Sudharsanam, Manni Balasubramaniam

2014-01-01

Topics on environmental health are usually neglected by students and it is necessary for them to learn this area with a public health perspective as environment plays a vital role in multi-factorial causation of diseases. Hence there is a need for alternative teaching/learning methods to facilitate students in acquiring the required knowledge. To increase the student interest and enhance their participation in acquiring knowledge in public health perspective of environmental health. Teaching Objectives/Learning Were: At the end of the session students should know the importance of air as an environmental factor in disease causation in special reference to public health hazards, the major sources of air pollution, major pollutants causing the health hazards, the way to measure pollutants and control them. The whole class of students was divided into two batches and one session was planned for each batch. Each batch was divided into six small groups. The groups were given task of exploring the internet on the different topics mentioned in the learning objectives. All the students were asked to explore, compile information and collectively prepare a presentation and present their findings based on their reviews. Students' feedback was collected at the end of each session. Eighty five percent of them were clear about the learning objectives and interested about internet learning. Most of them gave a positive opinion about the newer teaching learning method. Internet assisted group study served as a valuable alternative, innovative, and interesting tool to teach and learn the environmental health as revealed by students' feedback.

All hazardous waste politics is local: Grass-roots advocacy and public participation in siting and cleanup decisions

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

Lowry, R.C.

1998-12-31

The combined effects of federalism and interest group pluralism pose particularly difficult problems for hazardous waste siting and cleanup decisions. Most national environmental groups have only limited involvement in local hazardous waste politics, while local grass-roots advocates have very different interests and sometimes are pitted against one another. Both the Environmental protection Agency and the Department of energy recently have begun to use site-specific citizen advisory boards at cleanup sites. This approach appears to improve communications at some sites, but does not address the issues of ``not in my back yard`` politics and alleged inequitable exposure to hazardous wastes.

Supporting multi-stakeholder environmental decisions.

PubMed

Hajkowicz, Stefan A

2008-09-01

This paper examines how multiple criteria analysis (MCA) can be used to support multi-stakeholder environmental management decisions. It presents a study through which 48 stakeholders from environmental, primary production and community interest groups used MCA to prioritise 30 environmental management problems in the Mackay-Whitsunday region of Queensland, Australia. The MCA model, with procedures for aggregating multi-stakeholder output, was used to inform a final decision on the priority of the region's environmental management problems. The result was used in the region's environmental management plan as required under Australia's Natural Heritage Trust programme. The study shows how relatively simple MCA methods can help stakeholders make group decisions, even when they hold strongly conflicting preferences.

Measuring Changes in Interest in Science and Technology at the College Level in Response to Two Instructional Interventions

NASA Astrophysics Data System (ADS)

Romine, William L.; Sadler, Troy D.

2016-06-01

Improving interest in science, technology, engineering, and mathematics (STEM) is crucial to widening participation and success in STEM studies at the college level. To understand how classroom and extracurricular interventions affect interest, it is necessary to have appropriate measurement tools. We describe the adaptation and revalidation of a previously existing multidimensional instrument to the end of measuring interest in environmental science and technology in college nonscience majors. We demonstrate the revised instrument's ability to detect change in this group over an 8-week time period. While collection of demographic information was not part of the study design, participating students were similar in that they hailed from three environmental science nonmajor classes sharing a common syllabus and instructional delivery method. Change in interest was measured in response to two types of scientific literature-based learning approaches: a scientific practice approach and a traditional, quiz-driven approach. We found that both approaches led to moderate gains in interest in learning environmental science and careers in environmental science across an 8-week time period. Interest in using technology for learning increased among students using the scientific practice approach; in contrast, the same measure decreased among students using the reading/quiz approach. This result invites the possibility that interest in using technology as a learning tool may relate to technological literacy, which must be taught explicitly in the context of authentic inquiry experiences.

Developing the community environmental health role of the nurse.

PubMed

Carnegie, Elaine; Kiger, Alice

2010-06-01

This paper is a report from one phase of an exploratory case study. It investigated the environmental health concerns of members of communities within one city in the North East of Scotland. Individual interviews with stakeholders (n=21) and four focus groups were conducted with a convenience sample of community nurses (n=19). Community nurse participants believed that their environmental health role remains underdeveloped. They indicated that they do not view the NHS as a resource for environmental health information. An environmental role is constrained by the NHS not being perceived as a source of information or expert in environmental health. They described limited contact between community nurses and public health medicine and uncertainty and conflict of interest between clinical groups regarding the scope of an environmental health role. Policy makers could support the development of an environmental advocacy role--a pilot of this is required.

Environmental monitoring using autonomous vehicles: a survey of recent searching techniques.

Bayat, Behzad; Crasta, Naveena; Crespi, Alessandro; Pascoal, António M; Ijspeert, Auke

2017-06-01

Autonomous vehicles are becoming an essential tool in a wide range of environmental applications that include ambient data acquisition, remote sensing, and mapping of the spatial extent of pollutant spills. Among these applications, pollution source localization has drawn increasing interest due to its scientific and commercial interest and the emergence of a new breed of robotic vehicles capable of operating in harsh environments without human supervision. The aim is to find the location of a region that is the source of a given substance of interest (e.g. a chemical pollutant at sea or a gas leakage in air) using a group of cooperative autonomous vehicles. Motivated by fast paced advances in this challenging area, this paper surveys recent advances in searching techniques that are at the core of environmental monitoring strategies using autonomous vehicles.

Unconventional politics of unconventional gas: Environmental reframing and policy change

NASA Astrophysics Data System (ADS)

Kear, Andrew Robert

The present Rocky Mountain West natural gas boom, enabled by historic pro-resource-development political, institutional, economic, and cultural structures, is a politically contested battle over values. Volatile political action, unconventional coalitions, and unconventional politics engulf this unconventional gas boom -- especially at the state level. In this comparative case study of natural gas policy in Wyoming, Colorado, and New Mexico, I measure and compare these values, expressed as frames, through textual analysis of interest group public documents and state legislative bills and statutes from 1999-2008. By developing a new measure of state legislative framing, I test the relationship between interest group and institutional framing and also provide a viable measure of policy change useful to Narrative Policy Analysis theory. Results show that competing interest group and state legislative framing efforts are dynamic, measurably different, and periodically correlative. Competing interest groups rarely engage each other, except as the conflict matures when status-quo-supporters break their silence and engage the challengers' frames that have gained legislative traction. Environmental and land-use counter-framing ensues, but status-quo-supporters remain vigilant in their economic framing. Economic frames retain their institutional privilege within Wyoming and New Mexico, but natural gas policy undergoes a complete environmental reframe in the Colorado state legislature. Although the historically dominant economy frame based on "Old West" values remains largely intact, the respective state legislatures partially reframe policy (within 4 years) using environment, alternative land-uses, and democracy frames based on "New West" and long-extant but previously marginalized status-quo-challenger definitions. This reframing is not a strictly partisan issue, but rather it is influenced by political context, policy diffusion, and long-term interest group advocacy and framing efforts. A policy punctuation is observed in state legislative reframing and by the passage of three status-quo-challenging statutes in Wyoming (2005), four in Colorado (2007), and one in New Mexico (2007). Policy reframing, although rare in most policy areas, is common during this natural gas policy punctuation. The politics of successful reframing is the politics of punctuation.

Stop, Collaborate, and Listen: Lessons Learned from Collaborating with a Houston Environmental Justice Organization

NASA Astrophysics Data System (ADS)

Johnson, C.; Arellano, Y.; Phartiyal, P.

2016-12-01

Scientists are increasingly showing interest in conducting research at the community level, yet community groups often struggle with lack of access to scientific information. Collaborations between the two are mutually beneficial: scientists can include assessment of societal implications in their research, and community-specific scientific evidence can be used by local groups to inform public decisions that benefit community interests. Recognizing the need for and utility of such partnerships, the Center for Science and Democracy at the Union of Concerned Scientists, a science-based policy and advocacy organization, partnered with Texas Environmental Justice Advocacy Services (TEJAS), an environmental justice organization based in Manchester in Houston, to provide the technical support and resources needed to strengthen TEJAS' advocacy work. Working closely with TEJAS, we connected community members with local experts, developed educational products to inform community members about environmental health risks in their neighborhoods, published a report highlighting chemical safety issues in the community, and assisted in constructing a community survey to assess residents' health concerns. The products were created with the intention of raising the profile of these issues with local government and regional EPA officials. This talk will discuss the projects done in collaboration with TEJAS, as well as important lessons learned that offer insight into best practices for other organizations and technical experts to partner with community groups on local projects.

Using Inequality Measures to Incorporate Environmental Justice into Regulatory Analyses

PubMed Central

Harper, Sam; Ruder, Eric; Roman, Henry A.; Geggel, Amelia; Nweke, Onyemaechi; Payne-Sturges, Devon; Levy, Jonathan I.

2013-01-01

Formally evaluating how specific policy measures influence environmental justice is challenging, especially in the context of regulatory analyses in which quantitative comparisons are the norm. However, there is a large literature on developing and applying quantitative measures of health inequality in other settings, and these measures may be applicable to environmental regulatory analyses. In this paper, we provide information to assist policy decision makers in determining the viability of using measures of health inequality in the context of environmental regulatory analyses. We conclude that quantification of the distribution of inequalities in health outcomes across social groups of concern, considering both within-group and between-group comparisons, would be consistent with both the structure of regulatory analysis and the core definition of environmental justice. Appropriate application of inequality indicators requires thorough characterization of the baseline distribution of exposures and risks, leveraging data generally available within regulatory analyses. Multiple inequality indicators may be applicable to regulatory analyses, and the choice among indicators should be based on explicit value judgments regarding the dimensions of environmental justice of greatest interest.

Genotype-environment interaction and sociology: contributions and complexities.

PubMed

Seabrook, Jamie A; Avison, William R

2010-05-01

Genotype-environment interaction (G x E) refers to situations in which genetic effects connected to a phenotype are dependent upon variability in the environment, or when genes modify an organism's sensitivity to particular environmental features. Using a typology suggested in the G x E literature, we provide an overview of recent papers that show how social context can trigger a genetic vulnerability, compensate for a genetic vulnerability, control behaviors for which a genetic vulnerability exists, and improve adaptation via proximal causes. We argue that to improve their understanding of social structure, sociologists can take advantage of research in behavior genetics by assessing the impact of within-group variance of various health outcomes and complex human behaviors that are explainable by genotype, environment and their interaction. Insights from life course sociology can aid in ensuring that the dynamic nature of the environment in G x E has been accounted for. Identification of an appropriate entry point for sociologists interested in G x E research could begin with the choice of an environmental feature of interest, a genetic factor of interest, and/or behavior of interest. Optimizing measurement in order to capture the complexity of G x E is critical. Examining the interaction between poorly measured environmental factors and well measured genetic variables will overestimate the effects of genetic variables while underestimating the effect of environmental influences, thereby distorting the interaction between genotype and environment. Although the expense of collecting environmental data is very high, reliable and precise measurement of an environmental pathogen enhances a study's statistical power. Copyright 2010 Elsevier Ltd.

Genomic Insights into the Biomineralization and Environmental Function of Magnetotactic Bacteria

NASA Astrophysics Data System (ADS)

Lin, W.; Pan, Y.

2015-12-01

Microorganisms have populated the Earth for billions of years and their activities are important biologic forces shaping our planetary environments. Microbial biomineralization that selectively take up environmental elements (e.g., C, S, P, Fe) and synthesize minerals either intracellularly or extracellularly is of great interest. One of the most interesting examples of these types of organisms are magnetotactic bacteria (MTB), a polyphyletic group of prokaryotes that uptake iron from aquatic habitats and biomineralize intracellular nano-sized iron minerals of magnetite (Fe3O4) and/or greigite (Fe3S4), known as magnetosomes, and orientate and swim along the Earth's magnetic field. However, our knowledge on the biomineralization mechanisms of MTB and their environmental function remains very limited because the genomic information of most MTB is still not fully understood. By using metagenomic approaches, we have acquired genomic sequences of environmental MTB communities and discovered several conserved genomic fragments containing gene operons for magnetite or greigite biomineralization from Proteobacteria and Nitrospirae MTB. The comparison of these gene clusters has provided valuable insights into the origin and evolution of magnetosome biomineralization. We further obtained several draft genomes of uncultivated MTB belonging to the phylum Nitrospirae, which reveals a metabolic flexibility of this poorly understood magnetotactic group and indicates their considerable roles in the biogeochemical cycles of iron and sulfur.

Interest in biology. Part I: A multidimensional construct

NASA Astrophysics Data System (ADS)

Gardner, Paul L.; Tamir, Pinchas

Interest in a school subject (e.g., biology) is conceptualized in terms of three components: topics, activities, and motives, each of which has several dimensions. In this study, seven instruments were developed and administered to grade-10 biology students in Israel. Factor analysis provided support for the conceptualization which underlies the development of the instruments. Topic dimensions included biochemical processes, nonhuman organisms, human biology, personal hygiene, and practical applications; the activity dimensions were experiential learning, reception learning, writing/summarizing and group discussion; motives included environmental issues, moral issues, examination success, personal independence, problem solving, and four career dimensions (research, high-status professions, lower-status careers, woodsy-birdsy careers). In an analysis described in Part II of this paper, the students were classified into four groups on the basis of their grade-11 subject enrollment intentions: H (high-level biology), L (low-level biology), P (physical science), and N (no science). Zero-order and multiple correlations were found between interest and other variables and membership/nonmembership of the four groups. Students in Group H were characterized by higher achievement in year-10 biology, higher levels of enjoyment of biology, career orientations towards research or high-status biology-based professions, greater interest in various biology topics, especially reproduction/cell division/genetics, and a greater tendency to regard the Bagrut (grade-12) examination as interesting. Students in Group N displayed lower levels of interest in various topics (especially the microscope, plants, and reproduction), were less motivated to solve problems, had poorer grades in biology (and chemistry), were less likely to perceive biology as useful, were less likely to regard the Bagrut examination as fair, and were less likely to be interested in social modes of learning. There were few associations between interest variables and membership in Groups L or P.

Radiation sensors for medical, industrial and environmental applications: how to engage with schools and the general public

NASA Astrophysics Data System (ADS)

Seitz, B.; Campos Rivera, N.; Gray, R.; Powell, A.; Thomson, F.

2018-01-01

Radiation, radiation detection and radiation protection are topics in physics and its applications which generate a wide interest in the public. This interest is either generated through medical procedures, applications of nuclear energy or nuclear accidents. The technical nature of these topics usually means that they are not well covered in the normal education stream, opening many opportunities to engage with schools and the general public to showcase the latest developments and their applications. The detection of radiation is at the very heart of understanding radiation, its fascination and associated fears. The outreach group of the nuclear physics group at the University of Glasgow demonstrates a number of successful outreach activities centred around radiation detection and described in this paper, focusing on activities delivered to a variety of audiences and related to applied nuclear physics work within our group. These concentrate on the application of novel sensor technologies for nuclear decommissioning, medical imaging modalities and the monitoring of environmental radioactivity. The paper will provide some necessary background material as well as practical instructions for some of the activities developed.

A comparative study of selected Georgia elementary principals' perceptions of environmental knowledge

NASA Astrophysics Data System (ADS)

Campbell, Joyce League

This study sought to establish baseline data on environmental knowledge, opinions, and perceptions of elementary principals and to make comparisons based on academic success rankings of schools and to national results. The self-reported study looked at 200 elementary principals in the state of Georgia. The population selected for the study included principals from the 100 top and 100 bottom academically ranked elementary schools as reported in the Georgia Public Policy Foundation Report Card for Parents. Their scores on the NEETF/Roper Environmental Knowledge Survey were compared between these two Georgia groups and to a national sample. Georgia elementary principals' scores were compared to environmental programs evident in their schools. The two Georgia groups were also compared on environmental opinion and perception responses on mandates, programs in schools and time devoted to these, environmental education as a priority, and the impact of various factors on the strength of environmental studies in schools. Georgia elementary principals leading schools at the bottom of the academic performance scale achieved environmental knowledge scores comparable to the national sample. However, principals of academically successful schools scored significantly higher on environmental knowledge than their colleagues from low performing schools (p < .05) and higher than the national sample (p < .001). Both Georgia principal groups strongly support a mandated environmental education curriculum for Georgia. The two groups were comparable on distributions of time devoted to environmental education across grade levels; however, principals from the more successful schools reported significantly (p < .01) greater amounts of time allotted to environmental studies. Both groups reported the same variety of environmental programs and practices evident in their schools and similar participation in these activities at various grade levels. Most significant (p < .01) was the comparison of ratings each group gave to environmental education as an instructional priority in their schools; principals supervising successful school programs viewed environmental education as a higher priority. These successful principals also recognized the importance of both administrator and staff interest as influencing factors and ranked these two variables as strongly impacting the success or failure of environmental initiatives in schools. Comparison of principals' environmental knowledge scores to numbers of programs shown no significant relationship. (Abstract shortened by UMI.)

During summers 2011 and 12 Montclair State University hosted a Research Experience for Undergraduates Program (REU) in transdisciplinary, hands-on, field-oriented research in environmental sciences. Participants were housed at the Montclair State University's field station situated in the middle of 30,000 acres of mature forest, mountain ridges and freshwater streams and lakes within the Kittatinny Mountains of Northwest New Jersey, Program emphases were placed on development of project planning skills, analytical skills, creativity, critical thinking and scientific report preparation. Ten students were recruited in spring with special focus on recruiting students from underrepresented groups and community colleges. Students were matched with their individual research interests including hydrology, erosion and sedimentation, environmental chemistry, and ecology. In addition to research activities, lectures, educational and recreational field trips, and discussion on environmental ethics and social justice played an important part of the program. The ultimate goal of the program is to facilitate participants' professional growth and to stimulate the participants' interests in pursuing Earth Science as the future career of the participants.

Bridging the gap: academic and practitioner perspectives to identify early career competencies needed in healthcare management.

Healthcare organizations, health management professional associations, and educational institutions have begun to examine carefully what it means to be a fully competent healthcare executive. As a result, an upsurge in interest in healthcare management competencies has been observed recently. The present study uses two critically important groups of informants as participants: health management practitioners and faculty. Using the nominal group process, health administrators identified critical environmental issues perceived to have an impact on healthcare executives today. These issues were employed in a card-sort assessment and a survey was administered to a nationwide sample of health administrators. These data were used to create a map and five clusters of the environmental landscape of healthcare management. These clusters of environmental issues provided a framework for having groups of administrators and faculty members generate and rank perceived behavioral competencies relative to each cluster. Implications for healthcare management practice, education, and research are discussed.

The Meeting consisted of 9 Symposia, 4 Keynote Lectures, 3 Platform Sessions and 4 Poster Sessions. In addition there were Breakfast Meetings for Special Interest Groups designed to inform attendees about the latest advances in environmental mutagenesis research. Several of the topics to be covered at this broad meeting will be of interest to the Department of Energy, Office of Science. The relevance of this meeting to the DOE derives from the fact that low dose radiation may represent one of the most significant sources of human mutations that are attributable to the environment. The EMS membership, and those whomore » attended the EMS Annual Meeting were interested in both chemical and radiation induced biological effects, such as cell death, mutation, teratogenesis, carcinogenesis and aging. These topics thate were presented at the 2004 EMS Annual meeting that were of clear interest to DOE include: human variation in cancer susceptibility, unusual mechanisms of mutation, germ and stem cell mutagenesis, recombination and the maintenance of genomic stability, multiple roles for DNA mismatch repair, DNA helicases, mutation, cancer and aging, Genome-wide transcriptional responses to environmental change, Telomeres and genomic stability: when ends don?t meet, systems biology approach to cell phenotypic decision processes, and the surprising biology of short RNAs. Poster and platform sessions addressed topics related to environmental mutagen exposure, DNA repair, mechanisms of mutagenesis, epidemiology, genomic and proteomics and bioinformatics. These sessions were designed to give student, postdocs and more junior scientists a chance to present their work.« less

Worksite Environmental Interventions for Obesity Prevention and Control: Evidence from Group Randomized Trials.

PubMed

Fernandez, Isabel Diana; Becerra, Adan; Chin, Nancy P

2014-06-01

Worksites provide multiple advantages to prevent and treat obesity and to test environmental interventions to tackle its multiple causal factors. We present a literature review of group-randomized and non-randomized trials that tested worksite environmental, multiple component interventions for obesity prevention and control paying particular attention to the conduct of formative research prior to intervention development. The evidence on environmental interventions on measures of obesity appears to be strong since most of the studies have a low (4/8) and unclear (2/8) risk of bias. Among the studies reviewed whose potential risk of bias was low, the magnitude of the effect was modest and sometimes in the unexpected direction. None of the four studies describing an explicit formative research stage with clear integration of findings into the intervention was able to demonstrate an effect on the main outcome of interest. We present alternative explanation for the findings and recommendations for future research.

Classroom Simulation of United Nations Conference on Climate Change

2009-12-01

Global climate change is widely recognized as the most important environmental problem today that requires complex, global solutions with international cooperation. Teaching the science of climate change is relatively simple compared to the challenges of determining solutions to this problem. It is important for students to learn that solutions do exist and that international negotiations are underway to achieve reductions. What are the (policy) solutions to this vexing problem, which countries should take responsibility, and specifically how can this be done? In the final week of an advanced undergraduate environmental science class: Global Environmental Change, students engage in a week-long classroom simulation of the annual United Nations Framework Convention on Climate Change Conference of the Parties (UNFCCC/COP). Small groups of students represent one nation that has a particular, and important, interest in the negotiations. Each group researches the positions their country has with respect to the negotiations, determines their possible allies, and who might have interests that are in conflict with their country. While NGOs such as environmental organizations and industry groups are not formally represented, I include some of these groups since they are influential and provide interesting insight into different interests. For simplicity, about 8-10 nations and NGOs are included. In preparation for the conference, students produce a background paper and draft resolution. At the end of the conference, they refine these documents to produce an updated position paper and resolution on how to mitigate global warming. Students are asked to focus on: 1. How much to change global greenhouse gas emissions over the next decade and over the next century; 2. How much of these emission reductions their country should be responsible for; 3. How will their country meet these goals? They must focus on whether and how to implement two mechanisms: a) Clean Development Mechanisms (specifically whether forests should be used as a carbon sink); and b) emissions trading. Informal negotiations (often at a local café) are included in an effort to make the process more realistic. Fact or Fiction? This exercise is largely on reality, but some of it will be fictitious. While I encourage students to base arguments and proposals on real, documented information I encourage them to develop creative and innovative proposals. This exercise relies on educational material and resources designed for Model United Nations simulations; numerous on-line resources are available for students. At the end of the exercise both science and non-science students have enjoyed immersing themselves in challenging questions that confronts all practitioners of climate policy. This approach gives traditional science students an opportunity to experience the challenges and problems associated with implementing policy solutions, and allows those with interests in policy to explore their interests in depth. Rather than a static, text-oriented approach, students engage in active learning, which is appropriate for this quickly evolving subject. Details of classroom logistics, assessment tools, and handouts will be provided.

Effect of environmental enrichment devices on behaviors of single- and group-housed squirrel monkeys (Saimiri sciureus)

NASA Technical Reports Server (NTRS)

Spring, S. E.; Clifford, J. O.; Tomko, D. L.

1997-01-01

Squirrel monkeys display an interest in novel places, habituate to new situations, and spend most of their daily activity in the wild in large groups engaging in feeding behaviors over a broad area. Captivity limits these behaviors and consequently may disrupt normal social organizations. In captivity, squirrel monkeys may exhibit stereotypical behaviors that are believed to indicate decreased psychologic well-being. When a monkey's behavior can be made to approach that seen in the wild, and stereotypical behaviors are minimal, it is assumed that psychologic well-being is adequate. Environmental enrichment devices have been used to address the Animal Welfare Act requirement that psychologic well-being of captive nonhuman primates be considered. The purpose of the study reported here was to examine whether various environmental enrichment devices improve the psychologic well-being of captive squirrel monkeys. In the study, we used behavioral observation to quantify the effectiveness of several environmental enrichment devices for reducing stereotypical behaviors in squirrel monkeys housed alone or in groups. Analysis of our results revealed that the environmental enrichment devices did not affect the expression of normal or stereotypical behaviors, but that the type of housing did.

The Psychology of Climate Change Communication - Insights from the Center for Research on Environmental Decisions (CRED) (Invited)

NASA Astrophysics Data System (ADS)

Marx, S.

2010-12-01

Natural scientists have made great strides in recent years to improve their understanding of the complex issue of global climate change. Despite the progress made, there continues to be a persistent gap between the knowledge and concern among members of the climate science community and translation of such scientific expertise into effective climate change policies and the general public’s behavioral choices. Communication is breaking down at the intersection of climate science, policy, and behavior change. Part of the reason is that, to date, social science research has not been sufficiently exploited to help individuals and groups incorporate information about climate change and environmental risk into decision making. The presentation will highlight research conducted at the Center for Research on Environmental Decisions (CRED). This presentation will discuss barriers to behavioral change and provide suggestions for improving communication about climate change: Typical science communication requires analytic processing, some level of expertise, at a minimum interest. For most people abstract information does not translate into powerful vivid images that would trigger action. Furthermore, we have found that people’s interpretation of scientific uncertainty can get in the way of using forecasts and projections. Other barriers include public risk perceptions and attitudes, cultural values, and myopia, as well as the importance that people place on self-interest/economic goals vs. collective interest/social goals. Many of these obstacles can be overcome and communication of climate change information can be improved by presenting a combination of affective information (vicarious experience, scenarios, narratives, and analogies) and scientific data; yet there are also downsides to the overuse of emotional appeals (such as the finite pool of worry and the single action bias); tapping into social affiliations and group identities can motivate the activation of social goals in favor or self interest; early involvement of stakeholders through participatory processes can help identify key concerns and information needs which can then be addressed in a tailored approach; taking advantage of default effects can make it easier for people to choose environmentally and socially beneficial options. Using research into the reactions of groups as disparate as African farmers and conservative U.S. voters, we offer insights on how scientists, educators, journalists and others can effectively connect with wider audiences. The communication principles presented in this talk can be applied beyond climate change and to science communication in general.

For Better or For Worse: Environmental Health Promotion in ...

EPA Pesticide Factsheets

Environmental Health Education (EHE) is most effective when it incorporates environmental science, risk education, and health education. When paired with the local knowledge of community members, EHE can promote health equity and community action, especially for socially disadvantaged communities, which are disproportionately exposed to environmental hazards. Developing EHE programs that inform residents about toxic exposures that damage their health and affect their quality of life is critical for them to understand their true risk. The community of interest is a public housing development surrounded by landfills, hazardous waste sites, and manufacturing facilities located in a Midwestern city of the United States (Chicago, Illinois). An environmental justice organization, People for Community Recovery (PCR), was the community partner. Data was collected during one week in March 2009 from community residents using both qualitative and quantitative research methods, including both a focus group and a survey instrument provided to two different resident groups, to understand their attitudes/beliefs about environmental hazards, including exposure to hazardous wastes, landfills, and lead, and their preferences for EHE. The data was analyzed using standard qualitative analytical procedures and statistical software, when appropriate. This research assesses the impact that Environmental Health Education (EHE) can have on: improved civic engagement (i.e., increased int

GLIMPSE is a effort in which the U.S. EPA Office of Research and Development is developing tools to support long-term, coordinated environmental, climate, and energy planning. The purpose of this presentation is to discuss the underlying science questions; provide an overview of current and future GLIMPSE capabilities; introduce GCAM, the computational engine behind GLIMPSE; and, highlight relevant activities in China, including the ABaCAS framework and GCAM-China. A group of Chinese visitors will be on the EPA RTP campus July 28, 9-noon. The visitors are from the PowerChina Huadong Engineering Corporation (weblink is here: http://www.ecidi.com/en/introduction.aspx) and are in US for a training program at Duke. The group is interested in broad management topics such as international business development and managing environmental projects as well as interacting with practitioners to understand “real world” case studies and issues. Their background is primarily related to hydro power but their corporate mission is “Providing engineering services and promoting harmonious development between Man and Nature,” implying a broad interest in the environment. Several researchers with projects with connections to China have been asked to provide an overview of their research to the visitors. I will be talking about the GLIMPSE air-climate-energy decision support project.

Evaluating environmental and economic consequences of alternative pest management strategies: results of modeling workshops

The model conceptualized at the first workshop simulates the effect of corn agrecosystem decisions on crop production, economic returns, and environmental indicators. The model is composed of five interacting submodels: 1) a Production Strategies submodel which makes decisions concerning tillage, planting, fertilizer and pesticide applications, and harvest; 2) a Hydrology/Chemical Transport submodel which represents soil hydrology, erosion, and concentrations of fertilizers and pesticides in the soil, runoff, surface waters, and percolation; 3) a Vegetation submodel which simulates growth of agricultural crops (corns and soybeans) and weeds; 4) a Pests submodel which calculates pest population levels and resulting crop damage; and 5) an Environmental Effects submodel which calculates indicators of potential fish kills, human health effects, and wildlife habitat. The most persistent data gaps encountered in quantifying the model were coefficients to relate environmental consequences to alternative pest management strategies. While the model developed in the project is not yet accurate enough to be used for real-world decisions about the use of pesticides on corn, it does contain the basic structure upon which such a model could be built. More importantly at this stage of development, the project has shown that very complex systems can be modeled in short periods of time and that the process of building such models increases understanding among disciplinary specialists and between diverse institutional interests. This process can be useful to EPA as the agency cooperates with other institutions to meet its responsibilities in less costly ways. Activities at the second 2 1/2-day workshop included a review of the model, incorporation of necessary corrections, simulation of policy scenarios, and examination of techniques to address remaining institutional conflicts. Participants were divided into three groups representing environmental, production or industry, and regulatory interests. Each group developed scenarios that would be most appealing to their particular interest and the scenarios were simulated by the agroecosystem computer model. Negotiators from each of the interest groups decided whether a hypothetical herbicide should be relabeled and if certain restrictions should be imposed on its use. Other participants functioned as experts and consultants on caucus teams. A solution to the hypothetical problem was successfully negotiated. Workshop participants and project staff agreed that the model and processes developed during the project should be used in training students, extension specialists, farmers, researchers, and chemical producers in collaborative problem solving methods. More productive research can be planned, and more realistic models of complex systems can be built in this way. More importantly, greater trust of decisionmakers in computer models, better understanding by technical experts about disciplines other than their own, and improved cooperation between institutional interests can be achieved. This trust, understanding, and cooperation are critical ingredients in solving problems that are too complex to be resolved by independent disciplinary activity and unilateral decision authority.

Multicriteria decision analysis applied to Glen Canyon Dam

USGS Publications Warehouse

Flug, M.; Seitz, H.L.H.; Scott, J.F.

2000-01-01

Conflicts in water resources exist because river-reservoir systems are managed to optimize traditional benefits (e.g., hydropower and flood control), which are historically quantified in economic terms, whereas natural and environmental resources, including in-stream and riparian resources, are more difficult or impossible to quantify in economic terms. Multicriteria decision analysis provides a quantitative approach to evaluate resources subject to river basin management alternatives. This objective quantification method includes inputs from special interest groups, the general public, and concerned individuals, as well as professionals for each resource considered in a trade-off analysis. Multicriteria decision analysis is applied to resources and flow alternatives presented in the environmental impact statement for Glen Canyon Dam on the Colorado River. A numeric rating and priority-weighting scheme is used to evaluate 29 specific natural resource attributes, grouped into seven main resource objectives, for nine flow alternatives enumerated in the environmental impact statement.

The influence and ethics of interest groups on policy incentives for clean energy development

NASA Astrophysics Data System (ADS)

Maguire, Mariana C.

The clean energy revolution in the United States is not going to happen until diverse stakeholders in the coalition of clean energy proponents strengthen their cohesion and influence—two critical tools for interest group's to be successful in driving the formulation of public policy. Currently, clean energy technology and resource development is supported by a highly diverse coalition of interest groups such as environmental groups, health organizations, industry, and the Defense Department, whose primary goals are often unrelated. Yet their objectives are increasingly well served by pursuing clean energy development by pushing lawmakers for supportive policies. However, characteristics of this ad hoc coalition can hinder its influence and cohesion. Whereas, fossil fuel interests—exemplified by the coalition of oil proponents—are highly cohesive and influential. This thesis will analyze whether there is a correlation between public policies on clean energy, and the strength of interest group influence over those policy decisions. It will begin with an analysis of interest group theories. Next it will analyze the histories of the oil industry as the model opponent of clean energy policies, and the biofuels, wind energy, and solar energy industries as the model proponents of clean energy policies. The composition of the respective coalitions will reveal if they are diverse or similar, with broad or narrow goals, and other important characteristics. Their respective policy positions and messages will show what values are important to them, and the presidential support each coalition has been achieved, or failed to achieve, will provide further insight into their effectiveness. This thesis will then apply interest group theories to the supporter and opponent coalitions. Results obtained indicate that the coalition of oil interests is large, yet very cohesive and influential, while the coalition for clean energy is large, generally diffuse but with some important signs of cohesion, and relatively influential. Therefore this analysis concludes that the clean energy coalition must strengthen itself in areas that produce cohesion, such as encouraging partnerships with stakeholders with asymmetrical interests, and increase its financial influence in order to leverage more resources toward influencing policymakers to promote clean energy development.

Protecting the Environment for Self-interested Reasons: Altruism Is Not the Only Pathway to Sustainability.

PubMed

De Dominicis, Stefano; Schultz, P Wesley; Bonaiuto, Marino

2017-01-01

Concerns for environmental issues are important drivers of sustainable and pro-environmental behaviors, and can be differentiated between those with a self-enhancing (egoistic) vs. self-transcendent (biospheric) psychological foundation. Yet to date, the dominant approach for promoting pro-environmental behavior has focused on highlighting the benefits to others or nature, rather than appealing to self-interest. Building on the Inclusion Model for Environmental Concern, we argue that egoistic and biospheric environmental concerns, respectively, conceptualized as self-interest and altruism, are hierarchically structured, such that altruism is inclusive of self-interest. Three studies show that self-interested individuals will behave more pro-environmentally when the behavior results in a personal benefit (but not when there is exclusively an environmental benefit), while altruistic individuals will engage in pro-environmental behaviors when there are environmental benefits, and critically, also when there are personal benefits. The reported findings have implications for programs and policies designed to promote pro-environmental behavior, and for social science research aimed at understanding human responses to a changing environment.

This dissertation explores the claim that the energy problem involves a basic conflict of values between representatives of economic interests and of the public. Economic interests define the energy problems in narrow economic and technological terms, while public interests define the problem in broad societal and environmental terms. Ideological and policy positions have polarized around the following transientific problems: equity for present and future generations; the level of risk a society should take; tradeoff between laissez faire freedom and freedom and human rights to health, safety and environmental integrity, and, finally, who should decide, citizen or expert. The study ismore » based, in large part, on original materials - correspondence, interviews, reports and questionnaires - from a 4-year study on energy and values conducted by the National Council of Churches in which the author was a participant observer. The study process involved major US institutions - industry, government, labor, university, religion, and related spokespersons in the public-interest community. Findings indicate that both sides, frustrated by government bureaucracy, have designed alternative structures and techniques to resolve conflicts and expedite their goals, e.g., flexible ad hoc groups and mediation.« less

The ecology of cooperative breeding behaviour.

