Social Media for Digital and Social Inclusion: Challenges for Information Society 2.0 Research & Policies

In this paper we reflect on how research and policies can and/or should help in the development of a sustainable participatory information society for all. More specifically, we aim to investigate critically how social media can entail both potential and pitfalls, especially with regard to the difficult relationship between digital and social inclusion. First of all, traditional information society policies are scrutinized. Furthermore, we point at the existence of digital inequalities and we reflect briefly on policy intervention on e-inclusion. In addition, we also evaluate the raise of social media. Finally, attention is given to the challenge of how research can contribute to the participation of all in the information society

What social media data mean for audience studies: a multidimensional investigation of Twitter use during a current affairs TV programme

Both practitioners and researchers embrace the increasing volume of digital data to measure and understand audiences. This study focuses on Twitter use during an eminent Belgian current affairs television (TV) programme to investigate how people talk about TV on Twitter. The main objective of the study is to understand how we can interpret these digital traces and, in extension, discuss its utility and value for audience studies. More specifically, we define two validity issues related to the use of social media data: that is, the technological bias of data analysis and the alleged objectivity of the data. These issues are addressed through the combination of Twitter data and user insights. In particular, we focus on interaction patterns and the content of Twitter messages in relation to TV content. We compliment these analyses with in-depth interviews with a selection of Twitter users. The results confirm the variations and complexities of the use of digital objects such as the @-sign and the hashtag. In addition, although Twitter messages are unobtrusive measures, they reflect performances in the sense that they entail interpretations as well as representations of the self and one's programme taste. Users predominantly feel the need to scrutinize the actions and utterances of politicians and experts. The use of irony and sarcasm exemplifies the playfulness and fun factor of these activities. To conclude, we elaborate on the results in relation to the validity issues we put forth and discuss methodological and epistemological concerns related to the use of social media data in audience studies

Measuring for Knowledge: A Data-Driven Research Approach for eGovernment

As ICT provide a lot of possibilities, high expectancies exist towards the electronic public service provision. All governments are increasingly establishing their e-strategies. However, eGovernment still faces many challenges as it continues to develop. The current status of electronic services delivery opens up a lot of questions, both for practitioners and researchers. Therefore, further progress of eGovernment needs a profound knowledge base. eGovernment policy has focused several years on bringing online public services and on benchmarking their availability and sophistication. Simultaneously, eGovernment measurement and monitoring activities are often based on the so-called supply-side benchmarking. Although this is important knowledge, it is under criticism because it lacks a user-centric viewpoint of eGovernment development. This article presents and discusses a bottom-up and data-driven approach about how research can help to manage (user-centric) eGovernment strategies. Based on statistical testing (techniques of structural equation modeling, SEM) of large-scale sample data from the Belgian government, the authors have investigated which relations do exist between contextual variables and the availability and/or satisfaction of electronic public services. By doing this, this manuscript presents an illustration of a data-driven approach in eGovernment monitoring and it explains how this can support and enrich the management and evaluation of eGovernment policy

The analog switch-off in a cable dominated television landscape. Implications for the transition to digital television in Flanders

Flanders will complete the migration from analog to digital terrestrial television by the end of 2008. Despite the cable dominated television landscape, the Flemish government is aiming at a smooth transition from analog to digital terrestrial television. Therefore, a multi-methodical study (quantitative survey and qualitative focus group interviews) has been set up by order of the Flemish government to understand the specific features and needs of analog antenna viewers and their expectations for the analog switch-off. The study shows that there are three distinctive types of analog antenna viewers. The results demonstrate that the antenna viewers are rather badly informed about the upcoming analog switch-off, which may lead to a negative attitude and may impede a smooth transition. Finally, antenna viewers seem to be rather conservative viewers: they wish to keep on watching the same television programs from the same channels. Moreover, digital terrestrial television is their preferred alternative

What We Think We Know About Cybersecurity: An Investigation of the Relationship between Perceived Knowledge, Internet Trust, and Protection Motivation in a Cybercrime Context

