A common assertion is that online forums are not representative of the general public opinion but would reflect the behaviour and opinions of frustrated and extremist citizens. The objective of this paper is to empirically test this assertion by looking at the online debates about the referendum on the question of whether resident foreigners should under certain conditions (that will be specified) be allowed to vote for the national elections in Luxembourg. In order to measure the opinions emerging from the online forums, the author has gathered the comments of a selection of the most read and active campaign forums (more than 50 comments) and has coded them to determine if they are in favour or against the extension of voting right to foreigners. The representativeness of the online forms is evaluated by comparing these results with, on the one hand, the referendum outcome and, on the other hand, the data of a representative post-referendum survey that compares the opinions of people who were active in the online forum with the ones of passive users (reader but no posting) and non-users.

Too often online surveys are conducted without adequate attention to implementation details. One example is the frequent use of the forced answering option, which forces the respondent to answer each question in order to proceed through the questionnaire. The avoidance of missing data is often the idea behind the use of the forced answering option. There has been a tremendous increase in the use of this option; however, the inquirers are often not aware of possible consequences. Currently, only a few studies have researched the impact of forced answering on different quality parameters (e.g. dropouts, item nonresponse), with inconsistent results. To date no study has systematically examined effects of forced answering formats on answer quality. Given the rise in the popularity of online surveys in general and the frequent use of the forced answering option in particular, the impact of forced answering on data quality needs to be addressed. Our study assesses the consequences of the implementation of the forced answering option on dropouts as well as on answer quality. Our major hypothesis is that forcing respondents to answer will cause reactance, which in turn will decrease answer quality and increase dropout rates. To analyse the consequences of the implementation of forced answering option on response behaviour, we use split-ballot-field-experiments. We already conducted two studies (n=1056 & n=615) with differing experimental conditions and a third is ongoing. To determine answer quality, we use instructed response items, self-report for faking and other self-reports. Our results show a significant increase in dropouts and higher percentages of fakers under the forced answering condition. Both can be interpreted as reactance behavior arising from the force to answer each question in this condition. So far, no study has systematically examined effects of forced answering formats on answer quality. Our Paper address this issue. [less ▲]

German number word system inverts units and tens compared to the Arabic notation. This is not the case in French, which is more transparent regarding the Arabic number code. Evidence indicates that the linguistic structure of number words can facilitate or impede numerical development (Zuber, Pixner, & Moeller, 2009). Moreover, in transcoding tasks more mistakes are made in non-transparent compared to transparent languages (Imbo, Vanden Bulcke, De Brauwer, & Fias, 2014). We used a new paradigm of transcoding task in which 28 French-speaking (FR) and 19 German-speaking (GE) 4th grade children had to listen two digits numbers. The new thing was that we manipulate the order of appearance of the units and the tens of the number in three conditions: Units-First (UF), Tens-First (TF) and Simultaneous (S). Then, the subjects had to choose the heard number among four numbers presented on the computer screen. Results sows that GE are globally slower than FR (F(1,45) = 3.95, p = .053). The largest difference was observed for the TF: (t(45) = -3.729, p = .001). Moreover, when the order of the number appearance was congruent with the number word system, the transcoding was faster in both languages. For GE the S condition was slower than TF condition (F(2,36) = 6.918, p = .008) and than UF condition (F(2,36) = 6.918, p = .003.). For FR, the TF was faster than S (F(2,54) = 69.419, p < .001) and UF (F(2,54) = 69.419, p < .001). All these data indicate that language structure qualitatively impacts on basic numerical tasks.

Mutation testing is a well-known testing technique which combines error injection and unit testing. Mutation testing is an approach that tests the efficiency of the test suite, but in doing so it also allows to achieve a better understanding of the System Under Test (SUT). This work extends mutation testing techniques to ontologies expressed in the OWL language. Mutation operators on OWL ontologies change the semantics of the ontology, regardless of the syntax in which it is expressed. Mutation testing can assist the designer in the identification of potential flaws and in the maintenance of the ontology. [less ▲]

Would you buy flowers at the petrol station? This presentation examines the petrol station trope and its oscillation between site (a space where people interact) and sign or cultural signifier. It presents the result of the empirical study carried out in the interdisciplinary research project 'IDENT2 - Strategies of Regionalisation: Constructing Identity Across Borders', and examines the transformation of the physical 'petrol station' into a 'code' that is actively used as a qualifier in popular culture and in everyday life situations.

