Resfeber : Berättelser från semesterns barndom 1938−1959 / Bitten by the Travel Bug : Tales from the Early Days of Vacation, 1938−1959

Lewén, Aurora January 2017 (has links)
The dissertation provides an in-depth analysis of Swedes’ perceptions about vacations during the period of 1938 to 1959. The aim is to contribute to a more thorough understanding of vacation-related consumption, which in Sweden was of growing economic importance from the 1930s and onwards. The study examines perceptions about the relationship between vacation and work; the experience with nature; interactions with family members and other social relations; relaxation and rest, and the act of travelling. The dissertation also analyzes the adoption of the first Holiday with Pay Act in 1938 and examines how people vacationed during the period. Throughout the study class and gender are used as analytical categories. The principal source material is autobiographical recollections, which consist of written replies to questionnaires sent out by the Nordic Museum. Other sources include materials related to the introduction of the Holiday with Pay Act, mainly the Swedish Government Official Report and the parliamentary debate. Representations of vacations in magazine advertisements are also analyzed. Equalization between classes was an important reason for the adoption of the Holiday with Pay Act in 1938. Proponents of the legislation in parliament and, to some extent even the opponents, viewed equalization as a positive outcome of the reform. As a result of the legislation, blue-collar workers, both women and men, were able to enjoy vacations to a greater extent than before. However, large groups, mainly farmers, entrepreneurs, and housewives, continued to lack entitlement to paid vacations, a fact that were debated in parliament. Nevertheless, persons without legal entitlement to paid vacations still occasionally took time off and went on vacations. It was relatively common to travel during the vacation, even at the beginning of the period. The desire to experience a contrast to everyday life was prominent. People desired contrast not only with work but also with everyday life outside of work, including regular leisure time, something that is particularly evident in the autobiographical recollections. In one form or another, the desire for contrast permeated views on the various factors examined in the dissertation. Travel represented an ideal way to experience contrast. Nature was more interesting if it was located somewhere else, relaxation and rest was best achieved if one went away, and meeting new people was seen as more exciting than spending time with family. Overall perceptions concerning vacation were similar among blue-collar and white-collar workers of both sexes, as well as among housewives, farmers, and entrepreneurs. They all wanted to experience a contrast to everyday life. On a more detailed level, though, these desires took somewhat different forms depending on working conditions and economic circumstances. These common perceptions had economic significance, as going away meant more purchases than staying at home. It was not just a matter of spending what was required for the trip to happen. Travel and the desire for contrast had amplifying effects on other vacation-related consumption as well. An English summary of the dissertation is provided. / I centrum för avhandlingen står en analys av semesteruppfattningar år 1938–1959. Syftet är att på så sätt bidra till en mer ingående förståelse av semesterkonsumtionen, som fick en allt större ekonomisk betydelse från 1930-talet och framåt. Aspekter som undersöks närmare är uppfattningar om semester i relation till arbete, naturuppsyn, uppfattningar om familj och andra sociala relationer, uppfattningar om vila samt uppfattningar om resande. Vid sidan om den fördjupande analysen av uppfattningar studeras även införandet av semesterlagen 1938 och det konkreta semesterfirandet under perioden. Genus och klass utgör analytiska kategorier genom hela avhandlingen. Huvudmaterial är så kallade frågelistsvar. Dessa är självbiografiska minnen nedskrivna av informanter som svar på en frågelista Nordiska museet skickat ut. Dessutom används material med anknytning till semesterlagstiftningens införande, främst semesterutredning och riksdagsprotokoll, samt semesterrelaterade annonser i veckotidningarna Husmodern och Lektyr. När riksdagen fattade beslut om semesterlagen 1938 var ett viktigt motiv att man ville utjämna skillnader mellan klasserna. Både de som var positiva till reformen och de som var negativa till reformen såg klassutjämning som ett positivt resultat av den. Fler arbetare, både kvinnor och män, fick nu också semester. Samtidigt fanns stora grupper, främst jordbrukare och företagare av båda könen samt hemarbetande hustrur, vilka inte hade några semesterrättigheter alls, något som också debatterades i riksdagen. Det hände dock att kvinnor och män utan semesterrättigheter ändå tog ledigt på egen bekostnad. Det var relativt vanligt att resa iväg på semestern, även i början av perioden. I frågelistsvaren syns en stark uppskattning av att få uppleva en kontrast till vardagen. Ett liknande synsätt kom till uttryck i utredningen, i riksdagsdebatten och i de semesterrelaterade annonserna. Avhandlingen visar att informanterna ville uppleva en kontrast både till arbete och till övrig vardagsfritid. Synsättet präglade semesteruppfattningarna gällande alla aspekter som studerats närmare. Naturen sågs som mer intressant om den var belägen någon annanstans än hemmavid, vila och avkoppling ansågs bäst kunna uppnås om man reste iväg någonstans och semesterfirarna uppskattade att göra nya bekantskaper medan familjen snarare togs för given. Genom att resa iväg på semestern kunde informanterna uppfylla önskemålet om att få uppleva kontrast till hela sin vardag. Avhandlingen visar att semesteruppfattningarna på en övergripande nivå var lika bland arbetare, tjänstemän, hemarbetande hustrur, lantbrukare och företagare. På en mer detaljerade nivå kunde önskemålet att få uppleva en kontrast till vardagen ta sig något olika uttryck beroende på semesterfirarens arbetsförhållanden och ekonomiska situation. Avhandlingen visar dessutom att uppfattningarna hade ekonomisk betydelse, då resor innebar att informanterna gjorde fler inköp än då de stannade hemma. Det handlade inte enbart om sådan konsumtion som krävdes för att resan skulle bli av, utan även andra typer av inköp var större i samband med en resa än vid en hemmavistelse.

