Analyzing the link between Environmental, Social and Governance (ESG) and sovereign bond spreads: an empirical analysis of CEE countries
Guan, Yanqi ; Baxa, Jaromír (advisor) ; Merrino, Serena (referee) ; Jeřábek, Petr (referee)
This study investigates the effects of a country's environmental, social and governance (ESG) performance on sovereign bond spreads in CEE countries. We used both the sovereign bond spreads vis-à-vis the U.S. and bond spreads vis-à-vis Germany. We employed a dynamic panel generalized method of moments model, based on a sample of 10 CEE countries from 2009 to 2018. The analysis reveals that overall, better ESG performance is associated with lower sovereign bond spreads. When looking at bond spreads vis-à-vis the U.S., all three sub-dimensions of ESG are found to have significant negative impacts on sovereign bond spreads. When using bond spreads vis-à-vis Germany, only environmental and governance sides show significant effects. In addition, the results suggest that environmental side has more pronounced economic impacts on sovereign bond spreads than the other two sides in CEE countries.

Optimization of a loop-mediated isothermal amplification method for testing Streptococcus pneumoniae infection
Friček, Matúš ; Jeřábek, Petr (advisor) ; Dračínská, Helena (referee)
Streptococcus pneumoniae is grampositive pathogen bacteria. According to World Health Organisation, diseases like pnemoniae or meningitidis are most commonly caused by S. pneumoniae infection. Gold standard for pathogen detection is currently polymerase chain reaction based on specific DNA amplification. During the last decades, many DNA amplification methods have been developed. One of them is loop mediated isothermal amplification (LAMP). Thanks to low instrumental requirements and simple interpretation, this method should be appropriate alternative for pathogen detection. Putting LAMP into clinical practise is complicated mainly because of common false positive results occurance in non DNA containing samples. Based on that, one of the aims of the thesis was to identificate and eliminate main sources of DNA contamination. According to the results, the main source of contamination seems to be the products from previous reactions. Nowdays, lytA and piaB genes are the most commonly used as targets for PCR detecion of S. pneumoniae. In available publications, there is not any mention about targetting LAMP method at piaB gene for detection of S. pneumoniae. That is why the aim of this bachelor thesis was to design optimal LAMP "primers" set for piaB gene detection. Within the optimization of the...

Analysis of the Pattern of US FDI Inflow into CEE region and a Study of the Impact of US FDI on the Private Consumption Expenditure of Czech Republic
John, Erin ; Jeřábek, Petr (advisor) ; Svoboda, Karel (referee) ; Figueira, Filipa (referee)
The study presented has a dual objective. The first one being to analyse the pattern of inflow of FDI from The United States into the CEE region for a period of thirty years (1990 - 2020). The countries from the CEE region that is studied here are Bulgaria, Czech Republic, Estonia, Hungary, Latvia, Lithuania, Poland , Romania, Slovenia and Slovakia. The second objective of the study is to understand the impact US FDI inflow has on the Private Consumption Expenditure of Czech Republic for the same time period. I gathered data on twelve macroeconomic variables of the CEE region in the past thirty years. In order to study the pattern of the FDI inflow, the factors that attracted the huge amount of FDI has been taken as the primary material. Analysis has been conducted individually on each factor that possibly is an FDI attractor. The first objective is concluded with a Panel Data regression analysis of all the factors that influenced the FDI inflow from US to the CEE region over the past thirty years. The results of the analysis reveal that in the case of the US FDI inflow to the CEE region , it can be mirrored in the Universal Model of Factors Determining FDI. In order to fulfil the second objective, a Time-series regression analysis is conducted between the Private Consumption Expenditure and the...

Position of Saxonian granulite within the frame of European Variscides
Ramešová, Olga ; Jeřábek, Petr (advisor) ; Racek, Martin (referee)
The Saxonian Granulite Massif (the type granulite locality) is situated in the northwestern part of Bohemian Massif. It is an antiform with dome structure, which came to the surface from below SaxoThuringian Paleozoic units. It consits of high-pressure "Granulite core" with felsic and mafic granulites, which are surrounded by tectonic cover called "Schist mantle" of low-grade upper- crustal rocks. Massif is penetrated by several granite bodies. The Core and Mantle are separated by shear zone with a thickness of about 2 km. Geochronological dating of complex exhumation gives ages of about 340 Ma. The whole complex is affected by system of foliation and lineations. Massif was deeply buried, extremely heated and then exhumed with high exhumation rates during post collision extensional phase of the Variscan Orogeny.

