Compressão de Dados Local em Tempo Real Energeticamente Eficiente para Redes WBAN
Authors: Passos Cainã , Pedroso Carlos , Batista Agnaldo , Nogueira Michele , Santos Aldri
Published: February 2021

A evolução das tecnologias sem fio tem permitido a criação de diversos tipos de redes para suportar os serviços do dia-a-dia das pessoas. Entre as redes voltadas ao monitoramento dos cuidados com a saúde, destacam-se as redes corporais sem fio (WBANs), que possibilitam um monitoramento contínuo e em tempo real dos dados fisiológicos. Contudo, este monitoramento acarreta uma excessiva transmissão de dados e eleva o consumo de energia dos dispositivos. Embora algumas abordagens reduzam o consumo de energia, poucas desconsideram a transmissão de informações redundantes. Este trabalho apresenta o mecanismo GROWN para gerenciar a redundância da informação através de compressão de dados fisiológicos em dispositivos vestíveis, reduzindo a transmissão de dados e o consumo de energia do dispositivo em WBANs de tempo real. O GROWN combina métodos de compressão de dados local com e sem perdas a partir de limiares definidos. Avaliação por experimentações do GROWN demonstrou uma diminuição do consumo de energia dos dispositivos em até 55,73%, o aumento do tempo de vida da rede e latência máxima de 55ms, comprovando sua eficiência e aplicação em WBANs de tempo real.
Caracterização de Funções Virtuais de Rede e Aplicação para Gerenciamento de Elasticidade de Serviços
Authors: Heideker Alexandre , Kamienski Carlos A.
Published: February 2021

A Virtualização de Funções de Rede (NFV) e o Encadeamento de Funções de Serviço (SFC) fornecem ferramentas essenciais para a ampla adoção da computação em nuvem, reduzindo o CAPEX e OPEX e possibilitando o gerenciamento autônomo e elástico de serviços. Tradicionalmente as métricas de CPU e Memória são utilizadas para promover a elasticidade, por vezes produzindo equívocos na avaliação da carga destes recursos. Este artigo caracteriza o comportamento de funções de rede e aplicação virtualizadas, explorando novas métricas em experimentos com Firewall, DPI, Proxy, servidor Web e Context Broker de IoT, assim como suas respectivas composições em SFC. Os resultados obtidos mostram que a avaliação das filas TCP permitem uma melhor compreensão do comportamento destas funções, identificando claramente não só o estado atual como a tendência de seu comportamento diante do crescimento no tráfego.
Uma Avaliação sobre a Tolerância a Falhas no Plano de Dados em Controladores SDN
Authors: Ruchel Lucas V. , Turchetti Rogério C. , de Camargo Edson T.
Published: February 2021

Redes Definidas por Software fazem do controlador o seu elemento central. Portanto, é fundamental que o controlador apresente funcionalidades que, além de melhorar o desempenho global da rede, assegurem a continuidade dos serviços perante falhas. OpenDayLight (ODL) e o Open Network Operating System (ONOS) são dois importantes controladores de código aberto e com plano de controle distribuído. Este trabalho avalia a tolerância a falhas no plano de dados dos controladores ODL e ONOS considerando diversos cenários de falhas. Os experimentos consideram falhas e recuperações de links e switches, com diferentes fluxos tanto no modo reativo quanto proativo. Os resultados experimentais exibem o tempo que os controladores levam para detectar as falhas, direcionar o tráfego para caminhos redundantes e identificar o retorno dos links e switches.
A Dashboard for System Trustworthiness Properties Evaluation
Authors: Camargo Diego , Gaia Felipe Nunes , Basso Tania , Moraes Regina Lúcia de Oliveira
Published: February 2021

Understanding the trustworthiness of a cloud system is a difficult task, because it encompasses a large diversity of properties such as security, privacy, performance, among others. Evaluating and improving the system regarding trustworthiness require the analysis of huge data considering their historical status. The goal of this paper is to present a dashboard developed for the visualization of these properties, the relationship among them and their relevance in the composition of a trustworthiness score over usage time.
Die sicherheitspolitische Community in Deutschland
Authors: Stöhr Florian
Published: February 2021

German politicians and people working in the media often mention the so-called security community when referring to experts working in the field of security politics. The term is not defined, however. The security community is not systematically researched. Who are the main actors of German security policy? What are their backgrounds, functions and activities? This thesis identifies a broad security landscape and a well-connected network of political, academic and social leaders. Based on extensive empirical data, expert interviews and case studies the thesis closes a research gap. It offers many practical and fundamental results for professionals and points out questions for further research about the security community in Germany.
Über die Gestaltung der Energiewende auf Landesebene
Authors: Sabel Michael Maximilian
Published: February 2021

