  1. The Future of Nonproliferation in a Changed and Changing Environment: A Workshop Summary

    SciTech Connect

    Dreicer, M.

    2016-08-30

    The Center for Global Security Research and Global Security Principal Directorate at Lawrence Livermore National Laboratory convened a workshop in July 2016 to consider “The Future of Nonproliferation in a Changed and Changing Security Environment.” We took a broad view of nonproliferation, encompassing not just the treaty regime but also arms control, threat reduction, counter-­proliferation, and countering nuclear terrorism. We gathered a group of approximately 60 experts from the technical, academic, political, defense and think tank communities and asked them what—and how much—can reasonably be accomplished in each of these areas in the 5 to 10 years ahead. Discussion was on a not-­for-­attribution basis. This document provides a summary of key insights and lessons-­learned and is provided to help stimulate broader public discussion of these issues. It is a collection of ideas as informally discussed and debated among a group of experts. The ideas reported here are the personal views of individual experts and should not be attributed to Lawrence Livermore National Laboratory.

  2. Ecotones in a changing environment: Workshop on ecotones and global change

    Risser, P.G.

    1990-02-01

    The Scientific Committee on Problems of the Environment (SCOPE) has organized an international project to synthesize and advance current theory on the influence of ecotones, or transition zones between ecosystems, on biodiversity and flows of energy, nutrients, water, and project is other materials between ecosystems. In particular, the entire project is designed to evaluate the influence of global climate change and land-use practices on biodiversity and ecological flows associated with ecotones, and will assess the feasibility of monitoring ecotones as early indicators of global change. The later stages of the project will recommend landscape management strategies for ecotones that produce desirable patterns of biodiversity and ecological flows. The result of the project--a comprehensive body of information on the theory and management of biodiversity and ecological flows associated with ecotones--will be part of the planning for research to be carried out under the International Geosphere-Biosphere Program.

  7. Visual Computing Environment Workshop

    Lawrence, Charles (Compiler)

    1998-01-01

    The Visual Computing Environment (VCE) is a framework for intercomponent and multidisciplinary computational simulations. Many current engineering analysis codes simulate various aspects of aircraft engine operation. For example, existing computational fluid dynamics (CFD) codes can model the airflow through individual engine components such as the inlet, compressor, combustor, turbine, or nozzle. Currently, these codes are run in isolation, making intercomponent and complete system simulations very difficult to perform. In addition, management and utilization of these engineering codes for coupled component simulations is a complex, laborious task, requiring substantial experience and effort. To facilitate multicomponent aircraft engine analysis, the CFD Research Corporation (CFDRC) is developing the VCE system. This system, which is part of NASA's Numerical Propulsion Simulation System (NPSS) program, can couple various engineering disciplines, such as CFD, structural analysis, and thermal analysis.

    One of the main experimental monitors used to determine the environment in the payload bay was the Induced Environment Contamination Monitor. This package of instruments has made environmental measurements during STS flights with a high degree of success. This has shown that the shuttle environment is relatively free of contaminants, except for special instances of increased abundance of methane, water vapor and particulates. Results of these measurements are rapidly becoming more available. In establishing the Shuttle Environment Workshop, the findings were shared with scientific experimenters, users and other individuals who need to know what the Shuttle is like and what experimenters may expect in the payload bay. The Workshop was centered around results obtained from the environmental measurements made on the Shuttle. The program agenda for the workshop is given. The procedures and flow of communications for the workshop are indicated.

    Mars Recent Climate Change Workshop NASA/Ames Research Center May 15-17, 2012 Climate change on Mars has been a subject of great interest to planetary scientists since the 1970's when orbiting spacecraft first discovered fluvial landforms on its ancient surfaces and layered terrains in its polar regions. By far most of the attention has been directed toward understanding how "Early Mars" (i.e., Mars >~3.5 Gya) could have produced environmental conditions favorable for the flow of liquid water on its surface. Unfortunately, in spite of the considerable body of work performed on this subject, no clear consensus has emerged on the nature of the early Martian climate system because of the difficulty in distinguishing between competing ideas given the ambiguities in the available geological, mineralogical, and isotopic records. For several reasons, however, the situation is more tractable for "Recent Mars" (i.e., Mars during past 20 My or so). First, the geologic record is better preserved and evidence for climate change on this time scale has been building since the rejuvenation of the Mars Exploration Program in the late 1990's. The increasing coverage of the planet from orbit and the surface, coupled with accurate measurements of surface topography, increasing spatial resolution of imaging cameras, improved spectral resolution of infrared sensors, and the ability to probe the subsurface with radar, gamma rays, and neutron spectroscopy, has not only improved the characterization of previously known climate features such as polar layered terrains and glacier-related landforms, but has also revealed the existence of many new features related to recent climate change such as polygons, gullies, concentric crater fill, and a latitude dependent mantle. Second, the likely cause of climate change - spin axis/orbital variations - is more pronounced on Mars compared to Earth. Spin axis/orbital variations alter the seasonal and latitudinal distribution of sunlight, which can

    Lighting is a central and critical aspect of control in environmental research for plant research and is gaining recognition as a significant factor to control carefully for animal and human research. Thus this workshop was convened to reevaluate the technology that is available today and to work toward developing guidelines for the most effective use of lighting in controlled environments with emphasis on lighting for plants but also to initiate interest in the development of improved guidelines for human and animal research. There are a number of established guidelines for lighting in human and animal environments. Development of new lighting guidelines is necessary for three reasons: (1) recent scientific discoveries show that in addition to supporting the sensation of vision, light has profound nonvisual biological and behavioral effects in both animals and humans; (2) federal regulations (EPACT 1992) are requiring all indoor environments to become more energy efficient with a specific emphasis on energy conservation in lighting; (3) lighting engineers and manufacturers have developed a wealth of new light sources and lighting products that can be applied in animal and human environments. The workshop was aimed at bringing together plant scientists and physical scientists to interact in the discussions. It involved participation of biological scientists involved in studying mechanisms of light reactions and those involved in utilizing lighting for production of plants and maintenance of animals in controlled environments. It included participation of physical scientists from universities and government involved in research as well as those from industry involved in producing lamps and in construction of controlled growth facilities. Selected papers are indexed separately for inclusion in the Energy Science and Technology Database.

  18. Light in Thermal Environments (LITE) Workshop

    NASA Technical Reports Server (NTRS)

    1993-01-01

    Light emitted from high temperature black smokers (350 C) at mid-ocean ridge spreading centers has been documented, but the source of this light and its photochemical and biological consequences have yet to be investigated. Preliminary studies indicate that thermal radiation alone might account for the 'glow' and that a novel photoreceptor in shrimp colonizing black smoker chimneys may detect this 'glow.' A more controversial question is whether there may be sufficient photon flux of appropriate wavelengths to support geothermally-driven photosynthesis (GDP) by microorganisms. Although only a very low level of visible and near infrared light may be emitted from any single hydrothermal vent, several aspects of the light make it of more than enigmatic interest. First, the light is clearly linked to geophysical (and perhaps geochemical) processes; its attributes may serve as powerful index parameters for monitoring change in these processes. Second, while the glow at a vent orifice is a very local phenomenon, more expansive subsurface environments may be illuminated, thereby increasing the spatial scale at which biological consequences of this light might be considered. Third, in contrast to intermittent bioluminescent light sources in the deep sea, the light emitted at vents almost certainly glows or flickers continuously over the life of the individual black smokers (years to decades); collectively, light emitted from black smokers along the ocean's spreading centers superimposed on background Cerenkov radiation negates the concept of the deep sea as an environment devoid of abiotic light. Finally, the history of hydrothermal activity predates the origin of life; light in the deep sea has been a continuous phenomenon on a geological time scale and may have served either as a seed or refugium for the evolution of biological photochemical reactions or adaptations.

  1. PREFACE: Soil Change Matters International Workshop - Overview

    NASA Astrophysics Data System (ADS)

    MacEwan, R.; Alexander, J.

    2015-07-01

    Soils change in response to land use, land management and climate. Understanding the mechanisms and rates of change in fundamental soil properties, their extent across landscapes, and the drivers of change, is critical for management of soil and land to ensure enduring productivity and the provision of ecosystem services. A reliable evidence base for soil change can be created through research into fundamental soil properties and processes, which coupled with monitoring, can be used to develop models to support management and policy decisions. Soil scientists, land managers and policy makers occupy different intellectual domains and each can contribute to a soil change dialogue focussed on providing the best science for managers, policy and decision-making. Clarity is needed concerning the knowledge needs of policy makers and the latter need to understand what is achievable by science and at what cost. However, communication is often limited by the discipline-specific language used by each group. Facilitated communication would improve the impact of science on policy by enabling scientists to better understand policy maker needs and enabling policy makers to better understand scientific data interpretations, limitations, and gaps. The international workshop 'Soil Change Matters' in Bendigo, Australia 24-27 March 2014, brought together 200 delegates across these intellectual domains to talk to each other, share conclusions, questions and data, and to learn about scenarios for soil change and for soil policies.

    Passive wireless sensors have the advantages of operating without a power supply and remote sensing capability. Hence, they are very suitable for some harsh environments, such as hermetic environments, rotating parts, or very high temperature environments. The spray painting workshop is such a harsh environment, containing a large amount of flammable paint mist and organic gas. Aiming at this special environment of spray painting workshop, a passive wireless hermetic environment monitoring system was designed, fabricated, and demonstrated. The proposed system is composed of a transponder and a reader, and the circuit design of each part is given in detail in this paper. The power and the data transmission between the transponder and the reader are realized by the inductive coupling mechanism. Utilizing the back scatter modulation and channel multiplexing, the frequency signals generated by three different environmental sensors—together with their interfaces in the transponder—are wirelessly read out by the reader. Because of the harsh environment of the spray painting room, the package of the monitoring system is quite important. Three different kinds of filter films for the system package were compared. The experimental results show that the composite filter film aluminum anodic oxide/polytetrafluoroethylene (AAO/PTFE) has the best performance. After fabrication, the measured temperature, humidity, and pressure sensitivities were measured and found to be 180 Hz/°C in the range of 0~60 °C, 100 Hz/%RH in the range of 15~95 %RH, and 42 Hz/hPa in the range of 600~1100 hPa, respectively. Additionally, the remote sensing distance of the monitoring system reaches 4 cm. Finally, the passive wireless hermetic environment monitoring system was installed on the glass wall of the spray painting workshop and was successfully demonstrated. PMID:27490546

    The purpose of this R D planning workshop was to identify and define specific office building industry research that will lead to new and/or improved uses of electricity to provide individual (local) office environment control and increase office worker productivity. The workshop conducted October 11--12, 1988 was the third in a series of meetings held to identify research needs related to office productivity. Participants included experts in the fields of office acoustics, lighting, thermal comfort, air quality, environmental system controls, space planning, automation, and productivity. The first meeting was held May 31--June 1 to broadly define issues related to office productivity research and limitations in existing office environmental systems. A second meeting was held August 22--23 with another group of experts to define the state of the art in office environmental systems and productivity measurement and to begin to identify specific research that could lead to improved systems (and increased productivity). Recommendations from this group became the basis for workshop discussions. The October workshop combined the participants from the first two meetings and added a new group of experts to respond to the conclusions being developed from the earlier work. 3 figs., 2 tabs.

    The Native Peoples-Native Homelands Climate Change Workshop was held on October 28 through November 01,1998, as part of a series of workshops being held around the U.S. to improve the understanding of the potential consequences of climate variability and change for the Nation. This workshop was specifically designed by Native Peoples to examine the impacts of climate change and extreme weather variability on Native Peoples and Native Homelands from an indigenous cultural and spiritual perspective and to develop recommendations as well as identify potential response actions. The workshop brought together interested Native Peoples, representatives of Tribal governments, traditional elders, Tribal leaders, natural resource managers, Tribal College faculty and students, and climate scientists fiom government agencies and universities. It is clear that Tribal colleges and universities play a unique and critical role in the success of these emerging partnerships for decision-making in addition to the important education function for both Native and non-Native communities such as serving as a culturally-appropriate vehicle for access, analysis, control, and protection of indigenous cultural and intellectual property. During the discussions between scientists and policy-makers from both Native and non-Native communities, a number of important lessons emerged which are key to building more effective partnerships between Native and non-Native communities for collaboration and decision-making for a more sustainable future. This talk summarizes the key issues, recommendations, and lessons learned during this workshop.

    Background Pharmacists can play an important role in both the detection of asthma and its monitoring in patients with asthma. Objective To assess the change in asthma knowledge, and associated variables, of pharmacists attending the “Pharmacotherapy follow- up of Adult Bronchial Asthma” workshops run by the Pharmaceutical Care Center of Stada Laboratories. Methods All participants in the “Pharmacotherapy follow-up of Adult Bronchial Asthma” workshops completed a pre-test and a post-test. Those who left the workshop and those who did not complete the tests were not included in the analysis. Tests were scored from 0 to 10, and the change in scores was analyzed. Results Of the 90 participating pharmacists, 79 fulfilled the inclusion criteria. 81% (64) were female, and their average age was 38.8 years [CI95%= 36.65-40.81]. The average pre-test score was 3.65 [CI95%=3.29-4.01]; 72.2% of the pharmacists scored less than 5 points. The average post-test score was 7.33 [CI95%=7.01-7.65]. The average change in scores was 3.68 [CI95%=3.29-4.07]. No statistical significance was found between this change in scores and other variables analyzed (age, gender, previous training, or position in the pharmacy). Conclusion CAF Stada “Adult Bronchial Asthma” workshops increased pharmacists’ general knowledge. PMID:25214901

    Representatives from fifteen countries met in Prague, Czech Republic, on September 11-15, 1995, to share results from the analysis of vulnerability and adaptation to global climate change. The workshop focused on the issues of global climate change and its impacts on various sectors of a national economy. The U.N. Framework Convention on Climate Change (FCCC), which has been signed by more than 150 governments worldwide, calls on signatory parties to develop and communicate measures they are implementing to respond to global climate change. An analysis of a country`s vulnerability to changes in the climate helps it identify suitable adaptation measures. These analyses are designed to determine the extent of the impacts of global climate change on sensitive sectors such as agricultural crops, forests, grasslands and livestock, water resources, and coastal areas. Once it is determined how vulnerable a country may be to climate change, it is possible to identify adaptation measures for ameliorating some or all of the effects.The objectives of the vulnerability and adaptation workshop were to: The objectives of the vulnerability and adaptation workshop were to: Provide an opportunity for countries to describe their study results; Encourage countries to learn from the experience of the more complete assessments and adjust their studies accordingly; Identify issues and analyses that require further investigation; and Summarize results and experiences for governmental and intergovernmental organizations.

