Roman Hydraulic Engineering: The Pont du Gard Aqueduct and Nemausus (Nîmes) Castellum
Authors: Ortloff Charles R.
Published: December 2020

The water distribution castellum at the terminal end of the Pont du Gard aqueduct serving the Roman city of Nemausus in southern France is analyzed for its water engineering design and operation. By the use of modern hydraulic engineering analysis methods applied to analyze the castellum, new aspects of Roman water engineering technology are discovered not previously reported in the archaeological literature. Analysis of the castellum’s 10 basin wall flow distribution pipelines reveals that when a Roman version of modern critical flow theory is utilized in their design, the 10 pipelines optimally transfer water to city precincts at the maximum flow rate possible with a total flow rate closely approximating the input flow rate from the aqueduct. The castellum’s three drainage floor ports serve as additional fine-tuning to precisely match the input aqueduct flow rate to the optimized 10 pipeline output flow rate. The castellum’s many hydraulic engineering features provide a combination of advanced water engineering technology to optimize the performance of the water distribution system while at the same time enhancing the castellum’s aesthetic water display features typical of Roman values. While extensive descriptive archaeological literature exists on Roman achievements related to their water systems both in Rome and its provinces, what is missing is the preliminary engineering knowledge base that underlies many of their water system’s designs. The present paper is designed to provide this missing link by utilizing modern hydraulic engineering methodologies to uncover the basis of Roman civil engineering practice—albeit in Roman formats yet to be discovered.

High living standards and a comfortable modern way of life are related to an increased usage of various plastic products, yielding eventually the generation of an increased amount of plastic debris in the environment. A special concern is on microplastics (MPs), recently classified as contaminants of emerging concern (CECs). This review focuses on MPs’ adverse effects on the environment based on their bioactivity. Hence, the main topic covered is MPs’ ecotoxicity on various aquatic (micro)organisms such as bacteria, algae, daphnids, and fish. The cumulative toxic effects caused by MPs and adsorbed organic/inorganic pollutants are presented and critically discussed. Since MPs’ bioactivity, including ecotoxicity, is strongly influenced by their properties (e.g., types, size, shapes), the most common classification of MPs types present in freshwater are provided, along with their main characteristics. The review includes also the sources of MPs discharge in the environment and the currently available characterization methods for monitoring MPs, including identification and quantification, to obtain a broader insight into the complex problem caused by the presence of MPs in the environment.

Published: December 2020

Electrosorption is a new emerging technology for micro-polluted water treatment. To gain a more accurate understanding of the mass and charge transfer process of electrosorption, the electrosorption performance of activated carbon fiber (ACF) electrodes with various concentrations was studied. In this paper, quasi-first-order and quasi-second-order dynamic equations, and an intra-particle diffusion equation were used to describe the electrosorption behaviors. It is believed that the electrosorption process is dominated by physical adsorption for ACF material, and the most important rate control steps in this process are intra-diffusion and electromigration steps. Based on the experimental results and modified Donnan model theory, a considerable electrosorption dynamic model which considered the influence of physical adsorption and the intra-diffusion resistance was proposed. This model quantitatively described the salt adsorption and charge storage in the ACF electrode and can fit the experimental data well.

Published: December 2020

Sugar beet by-products are a lignocellulosic waste generated from sugar beet industry during the sugar production process and stand out for their high carbon content. Moreover, cow manure (CM) is hugely produced in rural areas and livestock industry, which requires proper disposal. Anaerobic digestion of such organic wastes has shown to be a suitable technology for these wastes valorization and bioenergy production. In this context, the biomethane production from the anaerobic co-digestion of exhausted sugar beet pulp (ESBP) and CM was investigated in this study. Four mixtures (0:100, 50:50, 75:25, and 90:10) of cow manure and sugar beet by-products were evaluated for methane generation by thermophilic batch anaerobic co-digestion assays. The results showed the highest methane production was observed in mixtures with 75% of CM (159.5 mL CH4/g VolatileSolids added). Nevertheless, the hydrolysis was inhibited by volatile fatty acids accumulation in the 0:100 mixture, which refers to the assay without CM addition. The modified Gompertz model was used to fit the experimental results of methane productions and the results of the modeling show a good fit between the estimated and the observed data.
A Modelling Framework for the Conceptual Design of Low-Emission Eco-Industrial Parks in the Circular Economy: A Case for Algae-Centered Business Consortia

