Prevalence of Substantive Policy in American Presidential Inaugural Addresses
Authors: Parco Andrew
Published: March 2020

The inaugural address is the starting line of a four-year marathon, a bold declaration of ambitions outlined on the campaign trail looking to be crystallized into concrete policy. Presidents streamline their own national visions into a single, cohesive address and distill their proposals into rallying cries for the American people. But how does the subject matter of inaugural addresses predict or indicate with a presidential administration’s later priorities and accomplishments? This study seeks to investigate this question by performing a content analysis of a stratified random sample of presidents. It develops a coding scheme and creates 12 categories that presidents have and could discuss in their inaugural addresses. It analyzes each of the chosen presidents’ inaugural addresses and subsequent State of the Union addresses, identifying substantive policy issues and recording an approximate word count for each one. After calculating the word count for each category in all of the selected inaugural addresses and States of the Union, the categories and word counts will be ranked for each individual speech. The rankings will then be compared between the two with a one-ranking margin of error. All of this data seems to preliminarily indicate that issue replicability is increasing over time, but magnitude replicability is much more variable. Therefore, it can be concluded that inaugural addresses are not likely to contain substantive policy that will affect the priorities and accomplishments of a president’s administration.
Associated Risk Between Use of Oral Contraceptive Pills and Three Types of Breast Cancer: ER+, ER-, and TN
Authors: Rangaswamy Roshni
Published: March 2020

Around 9.5 million women between the ages of 15 and 44 use some form of oral contraceptives. Oral contraceptive pills typically consist of progestin and estrogens, synthetic versions of the hormones that a female-bodied person naturally produces and are used by many people for a various number of reasons; such reasons include regulating acne, controlling hormone production, and preventing pregnancy. One in eight women in the US is diagnosed with breast cancer over the course of her lifetime, and many of these cancers have hormone-related causes. However, there are three types of breast cancer specifically linked to the hormones that are found in oral contraceptive pills: estrogen receptor-positive, estrogen receptor-negative, and triple-negative. While the potential of oral contraceptive-related causes for these breast cancers have been studied at great length, researchers are often unable to confirm their finding of an associated risk between synthetic hormones in oral contraceptives and certain types of breast cancer. Many studies agree that this associated risk exists, but stress the need for more involved research with more detailed and specific objectives. This literature review will provide insight into limitations of current research on the associated risk between oral contraceptives and breast cancer in order to fill research gaps and evaluate the certainty of current findings.
Understanding the Challenges Faced by Child-Focused Civil Society Organizations in Ho Chi Minh City
Authors: Morrone Annalise
Published: March 2020

The presence of an active civil society is one of the most integral parts of progressive and productive community development. Within the past two decades civil society organizations have grown in size and scope throughout Viet Nam. This has been in an attempt to offset the divestment of international aid networks and match the rapid economic development occurring in urban centers like Ha Noi and Ho Chi Minh City (HCMC). The prospect of high paying jobs resulting from increased domestic and foreign investment in urban areas has encouraged rapid rural-urban migration within HCMC. As a result, urban poverty is on the rise in HCMC and the children of these vulnerable populations face unfavorable odds in educational, emotional, and legal support. The civil society organizations discussed in this paper aim to fill these gaps by supporting children in need in HCMC. However, this research finds that organizations lack sustainable funding networks, autonomy, and human resources. To ensure that their practices persist, government policy must be implemented to encourage a culture of domestic charity from individuals and businesses, as well as assist these organization’s capacity building measures.

