Fallet “ASAP Rocky” : En kvalitativ innehållsanalys av gestaltningen av kändisskap och våldsbrott i svensk nyhetsrapportering

Eld, Marika, Karlsson, Hanna January 2021 (has links)
In the summer of 2019, ASAP Rocky, or Rakim Meyers as his real name is, was suspectedand later convicted of assault after a gig in Stockholm. The incident and the subsequent courtproceedings received a great deal of attention in the Swedish media.The purpose of this bachelor thesis was to examine the news coverage of the case "ASAPRocky" in the Swedish press. The research questions that were investigated were: How isASAP Rocky presented in news articles in Dagens Nyheter and Aftonbladet? What does the conformation of the role as a victim and perpetrator look like? How does the conformation change during the arrest? We conducted a qualitative content analysis using a question template based on four questions taken from media logic and framing theory. By examining the portrayal of the parties involved and roles as victims and perpetrators, we were able to distinguish that none of the roles are portrayed or lived up to the definition of the roles.One theme in the essay was that ASAP Rocky's celebrity status was in his favor. This theme is also demonstrated when ASAP is embodied in the empirical material.

Main street evolved: envisioning a comprehensive approach to main street redevelopment in small mountain communities

Murner, Cory James January 1900 (has links)
Master of Landscape Architecture / Department of Landscape Architecture/Regional and Community Planning / Blake M. Belanger / The main streets of the Rocky Mountain West are the social, economic, and cultural centers of their respective communities. Often, these main streets may deteriorate or become abandoned as a result of edge shopping malls and strip style economic development. Thus, a downtown or main street redevelopment effort by the community can help to ensure these economic centers remain. Yet, too often, the redevelopment efforts are oversimplified and fail to integrate the most current street development principles and design initiatives that can benefit not only the community but also the surrounding environment. I n the modern American city, almost half of all daily trips are less than three miles and a third are under one mile. (McCann 2010) “These are distances easily traversed by foot or bicycle, yet 65 percent of trips under one mile are made by automobile.” (McCann 2010) This mobility trend has led to the foundation of programs and organizations that try to promote non-motorized travel. Although these initiatives respond to the human/physical environment, they are far from comprehensive. Today, an integration of smart ecological ideals is essential. How can the revitalization efforts of Rocky Mountain communities be guided to ensure they consider not only the built environment; but also the natural environment? The face of the future main street will be multi-modal and ecologically responsible. Yet, there is presently no clear method of combining the two. A union of the multi-modal principles behind Complete Streets and the ecologically responsible ideals green infrastructure can provide a framework for a new and more inclusive redevelopment approach. The merging of modern ecological and street design principles can lead to a comprehensive Main Street redevelopment program and therefore successfully guide the revitalization efforts of small Rocky Mountain communities in a way that is responsive to future development needs as well as the cultural and ecological aspects of the region. Main Street Evolved will provide a set of tools to guide Colorado Rocky Mountain Main Street redevelopment efforts by providing strategies and implementation guidelines that focus on balancing multi-modal ideals and ecological stormwater management techniques within a small-town mountain context.

Characterization of wet and dry deposition to the nitrogen sensitive alpine ecosystems in the Colorado Rocky Mountains

Oldani, Kaley Michelle January 1900 (has links)
Master of Science / Department of Civil Engineering / Natalie Mladenov / The Colorado Front Range of the Rocky Mountains contains undeveloped, barren soils, yet in this environment there is strong evidence for a microbial role in increased nitrogen (N) export. Barren soils in alpine environments are severely carbon-limited, and organic carbon (OC) is the main energy source for heterotrophic microbial activity and sustenance of life. Atmospheric deposition can contain high amounts of OC. Atmospheric pollutants, dust events, and biological aerosols, such as bacteria, may be important contributors to the atmospheric OC load. In this stage of the research we evaluated seasonal trends and annual loadings in the chemical composition and optical spectroscopic (fluorescence and UV-vis absorbance) signatures of wet deposition and dry deposition in an alpine environment, at Niwot Ridge in the Rocky Mountains of Colorado to better understand the sources and chemical characteristics of atmospheric deposition. Dry deposition was found to be an important source of OC to the alpine. Wet deposition contributed substantially greater amounts of dissolved ammonium, nitrate, and sulfate. There were also positive relationships between dissolved organic carbon (DOC) concentrations and ammonium, nitrate and sulfate concentrations in wet deposition, which may be derived from such sources as dust and urban air pollution. We also observed the presence of seasonally-variable fluorescent components in atmospheric samples that are different from aquatic dissolved organic matter (DOM). Finally, the quality of atmospheric organic compounds reflects photodegradation during transport through the atmosphere. These results are relevant because atmospheric inputs of carbon and other nutrients may influence nitrification in barren, alpine soils and, ultimately, the export of nitrate from alpine watersheds.

