Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos.

Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

The introductory chapter of this book presents the concepts of the bene?ts inherent in the study of comparative approach for an effective counterterrorism response on the local law enforcement level and overviews the inception of the project. Throughout the twentieth century and into the twenty-?rst century, especially after the events of September 11, 2001, the legitimacy of law enforcement practices has been cited as a major concern for international criminal justice. As policing pr- titioners and scholars throughout the world shifted focus from a traditional reactive, crime control stance to the need for accountability mechanisms to ensure the s- port of citizenry in combating crime and terrorism, the democratization of policing was seen as the best mechanism for achieving long-term gains in public order at the same time as protecting human rights. While the need to maintain human rights remains an important issue, balancing these concerns with the important public safety interests of societies is paramount.

The intense current interest in the development of solar energy as a viable energy alternative comes as no surprise in view of the widespread awareness of impending world-wide energy shortages. After all, the magnitude of energy available from the sun is impressive, its diffuseness and intermittent nature notwithstanding. The fact that, as a source, it represents a constant and inex haustible supply of energy is alluring. The fact that most solar application schemes are nonpolluting in nature is an attractive bonus. In spite of these impressive attributes, research and development in the area of solar energy is in its infancy, owing largely to the prior lack of any need to exploit such diffuse sources. Indeed efforts in this area have traditionally been within the province of solid-state physics and engineering. The problems associated with efficient light harvesting and storage, however, are not simply technological ones. Effec tive solutions to these problems appear to lie beyond the current forefront of the chemical sciences. Consequently input fr9m scientists previously engaged in fundamental chemistry has begun to emerge. Thus many of the contributions in this volume represent input from research groups with a relatively short history of involvement in solar energy. On the other hand, the long-standing and perceptive commitment of Professor Melvin Calvin to research involving solar energy represents the other extreme. This volume covers a variety of approaches to the problem of efficiently converting and storing solar energy."
