    The carbon disclosure project conducts an annual survey to determine the strategies and actions of major cap companies in relation to climate change. This report discussed initiatives implemented by Canada's largest companies to prepare for a carbon-constrained future. The report documented results from 97 companies. The aim of the report was to help companies make use of the disclosures as reference points for future carbon markets and regulations relating to reporting requirements. Results of the survey demonstrated that Canada's low-carbon and high-carbon impact sectors have implemented several significant initiatives and best practices for operations. However, widespread engagement in a comprehensive manner has yet to be achieved. Many respondents were in the process of developing a more balanced risk-opportunity agenda in relation to climate change, and nearly half of all respondents have implemented governance arrangements or personal incentives in both both the high-carbon and low-carbon impact sectors. 5 tabs., 26 figs.

    Full Text Available Corporate carbon disclosures have become increasingly commonplace and are often presented as a useful voluntary mechanism for internal and external decision making. The production of the data is said to assistcorporations position themselves strategically in terms of the carbon risks and opportunities they may face. External to the firm, carbon disclosures hold the promise of assisting capital allocation decisions that are ‘carbon responsible’. It is claimed that the process of disclosure can sensitise the market to globalenvironmental problems such as climate change. In order to consider these claims, the broad purpose of this paper is to question whether the voluntary information that is produced can live up to its expectations and provide a meaningful basis for climate change related decision making. To that end, this exploratory studyexamines the carbon disclosures of Australasian mining companies over three years in compliance with a voluntary carbon disclosure regime – the Carbon Disclosure Project (CDP – and assesses those disclosureswith respect to comparability, an important criterion for information usefulness.

    The risks of climate change have shifted from the field of scientific debate to the front lines of investment risk management. This report was based on submissions received from the most valuable corporations listed on the Toronto Stock Exchange. The report was developed by the Carbon Disclosure Project (CDP) and described steps currently being taken by companies to address the challenge of climate change. Eighty-eight per cent of respondents to the survey indicated that climate change presented business risks, while a further 86 per cent suggested that climate change offered increased opportunities. Although the gap between uptake of greenhouse gas (GHG) management and corporate risk awareness has now narrowed, many companies continue to disregard the CDP investor request or provide only limited information in their responses. In this survey, important financial data such as abatement costs, contingent emissions liabilities, and revenue projections were mostly absent from company responses. A climate disclosure leadership index was presented which measured the quality of company disclosures to the CDP5 information request. Sixteen climate disclosure leaders were identified using the index. A continued lack of clear regulations was cited by respondents as a significant impediment to the implementation of a carbon emissions reduction strategy. It was concluded that only 10 per cent of respondents have undertaken a climate change risk assessment. 15 figs

    This study assesses the effectiveness of two types information disclosure programs – state-based mandatory carbon reporting programs and the voluntary Carbon Disclosure Project, which uses investor pressure to push firms to disclose carbon emissions and carbon management strategies. I match firms in each program to control groups of firms that have not participated in each program. Using panel data methods and a difference in differences specification, I measure the impact of each program on plant-level carbon emissions, plant-level carbon intensity, and plant level output. I find that neither program has generated an impact on plant-level carbon emissions, emissions intensity, or output. Placing this study in contrast with others that demonstrate improvements from mandatory information disclosure, these results suggest that how information is reported to stakeholders has important implications for program effectiveness. - Highlights: ► This article evaluates the Carbon Disclosure Project and state carbon reporting requirements. ► Evaluation is conducted with propensity score matching and difference-in-differences. ► State Disclosure Programs fail to lead power plants to reduce carbon dioxide emissions. ► The Carbon Disclosure Project leads to decreases in carbon emissions and electricity output. ► Information disclosure and transparency may be important part of policy mix but have limitations

    The Conference Board of Canada carried out the Canadian component of the fourth annual Carbon Disclosure Project (CDP). Climate change is a topical issue for investors and financial institutions such as pension funds, asset management firms, banks and insurance companies that want to assess the carbon exposure and risk profiles of their investment. This report outlined recent climate-change developments in Canada and examined the state of disclosure of greenhouse gas (GHG) emissions of 280 Canadian companies and the implications for investors and corporations. In February 2006, on behalf of its 225 signatory investors, CDP requested information on corporate risks and opportunities associated with climate change from more than 2,000 companies globally. This report described the steps that respondent companies are taking to address climate change. A methodology was also presented to guide investors who want to determine a company's net carbon risk. It was noted that although awareness of the risks and opportunities posed by climate change has grown significantly among investors, it has not translated into widespread planning and action by Canada's largest companies. It was emphasized that if the negative impacts of climate change are to be avoided, investors will have to put CDP data to work. The $31.5 trillion in assets behind CDP4 includes $1 trillion by Canadian-based investors, a significant increase over the previous report. Sixty-three per cent of respondents provided data on annual GHG emissions. However, different measuring and reporting approaches made it difficult for investors to compare company emission profiles. The response from Canadian companies showed that large companies are responding to investor interests, particularly gas and electrical utilities and other carbon intensive companies in the forest products, petroleum and mining sectors. Canada compared well to the response rates of other jurisdictions, but forward-looking financial and

    The Carbon Disclosure Project (CDP) is an independent not-for-profit organisation aiming to create a lasting relationship between shareholders and corporations regarding the implications for shareholder value and commercial operations presented by climate change. Its goal is to facilitate a dialogue, supported by quality information, from which a rational response to climate change will emerge. Over 7 years CDP has become the gold standard for carbon disclosure methodology and process. CDP4 finds that the global investment and corporate communities have made great strides in their understanding of climate change and its competitive and financial implications, and the measurement of these implications. However, awareness and measurement are not translating into sufficient management and activity in the context of the climate change challenge. (A.L.B.)

    The purpose of this research were to test empirically the relationship of Volume of Carbon emission, Carbon Management Practice disclosure and Carbon disclosure emission with firm value, especially in Indonesia as developing Country. This research using data from Indonesian sustainability Award in 2013-2015. The instrument of this research was adapted from CDP Questionnaires to score the disclosure of Carbon Management Practice. While the carbon emission disclosure instrument was dummy variable. For volume of carbon emission, this research used the quantity or volume of carbon reported in sustainability reporting. We find that Volume of carbon emission was not related to Firm value. Also Carbon disclosure Emission does not have relationship with Firm value. Both hypotheses were not consistent with [8] which was doing their research in Developed Country. While Carbon Management Practice Disclosure, using CDP Questionnaires, has positive relationship with Firm value. The conclusion is developing country as resource constraint need to be motivated to report and disclose carbon emission from voluntary reporting to mandatory by regulation from government, not just only for high sensitive industry but also low sensitive industry. Then developing country which has resource constraint need to have more proactive strategy to prevent carbon emission instead of reducing carbon emission.

    Climate change mitigation in developing economies is a balancing act, between economic development and environmental sustainability. The need for market friendly determinants for low carbon economy, without compromising economic development is of essence. The aim of the study is to determine market friendly factors, which motivates voluntary carbon information disclosure, in the real estate industry. The study modeled economic factor with three variables and financial market factor with three variables against voluntary carbon information disclosure in the real estate industry. Structural equation modeling was used for the modeling and content analysis was used to collect data on the level of voluntary carbon information disclosure, from 2013 annual reports of 126 real estate sector companies listed in the Kuala Lumpur Stock Exchange (KLSE). The model achieved a good fit, and was acceptable prediction. The results show that financial market factor has a significant predictive influence on voluntary carbon disclosure. The application of the result is that financial market factor is has a significantly positive influence on companies’ willingness to make voluntary carbon disclosure in the real estate industry. The result may be limited to the real estate industry that is highly leveraged on syndicated fund.

    Global warming has consequences on the environment and economy; this led to the establishment of United Nation Framework Convention on Climate Change (UNFCCC) and the Kyoto Protocol. These two agreements were to reduce greenhouse gases (GHG) emissions which are responsible for climate change and global warming. Developing countries under the protocol are not obligated to reduce or disclosure GHG emission, so their participation in the protocol is on voluntary mitigation bases. This study intends to examine economic factors that influence voluntary carbon disclosure in the property sub-sector of developing countries based on annual report of listed property companies in Malaysia. Signaling theory addresses the problem of information asymmetry in the society. Disclosure is an effective tool to overcome information imbalance among different market participants. The study hypothesizes that the economic factors that influence voluntary carbon information disclosure in developing countries are: [1] the company's size; this is because a large-sized company have more resources to cover the cost of reducing pollution. [2] The company's gearing status; where there is no sufficient information disclosure in a highly geared company will result to an increased agency cost. [3] Profitability; profits grants companies a pool of resources for mitigation activities and environmental reporting. Also, carbon disclosure acts as a means for achieving public confidence and legitimacy. [4] Liquidity: Companies that are highly liquid will disclosure more information to distinguish themselves from other companies that are less liquidity. This is correlated to environmental disclosure. [5] Financial slack affects companies’ ability to participate in green technology projects that enable a reduction in emission.

    By using Shanghai and Shenzhen A-share listed companies in heavy polluting industry as research object from 2009 to 2014, this paper examines the relationship between media reporting, carbon information disclosure, and the cost of equity financing. The results show that media reporting can improve the quality of carbon information disclosure, and carbon information disclosure level is negatively associated with the cost of equity financing. This study also finds that financial carbon information disclosure and non-financial carbon information disclosure have significant negative relationship with the cost of equity financing respectively. Moreover, this paper shows that media reporting can strengthen the relationship between carbon information disclosure and the cost of equity financing.

    Corporate real estate management holds the tent that risk which is not understood cannot be measured or managed. The effect of global warming on real estate investment and need for climate change mitigation through disclosures by companies of carbon emission information has becomes a sine-qua-non for the management of companies' carbon footprint and reducing its overall effect on global warming. This study applied the structural equation modeling technique to determine the determinants influencing Carbon Disclosure in Real Estate Companies in a developing economy. The analysis was based on 2013 annual reports of 126 property sector companies listed in Malaysia stock exchange market. The model was validated through convergent validity, discriminant validity, composite reliability and goodness of fit. The result reveals that social and financial market were critical determinant factors for carbon disclosure while the economic and institutional factors did not achieve significant effect on voluntary carbon disclosure. The result is consistent with legitimacy theory and agency theories. The implication of this finding is that increase in public education and awareness will enhance community demand for disclosure from companies and they will increase level of disclosure; also as financial institutions consider sustainability practice as a viable investment and term for credit financing, companies will be motivated to increase disclosure.

    Full Text Available The main purpose of this study is to examine the relationship between voluntary disclosure and cost of capital by exploring the impact of voluntary carbon emission disclosure (VCED on the firm’s weighted-average cost of capital. A carbon disclosure index is used to evaluate the quality of carbon emission disclosure in 2013 and 2014 annual reports of 247 Malaysian public listed companies. By using content analysis, the result highlights a significant increase in the level and quality of carbon emission disclosure practice from 2013 to 2014. In addition, the finding from regression analysis indicates insignificant relationship between VCED quality and weighted-average cost of capital. Overall, our findings suggest that the carbon emission disclosure is still low, as such, the quality of VCED do not have an impact on firm’s cost of capital. The results of the study allow the government to measure progress toward achieving its target to reduce carbon emission and will add weight to the call by accounting regulation body such as Malaysian Accounting Standard Board for a specific standard on carbon reporting.

    Full Text Available Purpose: Drawing on asymmetric information and stakeholder theories, this paper investigates two mechanisms, namely market liquidity and cost of equity capital, by which the carbon information disclosure of enterprises can benefit their value creation. Design/methodology/approach: In this research, web crawler technology is employed to study the link between carbon information disclosure and enterprises value creation?and the carbon information data are provided by all companies listed in Chinese A-share market Findings: The results show that carbon information disclosure have significant positive influence on enterprise value creation, which is embodied in the relationship between carbon information disclosure quantity, depth and enterprise value creation, and market liquidity and cost of equity capital play partially mediating role in it, while the influence of carbon information disclosure quality and concentration on enterprise value creation are not significant in statistics. Research limitations/implications: This paper explains the influence path and mechanism between carbon information disclosure and enterprise value creation deeply, answers the question of whether carbon information disclosure affects enterprise value creation or not in China. Practical implications: This paper finds that carbon information disclosure contributes positively to enterprise value creation suggests that managers can reap more financial benefits by disclosing more carbon information and investing carbon emissions management. So, managers in the enterprises should strengthen the management of carbon information disclosure behavior. Originality/value: The paper gives a different perspective on the influence of carbon information disclosure on enterprise value creation, and suggests a new direction to understand carbon information disclosure behavior.

    Certain patients, through projective identification and splitting mechanisms, test the boundaries of the analytic situation. These patients are usually experiencing overwhelming paranoid-schizoid anxieties and view the object as ruthless and persecutory. Using a Kleinian perspective, the author advocates greater analytic flexibility with these difficult patients who seem unable to use the standard analytic environment. The concept of self-disclosure is examined, and the author discusses certain technical situations where self-disclosure may be helpful.(The Journal of Psychotherapy Practice and Research 1999; 8:225–233) PMID:10413442

    In 1989, radioactive-contaminated metal at the Rocky Flats Plant (RFP) was cleaned using a solvent paint stripper (Methylene chloride). One-third of the radioactive material was able to be recycled; two-thirds went to the scrap pile as low-level mixed waste. In addition, waste solvent solutions also required disposal. Not only was this an inefficient process, it was later prohibited by the Resource Conservation and Recovery Act (RCRA), 40 CFR 268. A better way of doing business was needed. In the search for a solution to this situation, it was decided to study the advantages of using a new technology - pelletized carbon dioxide cleaning. A proof of principle demonstration occurred in December 1990 to test whether such a system could clean radioactive-contaminated metal. The proof of principle demonstration was expanded in June 1992 with a pilot project. The purpose of the pilot project was three fold: (1) to clean metal so that it can satisfy free release criteria for residual radioactive contamination at the Rocky Flats Plant (RFP); (2) to compare two different carbon dioxide cleaning systems; and (3) to determine the cost-effectiveness of decontamination process in a production situation and compare the cost of shipping the metal off site for waste disposal. The pilot project was completed in August 1993. The results of the pilot project were: (1) 90% of those items which were decontaminated, successfully met the free release criteria , (2) the Alpheus Model 250 was selected to be used on plantsite and (3) the break even cost of decontaminating the metal vs shipping the contaminated material offsite for disposal was a cleaning rate of 90 pounds per hour, which was easily achieved

    The potential for carbon sequestration at relatively shallow depths was investigated at four power plant sites in Missouri. Exploratory boreholes were cored through the Davis Shale confining layer into the St. Francois aquifer (Lamotte Sandstone and Bonneterre Formation). Precambrian basement contact ranged from 654.4 meters at the John Twitty Energy Center in Southwest Missouri to over 1100 meters near the Sioux Power Plant in St. Charles County. Investigations at the John Twitty Energy Center included 3D seismic reflection surveys, downhole geophysical logging and pressure testing, and laboratory analysis of rock core and water samples. Plans to perform injectivity tests at the John Twitty Energy Center, using food grade CO{sub 2}, had to be abandoned when the isolated aquifer was found to have very low dissolved solids content. Investigations at the Sioux Plant and Thomas Hill Energy Center in Randolph County found suitably saline conditions in the St. Francois. A fourth borehole in Platte County was discontinued before reaching the aquifer. Laboratory analyses of rock core and water samples indicate that the St. Charles and Randolph County sites could have storage potentials worthy of further study. The report suggests additional Missouri areas for further investigation as well.

    This Topical Report addresses accomplishments achieved during Phase 2b of the SkyMine® Carbon Mineralization Pilot Project. The primary objectives of this project are to design, construct, and operate a system to capture CO2 from a slipstream of flue gas from a commercial coal-fired cement kiln, convert that CO2 to products having commercial value (i.e., beneficial use), show the economic viability of the CO2 capture and conversion process, and thereby advance the technology to the point of readiness for commercial scale demonstration and deployment. The overall process is carbon negative, resulting in mineralization of CO2 that would otherwise be released into the atmosphere. The project will also substantiate market opportunities for the technology by sales of chemicals into existing markets, and identify opportunities to improve technology performance and reduce costs at the commercial scale. The project is being conducted in two phases. The primary objectives of Phase 1 were to evaluate proven SkyMine® process chemistry for commercial pilot-scale operation and complete the preliminary design for the pilot plant to be built and operated in Phase 2, complete a NEPA evaluation, and develop a comprehensive carbon life cycle analysis. The objective of Phase 2b was to build the pilot plant to be operated and tested in Phase 2c.

The primary objectives of this project are to design, construct, and operate a system to capture CO{sub 2} from a slipstream of flue gas from a commercial coal-fired cement kiln, convert that CO{sub 2} to products having commercial value (i.e., beneficial use), show the economic viability of the CO{sub 2} capture and conversion process, and thereby advance the technology to a point of readiness for commercial scale demonstration and proliferation. The project will also substantiate market opportunities for the technology by sales of chemicals into existing markets, and identify opportunities to improve technology performance and reduce costs at commercial scale. The primary objectives of Phase 1 of the project were to elaborate proven SkyMine{reg_sign} process chemistry to commercial pilot-scale operation and complete the preliminary design ('Reference Plant Design') for the pilot plant to be built and operated in Phase 2. Additionally, during Phase 1, information necessary to inform a DOE determination regarding NEPA requirements for the project was developed, and a comprehensive carbon lifecycle analysis was completed. These items were included in the formal application for funding under Phase 2. All Phase 1 objectives were successfully met on schedule and within budget.

The 2013 annual reporting of each company were analyzed consonants to the IIRC's framework using qualitative analysis. Categories were created for adherence of information provided by companies and applied content analysis for this purpose. Results suggest that the framework, although not being adopted integrally by the companies, was used as guide for their disclosure practices. Among other observed results for each of framework topics, BRF S.A, CPFL Energia and Itaú Unibanco disclosure practices featured as examples of adherence for the IIRC model and the inherent principles integrated in the report.

    The aim of this DTI project is to establish good quality plant and rig data to demonstrate the effect of changing coal fineness on carbon burnout in a controlled manner, which can then be used to support computational fluid dynamics (CFD) and engineering models of the process. The modelling elements of the project were completed by Mitsui Babcock Energy Ltd., and validated using the data produced by the other partners. The full scale plant trials were successfully completed at Powergen's Kingsnorth Power Station and a full set of tests were also completed on Powergen's CTF. During these test both carbon-in-ash and NOx levels were seen to increase with increasing fuel particle size. Laboratory analysis of fly ash produced during the plant and rig trials revealed that only small differences in char morphology and reactivity could be detected in samples produced under significantly different operating conditions. Thermo Gravimetric Analysis was also undertaken on a range of PF size fractions collected form mills operating at different conditions. 3 refs., 13 figs., 1 tab.

    Literature on HIV status disclosure among persons living with HIV/AIDS (PLWHA) is dominated by research on the rates, barriers and consequences of disclosure to sexual partners, because of the assumed preventive health benefits of partner disclosure. Disclosure of HIV status can lead to an increase in social support and other positive psychosocial outcomes for PLWHA, but disclosure can also be associated with negative social outcomes including stigma, discrimination, and violence. The purpose of this article is to describe the HIV status disclosure narratives of PLWHA living in South Africa. Thirty in-depth interviews were conducted with 13 PLWHA (11 women, 2 men) over a three-year period. We explored disclosure narratives of the PLWHA through questions about who they chose to disclose to, how they disclosed to these individuals, and how these individuals reacted. Narratives focused on disclosure to family members and contained relatively little discussion of disclosure to sexual partners. Participants often disclosed first to one trusted family member, and news of the diagnosis remained with this person for a long period of time, prior to sharing with others. This family member helped the PLWHA cope with the news of their diagnosis and prepared them to disclose to others. Disclosure to one's partner was motivated primarily by a desire to encourage partners to test for HIV. Two participants described overtly negative reactions from a partner upon disclosure, and none of the PLWHA in this sample described very supportive relationships with their partners after disclosure. The critical role that family members played in the narratives of these PLWHA emphasizes the need for a greater focus on disclosure to families for social support in HIV counseling protocols.

    Carbon-14 is a key radionuclide in the assessment of the safety of underground geological disposal facilities for radioactive wastes. It is possible for carbon-14 to be released from waste packages in a variety of chemical forms, both organic and inorganic, and as dissolved or gaseous species The EC CAST (CArbon-14 Source Term) project aims to develop understanding of the generation and release of carbon-14 from radioactive waste materials under conditions relevant to packaging and disposal. It focuses on the release of carbon-14 from irradiated metals (steels and zirconium alloys), from irradiated graphite and from spent ion-exchange resins. The CAST consortium brings together 33 partners. CAST commenced in October 2013 and this paper describes progress to March 2015. The main activities during this period were reviews of the current status of knowledge, the identification and acquisition of suitable samples and the design of experiments and analytical procedures.

    Full Text Available The globe's first carbon projects were designed and implemented approximately 20 years ago following scientific insights that emissions of greenhouse gases needed to be mitigated. Visible in some of these early projects were the important aspects of social governance and local benefit sharing. The projects promised to be a panacea to environmental, social and economic problems in remote rural areas of developing countries. However, it took another decade before a wave of hundreds of carbon projects were launched. Many of the projects were offered under the mechanism of REDD+ (Reducing Emissions from Deforestation and forest Degradation, plus the role of conservation, sustainable forest management and carbon enhancement, as well as under a variety of voluntary schemes and national programs, public-private partnerships, and forestry-based investment initiatives. As decision-makers prepare the Conference of the Parties of the United Nations Framework Convention on Climatic Change in Paris (COP21, Earthscan has released a book entitled `Carbon conflicts and forest landscapes in Africa', edited by Melissa Leach and Ian Scoones. According to the editors, the focus of the book is on what happens on the ground when carbon forestry projects arrive, what types of projects work, and, equally important, what doesn’t work.

  15. Strategizing Carbon-Neutral Mines: A Case for Pilot Projects

    Directory of Open Access Journals (Sweden)

    Ian M. Power

    2014-05-01

    Full Text Available Ultramafic and mafic mine tailings are a valuable feedstock for carbon mineralization that should be used to offset carbon emissions generated by the mining industry. Although passive carbonation is occurring at the abandoned Clinton Creek asbestos mine, and the active Diavik diamond and Mount Keith nickel mines, there remains untapped potential for sequestering CO2 within these mine wastes. There is the potential to accelerate carbonation to create economically viable, large-scale CO2 fixation technologies that can operate at near-surface temperature and atmospheric pressure. We review several relevant acceleration strategies including: bioleaching of magnesium silicates; increasing the supply of CO2 via heterotrophic oxidation of waste organics; and biologically induced carbonate precipitation, as well as enhancing passive carbonation through tailings management practices and use of CO2 point sources. Scenarios for pilot scale projects are proposed with the aim of moving towards carbon-neutral mines. A financial incentive is necessary to encourage the development of these strategies. We recommend the use of a dynamic real options pricing approach, instead of traditional discounted cash-flow approaches, because it reflects the inherent value in managerial flexibility to adapt and capitalize on favorable future opportunities in the highly volatile carbon market.

    This study investigates commonalities and differences in projected land biosphere carbon storage among climate change projections derived from one emission scenario by five different general circulation models (GCMs). Carbon storage is studied using a global biogeochemical process model of vegetation and soil that includes dynamic treatment of changes in vegetation composition, a recently enhanced version of the Lund-Potsdam-Jena Dynamic Global Vegetation Model (LPJ-DGVM). Uncertainty in future terrestrial carbon storage due to differences in the climate projections is large. Changes by the end of the century range from -106 to +201 PgC, thus, even the sign of the response whether source or sink, is uncertain. Three out of five climate projections produce a land carbon source by the year 2100, one is approximately neutral and one a sink. A regional breakdown shows some robust qualitative features. Large areas of the boreal forest are shown as a future CO2 source, while a sink appears in the arctic. The sign of the response in tropical and sub-tropical ecosystems differs among models, due to the large variations in simulated precipitation patterns. The largest uncertainty is in the response of tropical rainforests of South America and Central Africa.

    In this project we focused on several aspects of technology development that advances the formation of an integrated biorefinery. These focus areas include: [ 1] pretreatment of biomass to enhance quality of products from thermochemical conversion; [2] characterization of and development of coproduct uses; [3] advancement in fermentation of lignocellulosics and particularly C5 and C6 sugars simultaneously, and [ 4] development of algal biomass as a potential substrate for the biorefinery. These advancements are intended to provide a diverse set of product choices within the biorefinery, thus improving the cost effectiveness of the system. Technical effectiveness was demonstrated in the thermochemical product quality in the form of lower tar production, simultaneous of use of multiple sugars in fermentation, use ofbiochar in environmental (ammonia adsorption) and agricultural applications, and production of algal biomass in wastewaters. Economic feasibility of algal biomass production systems seems attractive, relative to the other options. However, further optimization in all paths, and testing/demonstration at larger scales are required to fully understand the economic viabilities. The coproducts provide a clear picture that multiple streams of value can be generated within an integrated biorefinery, and these include fuels and products.

    Rehabilitation of degraded forest land throughimplementation of carbon sink projects can increase terrestrial carbonstock. However, carbon emissions outside the project boundary, which iscommonly referred to as leakage, may reduce or negate the sequestrationbenefits. This study assessed leakage from carbon sink projects thatcould potentially be implemented in the study area comprised of elevensub-districts in the Batanghari District, Jambi Province, Sumatra,Indonesia. The study estimates the probability of a given land use/coverbeing converted into other uses/cover, by applying a logit model. Thepredictor variables were: proximity to the center of the land use area,distance to transportation channel (road or river), area of agriculturalland, unemployment (number of job seekers), job opportunities, populationdensity and income. Leakage was estimated by analyzing with and withoutcarbon sink projects scenarios. Most of the predictors were estimated asbeing significant in their contribution to land use cover change. Theresults of the analysis show that leakage in the study area can be largeenough to more than offset the project's carbon sequestration benefitsduring the period 2002-2012. However, leakage results are very sensitiveto changes of carbon density of the land uses in the study area. Byreducing C-density of lowland and hill forest by about 10 percent for thebaseline scenario, the leakage becomes positive. Further data collectionand refinement is therefore required. Nevertheless, this study hasdemonstrated that regional analysis is a useful approach to assessleakage.

    The Final Technical documents all work performed during the award period on the Mountaineer Commercial Scale Carbon Capture & Storage project. This report presents the findings and conclusions produced as a consequence of this work. As identified in the Cooperative Agreement DE-FE0002673, AEP's objective of the Mountaineer Commercial Scale Carbon Capture and Storage (MT CCS II) project is to design, build and operate a commercial scale carbon capture and storage (CCS) system capable of treating a nominal 235 MWe slip stream of flue gas from the outlet duct of the Flue Gas Desulfurization (FGD) system at AEP's Mountaineer Power Plant (Mountaineer Plant), a 1300 MWe coal-fired generating station in New Haven, WV. The CCS system is designed to capture 90% of the CO{sub 2} from the incoming flue gas using the Alstom Chilled Ammonia Process (CAP) and compress, transport, inject and store 1.5 million tonnes per year of the captured CO{sub 2} in deep saline reservoirs. Specific Project Objectives include: (1) Achieve a minimum of 90% carbon capture efficiency during steady-state operations; (2) Demonstrate progress toward capture and storage at less than a 35% increase in cost of electricity (COE); (3) Store CO{sub 2} at a rate of 1.5 million tonnes per year in deep saline reservoirs; and (4) Demonstrate commercial technology readiness of the integrated CO{sub 2} capture and storage system.

    Road infrastructure in Indonesia is mainly dominated by flexible pavement type. Its construction process, however, has raised concerns in terms of its environment impacts. This study aims to track and measure the carbon footprint of flexible pavement. The objectives are to map the construction process in relation to greenhouse gas (GHG) emissions, to quantify them in terms of carbon dioxide equivalents (CO2e) as generated by the process of production and transportation of raw materials, and the operation of plant off-site and on-site project. Data collection was done by having site observations and interviews with project stakeholders. The results show a total emissions of 70.888 tonnes CO2e, consisting of 34.248 tonnes CO2e (48.31%) off-site activities and 36.640 tonnes CO2e (51.687%) on-site activities. The two highest CO2e emissions were generated by the use of plant for asphalt concrete laying activities accounted 34.827 tonnes CO2e (49.130%), and material transportation accounted 24.921 (35.155%). These findings provide a new perspective of the carbon footprint in flexible pavement and suggest the urgent need for the use of more efficient and environmentally friendly plant in construction process as it shows the most significant contribution on the CO2e. This study provides valuable understanding on the environmental impact of typical flexible pavement projects in Indonesia, and further can be used for developing green road framework.

  3. Carbon gains by conservation projects overbalance carbon losses by degradation in China's karst ecoregions

    China's ecological restoration projects are considered as "mega-engineering" activities and the most ambitious afforestation and conservation projects in human history. The highly sensitive and vulnerable karst ecosystem in Southwest China is one of the largest exposed carbonate rock areas (more than 0.54 million km2) in the world. Accelerating desertification has been reported during the last half century, caused by the increasing intensity of human exploitation of natural resources. As a result, vast karst areas (approximately 0.12 million km2) previously covered by vegetation and soil were turned into a rocky landscape. To combat this severe form of land degradation, more than 19 billion USD have been invested in mitigation initiatives since the end of the 1990s. The costs of mega-engineering as a climate change mitigation measure are however only justified if ecosystem properties can be affected at large scales. Here we study the carbon balance of the karst regions of 8 Chinese provinces over four decades, using optical and passive microwave satellite data, supported by statistical data on project implementations. We find that most areas experiencing losses in aboveground biomass carbon are located in areas with a high standing biomass ( 95 Mg C ha-1), whereas areas with a carbon gain are mostly located in regions with a low standing biomass ( 45 Mg C ha-1). However, the overall gains in carbon stocks overbalance the losses, with an average gross loss of -0.8 Pg C and a gross gain of +2.4 Pg C (1980s to 2016), resulting in a net gain of 1.6 Pg C. Areas of carbon gains are widespread and spatially coherent with conservation projects implemented after 2001, whereas areas of carbon losses show that ongoing degradation is still happening in the western parts of the karst regions. We conclude that the impact of conservation projects on the carbon balance of China's karst ecoregions is remarkable, but biomass carbon losses caused by ongoing degradation can not be

    NASA's space-based observations of physical, chemical and biological parameters in the Earth System along with state-of-the-art modeling capabilities provide unique capabilities for analyses of the carbon cycle. The Carbon Monitoring System is developing an exploratory framework for detecting carbon in the environment and its changes, with a view towards contributing to national and international monitoring activities. The Flux-Pilot Project aims to provide a unified view of land-atmosphere and ocean-atmosphere carbon exchange, using observation-constrained models. Central to the project is the application of NASA's satellite observations (especially MODIS), the ACOS retrievals of the JAXA-GOSAT observations, and the "MERRA" meteorological reanalysis produced with GEOS-S. With a primary objective of estimating uncertainty in computed fluxes, two land- and two ocean-systems are run for 2009-2010 and compared with existing flux estimates. An transport model is used to evaluate simulated CO2 concentrations with in-situ and space-based observations, in order to assess the realism of the fluxes and how uncertainties in fluxes propagate into atmospheric concentrations that can be more readily evaluated. Finally, the atmospheric partial CO2 columns observed from space are inverted to give new estimates of surface fluxes, which are evaluated using the bottom-up estimates and independent datasets. The focus of this presentation will be on the science goals and current achievements of the pilot project, with emphasis on how policy-relevant questions help focus the scientific direction. Examples include the issue of what spatio-temporal resolution of fluxes can be detected from polar-orbiting satellites and whether it is possible to use space-based observations to separate contributions to atmospheric concentrations of (say) fossil-fuel and biological activity

    Full Text Available On the last decades the accounting system haven‘t been able to follow the dynamics of the economic systems generated by the globalization process. In order to reduce the lag between the demand of financial information and the offer of financial information, IASB has started numerous initiatives aiming the increase on the quality of the financial information. Among the current list of current IASB major projects there is also the project of revising the actual conceptual framework for financial reporting. This study is designed to give some directions that will be considered on the exposure draft of this project, analyzing the comment letters submitted by the members of ASAF and the Big4 as well. The study reveals the increasing importance the preparers and users give to the disclosures included on the notes to the primary financial statements. Moreover, on this study we emphasize several challenges that IASB has to face on issuing the exposure draft for this important project. Some of the main challenges refer to the narrow scope of the financial statements, the criteria used on classification, aggregation and offsetting, or the use of the materiality concept

    The LandCarbon project is assessing potential carbon pools and greenhouse gas fluxes under various scenarios and land management regimes to provide information to support the formulation of policies governing climate change mitigation, adaptation and land management strategies. The project is unique in that spatially explicit maps of annual land cover and land-use change are created at the 250-meter pixel resolution. The project uses vast amounts of data as input to the models, including satellite, climate, land cover, soil, and land management data. Management data have been obtained from the U.S. Department of Agriculture (USDA) National Agricultural Statistics Service (NASS) and USDA Economic Research Service (ERS) that provides information regarding crop type, crop harvesting, manure, fertilizer, tillage, and cover crop (U.S. Department of Agriculture, 2011a, b, c). The LandCarbon team queried the USDA databases to pull historic crop-related management data relative to the needs of the project. The data obtained was in table form with the County or State Federal Information Processing Standard (FIPS) and the year as the primary and secondary keys. Future projections were generated for the A1B, A2, B1, and B2 Intergovernmental Panel on Climate Change (IPCC) Special Report on Emissions Scenarios (SRES) scenarios using the historic data values along with coefficients generated by the project. The PBL Netherlands Environmental Assessment Agency (PBL) Integrated Model to Assess the Global Environment (IMAGE) modeling framework (Integrated Model to Assess the Global Environment, 2006) was used to develop coefficients for each IPCC SRES scenario, which were applied to the historic management data to produce future land management practice projections. The LandCarbon project developed algorithms for deriving gridded data, using these tabular management data products as input.

