I projektet har jag undersökt postindustriella miljöer på landsbygden, hållbar produktion och offentliga platser. Genom att undersöka och kartlägga bruksorten Stora Vika med dess industriområde försökte jag hitta och föreslå ett nytt sätt att återanvända det förfallna området. Genom att ta tillvara på förfallet på platsen, en naturlig process som möjliggörs av svampars egenskaper, och för att anspela på platsens industriella arv föreslår jag i projektet ett svampcenter kombinerat med ett hus för folket. De offentliga funktionerna som placeras på platsen tillgängliggör och öppnar upp det idag avstängda industriområdet, medan mitt tillägg i en befintlig struktur både erbjuder offentliga rum, producerar mycel som byggnadsmaterial, odlar svamp till restaurangen och möjliggör forskning på svampars möjligheter i en omställning till ett mer hållbart samhället. I projektet har jag undersökt postindustriella områden, modernismens ruiner och hur det är möjligt att återanvända befintliga byggnader. / The project focuses on how to deal with post industrial areas in a rural context, sustainable production and public spaces. By researching and documenting Stora Vika and its post industrial area i tried to find a new way of usage in the decayed place. To take advantage of the decay, which is possible because of fungus, and to connect to the industrial heritage I proposed a centre for fungus, combined with a house for the people. The public functions of the building will make the area itself more available, whilst the existing structure I am working within will serve for public usage as well as produce mycelium as construction material, mushrooms for the restaurant and a laboratory for research on fungus. In this project I have looked into post industrial areas, modern ruins and possibilities of reusing an existing structure.

Landscape planning is an approach to planning land use based on analysis of physical, biological, cultural, and aesthetic resources. Its aim is creative resolution of land use conflicts through the development of physical plans. These plans result from synthesis of scientific analyses produced by specialists from multiple disciplines and from reconciliation of the interests of different user groups. Landscape planning developed primarily as a specialty area within landscape architecture in the 1960s and 1970s. Its most recognized practitioner was Ian McHarg, author of the influential book Design With Nature (1969). Thirty years ago, landscape planners were on the cutting edge of environmental research. Their work led to methods for implementing the National Environmental Policy Act (NEPA) and the development of geographic information systems (GIS). Bridging the cultures of scientific research and professional planning practice was the aim of the first scholarly journal in the field, Landscape Planning, and it is a sentiment that characterized landscape planners quite well. In recent years, the profile of landscape planning has diminished considerably. Those who might have called themselves landscape planners in the past now identify themselves as ecological modelers, landscape ecologists, or environmental planners. Is it possible that the mission of classic landscape planning has been subsumed by these newer specialty areas? Or does landscape planning still have a role to play in the resolution of today's environmental and land use problems? These are the questions that this research addresses. To understand the evolution of landscape planning, its history is placed in context with the histories of city planning, ecology, and landscape architecture. To document the current status of the field, scholarly literature is analyzed through journal network analysis and content analysis of the last five years of landscape planning articles. This research sheds light on the complex relationships between disciplines engaged in environmental problem solving. Results suggest that there is still a need for landscape planning today, but that weaknesses must be overcome to make the field more effective. A new model of landscape planning is proposed to address the problems and yet still retain the strengths of the classic model.

Integrating the urban, the environment, and the public spheres in a modeling approach is an important goal for planners. Nevertheless, different terminologies, objectives, models, and the high complexity involved make it very uncommon. Modeling these different components is a challenge since it requires models that can integrate time and space dynamically, and incorporate complexity instead of dismissing it. This dissertation attempts to include these three spheres (urban, environment, public). It uses Cellular Automaton (CA) as the modeling environment, and the Lisbon Metropolitan Area (AML) and the Porto Metropolitan Area (AMP) as the areas of study. After introducing the subject of integrated studies and complexity, the area of CA is presented, and the organization of the dissertation is detailed. A second chapter describes the study areas. Chapters three, four, and five describe respectively the urban, the environmental landscape planning strategies, and the public inclusion. Chapter six interrelates the three components. The simulations that include the environmental, urban and expert's inputs develop scenarios that vary both visually and quantitatively. The simulation using the SLEUTH urban CA presents a trend scenario and demonstrates that by varying the pressures on the ecological (REN) and agricultural reserves (RAN) it is possible vary the urban pressures: relaxing RAN regulations decreases the number high probability of urban pressures, but spreads more areas of average pressures. The option for a limiting ‘no-growth’ strategy had similar results when including the sketch drawing from an expert workshop. The participant's concern with the urban image promoted a concentration of growth, an increase the number of cells with high probability of urban cells, but a reduction of the pressures of average probability urban cells. The countervailing model (CVCA) applied four landscape planning strategies in order to guide urban growth to more favorable areas that do not conflict with environmental land and the intensity of the urban pressures promoted more offensive urban pressures. Five main findings derive from the analysis of the results of each chapter: phase-transitions, existence of a “DNA” for each region, concepts of different images for the same Metropolitan Area, and the importance of integrating different models for metropolitan urban planning.

