The effect of urbanization on life-history strategies in birds
Houšková, Karolína ; Sedláček, Ondřej (advisor) ; Poláková, Simona (referee)
Urbanisation process is recently a wide-spread process that causes high-impact environmental transformation. Habitats affected by urbanization tend to change substantially and ongoing changes influence organisms living in this environment. Urban environment modifies many abiotic conditions (e.g. temperature, artificial light and noise) and biotic factors (e.g. food supply, parasite prevalence, predation pressure) in comparison to natural habitats. In this manner, especially urban bird populations have recently gained broad attention by an increasing number of ecologists. Urban avoiders - typically sensitive and specialized bird species often vanish from urbanized landscapes. However, many bird species were able to colonize urban environment and coexist successfully with man. Populations of birds living in such a new type of environment show many characteristics different from populations living in original habitats. The objective of this work is to review current studies about changes of life strategies in urban bird populations such as modifications of acoustic signals, differences in reproductive and food ecology and physiological or behavioural responses.

Substitution Treatment: Subutex
Sýkorová, Milada ; Dočkal, Jan (advisor) ; Poláková, Simona (referee)
Bachelor's thesis named "Substitution treatment - Subutex" introduces a reader with possible solution of opioid addiction theme, where one of the possible treatments is the replacement with Subutex preparation. Thesis is divided into seven sections. First one deals with the drug policy in the Czech Republic. Next part informs the reader with harm reduction approach in general that includes substitution treatment as well. Thesis presents goals, types and providers of the substitution treatments as well as two lately prescribed medicaments in the Czech Republic: Subutex and Suboxone. After eight years from its registration in 2000 Subutex has turned from being the solution to the problem of opiates addiction. As a result of it a new remedy to deal with these problems has been introduced this January. It bears name Suboxone. The last section introduces into users experience. The thesis looks at the issue from the users' point of view using qualitative inquiry method among clients treated with Subutex. This inquiry tries to learn about clients' experience with the session in general, conditions and with rules imposed by the attending physician, together with its breaching if there is any.

Methods of mapping and monitoring invasive (selected alien) species - monitoring
Pergl, Jan ; Dušek, J. ; Hošek, M. ; Knapp, M. ; Simon, O. ; Berchová, K. ; Bogdan, V. ; Černá, M. ; Poláková, S. ; Musil, J. ; Sádlo, Jiří ; Svobodová, J.
The project aims at problematic invasive species and their prioritization. In the methods we define several groups of aliens for monitoring. In the project are shown the rough financial costs.

The Connection Between Stock Market Volatility and a Position of Economy in a Business Cycle
Poláková, Soňa ; Veselá, Jitka (advisor) ; Krabec, Tomáš (referee) ; Onder, Štěpán (referee)
Finding significant relation between stock markets (including omnipresent volatility) and real economy of the US, Germany, Great Britain and Japan is the main aim of this thessis. If not found it is also the final conclusion. By means of time series analysis using artificial neural networks from the beginning of 2000 till the November of 2014 was proved that the strong single -- way relation between prime stock indices and GDP of chosen economies does exist. Highest quality of prediction was proved on the American and British economy. S&P 500, FTSE and VIX indicator made a precise prediction of future economic progress in the US and Great Britain for six to nine months ahead with 71% to 86% accuracy. The artificial neural networks proved an extraordinary ability to predict chosen financial time series regardless the actual position in a business cycle.

Applications of neural networks and Elliot´s waves on selected shares
Polaková, Soňa ; Veselá, Jitka (advisor) ; Musílek, Petr (referee)
Using modern methods of share quotations forecasting is the main goal of this thesis. The special accent is placed on forecasting the trend by means of artificial neural network especially on the optimalization of variables in the training process. Elliot's wave theory is applied in the second part of the thesis, particularly on prediction of future share quotation progress. Buying or selling signal generated by these two methods is consequently compared with ex-post signal yielding a profit. Lastly, successfulness of using these methods for forecasting at stock market is evaluated.

Technická analýza vybraných akciových titulů
Polaková, Soňa ; Radová, Jarmila (advisor)
Cílem této práce je analyzovat vývoj kurzů zvolených akcií za posledních 18 měsíců a prostřednictvím optimalizovaných parametrů funkcí jednotlivých nástrojů (klouzavých průměrů, oscilátorů a objemových indikátorů) zhodnotit, zda je vybraná metoda výhodnou investicí a zda umožňuje v následujících 6 měsících dosáhnout většího výnosu než prostá metoda Buy and Hold.
