Behavioral Activity and Hypoxia Tolerance of African Weakly Electric FishMucha, Stefan 16 February 2023 (has links)
In dieser Arbeit wurden die Morpho-Physiologie und das Verhalten zweier Arten Afrikanischer schwach elektrischer Fische, Marcusenius victoriae und Petrocephalus degeni, im Labor und in einem ihrer natürlichen Habitate im Lwamunda Sumpf in Uganda untersucht. Die zwei Hauptziele dieser Arbeit waren (i) tageszeitabhängige Verhaltensrhythmen (Aktivität, Habitatnutzung) im Labor und im Freiland zu untersuchen und (ii) die Ausprägung und Plastizität der morpho-physiologischen Merkmale von P. degeni zu untersuchen, die ihnen erlauben bei natürlich vorkommender, geringer Sauerstoffverfügbarkeit (Hypoxie) zu überleben.
Tageszeitabhängige Verhaltensrhythmen beider Arten wurden im Labor über 42 Stunden und im natürlichen Habitat dieser Fische für sechs Tage erfasst. In den Laborversuchen verbrachten beide Arten tagsüber annähernd 100% der Zeit in einem bereitgestellten Versteck und schwammen nachts heraus um aktiv ihre Umwelt zu erkunden. Im Habitat wurden die meisten Fische in strukturell komplexen Habitaten unter schwimmenden Pflanzen detektiert. Nachts schwammen die Fische aktiv in die offenen und ungeschützten Bereiche der Lagune, vermutlich um nach Futter zu suchen und zu interagieren. Die Begleitende in-situ Messung der Sauerstoffverfügbarkeit zeigte, dass beide Arten präsent und vermutlich sogar am aktivsten waren während Phasen extremer nächtlicher Hypoxie.
Zur Untersuchung der respiratorischen Merkmale von P. degeni wurden Respirometrieversuche mit hypoxie-akklimatisierten Tieren durchgeführt, Hämoglobin- und Laktatkonzentration im Blut gemessen, und morphologische Parameter an den ersten beiden Kiemenbögen erfasst. Die Fische zeigten niedrige Sauerstoffverbrauchsraten, welche sie bis zu einem sehr niedrigem äußeren Sauerstoffpartialdruck aufrechterhielten. Zusätzlich zeigten sie hohe Hämoglobin- und Laktatkonzentrationen im Blut. Bis zu 75 Tage Normoxie-Akklimatisierung führte zu reduzierter Hämoglobinkonzentration und kürzeren Kiemenfilamenten. / In this thesis, I investigated the morpho-physiology and behavior of two species of African mormyrid weakly electric fish, Marcusenius victoriae and Petrocephalus degeni, in the laboratory and in one of their natural habitats, the Lwamunda Swamp in Uganda. The two main objectives of this work were to (i) observe behavioral rhythms and habitat use patterns of both species under natural and laboratory conditions, and (ii) assess expression and plasticity of morpho-physiological traits that might enable P. degeni to survive naturally occurring low oxygen conditions (hypoxia).
Behavioral rhythms were recorded in the laboratory over 42 hours and in the habitat on six sampling days. In the laboratory, both species spent close to 100% of the time in their shelter during the day and actively explore their environment at night. In the swamp lagoon, fish were most often encountered in structurally complex habitats under floating vegetation and ventured into open and unsheltered areas of the lagoon at night, presumably to forage and interact. Concomitant in-situ oxygen measurements revealed that these fish were present, and presumably most active during periods of extreme nocturnal hypoxia in their swamp habitat.
To investigate respiratory traits of swamp-dwelling P. degeni, I conducted respirometry experiments and measured blood lactate and hemoglobin and gill morphometrics on the first two gill arches. Fish showed low routine oxygen consumption rates, which they maintained until a very low ambient oxygen partial pressure was reached. Additionally, they had high concentrations of hemoglobin and lactate in their blood. Up to 75 days of normoxia exposure reduced blood hemoglobin and gill filament length.

