Authors: Caseiro Armando , Silva Ana Margarida , Ferreira Carla , Dias Beatriz , Silva Isabel , Clemente Mariana , De Figueiredo João Paulo , Pereira Telmo
Published: November 2020

Introdução: O resveratrol é uma fitoalexina natural cujos principais benefícios devem-se às suas propriedades antiinflamatórias e antioxidantes. Os seus efeitos sugerem que este é um suplemento útil para a redução da inflamação, podendo desempenhar um papel fundamental na prevenção das doenças cardiovasculares. Este promove a vasodilataçãopela indução da síntese de óxido nítrico (NO), possui atividade antitrombótica e evita a agregação plaquetária. O fator de crescimento endotelial vascular (VEGF) é responsável pela angiogénese, sendo a sua expressão influenciada pelo resveratrol. Objetivos: Avaliar o efeito do resveratrol no perfil vascular pela determinação da pressão arterial e dos biomarcadoresinterleucina-6 (IL-6), proteína C reativa (PCR), VEGF e NO. Material e Métodos: 27 alunos com idades compreendidas entre os 18 e os 22 anos foram divididos em grupo controlo (GC) e grupo de intervenção (GI), que consumiram placebo e 100 mg de resveratrol por dia, respetivamente, durante 1 mês. A pressão arterial foi medida com aparelho automáticovalidado. Os níveis de PCR foram obtidos por imunoturbidimetria, os de IL-6 e VEGF por slot blot e a quantificação de NO por espectrofotometria. Resultados: Entre os grupos observou-se uma diminuição da pressão arterial braquial e central (??0.05). A variação negativa no NO apresentou-se superior no GC apesar das diferenças não serem significativas (p>0,05). Nos restantes marcadores avaliados não se observaram diferenças significativas. Conclusões: A ingestão regular de resveratrol parece ser uma abordagem preventiva a nível vascular, dado que modula positivamente o perfil vascular, reduzindo a pressão arterial. A variação nos níveis de NO poderá ajudar a explicar os benefícios verificados.

Consumers Choosing Retailers On Online Marketplaces: How Can Retailers Differentiate Apart From The Price? – An Exploratory Investigation
Authors: Adler Manuel , Wohllebe Atilla
Published: November 2020

Online marketplaces are becoming increasingly important for many traders. At the same time, price transparency is a challenge. To secure their profit margins and to be able to convince consumers outside of pricing, it is therefore important for retailers in online marketplaces to understand which factors besides pricing influence the purchasing decision of consumers. This paper focuses therefore on situations where the decision for a certain product is already made and where consumers are only looking for the right retailer in an online marketplace. This paper uses a binary logistic regression to investigate what consumers previous experience with retailers is and how it influences them, apart from price, delivery time, ratings and the consumer's previous experience with the retailer have. The investigation is based on 700 purchase decisions collected in a survey. The paper provides important insights into which aspects retailers should focus on in order to be able to sell successfully via marketplaces even outside of a price war. In addition, the paper suggests more in-depth research questions.
Self-Perceived Readiness of Haitian Agricultural University Students to enter the Workforce: A Call for Curriculum Reform
Authors: Roberts Grady , Pierre Absalon , Gilot Anne , Bunch J.C
Published: November 2020

The country of Haiti has faced chronic food insecurity for decades. Increasing domestic food production has been identified as a key part of the solution, but this requires building human capacity, especially related to agricultural extension and research. Haiti’s agricultural universities can be key players in this process. The purpose of this study was to explore the self-perceived readiness of Haitian agricultural university students to enter the workforce. Results revealed students had a wide variety of career aspirations and appreciated the breadth of the agronomy engineer degree. Students also expressed favorable opinions about their preparedness for the job market but felt pessimistic about finding a job. Students valued the importance of research and felt prepared to lead a research project. Finally, students thought all 17 Global Forum for Rural Advisory Services (GFRAS) New Extensionist competency areas were important. Recommendations for additional research and practice are provided.

