In this paper we develop an extended Solow growth model with skilled labor emigration which aggregates different labor types from strict complementarity to perfect substitution. Except in two particular cases, balanced growth paths can only be attained asymptotically. We therefore derive an analytical characterization of the transitional dynamics of the model. We are thus able to study the impact of labor elasticity of substitution on the time pattern of per capita income in the country that experiences brain drain. Simulations show that the shape of per capita trajectory depends crucially on the degree of complementarity (substitutability) between labor skills. Given that no income trajectory dominates the others, there is room for policy issues by influencing the elasticity of substitution (Klump and Preissler, 2000). [less ▲]

The paper introduces a methodology for numerical simulation of landslides experiencing considerable deformations and topological changes. Within an interface capturing approach, all interfaces are implicitly described by specifically defined level-set functions allowing arbitrarily evolving complex topologies. The transient interface evolution is obtained by solving the level-set equation driven by the physical velocity field for all three level-set functions in a block Jacobi approach. The three boundary-coupled fluid-like continua involved are modeled as incompressible, governed by a generalized non-Newtonian material law taking into account capillary pressure at moving fluid-fluid interfaces. The weighted residual formulation of the level-set equations and the fluid equations is discretized with finite elements in space and time using velocity and pressure as unknown variables. Non-smooth solution characteristics are represented by enriched approximations to fluid velocity (weak discontinuity) and fluid pressure (strong discontinuity). Special attention is given to the construction of enriched approximations for elements containing evolving triple junctions. Numerical examples of three-fluid tank sloshing and air-water-liquefied soil landslides demonstrate the potential and applicability of the method in geotechnical investigations. © 2012 John Wiley & Sons, Ltd.

Wavelength Division Multiplexed based Passive Optical Networks (WDM-PON) are subjected to wide variety of incidental failures. It is preferred in WDM-PONs to provide fault management (survivability) at link layer level. In this paper, our objective is to determine the factors, which can increase the scope of survivability at link layer, not available currently. We propose a cost-effective recovery mechanism, called ldquoExtended Survivable Passive Access Networkrdquo (e-SPAN). e SPAN is a multi-level protection scheme that has potential to corrects eventual errors that are caused by the transmission system by using different forward error correcting codes at receiver end, thus allowing us to have better performance budget in terms of BER and extended transmission distance of 8 to 12 Km.

The corona virus (COVID-19) pandemic has changed the working lives of people all over the world, amongst others, the labor market has seen a sharp increase in telecommuting. Therefore, the extent of telecommuting in Luxembourg as well as definitions and different arrangements of telecommuting will be presented. Thereafter the chapter looks at merits and demerits of telecommuting and the boundary conditions of successfully working from home by focusing on the extraordinary situation under which telework currently takes place. In this regard, the effects of telecommuting on the individual, the organization and the society are outlined and discussed. Finally, the chapter closes highlighting requirements for effective telecommuting and describing ongoing research about the effects of telecommuting on different working conditions in Luxembourg.

We consider the problem of extending maps from algebras to their profinite completions in finitely generated quasivarieties. Our developments are based on the construction of the profinite completion of an algebra as its natural extension. We provide an extension which is a multi-map and we study its continuity properties, and the conditions under which it is a map. [less ▲]

Recent advancements in the assessment of Complex Problem Solving (CPS) build on the use of homogenous tasks that enable the reliable estimation of CPS skills. The range of problems featured in established instruments such as MicroDYN is consequently limited to a specific subset of homogeneous complex problems. This restriction is problematic when looking at domain-specific examples of complex problems, which feature characteristics absent from current assessment instruments (e.g., threshold states). We propose to utilize the formal framework of Finite State Automata (FSA) to extend the range of problems included in CPS assessment. An approach based on FSA, called MicroFIN, is presented, translated into specific tasks, and empirically investigated. We conducted an empirical study (N = 576), (1) inspecting the psychometric features of MicroFIN, (2) relating it to MicroDYN, and (3) investigating the relations to a measure of reasoning (i.e., CogAT). MicroFIN (1) exhibited adequate measurement characteristics and multitrait- multimethod models indicated (2) the convergence of latent dimensions measured with MicroDYN. Relations to reasoning (3) were moderate and comparable to the ones previously found for MicroDYN. Empirical results and corresponding explanations are discussed. More importantly, MicroFIN highlights the feasibility of expanding CPS assessment to a larger spectrum of complex problems. [less ▲]

Industrial demand response uses a multitude of energy flexibility measures. Their planning and control requires various production IT systems. A widely accepted approach to classify these inhouse IT systems are the levels of the automation pyramid in companies. This paper broadens the scope of this concept to overcome the limitation to companies’ (virtual) borders by including required IT systems that refine and monetarize a company’s energy flexibility, e.g. energy markets, aggregators, etc. Therefore, a holistic approach for the classification of functionalities for industrial demand response across companies and energy markets is developed and applied exemplarily.

Drawing upon the case of a polycentric cross-border metropolitan region in western Europe, this paper seeks to explore population mobility and housing market developments at the regional/international scale. Transnational linkages within this cross-border region intensified with the opening of the borders and the economic development of the Grand Duchy of Luxembourg as a global financial centre and a centre for European Institutions. Today about 44 per cent of employees working in Luxembourg live nearby across the Belgian, French or German border. One of the reasons is that housing prices in Luxembourg are nearly twice those in the neighbouring border regions. This increased mobility has an impact on the residents living in these areas. The research that guides this paper aims to detect perceptions of this phenomenon. Therefore principles of municipal policy, urban planning documents and the local media of three medium sized towns in the borderland are reviewed. Following a rather open research concept based on qualitative approaches (discourse analysis, grounded theory), findings reveal that locational advantages such as the proximity to Luxembourg do play a role; the perception that affordable housing is becoming increasingly critical leads to resentments that mix up with national stereotypes; while city officials report displacement due to the border-effect, they also illustrate the opportunities for regional development; at the same time property developers foster the internationalisation of urban planning. Pointing to the relational geographies that link these different places, the paper discusses the pros and cons of an umbrella concept that might be called ‘cross-border gentrification’. [less ▲]
