In the early 21st century, governments developed national broadband plans to supply high-speed broadband networks for the emerging digital economy and to enable digital services delivery. Most national broadband plans are now focused on moving to ever faster networks, but there is a growing need to develop national digital communications strategies to focus on the demand-side of the broadband “eco-system”. In this paper, we outline the approaches adopted by the United States, Canada, the United Kingdom, Singapore, and Korea to assist in the development (or renewal) of Australia’s national broadband strategy, or, as we prefer, national digital communications strategy. The paper draws on the lessons learned from the case-study countries and the recent pandemic and considers some theoretical aspects of the broadband ecosystem. We conclude by suggesting a process to re-evaluate Australia’s national digital communications strategy as it rolls forward, and to incorporate recent international trends to develop demand-side policies to enable greater adoption and use of existing broadband infrastructure and digital services.

Full textAbstract:
Canadian visual resources professionals believe a national strategy would raise the profile of their group who, although well known elsewhere, are not well known in Canada. Technology has made networking to share cataloguing and participation in electronic communications feasible, but many libraries do not have access to national utilities. Although digital capture and interactive electronic image storage and retrieval hold great promise for visual resources, there is a need for funding for retrospective conversion, imaging and the like. Networking makes authority work more important than it has been: a national strategy should include the formulation of a Canadian artist authority tool. Canadian iconography must be a component of any tools developed to describe art objects and their surrogates. In cooperation with CHIN Canadian art archivists and librarians must develop international standards for descriptive cataloguing. In addition, pressure must be brought to bear to end restrictive copyright for library users.

Full textAbstract:
COVID-19 has created significant changes in the everyday lives of teachers, children and parents. Due to school lockdowns in the spring semester of 2020, teachers shifted from in-person classroom teaching into “emergent remote teaching” (Hodges et al. 2020, para. 5), where digital tools and software were used for instruction and teacher-student communications. Many children have also shifted their social lives from face-to-face to virtual interactions (Hutchins 2020); for example, engaging in online family story reading, social media participation, and joining after school activities digitally. This pandemic has highlighted the importance of being literate in digital environments for children. Digital literacy, that is, literacy practices undertaken across multi-media, involving “accessing, using and analysing digital texts and artefacts in addition to their production and dissemination” (Sefton-Green et al. 2016, p. 15). The importance of the digital world and digital tools for the post-COVID future where digital literacy could become more prominently featured for teachers, children, and parents must not be underemphasized.
In this presentation, I reviewed the literature on young children’s digital literacy practices at home. Many studies have illustrated the benefits and various kinds of learning that children get from their digital play at home, including emergent literacy learning (Neumann 2016), digital citizenship (Bennett et al. 2016), etc. Moreover, I presented the complex trajectories of children playing with their digital devices and toys at home (Marsh 2017). In the 21st century children’s home play, the boundaries between the virtual and physical worlds are blurring (Marsh 2010; O’Mara and Laidlaw 2011; Carrington 2017).
More importantly, this literature review suggests a gap and an opportunity for future researchers to explore home digital literacy of children, who are from minority backgrounds in Canada, as literacy practices are socially and culturally situated. This presentation illustrates the importance of my proposed doctoral research, as my research aims to explore Culturally and Linguistically Diverse (CLD) children’s digital home literacy practices in Canada.

There has been a wealth of research in Latin America on the most recent global intensification of extractivism, or the capitalist exploitation of natural resources. Some of this research has examined the resistance among front-line Indigenous and rural communities, and allied environmental groups, who are challenging the development of mega-scale mining, oil, gas, monoagricultural, and related infrastructural projects. Researchers have noted many similar tactical repertoires that can take multiple forms (through direct action, media representation, and in legal, political, and educational forums) and extend across geographic scales (local, national, regional, and transnational). Communications is key to much of their work; however there has been far less research examining the communications practices in any detail. This article focuses on the communications practices in use in three Indigenous led campaigns against extractivist projects in North America, the decade-old Unist’ot’en Camp in northwestern Canada, Idle No More, and the #NoDAPL of the Standing Rock Sioux. My findings indicate that a resurgent Indigenous movement, in concert with environmental and other settler allies, has adopted an array of communications practices that combine protective action on behalf of their lands and waters with the creation of new communities in place-based assemblies and social media and digital networks.

