Authors: Arcos Pumarola Jordi 
Published: May 2017

Resumen: El presente artículo tiene como objetivo considerar las oportunidades para la didáctica de la filosofía que se nos ofrecen desde la educación patrimonial. Para ello, se valorará la viabilidad de desarrollar propuestas educativas relacionadas con la filosofía a través del discurso expositivo, tradicionalmente utilizado por disciplinas como el arte o la historia en museos y centros de interpretación, pero infrautilizado por la filosofía. Así, a partir de la noción de museografía didáctica se reflexionará sobre la presentación de la filosofía en el contexto museográfico para bosquejar cómo innovar satisfactoriamente en su didáctica a través del medio expositivo.Palabras clave: didáctica de la filosofía, educación patrimonial, museografía didáctica. English title: Exploring the possibilities of the didactics of philosophy in the field of heritage educationAbstract: This paper considers the opportunities that the field of heritage education opens to teaching philosophy. I explore the viability of developing educative proposals for teaching philosophy through the exhibition discourse, traditionally used by disciplines such as the arts or history in museums or interpretation centres, but underused in philosophy. The concept of didactic museography will be the basis for reflecting on the presentation of philosophical content in a museographic context with the aim of outlining how to innovate satisfactorily in its didactics through the exhibition media. Keywords: didactics of philosophy, didactic museography, heritage education.

La educación en Ciberciudadanía Responsable
Authors: Rodríguez Gordo Carlos 
Published: May 2017

Resumen: Ante el fortalecimiento del papel de la tecnología en la sociedad actual, se hace necesario pensar el rol de aquella desde un punto de vista más radical, examinando el fenómeno mismo y sus consecuencias. La Filosofía tiene un papel fundamental a la hora de examinar y proponer alternativas educativas que contemplen las particularidades del proceso formativo del individuo y su papel como ciudadano en una sociedad profundamente mediada por la tecnología. Partiendo de las afirmaciones de algunos autores como Chomsky, Benkler, Prensky, Ortega y Gasset, Habermas y, especialmente, Hans Jonas, propongo el concepto de “Ciberciudananía Responsable” como marco crítico del Homo Tecnologicus, centrado en el pensar más que en el hacer y que pivota sobre tres temas fundamentales: alfabetización digital, fomento de la participación en red y uso de tecnologías libres. Palabras clave: tecnología, educación, ciberciudadanía, ética, responsabilidad. English title: Education for Responsible CybercitizenshipAbstract: Given the strengthening of the role of technology in today’s society, it is necessary to think about the role of technology from a more radical point of view, examining the phenomenon itself and its consequences. Philosophy has a fundamental role in examining and proposing educational alternatives that contemplate the particularities of the individual’s formative process and his role as a citizen in a society deeply mediated by technology. Relying on the views of authors such as Chomsky, Benkler, Prensky, Ortega y Gasset, Habermas and especially Hans Jonas, I propose the concept of “Responsible Cybercitizenship” as a critical framework of Homo Technologicus, which focuses on thinking rather than doing and hinges on three fundamental themes: digital literacy, promotion of online participation, and use of open source technologies. Keywords: technology, education, cybercitizenship, ethics, responsibility.
Investigation of the causes of the longitudinal variation of the electron density in the Weddell Sea Anomaly

Published: May 2017

AbstractThis paper investigates and quantifies the causes of the Weddell Sea Anomaly (WSA), a region near the tip of South America extending from approximately 30° to 120°W geographic longitude and 50° to 75°S geographic latitude at solar minimum between 2007 and 2010. This region is unusual because the midnight peak electron density exceeds the midday peak electron density in summer. This study is far more quantitative than previous studies because, unlike other models, it assimilates selected data parameters to constrain a physical model in order to investigate other aspects of the data. It is shown that the commonly accepted explanation that the WSA is related to the magnetic field declination and inclination effects on the neutral wind does not explain the longitudinal variation of the electron density. Rather, longitudinal changes in the neutral winds and neutral densities are the most likely explanation for the WSA. These longitudinal wind and density changes are attributed to the varying latitudinal distance from the auroral zone energy input. No contributions from the plasmasphere or other sources are required. Furthermore, it is shown that a widely used empirical thermosphere density model overestimates the longitudinal changes in the WSA region.
Orographic rainfall hot spots in the Andes‐Amazon transition according to the TRMM precipitation radar and in situ data
Authors: Chavez Steven P. , Takahashi Ken 
Published: May 2017

