UML models are standard artifacts used by software engineers for designing software. As software is designed, different UML diagram types (e.g., class diagrams and sequence diagrams) are produced by software designers. Since the various UML diagram types describe different aspects of a software system, they are not independent but strongly depend on each other, hence they must be consistent. Inconsistencies cause faults in the final software systems. It is, therefore, paramount that they get detected, analyzed, and fixed. Consistency rules are a useful tool proposed in the literature to detect inconsistencies. They categorize constraints that help in identifying inconsistencies when violated. This case study aims at collecting and analyzing UML models with OCL consistency rules proposed in the literature and at promoting the development of a reference benchmark that can be reused by the (FM-)research community. We collected 33 UML consistency rules and 206 different UML diagrams contained in 34 open-source UML models presented in the literature. We propose an FM-based encoding of the consistency rules in OCL. This encoding allows analyzing whether the consistency rules are satisfied or violated within the 34 UML models. To assess the proposed benchmark, we analyzed how the UML models, consistency rules, diagram types contained in the benchmark help in assessing the consistency of UML models, and the consistency of diagrams across the different software development phases. Our results show that the considered UML models and consistency rules allowed identifying 2731 inconsistencies and that those inconsistencies refer to different software development phases. We concluded that the considered UML models and consistency rules could be considered as an initial benchmark that can be further extended by the research community. [less ▲]

This chapter examines recent language education laws in Luxembourg as well as the ways in which early years practitioners appropriated the new policies and put them into practice. The chapter begins with a brief introduction of the linguistic landscape in Luxembourg and a summary of the dynamic development of the country’s early childhood education system. Special emphasis is put on recent changes in language education policies, which call for a more inclusive and multilingual early language education. Monolingual practices now need to open up to flexible language use and offer children opportunities to capitalize on their entire semiotic repertoire for communicating, meaning-making, and learning. The central concerns of this chapter are the ways in which policy changes influence educational practices in formal and non-formal settings and how professional development shapes this process. In order to address these questions, the authors review literature on language education policy, translanguaging and professional development and examine studies on early language education in Luxembourg. Next, they discuss recent initiatives of professional development in formal and non-formal early years settings as well as their outcomes. Finally, they present critical issues such as the practitioners’ reflexivity and responsibility and the sustainability of professional development. Future research directions include family language policies, partnerships between families and early childhood institutions and children’s languaging practices inside and across these institutions.

Wo und wie ereignen sich Grenzen? Inwiefern werden Migrant*innen zu Teilnehmer*innen von Regulierungspraktiken instrumentalisiert und in welcher Form werden damit auch Fragen der Integration berührt? Unter diesen Aspekten setzen sich die Beiträger*innen dieses italienisch- und deutschsprachigen Bandes mit dem Verhältnis von Flucht, Grenze und Integration in literatur- und kulturwissenschaftlicher sowie räumlich-geographischer Perspektive auseinander. Ziel ist es, die Momente von Flucht, Grenze und Integration in ein produktives Spannungsverhältnis zu bringen und als eine von Phänomenen der Deplatzierung zusammengehaltene Trias zu diskutieren.

Drawing on two longitudinal case-studies, this study aimed to identify some salient characteristics of the agentic behaviour of two young emergent multilinguals in two different multilingual contexts: Luxembourg and Israel. Despite the fact that the studies were conducted independently, the two cases were analysed together owing to the similarities in the research methods such as video-recorded observations, and semi-structured interviews with teachers and parents. The data were analysed through thematic and conversational analyses. Findings showed that a boy who learned Luxembourgish in Luxembourg and a girl who learned Hebrew in Israel, were outgoing and active learners who influenced their learning environment. We identified ten types of agentic behaviour, including engaging in repetition after peers and the teacher, creatively producing language, translanguaging, and self-monitoring. Despite differences of the children's sociocultural and linguistic backgrounds, and the language policies of their educational settings, we found a striking overlap in their language-based agentic behaviours. We suggest that the identified types can encourage further research in this field. Although our study with talkative children allowed us to observe many types of agentic behaviours, we cannot claim that less outgoing children or children who do not show the same behaviours do not have ways of expressing their agency.

In diesem Beitrag wird die Bedeutung von nationalen Grenzen für räumliche Identitäten in Grenzregionen analysiert. Dafür wird ein mehrdimensionales Analysemodell entwickelt und am Beispiel der Großregion SaarLorLux gefragt, wie die Einwohner den Raum repräsentieren und wie sie ihre alltagskulturellen Praktiken räumlich organisieren. Außerdem werden räumliche Projektionen im politischen Diskurs aufgedeckt und rekonstruiert, inwiefern diese in Identifizierungsprozessen wirksam sind. Die Betrachtungen stützen sich auf eine Repräsentativbefragung der Einwohner Luxemburgs und der an das Großherzogtum angrenzenden Gebiete in Frankreich, Belgien und Deutschland. Der Beitrag zeigt, dass nationale Grenzen in den Identifikations- und Identifizierungsvorgängen der Einwohner der Großregion SaarLorLux trotz grenzüberschreitender Verflechtungen und Alltagsgeographien eine wichtige Rolle spielen, aber nicht zwangsläufig als stabile Ordnungskategorien.

