Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
Changes in trade relations between the European Union and the United Kingdom after Brexit and their impact on British automotive industry
This bachelor's thesis aims to evaluate changes in the post-Brexit trade relations between the United Kingdom and the European Union and assess the impact of the new trade conditions implemented under the Trade and Cooperation Agreement (TCA) on the British automotive industry and its development in the new trade environment. The thesis utilizes a combination of quantitative and qualitative research designs. The first chapter explores fundamental concepts of trade liberalization, economic integration and risks associated with transforming trade policies providing a theoretical foundation for subsequent chapters. The second chapter examines both Brexit and the TCA and assesses their impacts on trade relations. The third chapter focuses on the British automotive industry. It includes analysis of statistical data and evaluates how Brexit and TCA have influenced production volumes, investment decisions and export dynamics in this sector. The final chapter also includes a SWOT analysis of the British automotive industry in the new trade environment offering an overview of the industry's position after Brexit and TCA implementation.Bakalářská práce si klade za cíl zhodnotit změny v obchodních vztazích mezi Velkou Británií a Evropskou unii po Brexitu a vymezit, jak nové obchodní podmínky, které byly implementovány po Dohodě o obchodu a spolupráci (TCA), ovlivňují britský automobilový průmysl a jeho vývoj v novém obchodním prostředí.

Variations on the Author
“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
Cellular and molecular factors in the pathogenesis of systemic autoimmunity and comorbidities
Sjögren’s syndrome (SS) and systemic lupus erythematosus (SLE) are systemic rheumatic autoimmune diseases having a major impact on patient’s wellbeing. Besides fatigue, pain and direct damage to exocrine glands in SS, and various target organs, such as skin, joints, kidneys and brain in SLE, these diseases confer an increased risk of lymphoma development and can cause an autoimmune condition in the foetus of pregnant patients, termed neonatal lupus.Several cell types and cytokines contribute to the autoimmune process, with central roles for B cells and autoantibodies. Mature B cells are attracted to the sites of inflammation by chemokine CXCR5. Recent studies identified CXCR5 as a susceptibility gene in SS, and a decrease in expression of CXCR5 on circulating B cells in SS patients, however, the link between the polymorphisms in the CXCR5 locus and B cell trafficking wasn’t addressed. We therefore explored the expression of the chemokine on lymphocytes in peripheral blood and minor salivary glands in SS patients. Confirming the previous findings, our results demonstrate reduced CXCR5 expression in circulating B cell pool, coinciding with the accumulation of CXCR5-positive cells in the salivary glands of the patients. We conclude that the observed decrease in CXCR5 expression in SS results from relocation of CXCR5-highly-positive B cells from blood stream to the salivary glands.T follicular regulatory (TFR) cells also express CXCR5, and the frequency of circulating TFR was suggested a biomarker of degree of tissue inflammation and autoantibody production in SS and rheumatoid arthritis. We could confirm the elevated frequencies of TFR in the blood of SS patients, and show that most of them have a naïve phenotype. B cells are producers of the SS hallmark autoantibodies against Ro and La, that have been used for diagnostic purposes for decades. In this thesis we investigated the anti-inflammatory and anti-proliferative properties of TRIM21/Ro52, one of the targets of anti-Ro. We studied the role of Trim21 in the homeostasis of mouse B cells, and the relevance of TRIM21 as a prognostic marker in diffuse large B-cell lymphoma. In Trim21 knockout mice, B cells had a higher rate of proliferation, follicular B cells were expanded and higher levels of both IgM and IgG were generated after immunization with both thymus dependent and independent antigens engaging the B cell receptor. In accordance with these data, maintained TRIM21 expression was associated with a better prognosis in diffuse large B-cell lymphoma, independently of subtype and underlying autoimmune disease.Another severe comorbidity in SS and SLE affects foetuses and newborns of the patients. Maternal Ro and La autoantibodies are transferred to the developing foetus, and in 2% cases this leads to a congenital heart block (CHB), a part of neonatal lupus. Here, we studied signs of inflammation in the cord blood of neonates exposed to maternal anti-Ro/La. We observed an elevation of serum type I interferon (IFN) levels and an IFN-gene signature in autoantibody-exposed neonates. Besides, neonatal PBMC proved to be capable to produce IFN in vitro, suggesting a possible foetal origin of the cytokine. Further, we show increased frequencies of circulating natural killer cells, and presence of type II IFN in the sera of some of these newborns. These novel findings contribute to the understanding of the mechanisms behind CHB.In summary, we connect genetic variants of the CXCR5 gene locus to expression patterns and cell compartmentalization in SS, demonstrate a role of the autoantigen TRIM21 in B cell homeostasis and function and present evidence for innate immune activation in Ro and La autoantibody-exposed newborns.List of scientific papersI.
