Speaking Out Online:The Benefits and Risks of Speaking About Sexual Violence for Young People

Speaking out about sexual violence has been a fundamental part of feminist politics since the 1970s. The practice of narrating experiences of violence, either publicly or to friends and family aims to combat the culture of silence and stigmatisation that surrounds sexual violence while also helping individuals to gain a sense of empowerment and connect with other survivors. However, speaking out also contains inherent risks, especially for young people. Survivors may meet with stigmatising or disbelieving responses, and they may lose control over who knows their story and the way in which it is told and retold.
These risks and benefits are altered, and potentially exacerbated, in an online environment. While social media may increase survivors’ ability to contact and connect with others with similar experiences it also makes it harder to control when and how their story is shared. The disjuncture between online and offline environments may also increase feelings of stigmatisation and isolation.
There is a need to explore the specific risks and benefits of speaking out online given both young people’s extensive use of social media for social interactions and the increasing tendency for support and educational services targeted at young people to make use of social media and online environments. This paper draws on literature and some preliminary research to consider both risks and benefits of speaking out online and to open a conversation about the creation of supportive spaces and mechanisms for young people to speak about sexual violence in online environments.

A educação para o desenvolvimento sustentável na formação de professores: a Web 2.0 e as interações numa comunidade de prática online

A Educação para o Desenvolvimento Sustentável (EDS) é o cerne de um paradigma emergente na educação do século XXI. A EDS constitui-se um processo de aprendizagem holístico e sistémico e tem como função ensinar a viver de maneira sustentável. Apresenta-se como uma abordagem pedagógica inovadora, que combina aprendizagens ativas e participativas, suportadas por uma multiplicidade de estratégias didático-pedagógicas. Objetiva a promoção da capacidade de pensamento crítico, da resolução de problemas e da tomada de decisão, baseada em valores, por parte dos alunos. Para a implementação da EDS é fundamental que os professores tenham consciência de que lidar com as questões da sustentabilidade, na sala de aula, implica dotarem-se de competências específicas. É, portanto, necessário investir na formação de educadores e formadores; o que compreende o seu desenvolvimento profissional, focado no aperfeiçoamento das suas competências, de modo a potenciar novos processos na aprendizagem coerentes com os princípios da EDS. Neste contexto, no presente estudo, foi criada uma Oficina de Formação para professores do ensino básico, na modalidade b-learning, visando a criação de um espaço de formação que permitisse a integração das TIC/Web 2.0 na prática docente, mais concretamente no apoio à inclusão da EDS no currículo. Partindo do pressuposto que as TIC/Web 2.0 são ferramentas que nos oferecem novas oportunidades, pela sua versatilidade de disseminação do conhecimento, e que permitem reorientar o ensino e a aprendizagem sustentados na teoria sócio-construtivista, promovendo o trabalho colaborativo, criou-se uma Comunidade de Prática online. Recorreu-se, para o efeito, a uma plataforma de alojamento de redes sociais virtuais, o Grouply; visando o estabelecimento de interações entre os professores, a partilha de experiências, recursos e conhecimento, indutores da (re)configuração de práticas ao nível da integração das ferramentas da Web 2.0 no contexto da EDS e, ainda, objetivando promover a atualização, o aperfeiçoamento e a aquisição de novas competências pedagógicas contribuindo para o seu desenvolvimento profissional e social. Metodologicamente o presente estudo assumiu uma natureza qualitativa, segundo um design de investigação-ação, o que implicou um plano de ação realizado numa espiral de três ciclos de investigação-ação: recurso a diferentes técnicas e instrumentos de recolha de dados, particularmente o inquérito por questionário e entrevista, realizados aos professores que frequentaram a oficina de formação; observação com base no diário da Investigadora com os registos de observação das sessões de grupo, reflexões da Investigadora/Formadora e das sessões de acompanhamento individual (Supervisão pedagógica), realizadas ao longo da referida oficina; análise documental dos e-portefolios com registos das reflexões individuais de cada uma das sessões da oficina, as reflexões finais dos professores e o registo dos post´s no fórum de discussão, blogs e Whiteboard da Comunidade de Prática online. Decorrente da análise e discussão dos resultados obtidos, o trabalho realizado sugere que os professores adquiriram/desenvolveram competências em EDS e digitais, tendo-se verificado que a oficina de formação contribui para algumas mudanças nas práticas dos professores.