Published: December 2020

This article describes a unique industrial symbiosis employing an algae cultivation unit (ACU) at the core of a novel eco-industrial park (EIP) integrating fossil-fuel fired power generation, carbon capture, biofuel production, aquaculture, and wastewater treatment. A new modelling framework capable of designing and evaluating materials and energy exchanges within an industrial eco-system is introduced. In this scalable model, an algorithm was developed to balance the material and energy exchanges and determine the optimal inputs and outputs based on the industrial symbiosis objectives and participating industries. Optimizing the functionality of the ACU not only achieved a substantial emission reduction, but also boosted aquaculture, biofuel, and other chemical productions. In a power-boosting scenario (PBS), by matching a 660 MW fossil fuel-fired power plant with an equivalent solar field in the presence of ACU, fish-producing aquaculture and biofuel industries, the net CO2 emissions were cut by 60% with the added benefit of producing 39 m3 biodiesel, 6.7 m3 bioethanol, 0.14 m3 methanol, and 19.55 tons of fish products annually. Significantly, this article shows the potential of this new flexible modelling framework for integrated materials and energy flow analysis. This integration is an important pathway for evaluating energy technology transitions towards future low-emission production systems, as required for a circular economy.

Published: December 2020

The major lockdown due to the COVID-19 pandemic has affected the socio-economic development of the world. On the other hand, there are also reports of reduced pollution levels. In this study, an indicative analysis is adopted to understand the effect of lockdown on the changes in the water quality parameters for Lake Hussain Sagar using two remote sensing techniques: (i) spectral reflectance (SR) and (ii) chromaticity analysis (Forel-Ule color Index (FUI) and Excitation Purity). The empirical relationships from earlier studies imply that (i) increase in SR values (band B2) indicates a reduction in Chlorophyll-a (Chl-a) and Colored Dissolved Organic Matter (CDOM) concentrations, and (ii) increase in FUI indicates an increase in Total Suspended Solids (TSS). The Landsat 8 OLI satellite images are adopted for comparison between (i) January to May of year 2020: the effect of lockdown on water quality, and (ii) March and April for years 2015 to 2020: historical variations in water quality. The results show notable changes in SR values and FUI due to lockdown compared to before lockdown and after unlock suggesting a significant reduction in lake water pollution. In addition, the historical variations within April suggest that the pollution levels are least in the year 2020.

Sunflower seeds are rich in oil and protein. In a two-year field experiment in Hetao district, Inner Mongolia, we evaluated the effects of irrigation and N fertilizer on protein and amino acid content of sunflower seeds (Kang Di T562 variety). Irrigation water and N fertilizer were applied at the bud to blossom stage and at three levels: water at 90, 45, and 0 mm; N fertilizer at 104, 52, and 0 kg hm−2. There were nine treatments with three replicates for a total of 27 plots arranged randomly in blocks. In combination with environmental conditions, water, nitrogen, and the interaction between the two had significant effects on total protein, total amino acids, total ammonia, and key amino acids: glutamic acid, arginine, aspartic acid, glycine, and valine. Application of N fertilizer at the bud stage promoted protein synthesis in seed kernels at the ripening stage. We found a significant positive correlation between N fertilizer and the five main amino acids. With increasing irrigation, total amino acid content and the content of each of the key amino acids individually first increased but then decreased. Overall, a water deficit improved protein content in seed kernels.

