Campos figurativos en ¡Oh hada cibernética!de Carlos Germán Belli

Nosotros buscamos definir el poemario a partir de la siguiente hipótesis: El viaje es el medio por el cual se configura la identidad de la voz poética en ¡Oh Hada Cibernética!, relacionada esta con la frustración, el desencanto y la alienación. Consideramos que, en el poemario, esta visión es planteada a partir de la idea del viajero, como ser que construye una identidad a partir de su relación con el mundo. Además que las etapas características del viaje, como son la partida, el tránsito y la llegada, se encuentran presentes en el texto. Tomamos la idea de las etapas del viaje del trabajo presentado por Ángel Gasquet en el libro Diez estudios sobre literaturas de viajes (2006). Nuestra metodología de interpretación parte de los conceptos sobre la Retórica General Textual de Stefano Arduini (2000), este investigador plantea que las figuras son el medio por el cual podemos ordenar y conocer el mundo, a causa de la relación de estas con el lenguaje, siendo este la manera por la cual lo construimos. Desarrollamos nuestro trabajo a partir de tres capítulos. En el primero presentamos los conceptos operatorios sobre la Retórica General Textual. Abordamos lo referente a campo retórico y campos figurativos. De manera general, Arduini (2000) define el primero como la vasta área referencial que usa el sujeto para producir su texto y el segundo a través del concepto de las figuras como medios para ordenar y conocer el mundo. También, exponemos, de manera breve, algunas generalidades en torno a la idea del viaje. No buscamos debatir sobre este tipo de literatura, ni definirla como género o subgénero, solo mencionamos elementos centrales relacionados a este concepto; presentando aquello que se entiende por viaje, las implicancias de este y cómo construye el viajero su identidad a partir del movimiento. Señalamos las tres etapas presentes: partida, tránsito y llegada. Estos nos permitirán ordenar nuestro análisis. Nuestro segundo capítulo lo desarrollamos en tres partes, usando como base lo referente al campo retórico. En estas, presentamos lo relacionado al contexto de la producción de la poesía de Carlos Germán Belli, limitándolo a su primera etapa, la cual está relacionada a lo social y, de manera particular, en la situación del sujeto en el mundo. Presente en esta etapa se encuentra, también, la conjugación entre un lenguaje moderno y uno antiguo de Siglo de oro. El contexto de estas producciones está relacionado con el de la Generación del 50, como ya se ha mencionado en las primeras líneas. En el segundo subcapítulo centraremos nuestro interés en torno a la crítica y la recepción de la poesía de Belli y sobre qué perspectivas la han definido los estudios literarios. Concluiremos el capítulo exponiendo las periodizaciones definidas sobre la producción de nuestro autor, y con ello, determinar bajo qué límites se encuentra el ¡Oh, Hada Cibernética! A partir de los campos figurativos, en el último capítulo interpretaremos el poemario, buscando demostrar que la idea del viaje funciona como medio por el cual la voz poética define una identidad de frustración, desencanto y alienación. Analizaremos cuatro poemas, divididos estos por las etapas del viaje: partida, tránsito y llegada. Para finalizar, debemos mencionar que usamos la primera edición del poemario impresa en el año 1961. La decisión de trabajar esta edición y no otras posteriores del texto, parte de nuestro deseo de buscar centrarnos en lo primigenio, conocer la edición príncipe nos ayudará en futuros trabajos a determinar qué razones pudieron llevar al autor para presentar nuevas ediciones del ¡Oh Hada Cibernética!, con cambios en la cantidad de poemas y los versos.Tesi

Su salud a la mano (your health at hand): patient perceptions about a bilingual patient portal in the Los Angeles safety net.

ObjectivesDriven by beneficial patient-centered outcomes associated with patient portal use and the Affordable Care Act, portal implementation has expanded into safety nets-health systems that offer access to care to a large share of uninsured, Medicaid, and other vulnerable populations. However, little attention has been paid to the factors that affect portal accessibility by the vulnerable patients served by these health systems-including those who are limited English proficient (LEP).Materials and methodsThe Los Angeles County Department of Health Services (LAC DHS), the second-largest safety net system in the nation, launched its first patient portal, and one of the few bilingual English-Spanish interfaces in existence, in March of 2015. To explore portal awareness and perceptions, we conducted focus groups with LAC DHS patients, in English and Spanish (LEP). The Technology Acceptance Model was used to guide thematic analysis of focus group data.ResultsOf the 46 participants, 37 were patients and 9 were caretakers; 23 were English-speaking and 23 Spanish-speaking LEP. All patients had diabetes or hypertension. Over half had an annual household income <$10 000, yet 78% of English-speaking and 65% of Spanish-speaking LEP participants reported at-home Internet access. Participants' discussion centered around 3 major thematic narratives: (1) participants' awareness or attitudes about the LAC DHS portal; (2) role of culture, language, or community with regard to portal accessibility and utility; and (3) perceived needs for successful portal implementation.ConclusionsSafety net participants identified concrete benefits to the portal and emphasized the need for portal engagement that offered accessible education, support, and resources in clinical and community settings. The portal offers an additional opportunity to engage the patient and family with trusted and validated health information, and should be further developed in this capacity. This study provides a better understanding of preferred improvements of patient portal engagement that guide broader health technology efforts to address electronic health disparities

