Pedro Henríquez Ureña y la Utopía de América: exilios, humanismo y educación
Authors: Southwell Myriam
Published: December 2020

El intelectual dominicano Pedro Henríquez Ureña (1884-1946) vivió una diáspora producto de las agresivas pol.ticas norteamericanas y la conflictividad pol.tica en América Latina. En su tránsito por diferentes países aportó su perspectiva de problemática latinoamericana y los debates sobre la identidad autónoma y la conflictividad ante la necesidad de expandir las prácticas democráticas en la formación. Sus ideas tuvieron especial influencia en la educación universitaria y secundaria a través de una obra lingüística caracterizada por el hispanoamericanismo y una labor de creación de una visión de la historia lingüística de América incluyendo variedades americanas, que reconocía sus raíces peninsulares. El artículo busca recuperar su vitalidad intelectual y su entusiasmo humanista que cultivó en diversas universidades de la región.

Published: December 2020

Purpose: Traditional Chinese Medicines (TCMs) has been officially approved for chronic hepatitis B infection treatment in China. Correct syndrome differentiation is the key prerequisite for rational prescribing TCMs. Unfortunately, TCM physicians have scarcities of objective measures for syndrome differentiation and their diagnosis exclusively relies on individual experience. This study aimed to find out some objective parameters to aid syndrome differentiation. Methods: Three commonly encountered clinical syndromes named accumulated dampness-heat syndrome (ADHS), spleen deficiency with liver depression (SDLD) and blood stasis vessel obstruction syndrome (BSVO) were selected. 64 qualified patients with definite syndromes were enrolled and their plasma amino acids and lipids were profiled by metabolomics analysis. Additionally, their routine clinical laboratory parameters were also collected. Results: Through orthogonal partial least squares-discriminant analysis, the three syndromes could be properly differentiated. The differential parameters between every two syndromes were screened out. Most of them were of the small molecular metabolites. A distinct difference was found between ADHS and the other two syndromes. BSVO and SDLD showed relatively less discrepancy. Furthermore, it was deduced that sphingomyelin metabolism might dominate ADHS phenotype, and platelet functions might affect SDLD phenotype to some extent. Conclusions: These findings provided primary evidence for the objective classification of varied syndromes of chronic hepatitis B patients and proved that metabolomics analysis might be a valuable tool to aid syndrome differentiation in some circumstances.
Electrical response hysteresis of crayfish photoreceptors to light intensity. Dependence on circadian time.
Authors: Barriga-Montoya Carolina , Gomez-Lagunas Froylan
Published: December 2020

We studied the light-triggered current of crayfish photoreceptors. We found that when a train of light flashes of either increasing or decreasing intensity is applied, the current waveform presents the non-linear behavior known as hysteresis. Additionally, we observed that the extent of this response depends on the circadian time at which the pulses are applied. We hypothesize that positive feedback loops of biochemical networks underlying light energy transduction are responsible of the observed behavior. It has been demonstrated that a dynamical system hysteresis provides a mechanism that enhances its robustness against random perturbations. Taking into account this characteristic we hypothesize that the electrical-response hysteresis of crayfish photoreceptors: 1) makes the visual system more stable to environmental noise, and hence 2) adds stability to circadian clock oscillations.

Published: December 2020

The study regarding the regularity of changes in the hydrodynamic processes in the area of a sudden expanding in hydraulic section of the planeparallel full pipe flow of the liquid is carried out on the basis of the equations on the boundary layer. A method has been developed for determining the changes in the hydrodynamic parameters of the flow in the transition section which makes it possible to obtain the profile of the distribution of fluid velocities in any cross section of the channel based on the results of deformation of the areas of velocity under common initial and boundary conditions. The hydrodynamic processes occurring on transition of sudden expanding on hydraulic section of plane-parallel full pipe flow are studied in cases when: a) the velocity at any point of the inlet section of the channel is constant; b) the velocity at the inlet section is distributed according to the parabolic law. The calculation results for various values of the coefficient of expansion are given: Based on the results of computer simulation, the course of deformation of the velocity diagram along the length of the transition section was obtained for a constant and parabolic distribution of the velocities of the fluid flowing into the expanded section of the channel. The regularities of pressure distribution along the length of the studied section were also determined.

