Virtuelle soziale Netzwerke gewinnen im Bereich des Human Resource Managements zunehmend an Bedeutung. In der vorliegenden Arbeit wird die Nutzbarkeit von virtuellen sozialen Netzwerken für die Personalauswahl untersucht. Beginnend mit einer Einführung in die virtuellen sozialen Netzwerke liegt der Schwerpunkt dieser Arbeit in der Prüfung verschiedener virtueller sozialer Netzwerke auf die Nutzbarkeit für die Personalauswahl. Hierbei wird das Hauptaugenmerk auf StudiVZ, ein virtuelles soziales Netzwerk mit der Zielgruppe Studenten, gelegt. Abschließend erfolgen eine Detailanalyse eines StudiVZProfils und eine Analyse der Aussagekraft über die Persönlichkeit des Nutzers.

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.

Cataloguing Kays is a university-run project intended to create a community web-archive to celebrate the history and public memory of Kay & Co Ltd of Worcester, a noted mailorder catalogue company which was, until 2006, the largest employer in Worcester. The Kays Archive, housed at UoW, is one of the most comprehensive archive collections of 20th century mail-order catalogues in the UK and has a strong local elevance. The catalogues provide a window into over 100 years of body image, social history, consumable goods, fashion and design. The Project Team created www.WorldofKays.org, an online, fully-searchable archive containing 1500 digitised images from the catalogues, 1920-2000. The website is intended to form a seed bed for international research, focussing in particular on the representation of body image and the way the catalogues represent the developing tropes of consumer lifestyle and aspiration. The images are enhanced by blog postings from or film and audio interviews with local residents and former Kays staff members, who recall how the goods were selected and presented; as well as the impact the mail-order industry had on shaping 20th century lifestyle and consumption. These interviews and blogs have been sourced through the Cataloguing Kays team’s outreach activity in the local, academic and online communities. From the outset, we, the Cataloguing Kays team, engaged with online communities through social media sites, Facebook and Twitter, and through specialist blogs and online forums, inviting comment and contributions. Through events for the general public and a programme of targeted community outreach work with Kays Heritage Group and support groups for Worcestershire’s young and adult carers, we have also collected filmed and audio reminiscence material as well as community art and poetry content for the website. Our academic conference, the Catalogue of Dreams, showcased both the website and the physical archive to the wider academic, cultural and heritage sectors, provoking lively debateand much interest from international scholars.

My paper will focus on the generative potential of categorising asynchronous discussion threads as one strategy for improving the quality of students’ learning in a blended learning module. The approach to categorisation is based on social network analysis using intuitively simple descriptors of message posting patterns e.g. passive facilitator, dominant facilitator, unresponsive star and formulaic discussion. The intention is to produce descriptively vivid illustrative examples of the categories and to begin to suggest affordances of the different participation patterns. Looking forward to the beginning of the next module, it is anticipated that discussion during the module of approaches to participating in asynchronous discussion will contribute to effective engagement patterns and deeper learning.

‘Making space for queer-identifying religious youth’ (2011–2013) is an Economic and Social Research Council (ESRC)-funded project, which seeks to shed light on youth cultures, queer community and religiosity. While non-heterosexuality is often associated with secularism, and some sources cast religion as automatically negative or harmful to the realisation of lesbian, gay, bisexual and transgender (LGBT) identity (or ‘coming out’), we explore how queer Christian youth negotiate sexual–religious identities. There is a dearth of studies on queer religious youth, yet an emerging and continuing interest in the role of digital technologies for the identities of young people. Based on interviews with 38 LGBT, ‘religious’ young people, this article examines Facebook, as well as wider social networking sites and the online environment and communities. Engaging with the key concept of ‘online embodiment’, this article takes a closer analysis of embodiment, emotion and temporality to approach the role of Facebook in the lives of queer religious youth. Furthermore, it explores the methodological dilemmas evoked by the presence of Facebook in qualitative research with specific groups of young people.

At the core of this paper is a psychosocial inquiry into the Marxist concept of alienation and its applications to the field of digital labour. Following a brief review of different theoretical works on alienation, it looks into its recent conceptualisations and applications to the study of online social networking sites. Finally, the authors offer suggestions on how to extend and render more complex these recent approaches through in-depth analyses of Facebook posts that exemplify how alienation is experienced, articulated, and expressed online. For this perspective, the article draws on Rahel Jaeggi’s (2005) reassessment of alienation, as well as the depth-hermeneutic method of “scenic understanding” developed by Alfred Lorenzer (e.g. 1970; 1986).

The use of perceptual inputs is an emerging area within HCI that suggests a developing Perceptual User Interface (PUI) that may prove advantageous for those involved in mobile serious games and immersive social network environments. Since there are a large variety of input devices, software platforms, possible interactions, and myriad ways to combine all of the above elements in pursuit of a PUI, we propose in this paper a basic experimental framework that will be able to standardize study of the wide range of interactive applications for testing efficacy in learning or information retrieval and also suggest improvements to emerging PUIs by enabling quick iteration. This rapid iteration will start to define a targeted range of interactions that will be intuitive and comfortable as perceptual inputs, and enhance learning and information retention in comparison to traditional GUI systems. The work focuses on the planning of the technical development of two scenarios, and the first steps in developing a framework to evaluate these and other PUIs for efficacy and pedagogy.

Urban Computing (UrC) provides users with the situation-proper information by considering context of users, devices, and social and physical environment in urban life. With social network services, UrC makes it possible for people with common interests to organize a virtual-society through exchange of context information among them. In these cases, people and personal devices are vulnerable to fake and misleading context information which is transferred from unauthorized and unauthenticated servers by attackers. So called smart devices which run automatically on some context events are more vulnerable if they are not prepared for attacks. In this paper, we illustrate some UrC service scenarios, and show important context information, possible threats, protection method, and secure context management for people.

A dissertação que ora apresentamos é um requisito para a obtenção do grau de mestre em Gestão Estratégica das Relações Públicas, pelo Instituto Politécnico de Lisboa - Escola Superior de Comunicação Social. Intitulado ‘O Uso que os Partidos Políticos Portugueses fazem do Facebook’, este estudo foi desenvolvido para tentarmos analisar e perceber o que os partidos políticos comunicam pelas suas páginas oficiais e nacionais na maior rede social. Inserido num contexto altamente relacional, ideológico e informacional, num mundo global em constantes mutações, que papel dão as organizações políticas à ferramenta de comunicação que se tornou o Facebook? Dos resultados obtidos, percebemos que dos seis partidos políticos portugueses com assento parlamentar – PSD, PS, CDS-PP, PCP, BE e PEV – nem todos detinham páginas oficiais e nacionais no Facebook, sendo que aqueles que as detêm ainda não retiram total partido das potencialidades da ferramenta de comunicação directa, imediata e interactiva que é a rede social. Apesar do transversal reconhecimento da sua importância, os partidos portugueses relegam a importância da criação de relações duradouras com o público através do Facebook.
