This research estimates the achievable CO2 emissions reductions for a medium sized office building located in Salt Lake City, Utah. Four strategies that required minor retrofits or changes to a building’s operational controls were considered: automatic window shading, changes in window construction, lighting intensity, and temperature setpoint adjustment. Since 70% of energy consumed by the building sector is for heating, cooling and lighting, the methods introduced were targeted to reduce these sources of demand. The model building used was selected from the U.S. DOE’s commercial reference buildings. The simulations were run using the DOE’s EnergyPlus building energy modeling software and a TMY3 weather data file for Salt Lake City. The effect of these possible building changes on energy consumption and the CO2 emissions resulting from the production of this energy were examined. The impact of the automatic window shade was the lowest of the strategies considered with a 1% reduction in GHG emissions. This is likely the result of a low solar irradiation area to building volume ratio and should be explored for smaller residential and commercial buildings. Window construction was more promising with GHG emissions reductions between 2% and 6%. Lighting strategies and altered temperature set points demonstrated GHG emissions reduction of up to 15%. This research establishes a technique to evaluate building emissions reductions with respect to location, building construction, and operation.

The Impact

Climate policy requires substantial reductions in long-term greenhouse gas (GHG) emissions, including in the transportation sector. As passenger cars are one of the dominant CO2 emitters in the transport sector, governments and the automobile industry have implemented various countermeasures, including decarbonization of fuels, more energy efficient vehicles, and transport demand management. However, the total impact of these measures in the long term remains unclear. This study aims to clarify the CO2 emissions reductions from passenger cars by 2050 in 1727 municipalities in Japan under a declining population. To estimate CO2 emissions, we model travel behavior and traffic situations reflecting the regional conditions of the municipalities, including population density and accessibility to public transport for the base year 2010. Assuming plausible scenarios for future populations and automobile technologies, we estimate CO2 emissions from passenger cars. We estimate that CO2 emissions will decline by 64–70% between 2010 and 2050, with automobile technologies playing the largest role. We find that the impact of urban compaction is marginal at the national level but varies by municipality. These results imply that, given regional variations, all countermeasures, including technology and demand management, must be used to achieve the long-term target of CO2 emissions reductions.

Winter outdoor recreation opportunities in Utah are directly impacted by the effects of climate change and deteriorating air quality. We examine the influences of daily weather conditions and air quality on winter use of two prominent Utah canyons located just outside Salt Lake City-Big and Little Cottonwood Canyons. Daily weather data were collected both within the canyons and in Salt Lake City; daily air quality data were collected for just Salt Lake City. We hypothesized that desirable weather within the canyons (i.e., cooler temperatures, more snowfall, and deeper snow depths) serves as a “pull” factor, positively influencing the volume of traffic. We also hypothesized that poor air quality within the city acts as a “push” factor on individuals’ travel behavior, this too would positively influence the volume of traffic up the canyons. We used a panel time-series regression model to determine the influence of both these “push” and “pull” factors on use of the canyons during the winter months. Our results revealed that, as expected, cooler temperatures and greater amounts of snow in the canyons, as well as poorer air quality in the city, have a positive and significant influence on winter canyon use. These findings suggest that warmer winter temperatures, as well as deteriorating air quality in the city, may have substantial impacts on Utah’s outdoor recreation economy.

The Impact

Since the early 2000s, there has been a groundswell of research on terrorism and sports mega-events, including investigations into the impact of ‘9/11’ on fear and risk management strategies at high profile sports events. In this article, we re-examine the case of the Salt Lake City Winter Games of 2002 around Baudrillard’s (1995) concept of the ‘non-event’. We compare the (largely British and North American) mass mediation and discursive framing of terrorism at the 2002 Games with subsequent discourses interwoven into accounts of terrorism, fear and security at the 2004 Summer Olympic Games in Athens and the 2006 Winter Olympic Games in Turin. Of principal interest is the global framing of sports mega-events as targets of terrorism and the ways in which such events become fabricated zones of risk. To understand why there is a lingering media construction of the sports mega-event as an imagined target (and, in many ways, pre-constructed victim) of terrorism, we draw centrally on Baudrillard’s work (1995, 2001, 2002a, 2002b). Specifically, we employ Baudrillard’s concepts of the hyperreal and the non-event as a means of exploring terrorism’s relationship with sport, and the potential usage of such theoretical ideas in the sociology of sport and physical culture more broadly.