Comunidades de prática online e a construção de competências para o ensino ativo

O presente estudo foi realizado no âmbito da formação continuada de professores através das interações numa Comunidade de Prática online (CoP online). Nas CoPs ocorrem a partiha de dúvidas e problemas comuns ao trabalho dos docentes. Quando as interações são mediadas por computadores, sejam estas síncronas ou assíncronas, ultrapassam as barreiras de espaço e tempo, se adequando ao cotidiano dos professores, invariavelmente tomado por múltiplas atividades. Nesta investigação delineamos os seguintes objetivos: i) Construir uma CoP online ancorada no software social Facebook, como espaço virtual de interação entre os participantes; ii) Comprender as interações através duma CoP online como etapa na construção de competências; iii) Criar e desenvolver um programa de formações presenciais e online com vistas à desenvover as competências de Questionamento e Argumentação; e, iv) Avaliar os impactos da formação através da CoP online no desenvolvimento das competências do Questionamento e da Argumentação enquanto estratégia de promoção do ensino ativo. Como estratégia, optamos em promover as interações através do Facebook por não ocasionar custos aos participantes e por atender ao modelo de presença virtual já existente. Participaram das interações professores em exercício da Autarquia do Ensino Superior de Garanhuns (AESGA), situada no interior de Pernambuco, Brasil. As interações decorreram no período de Abril de 2012 até Março de 2013, numa comunidade fechada, de livre adesão através de convite. Para solidificar a aprendizagem através da CoP online promovemos dois ciclos de formação, um presencial e um online. Em ambas as intervenções visamos o desenvolvimento das competências do Questionamento e da Argumentação por entendermos que estas são competências instrumentais para o desenvolvimento do Pensamento Crítico e da reflexão essenciais ao docente na revisão constante de suas práticas. Nas sessões online, realizadas com o apoio do Skype e concretizadas no software ArguQuest para dinamizar atividades práticas no desenvolvimento das competências do Questionamento e da Argumentação do professor, oportunizando a este a construção coletiva de estratégias alternativas de ensino e de aprendizagem, fundamentadas no ensino ativo. O estudo foi realizado através dum estudo de caso único, alicerçado no paradigma naturalista e de abordagem qualitativa. Os dados de cariz numérico fundamentaram as análises qualitativas, promovendo também a triangulação dos dados. As interações entre os professores foram analisadas através do modelo IAM (Interaction Analysis Model) proposto por Gunawardena, Lowe e Anderson (1997), que tem como objetivo determinar se o conhecimento foi cosntruído através das interações e qual o grau de mudança do entendimento decorrente das interações. Para verificar esta construção do conhecimento analisamos os excertos de episódios interativos com apoio do software de análise qualitativa WebQDA (Neri de Souza, Costa & Neri de Souza, 2012). A análise das situações de aprendizagem planejadas e desenvolvidas demonstraram que as TIC, nomeadamente os softwares sociais, podem ser aplicados com eficiência no desenvolvimento de competências dos professores em exercício, apresentando-se como alternativa para a promoção da formação continuada de docentes. Em relação ao desenvolvimento das competências do Questionamento e da Argumentação, percebemos que os docentes foram sensibilizados para trabalhar com uma metodologia interativa, promovendo um ambiente favorável à aprendizagem ativa. Através da aplicação adaptada do modelo de construção de conhecimento preconizado no ArguQuest, foi possível acompanhar a prática do docente junto aos seus alunos, ampliando o seu repertório didático, e, sobretudo, implantando uma forma de aprender fundamentada na construção compartilhada de Questionamentos e Argumentos.

