Doble-balanced mixer - laboratory equipment
Dušek, Libor ; Baran, Ondřej (referee) ; Vágner, Petr (advisor)
The aim of this work was double-balanced mixer implementation, which will be used like laboratory equipment. This thesis deals with design of the double-balanced mixer from first theoretical principles to a practical design of a laboratory equipment. For the practical design the integrated mixer SA612 was used. Input signal to the mixer up to 500 MHz frequency can be used. For required operation external oscillator and fifth-order low pass filter were constructed. Oscillator was designed for fixed frequency 32 MHz. Fifth-order low pass filter was inserted between the mixer and the oscillator, because of filtering higher harmonics. The second aim of the work was measuring double-balanced mixer basic parameters, such as Compression Point (P-1dB) and Intercept Point (IP3). For the IP3 measurement, another one device was required. It consists of the power combiner for mixing two frequency close signals and third-order bandpass filter, which selects required frequency band. Finally, the laboratory equipment was fabricated and its real parameters were measured.

The efficiency of enforcement of anti-covid measures
Bouz, David ; Dušek, Libor (advisor) ; Montag, Josef (referee)
1 The Efficiency of Enforcement of Anti-covid Measures Abstract This thesis evaluates the efficiency of the enforcement of anti-epidemic measures during the covid-19 pandemic in years 2020 to 2022. Although the Czech Republic had managed the first wave of the outbreak in spring 2020 in an exemplary manner, it later showed one of the highest increases in new infection cases relative to population worldwide, as well as a rather high number of excess deaths. Why did the country become one of the most affected regions during the pandemic, even though the anti-covid measures were similar to those in other countries? One possible explanation could stem from the insufficient enforcement of existing anti-epidemic measures by governmental authorities. Based on the data provided by the administrative and police authorities in the territory of Prague for the period between March 2020 and May 2022, this thesis describes the real-life practice in terms of inspections, offence proceedings and subsequent sanctions for violations of anti-epidemic measures. The conclusions are supported by other publicly available information as well. The thesis then undertakes an analysis of the enforcement of anti-epidemic measures through the lens of the economics of crime and G. Becker's rational choice theory. The thesis concludes that...

Empirical analysis of non-pecuniary damage compensation to victims of rape
Vanča, Tomáš ; Dušek, Libor (advisor) ; Čihák, Jakub (referee)
Empirical analysis of non-pecuniary damage compensation to victims of rape Abstract In the last thirty years the image and the position of the victim has changed; as a result, an extra layer has been added to the concept of crime: 'crime' nowadays represents a violation of the public interest, as well as a violation of the individual victim's interest. Also, a limited attention has been paid to the potential of tort law to address the harm of sexual violence. Based on analysis of 350 judicial decision about non-pecuniary damage compensation in rape cases in Czech Republic, this thesis asks: How the criminal courts deal with the monetary claims of the victims, in what amount they awarded them, what rules they use in their decision-making and also what factors play a role in determining the amount. The findings suggest that, in only a third of cases rape victims claims non-pecuniary damage in adhesive proceedings, if they do so, they have a two-thirds chance of succeeding. The courts do not award high non-pecuniary damages, but the victims' claims are not exaggerated either. The regression analysis conclusions reveal that the courts are guided by more by legally relevant factors when determining the amount of non-pecuniary damage, but also reveal statistically significant differences between judicial...

Constitutional definition of the mechanisms of control of territorial self-governing units
Dušek, Libor ; Antoš, Marek (advisor) ; Suchánek, Radovan (referee)
The aim is to answer the question of whether effective control mechanisms exist in the Czech Republic which would guarantee the fulfilment of legal regulations by municipalities and regional authorities dealing with public property. It is also my aim to explore whether such control mechanisms result from the constitutionally guaranteed rights to local government and, if they do, to what extent they may be incorporated in the Czech legislation. My diploma thesis is based on specific case studies, the case law of general courts and the current jurisprudence of the Czech Constitutional Court. After the description of the current state of affairs in the Czech Republic, I further focus on the definition of the control mechanisms of local governments in Czechoslovakia between the two world wars (1918 - 1938) and partly also during the Austro-Hungarian Empire. This diversion leading to this era has been selected to reflect the efforts to resume the local government traditions in the context of the renewal of the local government scheme in the Czech Republic after 1989. It is proven towards the end of the historical survey that unlike today, there were effective control mechanisms available before World War II, with several alternatives. The thesis also compares the legal regulations beyond the control...

