O novo direito da Energia Atômica
Authors: Puget Henry , IBCA Inst. Brasileiro de Ciências Administrat
Published: November 2020

A conquista da energia atômica e suas formas de utilização suscitam, no mundo atual, um sentimento de esperança, de orgulho e, sobretudo, de angústia. Essa espantosa força de que os homens doravante dispõem inquieta-nos e dela nos ocupamos, procurando conhecê-la melhor. Gostaríamos de subjugá-la mais ainda, para cada vez mais dela tirar o melhor partido ou, se tivermos que empregá-la contra um inimigo, o pior partido. A julgar pelas possibilidades que ela oferece para o mal, o progresso foi demasiado prodigioso e rápido, mas, considerados em conjunto, os avanços realizados ou previstos não nos oferecem apenas destruição e desde logo nos conduzem a melhores resultados, abrem para o futuro outras perspectivas. Quando, há alguns anos, conversava sobre o que então não passava de um simples projeto, a instalação de uma pilha atômica em Saclay, o Sr. Joliot -Curie declarou-me que nos encontrávamos às vésperas de mudanças só comparáveis, em grandeza, às que presenciou o gênero humano com a descoberta do fogo.
Digital Health Interventions for People With Type 2 Diabetes to Develop Self-Care Expertise, Adapt to Identity Changes, and Influence Other’s Perception: Qualitative Study
Authors: Turnbull Sophie , Lucas Patricia J , Hay Alastair D , Cabral Christie
Published: November 2020

Background

A diagnosis of type 2 diabetes (T2D) results in widespread changes to a person’s life and can be experienced as an assault on their sense of self. The resources available to an individual influence how the individual adapts to their diabetic identity and subsequently engages in self-care. Digital interventions can be viewed as a resource that people can draw on to adapt to the diagnosis. However, there is an indication that people from disadvantaged groups find digital health technologies more challenging to access and use, which may increase health inequalities.

Objective

This study aims to gain insights into how and why people with T2D use digital self-care technology and how experiences vary between individuals and social groups.

Methods

A purposive sample of people who had used a digital intervention to help them self-care for their T2D were recruited for the study. Semistructured interviews were conducted, and data were analyzed thematically.

Results

A diverse sample of 21 participants were interviewed. Participants used digital interventions to help them to understand and feel more in control of their bodies. Digital interventions were used by participants to project their chosen identity to others. Participants selected technology that allowed them to confirm and enact their preferred positive identities, both by avoiding stigma and by becoming experts in their disease or treatment. Participants preferred using digital interventions that helped them conceal their diabetes, including by buying discrete blood glucose monitors. Some participants used technology to increase their sense of power in their interaction with clinicians, whereas others used technology to demonstrate their goodness.

Conclusions

The technology that people with T2D have access to shapes the way they are able to understand and control their bodies and support preferred social identities.

Authors: Campbell Narelle , Farthing Annie , Witt Susan , Anderson Jessie , Lenthall Sue , Moore Leigh , Rissel Chris
Published: November 2020

Background

The successful recruitment and retention of health professionals to rural and remote areas of Australia is a health policy priority. Nursing or allied health professional students’ learning placements in the Northern Territory (NT) of Australia, most of which is considered remote, may influence rural or remote work location decisions.

Objective

The aim of this study is to determine where allied health professionals and nurses who have had a student placement in the NT of Australia end up practicing.

Methods

This research is an observational cohort study, with data collection occurring at baseline and then repeated annually over 10 years (ie, 2017-2018 to 2029). The baseline data collection includes a demographic profile of allied health and nursing students and their evaluations of their NT placements using a nationally consistent questionnaire (ie, the Student Satisfaction Survey). The Work Location Survey, which will be administered annually, will track work location and the influences on work location decisions.

Results

This study will generate unique data on the remote and rural work locations of nursing and allied health professional students who had a placement in the NT of Australia. It will be able to determine what are the most important characteristics of those who take up remote and rural employment, even if outside of the NT, and to identify barriers to remote employment.

Conclusions

This study will add knowledge to the literature regarding rates of allied health and nursing professionals working in remote or rural settings following remote or rural learning placements. The results will be of interest to government and remote health workforce planners.

Authors: Lin Min-Qiang , Lian Chen-Lu , Zhou Ping , Lei Jian , Wang Jun , Hua Li , Zhou Juan , Wu San-Gang
Published: November 2020

Background

The application of China’s big data sector in cancer research is just the beginning. In recent decades, more and more Chinese scholars have used the Surveillance, Epidemiology, and End Results (SEER) database for clinical cancer research. A comprehensive bibliometric study is required to analyze the tendency of Chinese scholars to utilize the SEER database for clinical cancer research and provide a reference for the future of big data analytics.

