FACTORS INFLUENCING CAREER CHOICE AMONG NURSING STUDENTS
2018
Choosing a career is a complex and multi-factorial decision-making process that is based on several personal, situational and organizational factors. The purpose of this study is a literature review to determine factors influencing career choice among nursing students. The literature review displays that nursing students make their career decisions from a combination of personal interests in health care and their desire to help others. From the beginning of the studies students may have strong career preferences. Before they graduate and eventually decide about the future workplace, their career choices undergo several transitions. Career choices are influenced both by the students inclina…

Reducing salt and fat while maintaining taste: An approach using cross-modal sensory compensation
2014
Unbalanced diets with an overconsumption of fat, salt and sugars contribute to the development of pathologies. As a consequence, healthcare authorities advocate salt, fat and sugar reduction in food, but this often leads to less tasty products. Several strategies are currently investigated to design healthier food while maintaining taste and consumer liking. The strategy relying on cross-modal sensory compensation is being tested within the framework of the EU-TeRiFiQ research project. The main objective is to evaluate whether an optimisation texture, taste and aroma could help to maintain especially salt or fat perception in low-fat-salt food. Here we set out to examine whether a modificat…
L'intégration multisensorielle comme stratégie pour compenser la réduction en sodium et matière grasse dans les aliments
2015
In recent years;health authorities worldwide advise for a reduction of salt and fat in daily food consumption. However;foods with reduced salt and fat content are often not appreciated by consumers;Therefore;the formulation of low-salt-fat foods that maintain acceptability is a major concern in food research. In this thesis;the multi-sensory integration and release kinetics of flavor compounds were explored as strategies to compensate for salt and fat reduction in cheese products (model cheeses and real cheeses). The objective was to better understand the mechanisms leading to aroma and salt release during mastication and to evaluate how the matrix composition and structure influence salt a…
Cross-modal interactions between taste and smell: Odour-induced saltiness enhancement depends on salt level
2011
International audience; In recent years, health concerns related to salt have led to extensive research on low-salt foods. One major remaining issue is to reduce sodium content while still providing the salty fix, to maintain food appreciation, acceptance and choice. Using well-selected odours has been proposed to compensate for sodium chloride reduction in food, due to the cross-modal interactions between odour and taste. However, interactions between taste and odour, with regards to saltiness, remain poorly investigated. Moreover, although a few studies have assessed the influences of odour and sweet supra-threshold intensity on cross-modal interactions, none focused directly on how they …
Evolution de la perception sensorielle et des préférences alimentaires chez les personnes âgées : quel lien avec le statut nutritionnel ?
2012
Le processus de vieillissement, même lorsqu’il se déroule normalement, est associé à de nombreuses modifications d’ordre physiologiques (ralentissement du transit intestinal, du métabolisme basal, perte de dents, altérations des capacités chimiosensorielles), psychologiques (solitude, dépression, démence) et sociologiques (retraite, veuvage, déménagement…) susceptibles d’avoir un impact sur la prise alimentaire et le statut nutritionnel de la personne âgée. Au-delà de ces changements, l’apparition d’une dépendance pour l’alimentation, qui fait généralement suite à une perte d’autonomie de la personne (apparition d’une incapacité physique ou psychique, veuvage…), modifie en profondeur le rap…

Perception des molécules chimiosensorielles en mélange : impact du métabolisme périphérique
2015
The chemosensory system is highly sensitive and discriminant. To ensure these properties, rapid and effective mechanisms are necessary to eliminate chemosensory molecules reaching the perception interface. The xenobiotic metabolizing enzymes (XMEs) present in the peri-receptor space may participate to the clearance of molecules thus limiting chemosensory receptors saturation and promoting the termination of the signal. In our PhD thesis, the involvement of these enzymes in the detection of stimuli in mixture was assessed in two animal models allowing to test complementary aspects. In Drosophila melanogaster, a sensory exposure to caffeine causes a reversible alteration of the taste percepti…
