Eine systematische Übersicht über Fragebögen aus Lärmwirkungsstudien

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.

ERA-NET - Development of test methods for non wood small-scale combustion plants

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.

Coordination of national environment and health research programmes - environment and health ERA-NET (ERA-ENVHEALTH)

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.

Regeneration of the Robinson Crusoe's island original Forest (Juan Fernandez Archipelago, Chile)

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.

Managing water scarcity: Intelligent tools and cooperative strategies

MAI-TAI deals with integrated water resources management. It is designed as a coordination action of leading research and innovation operators, aiming at developing a coherent set of innovative, relevant and cooperative policy options and management strategies. Regionally it works with partners from China and India, and the work will focus around two lead river basins: The Hai river basin in North-East China and the Yamuna river basin in North India, both in arid and/or semi arid regions. The proposal features the following core coordination activities: 1. Enabling a dialogue between researchers and practitioners promoting state of the art and indigenous technologies and practices: The consortium believes that modern systems alone are not capable of solving the water needs of the people in many developing countries, and there is a strong need of generating innovative options through cross fertilization between both worlds. This cross-fertilization will be enabled by methods and rich experiences of user innovations research. 2. Based on (1), innovative policy options and management strategies will be compiled. Then, a multi-stakeholder interaction in order to evaluate these options and strategies will be carried out, supported by intelligent knowledge management tools: In the presence of a variety of actors (institutions, organisations, individuals) each with specific forms of knowledge with respect to scale, topic, reasoning processes, and a large number of information expected to be generated through the multi-stakeholder interaction, the issue of learning and knowledge management is of paramount importance. A strong impact of the coordination action is ensured by a highly inter- and transdisciplinary team, encompassing internationally reputable scientific institutions as well as strong governmental partners and NGOs. The latter two will considerable facilitate a wide and in particular meaningful stakeholder dialogue throughout the project.

Epigenetische Effekte bei transgenen Pflanzen: Auswirkungen auf die Risikobewertung

Im ersten Teil des Gutachtens wird auf Basis von Literaturrecherchen die Begrifflichkeiten zu epigenetischen Veränderungen und unbeabsichtigten Effekten bei transgenen Pflanzen geklärt. Im zweiten Teil des Gutachtens wird dargestellt, welche Ergebnisse zu unbeabsichtigten Effekten bisher bei transgenen Pflanzen in wissenschaftlichen Fachzeitschriften veröffentlicht wurden, und ergänzt durch Informationen, die durch eine allgemeine Internetrecherche gewonnen wurden. Gegenstand der recherchierten Arbeiten war die Stabilität der inserierten DANN- Sequenzen, Umordnungen und Rekombinationen, sowie deren Auswirkungen auf Regel- und Stoffwechselkreisläufe und letztendlich auf Inhaltsstoffe, Morphologie und Fitness der transgenen Pflanzen. Besonderes Augenmerk wurde auf Ergebnisse gelegt, die unter dem Begriff der pleiotropen Effekte bei transgenen Pflanzen zusammengefasst werden. Die Auswertung wurde auf transgene Pflanzen zur Lebens- oder Futtermittelverwendung beschränkt. Transgene Pflanzen, die Pharmazeutika produzieren sollen, wurden bei den Recherchen nicht berücksichtigt. Auf der Grundlage der Literaturrecherche werden die Auswirkungen epigenetischer Effekte bei transgenen Pflanzen auf Natur und Umwelt sowie die menschliche Gesundheit dargestellt und Empfehlungen, wie epigenetische und pleiotrope Effekte künftig geprüft und bei der Risikobewertung berücksichtigt werden können, erarbeitet. Dabei wurde das Guidance Document der EFSA (2004) als Referenz verwendet. Die Empfehlungen der EFSA werden diskutiert und Ergänzungen vorgeschlagen. Die Ergebnisse und Empfehlungen des Gutachtens wurden mit fünf Experten diskutiert, damit sowohl konsensuale Elemente als auch divergierende Meinungen der wissenschaftlichen Gemeinschaft hinsichtlich der Bewertung epigenetischer Effekte in transgenen Pflanzen deutlich werden. Dazu wurde mit den Experten ein Leifragen gestütztes Interview durchgeführt.

