Ex-votos fotográficos: la imagen usada como objeto de culto en la región de Alentejo
Authors: Russo Trindade Milene 
Published: April 2018

El siglo XIX ha sido escenario de la introducción de la fotografía en las sociedades y delos constantes cambios que esta ha tenido a nivel tecnológico. De manera gradual, la fotografía se incorporó al cotidiano de todos, pasando la idea de tener y ofrecer fotografías a formar parte del imaginario común. Del mismo modo que las imágenes eran usadas como recuerdo dentro de un álbum de familia, se empezaron a usar también como ofrenda en el campo religioso. En la comunicación propuesta, se expone la investigación doctoral sobre los ex-votos fotográficos en la región de Alentejo, en Portugal. Los ex-votos son ofertas que simbolizan el agradecimiento por una dádiva concedida, siendo común que previamente se haya rezado a un santo o santa pidiendo un voto. No se sabe con exactitud cuando empezó este ritual, pero sabemos que civilizaciones como la romana ya lo practicaban. La oferta votiva es sobretodo conocida a través de formatos como la escultura o la pintura, sin embargo, la fotografía pasó a ser un medio usado a gran escala con el viraje del siglo substituyendo progresivamente a la pintura. Los ex-votos fotográficos se presentan como retratos individuales o de grupo y normalmente se encuentran en las salas anexas de las iglesias. A ellos, suele estar asociado un pequeño texto que describe la persona y el acontecimiento que lleva a la oferta, así como la fecha y el lugar de los hechos. Siendo así, hoy podremos referirnos a estos conjuntos de fotografías, por su dimensión y organización, como colecciones. Su riqueza formal y técnica nos propone una lectura de la historia de los procesos fotográficos, así como también, del modo en elcual ha evolucionado la presentación de fotografías. Por otro lado, observar estas colecciones nos ofrece la oportunidad de conocer a los estudios de fotografía y, sobretodo, de constatar cambios sociales como si estuviésemos ante un archivo.Además, cabe destacar que el uso de fotografías en la práctica votiva constituye una realidad sin límites fronterizos, que nos lleva a colocar en diálogo dos casos particularmente interesantes por su proximidad cultural: el sur de Portugal con el sur de España. Esta relación se muestra de una manera más evidente en las zonas de frontera, como por ejemplo, en el caso del Santuário do Senhor Jesus da Piedade en la localidad portuguesa de Elvas, que alberga ofrendas llevadas hasta allí desde el territorio español.Teniendo en cuenta que la fotografía digital ha cambiado el uso y la relación que teníamos con la imagen, estas colecciones, las cuales representan un recorrido por la historia de la fotografía, por sus cambios formales y técnicos a lo largo de mas de un siglo de existencia, se revelan de una importancia patrimonial e histórica que deberá ser valorizada. La fotografía, en todos sus procesos técnicos, es extremamente delicada y como tal exige que se planteen cuidados para su conservación. En este estudio se pretendeasí, dar visibilidad a los ex-votos fotográficos, como patrimonio a valorizar y, consecuentemente, a conservar.

Abstract. Here we report on measurements made with an improved CO2 Sounder lidar during the ASCENDS 2014 and 2016 airborne campaigns. The changes made to the 2011 version of the lidar included incorporating a rapidly wavelength-tunable, step-locked seed laser in the transmitter, using a much more sensitive HgCdTe APD detector and using an analog digitizer with faster readout time in the receiver. We also improved the lidar's calibration approach and the XCO2 retrieval algorithm. The 2014 and 2016 flights were made over several types of topographic surfaces from 3 to 12 km aircraft altitudes in the continental US. The results are compared to the XCO2 values computed from an airborne in situ sensor during spiral-down maneuvers. The 2014 results show significantly better performance and include measurement of horizontal gradients in XCO2 made over the Midwestern US that agree with chemistry transport models. The results from the 2016 airborne lidar retrievals show precisions of ∼ 0.7 parts per million (ppm) with 1 s averaging over desert surfaces, which is an improvement of about 8 times compared to similar measurements made in 2011. Measurements in 2016 were also made over fresh snow surfaces that have lower surface reflectance at the laser wavelengths. The results from both campaigns showed that the mean values of XCO2 retrieved from the lidar consistently agreed with those based on the in situ sensor to within 1 ppm. The improved precision and accuracy demonstrated in the 2014 and 2016 flights should benefit future airborne science campaigns and advance the technique's readiness for a space-based instrument.

