Children’s Initiations in Communication with Preschool Teachers
Authors: Navrátilová Hana 
Published: September 2017

Abstract
Introduction: This paper deals with an important aspect of preschool teachers’ everyday professional life - interacting with children during educational activities in kindergarten environment. The research of real situations in kindergarten, still rare in Czech pedagogical discourse, indicates the limitedness of preschool teachers’ communication following already fixed communication structures and patterns. There is not much evidence that teacher-child communication in kindergarten is initiated by children with any frequency. The aim of our research study is to describe preschool children’s initiations in communication with preservice preschool teachers and identify teachers’ strategies in mutual communication. Methods: The research is based on qualitative analysis of data obtained through participated unstructured observation (37 video recordings of micro educational situations with the duration of 3 to 15 minutes were collected) and written reflection of pre-service preschool teachers (55 participants). Each part of the observation took place in a different class of a standard kindergarten. In one case, it was a homogeneous class of children aged 5-6 years, and in the second, a heterogeneous class with children aged between 3 and 5 years. Our data material in the form of written reflections and transcribed video recordings was then processed through the qualitative content analysis. Results: Research results show children breaking the communication structure managed by the teacher, and the teacher’s strategies in these situations. We identified five main circumstances of preschool children’s initiations as communicating their own experiences or associations related to the topic presented by the teacher. Discussion: Our findings show a certain range of responses of future teachers to children’s initiation in interaction during educational activities. Besides evidence of releasing communication in terms of teacher management, less suitable kinds of responses to children’s initiation appear. The teacher is not able to give up control over the ongoing communication. Limitations: Selected research sample consists of pre-service teachers, who represent only a partial sample of potential interactions in the kindergarten environment. Thus, to some teachers, the findings apply only partially in practice; with other teachers, we could possibly expand our research even deeper. This choice to use only a partial sample reflects both practicality and the need to improve the competence of future teachers through recording their unscripted interactions with children. Conclusions: Children need teachers who are sensitive to their initiations and offer space for children to initiate communication. If we want to have students at the primary and secondary levels of education with developed life skills and the ability to discuss and argue, we need to offer such manner of communication as early as in kindergartens.

Published: September 2017

Abstract
Introduction: The text presents the results of a study conducted in the years 2015 - 2016. The objective of the study was to examine a programme of physical activities aimed at developing children’s social skills. Methods: The research was conducted in a kindergarten. This was a deliberate choice on the basis of availability. The experimental group comprised of 24 children, the control group comprised of 11 children. A 12-lessons programme of physical activities was applied, with a frequency of 1 lesson per week. Entry and exit measurements were taken before the commencement of the programme and after its end, with the help of structured observation, CATO projective tests and interviews with teachers. The data were processed by means of a descriptive statistics level by comparing the average levels. The achieved changes in the level of social skills were subsequently displayed through percentage values. Results: The results indicate that physical activities have a positive effect on the development of children’s social skills. Although the changes are not significant, the experimental group recorded greater changes than the control group in all the evaluated areas; in terms of the overall results, it was actually more than twofold. Discussion: The results cannot be generalized. The results are only valid for our group of children. The reason is the insufficient size of the research sample. Limitations: A significantly limiting factor showed to be the low number of children in the control group. This caused a lack of balance between the two groups in terms of the number of children and their entry level. The length of the intervention program was another limit. Conclusions: Despite the limits of the study, the authors view the results as positive. The reason is the improvement in all the children’s social skills in all the monitored areas, and the more than twofold improvement by the experimental groups compared to the control group.
Study Circles in Online Learning Environment in the Spirit of Learning-Centered Approach
Authors: Simándi Szilvia 
Published: September 2017

AbstractIntroduction: In the era of information society and knowledge economy, learning in non-formal environments gets a highlighted role: it can supplement, replace or raise the knowledge and skills gained in the school system to a higher level (Forray & Juhász, 2008), as the so-called “valid” knowledge significantly changes due to the acceleration of development. With the appearance of information technology means and their booming development, the possibilities of gaining information have widened and, according to the forecasts, the role of learning communities will grow. Purpose: Our starting point is that today, with the involvement of community sites (e.g. Google+, Facebook etc.) there is a new possibility for inspiring learning communities: by utilizing the power of community and the possibilities of network-based learning (Ollé & Lévai, 2013). Methods: We intend to make a synthesis based on former research and literature focusing on the learning-centered approach, online learning environment, learning communities and study circles (Noesgaard & Ørngreen, 2015; Biggs & Tang, 2007; Kindström, 2010) Conclusions: The online learning environment can be well utilized for community learning. In the online learning environment, the process of learning is built on activity-oriented work for which active participation, and an intensive, initiative communication are necessary and cooperative and collaborative learning get an important role.
Family as One of the Most Important Factors in a Child’s Upbringing
Authors: Oberuč Jaroslav , Zapletal Ladislav 
Published: September 2017

