Authors: Lizote Suzete Antonieta , Morais Marisa Luciana Schvabe de , Fontana Nathalie
Published: December 2021

O bem-estar subjetivo é um tema que busca compreender como o indivíduo avalia a satisfação em sua vida, a qual considera aspectos pessoais, vivências, valores e expectativas. Este estudo teve como objetivo identificar o bem-estar subjetivo e a autonomia no home-office dos professores universitários em tempos de pandemia da COVID-19. Trata-se de um estudo transversal com abordagem quantitativa. A amostra de 54 docentes de uma Universidade Comunitária do Sul do Brasil foi gerada pela aplicação da Escala de Bem-Estar Subjetivo de Albuquerque e Tróccoli (2004). Ela esteve dividida em aspectos positivos, negativos e satisfação com a vida e foi acrescentada uma dimensão denominada autonomia no home-office em tempos de pandemia da COVID-19. Os resultados apontaram que a maioria dos docentes, ou seja, 68,51%, apresentou um moderado bem-estar subjetivo, sendo os aspectos negativos superiores aos positivos com 16,66% e 14,81%, respectivamente. Por fim, se observou elevada autonomia no home-office com 66,67% das respostas. Conclui-se, portanto, que esses achados, de certa forma, são satisfatórios, pois, percebe-se que, mesmo tendo os afetos negativos sido mais presentes do que os aspectos positivos do bem-estar subjetivo, os docentes pesquisados estão comprometidos e buscando desempenhar suas atividades da melhor forma possível. Para as instituições que estão tendo que se adaptar em vários aspectos, isso é um fator determinante, pois são as pessoas os bens ativos mais importantes de uma organização.

Published: December 2021

Em março de 2020 foi declarado o estado de pandemia pela Organização Mundial de Saúde devido à transmissão do vírus SARS-CoV-2 em diversos países. Desde então começaram estudos para conhecer melhor as manifestações da COVID-19, que podem ser tanto assintomáticas, como também resultar em falência múltipla de órgãos. Sabe-se também que essa doença afeta o coração, com diversas manifestações nesse órgão. A miocardite viral é uma delas, a qual também foi relatada em infecções por outros vírus da família Coronaviridae, como o MERS. Como o novo coronavírus começou a infectar seres humanos apenas no fim de 2019, ainda não se sabe especificamente quais sequelas ele pode deixar a longo prazo, como lesões miocárdicas. Um achado que estimula a hipótese de que a COVID-19 tem relação com o coração é que pacientes infectados apresentam elevação de troponina, um biomarcador de lesão miocárdica. Nessa revisão, procuramos destacar, de acordo com a literatura obtida, as informações mais relevantes com enfoque no desenvolvimento e agravamento de miocardites agudas associadas à COVID-19.

Published: December 2021

COVID-19 pandemic has deeply affected medical practice, and conducts o minimize the overload of healthcare services were necessary. The objective of this study is to evaluate the impact of the pandemic in the practice of surgical procedures in Brazil. This is a descriptive study with data about hospitalizations for surgical procedures in Brazil from 2016 to 2020, collected from the Department of Informatics of Brazil’s Unified Health System (DATASUS). Primary analysis describes the variations in the number of elective, urgent and other types of surgical procedures performed during this period, by comparing the mean number of hospitalizations from 2016 to 2019 with the absolute number from 2020. Secondary analysis describe the variations in hospitalizations for surgical procedures during this period in each of Brazil’s geographical regions, and variations in different surgical procedure subgroups. There was a decrease of 14.88% [95% CI: 14,82-14,93] in hospitalizations for surgical procedures in 2020, when comparing to the mean between 2016-2019. Decrease rates were 34.82% [95% CI: 34,73-34,90] for elective procedures and 1.11% [95% CI: 1.07-1.13] for urgent procedures. Surgical procedure subgroups with highest decrease rates were endocrine gland surgery, breast surgery, oral-maxillofacial surgery and surgery of upper airways, face, head and neck. The overload of healthcare facilities demanded reductions in non-urgent activities to prevent services’ collapse. Further studies are needed to evaluate the social and clinical impact of such reductions and support the development of precise criteria defining which procedures should be prioritized.