Full textAbstract:
As the production, content and display of humanitarian images faced the requirements of digital media, humanitarian organizations struggled to keep equitable visual practices. Media specialists reflect on past and current uses of images in four Canadian agencies: the Canadian Red Cross, the Multicultural Council of Saskatchewan, the World University Service of Canada and IMPACT. Historically, the risk to reproduce the global inequalities they seek to remedy has compelled photographers, filmmakers and publicists in these agencies to develop codes of visual practice. In these conversations, they have shared the insights gained in transforming their work to accompany the rise of new digital technologies and social media. From one agency to the other, the lines of concern and of innovation converge. On the technical side, the officers speak of the advantage of telling personal stories, and of using short videos and infographics. On the organizational side, they have updated ways to develop skills in media production and visual literacy among workers, volunteers, partners and recipients, at all levels of their activity. These interviews further reveal that Communications Officers share with historians a wish to collect, preserve and tell past histories that acknowledge the role of all actors in the humanitarian sphere, as well as an immediate need to manage the abundance of visual documents with respect and method. To face these challenges, the five interviewees rely on democratic traditions of image-making: the trusted relationships, both with the Canadian public and with local peoples abroad, which have always informed the production and the content of visual assets. For this reason, humanitarian publicists might be in a privileged position to intervene in larger and urgent debates over the moral economy of the circulation of digital images in a globalized public space.

Over the previous decade, there has been a notable shift within sex work marketplaces, with many aspects of the work now facilitated via the internet. Many providers and clients are also no longer engaging in in-person negotiations, opting instead for communications via technological means, such as through mobile phones, email, and the internet. By analysing the qualitative interviews of indoor-based providers, clients, and agency managers, this paper addresses the occupational health and safety concerns that indoor sex workers experience in the digital age, as well as how technology use can both support and hinder their capacity to promote their health and safety. Using thematic analysis, we arrived at three salient and nuanced themes that pertain to the intersection of sex work, technology use, and occupational health and safety: screening; confidentiality, privacy, and disclosure; and malice. As socio-political context can affect the occupational health and safety concerns that providers experience, as well as their capacity to prevent or mitigate these concerns, we highlight our findings in light of prevailing societal stigma and a lack of legal recognition and protections for sex work in Canada.

Full textAbstract:
Cette thèse se penche sur les parcours et les pratiques d'artistes numériques naviguant au sein des secteurs multimédias de Montréal. L'étude des parcours de onze artistes numériques montréalais nous a permis de constater que leurs pratiques de production en arts numériques ne sont pas réductibles aux logiques de production propres à un seul lieu, que ce soit une entreprise privée, un centre d'art numérique ou encore l'université.
La question du maintien de ces pratiques amène à prêter attention aux pluralités des éléments qui informent leurs (re)constitutions perpétuelles, ce qui appelle de nouveaux modes de théorisation des parcours d'artistes numériques et de leurs pratiques. Nous proposons une nouvelle manière de penser ces parcours - en tant que trajectoires - pour mettre en valeur la pluralité des modes d'articulation de ces pratiques. Elles sont ainsi considérées du point de vue de leurs médiations coconstitutives avec différents éléments. Nous avons isolé trois ensembles d'éléments pour rendre compte du maintien des pratiques en arts numériques et au travers desquels ces dernières déploient leurs multiples effectivités. Le premier ensemble recouvre les technologies intervenant dans la pratique en arts numériques. Le deuxième ensemble a trait au milieu des arts numériques et aux modes de l'organisé afférents. Enfin, le troisième ensemble traite du rapport entre les mondes de l'entreprise et la pratique en arts numériques. Ces trois ensembles d'éléments participent de diverses manières à la constitution, au maintien et à la singularisation de pratiques en arts numériques qui déploient leurs effectivités largement au-delà d'un espace social circonscrit ou spécialisé.This thesis examines the paths and practices of digital artists navigating within the multimedia sectors of Montreal. Through the study of the paths of eleven digital artists based in Montreal we found that production practices in digital arts cannot be reduced to the logic of production specific to a single place, whether a private company, a digital arts center or a university. The issue of maintaining these practices leads one to pay attention to the plurality of elements that inform their perpetual (re)constitutions. This requires new ways of theorizing digital artists' paths and practices. We propose a new way of conceptualizing these paths - as trajectories - to highlight the plurality of ways the digital art practices are articulated. They are thus considered in terms of their co-constitutive mediations with different elements. We have identified three sets of elements to account for the maintenance of the practices in digital arts and through which these unfold their multiple effectivities. The first set covers the technologies involved in digital art practices. The second set relates to the digital arts community and the organizational modes characteristic of those locales. Finally, the third set deals with the relationship between the worlds of business and practices in digital arts. These three sets of elements contribute in various ways to the establishment, maintenance and singularity of digital arts practices that deploy their effectivities far beyond a circumscribed or specialized social space.

