La manière dont certains médias, hommes politiques, représentants d'institutions internationales, intellectuels,... des quatre coins de la planète parlent de la globalisation, a largement contribué à répandre l'idée erronée qu'il s'agit d'un phénomène nouveau et inéluctable qui s'impose comme par enchantement à l'ensemble des sociétés du globe dès le début des années 1990, c'est-à-dire au lendemain de l'effondrement du bloc de l'Est. Cette manière de concevoir la globalisation a grandement contribué à la personnifier, faisant d'elle un sujet d'action invulnérable dont les interventions seraient plus que redoutables face auxquelles tout gouvernement serait impuissant. Une telle vision des choses fausse la réalité. En effet, ces schémas préétablis à caractère idéologique évacuent toute possibilité de concevoir la globalisation comme la conséquence de choix politiques. Il n'est pas possible de comprendre la globalisation et les contraintes économiques qu'elle engendre uniquement par le simple biais de l'évolution des modes de production et du progrès des échanges économiques. Il faut également tenir compte du fait que la globalisation procède d'une histoire. Autrement dit, elle s'insère dans un environnement politique et social marqué par des conflits, par des rapports de pouvoir et d'hégémonie, par des hiérarchies sociales et des liens de dépendance politique. La globalisation est donc aussi le résultat de choix politiques. [less ▲]

Le terme de « métaphysique » ne se lit pas chez Aristote. Les livres rassemblés sous ce titre ne cessent d'interroger leurs lecteurs quant à leur unité. La science ainsi désignée, enfin, semble contrevenir aux règles communes de la scientificité aristotélicienne. Désigner Aristote comme le « fondateur de la métaphysique » fait dès lors problème. L'hypothèse du présent travail est que cette fondation engage l'œuvre des commentateurs d'Aristote, au premier chef desquels se situe Alexandre d'Aphrodise. L'Exégète par excellence ouvre la possibilité de « faire de la métaphysique » sans que cela signifie seulement commenter Aristote. Alexandre travaille en effet à faire de la Métaphysique un livre et à instituer la métaphysique une science une. Selon l'Aphrodisien, la métaphysique est cette science à la fois universelle et première, à la fois science modèle et fondatrice des autres sciences. Elle s'articule en trois programmes principaux : l'étude générale de l'étant en tant qu'étant, celle de la substance et celle enfin de la cause première. Ces trois programmes sont distincts, mais coordonnés et suffisamment proches pour ne pas pouvoir être étudiés par une autre science, ni éclatés entre diverses sciences. Ils progressent à chaque fois par un passage d'une généralité à son maximum et sa cause. Ainsi la substance est-elle cause de l'être des autres étants et étant au maximum. Ainsi la cause première est-elle intelligible au plus haut point et cause de l'intelligibilité du monde. L'Exégète offre une interprétation forte de l'unité de la Métaphysique et de celle de la science correspondante. C'est dans et par cette reprise que les écrits du Stagirite sont devenus proprement fondateurs. [less ▲]

L’apparition de la méthode phénoménologique est indissociable d’un vaste programme d’analyse descriptive qui a été mis en place dans l’école de Franz Brentano. Ce programme, qui contraste fortement avec le programme d’explication externaliste prédominant en philosophie de l’esprit, consiste à décrire les actes et les états mentaux tels qu’ils sont vécus (pour ainsi dire « de l’intérieur »), c’est-à-dire à les décomposer en leurs éléments constitutifs et à saisir leur mode de liaison. J’exposerai la contribution de Brentano sur ce point, en focalisant mon attention sur la question de l’unité du mental, puis j’avancerai quelques raisons pour lesquelles le programme analytique brentanien me semble devoir être poursuivi à l’heure actuelle. Je suggérerai notamment qu’il jette un éclairage nouveau sur le rejet des propriétés non représentationnelles de l’expérience (le rejet des « purs qualia ») et, plus généralement, sur le problème de l’individuation des états mentaux.

