Intravenous Immunoglobulin in the Treatment of Hematologic Disorders in Pediatrics
Authors: Villanueva Gabriela , de Jong Jill L. O. , McNeer Jennifer L.
Published: January 2017

Intravenous immunoglobulin (IVIG) is pooled immunoglobulin G derived from human blood donors. It was introduced in the early 1980s to treat immunodeficiency disorders. Since then, its use has expanded to other fields such as neurology, rheumatology, and hematology. IVIG has been used to provide passive immunity in qualitative and quantitative immunoglobulin disorders, to neutralize antibodies in immune-mediated diseases, and as an immune modulatory agent. The difficulty of producing IVIG in high quantities, in addition to a growing list of “off-label” indications, has resulted in a worldwide shortage and increase in cost. From a pediatric hematology perspective, IVIG is considered an appropriate therapeutic option in autoimmune cytopenias, sometimes coadministrated with steroids. Its use in other hematologic disorders is questionable, and there is not sufficient evidence to recommend it. This article provides clear information to the general pediatrician about indications for IVIG therapy in children with hematologic disorders.

Published: January 2017

AlMgSi alloys (6XXX series) provide a good strength due to the precipitation of β” and β (Mg2Si) phases. They have also very good formability which is required for different forming process after appropriate heat treatments.This work was carried out to investigate the effect of the addition of copper and the excess of Si on the response of natural and artificial aging of two Al-Mg-Si alloys. The aging parameters on precipitation sequence of two Al-Mg-Si alloys with and without excess Si were studied by DSC, MET and Vickers hardness measurement. The combined effect of Cu, Fe and excess of Si was found to accelerate the precipitation of the hardening phases. The additions of copper to the AlMgSi refine the average of the grain size and have a greater hardening effect compared to the excess silicon addition.
Optimal Homotopy Analysis of Blasius and Sakiadis Newtonian Flows over a Vertical Convective Porous Surface

Published: January 2017

In this article, a comparative analysis of free convective Blasius and Sakiadis flows of a viscous fluid over a vertical porous surface is presented. The relationship between the flow rate and pressure drop as the Newtonian fluid flows past a porous medium is linear; hence Darcy model is adopted. Suitable similarity variables are employed to transform the governing non-linear partial differential equations into a set of coupled non-linear ordinary differential equations. An approximate analytical solution of the coupled ordinary differential equation is obtained using Optimal Homotopy Analysis method (OHAM). The computational results for velocity and temperature profiles are shown graphically for various flow parameters and analyzed. The results show that an increase in convective parameter leads to increase in velocity and temperature profiles. Also, increasing buoyancy parameter increases the velocity profile and decreases the temperature profiles for both Sakiadis and Blasius flow. The temperature distribution at the maximum value of Prandtl in Sakiadis case is greater than the temperature distribution at the maximum value of Prandtl even in Blasius case.

Authors: Silaipillayarputhur Karthik , Al-Saif Ali , Al-Otaibi Musab
Published: January 2017

In this paper, steady state sensible performance analysis on multi pass parallel cross flow exchanger was considered. The inputs to the heat exchanger were described through meaningful physically significant parameters such as number of transfer units, capacity rate ratio and dimensionless input temperature. The inputs to the heat exchager were varied systematically and a parametric study was conducted to determine the thermal performance at each individual pass of the heat exchanger. Heat exchanger’s thermal performance was described through the discharge temperatures that were expressed in a dimensionless form. The results from the study were presented in the form of performance tables. The performance tables employed meaningful and industry recognized dimensionless input parameters and the heat exchanger‘s performance was described through dimensionless discharge temperatures at every pass of the heat exchanger. The developed performance tables shall serve two critical aspects. First, it will help the heat exchanger designers to readily choose an optimum heat exchanger. An undersized heat exchanger shall not deliver the requirements and likewise an oversized heat exchanger shall add unnecessary weight and cost. This aspect was clearly observed in this study as indefinetly increasing the number of transfer units (or surface area) beyond a threshold value didn’t enhance the heat transfer. By employing the performance tables as a guide, the heat exchanger designers can quickly ascertain the performance of the heat exchanger without having to perform simulations and/or lengthy calculations. Second, during operational phase of the heat exchanger, the performance tables can be used to understand the performance variation of the heat exchanger with respect to mass flow rates and/or can help the engineers to choose appropriate mass flow rates for the required heat transfer. The highest heat exchanger performance was observed at the lowest capacity rate ratio and likewise the lowest heat exchanger performance was observed at the highest capacity rate ratio. In-addition, during the operational phase, the performance tables can help to detect an underperforming heat exchanger and can help the engineers to schedule maintenance activity on the heat exchanger equipment.

