A reduction of the carbonate-carbon to organic-carbon export rain ratio during glacial times has been for years one of the favourite hypotheses to explain the glacial-interglacial atmospheric CO2 variations. This hypothesis have been tested and implications for the dynamics of sedimentary carbonate preservation and dissolution explored with MBM, a multi-box model of the ocean carbon cycle, fully coupled to the transient early diagenesis model MEDUSA. With this coupled model, a peak reduction of the rain ratio by 40% at the Last Glacial Maximum (LGM) was found to produce a net atmospheric pCO2 reduction of about 40 ppm. Changing shelf carbonate accumulation rates and continental weathering inputs produced a 55-60 ppm reduction. The combination of the two mechanisms generates a 90-95 ppm pCO2 change, which compares well with the observations. However, the resulting model sedimentary record is at odds with actual sedimentary records. Changing carbonate accumulation rates on the continental shelf and variable weathering fluxes depress the calcite saturation horizon (CSH) by about 1 km at the LGM; rain ratio variations depress it by another km. In addition to this large amplitude for the CSH, the changing rain ratio also leads to transition zone changes in the model sedimentary record that are opposite in phase with data-based reconstructions.

From many aspects, one can observe that, by contrast with other times and places, feral pigeons do not have a definite status in contemporary European cities. They seem to be perpetually crossing boundaries between different categories that people usually refer to in order to understand and engage with the world surrounding them. As a part of wildlife in an urban environment, feral pigeons elicit contrasted feelings amongst inhabitants of cities and question cultural distinctions such as domestic/wild, public/private, clean/dirt, etc. This research was a part of a multidisciplinary project aiming at evaluating both ecological and anthropological dimensions of the presence of feral pigeons in Paris. It will be argued that feral pigeons in cities could be viewed as a kind of symbolic disorder. Political measures, scientific interest and citizen behaviors towards them could therefore be understood as attempts to give the pigeons a definite status. This perspective could help improving the management of urban biodiversity by providing clues to integrate its ecological and cultural dimensions. [less ▲]

Notre communication présente les résultats d’une recherche consacrée à la problématique de la reprise d’entreprise familiale par les filles d’entrepreneur. L’analyse de onze études de cas nous a permis d’analyser le processus de succession tel que vécu et perçu par les filles d’entrepreneur qui reprennent l’entreprise familiale, en identifiant les acteurs clés de l’environnement interne et externe. Nous effectuons une lecture des trajectoires en termes de genre, en examinant les phénomènes de séparation et de hiérarchisation. Nous portons une attention particulière à la configuration familiale (composition de la fratrie mixte ou féminine) et au secteur d’activité (à prédominance masculine ou féminine). Nos résultats mettent en évidence des effets de genre importants, notamment en ce qui concerne le choix du cédant en matière de successeur, ce qui amène des conséquences en termes de positionnement et de motivations des filles d’entrepreneur (reprise par choix ou par nécessité). Par ailleurs, le positionnement des filles en tant que successeurs « par défaut » nous permet de souligner des phénomènes de hiérarchisation. Enfin, nos résultats montrent de quelle manière les filles d’entrepreneur, une fois identifiées comme successeurs, se font accepter et construisent leur crédibilité et leur légitimité vis-à-vis de la famille et des parties prenantes.

