Description
This dissertation creates models of past potential vegetation in the Southern Levant during most of the Holocene, from the beginnings of farming through the rise of urbanized civilization (12 to 2.5 ka BP). The time scale encompasses the rise and collapse of the earliest agrarian civilizations in this region. The archaeological record suggests that increases in social complexity were linked to climatic episodes (e.g., favorable climatic conditions coincide with intervals of prosperity or marked social development such as the Neolithic Revolution ca. 11.5 ka BP, the Secondary Products Revolution ca. 6 ka BP, and the Middle Bronze Age ca. 4 ka BP). The opposite can be said about periods of climatic deterioration, when settled villages were abandoned as the inhabitants returned to nomadic or semi nomadic lifestyles (e.g., abandonment of the largest Neolithic farming towns after 8 ka BP and collapse of Bronze Age towns and cities after 3.5 ka BP during the Late Bronze Age). This study develops chronologically refined models of past vegetation from 12 to 2.5 ka BP, at 500 year intervals, using GIS, remote sensing and statistical modeling tools (MAXENT) that derive from species distribution modeling. Plants are sensitive to alterations in their environment and respond accordingly. Because of this, they are valuable indicators of landscape change. An extensive database of historical and field gathered observations was created. Using this database as well as environmental variables that include temperature and precipitation surfaces for the whole study period (also at 500 year intervals), the potential vegetation of the region was modeled. Through this means, a continuous chronology of potential vegetation of the Southern Levantwas built. The produced paleo-vegetation models generally agree with the proxy records. They indicate a gradual decline of forests and expansion of steppe and desert throughout the Holocene, interrupted briefly during the Mid Holocene (ca. 4 ka BP, Middle Bronze Age). They also suggest that during the Early Holocene, forest areas were extensive, spreading into the Northern Negev. The two remaining forested areas in the Northern and Southern Plateau Region in Jordan were also connected during this time. The models also show general agreement with the major cultural developments, with forested areas either expanding or remaining stable during prosperous periods (e.g., Pre Pottery Neolithic and Middle Bronze Age), and significantly contracting during moments of instability (e.g., Late Bronze Age).

Description
Meteorology is an uncommon term rarely resonating through elementary classrooms. However, it is a concept found in both fourth and sixth grade Arizona science standards. As issues involving the environment are becoming more pertinent, it is important to study and understand atmospheric processes along with fulfilling the standards for each grade level. This thesis project teaches the practical skills of weather map reading and weather forecasting through the creation and execution of an after school lesson with the aide of seven teen assistants.

Description
Plants are essential to human life. They release oxygen into the atmosphere for us to breathe. They also provide shelter, medicine, clothing, tools, and food. For many people, the food that is on their tables and in their supermarkets isn't given much thought. Where did it come from? What part of the plant is it? How does it relate to others in the plant kingdom? How do other cultures use this plant? The most many of us know about them is that they are at the supermarket when we need them for dinner (Nabhan, 2009) (Vileisis, 2008).

Description
Restraint stress is the most commonly used laboratory stressor. It is difficult to characterize as psychological or physical, because past studies show psychological features, but the nature of confinement adds a physical dimension. This was the first study to investigate how experience with restraint stress affects brain response to the next stress without a physical burden. Pair-housed adult male rats were transported to a novel context and restrained or left undisturbed (6hr). The next day, rats were returned to the same context and were either restrained or left undisturbed in the context (n=8/group). After 90min, rats were euthanized to determine functional activation in limbic structures using Fos immunohistochemistry and to measure HPA axis reactivity through blood serum corticosterone levels. Regardless of day 1 experience, context exposure on day 2 enhanced Fos expression in CA1 and CA3 of the hippocampus, basolateral amygdala, and central amygdala. Conversely, other regions and corticosterone levels demonstrated modulation from the previous day's experience. Specifically, rats that were placed back into the restraint context but not restrained on day 2 showed enhanced Fos expression in the dentate gyrus suprapyramidal blade (DGSup), and infralimbic cortex (IL). Also Fos expression was attenuated in rats that received two restraint exposures in the IL and medial amygdala (MEA), suggesting habituation. Only the DG infrapyramidal blade (DGInf) showed enhanced Fos expression to restraint on day 2 without influence of the previous day. While context predominately directed Fos activation, prior experience with restraint influenced Fos expression in the DGSup, IL, MEA and corticosterone levels to support restraint having psychological components.

Description
"Modernist Vintages" considers the significance of wine in a selection of modernist texts that includes Oscar Wilde's Salomé (1891), Dorothy Richardson's Honeycomb (1917), James Joyce's Ulysses (1922), and Evelyn Waugh's Brideshead Revisited: The Sacred and Profane Memories of Captain Charles Ryder (1945). The representations of wine in these fictions respond to the creative and destructive depictions of wine that have imbued the narratives of myth, religion, and philosophy for thousands of years; simultaneously, these works recreate and reflect on numerous wine-related events and movements that shaped European discourse in the nineteenth and twentieth centuries. The modernists use wine's conventional associations to diverse and innovative ends: as the playwright August Strindberg writes, "New forms have not been found for the new content, so that the new wine has burst the old bottles." Wine in these works alternately, and often concurrently, evokes themes that were important to the modernists, including notions of indulgence and waste, pleasure and addiction, experimentation and ritual, tradition and nostalgia, regional distinction and global expansion, wanton intoxication and artistic clarity. This project also discusses various nineteenth- and twentieth-century contexts that informed these works and that continue to shape our reading of them, including the propagation of restaurant culture; the development of a gastronomic literary tradition; the condemnation of alcohol by temperance strategists; the demarcation of wine as a "luxury good"; the professionalization and slow democratization of wine drinking and buying; the rise of popular, philosophical, and professional interest in the psychological and physiological effects of intoxication; and the influence of war on wine markets and popular attitudes toward wine. "Modernist Vintages" aims to demonstrate that the inclusion of objects like wine in modernist fiction is purposeful and meaningful, and thus inspires new and fruitful discussion about the works, writers, and nature of literary modernism in Europe.

