Beyond cybersafety: The need to develop social media literacies in pre-teens

Cybersafety has been a mainstay of digital education since computers arrived in classrooms in the mid 1990s. Whether schools encourage students to be ‘cybersmart’ (Australia), ‘netsafe’ (New Zealand) or to be aware of ‘cybersecurity strategies’ (Mexico and Chile) most now devote a relatively large amount of time and money to teaching young people how to ‘stay safe’ online. In this article, we argue that it is time for schools to move beyond the cybersafety discourse to encourage students to think more critically about the digital media they use. Reporting on the digital practices of 276 pre-teens aged 7-12 years in Australia and Uruguay, we contend that the everyday digital challenges young people face are now beyond the scope of most cybersafety programs. Our findings highlight that many of the issues pre-teens are negotiating call for more nuanced and sustained educational programs that support the development of critical social media literacies. In particular, with the proliferation of mass user platforms and artificial intelligence, there is a need for schools to educate students around managing and protecting their personal data. The article concludes with a discussion of the digital learning required for young people in an increasingly datafied society

Extending 5G capacity planning through advanced subscriber behavior-centric clustering

his work focuses on providing enhanced capacity planning and resource management for 5G networks through bridging data science concepts with usual network planning processes. For this purpose, we propose using a subscriber-centric clustering approach, based on subscribers’ behavior, leading to the concept of intelligent 5G networks, ultimately resulting in relevant advantages and improvements to the cellular planning process. Such advanced data-science-related techniques provide powerful insights into subscribers’ characteristics that can be extremely useful for mobile network operators. We demonstrate the advantages of using such techniques, focusing on the particular case of subscribers’ behavior, which has not yet been the subject of relevant studies. In this sense, we extend previously developed work, contributing further by showing that by applying advanced clustering, two new behavioral clusters appear, whose traffic generation and capacity demand profiles are very relevant for network planning and resource management and, therefore, should be taken into account by mobile network operators. As far as we are aware, for network, capacity, and resource management planning processes, it is the first time that such groups have been considered. We also contribute by demonstrating that there are extensive advantages for both operators and subscribers by performing advanced subscriber clustering and analytics.info:eu-repo/semantics/publishedVersio

Representações de gênero na publicidade televisiva infantil: as perceções e a literacia para a publicidade das crianças

Children are becoming consumers at increasingly younger age and are more influential in consumption decisions within the family. Television still is one of the main ways they are exposed to advertising. Our study focuses on gender stereotypes on TV advertisements for children and combines a content analysis of advertisements and focus groups with children between 7 and 12 years old. Our findings show that, during a period of 3 months, about 75% of TV advertisements for children contain gender stereotypes. In addition, children are able to recognize such stereotypes, and in general do not identify or agree with the way each gender is portrayed. Finally, children display good levels of advertising literacy, as they are able to recognize the intentions of the brands in the commercials.As crianças tornam-se consumidores cada vez mais cedo, e são cada vez mais influentes no consumo da família. A televisão ainda é uma das principais formas através das quais são expostas à publicidade. O nosso estudo, realizado em Portugal, foca-se em estereótipos de gênero na publicidade televisiva infantil e combina uma análise de conteúdo a anúncios com grupos de discussão com crianças entre os 8 e os 12 anos. Os nossos resultados mostram que, em 3 meses, 75% dos anúncios televisivos para crianças continham estereótipos de gênero. As crianças são capazes de reconhecer esses estereótipos e, em geral, não se identificam ou não concordam com essas representações dos gêneros. Finalmente, as crianças revelaram bons níveis de literacia para a publicidade, sendo capazes de reconhecer a intenção persuasiva das marcas.info:eu-repo/semantics/publishedVersio

Improved planning and resource management in next generation green mobile communication networks

