The male abdominal tubercle varies in height and length, in some specimens being very short, which gives the distal edge of the abdomen a more rounded appearance.</p> <p> <i>Natural history:</i> Very poorly known. Many of the specimens that we studied were collected by pitfall traps. We photographed the webs of four juvenile specimens of <i>P. harveii</i> in the Walpole area (Darling Range). Their horizontal webs were built on the leaf litter in a disturbed area and had a maximum frame width between 52 and 92 mm. These orbs were relatively densely spun, as they had many radii (17–28, mean 22, <i>N</i> = 4), lack split radii, and have numerous spiral turns (Fig. 11). The hub is closed and the temporary spiral is removed in the final web (see Fig. 11D). We observed one of the webs being built at night time.</p> <p> <i>Distribution:</i> Southern Western Australia (see map in Fig. 17).</p> <p> <i>Additional specimens studied:</i> Australia, Western Australia: 1 female, Chesapeake Road at Gardner River, 34°48′S, 116°11′E, 1.v.1990, Harvey, M.

Second chamber of parliament as a veto player in federal and unitary states
No full textDiplomsko delo raziskuje in analizira vpliv določene značilnosti političnega sistema na drugi dom parlamenta. Značilnost političnega sistema v tem primeru je federalnost oziroma unitarnost države. Večina analitikov povezuje federalizem z močno dvodomnostjo, vendar napačno bi bilo predvidevati, da v unitarnih državah drugi domovi parlamentov nimajo pomembne vloge v javnopolitičnem procesu. V prvem delu diplomske naloge so podrobneje opisani ključni pojmi: federalizem, unitarizem in dvodomnost. Kot dodaten vidik je vključena še teorija o veto igralcih, s pomočjo katere lahko bolje razumemo vlogo oziroma moč drugih domov parlamentov v različnih političnih sistemih. V drugem delu pa so predstavljeni drugi domovi parlamentov v treh federalnih in treh unitarnih državah. Raziskava je omejena zgolj na demokratične evropske države, in sicer Avstrijo, Belgijo, Nemčijo, Italijo, Češko in Francijo. Namen diplomskega dela je torej ob primerih iz izbranih držav ugotoviti, kako federalnost oziroma unitarnost države vpliva na drugi dom parlamenta kot veto igralca.The diploma thesis aims to explore and analyse the influence of a certain characteristic of a political system on the second chamber of parliament. The characteristic in this case is whether a country is based on a federal or unitary system. Most analysts associate federalism with strong bicameralism, but it would be wrong to assume that in unitary states, second chambers of parliament do not have a significant role in the policy process. The first part of the thesis describes in more detail the key concepts: federalism, unitarism and bicameralism. As an additional aspect, the theory of veto players is included, with the help of which we can better understand the role and power of second chambers of parliament in different political systems. In the second part, the second chambers of parliament in three federal and three unitary states are presented. The research is limited to democratic European countries, namely Austria, Belgium, Germany, Italy, the Czech Republic and France. Therefore the purpose of the diploma thesis is to determine how the federal or unitary system of a country affects the second chamber of parliament as a veto player based on the cases from selected countries
Georgi Dimitrov and his Cult of Personality in Bulgaria and the Eastern Bloc
No full textTato bakalářská práce je věnována Georgi Dimitrovi. Tento Bulhar vešel do povědomí
lidí už v první čtvrtině 20. století, kdy se účastnil a často i sám pořádal stávky dělníků
v Bulharsku a bojoval za jejich práva. Nicméně asi nejvíce vstoupil do povědomí nejen
Bulharům, ale prakticky celému světu při procesu obhajoby požáru Říšského sněmu v roce
1933, tzv. Lipský proces. Po úspěchu a propuštění z vězení měl od této doby Dimitrov ještě
větší ohlas veřejnosti celého světa. A to mu vydrželo až do konce jeho života, po jeho smrti je
jeho kult rozšířen ještě více a je velmi zajímavé pozorovat, kde všude bylo v té době možné
pozorovat Dimitrův kult osobnosti.This bachelor thesis is dedicated to Georgi Dimitrov. This Bulgarian became known in
the first quarter of the 20th century when he participated and often also organized workers
strikes in Bulgaria and fought for their rights. But he´s mostly known also by foreigners, not
just Bulgarians, thanks to the process of defending the fire of the Reichstag in 1933 called
Leipzig Trial. After his success and release from prison, Dimitrov had received even greater
public recognition ever since around the whole world. And it lasted until the end of his life,
after his death his cult is spreaded even more and it´s very interesting to see at that time it was
possible to observe Dimitrov's personality cult.Fakulta filozofická1. Představení práce studentkou. 2. Přečtení posudků. 3. Rozprava - kritický přístup ke zdrojům, využití dobových učebnic.Dokončená práce s úspěšnou obhajobo