Dans un article récent, D. Giovannangeli mettait en évidence, à partir d’un identique découplage de l’homme et de la finitude, l’importance du Kantbuch de Heidegger pour Les Mots et les choses ; il suggérait finalement que l’ontologie implicite de l’archéologie foucaldienne ne serait pas sans analogie avec l’histoire de l’Être. Axant le rapport de Foucault à Heidegger sur leur commun rejet de l’anthropologie kantienne, le présent article explore cette suggestion en plusieurs temps. Soulignant d’abord l’ambivalence de Les Mots et les choses tant à l’égard de Heidegger que de Kant, il revient sur l’importance de Heidegger dans les textes pré-archéologiques de Foucault, qu’ils concernent Binswanger ou, dans sa thèse complémentaire, Kant lui-même. Prenant la mesure du rôle essentiel d’intercesseur joué, entre Heidegger et Foucault, par le livre L’Héritage kantien et la révolution copernicienne (Vuillemin), il met finalement en évidence, autour du problème du sujet éthique, l’incompatibilité de la dernière pensée de Foucault et de la pensée de la vérité de l’Être.

This study investigated the percentage of carbohydrate utilization than can be accounted for by glucose ingested during exercise performed after the ingestion of the potent lipolysis inhibitor Acipimox. Six healthy male volunteers exercised for 3 h on a treadmill at about 45% of their maximal oxygen uptake, 75 min after having ingested 250 mg of Acipimox. After 15-min adaptation to exercise, they ingested either glucose dissolved in water, 50 g at time 0 min and 25 g at time 60 and 120 min (glucose, G) or sweetened water (control, C). Naturally labelled [13C]glucose was used to follow the conversion of the ingested glucose to expired-air CO2. Acipimox inhibited lipolysis in a similar manner in both experimental conditions. This was reflected by an almost complete suppression of the exercise-induced increase in plasma free fatty acid and glycerol and by an almost constant rate of lipid oxidation. Total carbohydrate oxidation evaluated by indirect calorimetry, was similar in both experimental conditions [C, 182, (SEM 21); G, 194 (SEM 16) g.3 h-1], as was lipid oxidation [C, 57 (SEM 6); G, 61 (SEM 3) g.3 h-1]. Exogenous glucose oxidation during exercise G, calculated by the changes in 13C:12C ratio of expired air CO2, averaged 66 (SEM 5) g.3 h-1 (19% of the total energy requirement). Consequently, endogenous carbohydrate utilization was significantly smaller after glucose than after placebo ingestion: 128 (SEM 18) versus 182 (SEM 21) g.3 h-1, respectively (P < 0.05). Symptoms of intense fatigue and leg cramps observed with intake of sweet placebo were absent with glucose ingestion.(ABSTRACT TRUNCATED AT 250 WORDS) [less ▲]

Pot experiments were conducted in the laboratory with lime applications to decrease trace elements in Chinese cabbage produced on soils contaminated by trace ele- ments in the intensive periurban area in Chenggong County, Yunnan Province, China. Soil was an acidic loam developed from lacustrine-alluvial deposits. Results showed the following: (1) soil pH increased from 5.3 to 6.5, and acetic-acid-extractable trace-element contents and ratio of acetic-acid-extractable trace-element contents in treatments relative to those in the control (RRCT) decreased with increased rate of lime application. (2) Chinese cabbage more easily absorbed acetic-acid-extractable trace elements. Enrichment coefficients related to trace-element availability (AEC) of lead (Pb; mean: 3.3) and zinc (Zn; mean: 5.8) were stable, and the AEC of cadmium (Cd) was 1.8–2.0 with increased lime application rate. (3) Trace-element contents in Chinese cabbage decreased, and biomass of Chinese cabbage increased, with lime application rate. Trace-element contents in soil solution and acetic-acid-extractable trace-element contents can predict trace-element contents in Chinese cabbage, especially for soil solution. Lime quality and trace-element accumulation in Chinese cabbage should be taken into account when amendment is added to in situ soil contaminated with trace elements. [less ▲]