El objetivo de esta investigación fue estudiar psicométricamente una medida de parentalidad percibida adaptable a las configuraciones familiares actuales y a los objetivos de investigación vigentes en el área. Para ello se analizó una muestra de adolescentes (n = 443, MEDAD = 15.49 años, DEEDAD = 1.85, 50.6% varones, 49.4% mujeres) y una muestra de adultos (n = 512, MEDAD = 40.83 años, DEEDAD = 15.05, 49.6% varones, 50.4% mujeres) utilizando un instrumento diseñado especialmente para este fin. Los análisis efectuados derivaron en un instrumento (Escala de Parentalidad Percibida; EPP) de veinte elementos pasible de ser utilizado tanto en adolescentes (EPP-ADO) como en adultos (EPP-ADU) con familias de origen diversas. La medida cuenta con evidencias de validez que fundamentan su estructura bidimensional en todas sus versiones y que habilitan a estudios comparativos de los resultados obtenidos con las mismas. Además, los análisis con distintos criterios externos replican los resultados comúnmente hallados cuando se analiza la parentalidad percibida en relación con la sintomatología psicológica, el bienestar y los estilos de afrontamiento. Se proveen baremos para su transferencia al ámbito de aplicación. Mediante la EPP se pueden estudiar las dos dimensiones centrales de la parentalidad (respuesta y demanda) y su combinación en el análisis de estilos parentales tanto en cuidadores primarios como secundarios.

Published: December 2020

El presente trabajo de investigación está enfocado en estudiar el procedimiento de estabilización de suelos arcillosos con cal y determinar el óptimo contenido del estabilizante que asegure un aumento significativo en la capacidad de soporte de la subrasante para pavimentos flexibles. La zona de estudio y de donde se extrajeron las muestras es la localidad de Villa Rica, progresiva 3+000 km de la carretera Oconal-Cedropampa. La cal como agente estabilizante tiene propiedades de absorción de agua y mejora la resistencia de suelos arcillosos mediante el encapsulamiento de partículas de arcilla. Es decir, al interactuar cal con partículas de arcilla se produce un efecto de floculación, creando una doble capa difusa que reduce el potencial de hinchamiento y expansión de los suelos finos y aumentando la resistencia a la penetración. Se realizaron ensayos de granulometría, límites de consistencia, gravedad específica, proctor modificado y el ensayo de CBR para muestras del suelo en estado natural y con porcentajes de 9 %, 15% y 21% de cal. También, se realizó la clasificación de suelos mediante el método AASHTO Y SUCS para complementar los cálculos necesarios. El porcentaje óptimo de cal hallado fue 15%, con lo que se logra incrementar el valor del CBR del suelo de 3.3% a 5.9%.Además, se realiza un análisis comparativo de costos del diseño de la estructura de pavimento. En donde, se modela el pavimento sobre una subrasante en estado natural y otra en estado mejorado con el óptimo porcentaje de cal hallado.

Published: December 2020

La presente investigación analiza las condiciones de tráfico vehicular actual en dos intersecciones de la avenida Javier Prado Oeste, tramo Calle Las Flores & Calle Las Palmeras, en el distrito de San Isidro. La investigación empieza con la descripción de los problemas existentes en las intersecciones, como la deficiente programación de semáforos, falta de semáforos coordinados e incompatibilidad entre controladores semafóricos. El análisis de la investigación se realizó en base a un modelo microscópico, desarrollado con apoyo del software Vissim. El proceso de construcción de ambos modelos consiste en cuatro fases. La primera fase es el trabajo previo, en la cual se realizó la recolección de datos de campo. En segundo lugar, se encuentra la construcción de los modelos mediante el programa. En tercer lugar, se realizó la calibración y validación de ambos modelos en base a parámetros psicofísicos y estadísticos GEH para certificar que los resultados del modelo se asemejen a las condiciones actuales de las intersecciones. Por último, se incorporaron los nuevos flujos futuros en los modelos cada 15 minutos los cuales se simularon, evaluaron y compararon con los niveles de servicio obtenidos con las intersecciones proyectadas que incorporan la propuesta de mejora. Esencialmente los niveles de servicio de las intersecciones mejoran incorporando la propuesta de semáforos inteligente por medio de la optimización de ciclos semafóricos con el programa Synchro 10.0, esto se deduce a partir de la disminución de longitudes de colas en todos los accesos y la reducción de demoras de viaje en ambas intersecciones.

