Most of the insulation materials used in construction has a huge impact on the environment throughout their life cycle. Therefore making a product of improved operational and environmental performance indicators is a real challenge for the designers. The widespread usage of composite materials gives more opportunities to achieve this goal. This article describes a conceptual model of an insulating material obtained on the basis of rubber crumbs and expanded perlite of improved environmental and functional performance indicators. The MET matrix is used to determine significant and problematic areas in terms of the environment. The results show that the material under investigation meets the eco materials established literature operational and environmental requirements.

The proposed project will develop a method for scaling down the analysis of policy impacts on multifunctional land uses and on the economic activities. This method will rely on micro-simulation and multi-agents models, designed and validated at municipality level using input from stakeholders. The models will address the structural evolution of the populations (appearance, disappearance and change of agents) depending on the local conditions for applying the structural policies on a set of municipality case studies. We shall consider policies related to use of Structural Funds (SFs), Cohesion Fund (CF), Preaccession funds (PAFs) and EAFRD (respectively CAP). This project will include the following actions: - Review the EU structural policies, identify driving forces at EU, national and regional levels for multifunctional land use activities and provide baselines for the design of national and regional scenarios on multifunctional land use activities. - Interaction with stakeholders: pre-model engagement with stakeholders in terms of scenario design and formulating agent decision rules for agent-based models, on-model engagement with stakeholders mirroring agent-based models, and post-model engagement with stakeholders in terms of assessing model outputs. - Design and develop micro-simulation and multi-agents models, of local dynamics and of the impact of European structural policies at the municipality level. - Build a mapping between available data on municipalities and prototypical, contrasted evolutions of micro-simulation and agent based models. This will allow us to aggregate the results provided by these models at a regional level, on a set of regional case studies, and to compare these results with existing models at regional scale. - Investigate the potential of the approach to design a method that enhances the scope of Strategic Environmental Assessment (SEA), Environmental Impact Assessment (EIA) and Sustainable Impact Assessment (SIA).

Pesticides are defined as chemical substances protecting plants from pathogens, insects, nematodes and weeds. They are used to secure yields, improve quality of food and facilitate harvesting. However, their heavy use in agriculture resulted in pest resistance, ground, surface and water contamination as well as possible health problems on farmers/operators and consumers. Within this context, the objective of the proposed research stems from the need to provide a solid methodological framework and empirical evaluation which will assist policymakers in identifying the true impact of pesticides on agricultural production. The obtained results may well serve as a benchmark for the foundation of future EU policy schemes aiming at achieving a sustainable use of pesticides in European agriculture. In this respect, the proposed project intends to provide an accurate assessment of the external costs of agricultural pesticide use and contribute to the relevant EU policies by developing tools for designing a socially optimal tax and levy scheme aimed at the reduction of pesticide use to its socially optimal level. Specific consideration will be given to the effects of the accrued scheme and alternative policy tools on the socially optimal pesticide use, as well as on economic sustainability and social welfare. Moreover, the proposed research will identify means that can help in the promotion of more integrated pesticide management practices. The project fulfils its aims by combining traditional and well-established theoretical methodologies with the most recent advancements in economic theory, biological and technical scientific work, ultimately developing a consistent and integrated analytical framework. The validity of the employed theoretical models and policy tools will be extensively verified by applying them in selected EU countries, thereby accounting for the diversity in pesticide use among producers in different geographical locations.

