreased with increasing RH. The yields of most compounds decreased, but the concentrations of 2mTA, IEPOX-OS, 2mGA-OS and 2mTr-OS increased with increasing RH. Some components followed this pattern while other were more abundant in non-acidic experiments or behaved in a mixed way, depending on RH.

Published: March 2018

Abstract. Understanding wet avalanche intensity and the role of past environmental changes on wet avalanche occurrence is a main concern especially in the context of a warming climate and accelerated environmental mutations. Avalanches are closely related to fast cryosphere changes and may cause major threats to human society. Here, we used the sedimentary archive of the alpine Lake Lauvitel (western French Alps) to establish the first long-term avalanche record in this Alpine region. For this purpose, we used a novel CT scan methodology that allows the precise identification of coarse material – from sand to pebble – transported to the lake and embedded within the finer continuous sedimentation. We identified a total of 166 deposits over the last 3300 yrs cal. BP. In parallel, a detailed pollen analysis gave an independent record of environmental changes. Based on modern observation, lake monitoring, seismic investigations and sedimentological evidences, coarse material deposits were attributed to wet avalanche events. Our results highlight the effect of vegetation cover on the avalanche hazard while a period of strong frequency increase occurred after 780 yrs cal. BP. In Lake Lauvitel, this period corresponds to a major forest clearance induced by the rise of human land-use. Climate forcing on the avalanche hazard was investigated before and after the vegetation shift. On a multi-centennial scale, wet avalanches preferably occur during periods of larger glacier extent, in which higher winter precipitations probably generate a sufficiently thick snow cover. On a sub-centennial scale, avalanches are more frequent during periods of relative warming, resulting in a destabilisation of the same snow cover in spring season. Our results highlight as well the role of forest cover to mitigate wet snow avalanches occurrence. In the context of predicted warmer temperatures, this study raises the question of whether a wet avalanche hazard increase may be expected in the near future especially at higher altitudes.
Global drought and severe drought-affected populations in 1.5 and 2 °C warmer worlds
Authors: Liu Wenbin , Sun Fubao , Lim Wee Ho , Zhang Jie , Wang Hong , Shiogama Hideo , Zhang Yuqing
Published: March 2018

Abstract. The 2015 Paris Agreement proposed a more ambitious climate change
mitigation target on limiting global warming to 1.5 ∘C instead of
2 ∘C above preindustrial levels. Scientific investigations on
environmental risks associated with these warming targets are necessary to
inform climate policymaking. Based on the Coupled Model
Intercomparison Project phase 5 (CMIP5) climate models, we present the first risk-based
assessment of changes in global drought and the impact of severe drought on
populations from additional 1.5 and 2 ∘C warming conditions. Our
results highlight the risk of drought on a global scale and in several hotspot
regions such as the Amazon, northeastern Brazil, southern Africa and Central Europe
at both 1.5 and 2 ∘C global warming relative to the historical
period, showing increases in drought durations from 2.9 to 3.2 months. Correspondingly, more total and urban populations would be exposed to
severe droughts globally (+132.5 ± 216.2 million and
+194.5 ± 276.5 million total population and +350.2 ± 158.8 million
and +410.7 ± 213.5 million urban populations in 1.5 and
2 ∘C warmer worlds) and regionally (e.g., East Africa, West
Africa and South Asia). Less rural populations (−217.7 ± 79.2 million
and −216.2 ± 82.4 million rural populations in 1.5 and 2 ∘C
warmer worlds) would be exposed to severe drought globally under
climate warming, population growth and especially the urbanization-induced
population migration. By keeping global warming at 1.5 ∘C above the
preindustrial levels instead of 2 ∘C, there is a decrease in drought risks
(i.e., less drought duration, less drought intensity and severity but
relatively more frequent drought) and the affected total, urban and
rural populations would decrease globally and in most regions. While
challenging for both East Africa and South Asia, the benefits of limiting
warming to below 1.5 ∘C in terms of global drought risk and impact
reduction are significant.
Long Island Sound Temperature Variability and its Associations with the Ridge-trough Dipole and Tropical Modes of Sea Surface Temperature Variability
Authors: Schulte Justin A. , Lee Sukyoung
Published: March 2018

