Establishing speaker's age and sex
Rendek, Tomáš ; Pfeifer, Václav (referee) ; Atassi, Hicham (advisor)
This work deals with speaker´s age and gender recognition. At the beginning it introduces the practical usage of this application and discusses the solutions available. The theoretical part of the thesis specifies the feature extraction and reduction methods and speech databases used in the experiments. The practical part describes the recognizer implemented in the Emotional tool and in two chapters describes the individual experiments. Regarding speaker´s gender estimation; we focused on the impact of the emotional state and speaker's age on the classification process. The two remain experiments were dedicated for general gender estimation performed by using two different classifiers – GMM and k-NN. These two classifiers were used in age estimation as well. In this case, four Group of age was formed and two different feature sets namely: segmental and suprasegmental were exploited four groups

Comparison of analysis of speech in dependence on age and gender
Báňa, Josef ; Smékal, Zdeněk (referee) ; Atassi, Hicham (advisor)
This thesis deals with analysis of speech signal in dependence on the gender and the age of the speaker. We tried to investigate through the features to find the best set for the automatic classification of speakers. It also contains a brief discussion about the speech signal and its characteristics. We used a program called Praat for the speech analysis purpose. This program is also described in this work. We mainly focused on the suprasegmental features of speech. Our first step was to make our own speech corpus which should contain speech records from speakers with various age and gender. We made the analysis using Praat and reported it within this thesis. For the automatic classification purpose, twelve features were selected basing on there quality criteria and used with a neural network to classify the speakers to classes with different age and gender. As it was mentioned, a neural network was used as a classifier. We used “Neural Network Toolbox” in the Matlab program to create and train our networks.

The Depiction of Gender in Terry Pratchett's Discworld
Mládek, Pavel ; Topolovská, Tereza (advisor) ; Ženíšek, Jakub (referee)
This work concerns itself with the Discworld series of the British fantasy author Terry Pratchett, and with how sex and gender are depicted in it. It mainly looks at the books Feet of Clay (1996), The Fifth Elephant (1999), Monstrous Regiment (2003), and Raising Steam (2013), which deal with these topics the most openly. It attempts to reveal whether the series presents more the view that sex and gender are tightly intertwined, or even that gender does not exist at all, so-called gender critical view, or whether gender and sex are more or less independent of each other and the characters in the series may present a gender different from the one assigned to them at birth. At the same time the work examines whether the depictions of gender evolve as the series go on or not.

Biometrie a kondice prasete divokého (Sus scrofa) s ohledem na vegetační stupňovitost
Procházková, Pavla
The content of this thesis is the evaluation of biometric data of wild boar (Sus scrofa L.) collected in 2014–2019 at sites throughout the Czech Republic. The data evaluation sought to relate the observed body parameters to forest vegetation stages. Emphasis was placed on the parameter of fat thickness as an indicator of body condition, and body parameters of weight after emergence, body length and chest height were also worked with. Differences in body parameters based on age, sex and forest vegetation stages were sought and statistical significance of these factors was tested. A weak correlation was found between some body parameters in the piglet category. Furthermore, fat thickness was found to be related to the sex of individuals older than 12 months. Fat thickness increased with age in females at all age classes while males reached their total fat height at the end of the first year of life. There was a strong correlation of body length parameter with weight and chest height of individuals.

Analýza masné užitkovosti vybraných plemen masného skotu
Ovčáček, Jindřich
The aim of the bachelor thesis was to analyse selected breeds for meat performance parameters in the Czech Republic. The analysed breeds Aberdeen angus, Hereford, Charolais and Meat Simmental were measured during the year for individual meat performance parameters such as birth weight, weight at 120 and 210 days, gain up to 120 days, gain up to 210 days, gain between 120 and 210 days, slaughter weight, average gain to age at slaughter, total gain and carcass. These results were then compared between breeds and the economics of breeding selected beef cattle breeds were also determined from these data. The result showed that breed has an effect on meat performance, with the Charolais and Meat Simmental breeds performing best and the Aberdeen Angus and Hereford breeds performing worst in the comparison between breeds. Sex within breed was also found to influence meat yield, with bulls of all breeds studied achieving higher meat yields than heifers.