Let M be the Simpson moduli space of semistable sheaves on the projective plane with fixed linear Hilbert polynomial P(m)=dm+c. A generic sheaf in M is a vector bundle on its Fitting support, which is a planar projective curve of degree d. The sheaves that are not vector bundles on their support constitute a closed subvariety M' in M. We study the geometry of M' in the case of Hilbert polynomials dm-1 (for d bigger than 3) and demonstrate that M' is a singular variety of codimension 2 in M. We speculate on how the question we study is related to recompactifying of the Simpson moduli spaces by vector bundles. [less ▲]

Sustainable development remains a powerful concept across European and global fields of policy-making. Spurred by the all-encompassing threat of climate change, the rhetoric of a great transformation successfully occupies current policy and practice. However, in contrast to the doom and gloom predictions, and in stark contrast to the sheer magnitude of the challenge of dealing with such complex set of problems, recent policy ideas and recipes seem trivial, and overly rationalised and optimistic. With respect to this, there are two interrelated issues that will be explored in this session. First, much of this new rationality of sustainability moults into popular labels such as ‘green’ or ‘smart’ where the city is the primary setting. This search for practical solutions in the city is further buttressed by the ‘sustainability business’ and associated green-washing practices that have emerged, as well as a variety of tools to assess, monitor, evaluate, and certify sustainability initiatives (indicators, metrics, and planning orthodoxies such as density, integrated, or holistic planning) that have become standard practice. Scholars have been active to identify the pitfalls here: Elgert & Krueger (2012) discussed the epistemology of metrics; Wiig (2015) interrogated the corporate strategy of a multi such as IBM behind ‘smart city’; Angelo & Wachsmuth (2015) criticised ‘methodological cityism’ in political ecology; Purcell (2006) showed the limits to localism; Mössner (2013) exposed socio-political limits of green cities. These criticisms highlight that there is something else to explore beyond current notions of sustainability. In this session, we explore further critiques of existing attempts, as well as conceptions of sustainability that embrace more contemporary imaginaries of urban geographies. These include critical reflections on super-optimist projects such as transition towns, or green cities (e.g. localism, methodological city-ism, green-washing in urban marketing), and thoughts on the disparity between the normative of sustainable development and current policy realities (How has this disparity changed? How is it produced? What lays outside the current lens? How has green urbanism changed over time and across places?). The second issue relates to expectations of knowledge proliferation in academia, as research communities are increasingly embedded in contradictory settings, expected to provide results and not problems, to be frank but constructive, and moreover, to be elite, excellent, income-generating as well as critical. In this respect, there is thus good reason to analyse the research-policy nexus, as Woods & Gardner (2011), Pain (2006), and Beaumont et al. (2005) have explored, examine the construction of knowledge claims as Rydin (2007) has explained, and rework some considerations with regards to rationalist modes in sustainable development and emerging sustainability modernities. We thus also want to interrogate the tensions between the construction of positivist sustainability on the one hand, and the position of the critical researcher on the other hand – the treading of the fine line between Dennis Judd’s (2005) claim that urban scholars tend to assume that “everything is always going to hell” (Judd 2005) and Elbert Hubbard’s classical “positive anything is better than negative nothing” (Hawthorne 1902). Concrete questions addressed here are: Who is producing claims to knowledge in practices of sustainable development urbanism? What are the possibilities and limitations for researchers to balance constructive interventionism with realistic limits of sustainable development and all its complexities, messy politics, wicked problems that are observed in human geography? How is it possible to pursue state-led contract work while maintaining critical integrity? What are relevant reflections the ontology, methodology and ethics of applied SD research practice?

Cette contribution a pour objet d'analyser l'importance des frontières nationales pour les identités spatiales dans des régions transfrontalières. À cet effet, elle élaborera un modèle d'analyse pluridimensionnel permettant d'étudier les identités et, à l'exemple de la Grande Région SaarLorLux, posera la question de savoir comment les habitants se représentent l'espace et organisent leur pratiques de vie quotidienne sur le plan spatial. Par ailleurs, l'analyse révèlera des projections spatiales dans le discours politique et montrera dans quelle mesure celles-ci constituent une base de processus identitaires. La contribution démontre que, malgré des imbrications transfrontalières, les frontières nationales jouent un rôle important dans les processus de projection et d'appropriation identitaires des habitants de la Grande Région SaarLorLux, mais pas nécessairement en tant que catégories rigides.