Published: March 2020

Isolated hepatocytes can be obtained from the liver by collagenase infusion, a procedure that could affect cell isolation as well as the integrity of membrane receptors. In this respect we compared metabotropic glutamate subtype 5 receptor (mGluR5) protein expression and activity in rat hepatocytes isolated by two collagenases, type I and type IV. Hepatocytes were isolated from male Wistar rats (200-250 g) using collagenase I or collagenase IV and after isolation, viability and morphology of rat hepatocytes were assessed measuring mGluR5 protein expression by Western blot analyses. mGluR5 activation was evaluated by inositol-1-phosphate (IP-1) accumulation after treatment with the mGluR5 orthosteric agonist ACPD or the selective antagonist MPEP. No difference in cellular viability and morphology was observed using collagenase I when compared with collagenase IV. An increase in mGluR5 protein expression was observed in hepatocytes isolated using collagenase IV with respect to collagenase I. Moreover, hepatocytes treated with ACPD and with MPEP presented higher levels of IP-1 when isolated using collagenase IV compared to collagenase I. These results indicate that collagenase IV better preserves the activity of surface proteins such as mGluR5 in isolated rat hepatocytes, an in vitro model useful to reduce the use of experimental animals, in line with the 3R ethical framework.
DALLE ESIGENZE ENERGETICHE SULLA TERRA ALLâ€™ESPLORAZIONE DI MARTE PASSANDO PER I COLORI DELLA CAPPELLA SISTINA: PRESENTE E FUTURO DEL FOTOVOLTAICO E DEI COMBUSTIBILI SOLARI
Authors: Abbotto Alessandro
Published: March 2020

The challenge of renewable energies has now come to a strategic step. While 80% of the energy still comes from fossil fuels, the role of renewable energies is in constant growth. The challenge of renewables is not only a technological transition, but also the indispensable response to the needs of the planet, from the incessant demographic growth to climatic emergencies and to the development of the poorest countries, and eventually to medium to long term challenges such as the colonization of Mars. Researchers are therefore committed to developing innovative, clean and efficient solutions to meet such challenge. In particular, organic dyes, organic molecules such as those founds in drugs or liquid crystals, represent key actors of one of the most fascinating chemistry frontiers to produce low cost and clean renewable energy. As the true colors of the Sistine Chapel frescoes, wanted by Michelangelo, have now emerged and visible to everyone, also in this field only specific colored dyes are able to address effectively the energy challenge. The scientist, especially the chemist, starting from the state of the art and innovation, is engaged in the design of new molecules owning the correct colors.
A HOLISTIC APPROACH TO THE SPACE DEBRIS MITIGATION
Authors: Rossi Alessandro
Published: March 2020

The space activities in almost every orbital regime are now jeopardized by the continuous growth of the space debris populations. To prevent the proliferation of the space debris in Earth orbit it is necessary to tackle the problem from dierent perspectives, exploiting the latest theoretical and experimental knowledge in dierent elds, such as astrodynamics, spacecraft engineering and legal studies, to address four main pillars: prevention, protection, mitigation and regulation. In this respect the European Community nanced a large H2020 project named ReDSHIFT whose goal is to nd passive means to mitigate the proliferation of space debris. A short summary of the project and of its main ndings is given in the paper, with particular emphasis on the more theoretical part, related to the simulation of long term evolutionary scenarios of the whole space debris environment and to the mapping of the Low Earth Orbit phase space, looking for passive dynamical de-orbiting solutions.
Sustainable provision of raw water based on the management of ecosystem services in small watersheds
Authors: Bueno Mateus Marques , Valcarcel Ricardo , Pereira Marcos Gervasio , Mateus Felipe Araújo
Published: March 2020

The differentiated effects of the provision of environmental services in a watershed are due to the capacity of regularization of outflows in its mouth. In impacted areas, this environmental function is affected, and in some situations, it ceases to exist completely. This study characterized the soil and the production of sediments in anthropic watersheds, with the purpose of describing and evaluating the environmental services offered by a watershed undergoing anthropic transformation. The analyses show that the water flow in the remaining watersheds was preferably horizontal in the transmission zone, and these areas represent almost all areas. The values of hydraulic conductivity suggest that the infiltration decreases with soil depth; this fact is corroborated by the values of bulk density. The natural regions of water accumulation, the floodplains or outcrops zones, are small and do not have direct contact with the main floodplain present in the Guandu River Basin, making it impossible to recharge through other areas. Even so, water balance shows that the set of measures implemented ensured that the deficit water demand was supplied during the years of operation, even in times of water deficit. Likewise, the retention of solids in the settling tanks and in the drainage system prevented some 29,000 t of sediment from being carried between the years of 2012 and 2015.

