L'expression d'opinions personnelles dans les interactions en classe : (dis)continuités dans la gestion des positionnements épistémiques entre l'école obligatoire et postobligatoire

Degoumois, Virginie ; Pekarek Doehler, Simona (Dir.) ; Gagnon, Roxane (Codir.) ; Markee, Numa (Codir.) ; Melander, Helen (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2017.

Using conversational analysis, the current research intends to document the expression of personal opinions in French L1 classrooms during discussion activities promoting oral expression. This study is based on audiovisual data from two different grades of obligatory and post-obligatory schooling (referred to as secondary 1 and 2) in French-speaking Switzerland. The expression of opinion is...

Cell mechanics in flow : algorithms and applications

Lykov, Kirill ; Pivkin, Igor V. (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2017 ; 2017INFO008.

The computer simulations are pervasively used to improve the knowledge about biophysical phenomena and to quantify effects which are difficult to study experimentally. Generally, the numerical methods and models are desired to be as accurate as possible on the chosen length and time scales, but, at the same time, affordable in terms of computations. Until recently, the cell mechanics and blood...

Calix[n]tetrahydrofuran[4-n]pyrrolidines : optimized synthesis via hydrogenation of calix[n]furan[4-n]pyrroles, conformational study and preliminary work on their transition metal complexes

Maupillier, William ; Neier, Reinhard (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2016.

An hydrogenation method for the reduction of the easy accessible meso-octaalkylporphirinogen (calix[4]pyrrole) has previously been reported in our group. This “standard method” leads to an unsatisfactory conversion to the saturated analogue, calix[4]pyrrolidine (18% yield determined by GC). However using large excess of the catalyst leads to total conversion. In order to study...

A molecular approach to microeukaryotic diversity, ecology and biogeography associated with Sphagnum mosses

Singer, David ; Lara, Enrique (Dir.) ; Mitchell, Edward AD (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2017.

Despite the fact that free-living microeukaryotes compose the major part of Earth’s biodiversity and play numerous essential roles in ecosystems, knowledge on their true diversity, ecology and their global patterns of distribution remain limited. In this sense, the objectives of this thesis are 1) to increase the knowledge on the diversity of microeukaryotes 2) characterize the ecological...

Évaluation métrologique de l'étalon primaire de fréquence FoCS-2 avec une incertitude de quelques 10-15

Jallageas, Antoine ; Südmeyer, Thomas (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2017.

This work focusses on the study and the metrological evaluation of the FoCS-2 primary frequency standard. This atomic clock, one of a kind, uses a continuous beam of cold cesium atoms. Following 20 years of development in the Observatory of Neuchâtel and the Time and Frequency Laboratory of the University of Neuchâtel, FoCS-2 is now located in the federal institute of metrology METAS in Bern....

Une génération d'intellectuels catholiques dans la Pologne de l'Entre-Deux-Guerres : "l'Oeuvre de Laski" et son milieu

Latała, Renata ; Python, Francis (Dir.)

Thèse de doctorat : Université de Fribourg, 2013.

Avec une évocation du passage à l'Université de Fribourg de Władisław Korniłowicz (p. 58-72).

Feedback im Kontext von Lehrbetrieben

Furlan, Nicole ; Gurtner, Jean-Luc (Dir.)

Thèse de doctorat : Université de Fribourg, 2017.

Ein ausreichendes Angebot von Feedbacks durch erfahrene Personen und eine hochwertige Gestaltung von Feedbacks werden in der Lernforschung als zentral für Lernprozesse von Lernenden hervorgehoben. Nach einer theoretischen Auseinandersetzung zu Feedbacks im Kontext von Lehrbe-trieben und der Zusammenfassung des Forschungsstandes, werden in dieser Forschungsarbeit Er-gebnisse zur Frage...

Theory and applications of bijective barycentric mappings

Schneider, Teseo ; Hormann, Kai (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2017 ; 2017INFO007.

Barycentric coordinates provide a convenient way to represent a point inside a triangle as a convex combination of the triangle's vertices, and to linearly interpolate data given at these vertices. Due to their favourable properties, they are commonly applied in geometric modelling, finite element methods, computer graphics, and many other fields. In some of these applications it is desirable...