FP6-POLICIES, Aalborg Commitments Tools and Resources (ACTOR)

The Aalborg Commitments were adopted by the delegates to the June 2004 Aalborg+10 Conference with the intention that these clearly targeted actions will support European local governments in their implementation of the Aalborg Charter agreed at the 1994 Aalborg Conference. The initial commitment by signatory local governments is to undertake a baseline review within 12 months and then to enter into a local target-setting process in consultation with citizens and stakeholders in order to develop within 24 months a local programme of action under the ten Commitment themes. The evolution of the Aalborg process has been taking place at the same time as the European Commission has been preparing the Urban Thematic Strategy (UTS). This is one of seven Thematic Strategies, which together comprise the European Community's 6th Environment Action Programme. The EU has agreed that the theme of sustainable development should underpin all EU actions and this, therefore, is the key organising principle for the UTS. The SSP Fourth Call for Proposals outlines the following the core objective for 3.5. Task 5 as the 'Development of a set of guidelines and tools for signatories to the Aalborg +10 Commitments agreed in June 2004'. ACTOR will therefore have as its principal aim the development of a web-based innovative Toolkit, and a Training Package to support and assist Aalborg Commitments signatories to make efficient and effective progress. This Toolkit will include a comprehensive package of materials that can be provided to new towns and cities once they have signed the Commitments. In association with the Toolkit, the project will involve the design of Training Package on the methodology and operationalisation of the Aalborg Commitments. The Project will actively involve Signatory local authorities and the European Sustainable Cities and Towns Campaign Networks in developing and testing the Toolkit and Training Package. Prime Contractor: University of Northumbria at Newcastle; Newcastle Upon Tyne; United Kingdom.

Schwerpunktprogramm (SPP) 1158: Antarctic Research with Comparable Investigations in Arctic Sea Ice Areas; Bereich Infrastruktur - Antarktisforschung mit vergleichenden Untersuchungen in arktischen Eisgebieten, Investigating and revealing the nature and origin of electromagnetic reflections in polar ice by combination of numerical forward modeling techniques, ice core measurements, and radar field surveys

The investigation of glaciers and ice sheets by means of ice penetrating radar has become one of the most commonly used geophysical techniques in glaciology. Many applications utilise internal reflection horizons, assuming that an individual reflector is isochronous. Although the different mechanisms causing reflections are in principle understood, open questions on their origin still remain. The project presented in this proposal has the goal to identify the constituting processes leading to internal electromagnetic reflections in cold ice at all depth levels, providing a comprehensive picture of reflection origin. Investigation of the nature of electromagnetic reflections will be performed by a combination of ice core records, airborne and surface-based ice penetrating radar surveys, and newly developed numerical forward modeling approaches. Determining the physical properties of an ice core by means of dielectric profiling forms the basis to simulate the propagation of an electromagnetic wave in cold ice with a finite-difference model. Direct comparison of modeled radargrams with measured radar data validates the model results, allowing sensitivity studies with altered ice core data and yielding insights into the significance of the different reflection processes. Physical interpretation of the modeling results will be achieved by analyses of the crystal fabric and pore volume of ice and answer the question which reflection horizons are isochrones.

FP6-POLICIES, HCFCWORKSHOPS: International Workshop on HCFC Alternatives and Intermediate Reduction Steps for Developing Countries

The production and consumption of ozone-depleting HCFCs used as refrigerants, blowing agents, solvents, aerosols, and fire suppressants are increasing rapidly in developing countries, as they are being gradually phased out in developed countries under the Montreal Protocol. Because developing countries are not required under the Protocol to freeze consumption until 2016, or reduce consumption until 2040, global HCFC consumption could remain excessively high for the next 35 years, undermining the phaseout efforts of developed countries and threatening the recovery of the ozone layer and human health. Currently, there are only limited discussions on the post-2016 phaseout of HCFCs in developing countries. To address this issue, ICF is pleased to submit a proposal to support DG RTD/DG ENV in organising an innovative international workshop to target the reduction of HCFC consumption in developing countries between now and 2015, and yield a draft agreement on intermediate reduction steps between 2016 and 2040. Specifically, the workshop will provide developing country stakeholders with the technical tools needed to phaseout HCFCs (e.g., information on viable alternatives, technology transfer, funding opportunities) and to build consensus among stakeholders on an intermediate phaseout schedule to be implemented under the Montreal Protocol. After conducting numerous ODS-related analyses for DG ENV and countless other clients, ICF is intimately familiar with the sources and uses of HCFCs, available alternatives, key policy and industry players, and operational procedures of the Montreal Protocol. ICF is also experienced in designing and executing conferences and workshops, and developing outreach materials and Web content management systems. Further, with offices worldwide, ICF can conduct research, planning, and logistical activities seamlessly across the globe. If ICF is selected as the successful bidder, we look forward to negotiating mutually-acceptable contract.
