The objective of this paper is to develop a well-defined and sound framework for the implementation of a multi-participant GIS program and to illustrate the developed framework by its application to the Departments of the Town of Blacksburg. A multi-participant approach to implementing GIS technology faces greater challenges than a single-participant GIS project, due to the unique culture, structure, policy, decision-making rule and expectations of participants from implementation of GIS technology. So a successful program depends upon aligning different characteristics of the program's structure to those of participants, individually and collectively. Maximizing the system's potentials necessitates a well-defined implementation framework that can help manage changes and integrate the technology in organizations. Therefore, the paper focuses on the implementation aspects of multi-participant GIS programs. The paper achieves its objective by exploring various issues involved in the implementation process of GIS technology and multi-participant GIS programs, develops a framework for implementing a multi-participant GIS program and applies the framework to the Departments of the Town of Blacksburg to achieve successful implementation. The illustration of the Town of Blacksburg identifies various constraints for multi-participant GIS program for which recommendations are provided to achieve successful implementation.<br>Master of Urban and Regional Planning

We can classify several quite different calculi for automated reasoning in first-order logic as instantiation-based methods (IMs). Broadly speaking, unlike in traditional calculi such as resolution where the first-order satisfiability problem is tackled by deriving logical conclusions, IMs attempt to reduce the first-order satisfiability problem to propositional satisfiability by intelligently instantiating clauses. The Inst-Gen-Eq method is an instantiation-based calculus which is complete for first-order clause logic modulo equality. Its distinctive feature is that it combines first-order reasoning with efficient ground satisfiability checking, which is delegated in a modular way to any state-of-the-art ground solver for satisfiability modulo theories (SMT). The first-order reasoning modulo equality employs a superposition-style calculus which generates the instances needed by the ground solver to refine a model of a ground abstraction or to witness unsatisfiability. The thesis addresses the main issue in the Inst-Gen-Eq method, namely efficient extraction of instances, while providing powerful redundancy elimination techniques. To that end we introduce a novel labelled unit superposition calculus with sets, AND/OR trees and ordered binary decision diagrams (OBDDs) as labels. The different label structures permit redundancy elimination each to a different extent. We prove completeness of redundancy elimination from labels and further integrate simplification inferences based on term rewriting. All presented approaches, in particular the three labelled calculi are implemented in the iProver-Eq system and evaluated on standard benchmark problems.

A Component Oriented Software Engineering (COSE) modeling environment is enhanced with the capability to import executable components and deliver applications through their composition. For this purpose, an interface layer that utilizes JAR libraries as components has been developed. Also, Domain Engineering process has been applied to Geographical Information Systems (GIS) domain and utilized towards converting the environment to a development framework. The interface layer imports JAR libraries into the COSECASE tool, which is a graphical tool supporting COSE approach and COSE Modeling Language (COSEML). As a result, systems can be designed using abstractions and then implemented by corresponding deployed components. Imported code is made available to the COSECASE environment through this interface layer. Also, Domain Analysis, Domain Design, and Domain Implementation phases of Domain Engineering process have been applied to the GIS domain. Components developed in this Domain Implementation phase have been imported into COSECASE. A simple GIS application has been designed and generated through the interface layer of COSECASE for demonstration purposes.

Geographic information is one of the most important and the most common types of information in human society. It is estimated that more than 70% of all information in the world has some kind of geographic features. In the era of information explosion, information retrieval (IR) tools, such as search engines, are the main tools people used to quickly find the information they need nowadays. Because of the importance of geographic information, recent efforts have been made either by expanding the traditional IR to support a spatial query, or building a GIR in a brand new architecture from the ground such as the SPIRIT project. To some degree, these existing GIR systems could solve users’ information search need with a spatial filter, especially when the users are looking for information on something within a relatively large extent.Despite its advantage on processing geographical information and queries over conventional IR systems, modern GIR systems are also facing challenges including a proper representation and extraction of geographical information within documents, a better information retrieval model for both thematic and geographical information, a fast indexing mechanism for rapid search within documents by thematic and geographical hints, and even a new architecture of system.The objective of this licentiate research is to provide solutions to some of these problems in order to build a better modern GIR system in the future. The following aspects have been investigated in the thesis: a generic conceptual framework and related key technologies for a modern GIR system, a new information retrieval model and algorithm for measuring the relevance scores between documents and queries in GIR, and finally a new better indexing technique to geographically and thematically index the documents for a faster query processing within modern GIR.Concerning the proposed conceptual framework for modern GIR, it includes three modules: (1) the user interface module, (2) the information extractor, storage and indexer module and (3) the query processing and information retrieval module. Two knowledge bases, Gazetteer and Thesaurus, play an important role in the proposed framework. A digital map based user interface is proposed for the input of user information search needs and representation of retrieval results. Key techniques required for the implementation of a modern GIR using the proposed framework are a proper representation of document and query information, a better geographical information extractor, an innovative information retrieval model and relevance ranking algorithm, and a combined indexing mechanism for both geographical and thematic information.The new information retrieval model is established based on a Spatial Bayesian Network consisting of place names appeared in a single document and the spatial relationships between them. The new model assesses the geographical relevance between GIR document and query by the geographical importance and adjacency of the document geo-footprint versus the geographical scope of the user’s query.Regarding the indexing mechanism for modern GIR systems, a Keyword-Spatial Hybrid Index (KSHI) is proposed for the single and overall geo-footprint model, in which there is only one single geo-footprint for each document to retrieve from. A Keyword-Spatial Dual Index (KSDI) is proved to be more appropriate for a GIR system which allows for multiple geo-footprints within a single document.In addition to theoretical analysis, necessary experiments have also been carried out to evaluate the efficiency of proposed new information retrieval model and indices. Both the theoretical analysis and results of experiments show the potentials of proposed solution and techniques.<br>QC 20110630

Nature Refuges encompass the second largest extent of protected area estate in Queensland. Major problems exist in the data capture, map presentation, data quality and integrity of these boundaries. The spatial accuracies/inaccuracies of the Nature Refuge administrative boundaries directly influence the ability to preserve valuable ecosystems by challenging negative environmental impacts on these properties. This research work is about supporting the Nature Refuge Programs efforts to secure Queensland’s natural and cultural values on private land by utilising GIS and its advanced functionalities. The research design organizes and enters Queensland’s Nature Refuge boundaries into a spatial environment. Survey quality data collection techniques such as the Global Positioning Systems (GPS) are investigated to capture Nature Refuge boundary information. Using the concepts of map communication GIS Cartography is utilised for the protected area plan design. New spatial datasets are generated facilitating the effectiveness of investigative data analysis. The geodatabase model developed by this study adds rich GIS behaviour providing the capability to store, query, and manipulate geographic information. It provides the ability to leverage data relationships and enforces topological integrity creating savings in customization and productivity. The final phase of the research design incorporates the advanced functions of ArcGIS. These functions facilitate building spatial system models. The geodatabase and process models developed by this research can be easily modified and the data relating to mining can be replaced by other negative environmental impacts affecting the Nature Refuges. Results of the research are presented as graphs and maps providing visual evidence supporting the usefulness of GIS as means for capturing, visualising and enhancing spatial quality and integrity of Nature Refuge boundaries.

