This thesis presents two studies of computer-mediated non-monetary exchange. The Internet has improved the potential for previously unconnected people to organise into interest groups with the intent of meeting offline. This has resulted in a range of organisations emerging with the explicit aim of helping people to give and share resources. These organisations typically reject money and markets, insisting that social interaction should occur through generosity alone. The first study presents a netnography and depth interviews which reveal how technology is used to enact and influence the management of identity, partner selection, ritual normalisation, and negotiation of property rights. The findings have significant implications for the design and management of systems that encourage non-monetary forms of collaborative consumption. In the second study a longitudinal social network analysis reveals how the social structures involved in these systems have no obvious historical precedent. This has implications for the way in which the social sciences should conceptualise reciprocal economic arrangements. It also raises some sociological implications for the possibility of designing economic systems in the absence of money. Finally, a new approach is proposed which advocates diachronic analysis of property rights as a means to explain how markets and institutions that try to subvert markets exist alongside each other.

<p> This thesis project created a landscape design framework for the Student Garden at the College of Charleston that took into account stakeholder needs and landscape constraints, thereby allowing the Garden to better fulfill its mission. Steps for this project were to perform a stakeholder analysis to determine perceptions of mission, vision, and needs for the Garden. This was then paired with a landscape suitability assessment. The assessment was performed in GIS using available soil data from the Soil Survey Geographic Database (SSURGO) to analyze for agricultural suitability.</p><p> Based on interview data, stakeholders considered the main mission of the Garden to lie in three areas: education, student research projects, and vegetable production. Landscape suitability analysis determined that the Garden was situated in the least favorable location within its available land area from an ecosystem standpoint. The landscape design incorporated the stakeholder needs of education, research, and production while proposing an expansion in a new, more centralized location that has soil better suited for agriculture along with new infrastructure. It incorporated a centralized building with office, rest area, and shaded work area that has facilities approved for vegetable processing for the CSA. Adjoining the building are beds showcasing sustainable agricultural techniques, greenhouses for seed starting and production, area for a food forest, and open fields for row crops.</p>

M. Tech. (Department of Civil Engineering and Building, Faculty of Engineering and Technology), Vaal University of Technology / Growth in land development in South Africa resulted in large increase in traffic volumes. A Traffic Impact Assessment (TIA), as a traffic engineering tool, is commonly used to assess the possible effects of a land development project on the transportation and traffic system. During the TIA process, capacity analysis is performed to indicate the measures of effectiveness of the intersection. Intersection capacity analysis in South Africa by engineers is done on the basis of default values of the Peak Hour Factor (PHF) provided by the Highway Capacity Manual (HCM) or limited traffic counts. However, the default value of PHF may be significantly affected by new developments in the neighbourhood of the intersection. This study aimed at investigating the impact land-use change has on the existing intersection PHF, thus predicting values per land-use type. Intersections with traffic counts conducted before and after land-use change in vicinity were selected and investigated. The results showed that change in land-use has an impact on the existing PHF. They also assist in identifying the appropriate intersections to predict the PHF per land-use type. Intersections were identified and analysed, and this led to the development of a design chart showing the predicted PHF per land-use type selected and measures to consider during traffic analysis. Intersection capacity analysis was performed to compare the results using the predicted PHF and the HCM default values. The results showed that traffic flow rate was adjusted by up to 26% when using the default values, 0.92 and 0.95. The results also showed that the default values could overestimate the volume to capacity ratio and the average delay by up to 15% and 35%, respectively. It was then concluded that the use of HCM default values of the PHF for every land-use type will have an effect of the final roadway design results. The computed PHF values for each land-use type were then recommended to be used to ensure fairness and consistency in traffic analysis.

Agriculture represents a class or expression of complexity which researchers need to look at because of its immense contribution to rural development and poverty reduction. Scientists and researchers per their disciplinary training and specialisations differ in wider perspectives and methodologies. In addition to the compartment functioning processes of organisations, fluid interaction and collaboration of actors are further limited. This study examines how actors in Crops for the Future (CFF) interacted formally and informally as a complex agricultural research organisation to address the transdisciplinary communication challenges it faces. Using ethnographic methods with participant observation, interviews and official document reviews, the study revealed that, the structuring of CFF into themes and programmes was intended to network and work in their areas of disciplines. The study revealed that internal policies of CFF such as the research value chain (RVC), the doctoral support programmes (DTP) and flagship projects aim to improve research collaboration and as a research strategy, tend to support working together effectively. However, it further revealed that, though actors collaborate and network across different knowledge communities, elements of personal interest and power appear to play a significant role in that drive. Raising questions of communication and reporting process, revealed a mixed form of vertical and horizontal hierarchies, supported by a project and functional structures of management in CFF. The informal practices of actors in CFF (social networking, friendship, interactions etc.) tend to strongly support and enhance the formal structures and policies (programmes, themes, reporting and management structure etc.).

