The Search For Microbial Martian Life And American Buddhist Ethics, Daniel S. Capper

Faculty Publications

Multiple searches hunt for extraterrestrial life, yet the ethics of such searches in terms of fossil and possible extant life on Mars have not been sufficiently delineated. In response, in this essay I propose a tripartite ethic for searches for microbial Martian life that consists of default nonharm toward potential living beings, default nonharm to the habitats of potential living beings, but also responsible, restrained scientific harvesting of some microbes in limited transgression of these default nonharm modes. Although this multifaceted ethic remains secular and hence adaptable to space research settings, it arises from both a qualitative analysis of authoritative …

Improving Access To Clean Water In Rural Ecuador: The Connection Between Willingness To Pay And Population Health, Micalea Leaska

Capstone Collection

Climate change is affecting social and environmental determinants of health through access to safe drinking water, safely managed sanitation systems, and access to health care services and the ability for individuals to break free from unsuitable circumstances. Ecological disturbances such as those caused by climate change can cause a shift in host vectors or a change in habitat that results in a greater likelihood of the pathogen coming in contact with humans. Water, sanitation, and hygiene (WASH) services and their accessibility to populations can directly impact a community’s vulnerability to diseases and limiting factors to increase economic growth. If rural …

An Assessment Of Fecal Water Contamination In The Absaroka-Beartooth Wilderness, Daniel Paul Pendergraph 5024527

Graduate Student Theses, Dissertations, & Professional Papers

Wilderness water sources are often defined as pristine or high quality due to the lack of point source pollution. Non-point source pollution from recreation to water resources can be extensive and is well-studied in protected areas globally. Bacterial contamination, specifically fecal bacteria, poses a significant threat to human health because of the risk for outbreaks of illness and disease. Water sources in designated Wilderness areas are particularly vulnerable to fecal water contamination due to high volume of backpackers and lack of backcountry waste facilities. To estimate the occurrence of fecal water contamination in Wilderness water resources, an exploratory analysis was …

Evaluation Of Ufp Number Concentrations Near A Natural Gas Transmissions Station, John M. Thornsbury

Graduate Theses, Dissertations, and Problem Reports

Identifying UFP number concentrations near a natural gas compressor station is key to understanding ambient exposures associated with the transmission station. Developing an atmospheric survey to characterize these concentrations was key in understanding ambient exposures. The aims of this study are to compare and contrast number concentrations taken in a hollow, near the transmission station to those of the background. From this, it would be possible to identify whether or not the compressor station was a contributing factor to peaks and spikes in number concentrations.

This study begins with a review of what UFPs are, how they react in different …