    2018-03-01

    Future projections of east Amazonian precipitation indicate drying, but they are uncertain and poorly understood. In this study we analyze the Amazonian precipitation response to individual atmospheric forcings using a number of global climate models. Black carbon is found to drive reduced precipitation over the Amazon due to temperature-driven circulation changes, but the magnitude is uncertain. CO2 drives reductions in precipitation concentrated in the east, mainly due to a robustly negative, but highly variable in magnitude, fast response. We find that the physiological effect of CO2 on plant stomata is the dominant driver of the fast response due to reduced latent heating and also contributes to the large model spread. Using a simple model, we show that CO2 physiological effects dominate future multimodel mean precipitation projections over the Amazon. However, in individual models temperature-driven changes can be large, but due to little agreement, they largely cancel out in the model mean.

    Carbon and financial accounting of projects in the Land Use, Land-Use Change and Forestry sector is a topic of hot debate. Large uncertainty remains concerning the carbon dynamics, the way they should be accounted and the cost efficiency of the projects. Part of the uncertainty can be alleviated by standardisation and transparency of reporting methods. For this reason we further developed CO2FIX, a forest ecosystem carbon model, with modules for carbon and financial accounting. The model is a...

    The Rapid Carbon Assessment (RaCA) project was undertaken to estimate regional soil organic carbon (SOC) stocks across the conterminous United States (CONUS) as a one-time event. Sample locations were selected randomly using the NRI (National Resource Inventory) sampling framework covering all areas in CONUS with SSURGO certified maps as of Dec 2012. Within each of 17 regions, sites were selected by a combination of soil and land use/cover groups (LUGR). At each of more than 6,000 sites five pedons were described and sampled to a depth of 100cm (one central and 4 satellites 30m in each cardinal direction). There were 144,833 samples described from 32,084 pedons at 6, 017 sites. A combination of measurement and modeled bulk density was used for all samples. A visible near-infrared (VNIR) spectrophotometer was used to scan each sample for prediction of soil carbon contents. The samples of each central pedon were analyzed by the Kellogg Soil Survey Laboratory for combustion carbon and calcimeter inorganic carbon. SOC stocks were calculated for each pedon using a standard fixed depth technique to depths of 5, 30 and 100cm. Pedon SOC stocks were transformed to better approach normality before LUGR, regional and land use/cover summaries were calculated. The values reported are geometric means. A detailed spatial map can be produced using LUGR mean assignment to correlated pixels. LUGR values range from 1 to 3,000 Mg ha-1. While some artifacts are visible due to the stratified nature of sampling and extrapolation, the predictions are generally smooth and highlight some distinct geomorphic features including the sandhills in the Great Plains in the central US, mountainous regions in the West and coastal wetlands in the East. Regional averages range from 46 Mg ha-1 in the desert Southwest to 182 Mg ha-1 in the Northeast. Regional trends correlate to climate variables such as precipitation and potential evapotranspiration. While land use/cover classes vary in mean values

    questions: 1. Do model results and observations show consistent spatial patterns in response to the 2002 drought? From measurements and model, can we infer what processes were affected by the 2002 drought? 2. What is the spatial pattern and magnitude of interannual variation in carbon sources and sinks? What are the components of carbon fluxes and pools that contribute to this variation? 3. What are the magnitudes and spatial distribution of carbon sources and sinks, and their uncertainties during the period 2000-2005? Examining and comparing results of inverse and forward model simulations with each other and with suitable benchmark spatial measurements help evaluate model strengths/weaknesses and utility, thereby providing multiple views of spatial and temporal patterns of fluxes, leading to better understandings of processes involved, and providing an improved basis for making projections.

    2013-09-01

    As with other large healthcare organizations, medical adverse events at the Department of Veterans Affairs (VA) facilities can expose patients to unforeseen negative risks. VHA leadership recognizes that properly handled disclosure of adverse events can minimize potential harm to patients and negative consequences for the effective functioning of the organization. The work documented here seeks to help improve the disclosure process by situating it within the broader theoretical framework of issues management, and to identify opportunities for process improvement through modeling disclosure and reactions to disclosure. The computational model will allow a variety of disclosure actions to be tested across a range of incident scenarios. Our conceptual model will be refined in collaboration with domain experts, especially by continuing to draw on insights from VA Study of the Communication of Adverse Large-Scale Events (SCALE) project researchers.

    Full Text Available Forest plantation may contribute economically and socially as a provider of wood raw materials for industry and providing jobs for local people. In addition, forest plantation may also contribute as watershed protection and carbon sequestration. Projects on carbon sequestration from plantation forest can be conducted in two types: (1 afforestation and (2 lengthening forest rotation. One of the potential carbon markets operationalized in the field is voluntary market with Verified Carbon Standard mechanism. This study aimed to analyze the optimal rotations of gmelina forests on two carbon projects: lengthening rotation and afforestation. The method used in this study was by using Hartman model ( i.e. Faustmann by maximizing profit with the revenue source from timber and carbon sequestration project. The results of this study showed that carbon price will affect the optimal rotation for lengthening forest rotation of VCS project. Meanwhile, for VCS afforestation project, carbon price had no effect on the optimal rotation on gmelina forest. The NPV value of afforestation project was relatively higher than that of NPV value of lengthening forest rotation project, since the amount of carbon that can be credited relatively higher in afforestation project.

    The Kyoto Protocol is the first step towards achieving the objectives of the United Nations Framework Convention on Climate Change and aims among others to promote 'the protection and enhancement of carbon sinks and reservoirs'. To encourage afforestation for carbon sequestration a project must be economically viable. This study uses a model to analyse the impact on project viability of a range of carbon monitoring options, international carbon credit value and discount rate, applied to a Pinus radiata afforestation project in New Zealand. Monitoring carbon in conjunction with conventional forest inventory shows the highest return. Long-term average carbon accounting has lower accounting costs, compared to annual and 5 yearly accounting, as monitoring is only required every 5-10 years until the long-term average is attained. In this study we conclude that monitoring soil carbon stocks is not economically feasible using any of the accounting methods, when carbon is valued at US$ 10/t. This conclusion may be relevant to forest carbon sequestration projects elsewhere in the world and suggests care is needed in selecting the appropriate carbon monitoring options to avoid the risk that costs could be higher than any monetary benefits from terrestrial carbon sequestration. This would remove any commercial incentive to afforest for carbon sequestration reasons and severely limit the use of forest sinks as part of any package of measures addressing the ultimate objective of the UNFCCC

    In North America forest and grassland ecosystems play a major role in the carbon cycle. Here we present the latest trends and projections of United States and North American carbon cycle processes, stocks, and flows in the context of interactions with global scale budgets and climate change impacts in managed and unmanaged grassland and forest ecosystems. We describe recent trends in natural and anthropogenic disturbances in these ecosystems as well as the carbon dynamics associated with land use and land cover change. We also highlight carbon management science and tools for informing decisions and opportunities for improving carbon measurements, observations, and projections in forests and grasslands.

    2009-01-01

    This article evaluates the impact of the 2006 compliance event on changes in investors' risk aversion on the European carbon market using the newly available option prices dataset. Thus, we aim at capturing the specific event that occurred on April 2007 as the European Commission disclosed the 2006 verified emissions data. Following the methodology existing for stock indices, we recover empirically risk aversion adjustments on the period 2006-2007 by estimating first the risk-neutral distribution from option prices and second the actual distribution from futures on the European Climate Exchange. Our results show evidence of a dramatic change in the market perception of risk around the 2006 yearly compliance event that has not been assessed yet. (author)

    The present study evaluates a carbon sequestration project for the three plant species in arid and semiarid regions of Iran. Results show that Haloxylon performed appropriately in the carbon sequestration process during the 6 years of the International Carbon Sequestration Project (ICSP). In addition to a high degree of carbon dioxide sequestration, Haloxylon shows high compatibility with severe environmental conditions and low maintenance costs. Financial and economic analysis demonstrated that the ICSP was justified from an economic perspective. The financial assessment showed that net present value (NPV) (US$1,098,022.70), internal rate of return (IRR) (21.53%), and payback period (6 years) were in an acceptable range. The results of the economic analysis suggested an NPV of US$4,407,805.15 and an IRR of 50.63%. Therefore, results of this study suggest that there are sufficient incentives for investors to participate in such kind of Clean Development Mechanism (CDM) projects.

  2. Management of water extracted from carbon sequestration projects

    2011-03-11

    Throughout the past decade, frequent discussions and debates have centered on the geological sequestration of carbon dioxide (CO{sub 2}). For sequestration to have a reasonably positive impact on atmospheric carbon levels, the anticipated volume of CO{sub 2} that would need to be injected is very large (many millions of tons per year). Many stakeholders have expressed concern about elevated formation pressure following the extended injection of CO{sub 2}. The injected CO{sub 2} plume could potentially extend for many kilometers from the injection well. If not properly managed and monitored, the increased formation pressure could stimulate new fractures or enlarge existing natural cracks or faults, so the CO{sub 2} or the brine pushed ahead of the plume could migrate vertically. One possible tool for management of formation pressure would be to extract water already residing in the formation where CO{sub 2} is being stored. The concept is that by removing water from the receiving formations (referred to as 'extracted water' to distinguish it from 'oil and gas produced water'), the pressure gradients caused by injection could be reduced, and additional pore space could be freed up to sequester CO{sub 2}. Such water extraction would occur away from the CO{sub 2} plume to avoid extracting a portion of the sequestered CO{sub 2} along with the formation water. While water extraction would not be a mandatory component of large-scale carbon storage programs, it could provide many benefits, such as reduction of pressure, increased space for CO{sub 2} storage, and potentially, 'plume steering.' Argonne National Laboratory is developing information for the U.S. Department of Energy's (DOE's) National Energy Technology Laboratory (NETL) to evaluate management of extracted water. If water is extracted from geological formations designated to receive injected CO{sub 2} for sequestration, the project operator will need to identify methods

    In many afforestation and reforestation (AR) projects harvesting with stand regeneration forms an integral part of the silvicultural system and satisfies local timber and/or fuelwood demand. Especially clear-cut harvesting will lead to an abrupt and significant reduction of carbon stocks. The smaller the project, the more significant the fluctuations of the carbon stocks may be. In the extreme case a small-scale project could consist of a single forest stand. In such case, all accounted carbon may be removed during a harvesting operation and the time-path of carbon stocks will typically look as in the hypothetical example presented in the report. For the aggregate of many such small-scale projects there will be a constant benefit to the atmosphere during the projects, due to averaging effects.

    National Science Content Standards identify systems as an important unifying concept across the K-12 curriculum. While this standard exists, there is a recognized gap in the ability of students to use a systems thinking approach in their learning. In a similar vein, both popular media as well as some educational curricula move quickly through climate topics to carbon footprint analyses without ever addressing the nature of carbon or the carbon cycle. If students do not gain a concrete understanding of carbon’s role in climate and energy they will not be able to successfully tackle global problems and develop innovative solutions. By participating in the GLOBE Carbon Cycle project, students learn to use a systems thinking approach, while at the same time, gaining a foundation in the carbon cycle and it's relation to climate and energy. Here we present the GLOBE Carbon Cycle project and materials, which incorporate a diverse set of activities geared toward upper middle and high school students with a variety of learning styles. A global carbon cycle adventure story and game let students see the carbon cycle as a complete system, while introducing them to systems thinking concepts including reservoirs, fluxes and equilibrium. Classroom photosynthesis experiments and field measurements of schoolyard vegetation brings the global view to the local level. And the use of computer models at varying levels of complexity (effects on photosynthesis, biomass and carbon storage in global biomes, global carbon cycle) not only reinforces systems concepts and carbon content, but also introduces students to an important scientific tool necessary for understanding climate change.

    The global carbon cycle is a key regulator of the Earth's climate and is central to the normal function of ecological systems. Because rising atmospheric CO2 is the principal cause of climate change, understanding how ecosystems cycle and store carbon has become an extremely important issue. In recent years, the growing importance of the carbon cycle has brought it to the forefront of both science and environmental policy. The need for better scientific understanding has led to establishment of numerous research programs, such as the North American Carbon Program (NACP), which seeks to understand controls on carbon cycling under present and future conditions. Parallel efforts are greatly needed to integrate state-of-the-art science on the carbon cycle and its importance to climate with education and outreach efforts that help prepare society to make sound decisions on energy use, carbon management and climate change adaptation. Here, we present a new effort that joins carbon cycle scientists with the International GLOBE Education program to develop carbon cycle activities for K-12 classrooms. The GLOBE Carbon Cycle project is focused on bringing cutting edge research and research techniques in the field of terrestrial ecosystem carbon cycling into the classroom. Students will collect data about their school field site through existing protocols of phenology, land cover and soils as well as new protocols focused on leaf traits, and ecosystem growth and change. They will also participate in classroom activities to understand carbon cycling in terrestrial ecosystems, these will include plant- a-plant experiments, hands-on demonstrations of various concepts, and analysis of collected data. In addition to the traditional GLOBE experience, students will have the opportunity to integrate their data with emerging and expanding technologies including global and local carbon cycle models and remote sensing toolkits. This program design will allow students to explore research

    2016-07-01

    Full Text Available With the low-carbon economy advocated all over the world, how to use energy reasonably and efficiently in public projects has become a major issue. It has brought many open questions, including which method is more reasonable in evaluating the energy utilization of carbon performance in public projects when the evaluation information is fuzzy; whether an indicator system can be constructed; and which indicators have more impact on carbon performance. This article aims to solve these problems. We propose a new carbon performance evaluation system for energy utilization based on project processes (design, construction, and operation. Fuzzy Analytic Hierarchy Process (FAHP is used to accumulate the indicator weights and cloud model is incorporated when the indicator value is fuzzy. Finally, we apply our indicator system to a case study of the Xiangjiang River project in China, which demonstrates the applicability and efficiency of our method.

    Carbon offset projects through forestation are employed within the emissions trading framework to store carbon. Yet, information about the potential of landscapes to stock carbon, essential to the design of offset projects, is often lacking. Here, based on data on vegetation carbon, climate and soil, we quantify the potential for carbon storage in woody vegetation across tropical Africa. The ability of offset projects to produce co-benefits for ecosystems and people is then quantified. When co-benefits such as biodiversity conservation are considered, the top-ranked sites are sometimes different to sites selected purely for their carbon-stocking potential, although they still possess up to 92% of the latter carbon-stocking potential. This work provides the first continental-scale assessment of which areas may provide the greatest direct and indirect benefits from carbon storage reforestation projects at the smallest costs and risks, providing crucial information for prioritization of investments in carbon storage projects.

    Forest carbon offset project implementation costs, comprised of both production and transaction costs, could present an important barrier to private landowner participation in carbon offset markets. These costs likewise represent a largely undocumented component of forest carbon offset potential. Using a custom spreadsheet model and accounting tool, this study examines the implementation costs of different forest offset project types operating in different forest types under different accounting and sampling methodologies. Sensitivity results are summarized concisely through response surface regression analysis to illustrate the relative effect of project-specific variables on total implementation costs. Results suggest that transaction costs may represent a relatively small percentage of total project implementation costs - generally less than 25% of the total. Results also show that carbon accounting methods, specifically the method used to establish project baseline, may be among the most important factors in driving implementation costs on a per-ton-of-carbon-sequestered basis, dramatically increasing variability in both transaction and production costs. This suggests that accounting could be a large driver in the financial viability of forest offset projects, with transaction costs likely being of largest concern to those projects at the margin.

  11. Historic and projected vehicle use and carbon dioxide emissions

    International Nuclear Information System (INIS)

    1990-01-01

    Data are presented in this chapter that show a decline in total carbon dioxide emissions per vehicle of about 20 between 1970 and 1987. However, it is also shown that the fuel economy gains of the 1970s and early 1980s in many countries have begun to erode. In the US, low fuel prices combined with a failure to strengthen fuel efficiency standards have led to recent declines in new-car fuel efficiency. Even if these trends are reversed carbon dioxide in the transport sector will not be reduced if over all motor vehicle use continues along present lines

  12. Quantitative Decision Making Model for Carbon Reduction in Road Construction Projects Using Green Technologies

    Directory of Open Access Journals (Sweden)

    2015-08-01

    Full Text Available Numerous countries have established policies for reducing greenhouse gas emissions and have suggested goals pertaining to these reductions. To reach the target reduction amounts, studies on the reduction of carbon emissions have been conducted with regard to all stages and processes in construction projects. According to a study on carbon emissions, the carbon emissions generated during the construction stage of road projects account for approximately 76 to 86% of the total carbon emissions, far exceeding the other stages, such as maintenance or demolition. Therefore, this study aims to develop a quantitative decision making model that supports the application of green technologies (GTs to reduce carbon emissions during the construction stage of road construction projects. First, the authors selected environmental soundness, economic feasibility and constructability as the key assessment indices for evaluating 20 GTs. Second, a fuzzy set/qualitative comparative analysis (FS/QCA was used to establish an objective decision-making model for the assessment of both the quantitative and qualitative characteristics of the key indices. To support the developed model, an expert survey was performed to assess the applicability of each GT from a practical perspective, which was verified with a case study using two additional GTs. The proposed model is expected to support practitioners in the application of suitable GTs to road projects and reduce carbon emissions, resulting in better decision making during road construction projects.

    Full Text Available The Malaysian construction industry significantly contributes as an empowerment to its development vision of 2020 by reducing 40% of carbon emission. Moreover, this industry accounts as a threat to the environment, not only in terms of consumption of natural resources but also in emitting million tons of carbon emission annually. In fact, Malaysia is categorized the 30th in the world's ranking in carbon emission level. To mitigate the raise of carbon emission level from the buildings construction, several studies identified some of the effective carbon emission assessment tools for construction projects but it is lack of implementation in Malaysia. The green building index (GBI, Malaysian CIB Report has been introduced to assist the construction stakeholders in reducing the level of carbon emission and the impact of buildings on the environment. This paper presents an analysis of carbon emission from housing projects and office buildings in order to identify and quantify the main sources of carbon emission for each project and it proposes environmental friendly materials as replacement for conventional construction materials to achieve the implementation of sustainability in Malaysia.

  16. Stakeholders of Voluntary Forest Carbon Offset Projects in China: An Empirical Analysis

    Directory of Open Access Journals (Sweden)

    Derong Lin

    2015-01-01

    Full Text Available Climate change is one of the defining challenges facing the planet. Voluntary forest carbon offset project which has the potential to boost forest carbon storage and mitigate global warming has aroused the global concern. The objective of this paper is to model the game situation and analyze the game behaviors of stakeholders of voluntary forest carbon offset projects in China. A stakeholder model and a Power-Benefit Matrix are constructed to analyze the roles, behaviors, and conflicts of stakeholders including farmers, planting entities, communities, government, and China Green Carbon Foundation. The empirical analysis results show that although the stakeholders have diverse interests and different goals, a win-win solution is still possible through their joint participation and compromise in the voluntary forest carbon offset project. A wide governance structure laying emphasis on benefit balance, equality, and information exchanges and being regulated by all stakeholders has been constructed. It facilitates the agreement among the stakeholders with conflicting or different interests. The joint participation of stakeholders in voluntary forest carbon offset projects might change the government-dominated afforestation/reforestation into a market, where all participators including government are encouraged to cooperate with each other to improve the condition of fund shortage and low efficiency.

  17. Assessing the appropriateness of carbon financing for micro-scale projects in terms of capabilities

    Directory of Open Access Journals (Sweden)

    Caitlin Trethewy

    2013-08-01

    Full Text Available Micro-scale development projects are currently underrepresented in global carbon markets. This paper outlines the process of becoming eligible to generate carbon credits and examines some of the barriers that may inhibit access to carbon markets. In particular, it focuses on barriers relating to the capacity and resources of the organisation developing the project. This approach represents a deviation from the standard discourse which has traditionally focused on barriers relating to the availability of up-front finance and the capacity of local public and private sector institutions required to participate in the carbon standard certification process. The paper contains an analysis of the carbon offset project cycle from which follows a discussion of potential capacity- related barriers focusing on time, skills and resources. Recommendations are made as to how these may be overcome with a particular focus on the role of technical organisations in assisting project developers. Completed during 2012 this research comes at an interesting time for global carbon markets as the Kyoto Protocol’s first commitment period ended in 2012 and negotiations have failed to produce and agreement that would commit major emitters to reductions targets from 2013 onward. Despite this, reducing greenhouse gas emissions has gained momentum on the national level and many governments are in the process of formulating and introducing emissions trading schemes.

  18. Carbon Accounting and Cost Estimation in Forestry Projects Using CO2Fix V.3

    2006-01-01

    Carbon and financial accounting of projects in the Land Use, Land-Use Change and Forestry sector is a topic of hot debate. Large uncertainty remains concerning the carbon dynamics, the way they should be accounted and the cost efficiency of the projects. Part of the uncertainty can be alleviated by standardisation and transparency of reporting methods. For this reason we further developed CO2FIX, a forest ecosystem carbon model, with modules for carbon and financial accounting. The model is applied to four cases: (1) Joint implementation afforestation project in Romania, (2) Forest management project in Central Europe, (3) Reduced impact logging possibly under the Clean Development Mechanism (CDM) in the future, and (4) Afforestation with native species under the Clean Development Mechanism. The results show the wide applicability of CO2FIX, from degrading grasslands as baseline cases to multiple cohort forest ecosystems. Also the results show that Forest Management in the European case can generate considerable amounts of carbon emission reductions. Further, the results show that although reduced impact logging is not yet an allowed option under the Clean Development Mechanism, it shows promising results in that it is (1) very cost effective, (2) seems to be able to generate intermediate amounts of credits and (3) seems to us as a project type that is not prone to leakage issues. These results are yet another indication to seriously consider reduced impact logging as an eligible measure under the CDM

    2015-10-01

    There are concerns that Reduced Emissions from Deforestation and forest Degradation (REDD+) may fail to deliver potential biodiversity cobenefits if it is focused on high carbon areas. We explored the spatial overlaps between carbon stocks, biodiversity, projected deforestation threats, and the location of REDD+ projects in Indonesia, a tropical country at the forefront of REDD+ development. For biodiversity, we assembled data on the distribution of terrestrial vertebrates (ranges of amphibians, mammals, birds, reptiles) and plants (species distribution models for 8 families). We then investigated congruence between different measures of biodiversity richness and carbon stocks at the national and subnational scales. Finally, we mapped active REDD+ projects and investigated the carbon density and potential biodiversity richness and modeled deforestation pressures within these forests relative to protected areas and unprotected forests. There was little internal overlap among the different hotspots (richest 10% of cells) of species richness. There was also no consistent spatial congruence between carbon stocks and the biodiversity measures: a weak negative correlation at the national scale masked highly variable and nonlinear relationships island by island. Current REDD+ projects were preferentially located in areas with higher total species richness and threatened species richness but lower carbon densities than protected areas and unprotected forests. Although a quarter of the total area of these REDD+ projects is under relatively high deforestation pressure, the majority of the REDD+ area is not. In Indonesia at least, first-generation REDD+ projects are located where they are likely to deliver biodiversity benefits. However, if REDD+ is to deliver additional gains for climate and biodiversity, projects will need to focus on forests with the highest threat to deforestation, which will have cost implications for future REDD+ implementation. © 2015 The Authors

  3. The Role of Public-Private Partnerships in Local Infrastructure: the Case of Carbon Offset Projects

    International Nuclear Information System (INIS)

    Teichmann, Dorothee

    2011-01-01

    Investment in low carbon infrastructure is considered as an important component of the fight against climate change. The mechanisms of climate regulation (such as carbon offsets) transfer to project developers the risks associated with reducing emissions of greenhouse gas (GHG) emissions, i.e. operational and technological risk, or risks associated with the environmental monitoring and the regulatory mechanism itself. The success of projects - and thus their ability to attract private capital - depends importantly on the risk sharing arrangements between the private and public partners involved in the project. We show that the delegation of tasks between the partners can create risks that affect the environmental effectiveness and economic efficiency of the project. Contracts need to be well designed to mitigate those risks. For a sample of landfill gas flaring projects financed under the Clean Development Mechanism, it is shown that the out-sourcing of the provision of technology creates additional risks. The out-sourcing of the development of the Project Design Documents as required by UNFCCC and the separation of the operation of the landfill and the CDM project appear to be manageable by risk sharing arrangements between partners. In the latter case, each partner should bear the risk associated with his own responsibility. In fact, if carbon revenues are the only income stream for the CDM project developer, the incentive to reduce GHG emissions is maintained. (author)

    Full Text Available The Clean Development Mechanism (CDM of the Kyoto Protocol, allows the non Annex 1 countries to receive projects that contribute to reducing greenhouse gas emissions and sustainable development in developing countries. The CDM, since its inception, has issued credits equivalent to 1.434.737.562 tons of CO2, distributed across 7.450 projects around the world, from 15 different sectors. Sectors 14 that allow forestry projects (such as reforestation and afforestation have registered 53 projects to date; 19 of which are in Latin America. Nevertheless, the contribution of this sector currently represents less than 1% of CDM Certificates of Emissions Reduction (CERs issued. In September 2013, through their National Forestry Financing Fund (FONAFIFO, Costa Rica registered their first CDM project with the United Nations Framework Convention on Climate Change (UNFCCC, after having complied with all the project cycle processes. The project, known as "Carbon Sequestration in Small and Medium Farms, Brunca Region, Costa Rica" was a project executed by FONAFIFO under their Environmental Services Payment Program. This project was developed in Pérez Zeledón, San José, Costa Rica in partnership with the Cooperative Corporation CoopeAgri RL. The total goal of the project is to reduce the greenhouse gas emission by 176,050 ton of CO2-e, in a period of 20 years and commercialize the CERs in the regulated carbon market.

    Subsidies are extensively used for promoting the deployment of green technologies (renewables, clean development mechanism, electric vehicles...). Such policies may generate high windfall profits: some of the projects that benefited from the subsidies would have been undertaken anyway. The paper formalizes this situation using a simple principal agent framework under adverse selection. The agent may invest or not and obtain some private benefit in case of success. The principal observes both the investment and the eventual success, which generates a social benefit. Under some conditions it is shown that a subsidy paid conditional on failure (and not on success) limits the windfall profit while encouraging a large portfolio of projects to be invested. The relevance of this policy is discussed in the context of facilitating investment for infrastructure for fuel cell electric vehicles. (authors)

    A consortium of research partners led by the Southwest Regional Partnership on Carbon Sequestration and industry partners, including CAP CO2 LLC, Blue Source LLC, Coffeyville Resources, Nitrogen Fertilizers LLC, Ash Grove Cement Company, Kansas Ethanol LLC, Headwaters Clean Carbon Services, Black & Veatch, and Schlumberger Carbon Services, conducted a feasibility study of a large-scale CCS commercialization project that included large-scale CO{sub 2} sources. The overall objective of this project, entitled the 'Integrated Mid-Continent Carbon Capture, Sequestration and Enhanced Oil Recovery Project' was to design an integrated system of US mid-continent industrial CO{sub 2} sources with CO{sub 2} capture, and geologic sequestration in deep saline formations and in oil field reservoirs with concomitant EOR. Findings of this project suggest that deep saline sequestration in the mid-continent region is not feasible without major financial incentives, such as tax credits or otherwise, that do not exist at this time. However, results of the analysis suggest that enhanced oil recovery with carbon sequestration is indeed feasible and practical for specific types of geologic settings in the Midwestern U.S.

