The Narrative Tactics of Chaucer's Monk
Authors: Irvin Matthew W. 
Published: January 2021

ABSTRACT
Recent criticism on Chaucer's Monk often reads the Monk through discourses of subjectivity. Working from Michel de Certeau's theory of the tactic, this article argues that the Monk should best be understood not as a subject but as a rhetorical representation of the monastic estate, and that his tale should be read as an affective (and effective) rhetorical weapon against that estate's enemies, the noble Knight and the civic-elite Host who is also the governor of the game. By deploying tragedies, which take the noble estate as their subject, the Monk shows how the monastic estate's forms of possession, especially collection, position it to be better able than the nobility to maintain its grasp on wealth in the face of chance. The monastic habit of patience becomes an effective tactic for dealing with the pain of fortune.

Authors: Pavez María Mercedes , Barrera Juana , Coloma Carmen Julia 
Published: January 2021

Los estudiantes de enseñanza media suelen evidenciar problemas en el manejo del discurso oral y escrito, lo que incide en su competencia comunicativa.
Generalmente se estudia el discurso escrito, en particular la comprensión lectora. Sin embargo, la comprensión de discursos orales también es importante en la actividad académica. Por ello, se investiga si existe relación entre el rendimiento escolar y la comprensión de discursos orales en 120 estudiantes (60 de 1 medio y
60 de 3 medio), seleccionados aleatoriamente. Se evalúa la comprensión de breves discursos narrativos, descriptivos y argumentativos, presentados oralmente y en
forma individual. Se efectuó un análisis de correlación entre la comprensión de discursos y los promedios de notas. Según los resultados, la comprensión de discursos orales se correlaciona con el rendimiento escolar y esta relación se advierte especialmente en los alumnos de primero medio. Se destaca también la correlación con algunas asignaturas en particular como Castellano y Ciencias Sociales.
Hacia una evaluación de los aprendizajes en una perspectiva constructivista
Authors: Ahumada Acevedo Pedro 
Published: January 2021

El presente artículo constituye un serio intento de analizar la evaluación del aprendizaje desde una perspectiva constructivista. Se plantean aquellos aspectos o funciones de la evaluación que deberían permanecer y aquellos que necesitan ser asumidos de una forma diferente por parte de los profesores. El artículo procura centrarse en la realidad nacional, haciendo hincapié en consideraciones que aluden a los cambios epistemológicos y metodológicos que la Reforma Educacional recientemente ha puesto en marcha.
El marco en que se ha centrado el análisis plantea una directa relación con el intento de lograr en los estudiantes aprendizajes con sentido y que les resulten altamente significativos.
El autor expresa que un enfoque constructivista reconsidera el concepto de contenidos, haciendo suya una nueva tipología de los mismos. La propuesta de distintos tipos de instrumentos evaluativos para los diferentes tipos de contenidos
resulta importante considerar en una concepción globalizadora del proceso enseñanza-aprendizaje.
Establecimientos Educacionales en Conflictos: Grupos de Resistencia en su Interior
Authors: Llaña Mena Mónica , Escudero Burrows Ethel 
Published: January 2021

Esta investigación se orientó, en una primera etapa, a recoger antecedentes acerca de la situación de oposición y resistencia escolar que estaría obstaculizando la
implementación de los cambios propuestos a través de la Reforma Educacional en marcha. En una segunda fase se diseñó y aplicó un modelo de intervención para enfrentar multidisciplinariamente el conflicto escolar.
Se focalizó en un establecimiento educacional polivalente en el cual se presentaban conductas de resistencia. Se trataba de conocer como se expresaba la oposición a la escuela, los estilos, modos de resistencia y las formas de disciplinamiento en su interior, para así reconstruir los significados o articulaciones de sentido que elaboraban alumnos y profesores con el fin de explicar su situación en ella y contar a la vez con información confiable que permitiera diseñar un modelo experimental de intervención para proponer en una segunda etapa y su aplicación en contextos de resistencia.
Metodológicamente el estudio se planteó desde la perspectiva de la Sociología Comprensiva, ya que el objetivo era, a través de la observación reiterada de las
prácticas escolares, de entrevistas y de grupos de discusión - identificar las construcciones de sentido que los profesores y alumnos elaboran en este contexto.
La formación de educadores de la infancia y la innovación pedagógica
Authors: Díaz Castillo Alondra 
Published: January 2021