The Energiewende is the central challenge for politics, business and society in the 21st century. It takes place throughout the multi-level system, at the supranational, national and subnational levels. This dissertation focuses on the subnational level that has so far been less researched. The opportunities and challenges for shaping own energy and climate protection policies are examined using the example of North Rhine-Westphalia, taking into account the vertical and horizontal political interdependence. The North Rhine-Westphalian Climate Protection Law of 2013 and the North Rhine-Westphalian Climate Protection Plan of 2015 form the central research subjects.
Gesundheit und Motivation in der Pflegeausbildung
Authors: Grothe Frank
Published: February 2021

The book deals with health-promoting and health-endangering behaviours and experiences in coping with training and work demands in nursing training. It uncovers personality specific resources and requirements in the form of inner attitudes and by taking a closer look at motivation. The AVEM manual and a questionnaire on motivation during training are used for this purpose. The results of the survey can be used to derive possible changes and alternative courses of action which can already contribute to a healthy and motivated professional future in nursing during training.
People Used To Die Every Day
Authors: Baker Chad ,   After Dinner Conversation
Published: February 2021

If sleep, and the dreams that come with them, were no longer required, would you still do it? Would humanity be different if we didn’t have the time to imagine what might be? Would you break the law to support the dream habits of your partner? In this work of philosophical short story fiction, Peter finds out his partner Samir has been sneaking around behind his back to “try out dreaming.” According to Samir, he likes the way sleeping, and dreaming, makes him feel. And besides, he argues, it doesn’t do any harm; his work will never find out. Peter decides to break the law in support of their relationship and to stop taking the drug that makes sleep and dreams unnecessary, in order to better understand his partner. However, after a nightmare, Peter decides that sleep and dreaming isn’t for him and the government is right.
Development and Testing of Thrombolytics in Stroke
Authors: Nikitin Dmitri , Choi Seungbum , Mican Jan , Toul Martin , Ryu Wi-Sun , Damborsky Jiri , Mikulik Robert , Kim Dong-Eog
Published: February 2021

Despite recent advances in recanalization therapy, mechanical thrombectomy will never be a treatment for every ischemic stroke because access to mechanical thrombectomy is still limited in many countries. Moreover, many ischemic strokes are caused by occlusion of cerebral arteries that cannot be reached by intra-arterial catheters. Reperfusion using thrombolytic agents will therefore remain an important therapy for hyperacute ischemic stroke. However, thrombolytic drugs have shown limited efficacy and notable hemorrhagic complication rates, leaving room for improvement. A comprehensive understanding of basic and clinical research pipelines as well as the current status of thrombolytic therapy will help facilitate the development of new thrombolytics. Compared with alteplase, an ideal thrombolytic agent is expected to provide faster reperfusion in more patients; prevent re-occlusions; have higher fibrin specificity for selective activation of clot-bound plasminogen to decrease bleeding complications; be retained in the blood for a longer time to minimize dosage and allow administration as a single bolus; be more resistant to inhibitors; and be less antigenic for repetitive usage. Here, we review the currently available thrombolytics, strategies for the development of new clot-dissolving substances, and the assessment of thrombolytic efficacies in vitro and in vivo.
Selection of the preferred design for manufacturability by constructing the Pareto tuple
Authors: Irzaev Gamid , Kanaev Magomedimin , Isalova Marzhanat
Published: February 2021

The system to ensure manufacturability of industrial products is aimed at reducing the costs of all types of resources at the stages of their life cycle, selecting the most competitive in cost and functionality designs at the early stages of engineering. When assessing the new designs for manufacturability to be developed and selecting the best analogue or basic reference standard in terms of manufacturability, the engineer faces the need to apply multicriteria optimization methods. The solution of the applied task of design optimization by quantitative criteria of manufacturability in the conditions of an uncertain design and production environment is considered in the article as implementable in the system for ensuring design for manufacturability. The decisive rules for implementing the multi-step process of ranking the design options according to the manufacturability criteria with the construction of the Pareto tuple are formed. The implementation of the method is exemplified in practice when choosing the oscilloscope design that is advantageous in terms of manufacturability at a mass-production instrument-making plant.
La fenomenología dialéctica de Eduardo Nicol
Authors: Cortés Sánchez Francisco José
Published: February 2021

