Kinds of France Selected AbstractsCharacterizing sediment acid volatile sulfide concentrations in European streamsENVIRONMENTAL TOXICOLOGY & CHEMISTRY, Issue 1 2007G. Allen Burton Abstract Sediment acid volatile sulfide (AVS) concentrations were measured in wadeable streams of a wide variety of ecoregions of western Europe (84 sites in 10 countries and nine ecoregions) to better understand spatial distribution and ecoregion relationships. Acid volatile sulfide has been shown to be a major factor controlling the bioavailability and toxicity of many common trace metals, such as Cd, Cu, Ni, Pb, and Zn. Sediment characteristics varied widely. The ratio of the sum of the simultaneously extracted metals (SEM) to AVS ranged from 0.03 to 486.59. The ,SEM-AVS ranged from ,40.02 to 17.71 ,mol/g. On a regional scale, sediment characteristics such as dominant parent soil material showed significant trends in AVS distribution and variation by ecoregion. Total Fe and Mn were correlated weakly with SEM concentrations. Three AVS model approaches (i.e., the SEMAVS ratio, SEM-AVS difference, and carbon normalization) were compared at threshold exceedance levels of SEM/AVS > 9, SEM-AVS > 2, and SEM-AVS/foc > 150 ,mol/g organic carbon (OC). Only 4.76% of the sediments exceeded all three AVS thresholds; 22.6% of the sediments exceeded two models; and 13% of the sediments exceeded one model only. Using the SEM:AVS, SEM-AVS, and fraction of organic carbon models, and including site-specific data and regional soil characteristics, ecoregions 1 (Portugal), 3 (Italy), 4 (Switzerland), and 9 (Belgium/Germany) had the highest potential metals toxicity; ecoregions 13 and 8 (Belgium/France) showed the lowest potential toxicity. However, because AVS can vary widely spatially and temporally, these data should not be considered as representative of the sampled ecoregions. The general relationship between AVS levels and sediment characteristics provides some predictive capability for wadeable streams in the European ecoregions. [source] PENSION REFORM, POLITICAL PRESSURE AND PUBLIC CHOICE , THE CASE OF FRANCEECONOMIC AFFAIRS, Issue 4 2008Laura Thompson An ageing population and generous public sector pensions have put significant pressure on the funding of the French pension system making a reduction in the scope of state pension schemes imperative. Yet, as public-choice theory would predict, lobbying by interest groups has made reform difficult to achieve.

[source] The French Riots: Questioning Spaces of Surveillance and SovereigntyINTERNATIONAL MIGRATION, Issue 2 2006Susan Ossman ABSTRACT This paper examines the riots in France in late 2005 in terms of how they lead to a reconceptualization of the spaces of danger, culture, territory, and sovereignty. It traces a brief history of danger zones and immigration, noting how these two terms have increasingly overlapped. We analyse key discursive formations - legal, political, social scientific, and media - whose explanation for the emergence of the "immigrant" delinquent is linked to what is identified as a culture of poverty. They provide a sustained examination of recent legal reforms of juvenile law as well as judicial practices within the juvenile justice system to show the systematic exclusionary practices of what is claimed to be a colour blind republican system. They reveal a consensus across the political spectrum and among police, prosecutors, investigating magistrates, and new security experts on the need to privilege accountability, restitution, and retribution in the treatment of juvenile offenders. We present evidence from interviews and ethnographic observation among youths of all backgrounds. Ironically, while the children of immigrants seek to claim a voice in the national community, their peers from more privileged social milieu express increasing distance from national concerns, seeking to lead lives as Europeans or global citizens. We end by arguing that this needs to be taken into account in any analysis of frustrated and disenfranchised suburban youths. A transnational or supra-national sociology that accounts for the itineraries of immigrants of all kinds must be developed. LES ÉMEUTES EN FRANCE: QU'EN EST-IL DES ESPACES DE SURVEILLANCE ET DE LA SOUVERAINETÉ? Les émeutes qui ont éclaté en France fin 2005 conduisent à une reconceptualisation des notions de danger, de culture, de territoire et de souveraineté. Cet article, qui présente un bref historique des zones de danger et de l'immigration, montre combien ces deux concepts ont tendance à se rejoindre. Nous analysons les principales formations discursives - juridique, politique, sociale, scientifique et médiatique - qui expliquent l'émergence du délinquant « immigré » en l'associant à ce qui est décrit comme une culture de la pauvreté. Elles