After the analysis we sought to understand the formation of the archaeological context and between the words to realize the process of modification of the space, realizing how this place was appropriate for individuals since the eighteenth century. / O estudo da Fonte da Carioca, na cidade de Goiás, teve como objetivo primeiramente a análise dos elementos arqueológicos com a pesquisa de campo e laboratório, onde abordaram-se conceitos teóricos vinculados ao estudo da cultura material. Posteriormente à análise buscou-se compreender a formação do contexto arqueológico e nas entrelinhas perceber o processo de modificação do espaço, percebendo a forma como este local foi apropriado pelos indivíduos desde o século XVIII.

nÃo hà / Na regiÃo do Cariri, no interior do Estado do CearÃ, vÃrias fontes de Ãgua nascem na Chapada do Araripe. Uma dessas, a Fonte Batateira, se converte no Rio Batateira, onde os produtores da cana-de-aÃÃcar desenvolveram em 1854 um sistema de direitos e alocaÃÃo de Ãgua baseado nas forÃas de Mercado de Ãguas. Esse modelo que ainda se encontra em operaÃÃo na atualidade permite a propriedade privada da Ãgua, bem como que respectivos proprietÃrios â possuidores de tÃtulos de direitos de uso da Ãgua - negociem referidos direitos, bem como, efetuem referidas transaÃÃes no CartÃrio PÃblico da Cidade do Crato. O mesmo nÃo ocorre no restante do Estado do Cearà e do Brasil que adota, na atualidade, o modelo de NegociaÃÃo (FrancÃs) que por sua vez reorganiza o ambiente institucional e define novos direitos de propriedade. Nessa perspectiva, e ainda considerando que o modelo adotado no Cariri-CE funciona hà mais de um sÃculo, ao final se visa concluir se ainda existe espaÃo legal institucional para continuar dentro de uma estrutura de mercado de direito de uso da Ãgua. Com esta pesquisa, busca-se contribuir com a gestÃo da Ãgua no Cariri haja vista que o presente momento de transiÃÃo à delicado e conflituoso, principalmente no aspecto da dominialidade do direito de uso da Ãgua. / In the area of Cariri, inside the State of CearÃ, several sources of water are born in the Araripe Plated. One of those, the Batateira fountain, turns into Batateira river, where the producing of the sugar-cane developed in 1854, a system of rights and allocation of water based on the forces of Market of Waters That model that still meets at the present time in operation it allows the private property of the water as well as that respective proprietorsâpossessors of titles of rights of use of the water - they negotiate referred rights, as well, make referred transactions in the Public Registry of the City of Crato. The same does not happen in the remaining of the State of Cearà and of Brazil that adopts, at the present time, the model of Negotiation (French) that reorganizes the institutional atmosphere for your time and it defines new property rights. In that perspective, and considering that the model adopted in Cariri - CE still works there is more than one century, at the end it is sought to conclude institutional legal space it still exists for Cariri - CE to continue inside of a structure of market of right of use of the water. With this research, it is looked for to contribute with the administration of the water in Cariri has seen that the present moment of transition is delicate and conflicting, mainly in the aspect of the dominium of the right of use of the water.