Individual internet users are commonly considered the weakest links in the cybersecurity chain. One reason for this is that they tend to be overoptimistic regarding their own online safety. To gain a better understanding of the cognitive processes involved in this assessment, the current study applies an extended version of the protection motivation theory. More specifically, this study includes perceived knowledge and internet trust to discover how these antecedents influence the threat and coping appraisal processes. Based on representative survey data collected from 967 respondents, we found that people who feel well-informed about online safety feel less vulnerable to cybercrime and are less inclined to take security measures. At the same time, feeling informed is associated with being more convinced of the severity of cybercrime. High levels of trust in the safety of the internet are linked to the feeling that one is less vulnerable to cybercrime and the perception that cybercrime is not a severe threat. Future interventions should remind internet users about their own perceived vulnerability and the risks that exist online while ensuring that internet users do not lose their trust in the internet and confidence in their own online knowledge

The effect of dietary non-starch polysaccharide level and bile acid supplementation on fat digestibility and the bile acid balance in rainbow trout (Oncorhynchus mykiss)

This study investigated in rainbow trout (Oncorhynchus mykiss) if dietary bile acid supplementation is effective in restoring hampered fat digestibility related to conditions that enhance fecal bile acid loss (i.e., high dietary non-starch polysaccharide (NSP) level and high feeding level). Four diets were formulated according to a two-by-two factorial design. A Low- and High-NSP level (0 vs. 160 g kg-1 inclusion of a NSP-rich ingredient mixture) and two bile acid supplementation levels (0 vs. 2 g kg-1 inclusion of sodium taurocholate) were tested. A contrast in feeding level (i.e., feed intake) was created by subsequently feeding fish restrictively (1.1% BW d-1) for four weeks and to satiation for three weeks. The apparent digestibility coefficient (ADC) of all nutrients was affected by feeding period (i.e., restricted vs. satiation feeding), but the effect was dependent on diet composition with the ADC decline between feeding periods being larger for the High-NSP diets. The ADC of all macronutrients decreased alongside dietary NSP level, but this decrease was much more pronounced for fat compared to starch and protein, especially during satiation feeding (6.7%). This large drop in fat ADC during satiation feeding of NSP-rich diets occurred alongside enhanced fecal bile acid loss and correlated with a negative bile acid balance. The correlation between the bile acid balance and fat ADC found during satiation feeding of diets without bile acid supplementation was not present in fish fed diets with bile acid supplementation. In contrast to fat ADC, the ADC of protein and starch were independent from bile acid supplementation. In conclusion, dietary bile acid supplementation is an effective way to remediate decreased fat ADC related to enhanced fecal bile acid loss in rainbow trout, but is not effective in improving protein and starch ADC.</p

With a little help from my friends: An analysis of the role of social support in digital inequalities

This article reports an empirical study on the composition and socio-economic background of social support networks and their moderating role in explaining digital inequalities. It conceptually draws upon and empirically reaffirms Van Dijk’s multiple access model, acknowledging motivational, material, skill and usage divides, while focussing on the under-researched issue of social support as indispensible source of social learning. Besides a small group of self-reliants, the results indicate a pattern of relatively socially disadvantaged domestic support receivers, characterized by lower digital resources. A second social support pattern points to a relatively socially advantaged non-domestic support receivers (i.e. friends/colleagues), high in digital resources. Drawing upon the concept of homophily in social networks, the results indicate a link between offline and online exclusion, perpetuating digital inequalities

Mogelijkheden voor zeecultuur in nieuwe getijdennatuur langs de Westerschelde

In dit rapport zijn de mogelijkheden in kaart gebracht voor de combinatie van nieuwe getijdennatuur met een of meer productiefuncties op de volgende locaties langs de Westerschelde: Braakmanpolder, Hellegatspolder, Serarendspolder, Molenpolder, Zimmermanpolder en de Hedwige-Prosperpolder. Overwegingen van zoutgehalte en waterkwaliteit leiden tot de conclusie dat met name de Braakmanpolder, maar ook de Hellegatspolder en de Serarendspolder geschikt gemaakt kunnen worden voor bovengenoemde combinatie. Kijkend naar de mogelijkheden van deze drie polders, dan heeft de Braakmanpolder als voormalig slenkgebied de meeste mogelijkheden