nous offrent un examen soutenu des réformes récentes du droit des mineurs et des pratiques judiciaires au sein du système de justice des mineurs, et montrent les pratiques d'exclusion systématiques d'un système républicain prétendant ignorer les préjugés raciaux. Elles montrent que, d'un bout à l'autre de l'échiquier politique, dans la police, chez les procureurs, les juges d'instruction et les nouveaux spécialistes de la sécurité, il existe un consensus sur la nécessité de privilégier l'obligation de rendre des comptes, la réparation et le châtiment dans le traitement des mineurs délinquants. Nous étayons cet argument à partir d'entretiens et d'observations ethnographiques de jeunes de tous les milieux. De façon assez ironique, alors que les enfants d'immigrés veulent avoir leur mot à dire au sein de la communauté nationale, les enfants de milieux plus privilégiés se disent de moins en moins concernés par les préoccupations nationales et cherchent à mener une vie d'Européen ou de citoyen du monde. En conclusion, nous avançons que cette situation doit être prise en compte dans toute analyse des jeunes des banlieues frustrés et privés de droits. Une sociologie transnationale ou supranationale qui rendrait compte des itinéraires des immigrés, tous milieux sociaux confondus, serait une bonne chose. LAS REVUELTAS FRANCESAS: CUESTIONAMIENTO DE LOS ESPACIOS DE VIGILANCIA Y SOBERANÍA En este artículo se examinan las revueltas de Francia a finales de 2005 en la medida en que conducen a una reconceptualización de los espacios de peligro, cultura, territorio y soberanía. Se traza una breve historia de las zonas de peligro y de la inmigración, señalando a la atención cómo estos dos conceptos han ido solapándose crecientemente. Se analizan formaciones discursivas clave -jurídicas, políticas, propias de las ciencias sociales y mediáticas - cuyas explicaciones de la aparición del delincuente "inmigrante" se vinculan con lo que se ha descrito como una cultura de la pobreza. Se ofrece un examen sostenido de las recientes reformas jurídicas de las leyes sobre los menores, así como de las prácticas judiciales dentro del sistema de justicia de menores para mostrar las prácticas de exclusión sistemática de lo que se considera que es un sistema republicano daltónico. Se revela un consenso entre los políticos y entre la policía, los fiscales, los jueces de instrucción y los nuevos expertos en seguridad sobre la necesidad de dar prelación a la asunción de responsabilidades, la restitución y la retribución en el tratamiento de los menores delincuentes. Se presentan pruebas extraídas de entrevistas y de la observación etnográfica de los jóvenes de todos los ambientes. Irónicamente, mientras los hijos de inmigrantes tienden a reclamar una voz en la comunidad nacional, sus iguales de medios sociales más privilegiados expresan un creciente distanciamiento de las preocupaciones nacionales y prefieren vivir como europeos o ciudadanos del mundo. Se termina arguyendo que es preciso tener en cuenta este factor en cualquier análisis de los jóvenes frustrados y privados de voto que viven en los barrios periféricos. Será preciso desarrollar una sociología transnacional o supranacional que explique los itinerarios de todo tipo de inmigrantes. [source] The October Riots in France: A Failed Immigration Policy or the Empire Strikes Back?INTERNATIONAL MIGRATION, Issue 2 2006Yvonne Yazbeck Haddad ABSTRACT In October 2005, the predominately Arab-immigrant suburbs of Paris, Lyon, Lille and other French cities erupted in riots by socially alienated teenagers, many of them second- or third-generation immigrants. For many French observers, it was a painful reminder that France's immigration policy had, quite bluntly, failed. The grand French ideal of égalité, the equality of all citizens of the Republic, itself a by-product of France's colonial past, demonstrated its incompatibility with twenty-first century reality. The French immigration experience is markedly different than those of other European countries, as France's is tainted by colonial history, republican idealism, a rigidly centralized government structure, and deep-seeded traditions of xenophobia. Indeed, the nineteenth century French policy of the mission civilicatrice (civilizing mission) still influences French policy toward its immigrants today: rather than accept cultural differences, the French government demands that all its citizens adhere to a rigid and exclusive "French" identity. As such, the children of the generation of immigrants that the French government actively brought to France to fuel its post-war expansion now find themselves unemployed and socially marginalized. Government social structures meant to ease the disparity between social classes, such as public housing and education, generally