While some of the material may be subject to revisal or correction, the basic aim and structure of the book presents a powerful approach to understanding the nature of human consciousness. In particular the symbolic aspects of cognition.
To balance the "hardwired" picture created by the authors' use of concepts like "neurognostic structures", I recommend the work of Gerald Edelman (Neural Darwinism, Remembered Present, etc...) as a counterpoint. This would help provide a balance relation between genetic and epigenetic aspects. Somewhere between the two sets of ideas a rich scientific and biologically meaningful framework emerges.
If you are interested in the biological nature of consciousness and it's relation to culture, this is a must read book.

This book focuses on the impact of crack cocaine in three eastern cities -- North Philadelphia, Harlem, and Red Hook, New Jersey.
Richards seems to have none of the fear that would stop most people, because his pictures bring a viewer over the comfort line to become shocking. The scenes exceed imagination. In fact, one of his pictures in this book was challenged for its authenticity because it seemed almost too perfect... In it, a women pauses to look at her John, her hands on his zipper, with her young child watching her. On a wall behind her, a picture of Martin Luther King, Jr. is displayed. Some black political leaders saw this picture and insisted that Richards must have set it up. He could only assert that he was truthful in his portrayal.
Truth is always stranger than fiction. This might be photojournalism's answer to magical realism: there is a wickedness and abandon to this world. The cover picture is another example -- the photograph shows an addict holding a syringe in his mouth. His eyes gleam in a way that suggests the insanity in the spirit of this individual.
Richards is for the most part a photographer who works inside America. Some domestic photographers lament that all of the best photographs are made in wars, and that the situations in our home communities preclude us from being able to make great pictures. Eugene Richards shows how this is false. He takes horrifying pictures in Long Island, in Philadelphia, in West Virginia, in Kansas City.

However there is not much on NP completeness, since this book was published in 1976. For a more to date version of events in combinatorial optimisation one might want to look at Papadimitriou and Steglitz's book on combinatorial optimisation (quite old too, considering this was published in 1982), Ahuja, Magnanti and Orlin's book on Network algorithms, Hochbaum's book on approximation algorithms and Cook, Cunnigham,Pulleyblank and Schrijver's book on combinatorial optimisation (listed in the order they were published).
Lawler's book is extremely well written and I am delighted that this book is now published by Dover, and hence easily affordable.

In a clear, concise, format the authors have provided all the basic information essential to preparing individuals for a career which requires knowledge, skill and professionalism in all aspects.
Beginning immediately in chapter 1 "Case Initiation", the reader will be taken into the complex, demanding world of security investigation, and taught step-by-step the skills required. An easy to follow, easy to refer back to, outline style format will be appreciated as the book continues, covering topics such as surveillance, interviewing techniques and evidence.
Set-in boxes, charts, diagrams and sample reports, (this last undoubtedly drawn from author Celano's 20 year career with the N.Y. Police Department) are what sets this book apart from other texts on security investigations, making it a number one choice for use in the field.
Highly recommended!