SIN RESUMEN
Formation of the prospective engineer’s moral personality as a problem of modern technical education
Authors: Soboleva Elena Ivanovna
Published: December 2021

The paper substantiates the urgency of the problem of the technical specialists moral personality formation, harmoniously combining production, personal and public interests, and indicates the need to solve the problem of engineering personnels professional training organization, focused on the development of students (prospective engineers) morality. The author has revealed a role of moral values in the moral education of students of a technical university, which contributes to the formation of the moral personality of a future engineer as a person and a professional. The moral values of the Russian engineer, presented in the Codes of Ethics for the Engineer, are indicated. Attention is focused on the relationship between the concept of attitude and the concept of value, in the context of which (interconnection) the choice of moral values is substantiated, familiarization with which allows to educate the prospective engineer as a moral person. The specificity of moral values is revealed as conscious life meanings that determine the attitude of an engineer to technology, to colleagues and to society. Specific moral values that are identified determine a specific type of relationship between an engineer: good, humanism, duty, freedom, honesty (the attitude of an engineer to technology), kindness, mercy, reliability, conscience, fairness (the attitude of an engineer to colleagues), dignity, responsibility, benefit, truth, honor (the attitude of an engineer to society). The ways of introducing a student to moral values in the educational process of a technical university, contributing to the formation of the prospective engineers moral personality, are indicated: the use of the educational potential of educational disciplines; application in the educational process of methods that allow harmoniously to combine the acquisition of professional knowledge by students and their introduction to values; extracurricular work with students; corporate training program (interaction between the university and the enterprise).
Massive open online courses as a resource of mixed learning (on the example of humanities)
Authors: Tarakanova Elena Nikolaevna
Published: December 2021

The dominant direction in the development of online education, actively discussed by the pedagogical community, is training using massive open online courses (MOOCs). The key factor in the effectiveness of the implementation of MOOCs in the practice of educational organizations is primarily the availability of elite education. In modern conditions, which determine the priority of lifelong education (lifelong learning), it is particularly relevant to form schoolchildrens readiness for self-education, which can be facilitated by training on MOOC platforms. The broad discussion of MOOC implementation in educational practice is more concerned with university education, additional education and the system of advanced training. The use of MOOCs in school education in the publications of teachers-researchers is not considered fully enough and is mostly related to natural sciences. The paper analyzes the MOOC on the example of humanities and the features of the implementation of mixed learning models (inverted learning, autonomous group, individual trajectory) based on the use of online courses. This analysis suggests that there should be a need for more in-depth research in this area and the need to introduce elements of learning into school practice through massive open online courses. This will resolve the contradiction between the need for differentiation and individualization of training and the potential of existing unused massive open online courses.

Authors:   Institute of Public Finance, Zagreb, Croatia, Morić Milovanović Bojan , Wittine Zoran , Bubaš Zoran
Published: December 2021

The relationship between entrepreneurial orientation and business performance has been widely researched. However, in scientific literature there is still a need for further clarification when observing the before mentioned concepts, especially within the service SME context. Likewise, when observing this relationship it is necessary to look into the impact of entrepreneurial orientation on individual segments of business performance, i.e. on financial and non-financial constructs. Therefore, the aim of this paper is to explore the association of entrepreneurial orientation and small and medium business performance, while observing performance both as unidimensional and multidimensional concept. Furthermore, the paper tests whether moderation effect of external environment exists between entrepreneurial orientation and business performance among Croatian service SMEs.
The 2020 Mw 6.0 Jiashi Earthquake: Coinvolvement of Thin-Skinned Thrusting and Basement Shortening in Shaping the Keping-Tage Fold-and-Thrust Belt in Southwestern Tian Shan
Authors: He Yuqing , Wang Teng , Fang Lihua , Zhao Li
Published: December 2021