El presente trabajo tiene la finalidad de mostrar la fenomenología dialéctica de Eduardo Nicol. Para ello parto de lo que considera Nicol el origen de la crisis de la metafísica. Identificado el origen de tal crisis, expondré los tipos de relación del conocimiento que existen en relación a lo que Nicol llama “ontología de la verdad”. En esta exposición, mostraré el sentido que adquiere para Nicol el carácter apodícti-co de la experiencia y la relación existente entre método y ontología. Estas dos ideas nos revelarán la importancia que tiene el “otro” en el desarrollo fenomenológico nicoliano así como el sentido de la historicidad.Como consecuencia, la fenomenología dialéctica se presenta como un método que pretende dar solución a la crisis de la metafísica continuando la tradición fenomenológica iniciada por Husserl a través de una revisión de la misma.This research is intended to show the phenomenological method of Eduardo Nicol. To do this I start from the consideration of Nicol regarding the origin of the crisis of metaphysics. Identified the origin of this crisis, I will explain the relationship types of knowledge that exist in relation to what Nicol called "ontology of truth." In this presentation, I will show the meaning that for Nicol has the apodictic character of experience and the relationship between method and ontology. These two ideas will reveal the importance of the "other" in the phenomenological development and sense of historicity. As a result, dialectical phenomenology is presented as a method that aims to answer the crisis of metaphysics continuing the tradition begun by Husserl through a review of it.
Sobre el fenomenologizar como cinestesia concretizante
Authors: Posada Varela Pablo
Published: February 2021

Nos proponemos, en este artículo, sentar las bases necesarias para investigar la correlación entre algunas formas de epojé y las reducciones a las que dichas suspensiones abren, y que corresponden a una concreción cada vez más rica. Nuestra aproximación de la concreción fenomenológica se apoya, abiertamente, en la mereología (i.e. se atiene a los estrictos términos de la IIIª Investigación Lógica). Tras un breve repaso de algunos conceptos mereológicos aplicados al giro transcendental de la fenomenología, trataremos de apresar, mereológicamente, la especificidad de la problemática finkeana en su VIª Meditación Cartesiana. Habremos pues de diseccionar las partes de la correlación transcendental cruzándolas con el particular lugar que, en esa concreción (i.e. de la correlación transcendental), ocupa esa “parte” no concrescente (sino indirectamente concretizante) que es el yo fenomenologizante. Ella conformará la “parte” antecedente del “todo” (en sentido lato) de la cinestesia fenomenologizante que tratamos de elucidar, y cuyo consecuente será el todo (ahora sí en sentido estricto) de la correlación transcendental. Intentamos así contribuir al esclarecimiento del proceso de reducción fenomenológica, sentando las bases para una investigación sobre las articulaciones concretas entre epojé y reducción.The aim of this paper is to lay the ground for understanding the correlation between some forms of epochè and the reduction they open to, which corresponds, each time, to a richer type of concreteness. Our approach of phenomenological concreteness is mereological (i.e. within the very terms of the 3rd Logical Investigation). Therefore, after remembering some basic concepts of the husserlian mereology and their possible use within transcendental phenomenology, we try to grasp the specificity of the questions posed by Eugen Fink in his 6 th Cartesian Meditation. We shall expose the parts of the transcendental correlation and then account for the particular role played, “within” this concretion (i.e. that of the transcendental correlation), by this particular “part” which is the phenomenologizing ego (if not concrescent, yet indirectly concretizing). The phenomenologizing ego will be the antecedent “part” or term within this “whole” (lato sensu) consisting on the phenomenologizing kinesthesis. Thereafter, the consequent term of such a kinesthesis corresponds to the whole (this time stricto sensu) of the transcendental correlation. We thus intend to throw some light on the process of phenomenological reduction and set the basis for further investigations regarding the concrete articulation between epochè and reduction.

Charles Taylor: de la Antropología filosófica a la Filosofía práctica
Authors: Rodríguez García Sonia E.
Published: February 2021

Charles Taylor es comúnmente identificado como uno de los padres fundadores del comunitarismo teórico, pero tal identificación no da cuenta de la amplitud del pensamiento del filósofo canadiense. A través de este trabajo de investigación pretendemos articular la filosofía de Taylor partiendo del proyecto filosófico que explícitamente inicia en sus primeros trabajos, a saber, la configuración de una antropología filosófica, a través de la cual abordaremos los grandes temas que han ocupado su vida -ética, política y religión- en la puesta en marcha de una filosofía con intenciones puramente prácticas.Charles Taylor is commonly identified as one of the founding fathers of theoretical communitarianism, but such identification does not realize the extent of his thinking. Through this research, we try to articulate the Taylor's philosophy from his philosophical project, that he explicitly started in his early work, namely, the configuration of a philosophical anthropology, through which we will address the major issues that have occupied his life - ethics, politics and religion- in the implementation of a philosophy with purely practical intentions.
Para além do quadro: intersecções entre o trabalho de Tadeusz Kantor e o pensamento de Aby Warburg
Authors: Farias Igor Gomes , Moretti Maria de Fátima de Souza , Wilbert Gedoz Laura
Published: February 2021