Background and aims – Located in the transition zone of Guineo-Congolian and Zambezian phytochoria, the Angolan provinces of Uíge and Cuanza Norte are of particular interest for floristic studies and high biodiversity is expected. Nevertheless, explorations of the vegetation are relatively rare. Our study aims to supplement a recent checklist of vascular plants of Angola. Methods – Data were collected during 17 field trips between 2013 and 2018, during which herbarium specimens were prepared for later identification of plant species. The results were compared with the current checklist as well as with other floristic works, herbarium collections and online databases relevant for the region.Key results – We document 20 new records of indigenous vascular plant species for the flora of Angola (19 species and one subspecies), including four new generic records. Furthermore, nine alien species are added to the checklist of the flora of Angola.Conclusion – Our results confirm that the flora of northern Angola is composed by elements of various adjacent areas. However, not all species present are known yet. Further botanical investigation is needed to complete our floristic knowledge of the region.

Abstract. Nuclear magnetic resonance imaging (MRI) has became an unavoidable medical tool in spite of its poor sensitivity. This fact motivates the efforts to enhance the nuclear magnetic resonance (NMR) probe performance. Thus, the nuclear spin excitation and detection, classically performed using radio-frequency coils, are required to be highly sensitive and homogeneous. The space harmonics suppression (SHS) method, already demonstrated to construct coil producing homogenous static magnetic field, is used in this work to design radio-frequency coils. The SHS method is used to determine the distribution of the electrical conductive wires which are organized in a saddle-coil-like configuration. The theoretical study of these SHS coils allows one to expect an enhancement of the signal-to-noise ratio with respect to saddle coil. Coils prototypes were constructed and tested to measure 1H NMR signal at a low magnetic field (8 mT) and perform MRI acquired at a high magnetic field (3 T). The signal-to-noise ratios of these SHS coils are compared to the one of saddle coil and birdcage (in the 3 T case) of the same size under the same pulse sequence conditions demonstrating the performance enhancement allowed by the SHS coils.
Velocidad de procesamiento en la comprensión morfológica de verbos en niños preescolares con trastorno específico del lenguaje y su relación con el control inhibitorio
Authors: Urrutia Martínez Mabel , Roa Inostroza Miriam Alejandra
Published: March 2020

En el último tiempo se ha estudiado la relación del trastorno específico de lenguaje con algunas funciones cognitivas como memoria, atención y funcionamiento ejecutivo, pero pocos estudios en español han investigado la relación de variables psicológicas y lingüísticas en su conjunto. El objetivo de este estudio fue observar la relación entre aspectos cognitivos y lingüísticos, abordando los problemas gramaticales del trastorno específico de lenguaje, específicamente la comprensión morfológica de verbos y el tiempo de reacción en el procesamiento de tales tareas. Los participantes fueron niños y niñas hispanohablantes monolingües con diagnóstico de TEL en el periodo preescolar y un grupo control. A través de un diseño experimental se midió el tiempo de respuesta y la cantidad de aciertos go/no go en el procesamiento de aspectos morfológicos verbales. Tales medidas se relacionaron con el uso de algunas covariables como la inhibición conductual en una tarea no verbal, la velocidad de denominación a nivel de producción lingüística y la memoria de trabajo visual, a partir de una evaluación neuropsicológica. Los resultados mostraron que los niños con TEL se demoraron más tiempo en la identificación de verbos irregulares en comparación con los verbos regulares y un mayor tiempo en la identificación de verbos en tiempo pretérito perfecto simple que verbos en tiempo presente, en comparación con el grupo control. En cuanto al control inhibitorio, los niños con TEL obtuvieron una mayor tasa de errores en tareas de inhibición en comparación con el grupo control y mayor tasa de errores en la comprensión de ambos tipos de verbos y ambos tiempos verbales.
Hacia una caracterización lingüística contemporánea de las afasias propuestas por A. R. Luria
Authors: Guillén Escamilla Josaphat Enrique
Published: March 2020