Objective

Our study aimed to assess the trend of publications on clinical cancer research in mainland China from the SEER database.

Methods

We performed a PubMed search to identify papers published with data from the SEER database in mainland China until August 31, 2020.

Results

A total of 1566 papers utilizing the SEER database that were authored by investigators in mainland China were identified. Over the past years, significant growth in studies based on the SEER database was observed (P<.001). The top 5 research topics were breast cancer (213/1566, 13.6%), followed by colorectal cancer (185/1566, 11.8%), lung cancer (179/1566, 11.4%), gastrointestinal cancer (excluding colorectal cancer; 149/1566, 9.5%), and genital system cancer (93/1566, 5.9%). Approximately 75.2% (1178/1566) of papers were published from the eastern coastal region of China, and Fudan University Shanghai Cancer Center (Shanghai, China) was the most active organization. Overall, 267 journals were analyzed in this study, of which Oncotarget was the most contributing journal (136/267, 50.9%). Of the 1566 papers studied, 585 (37.4%) were published in the second quartile, 489 (31.2%) in the third quartile, 312 (19.9%) in the first quartile, and 80 (5.1%) in the fourth quartile, with 100 (6.4%) having an unknown Journal Citation Reports ranking.

Conclusions

Clinical cancer research based on the SEER database in mainland China underwent constant and rapid growth during recent years. High-quality and comprehensive cancer databases based on Chinese demographic data are urgently needed.

Using Social Media to Understand Web-Based Social Factors Concerning Obesity: Systematic Review (Preprint)
Authors: Li Chuqin , Ademiluyi Adesoji , Ge Yaorong , Park Albert
Published: November 2020

BACKGROUND

Evidence in the literature surrounding obesity suggests that social factors play a substantial role in the spread of obesity. Although social ties with a friend who is obese increase the probability of becoming obese, the role of social media in this dynamic remains underexplored in obesity research. Given the rapid proliferation of social media in recent years, individuals socialize through social media and share their health-related daily routines, including dieting and exercising. Thus, it is timely and imperative to review previous studies focused on social factors in social media and obesity.

OBJECTIVE

This study aims to examine web-based social factors in relation to obesity research.

METHODS

We conducted a systematic review. We searched PubMed, Association for Computing Machinery, and ScienceDirect for articles published by July 5, 2019. Web-based social factors that are related to obesity behaviors were studied and analyzed.

RESULTS

In total, 1608 studies were identified from the selected databases. Of these 1608 studies, 50 (3.11%) studies met the eligibility criteria. In total, 10 types of web-based social factors were identified, and a socioecological model was adopted to explain their potential impact on an individual from varying levels of web-based social structure to social media users’ connection to the real world.

CONCLUSIONS

We found 4 levels of interaction in social media. Gender was the only factor found at the individual level, and it affects user’s web-based obesity-related behaviors. Social support was the predominant factor identified, which benefits users in their weight loss journey at the interpersonal level. Some factors, such as stigma were also found to be associated with a healthy web-based social environment. Understanding the effectiveness of these factors is essential to help users create and maintain a healthy lifestyle.
Quantifying the Influence of Delay in Opinion Transmission of COVID-19 Information Propagation: Modeling Study (Preprint)
Authors: Yin Fulian , Shao Xueying , Ji Meiqi , Wu Jianhong
Published: November 2020

BACKGROUND

In a fast-evolving public health crisis such as the COVID-19 pandemic, multiple pieces of relevant information can be posted sequentially on a social media platform. The interval between subsequent posting times may have a different impact on the transmission and cross-propagation of the old and new information that results in a different peak value and a final size of forwarding users of the new information, depending on the content correlation and whether the new information is posted during the outbreak or quasi–steady-state phase of the old information.

OBJECTIVE

This study aims to help in designing effective communication strategies to ensure information is delivered to the maximal number of users.

METHODS

We developed and analyzed two classes of susceptible-forwarding-immune information propagation models with delay in transmission to describe the cross-propagation process of relevant information. A total of 28,661 retweets of typical information were posted frequently by each opinion leader related to COVID-19 with high influence (data acquisition up to February 19, 2020). The information was processed into discrete points with a frequency of 10 minutes, and the real data were fitted by the model numerical simulation. Furthermore, the influence of parameters on information dissemination and the design of a publishing strategy were analyzed.

