STIMULATION OF EXECUTIVE FUNCTION 'SHIFTING' IN TEACHING MATHEMATICS

Executive functions are mental processes which manage, control and organise human cognition. They represent the fundamental level of mental functioning. The research team from the Faculty of Education, University of Presov is designing a comprehensive program for stimulation of executive functions of pupils aged 9-10 years within the APVV project scheme. Three executive functions: inhibition, working memory and shifting were specified to be stimulated by the program. Mathematical component of the program is focused on stimulating and reinforcing pupil's executive functioning on the background of mathematical curriculum. This paper provides an outline for designing tasks aimed at stimulating the executive function of shifting. Shifting is the ability to switch fluently between multiple sets of cognitive operations. The authors also propose the guidelines for assessing and interpreting the performance of pupils in such tasks.
Bibliometric Approach to Research Assessment : Publication Count

We investigated how bibliometric indicators such as publication count and citation count affect the assessment of research performance by computing various bibliometric scores of the works of Korean LIS faculty members and comparing the rankings by those scores. For the study data, we used the publication and citation data of 159 tenuretrack faculty members of Library and Information Science departments in 34 Korean universities. The study results showed correlation between publication count and citation count for authors with many publications but the opposite evidence for authors with few publications. The study results suggest that as authors publish more and more work, citations to their work tend to increase along with publication count. However, for junior faculty members who have not yet accumulated enough publications, citations to their work are of great importance in assessing their research performance. The study data also showed that there are marked differences in the magnitude of citations between papers published in Korean journals and papers published in international journals.
The Internet Effects on Sex Crime and Murder – Evidence from the Broadband Internet Expansion in Germany

This paper studies the effects of the introduction of a new mass medium on criminal activity in Germany. The paper asks the question of whether highspeed internet leads to higher/lower sex crime offences and murder. I use unique German data on criminal offences and broadband internet measured at the municipality level to shed light on the question. In order to address endogeneity in broadband internet availability, I follow Falck et al. (2014) and exploit technical peculiarities at the regional level that determine the roll-out of high-speed internet. In contrast to findings for Norway (Bhuller et al., 2013), this paper documents a substitution effect of internet and child sex abuse and no effect on rape incidences. The effects on murder increase under the instrumental variable approach however remain insignificant. Overall, the estimated net effects might stem from indirect effects related to differences in reporting crime, a matching effect, and a direct effect of higher and more intensive exposure to extreme and violent media consumption. After investigating the potential channel, I do find some evidence in favor of a reporting effect suggesting that the direct consumption effect is even stronger. Further investigation of the development of illegal pornographic material suggests that the direct consumption channel does play a significant role in explaining the substitution effect.
Redshift measurement of Fermi Blazars for the Cherenkov Telescope Array

Blazars are active galactic nuclei, and the most numerous High Energy (HE) and Very High Energy (VHE) gamma-ray emitters. Their optical emission is often dominated by non-thermal, and, in the case of BL Lacs, featureless continuum radiation. This renders the determination of their redshift extremely difficult. Indeed, as of today only about 50 % of gamma-ray blazars have a measured spectroscopic redshift. The knowledge of redshift is fundamental because it allows the precise modeling of the VHE emission and also of its interaction with the extragalactic background light (EBL). The beginning of the Cherenkov Telescope Array (CTA) operations in the near future will allow the detection of several hundreds of new BL Lacs. Using the first Fermi catalogue of sources above 10 GeV (1FHL), we performed simulations which demonstrate that at least half of the 1FHL BL Lacs detectable by CTA will not have a measured redshift. Indeed the organization of observing campaigns to measure the redshift of these blazars has been recognized as a necessary support for the AGN Key Science Project of CTA. Taking advantage of the recent success of an X-shooter GTO observing campaign, we thus devised an observing campaign to measure the redshifts of as many as possible of these candidates. The main characteristic of this campaign with respect to previous ones will be the use of higher resolution spectrographs and of 8 meter class telescopes. We are starting submitting proposals for these observations. In this paper we will briefly describe the selection of the candidates, the characteristics of these observation and the expected results.
In-duct circumferential acoustic mode measurement of axial fan/compressor

