    Williams, T D; Readman, G D; Owen, S F

    2009-04-01

    An improved knowledge and understanding of the fundamental biological requirements is needed for many of the species of fish held in captivity and, without this knowledge it is difficult to determine the optimal conditions for laboratory culture. The aim of this paper is to review the key issues concerning environmental enrichment for laboratory-held fish species and identify where improvements are required. It provides background information on environmental enrichment, describes enrichment techniques currently used in aquatic ecotoxicology studies, identifies potential restrictions in their use and discusses why more detailed and species-specific guidance is needed.

    Lee, Kang N.

    1999-01-01

    Plasma-sprayed mullite (3Al2O3 central dot 2SiO2) and mullite/yttria-stabilized-zirconia (YSZ) dual layer coatings have been developed to protect silicon-based ceramics from environmental attack. Mullite-based coating systems show excellent durability in air. However, in combustion environments, corrosive species such as molten salt or water vapor penetrate through cracks in the coating and attack the Si-based ceramics along the interface, Thus modification of the coating system for enhanced crack-resistance is necessary for long-term durability in combustion environments. Other key durability issues include interfacial contamination and coating/substrate bonding. Interfacial contamination leads to enhanced oxidation and interfacial pore formation, while weak coating/substrate bonding leads to rapid attack of the interface by corrosive species, both of which can cause premature failure of the coating. Interfacial contamination can be minimized by limiting impurities in coating and substrate materials. The interface may be modified to improve the coating/substrate bond.

    Background: In support of the Integrated Risk Information System (IRIS), the U.S. Environmental Protection Agency (EPA) has evaluated the human health hazards of biphenyl exposure. Objectives: We review key findings and scientific issues regarding expected human health effects of biphenyl. Methods: Scientific literature from 1926 through September 2012 was critically evaluated to identify potential human health hazards associated with biphenyl exposure. Key issues related to the carcinogenicity and noncancer health hazards of biphenyl were examined based on evidence from experimental animal bioassays and mechanistic studies. Discussion: Systematic consideration of experimental animal studies of oral biphenyl exposure took into account the variety of study designs (e.g., study sizes, exposure levels, and exposure durations) to reconcile differing reported results. The available mechanistic and toxicokinetic evidence supports the hypothesis that male rat urinary bladder tumors arise through urinary bladder calculi formation but is insufficient to hypothesize a mode of action for liver tumors in female mice. Biphenyl and its metabolites may induce genetic damage, but a role for genotoxicity in biphenyl-induced carcinogenicity has not been established. Conclusions: The available health effects data for biphenyl provides suggestive evidence for carcinogenicity in humans, based on increased incidences of male rat urinary bladder tumors at high exposure levels and on female mouse liver tumors. Kidney toxicity is also a potential human health hazard of biphenyl exposure. Citation: Li Z, Hogan KA, Cai C, Rieth S. 2016. Human health effects of biphenyl: key findings and scientific issues.

  12. Upstream/downstream: Issues in environmental ethics

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

    Scherer, D.

    1991-01-01

    Upstream/Downstream reminds us that there are four issues that are more or less distinctive to environmental ethics. First, and most distinctively, environmental issues involve the standing of nonhuman living things and systems. Thus, environmental politics is only partly a clash among the interest of the parties involved; it often involves actions on behalf of the existence rights of nonhuman life forms. Second, environmental ethics concern the intergenerational distribution of benefits more explicitly than do most other ethical issues, which brings out serious weaknesses in legal frameworks that rely on claims for damages. Third, the complexity and indirectness of many environmentalmore » impacts introduces a high degree of uncertainty and thus technical as well as ethical issues of prudent behavior. Specifically, where science may not fully reveal environmental risks, should development proceed; should analysis proceed if it is known to have a Pollyanna bias Fourth, insofar as environmental damage is typically done to common property, and thus its regulation is generally a matter for governmental regulation, the obligations of private actors to make sacrifices beyond what government requires is at issue - an issue that one would expect to be taken up at length in the other volumes.« less

    Murphy, E; King, E A

    2010-04-01

    This paper explores methodological issues and policy implications concerning the implementation of the EU Environmental Noise Directive (END) across Member States. Methodologically, the paper focuses on two key thematic issues relevant to the Directive: (1) calculation methods and (2) mapping methods. For (1), the paper focuses, in particular, on how differing calculation methods influence noise prediction results as well as the value of the EU noise indicator L(den) and its associated implications for comparability of noise data across EU states. With regard to (2), emphasis is placed on identifying the issues affecting strategic noise mapping, estimating population exposure, noise action planning and dissemination of noise mapping results to the general public. The implication of these issues for future environmental noise policy is also examined. Copyright (c) 2009 Elsevier Ltd. All rights reserved.

    2012-01-01

    Background: In support of the Integrated Risk Information System (IRIS), the U.S. Environmental Protection Agency (EPA) completed a toxicological review of trichloroethylene (TCE) in September 2011, which was the result of an effort spanning > 20 years. Objectives: We summarized the key findings and scientific issues regarding the human health effects of TCE in the U.S. EPA’s toxicological review. Methods: In this assessment we synthesized and characterized thousands of epidemiologic, experimental animal, and mechanistic studies, and addressed several key scientific issues through modeling of TCE toxicokinetics, meta-analyses of epidemiologic studies, and analyses of mechanistic data. Discussion: Toxicokinetic modeling aided in characterizing the toxicological role of the complex metabolism and multiple metabolites of TCE. Meta-analyses of the epidemiologic data strongly supported the conclusions that TCE causes kidney cancer in humans and that TCE may also cause liver cancer and non-Hodgkin lymphoma. Mechanistic analyses support a key role for mutagenicity in TCE-induced kidney carcinogenicity. Recent evidence from studies in both humans and experimental animals point to the involvement of TCE exposure in autoimmune disease and hypersensitivity. Recent avian and in vitro mechanistic studies provided biological plausibility that TCE plays a role in developmental cardiac toxicity, the subject of substantial debate due to mixed results from epidemiologic and rodent studies. Conclusions: TCE is carcinogenic to humans by all routes of exposure and poses a potential human health hazard for noncancer toxicity to the central nervous system, kidney, liver, immune system, male reproductive system, and the developing embryo/fetus.

    This overview will discuss a number of the issues posed by the challenge of international environmental health. The reasons that environmental problems occurring elsewhere in the world are of importance to occupational and environmental physicians in North America include the interconnectedness of the biosphere of our planet so that environmental alterations in one part of the globe can have an adverse outcome on our health and well-being; the often high levels of pollution and environmental degradation elsewhere provide an opportunity to determine and predict adverse consequences of environmental agents pertinent to protecting our own health; and, most importantly, our own ability to provide assistance in helping economic development occur in a setting of low risk of environmental pollution.

  4. EDITORIAL: Environmental justice: a critical issue for all environmental scientists everywhere

    NASA Astrophysics Data System (ADS)

    Stephens, Carolyn

    2007-10-01

    It is now commonly understood that much of the worldwide burden of environmental ill health falls disproportionately on poorer peoples [1,2]. There is also substantial evidence that much environmental damage internationally is the result of the actions of richer nations or richer groups within nations—with impacts on poorer nations and poorer groups within nations [1,3,4]. It is becoming clear also that poorer peoples internationally experience multiple environmental harms, and that these may have a cumulative effect. The world is becoming more urbanized, and cities are becoming the locus for many of the local issues of environmental damage and environmental harm [4,5]. But cities are also responsible for substantial international environmental damage: for example, it is increasingly evident that cities are one of the main generators of climate change, and that the actions of people in cities in the rich world are deeply linked to the well-being of the overall ecosystem and of people worldwide. Environmental justice is a concept that links the environmental health science documenting these harms, to debates around rights, justice and equity. It fundamentally deals with the distribution of environmental goods and harms—and looks at who bears those harms and who is responsible for creating those harms, in both a practical sense but also in terms of policy decisions. It is a radical environmental health movement that has evolved from civil society groups, angered at what they perceive as the `unjust' distribution of environmental resources for health and, conversely the `unjust' distribution of environmental harms. The movement now includes a collaboration of non-governmental organizations with environmental scientists, public health professionals, and lawyers, all working on the issue of the distributions of environmental harms and the rights of everyone to a healthy environment. This special issue is both timely and important. Environmental justice is moving

    In response to a joint request from the World Climate Research Program's Climate and Cryosphere Project, the International Arctic Science Committee, and the Arctic Council's Arctic Monitoring and Assessment Program an updated scientific assessment has been conducted of the Arctic Freshwater System (AFS), entitled the Arctic Freshwater Synthesis (AFSΣ). The major reason behind the joint request was an increasing concern that changes to the AFS have produced, and could produce even greater, changes to biogeophysical and socioeconomic systems of special importance to northern residents and also produce extra-Arctic climatic effects that will have global consequences. The AFSΣ was structured around six key thematic areas: atmosphere, oceans, terrestrial hydrology, terrestrial ecology, resources, and modeling, the review of each coauthored by an international group of scientists and published as separate manuscripts in this special issue of Journal of Geophysical Research-Biogeosciences. This AFSΣ summary manuscript reviews key issues that emerged during the conduct of the synthesis, especially those that are cross-thematic in nature, and identifies future research required to address such issues.

    2014-01-01

    Against the background of increasing awareness and appreciation of issues such as global warming and the impact of mankind’s activities such as agriculture on the global environment, this paper updates previous assessments of some key environmental impacts that crop biotechnology has had on global agriculture. It focuses on the environmental impacts associated with changes in pesticide use and greenhouse gas emissions arising from the use of GM crops. The adoption of the technology has reduced pesticide spraying by 503 million kg (-8.8%) and, as a result, decreased the environmental impact associated with herbicide and insecticide use on these crops (as measured by the indicator the Environmental Impact Quotient [EIQ]) by 18.7%. The technology has also facilitated a significant reduction in the release of greenhouse gas emissions from this cropping area, which, in 2012, was equivalent to removing 11.88 million cars from the roads.

    Environmental health problems in Malaysia are mostly attributed to atmospheric pollution, water pollution, climate change, ozone depletion, and solid waste management, as well as toxic, chemical, and hazardous waste management. The Ministry of Health, Malaysia, has been vigorously pursuing the environmental health agenda by collaborating with other agencies at district, state, national, and international levels. This article discusses the issues and management framework of environmental health in Malaysia. Some issues requiring further investigation in order to clearly understand the trade-off between atmospheric change and environmental health are suggested. These suggestions are developed with particular reference to appraisals concerned with the development and implementation of environmental policy, programs, and practice. Research on the relevant issues is discussed and a framework is built involving a comprehensive review of the literature and existing framework of Malaysian environmental health.

  9. A study on the impact of the GLOBE program on students' attitudes regarding environmental issues

    NASA Astrophysics Data System (ADS)

    Manfready, Gary Martin

    A key objective in environmental curricula should be to instill responsible and concerned attitudes toward environmental issues. This can be accomplished through the application of innovative programs which emphasize the development of the affective domain of learning. The development of personal attitudes is one form of evidence that the affective domain is being addressed. This study was undertaken to determine the impact of the GLOBE program (Global Learning and Observation to Benefit the Environment) on the attitudes of students toward environmental issues. Three hundred and five middle and high school level students from four states were surveyed to determine their attitudes toward selected environmental statements. Results demonstrated that attitudes toward environmental issues of GLOBE students were significantly greater than non-GLOBE students. Additional analysis demonstrated that regardless of grade levels, gender, racial and ethnicity backgrounds, depth of GLOBE involvement, and degree of teachers' GLOBE experiences, GLOBE students display similar levels of attitudes toward environmental issues. Establishment of a reliable Likert scale measurement instrument was accomplished. Permission to use an existing survey was obtained. Additional items were added to increase validity. Establishment of reliability was accomplished through a Guttman split half analysis of the piloted instrument. Through the use of factor analysis, four categories or sub-groupings of attitudes were determined to exist. Reliability was established for the factors. These sub-groupings were identified as personal commitment to environmental protection, awareness of avenues for action, loci of control, and students' perception of teachers' abilities to present environmental topics. These categories were a part of the analysis of four hypotheses.

    2011-01-01

    Considering the important issues concerning food, environment, and energy that humans are facing in the 21st century, humans mostly depend on plants. Unlike animals which move from an inappropriate environment, plants do not move, but rapidly sense diverse environmental changes or invasion by other organisms such as pathogens and insects in the place they root, and adapt themselves by changing their own bodies, through which they developed adaptability. Whole genetic information corresponding to the blueprints of many biological systems has recently been analyzed, and comparative genomic studies facilitated tracing strategies of each organism in their evolutional processes. Comparison of factors involved in intracellular signal transduction between animals and plants indicated diversification of different gene sets. Reversible binding of Ca2+ to sensor proteins play key roles as a molecular switch both in animals and plants. Molecular mechanisms for signaling network of environmental sensing and adaptation in plants will be discussed with special reference to Ca2+ as a key element in information processing.

  16. Attending to scalar ethical issues in emerging approaches to environmental health research and practice.

    PubMed

    Buse, Chris G; Smith, Maxwell; Silva, Diego S

    2018-06-04

    Accelerated changes to the planet have created novel spaces to re-imagine the boundaries and foci of environmental health research. Climate change, mass species extinction, ocean acidification, biogeochemical disturbance, and other emergent environmental issues have precipitated new population health perspectives, including, but not limited to, one health, ecohealth, and planetary health. These perspectives, while nuanced, all attempt to reconcile broad global challenges with localized health impacts by attending to the reciprocal relationships between the health of ecosystems, animals, and humans. While such innovation is to be encouraged, we argue that a more comprehensive engagement with the ethics of these emerging fields of inquiry will add value in terms of the significance and impact of associated interventions. In this contribution, we highlight how the concept of spatial and temporal scale can be usefully deployed to shed light on a variety of ethical issues common to emerging environmental health perspectives, and that the potential of scalar analysis implicit to van Potter's conceptualization of bioethics has yet to be fully appreciated. Specifically, we identify how scale interacts with key ethical issues that require consideration and clarification by one health, ecohealth, and planetary health researchers and practitioners to enhance the effectiveness of research and practice, including justice and governance.

    Environmental justice (EJ) research seeks to document and redress the disproportionate environmental burdens and benefits associated with social inequalities. Although its initial focus was on disparities in exposure to anthropogenic pollution, the scope of EJ research has expanded. In the context of intensifying social inequalities and environmental problems, there is a need to further strengthen the EJ research framework and diversify its application. This Special Issue of the International Journal of Environmental Research and Public Health (IJERPH) incorporates 19 articles that broaden EJ research by considering emerging topics such as energy, food, drinking water, flooding, sustainability, and gender dynamics, including issues in Canada, the UK, and Eastern Europe. Additionally, the articles contribute to three research themes: (1) documenting connections between unjust environmental exposures and health impacts by examining unsafe infrastructure, substance use, and children’s obesity and academic performance; (2) promoting and achieving EJ by implementing interventions to improve environmental knowledge and health, identifying avenues for sustainable community change, and incorporating EJ metrics in government programs; and (3) clarifying stakeholder perceptions of EJ issues to extend research beyond the documentation of unjust conditions and processes. Collectively, the articles highlight potentially compounding injustices and an array of approaches being employed to achieve EJ. PMID:27809294

    Chiu, Weihsueh A.; Caldwell, Jane C.; Keshava, Nagalakshmi; Scott, Cheryl Siegel

    2006-01-01

    Trichloroethylene (TCE) is a common environmental contaminant at hazardous waste sites and in ambient and indoor air. Assessing the human health risks of TCE is challenging because of its inherently complex metabolism and toxicity and the widely varying perspectives on a number of critical scientific issues. Because of this complexity, the U.S. Environmental Protection Agency (EPA) drew upon scientific input and expertise from a wide range of groups and individuals in developing its 2001 draft health risk assessment of TCE. This scientific outreach, which was aimed at engaging a diversity of perspectives rather than developing consensus, culminated in 2000 with 16 state-of-the-science articles published together as an Environmental Health Perspectives supplement. Since that time, a substantial amount of new scientific research has been published that is relevant to assessing TCE health risks. Moreover, a number of difficult or controversial scientific issues remain unresolved and are the subject of a scientific consultation with the National Academy of Sciences coordinated by the White House Office of Science and Technology Policy and co-sponsored by a number of federal agencies, including the U.S. EPA. The articles included in this mini-monograph provide a scientific update on the most prominent of these issues: the pharmacokinetics of TCE and its metabolites, mode(s) of action and effects of TCE metabolites, the role of peroxisome proliferator–activated receptor in TCE toxicity, and TCE cancer epidemiology.

    2003-01-01

    As part of the 2001 Census, the One Number Census project estimated and adjusted the Census database for underenumeration. As a result of the highly innovative One Number Census and the Quality Assurance process it encompassed, it was also ensured that robust results could be obtained for each local authority area. This article examines some of the issues and analyses that were undertaken as part of that assessment of the 2001 Census population counts for England and Wales. The article firstly highlights the key issues surrounding the implementation of the 2001 Census fieldwork. The article then explores the 2001 Census results through a series of demographic analyses to illustrate the sorts of issues investigated during the One Number Census Quality Assurance process itself. These analyses look at the patterns contained within the results, and comparisons with key alternative sources of population counts. Overall, these in-depth analyses and investigations provide further credence to the plausibility of the One Number Census results.

    To identify key issues affecting women general practitioners in their professional and non-professional lives. A qualitative study using the Delphi technique, with three rounds of data provision circulated to each participant. Coding was used to ensure anonymity. The participants were a purposive sample of 40 women GPs drawn from all Australian States and Territories. The study was conducted between October 1996 and January 1997. Key issues affecting the professional and non-professional lives of women GPs. Some of the key professional issues for women GPs were job satisfaction, balancing work and personal life, autonomy, availability of flexible and part-time work and training, affordability of professional expenses, fair remuneration, and having a voice in decision-making. Key non-professional issues included self-care; time for relationships with a partner, children, family and friends; and time management to allow pursuit of non-medical interests. The conflicting demands made on women GPs diminish their job satisfaction and lead to stress and imbalance in their lives. Recommendations to ameliorate the problems for women GPs include appropriate training, policy formation, financial and other support, and a change in cultural expectations of women GPs by the community, the profession and governments.

  9. NCAP projection displays: key issues for commercialization

    NASA Astrophysics Data System (ADS)

    Tomita, Akira; Jones, Philip J.

    1992-06-01

    Recently there has been much interest in a new polymer nematic dispersion technology, often called as NCAP, PDLC, PNLC, LCPC, etc., since projection displays using this technology have been shown to produce much brighter display images than projectors using conventional twisted nematic (TN) lightvalves. For commercializing projection displays based on this polymer nematic dispersion technology, the new materials must not only meet various electro- optic requirements, e.g., operational voltage, `off-state'' scattering angle, voltage holding ratio and hysteresis, but must also be stable over the lifetime of the product. This paper reports recent progress in the development of NCAP based projection displays and discusses some of the key commercialization issues.

    1980-01-01

    A critique of the weak empirical and theoretical foundations of commentaries on the mass media in the environmental literature argues that they stem from the incidental rather than fundamental concern for the social dimensions of environmental problems. The contributions of information theory, cybernetics, sociology, and political science to micro and macro theories of mass communications are reviewed. Information from empirical analyses of the mass media's portrayal of social issues, including the environment, is related to Hall's dominant ideology thesis of the mass media and the elitist-conflict model of society. It is argued that the media's portrayal of environmental issues ismore » structured by dominant power-holding groups in society with the result that the media effectively function to maintain and reinforce the status quo to the advantage of these dominant groups. 78 references.« less

  15. Prevention, communication and equity in environmental epidemiology: ethical issues.

    PubMed

    Pagliarani, Giovanna; Botti, Caterina

    2011-01-01

    In environmental epidemiology research, decisions about when and how to intervene requires adequate ethical reflection. In fact, different kinds of issues may arise about: research methods and knowledge production; management of the results in terms of their overall assessments or for the implementation of preventive actions; reclamation intervention. In this contribution we propose to consider three topics we regard as crucial to this ethical debate: the reporting of conclusive research data; the correct application of the precautionary principle; and the environmental equity issues.

  16. Climate patriots? Concern over climate change and other environmental issues in Australia.

    PubMed

    Tranter, Bruce; Lester, Libby

    2017-08-01

    Echoing the anti-pollution and resource conservation campaigns in the United States in the early-to-mid-twentieth century, some scholars advocate mobilising support for environmental issues by harnessing the notion of environmental patriotism. Taking action to reduce the impact of global warming has also been cast as a patriotic cause. Drawing upon quantitative data from a recent national survey, we examine the link between patriotism and environmental attitudes in Australia, focussing upon climate change. We find that patriotism has a largely neutral association with concern over environmental issues, with the exception of climate change and, to a lesser extent, wildlife preservation. Expressing concern over climate change appears to be unpatriotic for some Australians. Even after controlling for political party identification and other important correlates of environmental issue concerns, patriots are less likely than others to prioritise climate change as their most urgent environmental issue and less likely to believe that climate change is actually occurring.

  17. Hydrodynamics of coalbed methane reservoirs in the Black Warrior Basin: Key to understanding reservoir performance and environmental issues

    USGS Publications Warehouse

    Pashin, J.C.

    2007-01-01

    The Black Warrior Basin of the southeastern United States hosts one of the world's most prolific and long-lived coalbed methane plays, and the wealth of experience in this basin provides insight into the relationships among basin hydrology, production performance, and environmental issues. Along the southeast margin of the basin, meteoric recharge of reservoir coal beds exposed in an upturned fold limb exerts a strong control on water chemistry, reservoir pressure, and production performance. Fresh-water plumes containing Na-HCO3 waters with low TDS content extend from the structurally upturned basin margin into the interior of the basin. Northwest of the plumes, coal beds contain Na-Cl waters with moderate to high-TDS content. Carbon isotope data from produced gas and mineral cements suggest that the fresh-water plumes have been the site of significant bacterial activity and that the coalbed methane reservoirs contain a mixture of thermogenic and late-stage biogenic gases. Water produced from the fresh-water plumes may be disposed safely at the surface, whereas underground injection has been used locally to dispose of highly saline water. Wells in areas that had normal hydrostatic reservoir pressure prior to development tend to produce large volumes of water and may take up to 4 a to reach peak gas production. In contrast, wells drilled in naturally underpressured areas distal to the fresh-water plumes typically produce little water and achieve peak gas rates during the first year of production. Environmental debate has focused largely on issues associated with hydrologic communication between deep reservoir coal beds and shallow aquifers. In the coalbed methane fields of the Black Warrior Basin, a broad range of geologic evidence suggests that flow is effectively confined within coal and that the thick intervals of marine shale separating coal zones limit cross-formational flow. ?? 2007 Elsevier Ltd.

  18. Coalbed methane produced water in China: status and environmental issues.

    PubMed

    Meng, Yanjun; Tang, Dazhen; Xu, Hao; Li, Yong; Gao, Lijun

    2014-01-01

    As one of the unconventional natural gas family members, coalbed methane (CBM) receives great attention throughout the world. The major associated problem of CBM production is the management of produced water. In the USA, Canada, and Australia, much research has been done on the effects and management of coalbed methane produced water (CMPW). However, in China, the environmental effects of CMPW were overlooked. The quantity and the quality of CMPW both vary enormously between coal basins or stratigraphic units in China. The unit produced water volume of CBM wells in China ranges from 10 to 271,280 L/well/day, and the concentration of total dissolved solids (TDS) ranges from 691 to 93,898 mg/L. Most pH values of CMPW are more than 7.0, showing the alkaline feature, and the Na-HCO3 and Na-HCO3-Cl are typical types of CMPW in China. Treatment and utilization of CMPW in China lag far behind the USA and Australia, and CMPW is mainly managed by surface impoundments and evaporation. Currently, the core environmental issues associated with CMPW in China are that the potential environmental problems of CMPW have not been given enough attention, and relevant regulations as well as environmental impact assessment (EIA) guidelines for CMPW are still lacking. Other potential issues in China includes (1) water quality monitoring issues for CMPW with special components in special areas, (2) groundwater level decline issues associated with the dewatering process, and (3) potential environmental issues of groundwater pollution associated with hydraulic fracturing.

    Climate change and human activities are directly or indirectly influence the acceleration of environmental problems and natural hazards such as forest fires, drought and floods in the Asia-Pacific countries. Satellite technology has become one of the key information sources in assessment, monitoring and mitigation of these hazards and related phenomenon. However, there are still gaps between science and application of space technology in practical usage. Asia-Pacific Regional Space Agency Forum (APRSAF) recommended to initiate the Space Applications for Environment (SAFE) proposal providing opportunity to potential user agencies in the Asia Pacific region to develop prototype applications of space technology for number of key issues including forest resources management, coastal monitoring and management, agriculture and food security, water resource management and development user-friendly tools for application of space technology. The main activity of SAFE is SAFE prototyping. SAFE prototyping is a demonstration for end users and decision makers to apply space technology applications for solving environmental issues in Asia-Pacific region. By utilizing space technology and getting technical support by experts, prototype executers can develop the application system, which could support decision making activities. SAFE holds a workshop once a year. In the workshop, new prototypes are approved and the progress of on-going prototypes are confirmed. Every prototype is limited for two years period and all activities are operated by volunteer manner. As of 2016, 20 prototypes are completed and 6 prototypes are on-going. Some of the completed prototypes, for example drought monitoring in Indonesia were applied to operational use by a local official organization.

  12. A review on the key issues for lithium-ion battery management in electric vehicles

    NASA Astrophysics Data System (ADS)

    Lu, Languang; Han, Xuebing; Li, Jianqiu; Hua, Jianfeng; Ouyang, Minggao

    2013-03-01

    Compared with other commonly used batteries, lithium-ion batteries are featured by high energy density, high power density, long service life and environmental friendliness and thus have found wide application in the area of consumer electronics. However, lithium-ion batteries for vehicles have high capacity and large serial-parallel numbers, which, coupled with such problems as safety, durability, uniformity and cost, imposes limitations on the wide application of lithium-ion batteries in the vehicle. The narrow area in which lithium-ion batteries operate with safety and reliability necessitates the effective control and management of battery management system. This present paper, through the analysis of literature and in combination with our practical experience, gives a brief introduction to the composition of the battery management system (BMS) and its key issues such as battery cell voltage measurement, battery states estimation, battery uniformity and equalization, battery fault diagnosis and so on, in the hope of providing some inspirations to the design and research of the battery management system.

  14. Towards Providing Culturally Aware Nutritional Care for Transgender People: Key Issues and Considerations.

    PubMed

    Fergusson, Pamela; Greenspan, Nicole; Maitland, Lukas; Huberdeau, Rémy

    2018-06-01

    Transgender people are an important group for whom access to healthcare is often problematic. Dietitians need to be aware of key issues in transgender health to provide culturally competent clinical nutritional care. This article serves as a primer, clarifying key terms and concepts, exploring the impact of stigma and discrimination on health and nutrition for people from transgender communities, and offering practical advice for nutritional and other related issues. Education for dietitians both pre- and postqualification is an important part of improving care and building skills and awareness of cultural humility. Transgender people may be at increased nutritional risk due to increased risk of cardiovascular disease, HIV, body image issues, and food insecurity. This risk profile, along with the history of trauma both outside and related to the medical community means that there is an urgent need for dietitians to develop practice tools for assessment, care, and referral to improve the nutritional status and well-being of this client group.

  15. Environmental Durability Issues for Solar Power Systems in Low Earth Orbit

    NASA Technical Reports Server (NTRS)

    Degroh, Kim K.; Banks, Bruce A.; Smith, Daniela C.

    1994-01-01

    Space solar power systems for use in the low Earth orbit (LEO) environment experience a variety of harsh environmental conditions. Materials used for solar power generation in LEO need to be durable to environmental threats such as atomic oxygen, ultraviolet (UV) radiation, thermal cycling, and micrometeoroid and debris impact. Another threat to LEO solar power performance is due to contamination from other spacecraft components. This paper gives an overview of these LEO environmental issues as they relate to space solar power system materials. Issues addressed include atomic oxygen erosion of organic materials, atomic oxygen undercutting of protective coatings, UV darkening of ceramics, UV embrittlement of Teflon, effects of thermal cycling on organic composites, and contamination due to silicone and organic materials. Specific examples of samples from the Long Duration Exposure Facility (LDEF) and materials returned from the first servicing mission of the Hubble Space Telescope (HST) are presented. Issues concerning ground laboratory facilities which simulate the LEO environment are discussed along with ground-to-space correlation issues.