The Keping-tage fold-and-thrust belt in southwest Tian Shan is seismically active, yet the most well-recorded earthquakes occurred south of the mountain front. The lack of large earthquakes beneath the fold-and-thrust belt thus hinders our understanding of the orogenic process to the north. The 2020 Mw 6.0 Jiashi earthquake is an important event with surface deformation in the fold-and-thrust belt well illuminated by Interferometric Synthetic Aperture Radar, providing an opportunity to study the present-day kinematics of the thrust front through the analysis of satellite measurements of surface deformations. Here, we employ the surface deformation and relocated aftershocks to investigate the fault-slip distribution associated to this event. Further added by an analysis of Coulomb stress changes, we derive a fault model involving slips on a shallow, low-angle (∼10°) north-dipping thrust fault as well as on a left-lateral tear fault and a high-angle south-dipping reverse fault in mid-crust. Aftershocks at depth reflect the basement-involved shortening activated by a thin-skinned thrust faulting event. In addition, this earthquake uplifted the southernmost mountain front with relatively low topography, indicating the basin-ward propagation of the southwest Tian Shan.

Published: December 2021

We present an archive of scanned instrumental seismic bulletins pertaining to either a single station or a set of stations (network). This new service by the International Seismological Centre (ISC), called the ISC Electronic Archive of Station and Network Bulletins, is openly available at the ISC website. The archive is likely to be the most comprehensive to date, thanks to the collection from various sources done by the ISC in the past several decades. The search for scans of a seismic bulletin is based on the location of the town of the institution producing a bulletin. As such, the electronic archive is easy to use and is likely to facilitate the work of a wide community interested in studying past earthquakes and involved in preservation and digitization of analog recordings.

This study was carried out to determine some internal and external quality characteristics of 378 eggs collected between March and July from 42-week-old Guinea Hens (Numidae meleagris) raised by the public in Erzincan province, using mathematical formulas. Egg external quality features include shape index 73%, elongation 1.37, egg surface area 55.65 cm2, egg volume 40.39 cm3, shell thickness 0.28 mm, shell weight 3.19 g, number of pores-1 6686.05, number of pores-2 5156.10, number of pores- 3 5043.33 pieces, pore density-1 120.22 pore number/cm2, pore density-2 92.62 pore number/cm2, pore density-3 90.52 pore number/cm2; The yolk weight and white weight of the egg were determined as 6.02 g and 30.89 g, from the egg internal quality characteristics. As a result, in this study, yolk weight, shell weight and shell thickness values of egg internal and external quality characteristics calculated using mathematical formulas based on egg weight without spoiling the egg integrity were found to be lower than the values in some studies determined by measurement, while the white weight value was found to be higher.
Application of discounted cash flow model valuation: The case of Excide industries
Authors: Panigrahi Ashok , Vachhani Kushal , Sisodia Mohit
Published: December 2021

Theoretical and practical features of the widely used discounted cash flow (DCF) valuation approach are examined in depth in this paper. This research evaluates Exide Industries by using the DCF Valuation technique. It is widely accepted that the discounted cash flow approach is an effective tool for analyzing the situation of an organization even in the most complicated circumstances. The DCF approach, on the other hand, is prone to huge assumption bias, and even little modifications in an analysis' underlying assumptions may substantially affect the valuation findings. As a result, of the sensitivity analysis, we discovered bullish, base, and worst-case scenarios with target share prices of Rs. 253.25, Rs. 171.37, and Rs.133.25, respectively, by adjusting growth and WACC (Weighted-Average Cost of Capital) values.
Adaptive, but not by design: cash transfers in Latin America and the Caribbean before, during and after the COVID-19 Pandemic
Authors: Stampini Marco , Ibarrarán Pablo , Rivas Carolina , Robles Marcos
Published: December 2021