Abstract. Possible mechanisms behind the longevity of intense Long Island Sound (LIS) water temperature events are examined using an event-based approach. By decomposing a LIS surface water temperature time series into negative and positive events, it is revealed that the most intense LIS water temperature event in the 1979–2013 period occurred around 2012, coinciding with the 2012 ocean heat wave across the mid-Atlantic Bight. The LIS events are related to a ridge-trough dipole pattern whose strength and evolution can be measured using a dipole index. The dipole index was shown to be strongly correlated with LIS water temperature anomalies, explaining close to 64 % of cool-season LIS water temperature variability. Consistently, a major dipole pattern event coincided with the intense 2012 LIS warm event. A composite analysis revealed that long-lived intense LIS water temperature events are associated with tropical sea surface temperature (SST) patterns. The onset and mature phases of LIS cold events were shown to coincide with central Pacific El Niño events, whereas the termination of LIS cold events was shown to possibly coincide with canonical El Niño events or El Niño events that are a mixture of eastern and central Pacific El Niño flavors. The mature phase of LIS warm events was shown to be associated with negative SST anomalies across the central equatorial Pacific, though the results were not found to be robust. The dipole pattern was also shown to be related to tropical SST patterns and fluctuations in central Pacific SST anomalies were shown to evolve coherently with the dipole pattern and the strongly related East Pacific/North Pacific pattern on decadal time scales. The results from this study have important implications for seasonal and decadal prediction of the LIS thermal system.
Four decades of surface elevation change of the Antarctic Ice Sheet
from multi-mission satellite altimetry
Authors: Schröder Ludwig , Horwath Martin , Dietrich Reinhard , Helm Veit
Published: March 2018

Abstract. We developed an approach for a multi-mission satellite altimetry analysis over the Antarctic Ice Sheet which comprises Seasat, Geosat, ERS-1, ERS-2, Envisat, ICESat and CryoSat-2. In a first step we apply a consistent reprocessing of the radar alitmetry data which improves the measurement precision by up to 50 %. We then perform a joint repeat altimetry analysis of all missions. We estimate inter-mission offsets by approaches adapted to the temporal overlap or non-overlap and to the similarity or dissimilarity of involved altimetry techniques. Hence, we obtain monthly grids forming a combined surface elevation change time series. Owing to the early missions Seasat and Geosat, the time series span almost four decades from 07/1978 to 12/2017 over 25 % of the ice sheet area (coastal regions of East Antarctica and the Antarctic Peninsula). Since the launch of ERS-1 79 % of the ice sheet area is covered by observations. Over this area, we obtain a negative volume trend of −34 ± 5 km3 yr−1 for the more than 25-year period (04/1992–12/2017). These volume losses have significantly accelerated to a rate of −170 ± 11 km3 yr−1 for 2010–2017. Interannual variations significantly impact decadal volume rates which highlights the importance of the long-term time series. Our time series show a high coincidence with modeled cumulated precipitation anomalies and with satellite gravimetry. This supports the interpretation with respect to snowfall anomalies or dynamic thinning. Moreover, the correlation with cumulated precipitation anomalies back to the Seasat and Geosat periods highlights that the inter-mission offsets were successfully corrected and that the early missions add valuable information.
Transgressive Desire in Chaucer's Legend of Thisbe
Authors: Allen-Goss Lucy
Published: March 2018

Chaucer's Legend of Good Women is famous for its proposal to celebrate “good” women and expose faithless men, carried out through the rewriting of classical women's stories in ways that truncate unlikely figures into suspiciously anodyne passivity. Yet his tale of Pyramus and Thisbe has seemed to preclude even this possibility, for the original version depicts innocent and devoted lovers, and such subtext as has been found has been widely dismissed as merely comical. However, this ignores the narrative's established potential as an exemplum of the relationships between desire, grammar, and interpretation. For Chaucer, startling innuendos that cast Pyramus as a hapless, feminized misreader and Thisbe as his queerly authoritative lover also prepare for serious interrogation of the patristic tradition of gendered hermeneutics.
“Something Came Over Him”: Narratives on Being “Carried by Witches” and Their Possible Connection to Altered States of Consciousness
Authors: Mencej Mirjam
Published: March 2018

The article discusses the experience of being “carried by witches” narrated to me repeatedly during my field research in rural eastern Slovenia in 2000–2001. The experience, which was ascribed to the agency of witches who “enchanted” their victims and led them astray, typically occurred in the forest at night and implied disorientation, sometimes (but not necessarily) the vision of light(s) that people followed or were drawn to, and a shift of consciousness. The article argues that particular neurological conditions (out-of-body experiences, near-death experiences) may have provided a basis for the experience of at least some of the subjects in the memorates, and that various cultural concepts explaining the experience, and cultural patterns of structuring narratives about it, may have been adopted by people in order to cope with and make sense of what they experienced in a society that does not grant cultural value to altered states of consciousness.
Impacto de políticas de vivienda en acceso al hábitat urbano en Córdoba, Argentina
Authors: Boccolini Sara María
Published: March 2018

