Information and Communication Technologies have impacted every business in the last decades. Education, as part of the knowledge business, has acknowledged the digital revolution and educational policy makers have tried to harness the powers of these new tools and to address the associated challenges, with more or less success. In Luxembourg, we have seen several attempts to help schools to strategically integrate ICT into everyday pedagogical activities. However, teacher beliefs associated with value of using technology (value beliefs) are rather understudied. The aim of this study was to document and understand technology acceptance of teachers to ensure successful technology integration. Quantitative data was collected through a survey of 127 teachers and analyzed through a mixed-method approach. Findings revealed both the dependence of value beliefs on perceived ease of use, subjective norms and a pedagogical approach and their independence from gender, age, experience, and school subject.

This paper investigates whether relative corporate sustainability as measured by the SAM sustainability ranking and sustainability reporting in terms of Global Reporting Initiative (GRI) application levels are associated with a higher market valuation. We conduct a value relevance study for the 600 largest European companies with the Feltham and Ohlson valuation model as a reference point. Our results indicate that for the observation period 2001 to 2011, the association between corporate sustainability and market value is positive. The empirical evidence of a positive relationship between GRI reporting and market value is statistically significant in some but not all of the model specifications. We find no evidence of interaction between the value relevance of corporate sustainability and sustainability reporting, nor do we find any positive effect of external assurance on the capital market perception of GRI application levels. Our results support the notion that conducting business in accordance with ethical norms is also a shareholder valueincreasing business strategy. However, it is not possible to verify the information given in sustainability reports through external assurance. [less ▲]

Increasing customer requirements and high pressure from global competition are forcing companies to a holistic optimization of their business and production processes. To ensure the competiveness of enterprises in future, it is necessary to introduce a process-oriented view instead of a departmental thinking. This paper describes the application of Value Stream Management by the University of Luxembourg in collaboration with the industrial partner Rotarex S.A., a provider of gas control solutions headquartered in Luxembourg. With the help of Value Stream Analysis and Design, relevant material and information flows are captured, analyzed and finally optimized. [less ▲]

The University of Luxembourg has recently launched its learning factory, the “Lean Manufacturing Laboratory”. With the help of this manual assembly line, students gain valuable insights in the operation of a manufacturing line as well as in buffer, waste and congestion management. Currently, one of the main research topics at the University of Luxembourg in the field of Lean Management is the further development of the method Value Stream Management (VSM). The application of VSM in the “Lean Manufacturing Laboratory” with a projected focus on industry and service sectors reveals the need for a standardized VSM approach. Thus, one of the research objectives is the development of a common VSM method accompanied by standardized software and process interfaces to ensure robust product and information flows within a company and also throughout supply chains. On the way towards a VSM method as standard, existing VSM approaches have to be investigated and validated. By a detailed comparison of existing VSM approaches, all necessary fields of action for the development of a standardized Value Stream Management approach are shown. [less ▲]

Das Thema „Wertstrom Management“ wird in Luxemburg bereits in der Bachelor Ausbildung vermittelt und für die Master vertieft. In der Forschung erweist dieses Werkzeug großes Potential zur Synchronisation und Optimierung der Wertschöpfung im Unternehmensverbund, das wir hier vorstellen möchten: Mit der Methode VSM lässt sich Verschwendung erkennen und Wertschöpfungspotentiale heben. Die Verschwendung wird damit nicht nur in den produktiven Unternehmensbereichen, sondern auch in indirekten Bereichen und ebenso in Verwaltungsfunktionen und administrativen Abteilungen visualisiert. Man erkennt Möglichkeiten, die Verschwendung abzubauen und die Wertschöpfung zu erhöhen. Bei der praktischen Anwendung dieses leistungsfähigen Werkzeugs erwiesen sich die Schnittstellen zwischen den Unternehmen als immerwährende Quellen von Verschwendung und Ineffizienzen. Hier sind die unterschiedlichen Ausprägungen der Methode VSM hinderlich für eine durchgängige Anwendung dieser Methode. Aus dieser Erkenntnis heraus schlagen wir eine Vereinheitlichung der „Best Practices“ als Industrie Standard bzw. als internationale Norm vor. Im Rahmen der aktuell laufender Forschungsprojekte an der Universität Luxemburg werden Methoden entwickelt, um das Wertstrom Management international zu standardisieren und allgemein zu vereinheitlichen.