    Henriksen, Lasse Folke; Seabrooke, Leonard

    2016-09-01

    An ongoing question for institutional theory is how organizing occurs transnationally, where institution building occurs in a highly ambiguous environment. This article suggests that at the core of transnational organizing is competition and coordination within professional and organizational networks over who controls issues. Transnational issues are commonly organized through professional battles over how issues are treated and what tasks are involved. These professional struggles are often more important than what organization has a formal mandate over an issue. We highlight how 'issue professionals' operate in two-level professional and organizational networks to control issues. This two-level network provides the context for action in which professionals do their institutional work. The two-level network carries information about professional incentives and also norms about how issues should be treated and governed by organizations. Using network and career sequences methods, we provide a case of transnational organizing through professionals who attempt issue control and network management on transnational environmental sustainability certification. The article questions how transnational organizing happens, and how we can best identify attempts at issue control.

    2010-01-01

    Within Canadian Aboriginal communities, the process for utilizing environmental health research evidence in the development of policies and programs is not well understood. This fundamental qualitative descriptive study explored the perceptions of 28 environmental health researchers, senior external decision-makers and decision-makers working within Aboriginal communities about factors influencing knowledge transfer and exchange, beliefs about research evidence and Traditional Knowledge and the preferred communication channels for disseminating and receiving evidence. The results indicate that collaborative relationships between researchers and decision-makers, initiated early and maintained throughout a research project, promote both the efficient conduct of a study and increase the likelihood of knowledge transfer and exchange. Participants identified that empirical research findings and Traditional Knowledge are different and distinct types of evidence that should be equally valued and used where possible to provide a holistic understanding of environmental issues and support decisions in Aboriginal communities. To facilitate the dissemination of research findings within Aboriginal communities, participants described the elements required for successfully crafting key messages, locating and using credible messengers to deliver the messages, strategies for using cultural brokers and identifying the communication channels commonly used to disseminate and receive this type of information.

    2012-10-19

    Emergency planning in the UK has grown considerably in recent years, galvanised by the threat of terrorism. However, deficiencies in NHS emergency planning were identified and the evidence-base that underpins it is questionable. Inconsistencies in terminologies and concepts also exist. Different models of emergency management exist internationally but the optimal system is unknown. This study examines the evidence-base and evidence requirements for emergency planning in the UK health context. The study involved semi-structured interviews with key stakeholders and opinion leaders. Purposive sampling was used to obtain a breadth of views from various agencies involved in emergency planning and response. Interviews were then analysed using a grounded approach using standard framework analysis techniques. We conducted 17 key informant interviews. Interviewees identified greater gaps in operational than technical aspects of emergency planning. Social and behavioural knowledge gaps were highlighted with regards to how individuals and organisations deal with risk and behave in emergencies. Evidence-based approaches to public engagement and for developing community resilience to disasters are lacking. Other gaps included how knowledge was developed and used. Conflicting views with regards to the optimal configuration and operation of the emergency management system were voiced. Four thematic categories for future research emerged:(i) Knowledge-base for emergency management: Further exploration is needed of how knowledge is acquired, valued, disseminated, adopted and retained.(ii) Social and behavioural issues: Greater understanding of how individuals approach risk and behave in emergencies is required.(iii) Organisational issues in emergencies: Several conflicting organisational issues were identified; value of planning versus plans, flexible versus standardized procedures, top-down versus bottom-up engagement, generic versus specific planning, and reactive versus

    2010-07-01

    Progressive depletion of conventional fossil fuels with increasing energy consumption and greenhouse gas (GHG) emissions have led to a move towards renewable and sustainable energy sources. Lignocellulosic biomass is available in massive quantities and provides enormous potential for bioethanol production. However, to ascertain optimal biofuel strategies, it is necessary to take into account environmental impacts from cradle to grave. Life cycle assessment (LCA) techniques allow detailed analysis of material and energy fluxes on regional and global scales. This includes indirect inputs to the production process and associated wastes and emissions, and the downstream fate of products in the future. At the same time if not used properly, LCA can lead to incorrect and inappropriate actions on the part of industry and/or policy makers. This paper aims to list key issues for quantifying the use of resources and releases to the environment associated with the entire life cycle of lignocellulosic bioethanol production.

    1987-01-01

    Robotics has become a key technology consideration for the Space Station project to enable enhanced crew productivity and to maximize safety. There are many robotic functions currently being studied, including Space Station assembly, repair, and maintenance as well as satellite refurbishment, repair, and retrieval. Another area of concern is that of providing ground based experimenters with a natural interface that they might directly interact with their hardware onboard the Space Station or ancillary spacecraft. The state of the technology is such that the above functions are feasible; however, considerable development work is required for operation in this gravity-free vacuum environment. Furthermore, a program plan is evolving within NASA that will capitalize on recent government, university, and industrial robotics research and development (R and D) accomplishments. A brief summary is presented of the primary technology issues and physical examples are provided of the state of the technology for the initial operational capability (IOC) system as well as for the eventual final operational capability (FOC) Space Station.

    Application for contestable government-research funding and ethical approval requires researchers to outline how their intended research project contributes to Maori development or advancement. When formulating their research proposals, the key issues for researchers are research utility, defining Maori, informed consent, confidentiality, issues with human tissues and genetic material, participant remuneration and recognition (koha), intellectual property, and involvement of local Maori health or social services. The most common Maori responsiveness issues in research applications can be readily approached by researchers who address straightforward methodological concerns, by working through precedents established by peers and colleagues, as well as by working with end-users of their research.

    Priestly, Brian G; Di Marco, Peter; Sim, Malcolm; Moore, Michael R; Langley, Andrew

    2007-10-01

    Managing public concerns relating to chemical exposures can consume substantial public health resources, particularly as the scientific basis around these issues is often contentious. Toxicology remains underrecognized as a public health discipline in Australia, although Australian toxicologists are making significant contributions from academia, government, and the commercial sector toward assessing the level of risk and protecting the community from environmental hazards. Internationally, the growth of environmental toxicology and the promotion of sound science in risk assessment as a basis for making regulatory decisions have been, to some extent, driven by the outcomes of the 1992 UNCED Conference on Sustainable Development (Rio Summit) and its Chapter 19 Agenda 21 activities. The promotion of safe chemical management practices and the need for global strengthening of capabilities in toxicology are among the initiatives of the Intergovernmental Forum on Chemical Safety (IFCS), which was formed after the Rio Summit to manage these programs. This article describes some of the initiatives in capacity building that marked the development of environmental toxicology in Australia since 1992 in response to these international environmental health initiatives.

  5. Key Issues in the Modes of Action and Effects of Trichloroethylene Metabolites for Liver and Kidney Tumorigenesis

    PubMed Central

    Caldwell, Jane C.; Keshava, Nagalakshmi

    2006-01-01

    Trichloroethylene (TCE) exposure has been associated with increased risk of liver and kidney cancer in both laboratory animal and epidemiologic studies. The U.S. Environmental Protection Agency 2001 draft TCE risk assessment concluded that it is difficult to determine which TCE metabolites may be responsible for these effects, the key events involved in their modes of action (MOAs), and the relevance of these MOAs to humans. In this article, which is part of a mini-monograph on key issues in the health risk assessment of TCE, we present a review of recently published scientific literature examining the effects of TCE metabolites in the context of the preceding questions. Studies of the TCE metabolites dichloroacetic acid (DCA), trichloroacetic acid (TCA), and chloral hydrate suggest that both DCA and TCA are involved in TCE-induced liver tumorigenesis and that many DCA effects are consistent with conditions that increase the risk of liver cancer in humans. Studies of S-(1,2-dichlorovinyl)-l-cysteine have revealed a number of different possible cell signaling effects that may be related to kidney tumorigenesis at lower concentrations than those leading to cytotoxicity. Recent studies of trichloroethanol exploring an alternative hypothesis for kidney tumorigenesis have failed to establish the formation of formate as a key event for TCE-induced kidney tumors. Overall, although MOAs and key events for TCE-induced liver and kidney tumors have yet to be definitively established, these results support the likelihood that toxicity is due to multiple metabolites through several MOAs, none of which appear to be irrelevant to humans.

    PubMed Central

    Schlosser, Paul M.; Bale, Ambuja S.; Gibbons, Catherine F.; Wilkins, Amina

    2014-01-01

    Background: The U.S. EPA’s Integrated Risk Information System (IRIS) completed an updated toxicological review of dichloromethane in November 2011. Objectives: In this commentary we summarize key results and issues of this review, including exposure sources, identification of potential health effects, and updated physiologically based pharmacokinetic (PBPK) modeling. Methods: We performed a comprehensive review of primary research studies and evaluation of PBPK models. Discussion: Hepatotoxicity was observed in oral and inhalation exposure studies in several studies in animals; neurological effects were also identified as a potential area of concern. Dichloromethane was classified as likely to be carcinogenic in humans based primarily on evidence of carcinogenicity at two sites (liver and lung) in male and female B6C3F1 mice (inhalation exposure) and at one site (liver) in male B6C3F1 mice (drinking-water exposure). Recent epidemiologic studies of dichloromethane (seven studies of hematopoietic cancers published since 2000) provide additional data raising concerns about associations with non-Hodgkin lymphoma and multiple myeloma. Although there are gaps in the database for dichloromethane genotoxicity (i.e., DNA adduct formation and gene mutations in target tissues in vivo), the positive DNA damage assays correlated with tissue and/or species availability of functional glutathione S-transferase (GST) metabolic activity, the key activation pathway for dichloromethane-induced cancer. Innovations in the IRIS assessment include estimation of cancer risk specifically for a presumed sensitive genotype (GST-theta-1+/+), and PBPK modeling accounting for human physiological distributions based on the expected distribution for all individuals 6 months to 80 years of age. Conclusion: The 2011 IRIS assessment of dichloromethane provides insights into the toxicity of a commonly used solvent. Citation: Schlosser PM, Bale AS, Gibbons CF, Wilkins A, Cooper GS. 2015.

    2005-01-01

    The news media's potential to promote awareness of health issues is established, and media advocacy is now an important tool in combating tobacco use. This study examines newspaper editors' perspectives of tobacco-related issues. This study presents a textual analysis of tobacco-related editorials. The data consist of editorials on tobacco from a sample of 310 U.S. daily newspapers over the course of 1 year (2001). Data were sampled from a random one-third of the days per month, yielding 162 editorials for analysis. A qualitative textual analysis was conducted. Each editorial was coded for theme, position, and frame. We analyzed the topics gaining editorial attention and the arguments made to support various perspectives. Editorials discussed a variety of both positive and negative news events, largely conveying support for tobacco-control objectives. Various organizing frames were used-supporting policy interventions, condemning the industry, highlighting individual rights, and expressing general cynicism were most prevalent. Editors largely promoted tobacco-control efforts, particularly policy advances. There was, however, little coverage of key issues such as health effects and addiction-perhaps because they are no longer perceived to be contentious. Advocates should seek to address this area and minimize the cynicism of key media gatekeepers to avoid undermining policy and individual change efforts.

    Lee, Paul U.; Sheridan, Tom; Poage, james L.; Martin, Lynne Hazel; Jobe, Kimberly K.

    2010-01-01

    This report identifies key human-performance-related issues associated with Next Generation Air Transportation System (NextGen) research in the NASA NextGen-Airspace Project. Four Research Focus Areas (RFAs) in the NextGen-Airspace Project - namely Separation Assurance (SA), Airspace Super Density Operations (ASDO), Traffic Flow Management (TFM), and Dynamic Airspace Configuration (DAC) - were examined closely. In the course of the research, it was determined that the identified human performance issues needed to be analyzed in the context of NextGen operations rather than through basic human factors research. The main gaps in human factors research in NextGen were found in the need for accurate identification of key human-systems related issues within the context of specific NextGen concepts and better design of the operational requirements for those concepts. By focusing on human-system related issues for individual concepts, key human performance issues for the four RFAs were identified and described in this report. In addition, mixed equipage airspace with components of two RFAs were characterized to illustrate potential human performance issues that arise from the integration of multiple concepts.

    1997-05-01

    Central Europe has experienced environmental degradation for hundreds of years. The proximity of countries, their shared resources, and transboundary movement of environmental pollution, create the potential for regional environmental strife. The goal of this project was to identify the sources and sinks of environmental pollution in Central Europe and evaluate the possible impact of transboundary movement of pollution on the countries of Central Europe. In meeting the objectives of identifying sources of contaminants, determining transboundary movement of contaminants, and assessing socio-economic implications, large quantities of disparate data were examined. To facilitate use of the data, the authors refined mapping proceduresmore » that enable processing information from virtually any map or spreadsheet data that can be geo-referenced. Because the procedure is freed from a priori constraints of scale that confound most Geographical Information Systems, they have the capacity to generate new projections and apply sophisticated statistical analyses to the data. The analysis indicates substantial environmental problems. While transboundary pollution issues may spawn conflict among the Central European countries and their neighbors, it appears that common environmental problems facing the entire region have had the effect of bringing the countries together, even though opportunities for deteriorating relationships may still arise.« less

    2011-07-01

    Clinical trials are crucial to improve cancer treatment but recruitment is difficult. Optimised patient information has been recognised as a key issue. In line with the increasing focus on patients' perspectives in health care, we aimed to study patients' opinions about the written information used in three clinical trials for breast cancer. Primary data collection was done in focus group interviews with breast cancer patient advocates. Content analysis identified three major themes: comprehensibility, emotions and associations, and decision making. Based on the advocates' suggestions for improvements, 21 key issues were defined and validated through a questionnaire in an independent group of breast cancer patient advocates. Clear messages, emotionally neutral expressions, careful descriptions of side effects, clear comparisons between different treatment alternatives and information about the possibility to discontinue treatment were perceived as the most important issues. Patients' views of the information in clinical trials provide new insights and identify key issues to consider in optimising future written information and may improve recruitment to clinical cancer trials. © 2010 Blackwell Publishing Ltd.

  1. Reducing Environmental Allergic Triggers: Policy Issues.

    PubMed

    Abramson, Stuart L

    The implementation of policies to reduce environmental allergic triggers can be an important adjunct to optimal patient care for allergic rhinitis and allergic asthma. Policies at the local level in schools and other public as well as private buildings can make an impact on disease morbidity. Occupational exposures for allergens have not yet been met with the same rigorous policy standards applied for exposures to toxicants by Occupational Safety and Health Administration. Further benefit may be obtained through policies by local, county, state, and national governments, and possibly through international cooperative agreements. The reduction of allergenic exposures can and should be affected by policies with strong scientific, evidence-based derivation. However, a judicious application of the precautionary principle may be needed in circumstances where the health effect of inaction could lead to more serious threats to vulnerable populations with allergic disease. This commentary covers the scientific basis, current implementation, knowledge gaps, and pro/con views on policy issues in reducing environmental allergic triggers.

    1996-01-01

    Environmental health and environmental quality issues along the U.S.-Mexico border have been of concern for several years. The enactment of the North American Free Trade Agreement and the presence of the maquiladoras (foreign-owned industries using imported raw materials) have intensified those concerns recently. Efforts to assess these issues are complicated by the fact that many of the issues affecting the border region are within federal jurisdiction, but the problems are regional and local in nature. Thus, state and local governments become involved with public concerns about real and potential problems. One major problem is that environmental health data from this region are lacking, particularly from Mexico. Some new agencies such as the Border Environment Cooperation Commission, the United States-Mexico Border Health Commission, and the North American Commission on Environmental Cooperation have joined several existing agencies at the federal and state level to address environmental quality and health. Several studies have been initiated to determine air and water quality, but little is being done in the areas of hazardous waste and health assessment. Several problems are anticipated in the generation of such data, such as its format and accessibility. Data gaps and research needs are discussed. PMID:8793340

  9. A note on attitudes and knowledge concerning environmental issues in Sweden.

    PubMed

    Boman, Mattias; Mattsson, Leif

    2008-02-01

    As part of a larger research effort, the empirical basis for this note is responses to four out of many questions in a mailed survey, which primarily focused on national environmental objectives in Sweden. The results show that out of eight broad areas for use of tax money, five-including environment-are rated as important by over 90% of the respondents. Respondents appear to be less willing to discriminate between different issues covered by national environmental objectives, as all of these are rated as important by more than 80% of the respondents. The function of the ozone layer is an example of an environmental issue where the knowledge among people is relatively high, while this is not the case when it comes to the amount of pesticides used in agriculture. The results also show less support for actions at the individual level to improve the environment, as compared to support for actions taken by society at large through, e.g., technological improvement or policy intervention.

    Froyd, C. A.; Willis, K. J.

    2008-09-01

    The study of Quaternary environmental change is directly applicable to on-going issues of global conservation. Palaeoecological research techniques provide the tools to address some of the key questions presently being asked by conservation ecologists and land management organizations. But is this type of analysis currently being utilized to its full potential? Are the results of palaeoenvironmental analyses routinely applied to practical issues of natural resource management, and if not what can be done to expand the application of this research within the conservation community? This paper reviews recent developments in the application of the analysis of late Quaternary environmental change to key environmental issues of biodiversity and conservation management and examines areas which could be strengthened in the future including: (i) determination of baselines and natural ecosystem variability; (ii) understanding ecological thresholds and resilience; (iii) climate change conservation strategies; (iv) biological invasions; and (v) conservation and culture.

    2015-02-01

    Introducing new technologies into society raises considerable public concern. We determine the public concern about nanoparticles, and compare this concern to other environmental health issues such as wind farms and coal seam gas production. A repeat cross sectional survey examining views on environmental health issues, risk, chemicals and trust was undertaken in more than 1,300 Australian residents in 2000 and 2013. Logistic regression and principal component analysis was used to investigate predictors of nanoparticle concern and identify a component structure for environmental health issues that could explain a trend of future nanoparticle concern. Australians have a relatively low level of concern about the risks of nanoparticles to health when compared to their concerns about other environmental health issues. Items associated with concern included gender, a general wish to avoid chemicals and possibly trust in politicians. Concern over nanoparticles clustered with similar views on technological risks. Current public concern over the risks of nanoparticles is low. However, a reframing of the issue towards 'chemicals' is likely to have a negative effect on risk perceptions. This paper raises questions about appropriate channels for the effective communication of risk. © 2015 Public Health Association of Australia.

    1997-02-01

    New photovoltaic (PV) technologies promise low-cost, reliable PV modules and have the potential for significant PV penetration into the energy market. These prospects for commercialization have attracted renewed interest in the advantageous environmental impact of using PV and also in the potential environmental, health and safety (EHS) burdens in PV manufacturing and decommissioning. In this paper, we highlight recent studies on EHS issues: a) An integrated energy-environmental-economic analysis which shows that large-scale use of PV can significantly contribute to alleviating the greenhouse effect; in the United States alone, it could displace 450 million tons of carbon emissions by the year 2030, b) Recycling of the spent modules and scarp is economically feasible; current research centers on improving the efficiency and economics of recycling CdTe and CIS modules, c) Toxicological studies conducted by the National Institute of Environmental Health Sciences (NIEHS) compared the acute toxicity of CdTe, CIS, and CGS; CdTe was the most toxic, and CGS the least toxic of the three. Additional studies are now comparing the systemic toxicity of these compounds with the toxicity of their precursors.

    2013-01-01

    Pricing policies such as taxes and subsidies are important tools in preventing and controlling a range of threats to public health. This is particularly so in tobacco and alcohol control efforts and efforts to change dietary patterns and physical activity levels as a means of addressing increases in noncommunicable diseases. To understand the potential impact of pricing policies, it is critical to understand the nature of price elasticities for consumer products. For example, price elasticities are key parameters in models of any food tax or subsidy that aims to quantify health impacts and cost-effectiveness. We detail relevant terms and discuss key issues surrounding price elasticities to inform public health research and intervention studies. PMID:24028228

    2002-01-01

    Planetary exploration by astronauts will require extended periods of habitation on a planet's surface, under the influence of environmental factors that are different from those of Earth and the spacecraft that delivered the crew to the planet. Human exploration of Mars, a possible near-term planetary objective, can be considered a challenging scenario. Mission scenarios currently under consideration call for surface habitation periods of from 1 to 18 months on even the earliest expeditions. Methods: Environmental issues associated with Mars exploration have been investigated by NASA and the National Space Biomedical Research Institute (NSBRI) as part of the Bioastronautics Critical Path Roadmap Project (see http ://criticalpath.jsc.nasa.gov). Results: Arrival on Mars will immediately expose the crew to gravity only 38% of that at Earth's surface in possibly the first prolonged exposure to gravity other than the 1G of Earth's surface and the zero G of weightless space flight, with yet unknown effects on crew physiology. The radiation at Mars' surface is not well documented, although the planet's bulk and even its thin atmosphere may moderate the influx of galactic cosmic radiation and energetic protons from solar flares. Secondary radiation from activated components of the soil must also be considered. Ultrafine and larger respirable and nonrespirable particles in Martian dust introduced into the habitat after surface excursions may induce pulmonary inflammation exacerbated by the additive reactive and oxidizing nature of the dust. Stringent decontamination cannot eliminate mechanical and corrosive effects of the dust on pressure suits and exposed machinery. The biohazard potential of putative indigenous Martian microorganisms may be assessed by comparison with analog environments on Earth. Even in their absence, human microorganisms, if not properly controlled, can be a threat to the crew's health. Conclusions: Mars' surface offers a substantial challenge to the

  4. Incorporating Environmental and Sustainability Issues into the Curriculum in a Mineralogy Class

    NASA Astrophysics Data System (ADS)

    Cook, G. W.

    2013-12-01

    A traditional curriculum in mineralogy addresses classic subject matter such as crystal chemistry, crystallography, systematic mineralogy and optical mineralogy. This is entirely reasonable and appropriate, as these time-honored aspects of mineralogy are fundamental to students' understanding of Earth Materials; they are also important building blocks for an understanding of other geologic disciplines such as petrology, structural geology, and sedimentology. Due to the impressive breadth and amount of subject material that is covered in most mineralogy courses, time constraints do not allow instructors to branch out into more contemporary subjects. In our increasingly technologically-advanced (and crowded) modern society, issues pertaining to the environment and sustainability are at the forefront of scientific thought. In many introductory physical geoscience courses these issues are addressed and incorporated into the curriculum, thereby giving students valuable scientific background in modern environmental issues. However, in upper division classes (such as mineralogy) there is little time or motivation for instructors to add new content or to connect the course content with current environmental or societal concerns, even though there may be significant and meaningful opportunities to do so throughout the quarter or semester. Consequently, many students' understanding of environmental issues remains at an introductory or cursory level. In my mineralogy class at the University of California San Diego (UCSD), I teach a traditional curriculum with a modern approach that uses dynamic lectures, makes use of multimedia, and also utilizes current best teaching practices. As a department, we have recently made an increased effort to educate our students about environmental issues. Accordingly, I have integrated environmental and sustainability topics (when they are pertinent) into the curriculum as a regular component of the course. These topics typically relate to how

    The use of engineered nanomaterials (ENMs) for environmental remediation, known as nanoremediation, represents a challenging and innovative solution, ensuring a quick and efficient removal of pollutants from contaminated sites. Although the growing interest in nanotechnological solutions for pollution remediation, with significant economic investment worldwide, environmental and human risk assessment associated with the use of ENMs is still a matter of debate and nanoremediation is seen yet as an emerging technology. Innovative nanotechnologies applied to water and soil remediation suffer for a proper environmental impact scenario which is limiting the development of specific regulatory measures and the exploitation at European level. The present paper summarizes the findings from the workshop: "Ecofriendly Nanotechnology: state of the art, future perspectives and ecotoxicological evaluation of nanoremediation applied to contaminated sediments and soils" convened during the Biannual ECOtoxicology Meeting 2016 (BECOME) held in Livorno (Italy). Several topics have been discussed and, starting from current state of the art of nanoremediation, which represents a breakthrough in pollution control, the following recommendations have been proposed: (i) ecosafety has to be a priority feature of ENMs intended for nanoremediation; ii) predictive safety assessment of ENMs for environmental remediation is mandatory; (iii) greener, sustainable and innovative nano-structured materials should be further supported; (iii) those ENMs that meet the highest standards of environmental safety will support industrial competitiveness, innovation and sustainability. The workshop aims to favour environmental safety and industrial competitiveness by providing tools and modus operandi for the valorization of public and private investments.

    Fung, Chi-Hang Fred; Ma, Xiongfeng; Chau, H. F.

    2010-01-01

    Quantum key distribution (QKD) is a secure key generation method between two distant parties by wisely exploiting properties of quantum mechanics. In QKD, experimental measurement outcomes on quantum states are transformed by the two parties to a secret key. This transformation is composed of many logical steps (as guided by security proofs), which together will ultimately determine the length of the final secret key and its security. We detail the procedure for performing such classical postprocessing taking into account practical concerns (including the finite-size effect and authentication and encryption for classical communications). This procedure is directly applicable to realistic QKD experiments and thus serves as a recipe that specifies what postprocessing operations are needed and what the security level is for certain lengths of the keys. Our result is applicable to the BB84 protocol with a single or entangled photon source.

    Burek, Karey J.

    There is a divide between what students are being taught within the science classroom and what they experience out in the real world. This study sought to explore possible relationships between a socioscientific issues embedded curriculum and outcome variables addressing environmental attitude and knowledge, oral and written argumentation and critical thinking skills. Both quantitative and qualitative methods were used to examine both within and between class differences as well as individual differences between the beginning and end of a semester of elementary school. Results indicated that socioscientific issues assist students in developing their critical thinking skills while also providing students the opportunity to be exposed to and participate in local and global environmental issues influencing the community at large. Statistical significance was found between groups in regards to attitude toward the environment, the qualitative interviews did indicate that some students provided more advanced argumentation skills by articulating alternate viewpoints on controversial environmental topics. Theoretical implications regarding the use of socioscientific issues in the classroom are presented.

  16. Scaling up in international health: what are the key issues?

    PubMed

    Mangham, Lindsay J; Hanson, Kara

    2010-03-01

    The term 'scaling up' is now widely used in the international health literature, though it lacks an agreed definition. We review what is meant by scaling up in the context of changes in international health and development over the last decade. We argue that the notion of scaling up is primarily used to describe the ambition or process of expanding the coverage of health interventions, though the term has also referred to increasing the financial, human and capital resources required to expand coverage. We discuss four pertinent issues in scaling up the coverage of health interventions: the costs of scaling up coverage; constraints to scaling up; equity and quality concerns; and key service delivery issues when scaling up. We then review recent progress in scaling up the coverage of health interventions. This includes a considerable increase in the volume of aid, accompanied by numerous new health initiatives and financing mechanisms. There have also been improvements in health outcomes and some examples of successful large-scale programmes. Finally, we reflect on the importance of obtaining a better understanding of how to deliver priority health interventions at scale, the current emphasis on health system strengthening and the challenges of sustaining scaling up in the prevailing global economic environment.

    Art has the ability to convey serious environmental issues, inspiring people to respond personally Kim Abeles is an artist who crosses disciplines and media to explore and map urban and global environments. She has exhibited with a unique range of collaborators including smog control agencies, science and natural history museums, and educational and healthcare professionals. Her work has been exhibited across the world. Since 1985, her art projects have explored topics including air and water pollution, refuse and recycling, and consumption. This presentation will discuss three unconventional art projects from inspiration to impact including results. Most can be replicated in any educational or community setting to increase understanding of environmental issues. Abeles's Smog Collector series makes images from polluted air, helping viewers to see the air they breathe in an accessible, engaging, and visceral way. In addition to exhibitions of this work in art museums and galleries, it has been displayed in vehicle emissions testing booths to increase awareness and behavior change, and the process has been taught as curriculum in schools. Abeles sees consumption as a primary problem that leads to environmental decay. Her Paper Person was made from the California Science Center's paper trash that was generated on a single day by their visitors (Earth Day 2009). The 40' x 48' sculpture is in the permanent collection of the CSC, and the text accompanying the artwork prompts visitors to consider bringing their lunches next time instead of buying fast food. Similarly, Paper Person (Harvard Westlake School) is a figurative sculpture made of one week of students' paper trash. Exhibited in the school's gallery, students were able to identify their own scraps, and to see how their consumption and trash adds up. When the artwork was exhibited, the school decided to change the way they handled their lunch preparation, bottled water, and trash. gallery-of-solutions was a recent

  3. Impact of Environmental Issues on the High-Speed Civil Transport

    This paper provides an overview of the impact of environmental issues on the design and operation of the proposed High-Speed Civil Transport (HSCT). This proposal for a new generation commercial supersonic transport is being pursued by NASA and its US industry partners in the NASA High-Speed Research (HSR) Program. A second related paper describes the overall HSR Program, including a history of supersonic transport development that led to the present program, and a brief outline of the structure of the two-phase program and its management structure. The specific objectives are to address the four major barrier environmental issues and show their impact on the design of the airplane and potentially, its mode of operation. A brief historical perspective shows how HSR Phase I addressed these environmental topics and, with the successful completion of that program, led to the successful advocacy for the Phase II effort that followed. The Phase II program elements were discussed in the earlier paper and addressed technology programs to enhance the economic viability of the HSCT. Since many of the regulations that may effect the certification and operation of the HSCT are either not in place or well documented, a brief treatise is provided to address the status of the rules and the potential impact on the viability of the HSCT.