Adherence to Competing Strategies for Colorectal Cancer Screening Over 3 Years

We have shown that, in a randomized trial comparing adherence to different colorectal cancer (CRC) screening strategies, participants assigned to either fecal occult blood testing (FOBT) or given a choice between FOBT and colonoscopy had significantly higher adherence than those assigned to colonoscopy during the first year. However, how adherence to screening changes over time is unknown

Graphene nanoplatelets enhanced myo-inositol for solar thermal energy storage

Thermal behavior of nanocomposite phase change materials, Myo-inostol (MI) (a sugar alcohol) added with graphene nanoplatelets (GNN) as a solar thermal energy storage system, for use in the temperature range of 100–260 °C was studied. GNN is added to MI with mass fraction of 1.0, 2.0 and 3.0 wt%. Thermal and chemical stability of MI and MI-GNN were investigated before and after 50 thermal cycles. Results showed that the dispersion of GNN into pure MI was effective, no crystal change and chemical reaction had taken place between GNN and MI before and after thermal cycling, only physical interaction between them had taken place. GNN particles were dispersed throughout the MI with small aggregates. The heat of fusion was found to decrease by 14.13%, 15.06% and 17.63% and heat of solidification by 13.02%, 23.12% and 29.68% for MI-GNN with 1.0, 2.0 and 3.0 wt% of GNN added to MI respectively.Authors would like to acknowledge the funding obtained for the UKIERI-DST Thematic partnership (IND/CONT/E/14-15/381) DST/INT/UK/P-105/2014) and in-kind support of an industrial partner, Bharat Heavy Electrical Ltd., which made this research possible

Low mass fraction impregnation with graphene oxide (GO) enhances thermo-physical properties of paraffin for heat storage applications

Whereas previous researchers analyzed the thermal behavior of paraffin waxes impregnated with graphene oxide nanoparticles (P-GONP) at high mass fraction ( > 1%), this paper analyzes behavior and stability at only 0.3% mass fraction. GONP was prepared by Hummer’s method. The morphology was studied using scanning electron microscope (SEM), transmission electron microscope (TEM), X-Ray diffraction (XRD) and Fourier Transformation-Infrared (FT-IR) Spectrometer and the thermal properties were measured using laser flash analyser (LFA), differential scanning calorimetry (DSC), thermo-gravimetric analysis (TGA) and thermal cycling. LFA showed a 101.2% and 94.5% increase in the thermal conductivity of P-GONP compared to pure paraffin (P) in solid and liquid state respectively. Melting and solidifying temperatures and latent heat were found to be 63.5, 59 °C & 102 kJ/kg and 57.5, 56 °C & 64.7 kJ/kg for P and P-GONP respectively. Thermal cycling over 4000 cycles showed that P-GONP was 27% more stable than P. The latent heat was 64.7 kJ/kg, a 36.5% deterioration compared to virgin paraffin. Compared against higher mass fraction impregnation, lower mass fraction P-GONP was found to have almost equivalent thermo-physical properties (namely thermal conductivity, melting and solidifying characteristics, thermo-chemical stability and reliability) while providing considerable cost saving

Phase change materials as smart nanomaterials for thermal energy storage in buildings

Nowadays, energy production and consumption in buildings play an important role in the economic development of countries. For instance, buildings are central to the EU?s energy efficiency policy, as nearly 40% of final energy consumption and 36% of greenhouse gas emissions are attributable to houses, offices, shops, and other buildings. For achievement of highly energy-efficient buildings, significant paradigm shifts are necessary, particularly in the production requirements for cost-effective, durable, energy-efficient building envelopes. The application of phase change materials (PCMs) for thermal energy storage (TES) in building envelopes can assist the reduction of energy demands associated to the heating/cooling necessary to ensure adequate inner thermal comfort. PCMs are defined as a group of materials that can store/release relevant quantities of thermal energy upon a change in their physical phase (latent heat). In many applications, such storage of energy leads to energy conservation within the system (i.e. the building), thus resulting in improved energy efficiency. Heat is absorbed or released when the material changes from solid to liquid and vice versa. Therefore, PCMs readily and predictably change their phase with a certain input of energy and release this energy at a later time. PCMs must have a suitable phase change temperature range and the latent heat of fusion for the building environment. The optimal phase change temperature depends on the comfort temperature. Also, a PCM must have an adequate conductivity rate to be able to react fast to indoor temperature variations. However, the phase change temperature ranges of the typical PCMs used in buildings are limited, and their thermal conductivity is low. To further improve the efficiency of the energy saving with PCM, the possibility of using more than one type of PCM with distinct melting ranges and specific enthalpies (termed as hybrid PCM) is reported here. Furthermore, a numerical study is conducted to investigate the mixture of nanoparticles and PCM as alternative way to enhance the thermal properties of PCM. On the basis of knowledge acquired here, concept of nanoparticle with PCM system can be employed to scopes of energy-efficient residential and commercial buildings.(undefined)info:eu-repo/semantics/publishedVersio