North Crater occupies the north-western quadrant of the Tongariro Volcanic Centre and represents one of at least eleven vents which have been active on Tongariro since the last glacial maximum. The most recent cone-forming activity at North Crater is thought to have occurred between 14-12 ka ago to produce the distinct, wide, flattopped andesite cone. This project focused mainly on the cone-building eruptions at North Crater, including stratigraphic correlations with distal tephra, interpreting eruptive processes, and establishing the sequence of events during cone construction. Detailed field work identified key stratigraphic sections and facies in the proximal, medial and distal environments. These sections allowed stratigraphic correlations to be made between proximal cone-building facies and distal sheet-forming facies at North Crater, and established a complete North Crater eruption stratigraphy. In the proximal environment, welded and non to poorly welded facies formed from fallout of a lava-fountain, pyroclastic flow or as fallout from a convecting plume. In the medial and distal environment, the lithofacies consist of fallout from a convecting plume and minor pyroclastic flow. Convective fall and non to poorly welded pyroclastic flow deposits dominate the lower eruption stratigraphy suggesting explosive eruptions involving a gas-rich magma. A change to welded deposits produced from lava-fountaining occurs later in the cone-building sequence and suggest a change to lower explosively and eruption of gas-poor magma. Grain size, componentry data, density, petrography and SEM analysis were carried out on representative samples to characterise the different facies, and reveal information about eruption processes. The non to poorly welded deposits are typically made up of vesicular pumice, scoria and mingled clasts of sub-rounded bombs and lapilli. The welded facies are relatively dense and clast outlines are often difficult to distinguish. The eruptives are porphyritic with abundant plagioclase gt clinopyroxene gt orthopyroxene gt opaques. Quartzofeldspathic crustal xenoliths are common and indicate crustal assimilation. Mingled clasts of light and dark glass were found to have microlites present in the dark glass, but were absent in the light glass. Electron microprobe analyses found that the dark and light glass components in a single clast had similar compositions, showing that the contrasting physical appearance of the glass is not due to a different chemical composition. Forty three whole rock XRF analyses showed that the magmas ranged from basaltic andesite to andesite, and Harker variation plots display linear trends typical of magma mixing. Magma mixing as the most important magmatic process is supported by disequilibrium of phenocryst compositions and phenocryst textures. Magma viscosity, bulk density and temperature was determined using MAGMA (Kware), and indicate that they fall into the range of typical andesites. Eruptive activity involved vigorous lava-fountaining, minor convecting eruption plumes and dominant collapsing eruption plumes. This activity has produced welded and non-welded pyroclastic flow and fall deposits to form the large cone seen today. There are significant volcanic hazards associated with this style of activity at North Crater, characterised by lava-fountaining, eruption plume fallout, and widespread pyroclastic flows and lahars extending beyond the ring plain. These could all be potentially devastating to the central North Island of New Zealand.

Cities are concentrations of diverse populations that undergo continual transformation over time. This thesis deals with the question, how does the individual make place in a constantly changing environment? The entry point for this study was looking at neglected places in urban environments. I looked specifically at the Don River Valley in Toronto, Ontario and how it has developed as an open-ended and complex system. The site research is presented through a series of stories describing specific events or places in the Don Valley that have taken place over the past 200 years. This thesis offers a mongrel approach to design for a site within the Don Valley. “The Mongrel Approach” is an opportunistic way of building that is committed to survival and open as to how this can be achieved. The design proposes a series of intimate yet public infrastructural devices; a toilet, water fountain, shelter and bridge that are presented in a set of hand drawings as well as through an “Explanatory Tale.” A magpie narrates this short story, which is part true, part fiction and part wishful thinking. As the earth’s population becomes more urban than rural and increasingly mobile, contemporary cities are becoming home to a diverse range of individuals with complex and layered identities. The Mongrel Approach offers a way of building that can handle difference and contradiction and accommodate incongruous or inharmonious parts. It positions the designer as a conjurer or first mover. This thesis proposes Mongrel buildings that respond to change by transforming slowly and incrementally over time with the involvement of multiple authors; but at each moment, a register of time and human ritual.

<p>Growing "old" in contemporary American society often means being seen as a problem: you threaten the stability of Social Security and Medicare; cutting-edge science seeks a cure for what ages you; cosmetic companies and health magazines sell you products and strategies for holding on to your youth as long as possible. <em>The Age of Obsolescence: Senescence and Scientific Rejuvenation in Twentieth Century America</em> traces the emergence of these attitudes toward old age back to the turn of the twentieth century when a publicly shared conception of aging was emerging in relation to advances in science and medicine, industrialized labor practices, a slowly developing welfare state, demographic observations of increased life expectancy, changing gender roles and expressions of national identity. During that time, the quest for the fountain of youth shifted from the stuff of legend to a driving motivation behind modern science.</p><p>In the four chapters of this dissertation, I bring literary critical methods to bear on literary and scientific texts, public health tracts, journalistic accounts, advertisements and public records. Through this survey of science, government and popular culture, I document the formation of several cultural narratives of aging--or, formulaic ways of addressing aging produced by repeated metaphors, imagery and story lines--that circulated with reciprocal influence through all of these spheres, determining attitudes toward, and experiences of, aging at that moment and into the present. After briefly exploring our contemporary "anti-aging" culture, the four chapters of <em>The Age of Obsolescence</em> address the framing of a moral responsibility for aging individuals to "take care of themselves" as a duty to their nation; the association of aging with obsolescence and its influence on worker's experiences and industrial practices; the scientific and cultural construction of aging as a disease in need of professional intervention; and the proposed "cure" for this problem of aging: scientific rejuvenation, particularly the glandular rejuvenation fad of the 1920s. My conclusion traces this fervor for scientific rejuvenation into the present, showing how the turn-of-the-century cultural logic of aging has become a taken-for-granted framework of American popular culture today. In illuminating the historical moment when the "problem" of aging was located in the bodies of aged individuals, I point toward solutions that may arise not from scientific discovery, but from rewriting these cultural narratives of aging and old age and restructuring the national practices that stem from them.</p> / Dissertation