    2018-01-01

    Cass R. Sunstein's book The Ethics of Influence appears to have three ideological features notable for purposes of this essay. The book emphasizes choice architecture (and related notions such as nudges and defaults), which should be ethically scrutinized to guard against ethical abuses and to assist us in ethically desirable uses of scientific psychology and behavioral economics. (1) This particular book focuses more on scrutinizing nation-state government than on corporate activities. (2) This book focuses more on domestically directed governmental action than on externally directed governmental action. (3) This book focuses more on certain developed liberal democracies than on the more comprehensive global situation. Sunstein is especially interested in environmental issues, particularly energy policy, global warming, and climate change. This essay argues that Sunstein's conceptual scheme can be fruitfully expanded to progress toward a normative environmental ethics that can be integrated with the insights of global political economy.

    Throughout the western mountainous regions, wildfire risks are elevated due to both fire suppression activities which have changed the forest structure making it more susceptible to stand-killing fires and the expansion of human structures (houses, light commercial) into these same forests, By providing a market for currently noncommercial but flammable materials (small trees, tops, and branches), new and existing bioenergy industries could be a key factor in reducing the regional forest fuel loads. Although bioenergy would appear to be an ideal answer to the problem in many ways, the situation is complicated and numerous issues need resolution. A public fearfulmore » of logging in these regions needs assurance that harvesting for bioenergy is an environmentally and socially responsible solution to the current fuel build up in these forests.

    2015-08-01

    The aim of this study was to explore nurses' perceptions of climate and environmental issues and examine how nurses perceive their role in contributing to the process of sustainable development. Climate change and its implications for human health represent an increasingly important issue for the healthcare sector. According to the International Council of Nurses Code of Ethics, nurses have a responsibility to be involved and support climate change mitigation and adaptation to protect human health. This is a descriptive, explorative qualitative study. Nurses (n = 18) were recruited from hospitals, primary care and emergency medical services; eight participated in semi-structured, in-depth individual interviews and 10 participated in two focus groups. Data were collected from April-October 2013 in Sweden; interviews were transcribed verbatim and analysed using content analysis. Two main themes were identified from the interviews: (i) an incongruence between climate and environmental issues and nurses' daily work; and (ii) public health work is regarded as a health co-benefit of climate change mitigation. While being green is not the primary task in a lifesaving, hectic and economically challenging context, nurses' perceived their profession as entailing responsibility, opportunities and a sense of individual commitment to influence the environment in a positive direction. This study argues there is a need for increased awareness of issues and methods that are crucial for the healthcare sector to respond to climate change. Efforts to develop interventions should explore how nurses should be able to contribute to the healthcare sector's preparedness for and contributions to sustainable development. © 2015 The Authors.

    2005-12-01

    Environmental variability contributes to both mass mortality and resilience in tropical coral reef communities. We assess variations in sea surface temperature (SST) and ocean color in the Florida Keys using satellite imagery, and provide insight into how this variability is associated with locations of resilient coral communities (those unaffected by or able to recover from major events). The project tests the hypothesis that areas with historically low environmental variability promote lower levels of coral reef resilience. Time series of SST from the Advanced Very High Resolution Radiometer (AVHRR) sensors and ocean color derived quantities (e.g., turbidity and chlorophyll) from the Sea-viewing Wide Field of View Sensor (SeaWiFS) are being constructed over the entire Florida Keys region for a period of twelve and nine years, respectively. These data will be compared with historical coral cover data derived from Landsat imagery (1984-2002). Improved understanding of the causes of coral reef decline or resilience will help protect and manage these natural treasures.

    2016-11-09

    Children are at increased vulnerability to many environmental contaminants compared to adults due to their unique behavior patterns, increased contaminant intake per body weight, and developing biological systems. Depending upon their age, young children may crawl on the floor and may practice increased hand to mouth activity that may increase their dose-intake of specific contaminants that accumulate in dust and other matrices. Children are also smaller in size than adults, resulting in a greater body burden for a given contaminant dose. Because children undergo rapid transitions through particular developmental stages they are also especially vulnerable during certain growth-related time windows. A Special Issue was organized focused on the latest findings in the field of children's environmental exposure for these reasons. This editorial introduces articles in this Special Issue and emphasizes their main findings in advancing the field. From the many articles submitted to this Special Issue from around the world, 23 were accepted and published. They focus on a variety of research areas such as children's activity patterns, improved risk assessment methods to estimate exposures, and exposures in various contexts and to various contaminants. The future health of a nation relies on protecting the children from adverse exposures and understanding the etiology of childhood diseases. The field of children's environmental exposures must consider improved and comprehensive research methods aimed at introducing mitigation strategies locally, nationally, and globally. We are happy to introduce a Special Issue focused on children's environmental exposure and children's health and hope that it contributes towards improved health of children.

    Hexabromocyclododecane (HBCDD), as one of the most widely used brominated flame retardants (BFRs), is of great concern globally because of its persistence in the environment and negative impacts on humans and animals. HBCDD has been mainly used in flame-retarded expanded (EPS) and extruded (XPS) polystyrene foams for insulation in the construction industry. Most of these products will become a part of the construction and demolition (C&D) waste at the end of their life cycle (30-50 years) which is typically disposed of into landfills or incineration. However, the recycling of this material takes quite a low share compared with landfill and incineration. Consequently, high environmental risks will exist in these disposal approaches due to the HBCDD in C&D waste. Currently, XPS or EPS products containing HBCDD in the construction industry have not reached the end of their life cycle in most countries. Relatively little attention has been paid to this emergency issue by either the government or public. Furthermore, C&D waste is most likely disposed of by direct dumping, simple stacking, or open burning in developing countries. Therefore, this paper highlights the global environmental risks of HBCDD from C&D waste. Areas of research for key problems of HBCDD contained in C&D waste are suggested to help control and finally eliminate the impact.

    2017-10-23

    Environmental scientists and engineers have been exploring research and monitoring applications of robotics, as well as exploring ways of integrating robotics into ecosystems to aid in responses to accelerating environmental, climatic, and biodiversity changes. These emerging applications of robots and other autonomous technologies present novel ethical and practical challenges. Yet, the critical applications of robots for environmental research, engineering, protection and remediation have received next to no attention in the ethics of robotics literature to date. This paper seeks to fill that void, and promote the study of environmental robotics. It provides key resources for further critical examination of the issues environmental robots present by explaining and differentiating the sorts of environmental robotics that exist to date and identifying unique conceptual, ethical, and practical issues they present.

    The ways in which humans affect and are affected by their environments have been studied from many different perspectives over the past decades. However, it was not until the 1970s that the discussion of the ethical relationship between humankind and the environment formalized as an academic discipline with the emergence of environmental ethics. A few decades later, environmental health emerged as a discipline focused on the assessment and regulation of environmental factors that affect living beings. Our goal here is to begin a discussion specifically about the impact of modern environmental change on biomedical and social understandings of brain and mental health, and to align this with ethical considerations. We refer to this focus as Environmental Neuroethics, offer a case study to illustrate key themes and issues, and conclude by offering a five-tier framework as a starting point of analysis.

    The purpose of the study was to examine the effects of technology-infused issue investigations on high school students' environmental and ocean literacies. This study explored the effects of a new educational enrichment program termed Connecting the Ocean, Reefs, Aquariums, Literacy, and Stewardship (CORALS) on high school science students. The study utilized a mixed methods approach combining a quantitative quasi-experimental pre-post test design with qualitative case studies. The CORALS program is a new educational program that combines materials based on the Investigating and Evaluating Environmental Issues and Actions (IEEIA) curriculum program with the digital storytelling process. Over an 18-week period four high school science teachers and their approximately 169 students investigated environmental issues impacting coral reefs through the IEEIA framework. An additional approximately 224 students, taught by the same teachers, were the control group exposed to standard curriculum. Students' environmental literacy was measured through the Secondary School Environmental Literacy Instrument (SSELI) and students' ocean literacy was measured through the Students' Ocean Literacy Viewpoints and Engagement (SOLVE) instrument. Two classrooms were selected as case studies and examined through classroom observations and student and teacher interviews. The results indicated the CORALS program increased the knowledge of ecological principles, knowledge of environmental problems/issues, and environmental attitudes components of environmental literacy for the experimental group students. For ocean literacy, the experimental group students' scores increased for knowledge of ocean literacy principles, ability to identify oceanic environmental problems, and attitudes concerning the ocean. The SSELI measure of Responsible Environmental Behaviors (REB) was found to be significant for the interaction of teacher and class type (experimental or control). The students for Teachers A

    2006-12-01

    Students seldom have an opportunity to explore the issues related to the environmental impact of contamination on water resources. With NSF support we have developed the prototype Plume Busters, in which students take on the role of an environmental consultant. The software consists of an interactive, Java application and accompanying HTML linked pages. Following a pipeline spill, the environmental consultant is hired by the pipeline owner to locate the resulting plume created by the spill and remediate the contaminated aquifer at minimum monetary and time cost. The contamination must be removed from the aquifer before it reaches the river and eventually a downstream public water supply. The application simulates movement of a plume from a pipeline break through a shallow alluvial aquifer towards the river upstream from a municipal water supply intake. To locate the plume, the student places observation wells on a gridded map of the study area and the simulation returns the contaminant concentrations at those locations on the appropriate sample dates. Once the plume is located, the student is able to site pumping and injection wells on the map for aquifer remediation using a simple pump-and-treat technique. The simulation then computes the movement of particles to the pumping wells and returns the cumulative mass removed by the production remediation well. Plume Busters also provides teachers with a means to initiate student exploration of a wide range of environmental issues, including (1) source-water assessment and ground-water and wellhead protection zones, (2) the impact of human activities and technology on the hydrosphere and the biosphere, (3) the role of technology in the resolution of environmental issues (4) legal, social, political, and economic implications of environmental issues, and (5) risk assessment resulting from human activities.

    2017-06-28

    This paper examines the issue of acid mine drainage in South Africa and environmental decision making processes that could be taken to mitigate the problem in the context of both conventional risk assessment and the precautionary principle. It is argued that conventional risk assessment protects the status quo and hence cannot be entirely relied upon as an effective tool to resolve environmental problems in the context of South Africa, a developing country with complex environmental health concerns. The complexity of the environmental issues is discussed from historical and political perspectives. An argument is subsequently made that the precautionary principle is an alternative tool, and its adoption can be used to empower local communities. This work, therefore, adds to new knowledge by problematising conventional risk assessment and proposing the framing of the acid mine drainage issues in a complex and contextual scenario of a developing country-South Africa.

    As the next generation of scientists enters the field of environmental health, it is imperative that they view their contributions in the context of global environmental stewardship. In this commentary, a group of international graduate students facilitated by three experienced environmental health scientists present their views on what they consider to be the global environmental health concerns of today. This group convened initially in October 2004 at an international health conference in Prague, Czech Republic. In this report we identify perceived environmental health concerns that exist around the world, with a focus on Central and Eastern Europe. Additionally, we address these perceived problems and offers some potential solutions. At the meeting, students were invited to participate in two panel discussions. One group of young international scientists identified several significant global environmental health concerns, including air pollution, occupational hazards, and risk factors that may exacerbate current environmental health issues. The second panel determined that communication, education, and regulation were the mechanisms for addressing current environmental challenges. In this commentary we expand on the views presented at the meeting and represent the concerns of young investigators from nine different countries. We provide ideas about and support the exchange of information between developed and developing countries on how to handle the environmental health challenges that face the world today.

    Non-random patterns in the functional structure of communities are often interpreted as evidence for different forces governing their assemblage. However, community assembly processes may act antagonistically, countering each other's signatures on the functional structure of communities, which may lead to spurious inferences on the underlying mechanisms. To illustrate this issue, we assessed the joint effects of environmental filtering and facilitative interactions on a key leaf functional trait (i.e. specific leaf area, SLA) in Mediterranean dwarf-shrub communities, using a two-scale sampling approach. Specifically, we analyzed differences in community-weighted mean SLA values (CWM-SLA) between communities (community-scale) and between guilds within communities (guild-scale, i.e. individuals sampled in understorey, overstorey and open-ground conditions) across contrasted soil environments and elevational gradients. We found that communities on harsh edaphic conditions (i.e. dolomite habitats) showed significantly lower CWM-SLA values than communities on more fertile habitats. In contrast, elevation was a poor predictor of differences in CWM-SLA between the communities. This suggests that environmental filtering may influence leaf trait variation along soil gradients irrespective of elevation. On the other hand, communities on dolomite habitats showed strong differences in CWM-SLA between understorey (higher CWM-SLA) and either open-ground and overstorey guilds (lower CWM-SLA), whereas communities on more fertile soils showed no differences between the guilds. The strong differences in CWM-SLA between understorey and non-understorey guilds in dolomite communities suggest that facilitative interactions may be particularly at stake under stressful edaphic conditions, thus partially mitigating the effect of environmental filtering (i.e. low SLA values) on communities growing in harsh soils.

    effective instrumentation and institutional support. Some environmental regulations have not succeeded as they do not match the technical requirements and economic reality of the country or region, or because they do not take the institutional capabilities of the society that has to implement them into consideration. For the survival and sustenance of the SMEs in the leather industry, it may be a viable alternative to carry out the tanning process in a decentralized fashion such that the raw to semi-finished process is carried out in the large scale sector while the semi-finished to finished process could either be reserved or open to competition as per the countries' requirements. But the issue of concern is whether it is fair that the raw to semi-finished tanning process, containing 70% of the pollution discharge should be undertaken by developing countries alone, especially if it is at the cost of their survival! However, the game analysed in the paper reveals that tanning units in developing countries would prefer to comply with the regulations and stay in the industry, the alternatives being to collude or to compete!

    2007-01-01

    Energy is the essential commodity that powers the expanding global economy. Starting in the 1950s, oil and natural gas became the main sources of primary energy for the rapidly increasing world population (Edwards, 1997). In 2003, petroleum was the source for 62.1% of global energy, and projections by energy information administration (EIA) indicate that oil and gas will continue their dominance, supplying 59.5% of global energy in 2030 (EIA, 2007). Unfortunately petroleum and coal consumption carry major detrimental environmental impacts that may be regional or global in scale, including air pollution, global climate change and oil spills. This special volume of Applied Geochemistry, devoted to “Environmental Issues Related to Oil and Gas Exploration and Production”, does not address these major impacts directly because air pollution and global climate change are issues related primarily to the burning of petroleum and coal, and major oil spills generally occur during ocean transport, such as the Exxon Valdez 1989 spill of 42,000 m3 (260,000 bbl) oil into Prince William Sound, Alaska.

    The significance of politics and power dynamics has long been recognised in environmental assessment (EA) research, but there has not been sustained attention to power, either theoretically or empirically. The aim of this special issue is to encourage the EA community to engage more consistently with the issue of power. The introduction represents a ground-clearing exercise intended to clarify the terms of the debate about power in the EA field, and to contribute to the development of a research agenda. Research trends in the field are outlined, and potential analytic and normative lines of inquiry are identified. The contributions tomore » this special issue represent contrasting conceptual and methodological approaches that navigate the analytical and normative terrain of power dynamics in EA. Together, they demonstrate that power cannot be removed from EA policy or practices, and is a necessary research focus for the development of the field. - Highlights: Black-Right-Pointing-Pointer Introduces the themed section on power Black-Right-Pointing-Pointer Provides an overview of the papers in the themed section Black-Right-Pointing-Pointer Identifies research trends and directions for future research.« less

    Due to the diversification efforts of energy sources, use of natural gas that was newly introduced into Turkish economy, has been growing rapidly. Turkey has large reserves of coal, particularly of lignite. The proven lignite reserves are 8.0 billion tons. The estimated total possible reserves are 30 billion tons. Turkey, with its young population and growing energy demand per person, its fast growing urbanization, and its economic development, has been one of the fast growing power markets of the world for the last two decades. It is expected that the demand for electric energy in Turkey will be 580 billion kWh by the year 2020. Turkey's electric energy demand is growing about 6-8% yearly due to fast economic growing. This paper deals with energy demand and consumption for environmental issues in Turkey.

  3. Integration of Environmental Issues in a Physics Course: 'Physics by Inquiry' High School Teachers' Integration Models and Challenges

    NASA Astrophysics Data System (ADS)

    Kimori, David Abiya

    As we approach the second quarter of the twenty-first century, one may predict that the environment will be among the dominant themes in the political and educational discourse. Over the past three decades, particular perspectives regarding the environment have begun to emerge: (i) realization by human beings that we not only live on earth and use its resources at an increasingly high rate but we also actually belong to the earth and the total ecology of all living systems, (ii) there are strong interactions among different components of the large and complex systems that make up our environment, and (iii) the rising human population and its impact on the environment is a great concern (Hughes & Mason, 2014). Studies have revealed that although the students do not have a deep understanding of environmental issues and lack environmental awareness and attitudes necessary for protecting the environment, they have great concern for the environment (Chapman & Sharma, 2001; Fien, Yencken, & Sykes, 2002). However, addressing environmental issues in the classroom and other disciplines has never been an easy job for teachers (Pennock & Bardwell, 1994; Edelson, 2007). Using multiple case studies, this study investigated how three purposefully selected physics teachers teaching a 'Physics by Inquiry' course integrated environmental topics and issues in their classroom. Particularly this study looked at what integration models and practices the three physics teachers employed in integrating environmental topics and issues in their classroom and what challenges the teachers faced while integrating environmental topics in their classrooms. Data collection methods including field notes taken from observations, teachers' interviews and a collection of artifacts and documents were used. The data were coded analyzed and organized into codes and categories guided by Fogarty (1991) models of curriculum integration and Ham and Sewing (1988) four categories of barriers to environmental

    2011-01-01

    This paper is a synthesis of research on recruitment and retention challenges for home support workers (HSWs) in Canada. Home support workers (HSWs) provide needed support with personal care and daily activities to older persons living in the community. Literature (peer reviewed, government, and non-government documents) published in the past decade was collected from systematic data base searches between January and September 2009, and yielded over 100 references relevant to home care human resources for older Canadians. Four key human resource issues affecting HSWs were identified: compensation, education and training, quality assurance, and working conditions. To increase the workforce and retain skilled employees, employers can tailor their marketing strategies to specific groups, make improvements in work environment, and learn about what workers value and what attracts them to home support work. Understanding these HR issues for HSWs will improve recruitment and retention strategies for this workforce by helping agencies to target their limited resources. Given the projected increase in demand for these workers, preparations need to begin now and consider long-term strategies involving multiple policy areas, such as health and social care, employment, education, and immigration.

  5. Key Issues in the Role of Peroxisome Proliferator–Activated Receptor Agonism and Cell Signaling in Trichloroethylene Toxicity

    2006-01-01

    Peroxisome proliferator–activated receptor α (PPARα) is thought to be involved in several different diseases, toxic responses, and receptor pathways. The U.S. Environmental Protection Agency 2001 draft trichloroethylene (TCE) risk assessment concluded that although PPAR may play a role in liver tumor induction, the role of its activation and the sequence of subsequent events important to tumorigenesis are not well defined, particularly because of uncertainties concerning the extraperoxisomal effects. In this article, which is part of a mini-monograph on key issues in the health risk assessment of TCE, we summarize some of the scientific literature published since that time on the effects and actions of PPARα that help inform and illustrate the key scientific questions relevant to TCE risk assessment. Recent analyses of the role of PPARα in gene expression changes caused by TCE and its metabolites provide only limited data for comparison with other PPARα agonists, particularly given the difficulties in interpreting results involving PPARα knockout mice. Moreover, the increase in data over the last 5 years from the broader literature on PPARα agonists presents a more complex array of extraperoxisomal effects and actions, suggesting the possibility that PPARα may be involved in modes of action (MOAs) not only for liver tumors but also for other effects of TCE and its metabolites. In summary, recent studies support the conclusion that determinations of the human relevance and susceptibility to PPARα-related MOA(s) of TCE-induced effects cannot rely on inferences regarding peroxisome proliferation per se and require a better understanding of the interplay of extraperoxisomal events after PPARα agonism.

    Marine wave and tidal energy technology could interact with marine resources in ways that are not well understood. As wave and tidal energy conversion projects are planned, tested, and deployed, a wide range of stakeholders will be engaged; these include developers, state and federal regulatory agencies, environmental groups, tribal governments, recreational and commercial fishermen, and local communities. Identifying stakeholders’ environmental concerns in the early stages of the industry’s development will help developers address and minimize potential environmental effects. Identifying important concerns will also assist with streamlining siting and associated permitting processes, which are considered key hurdles by the industry inmore » the U.S. today. In September 2008, RE Vision consulting, LLC was selected by the Department of Energy (DoE) to conduct a scenario-based evaluation of emerging hydrokinetic technologies. The purpose of this evaluation is to identify and characterize environmental impacts that are likely to occur, demonstrate a process for analyzing these impacts, identify the “key” environmental concerns for each scenario, identify areas of uncertainty, and describe studies that could address that uncertainty. This process is intended to provide an objective and transparent tool to assist in decision-making for siting and selection of technology for wave and tidal energy development. RE Vision worked with H. T. Harvey & Associates, to develop a framework for identifying key environmental concerns with marine renewable technology. This report describes the results of this study. This framework was applied to varying wave and tidal power conversion technologies, scales, and locations. The following wave and tidal energy scenarios were considered: 4 wave energy generation technologies 3 tidal energy generation technologies 3 sites: Humboldt coast, California (wave); Makapu’u Point, Oahu, Hawaii (wave); and the Tacoma Narrows, Washington

    These days family-friendliness is a key issue for the future of businesses. Investments in a family conscious personnel policy are considered as forward-looking decisions in companies. This happens against the background of a sustainable personnel policy in times of a decrease in the number of employable persons, an increasing shortage of skilled workers and an ageing workforce. Family-friendly working conditions are becoming a key factor in the competition for staff. When choosing an employer, family-friendliness has become a crucial topic. Employment participation and skills of women, especially of mothers, have greatly increased. To facilitate the realisation of their wish to return to paid employment, however, measures to reconcile work and family are required. Family-conscious measures have been proven to lead to higher employee productivity. Job satisfaction and motivation of employees and accumulation of human capital increase, absenteeism declines, the return of investment rises. Fields of activity for family-friendly measures in companies range from working arrangements, parental leave and re-entry programmes and various child care offers to services for families. In connection with the demographic development the demand for a better reconciliation of work and elder care should in future become ever more important, just as the upkeep of the occupational skills and working capacity of an ageing workforce. Family-friendliness has to become an integral part of corporate culture.

    Fertility preservation in the young cancer survivor is recognized as a key survivorship issue by the American Society of Clinical Oncology and the American Society of Reproductive Medicine. Thus, health-care providers should inform women about the effects of cancer therapy on fertility and should discuss the different fertility preservation options available. It is also recommended to refer women expeditiously to a fertility specialist in order to improve counseling. Women’s age, diagnosis, presence of male partner, time available, and preferences regarding use of donor sperm influence the selection of the appropriate fertility preservation option. Embryo and oocyte cryopreservation are the standard techniques used while ovarian tissue cryopreservation is new, yet promising. Despite the importance of fertility preservation for cancer survivors’ quality of life, there are still communication and financial barriers faced by women who wish to pursue fertility preservation.

  10. Environmental issues in operations management

    NASA Astrophysics Data System (ADS)

    Muthulingam, Suresh

    Adoption of sustainable operating practices is becoming an increasingly important issue for many organizations in the world today. In this dissertation, I use empirical methods to investigate factors that influence the adoption of sustainable practices and also identify issues that may hinder the adoption of such practices. I explore these issues in two diverse settings. In Chapter 1, I investigate the adoption and non-adoption of energy efficiency initiatives using a database of over 100,000 recommendations provided to more than 13,000 small and medium sized manufacturing firms. Even though the average payback across all recommendations is just over one year, many of these profitable opportunities are not implemented. Using a probit instrumental variable model, I identify four biases in the adoption of these recommendations. First, managers are myopic as they miss out on many profitable opportunities. Second, managers are more influenced by upfront costs than by net benefits when evaluating such initiatives. Third, adoption of a recommendation depends not only on its characteristics but also on the sequence in which the recommendations are presented. Adoption rates are higher for initiatives appearing early in a list of recommendations. Finally, adoption is not influenced by the number of options provided to decision makers. This contributes to the debate about whether or not choice overload occurs. We highlight decision biases previously unobserved in the Operations Management literature using field data rather than experimental data. We draw implications for enhancing adoption of energy efficiency initiatives and for other decision contexts where a collection of process improvement recommendations are made to firms. In Chapter 2, I examine the depth of adoption of the voluntary LEED (Leadership in Energy and Environmental Design) standards for green buildings. Depth of adoption refers to the extent to which the buildings adopt practices related to the standard

    1998-01-01

    This paper addresses the effects of availability and anchoring-and-adjustment on people's beliefs and values concerning environmental issues. The first three studies focus on lay people's perceptions of the causes of large scale environmental risks, the second series of three studies deals with how people value environmental goods and how much they are prepared to pay to mitigate environmental risks. In studies 1-3 we investigate the effects of availability and anchoring-and-adjustment on estimating the contribution of various factors to large scale environmental risks. Highly complex risks such as acid rain and global warming tend to be associated with multiple causes, and our results show that estimating the role of these causes is clearly affected by availability and anchoring-and-adjustment. Both have sizeable effects and persist over time. Moreover, corrective procedures only seem to have a limited effect. Availability and anchoring-and-adjustment not only play a role in judging the possible causes of risks; they also play a role in research attempting to assess the public's willingness to pay (WTP) to protect our environment. The outcomes of WTP surveys are often used as a tool to help policy decision making. In the second part of this article we present three studies on this issue. Results provide further evidence of the impact of the two heuristics on the outcomes of WTP research. Implications for research and practice are briefly discussed.

    Adaptive landscapes represent a mapping between genotype and fitness. Rugged adaptive landscapes contain two or more adaptive peaks: allele combinations with higher fitness than any of their neighbors in the genetic space. How do populations evolve on such rugged landscapes? Evolutionary biologists have struggled with this question since it was first introduced in the 1930s by Sewall Wright. Discoveries in the fields of genetics and biochemistry inspired various mathematical models of adaptive landscapes. The development of landscape models led to numerous theoretical studies analyzing evolution on rugged landscapes under different biological conditions. The large body of theoretical work suggests that adaptive landscapes are major determinants of the progress and outcome of evolutionary processes. Recent technological advances in molecular biology and microbiology allow experimenters to measure adaptive values of large sets of allele combinations and construct empirical adaptive landscapes for the first time. Such empirical landscapes have already been generated in bacteria, yeast, viruses, and fungi, and are contributing to new insights about evolution on adaptive landscapes. In this Key Issues Review we will: (i) introduce the concept of adaptive landscapes; (ii) review the major theoretical studies of evolution on rugged landscapes; (iii) review some of the recently obtained empirical adaptive landscapes; (iv) discuss recent mathematical and statistical analyses motivated by empirical adaptive landscapes, as well as provide the reader with instructions and source code to implement simulations of evolution on adaptive landscapes; and (v) discuss possible future directions for this exciting field.

    2014-01-01

    Schools of nursing are challenged to find clinical placements in public health settings. Use of simulation can address situations unique to public health, with attention to specific concerns, such as environmental health. Environmental health is an integral part of public health nursing and is a standard of professional practice. Current simulations focus on acute care situations, offering limited scenarios with a public health perspective and excluding environmental health. This study's simulation scenario was created to enhance nursing students' understanding of public health concepts within an environmental health context. Outcomes from the simulation include the need for integration of environmental issues in public health teaching. Students stated that this scenario provided a broader understanding of the environmental influences that can affect the client's and family's health. This scenario fills a void in simulation content, while providing an interactive teaching and learning strategy to help students to apply knowledge to practice. Copyright 2014, SLACK Incorporated.

    Environmental justice combines the social justice and the environmental movements. The very term environmental justice is often and inaccurately used interchangeably with environmental racism and environmental equity. Environmental racism refers to any policy, practice or directive, intentional or not, that differentially affects the environment of individuals, groups or communities based on their race. The concept of environmental equity holds that all populations should bear a proportionate share of environmental pollution and health risks. Environmental justice is a broader term that encompasses both these concepts and connotes the laws must be applied with fairness and impartiality.

