Staff extremity doses in interventional radiology. Results of the ORAMED measurement campaign

The introduction of interventional radiology (IR) procedures in the 20th century has demonstrated significant advantages over surgery procedures. As a result, their number is continuously rising in diagnostic, as well as, in therapy field and is connected with progress in highly sophisticated equipment used for these purposes. Nowadays, in the European countries more than 400 fluoroscopically guided IR procedures were identified with a 10-12% increase in the number of IR examinations every year (UNSCEAR, 2010). Depending on the complexity of the different types of the interventions large differences in the radiation doses of the staff are observed.The staff that carries out IR procedures is likely to receive relatively high radiation doses, because IR procedures require the operator to remain close to the patient and close to the primary radiation beam. In spite of the fact that the operator is shielded by protective apron, the hands, eyes and legs remain practically unshielded. For this reason, one of the aims of the ORAMED project was to provide a set of standardized data on extremity doses for the personnel that are involved in IR procedures and to optimize their protection by evaluating the various factors that affect the doses. In the framework of work package 1 of the ORAMED project the impact of protective equipment, tube configuration and access routes were analyzed for the selected IR procedures. The position of maximum dose measured is also investigated. The results of the extremity doses in IR workplaces are presented in this study together with the influence of the above mentioned parameters on the doses.

Trends in the association between height and socioeconomic indicators in France, 1970-2003

Average physical stature has increased dramatically during the 20th century in many populations across the world with few exceptions. It remains unclear if social inequalities in height persist despite improvements in living standards in the welfare economies of Western Europe. We examined trends in the association between height and socioeconomic indicators in adults over three decades in France. The data were drawn from the French Decennial Health Surveys: a multistage, stratified, random survey of households, representative of the population, conducted in 1970, 1980, 1991, and 2003. We categorised age into 10-year bands, 25-34, 35-44, 45-54 and 55-64 years. Education and income were the two socioeconomic measures used. The slope index of inequality (SII) was used as a summary index of absolute social inequalities in height. The results show that average height increased over this period; men and women aged 25-34 years were 171.9 and 161.2 cm tall in 1970 and 177.0 and 164.0 cm in 2003, respectively. However, education-related inequalities in height remained unchanged over this period and in men were 4.48 cm (1970), 4.71 cm (1980), 5.58 cm (1991) and 4.69 cm (2003), the corresponding figures in women were 2.41, 2.37, 3.14 and 2.96 cm. Income-related inequalities in height were smaller and much attenuated after adjustment for education. These results suggest that in France, social inequalities in adult height in absolute terms have remained unchanged across the three decades under examination.

Autism in schizophrenia revisited.

The concept of autism is reviewed in its historical evolution. It is suggested that the Bleulerian insistence on the withdrawal component in autism contributed to the decline of its use in adult psychiatry. Phenomenology offers another approach to grasping the nature of autism as a relational (subject-outer world) phenomenon. European phenomenological psychiatry in the field of schizophrenia is introduced and its attempts to reveal the essence of autism are presented. Autism is here considered as a "loss of vital contact with reality" (Minkowski), "inconsistency of natural experience" (Binswanger), or "the global crisis of common sense" (Blankenburg). It is proposed that autism represents dysfunctional perceptual/expressive attunement to the outer world. The usefulness of this concept is briefly examined in relation to the diagnosis and etiopathogenesis of schizophrenia.

On the Definition of Public Goods. Assessing Richard A. Musgrave's contribution

This paper provides an explanation of the emergence of the standard textbook definition of public goods in the middle of the 20th century. It focuses on Richard Musgrave's contribution in defining public goods as non-rival and non-excludable - from 1939 to 1969. Although Samuelson's mathematical definition is generally used in models of public goods, the qualitative understanding of the specificity of pure public goods owes more to Musgrave's emphasis on the impossibility of exclusion. This paper also highlights the importance of the size of the group to which benefits of a public good accrue. This analysis allow for a reassessment of the Summary table of goods which first appeared in Musgrave and Musgrave (1973) textbook.