Full textAbstract:
This thesis examines the evolution of Canadian broadcasting regulation since the adoption of the 1991 Broadcasting Act with a specific focus on the digital television transition. For Canada, this technological shift exemplifies many of the greater changes in public policy in the last two decades: a faith in market mechanisms, light-touch regulation, co-regulatory approaches, and the powerful influence of new technologies. This dissertation will address the following central question: does the policy surrounding the transition to digital television broadcasting pose a challenge to traditional concerns of the role of broadcasting in Canadian democracy? Utilizing the approach of institutional political economy, this study is informed by primary government and industry documents and interviews conducted with key actors within Canadian broadcasting. This dissertation offers a unique contribution to knowledge in three areas: establishing clear parameters for the differences between policy and regulations in Canadian broadcasting; offering the first comprehensive study of the Canadian digital television transition; and analyzing the growth and impact of self and co-regulation in Canadian broadcasting policy. The results of this study speak to the power dynamics amid the range of actors involved in the Canadian policy process, the influence of new technologies, and the greater prevailing policy directions in broadcasting since the 1991 Broadcasting Act was adopted.Cette thèse examine l'évolution de la réglementation canadienne de la radiodiffusion depuis l'adoption de la Loi sur la radiodiffusion (fédérale) en 1991 en se concentrant plus particulièrement sur la transition à la télévision numérique. Pour le Canada, ce changement de cap est révélateur des grandes modifications que les politiques publiques ont connues dans les deux dernières décennies : une foi dans les mécanismes de marché, une réglementation en pointillé, des approches axées sur la coréglementation et la puissante influence des nouvelles technologies. La question centrale étudiée dans ce mémoire est la suivante : la politique sous-jacente à la transition à la télédiffusion numérique constitue-t-elle un défi en regard des préoccupations traditionnelles afférentes au rôle de la radiodiffusion dans la démocratie canadienne ? Adoptant une approche de économie politique institutionnelle, cette étude se fonde sur l'étude de documents gouvernementaux ou provenant des entreprises privées oeuvrant dans le secteur ainsi que sur des entretiens effectués avec certains acteurs clés de la radiodiffusion canadienne. Cette thèse offre une contribution unique au savoir quant à trois aspects : établir des paramètres clairs permettant de différencier les politiques de la réglementation dans le domaine de la radiodiffusion ; offrir la première étude détaillée sur la transition canadienne à la télévision numérique, et présenter une analyse du développement et de l'impact de l'autoréglementation et de la coréglementation dans les politiques canadiennes relatives à la radiodiffusion. Les conclusions de cette étude mettent en lumière les dynamiques de pouvoir existant entre les divers acteurs engagés dans le processus d'élaboration et d'adoption des politiques canadiennes, l'influence des nouvelles technologies et les grandes orientations politiques ayant prévalu dans le domaine de la radiodiffusion depuis l'adoption d

