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

July 2007, Germany, Bavaria, Munich, Reitschule [48 °09’ 18 ” N, 11 ° 35 ’ 22 ” E], 511 m, CDC-light trap, leg. B. Beran. 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

The Empirical Properties of Some Popular Estimators of Long Memory Processes
No full textWe present the results of a simulation study into the properties of 12 different estimators of the Hurst parameter, H, or the fractional integration parameter, d, in long memory time series. We compare and contrast their performance on simulated Fractional Gaussian Noises and fractionally integrated series with lengths between 100 and 10,000 data points and H values between 0.55 and 0.90 or d values between 0.05 and 0.40. We apply all 12 estimators to the Campito Mountain data and estimate the accuracy of their estimates using the Beran goodness of t test for long memory time series.Strong dependence; global dependence; long range dependence; Hurst parameter estimators

No full textThe aim of this study is to determine the impact of the Teams Games Tournament (TGT) method on the learning interest in Indonesian language among fourth-grade students at MI Al Falah ‘Beran, Ngawi. The study utilizes a quantitative research methodology and employs a One Group Pretest Posttest Design. The subjects related to the research object form the population. The population in this study comprises all students of MI Al Falah Beran Ngawi, totaling 600 students. The sample in this study consists of 27 fourth-grade students at MI Al Falah Beran. A questionnaire was used to collect data. In this study, the results of data analysis and the paired sample t-test demonstrate a significant impact of the TGT method on the interest in learning Indonesian among fourth-grade students at MI Al Falah Beran. Before the intervention, the students' learning interest was low; however, after the application of the TGT method, there was a significant change in the students' learning interest. This indicates that the TGT model has a positive impact on the students' desire to learn Indonesian language in fourth grade at MI Al Falah Beran
BENK: The Beran Estimator with Neural Kernels for Estimating the Heterogeneous Treatment Effect
No full textA method for estimating the conditional average treatment effect under the condition of censored time-to-event data, called BENK (the Beran Estimator with Neural Kernels), is proposed. The main idea behind the method is to apply the Beran estimator for estimating the survival functions of controls and treatments. Instead of typical kernel functions in the Beran estimator, it is proposed to implement kernels in the form of neural networks of a specific form, called neural kernels. The conditional average treatment effect is estimated by using the survival functions as outcomes of the control and treatment neural networks, which consist of a set of neural kernels with shared parameters. The neural kernels are more flexible and can accurately model a complex location structure of feature vectors. BENK does not require a large dataset for training due to its special way for training networks by means of pairs of examples from the control and treatment groups. The proposed method extends a set of models that estimate the conditional average treatment effect. Various numerical simulation experiments illustrate BENK and compare it with the well-known T-learner, S-learner and X-learner for several types of control and treatment outcome functions based on the Cox models, the random survival forest and the Beran estimator with Gaussian kernels. The code of the proposed algorithms implementing BENK is publicly available
