The Polar Regions is a systematic investigation of both the geopolitical commonalties and the differences between the Arctic and the Antarctic. It is the first book to integrate polar studies of this nature with teaching and research on political geography and geopolitics. Based on the premise that geopolitical isolation of the polar regions stands substantially eroded today, the book argues that the contemporary polar scene should be approached and understood in terms of its broader regional as well as global context. It also argues that in the 21st century the two polar regions will be increasingly valued not only for their intrinsic polar merits, but also for their contribution to an understanding of global problems. A critical evaluation of the promise and the performance of the Antarctic Treaty System is provided. The book also examines the ongoing debate about Antarctica, which underlines the need to look beyond the present agreement on the Antarctic and to address the geopolitical implications of it. By presenting studies of both polar regions, this book seeks to test assumptions about the new geopolitics and to evaluate the prospects of it in these regions. The text will be of particular interest to political geographers and specialists in international relations, but will also be an important text for students and researchers in political geography, environmental management and environmental politics.

A long-held belief of political scientists is that moderate voices in the Senate act as power brokers between the ideological poles, yet year after year we see partisan gridlock in Congress. Some even argue that the shrinking number of moderates only increases their political influence. In Life in the Middle, Neilan S. Chaturvedi argues that the belief in the powerful, pivotal moderate neglects their electoral circumstances and overestimates their legislative power. In other words, not all Senators are elected under equal circumstances. Chaturvedi posits that, unlike their ideological counterparts who are elected from states that share an ideological identity, moderates are elected from one of two constituencies: states that have a partisan lean to one party but have enough "swing voters" to vote in a moderate from the opposite party, or states that are nearly evenly divided in terms of partisanship. Using unique interview data with legislative directors, retired United States Senators, and data compiled from the Congressional Record, Chaturvedi shows that, because of their precarious electoral circumstances, moderate senators must avoid active participation on bills and pushing controversial legislation. Lawmaking is much more variable and less moderating than previous theories assumed, as the process relies less on the work of moderates and more on party leaders. The book also demonstrates that mainstream concerns about polarization and its negative effects of increased gridlock and ideological legislation are true.

Food legumes are important constituents of human and animal nutrition, supplying high quality proteins crucial for a balanced diet. These crops also play an important role in low-input agricultural production systems by fixing atmospheric nitrogen. Despite systematic and continuous breeding efforts by legume researchers all over the world, substantial genetic gains have not been achieved. These issues require immediate attention, and overall, a paradigm shift is needed in breeding strategies to strengthen our traditional crop improvement programs. To this end, "Biology and Breeding of Food Legumes" provides extensive information on their history, origin, evolution and botany, as well as breeding objectives and procedures, nutritional improvement, industrial uses, post-harvest technology and recent developments made through biotechnological intervention.