RESULTS

The current epidemic outbreak situation, epidemic prevention, and other related authoritative information cannot be timely and effectively browsed by the public. The ingenious use of information release intervals can effectively enhance the interaction between information and realize the effective diffusion of information. We parameterized our models using real data from Sina Microblog and used the parameterized models to define and evaluate mutual attractiveness indexes, and we used these indexes and parameter sensitivity analyses to inform optimal strategies for new information to be effectively propagated in the microblog. The results of the parameter analysis showed that using different attractiveness indexes as the key parameters can control the information transmission with different release intervals, so it is considered as a key link in the design of an information communication strategy. At the same time, the dynamic process of information was analyzed through index evaluation.

CONCLUSIONS

Our model can carry out an accurate numerical simulation of information at different release intervals and achieve a dynamic evaluation of information transmission by constructing an indicator system so as to provide theoretical support and strategic suggestions for government decision making. This study optimizes information posting strategies to maximize communication efforts for delivering key public health messages to the public for better outcomes of public health emergency management.
Development of a Quality Assurance Score for the Nigeria AIDS Indicator and Impact Survey (NAIIS) Database: Validation Study (Preprint)
Authors: Salihu Hamisu M , Yusuf Zenab , Dongarwar Deepa , Aliyu Sani H , Yusuf Rafeek A , Aliyu Muktar H , Aliyu Gambo
Published: November 2020

BACKGROUND

In 2018, Nigeria implemented the world’s largest HIV survey, the Nigeria AIDS Indicator and Impact Survey (NAIIS), with the overarching goal of obtaining more reliable metrics regarding the national scope of HIV epidemic control in Nigeria.

OBJECTIVE

This study aimed to (1) describe the processes involved in the development of a new database evaluation tool (Database Quality Assurance Score [dQAS]) and (2) assess the application of the dQAS in the evaluation and validation of the NAIIS database.

METHODS

The dQAS tool was created using an online, electronic Delphi (e-Delphi) methodology with the assistance of expert review panelists. Thematic categories were developed to form superordinate categories that grouped themes together. Subordinate categories were then created that decomposed themes for more specificity. A validation score using dQAS was employed to assess the technical performance of the NAIIS database.

RESULTS

The finalized dQAS tool was composed of 34 items, with a total score of 81. The tool had 2 sections: validation item section, which contains 5 subsections, and quality assessment score section, with a score of “1” for “Yes” to indicate that the performance measure item was present and “0” for “No” to indicate that the measure was absent. There were also additional scaling scores ranging from “0” to a maximum of “4” depending on the measure. The NAIIS database achieved 78 out of the maximum total score of 81, yielding an overall technical performance score of 96.3%, which placed it in the highest category denoted as “Exceptional.”

CONCLUSIONS

This study showed the feasibility of remote internet-based collaboration for the development of dQAS—a tool to assess the validity of a locally created database infrastructure for a resource-limited setting. Using dQAS, the NAIIS database was found to be valid, reliable, and a valuable source of data for future population-based, HIV-related studies.
Analyzing Mediterranean diet on Twitter: a 11-year analysis of tweets from the major US media outlets. (Preprint)
Authors: Alvarez-Mon Miguel Angel , Fernandez Lazaro Cesar , Llavero-Valero Maria , Alvarez-Mon Melchor , Mora Samia , Martinez-Gonzalez Miguel Angel , Bes-Rastrollo Maira
Published: November 2020

BACKGROUND

Background: Media outlets influence social attitudes toward health habits. Analysis of tweets has become a tool for health research and dissemination of public health information.

OBJECTIVE

Objective: The objective of this study was to investigate the distribution of tweets about Mediterranean diet (MedDiet) and the interest generated among Twitter users.

METHODS

Methods: We investigated tweets posted between January 2009 and December 2019 by 25 major US media outlets about MedDiet and its components as well as the retweets and likes generated. In addition, we measured the sentiment analysis of these tweets and their dissemination.

RESULTS

Results: In total, 1,608 tweets, 123,363 likes and 48,946 retweets about MedDiet or its components were analyzed. Dairy (usually negatively weighted in MedDiet scores) accounted for 723 tweets (45.0%), followed by nuts 317 (19.7%). MedDiet, as an overall dietary pattern, generated only 157 (9.8%) of the total tweets, while olive oil generated the least number of tweets (31 tweets or 1.9%). Twitter users’ response was quantitatively related to the number of tweets posted by these US media outlets, except for tweets on olive oil and MedDiet as a whole: none of the MedDiet components analyzed was more likely to be liked or retweeted than the MedDiet itself. Between 2009 and 2019, there was progressive increase in the number of tweets and retweets on MedDiet and its components.