Published: December 2020

River ecosystems are one of the dynamic components of the terrestrial carbon cycle that provide a crucial function in ecosystem processes and high value to ecosystem services. A large amount of carbon is transported from terrestrial to the ocean through river flows. In order to evaluate the contribution of Sile River ecosystem to the global carbon stock, the river ecosystem Organic Carbon (OC) stock was quantified for sediments and dominant submerged aquatic macrophytes (SAMs) during the two sampling periods at three different stations along the Sile River (North Eastern Italy). The total mean ecosystem OC stock was 95.2 ± 13.8 Mg C ha−1 while those of SAMs ranged from 7.0 to 10.9 Mg C ha−1 which accounted for approx. 10% of the total OC stock. The total aboveground biomass retains approx. 90% of the SAM carbon stock, with a mean of 8.9 ± 1.6 Mg C ha−1. The mean sediment OC stock was 86.6 ± 14.5 Mg C ha−1 with low seasonal variations among the sites. Indeed, various environmental parameters and hydrodynamics appear to affect the accumulation of OC within the river ecosystem. The results highlight the role that freshwater river ecosystems play in the global carbon cycle, which consequently provide a baseline for future river ecosystem monitoring programs. Furthermore, future studies with additional sites and seasonal surveys of the river will enhance our understanding of the effects of global climate change on the river ecosystem and improve the ecosystem services.
R-effect of decomposition of duplicate systems into equiprobable functional nodes
Authors:   Institute of Mathematical Machines and Systems Problems of the Ukraine National Academy of Science, Fedukhin O.V.
Published: December 2020

The work is devoted to the reliability of non-recoverable two-channel automation systems and computer equipment. As alternative options, a system with block duplication (SBD) and a system with a quasi-bridge structure (QBS) are considered. SBD in general is a two-channel system consisting of a series connection of duplicated nodes of different reliability. In case of failure of one of the functional subunits (FSU) of the duplicated node using the control and reconfiguration (SCR) scheme, it is masked, withdrawn from the computational process, and reconfigured the system structure in the “Non Stop” operating mode. A QBS system also represents a two-channel structure, but consisting of a serial connection of duplicated nodes of equal reliability, while the technical element intensity (redundancy level) and the functionality of this system are identical to SPD. The QBS system is also a fail-safe system that provides the “Non Stop” mode of operation. The probabilistic-physical calculation method (WF-method) is used as a tool for studying the reliability of systems, which is based on the diffusion distribution of mean-time-to-failure (DN-distribution), specially formalized for assessing the reliability of electronic, electrical and electromechanical elements and systems. While maintaining the redundancy level of the considered two-channel redundant systems, decomposing the channels into equally reliable duplicated nodes leads to the R-effect – an increase in the likelihood of system uptime with an increase in the number of nodes. The presence of the R-effect was established by other methods of calculation and by statistical modeling for both non-restored and restored systems.

The nature of weakly structured systems is specified by using of expert estimates, the inherent uncertainty of which belongs to the fuzzy class. Unlike stochastic uncertainty, fuzziness complicates or even eliminates the use of statistical methods and models, but can be used to make subject-oriented decisions based on approximate reasoning of a person. The formalization of intellectual operations simulating fuzzy human statements about the state and behavior of weakly structured systems and/or complex phenomena today forms an independent direction of scientific and applied researches, one of which is fuzzy modeling of time (or dynamic) series. This direction includes a task complex, the methodology of which is based on the theory of fuzzy sets, fuzzy logic and fuzzy models (or fuzzy inference systems). The initial procedure for fuzzy modeling of time series is fuzzification of historical data obtained by observing on the basis of “soft measurements” of the behavior of a dynamic system for a certain period of time. The paper proposes a new rule of fuzzification of such data, which is tested on the indicators of the Dow Jones Industrial Average, established by the results of daily trading on the US stock exchange by the usual arithmetic averaging of component indicators. The fuzzification procedure proposed in the given paper is implemented through a fuzzy inference system, which ensures that the membership functions of the corresponding fuzzy subsets of the discrete universe are found, covering the entire set of indicators of the Dow Jones index for more than a year.