In-duct circumferential acoustic mode of a single stage fan was measured using equidistant microphone array with high back ground noise and high rigid wall reflection.Primary circumferential acoustic mode amplitude was obtained by utilizing the cross-correlated(CC)reference channel mode detection technique and the conventional root mean square-averaging(RMS)mode detection technique.The results were compared with Tyler and Sofrin's duct mode theory,finding that both CC mode detection technique and RMS mode detection technique can obtain the ideal mode detection results with high back ground noise and high rigid wall reflection,and the mode amplitude of the former was lower than that of the latter.This is because CC mode detection technique decreases the impact of random noise on the mode amplitude.It is also found that the error of mode amplitude from CC mode detection technique is lower than 1dB when the number of microphone in the circular microphone array is more than four times of the circumferential acoustic mode order.
Photocatalytical Decomposition of Contaminants οn Thin Film Gas Sensors

Gas sensing materials have been prepared in a form of TiO2–SnO2 thin films by rf reactive sputtering from Ti:SnO2 and Sn:TiO2 targets. Material studies have been performed by scanning electron microscopy, atomic force microscopy, X-ray diffraction at grazing incidence, Mössbauer spectroscopy, X-ray photoelectron spectroscopy and optical spectrophotometry. Dynamic gas sensing responses have been recorded as reproducible changes in the electrical resistance upon introduction of hydrogen at a partial pressure of 100–6000 ppm over a wide temperature range 473–873 K. Contamination experiments have been carried out with the motor oil (40 vol.% solution in CCl4) in order to study the effect of UV light illumination on the gas sensor response. Optical spectroscopy has been applied to monitor the photodecomposition of the test compound, bromothymol blue. The Electronic Nose, ALPHA MOS FOX 4000 has been used in order to differentiate between different groups of motor oil vapors.
Impact of dust deposition on carbon budget: a tentative assessment from a mesocosm approach

By bringing new nutrients and particles to the sur- face ocean, atmospheric deposition impacts biogeochemi- cal cycles. The extent to which those changes are modify- ing the carbon balance in oligotrophic environments such as the Mediterranean Sea that receives important Saharan dust fluxes is unknown. The DUNE (DUst experiment in a low Nutrient, low chlorophyll Ecosystem) project provides the first attempt to evaluate the changes induced in the carbon budget of a large body of oligotrophic waters after simulated Saharan dust wet or dry deposition events, allowing us to measure (1) the metabolic fluxes while the particles are sink- ing and (2) the particulate organic carbon export. Here we re- port the results for the three distinct artificial dust seeding ex- periments simulating wet or dry atmospheric deposition onto large mesocosms (52 m 3 ) that were conducted in the olig- otrophic waters of the Mediterranean Sea in the summers of 2008 and 2010. Although heterotrophic bacteria were found to be the key players in the response to dust deposition, net primary production increased about twice in case of simu- lated wet deposition (that includes anthropogenic nitrogen). The dust deposition did not produce a shift in the metabolic balance as the tested waters remained net heterotrophic (i.e., net primary production to bacteria respiration ratio < 1) and in some cases the net heterotrophy was even enhanced by the dust deposition. The change induced by the dust addi- tion on the total organic carbon pool inside the mesocosm over the 7 days of the experiments, was a carbon loss dom- inated by bacteria respiration that was at least 5-10 times higher than any other term involved in the budget. This loss of organic carbon from the system in all the experiments was particularly marked after the simulation of wet deposition. Changes in biomass were mostly due to an increase in phy- toplankton biomass but when considering the whole partic- ulate organic carbon pool it was dominated by the organic carbon aggregated to the lithogenic particles still in suspen- sion in the mesocosm at the end of the experiment. Assum- ing that the budget is balanced, the dissolved organic carbon (DOC) pool was estimated by the difference between the to- tal organic carbon and the particulate organic carbon (POC) pool. The partitioning between dissolved and particulate or- ganic carbon was dominated by the dissolved pool with a DOC consumption over 7 days of 1 µmol C L 1 d 1 (dry
Cytological Features of the Normal Ear Canal of Wild Jackals (Canis aureus) and Domesticated Dogs (C. domesticus)

