This ambitious study brings together three great thinkers of ancient and modern timesHusserl, Locke, and Platoin a careful analysis of the problem of knowledge, of what the unassisted human mind can know and how it may know what it does. I know of no other work that even attempts to do what this study does so well: to bring into respectful but critical dialogue with one another these three philosophers on the question what is knowledge? --Robert C. Bartlett, Behrakis Professor in Hellenic Political Studies, Boston College, USA Relativism, or the claim that it is possible that the appearances and opinions of each of us are correct for each of us, and hence that any view is as true as any other, has remained a continuing problem for philosophy and science for 2,500 years. Today, because of the widespread acceptance of relativism, the problem is greater than ever before. This book argues that Plato in fact solved this problem. In the first two chapters, by means of a study of Husserl and Locke, Davis shows that it is possible to return to and take seriously Platos treatment of this problem. The third chapter presents Platos solution to it. This book is distinctive in that it shows that a problem that has been thought to be present throughout the history of Western thought was in fact solved by Plato, and in that it shows that we can, beginning from our contemporary situation, return to Platos solution. Matthew K. Davis is former Dean and Director of Graduate Programs at St. John's College, Santa Fe, USA, where he has taught for twenty-five years.

Abstract
Nuclear disasters have severe and far-reaching consequences. Emergency managers and first responders from utility owners to local, state, and federal civil authorities and the Department of Defense (DoD) must be well prepared in order to rapidly mitigate the disaster and protect the public and environment from spreading damage. Given the high risks, modeling and simulation (M&S) plays a significant role in planning and training for the spectrum of derivate scenarios. Existing reactor models are largely legacy, stove-piped designs lacking interoperability between themselves and other M&S tools for emergency preparedness system evaluation and training. Unmanned systems present a growing area of technology promising significant improvement in response and mitigation. To bridge the gap between current and future models, we propose a conceptual model (CM) for integrating live, virtual, and constructive (LVC) models with nuclear disaster and mitigation models utilizing a system-of-systems (SoS) approach. The CM offers to synergistically enhance current reactor and dispersion simulations with intervening avatar and agent simulations. The SoS approach advances life cycle stages including concept exploration, system design, engineering, training, and mission rehearsal. Component subsystems of the CM are described along with an explanation of input/output requirements. A notional implementation is described. Finally, applications to analysis and training, an evaluation of the CM based on recently proposed criteria found in the literature, and suggestions for future research are discussed.

AbstractThe Protestant ethic has been depicted as declining inAmerica between 1870 and 1930, due to new consumer durables and less rewarding work. This study finds that the Protestant ethic did not so much decline as become transformed. The work ethic remained in force, while frugality weakened. This transformation is traced to three dynamic social forces: degradation in the quality of work due to industrialization, the decline of community with urbanization, and a dramatic increase in inequality. Consequently, social respect and social standing came increasingly to be sought through consumption, which became a proxy for hard work, entailing a weakening of asceticism.

While a considerable body of work concerning citizens' perceptions of risk for volcanic hazards has been done in the United States and New Zealand, no comparable study has focused on residents near Italy's two major volcanoes: Vesuvio and Etna. This survey study, involving 174 participants, focused on various measures of risk perception, feelings of personal vulnerability to the volcanic threat, and confidence in government officials' preparedness for potential eruptions. Although it was expected that due to a recent eruption of Etna, residents there would have higher levels of perceived risk than those at Vesuvio, findings mostly demonstrated the reverse. Additionally, residents living in the highest risk areas at Vesuvio demonstrated low levels of awareness concerning evacuation plans and low levels of confidence in the success of such plans.
