Christo and Jeanne-Claude’s Running Fence, begun 1972 and installed in 1976, and Niki de St. Phalle’s Queen Califia’s Magical Circle, dedicated 2003, in northern and southern California respectively, reexamine the ways landscape art historically shaped ideological constructs, lived experience, and cultural economics. Christo, Jeanne-Claude, and St. Phalle draw on well known representations of the frontier and American West from the nineteenth century including, antebellum landscapes such as Thomas Cole’s The Oxbow, 1836 and Emmanuel Leutze’s Westward the Course of Empire, 1862 as well as Reconstruction Era landscapes including Andrew Russell’s The Golden Spike, 1869 and John Gast’s American Progress, 1872. When Christo, Jeanne-Claude, and St. Phalle’s West Coast art are viewed together, questions about history and tradition, the relationship of economics to cultural production, and aesthetics informed by place and environment, emerge as salient. Through the artists’ interest in time, place, and environment, as well as sustained engagement with community, Running Fence and Queen Califia’s Magical Circle construct representations of the local and interpret the histories and cultures of Sonoma and Marin Counties and Escondido. Running Fence and Queen Califia’s Magical Circle critically engage with artistic convention, state construction, capitalism and cultural production, and the construction of race, gender, and sexuality. As art historian William Truettner explained historical representations of the western frontier as “national pictures,” so too Running Fence and Queen Califia’s Magical Circle reinterpret historical images of the American West through an emphasis on community and place rather than nation-building and nationalism.

Emile Joseph Trognee's career took place not only during a time unsurpassed with regards to the musical and constructional developments of the trumpet, but also in the highly important and evolving musical environment of Imperial and Soviet Russia. As a result of an investigation of their inherent musical qualities, this document will establish how Emile Trognee's works are representative of European trumpet and cornet pedagogical and musical trends of the early 20th century. Through formal, thematic and harmonic analysis of these works, the key pedagogical and stylistic features are identified and discussed as consistent or unique to those of the period. Preceding that analysis and critical to an understanding of the contextual relevance of this material is a summation of the important 19th and early 20th century musical developments that influenced the instruction and use of the trumpet and cornet in Russia and Europe. It is hoped that modern study of the challenging works of that period will benefit from a better understanding of the performance and educational practices of those who were present at their inception or particularly adept in their performance.

Hurricanes are amongst the most devastating of the world’s natural disasters and can cause billions of dollars’ worth of damage every year. Efforts to predict where and when tropical cyclones might strike, then, could potentially save money and lives. A lack of data exists for the GA coast, and the future direction of climate change could potentially bring more hurricanes to the state. This study provides information to enhance the paleohurricane record by examining three vibracores drawn from St. Catherines Island, GA. After interpreting the environments that generated the sediment found in one of these cores and corroborating evidence from the additional cores, six potential hurricane events were discovered, five of which were likely major hurricanes, category 3 or higher. Magnitudes were determined by comparison to event six, thought to be “The Great Gale of 1804”, a major hurricane recorded by the sedimentary record of St. Catherines Island.

Climate change poses significant threats to mountain ecosystems in North America (Barnett et al., 2005) and will subsequently impact water supply for human and ecosystem use. To assess these threats, we must have an understanding of the local variability in hydrometeorological conditions over the mountains. This thesis describes the continued development and application of a fine scale spatial hydrometeorological model, GENESYS (GENerate Earth SYstems Science input). The GENESYS model successfully simulated daily snowpack values for a 10 year trial period and annual runoff volumes for a thirty year period. Based on the results of these simulations the model was applied to estimate potential changes in snowpack over the St. Mary River watershed, Montana. GCM derived future climate scenarios were applied, representing a range of emissions controls and applied to perturb the 1961-90 climate record using the “delta” downscaling technique. The effects of these changes in climate were assessed for thirty year time slices centered on 2020s, 2050s, and 2080s. The GENESYS simulations of future climate showed that mountain snowpack was highly vulnerable to changes in temperature and to a lesser degree precipitation. A seasonal shift to an earlier onset of spring melt and an increase in the ratio of rain to snow occurred under all climate change scenarios. Results of mean and maximum snowpack were more variable and appeared to be highly dependent on scenario selection. The results demonstrated that although annual volume of available water from snowpack may increase, the seasonal distribution of available water may be significantly altered. / viii, 93 leaves ; 29 cm

A binary clutter is cycling if its packing and covering linear program have integral optimal solutions for all Eulerian edge capacities. We prove that the clutter of odd st- walks of a signed graph is cycling if and only if it does not contain as a minor the clutter of odd circuits of K5 nor the clutter of lines of the Fano matroid. Corollaries of this result include, of many, the characterization for weakly bipartite signed graphs, packing two- commodity paths, packing T-joins with small |T|, a new result on covering odd circuits of a signed graph, as well as a new result on covering odd circuits and odd T-joins of a signed graft.

