Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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

ABSTRACT
Background: Dysphagia is a symptom that negatively impacts patients’ quality of life. In the present thesis, aspects of dysphagia were explored in patients with primary achalasia and in patients diagnosed with cancers of the oesophagus or of the gastro-oesophageal junction.
Aims: To validate commonly used dysphagia scores for malignant strictures of the oesophagus; to evaluate surgical and conservative treatments against primary achalasia, as well as evaluate stent treatments for dysphagia in advanced oesophageal cancer; and to describe and evaluate body composition, sarcopenia, and physical performance before and during follow-up after resection surgery in patients with oesophageal cancer.
Methods and results:
Paper I – A randomized controlled trial was performed in which laparoscopic myotomy was compared to endoscopic dilatation for achalasia-associated dysphagia, using treatment failure as the primary variable. At the five-year follow-up, there was a significant difference in favour of the surgical approach with fewer treatment failures. Both dysphagia and QoL were better in the operated group at three years, although these differences diminished at five years. Treatment costs in the operated group were significantly higher.
Paper II – A validation of scales for assessment of dysphagia due to malignancy was made in patients with cancer of the oesophagus. Self-reported dysphagia from the Watson score, Goldschmid score and the Ogilvie score was compared to a food diary and to the already validated QoL questionnaire, QLQ-OG25. All scores had good reliability, and the Ogilvie score and QLQ-OG25 had the strongest correlation.
Paper III – A randomized controlled trial was conducted to explore the potential difference in stent migration between a conventional semi-covered stent, and a fully covered stent of a newer design, in palliative treatment of dysphagia due to malignancy. The primary variable was the frequency of migration > 20 mm. There were no significant differences in any of the studied variables of dysphagia, QoL or re-intervention frequency, indicating that a fully-covered stent of a newer design is similar to a conventional semi-covered stent with regard to migration.
Paper IV – Body composition and sarcopenia were investigated in a prospectively collected patient cohort with cancer of the oesophagus who were planned for surgery with curative intent. Prior to surgery, a majority of the patients displayed deteriorated physical performance; almost two of five were judged to be severely malnourished in spite of a normal BMI, and one of five had sarcopenia. Muscle mass continued to deteriorate for at least three months post-operatively. High physical performance, female sex and a high global QoL score positively predicted overall survival.
Conclusions: The Ogilvie score and the dysphagia module in QLQ-OG25 can be selected for assessment of dysphagia due to malignancy. In primary achalasia, laparoscopic myotomy gives a better long-term result and can thus be recommended as a primary treatment method. A fully-covered stent of a newer design is comparable to a conventional semi-covered stent with regard to migration. Patients with potentially curable oesophageal cancer have a high pre-operative prevalence of malnutrition and sarcopenia in spite of normal average BMI. Surgery has a long-lasting catabolic impact. This highlights the importance of optimal pre- and post-operative nutritional support in oesophageal cancer.

Jan Kapr's contribution to contemporary music : an essay about a composer and teacher
No full textThis creative project is a treatise on a leading personality of Czechoslovakian musical life, the composer, Jan Kapr. The author discusses the following:1. The complicated development of Kapr's career and work, 2. Kapr's method of organization of musical material in a composition, as described in his book Constants,3. His former and current style which is demonstrated in two of his compositions, Concert Variations, for flute and string orchestra and Testimonies for four solo instruments,4. Two of his recent works, Exercises for Gydli and the Symphony No. 7, Country of Childhood.Thesis (M.A.
ELEVEN FACES OF JAN GOGOL, JR.
No full textAuthor Jan Rendl in his thesis attempts to look at the world of ideas and educator Jan
Gogola ml. through the eleven chapters in which each chapter somehow characterizes itself by Jan Gogola ml. and each of them somehow determines its creative ideas of it through the metaphor of a football match when Jan Gogola, with its characters, movies himself a teammate, as well as defensively. It gives goals with their situations as well as occasionally digging his opponents ankles.
Jan Gogola ml. thus embodies one stage of the Department of Documentary Film at FAMU, which often stands at the intersection between teaching activities and Karel Vachek among students who applied by them during their seminars psychological methods that work must be peculiarly associated with the author of the film

Swedish integration policy documents: a close dialogic reading
No full textSweden as the great welfare state where everybody is equally welcomed and cared for has for long been the prevailing view. Although Swedish integration policy seems to confirm this view, this is far removed from many people’s experienced reality. I argue that part of this disharmony lies in how West European languages contain and relate to an ‘identity’ construction, which perpetuates and is perpetuated through dichotomies that strengthen the social and political cogency of concepts such as ‘race’, ethnicity and culture. Based on this, I carry out a discourse analysis of Sweden’s major integration policy documents from the mid 1970s up to today.
After an eclectic reading of discourses on migration and integration terminology, ‘identity’ and language, I assert the centrality of ‘identity’ construction to everything we do. With this in mind, taking the dialogism promoted by the Bakhtinian Circle as the dichotomy to monologism, I carry out a close dialogic reading in the tradition of Lynn Pearce (1994) and Peter Stallybrass and Allon White (1986).
Contextualising the policy documents, I present the history of migration and integration from a Swedish perspective. Focusing on the last five decades, I divide the different historic tendencies into themes ranging from: emigration to labour migration, refugee migration and the European Union, and from immigrant policy to integration policy.
Believing that the conceptualisation and the handling of categorisation, segregation, culture, discrimination and racism are all central to a successful integration policy, I analyse the policy documents thematically accordingly. I show how the interdependence of the common ‘identity’ constructions and language sometimes obscures and frequently counteracts the intention of the author. As a result, I argue that the Bakhtinian Circle holds the key to a better understanding of the invincibility of stereotyping within racialised discourses, through applying absolute ‘identity’ constructions in monologic speech, and how this may be counteracted in order to strive for a dialogic approach to the world
