In this article, we’ll be wondering about the point, the challenges and the limits of integrating competences in Higher Education, starting from three experiences lead in Urban and Economic Geography. For this purpose, we’ve managed to combine works from Higher Education specialists and observations from the field. This reflection has been built in three stages. First, we’ll be reminding the foundations and specificities of the competence based approach. Then, we’ll be analysing our three experiences with the help of a common grid allowing us to successively consider the original needs and motivations, the process design, its trial and its adjustment. Finally, we’ll be trying to draw conclusion in terms of impacts on the students learning process, and impacts on the way teachers approach their teaching process, its limits and constraints.

The aim of this paper was to use a parametric stochastic frontier approach (coming from the economic literature) to explore the impact of the concept of activity (taken in a broad sense: i.e., including both professional and non-professional activities) on the constitution and the care of cognitive reserve among the European population aged 50 and up. For this purpose, we use individual data collected during the first wave of SHARE (Survey on Health, Ageing and Retirement in Europe) performed in 2004. The advantages of this survey were (1) it included a large population (n = 18,623) geographically distributed throughout Europe; and (2) it simultaneously analyzed several dimensions (physical and mental health, mobility, occupational activities, socioeconomic status, etc.). Our results confirm the positive impact of occupational activities on the cognitive functioning of elderly people. These results are discussed in terms of the prevention of cognitive aging and Alzheimer’s disease, and more particularly of retirement policy issues. [less ▲]

In less than ten years, a corporate property market has emerged in Wallonia. This market first covered offices and retail units and recently extended to semi-industrial establishments. Its development is largely related to the creation of a new type of demand resulting from the growth of new service activities and from new expectations regarding physical units, environment, accessibility and location choices – on both sub-regional and local scales. It has been favoured by the appearance of new property stakeholders, Belgians as well as foreigners (developers, investors and estate agents), but also by public authorities (the Walloon Region and economic development supra-communal agencies). This market’s emergence is related to the deepening of territorial contrasts as property development projects usually reinforce strong areas. [less ▲]

Thermal infrared (IR) lenses require efficient anti-reflection coating. Moth-eye (or egg-box) 2D subwavelength gratings have demonstrated their ability to reach a very high transmission for a wide wavelength and angular range. The use in thermal IR is simplified by the lower resolution for lithographic technology, compared to visible waveband. However, deeper structures must be engraved and lithography must be adapted to IR materials. In order to be cost-effective, the patterning must be produced by replication techniques, such as embossing. Our laboratory is now experimenting hot embossing of moth-eye patterns in chalcogenide substrates. In this paper, theoretical analysis, micro-lithographic technology and manufacturing processes are detailed. [less ▲]

This paper deals with the application of statistical process control techniques for damage diagnosis based on vibration measurements. The first approach considered in this work is based the Stochastic Subspace Identification (SSI) algorithm, from which a Kalman model is constructed to fit the measured response histories of the undamaged (reference) structure. This model may be used to make a prediction of the newly measured responses. The residual error between the model predictions and the actual measurements is defined as a damage-sensitive feature. Outlier statistics provides then a quantitative indicator of damage. The advantage of the method is that model extraction has to be performed only once using the reference data and that no further modal identification is needed. Thus on-line structural health monitoring may easily be realized. In the second approach, principal component analysis (PCA) of the sensor time-responses is used to extract principal directions (i.e. features), which define a subspace that is representative of the dynamics of the instrumented structure. Any change in the response of a single sensor affects the subspace spanned by the complete sensor response set. It follows that the subspace corresponding to the current state of the structure can be compared to the subspace of the initial state of the structure, assumed to be healthy, in order to diagnose possible damage. Principal component analysis may also be performed for every potential subset of damaged sensors in order to identify the involved sensor, and, therefore, the damaged substructure. [less ▲]

In this paper I review the operation of the exception clause provided in Article 19 of the Belgian Code of Private International Law (Act of 16 July 2004 entered into force on 1st of October 2004). Much has been written on the need but also on the risks associated with such exception clauses. The introduction of this mechanism has been much criticized in Belgian scholarly works (among others by Barnich). I attempt to downplay or nuance some of the criticisms by showing that when properly applied, the exception clause does not call into question the operation of other conflict of laws rules. In order to do so, I analyze the main requirements of Article 19, in the light of the foreign experiences with similar mechanisms (inter alia the Swiss experience and the experience of the 1980 Rome Convention).