CONCLUSIONS

Conclusions: The US media outlets analyzed showed reduced interest in MedDiet as a whole, while Twitter users showed greater interest in the overall dietary pattern than in its particular components.
Development of a Resource Guide to Support the Engagement of Mental Health Providers and Patients With Digital Health Tools: Multimethod Study (Preprint)
Authors: Strudwick Gillian , McLay David , Lo Brian , Shin Hwayeon Danielle , Currie Leanne , Thomson Nicole , Maillet Éric , Strong Vanessa , Miller Alanna , Shen Nelson , Campbell Janis
Published: November 2020

BACKGROUND

As mental illness continues to affect 1 in 5 individuals, and the need for support has increased during the COVID-19 pandemic, the promise of digital mental health tools remains largely unrealized due to a lack of uptake by patients and providers. Currently, most efforts on supporting the uptake of digital mental health tools remain fragmented across organizations and geography. There is a critical need to synthesize these efforts in order to provide a coordinated strategy of supporting the adoption of digital mental health tools.

OBJECTIVE

The specific aim of this project is to develop a web-based resource document to support the engagement of mental health providers and patients in the use of digital mental health tools.

METHODS

The web-based resource was developed using a multimethod approach. A grey literature review was conducted in 2019 to identify relevant toolkits that are available in the public domain. This was supplemented with an environmental scan where individuals with expertise in the development, acquisition, implementation, and evaluation of digital mental health tools were invited to contribute additional tools or documents not identified in the grey literature search. An engagement workshop was held with stakeholders to explore how the resource document should be developed and delivered. These findings were collectively used to develop the final iteration of the resource document.

RESULTS

Based on a gray literature review and environmental scan with 27 experts, 25 resources were identified and included in the resource guide. These resources were developed for patients and providers by organizations from 5 countries. An engagement workshop was held with 14 stakeholders, and barriers related to cultural sensitivity, sustainability, and accessibility of the toolkit were identified. The final iteration of the resource document was developed by the research team using findings from the gray literature review, environmental scan, and engagement workshop. The contents of the 45-page resource guide are directed at mental health care providers, administrators, and patients (inclusive of families and caregivers).

CONCLUSIONS

The use of a multimethod approach led to the development of a resource guide that builds on existing evidence on digital mental health tools and was co-designed with stakeholders and end-users. The resource guide is now publicly available online for free and is being promoted through digital health and mental health websites. Future work should explore how this document can be integrated into clinical care delivery and pathways.

Разработан программный комплекс для проектирования прямозубых конических передач с локализованным контактом. Предложена методика построения 3D-моделей активных поверхностей зубьев, обеспечивающая получение требуемой локализации контакта. Одно из колес передачи выполнено с эвольвентными прямыми зубьями. Выбор боковых поверхностей зубьев сопряженного колеса для реализации локализованного контакта осуществляется на основе решения задачи условной оптимизации. Представлен алгоритм оценки характеристик зацепления и контакта в модифицированной передаче. Целевой функцией, подлежащей минимизации, является максимальное контактное давление в период работы одной пары зубьев. Варьируемыми являются параметры синтеза, определяющие положение центра локализованного пятна контакта и его размеры. Ограничением при решении задачи выступает предотвращение кромочного контакта. Предложен итерационный эвристический алгоритм для решения задачи минимизации целевой функции. В начале работы алгоритма выбирается начальная точка. На каждой итерации с некоторым шагом рассчитываются несколько точек кандидатов для следующего начального приближения. Переход совершается в ту точку с наименьшим значением целевой функции, где отсутствует кромочный контакт. При невозможности перехода уменьшается шаг для расчета точек-кандидатов. Алгоритм завершает работу при невозможности найти подходящую точку или слишком малом шаге. Дан пример расчета.
Guiding a Better Experiential Learning Journey by Making It HIP Again
Authors: Endersby Lisa , Maheux-Pelletier Geneviève
Published: November 2020

The definition of experiential education (EE) has both pedagogical and practical implications for higher education institutions. While there is increasing pressure to justify and quantify these experiences, we remain faced with the challenge of ensuring a demonstration of breadth does not distract from the importance of meaningful depth in and for student learning. This paper presents a potential reframing of conversations about experiential education, emphasizing the role of high impact practices (HIPs) in defining EE as more than an experience. The value, purpose, and challenges of integrating reflection into these experiences is highlighted through the lens of the defining characteristics of HIPs, supporting the development of meaningful, engaging opportunities for deeper learning.

 

La définition de l’enseignement fondé sur l’expérience (EE) est importante à la fois pour l’aspect pédagogique et pour l’aspect pratique de l’enseignement supérieur. Même si de plus en plus de voix réclament une clarification et une quantification de ce type d’expérience, la difficulté demeure la même : en démontrant l’étendue de l’expérience, il faut se garder de négliger la profondeur de l’apprentissage, qui est importante et chargée de sens. Dans notre article, nous proposons une avenue possible pour déplacer la conversation au sujet de l’enseignement fondé sur l’expérience en mettant l’accent sur le rôle des pratiques à incidence élevée dans l’EE conçu comme une notion dépassant celle d’expérience. Pour comprendre quelle valeur, quel but et quelles difficultés émergent de l’intégration de la réflexion à l’expérience, nous observons les choses à partir des traits caractéristiques des pratiques à incidence élevée de manière à rassembler les conditions pour un apprentissage en profondeur motivant et enrichissant.