    Projections indicate that demand for aviation transportation will increase by more than two fold over the next few decades. Timely action is needed to understand and quantify the potential climate impacts of aviation emissions particularly given the sustained lapse over the last several years in U.S. research activities in this area. In response to the stated needs, Environmental Integrated Product Team of Next Generation Air Transportation System/Joint Planning and Development Office and PARTNER (Partnership for AiR Transportation Noise and Emissions Reduction, FAA/NASA/Transport Canada sponsored Center of Excellence) convened a group of international experts to participate in the "Workshop on the Impacts of Aviation on Climate Change" during June 7-9, 2006 in Boston, MA. The workshop focus was on the impacts of subsonic aircraft emissions in the UT/LS region and on the potential response of the climate system. The goals of the workshop were to assess and document the present state of scientific knowledge, to identify the key underlying uncertainties and gaps, to identify ongoing and further research needed, to explore the development of climate impact metrics, and to help focus the scientific community on the aviation-climate change research needs. The workshop concluded that the major ways that aviation can affect climate, in agreement with the 1999 assessment by the Intergovernmental Panel on Climate Change (IPCC), are the direct climate effects from CO2 and water vapor emissions, the indirect forcing on climate resulting from changes in the distributions and concentrations of ozone and methane as a primary consequence of aircraft nitrogen oxide (NOx) emissions, the direct effects (and indirect effects on clouds) from emitted aerosols and aerosol precursors, and the climate effects associated with contrails and cirrus cloud formation. The workshop was organized in three subgroups: (1) Effects of aircraft emissions on the UT/LS chemical composition, (2) Effects

  8. Does a brief workshop change clinical associate students’ resilience?

    PubMed Central

    2016-01-01

    Background Clinical associates resilience is important as many will work in adverse circumstances. There is some evidence that educational interventions can improve health care student resilience although it is conflicting. There is no previously published research on educational interventions for resilience in clinical associate students. Objective To investigate whether a brief resilience workshop could improve resilience in clinical associate students. Methods A single cohort pre-post design was used. Resilience scores were calculated using the Connor-Davidson 25-item resilience scale in a cohort of clinical associate students before and 8 weeks after a brief resilience workshop. Results Although no statistically significant changes were observed after a brief resilience workshop, this study adds to the existing body of knowledge on resilience in African health care training. Conclusion The evidence for education interventions to improve resilience is conflicting and complex. Given the relevance to health care workers and their educators, interventions to improve resilience should continue to be evaluated and the outcomes should be reported. PMID:27796118

    Americans' consumption of fruits and vegetables has increased slightly over the last 10 years, but most people still do not meet the Dietary Guidelines recommendation to consume 5 to 9 servings per day. New and innovative strategies are needed if we are to significantly increase the mean population intake of fruits and vegetables. To help formulate such strategies as well as to evaluate evidence and identify research gaps, the American Cancer Society and the Centers for Disease Control and Prevention convened the Fruit and Vegetable Environment, Policy, and Pricing Workshop, which brought together experts in how environmental change, policy, and pricing affect fruit and vegetable consumption. The papers in this supplement consist of a review of environmental interventions to improve nutrition and papers covering pricing and consumer value and how fruit and vegetable consumption can be promoted at worksites, restaurants, grocery stores and other community settings, and schools. Conclusions from the workshop were that existing intervention strategies need to be evaluated, promising example programs need to be disseminated, and new innovative interventions and programs need to be created and evaluated.

    2015-01-01

    For change programs to succeed, it is vital to have a detailed understanding of employees' views regarding the program, especially when the proposed changes are potentially contested. Gaining insight into employee perceptions helps managers to decide how to proceed. The authors conducted two workshops in a radiotherapy institute to assess the benefits and drawbacks, as well as their underlying causes, of a proposed Lean change program. Managers' views on the workshops' usefulness were charted. The paper aims to discuss these issues. Two workshops were organized in which employees predicted positive and negative effects of a Lean program. The workshops combined a structured brainstorm (KJ-technique) and an evaluation of the expected effects. Eight top managers judged the workshops' value on supporting decision making. In total, 15 employees participated in the workshops. Participants from workshop 2 reported more expected effects (27 effects; 18 positive) than from workshop 1 (14 effects; six positive). However, when effects were categorized, similar results were shown. Three from eight managers scored the results relevant for decision making and four neutral. Seven managers recommended future use of the instrument. Increased employee involvement and bottom-up thinking combined with relatively low costs were appreciated most. The workshop could serve as a simple instrument to improve decision making and enhance successful implementation of change programs, as it was expected to enhance employees' involvement and was relatively easy to conduct and cheap. The workshop increased insight into employee views, facilitating adaptive actions by healthcare organization managers.

    1992-01-01

    The proceedings of the third Workshop on Change of representation and Problem Reformulation is presented. In contrast to the first two workshops, this workshop was focused on analytic or knowledge-based approaches, as opposed to statistical or empirical approaches called 'constructive induction'. The organizing committee believes that there is a potential for combining analytic and inductive approaches at a future date. However, it became apparent at the previous two workshops that the communities pursuing these different approaches are currently interested in largely non-overlapping issues. The constructive induction community has been holding its own workshops, principally in conjunction with the machine learning conference. While this workshop is more focused on analytic approaches, the organizing committee has made an effort to include more application domains. We have greatly expanded from the origins in the machine learning community. Participants in this workshop come from the full spectrum of AI application domains including planning, qualitative physics, software engineering, knowledge representation, and machine learning.

    This report summarizes outcomes from a two-day scenario planning workshop for Acadia National Park, Maine (ACAD). The primary objective of the workshop was to help ACAD senior leadership make management and planning decisions based on up-to-date climate science and assessments of future uncertainty. The workshop was also designed as a training program, helping build participants' capabilities to develop and use scenarios. The details of the workshop are given in later sections. The climate scenarios presented here are based on published global climate model output. The scenario implications for resources and management decisions are based on expert knowledge distilled through scientist-manager interaction during workgroup break-out sessions at the workshop. Thus, the descriptions below are from these small-group discussions in a workshop setting and should not be taken as vetted research statements of responses to the climate scenarios, but rather as insights and examinations of possible futures (Martin et al. 2011, McBride et al. 2012).

    2011-12-01

    The number of students in sciences is declining and thus it is critical to employ a variety of initiatives to familiarize students with various topics in sciences as well as the university environment. In particular, this is a challenge in rural communities where many students do not have easy access to university campuses. Therefore, we have implemented a workshop for junior and senior high school students. We decided to run this workshop on the campus, as this provided not only exposure of the students to scientific and lecturing facilities, but also to life at the university. Holding the workshop on the university campus also enabled faculty and graduate students from several departments to participate, thus allowing for presentation of a wide variety of topics within atmospheric sciences. Our experiences with the continuously growing workshops - from 50 to 180 participating students - will be shared. Participants were students from both rural and urban areas. These workshops, therefore, contributed to our outreach and service to the local community and to students coming from the rural communities of the upper Midwest and Western states. The workshops are organized annually over the spring break, thus ensuring availability of facilities on the campus. The one-day workshop includes a short cycle of presentations focused on the characterization of atmospheric PM and several critical issues connected with it. The expert faculty members from several departments involved in such research present on global warming, air pollution, aerosol formation, measurement using an aircraft, the relation of emissions and energy production, and on modeling of atmospheric processes. This lecture series (each no longer than 15 min) was broken down by fun demonstrations to break the ice and attract students' attention. Following the presentations, students participated in demonstrations performed in the Chemistry Department. The demonstrations included several hands-on activities

    This volume is a collection of papers associated with a series of invited lectures presented at the First Workshop on Nonequilibrium processes in Plasma Physics and studies of Environment that was held at Mt Kopaonik in August 2006. The workshop originated as a part of the FP6 COE 026328 which had the basic aim of promoting centers of excellence in Western Balkan countries, to facilitate dissemination of their results and to help them establish themselves in the broader arena of European and international science. So the best way to achieve all those goals was to prepare a workshop associated with the local conference SPIG (Symposium on Physics of Ionized Gases) where the participants could attend sessions in which the host Laboratory presented progress reports and papers and thereby gain a full perspective of our results. At the same time this allowed participants in the COE the opportunity to compare their results with the results of external speakers and to gain new perspectives and knowledge. The program of the workshop was augmented by inviting some of our colleagues who visited the COE in recent years or have an active collaboration with a participating member. In that respect this volume is not only a proceedings of the workshop but a collection of papers related to the topic of the workshop: Non-equilibrium phenomena in plasmas and in the science of our environment. The idea is to offer review articles either summarizing a broader area of published or about to be published work or to give overviews showing preliminary results of the works in progress. The refereeing of the papers consisted of two parts, first in selection of the invitees and second in checking the submitted manuscripts. The papers were refereed to the standard of the Journal. As the program of the COE covers a wide area of topics from application of plasmas in nano- electronics to monitoring and removal of pollutants in the atmosphere, so the program of the workshop covered an even broader

    Environmental exposures have been recognized as critical in the initiation and exacerbation of asthma, one of the most common chronic childhood diseases. The National Institute of Allergy and Infectious Diseases; National Institute of Environmental Health Sciences; National Heart, Lung, and Blood Institute; and Merck Childhood Asthma Network sponsored a joint workshop to discuss the current state of science with respect to the indoor environment and its effects on the development and morbidity of childhood asthma. The workshop included US and international experts with backgrounds in allergy/allergens, immunology, asthma, environmental health, environmental exposures and pollutants, epidemiology, public health, and bioinformatics. Workshop participants provided new insights into the biologic properties of indoor exposures, indoor exposure assessment, and exposure reduction techniques. This informed a primary focus of the workshop: to critically review trials and research relevant to the prevention or control of asthma through environmental intervention. The participants identified important limitations and gaps in scientific methodologies and knowledge and proposed and prioritized areas for future research. The group reviewed socioeconomic and structural challenges to changing environmental exposure and offered recommendations for creative study design to overcome these challenges in trials to improve asthma management. The recommendations of this workshop can serve as guidance for future research in the study of the indoor environment and on environmental interventions as they pertain to the prevention and management of asthma and airway allergies.

    In the past few decades, there has been enormous growth in scientific studies of physical, chemical, and biological interactions among reservoirs in polar regions. This has come, in part, as a result of a few significant discoveries: There is dramatic halogen chemistry that occurs on and above the sea ice in the springtime that destroys lower tropospheric ozone and mercury [Simpson et al., 2007; Steffen et al., 2008], the sunlit snowpack is very photochemically active [Grannas et al., 2007], biology as a source of organic compounds plays a pivotal role in these processes, and these processes are occurring in the context of rapidly changing polar regions under climate feedbacks that are as of yet not fully understood [Serreze and Barry, 2011]. Stimulated by the opportunities of the International Polar Year (IPY, 2007-2009), a number of large-scale field studies in both polar environments have been undertaken, aimed at the study of the complex biotic and abiotic processes occurring in all phases (see Figure 1). Sea ice plays a critical role in polar environments: It is a highly reflective surface that interacts with radiation; it provides a habitat for mammals and micro-organisms alike, thus playing a key role in polar trophic processes and elemental cycles; and it creates a saline environment for chemical processes that facilitate release of halogenated gases that contribute to the atmosphere's ability to photochemically cleanse itself in an otherwise low-radiation environment. Ocean-air and sea ice-air interfaces also produce aerosol particles that provide cloud condensation nuclei.

    The Looking for Life in Extreme Environments workshop held at Indiana University Bloomington in July of 2009 was the first in a series of workshops for high-school teachers that are currently in development. The workshops' modules are based on the research of faculty members in the Departments of Geological Sciences, Biology, and Astronomy, the School of Education, and the School of Public and Environmental Affairs at Indiana University Bloomington; the modules use lessons from Exploring Deep-Subsurface Life. Earth Analogues for Possible Life on Mars: Lessons and Activities, curricular materials that were produced and edited by Lisa Pratt and Ruth Droppo and published by NASA in 2008. Exploring Deep-Subsurface Life is a workbook, a DVD (with closed-captioning), and a CD with the lessons in digital text format for adaptation to classroom needs and printing. Each lesson includes the National Education Standards that apply to the materials. The workbook's lessons are written with three considerations: Life Domains, Cellular Metabolism, and Extreme Environments and Microbes. Students are challenged to build, draw, measure, discuss, and participate in laboratory processes and experiments that help them understand and describe microbes and their environments. In the Capstone, the students write a grant proposal based on the three lessons' analogues. The DVD is collection of videotaped interviews with scientists in laboratories at Michigan State, Princeton, and Indiana University, who are working on water and gas samples they collected from deep gold mines in South Africa and the Canadian Arctic. The interview materials and some animated graphics are compiled into four video pieces that support and compliment the accompanying workbook lessons and activities, and offer students insight into the excitement of scientific discovery.

    Reflectance spectrophotometry and polarimetry are major tools in remote sensing studies of surfaces of solar system bodies. The interpretations of such measurements are often based on laboratory studies of meteoritic, lunar, and terrestrial materials. However, the optical properties of regoliths are known to be affected by the space environment. Thus, some of the major questions addressed in the workshop include identity of the soil component responsible for alteration of the optical properties, the process that produced this component, and how reliably the effects of these processes could be extrapolated to other bodies of the solar system.

    1982-06-01

    Environmental pollution is a problem of crisis proportions in today's world, presently more visible in technologically advanced than in the developing countries. Progress and affluence in the technologically developed countries has been achieved at the expense of depletion of natural resources and deterioration of the environment at the global level. Each of the 3 important factors responsible for environmental pollution--population growth, increase in affluence, and industrialization--are reviewed. There are direct and indirect effects of population growth on the environment. Other things being equal, the greater the population, the more significant are the changes brought about in the environment. More people increases demands on food, energy, housing, clothing, and transportation, all of which lead to environmental pollution. Poor quality or insufficiency of food supply, sanitation, water supply, housing, employment, and health and other services are common problems in countries with high rates of population increase. Problems of domestic sewage and solid waste disposal are directly related to the number of people. Economic growth means more consumption of resources. The effect of affluence can possibly be better understood in the context of the problem of food. With the improved economic status of the peole in many countries, the composition of their diet has been changing. Examining the grain requirements in different countries is a way to understand the effect of increased affluence on the demand for food. During 1969-70 the high income countries with 30% of the world population accounting for 51% of the total consumption of cereals. The higher rate of consumption of cereals in the developed countries is due to indirect utilization. Cereals which can be directly consumed by humans are fed to cattle. The per capita amount of direct and indirect grain consumption continues to increase as per capita income climbs. Developing countries, in their anxiety to

    Healthcare professionals are increasingly expected to work in interprofessional teams. Students therefore need opportunities to learn and practise skills that will allow them to be effective team members when they enter the workforce. This article summarises an interprofessional learning experience for 289 undergraduate and graduate students representing 13 programmes in a College of Health Professions (CHP) at a US public university. The half-day workshop provided an opportunity for participants with no prior interprofessional education to collaborate in a problem-solving case study and to inform students of other professions about their professions. Faculty members from all CHP programmes collaborated in writing the case study and facilitating student discussions during the event. Attitudes related to interprofessional collaboration and professional roles were assessed prior to and after workshop participation. A paired t test showed a statistically significant difference in four attitude questions. Participants reported a significant increase in understanding the roles of other professionals in healthcare and community situations. They also reported an increased understanding of the benefits and challenges of working in interprofessional teams. This event successfully introduced participants to interprofessional collaboration and provided them the opportunity to share their professional expertise and understand the expertise of others.