Esta tesis fue estructurada con el fin de crear una nueva experiencia vivencial que brinde una mejor calidad de vida a mujeres diagnosticadas con cáncer de mama. Por esta razon, se propone romper con el típico concepto de un Centro de Rehabilitación y aportar con el desarrollo de una nueva estrategia de gestion interna de manera que el sistema sea tan flexible como las necesidades de las pacientes en tiempo real. Otro de los propósitos de este proyecto es que pueda ser ejecutado con el apoyo de una ONG y así, de la mano de psicologos especialistas en transtornos por cáncer de mama, expertos en nutricion y rehabilitacion física unir idea junto a especialistas en paisajismo, infraestructura y diseño. De esta manera poder desarrollar un modelo operativo funcional que rehabilite tanto directa como indirectamente a las pacientes desde su ingreso al centro. Para este proyecto, en primer lugar, se realizó un estudio sobre los efectos y consecuencias del cáncer de mama, así como también los posibles tratamientos para el proceso de rehabilitación independientemente de cada diagnostico u estadio. Debido a que en el país no existe un Centro de Rehabilitación Física y Psicológica para Mujeres con Cáncer de Mama, se realizó el análisis de su arquitectura, experiencia y funcionalidad de las instituciones existentes con el mismo objetivo en países como España, Colombia y Argentina. De esta manera se obtuvo la información necesaria para ejecutar un sistema estructurado por cada especialidad propuesta en esta tesis, fusionando el diseño interior y arquitectura con en el rubro de la medicina. En segundo lugar, se analizó la ubicación y perimetros a la redonda de la vivienda elegida donde se desarrollará el proyecto para posteriormente hacer una intervención estructural y seguidamente el diseño de cada ambiente de manera que puedan satisfacer las necesidades de nuestro público objetivo. Finalmente se plantea las conclusiones en relación con los objetivos propuestos en el inicio del proyecto.

The article is devoted to the results of the study of the mineral and isotopic composition of speleothems of the of the Kholodnyy Grotto cavein the Bzyb gorge of Abkhazia. The cavity was mapped and various types of secondary mineral deposits were recorded. The following mineral formations (speleothems) have been established in the cave: Mondmilch, corallites, guhrs, carbonate breccias, biogenic phosphates. Attention is drawn to the abundance of allogeneic mineral inclusions in drip calcite associated with the weathering products of igneous rocks (zircon, potassium feldspar, ilmenite, rutile, monazite, apatite). The source of these minerals is presumably the weathering crust of the Middle Jurassic volcanics. The oxygen isotope composition of all studied carbonates reflects the participation of meteoric waters. Moreover, the isotopic composition of carbon is subject to significant variations associated with kinetic fractionation (CO2 degassing). Based on the results of petrographic and isotopic studies, an attempt was made to typify speleothems according to the nature of their feeding and the characteristics of crystallization. Also, the cave revealed phosphate mineralization in the form of dark brown thin-layered crusts of hydroxylapatite, formed in place of old guano deposits.

