In this work, we propose a novel method for a supervised dimensionality reduc- tion, which learns weights of a neural network using an evolutionary algorithm, CMA-ES, optimising the success rate of the k-NN classifier. If no activation func- tions are used in the neural network, the algorithm essentially performs a linear transformation, which can also be used inside of the Mahalanobis distance. There- fore our method can be considered to be a metric learning algorithm. By adding activations to the neural network, the algorithm can learn non-linear transfor- mations as well. We consider reductions to low-dimensional spaces, which are useful for data visualisation, and demonstrate that the resulting projections pro- vide better performance than other dimensionality reduction techniques and also that the visualisations provide better distinctions between the classes in the data thanks to the locality of the k-NN classifier. 1

1 ABSTRACT The master thesis deals with the application of the concept of diversity management. Its objective is to determine the degree of implementation of diversity management in selected primary schools in the Central Bohemian Region. The theoretical part describes the theoretical knowledge about diversity and diversity management, their importance, classifiction of every type and description of the implementation of diversity management in organization with possible connections to the schools. The theoretical part constitutes a knowledge base for the practical part, which presents the results of a survey conducted per an online questionnaire electronic forms and personal interviews with the directresses and the directors of elementary schools. The investigation of internal documents was conducted in schools of the directresses and directors in the last stage of the research process. The results of the research and conclusions presented in the thesis show a current report on the degree of implementation of diversity management in primary schools of the Central Bohemian Region, provide the description of a current situation and conclude in recommendations, while revealing the most common weak points, obstacles and aspects discouraging from the implementation of diversity management and their availability...

Optimization is an important part of mathematics and is mostly used for practical applications. For specific types of objective functions, a lot of different methods exist. A method to use when the objective is unknown and/or expensive can be difficult to determine. One of the answers is bayesian optimization, which instead of direct optimization creates a probabilistic model and uses it to constructs easily optimizable auxiliary function. It is an iterative method that uses information from previous iterations to find new point in which the objective is evaluated and tries to find the optimum within a fewer iterations. This thesis introduces bayesian optimization, suma- rizes its different approaches in lower and higher dimensions and shows when to use it suitably. An important part of the thesis is my own optimization algorithm which is applied to different practical problems - e.g. parameter optimization in machine learning algorithm. 1

The diploma thesis is focused on identification and mutual comparison of Czech-British and Slovak-British cultural standards at work environment. The main goal of the thesis is to define British cultural standards from both sides, from the Czech one and the Slovak one, and then to compare, whether the information from qualitative research corresponds with theoretical assumptions. The next goal is to find out how much different is the view on this topic from the Czech and from the Slovak perspective, if it is different. At the end of the thesis will be proposed a few suggestions, how Czech and Slovak should prepare for a longer staying in the United Kingdom in order to avoid possible cultural misunderstandings.

The purpose of this diploma thesis is to describe the features of the American culture by analyzing the cultural standards, use them for comparison with the Slovak culture and create a set of recommendations for easier adaptation of the Slovaks in the United States. The work is divided into three parts - theoretical, practical and empirical. In the theoretical section we define the concept of culture, cultural standards and cultural dimensions, and on this basis we compare the features of the American and Slovak culture. The practical part describes the characteristics of the USA - national symbols, history, geography, religion, population, economy, political system, basic features of the US market, the impact of globalization and the specifics of the US business environment. The empirical section uses a questionnaire survey to examine the American culture from the Slovak point of view. The result of this thesis is a manual created with the use of the synthesis and comparison methods.

This Diploma paper deals with topic of cultural impact on the Marketing. Connections and significance of cultural elements are explored in marketing perspective. The methodical section of this paper is focused on the Culture of New Zealand, when its specific traits are described and main cultural elements related to the marketing are analyzed. In the first part of the paper it discusses the culture in general terms as well-dynamic process and takes up with the main elements of culture. Extraordinary attention is paid to the specific symbolic perception of colours in various cultures as the most important visual factor, which is also connected with the marketing. Theoretical section of this paper is closed up by analysis of the Model cultural dimensions, which was invented by Dutch anthropologist Geert Hofstede. This model provides measurable data about main cultural traits and differences in certain cultures over the World. The Analysis of Hofstede`s model also includes relation to the various religions. The second part of the paper deals with the process of significant culture elements application on the marketing field. Primarily attention goes to the marketing mix and its tools -- product, price, place and promotion. This section defines and explains main aspects and perspectives of multicultural marketing, which are necessary to respect. The final methodical part of this paper focuses on the Culture of New Zealand and its fundamental elements related to the marketing as well. It provides overview of the main culture traits, which are essential to be adapted to launch New Zealand market successfully. Research of the visual symbol perception in Czech and New Zealand culture completes this topic. This was done through questionnaire using cultural based print advertisements. In conclusion it presents summary of the main goals found in this diploma paper.

