  1. Management strategies in anticipation of climatic change and the resulting impact on wetlands

    International Nuclear Information System (INIS)

    Two significant impacts of climate change could affect waterfowl. Climate changes that induce dryness and reduce surface water would have a detrimental effect on waterfowl production capabilities. Global warming could also increase sea levels and flood critical waterfowl overwintering habitat. Strategies undertaken by Ducks Unlimited, a waterfowl conservation organization, to respond to the threat posed by global warming to waterfowl are reviewed. Ducks Unlimited will continue to assist with wetland restoration and preservation throughout the Great Plains. Strategies to enhance retention include converting marginally arable land to permanent forage, forage backflooding, and encouragement of zero and minimum tillage operations. Improved efficiency of irrigation projects is important to foster water conservation. Widespread surface water drainage should be discouraged, by combinations of legislation and economic incentives. Ducks Unlimited is refocusing its activites on parts of Alberta, Saskatchewan and Manitoba that are likely to have relatively wetter conditions under climatic warming

  4. A change in strategy for a CERCLA Removal Action Demolition Project in progress results in overall project enhancements

    International Nuclear Information System (INIS)

    This paper discusses changes made in a demolition project at the Fernald Environmental Management Project (FEMP), a site on the National Priorities list (NPL), owned by the Department of Energy. The project, to demolish fourteen uranium ore silos and their structure, was based on a Removal Action Work Plan, submitted and approved by the United States Environmental Protection Agency (USEPA), that integrated Comprehensive Environmental Response Compensation and Liability Act (CERCLA) requirements to remove the source of contamination and threat to public health and the environment. After the demolition contractor defaulted at 30% complete, completion of the project by the USEPA deadline was threatened. The recovery plan included re-evaluation of project documents in addition to the schedule. It was determined that re-interpretation of the removal action criteria, including design and Removal Action Work Plan, would eliminate road-blocks, and optimize resources, resulting in project completion by the original deadline even after lost-time in mobilizing another contractor. This presentation will discuss the open-quotes lessons learnedclose quotes by the project team and illustrate how simplification of construction methods resulted in enhancements to the environmental controls, improved material handing, and created a safer work environment

  5. Innovative Urban Water Management as a Climate Change Adaptation Strategy: Results from the Implementation of the Project “Water Against Climate Change (WATACLIC”

    Directory of Open Access Journals (Sweden)

    Marco Pollastri

    2012-12-01

    Full Text Available The excessive use of water is damaging European groundwater and rivers: their environmental conditions are often below the “good status” that—according to Water Framework Directive 2000/60—should be reached by 2015. The already critical situation is tending to get worse because of climate change. Even in water rich countries, urban wastewater is still one of the main sources of water pollution. Currently, urban soil sealing and “conventional” rainwater management, which were planned to quickly move rainwater away from roofs and streets, are increasing the flood risk. “Green” technologies and approaches would permit a reduction in water abstraction and wastewater production while improving urban hydrological response to heavy rains. The Life+ WATACLIC project has been implemented to promote such sustainable technologies and approaches in Italy, however the results show huge difficulties: apparently water saving and sustainable urban water management have only low interest amongst the general public and even with public administrations and the relevant industrial sectors. In such a cultural and technical context, the project is bringing a new point of view to public debate. In the long term, the project will certainly have a positive impact, but most likely it will require more time than initially expected.

    Kolk, A.; Pinkse, J. [Business School, University of Amsterdam, Amsterdam (Netherlands)

    2004-06-01

    The issue of climate change has attracted increasing business attention in the past decade. Whereas companies initially aimed primarily at influencing the policy debate, corporate strategies increasingly include economic responses. Existing classifications for climate change strategies however still reflect the political, non-market components. Using empirical information from the largest multinational companies worldwide, this article examines current market responses, focusing on the drivers (threats and opportunities) and the actions being taken by companies to address climate change. It also develops a typology of climate strategies that addresses the market dimensions, covering both the aim (strategic intent) and the degree of cooperation (form of organisation). The aim turns out to be either innovation or compensation, while the organisational arrangements to reach this objective can be oriented at the company level (internal), at companies' own supply chain (vertical) or at cooperation with other companies (competitors or companies in other sectors - horizontal). The typology can assist managers in deciding about the strategic option(s) they want to choose regarding climate change, also based on the insights offered by the paper about the current state of activities of other companies worldwide.

  12. Urban trees and light-colored surfaces as a climate change strategy: Results from the US and potential in developing countries

    Energy Technology Data Exchange (ETDEWEB)

    Akbari, H.; Sathaye, J. [Lawrence Berkeley National Lab., CA (United States)

    1996-12-31

    This paper discusses the impact of two strategies in an urban environment for effecting substantial energy savings. They are the use of light colored materials on roofing and other flat surfaces, and the planting of additional trees. The lighter colored roofing materials will reflect more solar heat, resulting in lowered air conditioning costs. The additional trees will provide more shading, thereby increasing comfort, and will act as an aid in dropping the ambient temperature by means of evapotranspiration through the leaf systems. Both of these effects will reduce the direct energy inputs leading to air conditioning loads in an urban setting, and indirectly they will have an impact on urban smog though the lowered ambient temperature. The authors also discuss the applications of these ideas in developing countries, where often building energy costs can consume half of developed electrical capacity, and which tend to be in warmer climates. The density of many major urban areas in developing countries make the use of trees much harder to implement.

  15. A New Strategy for Mitigating Climate Change

    Energy Technology Data Exchange (ETDEWEB)

    Kaya, Y.; Akimoto, K./ Oda, J.

    2007-07-01

    This paper proposes a new strategy for mitigating climate change, both in short term and in long term. The basic character of the strategy is action oriented with multi-country collaboration, while the Framework Convention on Climate Change (FCCC) and Kyoto protocol is numerical target oriented within United Nation Framework. The introductory part of the paper briefly describes deficits of FCCC and Kyoto protocol and the needs of a different strategy for mitigating climate change. Then the short term strategy is focused on energy conservation and its effectiveness for mitigating climate change is illustrated by estimating the potential of reducing CO{sub 2} emission when intense collaboration is achieved for distributing main energy conservation measures in power generation and key industries among Asia Pacific Partnership countries. The long term strategy is developing novel types of renewables among countries. Geoheat and space solar power systems (SSPS) are candidates which may be developed among major developed countries. Necessity of international collaboration is stressed for R and D of these candidate renewables. (auth)

  16. Innovative Nuclear Fuels: Results and Strategy

    International Nuclear Information System (INIS)

    Materials discovery involves exploring and identifying existing (natural) materials with desirable properties and functionality. Materials design aims at creating new (artificial) materials with predefined properties and functionality. Nuclear fuels are often developed using both methods, with a certain advantage given to discovery. To facilitate the discovery and design of innovative nuclear fuels, multi-scale models and simulations are used to predict irradiation effects on the thermal conductivity, oxygen diffusivity, and thermal expansion of oxide fuels. The scientific method used in this approach covers a large spectrum of time and space scales, from electronic structure to atomistic levels, through meso-scale and all the way to continuum phenomena. The multi-scale approach is illustrated using results on UO2/PuO2 fuels with a focus on predictions of point defect concentrations, stoichiometry, and phase stability. The high performance computer simulations include coupled heat transport, diffusion, and thermal expansion, gas bubble formation and temperature evolution in a fuel element consisting of UO2 fuel and metallic cladding. Uncertainty evaluation reveals that ignoring the composition dependence of fuel properties in the simulations can lead to large errors (>100 k) in the calculations of the centerline temperature. The second part of the talk is dedicated to a discussion of an international strategy for developing advanced, innovative nuclear fuels. It starts with a brief review of the international status of nuclear fuels research, including results from American, European, and Japanese national laboratories and universities. In an effort to improve collaborative work, the status of thermo-chemical databases is used as an example of outstanding opportunities and exciting scientific programs that require better synchronization to advance the research and to avoid excessive redundancy. The presentation ends with a discussion of existing and emerging

  17. LINKING HUMAN RESOURCES STRATEGY WITH KNOWLEDGE MANAGEMENT STRATEGY TO DRIVE MEASURABLE RESULTS

    Directory of Open Access Journals (Sweden)

    Otilia‐Maria\tBORDEIANU

    2015-06-01

    Full Text Available Today the human resources are seen as a very valuable asset to achieve long-term performance. Today we understand that every employee is required to learn throughout life, so to acquire new knowledge, to process such knowledge and possibly disseminate expertise with other members of the organization. The theory on human resources in various organizations has changed over time; recommendations have become more numerous, but there is no consensus on the subject. In other words, the permanent change which defines the competitive environment of business remains a type of constant when analysing the efficiency of human resources within companies; inter-individual relations (formal and informal and the values to which each employee relates remains crucial for any theoretical construction in this area. Principles and strategies applied by organizations yesterday could prove their inefficiency today; human resource strategies in organizations today should include a separate subcomponent, we believe, i.e. knowledge management (KM strategy. This is because the competitive advantage obtained or maintained by the company depends today, in large proportion, on the type, quality and value of knowledge possessed by the organization. Therefore, organizational strategy and thus the strategy of acquisition, developing and rewarding of human resources (HR should take into account this reality from the global environment. Moreover, in the current knowledge-driven economy, organizations must know how to develop and implement knowledge-based strategies to drive measurable business results. The goal of this paper is to describe a potential relation between the overall company strategy, HR strategy and KM strategy.

  19. Canada's National Implementation Strategy on Climate Change

    International Nuclear Information System (INIS)

    This document describes the national implementation strategy which is a part of the coordinated national response to climate change. The approach was developed from the National Climate Change process, established by the federal, provincial and territorial ministers responsible for energy and the environment, based on an examination of the impacts, costs and benefits of implementing the Kyoto Protocol, as well as the options for addressing climate change. The Strategy involves (1) taking action to reduce risks and to improve our understanding of risks associated with climate change, (2) institution of a national framework that includes individual and joint action, while recognizing jurisdictional flexibility in responding to unique circumstances, (3) adopting a phased approach, (4) progressive action in response to changing domestic and international circumstances, (5) clear understanding of the necessary relationship between international and national strategies, (6) developing an understanding of the implications of emission reduction targets and major options, including cross-cutting policy approaches such as emissions trading and allocation of responsibility for reducing emissions. The Strategy uses a risk-management approach that attempts to limit the risks of climate change while maximizing opportunities for Canada to contribute to global and national solutions. This approach incorporates improving scientific and analytical understanding and co-ordinating national and international action and a phased approach to implementation. This policy document focuses on Phase One actions which consist of five connected themes, i. e. enhancing awareness and understanding, promoting technology development and innovation, governments leading by example, investing in knowledge and building the foundation, and encouraging action. Future phases will be linked to greater international certainty based on ratification of the Kyoto Protocol, the actions of our trading partners

  20. Postural strategy changes with fatigue of the lumbar extensor muscles.

    Wilson, Erin L; Madigan, Michael L; Davidson, Bradley S; Nussbaum, Maury A

    2006-04-01

    The purpose of this study was to investigate the effect of lumbar extensor fatigue on postural strategy in response to a balance perturbation. Anteriorly-directed force perturbations were applied to the upper back with a padded pendulum and attempted to challenge the postural control system without eliciting a stepping response. In three separate sessions, subjects were perturbed both before and after a fatiguing protocol that induced lumbar extensor fatigue to one of three different fatigue levels. Postural strategy was quantified using center of pressure position along with joint angles and joint torques for the ankle, knee, hip, and "low back" joints. Results showed both proactive and reactive changes in postural strategy. Proactive changes involved a slight anterior lean prior to the perturbation, and reactive changes were consistent with a shift toward more of a hip strategy with fatigue. In addition, results suggested that subjects classified as moving mostly at the hip prior to fatigue were more affected by fatigue compared to subjects classified as moving roughly equal amounts at the ankle and hip prior to fatigue. Increasing fatigue level exaggerated some, but not all, of the changes in postural strategy with fatigue. These findings illustrate that neuromuscular fatigue can influence postural strategy in response to a balance perturbation. PMID:16023345

  1. EU energy and climate change strategy

    International Nuclear Information System (INIS)

    This paper will summarise the European Strategy for Energy and Climate Change. In current international negotiations Europe has proposed a 20% reduction in GHG (greenhouse gases) in the developed countries by 2020 or 30% should there be an international agreement in the domain. However it is important to define measures to achieve the targets. One of the principal tools is to improve energy efficiency under the energy efficiency action plan, which will help to achieve a 20% energy saving by 2020. On the other hand, the amount of energy from renewable sources consumed in Europe will have to rise from its current level of 8.5%–20% by 2020. These are ambitious but achievable targets. Nonetheless, these can only be achieved through strong investment in areas of the knowledge triangle which strengthens research and innovation in the energy sector in Europe. The paper covers European Energy and Climate Change Policy, the European Strategic Energy Technology plan, the consequences of the Lisbon Treaty, European and national Road maps to a low carbon economy, the Energy Efficiency Plan for 2011 and finishes with a brief consideration of the EU’s energy infrastructure priorities. -- Highlights: ► This paper summarises the European Strategy for Energy and Climate Change. ► Reduction of GHG emissions by 30%-international agreement or −20% without agreement. ► Use of 20% of renewable energies by 2020. ► Increase of energy efficiency of 20% by 2020. ► Consolidating of the internal energy market.

  3. Climate change adaptation strategies and mitigation policies

    Science.gov (United States)

    García Fernández, Cristina

    2015-04-01

    The pace of climate change and the consequent warming of the Earth's surface is increasing vulnerability and decreasing adaptive capacity. Achieving a successful adaptation depends on the development of technology, institutional organization, financing availability and the exchange of information. Populations living in arid and semi-arid zones, low-lying coastal areas, land with water shortages or at risk of overflow or small islands are particularly vulnerable to climate change. Due to increasing population density in sensitive areas, some regions have become more vulnerable to events such as storms, floods and droughts, like the river basins and coastal plains. Human activities have fragmented and increased the vulnerability of ecosystems, which limit both, their natural adaptation and the effectiveness of the measures adopted. Adaptation means to carry out the necessary modifications for society to adapt to new climatic conditions in order to reduce their vulnerability to climate change. Adaptive capacity is the ability of a system to adjust to climate change (including climate variability and extremes) and to moderate potential damages, to take advantage of opportunities or face the consequences. Adaptation reduces the adverse impacts of climate change and enhance beneficial impacts, but will not prevent substantial cost that are produced by all damages. The performances require adaptation actions. These are defined and implemented at national, regional or local levels since many of the impacts and vulnerabilities depend on the particular economic, geographic and social circumstances of each country or region. We will present some adaptation strategies at national and local level and revise some cases of its implementation in several vulnerable areas. However, adaptation to climate change must be closely related to mitigation policies because the degree of change planned in different climatic variables is a function of the concentration levels that are achieved

  9. Adaptive strategies to climate change in Southern Malawi

    Science.gov (United States)

    Chidanti-Malunga, J.

    Climate change poses a big challenge to rural livelihoods in the Shire Valley area of Southern Malawi, where communities have depended almost entirely on rain-fed agriculture for generations. The Shire Valley area comprises of low-altitude dambo areas and uplands which have been the main agricultural areas. Since early to mid 1980s, the uplands have experienced prolonged droughts and poor rainfall distribution, while the dambos have experienced recurrent seasonal floods. This study assessed some of the adaptive strategies exercised by small-scale rural farmers in response to climate change in the Shire Valley. The methodology used in collecting information includes group discussions, household surveys in the area, secondary data, and field observations. The results show that small-scale rural farmers exercise a number of adaptive strategies in response to climate change. These adaptive strategies include: increased use of water resources for small-scale irrigation or wetland farming, mostly using simple delivery techniques; increased management of residual moisture; and increased alternative sources of income such as fishing and crop diversity. It was also observed that government promoted the use of portable motorized pumps for small-scale irrigation in order to mitigate the effects of climate change. However, these external interventions were not fully adopted; instead the farmers preferred local interventions which mostly had indigenous elements.

  11. Modelling rainfall erosion resulting from climate change

    Science.gov (United States)

    Kinnell, Peter

    2016-04-01

    It is well known that soil erosion leads to agricultural productivity decline and contributes to water quality decline. The current widely used models for determining soil erosion for management purposes in agriculture focus on long term (~20 years) average annual soil loss and are not well suited to determining variations that occur over short timespans and as a result of climate change. Soil loss resulting from rainfall erosion is directly dependent on the product of runoff and sediment concentration both of which are likely to be influenced by climate change. This presentation demonstrates the capacity of models like the USLE, USLE-M and WEPP to predict variations in runoff and erosion associated with rainfall events eroding bare fallow plots in the USA with a view to modelling rainfall erosion in areas subject to climate change.

  16. Change In Strategy - The Answer To Overcome Global Downturn

    Directory of Open Access Journals (Sweden)

    Siddhartha Ghosh

    Full Text Available In terms of overcoming the global downturn, innovative business strategy has three major dimensions namely, ‘Innovative Promotional Practices’, ‘Social and Organizational welfare’, and ‘Ethical behavior’. Fortunately most strategic dimensions in business and management are measurable so as to facilitate development ratings in order to compare and highlight the different levels of overcoming the global downturn.

    Arrays of eight, texture-defined rectangles were used as stimuli in a one-shot change blindness (CB) task where there was a 50% chance that one rectangle would change orientation between two successive presentations separated by an interval. CB was eliminated by cueing the target rectangle in the first stimulus, reduced by cueing in the interval and unaffected by cueing in the second presentation. This supports the idea that a representation was formed that persisted through the interval befo...

  2. Investigating afforestation and bioenergy CCS as climate change mitigation strategies

    International Nuclear Information System (INIS)

    The land-use sector can contribute to climate change mitigation not only by reducing greenhouse gas (GHG) emissions, but also by increasing carbon uptake from the atmosphere and thereby creating negative CO2 emissions. In this paper, we investigate two land-based climate change mitigation strategies for carbon removal: (1) afforestation and (2) bioenergy in combination with carbon capture and storage technology (bioenergy CCS). In our approach, a global tax on GHG emissions aimed at ambitious climate change mitigation incentivizes land-based mitigation by penalizing positive and rewarding negative CO2 emissions from the land-use system. We analyze afforestation and bioenergy CCS as standalone and combined mitigation strategies. We find that afforestation is a cost-efficient strategy for carbon removal at relatively low carbon prices, while bioenergy CCS becomes competitive only at higher prices. According to our results, cumulative carbon removal due to afforestation and bioenergy CCS is similar at the end of 21st century (600–700 GtCO2), while land-demand for afforestation is much higher compared to bioenergy CCS. In the combined setting, we identify competition for land, but the impact on the mitigation potential (1000 GtCO2) is partially alleviated by productivity increases in the agricultural sector. Moreover, our results indicate that early-century afforestation presumably will not negatively impact carbon removal due to bioenergy CCS in the second half of the 21st century. A sensitivity analysis shows that land-based mitigation is very sensitive to different levels of GHG taxes. Besides that, the mitigation potential of bioenergy CCS highly depends on the development of future bioenergy yields and the availability of geological carbon storage, while for afforestation projects the length of the crediting period is crucial.

    The paper discusses aspects of the implementation of the program for climatic change which has been come about as part of the U.N. Framework Convention on Climate Change. Initial effort has focused on providing strategic information and help to countries, on achieving offsets in greenhouse gas emissions by energy conservation or carbon sinking, and an emphasis on development of renewable energy supplies. The U.N. Development Agency has limited funding to help support startup on projects submitted. Specific examples are discussed in the areas of energy conservation and energy efficiency, adoption of renewable energy sources, and reducing the long-term costs of low greenhouse gas-emitting energy technologies.

    Full Text Available Business Mergers are the key for both big and small business corporations. This research paper determines the factors resulting into merger failures and considering “Strategic Change Management” as a solution to the query by doing comparison of corporate strategy and cultures of mergers between Europe and USA through statistics. Factors that lead to merger failures are misgauging strategic fit, cultural clash, communication gap, weak leadership and economic crisis by providing clear vision, putting together leadership team, focused management on success and winning the people’s commitment we can solve this query. The research has proved that cross-border mergers are highly influenced by cultural differences. The strategic change management led by new CEO can help in saving a new merger from a failure.

    Carlos Rubio-Bellido

    2015-03-01

    Full Text Available Historic city centres have a large amount of dwellings in Europe, which were built to provide a comfortable shelter with the absence of mechanical means. The knowledge of climate responsive design strategies can play a significant role in reducing the energy demand of extant buildings, paving the way for its sustainable development in the face of the rising threat to its occupants of climate change. The residential architecture, developed, in most cases, in dense urban centres, was built using both available materials and traditional and academic construction technologies. This paper thoroughly investigates the extant urban conglomerate in Cádiz and analyses, in a qualitative and quantitative manner, which bioclimatic design strategies were applied and the city’s adaptation for future climate scenarios. The results indicate that historic housing in Cádiz is creatively adapted to the local natural conditions by means of a combination of climate responsive strategies, and there is significant scope for improvement in the ongoing response to global warming.

  12. National strategy for climate change adaptation

    International Nuclear Information System (INIS)

    This book expresses the French State's view on the way to deal with the issue of climate change adaptation. After having recalled the ineluctability of some observed changes, the actors involved in this adaptation, and some guideline principles to implement adaptation, a first chapter describes the context: international mobilization, climate data evolution, definition of new criteria and critical thresholds, relationship between adaptation, alleviation and sustainable development, tensions between long and short terms. It discusses the objectives: public security and health, alleviation of inequalities with respect to risks, cost reduction, natural heritage preservation. Nine strategic axes are then identified: to develop knowledge, to strengthen the survey system, to inform, to educate and to make all actors aware, to promote a territory-based approach, to finance adaptation actions, to use regulatory and law instruments, to support voluntary approaches and the dialogue with private actors, to take the overseas peculiarity into account, and to contribute to international exchanges. The next chapters are respectively dealing with transverse approaches (water, risk prevention, health, and biodiversity), sector-based insights (agriculture, energy and industry, transports, building and housing, tourism, banks and insurance companies), medium-based approach (cities, littoral and seas, mountain, forest). The last part deals with the implementation issue

    The people who use Federal buildings — Federal employees, operations and maintenance staff, and the general public — can significantly impact a building’s environmental performance and the consumption of energy, water, and materials. Many factors influence building occupants’ use of resources (use behaviors) including work process requirements, ability to fulfill agency missions, new and possibly unfamiliar high-efficiency/high-performance building technologies; a lack of understanding, education, and training; inaccessible information or ineffective feedback mechanisms; and cultural norms and institutional rules and requirements, among others. While many strategies have been used to introduce new occupant use behaviors that promote sustainability and reduced resource consumption, few have been verified in the scientific literature or have properly documented case study results. This paper documents validated strategies that have been shown to encourage new use behaviors that can result in significant, persistent, and measureable reductions in resource consumption. From the peer-reviewed literature, the paper identifies relevant strategies for Federal facilities and commercial buildings that focus on the individual, groups of individuals (e.g., work groups), and institutions — their policies, requirements, and culture. The paper documents methods with evidence of success in changing use behaviors and enabling occupants to effectively interact with new technologies/designs. It also provides a case study of the strategies used at a Federal facility — Fort Carson, Colorado. The paper documents gaps in the current literature and approaches, and provides topics for future research.

  5. The oil industry and climate change. Strategies and ethical dilemmas

    International Nuclear Information System (INIS)

    This paper explores the different climate change strategies chosen by three major multinational oil corporations: ExxonMobil, TotalFinaElf and BP Amoco. They are referred to, as the 'fight against emission constraints,' 'wait and see', and 'proactive' strategies, respectively. The justifications given to support these strategies are identified. They cover the business, scientific, political, economic, technological and social dimensions. In a business ethics framework, the issue of climate change brings forth an ethical dilemma for the oil industry, in the form of a tension between profits and CO2 emissions. The strategies are analysed as three attitudes towards this dilemma: (1) placing priority on the business consequences while weakening the perception that anthropogenic greenhouse gas emissions are causing climate change; (2) avoiding responsibility; and (3) placing priority on the need for a modification of the business process while limiting the negative effect in terms of business consequences. In conclusion, we propose that beyond the ethical issues proper to climate change itself, additional ethical issues are raised if society at large is instrumentalised by an industry in its search for profit. Publicly gauging and valorising the ethical commitment of a corporation appear as ways of inducing more collaborative and proactive attitudes by business actors

    A one-third octave spectral analysis was performed on two sentences spoken by 5 patients with laryngeal cancer, 5 with head/neck cancer not involving the vocal cords, and 12 normal subjects. Recordings were made prior to and at weekly intervals during radiotherapy as well as at periodic intervals post-treatment. Patients with laryngeal cancer exhibited lower spectral levels than normal throughout radiotherapy as well as several months post-treatment. By one year after treatment, the spectral levels of these patients were largely in the normal range. Patients with head/neck cancer not involving the vocal cords exhibited greater than normal sound pressure levels throughout most of the spectrum. These levels remained high even at one month post-treatment. Irradiation of normal vocal cord tissue also seems to result in higher spectral levels.

    2009-04-01

    Artificial Neural Networks (ANNs) are a mathematical model of the main known characteristics of biological brian dynamics. ANNs inspired in biological reality have been useful to design machines that show some human-like behaviours. Based on them, many experimentes have been succesfully developed emulating several biologial neurons characteristics, as learning how to solve a given problem. Sometimes, experimentes on ANNs feedback to biology and allow advances in understanding the biological brian behaviour, allowing the proposal of new therapies for medical problems involving neurons performing. Following this line, the author present results on artificial learning on ANN, and interpret them aiming to reinforce one of this two didactic estrategies to learn how to solve a given difficult task: a) To train with clear, simple, representative examples and feel confidence in brian generalization capabilities to achieve succes in more complicated cases. b) To teach with a set of difficult cases of the problem feeling confidence that the brian will efficiently solve the rest of cases if it is able to solve the difficult ones. Results may contribute in the discussion of how to orientate the design innovative succesful teaching strategies in the education field.

    Under the influence of managed care and diminished funding, the mental health field is undergoing a major transformation. Existing mental health programs, departments, and agencies are downsizing and restructuring to develop new types of service delivery systems. Organizations must change to survive; yet necessary and adaptive change may be resisted in numerous ways by providers whose reactions and behaviors may reduce the viability of their own programs and agencies. This paper explores various characteristics and reactions of mental health care professionals as they face great stress, professional devaluation, and necessary organizational change and restructuring. Adaptive and maladaptive patterns in response to potential organizational change are explored. The role of the leader in guiding and implementing programmatic changes and in dealing with denial and resistance is highlighted. Strategies to enhance the prospects for adaptive organizational change are offered. PMID:9919625

  15. Radon mapping in Austria. New strategies and first results

    International Nuclear Information System (INIS)

    In Austria the set up of radon maps is required already since 1992 in the recommendation of the radiation protection commission and stated in the radiation protection law since 2004. In the framework of the Austrian National Radon Project (OENRAP) indoor radon measurements were carried out in about 9000 dwellings from 1992 to 2002, a radon potential was calculated for all municipalities and displayed in a radon potential map. This map is basis for decisions e.g. for preventive measures. According to the new European basic safety standards (EU-BSS) member states shall identify ''radon areas'', relevant e.g. for mandatory radon measurements at work places. The identification of such areas will impact several (legal) decisions and future measures. In course of the implementation of the EU-BSS the radon map of Austria should be improved and optimized for its purpose. As a first step indoor radon measurements were carried out in dwellings in municipalities detected to be ''outliers'' compared to neighboring municipalities. In addition a new indoor radon survey was designed and started, funded by the BMLFUW, with radon measurements in dwellings of members of the voluntary fire brigades, selected by defined criteria. As a pilot study measurements in about 6500 dwellings were carried out in Upper Austria from June 2014 to February 2015. Based on the results of the pilot study and an international radon mapping workshop held in Vienna in January 2015 possible methods for radon mapping in Austria will be tested and discussed. In this contribution the strategies, methods, first results and findings on the way to a new Austrian radon map will be presented.

    Full Text Available Abstract Background Demand for rehabilitation services is expected to increase due to factors such as an aging population, workforce pressures, rise in chronic and complex multi-system disorders, advances in technology, and changes in interprofessional health service delivery models. However, health human resource (HHR strategies for Canadian rehabilitation professionals are lagging behind other professional groups such as physicians and nurses. The objectives of this study were: 1 to identify recruitment and retention strategies of rehabilitation professionals including occupational therapists, physical therapists and speech language pathologists from the literature; and 2 to investigate both the importance and feasibility of the identified strategies using expert panels amongst HHR and education experts. Methods A review of the literature was conducted to identify recruitment and retention strategies for rehabilitation professionals. Two expert panels, one on Recruitment and Retention and the other on Education were convened to determine the importance and feasibility of the identified strategies. A modified-delphi process was used to gain consensus and to rate the identified strategies along these two dimensions. Results A total of 34 strategies were identified by the Recruitment and Retention and Education expert panels as being important and feasible for the development of a HHR plan for recruitment and retention of rehabilitation professionals. Seven were categorized under the Quality of Worklife and Work Environment theme, another seven in Financial Incentives and Marketing, two in Workload and Skill Mix, thirteen in Professional Development and five in Education and Training. Conclusion Based on the results from the expert panels, the three major areas of focus for HHR planning in the rehabilitation sector should include strategies addressing Quality of Worklife and Work Environment, Financial Incentives and Marketing and Professional

  18. Different hunting strategies of generalist predators result in functional differences.

    2016-08-01

    The morphological, physiological, and behavioural traits of organisms are often used as surrogates for actual ecological functions. However, differences in these traits do not necessarily lead to functional differences and/or can be context-dependent. Therefore, it is necessary to explicitly test whether the surrogates have general ecological relevance. To investigate the relationship between the hunting strategies of predators (i.e., how, where, and when they hunt) and their function, we used euryphagous spiders as a model group. We used published data on the diet composition of 76 spider species based on natural prey and laboratory prey acceptance experiments. We computed differences in the position and width of trophic niches among pairs of sympatrically occurring species. Pairs were made at different classification levels, ranked according to the dissimilarity in their hunting strategies: congeners, confamiliars (as phylogenetic proxies for similarity in hunting strategy), species from the same main class of hunting strategy, from the same supra-class, and from different supra-classes. As for niche position computed from the natural prey analyses, species from the same class differed less than species from different classes. A similar pattern was obtained from the laboratory studies, but the congeners differed less than the species from the same classes. Niche widths were most similar among congeners and dissimilar among species from different supra-classes. Functional differences among euryphagous spiders increased continuously with increasing difference in their hunting strategy. The relative frequency of hunting strategies within spider assemblages can, therefore, influence the food webs through hunting strategy-specific predator-prey interactions. PMID:27098662

    2014-12-01

    Full Text Available This paper aims to reflect the importance of a knowledge management strategy for organisations facing organisational change, as response to crisis. As resource for development, for sure knowledge becomes an inexhaustible power. It is also one of the most important forms of capital - the foundation for innovation and also the drivers that lead to growth and expansion. An organization cannot compete with others in this ever-changing environment without proper knowledge and lack of capacity for renewal. Many managers would like to have a strategic approach in preparing the organisation to avoid crisis. There is a lack of strategic information management and the effect is the degradation of information resources and failure in strengthening employee’s potential. It is vital for the companies to develop a dynamic knowledge management strategy to be integrated into the organization, enhancing the performance of the system and processes. However, organizations need to see knowledge management as a strategy, because knowledge is the key to making the right decisions in guiding the organization. One of the key benefits of approaching knowledge management strategy within organisations is its positive impact on organisational performance, ensuring not only the survival during crisis but even providing a competitive advantage.

  1. 'Reliability methods for passive systems' (RMPS) study - Strategy and results

    International Nuclear Information System (INIS)

    The RMPS (Reliability Methods for Passive Systems) is a research programme sponsored by EU within the 5. European Framework Programme. Main goal of the activity, begun in the first half of 2001, is the identification of a suitable methodology capable to evaluate both qualitatively and quantitatively the reliability of passive systems. The research development foresees the application of such a methodology to study cases, e.g. passive systems of industrial interest. The working team is leaded by CEA and groups research centres (GRS, JRC, ENEA), universities (CIRTEN consortium) and industries (Technicatome). The approach moves from a previous study performed by ENEA and some CIRTEN partners. The strategy is based on the identification of all possible ways of departure of the system from the nominal behaviour, defined at the design stage. The passive system can fail its mission not only due to classical mechanical failures, but also because of physical failures, usually related to thermalhydraulic features. Moreover, the failure state of the passive system has to be defined, e.g. connected to physical parameters as natural circulation flow rate or heat transfer rate. The paper reports a preliminary road-map proposed for the development of the RMPS method, with a brief description for each step. Then a sensitivity analysis on the results of the previous study has been performed, showing the most important parameters affecting the behavior of the passive safety system selected as a case study. The analysis revealed also a singular occurrence in the calculations and some considerations have been drew. Finally, a useful basis for a thorough Expert Judgement process, to be carried out on the identification of the characteristic parameters for the passive safety system, has been set up. Justifications for the selection of the main parameters affecting the system behavior, hence its reliability, for their ranges of variation and their probability of occurrence have been

    International Nuclear Information System (INIS)

    Companies face much uncertainty about the competitive effects of the recently adopted Kyoto Protocol on global climate change and the current and future regulations that may emerge from it. Companies have considerable discretion to explore different market strategies to address global warming and reduce greenhouse gas emissions. This article examines these strategic options by reviewing the market-oriented actions that are currently being taken by 136 large companies that are part of the Global 500. There are six different market strategies that companies use to address climate change and that consist of different combinations of the market components available to managers. Managers can choose between more emphasis on improvements in their business activities through innovation or employ compensatory approaches such as emissions trading. They can either act by themselves or work with other companies, NGOs, or (local) governments

  4. Developing Canada's climate change strategy : electricity sector table

    International Nuclear Information System (INIS)

    Canada's climate change strategy has been the focus of extensive consultation processes whose objective is to provide recommendations to federal and provincial ministers by the end of 1999. They are also designed to study the impact, the cost and the benefits of implementation of the Kyoto Protocol and to develop immediate actions to provide early reductions in CO2 emissions. The development of long-term actions that will result in sustained greenhouse gas (GHG) reductions is also on the agenda. The role of the Electricity Sector Table is to determine the contribution of GHG emissions by power generation, transmission and distribution elements as well as by electricity and cogeneration industries. The contribution of GHG emissions by renewable energy is also being studied. One of the recommended early actions is that the federal government should include solution gas as a qualifying fuel in Class 43.1 of the Income Tax Act to provide incentives to produce electricity from waste solution gas in fossil fuel production. Natural Resources Canada predicts that GHG emissions from the electricity sector will have increased from 94 MT in 1990 to 146 MT by 2020. The current sources of power generation in Canada are as follows: hydroelectric (65 per cent), nuclear (15 per cent), coal (15 per cent), and other (5 per cent)

  9. Adaptation or Manipulation? Unpacking Climate Change Response Strategies

    Directory of Open Access Journals (Sweden)

    Timothy F. Smith

    2012-09-01

    Full Text Available Adaptation is a key feature of sustainable social–ecological systems. As societies traverse various temporal and spatial scales, they are exposed to differing contexts and precursors for adaptation. A cursory view of the response to these differing contexts and precursors suggests the particular ability of persistent societies to adapt to changing circumstances. Yet a closer examination into the meaning of adaptation and its relationship to concepts of resilience, vulnerability, and sustainability illustrates that, in many cases, societies actually manipulate their social–ecological contexts rather than adapt to them. It could be argued that manipulative behaviors are a subset of a broader suite of adaptive behaviors; however, this paper suggests that manipulative behaviors have fundamentally different intentions and outcomes. Specifically, adaptive behaviors are respectful of the intrinsic integrity of social–ecological systems and change is directed toward internal or self-regulating modification. By way of contrast, manipulative behaviors tend to disregard the integrity of social–ecological systems and focus on external change or manipulating the broader system with the aim of making self-regulation unnecessary. It is argued that adaptive behaviors represent long-term strategies for building resilience, whereas manipulative behaviors represent short-term strategies with uncertain consequences for resilience, vulnerability, and the sustainability of social–ecological systems. Of greatest significance; however, is that manipulative strategies have the potential to avoid authentic experiences of system dynamics, obscure valuable learning opportunities, create adverse path dependencies, and lessen the likelihood of effective adaptation in future contexts.