It is well known that city centers are fragile places and in constant change. The construction of new commercial developments on the periphery of cities greatly influenced the decline of city centers and of the more traditional forms of retailing there installed. The increasing awareness of this reality led different forms of government to act together with merchants to channel European Union funds to modernize traditional retailing enterprises and to revitalize shopping areas in city centers. This process led to the consideration that retailing is an important element in the livability of cities in Portugal. The commercial urbanism projects financed by the PROCOM Program created for the first time in Portugal a large debate about the importance of commercial planning and commercial revitalization of the city centers. The need to increase the private sector participation in this collective effort, as well as the need to find additional sustainable financing, besides the public subsidies, makes critical the call for proper answers to a more adequate and effective commercial revitalization of city centers. Given the fact that the commercial development on the outskirts of cities is not a unique Portuguese phenomenon, it is important and timely to reflect about foreign experiences in this area. The main objective of this dissertation is to discuss and analyze foreign experiences, mainly North American and British, in terms of commercial revitalization, the creation of public-private partnerships and city center management and present how they can relate to the Portuguese experience. The research methods involved literature reviews, comparative analyses, case studies, semi-structured interviews, meeting observations and a discussion of the implications for the Portuguese reality. The conclusion shows an updated knowledge of international best practices in terms of the creation and implementation of city center management partnerships. Finally, the recommendation section presents a set of proposals and principles that can be useful to Portuguese policy makers in the development and implementation of the second generation of commercial urbanism projects.

Page 214 Not included in thesis. / <p> Hydrothermal carbonate was introduced into igneous rock in the Timmins area during an early, sea water alteration event when calcite (δ13C = 0 to -3o/oo) filled the primary porosity of basalt flows and during a later hydrothermal event when mafic and ultramafic igneous rock were altered into a zoned sequence consisting of an inner zone of ferroan or magnesian carbonate flanked by calcite- and chlorite-rich assemblages. The younger intense carbonate alteration event predated or was synchronous with regional metamorphism and deformation and was focused along structurally induced, permeable zones. Gold was introduced during and after the intense carbonate alteration.</p> <p> Away from carbonaceous sediments, δ13C-values of the ferroan carbonate are very uniform (-3.5 to -5o/oo) regardless of stratigraphic position, size, or gold tenor of the alteration zone. As carbonaceous sediments are approached, 13C of the ferroan carbonate becomes upto 4o/oo heavier. The 13C of the CO2 and δ18O and δD of the water components of the hydrothermal fluid are estimated to have been -3 to -6, +5 to +10, and -40 to -60o/oo respectively. The geological controls on the distribution of carbonate alteration, and the stable isotopic values of the hydrothermal components suggest that the H2O-CO2 hydrothermal fluid was of magmatic origin, a result of mantle degassing.</p> / Thesis / Doctor of Philosophy (PhD)

The purpose of this research is to determine how Geographic Information Systems (GISs) can be modified for more efficient use in land use planning and design. While information-oriented GIS technology has proven useful for routine and administrative aspects of planning and design, it is not yet capable of providing information and knowledge interactively within a problem solving process that can be characterized as "ill-structured." This suggests that GIS technology must be embedded within a larger problem solving process of planning and design. The hypothesis of this research is that implementation of conceptualization-oriented Spatial Decision Support Systems (SDSSs) will significantly improve the use of GIS technology for ill-structured land use planning and design problems. A residential design problem is introduced as a prototypical ill-structured application for the SDSS model. Drawing on this application, several new ideas are described in terms of human information processing: "Bubble-centered Design Support Systems" as an extension of short-term memory, "Prototypes" as an extension of semantic memory, and "Scripts" as an extension of episodic memory. For the future implementation of these ideas, some important SDSS functions, such as linked views and multiple representations, are described. Finally, discussions of the novel approach provide direction for future GIS technology in ill-structured planning and design process.

The traditional travel demand modeling process is designed to develop relationships among travel characteristics, land use activities, and a simulated transportation system network. The models are calibrated to base year conditions through comparisons of theoretical travel patterns, trip length characteristics, and traffic volumes with similar observed values. For projections of travel to future time periods, the assumption is made that the established database and relationships, and in particular the traffic analysis zones to which these data are assigned, will be the same for the forecast period as at the time of calibration. The primary objective of this research was to establish criteria for decision-making regarding which zones should be subdivided and to develop a technique for deciding how to subdivide. The eventual goal of the research was to improve travel demand forecasts. This research investigated whether travel demand estimates can be improved through the reconfiguration of traffic analysis zones for the future year projection period and through an associated restructuring of the centroid connectors for the future network. Similar subarea techniques have been applied by others in attempts to develop more accurate traffic data for project-specific needs. The subarea approach suffices for project needs, but the adjustments and modifications are not usually fed back into the modeling process. Therefore, the time and effort expended in obtaining project data are not applied to the improvement of the overall travel demand forecasts on a study-wide or regional basis. Under these conditions, system planning efforts and corridor analyses do not receive the benefit of updated information or system refinements. The findings of this research indicate that there is little improvement in the travel forecasts as a result of the subdivision of 9 zones in the New Castle County model into a total of 23 new units. Link-by-link comparisons of traffic assignments based on the New Castle County original 228 zone system and the modified 242 zone system reveal no significant improvements. One reason that can be identified is the detail of the simulated roadway system, which nearly duplicates the existing street and highway network and leaves little opportunity to provide alternative travel routings resulting from the creation of small traffic analysis zones.
