Research on health effects of particulate matter (PM) has been a very active area in the last two decades. One plausible mechanism by which exposure to PM affects human health includes modification of autonomic endothelium function. Decreased endothelium activity causes heightened risks of cardiovascular disease. A human exposure chamber designed to conduct experiments to quantify diminished function of endothelium from short term exposure to PM is described. The chamber consists of two stages for containment and pre-treatment of PM and exposure of human subjects. Concentrations of CO, CO2, NO, NO2, O3, and PM2.5, are monitored and controlled in the exposure room. The PM used in the human exposure experiments was characterized chemically and morphologically. During January and February of 2009, chemical analysis of PM2.5 was done during inversion periods in Salt Lake City, UT. An Ambient Ion Monitor (AIM) was deployed to measure the concentrations of anions in both particulate and gas phases. The chemical data provided by AIM was complemented by measurements by the Department of Air Quality that included PM10, PM2.5, O3, NO, NO2, NH3 and CO. The goal of the study was to determine whether ammonia or nitric acid is the limiting reagent in formation of PM during inversions. Nitric acid is the limiting reagent. Concentrations of ammonia are an order of magnitude higher than nitric acid.

The influence of human activity on surrounding environments is an important field of research. With respect to aquatic settings, lacustrine deposits provide excellent proxies of environmental change since the sediment accumulates at a relatively constant rate, recording environmental change. This study employs isotopic, mineral, and chemical records from Farmington Bay freeze cores, in particular δ13C, δ15N, and 210Pb isotopes as well as phosphorus level fluctuation and trace metal analysis. In particular, 210Pb isotopes permit estimation of the age of sediment with depth and δ15N, δ13C, and concentration of P provides a record of changing nutrient sources and level of eutrophication. Results from 210Pb isotopes have allowed ages to be assigned to depths along the core dating back roughly 100 years at 30 cm. At this depth, a dramatic shift in the δ15N isotope is observed. Initial δ15N levels indicated a nutrient source related to agriculture. However, beginning around 100 years ago, the δ15N shows the main nutrient source for the bay became wastewater which correlates to the completion of a sewage canal in 1911 that began routing wastewater directly into the bay. Results have also shown a large rise in phosphorus levels beginning around 1970 which may be due to the construction of the automobile causeway that isolated Farmington Bay from the rest of the Great Salt Lake.

This thesis examines the Utah Nippo, its messages to Salt Lake City's Nikkei population, and draws out the paper's editorial themes intended for resident Utah Nikkei. The Utah Nippo was one of three Japanese-language newspapers that published during World War II and it was a voice for community leaders and editors who urged Salt Lake Nikkei to behave in certain ways that (they believed) would prove a certain loyal American identity. Such an identity was comprised of prescribed behaviors: supporting the government and war effort, attending patriotic activities, keeping a low social profile, and quietly enduring the fear and discrimination directed at them as Nikkei in the midst of a national war against Japan. The Utah Nippo painted the model minority stereotype during World War II, although scholars view it as a postwar concept imposed on Asian Americans. Although not entirely dictated by the Japanese American Citizens League, the newspaper content was influenced by the League's wartime campaigns for working with the U.S. government and behaving loyally. Nikkei in community leadership roles actively encouraged this image because it meant safety by assurance of Americanism. Individuals and editorials highlighted behaviors that helped or hurt the group image. The newspaper also focused on ending racism in the U.S. within Nikkei communities and as they resettled throughout the nation. While the Utah Nippo printed such sentiments, not all residents necessarily agreed with or did as the newspaper suggested, yet the articles indicated the identity that editors and leaders hoped to create. In light of the tenuous situation that Salt Lake Nikkei felt they lived in, it made sense for individuals to outwardly conform and incorporate the paper's behavioral guidelines in order to deflect suspicions over loyalty away from the group.

News directors fill, perhaps, one of the most difficult roles within the drama of the news room. In an environment where objectivity and trust are paramount, and where bias must be kept at an absolute minimum, the news director exists as the arbiter, balancing these journalistic ideals with the necessities for financial survival. This scenario presents a conflict, in which the news director must constantly balance the journalistic obligation to inform the public, with the managerial obligation to generate a profit. In an exploration of this conflict, I interviewed three news directors from KUTV, KSL, and KTVX within the Salt Lake City market, who each face different circumstances, but who each personify the conflict mentioned above. Each of these news directors place the most value on maintaining the quality of their news product, while still remaining conscious of the budget requirements set by corporate ownership. When push comes to shove, however, each news director interviewed for this study was of the opinion that news has to come first, even if it means going over budget. When addressing higher management in these over-budget situations, all three news directors tended to shift their conversation to the long-term perspective, reassuring their managers that costs (as a percentage) would drop over time, and revenues would increase. The sacrifice of news content for the sake of the budget was rare for all three news directors. Competition is seen as a way to better serve the community, long term, through increased revenue. Credibility is the balancing factor, keeping the business interests in check with the journalistic ideals.

The purpose of the study was to determine what degree of understanding third year graduates of the SLVN Seminary District had of the nature and mission of Christ.The study was composed of a random sample of 200 third year seminary graduates. Each participant answered a questionnaire designed to test his understanding of the nature and mission of Christ. The responses were tabulated and presented in written and illustrative form.The students met the minimum established standard of 75% in four of the five concepts which they were questioned concerning the nature of Christ. The students met the minimum established standard in five of the eight concepts testing their understanding of the mission of Christ.Overall comprehension of both the nature and mission of Christ were considered adequate as the students averaged 80% correct responses to all questions.

This study examines the demographic characteristics of household heads in Salt Lake City, Utah at three points in its history: 1850, 1860, and 1870. Data was compiled on population growth, nativity, sex, age, occupation, wealth, and persistence from the United States Census for those years.The data shows that between 1850 and 1870 the makeup of Salt Lake City household heads changed dramatically from predominately American-born to predominately foreign-born. This change in the nativity of household heads over time significantly influenced several demographic characteristics including the location of immigrant settlement, occupational tendencies, and a high level of stratification of real wealth.

This thesis is an historical archaeological project involving the classification and analysis of the ceramics found at Camp Floyd, a 19th century military site 40 miles southwest of Salt Lake City, Utah. United States military troops were dispatched to the Utah Territory to establish a Pony Express Station and an Overland Stage Trail, to assert federal authority in the Territories, and to end the ongoing conflict between the federal government and the Church of Jesus Christ of Latter Day Saints. The primary research question concerned the ceramic usage patterns at Camp Floyd as compared to other military sites and non-residential sites of the 19th century. The ceramic assemblage recovered from Camp Floyd was classified using Berge's classification system of historical ceramics. A sample from this collection was analyzed in order to assess social and economic differences between officers' and enlisted men.