To accommodate for human population growth along the Texas I-35 corridor, land is becoming increasingly urban and decreasingly pervious, modifying the infiltration and runoff rates in the Edwards Aquifer, especially to its spring fed Upper San Marcos River (USMR). Contaminants like heavy metals and organic chemicals can accumulate on impervious surfaces and with runoff, enter into the USMR at potentially harmful levels. The objective of this study was to determine how the population of an endangered Edwards Aquifer species, the fountain darter (Etheostoma fonticola), might respond to potential water quality changes associated with urbanization. I developed a stochastic, sex and stage-structured population dynamics simulation model that represents the relationships between urbanization, springflow variations, contamination levels, and natural history of the fountain darter. Future fountain darter population trends (2008-2040) were simulated under 10 treatments of nine scenarios. A simulation scenario (n=50) corresponded to one of three variations of springflow (random, high and low flow) and one of three variations in percentage of runoff entering the river (100, 50 or 30). The 10 treatments were variations on water quality: uncontaminated (1), contaminated by Cu (2), Zn (3), Cd (4), Cr (5), polycyclic aromatic hydrocarbons (PAH) (7), bifenthrin (8), carbaryl (9) and dicamba (10) and an additive affect of Cu, Cr, Cd, and Zn (6). Simulating ideal conditions, the average darter population from 2008-2040 was 54155+2969 (mean+SE) individuals. Contaminant treatments that caused a significant (p<0.001) decline in the population by 2040 under 100% runoff conditions were the all metal (650 plus/minus 640), Cu (3141 plus/minus 265), PAH (4621 plus/minus 475), Zn (6169 plus/minus 5406), and Cd (27987 plus/minus 6751) scenarios. With 50% runoff, the all metals (15740 plus/minus 5455), Cu (16815 plus/minus 6263), PAH (19675 plus/minus 995), and Zn (15585 plus/minus 3097) treatments simulated significantly lower populations (p less than 0.001). At 30% runoff, Cu (23976 plus/minus 6787), the all metal (25853 plus/minus 7404) and PAH (28167 plus/minus 1194) treatments decreased the population significantly (p less than 0.001). Over all scenarios, copper, zinc and PAHs caused >50% decline in the population. Assuming 100% or 50% of all San Marcos sub-basin runoff is directly entering USMR, there could currently be levels of Cu, Zn, and PAHs higher than what darters can withstand.

