This collection of original papers presents current research on linguistic aspects of the Spanish used in the United States. The authors examine such topics as language maintenance and language shift, language choice, the bilingual's discourse patterns, varieties of Spanish used in the United States, and oral proficiency testing of bilingual speakers. In view of the fact that Hispanics constitute the largest linguistic minority in the United States, the pioneering work in the area of sociolinguistic issues in the U.S. Spanish presented here is of great importance.

The global energy scene is in a state of flux. Large-scale shifts include: the rapid deployment and steep declines in the costs of major renewable energy technologies; the growing importance of electricity in energy use across the globe; profound changes in China's economy and energy policy, moving consumption away from coal; and the continued surge in shale gas and tight oil production in the United States. These changes provide the backdrop for the World Energy Outlook-2017, which includes a full update of energy demand and supply projections to 2040 based on different scenarios. The projections are accompanied by detailed analyses of their impact on energy industries and investment, as well as implications for energy security and the environment. The report this year includes a focus on China, which examines how China's choices could reshape the global outlook for all fuels and technologies. A second focus, on natural gas, explores how the rise of shale gas and LNG are changing the global gas market as well as the opportunities and risks for gas in the transition to a cleaner energy system. Finally, the WEO-2017 introduces a major new scenario - the Sustainable Development Scenario - that outlines an integrated approach to achieving internationally agreed objectives on climate change, air quality and universal access to modern energy.

In light of the rapid fluctuations in oil prices and subsequent impact on the stability and economic perspectives of energy producing and energy importing states in the Western Hemisphere, this book stresses the urgency to integrate sustainability at the very core of national energy security strategies. From Canada to Argentina, this edited volume analyzes a series of case studies and diverging paradigms across the continent. It underlines how the relatively recent exploitation of unconventional energy sources in North America and the resulting impact on prices impact the geopolitical concerns of traditional producers. It also explains how much energy strategies are central to the development of national economies and the stability of their society. Highlighting the shortcomings in several countries even at a time of high prices, the volume makes the case for an inclusive and holistic approach to energy security that would integrate environmental concerns at its very core. This edited volume also explains how this new energy independence of the western Hemisphere affects its foreign policy with the main international actors in the field of energy whether traditional producers or consumers. Finally, it provides key insights on successful strategy towards the development of alternative sources of energy.
