Deliverable D4.4 User profile and contextual adaptation

This deliverable presents the methods employed in LinkedTV to create, update and formalise a semantic user model. In addition, the first approach on extraction of context and contextual features and its adaptation onto the semantic user profiles is presented

Deliverable D4.2 User profile schema and profile capturing

This deliverable presents methods employed in LinkedTV to create, update and formalise a semantic user model that will be used for concept and content filtering. It focuses on the ex-traction of lightweight and dense implicit knowledge about user preferences. This process includes the semantic interpretation of information that stem from the user’s interaction with the content, together with the estimation of the impact that pre-ferred concepts have for each specific interaction based on the type of transaction and the user’s physical reaction to the con-tent. User preferences are then updated based on their age, frequency of appearance and utility, while persistent associa-tions between preferences are learnt. This information evolves to a semantic user model that is made available for predictive inference about relevant concepts and content

Deliverable D4.1 Specification of user profiling and contextualisation

This deliverable presents a comprehensive research of past work in the field of capturing and interpreting user preferences and context and an overview of relevant digital media-specific techniques, aiming to provide insights and ideas for innovative context-aware user preference learning and to justify the user modelling strategies considered within LinkedTV’s WP4. Based on this research and a study over the specific technical and conceptual requirements of LinkedTV, a prototypical design for profiling and contextualizing user needs in a linked media environment is specified

'Detection of pemphigus desmoglein 1 and 3 autoantibodies and pemphigoid BP180 autoantibodies in saliva and comparison to serum values'

Although there is much literature on the detection of pemphigus and pemphigoid autoantibodies by enzyme-linked immunosorbent assay (ELISA) in serum, nothing is known about their presence in saliva. The aim of this study was to evaluate the salivary levels of these autoantibodies in pemphigus and pemphigoid patients. Autoantibodies against desmoglein3, desmoglein1, and BP180 were assayed, by ELISA, in serum and saliva samples of patients and healthy controls. The titres of autoantibodies against Dsg1/3 found in both serum and saliva of pemphigus patients showed a statistically significant correlation, suggesting that saliva may be a useful biological material for diagnostic purposes, in monitoring disease activity, as well as for the early detection of relapses. By contrast, the titres of autoantibodies against BP180 in the serum and saliva of bullous pemphigoid patients were not statistically related, and further study of the usefulness of the BP180 ELISA for saliva in this disease is needed. In addition, based on our results, the BP180 ELISA with a recombinant NC16a epitope failed to detect the autoantibodies against BP180 in the serum and saliva of mucous membrane pemphigoid patients

Tackling cyberbullying: Review of empirical evidence

The present literature review summarizes current knowledge on successful responses to cyberbullying. We differentiate between three different response domains: reducing risks, combatting the problem, and buffering negative impact. A systematic literature search was conducted yielding 36 relevant studies. Most of these report findings regarding general prevention strategies (e.g., anti-bullying policies or cybersafety strategies) and the use of coping strategies such as seeking support, reactions towards cyberbullies (retaliation or confronting), technical solutions and avoidant and emotion-focused strategies. Whilst a few studies reported on perceived success, very few studies measure the success of the strategies in relation to cyberbullying, its risks and outcomes. In summary, although there are a number of studies investigating responses to cyberbullying, there is a clear lack of evidence concerning the question “what are successful responses”?

Tackling cyberbullying : Review of empirical evidence regarding successful responses by students, parents, and schools

A summary of current knowledge on successful responses to cyberbullying differentiating between three different response domains: reducing risks, combatting the problem, and buffering negative impact. A systematic literature search yielded thirty-six relevant studies, most of which report findings regarding general prevention strategies (e.g., anti-bullying policies or cybersafety strategies) and the use of coping strategies such as seeking support, responding (retaliation or confronting), technical solutions, and avoidant and emotion-focussed strategies. Whilst a few studies report perceived success, very few measure the success of the strategies in relation to risks and outcomes. There is a clear lack of evidence concerning successful responses

Digital Divides revisited: What is new about divides and their research?

This article critically reviews well-established and recent trends in digital divides literature and research, bringing up new elements of divides and the related research and making recommendations about future research. First, it disentangles some aspects of the puzzling nature and ongoing importance of digital divides. It then discusses how the concept of digital divides has evolved over the last two decades and how research literature has examined it in the same period on the basis of different attempts at contextualisation. The article brings together theoretical and empirical insights and suggests that digital divides be revisited so as to illustrate the need for less linear and more properly contextualised approaches to the concept and phenomenon of digital divides where technology, society and politics will be jointed taken into consideration to explain divides. It specifically proposes that digital divides and their research be revisited so as to emphasise the critical role of socio-cultural and decision-making dynamics in structuring the adoption of ICT in both qualitative and quantitative terms. Thus, it argues that the web of cultural traits in a society, with their own gaps and disparities, as well as policy and regulation dynamics, are in a constant dialogue with technology, together influencing digital divides and entailing implications for other forms of divisions in society