O artigo parte da compreensão de que escolas são espaços de produção de conhecimentos, sentidos e valores que tensionam a hegemonia na produção dos currículos. Compartilha do entendimento de que os saberes docentes produzem e operam redes de fazeressaberes que se constituem ao longo das trajetórias e em múltiplos contextos com os quais nos tornamos professores. Traz para a discussão resultados de pesquisa articulada a um projeto de extensãorealizado com professores da Educação Básica – Anos Iniciais do Ensino Fundamental – em escolas de rede pública de dois municípios do Rio de Janeiro. Através do trabalho com narrativas docentes discute a contribuição da produção de práticas formativas e curriculares mais solidárias e democráticas como formas de resistências a partir do cotidiano das escolas, produzindo conhecimentos que contribuam com uma formação de professores comprometida com a justiça cognitiva e social. A partir da pesquisa, se discutem caminhos teórico-metodológicos com os currículos, problematizados em processos de formação coletivos com os professores e pensados diante das imprevisibilidades, heterogeneidades e complexidade dos cotidianos escolares. Dentre os métodos priorizados para o desenvolvimento da pesquisa, adotamos estratégias de estudo e intervenção que incluem rodas de conversa e produção de narrativas (escritas e orais) que trazem à tona as redes de produção de saberes entre os professores.

CURRÍCULO, TÁTICAS, RESISTÊNCIAS
Authors: Baroni Patrícia Raquel , Conceição Deise Guilhermina da
Published: November 2020

O presente artigo propõe a pesquisa de táticas (CERTEAU, 1994) utilizadas por estudantes egressos negros da periferia do Rio de Janeiro que abarcam a resistência diária às regulações autoritárias decorrentes do racismo estrutural que marca a sociedade brasileira (ALMEIDA, 2019). Tais estudantes elencam suas trajetórias para concluir a educação básica, o acesso ao ensino superior, a mobilidade social oportunizada pela formação, apesar do contexto autoritário a que são submetidos. Neste texto, a reflexão sobre o currículo e as táticas se faz a partir do processo de escolarização de três praticantespensantes, que foram aprovados no exame vestibular da Universidade Federal Fluminense (UFF) para o ano de 2004, destacando as maneiras de fazer desses sujeitos que se inscrevem como resistências aos entraves vivenciados. O repertório de narrativas oportunizado nos conduziu à identificação de três categorias de táticas: (1) a escolha acadêmica e profissional como tática de empregabilidade, (2) o acesso a ferramentas e a tessitura de redes de apoio como tática de superação das desvantagens sociais e econômicas produzidas pelo racismo estrutural e (3) a desnaturalização de práticas racistas e a identificação do racismo e do preconceito como tática de referencialidade para as lutas atuais contra processos regulatórios. Adotamos como caminho metodológico a pesquisa narrativa. Como conclusões, destacamos que o compartilhamento de narrativas de enfrentamento do racismo são potentes instrumentos para as reflexões acerca das manifestações singulares do racismo na vida dos interlocutores, inclusive, das nossas próprias vidas enquanto autoras deste artigo. Essas reflexões amplificam modos de resistência para a luta antirracista.
O CURRÍCULO ALINHADO

Published: November 2020

Há mais de um século a burocracia se destina a organizar a vida moderna, urbana, industrial. Justificada pela eficiência, primazia da ordem e liquidez, a burocracia adentra quase todos os recônditos da vida humana, interferindo e alterando a vida cotidiana e, no que diz respeito a este artigo, o cotidiano escolar. Através de diferentes entradas, a burocracia se imiscui e instala-se na escola, acionando o controle e a regulação. O objetivo deste artigo é participar da discussão acerca da burocracia direcionada aos currículos escolares. A cartografia foi empregada enquanto orientação metodológica no movimento criativo de produção do material de estudo, o qual atravessou criticamente o consumo dos códigos alfanuméricos presentes na Base Nacional Comum Curricular para encontra-los no material didático, na formação continuada e nas conversações entre as professoras. O estudo aponta que os códigos alfanuméricos, entendidos enquanto sistema de símbolos, têm por destino a obsolescência, uma vez que não são provenientes dos currículos praticados nas escolas, e porque desprovidos de sentido.
A A CONCEPÇÃO DE CURRÍCULO NOS MATERIAIS FORMATIVOS DO PNAIC
Authors: Souza Nathália Cristina Amorim Tamaio de , Guedes-Pinto Ana Lúcia
Published: November 2020