PubMed

Shen, Sheng-Feng; Emlen, Stephen T; Koenig, Walter D; Rubenstein, Dustin R

2017-06-01

Ecology is a fundamental driving force for the evolutionary transition from solitary living to breeding cooperatively in groups. However, the fact that both benign and harsh, as well as stable and fluctuating, environments can favour the evolution of cooperative breeding behaviour constitutes a paradox of environmental quality and sociality. Here, we propose a new model - the dual benefits framework - for resolving this paradox. Our framework distinguishes between two categories of grouping benefits - resource defence benefits that derive from group-defended critical resources and collective action benefits that result from social cooperation among group members - and uses insider-outsider conflict theory to simultaneously consider the interests of current group members (insiders) and potential joiners (outsiders) in determining optimal group size. We argue that the different grouping benefits realised from resource defence and collective action profoundly affect insider-outsider conflict resolution, resulting in predictable differences in the per capita productivity, stable group size, kin structure and stability of the social group. We also suggest that different types of environmental variation (spatial vs. temporal) select for societies that form because of the different grouping benefits, thus helping to resolve the paradox of why cooperative breeding evolves in such different types of environments. © 2017 John Wiley & Sons Ltd/CNRS.

A Rorschach comparison of psychopaths, sexual homicide perpetrators, and nonviolent pedophiles: where angels fear to tread.

PubMed

Gacono, C B; Meloy, J R; Bridges, M R

2000-06-01

Nonsexually offending psychopaths (N = 32) were compared to sexual homicide perpetrators (N = 38) and nonviolent pedophiles (N = 39) on select Comprehensive System Rorschach variables (Exner et al., 1993). Results indicate similarities among the groups in pathological narcissism, formal thought disorder, and borderline level reality testing. Nonsexually offending psychopaths are distinguished by their lack of interest in and attachment to others and their seemingly conflict-free internal world. While both sexually deviant groups evidenced interest in others and appear to experience a very dysphoric internal world, the sexual homicide perpetrators are distinguished by high levels of obsessional thought and an inability to disengage from environmental stimuli. Pedophiles show significantly more characterological anger, which may stem from their general inadequacy, cognitive rigidness, less alloplastic (acting out) style, and their introversive inability to gratify their needs. Rorschach differences add to our understanding of sexual deviation and violence among these three groups.

Values and public acceptability dimensions of sustainable egg production.

2011-09-01

The attributes of egg production that elicit values-based responses include the price and availability of eggs, environmental impacts, food safety or health concerns, and animal welfare. Different social groups have distinct interests regarding the sustainability of egg production that reflect these diverse values. Current scientifically based knowledge about how values and attitudes in these groups can be characterized is uneven and must be derived from studies conducted at varying times and using incomplete study methods. In general, some producer and consumer interests are translated through markets and are mediated by market mechanisms, whereas others are poorly reflected by economic behavior. An array of survey and focus group research has been performed to elicit consumer and activist beliefs about performance goals they would expect from an egg production system. These studies provide evidence that consumers' market behavior may be at odds with their ethical and political beliefs about performance goals.

The Residence for Earth and Environmental Living and Learning (REELL), a residential learning community (RLCs) established at the University of the Pacific in 2008-2009, has proven to be an effective tool for increasing interest in the Earth and environmental sciences. RLCs bring together students that share a theme-based interest and are given an opportunity to live together in a common space within a campus residence hall. The 2008-2009 REELL group comprised representatives from a wide range of degree programs, and included 16 freshmen, a junior peer advisor, and a senior residential advisor. Student participants in the REELL community work closely with their peers, faculty, and staff on academic, social, and outreach programs designed to increase interest and awareness in the Earth & environment. REELL activities include regular meetings, sponsored movies, guest speakers, field trips, campus exchange events, and outreach activities. These activities are arranged around a yearlong research project that is designed and implemented by the student participants. Preliminary results suggest that activity- and project-related interactions during the 2008-2009 REELL program year are an effective way to establish connections between among students, faculty, and administration and have increased interest and participation in Earth and Environmental Science courses and programs. Studies of RLCs implemented in a wide variety of colleges and university settings demonstrate that these programs successfully foster the development of leadership, social, and academic skills in student participants. The REELL community at the University of the Pacific is based upon the successful the Honors RLC. The well-established Honors RLC is a perfect example of how such programs can increase social and academic development. Like the REELL program, the Honors RLC brings together first and second year honors students in a single residence hall. Their participation in the Honors RLC provides education experiences for the whole person outside of the classroom.

The effect of mine drainage effluent on aquatic ecosystems has been abundantly documented and remediation efforts to data have always been costly and temporary at best. Bioremediation, using natural environmental microbes, to treat acid mine drainage has shown great promise as an affordable, permanent treatment. At Lambda, we used mixatrophic cultures of bacteria, algae, protozoans and fungal groups on four different jobs and it has proven effective. The role of two particular algal groups, the Euglena mutabilis and the Ochramonas sp. are particularly of phycological interest.

This is a descriptive study examining nursing students' perceptions of the environmental risks and their environmental attitudes. The study population comprised 2364 nursing students studying at universities in Istanbul in the fall semester of the 2012-2013 academic year. The sampling group was formed by 778 students which were selected by a stratified random sampling procedure. The data were collected using "The Student Personal Information Form", "The Environmental Risk Perception Scale" and "The Environmental Attitudes Scale". The students' mean score on perceptions of environmental risk was 6.04 ± 0.81(min 2.56; max 7.00) and the mean score of their environmental attitudes was 4.02 ± 0.47(min 2.28; max 5.00). It was determined that factors such as gender, interest in environmental issues, endorsement of the college course on environment as necessary, and participation in an environmental activity and awareness of non-government environmental organizations affected the environmental risk perception and environmental attitudes. A moderate positive relationship (r = 0.366, p < .001) was found between the students' environmental risk perceptions and their environmental attitudes. Effective environmental education should be planned at all stages of the nursing education.

Visitor interest in zoo animals and the implications for collection planning and zoo education programmes.

PubMed

Moss, Andrew; Esson, Maggie

2010-01-01

As zoos have sought to further their conservation missions, they have become powerful providers of environmental education. Outside of "formal" education initiatives, such as those designed for school and other organized groups, or structured public talks programmes, much of the learning potential that the zoo has to offer is around the viewing of animals and the response of visitors to them. In this, zoo learning is a very personal construct, develops from the previous knowledge, and experiences and motivations of each individual. In this article, we make the assertion that learning potential, although difficult to quantify, is very much related to the attractiveness of animal species and the interest that visitors show in them. Using standard behaviorist measures of attraction and interest (the proportion of visitors that stop and for how long), we analyzed the relative interest in 40 zoo species held in a modern UK zoo and the variables that are significant in predicting that popularity. Further to this, the suggestion is made that the zoo collection planning process could use such information to make more informed decisions about which species should be housed for their educational value. Taxonomic grouping was found to be the most significant predictor of visitor interest--that is, visitors were far more interested in mammals than any other group--although body size (length), increasing animal activity and whether the species was the primary or "flagship" species in an exhibit or not, were all found to have a significant bearing on visitor interest. © 2010 Wiley-Liss, Inc.

The influence of the environmental management system on the environmental impact of seaport companies during an economic crisis: Lithuanian case study.

Freight handling in EU ports fell by more than 12 % during the global economic crisis in 2008-2009 after almost a decade of continuous growth. The decrease of freight handling in the Klaipeda seaport, the only port in Lithuania, was 6.7 % and happened due to the dominant outward movement of goods (mainly oil products). The Klaipeda seaport, due to its peculiarity, is the only ice-free port in the northern part of Baltic Sea. The present study explores the environmental impact of Klaipeda seaport activities from 2001 to 2011. Moreover, it compares the environmental effectiveness of environmental protection strategies used in the four biggest companies that, in fact, cover about 88 % of total activities (except general cargo) of the seaport. The first group of targeted companies used an environmental protection strategy to implement an ISO 14001-based environmental management system, and the second group selected to follow environmental management practices without certification. The paper analyses the development of the companies' activities in regard to the change of environmental effectiveness. The paper evaluates the pressure of the economic crisis on the companies' activities and its influence on environmental decisions, with particular interest in the ability of different environmental protection systems to resist and handle the expected performance. The study identified a significant decrease in companies' activities during the crisis period. However, the economic activities and environmental effectiveness demonstrated similar short-term tendencies in regard to the environmental strategy selection but differed in long-term perspective.

Water demand management in Yemen and Jordan: addressing power and interests.

Zeitoun, Mark; Allan, Tony; Al Aulaqi, Nasser; Jabarin, Amer; Laamrani, Hammou

2012-01-01

This paper investigates the extent to which entrenched interests of stakeholder groups both maintain water use practice, and may be confronted. The focus is on the agricultural sectors of Yemen and Jordan, where water resource policymakers face resistance in their attempts to reduce water use to environmentally sustainable levels through implementation of water demand management (WDM) activities. Some farmers in both countries that have invested in irrigated production of high-value crops (such as qat and bananas) benefit from a political economy that encourages increased rather than reduced water consumption. The resultant over-exploitation of water resources affects groups in unequal measures. Stakeholder analysis demonstrates that the more ‘powerful’ groups (chiefly the large landowners and the political elites, as well as the ministries of irrigation over which they exert influence) are generally opposed to reform in water use, while the proponents of WDM (e.g. water resource managers, environmental ministries and NGOs, and the international donor community) are found to have minimal influence over water use policy and decisionmaking. Efforts and ideas attempted by this latter group to challenge the status quo are classified here as either (a) influencing or (b) challenging the power asymmetry, and the merits and limits of both approaches are discussed. The interpretation of evidence suggests current practice is likely to endure, but may be more effectively challenged if a long-term approach is taken with an awareness of opportunities generated by windows of opportunity and the participation of ‘overlap groups’.

The JPL Workshop addressed a number of plasma issues that bear on advanced spaceborne technology for the years 2000 and beyond. Primary interest was on the permanently manned space station with a focus on identifying environmentally related issues requiring early clarification by spaceborne plasma experimentation. The Beams Working Group focused on environmentally related threats that platform operations could have on the conduct and integrity of spaceborne beam experiments and vice versa. Considerations were to include particle beams and plumes. For purposes of definition it was agreed that the term particle beams described a directed flow of charged or neutral particles allowing single-particle trajectories to represent the characteristics of the beam and its propagation. On the other hand, the word plume was adopted to describe a multidimensional flow (or expansion) of a plasma or neutral gas cloud. Within the framework of these definitions, experiment categories included: (1) Neutral- and charged-particle beam propagation, with considerations extending to high powers and currents. (2) Evolution and dynamics of naturally occurring and man-made plasma and neutral gas clouds. In both categories, scientific interest focused on interactions with the ambient geoplasma and the evolution of particle densities, energy distribution functions, waves, and fields.

Is Earth F**ked? Dynamical Futility of Global Environmental Management and Possibilities for Sustainability via Direct Action Activism

NASA Astrophysics Data System (ADS)

wErnEr, B.

2012-12-01

Environmental challenges are dynamically generated within the dominant global culture principally by the mismatch between short-time-scale market and political forces driving resource extraction/use and longer-time-scale accommodations of the Earth system to these changes. Increasing resource demand is leading to the development of two-way, nonlinear interactions between human societies and environmental systems that are becoming global in extent, either through globalized markets and other institutions or through coupling to global environmental systems such as climate. These trends are further intensified by dissipation-reducing technological advances in transactions, communication and transport, which suppress emergence of longer-time-scale economic and political levels of description and facilitate long-distance connections, and by predictive environmental modeling, which strengthens human connections to a short-time-scale virtual Earth, and weakens connections to the longer time scales of the actual Earth. Environmental management seeks to steer fast scale economic and political interests of a coupled human-environmental system towards longer-time-scale consideration of benefits and costs by operating within the confines of the dominant culture using a linear, engineering-type connection to the system. Perhaps as evidenced by widespread inability to meaningfully address such global environmental challenges as climate change and soil degradation, nonlinear connections reduce the ability of managers to operate outside coupled human-environmental systems, decreasing their effectiveness in steering towards sustainable interactions and resulting in managers slaved to short-to-intermediate-term interests. In sum, the dynamics of the global coupled human-environmental system within the dominant culture precludes management for stable, sustainable pathways and promotes instability. Environmental direct action, resistance taken from outside the dominant culture, as in protests, blockades and sabotage by indigenous peoples, workers, anarchists and other activist groups, increases dissipation within the coupled system over fast to intermediate scales and pushes for changes in the dominant culture that favor transition to a stable, sustainable attractor. These dynamical relationships are illustrated and explored using a numerical model that simulates the short-, intermediate- and long-time-scale dynamics of the coupled human-environmental system. At fast scales, economic and political interests exploit environmental resources through a maze of environmental management and resistance, guided by virtual Earth predictions. At intermediate scales, managers become slaved to economic and political interests, which adapt to and repress resistance, and resistance is guided by patterns of environmental destruction. At slow scales, resistance interacts with the cultural context, which co-evolves with the environment. The transition from unstable dynamics to sustainability is sensitively dependent on the level of participation in and repression of resistance. Because of their differing impact inside and outside the dominant culture, virtual Earth predictions can either promote or oppose sustainability.

Transboundary environmental assessment: lessons from OTAG. The Ozone Transport Assessment Group.

PubMed

Farrell, Alexander E; Keating, Terry J

2002-06-15

The nature and role of assessments in creating policy for transboundary environmental problems is discussed. Transboundary environmental problems are particularly difficult to deal with because they typically require cooperation among independent political jurisdictions (e.g., states or nations) which face differing costs and benefits and which often have different technical capabilities and different interests. In particular, transboundary pollution issues generally involve the problem of an upstream source and a downstream receptor on opposite sides of a relevant political boundary, making it difficult for the jurisdiction containing the receptor to obtain relief from the pollution problem. The Ozone Transport Assessment Group (OTAG) addressed such a transboundary problem: the long-range transport of tropospheric ozone (i.e., photochemical smog) across the eastern United States. The evolution of the science and policy that led to OTAG, the OTAG process, and its outcomes are presented. Lessons that are available to be learned from the OTAG experience, particularly for addressing similar transboundary problems such as regional haze, are discussed.

The Canadian experience in frontier environmental protection

1991-03-01

Early Canadian frontier exploration (from 1955 onshore and from 1966 for offshore drilling) caused insignificant public concern. The 1967-1968 Torrey Canyon Tanker and Santa Barbara disasters roused public opinion and governments. In Canada, 1969-1970 Arctic gas blowouts, a tanker disaster, and damage to the 'Manhattan' exacerbated concerns and resulted in new environmental regulatory constraints. From 1970, the Arctic Petroleum Operations Association learned to operate safely with environmental responsibility. It studied physical environment for design criteria, and the biological and human environment to ameliorate impact. APOA's research projects covered sea-ice, permafrost, sea-bottom, oil-spills, bird and mammal migration, fish habitat, food chains,more » oceanography, meteorology, hunters'/trappers' harvests, etc. In 1971 Eastcoast Petroleum Operators' Association and Alaska Oil and Gas Association followed APOA's cooperative research model. EPOA stressed icebergs and fisheries. Certain research was handled by the Canadian Offshore Oil Spill Research Association. By the mid-1980s these associations had undertaken $70,000,000 of environmental oriented research, with equivalent additional work by member companies on specific needs and similar sums by Federal agencies often working with industry on complementary research. The frontier associations then merged with the Canadian Petroleum Association, already active environmentally in western Canada. Working with government and informing environmental interest groups, the public, natives, and local groups, most Canadian frontier petroleum operations proceeded with minimal delay and environmental disturbance.« less

In this commentary on Nye, Su, Rounds, and Drasgow (2012) and Schmidt (2011), I address the value of occupational interest inventories for understanding sex differences in occupational choice and the extent to which occupational interests are malleable. In particular, I argue (a) that some subscales in interest inventories are too heterogeneous to be given a single label and that the labels that are applied to some subscales are inaccurate and misleading; (b) that "things versus people" is an inaccurate and misleading characterization of a dimension that is frequently associated with interest inventories and linked to sex differences; (c) that vocational interests will be valid predictors of job performance primarily in cases in which the job has been held for some time by a diverse group of people and not in cases in which jobholders have been homogeneous; (d) that sex differences in interests are malleable and sensitive to small and subtle environmental cues; and (e) that women's interest in math and science will increase if they have a feeling of belonging and an expectation of success. © The Author(s) 2014.

Moving beyond Green: Exploring the Relationship of Environment Type and Indicators of Perceived Environmental Quality on Emotional Well-Being following Group Walks

2014-01-01

Against the backdrop of increasing interest in the relationship between Nature and health, this study examined the effect of perceived environment type and indicators of perceived environmental quality on short-term emotional well-being following outdoor group walks. Participants (n = 127) of a national group walk program completed pre- and post-walk questionnaires for each walk attended (n = 1009) within a 13-week study period. Multilevel linear modelling was used to examine the main and moderation effects. To isolate the environmental from the physical activity elements, analyses controlled for walk duration and perceived intensity. Analyses revealed that perceived restorativeness and perceived walk intensity predicted greater positive affect and happiness following an outdoor group walk. Perceived restorativeness and perceived bird biodiversity predicted post-walk negative affect. Perceived restorativeness moderated the relationship between perceived naturalness and positive affect. Results suggest that restorative quality of an environment may be an important element for enhancing well-being, and that perceived restorativeness and naturalness of an environment may interact to amplify positive affect. These findings highlight the importance of further research on the contribution of environment type and quality on well-being, and the need to control for effects of physical activity in green exercise research.

Measures to reinforce the legal liability of the environmental interest subject —Based on the perspective of law and economics

NASA Astrophysics Data System (ADS)

Fa, L. N.

2017-11-01

Local government should be regarded as the main subject to be stipulated by environmental law, thus to avoid local government’s alignment with commercial interests. Such a shift would, furthermore, discourage collusion against environment law or speculative behaviors motivated by maximizing production at the expense of environment pollution. Moreover, whether companies make proactive decisions to prevent pollution or not depends on the severity of appropriate environment legal system’s sanctions for their action. It would encourage enterprises to undertake their own environmental responsibility if environmental law could further enhance their environmental liability. In addition, public environmental rights should be embedded into environmental law. In this way, the public may become more aware of their environmental rights as well as the positivity of total environmental interests.

Typological review of environmental performance metrics (with illustrative examples for oil spill response).

2007-07-01

An intensification of interest in environmental assessment during the last 2 decades has driven corporate efforts to better document environmental goals, improve environmental management systems, and increase awareness of the environmental and ecological effects of business operations. This trend has been motivated partly by regulatory requirements (such as the Toxics Release Inventory in the United States) and partly by the inclination of some large manufacturing firms to embrace a broader social and environmental mission characterized as "sustainability" or "ecoefficiency." Moreover, the importance of measurable objectives in the US government has been recognized at least since the Government Performance Results Act of 1993, which was intended to both improve the efficiency of government and the confidence of the American public in government managers. However, in management of environmental crises - such as catastrophic oil or chemical spills - development of measurable performance standards has lagged. Consequently, government spill managers are unable to define success in terms that are easily communicated to public and other stakeholder groups, and they could be disadvantaged in their efforts to deploy response resources with maximum efficiency. In this paper, we present a typological review of environmental assessment measures and summarize some of the current practices and strategic goals among federal agencies with regard to oil and chemical spills. A general approach to organizing metrics for oil spill response, restoration, and recovery is also presented. The results could improve planning efforts and communication among different federal, state, and local agencies and public or stakeholder groups involved in spill management.

2011-12-01

This is the first genetically informative study in which multiple informants were used to quantify the genetic and environmental sources of individual differences in general interests as well as the phenotypic and genetic links between general interests and Big Five personality traits. Self-reports and two peer ratings from 844 individuals, including 225 monozygotic and 113 dizygotic complete twin pairs, were collected. Multiple-rater scores (composites) revealed that the averaged levels of genetic and environmental effects on seven broad interest domains were similar to those on personality traits. Multivariate analyses showed that about 35% of the genetic and 9% of the environmental variance in interests were explained by personality domains, in particular by Openness. The findings suggest that interests cannot easily be considered as a byproduct of the interactions between personality genotypes and the environmental influences but rather as an internal regulation of behavior with an own genetic basis.

Inaccurate official assessment of radiofrequency safety by the Advisory Group on Non-ionising Radiation.

2016-12-01

The Advisory Group on Non-ionising Radiation (AGNIR) 2012 report forms the basis of official advice on the safety of radiofrequency (RF) electromagnetic fields in the United Kingdom and has been relied upon by health protection agencies around the world. This review describes incorrect and misleading statements from within the report, omissions and conflict of interest, which make it unsuitable for health risk assessment. The executive summary and overall conclusions did not accurately reflect the scientific evidence available. Independence is needed from the International Commission on Non-Ionizing Radiation Protection (ICNIRP), the group that set the exposure guidelines being assessed. This conflict of interest critically needs to be addressed for the forthcoming World Health Organisation (WHO) Environmental Health Criteria Monograph on Radiofrequency Fields. Decision makers, organisations and individuals require accurate information about the safety of RF electromagnetic signals if they are to be able to fulfil their safeguarding responsibilities and protect those for whom they have legal responsibility.

The concepts of "frontal" and "dysexecutive" syndromes are still a matter of debate in the literature. These terms are often used interchangeably but can be distinguished when considering specific frontal behavioural deficits which occur during social interaction. Despite being of interest for the clinical assessment and care management of patients with anterior brain damage, few studies have tried to disentangle the specificity of each syndrome. We report the case of eight patients with frontal lobe damage who were assigned to one of two groups based on whether or not they showed a dysexecutive syndrome. The nondysexecutive group differed from the dysexecutive group in showing environmental dependency phenomena, behavioural disorders triggered by social interaction. By adopting an interactionist perspective, this pilot study contributes to defining more precisely the distinction between "frontal" and "dysexecutive" syndromes. The discussion focuses on the potential interest of the interactionist approach in designing appropriate methodologies of assessment and rehabilitation of patients with frontal lobe syndrome.

An examination of environmental collective identity development across three life-stages: The contribution of social public experiences at zoos

NASA Astrophysics Data System (ADS)

Fraser, John Robert

This research breaks ground toward a revised theory of how collective environmental identity is associated with pro-environmental behaviors. My research comprises three activities that examined the experiences of three groups of people who claim zoo visiting as an important part of their life-story. The three studied groups were; conservation biologists who describe zoo experiences as having significant formative role in their childhood development of environmental values; parents who prioritize zoo visits as an important cultural experiences for their children; and a active zoo volunteers. This research also investigated whether the group experiences these participants had at zoos contributed to the value these people place on their current collective and environmental identities. Field conservationists' interest in learning from animals was validated by parents who also valued education and helped these children develop identities that included other animals in their scope of justice. Parents used zoos instrumentally to promote caring for others as a skill that will serve their children's socio-political future as part of human society. In both cases, these experiences appeared to be shaped around developing attitudes that would include animals in these children's scope of justice in later life. Zoo volunteers included animals in their scope of justice, believing that other species were also important sources of for their knowledge development. Shared positive attitudes toward animals were central to volunteers feeling part of a community and contributing to their collective self-esteem. The group may serve a restorative function in their lives, allowing them to take on a more activist role in society, seeking to promote social norms that are more inclusive of animal rights, and helping them to change their behaviors toward more environmentally responsible ends. This research contributes to the understanding of the theory of planned behavior and the values/beliefs/norms theory by demonstrating that pro-environmental behavior may originate with parenting activities in out-of-home cultural institutions like zoos, and is associated with involvement in social groups at later points in the life-course. It demonstrates that sharing a collective identity like that of a zoo volunteer is associated with engaging in pro-environmental behaviors even before those beliefs and values are fully understood. Although the contribution of parenting and group activity to pro-environmental behaviors demonstrated in this research was small, these results do suggest that focusing on out-of-home support for parents teaching social skills through animal based experiences, and support of activities that promote group attachment for environmentally concerned citizens, may be a possible strategies to advance more environmentally responsible behavior in society for both the short and long term.

In recent years, there has been a significant interest on biochar for various environmental applications, e.g., pollutants removal, carbon sequestration, and soil amelioration. Biochar has several unique properties, which makes it an efficient, cost-effective and environmentally-friendly material for diverse contaminants removal. The variability in physicochemical properties (e.g., surface area, microporosity, and pH) provides an avenue for biochar to maximize its efficacy to targeted applications. This review aims to highlight the vital role of surface architecture of biochar in different environmental applications. Particularly, it provides a critical review of current research updates related to the pollutants interaction with surface functional groups of biochars and the effect of the parameters variability on biochar attributes pertinent to specific pollutants removal, involved mechanisms, and competence for these removals. Moreover, future research directions of biochar research are also discussed. Copyright © 2017 Elsevier Ltd. All rights reserved.

Besides effect and environmental monitoring, human biomonitoring (HBM) offers an attractive method for analyzing the distribution and intensity of anthropogenic environmental pollutants in individuals or in particular groups of the population. However, no assessment values of comparable reliability are available to enable an interpretation of the results of environmental studies from the viewpoint of environmental health. This must be taken into account when reporting findings of such studies as well as in medical consultation, in order to avoid overdiagnosis and unnecessary anxiety for the participant. In medical practice, care should be taken when dealing with monitoring results outside the normal range! Environmental or biomonitoring results provide only a part of the available information alongside medical history and clinical examinations. In the case of tests performed for private interests as well as tests carried out within the framework of an epidemiological environmental survey, communication of results and findings can be problematic. In epidemiological studies, a close co-operation between the participant's consultant physician and physicians conducting the study is beneficial in order to ensure professional advisory counselling for subjects with results outside the normal range.

Scientists interested in contamination normally deal only with pollution itself, not with people's perceptions of pollution or the relationship between pollution and land use. The overall objective of this article was to examine the relationship between people's perceptions of pollution and their views on future land use. People were interviewed at an Earth Day Festival near the Department of Energy's Brookhaven National Laboratory (BNL) on Long Island, New York. On an open-ended question, people thought that BNL should be left as it is, or maintained as a preserve, park or conservation area, or used for environmental research. Almost no one thought that it should be used for housing or industrial purposes. When asked to rate a list of possible future land uses, maintaining BNL as a National Environmental Research Park for research and for recreation were rated the highest (nuclear storage was rated the lowest). This was consistent with the subjects' views that pollution was the greatest concern about BNL. The congruence between perceptions about concerns or problems and future land use preferences suggests a unified view of management of contaminated sites, such as BNL, at least among a group of people whose environmental interests were evident by their presence at the event.

Secrecy vs. the need for ecological information: challenges to environmental activism in Russia.

PubMed

Jandl, T

1998-01-01

This article identifies the lessons learned from the Nikitin case study in Russia. The Nikitin case involves the analysis of sources of radioactive contamination in several Russian counties and in the Russian Northern Fleet. Norway was interested in the issue due to proximity to the storage sites. The issue involved national security and environmental protection. It was learned that mixing national security issues with environmental issues offers dangerous and multiple challenges. Environmental groups must build relationships with a wide audience. International security policy must include the issues of globalization of trade and the spread of environmental problems into the global commons (oceans and atmosphere). The risk of an environmentally dangerous accident as a consequence of Cold War activities is greater than the risk of nuclear war. Secrecy in military affairs is not justified when there is inadequate storage of nuclear weapons and contaminated materials. In Russia, the concern is great due to their economic transition and shortages of funds for even the most basic needs, which excludes nuclear waste clean up. The Bellona Foundation studied the extent of nuclear pollution from military nuclear reactors in the Kola peninsula of northwest Russia, in 1994 and 1996. Russian security police arrested one of the report authors for alleged national security violations. A valuable lesson learned was that local Russian environmental groups needed international support. The military nuclear complex poses an enormous hazard. Limiting inspections is an unacceptable national security risk. The new Russian law on state secrets is too broad.

Development of environmental education in the Korean kindergarten context

Shin, Keum Ho

Many environmental educators insist that environmental education (EE) should be started from a young age. The Korean Ministry of Education (1999) has also emphasized the importance of environmental education in early childhood by including content and objectives regarding EE in the 1999 National Curriculum of Kindergarten. However, many Korean kindergarten teachers do not sufficiently implement environmental education in their teaching practice. To address this issue, this study aimed at investigating and overcoming barriers to fully implement EE in the Korean kindergarten context. Four experienced Korean kindergarten teachers were involved in a fourteen-week critical action research project that included weekly group meetings. At these group meetings, teachers reflected on the barriers preventing the full implementation of EE in their classrooms and discussed possible environmental education actions to be attempted in the following week. These actions, individually implemented in teachers' classrooms, were reviewed at subsequent group meetings. Data from group meetings and teacher lessons were used to analyze the effectiveness of this critical action research project for developing environmental education. At the beginning stages of this study, Korean kindergarten teachers felt strongly uncomfortable participating in group communication. However, through the continuous encouragement of the researcher and with the involvement of participants who have similar educational backgrounds, age, and working experiences, participants came to actively engage in group communication. Participants in this study identified the following barriers to fully implement EE in kindergartens: insufficient understandings and awareness of EE, reluctant attitudes towards the environment, lack of educational support and resources, low parental involvement, and discomfort about going on a field trip to environments. Teachers came to understand the importance, objectives, potential topics, and teaching methods of early childhood environmental education. While implementing environmental education in their classrooms, teachers recognized possibilities for environmental education through connections with children's daily lives and previous activities conducted in their classrooms. Teachers also identified that critical action research through group communication provided practical and useful knowledge of their educational practices. Teachers' improved pedagogical knowledge and awareness about EE increased their confidence to teach environmental education. To lessen the burden of going on a field trip to environments, teachers provided children direct experiences in the environment surrounding schools and during school picnics. Teachers also actively participated in environmental activities with children. These direct experiences of the environment helped teachers and children appreciate the beauty of the environment and change their reluctant attitudes towards the environment. By providing parents children's products produced during EE, teachers were also able to help parents develop an interest in environmental education. While most educational research in Korean kindergartens is conducted by university-based researchers, this research inquiry revealed that action research by the effective partnership with a university-based researcher can encourage the confidence and passion of Korean kindergarten teachers to reflect and resolve issues arising from their experiences and to change educational practices.

In this paper we hypothesize that individuals will choose among alternative courses of action for power generation from wind farms according to their personality profiles. Through a factor analysis we found that certain characteristics of personality do indeed have an effect on environmental choice. The study involves an extensive survey based on the Big Five Traits model to find a pattern of choice that will help to better understand environmental decisions and be useful for policy makers to identify target groups and preview reactions to different courses of action. The research is potentially useful for the better preparation and design of publicity material, awareness raising campaigns and information provision for complex or unpopular policies affecting the environment or in environmental education in general. This research is especially interested in shedding some light on how personality is involved in the processes of environmental decision making, despite the limitations of the present study.

With the rapid development of the waste incineration industry in China, top priority has been given to the problem of pollution caused by waste incineration. This study is the first attempt to assess all the waste incineration plants in Wuhan, the only national key city in central China, in terms of environmental impact, site selection, public health and public participation. By using a multi-criterion assessment model for economic, social, public health and environmental effects, this study indicates these incineration plants are established without much consideration of the local residents’ health and environment. A location analysis is also applied and some influences of waste incineration plants are illustrated. This study further introduces a signaling game model to prove that public participation is a necessary condition for improving the environmental impact assessment and increasing total welfare of different interest groups in China. This study finally offers some corresponding recommendations for improving the environmental impact assessments of waste incineration projects. PMID:26184242

Systematizing the production of environmental plans: an Australian example

Davis, J. Richard

1985-09-01

Environmental planning legislation in New South Wales now requires local government authorities to draw up statutory plans that take into account, among other concerns, both the biophysical and the social environmental issues within their jurisdictions. The SIRO-PLAN method of plan production provides a systematic mechanism for fulfilling this requirement. This article describes the application of the method by planning researchers over 18 months to the production of a Local Environmental Plan for a rural local government in New South Wales. The policy formulation, the purposive data collection, and the deliberate adjustment of plans in order to recognize interest group requirements were all found to be valuable features of the method, while the translation of the ultimately chosen land-use plan into the explicit regulatory controls available to the local government authority was found to require further refinement. The capacity of SIRO-PLAN to quantify the resolution of competing environmental concerns in the final plan, although of value to planning researchers, proved too arcane for traditionally trained planners.

In November 2015, the Twin Ports-based People and Places Work Group (PPWG) coordinated a special gathering to bring together researchers and scholars from diverse fields to discuss environment-human research, scholarship and collaboration opportunities. Hosted by the US Environmental Protection Agency (USEPA), the group approached and invited over 150 individuals from eight regional universities. The goals were to learn who was doing or interested in doing applied research on human-environment interactions, who might have students to engage in work, who might partner with the Lake Superior National Estuarine Research Reserve (Reserve), USEPA, University of Minnesota Duluth’s Natural Resource Research Institute (NRRI), Minnesota and Wisconsin Sea Grant Institutes (Sea Grant), and other partnering institutes and who might be interested in ecosystem services work in particular. A pre-gathering survey collected initial information about this community and the adapted, open-space design gathering allowed for even more data collection about potential new colleagues to engage in the work of understanding people and place in our region. This summary reviews some of findings and presents what may be considered the beginning of a network directory to encourage and facilitate interdisciplinary research and collaboration. This report outlines the process to identify and reach out to health, social science, and humanities scholars to participate in environmental research w

This study evaluated the effect of a 10-week fundamental motor skill programme in pre-schoolers with motor problems. Alongside the general effect of the intervention, we also explored possible gender differences and the role of the environmental context (living community, socio-economic status, and recreational space inside/outside the house). The intervention group (n=47; 20 ♂ and 27 ♀) received twenty 60-min motor skill sessions (2 per week) in addition to the regular physical education curriculum for pre-schoolers; the control group (n=46; 21 ♂ and 25 ♀) did not receive additional practice. General motor competence, and locomotor and object control subscales, were assessed before and after the intervention using the Test of Gross Motor Development 2nd edition (TGMD-2). Data regarding environmental factors were gathered through a questionnaire. A Group×Gender×Time ANOVA revealed that the intervention group benefited significantly from the intervention and scored better than the control group at the post-test for general motor competence and both sub-categories (locomotor and object control skill). Moreover, the intervention programme was found to be effective in helping 49% of the intervention group to achieve an average motor skill level, according to the TGMD-2 norms, while a further decline in motor competence was observed in the control group. Interestingly, the effect appeared to be gender-specific, since object control skill improved only in girls of the intervention group. Considering the environmental context, none of the above-mentioned factors was found to have an influence on the effectiveness of the intervention. The present study highlights the need for an early motor skill programme with a gender-specific approach in order to help low skilled boys and girls master a diverse set of motor skills.

Marine alveolates (MALVs) are diverse and widespread early-branching dinoflagellates, but most knowledge of the group comes from a few cultured species that are generally not abundant in natural samples, or from diversity analyses of PCR-based environmental SSU rRNA gene sequences. To more broadly examine MALV genomes, we generated single cell genome sequences from seven individually isolated cells. Genes expected of heterotrophic eukaryotes were found, with interesting exceptions like presence of proteorhodopsin and vacuolar H + -pyrophosphatase. Phylogenetic analysis of concatenated SSU and LSU rRNA gene sequences provided strong support for the paraphyly of MALV lineages. Dinoflagellate viral nucleoproteins were found only in MALV groups that branched as sister to dinokaryotes. Our findings indicate that multiple independent origins of several characteristics early in dinoflagellate evolution, such as a parasitic life style, underlie the environmental diversity of MALVs, and suggest they have more varied trophic modes than previously thought.

Since the 1960's, an increase in the public's environmental ethics, federal species preservation, water quality protection, and interest in free flowing rivers have evolved to the current concern for stewardship and conservation of natural resources. This heightened environmental awareness creates an appetite for data, models, information management, and systematic analysis of multiple scientific disciplines. A good example of this information and analysis need resides in the Green and Yampa Rivers, tributary to the Upper Colorado River. These rivers are home to endangered native fish species including the pikeminnow and razorback sucker. Two dams, Fontenelle and Flaming Gorge, impound the Green River headwaters. The respective reservoirs store water supplies as well as generate hydropower. Conversely, the Yampa River is considered unregulated and encompasses most of Dinosaur National Monument. Recreation is highly regarded on both rivers including fishing, whitewater rafting, and aesthetic values. Vast areas of irrigated agriculture, forestry, and mineral extraction also surround these rivers. To address this information need, we developed a prototype Environmental Resources Analysis System (ERAS) spreadsheet-based decision support system (DSS). ERAS provides access to historic data sets, scientific information, statistical analysis, model outputs, and comparative methods all in a familiar and user-friendly format. This research project demonstrates a simplified decision support system for use by a diverse mix of resource managers, special interest groups, and individuals concerned about the sustainability of the Green and Yampa River ecosystem.

