Portrait of a regional author - Ladislav Beran
No full textBakalářská práce představuje píseckého rodáka, patriota a spisovatele Ladislava Berana. Část práce mapuje důležitá data jeho života, jeho tvůrčí inspiraci a práci kriminalisty. Zajímalo mě, zda se autor sám považuje za regionálního autora. V práci také analyzuji tři jeho knihy. Shromáždila jsem některé reflexe na tyto knihy, rozhovory s autorem a články o něm. Mým hlavním zdrojem, ze kterého jsem čerpala informace, bylo osobní setkání s autorem.ObhájenoThe bachelor thesis introduces the native of Písek, patriot and writer Ladislav Beran. Part of the paper maps important dates of his life, his creative inspiration and the work of a criminologist. I wonder if the author himself considers himself a regional author. I also analyze three of his books. I have gathered some reflections on these books, some interviews with the author, and articles about him. My main source from which I drew information was a personal meeting with the author
The evolutionary and developmental foundations of mathematics.

Derivatio nominis: Dedicated to the grandfather of the senior author, Stephan Beran. Male description: Head with round eyes, no eyes-bridge, as typical of the subfamily. Antenna 15 segmented (broken in all specimens during preparation, fig 1). Scape short, barrel-shaped, pedicel spherical, shorter than scape. Flagellomeres elongate, slightly asymmetric with a pair of elongate simple ascoids, about 1.3 times longer than a flagellomere. Relative size of basal antennal segments: 28 - 24-53 - 46 - 42 - further distal segments missing; scape length 0.1 mm. Palpus 3 -segmented (fig 2) 0.24mm long. Basal segment with a circular pit (vesicle), with sensory rods. Relative length of the palpus segments: 29 - 19-21. Thorax and legs elongate without specific features. Wing venation is typical of the genus with only a single vein (R 4 + 5) between the forks R 2 /R 3 and M 1 /M 2. It is not clear whether sc terminates into costa or into R 1 and what is the cross-vein. Radial fork slightly distal of medial fork, a cross-vein between the stems of M 1 + 2 and M 3 /CuA 1. CuA 2 elongate, with basal cross-vein to basal stem of M 3 /CuA 1, anal vein short. Wing length 1.88 mm (holotype); 1.93, 2.04 mm (paratypes); 2.02 mm (allotype). Male abdomen with tergites 7 and 8 strongly reduced to thin clasps, sternites of usual size. Segment 8 with a torsion of about 90 ° to segment 7, genitalia with another torsion of 90 ° to segment 8 so that the genitalia become inverted (fig 5). Genitalia complicatedly structured; gonocoxite basally with an elongate dorsal apodeme (da); distally with a long prominent ventral process, along its inner margin covered with a row of strong bristles; at about middle height lies a short and broad process with several tips and with strong setae. Above it the slightly bent and flattened simple gonostyle articulates. Aedeagus consists of a laterally flattened strongly sclerotized aedeagus apodeme and a distal, slightly sclerotized portion (figs 4, 5, 6). The distal portion maybe bend ventrally at an about median position, where the lateral ‘arms’ of the aedeagus (la in figures 5 and 6) are markedly thinner. In a basal position of the aedeagus broad distal sclerites are visible (fig 5), in a distal position these are merely visible because they are fold up and appear as if one looks at a blade tip (fig 4). At the end of the basal aedeagus apodeme a pair of sperm ducts opens into a wide chamber, flanked by the faint sclerites. Tergite 9 rectangular, cerci are in a horizontal plane, elongate triangular, quite large and setose, best visible in lateral view. Female description: specimen of similar size and coloration as male, palpus three-segmented, also with a depression and sensory rods on the basal segment. Sternite 8 triangular with a slight basal incision, the tip loosely covered with setae, cerci oval (fig 7). The inner genitalia consist of a broad ventral apodeme, and an elongate slightly sclerotized plate. Above the plate is a thin long apodeme that is probably joined to the plate. Further, two short sperm ducts that evolve from a single opening are visible. They end in a pair of holes with well sclerotized circular entrance. Whether these are openings of spermathecae remains dubious. Further