Abstract
Introduction: The development of a child takes place according to certain laws, each one of which has its own individual dynamics, so, every child becomes a unique human being. Children gradually collect information about themselves and the world around them. They receive feedback about themselves from people who take care of them - mainly their family, mother and father. Their positive responses support the child’s feeling of being loved, worthy of interest, which has a positive effect on them. Purpose: Family environment is likely to have the strongest impact on the child’s behaviour. Educational procedures, family climate, relationships between parents, those between parents and the child, the degree and methods of satisfying the child’s needs, moral values, and social ties of the family - they all affect the child’s behaviour. Methods: In the presented paper, traditional desk research methods were used. Conclusions: Behaviour is learned and has its purpose. Family teaches the child many things, e.g. how to cope with simple tasks, as well as about complex social inclusion.

Abstract
The study aimed at assessing the levels of polychlorinated biphenyls (PCBs) concentration in Orogodo River Sediments at Agbor, Delta State, Nigeria. Sixteen sediment samples at different sample point were collected and analyzed; obtained concentrations were compared with exiting standards. Sediment samples were extracted using a mixture of hexane and acetone (1:1), sonicated in an ultrasonic bath (15 min) and placed on a shaker for two hours. Chromatographic analysis was done after solvent exchange, was carried out on the final extract using n-hexane (1000 μl) and injected (1 μl) into a gas chromatographic system coupled with an electron capture detector (ECD). Results from this study revealed that the concentration of PCBs in all the sediment samples under investigation was highest with 0.198 μg/kg in the Agric yard Agbor 2 sample point and lowest with 0.026 μg/kg in the Behind Prison - Agbor 1. The concentration of PCBs for all the sediment samples analyzed ranged in the order: Agric Yard Agbor 2 < Slaugther Agbor 2 < River Ama 1 < Mr. Biggs Agbor 1 < Behind Prison Agbor 2 < River Ama 2 < Mr. Biggs Agbor 3 < Under Bridge Agbor 1 < Mr. Biggs Agbor 2 < River Ama 4 < Agric Yard Agbor 1 < Mr. Biggs Agbor 4 < SlaugtherAgbor 1 < River Ama 3 < Under Bridge Agbor 2 < Behind Prison Agbor 1. The obtained results in this study suggest the urgent need to establish a program for monitoring organochlorine pollutants in our rivers and sediment in other to curb any elevation in concentration of pollutants over the environmental quality standards and appropriate actions taken.

Abstract
Highly ordered TiO2 nanotube (TiO2 NT) arrays were prepared by anodic oxidizing method on the surface of the Ti substrate. Nitrogen-doped TiO2 nanotube (N-TiO2 NT) arrays were carried out by ammonia solution immersion, and Ag nanoparticles loaded N-doped TiO2 nanotube (Ag/N-TiO2 NT) arrays were obtained by successive ionic layer adsorption and reaction (SILAR) technique. The samples were characterized by the X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), field emission scanning electron microscopy (FESEM), high-resolution transmission electron microscopy (HRTEM), photoluminescence (PL) emission spectra, ultraviolet–visible (UV–vis) diffuse reflectance spectroscopy (DRS). The result indicated that the diameter and wall thickness of the TiO2 NT are 100–120 and 20–30 nm, respectively. Moreover, the morphology and structure of the highly ordered TiO2 NTs were not affected by N-doping. Furthermore, Ag nanoparticles were evenly deposited on the surface of TiO2 NTs in the form of elemental silver. Finally, the photocatalytic activity of Ag/N-TiO2 NTs was evaluated by degradation of methyl orange (MO) under visible-light irradiation. The Ag/N-TiO2 NTs exhibited enhanced photocatalytic properties, which could reach 95% after 90-min irradiation.

