For economic reasons dough freezing technique is nowadays commonly employed in bakery business. There are, however, several issues connected with this technology. To improve the quality of a ready product, baked from frozen dough, some attempts concerning manipulation of production process parameters as well as supplementation of dough formulas with additives have been made. The aim of this study was to analyze the effects of various additives, including ready to use bakery products, on the crumb structure and specific volume of baked savory Danish dough. The research results show that by using most of the selected additives, an improvement of the volume and crumb structure of the product baked from frozen dough can be achieved. The only exception is the supplementation of the dough with 2% of trehalose. The most similar properties to the control sample, baked without the use of freezing technique, were observed in 3 formulas. One was made with the use of a commercial product, the second using fungal α-amylase, whereas the third - a blend of fungal α-amylase, glucose oxidase, fungal amyloglucosidase and enzymatic complex of lipases and xylanases. Nevertheless, an impact of these additives on the flavor profile of the dough was noted. © 2017 Elsevier Ltd

An effect of factors determining water quality in the water supply network in Kraków is assessed. The data collected over a four-year research period included quality parameters of water taken from the water distribution system in the period between 1 January 2011 and 31 December 2014. In the analysis the supply zones of four municipal water treatment plants in Krakow were considered. The selection of 29 water sampling points within the supply area allowed comparing water quality with respect to operational and technological aspects. Factor analysis enabled 4 components explaining correlations between tap water quality variables to be distinguished. It follows from the research performed that the obtained factors applied to 77% of overall water variability. The highest share was assigned to factor 1 that explained 32% of the chemical composition of water under consideration and was correlated with calcium, conductance, nitrates (V), magnesium and to a moderate extent with Σ THM (with negative sign).

This project builds on research that shows the disproportionate impact of the economic crisis on young people across Europe, including excessively high rates of youth unemployment and threats to the social provision enjoyed by previous generations. This is compounded by the coming of age of the descendants of recent migrant communities - who now form significant proportions of the young population in major European cities. They are Europeans in language, social habit and cultural repertoire, yet continue to face longstanding barriers as a result of membership of communities already marginalised from mainstream labour markets and wider civic life. The project brings together stakeholders from civil society experienced in practical policy-making and implementation with well-established academic researchers to: i) Map the changing demographic landscape of inequalities as seen in major cities in the EU today and the specific challenges facing young people disadvantaged by ethnic origin, cultural background, neighbourhood, family and educational and economic situation; ii) Review approaches of different levels of government to engaging with disadvantaged youth and addressing inequality concerning young people, including state approaches and 3rd sector actions for promoting economic activity and entry into the labour market and ensuring effective distribution of services and community-led initiatives to enhance economic chances and participation in civic life; iii) Uncover innovative strategies for navigating, surviving and overcoming inequalities that have emerged, and are emerging, among young people (16-24) in deprived parts of large cities through ethnographical research with young people themselves; iv) Examine the extent to which these strategies might be regarded as socially innovative, explore through a series of pilot projects how such strategies might be transferable across Europe and use the findings for reshaping policies at EU, national and local levels.

The overriding aim of this project is to conduct a comparative EU wide analysis on youth unemployment that is sensitive to gender, ethnic and class differences and the historical legacies of multi-level institutions shaping relevant policies. This aim will be achieved through 10 objectives organized around 12 research, management, dissemination and scientific coordination work packages. There are three cross-cutting research WPs that examine Performance, Policy Learning and its limitations and include the production of an International Handbook on Strategic Transitions for Youth Labour in Europe; Six substantive research WPs focus on issues of: Labour Market Mismatch in terms of education and skills as well as geographical mobility; Family and Cultural barriers to employment and, the opportunities and consequences of Self-Employment and Flexicurity. The central concept informing this project is based on a policy learning approach to address youth unemployment. This involves an ongoing process of including a wide range of EU stakeholders to inform the research and disseminate the results in different institutional conditions. It provides a recent historical analysis accounting for factors prior to, and following on from, the on-going economic crisis. It informs policy makers about of what works and why. The consortium will achieve the expected impact of 1) advancing the knowledge base of employment strategies to overcome youth unemployment, defining measures, methods and evaluations, 2) creating a critical network of stakeholder organisation. Outputs will include: An International Handbook on Strategic Transitions for Youth Labour in Europe. Multimedia dissemination: working papers, policy briefings, newsletters, press coverage and video podcasts. A comparative analyses of where and under which circumstances innovative and effective policies for getting young people into work are evident, where these policies work and why; Policy recommendations, from both case studies and quantitative analysis, on the impacts of these employment strategies; Timely and professional dissemination to key stakeholders facilitated by the partner EurActiv. Three WPs focus on the management, dissemination and scientific coordination of the project to achieve these objectives and outputs.