  10. Terrestrial ecosystem responses to global change: A research strategy

    1998-09-01

    Uncertainty about the magnitude of global change effects on terrestrial ecosystems and consequent feedbacks to the atmosphere impedes sound policy planning at regional, national, and global scales. A strategy to reduce these uncertainties must include a substantial increase in funding for large-scale ecosystem experiments and a careful prioritization of research efforts. Prioritization criteria should be based on the magnitude of potential changes in environmental properties of concern to society, including productivity; biodiversity; the storage and cycling of carbon, water, and nutrients; and sensitivity of specific ecosystems to environmental change. A research strategy is proposed that builds on existing knowledge of ecosystem responses to global change by (1) expanding the spatial and temporal scale of experimental ecosystem manipulations to include processes known to occur at large scales and over long time periods; (2) quantifying poorly understood linkages among processes through the use of experiments that manipulate multiple interacting environmental factors over a broader range of relevant conditions than did past experiments; and (3) prioritizing ecosystems for major experimental manipulations on the basis of potential positive and negative impacts on ecosystem properties and processes of intrinsic and/or utilitarian value to humans and on feedbacks of terrestrial ecosystems to the atmosphere.

  11. How does a change in the control room design affect diagnostic strategies in nuclear power plants?

    International Nuclear Information System (INIS)

    Recently, main control rooms have been considerably changed by modern computer techniques. Some of the features that distinguish digital control rooms from conventional, analog rooms in nuclear power plants include advanced alarm systems, graphic information display systems, computerized procedure systems, and soft control. These features can bring changes in operator tasks, changing the characteristics of tasks or creating new tasks for operators. It is especially expected that these features may bring out changes in the operator's diagnostic tasks and strategies in a digital control room as compared with an analog control room. This study investigates the differences in the operator's diagnostic tasks and strategies in analog and digital control rooms. This study also attempts to evaluate how new systems in a digital control room affect diagnostic strategies. Three different approaches, which are complementary, are used to identify diagnostic strategies in the digital control room and in the analog control room: (1) observation in the simulator, (2) interview with operators, and (3) a literature review. The results show that the digital control room introduces new diagnosis strategies compared with the analog control room while also changing the characteristics of the strategies, mostly by gaining more support from the computerized system.

    A linearization-based feedback-control strategy for a SEIR epidemic model is discussed. The vaccination objective is the asymptotically tracking of the removed-by-immunity population to the total population while achieving simultaneously the remaining population (i.e. susceptible plus infected plus infectious) to asymptotically tend to zero. The disease controlpolicy is designed based on a feedback linearization technique which provides a general method to generate families of vaccination policies with sound technical background.

    The circumpolar north is uniquely vulnerable to the health impacts of climate change. While international Arctic collaboration on health has enhanced partnerships and advanced the health of inhabitants, significant challenges lie ahead. One Health is an approach that considers the connections between the environment, plant, animal and human health. Understanding this is increasingly critical in assessing the impact of global climate change on the health of Arctic inhabitants. The effects of climate change are complex and difficult to predict with certainty. Health risks include changes in the distribution of infectious disease, expansion of zoonotic diseases and vectors, changing migration patterns, impacts on food security and changes in water availability and quality, among others. A regional network of diverse stakeholder and transdisciplinary specialists from circumpolar nations and Indigenous groups can advance the understanding of complex climate-driven health risks and provide community-based strategies for early identification, prevention and adaption of health risks in human, animals and environment. We propose a regional One Health approach for assessing interactions at the Arctic human-animal-environment interface to enhance the understanding of, and response to, the complexities of climate change on the health of the Arctic inhabitants.

    2015-01-01

    Achieving World Health Organization air quality targets and aspirational fuel savings targets through clean cooking solutions will require high usage rates of high-performing products and low usage rates of traditional stoves. Catalyzing this shift is challenging as fuel and stove use practices associated with new technologies generally differ from those used with traditional technologies. Accompanying this shift with ventilation improvements can help further reduce exposure to emissions of health damaging pollutants. Behavior change strategies will be central to these efforts to move users to new technologies and minimize exposure to emissions. In this article, the authors show how behavior change can be linked to quantitative guidance on stove usage, household ventilation rates, and performance. The guidance provided here can help behavior change efforts in the household energy sector set and achieve quantitative goals for usage and ventilation rates. PMID:25839198

    2015-12-01

    Full Text Available Studies have shown that while East Asians focused on the center of the face to recognize identities, participants adapted their strategy by focusing more on the eyes to identify emotions, suggesting that the eyes may contain salient information pertaining to emotional state in Eastern cultures. However, Western Caucasians employ the same strategy by moving between the eyes and mouth to identify both identities and emotions. Malaysian Chinese have been shown to focus on the eyes and nose more than the mouth during face recognition task, which represents an intermediate between Eastern and Western looking strategies. The current study examined whether Malaysian Chinese continue to employ an intermediate strategy or shift towards an Eastern or Western pattern (by fixating more on the eyes or mouth respectively during an emotion recognition task. Participants focused more on the eyes, followed by the nose then mouth. Directing attention towards the eye region resulted in better recognition of certain own- than other-race emotions. Although the fixation patterns appear similar for both tasks, further analyses showed that fixations on the eyes were reduced whereas fixations on the nose and mouth were increased during emotion recognition, indicating that participants adapt looking strategies based on their aims.

    Osendarp, Saskia J M; Roche, Marion L

    2016-01-01

    Improving infant and young child feeding (IYCF) practices, including breastfeeding and complementary feeding, has been identified as one of the most effective interventions to improve child survival, stunting and wasting. Evidence from randomized controlled trials suggests that effective promotion of breastfeeding and complementary feeding, with or without food provision, has the potential to improve IYCF practices and child nutrition. However, in many countries, breastfeeding practices and complementary feeding practices are still far from optimal. The lack of implementation of available, effective, affordable interventions in scale-up programs is in part attributed to a lack of innovative, creative and effective behavioral change strategies that enable and encourage caregivers. Successful behavioral change strategies should be based on a rigorous situational analysis and formative research, and the findings and insights of formative research should be used to further design interventions that address the identified barriers and enablers, to select delivery channels, and to formulate appropriate and effective messages. In addition, successful behavioral change interventions should a priori define and investigate the program impact pathway to target behavioral change and should assess intermediary behavioral changes and indicators to learn why the expected outcome was achieved or not achieved by testing the program theory. The design of behavioral change communication must be flexible and responsive to shifts in societies and contexts. Performance of adequate IYCF also requires investments to generate community demand through social mobilization, relevant media and existing support systems. Applying these principles has been shown to be effective in improving IYCF practices in Vietnam, Bangladesh and Ethiopia and is recommended to be adopted by other programs and countries in order to accelerate progress in improving child nutrition.

    This paper presents a vaccination-based control strategy for a SEIR (susceptible plus infected plus infectious plus removed populations) propagation disease model. The model takes into account the total population amounts as a refrain for the illness transmission since its increase makes more difficult contacts among susceptible and infected. The control objective is the asymptotically tracking of the removed-by-immunity population to the total population while achieving simultaneously the remaining population (i.e. susceptible plus infected plus infectious) to asymptotically tend to zero.

    Full Text Available The results of a survey on 153 Slovenian manufacturing companies show that companies implement environmental strategies primarily as a refl ection of the commitment of their top management, followed by public concern, regulatory forces and expected competitive advantage. They report a relatively high level of implementation of the corporate environmental strategy while, among functional strategies, environmental issues are most commonly included in the production and marketing strategies, followed by purchasing and personnel strategies. Large companies develop and execute environmental strategies to a greater extent than small companies. The results also reveal a positive but very weak relationship between environmental strategies and company performance.

    2013-01-01

    In this communication, a simple mechanism in the optional public goods game is experimentally investigated using two experimental settings; and first time, the cyclic strategy pattern in full state space is demonstrated by means of velocity. It is, furthermore, elaborated that the strategies of cooperation, defection and nonparticipant form a Rock-Paper-Scissors type cycle, and the cycle of three strategies are persistent over 200 rounds. This cycle is very similar to the cycle given by evolutionary dynamics e.g. replicator dynamics. The mechanism that nonparticipant can sustain cooperation is driven by the Rock-Paper-Scissors type of cyclic dominance in the three strategies. That is, if the cycle is existent, the cooperation will always sustain. Meanwhile, the distribution of social states changes in the state space and from cooperation as the most frequent strategy to defection and, from defection to nonparticipant, forms a clear rotation path in a long run. These results seem to implicate that the evolutio...

  4. Chernobyl tenth anniversary: strategy for response, organisation, examples and results

    International Nuclear Information System (INIS)

    Each anniversary of the nuclear accident at Chernobyl, Ukraine, in April 1986, is accompanied by considerable activity on the part of the press and the anti-nuclear industry. In the course of such activity, many distortions of the true situation in the area are promulgated. It was clear to the nuclear industry that the tenth anniversary would be especially difficult. Hence the international nuclear community, under the leadership of the British Nuclear Industry Forum, constituted a Task Force to consider responses to the anniversary. This paper describes the essential steps in setting up the Task Force; discusses the main elements of the strategy which emerged, including the Chernobyl Fact Sheets, the identification of credible third parties who could explain key issues with the media, and the secondment of a British press officer to the plant to coordinate international visits; and evaluate press response to the anniversary in comparison with previous anniversaries.

Strict doctrinal interpretation of Koranic text is not a new phenomenon, contrary to what some reports in the mass media might suggest. Its roots stretch back at least as far as the 1800s with the outbreak of violent conflicts between those urging a stricter, scripturalist application of Islam, and those adhering to traditionalist and colonialist ideologies --culminating in the Padri war of West Sumatra of 1821-38. Indicating an ostensible continuity of ideology, modern extremist ideologues, such as Abu Bakar Bashir, urge their followers toward violent conflict and terrorist actions based on an ideology of strict “Middle Eastern” interpretation of fundamental Islamic tenets. This paper argues that the strategies of those carrying out radical and violent ideologies are undergoing change, as are the strategies of the authorities tasked with combating them. Radical groups have displayed a shift away from large-scale, attacks on symbolic foreign targets towards low-level violence primarily aimed at law enforcement authorities. Authorities, on the other hand, have shown a greater tendency to shoot dead those suspected of involvement with violent radical groups. This paper will examine the changing strategies of violent radical groups and the continuity, and evolution, of the underlying Islamic ideology that provides religious justification for their violent acts. The paper will argue that engaging Indonesia’s politically active youth in an ideological dialogue on Islamism and democracy provides the best prospect for disengagement from, and breaking the cycle of recruitment for, radical violence and terrorism.[Proses panjang Islamisasi di Indonesia telah menghasilkan kekuatan transformatif di

    This paper introduces the recent European Aerosol Research Lidar Network (EARLINET) quality-assurance efforts at instrument level. Within two dedicated campaigns and five single-site intercomparison activities, 21 EARLINET systems from 18 EARLINET stations were intercompared between 2009 and 2013. A comprehensive strategy for campaign setup and data evaluation has been established. Eleven systems from nine EARLINET stations participated in the EARLINET Lidar Intercomparison 2009 (EARLI09). In this campaign, three reference systems were qualified which served as traveling standards thereafter. EARLINET systems from nine other stations have been compared against these reference systems since 2009. We present and discuss comparisons at signal and at product level from all campaigns for more than 100 individual measurement channels at the wavelengths of 355, 387, 532, and 607 nm. It is shown that in most cases, a very good agreement of the compared systems with the respective reference is obtained. Mean signal deviations in predefined height ranges are typically below ±2 %. Particle backscatter and extinction coefficients agree within ±2 × 10-4 km-1 sr-1 and ± 0.01 km-1, respectively, in most cases. For systems or channels that showed larger discrepancies, an in-depth analysis of deficiencies was performed and technical solutions and upgrades were proposed and realized. The intercomparisons have reinforced confidence in the EARLINET data quality and allowed us to draw conclusions on necessary system improvements for some instruments and to identify major challenges that need to be tackled in the future.

  8. Managing organizational change: strategies for the female health care supervisor.

    1990-07-01

    In responding to resistance to change in the current health care organization, the new female supervisor can learn to support her staff in encountering and accepting these changes. The strategies and skills discussed above are characteristic of a supervisory style that may naturally occur for women, but also can be incorporated into the leadership style of men in health care management today. Health care leaders of tomorrow must work from an androgynous framework in which the behavior patterns and responses of each gender are learned and used appropriately by both men and women. Sargent suggests that the best managers are androgynous and that this is the inevitable wave of the future. Whether man or woman, a supervisor should learn, accept, and use methods that are characteristic of both sexes to be successful in managing people. Women and men must learn from each other's strengths and share these diverse skills. Given that women now outnumber men in health care management positions and organizations are changing to a more nurturing environment, the androgynous supervisor will be the successful leader of the future. Finally, women in health care supervisory positions have the potential to bring change where it is badly needed. Women in these roles often have a system wide view of health care policy issues that recognizes less federal commitment to social programs. Many women in health care positions believe that the issues of children, women, the elderly, the poor, and the homeless need focused attention. The growing number of women in health care supervisory and leadership roles is an important factor in changing national health policy for the benefit of these groups.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:10105044

    This presentation described how demographic trends are changing the energy industry. Duke Energy acquired Westcoast Energy in March 2002 and must attract and retain a skilled workforce to maintain its newly acquired and very large infrastructure. Duke Energy has committed $1.88 million over 3 years to northern opportunities through partnerships with educators, community organizations, government agencies and industry. This paper emphasizes the need for a new focus on workforce planning to ensure that staffing needs are met. It described how to use demographics to identify recruitment needs within a company, and what to look for in data. It also described how to make sure that a recruitment strategy is tailored to various demographic groups. Energy companies are attracting young workers through apprenticeship programs, training and development programs, and other incentives. figs.

  10. Complexity Results and Approximation Strategies for MAP Explanations

    CERN Document Server

    Darwiche, A; 10.1613/jair.1236

    2011-01-01

    MAP is the problem of finding a most probable instantiation of a set of variables given evidence. MAP has always been perceived to be significantly harder than the related problems of computing the probability of a variable instantiation Pr, or the problem of computing the most probable explanation (MPE). This paper investigates the complexity of MAP in Bayesian networks. Specifically, we show that MAP is complete for NP^PP and provide further negative complexity results for algorithms based on variable elimination. We also show that MAP remains hard even when MPE and Pr become easy. For example, we show that MAP is NP-complete when the networks are restricted to polytrees, and even then can not be effectively approximated. Given the difficulty of computing MAP exactly, and the difficulty of approximating MAP while providing useful guarantees on the resulting approximation, we investigate best effort approximations. We introduce a generic MAP approximation framework. We provide two instantiations of the frame...

  14. China's strategy for energy development and climate change mitigation

    International Nuclear Information System (INIS)

    In recent years, China has made great efforts in energy saving and carbon emission reduction by pushing forward domestic sustainable development along with global climate change mitigation. The efforts have paid off with a dramatic decrease in carbon intensity. Nevertheless, China is still confronted with tough challenges in emission control due to the fast pace of industrialization, large total historical emission and high growth rate of emissions. Therefore, China should give priority to energy saving by improving energy efficiency and sectoral structure adjustment and upgrade, and develop sustainable and renewable energy to optimize energy mix and its carbon content. China should continue to regard significant reduction of energy intensity and carbon intensity as the main objective in the near future, strive to achieve peak emissions around 2030, and realize a relatively sharp emissions reduction by 2050 in order to address climate change to meet the goal of making the warming less than 2°. During the 12th Five Year Plan (FYP), China will further strengthen measures to control the amount of energy consumption, establish a statistics, accounting and evaluation system of carbon emissions, and promote a market-based carbon emissions trading mechanism to facilitate the low-carbon transformation of China's economy. - Highlights: ► This paper studies China's strategy for energy development and climate change mitigation. ► We suggest that China should focus on reducing the energy intensity and carbon intensity of GDP, and optimization of energy mix in the near term. ► In the long term, China should achieve the peak emission around 2030, and realize a relative sharp emission reduction by 2050. ► The paper also concludes some important measures which China should take during the 12th Five-Year-Plan (2011–2015).

    The spatial distribution of water deficit and maize yield deficit across Europe has been compared between current and expected climatic conditions in the near future (time window 2030). Maize yields and water requirements were simulated using the WOFOST (World Food Studies) crop growth model. In our study, the priority has been given to future projections of the A1B emission scenario produced within the ENSEMBLE project: HadRM3 RCM nested within the HADCM3 GCM (HADLEY) and HIRHAM5 RCM nested within ECHAM5 GCM (ECHAM). The two realizations can be considered as warm (HADLEY) and cold (ECHAM5) according to simulated temperature in the near future and therefore represent the extremes in air temperature change within those analyzed in ENSEMBLES project, allowing us to evaluate the largest range of uncertainty in weather inputs to the impact model. In addition, we also explored the advantages of different irrigation strategies for the target crop to offset climate change impacts. In wake of limited amount of water availability for agriculture purposes, we explored effectiveness of three different irrigation strategies on maize yield over Europe, namely full, deficit and supplemental irrigation. The results of our study indicate that the maize yield under rainfed conditions is expected to decrease over the Southern Europe as well as regions around the Black Sea during the 2030s under both climate model realizations. Water deficit is expected to increase especially in the Mediterranean, whereas slightly less in parts of Central and Western Europe. However, adaptation strategies followed in this study negate the detrimental effect of climate change and result in an increased maize yield. Three irrigation strategies have been simulated differing in timing of water application and in the total volume of water supplied during the growing season. The results show that yields, achieved using deficit and full irrigation strategies, are not significantly different. Hence, at least

  1. Terrestrial Ecosystem Responses to Global Change: A Research Strategy

    Energy Technology Data Exchange (ETDEWEB)

    Ecosystems Working Group,

    1998-09-23

    Uncertainty about the magnitude of global change effects on terrestrial ecosystems and consequent feedbacks to the atmosphere impedes sound policy planning at regional, national, and global scales. A strategy to reduce these uncertainties must include a substantial increase in funding for large-scale ecosystem experiments and a careful prioritization of research efforts. Prioritization criteria should be based on the magnitude of potential changes in environmental properties of concern to society, including productivity; biodiversity; the storage and cycling of carbon, water, and nutrients; and sensitivity of specific ecosystems to environmental change. A research strategy is proposed that builds on existing knowledge of ecosystem responses to global change by (1) expanding the spatial and temporal scale of experimental ecosystem manipulations to include processes known to occur at large scales and over long time periods; (2) quantifying poorly understood linkages among processes through the use of experiments that manipulate multiple interacting environmental factors over a broader range of relevant conditions than did past experiments; and (3) prioritizing ecosystems for major experimental manipulations on the basis of potential positive and negative impacts on ecosystem properties and processes of intrinsic and/or utilitarian value to humans and on feedbacks of terrestrial ecosystems to the atmosphere. Models and experiments are equally important for developing process-level understanding into a predictive capability. To support both the development and testing of mechanistic ecosystem models, a two-tiered design of ecosystem experiments should be used. This design should include both (1) large-scale manipulative experiments for comprehensive testing of integrated ecosystem models and (2) multifactor, multilevel experiments for parameterization of process models across the critical range of interacting environmental factors (CO{sub 2}, temperature, water

    A deterministic simulation was conducted to assess the effects of sexed semen utilization strategies on age at first calving (AFC). Four different strategies were implemented on dairy heifers: continuous use of conventional semen only (CC), continuous use of sexed semen only (SS), utilization of sexed semen for both the first and second services with conventional semen afterwards (S2), and utilization of sexed semen for the first service with conventional semen afterwards (S1). Results indicated that continuous utilization of sexed semen led to the greatest AFC; however at high conception rates, strategies displayed negligible differences on AFC. Increases in estrus detection rate had the greatest effects on decreasing AFC of the SS scenarios. Negative effect of sexed semen on AFC increased when the effect of low estrus detection rate was combined with low conception rate of sexed semen. Results indicated that in the case of access to sexed semen conception rate, prediction of AFC is possible by quadratic polynomial or exponential equations, depending to the applied breeding strategy. Simultaneous utilization of sexed and conventional semen in a herd did not make a substantial change in AFC when a low percentage of sexed semen was employed. Increasing the contribution of different sexed semen strategies led to higher AFC variation, especially for the SS strategy. AFC of strategies that utilize sexed semen is highly dependent on the conception rate, estrus detection rate and the contribution of sex sorted semen in the total number of inseminations of the heifer herd.

  9. Maintenance strategies and safety on a deregulated market. Mapping of changes in maintenance strategies and their possible consequences

    International Nuclear Information System (INIS)

    The overall purpose of the project was to make a survey of the changes in the Swedish nuclear power plants over the last five years. There is a risk that nuclear power companies after a deregulation will focus especially on reducing operation and maintenance costs and that the changes could have a negative effect on the reactor safety. The task has involved summarising the actual changes, describing the present situation, the need for future development and the differences between the plants as well as identifying possible reactor safety related risks. The survey has been carried out in a broad perspective, studying the changes in equipment, maintenance strategies and the work situation of the staff. Three case studies were carried out at the Swedish nuclear power plants. Documentation from the companies has been analysed and a selection of in total 27 'informed' employees in different positions have been interviewed in total. The project also included a fourth case study concerning railway traffic. This branch of business is interesting because of its longer experience on a deregulated and competitive market. Conclusions concerning the companies individually as well as similarities and differences between them are presented in this report. Results: There have been more changes both in strategy and organisation in the last five years than during the preceding 5-10-year-period and the pace has been relatively rapid. The deregulation of the electricity market was implemented January 1997 and became the main motive force for the changes. The staffing has been reduced or unchanged and the work demands have increased. The maintenance skills have been redistributed within the organisation. New methods and equipment, i.e. RCM, and programmable systems make increased demands for analytical and theoretical competence. In the short term, job satisfaction and motivation have in some cases been negatively influenced by the new organisation forms, according to several of the

    The present study explored whether distress reduction in response to strong negative emotions, a putative transdiagnostic mechanism of action, is facilitated by mindfulness strategies. Seven patients (mean age=31.14years, SD=12.28, range 19-48 years, 43% female, 86% Caucasian) with heterogeneous anxiety disorders (i.e., panic disorder with or without agoraphobia, social anxiety, generalized anxiety) were assigned a randomized order of weeklong blocks utilizing either mindfulness- or avoidance-based strategies while ascending a 6-week emotion exposure hierarchy. Participants completed three exposures per block and provided distress and avoidance use ratings following each exposure. Anxiety severity, distress aversion, and distraction/suppression tendencies were also assessed at baseline and the conclusion of each block. Visual, descriptive, and effect size results showing exposures utilizing mindfulness were associated with higher overall distress levels, compared with those utilizing avoidance. Within blocks, the majority of participants exhibited declining distress levels when employing mindfulness strategies, as opposed to more static distress levels in the avoidance condition. Systematic changes in anxiety severity, distress aversion, and distraction/suppression were not observed. These results suggest mindfulness strategies may be effective in facilitating emotion exposure; however, a minimum dosage may be necessary to overcome initial distress elevation. Potential transdiagnostic change mechanisms and clinical implications are discussed. PMID:26956654

  11. Strategies for Hydrology Teaching for a Changing World

    2010-05-01

    Hydrology as a science has undergone dramatic changes in the past 80 years. However, as evidenced by the text books that are being used and conversations with many educators, it appears that hydrologic education has not kept pace. The legacy of the past growth of hydrology is reflected in the materials and methods used in hydrology teaching as practiced now. Current teaching methods tend to present a mix of empirical approaches (e.g., data analysis, multiple regressions), systems approaches (e.g., unit hydrograph methods, bucket models), and process theories (e.g., infiltration, runoff generation, evaporation, channel flow), often in the form of recipes or skill sets. However, they represent an old paradigm where hydrology was seen as dealing with the movement of water through and over a static earth, aimed at solving one or a combination of separate boundary value problems. However at least since the 1990s there is a new research paradigm operating, which treats hydrology as a distinct geoscience, which does not just deal with the movement of water, but with an interacting holistic earth system that includes not just hydrological but also biogeochemical, ecological and human subsystems. Global change increasingly dictates that this geoscience paradigm be further extended to include highly non-stationary, evolutionary behaviors strongly governed by human-nature interactions. Shouldn't this be recognized in our teaching, and if so how can we achieve it? In this talk I will outline broad strategies we can adopt that could pave the way for a paradigm shift also in the way we teach hydrology. Beyond the essential skills that we have always taught, some of the new skill sets we need to impart are, amongst many others: learning to read the landscape, learning from patterns in the data, including patterns in the landscape and in the atmosphere (e.g., channel morphology, vegetation patterns, climatic patterns), comparative studies as opposed to place-based studies

    For a long time, treatment of peritoneal metastases (PM) was mostly palliative and thus, this status was link with "terminal status/despair". The current multimodal treatment strategy, consisting of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC), has been strenuously achieved over time, but seems to be the best treatment option for PM patients. As we reviewed the literature data, we could emphasize some milestones and also, controversies in the history of proposed multimodal treatment and thus, outline the philosophy of this approach, which seems to be an unusual one indeed. Initially marked by nihilism and fear, but benefiting from a remarkable joint effort of human and material resources (multi-center and -institutional research), over a period of 30 years, CRS and HIPEC found their place in the treatment of PM. The next 4 years were dedicated to the refinement of the multimodal treatment, by launching research pathways. In selected patients, with requires training, it demonstrated a significant survival results (similar to the Hepatic Metastases treatment), with acceptable risks and costs. The main debates regarding CRS and HIPEC treatment were based on the oncologists' perspective and the small number of randomized clinical trials. It is important to statement the PM patient has the right to be informed of the existence of CRS and HIPEC, as a real treatment resource, the decision being made by multidisciplinary teams.

    Climate change is a global and local challenge to both sustainable livelihoods and economic development. Tanzania as other countries of the world has been affected. Several studies have been conducted on farmers' perceptions and adaptation to climate change in the country, but little attention has been devoted to forest adjacent households in humid areas. This study assessed this gap through assessing forest adjacent households' voices on perceptions and adaptation strategies to climate change in Kilombero District, Tanzania. Data collection involved key informant interviews, focus group discussions and household questionnaires. Results showed that the majority of households perceived changed climate in terms of temperature increase, unpredictable rainfall, frequent occurrence of floods, increased dry spells during rainy season coupled with decreased water sources and emergence of new pests and diseases. The perceived change in climate has impacted agriculture productivity as the main livelihood source. Different coping and adaptation strategies are employed. These are; crop diversification, changing cropping calendar, adopting modern farming technologies, and increasing reliance on non-timber forest products. These strategies were positively and significantly influenced by socio-economic factors including household size, residence period, land ownership and household income. The study concludes that, there are changes in climatic conditions; and to respond to these climatic changes, forest adjacent households have developed numerous coping and adaptation strategies, which were positively and significantly influenced by some socio-economic factors. The study calls for actual implementation of local climate change policies and strategies in order to enhance adaptive capacity at household level. PMID:27390633

  17. Constitutive versus responsive gene expression strategies for growth in changing environments.

    Directory of Open Access Journals (Sweden)

    Nico Geisel

    Full Text Available Microbes respond to changing environments by adjusting gene expression levels to the demand for the corresponding proteins. Adjusting protein levels is slow, consequently cells may reach the optimal protein level only by a time when the demand changed again. It is therefore not a priori clear whether expression "on demand" is always the optimal strategy. Indeed, many genes are constitutively expressed at intermediate levels, which represents a permanent cost but provides an immediate benefit when the protein is needed. Which are the conditions that select for a responsive or a constitutive expression strategy, what determines the optimal constitutive expression level in a changing environment, and how is the fitness of the two strategies affected by gene expression noise? Based on an established model of the lac- and gal-operon expression dynamics, we study the fitness of a constitutive and a responsive expression strategy in time-varying environments. We find that the optimal constitutive expression level differs from the average demand for the gene product and from the average optimal expression level; depending on the shape of the growth rate function, the optimal expression level either provides intermediate fitness in all environments, or maximizes fitness in only one of them. We find that constitutive expression can provide higher fitness than responsive expression even when regulatory machinery comes at no cost, and we determine the minimal response rate necessary for "expression on demand" to confer a benefit. Environmental and inter-cellular noise favor the responsive strategy while reducing fitness of the constitutive one. Our results show the interplay between the demand-frequency for a gene product, the genetic response rate, and the fitness, and address important questions on the evolution of gene regulation. Some of our predictions agree with recent yeast high throughput data, for others we propose the experiments that are needed

    Climate change resulted in changes in crop growth duration and planting structure, northward movement of planting region, and more severe plant diseases and insect pests in Northwest China. It caused earlier seeding for spring crop, later seeding for autumn crop, accelerated crop growth, and reduced mortality for winter crop. To adapt to climate change, measures such as optimization of agricultural arrangement, adjustment of planting structure, expansion of thermophilic crops, and development of water-saving agriculture have been taken. Damaging consequences of imbalance between grassland and livestock were enhanced. The deterioration trend of grassland was intensified; both grass quantity and quality declined. With overgrazing, proportions of inferior grass, weeds and poisonous weeds increased in plateau pastoral areas. Returning farmland to grazing, returning grazing to grassland, fence enclosure and artificial grassland construction have been implemented to restore the grassland vegetation, to increase the grassland coverage, to reasonably control the livestock carrying capacity, to prevent overgrazing, to keep balance between grassland and livestock, and to develop the ecological animal husbandry. In Northwest China, because the amount of regional water resources had an overall decreasing trend, there was a continuous expansion in the regional land desertification, and soil erosion was very serious. A series of measures, such as development of artificial precipitation (snow), water resources control, regional water diversion, water storage project and so on, were used effectively to respond to water deficit. It had played a certain role in controlling soil erosion by natural forest protection and returning farmland to forest and grassland. In the early 21st century, noticeable achievements had been made in prevention and control of desertification in Northwest China. The regional ecological environment has been improved obviously, and the desertification trend

    The framework convention on climate change, signed by more than 150 governments worldwide in June 1992, calls on parties to the convention undertaken inventories of national sources and sinks of greenhouse gases and to develop plans for responding to climate change. The energy sector is comprised of the major energy demand sectors (industry, residential and commercial, transport and agriculture), and the energy supply sector, which consists of resource extraction, conversion, and delivery of energy products. Greenhouse Gas (GHG) emissions occur at various points in the sector, from resource extraction to end use application, and accordingly, options for mitigation exist at various points. In most countries, will be a major focus of GHG mitigation analysis. The primary focus of this paper is on the identification of strategies that can mitigate climate changes on the basis of integrated energy planing analysis. The overall approach follows a methodology developed by the U.S. Country Studies Program under the framework of the Convention's commitments. It involves the development of scenarios based on energy uses and evaluation of specific technologies that can satisfy demands for energy services. One can compare technologies based on their relative cost to achieve a unit of GHG reduction and other features of interest. This approach gives equal weight to both energy supply and energy demand options. A variety of screening criteria including indicators of cost-effectiveness as well as non-economic analysis concerns, can be used to identify and assess promising options, which can then be combined to create one or more scenarios. Mitigation scenarios are evaluated against the backdrop of a baseline scenario, which simulates assumed to take place in the absence of mitigation efforts. Mitigation scenarios can be designed to meet specific emission reduction targets or to simulate the effect of specific policy inventions. The paper ends with an application using a

  3. Experimental Investigation of Human Adaptation to Change in Agent's Strategy through a Competitive Two-Player Game

    We conducted an experimental investigation on human adaptation to change in an agent's strategy through a competitive two-player game. Modeling the process of human adaptation to agents is important for designing intelligent interface agents and adaptive user interfaces that learn a user's preferences and behavior strategy. However, few studies on human adaptation to such an agent have been done. We propose a human adaptation model for a two-player game. We prepared an on-line experimental system in which a participant and an agent play a repeated penny-matching game with a bonus round. We then conducted experiments in which different opponent agents (human or robot) change their strategy during the game. The experimental results indicated that, as expected, there is an adaptation phase when a human is confronted with a change in the opponent agent's strategy, and adaptation is faster when a human is competing with robot than with another human.

  4. Mathematical Rigor vs. Conceptual Change: Some Early Results

    Results from two different pedagogical approaches to teaching introductory astronomy at the college level will be presented. The first of these approaches is a descriptive, conceptually based approach that emphasizes conceptual change. This descriptive class is typically an elective for non-science majors. The other approach is a mathematically rigorous treatment that emphasizes problem solving and is designed to prepare students for further study in astronomy. The mathematically rigorous class is typically taken by science majors. It also fulfills an elective science requirement for these science majors. The Astronomy Diagnostic Test version 2 (ADT 2.0) was used as an assessment instrument since the validity and reliability have been investigated by previous researchers. The ADT 2.0 was administered as both a pre-test and post-test to both groups. Initial results show no significant difference between the two groups in the post-test. However, there is a slightly greater improvement for the descriptive class between the pre and post testing compared to the mathematically rigorous course. There was great care to account for variables. These variables included: selection of text, class format as well as instructor differences. Results indicate that the mathematically rigorous model, doesn't improve conceptual understanding any better than the conceptual change model. Additional results indicate that there is a similar gender bias in favor of males that has been measured by previous investigators. This research has been funded by the College of Science and Mathematics at James Madison University.

    2016-03-01

    Full Text Available The study discusses local farmers’ strategies of coping with and building resilience against the negative impact of climate change. Information for the discussion was from data collected using a set of structured questionnaires from interviews scheduled with 128 farmers. The questionnaire was based on previous literature and direct reconnaissance interview with farmers, which culminated in 13 strategies used for the study being reported. For each question, respondents were asked to choose their best and worst strategies. Thus, the difference between the best and worst strategies consistent with random utility theory has been used for the modelling. Results show that semi-transhumance, various handicrafts making, rural migration, small-scale vegetable production and small-scale river exploitation were the most important strategies identified, whilst water transport and vending, shifting cultivation, gypsum mining, gathering and trading of wild fruits and edible plants as well as cattle and sheep fattening were the least appreciated strategies identified amongst the farmers facing climate change. These findings are therefore imperative for planning farmers’ capacity-building and resilience against climate change projects to ensure sustainability in the study area.Keywords: Farmers’ adaptation strategies; Climate change resilience; Kaou

    Full Text Available The climate is changing and global mean temperatures have increased this is expected to have profound effects on food security. Long-term changes in climate will disproportionately affect tropical regions, meaning poor farmers in Sub-Saharan Africa will likely bear the brunt of adverse impacts. Adaptation plays an important role in reducing vulnerability to climate change and is therefore critical and of concern in developing countries, particularly in Africa where vulnerability is high because ability to adapt is low. This study examined farmers’ strategies for adapting to climate change in Ogbomoso agricultural zone of Oyo State of Nigeria. One hundred and fifty farmers were interviewed to obtain information from using a multistage sampling procedure. The results of the study showed that the types of climate change identified in the study area were delayed on-set of rainfall (38.0 percent, higher temperature (20.0 percent and less rain (17.3 percent. The outcome of climate change were food shortage (41.3percent, decline in livestock yield (30.7 percent, decline in crop yield (28.7 percent and death of livestock (16.0 percent. The identified actions taken to address climate change are growing a new crop (57.4 percent, adoption of drought tolerant/ resistance crop varieties (50.0 percent, diversification from crops to livestock production (40.7 percent and using of new land management practices. The long-term improvement investments commonly adapted in the study area were tree planting/agroforestry, mulching/surface cover, improved fallowing and fallowing.The study concluded that household size, extension visits and non-farm income significantly impact on the various strategies used in adaptation to climate change.

    Private companies will play a critical role in successful efforts to address climate change, due to both their role as major emitters of greenhouse gases and to their capacity to invest in mitigation technologies. However, relatively little is known about the triggers for change in corporate behaviour, which are at the basis of corporate decisions to support or oppose policy initiatives. In the title project it has been investigated what strategies - and why and how - specific industrial sectors develop to limit greenhouse gas emissions. The objective was to provide information of relevance to the sixth Convention of Parties (CoP6) that is to be held in The Hague, Netherlands, November 2000. In a USA-Europe co-operation, researchers have analysed emerging climate strategies in the oil industry, the automobile industry, the chemical industry and the banking and insurance sector. Together, these sectors are the most important players in the climate policy debate. Special attention has been paid to the questions whether strategies of European Union (EU)- based corporations differ systematically from US-based corporations. Results show rather sectorial specific developments. In most sectors, i.e. oil, automobile and banks. European corporations generally tend to have more advanced policies than their US counterparts, but this does not apply to chemical companies. Corporate strategies appear to be highly determined by a combination of market situation in their home country and of access to alternative technologies. In the automobile industry, the USA and Europe show convergent strategies. In the other sectors, convergence is not clearly visible. 100 refs.

