Lineamento regional no norte do Pantanal separando áreas de vegetação fenológica e floristicamente distintas: evidências de diversidade ambiental originada por neotectônica / not available

Ribeiro, Eduardo Francisco 27 April 2017 (has links)
O Pantanal é uma bacia sedimentar quaternária ativa de baixa declividade que vem sendo preenchida principalmente por megaleques fluviais. Apesar de possuir um relevo plano e uma geologia à primeira vista monótona, o Pantanal é um mosaico de ambientes distintos. A presença, intensidade e duração das inundações é considerada a mais importante causa da variabilidade ambiental, implicando que pequenas variações no relevo tenham drástica influência florística e fenológica. Estas variações espacialmente expressivas geram lineamentos de vegetação e captura de drenagens e estão associadas à neotectônica, também responsável pela sismicidade desta bacia. Para analisar este lineamento de vegetação, foram utilizadas diversas fontes de dados, incluindo imagens de sensoriamento remoto, dados de aeromagnetometria e dados florísticos obtidos em campo. A principal ferramenta foi uma série de 15 anos de imagens NDVI do sensor MODIS (345 imagens compostas de 16 dias). Com estas imagens foi abordada a fenologia da superfície terrestre (FSP) na área do lineamento, a qual apresenta uma notável variabilidade. Foram obtidos perfis temporais tanto contínuos como de um ano médio e uma série de métricas fenológicas, as quais foram analisadas com o auxílio de perfis de varredura e dados estatísticos. Os resultados da FSP demostraram a importante senescência associada ao período de seca ocorrendo apenas na porção a SE do lineamento, com a vegetação a NW permanecendo verde mesmo nos meses sem chuvas expressivas. Dados TRMM (2001-2015) mostram não haver grande diferença na pluviosidade da área do lineamento, e, quando comparados aos dados de NDVI, permitiram demonstrar maior relação entre verdor da vegetação e pluviosidade a SE do lineamento e independência do verdor às chuvas locais a NW. Apesar da indicação de que a área NW está mais baixa do que a área SE, isto não pode ser comprovado pelo modelo digital de elevação SRTM. Os dados florísticos obtidos em 17 parcelas de cobertura florestal em avançado estágio de reflorestação foram tratados em três abordagens: ordenação dos índices de similaridade de Jaccard (J), agrupamento hierárquico destes índices e obtenção do J considerando as parcelas feitas de cada lado do lineamento como amostras de uma mesma área (NW e SE). Os dados de geofísica sugerem que este lineamento seja a continuidade de uma zona de falhas a nordeste do Pantanal associada ao Lineamento Transbrasiliano. O conjunto dos dados caracteriza o lineamento estudado como um limite ambiental entre áreas que inundam com diferentes frequências e durações. Em função da extensão, linearidade e contexto tectônico, considera-se que o lineamento seja a expressão na vegetação de falha com componente vertical de rejeito, mostrando a importância da neotectônica na diversidade ambiental do Pantanal. / The Pantanal is an active quaternary sedimentary basin of low slope that is being filled mainly by fluvial megafans. Despite having a flat relief and a geology at first glance monotonous, the Pantanal is a mosaic of different environments. The presence, intensity, and duration of floods are considered the most important cause of environmental variability, implying that small variations in the relief have a drastic floristic and phenological influence. These spatially expressive variations generate vegetation lineaments and stream captures and are associated to neotectonics, responsible for the seismicity of this basin. In order to analyze this vegetation lineament, several data sources were used, including remote sensing images, aeromagnetometry data and floristic data obtained in the field. The main tool was a series of 15 years of MODIS sensor NDVI images (345 composite images of 16 days). With these images, the land surface phenology (LSP) was approached in the region of the lineament, which presents a remarkable variability. Both continuous and one-year average temporal profiles and a series of phenological metrics were obtained, which were analyzed with the aid of swath profiles and statistical data. The LSP results demonstrated the important senescence associated with the drought period occurring only in the SE portion of the lineament, while the NW vegetation remaining green even in the months without expressive rains. TRMM data (2001-2015) showed that there is not a great difference in the rainfall of the region of the lineament, and when compared to the NDVI data, allowed to demonstrate a greater relation between greenness of the vegetation and rainfall to the SE of the lineament and independence of the greenness to the local rainfall to NW. Despite the indication that the NW region is lower than the SE region, this cannot prove by the SRTM digital elevation model. The floristic data obtained in 17 forest plots at an advanced regeneration stage were treated in three approaches: ordering the Jaccard (J) similarity indices, hierarchical clustering of these indices and obtaining the J considering the plots made on each side of the lineament as samples from the same region (NW and SE). The geophysical data suggest that this lineament is the continuity of a fault zone northeast of the Pantanal associated with the TransBrasilian Lineament. The data set characterizes the studied lineament as an environmental boundary between areas that flood with different frequencies and durations. Due to the extension, linearity and tectonic context, it is considered that the lineament is the expression in the vegetation of a fault with vertical displacement component, showing the importance of neotectonics in the environmental diversity of the Pantanal.

Desperate Housewives, miroir tendu au(x) féminisme(s) américain(s) ? / Desperate Housewives, a mirror held up to american feminism(s) ?