Authors: Bakhti Amine , Boukhoulda Farouk Benallel
Published: January 2017

The objective of the present work is an analysis of vibratory responses due to the impact of projectile in steel against a glass/polyester composite material under hygrothermal conditions with different energy levels. In the first part of this study, by means of a data acquisition system, a signal processing analysis of the contact force and acceleration of the projectile is carried out in order to deduce the oscillations of the responses. These are generated by the vibrations induced by the contact between the plate and the impactor. The analysis of the vibrations by the calculation of the Fast Fourier Transform (FFT) applied to the oscillations of the contact force allows to defining the resonance frequencies of the plate for the different energy levels. The measure of the Frequency Response Functions (FRF) from the obtained responses allows the determination of the damping of the impacted composite material.In the second part of this study highlights quantitatively and puts into evidence the influence of hygrothermal conditions on the mechanical responses such as contact force, acceleration, frequency and damping of aged and non-aged composite plates.

Authors: Dhavse Rasika , Prashant Kumar , Dabhi Chetan , Darji Anand , Patrikar R.M.
Published: January 2017

This work applies combination of Direct Tunneling model and BSIM4 based ITAT model to explain the leakage of electrons from charged nanocrystals to p-type silicon substrate in data retention condition, for an ultra-thin tunnel oxide, low voltage programmable silicon nanocrystal based flash gate stack. Basic expressions of these models are modified to incorporate the nanocrystals related charge leakage in idle mode. The concept is supported by simulating these models and comparing them with the experimental data. Transition of electrons is considered as a result of Direct Tunneling and their trapping de-trapping via water related hydrogen traps. However, it is found that modified ITAT mechanism is the dominant one. Flat-band voltage shift profile fits accurately with the model with an extrapolated 10 years device lifetime without memory closure. 3 nm thick tunnel oxide and 100 nm sized nanocrystal fabrication with Electron Beam Lithography are main features of the devices.

Published: January 2017

The zirconia fiber reinforced ZrO2 porous composites have been fabricated by precursor infiltration and pyrolysis techniques. The rheological properties and ceramization mechanism of ZrO2 preceramic solution were observed. The results showed that with the increase of infiltration/ pyrolysis cycles the density of as-prepared composites increased. But the compression strength of composite firstly increased and then decreased, which indicates mechanical properties of composites relevant with density, fiber/matrix interface and porous structure. SEM observation revealed fiber pull-out within samples through 17 infiltration/pyrolysis cycles, which would make contributions to the enhanced mechanical properties of composites.

Published: January 2017

В статье рассматриваются вероятности малых уклонений (ВМУ) в равномерной норме для сумм стационарных гауссовских последовательностей. Для постоянных границ и границ, стремящихся к нулю, получены достаточно
общие результаты. Для случая границ, стремящихся к бесконечности, мы изучаем дискретные аналоги дробного броуновского движения (ДБД). Выясняется, что нижние границы для ВМУ переносятся с хорошо изученного случая ДБД на постановку задачи с дискретным временем при обычных предположениях, достаточных для слабой сходимости. В то же время для переноса соответствующих верхних оценок необходима более глубокая информация о спектральной структуре стационарной последовательности.
Cloud vertical distribution from combined surface and space radar/lidar observations at two Arctic atmospheric observations
Authors: Liu Yinghui , Shupe Matthew D. , Wang Zhien , Mace Gerald
Published: January 2017

