So Many Zebras, So Little Time


Book Description

Force ratios are an important variable in warfare and in nature. On the Serengeti, large zebra herds are hunted by small prides of lions. But with their overwhelming majority, why don¿t the zebras unite and attack the lions? Ecological interactions between predators and their prey are complex. The mathematics underlying different types of survival strategies for attacker and evader have been worked out by ecologists. While not a perfect metaphor, these quantitative ecology models greatly resemble behavioral interactions during counterinsurgency operations. This paper suggests a framework for other researchers to adapt and expand. Indeed, many of the models discussed are common to both ecologists and economists.




Why Zebras Don't Get Ulcers


Book Description

Renowned primatologist Robert Sapolsky offers a completely revised and updated edition of his most popular work, with over 225,000 copies in print Now in a third edition, Robert M. Sapolsky's acclaimed and successful Why Zebras Don't Get Ulcers features new chapters on how stress affects sleep and addiction, as well as new insights into anxiety and personality disorder and the impact of spirituality on managing stress. As Sapolsky explains, most of us do not lie awake at night worrying about whether we have leprosy or malaria. Instead, the diseases we fear-and the ones that plague us now-are illnesses brought on by the slow accumulation of damage, such as heart disease and cancer. When we worry or experience stress, our body turns on the same physiological responses that an animal's does, but we do not resolve conflict in the same way-through fighting or fleeing. Over time, this activation of a stress response makes us literally sick. Combining cutting-edge research with a healthy dose of good humor and practical advice, Why Zebras Don't Get Ulcers explains how prolonged stress causes or intensifies a range of physical and mental afflictions, including depression, ulcers, colitis, heart disease, and more. It also provides essential guidance to controlling our stress responses. This new edition promises to be the most comprehensive and engaging one yet.




So Many Zebras, So Little Time


Book Description

Force ratios are an important variable in warfare and in nature. On the Serengeti, large zebra herds are constantly hunted by small prides of lions. But with their overwhelming majority, why don't the zebras unite and attack the lions? Hooves can be as deadly as claws when used correctly. And conversely, if the lions are such effective predators, why are there so many zebras? Ecological interactions between predators and their prey are complex. Sometimes the few prey on the many; picture a whale devouring thousands of docile microorganisms. And sometimes the many prey on the few, as with killer bees attacking an unsuspecting person. During the past century, the mathematics underlying different types of survival strategies for attacker and evader have been worked out by ecologists, and we now have a fairly good understanding of such relationships. While not a perfect metaphor, it is striking that these quantitative ecology models greatly resemble behavioral interactions during counterinsurgency operations. While a predator-prey model alone may be too simplistic to fully describe counterinsurgency, there are more detailed ecological models of competition that better capture the essence of the problem. The purpose of this paper is not to provide definitive solutions, but to suggest a framework for other researchers to adapt and expand upon. Indeed, many of the models discussed are common to both ecologists and economists. The goals of both types of modeling are similar: maximizing profits in terms of food or money at the least risk death or bankruptcy. From our preliminary work on the possible applications of ecology to counterinsurgency, we hope that others more adept at the use of these quantitative models will make significant contributions to the area of predictive ability in combating terrorism and understanding unconventional warfare.




Zebra Stripes


Book Description

Why do zebras have stripes? Popular explanations range from camouflage to confusion of predators, social facilitation, and even temperature regulation. It is a challenge to test these proposals on large animals living in the wild, but using a combination of careful observations, simple field experiments, comparative information, and logic, Caro concludes that black-and-white stripes are an adaptation to thwart biting fly attack.

On Beyond Zebra!


Book Description

If you think the alphabet stops with Z, you are wrong. So wrong. Leave it to Conrad Cornelius o'Donald o'Dell (with a little help from Dr. Seuss) to create an entirely new alphabet beginning with Z! This rhyming picture book introduces twenty new letters and the creatures that one can spell with them. Discover (and spell) such wonderfully Seussian creations as the Yuzz-a-ma-Tuzz and the High Gargel-orum. Readers young and old will be giggling from beginning to end . . . or should we say, from Yuzz to Hi!




The Zebra Who Ran Too Fast

Simulation and Modeling of Systems of Systems


Book Description

Systems engineering is the design of a complex interconnection of many elements (a system) to maximize a specific measure of system performance. It consists of two parts: modeling, in which each element of the system and its performance criteria are described; and optimization in which adjustable elements are tailored to allow peak performance. Systems engineering is applied to vast numbers of problems in industry and the military. An example of systems engineering at work is the control of the timing of thousands of city traffic lights to maximize traffic flow. The complex and intricate field of electronics and computers is perfectly suited for systems engineering analysis and in turn, advances in communications and computer technology have made more advanced systems engineering problems solvable. Thus, the two areas fed off of one another. This book is a basic introduction to the use of models and methods in the engineering design of systems. It is aimed at students as well as practicing engineers. The concept of the "systems of systems" is discussed extensively, after a critical comparison of the different definitions and a range of various practical illustrations. It also provides key answers as to what a system of systems is and how its complexity can be mastered.
