In Fragebogen-Untersuchungen zur Lärmwirkung wurden bisher sehr unterschiedliche Operationalisierungen von Wirkungsvariablen (wie z.B. Belästigung, Störung von Aktivitäten) und außer-akustischen Faktoren (sog. Moderatoren wie z.B. Lärmempfindlichkeit, misfeasance) verwendet. Deshalb hat sich die Arbeitsgruppe community response der International Commission on the Biological Effects of Noise (ICBEN, Team No. 6) als langfristiges Ziel die Entwicklung von Fragebogen-Guidelines und die Formulierung eines Muster-Fragebogens für die Lärmwirkungsforschung gesetzt. D.h. es soll ein Vorschlag erarbeitet werden, in welcher Form globale und spezifische Lärmwirkungen in Befragungen erhoben werden sollten. Um dieses Vorhaben zu unterstützen, hat der Arbeitskreis Ökologische Lärmforschung die Erstellung einer systematischen Übersicht über vorhandene Fragebögen aus Lärmwirkungsstudien auf internationaler Ebene in Angriff genommen. Diese Übersicht soll es u.a. ermöglichen, die Struktur von verschiedenen Fragebögen sowie die in ihnen verwendeten Operationalisierungen für Lärmwirkungs- und Moderatorvariablen (hinsichtlich Art der Frageformulierung sowie der Antwortformate) zu vergleichen. Für den/die einzelne/n Lärmforscher/in bietet diese Übersicht die Möglichkeit, sich auf sehr effiziente Art und Weise darüber zu informieren, wie bestimmte Konstrukte in bisherigen Untersuchungen operationalisiert worden sind bzw. welche Alternativen zu den bereits selbst angewandten Operationalisierungen bestehen. Nach einer systematischen Ermittlung von Namen und Adressen einschlägiger Lärmforscher/innen, wurden diese um die Zusendung von Fragebögen sowie ergänzender Materialien aus eigenen Lärmwirkungsstudien gebeten. Die zugesandten Fragebögen werden gegebenenfalls übersetzt und mit der Methode der qualitativen Inhaltsanalyse ausgewertet. Hierbei werden die Fragebögen im Hinblick auf formelle Aspekte (z.B. Jahr der Erhebung, Sprache, Art der Befragungsmethode) wie auch im Hinblick auf strukturelle Aspekte (z.B. Umfang des Fragebogens, abgefragte Variablengruppen, Antwortformate) ausgewertet. Hauptgegenstand der Auswertung ist aber insbesondere die Auswertung der Lärmwirkungsvariablen (z.B. die Abfrage der globalen Lärmbelästigung, Aktivitätenstörungen, Kommunikationsstörungen) sowie der Moderatorvariablen (z.B. Lärmempfindlichkeit, Lärmbewältigungsvermögen, misfeasance). Parallel dazu wurde eine Datenbank entwickelt, in der die Ergebnisse der Analysen dargestellt und verwaltet werden. Diese Datenbank wird ab November 2001 im Internet unter http://www.eco.psy.ruhr-uni-bochum.de/nqd für jede/n interessierte/n Forscher/in zugänglich und nutzbar sein. Langfristig ist darüber hinaus geplant, ein Archiv mit den Original-Fragebögen aufzubauen, in dem einzelne Fragebögen auf Wunsch eingesehen werden können.
SP0 is conceived for coordination of the ICON research, for internal and external scientific exchange as well as for investigating development pathways of land use on the Philippines. The SP0 team will supervise the project activities as a whole, including reporting and final synthesis. It will design the ICON homepage, establish and maintain a web-based database and present the project and its results in scientific forums and public media. It will organize collaboration and scientific exchange with international networks dealing with atmospheric processes, global carbon, nitrogen, water and energy cycles, and long-term ecological research. Specifically, SP0 is devoted to ensuring a sound integration of the ICON project within the scientific communities of Germany and SE Asia. Supported by the ICON local research coordinator based at and employed by IRRI, it will coordinate with the IRRI farm management to assist other ICON subprojects with field setup, routine data collection and technical backstopping.
