Recurrence Plot Based Measures of Complexity and its Application to Heart Rate Variability Data
The knowledge of transitions between regular, laminar or chaotic behavior is
essential to understand the underlying mechanisms behind complex systems. While
several linear approaches are often insufficient to describe such processes,
there are several nonlinear methods which however require rather long time
observations. To overcome these difficulties, we propose measures of complexity
based on vertical structures in recurrence plots and apply them to the logistic
map as well as to heart rate variability data. For the logistic map these
measures enable us not only to detect transitions between chaotic and periodic
states, but also to identify laminar states, i.e. chaos-chaos transitions. The
traditional recurrence quantification analysis fails to detect the latter
transitions. Applying our new measures to the heart rate variability data, we
are able to detect and quantify the laminar phases before a life-threatening
cardiac arrhythmia occurs thereby facilitating a prediction of such an event.
Our findings could be of importance for the therapy of malignant cardiac
arrhythmias
The evolution of private provision in urban drinking water: New geographies, institutional ambiguity and the need for political economy
Empirical research paints a dynamic picture of the evolution of private provision in urban drinking water. A second wave of privatisation is clustered in a key group of countries, distinguished by the rise of new domestic private and quasi-private providers. This is, however, taking place in the presence of a counter-dynamic of remunicipalisation. In response to the complexity in provision arrangements revealed, three case studies are used to illustrate how different power balance configurations in the state-society-capital complex inform particular institutional arrangements. In Germany, civil society pressure challenged private capital resulting in the reinstatement of municipal control in Berlin, but at high long-term costs. In Russia, disempowered civil society has watched as the ruling regime exploits the support of international public agencies and foreign investors, while carefully safeguarding the interests of domestic private capital. In China, different levels of the state have promoted quasi-state actors into global corporations, managing the entry of international capital in order to bolster domestic support for desired political reforms. Public responsibility, and equally the re-assertion of public control after a period of private provision, may not in itself secure net social benefit where the right of capital to profit is put before broader social considerations

Entlastung der Umwelt und des Verkehrs durch regionale Wirtschaftskreislaeufe
Transport performance has outpaced the growth of real GDP in recent decades. By 20015 a further increase in transport performance of between 50% and 79% over 1997 is forecast. Strengthening regional economies is one way of structurally countering the trend of over-proportionally rising traffic flows in the long term. The study examines the links between economic and transport development at the regional level. Options are also presented for promoting regional economies, thereby decreasing the volume of inter-regional transport. (orig.)Die Verkehrsleistung nahm in den letzten Jahrzehnten staerker zu als das reale Bruttoinlandsprodukt. Gegenueber 1997 wird bis zum Jahr 2015 eine weitere Steigerung der Verkehrsleistung auf der Strasse von 50% und 79% prognostiziert. Eine Staerkung regionaler Wirtschaftskreislaeufe wird als Mittel gesehen, um dem Trend ueberproportional steigender Verkehrsstroeme strukturell und langfristig entgegenzuwirken. In der Studie wurden die Zusammenhaenge zwischen wirtschaftlicher und verkehrlicher Entwicklung auf regionaler Ebene erforscht. Zudem werden Moeglichkeiten eroertert, die regionale Wirtschaftskreislaeufe foerdern und so das Volumen interregionaler Transporte verringern.

Gesamtwirtschaftliche Beurteilung von CO_2 Minderungsstrategien
In Germany, a comprehensive pogramme was launched in the past years for the purpose of achieving a 25 percent reduction in carbon dioxide emissions by 2005 as compared to the reference year 1990. The catalogue of measures ranges from legal regulations to economic incentives and to information and consulting. This investigation investigates the reduction effects to be expected from these measures as well as the sectoral and general economic cost effects. The interdependences between clean air policy on the one hand and sectoral and general economic goals like acceptable economic growth, stable prices and a level foreign trade balance are to be defined. (orig./RHM)In Deutschland wurde in den letzten Jahren ein umfassendes Minderungsprogramm auf den Weg gebracht, mit dem eine Verringerung der CO_2-Emissionen bis zum Jahr 2005 gegenueber 1990 um 25 vH erreicht werden soll; das Massnahmenbuendel reicht von ordnungsrechtlichen Ge- und Verboten ueber oekonomische Anreize bis hin zu Information und Aufklaerung. Die vorliegende Untersuchung stellt die mit diesem Massnahmenkatalog verbundenen Reduktionswirkungen wie auch die sektoralen und gesamtwirtschaftlichen Kostenimpulse im Detail dar. Ziel ist es, den Zusammenhang zwischen Klimaschutzpolitik einerseits, sektoralen und gesamtwirtschaftlichen Zielen wie angemessenes Wirtschaftswachstum, stabiles Preisniveau oder aussenwirtschaftliches Gleichgewicht andererseits sichtbar zu machen.