Essays on Migration and Trade
Konečný, Tomáš ; Dušek, Libor (advisor) ; Rauch, James (referee) ; Girma, Sourafel (referee)
The unifying theme of my dissertation is access to foreign markets, be it through social networks (immigration), or independent NGO-driven initiatives (Fair Trade). In the first paper, "Immigrant Networks, Trade Creation, and Trade Diversion", I derive a simple gravity model with matching and use data on the foreign-born population located in 19 OECD-member countries to estimate the impact of immigrant links on trade. The relative impact on trade of immigrant networks declines with the GDP of source country and is generally smaller than estimates from preceding studies. The theoretical framework explicitly models forgone bilateral trade and shifts in trade flows due to immigrant links. There is some empirical evidence that immigrant networks change trade flows between countries. The net effect on total trade of a 10-percent increase in the overall immigrant stock varies between -0.12 and 1.18 percent for host countries and -6.99 and 2.58 percent for source countries in the sample. The second essay entitled "Expatriates and Trade" evaluates the contribution to bilateral trade flows of expatriates from the OECD economies living in less developed countries. Similarly to the results of the existing research that focused on immigrants moving in the opposite direction, I find that the expatriates promote trade...

Sentencing in the Czech Republic: An Empirical Investigation
Drápal, Jakub ; Dušek, Libor (advisor) ; van Wingerden, Sigrid (referee) ; Johnson, Brian (referee)
Sentencing in the Czech Republic: An Empirical Investigation Abstract Sentencing is in many respects still terra incognita. This holds true especially for other countries than common law ones and those in the Western and Northern Europe. This dissertation thus empirically studies sentencing practices in the Czech Republic using quantitative methods. It is composed of four articles focusing on various sentencing issues: Firstly, on the influence of judicial experience on sentencing using longitudinal data analyzing judges' trajectories from 2008 onward. It shows that increasing experience reduces inter-judge disparity. Secondly, on analyzing previously underappreciated measure to achieve policy change: Informal authority of the supreme institutions. In 2016 the Prosecutor General's Office and the Supreme Court organized several meetings and seminars for prosecutors and judges in order to persuade them to impose more fines. This paper illustrates that these informal tools might have been underappreciated as they are highly effective. The third paper is dedicated to studying a particular extra-legal characteristics influencing sentencing in Prague: The weather. It builds both on psychological literature showing that weather influences mood and mood often impacts behavior and decision-making and on previous US...

The Protection of Privacy on the Internet: a Law and Economics Perspective
Blatt, Patrik ; Dušek, Libor (advisor) ; Montag, Josef (referee)
The Protection of Privacy on the Internet: a Law and Economics Perspective Abstract The topic of this thesis is protection of privacy on the Internet, further narrowed down to the matter of granting consent to store and process cookies and looking at it specifically from the perspective of law and economics. The aim of this paper is to answer the question of whether the current legislation of granting permission to process cookies is sufficient and user-friendly. To answer this question, the thesis was based on interpretation of the results of a survey about using cookies, conducted on selected Czech websites, namely those of central authorities of the Czech Republic, Czech news portals and Czech online shopping stores. Furthermore, the thesis proposes specific changes within current legislation of processing cookies. Because of the transposition of Directive on privacy and electronic communications into the legal order of the Czech Republic, the policy of granting consent to the storing and processing of personal data has changed from the original opt-out policy to the current opt-in policy. The current opt-in policy requires a preceding user's consent. In this thesis, I conclude that applying this opt-in policy has lowered the user-friendly settings and that it did not lead to any improvement of...
