Délégation de compétences et répartition des tâches au sein du conseil d'administration : rôles du conseil d'administration, de ses comités et de l'assemblée générale

Introduction générale : Depuis peu, la colère gronde au sein des actionnaires. Certains d'entre eux s'estiment écartés à tort de certaines décisions importantes et se plaignent de ne pouvoir exercer aucune influence sur la façon dont est gérée la société, dont ils sont pourtant propriétaires. Ce sentiment d'impuissance et même d'injustice est exacerbé par l'octroi, à certains dirigeants parfois peu scrupuleux, de rémunérations astronomiques et en décalage avec les résultats obtenus. Bien que l'assemblée générale soit, aux termes de l'art. 698 al. 1 CO, le pouvoir suprême de la société, les administrateurs et les directeurs donnent l'impression d'être omnipotents et exempts de toute responsabilité Certains actionnaires estiment en d'autres termes que les sociétés anonymes souffrent d'un manque de contrôle. Ce sentiment correspond-il à la réalité ? Notre étude tente de répondre à cette question en examinant l'éventuel rapport hiérarchique entre l'assemblée générale et le conseil d'administration, les devoirs de ce dernier, les conditions auxquelles il peut déléguer la gestion, enfin, la responsabilité de ses membres. Face à l'ampleur du sujet, nous avons été contraint d'effectuer des choix, forcément arbitraires. Nous avons décidé d'écarter la problématique des groupes de sociétés. De même, les législations sur les bourses, les banques et les fusions ne seront que mentionnées. Signalons enfin que certaines problématiques abordées par notre étude occupent actuellement le législateur. Nous avons dès lors tenu compte des travaux préparatoires effectués jusqu'à la fin de l'année 2008. Nous commencerons par étudier dans une première partie les relations et l'éventuel rapport hiérarchique entre l'assemblée générale, pouvoir suprême de la société, et le conseil d'administration, chargé d'exercer la haute direction et de gérer les affaires de la société. La détermination de leurs positions hiérarchiques respectives devrait nous permettre de savoir si et comment l'assemblée générale peut s'immiscer dans les compétences du conseil d'administration. Nous nous intéresserons ensuite à la gestion de la société, le législateur postulant qu'elle doit être conjointement exercée par tous les membres du conseil d'administration dans la mesure où elle n'a pas été déléguée. Or, comme un exercice conjoint par tous les administrateurs ne convient qu'aux plus petites sociétés anonymes, la gestion est très fréquemment déléguée en pratique. Nous examinerons ainsi les conditions formelles et les limites matérielles de la délégation de la gestion. Nous étudierons en particulier les portées et contenus respectifs de l'autorisation statutaire et du règlement d'organisation, puis passerons en revue la liste de compétences intransmissibles et inaliénables du conseil d'administration dressée par l'art. 716a al. 1 CO. Nous nous attarderons ensuite sur les différents destinataires de la délégation en insistant sur la flexibilité du système suisse, avant de considérer la problématique du cumul des fonctions à la tête de la société, et de nous demander si la gestion peut être déléguée à l'assemblée générale. Nous conclurons la première partie en étudiant la manière dont l'assemblée générale peut participer à la gestion de la société, et exposerons à cet égard les récentes propositions du Conseil fédéral. Dans une deuxième partie, nous constaterons que face à l'ampleur et à la complexité des tâches qui lui incombent, il est aujourd'hui largement recommandé au conseil d'administration d'une grande société de mettre en place certains comités afin de rationnaliser sa façon de travailler et d'optimiser ainsi ses performances. Contrairement aux développements menés dans la première partie, qui concernent toutes les sociétés anonymes indépendamment de leur taille, ceux consacrés aux comités du conseil d'administration s'adressent principalement aux sociétés ouvertes au public et aux grandes sociétés non cotées. Les petites et moyennes entreprises seraient toutefois avisées de s'en inspirer. Nous traiterons de la composition, du rôle et des tâches de chacun des trois comités usuels que sont le comité de contrôle, le comité de rémunération et le comité de nomination. Nous exposerons à cet égard les recommandations du Code suisse de bonne pratique pour le gouvernement d'entreprise ainsi que certaines règles en vigueur en Grande-Bretagne et aux Etats-Unis, états précurseurs en matière de gouvernement d'entreprise. L'étude des tâches des comités nous permettra également de déterminer l'étendue de leur propre pouvoir décisionnel. Nous aborderons enfin la problématique particulièrement sensible de la répartition des compétences en matière de rémunération des organes dirigeants. Notre troisième et dernière partie sera consacrée à la responsabilité des administrateurs. Nous exposerons dans un premier temps le système de la responsabilité des administrateurs en général, en abordant les nombreuses controverses dont il fait l'objet et en nous inspirant notamment des récentes décisions du Tribunal fédéral. Comme la gestion n'est que rarement exercée conjointement par tous les administrateurs, nous traiterons dans un deuxième temps de la responsabilité des administrateurs qui l'ont déléguée. A cet égard, nous nous arrêterons également sur les conséquences d'une délégation ne respectant pas les conditions formelles. Nous terminerons notre travail par l'étude de la responsabilité des administrateurs en rapport avec les tâches confiées à un comité de conseil d'administration. Comme le conseil d'administration a des attributions intransmissibles et inaliénables et que les principes d'un bon gouvernement d'entreprise lui recommandent de confier certaines de ces tâches à des comités spécialisés, il s'agit en effet de déterminer si et dans quelle mesure une répartition des tâches au sein du conseil d'administration entraîne une répartition des responsabilités.