The Impact

AbstractWriting in Nationalist revolutionaries in Ireland, 1858–1928, Tom Garvin observed that ‘well over 40 per cent, perhaps 50 per cent, had lived outside Ireland for considerable periods … foreign experience was very important in the development of the leaders’. The impact of ‘foreign experience’ on leading nationalist revolutionaries, this article submits, pace Garvin, could have proved influential in the development of the Irish Revolution more widely. Between June 1919 and December 1920, Éamon de Valera toured the United States. From New York City to Salt Lake City, Alabama to Montana, the self-proclaimed president of the Irish republic addressed ‘Ireland’ in hundreds of interviews and speeches. Of these myriad public statements, his Cuban missive, notably, crossed national boundaries. Comparing Ireland's geo-strategic relationship with Great Britain to that of Cuba and the United States, de Valera's argument for an independent Irish republic was made in the Americas. How did de Valera's movement across the U.S. alter his political views of Ireland? How were presentations of de Valera's ‘Cuban policy’ mediated across the ‘Irish world’? How did discourse on the Monroe Doctrine inform Anglo-Irish negotiations between Truce and Treaty? Exploring de Valera's ‘Cuban policy’ as global case study, this article concludes, ultimately, can shift the historiographical significance of ‘foreign experience’ from nationalist revolutionaries in Ireland to the flows and circulation of transnational revolution.

Abstract BACKGROUND: Rapid and accurate diagnostic tools are needed for appropriate management of infectious diarrhea. METHODS: We evaluated the impact of the introduction of rapid multiplex PCR testing using the FilmArray gastrointestinal (GI) panel (BioFire Diagnostics, LLC, Salt Lake City, UT) at our institution, and compared the results to those of standard stool cultures. RESULTS: The most common pathogens detected by the FilmArray GI panel were Clostridium difficile (55.0%), Campylobacter species (20.9%), Salmonella species (12.4%), and Shigella/EIEC species (12.4%). Rates of reproducibility in stool culture for these pathogens ranged from 56.3% to 77.8%. Co-detection of two or more organisms was common (24.2%), most commonly involving EPEC, EAEC, ETEC, and STEC. The time from arrival in the Emergency Department to discharge or admission to the hospital was unchanged after the introduction of FilmArray GI panel, but length of hospital stay was shorter (3 vs. 7.5 days, p=0.0002) for the FilmArray group. The time to empiric antibiotics did not differ significantly, but optimal antibiotics were started earlier after introduction of the FilmArray GI panel (hospital day 1 vs. 2, p<0.0001). More patients were discharged without antibiotics after introduction of the FilmArray GI panel (14.0% vs. 4.5%; p<0.001). CONCLUSION: Our results demonstrate that the FilmArray GI panel is an important tool for improving both patient care and antibiotic stewardship, despite the tendency for positive results with multiple pathogens.

ABSTRACT We aimed to detect the etiological agents of acute diarrhea by a molecular gastrointestinal pathogen test (MGPT) and to assess the impact of MGPT on antimicrobial stewardship programs (ASP). This is a prospective observational study and was conducted between 1 January 2015 and 30 June 2017. We included consequent patients who had acute diarrhea. At the end of 2015, we implemented ASP in acute diarrhea cases and compared the outcomes in the pre-ASP and post-ASP periods. An FDA-cleared multiplexed gastrointestinal PCR panel system, the BioFire FilmArray (Idaho Technology, Salt Lake City, UT), which detects 20 pathogens in stool, was used. In 499 out of 699 patients (71%), at least one pathogen was detected. Among 314 adults with positive MGPT, 101 (32%) enteropathogenic Escherichia coli (EPEC), 71 (23%) enteroaggregative E. coli (EAEC), 68 (22%) enterotoxigenic E. coli (ETEC), 55 (18%) Shiga toxin-producing E. coli (STEC) (17%) Norovirus , 48 (15%) Campylobacter , 21 (7%) Salmonella , and 20 (6%) Clostridium difficile strains were detected. Among 185 children, 55 (30%) EPEC, 37 (20%) C. difficile , 32 (17%) Norovirus , 29 (16%) EAEC, 22 (12%) STEC, 21 (11%) ETEC, 21 (11%) Campylobacter , 20 (11%) Salmonella , and 16 (5%) Rotavirus strains were detected. Inappropriate antibiotic use decreased in the post-ASP period compared with the pre-ASP period among inpatients (42.9% and 25.8%, respectively; P = 0.023). Using MGPT in clinical practice significantly decreased the unnecessary use of antibiotics. Detection of high rates of C. difficile in children and Salmonella spp., as well as relatively high rates of Campylobacter spp., which were hard to isolate by routine stool culture, were remarkable.