    2013-04-01

    According to the Environmental Protection Agency, there are presently over half a million brownfields in the United States, but this number only includes sites for which an Environmental Site Assessment has been conducted. The actual number of brownfields is certainly into the millions and constitutes one of the major environmental issues confronting all communities today. Taught in part online for more than a decade in environmental science courses at over a dozen colleges, universities, and high schools in the United States, Brownfield Action (BA) is an interactive, web-based simulation that combines scientific expertise, constructivist education philosophy, and multimedia to advance the teaching of environmental science (Bower et al., 2011). In the online simulation and classroom, students form geotechnical consulting companies, conduct environmental site assessment investigations, and work collaboratively to solve a problem in environmental forensics. The BA model contains interdisciplinary scientific and social information that are integrated within a digital learning environment that encourages students to construct their knowledge as they learn by doing. As such, the approach improves the depth and coherence of students understanding of the course material. Like real-world environmental consultants, students are required to develop and apply expertise from a wide range of fields, including environmental science and engineering as well as journalism, medicine, public health, law, civics, economics, and business management. The overall objective is for students to gain an unprecedented appreciation of the complexity, ambiguity, and risk involved in any environmental issue or crisis.

  8. High-quality collection and disposal of WEEE: Environmental impacts and resultant issues.

    PubMed

    Baxter, John; Lyng, Kari-Anne; Askham, Cecilia; Hanssen, Ole Jørgen

    2016-11-01

    Life cycle assessment of the collection, transport and recycling of various types of waste electrical and electronic equipment (WEEE) in Norway shows that small amounts of critical materials (refrigerants, precious/trace metals) are vital for the overall environmental accounts of the value chains. High-quality recycling ensures that materials and energy are effectively recovered from WEEE. This recovery means that responsible waste handling confers net environmental benefits in terms of global warming potential (GWP), for all types of WEEE analysed. For refrigeration equipment, the potential reduction of GWP by high-quality recycling is so large as to be of national significance. For all waste types, the magnitude of the net benefit from recovering materials and energy exceeds the negative consequences of irresponsible disposal. One outcome of this may be widespread misunderstanding of the need for recycling. Furthermore, framing public communication on recycling in terms of avoiding negative consequences, as is essentially universal, may not convey an appropriate message. The issue is particularly important where the consumer regards products as relatively disposable and environmentally benign, and/or where the "null option" of retaining the product at end-of-life is especially prevalent. The paper highlights the implications of all these issues for policy-makers, waste collectors and recyclers, and consumers. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Understanding how to source agricultural raw materials sustainably is challenging in today’s globalized food system given the variety of issues to be considered and the multitude of suggested indicators for representing these issues. Furthermore, stakeholders in the global food system both impact these issues and are themselves vulnerable to these issues, an important duality that is often implied but not explicitly described. The attention given to these issues and conceptual frameworks varies greatly—depending largely on the stakeholder perspective—as does the set of indicators developed to measure them. To better structure these complex relationships and assess any gaps, we collate a comprehensive list of sustainability issues and a database of sustainability indicators to represent them. To assure a breadth of inclusion, the issues are pulled from the following three perspectives: major global sustainability assessments, sustainability communications from global food companies, and conceptual frameworks of sustainable livelihoods from academic publications. These terms are integrated across perspectives using a common vocabulary, classified by their relevance to impacts and vulnerabilities, and categorized into groups by economic, environmental, physical, human, social, and political characteristics. These issues are then associated with over 2,000 sustainability indicators gathered from existing sources. A gap analysis is then performed to determine if particular issues and issue groups are over or underrepresented. This process results in 44 “integrated” issues—24 impact issues and 36 vulnerability issues —that are composed of 318 “component” issues. The gap analysis shows that although every integrated issue is mentioned at least 40% of the time across perspectives, no issue is mentioned more than 70% of the time. A few issues infrequently mentioned across perspectives also have relatively few indicators available to fully represent them

    Reality shock is a critical representation of the gap between nursing education and clinical practice and it is important to explore the level of reality shock among nurses. However, there is no relevant instrument to assess the level of reality shock in South Korea. The purpose of this is to determine the validity and reliability of the Korean version of the Environmental Reality Shock-Related Issues and Concerns instrument. A cross-sectional study design was used in this study. The data collection was conducted in selected 15 hospitals in South Korea. A convenience sample of 216 newly graduated nurses participated in the study. The Korean version of the Environmental Reality Shock-Related Issues and Concerns instrument was developed through the forward-backward translation technique, and revision based on feedback from expert groups. The internal consistency reliability was assessed using Cronbach's alpha, and the construct validity was determined via exploratory and confirmatory factor analysis. The Korean version of the Environmental Reality Shock-Related Issues and Concerns has reliable internal consistency (Cronbach's alpha=0.91). Exploratory factor analysis revealed five factors including job, relationships, expectations, private life, and performance, which explained 61.92% of variance. The factor loadings ranged from 0.451 to 0.832. The five-factor structure was validated by confirmatory factor analysis (RMR<0.05, CFI>0.9). It was concluded that the Korean version of the Environmental Reality Shock-Related Issues and Concerns instrument has satisfactory construct validity and reliability to measure the reality shock of newly graduated nurses in South Korea.

    The aim of this study is to develop lesson plans and student worksheets based socio-scientific issues on pollution environmental topic for seventh-grade junior high school students. Environmental pollution topic split into several subtopics namely air pollution, water pollution and soil pollution. The composing of lesson plans were developed based on socio-scientific issues with five stages, namely (1) Motivate; (2) Challenge; (3) Collect scientific evidence; (4) Analyse the evidence; (5) Build knowledge and make connections; and (6) Use evidence. While student worksheets contain articles on socio-scientific issues, practice, and there are a few questions to determine students’ reasoning. The method that is used in this research is research and development (R & D method). Development model used in this study is a model of Plomp that consists of four stages, namely: (1) Initial Research; (2) Design; (3) Realization or Construction; (4) Testing, evaluation and revision; (5) Implementation, while the research was limited to the fourth stage. Lesson plans and student worksheets based on socio-scientific issues was validated through an expert validation. The result showed that lesson plans and student worksheets based socio-scientific issues on pollution theme have a very decent and be able to apply in science classroom.

    2017-11-01

    With the development of China's economy, the problem of environmental pollution has become increasingly more serious, affecting the sustained and healthy development of Chinese cities and the willingness of residents to invest in fixed assets. In this paper, a panel data set of 70 of China's key cities from 2003 to 2014 is used to study the effect of environmental pollution on home prices in China's key cities. In addition to the static panel data regression model, this paper uses the generalized method of moments (GMM) to control for the potential endogeneity and introduce the dynamics. To ensure the robustness of the research results, this paper uses four typical pollutants: per capita volume of SO 2 emissions, industrial soot (dust) emissions, industrial wastewater discharge, and industrial chemical oxygen demand discharge. The analysis shows that environmental pollution does have a negative impact on home prices, and the magnitude of this effect is dependent on the level of economic development. When GDP per capita increases, the size of the negative impact on home prices tends to reduce. Industrial soot (dust) has the greatest impact, and the impact of industrial wastewater is relatively small. It is also found that some other social and economic factors, including greening, public transport, citizen income, fiscal situation, loans, FDI, and population density, have positive effects on home prices, but the effect of employment on home prices is relatively weak.

    Zooplankton are of great importance in marine food webs, where they serve to link the phytoplankton and bacteria with higher trophic levels. Zooplankton are a diverse group containing molluscs, crustaceans, fish larvae and many other taxa. The sheer number of species and often minor morphological distinctions between species makes it challenging and exceptionally time consuming to identify the species composition of marine zooplankton samples. As a part of the Marine Biodiversity Observation Network (MBON) project, we have developed and groundtruthed an alternative, relatively time-efficient method for zooplankton identification using environmental DNA (eDNA). Samples were collected from Molasses reef, Looe Key, and Western Sambo along the Florida Keys from five bi-monthly cruises on board the RV Walton Smith. Samples were collected for environmental DNA (eDNA) by filtering 1 L of water on to a 0.22 µm filter and zooplankton samples were collected using nets with three mesh sizes (64μm, 200μm, and 500μm) to catch different size fractions. Half of zooplankton samples were fixed in 70% ethanol and half in 10% formalin, for DNA extraction and morphological identification, respectively. Individuals representing visually abundant taxa were picked into individual wells for PCR with universal 18S rRNA gene primers and subsequent sequencing to build a reference barcode database for zooplankton species commonly found in the study region. PCR and Illumina MiSeq next generation sequencing was applied to the eDNA extracted from the 0.22 μm filters and sequences were be compared to our local custom database as well as publicly available databases to determine zooplankton community composition. Finally, composition and diversity analyses were performed to compare results obtained with the new eDNA approach to standard morphological classification of zooplankton communities. Results show that the eDNA approach can enable the determination of zooplankton diversity through

    As overweight and obesity is a risk factor for chronic diseases, the development of environmental and healthy public policy interventions across multiple sectors has been identified as a key strategy to address this issue. In 2009, a survey was developed to assess the attitudes and beliefs regarding health promotion principles, and the priority and acceptability of policy actions to prevent obesity and chronic diseases, among key policy influencers in Alberta and Manitoba, Canada. Surveys were mailed to 1,765 key influencers from five settings: provincial government, municipal government, school boards, print media companies, and workplaces with greater than 500 employees. A total of 236 surveys were completed with a response rate of 15.0%. Findings indicate nearly unanimous influencer support for individual-focused policy approaches and high support for some environmental policies. Restrictive environmental and economic policies received weakest support. Obesity was comparable to smoking with respect to perceptions as a societal responsibility versus a personal responsibility, boding well for the potential of environmental policy interventions for obesity prevention. This level of influencer support provides a platform for more evidence to be brokered to policy influencers about the effectiveness of environmental policy approaches to obesity prevention. © 2014 The Obesity Society.

    The purpose of this work was to investigate incentives and barriers to fuel ethanol production from biomass in the U.S. during the past decade (2000-2010). In particular, we examine the results of policies and economic conditions during this period by way of cellulosic ethanol activity in four selected states with the potential to produce different types of feedstocks (i.e., sugar, starch, and cellulosic crops) for ethanol production (Florida, California, Hawaii, and Iowa). Two of the four states, Iowa and California, currently have commercial ethanol production facilities in operation using corn feedstocks. While several companies have proposed commercial scale facilities in Florida and Hawaii, none are operating to date. Federal and state policies and incentives, potential for feedstock production and conversion to ethanol and associated potential environmental impacts, and environmental regulatory conditions among the states were investigated. Additionally, an analysis of proposed and operational ethanol production facilities provided evidence that a combination of these policies and incentives along with the ability to address environmental issues and regulatory environment and positive economic conditions all impact ethanol production. The 2000-2010 decade saw the rise of the promise of cellulosic ethanol. Federal and state policies were enacted to increase ethanol production. Since the initial push for development, expansion of cellulosic ethanol production has not happened as quickly as predicted. Government and private funding supported the development of ethanol production facilities, which peaked and then declined by the end of the decade. Although there are technical issues that remain to be solved to more efficiently convert cellulosic material to ethanol while reducing environmental impacts, the largest barriers to increasing ethanol production appear to be related to government policies, economics, and logistical issues.

    Some of the ethical, environmental and social issues relating to the design and use of machine vision systems in manufacturing industry are highlighted. The authors' aim is to emphasize some of the more important issues, and raise general awareness of the need to consider the potential advantages and hazards of machine vision technology. However, in a short article like this, it is impossible to cover the subject comprehensively. This paper should therefore be seen as a discussion document, which it is hoped will provoke more detailed consideration of these very important issues. It follows from an article presented at last year's workshop. Five major topics are discussed: (1) The impact of machine vision systems on the environment; (2) The implications of machine vision for product and factory safety, the health and well-being of employees; (3) The importance of intellectual integrity in a field requiring a careful balance of advanced ideas and technologies; (4) Commercial and managerial integrity; and (5) The impact of machine visions technology on employment prospects, particularly for people with low skill levels.

    Urgent environmental issues are testing the limits of current management approaches and pushing demand for innovative approaches that integrate across traditional disciplinary boundaries. Practitioners, scholars, and policy-makers alike call for increased integration of natural and social sciences to develop new approaches that address the range of ecological and societal impacts of modern environmental issues. From a theoretical perspective, social-ecological systems (SES) science offers a compelling approach for improved environmental management through the application of transdisciplinary and resilience concepts. A framework for translating SES theory into practice, however, is lacking. In this paper, we define the key components of an SES-based environmental management approach. We offer recommendations for integrating an SES approach into existing environmental management practices. Results presented are useful for management professionals that seek to employ an SES environmental management approach and scholars aiming to advance the theoretical foundations of SES science for practical application.

    Mainstream entertainment’s influence on our cognition, emotions, and behavior is often profound. Mass media permeates both the public and private spheres of society, saturating communities with messages from a diverse range of sources. While advertisers regularly take advantage of the extensive reach and influence of the media, social scientists, policy makers, and nonprofits have seen little success in incorporating social and environmental messaging into entertainment. Harmony Institute’s goal is to harness the power of mainstream media to provide US audiences with entertainment that educates on social and environmental issues and increases both individual and community action. The entertainment the Institute helps to produce connects with viewers on both a cognitive and emotional level. The Institute uses innovative methods across disciplines in order to measure entertainment’s impact and influence. Since its founding two years ago, the Institute has worked on a wide range of projects that have helped to establish its methodology for measured impact that applies behavioral science theory and entertainment to social and environmental issues. Projects spanning media platforms and social/environmental issues have included a web serial drama incorporating issues of water conservation and ocean stewardship into the narrative and a fotonovela for Hispanic youth in Houston focused on local environmental issues. In summer 2010, the Harmony Institute released FTW! Net Neutrality For The Win: How Entertainment and the Science of Influence Can Save Your Internet, an issue-specific communications guide about open Internet access that explains how to craft a communications strategy that connects with audiences using behavioral science research findings. In 2010-2011, the Institute will focus on measuring the impact and influence that media can have on social and environmental issues. The Institute has developed a comprehensive media evaluation methodology that employs

  11. Risk assessment of antibiotic residues in different water matrices in India: key issues and challenges.

    Mutiyar, Pravin K; Mittal, Atul K

    2014-06-01

    Global detection of antibiotic substances in water matrices has considerably increased in the recent past. However, in India research on this issue is limited or generalised in the literature. Risks associated with the presence of antibiotics in the environment can be quantified using a hazard quotient (HQ) approach. Here, HQs were developed using the measured environmental concentration (MEC) approach for antibiotic residues in Indian water matrices previously reported in the literature. In the present study, environmental risk assessment, using the HQ index [HQ = measured environmental concentration (MEC)/predicted no effect concentration (PNEC)] for different antibiotics, was performed according to the guidelines of European Medicine Evaluation Agency (EMEA). MEC and PNEC levels were obtained from the literature. PNEC values were also calculated from EC50 using a safety factor when no PNECs were reported in the literature. HQs were obtained for industrial effluents (HQ = 10(4)) that were greater than any previously reported values. Ciprofloxacin, a fluoroquinolone antibiotic, seemed to present the greatest risk in India. The HQ indices for Indian water matrices were in the following order: industrial effluents > lake water > river water > hospital effluents > treated sewage ≃ groundwater. A very high HQ represents a potential environmental concern for aquatic environments in India and demands that immediate attention be devoted to regulating these compounds, especially in pharmaceutical industrial wastewater.

  12. Psychosocial assistance after environmental accidents: a policy perspective.

    PubMed Central

    Becker, S M

    1997-01-01

    There is a substantial body of literature on psychosocial impacts of chemical and nuclear accidents. Less attention, however, has been focused on the program and policy issues that are connected with efforts to provide psychosocial assistance to the victims of such accidents. Because psychosocial assistance efforts are certain to be an essential part of the response to future environmental emergencies, it is vital that relevant program and policy issues by more fully considered. This article discusses the highly complex nature of contamination situations and highlights some of the key policy issues that are associated with the provision of psychosocial services after environmental accidents. One issue concerns the potential for assistance efforts to become objects of conflict. In the context of the intense controversy typically associated with chemical or nuclear accidents, and with debates over the causation of illness usually at the center of environmental accidents, psychosocial assistance services may themselves become contested terrain. Other significant program and policy issues include determining how to interface with citizen self-help and other voluntary groups, addressing the problem of stigma, and deciding how to facilitate stakeholder participation in the shaping of service provision. This article offers a series of policy proposals that may help smooth the way for psychosocial assistance programs in future environmental emergencies. PMID:9467082

    Background Studying the impact of environmental exposures is important in children because they are more vulnerable to adverse effects on growth, development, and health. Assessing exposure in children is difficult, and measuring biomarkers is potentially useful. Research measuring biomarkers in children raises a number of ethical issues, some of which relate to children as research subjects and some of which are specific to biomarker research. Objective As an international group with experience in pediatric research, biomarkers, and the ethics of research in children, we highlight the ethical issues of undertaking biomarker research in children in these environments. Discussion Significant issues include undertaking research in vulnerable communities, especially in developing countries; managing community expectations; obtaining appropriate consent to conduct the research; the potential conflicts of obtaining permission from an ethics review board in an economically developed country to perform research in a community that may have different cultural values; returning research results to participants and communities when the researchers are uncertain of how to interpret the results; and the conflicting ethical obligations of maintaining participant confidentiality when information about harm or illegal activities mandate reporting to authorities. Conclusion None of these challenges are insurmountable and all deserve discussion. Pediatric biomarker research is necessary for advancing child health. PMID:19672395

    1994-12-01

    The U.S. Department of Energy (DOE) chartered the Phosphoric Acid Fuel-Cell (PAFC) Bus Program to demonstrate the feasibility of fuel cells in heavy-duty transportation systems. As part of this program, PAFC- powered buses are being built to meet transit industry design and performance standards. Test-bed bus-1 (TBB-1) was designed in 1993 and integrated in March 1994. TBB-2 and TBB-3 are under construction and should be integrated in early 1995. In 1987 Phase 1 of the program began with the development and testing of two conceptual system designs- liquid- and air-cooled systems. The liquid-cooled PAFC system was chosen to continue, through a competitive award, into Phase H, beginning in 1991. Three hybrid buses, which combine fuel-cell and battery technologies, were designed during Phase 3. After completing Phase 2, DOE plans a comprehensive performance testing program (Phase H1) to verify that the buses meet stringent transit industry requirements. The Phase 3 study will evaluate the PAFC bus and compare it to a conventional diesel bus. This NREL study assesses the environmental, health, and safety (EH&S) issues that may affect the commercialization of the PAFC bus. Because safety is a critical factor for consumer acceptance of new transportation-based technologies the study focuses on these issues. The study examines health and safety together because they are integrally related. In addition, this report briefly discusses two environmental issues that are of concern to the Environmental Protection Agency (EPA). The first issue involves a surge battery used by the PAFC bus that contains hazardous constituents. The second issue concerns the regulated air emissions produced during operation of the PAFC bus.

  19. Using Eight Key Questions as an Inquiry-Based Framework for Ethical Reasoning Issues in a General Education Earth Systems and Climate Change Course

    Johnson, E. A.; Ball, T. C.

    2014-12-01

    An important objective in general education geoscience courses is to help students evaluate social and ethical issues based upon scientific knowledge. It can be difficult for instructors trained in the physical sciences to design effective ways of including ethical issues in large lecture courses where whole-class discussions are not practical. The Quality Enhancement Plan for James Madison University, "The Madison Collaborative: Ethical Reasoning in Action," (http://www.jmu.edu/mc/index.shtml) has identified eight key questions to be used as a framework for developing ethical reasoning exercises and evaluating student learning. These eight questions are represented by the acronym FOR CLEAR and are represented by the concepts of Fairness, Outcomes, Responsibilities, Character, Liberty, Empathy, Authority, and Rights. In this study, we use the eight key questions as an inquiry-based framework for addressing ethical issues in a 100-student general education Earth systems and climate change course. Ethical reasoning exercises are presented throughout the course and range from questions of personal behavior to issues regarding potential future generations and global natural resources. In the first few exercises, key questions are identified for the students and calibrated responses are provided as examples. By the end of the semester, students are expected to identify key questions themselves and justify their own ethical and scientific reasoning. Evaluation rubrics are customized to this scaffolding approach to the exercises. Student feedback and course data will be presented to encourage discussion of this and other approaches to explicitly incorporating ethical reasoning in general education geoscience courses.

    The development of new resources to evaluate the environmental status is becoming increasingly important representing a key challenge for ocean and coastal management. Recently, the employment of transcriptomics in aquatic toxicology has led to increasing initiatives proposing to integrate eco-toxicogenomics in the evaluation of marine ecosystem health. However, several technical issues need to be addressed before introducing genomics as a reliable tool in regulatory ecotoxicology. The Venice lagoon constitutes an excellent case, in which the assessment of environmental risks derived from the nearby industrial activities represents a crucial task. In this context, the potential role of genomics to assist environmental monitoring was investigated through the definition of reliable gene expression markers associated to chemical contamination in Manila clams, and their subsequent employment for the classification of Venice lagoon areas. Overall, the present study addresses key issues to evaluate the future outlooks of genomics in the environmental monitoring and risk assessment. Copyright © 2014 Elsevier Ltd. All rights reserved.

  1. Environmental Issues in Thyroid Diseases.

    Environmental factors are determinant for the appearance of autoimmune thyroid diseases (AITD) in susceptible subjects. Increased iodine intake, selenium, and vitamin D deficiency, exposure to radiation, from nuclear fallout or due to medical radiation, are environmental factors increasing AITD. Cigarette smoking is associated with Graves' disease and Graves' ophthalmopathy, while it decreases the risk of hypothyroidism and thyroid autoimmunity. Viral infections are important environmental factors in the pathogenesis of AITD, too, particularly human parvovirus B19 (EVB19) and hepatitis C virus. Among the many chemical contaminants, halogenated organochlorines and pesticides variably disrupt thyroid function. Polychlorinated biphenyls and their metabolites and polybrominated diethyl ethers bind to thyroid transport proteins, such as transthyretin, displace thyroxine, and disrupt thyroid function. Among drugs, interferon- and iodine-containing drugs have been associated with AITD. Moreover intestinal dysbiosis causes autoimmune thyroiditis. To reduce the risk to populations and also in each patient, it is necessary to comprehend the association between environmental agents and thyroid dysfunction.

    Objectives To diagnose the capabilities that environmental authorities and the Ministry of Environment and Sustainable Development have to assume their role in environmental health, based on the capacity model of the United Nations Program for Development UNDP. Method Document review, interviews on key issues and a commented survey were conducted. 84 entities were selected for a tailored survey; complete information was obtained from 76 institutions. Results The valuation of environment favorability was within the acceptable and unfavorable categories; knowledge management capabilities were found to be precarious and assessment of functional capabilities ranged between appropriate and acceptable. The assessment of specific capabilities had a rating of poor or barely acceptable. Conclusions Two major problems were found: a. The environmental authorities do not conceive or implement these capabilities based on the UNDP model but on the conventional model of the Ministry of Environment, Housing and Territorial Development; b. Environmental authorities show an incipient level of incorporation of environmental health policies in their field of action.

    Bioleaching is considered to be a low-cost, eco-friendly technique for leaching valuable metals from a variety of matrixes. However, the inherent slow dissolution kinetics and low metal leaching yields have restricted its wider commercial applicability. Recent advancements in bio-hydrometallurgy have suggested that these critical issues can be successfully alleviated through the addition of a catalyst. The catalyzing properties of a variety of metals ions (Ag + , Hg ++ , Bi +++ , Cu ++ , Co ++ etc.) during bioleaching have been successfully demonstrated. In this article, the role and mechanisms of these metal species in catalyzing bioleaching from different minerals (chalcopyrite, complex sulfides, etc.) and waste materials (spent batteries) are reviewed, techno-economic and environmental challenges associated with the use of metals ions as catalysts are identified, and future prospectives are discussed. Based on the analysis, it is suggested that metal ion-catalyzed bioleaching will play a key role in the development of future industrial bio-hydrometallurgical processes.

    2014-06-01

    Environmental contaminants monitoring is one of the key issues in understanding and managing hazards to human health and ecosystems. In this context, aptamer based electrochemical sensors have achieved intense significance because of their capability to resolve a potentially large number of problems and challenges in environmental contamination. An aptasensor is a compact analytical device incorporating an aptamer (oligonulceotide) as the sensing element either integrated within or intimately associated with a physiochemical transducer surface. Nucleic acid is well known for the function of carrying and passing genetic information, however, it has found a key role in analytical monitoring during recent years. Aptamer based sensors represent a novelty in environmental analytical science and there are great expectations for their promising performance as alternative to conventional analytical tools. This review paper focuses on the recent advances in the development of aptamer based electrochemical sensors for environmental applications with special emphasis on emerging pollutants.

  9. Does Evidence Matter? How Middle School Students Make Decisions About Socioscientific Issues

    NASA Astrophysics Data System (ADS)

    Emery, Katherine Beth

    People worldwide are faced with making decisions daily. While many decisions are quick (e.g., what clothes to wear), others, such as those about environmental issues (e.g., overfishing), require more thought and have less immediate outcomes. How one makes such decisions depends on how one interprets, evaluates, and uses evidence. The central objective of this thesis was to investigate environmental science literacy in general, and specifically, to understand how evidence and other factors impact decision-making. I conducted three main studies: First, I provide an example of how decision-making practices affect environmental systems and services through a descriptive case study of Atlantic bluefin tuna overfishing. I reviewed the scientific, historical and cultural factors contributing to a paradox of marine preservation in the Mediterranean and highlighted the need for education and informed decision-making about such social and ecological issues. This study motivated me to investigate how people make decisions about environmental issues. Second, I interviewed middle school students to understand how they describe and evaluate evidence hypothetically and in practice about environmental issues---a key component of environmental literacy. Students discussed how they would evaluate evidence and then were then given a packet containing multiple excerpts of information from conflicting stakeholders about an environmental issue and asked how they would make voting or purchasing decisions about these issues. Findings showed that students' ideas about evaluating evidence (e.g., by scientific and non-scientific criteria) match their practices in part. This study was unique in that it investigated how students evaluate evidence that (1) contradicts other evidence and (2), conflicts with the student's prior positions. Finally, I investigated whether middle school students used evidence when making decisions about socioscientific issues. I hypothesized that holding a strong

    2015-01-01

    Systemic lupus erythematous (SLE) is a chronic multisystem disease with significant associated morbidity and mortality. A deeper understanding of the pathogenesis of SLE has led to the development of biologic agents, primarily targeting B cells and others inhibiting costimulatory molecules, type I interferons and cytokines such as interleukin-6. Several of these agents have been studied in clinical trials; some have shown promise while others have yielded disappointing results. Economic and regulatory issues continue to hamper the availability of such therapies for SLE patients. With increasing recognition that recurrent flares of disease activity lead to long-term damage accrual, one of the most important recent developments in patient management has been the concept of treat-to-target in SLE while minimizing patient exposure to excessive corticosteroid and other immunosuppressive therapy. This article reviews these key issues in SLE management, outlining recent developments and clinical implications for patients. PMID:26622325

    Renewable energy technologies offer the promise of non-polluting alternatives to fossil and nuclear-fueled power plants to meet growing demand for electrical energy. Two emerging categories of renewable energy technologies, hydrokinetic and wave energy conversion devices, offer ways to tap the energy of moving water without impoundment (dams) or diversion required by many conventional hydroelectric facilities. These technologies include devices designed for deployment in natural streams, tidal estuaries, ocean currents, and constructed waterways, as well as devices designed to capture the energy of ocean waves. On October 26-28, 2005, 54 representatives from government, non-governmental organizations, and private business met to (1)more » identify the varieties of hydrokinetic energy and wave technology devices, their stages of development, and the projected cost to bring each to market; (2) identify where these technologies can best operate; (3) identify the potential environmental issues associated with these technologies and possible mitigation measures; (4) develop a list of research needs and/or practical solutions to address unresolved environmental issues.

    The present article provides a multifaceted critical research review on environmental issues intimately related with the socio-economy of North East India (NE), a part of Indo-Burma hotspot. Further, the article addresses the issue of sustainable development of NE India through diverse ecological practices inextricably linked with traditional ecological knowledge (TEK). The biodiversity of NE India comprises endemic floral diversity, particularly medicinal plants of importance to pharmaceutical industry, and unique faunal diversity. Nevertheless, it is very unfortunate that this great land of biodiversity is least explored taxonomically as well as biotechnologically, probably due to geographical and political constraints. Different anthropogenic and socio-economic factors have perturbed the pristine ecology of this region, leading to environmental degradation. Also, the practice of unregulated shifting cultivation (jhooming), bamboo flowering, biological invasions and anthropogenic perturbations to biodiversity exacerbate the gloomy situation. Instead of a plethora of policies, the TEK of NE people may be integrated with modern scientific knowledge in order to conserve the environment which is the strong pillar for socio-economic sector here. The aforesaid approach can be practiced in NE India through the broad implementation and extension of agroforestry practices. Further, case studies on Apatanis, ethnomedicinal plants use by indigenous tribal groups and sacred forests are particularly relevant in the context of conservation of environmental health in totality while addressing the socioeconomic impact as well. In context with the prevailing scenarios in this region, we developed an eco-sustainable model for natural resource management through agroforestry practices in order to uplift the social as well as environmental framework.