In 2005, the Government of St. Kitts and Nevis officially closed the sugar industry, ending mono-crop agriculture and opening a space for a new chosen economic driver, tourism. Newly available lands, an agricultural- based workforce and a push into tourism led to this research examining the state of agricultural tourism development in a transitioning region. Interviews with key public and private sector personnel, coupled with an evaluation of official policies and plans, were used in this qualitative case study to explore the state of agricultural tourism development (opportunities and barriers) and the role that stakeholders play in its creation. This research not only found common geographic and technical barriers but also endemic mental and behavioural characteristics of the local populace, which hinder agricultural development and, by extension, agricultural tourism. Negative attitudes towards agriculture and a lack of entrepreneurial spirit pervade, which hampers agricultural tourism development. Hence, this research shows that local attitudes towards agriculture play an important role in successfully diversifying agriculture via tourism. Many studies focus on the addition of tourism to an agricultural product without first ensuring the successful production of agricultural products themselves so that agricultural tourism can develop. Hence, this research asserts the need for the agricultural industry to upgrade its products to meet expected tourism standards before moving into agricultural tourism. Additionally, for the successful development of agricultural tourism, there needs to be a focused and sustained plan aimed at changing the mindset of the local populace towards agriculture and entrepreneurship, coupled with the government providing a facilitative environment conducive to developing agricultural tourism.

In the process of model-driven development (MDD) of software artifacts, domain-specific modeling languages (DSMLs) are an integral part. They act as the communication vehicle for aligning the requirements of the domain expert with the needs of the software engineer. With the rise of the UML as de facto standard for modeling software systems, MOF/UML-based DSMLs are now widely used for MDD. This paper documents design decisions from ten DSML projects which are based on the MOF/UML and which we conducted over the last years. We present our experiences in the form of reusable decision templates for all decision points detected in each phase of the DSML development process. Furthermore, we report also on identified decision dependencies which may occur within a single decision or between two decisions.

We have developed a regional mass balance model for the St. Lawrence River near Cornwall, Ontario that describes the fate and transport of mercury in three forms, elemental mercury (Hg0), divalent mercury (Hg2+), and methyl mercury (MeHg), in a five compartment environment (air, water, sediments, periphyton, and benthos). Our first objective was to construct a steady-state mass balance model to determine the dominant sources and sinks of mercury in this environment. Our second objective was to construct a dynamic mass balance model to predict and hindcast mercury concentrations in this environment. We compiled mercury concentrations, fluxes, and transformation rates from previous studies completed in this section of the river to develop the model in STELLA®. The inflow of mercury was the major source to this system, accounting for 0.42 mol month-1, or 95.5% of all mercury inputs, whereas outflow was 0.28 mol month-1, or 63.6% of all losses, and sediment deposition was 0.12 mol month-1, or 27.3% of all losses. The dynamic mass balance model provides estimated results that are consistent with measured data and predicts historical local industrial emissions to be approximately 400 kg year-1. Uncertainty estimates were greatest for advective fluxes in surface water, porewater, periphyton, and benthic invertebrates. This model is useful for predicting and hindcasting mercury concentrations in other aquatic environments because it contains the three main environmental compartments, all forms of mercury, and compartments (e.g. periphyton) not included in previous mercury multi-media models.

In the centuries that have passed since the premiere of Johann Sebastian Bach’s St. Matthew Passion in Leipzig’s St. Thomas’s Church at the Good Friday service in 1727, the work has had a remarkable performance history. Despite the fact that it received a number of repeat performances during Bach’s own lifetime (in revised versions), the St. Matthew Passion was largely forgotten after the composer’s passing until Felix Mendelssohn “resurrected” it in Berlin in 1829 with the localSing-Akademie and the Philharmonische Gesellschaft. The latter performance created such a level of excitement and interest in musical circles that two repeat performances followed soon after, despite Mendelssohn’s absence from Berlin. In 1970, Nikolaus Harnoncourt’s groundbreaking Telefunken LP of the St. Matthew Passion with the period instrument band Concentus Musicus Wien was released, a recording that, above all, stood in stark contrast to the consistent growth in the size of choirs performing this work that had occurred over centuries since Bach’s first performance in 1727. As with Mendelssohn’s performance, Harnoncourt’s interpretation generated great interest in scholarly circles and among the listening public. This critical commentary examines the size and constitution of the vocal and instrumental forces of all three performances of the St. Matthew Passion, as well as the extent to which those of 1829 and 1970 adhered to what is known of Bach’s own practices. In addition to investigating the choices made by the respective musical directors in this respect, the reception of Mendelssohn’s and Harnoncourt’s performances will also be considered.

The relationship between party organisation, class consciousness and workers’ struggle has been a basic issue in Marxism since its foundation, and particularly since the rise of revisionism at the end of the last century. To the very limited that a “mainstream” literature on Lenin sought to locate him within the Marxist tradition that tradition was identified with a determinist interpretation of Marx developed by the revisionists and centrists. This approach has been countered by a generally sympathetic view of Lenin’s comments on party organisation, argued by a recent set of “critics” of the “mainstream” view. Yet despite their wish to make a comprehensive critique of the “mainstream”, most of the critics have failed to do so due a residual element of determinism in their understanding of the relation between workers’ struggle and the development of class consciousness.This thesis seeks to complete the critique of the “mainstream” through establishing the role of conscious intervention in realising the material possibilities for workers’ struggle. It does so through a case study of the labour movement in St. Petersburg between the “Emancipation” of 1861 and the “Stolypin Coup” of 3/6/1907. A pivotal point in the development of this movement was “Bloody Sunday” (9/1/1905), and the thesis is structured around that moment to show what changes, as well as what does not change, in the role of conscious intervention in periods of mass struggle relative to times of more limited protest.