Abstract
This paper presents the experimental and numerical analysis of the potential of a braided fabric for flexor tendon repair. Numerical models of tubular braided fabrics were generated using a python script interface and imported into ABAQUS® while Flexor tendon models were represented as silicone rubber rods. Experimental tests and Finite Element Modelling (FEM) of the flexor tendon repair was undertaken by deploying two tendon ends from opposite sides of a tubular braided fabric. This was done such that the tendon ends meet at the midpoint within the fabric. The tendons were tightly held to emulate a realistic repaired tendon. A displacement driven uniaxial loading was induced on the tendon-fabric assembly sufficient to cause a 2mm gap between the tendon ends. Numerical analysis of the repair potential of a braided fabric in tendon repair was done by analyzing selected fabric parameters that were crucial in tendon repair applications. The results show that changing the parameters of the braided fabrics significantly affected the potential of the fabrics during tendon repair.

About the Greek origin of acarology: a short note onArgasand the Acari
Authors: Zaborowski Robert , Daszkiewicz Piotr 
Published: September 2017

AbstractThe article presents the etymology and Greek roots of two terms in modern acarology. The origin of acarological nomenclature is analysed in the context of Homer’sOdysseyand Aristotle’sParts of AnimalsandHistory of Animals. The Greek concept of the smallest animals “acari” as indivisible has been influencing European culture for centuries. The article shows the influence of the Greek tradition on zoology in the 18thcentury, at the time of birth of modern acarology. The works of French naturalists, the founders of this science, are analysed in this context.
Diversity and significance of eriophyoid mites (Acari: Eriophyoidea) associated with coniferous trees in Poland: a review
Authors: Kiedrowicz Agnieszka , Lewandowski Mariusz , Skoracka Anna 
Published: September 2017

Abstract
Among the approximately 200 eriophyoid mite species associated with coniferous trees worldwide, 33 species (of the families Eriophyidae and Phytoptidae) infest conifers in Poland, and 24 of them can cause visible feeding symptoms. In this paper we discuss the importance of eriophyoid mites to coniferous plants in Poland and their potential impact on the decorative value of ornamental plants. We emphasize the general lack of knowledge about the diversity of eriophyoid mites associated with coniferous trees and its role in the management and control of this economically important mite group.
Microhabitats and oribatid fauna: comparison of 2 sampling approaches
Authors: Skubała Piotr 
Published: September 2017

AbstractOribatid fauna highly varies among habitats, but different microhabitats within a habitat are also characterized by different mite species. The main goal of the research was to compare the observed structure of an oribatid community when samples were collected at random from the soil-litter layer of 0-10 cm in depth (standard approach) and selectively from 6 types of available microhabitats (complex approach). Samples were taken within a small plot (10 m × 10 m) in a forested area of the Silesian Park (Chorzów, south Poland). Overall, 2642 specimens of Oribatida belonging to 62 species were collected in 66 samples. The structure of the oribatid community observed by means of the 2 sampling approaches was completely different. The abundance and species richness of oribatid mites collected from 6 microhabitats were significantly higher than in the soil-litter layer alone. Results of this study show that random collecting of only soil-litter samples may reduce the evaluation of species richness in a study area by 40%. Each of the studied microhabitats supported a peculiar oribatid fauna.
Cyst morphology of large branchiopod crustaceans (Anostraca, Notostraca, Laevicaudata, Spinicaudata) in western Poland
Authors: Czyż Michał Jan , Woliński Paweł , Gołdyn Bartłomiej 
Published: September 2017

AbstractThe morphology of resting eggs was studied in Polish populations of 7 large branchiopod species:Branchipus schaefferi,Chirocephalus shadini,Eubranchipus grubii(Anostraca),Lepidurus apus,Triops cancriformis(Notostraca),Lynceus brachyurus(Laevicaudata), andCyzicus tetracerus(Spinicaudata). Scanning electron microscope photographs for each species are also provided. In some species (especiallyE. grubii), the ornamentation and size of cysts from Polish populations significantly differ from literature data for populations from other parts of Europe. We also present a key to determination of the studied species based on cyst morphology and discuss whether those traits are useful in surveys of new localities of endangered large branchiopods.
Effects of green algae and napa cabbage on life-history parameters and gut microflora ofArchegozetes longisetosus(Acari: Oribatida) under laboratory conditions
Authors: Seniczak Anna , Ligocka Anna , Seniczak Stanisław , Paluszak Zbigniew 
Published: September 2017