Doctor of Philosophy<br>Department of Curriculum and Instruction<br>Jacqueline D. Spears<br>Scientists agree that there is ample evidence of climate change and that a significant portion of the change is anthropogenically driven. Leiserowitz et al. (2011b) asked teenagers about their understanding of the climate system and the causes of climate change. Fewer than 20% of respondents classified themselves as “very well informed” and only 27% reported that they learned “a lot” about climate change in school. However, of these teenagers, 70% expressed a desire for more climate change education. Even though the idea of human impacts on the climate system and a changing climate have been known and discussed within science education for several decades, dedicating classroom time for teaching climate change is not a common practice. Focus group discussions with science and agricultural education teachers (Pytlikzillig et al., 2013) emphasized the need for the use of locally relevant data in the classroom as a means to engage students in critical thinking activities that require them to use and draw conclusions from these data. However, most teachers do not have access to such data or a working knowledge of technological platforms from which they can have the students observe, manipulate, and analyze these data. This study used a mixed methods research design to explore the use of a GIS-based framework for teaching climate change. A two-part intervention was used: 1) teacher training, and 2) classroom implementation. Student-, teacher-, and classroom-centered data were collected to address student outcomes, teacher perceptions of GIS use in teaching climate change, and both students’ and teachers’ perceptions of challenges and successes of using GIS in the classroom. Students showed an overall positive growth in knowledge. Teachers shared a positive perception regarding the use of GIS to teach climate change, going so far as to report that they will all continue to teach climate change and use GIS in their classrooms. Successes and challenges were observed in classrooms, recognizing the benefits of student engagement and learning, as well as the challenges of using technology and supporting student needs. This exploratory research supports the premise that using a GIS-based framework to teach climate change is practical, reproducible, and effective.

Ingeniero Civil en Computación<br>Casi al final de la cadena de administración de la información geográfica en las organizaciones, se encuentra la tarea de la publicación. Para la automatización de dicha tarea, existe en el mercado una amplia variedad de software GIS, dentro de la cual destaca la oferta de ESRI. Sin embargo, los costos de implementar una solución como la ofrecida por ESRI no pueden ser asumidos por pequeñas y medianas organizaciones. De esta situación se hace cargo este trabajo. Este trabajo consistió en la construcción de un marco de desarrollo base para publicar información geográfica, el cual consta de dos elementos principales: * Un conjunto de librerías que extienden un framework de desarrollo web, para el trabajo con objetos geográficamente referenciados. * Una aplicación web, construida sobre la base del framework extendido, para generar y administrar Aplicaciones Web de Mapas. El resultado obtenido, basados en tecnologías gratuitas y de código abierto, fue validado a partir de la implementación de un caso de uso, consistente en la creación y extensión de una Aplicación Web de Mapas en un dominio específico. Se concluye que el trabajo realizado permitirá a las organizaciones de menor tamaño publicar la información geográfica de la que disponen de manera controlada, y se plantean finalmente algunas recomendaciones sobre cómo seguir extendiendo las funcionalidades del marco de desarrollo base.

Uncertainty in geospatial data fusion is a major concern for scientists because society is increasing its use of geospatial technology and generalization is inherent to geographic representations. Limited research exists on the quality of results that come from the fusion of geographic data, yet there is extensive literature on uncertainty in cartography, GIS, and geospatial data. The uncertainties exist and are difficult to understand because data are overlaid which have different scopes, times, classes, accuracies, and precisions. There is a need for a set of tools that can manage uncertainty and incorporate it into the overlay process. This research explores uncertainty in spatial data, GIS and GIScience via three papers. The first paper introduces a framework for classifying and modeling error-bands in a GIS. Paper two tests GIS usersâ ability to estimate spatial confidence intervals and the third paper looks at the practical application of a set of tools for incorporating uncertainty into overlays. The results from this research indicate that it is hard for people to agree on an error-band classification based on their interpretation of metadata. However, people are good estimators of data quality and uncertainty if they follow a systematic approach and use their average estimate to define spatial confidence intervals. The framework and the toolset presented in this dissertation have the potential to alter how people interpret and use geospatial data. The hope is that the results from this paper prompt inquiry and question the reliability of all simple overlays. Many situations exist in which this research has relevance, making the framework, the tools, and the methods important to a wide variety of disciplines that use spatial analysis and GIS.<br>Ph. D.

Throughout history floods have been part of the human experience. They are recurring phenomena that form a necessary and enduring feature of all river basin and lowland coastal systems. In an average year, they benefit millions of people who depend on them. In the more developed countries, major floods can be the largest cause of economic losses from natural disasters, and are also a major cause of disaster-related deaths in the less developed countries. Flood disaster mitigation research was conducted to determine how remotely sensed data can effectively be used to produce accurate flood plain maps (FPMs), and to identify/quantify the sources of error associated with such data. Differences were analyzed between flood maps produced by an automated remote sensing analysis tailored to the available satellite remote sensing datasets (rFPM), the 100-year flooded areas "predicted" by the Flood Insurance Rate Maps, and FPMs based on DEM and hydrological data (aFPM). Landuse/landcover was also examined to determine its influence on rFPM errors. These errors were identified and the results were integrated in a GIS to minimize landuse / landcover effects. Two substantial flood events were analyzed. These events were selected because of their similar characteristics (i.e., the existence of FIRM or Q3 data; flood data which included flood peaks, rating curves, and flood profiles; and DEM and remote sensing imagery.) Automatic feature extraction was determined to be an important component for successful flood analysis. A process network, in conjunction with domain specific information, was used to map raw remotely sensed data onto a representation that is more compatible with a GIS data model. From a practical point of view, rFPM provides a way to automatically match existing data models to the type of remote sensing data available for each event under investigation. Overall, results showed how remote sensing could contribute to the complex problem of flood management by providing an efficient way to revise the National Flood Insurance Program maps.

This project developed a new method to address sustainability aspects relevant to the location of biomass energy plants. The method is based on an integrated geographical information system model to identify optimal sites for biomass energy supply, incorporating spatial biomass availability, and economic, environmental and biomass specific uncertainties in the biomass supply chain. The analysis was carried out in Queensland, Australia as a case study, demonstrating the potential of multiple biomass sources for biomass energy supply.

Magister Artium - MA<br>The trend in metropolitan planning is to provide overarching objectives for development, leaving detailed interpretation at the local level. The unspecific nature of these guidelines, however, coupled by the parochial interests of constituent local municipalities, can result in development that is unfavourable in terms of the metropolitan vision. The aim of this research was to consider a more detailed basis according to which the metropolitan plan for the Cape Metropolitan Area, the Metropolitan Spatial Development Framework (MSDF), could possibly be promoted. The approach was to focus on vacant land since this will be the target of future development.