  9. Future Projections and Consequences of the Changing North American Carbon Cycle

    The rise of atmospheric carbon dioxide (CO2), primarily due to human-caused fossil fuel emissions and land-use change, has been dampened by carbon uptake by the oceans and terrestrial biosphere. Nevertheless, today's atmospheric CO2 levels are higher than at any time in the past 800,000 years. Over the past decade, there has been considerable effort to understand how carbon cycle changes interact with, and influence, atmospheric CO2 concentrations and thus climate. Here, we summarize the key findings related to projected changes to the North American carbon cycle and the consequences of these changes as reported in Chapters 17 and 19 of the 2nd State of the Carbon Cycle Report (SOCCR-2). In terrestrial ecosystems, increased atmospheric CO2 causes enhanced photosynthesis, plant growth, and water-use efficiency. Together, these may lead to changes in vegetation composition, carbon storage, hydrology and biogeochemical cycling. In the ocean, increased uptake of atmospheric CO2 causes ocean acidification, which leads to changes in reproduction, survival, and growth of many marine species. These direct physiological responses to acidification are likely to have indirect ecosystem-scale consequences that we are just beginning to understand. In all environments, the effects of rising CO2 also interact with other global changes. For example, nutrient availability can set limits on growth and a warming climate alters carbon uptake depending on a number of other factors. As a result, there is low confidence in the future evolution of the North American carbon cycle. For example, models project that terrestrial ecosystems could continue to be a net sink (of up to 1.19 PgC yr-1) or switch to a net source of carbon to the atmosphere (of up to 0.60 PgC yr-1) by the end of the century under business-as-usual emission scenarios. And, while North American coastal areas have historically been a sink of carbon (e.g., 2.6 to 3.5 PgC since 1995) and are projected to continue to take up

    Deforestation of temperate rainforests in Chile has decreased the provision of ecosystem services, including watershed protection, biodiversity conservation, and carbon sequestration. Forest conservation can restore those ecosystem services. Greenhouse gas policies that offer financing for the carbon emissions avoided by preventing deforestation require a projection of future baseline carbon emissions for an area if no forest conservation occurs. For a proposed 570 km{sup 2} conservation area in temperate rainforest around the rural community of Curinanco, Chile, we compared three methods to project future baseline carbon emissions: extrapolation from Landsat observations, Geomod, and Forest Restoration Carbon Analysis (FRCA). Analyses of forest inventory and Landsat remote sensing data show 1986-1999 net deforestation of 1900 ha in the analysis area, proceeding at a rate of 0.0003 y{sup -1}. The gross rate of loss of closed natural forest was 0.042 y{sup -1}. In the period 1986-1999, closed natural forest decreased from 20,000 ha to 11,000 ha, with timber companies clearing natural forest to establish plantations of non-native species. Analyses of previous field measurements of species-specific forest biomass, tree allometry, and the carbon content of vegetation show that the dominant native forest type, broadleaf evergreen (bosque siempreverde), contains 370 {+-} 170 t ha{sup -1} carbon, compared to the carbon density of non-native Pinus radiata plantations of 240 {+-} 60 t ha{sup -1}. The 1986-1999 conversion of closed broadleaf evergreen forest to open broadleaf evergreen forest, Pinus radiata plantations, shrublands, grasslands, urban areas, and bare ground decreased the carbon density from 370 {+-} 170 t ha{sup -1} carbon to an average of 100 t ha{sup -1} (maximum 160 t ha{sup -1}, minimum 50 t ha{sup -1}). Consequently, the conversion released 1.1 million t carbon. These analyses of forest inventory and Landsat remote sensing data provided the data to

    Climate change and the concurrent change in wildfire events and land use comprehensively affect carbon dynamics in both spatial and temporal dimensions. The purpose of this study was to project the spatial and temporal aspects of carbon storage in the Greater Yellowstone Ecosystem (GYE) under these changes from 2006 to 2050. We selected three emission scenarios and produced simulations with the CENTURY model using three General Circulation Models (GCMs) for each scenario. We also incorporated projected land use change and fire occurrence into the carbon accounting. The three GCMs showed increases in maximum and minimum temperature, but precipitation projections varied among GCMs. Total ecosystem carbon increased steadily from 7,942 gC/m 2 in 2006 to 10,234 gC/m 2 in 2050 with an annual rate increase of 53 gC/m 2 /year. About 56.6% and 27% of the increasing rate was attributed to total live carbon and total soil carbon, respectively. Net Primary Production (NPP) increased slightly from 260 gC/m 2 /year in 2006 to 310 gC/m 2 /year in 2050 with an annual rate increase of 1.22 gC/m 2 /year. Forest clear-cutting and fires resulted in direct carbon removal; however, the rate was low at 2.44 gC/m 2 /year during 2006-2050. The area of clear-cutting and wildfires in the GYE would account for 10.87% of total forested area during 2006-2050, but the predictive simulations demonstrated different spatial distributions in national forests and national parks. The GYE is a carbon sink during 2006-2050. The capability of vegetation is almost double that of soil in terms of sequestering extra carbon. Clear-cutting and wildfires in GYE will affect 10.87% of total forested area, but direct carbon removal from clear-cutting and fires is 109.6 gC/m 2 , which accounts for only 1.2% of the mean ecosystem carbon level of 9,056 gC/m 2 , and thus is not significant.

    Changing climate and land use practices have the potential to dramatically alter coupled hydrologic-biogeochemical processes and associated movement of water, carbon and nutrients through various terrestrial reservoirs into rivers, estuaries, and coastal ocean waters. Consequences of climate- and land use-related changes will be particularly evident in large river basins and their associated coastal outflow regions. Here, we describe a NASA Carbon Monitoring System project that employs an integrated suite of models in conjunction with remotely sensed as well as targeted in situ observations with the objectives of describing processes controlling fluxes on land and their coupling to riverine, estuarine and ocean ecosystems. The nature of our approach, coupling models of terrestrial and ocean ecosystem dynamics and associated carbon processes, allows for assessment of how societal and human-related land use, land use change and forestry and climate-related change affect terrestrial carbon transport as well as export of materials through watersheds to the coastal margins. Our objectives include the following: 1) Provide representation of carbon processes in the terrestrial ecosystem to understand how changes in land use and climatic conditions influence the export of materials to the coastal ocean, 2) Couple the terrestrial exports of carbon, nutrients and freshwater to a coastal biogeochemical model and examine how different climate and land use scenarios influence fluxes across the land-ocean interface, and 3) Project future changes under different scenarios of climate and human impact, and support user needs related to carbon management and other activities (e.g., water quality, hypoxia, ocean acidification). This research is providing information that will contribute to determining an overall carbon balance in North America as well as describing and predicting how human- and climate-related changes impact coastal water quality including possible effects of coastal

    This paper proposes a conceptual framework for evaluating the cost of projects to reduce atmospheric greenhouse gases (GHGs). The evaluation of cost-effectiveness should account for both the timing of carbon emissions and the damage caused by the atmospheric stock of carbon. We develop a conceptual basis to estimate the cost-effectiveness of projects in terms of the cost of reducing atmospheric carbon (CRAC) and other GHGs. CRAC accounts for the economic discount rate, alternative functional forms of the shadow price, the residence period of carbon in the atmosphere, and the multiple monetary benefits of projects. The last item is of particular importance to the developing countries

    2012-01-01

    Among the publications of CDC Climat Research, 'Climate Reports' offer in-depth analyses on a given subject. This issue addresses the following points: The agricultural sector accounts for 14% of global anthropogenic greenhouse gas emissions. If we also take into account carbon emissions and sequestration from upstream - production of fertilisers, deforestation, etc. - and downstream - bio-energies, etc. - the share rises to 30%. Many practices and technologies enable agriculture's impact on climate change to be reduced. According to a number of estimates that are summarised in this research, the agricultural sector's mitigation potential is of the same order of magnitude as its emissions over a period of 30 years. However, changing agricultural practices comes at a cost, and in most cases such changes are not made without economic incentives. Carbon offsetting projects are one of the economic tools available to reduce agricultural emissions by paying for metric tons of avoided CO 2 e emissions. A summary of the emission reductions enabled by agricultural projects to date is provided in this report. It covers most projects certified by quality assurance standards, including those set up by the Kyoto Protocol (Clean Development Mechanism and Joint Implementation) and those in the voluntary market (Verified Carbon Standard, Climate Action Reserve, Gold Standard, Chicago Climate Exchange, and American Carbon Registry). The assessment drawn up on this basis shows that emission reductions enabled through carbon offsetting are thousand times lower than actual emissions and their potential mitigation. Agricultural projects have reduced emissions by 14 MtCO 2 e in 2010, i.e. 7% of the reductions generated by all carbon offset projects across all sectors for this year. Initiatives focus on three technologies: - bio-energies (crop residues), - methanation of livestock waste, - and soil carbon sequestration using no-till practices. This is very little compared with the large

  20. Learning through a portfolio of carbon capture and storage demonstration projects

    2016-01-01

    Carbon dioxide capture and storage (CCS) technology is considered by many to be an essential route to meet climate mitigation targets in the power and industrial sectors. Deploying CCS technologies globally will first require a portfolio of large-scale demonstration projects. These first projects should assist learning by diversity, learning by replication, de-risking the technologies and developing viable business models. From 2005 to 2009, optimism about the pace of CCS rollout led to mutually independent efforts in the European Union, North America and Australia to assemble portfolios of projects. Since 2009, only a few of these many project proposals remain viable, but the initial rationales for demonstration have not been revisited in the face of changing circumstances. Here I argue that learning is now both more difficult and more important given the slow pace of deployment. Developing a more coordinated global portfolio will facilitate learning across projects and may determine whether CCS ever emerges from the demonstration phase.

  1. Personal disclosure revisited.

    Science.gov (United States)

    Olarte, Silvia W

    2003-01-01

    In this paper personal disclosure is defined as a conscious verbal presentation to the patient by the therapist of a personal vignette accompanied by the appropriate dynamic formulation and resolution of a given personal area of conflict. It is conceptualized within theoretical formulations which consider the therapeutic relationship a dyad, where the reality of the patient and the reality of the therapist influence each other, providing the matrix through which the resolution of the patient's past life experiences takes place in the context of this new interpersonal experience. It is specifically differentiated from a boundary violation, because the personal disclosure is brought to the patient's interactional awareness not for gratification of the therapist's sexual or narcissistic needs, but to provoke a response in the patient's conceptualization of a phenomenon being presented in the session and to actively influence the intersubjective field. Within the conceptual framework developed in this paper, personal disclosure reaffirms the patient's current self-discovery and provides for a different formative experience. Personal disclosure is not to be used by the therapist as a vehicle to resolve personal conflicts or as source of personal gratification. When used within the context developed in this paper, personal disclosure enhances both the patient's therapeutic process and the therapist's ever-evolving growth.

    Concern about global climate change is growing, and many projects and researchers are committed to reducing greenhouse gases from all possible sources. International Maritime (IMO) has set a target of 20% CO2 reduction from shipping by 2020 and also presented a series of carbon emission reduction methods, which are known as Energy Efficiency Design Index (EEDI) and Energy Efficiency Operation Indicator (EEOI). Reviews on carbon emission reduction from all industries indicate that, Carbon Capture and Storage (CCS) is an excellent solution to global warming. In this paper, a comprehensive literature review of EEDI and EEOI and CCS is conducted and involves reviewing current policies, introducing common technologies, and considering their feasibilities for marine activities, mainly shipping. Current projects are also presented in this paper, thereby illustrating that carbon emission reduction has been the subject of attention from all over the world. Two case ship studies indicate the economic feasibility of carbon emission reduction and provide a guide for CCS system application and practical installation on ships.

    2013-12-31

    The original overall objective of this activity was to undertake resource evaluation and planning for CCS projects and to describe and quantify the geologic, environmental, and economic challenges to successful development of large-scale CCS in China’s coal sector. Several project execution barriers were encountered in the course of this project, most notably a project stop/delay due to funds availability/costing restrictions from the US State Department to the US Department of Energy at the end of CY2012, which halted project execution from January 2, 2013 to April 1, 2013. At the resolution of this project delay, it was communicated to the project team that the overall project period would also be reduced, from a completion date of February 28, 2014 to December 31, 2013. The net impact of all these changes was a reduction in the project period from 24 months (3/1/2012-2/28/2014) to 22 months (3/1/2012-12/31/2013), with a 3 month stop from 1/1/2013-3/31/2013. The project team endeavored to overcome these project time impacts, focusing heavily on technoeconomic modeling that would be deliverable under Task 3 (Ordos Basin Feasibility Study), and choosing to abandon the full investigation into the Demonstration Site (Task 4) due to the reduced project time. The ultimate focus of this project changed to work with the Chinese on a carbon atlas/geologic characterization, and on mechanisms for CO2 storage options from high-quality streams within China.

    2018-04-01

    Mandatory green building regulations are often considered as the most effective tool to promote better energy efficiency and environmental protection. Nevertheless, its effectiveness compared to the voluntary counterpart has not been fully explored yet. In addressing this gap, this study aims to examine the environmental performance of green building stocks affected by the Australian mandatory building energy disclosure program. To this, this study analysed energy savings and carbon reduction efficiencies using the normalisation approach. The result shows that mandatory energy disclosure program did contribute to the reduction in energy usage and carbon emissions from the affected building stocks. More specifically, affected green building stocks showed a good efficiency especially in carbon reductions. The research results inform policymakers the possible improvement required for the mandatory disclosure program to increase the effectiveness towards dealing with the contemporary environmental issues aroused from the building sector, especially in energy savings perspective.

    2011-12-01

    Climate change can alter the role of plants and soils as sources or sinks of atmospheric carbon dioxide and result in changes in long-term carbon storage. To understand the sensitivity of Arizona's ecosystems to climate change, we quantified the present carbon stocks in Arizona's major ecosystem types using the NASA-CASA (Carnegie Ames Stanford Approach) model. Carbon stocks for each vegetation type included surface mineral soil, dead wood litter, standing wood and live leaf biomass. The total Arizona ecosystem carbon stock is presently 1775 MMtC, 545 MMtC of which is in Pinus ponderosa and Pinus edulis forests and woodlands. Evergreen forest vegetation, predominately Pinus ponderosa, has the largest current C density at 11.3 kgC/m2, while Pinus edulis woodlands have a C density of 6.0 kgC/m2. A change in climate will impact the suitable range for each tree species, and consequentially the amount of C stored. Present habitat ranges for these tree species are projected to have widespread mortality and likely will be replaced by herbaceous species, resulting in a loss of C stored. We evaluated the C storage implications over the 2010 to 2099 period of climate change based on output from GCMs with contrasting projections for the southwestern US: MPI-ECHAM5, which projects warming and reduced precipitation, and UKMO-HadGEM, which projects warming and increased precipitation. These projected changes are end points of a spectrum of possible future climate scenarios. The vegetation distribution models used describe potential suitable habitat, and we assumed that the growth rate for each vegetation type would be one-third of the way to full C density for each 30 year period up to 2099. With increasing temperature and decreasing precipitation predictions under the MPI-ECHAM5 model, P. ponderosa and P. edulis vegetation show a decrease in carbon stored from 545 MMtC presently to 116 MMtC. With the combined increase in temperature and precipitation, C storage in these

    With the goal of assessing the anthropogenic carbon-emission impact of urban centers on local and global climates, the Megacities Carbon Project has been building carbon-monitoring capabilities for the past two years around the Los Angeles metropolitan area. Hundreds of megabytes (MB) of data are generated daily, and distributed among data centers local to the sensor networks involved. We automatically pull this remotely generated data into a centralized data infrastructure local to the Jet Propulsion Laboratory (JPL), seeking to (1) provide collaboration opportunities on the data, and (2) generate refined data products through community-requested centralized data processing pipelines. The goal of this informatics effort is to ensure near real-time access to generated data products across the Los Angeles carbon monitoring sensor network and meet the data analysis needs of carbon researchers through the production of customized products. We discuss the goals of the informatics effort, its uniqueness, and assess its effectiveness in providing an insight into the carbon sphere of Los Angeles.

  11. Draft environmental impact statement: KENETECH/PacifiCorp Windpower Project, Carbon County, Wyoming

    International Nuclear Information System (INIS)

    1995-01-01

    This Draft Environmental Impact Statement assesses the environmental consequences of a proposed windpower development project in Carbon County, between Arlington and Hanna, Wyoming. Public scoping commenced in January 1994. All issues raised during scoping and interdisciplinary team preparation of the analysis are addressed. The proposed project entails the erection of approximately 1,390 wind turbine generators and associated facilities (e.g., roads, substations, distribution and communications lines) by KENETECH Windpower, Inc. A 230-kV transmission line would be built by PacifiCorp, Inc. to connect a proposed substation on Foote Creek Rim near Arlington to the Miner's substation near Hanna. The proposed project would use standard procedures as currently employed by other right-of-way projects, plus additional project-specific and site-specific mitigation measures to ensure that project impacts are minimized on all important resources. Impacts to most resources would be negligible to moderate during the life-of-project. Potentially significant impacts resulting from the project include avian mortality; declining avian populations; threatened, endangered, candidate, and/or state sensitive species mortality and/or habitat loss; disturbance to nearby residents due to noise; changes in visual resources; disturbance of important Native American traditional sites; changes in plant community species composition due to snow redistribution; displacement of big game due to windfarm operation; and loss of sage grouse nesting habitat. The proposed project could also have numerous beneficial impacts including increased revenues generated by taxes, increased employment, and benefits derived from using a nonpolluting resource for electric power generation

Potentially significant impacts from the project include avian mortality; declining avian populations; threatened, endangered, candidate, and/or state sensitive species mortality and/or habitat loss; disturbance to nearby residents due to noise; changes in visual resources; disturbance of important Native American traditional sites; changes in plant community species composition due to snow redistribution; displacement of big game due to windfarm operation; and loss of sage grouse nesting habitat. The proposed project could also have numerous beneficial impacts including increased revenues generated by taxes, increased employment, and benefits derived from using a nonpolluting resource for electric power generation

    Wetlands are important terrestrial ecosystems in Alaska. It is important to understand and assess their role in the regional carbon dynamics in response to historical and projected environmental conditions. A coupled modeling framework that incorporates a fire disturbance model and two biogeochemical models was used to assess the relative influence of changing climate, atmospheric carbon dioxide (CO2) concentration, and fire regime on the historical and future carbon balance in wetland ecosystems of the four main Landscape Conservation Cooperatives (LCCs) of Alaska. Simulations were conducted for the historical period (1950-2009) and future projection period (2010-2099). These simulations estimate that the total carbon (C) storage in wetland ecosystems of Alaska is 5556 Tg C in 2009, with 89% of the C stored in soils. An estimated 175 Tg C was lost during the historical period, which is attributed to greater C lost from the Northwest Boreal LCC than C gained from the other three LCCs. The simulations for the projection period were conducted for six different scenarios driven by climate forcings from two different climate models for each of three CO2 emission scenarios. The mean total carbon storage increased 3.94 Tg C/yr by 2099, with variability among the simulations ranging from 2.02 Tg C/yr to 4.42 Tg C/yr. Across the four LCCs, the largest relative C storage increase occurred in the Arctic and North Pacific LCCs. These increases were primarily driven by increases in net primary production (NPP) that were greater than increases in heterotrophic respiration and fire emissions. Our analysis further indicates that NPP increase was primarily driven by CO2 fertilization ( 5% per 100 ppmv increase) as well as by increases in air temperature ( 1% per ° increase). Increases air temperature were estimated to be the primary cause for a projected 47.7% mean increase in wetlands biogenic CH4 emissions among the simulations ( 15% per ° increase). The combined effects of

    Carbon dioxide capture and storage (CCS) provides options for making continued use of fossil fuels more compatible with pollution abatement policies. This paper evaluated policy issues related to CCS, with particular focus on the geological sequestration of carbon dioxide (CO 2 ) into geological storage sites. Before any carbon dioxide (CO 2 ) CCS activities can be included in the portfolio of climate change mitigation activities, several issues need to be resolved such as the development of appropriate accounting and baselines rules and monitoring modalities. Guidance and policies on baselines and the accounting of emission reductions are critical to ensure that CCS projects can benefit from CO 2 markets and are recognized under various mitigation schemes. This paper examined the major issues that should considered along with changes to current accounting approaches. Issues that need to be addressed in order to prepare national inventories for the inclusion of CCS under the United Nations Framework Convention on Climate Change (UNFCCC) and emission reduction schemes such as the European greenhouse gas emissions trading scheme were first presented, followed by an examination of CCS issues under project-based mechanisms such as the Kyoto Protocol's Clean Development Mechanism. The importance of clear definitions and monitoring guidelines for the proper accounting of CCS were also highlighted. 12 refs., 2 figs

    Full Text Available The aim in this study is to identify the tax treatment applied to carbon credit operations in Brazilian companies that are developing projects in the context of the Clean Development Mechanism (CDM. Therefore, an exploratory research with a qualitative approach was developed. Data were collected with the help of questionnaire, forwarded to all Brazilian companies with CDM projects that received approval from the Inter-Ministerial Commission on Global Climate Change (CIMGC without safeguards, according to the list of the Brazilian Ministry of Science and Technology. Out of 117 companies listed, only five answered the research instrument, which represents an accessibility sample. The results show that, as for the tax treatment applied in the companies under analysis, IRPJ and CSLL should be charged on carbon credit operations. Regarding PIS, COFINS, ISS, some companies considered that these taxes are due and others that they are not. There is a consensus, though, about the fact that ICMS and IOF should not be charged. In conclusion, no uniform understanding exists as of yet about due taxes in the research sample, as no specific fiscal legislation exists yet on carbon credits in Brazil.

    We report continuous surface observations of carbon dioxide (CO2) and methane (CH4) from the Los Angeles (LA) Megacity Carbon Project during 2015. We devised a calibration strategy, methods for selection of background air masses, calculation of urban enhancements, and a detailed algorithm for estimating uncertainties in urban-scale CO2 and CH4 measurements. These methods are essential for understanding carbon fluxes from the LA megacity and other complex urban environments globally. We estimate background mole fractions entering LA using observations from four extra-urban sites including two marine sites located south of LA in La Jolla (LJO) and offshore on San Clemente Island (SCI), one continental site located in Victorville (VIC), in the high desert northeast of LA, and one continental/mid-troposphere site located on Mount Wilson (MWO) in the San Gabriel Mountains. We find that a local marine background can be established to within ˜ 1 ppm CO2 and ˜ 10 ppb CH4 using these local measurement sites. Overall, atmospheric carbon dioxide and methane levels are highly variable across Los Angeles. Urban and suburban sites show moderate to large CO2 and CH4 enhancements relative to a marine background estimate. The USC (University of Southern California) site near downtown LA exhibits median hourly enhancements of ˜ 20 ppm CO2 and ˜ 150 ppb CH4 during 2015 as well as ˜ 15 ppm CO2 and ˜ 80 ppb CH4 during mid-afternoon hours (12:00-16:00 LT, local time), which is the typical period of focus for flux inversions. The estimated measurement uncertainty is typically better than 0.1 ppm CO2 and 1 ppb CH4 based on the repeated standard gas measurements from the LA sites during the last 2 years, similar to Andrews et al. (2014). The largest component of the measurement uncertainty is due to the single-point calibration method; however, the uncertainty in the background mole fraction is much larger than the measurement uncertainty. The background uncertainty for the marine

    highly corrosive nature of the typical amine-based separation process leads to high plant capital investment. According to recent DOE-NETL studies, MEA-based CCS will increase the cost of electricity of a new pulverized coal plant by 80-85% and reduce the net plant efficiency by about 30%. Non-power industrial facilities will incur similar production output and efficiency penalties when implementing conventional carbon capture systems. The proposed large scale demonstration project combining advanced amine CO{sub 2} capture integrated with commercial EOR operations significantly advances post-combustion technology development toward the DOE objectives of reducing the cost of energy production and improving the efficiency of CO{sub 2} Capture technologies. WPC has assembled a strong multidisciplinary team to meet the objectives of this project. WPC will provide the host site and Hitachi will provide the carbon capture technology and advanced solvent. Burns and Roe bring expertise in overall engineering integration and plant design to the team. Core Energy, an active EOR producer/operator in the State of Michigan, is committed to support the detailed design, construction and operation of the CO{sub 2} pipeline and storage component of the project. This team has developed a Front End Engineering Design and Cost Estimate as part of Phase 1 of DOE Award DE-FE0002477.

    The financial implications of implementing a new forest management paradigm have not been well understood and have often been underestimated. Resource needs for e.g., stakeholder consultation, capacity building and addressing the political economy are seldom fully accounted for in the resource needs estimates put forward in connection to REDD+. This report investigates the economics of implementing forest and REDD+ projects through eight case studies from Africa, Latin America and Asia, analyzing real forest and REDD+ investments. The report is part of efforts to share financial experiences and lessons learned with policymakers, project developers and stakeholders, with the objective to inform forest project and strategy development. It presents experiences and advice on the risks, costs and revenues of forest projects, thereby informing not only the development of future REDD+ initiatives but also the testing of advanced market commitments as a finance option for sustainable forest management. The findings in the report underline the fact that only through sound and transparent financial information will forest projects and national forest initiatives become interesting for private financial institutions and comparable with other investment opportunities. It is therefore important to include robust analysis of the operations business case and its financial attractiveness to commercial investors, early in the design process. As for the economics of forest and forest carbon projects, it appears that REDD+ payments alone, especially at current prices, will not deliver the revenues that cover all expenses of transparent and long-term mitigation of forest carbon emissions. Instead the findings underline the importance of building up forest operations which effectively manages risk and delivers several revenue streams. These findings are aligned with the advocacy efforts of UNEP and the UN-REDD Programme on multiple benefits and the combination of various funding and

In particular, this paper reviews the complexities involved for customers, suppliers and business partners to communicate about Y2K issues. The review prominently features the many levels of statutory, regulatory and legal overlay that must be considered before any communication takes place . One of the major barriers to disclosure is the threat that any statements made by one company or individual to another may give rise to various forms of liability, including limitation, defamation, misrepresentation, detrimental reliance, collateral contracts and warranties or representations. The paper also describes recent Canadian and U.S. Y2K disclosure requirements for public companies. While the legislation is intended to promote the voluntary sharing of Y2K information, it also sets out conditions limiting the extent to which Y2K statements can be used as the basis for liability. Canadian regulatory bodies also have several policies in effect that compel issuers of new securities to emphasize uncertainties which are likely to be factors in Y2K, and public companies to discuss and analyze risks, events and uncertainties within the management discussion and analysis section of their annual reports that would cause reported financial information to be not necessarily indicative of future operating results or conditions, should those uncertainties materialize. 8 refs.

    Commercial off-the-shelf lidar collections associated with tree measures in field plots allow aboveground biomass (AGB) estimation with high confidence. Predictive models developed from such datasets are used operationally to map AGB across lidar project areas. We use a random selection of these pixel-level AGB predictions as training for predicting AGB annually across Idaho and western Montana, primarily from Landsat time series imagery processed through LandTrendr. At both the landscape and regional scales, Random Forests is used for predictive AGB modeling. To project future carbon dynamics, we use Climate-FVS (Forest Vegetation Simulator), the tree growth engine used by foresters to inform forest planning decisions, under either constant or changing climate scenarios. Disturbance data compiled from LandTrendr (Kennedy et al. 2010) using TimeSync (Cohen et al. 2010) in forested lands of Idaho (n=509) and western Montana (n=288) are used to generate probabilities of disturbance (harvest, fire, or insect) by land ownership class (public, private) as well as the magnitude of disturbance. Our verification approach is to aggregate the regional, annual AGB predictions at the county level and compare them to annual county-level AGB summarized independently from systematic, field-based, annual inventories conducted by the US Forest Inventory and Analysis (FIA) Program nationally. This analysis shows that when federal lands are disturbed the magnitude is generally high and when other lands are disturbed the magnitudes are more moderate. The probability of disturbance in corporate lands is higher than in other lands but the magnitudes are generally lower. This is consistent with the much higher prevalence of fire and insects occurring on federal lands, and greater harvest activity on private lands. We found large forest carbon losses in drier southern Idaho, only partially offset by carbon gains in wetter northern Idaho, due to anticipated climate change. Public and

    In U.S. Atlantic coastal areas, hurricanes are a principal agent of catastrophic wind damage, with dramatic impacts on the structure and functioning of forests. Substantial recent progress has been made to estimate the biomass loss and resulting carbon emissions caused by hurricanes impacting the U.S. Additionally, efforts to evaluate the net effects of hurricanes on the regional carbon balance have demonstrated the importance of viewing large disturbance events in the broader context of recovery from a mosaic of past events. Viewed over sufficiently long time scales and large spatial scales, regrowth from previous storms may largely offset new emissions; however, changes in number, strength or spatial distribution of extreme disturbance events will result in changes to the equilibrium state of the ecosystem and have the potential to result in a lasting carbon source or sink. Many recent studies have linked climate change to changes in the frequency and intensity of hurricanes. In this study, we use a mechanistic ecosystem model, the Ecosystem Demography (ED) model, driven by scenarios of future hurricane activity based on historic activity and future climate projections, to evaluate how changes in hurricane frequency, intensity and spatial distribution could affect regional carbon storage and flux over the coming century. We find a non-linear response where increased storm activity reduces standing biomass stocks reducing the impacts of future events. This effect is highly dependent on the spatial pattern and repeat interval of future hurricane activity. Developing this kind of predictive modeling capability that tracks disturbance events and recovery is key to our understanding and ability to predict the carbon balance of forests.

    We evaluated three spatially explicit land use and cover change (LUCC) models to project deforestation from 2005-2020 in the carbon-rich peat swamp forests (PSF) of Central Kalimantan, Indonesia. Such models are increasingly used to evaluate the impact of deforestation on carbon fluxes between the biosphere and the atmosphere. We considered both business-as-usual (BAU) and a forest protection scenario to evaluate each model's accuracy, sensitivity, and total projected deforestation and landscape-level fragmentation patterns. The three models, Dinamica EGO (DE), GEOMOD and the Land Change Modeler (LCM), projected similar total deforestation amounts by 2020 with a mean of 1.01 million ha (Mha) and standard deviation of 0.17 Mha. The inclusion of a 0.54 Mha strict protected area in the LCM simulations reduced projected loss to 0.77 Mha over 15 years. Calibrated parameterizations of the models using nearly identical input drivers produced very different landscape properties, as measured by the number of forest patches, mean patch area, contagion, and Euclidean nearest neighbor determined using Fragstats software. The average BAU outputs of the models suggests that Central Kalimantan may lose slightly less than half (45.1%) of its 2005 PSF by 2020 if measures are not taken to reduce deforestation there. The relatively small reduction of 0.24 Mha in deforestation found in the 0.54 Mha protection scenario suggests that these models can identify potential leakage effects in which deforestation is forced to occur elsewhere in response to a policy intervention.

    We summarize the results of a recent interagency assessment of land carbon dynamics in Alaska, in which carbon dynamics were estimated for all major terrestrial and aquatic ecosystems for the historical period (1950-2009) and a projection period (2010-2099). Between 1950 and 2009, upland and wetland (i.e., terrestrial) ecosystems of the State gained 0.4 Tg C yr -1 (0.1% of net primary production, NPP), resulting in a cumulative greenhouse gas radiative forcing of 1.68 x 10 -3 W m -2 . The change in carbon storage is spatially variable with the region of the Northwest Boreal Landscape Conservation Cooperative (LCC) losing carbon because of fire disturbance. The combined carbon transport via various pathways through inland aquatic ecosystems of Alaska was estimated to be 41.3 Tg C yr -1 (17% of terrestrial NPP). During the projection period (2010-2099), carbon storage of terrestrial ecosystems of Alaska was projected to increase (22.5 to 70.0 Tg C yr -1 ), primarily because of NPP increases of 10 to 30% associated with responses to rising atmospheric CO 2 , increased nitrogen cycling, and longer growing seasons. Although carbon emissions to the atmosphere from wildfire and wetland CH 4 were projected to increase for all of the climate projections, the increases in NPP more than compensated for those losses at the statewide level. Carbon dynamics of terrestrial ecosystems continue to warm the climate for four of the six future projections, and cool the climate for only one of the projections. The attribution analyses we conducted indicated that the response of NPP in terrestrial ecosystems to rising atmospheric CO 2 (~5% per 100 ppmv CO 2 ) saturates as CO 2 increases (between approximately +150 and +450 ppmv among projections). This response, along with the expectation that permafrost thaw would be much greater and release large quantities of permafrost carbon after 2100, suggests that projected carbon gains in terrestrial ecosystems of Alaska may not be sustained

The manager can signal project quality to investors by making a (possibly costly) forward-looking disclosure about her project's potential for success. We find that if the manager's disclosures are costly, she will never release forward-looking statements that do not convey information to external investors. Furthermore, managers of f...

