Many neurons and axons are eliminated during the development of the nervous system. These cells and their connections are thus overproduced, and the organism has to destroy the surplus in order to function correctly. A major mechanism responsible for this elimination appears to be competition between cells for a substance necessary for their survival. To examine this hypothesis, the present work...

Reading literacy texts in hypermedial applications : a semiotic-hermeneutic approach to new media for literary studies = Leggere testi letterari in applicazioni ipermediali : un approccio semiotico-ermeneutico ai nuovi media per gli studi letterari.

Mazzali-Lurati, Sabrina ; Schulz, Peter (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2003 ; 2003COM004.

Ranging between humanities and technological studies, this dissertation aims at clarifying what happens when literary texts we are used to read in a “book form” are transposed in hypertexts and hypermedia, namely which are the effects of this transposition on the act of reading the literary text. The work is based on an interdisciplinary approach, comprising a semiotic-hermeneutic perspective...

Thèse de doctorat : Università della Svizzera italiana, 2005 ; 2005COM001.

This thesis aims to discover the motivations leading a company to communicate through humour. Humour is seen as a language in order to understand where, how and when it is usefully used.

Le Paléogène des synclinaux du Jura et de la bordure sud-rhénane : paléontologie (Ostracodes), paléoécologie, biostratigraphie et paléogéographie

Picot, Laurent ; Berger, Jean-Pierre (Dir.)

Thèse de doctorat : Université de Fribourg, 2002 ; no 1375.

In the distal part of the Swiss Molassic basin, a typical foreland basin, the Jura Molasse is trapped within different synclines. This study focused on the paleogene deposits present in these synclines and as well as in the south border of the Graben. All formations mentionned in the literature were identified and a hiearchy was established. Each formation was defined and fixed on the...

Sédimentologie, stratigraphie séquentielle et cyclostratigraphie du Kimméridgien du Jura suisse et du Bassin vocontien (France) : relations plate-forme - bassin et facteurs déterminants

Colombié, Claude ; Strasser, Andreas (Dir.)

Thèse de doctorat : Université de Fribourg, 2002 ; no 1380.

A detailed sedimentological, sequential and cyclostratigraphic interpretation of the Kimmeridgian in the Swiss Jura defines the principal factors which control the different stages in the development of a shallow-water carbonate platform. A comparative study in the Vocontian Basin reveals their impact on hemipelagic and pelagic sedimentation. The sedimentary facies of three platform sections –...

Les géographies de la grandeur et la transition du système de production alimentaire suisse

Gigon, Nathalie ; Ruegg, Jean (Dir.)

Thèse de doctorat : Université de Fribourg, 1999 ; no 1281.

Economy and territory are interdependent elements of the regional development process. These two components, indissociable from a region’s economic development, are taken into account in recent theories of regional science. Yet, after closer examination, the operational concepts developed in these theories prove to be limited. Although territory is perceived as having multiple aspects,...