AbstractThe Andes‐Amazon transition, along the eastern Peruvian Andes, features “hot spots” with strong precipitation. Using 15 years of Tropical Rainfall Measuring Mission PR data we established a robust relation between terrain elevation and mean surface precipitation, with the latter peaking around 1000 m above sea level (asl), coinciding with the moisture flux peak of the South American Low Level Jet (SALLJ). There is strong diurnal variability, with afternoon (13–18 LT) convection in the Amazon plains, while on the eastern slopes (1000–2000 m asl), after the forcing associated with the thermal heating of the Andes subsides, convection grows during the night and surface precipitation peaks around 01–06 LT and organizes into mesoscale convective systems (MCSs). These then displace downslope to an terrain elevation of 700 m asl with stratiform regions spreading upslope and downslope and then decay during the remainder of the morning. The large MCSs contribute with at least 50% of daily rainfall (60% of the 01–06 LT rainfall). On synoptic scales, the large MCSs are more common in stronger SALLJ conditions, although subtropical cold surges are responsible for 16% of the cases.
Trajectories of thermospheric air parcels flowing over Alaska, reconstructed from ground‐based wind measurements
Authors: Dhadly Manbharat , Conde Mark 
Published: May 2017

AbstractIt is widely presumed that the convective stability and enormous kinematic viscosity of Earth's upper thermosphere hinders development of both horizontal and vertical wind shears and other gradients. Any strong local structure (over scale sizes of several hundreds of kilometers) that might somehow form would be expected to dissipate rapidly. Air flow in such an atmosphere should be relatively simple, and transport effects only slowly disperse and mix air masses. However, our observations show that wind fields in Earth's thermosphere have much more local‐scale structure than usually predicated by current modeling techniques, at least at auroral latitudes; they complicate air parcel trajectories enormously, relative to typical expectations. For tracing air parcels, we used wind measurements of an all‐sky Scanning Doppler Fabry‐Perot interferometer and reconstructed time‐resolved two‐dimensional maps of the horizontal vector wind field to infer forward and backward air parcel trajectories over time. This is the first comprehensive study to visualize the complex motions of thermospheric air parcels carried through the actual observed local‐scale structures in the high‐latitude winds. Results show that thermospheric air parcel transport is a very difficult observational problem, because the trajectories followed are very sensitive to the detailed features of the driving wind field. To reconstruct the actual motion of a given air parcel requires wind measurements everywhere along the trajectory followed, with spatial resolutions of 100 km or less, and temporal resolutions of a few minutes or better. Understanding such transport is important, for example, in predicting the global‐scale impacts of aurorally generated composition perturbations.

AbstractOcean fields that initialize coupled TC prediction models must accurately represent the dynamics of mesoscale features and the associated distribution of upper ocean temperature and salinity. They must also provide unbiased realizations of upper ocean heat content and stratification. Ocean Observing System Simulation Experiments (OSSEs) are performed for three storms: Isaac, 2012; Edouard, 2014; and Gonzalo, 2014. These OSSEs assess the impact of rapid‐response prestorm ocean profile surveys on improving ocean model initialization. Two types of surveys are evaluated: airborne deployments of expendable profilers and deployments of in situ thermistor chains along lines intersecting predicted storm paths. Assimilation of the existing ocean observing system substantially constrains mesoscale structure in dynamical fields, primarily because of the four available altimeters. However, these observations only modestly constrain mesoscale structure and bias in upper ocean thermal fields. Adding rapid‐response airborne surveys to these observing systems produces substantial additional correction in thermal fields, but minimal additional correction in dynamical fields. Without altimetry assimilation, rapid‐response profiles produce large additional correction in both dynamical and thermal fields. Airborne CTDs sampling temperature and salinity over 1000 m versus XBTs sampling temperature over 400 m produce additional correction for dynamical fields, but not for upper ocean thermal fields. Airborne surveys are generally more effective than thermistor chain deployments because they can sample a larger area at higher horizontal resolution and because the latter only measures temperature over the upper ∼100 m. Both airborne profile surveys and thermistor chain deployments effectively reduce upper ocean thermal biases.
Phytoplankton bloom triggered by an anticyclonic eddy: The combined effect of eddy‐Ekman pumping and winter mixing

