\"In the fourteenth century the Old World witnessed a series of profound and abrupt changes in the trajectory of long-established historical trends. Transcontinental networks of exchange fractured and an era of economic contraction and demographic decline dawned from which Latin Christendom would not begin to emerge until its voyages of discovery at the end of the fifteenth century. In a major new study of this 'Great Transition,' Bruce Campbell assesses the contributions of commercial recession, war, climate change, and eruption of the Black Death to a far-reaching reversal of fortunes from which no part of Eurasia was spared. The book synthesises a wealth of new historical, palaeo-ecological and biological evidence, including estimates of national income, reconstructions of past climates, and genetic analysis of DNA extracted from the teeth of plague victims, to provide a fresh account of the creation, collapse and realignment of Western Europe's late medieval commercial economy\"-- Provided by publisher.

Forests and woodlands provide an enormous range of goods and services to society, from timber and firewood to medicinal plants, watershed protection, destinations for tourists and sacred sites. Only when these are understood and valued can forests and their resources be properly managed and conserved. This work shows how the complicated network of benefits can be untangled and sets out the different approaches needed to value them. It covers the analysis of plant-based markets, non-market valuation and decision frameworks such as cost-benefit analysis.

We determined the incidence of cryptosporidiosis in children aged <5 years presenting with diarrhoea in an urban and rural hospital-based setting in Malawi. Stools were collected over a 22-month period during both rainy and dry seasons. A range of microscopic methods were used to determine the presence of Cryptosporidium spp. oocysts. Species determination was by polymerase chain reaction–restriction fragment length polymorphism (PCR–RFLP) of oocyst-extracted DNA using 18S rRNA and COWP gene loci. Cryptosporidium spp. oocysts were seen in 5·9% (50/848) of samples, of which 43 amplified by PCR–RFLP indicated the following species: C. hominis, C. parvum, C. hominis/C. parvum, C. meleagridis and C. andersoni. Seven samples could not be amplified by PCR. Wider species diversity was found in the rural setting, and may be a result of increased malnutrition and zoonotic exposure in this area. Improvements in water, sanitation, household hygiene and animal control are required to reduce the incidence of infection in this population.

The purpose of this study was to determine the effect of a 4-week balance training program on specified functional tasks. Thirty-six subjects (age = 22.7 ± 2.10 years; height = 168.30 ± 9.55 cm; weight = 71.15 ± 16.40 kg) were randomly placed into control (C; n = 19) and experimental groups (Tx; n = 17). The Tx group trained using a commercially available balance training device (BOSU). Postural limits (displacement and sway) and functional task (time on ball, shuttle run, and vertical jump) were assessed during a pretest (T1), a posttest (T2), and 2 weeks posttraining (T3). Multivariate repeated measures analysis (a = 0.05) revealed significant differences in time on ball, shuttle run, total sway, and fore/aft displacement after the exercise intervention (T2). T3 assessment revealed that total sway and time on ball remained controlled; however, no other measures were retained. Balance training improved performance of selected sport-related activities and postural control measures, although it is unclear whether the effect of training would transfer to general functional enhancement.

Very little has yet been written about the cultural or economic contributions of woodcarving to people's livelihoods or the consequences of felling hardwood and softwood trees for the international woodcarving trade. Carving Out a Future is the first examination of this trade and its critical links to rural livelihoods, biodiversity, conservation, forestry and the international trade regime. A range of case studies from Australia, Bali, India,Africa and Mexico provides a lens for examining the critical issues relating to the significant impacts of woodcarving on forests, conservation efforts, the need to promote sustainable rural livelihoods and efforts to promote trade so that skilled artisans in developing countries get a fair economic return.

There is an increasing interest in understanding the role forest products and forest resource management in rural livelihoods and poverty reduction strategies. This study investigates the contribution of forest resources to the livelihoods of rural households under a participatory management arrangement in southern Ethiopia. Data were collected through key informant interviews, group discussion, and household surveys from a total of 350 households. Income data were collected in four separate seasons at intervals of three months. The result indicates that forest products are the most important sources of income contributing to 34% and 53% of household per capita income and per capita cash income, respectively. Forest income also helps 20% of the population to remain above the poverty line. Forest income reduces inequality (Gini coefficient) by 15.5%. In general, the result confirms the importance of forest income in poverty alleviation and as safety nets in times of income crisis.

This book, which contains 15 separately authored chapters, discusses both the principles and applications of an integrated approach to natural resource management. Such an approach must embrace the complexity of systems and redirect research towards the greater inclusion of issues such as participatory approaches, multi-scale analysis and an array of tools for system analysis, information management and impact assessment. Case studies, particularly from developing countries in Asia, Africa and Latin America, are included. This book is of interest to a wide range of readers in many disciplines, including forestry, soil and management sciences, agriculture, and development studies.

This book discusses both the principles and applications of an integrated approach to natural resources management. It deals directly with the wider integration of natural resources, including the complexity of systems and redirecting research towards including participatory approaches, multi-scale analysis and an array of tools for system analysis, information management and impact asessment.This book has been developed from papers first presented at a workshop in Penang, Malaysia in 2000. Each paper has been peer-reviewed, revised and updated up to the end of 2002. Case studies from around the world, particularly Asia, Africa and Latin America, are presented by international experts.

More than half a century after the advent of the nuclear age, is the world approaching a tipping point that will unleash an epidemic of nuclear proliferation? Today many of the building blocks of a nuclear arsenal-scientific and engineering expertise, precision machine tools, software, design information-are more readily available than ever before. The nuclear pretensions of so-called rogue states and terrorist organizations are much discussed. But how firm is the resolve of those countries that historically have chosen to forswear nuclear weapons? A combination of changes in the international environment could set off a domino effect, with countries scrambling to develop nuclear weapons so as not to be left behind-or to develop nuclear \"hedge\" capacities that would allow them to build nuclear arsenals relatively quickly, if necessary. The Nuclear Tipping Point examines the factors, both domestic and transnational, that shape nuclear policy. The authors, distinguished scholars and foreign policy practitioners with extensive government experience, develop a framework for understanding why certain countries may originally have decided to renounce nuclear weapons-and pinpoint some more recent country-specific factors that could give them cause to reconsider. Case studies of eight long-term stalwarts of the nonproliferation regime-Egypt, Germany, Japan, Saudi Arabia, South Korea, Syria, Turkey, and Taiwan-flesh out this framework and show how even these countries might be pushed over the edge of a nuclear tipping point. The authors offer prescriptions that would both prevent such countries from reconsidering their nuclear option and avert proliferation by others. The stakes are enormous and success is far from assured. To keep the tipping point beyond reach, the authors argue, the international community will have to act with unity, imagination, and strength, and Washington's leadership will be essential.
