This thesis analyzes the impact of selected macroeconomic and firm-specific factors on stock prices of insurance companies. The first part describes four financial theories used to explain the share price development with a focus on fundamental analysis. The aim of the next part is empirical verification of the strong relationship between selected variables in the period from 01/2003 to 01/2013. In case of its existence, the econometric models using correlation and regression analysis are built. Considering the chosen period of time the impact of the financial crisis on potencial changes of direction and intensity of this relationship can be seen. The analysis uses real-world data from MetLife. The last chapter also describes its characteristics and compares them with the industry.

Inovace klasifikace a zkoušení podložních zemin pro realizaci lesních odvozních cest
Tvrdý, Daniel
Basic presumption of good functionality of forest roads is not only high quality of laminars in flexible pavement, but also right distribution of elasticity modules in soil plain and it's protection against degradation during the process of building. Materials used for TA ČR project, which were isolated from forest roads subsoil, were analyzed in soil mechanics laboratory of Geostar s.r.o. company for the purposes of diploma thesis. Basic laboratory tests were carried out in order to classify soils. Sub-component is to propose a simplified classification of soils for the implementation of forest haul routes. In this work are validated according to the static load tests ( SZZ ) and dynamic light boards ( LDD ) . The thesis includes evaluation of the quality of existing forest roads for faults and failure on forest roads classes 1L and 2L with different surfaces and ground covers .

Psychological aspects of gambling and realted consequenses
HŮDOVÁ, Veronika
Psychological aspects of gambling and the consequences associated with this problem My thesis deals with psychological aspects of gambling and the consequences associated with this problem. The research was focused on regular casino visitors, but partly also to gamblers who have already decided to treat their addiction. The theoretical part is divided into 8 subchapters, in which basic terms concerning gambling are mentioned, for example: definitions and categorization of the terms gambling and pathological gambling, a list of possible causes of the addiction origination, characteristics of risk groups, individual forms of gambling, the development of addiction, the addiction treatment and the possibility of a social worker intervention. The purpose of my study was to identify and analyze the motives for gambling with regard to the quality of life, with a special attention to social aspects and possibilities of a social worker intervention. In relation to the objective of the thesis four hypotheses were stated, for verification of which quantitative research was used. The interviewing method by means of a structured questionnaire was selected. The analysis of the conclusions enabled to verify the defined hypothesis, which says, that playing of hazardous games has a negative effect to level of psychological mood of the human being. Another stated hypothesis supposing that gambling causes economic, social, family and work problems has not been confirmed by the research. The following hypothesis presuming that a random winning encourages the gamblers to continue playing has been confirmed by a vast majority of respondents. And the last hypothesis, in which is defined the presumption, that the level of life quality is related to grade of pathological gambling, was also confirmed. The results of my work may be used in education or as information for social workers. Based on the findings on the issue of pathological gambling I suggest to focus on prevention of development of this dangerous addiction.

RADIATION PATIENT LOAD IN DIGITAL AND CONVENTIONAL RADIOGRAPHY
KRAINA, Aleš
To implement a digital service essentially means transition from the established SFR technique (i.e. screen-film radiography) to predominantly CR (Computed Radiography) or DR (Direct Radiography). The stated methods of digitalization differ in their use of a range of types of diagnostic equipment and image digitalization devices. The utilization of individual methods can, however, lead to different results in the amount of skin entry radiation dose and organs absorbed dose in patients undergoing ionizing radiation examination. The objective of this thesis is to compare individual methods (i.e. SFR, CR, DR) generally used for image digitalization in respect of radiation stress for patients. Radiation stress was compared both by measuring entry radiation dose on phantoms and by clinical results acquired from a KAP meter. To validate clinical results, the three most often examinations have been chosen: skull, chest, and stomach examinations. This selection was affected by its frequency and amount of radiation stress. The measured results were then compared with available foreign literature. On the basis of the measurements acquired, it is apparent that Direct Radiography leads to radical reduction in radiation dose in patients. As regards Computed Radiography, it cannot be generally said whether it entails a lower dose in patients. The measured and consequently published figures imply that there are significant differences amongst individual manufactures of CR systems (for example Fuji, Kodak, Konica, etc.) which do or do not lead, in comparison with SFR, to a lower radiation stress. According to the measurements published in this thesis, it can be stated that the use of state-of-the art CR technology could lead to reduction as high as 50 percent of the radiation stress if compared to SFR.