Description
This dissertation considers the literary and cultural response of the labor-class poets to the emerging forces of Foucauldian biopolitics in early modern Britain to shed new light on the cultural impacts of biopower upon the rural community in early modern Britain. The analysis demonstrates how the labor class literary response is characterized by an exterior experience with the nonhuman in an alternative mode to the Wordsworthian experience of the interior. I then use labor-class poets to counter Wordsworthian notions of the immaterial State population through a critical expose of state-Subject, subject-object, and human nonhuman exterior relations as they are depicted in the labor-class poetry of late eighteenth and early nineteenth century Britain. Employing an object-ontological reading of community, I explore how the effects of biopower were inscribed in the literary artifacts of the labor-class. As a final consideration, I explore the response to postcolonial biopolitics in J.M. Coetzee's 1999 novel, Disgrace. The research takes a focused historical view, surveying a range of literary, political, and historical texts between 1760-1840 to offer new readings of Robert Bloomfield, Robert Burns, John Clare, William Cobbett, Ebenezer Elliott, Olivier Goldsmith, James Hogg, and William Wordsworth. In complement, the research offers a new reading of postcolonial biopolitics in the contemporary work of J.M Coetzee.

Description
Two critical limitations for hyperspatial imagery are higher imagery variances and large data sizes. Although object-based analyses with a multi-scale framework for diverse object sizes are the solution, more data sources and large amounts of testing at high costs are required. In this study, I used tree density segmentation as the key element of a three-level hierarchical vegetation framework for reducing those costs, and a three-step procedure was used to evaluate its effects. A two-step procedure, which involved environmental stratifications and the random walker algorithm, was used for tree density segmentation. I determined whether variation in tone and texture could be reduced within environmental strata, and whether tree density segmentations could be labeled by species associations. At the final level, two tree density segmentations were partitioned into smaller subsets using eCognition in order to label individual species or tree stands in two test areas of two tree densities, and the Z values of Moran's I were used to evaluate whether imagery objects have different mean values from near segmentations as a measure of segmentation accuracy. The two-step procedure was able to delineating tree density segments and label species types robustly, compared to previous hierarchical frameworks. However, eCognition was not able to produce detailed, reasonable image objects with optimal scale parameters for species labeling. This hierarchical vegetation framework is applicable for fine-scale, time-series vegetation mapping to develop baseline data for evaluating climate change impacts on vegetation at low cost using widely available data and a personal laptop.

Description
Land transformation under conditions of rapid urbanization has significantly altered the structure and functioning of Earth's systems. Land fragmentation, a characteristic of land transformation, is recognized as a primary driving force in the loss of biological diversity worldwide. However, little is known about its implications in complex urban settings where interaction with social dynamics is intense. This research asks: How do patterns of land cover and land fragmentation vary over time and space, and what are the socio-ecological drivers and consequences of land transformation in a rapidly growing city? Using Metropolitan Phoenix as a case study, the research links pattern and process relationships between land cover, land fragmentation, and socio-ecological systems in the region. It examines population growth, water provision and institutions as major drivers of land transformation, and the changes in bird biodiversity that result from land transformation. How to manage socio-ecological systems is one of the biggest challenges of moving towards sustainability. This research project provides a deeper understanding of how land transformation affects socio-ecological dynamics in an urban setting. It uses a series of indices to evaluate land cover and fragmentation patterns over the past twenty years, including land patch numbers, contagion, shapes, and diversities. It then generates empirical evidence on the linkages between land cover patterns and ecosystem properties by exploring the drivers and impacts of land cover change. An interdisciplinary approach that integrates social, ecological, and spatial analysis is applied in this research. Findings of the research provide a documented dataset that can help researchers study the relationship between human activities and biotic processes in an urban setting, and contribute to sustainable urban development.

Description
"The Hunger Games: What a Dystopic World Reveals about Modern Society" is an interdisciplinary thesis that examines the impossibility of revolutionary stories or concepts in popular culture by specifically analyzing the Hunger Games project. First, an analysis of what young adult fiction is and how it is written is provided. The formulaic way in which modern adolescent literature is written provides the basic structure for Suzanne Collins' Hunger Games trilogy. The second chapter examines the main character of the Hunger Games series, Katniss Everdeen. The way in which this young female heroine relinquishes her independence and courage due to being consistently undermined by the men and political leaders in her life is traced by following the development of the story throughout the three novels. The third chapter of the thesis delves into how the entire Hunger Games project of novels and films fits into current popular culture. An analysis of the mass production of the novels, and then turning the books into films, merchandise, and further commercialization of the story is discussed in detail throughout the chapter. Finally, the thesis discusses the responsibility authors of young adult literature should assume when addressing a young impressionable audience and how Collins took advantage of the position she had in telling the story of Katniss Everdeen.
