In most countries in the world, school education is the business of the state. Even if forms and functions differ, the imparting of elementary knowledge is universally regarded as a public function. Yet this is neither self-evident nor self-explanatory. The degree of involvement of state agencies in the supervision, financing and organization of the school system sometimes varies so much that the usual assumption of a common understanding of 'the state' seems to be an illusion. Making international comparisons and focusing strongly on the historical conditions of the current form of state...

Summarizing our present knowledge of the structures and chemistry of small organic cations in the gas phase, Assigning Structures to Ions in Mass Spectrometry presents the methods necessary for determining gas-phase ion structures. It is a comprehensive resource of background material that is essential for the interpretation and understanding of organic mass spectra.
Following a historical introduction of chief discoveries, the book surveys current experimental methods for ion production and separation as well as those designed to reveal qualitative and quantitative aspects of gas-phase...

Petri Nets were defined for the study of discrete events systems and later extended for many purposes including dependability assessment. In our knowledge, no book deals specifically with the use of different type of PN to dependability. We propose in addition to bring a focus on the adequacy of Petri net types to the study of various problems related to dependability such as risk analysis and probabilistic assessment.

In the first part, the basic models of PN and some useful extensions are briefly recalled. In the second part, the PN are used as a formal model to describe the...

The transition from the Paleocene to the Eocene Epoch--approximately 55 million years ago--represents a critical moment in the earth's history, when the warmest climatic episode of the Cenozoic era occurred. This sudden global warming resulted in major turnovers among marine and terrestrial organisms. Although this episode has become one of the most popular areas of research in the geologic sciences in the past decade, there has not yet been a work that brings together the profusion of new results in one volume. This book offers by far the most comprehensive source of data on a critically...