The concept of mobile and home telemedicine for screening and early diagnostics of cardiovascular dis-eases is being expanded due to the emergence of mobile diagnostic devices and smartphones. In the course of such telemedicine consultations, the doctor must be sure that the digital electrocardiogram (ECG) be-longs to the patient who was registered. Both multi-channel and single-channel ECG-recording devices are available on the telemedicine consulting market now. Single-channel electrocardiographs are more eco-nomic feasible for home use. Previously, the authors have developed and experimentally tested the algo-rithms for patient authentication by his/her multi-channel ECG. These algorithms are based on the analysis of the shape of QRS complex in three-dimensional phase space of coordinates. Therefore, it is reasonable to adapt these algorithms to single-channel ECG. In case of multi-channel ECG, we can construct a three-dimensional phase space of coordinates by obtaining all the necessary data from the ECG leads. In a case of the single-channel ECG it is necessary to create two additional signals artificially and then it will be possible to form a synthetic phase space. In general, the question of the validity of biometric person au-thentication algorithms by his/her ECG with a limited number of channels is discussed in this paper. Be-sides the algorithms for solving the problem of authentication, the comparison of sensitivity and specificity indicators, calculated on the results of experiments for multi-channel and single-channel ECG, are also given in this paper. The results of experiments with multi-channel and single-channel ECG of a larger number of patients are given in comparison to the previous experiments. The results of the experiments for the case of recording ECG signals by different devices are given as well.

Published: December 2020

Coligranulomatosis, which induces hepatic granulomas, and Marek's disease, one of the important neoplastic diseases in poultry, rarely causes outbreaks in turkeys. In this study, etiological diagnoses were performed in the light of post-mortem, histopathological, microbiological, and immunohistochemistry studies of turkeys that died in a commercial establishment in the region of Konya. In the post-mortem examination, many grey-white foci with a diameter of 3-10 mm, which sometimes spread from serosa to the parenchyma, were found in the liver. Mucous exudate and hyperemia were detected in all segments of the intestine. For microscopic examination, all tissues were stained with Haematoxylin-Eosin and some selected liver tissues with Periodic Acid-Schiff, Ziehl-Neelsen, and Giemsa. Typical structures of pyogranulomas with an eosinophilic necrotic core in the liver were identified. Tumor foci formed by pleomorphic histiocyte and lymphoid cells were also observed in the liver, spleen, and intestines (jejunum and cecum). In the selected liver and intestinal sections, a positive reaction was obtained in tumor cells in immunohistochemical staining with the primary antibody specific for Marek's disease virus. In addition, Escherichia coli isolation was performed microbiologically in swaps and samples taken from lesioned areas of the liver. As a result of the examinations, other etiological agents that may cause hepatic granulomas in the turkeys were excluded, and coligranulomatosis and Marek's disease were diagnosed simultaneously in this turkey flock. It was concluded that in cases in which these two diseases are observed simultaneously, the diseases might interact with each other, and casualties may increase.

Zumbis nunca morrem: entrevista com Mark Deuze
Authors: Ribeiro Alexsandro Teixeira , Ferro Jeferson
Published: December 2020

No contexto da pandemia de coronavírus, o lar se tornou o "supra-local" de nossa existência, o lugar para onde convergem os diferentes tipos de interação que governam nossas vidas, antes fisicamente separadas (FUCHS, 2020). Deuze (2020) acrescenta outra convergência a esse cenário, a de dois sistemas de mídia, o tradicional (jornalismo mainstream) e o novo (mídias sociais). Em sua recém-publicada revisão das teorias fundamentais da comunicação e de sua importância para a compreensão do momento em que vivemos, ele destaca que o poder da desinformação é superestimado por instituições como a ONU, uma atitude que “... corresponde a uma visão inspirada no conceito de sociedade de massa que vê o público como uma massa de pessoas atomizadas, incapazes de dar sentido à realidade fora das mensagens a que são expostas na mídia” (2020, p. 9).

A abordagem pode parecer estranha, sobretudo para quem rememora o afamado conceito de zumbi midiático de Deuze (2013), que designa indivíduos que vivem não com a mídia, mas na mídia (2012), em um ambiente em que se apagaram as linhas de fronteira entre o off e o on line. Adaptados às demandas pela sobrevivência do século XXI, os zumbis perdem-se na coletividade. “Nós somos zumbis no sentido em que sucumbimos acéfalos ao chamado de nossos aparelhos; somos zumbis porque usamos as mídias de modos que apagam nossas distinções como indivíduos” (DEUZE, 2013, p.114).