do more to aggravate problems than to solve them; public housing is woefully inadequate and the education structure institutionalizes the poor quality of schools in immigrant communities. Despite this generally poor outlook, the French have recently made some progress toward better integration of their immigrant communities, though these efforts are generally met with wide-spread demagogic and populist opposition. LES ÉMEUTES D'OCTOBRE EN FRANCE: ÉCHEC DE LA POLITIQUE D'IMMIGRATION OU L'EMPIRE CONTRE-ATTAQUE? En octobre 2005, dans les banlieues de Paris, Lyon, Lille et d'autres villes françaises, oú prédominent les immigrés arabes, des émeutes ont éclaté, menées par des adolescents socialement aliénés, dont beaucoup étaient des immigrés de deuxième ou troisième génération. Pour nombre d'observateurs français, ces événements ont douloureusement confirmé que la politique d'immigration de la France était un échec cuisant. Le magnifique idéal français d'égalité de tous les citoyens de la République, lui-même un sous-produit du passé colonial de la France, se révélait décidément incompatible avec la réalité du 21e siècle. En matière d'immigration, l'expérience de la France est sensiblement différente de celle des autres pays européens, la France étant marquée par une histoire coloniale, un idéalisme républicain, une structure gouvernementale rigidement centralisée et une tradition de xénophobie profondément ancrée. D'ailleurs, l'approche française de la mission civilisatrice, qui avait cours au 19e siècle, continue d'influencer la politique de la France à l'égard de ses immigrés: plutôt que d'accepter les différences culturelles, le Gouvernement français exige que tous les citoyens adhèrent à une identité « française » à la fois rigide et exclusive. Les enfants des immigrés que le Gouvernement français avait fait venir en France pour soutenir son expansion d'après-guerre se retrouvent maintenant au chômage et socialement marginalisés. Les structures sociales gouvernementales destinées à atténuer les disparités entre classes sociales, notamment le logement social et l'enseignement, font souvent plus pour aggraver les problèmes que pour les résoudre. Les logements sociaux sont cruellement insuffisants et le système d'enseignement institutionnalise la mauvaise qualité des établissements scolaires fréquentés par les communautés d'immigrés. Malgré ces perspectives généralement médiocres, les Français ont fait des progrès dans le sens d'une meilleure intégration de ces communautés, bien que ces efforts se heurtent généralement à une importante opposition teintée de démagogie et de populisme. LAS REVUELTAS DE OCTUBRE EN FRANCIA: ¿UNA POLÍTICA DE INMIGRACIÓN ERRÓNEA O EL IMPERIO CONTRAATACA? En octubre de 2005, los barrios donde predomina la inmigración árabe de París, Lyon, Lille y otras ciudades francesas fueron el escenario de revueltas de adolescentes socialmente alienados, muchos de ellos inmigrantes de segunda o tercera generación. Para muchos observadores franceses, fue un doloroso recordatorio de que, con bastante claridad, la política de inmigración de Francia había fracasado. El gran ideal francés de l'égalité, es decir, la igualdad de todos los ciudadanos de la República, consecuencia en sí misma del pasado colonial francés, demostró su incompatibilidad con la realidad del siglo XXI. La experiencia de la inmigración francesa es muy distinta a la de otros países europeos, ya que Francia está marcada por su historia colonial, el idealismo republicano, una estructura gubernamental estrictamente centralizada y unas tradiciones arraigadas de xenofobia. Ciertamente, la política francesa del siglo XIX de la mission civilisatrice (misión civilizadora) influye aún hoy en la política francesa sobre inmigración: más que aceptar las diferencias culturales, el Gobierno francés exige que todos sus ciudadanos se adhieran a una identidad "francesa" rígida y exclusiva. Los hijos de la generación de inmigrantes a los que el Gobierno francés alentó activamente a ir a Francia para impulsar la expansión de la postguerra se encuentran ahora sin trabajo y marginados de la sociedad. Las estructuras sociales del Estado, encaminadas a disminuir la disparidad entre clases sociales, tales como la vivienda y la educación públicas, contribuyen generalmente a agravar los problemas más que a solucionarlos: las viviendas públicas son lamentablemente inadecuadas y la estructura educativa institucionaliza la escasa calidad de las escuelas de las comunidades de inmigrantes. A pesar de este panorama en general poco prometedor, los franceses han logrado recientemente algunos progresos hacia una mejor integración de sus comunidades inmigrantes, aunque estos esfuerzos se encuentran a menudo con una oposición demagógica y populista ampliamente extendida.