The socioeconomic crisis associated with the pandemic put cash transfer programs back at the top of the policy agenda. It showed that the Latin American and Caribbean regions income support systems were both fundamental and insufficient. In this paper, we present novel estimates of the coverage and beneficiary distribution of all non-contributory cash transfers both before and during the COVID-19 crisis. The former is useful to show the degree of preparedness of the region. The latter analyzes the magnitude of the policy response. While the literature presents estimates of coverage and leakage of conditional cash transfers and non-contributory pensions, our results are novel because they are the first to analyze coverage and leakage implemented in response to the COVID-19 crisis. In addition, we are the first to expand the focus to all non-contributory cash transfer programs, including those that are quasi-universal and/or unconditional. This is the most appropriate focus when the goal is to assess the ability to provide protection to larger population groups (including the vulnerable) and against transitory poverty caused by systemic shocks (such as pandemic or extreme weather events, which may become more and more frequent due to climate change). Using data from the Inter-American Development Bank “Harmonized Household Surveys from Latin America and the Caribbean”, which now provide a more comprehensive coverage of Caribbean countries, we show that before the pandemic non-contributory cash transfers covered 26% of the population of 17 countries with available data. Average coverage of the extreme poor, moderate poor and vulnerable population was 56%, 43% and 28% respectively. During the crisis, LAC governments implemented 111 new cash transfer interventions, increasing coverage to 34% of the population in 12 countries with available data. Average coverage increased among the moderate poor (50%) and vulnerable population (37%), while it remained unvaried amongst the extreme poor. Moving forward, the countries of the region are called to reform their social protection systems to make them more flexible, efficient, and sustainable, and including strategies that provide protection against shocks. In this way, resilient and responsive social protection systems can contribute to the fight against climate change and support a just transition towards net-zero emission societies. These efforts must also include measures to close the historical coverage gap amongst the poorest.
Caracterización espacio-temporal de la avifauna del cañón de Las Hermosas, Chaparral, Tolima, Colombia
Authors: Sánchez Guzmán Jessica Nathalia , Váquiro-García Juan Camilo , Losada-Prado Sergio
Published: December 2021

El Cañón de las Hermosas constituye una de las regiones menos exploradas del suroccidente del Tolima. Pese a albergar una gran diversidad de fauna, la información disponible sobre las aves de esta región y sus interacciones a nivel de comunidad es poca. Nuestro objetivo fue documentar la avifauna de la cuenca del río Amoyá y analizar su dinámica espacio-temporal durante el periodo 2013-2018. Utilizando las metodologías tradicionales de observación y redes de niebla registramos 252 especies, de las cuales siete son endémicas, 22 casi-endémicas, 17 migratorias y cinco están en peligro. A escala espacial, detectamos dos picos de mayor riqueza en las estaciones más altas y bajas, y cuatro ensamblajes de aves a lo largo del gradiente, en tanto que temporalmente observamos similitudes de 43,4 a 63,5 % en la composición de especies entre los años y una riqueza fluctuante a lo largo del tiempo. A pesar de que la cuenca del río Amoyá constituye un ecosistema altamente intervenido, las particularidades de su avifauna permiten postularlo como un área importante para la conservación.
Complex system properties in the spreading of COVID-19 pandemic
Authors: Quimbay Carlos
Published: December 2021

The objective of the present study was to show that the spread of the COVID-19 pandemic around the world shows complex system properties such as lognormal laws, temporal fluctuation scaling, and time correlation. First, the daily cumulative number of confirmed cases and deaths is distributed among countries as lognormals such that the time series exhibit a temporal fluctuation scaling. Second, the daily return time series of cases and deaths per day have associated Levy stable distributions and they have time correlation. The idea was to draw attention to the fact that the spread of the COVID-19 pandemic can be seen as a complex system, and, thus, contribute to the identification of the structural properties of this system, which is relevant as it is expected that future stochastic models describing the spread of the COVID-19 pandemic from a microscopic dynamics perspective should be able to explain the emergence of the structural properties identified here.
A coupled models Hydrodynamics - Multi headed Deep convolutional neural network for rapid forecasting large-scale flood inundation
Authors: HADJI Sofiane
Published: December 2021