Recent technological advances have resulted in increasingly larger databases. The fast and efficient useful analysis and interpretation of this data to improve business intelligence is critical to the success of all organisations. This thesis presents a new framework that utilises a new multilayer mining theory and is based on business intelligence methods, data mining techniques, online analytical processing (OLAP) and online transactional processing (OLTP). Existing decision making modelling approaches for executive information systems have three main shortcomings and limitations to different degrees: a) problems in accessing new types and new structures of data sources; b) failing to provide organizational insight and panorama; and c) generating excessive amount of trivial information. The hypothesis of this research is that a new proactive Multidimensional Multilayer Mining Management Model (5M) framework which is proposed in this thesis will overcome the shortcomings listed above. The 5M framework is made up of 6 components: (a) multilayer mining structures; (b) measurable objectives conversion models; (c) operational transaction databases; d) object-model data marts; (e) data cubes and (f) core analysis engine which analyse the multidimensional cubes, multilayer mining structures and the enterprise key performance indicators. The 5M framework was evaluated by developing an implementation of an instance of the framework called the Ebusiness Analytical Framework (EBAF). The 5M framework and the subsequent EBAF framework were built by carrying out action research and a case study in an ebusiness company where it was subject to implementation, reflection, adaptation and improvement in order to fulfil the requirements of the hypothesis and that of a real business. EBAF implemented all 6 components of the 5M framework using the Visual Studio environment and using various algorithms, tools and programming languages. The programming languages used included MDX, DMX, SQL, VB.Net and C#. Further empirical case studies can be carried out to evaluate the effectiveness and efficiency of the 5M framework.

The paper emphasises the importance of a research programme focused on developing and making widely available GIS relevant spatial analysis technology. It outlines generic criteria able to discriminate between GIS-relevant and GIS-irrelevant spatial analysis tools and outlines a list of six researchable spatial analysis themes. It is argued that presently there is an opportunity to develop a EU based spatial analysis research programme and then install the technology in the World's GIS.

Cette thèse présente un nouveau cadre pour la conception de correcteurs à gain programmé. Une partie de ce cadre est une fusion novatrice de la théorie des systèmes et de la commande (la métrique ν-gap et sa variante fréquentiellle) et de l'analyse en grappes, technique commune en analyse de données statistiques, apprentissage automatique, fouille de données, etc. La combinaison des deux champs permet de subdiviser le domaine de fonctionnement d'un système non linéaire en secteurs afin de récupérer des informations sur le comportement en boucle fermée avant la conception de la commande. Chaque secteur représente une partie du domaine opérationnel ayant des propriétés de retour similaires, c'est-à-dire que les points de fonctionnement dans un secteur ont des comportements davantage similaires (mesurés par la mesure d'écart ponctuel) les uns des autres que les points de fonctionnement des autres secteurs. La solution de sectorisation est utilisée en vue de réaliser des correcteurs séquencés réglés à partir d'un modèle linéarisé. Par exemple, une distribution optimisée et parcimonieuse des points de synthèse pour les correcteurs LTI est sélectionnée et la distribution des secteurs est exploitée pour le mélange des correcteurs linéaires individuels en un correcteur non-linéaire couvrant l'ensemble du domaine de fonctionnement. L'avantage général de ce cadre est qu'il présente une procédure systématique qui réduit potentiellement le temps, les efforts et donc le coût global d'un projet de développement en réduisant les itérations inutiles au cours du cycle de conception. Le cadre proposé est évalué à partir d’un exemple générique de missile industriel<br>This thesis presents a new framework for the design of gain-scheduled controllers. Part of this framework is a novel merging of system &amp; control theory (the ν-gap and pointwise gap metric) and cluster analysis, a common technique in statistical data analysis, machine learning, data mining, etc. The combination of both fields allows for a subdivision of a nonlinear system's operating domain into sectors in order to retrieve information on the feedback behaviour before the actual control design. Each sector represents a part of the operating domain with similar feedback properties, i.e. operating points inside a sector are more similar (as measured by the pointwise gap metric) to each other than to operating points in other sectors. The sectoring solution is used in the proposed framework to support the design of a linearization-based gain-scheduled controller. For example, a reduced and optimized distribution of design points for the LTI controllers is selected and the sectors' distribution is exploited for the blending of the individual linear controllers into an operating domain wide nonlinear controller. The overall advantage of the framework is that it presents a systematic procedure that potentially reduces the overall time, effort, and therefore cost of a development project by preventing unnecessary iterations in the design cycle specifically associated with the control design. The proposed framework is verified at the example of a generic industrial missile benchmark

Dans le contexte actuel de démocratisation des technologies et des méthodes géomatiques, les expériences du type « Public Participation GIS » - PPGIS se multiplient. Le concept de PPGIS est, par essence-même, interdisciplinaire et multiforme. Il s’apparente, d’une certaine façon, à un déclinaison spécifique des SIG, vus comme des systèmes d’information (données, matériels, logiciels, méthodes et composantes humaines), incluant la dimension de la participation publique. De fait, les PPGIS ne se limitent pas aux simples outils logiciels. L’objectif principal d’un PPGIS consiste à accentuer/supporter l'implication des citoyens dans les processus de prise de décisions territoriaux, et à améliorer l'accès aux outils, aux données ainsi qu’à l'information (Steinmann et. al. 2004). Les applications des PPGIS revêtent des formes très variées, selon le contexte économique, l’organisation sociale et politique, la culture, mais également en fonction des problématiques traitées et des méthodologies développées (Joliveau 2006). Les exemples mettent en évidence qu’en pratique, la dimension ‘participation publique’ des PPGIS renvoie à des réalités différentes. La construction du domaine des PPGISciences (Sieber 2004) est basée sur la convergence de concepts sociaux, culturels, éthiques et environnementaux avec les technologies de l’information et à la géomatique. Ce développement engendre des questions épistémologiques complexes, dans la mesure ou chaque discipline impliquée pose évidemment un regard différencié sur les PPGIS. Par conséquent, le concept même de PPGIS est ambigu. Il n'existe pas de consensus sur ses éléments caractéristiques. Ce constat pose problème, tant sur le plan scientifique que sur le plan pratique, dans la mesure où il rend difficile, non seulement la formalisation de méthodes de développement adaptées aux PPGIS ; mais aussi le développement de critères d'évaluation de succès et d'échec (Craig et al. 1999). La communauté scientifique des PPGIS considère d’ailleurs que pour comprendre la réalité sur laquelle les chercheurs doivent appuyer leurs travaux, la formalisation consensuelle d’une définition claire et précise du concept de PPGIS s’impose. Les spécialistes affirment que l’une des priorités actuelles est la conception d’un cadre théorique basé en particulier sur une typologie des PPGIS (Tulloch 2003, Steinmann et al. 2004). Malgré les quelques recherches déjà réalisées, seules quelques typologies partielles ont été développées, et le concept demeure flou. L’objectif principal de cette recherche consiste à concevoir une typologie plus globale à partir d’une analyse en profondeur des concepts sous-jacents. Sur le plan plus pratique, cette recherche vise à concevoir et à développer un observatoire web des expériences PPGIS (ce dernier étant à la fois une composante de l’objectif et un moyen de l’atteindre). La méthodologie est basée sur la construction d’un cadre théorique (analyse de la littérature et des typologies existantes) et une analyse empirique (étude d’une série d’expériences de PPGIS). La méthodologie est complétée par une enquête sur les forums web spécialisés, de manière à solliciter la communauté du domaine et à valider nos résultats. Cette recherche a ainsi permis de construire une typologie des PPGIS, plus globale, complémentaire de celles déjà existantes. Se faisant notre travail permet d’améliorer la compréhension de ce domaine en émergence et apporte des éléments formels permettant de mieux le caractériser.<br>Dans le contexte actuel de démocratisation des technologies et des méthodes géomatiques, les expériences du type « Public Participation GIS » - PPGIS se multiplient.

