i* is one of the most popular modelling languages in Requirements Engineering. i* models are meant to support communication between technical and non-technical stakeholders about the goals of the future system. Recent research has established that the effectiveness of model mediated communication heavily depends on the visual syntax of the modelling language. A number of flaws in the visual syntax of i* have been uncovered and possible improvements have been suggested. Producing effective visual notations is a complex task that requires taking into account various interacting quality criteria. In this paper, we focus on one of those criteria: Semantic Transparency, that is, the ability of notation symbols to suggest their meaning. Complementarily to previous research, we take an empirical approach. We give a preview of a series of experiments designed to identify a new symbol set for i* and to evaluate its semantic transparency. The reported work is an important milestone on the path towards cognitively effective requirements modelling notations. Although it does not solve all the problems in the i* notation, it illustrates the usefulness of an empirical approach to visual syntax definition. This approach can later be transposed to other quality criteria and other notations. [less ▲]

The Available Routing Construct (ARC), recently proposed at IETF, provides a promising model for achieving highly reliable routing in large-scale networks. Among its features, ARC offers multi-path routing by design. In the present work, we introduced ARC for the first time to the research community. Then, we showed, by means of simulation results, how ARC over-performs classical multi-path routing algorithms, by building disjoint multiple paths without extra-cost due to new route computation.

Recent trends in the perception of labour and employment (Bourhis & Wils, 2001; Cultiaux & Vendramin, 2010; De Witte, Halman & Gelissen, 2004) suggest changes in the perception of unemployment and absence of work. Some years ago, Galland (2000) put forward the hypothesis that the statistical increase of unemployment could lead to its relative normalisation. We thus hypothesise jobless people, fighting the negative effects of unemployment, consider this situation as normal and unavoidable, and attribute it to external, non-controllable factors. Then, to a better understanding of this phenomenon, the present study examines the links between normalisation and various psychological and socio-professional dimensions. 205 French unemployed people took 5 questionnaires: the French version of coping scale WCC-R (Way of Coping Checklist - Revised, Cousson, 1996), a scale of locus of control (Meyers & Houssemand, 2005), one of centrality of work (Gringas & Chagnon, 1997), some items allow the definition of the professional trajectories and career path (Dupuy, Le Blanc, & Mégemont, 2006) and a scale of unemployment normalisation (Pignault & Houssemand, 2013). Results showed external locus of control (r=.36, p<.001) and emotion-focused coping style (r=.43, p<.001) are positively correlated with unemployment normalisation. But the participants’ career path did not influence their representation of the unemployment. This study confirms the hypothesis that the unemployment normalisation depends on some psychological dimensions. Unemployment services could use it for predicting the normalisation level and fighting better against the jobless situation. [less ▲]

Nowadays, a significant portion of the total energy consumption is attributed to the buildings sector. In order to save energy and protect the environment, energy consumption in buildings must be more efficient. At the same time, buildings should offer the same (if not more) comfort to their occupants. Consequently, modern buildings have been equipped with various sensors and actuators and interconnected control systems to meet occupants’ requirements. Unfortunately, so far, Building Automation Systems data have not been well-exploited due to technical and cost limitations. Yet, it can be exceptionally beneficial to take full advantage of the data flowing inside buildings in order to diagnose issues, explore solutions and improve occupant-building interactions. This paper presents a plug-and-play and holistic data mining framework named PHoliData for smart buildings to collect, store, visualize and mine useful information and domain knowledge from data in smart buildings. PHoliData allows non technical experts to easily explore and understand their buildings with minimum IT support. An architecture of this framework has been introduced and a prototype has been implemented and tested against real-world settings. Discussions with industry experts have suggested the system to be extremely helpful for understanding buildings, since it can provide hints about energy efficiency improvements. Finally, extensive experiments have demonstrated the feasibility of such a framework in practice and its advantage and potential for buildings operators. [less ▲]

