Perceptions de la performance et comportements de agents publics suisses dans un environnement en constante évolution

Alors que les modèles et notions de performance généralement analysés dans les recherches sont presque toujours ceux du management et des cadres dirigeants, cet article propose de s'arrêter sur la vision des employés, en l'occurrence des agents publics suisses. Il présente, à la lumière des réformes entreprises dans l'administration publique en Suisse, d'une part la conception générale qu'ont les agents publics de la performance du service public, et d'autre part leur perception de l'évolution des performances organisationnelle, individuelle, ainsi que celle en lien avec les prestations fournies aux bénéficiaires. L'analyse de la performance perçue est effectuée à travers la mise en évidence de l'existence de plusieurs mondes de référence auxquels se rapportent les agents publics lorsqu'ils parlent de leur travail. Les résultats révèlent la prégnance du monde industriel, devançant le monde civique qui, lui-même, relègue les mondes domestique et marchand respectivement en troisième et quatrième position. Un intérêt particulier est également accordé aux différents comportements, découlant des réformes du service public, qu'adoptent les agents publics, et aux liens qui pourraient exister entre ces comportements et les différents mondes de référence. Un mariage entre deux mondes, potentiellement contradictoires, semble se dessiner dans l'esprit des agents publics. Il pourrait constituer une réponse à une forme de crise identitaire, mise en avant par de nombreux spécialistes, provoquée par des injonctions contradictoires auxquelles sont soumis actuellement les agents publics.

Monte Carlo study of the relation between vacancy diffusion and domain growth in two-dimensional binary alloys

Domain growth in a two-dimensional binary alloy is studied by means of Monte Carlo simulation of an ABV model. The dynamics consists of exchanges of particles with a small concentration of vacancies. The influence of changing the vacancy concentration and finite-size effects has been analyzed. Features of the vacancy diffusion during domain growth are also studied. The anomalous character of the diffusion due to its correlation with local order is responsible for the obtained fast-growth behavior.

La prévalence des douleurs du dos et de ses facteurs de risque chez les citoyens suisses convoqués à leur recrutement en Suisse romande en 1985

L'objet de cette étude est d'estimer la prévalence des douleurs du racis chez les jeunes hommes convoqués pour la première fois à leur recrutement en Suisse romande en 1985. On s'intéresse donc aux douleurs présentes au moment du recrutement, mais également aux douleurs déjà révolues, puisqu'on sait qu'il s'agit d'une affection qui récidive facilement. Ceci est donc considéré comme un facteur de risque. D'autres facteurs de risque tels que le sport et la profession exercée seront analysés afin d'estimer leur influence sur la prévalence des cervico-dorso-lombalgies. [Auteur, p. 7]

Inter-relation between soybean yield and soil compaction under degraded pasture in Brazilian Savannah

The Cerrado (Brazilian Savannah) plays an important economic and financial role in the nation, since the pastures of this biome feed cattle for half of the domestic bovine meat productivity, and its agricultural fields produce a third of the country's grain. The variability and spatial dependence between the soil physical attributes and soybean yield were evaluated in a crop rotation planted on a degraded brachiaria pasture, on a dystroferric Red Latosol of an experimental farm of the State University of São Paulo (UNESP), in the 2005/2006 growing season. The linear and spatial correlations between these attributes were also studied, to determine conditions that would allow increased agricultural productivity. In the above pasture area, a grid was installed with 124 plots, spaced 10.0 x 10.0 m and 5.0 x 5.0 m apart, in a total area of 7,500 m². From the linear and spatial point of view, the high grain yield can be explained by the number of grains per plant and soil macroporosity. The high variability observed for most soil properties indicated that the crop - livestock integration system results in environmental heterogeneity of the soil.

Linear relation between deuteron matter radius and the scattering length

We explain the empirical linear relations between the triplet scattering length, or the asymptotic normalization constant, and the deuteron matter radius using the effective range expansion in a manner similar to a recent paper by Bhaduri et al. We emphasize the corrections due to the finite force range and to shape dependence. The discrepancy between the experimental values and the empirical line shows the need for a larger value of the wound extension, a parameter which we introduce here. Short-distance nonlocality of the n-p interaction is a plausible explanation for the discrepancy.

Defensive flexibility and its relation to symptom severity, depression, and anxiety.

