The Internet and copyright-modes of the use and the scope of protection of a work (traditional usage, peer to peer network, email...)
Nebesář, Marek ; Holcová, Irena (advisor) ; Křesťanová, Veronika (referee)
80 Abstract The aim of this thesis is to describe various ways of use of works on the Internet and method of their copyright protection in this specific environment. Because without any doubt the Internet interferes with everyday life of today's society and subsequently has a significant effect on further development of a legal system, this topic becomes very relevant. The thesis itself is divided into four chapters. The first chapter is devoted to general description of the Internet and copyright law, and contains explanation of development of this private law area in the territory of the independent Czech Republic, including list of national and international legal sources. The second chapter defines the copyrighted work and its different types according to the Czech Copyright Act, an individual author, use of the work, whether in the form of a contractual or non-contractual disclosure and also important topic of making the work available through the Internet. The third chapter analyzes the copyright protection in the private and public spheres, and technical means of such protection (DRM). The last, and with respect to the discussed topic the most important, fourth chapter deals with various ways of use of works on the Internet, including their detailed description. Downloading and uploading, legislation...

Vztah vnitřní organizace podniků v různých odvětvích a jejich výkonu
Pardupa, Martin ; Jílková, Jiřina (advisor) ; Vorlíček, Jan (referee) ; Hučka, Miroslav (referee)
This dissertation is thus aiming to create a (1) view on current and historical theoretical and practical approaches of organization economics, (2) to assess their assumptions and implications and explain their contradictions in relation to individual base of the knowledge and motivation. (4) It suggests a framework that might give an economic and theoretical rationale to various managerial measures related to the true ("effective") effort of an individual in a firm that is (5) finally tested in empirical research. For the reasons mentioned above, the overview of often divergent methodological approaches is of a key importance, therefore much attention is dedicated to their description and analysis in the first part of the thesis. It is followed by the introduction of a new framework used in the analysis of various managerial measures applied in the firm, and finally, the hypotheses which test certain assumptions of the framework on empirical data. The "effective effort, cooperation and rivalry framework" is the main output of this thesis, as it explains the roots and influence of direct and indirect managerial measures through the behavior of workers (rivalry, cooperation, rent-seeking) on company's performance. The framework combines three existing independent approaches analyzing the link between managerial measures and company's performance without denying any of the predecessors, and it also brings a new interpretation of the functions of managerial decisions in the firm and the link on material resources. The framework attempts to answer the following research question: Which factors and in a what way influence the effective effort of an individual in the firm? Can this approach be formalized and tested on empirical data? Answering this question would be beneficial for both managers and academia as it would facilitate them to undertake that managerial measures, that would lead to an improvement of firm's long term performance and avoid those actions, which would work contradictory. The empirical analysis focuses on efficiency of several types of incentives and trainings in the medium-sized company on the lowest level of hierarchy (furthermore there is the lack of similar analyses dedicated to an enterprise in Central and Eastern Europe or in such chronological extent in a single firm anywhere in Europe). The extensive data is provided by a leading Czech (mostly retail) betting company operating in a legislatively stable environment not exposed to the currency fluctuations and economic cycle with oligopolistic characteristics. Other industries (besides retail) would hardly provide such high quality data for such a long period suitable for the chosen analysis of the revenues' influence of various managerial measures (training of sale staff, introduction of an upside component of wage, nonmonetary rewards) applied to workers. The results of the empirical analysis show the possible positive effect of increased wage variability on the employee's performance, although the effect of training and nonmonetary rewards was proven as insignificant. These results (positive/negative effect or significance/insignificance) for a low skilled workforce being able to effectively affect the quality of the output (as is the Fortuna case) are in line with the Effective effort, cooperation and rivalry framework.