[source] SEDIMENTARY IMPRINT OF MICROCYSTIS AERUGINOSA (CYANOBACTERIA) BLOOMS IN GRANGENT RESERVOIR (LOIRE, FRANCE),JOURNAL OF PHYCOLOGY, Issue 3 2007Delphine Latour Analysis of a sediment core taken from the Grangent reservoir in 2004 showed the presence of high concentrations of Microcystis aeruginosa Kütz. colonies at the sediment surface (250 colonies,·,mL sediment,1) and also at depths of 25,35 cm (2300 colonies·mL sediment,1) and 70 cm (600 colonies,·,mL sediment,1). Measurements of radioactive isotopes (7Be, 137Cs, and 241Am) along with photographic analysis of the core were used to date the deep layers: the layer located at ,30 cm dates from summer 2003, and that located at ,70 cm from 1990 to 1991. The physiological and morphological conditions of those benthic colonies were compared with those of planktonic colonies using several techniques (environmental scanning electron microscopy [ESEM], TEM, DNA markers, cellular esterases, and toxins). The ESEM observations showed that, as these colonies age, peripheral cells disappear, with no cells remaining in the mucilage of the deepest colonies (70 cm), an indication of the survival thresholds of these organisms. In the benthic phase, the physiological conditions (enzyme activity, cell division, and intracellular toxins) and ultrastructure (particularly the gas vesicles) of the cells surviving in the heart of the colony are comparable to those of the planktonic form, with all the potential needed for growth. Maintaining cellular integrity requires a process that can provide sufficient energy and is expressed in the reduced, but still existing, enzymatic activity that we measured, which is equivalent to a quiescent state. [source] DETECTION OF LOCAL INTERACTIONS FROM THE SPATIAL PATTERN OF NAMES IN FRANCE,JOURNAL OF REGIONAL SCIENCE, Issue 1 2008Keith Head ABSTRACT Using data on the geographic distribution of names in France, we investigate the social transmission of parental preferences. Drawing on recent work on nonmarket interactions, we develop a linear discrete choice model that relates choices made in one location to those made in nearby areas. We explain the shares of parents that give their children Saint, Arabic, and American-type names. We also examine the effect of distance between locations on differences in naming patterns. We find that the importance of geographic distance is declining over time while differences in class and national origins have increasing explanatory power. [source] THE DOUET ALIGNMENT ON THE ISLAND OF HOEDIC (MORBIHAN, FRANCE): NEW INSIGHTS INTO STANDING STONE ALIGNMENTS IN BRITTANYOXFORD JOURNAL OF ARCHAEOLOGY, Issue 3 2009JEAN-MARC LARGE Summary The island of Hoedic in southern Brittany has numerous archaeological remains of later prehistoric date. It became famous through the discovery in the 1930s of a Mesolithic cemetery, but the island also has abundant archaeological evidence from the earliest Neolithic period onwards. These include several megalithic monuments, the most significant being alignments of standing stones. One of these alignments has recently been excavated, and investigation of another is in progress. The discoveries resulting from this work provide new insights into the origin of the phenomenon, its chronological and cultural context and the techniques that were used to create these structures. Above all, it offers a new approach to considering the meaning of these alignments. [source] INTRAMARGINAL VEINED LAURACEAE LEAVES FROM THE ALBIAN,CENOMANIAN OF CHARENTE-MARITIME (WESTERN FRANCE)PALAEONTOLOGY, Issue 2 2009CLÉMENT COIFFARD Abstract:,Eucalyptolaurus depreii gen. et sp. nov. is proposed for angiosperm leaves newly collected from uppermost Albian , lowermost Cenomanian of Charente-Maritime (western France). They consist of simple, narrow, elongate laminas with entire margins and intramarginal veins. The epidermal cells of adaxial cuticle shows small, rounded, blunt papillae outward that protrude inward and fuse together as rolls along and parallel to the margins, while the adaxial cuticle bears brachyparacytic stomatal apparatus that exhibit sunken guard cells and hair bases consisting of a thick-walled pore surrounded by radially arranged differentiated cells. Resin bodies occur inside the mesophyll. These characters closely resemble the lauroid taxa ,Myrtophyllum' and Pandemophyllum from the Cenomanian of the Czech Republic and Dakota (USA) respectively. The narrow angle of basilaminar secondaries and the whole suite of features in the guard cells (sunken guard cells embedded into subsidiary cells and stomatal ledges) strongly support close affinity with the Lauraceae. From the Cenomanian lauraceous reproductive organs and their related leaves already showed high disparity and diversity. In addition they displayed a broad ecological range from freshwater floodplains to brackish swamps. This combined to high diversity of reproductive organs suggest ecological radiation of Lauraceae by the Cenomanian.