Perceptions of some teachers about the similarities and/or differences in teaching online versus in a classroom environment /

The introduction of computer and communications technology, and particularly the internet, into education has opened up some new possibilities for teaching and learning. Courses designed and delivered in an online environment offer the possibility of highly interactive and individually focussed teaching and learning experiences. However, online courses also present new challenges for both teachers and students. A qualitative study was conducted to explore teachers' perceptions about the similarities and differences in teaching in the online and face-to-face (F2F) environments. Focus group discussions were held with 5 teachers; 2 teachers were interviewed in depth. The participants, 3 female and 2 male, were full-time teachers from a large College of Applied Arts & Technology in southern Ontario. Each of them had over 10 years of F2F teaching experience and each had been involved in the development and teaching of at least one online course. i - -; The study focussed on how teaching in the online environment compares with teaching in the F2F environment, what roles teachers and students adopt in each setting, what learning communities mean online and F2F and how they are developed, and how institutional policies, procedures, and infrastructure affect teaching and learning F2F and online. This study was emic in nature, that is the teachers' words determine the themes identified throughout the study. The factors identified as affecting teaching in an online environment included teacher issues such as course design, motivation to teach online, teaching style, role, characteristics or skills, and strategies. Student issues as perceived by the teachers included learning styles, role, and characteristics or skills. As well, technology issues such as a reliable infrastructure, clear role and responsibilities for maintaining the infrastructure, support, and multimedia capability affected teaching online. Finally, administrative policies and procedures, including teacher selection and training, registration and scheduling procedures, intellectual property and workload policies, and the development and communication of a comprehensive strategic plan were found to impact on teaching online. The teachers shared some of the benefits they perceived about teaching online as well as some of the challenges they had faced and challenges they perceived students had faced online. Overall, the teachers feh that there were more similarities than differences in teaching between the two environments, with the main differences being the change from F2F verbal interactions involving body language to online written interactions without body language cues, and the fundamental reliance on technology in the online environment. These findings support previous research in online teaching and learning, and add teachers' perspectives on the factors that stay the same and the factors that change when moving from a F2F environment to an online environment.

Online Dispute Resolution: Some Implications for the Emergence of Law in Cyberspace

"L’auteur Ethan Katsh analyse les problématiques posées par les relations de la communauté virtuelle de l’Internet et son processus en ligne de résolution des conflits. Il explique comment le cyberespace constitue un environnement intégral et indépendant qui développe ses propres règles normatives. L’évolution des normes au sein du cyberespace semble être une conséquence des interactions entre les acteurs, sans intervention législative fondamentale de la part des états. L’auteur trace l’évolution, depuis le début des années 1990, du processus en ligne de résolution des différends, principalement dans le domaine du commerce électronique. L’accroissement rapide des relations commerciales électroniques a entraîné une hausse des litiges dans ce domaine. Dans le cadre de tels litiges, les moyens en ligne de résolution des conflits offrent aux justiciables plus de facilité, de flexibilité et d’accessibilité que les moyens alternatifs traditionnels de résolution des conflits. C’est donc dans ce contexte qu’a été développé le système ""Squaretrade"" qui a pour objectif d’aider la résolution de conflits entre les utilisateurs de ""E-Bay"". Ce système présente l’avantage important d’encadrer et d’uniformiser le processus de résolution en définissant les termes généraux et spécifiques du conflit. L’auteur soutient que la principale fonction d’un tel système est d’organiser et d’administrer efficacement les communications entre les parties. Ainsi, cette fonction préserve le ""paradigme de la quatrième personne"", nécessaire aux processus alternatifs traditionnels de résolution de conflits. Par ailleurs, cette fonction, en tant que partie intégrante du programme informatique, constitue pour les justiciables une alternative intéressante aux règles législatives. Pour l’auteur, l’analyse de ce phénomène soulève des questions importantes concernant la création de normes et leur acceptation par les citoyens. L’auteur analyse par la suite le concept général de la formation des normes dans le contexte d’un environnement non régularisé. Il soutient que les normes émergeantes doivent toujours viser à développer une forme de légitimité auprès des justiciables. Dans le cadre du processus en ligne de résolution des conflits, cette légitimité doit être acquise autant auprès des parties au litige qu’auprès de la population en général. Toutefois, les attentes des parties au litige sont souvent très différentes de celles du public. L’auteur illustre ainsi comment certains processus en ligne de résolution de conflit ne réussissent pas à obtenir une telle légitimité, alors que d’autres s’établissent en tant qu’institutions reconnues. Dans ce contexte, les institutions en ligne de résolution de conflits devront développer leur propre valeur normative. Ainsi, les moyens en ligne de résolution des conflits remettent en question le processus traditionnel de formation des normes et peuvent être considérés comme des éléments d’un nouvel environnement normatif."

