Book Description
CETTE THESE CHERCHE A REPONDRE A DEUX INTERROGATIONS : PEUT-ON TROUVER UNE JUSTIFICATION A L'HYPOTHESE, COURANTE DANS LA LITTERATURE, SELON LAQUELLE LE PRIX DE L'ENERGIE SUIVRAIT UN MOUVEMENT BROWNIEN GEOMETRIQUE ? QUELLES SONT LES CONSEQUENCES DE CETTE HYPOTHESE SUR L'INVESTISSEMENT OPTIMAL D'UNE ENTREPRISE ET SUR LA CROISSANCE ? DANS LA PREMIERE PARTIE, UN MODELE THEORIQUE D'UTILISATION OPTIMALE D'UNE RESSOURCE NON RENOUVELABLE COMPORTANT UNE FONCTION D'UTILITE RECURSIVE PERMET DE CONCLURE D'UNE PART QUE LA VALEUR DE L'ELASTICITE DE SUBSTITUTION INTERTEMPORELLE RELATIVEMENT A L'UNITE ET DETERMINANTE POUR LE SENS DE L'EFFET DE L'INCERTITUDE (SUR LE STOCK DE RESSOURCE ET SUR LA PRODUCTIVITE) SUR L'EXTRACTION OPTIMALE ET D'AUTRE PART QUE LE PRIX D'UNE TELLE RESSOURCE SUIT UN MOUVEMENT BROWNIEN GEOMETRIQUE DES LORS QUE LA PRODUCTIVITE SUIT ELLE-MEME UN MOUVEMENT BROWNIEN GEOMETRIQUE. LA DEUXIEME PARTIE ETUDIE LA TRANSMISSION DE L'INCERTITUDE SUR LE PRIX DE L'ENERGIE A LA DECISION IRREVERSIBLE D'INVESTISSEMENT D'UN ENTREPRENEUR PRODUISANT A PARTIR DE CAPITAL ET D'ENERGIE. ON MONTRE QU'EN CONCURRENCE MONOPOLISTIQUE, DEUX EFFETS ANTAGONISTES DE CONVEXITE ET D'IRREVERSIBILITE COEXISTENTMAIS QUE CE DERNIER L'EMPORTE TOUJOURS. SI UN COUT FIXE QUE L'ENTREPRISE DOIT PAYER CHAQUE FOIS QU'ELLE INVESTIT EST INTRODUIT DANS LE MODELE, IL N'INCITE L'ENTREPRISE A DETENIR PLUS DE CAPITAL QU'EN HORIZON FINI. CEPENDANT, EN HORIZON INFINI, LA TAILLE DE L'INVESTISSEMENT NE DEPEND PAS DE CELLE DE L'INCERTITUDE ET L'ENTREPRENEUR CONNAIT A L'AVANCE TOUTE LA CHRONIQUE DE SES INVESTISSEMENT FUTURS.DANS LE CADRE D'EQUILIBRE GENERAL CONSIDERE DANS LA TROISIEME PARTIE, L'INCERTITUDE SUR LE PRIX DE L'ENERGIE SE TRANSMET PAR LE CANAL DE L'IRREVERSIBILITE MAIS AUSSI PAR CELUI DES PREFERENCES DES AGENTS. ON MONTRE QUE SOUS LA MEME HYPOTHESE D'ELASTICITE DE SUBSTITUTION INTERTEMPORELLE SUPERIEURE A L'UNITE, L'INCERTITUDE FAVORISE L'INVESTISSEMENT IRREVERSIBLE ET REDUIT L'INVESTISSEMENT REVERSIBLE.

Book Description
Iodine is a naturally occurring element and inorganic iodines found in the ocean accumulate in fish, shellfish and seaweed. Industrially iodine is used in many applications including the manufacture of inks, dyes, photographic agents and in water-purification. In the health-care industry, iodine is widely used as a disinfectant/biocide and in the production of soaps, bandages, and medicines. Iodine is also included as a salt in some countries to provide dietary supplementation. This Concise International Chemical Assessment Document (CICAD) evaluates the scientific literature on the health aspects of iodine and inorganic iodides. Its focus is on the health effects from environmental exposures beyond those associated with the diet and nutritional supplementation. Radioactive iodine isotopes are regarded as outside the scope of the document.