Parallel to the dramatic growth of its sales and public awareness, the Fair Trade movement has seen its organisational landscape become increasingly diversified. While Fair Trade nonprofit pioneers were initially relatively homogeneous in terms of goals and structures, the economic development of the initiative, driven by the sales of Fair Trade products in mainstream distribution channels, has led to the emergence of a multitude of new actors with much more heterogeneous behaviours – in spite of the general trend towards a stronger market orientation – (Gendron, 2004; Moore, 2004; Nicholls & Opal, 2005; Renard, 2003). When observing the evolution of Fair Trade organisations (FTOs), i.e., organisations claiming to be totally dedicated to Fair Trade, three trends can be observed: Fair Trade pioneers have adopted more business-oriented profiles and more complex and specialised organisational structures; New small Fair Trade businesses have emerged with a stronger economic specialisation on a particular product or distribution channel ; « Old » and « new » FTOs increasingly gather into networks with two types of purposes: to promote Fair Trade and to have a minimum political representation (advocacy networks) and to face common socio-economic challenges (socio-economic networks). The goal of this contribution is to analyse these three trends with the help of a sample of nearly fourty FTOs in Belgium and in the French Rhône-Alpes region. We can thus illustrate the three trends on the basis of both general observations and precise examples. We also try to compare the two regions and to explore to what extent the evolution of FTOs reveals more global trends within the Fair Trade movement. [less ▲]

Le recours au principe de précaution (Ewald 1996) en tant que mode de gestion publique des choix technologiques (Roany 2004), s’inscrit dans un contexte décisionnel en évolution, marqué par une incertitude multidimensionnelle quant aux conséquences environnementales, économiques, sociales, politiques ou encore éthiques des innovations technologiques (Kooiman 1993 ; Callon, Lascoumes, Barthe 2001, Grossman 2006). L’utilisation de ce principe fonde une demande croissante d’ouverture du processus décisionnel qui se traduit par une offre participative accrue, offre en laquelle certains voient la promesse ou le moyen de concrétiser la société de « gouvernance » (Barber 1984 ; Fishkin 1995 ; Beierle, Cayford 2002 ; Willis, Dekay, Morgan, Florig, Fischbeck 2004 ; Sjöberg 2004 ; Larceneux 2005 ; Tabara 2005, Faget 2006). Il ne s’agirait plus seulement de combler l’ignorance des citoyens quant à une question particulière, mais d’articuler l’expertise à la concertation sociale pour construire un référentiel global de sécurité partagé sur base d’une co-orientation des participants au dialogue. On assiste bien, sous le mot d’ordre de précaution, à deux changements concomitants, le premier affectant les critères d’acceptabilité sociale des choix technologiques, le second transformant les processus de construction et de mise en œuvre de la décision ¬ lesquels deviennent, en soi, une source de légitimation sociale (Groux 2005 ; Pidgeon, Poortinga, Rowe, Jones, Walls, O’Riordan 2005). De nouveaux processus délibératifs sont ainsi mis à l’agenda politique et scientifique, créant des enjeux inédits et, jusqu’à présent, peu étudiés. Dans cette nouvelle configuration, la construction de l’acceptabilité sociale des choix technologiques passe par l’organisation d’un dialogue entre politiques, scientifiques, partenaires socio-économiques (stakeholders) et grand public. Ce dialogue porte notamment sur l’application du principe de précaution, non pas comme référentiel d’action substantif, définissant le contenu de la décision, mais comme ensemble de règles procédurales structurant le processus décisionnel de manière telle qu’il puisse être qualifié de « précautionneux » par l’ensemble des acteurs concernés. Une argumentation scientifique n’étant plus suffisante, dans un tel cadre, pour justifier une décision politique, un nouveau cadre décisionnel doit être proposé : le choix se porte actuellement sur des procédures participatives dans laquelle les acteurs concernés, dont les citoyens, co-créeraient un référentiel commun de sécurité. L’élaboration des politiques publiques requiert dès lors une ouverture des champs d’expertise au de nouveaux acteurs. L’exercice de l’autorité revient à animer un enchevêtrement d’interdépendances dont la richesse tient précisément à la capacité à opérer en commun, individuellement et en groupe dans des univers faiblement structurés, des situations à forte turbulence. La tâche n’est pas aisée car elle revient à admettre, au moins à titre provisoire, la relativité et l’absence de hiérarchie des savoirs, le droit de toutes les parties prenantes à prendre la parole, à débattre, y compris de données et d’analyses scientifiques pour participer à une redéfinition collective de la problématique (Gilbert C., 2002). Dans une telle stratégie de communication, l’art impose de s’adresser de façon adéquate aux différents groupes concernés, sans écarter aucun d’entre eux. Il s’agit de créer de nouveaux espaces d’expertise, ouverts à des stakeholders diversifiés, des forums capables de rendre citoyens et gestionnaires conscients de la nécessité d’une ouverture multidimensionnelle. Or les structures traditionnelles permettent rarement de telles intrusions. Le nouvel enjeu des administrateurs est de proposer des options à la fois techniquement efficaces et socialement acceptables. La nouvelle réticulation des structures administratives ne peut résulter d’un simple changement cosmétique mais demande une réflexion stratégique et organisationnelle d’ampleur (Groux J., 2006). C’est le prix à payer pour améliorer les performances instrumentales et axiologiques, c’est-à-dire, augmenter l’efficacité de la planification tout en améliorant son inscription dans la société. Les responsables publics ne manqueront pas de dénoncer le surcoût d’une telle approche et la distribution des moyens de la puissance publique. Sur base d’une approche pragmatique et contextualisée de deux récents conflits environnementaux en Belgique (installation d’antennes GSM et décontamination des sols pollués), les auteurs proposent de développer une analyse de l’action publique en terme de projet, présentant comment à chaque étape de celui-ci, depuis les études exploratoires jusqu’à la conception du projet, sa mise en œuvre et son exploitation, des acteurs différents sont mobilisables, autour d’objectifs différents. Ensembles ils contribuent à créer un univers sécurisant et coopératif, où les incertitudes et insécurités ne sont pas résolues mais au moins construites voire régulées. Quels sont les critères qui permettent de mettre en évidence un processus de modernisation réflexive ? (Beck et al, 2003) Le processus doit s’inscrire dans une logique temporelle, accepter la fluidité des frontières et des identités co-construites et reconnaître la pluralité des rationalités et les limites d’incertitudes. Le dispositif mis en place doit favoriser l’émergence d’une dynamique d’apprentissage. Les deux cas de figure analysés s’inscrivent dans des référentiels politiques différents et leur confrontation permet de mettre en évidence des propriétés spécifiques en matière de processus d’identification des acteurs légitimes, de négociation des règles d’ouverture, d’organisation et de structuration des lieux de rencontre sociale et de construction de centres de référence. Les auteurs proposent d’inscrire l’analyse de l’expertise et des experts qui lui donnent vie dans une perspective sociale concrète en rendant justice à la dynamique temporelle trop souvent négligée.