A standardized database of Marine Isotopic Stage 5e sea-level
proxies on tropical Pacific Islands
Authors: Hallmann Nadine , Camoin Gilbert , Webster Jody M. , Humblet Marc
Published: November 2020

Abstract. Marine isotope stage 5 deposits have been reported on many tropical Pacific islands. This paper presents a database compiled through the review of MIS 5e (Last Interglacial – LIG) coral reef records from islands belonging to French Polynesia (Anaa, Niau, Makatea, Moruroa, Takapoto, Bora Bora), the Hawaiian Islands (Oahu, Lana'i, Midway Atoll), Tuvalu, Kiribati (Christmas Island, Tarawa), the Cook Islands (Mangaia, Atiu, Mitiaro, Mauke, Pukapuka, Rakahanga, Rarotonga), Tonga, Samoa, the Federal States of Micronesia, the Mariana Islands, the Marshall Islands (Enewetak, Bikini), New Caledonia, Papua New Guinea, Vanuatu, Fiji and Niue. Studies reporting other sea-level indicators dated to other Pleistocene interglacials and Holocene sea-level indicators were not inserted in the database, but are included in this data description paper for completeness. Overall, about 300 studies concerning Pleistocene and Holocene sea-level indicators have been reviewed, and finally 284 data points from 35 studies on the MIS 5e have been inserted in the database. The main sea-level indicators include emerged coral reef terraces, but also reef units recovered in drill cores from a few islands, thus reflecting the diversity of tectonic settings and sampling approaches. Future research should be directed towards better constrained relative sea-level (RSL) reconstructions, including more precise chronological data, more accurate elevation measurements as well as a better refinement of the palaeo-water depth significance of coralgal assemblages. The database for Tropical Pacific Islands is available open-access at this link: http://doi.org/10.5281/zenodo.3991672 (Hallmann and Camoin, 2020).
GENETIC ALGORITHM FOR OPTIMIZING DISTRIBUTION WITH ROUTE RESTRICTION CONSTRAINT DUE TO TRAFFIC JAMS
Authors: Mouttaki N. , Benhra J. , Rguiga G.
Published: November 2020

Abstract. The Travelling Salesman Problem (TSP) is a classical problem in combinatorial optimization that consists of finding the shortest tour through all cities such that the salesman visits each city only one time and returns to the starting city. Genetic algorithm is one of the powerful ways to solve problems of traveling salesman problem TSP. The current genetic algorithm aims to take in consideration the constraints happening during the execution of genetic algorithm, such as traffic jams when solving TSP. This program has two important contributions. First one is proposing simple method into taking in consideration an inconvenient route linked to traffic jams. The second one is the use of closeness strategy during the initialization step, which can accelerate the execution time of the algorithm.The results of the experiments show that the improved algorithm works better than some other algorithms. The conclusion ends the analysis with recommendations and future works.
CONCRETE RECYCLING: SOCIAL AND ENVIRONMENTAL TECHNICAL GAIN FOR SMART CITIES
Authors: Naouaoui K. , Bouyahyaoui A. , Cherradi T.
Published: November 2020

Abstract. Recycled aggregate concrete is a new technology for using a developed type of concrete that combines technicality with the environmental and recycling aspect. It is based on the reuse of old demolished concrete in the format of new aggregates for new concrete. The main advantage of this concrete is the reuse of construction debris which is a huge management problem in addition to complying with countries' requirements for recycling rates. This technology will also solve the problem of shortage of natural resources from which many countries suffer. Thus, this new technology is at the forefront of research and improvement studies in order to identify the technical characteristics: Mechanical properties, formulation, durability ... of a new concrete based on these aggregates. Morocco, as a developing country, favors the promotion of new technologies. It is true that the Moroccan standardization does not specify recycled aggregates but the use is more and more common in the last decade mainly in road works. The structural elements of the building require further study in order to technically validate the choice of concrete.
How does the built environment affect transit use by train, tram and bus?
Authors: De Gruyter Chris , Saghapour Tayebeh , Ma Liang , Dodson Jago
Published: November 2020