In upcoming years, mobile communication networks will experience a disruptive reinventing process through the deployment of post 5th Generation (5G) mobile networks. Profound impacts are expected on network planning processes, maintenance and operations, on mobile services, subscribers with major changes in their data consumption and generation behaviours, as well as on devices itself, with a myriad of different equipment communicating over such networks. Post 5G will be characterized by a profound transformation of several aspects: processes, technology, economic, social, but also environmental aspects, with energy efficiency and carbon neutrality playing an important role. It will represent a network of networks: where different types of access networks will coexist, an increasing diversity of devices of different nature, massive cloud computing utilization and subscribers with unprecedented data-consuming behaviours. All at greater throughput and quality of service, as unseen in previous generations. The present research work uses 5G new radio (NR) latest release as baseline for developing the research activities, with future networks post 5G NR in focus. Two approaches were followed: i) method re-engineering, to propose new mechanisms and overcome existing or predictably existing limitations and ii) concept design and innovation, to propose and present innovative methods or mechanisms to enhance and improve the design, planning, operation, maintenance and optimization of 5G networks. Four main research areas were addressed, focusing on optimization and enhancement of 5G NR future networks, the usage of edge virtualized functions, subscriber’s behavior towards the generation of data and a carbon sequestering model aiming to achieve carbon neutrality. Several contributions have been made and demonstrated, either through models of methodologies that will, on each of the research areas, provide significant improvements and enhancements from the planning phase to the operational phase, always focusing on optimizing resource management. All the contributions are retro compatible with 5G NR and can also be applied to what starts being foreseen as future mobile networks. From the subscriber’s perspective and the ultimate goal of providing the best quality of experience possible, still considering the mobile network operator’s (MNO) perspective, the different proposed or developed approaches resulted in optimization methods for the numerous problems identified throughout the work. Overall, all of such contributed individually but aggregately as a whole to improve and enhance globally future mobile networks. Therefore, an answer to the main question was provided: how to further optimize a next-generation network - developed with optimization in mind - making it even more efficient while, simultaneously, becoming neutral concerning carbon emissions. The developed model for MNOs which aimed to achieve carbon neutrality through CO2 sequestration together with the subscriber’s behaviour model - topics still not deeply focused nowadays – are two of the main contributions of this thesis and of utmost importance for post-5G networks.Nos próximos anos espera-se que as redes de comunicações móveis se reinventem para lá da 5ª Geração (5G), com impactos profundos ao nível da forma como são planeadas, mantidas e operacionalizadas, ao nível do comportamento dos subscritores de serviços móveis, e através de uma miríade de dispositivos a comunicar através das mesmas. Estas redes serão profundamente transformadoras em termos tecnológicos, económicos, sociais, mas também ambientais, sendo a eficiência energética e a neutralidade carbónica aspetos que sofrem uma profunda melhoria. Paradoxalmente, numa rede em que coexistirão diferentes tipos de redes de acesso, mais dispositivos, utilização massiva de sistema de computação em nuvem, e subscritores com comportamentos de consumo de serviços inéditos nas gerações anteriores. O trabalho desenvolvido utiliza como base a release mais recente das redes 5G NR (New Radio), sendo o principal focus as redes pós-5G. Foi adotada uma abordagem de "reengenharia de métodos” (com o objetivo de propor mecanismos para resolver limitações existentes ou previsíveis) e de “inovação e design de conceitos”, em que são apresentadas técnicas e metodologias inovadoras, com o principal objetivo de contribuir para um desenho e operação otimizadas desta geração de redes celulares. Quatro grandes áreas de investigação foram endereçadas, contribuindo individualmente para um todo: melhorias e otimização generalizada de redes pós-5G, a utilização de virtualização de funções de rede, a análise comportamental dos subscritores no respeitante à geração e consumo de tráfego e finalmente, um modelo de sequestro de carbono com o objetivo de compensar as emissões produzidas por esse tipo de redes que se prevê ser massiva, almejando atingir a neutralidade carbónica. Como resultado deste trabalho, foram feitas e demonstradas várias contribuições, através de modelos ou metodologias, representando em cada área de investigação melhorias e otimizações, que, todas contribuindo para o mesmo objetivo, tiveram em consideração a retro compatibilidade e aplicabilidade ao que se prevê que sejam as futuras redes pós 5G. Focando sempre na perspetiva do subscritor da melhor experiência possível, mas também no lado do operador de serviço móvel – que pretende otimizar as suas redes, reduzir custos e maximizar o nível de qualidade de serviço prestado - as diferentes abordagens que foram desenvolvidas ou propostas, tiveram como resultado a resolução ou otimização dos diferentes problemas identificados, contribuindo de forma agregada para a melhoria do sistema no seu todo, respondendo à questão principal de como otimizar ainda mais uma rede desenvolvida para ser extremamente eficiente, tornando-a, simultaneamente, neutra em termos de emissões de carbono. Das principais contribuições deste trabalho relevam-se precisamente o modelo de compensação das emissões de CO2, com vista à neutralidade carbónica e um modelo de análise comportamental dos subscritores, dois temas ainda pouco explorados e extremamente importantes em contexto de redes futuras pós-5G

YouTube Preferences and Practices of Preadolescents: Findings From a Study Carried Out in Catalonia