Published: May 2017

AbstractRecent composite based researches reveal that anticyclonic eddies facilitate the growth of phytoplankton in the subtropical gyres. Two dynamical mechanisms, eddy‐Ekman pumping and winter mixing, have been examined individually, but their relative and combined effects remain unclear. Using satellite observations and model simulations, this study investigated the process of a distinct phytoplankton bloom generated in an anticyclonic eddy in the nutrient‐depleted southeastern Indian Ocean. The bloom propagated westward along with the eddy for more than 600 km from late April to August in 2010. The peak of surface chlorophyll concentration in the eddy is 2.2 times larger than the mean value of the ambient. The development of the bloom is dominated by the winter deepening of mixed layer, whose velocity in vertical nutrient flux is on average 3 times larger than that of eddy‐Ekman pumping. The results of a 1‐D physical‐biogeochemical model demonstrate that the role of eddy‐Ekman pumping is also indispensable, because it not only transports extra nutrients into the mixed layer, but also results in significant chlorophyll enrichment in subsurface water. The superposition of eddy‐Ekman pumping on winter mixing triples the chlorophyll both at the surface and in the upper layer, and the entrainment of subsurface phytoplankton into the mixed layer contributes significantly to the surface bloom, especially in its initial stage. Both the satellite observations and model simulation show that eddy‐Ekman pumping can lead to an early occurrence of the bloom for more than 2 weeks.
Tropical cloud and precipitation regimes as seen from near‐simultaneous TRMM, CloudSat, and CALIPSO observations and comparison with ISCCP
Authors: Luo Zhengzhao Johnny , Anderson Ricardo C. , Rossow William B. , Takahashi Hanii 
Published: May 2017

AbstractAlthough Tropical Rainfall Measuring Mission (TRMM) and CloudSat/CALIPSO fly in different orbits, they frequently cross each other so that for the period between 2006 and 2010, a total of 15,986 intersect lines occurred within 20 min of each other from 30°S to 30°N, providing a rare opportunity to study tropical cloud and precipitation regimes and their internal vertical structure from near‐simultaneous measurements by these active sensors. A k‐means cluster analysis of TRMM and CloudSat matchups identifies three tropical cloud and precipitation regimes: the first two regimes correspond to, respectively, organized deep convection with heavy rain and cirrus anvils with moderate rain; the third regime is a convectively suppressed regime that can be further divided into three subregimes, which correspond to, respectively, stratocumulus clouds with drizzle, cirrus overlying low clouds, and nonprecipitating cumulus. Inclusion of CALIPSO data adds to the dynamic range of cloud properties and identifies one more cluster; subcluster analysis further identifies a thin, midlevel cloud regime associated with tropical mountain ranges. The radar‐lidar cloud regimes are compared with the International Satellite Cloud Climatology Project (ISCCP) weather states (WSs) for the extended tropics. Focus is placed on the four convectively active WSs, namely, WS1–WS4. ISCCP WS1 and WS2 are found to be counterparts of Regime 1 and Regime 2 in radar‐lidar observations, respectively. ISCCP WS3 and WS4, which are mainly isolated convection and broken, detached cirrus, do not have a strong association with any individual radar and lidar regimes, a likely effect of the different sampling strategies between ISCCP and active sensors and patchy cloudiness of these WSs.

AbstractLand‐atmosphere interactions are important to climate prediction, but the underlying effects of surface forcing of the atmosphere are not well understood. In the U.S. Southern Great Plains, grassland/pasture and winter wheat are the dominant land covers but have distinct growing periods that may differently influence land‐atmosphere coupling during spring and summer. Variables that influence surface flux partitioning can change seasonally, depending on the state of local vegetation. Here we use surface observations from multiple sites in the U.S. Department of Energy Atmospheric Radiation Measurement Southern Great Plains Climate Research Facility and statistical modeling at a paired grassland/agricultural site within this facility to quantify land cover influence on surface energy balance and variables controlling evaporative fraction (latent heat flux normalized by the sum of sensible and latent heat fluxes). We demonstrate that the radiative balance and evaporative fraction are closely related to green leaf area at both winter wheat and grassland/pasture sites and that the early summer harvest of winter wheat abruptly shifts the relationship between evaporative fraction and surface state variables. Prior to harvest, evaporative fraction of winter wheat is strongly influenced by leaf area and soil‐atmosphere temperature differences. After harvest, variations in soil moisture have a stronger effect on evaporative fraction. This is in contrast with grassland/pasture sites, where variation in green leaf area has a large influence on evaporative fraction throughout spring and summer, and changes in soil‐atmosphere temperature difference and soil moisture are of relatively minor importance.
What causes seasonal variation of migrating diurnal tide observed by the Mars Climate Sounder?
Authors: Wu Zhaopeng , Li Tao , Dou Xiankang 
Published: May 2017

