The article presents a manuscript collection of texts of evangelical provenance that has recently been purchased in a German second-hand bookshop. According to a chronogram, this manuscript is likely to come from 1840. The manuscript consists of fifteen relatively independent text sections thematically related to the denominational controversies before and after the battle of White Mountain. The paper examines possible printed or manuscript models of individual parts and as well as their reflection in both earlier and more recent bibliographic literature. and David Mach.

Description:
V dobách, kdy v obecném povědomí byl termín dislokace znám jen ve spojení "dislokované zlomeniny kostí" či "dislokace pracovníků nebo celých institucí do vybraných prostor", začal Frntišek Kroupa propagovat ve fyzice a materiálovýcha vědách dislokace, čárové poruchy krystalické struktury. Dislokace, původem z matematiky jako označení singularit kontinua, byly zavedeny ve fyzice krystalů ve třicátých letech minulého století a experimentálně byly prokázány až o dvacet let později., Václav Paidar., and Obsahuje bibliografii

Language:

Description:
Hlemýžď pruhovaný (Helix thessalica) je nejnovějším přírůstkem české a slovenské měkkýší fauny. Pozornosti unikal proto, že nebyl rozlišován od velmi podobného a u nás zcela běžného hlemýždě zahradního (H. pomatia). Jeho odlišení umožnily až molekulárněfylogenetické analýzy, ale nakonec se ukázalo, že ho lze dobře poznat i podle ulity a pohlavního ústrojí. V článku jsou detailně popsány všechny determinační znaky odlišující oba druhy, a nově je podrobně zmapováno rozšíření hlemýždě pruhovaného v České republice. Hlemýžď pruhovaný žije především na jihozápadě Balkánského poloostrova, ale podél Karpat zasahuje od Slovenska až na Moravu. Na té se vyskytuje ostrůvkovitě v údolí řeky Jihlavy mezi Mohelnem a Dolními Kounicemi. Na řadě míst se setkává s hlemýžděm zahradním, se kterým se zřejmě kříží. S ohledem na málo známé rozšíření nově nalezeného druhu vyzýváme k jeho dalšímu hledání u nás i na Slovensku., Helix thessalica is the latest addition to Czech molluscan fauna. It has been overlooked because it wasn’t distinguished from the extremely similar and very common Roman Snail (H. pomatia). Only molecular phylogenetics allowed for its recognition, but eventually it turned out to differ in both its shell and genital system. In this paper, the characters differentiating both species are described and the distribution of H. thessalica in the Czech Republic is newly characterised. It lives mainly in the southwestern Balkans, but along the Carpathian Arc it extends up to Slovakia and Moravia, where it occurs in several patches in the Jihlava river valley. Locally, it apparently hybridizes there with H. pomatia. Readers are encouraged to search for new sites of the species in the Czech and Slovak Republics., and Ondřej Korábek, Lucie Juřičková, Adam Petrusek.

49. Identity, activism and hatred: hate speech against migrants on Facebook in the Czech Republic in 2015

Language:

Description:
V roce 2015 se na internetu v České republice zvedla vlna nenávistných projevů proti migrantům, zejména muslimského původu. Tento článek prezentuje výsledky výzkumu nenávistných projevů vůči migrantům a uprchlíkům na Facebooku v České republice v létě 2015. Za pomoci kombinované metody analýzy využívající automatický sběr dat a následnou manuální triangulaci výsledků bylo možné odpovědět na některé základní otázky o procesu vytváření a šíření nenávistných projevů na Facebooku. Je zřejmé, že vlna nenávistných projevů proti migrantům v roce 2015 byla cíleně i nezamýšleně podpořena společnými aktivitami různých uživatelů Facebooku (především mužů ve středním věku příslušejících ke střední střídě), propagandistickými aktivitami extremistických skupin, zpravodajstvím masmédií a také designem samotné komunikační platformy., The increased influx of refugees and migrants to the EU in 2015 has been followed by a noticeable presence of online hate speech against migrants in many countries across Europe. The article presents the results of a study of hate speech proliferation on Facebook in the Czech Republic during the summer of 2015. Its goal is to identify the producers of hate speech and determine their social background, explore the main channels of hate speech proliferation, determine the specific groups of migrants targeted by hate speech, put the hate speech in the context of online political communication, and discuss the role of media and politicians in the process of hate speech proliferation. With regard to the works of Castells, Skocpol or Bennett and Segerberg, online hate speech can be perceived as an extreme variety of new, rapidly evolving modes of political communication as such. Social and political activism has been shifting from membership-based organizations and parties towards flexible movements and initiatives with strong emphasis on the logic of identity politics. People may or may not engage in hate speech production as lone independent actors, but they still perceive their actions as part of larger collective efforts. When we focus on hate speech as a form of civic activism or networking, new interesting patterns can emerge. The study is based on a mixed-method analysis; computer-assisted data collection via the Social Insider software tool was further triangulated by random sampling and subsequent manual coding and analysis of selected Facebook posts, comments and other content. The question of reception and influence of hate speech was largely omitted from the analysis, due both to the research methods chosen and to the inherently cyclical nature of social network communication. Hate speech itself was identified according to a custom-made definition based on various existing legal definitions and scholarly perspectives of legal and media science. The results of the analysis indicate that the wave of hate speech against migrants was aggravated both intentionally and coincidentally by the combined forces of disparate Facebook users, extremist groups´ propaganda, news media and the design of the social network itself. As for the social background of frequent producers of hate speech, there was a strong prevalence of middle-aged and middle-class males, and a significant under-representation of both elderly and young Facebook users. The majority of the hate speech content was produced and spread in small-scale communication exchanges, i.e. under articles posted on individual user profiles etc. The communication activities of larger, well-organized populist groups, political parties or communities were visibly present, but they did not play a significant part in the hate speech production itself - although their possible involvement in agenda setting cannot be underestimated. All the datasets indicated that a vast majority of the hate speech in the given time period was aimed either against migrants in general or Muslims, while these two groups often overlapped. The role of mass media and of the design of the Facebook platform in the entire process should be discussed further. It became apparent that the producers of hate speech themselves seldom created any substantial shared content such as articles or videos. To the contrary, many hateful comments occurred through sharing and subsequent discussion of articles produced by online news outlets. As the Czech mass media are defined by transformation, uncertainty, layoffs and disintegration of professional routines, this creates a dangerous mix that could lead to further proliferation of hate speech., Matouš Hrdina., and Obsahuje bibliografii
