Between 1800 and 1900 the Industrial Revolution swept the United States. Behind this revolution were changes in business organization and advancement in science and technology. This book is concerned with the interaction of these social forces. It demonstrates when and for what reasons the introduction of new manufacturing led to business risks and losses. The study is based on the records of technological innovation in methods of producing iron and steel, in textile machinery, in machine tools, and in electric power equipment.

This volume describes the findings of a longitudinal, birth cohort study of juvenile delinquency in Puerto Rico. Carried out under the auspices of the Puerto Rican Senate's Special Crime Commission, the book represents a new type of birth cohort study, based on the classic work done in Philadelphia. The authors have traced Puerto Rican children born in 1970, both male and female, through the greater San Juan police departments, charting the incidence of delinquency and the number of recurring offenders. These findings are compared to the Philadelphia studies of 1945 and 1958.

The book begins its examination with a discussion of the background for the current study. Literature on juvenile delinquency in Puerto Rico is reviewed, official statistics are cited, and a discussion of the birth cohort and the importance of longitudinal studies is provided. Chapter 2 addresses the prevalence of delinquency, and chapter 3 details its incidence, severity, and types of offenses. Succeeding chapters cover such areas as age and delinquency, delinquent recidivism, and police and court dispositions. The volume concludes with a section on cohort comparisons, a summary of the findings, and some policy implications and suggestions for legislation. A group of appendices is also included. This work will be an important addition for courses in criminology and sociology, as well as a valuable resource for college and university libraries.

This book introduces the theory of stochastic processes with applications taken from physics and finance. Fundamental concepts like the random walk or Brownian motion but also Levy-stable distributions are discussed. Applications are selected to show the interdisciplinary character of the concepts and methods. In the second edition of the book a discussion of extreme events ranging from their mathematical definition to their importance for financial crashes was included. The exposition of basic notions of probability theory and the Brownian motion problem as well as the relation between conservative diffusion processes and quantum mechanics is expanded. The second edition also enlarges the treatment of financial markets. Beyond a presentation of geometric Brownian motion and the Black-Scholes approach to option pricing as well as the econophysics analysis of the stylized facts of financial markets, an introduction to agent based modeling approaches is given.