Marcucci, Virginie 27 November 2010 (has links)
Ce travail s’attache à étudier les éventuels féminismes de Desperate Housewives. La peinture que la série propose de femmes et mères au foyer américaines désespérées est a priori le lieu d’une dénonciation de leur vie et de leur condition qui n’est pas sans rappeler celle de Betty Friedan dans The Feminine Mystique au début des années soixante. De plus, de nombreuses contradictions du féminisme américain (en fait constitué de nombreuses sous-catégories et sensibilités) y trouvent un écho. Cette multiplicité des interprétations possibles de Desperate Housewives, ainsi que sa composante postmoderne et camp, en font le lieu privilégié d’un féminisme queer propre à la série. / This study investigates the feminist messages conveyed by Desperate Housewives. The depiction of desperate American housewives and stay-at-home mothers seems at first to be a scathing indictment of their plight, not unlike that of Betty Friedan in The Feminine Mystique.Furthermore many inner dissensions of American feminism (a term far more pluralistic than one might think) are voiced in the television series. The different ways Desperate Housewives can be interpreted, along with its postmodern and camp components, make it possible for an idiosyncratic brand of queer feminism to emerge.

"Strong like a woman" : En kritisk diskursanalys av Netflix kategori "Serier med en stark kvinnlig huvudkaraktär" utifrån ett feministiskt medieteoretiskt ramverk

Hellman, Tilda January 2018 (has links)
Uppsatsens syfte är att analysera och problematisera Netflix kategori ”Serier med en stark kvinnlig huvudkaraktär” utifrån valda begrepp inom feministisk medieteori. Det valda teoretiska ramverket och tidigare forskningen låg som grund för hur problemformulering skapats. Den valda metoden var kritisk diskursanalys baserat på den formulerad av Norman Fairclough och genomfördes med hjälp av dennes verktyg den tredimensionella modellen, som undersöker diskursiv praktik och text i relation till den sociala praktiken. Detta kombinerades även med en innehållsanalys för att ge en bredare förståelse för materialet, samt verktyg för att kunna nå en mer övergripande konklusion över kategorins struktur och dess innebörd. Resultatet visade både på en historisk utveckling, men även på en komplex reproduktion av maktförhållanden inom medieproduktion.

Är dunderhonung dopning? : En undersökning av de budskap som förmedlas i samband med idrott i serietidningen Bamse

Cunelius, Erik January 2007 (has links)
Sammanfattning Syfte och frågeställningar Syftet med uppsatsen var att studera och analysera de budskap som förmedlas i samband med idrott i serietidningen Bamse. Frågeställningarna i arbetet var på vilket sätt förmedlingen sker respektive vilka budskap det är som förmedlas.   Metod Datainsamlingen skedde genom textundersökning och bildanalys. Antalet årgångar av tidningen som studerades var sju (mellan år 2001 och 2007). Utöver detta studerades två nummer av Bamse-extra. Samtliga episoder i de angivna utgåvorna lästes igenom, men endast de delar analyserades där något idrottsinslag på ett eller annat sätt var bärande av budskap. En analysmodell användes för att lättare kunna uttolka seriernas fulla innebörder. Modellen har reviderats något men är ursprungligen utformad av Lars Peterson.   Resultat Förmedlingen av budskap sker ibland genom att de tydligt uttalas i episodernas slutskeden. Den kan också ske genom att det görs en klar tudelning mellan goda karaktärer som handlar gott och onda dito som handlar skurkaktigt. På så vis förmedlas vad som är ett handlingsmönster att eftersträva och vad som inte är det. Ett ytterligare sätt som förmedlingen sker på är genom att låta läsaren förstå huruvida olika sätt att handla får önskvärda eller icke önskvärda konsekvenser.   De budskap som förmedlas är att det goda övervinner det onda, att alla ska få vara med, att det (i normalfall) är fel att fuska, att en handling måste alltid ses i ljuset av omständigheterna och de bakomliggande motiven, att tankeförmåga och teknik bringar idrottslig framgång, att personer av kvinnligt kön mycket väl kan vara dugliga idrottare (liksom män kan), att man skall ställa upp för varandra, vara hjälpsam och generös, att den som försöker utsätta någon annan för något elakt eller obehagligt ofta faller offer för gärningen själv, att man skall våga stå för vad man har gjort, att allt inte bör handla om att vinna, att man skall våga delta och inte ge upp, att det oväntade kan vinna samt att man inte skall döma någon på förhand.   Slutsats Budskapen följer en tydlig linje om att man skall handla gott. För att kunna göra det bör man vara öppensinnad, rättrogen, ödmjuk, fördomsfri, eftertänksam, solidarisk, hjälpsam, vänlig, generös, ärlig, trägen och framåt samt ha en känsla för alla individers lika värde. Ett gott handlande leder enligt Bamse till en mer trivsam tillvaro för samtliga. Idrottslig framgång bringas av tankeförmåga och teknik.

Lärarrollen : En studie av yrkets framställning i populärkultur / The Teachers' role : A study of the trade’s description in popular culture

Morin, Åsa January 2012 (has links)
Syftet med uppsatsen är att undersöka hur lärarrollen karaktäriseras i filmer och TV-serier under 2000-talet. I undersökningen görs en framställning av karaktärernas utmärkande drag samt en indelning i kategorierna: The Good, The Saint, The Sad och The Bad. I resultatet ställs karaktärernas drag i förhållande till människosyn och etiksyn. Sist men inte minst dras några tänkbara slutsatser utifrån resultatet. / The purpose of this essay is to highlight how the popular culture, focusing on film and TV-series during the 2000's, describes the characterization of the teachers' role. The survey gives a description of the character´s significant features and the character´s are placed in one of these four categories: The Good, The Saint, The Sad and The Bad. In the result, these features are set in relation to the vision of human beings and the vision of ethics. Last but not least, some conceivable conclusions are drawn from the result.