The concept of circular economy (CE) aims to close and slow resource loops without neglecting the goals of sustainable development. Recently, the concept received encouraging attention among researchers and business experts to be a convenient solution to move away from the finite linear economy concept to a more sustainable solution. However, this change of paradigm is only possible if we consider systems in a holistic manner and can localize the preventing hurdles. Value stream mapping (VSM) is a commonly known lean method, used to develop current state visualization of product and information flows within organization, helping to seek weaknesses and improve process flows. The motivation of this paper is a new C-VSM model, which enables its users to evaluate and visualize connected process-chains regarding CE on different levels in a holistic manner. For this purpose, the traditional VSM model was adapted towards the needs and requirements of CE through the application of a new representation method, additional indicators, and an appropriated evaluation system. C-VSM is in line with the current political and industrial objectives to apply CE principles by enabling a holistic reflection and consideration of supply-chains (SCs) on different levels. The model itself is validated through an extensive cross-company case study. [less ▲]

Luxembourg is a multicultural and multilingual country with three official national languages and approximately half of the population (47.1%) composed of foreigners (Statec, 2022). Although most foreigners in Luxembourg have European roots, the number of non-Europeans is rising, with sizeable American and Japanese communities. The US, as target country for immigration is known for its diversity. Japan is one of the most ethnically homogeneous countries in the world. The purpose of this study is to explore the acculturation experiences of Americans and Japanese in Luxembourg. We explore, if and to what extent this contrast between multicultural US and monocultural Japan adds to the complexity of adapting to a multicultural and multilingual context. We focus on the intergenerational value transmission (i.e., language, traditions) within this context. Adopting a qualitative approach, we explored in semi-structured interviews, supplemented by visual primes, different facets of daily life including language practices. Participants were 8 women (5 American, 3 Japanese, age range between 35 and 61 years, M = 48.3) in international marriages with children (on average 2) and most having lived in Luxembourg for more than 10 years. Results show the various compromises participants made regarding language (i.e., within-family language choice, school language choice, friendship groups) and traditions (i.e. local and home traditions). Although the benefits of a multilingual society were noted among all participants, challenges were also experienced. The results shed light on the difficulty of integration and transmission of values in a multicultural context. Implications and differences between Japanese and American participants will be discussed. [less ▲]

Value-added (VA) modelling aims to quantify the effect of pedagogical actions on students’ achievement, independent of students’ backgrounds (e.g., [1]); in other words, VA strives to model the added value of teaching. VA is typically used for teacher and/or school accountability (e.g., [2]). Although, VA models have gained popularity in recent years—a substantial increase of publications is to be observed over the last decade—, there is no consensus on how to calculate VA, nor is there a consensus whether and which covariates should be included in the statistical models (e.g., [3]). The aim of the present study is to conduct a to date non-existent integrative review on VA modelling in primary and secondary education. Starting with an exhaustive literature research in the ERIC, Scopus, PsycINFO, and Psyndex databases, we reviewed and thoroughly classified 674 VA publications from 32 different countries. Half of the studies investigated VA models at teacher level; the remaining looked at school or principal level. 370 studies used empirical data to calculate VA models. Most of these studies explained their covariates, but approximately 15% did not specify the model. Most studies used prior achievement as a covariate, but cognitive and/or motivational student data were almost never taken into consideration. Moreover, most of the studies did not adjust for methodological issues such as missing data or measurement error. To conclude, given the high relevance of VA—it is primarily used for high-stakes decisions— more transparency, rigor and consensus are needed, especially concerning methodological details.

Value-added (VA) models are used for accountability purposes and quantify the value a teacher or a school adds to their students’ achievement. If VA scores lack stability over time and vary across outcome domains (e.g., mathematics and language learning), their use for high-stakes decision making is in question and could have detrimental real-life implications: teachers could lose their jobs, or a school might receive less funding. However, school-level stability over time and variation across domains have rarely been studied together. In the present study, we examined the stability of VA scores over time for mathematics and lan- guage learning, drawing on representative, large-scale, and longitudinal data from two cohorts of standardized achievement tests in Luxembourg (N = 7,016 students in 151 schools). We found that only 34–38% of the schools showed stable VA scores over time with moderate rank correlations of VA scores from 2017 to 2019 of r = .34 for mathematics and r = .37 for language learning. Although they showed insufficient stability over time for high-stakes decision making, school VA scores could be employed to identify teaching or school practices that are genuinely effective—especially in heterogeneous student populations.

Autonomous agents are supposed to be able to finish tasks or achieve goals that are assigned by their users through performing a sequence of actions. Since there might exist multiple plans that an agent can follow and each plan might promote or demote different values along each action, the agent should be able to resolve the conflicts between them and evaluate which plan he should follow. In this paper, we develop a logic-based framework that combines modal logic and argumentation for value-based practical reasoning with plans. Modal logic is used as a technique to represent and verify whether a plan with its local properties of value promotion or demotion can be followed to achieve an agent's goal. We then propose an argumentation-based approach that allows an agent to reason about his plans in the form of supporting or objecting to a plan using the verification results. [less ▲]