Aspectos biogeográficos e paleogeográficos de costões rochosos de Ubatuba - São Paulo / Biogeographic and paleogeographic aspect of Ubatuba\'s rocky coast (São Paulo)

Vilano, Wagner Ferreira 18 November 2013 (has links)
Dentre os ecossistemas presentes na região entre-marés e habitats da zona costeira, os costões rochosos são considerados um dos mais importantes por conter uma alta riqueza de espécies de grande importância ecológica e econômica. Desta forma estudos biogeográficos e paleogeograficos são importantes ferramentas para o entendimento dos padrões de distribuição da biota: o espaço (área geográfica de ocorrência dos organismos), o tempo (eventos históricos que influenciaram os padrões atuais de ocorrência) e a forma dos grupos de organismos. Este estudo teve como objetivo principal abordar a distribuição da biota relacionando-a com a geologia e a morfologia dos costões rochosos alem de caracterizar a presença de indicadores de paleoníveis marinhos de três costões rochosos localizados nas Baías do Flamengo e da Fortaleza, em Ubatuba (SP). Os resultados desse estudo indicam que as distribuição da fauna foi muito homogênea sendo encontrado em todos os costões estudados as cracas do genêro Chtamalus, Balanus e Tetraclita, moluscos do genêro Thais, Littorina (mais abundantes), alem de colonias de Phragmatopoma e extensas bancos de algas do gênero Sargassum que estiveram presentes durante toda amostragem. A ocupação das zonas pela biota vai depender mais do declive da rocha do que da composição mineralógica, juntamente com o regime de ondas atuante no local, que vai ditar a amplitude das faixas de ocupação dos organismos, essa inclinação da rocha pode diretamente interferir nos padrões de distribuição, alterando a taxa de substituição das espécies. Um grupo de moluscos gastrópodes vermetideos do gênero Petaloconchus merece especial destaque, pois, foi registrada a primeira ocorrência deste grupo no Estado de São Paulo, além disso seu remanescentes fósseis são importantes indicadores de paleoníveis marinhos. As estimativas de variações de nível do mar foram mais eficientes com a utilização de vermetídeos e paleotocas de ouriços somada as medições de campo dos vermetideos vivos e sua localização geográfica, permite determinar paleoníveis mais precisos, foram registrados níveis mais elevados no período de 3810 ± 30 Cal. anos AP, atingindo o máximo de 3,87m ± 0,5 m e o menor em 1340 ± 30 Cal. anos AP, registrando 1,00m ± 0,5 m. / Among the ecosystems in the region and intertidal habitats of the coastal zone, the rocky shores are considered one of the most important because it contains a high number of species of great ecological and economic importance. Thus paleogeographic and biogeographic studies are important tools for understanding the distribution patterns of biota: space (geographical area of occurrence of organisms), time (historical events that influenced the patterns of occurrence) and the form of groups of organisms.The present study aimed to approach the distribution of biota relating it to the geology and morphology of rocky coasts in addition to characterize the presence of indicators of marine paleolevels three rocky shores located in Bays Flamengo and Fortaleza, Ubatuba (SP) . The results indicate that the distribution of the fauna was very homogeneous being found in all the studied shores, barnacles of the genus Chtamalus, Balanus and Tetraclita, clams genus Thais, Littorina (most abundant), in addition to extensive colonies Phragmatopoma and banks Sargassum algae that were present during the whole sampling. The occupation of areas for biota will depend more on the slope of the rock that the mineralogical composition, together with the active wave regime in place that will dictate the extent of occupancy ranges of organisms, the inclination of the rock can directly interfere with the patterns distribution changing the rate of substitution of species. A group of gastropod mollusks vermetids of the genus Petaloconchus deserves special mention because it was the first recorded occurrence of this group in the State of São Paulo, besides its fossil remains are important indicators of marine paleolevels. Estimates of changes in sea level were more efficient with the use of vermetid and paleotocas urchins added field measurements of vermetid alive and their geographic location, to determine paleolevels most accurate, highest levels were recorded in the period 3810 ± 30 Cal. years BP, reaching a maximum of 3.87 m ± 0.5 m lower in 1340 ± 30 Cal. years BP, registering 1.00 m ± 0.5 m.

