A major problem facing environmental managers is the necessity to effectively evaluate management alternatives. Traditional environmental assessments have emphasized the use of economic analyses. These approaches are often deficient due to difficulty in assigning dollar values to environmental systems and to social amenities. A more flexible decisionmaking model has been developed to analyze management options for coping with beach erosion problems at the Sandy Hook Unit of Gateway National Recreation Area in New Jersey. This model is comprised of decision-making variables which are formulated from a combination of environmental and management criteria, and it has an accept-reject format in which the management options are analyzed in terms of the variables. Through logical ordering of the insertion of the variables into the model, stepwise elimination of alternatives is possible. A hierarchy of variables is determined through estimating work required to complete an assessment of the alternatives for each variable. The assessment requiring the least work is performed first so that the more difficult evaluation will be limited to fewer alternatives. The application of this approach is illustrated with a case study in which beach protection alternatives were evaluated for the United States National Park Service.

CH2M HILL Plateau Remediation Company (CH2M HILL) is the U.S. Department of Energy (DOE) prime contractor responsible for the environmental cleanup of the Hanford Site Central Plateau. As part of this responsibility, the CH2M HILL is faced with the task of complying with thousands of environmental requirements which originate from over 200 federal, state, and local laws and regulations, DOE Orders, waste management and effluent discharge permits, Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) response and Resource Conservation and Recovery Act (RCRA) corrective action documents, and official regulatory agency correspondence. The challenge is to manage this vast number ofmore » requirements to ensure they are appropriately and effectively integrated into CH2M HILL operations. Ensuring compliance with a large number of environmental requirements relies on an organization’s ability to identify, evaluate, communicate, and verify those requirements. To ensure that compliance is maintained, all changes need to be tracked. The CH2M HILL identified that the existing system used to manage environmental requirements was difficult to maintain and that improvements should be made to increase functionality. CH2M HILL established an environmental requirements management procedure and tools to assure that all environmental requirements are effectively and efficiently managed. Having a complete and accurate set of environmental requirements applicable to CH2M HILL operations will promote a more efficient approach to: • Communicating requirements • Planning work • Maintaining work controls • Maintaining compliance« less

DIY Weights and Measures: Developing Your Own Calibration Methods Using Available Materials

NASA Astrophysics Data System (ADS)

Marchetto, P.

2017-12-01

In most cases, when a custom device is built, when an instrument arrives from the manufacturer, or when a piece of equipment is picked up from the store, it is assumed that it will just work, and that data from it will be completely reliable. This fundamental expectation by many scientists is completely unfounded. Between shipping, variable environmental conditions, and many other factors, sensing systems and instruments will be out of tolerance when used. In order to get them back in tolerance, or to at least find out what their uncertainties are, characterization is necessary. If adjustment to the device is possible, this is carried out and called a calibration. In this work, several ways of generating characterization and adjustment methods are discussed, with acoustic, hydraulic, and meteorological devices as examples.

This compendium of papers describes results of hydrologic monitoring and hydrologic and environmental studies completed by the U.S. Geological Survey (USGS) in Georgia during 2011–2013. The USGS addresses a wide variety of water issues in the State of Georgia working with local, State, and Federal partners. As the primary Federal science agency for water resource information, the USGS monitors the quantity and quality of water in the Nation’s rivers and aquifers, assesses the sources and fate of contaminants in aquatic systems, collects and analyzes data on aquatic ecosystems, develops tools to improve the application of hydrologic information, and ensures that its information and tools are available to all potential users. During 2011–2013, the USGS continued a long-term program of monitoring stream and groundwater resources, including flow, water quality, and water use. In addition, a variety of hydrologic and environmental studies were completed to assess water availability, hydrologic hazards, and the impact of development on water resources. Information on USGS activities in Georgia is available online at http://ga.water.usgs.gov/.

This study aims to systematically review available evidence from prospective cohort studies to identify intrapersonal, social environmental and physical environmental determinants of moderate-to-vigorous intensity physical activity (MVPA) among working-age women. Six databases were searched to identify all prospective cohort studies that reported on intrapersonal (e.g. self-efficacy and socioeconomic status [SES]), social (e.g. crime, area SES and social support) and/or physical (e.g. weather, work and recreation) environmental determinants of MVPA in working-age (mean 18-65 years) women. A qualitative synthesis including harvest plots was completed. CRD42014009750 RESULTS: Searching identified 17,387 potential articles; 97 were used in the analysis. The majority (n = 87 studies) reported on ≥1 intrapersonal determinant. Very few (n = 34) examined factors in the social or physical environments, and none looked at social policy. Positive and consistent influencers included higher self-efficacy (n = 18/23), self-rated health (n = 8/13) and intentions (n = 10/11) and perceived behavioural control (n = 5/7) to be physically active. Having children in the household was negatively related to MVPA (n = 9/15). Physical activity intervention studies should consider a woman's level of self-efficacy and perceived behavioural control to be physically active. Additional studies are needed on the impact of children in the household, having a spouse/partner and using group goal setting. More evidence is needed to evaluate the impact of environmental factors. © 2016 World Obesity.

Investigators in South Carolina and Alabama assessed the availability of data for measuring 31 policy and environmental indicators for heart disease and stroke prevention. The indicators were intended to determine policy and environmental support for adopting heart disease and stroke prevention guidelines and selected risk factors in 4 settings: community, school, work site, and health care. Research teams used literature searches and key informant interviews to explore the availability of data sources for each indicator. Investigators documented the following 5 qualities for each data source identified: 1) the degree to which the data fit the indicator; 2) the frequency and regularity with which data were collected; 3) the consistency of data collected across time; 4) the costs (time, money, personnel) associated with data collection or access; and 5) the accessibility of data. Among the 31 indicators, 11 (35%) have readily available data sources and 4 (13%) have sources that could provide partial measurement. Data sources are available for most indicators in the school setting and for tobacco control policies in all settings. Data sources for measuring policy and environmental indicators for heart disease and stroke prevention are limited in availability. Effort and resources are required to develop and implement mechanisms for collecting state and local data on policy and environmental indicators in different settings. The level of work needed to expand data sources is comparable to the extensive work already completed in the school setting and for tobacco control.

In the environmental sciences, researchers are increasingly relying on automated sensors as necessary components of their work. There are many software packages available that will help users download data from internet-connected data loggers; process, store, document, and analyze the data; or provide web-based geoportals for visualization and sharing of both spatial and time-series data. However, few (if any) software packages provide a complete, end-to-end system that will meet all of the needs of any given research group. Such systems often need to be designed and built as needed. Our group specializes in creating such systems. Our portals provide rapid data discovery and contextualization, and promote collaboration. We work at multiple scales, from a small lab working at a single site in the Chihuahuan desert (SEL-Jornada), to a community portal for environmental data from Barrow, Alaska (Barrow Area Information Database Information Management System [BAID-IMS]), to a project-tracking system for US Arctic research efforts (Arctic Research Mapping Application/Arctic Observing Viewer [ARMAP/AON]). Here, we share our experiences of creating scalable systems and improving practices that address both user community and research needs.

Knowledge of the persistence of trace explosives materials is critical to aid the security community in designing detection methods and equipment. The physical and environmental factors affecting the lifetimes of particles include temperature, airflow, interparticle distance, adlayers, humidity, particle field size and vapor pressure. We are working towards a complete particle persistence model that captures the relative importance of these effects to allow the user, with known environmental conditions, to predict particle lifetimes for explosives or other chemicals. In this work, particles of explosives are sieved onto smooth glass substrates using particle sizes and loadings relevant to those deposited by fingerprint deposition. The coupon is introduced into a custom flow cell and monitored under controlled airflow, humidity and temperature. Photomicroscopy images of the sample taken at fixed time intervals are analyzed to monitor particle sublimation and characterized as a size-independent radial sublimation velocity for each particle in the ensemble. In this paper we build on previous work by comparing the relationship between sublimation of different materials and their vapor pressures. We also describe the influence of a sebum adlayer on particle sublimation, allowing us to better model `real world' samples.

This report describes the work completed on contract DE-FE0010116. The goal of this two year project was to develop and demonstrate in the laboratory a highly accurate multi-point pressure measurement fiber optic cable based on MEMS pressure sensors suitable for downhole deployment in a CO 2 sequestration well. The sensor interrogator was also to be demonstrated in a remote monitoring system and environmental testing was to be completed to indicate its downhole survivability over a lengthy period of time (e.g., 20 years). An interrogator system based on a pulsed laser excitation was shown to be capable of multiple (potentially 100+)more » simultaneous sensor measurements. Two sensors packages were completed and spliced in a cable onto the same fiber and measured. One sensor package was subsequently measured at high temperatures and pressures in supercritical CO 2, while the other package was measured prior and after being subjected to high torque stresses to mimic downhole deployment. The environmental and stress tests indicated areas in which the package design should be further improved.« less

Final environmental impact statement for the Galileo Mission (Tier 2)

NASA Technical Reports Server (NTRS)

1989-01-01

This Final Environmental Impact Statement (FEIS) addresses the proposed action of completing the preparation and operation of the Galileo spacecraft, including its planned launch on the Space Transportation System (STS) Shuttle in October 1989, and the alternative of canceling further work on the mission. The only expected environmental effects of the proposed action are associated with normal launch vehicle operation, and are treated in published National Environmental Policy Act (NEPA) documents on the Shuttle (NASA 1978) and the Kennedy Space Center (NASA 1979), and in the KSC Environmental Resources Document (NASA 1986) and the Galileo Tier 1 EIS (NASA 1988a). The environmental impacts of a normal launch were deemed insufficient to preclude Shuttle operations. Environmental impacts may also result from launch or mission accidents that could release plutonium fuel used in the Galileo power system. Intensive analysis of the possible accidents associated with the proposed action reveal small health or environmental risks. There are no environmental impacts in the no-action alternative. The remote possibility of environmental impacts of the proposed action must be weighed against the large adverse fiscal and programmatic impacts inherent in the no-action alternative.

Task rotation is used to decrease the risk of workplace injuries and improve work satisfaction. To investigate the feasibility, benefits and challenges of implementing a task rotation schedule within an underground coalmine in NSW, Australia. A mixed method case control pilot study with the development and implementation of a task rotation schedule for 6 months with two work crews. A questionnaire including The Nordic Musculoskeletal Questionnaire, The Need for Recovery after Work Scale, and The Australian WHOQOL- BREF Australian Edition was used to survey workers at baseline, 3 and 6 months. A focus group was completed with the intervention crew and management at the completion of the study. In total, twenty-seven participants completed the survey. Significant improvements in the psychological and environmental domains of the WHOQOL-BREF questionnaire were found in the intervention crew. Musculoskeletal pain was highest in the elbow, lower back and knee, and fatigue scores improved, across both groups. The intervention crew felt 'mentally fresher', 'didn't do the same task twice in a row', and 'had more task variety which made the shift go quickly'. Task rotation was positively regarded, with psychological benefits identified. Three rotations during a 9-hour shift were feasible and practical in this environment.

Pereira, R; Barbosa, S; Carvalho, F P

2014-04-01

The history of uranium mining in Portugal during almost one century has followed international demand peaks of both radium and uranium, which in turn were driven by medical, military, and civil applications. Nowadays, following price drop in the 1980s, mining activities decreased and ceased in 2001. The current challenge is to deal with environmental legacies left by old uranium mines, mainly located in Viseu and Guarda districts. In 2001, based on several radiological surveys carried out, the Portuguese government assumed the remediation costs of abandoned mine areas for environmental safety and public health protection. Detailed environmental and public health risk assessments were performed under the scope of studies both requested by the government and by funded research projects. It was found that the existing risks, due to radiological and chemical exposures to metals and radionuclide's, were particularly high at the old milling facilities and mines where in situ and heap leaching of low-grade ore occurred. The different studies, involving both humans and non-human species from different trophic levels, demonstrated the existence of effects at different levels of biological organization (molecular, cellular, tissues, individuals, and populations) and on ecosystem services. To mitigate the risks, the environmental rehabilitation works at the Urgeiriça mine complex are almost complete, while at Cunha Baixa mine, they are presently in progress. These works and environmental improvements achieved and expected are described herein.

Work capacity is related to physical, environmental and psychosocial factors and is influenced by individual characteristics and occupations. The aim of this study was to evaluated the relationship between work capacity, gender and age. 360 people employed at an institution of higher education of both genders and similar age were asked to participate in this study. The ability to work was analyzed using Work Ability Index (WAI). Descriptive statistical, Pearson correlations and ANOVA test was applied. Of these, 197 workers who participated in the study completed and returned the questionnaire. The results show there weren't any significant differences between work ability in relation to gender and age, but we observed an increase variability of responses for WAI score in older workers. No significant differences in the perception of the ability of work between men and women..

Annual Site Environmental Report: 2008 (ASER)

Sabba, D.

2009-11-09

This report provides information about environmental programs during the calendar year of 2008 at the SLAC National Accelerator Laboratory (SLAC), Menlo Park, California. Activities that span the calendar year, i.e., stormwater monitoring covering the winter season of 2008/2009 (October 2008 through May 2009), are also included. Production of an annual site environmental report (ASER) is a requirement established by the United States Department of Energy (DOE) for all management and operating (M&O) contractors throughout the DOE complex. SLAC is a federally-funded research and development center with Stanford University as the M&O contractor. Under Executive Order (EO) 13423, Strengthening Federal Environmental,more » Energy, and Transportation Management, and DOE Order 450.1A, Environmental Protection Program, SLAC effectively implements and integrates the key elements of an Environmental Management System (EMS) to achieve the site's integrated safety and environmental management system goals. For normal daily activities, SLAC managers and supervisors are responsible for ensuring that policies and procedures are understood and followed so that: (1) Worker safety and health are protected; (2) The environment is protected; and (3) Compliance is ensured. Throughout 2008, SLAC continued to improve its management systems. These systems provided a structured framework for SLAC to implement 'greening of the government' initiatives such as EO 13423 and DOE Orders 450.1A and 430.2B. Overall, management systems at SLAC are effective, supporting compliance with all relevant statutory and regulatory requirements. SLAC continues to demonstrate significant progress in implementing and integrating EMS into day-to-day operations and construction activities at SLAC. The annual management review and ranking of environmental aspects were completed this year by SLAC's EMS Steering Committee, the Environmental Safety Committee (ESC), and twelve objectives and targets were established for 2008. For each objective and target, a work plan, or Environmental Management Program (EMP) was completed and progress reports were routinely provided to SLAC senior management and the DOE SLAC Site Office (SSO). During 2008, there were no reportable releases to the environment from SLAC operations. In addition, many improvements in waste minimization, recycling, stormwater management, groundwater restoration, and SLAC's chemical management system (CMS) were continued during the year. The following are amongst SLAC's environmental accomplishments for 2008: a composting program at SLAC's onsite cafeteria was initiated, greater than 800 cubic feet of legacy radioactive waste were packaged and shipped from SLAC, a chemical redistribution program was developed, SLAC reduced the number of General Services Administration leased vehicles from 221 to 164, recycling of municipal waste was increased by approximately 140 tons during 2008, and site-wide releases of sulfur hexafluoride were reduced by 50 percent. In 2008, no radiological incidents occurred that increased radiation levels or released radioactivity to the environment. In addition to managing its radioactive wastes safely and responsibly, SLAC worked to reduce the amount of waste generated. SLAC has implemented programs and systems to ensure compliance with all radiological requirements related to the environment. Specifically, the Radiation Protection Radiological Waste Management Group developed a training course to certify Radioactive Waste Generators, conducted a training pilot, and developed a list of potential radioactive waste generators to train. Twenty eight generators were trained in 2008. As a best management practice, SLAC also reduced its tritium inventory by at least 95 percent by draining one of its accelerator cooling water systems; with the cooperation of the South Bayside System Authority, the West Bay Sanitary District and the DOE, SLAC discharged the cooling water to the sanitary sewer according to federal regulations and replenished the system with clean water. In 2008, the SLAC Environmental Restoration Program personnel continued work on site characterization and evaluation of remedial alternatives at four sites with volatile organic compounds in groundwater and several areas with polychlorinated biphenyls and low concentrations of lead in soil. SLAC is regulated under a site cleanup requirements order (board order) issued by the California Regional Water Quality Control Board (RWQCB), San Francisco Bay Region in May 2005 for the investigation and remediation of impacted soil and groundwater at SLAC. The board order lists specific tasks and deadlines for completion of groundwater and soil characterization and other remediation activities. All 2008 submittals to the RWQCB were completed and submitted on time.« less

The River Corridor Closure Contract How Washington Closure Hanford is Closing A Unique Department of Energy Project - 12425

Feist, E.T.

2012-07-01

Cleanup of the Hanford River Corridor has been one of Hanford Site's top priorities since the early 1990's. This urgency is due to the proximity of hundreds of waste sites to the Columbia River and the groundwater that continues to threaten the Columbia River. In April 2005, the U.S. Department of Energy, Richland Operations Office (DOE-RL) awarded the Hanford River Corridor Closure Contract (RCCC), a cost-plus incentive-fee closure contract with a 2015 end date and first of its kind at Hanford Site, to Washington Closure Hanford (WCH), a limited-liability company owned by URS, Bechtel National, and CH2M HILL. WCH ismore » a single-purpose company whose goal is to safely, compliantly, and efficiently accelerate cleanup in the Hanford River Corridor and reduce or eliminate future obligations to DOE-RL for maintaining long-term stewardship over the site. Accelerated performance of the work-scope while keeping a perspective on contract completion presents challenges that require proactive strategies to support the remaining work-scope through the end of the RCCC. This paper outlines the processes to address the challenges of completing work-scope while planning for contract termination. WCH is responsible for cleanup of the River Corridor 569.8 km{sup 2} (220 mi{sup 2}) of the 1,517.7 km{sup 2} (586 mi{sup 2}) Hanford Site's footprint reduction. At the end of calendar year 2011, WCH's closure implementation is well underway. Fieldwork is complete in three of the largest areas within the RCCC scope (Segments 1, 2, and 3), approximately 44.5% of the River Corridor (Figure 3). Working together, DOE-RL and WCH are in the process of completing the 'paper work' that will document the completion of the work-scope and allow DOE-RL to relieve WCH of contractual responsibilities and transition the completed areas to the Long-Term Stewardship Program, pending final action RODs. Within the next 4 years, WCH will continue to complete cleanup of the River Corridor following the completion goals. As field work-scope is completed, progressive reductions of business processes, physical facilities, and staff will occur. Organizations will collapse and flatten commensurate with workload. WCH employees will move on to new endeavors, proud of their accomplishments and the legacy they are leaving behind as being the first and largest environmental cleanup closure contract at Hanford.

Tillman, Jack B.

In March 2008, Sandia National Laboratories (Sandia), in partnership with the Bureau of Land Management, Roswell Field Office, completed its responsibilities to plug and abandon wells and restore the surface conditions for the Sulimar Queens Unit, a 2,500 acre oil field, in Chaves County, Southeast New Mexico. Sandia assumed this liability in an agreement to obtain property to create a field laboratory to perform extensive testing and experimentation on enhanced oil recovery techniques for shallow oil fields. In addition to plugging and abandoning 28 wells, the project included the removal of surface structures and surface reclamation of disturbed lands associatedmore » with all plugged and abandoned wells, access roads, and other auxiliary facilities within unit boundaries. A contracting strategy was implemented to mitigate risk and reduce cost. As the unit is an important wildlife habitat for prairie chickens, sand dune lizards, and mule deer, the criteria for the restoration and construction process were designed to protect and enhance the wildlife habitat. Lessons learned from this project include: (1) extreme caution should be exercised when entering agreements that include future liabilities, (2) partnering with the regulator has huge benefits, and (3) working with industry experts, who were familiar with the work, and subcontractors, who provided the network to complete the project cost effectively.« less

Improvement of General Electric’s Chilled Ammonia Process with the use of Membrane Technology

DOE Office of Scientific and Technical Information (OSTI.GOV)

Muraskin, Dave; Dube, Sanjay; Baburao, Barath

General Electric Environmental Control Solutions (formerly Alstom Power Environmental Control Systems) set out to complete the Phase 1 award requirements for a Phase II renewal application for their project selected under DOE-FOA-0001190 “Small and Large Scale Pilots for Reducing the Cost of CO 2 Capture and Compression”. The project focus was to implement several improvement concepts utilizing membrane technology at the recipient’s Chilled Ammonia Process (CAP) CO 2 capture large-scale pilot plant. The goal was to lower the overall cost of technology. During the development of costs for the preliminary techno-economic assessment (TEA), it became clear that the capital andmore » operating costs of this concept were not economically attractive. All work related to a Phase II renewal application at that point was halted as GE made the decision not to submit a Phase II renewal application. Discussions with DOE resulted in a path towards useful information produced from the design and cost work already completed on the project. With the reverse osmosis (RO) unit providing most of the cost issues, GE would provide a sensitivity analysis of the RO unit with respect to project cost. This information would be included with the Techno-Economic Analysis along with the Technology Gap Analysis.« less

This study aimed to examine potential differences in walking, cycling, public transport and passive transport (car/moped/motorcycle) to work and to other destinations between college and non-college educated working young adults. Secondly, we aimed to investigate which psychosocial and environmental factors are associated with the four transport modes and whether these associations differ between college and non-college educated working young adults. In this cross-sectional study, 224 working young adults completed an online questionnaire assessing socio-demographic variables (8 items), psychosocial variables (6 items), environmental variables (10 items) and transport mode (4 types) and duration to work/other destinations. Zero-inflated negative binomial regression models were performed in R. A trend (p<0.10) indicated that more college educated compared to non-college educated young adults participated in cycling and public transport. However, another trend indicated that cycle time and public transport trips were longer and passive transport trips were shorter in non-college compared to college educated working young adults. In all working young adults, high self-efficacy towards active transport, and high perceived benefits and low perceived barriers towards active and public transport were related to more active and public transport. High social support/norm/modeling towards active, public and passive transport was related to more active, public and passive transport. High neighborhood walkability was related to more walking and less passive transport. Only in non-college educated working young adults, feeling safe from traffic and crime in their neighborhood was related to more active and public transport and less passive transport. Educational levels should be taken into account when promoting healthy transport behaviors in working young adults. Among non-college educated working young adults, focus should be on increasing active and public transport participation and on increasing neighborhood safety to increase active and public transport use. Among college educated working young adults, more minutes of active transport should be encouraged.

Cao, Yue; Walker, Elizabeth A.; Krause, James S.

2015-01-01

Objective Although previous studies have found environmental barriers to be associated with social participation and life satisfaction after spinal cord injury (SCI), few studies exist reporting their effects on subjective health after SCI. Our purpose was to identify the prevalence of perceived environmental barriers and their effects on subjective health in persons with chronic SCI who completed two repeated measurements during a 5-year longitudinal study. Design This is a prospective cohort study. Environmental barriers were measured at baseline by the Craig Hospital Inventory of Environmental Factors-Short Form. Subjective health was measured at baseline and 5-year follow-up by days of physical and mental health not good. Other control variables included sex, race, age at injury, years since injury, and injury severity at baseline. Setting Data were collected at a specialty hospital and analyzed at a medical university in the Southeastern USA. Participants A total of 1635 participants completed both baseline and follow-up surveys. Results Twenty per cent of participants reported at least one policy barrier, 46% at least one physical and structural barrier, 22% at least one attitudinal and support barrier, 26% at least one barrier to services and assistance, and 13% at least one barrier at work or school. After controlling for sex, race, age at injury, years since injury, and injury severity, the physical and structural barriers, and services and assistance barriers measured at baseline significantly predicted subjective physical and mental health measured at follow-up. Conclusion Environmental barriers are prevalent among people with chronic SCI. They are important predictors for future subjective health. PMID:25329423

While the work situation for nurse assistants in residential care is strenuous, they themselves often state that they are satisfied with their job. More knowledge is clearly needed of the interrelationship of variables associated with job satisfaction. This study aims to investigate job satisfaction and explore associated variables among nurse assistants working in residential care. A total of 225 respondents completed a questionnaire measuring general job satisfaction, satisfaction with nursing-care provision and measures concerning person-centered care, work climate, leadership, and health complaints. Job satisfaction was the outcome measure and comparisons were made among those reporting low, moderate, and high levels of job satisfaction; multiple regression analyses were used to explore associated variables. The caring climate and personalized care provision were associated with general job satisfaction. High levels of satisfaction with nursing-care provision were also associated with the general work climate, organizational and environmental support, and leadership. Low job satisfaction was mainly associated with health complaints. Nurse assistants working in a positive work climate, caring climate, with a positive attitude to their leaders, who receive organizational and environmental support, provide person-centered care and experience a higher degree of job satisfaction. It seems essential, however, to include both general and context-specific measures when investigating job satisfaction in this field as they reveal different aspects of the nurse assistant's work situation.

DEACTIVATION AND DECOMMISSIONING ENVIRONMENTAL STRATEGY FOR THE PLUTONIUM FINISHING PLANT COMPLEX, HANFORD NUCLEAR RESERVATION

Hopkins, A.M.; Heineman, R.; Norton, S.

Maintaining compliance with environmental regulatory requirements is a significant priority in successful completion of the Plutonium Finishing Plant (PFP) Nuclear Material Stabilization (NMS) Project. To ensure regulatory compliance throughout the deactivation and decommissioning of the PFP complex, an environmental regulatory strategy was developed. The overall goal of this strategy is to comply with all applicable environmental laws and regulations and/or compliance agreements during PFP stabilization, deactivation, and eventual dismantlement. Significant environmental drivers for the PFP Nuclear Material Stabilization Project include the Tri-Party Agreement; the Resource Conservation and Recovery Act of 1976 (RCRA); the Comprehensive Environmental Response, Compensation and Liability Actmore » of 1980 (CERCLA); the National Environmental Policy Act of 1969 (NEPA); the National Historic Preservation Act (NHPA); the Clean Air Act (CAA), and the Clean Water Act (CWA). Recent TPA negotiation s with Ecology and EPA have resulted in milestones that support the use of CERCLA as the primary statutory framework for decommissioning PFP. Milestones have been negotiated to support the preparation of Engineering Evaluations/Cost Analyses for decommissioning major PFP buildings. Specifically, CERCLA EE/CA(s) are anticipated for the following scopes of work: Settling Tank 241-Z-361, the 232-Z Incinerator, , the process facilities (eg, 234-5Z, 242, 236) and the process facility support buildings. These CERCLA EE/CA(s) are for the purpose of analyzing the appropriateness of the slab-on-grade endpoint Additionally, agreement was reached on performing an evaluation of actions necessary to address below-grade structures or other structures remaining after completion of the decommissioning of PFP. Remaining CERCLA actions will be integrated with other Central Plateau activities at the Hanford site.« less

The objectives were (1) to define physical activity (PA) and sedentary behaviors (SB) patterns in daily life contexts (work, leisure, and transportation) in French working women from NutriNet-Santé web-cohort and (2) to identify pattern(s) of active transportation and their individual, social, and environmental correlates. 23,432 participants completed two questionnaires to evaluate PA and SB in daily life contexts and individual representations of residential neighborhood and transportation modes. Hierarchical cluster analysis was performed which identified 6 distinct movement behavior patterns: (i) active occupation, high sedentary leisure, (ii) sedentary occupation, low leisure, (iii) sedentary transportation, (iv) sedentary occupation and leisure, (v) active transportation, and (vi) active leisure. Multinomial logistic regressions were performed to identify correlates of the "active transportation" cluster. The perceived environmental characteristics positively associated with "active transportation" included "high availability of destinations around home," "presence of bicycle paths," and "low traffic." A "positive image of walking/cycling," the "individual feeling of being physically active," and a "high use of active transport modes by relatives/friends" were positively related to "active transportation," identified as a unique pattern regarding individual and environmental correlates. Identification of PA and SB context-specific patterns will help to understand movement behaviors' complexity and to design interventions to promote active transportation in specific subgroups.

Environmental Control Units (ECU) are devices or a system that allows a person to control appliances in their home or work environment. Such system can be utilized by clients with physical and/or functional disability to enhance their ability to control their environment, to promote independence and improve their quality of life. Over the last several years, there have been an emergence of several inexpensive, commercially-available, voice activated smart speakers into the market such as Google Home and Amazon Echo. These smart speakers are equipped with far field microphone that supports voice recognition, and allows for complete hand-free operation for various purposes, including for playing music, for information retrieval, and most importantly, for environmental control. Clients with disability could utilize these features to turn the unit into a simple ECU that is completely voice activated and wirelessly connected to appliances. Smart speakers, with their ease of setup, low cost and versatility, may be a more affordable and accessible alternative to the traditional ECU. Implications for Rehabilitation Environmental Control Units (ECU) enable independence for physically and functionally disabled clients, and reduce burden and frequency of demands on carers. Traditional ECU can be costly and may require clients to learn specialized skills to use. Smart speakers have the potential to be used as a new-age ECU by overcoming these barriers, and can be used by a wider range of clients.

Higher screen-viewing levels increase the risk of obesity. Understanding the correlates of screen viewing is an important first step in designing interventions but there is lack of information on the correlates among Spanish children. This study examined associations among environmental, sociocultural, age variables and screen viewing among Spanish children. Children completed a questionnaire about time spent in screen viewing. BMI was assessed and children were classified into obesity groups using International Obesity Task Force cut-off points. Parents completed a questionnaire about sociodemographic, environmental and sociocultural variables. Participants were 247 primary and 256 secondary school-aged children and their parents. Time spent in screen viewing increased with age. Males spent more time than females in screen viewing. Greater access to bedroom media sources was associated with higher screen viewing. Younger children from single-parent households and older children having a younger parent, siblings and a father who was not working were higher screen-viewers on weekends and weekdays, respectively. For older children parental TV viewing time appeared to be a significant correlate, while parental rules was a determinant predictor for younger children on weekdays. Environmental and sociocultural factors influence the time children spend in screen viewing. Parents play a central role in child's screen viewing; therefore, interventions that target environmental and family TV viewing practices are likely to be effective.

In the coastal areas north-east and south-west of Knysna, South Africa lie natural forests, lakes and lagoons highly regarded by many for their aesthetic and ecological richness. A freeway construction project has given rise to fears of the degradation or destruction of these natural features. The possibility was investigated of using ERTS imagery to estimate the environmental impact of the freeway and found that: (1) All threatened features could readily be identified on the imagery. (2) It was possible within a short time to provide an area estimate of damage to indigenous forest. (3) In several important respects the imagery has advantages over maps and aerial photos for this type of work. (4) The imagery will enable monitoring of the actual environmental impact of the freeway when completed.

Active commuting (AC), the act of walking or biking to work, has notable health benefits though rates of AC remain low among women. This study used a social-ecological framework to examine the factors associated with AC among women. A convenience sample of employed, working women (n = 709) completed an online survey about their mode of travel to work. Individual, interpersonal, institutional, community, and environmental influences were assessed. Basic descriptive statistics and frequencies described the sample. Simple logistic regression models examined associations with the independent variables with AC participation and multiple logistic regression analysis determined the relative influence of social ecological factors on AC participation. The sample was primarily middle-aged (44.09±11.38 years) and non-Hispanic White (92%). Univariate analyses revealed several individual, interpersonal, institutional, community and environmental factors significantly associated with AC. The multivariable logistic regression analysis results indicated that significant factors associated with AC included number of children, income, perceived behavioral control, coworker AC, coworker AC normative beliefs, employer and community supports for AC, and traffic. The results of this study contribute to the limited body of knowledge on AC participation for women and may help to inform gender-tailored interventions to enhance AC behavior and improve health.

Building Health Sciences, Inc. (BHS), investigated environmental conditions by many modalities in 71 discreet areas of 12 buildings in a government building complex that had experienced persistent occupant complaints despite correction of deficiencies following a prior survey. An online health survey was completed by 7,637 building occupants (49% response rate), a subset of whom voluntarily wore personal sampling apparatus and underwent medical evaluation. Building environmental measures were within current standards and guidelines, with few outliers. Four environmental factors were consistently associated with group-level building-related health complaints: physical comfort/discomfort, odor, job stress, and glare. Several other factors were frequently commented on by participants, including cleanliness, renovation and construction activities, and noise. Low relative humidity was significantly associated with lower respiratory and "sick building syndrome"-type symptoms. No other environmental conditions (including formaldehyde, PM10 [particulate matter with an aerodynamic diameter <10 μm], or mold levels, which were tested by 7 parameters) correlated directly with individual health symptoms. Indicators of atopy or allergy (sinusitis, allergies, and asthma), when present singly, in combinations of 2 conditions, or together, were hierarchically associated with the following: increased absence, increased presenteeism (presence at work but at reduced capacity), and increase in reported symptom-days, including symptoms not related to respiratory disease. We found that in buildings without unusual hazards and with environmental and air quality indicators within the range of acceptable indoor air quality standards, there is an identifiable population of occupants with a high prevalence of asthma and allergic disease who disproportionately report discomfort and lost productivity due to symptoms and that in "normal" buildings these outcome indicators are more closely associated with host factors than with environmental conditions. We concluded from the experience of this study that building-related health complaints should be investigated at the work-area level and not at a building-wide level. An occupant-centric medical evaluation should guide environmental investigations, especially when screening results of building indoor environmental and air quality measurements show that the building and its work areas are within regulatory standards and industry guidelines.

Health and related claims on food labels can support consumer education initiatives that encourage purchase of healthier foods. A new food Standard on Nutrition, Health and Related Claims became law in January 2013. Implementation will need careful monitoring and enforcement to ensure that claims are truthful and have meaning. The current study explored factors that may impact on environmental health officers' food labelling policy enforcement practices. The study used a mixed-methods approach, using two previously validated quantitative questionnaire instruments that provided measures of the level of control that the officers exercised over their work, as well as qualitative, semi-structured, in-depth interviews. Local government; Australia. Thirty-seven officers in three Australian states participated in semi-structured in-depth interviews, as well as completing the quantitative questionnaires. Senior and junior officers, including field officers, participated in the study. The officers reported a high level of autonomy and control of their work, but also a heavy workload, dominated by concerns for public health and food safety, with limited time for monitoring food labels. Compliance of labels with proposed health claims regulations was not considered a priority. Lipsky's theory of street-level bureaucracy was used to enhance understanding of officers' work practices. Competing priorities affect environmental health officers' monitoring and enforcement of regulations. Understanding officers' work practices and their perceptions of enforcement is important to increase effectiveness of policy implementation and hence its capacity to augment education initiatives to optimize health benefits.

Wallace, Peter; Holzer, Joseph; Guarro, Sergio; Hyatt, Larry

1987-01-01

The Embedded System Safety Analysis Assistant (ESSAA) is a knowledge-based tool that can assist in identifying disaster scenarios. Imbedded software issues hazardous control commands to the surrounding hardware. ESSAA is intended to work from outputs to inputs, as a complement to simulation and verification methods. Rather than treating the software in isolation, it examines the context in which the software is to be deployed. Given a specified disasterous outcome, ESSAA works from a qualitative, abstract model of the complete system to infer sets of environmental conditions and/or failures that could cause a disasterous outcome. The scenarios can then be examined in depth for plausibility using existing techniques.

The safety policy of LLNL is to take every reasonable precaution in the performance of work to protect the environment and the health and safety of employees and the public, and to prevent property damage. With respect to hazardous agents, this protection is provided by limiting human exposures, releases to the environment, and contamination of property to levels that are as low as reasonably achievable (ALARA). It is the intent of this Plan to supply the broad outline for completing environmental investigations within ALARA guidelines. It may not be possible to determine actual working conditions in advance of the work;more » therefore, planning must allow the opportunity to provide a range of protection based upon actual working conditions. Requirements will be the least restrictive possible for a given set of circumstances, such that work can be completed in an efficient and timely fashion. Due to the relatively large size of the LLNL Site and the different types of activities underway, site-specific Operational Safety Procedures (OSPs) will be prepared to supplement activities not covered by this Plan. These site-specific OSPs provide the detailed information for each specific activity and act as an addendum to this Plan, which provides the general plan for LLNL Main Site operation.« less

Introducing future engineers to sustainable ecology problems: a case study

NASA Astrophysics Data System (ADS)

Filipkowski, A.

