Stoppa matcherna! : En jämförande undersökning av två tidningars gestaltningar av händelserna i samband med Davis Cupmatcherna i Båstad 1968 och 1975

Lind, Rasmus January 2021 (has links)
This essay sheds light on the protest events in connection with the Davis-Cup matches in Båstad in 1968 and 1975. They are relatively close in time, touch on the same sports competition, similar issues, engage largely the same group of protesters and were the subject of enormous media interest. When looking at the events in Båstad in a retrospective light, the event in 1968 is reflected much more strongly than the event in 1975, in this essay this imbalance will be examined in more detail. The main purpose of the essay is to, based on articles in Svenska Dagbladet and Dagens Nyheter, comparatively investigate how these newspapers may have shaped the historical image of the events in connection with the Davis Cup matches in Båstad in 1968 and 1975. The theoretical framework is based on framing theory, which shows how media's representations of reality affect people's perceptions, how media, in some ways but not others, reproduces and disseminates different power centers’. The choice of the theoretical framework rests on the thesis that the newspapers' depiction of the events created a historical picture of them. The newspapers visualize the reality according to preferences that they find to be rewarding now. The essay's methodological starting point is both quantitative and qualitative as it consists of a conventional content analysis on the one hand and is inspired by a quantitative four-step model that is connected to the framing theory on the other. The results show that the framings of the newspapers can be linked to the different course of events of the protests, as well as the modernization of social institutions, in particular sports. In 1968, the white sport was still white, but the events in Båstad nullified the possibility of seriously claiming that sports and politics did not influence each other. The similar framings of the newspapers in 1975 also show how far the abolition of authority had come. Sport was opened to the world and to politics, modernized and democratized and is today more democratically governed than before.

Entanglement a Nestorův pohár / Entanglement and Nestor's cup

Horáček, Stanislav January 2019 (has links)
(in English): Archeology is a science interpreting the past. In every interpretation of the past, there are some conceptual assumptions present that may be imperceptible at first sight. The aim of this primarily theoretical work is to make these assumptions more visible. The thesis is mainly based on the renowned archaeologist Ian Hodder, whose work is presented on the contrast between processual and postprocessual archeology. The greatest attention is paid to Hodder's current theory of Entanglement, which combines the work into one whole and sets its overall tone. Entanglement is a theory dealing with relationships and dependencies between people and things. Interpretation, critical evaluation and summary of related approaches is successively presented. Theory of Entanglement is set within a broader framework of archaeological theoretical discourse, which can be termed as relational archeology. The common denominators of relational archaeologies are the emphasis on relations, interest in the materiality of things and the effort to confront dualisms, such as the relationship of locality and globality. Symmetrical archeology primarily based on the work of Bruno Latour is introduced in one of the chapters. The final section in the spirit of Hodder's theory and relational archaeology deals with the...

Gradientní segmentace snímků očního pozadí / Gradient boosted segmentation of retinal fundus images

Goliaš, Matúš January 2021 (has links)
Title: Gradient boosted segmentation of retinal fundus images Author: Matúš Goliaš Department: Department of Software and Computer Science Education Supervisor: Doc. RNDr. Elena Šikudová PhD., Department of Software and Computer Science Education Abstract: Over the recent years, there has been an increase in the use of automatic methods in medical diagnosis. A significant number of publications have analysed eye disorders and diseases. One of the most severe eye conditions is glaucoma. It damages optic nerves and causes gradual loss of vision. An essential step towards a faster diagnosis of this disease is accurate segmentation of the optic disc and cup. This task is difficult due to many retinal defects, different image acquisition techniques, and artefacts caused by imaging devices. This thesis describes an iterative threshold-based algorithm for extraction of the optic disc. An objective function quantifying object similarity to the optic disc is defined to direct the iteration. Following that, we introduce a superpixel-based classification algorithm for extraction of the optic cup. We propose the use of gradient boosted decision trees which outperform random forest and support vector machine. In addition, we evaluate the proposed algorithms and their alternatives on a publicly available retinal fundus...