Lead exposure poses as a risk factor for various adverse health effects including intellectual delays, reduced IQ, and behavioural problems in children, as well as cognitive decline in adults. Lead enters drinking water through corrosion of leaded materials such as lead pipes, solder, and brass devices. Three rounds of residential and non-residential lead monitoring were conducted to evaluate the corrosion control implemented by Halifax Water, and to identify sites with elevated lead concentrations. Follow-up testing was conducted at several sites to determine the sources of lead, and the factors that contributed to high lead release. Finally, a bench scale experiment was conducted to determine the impacts of plumbing flux on metal release. The lead action level for residential testing was exceeded only in the round that was conducted during the winter. Lead concentrations were also higher in the winter rounds than the fall round of non-residential sampling. The seasonal lead variation was likely caused by fluctuations in aluminum residuals in the water leaving the plant. Frequency of use, age, and outlet manufacturer were factors that were associated with elevated lead levels. Follow-up studies were conducted at several fountains to determine the source of elevated lead levels. These fountains typically contained several leaded components and received infrequent use. Fountains with leaded components that received high, regular usage had often provided samples with low lead levels. Drinking fountains that were banned and recalled in the US for potentially containing lead lined cooling tanks were found at eight locations throughout the study area. It was found that three of the eight likely contained the lined cooling tanks. High lead levels were present in samples collected from these fountains, even at sites with frequent usage. Low-use sites with the lead lined tank produced the highest lead levels in this study. Fountains suspected of containing lead lined tanks were removed and replaced, and the lead levels were significantly reduced at these sites. The impact of plumbing flux on metal concentrations was relatively short in duration, lasting only a week for most metals, with the exception of tin. Lead levels were found to stabilize under all flux conditions following roughly 40 L of flushing. Flux type was the main factor contributing to the elevated metals. The traditional petroleum flux was much more resistant to flushing than the water soluble flux, as it caused elevated tin levels for several weeks and a tacky flux deposition in the copper pipe remained even three months after the start of the experiment. The high amount of chloride from the flux was aggressive towards the copper corrosion, but it is unclear if this would have led to copper pitting corrosion.

I conduct a series of experiments culminating in a gallery exhibition, I Never Stopped Being A Curator, which investigate and reinterpret what it means to ‘care’ and ‘profane’ in the context of an expanded notion of curatorial practice. I call what I’m doing ‘performative micro-curating,’ a playfully performative practice with precedents dating back to Marcel Duchamp and The Richard Mutt Case. More specifically, I’m interpreting and practising performative micro-curating as a relational, meta-conceptual art practice that uses mirroring and repetition as a method for posing questions, making knowledge and forging social bonds, while, at the same time, dissolving the boundaries that customarily distinguish artmaking from curating.

Parts of it have been referred to as the “Imperial Ghetto” (Badsha: 2001) or the “Duchene” and “Casbah” (Hassim: 2009) or simply “town” by the many who have frequented its markets, mosques, bus ranks, cinemas, schools, shops, cathedral and temples. The area is known for its “bunny-chows”, tearooms, saris, American Clothing stores, spices, jewellers, tailors, fah-fee and the feared Duchene gang. Central to the life of this “town” was Currie’s Fountain sports ground, popularly known as “Currie’s”, which served as a sports, cultural and political protest venue for seven decades. This urban experience of blacks, who were referred to as “non-Europeans”, during the apartheid era, and the institutions and places that are of cultural, educational, religious, sports and political importance, and thus part of the city’s heritage, is largely absent in publications on Durban’s history. This dissertation addresses this issue and focuses on an old part of Durban, referred to as the Warwick Junction Precinct (WJP), that was shaped by colonial and apartheid policies and planning, from the 1870s to the 1980s, identifying the “non-European” presence and what the nature of this presence was. It focuses on the micro level of the spatial development of a precinct, spawned in the aftermath of indenture and identifies the tapestry of facilities, institutions, places and spaces that collectively comprise and symbolise “non-European” Durban. It traces the establishment and growth of this other “invisible” precinct, since the settlement of Indians in Durban in the 1870s and the urbanization of Africans, until the 1980s when the apartheid ideology and its structures started to implode. Spatial information in the form of maps, diagrams and photographs, combined with the social history, laws and planning responses over a hundred and ten year period, identifies and maps out a substantial area that traces residential, religious, educational, commercial, sports and struggle sites that are of historical significance and thus part of the heritage of a multi-cultural city. Although restricted to a fairly small area, it has all the elements that comprise a city, such as commercial and residential areas, worship sites, a burial site, educational institutions and libraries, numerous markets, bus, train and taxi transport nodes, recreational and struggle sites that are of cultural and socio-political significance to Blacks in the city of Durban, for more than a century. This study documents the evolution of the Warwick Junction Precinct which has become a city in its own right with a rich heritage spanning both the colonial and apartheid eras. / Thesis (M.A.)-University of KwaZulu-Natal, Durban, 2012