Se analizó el impacto de las políticas de producción de vivienda social en las estrategias de acceso a la vivienda urbana en Córdoba, Argentina, entre 2001 y 2015, verificando que estas normativas fomentan procesos de contraurbanización, periurbanización, inquilinización, y el vaciamiento de áreas pericentrales e intermedias.

Se analizaron las políticas públicas de producción directa e indirecta (financiamiento) de vivienda urbana, sistematizando información obtenida en entrevistas a actores clave, datos censales, resultados de investigaciones indexadas locales y regionales en torno al tema, e informes realizados por instituciones públicas y privadas, para reconstruir el alcance de estas políticas para resolver el déficit habitacional, su disponibilidad para distintos grupos socioeconómicos y los patrones de territorialización que emergen de ellas. Los resultados se plantearon como aporte en la discusión actual acerca de la producción de hábitat urbano en áreas metropolitanas de Argentina y Latinoamérica.
Alternativa para recuperación de espacio público mediante infraestructuras verdes en Tunja (Colombia)
Authors: Quintero González Laura Estefanía
Published: March 2018

La explosión demográfica global actual ha traído consigo el crecimiento desmedido de las ciudades, con áreas urbanas que se expanden, invadiendo zonas de importancia ambiental y, con ello, reduciendo la posibilidad de espacios públicos de calidad. Tunja es una de las ciudades en crecimiento de Colombia y su zona centro necesita una alternativa de recuperación y generación de espacios verdes públicos para evitar futuros fenómenos de densificación. La investigación tiene dos propósitos: determinar la disponibilidad del espacio público existente en el área urbana de la ciudad de Tunja mediante una caracterización y diagnóstico de disponibilidad; y, con ello, formular tipos específicos de infraestructuras verdes. Dadas las regulares condiciones de estado de la red de espacio público existente y la desigualdad en la conectividad espacial de los lugares dentro del sistema, se plantean tipos de infraestructuras vegetadas para su instalación en los lugares existentes y en los potencialmente nuevos.
Asignación Universal por Hijo y los roles de género
Authors: Bonavitta Paola
Published: March 2018

En las últimas décadas, en América Latina en general y Argentina, en particular, “la cuestión social” sufrió un fuerte desplazamiento. De conformar un análisis global del sistema, en términos de explotación, reparto, etc., pasó a constituir un enfoque centrado en el segmento más vulnerable de la población. En Argentina, entre 2009 y 2015, el Estado generó una serie de medidas y de políticas asistencialistas de carácter universal que señalaron a la seguridad social como un vector inclusivo central a partir del enfoque de derechos. Algunas políticas públicas destinadas a paliar la condición de pobreza se dirigen, mayoritariamente, a las mujeres por ser quienes más tiempo están en el hogar, con las familias y los hijos y por ser consideradas más responsables en los gastos y cuidados. Esto termina mejorando la situación de pobreza en el corto plazo pero no genera estrategias de cambio a futuro ni un estímulo para que las mujeres alteren sus condiciones materiales de vida o se promocionen en diversas actividades. En este artículo nos centramos en la Asignación Universal por Hijo y su incidencia en la vida de las mujeres que la perciben.
Teorías sistémicas de la comunicación
Authors: Baecker Dirk
Published: March 2018

Las teorías sistémicas de la comunicación se derivan de la deconstrucción de la teoría matemática de la comunicación y del modelo de transmisión de Claude Shannon y Warren Weaver. Refiriendo a la pregunta irresuelta sobre la identidad de un mensaje para distintos observadores, estas teorías desarrollaron un modelo selectivo de comunicación. En función de superar el modelo ingenieril de la señalización (en vez de comunicación) propuesto por Shannon y Weaver, las teorías sistémicas no asumen que un mensaje es seleccionado de un set de mensajes posibles, sino que el set de posibles mensajes, así como el mensaje que será seleccionado de ese set (contexto), debe ser construido por los participantes de la comunicación.
La libertad en disputa. Corrientes de la negociación en la teoría social contemporánea
Authors: De Grande Pablo
Published: March 2018

