The lamppost: a metaphorical reflection on archival absences and presences

Khoza, Bongani 03 March 2016 (has links)
Dissertation in fulfilment of the degree of Master of Arts in Fine Arts by coursework and research report at the University of the Witwatersrand 2014 / My research intends to appropriate and recast Jacques Derrida’s ideas by seeking to interpret the written text as supplementary to photographic images. I use a close reading of Judith Coullie’s introductory text to Selves in Question: Interviews on Southern African Auto/biography (2006) to explore Santu Mofokeng’s representation of his biography and autobiography. Through selected works by Mofokeng, I highlight photographic ways and writing modes of expressing and locating his voice, drawing on the artist’s own subjective reality, memory and metaphor. The Truth and Reconciliation Commission (TRC) in conjunction with the introductory text to Selves in Question serve to provide much historical evidence and contexts to the complexities of writing a personal narrative in an exploration of freedom within the confines of oppression. I nevertheless acknowledge that some narratives are heavily dependent on a collaborative relationship. The negotiated different moments and perspectives that make up various presented narratives are born from spaces and places that act as intersections within the private and public in a constant state of stasis and movement..

Photography Distinguishes Itself: Law and the Emerging Profession of Photography in the Nineteenth-Century United States

Berger, Lynn January 2016 (has links)
This dissertation examines the role of the law in the development of photography in nineteenth century America, both as a technology and as a profession. My central thesis is that the social construction of technology and the definition of the photographic profession were interrelated processes, in which legislation and litigation were key factors: I investigate this thesis through three case studies that each deal with a (legal) controversy surrounding the new medium of photography in the second half of the nineteenth century. Section 1, “Peer Production” at Mid-Century, examines the role of another relatively new medium in the nineteenth century – the periodical press – in forming, defining, and sustaining a nation-wide community of photographers, a community of practice. It argues that photography was in some ways similar to what we would today recognize as a “peer produced” technology, and that the photographic trade press, which first emerged in the early 1850s, was instrumental in fostering knowledge sharing and open innovation among photographers. It also, from time to time, served as a site for activism, as I show in a case study of the organized resistance against James A. Cutting’s “bromide patent” (1854-1868). Section 2, Spirit Photography, Boundary-Work, and the Socio-Legal Shaping of Photography, focuses on the attempts of Oscar G. Mason and other photographers to get “spirit” photographer William H. Mumler behind bars for fraud and deception in 1869. Seeking to uphold the image of photography as a scientific, mechanically objective technology, and that of the photographer as an honest, trustworthy, and honorable professional, these photographers turned the courtroom into an arena for both the social construction of technology and for policing the boundaries of the photographic profession. Section 3, “Privacy, Copyright, and Photography in the United States, is about a question that photographers, publishers, courts and legislators spent much of the nineteenth century struggling to answer: who was the rightful author, and therefore owner, of a photograph? The Section details why that question arose when it did – in the final third of the nineteenth century – as well as the different ways in which photographers, their opponents, and representatives of the law struggled to define the nature of photography along with the meaning of photographic copyright. It also deals with the emergence, around the turn of the century, of a third party claiming ownership in the photograph – the sitter – and with how the “right to privacy” was formulated in part to accommodate that party. Finally, this third Section reveals the sometimes contradictory and often quite resourceful ways in which both the advocates and adversaries of photographic copyright enlisted the right to privacy in order to back up their own property claims, even when the nascent privacy right was meant to curtail the power of both these parties.

Galvão, Wiliam Carlos, 1977. January 2015 (has links)
Orientador: Zacarias Xavier de Barros / Banca: Bruna Soares Xavier de Barros / Banca: Paulo Roberto Arbex Silva / Banca: Adelson Francisco Maia Junior / Banca: Elvio Gilberto da Silva / Resumo: O processamento de imagens é uma área em crescimento. Diversos temas científicos são abordados e em alguns casos de caráter interdisciplinar. Entre eles pode-se citar: obtenção de imagens, compreensão de imagens, análise em multi-resolução e em multi-frequência, análise estatística, codificação e a transmissão de imagens. O conhecimento e a utilização dos recursos naturais, humanos e econômicos de uma região ou de um país, é de fundamental importância para o seu desenvolvimento. O planejamento do uso do solo tem se tornado cada vez mais importante diante desse contexto. Na agronomia mais precisamente no estudo de fotografias aéreas pode-se relacionar vários setores que poderão ser beneficiados por esse estudo, como por exemplo: levantamento e delimitação de bacias hidrográficas, geoprocessamento, fotogrametria, fotopedologia, fotointerpretação, mapeamento de solos, geoestatística e ocupação e uso do solo. Esse trabalho envolveu a linguagem de programação orientada a objetos JAVA e banco de dados relacional MYSQL ambos com licença gratuita e codigo livre, tornando possível o desenvolvimento de um sistema consistente, ganhando velocidade e confiabilidade na escrita dos códigos. Este trabalho teve como objetivo o desenvolvimento de um programa de computador para: processamento de imagens de fotografias aéreas, obtendose por meio de imagens bidimensionias imagens estéreoscopicas tridimensionais / Abstract: The image processing is a growing area.