La tipología lingüística de Jakobson (1971a) –a partir de la clasificación de Luria (1947)– sigue siendo el análisis más exhaustivo sobre las alteraciones del lenguaje que se presentan en la afasia; no obstante, hay que considerar que esta caracterización se encuentra limitada al desarrollo de la teoría lingüística de su época, por lo que las referencias a aspectos pragmáticos y discursivos son escasos. Por tal motivo, este trabajo tiene dos objetivos: (i) describir la teoría neuropsicológica de Luria, en especial los conceptos de factor neuropsicológico y organización dinámica de las funciones para señalar el papel que desempeñan dentro de las alteraciones sistémicas en el lenguaje, y (ii) actualizar la caracterización lingüística de Jakobson sobre los seis tipos de afasia de Luria, agregando descripciones pragmáticas y discursivas. Finalmente, se destaca que una perspectiva funcional en el estudio de las alteraciones del lenguaje permite distinguir entre déficits pragmáticos de base gramatical y déficits específicamente pragmáticos en las afasias (Fernández-Urquiza et al., 2015).

Published: March 2020

Selecting a strand is a crucial act to every student in such way that they have to considered their financial status, parents and peer suggestion, and also their self-choice in acting on it. This study investigates whether financial status with self-choice; parents influence with self-choice; and peer influence with self-choice are having an association with each other in selecting a strand. 214 of students by complete enumeration answered the questionnaire on financial status and likert-scale for parental influence, peer influence, and self-choice and the data gathered been analyzed via weighted mean, frequency, chi-square and lambda in determining their association. The result shows that the financial status of students in school alone is inclined to self-choice in the selection of a strand but not with parental and peers influence in selecting a strand. In other words, parents and peers show no significant association with self-choice of students, though the influences of parents and peers are noticeable.

Published: March 2020

Notwithstanding the challenges facing the financial markets and the current global economic growth prospects, the listed banks that are operating in healthy situation will remain resilient. The study sought to investigate the financial performance of listed Banks Ghana during the period of 2015 to 2018. Financial ratios were used to assess the financial performance (profitability), liquidity, credit performance and capital structure (capital adequacy). Bar charts and line graphs were used to analyse the panel data and the findings indicate that among ROA, ROE, ROD and NIM, net interest margin (NIM) is the best measure of profitability. The findings of the study also showed that the liquidity position of these banks is very alarming and aggravating as most the banks have poor liquidity issues making depositors vulnerable of losing their investments. The findings again revealed that the credit performance of the banks is very abysmal as a result of ineffective and inefficient credit assessments resulting in bad loans. In evaluating the capital adequacy ratio, it was evident that the banks were highly undercapitalised which vindicates the effort and the stringent measures by bank of Ghana for its intensified regulations. This study suggests managerial and policy recommendations regarding the development and enhancing of some banking operations which will boost the banks' profitability, liquidity, credit performance and improve the capital adequacy challenge for the banks.
“Grotesquery to the Surface”: The Leo Frank Case and Philip Roth’s The Plot Against America Revisited in Trump’s Alt-Right America
Authors: Kaplan Brett Ashley
Published: March 2020