Chapter 1: Land Inequality and Human Capital: Evidence for the United States from the Homestead Act. This chapter uses historical records of land patents and county level census data to estimate the impact of the Homestead Act of 1862 |an egalitarian land distribution policy implemented in the United States| on land inequality, school enrolment, and literacy during the late nineteenth and early twentieth centuries. The results show that the Homestead Act reduced land inequality and increased school enrolment and literacy, and that there is not heterogeneous effects on school enrolment by sex, but the effect is driven by the impact on children of primary school age. Using the Homestead Act as an instrument for land inequality, the results show that land inequality had a strong negative impact on school enrolment. This result is relevant to the literature because identification does not rely on variation across geographic, climatic, or soil characteristics. These results are robust to the inclusion of state specific year fixed effects and are not driven by convergence. On the contrary, I argue that convergence in school enrolment was a consequence of the Homestead Act. Chapter 2: Land Redistribution and Crop Choice: Evidence from Reform and Counter-Reform in Chile. This chapter uses unique historical data on the Chilean land reform of the 1960s and 1970s to estimate the impact that redistribution had on land inequality and crop choice. The results show that land redistribution had a persistent negative effect on land inequality, and that areas that were treated with more reform increased their share of land cultivated with fruits, vegetables, and vineyards, and lowered the share of land destined to forest plantations. The fact that a military coup interrupted the reform process allows for the comparison of the effects of reform and counter-reform, which sheds light on the mechanisms through which redistribution operated. I find that land that was transferred to new owners drive the results for crop choice, but not those for land inequality. Chapter 3: Earthquakes and Birth Outcomes in Chile. This chapter estimates the e effects of earthquakes on birth weight and length of gestation. I use administrative data on the universe of live births in Chile between 1994 and 2011. I combine that data with GIS raster information from USGS ShakeMaps to assign a detailed measure of earthquake intensity for each birth during each trimester of pregnancy. I find that, although the baseline estimates suggest a weak negative effect, these results are not robust to the exclusion of births from a strong 8.8 magnitude earthquake that struck off the coast of south-central Chile, which caused approximately 500 casualties, heavy infrastructure damage, and significant disruption to the government's logistics.

China has been experiencing constraints to the sustainable development of its domestic economy in recent years due to a reliance on a low value-added oriented economy. The enhancement of innovation among local firms is, therefore, being encouraged by the Chinese government. The Chinese government regards the automotive industry as one of its strategic industries yet the local automotive firms in China still remain relatively under-developed due to a limited independent innovation capacity. Therefore, the enhancement of an indigenous innovation capacity in the automotive industry is badly needed. Favourable policies have been applied in the automotive sector in order to support the technological development of local automotive firms which includes the constraints on foreign direct investment (FDI) in the automotive sector. Automotive multinational corporations (MNCs) are strictly required to establish international joint ventures (IJVs) with local automotive firms and can own no more than a 50% share in an IJV. The logic behind this is to protect the local automotive firms and allow them access to the technological resources of the MNCs and the opportunity for organisational learning. This logic is supported by current literature as IJVs are, arguably, able to deliver innovation outputs through direct access to the resources of the parent companies and the interpartner learning effects. Despite this, real-life examples suggest a limited innovation performance in the automotive IJVs in China. The innovation achievements are largely limited to minor changes to established products and some new products based on existing technologies. Whilst there is little technological innovation apparent in the automotive IJVs in China, there is evidence of this emerging from local automotive firms without the assistance of an IJV partnership. This PhD thesis explores the underlying reasons for the gap between current academic theory and the reality in the automotive industry. Qualitative case studies of three Chinese automotive IJVs and one independent local automotive firm with a reputation for innovation were conducted to investigate the factors that limit innovation activities in automotive IJVs. The findings of this research suggest that the IJV partnership itself is a constraining factor in the context of the Chinese automotive industry. This is because the nature of automotive IJVs in China lead to a lack of strategic focus on innovation and the IJVs follow a closed innovation paradigm as they only benefit from the limited resources of their parent companies, with little or no access to other external resources. Furthermore, the mismatch of the technological capabilities causes ineffectiveness in the utilisation process of the transferred resources. This research contributes to knowledge by explaining the gap between current theories on IJV and the reality within the industry. Furthermore, a revised model of knowledge management is proposed in the context of IJVs. In light of the main research findings, recommendations are made regarding the policy and practice of using IJV partnerships for the enhancement of innovation capacity among Chinese firms.

