Work is What I Want

slinko, nataliya 10 May 2013 (has links)
This thesis is written as an essay, which considers sculpture outside of its definition as art object. Having as its goal finding an intrinsic definition of sculpture, the essay sets on a short journey meandering between ideas, historic precedents, and anecdotes. Among some of the discussed thing are: necessity, labor, leisure, Olduvai chopping stone tool, making, human hand, brain, body, pineal gland, third eye, speculation, materiality, Dixie cup, objecthood, sign, imagination, ENIAC, immateriality, myth, labor, leisure, storytelling, alien, alienation, destruction, creativity, genius, death, weed. The essay concludes that sculpture does not need a definition.

Codes transcriptionnels et expression du gène du récepteur de la GnRH au cours du développement et chez l’adulte / Transcriptionnal codes and expression of the GnRH receptor gene during development and in adult

Schang, Anne-Laure 01 June 2011 (has links)
Le récepteur hypophysaire de la GnRH (RGnRH) joue un rôle crucial dans le contrôle de la fonctionde reproduction. Dans le promoteur distal du Rgnrh, j’ai caractérisé un élément de réponsebifonctionnel répondant aux protéines LIM à homéodomaine ISL1/LHX3 et à GATA2. D’autre part,deux motifs TAAT situés dans la région plus proximale confèrent à ce gène la capacité de répondreaux facteurs Paired-like PROP1 et OTX2. Tous ces facteurs, exprimés précocement au cours del’ontogenèse hypophysaire, pourraient participer à l’émergence de l’expression du Rgnrh. Hors del’hypophyse, j’ai découvert que le Rgnrh est exprimé au cours du développement postnatal dansl’hippocampe de rat, où il module la plasticité synaptique. Par ailleurs, j’ai identifié deux nouveauxsites d’expression, la rétine et la glande pinéale. Ces résultats mettent en lumière l’importancefonctionnelle de ce récepteur et de son ligand et les rôles multiples qu’il ont acquis au cours del’évolution des Vertébrés. / In the pituitary, the GnRH receptor (GnRHR) plays a crucial role in the neuroendocrine control ofreproductive function. Within the distal region of the Gnrhr promoter, I have characterized abifunctional response element modulated by the LIM homeodomain proteins ISL1/LHX3 and byGATA2. Besides, in the proximal region of the promoter, two TAAT motifs conferred response toPaired-like factors PROP1 and OTX2. All these factors are expressed during pituitary ontogenesis andcould participate in the onset and regulation of Gnrhr expression. Outside of the pituitary, I havediscovered that the Gnrhr was expressed during postnatal development in the rat hippocampus, whereit modulated synaptic plasticity. Furthermore, I have identified two novel sites of Gnrhr expression, theretina and the pineal gland. Altogether, these data highlight the functional importance of this receptorand its ligand as well as the multiple roles they have acquired during vertebrate evolution.