The knowledge and use of natural resources, human and economic of a region or a country, it is of fundamental importance for its development. The planning of land use has become increasingly important in light of that context. In agronomy more precisely in the study of aerial photographs can relate various sectors that can benefit in this study, such as: survey and delineation of watersheds, GIS, photogrammetry, photo pedology, photo interpretation, soil mapping, geostatistics and occupation and use of ground. This work involved oriented programming language JAVA objects and relational database MySQL with both open source license, or free, making it possible to develop a consistent system, gaining speed and reliability in writing codes. This study aims to develop a computer program for: aerial photographs of image processing to get through two-dimensional images three-dimensional images / Doutor

Effect of photographs on shopping behavior of consumers

James Ravindran Santhakumar, Meetha Nesam January 1900 (has links)
Master of Science / Department of Food, Nutrition, Dietetics and Health / Delores Chambers / With increasing global e-commerce scenario, online shopping has become a part of our day-to-day life for products ranging from food to clothing and electronics. With globalization on one hand and tremendous change in the lifestyle of people, on the other hand, eating food outside of the home has also become an inevitable part of life nowadays. This study was designed to understand how photographs and information of the products influence the purchase behavior of consumers, to increase the purchase intent and liking of clothing sold online and food in a restaurant. The objectives of this study were to determine which type of photograph/description would have higher liking and purchase intent by consumers when they are shopping for clothes online and when ordering food in a restaurant. It also aimed to use different types of product descriptions to find any differences in overall liking, product perception, and purchase intent. An online survey was conducted with Indian women (n=600) through Qualtrics software. Data about demographics, overall liking, purchase intent and level of information gained based on the photographs were inquired for different type of photographic presentation of saris and Indian curries in two different sections. ANOVA, Correspondence Analysis (CA), frequency count analysis and descriptive statistics were employed for data analysis using XLSTAT software. In case of online shopping for clothing, especially saris, the results revealed that adding photographs of a model with/without a description to be a better presentation method as it acts as a virtual representation of the seller and is believed to establish trust between the consumers and the sellers. This thereby would lead to significantly higher overall liking, level of being informed and purchase intent. Similarly, in the case of restaurant shopping for food where the effect of photographs on a restaurant menu was studied, adding photographs of the food along with the sides with/without description was found to be a better presentation method. This was in turn related to significantly higher overall liking, level of being informed and purchase intent. Though there are no differences in the type of description added to the picture, adding information about the product was still found to be a critical factor for higher liking and purchase intent in both cases.

Modification of Karst Depressions by Urbanization in Pinellas County, Florida

Wilson, Kelly V 25 October 2004 (has links)
This thesis analyzes some of the effects of urbanization in Pinellas County, Florida on the karst landscape. Many sinkholes have been obscured and/or modified for storm water retention by urbanization in Pinellas County, with a few sinkholes still identifiable by characteristic zoning of vegetation, soil moisture, and circular shape. Using aerial photos from 1926 and 2000, karst features were identified by circularity,vegetation, and moisture conditions. Mapping karst surface features using historic aerial photos and maps is a useful exercise that will assist our scientific understanding of karstification in Florida and the nature and extent of karst processes that have acted in the pre-urbanized past. The final product of this research is a digital spatial database and metadata of karst features discernable on the 1926 and 2000 aerial photos; a description of the karst landscape mapped for each time period; and a morphometric description (including sinkhole area, density, and topography) of the karst landscape mapped for each time period. A total of 2,703 sinkholes were identified on the 1926 aerial photos. By 2000 only 900 sinkholes were still visible, a loss of 87.31%. Most of the loss of these sinkholes was due to the rapid urbanization that happened between 1926 and 2000. A total of 499 sinkholes that had been identified in 1926 have now been modified into storm water retention ponds.

Assessing Canopy Cover Requirements of Storm's Stork (Ciconia stormi) at Multiple Scales

Berdie, Ian Joseph 01 January 2008 (has links)
Much conservation work focuses on individual species, partly because of the perception that wildlife species are effective symbols for raising funds and drawing awareness to environmental causes. However, for species-based studies to aid conservation efforts, the biological and ecological needs of species need to be addressed in a way that informs decisions and provides concrete recommendations for land managers. This thesis addresses the forest cover needs of Ciconia stormi, a rare and understudied bird species that inhabits the islands of Borneo and Sumatra and parts of peninsular Malaysia. Levels of forest canopy cover associated with areas inhabited by Ciconia stormi are identified at multiple spatial resolutions using a 500m MODIS soft classification product, 30m Landsat data, and hemispherical photographs. Important threshold values of 75 percent tree cover was identified at the regional scale, and 85 percent at foraging sites. There has been severe forest disturbance in regions inhabited by Ciconia stormi between 1993 and 2004, indicating the species may be somewhat tolerant to disturbance. Areas having been logged at least 20 years before present average over 85 percent canopy cover and have few large gaps, indicating that these forests may be suitable habitat for the species.
