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.

Business plan for setting-up of language school
Kahánková, Andrea ; Chylíková, Hana (advisor) ; Matysová, Kamila (referee)
The aim of this bachelor thesis is to develop a business plan for a set-up of a company specializing in English language tutoring. The theoretical part defines basic rules of doing business in the Czech Republic. Furthermore, it explains the recommended structure of a business plan and provides an alternative model for its development called Lean Canvas. Theoretical part of the business plan is subsequently applied in the practical part for elaboration of a business plan for the chosen field of activity. The financial plan is provided in three versions (realistic, optimistic and pessimistic), which have all been subsequently evaluated. Lean Canvas for the planned business in language tutoring has been developed at the end of the practical part. The conclusion provides summary of the findings of all business options and provides recommendations for the prospective project implementation.

Multicultural Education as Philosophical problem
Morvayová, Petra ; Pelcová, Naděžda (advisor) ; Horák, Josef (referee) ; Bendl, Stanislav (referee)
The thesis deals with multicultural education definition and practice antinomies and with paradoxes arising from its bases that are destabilizing its concept and disputing its potential to fulfil the aims that are proposed by. Our analysis insists on findings and approaches coming from philosophical, philosophical antropology perspectives, from philosophy of social science, sociology of knowledge, theories issue from social and cultural antropology, political philosophy and post-structuralist philosophy of language that takes language as an instrument or image of understanding and word sense as an intertextual. The aim of this text is to introspect terms, definitions, constructs and optics of multicultural education concepts from the point of view of critical philosophy of education.

Bernstein´s theory on language deficit and it´s significance in pedagogy
BLÁHOVÁ, Klára
The thesis presents the Bernstein's Deficit Theory of Language. In the first part, it deals with the introduction of the social determinants of the education by defining so-called linguistic codes. The following chapters address the question on how the present findings affect the process of education and the question of making the school education available to lower social strata. The last chapter presents the critique of this theory including its validation in the Czech Republic.

Language Education at Higher Education Institutions in the Process of Internationalisation
Vlčková, Iena ; Vašutová, Jaroslava (advisor) ; Váňová, Miroslava (referee) ; Andrášová, Hana (referee)
The aim of the thesis is to compare the state of reforms of the Bologna process in the Czech Republic and in Germany, and their applications in the study plans in the specialised language education in both countries. The research theme is addressed in a correlation with the situation at higher education institutions in Germany. It is so also due to the fact that at the beginning of the reforms, the German tertiary education institutions faced the same changes as the Czech ones tackle now. The first part of the thesis focuses on the general analysis of the state of the reforms in the Czech Republic and in Germany; in the second part attention is given to the state of teaching of the specialised language at higher education institutions of a non-philological orientation.

Use of software of third parties in commercial applications
Panáček, Jan ; Holcová, Irena (advisor) ; Křesťanová, Veronika (referee)
Užití software třetích stran v komerčních aplikacích 99 English summary and keywords. Usage of third party software in commercial applications. This thesis deals with the legal implications of using software written by other parties (hereafter referred to as "third party software" in conformance with industrial practice) in the process of developing a commercial application. Software developers worldwide have always been looking for a way to minimalize their costs and efforts by reusing already available software components in their own new programs and thus not investing into reinventing the wheel. This process is mainly done by incorporating open source or public domain software. It is readily available through the Internet download under seemingly non-restrictive licenses. Other options are also possible, like adopting industrial standards or settling for commercial licensing of relevant technology from other developers. The goal of this thesis is to analyze this usage of third party software. From the legal point of view, main focus is on open source licensing, international copyright law and conformance of the Czech legal system with US, European and international licensing requirements. It also deals with other issues which arise from internet distribution of works, software development and patent...

Statistical analysis of ROC curves
Kutálek, David ; Bednář, Josef (referee) ; Michálek, Jaroslav (advisor)
The ROC (Receiver Operating Characteristic) curve is a projection of two different cumulative distribution functions F0 and F1. On axis are values 1-F0(c) and 1-F1(c). The c-parameter is a real number. This curve is useful to check quality of discriminant rule which classify an object to one of two classes. The criterion is a size of an area under the curve. To solve real problems we use point and interval estimation of ROC curves and statistical hypothesis tests about ROC curves.

Early Baroque Altars in Prague
Kolář, Jan ; Zlatohlávek, Martin (advisor) ; Horyna, Mojmír (referee)
ENGLISH ANNOTATION This paper discusses Prague altars that were crafted in the years of early-baroque between 1620 and 1680. It contains a brief outline of the historical period during which - in relation to counter-reformation and recatholization after the defeat of the Estate uprising in 1620 - baroque style had been fully accepted in Czech lands. The church, supported by the state, had made it its goal to restore catholicism in Czech lands and for this purpose it also used the means of arts. The baroque church combined all kinds of arts in its complexity. The main attention of its builders was paid to altar constructions, most often wooden ones. This paper then analyzes the history and typology of the altar and its components - the altar table, the retabulum (altar leg) and the tabernacle (sanctuary). The overall development of early-baroque altars dated from late-renaissaince mannerism to the beginning of top-baroque is discussed, together with the metamorphosis of the altars' architectural concepts, the artistic perfection of the altars and of their decorative elements. Both preserved and some non-preserved altar constructions located in Prague (in the area of Hradčany, Lesser Town, Old Town and New Town) are listed and described in this paper. Furthermore, an account is given of the artists...
