Sommario/riassunto |
|
Applications of semiconductor lasers with optical feedback systems are driving rapid developments in theoretical and experimental research. The very broad wavelength-gain-bandwidth of semiconductor lasers combined with frequency-filtered, strong optical feedback create the tunable, single frequency laser systems utilised in telecommunications, environmental sensing, measurement and control. Those with weak to moderate optical feedback lead to the chaotic semiconductor lasers of private communication. This resource illustrates the diversity of dynamic laser states and the technological applicat |

Sommario/riassunto |
|
Die Peacebuilding-Forschung und -Praxis sieht in der »Abwesenheit des Staates« gemeinhin eine zentrale Ursache für die Gewalt in Konfliktregionen - nicht nur in Kolumbien. Dass diese Annahme mindestens fraglich ist, zeigt Philipp Naucke in seiner historisch sensiblen Analyse der Formation staatlicher Strukturen und der Handlungsmöglichkeiten der kleinbäuerlichen Friedensgemeinde San José de Apartadó in der Konfliktregion Urabá. Seine detaillierte und einfühlsame Ethnographie paradoxer Begegnungen zwischen staatlichen Institutionen und Gemeindemitgliedern macht die Verantwortung eines »klientelisierten Staates« in der sozio-kulturellen Produktion des Gewaltkonfliktes sichtbar - und liefert besonders für den aktuellen Friedensprozess äußerst relevante Einsichten. |
