Many studies focussing on spelling in French and German languages show that, even by the end of the primary school, pupils have difficulties to encode morphosyntactic information in their writing. Particularly problematic are, for instance, capitalisation of nouns in German (Betzel 2014) or plural markers in French (Fayol et al. 2006), because they are inaudible and require knowledge that goes beyond simple phoneme-grapheme correspondences. Our paper presents how multilingual learners deal with silent morphosyntactic markers in French and German and shows the effects of an intervention training on children's spelling performance. In total our study included 228 multilingual fifth graders (mean age 11 years) with four years instruction in German and two years instruction in French. They were assigned to an intervention (n=137) and to a control group (n=91) based on the results of a spelling test in French and German. This was done by creating performance groups that were, in a second step, attributed to one of the experimental groups taking their performance into account (quasi-randomised procedure). The French test consisted of three word categories of different difficulty (nouns, verbs, adjectives). For adjectives only, position (pre- vs. post-nominal) was also manipulated. The German test focussed on three lexical-semantic characteristics (concrete nouns, abstract nouns, nominalizations) and four syntactical positions (determinant+noun, determinant+adjective+noun, adjective+noun, noun) frequent words and pseudo-words. Additionally, word frequency was manipulated within each language (frequent words vs. pseudowords). These difficulty levels have been based on the literature published on monolingual learners (French: Totereau et al. (2014), German: Funke (2005); Guenther (2007); Betzel (2014)). The children participated in 12 intervention sessions of 20 minutes each (six in German and six in French, the order was counterbalanced). Children of the intervention group were trained to improve their morphosyntactic awareness and thus spelling performance of French plurals and German capitalization. The control group received the same amount of language input than the intervention group, but they were trained on another aspect of language i.e. listening comprehension. Results from the pre-test show that multilingual children acquiring German and French show similar difficulty patterns as German or French monolinguals. The post-test shows that the intervention group improved significantly in both their German and French spelling in comparison to the control group in all word and pseudo-word categories and positions. The intervention group's performance increased especially on pseudo-words, indicating that the training had an effect on children's spelling according to syntactic regularities. The study results are specifically important to better understand the learning processes of morphosyntactic spelling in primary school. The implications on the teaching methods will be discussed.

In der Schweiz sind zum 1. Januar 2008 die geänderten Artikel des Obligationenrechts (OR) zur Abschlussprüfung (sog. ordentliche Revision) in Kraft getreten. Ein Ziel der Reform ist es gewesen, die Qualität der ordentlichen Revision zu erhöhen. Ansatzpunkte waren insbesondere die Verbesserung der Kommunikation der Revisionsstelle mit dem Verwaltungsrat (VR) durch die Einführung des sog. umfassenden Berichts und die Erweiterung des Prüfungsumfangs um die Prüfung der Existenz des Internen Kontrollsystems (IKS). Der vorliegende Beitrag adressiert die Unsicherheiten der Revisionsstellen beim umfassenden Bericht. Ziel ist es, erstmalig und in einer breitangelegten Befragung von VR- und GL-Mitgliedern ihre Zufriedenheit mit dem umfassenden Bericht zu erheben. Die Ergebnisse der explorativen Studie sollen den Wirtschaftsprüfungsgesellschaften Verbesserungspotenziale hinsichtlich ihrer Berichterstattung aufzeigen und Ansatzpunkte für eine „passgenaue” Berichterstattung liefern.

