    For decades, countries in Africa, Asia, and Latin America have remained trapped in poverty despite continuously exporting valuable commodities with which they are richly endowed – including oil, metals, plant proteins, grains, and more. This policy brief outlines one of the key causes of this harmful, unjust phenomenon: trade mispricing. More importantly, it introduces a raft of measures that can be taken to stop revenue losses from trade mispricing – in particular measures that commodity-exporting poor countries can implement unilaterally.Seit Jahrzehnten leiden viele LĂ€nder in Afrika, Asien und Lateinamerika unter Armut, obwohl sie wertvolle Rohstoffe exportieren – wie Erdöl, Edelmetalle, Kupfer, pflanzliche Rohstoffe, Getreide und vieles mehr. Eine Ursache dieses gravierenden Missstands sind Fehlbewertungen im Rohstoffhandel, die eine angemessene Besteuerung der Exporte verhindern. Dieser Policy Brief zeigt auf, was sich dagegen tun lĂ€sst. Der Schwerpunkt liegt dabei auf Massnahmen, die rohstoffexportierende arme LĂ€nder von sich aus umsetzen können

    Mainstream modes of working and consuming in rich countries are eroding our social and ecological foundations. Advocates of a shorter workweek point to a possible triple dividend from working less. This policy brief summarizes how reduced working hours could benefit our well-being, economies, and the natural world – and what measures could be taken to help make this vision a reality. Based on evidence and experience from around the world, we recommend a transformation pathway – shifting from Switzerland’s current standard workweek to a new, improved worktime status quo that could better meet our and others’ needs – and those of the planet.Die gĂ€ngigen Arbeits- und Konsummodelle in wohlhabenden LĂ€ndern untergraben unsere sozialen und ökologischen Grundlagen. BefĂŒrwortende einer kĂŒrzeren Erwerbsarbeitszeit verweisen auf eine mögliche dreifache Dividende durch weniger Arbeit. Dieser Policy Brief fasst zusammen, wie reduzierte Wochenarbeitszeiten unserem Wohlbefinden, der Wirtschaft und der Natur zugutekommen könnten – und mit welchen Massnahmen sich eine solche Vision verwirklichen liesse. GestĂŒtzt auf internationale Erkenntnisse und Erfahrungen empfiehlt ein Forschungsteam des CDE mögliche Wege weg von der derzeit in der Schweiz ĂŒblichen Wochenarbeitszeit hin zu einem neuen, besseren Status quo, der unseren BedĂŒrfnissen sowie denen anderer – und des Planeten – besser gerecht werden könnte