In recent years there has been an increase in metrics and indices measuring corporate social responsibility (CSR) (SuatainAbility, 2010; IBE, 2013). In legitimating the premise of these metrics focus has centred on the effects of inclusion, either in regard to financial impact for the firm (Beurden and Gössling, 2008; Griffin and Mahon, 1997), validity in gaining and conveying legitimacy (Chatterji et al, 2007; Agle and Kelly, 2001; Font et al, 2012; Graafland et al, 2004), or social impact in promoting responsible business practices (Slager et al, 2010; Slager, 2012; Adam and Shavit, 2007; Scarlet and Kelly, 2009). Yet, arguably these tools are now institutionalised elements of CSR (Waddock, 2008), and thus focus is no longer centred on gaining legitimacy, but rather on retaining it, as they 'face the need to evolve ... in the context of the changing demands of constituents and environmental change' (Durand & McGuire, 2005, p.168). However, little is known about how these effects (financial, social and validity) impact the valuation dynamics associated with participation in these tools over time. This thesis aims to fill this gap by exploring processes of legitimation and critique of participation in Business in the Community's Corporate Responsibility Index (BiTC's CRI). Through the lens of Boltanski and Thévenot's economies of worth (2006), the thesis examines the 'orders of worth' drawn upon in legitimating and critiquing participation in the CRI over time. Methodology is abductive, with data and extant theory explored simultaneously so as to establish contributions through a mutually-informed comprehension of what the data is a 'case of' (Tavory & Timmermans, 2014, p.5). Research-theorising applies Peircean semiotics (Peirce, 1909), by which, extant literature and theorising are applied, tested, and either set aside from/or built-upon, when set against the data of the empirical case. Data collection is qualitative, consisting of observations (4 formal and numerous informal), interviews (68) and documentary analysis. The research ultimately draws on Boltanski and Thévenot's Economies of Worth (2006), and the notion of 'composite assemblages', developed further by Mailhot & Langley (2017), Gond et al (2017) and Taupin (2012). The thesis supports Taupin's (2012) suggestion; that a rating's legitimacy is based on a collection of 'moral worths' (p.529), and conceptualises this through the 'composite assemblage' advanced by (Mailhot & Langley, 2017). Analysis contributes to scholarly understanding of processes of legitimation, by unpacking the relative 'robustness' of an assemblage, to internal and external 'tests' of worth. In unpacking these processes, the thesis brings together theory from EW, 'substantive and symbolic CSR', materiality, risk, and boundary objects; to uncover a complex 'web' of dynamic central, and peripheral value assemblages, which BiTC staff and participating CR practitioners draw upon, in legitimating and critiquing participation in the CRI.

Knowledge Management (KM) in this research refers to a process that dives deep into an organization and analyzes operational metrics to understand and help the enterprise make use of knowledge both explicit and tacit, facilitate a state of knowledge awareness and sustain the knowledge managing and learning process. This novelty of the research is its first attempt to combine China's KM implementation issues statistics, literature review on KM model and KM CSFs, integrating with research objectives findings to develop a KM framework for China SME shipyards. This framework interlinks the knowledge cycle of knowledge acquisition, application and improvement continuously within organization by 3 KM domains of organization entity, people interaction and organization memory, formulated by 12 KM CSFs derived. The uniqueness of this framework is it emphasis on people. Organization entity involves people support of top management to motivate and drive organizational culture to embrace KM. Continuous organization knowledge improvement involve people interaction to facilitate knowledge processes through socialization programs, training and building of trustworthy team. People are the one who contribute to organization memory by retain and update organization knowledge for effective reprocessing and retrieval via information technology. The survey took the form of structured interview in five stages of field study with eight sets of survey questionnaires. AHP method is applied to quantify practices and translate it into measurable absolute numbers. Result showed that one third of China SME shipyards are NOT Ready for KM implementation. Among the deficiencies, knowledge structure is the first limitation, followed by the knowledge content and training. The value of this research is to highlight and illustrate to enterprises the opportunity of the application of KM Framework could continuously improve their organization knowledge from operating processes through systematic knowledge acquisition and application, to gain their competitiveness and sustainability in long term. In short term, this KM framework by application could answer to the question that all China SME shipyards unanimously asked "Do you think my shipyard is ready to implement Knowledge Management?"

