This book is an introduction to a basic property of life, one mostly unknown to science and the public until the latter half of the last century: Humans, plants, and animals have within their bodies a kind of clock that synchronizes much of what they do throughout their lives to the time ofday and the seasons, and in the case of the sea-dwelling organisms, the tides. This timepiece performs its service autonomously - it rules silently within us without us giving a thought to it.Three chapters are devoted to the human clock: its disruptive action in transmeridional travel and shift work, its oversight in most every aspect of our physiology, and how doctors being aware of its action can save lives. Other major subjects describe the role in piloting birds in homing andmigration, guiding the seasonal reproduction of plants and animals, and its influence on shore dwellers. The book closes with a description of the clockworks' escapement.

Consolidation in the private health insurance (PHI) industry may be resulting in less competitive markets and contributing to rising health insurance rates paid by consumers and employers. However, measuring the extent of changes in market competition over time or the effects of changes is challenging. Researchers have used the data available to study competition in PHI markets, typically using one of two measures of competition: HMO market concentration; or the number of HMOs in a market. This report summarizes the findings of peer-reviewed research on concentration in PHI markets and the relationship between the level of competition and other variables, such as premium prices and provider reimbursement rates.

Part I covers modern advances in the determination ofglycoprotein structure and in the biosynthesis of mammalian,bacterial, yeast, plant and insect glycoproteins. There are alsotwo chapters on functional aspects (glycoprotein hormones andcollagens).The content of the volume is very comprehensive in that, mostcontributors have focussed on discussing, in depth, the wealthof most recent advances in their field, and referring to previousreviews of older work for background information. This method caneffectively produce a very wide subject coverage in a smallernumber of chapters/volumes.The volume is an importantinformation source for all glycobiologist researchers (seniorinvestigators, post-doctoral fellows and graduate students), andas a good, comprehensive, reference text for scientists working inthe life sciences.
