  Citation × Citation Citation Abstract Copy Title: Gritos en el Desierto: Denuncia y Resistencia en las Obras de las Escritoras Wayuu Estercilia Simanca Pushaina y Vicenta Marí­a Siosi Pino Author: Perwak, Lindsay H. Year: 2016 The way we read and interpret literature is frequently influenced by factors that operate beyond the scope of the average reader's awareness. In this thesis, selected works by two Wayuu writers, Estercilia Simanca Pushaina and Vicenta Maria Siosi Pino, are analyzed and interpreted in an attempt to unveil some of these behind-the-scenes agents and issues, as well as explore how the stories' classification in the children's literature genre reveals a deep-rooted colonial tendency to infantilize indigenous individuals in contemporary Colombia. Despite the fact that the two authors, both mestizo women who self-identify with the Wayuu indigenous group of northern Colombia, prefer to write short stories that highlight the child and adolescent experience, the implicit themes and the complexity of their texts reject the "children's story" label that has been imposed on their literature. Furthermore, this thesis discusses how the two authors utilize the colonial trope of the Indian-as-child to their advantage by capsizing the imagery, thus rejecting the original power of the symbol and claiming it as their own. The first section of this investigation provides certain contextual specifics related to the cultural and social environment of the Wayuu indigenous group, particularly regarding that experienced by women. The second chapter includes an explanation of the impact a book's genre and its "paratext" may have on the reception and interpretation of these texts, and additionally proposes that the colonial practice of infantilizing indigenous people appears in both the assignment of genre as well as in several extratextual elements surrounding the stories. Chapter three offers an in-depth analysis of five selected pieces of the Wayuu authors' writing and explores how the texts may be read on multiple levels. This close reading reveals several examples of overt criticism towards the hegemonic society as well as displays instances of a more subtle rebellion; both explicit and implicit messages effectively expose and protest the current conditions of abuse, oppression and injustice that continue to anguish the Wayuu people.

  Citation × Citation Citation Abstract Copy Title: The Venus Victorieuse and Renoir’s treatment of the Female Nude Author: Yinger, Tess Year: 2010 Pierre-­‐Auguste Renoir’s sculpture Venus Victorieuse is a mythic image of the ‘ideal’ woman that was influenced by The Judgment of Paris, the Aphrodite of Knidos, and the imagery of Eve in the Garden of Eden. This work is fundamental to realizing Renoir’s overall treatment of the female nude, which is fully epitomized by this formal sculpture. Pierre-­‐Auguste Renoir was an Impressionist artist who dedicated the last three decades of his life primarily to the depiction of the female nude. His representation of the nude, both in painting and sculpture, was monumental and idealized, and he often created images of women that were mythic and evocative of the notion that woman belongs to the ‘natural sphere.’ Renoir’s sculpture, the Venus Victorieuse is an idealized and indeed mythic image that epitomizes the idea of woman as a seducer, animalistic by nature and inherently amoral. The first part of this essay will discuss the ways in which the Venus Victorieuse was influenced by two earlier works, The Judgment of Paris by Marcantonio Raimondi and Praxiteles’ Aphrodite of Knidos, and also how this image of Venus evokes the allegory of Eve and the notion of her ‘original sin’. Comparing the Venus with these two earlier works will address these influences and how they have informed the meaning behind Renoir’s sculptural interpretation of the mythic symbol of Venus. The second part of this essay will explore the ways in which Renoir has utilized the sculptural form to convey his ideas concerning the objectification of woman and the implications of her as inherently closer to nature, predisposed to sin and seduction.

  Citation × Citation Citation Abstract Copy Title: Molding the History of a Maritime Empire: The Role of the Thirteenth‐century Mosaics of San Marco in Reforming the Venetian Past Author: McCambly, Heather Year: 2013 The mosaics of the Venetian Church of San Marco embody how this empire used imagery for political and ecclesiastical purposes. The church of San Marco is recognized as a force which drew the island fragments of primitive Venice into a unified city and empire. This paper will examine the thirteenth-century mosaics by analyzing a variety of factors in the visual environment and the iconography of the mosaics themselves. First, I will examine briefly the nature medieval visuality and the previous architectural and artistic tradition within San Marco, moving then to analysis of the mosaics of the Old Testament cycle, the methods of transfer, and the model from which they were made. Next, I will explore the mosaics of the Cappella Zen and the South Transept as they pertain to the legend of Saint Mark. Last, I will present the historical context of the imagery in thirteenth-century Venice as well as the history of imitation and appropriation at San Marco. Finally, I will examine as a part of the historical context the medieval concept of time and history within the thirteenth-century environment, how it continues with and departs from prior traditions, and what this illustrates about the mosaics and the use of time and historical memory.