Tearing and folding of the retinal internal limiting membrane associated with macular epiretinal membrane

PURPOSE: To describe the clinical and histologic features of a particular form of macular epiretinal membrane. METHODS: The charts of all patients operated for macular epiretinal membrane by a single surgeon (E.H.B.) between June 2001 and January 2005 were retrospectively reviewed. Patients with macular epiretinal membrane associated with tearing and folding of the internal limiting membrane (ILM) were identified and the following parameters were recorded when available: age, gender, best-corrected visual acuity before and after vitrectomy; optical coherence tomography; pre-, intra-, and postoperative macular status; intraoperative staining by indocyanine green; histology. RESULTS: Twenty-three of 268 eyes (8.6%) with macular epiretinal membrane were associated with tearing and folding of the ILM, forming a whitish prominent band on the surface of the retina. The mean age of the patients was 68.6 years with a significant female predominance (78.3%). The vitreous was completely detached in 21 eyes. After surgical peeling, the mean visual gain was 3.2 Early Treatment Diabetic Retinopathy Study lines. No recurrence was observed. CONCLUSION: Tearing and folding of the ILM was associated with macular epiretinal membranes in 8.6% of cases. The ILM was probably torn during posterior hyaloid detachment, but the pathogenesis has not been clearly elucidated. The surgeon should begin to peel the macular epiretinal membrane by grasping the folded ILM to ensure complete removal of the ILM together with the epiretinal membrane. The postoperative visual prognosis was good

EZ-IO(®) intraosseous device implementation in a pre-hospital emergency service: A prospective study and review of the literature.

INTRODUCTION: Intraosseous access is increasingly recognised as an effective alternative vascular access to peripheral venous access. We aimed to prospectively study the patients receiving prehospital intraosseous access with the EZ-IO(®), and to compare our results with those of the available literature. METHODS: Every patient who required an intraosseous access with the EZ-IO from January 1st, 2009 to December 31st, 2011 was included. The main data collected were: age, sex, indication for intraosseous access, localisation of insertion, success rate, drugs and fluids administered, and complications. All published studies concerning the EZ-IO device were systematically searched and reviewed for comparison. RESULTS: Fifty-eight patients representing 60 EZ-IO procedures were included. Mean age was 47 years (range 0.5-91), and the success rate was 90%. The main indications were cardiorespiratory arrest (74%), major trauma (12%), and shock (5%). The anterior tibia was the main route. The main drugs administered were adrenaline (epinephrine), atropine and amiodarone. No complications were reported. We identified 30 heterogeneous studies representing 1603 EZ-IO insertions. The patients' characteristics and success rate were similar to our study. Complications were reported in 13 cases (1.3%). CONCLUSION: The EZ-IO provides an effective way to achieve vascular access in the pre-hospital setting. Our results were similar to the cumulative results of all studies involving the use of the EZ-IO, and that can be used for comparison for further studies.