El artículo presenta los resultados de una investigación cuya finalidad es conocer la autopercepción de dominio que tienen los estudiantes de las competencias investigativas en el momento de la realización del Trabajo de Fin de Grado. El estudio se contextualiza en el grado de Pedagogía de la Universidad de Barcelona, y en él participaron 109 estudiantes (60,15% del alumnado matriculado), que contestaron un cuestionario. El enfoque adoptado para las dimensiones del cuestionario fue el de la competencia investigativa como conjunto de competencias específicas del acto de investigar, que siguen la lógica del método científico y su proceso. Los resultados, coincidentes parcialmente con los de otras investigaciones de otros contextos universitarios, muestran niveles medios altos de percepción en general de las competencias investigativas, siendo mayor en escritura y técnicas de recogida y análisis cualitativo y menor en búsquedas bibliográficas especializadas, citación y técnicas cuantitativas, aspectos de especial relevancia en el ámbito académico.
Opinions of Middle School Students on the Justice Concept within the Framework of Social Studies Education
Authors: Oguz Hacat Sibel 
Published: April 2018

The aim of this study is to reveal the opinions of middle school students about the justice concept. The study was carried out in accordance with the document review technique, which is one of the qualitative research methods. The study group consists of 82 students attend in 7th grade receiving education at a middle school in the city of Kastamonu in the school year 2016-2017. Data was obtained using semi-structured interviews consisting of open-ended questions. This data was interpreted using content analysis and by way of coding. Middle school students’ opinions on justice concept are represented in 8 different categories and they use 7 different sayings relating to the justice concept. Whereas the justice concept is most often explained as “Rightfulness”, it is least often conceived as “Abstinence from Committing Crimes”. It is observed that the saying “Justice can do what swords cannot” is used by middle school students most often, and the saying “No merit can be more noble than justice” least often. In light of this information, middle school students can be provided with environments in which they can internalize the justice concept. Furthermore, results about justice can be drawn when its content is broadened. We can do scientific study about justice in more detail by increasing sample group.

Background: Over the past decade, a growing number of older Medicare beneficiaries visit the emergency department (ED) and have been placed in observation care. We investigated and compared the prevalence and factors associated with patients age ≥ 65 years with Medicare insurance who are placed in the hospital, observation care, or discharged following an ED visit.Methods: We conducted a retrospective cohort study using data from a nationally representative 5% sample of Medicare patients age ≥ 65 years during the year 2013. We performed multiple generalized estimating equation (GEE) logistic regression analyses to assess the relationship between placement in a hospital vs. discharge, observation care vs. discharge, and observation care vs. admission.Results: Of 537,455 Medicare beneficiaries age ≥ 65 years who visited an ED in 2013, 48.0% (N = 258,083) were discharged, 10.5% (N = 56,184) placed in observation care, and 41.5% (N = 223,188) were admitted to the inpatient service following the ED visit. The top 2 diagnoses associated with placement in the hospital vs. discharge were ischemic heart disease and renal disease. Patients with symptomatic diagnoses such as chest pain and dizziness were more likely to be placed in observation care following an ED visit as compared to admission to the hospital.Conclusions: Compared to prior studies, we found a greater number of older Medicare ED patients placed in observation care and a lower number admitted to the hospital. Most common diagnoses of placement in observation care were symptom-based as compared to being admitted to the hospital which were disease-based.
An update on the spider genus Hexophthalma (Araneae: Sicariidae) in the Afrotropical region, with descriptions of new species
Authors: Lotz Leon 
Published: April 2018

