La crise économique et financière que nous traversons depuis deux ans ne diffère en rien de celles que notre monde a connues au cours de sa longue histoire (Malkiel, 2000). De tels ajustements sont nécessaires chaque fois que notre système économique doit s’adapter à des changements technologiques majeurs. La longueur atypique de cette crise et son ampleur - plusieurs milliers de milliards de dollars de capitalisation boursière perdus – soulignent toutefois l’importance exceptionnelle des ajustements qu’engendrent l’adoption et la diffusion de ces technologies nouvelles.

Using a sociological approach, we show how Tunisians of the diaspora take advantage of Internet to keep themselves involved and informed and to denounce what they consider as unjust in their native country. We describe the style of critical speech preferred by these activist Internet users and the type of public sphere they claim. We study the activist paths of some of them and analyse their relationships with Internet users living in Tunisia. While they are initially less likely to openly denounce (use of indirect criticism) the authoritarian regime, we illustrate how these Internet users in Tunisia come to play an increasingly important role in this new space of contestation.

One challenge in teaching sustainability results from the expertise being distributed in various universities. At the same time society would not require so many experts focused on sustainability that corresponding purely sustainability-oriented curricula should be offered in a majority of universities. Thus sustainability aspects have to be integrated into existing curricula e.g. in chemical engineering studies. To offer sufficiently high-level courses or teaching content, one way is to share modules dealing with sustainability aspects. The idea to share teaching capabilities on a national or international level is not new, some examples are sustainicum.at, bioenergytrain.eu. While these approaches address the topic of sustainability with a relatively wide variety of facets, it is difficult to see, how a coherent picture can be obtained and transferred in education to students and the interested public. While this is so, already regarding the most basic element of the versatile toolbox of chemical engineering, namely setting up and solving simple balances, leads to significant insights and especially a fundamental understanding on the basic interplay of at least some of the major drivers. These are – besides increasing world population, which is the main driver – the increasing energy consumption, the limited land area for food and bioenergy production, the finite size even of the atmosphere leading to an increase in CO2 concentration and climate change, to name just a few. All of these aspects refer to limited resources for which balances can be set up and solved. The balances have the advantage that they are so simple that everybody can assess their validity and implications. The experience with working out a corresponding teaching module will be presented exemplarily. To facilitate delivering the aspects to students and the interested public the teaching material including a full manuscript and power-point slides have been worked out and are supplied at sustainicum.at. To allow easy access to the content of this teaching material also corresponding lectures have been recorded and are made publicly available through YouTube. The technical boundary conditions, which were found to be quite optimal as compared to other public lectures available on the internet, will be presented. The teaching material has in the past also been used for a variety of own presentations with the aim to deliver the basic understanding to an interested public, including public conference series or school classes. From these various experiences conclusions are drawn which will be presented.

Since the nineties, the Internet has seen an impressive growth, in terms of users, intermediate systems (such as routers), autonomous systems, or applications. In parallel to this growth, the research community has been looking for obtaining and modeling the Internet topology, i.e., how the various elements of the network interconnect between themselves. An impressive amount of work has been done regarding how to collect data and how to analyse and model it. This chapter reviews main approaches for gathering Internet topology data. We first focus on hop limited probing, i.e., traceroute-like probing. We review large-scale tracerouting projects and discuss traceroute limitations and how they are mitigated by new techniques or extensions. Hop limited probing can reveal an IP interface vision of the Internet. We next focus on techniques for aggregating several IP interfaces of a given router into a single identifier. This leads to a router level vision of the topology. The aggregation can be done through a process called alias resolution. We also review a technique based on IGMP probing that silently collect all multicast interfaces of a router into a single probe. We next refine the router level topology by adding subnet information. We finish this chapter by discussing the AS level topology, in particular the relationships between ASes and the induced hierarchy. [less ▲]