2011-12-01

The problem of Earth environmental destruction by human activities is becoming dangerous. Engineers responsible for the production of any goods should be well aware of the negative influence of their activities on the state of the planet. This is why the understanding of ecological problems is essential for people responsible for production and industrial design. The energy, which they consume, is increasing the greenhouse effect and the waste poisons the environment. So far, most courses on ecology are offered to specialists in environmental engineering. These courses are filled with many details. The Warsaw Academy of Computer Science, Management and Administration teaches students in the direction of management and production engineering. Upon completion, the students receive the degree of 'engineer'. Their future work will mainly concern management of different types of industrial enterprises and they will be responsible for organising it in such a way as to avoid a dangerous contribution to environmental pollution and climate change. This is why it was decided to introduce a new course entitled 'Principles of Ecology and Environmental Management'. This course is quite broad, concerning almost all technical, law and organisational aspects of the problem. The presentation is made in a spectacular way, aiming to convince students that their future activity must be environmentally friendly. It contains information about international activities in ecology, legal aspects concerning pollution, technical and information methods of monitoring and, finally, the description of 'green' solutions. Altogether, 27 hours of lectures and 15 hours of discussions and students' presentations complete the course. Details of this course are described in this paper.

The aim of this study was to determine which combination of personal, disease-related and environmental factors is best associated with at-work productivity loss in patients with rheumatoid arthritis (RA), and to determine whether at-work productivity loss is associated with the quality of life for these patients. This study is based on cross-sectional data. Patients completed a questionnaire with personal, disease-related and environmental factors (related to the work environment), and clinical characteristics were obtained from patient medical records. At-work productivity loss was measured with the Work Limitations Questionnaire, and quality of life with the RAND 36. Using linear regression analyses, a multivariate model was built containing the combination of factors best associated with at-work productivity loss. This model was cross-validated internally. We furthermore determined whether at-work productivity loss was associated with quality of life using linear regression analyses. We found that at-work productivity loss was associated with workers who had poorer mental health, more physical role limitations, were ever treated with a biological therapeutic medication, were not satisfied with their work, and had more work instability (R(2) = 0.50 and R(2) following cross-validation was 0.32). We found that at-work productivity loss was negatively associated with health-related quality of life, especially with dimensions of mental health, physical role limitations, and pain. We found that at-work productivity loss was associated with personal, work-related, and clinical factors. Although our study results should be interpreted with caution, they provide insight into patients with RA who are at risk for at-work productivity loss.

People with mental illnesses face stigma that hinders their full integration into society. Work is a major determinant of social inclusion, however, people with mental disorders have fewer opportunities to work. Emerging evidence suggests that social enterprises help disadvantaged people with their work integration process. The purpose of this study is to enhance our understanding about how perceptions of stigma can be decreased for people with mental disorders throughout their work experience in a social enterprise. Using a longitudinal study design, 310 individuals with mental disorders employed in Italian social enterprises completed a battery of questionnaires on individual (e.g., severity of symptoms; occupational self-efficacy) and environmental (e.g., social support; organizational constraints) variables. Of the 223 individuals potentially eligible at the 12-month follow up, 139 completed a battery of questionnaires on social and working skills, perceived work productivity and perceived stigma. Path analyses were used to test a model delineating how people with mental disorders working in social enterprises improve social and work outcomes (i.e., motivation, skills and productivity), and reduce the perception of being stigmatized. Working in a social enterprise enhances working social skills, which leads to a perception of higher productivity and, consequently, the perception of being discriminated against and stigmatized is reduced. Social enterprise provides a context in which people with mental disorders reach a sense of work-related and social competence. This sense of competence helps them to reduce perceived stigma, which is a crucial step toward social inclusion. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

Surface preparation activities conducted during automotive refinishing present several potential human health and environmental risks. This study examines the chemical composition of vehicle sanding dust and the prevalence of methylene chloride use as a basis for evaluating potential chemical exposures in the work environment, fugitive environmental releases, and take-home toxics. This article reports on the findings of (1) a statewide technology and work practices survey of 353 licensed auto body shops and (2) laboratory analyses of sanding dust representing more than 200 vehicles, 10 commercial body filler compounds, and work shirts worn during vehicle sanding while using nonventilated equipment. Survey data revealed that the majority of shops (78%) do not use ventilated sanding equipment, that most workers (55%) take their work clothes and shoes home at the end of the workday, and that 17% of the respondents used a methylene chloride-based paint stripper as an adjunct to mechanical sanding. Laboratory results showed that Pb, As, Cr, Mn, and Ni were present in the sanding dust at every facility tested. Lead concentrations in sanding dust were found to be highest at facilities that performed complete vehicle refinishing (range 770 to 7300 ppm) and at a collision repair shop that used a high-lead content body filler compound (1800 ppm). Hexavalent chromium also was found in two vocational high school paint dust samples at concentrations of 54 and 710 ppm. When total lead and chromium concentrations reached 7300 and 2300 ppm, respectively, facility sanding dust samples failed the U.S. Environmental Protection Agency's Toxicity Characteristic Leaching Procedure for hazardous waste. Metals found in the sanding dust also were present on the work shirts of technicians-ranging from 0.06 (Cd) to 81 (Mg) microg/inch2 of cloth-who sanded on paint without ventilated equipment. Results suggest that sanding dust and methylene chloride paint strippers used in vehicle resurfacing operations pose a potential hazard to human health and the environment.

2002-01-01

The primary purpose of this project was to evaluate and improve models for the bulk-skin temperature difference to the point where they could accurately and reliably apply under a wide variety of environmental conditions. To accomplish this goal, work was conducted in three primary areas. These included production of an archive of available data sets containing measurements of the skin and bulk temperatures and associated environmental conditions, evaluation of existing skin layer models using the compiled data archive, and additional theoretical work on the development of an improved model using the data collected under diverse environmental conditions. In this work we set the basis for a new physical model of renewal type, and propose a parameterization for the temperature difference across the cool skin of the ocean in which the effects of thermal buoyancy, wind stress, and microscale breaking are all integrated by means of the appropriate renewal time scales. Ideally, we seek to obtain a model that will accurately apply under a wide variety of environmental conditions. A summary of the work in each of these areas is included in this report. A large amount of work was accomplished under the support of this grant. The grant supported the graduate studies of Sandra Castro and the preparation of her thesis which will be completed later this year. This work led to poster presentations at the 1999 American Geophysical Union Fall Meeting and 2000 IGARSS meeting. Additional work will be presented in a talk at this year's American Meteorological Society Air-Sea Interaction Meeting this May. The grant also supported Sandra Castro during a two week experiment aboard the R/P Flip (led by Dr. Andrew Jessup of the Applied Physics Laboratory) to help obtain additional shared data sets and to provide Sandra with a fundamental understanding of the physical processes needed in the models. In a related area, the funding also partially supported Dr. William Emery and Daniel Baldwin in the preparation of their publication "Accuracy of in situ sea surface temperatures used to calibrate infrared satellite measurements".

Sediment problems in urban areas

USGS Publications Warehouse

Guy, Harold P.

1970-01-01

One obstacle to a scientific recognition and an engineering solution to sediment-related environmental problems is that such problems are bound in conflicting and generally undefinable political and institutional restraints. Also, some of the difficulty may involve the fact that the scientist or engineer, because of his relatively narrow field of investigation, cannot always completely envision the less desirable effects of his work and communicate alternative solutions to the public. For example, the highway and motor-vehicle engineers have learned how to provide the means by which one can transport himself from one point to another with such great efficiency that a person's employment in this country is now commonly more than 5 miles from his residence. However, providing such efficient personal transport has created numerous serious environmental problems. Obstacles to recognition of and action to control sediment problems in and around urban areas are akin to other environmental problems with respect to the many scientific, engineering, economic, and social aspects.

Recent work on procrastination has begun to unravel the genetic and environmental correlates of this problematic behavior. However, little is known about how strongly procrastination is associated with internalizing and externalizing psychopathology, and the extent to which shared genetic/environmental factors or relevant personality constructs (e.g., fear of failure, impulsivity, and neuroticism) can inform the structure of these associations. The current study examined data from 764 young adult twins who completed questionnaires assessing procrastination and personality and structured interviews regarding psychopathology symptoms. Results indicated that procrastination was positively correlated with both internalizing and externalizing latent variables, and that these correlations were driven by shared genetic influences. Moreover, the association between procrastination and internalizing was accounted for by fear of failure and neuroticism, whereas the association between procrastination and externalizing was primarily explained by impulsivity. The role of procrastination in psychopathology is discussed using a framework that highlights common and broadband-specific variance.

Existing STEM retention and diversity programs have identified access to field and professional experiences as critical to helping students identify as scientists, form networks, and gain important skills necessary for employment. This program reimagines the traditional geology field course as a professional development experience for students at 2-year and 4-year institutions interested in environmental careers. Students participate in a summer field course in the Sierra Nevada of California, during which time they complete geology, geomorphology, hydrology, and ecology field projects designed to compliment the curriculum of Environmental Geoscience, Environmental Science, and Environmental Studies programs. During the course students interact with local professionals in the environmental sector and work to earn badges based on the skills demonstrated during field projects. Badges create transparent documentation of skill mastery for students and provide a new way for students to understand and market their skills and competencies to potential employers. We will report on the curriculum development, implementation and assessment of the first cohort of students to participate in the program. Preliminary results of formative and summative assessments and their implications for student success and program design will be addressed.

The purpose of this study was to investigate manual performance and thermal responses during low work intensity in persons wearing standard protective clothing in the petroleum industry when they were exposed to a range of temperatures (5, -5, -15 and -25℃) that are relevant to environmental conditions for petroleum industry personnel in northern regions. Twelve men participated in the study. Protective clothing was adjusted for the given cold exposure according to current practices. The subjects performed manual tests five times under each environmental condition. The manual performance test battery consisted of four different tests: tactile sensation (Semmes-Weinstein monofilaments), finger dexterity (Purdue Pegboard), hand dexterity (Complete Minnesota dexterity test) and grip strength (grip dynamometer). We found that exposure to -5℃ or colder lowered skin and body temperatures and reduced manual performance during low work intensity. In conclusion the current protective clothing at a given cold exposure is not adequate to maintain manual performance and thermal balance for petroleum workers in the high north.

EPA Pesticide Factsheets

These assessments will focus on the use of DCM and NMP in paint stripping. NMP exposures scenarios for this use result in inhalation and dermal exposure to consumers and workers. The low concern for environmental effects of NMP will be discussed in the assessment. In the case of DCM, there are human health concerns for both cancer and non-cancer effects. This DCM assessment of paint stripping uses will focus only on inhalation exposure to consumers and workers. The low concern for environmental effects of DCM will be discussed in the assessment. EPA anticipates issuing draft risk assessments for public review and comment as they are completed. At the conclusion of the review process, if an assessment of specific uses indicates significant risk, EPA will evaluate and pursue appropriate risk reduction actions, as warranted. If an assessment indicates no significant risk, EPA will conclude its current work on assessment of those specified targeted uses of that chemical. Over time, additional chemicals will be added to the work plan as more data are developed and more chemicals screened.

Diagnosing an environmental or occupationally related pulmonary disorder often involves a process of elimination. Unlike commonly diagnosed conditions in other specialties, a cause-and-effect relationship may be implied, yet other factors such as temporality and biologic plausibility are lacking. Our patient was referred with a suspected work-related pulmonary disorder. For several years, she had suffered with dyspnea on exertion and repeated flulike illnesses. She worked at an automobile repair garage that performed a large number of emission tests, and there was concern that her workplace exposures were the cause of her symptoms. After a careful review of her history, physical examination, and laboratory testing, we came to the conclusion that she had hypersensitivity pneumonitis related to pet cockatiels in her home. Clinical points of emphasis include the importance of a complete environmental history and careful auscultation of the chest when performing the physical examination. In addition, we encountered an interesting physical diagnostic clue, a respiratory sound that assisted with the eventual diagnosis.

2009-03-01

The flexural strength of 1 wt.% Ag-doped Bi2Sr2CaCu2O8+δ thin rods textured by a laser heated floating zone was measured as a function of the environmental conditions (air versus water) at room temperature. Loading rates spanning three orders of magnitude (1, 10 and 100 μm/min) were used to explore their susceptibility to the environmental conditions. These mechanical tests were completed with electrical characterization (critical current at 77K and resistivity from 77 to 300 K) of samples submerged in distilled water for different time lengths (0, 12 and 120h). While Bi2Sr2CaCu2O8+δ has been shown, in previous works, to be unstable during contact with water molecules, the Ag-doped Bi-2212 textured rods tested in this work are very inert to the water environment, with respect to their mechanical and electrical properties, due to the presence of a narrow (approx150 μm) low textured outer ring formed in the growth process.

The objectives were (1) to define physical activity (PA) and sedentary behaviors (SB) patterns in daily life contexts (work, leisure, and transportation) in French working women from NutriNet-Santé web-cohort and (2) to identify pattern(s) of active transportation and their individual, social, and environmental correlates. 23,432 participants completed two questionnaires to evaluate PA and SB in daily life contexts and individual representations of residential neighborhood and transportation modes. Hierarchical cluster analysis was performed which identified 6 distinct movement behavior patterns: (i) active occupation, high sedentary leisure, (ii) sedentary occupation, low leisure, (iii) sedentary transportation, (iv) sedentary occupation and leisure, (v) active transportation, and (vi) active leisure. Multinomial logistic regressions were performed to identify correlates of the “active transportation” cluster. The perceived environmental characteristics positively associated with “active transportation” included “high availability of destinations around home,” “presence of bicycle paths,” and “low traffic.” A “positive image of walking/cycling,” the “individual feeling of being physically active,” and a “high use of active transport modes by relatives/friends” were positively related to “active transportation,” identified as a unique pattern regarding individual and environmental correlates. Identification of PA and SB context-specific patterns will help to understand movement behaviors' complexity and to design interventions to promote active transportation in specific subgroups.

Functional analysis of the stress response element and its role in the multistress response of Saccharomyces cerevisiae.

PubMed

Treger, J M; Magee, T R; McEntee, K

1998-02-04

The DDR2 gene of Saccharomyces cerevisiae is a multistress response gene whose transcription is rapidly and strongly induced by a diverse array of xenobiotic agents, and environmental and physiological conditions. The multistress response of this gene requires the pentanucleotide, 5' CCCCT, (C4T;STRE (STress Response Element)) and the zinc-finger transcription factors, Msn2p and Msn4p. A 51bp oligonucleotide (oligo 31/32) containing two STREs from the DDR2 promoter region was previously shown to direct heat shock activation of a lacZ reporter gene. In this work we demonstrate that the same element conferred a complete multistress response to an E. coli galK reporter gene introduced into yeast cells. A variant oligonucleotide in which both the STRE spacing and neighboring sequences were altered responded to the same spectrum of stresses, while substitution of nucleotides within the pentanucleotide completely abolished the multistress response. These results directly demonstrate that STREs are not only necessary but are sufficient for mediating a transcriptional response to a surprisingly diverse set of environmental and physiological conditions.

The purpose of this study was to assess audiologists' perceptions of ethics and moral climate in the workplace. The Ethics Environmental Questionnaire (EEQ) was sent out to all audiologists registered with the professional body Audiology Australia. Participants were also invited to undertake a semi-structured interview. A total of 301 audiologists completed the questionnaire. Eight of these participants also agreed to complete the interview. The overall mean on the EEQ was approximately equivalent to that of a positive ethical environment, with the exception of those working in adult rehabilitation settings who scored significantly poorer. Scores were significantly associated with state and age. Qualitative analysis from the interviews found that sales pressure from employers was the dominant cause for concern amongst the group. For those working in adult rehabilitation, moral distress is most likely to occur as the result of conflicting goals between the organisation and the audiologist. There is a need to regulate the practice at an organisational as well as individual level to ensure the focus remains on ethical practice.

A rapid increase in the incidence of Crohn's disease and ulcerative colitis in developed countries, the occurrence of Crohn's disease in spouses, and a lack of complete concordance in monozygotic twins are strong arguments for the role of environmental factors in inflammatory bowel disease (IBD). Research in the field of environmental factors in IBD is based upon epidemiological (geographical and case-control), clinical and experimental studies. The role of two environmental factors has clearly been established in IBD. Smoking is a risk factor for Crohn's disease and a protective factor for ulcerative colitis; appendectomy is a protective factor for ulcerative colitis. Many other environmental factors for IBD have been investigated, including infectious agents, diet, drugs, stress and social status. They are detailed in the present review. Among them, atypical Mycobacteria, oral contraceptives and antibiotics could play a role in Crohn's disease. To date, three hypotheses associate environmental factors with the pathophysiology of IBD (loss of tolerance of intestinal immune system towards commensal bacterial flora): the hygiene, infection and cold chain hypotheses. Much work remains to be done to identify risk factors for IBD. Research identifying environmental factors that might cause a predisposition to IBD is useful. It may lead to disease prevention in subjects who are genetically predisposed and disease improvement in patients.

The Aviation Environmental Technical Branch produces many various types of aeronautical research that benefits the NASA mission for space exploration and in turn, produces new technology for our nation. One of the present goals of the Aviation Environmental Technical Branch is to create better engines for airplanes by testing supersonic jet propulsion and safe fuel combustion. During the summer of 2004, I was hired by Vincent Sattenvhite Chief executive of the Aviation Environmental Technical Branch to Assist Yves Lamothe with a fuel igniter circuit. Yves Lamothe is an electrical engineer who is currently working on safe fuel combustion testing. This testing is planned to determine the minimum ignition energy for fuel and air vapors of current and alternative fuels under simulated flight conditions. An air temperature bath will provide simulated flight profile temperatures and the heat fluxes to the test chamber. I was assigned with Yves to help complete the igniter circuit which consists of a 36k voltage supply an oscilloscope, and a high voltage transistor switch. During my tenure in the L.E.C.I.R.P. program I studied the basics of electricity and circuitry along with two other projects that I completed. In the beginning of my internship, I devote all of my time to research the aspects of circuitry so that I would be prepared for the projects that I was assigned to do. I read about lessons on; the basic physical concepts of electronics, Electrical units, Basic dc circuits, direct current circuit analysis, resistance and cell batteries, various types of magnetism , Alternating current basics, inductance, and power supplies. I received work sheets and math equations from my Mentor so that I could be able to apply these concepts into my work. After I complete my studies, I went on to construct a LED chaser circuit which displays a series of light patterns using a 555 timer. I incorporated a switch and motion detector into the circuit to create basic alarm system. This project challenged my ability to interpret a schematic and expand it. While I was still completing the LED chaser circuit I Also was given A Basic Stamp Toddler Robot to build and program. The Toddler robot can walk in 36 various styles using advanced robotics. I used many different programs to create movement and direction of the robot. Also the Toddler can use infrared vision to sense objects. This enables the robot to maneuver indefinitely without running into objects. During my tenure at the NASA Glen Research Center I definite utilized the NASA mission to educate. I learned valuable information to help in my up coming year as a freshman in college.

Wemple, R.P.; Meyer, R.D.; Jacobson, R.D.

This work in partnership with industry is a continuation of cost- effective innovative, directional boring development begun in FY90 and planed to extend into FY94. Several demonstrations of the strategy of building hybrid hardware from utilities installation, geothermal, and soil mechanics technologies have been performed at Sandia National Laboratories (SNL) and at Charles Machine works (CMW) test sites as well as at a commercial refinery site. Additional tests at the SNL Directional Boring Test Range (DBTR) and a lagoon site are planned in calendar 1991. A new companion project to develop and demonstrate a hybrid capability for horizontal logging withmore » penetrometers, specialty instruments and samplers has been taken from concept to early prototype hardware. The project goal of extending the tracking/locating capability of the shallow boring equipment to 80in. is being pursued with encouraging results at 40in. depths. Boring costs, not including tailored well completions dictated by individual site parameters, are estimated at $20 to $50 per foot. Applications continue to emerge for this work and interest continues to be expressed by DoD and EPA researchers and environmental site engineers. 12 figs.« less

To describe nurses' perceptions of conditions for patient education, focusing on organisational, environmental and professional cooperation aspects, and to determine any differences between primary, municipal and hospital care. Although patient education is an important part of daily nursing practice, the conditions for this work are unclear and require clarification. A stratified random sample of 701 (83%) nurses working in primary, municipal and hospital care completed a 60-item questionnaire. The study is part of a larger project. The study items relating to organisation, environment and professional cooperation were analysed using descriptive statistics, non-parametric tests and content analysis. Conditions for patient education differ. Nurses in primary care had better conditions and more managerial support, for example in the allocation of undisturbed time. Conditions related to organisation, environment and cooperation need to be developed further. In this process, managerial support is important, and nurses must ask for better conditions in order to carry through patient education. Managerial support for the development of visible patient education routines (e.g. allocation of time, place and guidelines) is required. One recommendation is to designate a person to oversee educational work. © 2012 Blackwell Publishing Ltd.

The Port Granby Project is an integral part of the Port Hope Area Initiative (PHAI), and is located approximately 14 kilometres west of the Municipality of Port Hope in the adjacent Municipality of Clarington, Ontario. The principal objective of the project is the excavation and relocation of low-level radioactive waste (LLRW) and marginally contaminated soils, which were deposited at the Port Granby Waste Management Facility (PGWMF) by Eldorado Nuclear Limited during the period 1955 to 1988, to a new, highly engineered above-ground Long-term Waste Management Facility (LTWMF) to be constructed on a nearby site. The Environmental Assessment for the Projectmore » was approved in 2009 August and the required Waste Nuclear Substance License was received in 2011 November. Once the detailed engineering design was completed, in 2011 March, the Port Granby Project was divided into three major contracts for construction implementation purposes. The first of these contracts was completed in late 2012 and the second is planned to start in early 2013. The contracting process for the third major contract is also expected to be completed during 2013. This paper provides an overview of the Port Granby Project as well as discussion on the status of the Project, including the regulatory approvals process, the approach to contracting the construction works and an update of work recently completed and soon to get underway.

2015-02-01

The aim of this study is to investigate the level of burnout of clinical nurses and to examine the influence of personal and environmental factors on nurse burnout. A total of 717 full-time nurses from six hospitals in Tianjin, China, completed five questionnaires: a demographic questionnaire, the Maslach Burnout Inventory, the General Self-Efficacy Scale, the Practice Environment Scale of the Nursing Work Index and the Nurse Job Stressor Scale. The participants had moderate levels of emotional exhaustion (mean score 23.95 ± 11.11) and depersonalization (mean score 7.90 ± 6.58) and a high level of reduced personal accomplishment (mean score 27.51 ± 10.96). Both personal and environmental factors were correlated with nurse burnout; however, personal factors played bigger roles in predicting personal accomplishment, whereas environmental factors played bigger roles in predicting emotional exhaustion and depersonalization. In order to reduce nurse job burnout effectively, administrators should pay more attention to the improvement of nurses' self-efficacy and professional nursing practice environment and the reduction of stressors. © 2013 Wiley Publishing Asia Pty Ltd.

Urban environments offer students interesting opportunities to explore and examine how human modified landscapes influence biodiversity, nutrient cycling, and water quality. Students demanding applied field experiences from their undergraduate environmental science (ENVS) programs can be well served in urban settings. Here, we present strategies for integrating urban areas into the undergraduate field experience. Urban locations provide an opportunity for a different type of local "field-work" than would otherwise be available. In the intro level undergraduate ENVS class, we use our campus, the surrounding neighborhood and city as well as a nearby National Park for field exercises. Here we share lesson plans for field activities that can be completed with incoming undergraduate students, and show how these activities help students gain quantitative and investigative competency.

In recent years, owing to global warming and the rising sea levels, beach nourishment and groin building have been increasingly employed to protect coastal land from shoreline erosion. These actions may degrade beach habitats and reduce biomass and invertebrate density at sites where they were employed. We conducted an eco-environmental evaluation at the Anping artificial beach-nourishment project area. At this site, sand piles within a semi-enclosed spur groin have been enforced by use of eco-engineering concepts since 2003. Four sampling sites were monitored during the study period from July 2002 to September 2008. The environmental impact assessment and biological investigations that we conducted are presented here. The results from this study indicate that both biotic (number of species, number of individual organisms, and Shannon-Wiener diversity) and abiotic parameters (suspended solids, biological oxygen demand, chemical oxygen demand, dissolved inorganic nitrogen, dissolved inorganic phosphorus, total phosphorus, total organic carbon, median diameter, and water content) showed significant differences before and after beach engineering construction. Biological conditions became worse in the beginning stages of the engineering but improved after the restoration work completion. This study reveals that the composition of benthic invertebrates changed over the study period, and two groups of organisms, Bivalvia and Gastropoda, seemed to be particularly suitable to this habitat after the semi-enclosed artificial structures completion.

1997-12-01

An interdisciplinary environmental water quality study was designed and conducted to enhance training and employability of chemical and environmental technician students in associate degree programs. Four project objectives were identified as a means to enhance the educational experience and employability of our students: provide experience on analytical instrumentation for organic compounds (gas chromatography/mass spectrometry, GC/MS), require interdisciplinary group interactions and problem solving, provide experience with Environmental Protection Agency (EPA) procedures, and require cooperation with state agencies/private organizations. Students worked in groups that included representatives from both programs to develop project objectives and a Sampling and Analysis Plan (SAP) following EPA standards. Input from personnel at Idaho's Department of Environmental Quality and Bureau of Laboratories and from volunteers in an environmental "watch dog" organization called the Henry's Fork Foundation aided students in the development and implementation of their SAP. Subsequently, groups sampled sections of the Henry's Fork River and analyzed for organic, inorganic, and fecal contaminants. Analysis included EPA method 525.2 for pesticides using GC/MS. Data from all river segments was shared and each group submitted a final report analyzing results. Surveys completed by students and instructors indicate that the project is a successful teaching method allowing introduction of new skills as well as review of important technical and employability skills.

Environmental epigenetics: A promising venue for developing next-generation pollution biomonitoring tools in marine invertebrates.

Suarez-Ulloa, Victoria; Gonzalez-Romero, Rodrigo; Eirin-Lopez, Jose M

2015-09-15

Environmental epigenetics investigates the cause-effect relationships between specific environmental factors and the subsequent epigenetic modifications triggering adaptive responses in the cell. Given the dynamic and potentially reversible nature of the different types of epigenetic marks, environmental epigenetics constitutes a promising venue for developing fast and sensible biomonitoring programs. Indeed, several epigenetic biomarkers have been successfully developed and applied in traditional model organisms (e.g., human and mouse). Nevertheless, the lack of epigenetic knowledge in other ecologically and environmentally relevant organisms has hampered the application of these tools in a broader range of ecosystems, most notably in the marine environment. Fortunately, that scenario is now changing thanks to the growing availability of complete reference genome sequences along with the development of high-throughput DNA sequencing and bioinformatic methods. Altogether, these resources make the epigenetic study of marine organisms (and more specifically marine invertebrates) a reality. By building on this knowledge, the present work provides a timely perspective highlighting the extraordinary potential of environmental epigenetic analyses as a promising source of rapid and sensible tools for pollution biomonitoring, using marine invertebrates as sentinel organisms. This strategy represents an innovative, groundbreaking approach, improving the conservation and management of natural resources in the oceans. Copyright © 2015 Elsevier Ltd. All rights reserved.

Are modern health worries, environmental concerns, or paranormal beliefs associated with perceptions of the effectiveness of complementary and alternative medicine?

To investigate to what extent paranormal beliefs, modern health worries (MHWs), and environmental concerns were related to beliefs about, and behaviour associated with complementary and alternative medicine (CAM). Of the participants, 150 completed a four-part questionnaire measuring use and perception of CAM, MHWs, paranormal beliefs, and environmental concerns. A factor analysis on the CAM questions revealed three clear components, labelled efficacy of CAM, attitudes to CAM, and safety of CAM. Age, total MHWs, paranormal beliefs, and environmental concerns were used as predictor variables in regression analyses with efficacy as criterion variable. Age was found to be a significantly related to efficacy of CAM. When total MHW score, paranormal belief score, and environmental concern score were added to the model, the r(2) increased by 29%. Environmental concern did not significantly relate to efficacy but spiritualism beliefs did. A factor analysis of the MHW scale items revealed nine factors. Out of these, radiation, doctors playing God, disasters, and epidemics, as well as harmful rays and air contaminants significantly predict belief in the efficacy of CAM. Overall, older people, with more MHWs, and who believe in the paranormal are more likely to believe that CAM works, possibly because of a more intuitive, 'holistic', thinking style. Limitations of the study are considered.

The EM SSAB Annual Work Plan Process: Focusing Board Efforts and Resources - 13667

Young, Ralph

One of the most daunting tasks for any new member of a local board of the Environmental Management Site Specific Advisory Board (EM SSAB) is to try to understand the scope of the clean-up activities going on at the site. In most cases, there are at least two or three major cleanup activities in progress as well as monitoring of past projects. When planning for future projects is added to the mix, the list of projects can be long. With the clean-up activities involving all major environmental media - air, water, soils, and groundwater, new EM SSAB members can findmore » themselves totally overwhelmed and ineffective. Helping new members get over this initial hurdle is a major objective of EM and all local boards of the EM SSAB. Even as members start to understand the size and scope of the projects at a site, they can still be frustrated at the length of time it takes to see results and get projects completed. Many project and clean-up timelines for most of the sites go beyond 10 years, so it's not unusual for an EM SSAB member to see the completion of only 1 or 2 projects over the course of their 6-year term on the board. This paper explores the annual work planning process of the EM SSAB local boards, one tool that can be used to educate EM SSAB members into seeing the broader picture for the site. EM SSAB local work plans divide the site into projects focused on a specific environmental issue or media such as groundwater and/or waste disposal options. Projects are further broken down into smaller segments by highlighting major milestones. Using these metrics, local boards of the EM SSAB can start to quantify the effectiveness of the project in achieving the ultimate goal of site clean-up. These metrics can also trigger board advice and recommendations for EM. At the beginning of each fiscal year, the EM SSAB work plan provides a road map with quantifiable checkpoints for activities throughout the year. When the work plans are integrated with site-specific, enforceable regulatory milestones, they can provide a comprehensive work plan for not only the board, but also regulators, site contractors, and DOE. Because the work plans are reviewed and approved by DOE, they carry some weight in holding local boards of the EM SSAB accountable. This structure provides the basis for local boards to achieve their primary function, to provide DOE with information, advice, and recommendations concerning issues affecting the EM program at the site.

2013-01-01

The plant growth-promoting bacterium (PGPB) Pseudomonas sp. UW4, previously isolated from the rhizosphere of common reeds growing on the campus of the University of Waterloo, promotes plant growth in the presence of different environmental stresses, such as flooding, high concentrations of salt, cold, heavy metals, drought and phytopathogens. In this work, the genome sequence of UW4 was obtained by pyrosequencing and the gaps between the contigs were closed by directed PCR. The P. sp. UW4 genome contains a single circular chromosome that is 6,183,388 bp with a 60.05% G+C content. The bacterial genome contains 5,423 predicted protein-coding sequences that occupy 87.2% of the genome. Nineteen genomic islands (GIs) were predicted and thirty one complete putative insertion sequences were identified. Genes potentially involved in plant growth promotion such as indole-3-acetic acid (IAA) biosynthesis, trehalose production, siderophore production, acetoin synthesis, and phosphate solubilization were determined. Moreover, genes that contribute to the environmental fitness of UW4 were also observed including genes responsible for heavy metal resistance such as nickel, copper, cadmium, zinc, molybdate, cobalt, arsenate, and chromate. Whole-genome comparison with other completely sequenced Pseudomonas strains and phylogeny of four concatenated “housekeeping” genes (16S rRNA, gyrB, rpoB and rpoD) of 128 Pseudomonas strains revealed that UW4 belongs to the fluorescens group, jessenii subgroup.

No previous research has examined the importance of both individual and environmental factors for predicting caregivers' menstrual attitudes. To explore the predictors of female caregivers' attitudes towards menstruation and the help they give to women with intellectual disabilities, we conducted a cross-sectional questionnaire survey which was completed by 725 female workers from 12 institutions in Taiwan. The Menstrual Attitudes Questionnaire (MAQ) and a structured questionnaire were used. Logistic regression analysis revealed that individual characteristics such as age and education were significantly associated with menstrual attitudes of female caregivers working with institutionalized women with intellectual disabilities. Furthermore, the environmental context, such as the frequency of discussions with colleagues, training in menstrual management care and the level of difficulty when giving help in menstruation management, was important for improving caregivers' menstrual attitudes. This study contributes to the existing literature by determining both individual and environmental predictors of caregivers' menstrual attitudes.

Environmental controls and avoidance measures.

PubMed

Krouse, Helene J

2014-09-01

Environmental control measures refer to using 1 or more interventions aimed at avoiding, reducing, or eliminating allergens and irritants in the environment to improve symptoms of allergic rhinitis. Although avoiding known allergens is highly effective, completely eliminating an allergen from one's environment is often impractical or even impossible. The purpose of this work is to review evidence on the efficacy of various environmental control measures aimed at preventing the development of new sensitizations, reducing the progression of allergic rhinitis, and improving its symptoms and quality of life. Current literature examining the protective effects of specific measures such as breastfeeding and early pet exposure against the development of allergic diseases including allergic rhinitis has been inconclusive. Environmental measures such as frequently washing cats and dogs, encasing bedding within impermeable covers, air filtration, and chemicals can effectively reduce levels of allergens in the home. Although environmental control measures reduce allergen exposure levels, significant alleviation in symptoms or improvement in quality of life in patients with allergic rhinitis have not been shown. An evidence-based approach can assist health providers in educating patients and helping them to make informed decisions in selecting the most appropriate and cost-effective environmental control strategies to manage their disease. The greatest benefits can be achieved from using a multifaceted environmental approach aimed at routinely and systematically reducing exposure to allergens over time. © 2014 ARS-AAOA, LLC.

Built environment is an important social determinant of health, but nowadays local health authorities (LHAs) have lost their competences in the issuing of building permits, especially since a new legislation introduced the possibility of personal declaration of conformity. They are also usually excluded from the urban planning process. At the same time, in recent years construction of buildings has been developed with insufficient regard to environmental health requirements, proper exposure to sunlight and winds, comfort, building materials, consumption of resources, and waste production. To deal with these issues, an interdepartmental working group was set up under the direction of the Department of Prevention of the LHA of Empoli (Tuscany Region, Central Italy), with members of the Regional Environmental Protection Agency, along with experts of the 15 Municipalities included in the LHA territory and members of other local institutions. The objective of the Working Group was to define and propose as mandatory a set of rules for local governments aimed at regulating construction activities according to criteria of environmental sustainability, eco-efficiency, comfort, and healthiness of living areas, at the same time encouraging the responsible use of natural resources, the reduction of energy consumption and the use of renewable energy sources in order to place environmental safety and health at the heart of all building activities. Experts of six Municipalities joined the working group and the regulation framework was adopted (and made legally binding) in 8 out of 15 Municipalities, with an almost complete overlap with participation in the working group. The active participation of experts, whose work consists in examining municipal building, permits, and declarations, has therefore marked the difference in the transition from theory to practice. The level of know-how attained by the participants and their motivation and enthusiasm have been so relevant in the whole project that we think this procedure could be successfully used in other fields of inter-institutional activities.