    In 2014 Gemini Observatory started the base facility operations (BFO) project. The project's goal was to provide the ability to operate the two Gemini telescopes from their base facilities (respectively Hilo, HI at Gemini North, and La Serena, Chile at Gemini South). BFO was identified as a key project for Gemini's transition program, as it created an opportunity to reduce operational costs. In November 2015, the Gemini North telescope started operating from the base facility in Hilo, Hawaii. In order to provide the remote operator the tools to work from the base, many of the activities that were normally performed by the night staff at the summit were replaced with new systems and tools. This paper describes some of the key systems and tools implemented for environmental monitoring, and the design used in the implementation at the Gemini North telescope.

    The Baltic Sea is especially susceptible to multiple human impacts due to its estuarine mixing patterns and long water residence times. Temporally and spatially, it is one of the best investigated marginal seas worldwide allowing for a deep knowledge of natural and human processes forming this unique brackish ecosystem. In this presentation, we shortly summarize the physical, biogeochemical and ecological settings of the Baltic Sea and address major human drivers and pressures threatening its ecosystem. Further, we summarize the scientific and political efforts that led to the formulation of Baltic Sea Action Plan, a milestone for eutrophication management and European environmental governance. Further, we summarize the efforts and societal pitfalls towards an Ecosystem Based Fisheries Management, strategies to decrease loads of environmental pollutants and management of marine biodiversity/habitat issues in the unique Baltic Sea context.

    2010-12-01

    The Earth is a complex, interacting system which cannot be neatly divided by discipline boundaries. To gain an holistic understanding of even a component of an Earth System requires researchers to draw information from multiple disciplines and integrate these to develop a broader understanding. But the barriers to achieving this are formidable. Research funders attempting to encourage the integration of information across disciplines need to take into account culture issues, the impact of intrusion of projects on existing information systems, ontologies and semantics, scale issues, heterogeneity and the uncertainties associated with combining information from diverse sources. Culture - There is a cultural dualism in the environmental sciences were information sharing is both rewarded and discouraged. Researchers who share information both gain new opportunities and risk reducing their chances of being first author in an high-impact journal. The culture of the environmental science community has to be managed to ensure that information fusion activities are encouraged. Intrusion - Existing information systems have an inertia of there own because of the intellectual and financial capital invested within them. Information fusion activities must recognise and seek to minimise the potential impact of their projects on existing systems. Low intrusion information fusions systems such as OGC web-service and the OpenMI Standard are to be preferred to whole-sale replacement of existing systems. Ontology and Semantics - Linking information across disciplines requires a clear understanding of the concepts deployed in the vocabulary used to describe them. Such work is a critical first step to creating routine information fusion. It is essential that national bodies, such as geological surveys organisations, document and publish their ontologies, semantics, etc. Scale - Environmental processes operate at scales ranging from microns to the scale of the Solar System and

    Environmental planners and managers face unique challenges understanding and documenting the effectiveness of programs that rely on voluntary actions by private landowners. Programs, such as those aimed at reducing nonpoint source pollution or improving habitat, intend to reach those goals by persuading landowners to adopt behaviors and management practices consistent with environmental restoration and protection. Our purpose with this paper is to identify barriers for improving voluntary environmental management programs and ways to overcome them. We first draw upon insights regarding data, learning, and adaptation from the adaptive management and performance management literatures, describing three key issues: overcoming information constraints, structural limitations, and organizational culture. Although these lessons are applicable to a variety of voluntary environmental management programs, we then present the issues in the context of on-going research for nonpoint source water quality pollution. We end the discussion by highlighting important elements for advancing voluntary program efforts.

    The U.S. Department of Energy (DOE) chartered the Phosphoric Acid Fuel-Cell (PAFC) Bus Program to demonstrate the feasibility of fuel cells in heavy-duty transportation systems. As part of this program, PAFC- powered buses are being built to meet transit industry design and performance standards. Test-bed bus-1 (TBB-1) was designed in 1993 and integrated in March 1994. TBB-2 and TBB-3 are under construction and should be integrated in early 1995. In 1987 Phase I of the program began with the development and testing of two conceptual system designs- liquid- and air-cooled systems. The liquid-cooled PAFC system was chosen to continue, throughmore » a competitive award, into Phase H, beginning in 1991. Three hybrid buses, which combine fuel-cell and battery technologies, were designed during Phase III. After completing Phase II, DOE plans a comprehensive performance testing program (Phase HI) to verify that the buses meet stringent transit industry requirements. The Phase III study will evaluate the PAFC bus and compare it to a conventional diesel bus. This NREL study assesses the environmental, health, and safety (EH&S) issues that may affect the commercialization of the PAFC bus. Because safety is a critical factor for consumer acceptance of new transportation-based technologies the study focuses on these issues. The study examines health and safety together because they are integrally related. In addition, this report briefly discusses two environmental issues that are of concern to the Environmental Protection Agency (EPA). The first issue involves a surge battery used by the PAFC bus that contains hazardous constituents. The second issue concerns the regulated air emissions produced during operation of the PAFC bus.« less

    Environmentally acquired asbestos-related diseases (ARDs) are of concern globally. In South Africa, there is widespread contamination of the environment due to historical asbestos mining operations that were poorly regulated. Although the law makes provision for the compensation of occupationally acquired ARDs, compensation for environmentally acquired ARDs is only available through the Asbestos Relief Trust (ART) and Kgalagadi Relief Trust, both of which are administered by the ART. This study assessed ARDs and compensation outcomes of environmental claims submitted to the Trusts. The personal details, medical diagnoses, and exposure information of all environmental claims considered by the Trusts from their inception in 2003 to April 2010 were used to calculate the numbers and proportions of ARDs and compensation awards. There were 146 environmental claimants of whom 35 (23.9%) had fibrotic pleural disease, 1 (0.7%) had lung cancer, and 77 (52.7%) had malignant mesothelioma. 53 (36.3%) claimants were compensated: 20 with fibrotic pleural disease and 33 with mesothelioma. Of the 93 (63.7%) claimants who were not compensated, 33 had no ARDs, 18 had fibrotic pleural disease, 1 had lung cancer, and 44 had mesothelioma. In addition to having ARDs, those that were compensated had qualifying domestic (33; 62.2%) or neighbourhood (20; 37.8%) exposures to asbestos. Most of the claimants who were not compensated had ARDs but their exposures did not meet the Trusts' exposure criteria. This study demonstrates the environmental impact of asbestos mining on the burden of ARDs. Mesothelioma was the most common disease diagnosed, but most cases were not compensated. This highlights that there is little redress for individuals with environmentally acquired ARDs in South Africa. To stop this ARD epidemic, there is a need for the rehabilitation of abandoned asbestos mines and the environment. These issues may not be unique to South Africa as many countries continue to mine and use

    Simulation skills centers (SSC) are considered important learning arenas for preparing and qualifying nursing students. Limited clinical placements and claims of diminished learning opportunities raise concerns that newly educated nurses lack proficiency in many psychomotor skills. Accordingly, there is an increased focus on learning in the SSC. However, it has been questioned if the pedagogical underpinning of teaching and learning in the SSC is missing or unclear. At a bachelor nursing education in Norway, there was a desire to change practice and enhance learning in the SSC by systematic use of The Model of Practical Skill Performance (Bjørk and Kirkevold, 2000). A participatory action research design was chosen. A pedagogical intervention was developed and implemented in 2010 in a cohort of eighty-seven first year bachelor nursing students during their basic nursing skill course. The intervention is shortly described. This article reports key issues and challenges that emerged during development of the new intervention. Data to inform the study were collected via thorough meeting minutes and the project leader's logbook, and analyzed using fieldnotes analysis. Six key issues and challenges were identified. These are presented and discussed consecutively in light of their importance for development and implementation of the new intervention. Copyright © 2013 Elsevier Ltd. All rights reserved.

In this work, the OH A{sup 2}Σ{sup +}→X{sup 2}Π ultraviolet emission band behind the bow shock is computed under the experimental condition of the second bow-shock ultraviolet flight (BSUV-2). Four related key issues are discussed, namely, the source of hydrogen element in the high-altitude atmosphere, the formation mechanism of OH species, efficient computational algorithm of trace species in rarefied flows, and accurate calculation of OH emission spectra. Firstly, by analyzing the typical atmospheric model, the verticalmore » distributions of the number densities of different species containing hydrogen element are given. According to the different dominating species containing hydrogen element, the atmosphere is divided into three zones, and the formation mechanism of OH species is analyzed in the different zones. The direct simulation Monte Carlo (DSMC) method and the Navier-Stokes equations are employed to compute the number densities of the different OH electronically and vibrationally excited states. Different to the previous work, the trace species separation (TSS) algorithm is applied twice in order to accurately calculate the densities of OH species and its excited states. Using a non-equilibrium radiation model, the OH ultraviolet emission spectra and intensity at different altitudes are computed, and good agreement is obtained with the flight measured data.« less

At present, the most widely used means of measuring environmental attitudes is the New Environmental Paradigm (NEP) Scale. This dissertation chronicles the development and establishment of the NEP and the important role it has played in social science research. It also reviews key empirical and theoretical critiques of the scale, arguing that the worldview embodied by the NEP is representative of a narrow understanding of pro-environmental thought and that there remains the need for a new scale built using the core dimensions underlying contemporary environmentalism's diversity. Based on an assessment of contemporary environmental discourse, it was theorized that the key areas in which environmentalists diverge are with respect to nature, technology, and scale of societal response. To test this assertion, this project deeply explored a small sample of carefully selected participants with strong environmental identities and diverse attitudes and values. Quantitative and qualitative data was collected using survey question items and in-depth Repertory Grid interviews. Foremost, analysis showed that the sample of environmentalists studied were far from ideologically homogenous. While they agreed with respect to certain issues, such as the seriousness of environmental problems and the inability of the earth to accommodate unlimited resource demands, they also disagreed in key areas, such as the ability of technology to solve environmental problems and the scale at which effective change occurs. With respect to effective environmental problem solving, respondents mentioned green technologies, reducing resource consumption, and policy changes, and they differentiated between these solutions based on cost, the type of social change needed to bring these solutions to fruition, and how difficult they would be to enact. Demographic differences were also assessed

    Traditional hazards such as poor sanitation currently account for most of Africa's environmentally related disease burden. However, with rapid development absent appropriate safeguards for environment and health, modern environmental health hazards (MEHHs) may emerge as critical contributors to the continent's disease burden. We review recent evidence of human exposure to and health effects from MEHHs, and their occurrence in environmental media and consumer products. Our purpose is to highlight the growing significance of these hazards as African countries experience urbanization, industrial growth, and development. We reviewed published epidemiologic, exposure, and environmental studies of chemical agents such as heavy metals and pesticides. The body of evidence demonstrates ongoing environmental releases of MEHHs and human exposures sometimes at toxicologically relevant levels. Several sources of MEHHs in environmental media have been identified, including natural resource mining and processing and automobile exhaust. Biomonitoring studies provided direct evidence of human exposure to metals such as mercury and lead and pesticides such as p,p'-dichlorodiphenyltrichloroethane (DDT) and organophosphates. Land and water resource pollution and industrial air toxics are areas of significant data gaps, notwithstanding the presence of several emitting sources. Unmitigated MEHH releases and human exposure have implications for Africa's disease burden. For Africans encumbered by conditions such as malnutrition that impair resilience to toxicologic challenges, the burden may be higher. A shift in public health policy toward accommodating the emerging diversity in Africa's environmental health issues is necessary to successfully alleviate the burden of avoidable ill health and premature death for all its communities now and in the future.

    Profound environmental change in the Arctic region is driving an urgent need for faster and more efficient knowledge creation and delivery for residents of the Arctic as well as stakeholders around the globe. The overarching issues at play include environmental stewardship, community health and cultural survival. To effectively address these issues, the Interagency Arctic Research Policy Committee (IAPRC) recently established the Environmental Intelligence Collaboration Team (EICT) that integrates observing capabilities, modelling efforts and data management. Since its inception, the EICT has been working to create pathways to environmental knowledge that sustains end-to-end integration of research across the linked steps of data integration, environmental observing, predictive modelling, assessing responsiveness to stakeholder needs and ultimately providing decision support. The EICT is currently focusing on the carbon-climate aspect of environmental knowledge and identifing specific decision-making needs to meet policy goals for topics such as carbon emissions from permafrost thaw, increasing wildfire frequency and ocean acidification. As a case study, we applied the Environmental Intelligence framework to understanding the effects of ocean acidification in southern Alaska where there are critical commercial and subsistence fisheries. The results of this work revealed that there is currently a 5-month window of optimal growing conditions at a hatchery facility for many juvenile shellfish although that window is expected to close by 2040. The outcome of this work relates directly to fisheries management decisions and identifies the need for continued Environmental Intelligence collection to monitor and mitigate ocean acidification in the Alaskan region.

    News media play a powerful role in disseminating and framing information and shaping public opinion on environmental issues. Choices of text and images that are made by the creators and distributors of news media not only influence public perception about which issues are important, but also surreptitiously lead consumers of these media to perceive certain aspects or perspectives on an issue while neglecting to consider others. Our research was motivated by a desire to obtain comprehensive quantitative and qualitative understanding of the types of information - both textual and visual -- that have been provided to the U.S. public over the past several decades through news reports about climate change. As part of this project, we documented and examined 118 themes in 19 categories presented in 350 randomly-selected visual images from U.S. news coverage of global climate change between 1969 and late 2009. This study examines how the use of imagery in print news positions climate change within public and private arenas and how it emphasizes particular geographic, political, scientific, technological, sociological, and ideological aspects of the issue.

  16. Epidemiological Data Management during an Outbreak of Ebola Virus Disease: Key Issues and Observations from Sierra Leone.

    Sierra Leone experienced intense transmission of Ebola virus disease (EVD) from May 2014 to November 2015 during which a total of 8,704 confirmed cases and over 3,589 confirmed deaths were reported. Our field observation showed many issues in the EVD data management system, which may have contributed to the magnitude and long duration of the outbreak. In this perspective article, we explain the key issues with EVD data management in the field, and the resulting obstacles in analyzing key epidemiological indicators during the outbreak response work. Our observation showed that, during the latter part of the EVD outbreak, surveillance and data management improved at all levels in the country as compared to the earlier stage. We identified incomplete filling and late arrival of the case investigation forms at data management centers, difficulties in detecting double entries and merging identified double entries in the database, and lack of clear process of how death of confirmed cases in holding, treatment, and community care centers are reported to the data centers as some of challenges to effective data management. Furthermore, there was no consolidated database that captured and linked all data sources in a structured way. We propose development of a new application tool easily adaptable to new occurrences, regular data harmonization meetings between national and district data management teams, and establishment of a data quality audit system to assure good quality data as ways to improve EVD data management during future outbreaks.

    The scope of this publication is a presentation of environmental issues and process risks connected with operation an installation for carbon capture from waste gas. General technological assumptions, typical for demonstration plant for carbon capture from waste gas (DCCP) with application of two different solutions - 30% water solution of monoethanoloamine (MEA) and water solution with 30% AMP (2-amino-2-methyl-1-propanol) and 10% piperazine have been described. The concept of DCCP installation was made for Łaziska Power Plant in Łaziska Górne owned by TAURON Wytwarzanie S.A. Main hazardous substances, typical for such installation, which can be dangerous for human life and health or for the environment have been presented. Pollution emission to the air, noise emission, waste water and solid waste management have been described. The environmental impact of the released substances has been stated. Reference to emission standards specified in regulations for considered substances has been done. Principles of risk analysis have been presented and main hazards in carbon dioxide absorption node and regeneration node have been evaluated.

    The Severn Estuary and Bristol Channel encompass a number of designated sites supporting populations of waterbirds and seabirds that are of national or international importance, including the Severn Estuary and Burry Inlet Special Protection Areas (SPAs)/Ramsar Sites and Carmarthen Bay, the UK's first marine SPA. Here, we provide an overview of the present numbers and trends of the waterbirds and seabirds using these sites, updating previous reviews undertaken prior to these designations. We further provide a summary of the main issues that have affected the status of the area's bird populations. Declines in the numbers of waders on the Severn Estuary and the southwest over the last two decades have been linked to climate change. The Sea Empress oil-spill impacted both breeding seabirds and the wintering Common Scoters in Carmarthen Bay, though numbers of the latter recovered 3years after the spill. At the Burry Inlet, Oystercatcher numbers have fallen over the last 25years and considerable research has been undertaken into the conflict with cockle and mussel fisheries. A long-term study at Cardiff Bay, at the mouth of the Severn, revealed a significant impact on the survival of Redshanks following its impoundment and has helped to further understanding of responses of waterbirds to estuarine habitat loss. The potential impacts of the construction of a tidal power scheme on the Severn Estuary are also discussed. (c) 2009 Elsevier Ltd. All rights reserved.

    The Southeast CARE Coalition has been using community-based participatory research to examine environmental degradation in the Southeast Community, Newport News, Virginia. A survey was developed to collect assessment data. Up to 66% of respondents were concerned about environmental problems in their community. Those with health conditions were significantly more likely to identify specific environmental problems. The top 5 environmental concerns included coal dust, air quality, crime, water quality, and trash. The community-based participatory research process is building community capacity and participation, providing community input into strategic planning, and empowering community members to take control of environmental justice issues in their community.

  3. Environmental issues of petroleum exploration and production: Introduction

    Kharaka, Yousif K.; Dorsey, Nancy S.

    2005-01-01

    Energy is the lifeblood of our planet Earth, an essential commod- ity that powers the expanding global economy. Starting in the 1950s, oil and natural gas became the main sources of primary energy for the increasing world population, and this dominance is expected to continue for several more decades (Edwards, 1997; Energy Information Administration (EIA), 2004). In the United States, petroleum production started in 1859 when Drake's well was drilled near Titusville, Pennsylvania, and oil and natural gas currently supply approximately 63% of the energy consumption; forecasts indicate that by 2025, their use will increase by about 40% to 28.3 million bbl/day and to 31.4 tcf/yr (EIA, 2004). The clear benefits of petroleum consumption, however, can carry major environmental impacts that may be regional or global in scale, in- cluding air pollution, global climate change, and oil spills. This vol- ume of Environmental Geosciences, covering environmental impacts of petroleum exploration and production, does not address these major impacts directly because air pollution and global warming are issues related primarily to petroleum and coal uses, and major oil spills are generally attributed to marine petroleum transportation, such as the Exxon Valdez's 1989 spill of 260,000 bbl of oil into Prince William Sound, Alaska. Exploration for and production of petroleum, however, have caused local detrimental impacts to soils, surface and groundwa- ters, and ecosystems in the 36 producing states in the United States (Richter and Kreitler, 1993; Kharaka and Hanor, 2003). These im- pacts arose primarily from the improper disposal of some of the large volumes (presently estimated at 20 billion bbl/yr total pro- duced) of saline water produced with oil and gas, from accidental hydrocarbon and produced-water releases, and from abandoned oil wells that were orphaned or not correctly plugged (Kharaka et al., 1995; Veil et al., 2004).

    The future appears rich in missions that will extend the frontiers of knowledge, human presence in space, and opportunities for profitable commerce. Key to the success of these ventures is the availability of plentiful, cost effective electric power and assured, low cost access to space. While forecasts of space power needs are problematic, an assessment of future needs based on terrestrial experience has been made. These needs fall into three broad categories: survival, self sufficiency, and industrialization. The cost of delivering payloads to orbital locations from LEO to Mars has been determined and future launch cost reductions projected. From these factors, then, projections of the performance necessary for future solar and nuclear space power options has been made. These goals are largely dependent upon orbital location and energy storage needs. Finally the cost of present space power systems has been determined and projections made for future systems.

    The renewed emphasis on robotic and human missions within NASA's space exploration program warrants a detailed consideration of how the positions of objects in space will be determined and tracked, whether they be spacecraft, human explorers, robots, surface vehicles, or science instrumentation. The Navigation Team within the NASA Space Communications Architecture Working Group (SCAWG) has addressed several key technical issues in this area and the principle findings are reported here. For navigation in the vicinity of the Moon, a variety of satellite constellations have been investigated that provide global or regional surface position determination and timely services analogous to those offered by GPS at Earth. In the vicinity of Mars, there are options for satellite constellations not available at the Moon due to the gravitational perturbations from Earth, such as two satellites in an aerostationary orbit. Alternate methods of radiometric navigation as considered, including one- and two-way signals, as well as autonomous navigation. The use of a software radio capable of receiving all available signal sources, such as GPS, pseudolites, and communication channels, is discussed. Methods of time transfer and dissemination are also considered in this paper.

  11. Compensation for environmental asbestos-related diseases in South Africa: a neglected issue

    PubMed Central

    Ndlovu, Ntombizodwa; Naude, Jim teWater; Murray, Jill

    2013-01-01

    Background Environmentally acquired asbestos-related diseases (ARDs) are of concern globally. In South Africa, there is widespread contamination of the environment due to historical asbestos mining operations that were poorly regulated. Although the law makes provision for the compensation of occupationally acquired ARDs, compensation for environmentally acquired ARDs is only available through the Asbestos Relief Trust (ART) and Kgalagadi Relief Trust, both of which are administered by the ART. This study assessed ARDs and compensation outcomes of environmental claims submitted to the Trusts. Methods The personal details, medical diagnoses, and exposure information of all environmental claims considered by the Trusts from their inception in 2003 to April 2010 were used to calculate the numbers and proportions of ARDs and compensation awards. Results There were 146 environmental claimants of whom 35 (23.9%) had fibrotic pleural disease, 1 (0.7%) had lung cancer, and 77 (52.7%) had malignant mesothelioma. 53 (36.3%) claimants were compensated: 20 with fibrotic pleural disease and 33 with mesothelioma. Of the 93 (63.7%) claimants who were not compensated, 33 had no ARDs, 18 had fibrotic pleural disease, 1 had lung cancer, and 44 had mesothelioma. In addition to having ARDs, those that were compensated had qualifying domestic (33; 62.2%) or neighbourhood (20; 37.8%) exposures to asbestos. Most of the claimants who were not compensated had ARDs but their exposures did not meet the Trusts’ exposure criteria. Conclusions This study demonstrates the environmental impact of asbestos mining on the burden of ARDs. Mesothelioma was the most common disease diagnosed, but most cases were not compensated. This highlights that there is little redress for individuals with environmentally acquired ARDs in South Africa. To stop this ARD epidemic, there is a need for the rehabilitation of abandoned asbestos mines and the environment. These issues may not be unique to South Africa as

    2014-12-01

    Geographic Information Systems (GIS) offer a plethora of applications for numerous fields, from geological sciences to urban planning. Therefore, developing a practical GIS curriculum for students from a diverse selection of majors can be challenging, especially since time constraints presented by the course term limit the number of projects that can cater to each student's academic focus. However, open ended assignments that allow students the freedom to personalize their projects present an opportunity to teach the universal functionality of GIS, as well as stimulate curiosity of students from all backgrounds by allowing them to tailor a project to their personal interests. During an introductory GIS course at the University of California, San Diego, projects prompted students to utilize ArcGIS in ways of their choice that raised awareness of local environmental issues, as well as encouraged students to incorporate environmentally sustainable practices into their lives. In view of the frequently stated interest of students to enter careers where they can use their newly learned GIS skills, the educational platform of choice is ESRI's ArcGIS, but the choice of platform remains flexible. As GIS resources become more accessible with the development of programs such as OpenGIS and OpenStreetMap, the potential for GIS to effectively communicate environmental issues to the public is growing fast. Incorporating these environmental issues into a curriculum not only allows students to personalize their education, but also raises awareness of such problems and provides students with the ability to communicate those issues using GIS.

  15. Key issues in transplant tourism.

    Akoh, Jacob A

    2012-02-24

    Access to organ transplantation depends on national circumstances, and is partly determined by the cost of health care, availability of transplant services, the level of technical capacity and the availability of organs. Commercial transplantation is estimated to account for 5%-10% (3500-7000) of kidney transplants performed annually throughout the world. This review is to determine the state and outcome of renal transplantation associated with transplant tourism (TT) and the key challenges with such transplantation. The stakeholders of commercial transplantation include: patients on the waiting lists in developed countries or not on any list in developing countries; dialysis funding bodies; middlemen, hosting transplant centres; organ-exporting countries; and organ vendors. TT and commercial kidney transplants are associated with a high incidence of surgical complications, acute rejection and invasive infection which cause major morbidity and mortality. There are ethical and medical concerns regarding the management of recipients of organs from vendors. The growing demand for transplantation, the perceived failure of altruistic donation in providing enough organs has led to calls for a legalised market in organ procurement or regulated trial in incentives for donation. Developing transplant services worldwide has many benefits - improving results of transplantation as they would be performed legally, increasing the donor pool and making TT unnecessary. Meanwhile there is a need to re-examine intrinsic attitudes to TT bearing in mind the cultural and economic realities of globalisation. Perhaps the World Health Organization in conjunction with The Transplantation Society would set up a working party of stakeholders to study this matter in greater detail and make recommendations.

    van Audenhove, Leo

    1998-09-01

    The term linkage is used to indicate co-operation between an institution in the North and an institution in the South. Donor organisations have generally used linkages to support the development of higher education and research in developing countries. Over time, there has been a trend away from co-operation on individual academic projects towards broader development co- operation and concentration on selected institutions. This shift raises questions about organisation, procedures and support mechanisms, and about the mandate and capabilities of universities in the North, given the frequently asymmetrical relationship between Northern institutions with their own research agendas and Southern beneficiaries. The recent restructuring of Canadian, Dutch, Norwegian and Swedish support for higher education and research is the result of a search for new, more appropriate models of co-operation. This paper examines the evolution of key issues of policy and organisation within the international donor community.

    Sand and gravel are widely used throughout the U.S. construction industry, but their extraction can significantly affect the physical, chemical, and biological characteristics of mined streams. Fisheries biologists often find themselves involved in the complex environmental and regulatory issues related to instream sand and gravel mining. This paper provides an overview of information presented in a symposium held at the 1997 midyear meeting of the Southern Division of the American Fisheries Society in San Antonio, Texas, to discuss environmental issues and regulatory procedures related to instream mining. Conclusions from the symposium suggest that complex physicochemical and biotic responses to disturbance such as channel incision and alteration of riparian vegetation ultimately determine the effects of instream mining. An understanding of geomorphic processes can provide insight into the effects of mining operations on stream function, and multidisciplinary empirical studies are needed to determine the relative effects of mining versus other natural and human-induced stream alterations. Mining regulations often result in a confusing regulatory process complicated, for example, by the role of the U.S. Army Corps of Engineers, which has undergone numerous changes and remains unclear. Dialogue among scientists, miners, and regulators can provide an important first step toward developing a plan that integrates biology and politics to protect aquatic resources.

    In Northern China, karst systems in widely distributed carbonate rocks are one of the most important water supplies for local inhabitants. Constrained by the specific geological and geomorphological conditions, most karst water in this region is discharged as individual or groups of springs. This paper summarizes the characteristics, chemistry, and environmental quality of these karst systems in Northern China. Five structural models of karst water systems were identified based on the relationships between the karst geological strata and karst groundwater flow fields. These specific structural models may closely relate to the attendant environmental geological issues and consistent risks from pollution. Over the past 40 years, the karst water systems in Northern China have suffered from various environmental problems, including deteriorating water quality, the drying up of springs, a continuous decline in the level of karst water, and so on. Based on the field investigation and previous data, a preliminary summary is provided of the environmental problems related to the development and evolutionary trends of karst water in this region. The results highlight the significant challenges associated with karst water, and it is essential that all segments of society be made aware of the situation in order to demand change. In addition, the study provides a scientific basis for the management, protection, and sustainable utilization of karst water resources.

    being in the context of global, national and regional stewardship. These societal needs lead to a vision that uses a regional framework as a stepping-stone to a comprehensive national or global capability. The development of a comprehensive regional framework depends on a new approach to environmental research - the creation of regional Environmental Intelligence Centers. A key objective is to bring a demanding level of discipline to "forecasting" in a broad arena of environmental issues. The regional vision described above is designed to address a broad range of current and future environmental issues by creating a capability based on integrating diverse observing systems, making data readily accessible, developing an increasingly comprehensive predictive capability at the spatial and temporal scales appropriate for examining societal issues, and creating a vigorous intersection with decision-makers. With demonstrated success over a few large-scale regions of the U.S., this strategy will very likely grow into a national capability that far exceeds current capabilities.