An axiomatic approach to composite solutions
No full textDimitrov D, Haake C-J. An axiomatic approach to composite solutions. Working Papers. Institute of Mathematical Economics. Vol 385. Bielefeld: Universität Bielefeld; 2006.We investigate a situation in which gains from cooperation are represented by a cooperative TU-game and a solution proposes a division of coalitional worths. In addition, asymmetries among players outside the game are captured by a vector of exogenous weights. If a solution measures players' payoffs inherent in the game, and a coalition has formed, then the question is how to measure players' overall payoffs in that coalition. For this we introduce the notion of a composite solution. We provide an axiomatic characterization of a specific composite solution, in which exogenous weights enter in a proportional fashion
TRF2 negatively regulates nucleosome density and organization at human telomeres
No full textTelomeres are the nucleoproteic structures that protect the ends of eukaryotic chromosomes from recombination and degradation. In humans, telomeres consist of several kbp of TTAGGG repeats ending in single-stranded 3’ ends about 150 nt long. Telomeres progressively shorten in replicating cells, as a consequence of end processing and of incomplete DNA replication at chromosome termini, till they reach a critical length that leads to cellular senescence. In germ line cells telomere loss is counteracted by the reverse transcriptase enzyme telomerase, which adds telomeric repeats to the 3’ ends of the chromosomes using as template its RNA moiety. Two hallmarks of cancer can be directly referred to telomeres. First, shortening and/or uncapping of telomeres is one of the main sources leading to the chromosome instability commonly found in cancer. Secondly, in tumors the limitless replicative potential is directly linked to the reactivation of telomerase, or to alternative mechanisms of telomere maintenance.
At the moment, a satisfactory description of telomere organization is still lacking. Double-stranded TTAGGG repeats are organized in tightly spaced nucleosomes and are bound by the specific proteins TRF1 and TRF2, essential for chromosome protection. An unresolved question in the organization of mammalian telomeres is whether specific telomeric proteins compete with the histone octamer for binding to telomeric sequences or whether they cooperate to form a telomeric protective structure. By means of in vitro model systems we previously demonstrated that TRF1 is able to recognize nucleosomal binding sites and to alter nucleosome structure. We show that, unlike TRF1, TRF2 is unable to bind to nucleosomal binding sites, suggesting that TRF2 and the histone octamer compete for binding to telomeres. To investigate how TRF2 interplays with telomeric nucleosomes, we overexpressed TRF2 or a dominant negative mutant in C33A cells by transient lentiviral expression. By means of ChIP analysis and MNase digestion assay we found that the density of nucleosomes at telomeres is inversely correlated with TRF2 dosage. These results are in agreement with in vitro assembly of telomeric nucleosomal arrays by using Drosophila embryonic extracts. Remarkably, when added to the Drosophila extracts TRF2 increases nucleosomal repeat length from 155±5 bp to about 195±5 bp, indicating that TRF2 may preferentially position between nucleosomes. The implication of these findings for telomere stability will be discussed
Analysis of a selected PID line and its proposed optimization
No full textBakalářská práce se zabývá analýzou pražské autobusové linky 110, jejímu významu v rámci města, městských částí, trasovému vedení, souběhu s ostatními linkami a především jejímu reálnému provozu pod taktovkou dopravce. Práce je zaměřena na analýzu logistického uspořádání nasazování vozů dopravce Jaroslava Štěpánka na linku včetně směn a střídání řidičů. Cílem práce je pomocí vhodné metody zjistit, zdali se v současném systému nasazování vozů do provozu nachází neefektivní či neekonomická místa. Ty mohou být zejména v prostojích vozů či řidičů, zbytečnému služebnímu přejíždění či v počtu potřebných vozů pro provoz na lince. K odhaleným slabým místům je cílem navrhnout jejich optimalizaci za účelem snížení nadbytečných nákladů.The Bachelor´s Thesis is concerned with the analysis of the Prague bus line 110, in terms of its significance in context of the city and its districts, route design, connectivity with other lines and mainly its cooperation with the carrier. The work focuses on the analysis of the logistic structure of bus deployment and the scheduling of drivers´ shifts in case of the carrier Jaroslav Štěpánek. The aim of this work is to detect using a suitable method, whether the current system of bus deployment includes inefficiencies and non-economical parts. These parts may exist in the idle times of buses and drivers, service rides and in the number of buses required for the operation of the line. The detected weak parts are to be optimized for the purpose of minimizing unprecedented costs
