Optimization in engineering design problems
Sýkora, Zdeněk ; Cabalka, Matouš (referee) ; Mrázková, Eva (advisor)
This bachelor thesis deals with the use of optimization in the problems of beam loading and buckling stability. The problems were solved in the GAMS software. The solutions of the first two problems is compared with results obtained using software Ansys. It also contains chapters on basic optimization theory, the theory of ordinary differential equations and a chapter on selected concepts in mechanics of materials.

Hormones and Competitive Behavior
Sýkora, Zdeněk ; Cingl, Lubomír (advisor) ; Bauer, Michal (referee)
The thesis aims to contribute to the literature on the biological underpinnings of important economic behaviors. Financial markets can become dangerously unstable from many reasons such as the hormones contained in our bodies. We primarily focus on the effect of basal testosterone and cortisol on willingness to compete and risk taking. We also investigate their interaction called the dual-hormone hypothesis, because it has not been sufficiently analyzed and replicated so far. We run a controlled laboratory experiment with 96 university students and have gender-balanced dataset, thus we can also examine gender differences. We find no support that higher testosterone increase willingness to compete in men as opposed to most of the recent literature. Moreover, higher levels of testosterone decrease competitiveness but only for women. We further find positive effect of the 2D:4D ratio for women and negative effect of trait anxiety for men on competitiveness. There are also substantial gender differences in competitive and risk taking behavior. We cannot confirm the dual-hormone hypothesis for willingness to compete. But we find significant support for the dual-hormone hypothesis for risk taking for women and with negative effect of testosterone on risk taking. The effects stay robust even after...

On the Nature of Gender Differences in Attitudes to Risk
Sýkora, Zdeněk ; Cingl, Lubomír (advisor) ; Troch, Tomáš (referee)
Despite a number of studies demonstrating that women are more risk averse than men, this strong consensus has recently been questioned. In this thesis we discuss what may be the reason for such contradicting outcomes. Firstly, we describe the most common elicitation methods and compare them from the perspective of reporting gender differences in risk attitudes. We also summarize current literature in the topic. Then we describe a design and analyze original dataset from a survey experiment conducted with university students, mainly investigating responses to a general risk question. We examine the role of variables that are different between genders and can explain risk preferences to see whether the gender difference is robust. We further focus on different dimensions of risk: we ask about risk taking in driving, financial, sports, career, and health domains. Our findings show that the gender differences in risk preferences are significant, ubiquitous, and can be detected by a simple survey measure, even after controlling for additional characteristics that are known to play role in attitudes to risk and differ between men and women. This applies for all studied domains except for the health one.
