Antropólogo Social / La presente investigación realiza una lectura desde la teoría del don de las dinámicas de intercambio intergeneracional entre viejos y viejas y sus hijos e hijas adultos/as1 en la ciudad de Santiago de Chile. Teniendo en cuenta el proceso de envejecimiento poblacional que vive la sociedad chilena y las transformaciones que vive actualmente la familia como forma de organización social, en la cual cada vez más generaciones conviven durante más tiempo, se estudia desde una perspectiva cualitativa y centrada en los discursos la manera en que los viejos participan en su grupo familiar a través de las relaciones de intercambio de favores y cuidados en la vida cotidiana. La participación en estos intercambios habla de una cierta manera de asumir la reciprocidad en la familia, en este caso, en relación a los intercambios con la generación de los hijos. Primero, se abordan hechos biográficos de los padres con el motivo de contextualizar las lógicas de intercambio en la vejez y es posible ver cómo ciertos hechos biográficos asociados a la vejez, como la viudez, la jubilación y la llegada de los nietos intervienen de diferente forma en la capacidad de los padres viejos de mantener una actitud donadora en el seno de la familia. Los cambios asociados a la vejez producen en los hijos un reconocimiento de la existencia de nuevas necesidades en sus padres. Así, comienza una nueva etapa de intercambios de favores y cuidados entre estas dos generaciones marcada por un interés de no perder la capacidad donadora por parte de los padres, teniendo la autonomía y la libertad frente a los hijos como valores que orientan su participación, especialmente en los casos en los que existen favores financieros de por medio

This work illustrates the spatial nature of Don DeLillo's writing. Through a reading of his work a network of societal spaces repeatedly occur and are utilised as locations within which to raise questions of the relationship between identity and mass society. The spaces that predominate produce the topography of his work. A network begins to develop, a series of nodal points joined by a connective tissue of pathways through which the discussion of society and identity pass. By focusing on both the nodal points themselves and the pathways that connect them the roles of motion, control and a potential counter-narrative appear. The individual spaces that DeLillo chooses as locations in his novels are relevant. Their placing in society, their means of construction and the materials of which they are constituted all illustrate the form of society which created them. In turn these spaces are observed to shape the characters that pass through them, in the process further expanding the network of societal associations. The particular spatial forms that DeLillo focuses on reflect a transitional impulse, a desire for motion and speed rooted in anti-historicism. The suburb, the motel, and the highway are all born of the period which followed the Second World War which had a profound sociological, psychological and technological impact on society. The need to face the future, reject the past and repress the traumatic experiences of war led an experience of space and society which is transitional. The spaces are selected for their association with anxiety, trauma, nostalgia and consumption. The duality of these spaces epitomises the complexities of modern social identity. Due to the reflexive nature of transitionality cultural shifts impact upon its form, altering the way in which it appears and functions. The alleyway influences the development of the highway, the motel influences the development of the suburb, and the railway station affects the airport. The airport is an example of the manner in which technological advance change the appearance of these spaces but the themes and issues that are explored in them reflect consistent interests. Similarly, moments of great social import such as the Kennedy assassination and the attacks of 9/11 leave traces on these transitional spaces.

La Nachbarschaft ou « institution de voisinage » est une forme d’entraide instituée pratiquée en Transylvanie/Roumanie depuis des siècles. Elle se réfère à une forme spécifique et organisée de relations de voisinage au sein des différents groupes ethniques roumain, tsigane, saxon ou hongrois. L’évolution de la cohabitation interethnique, la définition et les revendications des uns et des autres sont intimement liées à l’articulation des relations économiques, sociales, de pouvoir et d’autonomie à travers le temps. Les relations qualifiées aujourd’hui d’« interethniques » s’inscrivent dans un lent processus de cohabitation, à différentes échelles, dont les catégories ont perduré mais ont changé de signification au cours des siècles. Quelle est la place de cette institution vieille de plusieurs siècles dans la Roumanie actuelle, dite « en transition » depuis la chute du régime communiste? Les institutions de voisinage continuent-elles à combler un certain vide laissé par l’Etat ? Alors que la construction de la « société civile », terme clé de la littérature scientifique sur la transition des pays de l’Est, est un des processus jugés vitaux dans les années suivant la chute du mur, l’institution de voisinage n’a pas arrêté d’investir cet échelon de vie collective. Comment investit-elle cet espace d’échange entre unités domestiques, sur quoi est fondé cet échange ? Enfin, quelles sont les dynamiques qui l’animent et qui conditionnent sa transmission ?

Fusarium head blight (FHB), caused mainly by Fusarium graminearum, is one of the most destructive global diseases of small cereal grains worldwide. The most devastating effect of this disease is the deposition of mycotoxins in the grain. Deoxynivalenol (DON) and its analogs 3-ADON, 15-ADON and NIV are the major mycotoxins produced by the fungus. The chemotype, 15-ADON is more prevalent in North America, but recently a chemotypic shift has been observed. The rapid emergence of the 3-ADON chemotype over the traditional 15-ADON chemotype is a major concern in North America. The studies in this thesis were focused on understanding the behaviour of the 3-ADON and 15-ADON chemotypes and the possible reasons for the rapid chemotypic shift.