This is the first reported study in which various cytological and microbial components of the ear canal of wild jackals (Canis aureus) were examined and compared with those of domesticated dogs (C. domesticus). It is proposed that the differences between them might be attributable to domestication. The normal cytology of the jackals' ears includes cerumen, keratinous debris, coccoid bacteria and yeast-like organisms similar to domesticated dogs, but the frequencies of these findings differed significantly between the two species. In the jackals the incidences of ceruminous debris and yeasts were significantly lower (p p = 0.004 respectively), while keratinous debris and coccoid bacteria were significantly higher (p < 0.001). During domestication some changes have probably occurred in the dogs' lifestyle that predisposed them to the growth of yeasts in their ears but less to bacterial growth. It is possible that the higher numbers of bacteria might be a result of environmental contamination, because some of the jackals lived near urban centers and feed on garbage.
Electrical system for wavefarm

Electrical power production through renewable energy sources has gained importance over last few decades due to depleting natural resources and increasing concerns about green energy. Replacing the use of fossil fuels, coal, oil, and natural gas; renewable energy sources can deliver the growing demand of electricity. Wave energy is one of the emerging and promising renewa-ble energy source that can potentially contribute in delivering electrical power. In this project electrical design of a wavefarm comprising of various wave energy converters was proposed. In this regard the design of wave energy converter (Wave El Buoy) was studied. Eco-nomically and practically feasible design is selected for a single buoy unit. Performance of Wave El Buoy was evaluated by considering Synchronous reluctance generator and full power fre-quency converter. Standard components were employed to achieve cost effectiveness ensuring the system reliability. Additionally, the integration of this system into the floating transformer hub considering various radial schemes was investigated based on performance and economics. This included power loss evaluation of the transmission network and the voltage drop over each radial scheme. Optimal design with lowest power loss and voltage drop was selected and pro-posed. Lastly in this project, in order to understand the potential of wave energy, a comparison was made between a wavefarm and a windfarm in terms of power density.
Processed Food Trade of Greece with EU and Non-EU Countries: An Empirical Analysis

This paper examines the implications of the European Union (EU) regional trade preferences for processed food trade between Greece and its EU partners, and between Greece and non-EU countries. The empirical analysis relies on the gravity model, and uses different estimation techniques. The results show that the EU regional trade preferences led to substantial increases in processed food trade between Greece and its EU partners, emphasizing trade creation effects. The magnitudes of these increases are higher than the intra-EU average, and are more pronounced for Greece’s imports than for Greece’s exports. The results also indicate that the EU regional trade preferences brought about decreases in processed food trade between Greece and non-EU countries, implying trade diversion effects. The findings in this paper suggest that the Greek food processing industry would benefit from enhanced production, innovation, and market strategies to expand exports to the EU market and to counter import competition in the domestic market.
Effect of Capital Structure on the Performance of Listed Consumer Goods Companies in Nigeria

Managers of corporate entities are mostly in a confrontation with the problem of; what combination of capitalstructure (equity and debt) will maximizereturns and value of their firms? The study,therefore, aims at assessing the effect of capital structure on the financial performance of listed Consumer goodscompanies in Nigerian. All consumer goods companies quoted on the NigerianStock Exchange are considered the population for this study while seven (7) out of these firms whose accounting year-ends31 December are considered as the sample.Secondary data was utilized from theannual financial reports of the sampled firms from the year 2008 – 2013, which was obtained from African Financial websiteand official website of Nigerian Stock Exchange. The study used ex-post factoresearch design to examine the relationship between independent and dependentvariables while controlling for other variables. Descriptive statistics, correlation, and hierarchical multipleregression analyzes were carried out to test the hypothesesdeveloped in the study. The study found that there is a positive and significant relationship between firm’s capitalstructure and corporate financial performance. The study specifically foundthat short-term debt (STD) has no significance positive effect on return onequity (ROE) while Long-term debt (LTD) has positive relation and significantlyeffect on ROE. The study recommends that firms should consider the mixture ofequity and debt since they are major determinants of corporate performance.Authorities concerned should create an enabling business environment forcompanies (especially those with low capital) so as to have access to long-term debt to finance their operations andimprove performance in the short-run, instead of using high short-term debts,to cushions for financing and profitability problems.Keywords:Capital Structure, Firm Performance, Short-term debt, Long-term debt,Return on Equity
Exploring the Diffuse X-ray Emission of Supernova Remnant Kesteven 69 with XMM-Newton