Comme ses contemporains Wundt ou Dilthey, Franz Brentano s’efforce de déterminer le statut épistémologie de la psychologie scientifique naissante.

Mechatronics deals with the integrated design of a mechanical system and its control system. Moreover, a large number of mechatronic systems may have their natural frequencies and mode shapes dependent on their spatial configuration, which inevitably affects the performance and the stability of the control system. In particular, mechatronic systems, such as machine tools and pick-and-place robots, can be classified as systems with configuration-dependent dynamics, since the relative motion between their flexible components can lead to time-varying boundary conditions. A parametric model able to capture this behavior is proposed using finite element based flexible multibody method. A global modal parameterization is applied for model-order reduction. A linear parameter varying model is derived from these reduced models and can be used in a control design scheme. This methodology is applied to a pick-and-place assembly robot with a gripper carried by a flexible beam (Fig. 1a). Vibrations, which depend on the beam length, decrease the throughput of the machine (Fig. 1b). Linear time invariant and linear parameter varying control strategies are evaluated using the derived linear parameter varying model. [less ▲]

We consider the following decidability problem: Given a linear numeration system U and a set X ⊆ N such that rep_U(X) is recognized by a (deterministic) finite automaton. Is it decidable whether or not X is ultimately periodic, i.e., whether or not X is a finite union of arithmetic progressions? In this work, we give a decision procedure for this problem whenever U is a linear numeration system such that N is U -recognizable and satisfying a relation of the form U_{i+k} = a_1 U_{i+k−1} + · · · + a_k U_i with a_k = ±1 (the main reason for this assumption is that 1 and −1 are the only two integers invertible modulo n for all n ≥ 2).