The concept of PPGIS is, by its nature, interdisciplinary and multiform. It is connected, in a certain manner, to a specific variation of the GIS, understood as information systems (data, hardware, software, methods and human factor), including the dimension of public participation. Essentially, PPGIS are not limited to simple software tools. The principal objective of a PPGIS consists of accentuating/supporting the implication of the citizens in the territorial decision making processes, and to improve the access to tools, data, and information (Steinmann et al. 2004). Applications for PPGIS take a variety of forms depending on the economic context, the social and political organization, the culture, but also regarding to the treated problems and developed methodologies (Joliveau 2006). Examples underline that, in practice, dimension of “public participation” in PPGIS echoes different realities. The creation of the field (Sieber 2004) is based on the convergence of social concepts as well as cultural, ethical and environmental concepts associated with information technologies (IT) and Geomatics. This development generates complex epistemological questions, in a measure where each implied discipline obviously poses a different view on PPGIS. Consequently, the concept of PPGIS is ambiguous. There is no consensus on its characteristic elements. This circumstance causes some problems, both on the scientific and practical levels. It makes difficult, not having the standardization of methods of development adapted to the PPGIS; but also the development of evaluation criterions of success and failure (Craig and al 1999). Besides, the scientific community associated with PPGIS considers that in order to understand reality that the researchers must rely on their works, the agreed formalization of a clear and precise definition of the concept of PPGIS is inevitable. Specialists affirm that one of the current priorities is to design a theoretical framework particularly based on a typology of PPGIS (Tulloch 2003, Steinmann et al. 2004). In spite of some research work already carried out, only a few limited typologies were developed, and the concept remains unclear. The principal objective of this research consists of conceiving a more global typology starting from an in-depth analysis of the subjacent concepts. From a practical level, this research aims at designing and developing a web-based observatory of PPGIS experiments (this one is a component of our objective and at the same time a means of reaching it). Our methodology is based on the construction of a theoretical framework (literature review and an analysis of existing typologies) and an empirical analysis (study of a series of PPGIS experiments). Methodology is effectuated by an investigation into the specialized Web forums, so as to solicit the community of the field and to validate our results. This research thus made it possible to build a typology of the PPGIS, as a hole, complementary to those already existing. Doing this work improves understanding of this field in its infancy and elicits formal elements for better characterization of PPGIS.<br>In the current context of democratization of technologies and methods of geomatics, “Public Participation GIS” practices - PPGIS multiply.

This development generates complex epistemological questions, in a measure where each implied discipline obviously poses a different view on PPGIS. Consequently, the concept of PPGIS is ambiguous. There is no consensus on its characteristic elements. This circumstance causes some problems, both on the scientific and practical levels. It makes difficult, not having the standardization of methods of development adapted to the PPGIS; but also the development of evaluation criterions of success and failure (Craig and al 1999). Besides, the scientific community associated with PPGIS considers that in order to understand reality that the researchers must rely on their works, the agreed formalization of a clear and precise definition of the concept of PPGIS is inevitable. Specialists affirm that one of the current priorities is to design a theoretical framework particularly based on a typology of PPGIS (Tulloch 2003, Steinmann et al. 2004). In spite of some research work already carried out, only a few limited typologies were developed, and the concept remains unclear. The principal objective of this research consists of conceiving a more global typology starting from an in-depth analysis of the subjacent concepts. From a practical level, this research aims at designing and developing a web-based observatory of PPGIS experiments (this one is a component of our objective and at the same time a means of reaching it). Our methodology is based on the construction of a theoretical framework (literature review and an analysis of existing typologies) and an empirical analysis (study of a series of PPGIS experiments). Methodology is effectuated by an investigation into the specialized Web forums, so as to solicit the community of the field and to validate our results. This research thus made it possible to build a typology of the PPGIS, as a hole, complementary to those already existing. Doing this work improves understanding of this field in its infancy and elicits formal elements for better characterization of PPGIS.

The decision-making process of transport projects is very complex, especially for public administrations which have to take into account often incomparable criteria of judgment. In addition, in order to achieve a good social sharing and robustness of the decision, policy makers have to include in the process not only the transport planning experts but also the stakeholders of the community. The purpose of this study is to propose an evaluation framework that supports the decision making process able to allow public participation in the assessment of transport design scenarios while at the same time ensuring a high level of technical quality of the final decision. The framework will include a method to analyze monetary and non-monetary parameters that will be easily understandable for all decision makers. It will be based on the application of Multi Criteria Decision Analysis (MCDA) techniques, an evaluation process that can take into account different quantitative and qualitative objectives and criteria; in order to favor public participation, the implementation of this technique will take advantage of Geographic Information System (GIS) for its ability to easily represent the impact of spatially based alternative project scenarios. Different case studies will be analyzed in order to assess the level of implementation of the three main ingredients of the framework: Multi Criteria Analysis, GIS and Public Participation.