TRF2 NEGATIVELY AFFECTS NUCLEOSOME ASSEMBLY ON TELOMERIC SEQUENCES
No full textAn unresolved question in the organization of mammalian telomeres is whether specific telomeric proteins compete with the histone octamer for binding to telomeric sequences or whether they cooperate to form a telomeric protective structure. By means of in vitro model systems we previously demonstrated that TRF1 is able to recognize nucleosomal binding sites and to alter nucleosome structure. We show that, unlike TRF1, TRF2 is unable to bind to nucleosomal binding sites, suggesting that TRF2 and the histone octamer compete for binding to telomeres. To investigate how TRF2 interplays with telomeric nucleosomes, we set up a model system to assemble telomeric nucleosomal arrays by using Drosophila embryonic extracts. We found that telomeric nucleosomes are spaced every 155±5 bp, indicating that the short nucleosomal spacing found in vivo is a sequence-dependent feature. Remarkably, when added to the Drosophila extracts TRF2 increases nucleosomal repeat length to about 195±5 bp, indicating that TRF2 may preferentially position between nucleosomes

Výzkum se zabývá 5471 články ze šesti českých médií s různou politickou orientací a využívá smíšený metodický přístup, který kombinuje kvantitativní obsahovou analýzu a kvalitativní narativní analýzu. Cílem je identifikovat a analyzovat prominenci a způsob tvorby narativů o komunistické příslušnosti kandidátů. Pomocí systematického vyhledávání klíčových slov studie odhaluje míru zdůrazňování socialistické minulosti. Výsledky ukazují, že narativy o socialistické minulosti jsou významným tématem v mediálním zpravodajství, přičemž jsou patrné rozdíly v důrazu na ně v různých médiích. Narativní analýza 24 článků odhalila několik dominantních narativů napříč vybranými médii. Studie přispívá k pochopení role historických narativů v současné politice a zdůrazňuje vliv médií na utváření kolektivní paměti. Závěry vyzdvihují zásadní roli médií a jejich redakční politiky při vykreslování minulosti politických osobností. Zdůrazňují také potřebu diferencovaného přístupu k analýze médií v postsocialistických společnostech.Department of JournalismKatedra žurnalistikyFakulta sociálních vědFaculty of Social Science
Pravicový extremismus v Braniborsku 1990-2010
No full textThe bachelor thesis and one case study "Right wing extremism in Brandenburg 1990 − 2010" discusses the different forms of right wing extremism in the federal state Brandenburg in the timeframe of twenty years after the German reunification. The aim of this thesis is the analysis of the development of this phenomenon in Brandenburg in all its forms, reaching from right-wing extremist mindsets over political parties, to groupings and the commission of crimes. But also the persecution of right-wing extremism through the measures taken by the government of Brandenburg and the civil society by the Brandenburg political officials as well as the civil society is handled in the thesis. The author is dealing with the reasons for the spreading of right-wing extremism, points out the interconnection between its constituent forms and verifies the officially declared "stagnating to declining" tendency of right-wing extremist display in Brandenburg. Several conclusions are drawn. The scene is much interconnected despite its heterogeneity, especially with the National Democratic Party NPD. The most immediate danger is posed by right-wing extremist motivated violence, justified by the ideology of the culprits and ranging from threats to murder. The claim about "stagnating to declining" tendency of right-wing...Bakalářská práce a jednopřípadová studie "Pravicový extremismus v Braniborsku 1990 − 2010" se věnuje různým podobám pravicového extremismu ve spolkové zemi Braniborsko v časovém úseku dvaceti let po znovusjednocení Německa. Cílem práce je analýza vývoje tohoto fenoménu v Braniborsku ve všech jeho formách, sahajících od extrémně pravicových postojů, přes politické strany, po uskupení a páchání trestných činů. Práce však zohledňuje i potírání pravicového extremismu skrze angažmá zemské politiky a civilní společnosti. Autorka se věnuje důvodům pro rozšiřování pravicového extremismu v Braniborsku, poukazuje na provázanost jeho jednotlivých forem a ověřuje oficiálně deklarovanou stagnující až klesající tendenci projevů pravicového extremismu ve spolkové zemi. Dochází k závěru, že extrémně pravicová scéna je i přes svou heterogennost jasně propojená, obzvlášť s národně-demokratickou stranou NPD, že největší bezprostřední ohrožení společnosti v Braniborsku však vychází ze strany násilníků, užívajících svou ideologii jako ospravedlnění pro své činy, sahající od vyhrožování až k vraždě. Tvrzení o stagnující až klesající tendenci projevů pravicového extremismu autorka v práci potvrzuje.Department of German and Austrian StudiesKatedra německých a rakouských studiíFaculty of Social SciencesFakulta sociálních vě