  8. Biomechanical changes in endothelial cells result from an inflammatory response

    2012-02-01

    During periods of infection and disease, the immune system induces the release of TNF-α, an inflammatory cytokine, from a variety of cell types, such as macrophages. TNF-α, while circulating in the vasculature, binds to the apical surface of endothelial cells and causes a wide range of biological and mechanical changes to the endothelium. While the biological changes have been widely studied, the biomechanical aspects have been largely unexplored. Here, we investigated the biomechanical changes of the endothelium as a function of TNF-α treatment. First, we studied the traction forces applied by the endothelium, an effect that is much less studied than others. Through the use of traction force microscopy, we found that TNF-α causes an increase in traction forces applied by the endothelial cells as compared to non-treated cells. Then, we investigated cell morphology, cell mechanics, migration, and cytoskeletal dynamics. We found that in addition to increasing applied traction forces, TNF-α causes an increase in cell area and aspect ratio on average, as well as a shift in the organization of F-actin filaments within the cell. Combining these findings together, our results show that an inflammatory response heavily impacts the morphology, cell mechanics, migration, cytoskeletal dynamics, and applied traction forces of endothelial cells.

    The intention of the inquiry was to investigate the opinion within the scientific community about climate change questions that are believed to be already well solved in the public opinion. 32 questions were formulated that deal with 12 main assumptions about the existence, the predictability and the impacts of climate changes due to an artificially enhanced greenhouse effect. The possibilities to answer reached from `sure yes`, over `guess yes`, `not answerable or no opinion` to `guess no` and `sure no`. There were additional questions about the way the answers were gained: `by own research`, `by studying scientific literature or discussion with colleagues` and `by mass media consumption`. In the following some of the key assumptions about climate change topics will be discussed as the predictability of future evolution of climate by climate models and the detectability of an artificially enhanced greenhouse effect in climate time series. The other assumptions can be shown here only in the form of a comprehensive overview. In a very comprehensive form the results of the inquiry could be described in the following: A weak majority of climatologists believe today`s climate models to be able to describe a greenhouse gas induced climate change in global scale - much less in regional scale and not in local scale. A majority of climatologists believe an anthropogenic greenhouse gas forced climate and its impacts to be developing in the future but not already at present. The shape of the opinion spectra is in most cases far from that of a scientifically solved problem - a lot of work still has to be done

  10. The influence of organizational culture on organizational preferences towards the choice of organizational change strategy

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available Organizational culture, through its assumptions, values, norms and symbols, determines the way in which the members of an organization perceive and interpret the reality within and around their organization, as well as the way they behave in that reality. For this reason we may assume that organizational culture has an impact on the way in which an organization changes, and that matching of organizational culture and change strategy will improve the efficiency of the change process. In this paper specific hypotheses about the causal relationship between certain types of organizational culture and certain change strategies are formulated. Types of organizational culture are differentiated according to Handy’s and Trompenaars’ classifications. Organizational change strategies have been differentiated according to previous work of Chin & Benne but one more strategy has been added. Classifications of both the organizational cultures and of the organizational change strategies are based on the same criteria of differentiation: distribution of power in an organization and orientation toward relationships or tasks. For this reason it is possible to formulate hypotheses about the causal relationship between certain types of organizational cultures and certain types of organizational change strategies. Thus, eight hypotheses are formulated in this paper, relating particular change strategies with particular types of organizational culture.

    Yanaoka, Kaichi

    2016-02-01

    This research examined the effects of planning and executive functions on young children's (ages 3-to 5-years) strategies in changing scripts. Young children (N = 77) performed a script task (doll task), three executive function tasks (DCCS, red/blue task, and nine box task), a planning task, and a receptive vocabulary task. In the doll task, young children first enacted a "changing clothes" script, and then faced a situation in which some elements of the script were inappropriate. They needed to enact a script by compensating inappropriate items for the other-script items or by changing to the other script in advance. The results showed that shifting, a factor of executive function, had a positive influence on whether young children could compensate inappropriate items. In addition, planning was also an important factor that helped children to change to the other script in advance. These findings suggest that shifting and planning play different roles in using the two strategies appropriately when young children enact scripts in unexpected situations. PMID:26964369

  15. Strategy changing penalty promotes cooperation in spatial prisoner’s dilemma game

    International Nuclear Information System (INIS)

    Many classical studies suggest that punishment is a useful way to promote cooperation in the well-mixed public goods game, whereas relative evidence in the research of spatial prisoner’s dilemma game is absent. To address this issue, we introduce a mechanism of strategy changing penalty, combining memory and penalty during the update process, into spatial prisoner’s dilemma game. We find that increasing penalty rate or memory length is able to promote the evolution of cooperation monotonously. Compared with traditional version, recorded penalty could facilitate cooperation better. Moreover, through examining the process of evolution, we provide an interpretation for this promotion phenomenon, namely, the effect of promotion can be warranted by an evolution resonance of standard deviation of fitness coefficient. Finally, we validate our results by studying the impact of uncertainty within strategy adoptions on the evolution of cooperation. We hope that our work may shed light on the understanding of the cooperative behavior in the society.

  16. Modeling change in learning strategies throughout higher education: a multi-indicator latent growth perspective.

    Directory of Open Access Journals (Sweden)

    Liesje Coertjens

    Full Text Available The change in learning strategies during higher education is an important topic of research in the Student Approaches to Learning field. Although the studies on this topic are increasingly longitudinal, analyses have continued to rely primarily on traditional statistical methods. The present research is innovative in the way it uses a multi-indicator latent growth analysis in order to more accurately estimate the general and differential development in learning strategy scales. Moreover, the predictive strength of the latent growth models are estimated. The sample consists of one cohort of Flemish University College students, 245 of whom participated in the three measurement waves by filling out the processing and regulation strategies scales of the Inventory of Learning Styles--Short Versions. Independent-samples t-tests revealed that the longitudinal group is a non-random subset of students starting University College. For each scale, a multi-indicator latent growth model is estimated using Mplus 6.1. Results suggest that, on average, during higher education, students persisting in their studies in a non-delayed manner seem to shift towards high-quality learning and away from undirected and surface-oriented learning. Moreover, students from the longitudinal group are found to vary in their initial levels, while, unexpectedly, not in their change over time. Although the growth models fit the data well, significant residual variances in the latent factors remain.

    greater relaxation of extensional strains during the preparatory test, leading to a subsequent increase in compression when the samples were returned to the neutral position prior to our measurement. Thin sections of the notch area help confirm these observations, as a narrow but continuous fracture following grain boundaries is evident in M4 and M2. M5 shows a buildup of extensional strains in the notch tip area due to low loading, though no cracking is evident. These results provide exceptional insight into the physics of fracture propagation under typical real-world conditions. We observe notably different mechanical inter- and intragranular responses to long-term static low loading under either wet or dry conditions, a result which contributes significantly to our ability to evaluate the potential impact of changes in (for example) rainfall distribution, chemistry, and meltwater production on tensile fracture propagation and alpine rock slope stability.

  3. Adapting to climate change in forest based land use systems: A guide to strategy

    Secrett, C.M.

    1996-12-31

    The prospect of climate change and sea level rise as a result of greenhouse gas emissions presents a serious challenge to decision-makers concerned with ensuring sustainable development. This report provides a guide to means of reducing the potential impact of the global warming problem on the forest sector whilst ensuring that more immediate development priorities are met. The most effective response strategy will be one that simultaneously brings both immediate development and longer-term adaptive benefits. This report outlines ways of constructing an adaptive response strategy that can help achieve these ends. The approach is referred to as sustainable adaptation. A prototype methodological framework of the sustainable adaptation approach has been provided with the summary. The first priority of sustainable adaption is to base climate change responses on actions that meet basic ecological and social needs now and in the future. Solutions should necessarily include relieving current development pressures in the tropical forest sector. The key is to couple adaptive responses to climate change with sustainable development solutions to present-day forest use problems. Implementing adaptive land-use policies and management practices which are likely to minimise the adverse impacts of anticipated climate change should meet current sustainable management goals. Implementing sustainable land-use and forestry management practices should meet adaptation goals. This report presents a discussion of the fundamental issues underlying the development of a sustainable adaptation strategy and a prototype methodological framework. The findings are based on case studies conducted in Central America (Costa Rica and Nicaragua); SADCC countries in Africa (Zimbabwe, Botswana, Tanzania); and Asia (Vietnam). 450 refs

Estimates of primary and secondary energy use and CO{sub 2} emissions for 1988 and 2005 are presented, and three strategies are examined in each end-use sector: energy efficiency, fuel switching, and renewable energy measures. For the residential, commercial, transport, industrial, and iron/steel industry sectors, a profile of CO{sub 2} emissions and energy intensity trends is offered, opportunities for CO{sub 2} reduction and measures to reduce CO{sub 2} emissions are described, and the economic and social implications are discussed. Natural gas cogeneration is examined as a technological option for reducing CO{sub 2} emissions and creating important opportunities for the Ontario economy. The role of energy utility reform in CO{sub 2} emissions reduction is assessed in an examination of the key factors needed for the design and implementation of demand side management programs that achieve high participation rates and significant reductions in energy demand. 102 refs., 6 figs., 53 tabs.

  5. Urban Planning and Climate Change: Adaptation and Mitigation Strategies

    Full Text Available Climate change is a current phenomenon: the temperatures rise, rainfall patterns are changing, glaciers melt and the average global sea level is rising. It is expected that these changes will continue and that the extreme weather events, such as floods and droughts, will become more frequent and intense. The impact and vulnerability factors for nature, for the economy and for our health are different, depending on the territorial, social and economic aspects. The current scientific debate is focused on the need to formulate effective policies for adaptation and mitigation to climate change. The city plays an important role in this issue: it emits the most greenhouse gas emissions (more than 60% of the world population currently lives in urban areas and the city is more exposed and vulnerable to the impacts of climate change. Urban planning and territorial governance play a crucial role in this context: the international debate on the sustainability of urban areas is increasing. It’s necessary to adapt the tools of building regulations to increase the quality of energy - environment of the cities.

    Full Text Available Suprapubic cystostomy is commonly performed in patients with neurogenic bladder or bladder outlet obstruction. The most serious complication is bowel injury, which usually occurs during catheter insertion. Bowel perforation during suprapubic catheter exchange is rare. We herein report an extremely rare case of terminal ileal perforation resulting from a change of suprapubic catheter. After insertion of the suprapubic catheter, a feculent material was noted in the terminal ileum. A cystography revealed that the contrast medium passed directly into the terminal ileum and colon. A computed tomographic scan confirmed the presence of a balloon tip in the terminal ileum. Terminal ileum perforation was diagnosed. Emergent laparotomy and loop ileostomy were performed. The patient's recovery was uneventful.

    Few studies of community interventions examine independent effects of investments in: (1) capital (i.e., physical, human and social capital), and (2) management systems (e.g., monitoring and evaluation systems (M&E)) on maternal and child health behavior change. This paper does this in the context of an inter-organizational network. In Nicaragua, international non-governmental organizations (NGOs) and local NGOs formed the NicaSalud Federation. Using Lot Quality Assurance Sampling (LQAS), 14 member organizations took baselines measures of maternal safe motherhood and child health behavior indicators during November 1999 and August 2000, respectively, and final evaluation measures in December 2001. In April 2002, retrospective interviews were conducted with supervisors and managers in the 14 organizations to explore changes made to community health strategies, factors associated with the changes, and impacts they attributed to participating in NicaSalud. Physical capital (density of health huts), human capital (density and variety of paramedical personnel) and social capital (density of health committees) were associated with pregnant women attending antenatal care (ANC) 3+ times, and/or retaining ANC cards. The variety of paramedic personnel was also associated with women making post-partum visits to clinics. Physical capital (density of health huts) and social capital (density of health committees and mothers' clubs) were associated with child diarrhea case management indicators. One safe motherhood indicator (delivery of babies by a clinician) was not associated with intervention strategies. At the management level, NicaSalud's training of members to use LQAS for M&E was associated with the number of strategic and tactical changes they subsequently made to interventions (organizational learning). Organizational learning was related to changes in maternal and child health behaviors of the women (including changes in the proportion using post-partum care). As the

    (1.5 degrees lat-lon) outputs of the JMA-GSM climate general circulation model. Preliminary results are here presented. Two different periods have been analysed. The first period, covering 1979-2002 has been compared with the previously computed ERA-40 climatology of cyclones. Results agree reasonably well with those obtained from ERA-40, providing confidence to the current climate simulation of JMA-GSM. Once validated the model from the perspective of cyclonic climatology under current climate conditions, the same procedure is applied to a scenario period (2075-2099) to investigate possible changes in cyclonic activity linked to climate change.

    Adaptations to resource availability strongly shape patterns of community composition along successional gradients in environmental conditions. In the present study, we examined the extent to which variation in functional composition explains shifts in trait-based functional strategies in young tropical secondary forests during the most dynamic stage of succession (0-20 years). Functional composition of two size classes in 51 secondary forest plots was determined using community-weighted means of seven functional traits, which were intensively measured on 55 woody plant species (n = 875-1,761 individuals). Along the successional gradient in forest structure, there was a significant and consistent shift in functional strategies from resource acquisition to resource conservation. Leaf toughness and adult plant size increased significantly, while net photosynthetic capacity (A(mass)) decreased significantly during succession. Shifts in functional strategies within size classes for A(mass) and wood density also support the hypothesis that changes in functional composition are shaped by environmental conditions along successional gradients. In general, 'hard' functional traits, e.g., A(mass) and leaf toughness, linked to different facets of plant performance exhibited greater sensitivity to successional changes in forest structure than 'soft' traits, such as leaf mass area and leaf dry matter content. Our results also suggested that stochastic processes related to previous land-use history, dispersal limitation, and abiotic factors explained variation in functional composition beyond that attributed to deterministic shifts in functional strategies. Further data on seed dispersal vectors and distance and landscape configuration are needed to improve current mechanistic models of succession in tropical secondary forests. PMID:25990298

    Ignoring irrelevant visual information aids efficient interaction with task environments. We studied how people, after practice, start to ignore the irrelevant aspects of stimuli. For this we focused on how information reduction transfers to rarely practised and novel stimuli. In Experiment 1, we compared competing mathematical models on how people cease to fixate on irrelevant parts of stimuli. Information reduction occurred at the same rate for frequent, infrequent, and novel stimuli. Once acquired with some stimuli, it was applied to all. In Experiment 2, simplification of task processing also occurred in a once-for-all manner when spatial regularities were ruled out so that people could not rely on learning which screen position is irrelevant. Apparently, changes in eye movements were an effect of a once-for-all strategy change rather than a cause of it. Overall, the results suggest that participants incidentally acquired knowledge about regularities in the task material and then decided to voluntarily apply it for efficient task processing. Such decisions should be incorporated into accounts of information reduction and other theories of strategy change in skill acquisition. PMID:25203902

    2014-06-01

    Full Text Available This research article aims to explain the changes of livelihoods strategies in a village in the Northeast region of Thailand after the introduction of rubber as cash crop. Northeast region is considered a new rubber growing area of Thailand, the world’s largest rubber exporter. A village in Udornthani province was selected as a case study for a qualitative research conducted in 2012-2013. In order to get a full understanding of these changes, the research studied livelihood changes in the village over the last 62 years or since the village establishment. We have classified livelihood strategies into three periods, based on the dominant mode of production and livelihoods. The first period was the livelihoods before cash crops, in which people were involved in subsistence mode of production. The second period was marked by the introduction of cash crops and market economy into the village in the early 1960s. During this period, subsistence economy had been transformed into market oriented. Forest lands were changed into cash crop farms, so much that the natural capital lost its balance and became less dependable. The third period, starting in 2001, was the rubber period, the focus of this research. Rubber came to the northeastern region as a result of the promotion of the state. Strong research, development and extension supports that used to work well in the Southern region were applied to promote rubber growing here. However, the adoption of rubber was not without problems. People had to adjust themselves to the capitalist standardized farming practices of rubber. In addition, there was a misbalance of and unequal access to capital assets, particularly financial capital. Within the changing socio-economic context and constraining status of capital assets and access, rural households adopted integrated livelihood strategies, including 1 economic diversification or pluri-activities to reduce risks and increase income 2 maintaining rice

    Full Text Available Abstract Background Forests occur across diverse biomes, each of which shows a specific composition of plant communities associated with the particular climate regimes. Predicted future climate change will have impacts on the vulnerability and productivity of forests; in some regions higher temperatures will extend the growing season and thus improve forest productivity, while changed annual precipitation patterns may show disadvantageous effects in areas, where water availability is restricted. While adaptation of forests to predicted future climate scenarios has been intensively studied, less attention was paid to mitigation strategies such as the introduction of tree species well adapted to changing environmental conditions. Results We simulated the development of managed forest ecosystems in Germany for the time period between 2000 and 2100 under different forest management regimes and climate change scenarios. The management regimes reflect different rotation periods, harvesting intensities and species selection for reforestations. The climate change scenarios were taken from the IPCC's Special Report on Emission Scenarios (SRES. We used the scenarios A1B (rapid and successful economic development and B1 (high level of environmental and social consciousness combined with a globally coherent approach to a more sustainable development. Our results indicate that the effects of different climate change scenarios on the future productivity and species composition of German forests are minor compared to the effects of forest management. Conclusions The inherent natural adaptive capacity of forest ecosystems to changing environmental conditions is limited by the long life time of trees. Planting of adapted species and forest management will reduce the impact of predicted future climate change on forests.

  18. Role of competition in vegetation change: evolutionarily stable strategy analysis as a means for predicting change in vegetation distributions

    Farrior, C.

    2015-12-01

    One of the clearest differences among major vegetation types is allocation to woody biomass. Whether and to what extent plants invest in this long-lived tissue has a major impact on carbon storage and can have important feedbacks to the rising CO2 in the atmosphere. Wood is a multifaceted structure. It can allow plants to escape from ground fires, the pressure of herbivores, and perhaps most importantly competition with other plants for light. Understanding the result of this final pressure requires an incorporation of individual-based interactions among plants. This can be a particularly difficult because of both high computational demands and errors in implementation and understanding of such complex models. We have made progress on both difficulties for understanding allocation to woody biomass among trees in forests. Across gradients in resource availability within forests, we find a significant influence of individual-based competition on dominant plant allocation to woody biomass. In model predictions and observed differences among forests globally major tradeoffs occur in allocation to woody biomass versus allocation to fine roots. This is driven by shifting importance of individual-based competition for light versus shared resources belowground, in particular water and nitrogen. Moving beyond forests to biome boundaries, transitions between grassland, savanna, and forest we see again that competition can play an important role. In these zones of rapid change however, population dynamics is not as simple as a steady-state closed-canopy forest. Disturbance dynamics including response to fire and drought stress are also important pressures on dominant plant strategies. Here I show progress in incorporating disturbance dynamics with individual based competition to predict and understand dominant plant strategies including allocation to woody biomass. Results indicate that the influence of competition varies with disturbance regime. With stochastic disturbance

    Climate change poses major challenges for conservation and management because it alters the area, quality, and spatial distribution of habitat for natural populations. To assess species’ vulnerability to climate change and target ongoing conservation investments, researchers and managers often consider the effects of projected changes in climate and land use on future habitat availability and quality and the uncertainty associated with these projections. Here, we draw on tools from hydrology and climate science to project the impact of climate change on the density of wetlands in the Prairie Pothole Region of the USA, a critical area for breeding waterfowl and other wetland-dependent species. We evaluate the potential for a trade-off in the value of conservation investments under current and future climatic conditions and consider the joint effects of climate and land use. We use an integrated set of hydrological and climatological projections that provide physically based measures of water balance under historical and projected future climatic conditions. In addition, we use historical projections derived from ten general circulation models (GCMs) as a baseline from which to assess climate change impacts, rather than historical climate data. This method isolates the impact of greenhouse gas emissions and ensures that modeling errors are incorporated into the baseline rather than attributed to climate change. Our work shows that, on average, densities of wetlands (here defined as wetland basins holding water) are projected to decline across the U.S. Prairie Pothole Region, but that GCMs differ in both the magnitude and the direction of projected impacts. However, we found little evidence for a shift in the locations expected to provide the highest wetland densities under current vs. projected climatic conditions. This result was robust to the inclusion of projected changes in land use under climate change. We suggest that targeting conservation towards wetland

    2012-01-01

    Full Text Available Rheraya watershed already suffers from the impacts of climate variability and will be further affected by climate change. Severe water shortages and extremely fragile ecological conditions necessitate careful attention to water resources management. The aim of this study is to analyze Rheraya’s future water situation under different scenarios of socio-economic development and climate change until 2100. The Water Evaluation and Planning System model (WEAP has been applied to estimate the current water demands and the increased water demands resulting from climate change. WEAP was calibrated using meteorological and demand observations, then, updated with present-day and future climatic conditions using the Statistical Down-scaling Model with two projections (A2, B2 of the Intergovernmental Panel on Climate Change. Those projections show an increase in temperature of about 2–3 °C and a reduction in precipitation of 40–60% with respect to baseline. The results show that the pressure on Rheraya’s water resources will increase, leading to greater competition for surface water, and that domestic, tourist, livestock and agricultural demands will not be met by the year 2100. The Results also demonstrate that the assessments of adaptation strategies proposed by decision makers are effective but not sustainable for the watershed.

  14. Vulnerability of Worldwide Pastoralism to Global Changes and Interdisciplinary Strategies for Sustainable Pastoralism

    Directory of Open Access Journals (Sweden)

    Xiaoyan Li

    2011-06-01

    Full Text Available Ten case studies from seven major pastoral regions across six continents were studied in this paper by conceptualizing three factors (agro-ecosystem resilience, livelihood options, and institution capacity as the axes of a three-dimensional vulnerability framework. This analysis highlights the vulnerability of agriculture-based livelihood systems to global changes and helps identify what institutions have the potential to mobilize effective relief in different pastoral regions. In terms of results, this vulnerability assessment shows that the vulnerability of pastoralism was very different in all the cases across the globe. As such, a further analysis, based on the pressure-state-response (PSR model was undertaken to enhance our understanding of the ways that global changes put pressures on pastoral livelihoods worldwide. From this we conclude that climate change and climate variability are driving fragile pastoral ecosystems into more vulnerable conditions. Socioeconomic factors, such as changes in land tenure, agriculture, sedentarization, and institutions are fracturing large-scale pastoral ecosystems into spatially isolated systems. The implications of this analysis are that professionals, practitioners, and policy makers should jointly develop a coupled human and natural systems approach that focuses on enhancing the resilience of pastoral communities and their practices. This requires institutional developments to support asset building and good governance to enhance adaptive capability. In addition, pastoralists' adaptation strategies to global change need to be supported by public awareness and improved by institutional decisions at different scales and dimensions.

    Kikoyo, Duncan A.; Nobert, Joel

    2016-06-01

    Globally, various climatic studies have estimated a reduction of crop yields due to changes in surface temperature and precipitation especially for the developing countries which is heavily dependent on agriculture and lacks resources to counter the negative effects of climate change. Uganda's economy and the wellbeing of its populace depend on rain-fed agriculture which is susceptible to climate change. This study quantified the impacts of climate change and variability in Uganda and how coping strategies can enhance crop production against climate change and/or variability. The study used statistical methods to establish various climate change and variability indicators across the country, and uses the FAO AquaCrop model to simulate yields under possible future climate scenarios with and without adaptation strategies. Maize, the most widely grown crop was used for the study. Meteorological, soil and crop data were collected for various districts representing the maize growing ecological zones in the country. Based on this study, it was found that temperatures have increased by up to 1 °C across much of Uganda since the 1970s, with rates of warming around 0.3 °C per decade across the country. High altitude, low rainfall regions experience the highest level of warming, with over 0.5 °C/decade recorded in Kasese. Rainfall is variable and does not follow a specific significant increasing or decreasing trend. For both future climate scenarios, Maize yields will reduce in excess of 4.7% for the fast warming-low rainfall climates but increase on average by 3.5% for slow warming-high rainfall regions, by 2050. Improved soil fertility can improve yields by over 50% while mulching and use of surface water management practices improve yields by single digit percentages. The use of fertilizer application needs to go hand in hand with other water management strategies since more yields as a result of the improved soil fertility leads to increased water stress, especially

Therefore, top management should be deal with this problem using effective change management strategies and processes. In this paper, we discuss the successful change management strategies and processes in literature. A case study of MADAR has been presented to discover the strategies and processes used for the successful enterprise system.

  19. Hydropower, an integral part of Canada's climate change strategy

    International Nuclear Information System (INIS)

    The development and implementation of a climate change policy could be among the most far-reaching environmental initiatives ever embarked upon in Canada and abroad. If Canada is to stabilize or reduce its Greenhouse Gas (GHG) emissions over the long term, a significant adjustment to Canadian industry will be required as we move away from fossil fuel-intensive and GHG producing activities. Future hydroelectric projects provide Canada with a unique opportunity to significantly reduce the costs associated with stabilizing its GHG emissions. In addition, the energy storage and dispatchability associated with hydropower can support development of other low emitting renewable resources such as wind and solar. This document discusses the potential role of hydropower as a tool to reduce emissions, recommends action to reduce barriers facing hydropower and comments on some of the policy tools available to manage Canada's GHG emissions.

    2005-01-01

    One of the historical challenges in the healthcare system has been the identification and collection of meaningful data to measure an organization's progress towards the achievement of its strategic goals and the concurrent alignment of internal operating practices with this strategy. Over the last 18 months the Toronto East General Hospital (TEGH) has adopted a strategic management system and organizing framework that has led to a metric-based strategic plan. It has allowed for formal and measurable linkages across a full range of internal business processes, from the annual operating plan to resource allocation decisions, to the balanced scorecard and individual performance evaluations. The Strategic Management System (SMS) aligns organizational planning and performance measurement, facilitates an appropriate balance between organizational priorities and resolving "local" problems, and encourages behaviours that are consistent with the values upon which the organization is built. The TEGH Accountability Framework serves as the foundation for the entire system. A key tool of the system is the rolling three-year strategic plan for the organization that sets out specific annual improvement targets on a number of key strategic measures. Individual program/department plans with corresponding measures ensure that the entire organization is moving forward strategically. Each year, all plans are reviewed, with course adjustments made to reflect changes in the hospital's environment and with re-calibration of performance targets for the next three years to ensure continued improvement and organizational progress. This system has been used through one annual business cycle. Results from the past year show measurable success. The hospital has improved on 12 of the 15 strategic plan metrics, including achieving the targeted 1% operating surplus while operating in an environment of tremendous change and uncertainty. This article describes the strategic management system used

  4. What Role Should Black Carbon Play in Climate Change Mitigation Strategies?

    Science.gov (United States)

    Deangelo, B. J.

    2006-12-01

    The uncertainties of the black carbon-climate linkage remain large with regard to emissions quantification, temporal and regional atmospheric concentrations, and net radiative and other climatic effects. Given these physical uncertainties plus other economic and emission control considerations, what is the appropriate role for BC and organic carbon in any climate change mitigation strategy? If the climate effects of BC are considered `large enough' (a judgment call) to warrant emission controls to mitigate climate change, additional considerations are necessary to determine how best to do this. First, BC cannot be singly targeted, as BC is co-emitted with OC in various ratios depending on fuel type and combustion technology. The climate effects of any control strategy will depend on the net BC and OC, plus possible greenhouse gas, co-effects, which in turn will vary by specific emission source, sector and region. Second, the extent to which air quality policies (primarily targeting particulate matter for health concerns) control BC and OC can determine whether additional emission mitigation is necessary, or if additional mitigation is best pursued within the context of air quality policies, rather than being introduced into the climate area. In the U.S., on-road and off-road diesel vehicles are the largest sources of BC, but these emissions are expected to decline substantially over the next few decades due to recently issued U.S. EPA standards. Third is the issue of costs of BC reductions relative to the costs of other mitigation strategies. Results will be presented on 1) near-term (out to 2020) emission projections for the U.S. taking into account recent air quality regulations; 2) emerging work from the Energy Modeling Forum Black Carbon Subgroup on global and regional projections by region and sector, and mitigation scenarios; and 3) the costs of potential BC mitigation options for the U.S.

    Full Text Available In Indonesia, the climate change and the global warming like changes in the pattern and distribution of the rainfall give impacts on agricultural production at large, especially in the food crops. These also cause droughts, floods, landslides, forest fires, rising temperatures in urban areas, and rising sea levels. The above impacts are felt by the farmers because those can lead to a decrease in production even the crop failure. This research aims to develop an empowerment strategy of the food crop farmers in anticipating the climate change in Central Java. The data used is the primary data obtained through in-depth interviews with key-person and the Focus Group Discussion (FGD. The Analysis Hierarchy Process (AHP is conducted to determine the program priorities and strate gies. The result of research shows that anticipating the climate change should be synergistically conducted in four aspects: human resources, technology, institutional and production, by involving various groups in the society. Various groups can be grouped into academics, businessmen / private sectors, government and community of food crop farmers / society.

    The 2007 Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) concludes: "Warming in the climate system is unequivocal." Without the contribution of Physics to climate science over many decades, such a statement would not have been possible. Experimental physics enables us to read climate archives such as polar ice cores and so provides the context for the current changes. For example, today the concentration of CO2 in the atmosphere, the second most important greenhouse gas, is 28% higher than any time during the last 800,000 years. Classical fluid mechanics and numerical mathematics are the basis of climate models from which estimates of future climate change are obtained. But major instabilities and surprises in the Earth System are still unknown. These are also to be considered when the climatic consequences of proposals for geo-engineering are estimated. Only Physics will permit us to further improve our understanding in order to provide the foundation for policy decisions facing the...

    2010-07-01

    This book expresses the French State's view on the way to deal with the issue of climate change adaptation. After having recalled the ineluctability of some observed changes, the actors involved in this adaptation, and some guideline principles to implement adaptation, a first chapter describes the context: international mobilization, climate data evolution, definition of new criteria and critical thresholds, relationship between adaptation, alleviation and sustainable development, tensions between long and short terms. It discusses the objectives: public security and health, alleviation of inequalities with respect to risks, cost reduction, natural heritage preservation. Nine strategic axes are then identified: to develop knowledge, to strengthen the survey system, to inform, to educate and to make all actors aware, to promote a territory-based approach, to finance adaptation actions, to use regulatory and law instruments, to support voluntary approaches and the dialogue with private actors, to take the overseas peculiarity into account, and to contribute to international exchanges. The next chapters are respectively dealing with transverse approaches (water, risk prevention, health, and biodiversity), sector-based insights (agriculture, energy and industry, transports, building and housing, tourism, banks and insurance companies), medium-based approach (cities, littoral and seas, mountain, forest). The last part deals with the implementation issue

    1994-01-01

    A participatory strategy to increase face washing was designed and tested in central Tanzania. Changing children's face-washing behaviour is postulated to be important in preventing the transmission of eye disease, particularly blinding trachoma. The strategy used non-formal adult education techniques at neighbourhood level meetings to build a community consensus to keep children's faces clean for the prevention of eye disease. Men, women, schoolchildren, traditional healers and village social groups participated in the intervention. The strategy was evaluated by observing changes in numbers of clean faces of a sample of preschool children in the village. Clean faces increased from 9% to 33% over the course of a year. Factors which were related to sustained change in children's clean faces included distance to water, age of the child, and presence of a corrugated metal roof. Owning cattle was associated with lack of sustainable change in this population. PMID:7992324

  20. A strategy to correct for intrafraction target translation in conformal prostate radiotherapy: Simulation results

    International Nuclear Information System (INIS)

    A strategy is proposed in which intrafraction internal target translation is corrected for by repositioning the multileaf collimator position aperture to conform to the new target pose in the beam projection, and the beam monitor units are adjusted to account for the change in the geometric relationship between the target and the beam. The purpose of this study was to investigate the dosimetric stability of the prostate and critical structures in the presence of internal target translation using the dynamic compensation strategy. Twenty-five previously treated prostate cancer patients were replanned using a four-field conformal technique to deliver 72 Gy to 95% of the planning target volume (PTV). Internal translation was introduced by displacing the prostate PTV (no rotation or deformation was considered). Thirty-six randomly selected isotropic displacements of magnitude 0.5, 1.0, 1.5 and 2.0 cm were sampled for each patient, for a total of 3600 errors. Due to their anatomic relation to the prostate, the rectum and bladder contours were also moved with the same magnitude and direction as the prostate. The dynamic compensation strategy was used to correct each of these errors by conforming the beam apertures to the new target pose and adjusting the monitor units using inverse-square and off-axis factor corrections. The dynamic compensation strategy plans were then compared to the original treatment plans via dose-volume histogram (DVH) analysis. Changes of more than 5% of the prescription dose (3.6 Gy) were deemed clinically significant. Compared to the original treatment plans, the dynamic compensation strategy produced small discrepancies in isodose distributions and DVH analyses for all structures considered apart from the femoral heads. These differences increased with the magnitude of the internal motion. Coverage of the PTV was excellent: D5, D95, and Dmean were not increased or decreased by more than 5% of the prescription dose for any of the 3600 simulated

    Full Text Available This study sought to investigate navigational strategies across the life span, by testing 8-year old children to 80-year old healthy older adults on the 4 on 8 virtual maze (4/8VM. The 4/8VM was previously developed to assess spontaneous navigational strategies, i.e. hippocampal-dependent spatial strategies (navigation by memorizing relationships between landmarks versus caudate nucleus-dependent response strategies (memorizing a series of left and right turns from a given starting position. With the 4/8VM, we previously demonstrated greater fMRI activity and grey matter in the hippocampus of spatial learners relative to response learners. A sample of 599 healthy participants was tested in the current study. Results showed that 84.4% of children, 46.3% of young adults, and 39.3% of older adults spontaneously used spatial strategies (p < 0.0001. Our results suggest that while children predominantly use spatial strategies, the proportion of participants using spatial strategies decreases across the life span, in favor of response strategies. Factors promoting response strategies include repetition, reward and stress. Since response strategies can result from successful repetition of a behavioral pattern, we propose that the increase in response strategies is a biological adaptive mechanism that allows for the automatization of behavior such as walking in order to free up hippocampal-dependent resources. However, the downside of this shift from spatial to response strategies occurs if people stop building novel relationships, which occurs with repetition and routine, and thereby stop stimulating their hippocampus. Reduced fMRI activity and grey matter in the hippocampus were shown to correlate with cognitive deficits in normal aging. Therefore, these results have important implications regarding factors involved in healthy and successful aging.

    2014-05-01

    The connection of climate change and air pollution is becoming more relevant in the process of policy making and implementation of emission control strategies because of resulting co-benefits and trade-offs. Some sectors, such as fossil fuel combustion, are sources of both pollutants (NOx and PM) as well as greenhouse gas (CO2). Additionally, the use of wood burning as biofuel to reduce climate impact may in fact deteriorate air quality. Furthermore, several air pollutants are important radiative forcers and regulating their emissions impacts on climate. It is evident that both problems need to be undertaken with a common strategy and the existence of cross-policy with co-benefits may encourage their implementation. The LIMITS FP7 project (http://www.feem-project.net/limits/index.html) was designed with the main goal of assessing strategies for reduction of GHG emissions so that the 2°C target can be achieved. The work developed focus on the evaluation of the implementation of strategies analysing several aspects of different scenarios, namely: the feasibility of low carbon scenarios in terms of available technologies and infrastructure, the required financial mechanisms, and also the co-benefits regarding energy security, economic development and air pollution. For the latter, five integrated assessment models (IAMs) provided greenhouse gases and pollutant emission values for several scenarios. These were based on air pollution scenarios defined according to stringency and implementation of future global legislation. They which were also combined with 2 climate policy scenarios (no climate policy and 2.8 W/m2 target). The former are mostly focused on non-climate policies and technical control measures for emissions of air pollutants, such as PM2.5, NOx and SO2, with their emission factors harmonized between the IAMs. With the global air quality source-receptor model TM5-FASST the impact of the resulting emissions was analysed and the co-benefits of combined

    A remote sensing based land cover change assessment methodology is presented and applied to a case study of the Oil Sands Mining Development in Athabasca, Alta., Canada. The primary impact was assessed using an information extraction method applied to two LANDSAT scenes. The analysis based on derived land cover maps shows a decrease of natural vegetation in the study area (715,094 ha) for 2001 approximately -8.64% relative to 1992. Secondary assessment based on a key resources indicator (KRI), calculated using normalized difference vegetation index (NDVI measurements acquired by NOAA-AVHRR satellites), air temperature and global radiation was performed for a time period from 1990 to 2002. KRI trend analysis indicates a slightly decreasing trend in vegetation greenness in close proximity to the mining development. A good agreement between the time series of inter-annual variations in NDVI and air temperature is observed increasing the confidence of NDVI as an indicator for assessing vegetation productivity and its sensitivity to changes in local conditions.

