Highest Energy Cosmic Rays and results from the HiRes Experiment

The status of the field of ultrahigh energy cosmic rays is summarized, from the point of view of the latest results of the High Resolution Fly's Eye (HiRes) Experiment. HiRes results are presented, and compared with those of the Akeno Giant Air Shower Array (AGASA), plus the Telescope Array and Pierre Auger experiments. The HiRes measurements of the cosmic ray spectrum, and the observation of the GZK cutoff are presented. HiRes results on composition, searches for anisotropy, measurement of the proton-air total cross section, and shapes of shower profiles are presented.Comment: 31 pages, 18 figures, submitted to Journal of Physics

Regulation Theories in Retrospect and Prospect.

This chapter critically assesses the regulation approach to the critique of political economy. It starts with the theoretical background to regulation theories; moves on to compare the main approaches and their various fields of application; and then offers some methodological and epistemological criticisms of the leading schools. Then come some more general methodological remarks on the object and subject of regulation and some specific comments on one of the weakest areas of regulation theory - its account of the state. Thus this chapter focuses on methodology and general theory rather than empirical analysis