The purpose of the Isotopes Facilities Deactivation Project (IFDP) is to place former isotopes production facilities at the Oak Ridge National Laboratory in a safe, stable, and environmentally sound condition; suitable for an extended period of minimum surveillance and maintenance (S and M) and as quickly and economical as possible. Implementation and completion of the deactivation project will further reduce the risks to the environment and to public safety and health. Furthermore, completion of the project will result in significant S and M cost savings in future years. The IFDP work plan defines the project schedule, the cost estimate, andmore » the technical approach for the project. A companion document, the EFDP management plan, has been prepared to document the project objectives, define organizational relationships and responsibilities, and outline the management control systems to be employed in the management of the project. The project has adopted the strategy of deactivating the simple facilities first, to reduce the scope of the project and to gain experience before addressing more difficult facilities. A decision support system is being developed to identify the activities that best promote the project mission and result in the largest cost savings. This work plan will be reviewed and revised annually. Deactivation of EFDP Facilities was initiated in FY 1994 and will be completed in FY 2000. The schedule for deactivation of facilities is shown. The total cost of the project is estimated to be $51M. The costs are summarized. Upon completion of deactivation, annual S and M costs of these facilities will be reduced from the current level of $5M per year to less than $1M per year.« less

Developing an Ecological Passport for an Open-Pit Dump Truck to Reduce Negative Effect on Environment

NASA Astrophysics Data System (ADS)

Koptev, V. Yu; Kopteva, A. V.

2017-05-01

Expanding the open-pit dump truck usage areas and the need to transport more and more minerals results in producing more and more powerful open-pit dump trucks, and this all is about environmental problems and potential health risks for the personnel. Harmful gas concentrations in working areas became threatening enough to have the work in some areas completely halted, until the contents of harmful substances in the air, as well as visibility on the roads, get back to norm. The article represents the new methodology for assessing comparatively the efficiency of modern transportation systems with performance and ecology characteristics taken into account, by developing an ecological passport for machines, facilitating design improvements and reducing pollution during operation.

AIM—To determine the relation of refractive error to environmental factors, including close up work, in Singapore military conscripts.
METHODS—A cross sectional study was conducted on 429 Singapore military conscripts. Non-cycloplegic refraction and A-scan biometry were performed in both eyes. A detailed questionnaire was administered by in-person interview to obtain information about current and past near work activity, extra tuition lessons, educational experiences, and family demographics.
RESULTS—Myopia associated with the conscript having been educated in the (gifted, special, or express) educational streams (adjusted odds ratio (OR) = 3.8, 95% confidence interval CI 2.0-7.3), and having completed pre-university education (OR=4.1, 95% CI 1.9-8.8). The reported close up work activity at age 7 years did correlate with age of onset of myopia (p<0.001). In parallel, supplemental tuition lessons in primary school has (OR=2.6, 95% CI 1.4-4.9) associated with conscript myopia. Parental myopia was positively associated with myopia (p<0.001), but this relation disappeared when adjusted for environmental factors. Current (p=0.83) and past close up work activity at age 7 years (p=0.13) did not correlate with myopia.
CONCLUSION—Educational level and educational stream positively related to myopia. A relation was observed with reported close up work activity in early childhood and with tuition classes during elementary school, but not with current close up work activity. These results underscore the strong influence of environment in myopia pathogenesis but a role for close up work activity remains indeterminate.

Occupational risk factors in inflammatory bowel disease.

PubMed

Leso, V; Ricciardi, W; Iavicoli, I

2015-08-01

Crohn's disease and ulcerative colitis are the two main forms of inflammatory bowel disease (IBD). Although the aetiology of IBD is not completely understood, an interaction between genetic and environmental factors has been proposed. In this context, however, environmental epidemiology lacks a comprehensive evaluation of the possible role of occupational exposures in IBD development and progression. Therefore, aim of our review was to evaluate how certain occupational risk factors may affect IBD pathogenesis, clinical history and severity of disease manifestations. A critical revision of available literature concerning exposure to groups of potential workplace hazardous agents and IBD, as it appears in Medline and Web of knowledge, was performed. The role of workplace exposures to chemical and biological agents, ionizing or non-ionizing radiations, shift-works, indoor, and sedentary works as well as job strain on IBD has been critically revised. However, the limited number of studies addressing these issues prevented us from extrapolating definite conclusions. Our review pointed out some critical aspects concerning the relationship between occupational factors and IBD, in terms of causative pathways, hazardous exposure, susceptibility and consequences of IBD functional limitations on career choice and fitness for work that need future investigations. Overall, this seems a challenging public health issue, considering the strong IBD impact on patients' quality of life, work productivity and costs to society. Moreover, this review may encourage concerted actions of health care specialists, occupational physicians, employers and IBD workers to plan preventive and protective measures for "healthier patterns of work" for IBD and to develop innovative perspectives for an integrated management of "IBD at work".

Contingency Management with Human Autonomy Teaming

Shively, Robert J.; Lachter, Joel B.

2018-01-01

Automation is playing an increasingly important role in many operations. It is often cheaper faster and more precise than human operators. However, automation is not perfect. There are many situations in which a human operator must step in. We refer to these instances as contingencies and the act of stepping in contingency management. Here we propose coupling Human Autonomy Teaming (HAT) with contingency management. We describe two aspects to HAT, bi-directional communication, and working agreements (or plays). Bi-directional communication like Crew Resource Management in traditional aviation, allows all parties to contribute to a decision. Working agreements specify roles and responsibilities. Importantly working agreements allow for the possibility of roles and responsibilities changing depending on environmental factors (e.g., situations the automation was not designed for, workload, risk, or trust). This allows for the automation to "automatically" become more autonomous as it becomes more trusted and/or it is updated to deal with a more complete set of possible situations. We present a concrete example using a prototype contingency management station one might find in a future airline operations center. Automation proposes reroutes for aircraft that encounter bad weather or are forced to divert for environmental or systems reasons. If specific conditions are met, these recommendations may be autonomously datalinked to the affected aircraft.

This program is being conducted as a cooperative agreement between the Consortium for Coal Water Mixture Technology and the U.S. Department of Energy. Activities this reporting period are summarized by phase. Phase I is nearly completed. During this reporting period, coal beneficiation/preparation studies, engineering designs and economics for retrofitting the Crane, Indiana boiler to fire coal-based fuels, and a 1,000-hour demonstration of dry, micronized coal were completed. In addition, a demonstration-scale micronized-coal water mixture (MCWM) preparation circuit was constructed and a 1,000-hour demonstration firing MCWM began. Work in Phase II focused on emissions reductions, coal beneficiation/preparation studies, and economic analysesmore » of coal use. Emissions reductions investigations involved literature surveys of NO{sub x}, SO{sub 2}, trace metals, volatile organic compounds, and fine particulate matter capture. In addition, vendors and engineering firms were contacted to identify the appropriate emissions technologies for the installation of commercial NO{sub x} and SO{sub 2} removal systems on the demonstration boiler. Information from the literature surveys and engineering firms will be used to identify, design, and install a control system(s). Work continued on the refinement and optimization of coal grinding and MCWM preparation procedures, and on the development of advanced processes for beneficiating high ash, high sulfur coals. Work also continued on determining the basic cost estimation of boiler retrofits, and evaluating environmental, regulatory, and regional economic impacts. In addition, the feasibility of technology adoption, and the public`s perception of the benefits and costs of coal usage was studied. A coal market analysis was completed.

It is important to remember that personal actions and decisions have a significant impact on the environment. Although they may sometimes forget, today`s school children are the policy and decision makers of tomorrow. Today`s students must be exposed to factual information about the environment so they will be able to make responsible and informed ecological decisions. Since the National Environmental Education Act was signed into law in 1990, the Environmental Protection Agency (EPA) has taken an active role in ensuring a sustainable future through environmental education. Through its education programs, the EPA strives to increase environmental literacy throughout the countrymore » and encourages young people to pursue careers in math, science, engineering, communications, and other fields essential to a sustainable environment. The US Environmental Protection Agency`s Office of Air Quality Planning and Standards (OAQPS), located in Research Triangle Park, North Carolina, is an international center for air quality research and information. One of the ways OAQPS invests in the environmental preservation of the Nation is through unique environmental education programs that target teachers and students of all ages. To be sure that environmental education programs incorporate a complete look at the environment, including issues associated with air quality, the EPA works with North Carolina teachers and students through the Education and Outreach Group`s Environmental Education Program. The EPA recognizes that the key to a sustainable future is engaging teachers and others in significant environmental education experiences. They will in turn instill a sense of environmental stewardship in America`s young people. There is hope that by the year 2000, every citizen will be fluent in the principles of ecology.« less

Given the limited studies on emergency care management, this study aimed to explore the relationships of emergency department (ED) culture values to certain dimensions of ED physicians' and nurses' work satisfaction and intent to leave. Four hundred and forty-two emergency medical professionals completed the employee satisfaction questionnaire across 119 hospital-based EDs, which had culture value evaluations filed, were used as unit of analysis in this study. Adjusting the personal and employment backgrounds, and the surrounded EDs' unit characteristics and environmental factors, multiple regression analyses revealed that clan and market cultures were related to emergency physicians' work satisfaction and intent to leave. On the other hand, adhocracy, market and hierarchical cultures were related to emergency nurses' work satisfaction. There do exist different patterns among various culture types on various work satisfaction dimensions and intent to leave of emergency physicians and nurses. The findings could offer hospital and ED leaders insights for changes or for building a better atmosphere to enhance the work life of emergency physicians and nurses.

Cristancho, María Yanire León

2012-01-01

The objective of this paper was to control ergonomic risks among female cashiers working in a department store belonging to the retail market. This study was conducted between May and November 2010. Participatory ergonomics was applied through knowing and understanding how the company works, establishing the work team (Ergo group), training the team in ergonomics-related topics, and making decisions and interventions. The sample was composed of 71 participants--mostly female cashiers--, and all of them have a musculoskeletal compromise, declaring pain or discomfort mainly in the neck, lower back, right wrist and shoulders. Among others, following problems were found: postural overload, repetitive work, manual load handling, mental fatigue, environmental discomfort, variable work schedules, extended working days, and absence of breaks. In the intervention, the main implemented changes were the redesign of workstation, complete change of chairs and keyboards, and the implementation of a rotation system, as well breaks for compensatory exercises. After that, an evident improvement of found problems was observed, therefore it can be concluded that participatory ergonomics is an attractive methodology, appropriate and efficient for solving and controlling ergonomic risks and problems.

Iron Mountain Mine is located seventeen miles northwest of Redding, CA. After the completion of mining in early 1960s, the mine workings have been exposed to environmental elements which have resulted in degradation in water quality in the surrounding water sheds. In 1985, the EPA plugged ore stoops in many of the accessible mine drifts in an attempt to restrict water flow through the mine workings. During this process little data was gathered on the orientation of the stoops and construction of the plugs. During the last 25 years, plugs have begun to deteriorate and allow acidic waters from themore » upper workings to flow out of the mine. A team from Idaho National Laboratory (INL) performed geophysical surveys on a single mine drift and 3 concrete plugs. The project goal was to evaluate several geophysical methods to determine competence of the concrete plugs and orientation of the stopes.« less

Family routines within the ecological niche: an analysis of the psychological well-being of U.S. caregivers of children with disabilities

2014-01-01

Using mixed methods, this study examined the relationship of caregivers of children with disabilities’ psychological well-being (PWB) and their orchestration of daily routines within their ecological niche. Thirty-nine U.S. caregivers completed in-depth interviews, PWB Scales, and Family Time and Routines Index (FTRI). We used a multi-step analysis. Interview data was coded and vignettes created without knowledge of PWB and FTRI ratings. Next, the relationship of quantitative measures was analyzed. Four groups were created using FTRI-extent and PWB means: (1) low routine-low PWB, (2) low routine-high PWB, (3) high routine-low PWB, and (4) high routine-high PWB. We examined qualitative differences in key features between groups. Findings: Total PWB and FTRI scores were not significantly correlated, PWB Purpose in Life and FTRI-extent scores were moderately positively correlated, and PWB Environmental Mastery and FTRI-extent correlation approached significance. Qualitative findings describe caregivers’ structuring of routines, intensity of oversight, support in routines, management of dinner, paid work, and needs for respite. The four groups differed in paid work, household support, degree the child could self-occupy, Environmental Mastery, and opportunities to recuperate. Caregivers with higher levels of well-being and more regular routines did paid work, had supportive spouses, had children who more often could follow routines, had higher Environmental Mastery, could orchestrate a family meal, and had breaks from care in either work or leisure. All Native American caregivers and Mexican American caregivers with spouses were in the high routine-high PWB group. Insight into this complex negotiation between family members within daily routines may provide practitioners a better understanding of how to work within family circles to foster therapeutic alliances, identify focused intervention targets, and promote positive family wide outcomes.

Created in 1989 to address over 50 years of environmental liabilities arising out of nuclear weapons production and testing in the United States since World War II, the U.S. Department of Energy's (DOE's) Environmental Management (EM) Programs decade-long effort to reduce the costs of those environmental liabilities, collectively known as DOE's ''environmental mortgage,'' includes past as well as future cleanup costs associated with environmental contamination, hazardous and radioactive materials and wastes, contaminated buildings and facilities, and their associated risks. Tasked with the bulk of these cleanup efforts, the U.S. Department of Energy, Nevada Operations Office's (DOE/NV's), Nevada Environmental Restoration Projectmore » (NV ERP) is attempting to complete applicable corrective actions at inactive contaminated sites and facilities managed by DOE/NV, while at the same time protecting human health and the environment. Regulated under the Federal Facility Agreement and Consent Order, the objectives of the NV ERP are to identify the nature and extent of the contamination, determine its potential risk to the public and the environment, and to perform the necessary corrective actions in compliance with this and other state and federal regulations, guidelines, and requirements. Associated with this vast effort are approximately 2,000 sites both on and off of the Nevada Test Site (NTS) that were used primarily for nuclear testing and are addressed in the NV ERP. This includes sites that were underground areas where tests were actually conducted, contaminated surface soils resulting from aboveground testing activities, and sites that supported other related testing hardware paraphenalia and/or NTS real estate properties (e.g., underground storage tanks, leachfields, landfills, contaminated waste areas, injection wells, muckpiles, and ponds). To assist in this effort, a NV ERP Team was assembled which is composed of organizations from both the public and private sectors. The strategy to be employed for environmental restoration is based on commonality of work and the DOE EM Program's vision to remediate the contaminated sites on a project-specific, site-by-site basis over an approximate ten-year period to be completed by the year 2006.« less

Environmental supports for walking/biking and traffic safety: income and ethnicity disparities.

PubMed

Yu, Chia-Yuan

2014-10-01

The present study investigates the influence of income, ethnicity, and built environmental characteristics on the percentages of workers who walk/bike as well as on pedestrian/cyclist crash rates. Furthermore, income and ethnicity disparities are also explored. This study chose 162 census tracts in Austin as the unit of analysis. To explore income and ethnicity differences in built environments, this study examined the associations of the poverty rate, the percentage of white population, and the percentage of Hispanic population to each built environmental variable. Path models were applied to examine environmental supports of walking/biking and pedestrian/cyclist safety. Areas with high poverty rates had more biking trips and experienced more cyclist crashes, while areas with a high percentage of white population generated more walking trips and fewer pedestrian crashes. Sidewalk completeness and mixed land uses promoted walking to work but increased the crash risk for pedestrians as well. In terms of biking behaviors, road density and transit stop density both increased biking trips and cyclist crashes. Environmental designs that both encourage walking/biking trips and generate more safety threats should attract more attention from policy makers. Policies should also be more devoted to enhancing the mobility and health for areas with high poverty rates. Copyright © 2014 Elsevier Inc. All rights reserved.

Healthy e-health? Think 'environmental e-health'!

2010-01-01

The Environmental e-Health Research and Training Program has completed its scoping study to understand the breadth of a new field of research: Environmental e-Health. Nearly every aspect of modern life is associated, directly or indirectly, with application of technology, from a cup of coffee, through transportation to and from work, to appliances in the home and industrial activities. In recent decades the rapidly increasing application of information and communications technologies (ICT) has added to the cacophony of technological 'noise' around us. Research has shown that technology use, including ICTs, has impact upon the environment. Studying environmental impact in such a complex global setting is daunting. e-Health is now being used as a convenient microcosm of ICT application within which to study these impacts, and is particularly poignant given that e-Health's environmental harms conflict with its noble goals of 'doing no harm'. The study has identified impacts, both benefits and harms in all three life-cycle phases for e-Health: up-stream (materials extraction, manufacturing, packaging, distribution), mid-stream (use period), and down-stream (end-of-life processes--disposal, recycling). In addition the literature shows that a holistic 'Life Cycle Assessment' approach is essential to understand the complexity of the setting, and determine the true balance between total harms and total benefits, and for whom.

The majority of studies show a substantially higher consumption of anxiolytics and antidepressants among women than among men and in the age bracket above 45 years. To analyse association between the use of hypnotics/anxiolytics, and various characteristics of Polish women, including health-related quality of life. One thousand, five hundred and sixty (1,560) women aged 45-60 years completed a questionnaire dealing with the use of hypnotics/anxiolytics, demographic characteristics, environmental and work stress exposure, and self-reported quality of life (SF-36 form). The following variables were revealed as the predictors of hypnotic/anxiolytic use on univariate analysis: age; social pension; stress at work and environmental stress; hormone replacement therapy; headache; palpitations; mood swings or increased muscular tension; anger; duration of symptoms longer than one week; consulting a specialist; and low physical and mental health-related quality of life. The significant protective factors included: vocational and tertiary education; job satisfaction; and home as place of rest. The independent predictors of anxiolytic/hypnotic use included consulting a specialist and symptoms lasting more than one week, while job satisfaction and home as place of rest were the independent protective factors. The use of hypnotic/anxiolytic medication is strongly associated with environmental and psychosocial characteristics of women between 40 and 65 years of age.

Application of adenylate energy charge to problems of environmental impact assessment in aquatic organisms

NASA Astrophysics Data System (ADS)

Ivanovici, A. M.

1980-03-01

Various physiological and biochemical methods have been proposed for assessing the effects of environmental perturbation on aquatic organisms. The success of these methods as diagnostic tools has, however, been limited. This paper proposes that adenylate energy charge overcomes some of these limitations. The adenylate energy charge (AEC) is calculated from concentrations of adenine nucleotides ([ATP+½ADP]/[ATP+ADP+AMP]), and is a reflection of metabolic potential available to an organism. Several features of this method are: correlation of specific values with physiological condition or growth state, a defined range of values, fast response times and high precision. Several examples from laboratory and field experiments are given to demonstrate these features. The test organisms used (mollusc species) were exposed to a variety of environmental perturbations, including salinity reduction, hydrocarbons and low doses of heavy metal. The studies performed indicate that the energy charge may be a useful measure in the assessment of environmental impact. Its use is restricted, however, as several limitations exist which need to be fully evaluated. Further work relating values to population characteristics of multicellular organisms needs to be completed before the method can become a predictive tool for management.

2017-12-01

This needs assessment was initially undertaken to explore the beliefs and knowledge of nurses and physicians about the impact of environmental toxicants on maternal and infant health, as well as to describe current practice and needs related to addressing environmental health issues (EHI). One hundred and thirty-five nurses (n = 99) and physicians (n = 36) working in Saskatchewan completed an online survey. Survey questions were designed to determine how physicians and nurses think about and incorporate environmental health issues into their practice and means of increasing their capacity to do so. Although participants considered it important to address EHIs with patients, in actual practice they do so with only moderate frequency. Participants reported low levels of knowledge about EHIs' impact on health, and low levels of confidence discussing them with patients. Participants requested additional information on EHIs, especially in the form of online resources. The results suggests that while nurses and physicians consider EHIs important to address with patients, more education, support, and resources would increase their capacity to do so effectively. Based on the findings, considerations and recommendations for continuing education in this area have been provided.

Utilizing Urban Environments for Effective Field Experiences

Research surveys suggest that students are demanding more applied field experiences from their undergraduate environmental science programs. For geoscience educators at liberal arts colleges without field camps, university vehicles, or even geology departments, getting students into the field is especially rewarding - and especially challenging. Here, we present strategies that we have used in courses ranging from introductory environmental science for non-majors, to upper level environmental methods and geology classes. Urban locations provide an opportunity for a different type of local "field-work" than would otherwise be available. In the upper-level undergraduate Environmental Methods class, we relied on a National Park area located a 10-minute walk from campus for most field exercises. Activities included soil analysis, measuring stream flow and water quality parameters, dendrochronology, and aquatic microbe metabolism. In the non-majors class, we make use of our urban location to contrast water quality in parks and highly channelized urban streams. Here we share detailed lesson plans and budgets for field activities that can be completed during a class period of 2.5 hours with a $75 course fee, show how these activities help students gain quantitative competency, and provide student feedback about the classes and activities.

On August 1, 2011, URS - CH2M Oak Ridge LLC (UCOR) began its five-year, $1.4 billion cleanup of the East Tennessee Technology Park (ETTP), located on the U.S. Department of Energy's (DOE) Oak Ridge Reservation in Tennessee. UCOR will close out cleanup operations that began in 1998 under a previous contract. When the Contract Base scope of work [1] is completed in 2016, the K-25 gaseous diffusion building will have been demolished and all waste dispositioned, demolition will have started on the K-27 gaseous diffusion building, all contact-handled and remote-handled transuranic waste in inventory (approximately 500 cubic meters) will havemore » been transferred to the Transuranic Waste Processing Center, previously designated 'No-Path-To-Disposition Waste' will have been dispositioned to the extent possible, and UCOR will have managed DOE Office of Environmental Management (EM)- owned facilities at ETTP, Oak Ridge National Laboratory (ORNL), and the Y-12 National Security Complex in a safe and cost-effective manner. Since assuming its responsibilities as the ETTP cleanup contractor, UCOR has completed its life-cycle Performance Measurement Baseline; received its Earned Value Management System (EVMS) certification; advanced the deactivation and demolition (D and D) of the K-25 gaseous diffusion building; recovered and completed the Tank W-1A and K-1070-B Burial Ground remediation projects; characterized, packaged, and shipped contact-handled transuranic waste to the Transuranic Waste Processing Center; disposed of more than 90,000 cubic yards of cleanup waste while managing the Environmental Management Waste Management Facility (EMWMF); and provided operations, surveillance, and maintenance activities at DOE EM facilities at ETTP, ORNL, and the Y-12 National Security Complex. Project performance as of December 31, 2012 has been excellent: - Cost Performance Index - 1.06; - Schedule Performance Index - 1.02. At the same time, since safety is the foundation of all cleanup work, UCOR's safety record goes hand in hand with its excellent project performance. Through calendar year 2012, UCOR's recordable injury rate was 0.33, and the company has worked close to 4 million hours without a lost work day injury. UCOR's safety record is one of the best in the DOE EM Complex. This performance was due, in large part, to the people and processes URS and CH2M HILL, the parent companies of UCOR, brought to the project. Key approaches included: - Selected and deployed experienced staff in key leadership positions throughout the organization; - Approached 'Transition' as the 'true' beginning of the cleanup project - kicking off a number of project initiatives such as Partnering, PMB development, D and D Plan execution, etc. - Established a project baseline for performance measurement and obtained EVMS certification in record time; - Determined material differences and changed conditions that warranted contract change - then quickly addressed these changes with the DOE client; - Aligned the project and the contract within one year - also done in record time; - Implemented Safety Trained Supervisor and Safety Conscious Work Environment Programs, and kicked off the pursuit of certification under DOE's Voluntary Protection Program.

Shiftwork has been associated with elevated blood pressure (BP) and decreased heart-rate variability (HRV), factors that may increase the long-term risk of cardiovascular-related mortality and morbidity. This study explored the effect of shiftwork on dynamic changes in autonomic control of HRV (cardiac stress), systolic BP and diastolic BP, i.e., SBP and DBP (vascular stress), and recovery in the same subjects working different shifts. By studying the same subjects, the authors could reduce the effect of possible contribution of between-subject variation from genetic predisposition and environmental factors. The authors recruited 16 young female nurses working rotating shifts--day (08:00-16:00 h), evening (16:00-00:00 h), and night (00:00-08:00 h)--and 6 others working the regular day shift. Each nurse received simultaneous and repeated 48-h ambulatory electrocardiography and BP monitoring during their work day and the following off-duty day. Using a linear mixed-effect model to adjust for day shift, the results of the repeated-measurements and self-comparisons found significant shift differences in vascular stress. While working the night shift, the nurses showed significant increases in vascular stress, with increased SBP of 9.7 mm Hg. The changes of SBP and DBP seemed to peak during waking time at the same time on the day off as they did on the working day. Whereas HRV profiles usually returned to baseline level after each shift, the SBP and DBP of night-shift workers did not completely return to baseline levels the following off-duty day (p < .001). The authors concluded that although the nurses may recover from cardiac stress the first day off following a night shift, they do not completely recover from increases in vascular stress on that day.

Report of the Plasma Physics and Environmental Perturbation Laboratory (PPEPL) working groups. Volume 1: Plasma probes, wakes, and sheaths working group

It is shown in this report that comprehensive in-situ study of all aspects of the entire zone disturbance caused by a body in a flowing plasma resulted in a large number if requirements on the shuttle-PPEPL facility. A large amount of necessary in-situ observation can be obtained by adopting appropriate modes of performing the experiments. Requirements are indicated for worthwhile studies, of some aspects of the problems, which can be carried out effectively while imposing relatively few constraints on the early missions. Considerations for the desired growth and improvement of the PPEPL to facilitate more complete studies in later missions are also discussed. For Vol. 2, see N74-28170; for Vol# 3, see N74-28171.

Systems biology is a comprehensive means of creating a complete understanding of how all components of an organism work together to maintain and procreate life. By quantitatively profiling one at a time, the effect of thousands and millions of genetic and environmental perturbations on the cell, systems biologists are attempting to recreate and measure the effect of the many different states that have been explored during the 3 billion years in which life has evolved. A key aspect of this work is the development of innovative new approaches to quantify changes in the transcriptome, proteome, and metabolome. In this chapter we provide a review and evaluation of several genomic profiling techniques used in plant systems biology as well as make recommendations for future progress in their use and integration.

Policy, systems, and environmental approaches are recommended for preventing childhood obesity. The objective of our study was to evaluate the Healthy Lifestyles Initiative, which aimed to strengthen community capacity for policy, systems, and environmental approaches to healthy eating and active living among children and families. The Healthy Lifestyles Initiative was developed through a collaborative process and facilitated by community organizers at a local children's hospital. The initiative supported 218 partners from 170 community organizations through training, action planning, coalition support, one-on-one support, and the dissemination of materials and sharing of resources. Eighty initiative partners completed a brief online survey on implementation strategies engaged in, materials used, and policy, systems, and environmental activities implemented. In accordance with frameworks for implementation science, we assessed associations among the constructs by using linear regression to identify whether and which of the implementation strategies were associated with materials used and implementation of policy, systems, and environmental activities targeted by the initiative. Each implementation strategy was engaged in by 30% to 35% of the 80 survey respondents. The most frequently used materials were educational handouts (76.3%) and posters (66.3%). The most frequently implemented activities were developing or continuing partnerships (57.5%) and reviewing organizational wellness policies (46.3%). Completing an action plan and the number of implementation strategies engaged in were positively associated with implementation of targeted activities (action plan, effect size = 0.82; number of strategies, effect size = 0.51) and materials use (action plan, effect size = 0.59; number of strategies, effect size = 0.52). Materials use was positively associated with implementation of targeted activities (effect size = 0.35). Community-capacity-building efforts can be effective in supporting community organizations to engage in policy, systems, and environmental activities for healthy eating and active living. Multiple implementation strategies are likely needed, particularly strategies that involve a high level of engagement, such as training community organizations and working with them on structured action plans.

Benzene, an important component in gasoline, is a widely distributed environmental contaminant that has been linked to known health effects in animals and humans, including leukemia. In Mexico City, environmental benzene levels, which may be elevated because of the heavy traffic and the poor emission control devices of older vehicles, may pose a health risk to the population. To assess the potential risk, portable passive monitors and blood concentrations were used to survey three different occupational groups in Mexico City. Passive monitors measured the personal exposure of 45 workers to benzene, ethylbenzene, toluene, o-xylene and m-/p-xylene during a work shift. Blood concentrations of the above volatile organic compounds (VOCs), methyl tert-butyl ether, and styrene were measured at the beginning and the end of a work shift. Passive monitors showed significantly higher (p > 0.0001) benzene exposure levels among service station attendants (median = 330 microg/m3; range 130-770) as compared to street vendors (median = 62 microg/m3; range 49-180) and office workers (median = 44 microg/m3, range 32-67). Baseline blood benzene levels (BBLs) for these groups were higher than those reported for similar populations from Western countries (median = 0.63 microg/L, n = 24 for service station attendants; median = 0.30 microg/L, n = 6 for street vendors; and median = 0.17 microgr;g/L, n = 7 for office workers). Nonsmoking office workers who were nonoccupationally exposed to VOCs had BBLs that were more than five times higher than those observed in a nonsmoking U.S. population. BBLs of participants did not increase during the work shift, suggesting that because the participants were chronically exposed to benzene, complex pharmacokinetic mechanisms were involved. Our results highlight the need for more complete studies to assess the potential benefits of setting environmental standards for benzene and other VOCs in Mexico. Images Figure 1 PMID:10378996

Burnout in psychiatric nursing: examining the interplay of autonomy, leadership style, and depressive symptoms.

PubMed

Madathil, Renee; Heck, Nicholas C; Schuldberg, David

2014-06-01

It is important to consider ways in which nurses can be protected from experiencing the effects of burnout. This study examined the relationships between leadership style of psychiatric nurse supervisors, work role autonomy, and psychological distress in relation to psychiatric nurse burnout. Eighty-nine psychiatric nurses from Montana and New York hospitals completed an online survey that assessed their work-related experiences. Overall, results of this study indicate that the participants were experiencing high levels of emotional exhaustion and depersonalization when compared to a normative sample of mental health workers. Results also showed that leadership style and work role autonomy are likely to be environmental factors that protect against burnout in nurses. Finally, it was shown that the relationship between depressive symptoms and the burnout component of personal accomplishment may be influenced by nurses' perceptions of the leadership style in their work environment. These findings are important because nurse supervisor leadership styles and amount of autonomy are characteristics of the work environment that may be amenable to change through training and intervention.

Ramos, Ana; Rouboa, Abel

2018-05-01

Within the most used Waste-to-Energy technologies plasma gasification is recent and therefore not yet widely commercialized. Thus, it is necessary to conduct a viability study to support the thorough understanding and implementation of this thermal treatment. This paper aims to assess some technical, environmental and economic aspects of plasma gasification paving the way for a more sustained waste management system, as well as taking advantage of the commodity assets granted by the technique. Therefore, results from previously published studies were updated and highlighted as a preliminary starting point in order to potentially evolve to a complete and systematic work.

Final Research Performance Progress Report: Geothermal Resource Development with Zero Mass Withdrawal, Engineered Convection, and Wellbore Energy Conversion

DOE Office of Scientific and Technical Information (OSTI.GOV)

Hughes, Richard; Tyagi, Mayank; Radonjic, Mileva

This project is intended to demonstrate the technical and economic feasibility, and environmental and social attractiveness of a novel method of heat extraction from geothermal reservoirs. The emphasis is on assessing the potential for a heat extraction method that couples forced and free convection to maximize extraction efficiency. The heat extraction concept is enhanced by considering wellbore energy conversion, which may include only a boiler for a working fluid, or perhaps a complete boiler, turbine, and condenser cycle within the wellbore. The feasibility of this system depends on maintaining mechanical and hydraulic integrity of the wellbore, so the material propertiesmore » of the casing-cement system are examined both experimentally and with well design calculations. The attractiveness depends on mitigation of seismic and subsidence risks, economic performance, environmental impact, and social impact – all of which are assessed as components of this study.« less

Rural areas generate a large amount of plant and animal residues that can be recycled and utilized instead of relocation and/or burning. This will lead to increasing the benefits from agricultural sector in rural communities and ensuring a better environment. To increase the economic output and environmental benefits of recycling agricultural residues, integrated system should be considered, e.g., energy--compost-recycled water system; composting--co-composting system; food-feed compost system, ensilage of crop residues. The present work was a pilot study for optimizing integrated systems for bioconversion agricultural residues completed by establishing a Training Center for Recycling Agricultural Residues (TCRAR) thereby ensuring the dissemination of the technical, environmental, and socioeconomic aspects to farmers, live stock producers, extensions service staff, and private sector. Three integrated subsystems for bioconversion of agricultural residues were developed. They were based on (i) energy--manure-recycled water system, (ii) composting and co-composting system, and (iii) food-feed/compost system.

Indoor air-assessment: Indoor concentrations of environmental carcinogens

In the report, indoor concentration data are presented for the following general categories of air pollutants: radon-222, environmental tobacco smoke (ETS), asbestos, gas phase organic compounds, formaldehyde, polycyclic aromatic hydrocarbons (PAH), pesticides, and inorganic compounds. These pollutants are either known or suspect carcinogens (i.e., radon-222, asbestos) or more complex mixtures or classes of compounds which contain known or suspect carcinogens. Concentration data for individual carcinogenic compounds in complex mixtures are usually far from complete. The data presented for complex mixtures often include compounds which are not carcinogenic or for which data are insufficient to evaluate carcinogenicity. Their inclusion is justified,more » however, by the possibility that further work may show them to be carcinogens, cocarcinogens, initiators or promotors, or that they may be employed as markers (e.g., nicotine, acrolein) for the estimation of exposure to complex mixtures.« less

Kleptoplast Regulation by an Antarctic Dinoflagellate

NASA Astrophysics Data System (ADS)

Gast, R. J.; Hehenberger, E.; Keeling, P.

2016-02-01

We are studying the evolutionary history and expression of plastid- targeted genes in an Antarctic dinoflagellate that steals chloroplasts from the haptophyte, Phaeocystis. Our project seeks to determine whether the kleptoplastidic dinoflagellate utilizes ancestral plastid proteins to regulate its stolen plastid, and how their transcription is related to environmental factors that are relevant to the Southern Ocean environment (temperature and light). To accomplish our goals, we have utilized high throughput transciptome analysis and RNA-Seq experiments of the dinoflagellate and Phaeocystis. Analysis of the dinoflagellate transcriptome has revealed complete mevalonic acid-independent and heme plastid-associated pathways as well as petF and petH transcripts with peridinin-plastid targeting sequences. In contrast, the proteins psaE, petJ, petC show similarity to non-Phaeocystis haptophyte homologs in their respective trees, and potentially carry haptophyte transit peptides. Anaylsis of RNA-Seq temperature and light experiments for the dinoflagellate indicate that there are significant differences in gene expression under the different environmental conditions, and we are in the process of identifying the genes associated with these changes. This work will help us to understand the environmental success of this alternative nutritional strategy.

Time Series Analysis for Spatial Node Selection in Environment Monitoring Sensor Networks

Bhandari, Siddhartha; Jurdak, Raja; Kusy, Branislav

2017-01-01

Wireless sensor networks are widely used in environmental monitoring. The number of sensor nodes to be deployed will vary depending on the desired spatio-temporal resolution. Selecting an optimal number, position and sampling rate for an array of sensor nodes in environmental monitoring is a challenging question. Most of the current solutions are either theoretical or simulation-based where the problems are tackled using random field theory, computational geometry or computer simulations, limiting their specificity to a given sensor deployment. Using an empirical dataset from a mine rehabilitation monitoring sensor network, this work proposes a data-driven approach where co-integrated time series analysis is used to select the number of sensors from a short-term deployment of a larger set of potential node positions. Analyses conducted on temperature time series show 75% of sensors are co-integrated. Using only 25% of the original nodes can generate a complete dataset within a 0.5 °C average error bound. Our data-driven approach to sensor position selection is applicable for spatiotemporal monitoring of spatially correlated environmental parameters to minimize deployment cost without compromising data resolution.

