Comparison of laboratory protocols for yielding improved estimates of hearing protection in field performance for use in standards development
Federal law requires hearing protection device (HPD) manufacturers to provide attenuation ratings for use in estimating workers’ protection levels. These ratings, which are laboratory obtained, typically overestimate the actual protection levels achieved in the workplace. This research investigated …

The battle for policy space : strategic advantages of a human rights approach in international intellectual property negotiations
… from which society will benefit. The strength of protection awarded to patented products is a policy decision, allowing states to balance the monopoly rights of patent-owners against the inherent social costs of monopoly protection. The effective policy space within which states may establish …

Three Essays on Crop Insurance: RMA's Rules and Participation, and Perceptions
… on the performance, participation, and risk protection level of actual producer history (APH) insurance. The second and third papers examined the presence of behavioral biases, such as miscalibration and better-than-average (BTA) effect in farmers’ perceptions, and related these biases to the …

The effectiveness of Table Mountain National Park Marine Protected Area in the conservation of rocky shore biodiversity
… and (2) community composition, between these two levels of protection. Some clear patterns emerged. Firstly, notake areas had significantly greater densities of the commonly harvested limpets Cymbula granatina, C. oculus and Scutellastra argenvillei, most obviously on sandstone ledges where …

Combating Corrosion and Monitoring Microgrids on Coast Guard Patrol Boats
… (FRCs). This thesis investigates hybrid cathodic protection strategies combining impressed current cathodic protection (ICCP) systems and sacrificial zinc anodes to combat corrosion on such vessels. Observing over 550 cumulative months of ICCP system data across 46 FRCs, this thesis identifies …

When all information is not created equal
… important, thus aiming to provide a uniform protection to all information. However, this homogeneous view of information is not suitable for a variety of modern-day communication scenarios such as wireless and sensor networks, video transmission, interactive systems, and control applications. …

Psychophysical investigation of the real-ear attenuation of hearing protection devices under different sound-field diffusivity conditions
… consensus standards governing hearing protection device (HPD) attenuation testing specify the use of a diffuse sound field to ensure the sound field remains uniform and random-incidence in an envelope about the subject’s head (ANSI, 1974; ANSI, 1984; British BSI 5108:1983; Canadian CSA …

Advanced Receiver Autonomous Integrity Monitoring for Multi-Constellation GNSS and LEO-Augmented GNSS
… ability to provide navigation guarantees are protection levels, i.e., high confidence bounds on the positioning error, including the horizontal protection level (HPL) and the vertical protection level (VPL). This dissertation advances the state of ARAIM and complementary satellite navigation …

Essays in Environmental Economics
… Reynaert, and Tristan Grupp, I turn to land protection policy as a tool of spatial organization for economic and environmental activity. The European Union designates 26\% of its landmass as a protected area, limiting economic development to favor biodiversity. We use the staggered …

Development and testing of recombinant B. abortus RB51 vaccine strains carrying M. tuberculosis protective antigens
… proteins Ag85B and ESAT6, a significant level of protection (1 log reduction) compared to the PBS vaccinated group was achieved. The protection levels conferred by this vaccination strategy was similar to that conferred by BCG vaccine. In conclusion, we have shown that recombinant RB51 strains …

Integrity and attack-resilience of GPS-based positioning and timing: a Bayesian and measurement fusion approach
… To monitor integrity, we estimate vertical protection levels using a Bayesian approach. We further generate GPS datasets simulating open, semi-urban, and urban environments for validating DP with multiple receivers. For mitigating GSAs for timing, we design static and dynamic state …

Enhancing the conservation of freshwater biodiversity through improved freshwater conservation planning techniques
… they provide. These may take the form of formal protection but also need to include less restrictive mechanisms, such as implementing integrated catchment management and environmental water requirements. Systematic conservation planning provides a strategic and scientifically defensible framework …