Monetary transfers allocate predominantly towards the large number of elderly parents in the country of origin, while the smaller number of migrant parents in France are more likely to receive time transfers. Our econometric results suggest that monetary transfers are more consistent with the altruistic hypothesis. Furthermore, while the donor's labour participation increases the propensity to give money, there is no negative relationship between time transfers and the labour participation of the donor. [source] ANTIMONATE OPAQUE GLAZE COLOURS FROM THE FAIENCE MANUFACTURE OF LE BOIS D'ÉPENSE (19TH CENTURY, NORTHEASTERN FRANCE)*ARCHAEOMETRY, Issue 5 2009M. MAGGETTI Three types of antimony-based, opaque ceramic colours were used in the faience workshop of Le Bois d'Épense during the first decades of the 19th century; that is, yellow, tawny and green. Yellow is generated by lead antimonate crystals (Naples Yellow), which are incorporated into an uncoloured glass matrix. According to SEM,EDS measurements, these pigments contain iron. The tawny colour is the optical result of the combined presence of similar yellow, iron-bearing lead antimonate particles in a Fe-rich, brownish glass matrix. The green opaque colour is produced by the combination of a blue cobalt glass and yellow Pb,Sn,Fe-antimonate crystals. Cores of zoned pigments lighten the recipes, according to which the pigments were produced. First, they were synthesized by calcination, ground and then mixed with a colourless, brown or blue glass powder. The resulting powder mixture was added to a liquid agent and used as high-temperature ceramic colour. [source] CLAY RESOURCES AND TECHNICAL CHOICES FOR NEOLITHIC POTTERY (CHALAIN, JURA, FRANCE): CHEMICAL, MINERALOGICAL AND GRAIN-SIZE ANALYSES*ARCHAEOMETRY, Issue 1 2007R. MARTINEAU Many authors have considered pottery manufacturing constraints and sociocultural elements as factors in change in past civilizations over time. The main issue of this research is to better understand the reasons for changes, or choices, in pottery raw materials. The very precise and detailed stratigraphy and cultural succession of occupations is based on dendrochronological data from the lake-dwelling sites of Chalain (Jura, France). Petrographic, palaeontological and chemical analyses were used to determine the nature and origins of the raw materials used by the Neolithic potters. Stratigraphy and dendrochronological data were used to reconstruct in detail the evolution dynamics of fabric changes. Several raw material sources were identified for many of the pottery groups. Each of them was sampled for qualitative experimental tests of pottery forming. The experimental results show a high variability between the sediments tested. This variability was quantitatively estimated by XRF, XRD, the Rietveld method, calcium carbonate quantification and laser grain-size analyses of matrices, indirect measures of plasticity. These analytical results allow a better understanding of the differences observed in the experimental tests. On the basis of these experimental and analytical results, changing parameters such as pottery manufacturing constraints, mineralogical characteristics of raw materials and sociocultural factors are considered. In conclusion, all the social and technical parameters, in each archaeological context, must be taken into account for a better understanding of the changes occurring throughout the chronological sequence. [source] THE CONDITION OF MUSIC: WAGNERISM AND PRINTMAKING IN FRANCE AND BRITAINART HISTORY, Issue 3 2009RACHEL SLOAN Scholarship on the impact of Richard Wagner's music and aesthetic theories has traditionally concentrated on fin-de-siècle France. Aubrey Beardsley's Wagnerian prints have recently been the subject of several significant studies, but they have been examined in a British context with little reference to earlier or concurrent developments in France. This article serves as a case study of Anglo-French artistic exchange at the fin-de-siècle, examining some points of interaction between Beardsley and two key French Wagnerian artists, Henri Fantin-Latour and Odilon Redon, in order to throw more light on the complex mixture of political, social