The Scientific Computing System (SCS) Data Assembly Center (DAC) was established in 2014 by the Office of Marine and Aviation Operations (OMAO) to evaluate the quality of full-resolution (sampling on the order of once per second) data collected by SCS onboard NOAA-operated research vessels. The SCS data are nominally transferred from the vessel to the National Centers for Environmental Information (NCEI) soon after the completion of each cruise and are complimented with detailed cruise metadata from OMAO. The authors will describe tools developed by the SCS DAC to monitor the timeliness of SCS data delivery to NCEI and the completeness of the SCS packages received by NCEI (ensuring the package contains data for all enabled sensors on a given cruise). Feedback to OMAO and NCEI regarding the timeliness and data completeness will be outlined along with challenges encountered by the DAC as it works to develop automated quality assessment of the SCS data packages.Data collected by SCS on NOAA vessels represent a significant investment by the American taxpayer. The mission of the SCS DAC is to ensure that archived SCS data at NCEI are a complete record of the observations made on NOAA research cruises. Archival of complete SCS datasets at NCEI ensures these data are preserved for future generations of scientists, policy makers, and the public.

2004-11-17

This work contributes to the design of safe and economical Generation-IV Super-Critical Water Reactors (SCWRs) by providing a basis for selecting structural materials to ensure the functionality of in-vessel components during the entire service life. During the second year of the project, we completed electrochemical characterization of the oxide film properties and investigation of crack initiation and propagation for candidate structural materials steels under supercritical conditions. We ranked candidate alloys against their susceptibility to environmentally assisted degradation based on the in situ data measure with an SRI-designed controlled distance electrochemistry (CDE) arrangement. A correlation between measurable oxide film properties andmore » susceptibility of austenitic steels to environmentally assisted degradation was observed experimentally. One of the major practical results of the present work is the experimentally proven ability of the economical CDE technique to supply in situ data for ranking candidate structural materials for Generation-IV SCRs. A potential use of the CDE arrangement developed ar SRI for building in situ sensors monitoring water chemistry in the heat transport circuit of Generation-IV SCWRs was evaluated and proved to be feasible.« less

The purpose of the study was to perform a comparative analysis of the technical performance, respective costs and environmental effect of two invasive analytical methods (HPLC and UV/visible-FTIR) as compared to a new non-invasive analytical technique (Raman spectroscopy). Three pharmacotherapeutic models were used to compare the analytical performances of the three analytical techniques. Statistical inter-method correlation analysis was performed using non-parametric correlation rank tests. The study's economic component combined calculations relative to the depreciation of the equipment and the estimated cost of an AQC unit of work. In any case, analytical validation parameters of the three techniques were satisfactory, and strong correlations between the two spectroscopic techniques vs. HPLC were found. In addition, Raman spectroscopy was found to be superior as compared to the other techniques for numerous key criteria including a complete safety for operators and their occupational environment, a non-invasive procedure, no need for consumables, and a low operating cost. Finally, Raman spectroscopy appears superior for technical, economic and environmental objectives, as compared with the other invasive analytical methods. Copyright © 2014 Elsevier B.V.

2013-04-01

In recent decades the institutions responsible for land management and civil protection have showed a great interest in relation to the use of more environmentally friendly techniques to mitigate the risk of landslides and floods. Soil bioengineering has responded to this need and several research groups are carrying out experimentations using the techniques of this discipline in the countries in the developing world. The Deistaf from University of Florence has concentrated its activities in this area over the past decade promoting the use of the techniques of Soil bioengineering in Latin America through the implementation of training and experimentation programmes. Numerous works have been completed both in riverbanks and on slopes in Nicaragua, Guatemala, Ecuador and Colombia. It was decided to make a census of interventions in Latin America from different institutions that may be related to Soil bioengineering in order to obtain an overview of the state of the art in the specific context taking into account also environmental and socio-economic issues. Taking advantage of its network of contacts, DEISTAF has collected dozens of sheets that describe interventions. These sheets describe, among other fields focused on the environment in which the work has been carried out, the materials and techniques used, and the impact of the intervention. In the sheets we present also the monitoring that has been realized for some of these works in the months of October and November 2012; we include the identification of the current condition and functionality of the intervention and, in the case of the presence of some damages, the formulation of instructions to fix them as well as the economic quantification of the repairs to be carried out.

The project undertaken by the Salix Consortium is a multi-phased, multi-partner endeavor. Phase-1 focused on initial development and testing of the technology and agreements necessary to demonstrate commercial willow production in Phase-2. The Phase-1 objectives have been successfully completed: preparing final design plans for two utility pulverized coal boilers, developing fuel supply plans for the project, obtaining power production commitments from the power companies for Phase-2, obtaining construction and environmental permits, and developing an experimental strategy for crop production and power generation improvements needed to assure commercial success. The R and D effort also addresses environmental issues pertaining to introductionmore » of the willow energy system. Beyond those Phase-1 requirements the Consortium has already successfully demonstrated cofiring at Greenidge Station and developed the required nursery capacity for acreage scale-up. This past summer 105 acres were prepared in advance for the spring planting in 1998. Having completed the above tasks, the Consortium is well positioned to begin Phase-2. In phase-2 every aspect of willow production and power generation from willow will be demonstrated. The ultimate objective of Phase-2 is to transition the work performed under the Rural Energy for the Future project into a thriving, self-supported energy crop enterprise.« less

Self-efficacy in Environmental Education: Experiences of elementary education preservice teachers

NASA Astrophysics Data System (ADS)

Gardner, Cynthia Crompton

Despite research showing Environmental Education can provide positive student outcomes in academic achievement, critical thinking, motivation and engagement (Ernst, 2007; Lieberman & Hoody, 1998; Orr, 1992; Palmer, 1998; Powers, 2004; Volk & Cheak, 2003), Environmental Education is currently not a critical element in American public school K-12 education. The present study investigates self-efficacy in Environmental Education through a mixed methods research approach. The data reveal the participants' perspectives of their sense of self-efficacy in Environmental Education. It adds to the body of work on Environmental Education and self-efficacy by specifically investigating the topics through interviews with preservice teachers. Purposeful sampling is used to identify preservice elementary education teachers in their senior year of college with a high measure of self-efficacy. Self-efficacy is measured using the Environmental Education Efficacy Belief Instrument (Sia, 1992). Forty-six preservice teachers completed the instrument. Six preservice teachers were interviewed to determine experiences that impact their self-efficacy in Environmental Education. Continual comparison and cross-case analysis are used to analyze the data. The results reveal a relationship between personal experiences with nature as a young child and current beliefs toward their personal efficacy and teaching outcome efficacy in Environmental Education. Similar to the findings of Sia (1992), the researcher discovered that preservice teachers realize that they lack sufficient knowledge and skill in Environmental Education but believe that effective teaching can increase students understanding of Environmental Education. While the preservice teachers do not believe they will teach Environmental Education as well as other subjects, they will continually seek out better ways to teach Environmental Education. Interviews with participants who had a high self-efficacy revealed the importance of playing outdoors as young children and having an adult role model with whom to share nature. Results showed that experiences with nature are absent in formal schooling, including courses in teacher education programs.

Complete energetic description of hydrokinetic turbine impact on flow channel dynamics

NASA Astrophysics Data System (ADS)

Brasseale, E.; Kawase, M.

2016-02-01

Energy budget analysis on tidal channels quantifies and demarcates the impacts of marine renewables on environmental fluid dynamics. Energy budget analysis assumes the change in total kinetic energy within a volume of fluid can be described by the work done by each force acting on the flow. In a numerically simulated channel, the balance between energy change and work done has been validated up to 5% error.The forces doing work on the flow include pressure, turbulent dissipation, and stress from the estuary floor. If hydrokinetic turbines are installed in an estuarine channel to convert tidal energy into usable power, the dynamics of the channel change. Turbines provide additional pressure work against the flow of the channel which will slow the current and lessen turbulent dissipation and bottom stress. These losses may negatively impact estuarine circulation, seafloor scour, and stratification.The environmental effects of turbine deployment have been quantified using a three dimensional, Reynolds-averaged, Navier-Stokes model of an idealized flow channel situated between the ocean and a large estuarine basin. The channel is five kilometers wide, twenty kilometers long and fifty meters deep, and resolved to a grid size of 10 meters by 10 meters by 1 meter. Tidal currents are simulated by an initial difference in sea surface height across the channel of 160 centimeters from the channel entrance to the channel exit. This creates a pressure gradient which drives flow through the channel. Tidal power turbines are represented as disks that force the channel in proportion to the strength of the current. Three tidal turbines twenty meters in diameters have been included in the model to simulate the impacts of a pilot scale test deployment.This study is the first to appreciate the energetic impact of marine renewables in a three dimensional model through the energy equation's constituent terms. This study provides groundwork for understanding and predicting the environmental impacts of marine renewables.

Web Application for Coastal Area Planning through Analysis of Landslide and Soil Consumption

Global warming and rapid climatic changes are producing dramatic effects on coastal area of Mediterranean countries. Italian coastal areas are one of the most urbanized zones of the south western Europe and the extensive use of soil is causing a consistent impact on the hydrogeological context. Moreover, soil consumption combined with extreme meteorological events, facilitates the occurrence of hazardous landslide events. Environmental policy makers and data managers in territorial planning need to face such emergency situation with appropriate tools. We present an application service with the aim of advising user through environmental analysis of Landslide and Soil Consumption impact. This service wants also to improve the sharing of environmental harmonized datasets/metadata across different organizations and the creation of a collaborative environment where the stakeholders and environmental experts can share their data and work cooperatively. We developed a set of processing services providing functionalities to assess impact of landslide on territory and impact of land take and soil sealing. Among others, the service is able to evaluate environmental impacts of landslide events on Cultural Heritage sites. We have also designed a 3D WebGL client customized to execute the processing services and visualize their outputs. It provides high usability in terms of navigation and data visualization. In this way the service provides not only a Spatial Data Infrastructure to access and visualize data but a complete Decision Support Systems for a more effective environmental planning of coastal area.

Etiological contributions to the covariation between children's perceptions of inter-parental conflict and child behavioral problems.

Nikolas, Molly; Klump, Kelly L; Burt, S Alexandra

2013-02-01

Prior work has suggested that inter-parental conflict likely plays an etiological role in child behavior problems. However, family-level measurement of inter-parental conflict in most traditional child twin studies has made it difficult to tease apart the specific causal mechanisms underlying this association. The Children's Perception of Inter-parental Conflict scale (CPIC) provides a child-specific measurement tool for examining these questions, as its subscales tap multiple dimensions of conflict assessed from the child's (rather than the parent's) perspective. The current study examined (1) the degree of genetic and environmental influence on each of the CPIC subscales, and (2) etiological contributions to the covariation between the CPIC scales and parental reports of child behavioral problems. The CPIC was completed by 1,200 child twins (aged 6-11 years) from the Michigan State University Twin Registry (MSUTR). Parents completed the Child Behavior Checklist (CBCL) to assess child internalizing and externalizing behavior problems. Multivariate models were examined to evaluate the relative contributions of genetic and environmental factors to both the CPIC scales and to their overlap with child behavioral outcomes. Modeling results indicated no significant moderation of sex or age. Significant environmental overlap emerged between the CPIC conflict properties scale and child internalizing and externalizing problems. By contrast, significant genetic correlations emerged between the CPIC self-blame scale and externalizing problems as well as between the CPIC threat scale and internalizing problems. Overall, findings suggest that the subscales of the CPIC are somewhat etiologically diverse and may provide a useful tool for future investigations of possible gene-environment interplay.

The Importance of Field Demonstration Sites: The View from the Unconventional Resource Region of the Appalachian Basin

NASA Astrophysics Data System (ADS)

Carr, T.

2017-12-01

The Appalachian basin with the Marcellus and Utica shale units is one of the most active unconventional resource plays in North America. Unconventional resource plays are critical and rapidly-growing areas of energy, where research lags behind exploration and production activity. There remains a poor overall understanding of physical, chemical and biological factors that control shale gas production efficiency and possible environmental impacts associated with shale gas development. We have developed an approach that works with local industrial partners and communities and across research organizations. The Marcellus Shale Energy and Environment Laboratory (MSEEL) consists of a multidisciplinary and multi-institutional team undertaking integrated geoscience, engineering and environmental studies in cooperation with the Department of Energy. This approach is being expanded to other sites and to the international arena. MSEEL consists of four horizontal production wells, which are instrumented, a cored and logged vertical pilot bore-hole, and a microseismic observation well. MSEEL has integrated geophysical observations (microseismic and surface), fiber-optic monitoring for distributed acoustic (DAS) and temperature sensing (DTS), well logs, core data and production logging and continued monitoring, to characterize subsurface rock properties, and the propagation pattern of induced fractures in the stimulated reservoir volume. Significant geologic heterogeneity along the lateral affects fracture stimulation efficiency - both completion efficiency (clusters that receive effective stimulation), and production efficiency (clusters effectively contributing to production). MSEEL works to develop new knowledge of subsurface geology and engineering, and surface environmental impact to identify best practices that can optimize hydraulic fracture stimulation to increase flow rates, estimated ultimate recovery in order to reduce the number of wells and environmental impact.

Advanced manufacturing development of a composite empennage component for L-1011 aircraft

Work on process verification and tooling development continued. The cover process development was completed with the decision to proceed with low resin content prepreg material (34 + or - 3% by weight) in the fabrication of production readiness verification test (PRVT) specimens and the full-scale covers. The structural integrity of the cover/joint design was verified with the successful test of the cover attachment to fuselage ancillary test specimen (H25). Failure occurred, as predicted, in the skin panel away from the fuselage joint at 141 percent of the design ultimate load. With the successful completion of the H25 test, the PRVT cover specimens, which are identical to the H25 ancillary test specimen, were cleared for production. Eight of the twenty cover specimens were fabricated and are in preparation for test. All twenty of the PRVT spar specimens were fabricated and also were prepared for test. The environmental chambers used in the durability test of ten cover and ten spar PRVT specimens were completed and installed in the load reaction frames.

Distinguishing Error from Chaos in Ecological Time Series

1990-11-01

Over the years, there has been much discussion about the relative importance of environmental and biological factors in regulating natural populations. Often it is thought that environmental factors are associated with stochastic fluctuations in population density, and biological ones with deterministic regulation. We revisit these ideas in the light of recent work on chaos and nonlinear systems. We show that completely deterministic regulatory factors can lead to apparently random fluctuations in population density, and we then develop a new method (that can be applied to limited data sets) to make practical distinctions between apparently noisy dynamics produced by low-dimensional chaos and population variation that in fact derives from random (high-dimensional)noise, such as environmental stochasticity or sampling error. To show its practical use, the method is first applied to models where the dynamics are known. We then apply the method to several sets of real data, including newly analysed data on the incidence of measles in the United Kingdom. Here the additional problems of secular trends and spatial effects are explored. In particular, we find that on a city-by-city scale measles exhibits low-dimensional chaos (as has previously been found for measles in New York City), whereas on a larger, country-wide scale the dynamics appear as a noisy two-year cycle. In addition to shedding light on the basic dynamics of some nonlinear biological systems, this work dramatizes how the scale on which data is collected and analysed can affect the conclusions drawn.

Whale baleen trace element signatures: a predictor of environmental life history?

The analysis of trace element composition of biogenic structures (e.g., otoliths, feathers) by laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) provides unique insights into the environmental life history of individuals. We studied the trace element chemistry of right whale baleens in an attempt to reconstruct migration patterns. Though much is known about the feeding and breeding habitats of these whales, little is known about the location in which they spend most of their adult years. Baleens, made of keratin, grow continuously and are metabolically inactive. Previous work showed that the stable isotope chemistry along the length of a baleen records changes in diet, such as weaning. Baleen chemistry should, therefore, also record the environmental life history of the individual. Trace metal chemistry along a single baleen plate from a right whale were analyzed by LA-ICP-MS. Semi-quantitative elemental signatures were obtained using NIST 612 (glass standard) and MACS-3 (calcium carbonate standard). These concentrations were then compared for accuracy to acid digested baleen laterally adjacent to the laser ablation site via aqueous ICP-MS. Elemental chemistry was compared to known feeding/breeding locations of the individual (water chemistry). Using these comparisons as well as principal components analysis, life history of the individual was reconstructed. Development of an in-house keratin standard is in progress and is expected to strengthen the confidence in results. Future work is expected to bring a more complete knowledge of right whale wintering habits.

Iowa has the highest average radon concentrations in the nation, with an estimated 400 radon-induced lung cancer deaths each year. Radon is the second leading cause of lung cancer death overall. The objectives of this study were (1) to educate the population attending a family medicine office about the dangers of radon, (2) to encourage homeowners to test for radon, (3) to work with the community to identify resources for mitigation, and (4) to assess the utility of working with a local family medicine office as a model that could be adopted for other communities with high home radon concentrations. Participants obtained a US Environmental Protection Agency-certified activated charcoal short-term radon kit through their primary care office or by attending a seminar held by their medical office. Participants completed a short investigator-developed questionnaire about their home, heating, and demographics. Of 746 radon kits handed out, 378 valid results (51%) were received, of which 351 questionnaires could be matched to the kit results. The mean radon result was 10.0 pCi/L (standard deviation, 8.5 pCi/L). A radon result of 4 pCi/L or higher, the Environmental Protection Agency action level for mitigation, was found in 81% of homes (n = 285). Four of 5 homes tested had elevated radon levels. This family medicine office/university collaborative educational model could be useful for educating patients about other environmental dangers. © Copyright 2015 by the American Board of Family Medicine.

Spatio-temporal analysis of preterm birth in Portugal and its relation with environmental variables

Preterm birth (PTB), one of the major concerns in obstetrics, is conventionally defined as the delivery of a live infant before 37 completed weeks of gestation, and one of its causes may be environmental factors. Remote sensing is a valuable approach for monitoring environmental variables, including in health sciences. In this work, remote sensing data were used to explore the relation of the environment with PTB. Time-series with monthly rates of male/female ratio and PTB were obtained from Portugal in 2000-2014. The environmental variables included in this study were monthly mean temperatures (T), relative humidity (RH), NDVI, concentrations of NO2 and PM10 in 2003-2008. A temporal and spatial analysis of each health-related and environmental variable was performed, as well as their correlation. PTB has been increasing over time, from below 5% in 2000 to around 7% in 2014, with predominance of higher rates in districts with larger population. From 2003 to 2008, T and PM10 decreased significantly. A positive and significant correlation was found between male/female ratio and NO2 and RH, and to a lesser extent with PM10 and NDVI. PTB was also positively and significantly correlated with NO2 and T, and to a lesser extent with RH and PM10. These preliminary results suggest an association of PTB with most of the environmental variables studied, showing that more polluted and populated districts have higher rates of PTB. Further studies are warranted to explore interaction between the considered environmental factors and other variables related with risk for PTB.

Phytoremediation of landfill leachate.

PubMed

Jones, D L; Williamson, K L; Owen, A G

2006-01-01

Leachate emissions from landfill sites are of concern, primarily due to their toxic impact when released unchecked into the environment, and the potential for landfill sites to generate leachate for many hundreds of years following closure. Consequently, economically and environmentally sustainable disposal options are a priority in waste management. One potential option is the use of soil-plant based remediation schemes. In many cases, using either trees (including short rotation coppice) or grassland, phytoremediation of leachate has been successful. However, there are a significant number of examples where phytoremediation has failed. Typically, this failure can be ascribed to excessive leachate application and poor management due to a fundamental lack of understanding of the plant-soil system. On balance, with careful management, phytoremediation can be viewed as a sustainable, cost effective and environmentally sound option which is capable of treating 250m(3)ha(-1)yr(-1). However, these schemes have a requirement for large land areas and must be capable of responding to changes in leachate quality and quantity, problems of scheme establishment and maintenance, continual environmental monitoring and seasonal patterns of plant growth. Although the fundamental underpinning science is well understood, further work is required to create long-term predictive remediation models, full environmental impact assessments, a complete life-cycle analysis and economic analyses for a wide range of landfill scenarios.

Transition and closeout of the Fernald Closure Project

Bilson, H.E.; Terry, T.; Reising, J.

The U.S. Department of Energy (DOE) and Fluor Fernald have completed the majority of the cleanup of the Fernald Site. The over 1,000 acre complex for processing uranium has been demolished and soil contamination has been remediated. With acres of wetlands and prairies replacing the buildings and waste pits. At the end of the project the focus shifted to developing demonstrating the completion of the project and the contract, as well as ensuring a smooth transition of the facility from the DOE's Environmental Management (EM) Program to the DOE's Legacy Management (LM) Program. Working with the DOE, each portion ofmore » the closure contract was examined for specific closure definition. From this negotiation effort the Comprehensive Exit and Transition Plan (CE/T Plan) was written. The CE/T Plan is intended to assist DOE in the analysis that the site is ready for transfer into long-term stewardship (LTS) (also referred to as legacy management) and that Fluor Fernald, Inc. has satisfactorily completed the closure contract statement of work elements. Following the Lessons Learned from the closure of the Rocky Flats Site, the DOE's Legacy Management Program created a matrix of Transition Elements required to ensure adequate information was in place to allow the new prime contractor to perform the Legacy Management scope of work. The transition plan included over 1,000 elements broken down into functional areas and relied on specific Fernald Responsibility Transition Packages (RTPs) for detailed transition actions. The template for Closure and Transition Planning used at the Fernald Site was developed using the best Lessons Learned from across the DOE Complex. The template could be used for other sites, and lessons learned from this closure and transition will be appropriate for all closure projects. (authors)« less

To investigate the effectiveness of a combined social and physical environmental intervention as well as the effectiveness of both separate interventions. In a 2 × 2 factorial design, 412 office employees were allocated to the combined social and physical environmental intervention, to the social environmental intervention only, to the physical environmental intervention only, or were part of the control group. Data on presenteeism, absenteeism, work performance, and work engagement were obtained with questionnaires at baseline, 6, and 12 months. Multilevel analyses were performed. The combined intervention showed a decrease in contextual performance and dedication. The social environmental intervention showed an improvement in task performance. The physical environmental intervention revealed an improvement in absorption. Although the study showed some promising results, it is not recommended to implement the current interventions.

Predicting the Influence of Situational and Immigration Stress on Latino Day Laborers' Workplace Injuries: An Exploratory Structural Equation Model.

Fernández-Esquer, Maria Eugenia; Gallardo, Kathryn R; Diamond, Pamela M

2018-05-16

Latino day laborers are a socially and economically marginalized immigrant population with a high risk of occupational injury. These workers confront multiple social, psychological, and environmental hardships that increase their risk for adverse health outcomes. How these stressors interact and influence work-related injuries in this population remains unclear. We conducted an exploratory study with 327 Latino day laborers who completed a community survey. We developed a structural equation model, using cross-sectional data to explore the relationships among socioeconomic status, situational and immigration stress, depression, work risk exposure, and occupational injury. The model revealed a statistically significant mediated effect from situational stress to injury through work risk exposure as well as a significant mediated effect from immigration stress through depression to injury. These initial findings suggest that situational and immigration-related stress have a detrimental impact on Latino day laborers' mental health and workplace safety and, ultimately, increase their risk of occupational injury.

In 2006 the Laboratory reduced its generator status from a Large Quantity Generator (LQG) to a Smallmore » Quantity Generator (SQG). EPA Region VII was notified of this change. The Laboratory's RCRA hazardous waste management program was inspected by EPA Region VII in April 2006. There were no notices of violations. The inspector was impressed with the improvements of the Laboratory's waste management program over the past ten years. The Laboratory was in compliance with all applicable federal, state, local and DOE regulations and orders in 2010. There were no radiological air emissions or exposures to the general public due to Laboratory activities in 2010. See U.S. Department of Energy Air Emissions Annual Report in Appendix B. As indicated in prior SERs, pollution awareness, waste minimization and recycling programs have been in practice since 1990, with improvements implemented most recently in 2010. Included in these efforts were battery and CRT recycling, miscellaneous electronic office equipment, waste white paper and green computer paper-recycling and corrugated cardboard recycling. Ames Laboratory also recycles/reuses salvageable metal, used oil, foamed polystyrene peanuts, batteries, fluorescent lamps and telephone books. Ames Laboratory reported to DOE-Ames Site Office (AMSO), through the Laboratory's Performance Evaluation Measurement Plan, on its Affirmative Procurement Performance Measure. A performance level of 'A-' was achieved in 2010 for Integrated Safety, Health and Environmental Protection. As reported in Site Environmental Reports for prior years, the Laboratory's Environmental Management System (EMS) has been integrated into the Laboratory's Integrated Safety Management System since 2005. The integration of EMS into the way the Laboratory does business allows the Laboratory to systematically review, address and respond to the Laboratory's environmental impacts. The Laboratory's EMS was audited in April 2009 by DOE-CH. There were four 'Sufficiently in Conformity' findings as a result of the audit. All four findings were tracked in the Laboratory's corrective action database for completion. Beryllium was used routinely at Ames Laboratory in the 1940's and 1950's in processes developed for the production of highly pure uranium and thorium in support of the historic Manhattan Project. Laboratory metallurgists also worked on a process to produce pure beryllium metal from beryllium fluoride. In the early 1950's, beryllium oxide powder was used to produce shaped beryllium and crucibles. As a result of that work, beryllium contamination now exists in many interstitial spaces (e.g., utility chases) and ventilation systems in Wilhelm, Spedding and Metals Development buildings. Extensive characterization and remediation efforts have occurred in 2009 and 2010 in order to better understand the extent of the contamination. Analysis of extensive sampling data suggests that a fairly wide dispersion of beryllium occurred (most likely in the 1950's and 60's) in Wilhelm Hall and in certain areas of Spedding Hall and Metals Development. Area air-sampling results and work-area surface characterizations indicate the exposure potential to current workers, building visitors and the public remains extremely low. This information is now used to guide cleaning efforts and to provide worker protection during remodeling and maintenance activities. Results were shared with the DOE's Former Worker Program to support former worker medical testing and compensation programs.

Using Service-Learning Projects to Jump Start Research at Small Institutions

Ongley, L. K.; Spigel, K.; Olin, J.

2010-12-01

Geoscientists at small institutions must frequently be very creative about funding and conducting research. High teaching loads, tuition-driven budgets, and a dearth of geosciences colleagues all contribute challenges to an intellectual life that includes research as a scholarship endeavor. Fortunately, service-learning can be used as a multi-purpose pedagogical technique. Unity College is a very small environmentally-focused undergraduate institution in rural Maine with a student population of less than 600 students. Our students really appreciate learning in the field and through participation in projects that impact the communities in which they live and study. Our Environmental Science (geosciences) and Environmental Analysis (chemistry) majors have been showing increasing interest in pursuing graduate school and independent projects in greater and greater depth. In the past 5 years we have had a complete turn-over in geoscience and chemistry faculty (2 persons), a shift that has brought new ideas to campus and a different idea about importance of research. Unity College has always been a big proponent of community-based projects so the extension to service learning as a pedagogical technique has been smooth. A wide variety of towns, schools, land trusts, pond associations and other groups approach Unity College with project ideas. We are best equipped to handle suggestions that relate to environmental chemistry and to lake sedimentation owing to the research interests of our geoscience faculty. We present two examples of ways to sequence student work that ultimately end in student/faculty research projects. Sophomores in the Unity College Environmental Stewardship Core curriculum may choose to take a course that introduces lake sedimentation as a tool to study environmental change. Students in the course take several sediment cores to analyze proxies of environmental change to reconstruct past environments. The final results are reported to the community client. Other sediment cores are preserved for upper-level students to use as detailed independent studies or senior thesis projects. In time, there will be enough data from enough lakes in the area to build a detailed picture of environmental change in this region of Maine and to predict expected impacts of climate change. The community clients for project of this type include Friends of Lake Winnecook and the Sebasticook Regional Land Trust. Over the past four years Environmental Analysis students have been working on arsenic in drinking water systems. Students have performed literature reviews, evaluated field techniques for analysis of arsenic in water and looked for diurnal variation in arsenic concentrations in a domestic water well. Next spring, one general chemistry lab section will set up and run “Arsenic Days”, a community event to which residents may bring a water sample for analysis of arsenic and other water quality parameters. This will provide a large dataset to assess the overall water quality in the three aquifers present in Unity, Maine. Some of this work is applicable to global water quality problems. The “clients” for this work include Chemists Without Borders and the Unity Barnraisers. In each case, the results of the research have been reported at various professional meetings as well as to the “client”.

The Base Environmental Management System (BEMS) is a Web-based application program for managing and tracking audits by the Environmental Office of Stennis Space Center in conformity with standard 14001 of the International Organization for Standardization (ISO 14001). (This standard specifies requirements for an environmental-management system.) BEMS saves time by partly automating what were previously manual processes for creating audit checklists; recording and tracking audit results; issuing, tracking, and implementing corrective-action requests (CARs); tracking continuous improvements (CIs); and tracking audit results and statistics. BEMS consists of an administration module and an auditor module. As its name suggests, the administration module is used to administer the audit. It helps administrators to edit the list of audit questions; edit the list of audit locations; assign mandatory questions to locations; track, approve, and edit CARs; and edit completed audits. The auditor module is used by auditors to perform audits and record audit results: it helps the auditors to create audit checklists, complete audits, view completed audits, create CARs, record and acknowledge CIs, and generate reports from audit results.

In recent years, new strict environmental laws have required improved and cost-effective water purification methods by Air Force complexes. Naturally assisted primary units (microbiological) and secondary units (macrophyte) could bring waste treatment systems into tighter compliance. Aquatic macrophytes which have rapid growth rates and absorb large quantities of nutrients could provide a practical and economic method for more complete wastewater maintenance, hazardous waste clean-up or river, lake and ground water purification. This work has shown that Lemna minor, or Common Duckweed, can successfully and thoroughly accumulate organics and metals from Air Force wastewaters.

Mapping the environmental and biogeographic complexity of the Amazon basin using remote sensing methods

NASA Astrophysics Data System (ADS)

Streher, A. S.; Cordeiro, C. L. O.; Silva, T. S. F.

2017-12-01

Mapping environmental envelopes onto geographical space has been classically important for understanding biogeographical patterns. Knowing the biotic and abiotic limits defining these envelopes, we can better understand the requirements limiting species distributions. Most present efforts in this regard have focused on single-species distribution models, but the current breadth and accessibility of quantitative, spatially explicit environmental information can also be explored from an environment-first perspective. We thus used remote sensing to determine the occurrence of environmental discontinuities in the Amazon region and evaluated if such discontinuities may act as barriers to determine species distribution and range limits, forming clear environmental envelopes. We combined data on topography (SRTM), precipitation (CHIRPS), vegetation descriptors (PALSAR-1 backscattering, biomass, NDVI) and temperature (MODIS), using object-based image analysis and unsupervised learning to map environmental envelopes. We identified 14 environmental envelopes for the Amazon sensu latissimo region, mainly delimited by changes in vegetation, topography and precipitation. The resulting envelopes were compared to the distribution of 120 species of Trogonidae, Galbulidae, Bucconidae, Cebidae, Hylidae and Lecythidaceae, amounting to 22,649 occurrence records within the Amazonregion. We determined species prevalence in each envelope by calculating the ratio between species relative frequency per envelope and envelope relative frequency (area) in the complete map. Values closer to 1 indicate a high degree of prevalence. We found strong envelope associations (prevalence > 0.5) for 20 species (17% of analyzed taxa). Although several biogeographical and ecological factors will influence the distribution of a species, our results show that not only geographical barriers, but also modern environmental discontinuities may limit the distribution of some species., and may have also done so in the past. Our work also highlights the environmental complexity of the Amazon region, often considered as "environmentally homogeneous", and shows how environmental mapping can contribute to better understanding of the processes explaining the current assembly and distribution of Amazon biodiversity.

2013-12-01

This is the first study to explore genetic and environmental contributions to individual differences in emotion regulation in toddlers, and the first to examine the genetic and environmental etiology underlying the association between emotion regulation and working memory. In a sample of 304 same-sex twin pairs (140 MZ, 164 DZ) at age 3, emotion regulation was assessed using the Behavior Rating Scale of the Bayley Scales of Infant Development (BRS; Bayley, 1993), and working memory was measured by the visually cued recall (VCR) task (Zelazo, Jacques, Burack, & Frye, 2002) and several memory tasks from the Mental Scale of the BSID. Based on model-fitting analyses, both emotion regulation and working memory were significantly influenced by genetic and nonshared environmental factors. Shared environmental effects were significant for working memory, but not for emotion regulation. Only genetic factors significantly contributed to the covariation between emotion regulation and working memory.

Granger Morgan, M.

2011-04-01

In a book for the general public published a year before his death, Carl Sagan wrote, "Every time a scientific paper presents a bit of data, it's accompanied by an error bar---a quiet but instant reminder that no knowledge is complete or perfect." For those of us educated in experimental natural science such an observation seems so obvious as to hardly need saying. Yet when, after completing a PhD in experimental radio physics, I began to work on problems in environmental and energy risk and policy analysis in the early 1970s, I was amazed to find that the characterization and treatment of uncertainty was almost completely lacking in the analysis of that day. In the first part of this talk, I will briefly summarize how I, and a number of my physics-educated colleagues, have worked to rectify this situation. Doctoral education in the Department of Engineering and Public Policy (EPP) at Carnegie Mellon University has also been shaped by a number of ideas and problem-solving styles that derive from physics. These have been strengthened considerably through integration with a number of ideas from experimental social science -- a field that too many in physics ignore or even belittle. In the second part of the talk, I will describe the PhD program in EPP, talk a bit about some of its unique features, and describe a few of the problems we address.

Development of a probabilistic PCB-bioaccumulation model for six fish species in the Hudson River

In 1984 the US Environmental Protection Agency (USEPA) completed a Feasibility Study on the Hudson River that investigated remedial alternatives and issued a Record of Decision (ROD) later that year. In December 1989 USEPA decided to reassess the No Action decision for Hudson River sediments. This reassessment consists of three phases: Interim Characterization and Evaluation (Phase 1); Further Site Characterization and Analysis (Phase 2); and, Feasibility study (Phase 3). A Phase 1 report was completed in August, 1991. The team then completed a Final Work Plan for Phase 2 in September 1992. This work plan identified various PCB fate andmore » transport modeling activities to support the Hudson River PCB Reassessment Remedial Investigation and Feasibility Study (RI/FS). This talk provides a description of the development of a Probabilistic bioaccumulation models to describe the uptake of PCBs on a congener-specific basis in six fish species. The authors have developed a framework for relating body burdens of PCBs in fish to exposure concentrations in Hudson River water and sediments. This framework is used to understand historical and current relationships as well as to predict fish body burdens for future conditions under specific remediation and no action scenarios. The framework incorporates a probabilistic approach to predict distributions in PCB body burdens for selected fish species. These models can predict single population statistics such as the average expected values of PCBs under specific scenarios as well as the distribution of expected concentrations.« less

The Coal Ash Resources Research Consortium{reg_sign} (CARRC{reg_sign}, pronounced 'cars') is the core coal combustion product (CCP) research group at the Energy & Environmental Research Center (EERC). CARRC focuses on performing fundamental and applied scientific and engineering research emphasizing the environmentally safe, economical use of CCPs. CARRC member organizations, which include utilities and marketers, are key to developing industry-driven research in the area of CCP utilization and ensuring its successful application. The U.S. Department of Energy is a partner in CARRC through the EERC Jointly Sponsored Research Program, which provides matching funds for industrial member contributions and facilitates an increased levelmore » of effort in CARRC. CARRC tasks were designed to provide information on CCP performance, including environmental performance, engineering performance, favorable economics, and improved life cycle of products and projects. CARRC technical research tasks are developed based on member input and prioritization. CARRC special projects are developed with members and nonmembers to provide similar information and to support activities, including the assembly and interpretation of data, support for standards development and technology transfer, and facilitating product development and testing. CARRC activities from 2007 to 2009 included a range of research tasks, with primary work performed in laboratory tasks developed to answer specific questions or evaluate important fundamental properties of CCPs. The tasks were included in four categories: (1) Environmental Evaluations of CCPs; (2) Evaluation of Impacts on CCPs from Emission Controls; (3) Construction and Product-Related Activities; and (4) Technology Transfer and Maintenance Tasks. All tasks are designed to work toward achieving the CARRC overall goal and supporting objectives. The various tasks are coordinated in order to provide broad and useful technical data for CARRC members. Special projects provide an opportunity for non-CARRC members to sponsor specific research or technology transfer consistent with CARRC goals. This report covers CARRC activities from January 2007 through March 2009. These activities have been reported in CARRC Annual Reports and in member meetings over the past 2 years. CARRC continues to work with industry and various government agencies with its research, development, demonstration, and promotional activities nearing completion at the time of submission of this report. CARRC expects to continue its service to the coal ash industry in 2009 and beyond to work toward the common goal of advancing coal ash utilization by solving CCP-related technical issues and promoting the environmentally safe, technically sound, and economically viable management of these complex and changing materials.« less

Designing at Scale: Lessons in Relevance, Quality, and Equity from ChangeScale, a Bay Area environmental education collaborative

2015-12-01

The best environmental education equips people with the know-how and drive to create healthy communities and a healthy planet. While there are many wonderful organizations providing environmental learning, ensuring quality, cultural relevance and equity of access remains an elusive goal--especially if environmental education organizations work in isolation. Organizations across 12 counties in the Bay Area have come together to create a different model. They have founded ChangeScale, a regional collaborative dedicated to providing high quality environmental education to hundreds of thousands of youth---by working together. ChangeScale's work involves setting up school district-level partnerships, providing technical assistance to local environmental education networks, and training environmental educators across the region. In this talk, the presenter, who is a founding member and steering committee chair for ChangeScale, will outline the challenges of working at a regional scale with dozens of organizations. She will share the processes ChangeScale has used to develop a business plan and build membership. She will conclude by sharing the short term and long term potential impacts of working collectively for environmental literacy in the Bay Area.