We propose a novel methodology for designing oversampled discrete Fourier transform-modulated uniform filter banks. The analysis prototype is designed as a Nyquist filter, whereas the synthesis prototype is designed to guarantee perfect reconstruction (PR) considering oversampling. The resulting optimization problem fits into the disciplined convex programming framework, as long as some convex objective function is employed, as the minimization of either the stop-band energy or the maximum deviation from a desired response. The methodology also accounts for near-PR multiplierless approximations of the prototype analysis and synthesis filters, whose coefficients are obtained in the sum-of-power-of-two (SOPOT) space. The quantized coefficients are computed using successive approximation of vectors, which is able to yield filters with a reduced number of SOPOT coefficients in a computationally efficient manner. The proposed methodology is especially appealing for supporting actual hardware deployments, such as modern digital transparent processors to be used in next-generation satellite payloads. [less ▲]

Today, higher education is typically seen as offering the most assured pathways to secure careers and low unemployment rates. Yet, increasingly some groups, not least higher education graduates and their families paying ever-higher tuition fees, question the taken-for-granted contributions higher education makes to individuals and society as a whole. Despite decades of mass higher education expansion, even societies with strong systems continue to struggle to achieve their goal of universalizing participation and equalizing access. While in part this is due to limited public or corporate funding for (affordable) study opportunities, differentiated systems, such as in the US, also lack policy coordination and effective governance, providing a surfeit of options. While participation rates have climbed worldwide, higher education systems continue to produce winners (“insiders”) and losers (“outsiders”), even as the “schooled society” shifts the occupational structure upward. Market-oriented higher education systems face increasing privatization, which also involves financializing university governance. Many states have retrenched investments that had once underwritten universities’ flourishing and their moves toward massification. Tensions have deepened over who should pay for rising costs, exacerbated in an era of increasing status competition via higher education. In the face of such challenges globally, which alternatives exist? A prominent possibility, pioneered in Germany in the 1970s, are “dual study” programs offered by several organizational forms, from vocational academies to universities of applied sciences. Such hybrid programs fully integrate phases of higher education study and paid work in firms. Another potential advantage of apprenticeship training being offered in conjunction with higher education is that this would boost the reputation of apprenticeships overall. The German experience indicates that the attractiveness of the apprenticeship training system as a whole can be bolstered when it offers a viable pathway also for those individuals with a traditional university entrance certificate. If these students seriously consider and choose advanced work-based higher education, this may well increase the standing of apprenticeship training among students, their families, and employers. Thus, dual study programs provide an innovative model for policymaking and implementation. Especially when considering strategies to improve skill formation overall, to reduce the costs individuals must bear in attaining higher education, and to improve the fit between the expectations of employers and potential employees regarding skill formation, dual study programs excel. The origins and contemporary developments in work-based higher education in Germany offer lessons and inspiration for Anglophone countries, with their strong and differentiated higher education systems, to further bolster study programs coordinated with firms.

This paper develops normative approaches for measuring individual-level income insecurity. Using concepts derived from Expected Utility Theory and Prospect Theory, we build a suite of measures designed to capture various facets of psychologically distressing income risk. We present an application for the US and Germany from 1993-2013, employing conditionally heteroskedastic fixed-effects models to generate predictive densities for future incomes. Our results reveal much higher levels of income risk in the US relative to Germany, which can be mostly attributed to a higher level of autonomous, time-invariant volatility. State-by-state variations in liberal/conservative political administrations partially explain our results, and we find some evidence that trade exposure is a contributing factor in the US. [less ▲]

We here consider the link between individual financial profiles over time and well-being, as measured by life satisfaction. We in particular look at annual self-reported financial worsening and improvement information for over 25,000 individuals in Australian panel data from 2002 to 2017. We first find that satisfaction falls (rises) with a contemporaneous major financial worsening (improvement), with the the largest correlation being with financial worsening. Second, the experience of these financial events in the past continues to be linked to current well-being. Last, only the order of financial-improvement spells relates to well-being: a given number of past years where finances deteriorated has the same association with current well-being whether the deterioration occurred in one continuous spell or was interrupted. We last show that these associations are heterogeneous over the distribution of well-being. [less ▲]