Archiving biological and environmental samples for retrospective analysis is a major component of systematic environmental monitoring. The long-term storage of carefully selected, representative samples in an environmental specimen bank is an important complement to the real-time monitoring of the environment. These archived samples permit:The use of subsequently developed innovative analytical technology that was not available at the time the samples were archived, for clear state-of-art identification an~ quantification of analytes of interest,The identification and quantification of analytes that are of subsequent interest but that were not of interest at the time the samples were archived, andThe comparison of present and past analytical techniques and values, providing continued credibility of past analytical values, and allowing flexibility in environmental monitoring programs.Seabirds, including albatrosses, pelicans, cormorants, terns, kittiwakes, murres, guillemots, and puffins spend most of their lives at sea and have special adaptations for feeding in the marine environment, including the ability to excrete the excess salt obtained from ingesting seawater. Many species nest in dense groups (colonies) on steep, precipitous sea-cliffs and headlands.Seabirds are long-lived and slow to mature. They occupy high positions in the marine food web and are considered sensitive indicators for the marine environment (prey includes krill, small fish, and squid). Breeding success, timing of nesting, diets, and survival rates may provide early indications of changing environmental conditions (e.g., see Hatch et aI., 1993). Chemical analysis of seabird tissues, including egg contents, can be particularly useful in determining whether contaminants (and potential biological effects) associated with human industrial activities, such as offshore petroleum and mineral exploration and development, are accumulating in marine environments. The collection and archival of seabird tissues over a period of several years will be a resource for future analyses, providing samples that can be used to determine historical baseline contaminant levels.

The realistic dilemma of environmental interest subject of legal responsibility—Based on the perspective of law and economics

As the important environmental interests subject, enterprises, public and government should assume the corresponding responsibility of pollution control and environmental protection. However, in the aspect of environment, there are failure existing in performing government responsibility, the financial expense and investment our government has participated in the aspects of pollution control and environmental protection are serious insufficient. In the meantime, in spite of the clear definition of the range and principles of enterprises’ environmental responsibility according to some corresponding law documents, in view of our country’s condition, enterprises always fail to assume their own environmental responsibility, and there are cases existing in pollution control and environmental protection that the investment is insufficient and the treatment effect is not obvious. In addition, it is especially outstanding in our country that the awareness of public environmental rights is pretty weak. The issues of ecological damage and environmental pollution get worse and worse and the total environmental interests get injured seriously because of the failure and vacancy of environmental responsibility of different subjects of right.

Game theory and environmental disputes

The courts have provided the traditional battleground for conflicts between environmental interest groups and those whose actions in some way have an adverse impact on the environment The judicial process is a time-consuming one in which all sides usually must concede to some points. Environmental disputes involve complex scientific issues which the court system is not set up to comprehend, so that the process gives the parties to a dispute the sense of having lost control of their own destinies. An increasing number of parties to environmental disputes are turning to negotiation, or mediation, as an alternative in which they can be active parties in the settlement-making process rather than the victims of a court-imposed solution When do the parties to a dispute choose a negotiated settlement over a court battle? To what extent does each party make the concessions necessary to reach an agreement? These questions can be answered by the game theory that provides a model for analyzing the negotiation process. This paper will apply game theory to two environmental conflict cases A series of questions pertinent to the analysis of all environmental disputes will be raised

The class Kinetoplastea encompasses both free-living and parasitic species from a wide range of hosts. Several representatives of this group are responsible for severe human diseases and for economic losses in agriculture and livestock. While this group encompasses over 30 genera, most of the available information has been derived from the vertebrate pathogenic genera Leishmaniaand Trypanosoma. Recent studies of the previously neglected groups of Kinetoplastea indicated that the actual diversity is much higher than previously thought. This article discusses the known segment of kinetoplastid diversity and how gene-directed Sanger sequencing and next-generation sequencing methods can help to deepen our knowledge of these interesting protists.

A considerable proportion of European adults report little or no interest in physical activity. Identifying individual-level and environmental-level characteristics of these individuals can help designing effective interventions and policies to promote physical activity. This cross-sectional study additionally explored associations between level of interest and physical activity, after controlling for other individual and environmental variables. Measures of objective and perceived features of the physical environment of residence, self-reported physical activity and other lifestyle behaviors, barriers towards physical activity, general health, and demographics were obtained from 5205 European adults participating in the 2014 online SPOTLIGHT survey. t-Tests, chi-square tests, and generalized estimating equations with negative binomial log-link function were conducted. Adults not interested in physical activity reported a higher BMI and a lower self-rated health, were less educated, and to a smaller extent female and less frequently employed. They were more prone to have less healthy eating habits, and to perceive more barriers towards physical activity. Only minor differences were observed in environmental attributes: the non-interested were slightly more likely to live in neighborhoods objectively characterized as less aesthetic and containing more destinations, and perceived as less functional, safe, and aesthetic. Even after controlling for other individual and environmental factors, interest in physical activity remained a significant correlate of physical activity, supporting the importance of this association. This study is among the first to describe characteristics of individuals with reduced interest in physical activity, suggesting that (lack of) interest is a robust correlate of physical activity in several personal and environmental conditions.

Paper-based supercapacitors (SCs), a novel and interesting group of flexible energy storage devices, are attracting more and more attention from both industry and academia. Cellulose papers with a unique porous bulk structure and rough and absorptive surface properties enable the construction of paper-based SCs with a reasonably good performance at a low price. The inexpensive and environmentally friendly nature of paper as well as simple fabrication techniques make paper-based SCs promising candidates for the future 'green' and 'once-use-and-throw-away' electronics. This review introduces the design, fabrication and applications of paper-based SCs, giving a comprehensive coverage of this interesting field. Challenges and future perspectives are also discussed.

Social amplification of risk in the Internet environment.

PubMed

Chung, Ik Jae

2011-12-01

This article analyzes the dynamic process of risk amplification in the Internet environment with special emphasis on public concern for environmental risks from a high-speed railway tunnel construction project in South Korea. Environmental organizations and activists serving as social stations collected information about the project and its ecological impact, and communicated this with the general public, social groups, and institutions. The Internet provides social stations and the public with an efficient means for interactive communication and an open space for active information sharing and public participation. For example, while the website of an organization such as an environmental activist group can initially trigger local interest, the Internet allows this information to be disseminated to a much wider audience in a manner unavailable to the traditional media. Interaction among social stations demonstrates an amplifying process of public attention to the risk. Analyses of the volume of readers' comments to online newspaper articles and public opinions posted on message board of public and nonprofit organizations show the ripple effects of the amplification process as measured along temporal, geographical, and sectoral dimensions. Public attention is also influenced by the symbolic connotations of risk information. Interpretations of risk in religious, political, or legal terms intensify public concern for the environmental risk. © 2011 Society for Risk Analysis.

The Contribution of Environmental Studies Curricula to Environmental Decision Making

NASA Astrophysics Data System (ADS)

Lord, Jean

Current studies indicate that college environmental-science curriculums are often inadequate and not meaningful to college students. Yet climate change, depletion of natural resources, and loss of habitat due to human activities are among critical environmental issues. It is important that college students are prepared to address these issues after graduation. This case study attempted to discover the ways that college students perceived how participation in environmental science courses contributed to their environmental decision making and ecological intelligence. The population consisted of 15 sophomore, junior, and senior students randomly selected from a list of science students provided by the registrar. The conceptual framework that guided this study includes 5 components of ecological intelligence: biodiversity, ecological literacy, decision making skills, understanding sustainability, and systems thinking. The data collected over a period of 3 months from focus groups, individual interviews, and student discussions were transcribed and coded using typological analysis to identify students' perspectives on environmental science courses. Findings showed that college science curriculums need to incorporate students' prior environmental experiences into science courses. They should also focus on providing hands on experiences that promote application of knowledge to address environmental problems. This study may promote the implementation of integrated college science curriculums that encourage environmental, interdisciplinary, and personalized learning experiences. Implications for positive social change include college environmental studies and curricula that motivate students and engage their interest in participating in environmental activities.

Ecosystem extent and fragmentation

One of the candidate essential biodiversity variable (EBV) groups described in the seminal paper by Pereira et al. (2014) concerns Ecosystem Structure. This EBV group is distinguished from another EBV group which encompasses aspects of Ecosystem Function. While the Ecosystem Function EBV treats ecosystem processes like nutrient cycling, primary production, trophic interactions, etc., the Ecosystem Structure EBV relates to the set of biophysical properties of ecosystems that create biophysical environmental context, confer biophysical structure, and occur geographically. The Ecosystem Extent and Fragmentation EBV is one of the EBVs in the Ecosystem Structure EBV group.Ecosystems are understood to exist at multiple scales, from very large areas (macro-ecosystems) like the Arctic tundra, for example, to something as small as a tree in an Amazonian rain forest. As such, ecosystems occupy space and therefore can be mapped across any geography of interest, whether that area of interest be a site, a nation, a region, a continent, or the planet. One of the most obvious and seemingly straightforward EBVs is Ecosystem Extent and Fragmentation. Ecosystem extent refers to the location and geographic distribution of ecosystems across landscapes or in the oceans, while ecosystem fragmentation refers to the spatial pattern and connectivity of ecosystem occurrences on the landscape.

Since 1990, the EC-US Task Force on Biotechnology Research has been coordinating transatlantic efforts to guide and exploit the ongoing revolution in biotechnology and the life sciences. The Task Force was established in June 1990 by the European Commission and the White House Office of Science and Technology Policy. The Task Force has acted as an effective forum for discussion, coordination, and development of new ideas for the last 18 years. Task Force members are European Commission and US Government science and technology administrators who meet annually to enhance communication across the Atlantic, and to encourage collaborative research. Through sponsoringmore » workshops, and other activities, the Task Force also brings together scientific leaders and early career researchers from both sides of the Atlantic to forecast research challenges and opportunities and to promote better links between researchers. Over the years, by keeping a focus on the future of science, the Task Force has played a key role in establishing a diverse range of emerging scientific fields, including biodiversity research, neuroinformatics, genomics, nanobiotechnology, neonatal immunology, transkingdom molecular biology, biologically-based fuels, and environmental biotechnology. The EC-US Task Force has sponsored a number of Working Groups on topics of mutual transatlantic interest. The idea to create a Working Group on Environmental Biotechnology research was discussed in the Task Force meeting of October 1993. The EC-US Working Group on Environmental Biotechnology set as its mission 'To train the next generation of leaders in environmental biotechnology in the United States and the European Union to work collaboratively across the Atlantic.' Since 1995, the Working Group supported three kinds of activities, all of which focus one early career scientists: (1) Workshops on the use of molecular methods and genomics in environmental biotechnology; (2) Short courses with theoretical, laboratory and field elements; and (3) Short term exchange fellowships. The short term exchange fellowships were created to enable young scientists to develop collaborations with colleagues across the Atlantic and to learn a new skill or expertise in the area of environmental biotechnology.« less

Effect of Environmental Enrichment on Singly- and Group-Housed Squirrel Monkeys

NASA Technical Reports Server (NTRS)

Spring, Sarah E.; Clifford, James O.; Tomko, David L.; Hargens, Alan R. (Technical Monitor)

1996-01-01

Nonhuman primates display an interest in novel places, habituate to new situations, and spend most of their daily activity in the wild in large groups engaging in feeding behaviors. Captivity changes these behaviors, and disrupts normal social hierarchies. In captivity, animals may exhibit stereotypical behaviors which are thought to indicate decreased psychological well-being (PWB). If an animal's behaviors can be made to approach those seen in the wild, and stereotypical behaviors are minimal it is assumed that PWB is adequate. Environmental enrichment (EE) devices have been used to address the Animal Welfare Act's requirement that the PWB of captive nonhuman primates be considered. The purpose of the present study was to examine whether various EE devices improve the PWB of captive squirrel monkeys. The present study used behavioral observation to quantify the effectiveness of several EE devices in reducing stereotypical behaviors in squirrel monkeys housed singly or in groups. Results showed that the EE devices used did not affect the expression of normal or stereotypical behaviors, but that the type of housing did.

The Cooperative Monitoring Center (CMC) promotes collaborations among scientists and researchers in several regions as a means of achieving common regional security objectives. To promote cooperation in South Asia on environmental research, an international working group made up of participants from Bangladesh, India, Nepal, Pakistan, and the United States convened in Kathmandu, Nepal, from February 17-23,2002. The workshop was held to further develop the South Asia Transboundary Water Quality Monitoring (SATWQM) project. The project is sponsored in part by the CMC located at Sandia National Laboratories in Albuquerque, New Mexico through funding provided by the US. Department of State, Regionalmore » Environmental Affairs Office, American Embassy, Kathmandu, Nepal, and the National Nuclear Security Administration's (NNSA) Office of Nonproliferation and National Security. This report summarizes the SATWQM project, the workshop objectives, process and results. The long-term interests of the participants are to develop systems for sharing regional environmental information as a means of building confidence and improving relations among South Asian countries. The more immediate interests of the group are focused on activities that foster regional sharing of water quality data in the Ganges and Indus River basins. Issues of concern to the SATWQM network participants include studying the impacts from untreated sewage and industrial effluents, agricultural run-off, salinity increases in fresh waters, the siltation and shifting of river channels, and the environmental degradation of critical habitats such as wetlands, protected forests, and endangered aquatic species conservation areas. The workshop focused on five objectives: (1) a deepened understanding of the partner organizations involved; (2) garnering the support of additional regional and national government and non-government organizations in South Asia involved in river water quality monitoring; (3) identification of sites within the region at which water quality data are to be collected; (4) instituting a data and information collection and sharing process; and, (5) training of partners in the use of water quality monitoring equipment.« less

Selecting species for marine assessment of radionuclides around Amchitka: planning for diverse goals and interests.

PubMed

Burger, Joanna; Gochfeld, Michael; Jewett, Stephen

2006-12-01

Considerable attention has been devoted to selecting bioindicator species as part of monitoring programs for exposure and effects from contaminants in the environment. Yet the rationale for selection of bioindicators is often literature-based, rather than developed with a firm site-specific base of data on contaminant levels in a diverse range of organisms at different trophic levels in the same ecosystem. We suggest that this latter step is an important phase in the environmental assessment process that is often missing. In this paper we address the problem of how to select a wide range of species representing different trophic levels that serve as a basis for selecting a few species suitable as bioindicators. We illustrate this with our assessment of radionuclides on Amchitka Island, Alaska. We propose a multi-stage process for arriving at the list of available species that includes review of literature, review by experts experienced in the area, review by interested and affected parties, selection of trophic levels or groups for analysis, arraying of possible species, and selection of species within each trophic level group for sample collection. We first had to identify all likely species, then narrow our focus to those we could collect and analyze. In all cases, review includes suggestions for possible target species with justifications. While this method increases the up-front costs of developing bioindicators for an ecosystem, it has the advantage of providing information for selection of species that will be most informative in the long run, including those that are the best bioaccumulators, thus providing the earliest warning of any potential environmental consequences. Further, the recognition that a range of stakeholder's needs and interests should be included increases the utility for public-policy makers, and the potential for continued usage to establish long-term trends.

Environmental democracy in action: The Toxics Release Inventory

NASA Astrophysics Data System (ADS)

Lynn, Frances M.; Kartez, Jack D.

1994-07-01

The Toxics Release Inventory (TRI) created by the 1986 Emergency Planning and Community Right-to-Know Act initially received limited attention. During the early years of its implementation, the TRI has become the basis for a national experiment in voluntaristic problem solving among citizens and industry, but that process of environmental democracy hinges on citizens' ability to actually acquire, understand, and apply the new data on industrial toxic emissions. A national study of TRI-using organizations in the public and private sectors reveals that effective citizen access depends in part on the efforts of intermediary public interest groups to bridge individual needs and right-to-know data. Although the TRI has had early success as a supplement to conventional command and control regulation, questions exist about the extent to which state and federal government should or must provide special efforts to make environmental information access work for citizens.

Pollution by metal and metalloid ions is one of the most widespread environmental concerns. They are non-biodegradable, and, generally, present high water solubility facilitating their environmental mobilisation interacting with abiotic and biotic components such as adsorption onto natural colloids or even accumulation by living organisms, thus, threatening human health and ecosystems. Therefore, there is a high demand for effective removal treatments of heavy metals, making the application of adsorption materials such as polymer-functionalized nanocomposites (PFNCs), increasingly attractive. PFNCs retain the inherent remarkable surface properties of nanoparticles, while the polymeric support materials provide high stability and processability. These nanoparticle-matrix materials are of great interest for metals and metalloids removal thanks to the functional groups of the polymeric matrixes that provide specific bindings to target pollutants. This review discusses PFNCs synthesis, characterization and performance in adsorption processes as well as the potential environmental risks and perspectives. Copyright © 2016 Elsevier Ltd.

Effect of an environmental science curriculum on students' leisure time activities

NASA Astrophysics Data System (ADS)

Blum, Abraham

Cooley and Reed's active interest measurement approach was combined with Guttman's Facet Design to construct a systematic instrument for the assessment of the impact of an environmental science course on students' behavior outside school. A quasimatched design of teacher allocation to the experimental and control groups according to their preferred teaching style was used. A kind of dummy control curriculum was devised to enable valid comparative evaluation of a new course which differs from the traditional one in both content and goal. This made it possible to control most of the differing factors inherent in the old and new curriculum. The research instrument was given to 1000 students who were taught by 28 teachers. Students who learned according to the experimental curriculum increased their leisure time activities related to the environmental science curriculum significantly. There were no significant differences between boys and girls and between students with different achievement levels.

2012-01-01

Approximately 13% of all births occur prior to 37 weeks gestation in the U.S. Some established risk factors exist for preterm birth, but the etiology remains largely unknown. Recent studies have suggested an association with environmental exposures. We examined the relationship between preterm birth and exposure to a commonly used herbicide, atrazine, in drinking water. We reviewed Kentucky birth certificate data for 2004-2006 to collect duration of pregnancy and other individual-level covariates. We assessed existing data sources for atrazine levels in public drinking water for the years 2000-2008, classifying maternal county of residence into three atrazine exposure groups. We used logistic regression to analyze the relationship between atrazine exposure and preterm birth, controlling for maternal age, race/ethnicity, education, smoking, and prenatal care. An increase in the odds of preterm birth was found for women residing in the counties included in the highest atrazine exposure group compared with women residing in counties in the lowest exposure group, while controlling for covariates. Analyses using the three exposure assessment approaches produced odds ratios ranging from 1.20 (95% confidence interval [CI] 1.14, 1.27) to 1.26 (95% CI 1.19, 1.32), for the highest compared with the lowest exposure group. Suboptimal characterization of environmental exposure and variables of interest limited the analytical options of this study. Still, our findings suggest a positive association between atrazine and preterm birth, and illustrate the need for an improved assessment of environmental exposures to accurately address this important public health issue.

A Mentoring Program in Environmental Science for Underrepresented Groups

NASA Astrophysics Data System (ADS)

Stevens, L.; Rizzo, D. M.

2009-12-01

We developed a four-year program, combining educational and career support and research activities, to recruit and retain students from underrepresented groups in environmental sciences. Specifically, the program: ○ Assigns each student a faculty or graduate student mentor with whom the student conducts research activities. ○ Includes a weekly group meeting for team building and to review professional development and academic topics, such as time management and research ethics. ○ Requires students to make multiple formal presentations of their research proposals and results. ○ Provides scholarships and stipends for both the academic year and to engage students in summer research. The program seeks to achieve several goals including: ● Enhance academic performance. ● Encourage continued study in environmental science. ● Facilitate students completing their studies at UVM. ● Increase students’ interest in pursuing science careers. ● Create a more welcoming academic environment. To assess progress toward achievement of these goals, we conducted individual structured interviews with participating undergraduate students, graduate students, and faculty members at two points in time. First, interviews were conducted in the fall of 2007 after two years, and again in spring 2009, after four years. An independent research consultant, Dr. Livingston, conducted the interviews. In 2009, over the course of three days, the interviews included three graduate student and two faculty mentors, and six of the seven undergraduate students. Of the six students, three were juniors and three were graduating seniors. Results of the 2009 interviews echoed those of 2007. Both students and their mentors are quite satisfied with the program. The student presentations, weekly meetings, mentoring relationships, and summer research experiences all get high ratings from program participants. Students give high praise to their mentors and the program directors for providing excellent support. Looking at goals more specifically, we find: Improved student academic performance: Most students credit the program with a positive impact on their academic performance. Students’ continued study of environmental science: Students report increased or continued interest in environmental science as a result of participating in the program. Continued study at UVM: In both 2007 and 2009 there was a nearly unanimous report that students remain at UVM because of their involvement in the program. The program provides valuable opportunities, advisory support, community of peers, and financial stipend. It is has attracted and kept these students at this university. Increased interest in science careers: Students have been exposed to a range of science careers and credit the program with providing this exposure. Most of these students expect to pursue a career in science. Created a welcoming environment: One student specifically credits the program with increasing the number of students of color in the department. Other students credit the program with creating an environment in which students have established relationships with many faculty, certainly contributing to a welcoming atmosphere. Taken together, results indicate that the program is indeed achieving its goals.

The phenotypic (observed), genetic, and environmental correlations were examined in a sample of adult twins between the four factors and global score of the trait emotional intelligence questionnaire (TEIQue) and the seven vocational interest factors of the Jackson Career Explorer (JCE). Multiple significant correlations were found involving the work style vocational interest factor (consisting of job security, stamina, accountability, planfulness, and interpersonal confidence) and the social vocational interest factor (which included interests in the social sciences, personal services, teaching, social services, and elementary education), both of which correlated significantly with all of the TEIQue variables (well-being, self-control, emotionality, sociability, and global trait EI). Following bivariate genetic analyses, most of the significant phenotypic correlations were found to also have significant genetic correlations as well as significant non-shared (unique) environmental correlations.

Technology assessment or technology harassment: The attacks on science and technology

NASA Technical Reports Server (NTRS)

Green, L., Jr.

1972-01-01

The manner in which technology is being assessed by various groups and individuals is discussed. Attacks on science and technology (specifically military uses and funding), and the disillusionment of the public with the lack of relevance of science to the public interest and with the infallible wisdom of scientists are described. The effects of the fear of environmental pollution are emphasized. It is concluded that the important issues of science, technology, and public policy will require a pluralistic definition of the public interest by open adversary proceedings. It is also felt that the danger is not that new technology will receive inadequate assessment for possible deleterious secondary effects, but that harassment by an overemotional political process may prevent its coming to fruition.

From Data Refuge to the Libraries+ Network: New Partnerships and Ideas for Ensuring Continued Access to Federal Data

NASA Astrophysics Data System (ADS)

Janz, M.

2017-12-01

Data Refuge began as concerns grew about the vulnerability of federal climate and environmental data. The project began by hosting a Data Rescue event that intended to educate attendees about the risks that exist for digital information, advocate for the many local uses of climate and environmental data, and create research copies of federal climate and environmental data that would be held off federal servers. This workflow was used by many other Data Rescue events over the next few months and caught the attention of many interested groups. Those groups included federal agencies, data managers and curators, open data and open government proponents, and librarians and archivists. The Data Refuge project team brought these stakeholders together at the Libraries+ Network meeting to talk about this complicated problem space and to encourage new partnerships to experiment with solutions. The team at University of Pennsylvania is working on federal, regional, and local projects that address some aspects of the problem while many other organizations and universities are working on others. This talk will serve as an update on those projects, the lessons learned from them, and the challenges that remain.

Providing Consumers with Web-Based Information on the Environmental Effects of Automobiles

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

Saulsbury, J.W.

The Department of Energy (DOE) and the Environmental Protection Agency (EPA) provide consumers with web-based information on the environmental effects of automobiles so that individuals can make informed choices about the vehicles they use or may purchase. DOE and EPA maintain a web site (www.fueleconomy.gov) that provides users with information about fuel economy [as well as greenhouse gas (GHG) emissions and air pollution emissions] for the cars and trucks they use or may consider purchasing. EPA also maintains a separate web site (www.epa.gov/greenvehicles) that offers similar information, with the focus on air pollution emissions rather than fuel economy. The Americanmore » Council for an Energy-Efficient Economy (ACEEE) (www.greenercars.com) and the California Air Resources Board (CARB) (www.arb.ca.gov/msprog/ccbg/ccbg.htm) also maintain web sites that provide consumers with information on the environmental effects of automobiles. Through the National Transportation Research Center (NTRC) at Oak Ridge National Laboratory, DOE has supported some initial qualitative research with people who are interested in purchasing a new or used vehicle and whose actions identify them as at least somewhat concerned about the environment. The purpose of this research was to explore and understand how these people respond to the different ratings and measurements of environmental effects provided by the four web sites. The goal of the research is to optimize the communication of information provided on the DOE/EPA web site (www.fueleconomy.gov). Working with a private marketing research firm (The Looking Glass Group of Knoxville, Tennessee), NTRC staff initiated this research by meeting with two focus groups in Knoxville on February 27, 2001. To obtain information for comparison, staff from the NTRC and the Looking Glass Group also met with two focus groups in Los Angeles, California, on August 13, 2001.« less

On Unsaturated Soil Mechanics - Personal Views on Current Research

Pande, G. N.; Pietruszczak, S.

2015-09-01

This paper presents the authors' personal views on current research being conducted by various research groups around the world in the broad area of mechanics of unsaturated geomaterials in general and soils in particular. The topic is of interest to a wide spectrum of scientists and engineers working in diverse areas such as geology and geophysics, powder technology, agricultural, petroleum, chemical, geotechnical, civil, environmental and nuclear engineering. Even if we restrict ourselves to civil, geotechnical and environmental engineering, it is noted that a plethora of hypotheses as well as a number of empirical and semi-empirical relations have been introduced for describing the mechanics of unsaturated porous media. However, many of these proposed advances as well as methods of testing may lack sound theoretical basis.

Evidence for heritability of adult men's sexual interest in youth under age 16 from a population-based extended twin design.

PubMed

Alanko, Katarina; Salo, Benny; Mokros, Andreas; Santtila, Pekka

2013-04-01

Sexual interest in children resembles sexual gender orientation in terms of early onset and stability across the life span. Although a genetic component to sexual interest in children seems possible, no research has addressed this question to date. Prior research showing familial transmission of pedophilia remains inconclusive about shared environmental or genetic factors. Studies from the domains of sexual orientation and sexually problematic behavior among children pointed toward genetic components. Adult men's sexual interest in youthfulness-related cues may be genetically influenced. The aim of the present study was to test whether male sexual interest in children and youth under age 16 involves a heritable component. The main outcome measure was responses in a confidential survey concerning sexual interest, fantasies, or activity pertaining to children under the age of 16 years during the previous 12 months. The present study used an extended family design within behavioral genetic modeling to estimate the contributions of genetic and environmental factors in the occurrence of adult men's sexual interest in children and youth under age 16. Participants were male twins and their male siblings from a population-based Finnish cohort sample aged 21-43 years (N = 3,967). The incidence of sexual interest in children under age was 3%. Twin correlations were higher for monozygotic than for dizygotic twins. Behavioral genetic model fitting indicated that a model including genetic effects as well as nonshared environmental influences (including measurement error), but not common environmental influences, fits the data best. The amount of variance attributable to nonadditive genetic influences (heritability) was estimated at 14.6%. The present study provides the first indication that genetic influences may play a role in shaping sexual interest toward children and adolescents among adult men. Compared with the variance attributable to nonshared environmental effects (plus measurement error), the contribution of any genetic factors seems comparatively weak. Future research should address the possible interplay of genetic with environmental risk factors, such as own sexual victimization in childhood. © 2013 International Society for Sexual Medicine.

Environmental geology: Our professional public responsibility

Conflicts between different interest groups for use of natural resources is one area where state geological surveys can provide assistance. A state geological survey working within the scientific constraints of specific issues can remain objective in its presentations and maintain the faith of both the conflicting interest groups and the public. One cannot vary from the objective view or you will quickly be criticized. Criticism can still occur from one side of a natural resource issue as your data might counter their views. However, the final decisions are almost always made in some legislators, or regulators, area of responsibility. The responsibility of the state geological survey is to provide the important data that will assist in making correct decisions. Should one party in the conflict become extreme in their demands, a potential compromise that is beneficial to both sides can be lost. In Kansas, the classical natural resource problem of resource/recreation in a populated area is presented as a case study. The state geological survey presented data on sand resources in the Kansas River and its valley in northeast Kansas. That information was important to both recreation and dredging interests where the political problem is a conflict of sand use as a construction material resource versus use of the alluvial river as an important recreation area, especially for canoeing. However, when a reasonable compromise was near completion in the Kansas Legislature one side, in a bold move to develop an advantage, ruined that potential for compromise.Conflicts between different interest groups for use of natural resources is one area where state geological surveys can provide assistance.

The main objective of PINCHE is to provide policy recommendations aiming at protecting children's health and environment based on completed scientific research. The project focused on four themes: indoor and outdoor air pollutants, carcinogens, neurotoxicants, and noise. The data were evaluated in workpackages on exposure assessment, epidemiology, toxicology, and risk and health impact assessment. The data were analysed according to a framework of questions. The workpackage on socioeconomic factors studied the influence of socioeconomic status on exposures and on health effects. In the workpackage on science-policy interface, recommendations on how to improve children's environmental health were formulated. The policy recommendations resulting from the analysis were grouped according to relevant policy levels: European Commission or the European Parliament, member states and other stakeholders at regional or local level. These recommendations are general guidelines for taking action. Regional differences and variation must be reflected when policy is actually implemented. In addition, recommendations related to education and personal behaviour are presented in the reports. The policy recommendations are important input for policy advisers, policy makers and public health authorities at all policy levels. The recommendations are also of direct relevance to interest groups, such as environmental NGOs including child health and advocacy groups. The policy recommendations for each policy level were prioritized. High priorities were given to reduce exposure to environmental tobacco smoke, transport related air pollution, indoor air and mercury.

Environmental manipulation at early critical periods could have long-lasting effects. In spite of the great interest in the biological effects of the environmental condition so far, its long-lasting effects are less documented. This study looks at the enduring effects of rearing condition on tasks that measure affective responses and exploratory behavior in male Wistar rats. The animals were reared from weaning to adulthood in an enriched environment, standard laboratory condition, or isolated condition. Then, all rats were housed in standard laboratory cages to provide a common environment, and successively exposed to different tests between 0 and 11 weeks post-manipulation. The open field test indicated a more efficient exploratory behavior in the enriched group, and an enhanced spontaneous motor activity in both standard and isolated groups. In addition, rats reared in standard condition showed heightened motor activity in forced swimming test and elevated plus maze. Forced swimming test showed an antidepressive-like effect in the enriched environment group by increased climbing behavior. In respect to the anxiety behavior, environmental enrichment improved threat detection ability. It is concluded that rearing condition from weaning to adulthood has important and long-lasting effects on depressive- and anxiety-like and exploratory behaviors as well as motor activity.

Involving citizens, interest groups, and regulators in environmental restoration and waste management programs is a challenge for government agencies and the organizations that support them. To be effective, such involvement activities must identify all individuals and groups who have a stake in the cleanup. Their participation must be early, substantive, and meaningful. Stockholders must be able to see how their input was considered and used, and feel that a good- faith effort was made to reconcile conflicting objectives.

In South America, economic interests in last years have produced a constant increase in transgenic soybean cropping, with the corresponding rise in pesticide formulated products. The aim of this study was to determine the effects of pesticides formulations and mixtures on a South American caiman, Caiman latirostris, after in ovo exposure. We conducted a field-like experiment which simulates the environmental exposure that a caiman nest can receive in neighbouring croplands habitats. Experimental groups were Control group, Treatment 1: sprayed with a glyphosate herbicide formulation, and Treatment 2: sprayed with a pesticide mixture of glyphosate, endosulfan and cypermethrin formulations. Results demonstrated genotoxicity, enzymatic and metabolic alterations, as well as growth delay in caimans exposed in ovo to Treatments 1 and 2, showing a higher toxicity for the mixture. Integral evaluation through biomarkers of different biological meaning is highly informative as early indicators of contamination with pesticides and mixtures in this wildlife species.

The purpose of this project are developed the Stakeholders engagement evaluation plan which is currently developed in University of Nevada, Reno for the Emigrant mining project, located in the central Nevada, USA, and belong to the Newmont Mining Corporation, one of the gold production leader worldwide. The needs for this project is to create the open dialog between Newmont mining company and all interested parties which have social or environmental impacts from the Emigrant mine. Identification of the stakeholders list is first and one of the most difficult steps in the developing of mine social responsibility. Stakeholders' engagement evaluation plan must be based on the timing and available resources of the mining company, understanding the goals for the engagement, and on analyzes of the possible risks from engagement. In conclusion, the Stakeholders engagement evaluation plan includes: first, determinations of the stakeholders list, which must include any interested or effected by the mine projects groups, for example: state and local government representatives, people from local communities, business partners, environmental NGOs, indigenous people, and academic groups. The contacts and availability for communication is critical for Stakeholders engagement. Next, is to analyze characteristics of all these parties and determinate the level of interest and level of their influence on the project. The next step includes the Stakeholders matrix and mapping development, where all these information will be put together.After that, must be chosen the methods for stakeholders' engagement. The methods usually depends from the goals of engagement (create the dialog lines, collect the data, determinations of the local issues and concerns, or establish the negotiation process) and available resources as a time, people, budget. Is it very important here to recognize the possible risks from the engagement and establish the key massage for stakeholders. Finally, the engagement plan should be evaluated and can be implementing for the new social responsibility practice development.

Relationships between the neighborhood environment and children's physical activity have been well documented in Western countries but are less investigated in ultra-dense Asian cities. The aim of this study was to identify the environmental facilitators and barriers of physical activity behaviors among Hong Kong Chinese children using nominal group technique. Five nominal groups were conducted among 34 children aged 10-11 years from four types of neighborhoods varying in socio-economic status and walkability in Hong Kong. Environmental factors were generated by children in response to the question "What neighborhood environments do you think would increase or decrease your willingness to do physical activity?" Factors were prioritized in order of their importance to children's physical activity. Sixteen unique environmental factors, which were perceived as the most important to children's physical activity, were identified. Factors perceived as physical activity-facilitators included "Sufficient lighting", "Bridge or tunnel", "Few cars on roads", "Convenient transportation", "Subway station", "Recreation grounds", "Shopping malls with air conditioning", "Fresh air", "Interesting animals", and "Perfume shop". Factors perceived as physical activity-barriers included "People who make me feel unsafe", "Crimes nearby", "Afraid of being taken or hurt at night", "Hard to find toilet in shopping mall", "Too much noise", and "Too many people in recreation grounds". Specific physical activity-related environmental facilitators and barriers, which are unique in an ultra-dense city, were identified by Hong Kong children. These initial findings can inform future examinations of the physical activity-environment relationship among children in Hong Kong and similar Asian cities.