The project Malopolska Researchers Night will be implemented in the years 2014 and 2015 respectively for the eighth and ninth time. The event has already permanently inscribed in the calendar of Malopolska scientific events, enjoying growing from year to year popular among participants and becoming one of the biggest Nights in Europe. In 2013, this event was attended by over 55 thousand people, while in the first year of the project (2007) the event was attended only by 3.5 thousand people. The event program specified in the application is even richer than before it will take over 1 thousand activities, mainly interactive workshops, presentations, demonstrations and experiments as well as shows with the participation of scientists. It is estimated that 60 thousand people will participate in the events in 2014 and 65 thousand people in 2015. Malopolska Researchers Night is to first of all show participants how interesting is the work of scientists and how fascinating they are people. Through fun, in accessible and understandable way for everybody, we want to show that all around us is the science, and that scientists in their laboratories are working every day to make our life better, easier and more modern. The main motto of the project for the years 2014 and 2015 will be to present the successes of Malopolska scientists working in international scientific-research teams. The event will be held in six cities of the Region: Krakow, Tarnow, Nowy Sacz and Niepolomice and - for the first time in 2014 - also in Skawina and Andrychow. In addition, it is planned the live broadcast from selected locations via event website. The program will be prepared by almost 900 researchers, more than 1 600 students, about 120 research groups from more than 30 partners. Thanks to the extensive promotional campaign the information about the event will reach to nearly 3.5 million people each year.

Recently the interest of researchers has shifted from the analysis of synchronous relationships of financial instruments to the analysis of more meaningful asynchronous relationships. Both types of analysis are concentrated mostly on Pearson's correlation coefficient and consequently intraday lead-lag relationships (where one of the variables in a pair is time-lagged) are also associated with them. Under the Efficient-Market Hypothesis such relationships are not possible as all information is embedded in the prices, but in real markets we find such dependencies. In this paper we analyse lead-lag relationships of financial instruments and extend known methodology by using mutual information instead of Pearson's correlation coefficient. Mutual information is not only a more general measure, sensitive to non-linear dependencies, but also can lead to a simpler procedure of statistical validation of links between financial instruments. We analyse lagged relationships using New York Stock Exchange 100 data not only on an intraday level, but also for daily stock returns, which have usually been ignored. © 2014 The Author(s).

Entropy | Year: 2014

We consider the concept of generalized Kolmogorov-Sinai entropy, where instead of the Shannon entropy function, we consider an arbitrary concave function defined on the unit interval, vanishing in the origin. Under mild assumptions on this function, we show that this isomorphism invariant is linearly dependent on the Kolmogorov-Sinai entropy. © 2014 by the author.

In the last few years there have been many efforts in econophysics studying how network theory can facilitate understanding of complex financial markets. These efforts consist mainly of the study of correlation-based hierarchical networks. This is somewhat surprising as the underlying assumptions of research looking at financial markets are that they are complex systems and thus behave in a nonlinear manner, which is confirmed by numerous studies, making the use of correlations which are inherently dealing with linear dependencies only baffling. In this paper we introduce a way to incorporate nonlinear dynamics and dependencies into hierarchical networks to study financial markets using mutual information and its dynamical extension: the mutual information rate. We show that this approach leads to different results than the correlation-based approach used in most studies, on the basis of 91 companies listed on the New York Stock Exchange 100 between 2003 and 2013, using minimal spanning trees and planar maximally filtered graphs. © 2014 American Physical Society.