and aesthetic discourses that informed all three artists' interest in the intersection of music and the visual arts, as well as their Wagnerian pictorial languages. [source] ,MERELY MECHANICAL': ON THE ORIGINS OF PHOTOGRAPHIC COPYRIGHT IN FRANCE AND GREAT BRITAINART HISTORY, Issue 1 2008ANNE MCCAULEY The invention of the medium of photography and its commercialization as a cheap multiple during the 1850s and 1860s led to challenges to extant copyright laws in France and Great Britain. This paper traces the ways that debates over photographic copyright confronted current understandings of originality and mechanization and repeated arguments that had already been raised by laws governing prints and casts. The British Fine Arts Copyright Act of 1862, which extended statutory protection to all photographs, is contrasted with French cases, which struggled to accommodate photographs within the fine arts as defined by the copyright law of 1793. [source] Role of Corridors in Plant Dispersal: an Example with the Endangered Ranunculus nodif lorusCONSERVATION BIOLOGY, Issue 2 2003Florian Kirchner But the few experimental studies supporting the usefulness of corridors have all concerned animal species. We investigated the role of corridors in seed dispersal, studying population genetic and demographic structure in metapopulations of the rare, pond-dwelling, autogamous plant species Ranunculus nodiflorus L. in the Fontainebleau Forest ( France ). Differentiation on three polymorphic isozyme markers was strong among local populations ( ponds ) within metapopulations ( sites ) and moderate among metapopulations. Partial Mantel tests revealed that the connection of ponds through temporarily flooded natural corridors, facilitating seed migration, had a strong negative effect on genetic differentiation between local populations and that a pond was more likely to be colonized when connected by corridors to other occupied ponds. Thus, corridors are probably a key element of landscape structure for metapopulation dynamics in R. nodiflorus. From a conservation perspective, our results suggest that corridors could increase the chance of persistence of plant species living in fragmented habitats by promoting seed dispersal between habitat patches. Resumen: La propuesta de que la migración de organismos entre parches de hábitat puede ser incrementada por corredores ha sido muy discutida en biología de la conservación. Pero los pocos estudios experimentales que apoyan la utilidad de los corredores han sido enfocados hacia especies de animales. Investigamos el papel de los corredores en la dispersión de semillas, estudiando la genética poblacional y la estructura demográfica en metapoblaciones de la especie de planta rara, autógama, habitante de estanques Ranunculus nodiflorus L. en el bosque Fontainebleau ( Francia ). La diferenciación de tres isozimas polimórficas marcadoras fue fuerte entre las poblaciones locales ( estanques ) dentro de metapoblaciones ( sitios ) y fue moderada entre metapoblaciones. Las pruebas parciales de Mantel revelaron que la conexión de estanques a través de corredores naturales inundados facilitando la migración de semillas, tuvo un efecto negativo fuerte en la diferenciación genética entre poblaciones locales y que un estanque fue más probable de ser colonizado cuando se conectaba por corredores con otros estanques ocupados. Por lo tanto, los corredores probablemente son un factor clave de la estructura del paisaje para dinámicas metapoblacionales en R. nodiflorus. Desde una perspectiva de conservación, nuestros resultados sugieren que los corredores podrían incrementar la probabilidad de persistencia de especies de plantas que viven en hábitats fragmentados al promover la dispersión de semillas entre parches de hábitats. [source] Contamination by nickel, copper and zinc during the handling of euro coinsCONTACT DERMATITIS, Issue 4 2003Paul-Guy Fournier The introduction of the euro has revived interest in the risk of nickel allergy due to the handling of coins. In the present work, the transfer of metallic contamination during the manipulation of coins is examined by means of leaching experiments and manipulation tests. It is shown that pre-existing metallic