Résumé :

Following the tragic shootings in Newtown (Connecticut), Aurora (Colorado), Isla Vista (California) and others, increased national attention has focused on the relationship between mental illness and gun violence. While some have called for enhanced regulation of firearm possession by persons with mental illness, others have argued that such actions would be ineffective and enhance stigma associated with mental illness while discouraging treatment seeking.

Résumé :

Consensus is growing on the need to investigate the joint impact of neighborhood-level social factors and environmental hazards on respiratory health. This study used latent profile analysis (LPA) to empirically identify distinct neighborhood subtypes according to a clustering of social factors and environmental hazards, and to examine whether those subtypes are associated with lung function. The study included 182 low-income participants who were enrolled in the Colorado Home Energy Efficiency and Respiratory Health (CHEER) study during the years 2015–2017. Distinct neighborhood typologies were identified based on analyses of 632 census tracts in the Denver-Metro and Front Range area of Colorado; neighborhood characteristics used to identify typologies included green space, traffic-related air pollution, violent and property crime, racial/ethnic composition, and socioeconomic status (SES). Generalized estimating equations were used to examine the association between neighborhood typology and lung function. We found four distinct neighborhood typologies and provide evidence that these social and environmental aspects of neighborhoods cluster along lines of advantage/disadvantage. We provide suggestive evidence of a double jeopardy situation where low-income populations living in disadvantaged neighborhoods may have decreased lung function. Using LPA with social and environmental characteristics may help to identify meaningful neighborhood subtypes and inform research on the mechanisms by which neighborhoods influence health.

Résumé :

Since 1991, over half the states have enacted laws that restrict or prohibit insurers’ use of genetic information in pricing, issuing, or structuring health insurance. Wisconsin was the first state to do so, in 1991, followed by Ohio in 1993, California and Colorado in 1994, and then several more states a year in each of the next five years. Similar legislation has been pending in Congress for several years. Also, a 1996 federal law known as the Health Insurance Portability and Accountability Act (HIPAA) prohibits group health insurers from applying “preexisting condition” exclusions to genetic conditions that are indicated solely by genetic tests and not by any actual symptoms.

Résumé :

AbstractMedical aid in dying (MAiD), despite being legal in many jurisdictions, remains controversial ethically. Existing surveys of physicians’ perceptions of MAiD tend to focus on the legal or moral permissibility of MAiD in general. Using a novel sampling strategy, we surveyed physicians likely to have engaged in MAiD-related activities in Colorado to assess their attitudes toward contemporary ethical issues in MAiD.

Résumé :

Two aspects of ecosystem health in the Colorado River delta were investigated as part of the present dissertation. The following is a summary of the most important findings: Contaminants of natural origin (e.g. selenium) and anthropogenic activities (e.g. pesticides) represent a potential threat for humans and wildlife in the Colorado River delta. Fourteen locations were sampled for bottom material and biota from March 1998 to April 2000. Concentrations of selenium in bottom material ranged from 0.6-5.0 μg/g. Concentrations of selenium in biota ranged from 0.5-18.3 μg/g, 23% of these samples exceeded the toxic threshold where reproductive impairment in birds from dietary exposure is reported. Concentrations of DDE exceeded the lower critical dietary level for sensitive species in 30% of biota samples. No clear relationship could be found between the concentration of Se in bottom material and the concentration of Se in fish. Nevertheless, smaller Se concentrations in biota were found at sites that had an outflow and exposure or physical disturbance of the bottom material was uncommon. Greater concentrations of Se in biota were found at sites with strongly reducing conditions, no output, and subsequent periods of drying and flooding or dredging activities, and at sites that received water directly from the Colorado River. The southwestern willow flycatcher (Empidonax traillii extimus ) is an endangered neotropical migrant with only 300-500 breeding pairs. The objective of the second study was to determine the presence/absence of this bird in the Colorado River delta. Surveys were conducted from June to July, 1999 and from May to June, 2000 using an audio tape of this subspecies' songs to elicit responses. We detected a total of 50 willow flycatchers in the Colorado River delta in the months of May to June. None were detected in July, thus, the birds were most likely migrants. Restoration of the intensively used stopover sites of the Colorado River delta appears to be essential for the overall recovery of this subspecies. Additionally, we propose a possible willow flycatcher summer migratory route throughout the series of coastal estuaries found adjacent to the coast of Sonora.

Résumé :

The Rocky Flats Environmental Technology Site (EPA Superfund site near Denver, Colorado) produced plutonium components for nuclear weapons for the U.S. defense program. The facility shut down in 1989 and clean up began in 1992. To ensure safe remediation of inactive nuclear sites, site owners have begun to consult stakeholders more widely in recent years. The closure of Rocky Flats aimed to set the standard for stakeholder involvement in doing the work safely, complying with regulations/standards, in a cost-effective manner. We have studied, using ethnographic methods, the extent to which workers at Rocky Flats were involved in communication and decision making strategies. Our results point out that workers can have perceptions of the site remediation process that differ from management and even other workers and that a significant number of workers questioned the commitment by management to engage the worker as stakeholder. The most effective remediation efforts should involve careful consideration of the insights and observations of all workers, particularly those who face immediate and high-level health and safety risks.