Sphingomonads comprise a physiologically versatile group within the Alphaproteobacteria that includes strains of interest for biotechnology, human health, and environmental nutrient cycling. In this study, we compared 26 sphingomonad genome sequences to gain insight into their ecology, metabolic versatility, and environmental adaptations. Our multilocus phylogenetic and average amino acid identity (AAI) analyses confirm that Sphingomonas, Sphingobium, Sphingopyxis, and Novosphingobium are well-resolved monophyletic groups with the exception of Sphingomonas sp. strain SKA58, which we propose belongs to the genus Sphingobium. Our pan-genomic analysis of sphingomonads reveals numerous species-specific open reading frames (ORFs) but few signatures of genus-specific cores. The organization and coding potential of the sphingomonad genomes appear to be highly variable, and plasmid-mediated gene transfer and chromosome-plasmid recombination, together with prophage- and transposon-mediated rearrangements, appear to play prominent roles in the genome evolution of this group. We find that many of the sphingomonad genomes encode numerous oxygenases and glycoside hydrolases, which are likely responsible for their ability to degrade various recalcitrant aromatic compounds and polysaccharides, respectively. Many of these enzymes are encoded on megaplasmids, suggesting that they may be readily transferred between species. We also identified enzymes putatively used for the catabolism of sulfonate and nitroaromatic compounds in many of the genomes, suggesting that plant-based compounds or chemical contaminants may be sources of nitrogen and sulfur. Many of these sphingomonads appear to be adapted to oligotrophic environments, but several contain genomic features indicative of host associations. Our work provides a basis for understanding the ecological strategies employed by sphingomonads and their role in environmental nutrient cycling. PMID:23563954

We aimed to investigate the effects of environmental noise exposure on the growth and neuropsychological development in neonatal rats. Twenty-four postnatal 7-day-old Sprague-Dawley rats were randomly assigned into control, high-noise and reduced noise groups. The rats in the high-noise group were exposed to 90 dB white noise, and those in the control group were grown under standard condition, while those in the reduced noise group were exposed to standard condition with sound-absorbing cotton. Ten, 15, and 20 days post noise exposure, both the body weight and length of the rats in high-noise group were lower than those in the control and reduced noise groups, respectively. The secretion of growth hormone was significantly decreased in the rats exposed to high noise environment, compared to those exposed to standard condition and reduced noise. More interestingly, the swimming distance was apparently increased and the swimming speed was significantly decreased in high-noise group compared with those in control and reduced noise groups. Importantly, the mRNA and protein levels of SYP in the rats hippocampus were significantly decreased in high-noise group compare with those in control and reduced noise groups. Similarly, the positive expression of SYP in the CA1 region of hippocampus was also significantly decreased in the high noise group rats. In conclusion, our results demonstrated that high noise exposure could decrease the production of growth hormone and SYP in neonatal rats, which may retard the growth of weight and length and the capability of learning and memory.

Self-interest and pro-environmental behaviour

NASA Astrophysics Data System (ADS)

Evans, Laurel; Maio, Gregory R.; Corner, Adam; Hodgetts, Carl J.; Ahmed, Sameera; Hahn, Ulrike

2013-02-01

Inspired by the principles used to market physical products, campaigns to promote pro-environmental behaviour have increasingly emphasized self-interested (for example, economic) reasons for engaging with a self-transcendent cause (that is, protecting the environment). Yet, psychological evidence about values and behaviour suggests that giving self-interested reasons, rather than self-transcending reasons, to carry out a self-transcending action should be ineffective at increasing self-transcending behaviour more generally. In other words, such a campaign may fail to cause spillover, or an increase in other, different environmental behaviours. Here we show that recycling rates are dependent on the information participants receive about a separate environmental behaviour, car-sharing (carpooling in the USA). In two experiments, we found that recycling was significantly higher than control when participants received environmental information about car-sharing, but was no different from control when they received financial information or (in experiment 2) received both financial and environmental information. Our results suggest that, congruent with value theory, positive spillover from one environmental message to another behaviour (car-sharing to recycling) may occur primarily when self-transcending reasons alone are made salient.

Children, teachers and nature: An analysis of an environmental education program

NASA Astrophysics Data System (ADS)

Cheng, Judith Chen-Hsuan

Environmental education is an important tool for providing knowledge, supporting positive attitudes toward nature, and building skills to protect and improve the environment. Because of limited funding sources and increasing environmental challenges, it is important to provide effective environmental education programs. Program evaluation is one strategy to engage stakeholders and increase program effectiveness. An evaluation of a fourth grade environmental education program, Lagoon Quest developed by Brevard Zoo, provides an unique opportunity to answer several questions about implementing an effective environmental education program. The first question is about the effectiveness of Lagoon Quest. Evaluation data are reported in a case study that provides details about the development of the evaluation questions and evaluation instruments. The pre/posttest comparison suggests that participating in Lagoon Quest effectively increases students' knowledge of Indian River Lagoon (mean increase = 5.03, p<0.05). This program is effective among students' from different socio-economic background. Moreover, teachers and parents indicate that the program positively influenced the students and are supportive of it. Lagoon Quest is now a required program in the fourth grade curriculum in Brevard County, which raises the second question: how do teachers react to a required fourth grade program? Teachers' prior experience in environmental education, science education, Lagoon Quest and their attitudes toward Lagoon Quest were examined. A teacher survey was conducted to explore teachers' attitudes, but the low response rate necessitated a process to explore non-respondents' attitudes. Follow-up focus groups at schools with few respondents suggest that teachers who had prior experience in teaching science were more likely to be highly supportive of Lagoon Quest and were more likely to use additional resources to support the program. Also, teachers' interest in Indian River Lagoon is positively associated with their attitude toward nature. The third question uses Lagoon Quest to explore how to measure children's attitudes toward nature and the long-term development of conservation ethics. A Connection to Nature Index was developed and validated with fourth-grade students. A correlation analysis was conducted, and Connection to Nature was linked to other variables to explore its predictive ability. Four major elements were in the Connection to Nature Index: enjoyment of nature, empathy for living creatures, sense of oneness and sense of responsibility. The results suggest that measuring connection to nature (beta=0.38, p<0.05) is a promising strategy to predict children's interest in participating in nature-based activities. Also, connection to nature (beta=0.30, p<0.05) can predict children's interest in performing environmental friendly practices.

Integrating mechanistic and polymorphism data to characterize human genetic susceptibility for environmental chemical risk assessment in the 21st century

Mortensen, Holly M., E-mail: mortensen.holly@epa.gov; Euling, Susan Y.

Response to environmental chemicals can vary widely among individuals and between population groups. In human health risk assessment, data on susceptibility can be utilized by deriving risk levels based on a study of a susceptible population and/or an uncertainty factor may be applied to account for the lack of information about susceptibility. Defining genetic susceptibility in response to environmental chemicals across human populations is an area of interest in the NAS' new paradigm of toxicity pathway-based risk assessment. Data from high-throughput/high content (HT/HC), including -omics (e.g., genomics, transcriptomics, proteomics, metabolomics) technologies, have been integral to the identification and characterization ofmore » drug target and disease loci, and have been successfully utilized to inform the mechanism of action for numerous environmental chemicals. Large-scale population genotyping studies may help to characterize levels of variability across human populations at identified target loci implicated in response to environmental chemicals. By combining mechanistic data for a given environmental chemical with next generation sequencing data that provides human population variation information, one can begin to characterize differential susceptibility due to genetic variability to environmental chemicals within and across genetically heterogeneous human populations. The integration of such data sources will be informative to human health risk assessment.« less

[The biomonitoring of toxic substances in biological samples of general population].

Many of the world's most developed countries have adopted biomonitoring of toxic substances in order to ascertain their levels in biological samples. These substances get into the body through different environmental exposures. Monitoring toxic substances in biological samples should allow us to ascertain their levels in vulnerable groups, assess their evolution over time, make comparisons with levels observed in other countries, identify groups at risk or with high toxic levels and promote research. The main objective of biomonitoring is to act as a policy design tool to facilitate the implementation of particular measures in various sectors: health, environmental, agricultural and livestock or food industry sectors. In Spain, information on levels of toxic substances of environmental origin is provided by specific studies on health effects from environmental sources, such as the INMA project (INfancia y Medio Ambiente [childhood and environment]). In addition, biomonitoring projects have been implemented in Catalonia and the Canary Islands, together with a national biomonitoring programme in the adult working population. However, further progress is needed to develop a system that covers the general population as well as subgroups at risk, which relies on the collaboration of the involved authorities and the participation of professionals from different sectors and citizen organisations interested in the relationship between health and the environment.

Causes analysis on the failure of government environmental responsibility—Based on the perspective of law and economics

NASA Astrophysics Data System (ADS)

Fa, L. N.

2017-11-01

As the important Environmental Interests of Subjects, government behooves to undertake the corresponding responsibility of Pollution Control and Environmental Protection. The current situations in our country, however, appear as government environmental responsibility failure. Based on the analysis of law and economics, this article reaches the conclusion through game analysis, principle-agency relationship and utility theory that the prisoners dilemma of environmental interest game between government and enterprise, and the inherent defect of the principal-agency relationship between central government and local government are the inherent causes of government environmental responsibility failure. Many officials tends to graft and corrupt to maximum their own benefit, thus leading to the government failure among environmental pollution treatment and the environmental responsibility to undertake.

Mega-sized concerns from the nano-sized world: the intersection of nano- and environmental ethics.

PubMed

Attia, Peter

2013-09-01

As rapid advances in nanotechnology are made, we must set guidelines to balance the interests of both human beneficiaries and the environment by combining nanoethics and environmental ethics. In this paper, I reject Leopoldian holism as a practical environmental ethic with which to gauge nanotechnologies because, as a nonanthropocentric ethic, it does not value the humans who will actually use the ethic. Weak anthropocentrism is suggested as a reasonable alternative to ethics without a substantial human interest, as it treats nonhuman interests as human interests. I also establish the precautionary principle as a useful situational guideline for decision makers. Finally, I examine existing and potential applications of nanotechnology, including water purification, agriculture, mining, energy, and pollutant removal, from the perspective of weak anthropocentrism using the precautionary principle.

A large number of microorganisms reside within the gastrointestinal tract, especially in the colon, and play important roles in human health and disease. The composition of the human gut microbiota is determined by intrinsic host factors and environmental factors. While investigating environmental factors to promote human health is of great interest, few studies have focused on their effect on the gut microbiota. This study aimed to investigate differences in gut microbiota composition according to lifestyle and geographical area, even in people with similar genetic background. We enrolled ten and nine elderly women in their seventies from island and inland areas, respectively. Fecal samples were obtained from individuals, and bacterial 16S ribosomal RNA genes were analyzed by next-generation sequencing to define the gut microbiota composition. We assessed their diet, which can influence the gut microbial community. We also conducted physical examination and determined the physical activity levels of the subjects. The inland subjects had a significantly higher rectal temperature, systolic blood pressure, and heart rate and a significantly lower physical activity score than the island subjects. Fecal samples from the island group showed a tendency to have greater microbial diversity than those from the inland group. Interestingly, the microbial community composition differed significantly between the two groups. Catenibacterium was enriched in subjects from the island area. Catenibacterium showed a negative correlation with rectal temperature and a positive correlation with the dietary level of animal fat. In contrast, Butyricimonas was enriched in the inland subjects. A positive correlation was found between Butyricimonas and mean arterial pressure. This study identified differences in the gut microbiota composition between elderly women from different parts of South Korea, and our findings suggest that further studies of the human gut microbiota should evaluate aspects of the living environment.

In general, Synthetic Indexes of sustainability have been applied to specific countries and regions. With some variations, the ones considered simple, such as the case of the Ecological Footprint (EF), have been applied to port areas. The same has not happened with those of a multidimensional nature (Global Synthetics) that still have a minimal and partial presence in the analysis of port sustainability. Understanding that this type of index represents an interesting and novel avenue of research applied to port systems, this contribution analyses and ranks a sample of 16 Spanish Port Authorities that group 23 ports of general interest using a Global Synthetic Index of Sustainability (developed using the four dimensions of sustainable development: economic, institutional, environmental and social).

To promote cooperation in South Asia on environmental research, an international working group comprised of participants from Bangladesh, India, Nepal, Pakistan, Sri Lanka, and the US convened at the Soaltee Hotel in Kathmandu, Nepal, September 12 to 14, 1999. The workshop was sponsored in part by the Cooperative Monitoring Center (CMC) at Sandia National Laboratories in Albuquerque, New Mexico, through funding provided by the Department of Energy (DOE) Office of Nonproliferation and National Security. The CMC promotes collaborations among scientists and researchers in regions throughout the world as a means of achieving common regional security objectives. In the long term,more » the workshop organizers and participants are interested in the significance of regional information sharing as a means to build confidence and reduce conflict. The intermediate interests of the group focus on activities that might eventually foster regional management of some aspects of water resources utilization. The immediate purpose of the workshop was to begin the implementation phase of a project to collect and share water quality information at a number of river and coastal estuary locations throughout the region. The workshop participants achieved four objectives: (1) gaining a better understanding of the partner organizations involved; (2) garnering the support of existing regional organizations promoting environmental cooperation in South Asia; (3) identifying sites within the region at which data is to be collected; and (4) instituting a data and information collection and sharing process.« less

The hypothesis has been put forward that humans and wildlife species adverse suffered adverse health effects after exposure to endocrine-disrupting chemicals. Reported adverse effects include declines in populations, increases in cancers, and reduced reproductive function. The U.S. Environmental Protection Agency sponsored a workshop in April 1995 to bring together interested parties in an effort to identify research gaps related to this hypothesis and to establish priorities for future research activities. Approximately 90 invited participants were organized into work groups developed around the principal reported health effects-carcinogenesis, reproductive toxicity, neurotoxicity, and immunotoxicity-as well as along the risk assessment paradigm-hazard identification, dose-response assessment, exposure assessment, and risk characterization. Attention focused on both ecological and human health effects. In general, group felt that the hypothesis warranted a concerted research effort to evaluate its validity and that research should focus primarily on effects on development of reproductive capability, on improved exposure assessment, and on the effects of mixtures. This report summarizes the discussions of the work groups and details the recommendations for additional research. PMID:8880000

Use of the University of Minnesota Biocatalysis/Biodegradation Database for study of microbial degradation

PubMed Central

2012-01-01

Microorganisms are ubiquitous on earth and have diverse metabolic transformative capabilities important for environmental biodegradation of chemicals that helps maintain ecosystem and human health. Microbial biodegradative metabolism is the main focus of the University of Minnesota Biocatalysis/Biodegradation Database (UM-BBD). UM-BBD data has also been used to develop a computational metabolic pathway prediction system that can be applied to chemicals for which biodegradation data is currently lacking. The UM-Pathway Prediction System (UM-PPS) relies on metabolic rules that are based on organic functional groups and predicts plausible biodegradative metabolism. The predictions are useful to environmental chemists that look for metabolic intermediates, for regulators looking for potential toxic products, for microbiologists seeking to understand microbial biodegradation, and others with a wide-range of interests.

Alarie, Jean P.; Bruttig, A.; Miller, Gordon H.; Hill, Walter; Vo-Dinh, Tuan

1999-02-01

Bacterial and other natural materials such as plants and algae have received increasing interest for bioremediation efforts. The identificatIon of materials capable of biodegrading or sequestering environmental pollutants offers an attractive alternative to chemical or physical means of remediation. A number of bacteria capable of biodegrAding organic or reducing metal pollutants have received great interest. Similarly, the use of natural plants to absorb pollutants from soil anD liquid samples is another potential approach. Our interest lies in identification of naturally occurring algae and their ability to absorb polyaromatic compounds (PAC) from groundwater sources (i.e. streams). These algae could serve as natural water filters for streams contaminated with Polyaromatic hydrocarbons. Polycyclic aromatic compounds, which comprise a complex class of condensed multi-ring benzenoid compounds, are important environmental pollutants originating from a wide variety of natural and anthropogenic sources. PACs are generally formed during incomplete combustion or pyrolysis of organic matter containing carbon and hydrogen. Because combustion of organic materials is involved in countless natural processes or human activities, PACs are omnipresent and abundant pollutants in air, soil and water. Among energy-related products, fossil fuels are the major sources of PACs. The primary sources of airborne PACs are associated with combustion, coal coking, and petroleum catalytic cracking. Coal and shale conversion also contribute to production of PACs. Production, transportation and, use of synthetic fuels and petroleum products provide emission sources for PACs. In urban environments an significant source of PACs is diesel exhaust. Food cooking and cigarette smoking activities contribute to PAC occurrence in indoor environments. Chemical analysis of PACs is of great environmental and toxicological interest because many of them have been shown to be mutagens and/or potent carcinogens in laboratory animal assays. The parent homocyclic species, which contain only carbon and hydrogen, are the familiar polyaromatic hydrocarbon (PAH) compounds. In addition to the PAH compounds, there are thousands of substituted compounds that could have various substituent groups, such as alkyl, amino, chloro, cyano, hydroxy, oxy, or thio groups. In this study we investigate anthracene and pyrene as PAH model systems. A portable fiberoptic instrument capable of real-time measurements has been developed for field screening these PAHs in surface water and natural algae systems. Our preliminary studies investigated the detection limits of anthracene and pyrene and the adsorption properties of two algae using fluorescence monitoring. An exposure study of the algae to 5 ppb anthracene was performed to investigate the ability of the algae to adsorb PAHs.

The current socio-economic, environmental and public health challenges that countries are facing clearly need common-defined strategies to inform and support our transition to a sustainable economy. Here, the technology-critical elements (which includes Ga, Ge, In, Te, Nb, Ta, Tl, the Platinum Group Elements and most of the rare-earth elements) are of great relevance in the development of emerging key technologies-including renewable energy, energy efficiency, electronics or the aerospace industry. In this context, the increasing use of technology-critical elements (TCEs) and associated environmental impacts (from mining to end-of-life waste products) is not restricted to a national level but covers most likely a global scale. Accordingly, the European COST Action TD1407: Network on Technology-Critical Elements (NOTICE)-from environmental processes to human health threats, has an overall objective for creating a network of scientists and practitioners interested in TCEs, from the evaluation of their environmental processes to understanding potential human health threats, with the aim of defining the current state of knowledge and gaps, proposing priority research lines/activities and acting as a platform for new collaborations and joint research projects. The Action is focused on three major scientific areas: (i) analytical chemistry, (ii) environmental biogeochemistry and (iii) human exposure and (eco)-toxicology.

Engaging the public in biodiversity issues

Novacek, Michael J.

2008-01-01

To engage people in biodiversity and other environmental issues, one must provide the opportunity for enhanced understanding that empowers individuals to make choices and take action based on sound science and reliable recommendations. To this end, we must acknowledge some real challenges. Recent surveys show that, despite growing public concern, environmental issues still rank below many other problems, such as terrorism, health care, the economy, and (in the U.S.) family values. Moreover, much of the recent upswing in interest in the environment is due to the marked shift in attention to global warming away from other environmental problems such as destruction of ecosystems, water pollution, overpopulation, and biodiversity loss. Such a change in public focus often comes with a tendency to decouple various environmental problems and ignore their synergistic effects. Exacerbating this problem are arguments from the media and other sources that discourage public interest in environmental topics by characterizing the science behind them as overly complex, immersed in debate and controversy, and detached from human interests. Educational programming, media, exhibitions, and other means of public outreach should build on the welcome increase in public interest in global warming by demonstrating the interplay of various environmental disruptions. In the case of biodiversity, the importance of species in providing ecosystem services, natural beauty and pleasure, and sustaining human lives is a message that requires constant attention and recrafting to impact diverse audiences.

The advent of single-use disposable syringes along with myriad similar products for the health care industry has raised interest in the impact of these devices on the environment. Interest does not stop at impact of the device, but also includes associated pharmaceutical agents. Across the spectrum of health care, providers as well as end users of products are assessing the impact of product design and contents upon land, air, and water. In this issue of Journal of Diabetes Science and Technology, Pfützner and colleagues tackle the issue by focusing on a product for the diabetes patient. As environmental sustainability has become part of the evaluation process of many products, their assessment sheds some interesting light on the impact of a group of devices when compared and contrasted against the ever-popular disposable coffee cup or beer/soda aluminum can. Regional variations in waste disposal practices need to be understood when conducting these types of assessments. PMID:21880225

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

NASA Astrophysics Data System (ADS)

Charmatz, Kim

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

Background Relationships between the neighborhood environment and children’s physical activity have been well documented in Western countries but are less investigated in ultra-dense Asian cities. The aim of this study was to identify the environmental facilitators and barriers of physical activity behaviors among Hong Kong Chinese children using nominal group technique. Methods Five nominal groups were conducted among 34 children aged 10–11 years from four types of neighborhoods varying in socio-economic status and walkability in Hong Kong. Environmental factors were generated by children in response to the question “What neighborhood environments do you think would increase or decrease your willingness to do physical activity?” Factors were prioritized in order of their importance to children’s physical activity. Results Sixteen unique environmental factors, which were perceived as the most important to children’s physical activity, were identified. Factors perceived as physical activity-facilitators included “Sufficient lighting”, “Bridge or tunnel”, “Few cars on roads”, “Convenient transportation”, “Subway station”, “Recreation grounds”, “Shopping malls with air conditioning”, “Fresh air”, “Interesting animals”, and “Perfume shop”. Factors perceived as physical activity-barriers included “People who make me feel unsafe”, “Crimes nearby”, “Afraid of being taken or hurt at night”, “Hard to find toilet in shopping mall”, “Too much noise”, and “Too many people in recreation grounds”. Conclusions Specific physical activity-related environmental facilitators and barriers, which are unique in an ultra-dense city, were identified by Hong Kong children. These initial findings can inform future examinations of the physical activity-environment relationship among children in Hong Kong and similar Asian cities. PMID:25187960

We compared the effectiveness of environmental variables, and in particular of land-use indicators, to explain species richness patterns across taxonomic groups and biogeographical scales (i.e. overall pan-Europe and ecoregions within pan-Europe). Using boosted regression trees that handle non-linear relationships, we compared the relative influence (as a measure of effectiveness) of environmental variables related to climate, landscape (or habitat heterogeneity), land-use intensity or energy availability to explain European vertebrate species richness (birds, amphibians, and mammals) at the continental and ecoregion scales. We found that dominant land cover and actual evapotranspiration that relate to energy availability were the main correlates of vertebrate species richness over Europe. At the ecoregion scale, we identified four distinct groups of ecoregions where species richness was essentially associated to (i) seasonality of temperature, (ii) actual evapotranspiration and/or mean annual temperature, (iii) seasonality of precipitation, actual evapotranspiration and land cover) and (iv) and an even combination of the environmental variables. This typology of ecoregions remained valid for total vertebrate richness and the three vertebrate groups taken separately. Despite the overwhelming influence of land cover and actual evapotranspiration to explain vertebrate species richness patterns at European scale, the ranking of the main correlates of species richness varied between regions. Interestingly, landscape and land-use indicators did not stand out at the continental scale but their influence greatly increased in southern ecoregions, revealing the long-lasting human footprint on land-use–land-cover changes. Our study provides one of the first multi-scale descriptions of the variability in the ranking of correlates across several taxa. PMID:26161981

2015-02-01

This study differentiated groups of Ohio tree farmers through multivariate clustering of their perceived needs for forest management outreach. Tree farmers were surveyed via a mailed questionnaire. Respondents were asked to rate, on a 1-7 scale, their informational needs for 26 outreach topics, which were reduced to six factors. Based on these factors, three clusters were identified—holistic managers, environmental stewards, and pragmatic tree farmers. Cluster assignment of individuals was dependent upon a tree farmer's age, acreage owned, and number of years enrolled in the American Tree Farm System. Holistic managers showed a greater interest in the outreach topics while pragmatic tree farmers displayed an overall lesser interest. Across clusters, print media and in-person workshops were preferred over emails and webinars for receiving forest management information. In-person workshops should be no more than 1 day events, held on a weekday, during the daytime, at a cost not exceeding 35. Programming related to environmental influences, which included managing for forest insects and diseases, was concluded to have the greater potential to impact clientele among all outreach factors due to the information being applicable across demographics and/or management objectives.

The dual role of microbes in corrosion

PubMed Central

Kip, Nardy; van Veen, Johannes A

2015-01-01

Corrosion is the result of a series of chemical, physical and (micro) biological processes leading to the deterioration of materials such as steel and stone. It is a world-wide problem with great societal and economic consequences. Current corrosion control strategies based on chemically produced products are under increasing pressure of stringent environmental regulations. Furthermore, they are rather inefficient. Therefore, there is an urgent need for environmentally friendly and sustainable corrosion control strategies. The mechanisms of microbially influenced corrosion and microbially influenced corrosion inhibition are not completely understood, because they cannot be linked to a single biochemical reaction or specific microbial species or groups. Corrosion is influenced by the complex processes of different microorganisms performing different electrochemical reactions and secreting proteins and metabolites that can have secondary effects. Information on the identity and role of microbial communities that are related to corrosion and corrosion inhibition in different materials and in different environments is scarce. As some microorganisms are able to both cause and inhibit corrosion, we pay particular interest to their potential role as corrosion-controlling agents. We show interesting interfaces in which scientists from different disciplines such as microbiology, engineering and art conservation can collaborate to find solutions to the problems caused by corrosion.

Gray, Robert H.; Becker, C. Dale

1993-07-01

Numerous challenges face those involved with developing a coordinated and consistent approach to cleaning up the US Department of Energy’s (DOE) Hanford Site in southeastern Washington. These challenges are much greater than those encountered when the site was selected and the world’s first nuclear complex was developed almost 50 years ago. This article reviews Hanford’s history, operations, waste storage/disposal activities, environmental monitoring, and today’s approach to characterize and clean up Hanford under a Federal Facility Agreement and Consent Order, signed by DOE, the Environmental Protection Agency, and the Washington Sate Department of Ecology. Although cleanup of defense-related waste at Hanford holds many positive benefits, negative features include high costs to the US taxpayer, numerous uncertainties concerning the technologies to be employed and the risks involved, and the high probability that special interest groups and activists at large will never be completely satisfied. Issues concerning future use of the site, whether to protect and preserve its natural features or open it to public exploitation, remain to be resolved.

Osma, Johann F.; Toca-Herrera, José L.; Rodríguez-Couto, Susana

2010-01-01

Laccases are an interesting group of multi copper enzymes, which have received much attention of researchers in the last decades due to their ability to oxidise both phenolic and nonphenolic lignin-related compounds as well as highly recalcitrant environmental pollutants. This makes these biocatalysts very useful for their application in several biotechnological processes, including the food industry. Thus, laccases hold great potential as food additives in food and beverage processing. Being energy-saving and biodegradable, laccase-based biocatalysts fit well with the development of highly efficient, sustainable, and eco-friendly industries. PMID:21048873

The environmental performance of SMEs in the Brazilian textile industry and the relationship with their financial performance.

Lucato, Wagner Cezar; Costa, Elpidio Moreira; de Oliveira Neto, Geraldo Cardoso

2017-12-01

Currently, the concern with the environment is increasing and organizations seek solutions to preserve nature and at the same time earn higher profits or competitiveness. For this, they make frequent use of structured procedures in order to reduce their costs and expenses. However, it has not been always considered the environmental performance related to the financial performance of these processes. Therefore, this study aimed to investigate the relationship between environmental performance measured by eco-efficiency level with the financial performance of small and medium textile manufacturing companies. This study was done through a survey conducted in the interest of research companies in the state of Paraná in Brazil, where financial and environmental performance indicators were measured. The data analysis and validation of the hypotheses proposed, to some extent showed a surprising result because the larger the size of the company, the worst its environmental performance measured by their eco-efficiency level. On the other hand, it was not possible to identify a statistically significant relationship between environmental and financial performances of the companies surveyed. Therefore, it is concluded that this study is in line with those authors who claim not to be possible to establish a direct relationship between environmental and financial performances of companies, in opposition of another group of authors who claim contrariwise.

Teaching Environmental Geology in the 21St Century: A Workshop Report

NASA Astrophysics Data System (ADS)

Mogk, D. W.; Wiese, K.; Castendyk, D.; McDaris, J. R.

2012-12-01

Environmental Geology encompasses a range of topics that include geohazards, natural resources, issues such as climate change, human health, and environmental policy. Instruction in Environmental Geology provides students the opportunity to address the grand challenges facing humanity regarding how to live sustainably and responsibly on Earth. Instruction in Environmental Geology ranges from dedicated introductory courses, instructional modules in upper division Earth Science "core" classes, to courses in related disciplines such as environmental science, ecology, and the social and political sciences. To explore the opportunities of teaching Environmental Geology in all these contexts, the On the Cutting Edge program convened a workshop in June 2012 to bring together instructors representing a diversity of instructional settings. The goals of the workshop were to: 1) Share innovative teaching methods, approaches, and activities for teaching Environmental Geology and share ideas on how to teach in various contexts. 2) Examine where and how environmental geology topics are taught in the geoscience curriculum from introductory courses for non-majors to "core" geoscience courses for majors. 3) Consider the ways that Environmental Geology courses and topical materials can contribute to public science literacy, particularly how to make personal and societal decisions about the range of issues facing humanity and to live responsibly and sustainably on this planet. 4) Develop a list of best practices for integrating emerging environmental issues, recent natural disasters, and issues related to natural resources into course work and identifying how scientific data and research outcomes can inform public discourse on topical issues. 5) Develop strategies to reach under-represented groups and expand the diversity of students who enroll in our courses. 6) Identify topics of high interest and need for future development as teaching modules and courses. The workshop program included keynote talks, small group discussion sessions, interactive demonstrations, and opportunities to network and develop ideas for new instructional resources. The participants also reviewed over 300 teaching activities, and contributed to additional online resources focused on Environmental Geology. Field trips demonstrated teaching activities about environmental issues in local contexts. All workshop presentations, discussion summaries, teaching activity collections and related on-line resources are available on the workshop website. Faculty are encouraged to submit additional examples of Environmental Geology instructional resources.

The effect of ketogenic diet in an animal model of autism induced by prenatal exposure to valproic acid.

Autism spectrum disorder (ASD) is characterized by impairments in social interaction and communication, and by restricted repetitive behaviors and interests. Its etiology is still unknown, but different environmental factors during pregnancy, such as exposure to valproic acid (VPA), are associated with high incidence of ASD in children. In this context, prenatal exposure to VPA in rodents has been used as a reliable model of ASD. Ketogenic diet (KD) is an alternative therapeutic option for refractory epilepsy; however, the effects of this approach in ASD-like behavior need to be evaluated. We conducted a behavioral assessment of the effects of KD in the VPA model of autism. Pregnant animals received a single-intraperitoneal injection of 600 mg/kg VPA, and their offspring were separated into four groups: (1) control group with standard diet (C-SD), (2) control group with ketogenic diet (C-KD), (3) VPA group with standard diet (VPA-SD), and (4) VPA group with ketogenic diet (VPA-KD). When compared with the control group, VPA animals presented increased social impairment, repetitive behavior and higher nociceptive threshold. Interestingly, the VPA group fed with KD presented improvements in social behavior. These mice displayed higher scores in sociability index and social novelty index when compared with the SD-fed VPA mice. VPA mice chronically exposed to a KD presented behavioral improvements; however, the mechanism by which KD improves ASD-like features needs to be further investigated. In conclusion, the present study reinforces the potential use of KD as a treatment for the core deficits of ASD.

Seismology program; California Division of Mines and Geology

1981-01-01

The year 1980 marked the centennial of the California Division of Mines and Geology (CDMG) and a decade of the Division's involvement in seismology. Factors which contributed to the formation of a Seismology Group within CDMG included increased concerns for environmental and earthquake safety, interest in earthquake prediction, the 1971 San Fernando earthquake and the 1973 publication by CDMG of an urban geology master plan for California. Reasons to be concerned about California's earthquake problem are demonstrated by the accompanying table and the figures. Recent seismicity in California, the Southern California uplift reflecting changes in crustal strain, and other possible earthquake precursors have heightened concern among scientific and governmental groups about the possible occurrence of a major damaging earthquake )M>7) in California.

Minchin, Robert F., E-mail: rminchin@naic.edu

I investigate whether it is possible to reconcile the recent Arecibo Legacy Fast Arecibo L-band Feed Array (ALFALFA) observation that the neutral hydrogen mass function (HIMF) across different galactic densities has the same, non-flat, faint-end slope, with observations of isolated galaxies and many galaxy groups that show their HIMFs to have flat faint-end slopes. I find that a fairly simple model in which the position of the knee in the mass function of each individual group is allowed to vary is able to account for both of these observations. If this model reflects reality, the ALFALFA results point to anmore » interesting “conspiracy” whereby the differing group HIMFs always sum up to form global HIMFs with the same faint-end slope in different environments. More generally, this result implies that global environmental HIMFs do not necessarily reflect the HIMFs in individual groups belonging to that environment and cannot be used to directly measure variations in group-specific HIMFs with environment.« less

Stringency of workplace air contaminant exposure limits: a case study of OSHA risk management.

PubMed

Hakes, J K

1999-12-01

Political context may play a large role in influencing the efficiency of environmental and health regulations. This case study uses data from a 1989 update of the Occupational Safety and Health Administration (OSHA) Permissible Exposure Limits (PELs) program to determine the relative effects of legislative mandates, costly acquisition of information by the agency, and pressure applied by special interest groups upon exposure standards. The empirical analysis suggests that federal agencies successfully thwart legislative attempts to limit agency discretion, and that agencies exercise bounded rationality by placing greater emphasis on more easily obtained information. The 1989 PELs were less significantly related to more costly information, contained "safety factors" for chemicals presenting relatively more ambiguous risks, and the proposed standard stringencies showed evidence of being influenced by vying industry and labor interests.

Military service and combat exposure are risk factors for smoking. Although evidence suggests that veterans are interested in tobacco use cessation, little is known about their reasons for quitting, treatment preferences, and perceived barriers to effective tobacco use cessation treatment. Our study objective was to elicit perspectives of Iraq- and Afghanistan-era veterans who had not yet quit smoking postdeployment to inform the development of smoking cessation services for this veteran cohort. We conducted 3 focus groups among 20 participants in October 2006 at the Durham Veterans Affairs Medical Center to explore issues on tobacco use and smoking cessation for Iraq- and Afghanistan-era veterans who continued to smoke postdeployment. We used qualitative content analysis to identify major themes and organize data. Veterans expressed the belief that smoking was a normalized part of military life and described multiple perceived benefits of smoking. Although veterans expressed a high level of interest in quitting, they listed several behavioral, situational, and environmental triggers that derailed smoking cessation. They expressed interest in such cessation treatment features as flexible scheduling, free nicotine replacement therapy, peer support, and family inclusion in treatment. Our results indicate that the newest cohort of veterans perceives smoking as endemic in military service. However, they want to quit smoking and identified several personal and environmental obstacles that make smoking cessation difficult. Our findings may inform programmatic efforts to increase successful quit attempts in this unique veteran population.

2002-09-01

The apparently unresolvable differences between managing national defense and local conservation, public recreation, and scientific research can be overcome through an advisory committee, with a strong and dedicated entity to drive the processes of governance and change. The case of the Garden Island Environmental Advisory Committee shows how the organizational and political difficulties of integrating state interests and federal concerns were met. Garden Island, off the coast of Perth, the capital of the State of Western Australia, is a base for the Royal Australian Navy which is administered by the federal Department of Defence. Examples are given of the committee's approach to integrated environmental management and the implementation of the Navy's environmental policy.

