The present thesis investigates the commercial sex hygiene films produced between the years 1914 and 1919 in the United States, during the last years of the Progressive Era. Rejected and prohibited as soon as five years after their apparition, the sex hygiene films’ position within the industry, as well as the cinematic techniques they incorporated, will be analysed through the concept of the Low Other. The first part of the thesis aims to delineate the used concepts, as well as integrate the sex hygiene film into a wider cultural, social, and political framework. The second part explores the films’ aesthetic construction, then focuses on a textual analysis of the narrative and non-narrative methods implied by three particular sex hygiene films. Finally, the thesis concludes that the films used a series of cinematic methods to create a Low Other on-screen, yet these very methods ultimately played a part within their suppression as a Low Other body of culture.

Piscivorous birds are often blamed for causing significant damage to fish stocks. Various methods are used to determine the composition of their food, each of them has limits in its ability to determine the complete food spectrum. This work maps the complete food composition of 14 species of fish-eating birds with a method that is not commonly used. Method used in this work uses analysis of publicly available photos on Google.com. In addition to the complete composition of the food, the species composition of the non-fish part of the prey was also determined, and in the case of the Great Cormorant (Phalacrocorax carbo), also the length of the fishes it catches. The aim of this work is to reveal the usability of this method for these purposes. A total of 2350 retrieved photographs were analyzed. The results obtained by photo analysis are in all cases compared with data in the available literature. For representatives of heron birds (Ardeidae), the analysis of photographs provided good information on the food spectrum of individual birds and on the qualitative composition of the non-fish component. It also provided relatively good information on the diet of the White-tailed Eagle (Haliaeetus albicilla), but the bird part of the prey was slightly underestimated. In the diet of the Great Crested Grebe...