AbstractWe compared the effect of green algae (dominated byProtococcussp.) and the earlier studied napa cabbage on the life-history parameters and gut microflora of the oribatid miteArchegozetes longisetosus(a chelicerate model organism). Napa cabbage contained more crude ash, protein, and crude fibre than green algae, butA.longisetosusdeveloped better on the latter food, displaying higher fertility, lower mortality of offspring and shorter development than on napa cabbage. The gut microflora ofA.longisetosusdepended on the kind of food and developmental stage of this mite. The adults fed with napa cabbage had more abundant and more active microflora than those fed with green algae, whereas in the tritonymphs the microflora was more abundant when they were fed with green algae, and was more active in the group fed with napa cabbage. Irrespective of the treatment, the highest percentage of the isolated bacteria were gram-positive bacilli or gram-negative bacteria, but the mites feeding onProtococcussp. contained no cocci, whereas those fed with cabbage had no gram-positive bacteria.
Spatial Aspects Of Unemployment In The Visegrad-Group Economies
Authors: Formánek Tomáš , Hušek Roman 
Published: September 2017

Abstract
Purpose of the article: Most regional macroeconomic processes may not be adequately analyzed without accounting for their spatial nature: regional distances, interactions between neighbors, spill-over effects and interdependencies. This contribution focuses on various factors ruling unemployment dynamics in the Visegrad Group countries and their major economic partners: Germany and Austria. The analysis is performed at the NUTS2 level. Methodology/methods: Spatial econometrics is a unique tool for a broad range of quantitative analyses and evaluations. Spatial econometric models are based on geo-coded (spatially defined) data. Spatial econometrics and regional competitiveness paradigms are combined into different types of regression model specifications describing unemployment dynamics. Alternative spatial structures (i.e. neighbor definitions) are used for verification of stability in estimated model properties. Scientific aim: We aim to provide a detailed empirical evaluation of spatially determined factors of regional unemployment dynamics, along with insight into the robustness of such approach. Both conceptually and parametrically varying neighbor definitions are used to provide evidence for model evaluation. Findings: We find strong positive spatial dependence patterns in the estimated models, robust against varying neighborhood definitions. Our results strongly support the importance of regional and potentially cross-border (international) cooperation in macroeconomic policies addressing unemployment. The estimated models also underline the importance of using spatial models, by pointing out the bias in OLS-estimated models. Conclusions and limits: Spatial approach to econometric analysis provides important insight and robustness to a broad range of unemployment analyses that may be carried out using regional (spatial) data. At the same time, it should be noted that this article focuses mostly on the spatial and stability aspects of model estimation, while leaving out other interesting topics such as spill-over effects calculations as based on estimated models. Also, estimations provided in this article might benefit from spatial panel data-based methods - once data availability issues are sorted.
Die Auswirkungen Der Zinspolitik Im Bankensystem Und Bei Immobilienentwicklungen / The Impact Of Interest Rate Policy, On The Banking System And On Real Estate Development
Authors: Priess Pamela 
Published: September 2017

Abstract
The research purpose is to find out if signs of a real estate bubble are shown at the austrian real estate market right now. Lending rates are composed of different factors: the base rate is the price that the customer is willing to pay. The risk premium is given to compensate the lenders risk of full or partial failure of repayment. The inflation adjustment takes into account the impairment of money over the term of a loan. The liquidity premium increases with extension of the term of the loan. The European Central Bank influences the interest rate policy by varying the interest for money saved there by the banks. At the moment there are used negative interest rates, i.e. penalty interest. The methodology used was that recently the ECB lowered the interest rates which might cause real estate bubbles and, subsequently, banks and economic crises may follow, if interest rates were to be increased again sooner or later. Therefor the author studied the amount of sales and the connection to the interest rates and the interest rate policy of the banks right now. Summarizing it can be seen that in Kittsee, an Austrian area with a lot of real estate sales, as an example, 565 real estate properties were sold in the years 2005 to 2015, the median prices increased in relation to the buyers residence in Austria or non- Austrians at about 375% to 490%, this might indicate signs of change on the market.
