I have organized this paper into four chapters: "The Environmental Situation," "Space and Place," "Art and the Natural Environment," and "Creating Work of My Own." Chapter 1 explains human beings' intrinsic interconnection to the natural environment, outlining why humans should be concerned about the current degraded state of the natural world. Chapter 2 discusses the concepts of space and place. It analyzes how human beings interact with and experience spaces, developing their sense of place - within physical, theoretical, and spiritual realms. It finally illustrates the importance that spaces and places have in humans' lives. Chapter 3 describes the Land Art phenomenon: its development, the different forms within it, and artists producing Land Artworks. The forms and artists included are those that have been inspirational for the development of my own work. It also emphasizes Land Art as a fundamental form for improving humans' relationship with the natural environment and the new realm of eco-feminism that resonates with Land Art ideals. Chapter 4 recounts the development of my art throughout my college career. It describes my work as site-specific, sculptural installations that use natural materials. It also states why this format is the most effective for my senior art thesis project. Focusing mainly on "Ecological Reawakening: organic DNA," it explains the mentality in designing, creating, installing, and completing the work. Overall, Chapter 4 emphasizes the work's two main goals: to demonstrate a new avenue for comprehending humankind's place within earth's environmental spaces, and to advocate for an environmental paradigm shift during the twenty-first century. Finally, Chapter 5 describes the transformation of "Ecological Reawakening: organic DNA" as it developed over time during the spring honors senior thesis course. It details my mentalities in adding living plant matter to the structure, incorporating a stool into the piece, and creating "Evolution," the digital photography composition that documents "Ecological Reawakening" and was included in the Scripps Senior Art Exhibition in the Ruth Chandler Williamson Gallery from May 1 – May 17, 2009.

This study tested two hypotheses related to Woodland settlement trends and ritual development in East Central Indiana through the example of Mounds State Park in Anderson, Indiana. The first hypothesis was that earthwork enclosure complexes, such as at Anderson, were utilized as central places within a defined territory for the redistribution of resources. The second hypothesis was that a link existed between increasing social stratification in a mixed foraging and horticultural economy and a shift in the function of earthwork complexes resultant from a change in subsistence. It was determined that no conclusions could be made about the validity of these hypotheses due to incomplete data. Suggestions for obtaining relevant data and a theoretical model of earthwork function based on available data are presented. / Department of Anthropology

L’évolution actuelle du contexte socio-économique oblige les différents acteurs du secteur des travaux publics à s’adapter aux problématiques du développement durable. Dans le domaine des ouvrages en terre, les entreprises doivent proposer des solutions techniques de valorisation des matériaux situés dans l’emprise des projets afin de limiter les emprunts extérieurs et la mise en dépôt des sols non utilisés. Les techniques de traitement des sols constituent une possibilité de valoriser ces matériaux. Cette étude se focalise sur quatre produits de traitement (kaolinite, bentonite, chaux et ciment) ainsi que sur leurs effets sur le comportement hydromécanique et la résistance à l’érosion interne d’un limon fin. Un dispositif d’érosion interne HET optimisé a été spécialement conçu dans le cadre de ce travail pour déterminer les caractéristiques d’érosion des sols traités notamment à la chaux et au ciment. Au-delà de la caractérisation des effets du traitement sur le comportement hydromécanique à court terme des sols, le travail de cette étude s’étend sur la durabilité des traitements et l’évolution du comportent hydromécanique à long terme des sols traités soumis à des sollicitations hydriques de séchage-humidification. Cette étude de la durabilité est effectuée à travers une approche multi-échelle fondée sur des données d’études en laboratoire sur des éprouvettes de sol traité et des investigations in situ sur des ouvrages hydrauliques en sol traité. L’étude montre que les sollicitations hydriques peuvent dégrader les performances du sol traité. Cette dégradation se traduit par une augmentation de la conductivité hydraulique, une diminution de la résistance mécanique et aussi une diminution de la contrainte critique qui exprime une diminution de la résistance à l’érosion interne. La cinétique de perte de performances est conditionnée par la nature du produit de traitement et son dosage utilisé, et aussi par le niveau d’exposition, le nombre et l’intensité des cycles hydriques. Cependant, l’étude in situ montre qu’il est possible de diminuer la cinétique de dégradation des performances de sols à travers des dispositions constructives adaptées. / The current evolution of the social and economic context requires from the different actors of the public works sector to adapt their practices to the challenges of sustainable development. In the field of earthworks, companies must offer technical solutions to reuse the materials located in the vicinity of the projects in order to limit the borrowing materials and unused soils deposits. Soil treatment may allow the reuse of these materials. This study was focused on four treatment products (kaolinite, bentonite, lime and cement) as well as their effects on the hydro-mechanical behavior and internal erosion resistance of a fine silt. An enhanced HET device was designed in the framework of this study to determine the internal erosion characteristics of treated soils especially with lime and cement. Beyond the characterization of treatment effects on short-term hydro-mechanical behavior of soils, the work of this study extends to the durability of treatment and the evolution of long-term hydro-mechanical behavior of treated soils subjected to drying-wetting cycles. This study of sustainability was carried out through a multi-scale approach based on laboratory study data on soil samples and field investigations on hydraulic structures made of treated soil. The study showed that hydraulic conditions variations can decrease the performance of treated soils. These degradations result on an increase in hydraulic conductivity, a decrease of the mechanical strength and also a reduction in the critical shear stress which expresses a decrease of the internal erosion resistance. The kinetic of performance loss depends to the nature of the treatment product and percentage used as well as the exposure level, the number and amplitude of the hydraulic variations. However, the field study showed that it is possible to reduce the kinetic degradation of the soil performance through an appropriate construction design.

