Coffeeshops are the most famous example of Dutch tolerance. But in fact, these cannabis distributors are highly regulated. Coffeeshops are permitted to break the law, but not the rules. On the premises, there cannot be minors, hard drugs or more than 500 grams. Nor can a coffeeshop advertise, cause nuisance or sell over five grams to a person in a day. These rules are enforced by surprise police checks, with violation punishable by closure. In Grey Area, Scott Jacques examines the regulations with a huge stash of data, which he collected during two years of fieldwork in Amsterdam. How do coffeeshop owners and staff obey the rules? How are the rules broken? Why so? To what effect? The stories and statistics show that order in the midst of smoke is key to Dutch drug policy, vaporising the idea that prohibition is better than regulation. Grey Area is a timely contribution in light of the blazing reform to cannabis policy worldwide. Praise for Grey Area ‘This book is original and highly topical. Logical and well structured, the discussion is firmly located in a large body of contemporary theory. The writing style is conversational, open and accessible. The quality, amount and depth of the empirical work that Jacques has undertaken made me feel that I was there, visiting the coffeeshops with him. Rarely have I seen something as careful and detailed as this work.’ Ronald V. Clarke, Rutgers University, USA 'This book examines the intricacies of operating between law and rules in Amsterdam coffeeshops. Based on an extensive fieldwork, it is arguably the most comprehensive criminological analysis of the issue to date. This is an important work, from an excellent writer, that I warmly recommend to both students and researchers.’ Kim Møller, Malmö University, Sweden

Thoroughly revised, this third edition focuses on modern techniques used to generate synthetic three-dimensional images in a fraction of a second. With the advent of programmable shaders, a wide variety of new algorithms have arisen and evolved over the past few years. This edition discusses current, practical rendering methods used in games and other applications. It also presents a solid theoretical framework and relevant mathematics for the field of interactive computer graphics, all in an approachable style. The authors have made the figures used in the book available for download for fair use.:Download Figures. Reviews Rendering has been a required reference for professional graphics practitioners for nearly a decade.

Martin Gardner's Mathematical Games columns in Scientific American inspired and entertained several generations of mathematicians and scientists. Gardner in his crystal-clear prose illuminated corners of mathematics, especially recreational mathematics, that most people had no idea existed. His playful spirit and inquisitive nature invite the reader into an exploration of beautiful mathematical ideas along with him. These columns were both a revelation and a gift when he wrote them; no one--before Gardner--had written about mathematics like this. They continue to be a marvel. This volume was originally published in 1989 and contains columns from published 1976-1978. This 1997 MAA edition contains three new columns written specifically for this volume including the resurrection of the lamented Dr. Matrix.

Rebecca M. Warner’s bestselling Applied Statistics: From Bivariate Through Multivariate Techniques has been split into two volumes for ease of use over a two-course sequence. Applied Statistics I: Basic Bivariate Techniques, Third Edition is an introductory statistics text based on chapters from the first half of the original book. The author′s contemporary approach reflects current thinking in the field, with its coverage of the "new statistics" and reproducibility in research. Her in-depth presentation of introductory statistics follows a consistent chapter format, includes some simple hand-calculations along with detailed instructions for SPSS, and helps students understand statistics in the context of real-world research through interesting examples. Datasets are provided on an accompanying website.