Este artigo discorre sobre a concepção de currículo escolar discutida nos materiais formativos que embasam a proposta do Pacto Nacional pela Alfabetização na Idade Certa (PNAIC) e as relações entre suas prescrições didático-metodológicas e os usos que os sujeitos praticantes – compreendidos como professores que atuam especificamente nos anos iniciais do Ensino Fundamental – podem fazer delas. Para sua realização, lançou-se mão do estudo sistemático dos cadernos que pautam as formações continuadas à luz de pesquisas que investigam os cotidianos, valendo-se especialmente das contribuições de Michel de Certeau. A linha de argumentação desenvolvida sugere como principais apontamentos: a) a validade das prescrições, dado que os professores buscam elementos norteadores para oxigenarem suas práticas; e, ao mesmo tempo b) a existência de astúcias e “artes de fazer” que permeiam o cotidiano escolar e possibilitam que essas prescrições sejam constantemente reinventadas.
CONTOS DE FADAS CONTEMPORÂNEOS E ROTEIROS PERFORMÁTICOS DE GÊNERO
Authors: Vasconcelos Maria Beatriz , Myrrha Ferreira Paula , Rezende Sales Shirlei , Caldeira Maria Carolina
Published: November 2020

Este artigo analisa dois contos de fadas contemporâneos para problematizar as prescrições de feminilidades presentes nas histórias clássicas dos contos de fadas e nos discursos reacionários que circulam na atualidade. Argumentamos, a partir do conceito de performatividade de Judith Butler, que, por um lado, a ofensiva antigênero prescreve que a mulher deve ser princesa e coloca em circulação um discurso reacionário que produz modos autorizados de se performar o gênero em conformidade com os contos de fadas tradicionais. Por outro lado, como forma de resistência, alguns contos de fadas contemporâneos tensionam as normas de gênero e acionam o discurso multicultural para re-existirem ao discurso reacionário ao produzirem modos outros de ser princesa. O referencial teórico se fundamentou na concepção de que o currículo é cultural, é um discurso que produz, autoriza, cria saberes e se desdobra em diferentes pedagogias. Nesse sentido, as narrativas dos contos de fadas, tão presentes no currículo endereçado a crianças, compõem um certo roteiro com relação às aprendizagens de gênero. Elas ensinam, há muito, normas para meninas e meninos, prescrevendo feminilidades e masculinidades tidas como normais. Mas, também podem ser potentes instrumentos para problematizar essas mesmas normas. Nas histórias analisadas é possível perceber a reivindicação de outros “atos performáticos de gênero” (BUTLER, 2019) em relação aos roteiros vividos pela princesa. A trajetória metodológica se deu por meio da análise de discurso de inspiração foucaultiana e mostrou que as narrativas fabricam modos outros de apresentar os comportamentos da princesa e pluralidade na caracterização dos corpos das personagens.
ENSINO MÉDIO NOTURNO

Published: November 2020

A questão do Ensino Médio no Brasil nunca foi um ponto de acordo entre os diversos atores envolvidos no processo. Isso porque há perspectivas diferentes de compreensão das funções e objetivos desse segmento da educação básica. As reflexões presentes neste texto fazem parte da pesquisa de mestrado finalizada e tem como objetivo produzir conhecimentos sobre o Ensino Médio Noturno (EMN), e contribuir para a discussão acerca de práticas político-pedagógicas e suas relações com as condições de vida e aprendizagem desses estudantes, buscando refletir sobre suas práticas curriculares e uma possível propagação das redes de saberesfazeres voltadas à formação desses estudantes, para assim colaborar para a inclusão social e educacional deles. Uma vez que o EMN não vem sendo contemplado, em suas especificidades, nas discussões da Educação Básica. Buscamos pistas para compreender de que modo, em uma escola estadual noturna, na Zona Norte do município do Rio de Janeiro, são concebidas e concretizadas as práticas curriculares em suas diversas dimensões. E para isso, traremos uma narrativa feita a partir da observação do movimento cotidiano no espaçotempo pesquisado. De forma a desinvisibilizar tais práticas, e destacar seu potencial criativo e produtor de emancipação social.