Esta tese discute a medição e a caracterização das redes de distribuição de energia elétrica de baixa tensão (RDE-BT) e externa (outdoor) como meio de comunicação de dados para sistemas power line communication (PLC). São apresentados e discutidos diversos parâmetros obtidos a partir de uma campanha de medição realizada na RDE-BT de uma concessionária brasileira. Dentre os parâmetros analisados destacam-se o tempo de coerência, banda de coerência, espalhamento do atraso, comprimento da resposta ao impulso do canal e capacidade do canal, quando se considera as bandas de frequências de 1,7 a 30 MHz, 1,7 a 50 MHz e 1,7 a 100 MHz. As análises estatísticas evidenciam o potencial da rede de energia elétrica como meio de comunicação e discute os limites dessa potencialidade. Além disso, são propostos modelos de densidade espectral de potência dos ruídos, caracterização esparsa de canais PLC e proposto um modelo para geração de canais PLC variantes no tempo, cujo tempo de coerência entre as realizações dos canais é controlado. A estimação de canais PLC é apresentada como uma oportunidade de aplicação das técnicas de amostragem compressiva. Os resultados relacionados com as modelagens propostas constituem um ferramental de grande utilidade para projetar e analisar o desempenho de sistemas PLC.
This dissertation aims at discussing the measurement and characterization of outdoor electric power grid of low voltage as communication medium (power line communication - PLC). Statistical analyses carried out on several parameters such as average channel gain, coherence time, coherence bandwidth, delay spread, length of the channel impulse response, and channel capacity, when it is considered the frequency bands from 1.7 to 30 MHz, from 1.7 up to 50 MHz, and from 1.7 up to 100 MHz, are presented. These analyses reveal the circumstances in which outdoor and low-voltage electric power grids can be advantageous to support a reliable and efficient PLC system operation. Moreover, power spectral density models of additive noise and sparse representation of PLC channels are proposed. Also, a PLC time-varying channels model generator that makes use of coherence time is introduced. The proposed model generator, which is validated with measured PLC channels, is an effective tool to carry out performance analysis of PLC systems. Finally, PLC channel estimation is highlighted as an opportunity for the application of compressive sampling-based techniques. The use of traditional OFDM - based channel estimation techniques and the ones based on compressive sensing gives some directions for advancing channel estimation techniques for PLC channels.

Resumo: A transmissão de vídeo em redes Wireless é abordada pela pesquisa, devido o grande aumento na utilização dessas redes na ultima década. O acesso à banda larga por essas redes é feito de forma eficiente, rápida e com baixo custo de implementação e manutenção da rede. A motivação para o desenvolvimento é utilizar essas redes e a rede IPTV para promover a interatividade e uma forma do canal de retorno para Sistemas de Televisão Digital, que estão sendo implementadas atualmente no Brasil. O canal de Retorno da TV Digital é importante para o sistema, pois um dos objetivos é prover a interatividade entre os usuários. Isso deve ser feito de forma simples com baixo custo e com tecnologia compatível a região do usuário. A simulação trata de um sistema de transmissão unicast que seria semelhante a uma interatividade local e dedicada. O usuário transmite o conteúdo de uma só vez. Os dados que são transmitidos pela provedora de serviços, são armazenados no set-top-box, e só são modificados em caso de novo fluxo de dados, quando há atualização ou acesso a nova área de serviços. Os testes feitos durante a pesquisa, transmitem conteúdo em tempo real e avaliam de forma quantitativa o desempenho das redes IEEE 802.11b e IEEE 802.11g.
Abstract: The streaming video transmission on Wireless networks is concerned in the research due to the large increase in the use of such networks in the last decade. Broadband access for these networks is made efficiently, quickly and with low implementation and maintenance costs of the network. The motivation for developing this research is to use these networks and IPTV network to promote interactivity and a return channel for digital television system, currently being implemented in Brazil. The return channel is important for the Digital TV system, because one of the goals is to provide interactivity for the users. This should be done in a simple, low cost way and with technology compatible in the region of the user. The simulation deals with a unicast transmission system which is similar to a local and dedicated interactivity. The user transmits all the contents at once. The data transmitted by a service provider are stored on set-top box and are modified only in case of new data flow, when there are updates or access to new area of services. The tests performed during the research, it was broadcasted contents in real time and evaluated quantitative the performance of IEEE 802.11b and IEEE 802.11g networks.