The primary objective of this project was to engage members of the public in an active and balanced deliberative discussion about the social, ethical, legal, environmental, and policy issues arising from nanotechnologies. A second but equally important objective was to interest members of the public in learning more about science and technology and nanotechnology specifically by understanding how it will affect their lives. The objectives were met through a series of electronic and face-to-face citizen forums conducted in conjunction with three Fred Friendly Seminars being taped on the University of California, Berkeley campus in partnership with Lawrence Hall of Sciencemore » (this forum was conducted in partnership with the St. Louis Science Center); the Boston Museum of Science in Boston, MA; and the State Museum of South Carolina in Columbia, South Carolina. The topical area for each forum paralleled the content of the Fred Friendly Seminars series being taped at each location, but specific topics/issues were drawn from the concerns and interests of the communities. The three topical areas included Environmental Impact (St. Louis), Privacy vs. Security (Boston), and Health and Enhancement (Columbia). The PI and project leader worked with the local science centers to identify stakeholder groups, such as academic, corporate and government scientists; environmental advocates; business leaders; science and technology journalists; and public policy makers within each community. Representatives from each group along with members of the general public were invited to participate in a series of on line and in person deliberations that were designed to provide basic information about the science, its potential benefits and risks, and avenues for public participation in policy formulation. On line resources were designed and managed by ScienceVIEW at Lawrence Hall of Science and Earth & Sky, Inc. The activities at each site were evaluated by Inverness Research Associates to assess whether they have achieved the objectives.« less

Abstract Anurans have close associations with environmental conditions and therefore represent an interesting vertebrate group for examining how resource availability and environmental variables influence species diversity. Associations between habitat heterogeneity and anuran species diversity were tested in the Restinga landscapes of the Parnaíba River delta in northeastern Brazil. Twenty-one anuran species were sampled in the rainy season during monthly excursions (December 2015 to June 2016) into areas of Restinga on two islands in the Parnaíba River delta. The fourth highest anuran diversity was found in this type of environment in Brazil and is the third in northeastern Brazil. Microenvironments, characterized by a combination of vernal pools with different vegetational and physical structures, better explained anuran species composition in the Parnaíba River delta.

Organic agriculture is the highest environmentally valuable agricultural system, and has strategic importance at national level that goes beyond the interests of agricultural sector. In this paper we address development of organic farming simulation model based on a system dynamics methodology (SD). The system incorporates relevant variables, which affect the development of the organic farming. The group decision support system (GDSS) was used in order to identify most relevant variables for construction of causal loop diagram and further model development. The model seeks answers to strategic questions related to the level of organically utilized area, levels of production and crop selection in a long term dynamic context and will be used for simulation of different policy scenarios for organic farming and their impact on economic and environmental parameters of organic production at an aggregate level.

Some diseases in the community have a relationship with the environment. Therefore, medical students need to be exposed early to environmental problems in the community. The aim of this paper is to explain the role of field studies for medical students in introducing environmental health problems at an early stage. Field studies were applied by the Department of Public Health in 2005-2006 and 164 students from Semester II, which come from two classes, were required to join it. The portion score of the field study was 10%. Each class consisted of ten groups. Each group consisted of approximately eight students. Each group took different topics/targets of observation. These included ecological farming, household waste management, communal waste management, family medicine plants, food home industry, food street vendors, slaughterhouses, traditional markets, management of communal waste water, and recycling home industry. Each group observed in a community and interviewed related informants. Students were required to make a report and present it in their class. At the end of the exam, students were required to assess the benefit of this activity using a range of 1 (minimal) to 5 (maximal). The students considered the benefits of the field study method, giving an average score of 3.9 and 3.95 for presentation and discussion in class. Some students proposed to maintain field studies and discussion, and to conduct this method every semester with more time. Other students suggested that a lecturer accompany them in the field. Several students regretted unpunctual discussion time that reduced lecture time. The learning model of field study increased the students' interest in the subject of public health.

Measuring the Interest of German Students in Agriculture: the Role of Knowledge, Nature Experience, Disgust, and Gender

NASA Astrophysics Data System (ADS)

Bickel, Malte; Strack, Micha; Bögeholz, Susanne

2015-06-01

Modern knowledge-based societies, especially their younger members, have largely lost their bonds to farming. However, learning about agriculture and its interrelations with environmental issues may be facilitated by students' individual interests in agriculture. To date, an adequate instrument to investigate agricultural interests has been lacking. Research has infrequently considered students' interest in agricultural content areas as well as influencing factors on students' agricultural interests. In this study, a factorial design of agricultural interests was developed combining five agricultural content areas and four components of individual interest. The instrument was validated with German fifth and sixth graders ( N = 1,085) using a variance decomposition confirmatory factor analysis model. The results demonstrated a second-order factor of general agricultural interest, with animal husbandry, arable farming, vegetable and fruit cropping, primary food processing, and agricultural engineering as discrete content areas of agricultural interest. Multiple regression analyses demonstrated that prior knowledge, garden experience, and disgust sensitivity are predictors of general agricultural interest. In addition, gender influenced interest in four of the five agricultural content areas. Implications are directed at researchers, teachers, and environmental educators concerning how to trigger and develop pupils' agricultural interests.

Biodegradation of fluorinated alkyl substances.

PubMed

Frömel, Tobias; Knepper, Thomas P

2010-01-01

The incorporation of fluorine into organic molecules entails both positive and adverse effects. Although fluorine imparts positive and unique properties such as water-and oil-repellency and chemical stability, adverse effects often pervade members of this compound class. A striking property of long perfluoroalkyl chains is their very pronounced environmental persistence. The present review is the first one designed to summarize recent accomplishments in the field of biodegradation of fluorine-containing surfactants, their metabolites, and structural analogs. The pronounced scientific and public interest in these chemicals has given impetus to undertake numerous degradation studies to assess the sources and origins of different fluorinated analog chemical known to exist in the environment. It was shown that biodegradation plays an important role in understanding how fluorinated substances reach the environment and, once they do, what their fate is. Today, PFOS and PFOA are ubiquitously detected as environmental contaminants. Their prominence as contaminants is mainly due to their extreme persistence, which is linked to their perfluoroalkyl chain length. It appears that desulfonation of a highly fluorinated surfactants can be achieved if an α-situated H atom, in relation to the sulfonate group, is present, at least under sulfur-limiting conditions. Molecules that are less heavily fluorinated can show very complex metabolic behavior, as is the case for fluorotelomer alcohols. These compounds are degraded via different but simultaneous pathways, which produce different stable metabolites, one of which is the respective perfluoroalkanoate (8:2-FTOH is transformed to PFOA). Preliminary screening tests indicate that fluorinated functional groups, such as the trifluoromethoxy group and the p-(trifluoromethyl)phenoxy group, may be useful implementations in novel, environmentally benign fluorosurfactants. More specifically, trifluoromethoxy groups constitute a substitute for those that have been used in the past; this functionality is degradable when it appears in structures that are normally subject to biodegradation. Other compounds tested did not meet this criterion. Interdisciplinary investigations on fluorinated surfactants are still very much needed and will certainly continue during the next many years. For instance, the role of fluorinated polymers in contributing small fluorinated molecules to the environmental burden still has not been fully understood.

Lessons of Researcher-Teacher Co-design of an Environmental Health Afterschool Club Curriculum

NASA Astrophysics Data System (ADS)

Hundal, Savreen; Levin, Daniel M.; Keselman, Alla

2014-06-01

This paper addresses the impact of teachers' beliefs about argumentation and their community of practice framed views of teaching on co-designing an environmental health afterschool club curriculum with researchers. Our team collaborated with a group of four middle school teachers, asking them to co-design a club that would facilitate (1) students' understanding of environmental health, (2) use of electronic resources, and (3) argumentation skills. The process included researcher-led sessions emphasizing the importance of argumentation to science and teacher-led curriculum design sessions. The qualitative analysis of the meetings and teacher interview transcripts suggests that while teachers viewed argumentation as important, its practice was relegated to the background by the focus on student engagement and perceived logistical and systemic constraints. The paper concludes that in addition to stressing relevance of argumentation to science learning, researchers involved in co-design need to emphasize the potential of argumentation to engage students and to fit into science curriculum. The analysis also reveals teacher-participants' views of environmental health as an important area of middle school education, relevant to students' lives, linkable to the existing curriculum, essential for informed citizenship, and capable of inspiring interest in science. These findings underscore the importance of integrating environmental health into science education and advocating for its inclusion in informal and formal educational settings.

Wells, Ellen M

2017-06-01

This review describes published literature providing evidence for financial conflicts of interest in environmental and occupational health research. Secondary goals were to describe evidence that (a) utilized quantitative methods to evaluate the association of conflicts with study outcomes, and (b) assessed undisclosed as well as disclosed conflicts of interest. Forty-three studies were identified which contained descriptions of the impact of financial conflicts of interest on research results; 11 of these conducted quantitative analyses to demonstrate these relationships. All 11 articles which quantified associations identified significant associations of the presence of financial conflicts of interest with study findings. In studies which measured undisclosed conflicts, these comprised a substantial proportion of all conflicts. Suggestions for improving understanding and interpretation of research results are presented.

Meinhold, A.F.; DePhillips, M.P.; Holtzman, S.

1996-03-01

Potential human health and environmental impacts from discharges of produced water to the Gulf of Mexico are of concern to regulators at the State and Federal levels, the public, environmental interest groups and industry. Current and proposed regulations require a zero discharge limit for coastal facilities, based primarily on studies in low energy, poorly flushed environments. However, produced water discharges in coastal Louisiana include a number of open bay sites, where potential human health and environmental impacts are likely to be smaller than those demonstrated for low energy canal environments, but greater than the minimal impacts associated with offshore discharges.more » Additional data and assessments are needed to support risk managers at the State and Federal levels in the development of regulations that protect human health and the environment without unnecessary cost to the economic welfare of the region and the nation. This project supports the Natural Gas and Oil Initiative objectives to: (1) improve coordination on environmental research; (2) streamline State and Federal regulation; (3) enhance State, and Federal regulatory decision making capability; (4) enhance dialogue through industry/government/public partnerships; and (5) work with States and Native American Tribes.« less

DEVELOPMENT OF A PASSIVE, IN SITU, INTEGRATIVE ...

EPA Pesticide Factsheets

Until recently, hydrophobic, bioconcentratable compounds have been the primary focus of most environmental organic contaminant investigations, There is an increasing realization that a holistic hazard assessment of complex environmental contaminant mixtures requires data on the concentrations of hydrophilic organic contaminants as well. This group of compounds includes a wide variety of chemicals, including potentially endocrine disrupting and estrogenic contaminants which have been shown to contribute to numerous abnormalities such as impaired reproduction in aquatic organisms exposed in environmental waters. To address this issue, we developed a passive, in situ, sampling device (the Polar Organic Chemical Integrative Sampler or POCIS) which integratively concentrates trace levels of complex mixtures of hydrophilic environmental contaminants, enables the determination of their time-weighted average water concentrations and provides a screening assessment of the toxicological significance of the complex mixture of waterborne contaminants. Using a prototype sampler (effective membrane sampling surface area = 18.2 cm 2) linear uptake of selected herbicides and pharmaceuticals was observed for up to 56 days. Estimation of the ambient water concentrations of chemicals of interest is achieved by using appropriate uptake models and determination of POCIS chemical sampling rates. The research focused on in the subtasks is the development and application of state-of

Small-Magnitude Effect Sizes in Epigenetic End Points are Important in Children’s Environmental Health Studies: The Children’s Environmental Health and Disease Prevention Research Center’s Epigenetics Working Group

Background: Characterization of the epigenome is a primary interest for children’s environmental health researchers studying the environmental influences on human populations, particularly those studying the role of pregnancy and early-life exposures on later-in-life health outcomes. Objectives: Our objective was to consider the state of the science in environmental epigenetics research and to focus on DNA methylation and the collective observations of many studies being conducted within the Children’s Environmental Health and Disease Prevention Research Centers, as they relate to the Developmental Origins of Health and Disease (DOHaD) hypothesis. Methods: We address the current laboratory and statistical tools available for epigenetic analyses, discuss methods for validation and interpretation of findings, particularly when magnitudes of effect are small, question the functional relevance of findings, and discuss the future for environmental epigenetics research. Discussion: A common finding in environmental epigenetic studies is the small-magnitude epigenetic effect sizes that result from such exposures. Although it is reasonable and necessary that we question the relevance of such small effects, we present examples in which small effects persist and have been replicated across populations and across time. We encourage a critical discourse on the interpretation of such small changes and further research on their functional relevance for children’s health. Conclusion: The dynamic nature of the epigenome will require an emphasis on future longitudinal studies in which the epigenome is profiled over time, over changing environmental exposures, and over generations to better understand the multiple ways in which the epigenome may respond to environmental stimuli.

Influences on Adoption of Greenhouse Gas Reduction Targets among US States, 1998-2008

PubMed Central

Cale, Tabitha M.; Reams, Margaret A.

2016-01-01

While the United States has not established federal regulations for greenhouse gas (GHG) reduction targets, many US states have adopted their own standards and guidelines. In this study we examine state adoption of targets for GHG reductions during the ten-year period of 1998–2008, and identify factors that explain variation in target adoption. Potential influences are drawn from research from the public policy formulation and diffusion literature, and from studies specific to climate policy adoption. Potential influences on GHG reduction efforts among US states include socioeconomic attributes of residents, political and ideological orientations of citizens and state government, interest group activities, environmental pressures, and proximity to other states that have adopted GHG reduction targets. The findings of the multinomial logistic regression analysis indicate that states are more likely to adopt GHG reduction targets if they share a border with another state with a similar climate program and if their citizens are more ideologically liberal. Other factors including socioeconomic resources and interest group activities were not found to be associated with policy adoption. The findings yield insights into the conditions under which states are more likely to take action to reduce GHG’s, and are relevant both to state policy makers and residents with an interest in climate planning, and for researchers attempting to estimate future greenhouse gas reduction scenarios.

A social competence intervention for young children with high functioning autism and Asperger syndrome: a pilot study.

PubMed

Minne, Elizabeth Portman; Semrud-Clikeman, Margaret

2012-11-01

The key features of Asperger Syndrome (AS) and high functioning autism (HFA) include marked and sustained impairment in social interactions. A multi-session, small group program was developed to increase social perception based on the assumption perceptual or interpretive problems underlying these social difficulties. Additionally, the group format espoused a play therapy orientation and the use of sociodramatic play was the primary therapeutic modality used. Qualitative analyses of the data resulted in an explanation of the key changes in social interactions that took place through the course of the intervention. Although each participant's experience in this group was unique, all children in this program demonstrated improvements in their social interactions, as they experienced development both emotionally and behaviorally. Findings suggest that, despite their rigid interests and behavior patterns, the social limitations of these children improved when provided with the necessary environmental resources.

Mental representation changes the evaluation of green product benefits

NASA Astrophysics Data System (ADS)

Goldsmith, Kelly; Newman, George E.; Dhar, Ravi

2016-09-01

Although campaigns designed to promote pro-environmental behaviours increasingly highlight self-interest, recent research suggests that such appeals may not always be effective. For example, individuals are more likely to check their tyre pressure when prompted with self-transcendent (that is, benefits to the environment) versus economic motives; and, self-transcendent appeals are more likely to promote recycling behaviours than self-interested appeals. The present experiments identify an important psychological factor that helps to explain when highlighting economic benefits will be more or less effective in encouraging pro-environmental behaviours. Specifically, we demonstrate that highlighting economic benefits (for example, the money a consumer can save) reduces consumer interest in sustainable products when individuals are in more abstract mindsets compared with when the evaluation is more immediate (that is, their mindset is more concrete). Further, we provide evidence that this shift in interest is driven by the lack of `fit' between abstract thinking and economic motivations, in the context of pro-environmental behaviour.

Does race matters in consumers' stated preferences for water and carbon footprints labelled food products? Insights from black and white South Africans

NASA Astrophysics Data System (ADS)

Owusu-Sekyere, Enoch; Jordaan, Henry

2017-04-01

In recent years, governments, policy-makers, and managers of private food companies and agribusinesses are interested in understanding how consumers will react to environmentally sustainable attributes and information on food product labels. This study examines consumers' stated preferences for water and carbon footprints labelled food products from the viewpoint of black and white South Africans. Discrete choice experimental data was collected from black and white consumers to possibly assess cross-ethnic variations in preferences for environmentally sustainable products. Two widely purchased livestock products were chosen for the choice experiment. We found that consumers' preferences for environmentally sustainable attributes vary significantly between black and white South Africans. Our findings revealed that there are profound heterogeneous consumer segments within black and white respondents. The heterogeneity within both sub-samples is better explained at the segment level, rather than at individual level. For both product categories, the findings revealed that there are more distinct consumer segments among black respondents, relative to white respondents. The black respondents consist of water sustainability advocates, carbon reduction advocates, keen environmentalist and environmental neutrals. The white respondents entail keen environmentalist, environmental cynics, and environmental neutrals. The inherent significant variations in preferences for environmentally sustainable attributes across segments and racial groups would help in formulating feasible, and segment-specific environmental sustainability policies and marketing strategies aimed at changing consumers' attitude towards environmentally sustainable products. Demographic targeting of consumer segments, sustainability awareness and segment-specific educational campaigns meant to enhance subjective and objective knowledge on environmental sustainability are important tools for food companies and agribusinesses to promote and market environmentally sustainable food products.

Older Adults' Perceptions of Nutrition as Protective Against Detrimental Effects of Environmental Pollution.

Dunn, Kristina; Gaetke, Lisa; Stephenson, Tammy; Brewer, Dawn

2017-08-01

The aging process makes older adults vulnerable to the detrimental health effects of environmental contaminants. Our study assessed older adults' perceptions regarding diet being protective against environmental contaminants, their levels of concern about exposure, and their interest in learning about protective food-related strategies. A needs assessment to collect such information has not been conducted among older adults. Health fair survey results showed that they perceived diet as beneficial against contaminants, were concerned about health implications of exposure, and were interested in learning how to protect health through diet-related strategies. Results suggest that a nutrition-focused curriculum addressing how dietary strategies can help protect against environmental contaminants is needed for Extension professionals.

Stakeholder Participation in Marine Spatial Plan Making Process in Lampung Province

Asirin; Asbi, A. M.; Pakpahan, V. H.

2018-05-01

Lampung Province has coastal areas, seas and small islands facing conflicts of interest between tourism, conservation areas for defense, environmental conservation, and the threat of unsustainable marine resource utilization. Indonesia (including Lampung Province) has committed itself to achieving the objectives of conservation and sustainable use of oceans, seas and marine resources in view of sustainable development. One of the instruments used to achieve this goal is by using marine spatial planning (MSP). The purpose of this research was to analyse the marine spatial plan making process in Lampung Province. This research also evaluated the participation process and participation level based on plan-making process criteria and the stakeholder participation ladder. This research can be useful as a recommendation in the evaluation step to improve the plan-making process in order to address conflicts of interest between various related interest groups, so that planning can be accomplished with the involvement of all relevant parties to reach consensus on how to achieve a sustainable marine environment. This research used a qualitative research method as well as a case study approach. The scope of this study was limited by the conceptual framework of marine spatial planning and the stakeholder participation ladder. The authors recommend study of the preparation of marine spatial planning in addition to a technocratic approach considering the results of the study aspects of spatial allocation and physical aspects of marine resources, while prioritizing building consensus among various interest groups related to the utilization of marine resources. Thus, it is necessary to develop technical steps to build consensus in the marine spatial plan-making process.

Past Actions as Self-Signals: How Acting in a Self-Interested Way Influences Environmental Decision Making.

In the last few decades, awareness of environmental issues has increased significantly. Little has changed, however, in human activities contributing to environmental damage. Why is it so difficult for us to change our behavior in a domain that is clearly so important to the future of humanity? Here we propose and test the possibility that self-signaling, the way we view ourselves based on our past behaviors, is one of the factors contributing to the difficulty of taking environmental action. In three experiments, we show that previous self-interested thoughts or behaviors serve as important signals that hinder the likelihood of acting in line with an individual's reported concern for the environment. This study not only helps explain the gap between environmental awareness and action, but also suggests alternative strategies for policymakers and environmental agencies to promote proenvironmental behavior.

Wine pomace (WP) is one of the agricultural byproducts that has received most attention from food scientists due to the wide range of interesting compounds that remain after the winemaking process. Different powdered products rich in phenolic compounds, with interesting antioxidant and antimicrobial activities, were obtained from WP by applying processes that are both environmentally friendly and economically affordable for the food industry. The products obtained showed high global antioxidant activities (ABTS assay), successfully delayed the onset of lipid oxidation in the Rancimat test, and showed different antimicrobial properties. Products derived from seed-free WP showed bactericidal effects against total aerobic mesophilic bacteria (TAMB) and lactic acid bacteria (LAB) and inhibited Enterobacteriaceae growth completely. The product derived from whole WP presented bacteriostatic activity against the three microorganism groups tested, whereas the product obtained from grape seed promoted TAMB and LAB growth but delayed Enterobacteriaceae proliferation.

Health professions students interested in future rural practice locations spend a week learning about and investigating all aspects of small town personal, professional and community life. This augments the mainly clinical experience provided by clinical rotations they complete as part of their professional academic training program. Students from professional programs in medicine, physician assistant, pharmacy, nursing, public health and psychology travel to a small community, receive an orientation and in small interprofessional groups investigate health care, education, government, law enforcement, public health, economy and natural resources. Participants report that the experience raises their interest in future rural practice, answers questions they have about rural life and enhances their understanding of the issues they must learn more about before making a career location choice. The interdisciplinary rural immersion program provides students with the time, structure and permission to move out of their clinical 'comfort zone' and think about the cultural, economic and environmental aspects of rural life and work.

Addressing global sustainability challenges--including climate change, resource depletion, and ecosystem loss--is beyond the individual capabilities of even the largest companies. To tackle these threats, and unleash new value, companies and other stakeholders must collaborate in new ways that treat fragile and complex ecosystems as a whole. In this article, the authors draw on cases including the Latin American Water Funds Partnership, the Sustainable Apparel Coalition (led by Nike, Patagonia, and Walmart), and Action to Accelerate Recycling (a partnership between Alcoa, consumer packaged goods companies, and local governments, among others) to describe four new collaboration models that create shared value and address environmental protection across the value stream. Optimal collaborations focus on improving either business processes or outcomes. They start with a small group of key organizations, bring in project management expertise, link self-interest to shared interest, encourage productive competition, create quick wins, and, above all, build and maintain trust.

Possible ancestral structure in human populations.

Determining the evolutionary relationships between fossil hominid groups such as Neanderthals and modern humans has been a question of enduring interest in human evolutionary genetics. Here we present a new method for addressing whether archaic human groups contributed to the modern gene pool (called ancient admixture), using the patterns of variation in contemporary human populations. Our method improves on previous work by explicitly accounting for recent population history before performing the analyses. Using sequence data from the Environmental Genome Project, we find strong evidence for ancient admixture in both a European and a West African population (p approximately 10(-7)), with contributions to the modern gene pool of at least 5%. While Neanderthals form an obvious archaic source population candidate in Europe, there is not yet a clear source population candidate in West Africa.

The Brazilian Twin Registry (BTR) was established in 2013 and has impelled twin research in South America. The main aim of the initiative was to create a resource that would be accessible to the Brazilian scientific community as well as international researchers interested in the investigation of the contribution of genetic and environmental factors in the development of common diseases, phenotypes, and human behavior traits. The BTR is a joint effort between academic and governmental institutions from Brazil and Australia. The collaboration includes the Federal University of Minas Gerais (UFMG) in Brazil, the University of Sydney and University of Melbourne in Australia, the Australian Twin Registry, as well as the research foundations CNPq and CAPES in Brazil. The BTR is a member of the International Network of Twin Registries. Recruitment strategies used to register twins have been through participation in a longitudinal study investigating genetic and environmental factors for low back pain occurrence, and from a variety of sources including media campaigns and social networking. Currently, 291 twins are registered in the BTR, with data on demographics, zygosity, anthropometrics, and health history having been collected from 151 twins using a standardized self-reported questionnaire. Future BTR plans include the registration of thousands of Brazilian twins identified from different sources and collaborate nationally and internationally with other research groups interested on twin studies.

`No One Should Destroy the Forest': Using photo-based vignette interviews to understand Kenyan teachers' views of the environment

2014-11-01

In the midst of the current environmental crisis, scientists, academics, authors, and politicians worldwide are urging citizens to create sustainable communities. However, there is little capability to build a sustainable society without an informed, active, and engaged populous. This requires more than just environmentally knowledgeable citizens. It requires a society that understands the principles of the environment and can also exemplify them in daily life. In order to create a more environmentally literate world, there has been a push for environmental education integrated into schools. This qualitative study sought to examine Kenyan teachers' perspectives on the human-nature interaction by conducting vignette focus-group interviews. It is a subject not widely explored but vital for conservation not only in this area, but also other areas that seek to have an ecological informed populous. The vignettes were created using photographs and explanations of the photographs that the participants collected and emailed to the authors. For the focus-group vignette interviews, there were a total of 55 participants (30 females and 25 males). After InVivo analysis, we had 6 codes (resentment, pride, perils, blame, pragmatism, and self-interested) within 3 major themes. This study has implications for informing science education to combat these traditions of subjecting students to a science curriculum that demotes Kenyan cultural heritage and lifestyle. By incorporating local knowledge such as the ideas discussed in this paper into Kenyan science education, Kenyans can reach one of most challenging objectives of education, which is to produce children who are fundamentally aware of their environment.

Waste disposal in the 21st century and diabetes technology: a little coffee (cup) or beer (can) with that insulin infusion (set).

The advent of single-use disposable syringes along with myriad similar products for the health care industry has raised interest in the impact of these devices on the environment. Interest does not stop at impact of the device, but also includes associated pharmaceutical agents. Across the spectrum of health care, providers as well as end users of products are assessing the impact of product design and contents upon land, air, and water. In this issue of Journal of Diabetes Science and Technology, Pfützner and colleagues tackle the issue by focusing on a product for the diabetes patient. As environmental sustainability has become part of the evaluation process of many products, their assessment sheds some interesting light on the impact of a group of devices when compared and contrasted against the ever-popular disposable coffee cup or beer/soda aluminum can. Regional variations in waste disposal practices need to be understood when conducting these types of assessments. © 2011 Diabetes Technology Society.

The Costa Rica GLOBE (Global Learning and Observations to Benefit the Environment) Project as a Learning Science Environment

2015-12-01

GLOBE is a global educational program for elementary and high school levels, and its main purpose in Costa Rica is to develop scientific thinking and interest for science in high school students through hydrology research projects that allow them to relate science with environmental issues in their communities. Youth between 12 and 17 years old from public schools participate in science clubs outside of their regular school schedule. A comparison study was performed between different groups, in order to assess GLOBE's applicability as a learning science atmosphere and the motivation and interest it generates in students toward science. Internationally applied scales were used as tools for measuring such indicators, adapted to the Costa Rican context. The results provide evidence statistically significant that the students perceive the GLOBE atmosphere as an enriched environment for science learning in comparison with the traditional science class. Moreover, students feel more confident, motivated and interested in science than their peers who do not participate in the project. However, the results were not statistically significant in this last respect.

Environmental problem-solving: Psychosocial factors

NASA Astrophysics Data System (ADS)

Miller, Alan

1982-11-01

This is a study of individual differences in environmental problem-solving, the probable roots of these differences, and their implications for the education of resource professionals. A group of student Resource Managers were required to elaborate their conception of a complex resource issue (Spruce Budworm management) and to generate some ideas on management policy. Of particular interest was the way in which subjects dealt with the psychosocial aspects of the problem. A structural and content analysis of responses indicated a predominance of relatively compartmentalized styles, a technological orientation, and a tendency to ignore psychosocial issues. A relationship between problem-solving behavior and personal (psychosocial) style was established which, in the context of other evidence, suggests that problem-solving behavior is influenced by more deep seated personality factors. The educational implication drawn was that problem-solving cannot be viewed simply as an intellectual-technical activity but one that involves, and requires the education of, the whole person.

Segregating Variation in the Polycomb Group Gene cramped Alters the Effect of Temperature on Multiple Traits

Gibert, Jean-Michel; Karch, François; Schlötterer, Christian

2011-01-01

The phenotype produced by a given genotype can be strongly modulated by environmental conditions. Therefore, natural populations continuously adapt to environment heterogeneity to maintain optimal phenotypes. It generates a high genetic variation in environment-sensitive gene networks, which is thought to facilitate evolution. Here we analyze the chromatin regulator crm, identified as a candidate for adaptation of Drosophila melanogaster to northern latitudes. We show that crm contributes to environmental canalization. In particular, crm modulates the effect of temperature on a genomic region encoding Hedgehog and Wingless signaling effectors. crm affects this region through both constitutive heterochromatin and Polycomb silencing. Furthermore, we show that crm European and African natural variants shift the reaction norms of plastic traits. Interestingly, traits modulated by crm natural variants can differ markedly between Drosophila species, suggesting that temperature adaptation facilitates their evolution. PMID:21283785

Hydrogen Sulfide and Ionic Liquids: Absorption, Separation, and Oxidation.

Economical and environmental concerns are the main motivations for development of energy-efficient processes and new eco-friendly materials for the capture of greenhouse gases. Currently, H 2 S capture is dominated by physical and/or chemical absorption technologies, which are, however, energy intensive and often problematic from an environmental point of view due to emission of volatile solvent components. Ionic liquids have been proposed as a promising alternative to conventional solvents because of their low volatility and other interesting properties. The aim of the present review paper is to provide a detailed overview of the achievements and difficulties that have been encountered in finding suitable ionic liquids for H 2 S capture. The effect of ionic liquid anions, cations, and functional groups on the H 2 S absorption, separation, and oxidation are highlighted. Recent developments on yet scarcely available molecular simulations and on the development of robust predictive methods are also discussed.

Chitin (a biopolymer obtained from shellfish industry) was used as precursor for the production of biochars obtained via pyrolysis treatments performed at mild conditions (in the 290-540 °C range). Biochars were physicochemical characterized in order to evaluate the pyrolysis-induced effects in terms of both functional groups and material structure. Moreover, such carbonaceous materials were tested as adsorbent substrates for the removal of target molecules from aqueous environment as well as in solid-gas experiments, to measure the adsorption capacities and selectivity toward CO2. Lastly, biochars were also investigated as possible cathode materials in sustainable and low-cost electrochemical energy storage devices, such as lithium-sulphur (Li-S) batteries. Interestingly, experimental results evidenced that such chitin-derived biochars obtained via pyrolysis at mild conditions are sustainable, low-cost and easy scalable alternative materials suitable for both environmental and energetic applications.

Interest in the sustainability of farming practices has increased in response to environmental problems associated with conventional agricultural management often adopted for the production of herbaceous crops, ornamentals, and fruit crops. Availability of measures of the status of the soil ecosystem is of immediate importance, particularly for environmental assessment and monitoring programs. This study investigated the effects of various irrigation regimes (an example of an agricultural management practice) on the structure of the nematode fauna in a citrus orchard in the sandy ridge area of Central Florida. Ecological measures such as community structure indices, diversity indices, and maturity indices were assessed and related to irrigation intensity. Maturity index was an effective measure in distinguishing differences between irrigation regimes, whereas other indices of community structure were not. Of various nematode genera and trophic groups, only omnivores and the omnivore genera. Aporcelaimellus and Eudorylaimus responded to irrigation treatments.

At-risk students experience higher than normal rates of absenteeism as well as other traumatic experiences which can interfere with the learning process. We have worked to engage a group of students at Malcolm X Shabazz High School in Newark, NJ, in science via a citizen science approach. Their project involved collecting and processing data related to activities of extracellular enzymes in diverse freshwater environments during a 3-day stay at Pocono Environmental Education Center, a residential environmental education center in the Delaware Water Gap National Recreation Area. So far, informal assessments of student outcome suggest that the experience results in students with higher interest in technical subject matter and higher self-confidence in their ability to become professional scientists or engineers. In the future, we plan more formal study of student outcomes using methods outlined in this presentation.

Advances in utilization of renewable substrates for biosurfactant production

PubMed Central

2011-01-01

Biosurfactants are amphiphilic molecules that have both hydrophilic and hydrophobic moieties which partition preferentially at the interfaces such as liquid/liquid, gas/liquid or solid/liquid interfaces. Such characteristics enable emulsifying, foaming, detergency and dispersing properties. Their low toxicity and environmental friendly nature and the wide range of potential industrial applications in bioremediation, health care, oil and food processing industries makes them a highly sought after group of chemical compounds. Interest in them has also been encouraged because of the potential advantages they offer over their synthetic counterparts in many fields spanning environmental, food, biomedical, petrochemical and other industrial applications. Their large scale production and application however are currently restricted by the high cost of production and by the limited understanding of their interactions with cells and with the abiotic environment. In this paper, we review the current knowledge and latest advances in the search for cost effective renewable agro industrial alternative substrates for their production. PMID:21906330

Historical Highlights From 75 Years of the Soil Science Society of America

NASA Astrophysics Data System (ADS)

Brevik, E. C.

2012-04-01

From its official founding on November 18, 1936 to the present day, the Soil Science Society of America (SSSA) has developed a rich and diverse history. SSSA began with 190 members grouped into six sections: 1) physics, 2) chemistry, 3) microbiology, 4) fertility, 5) morphology, and 6) technology. Today SSSA has over 6,000 members who can choose from any of 11 divisions, S1 Soil Physics, S2 Soil Chemistry, S3 Soil Biology and Biochemistry, S4 Soil Fertility and Plant Nutrition, S5 Pedology, S6 Soil and Water Management and Conservation, S7 Forest, Range, and Wildland Soils, S8 Nutrient Management and Soil and Plant Analysis, S9 Soil Mineralogy, S10 Wetland Soils, and S11 Soils and Environmental Quality to represent their primary area(s) of interest. The Society has also gone from being largely agriculturally focused to an eclectic mix of individuals with interests in agriculture, the environment, earth sciences, human interactions, and other diverse areas. At its founding, SSSA sponsored one publication, the Soil Science Society of America Proceedings. Today, SSSA sponsors its descendent, the Soil Science Society of America Journal, as well as Vadose Zone Journal, the Journal of Environmental Quality, Soil Survey Horizons, and the Journal of Natural Resources and Life Science Education. In short, SSSA's history has been one of continued growth over the last 75 years. The future holds many challenges for SSSA and the field of soil science. There are increasing calls to meet with groups other than or in addition to the American Society of Agronomy and the Crop Science Society of America, groups like the Geological Society of America and the Ecological Society of America. Members in SSSA now work in university departments, government agencies, and businesses representing the fields of biology, geology, geography, and archeology, among others, in addition to the traditional agricultural sector. How SSSA handles this diversification of the field and its membership will influence the future of the Society.

Influence of habitat heterogeneity on the community structure of deep-sea harpacticoid communities from a canyon and an escarpment site on the continental rise off California

The sediment-covered deep-sea floor was initially thought to be environmentally homogeneous. Recent work has shown otherwise, and deep-sea ecologists have been searching for ecologically important environmental heterogeneities on different spatial and temporal scales, with particular interest in canyons. Here we report results for harpacticoid copepods from a site at 3262 m depth in the axis of Monterey Canyon and one on an escarpment 46 km away at 3090 m depth. Multivariate community analyses revealed significant differences between sites in community structure. Absolute abundance, the ratio of subadult copepodites to adults, species density, the proportion of the harpacticoid individuals that emerged, and the proportion that lived in tubes were significantly lower at the canyon site than at the escarpment site. The proportion of the harpacticoid individuals that belonged to the surface-dweller life-style group was significantly higher than at the escarpment site. These marked differences imply that ecologically important environmental heterogeneities exist. We speculate that differences between the sites in food conditions and sediment grain-size distributions are among them.

Association and Diffusion of Li(+) in Carboxymethylcellulose Solutions for Environmentally Friendly Li-ion Batteries.

Carboxymethylcellulose (CMC) has been proposed as a polymeric binder for electrodes in environmentally friendly Li-ion batteries. Its physical properties and interaction with Li(+) ions in water are interesting not only from the point of view of electrode preparation-processability in water is one of the main reasons for its environmental friendliness-but also for its possible application in aqueous Li-ion batteries. We combine molecular dynamics simulations and variable-time pulsed field gradient spin-echo (PFGSE) NMR spectroscopy to investigate Li(+) transport in CMC-based solutions. Both the simulations and experimental results show that, at concentrations at which Li-CMC has a gel-like consistency, the Li(+) diffusion coefficient is still very close to that in water. These Li(+) ions interact preferentially with the carboxylate groups of CMC, giving rise to a rich variety of coordination patterns. However, the diffusion of Li(+) in these systems is essentially unrestricted, with a fast, nanosecond-scale exchange of the ions between CMC and the aqueous environment. © 2016 WILEY-VCH Verlag GmbH & Co.

