ASIN: 068817180X Release Date: 2004-03-16 |
Book Description
Deep in the forest . . .
A bear sharpens her claws on a tree trunk. The scratched bark chips; a tiny hole forms. Timber beetles tunnel inside. The hole grows bigger and bigger.
In lyrical prose, Barbara Brenner reveals the fascinating happenings in one small place. She explains how, over many years, the rough hole transforms into a cozy hollow -- home to salamanders, tree frogs, a family of white-footed mice. Tom Leonard's absorbing illustrations take you beneath the bark to a hidden world. His warm, lifelike depictions of squirrels and bluebirds, snakes and spiders show the splendor that dwells in the most unexpected places.
So stop. Observe. Explore your natural world. If you look closely enough, you will surely find . . . one small place that is home for something.

Without Miracles: Universal Selection Theory and the Second Darwinian Revolution
Gary Cziko Manufacturer: Mit Pr ProductGroup: Book Binding: Hardcover Similar Items:
ASIN: 0262032325 |
Book Description
"The fish's streamlined shape reveals functional knowledge of the physical properties of water.... The deadly effectiveness of the cobra's venom shows useful knowledge of the physiology of its prey.... Indeed, knowledge itself may be broadly conceived as the fit of some aspect of an organism to some aspect of its environment, whether it be the fit of the butterfly's long siphon of a mouth to the flowers from which it feeds or the fit of the astrophysicist's theories to the structure of the universe. ... But how did such remarkable instances of fit arise? How did the animate world obtain its impressive knowledge of its surroundings? And how do organisms continue to acquire knowledge and thereby increase their fit during their lifetimes?"Customer Reviews:

Deceptively simple process generates beauty!.......2002-01-24
When a book can alter your perception and understanding of the world for the better you reread it. I'm currently on my third formal reading of this masterpiece. I go back to it often.
Cziko has brought to life the simple but powerful concept that Campbell called evolutionary epistemology: blind variation and selection. I use these concepts in everyday life (risk-taking, creativity, trade-off decision-making). Even if not useful, the concept would enegender admiration for its sheer beauty. The fact that it can be useful and fun is an added benefit.
A Must! But far from flawless..........2001-11-22
The central issue in the book is that just any kind of innovation, puzzle of fit, knowledge growth, or whatever you call it, can only be achieved through a process very much like biological evolution as accepted by the neo-darwinian paradigm: cumulative blind variation followed by the survival of the fittest. Cziko also shows how explanations for these puzzles of fit have evolved in all fields from providential explanations (like in the book of Genesis, where things happened to achieve a pourpose previously devised), through instructionist ones (like Lamarck's "Use and Disuse" plus "Inheritance of Acquired Characters", where the environment would "force" the individual creatures to change just in the right, successful way, and then the creatures would pass these changes on to their offsprings), and finally to selectionist ones (Darwin's Selection Theory). He says that only selectionist explanations can give truly "scientific" and "naturalistic" accounts for these fits, without recoursing to miraculous schemes. In short: Cziko brings us the good news that not only are we merely machines (like we have feared ever since the mechanical physics of Newton), but we are blind ones too!
The starting point of his reasoning is evolutionary biology, and Cziko's understanding of it seems to me too narrow-minded, with a strong bias toward the old notions of New-Darwinism. Consequently, his report and deductions on it are misinformative. Evolution was (and, to a large extent, still is) thought to be based on "variation and survival of the fittest". But in the past the view of the causes of these variations were believed to be basically errors: DNA damage by the environment, and failure of the organism to correct damages or to make precise copies of the DNA. It's been a long time now that this view has changed dramatically, and organisms, even as simple as bacteria, are now known (from before 1990) to possess amazing control over the ways and the contexts in which these variations happen. They can trigger DNA mutation under appropriate conditions (stress, threats to survival), and even control which areas of the genome will be subject to change. This renders organisms much more "smartly" interactive with the environment as might be expected from reading Cziko.
So, what Cziko did not tell about the process of antibody creation by B-Lynphocytes is that when they undergo somatic hypermutation to fine tune their antibody production to the antigen, this hypermutation is, first, triggered by the interaction with the very antigen, and second, it is far from blind: the mutation happens only in a very restricted area of the chromosome, changing only the areas of the antibody molecule that interact with the antigen (and not even the whole molecule!). So this is a very "thematic" kind of mutation-variation; maybe "short-sighted", but surely not "blind"!
When he comments on the phenomenon of "directed mutation", the strange capability of many procarionts (like bacteria) to seemingly direct their mutation to the desired result, he takes a rather cynical and slightly arrogant stand, apparently rejecting the existance of the phenomenon itself, even saying "But let us continue to imagine for a moment that a bacterium was able to change just those genes regulating metabolism in just the right way to allow for the digestion of a foreign sugar". It seems that he read only two research articles on this, and not quite well, and draw much of his attitude towards the phenomenon from his academic-environment prejudiced and uninformed criticism. By the time he was writing his book , directed mutation had been fully demonstrated by many researchers, and not only by Cairns. Actually, even as early as 1984, four years before Cairns revolutionary and controversial paper on it, J.A. Shapiro had already shown the phenomenon fully (Observations on the Formation of Clones Containing araB-lacZ cistrons fusions. Molecular & General Genetics 1984;194(1-2):79-80), only in a much more discreet maner. By 1995, a wealth of information was already available, from researchers like Shapiro and B.G. Hall, among others, and now even eukariotes (yeast) are known to perform "directed mutation" (Hall BG. Adaptive Mutagenesis: a Process that Generates Almost Exclusively Beneficial Mutations. Genetica 1998;102(103):109-125.). Strikingly, this process shows some resemblance to human B-lynphocyte somatic hypermutation!
When Cziko moves on to the other areas, scientific knowledge growth, etc, the already "short-sighted" (and not blind) variation seems to have undergone a surgical operation on its eye and starts to see almost sharply. Also, the second step, that is, the survival of the fittest (in biology, through killing the non-fit) seems to change to a true "selection" process (choosing one among many, by identifying its desirable qualities, which is quite different from "survival of the fittest"). Even Campbell and Pinker, which he defines as fully (or almost) selectionists, seem to turn to rather providential viewpoints, like "innativism" and "constraints", for triggering and orienting the variation, and guiding the selection, not succeding in solving Meno's providential dilema: "...if you don't already possess the knowledge you are looking for, how will you know when you have found it?"
Cziko, like many, wrongly equals "scientific" and "naturalistic" explanations to "mechanical" ones, and since our mechanistic view of nature is basically deterministic, he only sees lamarckism as an instructionist process, not a "freely-willed" one, failing to address vital phenomena like human consciouness and apparent free-will.
A brilliant tour de force.......2001-07-13
This book is well-written, clear, and immensely "instructive", causing me to modify a number of explanatory schemes in my own mind. I put it alongside the best of Dawkins, Dennett and Wilson. It should have a much wider readership than it apparently has.

