Food Webs and Niche Space
What is the minimum dimension of a niche space necessary to represent the overlaps among observed niches? This book presents a new technique for obtaining a partial answer to this elementary question about niche space. The author bases his technique on a relation between the combinatorial structure of food webs and the mathematical theory of interval graphs. Professor Cohen collects more than thirty food webs from the ecological literature and analyzes their statistical and combinatorial properties in detail. As a result, he is able to generalize: within habitats of a certain limited physical and temporal heterogeneity, the overlaps among niches, along their trophic (feeding) dimensions, can...

Examines the structures of the economy and political system of the United States and recommends methods for reforming the American government.
The Cutting Edge
The quest for new challenges and understanding was relentless. In a fascinating section of the book Joel-Cohen describes at first hand his experience of working at Dr Albert Schweitzer's hospital in Lambarene, a vivid contrast to the prosperous private practice and flourishing academic career enjoyed by him at the time. Later, when it seemed that he had achieved all he had set out to do, the author accepted the challenge of uprooting himself from the country where he was born, in order to go to Israel and build up from scratch the obstetric and gynaecology department of the Beilinson Hospital.
Computer Algebra and Symbolic Computation
This book provides a systematic approach for the algorithmic formulation and implementation of mathematical operations in computer algebra programming languages. The viewpoint is that mathematical expressions, represented by expression trees, are the data objects of computer algebra programs, and by using a few primitive operations that analyze and
Community Food Webs
Food webs hold a central place in ecology. They describe which organisms feed on which others in natural habitats. This book describes recently discovered empirical regularities in real food webs: it proposes a novel theory unifying many of these regularities, as well as extensive empirical data. After a general introduction, reviewing the empirical and theoretical discoveries about food webs, the second portion of the book shows that community food webs obey several striking phenomenological regularities. Some of these unify, regardless of habitat. Others differentiate, showing that habitat significantly influences structure. The third portion of the book presents a theoretical analysis of ...
Bonney's Gynaecological Surgery
Firm favourite for gynaecological surgical practice since 1911, extensively revised by leading gynaecological surgeons Providing information on reconstructive surgery, anaesthesia, information technology and audit, complications and quality Focusing on the most commonly performed procedures with emphasis on evidence-based decision making and the increasing use of laparoscopy in diagnostic and surgical procedures
I Swear
I Swear: The Meaning of an Oath looks at how taking an oath may impact the obligations of the oath taker, and the perceptions and expectations of those around him. The book begins with Aeschylus - "It is not the oath that makes us believe the man, but the man the oath." The author explores whether Aeschylus was correct through stories of diverse and varied individuals who took an oath - doctor, lawyer, priest, journalist, CIA director, "made man," and president, to name a few. Most of the time, people are able to keep their oath. But what happens when the decision to keep an oath may result in an injustice, or a situation where others are hurt? What do your oaths mean to you, and what do they mean to those around you? Do societal pressures allow one to break his oath? What does your moral compass tell you to do when violating your oath is somehow the "right" thing to do, however wrong it is, because you're violating it?
