LE TERME « ÉCOTOURISME » ET SES QUASISYNONYMES DANS L’ESPACE MÉDIATIQUE FRANÇAIS

RÉSUMÉ. L’évolution du lexème écotourisme dans les quotidiens français (version informatisée) est le but de notre étude. Nous nous référons à Moirand (2007, p. 4) pour voir ce qui se passe « dans et par les médias » et à Charaudeau et Maingueneau (2002, p. 324) pour la mémoire des discours. Non seulement l’usage et les conditions sociales sont importants dans l’appréciation, la compréhension et la manière, dont sont présentées nos collocations, mais surtout le contexte dans lequel elles évoluent. Qu’il soit écologique, officiel (Ministère de l’Ecologie, du Développement durable et de l’Énergie) ou journalistique (slogan de propagande écologique), ces contextes nous paraissent essentiels pour une bonne compréhension. Notre but est l’analyse de ce phénomène. Le concept de écotourisme est riche en traits sémantiques, et malléable suivant les contextes et les visées médiatiques qu’on lui impose. Nous allons essayer d’approfondir ces singularités dans cet article. Mots-clés : collocation, contexte, discours, écotourisme, journaliste, manipulation, trait sémantique, visée discursive.  ABSTRACT. The evolution of the lexeme ecotourism in French newspapers (electronic version) is the aim of our study. We refer to Moirand (2007, p. 4) to see what happens "in and through the media" and Patrick Charaudeau et Maingueneau (2002, p. 324) for the memory of the speech. Not only the use and social conditions are important in the appreciation, understanding and speaking, which are presented our collocations, but especially the context in which they operate. It is environmentally friendly, official (Ministry of Ecology, Sustainable Development and Energy) or journalistic (ecological propaganda slogan), these contexts we consider essential for a proper understanding. Our ambition is to analyse this phenomenon. The concept of ecotourism is rich in semantic traits and malleable depending on the context and media referred imposed on it. We will try to deepen these singularities in this article. Keywords: collocation, context, discourse, ecotourism, journalist, manipulation, semantic trait, discursive aim

Colour Contrast Occurrence matrix: a vector and perceptual texture feature

International audienceTexture discrimination was the second more important task studied after colour perception and characterization.Nevertheless, few works explore the colour extension of these works and none for vectorial processing ofthis important visual information. In this work we propose a novel and vector processing for colour texturecharacterization, the color contrast occurrence matrix C2O. This new texture feature is based on the colourdierence assessment. To be link to the human perception, the colour dierence is expressed using a perceptualdistance expressed in CIELab and two angles characterizing the chromaticity and darker or lighter direction.Through this new attribute, we analyze the stability to changes in illumination, viewpoint and spectrum of thelight source in front of dierent texture image databases . Thanks to our construction, we avoid the main limit ofexisting texture features requiring an initial colour quantization or a binarization inside the texture construction.Keeping the small local contrast, we obtain a more accurate texture feature description explaining the obtainedresults. Then we carry out the construction of a features vector by occurrence quantization, keeping the initialideas of Julesz, Haralick and Ojala, for the classication purposes. The results show best correct classicationpercentages in databases that with important spatio-chromatic complexity as ALOT

Creating and sustaining a high-performing tennis culture

The coach is identified as a key actor in the development of a high-performing culture, in this case, tennis. We investigated how the participating tennis coaches on the International Tennis Federation/Olympic Solidarity Tennis program in Spain made an impact within their national organizations, by developing and implementing a coach-created high-performing environment. We collected data using both interview and survey. Our findings from the survey indicated that the participating coaches found the program to be very helpful to their practice, especially long term tennis development, structure and organization of effective tennis programs and appropriate training methods. Analysis of the interviews revealed three main themes: 1) high-performing environment 2) deliberate focus on growth and development; 3) obstacles to creating a tennis culture. We discuss the difficulties associated with transferring a successful development programme to a different environment and conclude with some key points for implementation

Reflections on 20 years of the International Tennis Federation and Olympic Solidarity High-Performance Coach Education Scholarship Programme:Implications for sports coach development

This paper reflects on the impact of the International Tennis Federation and Olympic Solidarity High-Performance Coach Education Scholarship Programme over the last 20 years. Coach education and development has been identified as key to the advancement of sport performance. This programme has been investigated using an online survey and followed up with semi-structured interviews, with participants and coach developers. Results from the survey suggested that the programme was well received by the tennis coaches and integral to their ongoing development plus the growth of tennis performance in their countries. Follow-up interviews revealed the three key themes of supportive environment, lifechanging experience and level of challenge contributed to the effectiveness of this programme and the subsequent development of tennis performance. This concludes with some recommendations for coach development programmes

Bridging the Semantic Gap in Multimedia Information Retrieval: Top-down and Bottom-up approaches

Semantic representation of multimedia information is vital for enabling the kind of multimedia search capabilities that professional searchers require. Manual annotation is often not possible because of the shear scale of the multimedia information that needs indexing. This paper explores the ways in which we are using both top-down, ontologically driven approaches and bottom-up, automatic-annotation approaches to provide retrieval facilities to users. We also discuss many of the current techniques that we are investigating to combine these top-down and bottom-up approaches

Metformin as a Therapeutic Target in Endometrial Cancers.

Endometrial cancer is the most common gynecologic malignancy in developed countries. Its increasing incidence is thought to be related in part to the rise of metabolic syndrome, which has been shown to be a risk factor for the development of hyperestrogenic and hyperinsulinemic states. This has consequently lead to an increase in other hormone-responsive cancers as well e.g., breast and ovarian cancer. The correlation between obesity, hyperglycemia, and endometrial cancer has highlighted the important role of metabolism in cancer establishment and persistence. Tumor-mediated reprogramming of the microenvironment and macroenvironment can range from induction of cytokines and growth factors to stimulation of surrounding stromal cells to produce energy-rich catabolites, fueling the growth, and survival of cancer cells. Such mechanisms raise the prospect of the metabolic microenvironment itself as a viable target for treatment of malignancies. Metformin is a biguanide drug that is a first-line treatment for type 2 diabetes that has beneficial effects on various markers of the metabolic syndrome. Many studies suggest that metformin shows potential as an adjuvant treatment for uterine and other cancers. Here, we review the evidence for metformin as a treatment for cancers of the endometrium. We discuss the available clinical data and the molecular mechanisms by which it may exert its effects, with a focus on how it may alter the tumor microenvironment. The pleiotropic effects of metformin on cellular energy production and usage as well as intercellular and hormone-based interactions make it a promising candidate for reprogramming of the cancer ecosystem. This, along with other treatments aimed at targeting tumor metabolic pathways, may lead to novel treatment strategies for endometrial cancer