"We provide micro-interactional analysis of a series of motion gaming sessions (Gregersen, 2011) with a focus on response cries (Goffman, 1978, 1981). We use Conversation Analysis (CA) to analyze interactions in their situatedness and moment-by-moment unfolding (Schegloff, Sacks and Jefferson, 1977). We bring evidence that, although speakers sometimes communicate by means of non-lexicalized, subvocalized, interjections and vocalizations, they still manage to understand and coordinate each other. Extracts are taken from two corpora. One is the (2010) SISS-Corpus, consisting of eight hours of video-recordings of groups of teenage students filmed in their school while playing digital games on a Nintendo Wii console. Participants speak their L1 and select different socio-stratic varieties (Tempesta, 1995; 2000; 2005) of Italian. The second corpus (2009-2012) Multi-Wii- consists of eleven hours of video-recordings of groups of multilingual speakers recorded at University of Luxembourg. Participants select English, French and German (L2) as lingua franca. Data show that response cries develop into an ‘intersubjective’ (Schegloff, 1991; Aarsand and Aronsson, 2009) language, and constitute a mutually understandable form of interaction shared by participants. In an evolutionary and developmental perspective, response cries may be thought of as a physiological, vocalized protolanguage of emotions, speakers use socially, for indexical purposes (Heritage and Raymond, 2005); to express stance (Heritage, 2012), and co-construct emotion as an interactional achievement (Schegloff, 1988). The contribution discusses the process by which cognitive –emotional- states are brought to life via embodiment in interaction (Goodwin, 2011) through language and other physiological evolutions like gestures and facial kinetics (Birdwhistell, 1970)."

This contribution examines how the diverse language resources that teachers and learners bring to the classroom can support the process of language learning. It draws on a range of linguistic ethnographic data collected at a French language course that was attended mostly by Syrian and Iraqi refugees in Luxembourg. Drawing on the analysis of multilingual interactional practices, the article sheds light on some of the opportunities for learning that emerged as a result of translation, translanguaging and receptive multilingualism. It discusses the relevance of these practices for building a repertoire of resources that enables forced migrants to communicate in multilingual contexts such as Luxembourg. [less ▲]

Sociology’s knowledge-making practices consist primarily in cutting social reality (realities) into distinct, but overlapping and abstract entities, which are variously juxtaposed and micro-/macrofied depending on the underlying theoretical assumptions as they are “worked” by researchers. (Social) research as an ongoing process of cutting abstract entities is thus producing an almost infinite plurality of scales. In this sense, it is not surprising that we periodically assist at the emergence of new “turns”, from the cognitive to the material and the linguistic or emotional. This group addresses persons who are interested in working on how persons-as-researchers-and-theorists-cut-and-invent-social-reality. For the organizers, the work of Andrew Abbott as well as Marilyn Strathern has inspired the following questions: How do social theories cut, invent and try to covenant social reality? How is social reality cut, invented and covenanted in so-called professional contexts? How is social reality cut, invented and covenanted by methods of social research? [less ▲]

Isogeometric analysis relies on the use of the same basis functions as employed in Computer Aided Design (CAD). This offers the possibility to facilitate design and optimisation. The previous course “Isogeometric methods for numerical simulation” held in 2013 had the aim to give an introduction to isogeometric analysis, its advantages, drawbacks and to the range of its applications. The aim of the proposed new course will be different. The focus will be more on the connection of simulation to CAD systems and how CAD data can be used directly for simulation, leading to a seamless integration. An overview of recent advances and applications will be also presented. The course will start with an introduction to NURBS and their use in describing geometry and in simulation. This will be followed by lectures from a CAD vendor describing the current state of development. Currently available connections to simulation software will also be discussed. Next the use of NURBS for 3D structural analysis, structural optimisation and damage tolerance assessment will be presented, including such advanced topics as the treatment of discontinuities and real-time solvers. It will also be discussed when it might be advantageous to decouple the boundary discretisation from the field variable discretisation, in particular in shape optimisation. Isogeometric methods for the analysis of beam and shell structures, including shape optimisation and fluid structure interaction, will be presented. Lectures on the mathematical and algorithmic foundations of analysis-suitable geometry will follow. This includes an introduction to T-splines and multilevel spline schemes such as hierarchical B- splines. Common analysis-suitable spline algorithms will be presented in the context of Bézier extraction and projection as well as its application as a foundation for integrated engineering design and analysis. An important aspect of analysis-suitable geometry is the ability to locally adapt the smooth spline basis. Several common refinement algorithms will be reviewed as well as their application in several demanding areas of application. The emerging area of weak geometry will be introduced as well as its application to the rapid construction of complex structural assemblies. With the rapid development of isogeometric analysis in recent years, there is an urgent need for volumetric parameterization such as volumetric T-spline model construction. Several volumetric T- spline modeling techniques, that were developed in recent years will be presented. They include converting any quad/ hex meshes to standard and rational T-splines, polycube-based parametric mapping, feature preservation using eigenfunctions, Boolean operations and skeletons, truncated hierarchical Catmull-Clark subdivision, weighted T-splines, conformal T-spline modeling, as well as incorporating T-splines into commercial CAD and FEA software, will be presented. The target audience will be engineers, interested in simulation, software developers and researchers. [less ▲]
