Paedomorphosis consists in the retention of larval characters in adult individuals. It has been observed in several species of newts and salamanders. Optimality models were proposed to explain why it occurs in a large range of aquatic habitats. These models predict that paedomorphs can be advantaged in two situations as contrasted as favourable habitats (paedomorph advantage) or harsh habitats where the newts can benefit of delaying metamorphosis provided that competition with metamorphosed individuals is relaxed (best-of-a-bad-lot hypothesis). This last tactic implies that the habitats are stable enough to ensure the survival of individuals that can not leave the pond. In this respect, our aim was to describe behaviour of paedomorphic Alpine newts (Triturus alpestris) dealing with lake drying. We studied a population from an Alpine lake that splits into two parts during summer, one of them drying then totally. We analyzed age structures by means of skeletochronology and capture-marking-recapture. Paedomorphs and metamorphs showed similar age structures with sexual maturity occurring at 4-5 years, suggesting that most paedomorphs did not metamorphose. CMR data revealed that a great proportion of the paedomorphs marked in the drying part of the lake did not metamorphose and survived to drying. We also carried out laboratory experiments using two-compartiments aquaria to simulate lake drying. These experiments proved that paedomorphic newts could cross terrestrial habitats to reach a pond. Thus paedomorphic newts can migrate on land while keeping their larval attributes rather than metamorphosing when their pond is drying up. Such a tactic appears adaptive because polymorphism in such a deep lake reduces competition between individuals (pers. obs.). [less ▲]

The building is not a unique object any more, but results from the assembly of components, among which the envelope is one of the objects assembled. The components are more and more specialised and acquire an actual independence. On the other hand, the components of the building and of the envelope have a large diversity of life cycles; moreover the life duration of the components shortens, because they rapidly become obsolescent from many points of view: technology, technique, performance, functionality, etc., so that their easy transformability, adaptability (and/or removability) becomes an important quality required to them. The conception of new building envelopes must take these aspects into account, in order to obtain a best practice design. [less ▲]

This paper proposes a convenient testing procedure designed for detecting, from preliminary (pooled) OLS estimation of the model, the possible simultaneous presence of indivi-dual effects and heteroscedasticity in the error of a linear panel data regression model. The proposed testing procedure consists in (1) a distribution-free and allowing for unbalanced panel joint pseudo-LM test of the null of no individual effect and no heteroscedasticity and (2) a BMCP based on distribution-free and again allowing for unbalanced panel robust one-directional pseudo-LM tests for identifying the source(s) of departure from the joint null when it is rejected. An empirical example illustrates the usefulness of the testing procedure. [less ▲]

Gender, Work and Positive Actions: Evolution of the Representations of Equal Opportunities on the Belgian Labour Market

Framework of the paper This paper focuses on the representation of equal opportunities in companies and non-profit organisations identified as having best practices in their human resources policies. Our reflections are based on a inter-universities research made during 1998. Our primary focus is to study up to what point the actions posed last years under the topic of equality between men and women on the workplaces contributed to modify the representations and the practices of companies and non-profit organisations (such as hospitals, for example). Research process and questions To reach that goal, we broke up the research process into two parts: first : the evaluative processes aimed at encircling what in our cultural context could be compared to 'best practices' in an equal opportunity sense; second : to test up to what point this concept of equality of chances gets a coverage in the companies and to perceive if the mentality have evolved. The aim here is to see whether the actions set up by the Ministry of Labour and Employment under the topic "positive actions" could have modified the representations around this theme. Is there for example a shift towards the concept of management of diversity like in North America? In short, we tried to see whether, beyond concrete actions which have been undertaken, the values of companies themselves are changing and have evolved. Methods The methodology we used proceeds from a two-levels process : • the qualitative level : we made six case-studies in Belgian companies and non-profit organisations. In each case study, we interviewed employers as much as employees. To reach a certain representativity of the companies, we chose some selection criteria: multinational company versus local company, big company versus SME, secondary, tertiary or non-profit sector, predominantly masculine or feminine jobs, low or high qualifications requirements, etc. • the quantitative level : we made a large investigation by questionnaires on the national scale. We sent those questionnaires to the persons in charge of the Human Resources from 700 companies, and we carried out a statistical processing of the answers. In addition, we have broaden the perspective by identifying similar initiatives at the level of the European Community, and by exchanging theoretical and bibliographical informations through a transnational network. Results The research results reveal that, beyond the concrete actions undertaken, the representations of men and women on the labour market remain strongly linked to the perception of social roles, especially family ones. It seems that there is an agreement around the principle of equal opportunities, but which calls more upon values of equity and justice than of valorisation of women on the labour market or questioning the operating modes of companies. We used in particular Hofstede's concepts of autostereotypes and heterostereotypes within the framework of our analysis. The results of this analysis appear particularly interesting on what is identified as specific competencies, the advantages and the brakes of men and women at the professional level. They also question the opportunity of positive actions and the image these actions have for both men and women. [less ▲]

The dual analysis concept, which is one of the oldest methods of measuring the discretization error of finite element models, suffered by its lack of generality in its original version. In fact, severe restrictions were imposed to the boundary conditions, excluding any mixed problem. These restrictions, related to an analysis where stiffness plays a central role, can be avoided by using the proper reference energy, which is the total complementary energy. This leads to convergence curves which are always on the same side of the exact value and whose distance measures the quality of the analyses. [less ▲]

En 1990 et en 1998, nous avons eu l’occasion de distribuer un questionnaire à plus de 800 étudiants de sept écoles secondaires de la région de Québec dans le but, entre autres, de déterminer certaines composantes de leurs sentiments d’appartenance. La comparaison de données, à une dizaine d’années d’intervalle, s’avère instructive, d’autant plus que nos résultats sont analysés à l’aide d’une méthode multidimensionnelle, la classification ascendante hiérarchique, qui nous permet de décomposer les images globales en une série de profils de réponses et de regrouper les individus interrogés en fonction des similitudes de ce profil. La pluralité des conceptions propres à chaque individu peut ainsi être mise en évidence dans nos échantillons, ce qui nous empêche de considérer la perception des différentes identités nationales comme une réalité homogène. On retiendra, entre autres, qu’en dix ans d’intervalle, la fierté d’être Québécois comme celle d’être Canadien a diminué de 20 % en comparant les échantillons globalement. Toutefois, l’enquête de 1998 nous montre également qu’au delà des options constitutionnelles préférées (63 % de l’échantillon privilégient d’abord l’indépendance ou la souveraineté-partenariat), le fait de considérer simultanément les indicateurs de fierté, de l’image des groupes linguistiques et de la hiérarchie des priorités offre un portrait beaucoup plus nuancé des positions des élèves de secondaire 4 et 5. À sa façon, les contradictions d’une société distincte s’y retrouvent toujours illustrées. [less ▲]
