This book addresses the fundamental changes that the Italian public utilities sector has undergone in the last two decades. Since the late 1990s, liberalisation and privatisation have replaced state-owned monopolies at both the national and local level, new technologies have created a broad range of new opportunities for power generation and distribution, and a redesigned public policy agenda has brought to the fore a whole set of new priorities. In this fast-changing environment, firms have redrawn their strategies, redesigned their business architectures and models, invested in infrastructure and R&D, taken advantage of growth opportunities at home and abroad, opened up their ownership structure, revised their offerings, and developed a new approach to customers. As a result, a radically altered market structure has emerged. As the sector tackles the overriding challenge of sustainability and energy transition, the book takes stock of such past and ongoing developments throughthe direct testimonies of various stakeholders: the companies in the energy, water, and waste management sectors that are at the forefront of this sweeping transformation; regulators; financial partners; and management consulting firms. The diversity of perspectives and wealth of information presented make this book a valuable resource for anyone wanting to grasp the direction, intensity and causes of change, as well as the nature of the challenges that lie ahead.This work has been prepared as part of the research activities of the Observatory on Alliances and Strategies in the Pan-European Utility Market, one of Agici¿s Research and Advisory units.

This book commemorates the scientific contributions of distinguished statistician, Andrei Yakovlev. It reflects upon Dr. Yakovlev¿s many research interests including stochastic modeling and the analysis of micro-array data, and throughout the book it emphasizes applications of the theory in biology, medicine and public health. The contributions to this volume are divided into two parts. Part A consists of original research articles, which can be roughly grouped into four thematic areas: (i) branching processes, especially as models for cell kinetics, (ii) multiple testing issues as they arise in the analysis of biologic data, (iii) applications of mathematical models and of new inferential techniques in epidemiology, and (iv) contributions to statistical methodology, with an emphasis on the modeling and analysis of survival time data. Part B consists of methodological research reported as a short communication, ending with some personal reflections on researchfields associated with Andrei and on his approach to science. The Appendix contains an abbreviated vitae and a list of Andrei¿s publications, complete as far as we know. The contributions in this book are written by Dr. Yakovlev¿s collaborators and notable statisticians including former presidents of the Institute of Mathematical Statistics and of the Statistics Section of the AAAS. Dr. Yakovlev¿s research appeared in four books and almost 200 scientific papers, in mathematics, statistics, biomathematics and biology journals. Ultimately this book offers a tribute to Dr. Yakovlev¿s work and recognizes the legacy of his contributions in the biostatistics community.