The overall aim of this project is to offer a deeper understanding of the different mechanisms involved in the management of chronic conditions with a specific focus on how initiatives are translated and embedded into the illness management practices in peoples everyday life. It is in work, domestic and community settings where these practices are shaped by the emotional, symbolic, ethical, economic, and institutional inter-dependencies that people have with intimate and distant others, and where personal health is constantly negotiated in relation to ones own well-being and the health and well-being of others. Framed this way, questions related to self-care practices and changes in health behaviours can be stated as a shift in emphasis to a broader agenda for the provision of healthcare. Such an agenda brings into view ideas dominant in academic and policy debates and discussions of self-management which has drawn attention to the limitations of deploying a one size fits all approach and the need to devise and implement workable, personally sensitive strategies for self-management and behaviour change that make full use of available technologies (e.g. eHealth, telehealth, virtual networks), personal, community and institutional resources, and which more adequately addresses the needs of socially disadvantaged people. Thus, the current focus on individuals (e.g. understanding and improving their knowledge and capabilities) requires a complementary focus on understanding capabilities, resources, and change in health related practices as an integral part of peoples social networks and as being co-shaped by wider determinants of health). There is also a need to focus on the translation of efforts within health services to explore how professionally defined priorities of chronic illness management are translated acted upon and resourced outside of the consultation.

The design of effective and targeted CAP measures relies on a proper assessment of the impacts of EU policy changes and market developments on farmers and the whole economy. Uncertainty, instability and price volatility that relentlessly reshape agricultural markets today, call upon the development of new modelling tools able to scrutinise all relevant dynamics while also remaining easy to use and amend. The project improves and extends existing economic models that make use of the FADN informatics environment by developing a unique modelling framework that (i) encompasses all aspects of farmers production decisions (ii) targets the single farm but also consistently aggregates to regional, national and the EU level (iii) takes into consideration the effects of uncertainty and risk on farmers behaviour (iv) can be employed in different market environments, i.e. throughout the EU-27 and (v) can be amended and/or fine-tuned by EU and national FADN units. The project draws upon two major modelling tools (econometric and mathematical programming), while the validity of the employed theoretical models will be verified by their empirical application in each EU-27 country. The projects final outcome is the construction of a methodological framework comprised of state-of-the-art economic models custom-built for the FADN database that will provide to policy makers an inclusive impact analysis of the effects of alternative policy and market developments scenarios under a real-life, dynamic context. Given the complexity of this framework, a simplified version of the models will be developed, all consistently and operatively joined into an amendable interface that will be user-friendly and easy to operate and still allow for a concise replication of our policy simulation results, capable to target at the efficiency of CAP measures, i.e. the single farm payment, although the whole framework will be also applicable providing some acquaintance with modelling parameterisation.

In FarmPath, we propose that increasing sustainability in agriculture is best addressed by enabling flexible combinations of farming models, which vary to reflect the specific opportunity sets embedded in regional culture, agricultural capability, diversification potential, ecology, and historic ownership and governance structures. We will enable progress towards this goal of increased regional sustainability of agriculture through a transdisciplinary research approach, where knowledge is co-produced by scientists, stakeholders and practitioners. FarmPath will specifically integrate theoretical and conceptual approaches to transition and transition management with recent research on adaptive capacity and resilience in farming systems, food regimes, and farm level transitions to multifunctionality, and build on previous EC funded research projects on sustainability and innovation in farming systems, and production and consumption chains. FarmPath will assess a set of farm and regional level sustainability initiatives to identify conflict and complementarity, focusing on how combinations of initiatives, actors, technologies and policies can achieve synergies which initiate transition pathways at regional level. FarmPath will engage in participatory visioning and scenario assessment in contrasting national and European regions, to identify transition pathways: combinations of visions and the social and technical mechanisms and innovations needed to reach these visions. This will lead to the development of a handbook for assessing and identifying actions which can be taken by policy makers to facilitate transition towards regionally sustainable agriculture. FarmPath will also investigate issues surrounding young people and new entrants to farming in specific relation to these initiatives and scenarios. Research findings will be presented and discussed in an international conference, and developed into an academic book.