While much research has explored the influence of the built environment on public transport use, little focus has been given to how this influence varies by public transport mode. Using a case study of Melbourne, this study assesses the influence of the built environment and other characteristics (transit service quality, demand management and socio-demographics) on commuting by train, tram and bus. Key findings indicate that the built environment has a significant influence, but with notable differences between individual public transport modes. Commuting by tram was found to have the strongest association with the explanatory variables, while bus had the weakest explanatory power. Differences in the geographical coverage of public transport services in Melbourne play a key role in explaining the influence of the built environment. Population density is positively associated with tram use, which operates in older, higher density environments, but is negatively associated with train and bus use. Furthermore, the association with land-use mix is only significant for train and tram use, as buses tend to operate in areas with greater land-use homogeneity. When focused on inner Melbourne only, the influence of the built environment is diluted, while distance to public transport becomes more significant. The findings have important implications for practice, not only in terms of improving transit demand forecasting but also in targeting changes to the built environment to leverage higher transit ridership by mode.
Revising the DIKW Pyramid and the Real Relationship Between Data, Information, Knowledge and Wisdom
Authors: Van Meter Heather J
Published: November 2020

This paper offers a critique and reformulation of the data-information-knowledge-wisdom (DIKW) pyramid. Today, collection of personal, business, industrial, and other types of data has never been more pervasive and invasive. Data storage now is measured in yottabytes (56 septillion bits of data) and beyond. This collected data is interrogated, monetized, hacked, and otherwise handled and mishandled around the world at an increasingly rapid pace due to improvements in technology. The interrogated data becomes information, but whether this information is useful or valuable depends entirely on the manner of interrogation and the accuracy of the underlying data. In turn, information could become knowledge but not necessarily, and not necessarily useful knowledge either. Knowledge and wisdom are also closely related, but wisdom typically contains a volume and longevity of collected knowledge and a purpose. Are humans more knowledgeable or wiser for today’s massive amounts of collected data? This paper examines the traditional DIKW pyramid and proposes a revised DIKW relationship based on a Venn diagram to better reflect the relationship between data, information, knowledge, and wisdom.
Pollution as a Paradigm: Property, Dignity, and Absorption in Poth and Tezuka
Authors: Schillings Sonja
Published: November 2020

Pollution, this article suggests, challenges the fundamental structural premises of contemporary state institutions such as the law. These institutions are based on the premise of human exceptionalism via the construction of a human-nature divide. This divide only allows one point of connection between human and nature: the human ability to absorb nature as property. Such metaphorical understandings of absorption become a problem as soon as the physical human body is faced with a situation in which we constantly absorb pollution (e.g. nitrogen oxides, microplastic, ionizing radiation, but also other life forms such as airborne viruses). As a result, contemporary institutions are ill-equipped to deal with pollution as a central element of the contemporary human condition.

This article suggests that comics are a model for rethinking these categorical issues productively and sustainably. By using visual elements, comics have already been able to reframe and recontextualize categorical premises such as the human-nature divide that otherwise tend to be reproduced in critical theory and the law. To make this point for the potential of a new categorical language that centrally draws on visual elements in text, the article uses two central examples from Japan and Germany: Osamu Tezuka's story "Space Snow Leopard" from the Astro Boy series, and Chlodwig Poth's short comic "Jörg the Limelight Hog."
Experimental Norms: Power–Knowledge, Bare Life and Medical Trials
Authors: Bikundo Edwin
Published: November 2020

Humans experimenting on other humans sits precisely at the junction of law, technology and the humanities, synthesising descriptive, normative and creative elements in relation to reality. Experiments describe reality, normalise shared conceptions of reality as well as create their own reality. Human experiments consequently inflect both ‘norm’ and ‘humanity’ as a pattern or as a model, or even a standard to be met or fulfilled. Experiments abound in Italian philosopher Giorgio Agamben’s body of work, including where he engages with the capacity for development of Michel Foucault’s opus. This is particularly so when Agamben explicitly addresses questions and criticisms surrounding his own methodology.