El término ‘negociación’ reconoce una multiplicidad de usos en el campo académico, los cuales incluyen tanto dinámicas abiertas como referencias a procesos de adaptación menos visibles. El presente artículo propone que la noción de negociación se ha desarrollado durante la segunda mitad del siglo XX a partir de dos corrientes disciplinares diferenciables y relativamente autónomas que vieron en ella una vía para expresar el equilibrio entre libertad individual y estructura social. De este modo, la negociación ha servido para señalar los matices que despliega el análisis de la agencia individual puesta en contexto. Este artículo recupera aportes provenientes de la teoría social así como de la economía y de las teorías de juego con el fin de contribuir a una mejor delimitación teórica del concepto de negociación y de la relación entre negociación y agencia.
México y Chile: paradojas democráticas e injusticias distributivas
Authors: Díaz Carlos Alberto
Published: March 2018

Las configuraciones distributivas del Estado, las herencias institucionales dictatoriales y/o autoritarias,la corrupción y la violencia, influyen en las dimensiones culturales de la democracia y la desigualdad en México y Chile. Estos factores han actuado históricamente como dilatadores de la desigualdad mediante redes políticas oscuras, que están presentes de distinta forma en el desarrollo de sus Estados y sus economías. Cuando los rasgos ilegales e informales de estos dilatadores son valorados positivamente, se alteran la solidaridad, la participación en asuntos públicos y la posibilidad de que las contradicciones de la desigualdad se hagan visibles en el espacio público.
Las representaciones de la Confederación Sindical Internacional (CSI) sobre el trabajo decente: un análisis del horizonte utópico sindical en la globalización
Authors: Ghiotto Luciana
Published: March 2018

Este artículo se propone exponer el modo en que la Confederación Sindical Internacional (CSI) se representa la noción de “trabajo decente” lanzada por la Organización Internacional del Trabajo (OIT) en 1999. Para ello se elaboró una codificación a partir del Programa de la CSI de 2006. Se buscó el sentido que la CSI otorga a esta noción, identificando nociones asociadas como “justicia social”, “Estado” y “diálogo social”. Se concluye que la CSI ubica al trabajo decente como el elemento más relevante dentro de su objetivo político, que es la construcción de una “nueva globalización”. Allí se identifica el horizonte utópico que sostiene la Confederación. Se explica que dicho horizonte es expresión de un modo de ser sindical asociado a la subjetividad

determinada por el salario, típico de las formas welfare de la segunda posguerra.
Satisfacción con la democracia en Chile: De lo normativo a lo valorativo
Authors: Cereceda-Marambio Karina , Torres-Solís Amanda
Published: March 2018

En la presente investigación se propone y contrasta empíricamente un modelo teórico para explicar y predecir la satisfacción con la democracia en Chile. Dicho modelo cuenta con siete variables independientes o predictoras, referidas a la percepción de elementos institucionales-formales (i.e., la percepción de la economía personal y familiar, y la confianza en las instituciones), preferencias políticas, valoración presidencial, percepción de la corrupción y aspectos valorativos sobre derechos y libertades. Así, el modelo propuesto considera la influencia de aspectos personales, valorativos y contingentes en la satisfacción con la democracia. Los resultados de esta investigación indican que la satisfacción con la democracia en Chile se sustenta principalmente en el aspecto institucional macro como la confianza en las instituciones y la economía país, por lo que las variables que miden aspectos del orden valórico poseen menos relevancia para la evaluación del

régimen político.
Evaluación docente universitaria: Hacia una perspectiva unificada
Authors: Asún Rodrigo A. , Zúñiga Claudia
Published: March 2018

La calidad de la docencia universitaria se evalúa principalmente a través de cuestionarios aplicados a los estudiantes, los que no siempre surgen de un enfoque teórico sólido. Con el fin de avanzar en la construcción de un modelo teórico que dé sustento a al desarrollo de instrumentos de evaluación, tres fuentes de demandas hacia la docencia universitaria: demandas de los estudiantes, demandas del modelo de formación por competencias y demandas de la tradición de investigación cuantitativa en docencia. A partir del análisis de estas fuentes, se construyó una conceptualización integrada de la calidad de la docencia universitaria que se espera contribuya como herramienta para el desarrollo de mejores instrumentos de evaluación de la calidad de la docencia universitaria.
La figura del ayudante universitario: Concepto, rol y características
Authors: Sánchez-Gómez Victoria , SanMartín Ana N. , Mardones-Segovia Constanza , Fauré Jaime
Published: March 2018