In the South-Indian city of Chennai (formerly called Madras), disastrous tropical monsoon linked with excessive precipitation frequently lead to wide-flat floods in the coastal plains. Caused by rapid urbanisation, the population in urban and periurban areas is more and more affected by these events. Besides the marginalised population living in disfavoured areas, increasingly also the more wealthy population that settles in flood prone areas is affected. Interdisciplinary assessments are needed to explain the complex causes of floods. The project analysed environmental aspects of risk exposure as well as socioeconomic aspects of risk perceptions and response strategies. By combining natural-scientific with socio-scientific approaches, a holistic perspective of the complex reasons and impacts of flooding could be covered. The project consisted of the following steps: 1. Analysis of flood risk exposure: Physio-geographic, hydrological and meteorological realities in risk areas were assessed using remote sensing (RS) data and geographical information systems (GIS). 2. Analysis of risk perception and management: Affected marginalised poor segments of the population, affected middle class groups as well as local planning authorities were interviewed to analyse local perceptions of floods and dominant management strategies. 3. Development of a flood risk map: The results of the risk assessment were integrated in an interactive flood risk map. The map - using several different layers - functions as a flood risk management tool including often neglected socioeconomic and socio-cultural parameters which reflect local vulnerability. 4. Holding of two workshops: A policy workshop with different stakeholders involved in flood management and affected by floods was held in Chennai in August 2007. This workshop was to foster communication and dialogue between different stakeholders and to create awareness on the current situation and problems in the area. A roundtable with the partners from India and organisations dealing with flood management and flood relief measures took place in October 2007 in Freiburg in order to present and discuss the findings and to strengthen future co-operation, communication and networks.

This project is part of the large multidisciplinary CCES project RECORD (Assessment and Modeling of Coupled Ecological and Hydrological Dynamics in the Restored Corridor of the River Thur). It deals with the role of microbial transformations and plant uptake in the cycling of nitrogen in different functional processing zones of a restored section of river Thur. The results will help to gain a better understanding of the filter function of restored river corridors and of their potential to emit greenhouse gases. Main hypothesis: Nitrogen fluxes and transformations in floodplains strongly depend on the specific response of microorganisms and dominant plants in different functional processing zones to the hydrologic conditions that vary with season and flooding events. Objectives: At the example of a restored section of river Thur, we want to gain a better insight into the role of riparian systems as sink or source of nitrogen species and the potential risks for drinking water sources and atmosphere. Specific objectives: - quantify the rates of microbial nitrogen transformations within the model floodplain: comparison between different functional processing zones, temporal variations due to seasonal climatic and biological effects and flooding events, dependence on governing soil parameters (temperature, moisture, redox potential). - quantify the rates of nitrogen species uptake by model plants (Phalaris arundinacea, Salix alba): potential uptake depending on nutrient availability and nutrient balance; effects of plant age and and temporary flooding. - measure and model nitrogen species concentrations in the soil solution and nitrous oxide emissions: comparison between different functional processing zones, temporal variations due to seasonal climatic and biological effects and flooding events. Methods: - Sampling and monitoring plots with a diameter of 8m have been set-up in different functional processing zones: (i) pasture in a neighboring non-restored section, (ii) river-forest transect including weakly colonized gravel, gravel covered by fine over-bank material densely overgrown with reed grass (Phalaris arundinacea) and other herbaceous species, zone planted with willow (Salix alba) during the restoration, mixed deciduous forest dominated by ash, (iii) old riparian willow forest. - Microbial nitrogen transformation rates are determined from soil samples taken from within the plots at specific times. Mineralisation immobilisation turnover (MIT) is determined by isotopic dilution, potential denitrification by acetylen-inhibition incubation. - Specific nitrate and ammonium uptake rates by model plants are determined in hydroponic treatments in the climate chamber. - Soil respiration and trace gas efflux/influx is measured by in-situ gas sampling from within large rings permanently installed on the plots followed by GC analysis. Etc.