Professor da Universidade de Amsterdã, Mark Deuze, autor de “Media Life” (2012) e “Beyond Journalism” (2020) acredita que atualmente o estudo da mídia e das práticas de comunicação é fundamental para a compreensão de nossos papéis no mundo. Nesta entrevista, que nos concedeu por e-mail entre julho e agosto de 2020, o questionamos sobre alguns dos principais temas que têm estado sob a sua investigação nas últimas duas décadas, em especial a reinvenção do jornalismo e a mudança do papel da mídia em nossas vidas.

Published: December 2020

Plant macrofossils from the upper middle Miocene Konan Tuffaceous Sandstone and Mudstone Member of the Bifuka Formation, known as the Konan flora, northwest of Shibetsu City, Hokkaido, Japan, were taxonomically revised. A total of 31 taxa were recognized, which were assigned to 14 families and 19 genera, including a new fossil species, Salix palaeofutura sp. nov. The Konan flora includes three taxa of evergreen conifers, one perennial monocot herb and 27 deciduous dicots. The most abundant and common species were Fagus palaeojaponica, Acer subcarpinifolium, Acer protojaponicum, Picea sp. A and Cercidiphyllum crenatum, in addition to a number of species of the Betulaceae and Salicaceae. From the absence of evergreen angiosperms as well as the common occurrence of Fagus palaeojaponica, Picea, Acer and Betulaceae species, this flora was comparable to that seen in the modern Mixed Northern Hardwood Forest of East Asia, which is distributed in northernmost Honshu and extends toward lowland Hokkaido. On the basis of floral features, mode of occurrence, and the lithology of plant-bearing beds, the Konan flora was deemed to represent mountain to riverside vegetation with humid and cool temperate climatic conditions. In contrast to the early to late Miocene floras in Japan, the Konan flora belongs to the late Miocene–Pliocene Mitoku-type flora, with a few relict species from the early Miocene. The Konan flora represents one of the earliest occurrences of this type of flora, suggesting that floral modernization was initiated much earlier in areas with humid and cool temperate climate than previously thought.

Para tanto, desenvolveu-se uma pesquisa de abordagem qualitativa e uma pesquisa-ação do tipo exploratória. Participaram deste estudo alunos do 9º ano de uma escola municipal do interior da Paraíba. O estudo revelou que esse aplicativo é eficiente na realização de avaliações formativas por contribuir para a otimização do tempo dos professores na correção das avaliações, por viabilizar, de forma imediata, um feedback individual e coletivo dos envolvidos e, ainda, por diminuir gastos com materiais didáticos pelo professor. Este estudo se mostra significativo, ao destacar uma diversificação do trabalho docente através de uma ferramenta digital disponível na web gratuitamente.

O ensino do português no sistema universitário francês
Authors: Boganika Luciane , Bernardon de Oliveira Katia
Published: December 2020

O presente artigo pretende apresentar o panorama no qual se insere o ensino de português língua estrangeira (PLE) na França. Mais especificamente, falaremos das possíveis formações ligadas ao português no contexto universitário. Para isso, apresentaremos as diferentes graduações em português, bem como seu ensino em centros de línguas ou ainda a obtenção de um diploma universitário (diferente da graduação). Num segundo momento, ilustramos essas formações através de estatísticas obtidas através do site da Embaixada do Brasil na França em relação à presença do português nas universidades. Observamos assim qual formação é a mais recorrente, e por conseguinte, apresenta mais público, e quais instituições dispõem de uma formação dita completa: graduação/mestrado/doutorado. Como conclusão, podemos ver que, apesar do português ter sido reconhecido como língua minoritária, ocupando ainda hoje pouco espaço em território francês, há formações distribuídas em diferentes regiões francesas; porém, tal presença não é suficiente para assegurar condições satisfatórias para o ensino da língua portuguesa. Sendo assim, esperamos apresentar tal realidade, com o intuito de alertar atores da área, pois, ao longo dos anos, muitos departamentos foram fechados, houve congelação de cargos de professores efetivos, e as formações ditas completas são cada vez mais escassas.
LANGUAGE SITUATION AND LANGUAGE POLICY IN THE CANADIAN PROVINCE OF QUEBEC
Authors: Kozhemyakina V.A.
Published: December 2020