Steviol glycosides, mostly extracted from Stevia rebaudiana Bertoni, are
non-caloric, safe natural sweeteners. Steviosides make up more than 50%
of total steviol glycosides but possess a bitter aftertaste, which
limits their application as food additives. Trace amounts of rubusosides
are acceptable sweeteners, but their supply is limited. In this study,
we screened an endophytic bacteria (Lelliottia LST-1) that can
specifically convert stevioside into rubusoside and reach a conversion
rate of 75.4% after response surface optimization. Potential
β-glucosidases GH3-1, GH3-2, GH3-3, and GH3-4 based on whole genome
sequencing were expressed and interacted with steviol glycosides to
explore principle and process of biological transformation.
High-performance liquid chromatography revealed that all enzymes
hydrolyzed stevioside and generated rubusoside, but substrate
specificity analysis indicated that GH3-2 is the most suitable choice
for the durative, steady, and high-efficiency production of rubusoside

Coronaviruses (CoVs) are a large family of viruses responsible for the
severe ill effects on human health. The most severe outbreak includes
Severe Acute Respiratory Syndrome (SARS-CoV), Middle East Respiratory
Syndrome (MERS-CoV) and Coronavirus disease 2019 (COVID-19) caused by
Severe Acute Respiratory Syndrome coronavirus 2 (SARS-CoV-2). The
COVID-19 poses major challenges to clinical management because no
specific FDA-approved therapy yet to be available. Thus, the existing
therapies are being used for the treatment of COVID-19, which are under
clinical trials and compassionate use, based on in vitro and in silico
studies. In this review, we summarized the potential therapies like
small molecules, bioactive compounds, nucleoside and nucleotide analogs,
peptides, antibodies, natural products, and synthetic compounds
targeting the complex molecular interactions involved in COVID-19. In
this review＞230 natural and chemically synthesized drug therapies were
described with their recent advances in research and development being
done in terms of their chemical, structural and functional properties.
Further, provided insights on possible targets for viral cells, viral
proteins, viral replication, and different molecular pathways for the
discovery of novel viral- and host-based therapeutic targets against
SARS-CoV-2.
Assessing the effects of Sunlight on the Photooxidation of Tropical Oils
Authors: Dodoo Daniel , Tulashie Samuel , Dodoo Thomas , Kwaw Francis

This study aims to investigate the influence of sunlight on the
photooxidation of tropical oils (TOs). Coconut oil (CNO), palm oil (PO),
and palm kernel oil (PKO) were chosen for determining the indicators of
photooxidation when exposed to and in the absence of sunlight for seven
weeks. The results showed a significant (p < 0.05) increase in
free fatty acid (FFA) levels and peroxide value (PV) when the TOs were
exposed to sunlight. The iodine value (IV) and colour content decreased
significantly (p < 0.05) due to the decomposition of
unsaturated FFAs owing to the breaking-down of the π-bonds and the
degradation of colour pigments during photooxidation. FTIR analysis
showed strong vibrational absorptions at 1721 and 3505
cm, 1720 and 3560 cm, and 1721
and 3554 cm for the CNO, PO, and PKO samples exposed
to sunlight, respectively. These bands can be attributed to the presence
of secondary oxidation products, which were absent in the TOs that were
not exposed to sunlight. A simulation was performed to support the FTIR
results, which also indicated peaks from the secondary oxidation
products at 1744 and 3660 cm. The study also
revealed that the rate of photooxidation was different for each TOs. The
rate of oxidation followed the order PO > PKO
> CNO. In contrast, no notable changes were observed in the
TOs kept away from the sunlight. These results suggest that exposing TOs
to sunlight influences their oxidation stability and quality.

This study was aimed to investigate the roles of income and other socioeconomic variables such as household size, land size, head of household education level, raising the animals, source of income on food demand in rural Burundi. The demands for food and nutrients among the households in rural Burundi were examined using a recent survey done by the authors. An almost ideal demand system (AIDS) was employed to estimate the price and expenditure elasticities and the impact of socioeconomic variables on food demand patterns. An econometric model was then used to analyze the determinants of food demand. The estimated expenditure elasticities for the food groups range from 0.64 for oils to 1.36 for meats. These outcomes showed that there is a higher expenditure elasticities for meats, fish, and animal products, as well as cereals and grains. The results showed that the income and other socioeconomic variables exerted significant effects on food demand. The income and other socioeconomic variables exerted a significant impact on the food demand, and higher expenditure elasticity for food group items will increase remarkably with rising income.

