<p>This minithesis seeks to understand why infrastructure projects fail to contribute effectively to poverty (rural) reduction. The thesis assumes that though infrastructure provision can impact positively on rural poverty reduction, the same infrastructure provision has worsened or put people in worse conditions of poverty. Therefore it is not automatic that infrastructure provision would reduce rural poverty as often held. The thesis goes on to postulate that a positive relationship between infrastructure and rural poverty reduction is best achieved within a broad or generic policy which provides the framework for providing such infrastructure. The thesis assesses these assertions empirically by first, testing the relationships between infrastructure and rural poverty reduction. Here a large scale infrastructure project in Ghana known as the Keta sea defence project serves as the case study. Secondly the thesis assesses Ghana&rsquo / s infrastructure provision policy environment and its implications on rural poverty reduction in the affected communities of the Keta sea defence project.</p>

Content Centric Networking (CCN) is a novel networking architecture in which communication is resolved based on names, or descriptions of the data transferred instead of addresses of the end-hosts. While CCN demonstrates many promising potentials, its current implementation suffers from severe performance limitations. In this thesis we study the performance and analyze the bottleneck of the existing CCN prototype. Based on the analysis, a variety of design alternatives are proposed for realizing high performance content centric networking over virtual infrastructure. Preliminary implementations for two of the approaches are developed and evaluated on Smart Applications on Virtual Infrastructure (SAVI) testbed. The evaluation results demonstrate that our design is capable of providing scalable content centric routing solution beyond 1Gbps throughput under realistic traffic load.

Protection of the agriculture and food infrastructure, defined as "the physical production and distribution systems critical to supporting national security and economic well-being, including all activities essential to food, feed, and fiber production, including all techniques for raising and processing livestock," is the responsibility of all stakeholders in the food supply chain (Spellman, 2008, p.8). Though many stakeholders emerge in the chain, producers are the primary line of defense to a disease epidemic. Many factors influence livestock producers‘ protective action decision process in relation to biological hazards. By identifying these factors in a specific producer population, more effective preparedness programs and messages can be developed by risk communicators. The purpose and objectives of this study determined Texas and Southwestern Cattle Raisers Association (TSCRA) members‘ perceptions of vulnerability to the Texas cattle industry, perceived emergency preparedness level, barriers to adoption of protective actions, and sources of animal health information. This study targeted 7,661 members of the TSCRA. An online survey questionnaire developed from previous research with similar populations allowed TSCRA members to respond to questions related to the objective of this study. A representative sample of TSCRA members from Texas, Oklahoma, and New Mexico responded to the survey. Recognizing susceptibility to biological hazards, TSCRA members identified high levels of perceived trust and reliability in local veterinarians as a source of information, consistent with previous studies. Although the majority of members reported they did not have a biosecurity plan implemented on their operations, they did recognize the necessity of preventative practices. TSCRA members were neutral on all barriers to adoption of protective actions; however, the barrier "lack of information" was rated higher by means as a barrier to adoption of protective actions. When investigating differences among noncommercial and commercial operations managed by TSCRA members, no statistical differences were identified in this study. However, when investigating differences among TSCRA members and number of cattle managed, a weak positive correlation was identified for perception of hazard by threat in relation to more animals managed. Findings of this study confirmed sources stating that the agriculture and food infrastructure is vulnerable to biological hazards as perceived by livestock owners (Motes, 2007; Spellman, 2008). Ashlock (2006) and Riley (2007) found similar perspectives of vulnerability among Oklahoma and Kansas producers further strengthening the need to protect the agriculture and food critical infrastructure as outlined by Homeland Security Presidential Directive – 9 (HSPD-9, 2004). Since it was determined that veterinarians are perceived to be the most reliable and trustworthy source of information by TSCRA members, local opinion leaders, such as veterinarians, should engage in train-the-trainer programs to ensure a consistent risk communication message is being disseminated.

This thesis provides a case study of the Government of Canada's former Office of Critical Infrastructure Protection and Emergency Preparedness (OCIPEP) through the lens of horizontal management (part of New Public Management theory). This study demonstrates that the effective use of horizontal management (horizontality) may reduce fragmentation occurring when the goal of critical infrastructure protection requires organizations to work cross-jurisdictionally and in partnerships. This need to collaborate is due to the ownership problem: over 85 per cent of Canada's critical infrastructure is owned by organizations other than the federal government. Research methods include a background survey of literature on critical infrastructure protection, horizontal management and horizontality, and new public management; and interviews using a snowball sample of eight subjects who held various positions within OCIPEP to better understand what the organizational structure appeared to be from within the organization. The research concludes that OCIPEP was not given the resources necessary to successfully fulfil its mandate. Results include the need for administrative and managerial support for horizontal endeavours, to encourage a "cultural context" of horizontality, as there are many organizational barriers to successfully using horizontality and collaborative methods. There were areas of success for OCIPEP, but more areas of weakness. Recommendations include additional study of the organization, a shift into a better-supported organization (which was accomplished with OCIPEP's inclusion into Public Safety and Emergency Preparedness Canada), and clear delineation of roles between the Government of Canada and the owners of the critical infrastructure.
