Integrated Ladinian bio-chronostratigraphy and geochrononology of Monte San Giorgio (Southern Alps, Switzerland)

New biostratigraphic data significantly improve the age assignment of the Ladinian succession of Monte San Giorgio (UNESCO World Heritage List site, Southern Alps, Switzerland), whose world-famous fossil marine vertebrate faunas are now dated to the substage and zone levels. High-resolution single-zircon U-Pb dating was performed using ID-TIMS and chemical abrasion (CA) pre-treatment technique on volcanic ash layers intercalated in the biostratigraphically-defined intervals of the Meride Limestone. It yielded ages of 241.07 +/- 0.13 Ma (Cava superiore beds, P. gredleri Zone), 240.63 +/- 0.13 Ma (Cassina beds, P gredleri/P. archelaus transition Zone) and 239.51 +/- 0.15 Ma (Lower Kalkschieferzone, P. archelaus Zone). Our results suggest that the time interval including the vertebrate-bearing Middle Triassic section spans around 4 Myr and is thus significantly shorter than so far assumed. The San Giorgio Dolomite and the Meride Limestone correlate with intervals of the Buchenstein Formation and the Wengen Formation in the reference section at Bagolino, where the Global boundary Stratotype Section and Point (GSSP) for the base of the Ladinian was defined. The new radio-isotopic ages of the Meride Limestone are up to 2 Myr older than those published for the biostratigraphically-equivalent intervals at Bagolino but they are consistent with the recent re-dating of the underlying Besano Formation, also performed using the CA technique. Average sedimentation rates at Monte San Giorgio are by more than an order of magnitude higher compared to those assumed for the Buchenstein Formation, which formed under sediment-starved pelagic conditions, and reflect prevailing high subsidence and high carbonate mud supply from the adjoining Salvatore/Esino platforms. Finally, the high-resolution U-Pb ages allow a correlation of the vertebrate faunas of the Cava superiore/Cava inferiore beds with the marine vertebrate record of the Prosanto Formation (Upper Austroalpine), so far precluded by the poor biostratigraphic control of the latter.

First consumption ever of multiple substances: applying an expert-based taxonomy to a Swiss national sample of adolescents.

The use of multiple legal and illegal substances by adolescents is a growing concern in all countries, but since no consensus about a taxonomy did emerge yet, it is difficult to understand the different patterns of consumption and to implement tailored prevention and treatment programs directed towards specific subgroups of the adolescent population. Using data from a Swiss survey on adolescent health, we analyzed the age at which ten legal and illegal substances were consumed for the first time ever by applying a method combining the strength of both automatic clustering and use of substance experts. Results were then compared to 30 socio-economic factors to establish the usefulness of and to validate our taxonomy. We also analyzed the succession of substance first use for each group. The final taxonomy consists of eight groups ranging from non-consumers to heavy drug addicts. All but four socio-economic factors were significantly associated with the taxonomy, the strongest associations being observed with health, behavior, and sexuality factors. Numerous factors influence adolescents in their decision to first try substances or to use them on a regular basis, and no factor alone can be considered as an absolute marker of problematic behavior regarding substance use. Different processes of experimentation with substances are associated with different behaviors, therefore focusing on only one substance or only one factor is not efficient. Prevention and treatment programs can then be tailored to address specific issues related to different youth subgroups.

Una visió de la Guerra de Successió des de l'exili: el 'Teatro de desdichas' (Milà, 1716)

El 1716 es publicà a Milà un text que fa una àmplia justificació històrica i política de la causa de Carles III d'Àustria a la Guerra de Successió d'Espanya (1702-1715). L'obra, de dimensions considerables (72 pàgines), va ser redactada per un eclesiàstic castellà que participà a la defensa de Barcelona durant el darrer setge i que va ser desterrat a Itàlia per les noves autoritats borbòniques. L'article analitza algunes de les idees centrals del text, com ara: l'oposició a la tirania borbònica i la defensa d'una monarquia moderada; la identificació de l'entronització de Felip V com el trencament de l'equilibri europeu i el punt culminant de la decadència d'Espanya; la denúncia de la traïció dels aliats; la vindicació de l'austriacisme castellà i la crítica al borbonisme d'alguns sectors catalans; i la descripció de la repressió i de l'exili.