This essay returns to the story of Leo Frank, a Jewish factory owner lynched in 1915 by a mob that catalyzed the regrettable reemergence of the KKK. Philip Roth describes the lynching of Frank in his alternative history, The Plot Against America (2004), and reading the historical event alongside the novel furnishes a means to see how deeply the interconnection between hatreds flows in the United States more than one hundred years later and to help unpack some of what we suffer now. A through-line exists between the KKK then and Trump-era white supremacist groups now. This article contends that while focusing on questions of Jewishness and its representations is crucial, we also need to work cross-racially/culturally in order to understand and thus combat the logics of white supremacy. The case of Leo Frank and the diatribes and hate speeches that ultimately fueled his lynching highlight the long historical imbrication of Blackness and Jewishness in the United States, which then, in turn, fed Nazi propaganda. Understanding what has been unleashed under Trump and exploring ways that Jewish studies scholars can address multiple forms of white supremacy requires an historically informed approach to the concurrent and mutually-fueling rise in racism and antisemitism.

Published: March 2020

Background and aims: Low back pain is mostly due to disc herniation and has a burden upon economy and social aspects of life. Failure to improve after open lumbar discectomy is frustrating. Therefore, identifying predictors of improvement is of great clinical benefit. Aims: This research was conducted to evaluate whether an early exercises rehabilitation program using educational booklet would provide benefit to patients following open lumbar discectomy and determine potential factors of improvement.Patients and methods: Design: Single blind randomized controlled trial. Eighty-eight patients scheduled for open lumbar discectomy from January 2017 to January 2019 at Assiut and Ain Shams Universities hospitals in Egypt were randomly assigned to two groups. Control group (n = 44) received routine postoperative instructions while intervention group (n = 44) received routine instructions in addition to early exercises rehabilitation program and were also provided with a specifically designed educational booklet. Patients were followed up after six months using Oswestry disability index.Results: There was significant improvement among intervention group as compared to control group in several domains of Oswestry disability index (walking, sitting, standing, sleeping, travelling and sexual and social life). Better pre-operative Oswestry disability index score and early application of exercises rehabilitation program using an educational booklet predicted better postoperative Oswestry disability index score after six months.Conclusion: Application of an early exercise rehabilitation program and providing patients with a specifically designed educational booklet would be helpful for patients following open lumbar discectomy. Clinical Relevance: Early exercises rehabilitation program can be used by nursing staff as a reference in management of patients following open lumbar discectomy.
Most Prevalent Study Skills among Taiwanese High School Students with Reference to Gender
Authors: Sasi Abolfazl Shirban , Haga Toshinari
Published: March 2020

This study investigated Taiwanese high school students’ study skills with reference to gender differences. 612 students (358 girls, and 254 boys) from six random high schools in Taiwan participated in this study. A 24-item questionnaire originally developed by University of Houston Clear Lake, Texas was adopted, abridged, and administered. The main focus of the questionnaire was on three study habits/skills constructs of “time management & procrastination”, “study aids & note-taking”, and “organizing & processing information” (eight items each). A Pearson Chi-square test (α ≤.05) was used for each of the 24 items of the questionnaire. The results showed that Taiwanese high school boys and girls have very similar, an even sometimes identical, viewpoints towards study skills. The only significant difference observed in the data analysis in this study were items 1, 5, and 8, suggesting that compared with girls, boys typically care more about time management. Moreover, and based on the rubrics devised by the original instrument developer, it was calculated that the highest difference between boys and girls was .61 “arriving at classes and other meetings on time”, whereas the lowest difference was 0 for “maintaining a critical attitude during study - thinking before accepting or rejecting”. Also, both girls and boys equally seemed to be strongest in “arriving at classes and other meetings on time” (item 1), and weakest in “having a system for marking textbooks” (item 14).

