Development of the real estate market in the years 2012 - 2022 in the Czech Republic (II)
No full textPráce se zabývá vývojem realitního trhu v České republice v letech 2012-2022. Je rozdělená na dvě části, teoretickou a praktickou. V teoretické části je popsán vývoj na realitním trhu a činitele, které na něj působily, porovnáva ho s vývojem v ostatních státech EU a také mezi regiony České republiky. V praktické části jsou zpracována data z nejmenované realitní kanceláře. Cílem práce je zjistit, které proměnné nejvíc ovlivnily cenu nemovitostí a sestavit model, který by co nejlépe predikoval cenu za m2 prodané nemovitosti. V praktické části je použitý statistický software R.The thesis deals with the development of the real estate market in the Czech Republic in the years 2012-2022. It is divided into two parts, theoretical and practical. The theoretical part describes the development of the real estate market and the factors that influenced it, comparing it with the development in other EU countries and also between the regions of the Czech Republic. In the practical part, data from an unnamed real estate agency is processed. The goal of the thesis is to find out which variables have the biggest influence on the price of real estate and to build a model that would predict the price per m2 of sold real estate the best. In the practical part statistical software R is used
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Search for the remnant of plastid in the cell of Rhabdomonas sp.
Get PDFPhylum Euglenozoa contsists of four groups - Euglenoidea, Kinetoplastea, Symbiontida and Diplonemea. Phototrophic euglenids, which constitute a clade, possess green plastid acquired via secondary endosymbiosis from green alga related to recent genus Pyramimonas. According to generally accepted plastid-late hypothesis, the endo- symbiosis took place after split between phototrophic euglenids and all other euglenozo- ans. Endosymbiotic event is always associated with gene transfer from endosymbiont to nuclei of host. Even if the endosymbiont is completely lost we should be able to observe enrichment of the host genome with the genes derived from endosymbiont. Some recent phylogenetic analyses uncovered genes related to green algae in trypanosomas (Kineto- plastea: Trypanosomatida). Based on this observation, authors postulated a hypothesis that the plastid was present already in common ancestor of kinetoplastids and euglenids and was lost in kinetoplastids and some euglenids including osmotrophic Rhabdomonas costata. During analysis of transcriptome of R. costata we found 63 genes, which could originated from green (24 genes) or other (49 genes) algae. In phylogenetic trees only one was robustly related to green and four were robustly related to other algae. Since the number of genes related to..
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

Quantitative Analysis of Gene Ancestry in Euglenoidea
No full textGenes, units of genetic information, are passed from one individual to another, typically within the same species from parents to offspring. Occasionally, genes can be transferred to different species through a process called horizontal gene transfer (HGT). Endosymbiosis is a process in which one organism engulfs another organism and the genes flow between the two symbionts in a process called endosymbiotic gene transfer (EGT), which is a subtype of HGT. Eventually, the endosymbiont may become an organelle such as a mitochondrion or a plastid. Euglenids (Euglenoidea) are unicellular eukaryotes with diverse modes of nutrition - phagotro- phy (e. g., Peranema), osmotrophy (e. g., Rhabdomonas), mixotrophy (phagotrophy and phototrophy in Rapaza), and phototrophy (possessing plastids; e. g., Eutreptiella). The history of endosymbioses of green algae (especially Chlorophyta) and ancestors of Euglenophyceae (including Rapaza) is complex. In my thesis, I performed the quantitative analysis of gene ancestry (QAGA) based on transcripto- mic data of Euglena gracilis showing contribution of closely related Kinetoplastea (1,420 genes, 3.88 % of transcripts inherited vertically), and contribution of multiple "unrelated" (mainly) phototrophic organisms, e. g. Viridiplantae (572, 1.57 %), or Haptophyta (234, 0.64..
Transfer of genetic information between parasite and its host
Get PDFHorizontal gene transfer (HGT) is considered a rare evolutionary event. It can take place between unrelated organisms that coexist in an intimate symbiotic relationship. Such relationship have some parasites with its host. HGT between eukaryotic parasite and its host was identified in some holoparazitic and hemiparazitic plants, the most important human protozoan parasites, microsporidias, human blood-flukes, parasitoids and fruit flies
