Criminal Law and Procedure

Probably the single most important development of the year came from the Joint Committee for the Revision of the Penal Code. That committee published its Tentative Draft No.1. The draft deals with general principles of liability, defenses, kidnapping and related crimes, sex crimes and arson. Other drafts are expected in the near future. It is hoped that the ultimate result will be a modernization of the Penal Code of 1872, which is badly in need of clarification and revision. Since 1872, there has never been a continuing and coordinated effort to develop a coherent and comprehensive code. Another important development is the new Journal of California Law Enforcement. The Journal, now in its second year, is published by the California Peace Officers\u27 Association for its members, and contains articles on such problems as black power, advising minors of their rights, the rights of arrested persons in general, some technical articles, as well as articles designed to improve police administration. Each issue includes a discussion of recent decisions

A review of the characteristics of nanoparticles in the urban atmosphere and the prospects for developing regulatory controls

The likely health and environmental implications associated with atmospheric nanoparticles have prompted considerable recent research activity. Knowledge of the characteristics of these particles has improved considerably due to an ever growing interest in the scientific community, though not yet sufficient to enable regulatory decision making on a particle number basis. This review synthesizes the existing knowledge of nanoparticles in the urban atmosphere, highlights recent advances in our understanding and discusses research priorities and emerging aspects of the subject. The article begins by describing the characteristics of the particles and in doing so treats their formation, chemical composition and number concentrations, as well as the role of removal mechanisms of various kinds. This is followed by an overview of emerging classes of nanoparticles (i.e. manufactured and bio-fuel derived), together with a brief discussion of other sources. The subsequent section provides a comprehensive review of the working principles, capabilities and limitations of the main classes of advanced instrumentation that are currently deployed to measure number and size distributions of nanoparticles in the atmosphere. A further section focuses on the dispersion modelling of nanoparticles and associated challenges. Recent toxicological and epidemiological studies are reviewed so as to highlight both current trends and the research needs relating to exposure to particles and the associated health implications. The review then addresses regulatory concerns by providing an historical perspective of recent developments together with the associated challenges involved in the control of airborne nanoparticle concentrations. The article concludes with a critical discussion of the topic areas covered. (C) 2010 Elsevier Ltd. All rights reserved
