Life Out of Balance

Homeostasis and Adaptation in a Darwinian World

By: Joel B. Hagen

Traces historical developments in scientific conceptions of physiology, ecology, behavior, and evolutionary biology during the mid-twentieth century Life Out of Balance focuses on a period in history when new ideas of self-regulation, adaptation, and fitness became central to a variety of biological disciplines. During the decades surrounding World War II, these ideas developed in several quite different contexts and led to greater debates about the merits of such models as applied to larger systems, including society at large. Particularly in its later cybernetic form, homeostasis seemed to provide new ways of discussing balance and regulation that avoided discredited approaches of earlier champions of vitalism and mechanism. It provided a common perspective and terminology for discussing self-regulating “systems,” whether biological, mechanical, or social. Although enormously fruitful and influential, homeostatic perspectives also generated numerous controversies when critics questioned the degree to which biological systems are characterized by balance and self-regulation. Resolving these controversies continues to be a challenge in modern biology. If natural selection constitutes the first law of biology, scientists who champion homeostasis as a theoretical model claim that it is a second law, equally important and closely related to the first. Such claims notwithstanding, homeostasis has generated a series of controversies since it was formalized by Walter Cannon in the late 1920s. Critics contended that Cannon took a too-optimistic view of life, not only ignoring pathological deviations from normality but also failing to adequately explain the ability of living things to respond adaptively to environmental challenges. Underlying these controversies was the unresolved problem of integrating physiology and other areas of functional biology with the emerging evolutionary synthesis of Mendelian genetics and Darwinian natural selection. The physiological idea of homeostasis as the adaptive “fit” between the organism and its environment and the Darwinian idea of adaptation and fitness in terms of reproductive success might seem to be complementary in an unproblematic way, but historically they have had an uneasy relationship.

An Entangled Bank

The Origins of Ecosystem Ecology

By: Joel Bartholemew Hagen

This book was a revelation. I was simply enthralled by Joel Hagen's brilliance in reviewing the emergence of the discipline of ecosystem ecology (the study of biotic-abiotic interaction and nutrient flows in ecological systems). He does a magnificent job of introducing the personalities that midwived the new science. He explains their intellectual struggles, philosophical cross-currents, and different academic milieux. He also expertly illuminates sociopolitical context. Through his in-depth research he is able to dispel some misconceptions and truismsm, arriving at the heart of what made each scientist tick. Even when exploring some of the arcane figures and dead-end developments, he is so compelling that they become integral to the story, not sidetracks. His breadth of knowledge, his discerning inclusiveness, his clarity of thought, all make _An Entangled Bank_ a stimulating read. Very often in science courses we are presented only with the canonical "state of the science," having to swallow its agglomerated whole free of context. Hagen reveals the wisdom of understanding intellectual foundations. Through study of the origins and development of a science, we may better grasp the received tenets of current scientific understanding. As a young science, ecosystem ecology has a historical context that is relatively accessible to us, if less romantic than a tale of the origins of astronomy might be. A peek into the labs and offices of botanists, limnologists, and biogeochemists might not seem like the acme of excitement. Hagen inspires us with his insights. He makes his subject meaningful to us. Though it is not pleasure reading by any stretch, its clear-sighted intellectual vigor makes _An Entangled Bank_ pure enjoyment.

Hemostasis and Thrombosis

Basic Principles and Clinical Practice

By: Victor J. Marder,William C. Aird,Joel S. Bennett,Sam Schulman,Gilbert C. White, II

Since publication of the First Edition in 1982, Hemostasis and Thrombosis has established itself as the pre-eminent book in the field of coagulation disorders. No other book is as inclusive in scope, with coverage of the field from the standpoint of both basic scientists and clinicians. This comprehensive resource details the essentials of bleeding and thrombotic disorders and the management of patients with these and related problems, and delivers the most up-to-date information on normal biochemistry and function of platelets or endothelial cells, as well as in-depth discussions of the pharmacology of anticoagulant, fibrinolytic, and hemostatic drugs. NEW to the Sixth Edition... • A new team of editors, each a leader in his field, assures you of fresh, authoritative perspectives. • Full color throughout • A companion website that offers full text online and an image bank. • A new introductory section of chapters on basic sciences as related to the field • Entirely new section on Hemostatic and Thrombotic Disorders Associated with Systemic Conditions includes material on pediatric patients, women's health issues, cancer, sickle cell disease, and other groups. • Overview chapters preceding each section address broad topics of general importance. This is the tablet version which does not include access to the supplemental content mentioned in the text.