El objetivo de la presente investigación consistió en describir y analizar los significados que estudiantes, ayudantes y profesores asignan a la figura del ayudante universitario. La muestra estuvo compuesta por 43 participantes de una universidad chilena. Éstos respondieron entrevistas semiestructuradas, las cuales fueron analizadas posteriormente mediante Análisis de Contenido. A pesar de que los roles asignados al quehacer del ayudante fueron variados y diversos, es posible comprenderlos y agruparlos en concordancia con la literatura existente en un rol orientador, académico, mediador y social. Las características de un buen ayudante, sin embargo, parecieron ser más amplias que lo propuesto por la literatura, englobando no solo el manejo teórico práctico y ciertas habilidades personales, sino también las habilidades para la enseñanza y un fuerte componente relacional. Finalmente, no se encontraron mayores diferencias en los relatos entre los distintos actores.
La nueva dinámica de la condición social moderna
Authors: Martuccelli Danilo
Published: March 2018

El artículo propone una reconceptualización de la dinámica de la experiencia de la condición social moderna contemporánea. Se procede en tres grandes etapas. En un primer momento se precisan las especificidades de la matriz de la condición moderna y sobre todo la importancia que tuvo en ella el advenimiento de lo social. En segundo lugar, se argumenta que en las sociedades actuales se asiste a una inflexión de la dinámica central de la condición social moderna en torno a la vida en común y las singularidades. En tercer lugar, y luego de evocar ciertas consecuencias normativas de este proceso, se indican algunos de los principales desafíos que esto acarrea en la teoría y el análisis sociológico.
Desconfianza y procedimiento judicial
Authors: Puyol Carolina
Published: March 2018

La desconfianza correspondería a una valoración que todos los seres humanos realizan ante una situación y/o persona, a partir de diferentes características; y que, en el caso de las relaciones humanas, podría generar diversos vicios. Este trabajo presenta una revisión del fenómeno de desconfianza en los procedimientos judiciales por delitos sexuales que afectan a niños, niñas y adolescentes, analizando sus efectos en la sobreabundancia de pruebas. La metodología utilizada correspondió a una de carácter mixto cuantitativa y cualitativa, consistentes en encuestas (N=54) y entrevistas en profundidad (N=6) realizadas jueces y juezas penales, circunscritos a la Región Metropolitana. Los resultados obtenidos muestran deficiencias en diversos hitos del proceso judicial, y sus medios probatorios, al haber escasos insumos de calidad para juzgar y, sobreabundancia de evidencia innecesaria. Finalmente, se observarían características del fenómeno de desconfianza, basadas en deficiencias del proceso, pero también por la naturaleza moral del delito.
Gestión de personas en la Administración Central del Estado y asesoría de la Dirección Nacional del Servicio Civil
Authors: Molina Nicollete
Published: March 2018

El presente estudio analiza la asesoría brindada por la Dirección Nacional del Servicio Civil (DNSC) y estudia como dicha asesoría influye en la consolidación de buenas prácticas laborales en los servicios públicos de la administración central (SPAC). De acuerdo a la indagación efectuada, se ha podido constatar que la DNSC ha logrado constituirse como una agencia especializada en materias para la gestión de las personas en el Estado. Sin embargo, el modelo de asesoría y gestión, presenta aspectos que requieren atención. Entre ellos, los contextos internos de los SPAC que fueron asesorados tuvieron mayor fuerza a la hora de implementar o no, reformas en lo relativo a gestión de personas; La estrategia de gestión de la DNSC, ha respondido a los contextos políticos, generando un apilamiento de iniciativas y reformas en desarrollo de personas; Existen debilidades en la planificación y objetivos de la DNSC, los niveles de logro en la actualidad son parciales y con una evidente disparidad en los niveles de avance de cada SPAC. En suma, se evidenció que el trabajo desarrollado en materias de políticas de desarrollo de personas ha sido parcial, siendo un desafío para la DNSC asumir una labor de rectoría en la materia.
Conflicto etno-ambiental en el marco de la Consulta Indígena
Authors: Peralta Camila
Published: March 2018