The available energy (AE), driving the turbulent fluxes of sensible heat and latent heat at the earth surface, was estimated at four partly complex coniferous forest sites across Europe (Tharandt, Germany; Ritten/Renon, Italy; Wetzstein, Germany; Norunda, Sweden). Existing data of net radiation were used as well as storage change rates calculated from temperature and humidity measurements to finally calculate the AE of all forest sites with uncertainty bounds. Data of the advection experiments MORE II (Tharandt) and ADVEX (Renon, Wetzstein, Norunda) served as the main basis. On-site data for referencing and cross-checking of the available energy were limited. Applied cross checks for net radiation (modelling, referencing to nearby stations and ratio of net radiation to global radiation) did not reveal relevant uncertainties. Heat storage of sensible heat J (H), latent heat J (E), heat storage of biomass J (veg) and heat storage due to photosynthesis J (C) were of minor importance during day but of some importance during night, where J (veg) turned out to be the most important one. Comparisons of calculated storage terms (J (E), J (H)) at different towers of one site showed good agreement indicating that storage change calculated at a single point is representative for the whole canopy at sites with moderate heterogeneity. The uncertainty in AE was assessed on the basis of literature values and the results of the applied cross checks for net radiation. The absolute mean uncertainty of AE was estimated to be between 41 and 52 W m(-2) (10-11 W m(-2) for the sum of the storage terms J and soil heat flux G) during mid-day (approximately 12% of AE). At night, the absolute mean uncertainty of AE varied from 20 to about 30 W m(-2) (approximately 6 W m(-2) for J plus G) resulting in large relative uncertainties as AE itself is small. An inspection of the energy balance showed an improvement of closure when storage terms were included and that the imbalance cannot be attributed to the uncertainties in AE alone. [less ▲]

The world is facing a historical increase in energy demand and energy consumption. Renewable energy sources are considered as a solution to both environmental issues and increasing energy demand, but present high variability and low predictability. Variability and uncertainty are familiar aspects of all power systems. However, the increase of the share of renewable sources leads to new needs in terms of flexible resources. These resources can be provided by four different means: 1. Dispachable power plants (i.e with ramp up and ramp down capabilities) 2. Storage systems, mainly in the form of pumping stations. 3. Grid interconnections between countries 4. Demand side management. The present work focuses on the high voltage transmission grid, and assesses the amount of technical flexibility available to balance the fluctuations of Variable Renewable Energy (VRE) sources. The model is based on a dynamic programming unit commitment algorithm (i.e. accounting for each individual power plant on the grid) and focuses more particularly on the flexibility potential of power plants and of energy storage. The selected time resolution is one hour. Residual load curves are established on the basis of actual consumption for the year 2012 and on different scenarios of solar and wind penetration. The method is applied to the case of Belgium, based on actual disaggregated power consumption curves throughout the year, and on the current power generation park. Due to the difficulty to assess the flexible resource available through interconnections, the Belgian grid is considered isolated. It should also be noted that this work does not address the voltage stability issue: it focuses on balancing issues only (i.e. time constants varying between minutes and days). Simulation results show the VRE penetration potential is higher than usually considered. Bottlenecks therefore seems to be related to improper or inefficient market mechanisms, unable to take full profit of the technical flexible resource available. [less ▲]

We report acoustic measurements of popping bubbles during the collapsing of aqueous foams. The sound pattern is analyzed using classical methods of statistical physics. It is found that membrane rupture concerns a wide variety of situations: small and large membranes at the air/foam interface. Avalanches of popping bubbles are put into evidence. Time durations in between successive pops seem to be distributed on a universal power law. [less ▲]

Introduction: Children’s quality of life evaluation has specific methodological aspects. Objective: To examine the psychometric properties of the Portuguese version of the Child Quality of Life Systemic Inventory (CQLSI), which is based on an innovative conceptual and methodological approach to quality of life self-assessment, namely by being interactive and playful, having a psychometry which operates several scores and allowing an analysis of each domain of life. Methods: 120 Portuguese children, from 8 to 12 years old. Results: Internal consistency of the four scores of the CQLSI (State, Goal, Rank and Gap) is satisfactory; all scores have their own specificity. Data show convergent validity. On the other hand, no satisfactory factorial structure was found. Conclusion: Feasibility and psychometric adequacy of the CQLSI Portuguese version seems demonstrated. [less ▲]
