Cette situation d’expérienciation structurée s’adresse à un grand groupe (une trentaine de personnes). L’exercice vise à permettre aux participants d’expérimenter la conduite d’une négociation dans une situation conflictuelle. Elle a pour objectifs principaux d’aider les participants à développer d’une lecture systémique et stratégique des situations conflictuelles en organisation, tout en les sensibilisant participants à la problématique de l’intervention en organisation, sa dynamique, sa complexité et ses difficultés. La situation se base sur le cas de Jérémy, un employé d’une grande surface commerciale qui a émis un témoignage télévisé, s’estimant victime de harcèlement de la part de sa hiérarchie. Au lendemain de la diffusion dudit témoignage, qui réveille différentes situations problématiques sur les plans personnel, interpersonnel et organisationnel, l’ensemble des acteurs de l’organisation, dont une équipe de consultants, sont mobilisés autour de la situation.

Grouped data occur frequently in practice, either because of limited resolution of instruments, or because data have been summarized in relatively wide bins. A combination of the composite link model with roughness penalties is proposed to estimate smooth densities from such data in a Bayesian framework. A simulation study is used to evaluate the performances of the strategy in the estimation of a density, of its quantiles and rst moments. Two illustrations are presented: the rst one involves grouped data of lead concentrations in the blood and the second one the number of deaths due to tuberculosis in The Netherlands in wide age classes.

Two hypotheses have been proposed to explain the origin of marine isotope stage (MIS) 11 deposits in small Bermudian caves at þ21 m above modern sea level: (1) a þ21 m MIS 11 eustatic sea-level highstand, and (2) a MIS 11 mega-tsunami event. Importantly, the foraminifera reported in these caves have yet to be critically evaluated within a framework of coastal cave environments. After statistically comparing foraminifera in modern Bermudian littoral caves and the MIS 11 Calonectris Pocket A (þ21 m cave) to the largest available database of Bermudian coastal foraminifera, the assemblages found in modern littoral caves – and Calonectris Pocket A – cannot be statistically differentiated from lagoons. This observation is expected considering littoral caves are simply sheltered extensions of a lagoon environment in the littoral zone, where typical coastal processes (waves, storms) homogenize and rework lagoonal, reefal, and occasional planktic taxa. Fossil protoconchs of the Bermudian cave stygobite Caecum caverna were also associated with the foraminifera. These results indicate that the MIS 11 Bermudian caves are fossil littoral caves (breached flank margin caves), where the total MIS 11 microfossil assemblage is preserving a signature of coeval sea level at þ21 m. Brackish foraminifera (Polysaccammina, Pseudothurammina) and anchialine gastropods (w95%, >300 individuals) indicate a brackish anchialine habitat developed in the elevated caves after the prolonged littoral environmental phase. The onset of sea-level regression following the þ21 m highstand would first lower the ancient brackish Ghyben-Herzberg lens (<0.5 m) and flood the cave with brackish water, followed by drainage of the cave to create a permanent vadose environment. These interpretations of the MIS 11 microfossils (considering both taphonomy and paleoecology) are congruent with the micropaleontological, hydrogeological and physical mechanisms influencing modern Bermudian coastal cave environments. In conclusion, we reject the mega-tsunami hypothesis, concur with the þ21 m MIS 11 eustatic sea-level hypothesis, and reiterate the need to resolve the disparity between global marine isotopic records and the physical geologic evidence for sea level during MIS 11.

This paper addresses the problem of centralized optimization of an interconnected power system partitioned into several regions controlled by different transmission system operators (TSOs). It is assumed that those utilities have agreed to transferring some of their competencies to a centralized control center, which is in charge of setting the control variables in the entire system to satisfy every utility’s individual objective. This paper proposes an objective method for centralized optimization of such multi-TSO power systems, which relies on the assumption that each TSO has a real-valued optimization function focusing on its control area only. This method is illustrated on the IEEE 118 bus system partitioned into three TSOs. It is applied to the optimal reactive power dispatch problem, where the control variables are the voltage settings for generators and compensators. After showing that the method has some properties of fairness, namely freedom from envy, efficiency, accountability, and altruism, we emphasize its robustness with respect to certain biased behavior of the different TSOs.

The study was conducted at the Rukoko station located at 21 km North-Western of Bujumbura in the Imbo natural region, in the South of Rusizi River. The objective was to assess the effects of year of lactation, genetic group, lactation length, season and parity on the Daily Milk Yield (DMY) of Jersey (J) x Sahiwal (S) x Ankole (A) crossed cows. Milk yields were obtained from cows that have been both Suckled and Milked (SM) or only Milked (M). Data were analyzed using the procedure GLM in SAS on SM and M cows, separately. All factors affected significantly DMY (p<0.001). A significant increase was observed from 1989-1991 due to the improvement of management techniques. During this period, the production raised from 10.07 +/- 0.22 L-11.50 +/- 0.17 L day(-1) for SM cows. Unfortunately, the 1993 civilian war destabilized the managerial techniques and consequently, the milk production decreased. Highest milk yields were observed in crossed cows with 50% of Jersey and 50% of Sahiwal inheritances. Peak yields occurred at the 43rd (12.67 +/- 0.42 L) and 56th (6.42 +/- 0.45 L) days in milk for SM and M cows, respectively. Milk production was significantly higher in January (11.04 +/- 0.23 L day(-1)), in the middle of the rainy season, than in July (7.02 +/- 0.18 L day(-1)), in the middle of the dry season. Milk yield in SM cows increased from 8.15 +/- 0.17 L-9.46 +/- 0.16 L day(-1) during the 1st and the 2nd lactation, respectively. [less ▲]