Full textAbstract:
AbstractThere are rapidly growing concerns worldwide about the impact of content aggregation and distribution through digital platforms on traditional media industries and society in general. These have given rise to policy and regulation across the social pillar, including issues of privacy, moderation, and cyberbullying; the public interest/infosphere pillar, with issues such as fake news, the democratic deficit, and the crisis in journalism; and the competition pillar, involving issues based on platform dominance in advertising markets. The cultural pillar, involving the impact of SVODs on the ability of content regulation to support local production capacity, is often bracketed out of these debates. We argue this divide is increasingly untenable due to the convergent complexities of contemporary media and communications policy and regulation. We pursue this argument by offering three issues that bring policy and regulation together across the platform-SVOD divide: digital and global players have been beyond the reach of established broadcasting regulation; the nature of the Silicon Valley playbook for disrupting media markets; and platforms and SVODs now need not only to be aggregators but also contributors to local cultures. We draw on three examples: the European Union, Canada and Australia.

An increasing use of social media platforms and other mobile applications (apps) has led to the creation, purchase, storage, and use of online information and data including personal or financial information, email communications, photographs, or videos. The purposes of this chapter are to discuss digital property and to determine whether under estate planning and administration law digital property can be inherited like other real and personal property. This chapter will examine relevant legislation in Australia, United States (US), and other jurisdictions including Canada, as well as legal cases that have discussed the issue of accessing or transferring digital property held by service providers such as Facebook. It will also discuss examples of service providers' terms of use and whether these terms allow for digital property to be accessed by a third party. It will conclude with recommendations about how an individual can manage their digital property as part of their will or estate.

This chapter presents a multiyear case study in a two-year graduate teacher education program at a large urban university in Canada. This research studies how the incorporation of the TPACK theoretical framework and the concept of global competencies supports pre-service candidates' depth of pedagogical understandings when integrating technology into teaching practice. Online surveys were conducted with students attending a compulsory information and communications technology (ICT) course. Five instances of the course across a four-year time span were studied. Online questionnaires were also given to students and five instructors. Four themes were identified by students and instructors: (1) TPACK helps students integrate the three kinds of knowledge, (2) TPACK allows a focus on pedagogy by defocusing on technology, (3) TPACK is a robust theory, and (4) TPACK takes time to integrate into practice. This chapter offers teacher education program recommendations and suggests directions for future research.

Full textAbstract:
In this chapter, the authors consider the use of digital storytelling as a tool for boundary crossing. Media, as an extension of self, has potential to help cross-cultural learning that benefits all stakeholders, but specifically, immigrants and English Language Learners, who often experience school literacy challenges. The authors used Cultural Historical Activity Theory (CHAT) as a lens to view two teacher case self-studies, one in Canada and one in the U.S.A., and to examine how their use of digital storytelling helped elementary ELL students to learn the language of school as well as transfer their knowledge to other students and educators. The findings indicated the importance of creating avenues through which immigrant English learners can develop interpersonal communication skills critical to being successful across cultures. Through an analysis of the cases, the authors present language learning implications for educators.

Full textAbstract:
This chapter examines the effects of information and communication technologies (ICTs) on storytelling as a practice of communication among transnational families. It describes three technological affordances that are linked to digital storytelling practices of six Colombian migrant families residing in Montreal, Canada: presence, interactivity, and multimodality. After providing an overview of the methodological approach employed in the research study and the techniques used to collect and analyse the data, the chapter discusses the findings with regard to the views of the participant families about the dynamics of their post-migration storytelling experiences. More specifically, it considers the Colombian families' perspectives about being present during their digital interactions. An important finding is that digital mediation seems to be altering family storytelling. For some families, ICTs catalyse storytelling in situations where presence and multimodality take place; for others, ICTs constrain family storytelling when the illusion of nonmediation is not experienced.

Schools in rural communities of the Canadian province of Newfoundland and Labrador have been reorganized in the last decade. Because of rural to urban migration and the consequent challenge to the continued existence of many small schools, new academically and administratively open structures have been established within an Internet-based environment. Accordingly, traditional closed, autonomous schools in this province have increasingly become open sites within Internet-linked teaching and learning environments. What began as a research project linking eight schools in a single Digital Intranet has been extended to include schools across the province managed by a recently established branch of the Department of Education of Newfoundland and Labrador—the Centre for Distance Learning and Innovation. This chapter provides an outline of how information and communication technologies have been used to reshape education in a predominantly rural Canadian province, thereby preparing people for participation in the emerging knowledge-based economy.