Avanços em computação ubíqua estão permitindo o surgimento de oportunidades em diversas áreas, entre elas está a área da saúde. Nessa área surgem diversas aplicações que possibilitam cuidados ubíquos, chamados de aplicações de U-Healthcare. Um estudo detalhado dos modelos e propostas existentes, mostrou que nenhuma dessas aplicações atende pessoas que sofrem de alergia alimentar. Assim, a proposta desse trabalho é apresentar um modelo ubíquo de detecção de riscos de alergia baseado em ciência de situação, chamado de Allergy Detector. O modelo é focado em alergia alimentar, em particular aos oito principais alergênicos (amendoim, leite, ovo, trigo, soja, peixe, crustáceos e amendoas oriundas de árvores) e seus derivados, responsáveis por 90% de todas as reações de alergias alimentares. Para avaliar o modelo foi desenvolvido um cenário de teste e aplicado em um protótipo que demonstrou a viabilidade da proposta.

The “Internet of Things” (IoT) brings the notion of heterogeneous objects using ubiquitous technologies to interact among them and with the physical environment through technologies such as Bluetooth, ZigBee, GPRS, NFC, QR code, among others. Based on the possibility of linking ordinary objects from the physical world to the Internet, this paper proposes and details a platform called TagHunt, for creating and playing scavenger hunt games. This platform leverages on smartphones’ capability to interact with ordinary objects using IoT-based technologies such as NFC and QR Code, stimulating the player to interact with physical environments looking for “clues” in the game.

Published: March 2020

Social urban sensing is a new paradigm which exploits humancarried or vehicle-mounted sensors to ubiquitously collect data for large-scale urban sensing. A challenge of such scenario is how to transmit sensed data in situations where the networking infrastructure is intermittent or unavailable. In this context, this paper outlines our researches on an engine that uses Opportunistic Networks paradigm to underlie the data transmission of social urban sensing applications. It also applies Situation awareness, Fuzzy Logic and Neural Networks to perform routing, adaptation and decision-making process. We carried out simulations using a simulator environment, achieving positive results. As we know, this is the first paper to use such approaches in Smart Cities area with focus on social sensing application.
Can Summer Philosophy Programs Help Close the Achievement Gap?
Authors: Peterson Bailie ,   Philosophy Documentation Center
Published: March 2020

While summer break presents educational and recreational opportunities for some students, students from depressed socioeconomic groups may face significant obstacles in the summer, including learning loss. In general, these students also lack access to a wide range of intrinsic and instrumental benefits attached to the study of philosophy. While there are currently existing philosophy programs, this contribution highlights the connections between summer experiences and the overall achievement gap, while identifying specific practices shown to yield successful summer programs. Philosophy provides an impressive set of benefits, including academic skills and opportunities for personal growth and development. Incorporating best practices while focusing on the methods and content of philosophy should, therefore, yield particularly rewarding programs. Due to these benefits, summer philosophy programs should be researched, developed, and expanded.
Climate Disruption, Political Stability, and Collective Imagination
Authors: Sandberg Ole Martin ,   Philosophy Documentation Center
Published: March 2020

Many fear that climate change will lead to the collapse of civilization. I argue both that this is unlikely and that the fear is potentially harmful. Using examples from recent disasters I argue that climate change is more likely to intensify the existing social order—a truly terrifying prospect. The fear of civilizational collapse is part of the climate crisis; it makes us fear change and prevents us from imagining different social relations which is necessary if we are to survive the coming disasters and prevent further escalation. Using affect theory, I claim that our visions of the future affect our ability to act in the present. Rather than imagining a terrifying societal breakdown, we can look at how communities have survived recent disasters to get an image of what we need to expand upon to prepare for the future.
Small, rare and little known: new records and species of Cardiomya (Bivalvia: Cuspidariidae) from Brazil
Authors: Carvalho de Lima Tarcilla , Oliveira Cléo Dilnei de Castro , Absalão Ricardo Silva
Published: March 2020