Abstract. Detailed and accurate vertical distributions of cloud properties (such as cloud fraction, cloud phase, and cloud water content) and their changes are essential to accurately calculate the surface radiative flux and to depict the mean climate state. Surface- and space-based active sensors including radar and lidar are ideal to provide this information due to their superior capability to detect clouds and retrieve cloud microphysical properties. In this study, we compared the annual cycles of cloud property vertical distributions from satellite active sensors and surface-based active sensors at two Arctic atmospheric observation stations, Barrow and Eureka. We used this data to identify the sensors’ respective strengths and limitations and to develop a blended cloud property vertical distribution by combining both sets of observations. Results show that surface-based observations offer a more detailed cloud property vertical distribution from the surface up to 11 km above mean sea level (AMSL) with limitations in the middle and high altitudes; the annual mean total cloud fraction from space-based observations see 25–40 % fewer clouds below 0.5 km than that from surface-based observations, and space-based observations also show much less ice cloud and mixed phase cloud, and slightly greater liquid cloud from the surface to 1 km; space-based observations show comparable cloud fraction between 1 km and 2 km AMSL, and greater cloud fraction above 2 km AMSL than that from surface-based observations. The blended product combines the strength of both products to provide a more reliable annual cycle of cloud property vertical distribution annual cycle from the surface to 11 km AMSL. This information can be valuable for deriving an accurate surface radiative budget in the Arctic and for cloud parameterization evaluation in weather and climate models.

Published: January 2017

Abstract. Tropical forests in NW Amazonia are highly threatened by the expansion of the agricultural frontier and subsequent deforestation. Fire is used, both directly and indirectly, in the Brazilian Amazon to propagate deforestation and increase forest accessibility. Forest fragmentation, a measure of forest degradation, is also attributed to fire occurrence in the tropics. However, outside the Legal Amazonia the role of fire in increasing accessibility and forest fragmentation is less explored. In this study, we compared in five countries sharing this tropical biome in the most North Western part of the Amazon Basin (Venezuela, Colombia, Ecuador, Peru and Brazil). We analysed spatial differences in the timing of peak fire activity and in relation to proximity to roads and rivers using 15 years of MODIS active fire detections. We also distinguished patterns of fire in relation to forest fragmentation by analysing fire distance to the forest edge as a measure of fragmentation for each country. We found significant hemispheric differences in peak fire occurrence with the highest number of fires in the South in 2005 vs. 2007 in the North. we also found difference in peak fire occurrence by country with fire peak in Colombia and Venezuela in February; peak fire in September for Brazil and Peru; and Ecuador presented two fire peaks. We confirmed the relationship between fires and forest fragmentation for all countries; and also found significant differences in the distance of fire to forest edge for each country. These results can inform land use planning at the regional, national and sub-national scale to minimize how road expansion and subsequent access to the amazonian natural resources contribute to fire occurrence, and the associated deforestation and carbon emissions.
Flow angle measurement of a yawed turbine and comparison to
models
Authors: Gallant Tyler , Johnson David A.
Published: January 2017

Abstract. The torque generated by a wind turbine blade is dependent on several parameters, one of which is the angle of attack. Several models for predicting the angle of attack in yawed conditions have been proposed in the literature, but there is a lack of experimental data to use for direct validation. To address this problem, experiments were conducted under controlled conditions at the University of Waterloo Wind Generation Research Facility using a 3.4 m diameter test turbine. A five-hole pressure probe was installed in a modular 3D printed blade and was used to measure the angle of attack, α, as a function of several parameters. Local flow angle measurements for all azimuthal angles were obtained at radial positions of r / R = 0.55 and 0.72 at tip speed ratios (λ) of 5.0, 3.6, and 3.1. The yaw offset of the turbine was varied from −15° to +15°. Span-wise flow angle measurements are presented for the r / R = 0.55 cases, and show the variation in radial flow direction throughout yawed rotation. Experimental results were compared directly to angle of attack values calculated using a model proposed by Morote in 2015. Modeled values were found to be in close agreement with the experimental results. The angle of attack was shown to vary cyclically in the yawed case while remaining mostly constant when aligned with the flow, as expected. These five-hole probe measurements were also used to characterise the upstream flow profile. Wind speeds determined using the five-hole probe measurements are presented and are in agreement with measurements obtained in the wind facility during testing. The quality of results indicates the potential of the developed instrument for wind turbine measurements.

