The increase of the air temperatures observed in different European localities during 1951-2010
Střeštík, Jaroslav
Uninterrupted series of annual mean temperatures from 72 European observatories have been processed. The temperature at these stations increased in general more than global temperature, but with considerable fluctuations. The increase at the individual stations is very different. It depends very slightly on the geographic longitude. Stations where lower temperature increase has been observed are located mainly at the Atlantic coast, those with higher increase being mainly in inland. There are, however, many exceptions from this rule, but the gross character of the distribution of stations with different temperature increase seems to be clear.

The status of women on the labour market in Czech Republic
Skopalíková, Anna ; Chytil, Zdeněk (advisor) ; Čermáková, Klára (referee)
The bachelor thesis addresses discrimination of women on the labour market in Czech Republic. Its aim is to verify hypothesises about the existence of lower mean wages of women and about the existence of discrimination of women on the labour market in Czech Republic. Oaxaca wage differential decomposition which is introduced in the theoretical part of the thesis confirmed the existence of wage differentials between the wages of men and women on the Czech labour market, in selected regions and in selected occupational fields. This confirms the hypothesis about lower mean wages of women. Oaxaca wage differentials decomposition also confirms that the wage gap can be explained in most cases up to 18 %. The second hypothesis is confirmed only partially. The discrimination of women probably exists on the labour market but it is not possible to confirm the size of it. The unexplained component of the wage gap (based on the Oaxaca decomposition) includes besides other things the discrimination coefficient. The size of this coefficient is not possible to determine. The secondary aim of the bachelor thesis is to determine the impact of individual variables on the observed wage gaps. Factors which most often influence the wage gaps are education and age.

Clustering and regression analysis of micro panel data
Sobíšek, Lukáš ; Pecáková, Iva (advisor) ; Komárek, Arnošt (referee) ; Brabec, Marek (referee)
The main purpose of panel studies is to analyze changes in values of studied variables over time. In micro panel research, a large number of elements are periodically observed within the relatively short time period of just a few years. Moreover, the number of repeated measurements is small. This dissertation deals with contemporary approaches to the regression and the clustering analysis of micro panel data. One of the approaches to the micro panel analysis is to use multivariate statistical models originally designed for crosssectional data and modify them in order to take into account the within-subject correlation. The thesis summarizes available tools for the regression analysis of micro panel data. The known and currently used linear mixed effects models for a normally distributed dependent variable are recapitulated. Besides that, new approaches for analysis of a response variable with other than normal distribution are presented. These approaches include the generalized marginal linear model, the generalized linear mixed effects model and the Bayesian modelling approach. In addition to describing the aforementioned models, the paper also includes a brief overview of their implementation in the R software. The difficulty with the regression models adjusted for micro panel data is the ambiguity of their parameters estimation. This thesis proposes a way to improve the estimations through the cluster analysis. For this reason, the thesis also contains a description of methods of the cluster analysis of micro panel data. Because supply of the methods is limited, the main goal of this paper is to devise its own two-step approach for clustering micro panel data. In the first step, the panel data are transformed into a static form using a set of proposed characteristics of dynamics. These characteristics represent different features of time course of the observed variables. In the second step, the elements are clustered by conventional spatial clustering techniques (agglomerative clustering and the C-means partitioning). The clustering is based on a dissimilarity matrix of the values of clustering variables calculated in the first step. Another goal of this paper is to find out whether the suggested procedure leads to an improvement in quality of the regression models for this type of data. By means of a simulation study, the procedure drafted herein is compared to the procedure applied in the kml package of the R software, as well as to the clustering characteristics proposed by Urso (2004). The simulation study demonstrated better results of the proposed combination of clustering variables as compared to the other combinations currently used. A corresponding script written in the R-language represents another benefit of this paper. It is available on the attached CD and it can be used for analyses of readers own micro panel data.

Internal equity principle in the context of company strategy
Kopecký, Martin ; Nový, Ivan (advisor) ; Háša, Stanislav (referee) ; Blažek, Ladislav (referee)
The thesis deals with the scientific problem of the link between the strategic management and the compensation system using the principle of internal equity. The work is based on two pillars, namely the qualitative research and own proposed solution. The first part of the thesis describes the qualitative research and the possibilities and the synergistic effects of linking business strategy and compensation system. The qualitative research is performed as a multi-case study and investigates the phenomenon in the practice of three companies from various markets (the Czech Republic, Slovakia and Bosnia and Hercegovina) and industries (finance, IT/Telco and FMCG). The research tries to find answers to the four research questions: How does business strategy influence compensation process? How can compensation support the realization of a business strategy? How can business strategy be linked with a compensation system within the principle of internal equity? How can compensation reinforce the strategic function of the human resources management? The research is based on the study of theoretical sources as well as on practical fieldwork. The qualitative research itself uses qualitative research methods for data collection, such as observations, questionnaires, and document analysis. The population questioned was top managers, line managers and representatives of HR department. In total, 142 interviews were performed by a single person. The collected data were analyzed and the triangulation was applied. The findings were summarized and generalized into a final report that brings answers to the research questions above. The research brings valuable findings used in the second, design part of the thesis. The own proposed solution consists of two main models. The first one is a simplified scheme of the compensation system and the second one is a model of strategic segmentation of jobs. The first model could be used successfully in the business practice as well as in education. The second model of the strategic job segmentation brings answer to the question of synergistic linking of business strategy and the compensation system within the principle of internal equity. The model brings valuable findings and a foundation for further theoretical research and its further development. The model also brings practical solution to the design of related policies and processes in the strategic management of human resources. By the design of both proposed models the main objectives of the thesis were achieved.