Numerous studies have examined which individual defense mechanisms are related with mental health, and which are linked with psychopathology. However, the idea that a flexible use of defensive mechanisms is related to psychological wellbeing remained a clinical assumption, which this study sought to test empirically. A total of 62 (N = 62) outpatients participated in the study and were assessed with the Symptom Checklist-90R and the Social Adjustment Self-rated Scale. A subsample of 40 participants was further assessed using the Hamilton Depression (HAMD-21) and Anxiety scales (HAMA-21). The first therapy session of all participants was transcribed and rated using the Defense Mechanisms Ratings Scales (), and the Overall Defensive Functioning (ODF) score, which indicates the maturity of one's defensive functioning, was computed. An indicator of flexible use of defenses was also calculated based on the Gini Concentration C measure. Results showed that defensive flexibility, but not ODF, could predict anxiety scores. Symptom severity was predicted by both ODF and defensive flexibility, although in directions opposite to our predictions. Results suggest that defensive flexibility captures another aspect of an individual's functioning not assessed by the ODF, and that it is a promising new way of documenting defensive functioning.

Device for simultaneous measurement of the Peltier and Seebeck coefficients verification of the Kelvin relation

We have designed and built an experimental device, which we called a "thermoelectric bridge." Its primary purpose is simultaneous measurement of the relative Peltier and Seebeck coefficients. The systematic errors for both coefficients are equal with this device and manipulation is not necessary between the measurement of one coefficient and the other. Thus, this device is especially suitable for verifying their linear relation postulated by Lord Kelvin. Also, simultaneous measurement of thermal conductivity is described in the text. A sample is made up of the couple nickel¿platinum, taking measurements in the range of ¿20¿60°C and establishing the dependence of each coefficient with temperature, with nearly equal random errors ±0.2%, and systematic errors estimated at ¿0.5%. The aforementioned Kelvin relation is verified in this range from these results, proving that the behavioral deviations are ¿0.3% contained in the uncertainty ±0.5% caused by the propagation of errors

Défendre la démocratie directe : sur quelques arguments antidémocratiques des élites suisses

Plus que jamais, l'actualité mondiale ou nationale met en question le pouvoir du peuple. Là il se révolte avec fracas. Ici on le voit voter contre les autorités en place. Pour les uns il reconquiert sa liberté. Pour les autres il est aveugle et crée le désordre. Voici donc un livre sur le pouvoir. Dans la tradition de Benjamin Constant ou d'Alexis de Tocqueville, Antoine Chollet confère du souffle à l'examen des fondamentaux. Comment comprendre et articuler la liberté, l'égalité, la responsabilité, l'opposition entre une élite dite éclairée et les masses. En Suisse, quels sont les atouts exceptionnels, les dérives ou les illusions de la démocratie directe? Mal comprise elle est souvent confondue avec les libertés communales du Moyen Age. Ou admise avec des réserves suspectes. L'auteur en appelle à plus de rigueur et, fort de ses convictions, conclut par des appréciations sévères sur la politique suisse. Il décèle dans ses élites des tendances clairement antidémocratiques. Et inversement, il expose les raisons d'une confiance renforcée en l'institution même de la démocratie directe.

Oxygen consumption in collagenase-liberated rat adipocytes in relation to cell size and age.

Oxygen consumption of collagenase-liberated rat adipocytes was measured by two different techniques: a microspectrophotometric method using hemoglobin as indicator of respiration and a technique using the oxygen electrode. These two completely different techniques gave similar values for oxygen consumption. With the spectrophotometric method, the oxygen consumption of single fat cells was determined. A close positive correlation (r = greater than 0.90) between oxygen consumption and fat cell size was observed in each tissue examined. With the oxygen electrode technique, oxygen consumption of adipocyte suspensions from young (40 days, 180 g) and old (90 days, 480 g) rats was examined. Fat cells of the suspensions were separated into classes of different size by a flotation technique. A significant positive correlation between fat cell size and oxygen consumption was observed in both young (r = 0.88) and old (r = 0.95) rats. However, the slope was much steeper in young rats. At a cell weight of 0.1 microgram the oxygen consumption was 0.364 and 0.086 microL O2/10(6) cells/min-1 in young and old rats, respectively. In the literature, a number of separate metabolic pathways have been found to be related positively to fat cell size and negatively to age. We conclude that these scattered metabolic observations are in agreement with integrated data on energy expenditure as evaluated from oxygen consumption. Estimations of the energy expenditure of adipose tissue indicates that this tissue is responsible for about 1% and 0.5% of the total energy expenditure in young and old rats, respectively.