The target for carbon dioxide (CO2) emissions reduction in the UK is set at 20% by 2020 and 80% by 2050. The UK housing stock is one of the least energy efficient in Europe. The energy used in homes accounts for more than a quarter of energy use and carbon dioxide emissions in Great Britain. Therefore, it is imperative to improve the energy performance of the existing housing stock and fully exploit energy efficiency and renewable energy interventions. Several tools have been developed particularly in the last decade for energy assessment of dwellings, largely to inform policy development. However, when it comes to policy implementation stages, stakeholders such as local councils, energy suppliers, social housing providers and planners lack an effective tool, which assists them in estimating the potential for energy performance improvement through implementation of energy efficiency and renewable energy interventions. The UK government has several policies and initiatives to improve the energy performance of the housing stock. This research discusses the development of framework and a prototype tool to assist in implementation of these policies. There are a number of databases that hold information about the condition of the housing stock. This is in the form of digital maps, aerial and terrestrial imagery and statistics from census and housing surveys. This research presents an innovative way of integrating this information to undertake energy performance assessment on various geographical levels. The framework and the prototype allow stakeholders to determine the baseline energy performance of the dwellings based on their existing characteristics. This information is then used to estimate the potential for reduction in energy consumption and CO2 emissions and associated costs. Also integrated within the framework and the prototype is analytical hierarchy process based multi-criteria decision analysis technique that supports stakeholders in selection of energy performance improvement interventions suited to their requirements. Energy Performance Improvement of Dwellings Abstract Amit Mhalas, 2013 iv The developed framework and prototype are calibrated and validated with empirical data to determine the accuracy, reliability and trustworthiness. To demonstrate the practical applicability of the framework and the prototype, two separate case studies are undertaken involving the stakeholders. The results from the case studies indicate a potential to reduce CO2 emissions from dwellings by 70% through installation of energy performance improvement interventions. The developed framework and the prototype are expected to assist stakeholders in making informed decisions with regard to the implementation of energy policies and initiatives and contribute to meeting CO2 emission reduction targets.

This research proposes a new site analysis methodology in the form of an integrated framework. The framework separates the site analysis process into different models, incorporates each model, and considers the interaction between them. The most important models are the environmental models (climate, geology, hydrology, topography, and vegetation models), social-cultural models, economic models, and infrastructure models. Each model also contains several important factors. The study identifies and organizes environmental factors within the framework that influence site analysis and design. Based on the applicability of feng shui principles and their interpretations into measurable factors, this research compares and incorporates feng shui and contemporary environmental design theories, and summarizes essential environmental factors. The emphasis on environmental factors from these models may lead to a better understanding of the relationships between humankind and the natural environment. The proposed framework is implemented into a computer simulation program, titled SiteOne, to demonstrate the concepts and ideas, with an emphasis on environmental factors. This research uses the town of Reston in Fairfax County, Virginia, as the study area because of the availability of information. SiteOne analyzes a range of alternatives and then derives solutions from the suggested site conditions in the form of GIS maps. There are various modules that make up the prototype system: namely an analysis module, a database module, and a result generation module. SiteOne helps professionals collect a wide range of information and select corresponding criteria in the early stages of design. It also provides visual analysis based on selected criteria and models. Therefore, it can act as an educational knowledge component for professionals as well as the general public.<br>Ph. D.

Visualization could be defined as the graphical presentation of information, in which the main aim is to improve the user&rsquo<br>s perception. In all phases of the disaster management, decision makers come across huge data sets with spatio-temporal content. It is hard to deal with these sets in order to find answers to the main question of &ldquo<br>How can we decrease the losses due to disasters?&rdquo<br>, which is at the core of the disaster management concept. To furnish this aim, disaster risk information has to be transparent and clearly stated to the public, decision makers and disaster managers. This might be more sophisticated than the calculation of the risk. Taking precautions before a disaster to reduce the causalities and lossess engendered by natural disasters is relatively cheaper, and more importantly, better than cure. To achieve enhanced preparations for all kinds of disasters, visualization is quite an important tool for decision support and risk communication. The basic aim of this research is to propose a conceptual framework, with the consideration of all stakeholders related to the disaster management issue to have a better risk communication, and to guide the design, implementation and integration of the 3D urban modeling tools into disaster risk visualization. Moreover, an empirical methodology is also developed for the generation of visualization solutions through the design, and employment of the tool for disaster management framework. The proposed framework has three main phases .These are the definition of visualization components, object representation, and needs assessment. A new LoD hierarchy with indoor is proposed to visualize all the possible 3D urban disaster situations in the first phase. Then, a decision rule with eight attributes is proposed in the second phase to establish a link between the hazard type and the LoD needed in a 3D urban model for visualization. This decision rule is applied in a proposed three-level hierarchycal structure. The assessed objects of these three levels are urban, sub-urban zone and building. Moreover, a method to define the needed sub-urban zone is proposed. Finally, different 3D urban modelling methods are analyzed to define the data and process needs of possible 3D urban disaster visualization situations. Two natural hazard cases are studied within the scope of this dissertation to assess the operability of the proposed framework. These implementations involve one earthquake and one tsunami case. Special attention is paid to finding one specific sample for two modelling viewpoints, namely static and dynamic. The first applications of the proposed framework with all the related features prove quite promising.

Thesis (MBA)--Stellenbosch University, 2003.<br>ENGLISH ABSTRACT: When hedging with futures contracts the hedge ratio is one of the fundamental figures needed to set up a successful hedging strategy. The Mean Variance framework has been used for some time to calculate hedge ratios for this exact purpose. Certain assumptions are implicit in the Mean Variance framework such as the assumed normality of returns and assumed quadratic utility functions of investors. The validity of these assumptions has been questioned in the literature. The Mean Gini framework is first and second order stochastically dominant implying that there is no assumption regarding the return process or the utility function of investors. This study compares these two frameworks regarding the hedge ratios generated by each and their subsequent hedging effectiveness. The results indicate that neither one of the two frameworks generate the most effective hedge ratios all the time. The Mean Gini framework is, however, preferred above the Mean Variance framework for a significant number of futures contracts evaluated. It can therefore be concluded that making use of the Mean Variance framework for all futures contracts would have resulted in numerous ineffective hedging situations.<br>AFRIKAANSE OPSOMMING: Wanneer verskansing met termynkontrakte gedoen word is, die verskansingsverhouding een van die fundamentele veranderlikes waaroor 'n besluit geneem moet word. Vir 'n geruime tyd word die Minimum Variansie verskansingsverhouding vir hierdie doel gebruik. Implisiet in die Minimum Variansie raamwerk is die aannames dat opbrengste normaal verdeel is en dat die beleggersnutsfunksie kwadraties van aard is. Die geldigheid van hierdie aannames het reeds heelwat kritiek in die literatuur ontlok. Die Gemiddelde Gini raamwerk is eerste en tweede graads stochasties dominant, wat impliseer dat geen aannames aangaande die opbrengs of die beleggersnutsfunksie gemaak word nie. Die studie vergelyk beide raamwerke rakende die verskansingsverhoudings deur elk gegenereer en die gepaardgaande verskansingdoeltreffendheid. Die resultate toon dat nie een van die twee raamwerke vir alle kontrakte die mees effektiewe verskansingsverhouding genereer nie. Die Gemiddelde Gini raamwerk word egter vir 'n beduidende aantal van die termynkontrakte bestudeer bo die Minimum Variansie raamwerk verkies.

