Mercury Hall Interview
No full textMercury Hall (B.A. 1998, M.A. 2003) was interviewed by Ruth Demissie via the Zoom internet-based video conferencing software on March 12, 2021. Mr. Hall was born and raised in Waco, Texas. While in school in Waco, he played four sports: football, track, baseball, and basketball, and excelled in all four. He received multiple sports scholarships, but ultimately selected SMU due to its location and opportunities to play sports other than football. As an undergraduate, Mr. Hall majored in psychology and participated in a casting call for the movie ''Any Given Sunday,'' in which he appeared as an extra. During his interview, he discusses his experiences on the SMU Mustangs football team and navigating microaggressions on a predominantly white campus. After graduating, he went on to study for his master's degree in Applied Economics, and was SMU's first Black recipient of that degree, for which he earned a History Maker award. At the time of the interview, Mr. Hall operated his own company, MercuryUniverse, a platform intended for aspiring college athletes to serve as a recruiting tool while also promoting themselves to coaches and agents
Informal gold mining and mercury pollution in Brazil
Get PDFThe Amazon region has been responsible for a major share of Brazilian gold production in recent years. The region has witnessed a sizable gold rush comparable only to the California gold rush last century. The gold rush has spawned a powerful informal mining sector and has attracted many people - some who have come to the region in search of wealth and some who were already there but were displaced from other, unsuccessful economicactivities. What these people encounter at the mining sites are dreadful living and working conditions. Gold mining also causes substantial environmental problems, which may persist whether gold deposits do or not. The author discusses the environmental effects of gold mining in the region, focusing on mercury pollution. Mercury, an important input in gold extraction, is being discharged into the atmosphere and the rivers at alarming rates. The environmental costs of the present extraction, is being discharged into the atmosphere and the rivers at alarming rates. The environmental costs of the present extraction technology will be faced primarily by future generations, because of natural chemical processes. Although removing the mercury already discharged from the Amazonian environment may be an enormous task, at least future discharges should be curtailed through the use of appropriate technology, environmental education, and a combination of command and control measures and market-based incentives. The author describes the gold extraction process and the extent of mercury use and contamination. He analyzes key elements of the environmental problem, especially the informal miner and the fish economy. Finally, he suggests a combination of command and control regulations and market-based incentives adapted to the informal gold mining economic environment. He emphasizes the need for an education campaign about the perils of using mercury and the availability of more appropriate, and inexpensive, alternative extraction technologies.Mining&Extractive Industry (Non-Energy),Montreal Protocol,Water and Industry,Coastal and Marine Resources,Primary Metals
Students getting drinks inside the Cheney Hall
No full textThis is a black and white photograph that shows the inside of Springfield College's Cheney dining hall. People sitting at tables and eating can be seen on the far end of the hall, and there are students getting drinks at the beverage stations close to where the photograph was taken. The photograph was taken behind a trailer that carries utensils, which is visible on the bottom of the photograph.Cheney Hall opened on April 1, 1968, replacing the existing cafeteria, Woods Hall, and increasing the serving capacity from 300 to 800 per sitting. The new facility was dedicated on June 15, 1968 to Ralph L. Cheney, class of 1901, and R. William Cheney, class of 1933, a father and son who were very influential at Springfield College. The 26,500 sq. ft. facility has a semi-circular wall curving outward at the front, which adds 45’ of depth to the building. Originally the building included a covered portico following this curve, which provided shade and shelter to students; however, in 2005 the portico was enclosed for extra seating. In addition, there are two separate and smaller dining areas, which can seat up to 110 extra people. Today, these rooms are called Cheney rooms A & B and are used by faculty and staff to hold special functions. In an attempt to keep up with other colleges, Springfield College and Aramark, the school’s food service company, made renovations to the dining hall in 2004. These changes included a more expansive seating area with two different levels of seating and various stations with different types of food. The renovations also allowed students to pay for a meal upon entry and eat as little, or as much, as desired.On the back of the photograph, there is a stamp that says "Mercury Studio ALLEN ST. HAMPDEN MASS. JO 6-3951", indicating the creator of the photograph
Binding-Time Analysis for Mercury
Get PDFIn this work, we develop a binding-time analysis for the logic programming language Mercury. We introduce a precise domain of binding-times, based on the type information available in Mercury programs, that allows the analyser to reason with partially static data structures. The analysis is polyvariant, and deals with the module structure and higher-order capabilities of Mercury programs.status: Publishe
Designing Environmental Policy: Lessons from the Regulation of Mercury Emissions
Get PDFIn its waning days, the Clinton administration decided that it was appropriate to regulate mercury emissions from power plants. The incoming Bush administration had to decide how best to regulate these emissions. The Bush administration offered two approaches for regulating mercury emissions from power plants. The first was to establish uniform emission rates across utilities, as mandated by the 1990 Amendments. The second was to establish a cap on mercury emissions while allowing emissions trading in order to reduce the cost of achieving the goal. This paper presents the first cost-benefit analysis of this issue that takes account of IQ benefits. We find that the benefits of the mercury regulation are likely to fall short of the cost. This assessment is based on a number of assumptions that are highly uncertain. The finding of negative net benefits is robust to many, though not all, reasonable variations in the model assumptions. We also find that the emissions trading proposal is roughly $15 billion less expensive than the command-and-control proposal.