structures cannot be sufficiently interpreted at the moment. Remarks. Six European species of Trichomyia Haliday, 1839 are known so far: T. urbica Haliday (widespread in Europe), T. parvula Szabó (Hungaria, Germany, Great Britain) (Szabó 1960), T. malickyi Wagner (Greece: Islands of Kefallinia and Euböa; Wagner, 1982, Ježek, 1990), T. kostovi Ježek (Bulgaria; Ježek 1990), T. carlestolrai Wagner (Spain: Barcelona; Wagner 2001) and T. minima (England; Withers 2004). Relations to the already described European species appear minor. The construction of the genitalia, especially the male gonostyli is unique among European taxa. It is still unknown whether specific relationships between certain tree species and Trichomyiinae do exist. However it is remarkable that the discovery sites of recently described European species are related to old forests and single old trees and remainder of old trees with slowly decaying trees and traditional careful forest management. Thus we speculate that quite a number of European Trichomyiinae still remains undiscovered. We will find them probably in the minor remnants of old forests with slowly decaying trees and in nature reserves.Published as part of Beran, Bernadett, Doczkal, Dieter, Pfister, Kurt & Wagner, Rüdiger, 2010, Two new species of Psychodidae (subfamilies Trichomyiinae and Psychodinae) from Germany associated with decaying wood, pp. 59-64 in Zootaxa 2386 on pages 60-62, DOI: 10.5281/zenodo.19377

Greek and Latin medical terminology instruction in programmes of general medicine at medical schools in the Czech Republic and abroad.
No full textTITLE: Greek and Latin medical terminology instruction in programmes of general medicine at medical schools in the Czech Republic and abroad. AUTHOR: Aleš Beran DEPARTMENT: Department of Education SUPERVISOR: doc. PhDr. Miroslava Váňová, CSc. ABSTRACT: The thesis seeks to provide a systematic description of the Greek and Latin medical terminology instruction at Czech and foreign medical schools. Its main objective is to build a platform for implementations of instructional innovations. In the first part of the thesis the medical terminology instruction in the Czech Republic is contextualized by giving a historical overview of development of medical terminology and dealing with origins of its instruction at the Faculty of General Medicine in Prague. The view of a present state of the instruction is completed by a profile of a typical medical student, which is based on the questionnaire. The next part of the thesis consists of detailed content analyses of selected Czech and foreign textbooks and their comparison. Based upon these analyses, an original typology of instructional models is set up which can be considered to be the most important theoretical outcome of the thesis. The typology is subsequently used as a tool for description of teaching medical terminology in Austria, Germany, United States, Canada,..
The Theoretical Concepts of Rights and Their Protection in Cyberspace
No full textof Master's Thesis The Theoretical Concepts of Rights and Their Protection in Cyberspace Author: Veronika Jirková Supervisor: doc. JUDr. Karel Beran, Ph.D. Department: Department of Legal Theory and Legal Doctrines This master's thesis is focused on questions regarding the concept and protection of users' rights in cyberspace. This thesis concerns the notion of cyberspace, regulatory systems in it, and finally the extent and protection of rights in cyberspace. The aim of this thesis is, first, to analyse the situation of protection of rights in cyberspace, and second, to identify the ways to improve this situation. This thesis is subdivided into four parts. The first part is of descriptive nature. It covers some fundamental concepts related to the topic. It describes the notion of cyberspace, the notion and structure of the Internet and the actors who play a role in governance of the Internet. The second part is aimed at regulatory systems. It describes regulatory systems in both online world (cyberspace) and offline world. These two groups are then compared. Finally, this part demonstrates the impact of the identified discrepancies on practical examples. The third part relates to the extent of rights in cyberspace. It tries to choose an appropriate theoretical method and it discusses the..