  Citation × Citation Citation Abstract Copy Title: Oregon Explorer : Natural resources information for current and future decision-makers Author: Salwasser, Janine, Wirth, Andrea A. Oregon Explorer (www.oregonexplorer.info), a natural resources digital library developed by Oregon State University Libraries and the Institute for Natural Resources, was created for Oregon’s natural resource decision-makers to promote informed and streamlined public and private decision-making. Examples of projects and successes of the Oregon Explorer include a basin portal for the Umpqua River, developed in conjunction with the Partnership for Umpqua Rivers, as well as topic portals, such as the Land Use Explorer launched in October 2007 to inform Oregonians about land use history and current issues. We have learned that in the natural resources arena, user needs change with different geographies, yet the adaptations made at the local level are useful in expanding the content and services delivered at the statewide level. It is not enough to just provide access to data or documents. Users want access to a wide variety of integrated information resources—digital documents, interactive maps and reports, decision support, high resolution imagery, and access to available expertise. With Oregon Explorer becoming established as a tool for decision-makers and citizens, members of the team are exploring opportunities to use the digital library in classroom settings. Students in Oregon’s K-12 schools and OSU’s undergraduates are groups that we feel could benefit from the natural resources information and tools available. Proposals are being developed to extend Oregon Explorer’s capabilities for use in primary and secondary education. Oregon Explorer is being used in several university classrooms and will become more integrated as the content and tools grow and as strategies for further incorporation are developed. This evolving natural resources digital library will enable current and future decision-makers to learn about Oregon's environment and to actively engage in creating and sharing knowledge before decisions are made.

  Citation × Citation Citation Abstract Copy Title: Western Juniper (Juniperus occidentalis) Ecology with an Exercise in Remote Sensing Techniques Author: Goralski, Elizabeth A. Year: 2008 Western juniper (Juniperus occidentalis var. occidentalis) has been expanding its biogeographic range since the mid-1800's, resulting in decreased biodiversity, altered wildlife habitat, increased soil erosion, reduced stream flows and reduced forage production. The direct causes of western juniper aforestation are unclear but appear to be related to altered fire regimes, over grazing, and climatic shifts. This study seeks to determine how Landsat images combined with Digital Orthoquads (DOQs) can be used to examine the geographic distribution of western juniper. Satellite imagery has yet to be applied to the large scale mapping of western juniper aforestation, resulting in the lack of regional and landscape level monitoring of western juniper range expansion. Remote sensing technologies, when combined with geographical information systems provide potentially valuable tools for monitoring western juniper expansion because of their abilities to assess large scale coverage of scenes, high cost effectiveness, and minimal field crew requirements. The two main objectives of my research are to review and summarize current literature regarding western juniper expansion and explore how remote sensing techniques may be used to quantify the expansion of the species. The results of my studies suggest that large patches of western juniper are detectable using Landsat imagery.

  Citation × Citation Citation Abstract Copy Title: Site formation at Ayia Varvara Asprokremnos and predictive modeling for neolithic sites, Cyprus Author: Barnett, Darby E. Site formation processes at Ayia Varvara Asprokremnos, a potentially early Neolithic archaeological site on Cyprus, are examined in order to build a larger predictive model. The study area immediate to the site encompasses 6.33 hectares and includes the site and alluvial terraces on both sides of the Gialias River. Fourteen soil map units, largely developed on Holocene colluvium, were identified. Stratigraphic profiles of the excavation trenches indicate a buried A horizon overlying what is thought to be a Pre-Pottery Neolithic B cultural component. Construction of a checkdam stopped site erosion and promoted the burial and preservation of a stratified archaeological sequence. The site is located next to a contact between the Lefkara Formation (limestone) and the Upper Pillow Basalts where vitreous chert commonly occurs on the island. Using the geoarchaeological data collected from Ayia Varvara Asprokremnos, satellite imagery and Geographic Information Systems data, a model was built the location of other further Neolithic Quarry sites on the island. The predictive model considers proximity to the contact, proximity to a 4th to 7th order stream, landscape position and relative level of ground disturbance. Over 38 areas were identified on 23 1:5,000 scale maps that could be explored by field survey and sub-surface testing.

  Citation × Citation Citation Abstract Copy Title: Multi-spatial scale representation of landscape transitions using landsat thematic mapper data and scale-space filters Author: Lindeman, Dale R. This thesis considered current approaches to describing landscape pattern, identified scale issues associated with defining objects, and explored techniques to reliably group elements based on land cover as represented by satellite imagery. It was recognized that there is an important need to develop tools that can be applied using remotely sensed data to objectively identify landscape features at multiple spatial scales. The thesis focused on the potential for the use of specific digital image processing techniques to objectively generate multi-scale landscape heterogeneity models from Landsat Thematic Mapper (TM) satellite imagery. An approach using Difference-of-Gaussian (DoG) scale-space filters was used to process TM satellite data, transformed into the Normalized Difference Vegetation Index (NDVI), to define discrete landscape units across a range of scales. A series of Difference-of-Gaussian filters, with standard deviation (a) pairs of 0.9 and 1.1, 0.8 and 1.2, and 0.7 and 1.3, was applied to TM data. Results were compared against published ecoregion classifications and aerial orthophotography. These comparisons showed that the applied filters failed to accurately define landscape elements at a range of spatial scales. Filter size was found to be highly sensitive to the resolution of the image and object boundaries were maldelineated when complex boundary combinations were encountered. A modified approach using Gaussian/Difference-of-Gaussian or GaussianlLaplacian filter combinations and an alternate approach of watershed segmentation were recommended as potential techniques to test in further study. Future study should also include statistical approaches to aggregate zones and relate delineated zones to an actual, on-the-ground physiognomic classification scheme.