Among all specific environmental pollution the chemical compounds released in the oil refine process seem to hold the biggest interest. At Medical University of Warsaw we have been studying the influence of the Płock petroleum refinery plant pollution to citizens' health status for over 30 years. The high amount of hydrocarbons--including benzene--were presented in emission. One of the study objectives was to analyze death causes in Płock and Kutno and in the Płock area--according to environmental criteria. The population of the non-petrochemic polluted city Kutno was chosen as the control group. The previous analysis in 1984-1993 showed increased lymphatic or erythrocyte line leukaemia mortality in Płock population vs Kutno population. Similar situation was observed between the area of increased environmental petrochemical pollution and non-polluted area. In this article the Potential Years of Life Lost ratio was used to estimate the life deficiency as the measure of health needs due to mentioned neoplasms. Data indicate that the health needs are bigger than the mortality analysis has shown.

Public participation in the development of flood risk management and river basin management plans are explicit components of both the Water Framework and Floods Directives. At the local level, involving communities in land and water management has been found to (i) aid better environmental decision making, (ii) enhance social, economic and environmental benefits, and (iii) increase a sense of ownership. Facilitating the access and exchange of information on the local environment is an important part of this new approach to the land and water management process, which also includes local community stakeholders in decisions about the design and content of the information provided. As part of the Natural Environment Research Council's pilot Environment Virtual Observatory (EVO), the Local Level group are engaging with local community stakeholders in three different catchments in the UK (the rivers Eden, Tarland and Dyfi) to start the process of developing prototype visualisation tools to address the specific land and water management issues identified in each area. Through this local collaboration, we will provide novel visualisation tools through which to communicate complex catchment science outcomes and bring together different sources of environmental data in ways that better meet end-user needs as well as facilitate a far broader participatory approach in environmental decision making. The Local Landscape Visualisation Tools are being evolved iteratively during the project to reflect the needs, interests and capabilities of a wide range of stakeholders. The tools will use the latest concepts and technologies to communicate with and provide opportunities for the provision and exchange of information between the public, government agencies and scientists. This local toolkit will reside within a wider EVO platform that will include national datasets, models and state of the art cloud computer systems. As such, local stakeholder groups are assisting the EVO's development and participating in local decision making alongside policy makers, government agencies and scientists.

Interest in Insects: The Role of Entomology in Environmental Education

PubMed Central

Weeks, Faith J.; Oseto, Christian Y.

2018-01-01

University-based outreach programs have a long history of offering environmental education programs to local schools, but often these lessons are not evaluated for their impact on teachers and students. The impact of these outreach efforts can be influenced by many things, but the instructional delivery method can affect how students are exposed to new topics or how confident teachers feel about incorporating new concepts into the classroom. A study was conducted with a series of university entomology outreach programs using insects as a vehicle for teaching environmental education. These programs were used to assess differences between three of the most common university-based outreach delivery methods (Scientist in the Classroom, Teacher Training Workshops, and Online Curriculum) for their effect on student interest and teacher self-efficacy. Surveys administered to 20 fifth grade classrooms found that the delivery method might not be as important as simply getting insects into activities. This study found that the lessons had a significant impact on student interest in environmental and entomological topics, regardless of treatment. All students found the lessons to be more interesting, valuable, and important over the course of the year. Treatment also did not influence teacher self-efficacy, as it remained high for all teachers. PMID:29473884

Background Restricted interests are a class of repetitive behavior in autism spectrum disorders (ASD) whose intensity and narrow focus often contribute to significant interference with daily functioning. While numerous neuroimaging studies have investigated executive circuits as putative neural substrates of repetitive behavior, recent work implicates affective neural circuits in restricted interests. We sought to explore the role of affective neural circuits and determine how restricted interests are distinguished from hobbies or interests in typical development. Methods We compared a group of children with ASD to a typically developing (TD) group of children with strong interests or hobbies, employing parent report, an operant behavioral task, and functional imaging with personalized stimuli based on individual interests. Results While performance on the operant task was similar between the two groups, parent report of intensity and interference of interests was significantly higher in the ASD group. Both the ASD and TD groups showed increased BOLD response in widespread affective neural regions to pictures of their own interest. When viewing pictures of other children's interests, the TD group showed a similar pattern, whereas BOLD response in the ASD group was much more limited. Increased BOLD response in the insula and anterior cingulate cortex distinguished the ASD from the TD group, and parent report of the intensity and interference with daily life of the child's restricted interest predicted insula response. Conclusions While affective neural network response and operant behavior are comparable in typical and restricted interests, the narrowness of focus that clinically distinguishes restricted interests in ASD is reflected in more interference in daily life and aberrantly enhanced insula and anterior cingulate response to individuals’ own interests in the ASD group. These results further support the involvement of affective neural networks in repetitive behaviors in ASD. PMID:24117668

This paper describes a methodology to perform chemical analyses in landfill areas by integrating multisource geomatic data. We used a top-down approach to identify Environmental Point of Interest (EPI) based on very high-resolution satellite data (Pleiades and WorldView 2) and on in situ thermal and photogrammetric surveys. Change detection techniques and geostatistical analysis supported the chemical survey, undertaken using an accumulation chamber and an RIIA, an unmanned ground vehicle developed by CNR IIA, equipped with a multiparameter sensor platform for environmental monitoring. Such an approach improves site characterization, identifying the key environmental points of interest where it is necessary to perform detailed chemical analyses. Copyright © 2017 Elsevier B.V.

Farmers' Preferences for PES Contracts to Adopt Silvopastoral Systems in Southern Ecuador, Revealed Through a Choice Experiment

Raes, Leander; Speelman, Stijn; Aguirre, Nikolay

2017-08-01

This study investigates farmers' preferences to participate in payment contracts to adopt silvopastoral systems in Ecuador. A choice experiment was used to elicit preferences between different contract attributes, including differing payment amounts and land management requirements. The research was carried out in the buffer zone of Podocarpus National Park in Southern Ecuador, an area where most land is dedicated to cattle husbandry. A choice experiment was conducted to measure farmers' interest in different types of contracts. Based on existing incentive programs, contract choices varied with respect to the type of silvopastoral system, extra land-use requirements, payment levels and contract duration. In addition, contracts differed with regards to access by cattle to streams. Although the farmers did not show strong preferences for every contract attribute, the majority of farmers in the area showed interest in the proposed contracts. A latent class model identified three classes of respondents, based on their preferences for different contracts attributes or the "business as usual" option. The results suggest that farmland area, agricultural income, and landowners' perceptions of environmental problems provide a partial explanation for the heterogeneity observed in the choices for specific contracts. Participation might increase if contracts were targeted at specific groups of farmers, such as those identified through our latent class model. Offering flexible contracts with varying additional requirements within the same scheme, involving farmers from the start in payments for environmental services design, and combining payments for environmental services with integrated conservation and development projects may be a better way to convince more farmers to adopt silvopastoral systems.

Plants are categorized in three groups concerning their uptake of heavy metals: indicator, excluder, and hyperaccumulator plants, which we explain in this chapter, the former two groups briefly and the hyperaccumulators in detail. The ecological role of hyperaccumulation, for example, the prevention of herbivore attacks and a possible substitution of Zn by Cd in an essential enzyme, is discussed. As the mechanisms of cadmium hyperaccumulation are a very interesting and challenging topic and many aspects are studied worldwide, we provide a broad overview over compartmentation strategies, expression and function of metal transporting proteins and the role of ligands for uptake, transport, and storage of cadmium. Hyperaccumulators are not without reason a topic of great interest, they can be used biotechnologically for two main purposes which we discuss here for Cd: phytoremediation, dealing with the cleaning of anthropogenically contaminated soils as well as phytomining, i.e., the use of plants for commercial metal extraction. Finally, the outlook deals with topics for future research in the fields of biochemistry/biophysics, molecular biology, and biotechnology. We discuss which knowledge is still missing to fully understand Cd hyperaccumulation by plants and to use that phenomenon even more successfully for both environmental and economical purposes.

Insulin deprivation induces PP2A inhibition and tau hyperphosphorylation in hTau mice, a model of Alzheimer’s disease-like tau pathology

Abnormally hyperphosphorylated tau aggregated as intraneuronal neurofibrillary tangles is one of the two neuropathological hallmarks of Alzheimer’s disease (AD). The majority of AD cases are sporadic with numerous environmental, biological and genetic risks factors. Interestingly, insulin dysfunction and hyperglycaemia are both risk factors for sporadic AD. However, how hyperglycaemia and insulin dysfunction affect tau pathology, is not well understood. In this study, we examined the effects of insulin deficiency on tau pathology in transgenic hTau mice by injecting different doses of streptozotocin (STZ), a toxin that destroys insulin-producing cells in the pancreas. One high dose of STZ resulted in marked diabetes, and five low doses led to a milder diabetes. Both groups exhibited brain tau hyperphosphorylation but no increased aggregation. Tau hyperphosphorylation correlated with inhibition of Protein Phosphatase 2A (PP2A), the main tau phosphatase. Interestingly, insulin injection 30 minutes before sacrifice partially restored tau phosphorylation to control levels in both STZ-injected groups. Our results confirm a link between insulin homeostasis and tau phosphorylation, which could explain, at least in part, a higher incidence of AD in diabetic patients. PMID:28402338

Structuring agency: examining healthcare management in the USA and Australia using organizational theory.

Payne, Julianne; Leiter, Jeffrey

Since the 1970s, the healthcare industry has undergone significant changes. Using neo-institutional and resource dependency theories, the purpose of this paper is to explore how managers perceive constraint and enact agency amidst these historic challenges--perhaps most significantly, declining funding and increasing regulation. The data come from ten interviews with healthcare managers, spanning for-profit, non-profit, and government legal forms and hospital and nursing home sub-industries in both Queensland, Australia and North Carolina, USA. The authors look for patterns across the interviews. The paper shows that governments and umbrella "parent" organizations force managers to adhere to institutional expectations in exchange for resource investment. Managers navigate these environmental obstacles using a shared business-minded approach and competitive differentiation. Yet various interest groups--including front-line workers, physicians, and patients--challenge this paradigm, as they demand a focus on quality of care. Managers' efforts are likewise curbed by the very resource and institutional pressures they resist. The authors understand changes in the healthcare industry as resulting from an increasingly powerful managerial logic, at odds with traditional professional and societal values. Interest groups are best positioned to challenge this logic.

Gene expression variation is a phenotypic trait of particular interest as it represents the initial link between genotype and other phenotypes. Analyzing how such variation apportions among and within groups allows for the evaluation of how genetic and environmental factors influence such traits. It also provides opportunities to identify genes and pathways that may have been influenced by non-neutral processes. Here we use a population genetics framework and next generation sequencing to evaluate how gene expression variation is apportioned among four human groups in a natural biological tissue, the placenta. We estimate that on average, 33.2%, 58.9%, and 7.8% of the placental transcriptome is explained by variation within individuals, among individuals, and among human groups, respectively. Additionally, when technical and biological traits are included in models of gene expression they each account for roughly 2% of total gene expression variation. Notably, the variation that is significantly different among groups is enriched in biological pathways associated with immune response, cell signaling, and metabolism. Many biological traits demonstrate correlated changes in expression in numerous pathways of potential interest to clinicians and evolutionary biologists. Finally, we estimate that the majority of the human placental transcriptome exhibits expression profiles consistent with neutrality; the remainder are consistent with stabilizing selection, directional selection, or diversifying selection. We apportion placental gene expression variation into individual, population, and biological trait factors and identify how each influence the transcriptome. Additionally, we advance methods to associate expression profiles with different forms of selection.

Burkholderia species play an important ecological role related to xenobiosis, the promotion of plant growth, the biocontrol of agricultural diseases, and symbiotic and non-symbiotic biological nitrogen fixation. Here, we highlight our study as providing the first complete genome of a symbiotic strain of B. phenoliruptrix, BR3459a (=CLA1), which was originally isolated in Brazil from nodules of Mimosa flocculosa and is effective in fixing nitrogen in association with this leguminous species. Genomic comparisons with other pathogenic and non-pathogenic Burkholderia strains grouped B. phenoliruptrix BR3459a with plant-associated beneficial and environmental species, although it shares a high percentage of its gene repertoire with species of the B. cepacia complex (Bcc) and "pseudomallei" group. The genomic analyses showed that the bce genes involved in exopolysaccharide production are clustered together in the same genomic region, constituting part of the Group III cluster of non-pathogenic bacteria. Regarding environmental stresses, we highlight genes that might be relevant in responses to osmotic, heat, cold and general stresses. Furthermore, a number of particularly interesting genes involved in the machinery of the T1SS, T2SS, T3SS, T4ASS and T6SS secretion systems were identified. The xenobiotic properties of strain BR3459a were also investigated, and some enzymes involved in the degradation of styrene, nitrotoluene, dioxin, chlorocyclohexane, chlorobenzene and caprolactam were identified. The genomic analyses also revealed a large number of antibiotic-related genes, the most important of which were correlated with streptomycin and novobiocin. The symbiotic plasmid showed high sequence identity with the symbiotic plasmid of B. phymatum. Additionally, comparative analysis of 545 housekeeping genes among pathogenic and non-pathogenic Burkholderia species strongly supports the definition of a new genus for the second branch, which would include BR3459a. The analyses of B. phenoliruptrix BR3459a showed key property of fixing nitrogen that together with genes for high tolerance to environmental stresses might explain a successful strategy of symbiosis in the tropics. The strain also harbours interesting sets of genes with biotechnological potential. However, the resemblance of certain genes to those of pathogenic Burkholderia raise concerns about large-scale applications in agriculture or for bioremediation.

Can the Discrepancy between Locally and Globally Derived Neutral Hydrogen Mass Functions be Explained by a Varying Value of M ⋆?

NASA Astrophysics Data System (ADS)

Minchin, Robert F.

2017-09-01

I investigate whether it is possible to reconcile the recent Arecibo Legacy Fast Arecibo L-band Feed Array (ALFALFA) observation that the neutral hydrogen mass function (HIMF) across different galactic densities has the same, non-flat, faint-end slope, with observations of isolated galaxies and many galaxy groups that show their HIMFs to have flat faint-end slopes. I find that a fairly simple model in which the position of the knee in the mass function of each individual group is allowed to vary is able to account for both of these observations. If this model reflects reality, the ALFALFA results point to an interesting “conspiracy” whereby the differing group HIMFs always sum up to form global HIMFs with the same faint-end slope in different environments. More generally, this result implies that global environmental HIMFs do not necessarily reflect the HIMFs in individual groups belonging to that environment and cannot be used to directly measure variations in group-specific HIMFs with environment.

This mini-monograph was developed to highlight the experiences of the National Institute of Environmental Health Sciences (NIEHS)/U.S. Environmental Protection Agency (EPA) Centers for Children's Environmental Health and Disease Prevention Research, focusing particularly on several areas of interest for the National Children's Study. These include general methodologic issues for conducting longitudinal birth cohort studies and community-based participatory research and for measuring air pollution exposures, pesticide exposures, asthma, and neurobehavioral toxicity. Rather than a detailed description of the studies in each of the centers, this series of articles is intended to provide information on the practicalities of conducting such intensive studies and the lessons learned. This explication of lessons learned provides an outstanding opportunity for the planners of the National Children's Study to draw on past experiences that provide information on what has and has not worked when studying diverse multiracial and multiethnic groups of children with unique urban and rural exposures. The Children's Centers have addressed and overcome many hurdles in their efforts to understand the link between environmental exposures and health outcomes as well as interactions between exposures and a variety of social and cultural factors. Some of the major lessons learned include the critical importance of long-term studies for assessing the full range of developmental consequences of environmental exposures, recognition of the unique challenges presented at different life stages for both outcome and exposure measurement, and the importance of ethical issues that must be dealt with in a changing medical and legal environment. It is hoped that these articles will be of value to others who are embarking on studies of children's environmental health.

Many stakeholders in the utilizing of environmental services and natural attraction of Tuk Semuncar Utilization Zone needs to get the attention of the Gunung Merbabu National Park Officer. The existence of natural resources has an important role for the life of the community, making the complexity of the relationship between various parties who have interests in natural resource management. The existence of stakeholders and their interests should receive attention and be considered to be accommodated as an effort to prevent the occurrence of losses to the conservation area of Gunung Merbabu National Park. Every stakeholder's interest can have a positive and negative impact on other stakeholders. Stakeholder analysis can help in understanding the conflict on the utilizing of environmental services and natural attraction that is happening, as well as input strategy in involving stakeholders for the achievement of goals.

Global patterns of development suggest that as more projects are initiated, business will need to find acceptable measures to conserve biodiversity. The application of environmental offsets allows firms to combine their economic interests with the environment and society. This article presents the results of a multi-stakeholder analysis related to the design of offsets principles, policies, and regulatory processes, using a large infrastructure projects context. The results indicate that business was primarily interested in using direct offsets and other compensatory measures, known internationally as indirect offsets, to acquit their environmental management obligations. In contrast, the environmental sector argued that highly principled and scientifically robust offsets programs should be implemented and maintained for enduring environmental protection. Stakeholder consensus stressed the importance of offsets registers with commensurate monitoring and enforcement. Our findings provide instructive insights into the countervailing views of offsets policy stakeholders. Copyright © 2016 Elsevier Ltd. All rights reserved.

A context based approach using Green Chemistry/Bio-remediation principles to enhance interest and learning of organic chemistry in a high school AP chemistry classroom

Miller, Tricia

The ability of our planet to sustain life and heal itself is not as predictable as it used to be. Our need for educated future scientists who know what our planet needs, and can passionately apply that knowledge to find solutions should be at the heart of science education today. This study of learning organic chemistry through the lens of the environmental problem "What should be done with our food scraps?" explores student interest, and mastery of certain concepts in organic chemistry. This Green Chemistry/ Bio-remediation context-based teaching approach utilizes the Nature MillRTM, which is an indoor food waste composting machine, to learn about organic chemistry, and how this relates to landfill reduction possibilities, and resource production. During this unit students collected food waste from their cafeteria, and used the Nature MillRTM to convert food waste into compost. The use of these hands on activities, and group discussions in a context-based environment enhanced their interest in organic chemistry, and paper chromatography. According to a one-tailed paired T-test, the result show that this context-based approach is a significant way to increase both student interest and mastery of the content.

The US contains numerous hazardous waste sites. Many sites are on private land near operating units of various companies. An effort is being made to determine the conditions under which such sites can be remediated voluntarily. The objective of the project will be to first assess the interest and willingness of industry in the Kanawha River Valley, WV to participate in discussions that would lead toward voluntary cleanup activities. The second will be to implement the activities agreed upon by the interested parties. The project will first involve individual discussions with the industrial, government, and other organized groups in themore » area. These discussions will help determine the feasibility of organizing voluntary efforts. If the discussions indicate that conditions may be favorable for developing individual or group voluntary cleanup projects, a working group will be convened to establish the environmental goals of the project as well as the technical approach for achieving those goals. The projects for the 1996 WVU Cooperative Agreement are categorized into three task focus areas: Task 1.0 Contaminant Plume Containment and Remediation, Task 2.0 Cross Cutting Innovative Technologies, and Task 3.0 Small Business Support Program. Summaries of the accomplishments for the subtasks reporting under these categories during the third quarter, 1 July 96 through 30 September 96, are presented.« less

Self-organizing team formation for target observation

NASA Astrophysics Data System (ADS)

Bowyer, Richard S.; Bogner, Robert E.

2001-08-01

Target observation is a problem where the application of multiple sensors can improve the probability of detection and observation of the target. Team formation is one method by which seemingly unsophisticated heterogeneous sensors may be organized to achieve a coordinated observation system. The sensors, which we shall refer to as agents, are situated in an area of interest with the goal of observing a moving target. We apply a team approach to this problem, which combines the strengths of individual agents into a cohesive entity - the team. In autonomous systems, the mechanisms that underlie the formation of a team are of interest. Teams may be formed by various mechanisms, which include an externally imposed grouping of agents, or an internally, self-organized (SO) grouping of agents. Internally motivated mechanisms are particularly challenging, but offer the benefit of being unsupervised, an important quality for groups of autonomous cooperating machines. This is the focus of our research. By studying natural systems such as colonies of ants, we obtain insight into these mechanisms of self organization. We propose that the team is an expression of a distributed agent-self, and that a particular realization of the agent-self exists, whilst the environmental conditions are conducive to that existence. We describe an algorithms for agent team formation that is inspired by the self-organizing behavior of ants, and describe simulation results for team formation amongst a lattice of networked sensors.

The recent increase in the incidence of deformities among natural frog populations has raised concern about the state of the environment and the possible impact of unidentified causative agents on the health of wildlife and human populations. An open workshop on Strategies for Assessing the Implications of Malformed Frogs for Environmental Health was convened on 4-5 December 1997 at the National Institute of Environmental Health Sciences in Research Triangle Park, North Carolina. The purpose of the workshop was to share information among a multidisciplinary group with scientific interest and responsibility for human and environmental health at the federal and state level. Discussions highlighted possible causes and recent findings directly related to frog deformities and provided insight into problems and strategies applicable to continuing investigation in several areas. Possible causes of the deformities were evaluated in terms of diagnostics performed on field amphibians, biologic mechanisms that can lead to the types of malformations observed, and parallel laboratory and field studies. Hydrogeochemistry must be more integrated into environmental toxicology because of the pivotal role of the aquatic environment and the importance of fates and transport relative to any potential exposure. There is no indication of whether there may be a human health factor associated with the deformities. However, the possibility that causal agents may be waterborne indicates a need to identify the relevant factors and establish the relationship between environmental and human health in terms of hazard assessment.

The environmental sciences/studies movement, with more than 1000 programs at colleges and universities in the United States and Canada, is unified by a common interest-ameliorating environmental problems through empirical enquiry and analytic judgment. Unfortunately, environmental programs have struggled in their efforts to integrate knowledge across disciplines and educate students to become sound problem solvers and leaders. We examine the environmental program movement as a policy problem, looking at overall goals, mapping trends in relation to those goals, identifying the underlying factors contributing to trends, and projecting the future. We argue that despite its shared common interest, the environmental program movement is disparate and fragmented by goal ambiguity, positivistic disciplinary approaches, and poorly rationalized curricula, pedagogies, and educational philosophies. We discuss these challenges and the nature of the changes that are needed in order to overcome them. In a subsequent article (Part 2) we propose specific strategies for improvement. ?? 2011 Springer Science+Business Media, LLC.

Dose Comparisons for a Site-specific Representative Person Using the Age-dependent Dose Coefficients in CAP88-PC Version 4.

PubMed

Stagich, Brooke H; Moore, Kelsey R; Newton, Joseph R; Dixon, Kenneth L; Jannik, G Timothy

2017-04-01

Most U.S. Department of Energy (DOE) facilities with radiological airborne releases use the U.S. Environmental Protection Agency's (EPA) environmental dosimetry code CAP88-PC to demonstrate compliance with regulations in 40CFR61, subpart H [National Emission Standards for Hazardous Air Pollutants: Radiological (NESHAP)]. In 2015, EPA released Version 4 of CAP88-PC, which included significant modifications that improved usability and age-dependent dose coefficients and usage factors for six age groups (infant, 1 y, 5 y, 10 y, 15 y, and adult). However, EPA has not yet provided specific guidance on how to use these age-dependent factors. For demonstrating compliance with DOE public dose regulations, the Savannah River Site (SRS) recently changed from using the maximally exposed individual (MEI) concept (adult male) to the representative person concept (age- and gender-averaged reference person). In this study, dose comparisons are provided between the MEI and a SRS-specific representative person using the age-specific dose coefficients and usage factors in CAP88-PC V.4. Dose comparisons also are provided for each of the six age groups using five radionuclides of interest at SRS (tritium oxide, Cs, Sr, Pu, and I). In general, the total effective dose increases about 11% for the representative person as compared to the current NESHAP MEI because of the inclusion of the more radiosensitive age groups.

Exploring differences in stakeholders' perceptions of illegal bird trapping in Cyprus.

PubMed

Jenkins, Heather M; Mammides, Christos; Keane, Aidan

2017-11-28

Cyprus is recognised as a hotspot for illegal bird trapping in the Mediterranean basin. A consumer demand for the Eurasian blackcap (Sylvia atricapilla) is driving the use of non-selective trapping methods, resulting in the indiscriminate killing of millions of migratory birds. Efforts to tackle the issue have so far been characterised mostly by a top-down approach, focusing on legislation and enforcement. However, trapping levels are not decreasing and conflict between stakeholder groups is intensifying. To understand why efforts to stop illegal bird trapping have not been effective, we used semi-structured interviews to interview 18 local bird trappers and nine representatives from the pertinent environmental non-governmental organisations (NGOs) and the governmental agencies responsible for enforcing the legislation. We found distinct differences between the views of the local trapping community and the environmental NGOs, particularly on why trapping is occurring and its impact on the avifauna. This disparity has contributed to misrepresentations of both sides and a high degree of conflict, which is potentially proving counterproductive to conservation interventions. In addition, it appears that trappers are a heterogeneous group, likely driven by various motivations besides profit. We argue that stakeholders interested in reducing illegal bird trapping need to develop anti-poaching strategies that aim at minimising the disparity in the views, and subsequently the conflict, acknowledging also that trappers are not a homogenous group, as often treated.

The use of multicomponent statistical analysis in hydrogeological environmental research.

Lambrakis, Nicolaos; Antonakos, Andreas; Panagopoulos, George

2004-04-01

The present article examines the possibilities of investigating NO(3)(-) spread in aquifers by applying multicomponent statistical methods (factor, cluster and discriminant analysis) on hydrogeological, hydrochemical, and environmental parameters. A 4-R-Mode factor model determined from the analysis showed its useful role in investigating hydrogeological parameters affecting NO(3)(-) concentration, such as its dilution by upcoming groundwater of the recharge areas. The relationship between NO(3)(-) concentration and agricultural activities can be determined sufficiently by the first factor which relies on NO(3)(-) and SO(4)(2-) of the same origin-that of agricultural fertilizers. The other three factors of R-Mode analysis are not connected directly to the NO(3)(-) problem. They do however, by extracting the role of the unsaturated zone, show an interesting relationship between organic matter content, thickness and saturated hydraulic conductivity. The application of Hirerarchical Cluster Analysis, based on all possible combinations of classification method, showed two main groups of samples. The first group comprises samples from the edges and the second from the central part of the study area. By the application of Discriminant Analysis it was shown that NO(3)(-) and SO(4)(2-) ions are the most significant variables in the discriminant function. Therefore, the first group is considered to comprise all samples from areas not influenced by fertilizers lying on the edges of contaminating activities such as crop cultivation, while the second comprises all the other samples.

Oil shale development and its environmental considerations

USGS Publications Warehouse

Stone, R.T.; Johnson, H.; Decora, A.

1974-01-01

The petroleum shortage recently experienced by many nations throughout the world has created an intense interest in obtaining new and supplemental energy sources. In the United States, this interest has been centered on oil shale. Any major action by the federal government having significant environmental effects requires compliance with the National Environmental Policy Act of 1969 (NEPA). Since most oil shale is found on federal lands, and since its development involves significant environmental impacts, leasing oil shale lands to private interests must be in compliance with NEPA. For oil shale, program planning began at approximately the same time that NEPA was signed into law. By structuring the program to permit a resource and technological inventory by industry and the federal agencies, the Department of the Interior was able simultaneously to conduct the environmental assessments required by the act. This required: 1. Clearly defined program objections; 2. An organization which could integrate public policy with diverse scientific disciplines and environmental concerns; and 3. Flexible decisionmaking to adjust to policy changes as well as to evolving interpretations on EPA as clarified by court decisions. This paper outlines the program, the organization structure that was created for this specific task, and the environmental concerns which were investigated. The success of the program has been demonstrated by meeting the requirements of NEPA, without court challenge, and by industry's acceptance of a leasing program that included the most stringent environmental protection provisions ever required. The need for energy development has spurred the acceptance of the program. However, by its awareness and willingness to meet the environmental challenges of the future, industry has shown a reasonable understanding of its commitments. The pros and cons of development were publicly considered in hearings and analyzed in the final environmental statement. This action aided greatly in preventing legal challenges. The prototype oil shale program is now under way and this new energy source, developed with strict environmental safeguards, may soon be available to our nation.

Testing the Value of Information of Climate Change Indicators that use Earth Observations

Indicators are usually thought of as measurements or calculations that represent important features of the status, trend, or performance of a system of interest (e.g. the economy, agriculture, air quality). They are often used for the most practical of reasons - one cannot measure everything important about systems of interest, so there is a practical need to identify major features that can be reported periodically and used to guide both research and decisions (National Research Council (NRC). 2000. Ecological Indicators for the Nation. National Academy Press. Washington, DC). The use of indicators to track the status and trends of many features of environmental or economic performance, quality of life, and a host of other social concerns is embedded in the fabric of our everyday lives. Businesses, governments, and consumers regularly use the common economic indices - e.g. the unemployment index or consumer price index - as guides for decision-making on investments and hiring. There is an analogous demand for indicators of environmental conditions and performance - everything from agricultural yields to air and water quality to weather and climate - that are currently less publicly visible than the common economic indicators, but that can have critically important uses in such areas as natural resource management, improvement of environmental quality, emergency planning, and infrastructure development. A number of these environmental indicators, be it physical or ecological, use a range of data sources including earth observations. Despite the extensive development and use of indicators, there is little testing of these indicators to assure that they indeed provide the assumed positive information benefit. This is particularly concerning because if these indicators are systematically misunderstood by the intended audience or a sub-group of that audience, such individuals could make decisions that are consistent with their incorrect understanding of the indicator. Such a result would mean that the indicator has a negative value of information. Granted the value of information depends on the intended audience(s), with some groups being able to understand and want more technically sophisticated and detailed information presented as an indicator. However, if the goal of an indicator is to provide information to a wide range of groups, it is essential to assure that these groups have a correct understanding of the indicator, its assumptions, and the ability to use the indicator (as presented or modified) for decision-making contexts. In this talk, I will present the preliminary results of a study that is testing the value of information of a range of climate change indicators, and I will focus on indicators that use earth observations. Such results contribute to a richer understanding of the value of information of indicators, and can shape the development of both individual indicators and systems of indicators, such as the development of the indicator system for the U.S. Global Change Research Program, National Climate Assessment.

Enhancing situational interest in pediatrics.

Individual interest, something that persists regardless of the situation, and situational interest, finding personal value in an educational context, have not been studied in medical student education. To determine if individualized case discussions enhance interest in pediatric medicine. During the 2008/2009 academic year, 88 clerkship students participated in clinical case discussions. At orientation, students completed an Interest in Pediatrics (IIP) questionnaire, responding 1 = strongly disagree to 5 = strongly agree. Intervention and control groups were randomly assigned. The intervention group personalized cases to students' medical specialty interests. The control group discussed the case presentation. Groups met twice during the 8-week clerkships, completing a post-IIP at the end of the clerkship. Intervention group interest increased from pre-IIP, mean = 3.64, to post-IIP, mean = 4.22 (z = -2.994, p < 0.05, r = -0.44). On post-IIP, application of pediatric medicine increased for both groups; the intervention group was most significant from pre-IIP, mean = 1.09, to post-IIP, mean = 4.33 (z = -6.038, p < 0.05, r = -0.88). Enhanced interest in pediatrics from the intervention group indicates that creating a learning environment personally relevant to students' careers facilitates interest to learn.

Restricted interests are a class of repetitive behavior in autism spectrum disorders (ASD) whose intensity and narrow focus often contribute to significant interference with daily functioning. While numerous neuroimaging studies have investigated executive circuits as putative neural substrates of repetitive behavior, recent work implicates affective neural circuits in restricted interests. We sought to explore the role of affective neural circuits and determine how restricted interests are distinguished from hobbies or interests in typical development. We compared a group of children with ASD to a typically developing (TD) group of children with strong interests or hobbies, employing parent report, an operant behavioral task, and functional imaging with personalized stimuli based on individual interests. While performance on the operant task was similar between the two groups, parent report of intensity and interference of interests was significantly higher in the ASD group. Both the ASD and TD groups showed increased BOLD response in widespread affective neural regions to the pictures of their own interest. When viewing pictures of other children's interests, the TD group showed a similar pattern, whereas BOLD response in the ASD group was much more limited. Increased BOLD response in the insula and anterior cingulate cortex distinguished the ASD from the TD group, and parent report of the intensity and interference with daily life of the child's restricted interest predicted insula response. While affective neural network response and operant behavior are comparable in typical and restricted interests, the narrowness of focus that clinically distinguishes restricted interests in ASD is reflected in more interference in daily life and aberrantly enhanced insula and anterior cingulate response to individuals' own interests in the ASD group. These results further support the involvement of affective neural networks in repetitive behaviors in ASD. © 2013 The Authors.

Dissecting complex interactions between species and their environments has long been a research hot spot in the fields of ecology and evolutionary biology. The well-recognized Darwinian evolution has well-explained long-term adaptation scenarios; however, "rapid" processes of biological responses to environmental changes remain largely unexplored, particularly molecular mechanisms such as DNA methylation that have recently been proposed to play crucial roles in rapid environmental adaptation. Invasive species, which have capacities to successfully survive rapidly changing environments during biological invasions, provide great opportunities to study molecular mechanisms of rapid environmental adaptation. Here, we used the methylation-sensitive amplified polymorphism (MSAP) technique in an invasive model ascidian, Ciona savignyi, to investigate how species interact with rapidly changing environments at the whole-genome level. We detected quite rapid DNA methylation response: significant changes of DNA methylation frequency and epigenetic differentiation between treatment and control groups occurred only after 1 hr of high-temperature exposure or after 3 hr of low-salinity challenge. In addition, we detected time-dependent hemimethylation changes and increased intragroup epigenetic divergence induced by environmental stresses. Interestingly, we found evidence of DNA methylation resilience, as most stress-induced DNA methylation variation maintained shortly (~48 hr) and quickly returned back to the control levels. Our findings clearly showed that invasive species could rapidly respond to acute environmental changes through DNA methylation modifications, and rapid environmental changes left significant epigenetic signatures at the whole-genome level. All these results provide fundamental background to deeply investigate the contribution of DNA methylation mechanisms to rapid contemporary environmental adaptation. © 2017 John Wiley & Sons Ltd.

In the article was presented results of international researches about environmental consciousness. The project was realized in 2015. The main purpose of this article is to describe the level of environmental knowledge, values and attitudes among university students from Central Eastern Europe. In introduction of article was defined concept of environmental awareness. The research problem is question: What are differences in the state of environmental awareness between respondents living in the Poland, Slovakia and Ukraine? In the first part text was presented methodology of the conducted research. The second part of the article concerns the analysis of the collected data. On the basis of the conducted research it can maintain that the students of Central and Eastern Europe generally declared interest the state of the environment. The overall outcome of the research leads to the conclusion that the highest proportion of the respondents who declared interest in the environmental protection came from Slovakia. The fact that in their opinion it should care about the environment more than the students from Poland and Ukraine may result from the higher level of the environmental awareness.

Perfluorocarboxylic acids (PFCAs) are among the diverse groups of compounds characterized as persistent organic pollutants. They are toxic, resistant to environmental degradation, and adversely impact human and environmental health. PFCAs with four or fewer carbons, short-chain PFCAs (scPFCAs), are of particular interest because of their increasing levels in the environment, toxicity to plants, and potential for accumulation in some aquatic ecosystems, making them an emerging environmental concern. A minor source of scPFCAs to the Arctic has been shown to be atmospheric transformation of fluoropolymer precursors, followed by deposition. Additional potential sources of scPFCAs to the Arctic are chlorofluorocarbon (CFC)-replacement compounds. Through analysis of an ice core from the Canadian High Arctic, we show that Montreal Protocol-mandated introduction of CFC-replacement compounds for the heat-transfer industry has led to increasing inputs of these scPFCAs to the remote environment. Flux measurements for scPFCAs as a class of contaminants have only been reported in a couple studies to date. Here, we provide the first multi-decadal temporal record of scPFCA deposition, demonstrating a dramatic increase in deposition resulting from emission of CFC-replacements. These results bring to the forefront a need for a holistic approach to environmental risk assessment that considers impacts of replacement substances and degradation products.