An Introduction to Queueing Systems (Network and Systems Management)
Sanjay K. Bose Manufacturer: Springer ProductGroup: Book Binding: Hardcover Accessories: ASIN: 0306467348 |
Book Description
This volume accomplishes the unique task of providing the reader with the analytical fundamentals for both single queues and queueing networks while keeping the description simple enough so that the results may be directly used for modeling and analysis. A very wide range of single-queue models has been covered, while networks are analyzed through a very comprehensive set of approximation algorithms ready to apply in modeling. The text was honed through years of research and teaching, and is an excellent tool for engineers and students who wish to apply queueing methods to study the performance of systems.Customer Reviews:

An Introduction to Queueing Theory: and Matrix-Analytic Methods
L. Breuer , and Dieter Baum Manufacturer: Springer ProductGroup: Book Binding: Hardcover Similar Items: ASIN: 1402036302 |
Book Description
The textbook contains the records of a two-semester course on queueing theory, including an introduction to matrix-analytic methods. The course is directed to last year undergraduate and first year graduate students of applied probability and computer science, who have already completed an introduction to probability theory. Its purpose is to present material that is close enough to concrete queueing models and their applications, while providing a sound mathematical foundation for their analysis. A prominent part of the book will be devoted to matrix-analytic methods. This is a collection of approaches which extend the applicability of Markov renewal methods to queueing theory by introducing a finite number of auxiliary states. For the embedded Markov chains this leads to transition matrices in block form resembling the structure of classical models. Matrix-analytic methods have become quite popular in queueing theory during the last twenty years. The intention to include these in a students' introduction to queueing theory has been the main motivation for the authors to write the present book. Its aim is a presentation of the most important matrix-analytic concepts like phase-type distributions, Markovian arrival processes, the GI/PH/1 and BMAP/G/1 queues as well as QBDs and discrete time approaches.

Introduction to Stochastic Networks (Stochastic Modelling and Applied Probability)
Richard Serfozo Manufacturer: Springer ProductGroup: Book Binding: Hardcover ASIN: 0387987738 |
Book Description
In a stochastic network, such as those in computer/telecommunications and manufacturing, discrete units move among a network of stations where they are processed or served. Randomness may occur in the servicing and routing of units, and there may be queueing for services. This book describes several basic stochastic network processes, beginning with Jackson networks and ending with spatial queueing systems in which units, such as cellular phones, move in a space or region where they are served. The focus is on network processes that have tractable (closed-form) expressions for the equilibrium probability distribution of the numbers of units at the stations. These distributions yield network performance parameters such as expectations of throughputs, delays, costs, and travel times. The book is intended for graduate students and researchers in engineering, science and mathematics interested in the basics of stochastic networks that have been developed over the last twenty years. Assuming a graduate course in stochastic processes without measure theory, the emphasis is on multi-dimensional Markov processes. There is also some self-contained material on point processes involving real analysis. The book also contains rather complete introductions to reversible Markov processes, Palm probabilities for stationary systems, Little laws for queueing systems and space-time Poisson processes. This material is used in describing reversible networks, waiting times at stations, travel times and space-time flows in networks. Richard Serfozo received the Ph.D. degree in Industrial Engineering and Management Sciences at Northwestern University in 1969 and is currently Professor of Industrial and Systems Engineering at Georgia Institute of Technology. Prior to that he held positions in the Boeing Company, Syracuse University, and Bell Laboratories. He has held