    2016-06-01

    Genomics is an ever increasing aspect of nursing practice, with focus being directed towards improving health. The authors present an implementation strategy for the incorporation of genomics into nursing practice within the UK, based on three behaviour change theories and the identification of individuals who are likely to provide support for change. Individuals identified as Opinion Leaders and Adopters of genomics illustrate how changes in behaviour might occur among the nursing profession. The core philosophy of the strategy is that genomic nurse Adopters and Opinion Leaders who have direct interaction with their peers in practice will be best placed to highlight the importance of genomics within the nursing role. The strategy discussed in this paper provides scope for continued nursing education and development of genomics within nursing practice on a larger scale. The recommendations might be of particular relevance for senior staff and management. PMID:27241441

    This article asks through what processes and for which interests the emerging Vietnamese climate change strategy is being designed, and if, ultimately, it is likely or not to be effective in the face of the looming threat. Through a review of an emerging body of literature and field observations, the paper finds the strategy partial and problematic in several ways. Its technocratic process prevents a pluralist representation of interests, obfuscating and perpetuating sectorial ones, at the expense of a more transparent and democratic resource allocation. The strategy therefore reflects and reinforces existing power relations in both politics and production. It feeds into a business-as-usual complacency, protecting national and international interests vested in unchallenged continuity, even when considering post-carbon technological fixes, which largely serve to expand capital accumulation opportunities. The article concludes that the national climate change strategy provides an illusion of intervention and security, but largely fails to identify and mitigate the underlying causes of climate change, or to lay the ground for a robust mid- and long-term adaptation strategy that can cope with yet unknown levels of climatic and other structural changes.

    We study the time variations of the cycles of 20 active stars based on decades-long photometric or spectroscopic observations. A method of time-frequency analysis, as discussed in a companion paper, is applied to the data. Fifteen stars definitely show multiple cycles; the records of the rest are too short to verify a timescale for a second cycle. The cycles typically show systematic changes. For three stars, we found two cycles in each of them that are not harmonics, and which vary in parallel, indicating that a common physical mechanism arising from a dynamo construct. The positive relation between the rotational and cycle periods is confirmed for the inhomogeneous set of active stars. Stellar activity cycles are generally multiple and variable.

  15. Remediation strategies for contaminated territories resulting from Chernobyl accident. Final report

    International Nuclear Information System (INIS)

    The present report realizes a settlement specific approach to derive remediation strategies and generalizes the results to the whole affected area. The ultimate aim of the study is to prepare possible investment projects on remediation activities in the contaminated territories. Its current aim was to identify the areas and the remedial actions that should be primarily supported and their corresponding cost. The present report starts with an outline of the methodology of deriving remediation strategies, a description of data for 70 representative settlements and of parameters of the remedial actions considered, and a classification of the contaminated territory according to radiological criteria. After summarising aspects of the contamination situation and applications of remedial actions in the past, dose calculations and derived remediation strategies for the representative settlements are described. These are generalized to the total contaminated territory. Within the contaminated territory private produce is of main importance for the radionuclide intake. At the end of the report, radiological aspects of the produce of collective farms are described. (orig.)

    Even if we succeed in achieving the EU target of reducing global warming to 2 C, it will be absolutely essential to adapt to changing climatic conditions. The greenhouse gases currently present in the atmosphere will influence the climate in coming decades. The day on which it is quite clear which climatic scenario prevails, so that it is possible to model all relevant processes down to regional level, will be the day on which it is too late to adapt to the actual scenario. Our endeavours to adapt to climate change do not mean, however, that we can neglect to take measures in order to reduce the output of greenhouse gases. It is important to remember that on their own, neither adaptation nor mitigation can prevent the grave impacts resulting from climate change. In fact, they complement each other meaningfully thus helping to alleviate the risks of climate change. On 17th December 2008 the German Federal Cabinet adopted the DAS (German Strategy for the Adaptation to Climate Change), (Bundesregierung 2008). The DAS has created the framework for adapting to the consequences of climate change in Germany. First and fore-most, the DAS contributes its guidelines at Federal level, to provide a guideline for agents at other levels. The Strategy lays the foundation for a medium-term process. In conjunction with the individual Federal States and other groups representing various sectors of society, the Strategy provides a step-by-step assessment of the risks of climate change. Furthermore, it states the potential requirements for action, and defines the appropriate goals and potential adaptation measures to be developed and implemented in this process. In due course, the Federal Environment Agency (UBA) will design a comprehensive set of tools to support and advance the DAS. An integral part of this will be the Special Information System 'Adaptation' (FISKA) and an Indicator System to aid adaptation. The latter is one of the key tasks identified for the DAS. As far

    The Polish Country Study Project was initiated in 1992 as a result of the US Country Study Initiative whose objective was to grant the countries -- signatories of the United Nations` Framework Convention on Climate Change -- assistance that will allow them to fulfill their obligations in terms of greenhouse gases (GHG`s) inventory, preparation of strategies for the reduction of their emission, and adapting their economies to the changed climatic conditions. In February 1993, in reply to the offer from the United States Government, the Polish Government expressed interest in participation in this program. The Study proposal, prepared by the Ministry of Environmental Protection, Natural Resources and Forestry was presented to the US partner. The program proposal assumed implementation of sixteen elements of the study, encompassing elaboration of scenarios for the strategy of mission reduction in energy sector, industry, municipal management, road transport, forestry, and agriculture, as well as adaptations to be introduced in agriculture, forestry, water management, and coastal management. The entire concept was incorporated in macroeconomic strategy scenarios. A complementary element was the elaboration of a proposal for economic and legal instruments to implement the proposed strategies. An additional element was proposed, namely the preparation of a scenario of adapting the society to the expected climate changes.

    Many past educational initiatives focused on global climate change have foundered on public skepticism and disbelief. Some key reasons for these past failures can be drawn directly from recognized best practices in STEM education - specifically, the necessity to help learners connect new knowledge with their own experiences and perspectives, and the need to create linkages with issues or concerns that are both important for and relevant to the audiences to be educated. The Coastal Areas Climate Change Education (CACCE) partnership has sought to follow these tenets as guiding principles in identifying critical audiences and developing new strategies for educating the public living in the low-lying coastal areas of Florida and the Caribbean on the realities, risks, and adaptation and mitigation strategies for dealing with the regional impacts of global climate change. CACCE is currently focused on three key learner audiences: a) The formal education spectrum, targeting K-12 curricula through middle school marine science courses, and student and educator audiences through coursework and participatory research strategies engaging participants in a range of climate-related investigations. b) Informal science educators and outlets, in particular aquaria and nature centers, as an avenue toward K-12 teacher professional development as well as for public education. c) Regional planning, regulatory and business professionals focused on the built environment along the coasts, many of whom require continuing education to maintain licensing and/or other professional certifications. Our current activities are focused on bringing together an effective set of educational, public- and private-sector partners to target the varied needs of these audiences in Florida and the U.S. Caribbean, and tailoring an educational plan aimed at these stakeholder audiences that starts with the regionally and topically relevant impacts of climate change, and strategies for effective adaptation and

    Science.gov (United States)

    Oh, Phil Seok

    Collaborative action research was undertaken over two years between a Korean science teacher and science education researchers at the University of Iowa. For the purpose of realizing science learning as envisioned by constructivist principles, Group-Investigations were implemented three or five times per project year. In addition, the second year project enacted Peer Assessments among students. Student perceptions of their science classrooms, as measured by the Constructivist Learning Environment Survey (CLES), provided evidence that the collaborative action research was successful in creating constructivist learning environments. Student attitudes toward science lessons, as examined by the Enjoyment of Science Lessons Scale (ESLS), indicated that the action research also contributed to developing more positive attitudes of students about science learning. Discourse analysis was conducted on video-recordings of in-class presentations and discussions. The results indicated that students in science classrooms which were moving toward constructivist learning environments engaged in such discursive practices as: (1) Communicating their inquiries to others, (2) Seeking and providing information through dialogues, and (3) Negotiating conflicts in their knowledge and beliefs. Based on these practices, science learning was viewed as the process of constructing knowledge and understanding of science as well as the process of engaging in scientific inquiry and discourse. The teacher's discursive practices included: (1) Wrapping up student presentations, (2) Addressing misconceptions, (3) Answering student queries, (4) Coaching, (5) Assessing and advising, (6) Guiding students discursively into new knowledge, and (7) Scaffolding. Science teaching was defined as situated acts of the teacher to facilitate the learning process. In particular, when the classrooms became more constructivist, the teacher intervened more frequently and carefully in student activities to fulfill a

    Full Text Available Offering a case study of coastal Bangladesh, this study examines the adaptation of agriculturalists to degrading environmental conditions likely to be caused or exacerbated under global climate change. It examines four central components: (1 the rate of self-reported adoption of adaptive mechanisms (coping strategies as a result of changes in climate; (2 ranking the potential coping strategies based on their perceived importance to agricultural enterprises; (3 identification the socio-economic factors associated with adoption of coping strategies, and (4 ranking potential constraints to adoption of coping strategies based on farmers’ reporting on the degree to which they face these constraints. As a preliminary matter, this paper also reports on the perceptions of farmers in the study about their experiences with climatic change. The research area is comprised of three villages in the coastal region (Sathkhira district, a geographic region which climate change literature has highlighted as prone to accelerated degradation. One-hundred (100 farmers participated in the project’s survey, from which the data was used to calculate weighted indexes for rankings and to perform logistic regression. The rankings, model results, and descriptive statistics, are reported here. Results showed that a majority of the farmers self-identified as having engaged in adaptive behavior. Out of 14 adaptation strategies, irrigation ranked first among farm adaptive measures, while crop insurance has ranked as least utilized. The logit model explained that out of eight factors surveyed, age, education, family size, farm size, family income, and involvement in cooperatives were significantly related to self-reported adaptation. Despite different support and technological interventions being available, lack of available water, shortage of cultivable land, and unpredictable weather ranked highest as the respondent group’s constraints to coping with environmental

    Full Text Available Climate change puts pressure on existing health vulnerabilities through higher frequency of extreme weather events, changes in disease vector distribution or exacerbated air pollution. Climate change adaptation policies may hold potential to reduce societal inequities. We assessed the role of public health and social justice in European climate change adaptation using a three-fold approach: a document analysis, a critical discourse analysis of a subgroup of strategies, and a ranking of strategies against our social justice framework. The ranking approach favored planning that includes various adaptation types, social issues and infrastructure changes. Themes on values identified in the five subgroup documents showed that risks are perceived as contradictory, technology is viewed as savior, responsibilities need to be negotiated, and social justice is advocated by only a few countries. Of 21 strategy documents assessed overall, those from Austria, England and Sweden received the highest scores in the ranking. Our qualitative assessment showed that in European adaptation planning, progress could still be made through community involvement into adaptation decisions, consistent consideration of social and demographic determinants, and a stronger link between infrastructural adaptation and the health sector. Overall, a social justice framework can serve as an evaluation guideline for adaptation policy documents.

  2. Farmers' Perceptions of Climate Change and Agricultural Adaptation Strategies in Rural Sahel

    2009-05-01

    Farmers in the Sahel have always been facing climatic variability at intra- and inter-annual and decadal time scales. While coping and adaptation strategies have traditionally included crop diversification, mobility, livelihood diversification, and migration, singling out climate as a direct driver of changes is not so simple. Using focus group interviews and a household survey, this study analyzes the perceptions of climate change and the strategies for coping and adaptation by sedentary farmers in the savanna zone of central Senegal. Households are aware of climate variability and identify wind and occasional excess rainfall as the most destructive climate factors. Households attribute poor livestock health, reduced crop yields and a range of other problems to climate factors, especially wind. However, when questions on land use and livelihood change are not asked directly in a climate context, households and groups assign economic, political, and social rather than climate factors as the main reasons for change. It is concluded that the communities studied have a high awareness of climate issues, but climatic narratives are likely to influence responses when questions mention climate. Change in land use and livelihood strategies is driven by adaptation to a range of factors of which climate appears not to be the most important. Implications for policy-making on agricultural and economic development will be to focus on providing flexible options rather than specific solutions to uncertain climate.

    Full Text Available In sub-Saharan Africa, knowledge on adaptation strategies to climate variability and change are scattered and fragmented due to lack of standpoints adaptation framework. This paper intends to analyse differences in adaptation strategies across agro-ecological zones, and finding out factors dictating adaptation to climate variability and change to smallholder farmers. The paper is based on documentary review methodology in which journals and books on adaptation were used as the main sources of information. The collected information were analysed by using content analysis. This paper found that smallholder farmers use a variety of practices to adapt to climate variability and change. These practices include: crop management, livestock management, diversification of livelihood strategies and land use management. Availability of extension services, climate change information and membership to social networks were among the factors identified dictating smallholder farmers adaptation to climate variability and change. The paper recommends to the Government of sub-Saharan Africa and development partners to come up with adaptation framework that takes into consideration differences in geographical location. They are needed also to provide enabling conditions to smallholder farmers through strengthening farmers’ supportive services to enhance their adaptive capacities.

    In the past, identifying anthropogenic influences on climate change, scenario analyses and issues of climate change mitigation were predominant approaches in climate change research (IPCC 2007). Currently, for instance in Germany, climate impact research on regional level comes to the forefront of research and policy making. Climate change has become an important topic on the agenda of politicians, administration and planning. In order to counteract the (unavoidable) climate change and its impacts it is necessary to develop adaptation strategies. At present, such strategies and guidelines are formulated on international, supranational and national level. The initial point was the United Nations Framework Convention on Climate Change in 1992 where the contracting states obligated themselves to develop national (and regional) programmes for adaptation. In 2007 the European Commission published its Green Paper called Adaptation to Climate Change in Europe. The paper states that adaptation efforts have to be intensified at different (spatial) levels (local, regional, national, and so forth). Furthermore, coordinating these efforts is of high importance. With the recent agreement on the German Adaptation Strategy to Climate Change (DAS 2008) in December 2008, federal government tries to accomplish this task. The German strategy mainly focuses on two elements: decreasing vulnerability and increasing adaptability. While the above mentioned strategies have presented information and policies concerning climate change and adaptation on international, supranational and national level, such documents dońt yet exist on regional level. However, because of their close link to the local level the regions are of high importance for adaptation strategies. Therefore, the Leibniz-Institute of Ecological and Regional Development developed a transdisciplinary project to formulate and implement the so-called Integrated Regional Climate Adaptation Programme (IRCAP) for the Model Region

    Most power quality problems in distribution systems are related to voltage sags. Therefore, different solutions have been examined to compensate these sags to avoid production losses at sensitive loads. Dynamic voltage restorers (DVRs) have been proposed to provide higher power quality. Currently......, a system wide integration of DVRs is hampered because of their high cost, in particular, due to the expensive DC-link energy storage devices. The cost of these DC-link capacitors remains high because the DVR requires a minimum DC-link voltage to be able to operate and to compensate a sag. As a...... result, only a small fraction of the energy stored in the DC-link capacitor is used, which makes it impractical for DVRs to compensate relatively long voltage sags. Present control strategies are only able to minimize the distortions at the load or to allow a better utilization of the storage system by...

  10. A new islanding detection technique for multiple mini hydro based on rate of change of reactive power and load connecting strategy

    International Nuclear Information System (INIS)

    Highlights: • The requirement of DG interconnection with existing power system is discussed. • Various islanding detection techniques are discussed with their merits and demerits. • New islanding detection strategy is proposed for multiple mini hydro type DGs. • The proposed strategy is based on dq/dt and load connecting strategy. • The effectiveness of strategy is verified on various other cases. - Abstract: The interconnection of distributed generation (DG) into distribution networks is undergoing a rapid global expansion. It enhances the system’s reliability, while simultaneously reduces pollution problems related to the generation of electrical power. To fully utilize the benefits of DGs, certain technical issues need to be addressed. One of the most important issues in this context is islanding detection. This paper presents a new islanding detection technique that is suitable for multiple mini-hydro type DG units. The proposed strategy is based on the rate of change of reactive power and load connecting strategy to detect islanding within the system. For a large power mismatch, islanding is detected by rate of change of reactive power only. However, for a close power mismatch, the rate of change of reactive power initiates a load connecting strategy, which in turn alters the load on the distribution network. This load variation in the distribution network causes a variation in the rate of change of reactive power, which is utilized to distinguish islanding and other events. The simulation results show that the proposed strategy is effective in detecting islanding occurrence in a distribution network

  11. Adaptation strategies for health impacts of climate change in Western Australia: Application of a Health Impact Assessment framework

    International Nuclear Information System (INIS)

    Climate change is one of the greatest challenges facing the globe and there is substantial evidence that this will result in a number of health impacts, regardless of the level of greenhouse gas mitigation. It is therefore apparent that a combined approach of mitigation and adaptation will be required to protect public health. While the importance of mitigation is recognised, this project focused on the role of adaptation strategies in addressing the potential health impacts of climate change. The nature and magnitude of these health impacts will be determined by a number of parameters that are dependent upon the location. Firstly, climate change will vary between regions. Secondly, the characteristics of each region in terms of population and the ability to adapt to changes will greatly influence the extent of the health impacts that are experienced now and into the future. Effective adaptation measures therefore need to be developed with these differences in mind. A Health Impact Assessment (HIA) framework was used to consider the implications of climate change on the health of the population of Western Australia (WA) and to develop a range of adaptive responses suited to WA. A broad range of stakeholders participated in the HIA process, providing informed input into developing an understanding of the potential health impacts and potential adaptation strategies from a diverse sector perspective. Potential health impacts were identified in relation to climate change predictions in WA in the year 2030. The risk associated with each of these impacts was assessed using a qualitative process that considered the consequences and the likelihood of the health impact occurring. Adaptations were then developed which could be used to mitigate the identified health impacts and provide responses which could be used by Government for future decision making. The periodic application of a HIA framework is seen as an ideal tool to develop appropriate adaptation strategies to

    Full Text Available Nowadays, Internet plays a major role in people's lives. It is usually used for entertainment, as a source of information, and also for electronic commerce. Electronic commerce (e-commerce is gradually replacing traditional shopping, especially in the past years. It is a quick and easy form of marketing, which provides convenience for the customers, and, therefore, more and more users are using this form of shopping on the Internet. E-commerce also provides new opportunities for companies, which force them to begin dealing with the Internet. Many customers who are shopping on the Internet look for the best product or service close to their home. Most of the space in the search results in Google is occupied by local results. If a company offers some goods or services and they do not show up on the local search results, the company may be losing a lot of profits from these potential customers. That is why companies have to focus on best ranking in the local search results. In this article, we try to experimentally determine which factors affect ranking in Google search. Of course, it is necessary to quantify the impact of these factors. To select these factors and to determine their impact, we use exact methods of mathematical statistics, hypothesis testing, correlation, and regression analysis. Confirmation and quantification of the impact of some qualitative and quantitative characteristics of the company can be used to formulate recommendations for improving corporate strategy in acquiring new customers.

    Full Text Available Abstract Background Greenhouse gas (GHG mitigation policies can provide ancillary benefits in terms of short-term improvements in air quality and associated health benefits. Several studies have analyzed the ancillary impacts of GHG policies for a variety of locations, pollutants, and policies. In this paper we review the existing evidence on ancillary health benefits relating to air pollution from various GHG strategies and provide a framework for such analysis. Methods We evaluate techniques used in different stages of such research for estimation of: (1 changes in air pollutant concentrations; (2 avoided adverse health endpoints; and (3 economic valuation of health consequences. The limitations and merits of various methods are examined. Finally, we conclude with recommendations for ancillary benefits analysis and related research gaps in the relevant disciplines. Results We found that to date most assessments have focused their analysis more heavily on one aspect of the framework (e.g., economic analysis. While a wide range of methods was applied to various policies and regions, results from multiple studies provide strong evidence that the short-term public health and economic benefits of ancillary benefits related to GHG mitigation strategies are substantial. Further, results of these analyses are likely to be underestimates because there are a number of important unquantified health and economic endpoints. Conclusion Remaining challenges include integrating the understanding of the relative toxicity of particulate matter by components or sources, developing better estimates of public health and environmental impacts on selected sub-populations, and devising new methods for evaluating heretofore unquantified and non-monetized benefits.

    International Nuclear Information System (INIS)

    The causes and effects of climate change are just as varied as the proposed solutions and approaches for dealing with the problem. Given the global character of climate change, comprehensive global cooperation is called for that leads to effective and appropriate international action in accordance with the respective responsibilities. These will inevitably differ depending on the capabilities and the social and economic situations of the respective actors. The contributions in this book present a variety of ideas, approaches and tools regarding the adaptation to climate change in specific countries and regions. In addition to examining (existing) legal instruments, they also focus on the implementation of economic instruments and planning tools, as well as their (further) development. Rather than simply discussing strategies to counteract climate change by reducing emissions, the authors also search for ways of actively adapting to climate change.

    While reaching consensus on future plans to address current global health challenges is far from easy, there is broad agreement that reductionist approaches that suggest a limited set of targeted interventions to improve health around the world are inadequate. We argue that a comprehensive systems perspective should guide health practice, education, research and policy. We propose key 'systems thinking' tools and strategies that have the potential for transformational change in health systems. Three overarching themes span these tools and strategies: collaboration across disciplines, sectors and organizations; ongoing, iterative learning; and transformational leadership. The proposed tools and strategies in this paper can be applied, in varying degrees, to every organization within health systems, from families and communities to national ministries of health. While our categorization is necessarily incomplete, this initial effort will provide a valuable contribution to the health systems strengthening debate, as the need for a more systemic, rigorous perspective in health has never been greater.

  17. A treatment strategy for waste waters resulting from uranium mine decommissioning in Romania

    International Nuclear Information System (INIS)

    The exploitation activities in two important uranium mining areas in Romania are foreseen to be closed down in correlation with the national energy policy and nuclear strategy. This close down activity involves a number of technical decisions for environmental restoration. Reducing the contamination due to radioactive water of these areas, during the operation period and after the close down period, is one of the main components of the environment rehabilitation strategy. In this paper, the current situation and the program foreseen for ground and surface water treatment at an uranium mining unit situated in the S-W of Romania are presented. This program was established on the base of the results of our research carried out in order to decrease the content of radioactive elements. After closing down the mining facility, naturally flooding waters should be evacuated at the surface by a pump system and properly treated. A station for water decontamination is under construction. The underground water decontamination is based on two methods: ion exchange for uranium and adsorption on active coal for Ra-226. The technological flow chart of the treatment installation is realized on the basis of laboratory and industrial research and it will output treated water with less than 60 mg solid/l, 0.021 mg U/l and 0.088 Bq Ra-226/l. The installation is able to treat contaminated water flow rates between 10 and 30 l/s at a cost of about 0.1 USD/m3. The total investment cost is estimated to be 9.7 - 12.6 billions RO Lei (USD 500.000 - 650.000), depending of the treatment capacity. (authors)

    Private companies will play a critical role in implementation of successful climate policies. However, until now little is known about triggers to develop corporate climate strategies. In a USA-Europe co-operation, researchers have investigated emerging climate strategies in the oil, automobile, chemical and bank and insurance industries. A focal question was whether strategies of EU based corporations differ systematically from USA based corporations. Results show rather sectorial specific developments. In most sectors, i.e. oil, automobile and banks, European corporations generally tend to have more advanced climate policies than their USA counterparts, but this does not apply to chemical companies. In the automobile industry, USA and Europe show convergent strategies. In the other sectors, convergence is not clearly visible

    Full Text Available Abstract Background Efficient delivery strategies for health interventions are essential for high and sustainable coverage. We report impact of a change in programmatic delivery strategy from routine delivery through the Expanded Programme on Immunization (EPI+ approach to twice-yearly mass distribution campaigns on coverage of vitamin A supplementation in Tanzania Methods We investigated disparities in age, sex, socio-economic status, nutritional status and maternal education within vitamin A coverage in children between 1 and 2 years of age from two independent household level child health surveys conducted (1 during a continuous universal targeting scheme based on routine EPI contacts for children aged 9, 15 and 21 months (1999; and (2 three years later after the introduction of twice-yearly vitamin A supplementation campaigns for children aged 6 months to 5 years, a 6-monthly universal targeting scheme (2002. A representative cluster sample of approximately 2,400 rural households was obtained from Rufiji, Morogoro Rural, Kilombero and Ulanga districts. A modular questionnaire about the health of all children under the age of five was administered to consenting heads of households and caretakers of children. Information on the use of child health interventions including vitamin A was asked. Results Coverage of vitamin A supplementation among 1–2 year old children increased from 13% [95% CI 10–18%] in 1999 to 76% [95%CI 72–81%] in 2002. In 2002 knowledge of two or more child health danger signs was negatively associated with vitamin A supplementation coverage (80% versus 70% (p = 0.04. Nevertheless, we did not find any disparities in coverage of vitamin A by district, gender, socio-economic status and DPT vaccinations. Conclusion Change in programmatic delivery of vitamin A supplementation was associated with a major improvement in coverage in Tanzania that was been sustained by repeated campaigns for at least three years.

    The evaluation of flood damages is a complex interdisciplinary task which demands great efforts on assessment and modelling processes. Several methods and models can be used in practice to evaluate flood damages. On the one hand, hydrological and hydrodynamic aspects of floods shall be modelled in order to forecast different characteristics of floods, e.g. return period, flood extent, water depth, duration of submersion and flow speed. Different hydrological assumptions can take place when determining return periods of extreme events. Several hydrodynamic models can be used to simulate floods. These models have different levels of complexity and different acquisition, implementation and maintenance costs. On the other hand, geographic, engineering, social and economic aspects of the system exposed to floods shall be assessed, e.g. assets location, vulnerability characteristics, susceptibility to suffer damages. Once again, several methods and datasets with different liability and different levels of feasibility can be used to assess these characteristics. Uncertainty exists all over the evaluation process. When reducing uncertainty on the evaluation results by improving the strategies used, we could generate the elevation of the costs of the evaluation and compromise its feasibility. To deal with feasibility of the evaluation process and with uncertainty on the evaluation results is a big scientific and operational challenge. The aim of this paper is to develop a research framework to analyze the impact of different strategies used to evaluate flood damages on the feasibility of the evaluation and on the liability of its results. The two main parts of the evaluation process are discussed: (1) the hydrodynamic simulation of flood events and its hydrological components and (2) the assessment of assets vulnerability to floods. The framework compares two aspects of the evaluation: uncertainty - variability of the evaluation results according to the choice of models and

    The Arctic temperature response to emissions of aerosols -- specifically black carbon (BC), organic carbon (OC), and sulfate -- depends on both the sector and the region where these emissions originate. Thus, the net Arctic temperature response to global aerosol emissions reductions will depend strongly on the blend of emissions sources being targeted. We use recently published equilibrium Arctic temperature response factors for BC, OC, and sulfate to estimate the range of present-day and future Arctic temperature changes from seven different aerosol emissions scenarios. Globally, Arctic temperature changes calculated from all of these emissions scenarios indicate that present-day emissions from the domestic and transportation sectors generate the majority of present-day Arctic warming from BC. However, in all of these scenarios, this warming is more than offset by cooling resulting from SO2 emissions from the energy sector. Thus, long-term climate mitigation strategies that are focused on reducing carbon dioxide (CO2) emissions from the energy sector could generate short-term, aerosol-induced Arctic warming. A properly phased approach that targets BC-rich emissions from the transportation sector as well as the domestic sectors in key regions -- while simultaneously working toward longer-term goals of CO2 mitigation -- could potentially avoid some amount of short-term Arctic warming.

  3. Climate Change Impacts and Adaptation Strategies in Spring Barley Production in the Czech Republic

    International Nuclear Information System (INIS)

    The crop model CERES-Barley was used to assess the impacts of increased concentration of atmospheric CO2 on growth and development of the most important spring cereal in Central and Western Europe, i.e., spring barley, and to examine possible adaptation strategies. Three experimental regions were selected to compare the climate change impacts in various climatic and pedological conditions. The analysis was based on multi-year crop model simulations run with daily weather series obtained by stochastic weather generator and included two yield levels: stressed yields and potential yields. Four climate change scenarios based on global climate models and representing 2 x CO2 climate were applied. Results: (1) The crop model is suitable for use in the given environment, e.g., the coefficient of determination between the simulated and experimental yields equals 0.88. (2) The indirect effect related to changed weather conditions is mostly negative. Its magnitude ranges from -19% to +5% for the four scenarios applied at the three regions. (3) The magnitude of the direct effect of doubled CO2 on the stressed yields for the three test sites is 35-55% in the present climate and 25-65% in the 2 x CO2 climates. (4) The stressed yields would increase in 2 x CO2 conditions by 13-52% when both direct and indirect effects were considered. (5) The impacts of doubled CO2 on potential yields are more uniform throughout the localities in comparison with the stressed yields. The magnitude of the indirect and direct effects ranges from -1 to -9% and from +31 to +33%, respectively. Superposition of both effects results in 19-30% increase of the potential yields. (6) Application of the earlier planting date (up to 60 days) would result in 15-22% increase of the yields in 2 x CO2 conditions. (7) Use of a cultivar with longer vegetation duration would bring 1.5% yield increase per one extra day of the vegetation season.

    Full Text Available Climate change adds an additional layer of complexity that needs to be considered in business strategy. For firms in the food industry, many of the important climate impacts are not directly related to food processing so a value chain approach to adaptation is recommended. However, there is a general lack of operational tools to support this. In this study, carbon and water footprints were conducted at a low-precision screening level in three case studies in Australia: Smith’s potato chips, OneHarvest Calypso™ mango and selected Treasury Wine Estates products. The approach was cost-effective when compared to high-definition studies intended to support environmental labels and declarations, yet provided useful identification of physical, financial, regulatory and reputational hotspots related to climate change. A combination of diagnostic footprinting, downscaled climate projection and semi-quantitative value chain analysis is proposed as a practical and relevant toolkit to inform climate adaptation strategies.

  5. Moving polewards in winter: a recent change in the migratory strategy of a pelagic seabird?

    Full Text Available Abstract Background During the non-breeding period, many birds migrate to milder areas, found closer to the equator than their breeding sites. Opposite movements are very rare. In the Southern Ocean, the abundance of 13C declines markedly with more southern latitude, providing a characteristic 13C isoscape. This can be used as a tracer for the movement of seabirds between breeding and inter-breeding areas, by comparing stable isotope ratios of feathers grown at different times of the year. Results We studied seasonal movements of Thin-billed prions (Aves, Procellariiformes, breeding at the Subantarctic Falkland/Malvinas Islands, compared with those of Wilson's storm-petrels breeding in the Antarctic South Shetland Islands. The two species showed opposite migratory movements. While Wilson's storm-petrels moved to warmer waters north of the Drake Passage in winter, Thin-billed prions showed a reversed movement towards more polar waters. Carbon stable isotope ratios in recent and historical feathers indicated that poleward winter movements of Thin-billed prions were less common historically (45% in 1913-1915, and have only recently become dominant (92% in 2003-2005, apparently in response to warming sea temperatures. Conclusions This study shows that pelagic seabirds can rapidly change migration strategies within populations, including migration towards more poleward waters in winter.

    The Mesoamerican region is considered to be one of the areas in the world most vulnerable to climate change. We developed a framework for quantifying the vulnerability of the livelihoods of coffee growers in Mesoamerica at regional and local levels and identify adaptation strategies. Following the Intergovernmental Panel on Climate Change (IPCC) concepts, vulnerability was defined as the combination of exposure, sensitivity and adaptive capacity. To quantify exposure, changes in the climatic suitability for coffee and other crops were predicted through niche modelling based on historical climate data and locations of coffee growing areas from Mexico, Guatemala, El Salvador and Nicaragua. Future climate projections were generated from 19 Global Circulation Models. Focus groups were used to identify nine indicators of sensitivity and eleven indicators of adaptive capacity, which were evaluated through semi-structured interviews with 558 coffee producers. Exposure, sensitivity and adaptive capacity were then condensed into an index of vulnerability, and adaptation strategies were identified in participatory workshops. Models predict that all target countries will experience a decrease in climatic suitability for growing Arabica coffee, with highest suitability loss for El Salvador and lowest loss for Mexico. High vulnerability resulted from loss in climatic suitability for coffee production and high sensitivity through variability of yields and out-migration of the work force. This was combined with low adaptation capacity as evidenced by poor post harvest infrastructure and in some cases poor access to credit and low levels of social organization. Nevertheless, the specific contributors to vulnerability varied strongly among countries, municipalities and families making general trends difficult to identify. Flexible strategies for adaption are therefore needed. Families need the support of government and institutions specialized in impacts of climate change and

    Full Text Available Abstract Background Intermittent preventive treatment of malaria in infants (IPTi using sulphadoxine-pyrimethamine and linked to the expanded programme on immunization (EPI is a promising strategy for malaria control in young children. As evidence grows on the efficacy of IPTi as public health strategy, information is needed so that this novel control tool can be put into practice promptly, once a policy recommendation is made to implement it. This paper describes the development of a behaviour change communication strategy to support implementation of IPTi by the routine health services in southern Tanzania, in the context of a five-year research programme evaluating the community effectiveness of IPTi. Methods Mixed methods including a rapid qualitative assessment and quantitative health facility survey were used to investigate communities' and providers' knowledge and practices relating to malaria, EPI, sulphadoxine-pyrimethamine and existing health posters. Results were applied to develop an appropriate behaviour change communication strategy for IPTi involving personal communication between mothers and health staff, supported by a brand name and two posters. Results Malaria in young children was considered to be a nuisance because it causes sleepless nights. Vaccination services were well accepted and their use was considered the mother's responsibility. Babies were generally taken for vaccination despite complaints about fevers and swellings after the injections. Sulphadoxine-pyrimethamine was widely used for malaria treatment and intermittent preventive treatment of malaria in pregnancy, despite widespread rumours of adverse reactions based on hearsay and newspaper reports. Almost all health providers said that they or their spouse were ready to take SP in pregnancy (96%, 223/242. A brand name, key messages and images were developed and pre-tested as behaviour change communication materials. The posters contained public health messages

We propose key ‘systems thinking’ tools and strategies that have the potential for transformational change in health systems...

    ROSETTA based on soil textural fractions. Simulation of water flow using automatic and non-automatic date was carried out by HYDRUS-1D independently. A good agreement from collected automatic and non-automatic data and modelled results can be recognized. General trend was captured, except for the outlier values as expected. Slightly differences were found between hydraulic properties obtained from laboratory determinations, and from inverse modelling from the two approaches. Differences up to 14% of flux through the lower boundary were detected between the two strategies According to results, automatic sensors have more resolution and then they're more appropriated to detect subtle changes of soil hydraulic properties. Nevertheless, if the aim of the research is to control the general trend of water dynamics, no significant differences were observed between the two systems.

    Halsnaes, K.

    1997-12-01

    This thesis presents a methodological and empirical discussion of the costs associated with implementing greenhouse gas reduction strategies in developing countries. It presents a methodological framework for national costing studies and evaluates a number of associated valuation methods. The methodological framework has been applied in several developing countries as part of a UNEP project in which the author has participated, and reference is made to the results of these country studies. Some of the theoretical issues associated with the determination of the costs of emission reductions are discussed with reference to a number of World Bank and UN guidelines for project analysis in developing countries. The use of several accounting prices is recommended for mitigation projects, with a distinction being made between internationally and domestically traded goods. The consequences of using different accounting prices are discussed with respect to the methodology applied in the UNEP country studies. In conclusion the thesis reviews the results of some of the most important international studies of greenhouse gas emissions in developing countries. The review, which encompasses a total of 27 country studies, was undertaken by the author for the Intergovernmental Panel of Climate Change, the IPCC. Its conclusion is that the UNEP methodological framework and associated country study results are consistent with the recommendations and conclusions of the IPCC. (EG) 23 refs.

    Ultra short (ps, fs) laser pulses are used, when high requirements concerning accuracy, surface roughness, heat affected zone etc. are demanded for surface structuring. Ps-laser systems that are suited to be operated in industrial environments are of great interest for many practical applications. Here results in the field of 3-d structuring (metals and transparent materials), induced processes and structuring of flexible solar cells will be presented. Beside the pulse duration, which is given by the laser system, the user has a wide variety of optimization parameters such as fluence, repetition rate and wavelength. Based on a simple model it will be shown, that there exist optimum laser parameters to achieve maximum volume ablation rates at a given average power. To take benefit of these optimum parameters and to prevent harmful effects like plasma shielding and surface melting, adapted structuring strategies, depending on the requirements, have to be used. Today's ultra short pulsed systems have average powers from a few W up to a few 10W at high repetition rates. The actual available beam guiding systems are limited and can often not fulfill the requirements needed for high throughput structuring with optimized parameters. Based on the achieved results, the needs for future beam guiding systems will be discussed.

    2013-08-01

    Full Text Available Moving to agile through a well-defined strategy and framework is essential and this socio-technical process should be studied in deep. Advantages and earned values of agile approach in software industry motivate a lot of companies to try to use agile methods in their software product lines. Transformation process to agile methods is not easy and because of its nature, takes a long time. Since agile transformation needs organizational mutation, companies are faced with many challenges during this process. While several studies have been conducted for how to use agile methods, some other studies have focused on finding obstacles in agile adoption process. However, previous studies are valuable, but each of them has focused the change process from a particular perspective. In this study we discuss the dimensions of agile transformation process from a wider perspective. We will show that focusing on agile adoption is not the only master key for success in agile transformation process and we need to define an agile change management strategy for this organizational metamorphosis. This strategy should consider all aspects of changing approach and is underpinning of achievement in agile transformation process through substantive transformation experiences.