Published: November 2020

OBJECTIVE: To present our problematic skin wounds cases treated with PRP application of that has not responded to the treatment method. MATERIAL AND METHODS: Out of a total of 154 hospitalized patients with complex skin wounds 83 have been treated with platelet-rich plasma, comprising the Experimental group (EG), and 71 patients with comparable wounds have been treated by utilizing traditional techniques for the respective pathology, comprising the Control Group (CG). Ratings introduced by Cancela AM are used for the evaluation of the respective wound. Statistical analyzes have been performed by using the software SPSS (Statistical Package for the Social Sciences). All cases were treated in a procedure, which includes activated platelet-rich plasma. The treatment algorithm we used is as follows: first, there is surgical treatment and debridement of the wound. Activated plasma is used to infiltrate the wound edges and the fibrin clot is used to fill the wound itself. A sterile dressing soaked with physiological saline is applied. The treatment is repeated on a weekly basis until the wound problem is resolved in full. RESULTS: The results of our research indicate that 77 (92.78%) of patients enjoy a full recovery, while 6 (7.22%) of patients have no positive wound healing outcome (unhealed wound). CONCLUSION: Theoretical and clinical studies prove that the PRP method is a reliable, rational, and modern option for PSW treatment. It should not be seen as the only one and universal.
A Corpus-Based Analysis of the Lexical and Grammatical Properties of Arabic Abstracts in Social Sciences Articles
Authors: Smadi Alaa’ Mohammad
Published: November 2020

This study aims to analyze quantitatively and quantitatively Arabic journal articles’ abstracts written within the field of social sciences. It mainly aims to analyze the lexical and grammatical qualities of the abstracts in the five academic disciplines; Economy, Geography, Psychology, Sociology, and Law,. To achieve the goal of the study, a corpus consisting of 500,000 words was collected from various well-known Arabic journals, and then it was divided into five sub-corpora each of which represented one academic discipline. The Corpus Linguistics approach was applied to this study and the data were analyzed through using WordSmith tools (version 0.7). The quantitative results show that the abstracts in all disciplines show a similar word mean length, i.e. all of them is around (5). Qualitatively speaking, the results show that each discipline has its list of lexical words that are suitable for each discipline's genre. The results also reveal a small amount of variation in terms of the tense of the reporting verbs specifically those which are used in the introductory part of the abstracts. However, the reporting verbs used in the body and the concluding parts of all abstracts are characterized by the past tense, third person, and active voice.
Trade and Missionary Work: A Word Frequency Analysis of Dialogues and Detached Sentences in the Chinese Language (1816) and the Pedagogy of Robert Morrison
Authors: Luo Junjie
Published: November 2020

This paper analyzes how pedagogy is a means through which different political, economic, and cultural forces interact. I focus on one form of pedagogy—teaching Chinese as a foreign language, and use one textbook—Dialogues and Detached Sentences in the Chinese Language (1816) compiled by Robert Morrison (1782–1834)—as a case study to examine a convergence of factors that influenced the material for learning Chinese in the early nineteenth century. I combine the word frequency analysis of Dialogues and Detached Sentences in the Chinese Language and the close examination of certain translations from the textbook, and contend that this textbook reflects the diverse interests such as the urge to trade with China and the mission to spread Christianity. My paper concludes that pedagogical material is deeply rooted in its economic, political, and cultural conditions and that a synthesis of distant reading and close reading can reveal new aspects of the connection between Morrison's textbook and its historical context.
Anthropocentrism in 2001: A Space Odyssey and The Three-Body Problem
Authors: Zhao Siqi , Peng Qinglong
Published: November 2020

While both are internationally acclaimed science fiction writers with remarkable attainments, Liu Cixin says that Arthur C. Clarke has been an important influence in his work. Their thematic concerns are similar, as they both represent the awe of indeterminacy in a vast universe, but they differ in their exploration of possibilities that expose the parochiality of anthropocentrism. Clarke's, 2001: A Space Odyssey, and Liu's, The Three-Body Problem, describe scenarios where humans confront an alien civilization. This article presents a literary interpretation of these powerful alien images and their relationship with humans, which reveal the authors' ideas about anthropocentrism in the age of technology, a leading force shaping society. By contextualizing their respective cultures, we hope to impress readers with Clarke and Liu's craftsmanship in science fiction writing.
Cross-Cultural Migration and the Academic Boundaries of Comparative Literature
Authors: Zhao Weirong , Yang Qing
Published: November 2020

The increase in global population movements and migration has transformed comparative literature and generated new fields of inquiry, such as the study of diaspora, immigrant, and Chinese literatures. Although both the French and American schools of analysis have historically made important contributions to the discipline of comparative literature, the aforementioned transformations have led some scholars to critique these schools as Eurocentric, Orientalist, or Western-centric. By reviewing and comparing the development of the discipline of comparative literature, this article argues that Chinese scholars' proposals for cross-civilization and variation study of comparative literature have brought new vitality to the discipline, further expanding its academic boundaries, and making it truly open and inclusive.
Variation in Literature Communication and the Formation of World Literature
Authors: Cao Shunqing , Zhang Shuaidong
Published: November 2020