    Cette thĂšse s’inscrit dans le cadre de la comprĂ©hension du rĂŽle des bactĂ©ries au cours de l’altĂ©ration des silicates dans l’environnement et en particulier des matrices de confinement de dĂ©chets et de leurs analogues naturels, les verres basaltiques.L’objectif de ce travail est d’étudier les cinĂ©tiques d’altĂ©ration de silicates complexes en conditions biotiques et abiotiques dans des expĂ©riences Ă  long terme. La bactĂ©rie modĂšle choisie est une bactĂ©rie acidophile, Acidithiobacillus thiooxidans. Dans la littĂ©rature, ce genre bactĂ©rien est impliquĂ© dans l’altĂ©ration des matĂ©riaux tels que les bĂ©tons ou les pierres.L’action d’A. thiooxidans entraĂźne, comme il fallait s’y attendre, une diminution du pH des solutions d’altĂ©ration, quel que soit le matĂ©riau considĂ©rĂ©. Toutefois, avec le temps la formation d’un biofilm conduit Ă  un ralentissement de la vitesse qui peut rejoindre et mĂȘme devenir infĂ©rieure Ă  celle observĂ©e pour le milieu stĂ©rile, bien que la solution reste acide.Par ailleurs, les seuls Ă©lĂ©ments retenus prĂ©fĂ©rentiellement par le biofilm, formĂ© par A. thiooxidans Ă  la surface des matĂ©riaux Ă©tudiĂ©s, plutĂŽt que par la couche minĂ©rale d’altĂ©ration semble ĂȘtre le cuivre et le nickel alors que l’étude menĂ©e par Georges Aouad (2006) avait rĂ©vĂ©lĂ© que le biofilm produit par Pseudomonas aeruginosa Ă©tait capable de piĂ©ger de nombreux Ă©lĂ©ments potentiellement toxiques tels que le plomb, le cadmium, le nickel, le cobalt et le zinc.Le fractionnement des terres rares semble liĂ© Ă  la fois au matĂ©riau considĂ©rĂ© et Ă  la prĂ©sence ou non de notre bactĂ©rie. Le biofilm, de maniĂšre gĂ©nĂ©rale, est enrichi en terres rares lĂ©gĂšres par rapport aux terres rares lourdes. STILLE et coll. (2003, 2006) et AOUAD et coll. (2006) ont montrĂ© que la vĂ©gĂ©tation avait tendance Ă  retenir de façon plus importante les terres rares lĂ©gĂšres plutĂŽt que les terres rares lourdes, phĂ©nomĂšne Ă©galement mis en Ă©vidence dans ce travail pour le biofilm montrant peut-ĂȘtre « un effet du au bio » sur le fractionnement des terres rares.This thesis is part of understanding the role of bacteria in the weathering of silicates in the environment and in particular matrices of waste containment and their similar natural basaltic glasses.The objective of this work is to study the kinetics of weathering of silicate complex under biotic and abiotic conditions in long-term experiments by the model bacterium Acidithiobacillus thiooxidans, an acidophilic bacteria. In literature, this type of bacteria is involved in the alteration of materials such as concrete or stone.The influence of A. thiooxidans results, as expected, in a decrease of pH altering solutions, whatever the material considered. However, over time the formation of a biofilm leads to a slower speed that can reach and even become lower than that observed in the sterile environment, although the solution is acidic.Moreover, the elements retained preferentially by the biofilm formed by A. thiooxidans on the surface of materials studied, rather than the mineral layer of alteration appears to be copper and nickel, whereas the study by Georges Aouad (2006) revealed that the biofilm produced by Pseudomonas aeruginosa was able of trapping many potentially toxic elements such as lead, cadmium, nickel, cobalt and zinc.The fractionation of rare earth elements seems to be related both to the material considered and the presence or absence of this bacterium. The biofilm, in general, is rich in LREE relative to HREE. Stille et al. (2003, 2006) and Aouad et al. (2006) showed that plants tended to retain the LREE more than the HREE, a phenomenon also demonstrated in this work by the biofilm involving a possible biological effect on fractionation of rare earths elements

    Vielfalt ist die Quelle des Lebens: Herausforderungen und Handlungsbedarf fĂŒr die Förderung der AgrobiodiversitĂ€t

