The Poetry of the Old Northern Tongue from the Earliest Times to the Thirteenth Century

Corpus Poeticum Boreale

Douglas H. Powell

After the age of 40, we may notice occasional lapses--a forgotten phone number, a friend's name, or a word that was right on the tip of our tongue. By 60, we may find ourselves wondering who called this morning, why we came into the kitchen, where we parked the car. In an aging nation, where one citizen in seven will be 65 when the next century arrives, these little difficulties raise a larger question: What precisely happens to our thinking as we grow older? What is normal, what is not, and how are we to know the signs? Douglas Powell offers a comprehensive account of cognitive aging, of how our mental functions change as we mature. Defining patterns of normal decline, as well as severe forms of cognitive impairment, this book will help us understand and address the needs of an aging population. Powell integrates the latest literature on aging with the findings of his recent study of 1,000 physicians and 600 other subjects ranging in age from 25 to 92. His work reveals patterns of cognitive aging throughout the life cycle, particularly the way in which variability among individuals outpaces the decline of overall ability. Tackling an issue of growing interest in the field of gerontology, he notes the effect of certain factors such as gender, diet, health, and physical and mental exercise on changes in cognitive functioning over time. Along with the criteria for mild cognitive impairment and normal cognitive aging, this book addresses the question of optimal cognitive aging, identifying its characteristics and searching out their implications for the maintenance of intellectual abilities in the post-retirement years.

Profiles in Cognitive Aging

This book is about the peaceful resolution (PR) of territorial and maritime disputes and states' strategic behavior vis-à-vis methods of peaceful resolution: bilateral negotiations, good offices, inquiry, conciliation, mediation, arbitration, and adjudication. The authors argue that the high stakes associated with settlement of territorial and maritime disputes, the diversity of PR methods employed, and unpredictability of outcomes push states to strategize. Strategic considerations undergird states' choice of the particular PR methods, and states' behavior during the resolution once a particular method such as adjudication or negotiations, has been initiated. Uncertainty about the outcome drives states to pursue "strategic selection." The process of strategic selection occurs at two interrelated stages: the initial pursuit of a particular method and venue--choice-of-venue strategic selection, and decision-making once a PR method/venue has been identified--within-venue strategic selection. The driving force behind strategizing in these two settlement stages is the hope of reducing uncertainty and of increasing the chances of winning. Importantly, as the disputants progress through the settlement process, states reconsider and refine these strategies. For each stage of strategic selection, Powell and Wiegand identify several mechanisms that influence states' strategies, including past experiences with PR methods (winning/losing), the relationship between domestic law and international law, framing legal claims, and shaping the resolution procedures. This book embraces a multi-method approach and combines statistical analyses and in-depth qualitative interviews with states' legal counsel, judges, arbitrators, government officials, and other experts from multiple countries. The book also highlights numerous real-world instances of territorial and maritime disputes including the Philippines v. China arbitration case in the South China dispute.
