Antiproliferative activity of green, black tea and olive leaves polyphenols subjected to biosorption and in vitro gastrointestinal digestion in Caco-…

2020

Olive (Olea europaea L.) leaves and tea (Camellia sinensis) are rich sources of bioactive compounds, especially polyphenols. Our previous studies have evidenced the potential use of Saccharomyces cerevisiae as a natural delivery system for these antioxidants and a means to improve their bioaccessibility in the human gut. In the present work, the antiproliferative effect of green tea (GT), black tea (BT) and olive leaves (OL) infusions and suspensions of S. cerevisiae were evaluated, for the first time, in human colon cancer cells (Caco-2) after biosorption and in vitro gastrointestinal digestion. The bioaccessible fractions (BF) were not overtly cytotoxic, not affecting cell viability. ROS …

Rachats d'actions et augmentation de capital : une analyse de leur combinaison appliquée au marché français

2013

Noting that over 22% of capital increases thrown at the French financial market are made when a share repurchase program is in progress, we propose an original study of the combination of the two operations. From 50 operations for the period 1999-2006, we test if the buybacks "prepare" the market before launching the capital increase or means to change the distribution of voting rights. Our results infirm these two hypotheses and confirm rather the proposition of a fortuitous concomitance.

Activisme et proxy fight. Quand les actionnaires déclarent la guerre au management

2009

Les attentes des actionnaires minoritaires sont relativement heterogenes : les salaries ou les fournisseurs qui detiennent des actions ne sont pas uniquement preoccupes par les dividendes ou les plus-values, contrairement aux actionnaires patrimoniaux. Ces derniers, qui peuvent etre insatisfaits par certaines decisions strategiques ou operationnelles prises par les dirigeants, ont la possibilite d’agir pour proteger leurs interets, en s’engageant notamment dans une bataille de procuration. Dans cet article, les auteurs insistent sur les principales difficultes rencontrees par les actionnaires contestataires lors de ces batailles, sur les facteurs cles de succes, ainsi que sur les consequenc…

Le déploiement d'un pilotage stratégique des coûts dans les services informatiques de deux groupes internationaux : perspective instrumentale et anal…

2011

This article analyses the strategic cost management stream with an instrumental point of view and two case studies. We try to show in what extend the Activity-based Costing developments could be included in a strategic approach of the management accounting and to test if the ABC is a relevant tool to drive the strategy. The first part synthesizes the strategic cost management developments which try to improve the Activity-based Costing method. In the first part, we describe them using the Strategic Management Accounting stream, with a link with cost management and ABC. The second part exposes a taxonomy of the reasons why using the ABC method. In a third part, we confront our developments t…

Les managers de proximité face aux compétences : une approche située

2013

Line managers and qualifications: a situated approachQualifications have seldom been analyzed as closely as possible to the operational level, a possibility of special interest to line managers and a genuine issue for research and management. Supervisors are continually in the position of making judgments about the qualifications of the persons and work teams whose activities they organize to reach the objectives set. Starting from observations conducted in several situations at the workplace, the concept of a “qualification oriented toward the situation” is drawn up around three dimensions : situation, qualification and performance. Its usefulness is empirically illustrated in the case of …

To this purpose we conduct and present the results of a longitudinal controlled field experiment over 18 BPR projects lasting 3 months and involving 18 teams comprising 71 first-year MBA students. The main contribution of this study is twofold. First, we explicitly consider and measure the core construct of groupthink phenomenon: that is, GTB. Existing organizational behavior literature has, …

Analyse historique du concept de performance en Chine. Un regard occidental

2015

A historical analysis of the concept of Performance in China. A Western lectureWe base our work on an historical study of the concept of performance in China. We postulate from a literature review that organizations and their managers are strongly influenced by cultural and institutional determinants. As a result, we present these determinants that enable us to justify several hypotheses about Chinese managers’ behaviors. In this article, we show the disappearance of Confucian values behind a combination of pragmatism, interpersonal relations and influence networks.

Effects of stress on chewing and food intake in patients with anorexia nervosa

2021

OBJECTIVE The present study investigates the impact of psychosocial stress on chewing and eating behavior in patients with anorexia nervosa (PAN ). METHOD The eating and chewing behavior of PAN were examined in a standardized setting by means of a chewing sensor. These procedures encompassed n = 19 PAN , age, and gender matched to n = 19 healthy controls (HC). Food intake and chewing frequency were assessed in two experimental conditions: rest versus stress (via Trier Social Stress Test). To verify stress induction, two appraisal scales were employed. In addition, chronic stress, psychological distress and eating disorder symptoms were assessed. RESULTS In terms of food intake and chewing f…

The Psychological Foundations of Management in Family Firms: Emotions, Memories, and Experiences

2021

Exploring the psychological foundations of management in family firms is necessary to understand why they formulate and implement strategies differently from nonfamily firms, and why and how family firm behavior varies across different family firms. Picone et al. (2021. The psychological foundations of management in family firms: Values, biases, and heuristics. Family Business Review, 34(1), 12-32) have proposed a conceptual framework for the psychological foundations of management in family business, examining how the values, biases, and heuristics of family firm members affect strategic decision-making and family firm outcomes. Drawing on this framework, we examine emotions, memories, an…