This paper describes rare Cardiomya species from Brazil which have been hitherto misidentified as Cardiomya cleryana (d’Orbigny, 1842) in literature or museum collections. Cardiomya minerva sp. nov. is proposed as new species and is characterized by its quadrangular shell, short and truncated rostrum, and external ornamentation composed of six radial ribs on the posterior half of the shell flank. Cardiomya striolata (Locard, 1897) described from the Mediterranean Sea and northwestern Atlantic Ocean, is reported from Brazil for the first time; although previously regarded as a junior synonym of Cardiomya costellata (Deshayes, 1835), it is herein considered as a full species and redescribed. This species is characterized by its trapezoidal shell flank, elongated rostrum, tapering towards the tip, and external ornamentation composed of 18–53 radial ribs, the 3–4 posterior ones being the strongest and more widely spaced. Other three previously unknown species are illustrated but not formally named due to the lack of well-preserved articulated shells.

Authors: Del Prete Annachiara , Cabero Almenara Julio
Published: March 2020

El uso masivo de la tecnología, en la vida cotidiana y en la educación en particular, está teniendo siempre más influencias en la autopercepción, por parte de los/as docentes, de habilidades de uso de las TIC, así como en sus competencias digitales. El propósito del estudio ha sido analizar si se presentan diferencias de género en el uso pedagógico de la plataforma Moodle, encuestando una población de 640 docentes de una institución de educación superior técnico profesional de Chile. El estudio ha sido realizado a través del análisis estadístico basado en la prueba de significación de hipótesis nula y la variable género ha sido analizada de forma descontextualizada, sin tomar en consideración las interacciones que se puedan dar con otras variables. Entre los resultados principales se destaca la evidencia de que no se presentan diferencias significativas entre profesores y profesoras el uso didáctico de la plataforma Moodle, así como en la auto calificación del dominio de la misma.

The widespread use of technology in daily life, and particularly in education, increasingly influences both the self-perception of Information and Communication Technology skills and teachers’ digital competence. This study aims to analyze if there are gender differences in the pedagogical use of the Moodle platform, by conducting surveys among a population of 640 teachers from a technical professional higher education institution in Chile. The study of gender differences has been conducted through a statistical analysis based on a significance test of null hypothesis and the gender variable has been analyzed in a decontextualized manner, without taking into account the interactions that they could have with other variables. Among the primary results, evidence shows that there are no significant differences between female and male teachers with regard to the educational use of the Moodle platform as well as self-qualification with respect to proficiency on the platform

La presente investigación estudia los efectos que dos herramientas relacionadas con la autorregulación del aprendizaje tienen sobre el logro académico, las conexiones por día y el tiempo de dedicación al estudio. Un total de 260 estudiantes de formación profesional cuyo aprendizaje se desarrolla en línea fueron asignados de forma aleatoria a tres grupos: un grupo interactuaba en un aula virtual a cuya estructura se le había añadido una herramienta que muestra una barra de progreso con las tareas a realizar durante el curso (n=67); otro grupo interactuaba en un aula virtual al que se le añadía tanto la barra de progreso como una herramienta que estima el tiempo dedicación al estudio (n=75); y el grupo de control interactuaba sin ninguna herramienta añadida con respecto a las que se trabaja habitualmente en el aula virtual (n=118). Se realizaron análisis factoriales ANOVA y MANOVA. Los resultados muestran que no existe una diferencia significativa en el logro académico entre grupos, independientemente del tipo del aula virtual en la que interactúen. Sin embargo, existen diferencias significativas en el tiempo de dedicación y en las conexiones diarias entre grupos, dependiendo del tipo de aula virtual empleado. Como conclusión, los estudiantes del grupo en el que se incluye la barra de progreso mejoran su eficiencia, ya que obtienen un logro académico similar al resto de estudiantes en aproximadamente la mitad de tiempo.