Este artigo buscou identificar os cruzamentos entre o trabalho artístico de Tadeusz Kantor e o pensamento de Aby Warburg. A partir de uma análise da obra kantoriana, influenciada por sua relação com as artes plásticas, foi ressaltado seus evidentes pontos de aproximação com a lógica por trás do Atlas Mnemosyne. Reconhecendo a imagem como o ponto central dos paralelos enfatizados aqui, refletiu-se sobre como os ensinamentos de Warburg contribuem para a leitura de obras artísticas posteriores a ele. Deste modo, destacou-se o método da montagem e de associação de imagens, bem como as importantes relações empregadas por Didi-Huberman ao retomar Warburg nas discussões contemporâneas da história da arte.
Design de moda: ensino e regimes de interação
Authors: Chen Luciana
Published: February 2021

Esse artigo se debruça sobre os regimes de interação nas disciplinas voltadas às produções visuais, verbo-visuais e audiovisuais no curso de Design de Moda do Centro Universitário Senac – Santo Amaro. Investiga como os regimes de interação por acidente e por ajustamento podem contribuir para o ensino. Ao adentrar no campo da educação, nos conduzimos para uma orientação construtivista, que promove a aproximação de conteúdos às realidades dos estudantes e, posicionamentos críticos e de ruptura. Para tal, recorremos a conceitos tais como: presença, identidade/alteridade, existência, acaso, potencialidade. As reflexões são alicerçadas na semiótica discursiva desenvolvida por Algirdas Julien Greimas e desdobradas por Eric Landowski e Ana Claudia Mei Alves de Oliveira e, nos educadores Paulo Freire e Fayga Ostrower. A investigação aponta: os regimes de interação que se dão no ensino do recorte proposto, podem se estender a outras disciplinas e cursos; o ensino de cunho construtivista propicia o surgimento de trabalhos inovadores, enquanto o ensino autoritário favorece a cópia de trabalhos, estando atrelado à tradição; a necessidade de docentes conjugarem o inteligível e o sensível para que o ensino e o aprendizado sejam significativos.
Subversão em performance na escola pública e diálogos com as políticas culturais
Authors: Teixeira Thiago Camacho
Published: February 2021

Neste artigo, busquei relações entre a subversão em artes, na transgressão como elemento da performance, com aspectos das economias locais em cultura, no espaço da escola pública, onde sou professor. No percurso de meu doutorado, construo paralelos com alguns conceitos de política cultural no sistema econômico e político vigente, chamando a atenção crítica para a arte formatada nos ambientes de educação apenas como um produto restrito a dissimular ausências e carências, a falta de acesso às ampliações de percepções estéticas, que evocam para mim um embate contra a simples reprodutibilidade de sistemas artísticos. Benhamou, no texto A economia da cultura, fala em política cultural e pública de forma que estas possam construir pontes entre a arte, tomada como uma imanência completa e total do indivíduo e sua idiossincrasia – utopias pessoais, realidades internas, ontológicas e subjetivas –, e o sistema do qual o mercado faz parte, com seus efeitos monopolistas. Desse modo, podemos mostrar um pouco sobre como estabelecer essas relações entre arte crítica subversiva, de confronto ideológico, moral, institucional, burocrático, com as políticas culturais que podem revitalizar espaços, gerar economias locais, sociais, e a geração de receitas em contato com o aspecto de mercado, sem que este absorva totalmente o ato criativo, transformandoo num produto sem história, sem vida, “sem alma”, a não ser que esse seja o objetivo da produção artística em questão.
O editorial de moda a partir da arte relacional
Authors: Coimbra Vanilson Luis de Melo , Mathias Jose Ronaldo
Published: February 2021