Ultraviolet optical and microstructural properties of MgF2 and LaF3 coatings deposited by ion-beam sputtering and boat and electron-beam evaporation

Single layers of MgF2 and LaF3 were deposited upon superpolished fused-silica and CaF2 substrates by ion-beam sputtering (IBS) as well as by boat and electron beam (e-beam) evaporation and were characterized by a variety of complementary analytical techniques. Besides undergoing photometric and ellipsometric inspection, the samples were investigated at 193 and 633 nm by an optical scatter measurement facility. The structural properties were assessed with atomic-force microscopy, x-ray diffraction, TEM techniques that involved conventional thinning methods for the layers. For measurement of mechanical stress in the coatings, special silicon substrates were coated and analyzed. The dispersion behavior of both deposition materials, which was determined on the basis of various independent photometric measurements and data reduction techniques, is in good agreement with that published in the literature and with the bulk properties of the materials. The refractive indices of the MgF2 coatings ranged from 1.415 to 1.440 for the wavelength of the ArF excimer laser (193 nm) and from 1.435 to 1.465 for the wavelength of the F2 excimer laser (157 nm). For single layers of LaF3 the refractive indices extended from 1.67 to 1.70 at 193 nm to ~1.80 at 157 nm. The IBS process achieves the best homogeneity and the lowest surface roughness values (close to 1 nmrms) of the processes compared in the joint experiment. In contrast to MgF2 boat and e-beam evaporated coatings, which exhibit tensile mechanical stress ranging from 300 to 400 MPa, IBS coatings exhibit high compressive stress of as much as 910 MPa. A similar tendency was found for coating stress in LaF3 single layers. Experimental results are discussed with respect to the microstructural and compositional properties as well as to the surface topography of the coatings.

Ambulances et SMUR en cas d'urgences vitales au cabinet médical: implications pour la formation et l'équipement du médecin de premier recours

Introduction: Tout praticien est confronté quotidiennement à des urgences. Parmi celles-ci, les urgences vitales peuvent avoir des conséquences majeures pour le patient et pour le praticien. Le but de cette analyse est de déterminer la fréquence de survenue des urgences vitales au cabinet médical qui motivent l'intervention d'une ambulance, avec ou sans médicalisation par un SMUR (Service Mobile d'Urgence et de Réanimation) et d'en évaluer des conséquences en terme de mise en place de procédures, d'équipements ainsi que de formations post-graduée ou continue spécifiques. Matériel et méthode: Etude rétrospective des fiches d'intervention pré-hospitalière des services d'ambulances et des missions des SMUR du canton de Vaud (650'000 habitants) entre 2003 et 2006 pour les missions dont la prise en charge d'un patient a eu lieu dans le cadre d'un cabinet médical. Résultats: Entre 2003 et 2006, 2'224 interventions avec ambulances ont eu lieu dans un des 1'655 cabinet médical vaudois (= 2,3% de l'ensemble des missions) et, dans >90% des cas, dans un délai de 20 minutes. Parmi les interventions, on relève les urgences suivantes (n =, % des interventions): cardio-vasculaires: 755 (= 33,9%), dont 17 arrêts cardio-respiratoires (ACR); respiratoires: 165 (= 7,4%); neurologiques: 138 (= 6,2%); psychiatriques: 129 (= 5,8%); traumatologiques: 475 (= 21,4%), dont 261 (= 54,9%) concernent les extrémités; diverses: 205 (= 9,5%); autres: 359 (= 16,1%). Sur ces interventions, 634 (= 28,5%) ont bénéficié d'une médicalisation par un SMUR, dont 440 (= 70% des missions SMUR au cabinet) pour des urgences cardio-vasculaires. Il y a eu 6 cas de décès au cabinet. Discussion: Les urgences cardio-vasculaires au cabinet représentent un tiers des interventions faisant appel à une ambulance, mais plus des deux tiers des interventions nécessitant une médicalisation, soit plus que pour les autres sites d'interventions médicalisées dans la communauté (46%). Conclusions: Les urgences vitales au cabinet médical ne sont pas négligeable, peuvent avoir des conséquences lourdes (ACR, décès) et perturber significativement son fonctionnement. Dès lors, une formation appropriée tant pour le médecin que pour son personnel, ainsi qu'un équipement adéquat (par ex. salle équipée avec défibrillateur, appareil d'aérosol, attelles pour les extrémités) devraient être encouragés et généralisés auprès du corps médical.

