Das Projekt "Eine systematische Übersicht über Fragebögen aus Lärmwirkungsstudien" wird/wurde gefördert durch: Ministerium für Schule und Weiterbildung, Wissenschaft und Forschung Nordrhein-Westfalen. Es wird/wurde ausgeführt durch: Universität Bochum, Arbeitsgruppe für Umwelt- und Kognitionspsychologie.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.
Das Projekt "ERA-NET - Development of test methods for non wood small-scale combustion plants" wird/wurde gefördert durch: Kommission der Europäischen Gemeinschaften Brüssel. Es wird/wurde ausgeführt durch: Höhere Landwirtschaftliche Bundeslehranstalt Francisco-Josephinum.Non wood fuels for small-scale furnaces have attracted increasing interest in several European countries. New technological approaches are on the way, but the verification of any such developments is difficult and there is a large uncertainty about testing procedures and equipment. While for wood combustion standardized European measuring regulations are available and broadly applied, the testing of cereal fuel combustion is generally not following a commonly accepted procedure. Consequently the results of such measurements are not fully comparable. This applies particularly for the international level, which is here of particular relevance due to the fact that a combustion technology development for a niche application can only be economically viable if a sufficiently large marketing area can be taken into focus. The overall objective of the proposal is therefore to contribute through research to the development of uniform and comparable European procedures for testing of small-scale boilers up to a power out of 300 kW for solid biomass from agriculture like straw pellets and energy grain. The driving forces and barriers will be worked out; existing legal regulation for the installation (approval by the local authorities) in the participating countries will be collected. The state of the art of the non wood biomass boiler technology will be identified; the need for standardized tests for type approval tests and the measures to establish a European Standard will be shown. Measurement methods with special emphasis on efficiency and emissions will be worked out and the requirements and specifications of test fuels will be proposed. Test runs will be carried out following preliminary test procedures based on existing European standards for wood boilers. Based on the results of these test runs a draft for a Europe-wide uniform test procedure will be proposed. Preparatory work for a European standardization process including a round robin test will be done.
Das Projekt "Schwerpunktprogramm (SPP) 1176: Climate and Weather of the Sun-Earth-System (CAWSES); Klima und Wetter des Systems Sonne/Erde, SOLEIL: Solar variability and trend effects in layers and trace gasesin the upper atmosphere" wird/wurde gefördert durch: Deutsche Forschungsgemeinschaft. Es wird/wurde ausgeführt durch: Leibniz-Institut für Atmosphärenphysik e.V. an der Universität Rostock.Various layers exist in the summer mesosphere at middle and polar latitudes which owe their existence to water ice particles. These layers are called ‚noctilucent clouds' (NLC), ‚polar meso- sphere clouds' (PMC), and ‚polar mesosphere summer echoes' (PMSE) which reflects different observation geometry or entirely different physical processes involved. These layers are very sen- sitive to temperature (and to a lesser extent to H2O) and are therefore best suited to indicate long term and solar cycle changes. Indeed, variations on decadal time scales of different layer parameters (occurrence frequency, layer brightness etc.) have been reported from ground and satellite based observations. However, the physical and photo-chemical processes involved are not understood and some of the observations contradict expectations. In this proposal we want to study the long term (decadal scale) formation of layers in the polar summer mesopause region, in particular their sensitivity to variations of background conditions caused by solar forcing and anthropogenic increase of greenhouse gases. We investigate and complement the available observations on layers (NLC/PMC/PMSE) and trace gases (ground based microwave and satellite observations of H2O) and perform model calculations with the LIMA GCM model. In the third phase of the SPP we want to study in particular the feed back mechanisms of ice formation on the atmosphere (e. g., through freeze drying) and the coupling mechanisms to above and below.
Das Projekt "Health effects of indoor pollutants: integrating microbial, toxicological and epidemiological approaches (HITEA)" wird/wurde gefördert durch: Kommission der Europäischen Gemeinschaften Brüssel. Es wird/wurde ausgeführt durch: Terveyden ka Hyvinvoinnin Laitos.Objective: Healthy housing and good indoor air quality are important goals of public health. However, biological indoor pollution due to dampness, moisture and mold is an emerging environmental health issue, as recognized in EU indoor air policy documents. Prevalence of dampness is remarkable, and may still increase due to demands of energy savings and extreme weather periods and floods associated with climate change. The exposure may lead to long-term impacts such as asthma. The documentation is strong on association between building mold and health, but the causative agents and disease mechanisms are largely unknown, which impedes recognition of a mold-affected patient in health care. Efficient control and regulation are hampered by the insufficient understanding of these causalities. Understanding of the links between building practices and health is lacking. There is an urgent need for European-wide knowledge to form a basis for establishing building-associated criteria for healthy indoor environments. The aim of this proposal is to clarify the health impacts of indoor exposures on children and adults by providing comprehensive exposure data on biological and chemical factors in European indoor environments.
Das Projekt "Coordination of national environment and health research programmes - environment and health ERA-NET (ERA-ENVHEALTH)" wird/wurde gefördert durch: Kommission der Europäischen Gemeinschaften Brüssel. Es wird/wurde ausgeführt durch: Agence Francaise de Securite Sanitaire de L'environnement et du Travail.Objective: It is estimated that around 20Prozent of the burden of disease in industrialized countries can be attributed to environmental factors, and the magnitude of the problem is perceived by the majority of Europeans. The assessment of health impacts is based mostly on scarce exposure data and limited information on the relationship between exposure and health. There is, therefore, a need to strengthen research in this area and to develop methods and tools which will improve the comparability of data. Member States have developed skills and expertise using different mechanisms to fund environment and health research. The scientific boundaries created by the remits of different funding organisations have frequently acted as a disincentive to collaborative working. Although aims are towards relevance and efficiency, the results remain dispersed and not of actual support for policy-making. Therefore, results of the studies in ERA-ENVHEALTH will lead to the proposal of a coherent set of proposed priorities, implementation of joint activities, and common calls. ERA-ENVHEALTH, by bringing together 16 participants from 10 countries, will contribute to establish collaboration among the different funding organisations of environmental and public health research communities.