Modeling large-scale flood inundation requires weeks of calculations using complex fluid software. The state-of-the-art in operational hydraulic modeling does not currently allow flood real-time forecasting fields. Data driven models have small computational costs and fast computation times and may be useful to overcome this problem. In this paper, we propose a new modeling approach based on a coupled of Hydrodynamics finite element model and Multi-headed Deep convolutional neural network (MH-CNN) with rain precipitations as input to forecast rapidly the water depth reached in large floodplain with few hours-ahead. For this purpose, one first builds a database containing different simulations of the physical model according to several rain precipitation scenarios (historic and synthetic). The multi-headed convolutional neural network is then trained using the constructed database to predict water depths. The pre-trained model is applied successfully to simulate the real July 2014 flood inundation in an 870 km2 area of La Nive watershed in the south west of France. Because rain precipitation forecast data is more accessible than discharge one, this approach offers great potential for real-time flood modelling for ungauged large-scale territories, which represent a large part of floodplain in the world.

Planeación e incertidumbre
Authors: Gonzalez Jorge Iván
Published: December 2021

Este artículo examina los problemas de la planeación en condiciones de incertidumbre. Siempre es necesario planear, pero el ejercicio se puede realizar demuy diversas maneras. Aquí se establece la diferencia entre planeación basada en la probabilidad de clase y planeación basada en la probabilidad de caso, y se muestra que así esta última prevalezca, es inadecuada y fracasa. Un ejemplo de sus limitaciones es el mal manejo de la crisis causada por la COVID-19. Se propone, entonces, volver la mirada hacia la probabilidad de clase, que es necesaria y suficiente para plantear las opciones de planeación de manera adecuada. Aunque este ejercicio es pertinente, la planeación requiere un paso adicional, el de la elección colectiva, y es entonces ineludible preguntarse por la dimensión ética. El tamaño del Estado se resuelve en la arena política, y en las sociedades democráticas debe ser compatible con el ejercicio de la libertad.
What Makes Learning Analytics Research Matter
Authors: Wise Alyssa F. , Knight Simon , Ochoa Xavier
Published: December 2021

The ongoing changes and challenges brought on by the COVID-19 pandemic have exacerbated long-standing inequities in education, leading many to question basic assumptions about how learning can best benefit all students. Thirst for data about learning is at an all-time high, sometimes without commensurate attention to ensuring principles this community has long valued: privacy, transparency, openness, accountability, and fairness. How we navigate this dynamic context is critical for the future of learning analytics. Thinking about the issue through the lens of JLA publications over the last eight years, we highlight the important contributions of “problem-centric” rather than “tool-centric” research. We also value attention (proximal or distal) to the eventual goal of closing the loop, connecting the results of our analyses back to improve the learning from which they were drawn. Finally, we recognize the power of cycles of maturation: using information generated about real-world uses and impacts of a learning analytics tool to guide new iterations of data, analysis, and intervention design. A critical element of context for such work is that the learning problems we identify and choose to work on are never blank slates; they embed societal structures, reflect the influence of past technologies; and have previous enablers, barriers and social mediation acting on them. In that context, we must ask the hard questions: What parts of existing systems is our work challenging? What parts is it reinforcing? Do these effects, intentional or not, align with our values and beliefs? In the end what makes learning analytics matter is our ability to contribute to progress on both immediate and long-standing challenges in learning, not only improving current systems, but also considering alternatives for what is and what could be. This requires including stakeholder voices in tackling important problems of learning with rigorous analytic approaches to promote equitable learning across contexts. This journal provides a central space for the discussion of such issues, acting as a venue for the whole community to share research, practice, data and tools across the learning analytics cycle in pursuit of these goals.

Authors: Prado Edemar O. , Bolsi Pedro C. , Sartori Hamiltom C. , Pinheiro José Renes
Published: December 2021

Este artigo apresenta um modelo analítico simples e acurado para cálculo de perdas em MOSFETs de potência. Uma análise comparativa entre o modelo proposto e modelos comumente utilizados na literatura é mostrado. O modelo proposto utiliza uma simplificação na modelagem das cargas das capacitâncias parasitas. Variações da temperatura de junção com a variação da frequência são consideradas. Resultados térmicos obtidos experimentalmente são usados para validar o modelo em frequências de até 300 kHz. Os resultados demonstram acurácia do modelo proposto usando dois part numbers de MOSFETs diferentes, com as tecnologias de superjunção e Silício convencional. Devido à acurácia e simplicidade de implementação, este modelo é recomendado para utilização em análises onde são verificados extensivos pontos de operação (tensão, frequência e potência), algorítimos genéticos e aplicações com banco de dados.