Interpersonal relationship development between children's nurse and mother in the neonatology department by means of the H. E. Peplau model
AMBROŽOVÁ, Helena
The dissertation objective on the theme {\clqq}Interpersonal relationship development between children's nurse and mother in the neonatology department by means of the H. E. Peplau model`` is to chart individual phases utilization in the process, professional relationship development between children´s nurse and mother according to the H. E. Peplau model. Further through created documentation to find out differences at the approaches during professional relationship connecting between children´s nurse and mother in the neonatology department in the Hospital JSC in České Budějovice. To meet these objectives the dissertation is divided into theoretical part which focuses on differences at the care of developed and underdeveloped infant, nursing model H. Peplau including its application into practice. The second, practical part is divided into quantitative and qualitative parts. The quantitative part concentrates on factors finding out which influence professional relationship between children´s nurse and mother in compliance with the H. E. Peplau model and concurrently specifies individual nurse roles changing during professional relationship children´s nurse and mother. The data of the quantitative research part have been learned by means of questionnaire disquisition. By the dissertation results summarizing I found out facts regarding H. E. Peplau model individual phases utilization at the children nurse {--} mother relationship establishing in neonatology. Hypothesis 1 {\clqq}Children nurses with own children establish faster the professional relationship with mother`` {--} has come true. Hypothesis 2 {\clqq}Children nurse practice length influences the ability to establish the professional relationship with mother`` {--} has come true. Hypothesis 3 {\clqq}Children nurses undertake the role of the mentor in most cases`` {--} hasn´t come true. The data of the qualitative research part were identified by observation, conversation with children nurse, creating of the documentation own proposal at the mothers of prematured children hospitalized by ROOM IN system and its application in practice. Mothers were divided into two groups, the common way of the interpersonal relationship establishing with mother was used in the first group, the way of the interpersonal relationship establishing with mother according to the H. E. Peplau model was applied in the second one. At the quasiexperiment it has been identified the interpersonal relationship establishing with mother proceeds better at the nursing H. E. Peplau model utilisation. The dissertation knowledge can be partly utilised by neonatology department of the Hospital JSC in České Budějovice, in particular by children nurses to master the abilities for professional relationship establishing with mother and to provide subsequently mother and child with the complex nursing care. Further to students and other interested people in this issue.

ELECTRON BEAM REMELTING OF PLASMA SPRAYED ALUMINA COATINGS
Matějíček, Jiří ; Veverka, J. ; Čížek, J. ; Kouřil, J.
Plasma sprayed alumina coatings find numerous applications in various fields, where they enhance the properties of the base material. Examples include thermal barriers, wear resistance, electrical insulation, and diffusion and corrosion barriers. A typical structure of plasma sprayed coatings, containing a multitude of voids and imperfectly bonded interfaces, gives them unique properties - particularly low thermal conductivity, high strain tolerance, etc. However, for certain applications such as permeation barriers or wear resistance, these voids may be detrimental.\nThis paper reports on the first experiments with remelting of plasma sprayed alumina coatings by electron beam technology, with the purpose of densifying the coatings and thereby eliminating the voids. Throughout the study, several parameters of the e-beam device were varied - beam current, traverse velocity and number of passes. The treated coatings were observed by light and electron microscopy and the thickness, structure and surface morphology of the remelted layer were determined and correlated with the process parameters. Based on the first series of experiments, the e-beam settings leading to dense and smooth remelted layer of sufficient thickness were obtained. In this layer, a change of phase composition and a marked increase in hardness were observed.\n

Sorption and Stabilization of Metals/Mettalloids by Innovative Synthesized Sorbent Amochar.
Ouředníček, P. ; Trakal, L. ; Komárek, M. ; Pohořelý, Michael
Remediation of contaminated soil which is based on stabilization and immobilization of potential\nhazardous substance by sorption materials has been studied intensively nowadays. Biochar – activated organic carbon belongs to this group of stabilizing agents which can adsorb wide range of contaminants, including metals/metalloids. Surface area of the biochars is quite large in general and functional groups (e.g. COO–) can form chelates or alkaline elements on the surface, which is represented by cation exchange capacity. Altogether with the high pH values (7.00 – 10.00), biochars are quite effective sorbents and can adsorb metals/metalloids from the solution (ground water), especially in acidic soils (in the environments affected by intensive mining activities). Sorption\neffectiveness can be increased (especially for As (V) or Cr (VI) sorption) by modification of biochar by various types of secondary oxides. Innovative sorbent AMOchar (AMO + biochar) has been synthesized currently. The product was prepared by adding of biochar to the reaction solution during amorphous manganese oxide (AMO) synthesis. The AMOchar was formed mainly by Mn-oxalates which had coated surface of the pristine biochar. AMOchar composite was able to remove significantly higher amounts of various metal(loid)s from the solution despite the rather high pH of the material. Sorption effectiveness was high not only in case of Pb (II) sorption (almost 99%), and Cd(II) (51.2%), but also a very high amount of As(V), 91.4%. Additionally, both AMOchar composite was able to reduce Mn leaching. This can avoid potential post-contamination caused by the dissolution of less stable Mn-oxalates as observed in the pure AMO.