    Chinese stakeholders (131) from 68 key institutions in 27 provinces were consulted in spring 2009 in an online survey of their perceptions of the barriers and opportunities in financing large-scale carbon dioxide capture and storage (CCS) demonstration projects in China. The online survey was supplemented by 31 follow-up face-to-face interviews. The National Development and Reform Commission (NDRC) was widely perceived as the most important institution in authorizing the first commercial-scale CCS demonstration project and authorization was viewed as more similar to that for a power project than a chemicals project. There were disagreements, however, on the appropriate size for a demonstration plant, the type of capture, and the type of storage. Most stakeholders believed that the international image of the Chinese Government could benefit from demonstrating commercial CCS and that such a project could also create advantages for Chinese companies investing in CCS technologies. In more detailed interviews with 16 financial officials, we found striking disagreements over the perceived risks of demonstrating CCS. The rate of return seen as appropriate for financing demonstration projects was split between stakeholders from development banks (who supported a rate of 5-8%) and those from commercial banks (12-20%). The divergence on rate alone could result in as much as a 40% difference in the cost of CO(2) abatement and 56% higher levelized cost of electricity based on a hypothetical case study of a typical 600-MW new build ultrasupercritical pulverized coal-fired (USCPC) power plant. To finance the extra operational costs, there were sharp divisions over which institutions should bear the brunt of financing although, overall, more than half of the support was expected to come from foreign and Chinese governments.

    No mandatory national program currently exists to mitigate climate change in the US Consequently, voluntary programs and mandatory state-level programs are multiplying to allow users to register emission-offset activities, creating multiple often contradictory measurement and recording standards. For the land use sector we examined a hypothetical project: tree planting on rangelands in California. We apply four sets of protocols from the following registries - the California Climate Action Registry, the Chicago Climate Exchange (CCX), the Regional Greenhouse Gas Initiative and the USDOE 1605(b) program - and compare the results to the 'actual' net sequestration and also briefly compare them to international protocols such as the relevant Clean Development Mechanism methodology. Carbon in land use can be estimated accurately, precisely and cost-effectively, but to achieve this requires good protocols. As predicted, the consequence of applying different protocols for reportable carbon was significant. The choice of measurement pools, the handling of the baseline and the issue of uncertainty led to a baseline estimate of 0-66,690 t CO 2 -e, and final sequestered carbon totals (after 60 years) that varied between 118,044 and 312,685 t CO 2 -e-a factor of 2.5 difference. The amount reported under 1605(b) is the closest to 'actual' with CCX entity reporting the most divergent

    The SMAP (Soil Moisture Active Passive) Level-4 projects aims to develop a fully coupled hydrology-vegetation data assimilation algorithm to generate improved estimates of modeled hydrological fields and carbon fluxes. This includes using the new NASA Catchment-CN (Catchment-Carbon-Nitrogen) model, which combines the Catchment land surface hydrology model with dynamic vegetation components from the Community Land Model version 4 (CLM4). As such, Catchment-CN allows a more realistic, fully coupled feedback between the land hydrology and the biosphere. The L4 ECO project further aims to inform the model through the assimilation of Soil Moisture Active Passive (SMAP) brightness temperature observations as well as observations of Moderate Resolution Imaging Spectroradiometer (MODIS) fraction of absorbed photosynthetically active radiation (FPAR). Preliminary results show that the assimilation of SMAP observations leads to consistent improvements in the model soil moisture skill. An evaluation of the Catchment-CN modeled vegetation characteristics showed that a calibration of the model's vegetation parameters is required before an assimilation of MODIS FPAR observations is feasible.

    The disclosure requirements imposed on Canadian public companies are discussed. The basis of the capital market system in Canada is the integrity of full and true disclosure of all material facts in a prospectus and continuous disclosure of material changes and information, including financial results. Securities regulators have the right to report to the appropriate law enforcement agencies any company director who intentionally files misleading financial statements or press releases. The fundamental policy of Canadian stock exchanges is that all persons investing in securities listed on an exchange have equal access to information that may affect their investment decisions. Canadian stock exchanges have developed by-laws, rules and regulations relating to listed companies disclosure obligations, breach of which may lead to suspension of trading, delisting of the securities of the offending issuer, and substantial fines. Details of civil and criminal liability, current and proposed, for incomplete or inaccurate disclosure under Canadian securities legislation are explained. 59 refs

    This report summarizes the Phase I research and development work performed during the March 13, 2015 to July 13, 2016 period. The proposal for this work was submitted in response to NASA Research Announcement NNH14ZOA001N, "Space Technology Research, Development, Demonstration, and Infusion 2014 (SpaceTech-REDDI-2014)," Appendix 14GCD-C2 "Game Changing Development Program, Advanced Oxygen Recovery for Spacecraft Life Support Systems Appendix" The Task Agreement for this Phase I work is Document Control Number: GCDP-02-TA-15015. The objective of the Phase I project was to demonstrate in laboratories two Engineering Development Units (EDU) that perform critical functions of the low temperature carbon dioxide electrolysis and the catalytic conversion of carbon monoxide into carbon and carbon dioxide. The low temperature carbon dioxide electrolysis EDU was built by the University of Delaware with Dr. Feng Jiao as the principal investigator in charge of this EDU development (under NASA Contract NNC15CA04C). The carbon monoxide catalytic conversion EDU was built by the NASA Glenn Research Center with Kenneth Burke as the principal investigator and overall project leader for the development of both EDUs. Both EDUs were successfully developed and demonstrated the critical functions for each process. The carbon dioxide electrolysis EDU was delivered to the NASA Johnson Space Center and the carbon monoxide catalytic conversion EDU was delivered to the NASA Marshall Spaceflight Center.

    Conversion of cropland into perennial vegetation land can increase soil organic carbon (SOC) accumulation, which might be an important mitigation measure to sequester carbon dioxide from the atmosphere. The “Grain for Green” project, one of the most ambitious ecological programmes launched in modern China, aims at transforming the low-yield slope cropland into grassland and woodland. The Loess Plateau in China is the most important target of this project due to its serious soil erosion. The objectives of this study are to answer three questions: (1) what is the rate of the SOC accumulation for this “Grain for Green” project in Loess Plateau? (2) Is there a difference in SOC sequestration among different restoration types, including grassland, shrub and forest? (3) Is the effect of restoration types on SOC accumulation different among northern, middle and southern regions of the Loess Plateau? Based on analysis of the data collected from the literature conducted in the Loess Plateau, we found that SOC increased at a rate of 0.712 TgC/year in the top 20 cm soil layer for 60 years under this project across the entire Loess Plateau. This was a relatively reliable estimation based on current data, although there were some uncertainties. Compared to grassland, forest had a significantly greater effect on SOC accumulation in middle and southern Loess Plateau but had a weaker effect in the northern Loess Plateau. There were no differences found in SOC sequestration between shrub and grassland across the entire Loess Plateau. Grassland had a stronger effect on SOC sequestration in the northern Loess Plateau than in the middle and southern regions. In contrast, forest could increase more SOC in the middle and southern Loess Plateau than in the northern Loess Plateau, whereas shrub had a similar effect on SOC sequestration across the Loess Plateau. Our results suggest that the “Grain for Green” project can significantly increase the SOC storage in Loess Plateau

    The paper examined the case study of the Saudi electricity sector and provided projections for energy use and respective carbon dioxide (CO 2 ) emissions for the period 2010–2025 with and without cleaner energy technologies. Based on two sets of 20 life cycle assessment studies for carbon capture and storage and solar photovoltaic technologies, CO 2 emission reduction rates were used for projecting future CO 2 emissions. Results showed enormous savings in CO 2 emissions, for the most likely case, year 2025 reported savings that range from 136 up to 235 MtCO 2 . Including low growth and high growth cases, these savings could range from 115 up to 468 MtCO 2 presenting such an unrivalled opportunity for Saudi Arabia. These projections were developed as a way of translating the inherent advantages that cleaner energy technologies could provide for CO 2 emissions savings. It is hoped that the results of this paper would inform energy policymaking in Saudi Arabia. - Highlights: • Electricity use in Saudi Arabia is predicted in the period 2010–2025. • Use of photovoltaic plants and carbon capture and storage are considered. • Life cycle assessment of the options is conducted. • Carbon emissions with and without the renewable energy are estimated. • The projections showcase the CO 2 emissions savings

    There are concerns that Reduced Emissions from Deforestation and forest Degradation (REDD+) may fail to deliver potential biodiversity cobenefits if it is focused on high carbon areas. We explored the spatial overlaps between carbon stocks, biodiversity, projected deforestation threats, and the location of REDD+ projects in Indonesia, a tropical country at the forefront of REDD+ development. For biodiversity, we assembled data on the distribution of terrestrial vertebrates (ranges of amphibians, mammals, birds, reptiles) and plants (species distribution models for 8 families). We then investigated congruence between different measures of biodiversity richness and carbon stocks at the national and subnational scales. Finally, we mapped active REDD+ projects and investigated the carbon density and potential biodiversity richness and modeled deforestation pressures within these forests relative to protected areas and unprotected forests. There was little internal overlap among the different hotspots (richest 10% of cells) of species richness. There was also no consistent spatial congruence between carbon stocks and the biodiversity measures: a weak negative correlation at the national scale masked highly variable and nonlinear relationships island by island. Current REDD+ projects were preferentially located in areas with higher total species richness and threatened species richness but lower carbon densities than protected areas and unprotected forests. Although a quarter of the total area of these REDD+ projects is under relatively high deforestation pressure, the majority of the REDD+ area is not. In Indonesia at least, first-generation REDD+ projects are located where they are likely to deliver biodiversity benefits. However, if REDD+ is to deliver additional gains for climate and biodiversity, projects will need to focus on forests with the highest threat to deforestation, which will have cost implications for future REDD+ implementation.

    Public financial institutions (PFIs) are well-positioned to act as a key leverage point for governments' efforts to mobilise private investment in low-carbon projects and infrastructure. The study identifies the tools, instruments and approaches used by five PFIs to directly support and scale-up domestic private sector investment in sustainable transport, energy-efficiency and renewable energy in OECD countries. Between 2010-2012, these five institutions - Group Caisse des Depots in France, KfW Bankengruppe in Germany, the UK Green Investment Bank, the European Investment Bank, and the European Bank for Reconstruction and Development - have provided over 100 billion euros of equity investment and financing for energy efficiency, renewable energy and sustainable transport projects. They use both traditional and innovative approaches to link low-carbon projects with finance through enhancing access to capital; facilitating risk reduction and sharing; improving the capacity of market actors; and shaping broader market practices and conditions.

    1990-07-01

    The existing switchyards at Western Area Power Administration's (WESTERN) Seminoe and Kortes facilities, located approximately 40 miles northeast of Rawlines, Carbon County, Wyoming, were constructed in 1939 and 1951, respectively. The circuit breakers at these facilities are beyond or approaching their service life and need to be replaced. In addition, the switchyards have poor access for maintenance and replacement of equipment, and their locations create potential for oil spills into the North Platte River. WESTERN is proposing to consolidate the switchyard facilities into one new substation to provide easier access, restore proper levels of system reliability, and decrease the potential for oil contamination of the river. This environmental assessment (EA) was prepared to evaluate the impacts of the proposed Seminoe-Kortes Consolidation Project. 57 refs., 12 figs., 8 tabs.

    2014-05-01

    TESS (Towards European Societal Sustainability -- www.tess-transition.eu) is a three-year, European-wide research project. It aims to reach an understanding of the potential for community-led initiatives to help deliver a truly sustainable, low-carbon future. Transitions to low-carbon societies take place at multiple and complementary scales. Transition processes are highly dependent on the innovative potential of community-based initiatives and their articulation with appropriate institutional architecture. Community-based initiatives are potentially more adaptable and less constrained by current structural circumstances than top-down policies and can give impetus to large-scale and technology driven changes. TESS will provide an understanding on the upscaling possibilities of such high-potential community-based initiatives by addressing two main questions: What is the impact of community-based initiatives in terms of carbon reduction potential and economic effect? What institutional structures (values, policies and mechanisms) support these initiatives in persisting beyond the initial phase and moving into an acceleration phase, spreading desired impacts? Answers will be provided through (1) a novel measuring, reporting and verification (MRV) framework for benchmarking community-based initiatives. This will enable quantifiable, comparable and standardised evaluation, and (2) the identification of success factors for the emergence, persistence and diffusion of promising initiatives, including online initiatives. We will identify these initiatives through case studies across regions and sectors and produce a systemic understanding of their impact on societal transitions towards sustainability. Our research will be integrated and transdisciplinary, with the unique opportunity to bring together social and natural scientists to foster a transition towards European societal sustainability. Our work will feed into and extend the Climate Adapt database to facilitate

    The report is intended to be a guidance document for project developers, investors, lenders, and CDM host countries involved in wind power projects in the CDM. The report explores in particular those issues that are important in CDM project assessment and development - that is, baseline development, carbon financing, and environmental sustainability. It does not deal in detail with those issues that are routinely covered in a standard wind power project assessment. The report tests, compares, and recommends methodologies for and approaches to baseline development. To present the application and implications of the various methodologies and approaches in a concrete context, Africa's largest wind farm-namely the 60 MW wind farm located in Zafarana, Egypt- is examined as a hypothetical CDM wind power project The report shows that for the present case example there is a difference of about 25% between the lowest (0.5496 tCO2/MWh) and the highest emission rate (0.6868 tCO 2 /MWh) estimated in accordance with these three standardized approaches to baseline development according to the Marrakesh Accord. This difference in emission factors comes about partly as a result of including hydroelectric power in the baseline scenario. Hydroelectric resources constitute around 21% of the generation capacity in Egypt, and, if excluding hydropower, the difference between the lowest and the highest baseline is reduced to 18%. Furthermore, since the two variations of the 'historical' baseline option examined result in the highest and the lowest baselines, by disregarding this baseline option altogether the difference between the lowest and the highest is reduced to 16%. The ES3-model, which the Systems Analysis Department at Risoe National Laboratory has developed, makes it possible for this report to explore the project-specific approach to baseline development in some detail. Based on quite disaggregated data on the Egyptian electricity system, including the wind power production

  11. Integrating invasive grasses into carbon cycle projections: Cogongrass spread in southern pine forests

    Forested ecosystems are currently being disrupted by invasive species. One example is the invasive grass Imperata cylindrica (cogongrass), which is widespread in southeastern US pine forests. Pines forests dominate the forest cover of the southeast, and contribute to making the Southeast the United States' largest carbon sink. Cogongrass decreases the colonization of loblolly pine fine roots. If cogongrass continues to invade,this sink could be jeopardized. However, the effects of cogongrass invasion on carbon sequestration are largely unknown. We have projected the effects of elevated CO2 and changing climate on future cogongrass invasion. To test how pine stands are affected by cogongrass, cogongrass invasions were modeled using the Ecosystem Demography 2 (ED2) model, and parameterized using the Predictive Ecosystem Analyzer (PEcAn). ED2 takes into account local meteorological data, stand populations and succession, disturbance, and geochemical pools. PEcAn is a workflow that uses Bayesian sensitivity analyses and variance decomposition to quantify the uncertainty that each parameter contributes to overall model uncertainty. ED2 was run for four NEON and Ameriflux sites in the Southeast from the earliest available census of the site into 2010. These model results were compared to site measures to test for model accuracy and bias. To project the effect of elevated CO2 on cogongrass invasions, ED was run from 2006-2100 at four sites under four separate scenarios: 1) RPC4.5 CO2 and climate, 2) RPC4.5 climate only, with constant CO2 concentrations, 3) RPC4.5 Elevated CO2 only, with climate randomly selected from 2006-2026, 4) Present Day, made from randomly selected measures of CO2 and radiation from 2006-2026. Each scenario was run three times; once with cogongrass absent, once with a low cogongrass abundance, and once with a high cogongrass abundance. Model results suggest that many relevant parameters have high uncertainty due to lack of measurement. Further field

    National guidelines call for health care organizations to provide around-the-clock coaching for medical error disclosure. However, frontline clinicians may not always seek risk managers for coaching. As part of a demonstration project designed to improve patient safety and reduce malpractice liability, we trained multidisciplinary disclosure coaches at 8 health care organizations in Washington State. The training was highly rated by participants, although not all emerged confident in their coaching skill. This multisite intervention can serve as a model for other organizations looking to enhance existing disclosure capabilities. Success likely requires cultural change and repeated practice opportunities for coaches. © 2017 American Society for Healthcare Risk Management of the American Hospital Association.

    The role of carbon (C) and nitrogen (N) interactions on sequestration of atmospheric CO2 in black spruce ecosystems across North America was evaluated with the Terrestrial Ecosystem Model (TEM) by applying parameterizations of the model in which C-N dynamics were either coupled or uncoupled. First, the performance of the parameterizations, which were developed for the dynamics of black spruce ecosystems at the Bonanza Creek Long-Term Ecological Research site in Alaska, were evaluated by simulating C dynamics at eddy correlation tower sites in the Boreal Ecosystem Atmosphere Study (BOREAS) for black spruce ecosystems in the northern study area (northern site) and the southern study area (southern site) with local climate data. We compared simulated monthly growing season (May to September) estimates of gross primary production (GPP), total ecosystem respiration (RESP), and net ecosystem production (NEP) from 1994 to 1997 to available field-based estimates at both sites. At the northern site, monthly growing season estimates of GPP and RESP for the coupled and uncoupled simulations were highly correlated with the field-based estimates (coupled: R2= 0.77, 0.88 for GPP and RESP; uncoupled: R2 = 0.67, 0.92 for GPP and RESP). Although the simulated seasonal pattern of NEP generally matched the field-based data, the correlations between field-based and simulated monthly growing season NEP were lower (R2 = 0.40, 0.00 for coupled and uncoupled simulations, respectively) in comparison to the correlations between field-based and simulated GPP and RESP. The annual NEP simulated by the coupled parameterization fell within the uncertainty of field-based estimates in two of three years. On the other hand, annual NEP simulated by the uncoupled parameterization only fell within the field-based uncertainty in one of three years. At the southern site, simulated NEP generally matched field-based NEP estimates, and the correlation between monthly growing season field-based and

  15. Observationally-based Metrics of Ocean Carbon and Biogeochemical Variables are Essential for Evaluating Earth System Model Projections

    2017-12-01

    The Southern Ocean is central to the climate's response to increasing levels of atmospheric greenhouse gases as it ventilates a large fraction of the global ocean volume. Global coupled climate models and earth system models, however, vary widely in their simulations of the Southern Ocean and its role in, and response to, the ongoing anthropogenic forcing. Due to its complex water-mass structure and dynamics, Southern Ocean carbon and heat uptake depend on a combination of winds, eddies, mixing, buoyancy fluxes and topography. Understanding how the ocean carries heat and carbon into its interior and how the observed wind changes are affecting this uptake is essential to accurately projecting transient climate sensitivity. Observationally-based metrics are critical for discerning processes and mechanisms, and for validating and comparing climate models. As the community shifts toward Earth system models with explicit carbon simulations, more direct observations of important biogeochemical parameters, like those obtained from the biogeochemically-sensored floats that are part of the Southern Ocean Carbon and Climate Observations and Modeling project, are essential. One goal of future observing systems should be to create observationally-based benchmarks that will lead to reducing uncertainties in climate projections, and especially uncertainties related to oceanic heat and carbon uptake.

  20. The Impact of Variable Phytoplankton Stoichiometry on Projections of Primary Production, Food Quality, and Carbon Uptake in the Global Ocean

    Science.gov (United States)

    2018-04-01

    Ocean biogeochemical models are integral components of Earth system models used to project the evolution of the ocean carbon sink, as well as potential changes in the physical and chemical environment of marine ecosystems. In such models the stoichiometry of phytoplankton C:N:P is typically fixed at the Redfield ratio. The observed stoichiometry of phytoplankton, however, has been shown to considerably vary from Redfield values due to plasticity in the expression of phytoplankton cell structures with different elemental compositions. The intrinsic structure of fixed C:N:P models therefore has the potential to bias projections of the marine response to climate change. We assess the importance of variable stoichiometry on 21st century projections of net primary production, food quality, and ocean carbon uptake using the recently developed Pelagic Interactions Scheme for Carbon and Ecosystem Studies Quota (PISCES-QUOTA) ocean biogeochemistry model. The model simulates variable phytoplankton C:N:P stoichiometry and was run under historical and business-as-usual scenario forcing from 1850 to 2100. PISCES-QUOTA projects similar 21st century global net primary production decline (7.7%) to current generation fixed stoichiometry models. Global phytoplankton N and P content or food quality is projected to decline by 1.2% and 6.4% over the 21st century, respectively. The largest reductions in food quality are in the oligotrophic subtropical gyres and Arctic Ocean where declines by the end of the century can exceed 20%. Using the change in the carbon export efficiency in PISCES-QUOTA, we estimate that fixed stoichiometry models may be underestimating 21st century cumulative ocean carbon uptake by 0.5-3.5% (2.0-15.1 PgC).

    The objective of the GeoCarbone-Injectivity project was to develop a methodology to study the complex phenomena involved in the near well bore region during CO 2 injection. This paper presents an overview of the program and results of the project, and some further necessary developments. The proposed methodology is based on experiments and simulations at the core scale, in order to understand (physical modelling and definition of constitutive laws) and quantify (calibration of simulation tools) the mechanisms involved in injectivity variations: fluid/rock interactions, transport mechanisms, geomechanical effects. These mechanisms and the associated parameters have then to be integrated in the models at the well bore scale. The methodology has been applied for the study of a potential injection of CO 2 in the Dogger geological formation of the Paris Basin, in collaboration with the other ANR GeoCarbone projects.

    Full Text Available Forest plantations are considered the main carbon sinks thought to reduce the impact of climate change. Regarding many species, however, there is a lack of information in order to establish metrics on accumulation of biomass and carbon, principally due to the level of difficulty and the cost of quantification through direct measurement and destructive sampling. In this research, it was evaluated carbon stocks of forest plantations near the dam of hydroelectric project Cachí, which belongs to Instituto Costarricense de Electricidad. 25 unit samples were evaluated along some plantations that contain three different species. 30 Pinus caribacea trees, 14 Cupressus lusitanica and 15 Eucalyptus deglupta were extracted. The biomass was quantified by means of the destructive method. First of all, every component of the tree was weighed separately; then, sampling was obtained in order to determine the dry matter and the carbon fraction. 110 biomass samples from the three species were analyzed in laboratory, including all the components (leaves, branches, shaft, and root. The carbon fraction varied between 47,5 and 48,0 for Pinus caribacea; between 32,6 and 52,7 for Cupressus lusitanica, and beween 36,4 and 50,3% for Eucalyptus deglupta. The stored carbon was 230, 123, and 69 Mg ha-1 in plantations of P. caribaea, C. lusitanica and E. deglupta, respectively. Approximately, 75% of the stored carbon was detected in the shaft.

  3. Essays on information disclosure and the environment

    Science.gov (United States)

    Mathai, Koshy

    The essays in this dissertation study information disclosure and environmental policy. The first chapter challenges the longstanding result that firms will, in general, voluntarily disclose information about product quality, in light of the unrealism of the assumption, common to much of the literature, that consumers are identical. When this assumption is relaxed, an efficiency-enhancing role may emerge for disclosure regulation, insofar as it can improve information provision and thus help protect consumers with "moderately atypical" preferences. The paper also endogenizes firms's choice of quality and suggests that disclosure regulation may also raise welfare indirectly, by inducing firms to improve product quality. The second chapter explores the significance of policy-induced technological change (ITC) for the design of carbon-abatement policies. The paper considers both R&D-based and learning-by-doing-based knowledge accumulation, examining each specification under both a cost-effectiveness and a benefit-cost policy criterion. We show analytically that the presence of ITC generally implies a lower profile of optimal carbon taxes, a shifting of abatement effort into the future (in the R&D scenarios), and an increase in the scale of abatement (in the benefit-cost scenarios). Numerical simulations indicate that the impact of ITC on abatement timing is very slight, but the effects on costs, optimal carbon taxes, and cumulative abatement can be large. The third chapter uses a World Bank dataset on Chinese state-owned enterprises to estimate price elasticities of industrial coal demand. A simple coal-demand equation is estimated in many forms, and significant price sensitivity is almost always found: the own-price elasticity is estimated to be roughly -0.5. A cost-function/share-equation system is also estimated, and although the function is frequently ill-behaved, indicating that firms may not be minimizing costs, the elasticity estimates again are large and

    A field-scale carbon dioxide (CO2) injection pilot project was conducted by the Southeast Regional Sequestration Partnership (SECARB) at Cranfield, Mississippi. Two associated campaigns in 2009 and 2010 were carried out to co-inject perfluorocarbon tracers (PFTs) and sulfur hexafluoride (SF6) with CO2. Tracers in gas samples from two observation wells were analyzed to construct breakthrough curves. We present the compiled field data as well as detailed numerical modeling of the flow and transport of CO2, brine, and introduced tracers. A high-resolution static model of the formation geology in the Detailed Area Study (DAS) was used in order to capture the impact of connected flow pathways created by fluvial channels on breakthrough curves and breakthrough times of PFTs and SF6 tracers. We use the cubic-plus-association (CPA) equation of state, which takes into account the polar nature of water molecules, to describe the phase behavior of CO2-brine-tracer mixtures. We show how the combination of multiple tracer injection pulses with detailed numerical simulations provide a powerful tool in constraining both formation properties and how complex flow pathways develop over time.

  5. Carbon Footprint Estimation Tool for Residential Buildings for Non-Specialized Users: OERCO2 Project

    2018-04-01

    Full Text Available Existing tools for environmental certification of buildings are failing in their ability to reach the general public and to create social awareness, since they require not only specialized knowledge regarding construction and energy sources, but also environmental knowledge. In this paper, an open-source online tool for the estimation of the carbon footprint of residential buildings by non-specialized users is presented as a product from the OERCO2 Erasmus + project. The internal calculations, data management and operation of this tool are extensively explained. The ten most common building typologies built in the last decade in Spain are analysed by using the OERCO2 tool, and the order of magnitude of the results is analysed by comparing them to the ranges determined by other authors. The OERCO2 tool proves itself to be reliable, with its results falling within the defined logical value ranges. Moreover, the major simplification of the interface allows non-specialized users to evaluate the sustainability of buildings. Further research is oriented towards its inclusion in other environmental certification tools and in Building Information Modeling (BIM environments.

  8. Corn Belt soil carbon and macronutrient budgets with projected sustainable stover harvest

    2015-01-01

    Corn (Zea mays L.) stover has been identified as a prime feedstock for biofuel production in the U.S. Corn Belt because of its perceived abundance and availability, but long-term stover harvest effects on regional nutrient budgets have not been evaluated. We defined the minimum stover requirement (MSR) to maintain current soil organic carbon levels and then estimated current and future soil carbon (C), nitrogen (N), phosphorus (P), and potassium (K) budgets for various stover harvest scenarios. Analyses for 2006 through 2010 across the entire Corn Belt indicated that currently, 28 Tg or 1.6 Mg ha−1 of stover could be sustainably harvested from 17.95 million hectares (Mha) with N, P, and K removal of 113, 26, and 47 kg ha−1, respectively, and C removal for that period was estimated to be 4.55 Mg C ha−1. Assuming continued yield increases and a planted area of 26.74 Mha in 2050, 77.4 Tg stover (or 2.4 Mg ha−1) could be sustainably harvested with N, P, and K removal of 177, 37, and 72 kg ha−1, respectively, along with C removal of ∼6.57 Mg C ha−1. Although there would be significant variation across the region, harvesting only the excess over the MSR under current fertilization rates would result in a small depletion of soil N (−5 ± 27 kg ha−1) and K (−20 ± 31 kg ha−1) and a moderate surplus of P (36 ± 18 kg ha−1). Our 2050 projections based on continuing to keep the MSR, but having higher yields indicate that soil N and K deficits would become larger, thus emphasize the importance of balancing soil nutrient supply with crop residue removal.

    Carbon (C) offset projects through forestation are employed within the emissions trading framework to store C. Yet, information about the potential of landscapes to stock C, essential to the design of offset projects, is often lacking. Based on data on vegetation C, climate and soil we quantified...... the potential for C storage in woody vegetation across tropical Africa. The ability for offset projects to produce co-benefits for ecosystems and local communities was also investigated. When co-benefits such as biodiversity conservation were considered, the top-ranked sites were often different to sites...... selected purely for their C stocking potential, but they still possessed 68% of the latter’s C stocking potential. This work provides the first continental-scale assessment of which areas may provide the greatest direct and indirect benefits from C storage reforestation projects at the smallest costs...

    Changes in climate and land use, caused by socio-economic changes, greenhouse gas emissions, agricultural policies and other factors, are known to affect both natural and managed ecosystems, and will likely impact on the European terrestrial carbon balance during the coming decades. This study presents a comprehensive European Union wide (EU15 plus Norway and Switzerland, EU*) assessment of potential future changes in terrestrial carbon storage considering these effects based on four illustrative IPCC-SRES story-lines (A1FI, A2, B1, B2). A process-based land vegetation model (LPJ-DGVM), adapted to include a generic representation of managed ecosystems, is forced with changing fields of land-use patterns from 1901 to 2100 to assess the effect of land-use and cover changes on the terrestrial carbon balance of Europe. The uncertainty in the future carbon balance associated with the choice of a climate change scenario is assessed by forcing LPJ-DGVM with output from four different climate models (GCMs: CGCM2, CSIRO2, HadCM3, PCM2) for the same SRES story-line. Decrease in agricultural areas and afforestation leads to simulated carbon sequestration for all land-use change scenarios with an average net uptake of 17-38 Tg C/year between 1990 and 2100, corresponding to 1.9-2.9% of the EU*s CO 2 emissions over the same period. Soil carbon losses resulting from climate warming reduce or even offset carbon sequestration resulting from growth enhancement induced by climate change and increasing atmospheric CO 2 concentrations in the second half of the twenty-first century. Differences in future climate change projections among GCMs are the main cause for uncertainty in the cumulative European terrestrial carbon uptake of 4.4-10.1 Pg C between 1990 and 2100. (authors)

    Full Text Available Turkey is an Annex-I country under the United Nations Framework Convention on Climate Change (UNFCCC and therefore submits its Greenhouse gases (GHG emissions and removals from anthropogenic sources to the UNFCCC secretariat on an annual basis, through a National GHG Inventory Report (NIR. GHG emissions and removals from Land Use, Land Use and Forestry (LULUCF constitute one of the main sectors in this report. One of the major land use categories in this sector is Forestland, and harvests in this category must be considered as a direct GHG emission to the atmosphere, unless the fate of the Harvested Wood Products (HWP is reported. In this study, we estimated the carbon sequestration in the HWP category of the Turkish NIR, according to the 2006 Guidelines for GHG inventory in the Agriculture, Forestry and Other Land Use (AFOLU sector, from the International Panel of Experts on Climate Change (IPCC. This is the first time such an estimate of carbon stocks and carbon stock changes in the HWP pool has been carried out in Turkey. The calculation has been done in Tier 2. We used United Nations Economic Commission for Europe (UNECE Timber database disaggregated figures for HWP produced in Turkey from 1964 to 2013. We focused on the two main HWP categories, which are sawnwood and wood-based panels. Comparing UNECE data series with Orman Genel Müdürlügü (OGM, the Republic of Turkey, General Directorate of Forestry data series for industrial roundwood over 1976-2013 (starting date for OGM data series, we noticed some anomalies (with UNECE data series as a basis: max: +47%, min = -23%, mean = +16%. Thus, the UNECE data on sawnwood and wood based panels were corrected based on OGM data. These anomalies could be due to: (i use of volume over bark for UNECE and volume under bark for OGM (+15% for volume over bark, and (ii integration of industrial roundwood coming from the private sector for UNECE. In order to ensure coherence, we then corrected the 1976

    This assessment was conducted to fulfill the requirements of section 712 of the Energy Independence and Security Act (EISA) of 2007 and to improve understanding of carbon and greenhouse gas (GHG) fluxes in the Great Plains region in the central part of the United States. The assessment examined carbon storage, carbon fluxes, and other GHG fluxes (methane and nitrous oxide) in all major terrestrial ecosystems (forests, grasslands/shrublands, agricultural lands, and wetlands) and freshwater aquatic systems (rivers, streams, lakes, and impoundments) in two time periods: baseline (generally in the first half of the 2010s) and future (projections from baseline to 2050). The assessment was based on measured and observed data collected by the U.S. Geological Survey (USGS) and many other agencies and organizations and used remote sensing, statistical methods, and simulation models.