The literature published in the last 3 years trying to explain agricultural markets instability during 2007-2009 offers inconclusive results about its causes and impacts. On balance, available scientific evidence gives insufficient guidance for prioritizing policy initiatives, and for effectively averting and mitigating new food crises. Based on an integrated approach, Project ULYSSES seeks to provide general, but sufficiently detailed, responses to the main questions that have been recently posed in the literature and debated in political sphere: a)What are the causes of markets volatility increases since 2007?;b)What drivers are volatility-increasing and which others are price level-increasing?; c)How likely is that the main commodity markets will experience new episodes of large volatility?d)To what extent increasing volatility affects agents in the value chain?;e)What are the actual impacts on the most vulnerable households in the EU and in selected developing countries?; f)What policies are more effective to avert and mitigate the effects of markets volatility at the EU and international levels? ULYSSES has six objectives: 1.Review the literature on prices volatility of food, feed and non-food commodities 2.Analyse agricultural markets, using updated data, new methods and markets linkages with a view to determine the causes of markets volatility 3.Identify and evaluate the drivers and factors causing markets volatility, and make projections for supply shocks, demand changes and climate change impacts on agricultural production. 4.Evaluate the impact of markets volatility in the food supply chain in the EU and in developing countries, analysing traditional and new instruments to manage price risks. 5.Evaluate impacts of markets volatility on households in the EU and developing countries. 6.Draw policy-relevant conclusions that help the EU define market management strategies within the CAP after 2013 and inform EUs standing in the international context.

At present, transition towards electromobility in urban transport and related companies are among the most studied industrial areas. Different EU countries implement different methodological and business approaches to investigate the possibilities for the acceleration of electromobility integration in urban transport. Studies on these approaches to be shared within the project consortium and with different stakeholders (local authorities, producers of electric vehicles and recharging stations) will provide the basis of the initiative for increasing the interest in electromobility integration in urban transport as a multi-dimensional innovation. The thin red line of electromobility practical integration passes through the sharing of innovative ideas with relevant stakeholders by carrying out field studies, in-depth interviews and electronic on-line studies. EMobilita overall objective is to study the conditions, prerequisites and incentives for electromobility integration in urban transport and elaboration of a roadmap for its development. The specific objectives are: To explore the experience of the European countries in the integration of electromobility in urban transport and to identify good practices; To summarize direct and indirect multi-dimensional effects (social, economic and environmental) of the introduction of electromobility in urban transport schemes; To elaborate a roadmap with concrete measures for introducing electromobility in urban transport; To establish a sustainable partnership between universities and businesses through staff exchange and networking activities. In order to achieve our objectives we created a network of academic and non-academic institutions from Bulgaria, Slovakia, Italy and Greece.

We are concerned with an MIGI1IK queue in which service time distribution of the first customer in each busy period differs from the distribution of service times of the other customers in the same busy period. The service time of each customer in every busy period depends on queue - length immediately after the service-start epoch if the current service is not the first in the busy period. This model is called an exceptional service model. Our major interest is to apply sample-path analysis and to get transform-free stationary queue-length distribution and remaining service time. ©2010 IEEE.

Local Production Systems (LPS) could be characterized in different ways, thus their definition is neither simple, nor unified task. One of the most popular definitions is the one given by Local Production & Innovation Systems Research Network territorial union of economic, political and social actors, whose efforts are focused on a specific group of interrelated activities. LPS have strong impact on regional development. To this end, LPS establishment and functioning in the EU member states and in third countries are subject to intensive research and discussed in different strategic documents. As of the 90s of the last century LPS in EU(15) are in a process of constant development while in the new EU MS and in third countries they are still in the initial phase. The world economic and financial crisis further attracted the attention of the researchers to LPS establishment and functioning. FOLPSEC aims at deepening the theoretical studies on LPS and to encourage their practical implementation as an approach for world crisis overcoming. It has the following objectives: 1. To exchange knowledge on research approaches in studying LPS and to make recommendations for EU good practices implementation in the conditions of economic crisis; 2. To share partners results on LPS functioning concerning economical and social regional acceleration and regional disparities relative overcoming; 3. To make use of knowledge gained and good practices identified for research and teaching purposes at all partner institutions; 4. To establish long-term research cooperation between EU and Third countries and to strengthen research partnerships. In order to achieve our goal we created a network of partner institutions located in EU(27) member states (Bulgaria, Poland and Slovakia) and in Eligible Third Countries (Russia and Ukraine).
