    In addition to the studies that provide meaningful insights into the complexity of technical and economic issues, increasing studies have focused on the political process of market transition in network industries such as the electric power sector. This dissertation studies the central–provincial interactions in industrial policy-making and implementation, and attempts to evaluate the roles of Chinese provinces in the market reform process of the electric power sector. Market reforms of this sector are used as an illustrative case because the new round of market reforms had achieved some significant breakthroughs in areas such as pricing reform and wholesale market trading. Other policy measures, such as the liberalization of the distribution market and cross-regional market-building, are still at a nascent stage and have only scored moderate progress. It is important to investigate why some policy areas make greater progress in market reforms than others. It is also interesting to examine the impacts of Chinese central-provincial politics on producing the different market reform outcomes. Guangdong and Xinjiang are two provinces being analyzed in this dissertation. The progress of market reforms in these two provinces showed similarities although the provinces are very different in terms of local conditions such as the stages of their economic development and energy structures. The actual reform can be understood as the outcomes of certain modes of interactions between the central and provincial actors in the context of their particular capabilities and preferences in different policy areas. This dissertation argues that market reform is more successful in policy areas where the central and provincial authorities are able to engage mainly in integrative negotiations than in areas where they engage mainly in distributive negotiations

    Includes supplementary material. Please contact [email protected] for access.When the Islamic State used Unmanned Aerial Vehicles (UAV) to target coalition forces in 2014, the use of UAVs rapidly expanded, giving weak states and non-state actors an asymmetric advantage over their technologically superior foes. This asymmetry led the Department of Defense (DOD) and the Department of Homeland Security (DHS) to spend vast sums of money on counter-unmanned aircraft systems (C-UAS). Despite the market density, many C-UAS technologies use expensive, bulky, and high-power-consuming electronic attack methods for ground-to-air interdiction. This thesis outlines the current technology used for C-UAS and proposes a defense-in-depth framework using airborne C-UAS patrols outfitted with cyber-attack capabilities. Using aerial interdiction, this thesis develops a novel C-UAS device called the Detachable Drone Hijacker—a low-size, weight, and power C-UAS device designed to deliver cyber-attacks against commercial UAVs using the IEEE 802.11 wireless communication specification. The experimentation results show that the Detachable Drone Hijacker, which weighs 400 grams, consumes one Watt of power, and costs $250, can interdict adversarial UAVs with no unintended collateral damage. This thesis recommends that the DOD and DHS incorporates aerial interdiction to support its C-UAS defense-in-depth, using technologies similar to the Detachable Drone Hijacker.DASN-OE, Washington DC, 20310Captain, United States Marine CorpsApproved for public release.

    A Theory Kit for World History

    Get PDF
    This report presents a “kit” of theories regarding major processes in human history formed into a whole, a “theory kit”, with the aim to understand how these processes unfold over thousands of years. The theory kit has an underlying fundamental theoretical approach concerning dialectical, contradictory, processes as a core of the complex matrix that shapes human history. In the kit, history is presented in three spheres that are given equal importance: material culture, social structure and societal mentality. An enigma in world history is the common rhythm: different parts of the world tend to move at the same time and in the same direction. The claim here is that the enormous interacting complexity is one explanation of this relative unity in change. In the theory kit a number of issues are discussed, such as: Axial Ages, class struggle, empires, expansion-stagnation-crisis, agricultural world systems, technological complex(es), mentality world systems, invention-innovation

    Impacts of Various Connectivity Processes in Central Asia on Sustainable Development of Kyrgyzstan