Arbuscular mycorrhizal fungal communities and soil aggregation as affected by cultivation of various crops during the sugarcane fallow period

Management systems involving crop rotation, ground cover species and reduced soil tillage can improve the soil physical and biological properties and reduce degradation. The primary purpose of this study was to assess the effect of various crops grown during the sugarcane fallow period on the production of glomalin and arbuscular mycorrhizal fungi in two Latosols, as well as their influence on soil aggregation. The experiment was conducted on an eutroferric Red Latosol with high-clay texture (680 g clay kg-1) and an acric Red Latosol with clayey texture (440 g kg-1 clay) in Jaboticabal (São Paulo State, Brazil). A randomized block design involving five blocks and four crops [soybean (S), soybean/fallow/soybean (SFS), soybean/millet/soybean (SMS) and soybean/sunn hemp/soybean (SHS)] was used to this end. Soil samples for analysis were collected in June 2011. No significant differences in total glomalin production were detected between the soils after the different crops. However, total external mycelium length was greater in the soils under SMS and SHS. Also, there were differences in easily extractable glomalin, total glomalin and aggregate stability, which were all greater in the eutroferric Red Latosol than in the acric Red Latosol. None of the cover crops planted in the fallow period of sugarcane improved aggregate stability in either Latosol.

Soil uses during the sugarcane fallow period: influence on soil chemical and physical properties and on sugarcane productivity

The planting of diversified crops during the sugarcane fallow period can improve the chemical and physical properties and increase the production potential of the soil for the next sugarcane cycle. The primary purpose of this study was to assess the influence of various soil uses during the sugarcane fallow period on soil chemical and physical properties and productivity after the first sugarcane harvest. The experiment was conducted in two areas located in Jaboticabal, São Paulo State, Brazil (21º 14' 05'' S, 48º 17' 09'' W) with two different soil types, namely: an eutroferric Red Latosol (RLe) with high-clay texture (clay content = 680 g kg-1) and an acric Red Latosol (RLa) with clayey texture (clay content = 440 g kg-1). A randomized block design with five replications and four treatments (crop sequences) was used. The crop sequences during the sugarcane fallow period were soybean/millet/soybean, soybean/sunn hemp/soybean, soybean/fallow/soybean, and soybean. Soil use was found not to affect chemical properties and sugarcane productivity of RLe or RLa. The soybean/millet/soybean sequence improved aggregation in the acric Latosol.

Cardiovascular risk estimation and eligibility for statins in primary prevention comparing different strategies

Recommendations for statin use for primary prevention of coronary heart disease (CHD) are based on estimation of the 10-year CHD risk. It is unclear which risk algorithm and guidelines should be used in European populations. Using data from a population-based study in Switzerland, we first assessed 10-year CHD risk and eligibility for statins in 5,683 women and men 35 to 75 years of age without cardiovascular disease by comparing recommendations by the European Society of Cardiology without and with extrapolation of risk to age 60 years, the International Atherosclerosis Society, and the US Adult Treatment Panel III. The proportions of participants classified as high-risk for CHD were 12.5% (15.4% with extrapolation), 3.0%, and 5.8%, respectively. Proportions of participants eligible for statins were 9.2% (11.6% with extrapolation), 13.7%, and 16.7%, respectively. Assuming full compliance to each guideline, expected relative decreases in CHD deaths in Switzerland over a 10-year period would be 16.4% (17.5% with extrapolation), 18.7%, and 19.3%, respectively; the corresponding numbers needed to treat to prevent 1 CHD death would be 285 (340 with extrapolation), 380, and 440, respectively. In conclusion, the proportion of subjects classified as high risk for CHD varied over a fivefold range across recommendations. Following the International Atherosclerosis Society and the Adult Treatment Panel III recommendations might prevent more CHD deaths at the cost of higher numbers needed to treat compared with European Society of Cardiology guidelines.

How demography, life history, and kinship shape the evolution of genomic imprinting.