We consider a three dimensional (3D) finite element modeling of high temperature superconductors (HTS) submitted to a uniform magnetic field varying linearly with time. HTS are characterized by a non linear conductivity described by a power law with the critical exponent, n. We implement an A- phi weak formulation into the opensource solver GetDP. Backward Euler method is used for the temporal resolution and is coupled to a non linear Picard iteration scheme for dealing with the non linear resistivity of HTS.We consider single- and multiple-time step methods and show that the single time step method produces an accurate result in a drastically reduced calculation time for HTS with large pinning strength (or similarly, with large values of n). The finite element formulation is validated by comparing the magnetization of a HTS tube calculated either with our finite element formulation or with other well-known techniques. The numerical method is then applied for comparing the magnetization of cylinders that are drilled by different periodic arrangements of columnar holes parallel to the cylinder axis. [less ▲]

In recent years, the promotion of R&D partnerships between universities, research labs and companies has become a key feature of innovation and development public policies. However, these collaborations turn out to be fragile and their management very complex. In our literature review, the congruence between the nature of innovations (i.e. their radicalness) and the cooperation practices appears as a potentially powerful explanatory factor of interfirm innovation project’s outcome. Following this hypothesis, we explore, on two case studies of projects subsidized by the Walloon Competitive Clusters program, the way actors innovate and organize their actions. Though they face similar constraints, these projects illustrate diverse configurations, not only as to the nature of innovations but also as to cooperation practices. Besides, the analysis reveals that the criteria used to characterize the nature of innovations do not necessarily form a homogeneous set of factors. Considering these observations, we try to identify the main challenges faced by both projects’ partners. [less ▲]

Within the issue of the modernization of public administration, our initial focus is to question the existence of links between a reform within an administration and its organizational identities. Such changes doubtless entail a transform of many aspects of public administration, such as organisational methods, HRM policy, the approach to planning and fulfilling its tasks, structures, terms of reference etc. This transformation involves the upgrading of operational methods and different skills and values, and results in the disruption of the organisational identity and the professional identities of members of the organisation (Fu et al., 1999; Abrams & Hogg, 1987). From empirical data collected within a Belgian Ministry, we assume that the introduction of a New Public Management reform leads to a hybridization of identity logics within public administration, but in other respects, the reform process can eventually be influenced by the identity logics. Using a longitudinal qualitative analysis, we distinguish 7 identity profiles, characterised by their reference to an identity logic (public service, public managerialism or pragmatism) and their perception of the context (congruence or dissonance). Through our case study, our hypothesis of organizational identities and reform process co-structuring appears to be valid, as shown by the hybridization of identity logics within the Ministry. Our results allow us to assume a modification of identity points of reference following a reform, as well as a reinterpretation of this reform through the identity filter. Our longitudinal approach reveals the identity dynamics, by identifying notably the shift processes from one position to another, and leads us to propose a model of contextualized identity dynamics. We are also able to show which factors produce (or are likely to produce) identity shifts, and the frame of mind of each identity profile towards change (1) as it is experienced and (2) in a projective way. These results draw attention to a number of points which provide the basis of further work on their possible application in management. The factors influencing the shift from one identity profile to another are closely linked with the concept of motivation; many studies have demonstrated the linked between different forms of identification and the attitudes or behaviour of the members of an organisation. Several studies have in fact shown the effects of compatible identity (or identification), on the construction of organisational involvement showing how identification impacts on significant attitudes and behaviours in members of an organisation, such as turnover, satisfaction, involvement, cooperation, acceptance of change or internalisation (Foreman & Whetten, 2002; Ashforth & Mael, 1989; Dutton et al., 1994; Reger et al.,1994). Moreover, the diversity of identity profiles and the ways in which they change suggest that differentiated managerial approaches are required, following the idea that there is no single way of reducing dissonance and that the ways of tackling identity issues in a context of change vary from one profile to another. Finally, the interpretative approach proposed by our analytic model could serve as the basis for developing management tools for framing and accompany change processes within an organisation.

