The Founders of Post-Keynesianism and the Concept of Reswitching
Kraffer, Robin ; Potužák, Pavel (advisor) ; Chytilová, Helena (referee)
The thesis deals with the evolution of thoughts of Joan Robinson's, Nicholas Kaldor's, Piero Sraffa's and Luigi Pasinetti's with regards to the issue of reswitching. Discussing Robinson, Kaldor, and Sraffa, it addresses the importance of the discussion on imperfect competition and Keynes's theory for developing their opinions within the capital theory. This issue was challenged in the 50s by Robinson who asked how capital can be measured. She discovered an option of reswitching to a more capital-using technique during a wage increase, but she did not focus on it very much. The thesis also seeks the importance of Sraffa's solution to the invariant standard of value for developing the debate on reswitching the technologies in the 60s, which was joined by both Pasinetti and Robinson. However, Robinson refused again in the 70s to deem the reswitching important within the critique of the neoclassical theory, and thus joined Kaldor who had voiced similar thoughts. At the end of the thesis, the question of Robinson underestimating the importance of reswitching, as pronounced by Pasinetti, is answered - she underestimated it in the 50s, whereas it is impossible to give a clear answer when it comes to the 70s, despite the differences found among Post-Keynesians and Neo-Ricardians.

Changes to rights to claim foster care benefits since year 2013
ZEMANOVÁ, Hana
Foster care is a form of social care in the Czech Republic. A fostered children and foster parents receive from state a foster care benefits. Up until 2012 these benefits were set by Act No. 117/1995 Coll., on State Social Support. In 2012, Amendment No. 401/2012 Coll., transferred foster care benefits to Act No. 359/1999 Coll., for Social-Legal Protection of Children. With this change in law, there was also a change in the conditions of entitlement to claim foster care benefits and the establishment of efforts to professionalize foster care. The aim of my work is to analyse and compare the legislation of changes to foster care benefits from the perspective of the State Social Support Law and the Law of Social-Legal Protection of Children. I have tried to confirm or invalidate the hypotheses using quantitative research, this forms the empirical part of my work. Hypotheses were focusing on comparing the situation before and after the changes of Law for Social-Legal Protection of Children. As a technique I chose to study documents and using these documents I have provided secondary analysis. I have worked with the statistics of the Ministry for Labour and Social Affairs of the Czech Republic, the Labor Offices and the Regional Offices. The results of my findings have shown that more foster parents should be able to claim foster care benefits. Passing the bill on professional foster care has increased the interest in providing foster care, this must be seen as positive outcome. My research could be used as study material for other students of social science or for people who work in the area of social-legal protection of children. It could also be used as feedback for ministerial officials to sea the real situation since the changes in foster care law.

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.