species present on the surface of the coins are the major source of contamination during manipulation, and that friction inherent to everyday usage contributes predominantly to their transfer to the hands. The comparison of coins as to their relative risks of metal contamination should therefore rely on tests that simulate the friction inherent in everyday human handling. Carrying out such tests with the newly issued 1, and 2, pieces, we find, contrary to long-term leaching measurements, that the euros release less nickel than previously circulated pure-nickel coins, but that this decrease is less pronounced than might have been hoped for on the basis of their surface composition. When the coins are rubbed to a shiny polish before manipulation, contamination of the fingers is reduced by more than a factor of 10. A comparison of coins used in France indicates that the introduction of the common currency has led to a fourfold reduction in contamination by nickel, while causing a 45% increase in contamination by copper. [source] An epidemic of allergic contact dermatitis due to epilating productsCONTACT DERMATITIS, Issue 2 2002A. Goossens Over a period of 19 months, 33 cases of acute allergic contact dermatitis from Veet® epilating waxes and/or the accompanying tissue (Reckitt Benckiser, Massy, France) were observed in France and Belgium. The lesions started on the legs and spread to other parts of the body, especially the face, and were sometimes so severe that hospitalization and/or systemic corticosteroids were required. Primary sensitization occurred as early as after the first application in several patients. Patch tests were performed in 26 of the patients and produced strong positive reactions to the tissue (25 times) and/or the wax (13 times). The allergenic culprits in the wax were modified-colophonium derivatives (colophonium in the standard series testing negatively in all except 4 patients), while methoxy PEG-22/dodecyl glycol copolymer and to a lesser degree lauryl alcohol turned out to be the main causal allergens in the tissue. [source] Adventures in multivalency, the Harry S. Fischer memorial lecture CMR 2005; Evian, FranceCONTRAST MEDIA & MOLECULAR IMAGING, Issue 1 2006Michael F. Tweedle Abstract This review discusses multivalency in the context of drug discovery, specifically the discovery of new diagnostic imaging and related agents. The aim is to draw attention to the powerful role that multivalency plays throughout research involving molecular biology, in general, and much of biochemically targeted contrast agent research, in particular. Two examples from the author's laboratory are described. We created small (,5,kDa) peptide ,dimers' composed of two different, chemically linked peptides. The monomer peptides both bound to the same target protein with Kd,,,100,s,nM, while the heterodimers had sub-nM Kd values. Biological activity was evident in the heterodimers where none or very little existed in homodimers, monomers or monomer mixtures. Two different tyrosine kinases (KDR and C-Met) and four peptide families produced consistent results: multivalent heterodimers were uniquely different. The second example begins with making two micron ultrasound bubbles coated with the peptide, TKPPR (a Tuftsin antagonist) as a negative control for bubbles targeted with angiogenesis target-binding peptides. Unexpected binding of a ,negative' control, (TKPPR)-targeted bubble to endothelial cells expressing angiogenesis targets, led to the surprising result that TKPPR, only when multimerized, binds avidly, specifically and actively to neuropilin-1, a VEGF co-receptor. VEGF is the primary stimulator of angiogenesis. Tuftsin is a small peptide (TKPR) derived from IgG that binds to macrophages during inflammation, and has been studied for over 30 years. The receptor has never been cloned. The results led to new conclusions about Tuftsin, neuropilin-1 and the purpose, up to now unknown, of exon 8 in VEGF. Multivalency can be used rationally to solve practical problems in drug discovery. When targeting larger structures, multivalency is frequently unavoidable, and can lead to unpredictable and useful biochemical information, as well as to new drug candidates.