The research findings fill a gap in the body of knowledge by presenting an effective way to evaluate the significance of on-site environmental impacts of municipal engineering works prior to the construction stage. First, 42 on-site environmental impacts of municipal engineering works were identified by means of a process-oriented approach. Then, 46 indicators and their corresponding significance limits were determined on the basis of a statistical analysis of 25 new-build and remodelling municipal engineering projects. In order to ensure the objectivity of the assessment process, direct and indirect indicators were always based on quantitative data from the municipal engineering projectmore » documents. Finally, two case studies were analysed and found to illustrate the practical use of the proposed model. The model highlights the significant environmental impacts of a particular municipal engineering project prior to the construction stage. Consequently, preventive actions can be planned and implemented during on-site activities. The results of the model also allow a comparison of proposed municipal engineering projects and alternatives with respect to the overall on-site environmental impact and the absolute importance of a particular environmental aspect. These findings are useful within the framework of the environmental impact assessment process, as they help to improve the identification and evaluation of on-site environmental aspects of municipal engineering works. The findings may also be of use to construction companies that are willing to implement an environmental management system or simply wish to improve on-site environmental performance in municipal engineering projects. -- Highlights: • We present a model to predict the environmental impacts of municipal engineering works. • It highlights significant on-site environmental impacts prior to the construction stage. • Findings are useful within the environmental impact assessment process. • They also help contractors to implement environmental management systems.« less

Recovering incomplete data using Statistical Multiple Imputations (SMI): a case study in environmental chemistry.

PubMed

Mercer, Theresa G; Frostick, Lynne E; Walmsley, Anthony D

2011-10-15

This paper presents a statistical technique that can be applied to environmental chemistry data where missing values and limit of detection levels prevent the application of statistics. A working example is taken from an environmental leaching study that was set up to determine if there were significant differences in levels of leached arsenic (As), chromium (Cr) and copper (Cu) between lysimeters containing preservative treated wood waste and those containing untreated wood. Fourteen lysimeters were setup and left in natural conditions for 21 weeks. The resultant leachate was analysed by ICP-OES to determine the As, Cr and Cu concentrations. However, due to the variation inherent in each lysimeter combined with the limits of detection offered by ICP-OES, the collected quantitative data was somewhat incomplete. Initial data analysis was hampered by the number of 'missing values' in the data. To recover the dataset, the statistical tool of Statistical Multiple Imputation (SMI) was applied, and the data was re-analysed successfully. It was demonstrated that using SMI did not affect the variance in the data, but facilitated analysis of the complete dataset. Copyright © 2011 Elsevier B.V. All rights reserved.

Urban Field Experiences for Undergraduate Liberal Arts Students: Using Compromised Environments as Living Laboratories

NASA Astrophysics Data System (ADS)

MacAvoy, S. E.; Knee, K.

2015-12-01

While urban environments may lack the beauty of relatively pristine field sites, they can be used to deliver an effective demonstration of actual environmental damage. Students demanding applied field experiences from their undergraduate environmental science programs can be well served in urban settings. Here, we present strategies for integrating degraded urban systems into the undergraduate field experience. Urban locations provide an opportunity for a different type of local "field-work" than would otherwise be available. In the upper-level undergraduate Environmental Methods class, we relied on a National Park area located a 10-minute walk from campus for most field exercises. Activities included soil analysis, measuring stream flow and water quality parameters, dendrochronology, and aquatic microbe metabolism. In the non-majors class, we make use of our urban location to contrast water quality in parks and highly channelized urban streams. Students spend labs immersed in streams and wetlands heavily impacted by the urban runoff their city generates. Here we share lesson plans and budgets for field activities that can be completed during a class period of 2.5 hours with a $75 course fee, show how these activities help students gain quantitative competency.

Human Life History Strategies.

PubMed

Chua, Kristine J; Lukaszewski, Aaron W; Grant, DeMond M; Sng, Oliver

2017-01-01

Human life history (LH) strategies are theoretically regulated by developmental exposure to environmental cues that ancestrally predicted LH-relevant world states (e.g., risk of morbidity-mortality). Recent modeling work has raised the question of whether the association of childhood family factors with adult LH variation arises via (i) direct sampling of external environmental cues during development and/or (ii) calibration of LH strategies to internal somatic condition (i.e., health), which itself reflects exposure to variably favorable environments. The present research tested between these possibilities through three online surveys involving a total of over 26,000 participants. Participants completed questionnaires assessing components of self-reported environmental harshness (i.e., socioeconomic status, family neglect, and neighborhood crime), health status, and various LH-related psychological and behavioral phenotypes (e.g., mating strategies, paranoia, and anxiety), modeled as a unidimensional latent variable. Structural equation models suggested that exposure to harsh ecologies had direct effects on latent LH strategy as well as indirect effects on latent LH strategy mediated via health status. These findings suggest that human LH strategies may be calibrated to both external and internal cues and that such calibrational effects manifest in a wide range of psychological and behavioral phenotypes.

Putting performance in context: the perceived influence of environmental factors on work-based performance.

2015-10-01

Context shapes behaviours yet is seldom considered when assessing competence. Our objective was to explore attending physicians' and trainees' perceptions of the Internal Medicine Clinical Teaching Unit (CTU) environment and how they thought contextual factors affected their performance. 29 individuals recently completing CTU rotations participated in nine level-specific focus groups (2 with attending physicians, 3 with senior and 2 with junior residents, and 2 with students). Participants were asked to identify environmental factors on the CTU and to describe how these factors influenced their own performance across CanMEDS roles. Discussions were analyzed using constructivist grounded theory. Five major contextual factors were identified: Busyness, Multiple Hats, Other People, Educational Structures, and Hospital Resources and Policies. Busyness emerged as the most important, but all factors had a substantial perceived impact on performance. Participants felt their performance on the Manager and Scholar roles was most affected by environmental factors (mostly negatively, due to decreased efficiency and impact on learning). In complex workplace environments, numerous factors shape performance. These contextual factors and their impact need to be considered in observations and judgements made about performance in the workplace, as without this understanding conclusions about competency may be flawed.

Environmental noise is a worldwide problem that has an adverse effect in the quality of life of urban population. Some work has shown that there is a correlation between environmental noise and health issues as sleep disturbance or annoyance. This study presents the time evolution of a test track fabricated with an asphalt mixture with 20% of crumb rubber by weight of bitumen, added by the wet process. A complete surface characterization has been performed by determining tire/pavement sound levels, road texture profiles, in-situ dynamic stiffness and sound absorption of compacted and extracted sample cores. Two measurement campaigns were performed: just after mixture laying and after 3 years in service. This study confirms that the use of crumb rubber as a modifier of bituminous binders (CRMB) can improve the pavement characteristics: gap-graded mixtures with crumb rubber can be used in the action plans as urban rehabilitation measure to fight noise pollution. However, this noise reduction seems to decrease with age at a rate of approximately 0.15 dB(A) per year. Copyright © 2015 Elsevier B.V. All rights reserved.

A complete understanding of both the steady state and transient background measured by Radiation Portal Monitors (RPMs) is essential to predictable system performance, as well as maximization of detection sensitivity. To facilitate this understanding, a test bed for the study of natural background in RPMs has been established at the Oak Ridge National Laboratory. This work was performed in support of the Second Line of Defense Program's mission to enhance partner country capability to deter, detect, and interdict the illicit movement of special nuclear material. In the present work, transient increases in gamma-ray counting rates in RPMs due to rain are investigated. The increase in background activity associated with rain, which has been well documented in the field of environmental radioactivity, originates primarily from the wet-deposition of two radioactive daughters of (222)Rn, namely, (214)Pb and (214)Bi. In this study, rainfall rates recorded by a co-located weather station are compared with RPM count rates and high-purity germanium spectra. The data verify that these radionuclides are responsible for the largest environmental background fluctuations in RPMs. Analytical expressions for the detector response function in Poly-Vinyl Toluene have been derived. Effects on system performance and potential mitigation strategies are discussed. Copyright © 2014 Elsevier Ltd. All rights reserved.

Eye- and vision-related symptoms are the most frequent health problems among computer users. The findings of eye strain, tired eyes, eye irritation, burning sensation, redness, blurred vision and double vision, when appearing together, have recently been termed 'computer vision syndrome', or asthenopia. To examine the frequency and intensity of asthenopia among individuals employed in research and development departments of high-tech firms and the effects of job stress and burnout on ocular complaints, this study included 106 subjects, 42 high-tech workers (study group) and 64 bank employees (control group). All participants completed self-report questionnaires covering demographics, asthenopia, satisfaction with work environmental conditions, job-related stress and burnout. There was a significant between-group difference in the intensity of asthenopia, but not in its frequency. Burnout appeared to be a significant contributing factor to the intensity and frequency of asthenopia. This study shows that burnout is a significant factor in asthenopic complaints in high-tech workers. This manuscript analyses the effects of psychological environmental factors, such as job stress and burnout, on ocular complaints at the workplace of computer users. The findings may have an ergonomic impact on how to improve health, safety and comfort of the working environment among computer users, for better perception of the job environment, efficacy and production.

To determine the correlation between the working environment and the health status of employees in solar greenhouse, 1171 employees were surveyed. The results show the 'Greenhouse diseases' are affected by many factors. Among general uncomforts, the morbidity of the bone and joint damage is the highest and closely related to labor time and age. Planting summer squash and wax gourd more easily cause skin pruritus. Asthma-related cough, eye disease, and skin pruritus are significantly correlated with the cultivation of wax gourd. The application of inorganic fertilizer and fertigation dramatically induce the bone and joint damage. The smell of covering film greatly influence skin pruritus. Personal protection is badly scanty and normative occupational health and safety need to be completed. Copyright © 2015 The Editorial Board of Biomedical and Environmental Sciences.

Purpose and Objectives Policy, systems, and environmental approaches are recommended for preventing childhood obesity. The objective of our study was to evaluate the Healthy Lifestyles Initiative, which aimed to strengthen community capacity for policy, systems, and environmental approaches to healthy eating and active living among children and families. Intervention Approach The Healthy Lifestyles Initiative was developed through a collaborative process and facilitated by community organizers at a local children’s hospital. The initiative supported 218 partners from 170 community organizations through training, action planning, coalition support, one-on-one support, and the dissemination of materials and sharing of resources. Evaluation Methods Eighty initiative partners completed a brief online survey on implementation strategies engaged in, materials used, and policy, systems, and environmental activities implemented. In accordance with frameworks for implementation science, we assessed associations among the constructs by using linear regression to identify whether and which of the implementation strategies were associated with materials used and implementation of policy, systems, and environmental activities targeted by the initiative. Results Each implementation strategy was engaged in by 30% to 35% of the 80 survey respondents. The most frequently used materials were educational handouts (76.3%) and posters (66.3%). The most frequently implemented activities were developing or continuing partnerships (57.5%) and reviewing organizational wellness policies (46.3%). Completing an action plan and the number of implementation strategies engaged in were positively associated with implementation of targeted activities (action plan, effect size = 0.82; number of strategies, effect size = 0.51) and materials use (action plan, effect size = 0.59; number of strategies, effect size = 0.52). Materials use was positively associated with implementation of targeted activities (effect size = 0.35). Implications for Public Health Community-capacity–building efforts can be effective in supporting community organizations to engage in policy, systems, and environmental activities for healthy eating and active living. Multiple implementation strategies are likely needed, particularly strategies that involve a high level of engagement, such as training community organizations and working with them on structured action plans.

The role of field auditing in environmental quality assurance management.

PubMed

Claycomb, D R

2000-01-01

Environmental data quality improvement continues to focus on analytical laboratoryperformance with little, if any, attention given to improving the performance of field consultants responsible for sample collection. Many environmental professionals often assume that the primary opportunity for data error lies within the activities conducted by the laboratory. Experience in the evaluation of environmental data and project-wide quality assurance programs indicates that an often-ignored factor affecting environmental data quality is the manner in which a sample is acquired and handled in the field. If a sample is not properly collected, preserved, stored, and transported in the field, even the best laboratory practices and analytical methods cannot deliver accurate and reliable data (i.e., bad data in equals bad data out). Poor quality environmental data may result in inappropriate decisions regarding site characterization and remedial action. Field auditing is becoming an often-employed technique for examining the performance of the environmental sampling field team and how their performance may affect data quality. The field audits typically focus on: (1) verifying that field consultants adhere to project control documents (e.g., Work Plans and Standard Operating Procedures [SOPs]) during field operations; (2) providing third-party independent assurance that field procedures, quality assurance/ quality control (QA/QC)protocol, and field documentation are sufficient to produce data of satisfactory quality; (3) providing a defense in the event that field procedures are called into question; and (4) identifying ways to reduce sampling costs. Field audits are typically most effective when performed on a surprise basis; that is, the sampling contractor may be aware that a field audit will be conducted during some phase of sampling activities but is not informed of the specific day(s) that the audit will be conducted. The audit also should be conducted early on in the sampling program such that deficiencies noted during the audit can be addressed before the majority of field activities have been completed. A second audit should be performed as a follow-up to confirm that the recommended changes have been implemented. A field auditor is assigned to the project by matching, as closely as possible, the auditor's experience with the type of field activities being conducted. The auditor uses a project-specific field audit checklist developed from key information contained in project control documents. Completion of the extensive audit checklist during the audit focuses the auditor on evaluating each aspect of field activities being performed. Rather than examine field team performance after sampling, a field auditor can do so while the samples are being collected and can apply real-time corrective action as appropriate. As a result of field audits, responsible parties often observe vast improvements in their consultant's field procedures and, consequently, receive more reliable and representative field data at a lower cost. The cost savings and improved data quality that result from properly completed field audits make the field auditing process both cost-effective and functional.

Purpose To better understand the environmental constraints on nurse managers that impact their need for and use of decision support tools, we conducted a Cognitive Work Analysis (CWA). A complete CWA includes system analyses at five levels: work domain, decision-making procedures, decision-making strategies, social organization/collaboration, and worker skill level. Here we describe the results of the Work Domain Analysis (WDA) portion in detail then integrate the WDA with other portions of the CWA, reported previously, to generate a more complete picture of the nurse manager’s work domain. Methods Data for the WDA were obtained from semi-structured interviews with nurse managers, division directors, CNOs, and other managers (n = 20) on 10 patient care units in 3 Arizona hospitals. The WDA described the nurse manager’s environment in terms of the constraints it imposes on the nurse manager’s ability to achieve targeted outcomes through organizational goals and priorities, functions, processes, as well as work objects and resources (e.g., people, equipment, technology, and data). Constraints were identified and summarized through qualitative thematic analysis. Results The results highlight the competing priorities, and external and internal constraints that today’s nurse managers must satisfy as they try to improve quality and safety outcomes on their units. Nurse managers receive a great deal of data, much in electronic format. Although dashboards were perceived as helpful because they integrated some data elements, no decision support tools were available to help nurse managers with planning or answering “what if” questions. The results suggest both the need for additional decision support to manage the growing complexity of the environment, and the constraints the environment places on the design of that technology if it is to be effective. Limitations of the study include the small homogenous sample and the reliance on interview data targeting safety and quality. PMID:21862397

2003-04-01

The environment is a laboratory native for learning, always open and everywhere available. Environmental sciences collect knowledge into the environment and make it scientifically transferable through algorithms. Therefore the environment can be used as a gym for teaching with direct experiments many knowledge of many disciplines. For this reason into the environmental database for the Lagoon of Venice carried out at the Istituto Veneto di Scienze, Lettere ed Arti of Venice (Italy) has been organized a section for disseminating environmental knowledge (URL: www.istitutoveneto.it/venezia/divulgazione/divulgazione.htm). In this section are given information and tools to make data base contents understanding easy and to promote its use for didactical purpose. The aim is to stimulate users' curiosity and to satisfy the request of dissemination tools coming from those who work in training field. This section is divided into four chapters: Descriptions, with generalities about the types and the dynamics of environment that can be found in the Venice lagoon; Cards, with specific information about objects, phenomena and categories; Didactics, offering Training Experiences, Educational Courses and Games and Simulations. A Glossary, with technical terms and idiomatic forms completes the section. Secondary school teachers have been involved, in order to understand their requirements and their experience level for deciding contents organization. Moreover, agreement with teachers has been found on a report model allowing some standardization on cataloguing of the environmental didactics and education activities carried out within the schools.

Geometric and Colour Data Fusion for Outdoor 3D Models

Merchán, Pilar; Adán, Antonio; Salamanca, Santiago; Domínguez, Vicente; Chacón, Ricardo

2012-01-01

This paper deals with the generation of accurate, dense and coloured 3D models of outdoor scenarios from scanners. This is a challenging research field in which several problems still remain unsolved. In particular, the process of 3D model creation in outdoor scenes may be inefficient if the scene is digitalized under unsuitable technical (specific scanner on-board camera) and environmental (rain, dampness, changing illumination) conditions. We address our research towards the integration of images and range data to produce photorealistic models. Our proposal is based on decoupling the colour integration and geometry reconstruction stages, making them independent and controlled processes. This issue is approached from two different viewpoints. On the one hand, given a complete model (geometry plus texture), we propose a method to modify the original texture provided by the scanner on-board camera with the colour information extracted from external images taken at given moments and under specific environmental conditions. On the other hand, we propose an algorithm to directly assign external images onto the complete geometric model, thus avoiding tedious on-line calibration processes. We present the work conducted on two large Roman archaeological sites dating from the first century A.D., namely, the Theatre of Segobriga and the Fori Porticus of Emerita Augusta, both in Spain. The results obtained demonstrate that our approach could be useful in the digitalization and 3D modelling fields. PMID:22969327

The influence of worksite and employee variables on employee engagement in telephonic health coaching programs: a retrospective multivariate analysis.

Grossmeier, Jessica

2013-01-01

This study assessed 11 determinants of health coaching program participation. A cross-sectional study design used secondary data to assess the role of six employee-level and five worksite-level variables on telephone-based coaching enrollment, active participation, and completion. Data was provided by a national provider of worksite health promotion program services for employers. A random sample of 34,291 employees from 52 companies was selected for inclusion in the study. Survey-based measures included age, gender, job type, health risk status, tobacco risk, social support, financial incentives, comprehensive communications, senior leadership support, cultural support, and comprehensive program design. Gender-stratified multivariate logistic regression models were applied using backwards elimination procedures to yield parsimonious prediction models for each of the dependent variables. Employees were more likely to enroll in coaching programs if they were older, female, and in poorer health, and if they were at worksites with fewer environmental supports for health, clear financial incentives for participation in coaching, more comprehensive communications, and more comprehensive programs. Once employees were enrolled, program completion was greater among those who were older, did not use tobacco, worked at a company with strong communications, and had fewer environmental supports for health. Both worksite-level and employee-level factors have significant influences on health coaching engagement, and there are gender differences in the strength of these predictors.

Etiological Contributions to the Covariation Between Children’s Perceptions of Inter-parental Conflict and Child Behavioral Problems

PubMed Central

Nikolas, Molly; Klump, Kelly L.; Burt, S. Alexandra

2012-01-01

Prior work has suggested that inter-parental conflict likely plays an etiological role in child behavior problems. However, family-level measurement of inter-parental conflict in most traditional child twin studies has made it difficult to tease apart the specific causal mechanisms underlying this association. The Children’s Perception of Inter-parental Conflict scale (CPIC) provides a child-specific measurement tool for examining these questions, as its subscales tap multiple dimensions of conflict assessed from the child’s (rather than the parent’s) perspective. The current study examined (1) the degree of genetic and environmental influence on each of the CPIC subscales, and (2) etiological contributions to the covariation between the CPIC scales and parental reports of child behavioral problems. The CPIC was completed by 1,200 child twins (aged 6-11 years) from the Michigan State University Twin Registry (MSUTR). Parents completed the Child Behavior Checklist (CBCL) to assess child internalizing and externalizing behavior problems. Multivariate models were examined to evaluate the relative contributions of genetic and environmental factors to both the CPIC scales and to their overlap with child behavioral outcomes. Modeling results indicated no significant moderation of sex or age. Significant environmental overlap emerged between the CPIC conflict properties scale and child internalizing and externalizing problems. By contrast, significant genetic correlations emerged between the CPIC self-blame scale and externalizing problems as well as between the CPIC threat scale and internalizing problems. Overall, findings suggest that the subscales of the CPIC are somewhat etiologically diverse and may provide a useful tool for future investigations of possible gene-environment interplay.

A strong foundation of basic and applied research documents that the estuarine fish Fundulus heteroclitus and related species are unique laboratory and field models for understanding how individuals and populations interact with their environment. In this paper we summarize an extensive body of work examining the adaptive responses of Fundulus species to environmental conditions, and describe how this research has contributed importantly to our understanding of physiology, gene regulation, toxicology, and ecological and evolutionary genetics of teleosts and other vertebrates. These explorations have reached a critical juncture at which advancement is hindered by the lack of genomic resources for these species. We suggest that a more complete genomics toolbox for F. heteroclitus and related species will permit researchers to exploit the power of this model organism to rapidly advance our understanding of fundamental biological and pathological mechanisms among vertebrates, as well as ecological strategies and evolutionary processes common to all living organisms.

The successful integration of sample pretreatment stages, sensors, actuators and electronics in microfluidic devices enables the attainment of complete micro total analysis systems, also known as lab-on-a-chip devices. In this work, we present a novel monolithic autonomous microanalyzer that integrates microfluidics, electronics, a highly sensitive photometric detection system and a sample pretreatment stage consisting on an embedded microcolumn, all in the same device, for on-line determination of relevant environmental parameters. The microcolumn can be filled/emptied with any resin or powder substrate whenever required, paving the way for its application to several analytical processes: separation, pre-concentration or ionic-exchange. To promote its autonomous operation, avoiding issues caused by bubbles in photometric detection systems, an efficient monolithic bubble removal structure was also integrated. To demonstrate its feasibility, the microanalyzer was successfully used to determine nitrate and nitrite in continuous flow conditions, providing real time and continuous information.

In recent clinical assays, our cholera vaccine candidate strain, Vibrio cholerae 638 El Tor Ogawa, was well tolerated and immunogenic in Cuban volunteers. In this work we describe the construction of 638T, a thymidine auxotrophic version of improved environmental biosafety. In so doing, the thyA gene from V. cholerae was cloned, sequenced, mutated in vitro, and used to replace the wild-type allele. Except for its dependence on thymidine for growth in minimal medium, 638T is essentially indistinguishable from 638 in the rate of growth and morphology in complete medium. The two strains showed equivalent phenotypes with regard to motility, expression of the celA marker, colonization capacity in the infant mouse cholera model, and immunogenicity in the adult rabbit cholera model. However, the ability of this new strain to survive environmental starvation was limited with respect to that of 638. Taken together, these results suggest that this live, attenuated, but nonproliferative strain is a new, promising cholera vaccine candidate. PMID:11035753

As part of the strategies to promote health in urban areas, the Italian Society of Hygiene (SItI) has updated its recommendations for healthy, safe and sustainable housing. They were issued by an ad hoc SitI working group on the basis of the best available evidence retrieved from a review of the scientific and legal literature on the topic and in line with World Health Organisation, European Union, and other international bodies statements. SItI document includes recommendations for environmental comfort, mental and social wellbeing, environmental protection as well as the safety of people who dwell houses. In addition to typical issues (such as relative humidity parameters, ventilation, and safety rules), SItI recommendations address innovative aspects such as building compatibility between different functions, building safety management and green area design. In this context, SItI recommendations emphasise the need of a strengthened interaction between architects and public health experts to ensure the complete wellbeing in houses where people spend more than 50% of their lives.

2008-04-15

The manufacturing of modern semiconductor devices involves a complex set of nanoscale fabrication processes that are energy and resource intensive, and generate significant waste. It is important to understand and reduce the environmental impacts of semiconductor manufacturing because these devices are ubiquitous components in electronics. Furthermore, the fabrication processes used in the semiconductor industry are finding increasing application in other products, such as microelectromechanical systems (MEMS), flat panel displays, and photovoltaics. In this work we develop a library of typical gate-to-gate materials and energy requirements, as well as emissions associated with a complete set of fabrication process models used in manufacturing a modern microprocessor. In addition, we evaluate upstream energy requirements associated with chemicals and materials using both existing process life cycle assessment (LCA) databases and an economic input-output (EIO) model. The result is a comprehensive data set and methodology that may be used to estimate and improve the environmental performance of a broad range of electronics and other emerging applications that involve nano and micro fabrication.

Smart City Environmental Pollution Prevention and Control Design Based on Internet of Things

Peng, He; Bohong, Zheng; Qinpei, Kuang

2017-11-01

Due to increasingly serious urban pollution, this paper proposes an environmental pollution prevention and control system in combination with Internet of things. The system transfers data through the Internet, which also utilizes sensor, pH sensor and smoke sensor to obtain environmental data. Besides, combined with the video data acquired through monitoring, the data are transferred to data center to analyze the haze pollution, water pollution and fire disaster in environment. According to the results, multi-purpose vehicles are mobilized to complete the tasks such as spraying water to relieve haze, water source purification and fire fighting in city environment. Experiments show that the environmental pollution prevention and control system designed in this paper can automatically complete the urban environmental pollution detection, prevention and control, which thus reduces human and material resources and improves the efficiency of pollution prevention and control. Therefore, it possesses greatly practical significance to the construction of smart city.

This study aimed to assess vocal behavior in women with voice-intensive occupations to investigate differences between patients and controls and between work and leisure conditions with environmental noise level as an experimental factor. Patients with work-related voice disorders, 10 with phonasthenia and 10 with vocal nodules, were matched regarding age, profession, and workplace with 20 vocally healthy colleagues. The sound pressure level of environmental noise and the speakers' voice, fundamental frequency, and phonation ratio were registered from morning to night during 1 week with a voice accumulator. Voice data were assessed in low (≤55 dBA), moderate, and high (>70 dBA) environmental noise levels. The average environmental noise level was significantly higher during the work condition for patients with vocal nodules (73.9 dBA) and their controls (73.0 dBA) compared with patients with phonasthenia (68.3 dBA) and their controls (67.1 dBA). The average voice level and the fundamental frequency were also significantly higher during work for the patients with vocal nodules and their controls. During the leisure condition, there were no significant differences in average noise and voice level nor fundamental frequency between the groups. The patients with vocal nodules and their controls spent significantly more time and used their voices significantly more in high-environmental noise levels. High noise levels during work and demands from the occupation impact vocal behavior. Thus, assessment of voice ergonomics should be part of the work environmental management. To reduce environmental noise levels is important to improve voice ergonomic conditions in communication-intensive and vocally demanding workplaces. Copyright © 2018 The Voice Foundation.

The relationship between the environment and human fecundity and fertility remains virtually unstudied from a couple-based perspective in which longitudinal exposure data and biospecimens are captured across sensitive windows. In response, we completed the LIFE Study with methodology that intended to empirically evaluate a priori purported methodological challenges: implementation of population-based sampling frameworks suitable for recruiting couples planning pregnancy; obtaining environmental data across sensitive windows of reproduction and development; home-based biospecimen collection; and development of a data management system for hierarchical exposome data. We used two sampling frameworks (i.e., fish/wildlife licence registry and a direct marketing database) for 16 targeted counties with presumed environmental exposures to persistent organochlorine chemicals to recruit 501 couples planning pregnancies for prospective longitudinal follow-up while trying to conceive and throughout pregnancy. Enrolment rates varied from <1% of the targeted population (n = 424,423) to 42% of eligible couples who were successfully screened; 84% of the targeted population could not be reached, while 36% refused screening. Among enrolled couples, ∼ 85% completed daily journals while trying; 82% of pregnant women completed daily early pregnancy journals, and 80% completed monthly pregnancy journals. All couples provided baseline blood/urine samples; 94% of men provided one or more semen samples and 98% of women provided one or more saliva samples. Women successfully used urinary fertility monitors for identifying ovulation and home pregnancy test kits. Couples can be recruited for preconception cohorts and will comply with intensive data collection across sensitive windows. However, appropriately sized sampling frameworks are critical, given the small percentage of couples contacted found eligible and reportedly planning pregnancy at any point in time. © Published 2011.

Operational challenges for astronomical instrumentation in Antarctica: results from five years of environmental monitoring of AMICA at Dome C

NASA Astrophysics Data System (ADS)

Dolci, Mauro; Valentini, Angelo; Tavagnacco, Daniele; Di Cianno, Amico; Straniero, Oscar

2016-08-01

The Antarctic Plateau is one of the best observing sites on Earth, especially for infrared astronomy. The extremely low temperatures (down to -80°C), the low pressure (around 650 mbar) and the very dry atmosphere (PWV less than 1 mm) allow for a very clear and dark sky, as well as for a very low instrumental background. These unique properties, however, make it also very difficult to install and operate astronomical instrumentation. AMICA (Antarctic Multiband Infrared CAmera) is an instrument especially designed for Antarctic operation, whose installation at Dome C has been completed in 2013. Since then it has been continuously working over the last five years, monitoring and controlling in particular the environmental and operating conditions through a dedicated application, its Environmental Control System (ECS). The recorded behavior of AMICA highlighted a set of peculiar aspects of the site that are hard to consider a priori. Although mechanical and electronic COTS components can reliably work in thermally insulated and controlled boxes, simple insulation causes their overheating because of the air dryness and rarefaction which make the heat transfer extremely inefficient. Heat removal is also a real problem when managing heavy-duty devices like cryocoolers, whose excess power removal needs to be fast and efficient. Finally, the lack of an electrical ground generates a wide variety of transient electrical and electromagnetic phenomena which often make electronic instrumentation very unstable. A list of new recommendations is therefore presented, as a guideline for future astronomical instruments operating in Antarctica.

The relation between psychological stress at work and menstrual function was examined for 276 healthy, working, premenopausal women who participated in the California Women's Reproductive Health Study in 1990-1991. Subjects collected daily urine samples and completed a daily diary for an average of five menstrual cycles. Metabolites of estrogen and progesterone were measured in the urine, and computer algorithms were developed to characterize each cycle as ovulatory or anovulatory and to select a probable day of ovulation. A telephone interview collected information about psychological stress at work as well as other occupational, demographic, lifestyle, and environmental factors. Logistic regression was used to model stressful work and risk of anovulation (> or = 36 days without ovulating) and measures of within-woman cycle variability. Repeated measures analyses were performed on other menstrual cycle parameters. Stressful work (high demand in combination with low control) was not strongly related to an increased risk for anovulation or cycle variability or to any of the following cycle endpoints: short luteal phase (< or = 10 days), long follicular phase (> or = 24 days), long menses (> or = 8 days), or long cycle (> or = 36 days). However, women in stressful jobs had a more than doubled risk for short cycle length (< or = 24 days) compared with women not working in stressful jobs (adjusted odds ratio = 2.24, 95% confidence interval 1.09-4.59).

Characterising food environment exposure at home, at work, and along commuting journeys using data on adults in the UK.

Burgoine, Thomas; Monsivais, Pablo

2013-06-27

Socio-ecological models of behaviour suggest that dietary behaviours are potentially shaped by exposure to the food environment ('foodscape'). Research on associations between the foodscape and diet and health has largely focussed on foodscapes around the home, despite recognition that non-home environments are likely to be important in a more complete assessment of foodscape exposure. This paper characterises and describes foodscape exposure of different types, at home, at work, and along commuting routes for a sample of working adults in Cambridgeshire, UK. Home and work locations, and transport habits for 2,696 adults aged 29-60 were drawn from the Fenland Study, UK. Food outlet locations were obtained from local councils and classified by type - we focus on convenience stores, restaurants, supermarkets and takeaway food outlets. Density of and proximity to food outlets was characterised at home and work. Commuting routes were modelled based on the shortest street network distance between home and work, with exposure (counts of food outlets) that accounted for travel mode and frequency. We describe these three domains of food environment exposure using descriptive and inferential statistics. For all types of food outlet, we found very different foodscapes around homes and workplaces (with overall outlet exposure at work 125% higher), as well as a potentially substantial exposure contribution from commuting routes. On average, work and commuting environments each contributed to foodscape exposure at least equally to residential neighbourhoods, which only accounted for roughly 30% of total exposure. Furthermore, for participants with highest overall exposure to takeaway food outlets, workplaces accounted for most of the exposure. Levels of relative exposure between home, work and commuting environments were poorly correlated. Relying solely on residential neighbourhood characterisation greatly underestimated total foodscape exposure in this sample, with levels of home exposure unrelated to levels of away from home exposure. Such mis-estimation is likely to be expressed in analyses as attenuated parameter estimates, suggesting a minimal 'environmental' contribution to outcomes of interest. Future work should aim to assess exposure more completely through characterising environments beyond the residential neighbourhood, where behaviours related to food consumption are likely to occur.

Online Higher Education in the Natural Sciences

Online courses in higher education allow traditional and non-traditional students to complete course work in all disciplines with great flexibility. Courses in the Natural Sciences are no exception because the online environment allows students to collapse time and space; to access a course anywhere; to get immediate feedback, tutoring and coaching; and to receive real-time interaction between themselves and the instructor. This presentation will highlight successful examples of course content from the areas of astronomy, environmental, and earth and physical sciences. Content examples will focus on helping students use their 'environment' as part of the laboratory experience in courses traditionally thought of as lecture and laboratory courses. These examples will include real and virtual field trips, use of multimedia content, collaboration between students and faculty to design and conduct experiments and field work, and modifications to traditional lecture methods for the online environment. Dr. Karen Pearson former director of Online-Learning and Academic Technologies and Professor Science and Mathematics at the Fashion Institute of Technology (SUNY) and Dr. Joseph Liddicoat will focus on how courses in the Natural Sciences can be delivered in the online environment while maintaining high academic standards and not losing the "hands" on experience students need while completing a laboratory science course as part of a liberal arts curriculum.