Published: January 2017

Objetivo: Describir el impacto familiar de la sedación paliativa en pacientes con enfermedad avanzada terminal ya fallecidos, desde la percepción del cuidador principal.Método: Estudio cualitativo de enfoque fenomenológico. Se realizaron entrevistas semi-estructuradas a diez cuidadores principales de pacientes con enfermedad terminal fallecidos bajo sedación paliativa, que fueron atendidos por cuidados paliativos en una institución oncológica de Medellín, Colombia entre enero y marzo de 2015. Se analizó la información a partir de categorías preestablecidas: significado, cambios emocionales, cambios estructurales y duelo.Resultado: Los cuidadores no tenían ningún conocimiento previo sobre la sedación. Todos reportan que fueron informados sobre el objetivo y los cambios físicos que podía presentar el paciente; sin embargo, la mitad de ellos refirieron que esta información no fue suficiente para comprender el proceso que enfrentaban. Manifestaron diversos sentimientos (alivio, duda, impotencia, tristeza) antes, durante y después de la sedación. Respecto a los cambios estructurales, la mayoría de las familias se reorganizaron y facilitaron el acompañamiento y cuidado al paciente refiriendo fortalecimiento de las relaciones familiares. Finalmente, se encontró que los cuidadores percibieron que la sedación paliativa facilita el duelo, al aliviar el sufrimiento y permitiendo una buena muerte.Conclusiones: Los cuidadores evalúan la experiencia de sedación como positiva y satisfactoria para aliviar el sufrimiento de su ser querido y el de su familia. Igualmente, facilita el proceso de duelo por la construcción positiva de alivio en torno a la experiencia vivida como familia, fortaleciendo sus relaciones y recordando una buena muerte para su paciente

Published: January 2017

Introduction: Plasmacytoid urothelial carcinoma (PUC) is a highgrade variant of conventional urothelial cell carcinoma. This study is the first to describe the imaging findings of PUC, which are previously unreported, using clinical and histopathological correlation. Methods: With internal review board approval, we identified 22 consecutive patients with PUC from 2007‒2014. Clinical parameters, including age, gender, therapy, surgical margins, and longterm outcome, were recorded. Baseline imaging was reviewed by an abdominal radiologist who evaluated for tumour detectability/ location/morphology, local staging, and presence/location of metastases. Pelvic peritoneal spread of tumour (defined as >5mm thick soft tissue spreading along fascial planes) was also evaluated. Followup imaging was reviewed for presence of local recurrence or metastases.Results: Median age at presentation was 74 years (range 51‒86), with only three female patients. Imaging features of the primary tumour in this study were not unique for PUC. Muscle-invasive disease was present on pathology in 19/22 (86%) of tumours, with distant metastases in 2/22 (9%) at baseline imaging. Pelvic peritoneal spread of tumour was radiologically present in 4/20 (20%) at baseline. During followup, recurrent/residual tumour was documented in 16/22 (73%) patients and 7/16 (44%) patients eventually developed distant metastases. Median time to disease recurrence in patients who underwent curative surgery was three months (range 0‒19).Conclusions: PUC is an aggressive variant of urothelial carcinoma with poor prognosis. Pelvic peritoneal spread of tumour as thick sheets extending along fascial planes may represent a characteristic imaging finding of locally advanced PUC.

La fibrose rétropéritonéale (FRP) est une maladie rare, caractérisée par la présence d’un tissu fibro-inflammatoire aberrant qui se forme souvent autour de la portion sous-rénale de l’aorte abdominale et des artères iliaques. Une obstruction urétérale est souvent observée. Récemment, la FPR idiopathique est rapportée parmi les manifestations de la maladie à IgG4. L’imagerie joue un rôle important dans le diagnostic de la FRP. Les glucocorticoïdes sont le traitement de référence, utilisés en monothérapie ou en association avec d’autres agents médicamenteux. En cas d’échec des mesures conservatrices, la chirurgie peut être proposée. Récemment, des techniques minimalement invasives ont été utilisées.
Combining Ability and Heterosis of Selected Grain and Forage Dual Purpose Sorghum Genotypes
Authors: Chikuta Sally , Odong Thomas , Kabi Fred , Rubaihayo Patrick
Published: January 2017