    It is a great pleasure for me to have the honor of delivering the keynote address for this important gathering, an honor enhanced further because of the many activities and historic relationships represented by this workshop. First of all, it represents the spirit of continuing cooperation and good relations between the United States and Japan. With the aid of the framework provided by the U.S./Japan Science and Technology Agreement, our two nations can come together to address a problem that has no national boundaries {hor_ellipsis} and we can think about solutions of potential benefit to all citizens of the global community. This workshop also symbolizes the spirit of cooperation so characteristic of the conduct of research in science and technology -- cooperation between us as individual scientists and engineers, between the various institutions we represent, and across our diverse disciplines. This workshop is only the second of its kind. The first US/Japan Workshop on global climate change was held last year in Japan. That workshop focused on cooperative scientific research in the United States and Japan. Out of it came a general agreement to continue collaborative work and to extend cooperation into the area of global change-related technologies, in particular those technologies that hold promise for mitigation and adaptation.

  7. Managing change in a changing environment.

    PubMed

    Bruning, L

    1993-01-01

    Change comes from different directions and must be managed in different ways. Change may come from the top down (eg, from parents to children) or from the bottom up (eg, from staff to management). Introduced change is initiated by you; imposed change is initiated by someone else. Change is necessary to move forward and remain effective. If change is resisted, there is the risk of becoming complacent, outdated, or obsolete. There is no room for obsolescence in health care. Even under the best of circumstances, change will be met with resistance. To overcome resistance, involve people in planning for the change and ensure understanding through verbal and written communications. Be prepared to revise the plan, and always remain flexible.

    The Workshop was successful in achieving its main objective of identifying a large number of technical issues relating to the design of two-phase systems for space applications. The principal concern expressed was the need for verified analytical tools that will allow an engineer to confidently design a system to a known degree of accuracy. New and improved materials, for such applications as thermal storage and as heat transfer fluids, were also identified as major needs. In addition to these research efforts, a number of specific hardware needs were identified which will require development. These include heat pumps, low weight radiators, advanced heat pipes, stability enhancement devices, high heat flux evaporators, and liquid/vapor separators. Also identified was the need for a centralized source of reliable, up-to-date information on two-phase flow in a space environment.

    Climate Change Impacts and Adaptation: NASA Mission and Infrastructure; Kennedy Space Center, Florida, 28-30 July 2009; With centers located throughout the country, NASA could experience a range of climate change hazards. Depending on the region, these hazards are likely to include more extreme and frequent high temperatures, more frequent and intense precipitation events, changing water availability, and sea level rise. These changing climate hazards could undermine key NASA missions by damaging operations and critical infrastructure assets. The specific effects of climate change may include shifting availability, reliability, and cost of water and energy; and changes in safety and operations related to more extreme events (e.g., floods, fire).

  5. Advancing Women Scientists: Exploring a Theoretically Grounded Climate Change Workshop Model

    NASA Astrophysics Data System (ADS)

    Silver, Barbara; Prochaska, Janice; Mederer, Helen; Harlow, Lisa; Sherman, Karen

    Universities in the United States have an increasing need to recruit the best and the brightest faculty to remain globally competitive, but the majority of schools share a profile that includes a low percentage of women in most of the science, technology, engineering, and math (STEM) disciplines. Changes in university culture are needed to enable departmental diversity growth, to expand offerings and perspectives, and to strengthen the view that STEM is an attractive choice for female students and prospective faculty. This paper describes the theoretical models used to develop a prototype workshop series implemented in departments to help faculty progress in their readiness to advance women scientists, defined as collaborating, mentoring, sharing resources, and generating support through community. The three theoretical underpinnings are the gender-as-structure theory of organizational change, Appreciative Inquiry, and the Transtheoretical Model. These workshops are one aspect of the climate change efforts implemented by the ADVANCE program of the University of Rhode Island.

    A variety of Florida-focused climate change activities will be featured as part of the ASK Florida global and regional climate change professional development workshops. In a combined effort from Florida State University's Center for Ocean-Atmospheric Prediction Studies (COAPS) and University of South Florida's Coalition for Science Literacy (CSL), and supported by NASA's NICE initiative, the ASK Florida professional development workshops are a series of workshops designed to enhance and support climate change information and related pedagogical skills for middle school science teachers from Title-I schools in Florida. These workshops took place during a two-year period from 2011 to 2013 and consisted of two cohorts in Hillsborough and Volusia counties in Florida. Featured activities include lab-style exercises demonstrating topics such as storm surge and coastal geometry, sea level rise from thermal expansion, and the greenhouse effect. These types of labs are modified so that they allow more independent, inquiry thinking as they require teachers to design their own experiment in order to test a hypothesis. Lecture based activities are used to cover a broad range of topics including hurricanes, climate modeling, and sink holes. The more innovative activities are group activities that utilize roll-playing, technology and resources, and group discussion. For example, 'Climate Gallery Walk' is an activity that features group discussions on each of the climate literacy principles established by the United States Global Change Research Program. By observing discussions between individuals and groups, this activity helps the facilitators gather information on their previous knowledge and identify possible misconceptions that will be addressed within the workshops. Furthermore, 'Fact or Misconception' presents the challenge of identifying whether a given statement is fact or misconception based on the material covered throughout the workshops. It serves as a way to

  7. A Seismic Shift: Evaluating Changes in Scientists' Attitudes Regarding Journalists and Science Communication After Media Workshops

    McBride, S.; Herbulock, D.

    2015-12-01

    Providing natural hazards scientists the opportunity to question and engage directly with journalists in a workshop setting proved effective at shifting scientists' attitudes on their role in media and public communication during natural disasters. Scientists surveyed after the encounter expressed a more responsive attitude to communicating during crises, increased willingness to support scientific peers' communication efforts and more realistic perspectives on journalists' needs and objectives. Geoscientists experienced unprecedented and intensive media and public scrutiny during the Canterbury, New Zealand earthquakes of 2010-2012. Following major quakes and aftershocks, there was a sustained high level of public demand for information and expert analysis of the underlying geological events and ongoing hazards and risks. Once the crisis ended, a period of reflection gave rise to understanding of the need for further media and communication training amongst natural hazards scientists. A workshop designed to explore scientists' attitudes to public communication during disasters and challenge their views on media, press offices and the expectations of the public was developed and implemented by the Science Media Centre, New Zealand and Massey University. This research was developed as an evaluation of this workshop. Quantitative analysis with some qualititive analysis were the methods used. Some findings include: a shift in how journalists were perceived by scientists after the workshop, largely influenced by perspectives shared during a panel where invited journalists reflected on their own experiences and answered questions from scientists. discussions on different spokespeople from different science institutions contributing to the public discussion showed a change in perception from a preference for one central spokesperson to increased support for a variety of perspectives from multiple scientists. This was influenced by insight provided by journalists during

    Climate change with global warming is a physicometeorological fact that, among other aspects, will also affect human health. Apart from cardiovascular and infectious diseases, allergies seem to be at the forefront of the sequelae of climate change. By increasing temperature and concomitant increased CO(2) concentration, plant growth is affected in various ways leading to prolonged pollination periods in the northern hemisphere, as well as to the appearance of neophytes with allergenic properties, e.g. Ambrosia artemisiifolia (ragweed), in Central Europe. Because of the effects of environmental pollutants, which do not only act as irritants to skin and mucous membranes, allergen carriers such as pollen can be altered in the atmosphere and release allergens leading to allergen-containing aerosols in the ambient air. Pollen has been shown not only to be an allergen carrier, but also to release highly active lipid mediators (pollen-associated lipid mediators), which have proinflammatory and immunomodulating effects enhancing the initiation of allergy. Through the effects of climate change in the future, plant growth may be influenced in a way that more, new and altered pollens are produced, which may affect humans.

  9. Teaching about Climate Change and Energy with Online Materials and Workshops from On the Cutting Edge

    Global climate change and energy use are among the most relevant and pressing issues in today’s science curriculum, yet they are also complex topics to teach. The underlying science spans multiple disciplines and is quickly evolving. Moreover, a comprehensive treatment of climate change and energy use must also delve into perspectives not typically addressed in geosciences courses, such as public policy and economics. Thus, faculty attempting to address these timely issues face many challenges. To support faculty in teaching these subjects, the On the Cutting Edge faculty development program has created a series of websites and workshop opportunities to provide faculty with information and resources for teaching about climate and energy. A web-based collection of teaching materials was developed in conjunction with the On the Cutting Edge workshops “Teaching about Energy in Geoscience Courses: Current Research and Pedagogy.” The website is designed to provide faculty with examples, references and ideas for either incorporating energy topics into existing geoscience courses or for designing or refining a course about energy. The website contains a collection of over 30 classroom and lab activities contributed by faculty and covering such diverse topics as renewable energy, energy policy and energy conservation. Course descriptions and syllabi for energy courses address audiences ranging from introductory courses to advanced seminars. Other materials available on the website include a collection of visualizations and animations, a catalog of recommended books, presentations and related references from the teaching energy workshops, and ideas for novel approaches or new topics for teaching about energy in the geosciences. The Teaching Climate Change website hosts large collections of teaching materials spanning many different topics within climate change, climatology and meteorology. Classroom activities highlight diverse pedagogic approaches such as role

  15. Impediments to Data Discovery in a Distributed Environment: A Workshop Report

    2006-12-01

    Data discovery is often compartmentalized into discovery at the "catalog" level - high level, broad descriptions of data sets or collections - and discovery at the "inventory" level - detailed listings of granules in data sets. The catalog and inventory levels are also generally viewed as distinct from the data level, where the actual data granules reside. With an increase in on-line access to data such as that offered by OPeNDAP, WFS, WCS and WMS, there has been an increase in interest in discovery capabilities that provide the data, or lists of URLs for the data, meeting a variety of search criteria - in other words, a seamless capability to find and retrieve data of interest. In order to address issues related to discovery in a distributed environment, a workshop was held in May 2006 at Unidata/UCAR in Boulder, Colorado. Participants were drawn from 8 organizations dealing with various issues related to data discovery. The workshop began with the description of a number of different data discovery capabilities, including ECHO, GCMD, THREDDS, and ADL. This was followed by the analysis of two case studies with specific attention given to the ability, or lack thereof, of current data discovery components to find data relevant to the case studies. Several key findings resulted from this analysis which, although obvious in retrospect, we believe to be major deficiencies in the way data discovery is being approached today. These findings are: There is no consistency in the inventorying of data. Links between the catalog, inventory and data levels are tenuous at best; moving from the catalog to the inventory level and from the inventory to the data level is tedious at best. There is little to no consistency in the access protocols that are used by data discovery components. This is especially true at the inventory level. These findings suggest that the level of effort involved in finding data of interest could be substantially reduced by either reducing the number of

    The National Institute on Alcohol Abuse and Alcoholism (NIAAA) sponsored a May 2002 workshop on gene-environment interaction (G x E) research to identify potential roadblocks to further research and to propose solutions to those roadblocks, to optimize investigative opportunities and multidisciplinary or multi-institution collaborations, and to explore ways that NIAAA can facilitate G x E studies. Sessions included panels on animal models; phenotypes; genetic findings in humans; study designs and analytical methods; and assessment of environmental risk. Key among the identified challenges to progress in G x E research were issues of study design and sampling strategies; logistic and methodological costs and constraints; availability and understanding of data analysis techniques; potential stigmatization of study populations; and organizational/bureaucratic structures that are inadequate to address the unique needs of large-scale, multicenter, longitudinal projects. Participants proposed a series of recommendations to address these issues. Session coordinators included: Gayle Boyd, Kendall Bryant, Page Chiapella, Vivian Faden, David Goldman, and Antonio Noronha. Session participants included: Laura Almasy, Henri Begleiter, Raul Caetano, Bruce Dudek, Mary Dufour, Cindy Ehlers, Mary-Anne Enoch, Joel Gelernter, David Goldman, Bridget Grant, Lorraine Gunzerath, Deborah Hasin, Andrew Heath, Victor Hesselbrock, J.

    On July 13th 2006 during the triannual Unidata Workshop, members of the Unidata community got their first experience with capabilities being developed under the Linked Environments for Atmospheric Discovery (LEAD) project (see: http://lead.ou.edu). The key LEAD goal demonstrated during the workshop was that of "Democratization," that is, providing capabilities that typically have a high barrier to entry to the larger meteorological community. At the workshop, participants worked with software that demonstrated the specific concepts of: 1) Lowering the barrier to entry by making it easy for users to: - Experiment using meteorological tools - Create meteorological forecasts - Perform mesoscale modeling and forecasting - Access data (source and product) - Make use of large scale cyberinfrastructure (E.g. TeraGrid) 2) Giving users the freedom from technological issues such as: - Hassle-free access to supercomputing resources - Hassle-free execution of forecast models and related tools - Data format independence This talk will overview the capabilities presented to the Unidata workshop participants as well as capabilities developed since the workshop. There will also be a lessons-learned section. This overview will be accomplished with a live demonstration of some of the capabilities. Capabilities that will be discussed and demonstrated have applicability across many disciplines e.g. discovering, acquiring and using data and orchestrating of complex workflow. Acknowledgement: The LEAD project involves the work of nearly 100 individuals whose dedication has resulted in the capabilities that will be shown here.

    1988-12-01

    A workshop was convened to define key issues regarding the impacts of climatic variability on the performance of protective layered soil and rock barriers proposed for possible use at Hanford. Workshop participants concluded that the sensitivity of vegetation and evapotranspiration to climate must be better understood before climate-change impacts on drainage through the barrier and groundwater recharge can be adequately modeled. As a result of this conclusion, workshop participants proposed measuring evapotranspiration and other water balance parameters in lysimeters constructed around monoliths of undisturbed soil and mature vegetation, and located at sites analogous to late-Quaternary pluvial and altithermal conditions. Climate-analog sites would be selected based on reconstructions of late-Quaternary vegetational patterns and model projections of future climatic variability in the region. The lysimeter data would be input into a simulation model of soil-water movement in barriers. The distribution of pedogenic carbonates and radionuclides from nuclear weapons testing fallout would be analyzed as independent indicators of past water movement in analog-site soil profiles. 11 refs., 3 figs., 1 tab.

    This document presents the proceedings from the American Thoracic Society Climate Change and Respiratory Health Workshop that was held on May 15, 2010, in New Orleans, Louisiana. The purpose of the one-day meeting was to address the threat to global respiratory health posed by climate change. Domestic and international experts as well as representatives of international respiratory societies and key U.S. federal agencies convened to identify necessary research questions concerning climate change and respiratory health and appropriate mechanisms and infrastructure needs for answering these questions. After much discussion, a breakout group compiled 27 recommendations for physicians, researchers, and policy makers. These recommendations are listed under main issues that the workshop participants deemed of key importance to respiratory health. Issues include the following: (1) the health impacts of climate change, with specific focus on the effect of heat waves, air pollution, and natural cycles; (2) mitigation and adaptation measures to be taken, with special emphasis on recommendations for the clinical and research community; (3) recognition of challenges specific to low-resource countries when coping with respiratory health and climate change; and (4) priority research infrastructure needs, with special discussion of international needs for cooperating with present and future environmental monitoring and alert systems.

