Digital unterwegs ohne das virtuelle soziale Netzwerk – qualitative Studie über Facebook-Verweigerung und Virtual Identity Suicide

Das virtuelle soziale Netzwerk Facebook feiert seinen zehnten Geburtstag. Mit über einer Milliarde aktiver Nutzer ist es seit seiner Entstehung zur weltweit größten Internetplattform zur Kommunikation avanciert. Dennoch gibt es in Deutschland eine große Anzahl an Menschen, die sich zwar täglich im Internet bewegt, aber auf eine Mitgliedschaft bei Facebook verzichtet. In dieser Arbeit werden die Gründe untersucht, warum manche Personen Facebook nicht nutzen. Die Leitfrage der Arbeit lautet: „Warum nutzen ausgewählte deutsche Internetnutzer Facebook nicht?“. Es wird zwischen zwei unterschiedlichen Personenkreisen, den Nicht- und den Ex-Nutzern, unterschieden. Basierend auf Leitfadeninterviews mit 25 Befragten, die mittels einer qualitativen Inhaltsanalyse ausgewertet werden, werden elf verschiedene Gründe für eine Verweigerung von Facebook identifiziert. Für die Nicht-Nutzer stellt die Art der Kommunikation den zentralen Grund dar, Facebook nicht zu verwenden. Die Ex-Nutzer wiederum sehen den fehlenden Nutzen der Anwendung als wichtigstes Argument gegen Facebook.

Virtual Infants in Zoo Indigo’s Under the Covers This is Now, This is Live…

The article This is Live this is now (2011), contextualises the performance Under the Covers (2009) by Zoo Indigo. The journal article is written by Ildiko Rippel on behalf of Zoo Indigo theatre company (Rosie Garton and Ildiko Rippel) and it is published in the online Body, Space and Technology Journal:

Protecting children from sex offenders online: when strangers become 'virtual friends'

This article describes findings from research funded by the Metropolitan Police and Crimestoppers which aimed to explore children's online experiences. A non-random, stratified sample of 200 London school children aged 10- 13 participated in focus groups. Preliminary findings are also presented from unpublished ongoing PhD research, which seeks to explore sex offender behaviour online and the policing of the internet (Martellozzo, 2005 ongoing). The findings are discussed in the context of sex offender's use of the internet. This research indicates that children do have some basic knowledge about 'stranger danger' but are not necessarily applying these lessons to cyberspace. The children in this study had sufficient awareness to not give personal details to strangers on the internet, and would not arrange to meet them. However, they made a distinction between 'strangers' and 'virtual friends' and this is an important point. Preliminary findings also highlight the difficulty of policing the internet and serve to illustrate the manner in which the Sexual Offences Act 2003 is applied to internet sexual offending in practice.

Networked learning ten years on: the rise of the virtual graduate school

The aim of this paper is to reflect on how conceptions of networked learning have changed, particularly in relation to educational practices and uses of technology, that can nurture new ideas of networked learning to sustain multiple and diverse communities of practice in institutional settings. Our work is framed using two theoretical frameworks: Giddens's (1984) structuration theory and Callon & Latour's (1981) Actor Network Theory as critiqued by Fox (2005) in relation to networked learning. We use these frameworks to analyse and critique ideas of networked learning embodied in both cases. We investigate three questions: (a) the role of individual agency in the development of networked learning; (b) the impact of technological developments on approaches to supporting students within institutional infrastructures; and (c) designing networked learning to incorporate Web 2.0 practices that sustain multiple communities and foster engagement with knowledge in new ways. We use an interpretivist approach by drawing on experiential knowledge of the Masters programme in Networked Collaborative Learning and the decision making process of designing the virtual graduate schools. At this early stage, we have limited empirical data related to the student experience of networked learning in current and earlier projects. Our findings indicate that the use of two different theoretical frameworks provided an essential tool in illuminating, situating and informing the process of designing networked learning that involves supporting multiple and diverse communities of practice in institutional settings. These theoretical frameworks have also helped us to analyze our existing projects as case studies and to problematize and begin to understand the challenges we face in facilitating the participation of research students in networked learning communities of practice and the barriers to that participation. We have also found that this process of theorizing has given us a way of reconceptualizing communities of practice within research settings that have the potential to lead to new ideas of networked learning.

Four years on: a longitudinal study assessing the impact of a virtual community of practice

This paper explores the long term impact of a virtual learning community (VLC) from the perspective of community members and their employing organization. It argues that membership potentially has a significant impact on individual identities and careers, and that managed communities provide an important means for strategic workforce development. The study evaluates the impact of membership of a VLC over a four year period within the context of the theoretical frameworks of communities of practice and identity theory. The concept of boundary crossing is also explored in relation to VLCs. The paper considers the benefits to host organisations in supporting structured VLCs as a means of enabling workforce development and supporting change and innovation.

High level student autonomy in a virtual learning environment

This case study explores the experiences of a group of students (the authors) working as a tutor-less group (TLG) that developed during a web-based MEd programme. We describe the development and life cycle of the TLG, the experiences of the students and the effects on those who continued to work in a tutored environment. Members of the TLG demonstrated high levels of autonomy and group work. The relationship between the TLG and communities of practice is considered.

A importância da personagem virtual no contexto da animação 3D em tempo real

O desenvolvimento de personagens digitais tridimensionais1 na área da animação, a constante procura por soluções tecnológicas convincentes, aliado a uma estética própria, tem contribuído para o sucesso e afirmação da animação tridimensional, na indústria do entretenimento. Contudo, toda a obra que procura ou explora a vertente digital/3D, torna-se ‘vitima’ das limitações do render2 aplicado a uma sequência de imagens, devido ao aumento dos custos financeiros e humanos, assim como da influência e dificuldade implicadas no cumprimento dos objectivos e prazos. O tempo real tem assumido, cada vez mais, um papel predominante na indústria da animação interactiva. Com a evolução da tecnologia surgiu a necessidade de procurar a metodologia apropriada que sirva de alavanca para o desenvolvimento de animações 3D em tempo real, através de softwares open-source ou de baixo orçamento, para a redução de custos, que possibilite simultaneamente descartar qualquer dependência do render na animação 3D. O desenvolvimento de personagens em tempo real, possibilita o surgimento de uma nova abordagem: a interactividade na arte de animar. Esta possibilita a introdução de um vasto leque de novas aplicações e consequentemente, contribui para o aumento do interesse e curiosidade por parte do espectador. No entanto, a inserção, implementação e (ab)uso da tecnologia na área da animação, levanta questões atuais sobre qual o papel do animador. Esta dissertação procura analisar estes aspectos, dando apoio ao projecto de animação 3D em tempo real, denominado ‘PALCO’.

Virtual power producers integration into MASCEM

All over the world Distributed Generation is seen as a valuable help to get cleaner and more efficient electricity. Under this context distributed generators, owned by different decentralized players can provide a significant amount of the electricity generation. To get negotiation power and advantages of scale economy, these players can be aggregated giving place to a new concept: the Virtual Power Producer. Virtual Power Producers are multi-technology and multi-site heterogeneous entities. Virtual Power Producers should adopt organization and management methodologies so that they can make Distributed Generation a really profitable activity, able to participate in the market. In this paper we address the integration of Virtual Power Producers into an electricity market simulator –MASCEM – as a coalition of distributed producers.