There and back again? Combining habitat suitability modelling and connectivity analyses to assess a potential return of the otter to Switzerland

After a steady decline in the early 20th century, several terrestrial carnivore species have recently recovered in Western Europe, either through reintroductions or natural recolonization. Because of the large space requirements of these species and potential conflicts with human activities, ensuring their recovery requires the implementation of conservation and management measures that address the environmental, landscape and social dimensions of the problem. Few examples exist of such integrated management. Taking the case of the otter (Lutra lutra) in Switzerland, we propose a multi-step approach that allows to (1) identify areas with potentially suitable habitat, (2) evaluate their connectivity, (3) verify the potentiality of the species recolonization from populations in neighbouring countries. We showed that even though suitable habitat is available for the species and the level of structural connectivity within Switzerland is satisfactory, the level of connectivity with neighbouring populations is crucial to prioritize strategies that favour the species recovery in the field. This research is the first example integrating habitat suitability and connectivity assessment at different scales with other factors in a multi-step assessment for species recovery.

Contribution à la cartographie géomorphologique de la dynamique sédimentaire des petits bassins versants torrentiels

Les laves torrentielles sont l'un des vecteurs majeurs de sédiments en milieu montagneux. Leur comportement hydrogéomorphologique est contrôlé par des facteurs géologique, géomorphologique, topographique, hydrologique, climatique et anthropique. Si, en Europe, la recherche s'est plus focalisée sur les aspects hydrologiques que géomorphologiques de ces phénomènes, l'identification des volumes de sédiments potentiellement mobilisables au sein de petits systèmes torrentiels et des processus responsables de leur transfert est d'une importance très grande en termes d'aménagement du territoire et de gestion des dangers naturels. De plus, une corrélation entre des événements pluviométriques et l'occurrence de laves torrentielles n'est pas toujours établie et de nombreux événements torrentiels semblent se déclencher lorsqu'un seuil géomorphologique intrinsèque (degré de remplissage du chenal) au cours d'eau est atteint.Une méthodologie pragmatique a été développée pour cartographier les stocks sédimentaires constituant une source de matériaux pour les laves torrentielles, comme outil préliminaire à la quantification des volumes transportés par ces phénomènes. La méthode s'appuie sur des données dérivées directement d'analyses en environnement SIG réalisées sur des modèles numériques d'altitude de haute précision, de mesures de terrain et d'interprétation de photographies aériennes. La méthode a été conçue pour évaluer la dynamique des transferts sédimentaires, en prenant en compte le rôle des différents réservoirs sédimentaires, par l'application du concept de cascade sédimentaire sous un angle cartographique.Les processus de transferts sédimentaires ont été étudiés dans deux bassins versants des Alpes suisses (torrent du Bruchi, à Blatten beiNaters et torrent du Meretschibach, à Agarn). La cartographie géomorphologique a été couplée avec des mesures complémentaires permettant d'estimer les flux sédimentaires et les taux d'érosion (traçages de peinture, piquets de dénudation et utilisation du LiDAR terrestre). La méthode proposée se révèle innovatrice en comparaison avec la plupart des systèmes de légendes géomorphologiques existants, qui ne sont souvent pas adaptés pour cartographier de manière satisfaisante les systèmes géomorphologiques complexes et actifs que sont les bassins torrentiels. L'intérêt de cette méthode est qu'elle permet l'établissement d'une cascade sédimentaire, mais uniquement pour des systèmes où l'occurrence d'une lave torrentielle est contrôlé par le degré de remplissage en matériaux du chenal. Par ailleurs, le produit cartographique ne peut être directement utilisé pour la création de cartes de dangers - axées sur les zones de dépôt - mais revêt un intérêt pour la mise en place de mesures de correction et pour l'installation de systèmes de monitoring ou d'alerte.La deuxième partie de ce travail de recherche est consacrée à la cartographie géomorphologique. Une analyse a porté sur un échantillon de 146 cartes ou systèmes de légende datant des années 1950 à 2009 et réalisés dans plus de 40 pays. Cette analyse a permis de mettre en évidence la diversité des applications et des techniques d'élaboration des cartes géomorphologiques. - Debris flows are one of the most important vectors of sediment transfer in mountainous areas. Their hydro-geomorphological behaviour is conditioned by geological, geomorphological, topographical, hydrological, climatic and anthropic factors. European research in torrential systems has focused more on hydrological processes than on geomorphological processes acting as debris flow triggers. Nevertheless, the identification of sediment volumes that have the potential to be mobilised in small torrential systems, as well as the recognition of processes responsible for their mobilisation and transfer within the torrential system, are important in terms of land-use planning and natural hazard management. Moreover, a correlation between rainfall and debris flow occurrence is not always established and a number of debris flows seems to occur when a poorly understood geomorphological threshold is reached.A pragmatic methodology has been developed for mapping sediment storages that may constitute source zone of bed load transport and debris flows as a preliminary tool before quantifying their volumes. It is based on data directly derived from GIS analysis using high resolution DEM's, field measurements and aerial photograph interpretations. It has been conceived to estimate sediment transfer dynamics, taking into account the role of different sediment stores in the torrential system applying the concept of "sediment cascade" in a cartographic point of view.Sediment transfer processes were investigated in two small catchments in the Swiss Alps (Bruchi torrent, Blatten bei Naters and Meretschibach torrent, Agarn). Thorough field geomorphological mapping coupled with complementary measurements were conducted to estimate sediment fluxes and denudation rates, using various methods (reference coloured lines, wooden markers and terrestrial LiDAR). The proposed geomorphological mapping methodology is quite innovative in comparison with most legend systems that are not adequate for mapping active and complex geomorphological systems such as debris flow catchments. The interest of this mapping method is that it allows the concept of sediment cascade to be spatially implemented but only for supply-limited systems. The map cannot be used directly for the creation of hazard maps, focused on the deposition areas, but for the design of correction measures and the implementation of monitoring and warning systems.The second part of this work focuses on geomorphological mapping. An analysis of a sample of 146 (extracts of) maps or legend systems dating from the middle of the 20th century to 2009 - realised in more than 40 different countries - was carried out. Even if this study is not exhaustive, it shows a clear renewed interest for the discipline worldwide. It highlights the diversity of applications, techniques (scale, colours and symbology) used for their conception.