    Although it is recognized that many common complex diseases are a result of multiple genetic and environmental risk factors, studies of gene-environment interaction remain a challenge and have had limited success to date. Given the current state-of-the-science, NIH sought input on ways to accelerate investigations of gene-environment interplay in health and disease by inviting experts from a variety of disciplines to give advice about the future direction of gene-environment interaction studies. Participants of the NIH Gene-Environment Interplay Workshop agreed that there is a need for continued emphasis on studies of the interplay between genetic and environmental factors in disease and that studies need to be designed around a multifaceted approach to reflect differences in diseases, exposure attributes, and pertinent stages of human development. The participants indicated that both targeted and agnostic approaches have strengths and weaknesses for evaluating main effects of genetic and environmental factors and their interactions. The unique perspectives represented at the workshop allowed the exploration of diverse study designs and analytical strategies, and conveyed the need for an interdisciplinary approach including data sharing, and data harmonization to fully explore gene-environment interactions. Further, participants also emphasized the continued need for high-quality measures of environmental exposures and new genomic technologies in ongoing and new studies. PMID:21308768

  5. Climate Change Adaptation in the Urban Environment

    Wilbanks, Thomas J

    2011-01-01

    This overview chapter considers five questions that cut across the four case studies in the section to follow: (1) why are urban environments of particular interest; (2) what does an 'urban environment' mean as a focus for adaptation actions, (3) what do we know about climate change vulnerabilities and adaptation potentials in urban areas; (4) what can we expect in the future with adaptation in urban areas; and (5) what is happening with climate change adaptation in urban areas? After decades of inattention, adaptation to risks and impacts of climate change is now receiving long overdue attention, and it is only natural that a considerable share of this attention is focused on the places where most people live. This section considers climate change adaptation in the urban environment, defined as settings where human populations cluster - generally implying relatively large clusters, but not excluding smaller settlements that operate as coherent geopolitical and economic entities. Consistent with the topic of the book, the emphasis of this overview will be on urban environments in developed countries, but it will also draw on knowledge being developed from urban experiences across the globe.

  7. Probabilistic adaptation in changing microbial environments

    Springer, Michael

    Microbes growing in animal host environments face fluctuations that have elements of both randomness and predictability. In the mammalian gut, fluctuations in nutrient levels and other physiological parameters are structured by the host’s behavior, diet, health and microbiota composition. Microbial cells that can anticipate environmental fluctuations by exploiting this structure would likely gain a fitness advantage (by adapting their internal state in advance). We propose that the problem of adaptive growth in structured changing environments, such as the gut, can be viewed as probabilistic inference. We analyze environments that are “meta-changing”: where there are changes in the way the environment fluctuates, governed by a mechanism unobservable to cells. We develop a dynamic Bayesian model of these environments and show that a real-time inference algorithm (particle filtering) for this model can be used as a microbial growth strategy implementable in molecular circuits. The growth strategy suggested by our model outperforms heuristic strategies, and points to a class of algorithms that could support real-time probabilistic inference in natural or synthetic cellular circuits.

  8. Managing change within the healthcare environment.

    Lipcamon, James D

    2003-01-01

    In the healthcare environment, there are many catalysts for change, including federal and state regulations, increased utilization, patients' expectations, competition, declining reimbursement and the technologist shortage. Regardless of what organization you work in, change creates pressure internally. This is especially true of organizations that have not had to deal with much change. The three most common responses are: 1) senior managers tend to isolate themselves from the effects of change on staff members; 2) middle managers tend to feel squeezed between the need to implement change and the need to support staff members; and 3) employees tend to feel attacked and betrayed by change. The following five steps will help you work with your staff as you introduce and implement change: prepare your employees, plan thoroughly, develop a transitional line of authority, stay flexible during implementation, and encourage self-management, acknowledging those who helped make the change work. When change is implemented, it is important to understand that people will move through four stages of reaction: denial, resistance, exploration and commitment. As a general rule, individuals will go through all four stages, but the speed at which they move through them will be different. Managers need to assist employees who get stuck in certain stages. To implement change as successfully as possible, follow these four steps: communicate about change, deal with resistance, increase team involvement, and use visionary leadership.

    The purposes of this study were to describe how a move into a new hospital influenced the work environment, how long it takes clinicians to adjust to such a significant change, and how much a new hospital work environment helps the practice shift toward patient- and family-centered care (PFCC). Creating a healthy work environment to keep patients safe and staff engaged in the mission of the organization is perhaps one of the most important roles of hospital administrators and nursing leaders. A descriptive and comparative design was used to investigate how clinicians perceive, evaluate, and adjust to a new hospital environment, and how much a healthy work environment helps the practice shift toward patient- and family-centered care. Perceived stress was significantly higher than baseline 15 months after the move into the new hospital (p < 0.0000), and employees with 3 or more years of service had significantly higher stress than others (p < 0.000). Nurses had the second lowest mean stress score (x = 12.5). The PFCC score increased significantly (p < 0.007). The single-patient room model increased the workload of many clinicians, and their stress increased after 15 months. There were additional burdens not measured that also may have added to the stress of the participants. The new hospital enabled a significant practice shift toward PFCC.

  12. An evolution of cooperation in changing environment

    NASA Astrophysics Data System (ADS)

    Amirjanov, Adil

    The paper modeled an evolution of cooperation in changing environment. A cooperation model of the evolving population was used. In this model, the individuals base the decisions to donate their resources solely on the similarity of evolved “tags” which are relative to evolved tag-difference tolerances. Two options of the cooperation model were analyzed with constant and random alterations of receiver’s and donor’s resources that change as a result of an interaction between the individuals. In both options of the cooperation model, the average of resources and the average cooperation rate follow the environmental changes, but in different ways. A comparison of the two models makes it evident that a common period of an adaptation for the changing environment is significantly greater for a cooperation model with constant alterations of the donor’s and the receiver’s resources than for a cooperation model with random alterations of them. Quantitative evaluation of the models to assess the influence of an environment on an evolution of cooperation is also provided.

    This is the first of seven papers resulting from a Society of Environmental Toxicology and Chemistry (SETAC) international workshop titled “The Influence of Global Climate Change on the Scientific Foundations and Applications of Environmental Toxicology and Chemistry.” The workshop involved 36 scientists from 11 countries and was designed to answer the following question: How will global climate change influence the environmental impacts of chemicals and other stressors and the way we assess and manage them in the environment? While more detail is found in the complete series of articles, some key consensus points are as follows: (1) human actions (including mitigation of and adaptation to impacts of global climate change [GCC]) may have as much influence on the fate and distribution of chemical contaminants as does GCC, and modeled predictions should be interpreted cautiously; (2) climate change can affect the toxicity of chemicals, but chemicals can also affect how organisms acclimate to climate change; (3) effects of GCC may be slow, variable, and difficult to detect, though some populations and communities of high vulnerability may exhibit responses sooner and more dramatically than others; (4) future approaches to human and ecological risk assessments will need to incorporate multiple stressors and cumulative risks considering the wide spectrum of potential impacts stemming from GCC; and (5) baseline/reference conditions for estimating resource injury and restoration/rehabilitation will continually shift due to GCC and represent significant challenges to practitioners.

    Uncertainty is present in all fields of climate research, spanning from projections of future climate change, to assessing regional impacts and vulnerabilities, to adaptation policy and decision-making. In addition to uncertainties, managers and planners in many sectors are often confronted with large amounts of information from climate change research whose complex and interdisciplinary nature make it challenging to incorporate into the decision-making process. An overarching issue in tackling this problem is the lack of institutionalized dialogue between climate researchers, decision-makers and user groups. Forums that facilitate such dialogue would allow climate researchers to actively engage with end-users and researchers in different disciplines to better characterize uncertainties and ultimately understand which ones are critically considered and incorporated into decisions made. We propose that the introduction of students to these challenges at an early stage of their education and career is a first step towards improving future dialogue between climate researchers, decision-makers and user groups. To this end, we organized a workshop at the University of Zurich, Switzerland, entitled "Uncertainty in Decision Making in a Changing Climate". It brought together 50 participants, including Bachelor, Master and PhD students and academic staff, and nine selected speakers from academia, industry, government, and philanthropy. Speakers introduced participants to topics ranging from uncertainties in climate model scenarios to managing uncertainties in development and aid agencies. The workshop consisted of experts' presentations, a panel discussion and student group work on case studies. Pedagogical goals included i) providing participants with an overview of the current research on uncertainty and on how uncertainty is dealt with by decision-makers, ii) fostering exchange between practitioners, students, and scientists from different backgrounds, iii) exposing

    1993-10-01

    Path planning needs to be fast to facilitate real-time robot programming. Unfortunately, current planning techniques are still too slow to be effective, as they often require several minutes, if not hours of computation. To overcome this difficulty, we present an adaptive algorithm that uses previous experience to speed up future performance. It is a learning algorithm suitable for incrementally-changing environments such as those encountered in manufacturing of evolving products and waste-site remediation. The algorithm extends our previous work for stationary environments in two directions: For minor environmental change, an object-attached experience abstraction scheme is introduced to increase the flexibility of the learned experience; for major environmental change, an on-demand experience repair scheme is also introduced to retain those experiences that remain valid and useful. In addition to presenting this algorithm, we identify three other variants with different repair strategies. To compare these algorithms, we develop an analytic model to compare the costs and benefits of the corresponding repair processes. Using this model, we formalize the concept of incremental change, and prove the optimality of our proposed algorithm under such change. Empirically, we also characterize the performance curve of each variant, confirm our theoretical optimality results, and demonstrate the practicality of our algorithm.

    The environments in which animals have evolved and live have profound effects on all aspects of their biology. Predictable rhythmic changes in the physical environment are arguably among the most important forces shaping the evolution of behavior and physiology of animals, and to anticipate and prepare for these predictable changes animals have evolved biological clocks. Unpredictable changes in the physical environment have important impacts on animal biology as well. The ability of animals to cope with and survive unpredictable perturbations depends on phenotypic plasticity and/or microevolution. From the time metazoans first evolved from their protistan ancestors they have lived in close association with a diverse array of microbes that have influenced, in some way, all aspects of the evolution of animal structure, function and behavior. Yet, few studies have addressed whether daily or seasonal rhythms may affect, or be affected by, an animal’s microbial symbionts. This survey highlights how biologists interested in the ecological and evolutionary physiology of animals whose lifestyles are influenced by environmental cycles may benefit from considering whether symbiotic microbes have shaped the features they study.

    The predicted future of the global marine environment, as a combined result of forcing due to climate change (e.g. warming and acidification) and other anthropogenic perturbation (e.g. eutrophication), presents a challenge to the sustainability of ecosystems from tropics to high latitudes. Among the various associated phenomena of ecosystem deterioration, hypoxia can cause serious problems in coastal areas as well as oxygen minimum zones in the open ocean (Diaz and Rosenberg 2008 Science 321 926-9, Stramma et al 2008 Science 320 655-8). The negative impacts of hypoxia include changes in populations of marine organisms, such as large-scale mortality and behavioral responses, as well as variations of species distributions, biodiversity, physiological stress, and other sub-lethal effects (e.g. growth and reproduction). Social and economic activities that are related to services provided by the marine ecosystems, such as tourism and fisheries, can be negatively affected by the aesthetic outcomes as well as perceived or real impacts on seafood quality (STAP 2011 (Washington, DC: Global Environment Facility) p 88). Moreover, low oxygen concentration in marine waters can have considerable feedbacks to other compartments of the Earth system, like the emission of greenhouse gases to the atmosphere, and can affect the global biogeochemical cycles of nutrients and trace elements. It is of critical importance to prediction and adaptation strategies that the key processes of hypoxia in marine environments be precisely determined and understood (cf Zhang et al 2010 Biogeosciences 7 1-24).

    The C3P &. NASA International Workshop on Environment and Alternative Energy was held on November 15-18, 2011 at the European Space Agency (ESA)'s Research and Technology Centre (ESTEC) in Noordwijk, The Netherlands. The theme of the workshop was "Global Collaboration in Environmental and Alternative Energy Strategies". The workshop was held at ESTEC's conference center. More than 110 individuals from eleven countries attended the workshop. For the first time since the inception of NASA-C3P workshops, a full day was dedicated to a student session. Fifteen students from around the globe gave oral presentations along with poster displays relating to the latest technologies in environmental and alternative energy strategies. Judges from NASA, C3P and ESA awarded plaques to the top three students. In addition to the students, thirty eight U.S. and international subject matter experts presented on the following general environmental-related topics: (1) Hazardous materials management and substitution in support of space operations (2) Emerging renewable and alternative energy technologies (3) Sustainable development and redevelopment (4) Remediation technologies and strategies The workshop also included a panel discussion on the topic of the challenges of operating installations across borders. Throughout the workshop, attendees heard about the scope of environmental and energy challenges that industry and governments face. They heard about technologies for increasing energy efficiency and increasing use of renewable energy. They learned about ways companies and government agencies are using materials, processes, goods and services in a manner more respectful with the environment and in compliance with health and safety rules. The concept of partnerships and their inherent benefits was evidenced throughout the workshop. Partnering is a key aspect of sustainability because sustainable development is complicated. Through formal presentations and side discussions, attendees

    This research is an in-depth study of an environment-based education (EBE) professional development program titled "Creeks and Kids" that models how to employ thematic instruction about watersheds using the environment of a school and its community as a context to integrate teaching and learning about water across core subject areas. This case study investigates the EBE characteristics of the Creeks and Kids Workshop and explores how they adhere to the National Research Council's Standards for Professional Development for Teachers of Science. A mixed-methods analysis gathered qualitative data about the overall experience of teacher-participants during the Creeks and Kids Workshop and employed quantitative measures to identify evidence of success related to teachers' gains in knowledge, affect, confidence and intent to act to implement water-focused EBE curriculum in their classrooms. The findings of the study build upon existing research about what teachers need to implement EBE and their beliefs regarding what professional development should provide in relation to those needs. Qualitative results revealed that teachers need an EBE professional development program to include: 1) practical ways to integrate environmental education into their existing curricula and school settings; and, 2) direct experience with activities and field studies that are interdisciplinary, hands-on and inquiry-driven. Teacher-participants identified these characteristics as vital for them to effect a change in teaching practice and build their confidence to engage their students in EBE when they return to the classroom. Quantitative results revealed statistically significant gains across knowledge, affect, confidence and intent to act variables using the t-test statistic to compare means of participants' responses from the pre- to post-workshop questionnaires. The results of this study have broader implications for future educational research on: 1) the ways in which EBE professional

    Path planning needs to be fast to facilitate real-time robot programming. Unfortunately, current planning techniques are still too slow to be effective, as they often require several minutes, if not hours of computation. To overcome this difficulty, we present an adaptive algorithm that uses past experience to speed up future performance. It is a learning algorithm suitable for incrementally-changing environments such as those encountered in manufacturing of evolving products and waste-site remediation. The algorithm allows the robot to adapt to its environment by having two experience manipulation schemes: For minor environmental change, we use an object-attached experience abstraction scheme to increase the flexibility of the learned experience; for major environmental change, we use an on-demand experience repair scheme to retain those experiences that remain valid and useful. Using this algorithm, we can effectively reduce the overall robot planning time by re-using the computation result for one task to plan a path for another.