Con la puesta en marcha de la Carrera de Educación Parvularia y Escolares Iniciales, la Universidad de Chile asume nuevamente el rol que le cabe en a promoción de la educación pública, abre un espacio al debate sobre sus problemáticas y a la construcción interdisciplinaria de conocimiento sobre la formación docente inicial y en servicio. .
Para apoyar los procesos propios de la instalación de las innovaciones que propone la nueva carrera, se encuentra en desarrollo el proyecto "La Formación de Educadores de la Infancia y la Innovación Pedagógica", auspiciado por la Agencia Interamericana para la Cooperación y el Desarrollo IACD de la Organización de Estados Americanos OEA. Su objetivo central es aplicar y probar un programa de formación pedagógica inicial de educadores de infancia temprana, mediante la conformación y acción coordinada de un equipo de especialistas, con incorporación de actores claves para su desarrollo: docentes formadores, de aula, estudiantes de pedagogía y especialistas de reconocida trayectoria y producción en las áreas que cubre el proyecto.
Andares curriculares en América Latina
Authors: Díaz-Barriga Ángel 
Published: January 2021

El campo del curriculum se ha conformado en una disciplina compleja en el ámbito de las ciencias sociales. De alguna forma es una disciplina contemporánea, ya que surge en el proceso de consolidación de los sistemas educativos nacionales y, en las transformaciones sociales y científicas gestadas con la industrialización del siglo XX. En sus orígenes es una disciplina que surge en el conflicto entre atender los procesos de los sujetos y las necesidades de las instituciones y de los sistemas sociales.
De esta manera el campo se desarrolla en América Latina desde dos vertientes: la que impulsan los ministerios de educación, apoyados en la ideología de la OCDE y de su prueba PISA impulsando el logro resultados homogéneos y la que desarrollan algunos (pocos) investigadores en el campo del currículo con relación a alguna de las líneas diversas de debate.
Otro problema emerge con el empleo de la perspectiva eficientista-curricular el desplazamiento genérico del pensamiento pedagógico en la región. Los sujetos de la educación dejaron de importar, lo relevante es impulsar que todos logren aprendizajes similares. La homogeneidad por encima de todo.
Imposible dar cuenta de todo ello en un ensayo, pero se hace necesario ir avanzando en este tipo de indagaciones.

Published: January 2021

The Miño River is one of the main Atlantic basins of Iberia and preserves extensive Pleistocene deposits. However, there is presently limited information concerning the first human occupation history of this region. Existing research undertaken across the region has identified a significant number of Large Flake Acheulean (LFA) sites with African affinities. These sites are associated with former fluvial environments and are now preserved as a sequence of fluvial terraces along the Miño River, located between relative elevations of + 40 m and + 20 m, and dated to between Marine Isotope Stages (MIS) 9 and 6. The chronological range and observed technological patterns are similar to those recognised in other areas of South western Europe, particularly the central Iberian Peninsula and Aquitanian region (France) during the second half of the Middle Pleistocene.
Nutrient and anti-nutrient composition of processed crayfish (Atya gabonensis) from river Benue, Nigeria.
Authors: Iwar Micheal , Amu Comfort Msurshima 
Published: January 2021

The species of crayfish identified as (Atya gabonensis) along River Benue Nigeria and were captured and analyzed for nutrient and antinutrient content including, proximate composition (crude protein, crude fat, crude fiber, ash, and moisture content), as well as vitamin A, Vitamin B components, Vitamin C, Vitamin D, vitamin E, Vitamin K and select mineral concentrations. Additionally, some important antinutrients in crayfish were also examined. The proximate composition showed that moisture content was (9.54%), protein was (7.46%), Crude fibre was (5.60%), fat was (1.57%) and ash was (2.47%) respectively. This was found to be rich in protein and considerably high amount of moisture content. The anti-nutrient composition analysis revealed the presence of Saponin (0.471mg/100g), Alkaloid (3.905mg/100g), flavonoid (0.675mg/100g), tannin (0.017mg/100g), Phytate (0.060mg/100g), Oxalate (0.005mg/100g) and others, all of which are below toxic level. For mineral and vitamin compositions, potassium was significantly (P>0.05) higher than iron, zinc, magnesium, calcium and phosphorus while vitamin C was (4.920mg/100g) which is higher than all other vitamins evaluated. Based on these findings crayfish (Atya gabonensis) is recommended for consumption and for further investigation as a potential raw material for the pharmaceutical industry.Keywords: Atya gabonensis, Nutrient, Anti nutrient, River Benue,composition