Nutrient inputs into the environment greatly impact urban ecosystems. Appropriate management strategies are needed to limit eutrophication of surface water bodies and contamination of groundwater. In many existing urban environments, retrofits or complete upgrades are needed for stormwater and/or wastewater infrastructure to manage nutrients. However, sustainable urban nutrient management requires comprehensive baseline data that is often not available. A Framework for Urban Nutrient (FUN) Management for Geographic Information Systems (GIS) was developed to specifically address those areas with limited data access. Using spatial analysis in GIS, it links water quality, land use, and socio-demographics, thereby reducing data collection and field-based surveying efforts. It also presents preliminary results in a visually accessible format, potentially improving how data is shared and discussed amongst diverse stakeholders. This framework was applied to two case studies, one in Orange County Florida and one in Placencia, Belize. A stormwater pond index (SPI) was developed to evaluate 961 residential wet ponds in Orange County, Florida where data was available for land use and socio-demographic parameters, but limited for water quality. The SPI consisted of three categories (recreation, aesthetics, education) with a total of 13 indicators and provided a way to score the cultural and ecosystem services of 41 ponds based on available data. Using only three indicators (presence of a fence, Dissolved Oxygen (DO) < 4 mg/l, and water depth < 3 ft), 371 out of 961 stormwater ponds were assessed. Additional criteria based on socio-demographic information (distance to a school, population density, median household income under $50,000, percentage of population below the poverty line, and distance to parks) identified seven wet ponds as optimum for potential intervention to benefit residents and urban nutrient management purposes. For the second case study, a water quality analysis and impact assessment was performed for the Placencia peninsula and lagoon in Belize. This study had access to water quality data, but limited land use data and very limited socio-demographic data. Since May 2014, water quality samples have been taken from 56 locations and analyzed monthly. For this study, Dissolved Oxygen (DO), Nitrate (NO3--N), Ammonia (NH3), Chemical Oxygen Demand (COD), and 5-Day Biochemical Oxygen Demand (BOD5), Escherichia coli (E. coli), and Enterococci were selected to assess spatial and temporal variation of water quality in the groundwater on the peninsula as well as the surface water in lagoon, estuaries and along the coast. A spline interpolation of DO, Nitrate, BOD5, and COD for June 2016 indicated the concentration distribution of those parameters and areas of special concern. A spatial analysis was conducted that showed that Nitrate and Enterococci exceeded the effluent limits of Belize very frequently in the complete study area while the other parameters contributed to the identification of key areas of concern. As a high variability of concentrations over time was observed, a temporal analysis was conducted identifying a link between the water quality data and two temporal impact factors, rainfall and tourism. The two case studies showed the broad and flexible application of the FUN management for GIS and the great advantages the use of GIS offers to reduce costs and resources use.

This thesis describes the creation and possible uses of a Geographical Information System that contains the changing boundaries of the major administrative units of England and Wales from 1840 to 1974. For over 150 years the census, the General Register Office, and others have used these units to publish a wealth of data concerning the population of the country. The key issue addressed by the thesis is that changes in the administrative geography have hampered much research on long-term change in society that could have been done using these sources. The goal of the thesis is the creation of framework to allow the analysis of long-term socio-economic change that makes maximum use of the available data. This involves not only making use of the data's attribute (statistical) component, but also their spatial and temporal components. In order to do this, the thesis provides solutions to two key problems: the first is how to build a GIS containing administrative units that incorporates an accurate record of their changing boundaries and can be linked to statistical data in a flexible manner. The second is how to remove the impact of boundary changes when comparing datasets published at different dates. This is done by devising a methodology for interpolating data from the administrative units they were published using, onto a single target geography. An evaluation of the accuracy of this interpolation is performed and examples are given of how this type of research could be conducted. Taken together, these will release information locked up within historical socio-economic statistics by allowing space to be explicitly incorporated into any explorations of the data. This, in turn, allows research to explore the past with increased levels of both spatial and attribute data for longer time periods.

This thesis concentrates on the development of a prototype Decision Support Framework based on the landscape epidemiology concept and using GIS to determine human health risk in Semarang (Indonesia). This site was selected as representative of a rapidly urbanizing area in a developing country. The decision support framework examines climatic, landscape and socio-economic factors identified as having significant impacts on water quality and subsequent causation of waterborne and water-related diseases. The research outcomes potentially may be applied worldwide to identify and isolate areas most vulnerable to the effects of the mentioned diseases thus improving quality of life in developing countries.

Efter att EU införde ett ramverk år 2000 rörande regionens vattenanvändning, vattendirektivet, beslöt Sveriges regering att från och med sommaren 2020 ompröva rikets vattendammar. I de fall rådande vattenanvändning inte uppfyller de krav som anges i ramverket kan dammutrivning bli aktuellt. Syftet med studien är undersöka och utveckla en metod att utvärdera förändringar av strömhabitat uppströms ett vattendrag efter en dammutrivning. Studieområdet utgörs och begränsas av datamängden i form av flygfoton insamlade med UAV vid två tillfällen över samma område. Även batymetriska data över vattendragets botten från en bottenskanning har använts således även Lantmäteriets nationella höjdmodell. Två fotogrammetriprogram användes i arbetet, dels för att skapa en ortomosaik från flygfoton men även för att utföra en bildnormalisering. GIS programvaran ArcGIS Pro tillhandahåller flera algoritmer för klassificering av raster. Algoritmerna SVM och RT, viktades mot varandra och SVM användes vidare i metoden. Med olika generaliserings-verktyg kunde strömhabitat identifieras och förstärkas. Även olika terrängmodeller skapades från flygfoton och Lantmäteriets nationella höjdmodell. Dessa granskades mot varandra utifrån olika aspekter som variationer i bland annat detaljrikedom, generaliseringsgrad och återspeglandet av vattenytan.  Slutsatsen av studien är att klassificering av strömhabitat kan göras i ett GIS-program med en lägesosäkerhet på mellan 25 och 40 %, beroende på vilka strömhabitat som ska klassificeras. Efter utrivningen uppstod 17 zoner med förändrade strömhabitat vilket var två mer än vad prognoser förutsatt. Vidare påverkades vattenvolymen markant då en minskning på ca 40 % skedde från 2018 till 2020. En areal av ca 1,5 hektar berördes då gammal älvbotten blev torrlagd i samband med dammutrivningen. Ett samband syntes mellan avståndet från kraftverket och torrlagd botten då dessa ytor sågs minska i storlek i takt med att avståndet ökade. Att undersöka vart vattennivån påverkats som mest var inte möjligt i brist på data. Studien har utvecklat en metod att analysera en dammutrivnings påverkan på ett vattendrag med data från UAV och bottenskanning.