Published: December 2020

Massive open online courses (MOOCs) are an important approach for achieving UNESCO’s aim of open and accessible education. However, there are concerns regarding fragmentation or bias of MOOCs toward certain disciplines or countries. This study sought to: (a) examine how MOOCs research has evolved and is distributed, (b) determine what key areas are discussed in MOOCs research, and (c) identify the major players in MOOCs research and their collaborations. This study conducted a bibliometric analysis of 3,118 scholarly works related to MOOCs as recorded in the Scopus database in July, 2019. Specifically, we analyzed the evolution of MOOCs research by examining (a) published studies, (b) source titles, (c) types of sources and documents, as well as (d) the languages in which the documents were written in. We further analyzed the key areas of MOOCs research by looking into common subject areas, keywords used most often, and title analysis. Finally, we sought to increase our understanding of the major players in MOOCs research and their collaborations by examining (a) which countries contributed most to MOOCs research, (b) the main institutions involved, as well as (c) authorship and citation analysis. Findings indicated that in their early development starting in 2009, MOOCs caught the attention of scholars from both the East and the West, and the number of publications grew consistently over the 10 years after that. MOOCs research has been well distributed but has yet to adequately encourage inclusiveness. There has been healthy cross-country collaboration, but there is a gap in MOOCs research originating from certain countries as compared to the rest of the world. Our findings provide important input towards improving the inclusivity and global reach of MOOCs.

Published: December 2020

This study aims to understand factors that affect the behavioural intention of manufacturing engineers in Malaysia to use e-learning in the workplace. Two hundred usable online questionnaires were collected from respondents who were engineers in Malaysian manufacturing companies. The data were analyzed using SPSS and Smart PLS version 3.2.6. Results supported all direct relationships except for the influence of prior experience in perceived ease of use. Interestingly, perceived usefulness and perceived ease of use fully mediated between computer self-efficacy and behavioural intention to adopt. The study provides theoretical implication to the technology acceptance model by confirming the mediating role of perceived ease of use and perceived usefulness in the context of a manufacturing setting in an emerging market. In practical terms, the study provides insights to guide organizations in designing e-learning systems that are well-received by employees at the workplace.

Ha csak az alappontokban ismert magasságot vesszük figyelembe, akkor kizárólag a háromszögenkénti síkillesztés jöhet szóba, mint folytonos véges elem interpoláció. Lokális szélsőérték (minimum vagy maximum) pontok keresésekor a síkillesztés csak az alappontokban találhat extrémumot, a lefedő háromszögeken belül nem. Ezen javítandó olyan háromszögenként bikvadratikus véges elem felületinterpolációt dolgoztunk ki, mely nemcsak az alappontokra illeszkedik, hanem bizonyos parciális deriváltakra is, és folytonos a határoló éleken. A megvalósításhoz kétféle becslést használtunk a parciális deriváltak kiszámításához.

The purpose of this study is to examine the impact of conflict of interest to the level of IPO price determined by managers. This experiment divides treatment group (the group of participants who have economic benefit from their decision making), and control group (groups with no economic benefit from their decision making). In experiment scenario for treatment group, the managements of IPO companies tend to decrease the price of IPO in order to get financial benefit. Using experimental design, this research shows that participants in treatment group determine lower IPO price than control group. This evidence confirms IPO phenomenon around the world. This research also makes supplementary analysis. The results show that alternative statistical test using GPA and gender of participants as control variable are not statistically significant. It means that the level of IPO price isn’t determined by GPA and Gender, but conflict of interest.

An Analysis of Paratexts in the (Re)translations of Oliver
Twist into Croatian
Authors: Badić Edin
Published: December 2020

The aim of the present study is to analyse paratextual elements in Croatian (re)translations of Charles Dickens’ classic social novel Oliver Twist; or, The Parish Boy’s Progress (1837–1839). We will explore the level of paratextual (in)visibility of translators in the (re)translations of Oliver Twist and observe how their (in)visibility might affect the reading and interpretation of the novel. The fact that Oliver Twist has been on the reading lists for Croatian primary schoolers ever since the early 1950s may account for the intense interest in the novel on the part of Croatian publishers. The first edition of Oliver Twist into Croatian appeared in 1901 and, since then, three (re) translations have been published, as well as a large number of reprints. The findings aim to contribute to a better understanding of Croatian translation history, shedding light on different approaches to translating children’s literature and the effects such translation practices may have had on the expectations of the target readership.
Picturebook Format
Authors: Ramos Ana Margarida
Published: December 2020

The purpose of this paper is to present picturebooks as a special format instead of a literary genre, due to the growing relevance of book design and peritextual elements in defining the characteristics of this art form. The creative investment in the peritexts has implications in the construction of the message and in the reading process, creating an original artefact. The paper also describes different types of picturebooks and explores the influence of the picturebook format on other genres, underlining its importance in contemporary Portuguese publishing.