AbstractH2 adsorption on Au catalysts is weak and reversible, making it difficult to quantitatively study. We demonstrate H2 adsorption on Au/TiO2 catalysts results in electron transfer to the support, inducing shifts in the FTIR background. This broad background absorbance (BBA) signal is used to quantify H2 adsorption; adsorption equilibrium constants are comparable to volumetric adsorption measurements. H2 adsorption kinetics measured with the BBA show a lower Eapp value (23 kJ mol−1) for H2 adsorption than previously reported from proxy H/D exchange (33 kJ mol−1). We also identify a previously unreported H‐O‐H bending vibration associated with proton adsorption on electronically distinct Ti‐OH metal‐support interface sites, providing new insight into the nature and dynamics of H2 adsorption at the Au/TiO2 interface.
Untangling the Complexity of Mixed Lithium/Magnesium Alkyl/Alkoxy Combinations Utilised in Bromine/Magnesium Exchange Reactions
Authors: Bole Leonie J. , Judge Neil R. , Hevia Eva 
Published: January 2021

AbstractWhile it is known that the addition of Group 1 alkoxides to s‐block organometallics can have an activating effect on reactivity, the exact nature of this effect is not that well understood. Here we describe the activation of sBu2Mg towards substituted bromoarenes by adding one equivalent of LiOR (R=2‐ethylhexyl), where unusually both sBu groups can undergo efficient Br/Mg exchange. Depending on the substitution pattern on the bromoarene two different types of organometallic intermediates have been isolated, either a mixed aryl/alkoxide [{LiMg(2‐FG‐C6H4)2(OR)}2] (FG=OMe; NMe2) or a homoaryl [(THF)4Li2Mg(4‐FG‐C6H4)4] (FG=OMe, F). Detailed NMR spectroscopic studies have revealed that these exchange reactions and the formation of their intermediates are controlled by a new type of bimetallic Schlenk‐type equilibrium between heteroleptic [LiMgsBu2(OR)], alkyl rich [Li2MgsBu4] and Mg(OR)2, with [Li2MgsBu4] being the active species performing the Br/Mg exchange process.
Foreign exchange rate volatility smiles and smirks
Authors: Choi Sun‐Yong , Kim Jeong‐Hoon , Yoon Ji‐Hun 
Published: January 2021

AbstractWe study the implied volatilities of three foreign exchange (FX) option markets: EUD/USD, GBP/USD, and AUD/USD. We find that they are distinct from each other. The implied volatilities of the EUD/USD market tend to be more U‐shaped than those of other markets. Local volatility models such as the constant elasticity of variance (CEV) model and stochastic volatility models, such as the Heston model, may fail to capture this type of convexity. We choose a stochastic‐local volatility model to obtain an implied volatility formula for the corresponding FX options. The formula is given by the CEV formula with additional terms reflecting the (pure) stochastic volatility nature of FX rates. Based on this result, we show that the stochastic‐local volatility model is a suitable universal choice for the pricing of these FX options.

Published: January 2021

AbstractA versatile peptide‐based toolbox for surface functionalization was established by a combination of a universal material binding peptide (LCI‐anchor peptide) and sortase‐mediated bioconjugation (sortagging). This toolbox facilitates surface functionalization either as a one‐ or a two‐step strategy. In the case of the one‐step strategy, the desired functionality was directly introduced to LCI. For the two‐step strategy, LCI was modified with a reactive group, which can be further functionalized (e.g., employing “click” chemistry). Sortagging of LCI, employing sortase A from Staphylococcus aureus, was achieved with six different amine compounds: dibenzocyclooctyne amine, biotin‐polyethylene glycol amine, Cyanine‐3 amine, kanamycin, methoxypolyethylene glycol amine (Mn = 5000 Da), and 2,2,3,3,4,4,4‐Heptafluorobutylamine. The purification of LCI‐amine sortagging products was performed by a negative purification using Strep‐tag II affinity chromatography, resulting in LCI‐amine conjugates with purities >90%. For the two‐step strategy, the LCI‐dibenzocyclooctyne sortagging product was purified and enabled, through copper‐free azide–alkyne “click” chemistry, universal surface functionalization of material surfaces such as polypropylene, polyethylene terephthalate, stainless steel, gold, and silicon. The click reaction was performed before or after surface binding of LCI‐dibenzocyclooctyne. Finally, in the case of the one‐step strategy, polypropylene was directly functionalized with Cyanine‐3 and biotin‐polyethylene glycol amine.