The ARCHAIA project aims at implementing two training seminars on cultural heritage based on an innovative integrated perspective deriving both from the human and the natural sciences. The seminars address 90 post-graduate students, scholars and professionals of different backgrounds. Starting from the need of disseminating the results of 9 funded EU research projects and COST actions, we aim at presenting these within an innovative framework, i.e. a global approach towards planning and management of archaeological parks starting from the very first steps of field research and going through the characterisation of the materials retrieved and topographical studies in order to mould every bit of historical information within a coherent project, properly displayed for the public. Through an innovative didactic methodology, innovative scientific contents will be disseminated. Dealing with the initial program of archaeological research in the field, integrated with techniques of archeobiological and geoarchaeological investigation, our final goal is to supply the participants with the guidelines for moulding research strategies and managing archaeological sites, in order to be able to publicly display the historical content derived from research results and effectively proceed to the protection of the cultural heritage. One training seminar will be in Copenhagen and another one in Bologna. Five key topics have been selected: Topic 1 concerns Topography, surveying and landscape archaeology, Topic 2 Archaeological research and restoration of monuments, Topic 3 Material culture characterization, Topic 4 Anthropology and environment and Topic 5 Data processing and public presentation. The dissemination of the lectures presented through a monograph and multimedia products will also supply guidelines for integrated protocols on the management of archaeological sites, set in their landscape, within a global perspective.
Background: Within the framework of MONITRAF, work package 5 deals with road traffic related effects on the alpine space from the sustainability point of view. Public health impacts will be evaluated among other topics. Established methods to quantify public health impact from road traffic exist for large scale assessments on a national base (e.g. trinational impact assessment study for Switzerland, Austria and France). Such assessments are done by transferring the results from large scale cohort studies on the exposure situation of the region of interest. Methodologically more demanding are small-scale impact assessments along the transit axis. The application of such established large scale assessments is methodologically questionable. However, an alternative method has not been recognized as a number of scientific questions have not been solved yet. Objectives: Main goal of the public health project is to coordinate ongoing studies on health effect from transit traffic: Department for Hygiene, Microbiology and Social Medicine, Innsbruck; Dr. Lercher: Brenner Basistunnel; Institute of Social and Preventive Medicine, Basel, Dr. Hazenkamp & Dr. Rapp: Gotthard Transitverkehr; Published health impact assessment studies of air pollution and noise will be analysed and applicability of the methods in the given context will be evaluated and the data prerequisite will be clarified. Available data which is needed for an impact assessment will be evaluated. Based on data availability and methodological considerations a method to assess public health impact from transit traffic will be proposed. Work steps: - To obtain an overview of ongoing research activities in Innsbruck and Basel (e.g. to organize a joint meeting). - To summarize published results from those ongoing studies and to give an overview of future results which can be expected. - Systematic literature search of traffic related health impact assessment studies and evaluation of their methodologies with respect to applicability within MONITRAF. - Evaluation of exposure concepts or indicator measurements which may serve as base for a health impact assessment study of air pollution (e.g. different kind of pollutant, long term mean levels, short term pollution levels, distance to the road, effect of air pollution intervention studies) - Evaluation of exposure concepts or indicator measurements which may serve as base for a health impact assessment study of noise (mean dB(A), variation, distance to the road, etc.) - Coordination of the module 'noise and air quality' of work package 5 with respect to the assessment of possible useful indicator measurements from a health effect perspective as well as the availability of such data. - To clarify the data availability for suitable health impact assessment study methods. - To propose a suitable method for a health impact study of alpine road traffic and design the study.