The described Afrotropical species of the genus Hexophthalma Karsch, 1879 (under the genus name Sicarius Walckenaer, 1847), of the spider family Sicariidae Keyserling, 1880, were recently reviewed. In the present paper the Afrotropical species of the genus Hexophthalma are revisited. After a thorough examination of all the available specimens from nine major collections, the species H. testacea (Purcell, 1908) is here synonymized with H. hahni (Karsch, 1878), three new species are described – H. binfordae sp. nov., H. goanikontesensis sp. nov. (both from Namibia) and H. leroyi sp. nov. (from South Africa) – and the male of H. dolichocephala (Lawrence, 1928) is described for the first time. The distribution of the species is also revised and a new updated key to the species is compiled.

Published: April 2018

Los Teatros debieron resistir frente a múltiples adversidades y no todas relacionadas con el desarrollo de la actividad que amparaban. Los materiales con que se construían y decoraban fueron sus grandes enemigos. Solo como resultado de episodios dramáticos fueron mejorando sus condiciones. Relatamos a continuación las circunstancias que rodearon el incendio que se produjo en el Teatro López de Ayala de Badajoz, vinculado a uno de los episodios más dramáticos de la Guerra Civil española.
BUFONERÍA Y CINETEXTUALIDAD EN LA OBRA DE WOODY ALLEN: LITERATURA Y CINE
Authors: García-Abad Teresa 
Published: April 2018

Además de ser uno de nuestros artistas contemporáneos más fecundos, Woody Allen se ha nutrido de expresiones estéticas diversas –imagen, escritura, música, pintura-- para conformar uno de los estilos más originales y valorados de la creación de nuestro tiempo. El presente ensayo hace un recorrido por una de sus facetas más desconocidas, la de dramaturgo, itinerario que refuerza la relevancia de la escritura en su proceso creativo, así como el humor y la ironía, cualquiera que sea la materia sobre la que actúe. Del papel o la pantalla al escenario, los teatros españoles se han hecho eco de la totalidad de la obra dramática de Woody Allen, pasando por algunos de sus más conocidos diálogos y dramaturgias inspiradas en su cine.

Published: April 2018

Background:Spiral fractures of the tibia are often the result of torsion trauma. In clinical practice, this type of fracture is frequently complicated by posterior malleolus fractures. This study aimed to observe the effectiveness of diagnosis and treatment of these fractures in a single hospital in China. Posterior malleolus fractures are sometimes occult, occurring alongside spiral fractures of the distal third of the tibia; posttraumatic arthritis can result if they are missed.Methods:This study includes 128 consecutive patients with tibia fractures between May 1, 2008, and April 30, 2012. Patients in the early study period underwent radiography only, and subsequent patients underwent both radiography and computed tomography (CT). The causes of the fractures were evaluated. Intramedullar nailing was performed for the tibia fractures. Percutaneous cannulated screw fixation was used for the posterior malleolus fractures. Patients were followed up for a minimum of 3 months.Results:Twenty-eight patients had spiral fractures of the mid-distal third of the tibia. Ten of the 28 patients were complicated by posterior malleolus fractures. Diagnosis was initially missed in one early patient who underwent radiography only. Three cases of posterior malleolus fractures were identified by radiography. A CT was performed in all ten patients and showed that approximately 25% to 50% of the ankle joint surface of posterior malleolus fractures was involved. One early diagnosis was missed that had a displaced posterior malleolus fracture after intramedullary nailing. Using CT as the gold standard, radiography had sensitivity of 33.3%, specificity of 100.0%, positive predictive value of 100%, and negative predictive value of 73.9%. All correctly diagnosed patients healed well, without ankle pain.Conclusions:Computed tomography helped identify most posterior malleolus fractures, and radiography alone might miss it. Intramedullary nailing and posterior malleolus screw fixation were straightforward and effective treatments.

