The brain is the most complex organ in our body. Indeed, it is perhaps the most complex structure we have ever encountered in nature. Both structurally and functionally, there are many peculiarities that differentiate the brain from all other organs. The brain is our connection to the world around us and by governing nervous system and higher function, any disturbance induces severe neurological and psychiatric disorders that can have a devastating effect on quality of life. Our understanding of the physiology and biochemistry of the brain has improved dramatically in the last two decades. In particular, the critical role of cations, including magnesium, has become evident, even if incompletely understood at a mechanistic level. The exact role and regulation of magnesium, in particular, remains elusive, largely because intracellular levels are so difficult to routinely quantify. Nonetheless, the importance of magnesium to normal central nervous system activity is self-evident given the complicated homeostatic mechanisms that maintain the concentration of this cation within strict limits essential for normal physiology and metabolism. There is also considerable accumulating evidence to suggest alterations to some brain functions in both normal and pathological conditions may be linked to alterations in local magnesium concentration. This book, containing chapters written by some of the foremost experts in the field of magnesium research, brings together the latest in experimental and clinical magnesium research as it relates to the central nervous system. It offers a complete and updated view of magnesiums involvement in central nervous system function and in so doing, brings together two main pillars of contemporary neuroscience research, namely providing an explanation for the molecular mechanisms involved in brain function, and emphasizing the connections between the molecular changes and behavior. It is the untiring efforts of those magnesium researchers who have dedicated their lives to unraveling the mysteries of magnesiums role in biological systems that has inspired the collation of this volume of work.

Obesity is a national epidemic in the United States. It is estimated that by 2018 the cost of treating weight-related illnesses will double to almost $350 billion a year, while a 2010 report by the US Surgeon General estimates that two-thirds of American adults and almost one in three children are now overweight or obese. This volume originated in a special 2009 symposium funded in part by a grant from the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) and sponsorship from Mars WalthamA on how human-animal interaction may help fight obesity across the lifespan. The authors present scientific evidence about the benefits of dog walking for improving human and animal health, and case studies of programs that are using this powerful expression of the human-animal bond to combat obesity. The volume is especially valuable as a sourcebook of evidence-based studies for public health professionals treating overweight humans and veterinarians treating obese dogs.

This valuable reference delineates the ground water quality concerns associated with the planning and usage of septic tank systems. Septic tank systems represent a significant source of ground water pollution in the United States. Since many existing systems are exceeding their design life by several-fold, the usage of synthetic organic chemicals in the household and for system cleaning is increasing, and larger-scale systems are being designed and used.

The new edition of this annual publication (previously published solely by IFOAM and FiBL) documents recent developments in global organic agriculture. It includes contributions from representatives of the organic sector from throughout the world and provides comprehensive organic farming statistics that cover surface area under organic management, numbers of farms and specific information about commodities and land use in organic systems. The book also contains information on the global market of the burgeoning organic sector, the latest developments in organic certification, standards and regulations, and insights into current status and emerging trends for organic agriculture by continent from the worlds foremost experts. For this edition, all statistical data and regional review chapters have been thoroughly updated. Completely new chapters on organic agriculture in the Pacific, on the International Task Force on Harmonization and Equivalence in Organic Agriculture and on organic aquaculture have been added. Published with IFOAM and FiBL

This volume presents for the first time a collection of historically important papers written on the concept of rationality in the social sciences. In 1939-40, the famed Austrian economist Joseph A. Schumpeter and the famous sociologist Talcott Parsons convened a faculty seminar at Harvard University on the topic of rationality. The first part includes their essays as well as papers by the Austrian phenomenologist Alfred Schütz, the sociologist Wilbert Moore, and the economist Rainer Schickele. Several younger economists and sociologists with bright futures also participated, including Alex Gerschenkron, John Dunlop, Paul M. Sweezy, and Wassily W. Leontief, who was later awarded the Nobel Prize for developing input-output analysis. The second part presents essays and commentaries written by today’s internationally noted social scientists and addressing the topic of rationality in social action from a broad range of perspectives. The book’s third and final part shares the recently discovered correspondence between the seminar principals regarding the original but failed plan to publish its proceedings. It also includes letters, not previously published, between Richard Grathoff, Walter M. Sprondel and Talcott Parsons on the rationality seminar and the exchanges between Parsons and Schütz.

The material in Values of American Society remains the principal resource for understanding Parsons' conception of value systems. His treatment of value systems has been much debated, although poorly understood, in considerable part because Parsons never published his full conception, developed only in these manuscripts. They continue to hold interest for social scientists, both for their carefully developed analytical scheme and for the resulting discussion of American culture and society.
