Abstract

This special issue of Perspectives on Federalism collects papers mostly presented at the General Conference of the European Consortium of Political Research in September 2014. The issue contains five papers dealing with the role, the status, the dynamics, and the functions of sub-national constitutional politics and sub-national constitutionalism in a number of member states of the EU as well as in a comparative, non-EU perspective. Even though the papers take different perspectives on the topic at hand, they all engage with the contribution sub-national constitutions can make to democracy and the nationstate within as well as outside of Europe.

Abstract

The ability to use computer simulation to predict the behavior of oil spills at sea enables better use of available personnel and resources to combat such spills. The use of oil collecting equipment properly selected to suit the conditions is essential for the operation to be effective. Therefore, an attempt is made to verify the influence of weather conditions on the efficiency of oil recovery. Three types of spilled crude oil were simulated. A relevant experiment was conducted on a PISCES II oil spill simulator.

Abstract

The premises of international airports in CR are major air transport hubs as well as key elements of critical infrastructure, belonging to the very high risk category. Any infringement leading to limitation or complete shutdown would cause considerable economic and psychological damage. The most important task is to ensure high quality and reliable physical and technical protection of the airport, because especially in the summer months these areas collect large numbers of people and a possible terrorist attack could be fatal. This paper focuses on assessing the possibilities of solving the problem of IEDs hidden in travel luggage, and their initiation by X-rays during security checks.

Abstract

The aim of the present paper is to reflect upon the place of pronunciation in English as a foreign language (EFL) teaching at different educational levels in Poland. To collect the data, an on-line survey was conducted among EFL professionals teaching at primary, lower secondary, and higher secondary schools in Poland. The questions focused on the respondents’ beliefs about pronunciation, teachers’ competences regarding pronunciation and pronunciation teaching, and the pronunciation teaching techniques they use. The results depict the most and least frequently used pronunciation teaching techniques at each of the three educational stages, and the beliefs of EFL teachers in Poland regarding pronunciation teaching.

Abstract

up to date information systems collect data from technological process, facts about production, reproduction and health of animals. On the base of all figures of these measurable values and evaluation of observable characteristics we can do the classification of the total rate of animal welfare. Physical activity of animals is affected by many factors during the day, especially satisfying basic needs, i.e. feed intake, social manifestations, etc. Vitalimeter is recording physical activity of the animal, including the type of movement, standing and lying time, number of leap.

Abstract

A total of 131 species of Sciaridae are recorded from the Gemer region in central Slovakia. The material was obtained in the years 2008-2012 by means of Malaise traps and by individual collecting by the junior author. Fifty-one species are recorded as new to Slovakia including 4 undescribed species, which will be treated in separate publications

Abstract

Iranian long legged wood frog, Rana pseudodalmatina Eiselt & Schmidtler, 1971 is a brown frog species endemic to the Hyrcanian forest. The objective of the present study is to collect detailed information on the feeding habits of 44 specimens of this species (24 ♂, 20 ♀) by analyzing the stomach contents of individuals from 10 populations inhabiting range. The food habit of R. pseudodalmatina generally varies by the availability of surrounding prey items, and it is a foraging predator, the food of which consists largely of Coleoptera (mainly Carabidae, Dytiscidae and Haliplidae), Diptera (Muscidae) and Hymenoptera (Formicidae), and no difference was found between females and males in the stomach content.

Abstract

Molluscan diversity in selected Protected Landscape Areas (PLA) of Bohemia (Czech Republic) was monitored. For the study, the small-scale PLAs of the Slavkovský Les, the Blanský Les, and the Labské Pískovce were selected. Over 12 500 specimens in total representing 62 mollusc species were found within 2012-2013 by means of hand collecting and sieving the litter layer. To evaluate similarity among the localities, the Jaccard and Sörensen’s indices were calculated. The significance of such data is mainly in their presentation in the available resources such as peer-reviewed scientific journals

On Implicitly Discovered OLAP Schema-Specific Preferences in Reporting Tool

We propose content-based methods for construction of recommendations for reports in the OLAP reporting tool. Recommendations are generated based on preference information in user profile, which is updated implicitly by collecting and analyzing user activity in the reporting tool. Taking advantage of data about user preferences for data warehouse schema elements, existing reports that potentially may be interesting to the user are distinguished and recommended. The approach used for recommending reports is composed of two methods - cold-start and hot-start.

Abstract

A procedure has been developed to collect, transfer, and analyse volatile organic pyrolysis products of tobacco leaf compounds. The volatiles were collected in a series of three traps on adsorbents that also served as substrates for transfer and for introduction of the volatiles into a gas chromatograph. Analytical procedures are described for three gas chromatographic columns packed, respectively, with the three different adsorbents used in the traps. With this system, volatile pyrolyzates were collected and analysed without the use of cryogenic traps, vacuum manifolds, or gas-sampling valves. The applicability of the procedures is demonstrated for the pyrolysis volatiles of stearic acid, a tobacco constituent