Répondre aux défis du développement durable exige la prise en considération des aspects économiques, sociétaux et environnementaux des projets. Dans le domaine des terrassements, les actions portent notamment sur l'optimisation de la valorisation des matériaux extraits grâce aux techniques de traitement des sols. Le projet s'est principalement porté sur les produits de traitement dérivant de la transformation de matières premières renouvelables : solutions « enzymatiques », lignosulfonates et solutions acides. Des données factuelles concernant les effets des traitements sur les caractéristiques hydromécaniques de quatre sols (un limon, un sol argileux et deux sables) ont été acquises mettant en évidence une augmentation de l'efficacité du compactage après traitement du limon au produit enzymatique et au lignosulfonate. La recherche des mécanismes d'action s'est fondée sur une étude de la microstructure par microscopie électronique à balayage et porosimétrie au mercure complétée par l'évaluation des effets d'un ajout de produits tensioactifs sur les propriétés des sols. L'objectif de l'étude dépasse cependant l'évaluation des modalités d'action des produits et vise également à prendre en compte les préoccupations environnementales. Ainsi, une étude d'analyse du cycle de vie a été menée pour chaque application ce qui a permis d'identifier les conditions optimales pour lesquelles les traitements combinent intérêts techniques et environnementaux. Ces conditions sont réunies lors du compactage des sols secs sous réserve que l'étape de production et de transport des produits ne soit pas excessivement pénalisante comme mis en évidence lors de l'étude de sensibilité / Sustainable development principles lead earthworks companies to use all natural materials and to reduce the environmental impact of their activities. In this context, the use of industrial organic products derived from the processing of renewable matter has been proposed. In this study, three non traditional products have been selected: an enzymatic solution, a lignosulfonate and an acid solution. In a first approach, hydromechanical properties of four treated soils (a silt, a clayey soil and two sands) were investigated. The experimental results showed interesting applications for the silt when its natural water content is low. Indeed, the compaction ability of the soil was increased after enzymatic and lignosulfonate treatments. Thus, savings of water and energy could be expected during the construction stage. To gain a better understanding of the mechanisms of the treatment products, the microstructure of treated soil were investigated with scanning electron microscopy, mercury injection porosity and was completed by the study of a surfactant addition in soils. The global aim of the study was beyond the characterization of mechanical behavior of treated soils, therefore, environmental balance was also estimated for the different applications defined in accordance to the experimental results. For enzymatic and lignosulfonate treatments, a comparison of the global environmental impact was done thanks to a life cycle assessment methodology. This approach showed that technical and environmental interest are associated for the compaction of dry soils when the production and transport steps have limited environmental impact as demonstrated in the sensitivity analysis