Improving the Understanding and the Reliability of the Concept of "Sufficiency" in Friction Ridge Examination

The National Academies has stressed the need to develop quantifiable measures for methods that are currently qualitative in nature, such as the examination of fingerprints. Current protocols and procedures to perform these examinations rely heavily on a succession of subjective decisions, from the initial acceptance of evidence for probative value to the final assessment of forensic results. This project studied the concept of sufficiency associated with the decisions made by latent print examiners at the end of the various phases of the examination process. During this 2-year effort, a web‐based interface was designed to capture the observations of 146 latent print examiners and trainees on 15 pairs of latent/control prints. Two main findings resulted from the study: The concept of sufficiency is driven mainly by the number and spatial relationships between the minutiae observed on the latent and control prints. Data indicate that demographics (training, certification, years of experience) or non‐minutiae based features (such as level 3 features) do not play a major role in examiners' decisions; Significant variability was observed between detecting and interpreting friction ridge features and at all levels of details, as well as for factors that have the potential to influence the examination process, such as degradation, distortion, or influence of the background and the development technique.

Le droit européen des successions: commentaire du Règlement n° 650/2012 du 4 juillet 2012

De nombreuses successions présentent un élément international : le défunt possédait un ou plusieurs biens dans un autre État ou un héritier ou légataire réside dans un autre État ou encore un créancier réside dans un autre État. Dans toutes ces situations, il est essentiel, pour anticiper sur l'ouverture d'une succession et pour liquider une succession déjà ouverte, de déterminer la juridiction compétente et les règles applicables. Le nouveau droit international privé européen des successions qui entrera en vigueur en 2015, prévoit des règles permettant de répondre à ces questions. Fruit de négociations qui se sont étendues sur plusieurs années, le Règlement offre des solutions nouvelles qui modifieront en substance les habitudes prises par les praticiens. Cet ouvrage offre un commentaire de l'ensemble des dispositions du Règlement qui est appelé devenir le droit commun des successions internationales dans les États membres de l'Union européenne. Chaque disposition fait l'objet d'explications qui permettront au lecteur d'apercevoir la portée du texte et les questions qu'il soulève. Ce commentaire constituera un outil indispensable pour tout praticien du droit qui s'intéresse aux successions, qu'il soit appelé à travailler dans une perspective de planification ou pour liquider une succession ouverte. L'ouvrage intéressera les magistrats, les notaires, les fiscalistes et les avocats spécialisés en planification successorale, droit patrimonial de la famille et en droit de la famille en général.

On the Upper Ordovician unconformity in the Pyrenees: New evidence from the La Cerdanya area

In recent years, contradictory reports about whether or not an unconformity exists at the base of the Upper Ordovician succession of the Pyrenees have been made. In the Cerdanya area (Central Pyrenees), good outcrop evidence for this unconformity is displayed at the base of the Rabassa conglomerates. In this area, the Upper Ordovician rocks overlie a tilted Cambro-Ordovician sequence, displaying an angular unconformity and indicating a break in the stratigraphic series. Moreover, the existence of such an unconformity is supported by the distribution of Variscan minor structures, suggesting that the Cambro-Ordovician and the Upper Ordovician strata initially had different orientations before the main Variscan folding.

Volcanic stratigraphy of Hannah Point, Livingston Island, South Shetland Islands, Antarctica

The Upper Cretaceous volcanic succession of Hannah Point is the best exposure of the Antarctic Peninsula Volcanic Group on L ivingston Island. The aim of the present paper is to contribute to the characterisation of the stratigr a p hy and petrogr a p hy of this little studied succession, and briefly discuss some aspects of the eru p t ive style of its volcanism. The succession is about 470 m thick and is here subdivided into five lithostratigraphic units (A to E from base to top). Unit A, approximately 120 m thick, is mainly composed of polymict clast-supported volcaniclastic breccias and also includes a dacitic lava laye r. Interstratified in the breccias of this unit, there is a thin laminated devitrified layer which shows some degree of welding. Unit B, approx imately 70 m thick, is almost entirely composed of volcaniclastic breccias, and includes a volcaniclastic conglomerate laye r. Breccias in this unit can be subdivided into two distinct types; polymict clast-supported breccias, and monomict matrix-supported breccias rich in juvenile components and displaying incipient welding. Unit C, about 65 m thick, is mainly composed of basaltic lavas, which are interlayered with minor vo lcaniclastic breccias. Unit D, approximately 65 m thick, is lithologically similar to unit B, composed of an alternation of polymict clasts upported breccias and matrix-supported breccias, and includes a volcaniclastic conglomerate laye r. Unit E, about 150 m thick, is mainly formed of thick andesitic lava layers. Minor basaltic dykes and a few normal faults cut the succession, and the contact betwe e n units A and B can be interpreted both as an unconformity or a fault. The matrix-supported breccias included in the succession of Hannah Point have high contents of juvenile components and incipient welding, which suggest that part of the succession is the result of pyroclastic fragmentation and emplacement from pyroclastic flows. In contrast, the polymict clast-supported breccias suggest reworking of previous deposits and deposition from cool mass flows. The lavas indicate eff u s ive volcanic eruptions, and the absence of features indicative of subaqueous volcanism suggests that at least these portions of the succession were emplaced in a subaerial environment .

