This volume focuses on the decision-making potential provided by second language performance assessments. The authors first situate performance assessment within a broader discussion of alternatives in language assessment and in educational assessment in general. They then discuss issues in performance assessment design, implementation, reliability, and validity. Finally, they present a prototype framework for second language performance assessment based on the integration of theoretical underpinnings and research findings from the task-based language teaching literature, the language testing literature, and the educational measurement literature. The authors outline test and item specifications, and they present numerous examples of prototypical language tasks. They also propose a research agenda focusing on the operationalization of second language performance assessments.

"America's Children and the Environment (ACE)" is EPA's report presenting data on children's environmental health. ACE brings together information from a variety of sources to provide national indicators in the following areas: Environments and Contaminants, Biomonitoring, and Health. Environments and Contaminants indicators describe conditions in the environment, such as levels of air pollution. Biomonitoring indicators include contaminants measured in the bodies of children and women of child-bearing age, such as children's blood lead levels. Health indicators report the rates at which selected health outcomes occur among U.S. children, such as the annual percentage of children who currently have asthma. Accompanying each indicator is text discussing the relevance of the issue to children's environmental health and describing the data used in preparing the indicator. Wherever possible, the indicators are based on data sources that are updated in a consistent manner, so that indicator values may be compared over time.

Cities across the globe are looking to develop affordable, environmentally friendly, and socially responsible transportation solutions that can meet the accessibility needs of expanding metropolitan populations and support future economic and urban development. When appropriately planned and properly implemented as part of a larger public transportation network, urban rail systems can provide rapid mobility and vital access to city centers from surrounding districts. High-performing urban rail services, when carefully approached as development projects, can help enhance quality of life by giving citizens access to employment opportunities, essential services, urban amenities, and neighboring communities. The purpose of this Handbook is to synthesize and disseminate knowledge to inform the planning, implementation, and operations of urban rail projects with a view towards: -- Emphasizing the need for early studies and project planning; -- Making projects more sustainable (economically, socially, and environmentally); -- Improving socioeconomic returns and access to opportunities for users; -- Maximizing the value of private participation, where appropriate; and -- Building capacity within project implementing and managing institutions This Handbook provides experiential advice to tackle the technical, institutional, and financial challenges faced by decision makers considering urban rail projects. It brings together the expertise of World Bank staff and the input of numerous specialists to synthesize international 'good practices' and recommendations that are independent of commercial, financial political, or other interests. The material presented is intended as an honest-broker guide to maximize the impact and manage the challenges of urban rail systems in cities in both developed and developing countries. Rather than identify a single approach, this Handbook acknowledges the complexities and context necessary when approaching an urban rail development by helping to prepare decision makers to ask the right questions, consider the key issues, perform the necessary studies, apply adequate tools, and learn from international good practice all at the right time in the project development process.

This book will enable readers to understand the principles underpinning the management of pain which a particular emphasis upon the care of the older adult. The chapters will explore concepts that are recognised to be involved in the pain experience but each author will then add their own unique perspective by applying the principles to their specialist area of practice and the care of the older adult. It is structured to include the aims and outcomes of the chapter at the beginning so that readers can track their progress, and provides chapter outlines and further reading suggestions foir this unique topic area.

The U.S. sheep industry is complex, multifaceted, and rooted in history and tradition. The dominant feature of sheep production in the United States, and, thus, the focus of much producer and policy concern, has been the steady decline in sheep and lamb inventories since the mid-1940s. Although often described as "an industry in decline," this report concludes that a better description of the current U.S. sheep industry is "an industry in transition."

The fields covered by the hydrogen energy topic have grown rapidly, and now it has become clearly multidisciplinary. In addition to production, hydrogen purification and especially storage are key challenges that could limit the use of hydrogen fuel. In this book, the purification of hydrogen with membrane technology and its storage in "solid" form using new hydrides and carbon materials are addressed. Other novelties of this volume include the power conditioning of water electrolyzers, the integration in the electric grid of renewable hydrogen systems and the future role of microreactors and micro-process engineering in hydrogen technology as well as the potential of computational fluid dynamics to hydrogen equipment design and the assessment of safety issues. Finally, and being aware that transportation will likely constitute the first commercial application of hydrogen fuel, two chapters are devoted to the recent advances in hydrogen fuel cells and hydrogen-fueled internal combustion engines for transport vehicles. - Hydrogen from water and biomass considered - Holistic approach to the topic of renewable hydrogen production - Power conditioning of water electrolyzers and integration of renewable hydrogen energy systems considered - Subjects not included in previous books on hydrogen energy - Micro process technology considered - Subject not included in previous books on hydrogen energy - Applications of CFD considered - Subject not included in previous books on hydrogen energy - Fundamental aspects will not be discussed in detail consciously as they are suitably addressed in previous books - Emphasis on technological advancements - Chapters written by recognized experts - Up-to date approach to the subjects and relevant bibliographic references