Frekvence příjmu mléčné krmné směsi v průběhu dne a její vliv na růst u telat českého strakatého skotu
Vozihnojová, Dominika
In this diploma thesis analysis of frequency of milk compound intake during the day and its effect on growth in Czech fleckvieh cattle calves was performed in a large-capacity calf shed Kelčice, which belongs to the agricultural cooperative Určice. The monitoring, which lasted 12 months (from March 2022 to March 2023), included the frequency of daily milk compound intake. The calves were weighed on the day of arrival at the reception pavilion and again on the day of daparture to calf nursery at the end of the milk feeding period. During the monitoring, the temperature (°C) and relative humidity (%) in the calf house were measured using the HOBO sensor. Bulls showed greater weight gain (by 0.06 kg) compared to heifers at the same intake of milk replacer (P < 0.01). The greatest growth was recorded in calves that received an average of 7.1 and more liters of milk replacer (MR) per day (P < 0.01). The effect of the number of feeding days was also observed, when calves achieved greater average daily gain during a longer stay in the reception pavilion (P < 0.01). It was observed that temperatures above 20 °C had a negative effect on the calves, which was shown by the average daily gain, which was the smallest at the highest intake of MR. On the contrary, the temperature of 0-5 °C suited the calves the most when it showed the greatest growth.

Analysis of ponies bred for sports performance based on results in international dressage competitions
Havlíčková, Kristina
This thesis aimed to evaluate the performance of sports ponies at the international dressage level based on the following factors: sports season, age, sex and breed. The basis of the database was the dressage pony ranking of the International Equestrian Federation from 2014 to 2020. Two analyses were performed, one for the whole population and the second for the top 10% of ponies of each season. Statistically significant impact was found in the sports season (p ≤ 0.05) and high statistical significance in age and breed (p ≤ 0.01). Sex was the only factor with no statistical significance (p > 0.05). Ponies achieved the best average results in the year 2019 (983.72 points). On average, the best age categories were 9-12 (968.91 points) and 13-16 (968.90 points). Stallions were the best-performing sex (975.28 points). Ponies of Dutch Riding Horse and Pony Studbook (1 040.70 points) and Danish Sports Pony (1 039.50 points) achieved the best point results. Only the sports season and breed in the top 10% of ponies showed statistical significance (p ≤ 0.05). Ponies earned the highest number of points on average in the year 2020 (1 873.80 points). The best performance was given by ponies aged 17 and higher (1 899.00 points), although this category contained only two specimens. Stallions earned the highest number of performance points (1 842.70 points), and the best breed was the German Riding Pony (1 828.20 points).

Analýza současné situace a výkonnosti koní v soutěžích vytrvalosti v České republice a ve světě
Zelenková, Veronika
The aim of this study was to evaluate the current situation and the development of horses in endurance competitions in the Czech Republic and in the world using factors of age, sex, year of the competition and breed. The thesis was based on the databases of endurance rankings for years 2020, 2021 and 2022 published by the ČJF and FEI, which we subsequently processed statistically. A highly conclusive influence was discovered for the factors of year of the competition and age of the horses, breed factor was conclusive and sex factor was not conclusive. The best results were achieved by horses aged 15-17 years (71,68 points), the most successful are geldings (65,23 points) and the best performance is delivered by Arabian horse (73,51 %), which was also confirmed by subsequent testing using the Scheffe test. Horse performance increased slightly over the course of three years. Similar methodology was used to perform an analysis of the database of the endurance rankings by the ČJF. A highly conclusive influence was discovered only for the factor of year of the competition and factor of age was discovered conclusive, which can be attributed to the small population of endurance horses in the Czech Republic. The analysis of the endurance rankings by ČJF shows, that the best results are achieved by horses aged 9-11 years (158,57 points), the most successful are geldings (145,29 points) and the best performance is delivered by Arabian horse (171,98 points). Horse performance in Czech Republic increased conclusively over the course of three years.

Černá, Julia ; Koldinská, Kristina (advisor) ; Tomšej, Jakub (referee)
THE EMPLOYMENT OF WOMEN IN LEADERSHIP POSITIONS FROM THE LABOR LAW PERSPECTIVE ABSTRACT This thesis focuses on the issue of gender-based discrimination in the field of economic and political leadership. It explores various forms of discriminatory conduct and examines the viability of positive measures and the rationales for their adoption. Special attention is given to the examination of the institute of quotas, their impact on the current (lack of) gender equality, and the prospects of integrating them into our legal framework through labor law regulations. The thesis outlines previous attempts to introduce them, the current stance towards their implementation and some regulatory models that can be observed in foreign jurisdictions. Within a broader sociological-economic context, the thesis analyzes specific barriers that hinder women in their career advancements, such as the glass ceiling and tokenism. It analyzes the causes and consequences of labor market segmentation in terms of horizontal and vertical segregation and emphasizes the problematic nature of this phenomenon. The main objective of the thesis is to analyze current legal systems in terms of international, European Union, and Czech law in their efforts of addressing the aforementioned issue. Relevant legislation regulating this area is...