Online customer experience in e-retailing: an empirical model of antecedents and outcomes

The theoretical understanding of online shopping behavior has received much attention. Less focus has been given to the formation of the customer experience (CE) that results from online shopper interactions with e-retailers. This study develops and empirically tests a model of the relationship between antecedents and outcomes of online customer experience (OCE) within Internet shopping websites using an international sample. The study identifies and provides operational measures of these variables plus the cognitive and affective components of OCE. The paper makes contributions towards new knowledge and understanding of how e-

Imbalanced functional link between executive control network and reward network explain the online-game seeking behaviors in Internet gaming disorder

Literatures have shown that Internet gaming disorder (IGD) subjects show impaired executive control and enhanced reward sensitivities than healthy controls. However, how these two networks jointly affect the valuation process and drive IGD subjects' online-game-seeking behaviors remains unknown. Thirty-five IGD and 36 healthy controls underwent a resting-states scan in the MRI scanner. Functional connectivity (FC) was examined within control and reward network seeds regions, respectively. Nucleus accumbens (NAcc) was selected as the node to find the interactions between these two networks. IGD subjects show decreased FC in the executive control network and increased FC in the reward network when comparing with the healthy controls. When examining the correlations between the NAcc and the executive control/reward networks, the link between the NAcc - executive control network is negatively related with the link between NAcc - reward network. The changes (decrease/increase) in IGD subjects' brain synchrony in control/reward networks suggest the inefficient/overly processing within neural circuitry underlying these processes. The inverse proportion between control network and reward network in IGD suggest that impairments in executive control lead to inefficient inhibition of enhanced cravings to excessive online game playing. This might shed light on the mechanistic understanding of IGD.

Languaging in virtual learning sites : studies of online encounters in the language-focused classroom

This thesis focuses upon a series of empirical studies which examine communication and learning in online glocal communities within higher education in Sweden. A recurring theme in the theoretical framework deals with issues of languaging in virtual multimodal environments as well as the making of identity and negotiation of meaning in these settings; analyzing the activity, what people do, in contraposition to the study of how people talk about their activity. The studies arise from netnographic work during two online Italian for Beginners courses offered by a Swedish university. Microanalyses of the interactions occurring through multimodal video-conferencing software are amplified by the study of the courses’ organisation of space and time and have allowed for the identification of communicative strategies and interactional patterns in virtual learning sites when participants communicate in a language variety with which they have a limited experience. The findings from the four studies included in the thesis indicate that students who are part of institutional virtual higher educational settings make use of several resources in order to perform their identity positions inside the group as a way to enrich and nurture the process of communication and learning in this online glocal community. The sociocultural dialogical analyses also shed light on the ways in which participants gathering in discursive technological spaces benefit from the opportunity to go to class without commuting to the physical building of the institution providing the course. This identity position is, thus, both experienced by participants in interaction, and also afforded by the ‘spaceless’ nature of the online environment.

Conhecimento, sociabilidade e lazer em jogos online : SubTítulo: uma etnografia na "Lan House do Paulo" em São Gonçalo do Amarante-RN

In a highly dynamic society such as we live, have access to the virtual world is an increasingly common practice, is aiming to study, work or to search leisure through chat rooms, sites and games, being incorporated by the most varied groups that end up appropriating these new possibilities of interaction, shaping them in order to adapt them to their needs / wants. The specific purposes pursued through the use of tools available over the Internet can vary considerably when one takes into account specific user groups, which makes the topic quite relevant to problematization, especially when we take into account access through lan houses. This research seeks to study the networks of knowledge, sociability and leisure formed by young people who frequented the "Lan house do Paulo" in São Gonçalo do Amarante - RN based on the use of the online role-playing-game World of Warcraft, which makes possible the interaction of several users through an avatar resident in a virtual world, theoretically questioning the importance of this type of platform for the development and maintenance of social interactions among its users

Constraint-based analysis of gene interactions using restricted boolean networks and time-series data

Abstract Background A popular model for gene regulatory networks is the Boolean network model. In this paper, we propose an algorithm to perform an analysis of gene regulatory interactions using the Boolean network model and time-series data. Actually, the Boolean network is restricted in the sense that only a subset of all possible Boolean functions are considered. We explore some mathematical properties of the restricted Boolean networks in order to avoid the full search approach. The problem is modeled as a Constraint Satisfaction Problem (CSP) and CSP techniques are used to solve it. Results We applied the proposed algorithm in two data sets. First, we used an artificial dataset obtained from a model for the budding yeast cell cycle. The second data set is derived from experiments performed using HeLa cells. The results show that some interactions can be fully or, at least, partially determined under the Boolean model considered. Conclusions The algorithm proposed can be used as a first step for detection of gene/protein interactions. It is able to infer gene relationships from time-series data of gene expression, and this inference process can be aided by a priori knowledge available.