Sorghum is an important food and feed source in mixed crop-livestock production systems where its dual usage is a preferred option, especially among the resource poor small-scale farmers. Attempts to improve fodder quality traits in maize have been at the expense of grain traits and vice versa, but other studies demonstrated that it was possible to select for high stem biomass without compromising the improvement of grain yields in sorghum. As a follow up to this effort, this study was undertaken to estimate the combining ability of grain and forage sorghum genotypes and determine heterosis for several traits as a criteria for improving dual purpose sorghum cultivars. Four grain and four forage sorghum cultivars were crossed to generate 23 crosses following the half diallel mating design scheme at Makerere University Agricultural Research institute Kabanyolo (MUARIK) in 2013. The crosses were evaluated at three locations in Uganda during two rainy seasons of 2014. Data were taken and analysed on leaf area, leaf-stem ratio, plant height, seed weight, grain yield, and biomass. Results indicated that the gene action for the traits under observation was controlled by both additive and non additive genetic effects. Majority of the parental lines had significant GCA estimates for all traits except line 20 for grain yield, lines 22 and 34 for plant height, line 35 for leaf-stem ratio, and line 22 for days to flowering. Significant (P ≤ 0.05) SCA estimates were prominent in most of the individual parental combinations for all traits except leaf area and leaf-stem ratio indicating the role of dominance gene action. Bakers ratio and heritability coefficients were > 52% for biomass, flowering duration and plant height indicating that genetic gains can be achieved by conventional breeding for the three traits. Heterosis in grain yield and biomass over both the mid and better parents was shown by more than half of the crosses studied. This study suggested that both inter and intra allelic interactions were involved in the expression of the traits.

Published: January 2017

Antioxidant and phytochemical compounds of fruits can vary widely depending on many factors such as processing and maturity stage as one of the major contributors. Therefore, this study investigated the antioxidant activity and phytochemical attributes of fresh and freeze-dried Lepisanthes fruticosa fruit extracts at eight different maturity stages. The freeze-dried extracts were obtained by lyophilisation using a freeze-dryer. In general, antioxidant activity and phytochemical contents of both fresh (FLF) and freeze-dried (FDLF) extracts showed a decrease with fruit maturation. Among the eight maturity stages developed for L. fruticosa, the lower maturity (unripe) stages exhibited the strongest potential, with stage 1 being the most notable. The FDLF fruit extracts were found to be significantly (P < 0.05) stronger radical scavenger than FLF extracts at all maturity stages tested. The IC50 values of FDLF for the eight maturity stages were more effective, with stage 1 showing the lowest IC50 (1.57 mg/ml). Total phenolic content of FDLF was also significantly (P < 0.05) higher than FLF at all eight stages tested, with the highest also being shown at stage 1 (15848.96 ± 401.82 mg/100 g). On the contrary, FLF extracts displayed significantly (P < 0.05) higher total flavonoid content than FDLF at almost all stages except for 2, 3 and 6. The highest content was shown in stage 1 with 37.35 ± 0.77 mg/100 g. These findings showed that antioxidant activity and phytochemical content of L. fruticosa fruits were significantly affected by processing and maturity. The obtained results are important for the promotion of use of L. fruticosa fruit extracts as a natural antioxidant in functional food production in the future.