A pesquisa estuda o editorial de moda como narrativa fotográfica e analisa os conceitos de arte relacional, comparando no tempo o posicionamento e a liberdade criativa das editorias de moda com os seus colaboradores. Cada vez mais a arte vem construindo um campo que valoriza a imagem como o lugar das experiências, no qual o espectador é convidado a ser participante da obra e a assumir a mesma importância do artista. A obra só é completa com o fruto dessa relação. Os autores estudados são Nicolas Bourriaud, Anne Cauquelin e Vilém Flusser. Faz uso da pesquisa descritiva com foco nos editoriais de moda, onde observa-se a relação das editorias, dos colaboradores e de seus espectadores. Por fim, busca-se compreender de que maneira um editorial de moda, fruto do diálogo entre a inspiração e as relações compartilhadas durante o processo artístico, pode ser considerado uma forma relacional.
Moda e consumo periférico: a construção de identidade social a partir das ações promovidas pelo projeto ‘periferia inventando moda’ na cidade de São Paulo
Authors: Moura Danilo Souza , Campos Anderson Gurgel
Published: February 2021

Este estudo analisa como a moda está atrelada à construção de identidade social e cultural nas periferias de São Paulo. Para isso, foi realizada uma revisão bibliográfica sobre sociedade, consumo e moda que permitiu definir como nosso objeto de pesquisa a instituição social Periferia Inventando Moda que, com ações educacionais e sociais, desenvolve importante papel junto ao comportamento de moda do jovem periférico. Ao analisar a atuação dessa entidade foi possível entender com mais clareza o consumo, mas também a produção de moda e sua relação com a promoção do sentido de pertencimento e ressignificação de um espaço geográfico reconhecido pela pobreza e falta de oportunidades.
Educação, semiótica e o espírito do tempo: uma metodologia para a formação profissional tecnológica superior no Brasil pós-pandêmico
Authors: Marroni Fabiane , Ciaco João Batista
Published: February 2021

Este artigo tem por objetivo compreender e analisar, de forma breve, os desafios enfrentados pela educação no Brasil neste atual momento pandêmico. A proposta é trabalhar caminhos metodológicos que possam endereçar tais desafios frente às questões tecnológicas que a educação, em ambientes digitais, cria e estabelece, tanto para os professores quanto para os alunos e, eventualmente, suas famílias. As novas formas de interação, professor-aluno-tecnologia, devem seguir em direção a uma metodologia minimamente consistente para enfrentar as adversidades oriundas do espírito do tempo, com reflexos, também, na educação tecnológica superior. Assim pensando, estabeleceu-se, como base, o diálogo entre a Pedagogia da Autonomia, do educador Paulo Freire, defensor de uma pedagogia fundada na ética, no respeito, na dignidade e na autonomia do educando, e os regimes de interação – e mesmo de sentido – da sociossemiótica de Eric Landowski, procurando compreender as novas práticas do ensino que se estabelecem, às vezes, na presença mediada de professor e aluno, outras em presenças virtualizadas, de maneira assíncrona, em um caminho que, neste instante, coloca-se como necessário. Assim, torna-se imprescindível promover ações de inclusão social para a transformação e respeito pela coletividade, neste momento singular. Com essa finalidade, surgiu o Instituto OFÉ, criado para proporcionar educação profissional tecnológica superior, alicerçada na inovação e na justiça social, de forma a promover o desenvolvimento local e regional por meio de metodologia humana, sensível e acolhedora, valorizando o percurso do sujeito a partir de um ensino híbrido com acolhimento, que será apresentado neste trabalho.

La verificación de datos en Europa. Análisis de 5 iniciativas europeas: Maldita.es, Newtral, Pagella Politica, Les Décodeurs y BBC Reality Check
Authors: García Vivero Gloria , López Xosé
Published: February 2021

El presente texto pretende realizar una fotografía de cuál es la situación actual de la verificación en Europa mediante el estudio de varios fact-checkers europeos. Con el estallido de la pandemia del coronavirus, también se ha estudiado como ha afectado esta a la labor de los verificadores. Para ello se procede a realizar un análisis de contenido de las informaciones que publican, intentando encontrar semejanzas entre las iniciativas y buscando comprender la naturaleza y características de la desinformación con la que trabajan. Además, entrevistas con profesionales de los verificadores y con especialistas en fact-checking permitirán comprender sus rutinas, metodologías, y sus estructuras empresariales, intentando de nuevo establecer convergencias en el escenario europeo. También se intentará ver como ha repercutido la crisis de desinformación causada por el coronavirus en estos medios. Al final encontramos una actividad constante y similitudes en los contenidos y metodologías. Las redes sociales (58% de los contenidos) y la política (68% de piezas) como principales vías y temáticas para la desinformación en Europa. El fact-checking como una salida factible para los periodistas, aunque no reporta grandes beneficios para las empresas. Por último, la crisis sanitaria del coronavirus ha supuesto un aumento del trabajo de estas iniciativas (en la mayoría de los casos un aumento del doble de piezas publicadas).
¿Quién cree las fake news? Análisis de la relación entre consumo de medios y la percepción de veracidad de noticias falsas sobre la enfermedad COVID-19 en Nuevo León, Méxic
Authors: Galarza Molina Rocío
Published: February 2021