    This is the first of seven papers resulting from a Society of Environmental Toxicology and Chemistry (SETAC) international workshop titled “The Influence of Global Climate Change on the Scientific Foundations and Applications of Environmental Toxicology and Chemistry.” The workshop involved 36 scientists from 11 countries and was designed to answer the following question: How will global climate change influence the environmental impacts of chemicals and other stressors and the way we assess and manage them in the environment? While more detail is found in the complete series of articles, some key consensus points are as follows: (1) human actions (including mitigation of and adaptation to impacts of global climate change [GCC]) may have as much influence on the fate and distribution of chemical contaminants as does GCC, and modeled predictions should be interpreted cautiously; (2) climate change can affect the toxicity of chemicals, but chemicals can also affect how organisms acclimate to climate change; (3) effects of GCC may be slow, variable, and difficult to detect, though some populations and communities of high vulnerability may exhibit responses sooner and more dramatically than others; (4) future approaches to human and ecological risk assessments will need to incorporate multiple stressors and cumulative risks considering the wide spectrum of potential impacts stemming from GCC; and (5) baseline/reference conditions for estimating resource injury and restoration/rehabilitation will continually shift due to GCC and represent significant challenges to practitioners.

    The 6(th) COSTAM/SFRR (ASEAN/Malaysia) workshop, "Micronutrients, Oxidative Stress, and the Environment," was held from June 29 to July 2 at Holiday Inn Damai Beach Resort in Kuching, Sarawak. Two hundred twenty participants from 17 countries presented recent advances on natural antioxidants in the area of oxidative stress and molecular aspects of nutrition. Natural products and research are an important program in academic institutions and are experiencing unprecedented interest and growth by the scientific community and public health authorities. Progress is being driven by better understanding of the molecular mechanisms of the relation between oxidative stress and micronutrient action. The gathering of scientists from around the world was fruitful, and we hope that future work will be developed by the formal and informal interactions that took place in this beautiful tropical setting.

    The struggle to develop quality management concepts that ``map`` onto the cultural and work practices found in basic and applied research environments has been (for better or for worse) an attempt to differentiate basic and applied research from the nuclear industry. In the first (1990) edition of this ``Music Book`` proceedings, almost every laboratory that participated had a quality program that was traceable to, based on, influenced by, or in reaction to the nuclear quality standard ASME-NQA-1. This 1993 edition of the ``Music Book`` is very different in that almost every laboratory has developed a quality program that is based on, traceable to, or heavily influenced by DOE 5700.6C (Quality Assurance) and the DOE Standard; Implementation Guide for Quality Assurance Programs for Basic and Applied Research (DOE-ER-STD-6001-92). In order to construct a context for what follows and properly introduce the contents of this book, we want to briefly recount some of the highlights of the events that brought about this change, from the perspective of one who participated in the process.

    The National Council for Science and the Environment (NCSE) held its 15th National Conference and Global Forum on Science, Policy and the Environment: Energy and Climate Change, on January 27-29, 2015, at the Hyatt Regency Hotel, Crystal City, VA. The National Conference: Energy and Climate Change developed and advanced partnerships that focused on transitioning the world to a new “low carbon” and “climate resilient” energy system. It emphasized advancing research and technology, putting ideas into action, and moving forward on policy and practice. More than 900 participants from the scientific research, policy and governance, business and civil society, and education communities attended. The Conference was organized around four themes: (1) a new energy system (including energy infrastructure, technologies and efficiencies, changes in distribution of energy sources, and low carbon transportation); (2) energy, climate and sustainable development; (3) financing and markets; and (4) achieving progress (including ideas for the 21st Conference of Parties to the United Nations Framework Convention on Climate Change). The program featured six keynote presentations, six plenary sessions, 41 symposia and 20 workshops. Conference participants were involved in the 20 workshops, each on a specific energy and climate-related issue. The workshops were designed as interactive sessions, with each workshop generating 10-12 recommendations on the topic. The recommendations were prepared in the final conference report, were disseminated nationally, and continue to be available for public use. The conference also featured an exhibition and poster sessions. The National Conference on Energy and Climate Change addressed a wide range of issues specific to the U.S. Department of Energy’s programs; involved DOE’s scientists and program managers in sessions and workshops; and reached out to a broad array of DOE stakeholders.

  19. An efficient hybrid planner in changing environments

    1993-11-01

    In this paper, we present a new hybrid motion planner than is capable of exploiting previous planning episodes when confronted with new planning problems. Our approach is applicable when several (similar) problems are successively posed for the same static environment, or when the environment changes incrementally between planning episodes. At the heart of our system lie two low-level motion planners: a fast, but incomplete planner (which we call LOCAL), and a computationally costly (possibly resolution) complete planner (which we call GLOBAL). When a new planning problem is presented to our planner, a meta-level planner (which we call MANAGER) decomposes the problem into segments that are amenable to solution by LOCAL. This decomposition is made by exploiting a task graph, in which successful planning episodes have been recorded. In cases where the decomposition fails, GLOBAL is invoked. The key to our planner`s success is a novel representation of solution trajectories, in which segments of collision-free paths are associated with the boundary of nearby obstacles.

    Here we report on a structured decision making (SDM) process to identify management strategies to ensure persistence of the federally endangered Shenandoah salamander (Plethodon shenandoah), given that it may be at increased extinction risk under projected climate change. The focus of this report is the second of two SDM workshops; in the first workshop, participants developed a prototype of the decision, including problem frame, management objectives and a suite of potential management strategies, predictive models to inform the decision and link alternatives with the objectives to identify potential solutions, and identified data needs to reduce key uncertainties in the decision. Participants in this second workshop included experts in National Park Service policy at multiple administrative levels, who refined objectives, further evaluated the initial management alternatives, and discussed policy constraints on implementing active management for the species and its high-elevation habitat. The conclusion of the second workshop was similar to that of the first: the current state of information and objectives suggest that there is some value in considering active management to reduce the long-term extinction risk for the species, though there are institutional conservative policies to implementing active management at range-wide scales. The workshop participants also emphasized a conservative NPS management philosophy, including caution in implementing management actions that may ultimately harm the system, a stated assumption that ecosystem changes were “natural” unless demonstrated otherwise (therefore not warranting active management to mitigate), and a need to demonstrate that extinction risk is tied to anthropogenic influence prior to taking active management to mitigate specific anthropogenic influences. Even within a protected area having minimal human disturbance, intertwined environmental variables and interspecific relationships that drive population

    The EU FP6 HENVINET project reviewed the potential relevance of a focus on climate change related health effects for climate change policies at the city region level. This was undertaken by means of a workshop with both scientists, city representatives from several EU-countries, representatives of EU city networks and EU-experts. In this paper we introduce some important health related climate change issues, and discuss the current city policies of the participating cities. The workshop used a backcasting format to analyse the future relevance of a health perspective, and the main benefits and challenges this would bring to urban policy making. It was concluded that health issues have an important function as indicators of success for urban climate change policies, given the extent to which climate change policies contribute to public health and as such to quality of life. Simultaneously the health perspective may function as a policy integrator in that it can combine several related policy objectives, such as environmental policies, health policies, urban planning and economic development policies, in one framework for action. Furthermore, the participants to the workshop considered public health to be of strategic importance in organizing public support for climate change policies. One important conclusion of the workshop was the view that the connection of science and policy at the city level is inadequate, and that the integration of scientific knowledge on climate change related health effects and local policy practice is in need of more attention. In conclusion, the workshop was viewed as a constructive advance in the process of integration which hopefully will lead to ongoing cooperation. The workshop had the ambition to bring together a diversity of actor perspectives for exchange of knowledge and experiences, and joint understanding as a basis for future cooperation.

  3. Drosophila larvae: Thermal ecology in changing environments

    Temperature affects almost all aspects of life. Although much work has been done to assess the impact of temperature on organismal performance, relatively little is known about how organisms behaviorally regulate temperature, how these behaviors effect population fitness, or how changing climate may interact with these behaviors. I explore these questions with the model system Drosophila larvae. Larvae are small, with a low thermal mass and limited capacity for physiological thermoregulation. Mortality is generally high in larvae, with large potential impacts on population growth rate. Thus behavioral thermoregulation in larvae should be of critical selective importance. I present a review of the current knowledge of Drosophila thermal preference. I describe quantifiable thermoregulatory behaviors ( TMV and TW) unique to larvae. I show interspecific variation of these behaviors in Drosophila melanogaster and several close relatives, and intraspecific variation between populations collected from different environments. I also investigate these behaviors in two mutant lines, ssa and biz, to investigate the genetic basis of these behaviors. I show that larval thermoregulatory systems are independent of those of adults. Further these thermoregulatory behaviors differ between two sister species, D. yakuba and D. santomea. Although these two species readily hybridize in laboratory conditions, very few hybrids are observed in the field. The surprising result that hybrids of D. yakuba and D. santomea seem to inherit TMV from D. yakuba suggests a novel extrinsic isolation mechanism between the two species. I explore how fitness is the result of the interaction between genetics and the environment. I utilize Monte Carlo simulation to show how non-linear norms of reaction generate variation in populations even in the absence of behavior or epigenetic evolutionary mechanisms. Finally I investigate the global distribution of temperatures in which these organisms exist using

    Drilling fluids or "muds" are essential components of modern drilling operations. They provide integrity for the well bore, a medium for removal of formation cuttings, and lubrication and cooling of the drill bit and pipe. The modeling workshop described in this report was conducted September 14-18, 1981 in Gulf Breeze, Florida to consider potential impacts of discharged drilling muds and cuttings on the marine environment. The broad goals of the workshop were synthesis of information on fate and effects, identification of general relationships between drilling fluids and the marine environment, and identification of site-specific variables likely to determine impacts of drilling muds and cuttings in various marine sites. The workshop was structured around construction of a model simulating fate and effects of discharges from a single rig into open water areas of the Gulf of Mexico, and discussion of factors that might produce different fate and effects in enclosed areas such as bays and estuaries. The simulation model was composed of four connected submodels. A Discharge/Fate submodel dealt with the discharge characteristics of the rig and the subsequent fate of discharged material. Three effects submodels then calculated biological responses at distances away from the rig for the water column, soft bottom benthos (assuming the rig was located over a soft bottom environment), and hard bottom benthos (assuming the rig was located over a hard bottom environment). The model focused on direct linkages between the discharge and various organisms rather than on how the marine ecosystem itself is interconnected. Behavior of the simulation model indicated relatively localized effects of drilling muds and cuttings discharged from a single platform into open water areas. Water column fate and effects were dominated by rapid dilution. Effects from deposition of spent mud and cuttings were spatially limited with relatively rapid recovery, especially in soft bottom benthic

    The Building Strong Geoscience Departments project focuses on helping geoscience departments adapt and prosper in a changing and challenging environment. From 2005-2009, the project offered workshop programs on topics such as student recruitment, program assessment, preparing students for the workforce, and strengthening geoscience programs. Participants shared their departments' challenges and successes. Building on best practices and most promising strategies from these workshops and on workshop leaders' experiences, from 2009-2011 the project ran a visiting workshop program, bringing workshops to 18 individual departments. Two major strengths of the visiting workshop format are that it engages the entire department in the program, fostering a sense of shared ownership and vision, and that it focuses on each department's unique situation. Departments applied to have a visiting workshop, and the process was highly competitive. Selected departments chose from a list of topics developed through the prior workshops: curriculum and program design, program elements beyond the curriculum, recruiting students, preparing students for the workforce, and program assessment. Two of our workshop leaders worked with each department to customize and deliver the 1-2 day programs on campus. Each workshop incorporated exercises to facilitate active departmental discussions, presentations incorporating concrete examples drawn from the leaders' experience and from the collective experiences of the geoscience community, and action planning to scaffold implementation. All workshops also incorporated information on building departmental consensus and assessing departmental efforts. The Building Strong Geoscience Departments website complements the workshops with extensive examples from the geoscience community. Of the 201 participants in the visiting workshop program, 140 completed an end of workshop evaluation survey with an overall satisfaction rating of 8.8 out of a possible 10

    Cultural Heritage is the core of civilization and mankind and contributes substantially to quality of life. Its preservation for its historical value and aesthetics, for its conservation and transmission, must be one of the paramount preoccupations of each citizen and institution. It is therefore fundamental to guard against a major evolution of our planet that is increasing and harmful for all the materials: climate imbalance. The tangible Cultural Heritage, often in an urban environment, is threatened both by extreme climate events, relatively short but recurrent, and by slow, insidious and continuous ones, often in relationship with pollution. The main climate factor at global scale - a general increase of mean temperatures leading to sea level rise - will have direct and indirect consequences on Cultural Heritage. The other climate threats (rain, relative humidity, solar radiation, drought, wind, floods…) and pollution (by gases and particles) will have specific effects on materials of Cultural Heritage, both outdoors (façades of monuments, historical centres of cities, open-air statues, cultural landscapes…) and indoors (museums, libraries, reserves, collections…). Since the 1st International Workshop on « Climate Change and Cultural Heritage » held at the European University Centre for Cultural Heritage in Ravello in May 2009, three important events appeared: • The publication in 2014 of the 5th IPCC Assessment Report. For the first time the Cultural Heritage was cited in an IPCC Report. • The holding in 2015 in Paris of the COP21.