Das Projekt "Schwerpunktprogramm (SPP) 1158: Antarctic Research with Comparable Investigations in Arctic Sea Ice Areas; Bereich Infrastruktur - Antarktisforschung mit vergleichenden Untersuchungen in arktischen Eisgebieten, Comparison of Arctic and Antarctic microbial communities: abundance, phylogeny and ecology" wird/wurde gefördert durch: Deutsche Forschungsgemeinschaft. Es wird/wurde ausgeführt durch: Stiftung Alfred-Wegener-Institut für Polar- und Meeresforschung e.V. in der Helmholtz-Gemeinschaft (AWI).In the scope of the planned project the diversity and ecology of microbial communities and their functions in nutrient turnover under the extreme conditions in Arctic and Antarctic periglacial environments will be studied. Polar regions are vast and unique natural laboratories, both because of their geographical isolation and the minor anthropogenic influences active there, for studying microbial life under extreme environmental conditions. For this purpose the diversity and abundance of the microflora in dependence of important site characteristics such as hydrological, thermal and weathering processes will be investigated in different habitats on Store Koldewey (East Greenland) and Livingstone Island (Antarctic). The main objectives are the genotypic and phenotypic characterization of the microbial community by cultivation-independent methods such as lipid profiling and rRNA-based analyses. Stable isotope probing will be used to identify the main microbial players in nutrient turnover in the different environments. The acquired data will give insights into the early stage of life on Earth, the development of extreme habitats and the functioning of microbes within the ecosystem. The planed study contributes to the research topics of the International Polar Year proposal entitled Antarctic and sub-Antarctic Permafrost, Periglacial and Soil Environments (ANPAS, No. 627) leaded by Dr. Jan Boelhouwers.
Das Projekt "Schwerpunktprogramm (SPP) 1167: Quantitative Niederschlagsvorhersage, High-resolution Reanalyses and Impact Studies for Improving Process Understanding and Precipitation Forecast Skill based on the COPS Data Set" wird/wurde gefördert durch: Deutsche Forschungsgemeinschaft. Es wird/wurde ausgeführt durch: Deutscher Wetterdienst.Quantitative Precipitation Forecast (QPF) is one of the major challenges in numerical weather prediction (NWP). This is true for QPF ranging from synoptic-scale to small-scale convection. The main goal of this proposal is to improve the short-range QPF on scales of a few hundred km and a few hours. To achieve a significant improvement of QPF on these scales the atmospheric variables, which are representing the pre-convective conditions, need to be determined. Hence an innovative combination of data assimilation techniques and observations is proposed. Within this project, 4D water vapour, as well as wind and cloud data are considered. The focus is on advanced observing systems with high future potential such as GPS, lidar, passive remote sensing from geostationary satellites as well as novel in-situ sensors. Different state-of-the-art assimilation techniques will be compared to find the optimal approach to improve QPF. After the development of suitable observation operators, the optimal use of advanced remote sensing systems will be investigated using various Observing System Experiments (OSE's) and Observing System Simulation Experiments (OSSE's). To quantify the success, model independent data sets inferred from MSG/radar, GPS, and an innovative sounding system will be used for validation.
Das Projekt "Regeneration of the Robinson Crusoe's island original Forest (Juan Fernandez Archipelago, Chile)" wird/wurde gefördert durch: Ministerio de Planification y Cooperacion Chile. Es wird/wurde ausgeführt durch: Universität Freiburg, Waldbau-Institut.The Juan Fernandez Archipelago National Park, and World Biosphere Reserve, is composed of three oceanic islands located 680 km west of continental Chile at 33 degree S. Its biota and in particular the flora is characterised by its diversity and high degree of endemism (63,9 percent), resulting from a long process of local evolution without anthropic influence. The Robinson Crusoe Island (RCI) is the only permanently inhabited of the archipelago, presenting human influence since 1574 (629 inhabitants). From this moment on, fires, selective cuttings and the introduction of exotic species of flora and fauna have affected enormously the forest communities. Currently 75 percent of the endemic vascular flora is considered in verge of extinction, being urgent its conservation. The original forest communities of the RCI constitute an important part of the endangered species habitat. Unfortunately there is still unclear the natural ecology of the dominant tree species. This evidence is crucial to consider in any conservation and restoration proposal. The objective of this study is to analyse where occurs the regeneration of the main tree species of the RCI original forest (Myrceugenia fernandeziana (Hook. & Arn.) Johow, Fagara mayu (Bertero ex Colla) Engl., and Drimys confertifolia Phil.). Using a forest area as case study (Plazoleta el Yunque sector) it will be assesed i) if the regeneration follows a light gradient, ii) if the species demand certain characteristics on its regeneration habitat (e.g substrate, rocks, coverage) and iii) how the main weeds (Aristotelia chilensis (Molina) Stuntz, Rubus ulmifolius Schott) affect the natural regeneration in gaps. As expected outcomes is considered the understanding of regeneration niche characters for the main tree species, and the identification of key site aspects (indicators) for the original forest self replacement. This knowledge might contribute basic information, to propose further conservation and restoration activities for this ecosystem.