Analysis of men’s sprint prologues in cross-country skiing World Cup : An outlook of how the best male skiers approach the sprint prologues

Persson, Anton, Panisi, Gilberto January 2020 (has links)
SyfteDenna studies syfte var att undersöka om det finns ett samband mellan mellantid och sluttid på sprint prologer för herrar i världscuptävlingar, samt undersöka om förklaringsgraden för detta samband skiljer sig mellan tävlingsbanor med olika banprofil baserat på antal höjdmeter fram till mellantiden (CTC).MetoderAnalysen gjordes genom att ladda ner samtliga resultat från prologer från världscupen innehållande en mellantid efter 500-1000 m från säsongen 2017/2018 till 2019-2020. Sluttid, slutplacering och tid och placering vid mellantidsstation användes i den statistiska analysen. CTC beräknades genom att dividera klättrade höjdmeter från start till mellantid med respektive banas distans från start till mellantid. Baserat på olika banors CTC delades banorna in i 2 grupper, Level 1 (L1) banor med CTC ≤ 0,040 m/m och Level 2 (L2) CTC > 0,040 m/m. För att bestämma om datan var normalfördelad användes Kolmogorov-Smirnov test. Datan analyserades sedan med hjälp av Pearsons korrelation för att beräkna korrelationskoefficienten (r) vilken sedan kvadrerades för att få förklaringsgraden (r2).ResultatKorrelationsanalysen som genomförts visar ett signifikant resultat mellan mellantid och sluttid för alla analyserade prologer (0,63 < r < 0,95; alla p < 0,001). Mellantiden förklarar 76 ± 12 % av variationen i sluttid, men ingen signifikant skillnad sågs för förklaringsgraden mellan tävlingsbanor med olika CTCSlutsatserSlutsatserna som kan dras av denna studie är att ett bra resultat vid mellantiden med stor sannolikhet kommer ge ett bra slutresultat, oberoende av banprofil. Framtida forskning behövs för att utvärdera vilken taktik åkarna väljer. / PurposeThe aim of this present study was to investigate if there is any correlation between intermediate station time and finish time in men’s cross-country ski sprint World Cup prologue. The second purpose was to identify if the correlation could depend on the morphology of the analysed courses. Methods Analyses were made on sprint prologues in World Cup, involving an intermediate time after 500-1000m from season 2017/2018 to 2019-2020. Intermediate time and finish time were used in statistical analysis. A coefficient of terrain characteristics (CTC) was calculated by dividing the high difference (HD) from the start to the position of the intermediate time station by the respectively covered distance. Based on CTC the different courses were categorized in two groups. Leve 1 (L1) courses with a CTC ≤ 0,040 m/m and Level 2 (L2) courses with a CTC > 0,040 m/m. To identify if data were normally distributed Kolmogorov-Smirnov test was used. The data were analysed using Pearson’s correlation to calculate the coefficient of variation (r) which was then squared to obtain the coefficient of determination (r2).ResultsThe correlation analysis shows that there were significant relationships between intermediate time and finish time for all analysed sprint prologues (0,63 < r < 0,95; all p < 0,001). Intermediate time explains 76 ± 12 % of the variation in finish time, while no significant difference was seen for the determination coefficients between race tracks with different CTCConclusionsFast times at the intermediate time stations will most likely give good finish times, independent of terrain characteristics (CTC). Further researches are needed to evaluate which pacing profile skiers are using.

Proyecto nutrifish / Proyect Nutrifish

Ato Mejía, Marco, Ingas Espiritu, Bryan Cesar, Llontop Perez, Miguel David, Yauri Yaringaño, Jhovana 29 November 2019 (has links)
Nutrifish es un proyecto que nace de la idea de brindar nutrición a los consumidores, entre ellos, su principal público objetivo son las madres amas de casa encargadas de llenar las despensas del hogar. A lo largo del camino, encontramos dificultades, pros y contras de realizar la comercialización del producto, sin embargo, con las herramientas y conceptos básicos aprendidos a lo largo de la carrera, pudimos determinar que el balance era positivo y la rentabilidad atractiva. Nutrifish fue el resultado de realizar una lluvia de ideas, las cuales abarcaban desde temas de salud, hasta opciones lúdicas, por ende, los cimientos del proyecto eran bastante débiles, se fueron fortaleciendo a medida que tomábamos conocimiento sobre el mercado de productos precocinados y el manejo interno de sus marcas. A continuación, les mostraremos el camino recorrido por nuestro grupo de trabajo. / Nutrifish is a proyect born from the idea of taking nutrition to a certain number of costumers, its main target are the housewifes, in charge of filling the house storerooms. Along the way we’ve found some difficulties, pros and cons of the commercialization of the product, however, the tools and basic concepts learnt to this day, we found ourselves able to establish a positive balance and an attractive profitability. Nutrifish was the result of a brainstorming, the group went from healthy themes to playful options, thus, the foundations of the project were certainly weak, and we strengthened them by taking knowledge of the precooked food market and the internal management of their brands. In the following paragraphs, we’ll show you the way taken by our work group. / Trabajo de investigación