Ziel des Projektes war die Erarbeitung eines Qualitätshandbuchs mit einheitlichen Standards zur Qualitätssicherung bei Dichtheitsprüfungen privater Abwasserleitungen. Als Grundlage wurden ausführliche Interviews mit 38 Städten und Gemeinden in NRW und 2 Städten in Hessen geführt und 214 Dichtheitsnachweise in verschiedenen Kommunen Nordrhein-Westfalens hinsichtlich ihrer Qualität ausgewertet. In den Interviews zeigten sich Unterschiede und Unsicherheiten bezüglich der möglichen Vorgaben zur Prüfmethode, zur Dokumentation und zur Vorlagepflicht sowie eine unterschiedliche Interpretation des Umgang mit Regenwasserleitungen im Mischsystem. Unsicherheiten bestehen auch bei der Kalkulation des Personalbedarfs und bei der Festlegung des Umfangs einer Prüfung von eingereichten Dichtheitsnachweisen. Bei der durchgeführten Qualitätsprüfung der Dichtheitsnachweise anhand eines erarbeiteten Bewertungskataloges stellte sich die Qualität der Prüfungen insgesamt als ausreichend bis zufrieden stellend dar, wobei die optischen Inspektionen etwas besser abschnitten. Verbesserungspotential besteht bei der Schadensansprache und bei der Art und Tiefe der Dokumentation der Prüfungen. Dies betrifft vor allem die Dokumentation untersuchter und auch nicht untersuchter Leitungsstränge und die digitale Aufzeichnung des Messverlaufs bei Prüfungen mit Wasser oder Luft. Unter Berücksichtigung der Ergebnisse der geprüften Dichtheitsnachweise werden technische Anforderungen an die Durchführung der Dichtheitsprüfung und an den Umfang und den Inhalt der im Rahmen der Dichtheitsprüfung zu erstellenden Unterlagen definiert. Darüber hinaus werden Kriterien für die Wahl der Prüfmethode anhand der Schutzziele Umwelt- und Gesundheitsschutz, Schutz der öffentlichen Abwasseranlage und Eigentumsschutz aufgezeigt. Eine Verbesserung der Qualität lässt sich vor allem durch eine systematische Kontrolle der Unterlagen durch die Kommunen erreichen. Für die verschiedenen Prüfumfänge wird der Bearbeitungsaufwand abgeschätzt, wobei über eine Kombination einer einfachen Plausibilitätsprüfung mit einer detaillierten inhaltlichen Prüfung, die stichprobenartig, aber systematisch durchgeführt wird, der Aufwand erheblich reduziert werden kann. Die Ergebnisse der Überprüfung sollten mit den Sachkundigen diskutiert und für eine weitere Nutzung standardisiert dokumentiert werden. Auf dieser Basis können auch Schulungsschwerpunkte ermittelt und Nichtempfehlungen oder Ausschlüsse ausgesprochen werden. Eine weitere Option sind Zusammenschlüsse.
Honey is among the oldest food products of mankind and beekeeping is deeply rooted in every European culture. Numerous European and national regulations control honey quality, which reflects both the high nutritional and societal value of the product. Yet in an environment with increasing chemical pollution and the wide use of agrochemicals, honey runs high risks of becoming chemically polluted. In addition a broad spectrum of chemicals is used to treat honeybee diseases, further contaminating honey with sometimes highly toxic compounds. The BEE SHOP is a network of ten leading European honeybee research groups in honey quality, pathology, genetics and behaviour as well as selected beekeeping industries, which all share a common interest in promoting Europe's high honey quality standards. The prime goal is to reduce potential sources of honey contamination due to both foraging contaminated nectar and chemotherapy of honeybee diseases. The BEE SHOP will therefore deal with the development of biological resistance to pests and pathogens to avoid chemotherapy. Various European honeybee races and populations will be screened for their disease resistance potential to the main pressing pathogens. Differences in foraging patterns among European honeybees and their underlying mechanisms will be studied to identify behavioural traits reducing contamination. Differences in disease susceptibility will be genetically analysed by QTL mapping. Major loci in the genome will be identified with the aid of the published honeybee genome. SNPs will be developed to allow for selection of specific target genes in both drones and queens before insemination. This will greatly accelerate the selection progress in honeybee breeding allowing for the swift establishment of resistant but efficient stock. New tools for testing honey quality and authenticity will be developed to allow inspections of honey according to the current EC directives on honey quality and organic beekeeping.