Esta investigación tuvo por finalidad generar un debate teórico respecto de las estrategias desarrolladas por las empresas de inversión al momento de plantear proyectos en territorio indígena. Desde una óptica decolonial y de ecología política, indagamos en las percepciones de los actores involucrados en los denominados conflictos etno-ambientales -el Estado, los empresarios y las comunidades indígenas- frente a las estrategias empresariales. Nos enfocamos en la relación entablada entre el Estado chileno y las organizaciones Mapuche, debido a que este pueblo no solo ha logrado posicionarse como un actor relevante al interior de la lucha por la reivindicación de derechos colectivos, sino, de manera particular, en la lucha contra proyectos de inversión que amenazan sus formas de vida, prácticas culturales y territorio. La metodología utilizada fue de carácter cualitativo, lo que permitió conocer y comprender cómo los actores producen, de manera subjetiva e intersubjetiva, su discurso respecto de cuáles y cómo son las estrategias desarrolladas por los empresarios para buscar el consenso con los comuneros mapuche de la zona y también, de qué manera las variables culturales y socioeconómicas afectan las decisiones de los mapuche afectados.
La ciudad de Acapulco
Authors: Peña Rodrigo
Published: March 2018

La ciudad de Acapulco, en el sur de México, construyó fama mundial en la segunda mitad del siglo XX por sus cualidades turísticas. Sin embargo, en los últimos cinco años se ha ubicado como una de las más violentas del país por la alta tasa de homicidios, incremento que se ha relacionado con disputas de grupos criminales, narcotráfico y corrupción de autoridades locales y nacionales. Las víctimas, por supuesto, incluyen ampliamente inocentes, aunque en una proporción difícil de calcular con exactitud. Aunque se han ensayado diferentes explicaciones para explicar la crisis que enfrenta el puerto, este artículo propone hacerlo desde dos perspectivas. Por un lado, utilizando la idea de ciudad para explicar la centralización de procesos de violencia y crimen. Por el otro, a través del análisis la geografía de Acapulco (y más específicamente del puerto y la infraestructura que lo comunica con rutas y destinos en una lógica de mercados criminales) como una variable de explicación. A partir de ambos ese análisis, se argumenta la necesidad de incorporar un enfoque de "rutas y conexiones" en la elaboración de políticas públicas para ciudades con altas condiciones de violencia y criminalidad.
Producción de biogás desde residuos urbanos en Rio de Janeiro
Authors: Ferraço Anaide
Published: March 2018

With the current consensus about the need to decarbonise the energy system to decrease its GHG emissions in order to mitigate global warming, biogas has been growing worldwide as a low carbon energy alternative. Biogas originates from the biological breakdown of organic materials. This process happens in landll sites when organic waste decomposes and produces what is known as landll gas. In compliance with the Brazilian National Policy on Solid Waste, in 2012 Jardim Gramacho landll, was closed, leaving a poll of 1,700 scavengers without their livelihood. De dump was not only important for those workers but also for approximately 12,000 inhabitants depending directly or indirectly from the waste picking activities. After de closure, a biogas plant was built on the site to collect and process methane originated in the old dump. This enterprise presented environmental improvements to the region. However, the residents who worked on the selection of recycling materials were left without a source of income. Up to now not enough public policies were implemented to ensure livelihood improvements to the waste pickers and inhabitants of Jardim Gramacho district.
Anthophyllite Asbestos: The Role of Fiber Width in Mesothelioma Induction Part 2: Further Epidemiological Studies of Occupational, Domestic and Environmental Exposure to Finnish Anthophyllite Asbestos
Authors: Ilgren Edward B. , Hoskins John A.
Published: March 2018

Although people in all sectors of the Finnish anthophyllite industry, including their families, have been heavily exposed to anthophyllite there is no evidence for even a single proven case of attributable mesothelioma. A few cases have been claimed but the evidence either, that they were mesotheliomas or that amphibole exposure was solely to anthophyllite is, in every case examined, insufficient. Even among the population who lived in Karelia in Central Finland who were exposed domestically or enviromentally to anthophyllite released during agricultural and various domestic activities and during transport from the mines, Finnish epidemiology found no risk of mesothelioma. There is also an absence of mesotheliomas reported in the earlier Finnish literature. This anomaly compared to the effects of exposure to other amphiboles is strong support for the role of fiber width in mesothelioma production. Anthophyllite, though, is not without clinical effect. As screening techniques improved it was discovered that of every person over the age of 65 years, one third living in Karelia had bilateral pleural plaques. The area was henceforth called the Endemic Pleural Plaque (EPP) zone. Radiographic analysis of the residents living in the district of Kuusjarvi led to suggestions that the cases resulted from asbestos blown from the Paakila facility via fiber drift as far away as 30 km. Later studies showed that ‘fiber drift’ was very unlikely to be a factor in the radiological findings thus observed.
Intervention Programs for Developing Play Skills in Children With Autistic Spectrum Disorder to Foster Interaction
Authors: Algahtani Faris
Published: March 2018