Crossplatform user interface API for C/C++
Meluzín, Vojtěch ; Dokulil, Jiří (referee) ; Zavoral, Filip (advisor)
The goal of MWindows project is creation of a crossplatform graphical user interface toolkit for C++ language, hence it is designated for performance dependent applications. The toolkit has to hide target platform speci cs, provide superstandard features such as general styling on a plugin basis, automatic control placement, data sharing, language translation etc. Lowlevel characteristics have to guarantee portability even to platforms without internal window system, e.g. 3D graphical modes. Finally there is a need for general platform-independent way to build particular programs with as easy way to access application data (such as images or translation databases) as possible.

Evolutionary contraints in the origin of viviparity in Amniotes Why there are no viviparous birds?
Chmelová, Kristýna ; Kratochvíl, Lukáš (advisor) ; Gvoždík, Václav (referee)
Evolution of life-bearing have fascinated biologists for over a long time. Viviparity has evolved many times within separate vertebrate lineages and it is a geographically widespread phenomenon. The majority of these independent origins have occured within lizards and snakes. Several hypotheses have been suggested to explain the selective pressures leading to viviparity in reptiles. One of the most frequently supported hypotheses views viviparity as an adaptation to a cold climate, i.e. viviparous mothers ensure favorable thermoregulation to developing embryos. It is generally supposed that egg retention is an intermediate stage in the evolution of live-bearing. Inclination to egg retention seems to be one of the most important preadaptations of viviparity in vertebrates. Additional limiting factors are probably for instance type of eggshell, mode of sex determinantion or egg guarding as an alternative mode of parental care.

Vliv endokrinních disruptorů na funkčnost spermií a změny ve steroidogenezi transkriptomik u ryb
HATEF, Azadeh
In the present study, both in vitro and in vivo experiments were performed to investigate modes of action of selected EDCs including mercury chloride (HgCl2), bisphenol A (BPA), vinclozolin (VZ) and Di-(2-ethylhexyl)-phthalate (DEHP) on male reproductive physiology in fish. Results obtained from in vitro studies showed that EDCs decrease sperm motility via disruption in energetics and damage to spermatozoa; however the effective doses are higher than reported in the environmentally relevant concentrations. In contrast, in vivo studies showed adverse effects of BPA, VZ, and DEHP on sperm quality at environmentally relevant concentrations. Decrease in sperm quality is associated with disruption in testicular steroidogenesis, particularly inhibition of androgens. Only BPA induced vitellogenin production, associated with increase in transcripts of estrogen receptor, androgen receptor and cytochrome P450 mRNA at the high dose approaching environmental level. Inhibition of androgen production is due to disruption in transfer of cholesterol into the steroidogenesis pathway, because transcript of steroidogenic acute regulatory protein mRNA was decreased. In addition, BPA acts through sex steroid-mediated mechanism while DEHP mode of action is sex-steroid independent mechanism.

Numerical Analysis of the Thickness Influence on the Stress Field at Crack Tip for Different Poisson´s Ratios
Seitl, Stanislav ; Hanzlovský, Radovan ; Fernandez, C.
The influence of in- and out- of plane constraints on the behaviour of cracks under mode- I loading condition is studied. The independence of the stress intensity tensor structure, with respect to the specimen thickness B shows that under loss of constraint conditions higher order tensor members of the Williams expansion must be considered to characterize the singular stress field, and to explain the increasing apparent fracture toughness resulting experimentally for decreasing specimen thickness. A numerical study of the effect of Poisson’s ratio on stationary mode I crack tip fields is presented in the contribution. Finite element calculations for two-dimensional (v =0) and three-dimensional bodies are performed and compared. Further, the stress intensity tensor K, and the elastic txx and tzz components of the tij constraint tensor in the middle of a three-dimensional crack front are determined using direct methods for the same level of loading.

