De cómo una revista propone un modelo de cultura a un pueblo
Authors: Valderrama Valderrama Jairo 
Published: March 2021

Es ya un lugar común, dentro de los estudios sobre cultura, afirmar que los medios masivos de comunicación tienen un impacto sobre la forma de conducirse y de pensar de los pueblos. Sin embargo, las investigaciones que pretenden mostrar cómo se da esa relación medio-cultura en casos concretos son escasas, por lo menos en América Latina. Esta ponencia busca dar cuenta de algunos de los resultados de la investigación que se adelanta en el marco del Doctorado en Ciencias de la Comunicación de la Universidad Austral y cuyo objetivo central es dilucidar el modelo de cultura que propone un medio de comunicación colombiano de amplia difusión durante las tres últimas décadas del siglo XX.El medio de comunicación es la revista Magazín Dominical (MD), del diario El Espectador (EE), de Bogotá, elegido por su diversidad temática, la forma de usar los contenidos y su amplio impacto en la sociedad colombiana en un contexto político-social muy particular. Para su estudio, a partir del método de análisis de contenido, se establecieron varias categorías culturales que permitieron establecer el modelo de cultura implícito en la revista, sus características temáticas, la frecuencia y la orientación liberal. Esas categorías son: el pensamiento crítico y el debate, la participación abierta a sectores populares, el cuestionamiento institucional, la inquietud social, la visión de mundo, el papel del hombre en el mundo y la revisión histórica. Por su puesto, su selección no es fruto del azar, sino de la revisión textual y de las apreciaciones del equipo editorial que conformó la revista durante un periodo coyuntural de Colombia. Sus miembros publicaron luego, en 1997, un compendio en tres volúmenes, fruto de un trabajo detallado de selección, que demuestra la universalidad y vigencia de los contenidos.Esta ponencia cuenta con tres momentos básicos. Inicialmente, se expondrá el marco general de la investigación: la relevancia del Magazín Dominical y el método de Análisis de Contenido. En un segundo momento, se explicará cómo se aplicó el método a las categorías culturales diseñadas y cómo se cristaliza un modelo de cultura en el Magazín Dominical. Finalmente, se mostrará cómo este procedimiento es aplicable a otras investigaciones similares y redunda en beneficio de una comprensión más detallada de la relación inextricable entre medios masivos de comunicación y cultura; una comprensión que tal vez permita apreciar desde otra óptica que el mundo humano no es más que una urdimbre infinita de símbolos. Como lo asegurara Foucault de Don Quijote:Don Quijote ha tomado su realidad. Realidad que sólo debe al lenguaje y que permanece por completo en el interior de las palabras. La verdad de Don Quijote no está en la relación de las palabras con el mundo, sino en esta tenue y constante relación que las marcas verbales tejen entre ellas mismas

Authors: Saidi Busyra Buyung 
Published: March 2021

Assessment adaptation of several new superior rice varieties on new rice fields affected by seawater intrusion was carried out in Tungkal Ilir Subdistrict, West Tanjung Jabung District, from April to October 2018. The study applied randomized block designs (RBD) with four replications. The treatments consisted of four new rice high yielding varities suitable for tidal/swamps areas namely Inpara 3, Inpara 8, Inpara 9, and Inpari 34 Salin Agritan, and one local rice variety (Londo) as control. Three stems seedlings per clump were planted at the age of 21-25 days, using a 4:1 Legowo planting system. Fertilizer application consisted of basic fertilizer (1.0 Mg ha-1 of lime, 2.5 Mg ha-1 of manure, and 75 kg ha-1 of urea) and supplementary fertilizer (SP-36 150 kg ha-1 and KCl 125 kg ha-1),. Urea supplementation is given based on observations with a leaf color chart (LCC). The results of the study showed that the four new rice HYVs were more adapted as compared to the local rice variety. The performance of the tested new rice HYVs showed quite a good growth appearance and productivity. The highest production was obtained in Inpari 34 Salin Agritan variety 2.85 Mg ha-1, while Inpara 3, Inpara 8, and Inpara 9 ranged between 2.0 and 2.1 Mg ha-1, while the local variety’s productivity was 1.9 Mg ha-1.