Berguer, Rochedieu: Flournoy's legacy in the Genevan school of the psychology of religion

In 1891 Théodore Flournoy (1854-1920) became the first Professor of Psychology to be appointed at the University of Geneva, and his teaching regularly included references to religion. His successor, Georges Berguer, who taught psychology of religion, began as privat-docent in 1910 and received a full professorship in Religious Psychology and the History of Religion in 1928. French-speaking Switzerland is one of the rare places in the world where psychology of religion has been taught continuously since the very beginning of the 20th century. The aim of this article is to shed light on this tradition and especially on Georges Berguer (retired in 1944) and Edmond Rochedieu (retired in 1965) who succeeded Flournoy. This historical enterprise concludes with some reflections on the role of the psychology of religion at the intersection of psychology and the study of religions.

Dietary fat, lipogenesis and energy balance.

Today, there are still uncertainties about the role of exogenous fat on body fat regulation. Early models of energy utilization (for example, Kleiber's, early 20th century) failed to take into account the nature of substrate oxidized in the control of food intake, whereas more recent models (e.g., Flatt's model, end of 20th century) did. Excess body fat storage is ultimately a problem of chronic positive energy balance mediated by a poor control of energy intake or/and a blunted total energy expenditure. Excess fat storage can stem from exogenous fat and to a more limited extent by nonfat substrates precursors transformed into body fat, mostly from carbohydrates, a process known as de novo lipogenesis. When considered over periods of weeks, months or years, total fat balance is closely related to energy balance. Over periods of days, the net change in fat balance is quantitatively limited as compared to the size of endogenous fat storage. The issues discussed in this article primarily include the stimulation of de novo lipogenesis after acute or prolonged CHO overfeeding and whether de novo lipogenesis is a risk factor for obesity development.