The number of foreigners living in Luxembourg is still rising and represents today about 48% of the inhabitants. This study focuses on the description and mapping of the place of residence for the different nationalities living in Luxembourg. It seeks to underline differences through indicators built from the 2011 census data. We focus on the territorial distribution of the different nationalities by taking into account the urban structure and distance to jobs. If differences according to nationalities in the residential behavior of households can be empirically identified they may raise issues of spatial equity and (un)equal accessibility to job market. We analyse whether the geographic location of different nationalities in Luxembourg is linked to urbanisation level, the distance to the “poles d´emploi” or general accessibility to jobs. [less ▲]

The level of industry-academia collaboration (IAC) in software engineering in general and in software testing in particular is quite low. Many researchers and practitioners are not collaborating with the “other side” to solve industrial problems. To shed light on the above issue and to characterize precisely what industry wants from academia in software testing, we solicited practitioners’ opinions on their challenges in different testing activities and also the particularly relevant topics that they want the research community to work on. This short paper aims to draw the community’s attention to the important issue of strengthening IAC with the hope of more IAC in software testing in the areas of most importance to the industry.

Background: Choosing the right software test automation tool is not trivial, and recent industrial surveys indicate lack of right tools as the main obstacle to test automation. Aim: In this paper, we study how practitioners tackle the problem of choosing the right test automation tool. Method: We synthesize the “voice” of the practitioners with a grey literature review originating from 53 different companies. The industry experts behind the sources had roles such as “Software Test Automation Architect”, and “Principal Software Engineer”. Results: Common consensus about the important criteria exists but those are not applied systematically. We summarize the scattered steps from individual sources by presenting a comprehensive process for tool evaluation with 12 steps and a total of 14 different criteria for choosing the right tool. Conclusions: The practitioners tend to have general interest in and be influenced by related grey literature as about 78% of our sources had at least 20 backlinks (a reference comparable to a citation) while the variation was between 3 and 759 backlinks. There is a plethora of different software testing tools available, yet the practitioners seem to prefer and adopt the widely known and used tools. The study helps to identify the potential pitfalls of existing processes and opportunities for comprehensive tool evaluation. [less ▲]

Research collaboration between industry and academia supports improvement and innovation in industry and helps to ensure industrial relevance in academic research. However, many researchers and practitioners believe that the level of joint industry-academia collaboration (IAC) in software engineering (SE) research is still relatively low, compared to the amount of activity in each of the two communities. The goal of the empirical study reported in this paper is to exploratory characterize the state of IAC with respect to a set of challenges, patterns and anti-patterns identified by a recent Systematic Literature Review study. To address the above goal, we gathered the opinions of researchers and practitioners w.r.t. their experiences in IAC projects. Our dataset includes 47 opinion data points related to a large set of projects conducted in 10 different countries. We aim to contribute to the body of evidence in the area of IAC, for the benefit of researchers and practitioners in conducting future successful IAC projects in SE. As an output, the study presents a set of empirical findings and evidence-based recommendations to increase the success of IAC projects. [less ▲]

Multilingual pedagogies hold promise in our heterogeneous and fast developing world on account of their inclusiveness and support for social justice and political participation. In order to help early years practitioners develop these innovative methods, researchers at the university of Luxembourg offered an inquiry-based professional development course which aimed to develop the practitioners’ understanding of multilingualism, help them design literacy activities in a range of languages, and enable them to evaluate their practices. The participants were teachers and para-professionals who work with 3- to 5-year-olds in nursery schools, crèches and day care centers. These institutions focus on the learning of Luxembourgish, sometimes at the expense of home languages and of French and German, both official languages in Luxembourg. The focus on Luxembourgish must be seen in relation to the heterogeneous intake where approximately 60% of the children do not speak Luxembourgish. This paper presents the preliminary findings of a questionnaire on multilingualism, language learning and literacy practices answered by 50 practitioners prior to and following the above-mentioned professional development course. The data were triangulated with the practitioners’ video-recorded language activities. The findings show that the teachers and para-professionals view multilingualism positively and promote Luxembourgish through language use and frequent literacy activities. They occasionally communicated with the youngsters in their home languages - if known - and did not object to the children using them with peers and adults. While almost all practitioners stated that the children spoke in their home language, they diverged in their beliefs regarding the appropriateness of their use. Answers were more convergent in the post-test. The findings should deepen our understanding of early years practitioners’ beliefs and language practices and help find strategies for developing multilingual pedagogies. [less ▲]