    The usefulness of cardiovascular measures as indicators of changes in cognitive workload has been addressed in several studies. In this paper the question is explored whether cardiovascular patterns in heart rate, blood pressure, baroreflex sensitivity and HRV that are found are consistent within and between two simulated working environments. Two studies, were performed, both with 21 participants: one in an ambulance dispatch simulation and one in a driving simulator. In the ambulance dispatcher task an initial strong increase in blood pressure is followed by a moderate on-going increase in blood pressure during the next hour of task performance. This pattern is accompanied by a strong increase in baroreflex sensitivity while heart rate decreases. In the driving simulator study, blood pressure initially increases but decreases almost to baseline level in the next hour. This pattern is accompanied by a decrease in baroreflex sensitivity, while heart rate decreases. Results of both studies are interpreted in terms of autonomic control (related to both sympathetic and para-sympathetic effects), using a simplified simulation of a baroreflex regulation model. Interpretation of the results leads to the conclusion that the cardiovascular response patterns in both tasks are a combination of an initial defensive reaction, in combination with compensatory blood pressure control. The level of compensatory blood pressure control, however, is quite different for the two tasks. This helps to understand the differences in response patterns between the two studies in this paper and may be helpful as well for understanding differences in cardiovascular response patterns in general. A substantial part of the effects observed during task performance are regulatory effects and are not always directly related to workload manipulations. Making this distinction may also contribute to the understanding of differences in cardiovascular response patterns during cognitive workload. PMID

    Problem-based learning (PBL) has over the years become a learning strategy established for teaching students in medicine. In order to use PBL as a teaching tool, faculty must be familiar with PBL and comfortable with the role transition from 'teacher' to 'facilitator'. This transition is critical for the success of PBL. This article describes the faculty development process undertaken in Pakistan at the onset of introduction of PBL in the curriculum. At the Foundation University Medical College (FUMC), we initiated a faculty development program in PBL. The program consisted of two-day, hands-on facilitator training workshops conducted five times over the year and led by in-house faculty. A total of 180 faculty members completed these workshops. The workshops consisted of interactive sessions on the philosophy of PBL, small group dynamics, the role of the facilitator, an introduction to case design, wrap-up PBL sessions and assessment in PBL. Participants were provided with pre-workshop reading material in the form of 'PBL Handbooks', which contained details of the PBL process and specific responsibilities of the facilitator. Participants were also given a chance to experience the role of the facilitator by facilitating the faculty-learner group through a PBL session and receiving feedback. A retrospective pre-post survey was conducted to gauge changes in participants' perceptions of PBL. The faculty reported a significant increase in their regard for PBL as an instructional paradigm (p=<0.001). They also generally became more interested in empowering students with self-directed learning using PBL as a teaching tool and showed a greater desire to be facilitators (p=<0.001). This evaluation reveals that facilitator training workshops can help not just to improve the facilitation skills of participants but also to stimulate interest amongst faculty to use PBL in the curriculum. Such workshops can be run in Pakistan at minimal cost: the only cost we incurred was for

    2014-06-30

    Seagrass meadows are valuable ecosystem service providers that are now being lost globally at an unprecedented rate, with water quality and other localised stressors putting their future viability in doubt. It is therefore critical that we learn more about the interactions between seagrass meadows and future environmental change in the anthropocene. This needs to be with particular reference to the consequences of poor water quality on ecosystem resilience and the effects of change on trophic interactions within the food web. Understanding and predicting the response of seagrass meadows to future environmental change requires an understanding of the natural long-term drivers of change and how these are currently influenced by anthropogenic stress. Conservation management of coastal and marine ecosystems now and in the future requires increased knowledge of how seagrass meadows respond to environmental change, and how they can be managed to be resilient to these changes. Finding solutions to such issues also requires recognising people as part of the social-ecological system. This special issue aims to further enhance this knowledge by bringing together global expertise across this field. The special issues considers issues such as ecosystem service delivery of seagrass meadows, the drivers of long-term seagrass change and the socio-economic consequences of environmental change to seagrass.

    Estimating abundance of Antarctic minke whales is central to the International Whaling Commission's conservation and management work and understanding impacts of climate change on polar marine ecosystems. Detecting abundance trends is problematic, in part because minke whales are frequently sighted within Antarctic sea ice where navigational safety concerns prevent ships from surveying. Using icebreaker-supported helicopters, we conducted aerial surveys across a gradient of ice conditions to estimate minke whale density in the Weddell Sea. The surveys revealed substantial numbers of whales inside the sea ice. The Antarctic summer sea ice is undergoing rapid regional change in annual extent, distribution, and length of ice-covered season. These trends, along with substantial interannual variability in ice conditions, affect the proportion of whales available to be counted by traditional shipboard surveys. The strong association between whales and the dynamic, changing sea ice requires reexamination of the power to detect trends in whale abundance or predict ecosystem responses to climate change.

    We study the adaptive behavior of a computational ecosystem in the presence of time-periodic resource utilities as seen, for example in the day-night load variations of computer use and in the price fluctuations of seasonal products. We do so within the context of the Huberman-Hogg model of such systems. The dynamics is studied for the cases of competitive and cooperative payoff functions with time-modulated resource utilities, and the system’s adaptability is measured by tracking its performance in response to a time-varying environment,

    Model projections indicate that climate change may dramatically restructure phytoplankton communities, with cascading consequences for marine food webs. It is currently not known whether evolutionary change is likely to be able to keep pace with the rate of climate change. For simplicity, and in the absence of evidence to the contrary, most model projections assume species have fixed environmental preferences and will not adapt to changing environmental conditions on the century scale. Using 15 y of observations from Station CARIACO (Carbon Retention in a Colored Ocean), we show that most of the dominant species from a marine phytoplankton community were able to adapt their realized niches to track average increases in water temperature and irradiance, but the majority of species exhibited a fixed niche for nitrate. We do not know the extent of this adaptive capacity, so we cannot conclude that phytoplankton will be able to adapt to the changes anticipated over the next century, but community ecosystem models can no longer assume that phytoplankton cannot adapt.

    This study presents the results of an evaluation of a participatory hydrologic modeling workshop in Hermosillo, Sonora, Mexico. This is a region experiencing serious, ongoing water quantity and quality problems. Our goals were to assess the value of a set of hydrologic models for participants and to learn whether providing them with new water-related information changed their perceptions. The hydrologic model focused on water quantity issues, while workshop presentations also incorporated information about water quality problems. In addition to asking a series of questions about the value and quality of the model and workshop, we assessed changes in participant perceptions of water-related problems, causes, impacts, and solutions before and after the workshop. Forty-six Mexican water resource decision makers attended the workshop and returned surveys. We report on our findings that some participant perceptions changed significantly before and after the workshop. In addition, we present the results from our regression modeling of beliefs about the value of hydrologic modeling for water resource-related decision making. The results have important implications for other participatory hydrologic modeling efforts and demonstrate how a careful presentation of technical decision making tools can prove valuable for decision makers in a less developed region where available data may be sparse.

    Communication plays a fundamental role in science and engineering disciplines. However, many higher education programs provide little, if any, technical communication coursework. Without strong communication skills scientists and engineers have less opportunity to publish, obtain competitive research funds, or grow their careers. This article describes the role of scientific communication training as an innovative staff development program in a learning-intensive workplace – a national scientific research and development laboratory. The findings show that involvement in the workshop has increased overall participating staff annual publications by an average of 61 percent compared to their pre-workshop publishing performance as well as confidence level in their ability to write and publish peer-reviewed literature. Secondary benefits include improved information literacy skills and the development of informal communities of practice. This work provides insight into adult education in the workplace.

    When exposed to stressful conditions, plants accumulate an array of metabolites, particularly amino acids. Amino acids have traditionally been considered as precursors to and constituents of proteins, and play an important role in plant metabolism and development. A large body of data suggests a positive correlation between proline accumulation and plant stress. Proline, an amino acid, plays a highly beneficial role in plants exposed to various stress conditions. Besides acting as an excellent osmolyte, proline plays three major roles during stress, i.e., as a metal chelator, an antioxidative defense molecule and a signaling molecule. Review of the literature indicates that a stressful environment results in an overproduction of proline in plants which in turn imparts stress tolerance by maintaining cell turgor or osmotic balance; stabilizing membranes thereby preventing electrolyte leakage; and bringing concentrations of reactive oxygen species (ROS) within normal ranges, thus preventing oxidative burst in plants. Reports indicate enhanced stress tolerance when proline is supplied exogenously at low concentrations. However, some reports indicate toxic effects of proline when supplied exogenously at higher concentrations. In this article, we review and discuss the effects of exogenous proline on plants exposed to various abiotic stresses. Numerous examples of successful application of exogenous proline to improve stress tolerance are presented. The roles played by exogenous proline under varying environments have been critically examined and reviewed. PMID:22951402

  11. Using workshops to develop theories of change in five low and middle income countries: lessons from the programme for improving mental health care (PRIME)

    PubMed Central

    2014-01-01

    Background The Theory of Change (ToC) approach has been used to develop and evaluate complex health initiatives in a participatory way in high income countries. Little is known about its use to develop mental health care plans in low and middle income countries where mental health services remain inadequate. Aims ToC workshops were held as part of formative phase of the Programme for Improving Mental Health Care (PRIME) in order 1) to develop a structured logical and evidence-based ToC map as a basis for a mental health care plan in each district; (2) to contextualise the plans; and (3) to obtain stakeholder buy-in in Ethiopia, India, Nepal, South Africa and Uganda. This study describes the structure and facilitator’s experiences of ToC workshops. Methods The facilitators of the ToC workshops were interviewed and the interviews were recorded, transcribed and analysed together with process documentation from the workshops using a framework analysis approach. Results Thirteen workshops were held in the five PRIME countries at different levels of the health system. The ToC workshops achieved their stated goals with the contributions of different stakeholders. District health planners, mental health specialists, and researchers contributed the most to the development of the ToC while service providers provided detailed contextual information. Buy-in was achieved from all stakeholders but valued more from those in control of resources. Conclusions ToC workshops are a useful approach for developing ToCs as a basis for mental health care plans because they facilitate logical, evidence based and contextualised plans, while promoting stakeholder buy in. Because of the existing hierarchies within some health systems, strategies such as limiting the types of participants and stratifying the workshops can be used to ensure productive workshops.

    Today s HPC centers user environments can be very complex. Centers often contain multiple large complicated computational systems each with their own user environment. Changes to a system s environment can be very impactful; however, a center s user environment is, in one-way or another, frequently changing. Because of this, it is vital for centers to notify users of change. For users, untracked changes can be costly, resulting in unnecessary debug time as well as wasting valuable compute allocations and research time. Communicating frequent change to diverse user communities is a common and ongoing task for HPC centers. This paper will cover the OLCF s current processes and methods used to communicate change to users of the center s large Cray systems and supporting resources. The paper will share lessons learned and goals as well as practices, tools, and methods used to continually improve and reach members of the OLCF user community.

    Competitive pressures in the electric utility industry today demand an unprecedented focus on improving efficiency and cost effectiveness. Work processes and practices that, in some cases, have been in place for years are now being examined and changed in attempts to achieve better results. When such changes are made in nuclear plant work processes, however, the resulting impact on nuclear risk is a potential concern. Two types of risk must be considered: (a) the direct impact of new processes that might inadvertently introduce new safety concerns and (b) the indirect effects on safety due to worker morale and motivation. Work processes and practices at the GPU nuclear stations at Oyster Creek and Three Mile Island (TMI) were developed and put in place in the period following the TMI-2 accident. During this period, great emphasis was placed on installing work processes that attempted to avoid errors through a multiplicity of checks and overchecks. During 1991, GPUN senior management initiated a substantial effort to achieve major improvements in efficiency and effectiveness of key work processes, while maintaining and even enhancing nuclear safety.

    Interest and concern for the Earth`s changing atmosphere has increased dramatically in recent years. Future increases in atmospheric CO{sub 2} concentration will directly affect physiological processes and growth rates of plants. Indirect climatic effects such as global warming, changing precipitation patterns, increasing cloud cover, and frequency of weather extremes may have a greater impact than the direct CO{sub 2}-induced changes on plant processes. The authors conducted several experiments in naturally-lit, temperature-, and CO{sub 2}-controlled chambers and measured both upland (Gossypium hirsutum L.) and pima (G. barbadense L.) cotton crop responses to the direct and interactive effects of temperature, CO{sub 2}, and water deficits. Absolute differences in photosynthetic rates at different CO{sub 2} concentrations became progressively greater with time as plants entered reproductive phases of growth. The photosynthetic response to CO{sub 2} increased up to {approx} 700 to 900 {micro}mol mol{sup {minus}1} CO{sub 2}, and the authors did not detect any feedback inhibition of photosynthesis in cotton over time. The relative photosynthetic response of plants growth at 700 {micro}mol mol{sup {minus}1} CO{sub 2} compared with plants grown at 350 {micro}mol mol{sup {minus}1} CO{sub 2} was at a maximum of 1.5 at 30 C, but decreased to near 1.0 at 24 and 38 C. This relative response was very similar to responses of growth to CO{sub 2} and temperature and thus photosynthetic responses may be related to sink size. Plants grown in high CO{sub 2} atmospheres produced more photosynthesis under optimum and in water stress conditions than plants grown in ambient CO{sub 2} atmospheres. High CO{sub 2} grown plants transpired less at high plant leaf water potentials than low CO{sub 2} grown plants, but transpiration rates were not different when leaf water potentials decreased below {minus} 2.0 MPa. 37 refs., 21 figs.

    Aspen communities are biologically rich and ecologically valuable, yet they face myriad threats, including changing climate, altered fire regimes, and excessive browsing by domestic and wild ungulates. Recognizing the different types of aspen communities that occur in the Great Basin, and being able to distinguish between seral and stable aspen stands, can help managers better identify restoration needs and objectives. Identifying key threats to aspen regeneration and persistence in a given stand or landscape is important to designing restoration plans, and to selecting appropriate treatment types. Although some aspen stands will need intensive treatment (e.g., use of fire) to persist or remain healthy, other stands may only require the modification of current management practices (e.g., reducing livestock browsing) or may not require any action at all (e.g., self-replacing stable aspen communities).

    Astrobiology is defined in the 1996 NASA Strategic Plan as 'The study of the living universe.' At NASA's Ames Research Center, this endeavor encompasses the use of space to understand life's origin, evolution, and destiny in the universe. Life's origin refers to understanding the origin of life in the context of the origin and diversity of planetary systems. Life's evolution refers to understanding how living systems have adapted to Earth's changing environment, to the all-pervasive force of gravity, and how they may adapt to environments beyond Earth. Life's destiny refers to making long-term human presence in space a reality, and laying the foundation for understanding and managing changes in Earth's environment. The first Astrobiology Workshop brought together a diverse group of researchers to discuss the following general questions: Where and how are other habitable worlds formed? How does life originate? How have the Earth and its biosphere influenced each other over time? Can terrestrial life be sustained beyond our planet? How can we expand the human presence to Mars? The objectives of the Workshop included: discussing the scope of astrobiology, strengthening existing efforts for the study of life in the universe, identifying new cross-disciplinary programs with the greatest potential for scientific return, and suggesting steps needed to bring this program to reality. Ames has been assigned the lead role for astrobiology by NASA in recognition of its strong history of leadership in multidisciplinary research in the space, Earth, and life sciences and its pioneering work in studies of the living universe. This initial science workshop was established to lay the foundation for what is to become a national effort in astrobiology, with anticipated participation by the university community, other NASA centers, and other agencies. This workshop (the first meeting of its kind ever held) involved life, Earth, and space scientists in a truly interdisciplinary sharing

    A decade ago, the U.S. chemical industry was in decline. Of the more than 40 chemical manufacturing plants being built worldwide in the mid-2000s with more than $1 billion in capitalization, none were under construction in the United States. Today, as a result of abundant domestic supplies of affordable natural gas and natural gas liquids resulting from the dramatic rise in shale gas production, the U.S. chemical industry has gone from the world’s highest-cost producer in 2005 to among the lowest-cost producers today. The low cost and increased supply of natural gas and natural gas liquids provides an opportunity to discover and develop new catalysts and processes to enable the direct conversion of natural gas and natural gas liquids into value-added chemicals with a lower carbon footprint. The economic implications of developing advanced technologies to utilize and process natural gas and natural gas liquids for chemical production could be significant, as commodity, intermediate, and fine chemicals represent a higher-economic-value use of shale gas compared with its use as a fuel. To better understand the opportunities for catalysis research in an era of shifting feedstocks for chemical production and to identify the gaps in the current research portfolio, the National Academies of Sciences, Engineering, and Medicine conducted an interactive, multidisciplinary workshop in March 2016. The goal of this workshop was to identify advances in catalysis that can enable the United States to fully realize the potential of the shale gas revolution for the U.S. chemical industry and, as a result, to help target the efforts of U.S. researchers and funding agencies on those areas of science and technology development that are most critical to achieving these advances. This publication summarizes the presentations and discussions from the workshop.