Published: March 2021

AbstractEfficient oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) processes highly rely on the rational design and synthesis of high‐performance electrocatalysts. Herein, comprehensive characterizations and density functional theory (DFT) calculations are combined to verify the important roles of the crystallinity and oxygen vacancy levels of Co(II) oxide (CoO) on ORR and OER activities. A facile and controllable vacuum‐calcination strategy is utilized to convert Co(OH)2 into oxygen‐defective amorphous‐crystalline CoO (namely ODAC‐CoO) nanosheets. With the carefully controlled crystallinity and oxygen vacancy levels, the optimal ODAC‐CoO sample exhibits dramatically enhanced ORR and OER electrocatalytic activities compared with the pure crystalline CoO counterpart. The assembled liquid and quasi‐solid‐state Zn–air batteries with ODAC‐CoO as cathode material achieve remarkable specific capacity, power density, and excellent cycling stability, outperforming the benchmark Pt/C+IrO2 catalysts. This study theoretically proposes and experimentally demonstrates that the simultaneous introduction of amorphous structures and oxygen vacancies could be an effective avenue towards high‐performance electrocatalytic ORR and OER.

Published: March 2021

AbstractStraining the vanadium dimers along the rutile c‐axis can be used to tune the metal‐to‐insulator transition (MIT) of VO2 but has thus far been limited to TiO2 substrates. In this work VO2/MgF2 epitaxial films are grown via molecular beam epitaxy (MBE) to strain engineer the transition temperature (TMIT). First, growth parameters are optimized by varying the synthesis temperature of the MgF2 (001) substrate (TS) using a combination of X‐ray diffraction techniques, temperature dependent transport, and soft X‐ray photoelectron spectroscopy. It is determined that TS values greater than 350 °C induce Mg and F interdiffusion and ultimately the relaxation of the VO2 layer. Using the optimized growth temperature, VO2/MgF2 (101) and (110) films are then synthesized. The three film orientations display MITs with transition temperatures in the range of 15–60 °C through precise strain engineering.

Published: March 2021

AbstractGut microbiota have close interactions with the host. It can affect cancer progression and the outcomes of cancer therapy, including chemotherapy, immunotherapy, and radiotherapy. Therefore, approaches toward the modulation of gut microbiota will enhance cancer prevention and treatment. Modern drug delivery systems (DDS) are emerging as rational and promising tools for microbiota intervention. These delivery systems have compensated for the obstacles associated with traditional treatments. In this review, the essential roles of gut microbiota in carcinogenesis, cancer progression, and various cancer therapies are first introduced. Next, advances in DDS that are aimed at enhancing the efficacy of cancer therapy by modulating or engineering gut microbiota are highlighted. Finally, the challenges and opportunities associated with the application of DDS targeting gut microbiota for cancer prevention and treatment are briefly discussed.
Bio Based Batteries

Published: March 2021

AbstractThe expanding use of electrical power generated from wind turbines and solar photovoltaic plants is enabled by the decreasing cost of electrical energy from sun and wind. With the advent of electrical energy from the intermittent solar and wind energy resources comes the requirement that electricity must be stored for use over time. The huge demand for materials for such storage systems will require a considerable energy input in extraction, processing and materials formulation, and new and sustainable electrochemical systems need to be developed. Storing electrical energy in bio based batteries is one of the options for handling the rapid expansion of renewable and variable electrical energy generated in wind turbines and in solar photovoltaic systems, from small to large. With projected needs for storage at 300 GWh for the coming decade, there are many niches for new technologies and possibilities. A supply line of materials for energy storage materials could be ultimately based on photosynthesis, in the form of materials derived from plants. Redox activity is possible in lignin, humic acid, and polyphenolic macromolecules, sometimes by electrochemical activation of redox groups.
Sample size and power considerations for cluster randomized trials with count outcomes subject to right truncation
Authors: Li Fan , Tong Guangyu 
Published: March 2021

AbstractCluster randomized trials (CRTs) are widely used in epidemiological and public health studies assessing population‐level effect of group‐based interventions. One important application of CRTs is the control of vector‐borne disease, such as malaria. However, a particular challenge for designing these trials is that the primary outcome involves counts of episodes that are subject to right truncation. While sample size formulas have been developed for CRTs with clustered counts, they are not directly applicable when the counts are right truncated. To address this limitation, we discuss two marginal modeling approaches for the analysis of CRTs with truncated counts and develop two corresponding closed‐form sample size formulas to facilitate the design of such trials. The proposed sample size formulas allow investigators to explore the power under a large number of scenarios without computationally intensive simulations. The proposed formulas are validated in extensive simulations. We further explore the implication of right truncation on power and apply the proposed formulas to illustrate the power calculation for a malaria control CRT where the primary outcome is subject to right truncation.