Autistic spectrum disorder has gained attention in terms of developing therapies and support to enhance the developmental and social attributes of children. The aim of this study is to assess the favourable influence of play therapies among autistic children. An observational analysis has been conducted in a local rehabilitation centre. A class of 250 autistic children, aged between 4 to 5 years, was evaluated. Pre and post analysis for common indications of autism were made with regard to the play therapy. The symptoms, concerning behavioural aspects, were recorded on a simple checklist. The study did not provide any concrete relevancy of being effective for play therapy among the autistic children. The study showed that interventions based on play skills are recognized as imperative approach to develop social associations among children. The developmental approaches of autistic children differ from normal children, as they require different facilities and special attention.
Negative Binomial Regression Model for Road Crash Severity Prediction

In this paper, the Negative Binominal Regression (NBR) technique was used to develop crash severity prediction model in Jordan. The primary crash data needed were obtained from Jordan Traffic Institute for the year 2014. The collected data included number and severity of crashes. The data were organized into eight crash contributing factors including: age, age and gender, drivers’ faults, environmental factors, crash time, roadway defects and vehicle defects. First of all, descriptive analysis of the crash contributing factors was done to identify and quantify factors affecting crash severity, then the NBR technique using R-statistic software was used for the development of the crash prediction model that linked crash severities to the identified factors. The NBR model results indicated that severe crashes decreased significantly as the age of both male and female drivers increased. They significantly decreased as the environmental conditions improved. In addition, sever crashes were significantly higher during weekdays than weekends and in the morning than in the evening. The results also indicated that sever crashes significantly increased as drivers have faults while driving. In addition, mirror and brake deficits were found to be the only factors among all possible vehicle deficits factors that contributed significantly to severe crashes. Finally, it was found that the results of the NBR model are in agreement with the descriptive analysis of the crash contributing factors.

The revolution in information technology and the use of the internet changed the lifestyle of people. A major change was in the way of shopping. Companies started to offer their products online using social network s and people started to buy from the internet. Using social network has many benefits to the users starting from exploring a large variety of products to the very first way of ordering and the availability of the products 24 hours a day. One of the main problems that is found in using a social network is trusting the using social network social network s. the student concern about trusting to buy from the using social network social network s. Trust is a major concern for the merchant too; his concern is how to gain the student trust and to keep it. Many factors play a major role in acquiring the student trust in the online market. These factors rely on the social network characteristics such as design, interactivity and age and other factors vary from the social network quality, service quality, security policy of the social network, the privacy policy, the guarantee offered, the satisfaction of the user, the ease of use, the risk aversion and the culture factors. This study introduces the trusting affecting factors mentioned above and their effect on the trustworthiness factors (ability, benevolence, and integrity) a trust model has been built to show the relation between these factors and the trustworthiness factors.

Background To present the outcomes of the tarsal switch procedure using an anterior approach to correct severe ptosis with poor levator muscle function (<4 mm) with absent or poor Bell’s phenomenon.

Methods This retrospective case series included 11 patients with severe neurogenic or acquired myogenic palpebral ptosis. All patients underwent the tarsal switch procedure through an anterior approach from 2012 to 2015. Margin reflex distance (MRD1 and MRD2) and the palpebral fissure were evaluated preoperatively and postoperatively. Data were compared using the Wilcoxon signed-rank test. P-values <0.05 were considered to indicate statistical significance.

Results Surgery was performed on 18 eyelids (11 patients). The median age at surgery was 57 years (range, 29-86 years). Four patients had unilateral ptosis and seven had bilateral ptosis. Nine patients had myogenic ptosis and two had neurogenic ptosis. Postoperatively, the chin-up position improved in all patients. The MRD1 increased statistically significantly, from 0 mm preoperatively to 1.0 mm postoperatively (P=0.001). The MRD2 decreased statistically significantly, from 4.5 mm preoperatively to 3.0 mm postoperatively (P=0.001). The palpebral fissure did not change (4.0 mm preoperatively to 4.0 mm postoperatively) (P=0.13).

