Polarization of the Czech Media Landscape after 2013: Discourse Analysis of New Media ProjectsPolarization of the Czech Media Landscape after 2013: Discourse Analysis of New Media Projects
Lebedová, Veronika ; Pudlák, Štěpán (advisor) ; Řehořová, Irena (referee)
The thesis deals with the polarization of Czech media landscape after 2013 as a discursive construct. Our topic is the emergence of new media projects, responding to the takeover of MAFRA by Andrej Babis. Three of these are being discussed: Echo24.cz, Reportér and Neovlivní.cz. The thesis aims to describe the discourse of the alternative media, its own representation in current situation. The subject is based on several concepts. First of them is the theory of social responsibility, which is a strong social value despite being quite questionable. Then, we discuss the trend of media ownership concentration and the development of Czech media after 1989, which has come to important changes, such as the change of the overall model of media ownership and the polarization of the media landscape itself. The first part of the thesis serves as a contextual background for the critical discourse analysis. The analysis verifies the hypothesis as follows: Alternative media is defined in opposition to the mainstream and uses the arguments based on the principles of the social responsibility theory to represent its own position, goals and interests. As a result, we found out, that the new projects construct an opposition us versus them as independence versus oligarchization. At the same time, the principles of...

Methods for prolonging the shelf life of minced fish meat
KUBÍK, Michal
The initial part of this work sums up the methods of mechanical mincing of fish meat and food safety. The fish meat processing methods are described in detail and supplemented with the respective legislative. The primary factors affecting the quality and usability of the product are the changes caused by proteolysis and autolysis, the occurrence of microorganisms and biogenic amines. These processes are natural; they may only be delayed or reduced in intensity. Despite the possibility of using different preservatives, we need to pay attention to the basic hygienic and technological processes particularly in shortening their duration and storage conditions, especially the temperature. The major part of the research focuses on the possibility of using the enzyme preparation of SEA-i and its impact on the occurrence of biogenic amines, coliform bacteria and the total number of microorganisms in separated carp meat in smoking and liquid smoke treatment. Using SEA-i has proved to be a suitable means for preventing the development of biogenic amines. He was able to suppress the development of histamine below the detectable limit and the amount of putrescine decreased to 24 mg.kg-1 compared to the control group with the appearance of 89 mg.kg-1. For other biogenic amines has also demonstrated potent inhibitory effect. Its effect was also demonstrated in the total number of microorganisms.

The Trends of Partner Cohabitation Forms in the Context of Social Policy Development
VODRÁŽKOVÁ, Magdalena
This thesis maps trends and development of partner cohabitation in relation to social policy changes. Marriage has a rich history and its form and nature has changed several times in the past. In the last sixty years, the divorce rate has risen, women have become more emancipated and their participation in the labour market. Unmarried cohabitation is similar to marriage which it also usually precedes. This type of partner cohabitation is currently more common and it sometimes replaces marriage completely. The theoretical part of this thesis also describes the founding of a family, its function and history, because starting a family is closely related to marriage and unmarried cohabitation. The remainder of the theoretical part is dedicated to social and family policy, which is characterized in greater detail, regarding its concepts, goals and tools, together with family support systems and measures. The goal of this thesis was to map preferred forms of partner cohabitation at various stages of social policy development in the Czech Republic and to determine the influence of individual social policy measures on population development in the context of marriage, birth or divorce rates in the short and long term. Two hypotheses related to the goals of this thesis have been established. Hypothesis no. 1: The concept of marriage has been more important for women than for men at all stages of social policy development. Hypothesis no. 2: University-educated individuals prefer marriage more than those with elementary education. The first part of the research results is a comparative analysis of available secondary resources relating to certain development stages of social policy in our country. The second part of the research was conducted in the form of a pilot study, using the quantitative method on questionnaires. Results indicate that significant change in the material conditions of families with children has positive effect on population growth. Women used to link marriage to motherhood and to greater certainty while raising children. The number of marriages among university graduates is increasing. This has also been caused by the higher number of people with university education. This trend started in the early 90s. Respondents with university degrees expressed the opinion that the main reason to form a marriage is having children, yet they do not consider it as important as those without university education.

Výskyt kvasinek v silážích a jejich význam
Vaculíková, Barbora
The aim of the study was to assess the effect of yeast in silage and verify the fact that the additives will ensure inhibition of undesirable microorganisms. The literature review focused on the metabolism of yeast, their importance in silages limitations and possibilities. Model experiments were performed with peas with barley silage and with corn silage. The influence of additives on the final quality of the silage and their influence on the content of microorganisms, together with the quality of the fermentation process, was assessed. According to the provided measurements it can be argued that the use of additives was only partly due to the limitations of yeast and aerobic stability. Chemical preservatives based on organic acids favorably slowed the onset of secondary fermentation in peas with barley silage, even though there was no suppression of the number of yeast on this option. The negative correlation of yeast dry matter content was confirmed for the corn silage (r= 0.6219). In the silage with a chemical preservative (2,402 +- 0,775 log CFU/g) positive effect (P<0,05) on the limitation of yeast compared was detected to the control silage. Based on measurements of pH the degree of contamination of yeast cannot be evaluated. It was confirmed that even the best additive cannot guarantee quality and stable silage, if the principles of silage are not adhered to.