Surveying imperialism : the English-Canadian press and British imperial conduct in Africa 1880-1885Brothman, Brien 25 April 2018 (has links)
Cette thèse examine les attitudes de la presse canadienne anglaise face à l'impérialisme britannique pendant les premières années du partage de l'Afrique (1880-1885). Se basant sur une analyse qualitative des éditoriaux de presse, cette étude examine le concept d'impérialisme dans le contexte de l'historiographie canadienne. Profession de surveillance de la société, le journalisme de l'ère victorienne se montre intéressé aux questions du comportement public des gens, de l'ordre politique et de l'harmonie sociale. Ces préoccupations ressortent aussi dans les écrits journalistiques au sujet de la rivalité impérialiste entre l'Angleterre et les autres puissances européennes, et aussi dans les discours sur les politiques et gestes de la Grande-Bretagne à l'égard des peuples et territoires africains. L'interprétation des données suggère que l'appui des journalistes canadiens au comportement britannique en Afrique (et parfois le comportement français et allemand) s'explique non seulement par des sentiments d'appartenance et des liens constitutionnels avec la Grande-Bretagne mais aussi par plusieurs autres facteurs qui forment d'une certaine façon une idéologie impérialiste: classe sociale, politique intérieure, influences intellectuelles et statut et rôle professionnels. En guise d'introduction au sujet principal, les deux premiers chapitres traitent des aspects politiques, culturels, et intellectuels des relations impériales entre le Canada et la Grande-Bretagne aussi bien que du rôle des journalistes dans la société canadienne pendant l'ère victorienne. Les autres chapitres couvrent l'élection britannique de 1880 et la première guerre des Boer; l'intervention et occupation anglaise en Egypte et la crise au Soudan; les différends anglo-français au sujet de Madagascar et la crise diplomatique anglo-allemande relative à L'Afrique du sud-ouest. Dans un dernier temps, la Conférence de Berlin est étudiée. / This thesis examines the attitudes of the English-Canadian press to British imperial conduct during the early years of the partition of Africa (1880-1885). Based on a qualitative analysis of press editorials, this study reconsiders the meaning of the concept of imperialism in the context of Canadian historiography. With one of its primary functions being to survey the behaviour of individuals in society, the press often revealed a preoccupation with questions of public conduct, public order and social harmony. These interests also emerge in the journalistic discourse on Britain's imperial competition with the other European powers in Africa as well as in their writing on Britain's actions and policies with regard to various African peoples and territories. The interpretation of the evidence suggests that some Canadian journalists supported British imperial conduct in Africa (and sometimes French and German imperialist behaviour). This support can be explained not only by sentiments of loyalty and the existence of constitutional ties to Great Britain but also by a series of other factors that gave this imperialist ideology its shape: social class and aspirations, domestic political moods and interests, intellectual influences and professional role and status. By way of introduction to the principal subject, the first two chapters review the political, cultural and intellectual aspects of Canada's imperial relationship and discuss the role of journalists in Victorian Canada. The four following chapters analyze the press coverage of various episodes related to the partition: the British election of 1880 and the Anglo-Boer War, 1880-1881; Britain's involvement in Egypt and Sudan; Anglo-French antagonism over Madagascar and Anglo German rivalry in Southwest Africa, and finally, the Berlin West Africa Conference. / Québec Université Laval, Bibliothèque 2013

Ett diadem och dess ikonografi : En studie av kejsarinnan Josephines pärl- och kamédiadem i porträtt mellan 1812 och 2010 / A Diadem and its Iconography : A Study of Empress Josephine’s Pearl and Cameo Diadem in Portraits between 1812 and 2010af Klinteberg, Kristina January 2021 (has links)
The main purpose of this study of a pearl and cameo diadem, given by Napoleon to his first wife Josephine in 1809, is to follow its representation in portraiture from Paris in 1812 to Stockholm in 2010, and explore how the iconography develops during these 200 years. From the earlier years, the diadem is found only in miniatures, then after coming to the new royal family in Sweden, the Bernadottes, it is given a role of an heirloom representing history and families in grand paintings, arriving to the present well-known wedding hairpiece, covered by modern media, where the diadem is more of a crown than the open, forehead-covering piece of fashion jewellery it was during the Napoleonic era in France. The portraits from 1812, 1814, 1836, 1837, 1877, 1976, 2000/2003 and 2010 also portray a development of the female role model of its time. Just like the hair piece attains an iconography which comprises not only the highest dress codes but also a possibility of status transformation for the people involved in ceremony, the role of the country’s First Lady is about to change into a higher, more egalitarian position of present days.

The importance of counter-culture in art and lifeOrtlieb, Paulina Elizabeth 03 February 2015 (has links)
Punk rock provided not only a watershed of creativity, innovation and a do-it-yourself spirit to a culture saturated in the mainstream, it physically brought like-minded people together in a community, or rather extended family, which in today’s hyper-d.i.y. culture, is progressively declining. As early as the 1940s, theorists such as Adorno and Horkheimer warned us about alienation in a society increasingly dependent on technology. By looking to punk, and other resilient and robust counter-cultures, perhaps we can find solutions to the pitfalls of the ‘culture industry’ (Adorno, Horkheimer, 1944).
My thesis, consisting of a feature-length documentary film and textual analysis, is a culmination of: ethnographic research into the punk scene in my own community; theoretical research into the sociology, ethnography and subculture theory; and my own subjectivity. My personal findings are presented to offer insight into punk philosophy and to spur discourse, rather than deliver an objective account or didactic reproach. / Graduate
