Depuis sa création en 1927, l’Assemblée permanente des chambres d’agriculture a changé plusieurs fois de rôle et de composition sociale. Son histoire commence alors que les unions de syndicats agricoles sont sur le point de fêter leur cinquantième anniversaire et l’APCA débute donc une longue quête pour devenir un rouage entre les organisations professionnelles agricoles et l’État. Institution exclusivement consultative dans les années 1930, l’assemblée devient progressivement une pièce de la politique de développement agricole, autour des années 1960 et 1970, en mettant à disposition des chambres départementales d’agriculture un support technique et administratif, et en développant des compétences en matière d’expertise, ainsi qu’une politique éditoriale. Les méthodes prosopographique et micro-historique permettent de démontrer que ce processus est l’œuvre de longue haleine de certains dirigeants syndicaux agricoles et de leurs directeurs, nés au début du 20e siècle, comme il est le produit d’adaptations lentes de tous les acteurs impliqués : un système de bases de données relationnelles rend possible le suivi des 8000 membres et des 500 présidents de chambre d’agriculture tout au long de leurs trajectoires ainsi que leur localisation dans la nébuleuse des réseaux professionnels et politiques. De la Troisième République à la Corporation paysanne de Vichy, de la Libération aux « Trente glorieuses », cette histoire peut également être lue comme le biais par lequel l’agrarisme a continué d’exister tandis que le paradigme productiviste s’impose. / Since its founding in 1927, the Permanent Assembly of Chambers of Agriculture (Assemblée permanente des chambres d’agriculture, APCA) changed several times its role and social profile. Its history begins while the farmers unions are almost celebrating their fiftieth anniversary. The APCA then starts a long quest to set itself as an intermediary between the agricultural professional organizations and State structures. Although this institution is exclusively a consultative one in the 1930’s, it progressively tends to become a protagonist of the agricultural development policy in the 1960’s-1970’s, offering technical and administrative support to the local chambers of agriculture, and developing a public advisory capacity as well as its own publishing policy. Prosopographical and micro-historical methods allow us to demonstrate that this process of institutionalization has been the long-term task of some farmers leaders and their managers, men born at the beginning of the twentieth century, and that its success is the result of slow adapations of all the players involved. A relational database system allows us to follow the social trajectories and to localize in the nebula of professional and political networks some 8.000 members of the chambers of agriculture of this period, as well as their 500 presidents. From the Third Republic to the Peasant corporation of the Vichy régime, and then from the Liberation in 1944-1945 to the agricultural modernization of the “Trente glorieuses”, this history is also a way to enlight how agrarism as a pattern of control could endure while productivism as a new paradigm was asserting itself.

The threshold energy for the reaction Br⁸¹ (p,n)Kr⁸¹ was measured and found to be 1.133±.020 Mev. The threshold for Cd¹¹⁶(p,n)ln¹¹⁶ was searched for up to 1.8 Mev but was not found. The density of cosmic neutrons was measured at the earth's surface. It was found to be 4.2±.7x10⁻⁹ n/cm³ over land with 66% in thermal equilibrium. Over the sea, this density was 3.72±.98x10⁻⁹ n/cm³ with 64% in the thermal peak. The earth's albedo or reflectivity to neutrons impinging on it from the atmosphere was estimated to be .22. / Science, Faculty of / Physics and Astronomy, Department of / Graduate

Experiments are described on the possibility of developing a gas luminescence chamber for the observation of particle tracks. A brief review of devices currently available for obtaining ionizing particle tracks, particularly those capable of time resolutions in the microsecond region, is included. Attempts were made to detect scintillations in several gas and vapour mixtures. For some gas mixtures the possibility of using ionizing radiation to initiate a light producing chain reaction was investigated. These experiments were performed in the temperature range from 25 to 220° centigrade. Results obtained were not of such a nature to encourage further work towards the development of a gas luminescence chamber. As a background of non-radiation induced photon emission was observed for several reactions, it is possible that the methods employed in the experiment may be adopted to measure the onset and rate of some chemical reactions. / Science, Faculty of / Physics and Astronomy, Department of / Graduate

The thesis is an exploratory study of the gap between accounting research and financial reporting practices. The fundamental issue is that comprehensive accounting theories (CATs) have been largely disregarded in the formation of financial reporting practices. To understand why this should be so, the thesis studies continuously contemporary accounting (COCOA), the CAT associated with the Australian scholar Raymond John Chambers. The thesis adopts a hyperbolic reading of actor-network theory (ANT), which treats ANT on its own terms rather than diluting it by reference to other interpretive approaches. The thesis uses a single case-study approach that traces how Chambers developed what was to become COCOA throughout his life. Archival data and interviews, as well as primary and secondary literature, inform the empirical narrative. The narrative focuses on six distinct episodes: the publication of Chambers' first academic article in 1955, the debate and events that followed this article, attempts to influence financial reporting practices in the US in the 1960s, the publication of Chambers' most comprehensive statement on COCOA in 1966, further attempts to influence financial reporting practices in the US, UK, and Australia in the 1970s, and three instances where financial statements were prepared in accordance with COCOA in the 1970s. Through the empirical narrative, the thesis contributes to knowledge about the gap between accounting research and financial reporting practices by studying an actual CAT and the attempts of its proponent to change conventional thinking. What emerges is a nuanced narrative about COCOA filled with various actors, not normally associated with accounting research, that nonetheless turn out to be vital to the success of COCOA.
