Continuous monitoring of mixed venous oxygen saturation in infants after cardiac surgery
1989
Continuous mixed venous oxygen saturation (SvO2c) was measured in 16 infants immediately after cardiac surgery. A polyurethane 4F, dual channel catheter (Opticath, Modell U440, Oximetrix) with fiberoptic filaments was introduced into the pulmonary artery during cardiothoracic surgery. The catheters were left in place for an average of 67.5 h (range 27 h -125 h) and there were no catheter-related complications. Correlation between continuous in vivo SvO2 values and in vitro values was satisfactory (r = 0.85), whereas a correlation between SvO2c and arterial oxygen saturation (SaO2) was not found (r = 0.07). The sampled arterial lactate values were inversely correlated to the simultaneously m…
Les chiffres : les comprendre pour s'en dépendre
2011
C'est le regard d'une sociologue qualitativiste qui a fait l'objet de cette conférence invitée. D'un forum qui replaçait au centre des débats l'éthique et le vivre-ensemble, mais inscrit dans un atelier sur "les nombres", l'intervention d'un chercheur qualitativiste, aux côtés d'un mathématicien Thierry Duchesne (Université Laval) et de la démographe Chantal Girard (ISQ - Institut de la statistique du Québec), a fait figure de contre-emploi. La communication s'est centrée sur la remise en question de l'universalité du nombre : le nombre, dans son rapport à l'écrit est-il un sociocentrisme ? Cet universalisme supposé peut également être débattu au regard de l'usage historique du nombre (de l…

Building a benchmark through active surveillance of intensive care unit-acquired infections: the Italian network SPIN-UTI.
2010
The Italian Nosocomial Infections Surveillance in Intensive Care Units (ICUs) (SPIN-UTI) project of the Italian Study Group of Hospital Hygiene (GISIO - SItI) was undertaken to ensure standardisation of definitions, data collection and reporting procedures using the Hospital in Europe Link for Infection Control through Surveillance (HELICS)-ICU benchmark. Before starting surveillance, participant ICUs met in order to involve the key stakeholders in the project through participation in planning. Four electronic data forms for web-based data collection were designed. The six-month patient-based prospective survey was undertaken from November 2006 to May 2007, preceded by a one-month surveilla…
The use of differentiated Pedagogy in the Elementary School Classroom and its Psychological Determinants
2010
The purpose of this study is to understand the fundamental reasons enhancing elementary school teachers to accept, or not, the use of differentiated pedagogy in the classroom. A derivative model of Ajzen's planned behaviour theory is tested, upon a sample of 111 Tours-city teachers, with applying a structural equation modeling technique (causal path analysis using maximum likelihood estimates). It combines four psychological determinants of the use of differentiated pedagogy: perception of difficulties, beliefs in norms, behavioural beliefs, and global attitude towards behaviour. This model is adjusted exactly to data. Global attitude has the most important impact on behaviour, perception o…
Archéologie du cheval
2002
Ouvrage de vulgarisation; Les restes d'équidés découverts sur les sites archéologiques constituent la source documentaire la plus cohérente que l'on puisse imaginer pour écrire l'histoire du cheval et de ses rapports avec l'homme, sur une période qui couvre sept millénaires, du Mésolithique aux temps modernes.Cette présentation repose essentiellement sur les découvertes archéologiques réalisées en France, mais certaines approches synthétiques prennent en compte un domaine plus large, celui de l'Europe. De même, si l'accent est mis sur l'apport des ossements découverts en fouille, d'autres sources, iconographiques ou textuelles notamment, sont sollicitées ici et là. Nous n'avons pas les moye…
Analyse de la genèse temporelle des trajectoires scolaires
1989
Analysis of the development of schooling routes in the course of time. - The authors present an empirical analysis of two fundamental questions in the field of knowledge and action : what are the respective parts : 1) of the primary and secondary school ; 2) of educational and institutional phenomena in the explanation of social differences of scolarity ? They conclude with a methodological thinking about the empirical analysis of educational phenomena which needs to take account of time.
Vers des systèmes viticoles économes en pesticides
2022
L’utilisation de produits phytosanitaires (cuivre, soufre et produits de synthèses) est à ce jour le moyen de lutte le plus efficace pour garantir une vendange qualitative et quantitative (Pujol, 2017). Face aux préoccupations sociétales croissantes concernant l’impact des pesticides sur l’environnement et la santé, la viticulture se doit pourtant de réduire sa dépendance aux produits phytosanitaires. Une transition agroécologique est ainsi nécessaire et implique de changer les pratiques afin de parvenir à diminuer l’utilisation des produits phytosanitaires. Le réseau DEPHY-Ferme a été créé en 2010 afin d’initier et stimuler cette transition agroécologique et répondre aux enjeux ambitieux i…
From Buildings' End of Life to Aggregate Recycling under a Circular Economic Perspective: A Comparative Life Cycle Assessment Case Study
2021
The demolition of buildings, apart from being energy intensive and disruptive, inevitably produces construction and demolition waste (C&Dw). Unfortunately, even today, the majority of this waste ends up underexploited and not considered as valuable resources to be re-circulated into a closed/open loop process under the umbrella of circular economy (CE). Considering the amount of virgin aggregates needed in civil engineering applications, C&Dw can act as sustainable catalyst towards the preservation of natural resources and the shift towards a CE. This study completes current research by presenting a life cycle inventory compilation and life cycle assessment case study of two buildin…
Multiscale study of rainfall and vegetation cover in Cameroon : spatial analysis, temporal trends, climatic and anthropogenic factors of NDVI variabi…
2011
Due to its shape and location (2°N-13°N – 8°E-16°E; proximity of the Atlantic Ocean), Cameroon is characterized by a panel of cross-regional climate encountered widely in tropical Africa. Over the region, the decrease rainfall during the second half of the last century has been shown to be associated with stronger recurrence of drier periods, specifically in the core of the rainy season. These conditions have favored the degradation of vegetation cover, driven by socioeconomic and demographic constraints. The substantial impacts on human activities and local society highlight the need to better understand how climate and environmental dynamics do interact locally. The aim of this study is t…