    Rural populations in the United States have lower physical activity levels and are at a higher risk of being overweight and suffering from obesity than their urban counterparts. This paper aimed to understand the environmental factors that influence physical activity among rural adults in Montana. Eight built environment audits, 15 resident focus groups, and 24 key informant interviews were conducted between August and December 2014. Themes were triangulated and summarized into five categories of environmental factors: built, social, organizational, policy, and natural environments. Although the existence of active living features was documented by environmental audits, residents and key informants agreed that additional indoor recreation facilities and more well-maintained and conveniently located options were needed. Residents and key informants also agreed on the importance of age-specific, well-promoted, and structured physical activity programs, offered in socially supportive environments, as facilitators to physical activity. Key informants, however, noted that funding constraints and limited political will were barriers to developing these opportunities. Since building new recreational facilities and structures to support active transportation pose resource challenges, especially for rural communities, our results suggest that enhancing existing features, making small improvements, and involving stakeholders in the city planning process would be more fruitful to build momentum towards larger changes.

  12. Neuropathological biomarker candidates in brain tumors: key issues for translational efficiency.

    PubMed

    Hainfellner, J A; Heinzl, H

    2010-01-01

    Brain tumors comprise a large spectrum of rare malignancies in children and adults that are often associated with severe neurological symptoms and fatal outcome. Neuropathological tumor typing provides both prognostic and predictive tissue information which is the basis for optimal postoperative patient management and therapy. Molecular biomarkers may extend and refine prognostic and predictive information in a brain tumor case, providing more individualized and optimized treatment options. In the recent past a few neuropathological brain tumor biomarkers have translated smoothly into clinical use whereas many candidates show protracted translation. We investigated the causes of protracted translation of candidate brain tumor biomarkers. Considering the research environment from personal, social and systemic perspectives we identified eight determinants of translational success: methodology, funding, statistics, organization, phases of research, cooperation, self-reflection, and scientific progeny. Smoothly translating biomarkers are associated with low degrees of translational complexity whereas biomarkers with protracted translation are associated with high degrees. Key issues for translational efficiency of neuropathological brain tumor biomarker research seem to be related to (i) the strict orientation to the mission of medical research, that is the improval of medical practice as primordial purpose of research, (ii) definition of research priorities according to clinical needs, and (iii) absorption of translational complexities by means of operatively beneficial standards. To this end, concrete actions should comprise adequate scientific education of young investigators, and shaping of integrative diagnostics and therapy research both on the local level and the level of influential international brain tumor research platforms.

  13. The Earth's radiation belts modelling : main issues and key directions for improvement

    NASA Astrophysics Data System (ADS)

    Maget, Vincent; Boscher, Daniel

    The Earth's radiation belts can be considered as an opened system covering a wide part of the inner magnetosphere which closely interacts with the surrounding cold plasma. Although its population constitutes only the highly energetic tail of the global inner magnetosphere plasma (electrons from a few tens of keV to more than 5 MeV and protons up to 500MeV), their modelling is of prime importance for satellite robustness design. They have been modelled at ONERA for more than 15 years now through the Salammbˆ code, which models the dynamic of the Earth's radiation belts at the drift timescale (order of the hour). It takes into accounts the main processes acting on the trapped particles, which depends on the electromagnetic configuration and on the characteristics of the surrounding cold plasma : the ionosphere as losses terms, the plasmasheet as sources ones and the plasmasphere through interactions (waves-particles interactions, coulomb scattering, electric fields shielding, . . . ). Consequently, a fine knowledge of these environments and their interactions with the radiation belts is of prime importance in their modelling. Issues in the modelling currently exist, but key directions for improvements can also be highlighted. This talk aims at presenting both of them according to recent developments performed at ONERA besides the Salammbˆ code. o

    Minerals in the environment and products manufactured from mineral materials are all around us and we use and come into contact with them every day. They impact our way of life and the health of all that lives. Minerals are critical to the Nation's economy and knowing where future mineral resources will come from is important for sustaining the Nation's economy and national security. The U.S. Geological Survey (USGS) Mineral Resources Program (MRP) provides scientific information for objective resource assessments and unbiased research results on mineral resource potential, production and consumption statistics, as well as environmental consequences of mining. The MRP conducts this research to provide information needed for land planners and decisionmakers about where mineral commodities are known and suspected in the earth's crust and about the environmental consequences of extracting those commodities. As part of the MRP scientists of the Western Mineral and Environmental Resources Science Center (WMERSC or 'Center' herein) coordinate the development of national, geologic, geochemical, geophysical, and mineral-resource databases and the migration of existing databases to standard models and formats that are available to both internal and external users. The unique expertise developed by Center scientists over many decades in response to mineral-resource-related issues is now in great demand to support applications such as public health research and remediation of environmental hazards that result from mining and mining-related activities. Western Mineral and Environmental Resources Science Center Results of WMERSC research provide timely and unbiased analyses of minerals and inorganic materials to (1) improve stewardship of public lands and resources; (2) support national and international economic and security policies; (3) sustain prosperity and improve our quality of life; and (4) protect and improve public health, safety, and environmental quality.

    2005-11-01

    Students and citizens need to apply science to important issues every day. Yet the design of science curricula that foster integration of science and everyday decisions is not well understood. For example, can curricula be designed that help learners apply scientific reasons for choosing only environmentally sustainable seafood for dinner? Learners must develop integrated understandings of scientific principles, prior experiences, and current decisions in order to comprehend how everyday decisions impact environmental resources. In order to investigate how such integrated understandings can be promoted within school science classes, research was conducted with an inquiry-oriented curriculum that utilizes technology and a visit to an informal learning environment (aquarium) to promote the integration of scientific principles (adaptation) with environmental stewardship. This research used a knowledge integration approach to teaching and learning that provided a framework for promoting the application of science to environmental issues. Marine biology, often forsaken in classrooms for terrestrial biology, served as the scientific context for the curriculum. The curriculum design incorporated a three-phase pedagogical strategy and new technology tools to help students integrate knowledge and experiences across the classroom and aquarium learning environments. The research design and assessment protocols included comparisons among and within student populations using two versions of the curriculum: an issue-based version and a principle-based version. These inquiry curricula were tested with sophomore biology students attending a marine-focused academy within a coastal California high school. Pretest-posttest outcomes were compared between and within the curricular treatments. Additionally, comparisons were made between the inquiry groups and seniors in an Advanced Placement biology course who attend the same high school. Results indicate that the inquiry curricula

    The UC Berkeley East Bay Academy for Young Scientists (EBAYS) program provides youth from non-dominant communities in the East San Francisco Bay Area with unique opportunities to develop deeper understanding of environmental science content, as well as fundamental scientific practice skills. A key component of EBAYS programming is collaborative research projects that generate information useful in addressing critical environmental issues. This important component also provides opportunities for youth to present results of their investigations to other community members and to the scientific community at large. Inclusion of the environmental science research component is intended to help address the following program goals: A) increasing appreciation for the value of scientific practices as a tool for addressing important community-based issues; B) helping raise community awareness of important issues; C) sparking interest in other forms of community activism; D) increasing understanding of key science concepts; and E) generating valuable environmental quality data. In an effort to assess the degree to which EBAYS programming accomplishes these goals, as well as to evaluate its capacity to be effectively replicated on a broader scale, EBAYS staff has engaged in an investigation of associated learning and youth development outcomes. In this regard a research strategy has been developed that includes the use of assessment tools that will help foster a deeper understanding of the ways in which EBAYS programming increases the extent to which participants value the application of science, affects their overall occupational trajectory, and inspires them to consider careers in STEM.

    Education for Sustainability has become an institutional requirement in many countries. It takes many forms that can integrate the teaching of environmental Socioscientific Issues (SSIs). In this context, we present the French notion of Socially Acute Questions (SAQs). We develop a theoretical frame to analyse educational configurations applied to the teaching of SAQs within the perspective of sustainability. This frame is built with a reference to a matrix integrating attributes of knowledge (universal, plural, engaged or contextualised), teachers' epistemological postures (scientism, utilitarianism, skepticsm or relativism) and various didactic strategies (doctrinal, problematizing, critical or pragmatic). To illustrate this frame, three situations of teaching-learning are compared.

    Seal, Robert R.; Nordstrom, D. Kirk

    2015-01-01

    Environmental geochemistry is an integral part of the mine-life cycle, particularly for modern mining. The critical importance of environmental geochemistry begins with pre-mining baseline characterization and the assessment of environmental risks related to mining, continues through active mining especially in water and waste management practices, and culminates in mine closure. The enhanced significance of environmental geochemistry to modern mining has arisen from an increased knowledge of the impacts that historical and active mining can have on the environment, and from new regulations meant to guard against these impacts. New regulations are commonly motivated by advances in the scientific understanding of the environmental impacts of past mining. The impacts can be physical, chemical, and biological in nature. The physical challenges typically fall within the purview of engineers, whereas the chemical and biological challenges typically require a multidisciplinary array of expertise including geologists, geochemists, hydrologists, microbiologists, and biologists. The modern mine-permitting process throughout most of the world now requires that potential risks be assessed prior to the start of mining. The strategies for this risk assessment include a thorough characterization of pre-mining baseline conditions and the identification of risks specifically related to the manner in which the ore will be mined and processed, how water and waste products will be managed, and what the final configuration of the post-mining landscape will be.In the Fall 2010, the Society of Economic Geologists held a short course in conjunction with the annual meeting of the Geological Society of America in Denver, Colorado (USA) to examine the environmental geochemistry of modern mining. The intent was to focus on issues that are pertinent to current and future mines, as opposed to abandoned mines, which have been the focus of numerous previous short courses. The geochemical

    This paper proposes a set of web-based indicators for quantifying and ranking the relevance of terms related to key-issues in Ecology and Sustainability Science. Search engines that operate in different contexts (e.g. global, social, scientific) are considered as web information carriers (WICs) and are able to analyse; (i) relevance on different levels: global web, individual/personal sphere, on-line news, and culture/science; (ii) time trends of relevance; (iii) relevance of keywords for environmental governance. For the purposes of this study, several indicators and specific indices (relational indices and dynamic indices) were applied to a test-set of 24 keywords. Outputs consistently show that traditional study topics in environmental sciences such as water and air have remained the most quantitatively relevant keywords, while interest in systemic issues (i.e. ecosystem and landscape) has grown over the last 20 years. Nowadays, the relevance of new concepts such as resilience and ecosystem services is increasing, but the actual ability of these concepts to influence environmental governance needs to be further studied and understood. The proposed approach, which is based on intuitive and easily replicable procedures, can support the decision-making processes related to environmental governance. PMID:22905118

    Kwon, Soonman

    2011-09-01

    This article examines the major elements of health care financing such as financial risk protection, resource generation, resource pooling, and purchasing and payment; provides key lessons; and discusses the challenges for health care financing systems of Asian countries. With the exception of Japan, Korea, Taiwan, and Thailand, most health care systems of Asia provide very limited financial risk protection. The role of public prepaid schemes such as tax and social health insurance is minimal, and out-of-pocket payment is a major source of financing. The large informal sector is a major challenge to the extension of population coverage in many low-income countries of Asia, which must seek the optimal mix of tax subsidy and health insurance for universal coverage. Implementation of effective payment systems to control the behavior of health care providers is also a key factor in the success of health care financing reform in Asia.

    2015-01-15

    One of the major difficulties in water planning is to determine the water availability in a water resource system in order to distribute water sustainably. In this paper, we analyze the key issues for determining the exploitable water resources as an indicator of water availability in a Mediterranean river basin. Historically, these territories are characterized by heavily regulated water resources and the extensive use of unconventional resources (desalination and wastewater reuse); hence, emulating the hydrological cycle is not enough. This analysis considers the Jucar River Basin as a case study. We have analyzed the different possible combinations between the streamflow time series, the length of the simulation period and the reliability criteria. As expected, the results show a wide dispersion, proving the great influence of the reliability criteria used for the quantification and localization of the exploitable water resources in the system. Therefore, it is considered risky to provide a single value to represent the water availability in the Jucar water resource system. In this sense, it is necessary that policymakers and stakeholders make a decision about the methodology used to determine the exploitable water resources in a river basin.

  9. Environmental changes and violent conflict

    Bernauer, Thomas; Böhmelt, Tobias; Koubi, Vally

    2012-03-01

    This letter reviews the scientific literature on whether and how environmental changes affect the risk of violent conflict. The available evidence from qualitative case studies indicates that environmental stress can contribute to violent conflict in some specific cases. Results from quantitative large-N studies, however, strongly suggest that we should be careful in drawing general conclusions. Those large-N studies that we regard as the most sophisticated ones obtain results that are not robust to alternative model specifications and, thus, have been debated. This suggests that environmental changes may, under specific circumstances, increase the risk of violent conflict, but not necessarily in a systematic way and unconditionally. Hence there is, to date, no scientific consensus on the impact of environmental changes on violent conflict. This letter also highlights the most important challenges for further research on the subject. One of the key issues is that the effects of environmental changes on violent conflict are likely to be contingent on a set of economic and political conditions that determine adaptation capacity. In the authors' view, the most important indirect effects are likely to lead from environmental changes via economic performance and migration to violent conflict.

    The emergence of complex and fascinating states of quantum matter in the neighborhood of zero temperature phase transitions suggests that such quantum phenomena should be studied in a variety of settings. Advanced technologies of the future may be fabricated from materials where the cooperative behavior of charge, spin and current can be manipulated at cryogenic temperatures. The progagating lattice dynamics of displacive ferroelectrics make them appealing for the study of quantum critical phenomena that is characterized by both space- and time-dependent quantities. In this key issues article we aim to provide a self-contained overview of ferroelectrics near quantum phase transitions. Unlike most magnetic cases, the ferroelectric quantum critical point can be tuned experimentally to reside at, above or below its upper critical dimension; this feature allows for detailed interplay between experiment and theory using both scaling and self-consistent field models. Empirically the sensitivity of the ferroelectric T c 's to external and to chemical pressure gives practical access to a broad range of temperature behavior over several hundreds of Kelvin. Additional degrees of freedom like charge and spin can be added and characterized systematically. Satellite memories, electrocaloric cooling and low-loss phased-array radar are among possible applications of low-temperature ferroelectrics. We end with open questions for future research that include textured polarization states and unusual forms of superconductivity that remain to be understood theoretically.

    2011-01-01

    Background: Alongside the major health risks posed by environmental pollution in China are recent achievements on several environmental issues that have affluent Western nations racing to catch up. The country has propelled itself to a position of leadership in clean energy and efficiency, for instance, with important consequences for public health. Objectives: We comment on China’s challenges and recent accomplishments in addressing environmental problems from domestic pollution to global climate change. We compare China’s commitment to clean energy technology with that of other leading nations and discuss key achievements in other areas, including vehicle efficiency standards and transportation policy. Discussion: We discuss policy directions that would secure much-needed improvements to environmental quality and health in China, along with actions that could motivate global action on issues of energy conservation and pollution reduction. Conclusions: A comprehensive regulatory and institutional framework for environmental policy is within reach in China but will require addressing major hurdles such as the lack of an independent monitoring mechanism and the need for greater transparency and enforcement in environmental matters. Meanwhile, China can continue to set important examples by investing in renewable energy, improving energy efficiency, and limiting greenhouse gas emissions. PMID:21402514

  14. Approaches and incentives to implement integrated pest management that addresses regional and environmental issues.

    Brewer, Michael J; Goodell, Peter B

    2012-01-01

    Agricultural, environmental, and social and policy interests have influenced integrated pest management (IPM) from its inception. The first 50 years of IPM paid special attention to field-based management and market-driven decision making. Concurrently, IPM strategies became available that were best applied both within and beyond the bounds of individual fields and that also provided environmental benefits. This generated an incentives dilemma for farmers: selecting IPM activities for individual fields on the basis of market-based economics versus selecting IPM activities best applied regionally that have longer-term benefits, including environmental benefits, that accrue to the broader community as well as the farmer. Over the past several decades, public-supported incentives, such as financial incentives available to farmers from conservation programs for farms, have begun to be employed to encourage use of conservation techniques, including strategies with IPM relevance. Combining private investments with public support may effectively address the incentives dilemma when advanced IPM strategies are used regionally and provide public goods such as those benefiting resource conservation. This review focuses on adaptation of IPM to these broader issues, on transitions of IPM from primarily individual field-based decision making to coordinated community decision making, and on the form of partnerships needed to gain long-lasting regional and environmental benefits.

    The aim of the present study was to explore key genes that may have a role in the pathology of measles virus infection and to clarify the interaction networks between environmental factors and differentially expressed genes (DEGs). After screening the database of the Gene Expression Omnibus of the National Center for Biotechnology Information, the dataset GSE5808 was downloaded and analyzed. A global normalization method was performed to minimize data inconsistencies and heterogeneity. DEGs during different stages of measles virus infection were explored using R software (v3.4.0). Gene Ontology and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis of the DEGs were performed using Cytoscape 3.4.0 software. A protein-protein interaction (PPI) network of the DEGs was obtained from the STRING database v9.05. A total of 43 DEGs were obtained from four analyzed sample groups, including 10 highly expressed genes and 33 genes with decreased expression. The most enriched pathways based on KEGG analysis were fatty acid elongation, cytokine-cytokine receptor interaction and RNA degradation. The genes mentioned in the PPI network were mainly associated with protein binding and chemokine activity. A total of 219 chemicals were identified that may, jointly or on their own, interact with the 6 DEGs between the control group and patients with measles (at hospital entry), including benzo(a)pyrene (BaP) and tetrachlorodibenzodioxin (TCDD). In conclusion, the present study revealed that chemokines and environmental chemicals, e.g. BaP and TCDD, may affect the development of measles. PMID:29805511

    The Bonneville Power Administration (Bonneville) has identified 101 plants in the Pacific Northwest that account for 80% of the region's industrial electricity consumption. These plants offer a precise target for a conservation program. PNL determined that most of these 101 plants were represented by 11 major industries. We then reviewed 36 major conservation technologies used in these 11 industrial settings to determine their potential environmental impacts. Energy efficiency technologies designed for industrial use may result in direct or indirect environmental impacts. Effects may result from the production of the conservation measure technology, changes in the working environment due to differentmore » energy and material requirements, or changes to waste streams. Industry type, work-place conditions, worker training, and environmental conditions inside and outside the plant are all key variables that may affect environmental outcomes. To address these issues this report has three objectives: Describe potential conservation measures that Bonneville may employ in industrial programs and discuss potential primary impacts. Characterize industrial systems and processes where the measure may be employed and describe general environmental issues associated with each industry type. Review environmental permitting, licensing, and other regulatory actions required for industries and summarize the type of information available from these sources for further analysis.« less

  4. The Environmental Dimensions of Migration

    2017-01-01

    Research on the environmental dimensions of human migration has made important strides in recent years. However, findings have been spread across multiple disciplines with wide ranging methodologies and limited theoretical development. This article reviews key findings of the field and identifies future directions for sociological research. We contend that the field has moved beyond linear environmental “push” theories towards a greater integration of context, including micro-, meso-, and macro-level interactions. We highlight findings that migration is often a household strategy to diversify risk (NELM), interacting with household composition, individual characteristics, social networks, and historical, political and economic contexts. We highlight promising developments in the field, including the recognition that migration is a long-standing form of environmental adaptation and yet only one among many forms of adaptation. Finally, we argue that sociologists could contribute significantly to migration-environment inquiry through attention to issues of inequality, perceptions, and agency vis-à-vis structure.

  5. Environmental and energy issues in an open economy

    NASA Astrophysics Data System (ADS)

    Oh, Kyungsoo

    The environmental and energy consequences of globalization have become an important topic of debate. My dissertation examines the interaction between environmental and energy issues and international trade. Specifically, I investigate environmental regulations and policy in an open economy. In the first chapter, I analyze how an environmental tax on pollution from consumption affects trade flows and welfare in an open economy. In particular, I argue that the effect of an environmental tax on the direction of trade flows depends on who is directly burdened by the regulation (consumers or producers) regardless of who is the polluter. In the case of pollution generated by consumers, a tax on consumers who are the polluters tends to increase exports and reduce imports of dirty goods. This result is the opposite of the well-known effect arising from taxes on pollution-intensive industries. Stringent environmental regulations on pollution-intensive industries diminishes exports and increases imports of dirty industries. In terms of welfare, I show the importance of targeting the policy instrument to the correct source of pollution. Assuming pollution is caused by the consumption of a good, a production tax has a weak effect on increasing welfare through reducing pollution. Furthermore, welfare can fall if the production tax ratio is too high, leading to reduced national income. The second chapter is motivated by recent trends in the U.S. economy: increasing imports from China, decreasing energy consumption, and increasing output. There are two primary theoretical approaches related to the relationship between energy use in U.S. manufacturing and increasing imports from China: Heckscher-Ohlin (H-O) trade theory and the Pollution Haven Hypothesis (PHH). These two frameworks generate opposite predictions about the relationship between these trends. H-O theory suggests that with increased Chinese import penetration, U.S. manufacturing should move toward more energy

    In February 1994, the Environmental Bill of Rights, 1993 (EBR) was proclaimed into law by the Ontario government. The EBR is intended to promote a new era in environmental decision-making one characterized by enhanced public participation, citizen empowerment and greater accountability of decision makers. A key challenge in the implementation of the EBR is the change it will force in government decision-making. Historically, Ontario environmental regulation focused on the development of appropriate pollution control instruments, techniques and standards to control harmful environmental activity. Often the knowledge of outsiders, (i.e. the public), was considered inadequate or irrelevant to the regulatory process.more » In contrast, the EBR recognizes the relevance and validity of public knowledge, and is intended to encourage decision-makers to mesh public and scientific knowledge through a new regulatory approval system based on notice of new developments, approvals and laws on a province-wide electronic bulletin board service. The positive potential of the EBR is in its ability to promote social understanding of the issues and risks in environmental management. The EBR mandates open dialogue and proactive interaction between government, industry, environmental groups, citizen groups, and employees to explore new mechanisms in environmental decision making. In addition, the EBR seeks to enlist the cooperation of all sectors of society in addressing the complex issues posed by the environment so that not only problem solving but problem identification and prevention activities are conducted in the context of greater shared responsibility and accountability.« less

    Risk analysis of key systems have become a growing topic late of because of the development of offshore structures. Equipment failures of offloading system and fire accidents were analyzed based on the floating production, storage and offloading (FPSO) features. Fault tree analysis (FTA), and failure modes and effects analysis (FMEA) methods were examined based on information already researched on modules of relex reliability studio (RRS). Equipment failures were also analyzed qualitatively by establishing a fault tree and Boolean structure function based on the shortage of failure cases, statistical data, and risk control measures examined. Failure modes of fire accident were classified according to the different areas of fire occurrences during the FMEA process, using risk priority number (RPN) methods to evaluate their severity rank. The qualitative analysis of FTA gave the basic insight of forming the failure modes of FPSO offloading, and the fire FMEA gave the priorities and suggested processes. The research has practical importance for the security analysis problems of FPSO.

    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.

    Obesity is a serious, chronic medical condition which is associated with a wide range of debilitating and life-threatening conditions. It imposes huge financial burdens on health care systems and the community at large. Obesity develops over time and once it has done so, is difficult to treat. Therefore, the prevention of weight gain offers the only truly effective means of controlling obesity. Very little research has directly addressed the issue of obesity prevention and previous efforts to prevent obesity amongst individuals, groups or whole communities have had very limited success. However, we have learned sufficient from past preventive activities to realise that the management of obesity will require a comprehensive range of strategies with actions that target those with existing weight problems, those at high risk of developing obesity as well as the community as a whole. The prevention and management of obesity in children should be considered a priority as there is a high risk of persistence into adulthood.

    Evaluation in environmental education is fairly nascent despite decades-long attention to its importance. In setting the context for future chapters appearing in this special issue of the Journal of Evaluation and Program Planning, attention is devoted to the political circumstances associated with retrenchment in the public sector and increased involvement of citizens in environmental issues in their regions. It further is nested in the context of potential political reforms in a stable market democracy where education is but one strategy that can be bundled with regulations and taxes/subsidies. Additional attention is directed to explaining many of the key evaluation theories--utilization-focused evaluation, evaluative capacity building, and program-theory driven evaluation. The final section of this chapter situates the subsequent chapters of this volume based on the demographic target (youth or adult) as well as connection to a particular evaluation theory.

    In a research project about work-related issues and corporate sustainability conducted in Brazil, the goal was to better understand how work-related issues were addressed in the corporate context. Particularly, there are some specific initiatives that serve as guides to organizational decisions, which make their performance indicators for the context of corporate sustainability. 1) To explore the presence of work-related issues and their origins in corporate sustainability approach, analyzing a) corporate disclosures; b) sustainability guidelines that are identified as relevant in corporate disclosures; c) documents that are related to sustainable development and also identified as key-documents for these guidelines and initiatives. 2) To present the activity-centered ergonomics and psychodynamics of work contributions to work-related issues in a corporate sustainability approach. An exploratory study based on multiple sources of evidence that were performed from 2012 to 2013, including interviews with companies that engaged in corporate sustainability and document analysis using the content analysis approach. Work-related issues have been presented since the earliest sustainable development documents. It is feasible to construct an empirical framework for work-related issues and corporate sustainability approaches. 1) Although some authors argue that corporate sustainability has its roots based only on the environmental dimension, there is strong empirical evidence showing that social dimension aspects such as work-related issues have been present since the beginning. 2) Some indicators should be redesigned to more precisely translate the reality of some workplaces, particularly those indicators related to organizational design and mental health.

    2017-03-01

    Guided by sociocultural perspectives on the importance of place as a resource for learning, we investigated 14- and 15-year old students' understandings of their community and water quality during a school-based watershed unit. Methods included a theory-driven thematic analysis of field notes and video transcripts from four biology classrooms, a qualitative and quantitative analysis of 67 pairs of matched pre- and post-intervention mindmaps, and a content analysis of 73 student reflections. As they learned about water quality, learners recognized the relevance of the watershed's health to the health of their community. Students acknowledged the impacts of local economically driven activities (e.g., natural gas wells, application of agrichemicals) and leisure activities (e.g., boating, fishing) on the watershed's environmental health. As students learned in and about their watershed, they experienced both connections and tensions between their everyday experiences and the environmental problems in their community. The students suggested individual sustainability actions needed to address water quality issues; however, the students struggled to understand how to act collectively. Implications of rural experiences as assets to future environmental sciences learning are discussed as well as the implications of educational experiences that do not include an advocacy component when students uncover environmental health issues. We suggest further consideration is needed on how to help young people develop action-oriented science knowledge, not just inert knowledge of environmental problems, during place-based education units.

    As global climate change becomes more evident, demand will likely increase for experts with a detailed understanding of the scientific basis of climate change, the ocean's role in the earth-atmosphere system, and forecasted impacts, especially in Arctic regions where effects may be most pronounced. As a result, programs in marine and environmental sciences are uniquely poised to prepare graduates for the formidable challenges posed by changing climates. Here we present research evaluating the prevalence and themes of courses focusing on anthropogenic climate change in 125 Marine Science and Environmental Science undergraduate programs at 86 institutions in the United States. These results, in addition to the increasing role of the Coast Guard in the Arctic, led to the development of two new courses in the curriculum. Climate Change Science, a one-credit seminar, includes several student-centered activities supporting key learning objectives. Polar Oceanography, a three-credit course, incorporates a major outreach component to Coast Guard units and members of the scientific community. Given the importance of climate change in Arctic regions in particular, we also propose six essential "Arctic Literacy Principles" around which courses or individual lesson plans may be organized. We show how these principles are incorporated into an additional new three-credit course, Model Arctic Council, which prepares students to participate in a week-long simulation exercise of Arctic Council meetings, held in Fairbanks, Alaska. Students examine the history and mission of the Arctic Council and explore some of the issues on which the council has deliberated. Special attention is paid to priorities of the current U.S. chairmanship of the Arctic Council which include climate change impacts on, and stewardship of, the Arctic Ocean.

    The objective of the comparative assessment is to provide an initial, traceable and consistent comparison of the SPS and selected current, near-term, and advanced energy technologies. Terrestrial alternatives were selected, and their cost, performance, and environmental and societal attributes were specified for use in the comparison with the SPS in the post-2000 era. The framework for comparisons was established. The SPS was compared with alternative systems in terms of key issues such as life-cycle cost and environmental impacts. The results of the assessments were assembled and integrated into a consistent comparative assessment. Environmental and economic effects are evaluated, which weremore » subdivided into the following issue areas: human health and safety, environmental welfare, resources (land, materials, energy, water, labor), macroeconomics, socioeconomics, and institutional. These evaluations were based on technology characterization data and alternative futures scenarios, which were developed as part of CDEP by supporting studies. The technologies and the scenarios are described. An additional major issue area concerned the cost and performance of the SPS and the alternative technologies: results in this area provided part of the basis of the macroeconomic analyses. 159 references.« less

  1. The Expanding Role of Traceability in Seafood: Tools and Key Initiatives.

    Lewis, Sara G; Boyle, Mariah

    2017-08-01

    In the last decade, a range of drivers within the seafood sector have incentivized the application of traceability to issues beyond food safety and inventory management. Some of the issues motivating the expanded use of traceability within the global seafood sector include: increased media attention on the legal and social risks within some seafood supply chains, governmental traceability requirements, private-sector sustainability commitments, and others. This article begins with an overview of these topics in the seafood industry, and why many nongovernment organizations (NGOs), companies, and government actors have turned to traceability as a tool to address them. We discuss how traceability connects to key requirements of environmental sustainability and social responsibility. Later, we review the range of traceability services, tools, software solutions, and the due diligence measures that are currently being leveraged within the seafood sector. The paper concludes with a discussion of several NGO- and industry-led traceability initiatives that are examples of seafood traceability improvements. © 2017 Institute of Food Technologists®.