Published: January 2017

Toxicity of chlorantraniliprole was assayed against young (first and second instars) and older larvae (third and fourth instars) of cabbage Pieris rapae (Lepidoptera: Pieridae) on cabbage (Brassicae oleracea), and persistence of field–aged leaf residue of chlorantraniliprole was assayed with 5-old-day larvae of P. rapae on cabbage. Efficacies of chlorantraniliprole and other newer insecticides to P. rapae were tested under field conditions for two seasons in Hubei province in China. The LC50 value of chlorantraniliprole for early and later P. rapae larvae were 7.92 and 11.34 mg/L by contact toxicity, respectively. The LC50 value of chlorantraniliprole for early and later P. rapae larvae were 0.95 and 4.32 mg/L through ingestion, respectively. The toxicity of field-aged leaf residues of chlorantraniliprole (0-, 3-, 5-, 7-, 10-, 14-, 21-, 25-, and 28-day-old residues) declined gradually under the field conditions. Almost all larvae died on day 5 after feeding on the leaves with 0-21-day residue, and the mortalities were as high as 83.3% and 72.5% for the 21- and 25-day-old leaf residues. Chlorantraniliprole application suppressed P. rapae larvae below the economic threshold for 21-28 days. The field efficacy trials show that chlorantraniliprole at 52 mg a.i /L rate was effective against P. rapae larvae on cabbage, providing marketable cabbage with three applications per season. In addition, chlorantraniliprole was as effective as indoxacarb and spinosad and significantly more effective than emamectin benzoate.
Ethnic Cognition and Affect of British-Born Chinese Children
Authors: Lam Virginia L. , Tran Diane H.
Published: January 2017

Little research has explored the ethnic cognition and affect of ethnic Chinese children from Britain and Europe, contrasting the established literature from North America. The present paper reports research which tested these developmental aspects among British-born ethnic Chinese children aged 5 to 10 years from London attending a Chinese supplementary language school. Children were given measures on categorisation skills, self- and other identifications, target matching (by gender and ethnicity), own preference and rejection, inferred preference and rejection of mothers, and trait attributions. Results showed that age was associated with categorisation skills and target matching, but not self- or other ethnic identifications on which children exhibited high performance. The majority of children preferred Chinese peers and rejected non-Chinese peers and inferred their mothers to do the same, and own and inferred mothers’ rejection choices were related to each other. These findings are discussed in relation to previous research findings from other ethnic minority children including British Chinese children and ethnic Chinese children from elsewhere, and the theoretical and contextual factors that may impact British Chinese children’s ethnic identity and attitudes.

En este trabajo se expresa una vinculación entre cuerpo y moda. Para ello, mediante una mirada interna propia, se comprende cómo un individuo puede realizar un autoanálisis de su cuerpo. Además, elaborando una mirada externa ajena se busca acceder a las concepciones que otros tienen sobre nosotros. Por último, se presta atención al espacio del “centro comercial” donde ambas miradas convergen. Para concluir, se hace una llamada a la importancia de re-pensar el cuerpo, con el objetivo de llegar a ser más conscientes de la necesidad de obtener armas de pensamientos útiles para encontrar el bienestar propio y ajeno.  
Encorsetar la diferencia: la discapacidad como “valor”
Authors: Moscoso Perez Melania
Published: January 2017

La irrupción de la discapacidad como objeto de estudio de las ciencias sociales y las humanidades ha desplazado el significado originariamente clínico de esta noción, centrado en la limitación funcional, hacia acepciones de matiz más claramente político, que la conciben, como ha señalado la canadiense Kelly Fritsch, como un locus privilegiado de opresión social. El texto analiza cómo  el concepto de discapacidad utilizado por el modelo social se presta a usos retóricos que la convierten en la única categoría de vulnerabilidad legítima, con la consecuencia indeseable de generar una nueva distinción social entre aquellos que pueden sancionar su vulnerabilidad mediante categorías médicas y aquellos cuyas limitaciones reciben una calificación moral.
Cuerpos vulnerables y vidas precarias. ¿Un retorno de lo humano en la filosofía política de Judith Butler?
Authors: Ingala Gómez Emma
Published: January 2017

El presente texto (1) interroga el relativamente reciente retorno del concepto de lo humano a la filosofía política de Judith Butler –esto es, se pregunta por las razones de este retorno, por la condición de este retorno y por la concepción de lo humano que retorna– y (2) examina en qué medida este retorno transforma, matiza o modula la comprensión butleriana del cuerpo y de la vida. A partir de estos dos puntos, se tratará de arrojar luz sobre el llamado “giro ético” de Butler –que no supone en absoluto un abandono de la política, como algunos lectores han interpretado– y sobre la preeminencia que nociones como las de precariedad y vulnerabilidad han cobrado en sus teorías.

