Since 2008, a reform of vocational training is being implemented in the upper level of secondary education in Luxembourg. The new method consists of: (1) teaching through competencies; (2) modular training where modules can be repeated until they are achieved; and (3) evaluation which has been changed from quantitative to qualitative. The reform continues to face ongoing challenges and resistance from the different actors involved in vocational training. Semi‐structured interviews were carried out with the relevant actors in order to analyse their strategies and perspectives during and after the reform: representatives of the Ministry of Education, teaching staff, school administrations, enterprises, parents, and pupils. A heuristic model of resistance to change in education was constructed, based on these interviews. A general fatigue with the reform has spread; and this is at a moment when the Ministry wants to implement new changes to the aforementioned law. In order to make the reform viable, a new negotiated agreement based on the interests of the different players should be achieved. [less ▲]

The assumption underlying the present study is that solving individually or collaboratively a non-routine problem influences the implementation of the strategies. In our experiment, 909 3rd graders from Luxembourg primary schools were randomly assigned to two different groups: an individual group and a collaborative group. In both groups students had to solve a non-routine problem in which several solving strategies can be admitted. The results showed that among the correct problem solving strategies, the formal strategy and the guess and check strategy were proportionally more implemented in the collaborative condition than in the individual condition. Implications of these results for educational purposes are discussed; suggestions for future research are made. [less ▲]

This paper is concerned with the types of models researchers use to analyze empirical data in the domain of social judgments and decisions. Models for the analysis of judgment data may be divided into two classes depending on the criteria they optimize: Optimizing an internal (mathematical) criterion function with the aim to minimize the discrepancy of values predicted by the model from obtained data or incorporating a substantive underlying theory into the model where model parameters are not only formally defined, but represent specified components of judgments. Results from applying models from both classes to empirical data exhibit considerable differences between the models in construct validity, but not in empirical validity. It may be concluded that any model for the analysis of judgment data implies the selection of a formal theory about judgments. Hence, optimizing a mathematical criterion function does not induce a non-theoretical rationale or neutral tool. As a consequence, models satisfying construct validity seem superior in the domain of judgments and decisions. [less ▲]

Although GNSS techniques are theoretically sensitive to the Earth center of mass, it is often preferable to remove intrinsic origin and scale information from the estimated station positions since they are known to be affected by systematic errors. This is usually done by estimating the parameters of a linearized similarity transformation which relates the quasi-instantaneous frames to a long-term frame such as the International Terrestrial Reference Frame (ITRF). It is well known that non-linear station motions can partially alias into these parameters. We discuss in this paper some procedures that may allow reducing these aliasing effects in the case of the GPS techniques. The options include the use of well-distributed sub-networks for the frame transformation estimation, the use of site loading corrections, a modification of the stochastic model by downweighting heights, or the joint estimation of the low degrees of the deformation field. We confirm that the standard approach consisting of estimating the transformation over the whole network is particularly harmful for the loading signals if the network is not well distributed. Downweighting the height component, using a uniform sub-network, or estimating the deformation field perform similarly in drastically reducing the amplitude of the aliasing effect. The application of these methods to reprocessed GPS terrestrial frames permits an assessment of the level of agreement between GPS and our loading model, which is found to be about 1.5 mm WRMS in height and 0.8 mm WRMS in the horizontal at the annual frequency. Aliased loading signals are not the main source of discrepancies between loading displacement models and GPS position time series. [less ▲]

The aim of this study was to examine the effect of aging on strategy selection in a paired-associate word task. Twenty-eight younger adults (mean age = 20.68 years) and 28 older adults (mean age = 68.46 years) studied 39 pairs of concrete, middle and abstract words. The concreteness level was manipulated in order to modify the benefit of imagery and sentence strategies in relation to task characteristics. The results showed an age difference in strategy selection in relation to concreteness level. Older adults showed less adaptive strategy selection for the imagery strategy but not for the sentence strategy. Change in strategy selection did not seem to be explained by better efficiency of sentence than imagery, so this study suggests a partial reduction of strategy adaptivity during aging. [less ▲]

The models@run.time paradigm promotes the use of models during the execution of cyber-physical systems to represent their context and to reason about their runtime behaviour. However, current modeling techniques do not allow to cope at the same time with the large-scale, distributed, and constantly changing nature of these systems. In this paper, we introduce a distributed models@run.time approach, combining ideas from reactive programming, peer-to-peer distribution, and large-scale models@run.time. We define distributed models as observable streams of chunks that are exchanged between nodes in a peer-to-peer manner. lazy loading strategy allows to transparently access the complete virtual model from every node, although chunks are actually distributed across nodes. Observers and automatic reloading of chunks enable a reactive programming style. We integrated our approach into the Kevoree Modeling Framework and demonstrate that it enables frequently changing, reactive distributed models that can scale to millions of elements and several thousand nodes.