Summertime elemental mercury exchange of temperate grasslands on an ecosystem-scale
Get PDFIn order to estimate the air-surface mercury exchange of grasslands in temperate climate regions, fluxes of gaseous elemental mercury (GEM) were measured at two sites in Switzerland and one in Austria during summer 2006. Two classic micrometeorological methods (aerodynamic and modified Bowen ratio) have been applied to estimate net GEM exchange rates and to determine the response of the GEM flux to changes in environmental conditions (e. g. heavy rain, summer ozone) on an ecosystem-scale. Both methods proved to be appropriate to estimate fluxes on time scales of a few hours and longer. Average dry deposition rates up to 4.3 ng m(-2) h(-1) and mean deposition velocities up to 0.10 cm s(-1) were measured, which indicates that during the active vegetation period temperate grasslands are a small net sink for atmospheric mercury. With increasing ozone concentrations depletion of GEM was observed, but could not be quantified from the flux signal. Night-time deposition fluxes of GEM were measured and seem to be the result of mercury co-deposition with condensing water. Effects of grass cuts could also be observed, but were of minor magnitude

Hickory Hall Science Classroom (back of room)
No full textThis black and white photograph displays an old science classroom inside Springfield College's Hickory Hall. Hickory Hall was originally known as Bemis Hall. Depicted are lab benches, chairs, a projector on a wheeled cart, cabinets in the back of the classroom, as well as hygiene and safety items such as micro-wipes and a fire extinguisher.Hickory Hall, previously known as Bemis Hall, was the final item funded by Springfield College’s 7.3 million dollar Capital Campaign in 1974. It was located adjacent to Schoo Hall, known today as the Schoo-Bemis Science Center. Construction began in April, 1974 and the building was opened for full use in April of 1975. The new building, with a unique circular structure, was used as a life sciences building. Some innovative features included, moveable walls in lab areas, “dustless” marker boards, an interior ramp allowing handicapped access, faculty offices designed to accommodate seminar groups, and laboratories designed for specific areas of interest such as microscopy, physiology, plant biology, microbiology and genetics.
Under the leadership of SC President Richard B. Flynn a complete renovation of Bemis Hall was undertaken. The new design focused on creating technology enhanced classrooms, replacing the life sciences laboratories and classrooms with an 80-seat semi-circular lecture hall and seven new classrooms. The newly renovated Hall was dedicated on September 27, 2007 along with the Schoo-Bemis Science Center (renovated at the same time). The Bemis name, along with the life science focus of the Hall, was moved to the new state-of-the-art Schoo-Bemis Science Center. Interestingly enough, Hickory Hall was actually supposed to be a place-holder name, being the name of the street that used to pass through the center of campus

A Cross-Sectional Survey on Knowledge and Perceptions of Health Risks Associated with Arsenic and Mercury Contamination from Artisanal Gold mining in Tanzania.
Get PDFAn estimated 0.5 to 1.5 million informal miners, of whom 30-50% are women, rely on artisanal mining for their livelihood in Tanzania. Mercury, used in the processing gold ore, and arsenic, which is a constituent of some ores, are common occupational exposures that frequently result in widespread environmental contamination. Frequently, the mining activities are conducted haphazardly without regard for environmental, occupational, or community exposure. The primary objective of this study was to assess community risk knowledge and perception of potential mercury and arsenic toxicity and/or exposure from artisanal gold mining in Rwamagasa in northwestern Tanzania. A cross-sectional survey of respondents in five sub-villages in the Rwamagasa Village located in Geita District in northwestern Tanzania near Lake Victoria was conducted. This area has a history of artisanal gold mining and many of the population continue to work as miners. Using a clustered random selection approach for recruitment, a total of 160 individuals over 18 years of age completed a structured interview. The interviews revealed wide variations in knowledge and risk perceptions concerning mercury and arsenic exposure, with 40.6% (n=65) and 89.4% (n=143) not aware of the health effects of mercury and arsenic exposure respectively. Males were significantly more knowledgeable (n=59, 36.9%) than females (n=36, 22.5%) with regard to mercury (x²=3.99, p<0.05). An individual's occupation category was associated with level of knowledge (x²=22.82, p=<0.001). Individuals involved in mining (n=63, 73.2%) were more knowledgeable about the negative health effects of mercury than individuals in other occupations. Of the few individuals (n=17, 10.6%) who knew about arsenic toxicity, the majority (n=10, 58.8%) were miners. The knowledge of individuals living in Rwamagasa, Tanzania, an area with a history of artisanal gold mining, varied widely with regard to the health hazards of mercury and arsenic. In these communities there was limited awareness of the threats to health associated with exposure to mercury and arsenic. This lack of knowledge, combined with minimal environmental monitoring and controlled waste management practices, highlights the need for health education, surveillance, and policy changes