Coastal salina evaporites of the Triassic-Liassic boundary in the Iberian Peninsula: the Alacón borehole

The evaporite unit (the Lécera Formation), which was formed at the Triassic¿Liassic boundary in the Aragonian Branch of the Iberian Chain, was studied at the 01 Alacón borehole (Alacón village, Teruel province), where it is mainly constituted by a thick (>e and reflect deeper water settings, whereas in the upper part they correspond to shallower water settings. The evaporite sedimentation mainly occurred in a subsiding coastal basin of the salina or lagoon type. In this setting, the subaqueous precipitation of the carbonate and gypsum lithofacies was followed, in each cycle, by the interstitial growth of anhydrite in exposed conditions. As a whole, the evaporite succession reflects an infilling process. The conversion into anhydrite of the selenitic gypsum -probably also of the rest of depositional gypsum lithofaciesstarted under synsedimentary conditions and followed during shallow to moderate burial diagenesis.

Climate and vegetation history of western Portugal inferred from Albian near-shore deposits (Gale Formation, Lusitanian Basin)

The late Early Cretaceous greenhouse climate has been studied intensively based on proxy data derived essentially from open marine archives. In contrast, information on continental climatic conditions and on the accompanying response of vegetation is relatively scarce, most notably owing to the stratigraphic uncertainties associated with many Lower Cretaceous terrestrial deposits. Here, we present a palynological record from Albian near-shore deposits of the Lusitanian Basin of W Portugal, which have been independently dated using Sr-isotope signals derived from low-Mg oyster shell calcite. Sr-87/Sr-86 values fluctuate between 0.707373 +/- 0.00002 and 0.707456 +/- 0.00003; absolute values and the overall stratigraphic trend match well with the global open marine seawater signature during Albian times. Based on the new Sr-isotope data, existing biostratigraphic assignments of the succession are corroborated and partly revised. Spore-pollen data provide information on the vegetation community structure and are flanked by sedimentological and clay mineralogical data used to infer the overall climatic conditions prevailing on the adjacent continent. Variations in the distribution of climate-sensitive pollen and spores indicate distinct changes in moisture availability across the studied succession with a pronounced increase in hygrophilous spores in late Early Albian times. Comparison with time-equivalent palynofloras from the Algarve Basin of southern Portugal shows pronounced differences in the xerophyte/hygrophyte ratio, interpreted to reflect the effect of a broad arid climate belt covering southern and southeastern Iberia during Early Albian times.

Structure and kinematics of the Jungfrau syncline, Faflertal (Valais, Alps), and its regional significance

The formation and structural evolution of the jungrau syncline is described, based on excellent outcrops occurring in the lotschental, in the central alps of switzerland. the quality of the outcrops allows us to demonstrate that the external massifs of the swiss alps have developed due to internal folding. The jungfrau suncline, which separates the autochtonous gastern dome from the aar massif basement gneiss folds, is composed of slivers of basement rocks with their mesozoic sedimentary cover. in the inner faflertal, a side valley of the lotschental, the 200 m thick syncline cp, roses fpir imots, the gastern massif with a reduced mesozoic sedimentary cover in a normal stratigraphic succession, two units of overturned basement rocks with their mesozoic sedimentary cover, and the overturned lower limn of the tschingelhorn gneiss fold of the aar massif with lenses of its sedimentary cover. stratigraphy shows that the lower units, related to the gastern massis, are condensed and that the upper units, deposited farther away from a gastern paleo-high, form a more complete sequence, linked to the doldenhorn meso-cneozoic basin fill. the integration of these local observations with published regional data leads to the following model. on the northern margin of the doldenhorn hbasin, at the northern fringe of the alpine tethuys, the pre-triassic crystalline basement and its mesozoic sedimentary cover were folded by ductile deformation at temperatures above 300 degrees C and in the presence of high fluid pressures, as the helveti c and penninic nappes were overthrusted towards the northwest during the main alpine deformation phase, the visosity contrast between the basement gneisses and the sediments caused the formation of large basement anticlines and tight sedimentary sunclines (mullion-type structures). The edges of basement blocks bounded buy pre-cursor se-dipping normal faults at the northwestern border of the doldenhorn basin were deformed bu simple shear, creating overturned slices of crystalline rocks with their sedimentary cover in what now forms the hungfrau syncline. the localisation of ductile deformation in the vicinity of pre-existing se-dipping faults is thought to have been helped by the circulation of fluids along the faults; these fluids would have been released from the mesozoic sediments by metamorphic dehydration reactions accompanied by creep and dynamic recrystallisation of quartz at temperatures above 300 degrees C. Quantification of the deformation suggests an strain ellipsoid with a ratio (1 + e(1)/+ e(3)) of approximately 1000. The jungfrau suncline was deformed bu more brittle nw-directed shear creating well-developed shear band cleavages at a late stage, after cooling by uplift and erosion. It is suggested that the external massifs of the apls are basement gneiss folds created at temperatures of 300 degrees C by detachment through ductile deformation of the upper crust of the european plate as it was underthrusted below the adriatic plate.

