In pioneering work in the 1950s, S. Karlin and J. McGregor showed that probabilistic aspects of certain Markov processes can be studied by analyzing orthogonal eigenfunctions of associated operators. In the decades since, many authors have extended and deepened this surprising connection between orthogonal polynomials and stochastic processes. This book gives a comprehensive analysis of the spectral representation of the most important one-dimensional Markov processes, namely discrete-time birth-death chains, birth-death processes and diffusion processes. It brings together the main results from the extensive literature on the topic with detailed examples and applications. Also featuring an introduction to the basic theory of orthogonal polynomials and a selection of exercises at the end of each chapter, it is suitable for graduate students with a solid background in stochastic processes as well as researchers in orthogonal polynomials and special functions who want to learn about applications of their work to probability.

Agricultural production is highly sensitive to weather and climate-related disasters such as drought, storm and flood. While it is not possible to prevent the occurrence of natural disasters, the resultant disastrous effects can be reduced mitigated through proper planning and effective preparation. This book, based on a gathering of experts in Beijing, discusses ways to reduce the vulnerability of agriculture to disaster and extreme events, both by accurate and timely warning, and by impact-reducing countermeasures.

Although all living beings modify their environment, human beings have acquired the ability to do so on a superlative space-time scale. As a result of industrialization and the use of new technologies, the anthropogenic impact has been increasing in the last centuries, causing reductions in the sizes or the extinction of numerous wild populations. In this sense, from the field of conservation genetics, various efforts have been made in recent decades to provide new knowledge that contributes to the conservation of populations, species, and habitats. In this book, we summarize the concrete contributions of researchers to the conservation of the Neotropical mammals using Molecular Ecology techniques. The book is divided into three major sections. The first section provides an up-to-date review of the conservation status of Neotropical mammals, the applications of the molecular markers in its conservation, and the use of non-invasive and forensic genetic techniques. The second and third sections present, respectively, a series of case studies in various species or taxonomic groups of Neotropical mammals.

In order to feed the world, global agriculture will have to double food production by 2050. As a result, the use of soils with fertilizers and pesticides in agronomic ecosystems will increase, taking into account the sustainability of these systems and also the provision of food security. Thus, soil ecosystems, their health, and their quality are directly involved in sustainable agronomical practices, and it is important to recognize the important role of soil microbial communities such as mycorrhizal fungi, their biodiversity, interactions, and functioning. Soil ecosystems are under the threat of biodiversity loss due to an increase of cultivated areas and agronomic exploitation intensity. Also, changes in land use alter the structure and function of ecosystems where biodiversity is vital in the ecosystem. Soils are a major aid in food production in all terrestrial ecosystems; however, this means they are also involved in gas emission and global warming. Thus, in agronomic ecosystems, several mitigation practices have been proposed to promote the increase of carbon soil stock, and the reduction of warming gas emission from soils. In South America, most of the rural population depends economically on agriculture and usually works in family units. New, organic, safe, and sustainable agro-forestry practices must be applied to support local communities and countries to achieve hunger eradication, rural poverty reduction, and sustainable development. This book compiles new information for mycorrhizal occurrence in natural and anthropic environments in South America. It includes new reports of mycorrhizal fungi diversity along different mycorrhizal types and their effect on plant communities, plant invasions, the use of mycorrhizal fungi for ecological and sustainable studies, management programs of natural and agroecosystems, and forestry and food-secure production. This book fills the gaps in biodiversity knowledge, management and safe food production of mycorrhizas. It should be a valuable help to researchers, professors and students, to aid in use of mycorrhizal fungi while also focusing on their biodiversity, sustainable safe food production, and conservation perspectives.

'Public-Private Partnerships for Urban Water Utilities: A Review of Experiences in Developing Countries' analyzes the market growth of Public-Private Partnerships (PPPs) in the developing world since 1990, and the performance of more than 65 large water PPP projects representing more than 100 million people for access, service quality, operational efficiency, and tariff levels. Although a relatively small portion of the water utilities in the developing world are operated under PPPs (about 7 percent in 2007), the urban population served by private water operators has grown every year since 1990. Despite many difficulties encountered by PPP projects and a few contract terminations, a large majority of contracts awarded since 1990 are still in place. The track record for improving service and efficiency reaffirms the value of PPPs to help turn around poorly performing water utilities, even though the level of private financing did not match initial expectations. Over time, a more realistic market has developed, the number of private investors from developing countries has grown, and contract designs have become more pragmatic concerning risk allocations between partners. The water sector has many features that set it apart from other infrastructure sectors. This book suggests the need for careful consideration of those specificities to successfully involve private operators. Although concessions with private financing have worked in a few places, contractual arrangements that combine private operation with public financing appear to be the most sustainable option in many countries. Policy makers, stakeholders, and donors need to remain heavily engaged in the water sector, especially in the poorest countries and during a global financial crisis. This book contributes to a better understanding of the various options to tackle the many challenges of providing water and sanitation services to urban populations in the developing world.

What are European archaeologists doing abroad? What have they been doing there for the past three to four centuries? Are they doing things differently nowadays? To address these questions, this book explores the scope, impact and ethics of European archaeological policies and practices in the Mediterranean area, the Near East, sub-Saharan Africa, Asia and Latin America. Acknowledging that international and transcultural projects have a range of different stakeholders, the first part of this book aims to identify some of the values and motivations behind different European archaeologies abroad. This is done by providing thorough historical overviews on a range of European countries, including France, Spain, Germany, Belgium, the Netherlands and Poland. But how are these values translated, through socio-political, theoretical and administrative frameworks, unto local circumstances in host countries? And how are these archaeological activities received locally? The second part of this book attempts to answer these questions through a range of historical and contemporary case studies, in Africa, in Asia, in South America, in the Near East and in Europe. The third part of the book offers several critical reflections on European values, motivations and collaboration projects, as perceived by archaeological heritage professionals based in, and/or working in Senegal, Sudan, Somaliland, Colombia, and the Near East. This collection of historical overviews, contemporary case studies and critical reflections focuses on the challenging relationships between archaeological practices and policies, including the requirements and wishes of archaeologists, of local communities and of other stakeholders in Europe and in the host countries. In addition to researchers and students, this book should be of interest to practicing archaeologists, heritage professionals and policy makers the world over, as they seek to reach better informed decisions regarding archaeological projects and international collaboration. This publication was produced in the framework of the ACE project – “Archaeology in Contemporary Europe. Professional Practices and Public Outreach”, with the support of the Culture 2007-2013 programme of the European Commission.