Characteristics of polyphase deformation in quartz microstructure: an example from the Krkonoše-jizera Unit
Očenášková, Eva ; Jeřábek, Petr (advisor) ; Závada, Prokop (referee)
Quartzite samples taken in the east part of Krkonoše-Jizera Massif belong to metasedimentary cover of paraautochtonous unit. Rocks underwent a polyphase deformation which established a strong shape preffered orientation (SPO) of quartz grains. In folded quartz veins, deformation overprint mechanisms and microstructure, CPO and SPO relations were studied. For determination of crystal preffered orientations (CPO) the method of computer integrated polarization microscopy (CIP) was used. Microstructural analysis was focused on grain sizes, aspect ratios, long axis orientations and their relation to the deformation overprint grade. Results implies that dominant mechanism of quartz grain recrystallization is grain boundary migration. Folds were created by simple shear in microscale. The deformation overprint grade is strongest in the top of the fold hinge, where grains achieve highest aspect ratios and sizes. In the lower parts of the fold hinge the original CPO is preserved in small grains and SPO has similar orientation to original CPO. During folding CPO and SPO rotated with shear direction in dependance on deformation overprint grade.

Kinematic record of Jurassic obduction of oceanic crust in the West Carpathians
Čermák, Vojtěch ; Jeřábek, Petr (advisor) ; Vojtko, Rastislav (referee)
English abstract The bachelor thesis is focussed on problems of Jurassic subduction of Meliatic ocean in the region of the Western Carpathians. This oceanic domain opened during the Middle Triasic and closed at the end of Middle Jurassic. The existence of the oceanic domain in the Western Carpathians is documented by sedimentary rocks of oceanic origin glaucophane bearing basalts and serpentinized ultramafic rocks preserved in the area of the presumed suture zone. The chemical composition of metabasalts corresponds to the transition between the basalts of mid-oceanic ridges and basalts of island arcs. The metabasalts underwent high-pressure, low- temperature metamorphism, which proves their drag into to substantial depths during subduction and were later exhumed to structurally lower parts of the accretionary wedge. The research was focussed on identification of deformation record in units of the southern Gemeric Superunit, Meliata Unit (Borka Nappe) and Silicic Nappe. Four deformation events D1 - D4 were identified on the basis of structural analysis in the studied area. Deformation events D1 - D3 show distinct record in different units and are associated with roughly east- west direct of compression connected with the subduction of Meliatic oceanic plate, exhumation of its parts into an accretion complex...

Localization of deformation in rocks with existing anisotropy: consequences for geodynamic interpretations
Bukovská, Zita ; Jeřábek, Petr (advisor) ; Stünitz, Holger (referee) ; Grasemann, Bernhard (referee)
Localization of deformation occurs in Earth's crust as a consequence of applied stress and is widespread phenomenon that can be found in crustal rocks. Such localization of deformation can be mostly seen in a form of shear zones. Small shear zones referred as shear bands or S-C structures are often used as kinematic indicators. However, the evolution and kinematic continuity of such structures is not well identified, which makes it problematic when interpreting regional geodynamic evolution. Two possible cases were distinguished and described in this thesis: a) kinematically discontinuous S-C structures formed during two deformation events and b) kinematically continuous S-C structures formed during single deformation event. Kinematically unrelated S-C structures were studied in westernmost part of Tauern Window in Eastern Alps and in Gemer-Vepor Contact Zone in Central West Carpathians where previous geodynamic interpretations might have misinterpreted localization structures. Kinematically continuous shear bands were studied in South Armorican Shear Zone where the S-C fabrics were originally defined and described (Berthé et al., 1979). Two fabrics that crosscut each other at small angles forming S-C geometries were documented during field work and studied from macroscale down to microscale or...

The Trade Effects of the EU-Turkey Customs Union: Based on Gravity Model.
Kong, Xiangyi ; Jeřábek, Petr (advisor) ; Chondrogiannis, Ilias (referee) ; Semerák, Vilém (referee)
In view of the postponement of negotiations for the modernization of the EU-Turkey customs union, this paper is aimed to look back and examine the ex-post impacts of the CU by examining its trade creation and diversion effects. The study tests effects of 44 countries (including Turkey, 28 EU and 15 non-EU countries) with aggregated data for time period from 1989 to 2019 and disaggregated sectoral trade data from 1995 to 2019. For estimation, the gravity model with strong theoretical and empirical foundation is used by combining various fixed effects with PPML method. The results from the aggregated analysis confirm the trade-promoting effects of the EU-Turkey customs union with mixed effects on both trade within the members (intra-trade creation effects) and trade with non- members (extra-trade creation effects). But the trade diversion is not significantly proved in the model. Besides, a substantial heterogeneity in the CU effect is found across different industries, suggesting the CU has significantly improved the trade on textiles, transportation, machinery, metals and plastics/rubbers, but negligibly influence agriculture, mineral and chemicals. Furthermore, the study also evidences that the impact of the CU is stronger in EU's export to Turkey than Turkey's export to the EU. Finally, CU's...
