集合住宅社區共同使用部份屬於住戶分別共有的「共有資產」，具有類似公共財的特性，可能會因為相關使用衝突課題，或集體行動困境，而減損多數願意配合社區事務的住戶之使用效益。此外，代理問題可能衍生自管理委員會所建立的管理模式，其影響程度可能因決策控制權及管理權不同程度的委外而有異。 因此，本論文主要有三個探討課題：第一，從集體行動困境角度分析並釐清管理委員會自治管理問題；第二，依據代理理論、公司治理機制，從決策控制權移轉的程度來重新定義集合住宅社區的事務管理模式，分析事務管理模式對於管理維護效率的影響；第三，了解使用混合與面積混合所產生的使用衝突與管理維護績效間的相互關係。本文使用台北集合住宅管理維護現況調查的問卷資料進行實證研究，期望透過上述課題的探討，釐清管理維護潛在問題，並對不同類型社區提出適宜管理維護方式的建議，產生兼具學術與實務面之貢獻。 / Common property belonging to all owners of a condominium may cause usage conflicts or collective action dilemmas, due to the characteristic of quasi-public goods diminishing most residents' utility or benefits. Besides, agency problems derived from different management modes established by management committees may have unfavorable influence on management performance to some extent ccording to the delegation degree of decision control and management. Therefore, the main topics of this dissertation are as follows: First, analyzing and cectifying the collective action dilemmas through the self-organized CPR regimes; Secondly, redefining condominium management modes through delegation or outsourcing degrees of decision control according to agency theory and corporate governance framework and analyzing the effects of these modes on management performance; Thirdly, discovering the relationship between usage conflicts derived from the features of housing mix and usage mix and management performance of condominiums. Data collected from a postal questionnaire survey in Taipei city was used in several empirical analyses based on the main topics. Clarify the potential problems of condominium management and proposing appropriate management modes and approaches according to various features of condominiums are expected to be both academic and practical contributions.

Thesis (M. Sc.(Geography)) -- University of Limpopo, 2019 / Global production of Platinum Group Metals (PGMs) is dominated by South Africa due to its large economic resources base in the Bushveld Igneous Complex (BIC). PGMs are used in a wide range of high technology applications worldwide including medicinal, industrial and commercial purposes, and its contribution to the Gross Domestic Product (GDP) and creating jobs for many. In an area where mining activities dominate, there are likely to be problems that need effective environmental management approaches, which can be facilitated through legislations. Marula Platinum Mine (MPM) is located in Limpopo province BIC which has the second largest number of mining productivity in South Africa. Environmental legislations have been put in place by the South African government in order to avoid or minimise the footprints caused by PGM mining. This study looked at environmental compliance with solid waste management practices by Marula Platinum Mine (MPM) as guided by Mineral and Petroleum and Resource Development Act (MPRDA) and National Environmental Management Act (NEMA) as well as the environmental impacts of MPM in the surrounding communities. Both primary (questionnaires, field observations and key informant interviews) and secondary (NEMA, MPRDA, journals, reports, pamphlets, internet and books) data was used to address the objectives of the study. Descriptive method and Statistical Package for Social Sciences (SPSS) version 25 were used for the analysis of data. The key research results revealed that MPM was compliant with 65% and 21% partially compliant with solid waste management practices. Only 14% of information on solid waste management practices could not be accessed because MPM is still operational. MPM had also had negative footprints on the surrounding villages such as dust generation and cracks on walls and floors on houses of community members, strikes and increase in the usage of substance abuse. Recommendations of the study are that MPM should address challenges that hinder environmental compliance so as to be 100% compliant with MPRDA and NEMA regulations. MPM should also provide other mitigation measures for blasting of explosives to reduce dust generation and problems of cracks on houses of surrounding village members.

Infrastructure is presenting significant national and global challenges. Whilst often seen as performing well, infrastructure tends to do so against only limited terms of reference and short-term objectives. Given that the world is facing a new infrastructure bill of ~£40T, improving the benefits delivered by existing infrastructure is vital (Dobbs et al., 2013). This thesis investigates strategic intent and the management of infrastructure systems; how factors such as organisational structure and business practice affect outcomes and the ways in which those systems — not projects — are managed. To date, performance has largely been approached from the perspective of project investment and/or delivery, or the assessment of latent failures arising from specific shocks or disruptive events (e.g. natural disaster, infrastructure failures, climate change). By contrast, the delivery of system-level services and outcomes across the infrastructure system has been rarely examined. This is where infrastructure forms an enduring system of services, assets, projects, and networks each at different stages of their lifecycle, and affecting one another as they develop, then age. Yet system performance, which also includes societal, organisational, administrative and technical factors, is arguably the level relevant to, and the reality of, day-to-day public infrastructure management. This research firstly investigated industry perceptions in order to test and confirm the problem: the nub of which was the inability to fully deliver appropriate and relevant infrastructure outcomes over the long term. Three detailed studies then explored the reasons for this problem through different lenses; thereby providing an evidence-base for a range of issues that are shared by the wider infrastructure industry. In confirming its hypothesis that “the strategic intent and the day-to-day management of infrastructure systems are often misaligned, with negative consequences for achieving the desired long-term infrastructure system outcomes”, this research has increased our understanding of the ways in which that misalignment occurs, and the consequences that result. It found those consequences were material, and frequently not visible within the sub-system accountable for the delivery of those outcomes. That public infrastructure exists, not in its own right, but to be of benefit to society, is a central theme drawn from the definition of infrastructure itself. This research shows that it is not enough to be focused on technical outcomes. Infrastructure needs to move beyond how society interacts with an asset, to the outcomes that reflect the needs, beliefs, and choices of society as well as its ability to respond to change (aptitude). Although the research has confirmed its hypothesis and three supporting propositions, the research does not purport to offer ‘the solution’. Single solutions do not exist to address the challenges facing a complex adaptive system such as infrastructure. But the research does offer several system-oriented sense-making models at both the detailed and system-level. This includes the probing methodology by way of a diagnostic roadmap. These models aim to assist practitioners in managing the transition of projects, assets, and services into a wider infrastructure system, their potential, and in (re)orienting the organisation to the dynamic nature of the system and its societal imperative.