Starting with the fact that Chinese literature was absent from world literature in the twentieth century, this article reveals a contradiction in Johann Wolfgang Goethe's prediction. The line drawn between Chinese literature and world literature manifests a hierarchical structure of the existing world literature. Through a brief retrospective of Sino-Western cultural exchanges in history, we are led to the phenomenon of literary variation that usually appears when works circulate out of their original backgrounds, indicating the compatibility of heterogeneous literatures. From the perspective of Variation Theory, a new pattern of world literature's formation that differs from the core-periphery model or literary compromises may get inspired. Resorting to translative variation and thematic variation, works acquire worldness without sacrificing their national characteristics. In this case, world literature will be hopefully formed in comprehensive communications among different literatures.
Why Did Milton Land in China Earlier than Shakespeare?
Authors: Hao Tianhu
Published: November 2020

As far as we know, Milton was first introduced into China in 1832, and Shakespeare in 1839–1840. Why did Milton land in China earlier than Shakespeare? Their different routes of cultural migration into China are largely conditioned by sociohistorical forces. With keener interest in Milton for his identity as a religious poet, the Western missionaries in China cherished Milton's educational value, but were not so interested in literature per se or the entertainment value of Shakespeare. On the other hand, the Chinese educated audience seemed more captivated by the more secular and more spectacular Shakespeare, the quintessence of British cultural imperialism. In China's early reception, Shakespeare was more enjoyed as a storyteller and a dramatist. Unlike Milton, Shakespeare boasted the advantage of the stage, which makes the Bard excel his rival in their visibility in China at the turn of the twentieth century.
The Wandering Earth and China's Construction of an Alternative Cosmopolitanism
Authors: He Weihua
Published: November 2020

As an epoch-making event in the history of the Chinese sci-fi film industry, The Wandering Earth boasts the extraordinary acting skills of cinema superstars and fabulous special effects. Instead of providing a description of the technical issues surrounding the film's production, this paper looks at the film as a cultural expression and dramatization of China's reconceptualization of the notion of cosmopolitanism. After scrutinizing tianxia, which is generally taken to refer to classical Chinese cosmopolitanism, this paper goes on to describe its experiential dimension, its techno-socio-economic foundation, and its cosmopolitan solidarity as shown in the film. Finally, after analyzing the ethical dimension of the cosmopolitan community, which is embodied in the idea of “home” in the film, the paper concludes by proposing a cosmopolitanism of ethicality.

Mental Space Theory on Presupposition Projections in Advertisements
Authors: Guo Ling
Published: November 2020

In this economic society in which information is prevailing, advertisements are found here and there, and play a very important role in our daily life. More and more importance is attached to the research of advertising language. This paper reveals presupposition projection problems in advertising, especially in English advertising. It aims to explore the explanation of mental space theory for cancellation or inheritability of presupposition in advertising, that is, the projection problem of presupposition. Different from how traditional presupposition theory is used in seeking for a reasonable explanation for projection problems, this paper will investigate in detail projection problems in advancing from the perspective of Fauconnier's mental space theory in combination with large quantities of advertisement examples.
Reflecting on Personal Routines to New Ways of Teaching by German Geography Teachers: Effects of a Teacher Training Project in North Rhine-Westphalia
Authors: Krohmer Maxim , Budke Alexandra
Published: November 2020

The gap between educational knowledge that is taught in universities and actions by teachers can be sizeable. A sustainable change in teachers' efforts requires particular sensitivity and awareness of this gap between subject-specific educational thinking and acting and between theory and practice. This study explored the extent to which a reflection on personal routine in class undertaken by geography teachers, and the associated awareness of their deficits ("the gap"), can contribute to a change in action. In this study, ten teachers from German Gymnasiums in North Rhine-Westphalia participated in a four-month-long intervention. The teachers had to document their lessons, work through possible deficits in peer discussions, and discuss solutions. The results showed that although intervention helped raise awareness of deficits, it was not enough to bring about a lasting change in teachers' actions. Possible causes for this lack of lasting change are reflected upon, and teacher training consequences are considered.
Company legitimacy and Sustainable Operations: The Case of Apparel Manufacturers of Sri Lanka