    As societies move towards increased valuation of carbon through markets, regulations, and voluntary agreements the need to develop comprehensive, traceable and continuous, carbon monitoring, reporting and verification (MRV) systems has risen in priority locally to globally. Future landuse decisions, to conserve, develop or reforest, rests on the perceived valuation of anthropogenic and ecological benefits, as well as our ability to measure, report, verify, and "project" those benefits. Two carbon markets in the US, the Regional Green House Gas Initiative (RGGI) and the California Cap and Trade, accept carbon credits or offsets from the forestry sector from avoided emissions through forest conservation, by the enhancement land carbon sequestration through improved forest management and through reforestation projects. These investments often go beyond state, and national boundaries. For example, Blue Source a leading investment firm in forest carbon credits invested in over 20,000 acres of Pennsylvania forests in collaboration with The Nature Conservatory (TNC) Forest Conservation Program. Further local to national governments are writing their own climate policies and regulations and are setting targets for forest carbon storage and sequestration as part of their climate action portfolios. Yet, often little resources or effort is left for monitoring the success of projects such as afforestation initiatives once they have been completed. While field data is critical to monitoring efforts, covering the vast areas needed and getting accurate structural information from field campaigns alone can be difficult and costly. The use of Lidar as a supplement to other developed forest monitoring techniques has advanced significantly over the last decade. Here we evaluate the use of single photon lidar (SPL) collected in the summer of 2015, developed for rapidly collecting high-density, three-dimensional data over a variety of terrain targets, to aid in carbon offset MRV on an

    2016-03-01

    Full Text Available Recent studies suggest that climate change will lead to the local extinction of many tree species from large areas during this century, affecting the functioning and ecosystem services of many forests. This study reports on projected carbon losses due to the assumed local climate change-driven extinction of European beech (Fagus sylvatica L. from Zala County, South-Western Hungary, where the species grows at the xeric limit of its distribution. The losses were calculated as a difference between carbon stocks in climate change scenarios assuming an exponentially increasing forest decline over time, and those in a baseline scenario assuming no climate change. In the climate change scenarios, three different sets of forest management adaptation measures were studied: (1 only harvesting damaged stands, (2 additionally salvaging dead trees that died due to climate change, and (3 replacing, at an increasing rate over time, beech with sessile oak (Quercus petraea Matt. Lieb. after final harvest. Projections were made using the open access carbon accounting model CASMOFOR based on modeling or assuming effects of climate change on mortality, tree growth, root-to-shoot ratio and decomposition rates. Results demonstrate that, if beech disappears from the region as projected by the end of the century, over 80% of above-ground biomass carbon, and over 60% of the carbon stocks of all pools (excluding soils of the forests will be lost by 2100. Such emission rates on large areas may have a discernible positive feedback on climate change, and can only partially be offset by the forest management adaptation measures.

  1. Uncertainty in climate-carbon-cycle projections associated with the sensitivity of soil respiration to temperature

    International Nuclear Information System (INIS)

    Jones, Chris D.; Cox, Peter; Huntingford, Chris

    2003-01-01

    Carbon-cycle feedbacks have been shown to be very important in predicting climate change over the next century, with a potentially large positive feedback coming from the release of carbon from soils as global temperatures increase. The magnitude of this feedback and whether or not it drives the terrestrial carbon cycle to become a net source of carbon dioxide during the next century depends particularly on the response of soil respiration to temperature. Observed global atmospheric CO 2 concentration, and its response to naturally occurring climate anomalies, is used to constrain the behaviour of soil respiration in our coupled climate-carbon-cycle GCM. This constraint is used to quantify some of the uncertainties in predictions of future CO 2 levels. The uncertainty is large, emphasizing the importance of carbon-cycle research with respect to future climate change predictions

  2. A Conceptual Model for Projecting Coccolithophorid Growth, Calcification and Photosynthetic Carbon Fixation Rates in Response to Global Ocean Change

    Directory of Open Access Journals (Sweden)

    Natasha A. Gafar

    2018-01-01

    Full Text Available Temperature, light and carbonate chemistry all influence the growth, calcification and photosynthetic rates of coccolithophores to a similar degree. There have been multiple attempts to project the responses of coccolithophores to changes in carbonate chemistry, but the interaction with light and temperature remains elusive. Here we devise a simple conceptual model to derive a fit equation for coccolithophorid growth, photosynthetic and calcification rates in response to simultaneous changes in carbonate chemistry, temperature and light conditions. The fit equation is able to account for up to 88% of the variability in measured metabolic rates. Equation projections indicate that temperature, light and carbonate chemistry all have different modulating effects on both optimal growth conditions and the sensitivity of responses to extreme environmental conditions. Calculations suggest that a single extreme environmental condition (CO2, temperature, light will reduce maximum rates regardless of how optimal the other environmental conditions may be. Thus, while the response of coccolithophores to ocean change depends on multiple variables, the one which is least optimal will have the most impact on overall rates. Finally, responses to ocean change are usually reported in terms of cellular rates. However, changes in cellular rates can be a poor predictor for assessing changes in production at the community level. We therefore introduce a new metric, the calcium carbonate production potential (CCPP, which combines the independent effects of changes in growth rate and cellular calcium carbonate content to assess how environmental changes will impact coccolith production. Direct comparison of CO2 impacts on cellular CaCO3 production rates and CCPP shows that while the former is still at 45% of its pre-industrial capacity at 1,000 μatm, the latter is reduced to 10%.

    It is important to understand the fate of carbon in boreal peatland soils in response to climate change because a substantial change in release of this carbon as CO2 and CH4 could influence the climate system. The goal of this research was to synthesize the results of a field water table manipulation experiment conducted in a boreal rich fen into a process-based model to understand how soil organic carbon (SOC) of the rich fen might respond to projected climate change. This model, the peatland version of the dynamic organic soil Terrestrial Ecosystem Model (peatland DOS-TEM), was calibrated with data collected during 2005-2011 from the control treatment of a boreal rich fen in the Alaska Peatland Experiment (APEX). The performance of the model was validated with the experimental data measured from the raised and lowered water-table treatments of APEX during the same period. The model was then applied to simulate future SOC dynamics of the rich fen control site under various CO2 emission scenarios. The results across these emissions scenarios suggest that the rate of SOC sequestration in the rich fen will increase between year 2012 and 2061 because the effects of warming increase heterotrophic respiration less than they increase carbon inputs via production. However, after 2061, the rate of SOC sequestration will be weakened and, as a result, the rich fen will likely become a carbon source to the atmosphere between 2062 and 2099. During this period, the effects of projected warming increase respiration so that it is greater than carbon inputs via production. Although changes in precipitation alone had relatively little effect on the dynamics of SOC, changes in precipitation did interact with warming to influence SOC dynamics for some climate scenarios. © 2012 Blackwell Publishing Ltd.

To address this issue, orthopaedic societies have implemented a variety of guidelines related to potential conflict-of-interest disclosure. Transparency is crucial to address the concerns about potential conflict-of-interest disclosure. Nonetheless, prior studies have noted substantial discrepancies in disclosures to societies for individual authors who present their research work at multiple conferences. Our goal was to evaluate the ability of orthopaedic surgeons to interpret disclosure policy statements regarding project-specific or global disclosure instructions. The disclosure policy statements of the ten conferences most frequently attended by this group were collected, and selected statements were compiled into a questionnaire survey that was administered to orthopaedic faculty and trainees at our institution. Subjects were asked to read each statement and identify whether they interpreted the policy to be requesting project-specific disclosures (potential conflict of interest related to the research work in the abstract being submitted) or global disclosure (inclusive of all potential conflicts of interest, including those not associated with the abstract being submitted). The correct responses were identified by communicating with the individual societies and determining the responses desired by the society. The study had a 100% return rate from seventeen orthopaedic faculty, twenty-five orthopaedic residents and fellows, and twenty-five medical students. The average number of incorrect responses to the ten questions was 2.8. Forty-six percent of respondents had three or more incorrect responses, 24% had two incorrect responses, 19% had one incorrect response, and 10% had no incorrect responses. There was no significant difference in responses between those of different training levels. Subjects were no more likely to answer a project-specific question incorrectly than they

    The conversion of land from its native state to an agricultural use commonly results in a significant loss of soil carbon (Mann, 1985; Davidson and Ackerman, 1993). Globally, this loss is estimated to account for as much as 1/3 of the net CO2 emissions for the period of 1850 to 1980 (Houghton and others, 1983). Roughly 20 to 40 percent of original soil carbon is estimated to be lost as CO2 as a result of agricultural conversion, or "decomposition enhancement". Global models use this estimate along with land conversion data to provide agricultural contributions of CO2 emissions for global carbon budgets (Houghton and others, 1983; Schimel, 1995). Soil erosion rates are significantly (10X) higher on croplands than on their undisturbed equivalents (Dabney and others, 1997). Most of the concern over erosion is related to diminished productivity of the uplands (Stallings, 1957; McGregor and others, 1969; Rhoton, 1990) or to increased hazards and navigability of the lowlands in the late 1800's to early 1900's. Yet because soil carbon is concentrated at the soil surface, with an exponential decline in concentration with depth (Harden et al, 1999), it is clear that changes in erosion rates seen on croplands must also impact soil carbon storage and terrestrial carbon budgets as well. As yet, erosional losses of carbon are not included in global carbon budgets explicitly as a factor in land conversion nor implicitly as a portion of the decomposition enhancement. However, recent work by Lal and others (1995) and by Stallard (1998) suggests that significant amounts of eroded soil may be stored in man-made reservoirs and depositional environments as a result of agricultural conversion. Moreover, Stallard points out that eroding soils have the potential for replacing part of the carbon trapped in man-made reservoirs. If true, then the global carbon budget may grossly underestimate or ignore a significant sink term resulting from the burial of eroded soil.

  11. The Role of Theory in Explaining Motivation for Corporate Social Disclosures: Voluntary Disclosures vs ‘Solicited’ Disclosures

    2009-12-01

    Full Text Available Corporate social disclosures (CSD are primarily voluntary in nature and subsequently provide an area forresearch into motivational aspects of disclosures. The main focus of prior research has been whethercorporate social disclosures constitute a discharge of accountability or are part of a process of legitimation.Prior research, however, ignores the emergence of an alternate style of corporate social disclosure, the‘solicited’ disclosure. Increasingly companies are requested to report on their interactions with society invarious forms. Non-government organisations (NGOs, regulatory agencies, ethical or socially responsibleinvestment fund managers and other researchers are requesting social information from corporations. Thisshift from voluntary information provision to demanded information can be viewed as a natural consequenceof the increasing pressures on corporations to be ‘responsible’, particularly in light of intensified world wideattention on unethical corporate behaviour and corporate collapse. These contemporary variants of socialdisclosure are worthy of scrutiny when considering these ‘solicited’ disclosures potentially reduce acorporation’s power in defining the scope and nature of disclosures. Two theories, which are similar andderived from the broader political economy perspective, are commonly offered as explanations of motivationsfor social disclosures. Stakeholder theory offers an explanation of accountability to stakeholders. Legitimacytheory, on the other hand, suggests voluntary disclosures are part of a process of legitimation. This paperargues that these theoretical perspectives may provide greater insights into managerial motivation fordisclosure if they are linked more explicitly to the nature of corporate social disclosure under examination:voluntary or solicited.

    As automotive fuel economy requirements increase, the push for reducing overall vehicle weight will likely include the consideration of materials that have not previously been part of mainstream vehicle design and manufacturing, including carbon fiber composites. Vehicle manufacturers currently rely on computer-aided engineering (CAE) methods as part of the design and development process, so going forward, the ability to accurately and predictably model carbon fiber composites will be necessary. If composites are to be used for structural components, this need applies to both, crash and quasi-static modeling. This final report covers the results of a five-year, $6.89M, 50% cost-shared research project between Department of Energy (DOE) and the US Advanced Materials Partnership (USAMP) under Cooperative Agreement DE-EE-0005661 known as “Validation of Material Models for Automotive Carbon Fiber Composite Structures Via Physical and Crash Testing (VMM).” The objective of the VMM Composites Project was to validate and assess the ability of physics-based material models to predict crash performance of automotive primary load-carrying carbon fiber composite structures. Simulation material models that were evaluated included micro-mechanics based meso-scale models developed by the University of Michigan (UM) and micro-plane models by Northwestern University (NWU) under previous collaborations with the DOE and Automotive Composites Consortium/USAMP, as well as five commercial crash codes: LS-DYNA, RADIOSS, VPS/PAM-CRASH, Abaqus, and GENOA-MCQ. CAE predictions obtained from seven organizations were compared with experimental results from quasi-static testing and dynamic crash testing of a thermoset carbon fiber composite front-bumper and crush-can (FBCC) system gathered under multiple loading conditions. This FBCC design was developed to demonstrate progressive crush, virtual simulation, tooling, fabrication, assembly, non-destructive evaluation and crash testing

  3. Quantifying the Carbon Balance of Forest Restoration and Wildfire under Projected Climate in the Fire-Prone Southwestern US.

    2017-01-01

    Climate projections for the southwestern US suggest a warmer, drier future and have the potential to impact forest carbon (C) sequestration and post-fire C recovery. Restoring forest structure and surface fire regimes initially decreases total ecosystem carbon (TEC), but can stabilize the remaining C by moderating wildfire behavior. Previous research has demonstrated that fire maintained forests can store more C over time than fire suppressed forests in the presence of wildfire. However, because the climate future is uncertain, I sought to determine the efficacy of forest management to moderate fire behavior and its effect on forest C dynamics under current and projected climate. I used the LANDIS-II model to simulate carbon dynamics under early (2010-2019), mid (2050-2059), and late (2090-2099) century climate projections for a ponderosa pine (Pinus ponderosa) dominated landscape in northern Arizona. I ran 100-year simulations with two different treatments (control, thin and burn) and a 1 in 50 chance of wildfire occurring. I found that control TEC had a consistent decline throughout the simulation period, regardless of climate. Thin and burn TEC increased following treatment implementation and showed more differentiation than the control in response to climate, with late-century climate having the lowest TEC. Treatment efficacy, as measured by mean fire severity, was not impacted by climate. Fire effects were evident in the cumulative net ecosystem exchange (NEE) for the different treatments. Over the simulation period, 32.8-48.9% of the control landscape was either C neutral or a C source to the atmosphere and greater than 90% of the thin and burn landscape was a moderate C sink. These results suggest that in southwestern ponderosa pine, restoring forest structure and surface fire regimes provides a reasonable hedge against the uncertainty of future climate change for maintaining the forest C sink.

    There is a dilemma for rapid industrializing China to balance economic growth and low carbonization. Industrial symbiosis (IS) provides a system innovation to utilize the industry to fight climate change and pursue sustainable urban development, while few attentions are paid in literatures. Under this circumstance, this study reviews the low-carbon city practice in China and conducts a case study to calculate the CO 2 emissions reduction potential under promoting IS projects in two cities of China, named Jinan and Liuzhou. With the real national project in Jinan as advanced example, new scenarios related to IS are designed for Liuzhou, including comprehensive energy network, waste plastics recycling, scrap tires recycling and flying ash recycling. The material/waste and energy exchange is quantified in the IS network, as well as the related environmental benefit. The material/energy exchange is over 10 million ton and 20 thousands tce in Jinan's case, and 2.5 million ton and 45 thousand tce in Liuzhou's case. Results highlight that IS could effectively reduce CO 2 emissions. The total reduction potential amounts to 3944.05 thousands tCO 2 /year and 2347.88 thousands tCO 2 /year in Jinan and Liuzhou. Finally, policy implications on the ever-improvement of industrial symbiosis and China's sustainable urban development are proposed and discussed. - Highlights: • Investigate two real industrial symbiosis projects in Jinan and Liuzhou of China. • Quantify the material exchange and the CO 2 reduction potential of the IS network. • CO 2 reduction potential is 3944.05 and 2347.88 ktCO 2 /year in Jinan and Liuzhou. • In current China, IS is main in term of material symbiosis. • How to coordinate IS and low-carbon city is discussed

    Full Text Available The aim of this study is to examine the corporate governance influence on strategic management accounting disclosure. The strategic management accounting disclosure in this study was measured by the disclosure level regarding strategic management accounting published in the company's annual report according to the index (made by the author. The corporate governance is proxied by board size, independent board, and managerial ownership. The data of this study are 497 manufacturing companies in Indonesia in the period of 2011-2015 and the method employed in this study is regression analysis method. The findings show that board size has significant positive influence on the disclosure level of strategic management accounting of manufacturing companies in Indonesia, and the proportion of independent board does not influence SMA disclosure, while managerial ownership has negative influence the disclosure level of strategic management accounting.

  8. Some Thoughts on Self-Disclosure.

    Science.gov (United States)

    Richards, Arnold

    2018-04-01

    This paper explores the pros and cons of self-disclosure and self revelation in the analyst. It takes as its starting point a paper by Jeffrey Stern that shows a mixed but generally positive outcome of an incident of self-disclosure. The trend in more recent times has been toward somewhat more self-disclosure, with modern analysts' views on a continuum. The author discusses an example from his own practice, in which he delayed self-disclosure for some time, but did reveal facts about himself, and how this had a mostly positive outcome. He concludes by distinguishing self-disclosure that entails stating facts about self from self-revelation, when the analyst tells his feelings about some specifics from his own life or in the patient's disclosure. Such revelation is not likely to be beneficial to the therapeutic alliance in its early stages, but may be of value as the analytic relationship and trust develop over longer time.

    Nowadays, GHG emission is a critical issue for environmental management due to the large scale of land cover change, especially forest cover. This study provides a protection development strategy for North Sumatera as one way to manage the area. By using Multi Objective Land Allocation (MOLA), we evaluated two GHG emission scenarios, including a Business As Usual (BAU) scenario and Protection scenario. The result shows that the province will lose the carbon stock up to 24 million tons in the year of 2035 by using a BAU scenario. On the other hand, by implementing the Protection scenario, total carbon stock that is lost in the same period is about 5 millions tons solely. It proves that protection scenario is a good scenario and effective to reduce the carbon loss. Furthermore, this scenario can be an alternative for North Sumatera spatial plan.

    1993-01-01

    The therapeutic use of countertransference disclosure as a means of highlighting the borderline patient's intrapsychic and interpersonal use of the therapist is discussed.Countertransference disclosure is narrowly defined as a form of clinical honesty that focuses on the therapist's experience of the patient in the here-and-now moment of the session. The effects of disclosure on transference exploration, neutrality, and patient revelations are explored through examination of detailed process notes of therapy sessions.Technical issues such as indirect versus direct disclosure and responses to direct questions are also addressed.

  19. Implementation of forest cover and carbon mapping in the Greater Mekong subregion and Malaysia project - A case study of Thailand

    2014-02-01

    The Great Mekong Subregion (GMS) contains one of the world's largest tropical forests and plays a vital role in sustainable development and provides a range of economic, social and environmental benefits, including essential ecosystem services such as climate change mitigation and adaptation. However, the forest in this Subregion is experiencing deforestation rates at high level due to human activities. The reduction of the forest area has negative influence to the environmental and natural resources issues, particularly, more severe disasters have occurred due to global warming and the release of the greenhouse gases. Therefore, in order to conduct forest management in the Subregion efficiently, the Forest Cover and Carbon Mapping in Greater Mekong Subregion and Malaysia project was initialized by the Asia-Pacific Network for Sustainable Forest Management and Rehabilitation (APFNet) with the collaboration of various research institutions including Institute of Forest Resource Information Technique (IFRIT), Chinese Academy of Forestry (CAF) and the countries in Sub region and Malaysia comprises of Cambodia, the People's Republic of China (Yunnan province and Guangxi province), Lao People's Democratic Republic, Malaysia, Myanmar, Thailand, and Viet Nam. The main target of the project is to apply the intensive use of recent satellite remote sensing technology, establishing regional forest cover maps, documenting forest change processes and estimating carbon storage in the GMS and Malaysia. In this paper, the authors present the implementation of the project in Thailand and demonstrate the result of forest cover mapping in the whole country in 2005 and 2010. The result of the project will contribute towards developing efficient tools to support decision makers to clearly understand the dynamic change of the forest cover which could benefit sustainable forest resource management in Thailand and the whole Subregion.

    The CO 2 injected into deep formations during implementation of carbon dioxide (CO 2 ) capture and storage (CCS) technology may leak and migrate into shallow aquifers or ground surfaces through a variety of pathways over a long period. The leaked CO 2 can threaten shallow environments as well as human health. Therefore, almost all monitoring programs for CCS projects around the world contain near-surface monitoring. This paper presents a U-tube based near-surface monitoring technology focusing on its first application in the Shenhua CCS demonstration project, located in the Ordos Basin, Inner Mongolia, China. First, background information on the site monitoring program of the Shenhua CCS demonstration project was provided. Then, the principle of fluid sampling and the monitoring methods were summarized for the U-tube sampler system, and the monitoring data were analyzed in detail. The U-tube based monitoring results showed that the U-tube sampler system is accurate, flexible, and representative of the subsurface fluid sampling process. The monitoring indicators for the subsurface water and soil gas at the Shenhua CCS site indicate good stratification characteristics. The concentration level of each monitoring indicator decreases with increasing depth. Finally, the significance of this near-surface environmental monitoring technology for CO 2 leakage assessments was preliminarily confirmed at the Shenhua CCS site. The application potential of the U-tube based monitoring technology was also demonstrated during the subsurface environmental monitoring of other CCS projects.

    The long-term stressful utilization of forests and grasslands has led to ecosystem degradation and C loss. Since the late 1970s China has launched six key national ecological restoration projects to protect its environment and restore degraded ecosystems. Here, we conducted a large-scale field investigation and a literature survey of biomass and soil C in China's forest, shrubland, and grassland ecosystems across the regions where the six projects were implemented (∼16% of the country's land area). We investigated the changes in the C stocks of these ecosystems to evaluate the contributions of the projects to the country's C sink between 2001 and 2010. Over this decade, we estimated that the total annual C sink in the project region was 132 Tg C per y (1 Tg = 10 12 g), over half of which (74 Tg C per y, 56%) was attributed to the implementation of the projects. Our results demonstrate that these restoration projects have substantially contributed to CO 2 mitigation in China.

    Northern peatlands represent a globally significant pool of carbon and are subject to the highest rates of climate warming, and most of these peatlands are in continental settings. However, it is unclear if how fast peatlands respond to past and present changes in temperature and surface moisture in continental vs. oceanic climate settings. The CLIMPEAT project brings together scientists from Poland and Switzerland. Our goal is to assess the past and present vulnerability to climate change of Sphagnum peatland plant and microbial communities, peat organic matter transformations and carbon sequestration using a combination of field and mesocosm experiments simulating warming and water table changes and palaeoecological studies. Warming will be achieved using ITEX-type "Open-Top Chambers". The field studies are conducted in Poland, at the limit between oceanic and continental climates, and are part of a network of projects also including field experiments in the French Jura (sub-oceanic) and in Siberia (continental). We will calibrate the response of key biological (plants, testate amoebae) and geochemical (isotopic composition of organic compounds, organic matter changes) proxies to warming and water table changes and use these proxies to reconstruct climate changes during the last 1000 years.

  12. Ocean acidification over the next three centuries using a simple global climate carbon-cycle model: projections and sensitivities

    Energy Technology Data Exchange (ETDEWEB)

    2016-08-01

    Continued oceanic uptake of anthropogenic CO2 is projected to significantly alter the chemistry of the upper oceans over the next three centuries, with potentially serious consequences for marine ecosystems. Relatively few models have the capability to make projections of ocean acidification, limiting our ability to assess the impacts and probabilities of ocean changes. In this study we examine the ability of Hector v1.1, a reduced-form global model, to project changes in the upper ocean carbonate system over the next three centuries, and quantify the model's sensitivity to parametric inputs. Hector is run under prescribed emission pathways from the Representative Concentration Pathways (RCPs) and compared to both observations and a suite of Coupled Model Intercomparison (CMIP5) model outputs. Current observations confirm that ocean acidification is already taking place, and CMIP5 models project significant changes occurring to 2300. Hector is consistent with the observational record within both the high- (> 55°) and low-latitude oceans (< 55°). The model projects low-latitude surface ocean pH to decrease from preindustrial levels of 8.17 to 7.77 in 2100, and to 7.50 in 2300; aragonite saturation levels (ΩAr) decrease from 4.1 units to 2.2 in 2100 and 1.4 in 2300 under RCP 8.5. These magnitudes and trends of ocean acidification within Hector are largely consistent with the CMIP5 model outputs, although we identify some small biases within Hector's carbonate system. Of the parameters tested, changes in [H+] are most sensitive to parameters that directly affect atmospheric CO2 concentrations – Q10 (terrestrial respiration temperature response) as well as changes in ocean circulation, while changes in ΩAr saturation levels are sensitive to changes in ocean salinity and Q10. We conclude that Hector is a robust tool well suited for rapid ocean acidification

    The objective of the present study was to set up a small-scale pilot reactor at ONGC Hazira, Surat, for capturing CO 2 from vent gas. The studies were carried out for CO 2 capture by either using microalgae Chlorella sp. or a consortium of microalgae (Scenedesmus quadricauda, Chlorella vulgaris and Chlorococcum humicola). The biomass harvested was used for anaerobic digestion to produce biogas. The carbonation column was able to decrease the average 34 vol.% of CO 2 in vent gas to 15 vol.% of CO 2 in the outlet gas of the carbonation column. The yield of Chlorella sp. was found to be 18 g/m 2 /day. The methane yield was 386 l CH 4 /kg VS fed of Chlorella sp. whereas 228 l CH 4 /kg VS fed of the consortium of algae.

    Choi, Soe Yoon; Venetis, Maria K.; Greene, Kathryn; Magsamen-Conrad, Kate; Checton, Maria G.; Banerjee, Smita C.

    2016-01-01

    This study applied the disclosure decision-making model (DD-MM) to explore how individuals plan to disclose nonvisible illness (Study 1), compared to planning to disclose personal information (Study 2). Study 1 showed that perceived stigma from the illness negatively predicted disclosure efficacy; closeness predicted anticipated response (i.e., provision of support) although it did not influence disclosure efficacy; disclosure efficacy led to reduced planning, with planning leading to scheduling. Study 2 demonstrated that when information was considered to be intimate, it negatively influenced disclosure efficacy. Unlike the model with stigma (Study 1), closeness positively predicted both anticipated response and disclosure efficacy. The rest of the hypothesized relationships showed a similar pattern to Study 1: disclosure efficacy reduced planning, which then positively influenced scheduling. Implications of understanding stages of planning for stigmatized information are discussed. PMID:27662447

    2017-01-01

    With the advent of social networks where people disclose a lot of their information and opinions publicly, this research attempted to re-look at the effect of environmental lighting on willingness and actual disclosure of personal information. Previous literatures mostly addressed counseling setups and the findings were mixed. In order to clarify the effect of lighting on self-disclosure, two experiments were conducted with reported willingness to disclose (Experiment 1) as well as actual disclosure (Experiment 2) on a range of topics like social issues, body, money, work, and personality. While quite a handful of studies have reported differences in disclosure from very subtle environmental lighting manipulations, in both experiments we could not find any effect of ambient room lighting conditions on self-disclosure. These results call for caution both in over-interpreting subtle environmental effects and in increased generalization of perceptual metaphors to actual behavior.

    Full Text Available Corporate Social Responsibility (CSR has a very important role for the company and now become an obligation for every company. The purpose of this study examined the effect of institutional ownership, board of commissioners, profitability and size on CSR disclosure. This research conducted at mining manufacturing companies listed in Indonesia Stock Exchange period 2013-2014 and obtained 76 sample companies. The method used is multiple regression analysis. The result showed only institutional ownership affecting CSR disclosure. This suggests institutional ownership structure can act in monitoring the company. Independent board has not effected on CSR, it failed to monitor the actions of top management. Profitability has not effected on the disclosure of CSR, it enabled the company to have two perspectives on CSR. The most companies view CSR as a deduction from earnings. CSR disclosure has not affect the size of the CSR disclosure area.DOI: 10.15408/etk.v16i2.5236

  8. Risks to coral reefs from ocean carbonate chemistry changes in recent earth system model projections

    International Nuclear Information System (INIS)

    Ricke, K L; Caldeira, K; Orr, J C; Schneider, K

    2013-01-01

    Coral reefs are among the most biodiverse ecosystems in the world. Today they are threatened by numerous stressors, including warming ocean waters and coastal pollution. Here we focus on the implications of ocean acidification for the open ocean chemistry surrounding coral reefs, as estimated from earth system models participating in the Coupled Model Intercomparison Project, Phase 5 (CMIP5). We project risks to reefs in the context of three potential aragonite saturation (Ωa) thresholds. We find that in preindustrial times, 99.9% of reefs adjacent to open ocean in the CMIP5 ensemble were located in regions with Ωa > 3.5. Under a business-as-usual scenario (RCP 8.5), every coral reef considered will be surrounded by water with Ωa 2 emissions abatement, the Ωa threshold for reefs is critical to projecting their fate. Our results indicate that to maintain a majority of reefs surrounded by waters with Ωa > 3.5 to the end of the century, very aggressive reductions in emissions are required. The spread of Ωa projections across models in the CMIP5 ensemble is narrow, justifying a high level of confidence in these results. (letter)

    2017-12-01

    Human land-use activities have resulted in large changes to the Earth surface, with resulting implications for climate. In the future, land-use activities are likely to intensify to meet growing demands for food, fiber, and energy. The Land Use Model Intercomparison Project (LUMIP) aims to further advance understanding of the broad question of impacts of land-use and land-cover change (LULCC) as well as more detailed science questions to get at process-level attribution, uncertainty, and data requirements in more depth and sophistication than possible in a multi-model context to date. LUMIP is multi-faceted and aims to advance our understanding of land-use change from several perspectives. In particular, LUMIP includes a factorial set of land-only simulations that differ from each other with respect to the specific treatment of land use or land management (e.g., irrigation active or not, crop fertilization active or not, wood harvest on or not), or in terms of prescribed climate. This factorial series of experiments serves several purposes and is designed to provide a detailed assessment of how the specification of land-cover change and land management affects the carbon, water, and energy cycle response to land-use change. The potential analyses that are possible through this set of experiments are vast. For example, comparing a control experiment with all land management active to an experiment with no irrigation allows a multi-model assessment of whether or not the increasing use of irrigation during the 20th century is likely to have significantly altered trends of regional water and energy fluxes (and therefore climate) and/or crop yield and carbon fluxes in agricultural regions. Here, we will present preliminary results from the factorial set of experiments utilizing the Community Land Model (CLM5). The analyses presented here will help guide multi-model analyses once the full set of LUMIP simulations are available.