Full textAbstract:
Most computers during the Second World War, such as the British code-breaking Colussus machine, had been developed for military use. The effects on law and order and war and peace of computerization, worldwide telecommunications, social media, artificial intelligence (AI), and robotics is the topic of Chapter 6. As in Chapter 5, the most compelling visions of the potential opportunities and dangers have been in science fiction and in film; we begin the chapter by reviewing some memorable examples. We then discuss how technology is used by the police, such as the use of video evidence to sometimes exonerate the police against false accusations of needless brutality. We also examine how citizens are using social media to protect themselves and alert others to what they believe is unwarranted violence or unjust actions by law enforcement. We expand upon Section 5.7’s discussion of citizen mobilization by social media with the goal of regime change. In this context, we discuss how the government (especially police and security services) gains leverage via the surveillance of the digital information and communications of citizens. This surveillance has significantly increased due to security concerns post-9/11. We will examine these developments in the USA, Canada, and the UK, as well as in other parts of the world. We shall also discuss cases of organizations trying to subvert societies that repress and forbid access to the internet, with the goal of enabling its citizens to access the internet freely. Next, we consider ways in which tools of digital disruption are used by a country or government or a set of individuals against others. The timely and current case study explored is on governmental use of hacking and other aggressive digital means to interfere with the electoral processes of another country, or even to disrupt or destabilize the other country. At the extreme, governments engage in cyberterrorism or even cyberwarfare. We shall discuss several recent examples of this and argue that weapons of cyberwarfare could be as catastrophic as nuclear or biological weapons. The technology of warfare has also evolved.

Full textAbstract:
Conventional wisdom holds that the Internet is a technology for the young. However, as this chapter shows, older adults are increasingly adopting digital media, and it is therefore critical to know more about how networks of digital communication are changing their lives in such respects as their interaction with family and friends. The authors draw upon a study using in-depth interviews of older adult residents in East York, a locality in Toronto, Canada. These interviews illuminate the roles that digital media play in managing and strengthening the personal networks of elders. Their findings challenge stereotypes about older adults and their use of the Internet. The chapter makes an evidence-based case that the Internet and related digital media help older adults develop a sense of connectedness versus isolation.

Inter-religious dialogue is expected to increasingly take on the form of online creative conversations that rely on digital data and documents. The first part of this chapter is about the current symbolic obstacles on the road to cultural and religious “intercomprehension” in this context: mainly the incompatibility and the cultural biases of classification systems. To overcome these obstacles (and some others), the authors propose using IEML (Information Economy MetaLanguage), a computable language specially suited to the online intercultural dialogue that was developed at the Canada Research Chair in collective intelligence at the University of Ottawa. The second and main part of this chapter presents some examples of the application of basic IEML categories to the religious domain.

Full textAbstract:
This chapter distinguishes between the digitization of existing archives and born-digital archives, which can be shown through the Canadian Centre of Architecture's (CCA) varying approaches to them. It explains that digitization is the process of converting information into a computer-readable digital format, in which the outcome is the digital representation of objects, documents, and images. It also mentions Mirko Zardini, who explains that CCA curators and conservators do not consider it reasonable to digitize an entire archive. The chapter shows different challenges for born-digital archives and their preservation that sets new obstacles. It discusses the encounter between the computer, the new design and communication tools it affords, and architectural practice that resulted in a significant change.

Full textAbstract:
Digital control and safety plus the complete functional and physical separation between control and safety and also between the safety systems have been key long standing principles of CANDU® nuclear reactor technology. This paper presents a historical evolution of these principles that make CANDU reactors one of the safest technologies in the world today. The original Generation II CANDU 6 reactors started with complete separation of control from safety and the division of safety systems into two groups having strong physical separation such as opposite sides of the reactor or reactor building. Within each group a more moderate distance separation was employed. With the advent of distributed computer technology for control and display functions, key processing equipment is now moved out remote from the control rooms and distributed into channelized field equipment rooms around the reactor building as in the Four-Quadrant concept for ACR-1000™. This new approach is immune to total unavailability of any control room or equipment room due to events such as fire with minimal impact to any of the safety systems regardless of their grouping. In addition to physical separation, appropriate functional partitioning, design rules to avoid communication cross links, and diversity principles are applied to computer based I&C systems as defences against common cause faults.