Published: November 2020

In the highly sustainability conscious business environment, organizations face the pressure of their stakeholders to carryout sustainable operations. In this context organizations take many sustainability measures to make themselves socially responsible. Literature suggests that the power of the stakeholder determines the extent to which an organization adheres to stakeholder requirements due to their dependence on such stakeholders. Therefore whether the behaviours of organizations towards sustainability could be treated as ‘socially responsible’ and whether they really fulfill the social contract they have entered into, become questionable. A qualitative study was carried out based on in depth interviews with senior managers of four apparel manufacturing and exporting firms of Sri Lanka to investigate how organizations in a developing country fulfill their social contract towards sustainability in international operations since these firms operate with powerful international customers. The thematic analysis conducted based on the interview data of the apparel manufacturers of Sri Lanka reveal a similarity in the results to what has been identified in literature in relation to the manner manufacturers respond to stakeholder requirements. The extent to which they meet the requirements of their stakeholders has been confined to just a legal requirement to satisfy the powerful customers. Although there was legitimacy in their behavior it raised doubts for the researcher about the fulfillment of the social contract through this behavior since these manufacturers were not concerned about certain aspects of sustainability which the customers were not interested in. One such main factor was the sustainability of their suppliers. These findings inform policymakers the need to educate the apparel exporters of their responsibility towards sustainability because the social acceptability that comes with legitimacy may be more important than economic viability. The contribution of this study to knowledge is in terms of how the dependence of manufacturers in developing countries, influence their adherence to stakeholder requirements.

Authors: Yalçın Mustafa , Laçin Nihat
Published: November 2020

Purpose: The aim of this study was to evaluate the prevalence of antral pseudocysts(AP), maxillary sinus septas(MSS) and the relationship between AP and MSS by using cone-beam computed tomography(CBCT).Methodology: The CBCT scans of 466 patients (237 male, 229 female ranging in age between 13 and 83) were included in our study. The presence or absence of AP and MSS were confirmed at axial, sagittal, and coronal sections of CBCT images by considering gender and localization. For statistical analysis, Pearson chi-square and Spearman correlation tests were used.Results: One hundred-ninety eight out of 466 (42.49%) patients had AP in the right and left maxillary sinus. There was a significant difference in the prevalence of AP between men and women (p≤0.001). The prevalence of AP was higher in men than in women. Twenty-eight out of 237 patients in men(11.81%) and 35 out of 229 patients in women(15.28%) had MSS in the right and left maxillary sinus. Conclusion: The prevalence of AP and MSS was 42.49% and 13.52%, respectively and the prevalence of MSS was lower in our study than other studies. We did not determine the relationship between AP and MSS in the maxillary sinuses.

Este trabalho relata a avaliação diagnóstica de estudantes de um curso de Sistemas de Informação (SI) apoiada por um sistema Web, chamado Questione, que armazena e indexa questões com estruturas semelhantes às questões aplicadas no Enade. O artigo relata a evolução dos estudantes com relação às competências mensuradas e como esses dados serviram para a tomada de decisão de um curso de SI, por meio do feedback coletado com os professores que participaram do processo. Ao analisar todos os elementos desta pesquisa, pode-se concluir que o sistema Questione foi fundamental para sistematizar a avaliação diagnóstica, permitindo que a catalogação das questões e a aplicação dos simulados se tornasse uma tarefa simples e rotineira dentro do curso.

O ensino de Física pode ser considerado difícil devido a tantos cálculos, gráficos e números. Às vezes, a capacidade de associação das fórmulas e do conteúdo teórico com o cotidiano não acontece de forma clara pra os alunos. Além disso, o ensino de Programação de Computadores também se torna difícil para os alunos, pois muitas vezes lhes faltam habilidades de resolverem problemas por meio de um computador. Logo, o objetivo deste trabalho é facilitar o ensino de Física e Programação de Computadores por meio da Cultura Maker, no processo faça-você-mesmo (DIY). Como estudo de caso, criamos uma estação meteorológica portátil com Arduino, de forma que os alunos pudessem relacionar assuntos de Termodinâmica com Programação de Computadores, buscando melhorar a forma de raciocínio e visibilidade com o auxílio da Física teórica, a Cultura Maker e o cotidiano. Nesse experimento, participaram alunos do segundo ano de um curso técnico de Ensino Médio em Eletrônica. Os resultados obtidos e o relato das experiências mostram a viabilidade da proposta.