    Wetlands are critical terrestrial ecosystems in Alaska, covering ~177,000 km 2 , an area greater than all the wetlands in the remainder of the United States. To assess the relative influence of changing climate, atmospheric carbon dioxide (CO 2 ) concentration, and fire regime on carbon balance in wetland ecosystems of Alaska, a modeling framework that incorporates a fire disturbance model and two biogeochemical models was used. Spatially explicit simulations were conducted at 1 km-resolution for the historical period (1950-2009) and future projection period (2010-2099). Simulations estimated that wetland ecosystems of Alaska lost 175 Tg carbon (C) in the historical period. Ecosystem C storage in 2009 was 5556 Tg, with 89% of the C stored in soils. The estimated loss of C as CO 2 and biogenic methane (CH 4 ) emissions resulted in wetlands of Alaska increasing the greenhouse gas forcing of climate warming. Simulations for the projection period were conducted for six climate change scenarios constructed from two climate models forced under three CO 2 emission scenarios. Ecosystem C storage averaged among climate scenarios increased 3.94 TgC/yr by 2099, with variability among the simulations ranging from 2.02 to 4.42 TgC/yr. These increases were driven primarily by increases in net primary production (NPP) that were greater than losses from increased decomposition and fire. The NPP increase was driven by CO 2 fertilization (~5% per 100 ppmv increase) and by increases in air temperature (~1% per °C increase). Increases in air temperature were estimated to be the primary cause for a projected 47.7% mean increase in biogenic CH 4 emissions among the simulations (~15% per °C increase). Ecosystem CO 2 sequestration offset the increase in CH 4 emissions during the 21 st century to decrease the greenhouse gas forcing of climate warming. However, beyond 2100, we expect that this forcing will ultimately increase as wetland ecosystems transition from being a sink to a source

    This paper analyzes both the carbon fiber-based development for uranium centrifuges and the research project that supports its development effort over time. The carbon fibre-based engineering properties make it a valuable supply for high technological products, such as uranium ultracentrifuge. There is no production of such fibers in Brazil. Its trade is subject to international market restrictions due to carbon fibers' dual applications. The Centro Tecnologico da Marinha em Sao Paulo (CTMSP), the Universidade de Campinas (UNICAMP), the Universidade de Sao Paulo (USP), the RADICIFIBRAS Company, and the Financiadora de Estudos e Projetos (FINEP), which is responsible for the project financial support, established a partnership aiming the development of a domestic polyacrylonitrile (Pan)-based carbon fiber industry. Such alliances or technological partnerships are best known in developed countries, such as USA and Japan, as Cooperative Research or Research Joint Ventures (RJV). (author)

    It is important to understand how upland ecosystems of Alaska, which are estimated to occupy 84% of the state (i.e., 1,237,774 km2), are influencing and will influence state‐wide carbon (C) dynamics in the face of ongoing climate change. We coupled fire disturbance and biogeochemical models to assess the relative effects of changing atmospheric carbon dioxide (CO2), climate, logging and fire regimes on the historical and future C balance of upland ecosystems for the four main Landscape Conservation Cooperatives (LCCs) of Alaska. At the end of the historical period (1950–2009) of our analysis, we estimate that upland ecosystems of Alaska store ~50 Pg C (with ~90% of the C in soils), and gained 3.26 Tg C/yr. Three of the LCCs had gains in total ecosystem C storage, while the Northwest Boreal LCC lost C (−6.01 Tg C/yr) because of increases in fire activity. Carbon exports from logging affected only the North Pacific LCC and represented less than 1% of the state's net primary production (NPP). The analysis for the future time period (2010–2099) consisted of six simulations driven by climate outputs from two climate models for three emission scenarios. Across the climate scenarios, total ecosystem C storage increased between 19.5 and 66.3 Tg C/yr, which represents 3.4% to 11.7% increase in Alaska upland's storage. We conducted additional simulations to attribute these responses to environmental changes. This analysis showed that atmospheric CO2 fertilization was the main driver of ecosystem C balance. By comparing future simulations with constant and with increasing atmospheric CO2, we estimated that the sensitivity of NPP was 4.8% per 100 ppmv, but NPP becomes less sensitive to CO2increase throughout the 21st century. Overall, our analyses suggest that the decreasing CO2 sensitivity of NPP and the increasing sensitivity of heterotrophic respiration to air temperature, in addition to the increase in C loss from wildfires weakens the C sink from upland

    GE Global Research has developed, over the last 8 years, a platform of cost effective CO2 capture technologies based on a non-aqueous aminosilicone solvent (GAP-1m). As demonstrated in previous funded DOE projects (DE-FE0007502 and DEFE0013755), the GAP-1m solvent has increased CO2 working capacity, lower volatility and corrosivity than the benchmark aqueous amine technology. Performance of the GAP-1m solvent was recently demonstrated in a 0.5 MWe pilot at National Carbon Capture Center, AL with real flue gas for over 500 hours of operation using a Steam Stripper Column (SSC). The pilot-scale PSTU engineering data were used to (i) update the techno-economic analysis, and EH&S assessment, (ii) perform technology gap analysis, and (iii) conduct the solvent manufacturability and scale-up study.

    Materials such as coal, peat, or schist are subjected to a rising temperature in successive stages in apparatus in which the distillation products are withdrawn at each stage. For example in a three-stage process, the acid products of the first or low-temperature stage are fixed in a suitable reagent, the basic products from a second or higher-temperature stage are absorbed in an acid reagent, hydrocarbons being retained by solvents, while the third are subjected to a pyrogenation process carried out in a closed vessel. Wherein the material is subjected in stages to a rising temperature, the gasified products being withdrawn at each stage, and are prevented as far as possible from mixing with the carbonized products.

    Under this three year project, the condition of legacy oil and gas wells in the Midwest United States was evaluated through analysis of well records, well plugging information, CBL evaluation, sustained casing pressure (SCP) field testing, and analysis of hypothetical CO2 test areas to provide a realistic description of wellbore integrity factors. The research included a state-wide review of oil and gas well records for Ohio and Michigan, along with more detailed testing of wells in Ohio. Results concluded that oil and gas wells are clustered along fields in areas. Well records vary in quality, and there may be wells that have not been identified in records, but there are options for surveying unknown wells. Many of the deep saline formations being considered for CO2 storage have few wells that penetrate the storage zone or confining layers. Research suggests that a variety of well construction and plugging approaches have been used over time in the region. The project concluded that wellbore integrity is an important issue for CO2 storage applications in the Midwest United States. Realistic CO2 storage projects may cover an area in the subsurface with several hundred legacy oil and gas wells. However, closer inspection may often establish that most of the wells do not penetrate the confining layers or storage zone. Therefore, addressing well integrity may be manageable. Field monitoring of SCP also indicated that tested wells provided zonal isolation of the reservoirs they were designed to isolate. Most of these wells appeared to exhibit gas pressure originating from intermediate zones. Based on these results, more flexibility in terms of cementing wells to surface, allowing well testing, and monitoring wells may aid operators in completing CO2 storage project. Several useful products were developed under this project for examining wellbore integrity for CO2 storage applications including, a

  6. Friendship at work and error disclosure

    Full Text Available Organizations rely on contextual factors to promote employee disclosure of self-made errors, which induces a resource dilemma (i.e., disclosure entails costing one's own resources to bring others resources and a friendship dilemma (i.e., disclosure is seemingly easier through friendship, yet the cost of friendship is embedded. This study proposes that friendship at work enhances error disclosure and uses conservation of resources theory as underlying explanation. A three-wave survey collected data from 274 full-time employees with a variety of occupational backgrounds. Empirical results indicated that friendship enhanced error disclosure partially through relational mechanisms of employees’ attitudes toward coworkers (i.e., employee engagement and of coworkers’ attitudes toward employees (i.e., perceived social worth. Such effects hold when controlling for established predictors of error disclosure. This study expands extant perspectives on employee error and the theoretical lenses used to explain the influence of friendship at work. We propose that, while promoting error disclosure through both contextual and relational approaches, organizations should be vigilant about potential incongruence.

    This study explored Iranian patients' experiences of cancer disclosure, paying particular attention to the ways of disclosure. Twenty cancer patients were invited to participate in this qualitative inquiry by research staff in the clinical setting. In-depth, semistructured interview data were analyzed through content analysis. The rigor of the study was established by principles of credibility, transferability, dependability, and confirmability. Four themes emerged: the atmosphere of non-disclosure, eventual disclosure, distress in knowing, and the desire for information. Non-disclosure was the norm for participants, and all individuals involved made efforts to maintain an atmosphere of non-disclosure. While a select few were informed of their diagnosis by a physician or another patient, the majority eventually became aware of their diagnosis indirectly by different ways. All participants experienced distress after disclosure. The participants wanted basic information about their prognosis and treatments from their treating physicians, but did not receive this information, and encountered difficulty accessing information elsewhere. These challenges highlight the need for changes in current medical practice in Iran, as well as patient and healthcare provider education. © 2012 Blackwell Publishing Asia Pty Ltd.

    2017-07-01

    Full Text Available We report continuous surface observations of carbon dioxide (CO2 and methane (CH4 from the Los Angeles (LA Megacity Carbon Project during 2015. We devised a calibration strategy, methods for selection of background air masses, calculation of urban enhancements, and a detailed algorithm for estimating uncertainties in urban-scale CO2 and CH4 measurements. These methods are essential for understanding carbon fluxes from the LA megacity and other complex urban environments globally. We estimate background mole fractions entering LA using observations from four extra-urban sites including two marine sites located south of LA in La Jolla (LJO and offshore on San Clemente Island (SCI, one continental site located in Victorville (VIC, in the high desert northeast of LA, and one continental/mid-troposphere site located on Mount Wilson (MWO in the San Gabriel Mountains. We find that a local marine background can be established to within  ∼  1 ppm CO2 and  ∼  10 ppb CH4 using these local measurement sites. Overall, atmospheric carbon dioxide and methane levels are highly variable across Los Angeles. Urban and suburban sites show moderate to large CO2 and CH4 enhancements relative to a marine background estimate. The USC (University of Southern California site near downtown LA exhibits median hourly enhancements of  ∼  20 ppm CO2 and  ∼  150 ppb CH4 during 2015 as well as  ∼  15 ppm CO2 and  ∼  80 ppb CH4 during mid-afternoon hours (12:00–16:00 LT, local time, which is the typical period of focus for flux inversions. The estimated measurement uncertainty is typically better than 0.1 ppm CO2 and 1 ppb CH4 based on the repeated standard gas measurements from the LA sites during the last 2 years, similar to Andrews et al. (2014. The largest component of the measurement uncertainty is due to the single-point calibration method; however, the uncertainty in the background mole fraction is much

    Despite increasing attention to issues of patient safety, preventable adverse events (AEs) continue to occur, causing direct and consequential injuries to patients, families, and health care providers. Pediatricians generally agree that there is an ethical obligation to inform patients and families about preventable AEs and medical errors. Nonetheless, barriers, such as fear of liability, interfere with disclosure regarding preventable AEs. Changes to the legal system, improved communications skills, and carefully developed disclosure policies and programs can improve the quality and frequency of appropriate AE disclosure communications.

    2008-01-01

    Full Text Available Our paper deals with aspects regarding risk and uncertainty. Many risk management methods are today implemented in organizations. This perspective reveals that managers are linked in different forms to the activities they are managing, depending on the conditions and levels of uncertainty they are in. Actually, these multiple levels of uncertainty lead to the conclusion that any situation in an organizational system can be classified in two different models of organizational phenomena: the organizational phenomena that are putting managers and stakeholders in conditions of risk and the organizational phenomena that are putting them in condition of uncertainty. Using content analyze in this paper we survey the disclosure level of risk management information in the annual report of top Romanian listed companies.

    2015-11-01

    The federal and state governments are increasingly focusing on food labeling as a method to support good health. Many such laws are opposed by the food industry and may be challenged in court, raising the question of what is legally feasible. This article analyzes outstanding questions in First Amendment law related to commercial disclosure requirements and conducts legal analysis and policy evaluation for three current policies. These include the Food and Drug Administration's draft regulation requiring an added sugar disclosure on the Nutrition Facts panel, California's proposed sugar-sweetened beverage safety warning label bill, and Vermont's law requiring labels of genetically engineered food to disclose this information.

    Support from social networks is imperative to mental health recovery of persons with mental illness. However, disclosing mental illness may damage a person's participation in networks due to mental illness stigma, especially in Chinese immigrant communities where social networks (the guanxi network) have specific social-cultural significance. This study focused on mental illness disclosure in Chinese immigrant communities in New York City. Fifty-three Chinese psychiatric patients were recruited consecutively from 2 Chinese bilingual psychiatric inpatient units from 2006 to 2010. Two bilingual psychologists interviewed each participant once in a semistructured interview, including 6 questions on mental illness disclosure. Conventional content analysis was applied to conceptualize the phenomenon. Results showed that participants voluntarily disclosed to a circle of people composed primarily of family and relatives. The decisions and strategies to disclose depended on participants' consideration of 3 critical elements of social relationships. Ganqing, affection associated with relationship building, ultimately determined who had the privilege to know. Renqing, the moral code of reciprocal kindness, further influenced disclosure decisions and what participants anticipated as responses to disclosure. Lastly, concerns over preserving face (lian), a construct representing personal and familial dignity, oftentimes prohibited disclosure. Additionally, in this tight-knit network, involuntary disclosure could happen without participants' permission or knowledge. Participants commonly suffered from stigma after disclosure. However, half of our participants reported situations in which they experienced little discriminatory treatment, and some experienced support and care as a result of cultural dynamics. Recommendations for culturally sensitive practice to facilitate mental illness disclosure among Chinese immigrants were discussed. PsycINFO Database Record (c) 2013 APA, all

    Full Text Available Purpose: In this paper, we investigate the development, the current state, and the potential of business model disclosures to illustrate where, why and how organizations might want to disclose their business models to their stakeholders. The description of the business model may be relevant to stakeholders if it helps them to comprehend the company ‘story’ and increase understanding of other provided data (i.e. financial statements, risk exposure, sustainability of operations. It can also aid stakeholders in the assessment of sustainability of business models and the whole company. To realize these goals, business model descriptions should fulfil requirements of users suggested by various guidelines. Design/Methodology/Approach: First, we review and analyse literature on business model disclosure and some of its antecedents, including voluntary disclosure of intellectual capital. We also discuss business model reporting incentives from the viewpoint of shareholders, stakeholders and legitimacy theory. Second, we compare and discuss reporting guidelines on strategic reports, intellectual capital reports, and integrated reports through the lens of their requirements for business model disclosure and the consequences of their use for corporate report users. Third, we present, analyse and compare examples of good corporate practices in business model reporting. Findings: In the examined reporting guidelines, we find similarities, e.g. mostly structural but also qualitative attributes, in their presented information: materiality, completeness, connectivity, future orientation and conciseness. We also identify important differences between their frameworks concerning the target audience of the reports, business model definitions and business model disclosure requirements. Discontinuation of intellectual capital reporting conforming to DATI guidelines provides important warnings for the proponents of voluntary disclosure – especially for

    2008-02-01

    This study examines the role of spiritual disclosure within older adolescent-mother relationships. Spiritual disclosure is defined as mutual disclosure of personal religious and spiritual beliefs and practices. Three hundred 18- to 20-year-old college students and 130 of their mothers reported on spiritual disclosure in their relationships. According to both parties, greater spiritual disclosure was related to higher relationship satisfaction, greater use of collaborative conflict resolution strategies, less dysfunctional communication patterns, less verbal aggression, and increased general disclosure in mother-adolescent relationships beyond global religiousness and demographics. Spiritual disclosure also predicted unique variance in collaborative conflict resolution strategies beyond these factors and general disclosure. The findings underscore the value of attending to the interpersonal dimension of religion/spirituality. More specifically, the results suggest that spiritual disclosure is an indicator of relationship quality, one that is tied to better relationship functioning, and one that merits further attention in studies of family dynamics.

    1997-12-31

    For the first time, electricity consumers in the US are beginning to choose their generation providers. One of the opportunities created by the introduction of retail choice in electricity is the chance for customers to influence the mix of generating resources through their purchasing decisions. Some environmentally aware consumers will want {open_quotes}clean,{close_quotes} {open_quotes}green,{close_quotes} or renewable power. While some suppliers will attempt to differentiate themselves according to their environmental performance, such claims for green electricity can be particularly difficult to verify given the complexity of the interconnected electric system. Because electricity is delivered over an integrated transmission grid and kilowatt-hours at the point of retail sale are indistinguishable from each other; disclosure requires tracking protocols to attribute generation at power plants to sales at the customers` meters. Fortunately, it is possible to implement a workable disclosure system. Some states have already included disclosure requirements in their electric industry restructuring orders and legislation. In this paper, a set of design criteria for an environmental disclosure system are presented along with two methods for disclosure: the company approach and the product approach. In addition, the authors discuss of power pools, data availability issues, and propose a company-based disclosure system using a {open_quotes}wholesale sales first{close_quotes} approach to transaction accounting.

    Carbonaceous aerosol (TC) is a complex mixture of many organics (OC fraction) and elemental carbon (EC). EC is a product of anthropogenic activities, especially incomplete combustion of fossil fuels by transport, heating, power plants, wood and biomass burning and agriculture activities. EC could have larger health impact than other PM constituents (Cassee et al., 2013). Carbonaceous aerosols also play an important role in climate change (Boucher et al., 2013). Kosetice Observatory, operated by the Czech Hydrometeorological Institute has been carrying out long-term air quality monitoring at the background scale the Czech Republic since 1988. Regular EC-OC measurement has been implementing within EU-projects EUSAAR and ACTRIS since 2009. Sampling frequency is every 6th day in fraction PM2,5 on 2 quartz-fibre filters. Since October 2011 the sampling on filters has been implementing behind the denuder catching the organic vapor. Amount of OC on back quartz fiber filter represents positive artifact by measurement without denuder and negative artifact by measurements with denuder. The analytical method is thermal-optical analysis. The samples are analyzed in CHMI Central Laboratories in Prague-Libuš using EC-OC Sunset Lab Dual Analyzer. Charring correction is made by laser transmission monitoring. Slightly decreasing tendency of EC-OC was found in the period under review (2009-2014). The mean annual concentration of total carbon (TC) in PM2,5 was 3,73 µg.m-3. The figure for elemental carbon (0,5 µg.m-3) represents the mean annual ratio of 13% on TC. EC-OC concentrations follow an annual course that reflects their emission levels, i.e. with maximums in winter and minimums in summer. The seasonal variation of EC/TC ratio ranges between 9,6 (summer) - 14,2% (winter). Mean TC ratio on PM2,5 total mass in the period under review was 29%, the highest ratios reached 50%. EC participated on PM2,5 total mass by 3,5% in average. 3D trajectories were used for sector analysis of

    Full Text Available This paper investigates the relationship between annual report disclosure, market liquidity, and capital cost for firms registered on the Deutsche Börse. Disclosure is comprehensively measured using the innovative Artificial Intelligence Measurement of Disclosure (AIMD. Results show that annual report disclosure enhances market liquidity by changing investors’ expectations and inducing portfolio adjustments. Trading frictions are negatively associated with disclosure. The study provides evidence for a capital-costreduction effect of disclosure based on the analysis of investors’ return requirements and market values. Altogether, no evidence is found that the information processing at the German capital market is structurally different from other markets.

  14. Carbon Risk Analysis Of The South African Banks’ Lending To The JSE100 CDP Companies

    Alfred Bimha

    2015-11-01

    Full Text Available There is a pertinent concern over the continued lending to companies that are still pursuing projects that increase the amount of carbon emissions in the atmosphere. South Africa has most of its energy generation being done through coal thermal powered turbines. More so there are a number of new power stations being built in South Africa that are coal powered. Coal on the other hand is deemed as having the highest amount of carbon that contributes to the greenhouse effect which in turn affects the climate leading to climate change consequences. There is also a growing concern on the uptake of renewable energy initiatives by companies that are deemed carbon intensive. Banks are being castigated for not using their economic transformation role to champion the agenda of combating climate change caused by carbon emissions. In this study, the extent of lending in the short and long term to carbon intensive companies by South African banks is examined. Using a sample of the Johannesburg Stock Exchange top 100 companies that participate in Carbon Disclosure Project, an analysis is done through four carbon metrics –carbon intensity, carbon dependency, carbon exposure, carbon risk. The analysis used public information from the banks’ websites, South African Reserve Bank reports and other public databases that contain sustainability information of the JSE100 companies. The analysis was done by comparing the carbon metrics of the recognized seven (7 sectorial industry catergories (SIC on the JSE, mainly Energy & Materials, Industrials, Consumer Staples, Consumer Discretionary, Financials, IT & Telecoms and Health Care. The major finding of the research is that there is a high carbon risk in short term loans compared to long term loans across the JSE100 companies that are analysed. More so, the Energy & Materials sector seem to have the highest carbon risk compared to the other sectors.

    2007-09-01

    Reviews the book, Self-disclosure in psychotherapy by Barry A. Farber (see record 2006-11792-000). At one point or another, most therapists have wondered how much their patients are telling them and wrestled with how much they should reveal themselves to their patients. This book aims to provide an integrative and up-to-date review of the literature that has addressed these kinds of questions. By looking at patient, therapist, supervisee, and supervisor self-disclosure, Farber attempts to show both common and unique aspects of self-disclosure across the different parties involved in psychotherapy. Work from historical, clinical, research, and cultural perspectives comes together to provide readers with a multifaceted view of self-disclosure in psychotherapy. This book will be of interest to therapists, researchers, psychotherapy supervisors, and therapists-in-training. Farber's discussion of self-disclosure offers a nuanced perspective on the dilemmas involved in the psychotherapy process. By highlighting the features of self-disclosure across patients, therapists, supervisees, and supervisors, Farber enriches understanding of the phenomenon and encourages empathy for the perspectives of those in other psychotherapy roles. We believe that Farber has successfully synthesized work from various perspectives to create an illuminating review of self-disclosure in psychotherapy. The book condenses a broad range of literature into clearly organized and digestible chapters. The integration of research and theory with clinical vignettes, quotations from books and movies, and popular song lyrics make this work an unusually engaging and accessible read.

    As HIV is currently a chronic and manageable disease, an increasing amount of people living with HIV (PLHIV) are (again) active on the labour market. Since research on this topic is scarce, this study aimed to explore experiences of PLHIV in the workplace, especially concerning disclosure and adherence to antiretroviral therapy. A questionnaire was developed and validated in collaboration with Sensoa (Flemish expertise centre for sexual health) and participants were recruited using flyers and announcements on websites. A total of 54 PLHIV completed the questionnaire, among whom 50 (92·6%) males. Half of the participants did not disclose their HIV status in the workplace, mostly due to being afraid of social or professional consequences. Those who disclosed, reported no changes in the workplace or even reported receiving more empathy. A minority of participants have to take antiretroviral medication at work and they reported no particular problems related to medication intake. Despite improved solidarity and information campaigns, many PLHIV still do not disclose their HIV status in the workplace, most frequently due to fear for discrimination. More actions are warranted, as well as addressing possible self-stigma. Adherence to antiretroviral therapy in the workplace posed little or no problems.

    This research project is a collaboration between the Sinskey laboratory at MIT and the Worden laboratory at Michigan State University. The goal of the project is to produce Isobutanol (IBT), a branched-chain alcohol that can serve as a drop-in transportation fuel, through the engineered microbial biosynthesis of Carbon Dioxide, Hydrogen, and Oxygen using a novel bioreactor. This final technical report presents the findings of both the biological engineering work at MIT that extended the native branched-chain amino acid pathway of the wild type Ralstonia eutropha H16 to perform this biosynthesis, as well as the unique design, modeling, and construction of a bioreactor for incompatible gasses at Michigan State that enabled the operational testing of the complete system. This 105 page technical report summarizing the three years of research includes 72 figures and 11 tables of findings. Ralstonia eutropha (also known as Cupriavidus necator) is a Gram-negative, facultatively chemolithoautotrophic bacteria. It has been the principle organism used for the study of polyhydroxybutyrate (PHB) polymer biosynthesis. The wild-type Ralstonia eutropha H16 produces PHB as an intracellular carbon storage material while under nutrient stress in the presence of excess carbon. Under this stress, it can accumulate approximately 80 % of its cell dry weight (CDW) as this intracellular polymer. With the restoration of the required nutrients, the cells are then able to catabolize this polymer. If extracted from the cell, this PHB polymer can be processed into biodegradable and biocompatible plastics, however for this research, it is the efficient metabolic pathway channeling the captured carbon that is of interest. R. eutropha is further unique in that it contains two carbon-fixation Calvin–Benson–Bassham cycle operons, two oxygen-tolerant hydrogenases, and several formate dehydrogenases. It has also been much studied for its ability in the presence of oxygen, to fix carbon dioxide

    2016-06-01

    Self-disclosure of lived experiences with mental health challenges is a central method for challenging stigma and promoting empowerment. Individuals are encouraged to share their stories yet little is known about the process of self-disclosure in this context. This article presents the results of an investigation of the role of lived experience in professional training and work. A mixed methods design was used in a sequential exploratory manner. A purposive sample of 35 individuals participated in interviews and focus groups. Based on their reports and a literature review, an anonymous online survey (N = 117) was developed and distributed through consumer networks and the SAMHSA funded Consumer Technical Assistance Centers. The qualitative data was subjected to thematic analysis. The survey data were statistically analyzed for differences in levels of disclosure and factors regarding risks, benefits, and guidance regarding self-disclosure. Participants valued their lived experience as a resource through which they could assist others and service delivery. Lived experience was foundational to building relationships with individuals in recovery. Disclosure was dependent on social context and perceptions of safety. Individuals expressed concerns regarding exclusion and discrimination. Project participants maintained that their lived experience was their greatest strengths in helping others. At the same time, decisions about disclosure were made in complex social contexts featuring power differentials. Sharing lived experience is essential to peer-delivered services and further exploration is needed to support service development. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

  1. The Hestia Project: High Spatial Resolution Fossil Fuel Carbon Dioxide Emissions Quantification at Hourly Scale in Indianapolis, USA

    2009-12-01

    In order to advance the scientific understanding of carbon exchange with the land surface and contribute to sound, quantitatively-based U.S. climate change policy interests, quantification of greenhouse gases emissions drivers at fine spatial and temporal scales is essential. Quantification of fossil fuel CO2 emissions, the primary greenhouse gases, has become a key component to cost-effective CO2 emissions mitigation options and a carbon trading system. Called the ‘Hestia Project’, this pilot study generated CO2 emissions down to high spatial resolution and hourly scale for the greater Indianapolis region in the USA through the use of air quality and traffic monitoring data, remote sensing, GIS, and building energy modeling. The CO2 emissions were constructed from three data source categories: area, point, and mobile. For the area source emissions, we developed an energy consumption model using DOE/EIA survey data on building characteristics and energy consumption. With the Vulcan Project’s county-level CO2 emissions and simulated building energy consumption, we quantified the CO2 emissions for each individual building by allocating Vulcan emissions to roughly 50,000 structures in Indianapolis. The temporal pattern of CO2 emissions in each individual building was developed based on temporal patterns of energy consumption. The point sources emissions were derived from the EPA National Emissions Inventory data and effluent monitoring of electricity producing facilities. The mobile source CO2 emissions were estimated at the month/county scale using the Mobile6 combustion model and the National Mobile Inventory Model database. The month/county scale mobile source CO2 emissions were downscaled to the “native” spatial resolution of road segments every hour using a GIS road atlas and traffic monitoring data. The result is shown in Figure 1. The resulting urban-scale inventory can serve as a baseline of current CO2 emissions and should be of immediate use to

    Poor retention in care is common among HIV-positive adults in sub-Saharan Africa settings and remains a key barrier to HIV management. We quantify the associations of disclosure of HIV status and referral to disclosure counseling with successful retention in care using data from three Cameroon clinics participating in the Phase 1 International epidemiologic Databases to Evaluate AIDS Central Africa cohort. Of 1646 patients newly initiating antiretroviral therapy between January 2008 and January 2011, 43% were retained in care following treatment initiation. Self-disclosure of HIV status to at least one person prior to treatment initiation was associated with a minimal increase in the likelihood of being retained in care (risk ratio [RR] = 1.14; 95% confidence interval (CI): 0.94, 1.38). However, referral to disclosure counseling was associated with a moderate increase in retention (RR = 1.37; 95% CI: 1.21, 1.55) and was not significantly modified by prior disclosure status (p = .3). Our results suggest that while self-disclosure may not significantly improve retention among patients receiving care at these Cameroon sites, counseling services may play an important role regardless of prior disclosure status.

  13. Effects of therapist general self-disclosure and countertransference disclosure on ratings of the therapist and session.

    Myers, David; Hayes, Jeffrey A

    2006-01-01

    Therapist decisions about self-disclosure depend theoretically upon both content and context, such as the quality of the therapeutic relationship. In this analogue study, 224 undergraduates viewed 1 of 3 videos for which the working alliance was described as positive or negative and in which a therapist made general self-disclosures, countertransference disclosures, or no disclosures. Interaction effects indicated that participants rated sessions as deeper and the therapist as more expert when the therapist made general disclosures compared to no disclosures, but only when the alliance was positive. When the alliance was negative, participants perceived sessions as shallower and the therapist as less expert when the therapist made either general or countertransference disclosures compared to no disclosures.

  14. A collaborative project on the effects of coal quality on NO{sub x} emissions and carbon burnout in pulverised coal-fired utility boilers

    This paper describes a UK Department of Trade and Industry-supported collaborative project entitled `The Effects of Coal Quality on Emission of Oxides of Nitrogen (NO{sub x}) and Carbon Burnout in Pulverised Coal-fired Utility Boilers`. The project involved extensive collaboration between the UK power generators, boiler and burner manufacturers and research groups in both industry and academia, together with several of the world`s leading computational fluid dynamics (CFD) `software houses`. The prime objectives of the project were to assess the relationship between NO{sub x} emissions and carbon burnout and to develop and validate predictive tools for assessing coals. Experimental work was carried out on various laboratory-scale apparatus and on single burner test facilities ranging from 160 kW{sub th} to 40 MW{sub th} in size and measurements were obtained from full-scale 500 MW{sub e} utility boiler trials. This data and basic coal data were then used to develop mathematical models to predict full-scale boiler performance with respect to NO{sub x} emissions and carbon-in-ash. Results showed good correlations for NO{sub x} and carbon burnout when comparing data from full-scale and large-scale rig trials. Laboratory-scale tests were found to be useful but the influence of burner aerodynamics was more difficult to quantify. Modelling showed that predicted NO{sub x} emissions were encouragingly close to measured emissions but predicting carbon burnout was less successful. 24 refs., 4 figs., 6 tabs.

  3. From disclosure to transparency: the use of company payment data.

    Chimonas, Susan; Frosch, Zachary; Rothman, David J

    2011-01-10

    It has become standard practice in medical journals to require authors to disclose their relationships with industry. However, these requirements vary among journals and often lack specificity. As a result, disclosures may not consistently reveal author-industry ties. We examined the 2007 physician payment information from 5 orthopedic device companies to evaluate the current journal disclosure system. We compared company payment information for recipients of $1 million or more with disclosures in the recipients' journal articles. Payment data were obtained from Biomet, DePuy, Smith & Nephew, Stryker, and Zimmer. Disclosures were obtained in the acknowledgments section, conflict of interest statements, and financial disclosures of recipients' published articles. We also assessed variations in disclosure by authorship position, payment-article relatedness, and journal disclosure policies. Of the 41 individuals who received $1 million or more in 2007, 32 had published articles relating to orthopedics between January 1, 2008, and January 15, 2009. Disclosures of company payments varied considerably. Prominent authorship position and article-payment relatedness were associated with greater disclosure, although nondisclosure rates remained high (46% among first-, sole-, and senior-authored articles and 50% among articles directly or indirectly related to payments). The accuracy of disclosures did not vary with the strength of journals' disclosure policies. Current journal disclosure practices do not yield complete or consistent information regarding authors' industry ties. Medical journals, along with other medical institutions, should consider new strategies to facilitate accurate and complete transparency.

