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 ▲]

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 ▲]

Recent extensions of description logics for dealing with different forms of non-monotonic reasoning don’t take us beyond the case of defeasible subsumption. In this paper we enrich the DL EL⊥ with a (constrained version of) a typicality operator •, the intuition of which is to capture the most typical members of a class, providing us with the DL EL•⊥. We argue that EL•⊥ is the smallest step one can take to increase the expressivity beyond the case of defeasible subsumption for DLs, while still retaining all the rationality properties an appropriate notion of defeasible subsumption is required to satisfy, and investigate what an appropriate notion of non-monotonic entailment for EL•⊥ should look like.

Semantic web technologies such as ontologies can foster the reusability of learning material by introducing common sets of concepts for annotation purposes. However, suggesting learning material from an open, heterogeneous corpus is a nontrivial problem. In this paper, we propose an extensible and lightweight modular ontology for programming education. Its main purpose is to integrate annotated learning material related to programming into an IDE such as Eclipse. Our ontology is based on a modular architecture, which is extensible with respect to different programming languages. Aligning language-specific concepts with user-specific tags allows us to suggest learning resources for code elements in a fine-grained and cross-curricular way. Our concrete implementation establishes relations between learning aspects in Java or C code and annotated resources such as articles on online question-and-answer sites. [less ▲]

The objective of the study is the extension of the existing 2D FEniCS implementation of Cosserat elasticity to the 3D case. The first step is the implementation of a patch-test for a simple problem in classical elasticity as a Timoshenko's beam - this study will show that DOLFIN could offer approximated solutions converging to the analytical solution. The second step is the computation of the stress in a plate with a circular hole. The stress concentration factors around the hole in classical and Cosserat elasticities will be compared, and a convergence study for the Cosserat case will be realised. The third step is the extension to the 3D case with the computation of the stress concentration factor around a spherical cavity in an infinite elastic medium. This computed value will be compare to the analytical solution described by couple-stress theory. [less ▲]

Extensions of the concept of distance to more than two elements have been recently proposed in the literature to measure to which extent the elements of a set are spread out. Such extensions may be particularly useful to define dispersion measures for instance in statistics or data analysis. In this note we provide and discuss an extension of the concept of distance, called n-distance, as functions of n variables. The key feature of this extension is a natural generalization of the triangle inequality. We also provide some examples of n-distances that involve geometric and graph theoretic constructions.

The concept of system signature was introduced by Samaniego for systems whose components have i.i.d. lifetimes. We consider its extension to the continuous dependent case and give an explicit expression for this extension as a difference of weighted means of the structure function values. We then derive a formula for the computation of the coefficients of these weighted means in the special case of independent continuous lifetimes. Finally, we interpret this extended concept of signature through a natural least squares approximation problem. [less ▲]

Extensive growth based on the expansion of inputs is likely to be subject to diminishing returns. Therefore it is often viewed as having no effect on per capita magnitudes in the long run. This Paper argues that periods of extensive growth through capital accumulation may be a precursor to periods of intensive growth during which output per unit of input grows through endogenous technical change. Such a sequence of stages of development occurs as capital accumulation affects the incentives to engage in labour-saving technical change. A steady rise in the capital-labour ratio affects the relative scarcity of factors of production, their (expected) relative price, and induces innovation investments.<P>(This abstract was borrowed from another version of this item.)