El presente trabajo plantea un diálogo entre la ontología de la actualidad en clave biopolítica defendida por Roberto Esposito y la historia conceptual como filosofía política de Giuseppe Duso. Además de presentar en sus líneas básicas ambas propuestas, el objetivo es mostrar, más allá de las diferencias, las convergencias en su deconstrucción de los conceptos políticos modernos, por un lado, y en las tareas que asignan a la filosofía política, por el otro.

En efecto, toda su obra y su vida tratan de la escucha de esta vivencia humana que consiste en la unidad relacional del cuerpo y algo más, que es el alma. Así sus lecturas órficas y de la mística, en su sentido religioso, le permiten atender una y otra vez a esta entrañada relación humana y decantarse, al mismo tiempo, por el ejercicio de la libertad como dominio de lo menos hacia lo más.
La filosofía que ríe: La Anatomía de la melancolía de Robert Burton y la metacrítica de la Ilustración
Authors: Canterla González Cinta
Published: January 2017

Hamann utilizó para su metacrítica de la Ilustración la figura de Demócrito como filósofo que ríe, recogiéndola de la misma tradición en la que Burton se situaba. La melancolía de la razón le servirá para realizar una crítica de la mala filosofía por su abandono del cuerpo.
El cuerpo en los estudios sobre cine: gestus femenino, o tecnologías y teratologías del género y de la (pos)memoria
Authors: Ciancio Belén
Published: January 2017

“Donnez-moi donc un corps!”, el grito filosófico con el que comienza el capítulo 8 de L’Image-temps de Gilles Deleuze, configuraría una serie de modulaciones acerca del cine moderno, del cuerpo, del cerebro y de la memoria, así como del devenir. La conjetura de este trabajo es que, a través del concepto de “tecnologías del género”, surgido desde el feminismo en los mismos años en que Deleuze publica  sus libros sobre cine, se abriría una segunda línea donde el cuerpo no sólo es un concepto para la teoría, sino imagen-materia experimental en la teoría y práctica fílmica feminista así como en la teoría queer. Entre ambas líneas estaría el concepto de “tecnologías de la memoria” (y de la posmemoria).

 
El buen gusto como el tacto de nuestra razón (Los usos y estilos en la concepción del cuerpo y la moda) Good taste and feel of our reason (The uses and styles in the design of the body and fashion)
Authors: Lara Nieto María del Carmen , Lara Lara Fernando
Published: January 2017

La “moda” es un concepto frecuentado por Jovellanos explícita e implícitamente cuando se ocupa de otros conceptos como opinión, gusto, carácter liviano, capricho, frivolidad, ingenio, lujo. El Diccionario de la Real Academia lo define del siguiente modo: “Uso, modo o costumbre que está en boga durante algún tiempo, o en determinado país, con especialidad en los trajes, telas y adornos, principalmente los recién introducidos”. No obstante podemos aplicarlo, y de hecho lo aplicamos habitualmente, a otros ámbitos y contextos.
Cuerpo, arte y escuela. El lugar del desnudo femenino en los libros de texto de ciencias sociales
Authors: Pérez Guerrero Vicente Miguel
Published: January 2017

En este trabajo nos preguntamos por cómo la enseñanza escolar del “desnudo femenino”, en el área de conocimiento de la ESO (Educación Obligatoria Secundaria), pudiera influir en la idea que los alumnos se forjan del cuerpo, de sí mismo y el de los otros. Tanto si tenemos presente que la identidad de género es siempre una identidad corporal, como que la identidad del desnudo en el Arte se asocia a la mujer, procede interrogarse por cómo se trata el desnudo femenino en los libros de texto. 
La tecnología de biomejora: ¿hasta dónde debemos garantizar las oportunidades de bienestar?
Authors: Campos Serena Olga
Published: January 2017