Objectives To characterize the peculiarities in the training, exercise, and performance of human talent working in environmental health in Colombia. Method Documentary and database reviews. Surveys and semi-structured interviews. Results Approximately 70 % of professionals in the area of environmental health work in health management, food engineering, environmental engineering, sanitary engineering, veterinary medicine, and pharmaceutical chemistry. 63 % of technologists belong to the field of sanitation technology. Only 20 % of surveyed educational institutions apply the competence approach to training to their students and the identification of occupational characteristics in the labor market is only used at the undergraduate level as a criterion of academic analysis and design. Only 20 % of educational institutions identify educational trends in Colombian and or international environmental health as a contribution to their programs. In prospective practices, the following topics to be strengthened were identified: risk factor identfication, measurement, and control; design and implementation of mechanisms for controlling environmental risks; forms of interdisciplinary work between the natural, social and health sciences; preventative and environmental protection measures and the concept of environment (natural, social, and cultural). Conclusion The human talent currently working in environmental health in the country is concentrated in primary care activities (inspection, monitoring and control) and a large spread exists in mission processes and competences, both professionally and technologically. A lack of coordination between the environmental sector and the education sector can be observed. A great diversity exists among the profiles offered by the different educational programs related to environmental health.

BACKGROUND North Carolina has the third largest community college system in the nation and reaches residents in all 100 counties. Few studies have focused on the health of employees who work at these institutions. We assessed the current status of and interest in supporting health promotion efforts among North Carolina Community College System members. METHODS North Carolina Community College System presidents completed a brief 15-item survey assessing support for and interest in offering health promotion programs. Wellness coordinators completed a 60-item questionnaire assessing current health promotion programming and organizational, environmental, and policy supports for health promotion efforts. Onsite interviews with a sub-sample of Wellness coordinators offered insights into important implementation considerations. We examined differences by campus size with Fisher's exact test. RESULTS All 58 presidents (100%) and 51 wellness coordinators (88%) completed surveys. Ten percent of colleges offered comprehensive employee health promotion programming. Most offered physical activity (70.6%), tobacco cessation (51.0%), weight loss/management (49.0%), and/or nutrition counseling (47.1%). Larger colleges were more likely to offer programming and environmental support. Nearly all presidents (89.7%) believed it is "very" or "extremely" important to offer health promotion programs to employees, and most (84%) were interested in promoting health through a university partnership. LIMITATIONS Despite very high survey response rates from presidents and wellness coordinators at each community college, onsite interviews were only done at select campuses, limiting the generalizability and scope of conclusions derived from interview data. CONCLUSION Community colleges in North Carolina are promising settings for promoting employee health. Findings identify resources, barriers, and technical assistance that could facilitate greater adoption and implementation of programs. ©2017 by the North Carolina Institute of Medicine and The Duke Endowment.

To analyze the relationship between voice disorders and work in a group of Community Health Agents (CHA). The subjects of this study were 65 CHA working in the city of São Paulo. Thefiinstrument used for data collection was an adaptation of the questionnaire named Conditions of Vocal Production - Teachers (CPV-P). The results were keyed in twice and submitted to statistical analysis, in order to verify: the self-reported frequency of voice disorder frequency of present vocal symptoms, the association among the three most frequently reported present symptoms, and environmental and organizational aspects of work. Of the 65 (100%) CHA in the study, 37 (56.9%) self-reported having present or past vocal disorders. The most frequently reported present symptoms were: dry throat, tiredness when speaking, and burning sensation in the throat. There was significant association between: taking work to home, having personal items stolen, police intervention, violence against employees and vocal symptom dry throat, not having enough time to complete all tasks, difficulty in leaving work, inadequate furniture, intense physical strain, objects stolen from the health unit, racism and vocal symptom tiredness when speaking, dust, job dissatisfaction, work stress, building destruction, drug issues, and vocal symptom burning in throat. Based on the obtained results, the initial hypothesis of association between the development of vocal disorders among the subjects and the adversities present in their work environment and organization was confirmed.

The Indoor Environmental Quality (IEQ) refers to the quality of the environment in relation to the health and well-being of the occupants. It is a holistic concept, which considers several categories, each related to a specific environmental parameter. This article describes a low-cost and open-source hardware architecture able to detect the indoor variables necessary for the IEQ calculation as an alternative to the traditional hardware used for this purpose. The system consists of some sensors and an Arduino board. One of the key strengths of Arduino is the possibility it affords of loading the script into the board’s memory and letting it run without interfacing with computers, thus granting complete independence, portability and accuracy. Recent works have demonstrated that the cost of scientific equipment can be reduced by applying open-source principles to their design using a combination of the Arduino platform and a 3D printer. The evolution of the 3D printer has provided a new means of open design capable of accelerating self-directed development. The proposed nano Environmental Monitoring System (nEMoS) instrument is shown to have good reliability and it provides the foundation for a more critical approach to the use of professional sensors as well as for conceiving new scenarios and potential applications.

To identify the socio-environmental, personal and behavioural factors that are longitudinally predictive of changes in adolescents' fast-food intake. Population-based longitudinal cohort study. Participants from Minnesota schools completed in-class assessments in 1999 (Time 1) while in middle school and mailed surveys in 2004 (Time 2) while in high school. A racially, ethnically and socio-economically diverse sample of adolescents (n 806). Availability of unhealthy food at home, being born in the USA and preferring the taste of unhealthy foods were predictive of higher fast-food intake after 5 years among both males and females. Among females, personal and behavioural factors, including concern about weight and use of healthy weight-control techniques, were protective against increased fast-food intake. Among males, socio-environmental factors, including maternal and friends' concern for eating healthy food and maternal encouragement to eat healthy food, were predictive of lower fast-food intake. Sports team participation was a strong risk factor for increased fast-food intake among males. Our findings suggest that addressing socio-environmental factors such as acculturation and home food availability may help reduce fast-food intake among adolescents. Additionally, gender-specific intervention strategies, including working with boys' sports teams, family members and the peer group, and for girls, emphasizing the importance of healthy weight-maintenance strategies and the addition of flavourful and healthy food options to their diet, may help reduce fast-food intake.

Phytoremediation of landfill leachate

DOE Office of Scientific and Technical Information (OSTI.GOV)

Jones, D.L.; Williamson, K.L.; Owen, A.G.

Leachate emissions from landfill sites are of concern, primarily due to their toxic impact when released unchecked into the environment, and the potential for landfill sites to generate leachate for many hundreds of years following closure. Consequently, economically and environmentally sustainable disposal options are a priority in waste management. One potential option is the use of soil-plant based remediation schemes. In many cases, using either trees (including short rotation coppice) or grassland, phytoremediation of leachate has been successful. However, there are a significant number of examples where phytoremediation has failed. Typically, this failure can be ascribed to excessive leachate applicationmore » and poor management due to a fundamental lack of understanding of the plant-soil system. On balance, with careful management, phytoremediation can be viewed as a sustainable, cost effective and environmentally sound option which is capable of treating 250 m{sup 3} ha{sup -1} yr{sup -1}. However, these schemes have a requirement for large land areas and must be capable of responding to changes in leachate quality and quantity, problems of scheme establishment and maintenance, continual environmental monitoring and seasonal patterns of plant growth. Although the fundamental underpinning science is well understood, further work is required to create long-term predictive remediation models, full environmental impact assessments, a complete life-cycle analysis and economic analyses for a wide range of landfill scenarios.« less

Aqueous phase hydration and hydrate acidity of perfluoroalkyl and n:2 fluorotelomer aldehydes.

Rayne, Sierra; Forest, Kaya

2016-01-01

The SPARC software program and comparative density functional theory (DFT) calculations were used to investigate the aqueous phase hydration equilibrium constants (Khyd) of perfluoroalkyl aldehydes (PFAlds) and n:2 fluorotelomer aldehydes (FTAlds). Both classes are degradation products of known industrial compounds and environmental contaminants such as fluorotelomer alcohols, iodides, acrylates, phosphate esters, and other derivatives, as well as hydrofluorocarbons and hydrochlorofluorocarbons. Prior studies have generally failed to consider the hydration, and subsequent potential hydrate acidity, of these compounds, resulting in incomplete and erroneous predictions as to their environmental behavior. In the current work, DFT calculations suggest that all PFAlds will be dominantly present as the hydrated form in aqueous solution. Both SPARC and DFT calculations suggest that FTAlds will not likely be substantially hydrated in aquatic systems or in vivo. PFAld hydrates are expected to have pKa values in the range of phenols (ca. 9 to 10), whereas n:2 FTAld hydrates are expected to have pKa values ca. 2 to 3 units higher (ca. 12 to 13). In order to avoid spurious modeling predictions and a fundamental misunderstanding of their fate, the molecular and/or dissociated hydrate forms of PFAlds and FTAlds need to be explicitly considered in environmental, toxicological, and waste treatment investigations. The results of the current study will facilitate a more complete examination of the environmental fate of PFAlds and FTAlds.

Tank waste remediation system multi-year work plan

DOE Office of Scientific and Technical Information (OSTI.GOV)

Not Available

The Tank Waste Remediation System (TWRS) Multi-Year Work Plan (MYWP) documents the detailed total Program baseline and was constructed to guide Program execution. The TWRS MYWP is one of two elements that comprise the TWRS Program Management Plan. The TWRS MYWP fulfills the Hanford Site Management System requirement for a Multi-Year Program Plan and a Fiscal-Year Work Plan. The MYWP addresses program vision, mission, objectives, strategy, functions and requirements, risks, decisions, assumptions, constraints, structure, logic, schedule, resource requirements, and waste generation and disposition. Sections 1 through 6, Section 8, and the appendixes provide program-wide information. Section 7 includes a subsectionmore » for each of the nine program elements that comprise the TWRS Program. The foundation of any program baseline is base planning data (e.g., defendable product definition, logic, schedules, cost estimates, and bases of estimates). The TWRS Program continues to improve base data. As data improve, so will program element planning, integration between program elements, integration outside of the TWRS Program, and the overall quality of the TWRS MYWP.

1994-09-01

The Tank Waste Remediation System (TWRS) Multi-Year Work Plan (MYWP) documents the detailed total Program baseline and was constructed to guide Program execution. The TWRS MYWP is one of two elements that comprise the TWRS Program Management Plan. The TWRS MYWP fulfills the Hanford Site Management System requirement for a Multi-Year Program Plan and a Fiscal-Year Work Plan. The MYWP addresses program vision, mission, objectives, strategy, functions and requirements, risks, decisions, assumptions, constraints, structure, logic, schedule, resource requirements, and waste generation and disposition. Sections 1 through 6, Section 8, and the appendixes provide program-wide information. Section 7 includes a subsectionmore » for each of the nine program elements that comprise the TWRS Program. The foundation of any program baseline is base planning data (e.g., defendable product definition, logic, schedules, cost estimates, and bases of estimates). The TWRS Program continues to improve base data. As data improve, so will program element planning, integration between program elements, integration outside of the TWRS Program, and the overall quality of the TWRS MYWP. The MYWP establishes the TWRS baseline objectives to store, treat, and immobilize highly radioactive Hanford waste in an environmentally sound, safe, and cost-effective manner. The TWRS Program will complete the baseline mission in 2040 and will incur costs totalling approximately 40 billion dollars. The summary strategy is to meet the above objectives by using a robust systems engineering effort, placing the highest possible priority on safety and environmental protection; encouraging {open_quotes}out sourcing{close_quotes} of the work to the extent practical; and managing significant but limited resources to move toward final disposition of tank wastes, while openly communicating with all interested stakeholders.« less

Superfund record of decision amendment (EPA Region 5): Metamora Landfill Site, Metamora, MI, August 28, 1996

DOE Office of Scientific and Technical Information (OSTI.GOV)

NONE

The United States Environmental Protection Agency (U.S. EPA) is changing a portion of the remedy selected in the operable unit one (OU1) Record of Decision (ROD) dated September 30, 1986, for the Metamora Landfill Site. Operable Unit 1 ROD (OU1 ROD) addresses the remediation of drummed waste and contaminated soils in Drum Area 1 and Drum Area 4. OU1 ROD selected off-site incineration of the drums and soils in Drum Area 1 and Drum Area 4. State lead remedial action work began in the spring of 1989 and continued until December 1990. During the summer of 1990, off-site incineration capacitymore » became extremely limited and drums awaiting disposal began to accumulate at the site. In addition, many more drums were discovered than originally estimated in the Remedial Design. In April of 1991 a settlement was reached that addressed the completion of all remedial activity remaining at the site, including the completion of OU1.« less

Spatially controlled immobilisation of biomolecules: A complete approach in green chemistry

NASA Astrophysics Data System (ADS)

Grinenval, Eva; Nonglaton, Guillaume; Vinet, Françoise

2014-01-01

The development of 'green' sensors is a challenging task in the field of biomolecule sensing, for example in the detection of cardiac troponin-I (cTnI). In the present work a complete approach in green chemistry was developed to create chemically active patterns for the immobilisation of biological probes. This key technology is discussed on the basis of the twelve green chemistry principles, and is a combination of surface patterning by spotting and surface chemistries modified by molecular vapour deposition. The (1H,1H,2H,2H)-perfluorodecyltrichlorosilane (FDTS) was used as a novel anti-adsorption layer while the 3,4-epoxybutyltrimethoxysilane (EBTMOS) was used to immobilise probes. Oligonucleotides and the anti-cTnI antibody were studied. The spatially controlled immobilisation of probes was characterised by fluorescence. The demonstrated surface modification has broad applications in areas such as diagnostics and bio-chemical sensing. Moreover, the environmental impacts of surface patterning and surface chemistry were discussed from a 'greenness' point of view.

Experimental observation of complete and anticipation synchronization of heterogeneous oscillators using a common dynamical environment

NASA Astrophysics Data System (ADS)

Singla, Tanu; Chandrasekhar, E.; Singh, B. P.; Parmananda, P.

2014-12-01

Complete and anticipation synchronization of nonlinear oscillators from different origins is attempted experimentally. This involves coupling these heterogeneous oscillators to a common dynamical environment. Initially, this phenomenon was studied using two parameter mismatched Chua circuits. Subsequently, three different timeseries: a) x variable of the Lorenz oscillator b) the X-component of Earth's magnetic field and c) per-day temperature variation of the Region Santa Cruz in Mumbai, India are environmentally coupled, under the master-slave scenario, with a Chua circuit. Our results indicate that environmental coupling is a potent tool to provoke complete and anticipation synchronization of heterogeneous oscillators from distinct origins.

1996-01-01

A summary of work accomplished under Technical Task Agreement by the Marshall Space Flight Center (MSFC) documents activities regarding the Environmental Control and Life Support Systems (ECLSS) of the International Space Station (ISS) program. These MSFC activities were in-line to the designing, the development, the testing, and the flight of ECLSS equipment. MSFC's unique capabilities for performing integrated system testing and analyses, and its ability to perform some tasks cheaper and faster to support ISS program needs are the basis for the Technical Task Agreement activities. Tasks were completed in the Water Recovery Systems, Air Revitalization Systems, and microbiology areas. The results of each task is described in this summary report.

Recycling microcavity optical biosensors.

PubMed

Hunt, Heather K; Armani, Andrea M

2011-04-01

Optical biosensors have tremendous potential for commercial applications in medical diagnostics, environmental monitoring, and food safety evaluation. In these applications, sensor reuse is desirable to reduce costs. To achieve this, harsh, wet chemistry treatments are required to remove surface chemistry from the sensor, typically resulting in reduced sensor performance and increased noise due to recognition moiety and optical transducer degradation. In the present work, we suggest an alternative, dry-chemistry method, based on O₂ plasma treatment. This approach is compatible with typical fabrication of substrate-based optical transducers. This treatment completely removes the recognition moiety, allowing the transducer surface to be refreshed with new recognition elements and thus enabling the sensor to be recycled.

A fuzzy set approach for reliability calculation of valve controlling electric actuators

NASA Astrophysics Data System (ADS)

Karmachev, D. P.; Yefremov, A. A.; Luneva, E. E.

2017-02-01

The oil and gas equipment and electric actuators in particular frequently perform in various operational modes and under dynamic environmental conditions. These factors affect equipment reliability measures in a vague, uncertain way. To eliminate the ambiguity, reliability model parameters could be defined as fuzzy numbers. We suggest a technique that allows constructing fundamental fuzzy-valued performance reliability measures based on an analysis of electric actuators failure data in accordance with the amount of work, completed before the failure, instead of failure time. Also, this paper provides a computation example of fuzzy-valued reliability and hazard rate functions, assuming Kumaraswamy complementary Weibull geometric distribution as a lifetime (reliability) model for electric actuators.

Nevada National Security Site Industrial Sites Project Closeout - 12498

DOE Office of Scientific and Technical Information (OSTI.GOV)

Cabble, Kevin; Krauss, Mark; Matthews, Pat

The U.S. Department of Energy (DOE), National Nuclear Security Administration Nevada Site Office is responsible for environmental restoration (ER) at the Nevada National Security Site (NNSS). This includes remediation at Industrial Sites where past nuclear testing activities and activities that supported nuclear testing may have or are known to have resulted in the release of contaminants into the environment. Industrial Sites at the NNSS have included nuclear facilities that supported the nuclear rocket/missile development programs, gas stations, landfills, spill sites, ordnance sites, and numerous other waste disposal and release sites. The NNSS Industrial Sites activities neared completion at the endmore » of fiscal year 2011 while other activities required under the Federal Facility Agreement and Consent Order (FFACO) and part of the same NNSS ER Project are forecasted to extend to 2027 or beyond. With the majority of Industrial Sites corrective action units (CAUs) completed (more than 250 CAUs and over 1,800 corrective action sites), it was determined that an activity closeout process should be implemented to ensure that the work completed over the past 15 years is well documented in a comprehensive and concise summary. While the process used to close each individual CAU is described in approved documents, no single document describes in summary fashion the work completed to close the many individual Industrial Sites. The activity closeout process will be used to develop an Industrial Sites closeout document that describes these years of work. This document will summarize the number of Industrial Sites closed under the FFACO and provide general descriptions of projects, contaminants removed, and sites closed in place with corresponding Use Restrictions. Other pertinent information related to Industrial Sites work such as the project history, closure decisions, historical declarations, remediation strategies, and final CAU status will be included in the closeout document, along with a table listing each CAU and corresponding corrective action sites within each CAU. Using this process of conducting the activity closeout and developing a closeout document may prove useful for other ER projects within the DOE complex in describing how a long period of ER can be summarized in a single document. The NNSS Industrial Sites activities were completed over the span of 15 years and involved the investigation, cleanup or Use Restriction, and closure of more than 260 CAUs and over 1,800 sites. These activities will conclude in FY 2012 (with the exception of one CAU). In order to capture the work completed over this length of time and document decisions made during the activities, a closeout effort was initiated. The closeout will review the work conducted during the Industrial Sites activities and produce a single document that summarizes Industrial Sites activities. This closeout is being conducted at an interim stage in the overall NNSA/NSO ER Project since the Soils and UGTA activities will continue for a number of years, but the completion of the Industrial Sites project warrants conducting a closeout now while personnel are available and information is still current. The process followed by NNSA/NSO in conducing project closeout for the Industrial Sites portion of the ER program may prove useful within the DOE complex in demonstrating how a large ER project can be summarized.

Post-Closure Land Jurisdiction Transfer to the US Fish and Wildlife Service at Rocky Flats: Surviving the Safari Through Old Records and Other Lessons Learned

DOE Office of Scientific and Technical Information (OSTI.GOV)

Schiesswohl, S.; Hanson, M.

The U.S. Department of Energy's (DOE's) Rocky Flats Site (Rocky Flats), located near Denver, Colorado, was listed on the Comprehensive Environmental Response, Compensation, and Liability Act National Priorities List (NPL) in 1989. Subsequent cleanup and closure activities were completed in October 2005 and the final remedy was selected in September 2006. The remedy is 'no further action' for the generally un-impacted Peripheral Operable Unit (OU), formerly known as the Buffer Zone, and institutional and physical controls with continued monitoring for the Central OU, formerly the industrialized area. The Peripheral OU has been deleted from the NPL and jurisdiction over themore » majority of land in that OU (3,953 acres) was transferred to the U.S. Fish and Wildlife Service (USFWS) on July 12, 2007, to establish the Rocky Flats National Wildlife Refuge. The remaining approximately 929 acres in the Peripheral OU were retained by DOE's Office of Legacy Management where outstanding mineral leases and mining operations exist. As mineral rights are purchased or mining operations and mineral leases are completed and fully reclaimed, jurisdiction of portions of the 929 acres will also be transferred to USFWS for inclusion into the refuge. During the almost 2 years since cleanup and closure work was completed at Rocky Flats, DOE and USFWS have worked the specific legal parameters, timing, and constraints of the 3,953-acre transfer. Many lessons have been learned, based on these early experiences. (authors)« less

The paper presents the results of a study of the gravimetric and counting concentrations of respirable asbestos fibers while working with sand-and-crushed stone mixtures, obtained from the concentration of chrysotile asbestos, at distances of 25, 50, and 100 m from the working place, as well as in a car saloon when the electric train passes along the area of these operations following an hour, a day, and a year after the completion of work, in warm and colds seasons of a year. It is concluded that the use of asbestos-containing sand-and-crushed stone mixtures on the railway leads to a higher anthropogenic asbestos load on the population living in the railway right-of-way, on railway workers and passengers. In this connection, it is necessary to evaluate risk factors of asbestos-induced diseases among the above contingents. The authors consider that due to the fact that asbestos-containing sand-and-crushed stone mixtures are well wetted with water, followed by the formation of a firm surface crust that prevents dust formation, as well as the short duration and rare frequency of operations relating their change, it is necessary to irrigate the repair areas with water or surfactant liquids after work termination.

Radiation damage and waste management options for the SOMBRERO final focus system and neutron dumps

DOE Office of Scientific and Technical Information (OSTI.GOV)

Latkowski, J F; Meier, W R; Reyes, S

1999-08-09

Previous studies of the safety and environmental aspects of the SOMBRERO inertial fusion energy (IFE) power plant design did not completely address the issues associated with the final focus system. While past work calculated neutron fluences for a grazing incidence metal mirror (GIMM) and a final focus mirror, scattering off of the final optical component was not included, and thus, fluences in the final focus mirror were significantly underestimated. In addition, past work did not consider neutron-induced gamma-rays. Finally, power plant lifetime waste volumes may have been underestimated as neutron activation of the neutron dumps and building structure were notmore » addressed. In the present work, a modified version of the SOMBRERO target building is presented where a significantly larger open solid-angle fraction (5%) is used to enhance beam smoothing of a diode-pumped solid-state laser (DPSSL). The GIMMs are replaced with transmissive fused silica wedges and have been included in three -dimensional neutron and photon transport calculations. This work shows that a power plant with a large open solid-angle fraction, needed for beam smoothing with a DPSSL, is acceptable from tritium breeding, and neutron activation points-of-view.« less

Prompting Technology and Persons With Dementia: The Significance of Context and Communication.

PubMed

Braley, Rachel; Fritz, Rochelle; Van Son, Catherine R; Schmitter-Edgecombe, Maureen

2018-06-12

Smart home auto-prompting has the potential to increase the functional independence of persons with dementia (PWDs) and decrease caregiver burden as instrumental activities of daily living (IADLs) are completed at home. To improve prompting technologies, we sought to inductively understand how PWDs responded to auto-prompting while performing IADL tasks. Fifteen PWDs completed eight IADLs in a smart home testbed and received a hierarchy of verbal auto-prompts (indirect, direct, multimodal) as needed for task completion. Two researchers viewed archived videos and recorded the observed behaviors of the PWDs and their reflections watching the PWDs. Using qualitative descriptive methods, an interdisciplinary analytic team reviewed transcripts and organized data into themes using content analysis. Context and Communication emerged as the major themes, suggesting that positive user experiences will require auto-prompting systems to account for a multitude of contextual factors (individual and environmental) such as level of cognitive impairment, previous exposure to task, and familiarity of environment. Communicating with another human rather than an automated prompting system may be important if individuals begin to exhibit signs of stress while completing activities. Additional work is needed to create auto-prompting systems that provide specific, personalized, and flexible prompts. Holistic conceptualization of "successful task completion" is needed and a positive end-user experience will be key to utility. Such systems will benefit from including positive reinforcement, training, and exploration of how, and whether, direct human involvement can be minimized during the provision of in-home care.

This study examined the rate of return to work, and to find demographic, clinical and functional factors associated with successful re-employment after in-patient rehabilitation. We performed a cross-sectional cohort study of Singaporeans aged 15 and above who underwent inpatient rehabilitation in a Singapore hospital between 2000 and 2007. Phone interviews were conducted in 2007 to 2008, via a structured questionnaire to evaluate factors of return to work. Four hundred and eight patients met with the inclusion criteria, and 123 participants completed the questionnaire. Forty-five (44.7%) participants successfully returned to work with a mean time of 7 months post-discharge. Statistical significant differences were found between the "return to work" group and "non-return to work" group based on age group (p=0.04), education level (p=0.001), pre-morbid job category (0.013) and functional status (p<0.0005) as determined by Functional Independence Measure scores. Cox regression analysis controlling the period between discharge and survey indicated that higher FIM scores and higher education level predicted successful re-employment. This result re-affirmed the importance of functional status to the success of return-to-work in Singapore. Further qualitative studies might be useful in exploring the social or environmental factors affecting return-to-work outcomes.

Environmental geology in the United States: Present practice and future training needs

NASA Astrophysics Data System (ADS)

Lundgren, Lawrence

Environmental geology as practiced in the United States confronts issues in three large areas: Threats to human society from geologic phenomena (geologic hazards); impacts of human activities on natural systems (environmental impact), and natural-resource management. This paper illustrates present U.S. practice in environmental geology by sampling the work of 7 of the 50 state geological surveys and of the United States Geological Survey as well. Study of the work of these agencies provides a basis for identifying avenues for the training of those who will deal with environmental issues in the future. This training must deal not only with the subdisciplines of geology but with education to cope with the ethical, interdisciplinary, and public-communication aspects of the work of the environmental geologist.

Mapping Global Urban Extent and Intensity for Environmental Monitoring and Modeling

NASA Astrophysics Data System (ADS)

Schneider, A.; Friedl, M. A.

2007-05-01

The human dimensions of global environmental change have received increased attention in policy, decision- making, research, and even the media. However, the influence of urban areas in global change processes is still often assumed to be negligible. Although local environmental conditions such as the urban heat island effect are well-documented, little or no work has focused on cross-scale interactions, or the ways in which local urban processes cumulatively impact global changes. Given the rapid rates of rural-urban migration, economic development and urban spatial expansion, it is becoming increasingly clear that the `ecological footprint' of cities may play a critical role in environmental changes at regional and global scales. Our understanding of the cumulative impacts of urban areas on natural systems has been limited foremost by a lack of reliable, accurate data on current urban form and extent at the global scale. The data sets that have emerged to fill this gap (LandScan, GRUMP, nighttime lights) suffer from a number of limitations that prevent widespread use. Building on our early efforts with MODIS data, our current work focuses on: (1) completing a new, validated map of global urban extent; and (2) developing methods to estimate the subpixel fraction of impervious surface, vegetation, and other land cover types within urbanized areas using coarse resolution satellite imagery. For the first task, a technique called boosting is used to improve classification accuracy and provides a means to integrate 500 m resolution MODIS data with ancillary data sources. For the second task, we present an approach for estimating percent cover that relies on continuous training data for a full range of city types. These exemplars are used as inputs to fuzzy neural network and regression tree algorithms to predict fractional amounts of land cover types with increased accuracy. Preliminary results for a global sample of 100 cities (which vary in population size, level of economic development, and spatial extent) show good agreement with the expected morphology in each region.

Another key aspect of the NNSS mission is Environmental Management program, which addresses the environmental legacy from historic nuclear weapons related activities while also ensuring the health and safety of present day workers, the public, and the environment as current and future missions are completed. The Area 5 Radioactive Waste Management site receives low-level and mixed low-level waste from some 28 different generators from across the DOE complex in support of the legacy clean-up DOE Environmental Management project. Without this capability, the DOE would not be able to complete the clean up and proper disposition of these wastes. The program includes environmental protection, compliance, and monitoring of the air, water, plants, animals, and cultural resources at the NNSS. Investigation and implementation of appropriate corrective actions to address the contaminated ground water facilities and soils resulting from historic nuclear testing activities, the demolition of abandoned nuclear facilities, as well as installation of ground water wells to identify and monitor the extent of ground water contamination.

Pro-environmental actions, climate change, and defensiveness: do self-affirmations make a difference to people's motives and beliefs about making a difference?

PubMed

Sparks, Paul; Jessop, Donna C; Chapman, James; Holmes, Katherine

2010-09-01

Social concerns with the imperative of environmentally sustainable life-styles sit rather awkwardly with ideas about the widespread denial of global environmental problems. Given the very obvious threat and denial dimensions to these issues, we conducted two studies assessing the impact of self-affirmation manipulations on people's beliefs and motives regarding pro-environmental actions. In Study 1, participants (N=125) completed a self-affirmation task and read information on the threat of climate change. Results showed that the self-affirmation manipulation resulted in lower levels of denial and greater perceptions of personal involvement in relation to climate change. In Study 2, participants (N=90) completed a self-affirmation task and read some information on recycling. Findings showed a beneficial effect of a self-affirmation manipulation on intentions to increase recycling behaviour (among lower recyclers). The results are discussed in relation to the potential benefits of self-affirmation manipulations for promoting pro-environmental actions.

A case study of the development of environmental action projects from the framework of participatory action research within two middle school classrooms

NASA Astrophysics Data System (ADS)

Charmatz, Kim

The purpose of this study was to understand student and teacher empowerment through a socially critical environmental education perspective. The main research question guiding this study was: How do participants make sense of a learning experience in which students design and carry out an environmental action project in their community? This study used participatory action research and critical theory as practical and theoretical frameworks. These frameworks were relevant as this study sought to examine social change, power, and relationships through participants' experiences. The context of this study was within one seventh and one eighth grade classroom participating in environmental projects. The study was conducted in spring 2005 with an additional follow-up data collection period during spring 2006. The school was located in a densely populated metropolitan suburb. Fifty-three students, a teacher researcher, and three science teachers participated. Data sources were written surveys, scores on Middle School Environmental Literacy Survey Instrument (MSELI), observations, interviews, and student work. This study used a mixed methodological approach. Quantitative data analysis involved dependent samples t-test scores on the MSELI before and after the completion of the projects. Qualitative data were analyzed using an inductive analysis approach. This study has implications for educators interested in democratic education. Environmental action projects provide a context for students and teachers to learn interdisciplinary content knowledge, develop personal beliefs, and learn ways to take action in their communities. This pedagogy has the potential to increase cooperation, communication, and tensions within school communities. Students' participation in the development of environmental action projects may lead to feelings of empowerment or being able to make a difference in their community, as an individual or member of a group. Future research is needed to discern why participants experience this type of educational experience differently, for example, how does the type of environmental action project influence individual and group empowerment?

Shyu, Conrad; Cavileer, Timothy D.; Nagler, James J.

2011-02-01

Environmental estrogens have been the subject of intense research due to their documented detrimental effects on the health of fish and wildlife and their potential to negatively impact humans. A complete understanding of how these compounds affect health is complicated because environmental estrogens are a structurally heterogeneous group of compounds. In this work, computational molecular dynamics simulations were utilized to predict the binding affinity of different compounds using rainbow trout (Oncorhynchus mykiss) estrogen receptors (ERs) as a model. Specifically, this study presents a comparison of the binding affinity of the natural ligand estradiol-17{beta} to the four rainbow trout ER isoformsmore » with that of three known environmental estrogens 17{alpha}-ethinylestradiol, bisphenol A, and raloxifene. Two additional compounds, atrazine and testosterone, that are known to be very weak or non-binders to ERs were tested. The binding affinity of these compounds to the human ER{alpha} subtype is also included for comparison. The results of this study suggest that, when compared to estradiol-17{beta}, bisphenol A binds less strongly to all four receptors, 17{alpha}-ethinylestradiol binds more strongly, and raloxifene has a high affinity for the {alpha} subtype only. The results also show that atrazine and testosterone are weak or non-binders to the ERs. All of the results are in excellent qualitative agreement with the known in vivo estrogenicity of these compounds in the rainbow trout and other fishes. Computational estimation of binding affinities could be a valuable tool for predicting the impact of environmental estrogens in fish and other animals.« less

Modeling flows and concentrations of nine engineered nanomaterials in the Danish environment.

2015-05-22

Predictions of environmental concentrations of engineered nanomaterials (ENM) are needed for their environmental risk assessment. Because analytical data on ENM-concentrations in the environment are not yet available, exposure modeling represents the only source of information on ENM exposure in the environment. This work provides material flow data and environmental concentrations of nine ENM in Denmark. It represents the first study that distinguishes between photostable TiO₂ (as used in sunscreens) and photocatalytic TiO₂ (as used in self-cleaning surfaces). It also provides first exposure estimates for quantum dots, carbon black and CuCO₃. Other ENM that are covered are ZnO, Ag, CNT and CeO₂. The modeling is based for all ENM on probability distributions of production, use, environmental release and transfer between compartments, always considering the complete life-cycle of products containing the ENM. The magnitude of flows and concentrations of the various ENM depends on the one hand on the production volume but also on the type of products they are used in and the life-cycles of these products and their potential for release. The results reveal that in aquatic systems the highest concentrations are expected for carbon black and photostable TiO₂, followed by CuCO₃ (under the assumption that the use as wood preservative becomes important). In sludge-treated soil highest concentrations are expected for CeO₂ and TiO₂. Transformation during water treatments results in extremely low concentrations of ZnO and Ag in the environment. The results of this study provide valuable environmental exposure information for future risk assessments of these ENM.

Occupational and environmental risk factors for chronic rhinosinusitis: a systematic review.

Chronic rhinosinusitis (CRS) is a prevalent and disabling paranasal sinus disease, with a likely multifactorial etiology potentially including hazardous occupational and environmental exposures. We completed a systematic review of the occupational and environmental literature to evaluate the quality of evidence of the role that hazardous exposures might play in CRS. We searched PubMed for studies of CRS and following exposure categories: occupation, employment, work, industry, air pollution, agriculture, farming, environment, chemicals, roadways, disaster, and traffic. We abstracted information from the final set of articles across 6 primary domains: study design; population; exposures evaluated; exposure assessment; CRS definition; and results. We identified 41 articles from 1080 manuscripts: 37 occupational risk papers, 1 environmental risk paper, and 3 papers studying both categories of exposures. None of the 41 studies used a CRS definition consistent with current diagnostic guidelines. Exposure assessment was generally dependent on self-report or binary measurements of exposure based on industry of employment. Only grain, dairy, and swine operations among farmers were evaluated by more than 1 study using a common approach to defining CRS, but employment in these settings was not consistently associated with CRS. The multiple other exposures did not meet quality standards for reporting associations or were not evaluated by more than 1 study. The current state of the literature allows us to make very few conclusions about the role of hazardous occupational or environmental exposures in CRS, leaving a critical knowledge gap regarding potentially modifiable risk factors for disease onset and progression. © 2015 ARS-AAOA, LLC.

Environmental Criteria in the Spanish Public Works Procurement Process.

Fuentes-Bargues, José Luis; González-Cruz, Mª Carmen; González-Gaya, Cristina

2017-02-18

Green Public Procurement (GPP) is defined as a process of contracting products, services, and works with the least possible damage to the environment during their life cycle. In order to improve the knowledge about GPP, a study of the use of environmental tendering criteria in the Spanish public construction sector has been performed. The results of this study show that the use of environmental criteria in Spanish public sector construction procurement is low in comparison to a certain group of countries, known as "Green 7", in the European Union. Environmental criteria is the fourth criterion in importance, but its weight in the global of the process is much lower than other criteria such as price, memory of the construction process and the delivery time. National administrations use environmental criteria more frequently because they have more resources and staff training about environmental issues. Environmental criteria are more used in the tendering of civil projects and works whose budget exceeds ten million euro due to the environmental impact of these kind and/or size of projects.