Este estudio, que presenta los resultados de una encuesta en línea aplicada a la población del estado de Nuevo León, México (n=743), aporta un retrato de características individuales y hábitos de consumo de información que están relacionados con la creencia de fake news sobre la enfermedad COVID-19. Se encontraron relaciones entre la edad (asociación positiva) y nivel educativo (asociación negativa) y la proclividad a creer en noticias falsas, lo cual acentúa la necesidad de extender esfuerzos de alfabetización mediática. Asimismo, los resultados indican que quienes consumen con más frecuencia noticias en periódicos impresos o en línea y en Internet son menos propensos a creer en fake news sobre la enfermedad, lo cual se alinea con la escuela de pensamiento sobre efectos de medios de comunicación –la teoría de movilización– que destaca una influencia positiva de estos en la sociedad. En cambio, en los hallazgos se observa que el mayor uso de YouTube para informarse —y no otras redes sociales como suele pensarse— es un factor vinculado positivamente con la creencia de noticias falsas sobre COVID-19, por lo que se debe poner especial atención a acciones tomadas para combatir desinformación en ese espacio.
Participación ciudadana en la creación de contenidos como herramienta de fidelización y consenso
Authors: Blázquez Rosales Isaías
Published: February 2021

Los medios de comunicación públicos están profundizando en la colaboración para la creación de contenidos junto a los usuarios. Este elemento de participación social moldea la relación con la ciudadanía, en un contexto de acelerados cambios tecnológicos, financieros y sociales. A raíz del surgimiento de las redes sociales tal y como las entendemos hoy en día y de plataformas como YouTube, la respuesta de los ciudadanos fue inmediata y masiva a favor de la creación y difusión de contenidos propios. Las radiotelevisiones públicas han lanzado proyectos de creación compartida en entornos digitales que generan experiencias transmedia, mediante las que los contenidos se desarrollan en varios espacios y en las que la participación de los usuarios es esencial. El proceso colaborativo entre medios y ciudadanos permite fidelizar a los usuarios: incrementar su nivel de compromiso con el servicio público. Un ciudadano al que se escucha, con el que se conversa y que genera contenido es un activo para la sociedad a la que pertenece. El contenido sigue siendo el principal valor en el sector de los medios de comunicación y del consumo audiovisual. Si no es de calidad, por ejemplo si deforma los hechos, puede tener graves efectos en la sociedad. Uno de los principales riesgos es la quiebra del consenso sobre los hechos por una eventual pérdida de confianza en las voces autorizadas. Es el reto de los medios de comunicación públicos: crear un entorno de participación ciudadana en el que se mantenga o, incluso, se aumente la confianza de la ciudadanía.
Citizen Participation in Public Service Media: What It Really Means
Authors: Dragomir Marius
Published: February 2021

In a converged media system where the public is more than ever in control of what, when and where to consume content, public service media must put citizen participation at the heart of their strategies. That means giving the audiences more control over funding of public media, increased participation of civil society in the governance of these media outlets and more meaningful involvement of citizens in their content production process. This paper summarizes recent trends in how media companies in general engage with their audiences in the digital economy and explores opportunities and models of citizen participation in the public media of the future. The paper argues that without adjusting to the realities of the digital economy, which would mean first and foremost building audience centric networked platforms of content distribution, public service media will have a hard time to attract new followers, especially among younger audiences, and risk alienating their already declining audiences. In a media ecosystem populated by a growing number of content producers that are all fiercely competing to capture people’s attention, public service media can gain a competitive edge only if they engage citizens in innovative, meaningful ways. Without the citizen participation element, they risk becoming a marginal player or, worse, a thing of the past.