The present research studies the effects that two tools related to self-regulated have on the academic achievement, the connections per day and the time of dedication to the study. A total of 260 vocational training e-learning students was randomly assigned to three groups: one group interacted in a virtual classroom in which a tool showing a progress bar with the tasks to be completed during the course was added (n=67); another group interacted in a virtual classroom in which both the progress bar and a tool that estimates the dedication time to the study was added (n=75); and the control group interacted without any extra tool added in the virtual classroom (n=118). ANOVA and MANOVA factor analysis were performed. The results show that there is no significant difference in academic achievement between groups, regardless of the type of the virtual classroom in which they interact. However, there are significant differences in the dedication time to the study and in the daily connections between groups, depending on the type of the virtual classroom was used. It is therefore concluded that the group in which the progress bar is included enhaces efficiency, because students obtain similar academic achievements in approximately half the time.
Percepción de impacto de Internet y medios sociales en la relación de los puertorriqueños con sus médicos
Authors: De la Cruz Cuebas Iván
Published: March 2020

Los objetivos de esta investigación fueron, primero, identificar las fuentes utilizadas por los ciudadanos en Puerto Rico en los medios sociales para búsqueda de información de salud. En segundo lugar, conocer como la búsqueda de temas de salud en Internet y Medios sociales ha afectado la relación con el médico. Se realizó una encuesta a través de la plataforma Google Forms con 250 participantes con preguntas precodificadas. En estas se cuestionó sobre las búsquedas de información de salud en redes sociales y en páginas web y cómo percibían que incidía en la relación con sus médicos. En general, aunque los medios sociales demuestran tener una creciente importancia en la búsqueda de informaciones sanitarias, las páginas web exhiben aún una relativa mayor confianza en el ciudadano. En todas las premisas aparece Internet y las páginas web como una fuente que afecta más la relación con los médicos en aspectos como la confianza percibida; la actitud del médico hacia la información y en las recomendaciones de referencia realizadas por los médicos. Los medios sociales resultan tener un efecto en dichos temas pero en un menor grado. En la mayoría de los casos las diferencias son pronunciadas y en otros la brecha es menor entre los efectos de la información de salud obtenida de Internet versus la de medios sociales.

Camino de perdición: de la posverdad y la poscensura a la oclocracia
Authors: Ródenas Gabri
Published: March 2020

El presente texto analiza las derivas del término «verdad» (real) y de qué modo ha influido en la configuración del espacio público, especialmente a través de su dimensión mediática. El objetivo es someter a debate y estudiar el origen y alcance de términos como posverdad, poscensura y la perversión de la democracia que supone la oclocracia. Para ello, se recurre a una metodología híbrida que combina el utillaje propio de la filosofía, la sociología y el análisis audiovisual y que tiene por finalidad aportar un poco de luz sobre el modo en que se combinan los diversos agentes del cambio, así como ofrecer algunas líneas de actuación que permitan minimizar los peligros potenciales de las nuevas formas de propagación de la información.
Las otras familias. Representaciones sobre parentalidades lesbianas y gays en dos series documentales argentinas
Authors: Silva Fernández Alejandro Alfredo Rafael
Published: March 2020

El trabajo tiene como objetivo indagar sobre las parentalidades lesbianas y gays que cobran visibilidad en producciones documentales argentinas estrenadas luego de la aprobación de la Ley de Matrimonio Igualitario. El corpus estará compuesto por los capítulos Familias diversas, Matrimonio Igualitario y Diversidad en el barrio de la serie documental Salida de Emergencia (2011) de Mathieu Orcel y La maternidad de Caleidoscopio: Diversos colores, los mismos derechos (2011) de María Victoria Glazmann. La metodología utilizada es cualitativa, retoma elementos de la semiótica del cine y los análisis contrastivo y textual. Se parte de la hipótesis de que la puesta en pantalla de la diversidad familiar toma parte en la construcción del género y se constituye como un espacio que habilita la circulación testimonial, a la vez que genera procesos de auto-representación y permite tensionar la hipotética inexistencia de otros modelos familiares, construida por la tradición audiovisual del país.