Published: December 2021

Este trabalho apresenta uma alternativa para a conexão de células ladder de capacitor chaveado com o objetivo de obter elevada taxa de conversão cc-cc. A modificação posposta consiste em dividir o capacitor de saída da célula de forma que ele seja o estágio de entrada de uma segunda célula ladder, ou seja, é realizada uma conexão série com integração de elementos. A modificação no capacitor de saída da célula permite a conexão com reduzido número de componentes. Essas vantagens tornam a estrutura adequada para conversores com alta taxa de conversão, tanto elevadores quanto abaixadores.

Background: Briquettes is more efficient than conventionally applied nutrients as it reduce the loss of nutrients by obtaining higher yield and decreased the expenditure cost of fertilizers. Indian soils are 49 per cent deficient in zinc which is characterized by widespread Zn deficiency in human beings. Methods: Three different zinc fortified briquettes viz., UB-DAP, UB-suphala and UB-KAB were tested in field experiments during kharif season of 2016-19 to compare and calculate variations in yield, yield attributing characters and nutrients uptake by rice (Oryza sativa L.). Result: The results showed that treatment UB-KAB fortified with 10 kg ZnSO4.7H2O ha-1 (T8) registered higher growth, yield parameters and Zn concentration in grain indicating zinc-sulfate-heptahydrate (ZSHH) offers vital solution to curtail Zn malnutrition. Further, UB-KAB fortified through ZSHH (T8) significantly enhanced the grain (55.2 q ha-1) and straw (63.6 q ha-1) yield of rice over RDF and absolute control. Application of UB-KAB fortified with 10 kg ZnSO4.7H2O ha-1 (T8) significantly increased nutrient uptake of N (97.2 kg ha-1), P (20.2 kg ha-1), K (95.5 kg ha-1), Zn (262.4 g ha-1) and S (53.9 kg ha-1) over fertilizer control (75% RDF) and absolute control. The applications of KAB fortified with zinc sulphate assume great significance in improving rice productivity.

El crecimiento económico y demográfico de los países han incrementado la tasa de generación de residuos sólidos, y ha creado una nueva amenaza para la sostenibilidad. El objetivo principal de este estudio fue estimar el potencial de gas metano en el relleno sanitario de residuos sólidos de la mancomunidad Patate-Pelileo, Tungurahua, Ecuador mediante el modelo LandGEM, modificado a las condiciones de Ecuador. Para ello se utilizó información desde inicio del relleno, vida útil, clima, cantidad de residuos, composición de los residuos que fueron obtenidos de bases de datos y reportes estadísticos. Como resultado, se observa que la cantidad de metano calculada para los primeros 20 años fue de 33.070.236,19 m3, una media anual de 1.653.511,81 m3, y el valor máximo se alcanza en el año 2032 (1.985.270.108 m3). La investigación permite concluir que los modelos de estimación se pueden utilizar para la planificación de la producción de energía y otros usos del gas de relleno sanitario, pero tienen gran dependencia de la calidad de los datos disponibles, y de la selección de los coeficientes correctos. Además, están fuertemente influenciada por las cantidades de residuos generadas.
Shaykh Abdullah Fahim's Views on Salawat in a Psychological Perspective