The article analyzes the language situation and language policy in the Canadian province of Quebec. The Federal and provincial laws on the language adopted in the second half of the XX century are analyzed and the situation in which the French language was in the province of Quebec is indicated. The sixties of the last century in Quebec is called the "quiet revolution", it was a period of profound social and political changes. The quiet revolution was peaceful, evolutionary, but it involved the entire population of the province. The "revolution" was accompanied by a change in the ethnic imbalance in the society, in which the both political and economic powers were in the hands of the English-speaking minority. Another important aspect was the modernization and secularization of the Franco-Canadian community and the rise of its standard of living up to the average level of Anglo-Canadians one. French-speaking Canadians who were at a lower stage of economic development, was on the edge of loosing their native language, which caused a strong rise of the nationalist movement in Quebec, which was directed by provincial authorities to rescue the Quebec version of the French language and improving socio-economic situation of the French speaking community.
MULTIDISCIPLINARY APPROACH OF TEACHING FOREIGN LANGUAGE IN MILITARY ACADEMY
Authors: Kuchinskaya E.A.
Published: December 2020

The article is devoted to the practice of introducing subject-language integrated training (CLIL) in a military university, which receives insufficient attention in modern teaching methods. The article presents the scientific directions of the organization and the basic principles of bilingual education in special disciplines and a foreign language in technical universities of the country. 4 stages of studying a foreign language at a military university using CLIL technology are described. A new approach to the study of a foreign language is presented as interdisciplinary coordination of a foreign language, humanitarian (history, Russian, translation), natural sciences (physics and mathematics) and military (military-technical) disciplines. All of these disciplines are a tool in mastering the professional knowledge of future military specialists and increasing their professional competence. Intersubject integration at the moment is characterized by a new attitude to the subject of teaching a foreign language - obtaining professional knowledge while simultaneously mastering knowledge, skills in a foreign language and other special disciplines according to the Federal State Educational Standard. The purpose of the study is to identify the links between the humanities and science disciplines for the application of an integrated approach in practical lessons. The study of technologies and approaches to interdisciplinary training in a military university and their use in the educational process is the relevance of the study. The analysis of scientific and theoretical materials of foreign and Russian authors confirms the use of subject-integrated training at a military university. Based on the results of an empirical study, a number of practical recommendations were developed for teachers of military universities. The article provides the organization of an integrated practical lesson in a foreign language with third-year cadets. Tasks for the integration of a foreign language and knowledge of cadets in the field of mathematics and physics have been developed. Methodological recommendations on the organization of subject-based integrated learning in foreign language classes are given. The article emphasizes that interdisciplinary interaction is a complex organizational task and a unified model of subject-integrated education in a military university does not yet exist, and its actualization depends on the capabilities of a particular university.

Published: December 2020

The article is devoted to the consideration of some issues of intercultural language education related to the formation of strategies for working with cultural information, personal mastery of ways to overcome intercultural difficulties by integrating the ideas of existing approaches of a general didactic and intercultural orientation, as well as taking into account global information challenges. The obligatory component of intercultural interaction is intercultural difficulties, which create certain obstacles to achieving intercultural dialogue. The article describes the types of intercultural difficulties and their didactic functions (cognitive, informative, sociocultural and meditative). The strategies of working with cultural information, considered as a basic component of the information and cognitive activities of subjects of intercultural interaction to overcome intercultural difficulties, are considered. These strategies ensure the creation of a platform for intercultural dialogue during the consideration of problems of an intercultural nature and are specified in the methods and operations of informational and cognitive activities. A review of linguodidactic practices aimed at the formation of the considered strategies.