"Through a Möbius transformation, we study aspects like topology, ligth cones, horizons, curvature singularity, lines of constant Schwarzschild coordinates r and t, null geodesics, and transformed metric, of the spacetime (SKS/2)^' that results from: i) the antipode identification in the Schwarzschild-Kruskal-Szekeres (SKS) spacetime, and ii) the suppression of the consequent conical singularity. In particular, one obtains a non simply-connected topology: (SKS/2)^' = R^2* ×S^2 and, as expected, bending light cones."
Double-layer affective visual question answering network

Visual Question Answering (VQA) has attracted much attention recently in both natural language processing and computer vision communities, as it offers insight into the relationships between two relevant sources of information. Tremendous advances are seen in the field of VQA due to the success of deep learning. Based upon advances and improvements, the Affective Visual Question Answering Network (AVQAN) enriches the understanding and analysis of VQA models by making use of the emotional information contained in the images to produce sensitive answers, while maintaining the same level of accuracy as ordinary VQA baseline models. It is a reasonably new task to integrate the emotional information contained in the images into VQA. However, it is challenging to separate questionguided-attention from mood-guided-attention due to the concatenation of the question words and the mood labels in AVQAN. Also, it is believed that this type of concatenation is harmful to the performance of the model. To mitigate such an effect, we propose the Double-Layer Affective Visual Question Answering Network (DAVQAN) that divides the task of generating emotional answers in VQA into two simpler subtasks: the generation of non-emotional responses and the production of mood labels, and two independent layers are utilized to tackle these subtasks. Comparative experimentation conducted on a preprocessed dataset to performance comparison shows that the overall performance of DAVQAN is 7.6% higher than AVQAN, demonstrating the effectiveness of the proposed model.We also introduce more advanced word embedding method and more fine-grained image feature extractor into AVQAN and DAVQAN to further improve their performance and obtain better results than their original models, which proves that VQA integrated with affective computing can improve the performance of the whole model by improving these two modules just like the general VQA.
TrustRec: An effective approach to exploit implicit trust and distrust relationships along with explicitones for accurate recommendations

Published: November 2020

Trust-aware recommendation approaches are widely used to mitigate the cold-start problem in recommender systems by utilizing trust networks. In this paper, we point out the problems of existing trust-aware recommendation approaches as follows: (P1) exploiting sparse explicit trust and distrust relationships; (P2) considering a misleading assumption that a user pair having a trust/distrust relationship certainly has a similar/dissimilar preference in practice; (P3) employing the transitivity of distrust relationships. Then, we propose TrustRec, a novel approach based on the matrix factorization that provides an effective solution to each of the aforementioned problems and incorporates all of them in a single matrix factorization model. Furthermore, TrustRec exploits only top-k most similar trustees and dissimilar distrustees of each user to improve both the computational cost and accuracy. The results of our extensive experiments demonstrate that TructRec outperforms existing approaches in terms of both effectiveness and efficiency.
End-to-end diagnosis of cloud systems against intermittent faults
Authors: Wang Chao , Fu Zhongchuan , Huo Yanyan
Published: November 2020

The diagnosis of intermittent faults is challenging because of their random manifestation due to intricate mechanisms. Conventional diagnosis methods are no longer effective for these faults, especially for hierachical environment, such as cloud computing. This paper proposes a fault diagnosis method that can effectively identify and locate intermittent faults originating from (but not limited to) processors in the cloud computing environment. The method is end-to-end in that it does not rely on artificial feature extraction for applied scenarios, making it more generalizable than conventional neural network-based methods. It can be implemented with no additional fault detection mechanisms, and is realized by software with almost zero hardware cost. The proposed method shows a higher fault diagnosis accuracy than BP network, reaching 97.98% with low latency.
Fractures of the acetabulum - surgical treatment and complications
Authors: Milenkovic Sasa , Mitkovic Milan , Mitkovic Milorad , Stojiljkovic Predrag
Published: November 2020

Acetabular fractures represent severe injuries that mostly occur in car accidents, or after falling from greater heights, most often in the working male population. Acetabular fractures are present in our clinical practice and their treatment requires good education and surgical training. Surgical experience is one of the prerequisites for achieving good treatment results, since these fractures are accompanied by numerous complications. In order to acquire knowledge and skills in this field of surgery, it is necessary to have a national center for education at one of the medical faculties in Serbia. All dislocated acetabular fractures (? 2 mm) require early surgery, anatomical reduction, and stable internal fixation of acetabular fracture. Acetabular fracture-dislocation requires urgent reduction of the dislocated femoral head. The anatomic reduction of the fracture is related to the time of definitive bone fixation of the fracture. Fourteen days after the fracture, anatomic reduction is more difficult to achieve. In addition to the factors that positively affect the results of treatment, there are negative factors as well, which result in poor outcomes. They are directly correlated to the initial trauma that occurs at the time of injury. Fracture comminution, large dislocation (> 20 mm), injury of the femoral head, posterior dislocation of the hip, impaction, traumatic or iatrogenic sciatic nerve palsy ? these are all factors that negatively affect the outcome and are responsible for complications, as opposed to positive factors.