Evidence for middle Cretaceous accretion at Santa Elena Peninsula (Santa Rosa Accretionary Complex), Costa Rica

An oceanic assemblage of alkaline basalts, radiolarites and polymictic breccias forms the tectonic substratum of the Santa Elena Nappe, which is constituted by extensive outcrops of ultramafic and mafic rocks of the Santa Elena Peninsula (NW Costa Rica). The undulating basal contact of this nappe defines several half-windows along the south shores of the Santa Elena Peninsula. Lithologically it is constituted by vesicular pillowed and massive alkaline basaltic flows, alkaline sills, ribbon-bedded and knobby radiolarites, muddy tuffaceous and detrital turbidites, debris flows and polymictic breccias and megabreccias. Sediments and basalt flows show predominant subvertical dips and occur in packages separated by roughly bed-parallel thrust planes. Individual packages reveal a coherent internal stratigraphy that records younging to the east in all packages and shows rapid coarsening upwards of the detrital facies. Alkaline basalt flows, pillow breccias and sills within radiolarite successions are genetically related to a mid-Cretaceous submarine seamount. Detrital sedimentary facies range form distal turbidites to proximal debris flows and culminate in megabreccias related to collapse and mass wasting in an accretionary prism. According to radiolarian dating, bedded radiolarites and soft-sediment- deformed clasts in the megabreccias formed in a short, late Aptian to Cenomanian time interval. Middle Jurassic to Lower Cretaceous radiolarian ages are found in clasts and blocks reworked from an older oceanic basement. We conclude that the oceanic assemblage beneath the Santa Elena Nappe does not represent a continuous stratigraphic succession. It is a pile of individual thrust sheets constituting an accretionary sequence, where intrusion and extrusion of alkaline basalts, sedimentation of radiolarites, turbidites and trench fill chaotic sediments occurred during the Aptian-Cenomanian. These thrust sheets formed shortly before the off-scraping and accretion of the complex. Here we define the Santa Rosa Accretionary Complex and propose a new hypothesis not considered in former interpretations. This hypothesis would be the basis for further research.

Paleozoic stratigraphy of the Central and Northern part of the Catalonian Coastal Ranges (NE Spain)

The Paleozoic stratigraphic succession in the Catalonian Coastal Ranges spans the interval from Cambrian(?) to Carboniferous, with only one break, separating the pre-Carboniferous part of the sequence from the Carboniferous. The oldest rocks exposed form a sequence of schists, fine grained sandstones, gneisses (laminar pre-Hercynian intrusions), marbles, orto- and para-amphibolites and calcsilicate rocks. comparison with other localities iuggests an Early Cambrian age (or perhaps in part older). Upwards the sequence becomes more monotonous andconsists only of schists (or slates where themetamorphic grade is lower) and thin fine-grained sandstone layers (Cambrian-Ordovician). Still higher in the sequence, an altemation of greywackes and slates is found, with interlayered mud-supported conglomerates at its lower part and acid volcanic rocks which occur throughout the whole sequence. This part of the sequence has provided the oldest faunas known in the Catalonian Coastal Ranges, which indicate the Caradoc. Finally, in its uppermost part, the Ordovician sequence contains some thin limestone layers that contain Ashgill faunas. The Silurian, from Llandovery to Lower Ludlow, consists of black graptolitic shales with dolerite sills, whilst the upper Ludlow, Pridolian and Devonian consist of nodular limestones and marls withpelagic and hemipelagic faunas. The youngest Devonian faunas found correspond in general to the Emsian. The existence of a gap at this point of the sequence suggests the possibility that part of the Devonian could have been eroded. The Carboniferous is characterized by a thick culm sequence (Visean to Westphalian?), resting on thin chert and limestone layers (Tournaisian and Visean). A comparison with neighbouring areas shows a similarity regarding succession and facies with other Paleozoic massifs around the Western Mediterranean.