  7. RISK DISCLOSURE AGAINST ATTACK ON CRITICAL INFRASTRUCTURES

    Science.gov (United States)

    Yoshida, Mamoru; Kobayashi, Kiyoshi

    This paper analyzes the government's defensive and disclosure strategies to reduce the damage caused by terrorists that attack critical infrastructures using subjective game theory. The government recognizes a terrorist as a hidden opponent and the government's decision making about the policies against terror attacks depends on the belief about the existence of terrorist. In addition, it is not necessarily true that the government and the terrorist play the common game and make their decisions. Considering these points, the paper formulates the model in which the government and the terrorist formulate the subjective games respectively, and they induce the strategies using the equilibriums of their subjective games. The paper concluded that the government's disclosure about the implementation of the countermeasure, rather than the disclosure of warning level related with the belief about the existence of terrorist, brings about the higher increment of the subjective payoffs of the government.

  8. Determinants of The Islamic Social Reporting Disclosure

    Full Text Available The issue of corporate responsibility was a warm up for discussion. This study aimed to analyze the influence of company issuing sukuk, size, and profitability on the disclosure of Islamic Social Reporting. This study uses secondary data obtained through the site www.bapepam.go.id and www.idx.co.id by using purposive sampling. The results showed that only size that affect the disclosure of ISR, so the larger the total assets of the greater disclosure of Islamic Social Reporting. Sukuk issuance has no effect because the ownership structure of companies in Asia, including Indonesia tends to family ownership concentration. Profitability has no effect because the company has a perspective that is different to the Islamic Social Reporting.DOI: 10.15408/aiq.v9i1.3771

    2008-05-01

    Full Text Available The paper highlights theoretical aspects regarding corporate mandatory and voluntary disclosure. Since financial and business reporting are important information sources for different stakeholders, especially for publicly traded companies, the business reporting is increasingly oriented to the need of different users. In order to make rational investment decisions, users of corporate annual and interim reports require an extensive range of information. The increasing needs of the users persuade different international bodies and researchers to investigate the improvements that can be done in business reporting. The results of those studies usually were different reporting models. Because voluntary dimension of corporate disclosure involve the manifestation of free choice of the firm and its managers, we have considered as necessary to achieve a theoretical analysis of the main costs and profits of the voluntary disclosure policy.

    Earth system models demonstrate large uncertainty in projected changes in terrestrial carbon budgets. The lack of inclusion of adaptive responses of vegetation communities to the environment has been suggested to hamper the ability of modeled vegetation to adequately respond to environmental change. In this study, variation in functional responses of vegetation has been added to an earth system model (ESM) based on ecological principles. The restriction of viable mean trait values of vegetation communities by the environment, called 'habitat filtering', is an important ecological assembly rule and allows for determination of global scale trait-environment relationships. These relationships were applied to model trait variation for different plant functional types (PFTs). For three leaf traits (specific leaf area, maximum carboxylation rate at 25 °C, and maximum electron transport rate at 25 °C), relationships with multiple environmental drivers, such as precipitation, temperature, radiation, and CO2 , were determined for the PFTs within the Max Planck Institute ESM. With these relationships, spatiotemporal variation in these formerly fixed traits in PFTs was modeled in global change projections (IPCC RCP8.5 scenario). Inclusion of this environment-driven trait variation resulted in a strong reduction of the global carbon sink by at least 33% (2.1 Pg C yr(-1) ) from the 2nd quarter of the 21st century onward compared to the default model with fixed traits. In addition, the mid- and high latitudes became a stronger carbon sink and the tropics a stronger carbon source, caused by trait-induced differences in productivity and relative respirational costs. These results point toward a reduction of the global carbon sink when including a more realistic representation of functional vegetation responses, implying more carbon will stay airborne, which could fuel further climate change. © 2015 John Wiley & Sons Ltd.

    Jansen, Jos; Pollak, Andreas

    We study the strategic disclosure of demand information and product-market strategies of duopolists. In a setting where firms may fail to receive information, we show that firms selectively disclose information in equilibrium in order to influence their competitor's product-market strategy....... Subsequently, we analyze the firms' behavior in a laboratory experiment. We find that subjects often use selective disclosure strategies, and this finding appears to be robust to changes in the information structure, the mode of competition, and the degree of product-market conduct that is largely consistent...

    With the popularization of municipal sewage treatment facilities, the improvement of sewage treatment efficiency and the deepening degree of sewage treatment, the sludge production of sewage plant has been sharply increased. Carbon emission during the process of municipal sewage treatment and disposal has become one of the important sources of greenhouse gases that cause greenhouse effect. How to reduce carbon dioxide emissions during sewage treatment and disposal process is of great significance for reducing air pollution. Kitchen waste and excess sludge, as two important organic wastes, once uses anaerobic synergetic digestion technology in the treatment process can on the one hand, avoid instability of sludge individual anaerobic digestion, improve sludge degradation rate and marsh gas production rate, and on the other hand, help increase the reduction of carbon dioxide emissions to a great extent. The paper uses material balance method, analyzes and calculates the carbon dioxide emissions from kitchen waste and sludge disposed by the anaerobic synergetic digestion technology, compares the anaerobic synergetic digestion technology with traditional sludge sanitary landfill technology and works out the carbon dioxide emission reductions after synergetic digestion. It takes the kitchen waste and sludge synergetic digestion engineering project of Zhenjiang city in Jiangsu province as an example, makes material balance analysis using concrete data and works out the carbon dioxide daily emission reductions. The paper analyzes the actual situation of emission reduction by comparing the data, and found that the synergetic digestion of kitchen waste and sludge can effectively reduce the carbon dioxide emission, and the reduction is obvious especially compared with that of sludge sanitary landfill, which has a certain effect on whether to promote the use of the technology.

  16. Carbon dioxide and climate. [Appendix includes names and addresses of the Principal Investigators for the research projects funded in FY1991

    Energy Technology Data Exchange (ETDEWEB)

    1991-10-01

    Global climate change is a serious environmental concern, and the US has developed An Action Agenda'' to deal with it. At the heart of the US effort is the US Global Change Research Program (USGCRP), which has been developed by the Committee on Earth and Environmental Sciences (CEES) of the Federal Coordinating Council for Sciences, Engineering, and Technology (FCCSET). The USGCRP will provide the scientific basis for sound policy making on the climate-change issue. The DOE contribution to the USGCRP is the Carbon Dioxide Research Program, which now places particular emphasis on the rapid improvement of the capability to predict global and regional climate change. DOE's Carbon Dioxide Research Program has been addressing the carbon dioxide-climate change connection for more than twelve years and has provided a solid scientific foundation for the USGCRP. The expansion of the DOE effort reflects the increased attention that the Department has placed on the issue and is reflected in the National Energy Strategy (NES) that was released in 1991. This Program Summary describes projects funded by the Carbon Dioxide Research Program during FY 1991 and gives a brief overview of objectives, organization, and accomplishments. The Environmental Sciences Division of the Office of Health and Environmental Research, Office of Energy Research supports a Carbon Dioxide Research Program to determine the scientific linkage between the rise of greenhouse gases in the atmosphere, especially carbon dioxide, and climate and vegetation change. One facet is the Core CO{sub 2} Program, a pioneering program that DOE established more than 10 years ago to understand and predict the ways that fossil-fuel burning could affect atmospheric CO{sub 2} concentration, global climate, and the Earth's biosphere. Major research areas are: global carbon cycle; climate detection and models of climate change; vegetation research; resource analysis; and, information and integration.

    2016-09-01

    Full Text Available The first aim of the paper is to answer the question regarding the scope of the information on philanthrop- ic cooperation revealed by corporations and charitable organizations in a transition country. We explore the findings from the content analysis of disclosures of 41 corporations and 82 foundations. The results showed that the scope of disclosure on corporate and NGO collaborations is small on both sides. The second objective of the paper is to explore the reasons of the small scope of disclosure on corpo- rations’ and NGOs’ collaborations. In order to achieve the second aim, we extended our analysis through interviews with CSR managers and directors of foundations. Firstly, some managers adopt the stance that when there is no legal requirements or even voluntary guidelines (like GRI Guidelines, no further disclo- sure on collaboration is necessary. Moreover, the managers of corporations tend to follow the materiality rule in voluntary disclosure and reveal information only in projects with the biggest budgets and/or major social impact. NGOs do not see the benefits for them in publishing detailed information about their collaboration with companies.

    Uncovering the pathways to disclosures of child sexual abuse (CSA) and the factors influencing the willingness of victims to talk about the abuse is paramount to the development of powerful practice and policy initiatives. Framed as a long interview method utilizing a grounded theory approach to analyze data, the objective of the current study was to provide a preliminary mapping of the barriers to CSA disclosures through an ecological systemic lens, from a sample of 67 male and female CSA adult survivors, all of whom had recently received counselling services. The current project led to the identification of three broad categories of barriers that were each comprised of several subthemes, namely: Barriers from Within (internalized victim-blaming, mechanisms to protect oneself, and immature development at time of abuse); Barriers in Relation to Others (violence and dysfunction in the family, power dynamics, awareness of the impact of telling, and fragile social network); and Barriers in Relation to the Social World (labelling, taboo of sexuality, lack of services available, and culture or time period). This study points to the importance of using a broad ecological framework to understand the factors that inhibit disclosure of CSA, as barriers to disclosure do not constrain solely the victims. Results are discussed in light of their implications for research, prevention and intervention programs, and social policies and media campaigns, as the burden is on the larger community to create a climate of safety and transparency that makes the telling of CSA possible.

  20. Voluntary Disclosure in the Annual Reports of Financially Distressed Companies in Indonesia

    Directory of Open Access Journals (Sweden)

    Wijantini Wijantini

    2006-09-01

    Full Text Available This paper examines voluntary disclosure in the annual reports of financially distressed companies in Indonesia. The disclosure score range is between 3 percent and 49 percent with the mean and median score of 25 percent and 26 percent, respectively, at the onset of distress. The score is measured as the ratio of the total items disclosed to the maximum possible items score applicable to the firm. The most disclosed items are in the category of financial highlights and general corporate information whereas the three least disclosed items concern projections, liquidity, and research and development. Moreover, the results of this study reveal that the level of voluntary disclosure in the financially distressed firms is higher than that in non-financially distressed firms. There is no significant difference between the types of information disclosed by the 2  groups. The statistical tests are applied for various years. Consistent with findings in previous studies, the size of the firm appears to be a positive variable significantly affecting the disclosure level.

    Full Text Available This study aims to measure the degree of operational risk disclosure and examine its impact on operating cash flow of banks listed on the UAE Abu Dhabi Stock Exchange (ADX and Dubai Financial Market (DFM during the period 2003-2016. The authors conducted content analysis of the annual reports to measure the degree of operational risk disclosure. In addition, they used dynamic panel data regressions to analyze the impact of operational risk disclosure on the operating cash flow generated by the banks. The results show a low degree of operational risk disclosure for all UAE banks, both Islamic and conventional. In addition, the results show no association between the levels of disclosure of operational risk and cash flow for all banks, conventional and Islamic. Operational risk disclosure of Islamic banks has not been examined by any prior researchers. In addition, this paper examines the potential impact of operational risk disclosure on the operating cash flow generated by the banks.

  2. Assessing the National Bioengineered Food Disclosure Standard of 2016: Can Americans Access Electronic Disclosure Information?

    Full Text Available The debate as to whether to require mandatory labeling of genetically modified organism (GMO foods was partially settled on 29 July 2016, when President Obama signed the National Bioengineered Food Disclosure Standard into public law. In contrast to precipitating legislation passed by the State of Vermont that required disclosure of GMO ingredients on food shelves or food packages, the superseding National Standard allows firms to disclose bioengineered ingredients to consumers via symbols, electronic or digital links, or phone numbers, and further requires a study assessing the ability of consumers to access disclosure information by these means. This communication analyzes survey responses from 525 adults to investigate whether U.S. consumers are able to obtain information as per the disclosure methods allowed in the Federal legislation. The survey probes deeper to investigate consumer perceptions of genetically modified organisms and whether consumers would use the tools available to access disclosure about bioengineered ingredients. Findings from the survey show that 93.8% of respondents have the ability to access information via the disclosure methods permitted. Those in the lowest income group, and from the oldest age group are least likely to have such access. This provides the United State Department of Agriculture with information relevant to how they can implement the law and highlights particular demographic segments that may require additional attention to ensure the disclosed information is universally accessible.

  4. Japanese attitudes towards truth disclosure in cancer.

    Science.gov (United States)

    Tanida, N

    1994-03-01

    Despite the increasing concerns of truth disclosure, most cancer patients are not told the truth about their disease in Japan. The author has tried to provide some insight into this issue by evaluating results from questionnaires given to hospital patients, clients in a mass cancer survey, and doctors of a college hospital. Results showed that 72% of patients and 83% of clients wanted to be told the truth, but only 33% and 34% of them thought that the truth should be told to cancer patients. These attitudes of patients and clients regarding truth disclosure were more positive than those of the general public and health care workers in previous studies. At present, 13% of doctors inform cancer patients of their disease. These trends indicate that the Japanese attitude toward avoiding truth disclosure stems primarily from paternalism but is also influenced by social characteristics including insufficient understanding of this issue. Open discussion involving all factions of society is necessary to attain a better understanding of this issue and to promote eventual truth disclosure.

  9. Corporate Risk Disclosure and Corporate Governance

    Directory of Open Access Journals (Sweden)

    Kaouthar Lajili

    2009-12-01

    Full Text Available To date, research which integrates corporate governance and risk management has been limited. Yet, risk exposure and management are increasingly becoming the core function of modern business enterprises in various sectors and industries domestically and globally. Risk identification and management are crucial in any business strategy design and implementation. From the investors’ point of view, knowledge of the risk profile, risk appetite and risk management are key elements in making sound portfolio investment decisions. This paper examines the relationships between corporate governance mechanisms and risk disclosure behavior using a sample of Canadian publicly-traded companies (TSX 230. Results show that Canadian public companies are more likely to disclose risk management information over and above the mandatory risk disclosures, if they are larger in size and if their boards of directors have more independent members. Minority voting control ownership structures appear to negatively impact risk disclosure and CEO incentive compensation shows mixed results. The paper concludes that more research is needed to further assess the impact of various governance mechanisms on corporate risk management and disclosure behavior.

  3. Adult survivors of childhood cancers' identity disclosures in the workplace.

    Martinez, Larry R; Hebl, Michelle R

    2016-04-01

    Recent medical advances have resulted in unprecedented increases in the number and vitality of employed adult survivors. These survivors must make decisions about whether or not to disclose their identities to others. The purpose of this study was to examine the characteristics that are related to cancer survivorship disclosure in workplace settings (perceived organizational support, centrality of survivorship to one's self-concept, and the degree to which family and friends know about one's survivor status) and an important organizational consequence: intentions to leave one's job. A total of 151 adult survivors of childhood cancer completed an online survey. Extent of disclosure of one's identity as a cancer survivor was negatively associated with turnover intentions. Furthermore, organizational support, identity centrality, and disclosure outside of work were all related to disclosure in the workplace. Relative weight analysis revealed that disclosure outside of work was the most strongly related to disclosure at work. Finally, there were indirect relations such that disclosure mediated the relations among organizational support, identity centrality, and disclosure outside of work and turnover intentions. Survivors who were more open about their cancer survivor status at work had fewer intentions to leave their organizations. Importantly, although some antecedents to disclosure were personal characteristics, organizations can also encourage identity disclosure demonstrating that they are related to of work retention. While disclosure in the workplace is a complex decision to make, the relationship with work retention may reflect that disclosure is more likely to occur in an existing positive work environment or that disclosure itself may contribute to a positive work environment where employees tend to remain. The specific factors that trigger both disclosure and retention require further study although they are clearly related.

    2015-01-01

    Terrestrial carbon sequestration potential is widely considered as a realistic option for mitigating greenhouse gas emissions. However, this potential may be threatened by global changes including climate, land use, and management changes such as increased corn stover harvesting for rising production of cellulosic biofuel. Therefore, it is critical to investigate the dynamics of soil organic carbon (SOC) at regional or global scale. This study simulated the corn production and spatiotemporal changes of SOC in the U.S. Temperate Prairies, which covers over one-third of the U.S. corn acreage, using a biogeochemical model with multiple climate and land-use change projections. The corn production (either grain yield or stover biomass) could reach 88.7–104.7 TgC as of 2050, 70–101% increase when compared to the base year of 2010. A removal of 50% stover at the regional scale could be a reasonable cap in view of maintaining SOC content and soil fertility especially in the beginning years. The projected SOC dynamics indicated that the average carbon sequestration potential across the entire region may vary from 12.7 to 19.6 g C/m2/yr (i.e., 6.6–10.2 g TgC/yr). This study not only helps understand SOC dynamics but also provides decision support for sustainable biofuel development.

    2016-01-01

    Sulfate from seawater inhibits methane production in tidal wetlands, and by extension, salinity has been used as a general predictor of methane emissions. With the need to reduce methane flux uncertainties from tidal wetlands, eddy covariance (EC) techniques provide an integrated methane budget. The goals of this study were to: 1) establish methane emissions from natural, freshwater and brackish wetlands in Louisiana based on EC; and 2) determine if EC estimates conform to a methane-salinity relationship derived from temperate tidal wetlands with chamber sampling. Annual estimates of methane emissions from this study were 62.3 g CH4/m2/yr and 13.8 g CH4/m2/yr for the freshwater and brackish (8–10 psu) sites, respectively. If it is assumed that long-term, annual soil carbon sequestration rates of natural marshes are ~200 g C/m2/yr (7.3 tCO2e/ha/yr), healthy brackish marshes could be expected to act as a net radiative sink, equivalent to less than one-half the soil carbon accumulation rate after subtracting methane emissions (4.1 tCO2e/ha/yr). Carbon sequestration rates would need case-by-case assessment, but the EC methane emissions estimates in this study conformed well to an existing salinity-methane model that should serve as a basis for establishing emission factors for wetland carbon offset projects.

    Climate change is projected to push the limits of cropping systems and has the potential to disrupt the agricultural sector from local to global scales. This article introduces the Coordinated Climate-Crop Modeling Project (C3MP), an initiative of the Agricultural Model Intercomparison and Improvement Project (AgMIP) to engage a global network of crop modelers to explore the impacts of climate change via an investigation of crop responses to changes in carbon dioxide concentration ([CO2]), temperature, and water. As a demonstration of the C3MP protocols and enabled analyses, we apply the Decision Support System for Agrotechnology Transfer (DSSAT) CROPGRO-Peanut crop model for Henry County, Alabama, to evaluate responses to the range of plausible [CO2], temperature changes, and precipitation changes projected by climate models out to the end of the 21st century. These sensitivity tests are used to derive crop model emulators that estimate changes in mean yield and the coefficient of variation for seasonal yields across a broad range of climate conditions, reproducing mean yields from sensitivity test simulations with deviations of ca. 2% for rain-fed conditions. We apply these statistical emulators to investigate how peanuts respond to projections from various global climate models, time periods, and emissions scenarios, finding a robust projection of modest (20%) losses and larger uncertainty at the end of the century under the more severe representative concentration pathway (RCP8.5). This projection is not substantially altered by the selection of the AgMERRA global gridded climate dataset rather than the local historical observations, differences between the Third and Fifth Coupled Model Intercomparison Project (CMIP3 and CMIP5), or the use of the delta method of climate impacts analysis rather than the C3MP impacts response surface and emulator approach.

    This project is aimed at creation of the new industry of keeping water environments in good conditions in wide amphitrichous areas by establishing the technical systems for applying the phenomena in which microorganisms are massively immobilized on a carbon fiber bundle suspended in water to, e.g., purification of sewage systems, rivers and ponds, and providing sites for algae to grow, and by commercializing these systems. The following 3 themes have been established. The first theme is to develop the techniques for braiding/weaving carbon fibers. The second theme is to analyze characteristics of the immobilized microorganism groups. The third theme is to establish the principles of utilization. The FY 1997 R&D efforts were directed to production of a total of 57 types of braided/woven carbon fibers, development of sizing agents, and analysis of microorganism groups. In FY 1998, the carbon fibers treated with new sizing agents have been developed, and the braided/woven carbon fibers are being tested in water purification systems and algae sites. It is found that the microorganism groups exhibit synergistic effects between the pumping function and carbon/gel materials. The simulation models are being developed for system designs. The systems which apparently show the effects of this method have been classified by analyzing the field test results. (NEDO)

    Integrated assessment models (IAMs) simulate the interactions between human and natural systems at a global scale, representing a broad suite of phenomena across the global economy, energy system, land-use, and carbon cycling. Most proposed climate mitigation strategies rely on maintaining or enhancing the terrestrial carbon sink as a substantial contribution to restrain the concentration of greenhouse gases in the atmosphere, however most IAMs rely on simplified regional representations of terrestrial carbon dynamics. Our research aims to reduce uncertainties associated with forest modeling within integrated assessments, and to quantify the impacts of climate change on forest growth and productivity for integrated assessments of terrestrial carbon management. We developed the new Integrated Ecosystem Demography (iED) to increase terrestrial ecosystem process detail, resolution, and the utilization of remote sensing in integrated assessments. iED brings together state-of-the-art models of human society (GCAM), spatial land-use patterns (GLM) and terrestrial ecosystems (ED) in a fully coupled framework. The major innovative feature of iED is a consistent, process-based representation of ecosystem dynamics and carbon cycle throughout the human, terrestrial, land-use, and atmospheric components. One of the most challenging aspects of ecosystem modeling is to provide accurate initialization of land surface conditions to reflect non-equilibrium conditions, i.e., the actual successional state of the forest. As all plants in ED have an explicit height, it is one of the few ecosystem models that can be initialized directly with vegetation height data. Previous work has demonstrated that ecosystem model resolution and initialization data quality have a large effect on flux predictions at continental scales. Here we use a factorial modeling experiment to quantify the impacts of model integration, process detail, model resolution, and initialization data on projections of

    Distress disclosure has been linked with reduced psychological distress, increased wellbeing, and successful psychotherapeutic outcome. Because of the importance of distress disclosure, researchers have worked to develop and improve theoretical models of disclosure to facilitate counseling practices that reduce impediments to disclosure. Presently, we conducted a 2-part study to investigate distress disclosure's associations with attachment avoidance, gender, and alexithymia-3 constructs frequently linked with disclosure. In Part 1, we examined the extent to which attachment avoidance, alexithymia, and gender predicted general disclosure tendencies. In Part 2, we examined the extent to which attachment avoidance, alexithymia, and gender predicted event-specific disclosure. Participants were recruited from a crowdsourcing website (N = 178 in Part 1; N = 108 in Part 2). In Part 1, alexithymia partially mediated the association between attachment avoidance and disclosure tendencies, and the link between attachment avoidance and alexithymia was stronger for men than women. In Part 2, the association between distress intensity and event-specific disclosure was weaker for people with high levels of alexithymia. Implications for counseling theory and practice are discussed. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

  13. Self-disclosure on SNS: Do disclosure intimacy and narrativity influence interpersonal closeness and social attraction?

    On social media, users can easily share their feelings, thoughts, and experiences with the public, including people who they have no previous interaction with. Such information, though often embedded in a stream of others' news, may influence recipients' perception toward the discloser. We used a special design that enables a quasi-experience of SNS browsing, and examined if browsing other's posts in a news stream can create a feeling of familiarity and (even) closeness toward the discloser. In addition, disclosure messages can vary in the degree of intimacy (from superficial to intimate) and narrativity (from a random blather to a story-like narrative). The roles of disclosure intimacy and narrativity on perceived closeness and social attraction were examined by a 2 × 2 experimental design. By conducting one lab study and another online replication, we consistently found that disclosure frequency, when perceived as appropriate, predicted familiarity and closeness. The effects of disclosure intimacy and narrativity were not stable. Further exploratory analyses showed that the roles of disclosure intimacy on closeness and social attraction were constrained by the perceived appropriateness, and the effects of narrativity on closeness and social attraction were mediated by perceived entertainment value.

    2014-09-01

    In an experimental design, we tested whether written warnings can reduce the amount of identity information exposure online. A psychological attack on information privacy that has been shown to be effective in previous research was launched. This attack took advantage of the fact that people respond to certain types of requests in a relatively automatic, or mindless, fashion. The experiment manipulated the word that was used in the alert header: "warning", "caution", or "hazard". All warnings proved to be effective in reducing disclosure, but "hazard" proved to be most effective. Also warnings were more effective in reducing disclosure of driver's license numbers than email addresses. The discussion (a) provides tentative conclusions why these patterns were obtained, (b) suggests how to design warnings in cyber-environments, and (c) addresses future possibilities for research on this topic.

    Disclosure is often a challenge for individuals living with genital herpes. This study explores determinants of genital herpes disclosure with one's most recent sexual partner using an online questionnaire (n = 93). The majority of participants reported (80.4%) disclosure. Among non-disclosers, fear of negative partner reactions was the primary reason for non-disclosure. Age, relationship commitment, time in relationship, and expectations of partner's reaction were statistically significant predictors at the bivariate level. Reaction expectations and relationship commitment remained significant in the multivariate logistic regression model. Findings indicate that future disclosure research should focus on relationship context and managing negative expectations to increase disclosure. © The Author(s) 2015.

  18. Disclosures of Conflicts of Interest in Psychiatric Review Articles

    Kopelman, Andrew M.; Gorelick, David A.; Appelbaum, Paul S.

    2013-01-01

    To characterize disclosures of conflicts of interest in review articles in psychiatry, we identified 285 reviews from ten high-impact journals in psychiatry and two in general medicine. Disclosures were reliably coded as biotech/pharmaceutical/other material interests, nonprofit/government, communication companies, or other. Authors in both types of journals frequently reported industry ties. However, reviews in psychiatric journals were significantly less likely to include industry-related disclosures (32% of reviews; 18% of authors) compared with general medical journals (64% of articles; 40% of authors). The most common types of industry-related disclosures were for consulting, research support, and speaking fees. Disclosures appeared to be of limited utility in helping readers assess possible biases, because the nature and extent of the relationship being disclosed was often unclear. Efforts to screen out authors with significant financial relationships pertaining to the topic under review may be more effective than disclosure in protecting the integrity of the medical literature.

    2012-02-01

    Disclosure of personal information is believed to be more frequent in online compared to offline communication. However, this assumption is both theoretically and empirically contested. This systematic review examined existing research comparing online and offline self-disclosure to ascertain the evidence for current theories of online communication. Studies that compared online and offline disclosures in dyadic interactions were included for review. Contrary to expectations, disclosure was not consistently found to be greater in online contexts. Factors such as the relationship between the communicators, the specific mode of communication, and the context of the interaction appear to moderate the degree of disclosure. In relation to the theories of online communication, there is support for each theory. It is argued that the overlapping predictions of each theory and the current state of empirical research highlights a need for an overarching theory of communication that can account for disclosure in both online and offline interactions.

    2014-01-01

    The Great Mekong Subregion (GMS) contains one of the world's largest tropical forests and plays a vital role in sustainable development and provides a range of economic, social and environmental benefits, including essential ecosystem services such as climate change mitigation and adaptation. However, the forest in this Subregion is experiencing deforestation rates at high level due to human activities. The reduction of the forest area has negative influence to the environmental and natural resources issues, particularly, more severe disasters have occurred due to global warming and the release of the greenhouse gases. Therefore, in order to conduct forest management in the Subregion efficiently, the Forest Cover and Carbon Mapping in Greater Mekong Subregion and Malaysia project was initialized by the Asia-Pacific Network for Sustainable Forest Management and Rehabilitation (APFNet) with the collaboration of various research institutions including Institute of Forest Resource Information Technique (IFRIT), Chinese Academy of Forestry (CAF) and the countries in Sub region and Malaysia comprises of Cambodia, the People's Republic of China (Yunnan province and Guangxi province), Lao People's Democratic Republic, Malaysia, Myanmar, Thailand, and Viet Nam. The main target of the project is to apply the intensive use of recent satellite remote sensing technology, establishing regional forest cover maps, documenting forest change processes and estimating carbon storage in the GMS and Malaysia. In this paper, the authors present the implementation of the project in Thailand and demonstrate the result of forest cover mapping in the whole country in 2005 and 2010. The result of the project will contribute towards developing efficient tools to support decision makers to clearly understand the dynamic change of the forest cover which could benefit sustainable forest resource management in Thailand and the whole Subregion

    Development of a nanostructured synthetic carbons materials that have been synthesized by thermal-decomposition of aromatic rich polyether such as poly(ether ether ketone) (PEEK) is reported. These polymers based nanostructured carbons efficacious for gas adsorption and storage and have Brunauer-Emmett-Teller (BET) surface area of more than 3000 m2/g, and with average pore diameter of < 2nm. Surface-area, pore characteristics, and other critical variables for selecting porous materials of high gas adsorption capacities are presented. Analysis of the fragments evolved under various carbonization temperatures, and the correlation between the activation and carbonization temperatures provides a mechanistic perspective of the pore evolution during activation. Correlations between gas (N2 and H2) adsorption capacity and porous texture of the materials have been established. The materials possess excellent hydrogen storage properties, with hydrogen storage capacity up to 7.4 wt% (gravimetric) and ~ 45 g H2 L-1 (volumetric) at -196oC and 6.0 MPa.

    We take advantage of institutional changes and its characteristics in Japan to empirically examine mandatory business risk disclosure. We find that there is a negative impact on total risk from the introduction of mandatory business risk disclosure. This suggests that an increase in business risk disclosure reduces a firm's cost of capital, which is contrary to the results of previous research. However, we also find that there is a positive relationship across firms and years after inception ...

    I examine Health Maintenance Organizations' (HMOs) voluntary disclosure of product quality, which is not as complete as unraveling theories predict. After controlling for cost and demand factors, I find that HMOs use voluntary disclosure to differentiate from competitors, with lower disclosure rates in highly competitive markets. These findings are consistent with product differentiation, but challenge the intuition that competition should lead to more provision of quality information.

    Science.gov (United States)

    Harrison, Therese W

    2003-03-01

    Development of sexual identity in middle childhood and early adolescence is a natural process. However, it is more stressful for homosexual adolescents. Society continues to stigmatize and marginalize homosexuality. To avoid rejection and hostility, homosexual adolescents are pressured to hide their sexual identities. This fact compounds the anticipated normal developmental concerns of adolescence, and can create unique problems for the homosexual adolescents. Homosexuality can place them at risk for social stigmatization, isolation, depression, suicide, abuse, and rejection by their families and friends. During this exceptionally stressful time, both adolescent students and their families need anticipatory guidance and support. In providing anticipatory guidance, this article discusses critical roles played by professionals who work with adolescents in community or school settings. Included are insights into development of this normal variant of sexual attraction and orientation, risks that homosexual adolescent students may face as well as their disclosure concerns, and possible reactions families may have following disclosure. Supporting homosexual adolescents and their families is emphasized with regard to sensitively providing information, disclosure decisions, coping with stigmatization, and resiliency factors.