Study of Generation, Trapping and Atomization of Hydride Forming Elements for Atomic Spectrometry
Furdíková, Zuzana ; Sommer, Lumír (referee) ; Čelechovská, Olga (referee) ; Řehůřková, Irena (referee) ; Dočekalová, Hana (advisor)
Interference effects of co-generated hydrides of arsenic, antimony, bismuth and selenium on trapping behavior of selenium or antimony hydrides (analytes) within iridium modified, transversely heated graphite tube atomizer (THGA) was investigated. A twin-channel hydride generation system was used for independent separate generation and introduction of analyte and interferent hydrides, i.e. in simultaneous and/or sequential analyte-interferent and interferent-analyte mode of operation. Influence of the analyte and modifier mass, interferent amount, trapping temperature and composition of the gaseous phase was studied. A simple approach for elimination of mutual interference effects by modification of the gaseous phase with oxygen in substoichiometric ratio to chemically generated hydrogen is proposed and suppression of these interference effects is demonstrated. A hypothesis on mechanism of trapping and mutual interference effects is drawn.

The young poetry of the 1990s
PIORECKÝ, Karel
The submitted work is oriented towards the writing of young poets who made their authorial debuts into literary communication in the 1990s. It regards the creation of authors unburdered by experience with the cutural politics valid before November 1989, and therefore creation born in the complicated context of the post-totalitarian cultural situation in which very different traditions were combined, including traditions which were banned from public communication during the previous decades. Parallel with this process the young poetry of the 1990s was born, whose character was inevitably marked by the period interest in everything from the past that had been until recently forbidden. The work begins with an independent chapter devoted to the literary-critrical reception of young poetry in the 1990s. Aspects analyzed include the language, framework of values, criteria and expectations which were valid for contemporary literary criticism of young poetry in the 1990s. It is demonstrated that the key question for young poetry to answer was the question of what traditions it should draw upon in the changed and democratized cultural and social conditions. Expectations were oriented in the direction of the past, towards a connection with one of the worthy and newly non-proscribed traditions, rather than towards a neo-avantgarde seach for new expressive registers. The subsequent three chapters follow three expressive currents within the framework of young poetry of the 1990s {--} spiritual poetry, objective poetry and imaginative poetry. Analytical and interpretational explorations of these three currents are linked by a common point of view, which is a focus on the lyrical subject and the form of its stylization. This methodological point of departure leans on Červenka's theory of the the lyric subject, to which is devoted the independent theoretically oriented chapter in the introductory part of the work. This unified focus of attention on the lyric subject made it possible in the conclusion of this work to create a typology of the form of the lyric subject and to follow basic tendencies characteristic for subjectivity in the young poetry of the 1990s. It was demonstrated that the young poetry of the 1990s was willing to accept the three traditional lyrical modes and expressive registers, but it removes from them any kind of programmatic and ideological accents. Traditional lyrical modes, after their transplantation into a post-totalitarian and also post-modern situation, stop being part of a master narrative and therefore their original metanarrative character is eliminated (from spiritual poetry the explicit confessionality is lost, imaginative poetry removes surrealistic revolutionarity and psychologism, the poetry of objectivity eliminates the pathos regarding necessary developmental change, with it this lyrical mode was applied by Skupina 42). Traditions therefore do not continue to evolve in their original forms, but are selectively used with a view to the current state of culture and thought.

Trade-off between egg size and number at the level of bird families
Špaldoňová, Alexandra ; Hořák, David (advisor) ; Reif, Jiří (referee)
Trade-off between offspring size and number belongs to the most discussed concepts in the life history theory. The aim of this study was to elucidate the relationship between egg size, clutch size and female body mass at the family level in bird's and to examine whether there is the relationship between offspring size and number and life history traits specific for particular bird families. From published sources, I collected data about 5.073 species belong in 146 families. Most species of birds lay smaller clutches, on average three eggs. In 112 families from 130 tested eggs size was positively correlated with female body mass. There is evidence that egg size and clutch size are inversely related in 83 families from 130 tested but only for 34 families was significant. The relationship exists independently of female body mass across bird families and this suggests a trade-off between these traits. The relationship between the strength and shape of egg size-number correlations and life history characteristics of bird families was not frequent. According to results, the strength of correlation seems to be related to development mode and diet type. The negative egg size-number correlation is stronger when incubation period and fledging time is longer and in birds with longer lifespan. The...