  3. Essays in energy, environment and technological change

    NASA Astrophysics Data System (ADS)

    Zhou, Yichen Christy

    This dissertation studies technological change in the context of energy and environmental economics. Technology plays a key role in reducing greenhouse gas emissions from the transportation sector. Chapter 1 estimates a structural model of the car industry that allows for endogenous product characteristics to investigate how gasoline taxes, R&D subsidies and competition affect fuel efficiency and vehicle prices in the medium-run, both through car-makers' decisions to adopt technologies and through their investments in knowledge capital. I use technology adoption and automotive patents data for 1986-2006 to estimate this model. I show that 92% of fuel efficiency improvements between 1986 and 2006 were driven by technology adoption, while the role of knowledge capital is largely to reduce the marginal production costs of fuel-efficient cars. A counterfactual predicts that an additional 1/gallon gasoline tax in 2006 would have increased the technology adoption rate, and raised average fuel efficiency by 0.47 miles/gallon, twice the annual fuel efficiency improvement in 2003-2006. An R&D subsidy that would reduce the marginal cost of knowledge capital by 25% in 2006 would have raised investment in knowledge capital. This subsidy would have raised fuel efficiency only by 0.06 miles/gallon in 2006, but would have increased variable profits by 2.3 billion over all firms that year. Passenger vehicle fuel economy standards in the United States will require substantial improvements in new vehicle fuel economy over the next decade. Economic theory suggests that vehicle manufacturers adopt greater fuel-saving technologies for vehicles with larger market size. Chapter 2 documents a strong connection between market size, measured by sales, and technology adoption. Using variation consumer demographics and purchasing pattern to account for the endogeneity of market size, we find that a 10 percent increase in market size raises vehicle fuel efficiency by 0.3 percent, as compared

    The Asian Network on Climate Science and Technology (www.ancst.org), in collaboration with Tsinghua University, held a conference on environmental and climate science, air pollution, urban planning and transportation in July 2015, with over 40 Asian experts participating and presentation. This was followed by a meeting with local government and community experts on the practical conclusions of the conference. Of the papers presented at the conference a selection are included in this special issue of Journal of Environmental Science, which also reflects the conclusions of the Paris Climate meeting in Dec 2015, when the major nations of the world agreed about the compelling need to reduce the upward trend of adverse impacts associated with global climate change. Now is the time for urban areas to work out the serious consequences for their populations, but also how they should work together to take action to reduce global warming to benefit their own communities and also the whole planet!

    Development of satisfactory techniques for detecting change in coastal zone environments is required before operational monitoring procedures can be established. In an effort to meet this need a study was directed toward developing and evaluating different types of change detection techniques, based upon computer aided analysis of LANDSAT multispectral scanner (MSS) data, to monitor these environments. The Matagorda Bay estuarine system along the Texas coast was selected as the study area. Four change detection techniques were designed and implemented for evaluation: (1) post classification comparison change detection, (2) delta data change detection, (3) spectral/temporal change classification, and (4) layered spectral/temporal change classification. Each of the four techniques was used to analyze a LANDSAT MSS temporal data set to detect areas of change of the Matagorda Bay region.

    Autoimmune diseases include 80 or more complex disorders characterized by self-reactive, pathologic immune responses in which genetic susceptibility is largely insufficient to determine disease onset. In September 2010, the National Institute of Environmental Health Sciences (NIEHS) organized an expert panel workshop to evaluate the role of environmental factors in autoimmune diseases, and the state of the science regarding relevant mechanisms, animal models, and human studies. The objective of the workshop was to analyze the existing data to identify conclusions that could be drawn regarding environmental exposures and autoimmunity and to identify critical knowledge gaps and areas of uncertainty for future study. This consensus document summarizes key findings from published workshop monographs on areas in which “confident” and “likely” assessments were made, with recommendations for further research. Transcribed notes and slides were reviewed to synthesize an overview on exposure assessment and questions addressed by interdisciplinary panels. Critical advances in the field of autoimmune disease research have been made in the past decade. Collaborative translational and interdisciplinary research is needed to elucidate the role of environmental factors in autoimmune diseases. A focus on exposure assessment methodology is needed to improve the effectiveness of human studies, and more experimental studies are needed to focus on causal mechanisms underlying observed associations of environmental factors with autoimmune disease in humans.

  19. Vegetation change in dryland environments: understanding changes in fluvial fluxes via changes in hydrological connectivity

    NASA Astrophysics Data System (ADS)

    Puttock, A.; Brazier, R. E.; Dungait, J. A. J.; Bol, R.; Macleod, C. J. A.

    Dryland environments are estimated to cover around 40% of the global land surface (Okin et al, 2009) and are home to approximately 2.5 billion people (Reynolds et al. 2007). Many of these areas have recently experienced extensive land degradation. One such area and the focus of this project is the semi-arid US Southwest, where degradation over the past 150 years has been characterised by the invasion of woody vegetation into grasslands. The transition from grass to woody vegetation results in a change in ecosystem structure and function (Turnbull et al, 2008). Structural change is typically characterised by an increased heterogeneity of soil and vegetation resources, associated with reduced vegetation coverage. Functional change is characterised by an increased vulnerability to soil erosion and the potential loss of key nutrients to adjacent fluvial systems. Such loss of resources may impact heavily upon the amount of carbon that is sequestered by these environments and the amount of carbon that is lost as the land becomes more degraded. Therefore, understanding these vegetation transitions is significant for sustainable land use and global biogeochemical cycling. Connectivity is a key concept in understanding the hydrological response to this vegetation change, with reduced vegetation coverage in woody environments being associated with longer and more connected overland flow pathways. This increase in hydrological connectivity results in an accentuated rainfall-runoff response and increased fluvial fluxes of eroded sediment and associated soil organic carbon and other nutrients. This project uses an ecohydrological approach, characterising ecological structure and monitoring natural rainfall-runoff events over bounded plots with different vegetation covering the transitions from C4 pure-grass (Bouteloua eriopoda) to C3 creosote (Larrea tridentate) shrubland and C3 piñon-juniper (Pinus edulis-Juniperus monosperma) mixed stand woodland.

  10. Biodiversity inhibits species' evolutionary responses to changing environments.

    PubMed

    de Mazancourt, C; Johnson, E; Barraclough, T G

    2008-04-01

    Despite growing interplay between ecological and evolutionary studies, the question of how biodiversity influences evolutionary dynamics within species remains understudied. Here, using a classical model of phenotypic evolution in species occupying a patchy environment, but introducing global change affecting patch conditions, we show that biodiversity can inhibit species' evolution during global change. The presence of several species increases the chance that one or more species are pre-adapted to new conditions, which restricts the ecological opportunity for evolutionary responses in all the species. Consequently, environmental change tends to select for changes in species abundances rather than for changing phenotypes within each species. The buffering effects of species diversity that we describe might be one important but neglected explanation for widely observed niche conservatism in natural systems. Furthermore, the results show that attempts to understand biotic responses to environmental change need to consider both ecological and evolutionary processes in a realistically diverse setting.

    Students' perceptions of their learning environment influence both how they learn and the quality of their learning outcomes. The clinical component of undergraduate medical courses takes place in an environment designed for clinical service and not teaching. Tension results when these two activities compete for resources. An impending increase in medical student numbers led us to assess the learning environment with a view to planning for the future. An open ended question 'If you could change three things about medical school, what would they be?' was added to the Dundee Ready Educational Environment Measure (DREEM). This was used to assess the learning environment of students in years 4 and 5. Allowing students to actively voice their views about changes in the curriculum was considered a useful extension to the DREEM questionnaire. The findings indicated commonalities over the two years of clinical teaching. The areas of commonality included the need for: more clinical exposure early in the curriculum; fewer lectures; greater consistency in terms of assessment; and more constructive relationships. Fourth-year students tended to voice more concerns around resourcing, and sought more clarification about roles and learning outcomes. There is a need to address concerns raised by students in the areas of curricula, assessments and access to earlier clinical training. Concerns that can be addressed are increasing resource access, implementation of clearer objectives, consistency of teaching and assessments across sites, more formative assessments, and engaging feedback. Students would also benefit from substantive mentoring and role-modelling. © Blackwell Publishing Ltd 2011.

    The Second US - Japan Workshop on Global Change: Environmental Response Technologies for Global Change was hosted by the Program on Resources at the East-West Center, in Honolulu, Hawaii on February 1--3, 1993, on behalf of the United States Committee on Earth and Environmental Sciences (CEES) of the Federal Coordinating Council for Science, Engineering, and Technology (FCCSET). This workshop brought together over fifty leading scientists from the two countries to review existing technologies and to identify needed research on the development of new technologies for mitigation and adaptation of global change. The Workshop was organized around three areas of research: (1) capture, fixation/utilization, and disposal of CO{sub 2} (e.g. CO{sub 2}, separation and capture technologies, ocean and land disposal of CO{sub 2}; (2) energy production and conservation technologies to reduce greenhouse gas emissions (e.g. combustion efficiency, non-carbon based energy technologies, energy conservation technologies); and (3) adaptation technologies and practices related to global climate change (e.g., adaptation responses of crops to climate change, adapting urban infrastructure for climate change). Priorities for joint research in each of these areas were discussed. Selected papers have been processed separately for inclusion in the Energy Science and Technology Database.

  18. Geometric change detection in urban environments using images.

    PubMed

    2015-11-01

    We propose a method to detect changes in the geometry of a city using panoramic images captured by a car driving around the city. The proposed method can be used to significantly optimize the process of updating the 3D model of an urban environment that is changing over time, by restricting this process to only those areas where changes are detected. With this application in mind, we designed our algorithm to specifically detect only structural changes in the environment, ignoring any changes in its appearance, and ignoring also all the changes which are not relevant for update purposes such as cars, people etc. The approach also accounts for the challenges involved in a large scale application of change detection, such as inaccuracies in the input geometry, errors in the geo-location data of the images as well as the limited amount of information due to sparse imagery. We evaluated our approach on a small scale setup using high resolution, densely captured images and a large scale setup covering an entire city using instead the more realistic scenario of low resolution, sparsely captured images. A quantitative evaluation was also conducted for the large scale setup consisting of 14,000 images.

    While aquatic environments have long been thought to be more moderate environments than their terrestrial cousins, environmental data demonstrate that for some systems this is not so. Numerous important environmental parameters can fluctuate dramatically, notably dissolved oxygen, turbidity and temperature. The roles of dissolved oxygen and turbidity on predator-prey interactions have been discussed in detail elsewhere within this issue and will be considered only briefly here. Here, we will focus primarily on the role of temperature and its potential impact upon predator-prey interactions. Two key properties are of particular note. For temperate aquatic ecosystems, all piscine and invertebrate piscivores and their prey are ectothermic. They will therefore be subject to energetic demands that are significantly affected by environmental temperature. Furthermore, the physical properties of water, particularly its high thermal conductivity, mean that thermal microenvironments will not exist so that fine-scale habitat movements will not be an option for dealing with changing water temperature in lentic environments. Unfortunately, there has been little experimental analysis of the role of temperature on such predator-prey interactions, so we will instead focus on theoretical work, indicating that potential implications associated with thermal change are unlikely to be straightforward and may present a greater threat to predators than to their prey. Specifically, we demonstrate that changes in the thermal environment can result in a net benefit to cold-adapted species through the mechanism of predator-prey interactions.

    This paper examines U.S. export control, with particular emphasis on technology transfer as it affects our relationship with Japan. It describes the evolution of export control in the United States, including the Bucy Report, the impact of Afghanistan, and policy changes regarding the People's Republic of China. U.S. control mechanisms for critical technology currently in place are described; these include the Export Administration Regulations, the International Traffic in Arms Regulations (ITAR), and the Militarily Critical Technologies List (MCTL). The evolution of Japan's technology base and export control mechanisms are discussed, as well as its military capabilities. Japan and the United States have had different philosophies regarding export control, with the United States more likely to use controls as part of its foreign policy. However, U.S. export control policy is increasingly seen as having an important economic security aspect in addition to its national security objectives. Changes in Eastern Europe and the Soviet Union have placed the issue of export control in a new perspective. Therefore, the paper also examines in some detail the major developments in the European community which will affect the future technology environment and its relationship to national security. This paper was originally presented at a workshop of the Japan-U.S. Joint Study Group on Trade, Finance and Technology in East-West Economic Relations. A primary purpose of the paper was to enhance mutual understanding between the United States and Japan, and to facilitate the resolution of differences in the technology security arena.

    Emotional responses to biologically significant events are essential for human survival. Do human emotions lawfully track changes in the acoustic environment? Here we report that changes in acoustic attributes that are well known to interact with human emotions in speech and music also trigger systematic emotional responses when they occur in environmental sounds, including sounds of human actions, animal calls, machinery, or natural phenomena, such as wind and rain. Three changes in acoustic attributes known to signal emotional states in speech and music were imposed upon 24 environmental sounds. Evaluations of stimuli indicated that human emotions track such changes in environmental sounds just as they do for speech and music. Such changes not only influenced evaluations of the sounds themselves, they also affected the way accompanying facial expressions were interpreted emotionally. The findings illustrate that human emotions are highly attuned to changes in the acoustic environment, and reignite a discussion of Charles Darwin’s hypothesis that speech and music originated from a common emotional signal system based on the imitation and modification of environmental sounds.

  7. Testing take-the-best in new and changing environments.

    Take-the-best is a decision-making strategy that chooses between alternatives, by searching the cues representing the alternatives in order of cue validity, and choosing the alternative with the first discriminating cue. Theoretical support for take-the-best comes from the "fast and frugal" approach to modeling cognition, which assumes decision-making strategies need to be fast to cope with a competitive world, and be simple to be robust to uncertainty and environmental change. We contribute to the empirical evaluation of take-the-best in two ways. First, we generate four new environments-involving bridge lengths, hamburger prices, theme park attendances, and US university rankings-supplementing the relatively limited number of naturally cue-based environments previously considered. We find that take-the-best is as accurate as rival decision strategies that use all of the available cues. Secondly, we develop 19 new data sets characterizing the change in cities and their populations in four countries. We find that take-the-best maintains its accuracy and limited search as the environments change, even if cue validities learned in one environment are used to make decisions in another. Once again, we find that take-the-best is as accurate as rival strategies that use all of the cues. We conclude that these new evaluations support the theoretical claims of the accuracy, frugality, and robustness for take-the-best, and that the new data sets provide a valuable resource for the more general study of the relationship between effective decision-making strategies and the environments in which they operate.