Magnetic resonance imaging of resting cerebral oxygen metabolism : applications in Alzheimer’s disease

Lajoie, Isabelle 02 1900 (has links)
The BOLD contrast employed in functional MRI studies is an ambiguous signal composed of changes in blood flow, blood volume and oxidative metabolism. In situations where the vasculature and metabolism may have been affected, such as in aging and in certain diseases, the dissociation of the more physiologically-specific components from the BOLD signal becomes crucial. The latest generation of calibrated functional MRI methods allows the estimation of both resting blood flow and absolute oxygen metabolism. The work presented here is based on one such proof-of-concept approach, dubbed QUO2, whereby taking into account, within a generalized model, both arbitrary changes in blood flow and blood O2 content during a combination of hypercapnia and hyperoxia breathing manipulations, yields voxel-wise estimates of resting oxygen extraction fraction and oxidative metabolism. In the first part of this thesis, the QUO2 acquisition protocol and data analysis were revisited in order to enhance the temporal stability of individual blood flow and BOLD responses, consequently improving reliability of the model-derived estimates. Thereafter, an assessment of the within and between-subject variability of the optimized QUO2 measurements was performed on a group of healthy volunteers. In parallel, an analysis was performed of the sensitivity of the model to different sources of random and systematic errors, respectively due to errors in measurements and choice of assumed parameters values. Moreover, the various impacts of the oxygen concentration administered during the hyperoxia manipulation were evaluated through a simulation and experimentally, indicating that a mild hyperoxia was beneficial. Finally, the influence of Alzheimer’s disease in vascular and metabolic changes was explored for the first time by applying the QUO2 approach in a cohort of probable Alzheimer’s disease patients and age-matched control group. Voxel-wise and region-wise differences in resting blood flow, oxygen extraction fraction, oxidative metabolism, transverse relaxation rate constant R2* and R2* changes during hypercapnia were identified. A series of limitations along with recommended solutions was given with regards to the delayed transit time, the susceptibility artifacts and the challenge of performing a hypercapnia manipulation in cohorts of elderly and Alzheimer’s patients. / Le contraste BOLD employé dans les études d’imagerie par résonance magnétique fonctionnelle (IRMf) provient d’une combinaison ambigüe de changements du flux sanguin cérébral, du volume sanguin ainsi que du métabolisme oxydatif. Dans un contexte où les fonctions vasculaires ou métaboliques du cerveau ont pu être affectées, tel qu’avec l’âge ou certaines maladies, il est crucial d’effectuer une décomposition du signal BOLD en composantes physiologiquement plus spécifiques. La dernière génération de méthodes d’IRMf calibrée permet d’estimer à la fois le flux sanguin cérébral et le métabolisme oxydatif au repos. Le présent travail est basé sur une telle technique, appelée QUantitative O2 (QUO2), qui, via un model généralisé, prend en considération les changements du flux sanguin ainsi que ceux en concentrations sanguine d’O2 durant des périodes d’hypercapnie et d’hyperoxie, afin d’estimer, à chaque voxel, la fraction d’extraction d’oxygène et le métabolisme oxydatif au repos. Dans la première partie de cette thèse, le protocole d’acquisition ainsi que la stratégie d’analyse de l’approche QUO2 ont été revus afin d’améliorer la stabilité temporelle des réponses BOLD et du flux sanguin, conséquemment, afin d’accroître la fiabilité des paramètres estimés. Par la suite, une évaluation de la variabilité intra- et inter-sujet des différentes mesures QUO2 a été effectuée auprès d’un groupe de participants sains. En parallèle, une analyse de la sensibilité du model à différentes sources d’erreurs aléatoires (issues des mesures acquises) et systématiques (dues aux assomptions du model) a été réalisée. De plus, les impacts du niveau d’oxygène administré durant les périodes d’hyperoxie ont été évalués via une simulation puis expérimentalement, indiquant qu’une hyperoxie moyenne était bénéfique. Finalement, l’influence de la maladie d’Alzheimer sur les changements vasculaires et métaboliques a été explorée pour la première fois en appliquant le protocole QUO2 à une cohorte de patients Alzheimer et à un groupe témoin du même âge. Des différences en terme de flux sanguin, fraction d’oxygène extraite, métabolisme oxydatif, et taux de relaxation transverse R2* au repos comme en réponse à l’hypercapnie, ont été identifiées au niveau du voxel, ainsi qu’au niveau de régions cérébrales vulnérables à la maladie d’Alzheimer. Une liste de limitations accompagnées de recommandations a été dressée en ce qui a trait au temps de transit différé, aux artéfacts de susceptibilité magnétique, de même qu’au défi que représente l’hypercapnie chez les personnes âgées ou atteintes de la maladie d’Alzheimer.

Získávání informací o uživatelích na webových stránkách / Browser and User Fingerprinting for Practical Deployment

Vondráček, Tomáš January 2021 (has links)
The aim of the diploma thesis is to map the information provided by web browsers, which can be used in practice to identify users on websites. The work focuses on obtaining and subsequent analysis of information about devices, browsers and side effects caused by web extensions that mask the identity of users. The acquisition of information is realized by a designed and implemented library in the TypeScript language, which was deployed on 4 commercial websites. The analysis of the obtained information is carried out after a month of operation of the library and focuses on the degree of information obtained, the speed of obtaining information and the stability of information. The dataset shows that up to 94 % of potentially different users have a unique combination of information. The main contribution of this work lies in the created library, design of new methods of obtaining information, optimization of existing methods and the determination of quality and poor quality information based on their level of information, speed of acquisition and stability over time.
