Corporate Lighting: Methoden und Techniken der Architekturbeleuchtung zur Markenkommunikation

Die Arbeit analysiert Architekturbeleuchtung als Element zur Markenkommunikation. Die Beleuchtung wird als Nachricht eines Senders verstanden, die sich auf das Erscheinungsbild von Architektur auswirkt. Mit Experimenten und Fallstudien werden die Effekte der Beleuchtung auf das Erscheinungsbild für einen neutralen Raum sowie für Innenräume und Außenräume im Bereich Einzelhandel und Dienstleistung untersucht. Bei der Beleuchtung dienen Beleuchtungsstärke, Leuchtdichteverteilung sowie Lichtspektrum und Dynamik als unabhängige Variablen. Für das Erscheinungsbild als abhängige Variable wird ein Modell zur Markenpersönlichkeit mit den vier Faktoren Temperament, Kompetenz, Attraktivität und Natürlichkeit herangezogen sowie ein soziologisches Modell mit den zwei Faktoren Stil und Preis für soziale Milieus. Die Experimente erfolgen im realen Raum wie auch mittels Lichtsimulationen. Die Resultate ergeben Korrelationen zwischen der Empfindung von Helligkeit, Kontrast, Farbtemperatur und Farbigkeit und den Faktoren zu den beiden Modellen zum Erscheinungsbild. In Einzelfällen bestehen Modelle zur Voraussage des Erscheinungsbildes auf Basis der subjektiven Bewertung von Licht. Die Arbeit weist signifikante Unterschiede für beide Modelle zum Erscheinungsbild durch Veränderung der lichtphysikalischen Größen von Lichtstärkeverteilung und Lichtspektrum nach. Aus der ökonomischen Analyse der Experimente ergaben sich keine signifikanten Korrelationen zwischen höheren Investitions- oder Betriebskosten und einem entsprechend höheren subjektiven Preiseindruck der verschiedenen Beleuchtungssituationen. Fallstudien zu Gestaltungsrichtlinien zur Beleuchtung belegen die unterschiedlichen lichtplanerischen und lichttechnischen Strategien sowie deren Prozesse in der unternehmerischen Praxis. Die semiotische Analyse von Fallstudien betrachtet die Architekturbeleuchtung als Zeichen, die Merkmale des Erscheinungsbildes als Objekt sowie den Konsumenten als Interpretant und diskutiert Stärken und Schwächen in der Kommunikation. Auf diese Weise stellt die Arbeit eine differenzierte Verbindung zwischen Architektur, Beleuchtung und Marketing her

Predation efficiency of Anopheles gambiae larvae by aquatic predators in western Kenya highlands

Abstract Background The current status of insecticide resistance in mosquitoes and the effects of insecticides on non-target insect species have raised the need for alternative control methods for malaria vectors. Predation has been suggested as one of the important regulation mechanisms for malaria vectors in long-lasting aquatic habitats, but the predation efficiency of the potential predators is largely unknown in the highlands of western Kenya. In the current study, we examined the predation efficiency of five predators on Anopheles gambiae s.s larvae in 24 hour and semi- field evaluations. Methods Predators were collected from natural habitats and starved for 12 hours prior to starting experiments. Preliminary experiments were conducted to ascertain the larval stage most predated by each predator species. When each larval instar was subjected to predation, third instar larvae were predated at the highest rate. Third instar larvae of An. gambiae were introduced into artificial habitats with and without refugia at various larval densities. The numbers of surviving larvae were counted after 24 hours in 24. In semi-field experiments, the larvae were counted daily until they were all either consumed or had developed to the pupal stage. Polymerase chain reaction was used to confirm the presence of An. gambiae DNA in predator guts. Results Experiments found that habitat type (P < 0.0001) and predator species (P < 0.0001) had a significant impact on the predation rate in the 24 hour evaluations. In semi-field experiments, predator species (P < 0.0001) and habitat type (P < 0.0001) were significant factors in both the daily survival and the overall developmental time of larvae. Pupation rates took significantly longer in habitats with refugia. An. gambiae DNA was found in at least three out of ten midguts for all predator species. Gambusia affins was the most efficient, being three times more efficient than tadpoles. Conclusion These experiments provide insight into the efficiency of specific natural predators against mosquito larvae. These naturally occurring predators may be useful in biocontrol strategies for aquatic stage An. gambiae mosquitoes. Further investigations should be done in complex natural habitats for these predators

Programmed cell death and its role in inflammation

Cell death plays an important role in the regulation of inflammation and may be the result of inflammation. The maintenance of tissue homeostasis necessitates both the recognition and removal of invading microbial pathogens as well as the clearance of dying cells. In the past few decades, emerging knowledge on cell death and inflammation has enriched our molecular understanding of the signaling pathways that mediate various programs of cell death and multiple types of inflammatory responses. This review provides an overview of the major types of cell death related to inflammation. Modification of cell death pathways is likely to be a logical therapeutic target for inflammatory diseases

Lunar life in human places

Smart-lighting design is a rapidly growing area of interactive and cross-disciplinary design that is defining new practices in the profession. SuperLux is an international celebration of the ingenuity and artistry of the latest lighting technology and the Smart Light movement. The books three sections focus on projects that use light to animate architecture and media screens; new forms of lighting in industrial zones and public areas, including wayfinding and streetlighting; and interactive installations in urban spaces. Each section is punctuated by essays by leading experts and designers in the field

Towards an integrated health research process: A cloud-based approach

Today, health research and health care generate a steadily increasing amount of data. Making these available for secondary use cases is essential for efficiency gains in health research, e.g. by reducing time-and costs-intensive acquisition of data. In this contribution, we introduce our SAHRA software platform enabling reproducible research, e.g. by combining multiple data sources, performing data de-identification, and content filtering. We define an innovative research process combining retrospective and prospective research for the first time. Thus, authorized users, e.g. clinical researchers, are able to gain access through our system relevant research data and to perform interactive analyses. As a result, existing sensitive health data is securely transformed into de-identified research data, which can be used to improve future health research