Evaluating production and quality losses from game damage in spring barley
Dvořák, J. ; Cerkal, R. ; Kamler, Jiří ; Šejnohová, H.
During a field trial in locality Žabčice in the year 2004 the effect of different damages of plants on yield and quality of the barley variety Amulet was detected by the method Latin square. Plants were damaged in three intensities (not damaged, damaged 25% and damaged 50%). From result is evident the decline of both economic production and production of front corn in the case, that was damaged 50% of the leaf area of the plants in the beginning of stem extension stage (by 6,7% or 6,6% in comparison to non damaged area), but better ratio of corn to straw was found out (0,93). The stress of the plants induced by the damage did not caused neither any significant changes in the content of selected chemical component in the corn, nor decline of the content extractive matter in the malt.

Studium obsahových látek chmele : obsah a složení silic a vybraných antioxidantů v chmelových šišticích /
Pluháčková, Helena
The aim of this work was the determination of essential oil content and composition in hop cones according to the founding year of the hop garden and for selected hop varieties (Sládek, Premiant, Saaz) in the hop-growing region Tršice; the comparison of essential oil content and composition for the most important Czech hop variety -- Saaz -- from different hop-growing regions in the Czech Republic (Saaz, Úštěk, Tršice) according to the founding year of the hop garden; and determination of the content of tocopherol isomers and the activity of vitamin E in hop cones. The hop cone samples were taken from the hop-growing region Tršice according to the variety and the founding year of the hop garden in harvest years 2009-2011 for the determination of essential oil content and composition, in harvest years 2010 and 2011 also the activity of vitamin E and its isomers was determined. For the evaluation of the environmental influence, i.e. the effect of hop-growing regions and the founding year of the hop garden to the essential oil content and composition, the samples from Úštěk and Saaz hop growing regions were obtained. The results indicate that the highest essential oil content was found in the samples of Sládek variety (1095-1946 ul.100g-1), the lowest essential oil content was determined for the Saaz variety (271-478 ul.100g-1), but with important share of the essential oil component farnesene. The variety Premiant showed the highest activity of vitamin E in the rates of 32.10 -- 120.98 mg.kg-1. The results from different hop-growing regions indicate that the hop-gardens need to be renewed steadily, because the age structure of the hop growth is one of the important factors that influence the yield stability. The age structure of hop-gardens is insufficient from the long-term point of view, especially in the Úštěk and Saaz regions, the highest essential oil content was found in the region Tršice.

The influence of slaughter weight and sex on carcass of pigs.
VONDRUŠKA, Miroslav
The aim of this thesis was to obtain information on the genotype and sex influence on carcass characteristics of pigs of the following final hybrids combinations: (CL x CLW) x CLW ? sire line, (CL x CLW) x (CLW ? sire line x Pn), (CL x CLW) x (D x Pn) and (CL x CLW) x (CLW ? sire line x D) with a balanced sex ratio (barrows: gilts). An influence of the genotype on the lean meat content has been proven, while the (CL x CLW) x (D x Pn) combination reached the highest values, with an average of 57.95 %. A statistical significance of differences was also found between the sexes, when gilts reached 58.06 % average lean meat content, compared to the barrows 54.70 % average lean meat content (3.36 % difference). The back fat thickness showed a high statistical significance in terms of genotype, the lowest back fat thickness was measured in the (CL x CLW) x (D x Pn) combination with value of 21.69 mm. Barrows reached higher values, the average height of gilts was 22.03 mm, 25.25 mm in barrows. In the loin eye area indicator, the genotype influence has not been proven. For gilts, the mean value of 5228 mm2, in barrows value of 4707 mm2. Content of main meat parts, or more precisely hams, presented statistically significant differences in terms of genotype. The (CL x CLW) x (D x Pn) combination reached the highest values, with content of 53.23 %, 21.9 % respectively. A significant statistical difference was determined also between sexes, with an average main meat parts of gilts and barrows 51.32 % and 48.45 %, respectively; in the case of ham 21.07 % and 19.98 %. The slaughter weight in relation to the lean meat content showed a very good value in the mass range less than 100 kg (57.84 %), but the muscle proportion 57.16 % has been positive even in the mass range 100 ? 109.9 kg.