How phenomena like helping, dispersal, or the sex ratio evolve depends critically on demographic and life-history factors. One phenotype that is of particular interest to biologists is genomic imprinting, which results in parent-of-origin-specific gene expression and thus deviates from the predictions of Mendel's rules. The most prominent explanation for the evolution of genomic imprinting, the kinship theory, originally specified that multiple paternity can cause the evolution of imprinting when offspring affect maternal resource provisioning. Most models of the kinship theory do not detail how population subdivision, demography, and life history affect the evolution of imprinting. In this work, we embed the classic kinship theory within an island model of population structure and allow for diverse demographic and life-history features to affect the direction of selection on imprinting. We find that population structure does not change how multiple paternity affects the evolution of imprinting under the classic kinship theory. However, if the degree of multiple paternity is not too large, we find that sex-specific migration and survival and generation overlap are the primary factors determining which allele is silenced. This indicates that imprinting can evolve purely as a result of sex-related asymmetries in the demographic structure or life history of a species.

Partial trisomy 20q in a newborn with dextrocardia.

A female newborn is reported with dextrocardia and a partial trisomy 20q, derived from a t(2;20) paternal translocation. The most discriminating findings of the condition include brachycephaly, bulging forehead, deep set eyes, short nose, large ears, dimpled chin, short neck and a heart defect. Previously reported patients with this rare chromosomal anomaly are reviewed.

Climatic and land use changes in the NW of Iberian Peninsula recorded in a 1,500-year record from Lake Sanabria

L'estudi de diversos descriptors paleoambientals com ara el pol·len, les diatomees i la sedimentologia, realitzat en sediments procedents del llac de Sanabria (NO de la península Ibèrica), ha aportat informació sobre les oscil·lacions climàtiques atribuïdes als períodes càlids tardoromà i medieval, així com a la petita edat del gel. Entre els anys 440 i 950 dC, el clima es caracteritzà per temperatures suaus i un règim de precipitacions mediterrani, malgrat l¿existència de pulsacions més fredes vers els anys 530 i 700 dC. Les evidències pol·líniques dels usos del sòl indiquen l'extensió d¿activitats ramaderes i agrícoles. Aquesta fase correspon al final del període càlid romà i al període càlid medieval. El canvi de condicions climàtiques es produeix entre els anys 950 i 1100 dC, moment en què els valors mínims de matèria orgànica, pol·len arbori, concentració de diatomees, nitrogen total (TN) i mida del gra indiquen temperatures més baixes i un règim de precipitacions més regular. Aquest període correspon a

Antecedents, psychiatric characteristics and follow-up of adolescents hospitalized for suicide attempt of overwhelming suicidal ideation.

OBJECTIVES: To evaluate the socio-demographic as well as the health and psychiatric profiles of adolescents hospitalised for suicide attempt or overwhelming suicide ideation and to assess repetition of suicide attempt over a period of 18 months. PATIENTS AND METHODS: Between April 2000 and September 2001, all patients aged 16 to 21 years admitted to the University Hospitals of Geneva and Lausanne for suicide attempt or ideation were included in the study. At this time (T0) semi-structured face to face interviews were conducted to identify socio-demographic data, mental health and antecedents regarding suicidal conducts. Current psychiatric status was assessed with the MINI (Mini International Neuropsychiatric Instrument). At T1 and T2, reassessments included psychiatric status (MINI) as well as lifestyles, socio-professional situation and suicidal behaviours. RESULTS: At T0, 269 subjects met the study criteria, among whom 83 subjects (56 girls and 27 boys) left the hospital too quickly to be involved or refused to participate in the study (final sample at T0: 149 girls; 37 boys). The participation rate at T1 and T2 was respectively 66% and 62% of the original sample. The percentage of adolescents meeting the criteria for psychiatric diagnoses (91%) was high: affective disorder (78%); anxiety disorder (64%); substance use disorder (39%); eating disorder (9%); psychotic disorder (11%); antisocial personality (7%) with most subjects (85%) having more than one disorder. Around 90% of the subjects interviewed at T1, and/or T2, had received follow-up care after their hospitalisation, either by a primary care physician or a psychotherapist or both. Two subjects died of violent death and 18% made a further suicide attempt. CONCLUSION: Most adolescents hospitalised for suicidal episodes suffer from psychiatric problems which should be addressed by a careful psychiatric assessment, followed up if needed by a structured after care plan.