En recherche de réponses nouvelles pour satisfaire des besoins sociaux majeurs, l’Etat français teste actuellement une forme innovante de contrat public-privé inspirée des Social Impact Bonds : les Contrats à Impact Social (CIS). Notre article examine les ressorts de la création des CIS en France et les conséquences potentielles des choix gouvernementaux. Notre étude montre l’influence puissante du contexte théorique et idéologique international sur la détermination de nouveaux instruments d’action publique. Elle apporte ainsi un éclairage original sur les arbitrages effectués par les gouvernements français en faveur des CIS, comme sur les opportunités et les risques inhérents à ces choix.
Formation continue des bibliothécaires en France : état des lieux et prospective autour de l’éducation aux médias et à l’information
Authors: Barrio Amélie , Bourdet Julienne
Published: February 2021

L’offre de formation des bibliothécaires à l’éducation aux médias et à l’information (EMI) reste disparate en France et nécessite une réflexion sur la structuration et le maillage de l’offre globale sur cette thématique. À partir d’une analyse des actions de formation proposées par les réseaux des Centres régionaux de formation aux carrières des bibliothèques (CRFCB) et des Unités régionales de formation à l’information scientifique et technique (URFIST), des propositions peuvent être établies pour développer les programmes de formation ainsi que les compétences des bibliothécaires dans ce domaine. L’objectif est de mettre en lumière des parcours de formation et des actions innovantes afin de répondre le mieux possible aux besoins des bibliothécaires.

Published: February 2021

En este artículo se analizan las referencias textuales de La Celestina que evidencian tanto la existencia del elemento mágico en la obra como su importancia estructural. Para ello, se ofrecen nuevos datos en favor de la hipótesis del enamoramiento de Melibea como consecuencia del conjuro celestinesco y se realiza un análisis comparativo entre los dos amantes y la retórica del amor cortés para descartar la hipótesis del tiempo implícito y aportar una nueva interpretación del amor entre Calisto y Melibea.
Hacia un censo completo unificado de los ejemplares conservados de Celestina (I): ejemplares de ediciones en castellano localizables en línea
Authors: Saguar García Amaranta
Published: February 2021

En una época en la que las bibliotecas no dejan de volcar nuevos catálogos en la red y de actualizar los antiguos, en la que los catálogos colectivos regionales no dejan de sacar a la luz y de hacer accesibles colecciones que de otra manera pasarían desapercibidas para los investigadores, en la que los catálogos y metacatálogos digitales permiten consultar de una sola vez decenas de fondos repartidos por el mundo, el redescubrimiento de ejemplares de Celestina perdidos o no consignados hasta el momento no debería sorprender a nadie. Estas especiales circunstancias han hecho que mantener un censo completo y actualizado de ejemplares localizados de Celestina requiera la revisión periódica de dichos recursos digitales con el objetivo de incorporar nuevos ejemplares, corroborar la existencia de otros y corregir los posibles ejemplares fantasma de versiones anteriores. El presente trabajo quiere ofrecer un punto de partida para esta revisión periódica reuniendo por escrito y en un mismo lugar todos los ejemplares conservados de ediciones en castellano de Celestina anteriores a su prohibición inquisitorial localizables en línea a 1 de noviembre de 2020.

D. thesis focuses on the solvothermal synthesis of degenerate Ga3+ doped ZnO semiconductor nanocrystals and the study of the crystalline structure, electronic structure and morphology, as well as optical and magnetic properties of the obtained materials. The experimental part investigates ways to achieve a higher degree of doping and the concentration of free charge carriers, as well as their effect on localized surface plasmon resonance-induced light absorption in the infrared part or the light spectrum or transition metals (Fe3+, Ni2+, Mn2+) doped ZnO magnetization nature. Literature review summarises information through the period from 1954 to 2020, using the latest literature, which is available in internet databases. The review provides information on various nanocrystal synthesis methods used to form zinc oxide nanocrystals. Degenerate semiconductor metal oxides, their optical properties, as well as diluted magnetic oxide semiconductor nanocrystals are considered. The results describe various doped ZnO nanocrystal products that are synthesised by the solvothermal synthesis method and their optical, morphological and physical properties. The results of the research show the possibility to adjust the amount of gallium introduced into ZnO nanocrystals by controlling solvents and additives. The magnetic properties of ZnO nanocrystals co-doped with transition metals and gallium change depending on the amount of gallium introduced; by photodoping Ga-doped ZnO nanocrystals, it is possible to change the concentration of their free charge carriers.

Real-time systems must avoid hazardous situations. To achieve this, their functionality should be investigated under time constraints. In this paper, a modeling based on Hierarchical Communicating Real-time State Machine (H- CRSM) and analysis methodology is proposed to examine statically ANSI-C code to obtain the hazardous events in the input system. A hazardous event equation is taken as input to the proposed system. The output is a list of hazardous scenarios. A path in the code showing the cause of the undesirable event is associated with each hazardous scenario. The strength of the proposed methodology is that the process of hazardous situations detection does not require running the ANSI-C program multiple times with different input values. It also focuses on analyzing the software level of the life cycle. Most of the verification tools check the system level. The system level may be bug-free but the software level may not.

