Book Description
This book represents the first multidisciplinary scientific work on a deep volcanic maar lake in comparison with other similar temperate lakes. The syntheses of the main characteristics of Lake Pavin are, for the first time, set in a firmer footing comparative approach, encompassing regional, national, European and international aquatic science contexts. It is a unique lake because of its permanently anoxic monimolimnion, and furthermore, because of its small surface area, its substantially low human influence, and by the fact that it does not have a river inflow. The book reflects the scientific research done on the general limnology, history, origin, volcanology and geological environment as well as on the geochemistry and biogeochemical cycles. Other chapters focus on the biology and microbial ecology whereas the sedimentology and paleolimnology are also given attention. This volume will be of special interest to researchers and advanced students, primarily in the fields of limnology, biogeochemistry, and aquatic ecology.
Heritage Sites of Astronomy and Archaeoastronomy in the Context of the UNESCO World Heritage Convention
Author: Clive L. N. RugglesPublisher:
ISBN: 9780954086770
Category : Archaeoastronomy
Languages : en
Pages : 304
Book Description
This joint venture between ICOMOS, the advisory body to UNESCO on cultural sites, and the International Astronomical Union is the second volume in an ongoing exploration of themes and issues relating to astronomical heritage in particular and to science and technology heritage in general. It examines a number of key questions relating to astronomical heritage sites and their potential recognition as World Heritage, attempting to identify what might constitute "outstanding universal value" in relation to astronomy. "Heritage Sites of Astronomy and Archaeoastronomy--Volume 2" represents the culmination of several years' work to address some of the most challenging issues raised in the first ICOMOS-IAU Thematic Study, published in 2010. These include the recognition and preservation of the value of dark skies at both cultural and natural sites and landscapes; balancing archaeoastronomical considerations in the context of broader archaeological and cultural values; the potential for serial nominations; and management issues such as preserving the integrity of astronomical sightlines through the landscape.Its case studies are developed in greater depth than those in volume 1, and generally structured as segments of draft nomination dossiers. They include seven-stone antas (prehistoric dolmens) in Portugal and Spain, the thirteen towers of Chankillo in Peru, the astronomical timing of irrigation in Oman, Pic du Midi de Bigorre Observatory in France, Baikonur Cosmodrome in Kazakhstan, and Aoraki-Mackenzie International Dark Sky Reserve in New Zealand. A case study on Stonehenge, already a World Heritage Site, focuses on preserving the integrity of the solstitial sightlines.As for the first ICOMOS-IAU Thematic Study, a international team of authors including historians, astronomers and heritage professionals is led by Professor Clive Ruggles for the IAU and Professor Michel Cotte for ICOMOS.
Getting MAD: Nuclear Mutual Assured Destruction, Its Origins and Practice

Pages : 369
Book Description
Nearly 40 years after the concept of finite deterrence was popularized by the Johnson administration, nuclear Mutual Assured Destruction (MAD) thinking appears to be in decline. The United States has rejected the notion that threatening population centers with nuclear attacks is a legitimate way to assure deterrence. Most recently, it withdrew from the Anti-Ballistic Missile Treaty, an agreement based on MAD. American opposition to MAD also is reflected in the Bush administration's desire to develop smaller, more accurate nuclear weapons that would reduce the number of innocent civilians killed in a nuclear strike. Still, MAD is influential in a number of ways. First, other countries, like China, have not abandoned the idea that holding their adversaries' cities at risk is necessary to assure their own strategic security. Nor have U.S. and allied security officials and experts fully abandoned the idea. At a minimum, acquiring nuclear weapons is still viewed as being sensible to face off a hostile neighbor that might strike one's own cities. Thus, our diplomats have been warning China that Japan would be under tremendous pressure to go nuclear if North Korea persisted in acquiring a few crude weapons of its own. Similarly, Israeli officials have long argued, without criticism, that they would not be second in acquiring nuclear weapons in the Middle East. Indeed, given that Israelis surrounded by enemies that would not hesitate to destroy its population if they could, Washington finds Israel's retention of a significant nuclear capability totally "understandable."