Consider N players, respectively owning x\, xi,..., x^ monetary units, who play a sequence of games, winning from and losing to each other integer amounts according to fixed rules. The sequence stops as soon as (at least) one player is ruined. We are interested in the ruin process of these N players, i.e. in the probability that a given player is ruined first, and also in the expected ruin time. This problem is called theN-player ruin problem. In this paper, the problem is set up as a multivariate absorbing Markov chain with an absorbing state corresponding to the ruin of each player. This is then discussed in the context of phase-type distributions where each phase is represented by a vector of size N and the distribution has as many absorbing points as there are ruin events. We use this modified phase-type distribution to obtain an explicit solution to the N-player problem. We define a partition of the set of transient states into different levels, and on itgive an extension of the folding algorithm (see Ye and Li (1994)). This provides an efficient computational procedure for calculating some of the key measures. [less ▲]

The metal hyperaccumulator Arabidopsis halleri exhibits naturally selected zinc (Zn) and cadmium (Cd) hypertolerance and accumulates extraordinarily high Zn concentrations in its leaves. With these extreme physiological traits, A. halleri phylogenetically belongs to the sister clade of Arabidopsis thaliana. Using a combination of genome-wide cross species microarray analysis and real-time reverse transcription-PCR, a set of candidate genes is identified for Zn hyperaccumulation, Zn and Cd hypertolerance, and the adjustment of micronutrient homeostasis in A. halleri. Eighteen putative metal homeostasis genes are newly identified to be more highly expressed in A. halleri than in A. thaliana, and 11 previously identified candidate genes are confirmed. The encoded proteins include HMA4, known to contribute to root-shoot transport of Zn in A. thaliana. Expression of either AtHMA4 or AhHMA4 confers cellular Zn and Cd tolerance to yeast (Saccharomyces cerevisiae). Among further newly implicated proteins are IRT3 and ZIP10, which have been proposed to contribute to cytoplasmic Zn influx, and FRD3 required for iron partitioning in A. thaliana. In A. halleri, the presence of more than a single genomic copy is a hallmark of several highly expressed candidate genes with possible roles in metal hyperaccumulation and metal hypertolerance. Both A. halleri and A. thaliana exert tight regulatory control over Zn homeostasis at the transcript level. Zn hyperaccumulation in A. halleri involves enhanced partitioning of Zn from roots into shoots. The transcriptional regulation of marker genes suggests that in the steady state, A. halleri roots, but not the shoots, act as physiologically Zn deficient under conditions of moderate Zn supply.

First published in the "Kant-Studien" (1909), Rickert's "two ways of the theory of knowledge" is a master-piece of the debate between neo-Kantianism and Husserl's phenomenology. In this text, Rickert - with Windelband and Lask one of the main representatives of the Heidelberg neo-Kantian school - presents in a clear and synthetic way the principles of his critical philosophy. The French translation of the German Text is here accompanied by a substantive commentary (100 p.) on the Rickert-Husserl relationship. Discussed topics include: antipsychologism and normative logic, theory of obviousness, nature of judgement and truth, heterological relation between subject and object, etc. Those topics are examined from the methodological distinction between "noetical analysis" (or act-analysis) and "noematical analysis" (content-analysis), which can be regarded at some extend as common to Husserl and Rickert.

The facies architecture, sedimentary dynamics and palaeogeographical evolution were reconstructed for a number of Middle to Late Frasnian buildups developed on a carbonate platform on the south side of the Dinant Synclinorium (Belgium, France). Nine facies were documented in the buildups, each characterized by a specific range of textures and assemblage of organisms. Sedimentological evidence suggests that facies (1) and (2) correspond to iron bacteria-sponge-dominated communities, developing in a quiet aphotic and hypoxic environment. (3) developed between the storm wave base and the fairweather wavebase, in a oligophotic environment. (5), with stromatolitic coatings and thrombolitic bushes developed close to the fairweather wave base. (6) and the fenestral limestone. (7) correspond to an environment with slightly restricted water circulation. (8) developed at subtidal depths in a quiet, lagoonal environment. The main differences between the Middle and Late Frasnian mounds concerns facies architecture and are a consequence of different palaeoceanographic setting. The large flattened Middle Frasnian Arche and Lion buildups show limited vertical differentiation, large-scale progradation features, extensive exportation of material towards off-reef environment and development of inner lagoonal facies. They grew offshore from a well-developed carbonate platform with a healthy carbonate factory. Middle Frasnian sea level fluctuations were relatively mild, and sedimentation was able to counterpart sea-level rise. At the opposite, during Late Frasnian, severe eustatic rises, together with rising oceanic hypoxic conditions were responsible for frequent collapses of the carbonate factory, drowning of the Middle Frasnian carbonate platform and development of buildups with relatively limited lateral extension, high vertical facies differentiation, low potential for material exportation and high content in microaerophilic iron bacteria.