\"Biomonitoramento de costões rochosos instrumento para avaliação de impactos gerados por vazamentos de óleo na região do Canal de São Sebastião - São Paulo\" / Rocky Shore biomonitoring ? Instrument for oil spill impact evaluation on the São Sebastião Channel Region ? São Paulo ? Brazil.

Milanelli, Joao Carlos Carvalho 22 December 2003 (has links)
O Canal de São Sebastião, localizado na costa norte de São Paulo, na região dos municípios de Ilhabela e São Sebastião, é uma das mais importantes zonas costeiras do Estado de São Paulo, em termos de biodiversidade. O Terminal Marítimo Almirante Barroso ? Dutos e Terminais do Centro-Sul (TEBAR/ DTCS) da PETROBRAS está localizado nesta região, na qual ocorreram 151 vazamentos de óleo ligados ao transporte marítimo entre 1978 e 2002. O monitoramento dos costões rochosos do Canal de São Sebastião foi criado pela CETESB para levantar dados de base sobre as comunidades de costões entremarés visando subsidiar futuras avaliações dos impactos de vazamentos de óleo na região. Foram monitorados 17 costões durante quatro anos, entre 1993 e 1996. Constatou-se a presença de 287 táxons (macrofauna e macroalgas), com marcante variação na composição de espécies entre os costões. A estrutura taxonômica de grandes grupos e trófica, no entanto, mantiveram-se relativamente homogêneas entre os pontos. Apesar de haver algumas diferenças locais, o padrão geral de zonação foi similar entre os costões, variando principalmente a largura dos estratos e a composição das espécies acompanhantes. As variações quantitativas das espécies dominantes foram intensas entre os pontos e reduzidas sazonalmente. Os parâmetros ambientais identificados como mais significativos no controle da estrutura da comunidade foram hidrodinamismo, declive, e quantidade de refúgios na rocha. Foram constatadas preferências diferenciadas pelas espécies dominantes por combinações ambientais específicas. / The São Sebastião Channel, located at the north coast of São Paulo State, between the cities of Ilhabela and São Sebastião, is one of the most important coastal zones of the State regarding biodiversity. The Almirante Barroso maritime terminal TEBAR/DTCS is located at this area, where 151 oil spills occurred over the last 25 years. The São Sebastião Channel rocky shore monitoring program was created in order to generate background data about the intertidal community and to support future evaluations of ecological impacts from oil spills. Seventeen sites were monitored during four years (1993-1996). This program registered 287 taxa (macrofauna and macroalgae), and great variation on the species composition among the sites. However, the taxonomic and trophic structure was very similar. Despite the occurrence of individual differences, such as belts width and the composition of the less dominant species, the general pattern of vertical zonation was similar among sites. The quantitative variations of the dominant taxa were intense among the different rocky shores but small seasonally. The environmental variables identified as the most important to the community structure were the hydrodynamics, slope and rock heterogeneities (refuges). The existence of an ecological gradient reflecting the environmental preferences of the dominant species was clearly indicated in this study.