Published: March 2021

AbstractBackgroundCerebral small vessel disease (SVD) leads to reduced quality of life (QOL), but the mechanisms underlying this relationship remain unknown. This study investigated multivariate relationships between radiological markers of SVD and domain‐specific QOL deficits, as well as potential mediators, in patients with SVD.MethodsClinical and neuroimaging measures were obtained from a pooled sample of 174 SVD patients from the St. George's Cognition and Neuroimaging in Stroke and PRESsure in established cERebral small VEssel disease studies. Lacunes, white matter hyperintensities, and microbleeds were defined as radiological markers of SVD and delineated using MRI. QOL was assessed using the Stroke‐Specific Quality of Life Scale. Multivariate linear regression was used to determine whether SVD markers were associated with domain‐specific QOL deficits. Significant associations were further investigated using mediation analysis to examine whether functional disability or cognition was potential mediators.ResultsMultivariate regression analyses revealed that lacunes were associated with total QOL score (β = −8.22, p = .02), as well as reductions in mobility (β = −1.41, p = .008) and language‐related subdomains (β = −0.69, p = .033). White matter hyperintensities and microbleeds showed univariate correlations with QOL, but these became nonsignificant during multivariate analyses. Mediation analyses revealed that functional disability, defined as reduced activities of daily living, and executive function, partially mediated the relationship between lacunes and total QOL, as well as mobility‐related QOL, but not language‐related QOL.ConclusionsLacunar infarcts have the most detrimental effect on QOL in SVD patients, particularly in the mobility and language‐related subdomains. These effects may be partially explained by a reduction in activities of daily living. These results may inform targeted interventions to improve QOL in patients with SVD.

AbstractObjectiveThe present study compared 10‐year clinical outcomes between transradial access (TRA) and transfemoral access (TFA) for left main (LM) percutaneous coronary intervention (PCI).BackgroundThere are limited data regarding the long‐term safety and efficacy of TRA for LM PCI.MethodsThis retrospective study evaluated consecutive patients who underwent unprotected LM PCI between January 2004 and December 2008 at Fu Wai Hospital. The exclusion criteria were age of less than 18 years and presentation with acute myocardial infarction. The primary endpoint was major adverse cardiac or cerebrovascular events (MACCE), which was defined as a composite of all‐cause death, myocardial infarction, stroke, and any revascularization at the 10‐year follow‐up.ResultsAmong 913 eligible patients, TRA was used for 417 patients (45.7%) and TFA was used for 496 patients (54.3%). The 30‐day clinical outcomes were similar between the two groups. Results from the 10‐year follow‐up revealed that MACCE occurred in 180 patients (46.7%) from the TRA group and in 239 patients (51.2%) from the TFA group (log‐rank p = .3). The TRA and TFA groups also had low and comparable cumulative rates of all‐cause death (14.6% vs. 17.3%, log‐rank p = .56) and cardiac death (7.9% vs. 9.1%, log‐rank p = .7).ConclusionThe present study revealed no significant differences in long‐term clinical outcomes when TRA or TFA were used for LM PCI.

Published: March 2021

AbstractIschemic complications after percutaneous decannulation of veno‐arterial extracorporeal membrane oxygenation (va‐ECMO) are not rare and can lead to significant morbidity or even mortality in case of delayed diagnosis or treatment. A possible cause of thromboembolic complications is the formation of thrombus between in the short segment between the large bore retrograde arterial cannula of va‐ECMO and the antegrade limb perfusion sheath due to absence of blood flow (dead space). In this case report, we demonstrate a new technique of flushing the dead space to prevent embolic complications during va‐ECMO decannulation.