(Our Exercise) website. This web application consists in one of the Tutorial Education Program Projects, PET-UFVJM/Mucuri Campus, located in Te?filo Otoni city, Minas Gerais state and it has as its objective the open share of teaching exercises of several knowledge areas. At the request of its creators, new functionalities were demanded to ?Nosso Exerc?cio? (Our Exercise), however, there were not clear goals for this project nor a work plan to be followed, the requirements were not formalised and the available team was not mature enough on the tecnologies applied. Considering the challenge faced on the generation of a good quality software and the time limit available for taking this research, the use of a software engineering was proposed aiming to get bigger quality control of the final Product to be developed. The agile method Scrum was the one chosen to manage the developing activities to this software. So, the general goal of this research consisted in searching for an answer to the following question-problem: Which benefits and/or difficulties can be obtained through the apllication of Scrum Framework on the evolution of the development of ?Nosso Exerc?cio? open plataforma? According to the model suggested by Coughlan and Coghlan (2002), the research-action method was used to describe a dinamic conducted during this work. The Scrum implantation on ?Nosso Exerc?cio? occurred in two stages, the first one, aimed to do a training about Scrum and the technological tools used in the development of ?Nosso Exerc?cio?. The second one, dealt with the development of functionalities to this website. The analyses of the results showed many benefits gotten with the implatation of Scrum in this project, like focus and commitment of ?Time? during its work, the attendance to the costumer?s real needs (Product Owner), the framework flexibility in adjusting to environment and work conditions of each ?Time? created, the continuous learning of the software and of the process resulting of the discussions taken on planning, reviewing and retrospecto meetings. The critical work point was about the immaturity with the technologies used for the website development. The learned lessons with this research indicate that it?s possible to get benefits with the implantation of Scrum Framework which overcome the difficulties, as long as the needed analysis of the enviroment where it was adopted be done.

The management of demolition waste in urban redevelopment projects is a major challenge requiring an integrative approach. This research demonstrates that multi-criteria decision analysis can improve and enable the demolition waste management decision-making process toward more sustainable urban redevelopment in Vietnam. This work has implications in assessing and qualifying demolition waste to more effectively achieve project cost and planning objectives in Vietnam.

This thesis outlines research completed in partnership between Merseyside Fire and Rescue Service and Liverpool John Moores University. The aim of the research was to investigate ways to develop and implement a bespoke Geographic Information System framework that could be used to identify risk of future anomalous accidental dwelling fires. This thesis outlines the techniques used to develop the framework and its application. In particular, the thesis presents an understanding of accidental dwelling fire causal factors and how data related to these can be incorporated into a model for identifying risk and targeting initiatives relative to the risk. The thesis also investigates two strands of customer insight developed for Merseyside Fire and Rescue Service. These are community profiles, based on a cluster analysis approach, to understand risks present within communities and the vulnerable person index, which identifies individuals most at risk from fire using data shared through information sharing agreements. Nationally recognised risk modelling toolkits, such as the Fire Service Emergency Cover toolkit do not utilise local information or have the ability to identify risk to an individual level. There is a need for this intelligence to be able to proactively target services, such as the Home Fire Safety Check. This paper also discusses some of the key operational and strategic areas that benefit from this information and presents some case studies related to the application of the research.

In this paper, I will show how applying a spatially explicit context to an existing environmental health surveillance framework is vital for more complete surveillance of disease, and for disease prevention and intervention strategies. As a case study to test the viability of a spatial approach to this existing framework, the risk of human exposure to Lyme disease will be estimated. This spatially explicit framework divides the surveillance process into three components: hazard surveillance, exposure surveillance, and outcome surveillance. The components will be used both collectively and individually, to assess exposure risk to infected ticks. By utilizing all surveillance components, I will identify different areas of risk which would not have been identified otherwise. Hazard surveillance uses maximum entropy modeling and geographically weighted regression analysis to create spatial models that predict the geographic distribution of ticks in Texas. Exposure surveillance uses GIS methods to estimate the risk of human exposures to infected ticks, resulting in a map that predicts the likelihood of human-tick interactions across Texas, using LandScan 2008TM population data. Lastly, outcome surveillance uses kernel density estimation-based methods to describe and analyze the spatial patterns of tick-borne diseases, which results in a continuous map that reflects disease rates based on population location. Data for this study was obtained from the Texas Department of Health Services and the University of North Texas Health Science Center. The data includes disease data on Lyme disease from 2004-2008, and the tick distribution estimates are based on field collections across Texas from 2004-2008.

With the increasing pressures and concerns in education regarding capability, lifelong learning, higher order cognitive skills, transdisciplinary education and so on, educators are seeking fresh ways to teach and new tools to support that teaching. In South Africa, Outcomes Based Education (OBE) has identified critical outcomes (skills) across all subject areas such as problem solving, teamwork, fostering critical thinking etc. as a way of responding to these pressures and concerns. But OBE has been criticised for lacking the necessary tools to develop these critical skills and to promote cross-discipline learning. One innovative way of offering transformative teaching, instruction and learning that may foster the development of these critical skills, particularly those concerned with critical thinking, is by using geographic information systems (GIS) technologies. The scope for using these technologies in secondary education is now being realised for teaching the more generic, cross-discipline skills described whereby students are learning not only about GIS but also with GIS. This realisation provides the opportunity to create flexible, computer-based learning materials that are rooted in authentic, real-world contexts, which aim to enhance the cognitive skills of the students. If these technologies can be used in an innovative way to develop critical outcomes and skills, a model needs to be defined to aid the design and development of learning materials using these technologies for use in schools. The primary aim of this study has been to develop such a model; a model which emphasises the development of real-world learning materials that develop higher-order thinking skills in learners. Another key product of this study is the submission of a comprehensive yet flexible framework for evaluating instructional design models found in the educational literature in order to determine if these design models can be used to develop learning materials forparticular contexts.

Nel corso degli ultimi venti anni, il 90% dei disastri è stato causato da inondazioni, tempeste ed altri eventi climatici. Le sole inondazioni, che hanno colpito circa 2,3 miliardi di persone in tutto il mondo, hanno rappresentato il 47% di tutti i disastri legati al clima. In tale contesto, a causa della loro maggiore vulnerabilità e relativamente minore capacità di adattamento, nei paesi in via di sviluppo i danni previsti sono più numerosi. Il rischio e l'impatto correlati alle inondazioni potrebbero, infatti, aumentare a causa dell'aumento dell'esposizione e della vulnerabilità di particolari elementi a rischio (recettori), legati sia alla dinamica di popolazione che al relativo sviluppo economico ed urbano in aree più a rischio. Di conseguenza, nelle aree potenzialmente interessate da eventi di inondazione e caratterizzate da alta densità di popolazione, diventa per lo più importante identificare specifiche strategie di adattamento e mitigazione al fine di prevenire e minimizzare impatti e danni legati al fenomeno d’interesse. Nell’ambito di questa tesi, mediante l’implementazione di una metodologia di valutazione dell’esposizione relativa ad eventi d’inondazione, è stata realizzata una valutazione mirata ad individuare aree e recettori (es. popolazione, infrastrutture, edifici ed aree agricole) potenzialmente colpiti da inondazioni fluviali nel caso studio del fiume Paraguay. L’utilizzo di Sistemi Informativi Territoriali (SIT) ha permesso l’elaborazione di mappe spaziali e relative statistiche rappresentative il potenziale impatto legato al fenomeno analizzato nonché le relative perdite nelle zone a rischio. Questi indicatori rappresentano valide informazioni da fornire a stakeholders locali e decisori politici, utili a supportare l'attuazione ed il raggiungimento degli obiettivi definiti nell’ambito del Quadro di Sendai per la Riduzione del Rischio di Catastrofi.