The route toward these nano-objects is based primarily on electrospinning: a highly versatile method that allows the fabrication of continuous fibers with diameters down to a few nanometers. The mechanism responsible for the fiber formation mainly includes the Taylor Cone theory and flight-instability theory, which can be predicted theoretically and controlled experimentally. Moreover, the electrospinning has been applied to natural polymers, synthetic polymers, ceramics, and carbon. Fibers with complex architectures, such as ribbon fiber, porous fiber, core-shell fiber, or hollow fiber, can be produced by special electrospinning methods. It is also possible to produce nanofibrous membranes with designed aggregate structure including alignment, patterning, and two-dimensional nanonets. Finally, the brief analysis of nanofibers used for advanced energy and environmental applications in the past decade indicates that their impact has been realized well and is encouraging, and will continually represent a key technology to ensure sustainable energy and preserve our environment for the future.

    Investigations aimed at the study on the state of environment from the point of pollution by organochlorine pesticides and their metabolites (HCH, DDT, DDE and DDD), as well as on possible unfavorable impact due to carriage of mentioned persistent organic pollutants (POPs) towards reproductive health and cytogenetic status of organism were done. In parallel, monitoring of possible mutagenic components of the environment was also conducted. As to obtained data, residues of organochlorine pesticides are continually determined with high frequency both in environmental media, agricultural foodstuffs and biomedia of rural population of observed region (Aragatsotn marz, Armenia). No changes in mutagenic background were registered. The represented results of the study make fragment of complex social-hygienic, monitoring investigations on environmental quality that would further serve as a platform for working out the recommendations on reduction of environmental pollution and improvement of health protection issues in Armenia.

    This synthesis article joins the authors of the special issue "Gender perspectives in resilience, vulnerability and adaptation to global environmental change" in a common reflective dialogue about the main contributions of their papers. In sum, here we reflect on links between gender and feminist approaches to research in adaptation and resilience in global environmental change (GEC). The main theoretical contributions of this special issue are threefold: emphasizing the relevance of power relations in feminist political ecology, bringing the livelihood and intersectionality approaches into GEC, and linking resilience theories and critical feminist research. Empirical insights on key debates in GEC studies are also highlighted from the nine cases analysed, from Europe, the Americas, Asia, Africa and the Pacific. Further, the special issue also contributes to broaden the gender approach in adaptation to GEC by incorporating research sites in the Global North alongside sites from the Global South. This paper examines and compares the main approaches adopted (e.g. qualitative or mixed methods) and the methodological challenges that derive from intersectional perspectives. Finally, key messages for policy agendas and further research are drawn from the common reflection.

  7. Using Next Generation Science Standards (NGSS) Practices to Address Scientific Misunderstandings Around Complex Environmental Issues

    NASA Astrophysics Data System (ADS)

    Turrin, M.; Kenna, T. C.

    2014-12-01

    The new NGSS provide an important opportunity for scientists to develop curriculum that links the practice of science to research-based data in order to improve understanding in areas of science that are both complex and confusing. Our curriculum focuses in particular on the fate and transport of anthropogenic radionuclides. Radioactivity, both naturally occurring and anthropogenic, is highly debated and largely misunderstood, and for large sections of the population is a source of scientific misunderstanding. Developed as part of the international GEOTRACES project which focuses on identifying ocean processes and quantifying fluxes that control the distributions of selected trace elements and isotopes in the ocean, and on establishing the sensitivity of these distributions to changing environmental conditions, the curriculum topic fits nicely into the applied focus of NGSS with both environmental and topical relevance. Our curriculum design focuses on small group discussion driven by questions, yet unlike more traditional curriculum pieces these are not questions posed to the students, rather they are questions posed by the students to facilitate their deeper understanding. Our curriculum design challenges the traditional question/answer memorization approach to instruction as we strive to develop an educational approach that supports the practice of science as well as the NGSS Cross Cutting Concepts and the Science & Engineering Practices. Our goal is for students to develop a methodology they can employ when faced with a complex scientific issue. Through background readings and team discussions they identify what type of information is important for them to know and where to find a reliable source for that information. Framing their discovery around key questions such as "What type of radioactive decay are we dealing with?", "What is the potential half-life of the isotope?", and "What are the pathways of transport of radioactivity?" allows students to evaluate a

    The main goal of this special issue is to offer a room for interdisciplinary and engaged research in global environmental change (GEC), where gender plays a key role in building resilience and adaptation pathways. In this editorial paper, we explain the background setting, key questions and core approaches of gender and feminist research in vulnerability, resilience and adaptation to GEC. Highlighting the interlinkages between gender and GEC, we introduce the main contributions of the collection of 11 papers in this special issue. Nine empirical papers from around the globe allow to understand how gendered diversity in knowledge, institutions and everyday practices matters in producing barriers and options for achieving resilience and adaptive capacity in societies. Additionally, two papers contribute to the theoretical debate through a systematic review and an insight on the relevance of intersectional framings within GEC research and development programming.

    1998-11-01

    / This paper is a presentation of the problems of solid waste management in Nigeria and certain important issues that must be addressed in order to achieve success. At the core of the problems of solid waste management are the absence of adequate policies, enabling legislation, and an environmentally stimulated and enlightened public. Government policies on the environment are piecemeal where they exist and are poorly implemented. Public enlightenment programs lacked the needed coverage, intensity, and continuity to correct the apathetic public attitude towards the environment. Up to now the activities of the state environmental agencies have been hampered by poor funding, inadequate facilities and human resources, inappropriate technology, and an inequitable taxation system. Successful solid waste management in Nigeria will require a holistic program that will integrate all the technical, economic, social, cultural, and psychological factors that are often ignored in solid waste programs.KEY WORDS: Solid waste; Management; Problems; Solutions; Nigeria

    Background Management of environmental health issues is an integral part of public health systems. An active integrated environmental health surveillance and response system was developed for the Athens Olympics to monitor and prevent exposure to environmental hazards. The potential for permanent implementation of the program was examined. Methods The environmental health surveillance and response system included standardization, computerization and electronic transmission of data concerning environmental inspections of 17 site categories (restaurants, swimming pools etc) of public health interest, drinking and recreational water examinations and suggested corrective actions. The Olympic Planning Unit integrated and centrally managed data from 13 public health agencies, recommended, supervised and coordinated prompt corrective actions. Methods used to test the effectiveness of the program were the assessment of water quality test and inspection results trends over time using linear regression and epidemiological surveillance findings. Results Between January 2003 and September the 30th, 2004, 196 inspectors conducted 8562 inspections, collected 5024 water samples and recommended 17 027 corrective actions. In 10 cruise ships used as floating hotels inspectors conducted 10 full inspections, 2 re-inspections, and 27 follow-up inspections. Unsatisfactory inspection results (r = 0.44, p < 0.0001) and positive water quality tests (r = 0.39, p < 0.001) presented an overall decrease trend over time. In August, 2003, an outbreak of salmonellosis was linked to a hotel restaurant which accommodated athletes during a test event. Conclusion Lessons learned for future events include timely implementation and installation of communication processes, and rapid and coordinated response to unsatisfactory inspection results. Routine national programs need to adopt enhanced environmental health surveillance aimed at public health decision-making, but with a different perspective. PMID

    2012-06-01

    Statistics is an indispensible tool for evaluating treatment effects in clinical research. Due to the complexities of periodontal disease progression and data collection, statistical analyses for periodontal research have been a great challenge for both clinicians and statisticians. The aim of this article is to provide an overview of several basic, but important, statistical issues related to the evaluation of treatment effects and to clarify some common statistical misconceptions. Some of these issues are general, concerning many disciplines, and some are unique to periodontal research. We first discuss several statistical concepts that have sometimes been overlooked or misunderstood by periodontal researchers. For instance, decisions about whether to use the t-test or analysis of covariance, or whether to use parametric tests such as the t-test or its non-parametric counterpart, the Mann-Whitney U-test, have perplexed many periodontal researchers. We also describe more advanced methodological issues that have sometimes been overlooked by researchers. For instance, the phenomenon of regression to the mean is a fundamental issue to be considered when evaluating treatment effects, and collinearity amongst covariates is a conundrum that must be resolved when explaining and predicting treatment effects. Quick and easy solutions to these methodological and analytical issues are not always available in the literature, and careful statistical thinking is paramount when conducting useful and meaningful research. © 2012 John Wiley & Sons A/S.

    Large, multinational resource development projects can affect many aspects, including social, economic and ecological realities, in the regions where they operate. Social and environmental issues that are usually ignored in such projects are increasingly affecting the financial future of multinational corporations in negative ways. In this article, we advance the argument that corporations can successfully manage these issues and that if they choose to view these management efforts as an investment rather than an expense, they may well acquire a competitive advantage over companies that do not. We describe as a case study the Camisea natural gas and condensates development project in Peru, operated by Shell Prospecting and Development Peru (SPDP). Camisea is one of the first projects anywhere in the world to conduct a detailed analysis of key industry-related social issues and the processes, required investment and financial impact of managing them. The Camisea example supports the argument that addressing social and environmental concerns makes financial sense. In present value terms, the benefit of managing these concerns was expected to surpass the cost investment by approximately US$50 million.

    Abstract The scale and magnitude of complex and pressing environmental issues lend urgency to the need for integrative and reproducible analysis and synthesis, facilitated by data-intensive research approaches. However, the recent pace of technological change has been such that appropriate skills to accomplish data-intensive research are lacking among environmental scientists, who more than ever need greater access to training and mentorship in computational skills. Here, we provide a roadmap for raising data competencies of current and next-generation environmental researchers by describing the concepts and skills needed for effectively engaging with the heterogeneous, distributed, and rapidly growing volumes of available data. We articulate five key skills: (1) data management and processing, (2) analysis, (3) software skills for science, (4) visualization, and (5) communication methods for collaboration and dissemination. We provide an overview of the current suite of training initiatives available to environmental scientists and models for closing the skill-transfer gap. PMID:28584342

    Local governments attempting to respond to environmental change face an array of challenges. To better understand policy responses and factors influencing local government capacity to respond to environmental change, we studied three environmental issues affecting rural or peri-urban towns in different regions of New York State: climate change in the Adirondacks (n = 63 towns), loss of open space due to residential/commercial development in the Hudson Valley (n = 50), and natural gas development in the Southern Tier (n = 62). Our analysis focused on towns' progression through three key stages of the environmental policy process (issue awareness and salience, common goals and agenda setting, policy development and implementation) and the factors that affect this progression and overall capacity for environmental governance. We found that-when compared to towns addressing open space development and natural gas development-towns confronted with climate change were at a much earlier stage in the policy process and were generally less likely to display the essential resources, social support, and political legitimacy needed for an effective policy response. Social capital cultivated through collaboration and networking was strongly associated with towns' policy response across all regions and could help municipalities overcome omnipresent resource constraints. By comparing and contrasting municipal responses to each issue, this study highlights the processes and factors influencing local government capacity to address a range of environmental changes across diverse management contexts.

    Globally, alum sludge is an easily, locally and largely available by-product from water treatment plants where aluminium sulphate is used as the coagulant for raw water purification. Owing to the high content of Al ions (29.7±13.3% dry weight) in alum sludge and the strong affinity of Al ions to adsorb various pollutants especially phosphorus (P), alum sludge (in the form of dewatered cakes) has been investigated in recent years as a low-cost alternative substrate in constructed wetland (CW) systems to enhance the treatment efficiency especially for high strength P-containing wastewater. Long-term trials in different scales have demonstrated that the alum sludge-based CW is a promising technique with a two-pronged feature of using 'waste' for wastewater treatment. Alum sludge cakes in CW can serve as a medium for wetland plant growth, as a carrier for biofilm development and as a porous material for wastewater infiltration. After the intensive studies of the alum sludge-based CW system, this paper aims to address the key issues and concerns pertaining to this kind of CW system. These include: (1) Is alum sludge suitable for reuse in CWs? (2) Is Al released from the sludge a concern? (3) What is the lifespan of the alum sludge in CWs? (4) How can P be recovered from the used alum sludge? (5) Does clogging happen in alum sludge-based CW systems and what is the solution?

    Martinez, Ruben G; Lewis, Cara C; Weiner, Bryan J

    2014-09-04

    Like many new fields, implementation science has become vulnerable to instrumentation issues that potentially threaten the strength of the developing knowledge base. For instance, many implementation studies report findings based on instruments that do not have established psychometric properties. This article aims to review six pressing instrumentation issues, discuss the impact of these issues on the field, and provide practical recommendations. This debate centers on the impact of the following instrumentation issues: use of frameworks, theories, and models; role of psychometric properties; use of 'home-grown' and adapted instruments; choosing the most appropriate evaluation method and approach; practicality; and need for decision-making tools. Practical recommendations include: use of consensus definitions for key implementation constructs; reporting standards (e.g., regarding psychometrics, instrument adaptation); when to use multiple forms of observation and mixed methods; and accessing instrument repositories and decision aid tools. This debate provides an overview of six key instrumentation issues and offers several courses of action to limit the impact of these issues on the field. With careful attention to these issues, the field of implementation science can potentially move forward at the rapid pace that is respectfully demanded by community stakeholders.

  11. Environmental permitting in Thailand

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

    Byers, A.C.

    Thailand's 1992 enhancement and Conservation of Environmental Quality Act and regulations require any entry proposing to construct a thermal power plant with a capacity greater that 10 MW to perform various environmental studies and prepare an environmental Impact Assessment (EIA) report in accordance with the guidelines issued by the office of Environmental Policy and Planning (OEPP). Approval of the EIA is a prerequisite to the issuance of most other construction permits. Applicable environmental standards and regulation are promulgated by the Pollution Control Department (PCD), a wholly separate agency for the OEPP. The PCD is a fairly new organization and, asmore » a result, their staff is still gaining understanding of the multiple environmental aspects of power generation. Accordingly, the PCD is still in process of drafting key regulations applicable to the power industry. This paper examines the current guidelines, practices, procedures and legal requirements regarding environmental licensing of a thermal power plant in Thailand. The requisite scope and content of the EIA report will be identified, as well as the current procedure for its official review and approval by the OEPP. The paper will address the challenges of working with local consultants and identify potential pitfalls in the report preparation process. Areas of particular interest in the EIA review will be identified based on recent examples of OEPP comments on previous SPP and IPP projects. Additionally, the development of applicable environmental standards by the PCD will be identified along with their plans for implementing these standards. The paper will also examine the relationship of the OEPP and PCD, and reflect upon trends for environmental regulation in Thailand in the near future.« less

  13. Sulfur, a Key Water Quality Issue in the Everglades

    NASA Astrophysics Data System (ADS)

    Orem, W. H.; Lerch, H. E.; Bates, A. L.; Corum, M.; Beck, M.; Kleckner, S.

    2002-05-01

    Sulfur is an important water quality issue in the Everglades because of its role in microbial sulfate reduction and the methylation of mercury. Methylmercury (MeHg), a neurotoxin that is bioaccumulated, has been found in high concentrations in freshwater fish from the Everglades, and poses a potential threat to fish-eating wildlife and to human health through fish consumption. Sulfur appears to play a key role in regulating both the magnitude and distribution of MeHg in the Everglades. Freshwater wetlands typically have low sulfur concentrations, but marshes in portions of the northern Everglades have average surface water sulfate concentrations of 60 mg/l, compared to 1 mg/l or less at background sites. Marsh areas with excess sulfate are concentrated near sites of canal discharge and along canal levees. The canal water that is discharged into the marshes appears to be the major source of excess sulfate entering the Everglades. This canal water drains the Everglades Agricultural Area (EAA) and has sulfate concentrations averaging over 70 mg/l and periodically approaching 200 mg/l. We used sulfate concentration data and the sulfur (d34S) isotopic composition of sulfate in marsh surface water, canal water, rainwater, and groundwater to trace the source of the excess sulfate entering the Everglades. Results show that canal water from the EAA is the major source of excess sulfate entering the Everglades. Furthermore, canal water with the highest sulfate concentrations had d34S values of +16 per mil, similar to the d34S signature of agricultural sulfur used as a soil amendment in the EAA. Rainwater has too little sulfate to account for the high sulfate concentrations observed in the canals and in large portions of the Everglades. Groundwater beneath the present day Everglades generally has either too low a sulfate concentration or a d34S signature that is inconsistent with that of surface water in the Everglades. The excess sulfate entering the Everglades from canal

    Issues and design requirements for the environmental barrier coating (EBC)/thermal barrier coating (TBC) life that are general and those specific to the NASA Ultra-Efficient Engine Technology (UEET) development program have been described. The current state and trend of the research, methods in vogue related to the failure analysis, and long-term behavior and life prediction of EBCITBC systems are reported. Also, the perceived failure mechanisms, variables, and related uncertainties governing the EBCITBC system life are summarized. A combined heat transfer and structural analysis approach based on the oxidation kinetics using the Arrhenius theory is proposed to develop a life prediction model for the EBC/TBC systems.

    Field trip method through investigation of local biodiversity cases can give educational experiences for students. This learning activity was efforts to reveal students environmental literacy on biodiversity. The aim of study were (1) to describe the activities of students get information about the biodiversity issue and its context through field trip, (2) to describe the students findings during field trip, and (3) to reveal students environmental literacy based on pre test and post test. The research method used weak-experiment and involved 34 participants at senior high school students in Bandung-Indonesia. The research instruments for collecting data were environmental literacy test, observation sheets and questionnaire sheets for students. The analysis of data was quantitative descriptive. The results show that more than 79% of the students gave positive view for each field trip activity, i.e students activity during work (97%-100%); students activity during gather information (79%- 100%); students activity during exchange information with friend (82%-100%); and students interested to Biodiversity after field trip activity (85%-100%). Students gain knowledge about the diversity of animal vertebrate and its characteristics, the status and condition of animals, and the source of animal with the cases of animal diversity. The students environmental literacy tends to be moderate level based on test. Meanwhile, the average of the attitudes and action greater than the components of knowledge and cognitive skills.

    Increasing marine vessel traffic, and oil and gas exploration and development throughout the North Pacific basin brings increasing risks of oil spills. Recognizing the serious challenges presented to response authorities, this Special Issue was organized by the North Pacific Marine Science Organization to provide an introduction to the current state of scientific understanding regarding the environmental effects of oil spills. Because interactions of spilled oils with biota and their habitats are complex, the most serious environmental damages from these spills are not necessarily those of greatest immediate concern by the public. Our overarching goal for this Special Issue is to provide an efficient introduction to the most important ways that oil spills can harm biota, habitats, and ecosystems through invited, targeted mini-reviews augmented by original research articles. We provide a brief background on the challenges posed by large oil spills to response authorities, summarize findings from the articles published in this Special Issue, and highlight some key research needs.

    Global ecological security becomes increasingly important with the intensive human activities. The function of ecological security is influenced by human activities, and in return, the efficiency of human activities will also be affected by the patterns of regional ecological security. Since the 1990s, China has initiated the construction of key projects "Yangtze Three Gorges Dam", "Qinghai-Tibet Railway", "West-to-East Gas Pipeline", "West-to-East Electricity Transmission" and "South-to-North Water Transfer" , etc. The interaction between these projects and regional ecological security has particularly attracted the attention of Chinese government. It is not only important for the regional environmental protection, but also of significance for the smoothly implementation of various projects aimed to develop an ecological rehabilitation system and to design a regional ecological security pattern. This paper made a systematic analysis on the types and characteristics of key project construction and their effects on the environment, and on the basis of this, brought forward the basic principles and methodology for ecological rehabilitation and security pattern design in this construction. It was considered that the following issues should be addressed in the implementation of a key project: 1) analysis and evaluation of current regional ecological environment, 2) evaluation of anthropogenic disturbances and their ecological risk, 3) regional ecological rehabilitation and security pattern design, 4) scenario analysis of environmental benefits of regional ecological security pattern, 5) re-optimization of regional ecological system framework, and 6) establishment of regional ecosystem management plan.

    Body dysmorphic disorder (BDD), a distressing or impairing preoccupation with an imagined or slight defect in appearance, has been described for more than a century and increasingly studied over the past several decades. This paper provides a focused review of issues pertaining to BDD that are relevant to DSM-V. The review presents a number of options and preliminary recommendations to be considered for DSM-V: 1) Criterion A may benefit from some rewording, without changing its focus or meaning; 2) Potential disadvantages of adding a new criterion to reflect BDD compulsive behaviors seem to outweigh potential advantages, but adding such a criterion remains an option that can be considered; 3) A clinical significance criterion seems necessary for BDD to differentiate it from normal appearance concerns; 4) BDD and eating disorders have some overlapping features and need to be differentiated; some minor changes to DSM-IV’s criterion C are suggested; 5) BDD should not be broadened to include body integrity identity disorder (apotemnophilia) or olfactory reference syndrome; 6) There is no compelling evidence for including diagnostic features or subtypes that are specific to gender-related, age-related, or cultural manifestations of BDD; 7) Adding muscle dysmorphia as a specifier may have clinical utility; and 8) The ICD-10 criteria for hypochondriacal disorder are not suitable for BDD, and there is no empirical evidence that BDD and hypochondriasis are the same disorder. The issue of how BDD’s delusional variant should be classified in DSM-V is briefly discussed and will be addressed more extensively in a separate paper. PMID:20533368

    Differences in environmental priorities within an urban neighborhood of Beirut are analyzed. The explanatory capabilities of five categories of contextual variables are compared: socioeconomic status, locality, health, behavior, and environmental beliefs. Semi-structured interviews with key individuals in the community and residents were first conducted. Four environmental issues of concern were identified. A survey was carried out to identify the relative priority accorded by respondents to these four issues, and to measure variables likely to explain differences of opinion. Bivariate and multivariate logistic regression analyses were conducted for each of the four problems. The 99% confidence interval (CI) of the odds ratio (OR) was used as a test of significance. Respondents suffering from a respiratory disease (OR = 6.94, 99%CI = 1.54-31.25), those living in less crowded houses (OR = 4.88, 99%CI = 1.38-17.24), and those not living close to the neighborhood's industrial street (OR=5.26, 99%CI = 1.01-27.78) are significantly more likely to rank poor air quality first. Significant associations are found between poor water quality as first priority and nonpresence of a smoker in the household (OR = 6.12, 99%CI = 1.84-20.32) and perception of water salinity as a problem (OR = 7.46, 99%CI = 1.50-37.03). Males (OR = 6.94, 99%CI = 1.02-47.62) and tenants versus owners (OR = 10.49, 99%CI = 1.36-80.61) are significantly more likely to rank the residential-industrial mix first. Socioeconomic variables retain their explanatory capability in the studied neighborhood, despite relatively small income disparities. Behavioral variables, such as smoking, may be causative factors of priorities. Analyzing relative priorities, rather than "concern" or lack of it, reveals more complex patterns of association. Identifying environmental-perception divide lines can help develop a more inclusive and effective participatory environmental management.

    The environmental impact of coal mining and burning of coal is evident and generally easy to understand. However, students often struggle to understand the social impacts of coal mining. A jigsaw activity culminating in a mock town hall meeting helps students link social, economic and environmental impacts of coal mining. Students are divided into four groups and assigned the task of researching the environmental, social, economic or health impacts of coal mining in West Virginia. When students have completed the research, they are assigned a role for the town hall. Roles include local community members, direct employees of the coal industry, business owners from industries related to coal mining, and environmentalists. One student from each research area is assigned to each role, forcing students to consider environmental, social, health and economic aspects of coal mining in choosing an appropriate position for their role. Students have 30 minutes to prepare their positions and then present for 2-5 minutes in the simulated town hall. We then have open class discussion and review the positions. Finally, students are required to write a letter to the editor of the local paper. The specific topic for the town hall and letters can be varied based on current events and could include new regulations on power plants, mine safety, government funding of alternative energy supplies or a range of other topics. This approach forces students to consider all aspects of the issue. In addition, because students have to assume a role, they are more aware of the direct impact that coal mining has on individuals' lives.

  8. Technical issues affecting the implementation of US Environmental Protection Agency's proposed fish tissue-based aquatic criterion for selenium.

    2007-10-01

    The US Environmental Protection Agency is developing a national water quality criterion for selenium that is based on concentrations of the element in fish tissue. Although this approach offers advantages over the current water-based regulations, it also presents new challenges with respect to implementation. A comprehensive protocol that answers the "what, where, and when" is essential with the new tissue-based approach in order to ensure proper acquisition of data that apply to the criterion. Dischargers will need to understand selenium transport, cycling, and bioaccumulation in order to effectively monitor for the criterion and, if necessary, develop site-specific standards. This paper discusses 11 key issues that affect the implementation of a tissue-based criterion, ranging from the selection of fish species to the importance of hydrological units in the sampling design. It also outlines a strategy that incorporates both water column and tissue-based approaches. A national generic safety-net water criterion could be combined with a fish tissue-based criterion for site-specific implementation. For the majority of waters nationwide, National Pollution Discharge Elimination System permitting and other activities associated with the Clean Water Act could continue without the increased expense of sampling and interpreting biological materials. Dischargers would do biotic sampling intermittently (not a routine monitoring burden) on fish tissue relative to the fish tissue criterion. Only when the fish tissue criterion is exceeded would a full site-specific analysis including development of intermedia translation factors be necessary.

    This study focuses on assessing the state of population distribution, land cover distribution, biodiversity hotspots, and protected areas in global coastal zones. The coastal zone is defined as land within 100 km of the coastline. This study attempts to answer such questions as: how crowded are the coastal zones, what is the pattern of land cover distribution in these areas, how much of these areas are designated as protected areas, what is the state of the biodiversity hotspots, and what are the interconnections between people and coastal environment. This study uses globally consistent and comprehensive geospatial datasets based on remote sensing and other sources. The application of Geographic Information System (GIS) layering methods and consistent datasets has made it possible to identify and quantify selected coastal zones environmental issues and their interconnections. It is expected that such information provide a scientific basis for global coastal zones management and assist in policy formulations at the national and international levels.

  14. Committing to creating time for integrating contemporary environmental issues into a traditional introduction to Earth Science course, one topic at a time

    2014-12-01

    I teach an Earth Science course, designed as an introductory science class that also fulfills the Earth Science requirement for pre-service teachers preparing to take their state content exam. This course provides an introduction to astronomy, geology, oceanography, and meteorology. By design, the class is content-heavy. Despite this, with so many current environmental and societal issues directly tied to the Earth Sciences, it is essential to address contemporary problems and to educate students about the changes and challenges in the world around them. I have made a commitment to doing this by incorporating relevant societal and environmental issues into every topic and every class session. While this may sound basic, doing so requires diligence and research. For example, when teaching about weathering and erosion, I discuss soils, soil quality and erosion, and the impact this has on our global food supply. A hands-on mineral activity lends itself to looking at the energy and waste involved in ore extraction. A lecture on ocean circulation results in an opportunity to analyze the consequences of the interruption of this pattern due to global warming. Through this approach, students are provided with necessary content; furthermore, by linking traditional content to modern issues on a regular basis, students see the relevance of what they are learning and become more aware of the environmental issues facing society today. Student evaluations indicate that this approach has been successful: 100% of students reported that they learned a great deal from the course, and 100% of students agreed that the quality of the course was high. In addition, prior to the class 55.8% of the students indicated interested in the content; whereas, after the course 88.6% indicated interest, with strong interest in the content increasing from 16.3% to 41%.

    This paper has studied the key issues about integration of GNSS and strong-motion records for real-time earthquake monitoring. The validations show that the consistence of the coordinate system must be considered firstly to exclude the system bias between GNSS and strong-motion. The GNSS sampling rate is suggested about 1-5 Hz, and we should give the strong-motion's baseline shift with a larger dynamic noise as its variation is very swift. The initialization time of solving the baseline shift is less than one minute, and ambiguity resolution strategy is not greatly improved the solution. The data quality is very important for the solution, we advised to use multi-frequency and multi-system observations. These ideas give an important guide for real-time earthquake monitoring and early warning by the tight integration of GNSS and strong-motion records.