Authors: Ballesteros Ibarra María Lorena , Mercado Varela Martín Alonso , García Vázquez Nancy Janett , Glasserman Morales Leonardo David
Published: December 2020

En los últimos años, los Cursos en Línea, Masivos y Abiertos (MOOC) se han convertido en importantes escenarios para el aprendizaje profesional de los maestros. En este contexto, se tuvo el objetivo de comprender las experiencias de aprendizaje profesional que un grupo de docentes de educación primaria en México vivenció en el conjunto de MOOC denominados “Colección de Aprendizajes Clave”. Se utilizó el método de investigación cualitativo y como instrumento se aplicó una entrevista semiestructurada a 17 profesores en servicio. Los hallazgos sobre las experiencias de aprendizaje de los profesores se categorizaron en: (1) interacción con la propuesta didáctica de los MOOC; y (2) finalización o abandono de los MOOC. Dentro de la primera categoría, se detallan los elementos didáctico-pedagógicos que caracterizaron la construcción de los aprendizajes de los maestros, como lo son: actividades, interacción entre los participantes, recursos para aprender y esquemas de evaluación. En la segunda categoría, se resaltan las motivaciones y habilidades que favorecieron que algunos profesores finalizaran los MOOC, y cómo la ausencia de algunas de ellas influyó en el abandono de los cursos por parte de otros maestros; el compromiso con la labor docente fue una motivación identificada, y dentro de las habilidades se resaltaron las digitales, las de autorregulación y las de gestión del tiempo. Estos resultados son de utilidad para favorecer la construcción de ambientes en línea, masivos y abiertos que fomenten el aprendizaje profesional de los maestros.
Digital stories

Published: December 2020

Feedback is an important topic in education, and particularly for language development. This article intends to present some results of a research study aimed at investigating students’ perception concerning the feedback received during the script development in an L2 for the production of a digital story as well as the use made of the received feedback. Participants were students from Letras Inglês course. During the course, participants were required to develop a digital story, and feedback was provided for the script development phase. After the production of their digital stories, they were asked to answer a questionnaire and also participate in an interview, both focusing on their perceptions concerning the feedback received. A comparison between the digital story (the video) and the script with teacher’s feedback was also made to better understand the use participants made of the feedback. Results showed that participants acknowledged the relevance of feedback by emphasizing some aspects that were improved, such as the organization of ideas, punctuation problems, and also the development of an awareness for written productions. Concerning the use of the feedback received, results showed that the production of the digital story (the video) was an encouragement for the incorporation of the feedback received.

La aplicación de las ontologías en el aprendizaje adaptativo contribuyen implementar alternativas tecno – pedagógicas con un profundo fundamento computacional. Para proyectar investigaciones de innovaciones educativas es importante determinar cuáles son los principales pares de variables dependiente (VD) y independiente (VI) que se han estudiado en el último lustro (2015-2019). En esta década, diversos estudios teóricos están presentes en Scopus hasta el 2018 pero no logran identificar por cada publicación la relación VD-VI. Ello motivó a realizar un mapeo sistemático empleando criterios establecidos en el protocolo PRISMA. Se seleccionaron 289 trabajos (ACM Digital Library (94), IEEE Xplorer (100) y Scopus (95)). Al aplicarse rigurosos criterios de inclusión y exclusión se escogieron 53 publicaciones. Se observa que existen resultados en esta área del conocimiento aun así, la aplicación de métodos híbridos que logre integrar sistemas de recomendación de objetos de aprendizaje adaptativos con diversas técnicas de recomendación, por ejemplo: basados por contenido, filtrado colaborativo y en ontologías, es aún incipiente. Se concluye que los pares de variables que mayor frecuencia evidenciaron fueron: VD: sistema de aprendizaje adaptativo – VI: modelo basado en ontologías difusas; VD: evaluación de habilidades – VI: modelo basado en ontologías difusas; VD: objetos de aprendizaje – VI: modelo basado en ontologías; VD: estilos de aprendizaje – VI: modelo basado en ontologías; VD: repositorios de recursos educativos digitales – VI: máquinas de soporte vectorial; VD: clasificación y agrupación de estudiantes – VI: modelo basado en ontologías.