Las biotecnologías en desarrollo tienen fuertes implicaciones más allá de los aspectos centrados en la satisfacción de ciertas necesidades individuales. Hay implicadas nuevas categorías moralmente relevantes, y tienen que ver con nuestra comprensión de la justicia distributiva, igualdad de oportunidades, nuestras obligaciones y derechos como padres, y nuestras obligaciones morales hacia los animales no humanos. Esta última cuestión es considerada particularmente determinante si demostramos que ellos son sujetos  de derechos morales. Cuando intentamos determinar las prescripciones prácticas de este esquema argumentativo nos encontraremos con la obligación de analizar si las técnicas de mejora podrían ser consideradas como una herramienta para proporcionar más igualdad, dadas las situaciones naturales individuales de partida tan diferentes

El trabajo finaliza planteando algunas críticas a la epistemología que subyace a la concepción del cuerpo transhumanista.
Carne barroca: voluptuosidad, sumisión, sublimación
Authors: Martínez Martínez Francisco José
Published: January 2017

Este trabajo presenta tres aspectos del cuerpo en el Barroco: el cuerpo religioso  sufriente y triunfante, el cuerpo político sometido y supliciado y el cuerpo amoroso acariciado y adorado. Se trata de mostrar la ambigüedad radical del Barroco que oscila entre el apego a la vida y el culto de la muerte acabando en una tristeza resignada que sin embargo no puede dejar de mostrar cierta nostalgia respecto al sueño renacentista de afirmación de la vida, la libertad y el amor
La fuerza política de la teoría del valor-escisión de Roswitha Scholz
Authors: Martínez Domínguez Irene
Published: January 2017

En esta ponencia se intenta resumir la teoría crítica del valor-escisión elaborada por Roswitha Scholz, que pretende presentar a capitalismo y patriarcado como sistemas inseparables. El valor-escisión delimitaría la esfera de lo productivo y lo público, e invisibiliza su necesaria relación con las actividades no revalorizan capital pero son necesarias para la la vida. Estas esferas corresponderían a lo masculino y lo femenino como atribuciones de género asignadas. Se intenta aplicar su teoría, principalmente centrada en lo económico, al ámbito político con ayuda de las tesis principales de Pierre Bourdieu.
Dostoievski: una lección de anatomía desde el subsuelo
Authors: Rivera León Lorena
Published: January 2017

El artículo está centrado en los Apuntes del subsuelo de F. M. Dostoievski. Se aborda la presencia del cuerpo en esta novela breve que marca el punto de inflexión hacia lo que muchos estudiosos han considerado una filosofía trágica en la obra del escritor ruso. La Lección de anatomía del Dr. Joan Deijman, pintada por Rembrandt en 1656, brinda el contrapunto para dilucidar cuál es la concepción de la naturaleza humana que Dostoievski delinea en esta obra.
Reinventando a Artigas: Entonces ¿mi nombre suena todavía en mi país?.
Authors: Gracia Arce Beatriz
Published: January 2017

La figura de Artigas ha tenido un tratamiento muy diferente a lo largo del tiempo. Denostado duramente en las décadas inmediatas a la independencia y tachado por sus detractores contemporáneos de anarquista y enemigo del orden y de la propiedad, fue reivindicado como héroe nacional cuando Uruguay, hacia finales del s. XIX consolida su independencia, convirtiéndose en símbolo de la Unidad en oportunidad en que los partidos blanco y colorado que estaban enfrentados en guerras civiles. En el s. XX, coincidiendo con la consolidación de la democracia política, son puestos de relieve sobre todo los aspectos de la «Patria Vieja», pero será cuando las posturas marxistas entren en la escena cuando se reformule la imagen de Artigas. Este artículo ofrece una nueva lectura para entender su figura.

The figure of Artigas has had a very different treatment over time. Harshly reviled in the immediate decades to independence and branded by his contemporary detractors as an anarchist and an enemy of order and property, he was vindicated as a national hero when Uruguay, towards the end of the s. XIX consolidates its independence, becoming a symbol of Unity at the time that the white and red parties that were faced in civil wars. In the S. XX, coinciding with the consolidation of political democracy, the aspects of the "Old Homeland" are highlighted above all, but it will be when Marxist positions enter the scene that Artigas' image is reformulated. This article offers a new reading to understand your figure.