Land use optimization is a multifaceted process that entails complex decision-making which involves the selection of activities, the percentages to allocate, and where to allocate. It will also add a whole extra class of variables to the problem when combined with the inevitable consideration of spatial optimization. The related applications by linear programming (LP), "Pareto Front Optimal" based methods, heuristics methods and integration of GIS etc. for spatial multi-objective land use optimization are reviewed and analyzed on their advantages and disadvantages in this thesis. Accordingly, due to the nonlinearity and the complexity caused by the multiple objectives and increasing variables during the optimization process, the efficiency and effect would be the issues to be considered. The need for effective and efficient models for land use optimization is evident from the above discussion as the core content. In order to comprehensively fulfill all the requirements, the understanding of the sustainability of land use is translated into eight objectives to form the Multi-objective Optimization of Land Use (MOLU) model. Furthermore, an efficient model named Boundary based Fast Genetic Algorithm (BFGA) using goal programming is employed in the multi-objective optimization in Tongzhou Newtown. This algorithm is especially efficient for land use optimization problems derived from its special boundary based operators. Furthermore, considering the characteristics of planning support process and these two models mentioned above, the interactive spatial land use optimization prototype with a friendly interface and a simplified 3D visualization module could be established, thus yielding good effects and potential to support the planning process in the study area. Finally, in light of the study results and limitations, some directions are also provided for future research. / Land use optimization, a kind of resource allocation, can be defined as the process of allocating different land use categories (e.g., residential, commercial, and industrial, etc.) to specific units of area within a region. As one of the most popular words nowadays, sustainable development can be viewed as a process of change in which the exploitation of resources, the direction of investment, the orientation of technological development and institutional change are all harmonized. Sustainability is, hence, an important and imminent societal goal for land use planning. Land use optimization involves the active planning of land for future use by people to provide for their needs. In this thesis, the central goal is to develop a sustainable land use optimization prototype to enrich the field of planning support with regard to sustainability. / Cao, Kai. / Source: Dissertation Abstracts International, Volume: 72-04, Section: A, page: . / Thesis (Ph.D.)--Chinese University of Hong Kong, 2010. / Includes bibliographical references (leaves 132-139). / Electronic reproduction.

This thesis consists of three self-contained studies on corporate tax avoidance of Chinese firms around the 2008 Corporate Tax Reform. In Chapter 1, we describe the background of this thesis, provide a general introduction of the Tax Reform and outline the motivation of this research. Chapter 2 studies how multinationals’ decisions of foreign direct investment (FDI) into China responded to the tax reform where exemption from the dividend withholding tax was repealed and investors from various jurisdictions faced different withholding tax rates due to their existing double tax agreements (DTA) with China, providing incentives to adopt an indirect strategy for foreign affiliates and thus to reduce host country taxation of foreign income. We find a significant rise in FDI flows sourced from low tax conduit jurisdictions with favorable DTA subsequent to the tax reform, while there is no similar increase in FDI flows sourced from other jurisdictions. In addition, our results suggest that the pattern of FDI changes is similar for jurisdictions adopting divergent double tax relief mechanisms. Overall, our findings are supportive of the existence of indirect investment structures in which investors use conduit strategies via chains of ownership in order to minimize their corporate tax burden. Chapter 3 investigates whether and how firms shift income across consecutive years in response to a known schedule of tax rate changes. Both accruals-based and real earnings management models are tested for firms with tax rate increase or decrease. We find that firms expecting tax rate increase are more likely to manage their earnings upward via accruals instead of real activities, while firms facing tax rate reduction do not exhibit significant downward earnings management behavior via accruals or real activities. Our tests also show that state or institutional ownership do not have significant impact on the extent of accruals-based or real earnings management in response to tax rate changes. Chapter 4 studies the changes in effective tax rates (ETR) and book-tax differences (BTDs) of firms in response to a rise or cut in statutory tax rate during a major tax reform in an emerging market, and offers insights into the interaction of financial accounting considerations with corporate tax avoidance. We find that firms located in special economic zones (SEZ) with a rising statutory tax rate after tax reform exhibit a rise in ETRs and permanent BTDs, but the temporary BTDs of SEZ firms dropped after CTR-08, suggesting a trade-off of time value benefits of deferring tax payment for the advantage of accelerating tax payment during a period of rising tax rate. DR firms, on the other hand, show a decrease in ETRs and permanent BTDs when they face a decrease in statutory tax rate. In Chapter 5, the main findings and implications of the thesis are summarized and future research directions are discussed.