We have investigated the X-ray emission from the shock-heated plasma of the Galactic supernova remnant Kesteven 69 with XMM-Newton. Assuming the plasma is at collisional ionization equilibrium, a plasma temperature and a column absorption are found to be kT ~ 0.62 keV and respectively by imaging spectroscopy. Together with the deduced emission measure, we place constraints on its Sedov parameters.
Comparative Study on Antimicrobial Activity of Vitex negundo var. negundo and Vitex negundo var. purpurascens

The present study was conducted with an aim of determining antimicrobial activity of Vitex negundo var. negund o (Vnvn) and Vitex negundo var. purpurascens (Vnvp). The powdered leaf materials of both varieties were extracted using methanol in soxhlet assembly. The content of total phenolics and flavonoids were estimated by Folin-Ciocalteau reagent and Aluminium chloride colorimetric estimation method respectively. Antibacterial activity of extracts was determined against five drug resistant urinary tract pathogens by agar well diffusion assay. Poisoned food technique was performed to determine antifungal effect of extracts. The extracts caused concentration dependent inhibition of urinary tract isolates. Marked antibacterial effect was shown by extract of Vnvp. Among bacteria, Staphylococcus aureus and Klebsiella pneumoniae were inhibited to high and least extent respectively by extracts. The extracts were effective in inhibiting test fungi as revealed by reduction in mycelial growth in plates poisoned with extracts. Here also, high inhibitory activity was observed in case of extract of Vnvp. Among fungi, Helminthosporium sp. , Alternaria sp. , and C. capsici displayed similar susceptibility to both extracts at concentration 1mg/ml. Aspergillus flavus was inhibited to least extent by extracts. Phytoconstituents viz., tannins, alkaloids, flavonoids, saponins, steroids and glycosides were detected in extract of both Vnvn and Vnvp. The total phenolic and flavonoid contents were high in extract of Vnvp. The extracts were effective against bacteria and fungi. The presence of high phenolic and flavonoid content could be ascribed to the marked inhibitory activities of the extract of Vnvp.

Debye Screening Effect on Scaling Behavior of Longest Relaxation Time of Biological Polyelectrolyte Chain

The scaling relationship of the longest relaxation time of a single chain of semiflexible biological polyelectrolyte has been investigated by performing well-established coarse-grained Brownian dynamics simulations. Two kinds of longest relaxation times were estimated from time-sequences of chain trajectories, and their behaviors were interpreted by applying the scaling law for different molecular weights of polyelectrolyte and Debye lengths. The scaling exponents for longest stress relaxation and rotational relaxation are found in the ranges of 1.67-1.79 and 1.65-1.81, respectively, depending on the physicochemical interaction of electrostatic Debye screening. The scaling exponent increases with decreasing screening effect, which is a special feature of polyelectrolytes differing from neutral polymers. It revealed that the weak screening allows a polyelectrolyte chain to follow the behavior in good solvent due to the strong electrostatic repulsion between beads.

The Effect of Scale-Dependent Habitat Gradients on the Structure of Bird Assemblages in the Czech Republic

Abstract. Spatial patterns in bird community structure are closely related to changes in habitat composition at small spatial scales, but the explanatory power of habitat declines towards larger scales, where dispersal limitations and historical factors becoming more important. To disentangle these effects, we performed a large-scale bird census using a small-scale field approach in the Czech Republic. Using canonical correspondence analysis, we found that the strongest scale-independent gradient in bird community composition goes from higher-altitude forest assemblages to lower-altitude farmland and human settlement assemblages. The other gradients were also scale-dependent, probably due to the different distributional patterns of particular habitats at the respective scales. Closer examination of bird occurrence in particular habitats revealed that water bodies host the most distinct bird assemblage compared to the assemblages of other habitats. Interestingly, although the census tracked the most important east-west biogeographical gradient within the Czech bird fauna, we did not find longitude to be a significant predictor of changes in bird community structure along the transect at any resolution. We suggest that the biogeographical gradient is actually related to the habitat-based distinction between the coniferous-forested higher-altitude West and the deciduous-forested lower-altitude agricultural East. Fine-scale bird-habitat associations are thus responsible for the patterns of community structure at all spatial scales.