Conclusions The tarsal switch procedure through an anterior approach is an effective alternative for correcting severe ptosis, especially neurogenic or acquired myogenic ptosis. This procedure can be performed with minimal risk of ocular surface exposure and provides stable outcomes.
Volumetric lipoinjection of the fronto-orbital and temporal complex with adipose stem cells for the aesthetic restoration of sequelae of craniosynostosis

Published: March 2018

Background Non-syndromic craniosynostosis causes craniofacial asymmetry and may persist after cranioplasty. These postoperative asymmetries are primarily depressions. In some cases, patients may be subjected to pranks and harassment by their peers, affecting their psychosocial development. We propose lipoinjection enriched with adipose stem cells (ASCs) to treat the sequelae of craniosynostosis in the fronto-orbital and temporal complex in cranioplasty patients, with the goal of improving the appearance of the upper third of the face.

Methods Twelve children (four boys and eight girls) between 4 and 8 years of age (mean age, 6 years) in the postoperative period after treatment for plagiocephaly, brachycephaly, and trigonocephaly were included, with a follow-up period of 1 to 18 months. Fat tissue was obtained from the lower abdomen, and ASCs were isolated using the Yoshimura technique. Lipoinjection was performed using several mini-approaches to ensure adequate distribution.

Results Two different scales were used to evaluate the aesthetic outcomes. At 6 months, three plastic surgeons independent of the study classified the results using a Likert scale. The patients’ parents categorized the results using a visual analog scale at 6, 9, and 18 months. R esults were favorable on both scales, as the patients’ facial appearance improved and they reported increased happiness and self-esteem due to their remodeled facial appearance.

Conclusions We suggest that lipoinjection enriched with ASCs is a good alternative for correcting asymmetry of the fronto-orbital and temporal contour in patients with sequelae of craniosynostosis. This treatment will help boost patients’ self-esteem starting at an early age.
Management based on grading of animation deformity following implant-based subpectoral breast reconstruction

Published: March 2018

Subpectoral breast reconstruction using implants and meshes have been used widely in Europe, the United States and the United Kingdom. Although this technique has several advantages, animation deformity is a well-documented problem. We propose a new grading system to classify breast animation in patients undergoing subpectoral implant based breast reconstruction. We also discuss different techniques to avoid and correct animation deformity.

Academic Libraries on Social Media: Finding the Students and the Information They Want
Authors: Howard Heather A. , Huber Sarah , Carter Lisa V. , Moore Elizabeth Anne
Published: March 2018

Librarians from Purdue University wanted to determine which social media platforms students use, which platforms they would like the library to use, and what content they would like to see from the library on each of these platforms. We conducted a survey at four of the nine campus libraries to determine student social media habits and preferences. Results show that students currently use Facebook, YouTube, and Snapchat more than other social media types; however, students responded that they would like to see the library on Facebook, Instagram, and Twitter. Students wanted nearly all types of content from the libraries on Facebook, Twitter, and Instagram, but they did not want to receive business news or content related to library resources on Snapchat. YouTube was seen as a resource for library service information. We intend to use this information to develop improved communication channels, a clear libraries social media presence, and a cohesive message from all campus libraries.

This issue marks 50 years of Information Technology and Libraries. The scope and ever-accelerating pace of technological change over the five decades since Journal of Library Automation was launched in 1968 mirrors what the world at large has experienced. From “automating” existing services and functions a half century ago, libraries are now using technology to rethink, recreate, and reinvent services — often in areas that simply were in the realm of science fiction.
Classification of affective and social behaviors in public interaction for affective computing and social signal processing
Authors: Konstantinova Maria , Kazimirova Evdokia , Perepelkina Olga
Published: March 2018

There are numerous models for affective states classification and social behavior description. Despite proving their reliability, some of these classifications turn out to be redundant, while others — insufficient for certain practical purposes. In this paper we propose a classification describing human behavior in the course of public interaction. We relied on existing literature to adopt the current achievements to a practical task---to automatically detect various aspects of human behavior. Our goal was not to suggest a new universal model describing human behavior, but to create a quite comprehensive list of affective and social behaviors in public interaction. The final list consists of the following seventeen scales: happiness, surprise, anxiety, anger, sadness, disgust, shame, pride, contempt, admiration, self-presentation, self-disclosure, mental effort, friendliness, engagement, pleasure and self-confidence. These scales concern only behavior patterns which can be observed by outside annotator and do not include personal traits or hidden states.
