The role of maternal effects in host-parasite interactions: examination of the development of the immune defense in a colonial seabird, the black-leg…
2004
One of the main aims of evolutionary biology is to understand the mechanisms responsible for the phenotypic variation on which natural selection can act. Maternal effects occur when a mother's phenotype or her environment influence her offspring's phenotype. Despite the importance of such effects for the ecology of host-parasite interactions, their role has been relatively neglected to date. In this thesis, we examined how mothers influence the immune defense of their young in an environment that varies in space and time. This work has primarily focused on a colonial seabird, the black-legged kittiwake (Rissa tridactyla). Using this model, we have first shown that specific maternal antibodi…
Negative responses to strategic innovation, a case study of record labels facing streaming
2021
Record labels are organizations in charge of phonographic production at the interface between musicians and the audience. Since the arrival of digital technologies such as the mp3 and the Internet, record labels have had to adapt to several changes: wider distribution channels, dematerialized competitors, customers’ demands for free music, more ephemeral cooperation. Specifically, streaming platforms like Spotify brought a major change known as a strategic innovation. A strategic innovation is a strong change that overturns all previously established values in the sector (renewal of values attached to the product, values attached to the customer relationship and power relations). However, f…
Réflexion sur le lieu de consommation culturelle. Une application au cas des musiques actuelles
2004
The following study sheds light on the importance of managing a forsaken element of cultural experience : the place. Because of the weakness of the works relating to this element in the cultural domain, we use the works in distribution. Several competing theories are considered to conceptualize the cultural place: the own characteristics of the place, the behaviors and the “responses to the place”. The last track having our preference, an exploratory study will come in support to define the differents dimensions that compose this “response to the place”. Pop music will constitute our field of application.

The appearance of several diseases, such as cancer, diabetes, high blood pressure and spread of infections mutagenic virus type can be linked to the quality and lifestyle that we lead today. Indeed, several studies on the factors triggering these so-called "morbid" long-or short-term illnesses are related to stress and quality of food consumed, whether of plant and animal origin. These diseases are becoming a common occurrence, they affect different races and all classes of society. According ethnobotanical research, naturally occurring substances, allowed civilizations to survive deadly diseases. For example, we thus find references to periods of malarial fever in China and one of the symp…

La formation du comportement de plainte chez le consommateur: recherche exploratoire chez des usagers de restaurants
2008
La investigación que se presenta aborda el proceso de formación del comportamiento de queja del consumidor. El objetivo general es profundizar en la naturaleza de este tipo de respuesta a la insatisfacción, describiendo su formación a partir de la contribución de un conjunto de variables investigadas en la literatura. Partiendo de que el comportamiento de queja agrupa tres tipos de respuestas (de queja, a terceras partes y privadas), analizamos el efecto que tiene el nivel de insatisfacción, la probabilidad de éxito de la queja, la importancia de la situación y las actitudes hacia la queja. Las relaciones causales estudiadas entre estos determinantes y los comportamientos de queja han permi…
Le processus de choix alimentaire et ses déterminants : vers une prise en compte des caractéristiques psychologiques du consommateur
2006
This thesis aims to explore new research opportunities in the food field, proposing to explicitly include psychological factors as potential determinants of food choice process. It notes the consequences of the central role of pleasure in the mechanisms of ingestion, and the specific role of taste: the highly emotional nature of food consumption leads then to retain experiential approach and more specifically sensory marketing as a framework. The issue of research aims to investigate how sensory stimuli and the information associated with the product combine to influence, in a differentiated manner depending on the individual, consumption behavior.Methodologically, the research combines con…
