Stratigraphy and palaeoenvironment of Early Jurassic dinosaur-bearing volcaniclastic deposits from Toundoute (Province of Ouarzazate, Haut-Atlas, Morocco)

The Early Jurassic dinosaur site of Toundoute which yielded the basal sauropod Tazoudasaurus naimi is examined in the light of its stratigraphic, sedimentological and palaeoenvironmental context. A thin succession of Early Liassic marine carbonates (probably Hettangian-Sinemurian in age) is continuously overlain by continental beds with dinosaurs. These latter are assumed to be of Middle to Late Liassic age. The continental deposits include a large part of volcanoclastics, different from the Triassic basalts. The Jurassic volcanoclastics originated from an unknown but obviously close eruption centre. The continental sediments (channels and flood plain) were deposited under tropical climate conditions with alternating humid and dry episodes. The bones occur as isolated or partly articulated elements (parts of carcasses). The two bone-beds are related to typical mud-flows. This type of transport protected the bones from erosion, and favoured their burying and fossilization.

Fouilles suisses à Derecik, Büyükorhan, province de Bursa (Turquie). Rapport préliminaire 2007-2008

La découverte en 2001 d'une église et de son pavement sur le site de Derecik près de la ville de Büyükorhan en Turquie a suscité de premières fouilles par les archéologues du Musée archéologique de Bursa, capitale de province, la même année. La présentation des mosaïques en 2006 aux participants d'un colloque organisé par l'Université Uludag de Bursa a permis l'intervention d'une équipe suisse sur les lieux dès 2007. Deux années de fouille et d'observations ont conduit à distinguer plusieurs phases de construction de l'église elle-même et de l'emplacement sur lequel elle est implantée. Un temple de construction légère l'a précédée, vraisemblablement dédié à Zeus, et au moins trois phases de construction la caractérisent, complétées par des aménagements postérieurs. L'occupation des lieux est attestée depuis le IIe siècle ap. J.-C., sinon avant, jusqu'aux invasions arabes du VIIIe siècle ap. J.-C.

High proportion of wrongly identified methicillin-resistant Staphylococcus aureus carriers by use of a rapid commercial PCR assay due to presence of staphylococcal cassette chromosome element lacking the mecA gene.

During a 9-month period, 217 patients were newly diagnosed as methicillin-resistant Staphylococcus aureus (MRSA) carriers by using a commercial rapid PCR-based test (GeneXpert). However, no MRSA was recovered by culturing the second swab in 61 of these patients. Further analyses showed that 28 (12.9%) of the patients harbored S. aureus isolates with a staphylococcal cassette chromosome element lacking the mecA gene and were thus incorrectly determined to be MRSA carriers.

Les délits commis par les employés dans les secteurs commercial et financier : certaines formes de la criminalité économique à la lumière d'une étude de victimisation et de prévention dans les entreprises du canton de Genève

Summary: Victims of crime are not only physical persons. Firms also experience some different forms of victimization either from outsiders or front employees. Crimes committed inside the firm are various: theft, embezzlement, fraud, fraudulent management, money laundering, vandalism etc. Assessed damage could be considerable. But in general, most of the criminological studies relating to victimization have been interested in individuals as victims. In Switzerland, to date, research on firms'victimization is simply rare and traditional research methods such as victimization survey, self-reported delinquency or controlled experiments are not very much utilized in Swiss white-collar crime studies. Thus, in order to improve the situation, we have decided to start a victimization study on white-collar crime committed in firms of the canton of Geneva. To narrow the field of research, our project seeks to apprehend white-collar crime as a series of offences committed by employees inside the firm, by fraud or deceit, aiming at an illegitimate enrichment. The phenomenon of white-collar crime perpetrated has been evaluated by examining the presence of risk factors and prevention strategies. Furthermore, the correlation between the victimization rate and some aspects of vulnerability has also been investigated. Using data collected from the victimization survey carried out in 2005, some of the key research questions are the following: - which are the types of offences committed? - Which types of measure of prevention are the most efficient to prevent such offences ? - Which type of business is more vulnerable? - Which are the risk factors? - Which is the profile of the authors? - Which are the motivations?, etc. Findings show that companies which valorize their employees and pursue a transparent management style suffer a lower victimization rate. Further, the retail sector seems to be more affected than the financial sector and big firms are more vulnerable.

Late Labradorian metamorphism and anorthosite-granitoid intrusion, Cape-Caribou River allochthon, Grenville Province, Labrador - Evidence from U-Pb geochronology

In the Cape Caribou River allochthon (CCRA), metaigneous and gneissic units occur as a shallowly plunging synform in the hanging wall of the Grand Lake thrust system (GLTS), a Grenvillian structure that forms the boundary between the Mealy Mountains and Groswater Bay terranes. The layered rocks of the CCRA are cut by a stockwork of monzonite dykes related to the Dome Mountain suite and by metadiabase-amphibolite dykes that probably form part of the ca. 1380 Ma Mealy swarm. The mafic dykes appear to postdate much of the development of subhorizontal metamorphic layering within the lower parts of the CCRA. The uppermost (least metamorphosed) units of the CCRA, the North West River anorthosite-metagabbro and the Dome Mountain monzonite suite, have been dated at 1625 +/- 6 and 1626 +/- 2 Ma, respectively. An amphibolite unit that concordantly underlies the anorthosite-metagabbro and is intruded discordantly by monzonite dykes has given metamorphic ages of 1660 +/- 3 and 1631 +/- 2 Ma. Granitoid gneisses that form the lowest level of the CCRA have given a migmatization age of 1622 +/- 6 Ma. The effects of Grenvillian metamorphism become apparent in the lower levels of the allochthon where gneisses, amphibolite, and mafic dykes have given new generation zircon ages of 1008 +/- 2, 1012 +/- 3, and 1011 +/- 3 Ma, respectively. A posttectonic pegmatite has also given zircon and monazite ages of 1016(-3)(+7) and 1013 +/- 3 Ma, respectively. Although these results indicate new growth of Grenvillian zircon, this process was generally not accompanied by penetrative deformation or melting. Thus, the formation of gneissic fabrics and the overall layered nature of the lower CCRA are a result primarily of Labradorian (1660-1620 Ma) tectonism and intrusion, and probably reflect early movement on an ancestral GLTS. Grenvillian heating and metamorphism (up to granulite facies) was strongly concentrated towards the base of the CCRA and probably occurred during northwestward thrusting of the allochthon over the Groswater Bay terrane.
