Stereotype threat and women's math performance in Czech schools
Rubín, Tomáš ; Smetáčková, Irena (advisor) ; Rendl, Miroslav (referee)
One of possible explanations of under-representation of women in math-related jobs is that they can be under influence of stereotype threat. This threat can operate in situations where one has to show performance and simultaneously feels the risk of being evaluated through stereotypes. This thesis explores almost 20 years history of research on this topic and explains some related processes that operate through this threat. In the study reported here we try to prove the existence of stereotype threat in Czech girl who are 14 years old. We conduct an experiment in which we test the impact of heightened salience on actual performance of math-identified girls. For the purpose of this study we translated Mathematics Identification Questionnaire into Czech language. This instrument was used in our country for the first time. Although some results indicate an influence of stereotype threat, this evidence is weak. Limits and future research challenges are discussed in the end of thesis. Powered by TCPDF (www.tcpdf.org)

Stochastic Evolution Systems and Their Applications
Rubín, Tomáš ; Maslowski, Bohdan (advisor) ; Hlubinka, Daniel (referee)
In the Thesis, linear stochastic differential equations in a Hilbert space driven by a cylindrical fractional Brownian motion with the Hurst parameter in the interval H < 1/2 are considered. Under the conditions on the range of the diffusion coefficient, existence of the mild solution is proved together with measurability and continuity. Existence of a limiting distribution is shown for exponentially stable semigroups. The theory is modified for the case of analytical semigroups. In this case, the conditions for the diffusion coefficient are weakened. The scope of the theory is illustrated on the Heath-Jarrow-Morton model, the wave equation, and the heat equation. 1

Fractional Brownian motion
Rubín, Tomáš ; Maslowski, Bohdan (advisor) ; Kříž, Pavel (referee)
Fractional Brownian motion is a nontrivial generalization of standard Brownian motion (Wie- ner process). Definition leaves independence of increments, whereas dependence is controlled by the Hurst index. This paper deals with proofs of fractional Brownian motion's properties such as correlation of increments, selfsimilarity, long-range dependence and analytical pro- perties of its paths, i.e. Hölder continuity and nondifferentiability. Furthermore, the proof of the theorem about nondifferentiability is presented in a stronger form than it is usual in published papers about fractional Brownian motion. Further topics are simulations of the process's paths, suitable even for general Gaussian processes, and point estimators of the Hurst index. 1