    Get PDF
    Kyrgyzstan is facing a strategically important period in its history. The government’s ambition of reindustrializing is affecting its engagement with various international organizations and donors. As these plans will lead to societal transition and affect such areas as social development, national economy, and environment, a careful consideration of their impacts is required, especially given the country’s need to achieve sustainable development. At the same time, the geographical position of Kyrgyzstan puts it at the cross-roads of three distinct regional economic connectivity processes: the Eurasian Economic Union (EAEU), the China-led Belt and Road Initiative (BRI), and various connectivity initiatives and projects taking place under the umbrella of the European Union (EU). A major issue is the extent to which Kyrgyzstan can leverage these processes to boost its economic revitalization plans and decarbonize its economy in line with international climate change mitigation and energy security policies, while ensuring a reliable energy supply. As a result, novel governance mechanisms need to be established that address the possible impacts of these economic connectivity processes; this is especially important given the frequently diverging perceptions and opinions of the various Kyrgyz and foreign stakeholders involved in industrial policymaking. Perceptual heterogeneity influences the development of solutions based on compromise and participatory governance that are crucial to implementing different industrial policy options; it also impacts the nature of the economic relationship between Kyrgyzstan and other countries in the Central Asian region. The aim of this paper is to understand the implications of perceptual heterogeneity for the various connectivity processes in Kyrgyzstan, their benefits, and their impacts. The methodology of this paper includes a variety of methods such as surveys and interviews with key stakeholders, scenario development, and participatory workshops in various regions of the country

    The United Nations World Water Development Report 2022 : groundwater : making the invisible visible

    Get PDF
    Accounting for approximately 99% of all liquid freshwater on Earth, groundwater has the potential to provide societies with tremendous social, economic and environmental benefits and opportunities. Groundwater already provides half of the volume of water withdrawn for domestic use by the global population, including the drinking water for the vast majority of the rural population who do not get their water delivered to them via public or private supply systems, and around 25% of all water withdrawn for irrigation. However, this natural resource is often poorly understood, and consequently undervalued, mismanaged and even abused. Groundwater is central to the fight against poverty, to food and water security, to the creation of decent jobs, to socio-economic development, and to the resilience of societies and economies to climate change. Reliance on groundwater will only increase, mainly due to growing water demand by all sectors combined with increasing variation in rainfall patterns. The report describes the challenges and opportunities associated with the development, management and governance of groundwater across the world. It aims to establish a clear understanding of the role that groundwater plays in daily life, of its interactions with people, and of the opportunities for optimizing its use in order to ensure the long-term sustainability of this largely available yet fragile resource. Unlocking the full potential of groundwater will require strong and concerted efforts to manage and use it sustainably. And it all starts by making the invisible visible

    The Resilience and Sustainability of Suranga Irrigation in the Western Ghats of India

    This study focused on a little known traditional water management system, known as suranga, historically used by marginalised agricultural communities in the remote foothills of the Western Ghats in India to evaluate the resilience and sustainability of the suranga system. A hill irrigation analytical framework was used to provide a pragmatic epistemology. The research methodology was interdisciplinary, incorporating mixed methods taken from both the physical and social sciences to answer five research questions about suranga linked to their history, distribution, design principles, operational characteristics, governance, and organisation. Results suggest that suranga originate from the early 20th century. A field survey, supported by in-depth interviews of suranga users (n=173), found 700 suranga mainly distributed in fourteen villages in the Dakshin Kannada and Kasaragod districts. Data from previous studies, including this study, suggest there are a minimum of ~3000 suranga in the region as a whole. Suranga were defined as a groundwater collection gallery filtration tunnel system sourced from perched aquifers. Key strengths of the system were found to be the basic design principles, flexible excavation approaches, adaptability, clear use boundaries, relatively low construction and maintenance costs, self-regulated discharge, private ownership and management, and ease of access. Weaknesses of the system were a laborious and risky excavation process, limited water yield, non-collaboration, the absence of governance, and low earnings for suranga workers. Suranga were also found to be vulnerable to pollution, forest cover loss, and the impacts of climate change. However, suranga have contributed to a resilient and sustainable community in the past when the population, water demands, and the size of the irrigated area were low, and farm choices were limited. Currently, the suranga system may soon be unable to meet increased water demands because of population increase, intensification and reorientation of agriculture, alternative borewell technology and improved socioeconomic conditions. However, Suranga do retain some humanitarian relevance to farmers in the study area having improved the quality of life for many low-income families, but new emerging endogenous and exogenous pressures may make them vulnerable to changes in the future that cause the collapse of the system unless further adaptation occurs
