Quantum Coherence in a Single Ion due to strong Excitation of a metastable Transition

We consider pump-probe spectroscopy of a single ion with a highly metastable (probe) clock transition which is monitored by using the quantum jump technique. For a weak clock laser we obtain the well known Autler-Townes splitting. For stronger powers of the clock laser we demonstrate the transition to a new regime. The two regimes are distinguished by the transition of two complex eigenvalues to purely imaginary ones which can be very different in magnitude. The transition is controlled by the power of the clock laser. For pump on resonance we present simple analytical expressions for various linewidths and line positions.Comment: 6 figures. accepted for publication in PR

Fish remains, mostly otoliths, from the non-marine early Miocene of Otago, New Zealand

Fish remains described from the early Miocene lacustrine Bannockburn Formation of Central Otago, New Zealand, consist of several thousand otoliths and one skeleton plus another disintegrated skull. One species, Mataichthys bictenatus Schwarzhans, Scofield, Tennyson, and T. Worthy gen. et sp. nov., an eleotrid, is established on a skeleton with otoliths in situ. The soft embedding rock and delicate, three−dimensionally preserved fish bones were studied by CT−scanning technology rather than physical preparation, except where needed to extract the otolith. Fourteen species of fishes are described, 12 new to science and two in open nomenclature, representing the families Galaxiidae (Galaxias angustiventris, G. bobmcdowalli, G. brevicauda, G. papilionis, G. parvirostris, G. tabidus), Retropinnidae (Prototroctes modestus, P. vertex), and Eleotridae (Mataichthys bictenatus, M. procerus, M. rhinoceros, M. taurinus). These findings prove that most of the current endemic New Zealand/southern Australia freshwater fish fauna was firmly established in New Zealand as early as 19–16 Ma ago. Most fish species indicate the presence of large fishes, in some cases larger than Recent species of related taxa, for instance in the eleotrid genus Mataichthys when compared to the extant Gobiomorphus. The finding of a few otoliths from marine fishes corroborates the age determination of the Bannockburn Formation as the Altonian stage of the New Zealand marine Tertiary stratigraphy.Werner Schwarzhans, R.

Adoption of managerial ideologies in Finnish academic management education 1960-2007

The article analyses when and how different management paradigms have been adopted for teaching, in the subject of organization and management, by examining the curricula and study guides of the eight main business schools in Finland.The data was analysed in three ways: (1) the analysis of all the reading lists in curricula and study guides, (2) the analyses of subject descriptions in the study guides and (3) the analysis of individual course descriptions in the study guides.Theoretically, the study draws on the literature on German-style and American-style business schools, and on the literature on management paradigms and their dissemination.Our findings indicate that there are differences in the adoption of different management paradigms in management education in German-style and American-style business schools in Finland. For example, between 1980 and 1995, the most commonly used paradigm in teaching in German-style schools was the human relations paradigm, while in American-style schools the most popular paradigm was structural analysis.The results suggest that different traditions in arranging higher management education may have an impact on the content of teaching.This provides an interesting point of departure for investigating the contents of management education in other countries, too

Discourse studies of scientific popularisation: questioning the boundaries.

This article critiques the `dominant view' of the popularization of science that takes it as a one-way process of simplification, one in which scientific articles are the originals of knowledge that is then debased by translation for a public that is ignorant of such matters, a blank slate. Recent work is surveyed in several disciplines that questions the boundaries of scientific discourse and genres of popularization: who the actors are, how the discourses interact, what modes are involved, and what is communicated. Implications are drawn from these studies for discourse analysis