    Full Text Available A better understanding of climate change and variability (CCV from the farmer’s perspective is a key to prioritizing measures to address and prepare for its consequences. A survey involving 150 farmers was thus conducted in Makueni County, Kenya to document farmers’; perception, experience and adaptation strategies to CCV. About 86% of farmers perceived CCV as a major challenge with 53% indicating that significant changes in climate would manifest in 10-20 years. Significant changes in rainfall amounts and distribution had occurred over the years and were rated by 60% of farmers as the frequently experienced aspect of CCV. About 33% of farmers had heard of but not used decision support tools (DST to inform their agricultural activities. Workshops and seminars were reported by 67% of farmers as principal sources of information on CCV. Additionally, 50% of farmers relied on traditional knowledge for weather prediction. Only 20% of farmers had alternative strategies; agroforestry and growing drought tolerant crops particularly sorghum and cowpea, to minimize effects of CCV. Another 67% of farmers prioritized; terracing, ridging and water harvesting as adaptation strategies to minimize negative effects of CCV. The farmers were thus aware of CCV and through experience, backed with traditional technical knowledge, had gained prerequisite skills for addressing its negative effects. Nevertheless farmers’ agricultural practices could be improved by use of forecasted weather data and application of DST. Consequently enhancing farmers’ preparedness to tackle challenges posed by CCV.

    2014-12-01

    This study suggests a robust prioritization framework for climate change adaptation strategies under multiple climate change scenarios with a case study of selecting sites for reusing treated wastewater (TWW) in a Korean urban watershed. The framework utilizes various multi-criteria decision making techniques, including the VIKOR method and the Shannon entropy-based weights. In this case study, the sustainability of TWW use is quantified with indicator-based approaches with the DPSIR framework, which considers both hydro-environmental and socio-economic aspects of the watershed management. Under the various climate change scenarios, the hydro-environmental responses to reusing TWW in potential alternative sub-watersheds are determined using the Hydrologic Simulation Program in Fortran (HSPF). The socio-economic indicators are obtained from the statistical databases. Sustainability scores for multiple scenarios are estimated individually and then integrated with the proposed approach. At last, the suggested framework allows us to prioritize adaptation strategies in a robust manner with varying levels of compromise between utility-based and regret-based strategies.

    The oil industry is particularly concerned with the issue of climate change. The implementation of Greenhouse Gases (GHG) reduction policies can be perceived as an additional environmental constraint for the management of the production chain. It is also represents a first step towards a possible decarbonization of the economy. In the long-term, the fight against global warming calls thus into question the activity level of petroleum companies. Confronted with this, still uncertain, new environmental deal, some petroleum multinationals adopt proactive behaviors, e.g. with voluntary commitments to reduce GHG emissions, or with investments in alternative technologies. First of all, we present the potential economic impacts of the Kyoto Protocol on oil industry. Then, we conduct a comparative analysis of the 'Kyoto risk' for the five largest multinationals of this sector according to their activities and their geographical implantations. Then, for the purpose to interpreting proactive strategies of firms such as BP and Shell, we examine various explanations including 'win-win', public image and the response to broad societal needs. This leads us to formalize the proactive behavior as an anticipatory management of carbon contestability, particularly perceptible in financial markets. Lastly, we try to justify economically investments of companies in the field of alternative energy sources and technologies through the lens of real options theory and by a management of the exhaustible fossil resources.

    Northern Algeria, located along the Eurasiatic-African boundary plate is characterised by a moderate to strong seismic activity. During History, some violent earthquakes occurred mainly in the Atlas region, particularly in the Tellian area, leading sometimes to destruction of major cities of Algeria (Algiers, 1716; Oran, 1790; Blida, 1825; El Asnam, 1980; Constantine, 1985; Boumerdes, 2003…). In order to improve the knowledge of the deformation pattern of the Atlasic region, and more globally of the African (Nubia)-Eurasia plate boundary along the Algerian margin, the Research Center of Astronomy, Astrophysics and Geophysics (CRAAG) started since six year to implement a permanent GPS network. The REGAT (REseau Géodésique de l'Atlas), consists on a set of 56 continuous GPS stations deployed in the Atlas region, from the coastal area to the Sahara Platform with one station at Tamanrasset, in the southern part of the country. The deployment strategy consisted in two phases: - The first one began on 2004 with 14 stations installed - The second phase, which started in 2011concerns a set of 42 stations. We present here the procedure used to collect, store and process the GPS data from the REGAT network and present the preliminary results of the stations which observed more than three years.

    As science literacy is falling in the United States, our world continues to become more complex. Everyone now requires an understanding of science, technology, and the relationship of interconnected systems in order to successfully navigate the complex issues facing us. Scientists are a critical resource, bringing to the table an understanding of the nature of science as a process, as well as up-to-the-minute scientific content. They can function in a wide range of capacities in education and public outreach (EPO) to meet some of the learning challenges of teachers, students, and the general public. Societies that work directly with scientists, such as the American Astronomical Society (AAS) and the Division for Planetary Sciences (DPS) are interested in understanding how their member scientists view the act of reaching out, how they do it, and how the DPS can continue to support them as they engage with a variety of audiences in an EPO capacity. To this end, we (the NASA Science Mission Directorate Planetary Science Forum and DPS leadership) conducted a series of semi-structured interviews with a subsection of DPS members to learn more about their attitudes and needs, and to begin to pinpoint opportunities and strategies for future consideration. Presented here are our preliminary results and the ideas generated for further conversations.

  12. Nuclear power plant control computer aging management strategy, implementation and results

    International Nuclear Information System (INIS)

    The digital control computers (DCCs) at Ontario Power Generation (OPG) nuclear plants at Pickering A and B and Darlington are more than thirty years old. No technical support is available from the original equipment manufacturers of the DCCs for Pickering A (IBM 1800), Pickering B (Varian V72) or Darlington (DEC 11/70). Yet the DCCs are vital to plant operations since they provide reactor control, main control room annunciation and process displays, fuel handling controls, and control of several other important process systems. The DCCs are dual-redundant to achieve the necessary system reliability and if at least one channel of the dual DCC system is not available, the Generating Unit must be shut down. The DCC aging management strategy was initiated at Pickering A since it had the oldest DCCs. The initial focus was to acquire and stockpile as many IBM 1800 spare systems as possible in order to ensure the long-term availability of necessary replacement parts. This was driven by the understanding of the inherent value of retaining the proven and stable control software running on the Pickering A DCCs and of the inherent risk in trying to migrate this software to a different hardware platform. The Pickering A control programs, like all the other DCC control programs at OPG, are written in assembler language running under a custom real-time executive. Process control time constants are embedded within this combination of hardware and software. Also embedded therein are the self-checks and fault responses which are essential to reliable and fail-safe DCC operation. A fundamental element of the DCC aging management strategy has been to retain the integrity of the time-proven control programs and the infrastructure in which they operate. For Pickering A, it became obvious in the early 1990's that acquiring spare parts alone would not be sufficient to sustain the reliable life of the IBM 1800 DCCs.

    It is an important issue whether irrigation systems can continuously provide quality service under climate change conditions. The streamflow irrigation system, which delivers water from a river directly, is still widely applied in Taiwan. Due to the impacts of climate change, the amount of available streamflow may decrease during dry season and higher variation of flows can be expected, which influences irrigation systems severely. Furthermore, sub-irrigation areas may have different levels of impacts under climate change. Instead of applying the adaptation strategies to the whole irrigation areas, different adaptive measures should be considered according to the vulnerability of each sub-irrigation area in order to face the impacts of climate change. The purposes of this study include defining the carrying capacity of an irrigation system, developing spatial distributed assessment methods through geographic information system and discussing how to develop adaptation systems for the areas which are more vulnerable. In this study, both agricultural and domestic water supply systems of the Touchien creek watershed are considered in this study. Future water demands of agriculture are estimated under the change of temperature and rainfall, and the amount of water supply to each sub-irrigation area is calculated according to its area and water losses. As for public water uses, the most restrict scenarios are taken in, e.g. the largest impact toward agriculture in the Touchien creek watershed. Then, the vulnerability of sub-irrigation areas is quantified by agricultural shortage index (ASI). ASI represents the percentage of crop yields in that area comparing with its potential crop yields. At last, the spatial distribution of vulnerability is established in order to emphasize the climate change impacts on each sub-irrigation area and to analyze their possible responses. Possible distributed adaptive strategies are proposed in this study too. Keywords: Vulnerability

    Energy typically represents the single largest controllable cost in manufacturing, and is under constant scrutiny by all levels of management. In this paper we will examine the role and components of an energy management strategy, and focus on the benefits of looking at the strategy from a business perspective. We will then examine the role that an effective program, either existing or new, can play in a collaborative manufacturing environment, and how these improvements can reduce energy requirements while maintaining, or improving productivity.

    Iwarsson, Jenny

    2015-12-01

    A typical goal of voice therapy is a behavioral change in the patient's everyday speech. The SLP's plan for voice therapy should therefore optimally include strategies for automatization. The aim of the present study was to identify and describe factors that promote behavioral learning and habit change in voice behavior and have the potential to affect patient compliance and thus therapy outcome. Research literature from the areas of motor and behavioral learning, habit formation, and habit change was consulted. Also, specific elements from personal experience of clinical voice therapy are described and discussed from a learning theory perspective. Nine factors that seem to be relevant to facilitate behavioral learning and habit change in voice therapy are presented, together with related practical strategies and theoretical underpinnings. These are: 1) Cue-altering; 2) Attention exercises; 3) Repetition; 4) Cognitive activation; 5) Negative practice; 6) Inhibition through interruption; 7) Decomposing complex behavior; 8) The 'each time-every time' principle; and 9) Successive implementation of automaticity.

  17. Climate Change Adaptation Strategies and Farm-level Efficiency in Food Crop Production in Southwestern, Nigeria

    Directory of Open Access Journals (Sweden)

    Otitoju, MA.

    2014-01-01

    Full Text Available Food crop yields depend largely on prevailing climate conditions, especially in Africa, where rain-fed agriculture predominate. The extent to which climate impacts are felt depends principally on the adaptation measures used by farmers. This study focused on the effect of climate change adaptation strategies on farm-level technical efficiency. The study used primary data collected from 360 randomly selected farmers in Southwest Nigeria. Cobb-Douglass stochastic frontier production model was used to analyse the data. Multiple cropping, land fragmentation, multiple planting dates, mulching and cover cropping were the major climate change adaptation strategies employed by the farmers. While land fragmentation and multiple planting dates had significant positive relationships, years of climate change awareness and social capital had significant inverse relationships, with technical inefficiency. This may be because while land fragmentation may hinder farm mechanization, multiple planting dates may increase the monotonousness and drudgery of farming. On the other hand, social capital and climate change awareness could help ameliorate the effects of, particularly, land fragmentation through resource pooling. It is therefore recommended that the farmers be encouraged to form cooperative societies so as to leverage their resource status through collective efforts.

    1995-06-01

    THE PURPOSES OF THIS STUDY WERE TO: 1) identify the major differences between the CAAHEP athletic training educational essentials and NATA educational essentials, and 2) address the potential impact of those changes on educational programs. Three of the five athletic trainers on the JRC-AT responded to an eight-item questionnaire. Responses from the survey were compared and contrasted. CAAHEP accreditation guidelines will permit more flexibility in teaching methods than did the NATA guidelines. CAAHEP does not mandate a minimum of 800 hours of clinical experience, but the NATA Board of Certification requires the completion of 800 hours before taking the certification exam. CAAHEP policies regarding fair practice and nondiscriminatory policies were believed to be more strict, thus assuring that students are not misused in a service capacity, and are exposed to a variety of male and female sports. Financially, the accreditation fees were increased. Long-term changes were anticipated as: 1) administrative and content essentials being weighed separately, 2) departmental move to medical or allied health departments, and 3) increased academic responsibilities for program directors.

    This paper reviews assessment of climate change impacts on economy, society and ecological environment in the coastal areas of South China based on published literatures;it also proposes suitable adaptation strategies and counter-measures. Review shows that climate change has resulted in sea level rise in the coastal areas of South China, increasing the occurrence and intensity of storm surges, aggravating the influence of saltwater intrusion, coastal erosion, urban drainage and flood control, threatening the coastal facility and infrastructures, inundating lowland areas, offsetting mudflat silting, and degrading mangroves and coral reef ecosystem. Therefore, in order to reduce the adverse effects of climate change and to support the sustainable development in the coastal areas of South China, it is critical to improve the monitoring and early warning system, enhance prevention criteria, fortify coastal protection engineering, strengthen salt tide prevention, and reinforce the ecological restoration and protection.

  20. Implementing a university e-learning strategy: levers for change within academic schools

    Rhona Sharpe

    2006-12-01

    Full Text Available This paper describes the implementation of an e-learning strategy at a single higher education institution in terms of the levers used to promote effective uptake and ensure sustainable embedding. The focus of this work was at the level of the academic school using a range of change practices including the appointment of school-based learning technologists and e-learning champions, supporting schools to write their own strategies, a pedagogical framework of engaging with e-learning, and curriculum development and evaluation of school-supported projects. It is clear that the implementation of the e-learning strategy has led to a large and increasing proportion of our students experiencing blended learning. In addition, there are initial indications that this has enhanced some learning and teaching processes. Where there has been sustainable embedding of effective e-learning, the following levers were identified as particularly important: flexibility in practices that allow schools to contextualise their plans for change, the facilitation of communities of key staff and creating opportunities for staff to voice and challenge their beliefs about e-learning.

    The circumpolar north is uniquely vulnerable to the health impacts of climate change. While international Arctic collaboration on health has enhanced partnerships and advanced the health of inhabitants, significant challenges lie ahead. One Health is an approach that considers the connections between the environment, plant, animal and human health. Understanding this is increasingly critical in assessing the impact of global climate change on the health of Arctic inhabitants. The effects of climate change are complex and difficult to predict with certainty. Health risks include changes in the distribution of infectious disease, expansion of zoonotic diseases and vectors, changing migration patterns, impacts on food security and changes in water availability and quality, among others. A regional network of diverse stakeholder and transdisciplinary specialists from circumpolar nations and Indigenous groups can advance the understanding of complex climate-driven health risks and provide community-based strategies for early identification, prevention and adaption of health risks in human, animals and environment. We propose a regional One Health approach for assessing interactions at the Arctic human–animal–environment interface to enhance the understanding of, and response to, the complexities of climate change on the health of the Arctic inhabitants.

    Full Text Available Consumer researchers have most frequently looked at the influence the marketplace has on consumers’ identity projects, while the reverse process – how consumers’ identity projects influence the marketplace and general culture – is an important issue that has received less attention. Aiming to contribute to the development of this literature, we conduct a qualitative netnographic investigation of the Fat Acceptance Movement, an online-based movement led by consumer-activists who attempt to change societal attitudes about people who are fat. Our main goal is, therefore, to investigate how consumer activists who congregate online, that is, cyberactivists, reframe market offers while attempting to promote market and cultural change. We identify several rhetorical strategies employed by online consumer activists in their quests to change themselves, other consumers, and the broader culture. Our findings advance consumer research on how consumers may mobilize resources to initiate and promote self-, market-, and cultural transformations.

    2009-01-01

    This study examined the associations between older adults’ daily physical symptoms (e.g., chest pain or difficulty breathing) and 2-year changes in chronic health problems (e.g., cardiovascular disease or cancer) and in functional problems (e.g., difficulty dressing or moving around at home). We reasoned that these associations depend on a person’s active control processes aimed at counteracting physical health problems (i.e., health-engagement control strategies, or HECS). In particular, we hypothesized that high levels of HECS buffer the adverse effect of daily physical symptoms on increases in chronic and functional health problems. We found that daily physical symptoms were associated with declines in chronic and functional health among older adults who were not engaged in addressing their health problems, but not among their counterparts who reported high levels of HECS. These findings suggest that active control strategies play an important role in the maintenance of older adults’ physical health. PMID:18578842

    2008-05-01

    Recent research in science education suggests that learner-centered instructional strategies can promote more learning than traditional teacher-based strategies such as lecture. However, the adoption of such strategies by instructors can elicit many concerns, including, for example, concerns of increased time requirements for preparation and grading, reduced content coverage, reactions of students and colleagues, and, of course, student achievement. Ethan, an astronomy instructor early in his career, recently adopted learner-centered strategies into his introductory course for nonscience majors on stars and galaxies. He shared the concerns listed above, but after receiving training in learner-centered strategies from the Center for Astronomy Education and support from an experienced colleague while implementing the changes for the first time, Ethan's overall reaction was a positive one. Although the preparation time was somewhat higher than would have been required had he repeated his previous semester, Ethan felt that it was worth it to move away from lecture-only style and to incorporate learner-centered strategies into his course. For him, it simply felt more gratifying when he walked out of the classroom after using learner-centered methods than it had when he used only lecture. He also felt that many students learned more than those in previous lecture-based course offerings, and that their increased active participation during the class was a constructive change. In fact, average exam scores were comparable or higher than two previous semesters, as were student evaluations. Overall, Ethan felt that the integration of learner-centered strategies was well worth the time and effort, as evidenced by his statement, "I'll never go back to lecture-only again!"

  7. The surgical treatment strategy and results of parasellar meningiomas in the era of radiosurgery

    International Nuclear Information System (INIS)

    We evaluated the surgical treatment results of parasellar meningiomas in the era of radiosurgery. We treated 24 patients of parasellar meningiomas surgically. The median age was 60 yrs (ranging from 29 to 82 yrs). The most common tumor location was the sphenoid ridge in 12 patients and the tuberculum sellae in 7 patients. The pterional approach using fronto-temporal craniotomy was performed for all patients. The residual or recurrent tumors were treated by gamma knife radiosurgery (GKS). We are able to follow up these cases for a median of 3.8 yrs (ranging from 1 to 8 yrs) after the operations. The radicality of tumor resection was Simpson grade II in 13 patients (54%), grade III in 3 patients (13%) and grade IV in 7 patients (33%). Clinical improvement was achieved in 81% of the patients. Of the patients who had visual disturbance preoperatively, 8 patients (73%) showed improvement, but 3 patients suffered deterioration postoperatively. None of the patients died. One patient suffered transient memory disturbance and one patient suffered mild facial numbness postoperatively. Boost radiosurgery for the residual tumors was performed for six patients and tumor growth control was able to be achieved in all patients, with a median of 3.1 years follow-up period (ranging from 0.5 to 6 yrs). Five patients with tumor regrowth or recurrence were treated by GKS. We recommend fronto-temporal craniotomy with nonradical resection for parasellar meningiomas and radiosurgery for residual and recurrent tumors. This strategy will achieve good functional outcome with long-term tumor growth control. (author)

    This research investigates the impact of climate change on the mobility of people in four settlements in Senegal: Ngueye Ngueye, Gandiole, the Senegal River delta and Ourossogui. A qualitative approach involving semi-structured interviews and focus groups was used to determine how daily life in these communities is being affected by environmental change. Some migrants spend long periods as far afield as Mauritania, the Gambia or Spain, while others stay closer to home, going to places like Saint-Louis, Dakar and Mbour for short periods. Mobility is an opportunity for migrants to generate funds and send money home. It is a key factor in adaptation to climate change, as a strategy for survival and for diversifying incomes. The problems encountered in the ecological study zones are not entirely due to climate change, for migration is also triggered by factors such as the opening of the breach in Saint-Louis or lack of support for rural development. However, climate change is certainly accelerating disruptions and transformations in the study sites. Moreover, while migrants' financial transfers help improve daily life for some families, they also increase socio-economic inequalities between households that include migrants and those that do not. People are moving away from (but not necessarily abandoning) purely agricultural livelihoods and seeking to diversify their sources of income. This may come from migration, or from artisanal activities undertaken in the locality - such as metalwork, woodwork, sewing or hairdressing. Another option that many women have taken is using micro-credit facilities to start processing local produce, crushing groundnuts and preparing cereals to sell at the weekly markets. Other adaptation strategies are developed and adopted through technical innovations or awareness-raising and educational activities. These activities often require institutional support from the State or from NGOs involved in implementing projects and helping

    Conductive-atomic force microscopy has been successfully used for characterizing recorded marks on commercial digital versatile disk and Blu-ray disk. Nano recorded marks beyond diffraction limit are imaged with high spatial resolution and excellent contrast of conductivity. The smallest mark size resolved is around 23.5 nm which is limited by background spots around 18.5 nm. The results of different optical power and writing strategy on the size, shape, and close packed writing process of recorded marks clearly show the opto-thermal response of phase-change recording layer.

  10. Land use and management change under climate change adaptation and mitigation strategies: a U.S. case study

    Mu, Jianhong E.; Wein, Anne; McCarl, Bruce

    2015-01-01

    We examine the effects of crop management adaptation and climate mitigation strategies on land use and land management, plus on related environmental and economic outcomes. We find that crop management adaptation (e.g. crop mix, new species) increases Greenhouse gas (GHG) emissions by 1.7 % under a more severe climate projection while a carbon price reduces total forest and agriculture GHG annual flux by 15 % and 9 %, respectively. This shows that trade-offs are likely between mitigation and adaptation. Climate change coupled with crop management adaptation has small and mostly negative effects on welfare; mitigation, which is implemented as a carbon price starting at $15 per metric ton carbon dioxide (CO2) equivalent with a 5 % annual increase rate, bolsters welfare carbon payments. When both crop management adaptation and carbon price are implemented the effects of the latter dominates.

  11. Envisioning Adaptive Strategies to Change: Participatory Scenarios for Agropastoral Semiarid Systems in Nicaragua

    2011-03-01

    Full Text Available Historically, the semiarid social–ecological systems of the dry Central American corridor have proven resilient to pressures. However, in the last century, these systems have experienced huge environmental and socioeconomic changes that have increased the vulnerability of local livelihoods to shocks. New approaches are needed to capture complex, uncertain, cross-scale and nonlinear relationships among drivers of change and vulnerability. Therefore, to tackle this challenge, we have applied a participatory and interdisciplinary methodological framework of vulnerability assessment to a case study in northern Nicaragua. We triangulated a range of information and data from participatory and scientific research to explore historical and current drivers of changes that affect the system’s components and indicators of vulnerability, represented in a 3-dimensional space in terms of ecological resilience, the socioeconomic ability of individuals to adapt to change, and an institutional capacity to buffer and respond to crisis. A projection of climatic changes combined with a participatory scenario analysis helped, then, to heuristically analyze tendencies of vulnerability in the future and to explore what policy options might enhance the system’s adaptive capacity to face new pressures. Our work primarily contributes to an empirical understanding of key factors that influence vulnerability and learning about local strategies to adapt to change in semiarid agropastoral systems in Central America. We also make a methodological contribution by testing the use of a multidimensional vulnerability framework as a way of stimulating discussion among researchers, local stakeholders, and policy makers.

  12. EFFECT OF CLIMATE CHANGE ON DAIRY PRODUCTION IN BOTSWANA AND ITS SUITABLE MITIGATION STRATEGIES

    Directory of Open Access Journals (Sweden)

    J. C. MOREKI

    2013-11-01

    Full Text Available This paper explores the effects of climate change on dairy production in Botswana and mitigation strategies are suggested. Dairy farming has not experienced growth over time rendering the country heavily dependent on milk imports. National dairy herd is estimated to be approximately 5000 and per capita consumption of milk about 32.5 litres per person per year. Currently, Botswana is experiencing average high temperatures and low rainfall, frequent droughts and scarcity of both ground and surface water, which all contribute to low livestock and crop productivity. Changes in rainfall patterns, frequent droughts, high incidences of animal diseases (e.g., mastitis and FMD and parasites, and high environmental temperatures cause significant decrease in livestock productivity. For dairy animals, there is a decline in milk yield and reduced animal weight gain due mainly to high temperatures and inadequate feeds. Mitigation strategies comprise using smaller dairy breeds such as Jersey and Brown Swiss and local Tswana breed, growing fodder crops and utilization of crop residues and constructing cow sheds. Thus, the effects of climate change on dairy cattle production are real and require immediate attention if they are to be minimized or managed properly to attain higher milk production.

    This paper argues that a discursive shift is taking place in Dutch water policy, from `a battle against water¿ to `living with water¿ or `accommodating water¿. Yet we ask ourselves whether this shift is just an adaptation strategy of the existing elite group of water managers, who pay lip-service to new management approaches in order to maintain their vested interests, as some authors claim, or whether it implies `deep¿ institutional change, e.g. in terms of the emergence of new water institu...

    Since many centuries, low lying areas at the German North Sea coast are intensively managed by water boards and dike boards. Sophisticated water management systems have been developed in order to keep the water out of the low lying areas in wet periods, while in some regions additional water is needed in dry periods for agricultural and ecological purposes. For example in the Wesermarsch region, a water management system has been developed in historical times, draining the landscape in winter time by means of channels, ditches, gates, sluices and pumping stations. In contrast, in summer time water is conducted from Weser River into the Wesermarsch region to serve watering of animals, fencing grazing areas and ensuring a continuous flow in the marsh watercourses. Doing so, maintaining soil fertility is guaranteed for agriculture as well as protection against floods, sustaining river ecology and traditional livestock farming. Due to climate variability and river engineering, the water management of the Wesermarsch already runs into problems because watering in summer cannot be assured any longer in sufficient water quality. During high tides, salt water from the North Sea is flowing upstream into the Weser estuary, generating brackish conditions in the lower Weser River. In addition, soil subsidence and soil mineralization of marsh and peat soils as well as the sea level rise increase the necessary pumping frequency and the emerging energy costs. The expected future climate change will further aggravate those problems and require an adaptation of the current management system. This presentation introduces the concept behind and preliminary results of an integrative and participatory project, aiming at the development of a new water management strategy adapted to the regional climate change likely to occur until year 2050. In close cooperation with a number of regional stakeholders and based on the priorities with respect to the future development of the region

  20. Changes in the chemical and physicochemical properties of the solid fraction of cattle slurry during composting using different aeration strategies.

    Replacement of peat as a growing medium by a renewable material, such as an organic waste, is an issue of concern since harvesting of peat has a considerable environmental impact and, actually, it is a non-renewable resource. Cattle manure is a readily available organic waste, which means that once it goes through the composting process, it can be used as an alternative to peat, specifically, the solid fraction obtained from mechanical liquid-solid separation of cattle slurry (SF). Studies have shown it to be suitable for such uses. The purpose of this study was to detect possible changes in the physicochemical and chemical properties of SF when it is composted using different aeration strategies, with an emphasis on the changes that would make it feasible for use as a substrate. With this aim in mind, an experiment was designed with three aeration strategies that would be used during composting. The first consisted of applying air through a static method (forced ventilation). The second involved improving aeration by adding a bulking agent and a dynamic turning method. In the third strategy, aeration was carried out by turning (control). The results show that the different aeration strategies had a clear effect on the evolution of pH, electrical conductivity (EC), nitrate-N, ammonia-N and bicarbonate content. Nitrification was favored under good aeration conditions using the static composting method, probably due to the greater availability of ammonia-N that was transformed into nitrate-N. In general, the low buffering capacity allowed for a reduction of the pH during the curing stage of composting (in conjunction with low temperatures during this period), a characteristic that favors the use of this compost as a growing medium. We also conclude that measuring bicarbonate levels during composting could be used as an indicator of the possible acidification of the material and as a way of evaluating the level of material aeration.

    This contribution summarizes the strategy used by Wuhan University (WHU) to determine precise orbit and clock products for Multi-GNSS Experiment (MGEX) of the International GNSS Service (IGS). In particular, the satellite attitude, phase center corrections, solar radiation pressure model developed and used for BDS satellites are addressed. In addition, this contribution analyzes the orbit and clock quality of the quad-constellation products from MGEX Analysis Centers (ACs) for a common time period of 1 year (2014). With IGS final GPS and GLONASS products as the reference, Multi-GNSS products of WHU (indicated by WUM) show the best agreement among these products from all MGEX ACs in both accuracy and stability. 3D Day Boundary Discontinuities (DBDs) range from 8 to 27 cm for Galileo-IOV satellites among all ACs' products, whereas WUM ones are the largest (about 26.2 cm). Among three types of BDS satellites, MEOs show the smallest DBDs from 10 to 27 cm, whereas the DBDs for all ACs products are at decimeter to meter level for GEOs and one to three decimeter for IGSOs, respectively. As to the satellite laser ranging (SLR) validation for Galileo-IOV satellites, the accuracy evaluated by SLR residuals is at the one decimeter level with the well-known systematic bias of about -5 cm for all ACs. For BDS satellites, the accuracy could reach decimeter level, one decimeter level, and centimeter level for GEOs, IGSOs, and MEOs, respectively. However, there is a noticeable bias in GEO SLR residuals. In addition, systematic errors dependent on orbit angle related to mismodeled solar radiation pressure (SRP) are present for BDS GEOs and IGSOs. The results of Multi-GNSS combined kinematic PPP demonstrate that the best accuracy of position and fastest convergence speed have been achieved using WUM products, particularly in the Up direction. Furthermore, the accuracy of static BDS only PPP degrades when the BDS IGSO and MEO satellites switches to orbit-normal orientation

    Kindelan, Paz; Martin, Ana

    2014-05-01

    European universities are currently going through a process of change in order to meet the common goals set for higher education by the European Commission. They are revising their educational models to adjust them to the guidelines of the "Bologna Process" and are devising an institutional strategy for its implementation. In practical terms, this means aligning former national degrees and diplomas to standard European Bachelor and Masters degrees and PhD doctorates, by creating acknowledged professional qualification benchmarks that also include adjusted course lengths and contents. This process, in the end, mostly affects academic staff members who have a fundamental role to play in carrying out the pedagogical reforms on the teaching front. Besides presenting a commentary on the institutional approach of one particular technical university in Spain, the purpose of this paper is to propose, from the authors' point of view as lecturers, a strategy which has the potential to create a favourable atmosphere for carrying out such a reform. The article's main objective is to highlight a series of action points which may serve to reinforce and advance the main institutional strategy by relying on the powerful influence of its academic staff members.

    The purpose of this paper was to examine the State of Maryland as a case study of sustained change efforts in the service delivery system for children with significant behavioral health needs and their families. A punctuated equilibrium paradigm is introduced to describe Maryland's behavioral health system transformation over the course of three decades. The context and specific strategies that characterized Maryland's execution of its recent Mental Health Transformation State Incentive Grant are highlighted. There is a discussion of one of the pinnacle achievements of Maryland's transformation efforts, the recent statewide establishment of care management entities for children with behavioral health challenges, and its implications for behavioral health in the context of health care reform changes. This case study illustrates how a state can systematically and incrementally develop systems of care for children and families that are values-based, sustainable, and flexible. PMID:23657753

    Altshuler, J L; Ruble, D N

    1989-12-01

    Children at 3 age levels (5-6 1/2, 7 1/2-9, and 10-12 years) were interviewed to determine their spontaneous suggestions of coping strategies designed to manage frustration caused by waiting for a desired object (positive valence) and fear caused by waiting for an unpleasant event (negative valence) in uncontrollable situations. Subjects' responses were grouped into categories based on coping techniques discussed in the adult coping literature on a continuum from approach to avoidance techniques. The avoidance tactics, the main focus of interest, were further divided into 4 distinct forms. In contrast to investigations of children's coping in more controllable situations, approach strategies were very infrequently mentioned. An age increase was found in the proportion of cognitive distraction strategies suggested, but behavioral distraction strategies were most frequently suggested by children at all age levels and did not differ significantly across age. The developmental differences were particularly evident for the negative valence scenarios and, within the negative valence scenarios, for the story likely to be the most stressful to young children--getting a shot. The results are discussed in terms of possible reasons for age differences in cognitive but not behavioral distraction and their implications for children's ability to cope with uncontrollable stress.

    Land use change in rural China since the 1980s, induced by institution reforms, urbanization, industrializa-tion and population increase, has received more attention. However, case studies on how institution reforms affect farmers' livelihood strategies and drive land use change are scarce. By means of cropland plots investigations and in-terviews with farmers, this study examines livelihood strategy change and land use change in Danzam Village of Jinchuan County in the upper Dadu River watershed, eastern Tibetan Plateau, China. The results show that, during the collective system period, as surplus labor forces could not be transferred to the secondary and tertiary industries, they had to choose agricultural involution as their livelihood strategy, then the farmers had to produce more grains by land reclamation, increasing multiple cropping index, improving input of labor, fertilizer, pesticide and adopting advanced agricultural techniques. During the household responsibility system period, as labors being transferred to the secondary and tertiary industries, farmers chose livelihood diversification strategy. Therefore, labor input to grain planting was greatly reduced, which drove the transformation of grain to horticulture, vegetable or wasteland and decrease of multi-ple cropping index. This study provides a new insight into understanding linkages among institution reforms, liveli-hood strategy of smallholders and land use change in rural China.

    Full Text Available Climate change and variability are a threat to sustainable agricultural production in semi-arid areas of Malawi. Overdependence on subsistence rain-fed agriculture in these areas calls for the identification of sustainable adaptation strategies. A study was therefore conducted in Chikwawa, a semi-arid district in southern Malawi, to: (1 assess community’s perception of a changing climate against empirical evidence, (2 determine their local adaptive measures, (3 evaluate the potential of irrigated agriculture as an adaptive measure in household food security and (4 challenges over access to available water resources. The study employed focus group discussions and key informant interviews to assess people’s perceptions of climate change and variability and their desired interventions. To validate the people’s perceptions, rainfall and temperature data for the period 1960–2010 were analysed. A participatory complete randomised experimental design in both rain-fed and dry season–irrigated conditions was conducted to assess a maize cropping system that would improve adaptation. The study established persistent declining yields from rain-fed production in part because of perennial rainfall failure. In response, the community has shifted its focus to irrigation as an adaptation strategy, which has in turn triggered water conflicts in the community over the control of the resource. Water legislation however fails to adequately provide for rules governing sharing of water resources between various stakeholders. This article therefore recommends development of an appropriate institutional framework that forms a strong basis for equitable distribution of water for irrigation in areas most vulnerable to extreme climate events – including droughts and floods.Keywords: Food Security; Climate Change and Variability; Rainfall Variability; Irrigation; Water Resources; Governance Crisis

  13. Teaching strategies and conceptual change in a professional development program for science teachers of K--8

    Science.gov (United States)

    Shen, Ji

    This case study investigates two consecutive science courses for teachers of K-8 in a professional development program at Washington University. It aims (1) to trace the processes of the teachers' conceptual change; (2) to analyze the teaching strategies by course instructors; and (3) to try to establish possible links between the two. To achieve this goal, I build a modeling theory to account for the observations. The main body of the study consists of four sub-cases. The first two cases instantiate the elements of the modeling theory. The opening case of balance shows that learning tools and task structures shape the learning outcome, and discusses cycles of modeling. The case also delineates the strategy that the instructors employed---moving from concrete experience to abstract explanation. The second case of buoyancy demonstrates that the modeling theory is able to explain the origins and forming mechanism of the alternative conceptions held by the teachers. It also shows that the teaching strategies of using alternative conceptions, applying analogies and following a logical sequence helped the teachers build new models. The last two cases demonstrate the ways of improving the competence of modelers. The third case of physical models emphasizes the metacognition of the learner who builds models. It illustrates that teachers' level of self-awareness in learning is increased when the models are physical. It shows that the creativity of modeling is rooted in agency, curiosity, communicability, and confidence, and that a chain of transformation among models is the key of systematizing and forming knowledge. The last case of frames of reference tries to answer the question "what is the justification of models if there are alternatives?" The teachers employed different forms of justification which relied heavily on common sense, authority, relativism, and pragmatism, all of which are not rational. While discussing both the positive and negative traits of these

    In Western countries, complementary and alternative medicine (CAM) is more and more provided by practitioners and family doctors. To base this reality of health care provision on an evidence-base, academic medicine needs to be included in the development. In the study we aimed to gain information on a structured approach to include CAM in academic health centers. We conducted a semistructured interview study with leading experts of integrative medicine to analyze strategies of existing academic institutions of integrative medicine. The study sample consisted of a purposive sample of ten leaders that have successfully integrated CAM into medical schools in the USA, Great Britain, and Germany and the Director of the National Center for Alternative and Complementary Medicine. Analysis was based on content analysis. The prerequisite to foster change in academic medicine was a strong educational and professional background in academic medicine and research methodologies. With such a skill set, the interviewees identified a series of strategies to align themselves with colleagues from conventional medicine, such as creating common goals, networking, and establishing well-functioning research teams. In addition, there must be a vision of what should be needed to be at the center of all efforts in order to implement successful change. PMID:23093984

  17. Spot market natural gas strategies and reliability dealing with changing industry conditions

    International Nuclear Information System (INIS)

    Many in the energy industry thought the natural gas buying game had finally settled down to a predictable pattern in the 90's. After a tumultuous decade in the 80's they are ready to turn their attention to new challenges such as electricity wheeling and cogeneration. They were wrong. There is plenty of change left in the natural gas industry for the rest of the century. This growth will dramatically increase the number of options available to Energy Buyers, giving them new flexibility to design programs that meet goals for cost reduction, supply reliability, and administrative effort. However, with new options also come the responsibility for choices. Energy Managers of well designed gas programs will make these choices after careful consideration of the pro's and con's of each option. In short, the effective Buyer will develop a natural gas strategy. This report will begin by reviewing the basic types of change occurring in the industry, and then discuss some of the varied strategy options available to the Energy Buyer

    2006-06-01

    Full Text Available The frequent and expanded occurrence of Pyrodinium bahamense var compressum blooms in thePhilippines since 1983 has prompted the need to find mechanisms to control the harmful effects of thesetoxic dinoflagellates. A promising method now being explored is the use of powdered clay mineralswhich when added to the growth media is capable of flocculating with the algal cells. In this study, theefficiency of ball clay, brown bentonite, and Malampaya Sound sediments to remove Pyrodinium cellsin seawater was tested. The addition of 1 g/L of suspended ball clay to 50 mL of cultured Pyrodiniumcells (~1.037 x106 cells/L removed 99.56% of the algal cells after 2.5 hours. Prolonging the exposuretime to 5 and 24 hours showed no significant increase in flocculation. Brown bentonite and MalampayaSound sediments showed low to moderate removal efficiency not exceeding 70% and 50%, respectively.The effect of ball clay addition on seawater chemistry showed no change in ammonia concentration butnitrate decreased after 5 and 24 hours of clay addition. Results for nitrite and phosphate were howevermore variable.