Adult wheel access interaction with activity and boldness personality in Siberian dwarf hamsters (Phodopus sungorus).

Individual animal personalities interact with environmental conditions to generate differences in behavior, a phenomenon of growing interest for understanding the effects of environmental enrichment on captive animals. Wheels are common environmental enrichment for laboratory rodents, but studies conflict on how this influences behavior, and interaction of wheels with individual personalities has rarely been examined. We examined whether wheel access altered personality profiles in adult Siberian dwarf hamsters. We assayed animals in a tunnel maze twice for baseline personality, then again at two and at seven weeks after the experimental group was provisioned with wheels in their home cages. Linear mixed model selection was used to assess changes in behavior over time and across environmental gradient of wheel exposure. While animals showed consistent inter-individual differences in activity, activity personality did not change upon exposure to a wheel. Boldness also varies among individuals, and there is evidence for female boldness scores converging after wheel exposure, that is, opposite shifts in behavior by high and low boldness individuals, although sample size is too small for the mixed model results to be robust. In general, Siberian dwarf hamsters appear to show low behavioral plasticity, particularly in general activity, in response to running wheels. Copyright © 2017 Elsevier B.V. All rights reserved.

as response to seasonal variability

Badano, Ernesto I; Labra, Fabio A; Martínez-Pérez, Cecilia G; Vergara, Carlos H

2016-03-01

Ecologists have been largely interested in the description and understanding of the power scaling relationships between body size and abundance of organisms. Many studies have focused on estimating the exponents of these functions across taxonomic groups and spatial scales, to draw inferences about the processes underlying this pattern. The exponents of these functions usually approximate -3/4 at geographical scales, but they deviate from this value when smaller spatial extensions are considered. This has led to propose that body size-abundance relationships at small spatial scales may reflect the impact of environmental changes. This study tests this hypothesis by examining body size spectra of benthic shrimps (Decapoda: Caridea) and snails (Gastropoda) in the Tamiahua lagoon, a brackish body water located in the Eastern coast of Mexico. We mea- sured water quality parameters (dissolved oxygen, salinity, pH, water temperature, sediment organic matter and chemical oxygen demand) and sampled benthic macrofauna during three different climatic conditions of the year (cold, dry and rainy season). Given the small size of most individuals in the benthic macrofaunal samples, we used body volume, instead of weight, to estimate their body size. Body size-abundance relationships of both taxonomic groups were described by tabulating data from each season into base-2 logarithmic body size bins. In both taxonomic groups, observed frequencies per body size class in each season were standardized to yield densities (i.e., individuals/m(3)). Nonlinear regression analyses were separately performed for each taxonomic group at each season to assess whether body size spectra followed power scaling functions. Additionally, for each taxonomic group, multiple regression analyses were used to determine whether these relationships varied among seasons. Our results indicated that, while body size-abundance relationships in both taxonomic groups followed power functions, the parameters defining the shape of these relationships varied among seasons. These variations in the parameters of the body size-abundance relationships seems to be related to changes in the abundance of individuals within the different body size classes, which seems to follow the seasonal changes that occur in the environmental conditions of the lagoon. Thus, we propose that these body size-abundance relation- ships are influenced by the frequency and intensity of environmental changes affecting this ecosystem.

ENVIRONMENTAL BENIGN MITIGATION OF MICROBIOLOGICALLY INFLUENCED CORROSION (MIC)

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

J.R. Paterek; G. Husmillo; V. Trbovic

The overall program objective is to develop and evaluate environmental benign agents or products that are effective in the prevention, inhibition, and mitigation of microbially influenced corrosion (MIC) in the internal surfaces of metallic natural gas pipelines. The goal is one or more environmental benign, a.k.a. ''green'' products that can be applied to maintain the structure and dependability of the natural gas infrastructure. The technical approach for this quarter were isolation and cultivation of MIC-causing microorganisms from corroded pipeline samples, optimizing parameters in the laboratory-scale corrosion test loop system and testing the effective concentrations of Capsicum sp. extracts to verifymore » the extent of corrosion on metal coupons by batch culture method. A total of 22 strains from the group of heterotrophic, acid producing, denitrifying and sulfate reducing bacteria were isolated from the gas pipeline samples obtained from Northern Indiana Public Service Company in Trenton, Indiana. They were purified and will be sent out for identification. Bacterial strains of interest were used in antimicrobial screenings and test loop experiments. Parameters for the laboratory-scale test loop system such as gas and culture medium flow rate; temperature; inoculation period; and length of incubation were established. Batch culture corrosion study against Desulfovibrio vulgaris showed that one (S{sub 1}M) out of the four Capsicum sp. extracts tested was effective in controlling the corrosion rate in metal coupons by 33.33% when compared to the untreated group.« less

Transparent stakeholder engagement in practice: Lessons learned from applying comprehensive environmental assessment to research planning for nanomaterials.

Powers, Christina; Hendren, Christine; Wang, Amy; Davis, J Michael

2014-10-01

As efforts to develop new applications of engineered nanoscale materials (ENMs) continue to grow, so too has interest in the environmental, health, and safety (EHS) implications of these materials. However, thorough evaluation and interpretation of such implications could require substantial resources (e.g., estimated as >$120 million per year in federal funding 2013-2017). A structured, strategic approach for transparently planning research would support improved linkages between ENM research and risk assessments, and thereby enhance the utility of financial and other resources for EHS studies of ENMs. For this reason, we applied Comprehensive Environmental Assessment (CEA) as an approach to provide transparent input into research planning for 2 types of ENMs: nanoscale titanium dioxide and nanoscale silver. For each of these CEA applications, we employed a collective judgment method known as Nominal Group Technique (NGT) in 2 workshops sponsored by the US Environmental Protection Agency (USEPA). The objective of this paper is to present the outcomes of these CEA applications in the context of how our methodology can inform future efforts to identify collective goals in science (e.g., research priorities) through structured decision support approaches. Outcomes include clear lists of research priorities for each ENM developed through transparently engaging stakeholders having diverse technical and sector perspectives. In addition, we identified several procedural aspects that could be refined, including emphasizing breakout group interactions, identifying broad information priorities before more detailed research questions, and using rating rather than ranking prioritization methods. Beyond the research directions identified for specific ENMs, lessons learned about engaging stakeholders in research planning are expected to inform future research planning efforts for ENMs and other emerging materials across the scientific community. © 2014 SETAC.

There is a growing literature on the resolution of natural resources conflicts. Much of it is practical, focusing on guidelines for hands-on negotiation. This literature can be a guide in water conflicts. This is especially true for negotiations over new environmental values such as instream flow. The concepts of competitive, cooperative, and integrative styles of conflict resolution are applied to three cases of water resource bargaining. Lessons for the effective use of these ideas include: break a large number of parties into small working groups, approach value differences in small steps, be cautious in the presence of an attentive public, keeps decisions at the local level, and understand the opponent's interests.

Mapping approaches offer great potential for community-based participatory researchers interested in displaying youth perceptions and advocating for change. We describe a multi-layered approach for gaining local knowledge of neighborhood environments that engages youth as co-researchers and active knowledge producers. By integrating geographic information systems (GIS) with environmental audits, an interactive focus group, and sketch mapping, the approach provides a place-based understanding of physical activity resources from the situated experience of youth. Youth report safety and a lack of recreational resources as inhibiting physical activity. Maps reflecting youth perceptions aid policy-makers in making place-based improvements for youth neighborhood environments. PMID:25423245

American College of Occupational and Environmental Medicine (ACOEM): a professional association in service to industry.

PubMed

LaDou, Joseph; Teitelbaum, Daniel T; Egilman, David S; Frank, Arthur L; Kramer, Sharon N; Huff, James

2007-01-01

The American College of Occupational and Environmental Medicine (ACOEM) is a professional association that represents the interests of its company-employed physician members. Fifty years ago the ACOEM began to assert itself in the legislative arena as an advocate of limited regulation and enforcement of occupational health and safety standards and laws, and environmental protection. Today the ACOEM provides a legitimizing professional association for company doctors, and continues to provide a vehicle to advance the agendas of their corporate sponsors. Company doctors in ACOEM recently blocked attempts to have the organization take a stand on global warming. Company doctors employed by the petrochemical industry even blocked the ACOEM from taking a position on particulate air pollution. Industry money and influence pervade every aspect of occupational and environmental medicine. The controlling influence of industry over the ACOEM physicians should cease. The conflict of interests inherent in the practice of occupational and environmental medicine is not resolved by the ineffectual efforts of the ACOEM to establish a pretentious code of conduct. The conflicted interests within the ACOEM have become too deeply embedded to be resolved by merely a self-governing code of conduct. The specialty practice of occupational and environmental medicine has the opportunity and obligation to join the public health movement. If it does, the ACOEM will have no further purpose as it exists, and specialists in occupational and environmental medicine will meet with and be represented by public health associations. This paper chronicles the history of occupational medicine and industry physicians as influenced and even controlled by corporate leaders.

A Nationwide View of Undergraduates' Interest in Earth-related Careers and Motivation to Tackle Environmental Challenges

2016-12-01

The InTeGrate Attitudinal Instrument (IAI) is an on-line survey that probes students' interest in Earth-related careers, their concern about environmental issues, and their motivation to tackle grand challenges of environmental sustainability and resource limitations. The survey has been taken by several thousand students, at the beginning and end of more than a hundred different undergraduate courses throughout the United States. All courses include some Earth/environmental content, but not all in are geoscience departments. Although results vary somewhat between subpopulations, taken in the aggregate the data paint a nation-wide picture of the state of undergraduates' environmental interests and concerns. Regardless of intended career path, respondents place a high value on working for an organization that is committed to environmentally sustainable practices. Respondents consistently indicate that developments such as global climate change, loss of biodiversity, and water resource limitations are a problem; however, these same students are much less consistent when it comes to engaging in personal behaviors that would help mitigate environmental problems, such as washing clothes in cold water or using recyclable bags when shopping. When asked what factors or sources of information influence their decisions to engage in the specified environmentally sustainable behaviors, the factor most often cited, by a wide margin, is "desire to save money," followed by "concern about pollution." A final open-ended question asked students if they can envision using what they have learned in this course to help society overcome problems of environmental degradation, natural resources limitations, or other environmental issues; if yes, how, and if no, why not. Strong majorities said yes. Among the minority who said no, commonly cited reasons include lack of empowerment (I'm only one person, the problems are too big); course was too general and didn't address solutions; and planning a career path that is not relevant to these problems.

An investigation of the artifacts, outcomes, and processes of constructing computer games about environmental science in a fifth grade science classroom

NASA Astrophysics Data System (ADS)

Baytak, Ahmet

Among educational researchers and practitioners, there is a growing interest in employing computer games for pedagogical purposes. The present research integrated a technology education class and a science class where 5 th graders learned about environmental issues by designing games that involved environmental concepts. The purposes of this study were to investigate how designing computer games affected the development of students' environmental knowledge, programming knowledge, environmental awareness and interest in computers. It also explored the nature of the artifacts developed and the types of knowledge represented therein. A case study (Yin, 2003) was employed within the context of a 5 th grade elementary science classroom. Fifth graders designed computer games about environmental issues to present to 2nd graders by using Scratch software. The analysis of this study was based on multiple data sources: students' pre- and post-test scores on environmental awareness, their environmental knowledge, their interest in computer science, and their game design. Included in the analyses were also data from students' computer games, participant observations, and structured interviews. The results of the study showed that students were able to successfully design functional games that represented their understanding of environment, even though the gain between pre- and post-environmental knowledge test and environmental awareness survey were minimal. The findings indicate that all students were able to use various game characteristics and programming concepts, but their prior experience with the design software affected their representations. The analyses of the interview transcriptions and games show that students improved their programming skills and that they wanted to do similar projects for other subject areas in the future. Observations showed that game design appeared to lead to knowledge-building, interaction and collaboration among students. This, in turn, encouraged students to test and improve their designs. Sharing the games, it was found, has both positive and negative effects on the students' game design process and the representation of students' understandings of the domain subject.

Toxic Release Inventory Chemicals by Groupings

EPA Pesticide Factsheets

The Toxics Release Inventory (TRI) makes available information for more than 600 toxic chemicals that are being used, manufactured, treated, transported, or released into the environment since 1987. EPA makes changes (additions, deletions, or changes in definition) to the TRI chemical list. As a result, the TRI list of reportable toxic chemicals can vary from year to year. EPA created groupings such as the core chemical lists (of 1988, 1991, 1995, 1998, 2000, and 2001) to facilitate year-to-year comparison based on a consistent set of reporting requirements and assure that changes in TRI release or other waste management amounts do not reflect the addition, deletion, or change in definition of reportable chemicals. EPA also created groupings of specific chemicals of interest by categories such as Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), Hazardous Air Pollutants (HAPs), Metals, Newly Added TRI Chemicals in 1995, Occupational Safety and Health Administration (OSHA, Carcinogens), Persistent Bioaccumulative and Toxic (PBT) Chemicals, and Priority Chemicals.

Airborne seafood allergens as a cause of occupational allergy and asthma.

PubMed

Lopata, Andreas L; Jeebhay, Mohamed F

2013-06-01

Occupational allergy and asthma is a serious adverse health outcome affecting seafood-processing workers. Allergic reactions are directed to two major seafood groups: fish and shellfish, with the latter group comprising crustaceans and molluscs. Several allergenic proteins have been identified in these different groups, but few have been characterised on a molecular level. Parvalbumin appears to be the major fish allergen, while tropomyosin the major crustacean allergen. Other IgE-binding proteins have also been identified in molluscs and other seafood-associated agents (e.g. Anisakis sp), although their molecular nature has not been characterised. Aerosolised allergens can be identified and quantified using immunological and chemical approaches, detecting levels as low as 10 ng/m(3). This contemporary review discusses interesting and recent findings in the area of occupational seafood allergy including high-risk occupations, environmental risk factors for airborne exposures, major and minor allergens implicated and innovative approaches in diagnosing and managing occupational allergy and asthma associated with seafood processing.

Environmental confounding in gene-environment interaction studies.

PubMed

Vanderweele, Tyler J; Ko, Yi-An; Mukherjee, Bhramar

2013-07-01

We show that, in the presence of uncontrolled environmental confounding, joint tests for the presence of a main genetic effect and gene-environment interaction will be biased if the genetic and environmental factors are correlated, even if there is no effect of either the genetic factor or the environmental factor on the disease. When environmental confounding is ignored, such tests will in fact reject the joint null of no genetic effect with a probability that tends to 1 as the sample size increases. This problem with the joint test vanishes under gene-environment independence, but it still persists if estimating the gene-environment interaction parameter itself is of interest. Uncontrolled environmental confounding will bias estimates of gene-environment interaction parameters even under gene-environment independence, but it will not do so if the unmeasured confounding variable itself does not interact with the genetic factor. Under gene-environment independence, if the interaction parameter without controlling for the environmental confounder is nonzero, then there is gene-environment interaction either between the genetic factor and the environmental factor of interest or between the genetic factor and the unmeasured environmental confounder. We evaluate several recently proposed joint tests in a simulation study and discuss the implications of these results for the conduct of gene-environment interaction studies.

Acquiring Data by Mining the Past: Pairing Communities with Environmental Monitoring Methods through Open Online Collaborative Replication

Community groups are interested in low-cost sensors to monitor their environment. However, many new commercial sensors are unknown devices without peer-reviewed evaluations of data quality or pathways to regulatory acceptance, and the time to achieve these outcomes may be beyond a community's patience and attention. Rather than developing a device from scratch or validating a new commercial product, a workflow is presented whereby existing technologies, especially those that are out of patent, are replicated through open online collaboration between communities affected by environmental pollution, volunteers, academic institutions, and existing open hardware and open source software projects. Technology case studies will be presented, focusing primarily on a passive PM monitor based on the UNC Passive Monitor. Stages of the project will be detailed moving from identifying community needs, reviewing existing technology, partnership development, technology replication, IP review and licensing, data quality assurance (in process), and field evaluation with community partners (in process), with special attention to partnership development and technology review. We have leveraged open hardware and open source software to lower the cost and access barriers of existing technologies for PM10-2.5 and other atmospheric measures that have already been validated through peer review. Existing validation of and regulatory familiarity with a technology enables a rapid pathway towards collecting data, shortening the time it takes for communities to leverage data in environmental management decisions. Online collaboration requires rigorous documentation that aids in spreading research methods and promoting deep engagement by interested community researchers outside academia. At the same time, careful choice of technology and the use of small-scale fabrication through laser cutting, 3D printing, and open, shared repositories of plans and software enables educational engagement that broadens a project's reach.

Informal environments provide students with unique experiences that allow them to actively participate in activities while promoting a positive attitude toward and an increased interest in science. One way to enhance informal science experiences is through the integration of mobile technologies. This integration is particularly useful in engaging underrepresented students in learning science. Our informal environmental science program engages underrepresented, fifth-grade students in an informal learning environment supplemented with mobile tablet technology (iPads). The purpose of this study was to explore how fifth-grade students interacted with nature using mobile technology during a nature hike series. Participants included 55 fifth-grade students from two low-income schools. We found that students used the mobile technology to explore nature and stay engaged throughout the hike. The iPads were used as references, data collectors, and engagement tools. Students had an intense desire in returning to the site and responded positively toward interacting with nature. Prior research has indicated that students in this age group are likely to lose interest in science and the incorporation of field-friendly technology that engages students with nature, not technology alone, is a useful tool for keeping students interested in science.

Deciphering the crowd: modeling and identification of pedestrian group motion.

Associating attributes to pedestrians in a crowd is relevant for various areas like surveillance, customer profiling and service providing. The attributes of interest greatly depend on the application domain and might involve such social relations as friends or family as well as the hierarchy of the group including the leader or subordinates. Nevertheless, the complex social setting inherently complicates this task. We attack this problem by exploiting the small group structures in the crowd. The relations among individuals and their peers within a social group are reliable indicators of social attributes. To that end, this paper identifies social groups based on explicit motion models integrated through a hypothesis testing scheme. We develop two models relating positional and directional relations. A pair of pedestrians is identified as belonging to the same group or not by utilizing the two models in parallel, which defines a compound hypothesis testing scheme. By testing the proposed approach on three datasets with different environmental properties and group characteristics, it is demonstrated that we achieve an identification accuracy of 87% to 99%. The contribution of this study lies in its definition of positional and directional relation models, its description of compound evaluations, and the resolution of ambiguities with our proposed uncertainty measure based on the local and global indicators of group relation.

Sommerfeld, Johannes; Kroeger, Axel

2012-12-01

This article provides an overview of methods and cross-site insights of a 5-year research and capacity building initiative conducted between 2006 and 2011 in six countries of South Asia (India, Sri Lanka) and South-East Asia (Indonesia, Myanmar, Philippines, Thailand).The initiative managed an interdisciplinary investigation of ecological, biological, and social (i.e., eco-bio-social) dimensions of dengue in urban and peri-urban areas, and developed community-based interventions aimed at reducing dengue vector breeding and viral transmission. The multicountry study comprised interdisciplinary research groups from six leading Asian research institutions. The groups conducted a detailed situation analysis to identify and characterize local eco-bio-social conditions, and formed a community-of-practice for EcoHealth research where group partners disseminated results and collaboratively developed site-specific intervention tools for vector-borne diseases. In sites where water containers produced more than 70% of Aedes pupae, interventions ranged from mechanical lid covers for containers to biological control. Where small discarded containers presented the main problem, groups experimented with solid waste management, composting and recycling schemes. Many intervention tools were locally produced and all tools were implemented through community partnership strategies. All sites developed socially and culturally appropriate health education materials. The study also mobilised and empowered women's, students' and community groups and at several sites organized new volunteer groups for environmental health. The initiative's programmes showed significant impact on vector densities in some sites. Other sites showed varying effect - partially attributable to the 'contamination' of control groups - yet led to significant outcomes at the community level where local groups united around broad interests in environmental hygiene and sanitation. The programme's findings are relevant for defining efficient, effective and ecologically sound vector control interventions based on local evidence and in accordance with WHO's strategy for integrated vector management.

Chemical regulation on fire: rapid policy advances on flame retardants.

PubMed

Cordner, Alissa; Mulcahy, Margaret; Brown, Phil

2013-07-02

Chemicals that are widely used in consumer products offer challenges to product manufacturers, risk managers, environmental regulators, environmental scientists, and the interested public. However, the factors that cause specific chemicals to rise to the level of regulatory, scientific, and social movement concern and scrutiny are not well documented, and scientists are frequently unclear about exactly how their research impacts policy. Through a case study of advocacy around flame retardant chemicals, this paper traces the pathways through which scientific evidence and concern is marshaled by both advocacy groups and media sources to affect policy change. We focus our analysis around a broad coalition of environmental and public health advocacy organizations and an investigative journalism series published in 2012 in the Chicago Tribune. We demonstrate that the Tribune series both brought the issue to a wider public audience and precipitated government action, including state policy revisions and federal Senate hearings. We also show how a broad and successful flame retardant coalition developed, leveraged a media event, and influenced policy at multiple institutional levels. The analysis draws on over 110 in-depth interviews, literature and Web site reviews, and observations at a flame retardant manufacturing company, government offices, and scientific and advocacy conferences.

Despite a great number of published studies addressing estuarine, freshwater and marine bacterial diversity, few have examined urban coastal lagoons in tropical habitats. There is an increasing interest in monitoring opportunistic pathogens as well as indigenous microbial community members in these water bodies by current molecular and microbiological approaches. In this work, bacterial isolates were obtained through selective plate dilution methods to evaluate antibiotic resistances. In addition, 16S rRNA gene libraries were prepared from environmental waters and mixed cultures grown in BHI medium inoculated with Jacarepaguá lagoon waters. Denaturing gradient gel electrophoresis (DGGE) analyses showed distinct community profiles between environmental communities from each studied site and their cultured counterparts. A total of 497 bacterial sequences were analyzed by MOTHUR, yielding 245 operational taxonomic units (OTUs) grouped at 97% similarity. CCA diagrams showcased how several environmental variables affect the distribution of 18 bacterial orders throughout the three distinct habitats. UniFrac metrics and Venn diagrams revealed that bacterial communities retrieved through each experimental approach were significantly different and that only one OTU, closely related to Vibrio cholerae, was shared between them. Potentially pathogenic bacteria were isolated from most sampled environments, fifty percent of which showed antibiotic resistance.

Liu, Ying; Tikunov, Yury; Schouten, Rob E.; Marcelis, Leo F. M.; Visser, Richard G. F.; Bovy, Arnaud

2018-03-01

Anthocyanins are a group of polyphenolic pigments that are ubiquitously found in the plant kingdom. In plants, anthocyanins play a role not only in reproduction, by attracting pollinators and seed dispersers, but also in protection against various abiotic and biotic stresses. There is accumulating evidence that anthocyanins have health-promoting properties, which makes anthocyanin metabolism an interesting target for breeders and researchers. In this review, the state of the art knowledge concerning anthocyanins in the Solanaceous vegetables, i.e. pepper, tomato, eggplant and potato, is discussed, including biochemistry and biological function of anthocyanins, as well as their genetic and environmental regulation. Anthocyanin accumulation is determined by the balance between biosynthesis and degradation. Although the anthocyanin biosynthetic pathway has been well studied in Solanaceous vegetables, more research is needed on the inhibition of biosynthesis and, in particular, the anthocyanin degradation mechanisms if we want to control anthocyanin content of Solanaceous vegetables. In addition, anthocyanin metabolism is distinctly affected by environmental conditions, but the molecular regulation of these effects is poorly understood. Existing knowledge is summarized and current gaps in our understanding are highlighted and discussed, to create opportunities for the development of anthocyanin-rich crops through breeding and environmental management.

Environmental impacts can alter relationships between a coral and its symbiotic microbial community. Furthermore, changes in the microbial community associated with increased seawater temperatures can cause opportunistic infections, coral disease and death. Interactions between soft corals and their associated microbes are not well understood. The species Scleronephthya gracillimum is distributed in tropical to temperate zones in coral assemblages along the Kuroshio Current region. In this study we collected S. gracillimum from various sites at different latitudes, and compared composition of their bacterial communities using Next Generation Sequencing. Coral samples from six geographically distinct areas (two sites each in Taiwan, Japan, and Korea) had considerable variation in their associated bacterial communities and diversity. Endozoicimonaceae was the dominant group in corals from Korea and Japan, whereas Mycoplasma was dominant in corals from Taiwan corals. Interestingly, the latter corals had lower relative abundance of Endozoicimonaceae, but greater diversity. These biogeographic differences in bacterial composition may have been due to varying environmental conditions among study locations, or because of host responses to prevailing environmental conditions. This study provided a baseline for future studies of soft coral microbiomes, and assessment of functions of host metabolites and soft coral holobionts.

Our objective was to describe the healthcare experiences of a diverse, low-income sample of women with prior GDM, including their suggestions for improving care. Methods Focus groups were conducted among African American, Hispanic, and Appalachian women who were diagnosed with GDM within the past 10 years. Participants were recruited from community and medical resources. Twelve focus groups were conducted, four within each race-ethnic group. Results Three broad themes were identified around barriers to GDM care, management, and follow-up: (1) communication issues; (2) personal and environmental barriers; and (3) type and quality of healthcare. Many women felt communication with their provider could be improved, including more education on the severity of GDM, streamlining information to be less overwhelming, and providing additional support through referrals to community resources. Although women expressed interest in receiving more actionable advice for managing GDM during pregnancy and for preventing type 2 diabetes postpartum, few women reported changing behaviors. Barriers to behavior change were related to cost, transportation, and competing demands. Several opportunities for improved care were elucidated. Discussion Our findings suggest that across all racial and ethnic representations in our sample, low-income women with GDM experience similar communication, personal, and environmental barriers related to the healthcare they receive for their GDM. Considering the increased exposure to the health care system during a GDM-affected pregnancy, there are opportunities to address barriers among women with GDM across different race-ethnic groups.

Use of multicriteria decision analysis to address conservation conflicts.

Conservation conflicts are increasing on a global scale and instruments for reconciling competing interests are urgently needed. Multicriteria decision analysis (MCDA) is a structured, decision-support process that can facilitate dialogue between groups with differing interests and incorporate human and environmental dimensions of conflict. MCDA is a structured and transparent method of breaking down complex problems and incorporating multiple objectives. The value of this process for addressing major challenges in conservation conflict management is that MCDA helps in setting realistic goals; entails a transparent decision-making process; and addresses mistrust, differing world views, cross-scale issues, patchy or contested information, and inflexible legislative tools. Overall we believe MCDA provides a valuable decision-support tool, particularly for increasing awareness of the effects of particular values and choices for working toward negotiated compromise, although an awareness of the effect of methodological choices and the limitations of the method is vital before applying it in conflict situations. © 2013 Society for Conservation Biology.

Bacterial RNA Biology on a Genome Scale.

PubMed

Hör, Jens; Gorski, Stanislaw A; Vogel, Jörg

2018-06-07

Bacteria are an exceedingly diverse group of organisms whose molecular exploration is experiencing a renaissance. While the classical view of bacterial gene expression was relatively simple, the emerging view is more complex, encompassing extensive post-transcriptional control involving riboswitches, RNA thermometers, and regulatory small RNAs (sRNAs) associated with the RNA-binding proteins CsrA, Hfq, and ProQ, as well as CRISPR/Cas systems that are programmed by RNAs. Moreover, increasing interest in members of the human microbiota and environmental microbial communities has highlighted the importance of understudied bacterial species with largely unknown transcriptome structures and RNA-based control mechanisms. Collectively, this creates a need for global RNA biology approaches that can rapidly and comprehensively analyze the RNA composition of a bacterium of interest. We review such approaches with a focus on RNA-seq as a versatile tool to investigate the different layers of gene expression in which RNA is made, processed, regulated, modified, translated, and turned over.

Using exposomics to assess cumulative risks and promote health.

PubMed

Smith, Martyn T; de la Rosa, Rosemarie; Daniels, Sarah I

2015-12-01

Under the exposome paradigm all nongenetic factors contributing to disease are considered to be 'environmental' including chemicals, drugs, infectious agents, and psychosocial stress. We can consider these collectively as environmental stressors. Exposomics is the comprehensive analysis of exposure to all environmental stressors and should yield a more thorough understanding of chronic disease development. We can operationalize exposomics by studying all the small molecules in the body and their influence on biological pathways that lead to impaired health. Here, we describe methods by which this may be achieved and discuss the application of exposomics to cumulative risk assessment in vulnerable populations. Since the goal of cumulative risk assessment is to analyze, characterize, and quantify the combined risks to health from exposures to multiple agents or stressors, it seems that exposomics is perfectly poised to advance this important area of environmental health science. We should therefore support development of tools for exposomic analysis and begin to engage impacted communities in participatory exposome research. A first step may be to apply exposomics to vulnerable populations already studied by more conventional cumulative risk approaches. We further propose that recent migrants, low socioeconomic groups with high environmental chemical exposures, and pregnant women should be high priority populations for study by exposomics. Moreover, exposomics allows us to study interactions between chronic stress and environmental chemicals that disrupt stress response pathways (i.e., 'stressogens'). Exploring the impact of early life exposures and maternal stress may be an interesting and accessible topic for investigation by exposomics using biobanked samples. © 2015 Wiley Periodicals, Inc.

Community empowerment needs in the struggle for environmental justice

The paper addresses the specific empowerment needs of communities and workers fighting for environmental justice. Thousands of people of color and poor communities throughout the United States are victimized by policies and practices of environmental racism which resulted in the disproportionate burden of exposure to environmental contamination where they live, work and play. Powerful interests who own and operate polluting industries and waste disposal facilities prey on poor, low income and non-white communities because they view them as areas of least resistance and {open_quotes}sacrifice zones.{close_quotes} Leaders and members of organizations from communities threatened or already devastated by contamination are wagingmore » determined, courageous and heroic struggles against giant corporate polluters. In many instances, the leaders and members of these grassroots environmental groups are literally sick and dying from contamination as they seek to organize for clean, safe and healthy communities. A key issue for communities and workers fighting for environmental justice is realizing true empowerment. Communities and workers must develop empowerment and capacity building skills in the areas of community and labor organizing; media relations and public education; legal advocacy; legislative and regulatory tracking; lobbying; health monitoring and health services; research; scientific technical needs (eg. air, water and soil testing); fundraising and economic sustainable development; institutional and organizational development; voter education and electoral politics; and youth and adult leadership training. When these empowerment skills are combined with a clear vision of justice for the future, communities will be able to fight cooporations armed with high-powered lawyers, lobbyists, public relations firms and bought-off politicians.« less

This study aims to identify the factors that affect consumers purchasing behaviour towards food products that are free from Genetic Modified Organism (GM Free) in a European Region and more precisely in the Prefecture of Drama-Kavala-Xanthi. Field interviews conducted in a random selected sample consisted of 337 consumers in the cities of Drama, Kavala, Xanthi, in November and December of 2009. Principal components analysis (PCA) was conducted in order to identify the factors that affect people in preferring consuming products that are GM Free. The factors that influence people in the study area to buy GM Free products are: (a) products' certification as GM Free or organic products, (b) interest about the protection of the environment and nutrition value, (c) marketing issues, and (d) price and quality. Furthermore, cluster and discriminant analysis identified two groups of consumers: (a) those are influenced by the product price, quality and marketing aspects and (b) those are interested in product's certification and environmental protection. Non parametric statistical bivariate techniques were performed to profile the identified groups of consumers regarding their personal characteristics and some other factors affecting their buying behaviour.

Mushak, Paul; Elliott, Kevin C

2015-12-01

The ability of powerful and well-funded interest groups to steer scientific research in ways that advance their goals has become a significant social concern. This steering ability is increasingly being recognized in the peer-reviewed scientific literature and in findings of deliberative scientific bodies. This paper provides a case study that illustrates some of the major strategies that can be used to structure and advance a controversial research field. It focuses on hormesis, described as a type of dose-response relationship in toxicology and biology showing low-dose stimulation but high-dose inhibition, or the reverse. Hormesis proponents tout its significance, arguing that substances toxic at high doses and beneficial at lower doses should be regulated less stringently. We identify five strategies employed by hormesis proponents to foster its acceptance: (1) creating institutions focused on supporting hormesis; (2) developing terminology, study designs, and data interpretations that cast it in a favorable light; (3) using bibliometric techniques and surveys to attract attention; (4) aggressively advocating for the phenomenon and challenging critics; and (5) working with outside interest groups to apply the hormesis phenomenon in the economic and political spheres. We also suggest a number of oversight strategies that can be implemented to help promote credible and socially responsible research in cases like this one.

Assessing major ecosystem types and the challenge of sustainability in Turkey.

Evrendilek, F; Doygun, H

2000-11-01

In recent years, Turkey has experienced rapid economic and population growth coupled with both an equally rapid increase in energy consumption and a vast disparity in welfare between socioeconomic groups and regions. In turn, these pressures have accelerated the destruction of productive, assimilative, and regenerative capacities of the ecosystems, which are essential for the well-being of the people and the economy. This paper describes the structure and function of major ecosystem types in Turkey and discusses the underlying causes of environmental degradation in the framework of economy, energy, environment, and ethics. From a national perspective, this paper suggests three sustainability-based policies necessary for Turkey's long-term interests that balance economic, environmental, and energy goals: (1) decoupling economic growth from energy consumption growth through the development of energy-efficient and renewable energy technologies; (2) linking economic efficiency and distributive justice of wealth and power through distributive and participatory public policies; and (3) integrating the economic and ecological systems through the internalization of externalities and ecosystem rehabilitation.

Poly(ethylene glycol) and cyclodextrin-grafted chitosan: from methodologies to preparation and potential biotechnological applications

2017-11-01

Chitosan, a polyaminosaccharide obtained by alkaline deacetylation of chitin, possesses useful properties including biodegradability, biocompatibility, low toxicity, and good miscibility with other polymers. It is extensively used in many applications in biology, medicine, agriculture, environmental protection, and the food and pharmaceutical industries. The amino and hydroxyl groups present in the chitosan backbone provide positions for modifications that are influenced by factors such as the molecular weight, viscosity, and type of chitosan, as well as the reaction conditions. The modification of chitosan by chemical methods is of interest because the basic chitosan skeleton is not modified and the process results in new or improved properties of the material. Among the chitosan derivatives, cyclodextrin-grafted chitosan and poly(ethylene glycol)-grafted chitosan are excellent candidates for a range of biomedical, environmental decontamination, and industrial purposes. This work discusses modifications including chitosan with attached cyclodextrin and poly(ethylene glycol), and the main applications of these chitosan derivatives in the biomedical field.

Assessing environmental inequalities in ambient air pollution across urban Australia.

PubMed

Knibbs, Luke D; Barnett, Adrian G

2015-04-01

Identifying inequalities in air pollution levels across population groups can help address environmental justice concerns. We were interested in assessing these inequalities across major urban areas in Australia. We used a land-use regression model to predict ambient nitrogen dioxide (NO2) levels and sought the best socio-economic and population predictor variables. We used a generalised least squares model that accounted for spatial correlation in NO2 levels to examine the associations between the variables. We found that the best model included the index of economic resources (IER) score as a non-linear variable and the percentage of non-Indigenous persons as a linear variable. NO2 levels decreased with increasing IER scores (higher scores indicate less disadvantage) in almost all major urban areas, and NO2 also decreased slightly as the percentage of non-Indigenous persons increased. However, the magnitude of differences in NO2 levels was small and may not translate into substantive differences in health. Copyright © 2015 Elsevier Ltd. All rights reserved.

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.

