We have conducted an experimental study of V-type electromagnetically induced transparency in sodium. Its principles are elucidated by a simple model. Measurements show decreased fluorescence and absorption depending on the detuning of the driving and probe fields, which is in agreement with the results of numerical simulation.

Die Publikation enthält Beiträge zu theoretischen, lexikographischen und didaktischen Fragen von Kollokationen. Im Fokus stehen Kriterien der Delimitation der Mehrworteinheiten und die Fragen der didaktischen Relevanz von Kollokationen, ihrer Ermittlung und Vermittlung für die FS-Lerner. Die Beiträge zeigen die Notwendigkeit einer korpuslinguistischen methodischen und praktischen Grundkompetenz in der fremdsprachenphilologischen Ausbildung. In den didaktisch ausgerichteten Beiträgen wird analysiert, ob und in welcher Weise Kollokationen in den Lehrplänen behandelt werden und welche Bedeutung Kollokationen in nationalen und europäischen Dokumenten haben.

We show that, like singular cardinals, and weakly compact cardinals, Jensen's core model K for measures of order zero [4] calculates correctly the successors of Jónsson cardinals, assuming $O^{Sword}$ does not exist. Namely, if $\kappa$ is a Jónsson cardinal then $\kappa^+ = \kappa^{+K}$ , provided that there is no non-trivial elementary embedding $j:K \longrightarrow K$ . There are a number of related results in ZFC concerning $\cal{P}(\kappa)$ in V and inner models, for $\kappa$ a Jónsson or singular cardinal.

We prove that a form of the $Erd\H{o}s$ property (consistent with $V = L\lbrack H_{\omega_2}\rbrack$ and strictly weaker than the Weak Chang's Conjecture at ω1), together with Bounded Martin's Maximum implies that Woodin's principle $\psi_{AC}$ holds, and therefore 2ℵ0 = ℵ2. We also prove that $\psi_{AC}$ implies that every function $f: \omega_1 \rightarrow \omega_1$ is bounded by some canonical function on a club and use this to produce a model of the Bounded Semiproper Forcing Axiom in which Bounded Martin's Maximum (...) fails.

When can one say that a new theory is truer than the old one it contradicts, even though neither is absolutely true? We are primarily concerned with the case in which the conflicting theories offer answers to the same questions, and so we do not introduce considerations of "logical width". We propose that part of the new theory is truer than part of the old one when the former part gets right whatever the latter-part got right while the former does (...) not make any new mistakes. Pragmatic considerations will determine the relative importance of whatever new mistakes the new theory does make as a whole. To avoid artificial counterexamples, we restrict the parts compared to those that are "convex". A "convex" theory is one that holds in all cases intermediate between any two cases in which it holds.

Bioethics: 50 Puzzles, Problems, and Thought Experiments collects 50 cases—both real and imaginary—that have been, or should be, of special interest and importance to philosophical bioethics. Cases are collected together under topical headings in a natural order for an introductory course in bioethics. Each case is described in a few pages, which includes bioethical context, a concise narrative of the case itself, and a discussion of its importance, both for broader philosophical issues and for practical problems in clinical ethics and (...) health policy. Each entry also contains a brief, annotated, list of suggested readings. In addition to the classic cases in bioethics, the book contains discussion of cases that involve several emerging bioethical issues: especially, issues around disability, social justice, and the practice of medicine in a diverse and globalized world.

Richard Price argued for democratic institutions on the ground that each individual has a moral responsibility for the good government of his community. This assumption that political responsibilities are moral responsibilities was in turn derived from the belief that each individual has a continuous duty to create in his own personality and in his relations with his fellow men the conditions of the virtuous life. Popular political responsibility was thus defended by the extension of a rigorous moral athleticism into the (...) sphere of social arrangements. The dominating feature of this demand for comprehensive reform and reconstruction is the attempt to construe the moral life as a process in which the individual struggles to recreate himself in the light of his most mature conceptions. These conceptions, Price maintained, are determined rationally, and that they are so is presented in two different ways. Either as in the case of the principles of moral judgment they are held to be the objects of a rational intuition; or as in the defence of democratic institutions they are derived from an abstract construction of the demands of moral personality.
