TL;DR: In this article, the authors analyzed the Bologna process in higher education in Central and Eastern European (CEE) countries. But they focused on the convergence of national HE policies toward a common model.
Abstract: Contrary to many other areas, international and, in particular, European influences on national policymaking in higher education (HE) have remained limited. This picture, however, changed fundamentally from the late 1990s onward. In 1999, 29 countries signed the Bologna Declaration, denoting the start of the so-called Bologna Process. Thus, a collective supranational platform was developed to confront problem pressure, which has in turn fostered considerable domestic reforms. However, we still have limited knowledge on whether the Bologna Process has actually led to the convergence of national HE policies toward a common model. This article analyzes these questions by focusing on Central and Eastern European (CEE) countries. Because of its tumultuous and inconsistent path of development and the sheer magnitude of the current reform processes, CEE HE stands out as a particularly worthwhile object of analysis for scholars interested in policy convergence as well as policy legacies and path dependencies.

TL;DR: A direct correlation existed between the myosin heavy chain composition and the histochemical mATPase staining and was especially evident in the C fiber population with its variable HCI/HCIIa ratio.
Abstract: Combined histochemical and biochemical analyses were performed on single fibers of rabbit soleus muscle. Histochemically, four fiber types (I, IC, IIC, IIA) were defined. Of these, types I and IIA were separate, histochemically homogeneous groups. A heterogeneous C fiber population exhibited a continuum of staining intensities between types I and IIA. Microelectrophoretic analyses of specific, histochemically defined fibers revealed that type I fibers contained exclusively HCI, whereas type IIA fibers contained only HCIIa. The C fibers were characterized by the coexistence of both heavy chains in varying ratios, type HC with a predominance of HCI and type IIC with a predominance of HCIIa. A direct correlation existed between the myosin heavy chain composition and the histochemical mATPase staining and was especially evident in the C fiber population with its variable HCI/HCIIa ratio. This correlation did not apply to the myosin light chain complement.

TL;DR: In this article, the effect of preference similarity is absorbed by institutional, relational, and social opportunity structures in the German toxic chemicals policy domain and different types of information exchange operate in complementary, but not necessarily congruent, ways.
Abstract: Information exchange in policy networks is usually attributed to preference similarity, influence reputation, social trust, and institutional actor roles. We suggest that political opportunity structures and transaction costs play another crucial role and estimate a rich statistical network model on tie formation in the German toxic chemicals policy domain. The results indicate that the effect of preference similarity is absorbed by institutional, relational, and social opportunity structures. Political actors choose contacts who minimize transaction costs while maximizing outreach and information. We also find that different types of information exchange operate in complementary, but not necessarily congruent, ways.

TL;DR: The experimental observation of the rate which approaches this linear nonclassical behavior of a three level atom driven with squeezed vacuum via a two-photon excitation process is presented.
Abstract: The recent development of frequency tunable nonclassical light sources have opened up possibilities for performing spectroscopy with nonclassical light. Various different avenues in this new field can be naturally organized in two groups: atomic measurements with the sensitivity beyond the standard quantum limit and fundamental alterations of atomic radiative processes due to nonclassical nature of the e.-m. field. While the number of theoretical predictions has been rapidly growing for the last decade[1] the experimental progress has been achieved only recently and so far only in the first group: sub-shot-noise spectroscopy[2,3]. We report here the first experiment that belongs to the second group: driving multilevel atoms with nonclassical light. More precisely we report the observation of the fundamental nonclassical behavior of a three level atom driven with squeezed vacuum via a two-photon excitation process. It is well known that the rate of the two-photon excitation Г2 for thermal or coherent light is proportional to the square of the intensity of the excitation field (only weak excitation is considered here, i.e., no saturation effects are involved). By contrast, the manifestly quantum correlations of squeezed vacuum can enhance this rate such that it becomes a linear function of intensity [4]. We present here the experimental observation of the rate which approaches this linear nonclassical behavior.