Una reflexión sobre la impronta romana del 'beneficio de separación de patrimonios' en el Código Civil catalán

The roman institution of the separatio bonorum is a pretorian remedy that relies on the principle of equity, created as to protect the deceased creditors and/or legatees. It provides them a"benefit" in the case of selling the goods of the heir-deubtor, enabling them to separate and reserve for themselves that whole patrimonium, as to avoid that by the act of selling, the heirs creditors could go to it; and like this they maintain intact their guarantee, which relies on the whole goods and assets left by the deceased. The separation of patrimonies implied the existence of 2 different groups of goods: that of the heirs" and that one of the deceased, which are not the same in legal terms, in spite of having a common owner at this point, the heir. This institution was regulated in the 6th title of the 42nd book of the Digesto, and in the 72th title, 7th book of the Justinean Code, and its interest is really high due to its material complexity and its procedure. The aim of this work is to analyze the institution of the separatio bonorum in Roman Law, and its importance in the same figure, actually regulated in the 4th book of the Catalan civil code.

Association atypique d'une démence sémantique, d'un syndrome cortico-basal et d'une tauopathie 4R = [Atypical association of semantic dementia, corticobasal syndrome and 4R tauopathy]

Enjeu et contexte de la recherche La dégénérescence lobaire fronto-temporale (DLFT) est une pathologie neurodégénérative aussi fréquente que la maladie d'Alzheimer parmi les adultes de moins de 65 ans. Elle recouvre une constellation de syndromes neuropsychiatriques et moteurs dont les caractéristiques cliniques et anatomo-pathologiques se recoupent partiellement. La plupart des cas de démence sémantique ne présentent pas de troubles moteurs et révèlent à l'autopsie des lésions ubiquitine-positives. Son association à un syndrome cortico-basal et à une tauopathie 4R est donc très inhabituelle. Le cas que nous présentons est le premier à disposer d'une description clinique complète, tant sur le plan cognitif que moteur, et d'une analyse génétique et histopathologique. Résumé de l'article Il s'agit d'un homme de 57 ans, sans antécédents familiaux, présentant une démence sémantique accompagnée de symptômes inhabituels dans ce contexte, tels qu'une dysfonction exécutive et en mémoire épisodique, une désorientation spatiale et une dyscalculie. Le déclin physique et cognitif fut rapidement progressif. Une année et demie plus tard, il développait en effet des symptômes moteurs compatibles initialement avec un syndrome de Richardson, puis avec un syndrome cortico-basal. Son décès survint à l'âge de 60 ans des suites d'une pneumonie sur broncho-aspiration. L'autopsie cérébrale mit en évidence une perte neuronale et de nombreuses lésions tau-4R-positives dans les lobes frontaux, pariétaux et temporaux, les ganglions de la base et le tronc cérébral. Aucune mutation pathologique n'a été décelée dans le gène MAPT (microtubule-associated protein tau). L'ensemble de ces éléments sont discutés dans le cadre des connaissances actuelles sur la DLFT. Conclusions et perspectives Ce cas illustre le recoupement important des différents syndromes de la DLFT, parfois appelée le « complexe de Pick ». De plus, la démence sémantique pourrait s'avérer cliniquement moins homogène que prévu. Les définitions actuelles de la démence sémantique omettent la description des symptômes cognitifs extra-sémantiques malgré l'accumulation de preuves de leur existence. La faible prévalence de la démence sémantique, ainsi que des différences dans les examens neuropsychologiques, peuvent expliquer en partie la raison de cette omission. La variabilité histopathologique de chaque phénotype de DLFT peut également induire des différences dans leur expression clinique. Dans un domaine aussi mouvant que la DLFT, la co- occurrence ou la succession de plusieurs syndromes cliniques est en outre probablement la règle plutôt que l'exception.

Iowa Emergency Response Plan, October, 2010

The State of Iowa has adopted a multi-hazard approach to managing the consequences of emergency/disaster response. Underlying this approach is the principle that a standard set of generic functional capabilities can be employed to effectively address a wide variety of hazardous conditions and categories of incidents, whether these have a known probability of occurring or are totally unforeseen. Therefore, to the greatest extent possible, the activities described and assigned in this plan are organized along functional lines first, rather than by agency, type of hazard, or type of incident. Contained in this section of the Plan, known as the ―Basic Plan,‖ are instructions, policies, and explanatory information related to many or all of the agencies/entities involved in emergency/ disaster response, as well as information about the legal and administrative foundations for the Plan, the state’s characteristics and significant hazards, lines of succession for the state’s chief executive, plan activation requirements, and the structure of the response organization.