    For millennia, humankind’s food security and resilience were ensured by thousands of cultivated plant species, dozens of domesticated animal species, and the wider biodiversity from which they derive. But with the expansion of industrial agriculture and globalized standardized food systems, this long-running agricultural biodiversity has fallen steeply. Today, just three plant species account for half of all plant-based food calories,1 and only four animal species account for the vast majority of meat supplies.2 Looking ahead, restoring agrobiodiversity – the richness of what we cultivate, breed, consume, and conserve in the wild – is crucial to ensure resilient food systems against the backdrop of climate change. In particular, we must safeguard the livelihoods of the “guardians of agrobiodiversity”: approximately 500 million small farms across the world – particularly those in the global South.3 This factsheet outlines causes and consequences of agrobiodiversity loss, areas of promise, and options for policy and research.Depuis des millĂ©naires, la sĂ©curitĂ© alimentaire et la rĂ©silience de l’humanitĂ© sont assurĂ©es par des milliers d’espĂšces de plantes cultivĂ©es, des dizaines d’espĂšces animales domestiquĂ©es et la biodiversitĂ© dont elles proviennent. Mais la mondialisation de l’agriculture industrielle et les systĂšmes alimentaires normĂ©s ont fait chuter l’agrobiodiver-sitĂ©:trois espĂšces vĂ©gĂ©tales fournissent la moitiĂ© des calories vĂ©gĂ©tales1 et quatre espĂšces animales produisent presque toute la viande.2 Il est donc crucial de restaurer l’agrobiodiversitĂ© – qui reprĂ©sente la richesse de ce que nous cultivons, Ă©levons, consommons et protĂ©geons dans la nature – afin de conserver des systĂšmes alimentaires rĂ©silients, dans un contexte de changement climatique. Il faut d’abord sauvegarder les conditions de vie des «gar-diens de l’agrobiodiversité», les quelques 500 millions de petites fermes dans le monde, surtout dans les pays du Sud.3 Cette fiche d’information dĂ©finit les causes et consĂ©quences de la perte d’agrobiodiversitĂ©, les domaines prometteurs et les opportunitĂ©s pour les politiques et la recherche.Jahrtausendelang wurde die ErnĂ€hrungssicherheit und WiderstandsfĂ€higkeit des Menschen durch Tausende von Kulturpflanzensorten, Dutzenden von Haustierarten sowie durch die nicht direkt genutzte BiodiversitĂ€t, gewĂ€hr-leistet. Die starke Ausweitung der agroindustriellen Landwirtschaft fĂŒhrte zu globalen, standardisierten Nahrungs-systemen. Damit einher ginge eine drastische Verringerung der Vielfalt von Pflanzensorten und Tierrassen in der Landwirtschaft. Heute liefern nur drei Pflanzenarten die HĂ€lfte aller pflanzlichen Nahrungskalorien,1 und nur vier Tierarten sind an der Produktion des Grossteils der globalen Fleischversorgung beteiligt.2 Die Wiederherstellung der AgrobiodiversitĂ€t – die Vielfalt dessen, was wir anbauen, zĂŒchten, konsumieren und in freier Wildbahn erhalten – ist von entscheidender Bedeutung, um widerstandsfĂ€hige Nahrungssysteme vor dem Hintergrund des Klimawandels sicherzustellen. Dabei gilt es, den «HĂŒtern der AgrobiodiversitĂ€t» - die rund 500 Millionen kleinen Landwirtschafts-betrieben auf der ganzen Welt, vor allem im globalen SĂŒden3 - den Lebensunterhalt zu sichern. Dieses Faktenblatt beschreibt Ursachen und Folgen des AgrobiodiversitĂ€tsverlusts, und zeigt auf, welche Wege Politik und Forschung einschlagen könnten

    Marginalizing Progressives? Newspaper Coverage of Bernie Sanders in the ‘Invisible Primary’: A Critical Discourse Analysis

    No full text
    The present thesis uses methods of Critical Discourse Analysis to examine 16 front-page newspaper articles, from The New York Times and The Washington Post, covering progressive presidential candidate Bernie Sanders during the 2015 “invisible primary”. In particular, this thesis investigates how Sanders and his supporters were represented, linguistically and visually, and whether these representations – formulated as “interpretive frames” – appear more legitimizing or delegitimizing. In the crucial prevoting period of the invisible primary, the media largely have the power to construct the identity of relatively unknown candidates, such as Sanders, in the minds of the national public. The 2015/16 election season occurred against the backdrop of extreme levels of economic inequality and related societal ills, which have arguably arisen from four decades of neoliberal policies implemented by successive American presidents from both major political parties.The findings of the analysis appear to confirm a concerning pattern of largely delegitimizing US media coverage (or omission) of progressive political candidates and social movements going back several decades. In the articles analysed, Sanders was represented using interpretive frames casting him as an extreme leftist, angry and impersonal, or marginal and old. Only one major interpretive frame – representing him as a skilful, pragmatic politician – appeared legitimizing. Similarly, Sanders’ supporters were largely framed as activists, excitable fans, or divided into narrow identity categories (e.g. “white liberals”) that appear delegitimizing when considered opposite the shared economic struggles that many of them likely face. Given the liberal reputation of The New York Times and moderate image of The Washington Post, the results raise further doubts about the ideological diversity of the mainstream American public sphere
