The Fair Trade and co-operative movements have much in common. This chapter aims to examine the convergences and divergences between the two fields, highlighting what they can learn from each other and how practitioners and researchers in the two areas can better collaborate. Fair trade is an innovative approach to economic development that uses a market-driven approach to exploit the growing trend in ethical, or caused-based, consumption (Nicholls & Opal 2005). Fair Trade organizations aim to re-engineer the value chains between poor producers and artisans - typically in developing countries - and their wholesale buyers such that a greater proportion of the overall rents accrue to those who provide the inputs. Put simply, Fair Trade aims to ensure that the poorest actors in a supply chain benefit from more of the overall financial value creation as a development tool. Moreover, Fair Trade reconnects producers and consumers at the point of purchase such that consumption becomes a political – or, at least, life style – choice. This chapter is structured as follows. After this introduction, the second section describes the development of Fair Trade from its historical roots to the current organizational landscape and market organization. Next there is a discussion of several key issues and challenges that have emerged as Fair Trade has become increasingly institutionalized. Then, the fourth section explores the relationship between Fair Trade and the co-operative and mutual movements. Finally, conclusions serve to sum up the chapter. [less ▲]

Lehrer weisen ein erhöhtes Risiko auf, Stimmstörungen zu entwickeln. Sogar Lehramtsstudierende sind bereits zu etwa 20% betroffen, obwohl die stimmlichen Anforderungen während des Studiums noch gering ausfallen (vgl. Ettehad 2004). Nur unzureichend wurde bislang die Stimme von Lehrkräften im Vorbereitungsdienst (LiV) untersucht. Gleichwohl ist der Vorbereitungsdienst ein kritischer Zeitraum. LiV unterrichten etwa 12 Stunden pro Woche und stehen unter hohem Leistungsdruck. Dies kann sich potentiell negativ auf die Stimme auswirken. Ziel der Studie war es demnach, die Prävalenz und Art von Stimmstörungen bei Lehrkräften im Vorbereitungsdienst zu bestimmen. Weiterhin sollten Zusammenhänge zwischen subjektiven und objektiven stimmbezogenen Daten untersucht werden. 73 LiV nahmen an der Studie teil, die sich aus einem selbstkonzipierten Fragebogen und der Erhebung objektiver Daten zusammensetzt. Probanden, die im Fragebogen angaben, während des Vorbereitungsdienstes bereits zwei oder mehr Symptome einer Stimmstörung wahrgenommen zu haben, wurden als stimmgestört klassifiziert. Anhand objektiver Messungen wurden zudem die Variablen maximale Tonhaltedauer (THD), Jitter und Shimmer erhoben und mit den subjektiven Daten in Beziehung gesetzt. Bei 37% der Probanden ergaben sich Hinweise auf das Vorliegen einer Stimmstörung. Besonders häufig wurden die Symptome Rauigkeit, Räusperzwang oder Lautstärkeprobleme genannt. Es bestand kein signifikanter Zusammenhang zwischen den subjektiven und den objektiven Daten. Die Ergebnisse deuten darauf hin, dass angehende Lehrkräfte im Zeitraum des Vorbereitungsdienstes vermehrt zu Stimmproblemen neigen. Dies unterstreicht die Notwendigkeit von interventiven Maßnahmen, die bereits im Studium zum Tragen kommen sollten. [less ▲]

Kluyveromyces marxianus S-2-05 and Kluyveromyces lactis S-3-05 were recently isolated from a traditional French cheese, Tomme d'Orchies, and characterized here for their advantages using a different application perspective. First, we established their anti-Salmonella activity and downregulation of the virulence sopD gene of Salmonella enterica subsp. enterica serovar Typhimurium, mainly in the presence of K. marxianus S-2-05. In addition to their antagonism, these non-Saccharomyces yeasts were able to survive under conditions mimicking the gastrointestinal environment and to form biofilms on an abiotic device such as polystyrene. These strains also displayed highly hydrophilic cell wall surfaces properties and capacity for adhesion to intestinal Caco-2 cells, thus enhancing their potential as probiotic strains. [less ▲]

We introduce the concept of constant 2-labelling of a vertex-weighted graph and show how it can be used to obtain perfect weighted coverings. Roughly speaking, a constant 2-labelling of a vertex-weighted graph is a black and white colouring of its vertex set which preserves the sum of the weights of black vertices under some automorphisms. We study constant 2-labellings on four types of vertex-weighted cycles. Our results on cycles allow us to determine (r, a, b)-codes in Z^2 whenever |a−b|>4, r>1 and we give the precise values of a and b. This is a refinement of Axenovich’s theorem proved in 2003.