The development of information technology through Internet is disrupting the ways that people share and receive knowledge. Traditional communication channels, such as face to face-communication is to an increasing extent accompanied by knowledge sharing through digital communication channels. Furthermore, the digital channels offers methods to instantly charge for knowledge sharing with a monetary transaction. The gig economy is a concept that was first coined at 2009, but that has shown rapid and scalable growth in terms of both revenue and practitioners. Gigging, which is the main activity that is performed within the gig context, refers to working in an environment in which temporary work tasks are made by independent workers for short- term engagements. The purpose of this paper is to investigate one of the most recent trends within gigging, namely how to make extra money by sharing knowledge online. The study in this paper is done on Udemy.com, a platform that allows giggers to upload a video of a lecture. Potential buyers of these courses visit Udemy.com, search for what they want to learn, and will then be able to choose courses and tutors based on their own judgement. Knowledge sharing is not a new concept, e.g. lending books at libraries has been part of different cultures for a long time, but knowledge sharing through the gig economy context is a a rather new concept. Trust is key in online communities and gig platforms. On Udemy, giggers set up a profile, record a course and promote themselves in order to get more leads on their courses. Quality assurance of the course is a challenge in this context. Previous research has stated a few methods and principles to follow when gigging, but no research has been done on how to gigg within the context of knowledge sharing. The central research question in this paper is: “What aspects affect a potential buyer’s perceived trust towards tutor that has uploaded a course on Udemy.com?”. To answer the research question, a thoroughly literature study was made, convering the areas of building trust in the gig economy and the area of personal branding online. A conceptual framework was developed by comparing many different research articles within these fields, and finding common themes that builds trust for the potential buyer. A qualitative data collection was made by doing a think aloud-test on the gig platform Udemy.com. The think aloud study was done to verify the conceptual framework that was bought forward in the literature study, and to invetstigate further improvements of the framework. Trust is an abstract concept since it is based on a feeling, and qualitative research is more suitable than quantitative research to investigate these types of values. A think aloud study on the online platform Udemy.com was therefore done, in combination with a pre- and postinterview. The reason for doing a pre- and post- interview was to undertand the participants’ attitudes towards using a gig platform that offers knowledge sharing dynamics. The main aim of this study is to be able to bring forward a conceptual frmework that can be given to gig companies that strives for having an active marketplace, and that wants to help the giggers on the platform to sell their courses. Results from the qualitative study showed that the conceptual framework that was brought forward in the literature study, and subsequently tested in the qualitative interviews, was not sufficient to guarantee the participants’ perceived trust for the tutors. The conceptual framework was relevant, but many more aspects of building trust was discovered in the qualitative study. These aspects is relevant to investigate in further research. The discussion part of this paper discusses challenges in giiging knowledge sharing. It furthermore suggest improvement of investigation methodologies and further research in this context. Bringing forward the conceptual framework from an extensive literature review was central in this study. The qualitative data collection resultet in improvements of the framework. These contributions of improvement of the framework could however be tested further.<br>Utvecklingen av informationsteknik genom Internet konkurrerar med de traditionella informationskanalerna som används för att dela och sälja kunskap. Giggande är ett koncept som först myntades 2009, men det har visat en snabb och skalbar tillväxt. Att "gigga" innebär att arbeta i en miljö där tillfälliga arbetsuppgifter utförs av oberoende arbetstagare för korta åtaganden. Syftet med denna studie är att undersöka en av de senaste trenderna inom gigging, nämligen hur man kan tjäna extra pengar genom att dela kunskap. En kvalitativ studie har gjorts på gig- plattformen Udemy.com, en plattform som tillåter giggare att ladda upp en video på dem själva när de håller en föreläsning. Potentiella köpare av dessa kurser besöker Udemy.com, söker efter vad de vill lära sig och kommer slutligen att kunna välja kurser utifrån sin egen bedömning. Kunskapsdelning är inte ett nytt koncept, t.ex. utlåningsböcker på bibliotek har länge varit en del av olika kulturer. Giggare är ansvariga för att skapa sin egen profil, spela in sin kurs och marknadsföra sig för att få mer efterfrågan på sina kurser. Tidigare forskning har angett några metoder och principer att följa när det kommer till giggande, men ingen forskning görs på hur man bör göra för att gigga inom ramen för kunskapsdelning. Trovärdighets- begreppet är nyckeln till onlinesamhällen enligt tidigare forskning. Den centrala forskningsfrågan i detta dokument är: "Vilka aspekter påverkar en potentiell köpares uppfattade förtroende mot kursansvariga som har laddat upp en kurs påUdemy.com?" För att svara på frågan gjordes en grundlig litteraturstudie som berörde områdena för att bygga förtroende i gig-ekonomin och även området för personlig marknadsföring online. Ett konceptuellt ramverk utvecklades genom att jämföra många olika forskningsartiklar inom dessa områden och hitta gemensamma teman som för den potentiella köparen bygger förtroende gentemot giggaren. För att kontrollera om ramverket var relevant när det gäller att bygga förtroende hos potentiella kunder, gjordes en kvalitativ datainsamling där potentiella kunder fick göra en användarstudie ("tänka högt"-studie) på gig plattformen Udemy. Trovärdighetskonceptet baseras på användarnas känsla och åsikter gentemot giggaren, och kvalitativ forskning är mer lämplig än kvantitativ forskning för att undersöka dessa typer av värderingar (känslor och åsikter). Användarstudien på Udemy kompletterades även med en före- och efterintervju.Anledningen till att göra en för- och efter-intervju var att få en generell uppfattning av deltagarnas inställning till att använda en gig-plattform som erbjuder kunskapsdelning. Syftet med studien var att det framtagna konceptuella ramverket skulle kunna användas av gig- företag som vill uppnå en aktiv marknadsplats, där giggarna lyckas sälja sina kurser. Resultat från den kvalitativa studien visade att det konceptuella ramverket som togs fram i litteraturstudien och som därefter testades i de kvalitativa intervjuerna, inte var fullt tillräcklig för att garantera trovärdighet. Det konceptuella ramverket var relevant, men många fler aspekter av att bygga förtroende upptäcktes i den kvalitativa studien. Dessa aspekter kan vara tillämpliga inom ytterligare forskning i samband med giggande av kunskapsdelning genom video på en gig-plattform. Diskussionsdelen av det här dokumentet diskuterar utmaningar i att ge kunskapsdelning online inom en gigkontext. Diskussionsdelen föreslår vidare förbättring av undersökningsmetoder och ytterligare forskning i detta sammanhang. Att föra fram det konceptuella ramverket från en omfattande litteraturgranskning var central i denna studie. Den kvalitativa datainsamlingen resulterade i förslag på förbättringar av ramverket, samt förslag på hur ramverket kan testas ytterligare.
