Globalization and ICT rapid development have led to strong competition between educational institutions. Advanced analytical technologies, including Business Intelligence (BI) tools, are implemented at universities worldwide for analyzing data and getting profound knowledge of the students, their individual learning characteristics and specific educational needs. This paper presents an example of BI implementation for student data analysis. Source

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. Source

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.

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.

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).