[source] Competing Rationales for Corporate Governance in France: Institutional Complementarities between Financial Markets and Innovation SystemsCORPORATE GOVERNANCE, Issue 2 2008Soo H. Lee ABSTRACT Manuscript Type: Conceptual Research Question/Issue: This paper identifies the causes and consequences of corporate governance reform with reference to the French case. By disaggregating institutional complementarities into global and domestic dimensions, we analyze the path of institutional change compelled by financial efficiency and cooperative innovation. Research Findings/Results: Our analysis of the French case shows that both converging and diverging forces of institutional change coexist, shaping selective responses to globalization. While the adoption of the shareholder model is necessary for resource acquirement from the global capital markets, resource allocation in the cooperative innovation systems reinforces the stakeholder model. The French case confirms the sustainability of distinctive institutional complementarities, albeit with selective adaptation based on a sense-making social compromise. Theoretical Implications: The French case reminds us of the importance of distinctive institutional traditions and dominant social rationalities to understand the underlying logic of governance reform. The comparative research on corporate governance needs to address not just the cross-country variations in institutional arrangements and practices, but also the clash of competing rationales for reform explicitly in comparative terms within a single country context. Practical Implications: For foreign investors, it is vital to understand the unique institutional environment of state-centred stakeholder economies if they are to negotiate the best terms of return and to avoid unnecessary conflicts. French managers are expected to devise strategic choices responding to the competing rationales of governance. Managerial sense-making is essential for achieving sound long-term performance, upon which the legitimacy and sustainability of the constellation of selective governance rests. [source] POLICE, MINORITIES, AND THE FRENCH REPUBLICAN IDEAL,CRIMINOLOGY, Issue 4 2003RENÉE ZAUBERMAN This paper examines the strained relationship between French police agencies and ethnic minorities and discusses evidence of ethnic discrimination by the police and the criminal justice system. Until recently, the idea that ethnic composition of a police force ought to reflect, to some degree, the community it polices, seemed odd in France. We argue that there are two main reasons for this viewpoint: first, a conception of the role of the police in the State as accountable to the government rather than to the citizens; secondly, a conception of Republic and citizenship denying any political significance to the personal identities of citizens. We conclude that ethnic diversification of police forces is but one aspect of a more encompassing struggle against discrimination that requires a degree of accommodation with the present legal and statistical invisibility of racial/ethnic groups. [source] Compassion and Repression: The Moral Economy of Immigration Policies in FranceCULTURAL ANTHROPOLOGY, Issue 3 2005Didier Fassin Immigration policies in Europe in the last three decades have become increasingly restrictive. During the 1990s, political asylum lost much of its legitimacy, as new criteria based on humanitarian claims became more common in appeals for immigration. Asylum seekers were increasingly identified as illegal immigrants and therefore candidates for expulsion, unless humanitarian reasons could be found to requalify them as victims deserving sympathy. This substitution of a right to asylum by an obligation in terms of charity leads to a reconsideration of Giorgio Agamben's separation of the humanitarian and the political, suggesting instead a humanitarianization of policies. Sangatte Center, often referred to as a transit camp, became a symbol of this ambiguous European treatment of the "misery of the world" and serves here as an analytical thread revealing the tensions between repression and compassion as well as the moral economy of contemporary biopolitics. [source] Optimizing flow cytometric DNA ploidy and S-phase fraction as independent prognostic markers for node-negative breast cancer specimensCYTOMETRY, Issue 3 2001C.B. Bagwell Abstract Developing a reliable and quantitative assessment of the potential virulence of a malignancy has been a long-standing goal in clinical cytometry. DNA histogram analysis provides valuable information on the cycling activity of a tumor population through S-phase estimates; it also identifies nondiploid populations, a possible indicator of genetic instability and subsequent predisposition to metastasis. Because of conflicting studies in the literature, the clinical relevance of both of these potential prognostic markers has been questioned for the management of breast cancer patients. The purposes of this study are to present a set of 10 adjustments derived from a single large study that optimizes the prognostic strength of both DNA ploidy and S-phase and to test the validity of this approach on two other large multicenter studies. Ten adjustments to both DNA ploidy and S-phase were developed from a single node-negative breast cancer database from Baylor College (n = 961 cases). Seven of the adjustments were used to reclassify histograms into low-risk and high-risk ploidy patterns based on aneuploid fraction and DNA index optimum thresholds resulting in prognostic P values changing from little (P < 0.02) or no significance to P < 0.000005. Other databases from Sweden (n = 210 cases) and France (n = 220 cases) demonstrated similar improvement of DNA ploidy prognostic significance, P < 0.02 to P < 0.0009 and P < 0.12 to P < 0.002, respectively. Three other adjustments were applied to diploid and aneuploid S-phases. These adjustments eliminated a spurious correlation between DNA ploidy and S-phase and enabled them to combine independently into a powerful prognostic model capable of stratifying patients into low, intermediate, and high-risk groups (P < 0.000005). When the Baylor prognostic model was applied to the Sweden and French databases, similar significant patient stratifications were observed (P < 0.0003 and P < 0.00001, respectively). The successful transference of the Baylor prognostic model to other studies suggests that the proposed adjustments may play an important role in standardizing this test and provide valuable prognostic information to those involved in the management of breast cancer patients.