AbstractWe use two Martian years' temperature data from Mars Climate Sounder (MCS) cross‐track observations to extract the migrating diurnal tide (MDT) and investigate its spatial and seasonal variation from the perspective of classical tidal theory by Hough mode decomposition. The results suggest that during the equinox the vertically propagating (1, 1) mode is dominant at all altitudes from the near surface to ~0.1 Pa with the magnitude growing with height. The trapped modes (1, −2), (1, −4), and (1, −6) are restricted to the lower altitudes with a similar vertical structure. Both the (1, 1) and (1, −2) modes have clearly semiannual variations. The comparison between Hough modes components of MDT and dust and water ice heating rate indicates that both the dust and water ice contribute to tidal excitation. However, both the annual and semiannual variations of dust heating rate are out of phase with those in MDT, while semiannual variation of the water ice heating rate is in phase, indicating that the water ice may contribute to the semiannual variation of MDT. Using model wind results, we also find that the zonal mean zonal wind and its latitudinal shear at the low latitudes modify the vertical propagation condition of the MDT (1, 1) mode and further affect its seasonal variation. The semiannual variations of equatorial MDT and its corresponding mechanism on Mars are comparable to those on Earth, suggesting that the two planets may have more common characteristics.
Fault diagnosis and condition monitoring of wind turbines

Published: May 2017

SummaryThis paper describes a model‐free method for the fault diagnosis and condition monitoring of rotor systems in wind turbines. Both fault diagnosis and monitoring can be achieved without using a model for the wind turbine, applied controller, or wind profiles. The method is based on measurements from standard sensors on modern wind turbines, including moment sensors and rotor angle sensors. This approach will allow the method to be applied to existing wind turbines without any modifications.The method is based on the detection of asymmetries in the rotor system caused by changes or faults in the rotor system. A multiblade coordinate transformation is used directly on the measured flap‐wise and edge‐wise moments followed by signal modulation. Changes or faults in the rotor system will result in unique signatures in the set of modulation signals. These signatures are described through the amplitudes and phase information of the modulation signals. It is possible to detect and isolate which blade is faulty or has been changed based on these signatures. Furthermore, the faulty component can be isolated, ie, the actuator, sensor or blade, and the type of fault can be determined. The method can be used both on‐ and off‐line.

AbstractEarly mortality (EM; death ≤ 6 months from diagnosis) has been reported in several newly diagnosed multiple myeloma (NDMM) trials. Before the era of novel agents, the incidence was 10%‐14%. Causes of death included infections/pneumonia, renal failure, refractory disease, and cardiac events. Staging systems, such as the revised International Staging System (r‐ISS), and prognostic factors including cytogenetics, lactate dehydrogenase levels, and myeloma‐specific factors, are useful to assess overall prognosis; however, they cannot predict EM. We evaluated patients treated with novel agents in the Connect MM® Registry and identified risk factors of the EM cohort. Eligible patients were enrolled in the registry within 60 days of diagnosis. Univariate and multivariate analyses were conducted to evaluate associations between baseline characteristics and EM. Prediction matrices for EM were constructed from a logistic model. Between September 2009 and December 2011, 1493 patients were enrolled in the registry and had adequate follow‐up. Of these patients, 102 (6.8%) had EM and 1391 (93.2%) survived for > 180 days. Baseline factors significantly associated with increased EM risk included age > 75 years, higher Eastern Cooperative Oncology Group performance status, lower EQ‐5D mobility score, higher ISS stage, lower platelet count, and prior hypertension. Renal insufficiency trended toward increased EM risk. These risk factors were incorporated into a prediction matrix for EM. The EM prediction matrix uses differential weighting of risk factors to calculate EM risk in patients with NDMM. Identifying patients at risk for EM may provide new opportunities to implement patient‐specific treatment strategies to improve outcomes.
Ultrasound evaluation of adult‐acquired flatfoot deformity: Emphasis on the involvement of spring ligament
Authors: Sirlyn Quanson 
Published: May 2017

AbstractAdult‐acquired flatfoot deformity (AAFD), a condition commonly caused by tibialis posterior tendon (TPT) dysfunction, has recently been recognised to encompass a spectrum of other deformities, including the disruption of the spring ligament complex. This case series reviews eight examples of chronic AAFD, outlines the sonographic assessment of the TPT and spring ligament and depicts various abnormalities of the TPT and spring ligament that are relevant to AAFD. The importance to always include the spring ligament during the assessment of AAFD will be addressed, as misdiagnosis of the involvement of the spring ligament could lead to inappropriate operative management.