PROMOTION DE LA SANTE ET AUTONOMISATION DANS LE CONTEXTE AFRICAIN

Book Description
Le terme promotion de la santé en Afrique, près de 30 ans après l'adoption de la Charte d'Ottawa, continue d'avoir des connotations complètement hors du sens que lui confère cette charte. Cela n'est pas étonnant quand on sait que la notion de santé dans ce contexte africain équivaut à la lutte contre la maladie à travers les soins de santé dispensés par des professionnels de la santé dans des formations sanitaires et les hôpitaux. L'évolution que connait le continent depuis quelques décennies est de donner un peu plus de place à la communauté à travers les relais communautaires dans une participation communautaire vidée de son contenu, car le pouvoir n'est jamais passé entre les mains des communautés.C'est au vu de tout ceci que le présent ouvrage à sa raison d'être pour expliquer les fondements de l'autonomisation communautaire et de la promotion de la santé avec leur importance pour la région africaine en proie aux mauvais indicateurs de santé comparativement aux autres régions du monde.
Water & Heritage
Author: Willem WillemsPublisher:
ISBN: 9789088903861
Category : Business & Economics
Languages : en
Pages : 434
Book Description
Water is vital for life, and its availability has been a concern for mankind throughout the ages. Its presence has always been ascertained in a variety of ways and the development of human society everywhere is connected with various forms of water management. Man also needed to manage water to find protection from its dangers and the need for that is increasing. In the coming decades, the impact of climate change is expected to intensify floods and droughts, affect groundwater resources, raise sea levels, increase pollution and enhance the frequency and magnitude of disasters. Societies around the world are challenged to adapt to these threats to ensure water security, economic prosperity and environmental and cultural sustainability. This book deals with the heritage of water management and the use that was made of water, as well as the impact of water management on heritage. An example of the former may be an ancient irrigation system in the Filipines or in the Middle East that still functions today, while the latter may reflect the importance of maintaining groundwater levels for the preservation of organic remains on archaeological sites or of wooden piles underneath standing buildings. In either case the papers in this book reflect the dynamic nature of water, and hence the equally dynamic relation between water management and heritage. This publication follows up on a Heritage and Water conference in Amsterdam, the first of its kind. Its main purpose is to credibly present the importance and value of heritage and historical experience for water and sustainable development, and vice versa, present the importance of water management for the protection of heritage. It presents evolving insights and concepts about Water and about Heritage from a variety of disciplines, policy and public perspectives illustrated with cases studies and aims to connect decision makers with experts such as engineers, archaeologists, historians, geographers, ecologist and landscape architects
Making Aid Work
Author: Abhijit Vinayak BanerjeePublisher: MIT Press
ISBN: 0262260395
Category : Business & Economics
Languages : en
Pages : 68
Book Description
An encouraging account of the potential of foreign aid to reduce poverty and a challenge to all aid organizations to think harder about how they spend their money. With more than a billion people now living on less than a dollar a day, and with eight million dying each year because they are simply too poor to live, most would agree that the problem of global poverty is our greatest moral challenge. The large and pressing practical question is how best to address that challenge. Although millions of dollars flow to poor countries, the results are often disappointing. In Making Aid Work, Abhijit Banerjee—an "aid optimist"—argues that aid has much to contribute, but the lack of analysis about which programs really work causes considerable waste and inefficiency, which in turn fuels unwarranted pessimism about the role of aid in fostering economic development. Banerjee challenges aid donors to do better. Building on the model used to evaluate new drugs before they come on the market, he argues that donors should assess programs with field experiments using randomized trials. In fact, he writes, given the number of such experiments already undertaken, current levels of development assistance could focus entirely on programs with proven records of success in experimental conditions. Responding to his challenge, leaders in the field—including Nicholas Stern, Raymond Offenheiser, Alice Amsden, Ruth Levine, Angus Deaton, and others—question whether randomized trials are the most appropriate way to evaluate success for all programs. They raise broader questions as well, about the importance of aid for economic development and about the kinds of interventions (micro or macro, political or economic) that will lead to real improvements in the lives of poor people around the world. With one in every six people now living in extreme poverty, getting it right is crucial.