The number of subscribers in mobile networks is growing rapidly, which challenges the network management and data delivery. The efficient management and routing are key solutions. An important one of the solutions is the Distributed Mobility Management (DMM) that to handles the mobility of subscribers at the edge of mobile networks and load balancing. Otherwise, mobility anchors are distributed across the network, which can manage the handover procedures. In this paper, we propose a novel mobility anchor selection scheme based on the results of a cost function with three factors, to select a suitable cell and anchor for moving subscribers and improve the handover performances of the network. Our results illustrate that the proposed scheme provides significantly enhanced handover performance.

The ubiquitous presence of inhibitory interneurons in the thalamus of primates contrasts with the sparsity of interneurons reported in mice. Here, we identify a larger than expected complexity and distribution of interneurons across the mouse thalamus, where all thalamic interneurons can be traced back to two developmental programmes: one specified in the midbrain and the other in the forebrain. Interneurons migrate to functionally distinct thalamocortical nuclei depending on their origin: the abundant, midbrain-derived class populates the first and higher order sensory thalamus while the rarer, forebrain-generated class is restricted to some higher order associative regions. We also observe that markers for the midbrain-born class are abundantly expressed throughout the thalamus of the New World monkey marmoset. These data therefore reveal that, despite the broad variability in interneuron density across mammalian species, the blueprint of the ontogenetic organisation of thalamic interneurons of larger-brained mammals exists and can be studied in mice.

The developmental origins and evolutionary histories of cell types, tissues, and organs contribute to the ways in which their dysfunction produces disease. In mammals, the nature, development and evolution of maternal-fetal interactions likely influence diseases of pregnancy. Here we show genes that evolved expression at the maternal-fetal interface in Eutherian mammals play essential roles in the evolution of pregnancy and are associated with immunological disorders and preterm birth. Among these genes is HAND2, a transcription factor that suppresses estrogen signaling, a Eutherian innovation allowing blastocyst implantation. We found dynamic HAND2 expression in the decidua throughout the menstrual cycle and pregnancy, gradually decreasing to a low at term. HAND2 regulates a distinct set of genes in endometrial stromal fibroblasts including IL15, a cytokine also exhibiting dynamic expression throughout the menstrual cycle and gestation, promoting migration of natural killer cells and extravillous cytotrophoblasts. We demonstrate that HAND2 promoter loops to an enhancer containing SNPs implicated in birth weight and gestation length regulation. Collectively, these data connect HAND2 expression at the maternal-fetal interface with evolution of implantation and gestational regulation, and preterm birth.

The origin recognition complex (ORC) cooperates with CDC6, MCM2-7, and CDT1 to form pre-RC complexes at origins of DNA replication. Here, using tiling-sgRNA CRISPR screens, we report that each subunit of ORC and CDC6 is essential in human cells. Using an auxin-inducible degradation system, we created stable cell lines capable of ablating ORC2 rapidly, revealing multiple cell division cycle phenotypes. The primary defects in the absence of ORC2 were cells encountering difficulty in initiating DNA replication or progressing through the cell division cycle due to reduced MCM2-7 loading onto chromatin in G1 phase. The nuclei of ORC2-deficient cells were also large, with decompacted heterochromatin. Some ORC2-deficient cells that completed DNA replication entered into, but never exited mitosis. ORC1 knockout cells also demonstrated extremely slow cell proliferation and abnormal cell and nuclear morphology. Thus, ORC proteins and CDC6 are indispensable for normal cellular proliferation and contribute to nuclear organization.
The genetic landscape for amyloid beta fibril nucleation accurately discriminates familial Alzheimer’s disease mutations

Published: February 2021

Plaques of the amyloid beta (Aß) peptide are a pathological hallmark of Alzheimer’s disease (AD), the most common form of dementia. Mutations in Aß also cause familial forms of AD (fAD). Here, we use deep mutational scanning to quantify the effects of >14,000 mutations on the aggregation of Aß. The resulting genetic landscape reveals mechanistic insights into fibril nucleation, including the importance of charge and gatekeeper residues in the disordered region outside of the amyloid core in preventing nucleation. Strikingly, unlike computational predictors and previous measurements, the empirical nucleation scores accurately identify all known dominant fAD mutations in Aß, genetically validating that the mechanism of nucleation in a cell-based assay is likely to be very similar to the mechanism that causes the human disease. These results provide the first comprehensive atlas of how mutations alter the formation of any amyloid fibril and a resource for the interpretation of genetic variation in Aß.