Published: December 2021

Abstract: Psycho-religion is classified as the highest spiritual psychotherapy in the field of psychology. This is because the field involves religion that works to increase confidence thus speeding up the healing process. One of the therapies that fall into this category is the practice of reciting Salawat. This practice is common in traditional institutions of learning institutions in the Malay world. In some places, this practice becomes part of the curriculum of study. Some recite it as remembrance, and some recite it in the form of melodic performances such as qasidah, hadrah and so on. This study, however, is limited to the views of prominent educators in Malaya, Shaykh Abdullah Fahim (1869 - 1961) to practice reading the Salawat. The main objective of this study is to look at Shaykh Abdullah Fahim's thoughts on Salawat from a psychological perspective. This study uses a fully qualitative method. For data collection purposes, an archival approach was used. The conclusion of the study was made by using an inductive approach that is by summarizing the findings in general. The study found that the practice of Salawat from the point of view of Shaykh Abdullah Fahim has potential development benefits in terms of emotions, behaviour, and motivation.Keywords: Shaykh Abdullah Fahim; Salawat; psycho-religion; psychologyAbstrak: Psikoreligius tergolong psikoterapi spiritual tertinggi dalam bidang psikologi psikoterapi.

Análise estilística e economia da montagem na Cinédia (1940-1946)
Authors: Adamatti Margarida Maria , Uchôa Fábio Raddi
Published: December 2021

O artigo propõe a análise estilística de sete filmes produzidos pela Cinédia na década de 1940 tendo em vista a economia da montagem da empresa e seu modo de produção. Face à lacuna sobre as continuidades estilísticas da companhia de Adhemar Gonzaga, o estudo sobre o estilo coletivo enfatiza as recorrências formais de quatro procedimentos técnicos: campocontracampo, plano longo, enquadramento móvel e encenação em profundidade. Observando se o gênero, o orçamento e as condições de filmagem podem ter se integrado à estrutura interna das obras, a proposta pretende avaliar como tais procedimentos relacionam-se ao ritmo da montagem e à configuração espacial das obras.
Bayesian Estimation of The Ex-Gaussian Distribution

Published: December 2021

Fitting of the exponential modified Gaussian distribution to model reaction times and drawing conclusions from its estimated parameter values is one of the most popular method used in psychology. This paper aims to develop a Bayesian approach to estimate the parameters of the ex-Gaussian distribution. Since the chosen priors yield to posterior densities that are not of known form and that they are not always log-concave, we suggest to use the adaptive rejection Metropolis sampling method. Applications on simulated data and on real data are provided to compare this method to the standard maximum likelihood estimation method as well as the quantile maximum likelihood estimation. Results shows the effectiveness of the proposed Bayesian method by computing the root mean square error of the estimated parameters using the three methods.
La evaluación y la matematización del sujeto. El tú puedes en el discurso pedagógico
Authors: Hours Germán
Published: December 2021

La formación ciudadana a la cual responde la educación, como bien señaló Michel Foucault (1985), requiere de generar sujetos dóciles y productivos que internalicen y se apropien de los requerimientos de la sociedad capitalista, naturalizando los mandatos sociales, como un producto lógico, pero también correspondiente a un orden natural, para garantizar el buen funcionamiento del sistema de vida. En este contexto la evaluación ha jugado un papel extraordinario. Sirviendo como herramienta de estandarización y clasificación institucional ha tenido la función de legitimar ciertas ideas que son instituyentes del sistema capitalista. Siguiendo estas ideas, en este artículo, se presentan algunas perspectivas teóricas que permitan profundizar en estas cuestiones, estableciendo un corrimiento del discurso tradicional, para posibilitar una mirada política, crítica y amplia sobre el tema.

Following the 2013 curriculum, the mathematics learning process requires critical and creative skills that can help students solve a problem on math problems. Students who maximize critical thinking can conclude the information obtained, know how to use the information in math story problems, and find sources of supporting communication in solving a problem. In addition, students must have creative thinking skills that find new ideas or ideas from math story problems. This study discussess the importance of critical and creative thinking skills in elementary school students in solving math story problems. The method used in this research is the library research method with a qualitative approach. Critical thinking skills are an active process that continuously and thoroughly contains the contents of one's thoughts about something in-depth to decide what to believe or do. At the same time, creative thinking skills are the process of bringing up or bringing up a new idea based on a combination of previous experience. New ideas emerge from old ideas combined in new ways. The learning model that supports students in solving story problems is Problem Solving.