Como incrementar a qualidade dos resultados das máquinas de busca: da análise de logs à interação em português

Com o intuito de avaliar a submissão de consultas em língua natural, especificamente em português, a máquinas de busca na Web, e contrastar com as consultas por palavras-chave, realizou-se um experimento com alunos, professores e funcionários de uma universidade brasileira. Particularmente, analisaram-se as consultas para verificar se os usuários expressavam bem seus objetivos em palavras-chave; como expressariam seus objetivos em língua natural, caso esta possibilidade fosse oferecida; se as consultas em língua natural forneciam informações que pudessem facilitar a recuperação de informação. O pedido de colaboração foi enviado a 440 pessoas de um instituto de computação da universidade. Foram obtidas 63 consultas, correspondentes a 42 objetivos. Observou-se que, para o item a, na maioria dos casos (71,43%), as consultas por meio de palavras-chave não trazem todas as informações declaradas importantes no objetivo; para o item b as consultas foram feitas por meio de perguntas (71,87%), afirmações (18,75%) e ordens (9,37%); e, para o item c todas as perguntas diretas deixavam claro o objetivo da consulta já com a primeira palavra da frase, ou com as duas ou três primeiras, com exceção das iniciadas pela palavra "qual".

Physical activity and energy expenditure in rheumatoid arthritis patients and matched controls.

OBJECTIVES: To compare daily energy expenditure between RA patients and matched controls, and to explore the relationship between daily energy expenditure or sedentariness and disease-related scores. METHODS: One hundred and ten patients with RA and 440 age- and sex-matched controls were included in this study. Energy expenditure was assessed using the validated physical activity (PA) frequency questionnaire. Disease-related scores included disease activity (DAS-28), functional status (HAQ), pain visual analogue scale (VAS) and fatigue VAS. Total energy expenditure (TEE) and the amount of energy spent in low- (TEE-low), moderate- (TEE-mod) and high-intensity (TEE-high) PAs were calculated. Sedentariness was defined as expending <10% of TEE in TEE-mod or TEE-high activities. Between-group comparisons were computed using conditional logistic regression. The effect of disease-related scores on TEE was investigated using linear regression. RESULTS: TEE was significantly lower for RA patients compared with controls [2392 kcal/day (95% CI 2295, 2490) and 2494  kcal/day (2446, 2543), respectively, P = 0.003]. A significant difference was found between groups in TEE-mod (P = 0.015), but not TEE-low (P = 0.242) and TEE-high (P = 0.146). All disease-related scores were significantly poorer in sedentary compared with active patients. TEE was inversely associated with age (P < 0.001), DAS-28 (P = 0.032) and fatigue VAS (P = 0.029), but not with HAQ and pain VAS. CONCLUSION: Daily energy expenditure is significantly lower in RA patients compared with matched controls, mainly due to less moderate-intensity PAs performed. Disease activity and fatigue are important contributing factors. These points need to be addressed if promoting PA in RA patients is a health goal. Trial registration.

Acute life-threatening extrinsic allergic alveolitis in a paint controller.

BACKGROUND: Occupational diisocyanate-induced extrinsic allergic alveolitis (EAA) is a rare and probably underestimated diagnosis. Two acute occupational EAA cases have been described in this context, but neither of them concerned hexamethylene diisocyanate (HDI) exposure. AIMS: To investigate the cause of a life-threatening EAA arising at work in a healthy 30-year-old female paint quality controller. METHODS: Occupational medical assessment, workplace evaluation, airborne and biological monitoring and immunodermatological tests. RESULTS: Diagnosis of EAA relied on congruent clinical and radiological information, confirmed occupational HDI exposure and positive IgG antibodies and patch tests. The patient worked in a small laboratory for 7 years, only occasionally using HDI-containing hardeners. While working with HDI for 6 h, she developed breathlessness, rapidly progressing to severe respiratory failure. Workplace HDI airborne exposure values ranged from undetectable levels to 4.25 p.p.b. Biological monitoring of urinary hexamethylene diamine in co-workers ranged from <1.0 to 15.4 μg/g creatinine. Patch tests 8 months later showed delayed skin reaction to HDI at 48 h. Subsequent skin biopsy showed spongiotic dermatitis with infiltration of CD4(+) and CD8(+) T cells. CONCLUSIONS: We believe this is the first reported case of acute life-threatening EAA following exposure to HDI. Low concentrations of airborne HDI and relatively high urinary hexamethylene diamine suggest significant skin absorption of HDI could have significantly contributed to the development of this acute occupational EAA.