Book Description
Project Portfolios in Dynamic Environments: Organizing for Uncertainty is a comprehensive report of research that addresses this important, rising issue. Authors Yvan Petit and Brian Hobbs present the results of their investigation in a report that significantly advances the theory and also offers tips for practice. Currently, those applying project portfolio management tend to focus on the selection, prioritization, and strategic alignment of projects. Little attention is afforded the potential disturbances to project portfolios such as new projects, terminated projects, delayed projects, incorrect planning due to high uncertainty, and changes in the external environment. Yet, these factors can have highly disruptive, even show-stopping influence. This research seeks to answer: How is uncertainty affecting project portfolios managed in dynamic environments?

This report indicates that climate change will significantly affect the availability and trade of fish products, especially for those countries most dependent on the sector, and calls for effective adaptation and mitigation actions encompassing food production.

Book Description
Use of and trade in wildlife is a fact of life for human society around the globe. Article IV of the CITES Convention requires that exporting countries restrict trade in Appendix II species to levels that are not detrimental either to species? survival, or to their role within the ecosystems in which they occur (known as the ?non-detriment finding?). Based on two workshops convened by IUCN to develop some pragmatic assistance for Scientific Authorities, this publication presents the background to the development of the non-detriment finding checklist and explains how the checklist itself is designed to work, in the hope that Scientific Authority staff will take and develop the parts of the approach that they find useful.

Book Description
This volume links the abstract theory of demand with its econometric implementation. Exercises lead the reader from elementary utility maximization to the most sophisticated recent techniques, highlighting the main steps in the historical evolution of the subject. The first part presents a brief discussion of duality and flexible forms, and in particular of Deaton and Muellbauer's ``almost ideal demand system''. Part two includes the author's work on true wage indexes, and on intertemporal utility maximization.

Book Description
This extensively revised, restructured, and updated edition continues to present an engaging and comprehensive introduction to the subject, exploring the world’s landforms from a broad systems perspective. It covers the basics of Earth surface forms and processes, while reflecting on the latest developments in the field. Fundamentals of Geomorphology begins with a consideration of the nature of geomorphology, process and form, history, and geomorphic systems, and moves on to discuss: structure: structural landforms associated with plate tectonics and those associated with volcanoes, impact craters, and folds, faults, and joints process and form: landforms resulting from, or influenced by, the exogenic agencies of weathering, running water, flowing ice and meltwater, ground ice and frost, the wind, and the sea; landforms developed on limestone; and landscape evolution, a discussion of ancient landforms, including palaeosurfaces, stagnant landscape features, and evolutionary aspects of landscape change. This third edition has been fully updated to include a clearer initial explanation of the nature of geomorphology, of land surface process and form, and of land-surface change over different timescales. The text has been restructured to incorporate information on geomorphic materials and processes at more suitable points in the book. Finally, historical geomorphology has been integrated throughout the text to reflect the importance of history in all aspects of geomorphology. Fundamentals of Geomorphology provides a stimulating and innovative perspective on the key topics and debates within the field of geomorphology. Written in an accessible and lively manner, it includes guides to further reading, chapter summaries, and an extensive glossary of key terms. The book is also illustrated throughout with over 200 informative diagrams and attractive photographs, all in colour.

Book Description
The Visible and the Invisible contains the unfinished manuscript and working notes of the book Merleau-Ponty was writing when he died. The text is devoted to a critical examination of Kantian, Husserlian, Bergsonian, and Sartrean method, followed by the extraordinary "The Intertwining--The Chiasm," that reveals the central pattern of Merleau-Ponty's own thought. The working notes for the book provide the reader with a truly exciting insight into the mind of the philosopher at work as he refines and develops new pivotal concepts.