Entwicklung einer Online-Kopplung der Gelelektrophorese mit der induktiv gekoppelten Plasma-Massenspektrometrie und deren Anwendung in der Bioanalytik

Die Elementmassenspektrometrie wurde in den letzten Jahren sehr erfolgreich zur Aufklärung verschiedener Fragestellungen in der Bioanalytik eingesetzt. Hierbei spielen vor allem Kopplungstechniken von Trennmethoden wie der Flüssigchromatographie (LC) oder der Kapillarelektrophorese (CE) mit der induktiv gekoppelten Plasma-Massenspektrometrie (ICP-MS) als Multielementdetektor mit hervorragenden Quantifizierungseigenschaften eine entscheidende Rolle bei der Untersuchung von Biopolymeren und deren Wechselwirkung mit verschiedenen Metallen. So wurden beispielsweise verschiedene Methoden für die Trennung und Detektion von Metalloproteinen oder DNA-Metall-Addukten in unterschiedlichen Probenmaterialien entwickelt. Die traditionelle und leistungsstärkste Trennmethode für Biopolymere aller Art, die Gelelektrophorese, wurde jedoch bislang nicht in einem Online-Verfahren an die ICP-MS gekoppelt, um solche Fragestellungen zu bearbeiten. Verschiedene Versuche auf der Basis der Laserablation wurden in diese Richtung unternommen, wobei diese Techniken als sehr umständlich und zeitaufwändig anzusehen sind. In dieser Arbeit wird erstmals die technische Realisierung einer Online-Kopplung der Gelelektrophorese mit der ICP-MS beschrieben. Das System basiert auf einem Prinzip aus der präparativen Gelelektrophorese, in welcher eine kontinuierliche Elution der getrennten Komponenten aus dem Gel während der laufenden Elektrophorese durchgeführt wird. Die eluierten Komponenten werden mit dem Elutionspuffer direkt in das Zerstäubersystem des ICP-MS geführt. Die ersten Untersuchungen wurden am Beispiel der Fragemente von doppelsträngiger DNA (dsDNA) durchgeführt. Kommerziell erhältliche Standardlösungen wurden mit der Online-GE-ICP-MS mittels Detektion von 31P an einem hochauflösenden Massenspektrometer mit einer Massenauflösung von 4000 analysiert. Die Trennbedingungen (z.B. pH-Wert oder Ionenstärke der Pufferlösungen) wurden für die Trennung von dsDNA-Fragementen in Agarosegelen optimiert und auf verschiedene dsDNA-Fragmente angewandt. In einem nächsten Schritt wurden die Quantifizierungsmöglichkeiten für Biopolymere untersucht. Sehr kleine Mengen an dsDNA konnten mit einer Präzision von weniger als 3% quantifiziert werden. Hierfür kamen verschiedene Möglichkeiten der externen Kalibration zum Einsatz, wie der Kalibration mit einem Phosphat-Standard oder einem kommerziell erhältlichen quantitativen dsDNA-Standard. Um das Potenzial der entwickelten Methode für die Untersuchung von Biopolymer-Metall-Wechselwirkungen zu demonstrieren, wurden Oligonukleotide mit Cisplatin unter physiologischen Bedingungen inkubiert und die Reaktionsprodukte mit der Online-GE-ICP-MS mittels 31P- und 195Pt-Detektion untersucht. Verschiedene Cisplatin-Oligonukleotid-Addukte konnten auf diese Weise beobachtet werden, was zur Identifizierung die Anwendung der MALDI-TOF-MS als komplementärer Form der Massenspektrometrie notwendig machte. Abschließend wurde die Isotopenverdünnungsanalyse zum Zweck der Quantifizierung herangezogen.