    2010-01-01

    Research suggests that many sexual assault survivors do not disclose their experience, which may increase associated distress. Pennebaker's emotional disclosure paradigm has been shown to ameliorate psychological and physical distress in individuals exposed to stressful events. The current study assessed the effectiveness of this paradigm with sexual assault survivors (N = 74). College women with a history of sexual assault wrote about their most severe victimization or about how they spend their time (control). Then 73 women (98.6%) completed a 1-month follow-up assessment. Results indicated that across writing sessions, the disclosure group reported greater reductions in negative mood immediately post-writing. However, both groups showed significant reductions in physical complaints, psychological distress, and traumatic stress symptoms at the 1-month follow-up, suggesting no added benefit to disclosure of a sexual assault using a brief written paradigm.

  16. Sustainability and Risk Disclosure: An Exploratory Study on Sustainability Reports

    Directory of Open Access Journals (Sweden)

    Elisa Truant

    2017-04-01

    Full Text Available Recent policy changes in sustainability reporting, such as the ones related to the new European Directive on non-financial disclosure (2014/95/EU, the standards issued by the American Sustainability Accounting Standard Board (SASB, the G4 guidelines issued by the Global Sustainability Standard Board (GSSB, and the framework of the International Integrated Reporting Council (IIRC stress the importance of extending the disclosure of ethical, social, and environmental risks within financial and social-environmental reporting. Institutional pressure has notably increased among organizations, in setting up risk management tools to understand sustainability risks within managerial and reporting practices. Given such institutional pressure, the corporate reaction in providing additional sustainability risk disclosure calls for attention and scrutiny. Therefore, this study aims at addressing such issues from an exploratory perspective. We based our analysis on a sample of large Italian organizations that issued sustainability disclosure in accordance with the Global Reporting Initiative (GRI, G4 guidelines, and we tested the relationship between their level of risk disclosure and other relevant variables. Consistently with the literature, we found that “experienced” sustainable reporters provide a significant volume of disclosure, and that disclosure quality on risk is positively influenced by their international presence and reporting experience. However, when accounting for specific risk-related areas of disclosure, only a few of them seem to adopt a managerial perspective linking strategy, risk metrics, and disclosure.

  18. Diminishing self-disclosure to maintain security in partners' care.

    Science.gov (United States)

    Lemay, Edward P; Melville, Michael C

    2014-01-01

    Six studies demonstrate that perceivers' desire to bond with targets motivates perceivers to misconstrue their own self-disclosure in ways that maintain perceivers' security in targets' care and commitment. Perceivers who strongly valued relationships with targets reported high levels of global self-disclosure, consistent with many findings suggesting salutary effects of disclosure. However, these same perceivers reported low self-disclosure of needs and desires in hypothetical (Study 1) and actual (Study 2) situations characterized by targets' unresponsive behavior. Similarly, in daily report (Study 3) and behavioral observation (Study 4) studies, perceivers who valued relationships with targets perceived high levels of self-disclosure when targets were responsive, but they perceived low self-disclosure when targets were unresponsive, and these perceptions seemed partly illusory. In turn, these perceptions of low self-disclosure in situations characterized by partners' unresponsive behavior predicted decreased perceptions of diagnosticity of targets' behavior (Studies 1-3) and buffered the negative affective and interpersonal effects of unresponsive behavior (Study 4). Experimental manipulations (Studies 5 and 6) demonstrated the motivational nature of perceived self-disclosure. Collectively, the results suggest that a desire to bond with targets motivates perceivers to downplay the diagnosticity of targets' unresponsive behavior through diminishing their self-disclosure, in turn preserving perceivers' trust in targets' care and commitment.

    1992-03-01

    This study was designed to assess whether children demonstrate covariant and equivalent forms of the reciprocity of self-disclosure, and if so, at what age. Twenty-one kindergarten, 23 second-grade, 24 fourth-grade, and 24 sixth-grade children were shown videotapes of three children (partners) who provided pre-established low-, medium-, and high-intimate disclosures. The subjects were required to send a message to the partners on topics varying in personal content. Fourth-grade children showed evidence of covariant reciprocity of self-disclosure by disclosing higher intimacy to high-intimate partners than to low-intimate partners. Sixth-grade children showed equivalent reciprocity of self-disclosure by providing a greater number of high- and medium-intimate disclosures to high- and medium-intimate partners, respectively, than to low-intimate partners. By contrast, neither form of reciprocity of self-disclosure was shown by kindergarten and second-grade children. Consistent with our expectations, girls provided a greater number of high-intimate disclosures than did boys in three of the four grades. The findings are discussed in terms of interplay between the development of the reciprocity of self-disclosure and the norm of the reciprocity of self-disclosure.

  3. Fuel choice, nuclear energy, climate and carbon

    Shpyth, A.

    2012-01-01

    For the second time since the start of commercial nuclear electricity generation, an accident has the world wondering if uranium will be among the future fuel choices in electricity production. Unfortunate when one considers the low-carbon footprint of this energy option. An accident involving a nuclear power plant, or more appropriately the perceived risks associated with an accident at a nuclear power plant, is but one of the issues that makes the impact assessment process related to nuclear energy projects challenging. Other aspects, including the time scales associated with their siting, licensing, operation and decommissioning, also contribute to the challenge. Strategic environmental assessments for future fuel choices in electricity generation, particularly ones that consider the use of life cycle assessment information, would allow for the effective evaluation of the issues identified above. But more importantly from an impact assessment perspective, provide for a comparative assertion for public disclosure on the environmental impacts of fuel choice. This would provide the public and government decision makers with a more complete view of the role nuclear energy may be able to play in mitigating the climate and carbon impacts of increased electricity production, and place issues of cost, complexity and scale in a more understandable context.

    Water resources management is an important public concern. In this study, we examined the extent of sorption/desorption of trace pollutants to soil black carbon (BC) in the water level fluctuation zone (WLFZ) of the middle route of the South to North Water Transfer Project in China. In addition, we investigated the main management measures affecting these processes during the project. The results showed that the pseudo second-order model adequately describes the sorption/desorption of phenanthrene on the soil BC in the WLFZ. Water level fluctuation may indirectly influenced BC sorption/desorption by altering water chemistry. Water level residence time had negative effects on BC sorption in short-term experiments (days to months), but the impact gradually diminished with increased residence time. The results suggested that long-term field monitoring of water chemistry is urgent. During the initial period of water transfer, delaying the water supplies as drinking water source or directly irrigating crops could mitigate the adverse impacts. Future research should focus on the water-soluble products of BC degradation. The findings of this study should be useful in improving sustainable management of water resources for water transfer projects. Copyright © 2018 Elsevier Ltd. All rights reserved.

  14. Supervisee self-disclosure: a clinical psychology perspective.

    Science.gov (United States)

    Spence, Nicola; Fox, John R E; Golding, Laura; Daiches, Anna

    2014-01-01

    Clinical supervision is a multi-functional intervention within numerous psychotherapeutic professions, including clinical psychology. It often relies on supervisees' verbal disclosures of pertinent information. There is limited research on supervisee self-disclosure in the UK, and none using clinical psychology populations. This study aimed to address the limitations in the evidence base. It used a constructivist grounded theory methodology to investigate qualified UK clinical psychologists' use of self-disclosure in supervision in order to develop a theoretical understanding of their self-disclosure processes. Ten clinical psychologists from various time points across the career span were recruited to the study. Four core conceptual categories were identified in the analysis as being integral to participants' decision-making processes: 'Setting the Scene', 'Supervisory Relationship', 'Using Self-disclosure' and 'Reviewing Outcome of Self-disclosure'. These four categories are comprised of a number of subcategories. The study's findings are compared with the current literature base, and it is argued that there are tensions with the scientist-practitioner model as it could be interpreted to encourage an expert stance, which may limit the self-disclosure of qualified supervisees. The implications of this perspective are discussed. Supervision is a key process in supporting qualified clinical psychologists and the use of disclosure appears to be important in facilitating useful supervision. It appears that clinical psychologists go through a number of complex processes in deciding whether to self disclose. Copyright © 2012 John Wiley & Sons, Ltd.

  9. Firm Traits and Web Based Disclosures in Top Nigerian Firms

    Directory of Open Access Journals (Sweden)

    Bello Ayuba

    2016-02-01

    Full Text Available The use of the internet as a medium of dissemination of information to stakeholders is increasingly gaining grounds. This study extends existing literature on web disclosures by investigating the characteristics that predict the extent of web-based disclosures. In this study, corporate websites of top Nigerian firms are used as sources of data, while a regression analysis is employed to examine the extent of prediction. Results indicate that the firm size and industry type are significant determinants of web disclosures. However, other firm traits such as ownership dispersion and financial performance do not significantly explain the extent of internet disclosures. The study recommends that a regulatory template for corporate web disclosures be put in place by government regardless of the size or industry classification of the firm. This is with a view to considerably reduce agency conflicts arising from information asymmetry in publicly listed firms in Nigeria.

  10. Culture and Sexual Self-Disclosure in Intimate Relationships

    Directory of Open Access Journals (Sweden)

    Nu Tang

    2013-12-01

    Full Text Available Sexual self-disclosure is one of the most intimate forms of self-disclosure. Yet, there is surprisingly little research on this topic compared to the voluminous research that exists on self-disclosure (in general. This is particularly surprising since sexual self-disclosure has been found to be correlated with sexual and marital satisfaction (Byers & Demmons, 2010. Conversations about sex have also been found to be critical in preventing HIV and other sexually transmitted infections, expressing sexual consent, and sexual desires and satisfaction (Faulkner & Lannutti, 2010. Nor have scholars investigated the impact of culture on people’s willingness to engage in sexual self-disclosure. In this paper, we will review current theorizing as to the extent to which culture and gender might be expected to influence young people’s willingness to sexually self-disclose, and suggest possible directions that future research might take.

  11. Self-Disclosure in Criminal Justice: What Form Does It Take and What Does It Achieve?

    Science.gov (United States)

    Phillips, Jake; Fowler, Andrew; Westaby, Chalen

    2018-01-01

    Self-disclosure, the act of therapists revealing something about themselves in the context of a professional relationship, has been linked with higher levels of effectiveness when used by correctional workers. However, it is poorly defined in both criminal justice policy and criminological research which has resulted in a lack of understanding about the potential risks and benefits to practice and practitioners. This article uses literature from other fields (namely, social work, counselling, and psychotherapy) to lay out what forms self-disclosure might take in the field of criminal justice. The article presents data that were generated as part of a larger project on emotional labour in probation practice in England. It analyses these data to argue that self-disclosure is used in two principle ways: to create and enhance a therapeutic relationship and in a more correctional way which is focused on criminogenic risk and need. We conclude by arguing that future research which seeks to identify a link between certain skills and effective outcomes needs to start with a much stronger definition of such skills as, otherwise, any effects are likely to be lost.

  12. Corrosion of carbon and low-alloy steel weldments in brines: A literature review: Salt Repository Project

    International Nuclear Information System (INIS)

    Reimus, P.W.

    1988-07-01

    The literature indicates that corrosion of carbon and low-alloy steel weldments in brines should not be a major concern if the weld is properly designed and fabricated. Seven characteristics of a weld can affect the corrosion performance of the weldment including composition of the weld metal (with respect to that of the parent metal); microstructure of the weld metal, heat-affected zone (HAZ), and parent metal; size and number of defects (cracks and pores) in the weld metal and HAZ (both internal and external); size, shape composition, location, and number of nonmetallic inclusions in the weld metal and HAZ; residual stress distribution in the weld; hydrogen content of the weld; and geometry of the weld at the outer surface. The effects of these characteristics on weldment corrosion are discussed in the report. 104 refs., 14 figs

    2014-09-01

    Full Text Available  This paper addresses the transparency and the quality of financial disclosures of listed entities in the case of an emerging economy (i.e. Romania, in order to shed some light on the particular local context of the country and its impact on accounting practices. We analyze the entire population of non-financial entities listed in the first tier of the Bucharest Stock Exchange for the 2012 financial year. We are limited in our research by the size of the sample, which depends, however, on the small size of the Romanian stock market. In order to compensate for the small size of the sample, we assess 50 items related to disclosure, synthesized in two scores, i.e. transparency and quality. Also, we identify some factors associated with disclosure by investigating the correlation with several firm-related factors. Our results reveal a medium level of transparency and quality of Romanian listed companies, with significant variations between firms and between the sub-scores. The most important factors correlated with disclosure are company size and the presence of institutional investors. The results confirm to some extent most of the basic assumptions of the agency theory and also prove the importance of a new variable for emerging econo-mies, specifically the presence of institutional investors *This work was cofinanced from the European Social Fund through Sectoral Operational Programme Human Resources Development 2007-2013, project number POSDRU/159/1.5/S./134197 a Performance and excellence in doctoral and postdoctoral research in Romanian economics science domaina.

  14. Final report of the project CARBOFOR. Carbon sequestration in the big forest ecosystems in France. Quantification, spatialization, vulnerability and impacts of different climatic and forestry scenario

    International Nuclear Information System (INIS)

    Loustau, D.

    2004-06-01

    The main outcomes of the project allowed to revise the carbon stock estimate of the national french forests, to clarify the interactions between climate and sylviculture according to the ecological profile of main species, to describe the changes in species area distribution for forest trees and pathogens. Different approaches for estimating the national carbon stock in forest biomass were investigated such as biomass equations and architectural models. Some conclusions in terms of adaptation scenario can be drawn. The global production potential of the french forest will be changed. This change is rapid and will occur a time interval shorter than average tree life duration. Species substitution and changing practices must be considered from now. The soil water holding capacity and the nutrient availability interact strongly with the climate effects and are therefore target factors for adapting forest stands to future changes. The dramatic change in the potential area distribution of most pathogens over France lead to recommend strong regulations for avoiding dissemination of fungal diseases and to anticipate the pathogen risks through species distribution.

Important biogeochemical material entering the oceans (including carbon) passes through this interface, but too little is known about the efficiency of this transport. Our goal in the NORDFLUX program is to improve quantitative understanding of the environmental feedbacks involved in these processes through an interdisciplinary study with innovative in situ observations. Completed work includes two in situ experiments in the Norwegian fiord (Porsangerfjorden) in the summers of 2014 and 2015. Experiments used research boat for collection of water samples and in situ bio-optical data, an autonomous glider, mooring with T S sensors, and a high frequency radar system. We have used these data to derive spatial maps of water temperature, salinity, surface currents, chlorophyll fluorescence, dissolved organic matter (DOM) fluorescence, and inherent optical properties (IOPs) of the water. The interpretation of these data in terms of suspended matter concentration and composition is possible by in situ 'calibrations' using water samples from discrete hydrographic stations. Total suspended matter (TSM), particulate carbon (POC and PIC), and dissolved organic carbon (DOC) concentrations together with measured water currents will allow us to estimate reservoirs and fluxes. Concentrations and fluxes will be related to physical conditions and meteorological data. An important aspect of this project is the work on regional ocean color algorithms. Global ocean color (OC) algorithms currently used by NASA do not perform sufficiently well in coastal Case 2 waters. Our data sets will allow us to derive such local algorithms. We will then use these algorithms for interpretation of OC data in terms of TSM concentrations and composition and DOC. After

  16. Secrets and disclosure in donor conception.

    2018-01-01

    This article considers the disclosure, sharing and exchange of information on being donor conceived within families, drawing on data from a study undertaken with donor-conceived adults registered with UK Donor Link (a voluntary DNA-linking register). This paper considers the narratives of how respondents found out they were donor-conceived and what events triggered disclosure of this information. This paper then goes on to examine the role secrecy played in their family life and uses the concept of 'display' to explore how secrecy affected their relationships with their immediate and extended family. Secrets are notoriously 'leaky' and we found complex patterns of knowing and uncertainty about whom in the family knew that the person was donor-conceived. We argue that what is kept secret and from whom provides insights into the multifaceted web of social relationships that can be created by donor-conception, and how knowledge can be managed and controlled in attempts to display and maintain family narratives of biogenetic connection. © 2017 Foundation for the Sociology of Health & Illness.

  17. Going Concern Disclosure for Local Governments

    2017-07-01

    Full Text Available Going concern opinions (GCOs indicate that auditors have significant doubt about an entity’s ability to continue operation one year after the financial statement date. This study addresses the following research questions: What are the factors that motivate auditors to issue GCOs to governmental entities? Does a governmental entity disclose going concern uncertainty in the footnotes or the MD&A section of annual financial reports (AFRs either the year before or the year when the entity receives a GCO? To what extent does the entity disclose the GCO factors used by auditors? We find that auditors most often cited two reasons, “Deficiency in Funds” and “Losses or Revenue Declines,” accounting for the majority of reasons given for a going concern opinion. Further, the disclosure is most likely to be in the notes to the AFRs. In addition, we find that going concern reporting varies by auditor type (state auditors vs. public accounting firms, government size, and government type. We also find some evidence that going concern disclosures improve after the enactment of GASB No. 56. The results of our study should be of interest to stakeholders’ interested in lead indicators of fiscal distress.

  18. Corporate Governance Effects on Social Responsibility Disclosures

    2017-06-01

    Full Text Available This study uses stakeholder theory to explore how corporate governance [CG] characteristics influence corporate social responsibility disclosure [CSRD] in the context of a global financial crisis [GFC]. Empirical data are drawn from Portugal, a country strongly affected by the GFC. Portuguese companies are characterized by high ownership concentration. The largest shareholder is often the CEO and Board Chair (a phenomenon known as CEO duality. We analyse the association between CSRD (measured by a 40-item disclosure index and CG variables (board size, CEO duality, board independence, ownership concentration and presence of an audit committee or CSR committee for 48 of the 51 listed companies in Portugal. The control variables are company size and industry type. We find that CSRD is affected positively by board size, CEO duality, company size and industry type. This accords with suggestions implicit in stakeholder theory that a larger board will represent a broader diversity of stakeholders and will promote better monitoring, more assertive stakeholder management, greater transparency, and increased levels of CSRD. Larger companies and companies close-to-consumers are associated with high levels of CSRD, ostensibly because they are more visible and subject to greater societal monitoring during a period of financial crisis. We reveal that in a country characterized by high ownership concentration, CEO duality has a positive effect on CSRD.

    2002-12-01

    The report is intended to be a guidance document for project developers, investors, lenders, and CDM host countries involved in wind power projects in the CDM. The report explores in particular those issues that are important in CDM project assessment and development - that is, baseline development, carbon financing, and environmental sustainability. It does not deal in detail with those issues that are routinely covered in a standard wind power project assessment. The report tests, compares, and recommends methodologies for and approaches to baseline development. To present the application and implications of the various methodologies and approaches in a concrete context, Africa's largest wind farm-namely the 60 MW wind farm located in Zafarana, Egypt- is examined as a hypothetical CDM wind power project The report shows that for the present case example there is a difference of about 25% between the lowest (0.5496 tCO2/MWh) and the highest emission rate (0.6868 tCO{sub 2}/MWh) estimated in accordance with these three standardized approaches to baseline development according to the Marrakesh Accord. This difference in emission factors comes about partly as a result of including hydroelectric power in the baseline scenario. Hydroelectric resources constitute around 21% of the generation capacity in Egypt, and, if excluding hydropower, the difference between the lowest and the highest baseline is reduced to 18%. Furthermore, since the two variations of the 'historical' baseline option examined result in the highest and the lowest baselines, by disregarding this baseline option altogether the difference between the lowest and the highest is reduced to 16%. The ES3-model, which the Systems Analysis Department at Risoe National Laboratory has developed, makes it possible for this report to explore the project-specific approach to baseline development in some detail. Based on quite disaggregated data on the Egyptian electricity system, including the wind

    The impact of the highly seasonal Antarctic primary production cycle on shelf benthic ecosystems remains poorly evaluated. Here we describe a times-series research project on the West Antarctic Peninsula (WAP) shelf designed to evaluate the seafloor deposition, and subsequent ecological and biogeochemical impacts, of the summer phytoplankton bloom along a transect crossing the Antarctic shelf near Anvers Island. During this project, entitled Food for Benthos on the Antarctic Continental Shelf (FOODBANCS), we deployed replicate sediment traps 150-170 m above the seafloor (total water-column depth of 590 m) on the central shelf from December 1999 to March 2001, recovering trap samples every 3-4 months. In addition, we used a seafloor time-lapse camera system, as well as video surveys conducted at 3-4 months intervals, to monitor the presence and accumulation of phytodetritus at the sediment-water interface. The fluxes of particulate organic carbon and chlorophyll- a into sediment traps (binned over 3-4 month intervals) showed patterns consistent with seasonal variability, with average summer fluxes during the first year exceeding winter fluxes by a factor of ˜2-3. However, inter-annual variability in summer fluxes was even greater than seasonal variability, with 4-10-fold differences in the flux of organic carbon and chlorophyll- a between the summer seasons of 1999-2000 and 2000-2001. Phytodetrital accumulation at the shelf floor also exhibited intense inter-annual variability, with no visible phytodetritus from essentially December 1999 to November 2000, followed by pulsed accumulation of 1-2 cm of phytodetritus over a ˜30,000 km 2 shelf area by March 2001. Comparisons with other studies suggest that the levels of inter-annual variability we observed are typical of the Antarctic shelf over decadal time scales. We conclude that fluxes of particulate organic carbon, chlorophyll- a and phytodetritus to WAP-shelf sediments vary intensely on seasonal to inter

  8. Catching flies with vinegar: a critique of the Centers for Medicare and Medicaid self-disclosure program.

    Science.gov (United States)

    Veilleux, Jean Wright

    2012-01-01

    This Article argues that the current approach of the Department of Health and Human Services and the Centers for Medicare and Medicaid Services (CMS) to enforcement of the Ethics in Patient Referrals Act (the "Stark Law") is unnecessarily punitive and discourages health-care providers from self-disclosing even very minor violations of the Stark Law. This Article suggests a number of specific changes to encourage provider self-disclosure and proposes that CMS create a demonstration project under the authority of the Patient Protection and Affordable Care Act to test the reforms. A demonstration project provides the perfect vehicle to prove that increased self-disclosure protocols for the Stark Law can decrease the government's costs of enforcement, improve program integrity, and encourage providers to deal responsibly with the inevitable minor lapses in compliance that arise in such an enormous government program as Medicare.

  9. Male self-disclosure of HIV infection to sex partners: a Hawaii-based sample.

    Science.gov (United States)

    Sullivan, Kathleen

    2009-01-01

    This exploratory study used a cross-sectional survey design with self-report to (a) describe serostatus disclosure to recent sex partners (SPs) among a multiethnic group of HIV-infected men from Hawaii, (b) explore factors influencing disclosure, and (c) examine relationships between disclosure and condom use. Respondents recalled their sexual experiences with up to three most recent SPs in the 3 months before survey administration. The men (N = 93) reported a disclosure rate of approximately 50% with 228 SPs. Disclosure was significantly influenced by SP serostatus, relationship status, self-efficacy for disclosure decision making, and cocaine use before sex. Disclosure was also significantly associated with condom use, highlighting the transmission risk reduction benefit of disclosure for these participants. HIV caregivers should routinely address disclosure to SPs and offer interventions to enhance condom use. Interventions for strengthening efficacy beliefs for disclosure decision making should be tailored to help men with multiple SPs and those with recent cocaine use.

    2005-04-01

    To understand how a norm of self-disclosure forms and is adhered to in a synchronous computer-mediated discussion, participants discussed the stigma of mental illness. The transcripts of the discussion were coded for the number of self-disclosures, the number of statements supportive of self-disclosure, and the number of statements supportive of non-self-disclosure. The results showed that the number of self-disclosing statements increased over time, although not in a linear fashion, as did the number of statements supportive of self-disclosure. However, the number of statements supportive of non-self-disclosures decreased over time. These results suggest that once a norm of self-disclosure forms, it is reinforced by statements supportive of self-disclosures but not of non-self-disclosures. The results are discussed in the context of self-disclosure reciprocity and the social identity model of deindividuation effects (SIDE).

  11. Three controversies over item disclosure in medical licensure examinations

    Directory of Open Access Journals (Sweden)

    2015-09-01

    Full Text Available In response to views on public's right to know, there is growing attention to item disclosure – release of items, answer keys, and performance data to the public – in medical licensure examinations and their potential impact on the test's ability to measure competence and select qualified candidates. Recent debates on this issue have sparked legislative action internationally, including South Korea, with prior discussions among North American countries dating over three decades. The purpose of this study is to identify and analyze three issues associated with item disclosure in medical licensure examinations – 1 fairness and validity, 2 impact on passing levels, and 3 utility of item disclosure – by synthesizing existing literature in relation to standards in testing. Historically, the controversy over item disclosure has centered on fairness and validity. Proponents of item disclosure stress test takers’ right to know, while opponents argue from a validity perspective. Item disclosure may bias item characteristics, such as difficulty and discrimination, and has consequences on setting passing levels. To date, there has been limited research on the utility of item disclosure for large scale testing. These issues requires ongoing and careful consideration.

    2014-05-01

    Writing about a personal stressful event has been found to have psychological and physical health benefits, especially when physiological response increases during writing. Response training was developed to amplify appropriate physiological reactivity in imagery exposure. The present study examined whether response training enhances the benefits of written emotional disclosure. Participants were assigned to either a written emotional disclosure condition (n=113) or a neutral writing condition (n=133). Participants in each condition wrote for 20 minutes on 3 occasions and received response training (n=79), stimulus training (n=84) or no training (n=83). Heart rate and skin conductance were recorded throughout a 10-minute baseline, 20-minute writing, and a 10-minute recovery period. Self-reported emotion was assessed in each session. One month after completing the sessions, participants completed follow-up assessments of psychological and physical health outcomes. Emotional disclosure elicited greater physiological reactivity and self-reported emotion than neutral writing. Response training amplified physiological reactivity to emotional disclosure. Greater heart rate during emotional disclosure was associated with the greatest reductions in event-related distress, depression, and physical illness symptoms at follow-up, especially among response trained participants. Results support an exposure explanation of emotional disclosure effects and are the first to demonstrate that response training facilitates emotional processing and may be a beneficial adjunct to written emotional disclosure.

  13. Physician assistants and the disclosure of medical error.

    Brock, Douglas M; Quella, Alicia; Lipira, Lauren; Lu, Dave W; Gallagher, Thomas H

    2014-06-01

    Evolving state law, professional societies, and national guidelines, including those of the American Medical Association and Joint Commission, recommend that patients receive transparent communication when a medical error occurs. Recommendations for error disclosure typically consist of an explanation that an error has occurred, delivery of an explicit apology, an explanation of the facts around the event, its medical ramifications and how care will be managed, and a description of how similar errors will be prevented in the future. Although error disclosure is widely endorsed in the medical and nursing literature, there is little discussion of the unique role that the physician assistant (PA) might play in these interactions. PAs are trained in the medical model and technically practice under the supervision of a physician. They are also commonly integrated into interprofessional health care teams in surgical and urgent care settings. PA practice is characterized by widely varying degrees of provider autonomy. How PAs should collaborate with physicians in sensitive error disclosure conversations with patients is unclear. With the number of practicing PAs growing rapidly in nearly all domains of medicine, their role in the error disclosure process warrants exploration. The authors call for educational societies and accrediting agencies to support policy to establish guidelines for PA disclosure of error. They encourage medical and PA researchers to explore and report best-practice disclosure roles for PAs. Finally, they recommend that PA educational programs implement trainings in disclosure skills, and hospitals and supervising physicians provide and support training for practicing PAs.

    Background Physicians can help guide teenagers in their emerging sexuality; however, teens rarely inform physicians about their sexual activity. Methods We audio-recorded annual visits between 365 teenagers and 49 physicians. sexual intercourse. Recordings were coded for teenage disclosures about previous sexual intercourse. We measured agreement between telephone survey responses and annual visit disclosures, and examined factors associated with agreement between the two. Results Fifty-six teenagers (15%) reported previous sexual intercourse in either the telephone survey or to their physician. Among those who reported sexual intercourse, 57% shared this information to both the telephone survey and their physician (κ = .72, confidence interval = 0.63–0.82). Conclusions Although a slight majority of teenagers disclosed their sexual activity to both the telephone survey and their doctor, a significant number disclosed to just one source. PMID:25857726

    Organizations from Spain, Belgium and the United Kingdom are collaborating in a field test of underground coal gasification which is being implemented in the north of Teruel Province (Spain). The test is first phase of a European development programme on in-situ coal gasification, being carried out with financial help from the Commission of the European Communities. This paper covers a forecast of the future energy demand for Europe, the potential of in-situ coal gasification, and a summary of the recent development of in-situ coal gasification. The circumstances which led to the formation of a European organisation (UEE) which will implement the project are described, and its objectives are presented. The geological characteristics of the proposed region are detailed, together with the test programme, and its successive phases in realising the principle parameters of the operations.

    2018-01-01

    Website of Non-governmental organization (NGO) is a focal medium of sharing information in response to transparency demands and addressing trust deficits between stakeholders. Many researchers have proposed accountability approaches to measure information sharing trends through websites. This article discusses a new index to measure online disclosure trends along with the theoretical properties of the index and a practical application of data from NGOs working in Pakistan. The websites have been coded in 2016. Results show that NGOs with branch offices have better disclosure scores than single-office NGOs, and international NGOs score better than local NGOs. NGOs that are more often the subject of newspaper reports have better disclosure trends.

    This article examines questions related to the "inescapable," the "inadvertent," and the "deliberate" personal disclosures by an analyst. Technical and personal considerations that influence the analyst's decision to disclose, as well as the inherent responsibilities and potential clinical consequences involved in self-disclosure, are explored, with particular attention to transference-countertransference dynamics, therapeutic goals, and the negotiation of resistance. The author describes her clinical work during a period of prolonged illness, with case vignettes that illustrate how-self-disclosure may be regarded as both an occasional authentic requirement and a regular intrinsic component of clinical technique.

    Full Text Available Voluntary disclosure meant giving information to public either about fi nancial or non-fi -nancial regarding the fi rm’s operations without any legal requirement (Fishman and Hagerty, 1997.Giving information about voluntary disclosure enables all the concerned parties obtaining more relevantinformation about the strategies and critical elements of the fi rms. In this study, we examinedthe impact of corporate governance and fi nancial distress condition on the level of voluntary informationdisclosure. This research used a sample of manufacture fi rms listed in Indonesian stockexchange. Based on data processing using sample above, we found that corporate governance andfi nancial distress could be associated with the voluntary disclosure level.

  20. The Impact Response of Carbon/Epoxy Laminates (Center Director's Discretionary Fund, Project No. 94-13)

    Nettles, A. T.; Hodge, A. J.

    1997-01-01

    Low velocity dropweight impact tests were conducted on carbon/epoxy laminates under various boundary conditions. The composite plates were 8-ply (+45,0,-45,90)s laminates supported in a clamped-clamped/free-free configuration with varying amounts of in-plane load, N(sub x), applied. Specimens were impacted at energies of 3.4, 4.5, and 6 Joules (2.5, 3.3, and 4.4 ft-lb). The amount of damage induced into the specimen was evaluated using instrumented impact techniques, x-ray inspection, and cross-sectional photomicroscopy. Some static identation tests were performed to examine if the impact events utilized in this study were of a quasi-static nature and also to gain insight into the shape of the deflected surface at various impact load combinations. Load-displacement curves from these tests were compared to those of the impact tests, as was damage determined from x-ray inspection. The finite element technique was used to model the impact event and determine the stress field within the laminae. Results showed that for a given impact energy level, more damage was induced into the specimen as the external in-plane load, N(sub x), was increased. The majority of damage observed consisted of back face splitting of the matrix parallel to the fibers in that ply, associated with delaminations emanating from these splits. The analysis showed qualitatively the results of impact conditions on maximum load of impact, maximum transverse deflection, and first failure mode and location.