El Museo Dialoga: el museo y la sociedad en comunicación crítica. Autores: MSc. Luis Pablo Orozco Varela[1] Sra. Mariana Blanco Ortiz[2] Sr. Gustavo Campos Fonseca[3] Sra. María Cubillo González[4] Sr. Javier Nuñez Marín[5]. Resumen La ponencia consiste en compartir y analizar en profundidad el quehacer comunicativo del Museo de Cultura Popular de la Escuela de Historia de la Universidad Nacional de Costa Rica, específicamente a partir de la iniciativa de diálogo virtual denominada “#elmuseodialoga”, la cual ha potencializado la presencia del museo en las redes sociales académicas y ha contribuido a potenciar enlaces dialógicos con académicos, dentro y fuera de la universidad, así como con actores de la sociedad civil en su conjunto. Esta iniciativa surgió ante el desafío presentado por la pandemia COVID 19 con el fin de potencializar acciones de extensión y difusión de carácter virtual por medio del uso de las redes sociales con las que cuenta el museo, por ejemplo, el canal de youtube, Facebook, Instagram, Twitter y linkedin. Para ello, académicos que laboran en el museo y estudiantes de la Escuela de Historia, han aunado esfuerzos en pro de generar una alternativa de comunicación acorde a los nuevos desafíos de la virtualidad. En ese sentido, se ha potenciado a lo largo de poco más de un año, cuarenta ediciones de diálogo virtual, contando con invitados tanto nacionales, como internacionales, esto último dentro de la modalidad #elmuseodialogainternacional. El espacio de diálogo cuenta con tres ejes trasversales que permiten cubrir un amplio espectro de posibilidades temáticas: a) Cultura popular, historia, arte y patrimonio, b) difusión del quehacer académico y c) temas de actualidad nacional e internacional. En el primer eje abordamos todo lo relativo a patrimonio cultural, materia e inmaterial, tradiciones, cultores populares, arte costarricense, entre otros. A partir del segundo eje, trabajamos en difundir el aporte de investigaciones de académicos tanto de la UNA como de otras universidades nacionales e internacional, con el fin de divulgar a públicos más amplios la contribución del conocimiento producido por las universidades a la sociedad en su conjunto. En el caso del tercer eje, reforzamos la relación pasado-presente, generando espacios de lectura de la realidad nacional e internacional, abriendo también horizontes de prospectiva. Palabras claves: Comunicación, Pedagogía, Cultura contemporánea, Patrimonio Cultural, Historia. The Museum Dialogues: the museum and society in critical communication. Resume The presentation consists of sharing and analyzing in depth the communicative work of the Museum of Popular Culture of the School of History of the National University of Costa Rica, specifically from the virtual dialogue initiative called "#elmuseodialoga", which has potentiated the presence of the museum in academic social networks and has contributed to fostering dialogic links with academics, inside and outside the university, as well as with actors from civil society as a whole. This initiative arose in order to enhance virtual extension and dissemination actions through the use of social networks that the museum has, for example, the YouTube channel, Facebook, Instagram, Twitter and LinkedIn. To this end, academics who work at the museum and students from the School of History have joined forces to generate a communication alternative in line with the new challenges of virtuality. In this sense, forty editions of virtual dialogue have been promoted over the course of just over a year, with both national and international guests, the latter within the #elmuseodialogainternacional modality. The dialogue space has three transversal axes that allow covering a wide spectrum of thematic possibilities: a) Popular culture, history, art and heritage, b) dissemination of academic work and c) current national and international issues. In the first axis we address everything related to cultural heritage, material and immaterial, traditions, popular cultists, Costa Rican art, among others. From the second axis, we work on disseminating the contribution of academic research from both the UNA and other national and international universities, in order to disclose to wider audiences, the contribution of the knowledge produced by universities to society as a whole. In the case of the third axis, we reinforce the past-present relationship, generating spaces for reading the national and international reality, also opening prospective horizons.
