Tourism is one of the largest industries in the world, and causes many cultural, environmental, and economic problems. In this thesis, I explore ethics in the field of tourism studies, and identify three ethical models used to discuss ethics in tourism, which are: business ethics, alternative tourism, and philosophical ethics....
At the macroscopic scale, we have pumps that use the classical laws of physics to move liquids at a well defined rate. In the microscopic world, physicists are exploring pumps that make use of quantum mechanical behavior to build analogous pumps for quantum particles. The importance of such “quantum pumps”...
The urban hydrology and hydraulics program, US EPA SWMM 5, has been coupled with a compartment model of a wastewater treatment plant (WWTP) in the system dynamics software, STELLA, to simulate the radiocesium pathway from urban catchment to the wastewater treatment sludge. Two literature case studies were re-examined. Firstly, a...
Current calls for prison abolition have been met with major public resistance.
It is time for movements for prison abolition to engage with these questions: How
have contemporary people of the United States come to accept mass incarceration and
the prison industrial complex, and, what is the impact? Using an...
Old-growth forests are structurally complex in both vertical and horizontal dimensions. This complexity arises from biological characteristics, typically branch and leaf structure, but also includes epiphytes with varying form and function. I characterized the biomass and species composition of epiphytes along the vertical axis of an old-growth Douglas-fir (Pseudotsuga menziesii)...
Efficient methods for simulating the substrate noise generated by complex synchronous and asynchronous digital logic circuits are presented. By simulating digital logic at the gate level, and precharacterizing the gates, the substrate noise generation can be predicted and used in a transistor level simulation of the sensitive analog blocks. This...
Hydrilla and Brazilian elodea are invasive aquatic plants that occupy freshwater habitats. While hydrilla is native to Asia, Africa, and eastern Australia, and Brazilian elodea is native to South America, both plants are invasive to North America. Because these plants are related and both have pointed green leaves that whorl...
The Red-Eared Slider, also called the red-eared terrapin, is an American breed of turtle widely spread across the USA, and is quickly becoming an invasive species in many parts of the world. It is also the most popular breed of pet turtle in the US and is widely kept as...