Fresh water resources in terms of water quality is a crucial issue worldwide. In Egypt, the Nile River is the main source of fresh water in the country and monitoring its water quality is a major task on governments and research levels. In the present case study, the physical, chemical and algal distribution in Nile River was monitored over two seasons (winter and summer) in 2019. The aims of the study were to check the seasonal variation among the different water parameters and also to check the correlations between those parameters. Water samples were collected from the Nile in Cairo governorate in EGYPT. The different physiochemical and microbiological properties in water samples were assessed. The studied parameters were included: temperature, turbidity, dissolved oxygen, chemical oxygen demand, pH, electric conductivity, total dissolved solids, total hardness, anions and cations. Also, the total algae count, blue-green algae, green algae, diatoms, unicellular and filamentous algae were monitored. The results revealed that during winter season the values recorded for (turbidity, total dissolved solids, pH, total alkalinity, total hardness, dissolved oxygen, chemical oxygen demand as well as nitrate, sulfate, chloride, fluoride ions, calcium and magnesium) were higher than during summer. While other parameters including ammonia, nitrite, silicate, carbon dioxide, phosphate, manganese, iron and residual aluminium were higher in summer compared to winter. The data showed a variation total algal count of 4600 to 6500 unit/ml in winter and varied from 3100 to 4500 unit/ml during summer season with predominance of diatoms. The recorded Pearson’s correlations indicated several significant correlations between tested parameters. In conclusion, although there were several variations in tested water quality parameters though all results were within the permissible limits set by the World Health Organization for drinking water.

Published: December 2020

In this work, a simulated study was carried out for designing a novel spiral rectangular patch of microstrip antenna that is used in ultra-wideband applications by using a high frequency structure simulator software (HFSS). A substrate with dielectric constant of 4.4 and height 2.10 mm (commercial substrate height available is about 0.8-1.575 mm) has been used for the design of the proposed antenna. The design basis for enhancing bandwidth in the frequency range 6.63 - 10.93 GHz is based on increasing the edge areas that positively affect the antenna's efficiency. This design makes the designed antenna cost less by reducing the area of the patch. It has been noticed that the bandwidth of the antenna under this study is increasing to 4.30 GHz or 61% compared with 3.6% for the standard rectangular microstrip antenna with the same dimensions of the proposed antenna. The antenna also maintains the voltage standing wave ratio of 1.09 at resonant frequency 7.07 GHz, return loss -27.07 dB, and the amount of impedance in real and imaginary parts 51.5Ω and 3.3Ω, respectively.

BackgroundThe occurrence of skeletal metastases of unknown primary origin (SMUP) is uncommon. To provide appropriate treatments for the primary and metastatic lesions, early diagnosis of the primary origin of SMUP is important. Therefore, this study aimed to assess the types of examination method effective in diagnosing the primary origin of SMUP and their order in terms of efficacy.MethodsWe retrospectively examined 63 patients with SMUP. The primary origin was examined via physical examination, blood test including tumor markers, chest radiography, thoracoabdominal computed tomography (CT) scan, positron emission tomography (PET)-CT scan, metastatic lesion biopsy, and other assessments. Examination methods considered effective for the diagnosis of the primary origin in a specific type of cancer were investigated.ResultsThe lung was the most common primary origin, followed by the lymph nodes, prostate, and breast. Meanwhile, biopsy (87.0%) was the most effective examination, followed by PET-CT scan (60.0%) and thoracoabdominal CT scan (38.6%). The first four steps; physical examination, blood tests, chest radiography, thoracoabdominal CT were effective in diagnosing the primary origin in 41 (65%) of 63 patients. Finally, four patients were diagnosed with SMUP.ConclusionsThe examination steps used in this study are effective in diagnosing the primary origin of SMUP during the initial visit. Blood tests are useful for hematological malignancy and prostate cancer. CT scan can be used to identify cancers in the lung, breast, and kidney, which are the common primary origins. Moreover, it is more useful than PET-CT scan from a comprehensive perspective.