The influence of drinking games on drinking behavior, psychosocial variables, and harmful behaviors

Touhy, Carol M. 01 January 2010 (has links)
College student alcohol use is a major public health concern in the United States due to high personal (e.g., risky sexual behavior, alcohol poisoning) and societal (e.g., driving under the influence) costs associated with this behavior. Drinking games have emerged as a significant influence on heaviness and frequency of college student drinking. The purpose of this study was to learn more about drinking games on college campuses using data from an intervention study targeting a primarily undergraduate student population of heavy drinkers. Specific research questions were: (1) What are the most common types of drinking games observed on a large state university campus?; (2) Are specific demographic and psychosocial variables related to playing drinking games and the choice of drinking game?; (3) Are there gender differences in drinking behavior?; (4) Are specific harmful behaviors (e.g., drunk driving) related to playing drinking games and the choice of drinking game? Research questions were addressed using a secondary data analysis conducted with baseline data from an intervention study targeting heavy drinkers using university health services at a large state university (n = 363; NIAAA grant #1 U18 2AA015673- 0l). Data were collected using a self-administered questionnaire. Demographic (age, gender, ethnicity, grade level, GPA), psychosocial data (church attendance, significant life event, stress level, depressed/hopeless, loss of pleasure) and harmful behaviors (fighting, not do homework, miss school or work, driven after 3 or more drinks, ridden with someone who drank 3 or more drinks, regrets) were collected using close ended items. Drinking game data were collected using a free response measure (respondents listed up to 5 drinking games they regularly played). Additionally, drinking behaviors (age first use alcohol, in high school how many days in 30 drink 4-5 drinks in a row, currently how many days in 30 drink 4-5 drinks in a row, in past 30 days greatest amount of drinks in a row, in typical week how many days drunk) were also collected using a free response measure. In preparation for data analysis, drinking game data were coded using 6 categories identified by Bosari, et al (2004; motor skills, verbal skills, gambling, media, team, consumption) and an additional category, board (board games). Research questions were addressed using descriptive statistics, chi-square tests. The results of this study indicate that 7 6% of the respondents play drinking games. Of those who play drinking games motor skills games (Beer Pong 70.3%), gambling games (Circle of Death (34.8%), F*** the Dealer (14.5%), and A **hole (10.9%)), and team games (Flip Cup 38.8%) were the most common types of drinking games. Gender, age, educational year, and ethnicity were all associated with type of drinking game (p < .05). Depression and feelings of hopelessness lasting at least 30 days was significantly associated with an increased likelihood of involvement in consumption games and attending religious services was associated with a decreased likelihood of involvement in consumption games (p < .05). Harmful behaviors were significantly associated with participation in drinking games (p < .05). As freshman and younger persons were more likely than others to play the different types of drinking games and the five most popular drinking games tl\is places them at risk for accidents, injury or death. Colleges and Universities need to provide programs to incoming freshman educating them about the risks involved in heavy or frequent alcohol consumption. Additionally, "don't drink and drive" campaigns must become stronger and include a "don't ride with someone who is driving drunk" component because almost 60% of respondents have driven a motor vehicle after having 3 or more drinks and 71.4% have ridden in a motor vehicle with someone they knew had three or more drinks. Finally, as 25% of the respondents started drinking before the age of 15, early intervention is needed to educate children about alcohol and the risks of heavy and frequent drinking. An alcohol awareness program should be started for elementary school children in the same way stop smoking programs have been implemented at early ages.