Este estudo buscou investigar ações de uma oficina ofertada para docentes, por meio da busca e da análise de Recursos Educacionais Digitais (RED) de Língua Portuguesa e de Matemática, a partir do repositório educacional digital Athena. A oficina foi organizada em três momentos: 1) Contextualização teórica; 2) Apresentação de critérios técnico-pedagógicos; 3) Seleção de RED por meio do repositório trabalhado. Os resultados evidenciam a relevância do momento formativo para a apropriação e compreensão no que tange à busca e à análise dos recursos pelos professores. Além disso, as escolhas e as explorações dos RED demonstram particularidades quanto às práticas dos professores, contextualizadas às suas realidades e necessidades.

Diante do cenário de distanciamento social ocasionado pela pandemia da COVID-19, houve urgência na busca pela adaptação de métodos de ensino mediados pelas tecnologias digitais. Nesse sentido, este artigo relata o caminho percorrido por uma escola pública municipal, nos anos finais do ensino fundamental, para que o acesso à educação básica pudesse ser mantido nesse momento. A metodologia parte do princípio descritivo, narrando as principais ações para o desenvolvimento do trabalho. Os resultados são parciais, uma vez que o processo está ocorrendo, entretanto, busca-se compartilhar as experiências nesse novo cenário, fomentando ideias de recursos computacionais e vivências pedagógicas práticas.
Educação Básica Inclusiva: Mapeamento sistemático sobre a utilização de recursos tecnológico no letramento de pessoas com deficiência auditiva
Authors: Saraiva Juliana , Aguiar Yuska
Published: November 2020

Num cenário de constantes modificações e consequente necessidade de atualizações informacionais, o papel do Letramento Informacional é primordial para permitir aos indivíduos resolver problemas cotidianos e se adaptar às transformações. Todavia, sabendo-se que o letramento só acontece com a utilização social da escrita e da leitura, e que este processo utiliza-se da emissão de sons como parte importante na comunicação, as Pessoas com Deficiência Auditiva (PcDA) enfrentam dificuldades. Neste sentido, o Decreto nº 5.626 direciona iniciativas na educação bilíngue de surdos com LIBRAS. Por outro lado, aliado ao processo de facilitador da educação inclusiva, a tecnologia digital assistiva proporciona a ampliação da mobilidade, comunicação e habilidades de aprendizado. Sob esta perspectiva, a academia, indústria e o Poder Público unem esforços para fomentar políticas públicas que subsidiem a inclusão e acesso a um ensino gratuito e de qualidade. Tendo em vista a carência de informações acerca do desenvolvimento e implantação de soluções de tecnologia digital que dêem suporte ao letramento de PcDA nas escolas públicas no Brasil, realizou-se um mapeamento sistemático da literatura em 17 bases de artigos, buscando evidências sobre implantação desta neste contexto. Levando em consideração a literatura recente (2013-2017), observou-se uma defasagem no desenvolvimento de soluções tecnológicas com este propósito, além de comprovações superficiais sobre sua eficácia. Adicionalmente, há uma carência de informações relevantes sobre os recursos digitais assistivos apresentados nos artigos analisados, como custo de aquisição, tipo de licença, disponibilidade para download e processo de adoção.

Viva la Transición
Authors: Solioz Christophe
Published: November 2020

The author argues, first, that transition—characterised by instability, movement, alterations and ruptures—becomes the rule of any society, not exclusively that of ‘transitional societies’. And, secondly, away from the sequencing theorised in democratisation studies (e.g. accommodation, liberalisation, transition, consolidation), transition points tentatively to a new era characterised by a drive, a movement that empowers a society creatively to self-constitute. In a ceaseless participatory process, each polity assembles, adjusts, fabricates and constructs itself as a society. Instead of disenchantment and collapse, ‘democratic indetermination’ and the ‘politics of dwelling’ are the factors which shape a truly effective and open democracy. Transition, therefore, is an uncharted journey in the land of democracy.