The modern world is more and more dependent on information. As grows its importance, so does its quantity. That is why the good communication, especially the visual one, is indispensable for the proper disclosure and addressing of potential recipients of information. Graphic design provides the form of visual communication. The interconnection of different cultures is linked with the quick pace of globalization - thus the communication with different cultures is important. Each culture is based on specific values that can vary and very often do to a great extent. These values are then reflected in all areas of human activity, graphic design included. At first, we define the term culture and have a look at the process by which we acquire it - to find out its influence on us. We use as a means the interdisciplinary approach which draws knowledge on cognitive science, neuroscience, psychology and anthropology. Next, we focus on the principles of visual perception and studies concerning the difference in behavior and visual perception in different cultures. We divide the world on the basis of culture-shape events into different cultural units and we analyze graphic design in different cultures by using the knowledge from the previous chapters. We point out the principles and potential pitfalls of symbols and colors in the communication with other cultures. We describe the way how the paradigm of cultural values is reflected in the graphic design and we try to capture the features of visual communication typical for each culture.

The subject of this thesis is a pilot project of the implementation of the BI (Business Intelligence) solution in the company Haguess, a. s. The project is concerned with the analyses of data stored in a database -- DataBase Management System (DBMS) -- which is used as a data source by the web application Customer Support Center (CSC). Haguess primarily uses CSC as a helpdesk for its clients and partners, but also uses it for internal purposes. The main use of the CSC application is to support information systems delivered by Haguess. There were two motives for the choice of this subject: BI software tools had not previously been used by Haguess, and the company management was keen to get data analyses from the CSC application. That's why I decided to do these analyses. My goal was to create a practically useful solution which would be an incentive for Haguess to use BI software tools for other purposes. This thesis has two main goals. The first one is the realisation of the pilot BI solution, which would outline the possibilities for analysis of data from the CSC application using BI software tools. This involved the following activities: multidimensional analysis and BI solution design -- i.e. design of data pipelines, OLAP (On-Line Analytical Processing) cube/cubes, and user tools in MS Excel calculator. The second goal was to select the proper software tools for a future complex realisation and running of the BI solution. The first objective was achieved by doing the following: proper analysis of the CSC application data model, definition of user requests for output analysis and its comparison with the data model analysis. Based on this comparison, the basic subjects of output analyses were determined. These basic subjects were the starting point for the implementation of the BI solution. The second objective was achieved as follows: on the basis of the implementation results, basic demands (criteria) for BI software tools features were determined, bearing in mind the possible future complex realisation and running of a BI solution. Research determined which BI software tools were available on the market. The most suitable BI software tool was selected following a comparison of available options, and the criteria mentioned above. The primary outcome of this thesis is the creation of a practically usable BI solution.

The objective of the thesis is an impartial definition of elements that make up the image and identity of the Telefónica Czech Republic, a.s. company.

This master thesis aims to compare consumer behavior of generation Y (people born in the period 1982-2002) in the Czech Republic and Hong Kong, based on questionnaire data. Special attention is paid to corporate social responsibility and protection of the environment, which begin to play an important role in consumer behavior. The differences between nations are examined through the questionnaire survey, which was filled out by 155 respondents. For a deeper understanding and identification of individual motifs, consumers were conducted semi-structured interviews that focused on environmental problems and corporate social responsibility. Hong Kong and the Czech Republic have different level of individualism and uncertainty avoidance, except these two cultural dissimilarities, there were no significant differences between these two nations. Environmental protection plays a larger role in the consumer behavior of Generation Y than corporate social responsibility for both nations. Corporate social responsibility is more important for young women than for young men.