Deliberate Self-harm as a Specific Form of Addictive Behavior: A Concept of Non-substance Addiction Verification
Horová Šímová, Lucie ; Vacek, Jaroslav (advisor) ; Vondráčková, Petra (referee)
Záměrné sebepoškozování představuje nutkavé jednání, které se vyskytuje zejména v období dospívání. Právě v tomto období se zvyšuje riziko experimentování a riskování v oblasti chování. Dospívající jedinec je tak vystaven mnoha rizikům a nebezpečím, kterým musí čelit a bojovat s nimi. Není-li na tyto okolnosti jedinec předem dostatečně připraven, může jim velmi snadno podlehnout. Sebepoškozování se pak pro dospívajícího často stává nástrojem na zvládání nebezpečných vlivů a nepříjemných pocitů. Přetrvávat může i několik let a sebepoškozování tak může v mnohých případech přerůst v jakousi formu "závislosti". Cílem práce je popsat fenomén záměrného sebepoškozování jako jednu ze specifických forem návykového chování, ověřit tak koncept nelátkové závislosti a poukázat na některé společné či podobné znaky se závislostmi látkovými.

Text-books and Methods for their Evaluation
Dytrychová, Jana ; Pumpr, Václav (advisor) ; Beneš, Pavel (referee)
Cílem práce je ověření metod vhodných hodnocení učebnic chemie na příkladech novějších učebnic chemie pro ZŠ a nižší ročníky gymnázií. Hodnocení se týká obtížnosti a rozsahu učiva, analýzy obrazové části učebnic a řady dalších strukturních prvků učebnic. Jedná se o metody, pomocí nichž je možné obsah daných učebnic zkoumat. Některé metody jsou exaktní, do značné míry objektivní, ale také velice časově i technicky náročné. Další metody mohou být jednodušší, ale jejich vypovídací hodnota je do značné míry subjektivní. Cílem práce je zhodnotit tyto učebnice pomocí tří metod podle jejich vhodnosti a účelnosti v závislosti na situaci. Validita a objektivita každé metody je různá. Uplatnění a význam jednotlivých metod jsou závislé na potřebě daného subjektu, který chce neboje pověřen učebnice zkoumat.

44BSTRAKT Nazev práce: Využití somatických znaků a motorických testů rychlostních a koordi- načních schopností pro yýběr vojáků do kurzů boje zblízka. Anglický název práce: The use of somatic features and motor tests of speed and coordination abilities for the selection of soldiers participating in close combat courses. Cíl práce: Cílem práce je výběr prediktorů, které jsou prezentovány motorickými testy rychlostních a koordinačních schopností a somatickými znaky, za účelem predikce úspěšnosti osvojení technik boje zblízka. Metoda.: Diplomová práce je zpracována jako empirický kvantitativní výzkum obser- vačního typu a sleduje diachronní vztahy mezi kriteriální proměnnou a spojitými nezá- visle proměnnými. Pro analýzu vztahů a závislostí mezi proměnnými byly použity me- tody popisné a inferenční statistiky. Pro získání somatometrických dat jsme použili me- todiky běžně používané v somatometrii a v somatotypologii podle Heathové a Cartera ( Štěpnička, 1967). Kriteriální proměnná byla hodnocena dle současné škály pro hodno- cení technik boje zblízka v Armádě České republiky. Pro předběžnou analýzu dat jsme použili metody mnohonásobné korelace (Hendl, 2004). K navržení množiny proměn ných jsme využili algoritmu všech možných regresí (All Possible Regression). K ověření vybrané množiny proměnných jsme využili...