    Climate projections produced with CMIP5 and applied by the Intergovernmental Panel on Climate Change (IPCC) in its fifth assessment report indicate that changes in precipitation and temperature are expected to occur throughout Europe in the 21th century, with a likely decrease of water availability in many regions. Besides, water demand is also expected to increase, in link with these expected climate modifications, but also due to socio-economic and demographic changes. In this respect, the use of future freshwater resources may not be sustainable from the current water management perspective. Therefore adaptation strategies will most likely be needed to cope with these evolutions. In this context, the main objective of the ClimAware project (2010-2013 - www.uni-kassel.de/fb14/wasserbau/CLIMAWARE/, a project implemented within the IWRM-NET Funding Initiative) was to analyse the impacts of climate change (CC) on freshwater resources at the continental and regional scales and to identify efficient adaptation strategies to improve water management for various socio-economic sectors. This should contribute to a more effective implementation of the Water Framework Directive (WFD) and its instruments (river basin management plans, programmes of measures). The project developed integrated measures for improved freshwater management under CC constraints. More specifically, the objectives of the ClimAware project were to: • elaborate quantitative projections of changes in river flows and consequences such as flood frequency, drought occurrence and sectorial water uses. • analyse the effect of CC on the hydromorphological reference conditions of rivers and therefore the definition of "good status". • define management rules/strategies concerning dam management and irrigation practices on different time perspectives. • investigate uncertainties in climate model - scenario combinations.

    Full Text Available Climate change is one of today's most pressing global issues. Policies to guide mitigation and adaptation are needed to avoid the devastating impacts of climate change. The health sector is a significant contributor to greenhouse gas emissions in developed countries, and its climate impact in low-income countries is growing steadily. This paper reviews and discusses the literature regarding health sector mitigation potential, known and hypothetical co-benefits, and the potential of health information technology, such as eHealth, in climate change mitigation and adaptation. The promising role of eHealth as an adaptation strategy to reduce societal vulnerability to climate change, and the link's between mitigation and adaptation, are also discussed. The topic of environmental eHealth has gained little attention to date, despite its potential to contribute to more sustainable and green health care. A growing number of local and global initiatives on ‘green information and communication technology (ICT’ are now mentioning eHealth as a promising technology with the potential to reduce emission rates from ICT use. However, the embracing of eHealth is slow because of limitations in technological infrastructure, capacity and political will. Further research on potential emissions reductions and co-benefits with green ICT, in terms of health outcomes and economic effectiveness, would be valuable to guide development and implementation of eHealth in health sector mitigation and adaptation policies.

  5. Dynamic modelling of water demand, water availability and adaptation strategies for power plants to global change

    International Nuclear Information System (INIS)

    According to the latest IPCC reports, the frequency of hot and dry periods will increase in many regions of the world in the future. For power plant operators, the increasing possibility of water shortages is an important challenge that they have to face. Shortages of electricity due to water shortages could have an influence on industries as well as on private households. Climate change impact analyses must analyse the climate effects on power plants and possible adaptation strategies for the power generation sector. Power plants have lifetimes of several decades. Their water demand changes with climate parameters in the short- and medium-term. In the long-term, the water demand will change as old units are phased out and new generating units appear in their place. In this paper, we describe the integration of functions for the calculation of the water demand of power plants into a water resources management model. Also included are both short-term reactive and long-term planned adaptation. This integration allows us to simulate the interconnection between the water demand of power plants and water resources management, i.e. water availability. Economic evaluation functions for water shortages are also integrated into the water resources management model. This coupled model enables us to analyse scenarios of socio-economic and climate change, as well as the effects of water management actions. (author)

  6. Values under seige in Mexico: strategies for sheltering traditional values from change.

    1993-01-01

    The adverse economic conditions of inflation and falling oil prices over the late 1970s and 1980s in Mexico forced many middle-class married women out of the home and into the workplace in order to help the family maintain its socioeconomic standing. Although this phenomenon ran directly against the traditional Mexican cultural construction of gender and family, many Uruapan middle-class couples had no alternative and rationalized the change by concealing, reinterpreting, or not directly challenging traditional values. Sections discuss the dilemma of middle-class families, Mexican middle-class adaptation to wives' employment, strategies for existing change in values, and the open acceptance of changed values. The author's comments and conclusions are based largely upon interviews with 16 married women of the period. It is concluded that even though the middle class resists them, changes have taken place over the past 20 years in the acceptance of married women in the workplace, the sharing of domestic work, fertility control, and equality between spouses in family decision making. It remains to be seen, however, whether these women will stop working and return to their formerly exclusive roles of wives and mothers if and when economic conditions improve in Mexico.

    2014-03-01

    In this paper, we investigate the modeling and distributed control problems for the load frequency control (LFC) in a smart grid. In contrast with existing works, we consider more practical and real scenarios, where the communication topology of the smart grid changes because of either link failures or packet losses. These topology changes are modeled as a time-varying communication topology matrix. By using this matrix, a new closed-loop power system model is proposed to integrate the communication topology changes into the dynamics of a physical power system. The globally asymptotical stability of this closed-loop power system is analyzed. A distributed gain scheduling LFC strategy is proposed to compensate for the potential degradation of dynamic performance (mean square errors of state vectors) of the power system under communication topology changes. In comparison to conventional centralized control approaches, the proposed method can improve the robustness of the smart grid to the variation of the communication network as well as to reduce computation load. Simulation results show that the proposed distributed gain scheduling approach is capable to improve the robustness of the smart grid to communication topology changes. PMID:24200162

    Recurrent droughts of the last decades have led to severe impacts in forestry and agriculture in the sensitive and vulnerable low-elevation regions of Southeast Europe. Observed impacts are very likely to occur with increasing probability under projected climate conditions throughout the 21st century. In order to suggest options for adaptation and mitigation, a GIS-based Decision Support System is under development in the frame of the joint EU-national research project "Agroclimate". Impact assessments and adaptation support services are based on the simulation results of 12 regional climate models (www.ensembles-eu.org) using the A1B emission scenario until 2100. The development of the Decision Support System requires the balancing of available climatic information and required data for research and economically relevant projection needs of the end users. Here, concrete examples of the development process will be shown for the stepwise analysis and comparison of the followings: 1. Provided climate services: • projected tendencies of temperature and precipitation means and extremes until the end of the 21st century, spread of the simulation results. 2. Required information for climate impact research: • types and characteristics of climate input data, • methods and functions for deriving possible climate change impacts in forestry and agriculture (e.g. on species distribution, growth, production, yield, soil water retention, ground water table, runoff, erosion, evapotranspiration and other ecosystem services and soil properties). 3. Required climate information from the end users' side for developing adaption strategies in the affected sectors: • types of climate indicators, • possible range of the expected impacts (in magnitude and probability). 4. Gaps between climate services and the needs of impact researchers and end users (e.g. spatial and temporal scales, interpretation techniques).

  10. Delivering step change improvements to UK low level waste strategy - 16188

    International Nuclear Information System (INIS)

    The UK Nuclear Industry continues to produce significant quantities of Low Level Waste (LLW) as decommissioning projects generating waste become more prevalent. Current infrastructure and projected increasing waste volumes will deliver a volumetric shortfall of storage capacity in the near future. Recently established as a standalone site licence company, the Low Level Waste Repository (LLWR) near Drigg, in West Cumbria (formerly operated and owned by British Nuclear Group) is tasked with managing the safe treatment and disposal of LLW in the UK, on behalf of the Nuclear Decommissioning Authority (NDA). The problem is complex involving many stakeholders with potentially different priorities. Previously, most nuclear waste generators operated independently with limited integration with other similar organisations. However, the current financial, programme and technical pressures require collaborative working to facilitate a step-change improvement in LLW management. Achieving this quickly is as much of a challenge as delivering robust cost effective technical solutions. NDA is working in partnership with LLWR to develop a LLW Strategy for the Nuclear Industry and has in parallel commissioned a number of studies by the National Nuclear Laboratory (NNL), looking at opportunities to share best practice. A National Strategy Group has been established to develop a working partnership between the Nuclear Decommissioning Authority, LLW Repository Ltd, Regulators, Stakeholders and LLW Consignors, promoting innovation, value for money, and robust implementation of the waste hierarchy (avoid-reduce-re-use-recycle). Additionally the LLWR supported by the NNL have undertaken a comprehensive strategic review of the UK's LLW management activities. Initial collaborative work has provided for the first time a detailed picture of the existing strategic baseline and identified significant national benefits from improving the way LLW is forecasted, characterised, segregated, and

    2013-12-01

    Temporal and spatial changes to the water quality of Dianchi Lake in Southwest China were investigated using monthly monitoring data from 2005 to 2012. Based on the analysis of total phosphorus (TP), total nitrogen (TN), and chlorophyll a (Chl a) concentrations, it was determined that, in Caohai Lake, the annual concentrations of these variables ranged from 0.19-1.46, 6.11-16.79, 0.06-0.14 mg L-1, respectively. In addition, the annual concentrations of TP, TN and Chl a in Waihai Lake ranged between 0.13-0.20, 1.82-3.01, 0.04-0.09 mg L-1, respectively. Cluster Analysis (CA) classified the 10 monitoring sites into two groups (group A and group B) based on similarities of water quality characteristics. Our data revealed that the current status of water quality within Caohai Lake was much worse than that of Waihai Lake. Water quality was seriously degraded during the economic boom near the period of the "Eleventh Five-Year Plan" (2005-2010), and gradually improved from 2010 to 2012 because of the "standard emission directive to industry". The main factors that influenced the spatial and temporal changes to water quality were natural factors including lake evolution and regional characteristic as well as human factors such as pollution load into the lake and management strategies that were already adopted. Some activities and regulations were implemented to enhance the lake environment by controlling wastewater emissions and establishing regulations to protect the lakes in the Yunnan Province. However, problems with institutional fragmentation (horizontal and vertical), simple treatment methods, low-intensity investment in pollution control, and lack of meaningful endogenous pollution control strategies were still present in the lake management strategy. To solve these problems, suitable control measures are needed, especially considering the current old-age status of Dianchi Lake. The fundamental improvement of the water quality within Caohai Lake was dependent on the

  16. Methodology for rehabilitation strategies evaluation aid after an accident: application and results

    International Nuclear Information System (INIS)

    Post-accidental management is a matter for an optimisation process in a multi-criteria context, which has to combine quantitative parameters as well as qualitative parameters. In order to fit with this problematic, a methodological work has been realised at IPSN, in the context of the Becquerel national exercise, which has Simulated a Borax type accident on an experimental reactor. The methodology consists in making a systematic evaluation of indicators in order to provide inter-comparing data for many rehabilitation strategies. Thus, each strategy is evaluated on the one hand in terms of radiological benefit and on the other hand, in terms of incidences such as duration of realisation, materials and human means, workers doses, amount of generated wastes. In this context, calculations highlighted the importance of counter-measures aiming at reducing the external exposure, which is the dominating exposure pathway. The counter-measures aimed at reducing the dose by ingestion lead to a reduction of specific activity are then useful mainly in regard to the limits of commercialization. This work is a first and useful contribution to the clarification of the post-accidental rehabilitation problem. It has also put the light on three important needs: formalization of counter-measures and gathering into a data base, adaptation of calculation tools to make their use easier, and improvement of the knowledge of the operational considerations for the interventions.

    Sustainable land-use planning requires decision makers to balance community growth with resilience to natural hazards. This balance is especially difficult in many coastal communities where planners must grapple with significant growth projections, the persistent threat of extreme events (e.g., hurricanes), and climate-change-driven sea level rise that not only presents a chronic hazard but also alters the spatial extent of sudden-onset hazards such as hurricanes. We examine these stressors on coastal, long-term land-use planning by reporting the results of a one-day community workshop held in Sarasota County, Florida that included focus groups and participatory mapping exercises. Workshop participants reflected various political agendas and socioeconomic interests of five local knowledge domains: business, environment, emergency management and infrastructure, government, and planning. Through a series of alternating domain-specific focus groups and interactive plenary sessions, participants compared the county 2050 comprehensive land-use plan to maps of contemporary hurricane storm-surge hazard zones and projected storm-surge hazard zones enlarged by sea level rise scenarios. This interactive, collaborative approach provided each group of domain experts the opportunity to combine geographically-specific, scientific knowledge on natural hazards and climate change with local viewpoints and concerns. Despite different agendas, interests, and proposed adaptation strategies, there was common agreement among participants for the need to increase community resilience to contemporary hurricane storm-surge hazards and to explore adaptation strategies to combat the projected, enlarged storm-surge hazard zones.

    This study reviews the impacts of climate change on human health and presents corresponding adaptation strategies in South China. The daily mean surface air temperatures above or below 26.4◦C increase the death risk for the people in Guangzhou, especially the elderly are vulnerable to variations in temperature. Heat waves can cause insomnia, fatigue, clinical exacerbation, or death from heatstroke etc., while cold spells show increases in patients with fractures. During a cold spell period, the rates of both on-site emergency rescues and non-implementable rescues increase, and the risk of non-accidental deaths and respiratory disease deaths significantly rise as well. Both time series of hazy days and ozone concentrations have significant positive correlations with the number of patients with cardiovascular diseases. Both malaria and dengue fever reach higher altitudes and mountainous areas due to climate warming. Climate change is likely to bring stronger heat waves in the future, thereby increasing heat wave-related illnesses and deaths, particularly in the metropolitan areas of the Pearl River Delta. The projected increase of continuous cold days in Guangdong province and parts of northern Guangxi province will affect residents’ health in the future. The rising temperature exaggerates ozone pollution, but it is not clear whether climate change is aggravating or mitigating haze pollution. The transmission potential of malaria in South China will increase by 39%-140% and the transmission season will extend by 1-2 months with an air temperature increase of 1-2◦C. By 2050, most areas in Hainan province are projected to convert from non-endemic dengue into endemic dengue areas. The aging population will cause more vulnerable people. To mitigate the adverse impacts of climate change on human health, sound and scientific adaptation strategies must be adopted in advance, such as strengthening the surveillance of epidemic diseases in potential transmission areas

    The laws of microeconomics explain how prices affect consumer purchasing decisions and thus overall revenues and profits. These principles can easily be applied to the behavior aesthetic plastic surgery patients. The UCLA Division of Plastic Surgery resident aesthetics clinic recently offered a radical price change for its services. The effects of this change on demand for services and revenue were tracked. Economic analysis was applied to see if this price change resulted in the maximization of total revenues, or if additional price changes could further optimize them. Economic analysis of pricing involves several steps. The first step is to assess demand. The number of procedures performed by a given practice at different price levels can be plotted to create a demand curve. From this curve, price sensitivities of consumers can be calculated (price elasticity of demand). This information can then be used to determine the pricing level that creates demand for the exact number of procedures that yield optimal revenues. In economic parlance, revenues are maximized by pricing services such that elasticity is equal to 1 (the point of unit elasticity). At the UCLA resident clinic, average total fees per procedure were reduced by 40 percent. This resulted in a 250-percent increase in procedures performed for representative 4-month periods before and after the price change. Net revenues increased by 52 percent. Economic analysis showed that the price elasticity of demand before the price change was 6.2. After the price change it was 1. We conclude that the magnitude of the price change resulted in a fee schedule that yielded the highest possible revenues from the resident clinic. These results show that changes in price do affect total revenue and that the nature of these effects can be understood, predicted, and maximized using the tools of microeconomics. PMID:9950562

  20. More Water Resources but Less for Irrigation: Adaptation Strategy of the Yellow River in a Changing Environment

    The Yellow River is the primary source of freshwater to the northern China. Increasing population and socio-economic development have put great pressure on water resources of the river basin. The anticipated climate and socio-economic changes may further increase water stress. Development of adaptation strategies would have significant implications for water and food security of this region. In this study, the outputs of multiple hydrological models forced with the bias-corrected climatic variables from multiple global climate models were used to assess the change in renewable water resources of the river basin in the 21st century. The outputs of multiple crop models were used to assess the change in agricultural water demand. The domestic and industrial water demands were estimated based on the future socio-economic conditions under the Shared Socio-economic Pathways (SSPs). Besides basic ecosystem needs for water which must be met, the water use in domestic and industrial sectors is considered to have a higher priority than the agricultural water use when water is insufficient. The results show that the renewable water resources of the basin would increase as global mean temperature increases while the water demand would grow much more rapidly, largely due to water demand increase in domestic and industrial sectors. In most of the sub-basins of the Yellow River basin, the available water resources can not sustain all the water use sectors starting from the next a few decades. As more water resources would be appropriated by domestic and industrial sectors, a part of irrigated area had to be converted to rainfed agriculture which led to a large reduction in food production. This study highlights the linked water and food security in a changing environment and suggests that the trade-off should be considered when developing regional adaptation strategies.

  1. The politics of indigeneity: Indigenous strategies for inclusion in climate change negotiations

    Full Text Available Indigenous environmental activists have clearly articulated their views on global climate change policy. The content of these views was explored during the 10-day 2008 World Conservation Congress (WCC in Barcelona. Data were primarily collected through interviews and participant observation. In addition, policy statements and declarations made by indigenous environmental activists from 2000 to 2009 were analysed to place the perspectives of indigenous leaders and environmental activists in the context of their decade-long struggle to gain negotiating power at the United Nations Framework Convention on Climate Change. This study examines the rhetorical strategies indigenous leaders from around the world use to gain political recognition and legitimacy in climate change negotiations. Two core principles, relating to a particular representation of indigenous environmental knowledge are identified as fundamental rhetorical tools. These are a belief that the earth is a living being with rights and the conviction that it is the responsibility of indigenous peoples to protect the earth from over-exploitation. However, reference to indigenous environmental knowledge is not the only rhetorical mechanism used by indigenous leaders in the climate debates. When faced with specific United Nations policies to combat climate change that could have a profound impact on their land rights, some indigenous leaders adopt a more confrontational response. Fearing that new polices would reinforce historical trends of marginalisation, indigenous leaders seeking recognition in climate change debates speak less about their ecological knowledge and responsibility to the earth and more about their shared histories of political and economic marginalisation and land dispossession, experienced first through colonialism and more recently through globalisation.

  2. Integrated Water Management Strategies For The Rhine and Meuse Basins In A Changing Environment

    Water management of the Rhine and Meuse is surrounded by major uncertainties. The central question is then: given the uncertainties, what is the best water management strategy? This raises the need for integrated scenarios that consider possible futures in a coherent and consistent way. Within the framework of IRMA-SPONGE a scenario study was carried out in which physical modelling was combined with socio-cultural theory. Existing climate, land use and socio-economic scenarios, as well as water man- agement strategies have been structured using the Perspectives method. This resulted in integrated scenarios for water management, each representing a different view on the future, together with the according water management style. These were put in a scenario matrix with combinations of world views and management styles, both where these match and mis-match. Using a suite of existing modelling tools the implications of each scenario for the water systems were evaluated. Finally, a comparison of differ- ent water management styles under different possible futures was made, showing the risk, cost and benefits of different strategies.

    Countries in Sub-Saharan Africa are particularly vulnerable to climate change, given dependence on agricultural production and limited adaptive capacity. Based on farm household and Participatory Rural Appraisal data collected from districts in various agroecological zones in Kenya, this paper examines farmers' perceptions of climate change, ongoing adaptation measures, and factors influencing farmers' decisions to adapt. The results show that households face considerable challenges in adapting to climate change. While many households have made small adjustments to their farming practices in response to climate change (in particular, changing planting decisions), few households are able to make more costly investments, for example in agroforestry or irrigation, although there is a desire to invest in such measures. This emphasizes the need for greater investments in rural and agricultural development to support the ability of households to make strategic, long-term decisions that affect their future well-being.

  4. The evolution of competitive settlement strategies in Fijian prehistory : results of excavations and radiometric dating

    International Nuclear Information System (INIS)

    A series of excavations were completed between June 2001 and March 2002 in the Fiji Islands. The goal of this research was to investigate the evolution of competitive settlement strategies in Fijian prehistory from an archaeological and evolutionary ecological perspective. Twelve sites were excavated and mapped in the Sigatoka Valley, located in the southwestern corner of the main island of Viti Levu. Excavations were focused on determining the chronology of fortifications in the region, and the collected samples were compared to expectations based on GIS-based analyses of land productivity and historical documents pertaining to late-period warfare. Over four hundred archaeological sites have been identified in the Sigatoka Valley, and of these roughly one-third are purely defensive in configuration, with no immediate access to water or arable land. The Waikato Archaeological Dating Fund provided four radiometric dates for three defensive sites, and one site associated with a production area. (author). 6 refs., 1 fig

  6. A strategy for the management of milk contaminated as a result of a nuclear accident

    International Nuclear Information System (INIS)

    In the context of nuclear accidents, milk is an important foodstuff because it is produced continually in large quantities. However, the availability of both practical advice and policy level guidance on the management of contaminated milk is limited. This report draws together information on the two strategic approaches that need to be considered: waste minimisation and disposal. Data sheets and decision trees are presented to guide the user through a range of potential management options. The practicability of these options is evaluated against a set of well-established criteria. Unsuitable options are also discussed. Finally, a concise, coherent framework on which to base a broad strategy for the management of contaminated milk is proposed which may be of use to senior government advisers. Recommendations for further work are also made so that any remaining uncertainties can be addressed. (author)

    2012-08-01

    Full Text Available Jakarta is a city with unpredictable yet annual water shortages, both during the dry and wet season, which disproportionately affect the urban poor. One possible solution is to redevelop the existing water supply system which is now working in one of the largest slum area in Penjaringan, North Jakarta. This system is equipped with a large meter, the Master Meter, to record the communal water consumption and individual meters to record household consumptions. The Community Based Organization uses, operates, and maintains the system based on agreement with water users. Improvement of the Master Meter is achieved by harvesting uncollected rain water during the wet season with its high rainfall intensity, modifying the water storage system and improving the influent water quality. This paper aims to provide a preventive strategy in response to climate change and infrastructural failures based on a case study of community-based water supply project in Penjaringan, Jakarta.

    The aim of this study was to evaluate the 6- and 12-month clinical performance of four adhesion strategies from the same manufacturer (Kerr) in non-carious cervical lesions (NCCLs) using two evaluation criteria. Thirty-five patients, with at least four NCCLs each, participated in this study. After samplesize calculation, 180 restorations were assigned to one of the following groups: OFL (Optibond FL), OSP (Optibond Solo Plus), XTR (Optibond XTR), and AIO (Optibond All-In-One). The composite resin Filtek Supreme Ultra (3M ESPE) was placed incrementally. The restorations were evaluated at baseline, after 6 months, and after 12 months, using both the FDI and the USPHS-modified criteria. Statistical analyses were performed with Friedman repeated measures, ANOVA by rank, and the McNemar test for significance in each pair (α=0.05). Six restorations (2 for OFL, 1 for OSP, 2 for XTR, and 1 for AIO) were lost at 12 months (P>0.05 for both evaluation criteria). Marginal staining was observed in seven restorations using the FDI criteria (P>0.05) and three restorations using the USPHSmodified criteria (P>0.05). Eight restorations (2 for OSP, 3 for XTR, and 3 for AIO) were classified as Bravo for marginal adaptation using the USPHSmodified criteria (P>0.05). However, 62 restorations (14 for OFL, 12 for OSP, 15 for XTR, and 21 for AIO) were classified as Bravo using the FDI criteria (P>0.05). The four adhesion strategies showed similar clinical retention at 6 and 12 months. The FDI evaluation criteria tend to be more sensitive than the USPHS-modified criteria. PMID:25625130

    Changes in land use and combustion of fossil fuels have been largest human impact on the global carbon cycle and without a complete accounting of net greenhouse-gas (GHG) fluxes, developing and evaluating adaptation strategies are not possible. The major source of GHG fluxes associated with crop production are soil N2O emissions, soil CO2 and methane (CH4) fluxes, and CO2 emission associated with agricultural inputs and farm equipment operation. This study points out the main principles which are at the base of solar energy use for sustainability of irrigated agriculture. Field tests were carried out in order to compare crop yield and solar pump plant performance, for the photovoltaic conversion of solar energy, connected to drip irrigation and sprinkler system plants during the irrigation season. The system mainly consists of the parts listed here: set of flat photovoltaic panels consisting of 150 panels for a total of 3000 W peak value once installed, connected in serial-parallel to obtain a 120 Vdc operating voltage rating. The panels utilize 36 serially connected single-crystal silicon cells providing a 12 V voltage rating. The serial connection of 10 panels generates the system's operating voltage rating (120 Vdc). The total 3000 W peak value power is obtained by connecting in parallel 15 serial-strings. When the circuit is open, the voltage at the ends of the panels can reach 210 Volts. The photovoltaic system supplies, through an inverter, a three-phase 1.6 kW canned pump located in the artesian well. The relevant hydraulic line connects this pump to the various utilities. The hydraulic capacity of the helium pump has been used during the irrigation season in order to meet the water needs of a corn crop. Therefore, along with the solar pump was used a dispersing wing type drip irrigation system with double chamber hosing (70 kPa operating pressure), with external holes spaced 0.3 m apart, 0.75 m distance between the wings, wing length 120 m and placed

    This paper analyzes the climate change impact on water diversion plan of Melamchi Water Supply Project (MWSP) in Nepal. The MWSP is an interbasin water transfer project aimed at diverting water from the Melamchi River of the Indrawati River basin to Kathmandu Valley for drinking water purpose. Future temperature and precipitation of the basin were predicted using the outputs of two regional climate models (RCMs) and two general circulation models (GCMs) under two representative concentration pathway (RCP) scenarios which were then used as inputs to Soil and Water Assessment Tool (SWAT) to predict the water availability and evaluate the water diversion strategies in the future. The average temperature of the basin is projected to increase by 2.35 to 4.25 °C under RCP 4.5 and RCP 8.5, respectively, by 2085s. The average precipitation in the basin is projected to increase by 6-18 % in the future. The annual water availability is projected to increase in the future; however, the variability is observed in monthly water availability in the basin. The water supply and demand scenarios of Kathmandu Valley was also examined by considering the population increase, unaccounted for water and water diversion from MWSP in the future. It is observed that even with the additional supply of water from MWSP and reduction of unaccounted for water, the Kathmandu Valley will be still under water scarcity in the future. The findings of this study can be helpful to formulate water supply and demand management strategies in Kathmandu Valley in the context of climate change in the future.

    2000-05-01

    This power point presentation included information about the Kyoto Protocol and discussed how Canada will address the challenge of this important global issue. The national process by which Canada and each province will begin implementation of options was described. The presentation also discussed the international context on the Kyoto Challenge, the development of a strategy and the role of the Climate Change Action Fund (CCAF) in the 2000 Federal Budget. The two major objectives of the CCAF are to build the foundation for the development of a national implementation strategy and to initiate early action through the $150 million in contributions from government, private sector and other interested parties over the next 3 years. Charts depicting Canada's carbon dioxide emissions projections and the Kyoto target indicate that under a business as usual scenario, carbon dioxide emissions would reach 764 Mt by 2010. If the Kyoto target of 6 per cent below 1990 levels is achieved, those emissions would be 26 per cent lower or the equivalent of 565 Mt. The projected increases of greenhouse gas (GHG) emissions from 1990 to 2010 by sector were also presented according to residential, commercial, industrial, transportation, electricity generation, fossil fuel production, agroecosystems and other non-energy sectors. It is forecasted that the transportation sector will account for the highest contribution to GHG emissions. The largest increase from 1990 levels will be seen in the fossil fuel production sector. Similar charts were presented for GHG emissions by province. A total of 69 projects have been initiated involving CCAF contributions. Funding has been provided in support of climate model improvements, studies of GHG sources and sinks as well as ocean and arctic research. Other studies included the impacts of climate change on crop yield variability, permafrost degradation, sea level rise, forest fire incidence, marine growth, water quality and forest health. 7

    Climate change affects the productivity of agricultural ecosystems. Farmers cope with climate change based on their perceptions of changing climate patterns. Using a case study from the Middle Yarlung Zangbo River Valley, we present a new research framework that uses questionnaire and interview methods to compare local farmers' perceptions of climate change with the adaptive farming strategies they adopt. Most farmers in the valley believed that temperatures had increased in the last 30 years but did not note any changes in precipitation. Most farmers also reported sowing and harvesting hulless barley 10-15 days earlier than they were 20 years ago. In addition, farmers observed that plants were flowering and river ice was melting earlier in the season, but they did not perceive changes in plant germination, herbaceous vegetation growth, or other spring seasonal events. Most farmers noticed an extended fall season signified by delays in the freezing of rivers and an extended growing season for grassland vegetation. The study results showed that agricultural practices in the study area are still traditional; that is, local farmers' perceptions of climate change and their strategies to mitigate its impacts were based on indigenous knowledge and their own experiences. Adaptive strategies included adjusting planting and harvesting dates, changing crop species, and improving irrigation infrastructure. However, the farmers' decisions could not be fully attributed to their concerns about climate change. Local farming systems exhibit high adaptability to climate variability. Additionally, off-farm income has reduced the dependence of the farmers on agriculture, and an agricultural subsidy from the Chinese Central Government has mitigated the farmers' vulnerability. Nevertheless, it remains necessary for local farmers to build a system of adaptive climate change strategies that combines traditional experience and indigenous knowledge with scientific research and government

  15. Review of low-energy construction, air tightness, ventilation strategies and indoor radon: results from Finnish houses and apartments

    International Nuclear Information System (INIS)

    Low-energy and passive house construction practices are characterised by increased insulation, high air tightness of the building shell and controlled mechanical ventilation with heat recovery. As a result of the interaction of mechanical ventilation and high air tightness, the pressure difference in a building can be markedly enhanced. This may lead to elevated indoor radon levels. Minor leakages in the foundation can affect the radon concentration, even in the case where such leaks do not markedly reduce the total air tightness. The potential for high pressures to affect indoor radon concentrations markedly increases when the air tightness ACH50, i.e. the air change per hour induced by a pressure difference of 50 Pa, is -1. Pressure differences in Finnish low-rise residential houses having mechanical supply and exhaust ventilation with heat recovery (MSEV) are typically 2-3 Pa, clearly lower than the values of 5-9 Pa in houses with only mechanical exhaust ventilation (MEV). In MSEV houses, radon concentrations are typically 30 % lower than in MEV houses. In new MSEV houses with an ACH50 of 0.6 h-1, the limit for passive construction, the analytical estimates predict an increase of 100 % in the radon concentration compared with older houses with an ACH50 of 4.0 h-1. This poses a challenge for efficient radon prevention in new construction. Radon concentrations are typically 30 % lower in houses with two storeys compared with only one storey. The introduction of an MSEV ventilation strategy in typically very airtight apartments has markedly reduced pressure differences and radon concentrations. (authors)

  16. A strategy for repairing pectus excavatum and long-term results

    International Nuclear Information System (INIS)

    Our strategy for repairing pectus excavatum is based on the Nuss procedure regarding the use of a bending pectus bar, and we have modified the procedure to create a bar tunnel extrapleurally using an endoscope. We use two methods for pectus repair. One is a modified Nuss procedure, designated the MN method, which we use for prepubescent patients if the force required to elevate the end of the sternum after detachment of the xiphoid process from the sternum through an incision at the deepest point of the depression is 4 kg or having severe asymmetrical shapes. The EA method includes costal cartilage resection to reduce the resistance to sternal elevation and allow repair of asymmetrical depressions. We performed the MN method on 31 patients and the EA method on 26 patients. We experienced no infections, pericarditis, hemothorax, persistent pain, or cardiovascular complications. We performed long-term follow-up of ≥6 months (6-88.3 months) after bar removal for 25 MN cases and 10 EA cases using the CT index. The CT indexes for the early period after bar removal and the long-term period did not differ significantly for both methods. Although our methods for pectus repair require more time than the original Nuss procedure, we believe that they are safer and more flexible for various types and ages of pectus excavatum. (author)

    Reaping the optimal rewards from any quality improvement project mandates sustainability after the initial implementation. In Part III of this three-part ATS Seminars series, we discuss strategies to create a culture for change, improve cooperation and interaction between multidisciplinary teams of clinicians, and position the intensive care unit (ICU) optimally within the hospital environment. Coaches are used throughout other industries to help professionals assess and continually improve upon their practice; use of this strategy is as of yet infrequent in health care, but would be easily transferable and potentially beneficial to ICU managers and clinicians alike. Similarly, activities focused on improving teamwork are commonplace outside of health care. Simulation training and classroom education about key components of successful team functioning are known to result in improvements. In addition to creating an ICU environment in which individuals and teams of clinicians perform well, ICU managers must position the ICU to function well within the hospital system. It is important to move away from the notion of a standalone ("siloed") ICU to one that is well integrated into the rest of the institution. Creating a "pull-system" (in which participants are active in searching out needed resources and admitting patients) can help ICU managers both provide better care for the critically ill and strengthen relationships with non-ICU staff. Although not necessary, there is potential upside to creating a unified critical care service to assist with achieving these ends. PMID:24601653

  18. Efficient local behavioral change strategies to reduce the spread of epidemics in networks

    CERN Document Server

    Bu, Yilei; Mills, Harriet L

    2013-01-01

    It has recently become established that the spread of infectious diseases between humans is affected not only by the pathogen itself but also by changes in behavior as the population becomes aware of the epidemic; for example, social distancing. It is also well known that community structure (the existence of relatively densely connected groups of vertices) in contact networks influences the spread of disease. We propose a set of local strategies for social distancing, based on community structure, that can be employed in the event of an epidemic to reduce the epidemic size. Unlike most social distancing methods, ours do not require individuals to know the disease state (infected or susceptible, etc.) of others, and we do not make the unrealistic assumption that the structure of the entire contact network is known. Instead, the recommended behavior change is based only on an individual's local view of the network. Each individual avoids contact with a fraction of his/her contacts, using knowledge of his/her l...

    Although changes in brain function induced by cognitive training have been examined, functional plasticity associated with specific training strategies is still relatively unexplored. In this study, we examined changes in brain function during a complex visuomotor task following training using the Space Fortress video game. To assess brain function, participants completed functional magnetic resonance imaging (fMRI) before and after 30 h of training with one of two training regimens: Hybrid Variable-Priority Training (HVT), with a focus on improving specific skills and managing task priority, or Full Emphasis Training (FET), in which participants simply practiced the game to obtain the highest overall score. Control participants received only 6 h of FET. Compared to FET, HVT learners reached higher performance on the game and showed less brain activation in areas related to visuo-spatial attention and goal-directed movement after training. Compared to the control group, HVT exhibited less brain activation in right dorsolateral prefrontal cortex (DLPFC), coupled with greater performance improvement. Region-of-interest analysis revealed that the reduction in brain activation was correlated with improved performance on the task. This study sheds light on the neurobiological mechanisms of improved learning from directed training (HVT) over non-directed training (FET), which is related to visuo-spatial attention and goal-directed motor planning, while separating the practice-based benefit, which is related to executive control and rule management.