Today many people argue that the youth is uninterested in politics; according to them, there is amongst the young people some sort of political apathy. In fact, electoral turnout declines dramatically in all Western democracies, especially among the young voters. However, drawing from a survey on 1437 students (16-18 y. old), we demonstrate that some young people do engage, participate and are interested in politics. Above all, a multifaceted analysis of political participation and interest is needed to depict the political attitudes of the today’s youth. [less ▲]

Le vocable de la « Société du Risque » permet de désigner la transformation systémique des sociétés occidentales post-industrielles où l’individualisation radicale des comportements et des choix accompagne une transformation majeure sur le plan démographique et socio-économique . Dans les pays industrialisés, la différentiation accrue des modèles sociaux, des styles de vie et des modes de participation provoque une crise des modalités de socialisation via les instances de régulation sociale et engendre de nouvelles demandes sociales. Les citoyens ont accès à de plus en plus d’informations et exigent des gouvernants d’être plus écoutés, voire à participer directement au processus de formation de la décision politique, mettant à mal les structures traditionnelles de représentation. Les nouveaux médias et Internet jouent ici aussi un rôle majeur, puisqu’ils permettent de construire rapidement et à peu de frais des réseaux locaux ou alternatifs voire globaux, bien différents des canaux institutionnels. Ces nouveaux réseaux peuvent contribuer à former de nouvelles bases de mobilisation collective fluides et ponctuelles. Face à ces transformations sociales, le système politico-administratif peine à s’adapter et à assurer la légitimation de ses actions. Les pouvoirs publics sont appelés à définir de nouveaux cadres de gestion de l’espace public, plus réflexifs, capables d’aligner les acteurs non seulement sur l’action entreprise proprement dite mais également sur les instruments publics mobilisés, tout en s’inscrivant dans les lignes de force de la globalisation. Les questions propres à la « Société du Risque » contribuent à remodeler et élargir l’espace spatio-temporel pour la gestion des conséquences des risques modernes. Une partie croissante des décisions de régulations politiques, par exemple dans le domaine de la définition des normes d’environnement, est prise à un niveau supranational, le plus souvent européen, espace politique original qui tend à bouleverser les formes d’engagement et à générer de nouveaux instruments structurant les interactions aux différents niveaux de responsabilité. Notre contribution propose d’approfondir certaines dimensions mises en avant dans le paradigme de la « Société du Risque » pour les confronter aux nouvelles pratiques d’engagement collectif et de régulation publique observées au cours des dernières années en Région wallonne, pour tester dans quelle mesure le questionnement propre à la modernité réflexive peut contribuer à l’intelligibilité des transformations socio-politiques actuelles.

In both Belgium and Canada, federalism is a hot and important topic. In order to explore the federal perceptions and preferences of the citizens in these two federations, four citizens’ meetings or assemblies are organised: two in Belgium (in Liège, Wallonia, in French, and in Antwerp, Flanders, in Dutch), and two in Canada (in Montreal, Quebec, in French, and in Kingston, Ontario, in English). During a whole day, sixty citizens are gathered to discuss with four experts and in small groups about the federalism in their country. The organisation and the methodology of the meetings are inspired from both citizens’ assemblies and deliberative polls. The first meeting took place at the Université de Liège, on September 29, 2007. The preliminary analyses of the qualitative and quantitative data collected during the nine hours long exchanges are presented in this paper. The first analyses shed light on the relations between the federal perceptions and preferences of French-speaking Belgian citizens. The preliminary results emphasise the diversity of knowledge, attitudes and opinions on Belgian federalism and highlight the contrast between these perceptions and preferences and the federal reality of Belgium as well as its possible evolution. The second meeting took place at the Université de Montréal, on March 15, 2008 and will be followed, respectively in June and November 2008, by the meetings in Kingston and in Antwerp. [less ▲]