AbstractMaturation of human‐induced pluripotent stem cells (hiPSCs)‐derived hepatocytes‐like cells (HLCs) toward a complete hepatocyte phenotype remains a challenge as primitiveness patterns are still commonly observed. In this study, we propose a modified differentiation protocol for those cells which includes a prematuration in Petri dishes and a maturation in microfluidic biochip. For the first time, a large range of biomolecular families has been extracted from the same sample to combine transcriptomic, proteomic, and metabolomic analysis. After integration, these datasets revealed specific molecular patterns and highlighted the hepatic regeneration profile in biochips. Overall, biochips exhibited processes of cell proliferation and inflammation (via TGFB1) coupled with anti‐fibrotic signaling (via angiotensin 1‐7, ATR‐2, and MASR). Moreover, cultures in this condition displayed physiological lipid‐carbohydrate homeostasis (notably via PPAR, cholesterol metabolism, and bile synthesis) coupled with cell respiration through advanced oxidative phosphorylation (through the overexpression of proteins from the third and fourth complex). The results presented provide an original overview of the complex mechanisms involved in liver regeneration using an advanced in vitro organ‐on‐chip technology.
Rapid determination of 20 bile acids in human serum by ultra performance liquid chromatography–tandem mass spectrometry

Published: January 2021

AbstractA method was established for the simultaneous determination of 20 kinds of bile acids in human serum employing ultraperformance liquid chromatography–tandem mass spectrometry. Chromatographic conditions and sample preparation were optimized to achieve good separation and maximum sensitivity for these analytes. The linearity, accuracy and repeatability of the development method were validated with a series of experiments. Under the optimum conditions, good linearities were achieved in the quantitative range for each bile acid with the correlation coefficients (r2) >0.9901. The limit of detections (signal–noise ratio 3) of the method were in a range from 0.02 to 0.57 nmol/L. The recoveries were in the range of 88.1–109.9%, RSD < 6.12%. This method was successfully applied for the determination of bile acids in a human serum sample with simple operation, high sensitivity and good accuracy, and provides a reference for the clinical determination of bile acid content.
Transition towards and of sustainability—Understanding sustainability as performative
Authors: Hallin Anette , Karrbom‐Gustavsson Tina , Dobers Peter 
Published: January 2021

AbstractOur purpose is to explore the concept of “sustainability” when understood from a performative perspective, i.e. as a concept that is filled with meaning across time. Drawing on a 10 year‐long study of the digital footprint of Stockholm Royal Seaport, claimed to be northern Europe's largest sustainable urban development district, we show that “sustainability” emerged as the project became associated with particular places, projects, histories, and technologies. This means that “sustainability” waslocalin that it was situated in the particular spatial context of the project;temporalin that it was situated in a particular time; andpoliticalin that it expressed particular values and perspectives. The study contributes to explaining why “sustainability” remains—and always will remain—a contested concept, which is why sustainability transitions are complex. Consequently, we suggest that the transitiontowardssustainability always involves the transitionofsustainability, something that needs to be acknowledged in order for a transition to actually become sustainable.

Published: January 2021

AbstractAn innovative current measurement method in power systems has attracted more attention from both the industry and academia. Nevertheless, students can feel challenged when assigned to learn new concepts with the currently already difficult engineering courses. Therefore, in this paper, a training platform is designed based on finite element analysis simulation and laboratory experiments. With this training platform, simple and effective simulations and experiments can be performed. In addition, extended applications of this training platform are presented such as design of the magnetic shielding structure, magnetic flux density visualization and calculation of overhead power lines. This design can help engineering students to better understand the application of electromagnetics and the novel current measurement research field.
