La force motrice hydraulique au service du développement économique helvétique : L'exemple du réseau d'eau sous pression à Lausanne 1868-1914

The success story of hydroelectricity long influenced and dominated Swiss scholarly literature devoted to the history of technology. This means of conducting power, which emerged at the end of the 19th century and is still dominating today, has attracted much more attention than technologies that have been shadowed by its success. In spite of their important contribution to Swiss economic development, the distribution networks of pressurized water have been neglected by scholars. This article contributes to close this historiographic gap by analyzing the introduction of pressurized water distribution in 1876 in Lausanne, in the context of the building of the first Swiss cable funicular between Lausanne and Ouchy. This article shows how pressurized water distribution transformed socio-economic practices in the urban areas in which it was adopted. Indeed, this innovation, which allowed the use of distant hydraulic resources, enabled the rationalization of industrial and artisanal production as well as improved the density of the urban industrial base. By facilitating the introduction of electric lighting, pressurized water networks played a key role in the early development, and further successes, of the Swiss hydroelectric industry.

Training effects with the observer-rated cognitive errors and the coping action patterns scales

The use of observer-rated scales requires that raters be trained until they have become reliable in using the scales. However, few studies properly report how training in using a given rating scale is conducted or indeed how it should be conducted. This study examined progress in interrater reliability over 6 months of training with two observer-rated scales, the Cognitive Errors Rating Scale and the Coping Action Patterns Rating Scale. The evolution of the intraclass correlation coefficients was modeled using hierarchical linear modeling. Results showed an overall training effect as well as effects of the basic training phase and of the rater calibration phase, the latter being smaller than the former. The results are discussed in terms of implications for rater training in psychotherapy research.

Non-remboursement de la fécondation in vitro : il est temps de changer d'avis

La fécondation in vitro (FIV) n'est pas remboursée. Le Tribunal fédéral le répète inlassablement depuis bientôt 30 ans. Néanmoins, les assurées ne baissent pas les bras et périodiquement resoumettent la question, espérant que de nouvelles données scientifiques sauront infléchir la Haute Cour. En vain. Le tribunal l'a redit en octobre 2012:1 cette prestation n'est pas à charge des caisses.2 L'ordonnance sur les prestations de l'assurance-maladie (OPAS3) le prévoit explicitement, et il n'y a simplement pas lieu d'examiner une disposition d'une ordonnance du Département fédéral de l'intérieur (DFI). Le raisonnement est toutefois un peu court. Premièrement, le refus du Tribunal fédéral d'examiner si l'ordonnance respecte le cadre de la délégation législative ne convainc pas. Deuxièmement, la FIV remplit les critères imposés à la prise en charge tels que décidés par le législateur dans la loi sur l'assurance-maladie (LAMal4). Enfin, les assurés qui décident de recourir contre un refus de remboursement sont privés des garanties minimales de procédure que leur garantit pourtant la Convention européenne des droits de l'homme. La présente contribution commence par une brève description de la FIV. Elle expose ensuite la législation applicable (partie 2) et la jurisprudence fédérale qui en découle (partie 3). La partie suivante critique la position du Tribunal fédéral au regard des principes énoncés dans la législation. Une comparaison avec l'insémination intra-utérine (IIU), pour laquelle le Tribunal fédéral a admis le remboursement, met en lumière les incohérences de la jurisprudence. La compatibilité de la jurisprudence fédérale avec l'art. 6 de la Convention européenne sur les droits de l'homme est évaluée. La conclusion plaide pour une réforme partielle du système procédural gouvernant la prise en charge des prestations de soins, mais aussi des techniques médicales alternatives.

Comparative winter thermoregulation and body temperature in three sympatric Apodemus species (A-alpicola, A-flavicollis, and A-sylvaticus)

When living in sympatry with Apodemus sylvaticus and A. flavicollis, A. alpicola dominates numerically at higher altitudes. A more efficient winter thermal isolation or a higher winter thermogenic capacity procuring a physiological advantage could explain at least part of this domination. We therefore measured body temperature (Tb), oxygen consumption (VO2), wet minimal thermal conductance (C) and non shivering thermogenesis (NST) at different ambient temperatures (Ta) on winter acclimated mice of the three species, and this for the first time in A. alpicola. NST was high and C low in the three species. No significant difference could be noticed either in Tb between 5 and -10 degrees C, in VO2 measurements at a Ta of -10 degrees C or in C. The NST measurements represent, respectively, 135.2% for A. sylvaticus, 142.8% for A. flavicollis and 140.5% for A. alpicola of the expected values, the values for A. sylvaticus being significantly lower than for the other two species. The basal metabolic rates (BMR) represent 169.4% for A. sylvaticus, 161.6% for A. flavicollis and 138.3% for A. alpicola of the expected values. Having removed the effect of body weight, the BMR value was significantly lower in A. alpicola than in A. flavicollis, but no difference could be noticed between A. sylvaticus and the other two species. In conclusion, the three species of mice have very similar acclimated thermoregulatory characteristics, well adapted to cold ambient conditions. One discriminating and advantageous factor could be the lower basal metabolic rate measured in A. alpicola compared to the other two species.

Gastrointestinal complications of post-diarrheal hemolytic uremic syndrome.

PURPOSE: Whereas gastrointestinal symptoms such as vomiting, diarrhea and abdominal pain are common in children suffering from the so-called post-diarrheal form (D+) of hemolytic uremic syndrome (HUS), more serious gastrointestinal complications are rare. We tried to define factors predictive of the severity of gastrointestinal complications post D+ HUS. METHODS: We reviewed the files of all children admitted to our hospital for D+ HUS between 1988 and 2000. We retained those cases with gastrointestinal complications and analyzed the consequences of these complications on the evolution of the children's conditions. RESULTS: Sixty-five children with D+ HUS were admitted to our hospital during this period. Sixteen children developed gastrointestinal complications involving one or more digestive organs: necrosis of the colon or ileum, hemorrhagic colitis, pancreatitis, transient diabetes, hepatic cytolysis and cholestasis, peritonitis and prolapse of the rectum. One child died. CONCLUSION: Gastrointestinal complications of D+ HUS are rare, but they can be lethal, and early surgery may sometimes prove necessary. However, we were not able to demonstrate a correlation between the severity of the gastrointestinal manifestations and the clinical or biological signs accompanying D+ HUS.