Since the beginning of the nineties, the internet has undergone impres- sive growth. This growth can be appreciated in terms of the equipment, such as routers and links, that has been added, as well as in the numbers of users and the value of commerce that it supports. In parallel to this expansion, over the past decade the networking research community has shown a growing interest in discovering and analyzing the internet topology. Some researchers have developed tools for gathering network topology data while others have tried to understand and model the internet’s properties. These efforts have brought us to a crucial juncture for toplogy measurement infrastructures: while, previously, these were both small (in terms of number of measurement points) and monolithic, we are starting to see the deployment of large-scale distributed systems composed of hundreds or thousands of monitors. As we look forward to this next generation of systems, we take stock of what has been achieved so far. In this survey, we discuss past and current mechanisms for discovering the internet topology at various levels: the IP interface, the router, the AS, and the PoP level. In addition to discovery techniques, we provide insights into some of the well- known properties of the internet topology. [less ▲]

Despite the numerous health benefits, population physical activity (PA) levels are low and decline with age. In Belgium, people older than 60 years will represent more than a third of the entire population in 2050, with some major implications in terms of public health cost. Faced with this issue, innovative interventions to promote PA in older adults are of major interest. The Internet holds potential for delivering effective PA interventions. Besides, older adults are the largest-growing group of Internet users. Therefore, the main purpose of this study was to explore the opinion of older adults about Internet-based PA promotion. First, 75 older adults (73.75 ± 5.77 years) fulfilled a questionnaire about their PA stage of change, motivation about PA and opinion about several elements that could be included in an Internet-based PA website. Then, they were asked to participate in an unique session of “home exercising”. Finally, in a subsequent interview, they had to give their opinion about the inclusion of this kind of session in an Internet-based PA website. Only 48% of the participants met the official guidelines for PA. A regular access to the Internet was observed for 57.3% of the participants, with a significantly higher access for the younger ones (p = .014). Based on a 4-point Likert scale, the most popular topics for an Internet-based intervention were “PA social forum” (3.3/4), “PA local opportunities” (3.2/4), “PA local agenda” (3.1/4), “Benefits of PA” (3.1/4) and “PA programs” (3.1/4). According to the participants, the inclusion of “home exercising” in an internet-based PA website would be appreciated (7.85/10), adapted (8.78/10) and likely to be self-implemented at home (6.96/10). Findings suggest that an internet-based PA promotion may be acceptable for older people. Social and neighborhood environment elements appear to be essential in order to support the motivation for a regular PA practice. [less ▲]

OBJECTIVES: To establish the level of observer variation for the current ATS/ERS/JRS/ALAT criteria for a diagnosis of usual interstitial pneumonia (UIP) on CT among a large group of thoracic radiologists of varying levels of experience. MATERIALS AND METHODS: 112 observers (96 of whom were thoracic radiologists) categorised CTs of 150 consecutive patients with fibrotic lung disease using the ATS/ERS/JRS/ALAT CT criteria for a UIP pattern (3 categories--UIP, possibly UIP and inconsistent with UIP). The presence of honeycombing, traction bronchiectasis and emphysema was also scored using a 3-point scale (definitely present, possibly present, absent). Observer agreement for the UIP categorisation and for the 3 CT patterns in the entAUe observer group and in subgroups stratified by observer experience, were evaluated. RESULTS: Interobserver agreement across the diagnosis category scores among the 112 observers was moderate, ranging from 0.48 (IQR 0.18) for general radiologists to 0.52 (IQR 0.20) for thoracic radiologists of 10-20 years' experience. A binary score for UIP versus possible or inconsistent with UIP was examined. Observer agreement for this binary score was only moderate. No significant differences in agreement levels were identified when the CTs were stratified according to multidisciplinary team (MDT) diagnosis or patient age or when observers were categorised according to experience. Observer agreement for each of honeycombing, traction bronchiectasis and emphysema were 0.59+/-0.12, 0.42+/-0.15 and 0.43+/-0.18, respectively. CONCLUSIONS: Interobserver agreement for the current ATS/ERS/JRS/ALAT CT criteria for UIP is only moderate among thoracic radiologists, AUrespective of theAU experience, and did not vary with patient age or the MDT diagnosis.