Due to the predominant usage of short-read sequencing to date, most bacterial genome sequences reported in the last years remain at the draft level. This precludes certain types of analyses, such as the in-depth analysis of genome plasticity. Here we report the finalized genome sequence of the environmental strain Aeromonas salmonicida subsp. pectinolytica 34mel, for which only a draft genome with 253 contigs is currently available. Successful completion of the transposon-rich genome critically depended on the PacBio long read sequencing technology. Using finalized genome sequences of A. salmonicida subsp. pectinolytica and other Aeromonads, we report the detailed analysis of the transposon composition of these bacterial species. Mobilome evolution is exemplified by a complex transposon, which has shifted from pathogenicity-related to environmental-related gene content in A. salmonicida subsp. pectinolytica 34mel. Obtaining the complete, circular genome of A. salmonicida subsp. pectinolytica allowed us to perform an in-depth analysis of its mobilome. We demonstrate the mobilome-dependent evolution of this strain's genetic profile from pathogenic to environmental.

Geothermal Development and the Use of Categorical Exclusions Under the National Environmental Policy Act of 1969 (Presentation)

DOE Office of Scientific and Technical Information (OSTI.GOV)

Levine, A.; Young, K. R.

2014-09-01

The federal environmental review process under the National Environmental Policy Act of 1969 (NEPA) can be complex and time consuming. Currently, a geothermal developer may have to complete the NEPA process multiple times during the development of a geothermal project. One mechanism to reduce the timeframe of the federal environmental review process for activities that do not have a significant environmental impact is the use of Categorical Exclusions (CXs), which can exempt projects from having to complete an Environmental Assessment or Environmental Impact Statement. This study focuses primarily on the CX process and its applicability to geothermal exploration. In thismore » paper, we: Provide generalized background information on CXs, including previous NEPA reports addressing CXs, the process for developing CXs, and the role of extraordinary circumstances; Examine the history of the Bureau of Land Management's (BLM) geothermal CXs; Compare current CXs for oil, gas, and geothermal energy; Describe bills proposing new statutory CXs; Examine the possibility of standardizing geothermal CXs across federal agencies; and Present analysis from the Geothermal NEPA Database and other sources on the potential for new geothermal exploration CXs. As part of this study, we reviewed Environmental Assessments (EAs) conducted in response to 20 geothermal exploration drilling permit applications (Geothermal Drilling Permits or Notices of Intents) since the year 2001, the majority of which are from the last 5 years. All 20 EAs reviewed for this study resulted in a Finding of No Significant Impact (FONSI). While many of these FONS's involved proponent proposed or federal agency required mitigation, this still suggests it may be appropriate to create or expand an exploration drilling CX for geothermal, which would have a significant impact on reducing geothermal exploration timelines and up-front costs. Ultimately, federal agencies tasked with permitting and completing environmental reviews for geothermal exploration drilling activities and/or legislative representatives are the responsible parties to discuss the merits and implementation of new or revised CXs for geothermal development.« less

The Delivery of Health Promotion and Environmental Health Services; Public Health or Primary Care Settings?

2018-05-07

The WHO Regional Office for Europe developed a set of public health functions resulting in the ten Essential Public Health Operations (EPHO). Public health or primary care settings seem to be favorable to embrace all actions included into EPHOs. The presented paper aims to guide readers on how to assign individual health promotion and environmental health services to public health or primary care settings. Survey tools were developed based on EPHO 2, 3 and 4; there were six key informant surveys out of 18 contacted completed via e-mails by informants working in Denmark on health promotion and five face-to-face interviews were conducted in Australia (Melbourne and Victoria state) with experts from environmental health, public health and a physician. Based on interviews, we developed a set of indicators to support the assignment process. Population or individual focus, a system approach or one-to-one approach, dealing with hazards or dealing with effects, being proactive or reactive were identified as main element of the decision tool. Assignment of public health services to one of two settings proved to be possible in some cases, whereas in many there is no clear distinction between the two settings. National context might be the one which guides delivery of public health services.

Youth appraisals of inter-parental conflict and genetic and environmental contributions to attention-deficit hyperactivity disorder: examination of GxE effects in a twin sample.

2012-05-01

Identification of gene x environment interactions (GxE) for attention-deficit hyperactivity disorder (ADHD) is a crucial component to understanding the mechanisms underpinning the disorder, as prior work indicates large genetic influences and numerous environmental risk factors. Building on prior research, children's appraisals of self-blame were examined as a psychosocial moderator of latent etiological influences on ADHD via biometric twin models, which provide an omnibus test of GxE while managing the potential confound of gene-environment correlation. Participants were 246 twin pairs (total n = 492) ages 6-16 years. ADHD behaviors were assessed via mother report on the Child Behavior Checklist. To assess level of self-blame, each twin completed the Children's Perception of Inter-parental Conflict scale. Two biometric GxE models were fit to the data. The first model revealed a significant decrease in genetic effects and a significant increase in unique environmental influences on ADHD with increasing levels of self-blame. These results generally persisted even after controlling for confounding effects due to gene-environment correlation in the second model. Results suggest that appraisals of self-blame in relation to inter-parental conflict may act as a key moderator of etiological contributions to ADHD.

Romantic Relationship Satisfaction Moderates the Etiology of Adult Personality.

2016-01-01

The heritability of major normative domains of personality is well-established, with approximately half the proportion of variance attributed to genetic differences. In the current study, we examine the possibility of gene × environment interaction (G×E) for adult personality using the environmental context of intimate romantic relationship functioning. Personality and relationship satisfaction are significantly correlated phenotypically, but to date no research has examined how the genetic and environmental components of variance for personality differ as a function of romantic relationship satisfaction. Given the importance of personality for myriad outcomes from work productivity to psychopathology, it is vital to identify variables present in adulthood that may affect the etiology of personality. In the current study, quantitative models of G×E were used to determine whether the genetic and environmental influences on personality differ as a function of relationship satisfaction. We drew from a sample of now-adult twins followed longitudinally from adolescence through age 29. All participants completed the Multidimensional Personality Questionnaire (MPQ) and an abbreviated version of the Dyadic Adjustment Scale. Biometric moderation was found for eight of the eleven MPQ scales examined: well-being, social potency, negative emotionality, alienation, aggression, constraint, traditionalism, and absorption. The pattern of findings differed, suggesting that the ways in which relationship quality moderates the etiology of personality may depend on the personality trait.

Photodegradation behaviour of estriol: An insight on natural aquatic organic matter influence.

Oliveira, Cindy; Lima, Diana L D; Silva, Carla Patrícia; Otero, Marta; Esteves, Valdemar I

2016-09-01

Estriol (E3) is one of the steroidal estrogens ubiquitously found in the aquatic environment, photodegradation being an important pathway for the elimination of such endocrine disrupting compounds. However, it is important to understand how environmentally important components present in aquatic matrices, such as organic matter, may affect their photodegradation. The main objective of this work was to investigate the photodegradation of E3 in water, under simulated solar radiation, as well as the effect of humic substances (HS - humic acids (HA), fulvic acids (FA) and XAD-4 fraction) in E3 photodegradation. Moreover, the photodegradation behaviour of E3 when present in different environmental aquatic matrices (fresh, estuarine and waste water samples) was also assessed. Results showed a completely different E3 degradation rate depending on the aquatic matrix. In ultrapure water the half-life obtained was about 50 h, while in presence of HS it varied between 5 and 10 h. Then, half-life times between 1.6 and 9.5 h were determined in environmental samples, in which it was observed that the matrix composition contributed up to 97% for the overall E3 photodegradation. Therefore, E3 photodegradation in the considered aquatic matrices was mostly caused by photosensitizing reactions (indirect photodegradation). Copyright © 2016 Elsevier Ltd. All rights reserved.

The purpose of Recycling Mentors was to implement an intergenerational, service-learning program focused on promoting recycling and environmental awareness among students enrolled in Community Health (HEA 301) and Current Issues in Gerontology (GRN 440/540) and adults older than 60 years. Recycling Mentors was conducted in New Hanover County (NHC), North Carolina, where a moderate climate and coastal location attracts many tourists, retirees, and college students. A community like NHC is a good place to implement service-learning that educates both students and older adults about the benefits of recycling to individual health and the environment. During the Fall 2009 semester, undergraduate and graduate students completed institutional review board training and then conducted the program with older adults. The education component of Recycling Mentors included a pre/post survey, brochure, and scheduled visits. Overall, Recycling Mentors was positive service-learning experience with students identifying salient outcomes such as learning about recycling and the environment and working with older adults. In addition, teaching the education component of Recycling Mentors was good practice for students who will be the future health professionals. While service-learning and environmentally themed projects are common, a program that combines the 2 like Recycling Mentors is unique and has the potential to motivate individual change while positively impacting the local community and the environment.

We examined community perspectives and experiences with fracking in Doddridge County, West Virginia, USA as part of a larger assessment to investigate the potential health impacts associated with fracking in neighboring Maryland, USA. In November 2013, we held two focus groups with community residents who had been impacted by fracking operations and conducted field observations in the impacted areas. Employing grounded theory, we conducted qualitative analysis to explore emergent themes related to direct and indirect health impacts of fracking. Three components of experience were identified, including (a) meanings of place and identity, (b) transforming relationships, and (c) perceptions of environmental and health impacts. Our findings indicate that fracking contributes to a disruption in residents' sense of place and social identity, generating widespread social stress. Although community residents acknowledged the potential for economic growth brought about by fracking, rapid transformations in meanings of place and social identity influenced residents' perceptions of environmental and health impacts. Our findings suggest that in order to have a more complete understanding of the health impacts of fracking, future work must consider the complex linkages between social disruption, environmental impacts, and health outcomes through critical engagements with communities undergoing energy development.

To present the development and feasibility testing of a sociocultural environmental change intervention strategy aimed at integrating physical activity into workplace routine. Randomized, controlled, post-test only, intervention trial. Setting. Los Angeles County Department of Health Services' worksites. Four hundred forty-nine employees, predominantly sedentary, overweight, middle-aged women of color, distributed across 26 meetings. A single 10-min exercise break during work time involving moderate intensity, low-impact aerobic dance and calisthenic movements to music. Primary-level of participation, particularly among sedentary staff; secondary-self-perceived health status, satisfaction with current fitness level, and mood/affective state. More than 90% of meeting attendees participated in the exercises. Among completely sedentary individuals, intervention participants' self-perceived health status ratings were significantly lower than controls' (OR = 0.17; 95% CI = 0.05, 0.60; P = 0.0003). Among all respondents not regularly physically active, intervention participants' levels of satisfaction with fitness were more highly correlated with self-ranked physical activity stage of change (r = 0.588) than the control participants' (r = 0.376, z = -2.32, p = 0.02). Among the completely sedentary, control participants reported significantly higher levels of energy than did intervention participants (P < 0.01). Captive audiences may be engaged in brief bouts of exercise as a part of the workday, regardless of physical activity level or stage of change. This experience may also appropriately erode sedentary individuals' self-perception of good health and fitness, providing motivation for adoption of more active lifestyles.

Evaluation of patients' attitudes to their care during oral and maxillofacial surgical outpatient consultations: the importance of waiting times and quality of interaction between patient and doctor.

Knowing what patients think about their care is fundamental to the provision of an effective, quality service, and it can help to direct change and reduce costs. Much of the work in oral and maxillofacial departments concerns the treatment of outpatients, but as little is known about what they think about their care, we aimed to find out which aspects were associated with satisfaction. Consecutive patients (n=244) who attended the oral and maxillofacial outpatient department at Southampton University Hospital NHS Foundation Trust over a 7-day period were given a questionnaire to complete before and after their consultation. It included questions with Likert scale responses on environmental, procedural, and interactive aspects of the visit, and a 16-point scale to rank their priorities. A total of 187 patients (77%) completed the questionnaires. No association was found between expected (p=0.93) or actual (p=0.41) waiting times, and 90% of patients were satisfied with their visit. Seeing the doctor, having confidence in the treatment plan, being listened to, and the ability of the doctor to recognise their personal needs, were ranked as important. Environmental and procedural aspects were considered the least important. These findings may be of value in the development of services to improve patient-centred care.

2018-01-03

Continuous quality improvement (CQI) collaboration has not eliminated the morbidity variability seen among neonatal intensive care units (NICUs). Factors other than inconstant application of potentially better practices (PBPs) might explain divergent proficiency. Measure a composite morbidity score and determine whether cultural, environmental and cognitive factors distinguish high proficiency from lower proficiency NICUs. Retrospective analysis using a risk-adjusted composite morbidity score (Benefit Metric) and cultural survey focusing on very low birth weight (VLBW) infants from 39 NICUs, years 2000-2014. The Benefit Metric and yearly variance from the group mean was rank-ordered by NICU. A comprehensive survey was completed by each NICU exploring whether morbidity variance correlated with CQI methodology, cultural, environmental and/or cognitive characteristics. 58 272 VLBW infants were included, mean (SD) age 28.2 (3.0) weeks, birth weight 1031 (301) g. The 39 NICU groups' Benefit Metric improved 40%, from 80 in 2000 to 112 in 2014 (P<0.001). 14 NICUs had composite morbidity scores significantly better than the group, 16 did not differ and 9 scored below the group mean. The 14 highest performing NICUs were characterised by more effective team work, superior morale, greater problem-solving expectations of providers, enhanced learning opportunities, knowledge of CQI fundamentals and more generous staffing. Cultural, environmental and cognitive characteristics vary among NICUs perhaps more than traditional CQI methodology and PBPs, possibly explaining the inconstancy of VLBW infant morbidity reduction efforts. High proficiency NICUs foster spirited team work and camaraderie, sustained learning opportunities and support of favourable staffing that allows problem solving and widespread involvement in CQI activities. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Background The World Trade Center (WTC) attacks exposed thousands of workers to hazardous environmental conditions and psychological trauma. In 2002, to assess the health of these workers, Congress directed the National Institute for Occupational Safety and Health to establish the WTC Medical Monitoring and Treatment Program. This program has established a large cohort of WTC rescue, recovery, and cleanup workers. We previously documented extensive pulmonary dysfunction in this cohort related to toxic environmental exposures. Objectives Our objective in this study was to describe mental health outcomes, social function impairment, and psychiatric comorbidity in the WTC worker cohort, as well as perceived symptomatology in workers’ children. Methods Ten to 61 months after the WTC attack, 10,132 WTC workers completed a self-administered mental health questionnaire. Results Of the workers who completd the questionnaire, 11.1% met criteria for probable post-traumatic stress disorder (PTSD), 8.8% met criteria for probable depression, 5.0% met criteria for probable panic disorder, and 62% met criteria for substantial stress reaction. PTSD prevalence was comparable to that seen in returning Afghanistan war veterans and was much higher than in the U.S. general population. Point prevalence declined from 13.5% to 9.7% over the 5 years of observation. Comorbidity was extensive and included extremely high risks for impairment of social function. PTSD was significantly associated with loss of family members and friends, disruption of family, work, and social life, and higher rates of behavioral symptoms in children of workers. Conclusions Working in 9/11 recovery operations is associated with chronic impairment of mental health and social functioning. Psychological distress and psychopathology in WTC workers greatly exceed population norms. Surveillance and treatment programs continue to be needed. PMID:18795171

In response to various legislative mandates, the US Environmental Protection Agency (USEPA) formed its Endocrine Disruptor Screening Program (EDSP), which in turn, formed the basis of a tiered testing strategy to determine the potential of pesticides, commercial chemicals, and environmental contaminants to disrupt the endocrine system. The first tier of tests is intended to detect the potential for endocrine disruption mediated through estrogen, androgen, or thyroid pathways, whereas the second tier is intended to further characterize the effects on these pathways and to establish a dose-response relationship for adverse effects. One of these tier 2 tests, the Medaka Extended One Generation Reproduction Test (MEOGRT), was developed by the USEPA for the EDSP and, in collaboration with the Japanese Ministry of the Environment, for the Guidelines for the Testing of Chemicals of the Organisation for Economic Co-operation and Development (OECD). The MEOGRT protocol was iteratively modified based on knowledge gained after the successful completion of 9 tests with variations in test protocols. The present study describes both the final MEOGRT protocol that has been published by the USEPA and the OECD, and the iterations that provided valuable insights into nuances of the protocol. The various tests include exposure to 17β-estradiol, 4-t-octylphenol, o,p'- dichlorodiphenyltrichloroethane, 4-chloro-3-methylphenol, tamoxifen, 17β-trenbolone, vinclozolin, and prochloraz.

The Base Enivronmental Management System (BEMS) is a Web-based application program for managing and tracking audits by the Environmental Office of Stennis Space Center in conformity with standard 14001 of the International Organization for Standardization (ISO 14001). (This standard specifies requirements for an environmental-management system.) BEMS saves time by partly automating what were previously manual processes for creating audit checklists; recording and tracking audit results; issuing, tracking, and implementing corrective-action requests (CARs); tracking continuous improvements (CIs); and tracking audit results and statistics. BEMS consists on an administration module and an auditor module. As its name suggests, the administration module is used to administer the audit. It helps administrators to edit the list of audit questions; edit the list of audit locations; assign manditory questions to locations; track, approve, and edit CARs; and edit completed audits. The auditor module is used by auditors to perform audits and record audit results: It helps the auditors to create audit checklists, complete audits, view completed audits, create CARs, record and acknowledge CIs, and generate reports from audit results.

A methodology was developed for diagnosing industrial work, which includes questionnaire, observation, measurements, data collection and statistical analysis. A survey was conducted to investigate the relationship between job satisfaction and factors that affect work design in 2 automotives manufacturing companies in Malaysia. A basic work design model was proposed. The aim of this model was to determine the factors that influence employees' perception towards their work. A set of multiple-choice questionnaires was developed and data was collected by interviewing employees at a production plant. The survey focused on job and environmental factors. The results supported the proposed model and showed that job and environmental factors were significantly related to job satisfaction. They highlighted the significant influence of age, work experience and marital status on job satisfaction. Further, environmental factors, especially the surroundings, context dependence and the building's function, also had a significant impact on job satisfaction.

In this report, I will discuss the tasks and projects I have completed while working as an electrical engineering intern during the spring semester of 2016 at NASA Kennedy Space Center. In the field of software development, I completed tasks for the G-O Caching Mobile App and the Asbestos Management Information System (AMIS) Web App. The G-O Caching Mobile App was written in HTML, CSS, and JavaScript on the Cordova framework, while the AMIS Web App is written in HTML, CSS, JavaScript, and C# on the AngularJS framework. My goals and objectives on these two projects were to produce an app with an eye-catching and intuitive User Interface (UI), which will attract more employees to participate; to produce a fully-tested, fully functional app which supports workforce engagement and exploration; to produce a fully-tested, fully functional web app that assists technicians working in asbestos management. I also worked in hardware development on the Integrated Display and Environmental Awareness System (IDEAS) wearable technology project. My tasks on this project were focused in PCB design and camera integration. My goals and objectives for this project were to successfully integrate fully functioning custom hardware extenders on the wearable technology headset to minimize the size of hardware on the smart glasses headset for maximum user comfort; to successfully integrate fully functioning camera onto the headset. By the end of this semester, I was able to successfully develop four extender boards to minimize hardware on the headset, and assisted in integrating a fully-functioning camera into the system.

Given the onset of alcohol use, neurological sensitivity, and enhanced panic-relevant vulnerability, adolescence is a key period in which to study the documented linkage between alcohol and panic-related problems. The current study was designed to build upon and uniquely extend extant work via (1) utilization of well-established experimental psychopathology techniques, and (2) evaluation of unique associations between alcohol use and panic symptoms after controlling for theoretically-relevant behavioral, environmental, and individual difference variables (i.e., age, gender, negative affectivity, anxiety sensitivity, child and parent tobacco use, and parental panic disorder). Participants were 111 community-recruited adolescents ages 12–17 years (M = 15.76 years; n = 50 girls). Youth completed a battery of well-established questionnaires and a voluntary hyperventilation challenge, and parents present at the laboratory completed a structured clinical interview. Adolescent alcohol use was categorized as Non-Users, Experimenters, or Users. Panic symptoms were indexed via retrospective self-report and adolescents’ response to a biological challenge procedure (i.e., voluntary hyperventilation). After controlling for theoretically-relevant covariates, Users evidenced elevated panic-relevant symptoms and responding compared to Non-Users; Experimenters did not differ from Non-Users. Findings suggest alcohol use history is uniquely associated with panic symptomatology among youth, including “real-time” reactivity elicited by a laboratory challenge. While there is significant work yet to be done, these data advance extant work and lay the groundwork for the types of sophisticated designs that will be needed to answer the most pressing and complex questions regarding the link between alcohol use and panic symptoms among adolescents.

The use of this material under current conditions is supported by existing information. This material was evaluated for genotoxicity, repeated dose toxicity, developmental and reproductive toxicity, local respiratory toxicity, phototoxicity/photoallergenicity, skin sensitization, as well as environmental safety. Data show that this material is not genotoxic nor does it have skin sensitization potential. The reproductive and local respiratory toxicity endpoints were completed using the TTC (Threshold of Toxicological Concern) for a Cramer Class I material (0.03 and 1.4 mg/day, respectively). The developmental toxicity endpoint was completed using linalool (CAS # 78-70-6), dehydrolinalool (CAS # 29171-20-8) and cinnamic acid (CAS # 621-82-9) as suitable read across analogs, which provided a MOE > 100. The repeated dose toxicity endpoint was completed using data on the target material which provided a MOE > 100. The phototoxicity/photoallergenicity endpoint was completed based on suitable UV spectra. The environmental endpoint was completed as described in the RIFM Framework. Copyright © 2016 Elsevier Ltd.

Invasion should decline with species richness, yet the relationship is inconsistent. Species richness, however, is a product of species pool size and biotic filtering. Invasion may increase with richness if large species pools represent weaker environmental filters. Measuring species pool size and the proportion realised locally (completeness) may clarify diversity-invasion relationships by separating environmental and biotic effects, especially if species' life-history stage and origin are accounted for. To test these relationships, we added seeds and transplants of 15 native and alien species into 29 grasslands. Species pool size and completeness explained more variation in invasion than richness alone. Although results varied between native and alien species, seed establishment and biotic resistance to transplants increased with species pool size, whereas transplant growth and biotic resistance to seeds increased with completeness. Consequently, species pools and completeness represent multiple independent processes affecting invasion; accounting for these processes improves our understanding of invasion. © 2016 John Wiley & Sons Ltd/CNRS.

Developments in environmental auditing by supreme audit institutions.

PubMed

Van Leeuwen, Sylvia

2004-02-01

At the end of the 1980s, Supreme Audit Institutions (SAIs) became aware of their responsibility towards the environment and environmental policy. In this article, the development of environmental auditing by SAIs during the last 10 years is presented, as well as the current state of the art. The description is based on the results of three questionnaire surveys held in 1994, 1997, and 2000 by the INTOSAI Working Group in Environmental Auditing. In most countries, the government has stipulated some form of environmental policy, and the SAI has a mandate to carry out regularity and/or performance audits. The activities of SAIs have developed substantially since 1993. Nowadays, environmental auditing is a substantial and regular part of the audit work of more than half of the SAIs. Environmental problems are often transboundary in nature. SAIs can contribute to international environmental cooperation by auditing the compliance of their national government with international environmental obligations and commitments. The INTOSAI Working Group on environmental auditing wants to enhance this type of audit and has provided guidelines for the audit process and the selection of international agreements. Moreover, cooperation between SAIs is a good method to exchange experiences and to learn from each other.

Life Cycle Assessment is a tool to assess, in a systematic way, the environmental aspects and its potential environmental impacts and resources used throughout a product's life cycle. It is widely accepted and considered as one of the most powerful tools to support decision-making processes used in ecodesign and sustainable production in order to learn about the most problematic parts and life cycle phases of a product and to have a projection for future improvements. However, since Life Cycle Assessment is a cost and time intensive method, companies do not intend to carry out a full version of it, exceptmore » for large corporate ones. Especially for small and medium sized enterprises, which do not have enough budget for and knowledge on sustainable production and ecodesign approaches, focusing only on the most important possible environmental aspect is unavoidable. In this direction, finding the right environmental aspect to work on is crucial for the companies. In this study, a multi-criteria decision-making methodology, Analytic Network Process is proposed to select the most relevant environmental aspect. The proposed methodology aims at providing a simplified environmental assessment to producers. It is applied for a hand blender, which is a member of the Electrical and Electronic Equipment family. The decision criteria for the environmental aspects and relations of dependence are defined. The evaluation is made by the Analytic Network Process in order to create a realistic approach to inter-dependencies among the criteria. The results are computed via the Super Decisions software. Finally, it is observed that the procedure is completed in less time, with less data, with less cost and in a less subjective way than conventional approaches. - Highlights: • We present a simplified environmental assessment methodology to support LCA. • ANP is proposed to select the most relevant environmental aspect. • ANP deals well with the interdependencies between aspects and impacts. • The methodology is less subjective, less complicated, and less time–money consuming. • The proposed methodology is suitable for use by SMEs.« less

Work environment and disability pension-- an 18-year follow-up study in a Norwegian working population.

To investigate the associations between work environment indicators and health- related work disability. A health survey of 5,749 working 40-42-year-old Norwegians from Nordland County were linked to a national register for disability pension during a follow-up of over 18 years. The risk for disability pension following various self-reported physical and psychosocial work environmental exposures (individual and cumulative) were estimated using Cox regression analysis. Both cumulative physical and psychosocial work environmental exposures were associated with an increased risk for disability pension, although this association was attenuated for most variables after adjusting for health and education. An increase in five poor psychosocial work environmental exposures was associated with a 22% increased risk for disability (adjusted hazard ratio, aHR, 1.22, 95% CI 1.04-1.44), whereas a similar increase in five poor physical work environmental exposures was associated with a 29% increased risk (aHR, 1.29, 95% CI 1.16-1.44). There were no indications of statistical interaction between either sex or education and work exposures. People who report a poor work environment are at a higher risk for subsequent work disability. This finding suggests that improving working conditions may be an area of intervention in order to reduce the number of people who leave the labour market with a disability pension.

2015-08-01

Personal and professional experiences influence teachers' perceptions of their ability to implement environmental science curricula and to positively impact students' learning. The purpose of this study was twofold: to determine what influence, if any, an intensive field-based life science course and service learning had on preservice teachers' self-efficacy for teaching about the environment and to determine which aspects of the combined field-based course/service learning preservice teachers perceived as effective for enhancing their self-efficacy. Data were collected from class documents and written teaching reflections of 38 middle-level preservice teachers. Some participants ( n = 18) also completed the Environmental Education Efficacy Belief Instrument at the beginning and end of the semester. Both qualitative and quantitative data analyses indicated a significant increase in PSTs' personal efficacies for environmental teaching, t(17) = 4.50, p = .000, d = 1.30, 95 % CI (.33, .90), but not outcome expectancy, t(17) = 1.15, p = .268, d = .220, 95 % CI (-.06, .20). Preservice teachers reported three aspects of the course as important for enhancing their self-efficacies: learning about ecological concepts through place-based issues, service learning with K-5 students and EE curriculum development. Data from this study extend prior work by indicating that practical experiences with students were not the sole factor in shaping PSTs' self-efficacy; learning ecological concepts and theories in field-based activities grounded in the local landscape also influenced PSTs' self-efficacy.

Reflexivity, knowledge and ecological awareness: premises for responsible action in the hospital work environment.

2009-01-01

The article aims to analyze the interface of reflexivity, knowledge and ecologic awareness in the context of hospital work, based on data collected in a qualitative case study carried out at a public hospital. Field observation data and interviews are discussed in the light of sociologic and philosophic references. Workers expressed the interface between knowledge and action, in which there is a cycle of lack of knowledge, automatism in the actions and lack of environmental awareness, posing limits to individual awareness and to responsibility towards environmental preservation. Increased debate and education, including the environmental issue, are needed in the context of hospital work. Although hospital work is reflexively affected by the environmental problem, that does not guarantee the reorientation of practices and responsible action towards the environment.

Steam flooding from mine workings, a viable alternative

DOE Office of Scientific and Technical Information (OSTI.GOV)

Ayler, M.F.; Brechtel, C.

1987-05-01

The advent of steam flooding has given new life to several fields in California, substantially increasing the recoverable reserve. This process can be combined with a newly developed concept combining petroleum and mining technology. By placing mine workings 100 ft, more or less, below the bottom of the reservoir, it is possible to safely drill wells upward through the reservoir and complete them in such a way that all produced cuttings and fluids are contained within closed pipelines. Each completed well could serve as a steam injection well with continuous gravity-produced oil from the same well. As all fluids wouldmore » flow by gravity to a collection pipeline, the only needed pumps would be at the discharge within the mine shaft. Mine shafts serving the oil field could be placed in environmentally optimum sites roughly one mile apart, eliminating many of the visually objectionable disturbances. Production wells could be placed on one acre or even closer spacing, whatever good engineering dictates. Automatic controls can continuously monitor and control production from each well. Assuming one-acre well spacing, continuous steam flooding, and production from each well, a detailed analysis of anticipated mining costs indicate oil production costs under $5/bbl are possible. Even at $10/BO, a positive cash flow within two years after the start of shaft sinking is expected.« less

Psychological adaptation to extreme environments has been examined from several perspectives. In this study, two Australian teams, each consisting of six male crew members, completed computer-administered questionnaires twice weekly during 100-day traverses around the Lambert Glacier Basin, Antarctica. Only small trends were noted when data were aggregated at the group level, which is consistent with the findings of others. Data were then analyzed using pooled time-series regression. These analyses incorporated personality characteristics, environmental factors, and interpersonal factors as predictors of Group Tensions, Personal Morale, Emotional State, Cognitive Readiness, and the Team's Work Life. Most of the psychological discomfort and problems that occurred appeared to be within the individual or between individuals. They did not affect all members of the group equally.

The eROSITA X-ray observatory that will be launched on board the Russian Spectrum-RG mission comprises seven X-ray telescopes, each with its own mirror assembly (mirror module + X-ray baffle), electron deflector, filter wheel, and CCD camera with its control electronics. The completed flight mirror modules are undergoing many thorough X-ray tests at the PANTHER X-ray test facility after delivery, after being mated with the X-ray baffle, and again after both the vibration and thermal-vacuum tests. A description of the work done with mirror modules/assemblies and the test results obtained will be reported here. We report also on the environmental tests that have been performed on the eROSITA telescope qualification model.

Dinges, David F.

1998-01-01

This project had three broad goals: (1) to identify environmental and organismic risks to performance of long-haul cockpit crews; (2) to assess how cognitive and psychomotor vigilance performance, and subjective measures of alertness, were affected by work-rest schedules typical of long-haul cockpit crews; and (3) to determine the alertness-promoting effectiveness of behavioral and technological countermeasures to fatigue on the flight deck. During the course of the research, a number of studies were completed in cooperation with the NASA Ames Fatigue Countermeasures Program. The publications emerging from this project are listed in a bibliography in the appendix. Progress toward these goals will be summarized below according to the period in which it was accomplished.

1996-08-01

The cleanup of oiled shorelines has generally been by mechanical, labor-intensive means. The use of a chemical shoreline cleaner to assist in water-flushing oil from the surfaces can result in more complete and more rapid cleaning. Not only is the cleaning process more efficient, but it can also be less environmentally damaging since there is potentially much less human intrusion and stress on the biological community. This paper describes research and applications of COREXIT 9580 shoreline cleaner for treatment of oiled shorelines, including four recent applications in Puerto Rico, Bermuda, Texas and Nova Scotia. Research work on shoreline vegetation, suchmore » as mangroves, has also demonstrated the potential use of this product to save and restore oiled vegetation.« less

2002-02-15

Active polymer gels expand and contract in response to certain environmental stimuli, such as the application of an electric field or a change in the pH level of the surroundings. This ability to achieve large, reversible deformations with no external mechanical loading has generated much interest in the use of these gels as biomimetic actuators and "artificial muscles". In previous work, a thermodynamically consistent finite-elastic constitutive model has been developed to describe the mechanical and actuation behaviours of active polymer gels. The mechanical properties were characterized by a free-energy function, and the model uses an evolving internal variable to describe the actuation state. In this work, an evolution law for the internal variable is determined from free actuation experiments on a poly(vinyl alcohol)poly(acrylic acid) (PVAPAA) gel. The complete finite-elastic/evolution law constitutive model is then used to predict the response of the PVA-PAA gel to isotonic and isometric loading and actuation. The model is shown to give relatively good agreement with experimental results.

Environmental hazards of automobile mechanics in Ibadan, Nigeria.

PubMed

Omokhodion, F O

1999-01-01

A cross sectional survey was conducted among automobile mechanics and technicians in Ibadan to determine the socio-demographic characteristics and environmental hazards of these workers. Three hundred workers were interviewed. All respondents were males aged between 13 and 72 years of age. Educational attainment was poor, with only 20% of respondents having completed secondary education. Sanitation facilities were inadequate. Forty percent of workshops provided facilities for refuse disposal. Of the 33 workshops visited, only 1 provided toilet facilities. Most workers used facilities in neighbouring residential premises. Only three workshops (9%) had designated eating areas. Occupational exposure to petrol was common to all trades. Other occupational exposures were to petrochemicals such as engine oil and brake oil. Protective clothing was not used by the majority of workers. Only 25 (8%) respondents were wearing overalls at the time of our visit. This findings illustrate the typical work conditions of workers in small scale industries. There is a need for health education programmes about occupational and non-occupational diseases. This and other health promotion activities can be organized through the unions.

Adaptations and mechanisms of human heat acclimation: Applications for competitive athletes and sports.

PubMed

Périard, J D; Racinais, S; Sawka, M N

2015-06-01

Exercise heat acclimation induces physiological adaptations that improve thermoregulation, attenuate physiological strain, reduce the risk of serious heat illness, and improve aerobic performance in warm-hot environments and potentially in temperate environments. The adaptations include improved sweating, improved skin blood flow, lowered body temperatures, reduced cardiovascular strain, improved fluid balance, altered metabolism, and enhanced cellular protection. The magnitudes of adaptations are determined by the intensity, duration, frequency, and number of heat exposures, as well as the environmental conditions (i.e., dry or humid heat). Evidence is emerging that controlled hyperthermia regimens where a target core temperature is maintained, enable more rapid and complete adaptations relative to the traditional constant work rate exercise heat acclimation regimens. Furthermore, inducing heat acclimation outdoors in a natural field setting may provide more specific adaptations based on direct exposure to the exact environmental and exercise conditions to be encountered during competition. This review initially examines the physiological adaptations associated with heat acclimation induction regimens, and subsequently emphasizes their application to competitive athletes and sports. © 2015 John Wiley & Sons A/S.

Fine, George F.; Cavanagh, Leon M.; Afonja, Ayo; Binions, Russell

2010-01-01

Metal oxide semiconductor gas sensors are utilised in a variety of different roles and industries. They are relatively inexpensive compared to other sensing technologies, robust, lightweight, long lasting and benefit from high material sensitivity and quick response times. They have been used extensively to measure and monitor trace amounts of environmentally important gases such as carbon monoxide and nitrogen dioxide. In this review the nature of the gas response and how it is fundamentally linked to surface structure is explored. Synthetic routes to metal oxide semiconductor gas sensors are also discussed and related to their affect on surface structure. An overview of important contributions and recent advances are discussed for the use of metal oxide semiconductor sensors for the detection of a variety of gases—CO, NOx, NH3 and the particularly challenging case of CO2. Finally a description of recent advances in work completed at University College London is presented including the use of selective zeolites layers, new perovskite type materials and an innovative chemical vapour deposition approach to film deposition.