Freezing technology of bull sperm in relation to its survivability and fertilization ability
Doležalová, Martina ; Stádník, Luděk (advisor) ; Jiří, Jiří (referee)
The aim of optimalization the insemination doses production is to provide the highest fertilization ability of spermatozoa during the demanding proces of processing fresh semen and its subsequent cryopreservation. Temperature changes causes spermatozoa damage during the cooling and freezing. Spermatozoa is exposed to cold shock and many others limiting factors, which leads to cell death and therefore to decline of fertilization ability of thawed insemination doses. For increasing spermatozoa resistance, exactly the plasma membrane resistance against cold shock was fraction of egg yolk LDL cholesterol (low density lipoprotein) at various concentrations into the comercially produced diluents added. It is believed that LDL acts possitively to plasma membrane and helps to maintain the fertilization ability of spermatozoa after thawing. Following step in the proces of insemination doses production is slow cooling of diluted semen and equilibration, when the straws are store at cooling box for 30 minutes to 240 hours. This period is necessary to penetrate of certain diluent components into the spermatazoa also maintain the balance between their intracellular and extracellular concentration. Also important is subsequent freezing temperature gradient of insemination doses. The most suitable freezing method is based on computer controlled temperature decline in freezing chamber which allows the precise control of ice crystals formation that could tear and kill the cell.
During 2012 to 2016 was repeatedly collected semen from the group of breeding bulls (n = 27, Holstein and Czech Fleckvieh breed) at AI centre. Semen which fulfill the standard entrance conditions in first step was evenly into several parts divided. For dilution the three types of comercially diluents AndroMed, Bioxcell and Triladyl with and without LDL addition were used. Into the diluents AndroMed and Bioxcell the concentration of LDL 4 %, 6 % and 8% into the dilent Triladyl 6 %, 8 % and 10 % was added. Diluted semen was filled into the glass capillares with volume 0,1 ml and temperature +4 °C. Subsequently the sample was placed to cold bath (0°C) for 10 minutes. Then the volume of capillare with physiological solution (37 °C) was mixed and for next 120 minutes was incubate. The effect of cold shock to proportion of live spermatozoa was evaluated by using Eosin and Nigrosine staining technique during heat test of spermatozoa survivability after spermatozoa heating and after 120 minutes of incubation.
The more suitable semen diluents which provide the higher spermatozoa resistance against cold shock were AndroMed and Bioxcell. Together the possitive effect of LDL addition into the diluents to lower decrease of proportion of live spermatozoa during heat test was found (P<0.05). The most suitable LDL concentration which had a favorable influence at spermatozoa resistance against cold shock was 6 % in diluent Bioxcell. Values of the proportion of live sperm were higher at the beginning of the heat test (+1.31% to + 3.2%) and after 120 minute incubation (+5.82% to +8.41%) compared to other diluents with and without addition of LDL.
In the next step the process of equilibration was optimized, is an important part of insemination doses production. The effect of the length of equilibration for subsequent fertilization ability of spermatozoa was evaluated using spermatozoa motility based of CASA and proportion of live spermatozoa after thawing and during heat survival test lasting 120 minutes (37 ° C). Suitable semen was diluted by comercially used diluent AndroMed based on soya lecithin, filled into the straws (0.25 ml), cooled and equilibrated in cooling box for 30, 120 and 240 minutes and freezed in programmable freezing box applying four types of freezing curves differing in temperature rate decline. There was used standard and by producer recommended 3. phase freezing curve, then 2. phase freezing curve, and 3. phase freezing curve with slower as well as rapid decline of temperature rate in freezing chamber, compared with standard freezing curve. The highest spermatozoa motility was found using 240 minutes of equilibration by +2.72% and +4.58% compared to other lengths of equilibration (P <0.05 to 0.01). The highest proportion of live spermatozoa was found using 120 minutes of equilibration (+6.87 % and +8.68 %). The highest average spermatozoa motility during heat test after thawing was achieved by using 2. phase freezing curve (from +2.97% to +10.37%, P <0.05), also in the proportion of live spermatozoa (from + 4.37% to +8.82%, P <0.01). When evaluating interaction between the length of equilibration and freezing curve (standard 3. phase and 2 . phase freezing curve), the highest average spermatozoa motility and proportion of live spermatozoa using 240 minutes of equilibration by both freezing curves was reached, there was no statistically significant differences. As well as, in all evaluated parts of this study the individual differences between ejaculate of bulls and within semen from one bull (P <0.05) as secondary effect were found.
To maintain good fertilization ability of semen during cryopreservation is necessary to increase the spermatozoa resistance against cold shock using addition of correct concentration of LDL into the commercially used diluents AndroMed and Bioxcell. Subsequently the fertilization ability of insemination dose is influenced by cooling, the length of equilibration and freezing. The length of equilibration 120 minutes and more as well as gentle way of freezing according to freezing curve, which ensures a gradual decrease of temperature in freezing chamber provided the higher average spermatozoa motility and proportion of live spermatozoa.

Automata in Infinite-state Formal Verification
Lengál, Ondřej ; Jančar, Petr (referee) ; Veith, Helmut (referee) ; Esparza, Javier (referee) ; Vojnar, Tomáš (advisor)
Tato práce se zaměřuje na konečné automaty nad konečnými slovy a konečnými stromy, a použití těchto automatů při formální verifikaci nekonečně stavových systémů. Práce se nejdříve věnuje rozšíření existujícího přístupu pro verifikaci programů které manipulují s haldou (konkrétně programů s dynamickými datovými strukturami), jenž je založen na stromových automatech. V práci je navrženo několik rozšíření tohoto přístupu, jako například jeho plná automatizace či jeho rozšíření o podporu uspořádaných dat. V práci jsou popsány nové rozhodovací procedury pro dvě logiky, které jsou často používány ve formální verifikaci: pro separační logiku a pro slabou monadickou druhořádovou logiku s následníkem. Obě tyto rozhodovací procedury jsou založeny na převodu jejich problému do automatové domény a následné manipulaci v této cílové doméně. Posledním přínosem této práce je vývoj nových algoritmů k efektivní manipulaci se stromovými automaty, s důrazem na testování inkluze jazyků těchto automatů a manipulaci s automaty s velkými abecedami, a implementace těchto algoritmů v knihovně pro obecné použití. Tyto vyvinuté algoritmy jsou použity jako klíčová technologie, která umožňuje použití výše uvedených technik v praxi.