While studying the influence of human proximity on the ecology of pigtail macaques, a species not well documented in continental Thailand, we collected data on ranging and foraging behaviours of a troop of Macaca nemestrina leonina living in the surroundings of Khao Yai National park tourist centre. We present here data suggesting a role as seed dispersers for the pigtails, role which has not been considered yet when analysing the importance of the frugivorous community in forest regeneration. Such a role might be however expected based on the highly frugivorous diet of the macaques, the presence of cheek pouches, and the relatively long distance they travel daily. The studied troop counts about 40 individuals, with 3 adult males for 9 adult females, and occupies a 100 ha home range with sleeping sites close to the tourist facilities. Macaques spent about 30% of their days in primary forests, and more than 60 percent in secondary forest and open areas. They consume a certain proportion of human food (6.4%), but spend most time foraging for wild food in the surrounding forest. Fruits count for an important part of their diet (76%) and, indeed, the faeces analysis reveals the presence of a high number of seeds, which size ranges up to above 15mm. Their viability was assessed using the cut-test and Tetrazolium immersion, showing a high percentage of viable seeds in the samples. Three series of seeds (defecated, spat, and control seeds) placed in germination boxes reached a high germination rate, with no uniform significant differences between defecated, spat and control seeds. Seeds without pulp, a frequent case when macaques reject them after transport and processing, seem to be more likely to germinate than seeds rejected with their pulp directly under the parent tree. These results suggest altogether that pigtail macaques are potential seed dispersers, an important factor in regard of their regular use of degraded habitat zones. [less ▲]

Based on an extensive HST FUV image database obtained between 1997 and 2007, we have studied the morphology and brightness of the equatorward diffuse auroral emissions in both Jovian hemispheres. The emissions are wider and brighter on the dusk side than on the dawn and they often form multiple discrete arcs parallel to the main oval. What could be the origin of these equatorward diffuse emissions and their local time variations is still unclear. Galileo observations have shown changes in the electron pitch angle distributions between the inner and middle magnetosphere of Jupiter (10 to 17 RJ ) which could be associated with auroral emissions, without the need of field aligned currents. We derive the electron precipitation flux for the first time in a global scale, based on Galileo electron measurements between 10 and 17 RJ . We magnetically map this region in the ionosphere and compare the derived energy flux with the brightness of the diffuse emissions. We discuss the possibility that the energetic particle distribution in the middle magnetosphere could account for the multiple structured equatorward diffuse emissions and their local time variations.

We have analyzed more than 1000 HST/ACS images of Jupiter’s ultraviolet auroral emission in the northern hemisphere. A systematic planet center finding algorithm made it possible to infer reliable and consistent jovicentric location of the auroral footprints of Io, Europa and Ganymede. These footprints form reference contours which provide an absolute magnetic mapping from the ionosphere of Jupiter to the equatorial plane, independent of any magnetic field model. So far, the VIP4 magnetic field model is the most accurate in terms of fitting the auroral emissions. However, it cannot reproduce the distorted shape of the satellites UV footpaths in the “kink region” in the northern ionosphere between S3 longitudes 80 ̊-150 ̊. We show that the model is significantly improved by decreasing the VIP4 surface magnetic field in the kink region and by adding a localized dipolar perturbation field beneath the surface. [less ▲]

The Morlet wavelet is applied to air temperature time series obtained from several weather stations and reveals the existence of a period cycle of 20-30 months since 1950, with an estimated amplitude of 0.5 C. The origin of this period is investigated by computing the scale spectra associated to the principal indices that characterize air mass flows in the troposphere and the stratosphere, as well as the signals related to the sunspot number and the solar flux. Each analysed signal shows this period of approximatively 2.5 years. This suggests that the 2.5 years-cycle could be resulted from the solar activity. [less ▲]