Public participation in watershed management: International practices for inclusiveness

NASA Astrophysics Data System (ADS)

Perkins, Patricia E. (Ellie)

This paper outlines a number of examples from around the world of participatory processes for watershed decision-making, and discusses how they work, why they are important, their social and ecological potential, and the practical details of how to start, expand and develop them. Because of long-standing power differentials in all societies along gender, class and ethnic lines, equitable public participation requires the recognition that different members of society have different kinds of relationships with the environment in general, and with water in particular. From a range of political perspectives, inclusive participatory governance processes have many benefits. The author has recently completed a 5 year project linking universities and NGOs in Brazil and Canada to develop methods of broadening public engagement in local watershed management committees, with a special focus on gender and marginalized communities. The innovative environmental education and multi-lingual international public engagement practices of the Centre for Socio-Environmental Knowledge and Care of the La Plata Basin (which spans Brazil, Argentina, Uruguay, Paraguay and Bolivia) are also discussed in this paper.

Nitrate promotes biological oxidation of sulfide in wastewaters: experiment at plant-scale.

Biogenic production of sulfide in wastewater treatment plants involves odors, toxicity and corrosion problems. The production of sulfide is a consequence of bacterial activity, mainly sulfate-reducing bacteria (SRB). To prevent this production, the efficiency of nitrate addition to wastewater was tested at plant-scale by dosing concentrated calcium nitrate (Nutriox) in the works inlet. Nutriox dosing resulted in a sharp decrease of sulfide, both in the air and in the bulk water, reaching maximum decreases of 98.7% and 94.7%, respectively. Quantitative molecular microbiology techniques indicated that the involved mechanism is the development of the nitrate-reducing, sulfide-oxidizing bacterium Thiomicrospira denitrificans instead of the direct inhibition of the SRB community. Denitrification rate in primary sedimentation tanks was enhanced by nitrate, being this almost completely consumed. No significant increase of inorganic nitrogen was found in the discharged effluent, thus reducing potential environmental hazards to receiving waters. This study demonstrates the effectiveness of nitrate addition in controlling sulfide generation at plant-scale, provides the mechanism and supports the environmental adequacy of this strategy.

The absence of suitable terminal electron acceptors (TEA) in soil might limit the oxidative metabolism of environmental microbial populations. Microbial electroremediating cells (MERCs) consist in a variety of bioelectrochemical devices that aim to overcome electron acceptor limitation and maximize metabolic oxidation with the purpose of enhancing the biodegradation of a pollutant in the environment. The objective of this work was to use MERCs principles for stimulating soil bacteria to achieve the complete biodegradation of the herbicide (14) C-isoproturon (IPU) to (14) CO(2) in soils. Our study concludes that using electrodes at a positive potential [+600 mV (versus Ag/AgCl)] enhanced the mineralization by 20-fold respect the electrode-free control. We also report an overall profile of the (14) C-IPU metabolites and a (14) C mass balance in response to the different treatments. The remarkable impact of electrodes on the microbial activity of natural communities suggests a promising future for this emerging environmental technology that we propose to name bioelectroventing. © 2016 The Authors.

2018-05-04

In recent years, barley has attracted more interest as a food and feed source because of its high soluble dietary fiber and β-glucan content compared with other small grains. Twenty-five barley genotypes (20 imported genotypes and five check cultivars) were grown in three environments for two successive seasons: 2015/2016 and 2016/2017. The first environment was in El-Nubaria, Alexandria, Egypt during 2015/2016, while the second and third environments were in El-Bostan, Elbhera, Egypt during 2015/2016 and 2016/2017. The experiments were conducted in a randomized complete block design with the three replicates. The primary objectives of the current study were to evaluate the performance of 20 imported barley genotypes under several environmental conditions. The imported materials were superior to the local commercial cultivars for several traits, including grain yield. Therefore, the superior genotypes will be further evaluated and used in barley breeding programs. Our future work will focus on creating several crosses among the selected superior genotypes to improve yield and other important traits, while applying marker-assisted selection.

USA-France: Confronting two perspectives on shale gas

Exploiting shale gas and oil can be seen from very different perspectives, whether you live in the US where it is a decade long reality shaping the country's energy landscape or in France, where it is banned by law since 2011. Beyond this situation, the overall legal framework that regulates (or not) environmental and water protection, the use of chemicals, land ownership and the exploitation of underground mineral resources, the attribution of licenses for exploration and exploitation, etc. in Europe (and particularly in France, the only European country with Bulgaria where hydraulic fracturation is strictly forbidden) and in the US is at complete variance. This presentation will discuss subsequent attitudes vis-à-vis exploration, exploitation, scientific research on shale gas and fracking, and public activism that has arisen as a result of environmental, socioeconomic and human concerns. It will compare and contrast the different views and look at lessons that can be learned from those differences. This work is building upon the experience of the authors who have studied the issues relating to energy, water, population and climate and their connections, as seen from both sides of the Atlantic.

Environmental Criteria in the Spanish Public Works Procurement Process

2017-01-01

Green Public Procurement (GPP) is defined as a process of contracting products, services, and works with the least possible damage to the environment during their life cycle. In order to improve the knowledge about GPP, a study of the use of environmental tendering criteria in the Spanish public construction sector has been performed. The results of this study show that the use of environmental criteria in Spanish public sector construction procurement is low in comparison to a certain group of countries, known as “Green 7”, in the European Union. Environmental criteria is the fourth criterion in importance, but its weight in the global of the process is much lower than other criteria such as price, memory of the construction process and the delivery time. National administrations use environmental criteria more frequently because they have more resources and staff training about environmental issues. Environmental criteria are more used in the tendering of civil projects and works whose budget exceeds ten million euro due to the environmental impact of these kind and/or size of projects.

The US DOE has initiated a program for advanced turbine systems (ATS) that will serve industrial power generation markets. The ATS will provide ultra-high efficiency, environmental superiority, and cost competitiveness. The ATS will foster (1) early market penetration that enhances the global competitiveness of US industry, (2) public health benefits resulting from reduced exhaust gas emissions of target pollutants, (3) reduced cost of power used in the energy-intensive industrial marketplace and (4) the retention and expansion of the skilled US technology base required for the design, development and maintenance of state-of-the-art advanced turbine products. The Industrial ATS Development and Demonstrationmore » program is a multi-phased effort. Solar Turbines Incorporated (Solar) has participated in Phases 1 and 2 of the program. On September 14, 1995 Solar was awarded a Cooperative Agreement for Phases 3 and 4 of the program. Phase 3 of the work is separated into two subphases: Phase 3A entails Component Design and Development Phase 3B will involve Integrated Subsystem Testing. Phase 4 will cover Host Site Testing. Forecasts call for completion of the program within budget as originally estimated. Scheduled completion is forecasted to be approximately 3 years late to original plan. This delay has been intentionally planned in order to better match program tasks to the anticipated availability of DOE funds. To ensure the timely realization of DOE/Solar program goals, the development schedule for the smaller system (Mercury 50) and enabling technologies has been maintained, and commissioning of the field test unit is scheduled for May of 2000. As of the end of the reporting period work on the program is 22.80% complete based upon milestones completed.

The federal environmental review process under the National Environmental Policy Act of 1969 (NEPA) can be complex and time consuming. Currently, a geothermal developer may have to complete the NEPA process multiple times during the development of a geothermal project. One mechanism to reduce the timeframe of the federal environmental review process for activities that do not have a significant environmental impact is the use of Categorical Exclusions (CXs), which can exempt projects from having to complete an Environmental Assessment or Environmental Impact Statement. This study focuses primarily on the CX process and its applicability to geothermal exploration. In thismore » paper, we Provide generalized background information on CXs, including previous NEPA reports addressing CXs, the process for developing CXs, and the role of extraordinary circumstances; Examine the history of the Bureau of Land Management's (BLM) geothermal CXs;Compare current CXs for oil, gas, and geothermal energy; Describe bills proposing new statutory CXs; Examine the possibility of standardizing geothermal CXs across federal agencies; and Present analysis from the Geothermal NEPA Database and other sources on the potential for new geothermal exploration CXs. As part of this study, we reviewed Environmental Assessments (EAs) conducted in response to 20 geothermal exploration drilling permit applications (Geothermal Drilling Permits or Notices of Intents) since the year 2001, the majority of which are from the last 5 years. All 20 EAs reviewed for this study resulted in a Finding of No Significant Impact (FONSI). While many of these FONSI's involved proponent proposed or federal agency required mitigation, this still suggests it may be appropriate to create or expand an exploration drilling CX for geothermal, which would have a significant impact on reducing geothermal exploration timelines and up-front costs. Ultimately, federal agencies tasked with permitting and completing environmental reviews for geothermal exploration drilling activities and/or legislative representatives are the responsible parties to discuss the merits and implementation of new or revised CXs for geothermal development.« less

To recover from work stress, a worksite health program aimed at improving physical activity and relaxation may be valuable. However, not every program is effective for all participants, as would be expected within a "one size fits all" approach. The effectiveness of how the program is delivered may differ across individuals. The aim of this study was to identify subgroups for whom one intervention may be better suited than another by using a new method called QUalitative INteraction Trees (QUINT). Data were used from the "Be Active & Relax" study, in which 329 office workers participated. Two delivery modes of a worksite health program were given, a social environmental intervention (group motivational interviewing delivered by team leaders) and a physical environmental intervention (environmental modifications). The main outcome was change in Need for Recovery (NFR) from baseline to 12 month follow-up. The QUINT method was used to identify subgroups that benefitted more from either type of delivery mode, by incorporating moderator variables concerning sociodemographic, health, home, and work-related characteristics of the participants. The mean improvement in NFR of younger office workers in the social environmental intervention group was significantly higher than younger office workers who did not receive the social environmental intervention (10.52; 95 % CI: 4.12, 16.92). Furthermore, the mean improvement in NFR of older office workers in the social environmental intervention group was significantly lower than older office workers who did not receive the social environmental intervention ( -10.65; 95 % CI: -19.35, -1.96). The results for the physical environmental intervention indicated that the mean improvement in NFR of office workers (regardless of age) who worked fewer hours overtime was significantly higher when they had received the physical environmental intervention than when they had not received this type of intervention (7.40; 95 % CI: 0.99, 13.81). Finally, for office workers who worked more hours overtime there was no effect of the physical environmental intervention. The results suggest that a social environmental intervention might be more beneficial for younger workers, and a physical environmental intervention might be more beneficial for employees with a few hours overtime to reduce the NFR.

While many studies have reported that individual differences in personality traits are genetically influenced, the neurobiological bases mediating these influences have not yet been well characterized. To advance understanding concerning the pathway from genetic variation to personality, here we examined whether measures of heritable variation in neuroanatomical size in candidate regions (amygdala and medial orbitofrontal cortex) were associated with heritable effects on personality. A sample of 486 middle-aged (mean = 55 years) male twins (complete MZ pairs = 120; complete DZ pairs = 84) underwent structural brain scans and also completed measures of two core domains of personality: positive and negative emotionality. After adjusting for estimated intracranial volume, significant phenotypic (rp) and genetic (rg) correlations were observed between left amygdala volume and positive emotionality (rp = .16, p < .01; rg = .23, p < .05, respectively). In addition, after adjusting for mean cortical thickness, genetic and nonshared-environmental correlations (re) between left medial orbitofrontal cortex thickness and negative emotionality were also observed (rg = .34, p < .01; re = −.19, p < .05, respectively). These findings support a model positing that heritable bases of personality are, at least in part, mediated through individual differences in the size of brain structures, although further work is still required to confirm this causal interpretation.

Transcriptome Sequencing Reveals Wide Expression Reprogramming of Basal and Unknown Genes in Leptospira biflexa Biofilms

ABSTRACT The genus Leptospira is composed of pathogenic and saprophytic spirochetes. Pathogenic Leptospira is the etiological agent of leptospirosis, a globally spread neglected disease. A key ecological feature of some pathogenic species is their ability to survive both within and outside the host. For most leptospires, the ability to persist outside the host is associated with biofilm formation, a most important bacterial strategy to face and overcome hostile environmental conditions. The architecture and biochemistry of leptospiral biofilms are rather well understood; however, the genetic program underpinning biofilm formation remains mostly unknown. In this work, we used the saprophyte Leptospira biflexa as a model organism to assess over- and underrepresented transcripts during the biofilm state, using transcriptome sequencing (RNA-seq) technology. Our results showed that some basal biological processes like DNA replication and cell division are downregulated in the mature biofilm. Additionally, we identified significant expression reprogramming for genes involved in motility, sugar/lipid metabolism, and iron scavenging, as well as for outer membrane-encoding genes. A careful manual annotation process allowed us to assign molecular functions to many previously uncharacterized genes that are probably involved in biofilm metabolism. We also provided evidence for the presence of small regulatory RNAs in this species. Finally, coexpression networks were reconstructed to pinpoint functionally related gene clusters that may explain how biofilm maintenance is regulated. Beyond elucidating some genetic aspects of biofilm formation, this work reveals a number of pathways whose functional dissection may impact our understanding of leptospiral biology, in particular how these organisms adapt to environmental changes. IMPORTANCE In this work, we describe the first transcriptome based on RNA-seq technology focused on studying transcriptional changes associated with biofilm growth in a member of the genus Leptospira. As many pathogenic species of this genus can survive inside the host but also persist in environmental water, mostly forming biofilms, identifying the molecular basis of this capacity can impact the understanding of how leptospires are able to fulfill a complete life cycle that alternates between adaptation to the host and adaptation to hostile external environmental conditions. We identified several genes and regulatory networks that can be the kickoff for deepening understanding of the molecular mechanisms involving bacterial persistence via biofilm formation; understanding this is important for the future development of tools for controlling leptospirosis.

A careful manual annotation process allowed us to assign molecular functions to many previously uncharacterized genes that are probably involved in biofilm metabolism. We also provided evidence for the presence of small regulatory RNAs in this species. Finally, coexpression networks were reconstructed to pinpoint functionally related gene clusters that may explain how biofilm maintenance is regulated. Beyond elucidating some genetic aspects of biofilm formation, this work reveals a number of pathways whose functional dissection may impact our understanding of leptospiral biology, in particular how these organisms adapt to environmental changes. IMPORTANCE In this work, we describe the first transcriptome based on RNA-seq technology focused on studying transcriptional changes associated with biofilm growth in a member of the genus Leptospira. As many pathogenic species of this genus can survive inside the host but also persist in environmental water, mostly forming biofilms, identifying the molecular basis of this capacity can impact the understanding of how leptospires are able to fulfill a complete life cycle that alternates between adaptation to the host and adaptation to hostile external environmental conditions. We identified several genes and regulatory networks that can be the kickoff for deepening understanding of the molecular mechanisms involving bacterial persistence via biofilm formation; understanding this is important for the future development of tools for controlling leptospirosis.

Woods, R. R.; Schubert, F. H.; Hallick, T. M.

1975-01-01

A program to characterize a Breadboard of an Electrochemical Air Revitalization System (BEARS) was successfully completed. The BEARS is composed of three components: (1) a water vapor electrolysis module (WVEM) for O2 production and partial humidity control, (2) an electrochemical depolarized carbon dioxide concentrator module (EDCM) for CO2 control, and (3) a power-sharing controller, designed to utilize the power produced by the EDCM to partially offset the WVEM power requirements. It is concluded from the results of this work that the concept of electrochemical air revitalization with power-sharing is a viable solution to the problem of providing a localized topping force for O2 generation, CO2 removal and partial humidity control aboard manned spacecraft. Continued development of the EARS concept is recommended, applying the operational experience and limits identified during the BEARS program to testing of a one-man capacity system and toward the development of advanced system controls to optimize EARS operation for given interfaces and requirements. Successful completion of this development will produce timely technology necessary to plan future advanced environmental control and life support system programs and experiments.

The objective of this work was to investigate the resistance of three Indonesian wood species to termite attack. Samples from sengon (Falcataria moluccana), mangium (Acacia mangium), and pine (Pinus merkusii) were treated with polystyrene at loading levels of 26.0%, 8.6%, and 7.7%, respectively. Treated and untreated samples were exposed to environmental conditions in the field for 3 months. Untreated specimens of sengon, mangium, and pine had resistance ratings of 3.0, 4.6, and 2.4, respectively, based on a 10-point scale from 0 (no resistance) to 10 (complete or near-complete resistance). Corresponding resistance values of 7.8, 7.2, and 8.2 were determined for specimens treated with polystyrene. Overall weight loss values of 50.3%, 23.3%, and 66.4% were found for untreated sengon, mangium, and pine samples, respectively; for treated samples, the values were 7.6%, 14.4%, and 5.1%, respectively. Based on the findings in this study, overall resistance to termite attack was higher for treated samples compared to untreated samples.

Dutch Musculoskeletal Questionnaire: description and basic qualities.

PubMed

Hildebrandt, V H; Bongers, P M; van Dijk, F J; Kemper, H C; Dul, J

2001-10-10

A questionnaire ('Dutch Musculoskeletal Questionnaire', DMQ) for the analysis of musculoskeletal workload and associated potential hazardous working conditions as well as musculoskeletal symptoms in worker populations is described and its qualities are explored using a database of 1575 workers in various occupations who completed the questionnaire. The 63 questions on musculoskeletal workload and associated potentially hazardous working conditions can be categorized into seven indices (force, dynamic and static load, repetitive load, climatic factors, vibration and ergonomic environmental factors). Together with four separate questions on standing, sitting, walking and uncomfortable postures, the indices constitute a brief overview of the main findings on musculoskeletal workload and associated potentially hazardous working conditions. Homogeneity of the indices is satisfactory. The divergent validity of the indices is fair when compared with an index of psychosocial working conditions and discomfort during exposure to physical loads. Worker groups with contrasting musculoskeletal loads can be differentiated on the basis of the indices and other factors. With respect to the concurrent validity, it appears that most indices and factors show significant associations with low back and/or neck-shoulder symptoms. This questionnaire can be used as a simple and quick inventory for occupational health services to identify worker groups in which a more thorough ergonomic analysis is indicated.

Exposure science is a holistic concept without prejudice to exposure source. Traditionally, measurements aimed at mitigating environmental exposures have not included exposures in the workplace, instead considering such exposures to be an internal affair between workers and their employers. Similarly, occupational (or industrial) hygiene has not typically accounted for environmental contributions to poor health at work. Many persons spend a significant amount of their lifetime in the workplace, where they maybe exposed to more numerous chemicals at higher levels than elsewhere in their environment. In addition, workplace chemical exposures and other exogenous stressors may increase epigenetic and germline modifications that are passed on to future generations. We provide a brief history of the development of exposure science from its roots in the assessment of workplace exposures, including an appendix where we detail current resources for education and training in exposure science offered through occupational hygiene organizations. We describe existing successful collaborations between occupational and environmental practitioners in the field of exposure science, which may serve as a model for future interactions. Finally, we provide an integrated vision for the field of exposure science, emphasizing interagency collaboration, the need for complete exposure information in epidemiological studies, and the importance of integrating occupational, environmental, and residential assessments. Our goal is to encourage communication and spur additional collaboration between the fields of occupational and environmental exposure assessment. Providing a more comprehensive approach to exposure science is critical to the study of the "exposome", which conceptualizes the totality of exposures throughout a person's life, not only chemical, but also from diet, stress, drugs, infection, and so on, and the individual response.

Juvenile myopia progression, risk factors and interventions.

PubMed

Myrowitz, Elliott H

2012-07-01

The development and progression of early onset myopia is actively being investigated. While myopia is often considered a benign condition it should be considered a public health problem for its visual, quality of life, and economic consequences. Nearly half of the visually impaired population in the world has uncorrected refractive errors, with myopia a high percent of that group. Uncorrected visual acuity should be screened for and treated in order to improve academic performance, career opportunities and socio-economic status. Genetic and environmental factors contribute to the onset and progression of myopia. Twin studies have supported genetic factors and research continues to identify myopia genetic loci. While multiple myopia genetic loci have been identified establishing myopia as a common complex disorder, there is not yet a genetic model explaining myopia progression in populations. Environmental factors include near work, education levels, urban compared to rural location, and time spent outdoors. In this field of study where there continues to be etiology controversies, there is recent agreement that children who spend more time outdoors are less likely to become myopic. Worldwide population studies, some completed and some in progress, with a common protocol are gathering both genetic and environmental cohort data of great value. There have been rapid population changes in prevalence rates supporting an environmental influence. Interventions to prevent juvenile myopia progression include pharmacologic agents, glasses and contact lenses. Pharmacological interventions over 1-2 year trials have shown benefits. Peripheral vision defocus has been found to affect the emmetropization process and may be affected by wearing glasses or contacts. Accommodation accuracy also has been implicated in myopia progression. Further research will aim to assess both the role and interaction of environmental influences and genetic factors.

Adsorption processes in spacecraft environmental control and life support systems

DallBauman, L. A.; Finn, J. E.

1999-01-01

The environmental control and life support system on a spacecraft maintains a safe and comfortable environment in which the crew can live and work by supplying oxygen and water and by removing carbon dioxide, water vapor, and trace contaminants from cabin air. Although open-loop systems have been used successfully in the past for short-duration missions, the economics of current and future long-duration missions in space will make nearly complete recycling of air and water imperative. A variety of operations will be necessary to achieve the goal of nearly complete recycling. These include separation and reduction of carbon dioxide, removal of trace gas-phase contaminants, recovery and purification of humidity condensate, purification and polishing of wastewater streams, and others. Several of these can be performed totally or in part by adsorption processes. These processes are good candidates to perform separations and purifications in space due to their gravity independence, high reliability, relative high energy efficiency, design flexibility, technological maturity, and regenerative nature. For these reasons, adsorption has historically played a key role in life support on U.S. and Russian piloted spacecraft. Among the life support applications that can be achieved through use of adsorption technology are removal of trace contaminants and carbon dioxide from cabin air and recovery of potable water from waste streams. In each of these cases adsorption technology has been selected for use onboard the International Space Station. The requirements, science, and hardware for these applications are discussed. Human space exploration may eventually lead to construction of planetary habitats. These habitats may provide additional opportunities for use of adsorption processes, such as control of greenhouse gas composition, and may have different resources available to them, such as gases present in the planetary atmosphere. Separation and purification processes based on adsorption can be expected to continue to fulfill environmental control and life support needs on future missions.

Occupational asthma is the most frequently diagnosed occupational lung disease reported to the SWORD (Surveillance of Work-related and Occupational Respiratory Disease) scheme. However, diagnosing occupational asthma is not straightforward, and establishing a link with work may be difficult. This study was undertaken to determine the differences between patients with occupational asthma and those with non-occupational asthma which might help in their diagnosis. Information was collected using a self-completed questionnaire. Questionnaires were distributed to 30 subjects aged 18-65 years at each of two clinics--one for patients with occupational asthma and one for those with cryptogenic and environmental asthma. Replies were received from 26 patients with occupational asthma (87%) and 29 patients with non-occupational asthma (97%). The age of onset was significantly higher for those with occupational asthma (42.6 vs 20.7 years). Significantly more subjects with occupational asthma reported improvement on holiday, whereas no significant difference was found in the numbers reporting worsening of symptoms on work days. Those with occupational asthma were less likely to report seasonal variation in symptoms, exacerbation by allergies, pets and stress, or a family history of asthma. Subjects with occupational asthma were more likely to become unemployed (50% vs 3%). Recognition of some of these features in a patient's history may help in the difficult task of differentiating occupational from non-occupational asthma, potentially avoiding the need for exhaustive investigations in some patients. The high prevalence of holiday improvement among subjects with non-occupational asthma suggested that domestic or environmental allergies arising outside the workplace may have been making an important contribution to ongoing symptoms in these subjects.

Application of handheld devices to field research among underserved construction worker populations: a workplace health assessment pilot study.

2011-04-01

Novel low-cost approaches for conducting rapid health assessments and health promotion interventions among underserved worker groups are needed. Recruitment and participation of construction workers is particularly challenging due to their often transient periods of work at any one construction site, and their limited time during work to participate in such studies. In the present methodology report, we discuss the experience, advantages and disadvantages of using touch screen handheld devices for the collection of field data from a largely underserved worker population. In March 2010, a workplace-centered pilot study to examine the feasibility of using a handheld personal device for the rapid health assessment of construction workers in two South Florida Construction sites was undertaken. A 45-item survey instrument, including health-related questions on tobacco exposure, workplace safety practices, musculoskeletal disorders and health symptoms, was programmed onto Apple iPod Touch® devices. Language sensitive (English and Spanish) recruitment scripts, verbal consent forms, and survey questions were all preloaded onto the handheld devices. The experience (time to survey administration and capital cost) of the handheld administration method was recorded and compared to approaches available in the extant literature. Construction workers were very receptive to the recruitment, interview and assessment processes conducted through the handheld devices. Some workers even welcomed the opportunity to complete the questionnaire themselves using the touch screen handheld device. A list of advantages and disadvantages emerged from this experience that may be useful in the rapid health assessment of underserved populations working in a variety of environmental and occupational health settings. Handheld devices, which are relatively inexpensive, minimize survey response error, and allow for easy storage of data. These technological research modalities are useful in the collection and assessment of environmental and occupational research data.

Activities completed under Phases 3A and 4 addressed completion of the engineering, design and documentation of the Material Handling and Conditioning System such that final procurement of the remaining process assemblies can be completed and construction of a Limited Demonstration Project be initiated in the event DOE elects to proceed with the construction and demonstration testing of the MH/C Subsystem.« less

The impact of completing upper secondary education - a multi-state model for work, education and health in young men.

Completing upper secondary education is associated with higher work participation and less health-related absence from work. Although these outcomes are closely interrelated, most studies focus on single outcomes, using cross-sectional designs or short follow-up periods. As such, there is limited knowledge of the long-term outcomes, and how paths for completers and non-completers unfold over time. In this paper, we use multi-state models for time-to-event data to assess the long-term effects of completing upper secondary education on employment, tertiary education, sick leave, and disability pension over twelve and a half years for young men. Baseline covariates and twelve and a half years of follow-up data on employment, tertiary education, sick leave and disability pension were obtained from national registries for all males born in Norway between 1971 and 1976 (n =184951). The effects of completing upper secondary education (by age 23) were analysed in a multi-state framework, adjusting for both individual and family level confounders. All analyses were done separately for general studies and vocational tracks. Completers do better on a range of outcomes compared to non-completers, for both fields of upper secondary education, but effects of completion change over time. The largest changes are for tertiary education and work, with the probability of work increasing reciprocally to the probability of education. Vocational students are quicker to transfer to the labour market, but tend to have more unemployment, sick leave and disability, and the absolute effects of completion on these outcomes are largest for vocational tracks. However, the relative effects of completion are larger for general studies. Completing upper secondary education increases long-term work participation and lowers health-related absence for young men, but effects diminish over time. Studies that have used shorter follow-up periods could be overstating the negative effects of dropout on labour market participation. Multi-state models are well suited to analyse data on work, education and health-related absence, and can be useful in understanding the dynamic aspects of these outcomes.

Progressively safer, cheaper demolition of Fernald

2000-09-29

Fluor Fernald, Inc. has been progressively improving Decontamination and Dismantlement (D&D) at the Department of Energy's Fernald Environmental Management Project by applying new technologies and better methodologies to the work. Demolition issues existed in the past that necessitated new or improved solutions to maintain worker safety, protect the environment and accomplish the work in a cost effective manner. Lessons learned from D&D of 80 structures has led to a systematic approach, which can be implemented in various D&D arenas. When facility production was halted, hold-up material and process residues remained in the process piping and components. Over 500,000 pounds ofmore » material was removed by workers who completed the tasks two years ahead of schedule, $7 million under budget and with an excellent safety record. This success was the result of detailed planning and irdision of lessons learned as work progressed from facility to facility. Work sequences were developed that reduced airborne contamination. Demolition of structures has been performed at Fernald by carefully selected and qualified subcontractors. Asbestos and lead abatement, equipment, piping and conduit removal, and structural demolition have been completed to progressively higher performance specifications developed by Fluor Fernald based on lessons learned during execution. Safety continues to be the primary consideration in performing potentially hazardous work. Technologies such as hydraulic shears have been developed and used to keep workers away from danger. A new technology, ''Cool Suits,'' has been demonstrated to help prevent heat stress when anti-contamination clothing is required in elevated temperature working conditions. For tall structures, implosion technologies have been employed with progressively improved results, Several other new technologies have been evaluated by Fluor Fernald and applied by subcontractors. The improved technologies included the oxy-gas torch, which uses gasoline instead of acetylene gas, and a vacuum system for asbestos removal of wall insulation. These new methods proved effective and beneficial. Fluor Fernald has integrated demolition activities with waste disposal requirements to enhance overall efficiency. The relatively straight steel configurations required for recycling, and waste acceptance criteria that dictate waste sizes are typically included in the subcontract specifications The progressive improvements by Fluor Fernald have led to cost savings and schedule acceleration without increased risk to workers or the environment. When Fluor Fernald came to the site in 1992, the remediation baseline reflected a completion schedule of 2020 and a cost of $7.2 billion. The current projection is 2008 and $4.2 billion.« less

These areas are on the National Priorities List (NPL), and cleanup activities at both areas are conducted in accordance with the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), as amended. DOE and DA are conducting a joint remedial investigation (RI) and baseline risk assessment (BRA) as part of the remedial investigation/feasibility studymore » (RI/FS) for the groundwater operable units for the two areas. This joint effort will optimize further data collection and interpretation efforts and facilitate overall remedial decision making since the aquifer of concern is common to both areas. A Work Plan issued jointly in 1995 by DOE and the DA discusses the results of investigations completed at the time of preparation of the report. The investigations were necessary to provide an understanding of the groundwater system beneath the chemical plant area and the ordnance works area. The Work Plan also identifies additional data requirements for verification of the evaluation presented.« less

This study aimed to identify associations between sociodemographic, workplace, and school environmental factors and the occurrence of physical violence against teachers at school. This was a cross-sectional study of teachers that had been working for at least a year in elementary or middle schools in the state school system in Londrina, Paraná State, Brazil. A convenience sample was taken of the 20 schools with the most teachers in the city of Londrina. Data were obtained through interviews and self-completed questionnaires in 2012 and 2013. Physical violence was defined as reports of attempted or actual physical aggression using cold steel weapons or firearms in the 12 months prior to the study. Structural equation models were used for the data analysis. Of the 937 teachers eligible for the study, 789 (84.2%) were interviewed. The physical violence victimization rate in schoolteachers was 8.4%. Work conditions (number of schools where the teachers worked and type of employment contract) showed a direct effect on physical violence (p = 0.032), as did having experienced previous situations of violence in the school (p = 0.059). Age (up to 40 years) was indirectly related to physical violence, correlating with worse work conditions. The results highlight the importance of improving teachers' work conditions and implementing measures to prevent violence both in schools and in society as a whole.

The CERT Tribal Internship Program is part of the education and training opportunities provided by CERT to accelerate the development of American Indian technical professionals available to serve Tribes and expand the pool of these professionals. Tribes are severely impacted by the inadequate number of Indian professionals available to serve and facilitate Tribal participation and support of the energy future of Tribes,and subsequently the energy future of the nation. By providing interns with hands-on work experience in their field of study two goals are accomplished: (1) the intern is provided opportunities for professional enhancement; and (2) The pool of Indianmore » professionals available to meet the needs of Tribal government and Tribal communities in general is increased. As of January 17, 2003, Lance M Wyatt successfully completed his internship with the Interagency Working Group on Environmental Justice on the Task Force that specifically focuses their work on Tribal nations. While working as an intern with the National Transportation Program, Albuquerque operations, Jacqueline Agnew received an offer to work for the Alaska Native Health Board in Anchorage, Alaska. This was an opportunity that Ms. Agnew did not feel she could afford to forego and she left her internship position in February 2003. At present, CERT is in the process of finding another qualified individual to replace the internship position vacated by Ms. Agnew. Mr. Wyatt's and Ms. Agnew's final comments are given.« less

The Evolution of Successful Satellite Science to Air Quality Application Projects: From Inception to Realization

2012-12-01

Teams of scientist have been working for almost a decade with state, local, regional and federal Air Quality regulators and scientists on several projects that have been focused on improving biomass burning emissions within our nation's National Emissions Inventory (NEI). Initially, the NEI was based strictly on ground-based information that often used data aggregated from previous years reported at the county-centroid and completely ignored the spatial domain of all fires. This methodology resulted in gross inaccuracies; however it was an ingrained system and the users and organizations were largely comfortable. Improvements were viewed as too costly. Our task was to convince regulators, managers and users of the value that could be added by using satellite data to enhance the NEI. Certainly, there were individuals that understood the value of using satellite data, but they needed support to convince the establishment of the intrinsic, cost-effective value of publically-available satellite data. It was essential to present arguments, as well as requested verification and validation statistics, in the format that most suited the objectives of application organizations. This process incorporated: knowledge of state-of-the-art satellite data, algorithms and science; a working knowledge of the users applications and requirements; interacting with individuals with a variety of skill sets and goals; and perhaps most importantly, listening to the goals and responsibilities of the user community and fully communicating. Today, the Environmental Protection Agency and several state and regional organizations are using satellite data to estimate biomass burnings emissions at daily and annual scales for a number of critical environmental management and policy activities including regulation setting and regional strategy development for attainment of the National Ambient Air Quality Standards (NAAQS). We continue to work at the local, state and federal levels to improve the biomass burning portion of our nation's NEI at the crossroads of the applications 'largest cost-effective unknowns and uncertainties' and the 'best-available science and data'. Here, we will present a diagram tree of the completed evolution of a successful project, which includes the basic science on which this development is based and the succession of the use of satellite data within the applications and user communities.

This article examines the effectiveness of three different forms of explicit control of adaptive automation under low- and high-stress conditions, operationalised by different levels of noise. In total, 60 participants were assigned to one of three types of automation design (free, prompted and forced choice). They were trained for 4 h on a highly automated simulation of a process control environment, called AutoCAMS. This was followed by a 4-h testing session under noise exposure and quiet conditions. Measures of performance, psychophysiology and subjective reactions were taken. The results showed that all three modes of explicit control of adaptive automation modes were able to attenuate the negative effects of noise. This was partly due to the fact that operators opted for higher levels of automation under noise. It also emerged that forced choice showed marginal advantages over the two other automation modes. Statement of Relevance: This work is relevant to the design of adaptive automation since it emphasises the need to consider the impact of work-related stressors during task completion. During the presence of stressors, different forms of operator support through automation may be required than under more favourable working conditions.

The Environmental Implementation Plan (EIP) is a dynamic long-range environmental-protection plan for SRS. The EIP communicates the current and future (five year) environmental plans from individual organizations and divisions as well as site environmental initiatives which are designed to protect the environment and meet or exceed compliance with changing environmental/ regulatory requirements. Communication with all site organizations is essential for making the site environmental planning process work. Demonstrating environmental excellence is a high priority embodied in DOE and WSRC policy. Because of your support and participation in the three EIP initiatives; Reflections, Sectional Revision, and Integrated Planning, improvements are beingmore » made to the EIP and SRS environmental protection programs. I appreciate the ``Partnership in Environmental Excellence`` formed by the environmental coordinators and professionals who work daily toward our goal of compliance and environmental excellence. I look forward to seeing continued success and improvement in our environmental protection programs through combined efforts of all site organizations to protect our employees, the public health, and the environment. Together, we will achieve our site vision for SRS to be the recognized model for Environmental Excellence in the DOE Nuclear Weapons Complex.« less

The effects of a workplace design and training intervention and the relationships between perceived satisfaction of office workplace design factors (layout and storage) and work performance measures (individual performance, group collaboration and effectiveness) were studied with 120 office workers using the Workplace Environment Questionnaire. Further, we examined whether environmental control had a direct effect on work performance, and then explored whether environmental control mediated or moderated the relationship between workplace design factors and work performance. Results showed a significant, positive impact of the intervention on environmental satisfaction for workstation layout. Satisfaction with workstation layout had a significant relationship with individual performance, group collaboration and effectiveness; and satisfaction with workstation storage had a significant relationship with individual performance and group collaboration. Environmental control had a direct impact on individual performance and group collaboration; whereas, the mediating and moderating effects of environmental control on the relationship between workplace design factors and outcome variables were not significant.