Published: April 2018

Background:Pigmented villonodular synovitis (PVNS) is a rare disorder around the ankle joint. The optimal treatment for diffuse-type PVNS is still controversial because of the high incidence of recurrence. We present the clinical features of our patients and review the current diagnostic and treatment modalities.Methods:Five patients with PVNS located around the ankle were surgically treated. In three patients, diffuse PVNS arose from the ankle joint, and in the other two it arose from the calcaneocuboid and intercuneiform joints. The average follow-up time after surgery was 2.9 years (range, 2–4.6 years).Results:The average time between onset of pain and diagnosis of PVNS was 6.4 years (range, 4–10 years). Arthrotomic tumor resection was performed in all of the patients. In the three patients with ankle joint PVNS, both medial and lateral approaches were used. One patient experienced mild infection at the surgical site, but this healed conservatively. No tumor recurrences had occurred after minimum follow-up of 2 years, although mild pain persisted in the three patients with ankle PVNS.Conclusions:Diagnosis of diffuse PVNS is frequently delayed due to vague symptoms and variable growth patterns. Orthopedic clinicians should be aware of the existence of this lesion, and it should be suspected in patients with persistent ankle swelling. To prevent tumor recurrence, accurate evaluation of tumor location and careful operative planning are mandatory. A combined surgical approach involving medial and lateral incision is necessary to expose the entire joint cavity.

Published: April 2018

Gefitinib, an epidermal growth factor receptor–tyrosine kinase inhibitor (EGFR‐TKI), is an effective treatment for non‐small‐cell lung cancer (NSCLC) with EGFR activating mutations, but inevitably, the clinical efficacy is impeded by the emergence of acquired resistance. The tumor suppressor gene FBXW7 modulates chemosensitivity in various human cancers. However, its role in EGFR‐TKI therapy in NSCLC has not been well studied. Here, we demonstrate that the mice with deficient Fbxw7 have greater susceptibility to urethane‐induced lung tumor development. Through analysis of The Cancer Genome Atlas data, we show that deletion of FBXW7 occurs in 30.9% of lung adenocarcinomas and 63.5% of lung squamous cell carcinomas, which significantly leads to decrease in FBXW7 mRNA expression. The reduction in FBXW7 mRNA level is associated with poor overall survival in lung cancer patients. FBXW7 knockdown dramatically promotes epithelial–mesenchymal transition, migration, and invasion in NSCLC cells. Moreover, with silenced FBXW7, EGFR‐TKI‐sensitive cells become resistant to gefitinib, which is reversed by the mammalian target of rapamycin inhibitor, rapamycin. Furthermore, xenograft mouse model studies show that FBXW7 knockdown enhances tumorigenesis and resistance to gefitinib. Combination of gefitinib with rapamycin treatment suppresses tumor formation of gefitinib‐resistant (GR) FBXW7‐knockdown cells. In conclusion, our findings suggest that loss of FBXW7 promotes NSCLC progression as well as gefitinib resistance and combination of gefitinib and rapamycin may provide an effective therapy for GR NSCLC.
Seismic Moment, Seismic Energy, and Source Duration of Slow Earthquakes: Application of Brownian slow earthquake model to three major subduction zones
Authors: Ide Satoshi , Maury Julie 
Published: April 2018

AbstractTectonic tremors, low‐frequency earthquakes, very low‐frequency earthquakes, and slow slip events are all regarded as components of broadband slow earthquakes, which can be modeled as a stochastic process using Brownian motion. Here we show that the Brownian slow earthquake model provides theoretical relationships among the seismic moment, seismic energy, and source duration of slow earthquakes and that this model explains various estimates of these quantities in three major subduction zones: Japan, Cascadia, and Mexico. While the estimates for these three regions are similar at the seismological frequencies, the seismic moment rates are significantly different in the geodetic observation. This difference is ascribed to the difference in the characteristic times of the Brownian slow earthquake model, which is controlled by the width of the source area. We also show that the model can include non‐Gaussian fluctuations, which better explains recent findings of a near‐constant source duration for low‐frequency earthquake families.
