City Networking in Europe Rescaling of the state and increased importance of cities in the multi-level system of governance
No full textThis thesis analyzes city networking from a rescaling perspective, highlighting the shift
from government towards non-hierarchical governance, a development shifting political
power between different scales. In its most institutionalized form, this development can
be found in the EU, where power is moved upwards to the supra-national level and
downwards to the sub-national level. As the EU system of governance is inherently multi-level, the international activity of cities can be understood as Europeanization of domestic practices, increasing the connections between the levels of governance and thus the multi-level character of the European political systems.
Previous research suggests explanations along two lines; city level variables and country level variables, such as domestic institutional relationships between national and sub-national levels. When using Regional Autonomy Index (RAI), World city index, and years of EU membership to measure cities’ international networking, and thus the interconnectedness between scales, the results point towards the country level variables having more explanatory value. Consequently, the level of networking seems to be conditioned by Europeanization in combination with national institutional relations measured by RAI. A longer history of membership, in combination with more
regional autonomy, limits the state ability to act as a gatekeeper and increases the networking. This shows higher adaptation to the multi-level system of governance in accordance with the Europeanization hypothesis
Quantum Computing in Solid State Systems
No full textThe aim of Quantum Computation in Solid State Systems is to report on recent theoretical and experimental results on the macroscopic quantum coherence of mesoscopic systems, as well as on solid state realization of qubits and quantum gates. Particular attention has been given to coherence effects in Josephson devices. Other solid state systems, including quantum dots, optical, ion, and spin devices which exhibit macroscopic quantum coherence are also discussed. Quantum Computation in Solid State Systems discusses experimental implementation of quantum computing and information processing devices, and in particular observations of quantum behavior in several solid state systems. On the theoretical side, the complementary expertise of the contributors provides models of the various structures in connection with the problem of minimizing decoherence

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