Résumé :

The Rocky Flats Environmental Technology Site is a former nuclear weapons production facility owned by the U.S. Department of Energy (DOE). Located in central Colorado near Denver, the facility produced nuclear and non-nuclear components for weapons from 1953 to 1989. During this period, Rocky Flats grew to more than 800 facilities and structures situated on 2,500 hectares. Production activities and processes contaminated a number of facilities, soil, groundwater and surface water with radioactive and hazardous materials. In 1989, almost all radioactive weapons component production activities at Rocky Flats were suspended due to safety and environmental concerns related to operations, and the site was placed on the U.S. Environmental Protection Agency’s National Priorities List (also known as the Superfund list). In 1992, the nuclear weapons production role at Rocky Flats officially ended and the mission changed from weapons production to one of risk reduction. In 1995, Kaiser-Hill, LLC (Kaiser-Hill) was awarded a five-year contract to reduce the urgent health and safety risks at the site, as well as begin the cleanup. At that time, the U.S. government estimated that it would cost more than $36 billion and take more than 70 years to cleanup and close Rocky Flats. Beginning in the summer of 1995, Kaiser-Hill developed a series of strategic planning models which demonstrated that accelerated cleanup of the site could be achieved while dramatically reducing cleanup costs. Within a few years, Kaiser-Hill developed a cleanup plan or lifecycle baseline that described how cleanup could be accomplished by 2010 for about $7.3 billion. Additionally, between 1995 and 2000, Kaiser-Hill made significant progress toward stabilizing special nuclear materials, cleaning up environmental contamination, demolishing buildings and shipping radioactive and hazardous waste for disposal. This initial contract was completed for approximately $2.8 billion. In January 2000, based its record of successes, Kaiser-Hill was awarded DOE’s first “closure contract” to close the site no later than December 2006, at a target cost of $3.96 billion. To date, some of the key enablers of the accelerated closure project concept and successful closure project execution include: • Shared vision of the end state; • Flexible, consultative regulatory agreement; • Credible project plan and robust project management systems; • Closure contract; • Empowered and motivated workforce; • Commitment to safety; • Closure-enhancing technologies. The scope of the closure project encompasses the following key completion metrics: • Disposition of 21 metric tons of weapons-grade nuclear materials; • Treatment of more than 100 metric tons of high-content plutonium wastes called residues; • Processing of 30,000 liters of plutonium and enriched uranium solutions; • Demolition of more than 800 facilities and structures totaling more that 325,000 square meters — many of which are contaminated with radioactive and/or hazardous materials; • Offsite shipment of more than 250,000 cubic meters of radioactive waste; • Disposition of approximately 370 environmental sites.

Résumé :

Ongoing experimental work has been underway at selected nuclear sites in the Russian State Atomic Energy Corporation (ROSATOM) during the past two years to determine the effectiveness, reliability, application and acceptability of high technology polymers for liquid radioactive waste solidification. The long term project is funded by the U.S. Department of Energy’s Initiatives for Proliferation Prevention (IPP) program. IPP was established in 1994 as a non-proliferation program of DOE / National Nuclear Security Administration and receives its funding each year through Congressional appropriation. The objectives of IPP are: • To engage former Soviet nuclear weapons scientists, engineers and technicians, currently or formerly involved with weapons of mass destruction, in peaceful and sustainable commercial activities. • To identify non-military, commercial applications for former Soviet institute technologies through cooperative projects among former Soviet weapons scientists, U.S. national laboratories and U.S. industry. • To create new technology sources and to provide business opportunities for U.S. companies, while offering commercial opportunities and meaningful employment for former weapons scientists. Argonne National Laboratory provides management oversight for this project. More than 60 former weapons scientists are engaged in this project. With the project moving toward its conclusion in 2012, the emphasis is now on expanding the experimental work to include the sub-sites of Seversk (SCC), Zheleznogorsk (MCC) located in Siberia and Gatchyna (KRI) and applying the polymer technology to actual problematic waste streams as well as to evaluate the prospects for new applications, beyond their current use in the nuclear waste treatment field. Work to date includes over the solidification of over 80 waste streams for the purpose of evaluating all aspects of the polymer’s effectiveness with LLW and ILW complex waste. Waste stream compositions include oil, aqueous, acidic and basic solutions with heavy metals, oil sludge, spent extractants, decontamination solutions, salt sludge, TBP and other complex waste streams. Extensive irradiation evaluation (up to 270 million rad), stability and leach studies, evaporation and absorption capacity tests and gas generation experimentation on tri-butyl phosphate (TBP) waste have been examined. The extensive evaluation of the polymer technology by the lead group, V.G. Khlopin Radium Institute, has resulted in significant discussion about its possible use within the ROSATOM network. At present the focus of work is with its application to legacy LLW and ILW waste streams that exist in a variety of sectors that include power plants, research institutes, weapons sites, submarine decommissioning and many others. As is the case in most countries, new waste treatment technologies first must be verified by the waste generator, and secondly, approved for use by the government regulators responsible for final storage. The polymer technology is the first foreign sorbent product to enter Russia for radioactive waste treatment so it must receive ROSATOM certification by undergoing irradiation, fire / safety and health / safety testing. Experimental work to date has validated the effectiveness of the polymer technology and today the project team is evaluating criteria for final acceptance of the waste form by ROSATOM. The paper will illustrate results of the various experiments that include irradiation of actual solidified samples, gas generation of irradiated samples, chemical stability (cesium leach rate) and thermal stability, oil and aqueous waste stream solidification examples, and volume reduction test data that will determine cost benefits to the waste generator. Throughout the course of this work, it is apparent that the polymer technology is selective in nature; however, it can have broad applicability to problematic waste streams. One such application is the separation and selective recovery of trans-plutonium elements and rare earth elements from standard solutions. Another application is the use of polymers at sites where radioactive liquids are accidently emitted from operations, thus causing the risk of environmental contamination.