    The Mesoamerican region is considered to be one of the areas in the world most vulnerable to climate change. We developed a framework for quantifying the vulnerability of the livelihoods of coffee growers in Mesoamerica at regional and local levels and identify adaptation strategies. Following the Intergovernmental Panel on Climate Change (IPCC) concepts, vulnerability was defined as the combination of exposure, sensitivity and adaptive capacity. To quantify exposure, changes in the climatic ...

    2009-04-01

    Based on the TERENO infrastructure, SoilCan (Soil can make a difference in climate policy) is designed as a long-term large scale experiment to study the effects of land use changes of terrestrial systems caused by Global Change. The soil and ground water, in particular the water and matter fluxes in soil, are the main focuses of SoilCan. Primary objectives of SoilCan are: • Further development of the instrumentation of the TERENO-observatories to study the effects of land use changes on soils • Collection of comprehensive long-term data to monitor Global Change on the regional scale • Provision of high-quality data to develop and improve the prognosis of regional climate models with the aim to develop and implement options for management strategies. In the frame of SoilCan, fully automated lysimeter systems will be installed on several highly equipped experimental field sites of the TERENO-observatories and the relevant status variables of each ecosystem will be monitored (e.g. climate, hydrology, biosphere-atmosphere exchange, biodiversity, etc.). The TERENO-observatories are placed in four different regions of Germany: • "Rur" observatory - moderate atlantic climate • "Ammer" observatory - alpine climate • "Bode" observatory - continental climate • "Müritz" observatory - baltic climate The field sites will have a radio-based technology for automatic monitoring and data communication. In total, 90 lysimeters (1.5 m depth, 1m2 surface) will be filled with soil monoliths at the four TERENO-observatories. The lysimeters will be partly transplanted along the existing natural temperature and rainfall gradients. The transplantation of lysimeters inside an observatory as well as between the four different observatories is of utmost importance for SoilCan. In case of the "Rur" observatory, three intensively instrumented field sites ("Wüstebach", "Rollesbroich" und "Selhausen") will be equipped with lysimeter stations. Along with a temperature and rainfall

    2013-12-01

    Full Text Available Over the last four decades, the clothing industry has seen one of the most radical, global transformations of any industry, and Western European clothing companies have been put under strain. To the surprise of industry observers and academics, however, Denmark continues to hold expansive and profitable companies within this industry. Both the trade itself and industry observers see the present success of Danish fashion as the result of Danish pioneering in international outsourcing. The article challenges the commonly told story, arguing that the present success should be seen as the result of new companies entering the sector rather than the transformation of old ones. The article demonstrates that value chain strategies are constantly in the making and successful ones rarely remain competitive for long.

    Full Text Available MetaSearch is utilizing multiple other search systems to perform simultaneous search. A MetaSearch Engine (MSE is a search system that enables MetaSearch. To perform a MetaSearch, user query is sent to multiple search engines; once the search results returned, they are received by the MSE, then merged into a single ranked list and the ranked list is presented to the user. When a query is submitted to a MSE, decisions are made with respect to the underlying search engines to be used, what modifications will be made to the query and how to score the results. These decisions are typically made by considering only the user€™s keyword query, neglecting the larger information need. The cornerstone of their technology is their rank aggregation method. In other words, Result merging is a key component in a MSE. The effectiveness of a MSE is closely related to the result merging algorithm it employs. In this paper, we want to investigate a variety of result merging methods based on a wide range of available information about the retrieved results, from their local ranks, their titles and snippets, to the full documents of these results.

  8. Responses to climate and economic risks and opportunities across national and ecological boundaries: changing household strategies on the Mongolian plateau

    International Nuclear Information System (INIS)

    Climate changes on the Mongolian Plateau are creating new challenges for the households and communities of the region. Much of the existing research on household choices in response to climate variability and change focuses on environmental risks and stresses. In contrast, our analysis highlights the importance of taking into account environmental and economic opportunities in explaining household adaptation choices. We surveyed over 750 households arrayed along an ecological gradient and matched across the national border in Mongolia and the Inner Mongolia Autonomous Region, China, asking what changes in livelihoods strategies households made over the last ten years, and analyzed these choices in two broad categories of options: diversification and livestock management. We combined these data with remotely sensed information about vegetation growth and self-reported exposure to price fluctuations. Our statistical results showed that households experiencing lower ecological and economic variability, higher average levels of vegetation growth, and with greater levels of material wealth, were often those that undertook more actions to improve their conditions in the face of variability. The findings have implications both for how interventions aimed at supporting ongoing choices might be targeted and for theory construction related to social adaptation. (letter)

    Full Text Available Abstract Background A sound understanding of malaria transmission patterns in the People’s Republic of China (P.R. China is crucial for designing effective surveillance-response strategies that can guide the national malaria elimination programme (NMEP. Using an established biology-driven model, it is expected that one may design and refine appropriate surveillance-response strategies for different transmission zones, which, in turn, assist the NMEP in the ongoing implementation period (2010–2020 and, potentially, in the post-elimination stage (2020–2050. Methods Environmental data obtained from 676 locations across P.R. China, such as monthly temperature and yearly relative humidity (YRH, for the period 1961–2000 were prepared. Smoothed surface maps of the number of months suitable for parasite survival derived from monthly mean temperature and YRH were generated. For each decade, the final malaria prediction map was overlaid by two masked maps, one showing the number of months suitable for parasite survival and the other the length of YRH map in excess of 60%. Results Considering multiple environmental factors simultaneously, the environmental variables suitable for malaria transmission were found to have shifted northwards, which was especially pronounced in northern P.R. China. The unstable suitable regions (transmission periods between five and six months showed increased transmission intensity due to prolonged suitable periods, especially in the central part of the country. Conclusion Adequate and effective surveillance-response strategies for NMEP should be designed to achieve the goal of malaria elimination in P.R. China by 2020, especially in the zones predicted to be the most vulnerable for climate change.

    Dramatic changes due to climate and land use dynamics in the Mongolian Plateau affecting ecosystem services and agro-pastoral systems in Mongolia. Recently, market forces and development strategies are affecting land and water resources of the pastoral communities which are being further stressed due to climatic changes. Evaluation of pastoral systems, where humans depend on livestock and grassland ecosystem services, have demonstrated the vulnerability of the social-ecological system to climate change. Current social-ecological changes in ecosystem services are affecting land productivity and carrying capacity, land-atmosphere interactions, water resources, and livelihood strategies. The general trend involves greater intensification of resource exploitation at the expense of traditional patterns of extensive range utilization. Thus we expect climate-land use-land cover relationships to be crucially modified by the social-economic forces. The analysis incorporates information about the social-economic transitions taking place in the region which affect land-use, food security, and ecosystem dynamics. The region of study extends from the Mongolian plateau in Mongolia. Our research indicate that sustainability of pastoral systems in the region needs to integrate the impact of climate change on ecosystem services with socio-economic changes shaping the livelihood strategies of pastoral systems in the region. Adaptation strategies which incorporate integrated analysis of landscape management and livelihood strategies provides a framework which links ecosystem services to critical resource assets. Analysis of the available livelihood assets provides insights to the adaptive capacity of various agents in a region or in a community. Sustainable development pathways which enable the development of these adaptive capacity elements will lead to more effective adaptive management strategies for pastoral land use and herder's living standards. Pastoralists will have the

    Little is known about dissemination strategies that contribute to health information recognition. This study examined (a) health campaign exposure and awareness (slogan and logo recognition); (b) perceived communication channels; (c) differences between perceptions of researcher-developed and enhancement community health information materials; and (d) differences in campaign awareness and communication channels, according to Japanese community demographic characteristics. A cross-sectional survey (N = 508) was conducted in Tokigawa, Japan, in 2013. The Small Change Campaign focused on increasing physical activity and improving dietary habits. Information dissemination was carried out using leaflets, newsletters, posters, website, local public relations magazines, health classes, events, and online newsletters. The participants completed a survey assessing their campaign awareness (i.e., slogan and logo) and exposure to the informational materials presented during the campaign. Fewer than half (45.4%) knew the slogan, and only 24.4% were aware of the logo. Public relations magazines, leaflets, and newsletters were significantly better-perceived health communication channels. Researcher-developed and enhancement community health information materials were equally recognized (p = .34, w = .08). Furthermore, women and those who were employed were significantly more aware of the slogan, logo, and communication materials. Further research should explore effective communication strategies for community-based health promotion intervention via randomized control trials. PMID:25869407

    Managerial decision making is likely to be a dominant determinant of performance of teams in team sports. Here we use Japanese and German football data to investigate correlates between temporal patterns of formation changes across matches and match results. We found that individual teams and managers both showed win-stay lose-shift behavior, a type of reinforcement learning. In other words, they tended to stick to the current formation after a win and switch to a different formation after a loss. In addition, formation changes did not affect the results of succeeding matches in most cases. The results indicate that a swift implementation of a new formation in the win-stay lose-shift manner may not be a successful managerial rule of thumb.

    2014-05-01

    Climate change is driven by global processes such as the global ocean circulation and its variability over time leading to changing weather patterns on regional scales as well as changes in the severity and occurrence of extreme events such as heat waves. For example, the summer 2003 European heat wave caused up to 70.000 excess deaths over four months in Central and Western Europe. As around 75% of Europe's population resides in urban areas, it is of particular relevance to examine the impact of seasonal to decadal-scale climate variability on urban areas and their populations. This study aims at downscaling the spatially coarse resolution CMIP5 climate predictions to the local urban scale and investigating the relation between heat waves and the urban-rural temperature increment (urban heat island effect). The resulting heat stress effect is not only driven by climatic variables but also impacted by urban morphology. Moreover, the exposure varies significantly with the geographical location. All this information is coupled with relevant socio-economic datasets such as population density, age structure, etc. focussing on human health. The analyses are conducted in the framework of the NACLIM FP7 project funded by the European Commission involving local stakeholders such as the cities of Antwerp (BE), Berlin (DE) and Almada (PT) represented by different climate and urban characteristics. The end-user needs have been consolidated in a climate services plan including the production of heat risk exposure maps and the analysis of various scenarios considering e.g. the uncertainty of the global climate predictions, urban expansion over time and the impact of mitigation measures such as green roofs. The results of this study will allow urban planners and policy makers facing the challenges of climate change and develop sound strategies for the design and management of climate resilient cities.

  18. Nursing entrepreneurship: motivators, strategies and possibilities for professional advancement and health system change.

    Science.gov (United States)

    Wall, Sarah

    2013-06-01

    In Canada, as well as internationally, efficiency-focused organizational restructuring in healthcare has resulted in stressful job change for nurses, although nurses continue to work in a system that values technology-based, physician-provided services. Employed nurses have had to participate in organizational activities that undermine their professional values and goals. Nursing entrepreneurship presents an opportunity to explore nursing's professional potential in nursing practice that is uniquely independent. In this study, a focused ethnographic approach was used to explore the experiences of self-employed nurses, who see themselves as leaders in advancing the profession of nursing and its contribution to healthcare. Key themes in the findings include the responses of self-employed nurses to health system change, expanded roles for nurses, the consequences of this non-traditional approach to nursing work and the possibilities for change that arise from nursing entrepreneurship. This research has implications for healthcare policy, professional advocacy and nursing education. PMID:23809640

    Chang'E-1 lunar Orbiter was launched by Long March 3A rocket from Xichang Satellite Launch Center at 18:05 BT (Beijing Time) Oct. 24, 2007. It is the first step of its ambitious three-stage moon program, a new milestone in the Chinese space exploration history. The primary science objectives of Chang'E-1 lunar orbiter are to obtain three-Dimension (3D) stereo images of the lunar surface, to analyze the distribution and abundance of elements on the surface, to investigate the thickness of lunar soil, evaluate helium-3 resources and other characteristics, and to detect the space environment around the moon. To achieve the above four mission objectives, eight sets of scientific instruments are chosen as the payloads of the lunar orbiter, including a CCD stereo camera (CCD), a Sagnac-based interferometer spectrometer (IIM), a Laser Altimeter (LAM), a Microwave Radiometer (MRM), a Gamma-Ray Spectrometer (GRS), an X-ray spectrometer (XRS), a High-Energy Particle Detector (HPD), and two Solar Wind Ion Detectors (SWID). The detected data of the payloads show that all payloads work well. This paper introduces the status of payloads in the first phase and preliminary scientific results.

    The all-silicon design of the CMS tracker poses new challenges in aligning the system with more than 15,000 independent modules. For optimal track-parameter resolution, the position and orientation of its modules need to be determined with a precision of better than few dozens of micrometres. Starting with the survey measurements and corrections provided by the hardware alignment system, the ultimate precision can be achieved with data from the silicon modules traversed in-situ by charged particles. Several implementations of statistical algorithms allow to solve the optimization problem with the required accuracy in manageable time. Survey measurements and experience with the hardware alignment system are described as well as the selection of data samples used for track based alignment and results from Monte-Carlo studies. First CMS Tracker alignment analysis results with cosmic track data are given.

    Full Text Available Introduction: The eponym “Monteggia fracture” includes various patterns of complex fracture-dislocations of the proximal ulna and radius, which are not well defined yet. They are frequently described as Monteggia-like lesions or Monteggia equivalent injuries. Until today, these injury patterns have been reported rarely. The objective of this retrospective study was to better define patterns of injury and to document the short-term results of treatment with current fixation techniques.Methods: Ten patients with a Monteggia-like lesion were included in this study and clinical and radiological follow-up examinations at an average of 12.3 months after the trauma were performed. For clinical follow-up the Mayo Modified Wrist Score, the Mayo Elbow Performance Score, the functional rating index of Broberg and Morrey, and the DASH score were utilized.Results: Osteosynthesis of the ulna was performed using a proximally contoured or precontoured LCP (locking compression plate in all patients. All patients had a fracture of the radial head. All patients with a Mason type III radial head fracture received a cemented bipolar radial head prosthesis. All Mason type II fractures were treated with open reduction and internal fixation using mini screws. In all Mason type I fractures the treatment of the radial head dislocation was by closed reduction. Associated coronoid fractures were stabilized with lag screws through the ulnar plate or with independent lag screws after reduction of the fracture. According to the aforementioned scoring systems good to excellent results could be achieved.Conclusions: Our findings demonstrate that good or excellent short-term results can be obtained if the injury is classified correctly and a standardized surgical treatment of all components of the injury is achieved. Further studies with larger patient populations and longer follow up periods are needed to evaluate long-term effectiveness of this treatment concept.

  6. Livestock in a changing climate: production system transitions as an adaptation strategy for agriculture

    International Nuclear Information System (INIS)

    Livestock farming is the world’s largest land use sector and utilizes around 60% of the global biomass harvest. Over the coming decades, climate change will affect the natural resource base of livestock production, especially the productivity of rangeland and feed crops. Based on a comprehensive impact modeling chain, we assess implications of different climate projections for agricultural production costs and land use change and explore the effectiveness of livestock system transitions as an adaptation strategy. Simulated climate impacts on crop yields and rangeland productivity generate adaptation costs amounting to 3% of total agricultural production costs in 2045 (i.e. 145 billion US$). Shifts in livestock production towards mixed crop-livestock systems represent a resource- and cost-efficient adaptation option, reducing agricultural adaptation costs to 0.3% of total production costs and simultaneously abating deforestation by about 76 million ha globally. The relatively positive climate impacts on grass yields compared with crop yields favor grazing systems inter alia in South Asia and North America. Incomplete transitions in production systems already have a strong adaptive and cost reducing effect: a 50% shift to mixed systems lowers agricultural adaptation costs to 0.8%. General responses of production costs to system transitions are robust across different global climate and crop models as well as regarding assumptions on CO2 fertilization, but simulated values show a large variation. In the face of these uncertainties, public policy support for transforming livestock production systems provides an important lever to improve agricultural resource management and lower adaptation costs, possibly even contributing to emission reduction.

Shifts in livestock production towards mixed crop-livestock systems represent a resource- and cost-efficient adaptation option, reducing agricultural adaptation costs to 0.3% of total production costs and simultaneously abating deforestation by about 76 million ha globally. The relatively positive climate impacts on grass yields compared with crop yields favor grazing systems inter alia in South Asia and North America. Incomplete transitions in production systems already have a strong adaptive and cost reducing effect: a 50% shift to mixed systems lowers agricultural adaptation costs to 0.8%. General responses of production costs to system transitions are robust across different global climate and crop models as well as regarding assumptions on CO2 fertilization, but simulated values show a large variation. In the face of these uncertainties, public policy support for transforming livestock production systems provides an important lever to improve agricultural resource management and lower adaptation costs, possibly even contributing to emission reduction.

  8. New perception of childhood as a result of changing gender roles

    2014-01-01

    Gender roles are a result and reflection of social change. Owing to gender equality, women are rising to prominence in the area of work, which is one of the significant factors influencing the formation of gender roles. We can observe men slowly entering the private sphere where they are involved in activities limited to taking care of their children. Nevertheless, the asymmetry between the genders persists in both public and private life; the situation has not changed dramatically. However, ...

  9. Designing environmental campaigns by using agent-based simulations: strategies for changing environmental attitudes.

    Mosler, Hans-Joachim; Martens, Thomas

    2008-09-01

    Agent-based computer simulation was used to create artificial communities in which each individual was constructed according to the principles of the elaboration likelihood model of Petty and Cacioppo [1986. The elaboration likelihood model of persuasion. In: Berkowitz, L. (Ed.), Advances in Experimental Social Psychology. Academic Press, New York, NY, pp. 123-205]. Campaigning strategies and community characteristics were varied systematically to understand and test their impact on attitudes towards environmental protection. The results show that strong arguments influence a green (environmentally concerned) population with many contacts most effectively, while peripheral cues have the greatest impact on a non-green population with fewer contacts. Overall, deeper information scrutiny increases the impact of strong arguments but is especially important for convincing green populations. Campaigns involving person-to-person communication are superior to mass-media campaigns because they can be adapted to recipients' characteristics. PMID:17548145

  10. Learning about frequency on the fly: Recent experience changes strategies regarding linguistic frequency in recognition memory.

    Science.gov (United States)

    Miller, Jeremy K

    2010-01-01

    In the present study, the author examines whether participants can adjust recognition response strategies to account for the effects of linguistic frequency. Experiment 1 used a counterfeit-list technique to replicate findings that indicate that participants exhibit a bias toward choosing high-frequency lures. Experiment 2 demonstrates that when participants are exposed to a training phase that includes an opportunity to recognize high- and low-frequency words, participants no longer demonstrate a significant bias toward choosing high-frequency items on the counterfeit list task. Experiments 3 and 4 examine how participants learn to adjust for linguistic frequency by manipulating the information available during training. The results demonstrate that participants use information from the training phase indicating that high word frequency is a good cue to oldness to guide their memory decisions during the counterfeit list task, but do not use training phase information indicating that low frequency is the best cue to oldness in a similar fashion.

  11. Dynamics of the European refining and petrochemical industry. Strategies, structure and change

    International Nuclear Information System (INIS)

    The changes in the market position of producers engaged in the oil refining and basic petrochemical industry on the Western European market are the central theme of this book. Analysis of this reshuffling process among these actors is conducted on three levels. First, research is carried out at the level of world regions. In order to understand the reorganization of oil refining and basic petrochemical production in Western Europe, it is necessary to explore the recent aggregate dynamics of these activities on a global scale. Second, the differences in strategic behaviour are exanuned at the level of groups of market participants, namely the major oil companies, the chemical companies, the state-owned companies from both consumer and producer countries, and the independents. Finally, the investment/disinvestment decisions in the Western European oil refining and basic petrochemical industry are investigated at the level of the individual firm. Particular emphasis is placed upon explaining why companies active in the sectors under study have followed different strategies, although they have been confronted with similar adverse market conditions in Western Europe during the last decades. 341 refs

  12. The scope and impact of obesity in Vermont - Strategies for change.

    Science.gov (United States)

    Chen, Harry L

    2015-11-01

    Obesity is a complex, multi-faceted condition amplified by a confluence of socio-economic and environmental forces. Even in Vermont, a state long ranked as one of the healthiest, 25% of adults are obese, a rate better than 44 other states, but more than double that in 1990. Obesity puts people at greater risk for a number of serious health conditions, and may soon overtake tobacco as the #1 real killer if the current trend is not reversed. Beyond the cost to an individual's health, the projected financial impacts of an increasingly obese population are great. Nationally, the estimated direct and indirect costs of obesity add up to more than $190 billion each year. In public health terms, the challenge we are facing with obesity can well be compared to our experience with tobacco. We can easily track advances in policy, counter-marketing and other changes that together have created an environment in which smoking is no longer the norm. The Vermont Department of Health is beginning to apply strategies similar to those used to successfully cut smoking rates. This commentary describes Vermont's efforts to increase physical activity, decrease caloric intake, and enlist partners to help make healthy choices easier and more accessible for everyone.

However, the scarcity of organs appropriate for transplantation has led to an organ shortage crisis. This article retrospectively reviews strategies to change negative public attitudes toward organ donation in the People's Republic of China. We strongly believe that efforts to publicize knowledge of organ donation, promote family discussions, train medical staff and students, establish incentive systems, and implement regulatory oversight may combat unfavorable Chinese public opinion toward organ donation and transplantation, thus potentially increasing the organ donation rate in the People's Republic of China.

  16. A mm-Wave Polarisation Analyser Using LEKIDs: Strategy and Preliminary Numerical Results

    2014-08-01

    The context of this study is the development of polarisation sensitive detectors in view of future Cosmic Microwave Background experiments. Our goal is to demonstrate the possibility to make a mm-wave polarisation analyser at 150 GHz using Lumped Element Kinetic Inductance Detectors (LEKIDs). Although LEKIDs are very attractive for the relative ease of fabrication, they have an intrinsic optical response which is weakly polarisation-senstive, i.e. orthogonal linear polarisations are absorbed with comparable efficiencies (with a separation typically not exceeding few dB). To overcome this difficulty, we achieve a polarised response by means of small () superconducting Nb wire-grids. Each grid is deposited on the rear side of the 300 micron Si substrate, on which 20 nm Al resonators are patterned, so that each pixel may in principle respond as an independent polarisation analyser. Simulations show encouraging results, with a deep (-20 dB) rejection of the unwanted polarisation. Although what we present here is not yet a polarimeter, this pilot study allows us to address some relevant questions that may be crucial in view of a full polarimetric architecture development. In particular, our first prototypes will allow to assess the behaviour of small grids, the interaction between adjacent polarised pixels, and to choose the most suitable resonator geometry. What we present here are preliminary design results about devices which are currently being realised, and soon ready for optical response characterisation.

  17. Climate change adaptation via targeted ecosystem service provision: a sustainable land management strategy for the Segura catchment (SE Spain)

    Science.gov (United States)

    Zagaria, Cecilia; de Vente, Joris; Perez-Cutillas, Pedro

    2014-05-01

    Topical research investigating climate, land-use and management scenarios in the Segura catchment (SE Spain), depicts a landscape at high-risk of, quite literally, deserting agriculture. Land degradation in the semi-arid region of SE Spain is characterized by water shortage, high erosion rates and salinization, increasingly exacerbated by climatic changes, scarce vegetation cover and detrimental farming practices. Future climate scenarios predict increases in aridity, variability and intensity of rainfall events, leading to increasing pressure on scarce soil and water resources. This study conceptualized the impending crisis of agro-ecological systems of the Segura basin (18800 km2) as a crisis of ecosystem service deterioration. In light of existing land degradation drivers and future climate scenarios, the potential of Sustainable Land Management (SLM) strategies was evaluated to target three priority ecosystem services (water provision, sediment retention and carbon sequestration) as a means to achieve climate change adaptation and mitigation. A preceding thorough process of stakeholder engagement (as part of the EU funded DESIRE project) indicated five SLM technologies for potential implementation, all with a focus upon reducing soil erosion, increasing soil water holding capacity and soil organic matter content. These technologies have been tested for over four years in local experimental field plots, and have provided results on the local effects upon individual environmental parameters. Despite the growing emphasis witnessed in literature upon the context-specificity which characterizes adaptation solutions, the frequent analysis at the field scale is limited in both scope and utility. There is a need to investigate the effects of adaptive SLM solutions at wider, regional scales. Thus, this study modeled the cumulative effect of each of the five selected SLM technologies with InVEST, a spatial analyst tool designed for ecosystem service quantification and

  18. Strategies for the disposition of high explosives resulting from dismantlement of nuclear weapons

    International Nuclear Information System (INIS)

    Many thousands of pounds of high quality main-charge explosives will result as surplus from the dismantlement of returns from the US nuclear weapons stockpile. The method most often employed for dealing with this surplus explosive is destruction by open burning. However, open burning as a means of treating excess explosives is losing favor because of environmental concerns associated with such an uncontrolled thermal destruction process. Thus, alternative processes for treatment of excess explosives from weapon dismantlement is discussed. These alternatives include: reformulation, crystalline component recovery, chemical conversion of the crystalline component to higher value products which may have civilian or military applications and, when necessary, treatment as waste in an environmentally benign fashion

  19. Bathymetry Determination via X-Band Radar Data: A New Strategy and Numerical Results

    Francesco Soldovieri

    2010-07-01

    Full Text Available This work deals with the question of sea state monitoring using marine X-band radar images and focuses its attention on the problem of sea depth estimation. We present and discuss a technique to estimate bathymetry by exploiting the dispersion relation for surface gravity waves. This estimation technique is based on the correlation between the measured and the theoretical sea wave spectra and a simple analysis of the approach is performed through test cases with synthetic data. More in detail, the reliability of the estimate technique is verified through simulated data sets that are concerned with different values of bathymetry and surface currents for two types of sea spectrum: JONSWAP and Pierson-Moskowitz. The results show how the estimated bathymetry is fairly accurate for low depth values, while the estimate is less accurate as the bathymetry increases, due to a less significant role of the bathymetry on the sea surface waves as the water depth increases.

  20. Changes in Ecosystem Services and related Livelihoods in the Mekong Delta: vulnerabilities and adaptation strategies

    Science.gov (United States)

    Sebesvari, Z.; Renaud, F. G.

    2014-12-01

    The Mekong Delta (Vietnam) is highly vulnerable to the many impacts of global environmental change as well as to the accelerating anthropogenic changes in the catchment and in the delta itself. Today the delta is an agricultural landscape controlled by engineering structures such as channels, dykes, embankments, and sluice gates. These structures have been constructed gradually over the last 200 years mainly for irrigation and flood control in the upper part of the delta and to control saline intrusion in the coastal areas. Recent changes in the hydrology mainly driven by upstream hydropower development on the mainstream and the tributaries of the Mekong will likely have far reaching impacts on the delta´s social-ecological systems through changes in e.g. sedimentation processes, nutrient transport as well as the health of aquatic ecosystems. Further threats to the delta include sea level rise and an increase in seasonal rainfall variability leading to an increase in flood variability. These changes affect the lives of millions of low-income inhabitants who depend on the ecosystem services provided by the Mekong for their livelihoods and sustenance. Since the changes in ecosystem service provision are occurring relatively fast while the resource dependency of the delta population is very high, adaptation becomes a challenge. An assessment of livelihood dependencies on ecosystem services requires an understanding of ecosystem services affected by different drivers of change, as well as of the types of livelihoods likely to be jeopardized as a result of these changes. We will present main ecosystem services supporting specific livelihoods, discuss how they are threatened, and analyse the merits of potential solutions. Options based solely on grey infrastructure might be problematic on the long term while an integration of ecosystem based solution such as a (re)adaptation of agricultural production systems to floods in the upper delta might be a more sustainable

  1. Transient tropospheric electric fields resulting from sudden changes in ionospheric conductivity

    1985-01-01

    Electric field mapping in the earth's atmosphere has been a research subject for more than 20 years. The present paper is concerned with the downward mapping of an ionospheric electric field into the troposphere following a 'sudden' - change in the atmospheric conductivity profile. The formulation is limited to the case of a static magnetic field which is vertical to the earth's surface. The obtained results are, therefore, most applicable at high latitudes. It is assumed that the 'sudden' change occurs within a fraction of a second and is sustained for a time of the order of at least several seconds. It is pointed out that such changes in ionospheric conductivity can occur as a result of sudden solar particle events (SPE) or particle precipitation into the lower ionosphere. Attention is given to theory, electric field calculations, and the obtained results.

  4. Index of film reject rates of mammographic service of Hospital Geral do Mexico. Strategies and results

    International Nuclear Information System (INIS)

    The reject of a radiographic film, not just means to do it again with the consequent increase in the dose to the patient, also means a failure in the service, as factors like fault in the equipment or by humans factors, like the selection of inadequate techniques or the bad positioning of the patient. In both cases, the analysis of the reject measures of radiographic studies, take special importance in the mammographic area, mainly if we consider the radiosensitivity of the tissues in study. This work, shows the methodology and the results of a study carried out in the Oncology Department of the General Hospital of Mexico, the biggest in the state, with the objective of knowing the principal causes of reject of films and establish through the respective analysis, the actions for correcting the detected failures, assuring so, low doses to patient, more precise diagnostic and the reduction of operating costs, that are the main objectives in a Program of Quality Assurance in Radiodiagnostic.

    2012-09-01

    Full Text Available Considering the fact that internationalization is a booming phenomenon, the paper aims to describe the process of internationalization of Brazilian companies in the heavy construction sector which have internationalized their activities through the execution of foreign direct investment (FDI. The focus is to understand the trajectories adopted in understanding the choices made, and the identification of the results obtained by these companies, experienced in international markets. Performing empirical research in business segment of heavy construction felt the need to broaden the scope of studies related to the internationalization of service firms. About the internationalization path adopted, the analysis of four cases showed similarities. To minimize the ignorance concerning market conditions, companies work normally with local partners. Concerning strategic choices and outcomes arising, the cases showed that the maintenance of external activity followed other criteria in addition to profitability. Maintaining external operations also been explained in terms of the need for constant updating. Different stages of internationalization were identified in the companies studied.

    The UA9 Collaboration, with support by EuCARD-AccNet, is investigating how bent crystals, used as primary collimators, could assist and improve the collimation process in modern hadron colliders like the LHC. From 2009 onwards the UA9 Collaboration has successfully tested silicon crystals at the SPS, performing measurements of the associated collimation efficiency by means of various methods and detectors. This report presents the main UA9 results, obtained with protons and Pb ions at 120 GeV/c and 270 GeV/c per charge from 2009 to 2012, which indicate that crystal assisted collimation is well mastered and understood. Specifically, reduced loss rates were demonstrated close to the crystal, as well as in a downstream off-momentum region, and, indeed, all around the ring. In addition, the importance of the crystal miscut angle was elucidated and a first industrial goniometer compliant with LHC specifications has become available. At the end of the report, the near-term plan for LHC crystal collimation is descri...

    Global climate change is known to affect the assembly of ecological communities by altering species' spatial distribution patterns, but little is known about how climate change may affect community assembly by changing species' temporal co-occurrence patterns, which is highly likely given the widely observed phenological shifts associated with climate change. Here, we analyzed a 29-year phenological data set comprising community-level information on the timing and span of temporal occurrence in 11 seasonally occurring animal taxon groups from 329 local meteorological observatories across China. We show that widespread shifts in phenology have resulted in community-wide changes in the temporal overlap between taxa that are dominated by extensions, and that these changes are largely due to taxa's altered span of temporal occurrence rather than the degree of synchrony in phenological shifts. Importantly, our findings also suggest that climate change may have led to less phenological mismatch than generally presumed, and that the context under which to discuss the ecological consequences of phenological shifts should be expanded beyond asynchronous shifts.

  8. The Northeastern United States Energy-Water Nexus: Climate Change Impacts and Alternative Water Management Strategies for the Power Sector

    Science.gov (United States)

    Miara, A.; Macknick, J.; Vorosmarty, C. J.; Cohen, S. M.; Rosenzweig, B.

    2014-12-01

    The Northeastern United States (NE) relies heavily on thermoelectric power plants (90% of total capacity) to provide electricity to more than 70 million people. This region's power plants require consistent, large volumes of water at sufficiently cold temperatures to generate electricity efficiently, and withdraw approximately 10.5 trillion gallons of water annually. Previous findings indicate that assessments of future electricity pathways must account for water availability, water temperature and the changing climate, as changes in these conditions may limit operational efficiency in the future. To account for such electric system vulnerabilities, we have created a link between an electricity system capacity expansion model (ReEDS) and a hydrologic model that is coupled to a power plant simulation model (FrAMES-TP2M) that allows for a new approach to analyze electricity system development, performance, and environmental impacts. Together, these coupled tools allow us to estimate electricity development and operations in the context of a changing climate and impacts on the seasonal spatial and temporal variability of water resources, downstream thermal effluents that cause plant-to-plant interferences and harm aquatic habitat, economic costs of water conservation methods and associated carbon emissions. In this study, we test and compare a business-as-usual strategy with three alternative water management scenarios that include changes in cooling technologies and water sources utilized for the years 2014-2050. Results of these experiments can provide useful insight into the feasibility of the electricity expansion scenarios in terms of associated water use and thermal impacts, carbon emissions, the cost of generating electricity, and also highlight the importance of accounting for water resources in future power sector planning and performance assessments.

    2014-01-01

    Full Text Available Background: Examining the pathologic progression of a pituitary adenoma from the point of a prepubescent child to an adult with gigantism affords us an opportunity to consider why patients may develop secretory or functioning tumors and raises questions about whether therapeutic interventions and surveillance strategies could be made to avoid irreversible phenotypic changes. Case Description: A patient underwent a sublabial transsphenoidal resection for a clinically non-functioning macroadenoma in 1999. He underwent radiation treatment and was transiently given growth hormone (GH supplementation as an adolescent. His growth rapidly traversed several percentiles and he was found to have elevated GH levels. The patient became symptomatic and was taken for a second neurosurgical procedure. Pathology and immunohistochemical staining demonstrated a significantly higher proportion of somatotroph cells and dense granularity; he was diagnosed with a functional somatotroph adenoma. Conclusions: While it is likely that the described observations reflect the manifestations of a functional somatotroph adenoma in development, it is possible that pubertal growth, GH supplementation, its removal, or radiation therapy contributed to the described endocrine and pathologic changes.

  10. A Lakatosian Conceptual Change Teaching Strategy Based on Student Ability to Build Models with Varying Degrees of Conceptual Understanding of Chemical Equilibrium

    Science.gov (United States)

    Niaz, M.

    The main objective of this study is to construct a Lakatosian teaching strategy that can facilitate conceptual change in students'' understanding of chemical equilibrium. The strategy is based on the premise that cognitive conflicts must have been engendered by the students themselves in trying to cope with different problem solving strategies. Results obtained (based on Venezuelan freshman students) show that the performance of the experimental group of students was generally better (especially on the immediate post tests) than that of the control group. It is concluded that a conceptual change teaching strategy must take into consideration the following aspects: a) core beliefs of the students in the topic (cf. ''hard core'', Lakatos 1970); b) exploration of the relationship between core beliefs and student alternative conceptions (misconceptions); c) cognitive complexity of the core belief can be broken down into a series of related and probing questions; d) students resist changes in their core beliefs by postulating ''auxiliary hypotheses'' in order to resolve their contradictions; e) students'' responses based on their alternative conceptions must be considered not as wrong, but rather as models, perhaps in the same sense as used by scientists to break the complexity of a problem; and f) students'' misconceptions be considered as alternative conceptions (theories) that compete with the present scientific theories and at times recapitulate theories scientists held in the past.

