This book introduces the Design-Based Research (DBR) methodology to develop a pedagogy named Wiki-based Collaborative Process Writing Pedagogy (WCPWP). Through this, teachers can enrich their teaching knowledge and orchestrate collaborative writing activities by using Wiki to help primary school students with their Chinese writing. The results of this study have theoretical implications for applying Technological, Pedagogical, and Content Knowledge (TPACK) framework and design principles for implementing Wiki-based collaborative process writing in the Chinese context. It is an example of capitalizing on computer and Wiki technologies to support collaborative writing among upper primary school students in Mainland China.

The purpose of this book is to develop the foundations of potential theory and rational dynamics on the Berkovich projective line over an arbitrary complete, algebraically closed non-Archimedean field. In addition to providing a concrete and ``elementary'' introduction to Berkovich analytic spaces and to potential theory and rational iteration on the Berkovich line, the book contains applications to arithmetic geometry and arithmetic dynamics. A number of results in the book are new, and most have not previously appeared in book form. Three appendices--on analysis, $\mathbb{R}$-trees, and Berkovich's general theory of analytic spaces--are included to make the book as self-contained as possible. The authors first give a detailed description of the topological structure of the Berkovich projective line and then introduce the Hsia kernel, the fundamental kernel for potential theory. Using the theory of metrized graphs, they define a Laplacian operator on the Berkovich line and construct theories of capacities, harmonic and subharmonic functions, and Green's functions, all of which are strikingly similar to their classical complex counterparts. After developing a theory of multiplicities for rational functions, they give applications to non-Archimedean dynamics, including local and global equidistribution theorems, fixed point theorems, and Berkovich space analogues of many fundamental results from the classical Fatou-Julia theory of rational iteration. They illustrate the theory with concrete examples and exposit Rivera-Letelier's results concerning rational dynamics over the field of $p$-adic complex numbers. They also establish Berkovich space versions of arithmetic results such as the Fekete-Szego theorem and Bilu's equidistribution theorem.

Too many juvenile delinquents persist in their offending into adulthood. They constitute a major burden for individual victims, for businesses and the justice system, all contributing to the total cost of crime for society. Focusing on the transition between juvenile offending and adult crime, this book examines research based on Dutch, European and North-American studies on the persistence and discontinuity of offending between late adolescence and early adulthood. Presenting empirical studies showing why persistence or discontinuity take place, the book provides up-to-date information on preventive and remedial interventions to promote discontinuity of offending amongst young adults. From the same team who produced 'Tomorrow's Criminals', this book will be a valuable resource for criminologists, criminal justice professionals, psychologists, sociologists, and psychiatrists interested in juvenile and young adult offenders, as well as those interested in what makes career criminals and youth who reform.
