Discusses how many people the earth can support in terms of economic, physical, and environmental aspects.
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.
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?
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
Throughout the West, democracy is under fire. "Government is part of the problem, not the solution" is a common refrain. As the tasks of the state become more complex and the size of polities larger, the institutional forms of liberal democracy developed in the 19th century seem increasingly unable to cope. Rather than seeking to deepen the democratic character of politics, much energy in recent years has been directed as reducing the role of politics altogether. In Associations and Democracy, Joshua Cohen and Joel Rogers advance an innovative scheme for rejuvenating the democratic state. Their proposal involves the strengthening of secondary associations, organizations like unions, works co...