New major advances may be expected in a near future regarding the use of monoclonal antibodies (mAb), mainly thanks to the remarkable progress in biotechnology and the better knowledge of cellular homeostasis. The concept of antibody-targeted drugs relies upon the use of mAbs as vectors capable of specifically delivering at targeted cells (i.e. tumours) other active agents that could exert locally a cytotoxic effect (radioisotope, toxin, enzyme, drug). Other approaches will also be concidered such as the development and use of bispecific mAbs, intracellular mAbs or fragments of mAbs. These novel original approaches open promising therapeutic prospects. However, in many cases, their real interest in terms of "efficacy-safety-cost" ratio remains to be demonstrated as compared to other classical therapeutic approaches. [less ▲]

Hidradenitis suppurativa is a chronic and debilitating inflammatory disease. It presents as recurrent abcesses, sinus tracts and scarring. The condition usually develops in the axillae and groins, and more rarely involves the breasts, perineum and buttocks. There are many myths around hidradenitis suppurativa including its origin and pathomechanisms. Some antibiotics as well as corticosteroids and other immune downregulators are porly effective in this stubborn condition. By contrast, TNF-α antagonists appear promising. Radical surgery is another effective option. [less ▲]

Purpose: The Gastro-Intestinal Working Party of the EORTC Radiation Oncology Group (GIWP-ROG) developed guidelines for target volume definition in neoadjuvant radiation of adenocarcinomas of the gastroesophageal junction (GEJ) and the stomach. Methods and materials: Guidelines about the definition of the clinical target volume (CTV) are based on a systematic literature review of the location and frequency of local recurrences and lymph node involvement in adenocarcinomas of the GEJ and the stomach. Therefore, MEDLINE was searched up to August 2008. Guidelines concerning prescription, planning and treatment delivery are based on a consensus between the members of the GIWP-ROG. Results: In order to support a curative resection of GEJ and gastric cancer, an individualized preoperative treatment volume based on tumour location has to include the primary tumour and the draining regional lymph nodes area. Therefore we recommend to use the 2nd English Edition of the Japanese Classification of Gastric Carcinoma of the Japanese Gastric Cancer Association which developed the concept of assigning tumours of the GEJ and the stomach to anatomically defined sub-sites corresponding respectively to a distinct lymphatic spread pattern. Conclusion: The GIWP-ROG defined guidelines for preoperative irradiation of adenocarcinomas of the GEJ and the stomach to reduce variability in the framework of future clinical trials. © 2009 Elsevier Ireland Ltd.

The capability of a new multitracking system to track a large number of unmarked fish (up to 100) is evaluated. This system extrapolates a trajectory from each individual and analyzes recorded sequences that are several minutes long. This system is very efficient in statistical individual tracking, where the individual’s identity is important for a short period of time in comparison with the duration of the track. Individual identification is typically greater than 99%. Identification is largely efficient (more than 99%) when the fish images do not cross the image of a neighbor fish. When the images of two fish merge (occlusion), we consider that the spot on the screen has a double identity. Consequently, there are no identification errors during occlusions, even though the measurement of the positions of each individual is imprecise. When the images of these two merged fish separate (separation), individual identification errors are more frequent, but their effect is very low in statistical individual tracking. On the other hand, in complete individual tracking, where individual fish identity is important for the entire trajectory, each identification error invalidates the results. In such cases, the experimenter must observe whether the program assigns the correct identification, and, when an error is made, must edit the results. This work is not too costly in time because it is limited to the separation events, accounting for fewer than 0.1% of individual identifications. Consequently, in both statistical and rigorous individual tracking, this system allows the experimenter to gain time by measuring the individual position automatically. It can also analyze the structural and dynamic properties of an animal group with a very large sample, with precision and sampling that are impossible to obtain with manual measures. [less ▲]

The partial pressure of CO2 (pCO2) and dissolved inorganic carbon (DIC) were monitored in shallow coastal waters located inside and outside giant kelp beds (Macrocystis pyrifera) located in the Kerguelen Archipelago (Southern Ocean). Photosynthesis and respiration by microplankton and kelp lead to marked pCO2 and DIC diel cycles. Daily variations of pCO2 and DIC are significant in the spring and summer, but absent in the winter, reflecting the seasonal cycle of biological activity in the kelp beds. If the kelp beds seem to favour the onset of phytoplankton blooms, most of the primary production inside the kelp beds is due to the kelp itself. The primary production of Macrocystis kelp beds in the Sub-Antarctic high-nutrient, low-chlorophyll (HNLC) waters off the Kerguelen Archipelago is elevated and closely linked to light availability. This production is significant from October to March and reaches its climax in December at the solar radiation maximum. [less ▲]

In the eubacterial cell, the peptidoglycan is perpetually hydrolyzed throughout the cell cycle by different enzymes such as lytic transglycosylases, endopeptidases, and amidases. In Escherichia coli, four N-acetylmuramoyl-l-alanine amidases, AmiA, -B, -C, and -D, are present in the periplasm. AmiA, -B, and -C are soluble enzymes, whereas AmiD is a lipoprotein anchored in the outer membrane. To determine more precisely the specificity and the kinetic parameters of AmiD, we overproduced and purified the native His-tagged AmiD in the presence of detergent and a soluble truncated form of this enzyme by removing its signal peptide and the cysteine residue responsible for its lipidic anchorage. AmiD is a zinc metalloenzyme and is inactivated by a metal chelator such as EDTA. Native His-tagged and truncated AmiD hydrolyzes peptidoglycan fragments that have at least three amino acids in their peptide chains, and the presence of an anhydro function on the N-acetylmuramic acid is not essential for its activity. The soluble truncated AmiD exhibits a biphasic kinetic time course that can be explained by the inactivation of the enzyme by the substrate. This behavior highlights a new strategy to inhibit this class of enzymes. [less ▲]