The politics of global immunization initiatives: can we learn from research on global environmental issues?

PubMed

Sandberg, Kristin Ingstad; Bjune, Gunnar

2007-11-01

The number of institutions, representing different groups of stakeholders and organizations, aiming to coordinate global health policy is on the rise. Yet, as each have distinct interests and priorities, the political dimension becomes an important factor in understanding how institutions work, and how the coordination at the global level affects implementation in countries. This is already a topic for research on global environmental cooperation, inciting the question if one can transfer their analytical framework to the health field. This paper combines a presentation of lessons from research on environmental regimes with a review of global immunization policies and initiatives in order to explore that possibility. The paper describes cooperation on vaccines and immunization according the concepts of institutions and regimes, as defined by international relations research. This description emphasizes efforts to fulfill transnational agreements on objectives, the different ways stakeholders organize and the dynamics of such arrangements. An account of the research practice on global environmental cooperation leads to a discussion of how one could adapt the analytical framework. The paper makes the case for the development of a research program, where the analytical approach is modified to account for the interaction between technology production and public-led institutions. The conclusion proposes a number of entry points to research that have already yielded policy-relevant knowledge in the environmental field. These include the formation of new institutions, the contribution of institutional design to effective implementation, and the interplay between vaccine initiatives and other global institutions.

Boiling points of halogenated aliphatic compounds: a quantitative structure-property relationship for prediction and validation.

PubMed

Oberg, Tomas

2004-01-01

Halogenated aliphatic compounds have many technical uses, but substances within this group are also ubiquitous environmental pollutants that can affect the ozone layer and contribute to global warming. The establishment of quantitative structure-property relationships is of interest not only to fill in gaps in the available database but also to validate experimental data already acquired. The three-dimensional structures of 240 compounds were modeled with molecular mechanics prior to the generation of empirical descriptors. Two bilinear projection methods, principal component analysis (PCA) and partial-least-squares regression (PLSR), were used to identify outliers. PLSR was subsequently used to build a multivariate calibration model by extracting the latent variables that describe most of the covariation between the molecular structure and the boiling point. Boiling points were also estimated with an extension of the group contribution method of Stein and Brown.

The high prevalence of chronic illnesses in South Asian Indian immigrant women underscores the need for identifying factors that could influence their PA. The purpose of this qualitative study was to examine the perspectives of South Asian Indian immigrant women related to barriers to and motives for lifestyle PA within the PA Framework for South Asian Indian Immigrants. Forty women participated in focus groups that were conducted in English and Hindi. Focus group questions were open-ended and semistructured. Transcribed and de-identified audiotaped sessions were coded and analyzed using Atlas.ti software. Role expectation was a core theme for barriers with four subthemes: lack of time, loss of interest, diminished social support, and environmental constraints. Self-motivation was a core theme for motives with three subthemes: optimal physical and psychological health, emphasis on external beauty, and strong social support. Future PA interventions need to target these culturally sensitive factors.

Linear solvation energy relationships (LSER): 'rules of thumb' for Vi/100, π*, Βm, and αm estimation and use in aquatic toxicology

This chapter provides a listing of the increasing variety of organic moieties and heteroatom group for which Linear Solvation Energy Relationship (LSER) values are available, and the LSER variable estimation rules. The listings include values for typical nitrogen-, sulfur- and phosphorus-containing moieties, and general organosilicon and organotin groups. The contributions by an ion pair situation to the LSER values are also offered in Table 1, allowing estimation of parameters for salts and zwitterions. The guidelines permit quick estimation of values for the four primary LSER variables Vi/100, π*, Βm, and αm by summing the contribtuions from its components. The use of guidelines and Table 1 significantly simplifies computation of values for the LSER variables for most possible organic comppounds in the environment, including the larger compounds of environmental and biological interest.

Investigating the impact of adding an environmental focus to a developmental chemistry class

NASA Astrophysics Data System (ADS)

Robelia, Beth A.

Making chemistry more relevant to students has been a goal of many curriculum projects. None of these projects have investigated how specific applications of chemistry impact student learning or environmental mindset. The goal of this study was to examine how focusing attention on environmental issues as applications of chemistry concepts would affect students' understanding of general chemistry or environmental chemistry as well environmental attitudes, behaviors and knowledge. Special attention was paid to how women responded to the addition of an environmental focus because prior research indicated women hold more pro-environmental attitudes but are less knowledgeable about environmental topics. The quasi-experimental design used two treatment groups and a comparison group. Both treatment groups received instruction with a Science-Technology-Society orientation, one group focused on environmental applications of chemistry while the other drew applications of chemistry from a number of different fields students might be familiar with such as health care, food science and forensics. The comparison groups used mainly traditional examples from chemistry laboratories. In order to avoid testing the effect of the instructor, two people co-taught both treatment sections. Students in all three groups took a general chemistry assessment at the beginning and end of the course. The treatment groups took a pre and post environmental chemistry assessment and a survey of their environmental attitudes, behaviors and knowledge. Results indicate that students in the environmentally focused section may have made slight gains in general chemistry knowledge. Gains in environmental chemistry knowledge were not significantly different. Students also made modest gains in environmental attitude. Results for women mirrored results for the classes as a whole.

Geoscience is a multi-disciplinary field and in many cases its research benefits from considering different kinds of observational results. Geoscience observations are in some cases of direct interest also to the public. For these reasons effective knowledge transfer and access also across disciplines are especially important for research infrastructures (RIs) in the environmental domain. More generally, the ultimate success of a RI is measured by its scientific outcome and this is best achieved based on efficient access for a broad scientific community. In this presentation the authors report activities to develop governance tools so that the access to environmental RIs and to the data that they provide is common, fair and based on scientific rationale, regarding at the same time economically and technically reasonable use of limited resources. Implementing such governance tools will indeed foster and widen the access to RIs across environmental science domains while addressing societal challenges. The strategies also need to be flexible and sustainable over the expected lifetimes of the RIs. The reported activities involve researchers from different projects and environmental subdomains that come together in the project ENVRI_plus. ENVRI_plus is a Cluster project of RIs that brings together the current ESFRI roadmap RIs in the environmental domain and other relevant existing and developing RIs and projects. ENVRI_plus also offers opportunities for free-of-charge transnational access to four multi-disciplinary research platforms. These calls for access target research groups and companies wishing to conduct research or to test instruments for cross-disciplinary topics within the environmental domains atmosphere, biosphere, marine, and solid earth. They are initiated specifically to gain experience with access across different disciplines (further information is given at www.envriplus.eu). ENVRI_plus receives funding from the European Union's Horizon 2020 research and innovation programme under grant agreement No 654182.

Rural cancer disparities are increasingly documented in the USA. Research has identified and begun to address rural residents' cancer knowledge and behaviors, especially among women. Little, however, is known about rural female residents' awareness of cancer inequities and perceived contributing factors affecting them and their families. The purpose of this study was to address these gaps in the literature via a secondary analysis of qualitative needs assessment in Illinois' rural southernmost seven counties, a geographic region with relatively high rates of cancer incidence, morbidity, and mortality. A convenience sample of 202 rural adult female residents was recruited and participated in 26 focus groups, with 3-13 women per group. Inductive content analysis, guided by the principle of constant comparison, was used to analyze the qualitative data. Most respondents indicated their awareness of disproportionate cancer burden in their communities. Individual-level behaviors and environmental toxins were identified as contributing factors. Interestingly, however, environmental toxins were more often discussed as factors contributing to geographic differences, whereas individual-level behaviors were noted as important for overall cancer prevention and control. This study provides important insight into female rural residents' perspectives and offers novel venues for educational programs and research in the context of communication to eliminate disparities.

Bringing Up Girls in Science (BUGS) was an afterschool program for 4th and 5th grade girls that provided authentic learning experiences in environmental science as well as valuable female mentoring opportunities in an effort to increase participants' academic achievement in science. BUGS participants demonstrated significantly greater amounts of gain in science knowledge as measured by the Iowa Test of Basic Skills in Science (ITBS-S). The original BUGS participants and contrasts have now completed high school and entered college, allowing researchers to assess the long-term impact of the BUGS program. Fourteen former BUGS participants completed two instruments to assess their perceptions of science and science, technology, engineering, and mathematics (STEM) careers. Their results were compared to four contrast groups composed entirely of females: 12 former BUGS contrasts, 10 college science majors, 10 non-science majors, and 9 current STEM professionals. Results indicate that BUGS participants have higher perceptions of science careers than BUGS contrasts. There were no significant differences between BUGS participants, Science Majors, and STEM professionals in their perceptions of science and STEM careers, whereas the BUGS contrast group was significantly lower than BUGS participants, Science Majors, and STEM Professionals. Additional results and implications are discussed within.

The dead wood and forest soils are sources of diversity and under-explored fungal strains with biotechnological potential, which require to be studied. Numerous enzymatic tests have been proposed to investigate the functional potential of the soil microbial communities or to test the functional abilities of fungal strains. Nevertheless, the diversity of these functional markers and their relevance in environmental studies or biotechnological screening does still have not been demonstrated. In this work, we assessed ten different extracellular enzymatic activities involved in the wood decaying process including β-etherase that specifically cleaves the β-aryl ether linkages in the lignin polymer. For this purpose, a collection of 26 fungal strains, distributed within three ecological groups (white, brown and soft rot fungi), has been used. Among the ten potential functional markers, the combinatorial use of only six of them allowed separation between the group of white and soft rot fungi from the brown rot fungi. Moreover, our results suggest that extracellular β-etherase is a rare and dispensable activity among the wood decay fungi. Finally, we propose that this set of markers could be useful for the analysis of fungal communities in functional and environmental studies, and for the selection of strains with biotechnological interests.

Among them microsensors based on semiconductor technology offer additional advantages such as small size, robustness, low output impedance and rapid response. Besides, the technology used allows integration of circuitry and multiple sensors in the same substrate and accordingly they can be implemented in compact probes for particular applications e.g., in situ monitoring and/or on-line measurements. In the field of microsensors for environmental applications, Ion Selective Field Effect Transistors (ISFETs) have a special interest. They are particularly helpful for measuring pH and other ions in small volumes and they can be integrated in compact flow cells for continuous measurements. In this paper the technologies used to fabricate ISFETs and a review of the role of ISFETs in the environmental field are presented. PMID:22315527

Risk Perception of Radiation Exposure of Villagers Living Near the Semipalatinsk Nuclear Test Site

NASA Astrophysics Data System (ADS)

Purvis-Roberts, K. L.

2006-12-01

Connecting scientific data to societal needs is particularly important with the complex environmental issues that face us in the near future, such as global warming and natural hazards. Once the scientific data is collected and analyzed, dissemination of the results needs to be communicated to the public in a way that can be easily understood without glossing over the complexity of the issue. An interesting case study derives from the primary nuclear test site for the former Soviet Union, located near the city of Semipalatinsk, Kazakhstan. Villagers living directly adjacent to the Semipalatinsk Nuclear Test Site (SNTS) were exposed continuously to radioactive clouds from atmospheric, above ground and underground nuclear tests. The people living in the region are still exposed to low levels of radiation through the environmental contamination of their food and water and have experienced a higher incidence of cancers and birth defects than people living in other regions of the country. A database of historical environmental data was collected throughout the nuclear testing period by the Soviet government, tracking radiation concentrations through food, water, and soil samples around the SNTS, but this environmental data was never shared with the villagers. In fact, only after the Soviet Union fell apart in 1989 did the people discover that they had been exposed to radiation during the past 40 years. Through preliminary interviews with villagers, physicians, and scientists who live near the SNTS, it was discovered that the three groups viewed the risk of radiation exposure very differently. By developing a risk perception survey to understand how the different groups perceived radiation risk, and then comparing the scientific data to the survey results, a better way to communicate the risk could be developed. The risk perception survey was given to over 800 people in East Kazakhstan Oblast, including villagers living near the SNTS, scientists who study the environmental impacts on the test site, and physicians who treat those affected by the radiation exposure in the region. A comparison of perceived risk in relation to the environmental data will be discussed in addition to potential ways to communicate actual risk.

Enacting cultural interests: how intergroup contact reduces prejudice by sparking interest in an out-group's culture.

PubMed

Brannon, Tiffany N; Walton, Gregory M

2013-10-01

In the present research, we examined the hypothesis that cues of social connectedness to a member of another social group can spark interest in the group's culture, and that such interest, when freely enacted, contributes to reductions in intergroup prejudice. In two pilot studies and Experiment 1, we found that extant and desired cross-group friendships and cues of social connectedness to an out-group member predicted increased interest in the target group's culture. In Experiments 2 and 3, we manipulated cues of social connectedness between non-Latino American participants and a Latino American (i.e., Mexican American) peer and whether participants freely worked with this peer on a Mexican cultural task. This experience reduced the participants' implicit bias against Latinos, an effect that was mediated by increased cultural engagement, and, 6 months later in an unrelated context, improved intergroup outcomes (e.g., interest in interacting with Mexican Americans; Experiment 4). The Discussion section addresses the inter- and intragroup benefits of policies that encourage people to express and share diverse cultural interests in mainstream settings.

The detection of diverse aminoglycoside phosphotransferases within natural populations of actinomycetes.

PubMed

Anderson, A S; Clark, D J; Gibbons, P H; Sigmund, J M

2002-08-01

The conserved nature of the genes that code for actinomycete secondary metabolite biosynthetic pathways suggests a common evolutionary ancestor and incidences of lateral gene transfer. Resistance genes associated with these biosynthetic pathways also display a high degree of similarity. Actinomycete aminoglycoside phosphotransferase antibiotic resistance enzymes (APH) are coded for by such genes and are therefore good targets for evaluating the bioactive potential of actinomycetes. A set of universal PCR primers for APH encoding genes was used to probe genomic DNA from three collections of actinomycetes to determine the utility of molecular screening. An additional monitoring of populations for the predominance of specific classes of enzymes to predict the potential of environmental sites for providing isolates with interesting metabolic profiles. Approximately one-fifth of all isolates screened gave a positive result by PCR. The PCR products obtained were sequenced and compared to existing APH family members. Sequence analysis resolved the family into nine groups of which six had recognizable phenotypes: 6'-phosphotransferase (APH(6)), 3'-phosphotransferase (APH(3)), hydroxyurea phosphotransferase (HUR), peptide phosphotransferase, hygromycin B phosphotransferase (APH(7")) and oxidoreductase. The actinomycetes screened fell into seven groups, including three novel groups with unknown phenotypes. The strains clustered according to the environmental site from where they were obtained, providing evidence for the movement of these genes within populations. The value of this as a method for obtaining novel compounds and the significance to the ecology of antibiotic biosynthesis are discussed.

Interest Rate Demands and Television Viewing-Is a Single Exposure More Influential Than Routine Viewing?

PubMed

Hetsroni, Amir; Reizer, Abira; Ben Zion, Uri

2017-04-01

This study examined the impact of media consumption, and particularly exposure to television, on decisions regarding interest rate demands. One hundred and fifty-four participants were randomly divided into two groups: in the manipulation group, participants were exposed to a news clip about an Iranian nuclear attack on Israel, whereas in the control group, the participants were not exposed to the film. Both groups filled a questionnaires regarding their interest rate requirements in different situations, their media conception behaviors, and demographic questionnaires. Frequent routine viewing increased the interest rate demands only among participants in the manipulation group, but the manipulation itself did not have a significant effect on interest rate demands. The results are explained in terms of cultivation theory.

Palaeoenvironmental drivers of vertebrate community composition in the Belly River Group (Campanian) of Alberta, Canada, with implications for dinosaur biogeography.

PubMed

Cullen, Thomas M; Evans, David C

2016-11-15

The Belly River Group of southern Alberta is one of the best-sampled Late Cretaceous terrestrial faunal assemblages in the world. This system provides a high-resolution biostratigraphic record of terrestrial vertebrate diversity and faunal turnover, and it has considerable potential to be a model system for testing hypotheses of dinosaur palaeoecological dynamics, including important aspects of palaeoecommunity structure, trophic interactions, and responses to environmental change. Vertebrate fossil microsites (assemblages of small bones and teeth concentrated together over a relatively short time and thought to be representative of community composition) offer an unparalleled dataset to better test these hypotheses by ameliorating problems of sample size, geography, and chronostratigraphic control that hamper other palaeoecological analyses. Here, we assembled a comprehensive relative abundance dataset of microsites sampled from the entire Belly River Group and performed a series of analyses to test the influence of environmental factors on site and taxon clustering, and assess the stability of faunal assemblages both temporally and spatially. We also test the long-held idea that populations of large dinosaur taxa were particularly sensitive to small-scale environmental gradients, such as the paralic (coastal) to alluvial (inland) regimes present within the time-equivalent depositional basin of the upper Oldman and lower Dinosaur Park Formations. Palaeoenvironment (i.e. reconstructed environmental conditions, related to relative amount of alluvial, fluvial, and coastal influence in associated sedimentary strata) was found to be strongly associated with clustering of sites by relative-abundance faunal assemblages, particularly in relation to changes in faunal assemblage composition and marine-terrestrial environmental transitions. Palaeogeography/palaeolandscape were moderately associated to site relative abundance assemblage clustering, with depositional setting and time (i.e. vertical position within stratigraphic unit) more weakly associated. Interestingly, while vertebrate relative abundance assemblages as a whole were strongly correlated with these marine-terrestrial transitions, the dinosaur fauna does not appear to be particularly sensitive to them. This analysis confirms that depositional setting (i.e. the sediment type/sorting and associated characteristics) has little effect on faunal assemblage composition, in contrast to the effect of changes in the broader palaeoenvironment (e.g. upper vs. lower coastal plain, etc.), with marine-terrestrial transitions driving temporal faunal dynamics within the Belly River Group. The similarity of the dinosaur faunal assemblages between the time-equivalent portions of the Dinosaur Park Formation and Oldman Formation suggests that either these palaeoenvironments are more similar than characterized in the literature, or that the dinosaurs are less sensitive to variation in palaeoenvironment than has often been suggested. A lack of sensitivity to subtle environmental gradients casts doubt on these forces acting as a driver of putative endemism of dinosaur populations in the Late Cretaceous of North America.

Keep calm and carry on: the 2009 NEHA sabbatical exchange ambassador report.

2011-06-01

Sabbatical goal as an environmental health specialist working with the California Department of Public Health as an emergency planner, I was interested in the NEHA sabbatical exchange program for the opportunity it affords its awardees to see how Canada and the United Kingdom utilize their environmental health workforce. Specifically, I wanted to examine the role environmental health has in the preparations being made for the 2012 Olympic Games to be held in London. I had a special interest in the emergency preparedness efforts related to the games as my work involves promoting the integration of environmental health into the emergency response structure. In California, environmental health services are delivered by several state agencies as well as 62 local jurisdictions. This multifaceted system tends to diminish the important role environmental health plays in disaster response and recovery operations due to the lack of a central focus, and as a result, environmental health is often an overlooked resource. This situation is not unique to California, as the emergency management system in the U.S. has traditionally focused primarily on "blue light" first responders: police, fire, and emergency medical services. After an article caught my eye on involving environmental health in emergency planning, posted on the Chartered Institute of Environmental Health (CIEH) (NEHA's counterpart in the UK) Web site, I became intrigued and used it to form the basis of my sabbatical mission.

Environmental groups are particularly unhappy with the Synthetic Fuels Corporation and the Clinch River Breeder Reactor; they will waste more energy than they make, complains Palmer. When resources are cheap or free, they tend to be abused. Environmentalists have discovered the market helps allay this overuse.

Predators and the public trust.

Treves, Adrian; Chapron, Guillaume; López-Bao, Jose V; Shoemaker, Chase; Goeckner, Apollonia R; Bruskotter, Jeremy T

2017-02-01

Many democratic governments recognize a duty to conserve environmental resources, including wild animals, as a public trust for current and future citizens. These public trust principles have informed two centuries of U.S.A. Supreme Court decisions and environmental laws worldwide. Nevertheless numerous populations of large-bodied, mammalian carnivores (predators) were eradicated in the 20th century. Environmental movements and strict legal protections have fostered predator recoveries across the U.S.A. and Europe since the 1970s. Now subnational jurisdictions are regaining management authority from central governments for their predator subpopulations. Will the history of local eradication repeat or will these jurisdictions adopt public trust thinking and their obligation to broad public interests over narrower ones? We review the role of public trust principles in the restoration and preservation of controversial species. In so doing we argue for the essential roles of scientists from many disciplines concerned with biological diversity and its conservation. We look beyond species endangerment to future generations' interests in sustainability, particularly non-consumptive uses. Although our conclusions apply to all wild organisms, we focus on predators because of the particular challenges they pose for government trustees, trust managers, and society. Gray wolves Canis lupus L. deserve particular attention, because detailed information and abundant policy debates across regions have exposed four important challenges for preserving predators in the face of interest group hostility. One challenge is uncertainty and varied interpretations about public trustees' responsibilities for wildlife, which have created a mosaic of policies across jurisdictions. We explore how such mosaics have merits and drawbacks for biodiversity. The other three challenges to conserving wildlife as public trust assets are illuminated by the biology of predators and the interacting behavioural ecologies of humans and predators. The scientific community has not reached consensus on sustainable levels of human-caused mortality for many predator populations. This challenge includes both genuine conceptual uncertainty and exploitation of scientific debate for political gain. Second, human intolerance for predators exposes value conflicts about preferences for some wildlife over others and balancing majority rule with the protection of minorities in a democracy. We examine how differences between traditional assumptions and scientific studies of interactions between people and predators impede evidence-based policy. Even if the prior challenges can be overcome, well-reasoned policy on wild animals faces a greater challenge than other environmental assets because animals and humans change behaviour in response to each other in the short term. These coupled, dynamic responses exacerbate clashes between uses that deplete wildlife and uses that enhance or preserve wildlife. Viewed in this way, environmental assets demand sophisticated, careful accounting by disinterested trustees who can both understand the multidisciplinary scientific measurements of relative costs and benefits among competing uses, and justly balance the needs of all beneficiaries including future generations. Without public trust principles, future trustees will seldom prevail against narrow, powerful, and undemocratic interests. Without conservation informed by public trust thinking predator populations will face repeated cycles of eradication and recovery. Our conclusions have implications for the many subfields of the biological sciences that address environmental trust assets from the atmosphere to aquifers. © 2015 The Authors.

Views of potential research participants on financial conflicts of interest: barriers and opportunities for effective disclosure.

There is little guidance regarding how to disclose researchers' financial interests to potential research participants. To determine what potential research participants want to know about financial interests, their capacity to understand disclosed information and its implications, and the reactions of potential research participants to a proposed disclosure statement. Sixteen focus groups in 3 cities, including 6 groups of healthy adults, 6 groups of adults with mild chronic illness, 1 group of parents of healthy children, 1 group of parents of children with leukemia or brain tumor, 1 group of adults with heart failure, and 1 group of adults with cancer. Focus group discussions covered a range of topics including financial relationships in clinical research, whether people should be told about them, and how they should be told. Audio-recordings of focus groups were transcribed, verified, and coded for analysis. Participants wanted to know about financial interests, whether or not those interests would affect their participation. However, they varied in their desire and ability to understand the nature and implications of financial interests. Whether disclosure was deemed important depended upon the risk of the research. Trust in clinicians was also related to views regarding disclosure. If given the opportunity to ask questions during the consent process, some participants would not have known what to ask; however, after the focus group sessions, participants could identify information they would want to know. Financial interests are important to potential research participants, but obstacles to effective disclosure exist.

Enzymatic characterization of clinical and environmental Cryptococcus neoformans strains isolated in Italy.

PubMed

Pini, Gabriella; Faggi, Elisabetta; Campisi, Enza

Cryptococcus neoformans is an encapsulated yeast causing mainly opportunistic infections. The virulence factors involved in cryptococcosis pathogenesis include the presence and the size of the polysaccharide capsule, the production of melanin by phenoloxidase, the growth at 37°C and the enzyme secretion like proteinase, phospholipase and urease. Many other enzymes are secreted by C. neoformans but their role in the fungus virulence is not yet known. In order to investigate this topic, we compared the phospholipase production between strains from patients and from bird droppings, and we examined its relationship to phenoloxidase production. We further characterized the strains by determining the activity of 19 different extracellular enzymes. Two hundred and five Italian C. neoformans clinical isolates and 32 environmental isolates were tested. Phenoloxidase production was determined by the development of brown colonies on Staib's agar. Extracellular phospholipase activity was performed using the semiquantitative egg-yolk plate method. API ZYM commercial kit was used to observe the production and the activity of 19 different extracellular enzymes. Statistical analysis of the results showed a significantly higher phospholipase activity in the clinical isolates than in the environmental isolates. No significant difference about the phenoloxidase production between both groups was found. Regarding the 19 extracellular enzymes tested using the API ZYM commercial kit, acid phosphatase showed the highest enzymatic activity in both groups. Concerning the enzyme α-glucosidase, the clinical isolates presented a significantly higher positivity percentage than the environmental isolates. A hundred percent positivity in the enzyme leucine arylamidase production was observed in both groups, but the clinical isolates metabolized a significantly greater amount of substrate. The higher phospholipase production in the clinical isolates group confirms the possible role of this enzyme in the cryptococcosis pathogenesis. The extracellular activities of the enzymes acid phosphatase, α-glucosidase and leucine arylamidase, tested by means of the API ZYM commercial kit, appear to be very interesting. Many studies indicate that these enzymes are involved in the virulence of bacteria and parasites; our results suggest their possible role as virulence factors in Cryptococcus infections too.

River Basin Scale Management and Governance: Competing Interests for Western Water

NASA Astrophysics Data System (ADS)

Lindquist, Eric

2015-04-01

One of the most significant issues in regard to how social scientists understand environmental and resource management is the question of scale: what is the appropriate scale at which to consider environmental problems, and associated stakeholders (including hydrologists) and their interests, in order to "govern" them? Issues of scale touch on the reality of political boundaries, from the international to the local, and their overlap and conflict across jurisdictions. This presentation will consider the questions of environmental management and governance at the river basin scale through the case of the Boise River Basin (BRB), in southwest Idaho. The river basin scale provides a viable, and generalizable, unit of analysis with which to consider theoretical and empirical questions associated with governance and the role of hydrological science in decision making. As a unit of analysis, the "river basin" is common among engineers and hydrologists. Indeed, hydrological data is often collected and assessed at the basin level, not at an institutional or jurisdictional level. In the case of the BRB much is known from the technical perspective, such as infrastructure and engineering factors, who manages the river and how, and economic perspectives, in regard to benefits in support of major agricultural interests in the region. The same level of knowledge cannot be said about the political and societal factors, and related concepts of institutions and power. Compounding the situation is the increasing probability of climate change impacts in the American West. The geographic focus on the Boise River Basin provides a compelling example of what the future might hold in the American West, and how resource managers and other vested interests make or influence river basin policy in the region. The BRB represents a complex and dynamic environment covering approximately 4,100 square miles of land. The BRB is a highly managed basin, with multiple dams and diversions, and is regarded as a highly desirable amenity and ecosystem service provider for the region. It is also a very polarizing construct as diverse interests engaged in basin decision making do not share the same values, perceptions, and constituents. Although regulatory and jurisdictional decision making is in the hands of a few agencies (US Army Corps of Engineers and US Bureau of Reclamation, for example), it is estimated that up to 300 different interests and groups are engaged in using, supporting, and attempting to influence the decisions associated with the Boise River and its myriad uses. Building on previous river basin governance research in the US and Europe, the work presented here is framed on a policy network approach, and focuses on four main factors of the BRB: the type of stakeholder and their perceptions of the BRB as a resource or amenity, role(s) of the stakeholder in the network, interactions between network members and the public, and the role of science, uncertainty and the impact of climate change. This contribution addresses many of the question raised in the HS5.7 call for abstracts and will be of interest to a wide audience.

History-Based Instruction Enriched with Various Sources of Situational Interest on the Topic of the Atom: the Effect on Students' Achievement and Interest

This study examines the effect of history-based instruction on the topic of the atom on students' academic achievement and their interest in the history of science, investigating as well the relationship between student interest and academic achievement. The sample of the study consisted of two groups of freshman students from an undergraduate elementary science teachers program. The same chemistry instructor taught the groups, which were randomly assigned as an experimental and a control group. The students in the control group received traditional teacher-centered instruction, while the experimental group students were taught the topic of the atom using history-based instruction enriched with various sources of situational interest such as novelty, autonomy, social involvement, and knowledge acquisition (NASK). Data gathering instruments were the Atom Achievement Test and the History of Science Interest Scale, administered to both of the groups before and after the instruction. The data were analyzed with the independent-samples t test, the paired-samples t test, and one-way ANCOVA statistical analysis. The results showed that the history-based instruction including NASK was more effective than traditional instruction in improving the students' learning of the subject of the atom as well as in stimulating and improving students' interest in the history of science. Further, students with high interest displayed significantly better achievement than students with low interest. The better learning of the topic of the atom was more pronounced in the case of students with a high interest in the history of science compared to students with moderate or low interest.

A growing need for broad dissemination of current scientific research and improved scientific literacy requires new models of professional development that allow for direct collaboration between educators and university researchers. One example is a project funded by the National Science Foundation (NSF) as part of a study titled, "Reconstructing 2500 years of environmental change at the periphery of Rome: Integrating paleoecology and socioeconomic history to understand human response to climate." This project involves a team of middle school teachers working with researchers at the University of Nevada, Reno (UNR) to gain first-hand knowledge in multidisciplinary research connecting science and society, and applies a similar approach in the classroom. In 2013, the team's science teacher traveled to Italy as a member of the science research group. A series of workshops introduced the remaining teachers to the research project. Teachers collaborated to develop a Project Based Learning (PBL) unit that incorporated Next Generation Science Standards and encompassed English, Social Studies, Math, and Science curricula using a pedagogical approach different from the single subject-based PBL's usually taught in their school district. The PBL unit draws on the NSF study and focuses on exploring the balance between economic and environmental issues surrounding local wetlands. In May 2014, 160 middle school students worked in groups to create and test a question about physio-chemical parameters in a nearby wetland and used these data to discuss local economic development. Initially, students claimed polarized views of environmental issues or economic development interests; however, during a multimedia session showcasing results, students communicated more informed perspectives that clearly incorporated knowledge gained from their own research. Some students were able to make recommendations for good practices involving planned economic development near the wetland. Preliminary outcomes suggests this model: 1) permits authentic exploration of the role of scientific research in making informed policy decisions; 2) promotes diverse perspectives when approaching environmental and socioeconomic problems; and 3) enhances group engagement in developing scientific literacy.

The massive publicity surrounding the exodus of residents from New Orleans spurred by Hurricane Katrina has encouraged interest in the ways that past migration in the U.S. has been shaped by environmental factors. So has Timothy Egan's exciting book, The Worst Hard Time: The Untold Story of those who survived the Great American Dust Bowl. This paper places those dramatic stories into a much less exciting context, demonstrating that the kinds of environmental factors exemplified by Katrina and the Dust Bowl are dwarfed in importance and frequency by the other ways that environment has both impeded and assisted the forces of migration. We accomplish this goal by enumerating four types of environmental influence on migration in the U.S.: 1) environmental calamities, including floods, hurricanes, earthquakes, and tornadoes, 2) environmental hardships and their obverse, short-term environmental benefits, including both drought and short periods of favorable weather, 3) environmental amenities, including warmth, sun, and proximity to water or mountains, and 4) environmental barriers and their management, including heat, air conditioning, flood control, drainage, and irrigation. In U.S. history, all four of these have driven migration flows in one direction or another. Placing Katrina into this historical context is an important task, both because the environmental calamities of which Katrina is an example are relatively rare and have not had a wide impact, and because focusing on them defers interest from the other kinds of environmental impacts, whose effect on migration may have been stronger and more persistent, though less dramatic.

Ethics Guidelines in Environmental Epidemiology: Their Development and Challenges We Face.

Kramer, Shira; Soskolne, Colin L

2017-06-01

This review integrates historical developments and key events in bringing ethics into epidemiology in general and into environmental epidemiology in particular. The goal is to provide context for and discern among the various approaches and motivations that drive the need for ethical conduct in support of the public interest. The need for ethics guidelines in epidemiology is different from developments in other biomedical-related fields by virtue of its focus on populations rather than on individuals. The need for ethics guidelines in environmental epidemiology as a subspecialty of epidemiology stems from the larger scale of its mission than that of epidemiology per se. Ethics guidelines in the field of environmental epidemiology have been established. They articulate not only the profession's core values and mission, but more specifically, they address the environmental epidemiologist's obligations to the participants in research, to colleagues, and to employers. They are the product of consensus, scholarship, and diligent stewardship over several decades. The next challenge is ensuring their value and impact. The forces that support professional and institutional success, and the power of special interests, are the major threats to achieving the goals of ethical conduct and research for the public good. In environmental epidemiology, these threats have global implications.

Among various two-dimensional (2D) materials, monolayer group-III monochalcogenides (GaS, GaSe, InS, and InSe) stand out owing to their potential applications in microelectronics and optoelectronics. Devices made of these novel 2D materials are sensitive to environmental gases, especially O2 molecules. To address this critical issue, here we systematically investigate the oxidization behaviors of perfect and defective group-III monochalcogenide monolayers by first-principles calculations. The perfect monolayers show superior oxidation resistance with large barriers of 3.02-3.20 eV for the dissociation and chemisorption of O2 molecules. In contrast, the defective monolayers with single chalcogen vacancy are vulnerable to O2, showing small barriers of only 0.26-0.36 eV for the chemisorption of an O2 molecule. Interestingly, filling an O2 molecule to the chalcogen vacancy of group-III monochalcogenide monolayers could preserve the electronic band structure of the perfect system—the bandgaps are almost intact and the carrier effective masses are only moderately disturbed. On the other hand, the defective monolayers with single vacancies of group-III atoms carry local magnetic moments of 1-2 μB. These results help experimental design and synthesis of group-III monochalcogenides based 2D devices with high performance and stability.

The study focused on the effects of the Malaysian Department of Wildlife and National Park's (DWNP) environmental education program on the environmental knowledge and attitudes of the secondary school students. Conducted between May 11, 1998 and August 11, 1998, this study was designed to reflect three objectives: (1) to determine the effect of participation in the DWNP's environmental education program on environmental knowledge and attitudes of 13--17 year old Malaysian students, (2) to identify demographic factors that contribute to the change of environmental knowledge and attitudes, and (3) to establish base line data for future evaluation of the effectiveness of DWNP's environmental education program. The sample was comprised of 806 randomly selected students from 10 different schools, with 402 randomly assigned to the experimental grouped and 404 to the control group. Pretest and post-tests were administered at the schools. The experimental group was exposed to the Environmental Education Program (EEP) at the Environmental Education Center (EEC) at Bukit Rengit, Lanchang, Pahang, Malaysia sometime between May 14, 1998 and August 8, 1998. At the EEC, the experimental group was again divided, with half receiving the pretest and post-test, while the other half were given only the post-test. The instrument used in this study was a modification of the Children's Environmental Attitudes and Knowledge Scale (CHEAKS) developed by Leeming, et al. (1995). This instrument had sound psychometric properties suitable for this research setting, and allowed comparisons of results with previous studies. T-tests, ANOVA, and ANCOVA were used to determine group differences. Overall, secondary school students in the experimental group showed a significantly greater change in environmental knowledge than did students in the control group. Significant differences were also found on the Attitude sub-scale, with the control group exhibiting negative change in attitude, and slightly change occurring in the attitudes of the experimental group. There were no significant differences of the change in environmental knowledge and attitude across age and place of residence than did gender of the EEP participants. The trend of changes in environmental knowledge and attitude between school and EEC were shown negatively. Changes in both environmental knowledge and attitude began to increase but change in knowledge exceeded the change in attitude when measured between the pre and post-tests at the EEC. However, there was slightly increased in attitude toward environmental matters as compared to the change in environmental knowledge after the participants had been measured between the EEC and the school.