The biogeography and conservation status of the rocky plateaus of the northern Western Ghats, India

Thorpe, Christopher John January 2018 (has links)
Rocky plateaus are globally threatened ecosystems and the lateritic plateaus in northern section of the Indian Western Ghats/Sri Lanka Biodiversity Hotspot (NWG) are notable landscape features. The NWG are geologically distinct from and biologically isolated from the other two sections of the Western Ghats. The NWG is known to possess elevated levels of endemic flora their biotic relationships remain poorly understood. We present here the first quantitative multi-taxa comparative study of plateau fauna in the northern Western Ghats. Ants, water beetles and amphibians were selected for the comparison as they use different ecological resources from each other and at various times of year therefore may provide a wider representation of plateau usage. Distribution and endemism were expected to reflect distribution and isolation by plateau and inter-plateau environment related to elevational, latitudinal, climatic and land-use clines. The study explored patterns of amphibian, water beetle, ant and fungal distribution and sampling seasonal pools and terrestrial surfaces of 13 representative plateaus in western Maharashtra, with sites ranging from 67-1179 m and across 2° of (sub) tropical latitude. Distribution of all taxonomic groups was spatially non-random at all levels of organisation and across all spatial scales. At the macroscale assemblages differed significantly with climate related to elevation, latitude but at a local scale land-use and microhabitat availably had an impact. Ants displayed a large seasonal assemblage variation, responding to seed availability. Water beetles the ants (combined survey data) were the best surrogates for all taxa data with amphibians the weakest representatives. Infection by the fungal pathogen, Batrachochytrium dendrobatidis, was extensive but less intense below the escarpment. We report the first records of infection in 13 endangered and data deficient amphibian species in the Western Ghats. The plateaus of western Maharashtra have recently been recognised as fragile and threatened ecosystems most still lack adequate statutory protection. In the absence of peer reviewed comparative data, the importance of individual sites is difficult to demonstrate hampering evidence-based conservation decisions.

Interações ente Bromelia balansae Mez e espécies lenhosas em áreas de ecótono floresta-afloramento rochoso

Camargo, Talita January 2011 (has links)
Interações positivas entre plantas têm sido demonstradas em várias comunidades em todo mundo, as quais desempenham papéis importantes na coexistência de espécies, produtividade e diversidade específica. Nesse estudo, avaliamos a influência de Bromelia balansae Mez sobre a riqueza específica, composição, abundância e diversidade de espécies lenhosas nos sub-bosques florestais e nas bordas externas de três afloramentos rochosos com cobertura herbácea presentes no Parque Estadual do Turvo, sul do Brasil. Estabelecemos 15 pares de unidades amostrais (u.a.) em cada afloramento rochoso e igual número na floresta, totalizando 180 u.a.. Consideramos as rosetas das bromélias como u.a. circulares e, como controle, instalamos u.a. correspondentes em áreas sem bromélias. Cada u.a. foi descrita pela abundância de indivíduos juvenis de espécies lenhosas. Para analisar o efeito de B. balansae sobre a riqueza, utilizamos curvas de rarefação baseados nas u.a.. Avaliamos também o efeito sobre a abundância de espécies no afloramento e na floresta utilizando ANOVAs com permutação. As curvas de rarefação revelaram uma diferença significativa da riqueza específica entre as u.a. nos afloramentos onde B. balansae está presente daquelas onde não está. Porém, na floresta, a riqueza de espécies entre u.a. com e sem B. balansae não apresentou diferença significativa. Nos campos rupestres, a presença de B. balansae influenciou positivamente a abundância de espécies em comparação às áreas controle. Na floresta, porém, não encontramos diferenças entre u.a. com e sem B. balansae. / Positive interactions among plants have been demonstrated in several communities around the world and play important roles in maintaining species coexistence, productivity and species diversity. In this study we evaluated the influence of Bromelia balansae Mez on species richness, composition, abundance and diversity of trees and shrubs in the forest understory and on the outer edge of rock outcrops present on Turvo State Park, Rio Grande do Sul, Brazil. The sampling was done in three outcrop areas, which constituted replicas, to evaluate the influence of the presence of B. balansae on woody species. To analyze the effect on the richness of bromeliads, we used rarefaction curves based on sampling units (s.u.). We also evaluated the effect on the abundance of species in outcrop and forest with ANOVAs using permutation. Rarefaction curves showed a significant difference in species richness between s.u. of the outcrops where B. balansae was present and the those without the species. However, the s.u. in the forest, species richness between s.u. with and without B. balansae showed no significant difference. In rocky fields, the presence of B. balansae has positively influenced the abundance of species in comparison to the control areas. In the forest, however, no differences between s.u. with and without B. balansae.