Dados recentes confirmam o papel central que o YouTube desempenha na vida mediática dos jovens ocidentais e, em especial, nas práticas mediáticas dos adolescentes e pré-adolescentes. O presente estudo pretende analisar as práticas mediáticas e os usos preferenciais que os pré-adolescentes dão ao YouTube. Apoiada na teoria dos usos e gratificações, a investigação aplica métodos de análise qualitativos e quantitativos. Através de um questionário subministrado a 1.406 pré-adolescentes (x = 12, 11 anos de idade) oriundos de 41 escolas secundárias e de três grupos-focais levados a cabo em três escolas distintas com seis participantes cada um (três raparigas e três rapazes), o presente estudo mostra que para estes jovens o YouTube é considerado simultaneamente como uma rede social e como um arquivo de material audiovisual. O estudo também revela que os jovens gostam do conteúdo disponível no YouTube e, em particular, dos vídeos de música e de humor (entretenimento) e de tutoriais (auto-aprendizagem). Em geral, os jovens sentem menor apelo pelas funções interativas (por exemplo, partilhas e comentários). O uso que fazem do YouTube revela que o incorporaram às suas vidas quotidianas e que o usam predominantemente para consumir conteúdos mediáticos de uma forma “tradicional” e “não interativa”, semelhante ao uso que se faz tradicionalmente da televisão. Apesar disso, não o consideram uma “nova” televisão. Os pré-adolescentes objeto deste estudo usam o YouTube principalmente como fonte de entretenimento e, secundariamente, como fonte de auto-aprendizagem e de socialização. Estudos futuros terão de ser levados a cabo no sentido de aprofundar o conhecimento sobre as possibilidades que o YouTube e outras redes sociais oferecem aos pré-adolescentes para que estes sejam prosumidores.Recent data confirm the central role that YouTube plays in the media life of young people in the west, and especially in the media practices of adolescents and preadolescents. This article presents a study on tweens’ YouTube preferences and media practices. The study was based on the uses and gratification theory and applied a quantitative-qualitative approach: a questionnaire was administered to 1,406 preadolescents (x = 12, 11 years-old) from 41 secondary schools, and three focus groups with six participants (three girls and three boys) each were carried out in three schools. The results reveal that the tweens participating in the study consider YouTube as a social media and a video catalogue. They especially like YouTube’s content, in particular entertainment (music and humour) and self-learning (tutorials); however, they generally dislike its interactive functions (e.g., sharing and commenting). Moreover, their media practices on YouTube reveal that tweens incorporate YouTube into their everyday media life within other social media, although they use it predominantly to consume media content in a “traditional”/“non-interactive” way, similar to traditional television use. Despite this they do not consider it as a “new” television. Finally, tweens in our study use YouTube especially for entertainment, and, on a second level, for self-learning and socialising functions. Further studies need to be carried out to go deeper into the prosumption possibilities for tweens’ both on YouTube and other social media

Hanging Out, Messing Around, and Geeking Out

The tenth-anniversary edition of a foundational text in digital media and learning, examining new media practices that range from podcasting to online romantic breakups. Hanging Out, Messing Around, and Geeking Out, first published in 2009, has become a foundational text in the field of digital media and learning. Reporting on an ambitious three-year ethnographic investigation into how young people live and learn with new media in varied settings—at home, in after-school programs, and in online spaces—it presents a flexible and useful framework for understanding the ways that young people engage with and through online platforms: hanging out, messing around, and geeking out, otherwise known as HOMAGO. Integrating twenty-three case studies—which include Harry Potter podcasting, video-game playing, music sharing, and online romantic breakups—in a unique collaborative authorship style, Hanging Out, Messing Around, and Geeking Out combines in-depth descriptions of specific group dynamics with conceptual analysis. Since its original publication, digital learning labs in libraries and museums around the country have been designed around the HOMAGO mode and educators have created HOMAGO guidebooks and toolkits. This tenth-anniversary edition features a new introduction by Mizuko Ito and Heather Horst that discusses how digital youth culture evolved in the intervening decade, and looks at how HOMAGO has been put into practice. This book was written as a collaborative effort by members of the Digital Youth Project, a three-year research effort funded by the John D. and Catherine T. MacArthur Foundation and conducted at the University of California, Berkeley, and the University of Southern California

Bullying in a networked era: a literature review

This research update presents an aggregation and summary of recent academic literature on youth bullying. The purpose of this document is to “translate” scholarly research for a concerned public audience, which may include but is not limited to parents, caregivers, educators, and practitioners. This translation highlights recent findings and developments in the literature and makes them accessible to the informed but non-expert reader. The document’s two guiding questions are “What is bullying?” (Section I) and “What can be done about bullying?” (Section II). Section I begins with a brief overview of key definitions and related research conversations and then addresses bullying’s prevalence, the types of individuals involved in bullying, the characteristics of individuals involved and the consequences of their involvement, and community-level dynamics related to bullying. Section II covers four areas where action has been taken to address problems associated with bullying – school policy, curricula, school climate, and parents – and ends on a note about approaches that mix or cut across these areas. The purpose is to render lessons learned from research and assessment accessible to those interested in deepening or expanding their knowledge of bullying-related issues

Effect Of Surfactant Chain Length Difference In Mixed Surfactant Systems On Self Emulsification Of Poorly Soluble Drug

In the present investigation the effect of chain length difference (Δn) of different surfactant mixtures was evaluated on self emulsifying capability of self emulsifying drug delivery system of aceclofenac. Three surfactants of Tween series namely Tween 20, Tween 40 and Tween 80 were used for the study. The lipid carrier used was almond oil. Surfactant mixtures were prepared by combining Tween 20 and Tween 80 (Δn=6), Tween 20 and Tween 40 (Δn=4), Tween 40 and Tween 80 (Δn=2) in definite proportion. Pseudoternary diagram study was carried out to determine the surfactant mixture which provides the largest microemulsifying region. The pseudoternary diagram study revealed that the microemulsifying region increases as the difference in chain length increases. So, Tween 80 and Tween 20 were selected for formulation development, the proportion of which is further optimized by simplex lattice design. The formulations were prepared and subjected to different evaluation parameters. The optimized formulation has a particle size of 68.95 nm and zeta potential of -15.3 mV