  16. Issues in Assessing Environmental Exposures to Manufactured Nanomaterials

    PubMed Central

    Loux, Nicholas T.; Su, Yee San; Hassan, Sayed M.

    2011-01-01

    Manufactured nanomaterials (MNs) are commonly considered to be commercial products possessing at least one dimension in the size range of 10−9 m to 10−7 m. As particles in this size range represent the smaller fraction of colloidal particles characterized by dimensions of 10−9 m to 10−6 m, they differ from both molecular species and bulk particulate matter in the sense that they are unlikely to exhibit significant settling under normal gravitational conditions and they are also likely to exhibit significantly diminished diffusivities (when compared to truly dissolved species) in environmental media. As air/water, air/soil, and water/soil intermedium transport is governed by diffusive processes in the absence of significant gravitational and inertial impaction processes in environmental systems, models of MN environmental intermedium transport behavior will likely require an emphasis on kinetic approaches. This review focuses on the likely environmental fate and transport of MNs in atmospheric and aquatic systems. Should significant atmospheric MNs emission occur, previous observations suggest that MNs may likely exhibit an atmospheric residence time of ten to twenty days. Moreover, while atmospheric MN aggregates in a size range of 10−7 m to 10−6 m will likely be most mobile, they are least likely to deposit in the human respiratory system. An examination of various procedures including the Derjaguin-Landau-Verwey-Overbeek (DLVO) theory of colloidal particle suspension stability in water indicates that more sophisticated approaches may be necessary in order to develop aquatic exposure models of acceptable uncertainty. In addition, concepts such as Critical Coagulation Concentrations and Critical Zeta Potentials may prove to be quite useful in environmental aquatic exposure assessments. PMID:22016703

    Local environmental grassroots activism is robust and globally ubiquitous despite the ebbs and flows of the general environmental movement. In this review we synthesize social movement, environmental politics, and environmental psychology literatures to answer the following questions: How does the environment emerge as a topic for community action and how a particular environmental discourse (preservation, conservation, public health, Deep Ecology, justice, localism and other responses to modernization and development) becomes dominant? How does a community coalesce around the environmental issue and its particular framing? What is the relationship between local and supralocal (regional, national, global) activism? We contrast “Not in My Back Yard” (NIMBY) activism and environmental liberation and discuss the significance of local knowledge and scale, nature as an issue for activism, place attachment and its disruption, and place-based power inequalities. Environmental psychology contributions to established scholarship on environmental activism are proposed: the components of place attachment are conceptualized in novel ways and a continuous dweller and activist place attachment is elaborated.

    This paper analyses the 2016 environmental benchmark performance of the port sector, based on a wide representation of EcoPorts members. This is the fifth time that this study has been conducted as an initiative of the European Sea Ports Organisation (ESPO). The data and results are derived from the Self-Diagnosis Method (SDM), a concise checklist against which port managers can self-assess the environmental management of their port in relation to the performance of the EcoPorts membership. The SDM tool was developed in the framework of the ECOPORTS project (2002-2005) and it is managed by ESPO. A total number of 91 ports from 20 different European Maritime States contributed to this evaluation. The main results are that air quality remains as the top environmental priority of the respondent ports, followed by energy consumption and noise. In terms of environmental management, the study confirms that key components are commonly implemented in the majority of European ports. 94% of contributing ports have a designated environmental manager, 92% own an environmental policy and 82% implement an environmental monitoring program. Waste is identified as the most monitored issue in ports (80%), followed by energy consumption (73%) and water quality (70%). Copyright © 2017 Elsevier Ltd. All rights reserved.

    The lithium ion system considered in this report uses lithium intercalation compounds as both positive and negative electrodes and has an organic liquid electrolyte. Oxides of nickel, cobalt, and manganese are used in the positive electrode, and carbon is used in the negative electrode. This report presents health and safety issues, environmental issues, and shipping requirements for lithium ion electric vehicle (EV) batteries. A lithium-based electrochemical system can, in theory, achieve higher energy density than systems using other elements. The lithium ion system is less reactive and more reliable than present lithium metal systems and has possible performance advantages overmore » some lithium solid polymer electrolyte batteries. However, the possibility of electrolyte spills could be a disadvantage of a liquid electrolyte system compared to a solid electrolyte. The lithium ion system is a developing technology, so there is some uncertainty regarding which materials will be used in an EV-sized battery. This report reviews the materials presented in the open literature within the context of health and safety issues, considering intrinsic material hazards, mitigation of material hazards, and safety testing. Some possible lithium ion battery materials are toxic, carcinogenic, or could undergo chemical reactions that produce hazardous heat or gases. Toxic materials include lithium compounds, nickel compounds, arsenic compounds, and dimethoxyethane. Carcinogenic materials include nickel compounds, arsenic compounds, and (possibly) cobalt compounds, copper, and polypropylene. Lithiated negative electrode materials could be reactive. However, because information about the exact compounds that will be used in future batteries is proprietary, ongoing research will determine which specific hazards will apply.« less

  1. The influence of farmer demographic characteristics on environmental behaviour: a review.

    PubMed

    Burton, Rob J F

    2014-03-15

    Many agricultural studies have observed a relationship between farmer demographic characteristics and environmental behaviours. These relationships are frequently employed in the construction of models, the identification of farmer types, or as part of more descriptive analyses aimed at understanding farmers' environmental behaviour. However, they have also often been found to be inconsistent or contradictory. Although a considerable body of literature has built up around the subject area, research has a tendency to focus on factors such as the direction, strength and consistency of the relationship - leaving the issue of causality largely to speculation. This review addresses this gap by reviewing literature on 4 key demographic variables: age, experience, education, and gender for hypothesised causal links. Overall the review indicates that the issue of causality is a complex one. Inconsistent relationships can be attributed to the presence of multiple causal pathways, the role of scheme factors in determining which pathway is important, inadequately specified measurements of demographic characteristics, and the treatment of non-linear causalities as linear. In addition, all demographic characteristics were perceived to be influenced (to varying extents) by cultural-historical patterns leading to cohort effects or socialised differences in the relationship with environmental behaviour. The paper concludes that more work is required on the issue of causality. Copyright © 2013 Elsevier Ltd. All rights reserved.

    For many decades, access to human biological samples, such as cells, tissues, organs, blood, and sub-cellular materials such as DNA, for use in biomedical research, has been central in understanding the nature and transmission of diseases across the globe. However, the limitations of current ethical and regulatory frameworks in sub-Saharan Africa to govern the collection, export, storage and reuse of these samples have resulted in inconsistencies in practice and a number of ethical concerns for sample donors, researchers and research ethics committees. This paper examines stakeholders' perspectives of and responses to the ethical issues arising from these research practices. We employed a qualitative strategy of inquiry for this research including in-depth interviews and focus group discussions with key research stakeholders in Kenya (Nairobi and Kilifi), and Ghana (Accra and Navrongo). The stakeholders interviewed emphasised the compelling scientific importance of sample export, storage and reuse, and acknowledged the existence of some structures governing these research practices, but they also highlighted the pressing need for a number of practical ethical concerns to be addressed in order to ensure high standards of practice and to maintain public confidence in international research collaborations. These concerns relate to obtaining culturally appropriate consent for sample export and reuse, understanding cultural sensitivities around the use of blood samples, facilitating a degree of local control of samples and sustainable scientific capacity building. Drawing on these findings and existing literature, we argue that the ethical issues arising in practice need to be understood in the context of the interactions between host research institutions and local communities and between collaborating institutions. We propose a set of 'key points-to-consider' for research institutions, ethics committees and funding agencies to address these issues.

    Conyza canadensis has been reported to be the most frequent weed species that evolved resistance to glyphosate in various parts of the world. The objective of the present study was to investigate the effect of environmental conditions (temperature and light) on the expression levels of the EPSPS gene and two major ABC-transporter genes (M10 and M11) on glyphosate susceptible (GS) and glyphosate resistant (GR) horseweed populations, collected from several regions across Greece. Real-time PCR was conducted to determine the expression level of the aforementioned genes when glyphosate was applied at normal (1×; 533 g·a.e.·ha(-1)) and high rates (4×, 8×), measured at an early one day after treatment (DAT) and a later stage (four DAT) of expression. Plants were exposed to light or dark conditions, at three temperature regimes (8, 25, 35 °C). GR plants were made sensitive when exposed to 8 °C with light; those sensitized plants behaved biochemically (shikimate accumulation) and molecularly (expression of EPSPS and ABC-genes) like the GS plants. Results from the current study show the direct link between the environmental conditions and the induction level of the above key genes that likely affect the efficiency of the proposed mechanism of glyphosate resistance.

    The environmental sciences are at the forefront of critical issues facing society in the coming decades. As a result, many graduates in the environmental sciences find themselves working with the public to help inform the democratic process of making reasonable public policies. In order to be successful, students need to be confronted with the same kinds of questions and problems that practicing scientists face when they are working at the intersection of science and public policy. Otherwise, they lack the skills and confidence needed to work effectively with the public—especially on hotly contested environmental issues when the skills are needed the most. As part of a new Professional Science Master's (PSM) Program in Climate Science and Solutions at Northern Arizona University we have developed a three-semester course series focused on framing discussions on climate change mitigation and adaptation. Each semester, students use a deliberative model to design, frame, and facilitate a public discussion on a targeted issue of regional and local interest. The deliberative model is built around an approach to practical dilemmas that enables students to isolate and clarify the various sources of conflict around the issue. Working in an iterative manner, students learn to identify and untangling some of the sources of disagreement (e.g., policy, ethics and ideals, difference in scientific understanding) around and issue. As a result, students are in a much better position to clarify the key questions and sort through the competing solutions. The course series helps to improve the communication skills of students and promote productive public discourse with individuals from diverse backgrounds within the community. This type of experiential learning provides unique training to our students that not only broadens there understanding of complex issues surrounding climate change, but also provides them with professional skills that are transferrable to their careers.

  9. PM₂.₅ opened a door to public participation addressing environmental challenges in China.

    2015-02-01

    China has long been regarded as a centralized society where the public has little influence on decision-making. Such a top-down management scheme is perceived as a major obstacle to address complicated environment issues. The recent public campaign in China to urge creation of a nationwide PM₂.₅ monitoring network and mitigation plan provides an unprecedented case of how the public participated and influenced policy-making in a centralized society. This paper reviews key incidents in the campaign chronologically. Here we identify information technology, public awareness of air quality's health impacts and the fact air quality affects everyone as public goods as the major factors promoting public participation. This case demonstrates that public participation can happen in a centralized, top-down society such as China. Continued environmental deterioration may stimulate similar campaigns for other issues. We anticipate this essay to be a starting point for more studies on how environmental issues stimulate incremental social change by making people involved in decision-making process, especially in societies where they are rarely able to do so.

    2013-10-01

    Environmental issues related to swine production are still a major concern for the general public and represent a key challenge for the swine industry. The environmental impact of higher livestock concentration is particularly significant where it coincides with weaker policy standards and poor manure management. Effective tools for environmental monitoring of the swine sewage management process become essential for verifying the environmental compatibility of farming facilities and for defining suitable policies aimed at increasing swine production sustainability. This research aims at the development and application of a model for a quick assessment of the environmental effectiveness of the pig farming sewage management process. In order to define the model, multicriteria techniques, and in particular, Saaty's analytic hierarchy process, were used to develop an iterative process in which the various key factors influencing the process under investigation were analyzed. The model, named EASE (Environmental Assessment of Sewages management Effectiveness), was optimized and applied to the Lake Trasimeno basin (Umbria, Italy), an area of high natural, environmental and aesthetic value. In this context, inadequate disposal of pig sewage represents a potential source of very considerable pollution. The results have demonstrated how the multicriteria model can represent a very effective and adaptable tool also in those decision-making processes aimed at the sustainable management of livestock production.

We move beyond the question of reputation to address key conflicts in the history of occupational medicine, including the American Occupational Medical Association's historical role in weakening the beryllium standard and the American College of Occupational and Environmental Medicine's recent efforts to limit the extent of the Family Medical Leave Act. The corporate practice of externalizing health and safety costs makes industry influence an important ongoing topic of debate in occupational and environmental medicine.

    Responsible international project developers most often view environmental matters with quite mixed emotions. Those with whom Dynalytics has worked would certainly never contemplate jeopardizing the health of anyone in the world. But while they want their projects realized, and are willing to implement reasonable requirements, they are often asked to do more than is appropriate, more than is technologically possible, and more than is financially possible. The paper discusses the following: who is in charge of environmental matters; whose environmental standards apply; the role of technology; accelerating timetables and reducing costs; documentation and applications; and post-construction requirements.

    One key factor that limits the performance of current gas turbine engines is the temperature capability of hot section structural components. Silicon-based ceramics, such as SiC/SiC composites and monolithic Si3N4, are leading candidates to replace superalloy hot section components in the next generation gas turbine engines due to their excellent high temperature properties. A major stumbling block to realizing Si-based ceramic hot section components is the recession of Si-based ceramics in combustion environments due to the volatilization of silica scale by water vapor. An external environmental barrier coating (EBC) is the most promising approach to preventing the recession. Current EBCs are based on silicon, mullite (3A12O3-2SiO2) and BSAS (barium strontium aluminum silicate with celsian structure). Volatility of BSAS, BSAS-silica chemical reaction, and low melting point of silicon limit the durability and temperature capability of current EBCs. Research is underway to develop EBCs with longer life and enhanced temperature capability. Understanding key issues affecting the performance of current EBCs is necessary for successful development of advanced EBCs. These issues include stress, chemical compatibility, adherence, and water vapor stability. Factors that affect stress are thermal expansion mismatch, phase stability, chemical stability, elastic modulus, etc. The current understanding on these issues will be discussed.

The challenge is enormous but there is growing evidence that sound environmental management provides pay-off in bottom line results. Business organizations have a vital role to play and its good for them. There are opportunities for new business as well as threats to those organizations which continue to ignore the trends.

    The environmental barrier coating (EBC) for SiC/SiC ceramic matrix composites and Si3N4 ceramics is an emerging field as the application of silicon-based ceramics in the gas turbine engine hot section is on the horizon, both for aero and industrial gas turbines. EBC is an enabling technology for silicon-based ceramics because these materials without an EBC cannot be used in combustion environments due to rapid surface recession. Significant progress in EBC development has been made during the last decade through various government-sponsored programs. Current EBCs are based on silicon, mullite (3Al2O3-2SiO2) and BSAS (barium strontium aluminum silicate with celsian structure). Volatility of BSAS, BSAS-silica chemical reaction, and low melting point of silicon limit temperature capability of current EBCs to about 1350 C for long-term applications. There is a need for higher temperature EBCs as the temperature capability of silicon-based ceramics continue to increase. Therefore, research is underway to develop EBCs with improved temperature capability compared to current EBCs. The current status and issues with the advanced EBC development efforts will be discussed.

    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

  6. Developmental models for estimating ecological responses to environmental variability: structural, parametric, and experimental issues.

    PubMed

    Moore, Julia L; Remais, Justin V

    2014-03-01

    Developmental models that account for the metabolic effect of temperature variability on poikilotherms, such as degree-day models, have been widely used to study organism emergence, range and development, particularly in agricultural and vector-borne disease contexts. Though simple and easy to use, structural and parametric issues can influence the outputs of such models, often substantially. Because the underlying assumptions and limitations of these models have rarely been considered, this paper reviews the structural, parametric, and experimental issues that arise when using degree-day models, including the implications of particular structural or parametric choices, as well as assumptions that underlie commonly used models. Linear and non-linear developmental functions are compared, as are common methods used to incorporate temperature thresholds and calculate daily degree-days. Substantial differences in predicted emergence time arose when using linear versus non-linear developmental functions to model the emergence time in a model organism. The optimal method for calculating degree-days depends upon where key temperature threshold parameters fall relative to the daily minimum and maximum temperatures, as well as the shape of the daily temperature curve. No method is shown to be universally superior, though one commonly used method, the daily average method, consistently provides accurate results. The sensitivity of model projections to these methodological issues highlights the need to make structural and parametric selections based on a careful consideration of the specific biological response of the organism under study, and the specific temperature conditions of the geographic regions of interest. When degree-day model limitations are considered and model assumptions met, the models can be a powerful tool for studying temperature-dependent development.

    The Arctic is an interconnected and environmentally sensitive system of ice, ocean, land, atmosphere, ecosystems, and people. From local to pan-Arctic scales, the area has already undergone major changes in physical and societal systems and will continue at a pace that is greater than twice the global average. Key Arctic indicators can quantify these changes. Indicators serve as the bridge between complex information and policy makers, stakeholders, and the general public, revealing trends and information people need to make important socioeconomic decisions. This presentation evaluates and compiles more than 70 physical, biological, societal and economic indicators into an approachable summary that defines the changing Arctic. We divided indicators into "existing," "in development," "possible," and "aspirational". In preparing a paper on Arctic Indicators for a special issue of the journal Climatic Change, our group established a set of selection criteria to identify indicators to specifically guide decision-makers in their responses to climate change. A goal of the analysis is to select a manageable composite list of recommended indicators based on sustained, reliable data sources with known user communities. The selected list is also based on the development of a conceptual model that identifies components and processes critical to our understanding of the Arctic region. This list of key indicators is designed to inform the plans and priorities of multiple groups such as the U.S. Global Change Research Program (USGCRP), Interagency Arctic Research Policy Committee (IARPC), and the Arctic Council.

    A variety of modeling approaches can be used to project the future development of forest systems, and help to assess the implications of different management alternatives for biodiversity and ecosystem services. This diversity of approaches does however present both an opportunity and an obstacle for those trying to decide which modeling technique to apply, and interpreting the management implications of model output. Furthermore, the breadth of issues relevant to addressing key questions related to forest ecology, conservation biology, silviculture, economics, requires insights stemming from a number of distinct scientific disciplines. As forest planners, conservation ecologists, ecological economists and silviculturalists, experienced with modeling trade-offs and synergies between biodiversity and wood biomass production, we identified fifteen key considerations relevant to assessing the pros and cons of alternative modeling approaches. Specifically we identified key considerations linked to study question formulation, modeling forest dynamics, forest processes, study landscapes, spatial and temporal aspects, and the key response metrics - biodiversity and wood biomass production, as well as dealing with trade-offs and uncertainties. We also provide illustrative examples from the modeling literature stemming from the key considerations assessed. We use our findings to reiterate the need for explicitly addressing and conveying the limitations and uncertainties of any modeling approach taken, and the need for interdisciplinary research efforts when addressing the conservation of biodiversity and sustainable use of environmental resources.

    Although obstetrician-gynecologists recognize the importance of managing fertility for the reproductive health of individuals, many are not aware of the vital effect they can have on some of the world's most pressing issues. Unintended pregnancy is a key contributor to the rapid population growth that in turn impairs social welfare, hinders economic progress, and exacerbates environmental degradation. An estimated 215 million women in developing countries wish to limit their fertility but do not have access to effective contraception. In the United States, half of all pregnancies are unplanned. Voluntary prevention of unplanned pregnancies is a cost-effective, humane way to limit population growth, slow environmental degradation, and yield other health and welfare benefits. Family planning should be a top priority for our specialty.

    An experimental and computational study, consisting of modeling and simulation (M&S), of key thermal-mechanical issues affecting the design and safety of pebble-bed (PB) reactors was conducted. The objective was to broaden understanding and experimentally validate thermal-mechanic phenomena of nuclear grade graphite, specifically, spheres in frictional contact as anticipated in the bed under reactor relevant pressures and temperatures. The contact generates graphite dust particulates that can subsequently be transported into the flowing gaseous coolent. Under postulated depressurization transients and with the potential for leaked fission products to be adsorbed onto graphite 'dust', there is the potential for fission products to escapemore » from the primary volume. This is a design safety concern. Furthermore, earlier safety assessment identified the distinct possibility for the dispersed dust to combust in contact with air if sufficient conditions are met. Both of these phenomena were noted as important to design review and containing uncertainty to warrant study. The team designed and conducted two separate effects tests to study and benchmark the potential dust-generation rate, as well as study the conditions under which a dust explosion may occure in a standardized, instrumented explosion chamber.« less

    The Hewlett Program in Environmental Sustainability, an experimental educational pathway for undergraduate students interested in the study of the environment (http://wundow.wustl.edu/hewlett), is now in its third year at Washington University. About 90% of incoming students have stayed with the program through the first year and about 80% through the second year.The program's objectives and implementation closely follow the recommendations presented in a 1998 Boyer Commission Report on emphasizing and improving undergraduate education at research universities (http://notes.cc.sunysb.edu/Pres/boyer/nsf). A clustered, interdisciplinary approach is used for coursework, with key environmental problems viewed from scientific, political, cultural, and ethical perspectives. Courses are taught by instructors who conduct research in environmental areas. The program's multidisciplinary nature is considered a strong draw for faculty involvement, though retaining faculty is still an issue.

    The Idaho National Engineering Laboratory (INEL), in southeastern Idaho, is a principal center for nuclear energy development for the Department of Energy (DOE) and the U.S. Nuclear Navy. Fifty-two reactors have been built at the INEL, with 15 still operable. Extensive environmental surveillance is conducted at the INEL by DOE's Radiological Environmental Sciences Laboratory (RESL), and the U.S. Geological Survey (USGS), the National Oceanic and Atmospheric Administration (NOAA), EG&G Idaho, Inc., and Westinghouse Idaho Nuclear Company (WINCO). Surveillance of waste management facilities radiation is integrated with the overall INEL Site surveillance program. Air, warer, soil, biota, and environmental radiation are monitored or sampled routinely at INEL. Results to date indicate very small or no impacts from INEL on the surrounding environment. Environmental surveillance activities are currently underway to address key environmental issues at the INEL.

    This study was conducted to determine whether the risk of developing multiple sclerosis (MS) was associated with certain environmental exposures or genetic factors previously reported to influence MS risk. This paper describes the methodological issues, study design and characteristics of the study population. Individuals with definite MS were identified from a prevalence study conducted in three geographic areas. The target number of cases was not reached, so an additional study area was added. Identifying clinic controls was inefficient, so controls were recruited using random digit dialing. All study participants completed a detailed questionnaire regarding environmental exposures using computer-assisted telephone interviewing, and blood was collected for genetic analysis. In total, 276 cases and 590 controls participated, but participation rates were low, ranging from 28.4% to 38.9%. Only one-third (33.6%) of individuals identified in the prevalence study agreed to participate in the case-control study. Cases were more likely to be non-Hispanic white and older than their source populations as identified in the preceding prevalence study (P < 0.05). Most participants provided a blood sample for genotyping (91%; n = 789). Epidemiological studies play a key role in identifying genetic and environmental factors that are associated with complex diseases like MS. Methodological issues arise in every study, and investigators need to be able to detect, respond to and correct problems in a timely and scientifically valid manner. © 2011 John Wiley & Sons A/S.

    Throughout most of human history, environmental stewardship during mining has not been a priority partly because of the lack of applicable laws and regulations and partly because of ignorance about the effects that mining can have on the environment. In the United States, the National Environmental Policy Act of 1969, in conjunction with related laws, codified a more modern approach to mining, including the responsibility for environmental stewardship, and provided a framework for incorporating environmental protection into mine planning. Today, similar frameworks are in place in the other developed countries of the world, and international mining companies generally follow similar procedures wherever they work in the world. The regulatory guidance has fostered an international effort among all stakeholders to identify best practices for environmental stewardship.The modern approach to mining using best practices involves the following: (a) establishment of a pre-mining baseline from which to monitor environmental effects during mining and help establish geologically reasonable closure goals; (b) identification of environmental risks related to mining through standardized approaches; and (c) formulation of an environmental closure plan before the start of mining. A key aspect of identifying the environmental risks and mitigating those risks is understanding how the risks vary from one deposit type to another—a concept that forms the basis for geoenvironmental mineral-deposit models.Accompanying the quest for best practices is the goal of making mining sustainable into the future. Sustainable mine development is generally considered to be development that meets the needs of the present generation without compromising the ability of future generations to meet their own needs. The concept extends beyond the availability of nonrenewable mineral commodities and includes the environmental and social effects of mine development.Global population growth, meanwhile, has

    Evidence supports the link between the built environment and physical activity. This study investigated factors that influence the decisions made by key stakeholders as they relate to neighbourhood development. Seventeen stakeholders including public health and municipal employees (n = 9), city councillors (n = 3), and the private sector (e.g., land developers, food retailers) (n = 5), participated in interviews. Private sector participants considered healthy lifestyle choices (e.g., PA) to be related more to individual choice than did other groups. All groups agreed that consumer behaviour is essential to invoking change but did not agree on who is responsible for invoking change. Common barriers included financial costs, car dependency, and social norms. Facilitators included growing awareness of health and environmental issues and increasing buy-in from governing bodies for innovative neighbourhood development. More work is needed that acknowledges the differences between while integrating the diverse perspectives of those responsible for the planning of neighbourhoods that are conducive for physical activity.

  7. Environmental flows for rivers and economic compensation for irrigators.

    Sisto, Nicholas P

    2009-02-01

    Securing flows for environmental purposes from an already fully utilized river is an impossible task--unless users are either coerced into freeing up water, or offered incentives to do so. One sensible strategy for motivating users to liberate volumes is to offer them economic compensation. The right amount for that compensation then becomes a key environmental management issue. This paper analyses a proposal to restore and maintain ecosystems on a stretch of the Río Conchos in northern Mexico, downstream from a large irrigation district that consumes nearly all local flows. We present here estimates of environmental flow requirements for these ecosystems and compute compensation figures for irrigators. These figures are derived from crop-specific irrigation water productivities we statistically estimate from a large set of historical production and irrigation data obtained from the district. This work has general implications for river ecosystem management in water-stressed basins, particularly in terms of the design of fair and effective water sharing mechanisms.

    During the last decade a number of environmental agreements (EAs) have been negotiated in Canada involving industry, government and Aboriginal peoples. This article draws on the Canadian experience to consider the potential of such negotiated agreements to address two issues widely recognised in academic and policy debates on environmental impact assessment (EIA) and environmental management. The first relates to the need to secure indigenous participation in environmental management of major projects that affect indigenous peoples. The second and broader issue involves the necessity for specific initiatives to ensure effective follow-up of EIA. The Canadian experience indicates that negotiated environmental agreementsmore » have considerable potential to address both issues. However, if this potential is to be realized, greater effort must be made to develop structures and processes specifically designed to encourage Aboriginal participation; and EAs must themselves provide the financial and other resource required to support EIA follow-up and Aboriginal participation.« less

    A bibliometric analysis based on the Science Citation Index Expanded from Web of Science was carried out to provide insights into research activities and trends of the environmental monitoring from 1993 to 2012. Study emphases covered publication outputs, language, categories, journals, countries/territories, institutions, words, and hot issues. The results indicated that the annual output of environmental monitoring publications increased steadily. The environmental sciences and analytical chemistry were the two most common categories. Environmental Monitoring and Assessment published the most articles. The USA and the UK ranked in the top two in terms of all five indicators. The U.S. Environmental Protection Agency took the leading position of the institutions in terms of publication output. The synthesized analysis by words in title, author keywords, and KeyWords Plus provided important clues for hot issues. Researchers paid more attention on water environment monitoring than other environmental factors. The contaminants including organic contaminants, heavy metal, and radiation were most common research focuses, and the organic contaminants and heavy metal of the degree of concern were gradually rising. Sensor and biosensor played an important role in the field of environmental monitoring devices. In addition to conventional device detection method, the remote sensing, GIS, and wireless sensor networks were the mainstream environmental monitoring methods. The international organization, social awareness, and the countries' positive and effective political and policies promoted the published articles.

    The environment is increasingly being recognized for the role it might play in the global spread of clinically relevant antibiotic resistance. Environmental regulators monitor and control many of the pathways responsible for the release of resistance-driving chemicals into the environment (e.g., antimicrobials, metals, and biocides). Hence, environmental regulators should be contributing significantly to the development of global and national antimicrobial resistance (AMR) action plans. It is argued that the lack of environment-facing mitigation actions included in existing AMR action plans is likely a function of our poor fundamental understanding of many of the key issues. Here, we aim to present the problem with AMR in the environment through the lens of an environmental regulator, using the Environment Agency (England's regulator) as an example from which parallels can be drawn globally. The issues that are pertinent to environmental regulators are drawn out to answer: What are the drivers and pathways of AMR? How do these relate to the normal work, powers and duties of environmental regulators? What are the knowledge gaps that hinder the delivery of environmental protection from AMR? We offer several thought experiments for how different mitigation strategies might proceed. We conclude that: (1) AMR Action Plans do not tackle all the potentially relevant pathways and drivers of AMR in the environment; and (2) AMR Action Plans are deficient partly because the science to inform policy is lacking and this needs to be addressed.