This paper proposes a novel control scheme for frequency support among asynchronous AC areas through HVDC grids. It is based on local controllers, each acting on a voltage source converter, using locally available measurements only, and supporting frequency of the adjacent AC area after a significant disturbance. The controller is combined with the existing DC voltage droop technique and is inspired of Model Predictive Control, taking into account various constraints. The coordination of the proposed control scheme with the existing secondary frequency control of an AC area is also discussed. Examples obtained from a test system with a five-terminal DC network connecting two asynchronous areas demonstrate the effectiveness of the proposed control scheme. [less ▲]

We propose a new method for automatic 3D multimodal registration based on anatomical landmark detection. Landmark detectors are learned independantly in the two imaging modalities using Extremely Randomized Trees and multi-resolution voxel windows. A least-squares fitting algorithm is then used for rigid registration based on the landmark positions as predicted by these detectors in the two imaging modalities. Experiments are carried out with this method on a dataset of pelvis CT and CBCT scans related to 45 patients. On this dataset, our fully automatic approach yields results very competitive with respect to a manually assisted state-of-the-art rigid registration algorithm. [less ▲]

Le projet STARECAPMED (STAtion of Reference and rEsearch on Change of local and global Anthropogenic Pressures on Mediterranean Ecosystems Drifts) a pour objectif (i) d’améliorer la compréhension du fonctionnement des différents écosystèmes marins côtiers présents en Méditerranée et (ii) de décrire l’influence des activités humaines sur les processus qui gouvernent ce fonctionnement. La baie de Calvi, par sa situation exceptionnelle, est un site de référence de la Directive Européenne Cadre sur l’Eau (DCE), du monitoring de l’eutrophisation et de la contamination par les éléments traces. La Station de recherches océanographiques STARESO, implantée dans la baie depuis près de 50 ans, possède un accès unique à la mer et de nombreuses facilités logistiques. Elle a développé au fil du temps une expertise scientifique reposant notamment sur l’acquisition de longues séries temporelles de données environnementales. Ensemble, Baie et Station s’intègrent en un site atelier dédié à l’évaluation de l’état de santé des écosystèmes marins côtiers de Méditerranée Nord-Occidentale. En particulier, différents indices et indicateurs y sont développés en collaboration avec de nombreux laboratoires partenaires. Ainsi, nous avons développé, d’une part, une version non destructive de l’indice PREI (Posidonia Rapid Easy Index) d’évaluation de la qualité des eaux côtières reposant sur le suivi des herbiers à Posidonia oceanica, et d’autre part, deux indices d’évaluation de l’impact des ancrages, puis testé   l’indice EBQI (Ecosystem Based Quality Index), une approche sur la diversité écologique. Les indices TEPI (Trace Element Pollution Index) et TESVI (Trace Element Spatial Variation Index) permettent d’évaluer la contamination par les éléments traces. Le BeMSI (BEnthic Methodology Simplification) est un nouvel indicateur de la qualité du milieu défini à partir de la composition des peuplements macrobenthiques des substrats meubles et plus généralement, l’indice LIMA traduit l’attrait paysager et la richesse patrimoniale du benthos méditerranéen entre 0 et –40 m. Quant à l’indice ICAR (Indice paysager CAulerpa Racemosa), il permet d’évaluer les niveaux de colonisation par l’algue invasive Caulerpa cylindracea. Enfin, une approche innovante reposant sur l’enregistrement des sons permet d’évaluer la qualité du milieu à partir d’un paysage acoustique sous-marin. En conclusion, le développement et l’application combinée de ces différents indices et indicateurs développés dans le cadre du programme pluridisciplinaire STARECAPMED fournissent une estimation globale des états du milieu côtier méditerranéen à différents niveaux d’organisation, depuis l’espèce jusqu’à l’écosystème. De plus, leur mise en œuvre dans ce même site atelier privilégié permet de les confronter, de les ajuster et de les intercalibrer pour à terme les proposer aux gestionnaires du milieu côtier.

This paper presents a novel approach, which identifies a buffer zone around a given study system and replaces the external system with an equivalent. The aim is to obtain a reduced system, which is suitable for assessment of long-term voltage and frequency dynamics in the study system. First, the proposed methodology ensures that all components, which are impacting the voltage profile of the study system, are included in the buffer zone. For that purpose, the propagation of reactive power changes from the boundary of the study system into the external system are used in a modified depth-first search algorithm to identify the buffer zone. Second, the external system is replaced with equivalents accounting for inertia and primary frequency control effects. The proposed method was successfully tested on a modified version of the ENTSO-E Dynamic Study Model. [less ▲]