  11. Vulnerability of hydropower generation to climate change in China: Results based on Grey forecasting model

    International Nuclear Information System (INIS)

    This paper analyzes the long-term relationships between hydropower generation and climate factors (precipitation), hydropower generation capacity (installed capacity of hydropower station) to quantify the vulnerability of renewable energy production in China for the case of hydropower generation. Furthermore, this study applies Grey forecasting model to forecast precipitation in different provinces, and then sets up different scenarios for precipitation based on the IPCC Special Report on Emission Scenarios and results from PRECIS (Providing Regional Climate projections for Impacts Studies) model. The most important result found in this research is the increasing hydropower vulnerability of the poorest regions and the main hydropower generation provinces of China to climate change. Other main empirical results reveal that the impacts of climate change on the supply of hydropower generation in China will be noteworthy for the society. Different scenarios have different effects on hydropower generation, of which A2 scenario (pessimistic, high emission) has the largest. Meanwhile, the impacts of climate change on hydropower generation of every province are distinctly different, of which the Southwest part has the higher vulnerability than the average level while the central part lower. - Highlights: • The hydropower vulnerability will be enlarged with the rapid increase of hydropower capacity. • Modeling the vulnerability of hydropower in different scenarios and different provinces. • The increasing hydropower vulnerability of the poorest regions to climate change. • The increasing hydropower vulnerability of the main hydropower generation provinces. • Rainfall pattern caused by climate change would be the reason for the increasing vulnerability

  12. The effects of professional development on instructional strategies and the resulting influences on student learning for a physics curriculum

    Science.gov (United States)

    Cleavinger, Laurie

    In this study, the professional development for a physics program called Visual Quantum Mechanics (VQM) was observed and analyzed. Four of the participants in a summer institute as Kansas State University (KSU) volunteered to be observed by the researcher as they implemented the program into their classrooms during the next academic year. Observations were used to determine the effectiveness of the instructional strategies that they used. The students' perception of the laboratory sessions was evaluated and student understanding of the physics concepts also was determined. Qualitative and quantitative data analyses indicated that the professional development as presented and supported by the KSU team provided teachers with the information necessary to use the VQM program successfully with their students. However, only 30% of the teachers implemented the program during the following school year. Instructional strategies advocated by the VQM program included use of the hands-on equipment and computer simulations as well as discussion techniques. Observations revealed that students were more attentive during laboratory activities and less attentive during the discussions. Nevertheless, discussion proved to be a valuable component of this process. The researcher concluded that high quality professional development encouraged teaches to implement VQM in their classrooms. Although teachers did not always follow the instructional strategies advocated by the program, the inquiry-based hands-on activities and computer simulations kept students attentive. As a result, there was significant learning directly attributable to VQM for the students who participated in the study. Students who finished a complete learning cycle within the activities showed more significant learning than students who did not complete a learning cycle. Professional development can be designed to encourage teachers to implement new skills. For Visual Quantum Mechanics, emphasizing the importance of

    We present the first results from the Continuum Halos in Nearby Galaxies-an EVLA Survey (CHANG-ES), a new survey of 35 edge-on galaxies to search for both in-disk and extraplanar radio continuum emission. CHANG-ES is exploiting the new wide-band, multi-channel capabilities of the Karl G. Jansky Very Large Array (i.e., the Expanded Very Large Array or EVLA) with observations in two bands centered at 1.5 and 6 GHz in a variety of array configurations with full polarization. The motivation and science case for the survey are presented in a companion paper (Paper I). These first results are based on C-array test observations in both observing bands of the well-known radio halo galaxy, NGC 4631. In this paper, we outline the observations and the data reduction steps that are required for wide-band calibration and mapping of EVLA data, including polarization. With modest on-source observing times (30 minutes at 1.5 GHz and 75 minutes at 6 GHz for the test data), we have achieved best rms noise levels of 22 and 3.5 {mu}Jy beam{sup -1} at 1.5 GHz and 6 GHz, respectively. New disk-halo features have been detected, among them two at 1.5 GHz that appear as loops in projection. We present the first 1.5 GHz spectral index map of NGC 4631 to be formed from a single wide-band observation in a single array configuration. This map represents tangent slopes to the intensities within the band centered at 1.5 GHz, rather than fits across widely separated frequencies as has been done in the past and is also the highest spatial resolution spectral index map yet presented for this galaxy. The average spectral index in the disk is {alpha}-bar{sub 1.5GHz} = -0.84 {+-} 0.05 indicating that the emission is largely non-thermal, but a small global thermal contribution is sufficient to explain a positive curvature term in the spectral index over the band. Two specific star-forming regions have spectral indices that are consistent with thermal emission. Polarization results (uncorrected for

    Full Text Available Global climate change mitigation and CO2 emission reduction have promoted the revolutionary transformation in energy system. The core content of energy system revolutionary transformation is to replace the high-carbon energy system dominated by fossil energy with low-carbon energy system dominated by new and renewable energy and finally realize the near-zero emission of CO2. The new energy system transformation has also led to a reform in global economic and social development patterns. Developing low-carbon economy becomes the fundamental strategy of sustainable development under climate risk management and the only solution to getting on the road from industrial civilization to ecological civilization. China intends to achieve the peaking of CO2 emissions around 2030 and increase the share of non-fossil fuels in primary energy consumption to around 20% by 2030. Guided by the targets, China directs its economy development to a low-carbon pattern. Therefore, new and renewable power capacity need to reach 1300 GW, and the electricity generated should be 4 times of that in 2013 with a continuous increase rate of 6%–8% around 2030. The pace of energy substitution need to be accelerated and efficient, safe, clean, and low-carbon energy supply and consumption systems should be established besides strengthened energy conservation and improved energy efficient. Therefore, reform need be deepened, favorable policy system and market mechanism for energy revolution and low-carbon development need be established, energy pricing mechanism should be reformed, and national carbon market should be formed to provide a favorable policy and market environment for low-carbon technology innovation and industry development.

    2008-01-01

    This study examined unfamiliar and familiar listener attitudes towards the use of combined alphabet-topic cues and a control condition (habitual speech with no cues) associated with the speech of three individuals with severe mixed dysarthria. Two listener groups (N = 36) were shown experimentally imposed visual images of the combined alphabet-topic cue strategy in conjunction with recorded auditory presentations with the habitual speech of three individuals with mixed dysarthria. Using a 7-point Likert scale, listeners were asked to rate how effective they thought the speakers communicated; how comfortable they were communicating with the speakers; and how persistent they were in trying to understand the speakers. The results revealed that there were no significant differences in the attitude ratings of familiar listeners as compared to unfamiliar listeners. However, results revealed that rating of communicative effectiveness, comfort communicating with speakers and listener persistence were each more favourable when using the combined cue condition than purely habitual speech.The results suggest that augmentative and alternative communication strategies providing frequent and specific cues regarding the content and constituent words of a message may enhance the attitudes of listeners.

    Arid and semiarid ecosystems cover ~40% of Earth's terrestrial surface and make up ~35% of the U.S., yet we know surprisingly little about how climate change will affect these widespread landscapes. Like many dryland regions, the Colorado Plateau in the southwestern U.S. is predicted to experience climate change as elevated temperature and altered timing and amount of annual precipitation. We are using a long-term (>10 yr) factorial warming and supplemental rainfall experiment on the Colorado Plateau to explore how predicted changes in climate will affect vascular plant and biological soil crust community composition, biogeochemical cycling, and energy balance (biocrusts are a surface soil community of moss, lichen, and cyanobacteria that can make up as much as 70% of the living cover in drylands). While some of the responses we have observed were expected, many of the results are surprising. For example, we documented biocrust community composition shifts in response to altered climate that were significantly faster and more dramatic than considered likely for these soil communities that typically change over decadal and centennial timescales. Further, while we continue to observe important climate change effects on carbon cycling - including reduced net photosynthesis in vascular plants, increased CO2 losses from biocrust soils during some seasons, and changes to the interactions between water and carbon cycles - we have also found marked treatment effects on the albedo and spectral signatures of dryland soils. In addition to demonstrating the effects of these treatments, the strong relationships we observed in our experiments between biota and climate provide a quantitative framework for improving our representation of dryland responses to climate change. In this talk we will cover a range of datasets that, taken together, show: (1) large climate-driven changes to dryland biogeochemical cycling may be the result of both effects on existing communities, as well

    The techniques used in making reactivity change measurements on HECTOR are described and discussed. Pile period measurements were used in the majority of oases, though the pile oscillator technique was used occasionally. These two methods are compared. Flux determinations were made in the vicinity of the fuel element samples using manganese foils, and the techniques used are described and an error assessment made. Results of both reactivity change and flux measurements on 1.2 in. diameter uranium and plutonium-uranium alloy fuel elements are presented, these measurements being carried out in a variety of graphite moderated lattices at temperatures up to 450 deg.

  11. When we don't know the costs or the benefits: adaptive strategies for abating climate change

    International Nuclear Information System (INIS)

    Most quantitative studies of climate-change policy attempt to predict the greenhouse-gas reduction plan that will have the optimum balance of long-term costs and benefits. The authors find that the large uncertainties associated with the climate-change problem can make the policy prescriptions of this traditional approach unreliable. In this study the authors construct a large uncertainty space that includes the possibility of large and/or abrupt climate changes and/or of technology breakthroughs that radically reduce projected abatement costs. Computational experiments are used on a linked system of climate and economic models to compare the performance of a simple adaptive strategy - one that can make midcourse corrections based on observations of the climate and economic systems - and two commonly advocated 'best-estimate' policies based on different expectations about the long-term consequences of climate change. It was found that the 'Do-a-Little' and 'Emissions-Stabilization' best-estimate policies perform well in the respective regions of the uncertainty space where their estimates are valid, but can fail severely in those regions where their estimates are wrong. In contrast, the adaptive strategy can make midcourse corrections and avoid significant errors. While its success is no surprise, the adaptive-strategy approach provides an analytic framework to examine important policy and research issues that will likely arise as society adapts to climate change, which cannot be easily addressed in studies using best-estimate approaches. 44 refs., 15 figs., 3 tabs

  12. Strategies for addressing climate change: policy perspectives from around the world

    International Nuclear Information System (INIS)

    The greenhouse effect is intrinsically global. Accordingly, effective responses require global coordination. While limited policies have been adopted, notably for phasing out chlorofluorocarbons, there is no clear consensus as to what to do about other greenhouse gases. In this paper, we survey attitudes and policy responses among the nations of the world. Public opinion surveys are consistent in showing that considerable sensitivity to environmental issues exists virtually everywhere. On the other hand, there is acute awareness that other issues, especially economic development, can conflict with global climate-change mitigation goals. In such a state of uncertainty there is a strong argument to be made for implementing policies which are good ideas independent of greenhouse-gas considerations. There is also good reason to expand research. What is feasible depends strongly on present and changing attitudes of the citizens of the world, and of their governments. It is thus critical to follow closely the evolution of attitudes. The kind of work summarized in this paper needs to be updated on a continuing basis, and the results made available routinely to the global policy community. We conclude our review with several recommendations for research designed specifically to reduce uncertainty about costs and institutional issues relating to responses to global climate change.

  13. A quantitative strategy to detect changes in accessibility of protein regions to chemical modification on heterodimerization

    2009-01-01

    We describe a method for studying quantitative changes in accessibility of surface lysine residues of the PB1 subunit of the influenza RNA polymerase as a result of association with the PA subunit to form a PB1-PA heterodimer. Our method combines two established methods: (i) the chemical modification of surface lysine residues of native proteins by N-hydroxysuccinimidobiotin (NHS-biotin) and (ii) the stable isotope labeling of amino acids in cell culture (SILAC) followed by tryptic digestion and mass spectrometry. By linking the chemical modification with the SILAC methodology for the first time, we obtain quantitative data on chemical modification allowing subtle changes in accessibility to be described. Five regions in the PB1 monomer showed altered reactivity to NHS-biotin when compared with the [PB1-PA] heterodimer. Mutational analysis of residues in two such regions—at K265 and K481 of PB1, which were about three- and twofold, respectively, less accessible to biotinylation in the PB1-PA heterodimer compared with the PB1 monomer, demonstrated that both K265 and K481 were crucial for polymerase function. This novel assay of quantitative profiling of biotinylation patterns (Q-POP assay) highlights likely conformational changes at important functional sites, as observed here for PB1, and may provide information on protein–protein interaction interfaces. The Q-POP assay should be a generally applicable approach and may detect novel functional sites suitable for targeting by drugs. PMID:19517532

  14. Climate Change Potential Impacts on the Built Environment and Possible Adaptation Strategies

    Science.gov (United States)

    2014-01-01

    The built environment consists of components that exist at a range of scales from small (e.g., houses, shopping malls) to large (e.g., transportation networks) to highly modified landscapes such as cities. Thus, the impacts of climate change on the built environment may have a multitude of effects on humans and the land. The impact of climate change may be exacerbated by the interaction of different events that singly may be minor, but together may have a synergistic set of impacts that are significant. Also, mechanisms may exist wherein the built environment, particularly in the form of cities, may affect weather and the climate on local and regional scales. Hence, a city may be able to cope with prolonged heat waves, but if this is combined with severe drought, the overall result could be significant or even catastrophic, as accelerating demand for energy to cooling taxes water supplies needed both for energy supply and municipal water needs. This presentation surveys potential climate change impacts on the built environment from the perspective of the National Climate Assessment, and explores adaptation measures that can be employed to mitigate these impacts.

    Full Text Available The Bølling-Allerød (BA, starting ~ 14.5 ka BP is one of the most pronounced abrupt warming periods recorded in ice and pollen proxies. The leading explanation of the cause of this warming is a sudden increase in the rate of deepwater formation in the North Atlantic Ocean and the resulting effect on the heat transport by the Atlantic Meridional Overturning Circulation (AMOC. In this study, we used the University of Victoria (UVic Earth System-Climate Model (ESCM to run simulations, in which a freshwater perturbation initiated a BA-like warming period. We found that under present climate conditions, the AMOC intensified when freshwater was added to the Southern Ocean. However, under Heinrich event 1 (HE1, ~ 16 ka BP climate conditions, the AMOC only intensified when freshwater was extracted from the North Atlantic Ocean, possibly corresponding to an increase in evaporation or a decrease in precipitation in this region. The intensified AMOC led to a warming in the North Atlantic Ocean and a cooling in the South Atlantic Ocean, resembling the bipolar seesaw pattern typical of the last glacial period.

    In addition to the physical response, we also studied the simulated vegetation response around the Atlantic Ocean region. Corresponding with the bipolar seesaw hypothesis, the rainbelt associated with the Intertropical Convergence Zone (ITCZ shifted northward and affected the vegetation pattern in the tropics. The most sensitive vegetation area was found in tropical Africa, where grass cover increased and tree cover decreased under dry climate conditions. An equal but opposite response to the collapse and recovery of the AMOC implied that the change in vegetation cover was transient and robust to an abrupt climate change such as during the BA period, which is also supported by paleovegetation data. The results are in agreement with paleovegetation records from Western tropical Africa, which also show a reduction in forest cover during this

    Full Text Available Agricultural biodiversity and related agro-ecological measures could play a crucial role in the agro-ecosystems adaptation to climate changes, thus sustaining crop production. The objective of this study was to assess the suitability (and the best combination of agro-ecological techniques as potential resilience strategies in organic horticultural systems in a Mediterranean environment. A long-term experimental device called MITIORG (Long-term climatic change adaptation in organic farming: synergistic combination of hydraulic arrangement, crop rotations, agro-ecological service crops and agronomic techniques is set-up at Metaponto (MT, testing the following agro-ecological measures as well as organic and conservation farming best practices: i hydraulic arrangement by a kind of ridge-furrow system; ii cash crop rotations; iii agro-ecological service crops (ASC introduction; iv ASC termination techniques (green manure vs roller crimper; and v organic fertilisation. The research here reported was carried out during the 2014-2015 season in the MITIORG device, on a rotation of cauliflower (Brassica oleracea L. and tomato (Solanum lycopersicum L. crops. A detailed description of the scientific cognitive process that led to setup of the device, its components explanation, as well as preliminary yield results are reported. The outcomes suggest that organic vegetable cropping systems, designed following agro-ecological principles, are able to sustain yield of cash crops in rotation, in spite of changes in temperature and rainfall of the study site. Experimental data available in the next years will allow a deeper integrated analysis of the manifold effects of agro-ecological measures on horticultural systems.

    BACKGROUND Retinoblastoma (RB) is the most common malignant tumor of the eye in childhood. The objective of this paper was to investigate carboplatin (CAR)- and melphalan (MEL)-induced dynamic module changes in RB based on multiple (M) differential networks, and to generate systems-level insights into RB progression. MATERIAL AND METHODS To achieve this goal, we constructed M-differential co-expression networks (DCNs), assigned a weight to each edge, and identified seed genes in M DCNs by ranking genes based on their topological features. Starting with seed genes, a module search was performed to explore candidate modules in CAR and MEL condition. M-DMs were detected according to significance evaluations of M-modules, which originated from refinement of candidate modules. Further, we revealed dynamic changes in M-DM activity and connectivity on the basis of significance of Module Connectivity Dynamic Score (MCDS). RESULTS In the present study, M=2, a total of 21 seed genes were obtained. By assessing module search, refinement, and evaluation, we gained 18 2-DMs. Moreover, 3 significant 2-DMs (Module 1, Module 2, and Module 3) with dynamic changes across CAR and MEL condition were determined, and we denoted them as dynamic modules. Module 1 had 27 nodes of which 6 were seed genes and 56 edges. Module 2 was composed of 28 nodes and 54 edges. A total of 28 nodes interacted with 45 edges presented in Module 3. CONCLUSIONS We have identified 3 dynamic modules with changes induced by CAR and MEL in RB, which might give insights in revealing molecular mechanism for RB therapy. PMID:27144687

    In Senegal, due to the young age of the population (60%) the concerns of the old tend to be put in the background. And yet, problems related to old age are a reality. These problems come up not in terms of demography (the old represent only 4.7% of the population), but in terms of the breaking-up of the social fabric, urbanization and the dismantling of the solidarity and poverty networks. This work is based on a collection of qualitative data from three studies conducted between 2008 and 2011 with the elderly to assess their real- life experiences, their perception of aging, their challenges and coping strategies. The results showed a transformation in the role and status of the old; this transformation being caused by social and society-related mutations. As a result, the inter-generation solidarity links have much loosened in the urban areas making the old people more vulnerable (in economic, social, health terms), especially those in charge of a family. The situation has been made worse by the unemployment affecting their offspring. In addition, the old people, who are often suffering from chronic diseases, find it hard to take charge of their medical expenses, despite the institution of the National Sesame Health Plan for the old or free health care policy. This has made them even more vulnerable. Yet before this precarious situation, the elderly develop strategies to cope with difficulties. Some recommendations have been made with a view to improving their lives and socioeconomic condition. PMID:26852947

  20. Model results for the ionospheric E region: solar and seasonal changes

    Directory of Open Access Journals (Sweden)

    J. E. Titheridge

    Full Text Available A new, empirical model for NO densities is developed, to include physically reasonable variations with local time, season, latitude and solar cycle. Model calculations making full allowance for secondary production, and ionising radiations at wavelengths down to 25 Å, then give values for the peak density NmE that are only 6% below the empirical IRI values for summer conditions at solar minimum. At solar maximum the difference increases to 16%. Solar-cycle changes in the EUVAC radiation model seem insufficient to explain the observed changes in NmE, with any reasonable modifications to current atmospheric constants. Hinteregger radiations give the correct change, with results that are just 2% below the IRI values throughout the solar cycle, but give too little ionisation in the E-F valley region. To match the observed solar increase in NmE, the high-flux reference spectrum in the EUVAC model needs an overall increase of about 20% (or 33% if the change is confined to the less well defined radiations at λ < 150 Å. Observed values of NmE show a seasonal anomaly, at mid-latitudes, with densities about 10% higher in winter than in summer (for a constant solar zenith angle. Composition changes in the MSIS86 atmospheric model produce a summer-to-winter change in NmE of about –2% in the northern hemisphere, and +3% in the southern hemisphere. Seasonal changes in NO produce an additional increase of about 5% in winter, near solar minimum, to give an overall seasonal anomaly of 8% in the southern hemisphere. Near solar maximum, reported NO densities suggest a much smaller seasonal change that is insufficient to produce any winter increase in NmE. Other mechanisms, such as the effects of winds or electric fields, seem inadequate to explain the observed change in NmE. It therefore seems possible that current satellite

    Nitrogen (N) or phosphorus (P) limits primary productivity in nearly every ecosystem worldwide, yet how limitation changes over time, particularly in connection to variation in environmental drivers, remains understudied. We evaluated temporal and species-specific variability in the relative importance of N and P limitation among tropical macroalgae in two-factor experiments conducted twice after rains and twice after dry conditions to explore potential linkages to environmental drivers. We studied three common macroalgal species with varying ecological strategies: a fast-growing opportunist, Dictyota bartayresiana; and two calcifying species likely to be slower growing, Galaxaura fasciculata and Padina boryana. On the scale of days to weeks, nutrient responses ranged among and within species from no limitation to increases in growth by 20 and 40 % over controls in 3 d with N and P addition, respectively. After light rain or dry conditions, Dictyota grew rapidly (up to ~60 % in 3 d) with little indication of nutrient limitation, while Padina and Galaxaura shifted between N, P, or no limitation. All species grew slowly or lost mass after a large storm, presumably due to unfavorable conditions on the reef prior to the experiment that limited nutrient uptake. Padina and Galaxaura both became nutrient limited 3 d post-storm, while Dictyota did not. These results suggest that differing capabilities for nutrient uptake and storage dictate the influence of nutrient history and thus drive nutrient responses and, in doing so, may allow species with differing ecological strategies to coexist in a fluctuating environment. Moreover, the great variability in species' responses indicates that patterns of nutrient limitation are more complex than previously recognized, and generalizations about N versus P limitation of a given system may not convey the inherent complexity in governing conditions and processes.

    PURPOSE The Using Learning Teams for Reflective Adaptation (ULTRA) study used facilitated reflective adaptive process (RAP) teams to enhance communication and decision making in hopes of improving adherence to multiple clinical guidelines; however, the study failed to show significant clinical improvements. The purpose of this study was to examine qualitative data from 25 intervention practices to understand how they engaged in a team-based collaborative change management strategy and the types of issues they addressed. METHODS We analyzed field notes and interviews from a multimethod practice assessment, as well as field notes and audio-taped recordings from RAP meetings, using an iterative group process and an immersion-crystallization approach. RESULTS Despite a history of not meeting regularly, 18 of 25 practices successfully convened improvement teams. There was evidence of improved practice-wide communication in 12 of these practices. At follow-up, 8 practices continued RAP meetings and found the process valuable in problem solving and decision making. Seven practices failed to engage in RAP primarily because of key leaders dominating the meeting agenda or staff members hesitating to speak up in meetings. Although the number of improvement targets varied considerably, most RAP teams targeted patient care-related issues or practice-level organizational improvement issues. Not a single practice focused on adherence to clinical care guidelines. CONCLUSION Primary care practices can successfully engage in facilitated team meetings; however, leaders must be engaged in the process. Additional strategies are needed to engage practice leaders, particularly physicians, and to target issues related to guideline adherence. PMID:20843884

    Recent research suggests that motivation improves cognitive functions but the particular mechanisms and precise behavioural conditions involved in such improvement still remain unknown. Particularly, it is unclear when in time and in which conditions these mechanisms are engaged. In the present study, we aimed to look at the neural markers of cognitive control strategies in different motivational conditions (motivation vs neutral) with different levels of difficulty (high vs low). Twenty-five adults completed a newly designed task in the four conditions above. Three ERP components were analysed: the CNV, LRP and P3b. We found that a motivational situation triggers the use of a proactive strategy when low cognitive control is required. A reactive strategy was used in a non-motivational situation and for difficult trials. Our study is also the first to provide evidence that the difference between proactive and reactive strategies occurs after the first stimulus (cue) is processed. PMID:25708173

    The Department of Interior Northeast Climate Science Center (NE CSC) is part of a federal network of eight Climate Science Centers created to provide scientific information, tools, and techniques that managers and other parties interested in land, water, wildlife and cultural resources can use to anticipate, monitor, and adapt to climate change. The consortium approach taken by the CSCs allows the academic side of the Centers to gather expertise across departments, disciplines, and even institutions. This interdisciplinary approach is needed for successfully meeting regional needs for climate impact assessment, adaptive management, education, and stakeholder outreach. Partnership with the federal government facilitates interactions with the key on-the-ground stakeholders who are able to operationalize the results and conclusions of that research, monitor the progress of management actions, and provide feedback to refine future methodology and decisions as new information on climate impacts is discovered. For example, NE CSC researchers are analyzing the effect of climate change on the timing and volume of seasonal and annual streamflows and the concomitant effects on ecological and cultural resources; developing techniques to monitor tree range dynamics as affected by natural disturbances which can enable adaptation of projected climate impacts; studying the effects of changes in the frequency and magnitude of drought and stream temperature on brook trout habitats, spatial distribution and population persistence; and conducting assessments of northeastern regional climate projections and high-resolution downscaling. Project methods are being developed in collaboration with stakeholders and results are being shared broadly with federal, state, and other partners to implement and refine effective and adaptive management actions.

    Heterothermic insects like honeybees, foraging in a variable environment, face the challenge of keeping their body temperature high to enable immediate flight and to promote fast exploitation of resources. Because of their small size they have to cope with an enormous heat loss and, therefore, high costs of thermoregulation. This calls for energetic optimisation which may be achieved by different strategies. An 'economizing' strategy would be to reduce energetic investment whenever possible, ...

    Development of sustainable water management strategies involves analysing current and future vulnerability, identification of adaptation possibilities, effect analysis and evaluation of the strategies under different possible futures. Recent studies on water management often followed the pressure-effect chain and compared the state of social, economic and ecological functions of water systems in one or two future situations. The future is, however, more complex and dynamic. Our approach starts at the end of the cause-effect chain by describing optimal conditions and critical thresholds for each water-related function in terms of their physical boundary conditions. This gives an indication of the current and future vulnerability. By comparing the optimal conditions with the physical conditions under the current and future climate and sea level we can identify mismatches. Where these occur are the vulnerable ‘hotspots' for which adaptation strategies should be defined. We developed a rapid assessment model to analyse the effectiveness of strategies for a large set of transient scenarios, in order to evaluate the strategies on robustness. This model describes the Pressure-State-Impact-Response chain of a delta system and exists of simple cause-effect relations based on outcomes of vulnerability analyses, complex hydrological models and studies on social responses. With the model transient scenarios are considered. These scenarios comprise time series that include trends, unexpected events, floods and droughts and the interaction between water system and society. We present the concept methodology for sustainable water management strategies by means of an imaginary case.

    In order to ensure long-term climate data records for the Greenland Ice Sheet (GIS), ESA have launched the Climate Change Initiative (CCI). This work presents the preliminary steps towards the Ice Sheet CCI's surface elevation change (SEC) derivation using radar altimeter data. In order to find the...... most optimal method, a Round Robin exercise was conducted in which the scientific community was asked to provide their best SEC estimate over the Jakobshavn Isbr drainage basin. The participants used both repeat-track (RT), overlapping footprints, and the cross-over (XO) methods, and both ICESat laser...... and Envisat radar altimeter data were used. Based on this and feedback sheets describing their methods we found that a combination of the RT and XO techniques yielded the best results. In the following, the obtained results will be presented and discussed....

    The structure of forests stands changes continuously as a result of forest growth and both natural and anthropogenic disturbances like windthrow or management activities – planting/cutting of trees. These structure changes can stabilize or destabilize forest stands in terms of their resistance...... to wind damage. The driving force behind the damage is the climate, but the magnitude and sign of resulting effect depend on tree species, management method and soil conditions. The projected increasing frequency of weather extremes in the whole and severe storms in particular might produce wide area...... damage in European forest ecosystems during the 21st century. To assess the possible wind damage and stabilization/destabilization effects of forest management a number of numeric experiments are carried out for the region of Solling, Germany.

    Climate change (CC) scenarios for the Mediterranean region include an increase in the frequency and intensity of extreme weather events such as drought periods. higher average temperatures and evapotranspiration, combined with the decrease of annual precipitation may strongly affect the sustainability of water resources. In face of these risks, improving water management actions? by anticipating necessary operational measures is required to insure water quantity and quality according to the needs of the populations and irrigation in agriculture. This is clearly the case of the Alentejo region, southern Portugal, where present climatic conditions already pose significant challenges to water resources stakeholders, mainly from the agricultural and the urban supply sectors. With this in mind, the GestAqua.AdaPT project is underway during 2015 and 2016, aiming at analyzing CC impacts until 2100 and develop operational procedures to ensure water needs are adequately satisfied in the Monte Novo and Vigia reservoirs, which supply water for the city of Évora and nearby irrigation systems. Specific project objectives include: a) defining management and operational adaptation strategies aiming to ensure resource sustainability, both quantitatively and qualitatively; b) evaluate future potential costs and available alternatives to the regional water transfer infrastructure linked with the large Alqueva reservoir implemented in 2011; c) defining CC adaptation strategies to reduce irrigation water needs and d) identification of CC adaptation strategies which can be suitable also to other similar water supply systems. The methodology is centered on the implementation of a cascade of modeling tools, allowing the integrated simulation of the multiple variables under analysis. The project is based on CC scenarios resulting from the CORDEX project for 10 combinations of Global and regional climate models (GCMs and RCMs). The study follows by using two of these combinations

    Many countries are interested in reducing electricity consumption in connection with that the electricity demand has been increasing in recent years. Price control is often used as a method of controlling electricity demand in the short-term. However, even if price control causes to decrease in electricity use, the decrease in electricity demand results in a decrease in economic activity as electricity use plays a role in one of input factors. In this respect, this research analyze how change...

    The impacts of climate change on nitrogen (N) in a lowland chalk stream are investigated using a dynamic modelling approach. The INCA-N model is used to simulate transient daily hydrology and water quality in the River Kennet using temperature and precipitation scenarios downscaled from the General Circulation Model (GCM) output for the period 1961-2100. The three GCMs (CGCM2, CSIRO and HadCM3) yield very different river flow regimes with the latter projecting significant periods of drought in the second half of the 21st century. Stream-water N concentrations increase over time as higher temperatures enhance N release from the soil, and lower river flows reduce the dilution capacity of the river. Particular problems are shown to occur following severe droughts when N mineralization is high and the subsequent breaking of the drought releases high nitrate loads into the river system. Possible strategies for reducing climate-driven N loads are explored using INCA-N. The measures include land use change or fertiliser reduction, reduction in atmospheric nitrate and ammonium deposition, and the introduction of water meadows or connected wetlands adjacent to the river. The most effective strategy is to change land use or reduce fertiliser use, followed by water meadow creation, and atmospheric pollution controls. Finally, a combined approach involving all three strategies is investigated and shown to reduce in-stream nitrate concentrations to those pre-1950s even under climate change. (author)

    Many bioelectric signals have a complex internal structure that can be a rich source of information on the tissue or cell processes. The structure of such signals can be analysed in detail by applying digital methods of signal processing. Therefore, of substantial use in diagnosis of the coronary arterial disease is the method of digital enhancement of increasing signal resolution ECG (NURSE-ECG), permitting detection of temporary changes in the electric potentials in the cardiac muscle in the process of depolarisation. Thanks to the application of NURSE-ECG it has become possible to detect relatively small changes in the electric activity of particular fragments of the cardiac muscle undetectable by the standard ECG method, caused by ischemia, the effect of a drug or infarct. The aim of this study was to identify and analyse changes in the electric activity of the cardiac muscle as a result of the Coronary Artery Bypass Graft (CABG) operation. In this study the method of NURSE-ECG has been applied in order to identify and analyse changes in the electric activity of the cardiac muscle as a result of the CABG operation. In the study performed in cooperation of the Institute of Physics Adam Mickiewicz University and the Strus Hospital, Cardiac Surgery Ward, 37 patients with advanced coronary arterial disease were asked to participate. The patients were examined prior to the operation, on the day after the operation and two months after the operation and a year after the operation. The ECG recordings were subjected to a numerical procedure of resolution enhancement by a NURSE-ECG program to reveal the tentative changes in the electric potential of the cardiac muscle on its depolarisation. Results of the study have shown that the NURSE ECG method can be applied to monitor changes in the electric activity of the cardiac muscle occurring as a result of CABG operation. One the second day after the operation in the majority of patients (70%) a rapid decrease of the total

    From the combined use of different observations/parameters, from the refinement of data analysis methods and the development of suitable physical models, we are expecting major progresses in the research on earthquake's preparatory phases. More than from the use of a single parameter approach, reduced false alarm rates and improved reliability and precision (in the space-time domain) of predictions, are expected from a multi-parameter observational, multi-disciplinary, research, strategy. Less than one year after its start, PRE-EARTHQUAKES FP7 Project already demonstrated its capability to commit together independent expertise and different observation capabilities in order: a) to substantially improve our knowledge of preparatory phases of earthquakes and their possible precursors; b) to promote a worldwide Earthquake Observation System (EQuOS) as a dedicated component of GEOSS (Global Earth Observation System of Systems); c) to develop and offer to the international scientific community an integration platform where independent observations and new data analysis methodologies devoted to the research on/of earthquake precursors can be collected and cross-validated. In this paper results achieved so far, in particular on the earthquakes selected as test cases occurred in recent years in Italy (M6.3 Abruzzo April 2009), Sakhalin (M6,2, Nevelsk, August 2007) and Turkey (M6,1, Elazig March 2010) will be presented emphasizing the significant added values guaranteed by a multi-parameter, multi-disciplinary strategy.

    The conventional algorithm for HIV testing based on the confirmation of all positive anti-HIV screening reactions by Western blot (WB) is too expensive for developing countries. We investigated the validity of confirming positive screening assay reactions by a second screening test, limiting the use of the supplemental assay to the discrepant test results (algorithm 3), or screening all sera with 2 different assays and retesting all discrepant results by a supplemental assay (algorithm 4) on a panel of 519 sera in a regional reference laboratory in Lubumbashi, Zaire. Combining the Vironostika anti-HTLV-III ELISA with HIV Chek 1 + 2 or Clonatec Rapid HIV 1/2 Ab on all samples and retesting the discrepant results in WB or a line immunoassay (INNO-LIA) (algorithm 4), yielded a sensitivity of 100% and specificities of 98.4% and 99.0% respectively, at costs of 7.3 US $ and 9.3 US $ per test, respectively, for a 40% prevalence of HIV antibody positive samples. The conventional algorithm scored a sensitivity of 97.1% and a specificity of 100% for 11.3 US $ per test. The testing strategy of combining HIV Chek 1 + 2 and Clonatec Rapid HIV 1/2 Ab, an interesting option for small isolated centra, had a 96.6% sensitivity, but yielded only a slightly better specificity of 99.0%, as compared to 97.8% for HIV Chek alone. The price of combining the two simple assays using algorithm 3 was 6.8 US $ per test, using algorithm 4 was 10.6 US $. HIV testing strategies based on ELISA and a simple HIV test are a valuable alternative for reference laboratories faced with a high prevalence of HIV positive samples. PMID:1789703

  18. The future of spaceborne altimetry. Oceans and climate change: A long-term strategy

    International Nuclear Information System (INIS)

    The ocean circulation and polar ice sheet volumes provide important memory and control functions in the global climate. Their long term variations are unknown and need to be understood before meaningful appraisals of climate change can be made. Satellite altimetry is the only method for providing global information on the ocean circulation and ice sheet volume. A robust altimeter measurement program is planned which will initiate global observations of the ocean circulation and polar ice sheets. In order to provide useful data about the climate, these measurements must be continued with unbroken coverage into the next century. Herein, past results of the role of the ocean in the climate system is summarized, near term goals are outlined, and requirements and options are presented for future altimeter missions. There are three basic scientific objectives for the program: ocean circulation; polar ice sheets; and mean sea level change. The greatest scientific benefit will be achieved with a series of dedicated high precision altimeter spacecraft, for which the choice of orbit parameters and system accuracy are unencumbered by requirements of companion instruments

    Biological soil crusts (biocrusts) colonize plant interspaces in many drylands and are critical to soil nutrient cycling. Multiple climate change and land use factors have been shown to detrimentally impact biocrusts on a macroscopic (i.e., visual) scale. However, the impact of these perturbations on the bacterial components of the biocrusts remains poorly understood. We employed multiple long-term field experiments to assess the impacts of chronic physical (foot trampling) and climatic changes (2°C soil warming, altered summer precipitation [wetting], and combined warming and wetting) on biocrust bacterial biomass, composition, and metabolic profile. The biocrust bacterial communities adopted distinct states based on the mechanism of disturbance. Chronic trampling decreased biomass and caused small community compositional changes. Soil warming had little effect on biocrust biomass or composition, while wetting resulted in an increase in the cyanobacterial biomass and altered bacterial composition. Warming combined with wetting dramatically altered bacterial composition and decreased Cyanobacteria abundance. Shotgun metagenomic sequencing identified four functional gene categories that differed in relative abundance among the manipulations, suggesting that climate and land use changes affected soil bacterial functional potential. This study illustrates that different types of biocrust disturbance damage biocrusts in macroscopically similar ways, but they differentially impact the resident soil bacterial communities, and the communities' functional profiles can differ depending on the disturbance type. Therefore, the nature of the perturbation and the microbial response are important considerations for management and restoration of drylands. PMID:26276111

    disturbance methodology. Of the four factors, oxygen availability had the least influence on respiration and showed no change in baseline after the initial degassing event, however substrate transport, physical abrasion, and wetting yielded more complex patterns. Isolated wetting events did not consistently show a change in respiration after the initial pulse, but yet when wetting occurred directly after physical abrasion the rate of respiration was altered. Substrate transport did not appear to stimulate any SOM response, suggesting that the island hypothesis does not apply in these soils, and that any impact of moisture additions must be a result of moisture-microbe or moisture-SOM interactions, and not redistribution. Physical abrasion also contributed to the response of wetting events and by blending factors surprising results surfaced. The influence of soil physical environment on SOM stability is new and potentially important work, but further experimentation is essential to better understand these complex results.