  8. Plasticity-Mediated Persistence in New and Changing Environments

    Baldwin's synthesis of the Organicist position, first published in 1896 and elaborated in 1902, sought to rescue environmentally induced phenotypes from disrepute by showing their Darwinian significance. Of particular interest to Baldwin was plasticity's mediating role during environmental change or colonization—plastic individuals were more likely to successfully survive and reproduce in new environments than were nonplastic individuals. Once a population of plastic individuals had become established, plasticity could further mediate the future course of evolution. The evidence for plasticity-mediated persistence (PMP) is reviewed here with a particular focus on evolutionary rescue experiments, studies on invasive success, and the role of learning in survival. Many PMP studies are methodologically limited, showing that preexistent plasticity has utility in new environments (soft PMP) rather than directly demonstrating that plasticity is responsible for persistence (hard PMP). An ideal PMP study would be able to demonstrate that (1) plasticity preexisted environmental change, (2) plasticity was fortuitously beneficial in the new environment, (3) plasticity was responsible for individual persistence in the new environment, and (4) plasticity was responsible for population persistence in succeeding generations. Although PMP is not ubiquitous, Baldwin's hypotheses have been largely vindicated in theoretical and empirical studies, but much work remains. PMID:25386380

  9. Changing the Environment Based on Empowerment as Intrinsic Motivation

    2014-05-01

    One aspect of intelligence is the ability to restructure your own environment so that the world you live in becomes more beneficial to you. In this paper we investigate how the information-theoretic measure of agent empowerment can provide a task-independent, intrinsic motivation to restructure the world. We show how changes in embodiment and in the environment change the resulting behaviour of the agent and the artefacts left in the world. For this purpose, we introduce an approximation of the established empowerment formalism based on sparse sampling, which is simpler and significantly faster to compute for deterministic dynamics. Sparse sampling also introduces a degree of randomness into the decision making process, which turns out to beneficial for some cases. We then utilize the measure to generate agent behaviour for different agent embodiments in a Minecraft-inspired three dimensional block world. The paradigmatic results demonstrate that empowerment can be used as a suitable generic intrinsic motivation to not only generate actions in given static environments, as shown in the past, but also to modify existing environmental conditions. In doing so, the emerging strategies to modify an agent's environment turn out to be meaningful to the specific agent capabilities, i.e., de facto to its embodiment.

    We consider an agent that must choose repeatedly among several actions. Each action has a certain probability of giving the agent an energy reward, and costs may be associated with switching between actions. The agent does not know which action has the highest reward probability, and the probabilities change randomly over time. We study two learning rules that have been widely used to model decision-making processes in animals-one deterministic and the other stochastic. In particular, we examine the influence of the rules' 'learning rate' on the agent's energy gain. We compare the performance of each rule with the best performance attainable when the agent has either full knowledge or no knowledge of the environment. Over relatively short periods of time, both rules are successful in enabling agents to exploit their environment. Moreover, under a range of effective learning rates, both rules are equivalent, and can be expressed by a third rule that requires the agent to select the action for which the current run of unsuccessful trials is shortest. However, the performance of both rules is relatively poor over longer periods of time, and under most circumstances no better than the performance an agent could achieve without knowledge of the environment. We propose a simple extension to the original rules that enables agents to learn about and effectively exploit a changing environment for an unlimited period of time.

    Influence of cosmic rays variations on the Sun-Earth Environment has been observed before the changes in the atmospheric temperature, outbreak of influenza, cyclone, earthquake and tsunami. It has been recorded by Sun Observatory Heleospheric Observatory (SOHO) satellite data. Before the earthquake and tsunami the planetary indices (Kp) and Electron flux (E-flux) shows sudden changes followed by the atmospheric perturbations including very high temperature rise to sudden fall resulting snowfall in high altitude and rainfall in tropical areas. The active fault zones shows sudden faulting after the sudden drop in cosmic ray intensity and rise in Kp and E-flux. Besides the geo-environment the extraterrestrial influence on outbreak of H1N1 influenza has also been recorded based on the Mexico Cosmic ray data and its correlation with SOHO records. Distant stars have the potential to influence the heliophysical parameters by showering cosmic rays.

    An important question stated in the presented paper is: Could rotifers be the indicators of climate change in the Antarctic environments? Rotifers are one of the most important components of the invertebrate fauna of the Antarctic freshwater and terrestrial ecosystems. However, investigations of their distribution, diversity and an ecological role in the environment have been widely neglected, mainly due to the methodological and taxonomical difficulties. During the investigations 176 species of rotifers were found, including the endemic and cosmopolitan species. Their existence is directly proportional to microvariations of humidity factor. Scientists still have poor knowledge about the occurrence of rotifer species in recently studied habitats e.g. cryoconite holes, nunataks or soil. Probably rotifers could be the indicators of climate change in the Antarctic freshwater and terrestrial ecosystems but more investigations and monitoring studies are needed

    The predicted climate warming has raised many questions and concerns about its impacts on the environment and society. As a respond to the need of holistic studies comprising both of these areas, The Academy of Finland launched The Finnish Research Programme on Climate Change (FICCA 2011-2014) in spring 2010 with the main aim to focus on the interaction between the environment and society. Ultimately 11 national consortium projects were funded (total budget 12 million EUR). Here we shortly present the main objectives of the largest consortium project "Climate change on arctic environment, ecosystem services and society" (CLICHE). The CLICHE consortium comprises eight interrelated work packages (treeline, diversity, peatlands, snow, lakes, fish, tourism, and traditional livelihoods), each led by a prominent research group and a team leader. The research consortium has three main overall objectives: 1) Investigate, map and model the past, present and future climate change-induced changes in central ecosystems of the European Arctic with unprecedented precision 2) Deepen our understanding of the basic principles of ecosystem and social resilience and dynamics; identify key taxa, structures or processes that clearly indicate impending or realised global change through their loss, occurrence or behaviour, using analogues from the past (e.g. Holocene Thermal Maximum, Medieval Warm Period), experiments, observations and models 3) Develop adaptation and mitigation strategies to minimize the adverse effects of climate change on local communities, traditional livelihoods, fisheries, and tourism industry, and promote sustainable development of local community structures and enhance the quality of life of local human populations. As the project has started only recently no final results are available yet. However, the fieldwork as well as the co-operation between the research teams has thus far been very successful. Thus, the expectations for the final outcome of the project

    Natural sounds such as wind or rain, are characterized by the statistical occurrence of their constituents. Despite their complexity, listeners readily detect changes in these contexts. We here address the neural basis of statistical decision-making using a combination of psychophysics, EEG and modelling. In a texture-based, change-detection paradigm, human performance and reaction times improved with longer pre-change exposure, consistent with improved estimation of baseline statistics. Change-locked and decision-related EEG responses were found in a centro-parietal scalp location, whose slope depended on change size, consistent with sensory evidence accumulation. The potential's amplitude scaled with the duration of pre-change exposure, suggesting a time-dependent decision threshold. Auditory cortex-related potentials showed no response to the change. A dual timescale, statistical estimation model accounted for subjects' performance. Furthermore, a decision-augmented auditory cortex model accounted for performance and reaction times, suggesting that the primary cortical representation requires little post-processing to enable change-detection in complex acoustic environments.

    We describe gene-environment processes that may help account for individual differences in successful aging. Our emphasis is on successful aging in the cognitive domain, wherein individuals come to use a variety of strategies to cope with changes in cognitive capacities. We focus on the role of executive control in particular and define gene-environment correlation and nonshared environmental mechanisms. The quantitative genetic methods used to identify these mechanisms are described, with examples from research in childhood, where such studies are now common. Future work will be most effective if it is guided by life-span development frameworks that address these processes, such as the developmental genotype-->environment theory of Scarr and McCartney and the selection/optimization/compensation theory of Baltes and Baltes.

    Recent rapid economic development in the greater Jakarta areas has caused not only increased water resources demands but also affects the water environment due to population increase and land use changes, that further causes land degradation, and changes in hydrologic regimes and environmental qualities. In the present study, the water environmental capacities as indicated by the changing landscapes in the greater Jakarta basins were investigated to understand the role of land use management and its impact on water resources, ecosystem and environmental services. The Ciliwung river basin where rapid population increases and progresses of the land use/cover changes occurring was selected as a representative basin, and 41 water samplings were taken at different time of Jan. 08, Apr. 08, Jul. 08, and Oct. 08 during 2009 to understand the effect of rainfall variation on water quality, and clarify the characteristics of hydrological cycle. Landuse changes of the upper basins as can be seen for the upper basin indicated the expansion of settlements during 1990 to 2004 from 4.1% to 17.6% or in acreage increased almost five times, not only converting forested area, but mostly taking place from paddy fields that contributed about 50% of the additional land for new settlements. Urbanization expanding around the greater Jakarta basins, is closely related to the increased fluctuations of river discharges in recent years, with recurrence floods quickly after heavy rainfall events. Furthermore, the study results indicated that water quality of Ciliwung river, especially the loading concentrations of nitric acid closely reflects the population densities of the watershed. These results suggest that the land use/cover changes of the greater Jakarta basins affect largely the change of water environment of the areas and resulting a deteriorated factor for water resources, ecosystems and environmental services in both of quantity and quality

    The physical environment of the Canadian North is particularly sensitive to changes in climate because of a large concentration of cryospheric elements including both seasonal and multiyear forms of freshwater and sea ice, permafrost, snow, glaciers, and small ice caps. Because the cryosphere responds directly to changes in air temperature and precipitation, it is a primary indicator of the effects of climate variability and change. This article reviews the major changes that have occurred in the recent historical record of these cryospheric components at high latitudes in Canada. Some changes have been less pronounced in the Canadian North than elsewhere, such as changes in sea-ice coverage, whereas others have been potentially more significant, such as ablation of the extensive alpine and high-Arctic small glaciers and ice caps. Projections of future changes are also reviewed for each cryospheric component. Discussion about two other physical components of the North intrinsically linked to the cryosphere is also included, specifically: i) freshwater discharge to the Arctic Ocean via major river networks that are fed primarily by various forms of snow and ice, and ii) the related rise in sea level, which is strongly influenced by ablation of the cryosphere, and coastal stability, which also depends on the thermal integrity of coastal permafrost.

    The failure to integrate environmental and organizational interventions may help explain the lack of success of many change efforts. The high rate of failure for change efforts (50% to 90% failure rates) has been noted by many writers. While specific causes of failure are diverse, a common theme has been failure to consider the organization as a system. That is, either significant aspects of the organization were ignored during the intervention or potential impacts of changes on the elements were overlooked or underestimated. Our own training, technical literature, and professional culture lead us to limited understandings of complex organizations. Change agents must consider all relevant components of organizational performance if interventions are to be meaningful and successful. This study demonstrated the value of an integrated organizational intervention involving redesign of the physical environment, introduction of a new information system, work process improvement, and extended organizational development intervention. The outcomes were extremely positive. The cost of improvement efforts was found to be recaptured within a short time, easily justifying the expenditures. One conclusion from the study is that integrated interventions are very powerful. Integrating improvement of the physical environment with organizational development and technological innovation greatly enhances the likelihood of achieving a successful intervention.

    The Mediterranean region is a "hot-spot" of climate change and wildfires, where about 50000 fires burn 500000 hectares every year. However, in spite of the growing concerns of the climate change impacts on Mediterranean wildfires, there are aspects of this topic that remain largely to be investigated. The main scientific objective of this study is to investigate the climate-driven changes on fires in a typical Mediterranean environment (Catalonia, NE of Spain). To achieve this goal, the following specific aims have been identified: (1) Analysis of the recent evolution of fires; (2) Evaluation of the climate-fire relationship; (3) Estimation of the impacts of observed and future climate change. First, we examine a homogeneous series of forest fires in the period 1970-2010. Our analysis shows that both the burned area and number of fire series display a decreasing trend. After the large fires of 1986 and 1994, the increased effort in fire prevention and suppression could explain part of this decreasing trend. Although it is often stated that fires have increased in Mediterranean regions, the higher efficiency in fire detection could have led to spurious trends and misleading conclusions [1]. Secondly, we show that the interannual variability of summer fires is significantly related to antecedent and concurrent climate conditions, highlighting the importance of climate not only in regulating fuel flammability, but also fuel load. On the basis of these results, we develop a simple regression model that produces reliable out-of-sample predictions of the impact of climate variability on summer forest fires [2]. Finally we apply this model to estimate the impacts of observed climate trends on summer fires and the possible fire response to different regional climate change scenarios. We show that a transition toward warmer conditions has already started to occur and it is possible that they continue by mid-century (under the A1B scenario), and that these changes promote

    Nurse executives must take a leadership role in creating a healthy work environment for nurses and all disciplines. Engaging in partnerships and empowering clinical nurses to construct the solutions to barriers that may stand in the way of the goal of a satisfied and healthy workforce are important strategies toward success. This publication outlines many projects a 3-time Magnet-designated academic hospital has implemented, working with our shared leadership councils, to meet the standards for a healthy work environment. These initiatives, from the unit to the hospital level, included standardizing a culture change of uninterrupted meal breaks, the creation of intensive care unit Zen rooms, strategies to better manage increased patient volumes, best practices for facility design, enhancing physician-nurse relations, and a hospital wellness program. Data were benchmarked against national nurse and employee surveys to compare progress and report outcomes. Two important nursing organization structures that have contributed to the success of a healthy and satisfied nursing work environment include UEXCEL, a longstanding clinical nurse professional practice program, and the hospital's 11-year participation in the University HealthSystem Consortium/American Association of Colleges of Nursing National Post-Baccalaureate Nurse Residency Program. A highly engaged, well-educated, and committed nursing workforce, nurtured by a strong leadership team, has created a positive work environment characterized by low turnover and high retention.

    The family food environment is an important influence in the development of children's dietary habits.

    Devices and programs using digital technology to foster or support behavior change (digital interventions) are increasingly ubiquitous, being adopted for use in patient diagnosis and treatment, self-management of chronic diseases, and in primary prevention. They have been heralded as potentially revolutionizing the ways in which individuals can monitor and improve their health behaviors and health care by improving outcomes, reducing costs, and improving the patient experience. However, we are still mainly in the age of promise rather than delivery. Developing and evaluating these digital interventions presents new challenges and new versions of old challenges that require use of improved and perhaps entirely new methods for research and evaluation. This article discusses these challenges and provides recommendations aimed at accelerating the rate of progress in digital behavior intervention research and practice. Areas addressed include intervention development in a rapidly changing technological landscape, promoting user engagement, advancing the underpinning science and theory, evaluating effectiveness and cost-effectiveness, and addressing issues of regulatory, ethical, and information governance. This article is the result of a two-day international workshop on how to create, evaluate, and implement effective digital interventions in relation to health behaviors. It was held in London in September 2015 and was supported by the United Kingdom's Medical Research Council (MRC), the National Institute for Health Research (NIHR), the Methodology Research Programme (PI Susan Michie), and the Robert Wood Johnson Foundation of the United States (PI Kevin Patrick). Important recommendations to manage the rapid pace of change include considering using emerging techniques from data science, machine learning, and Bayesian approaches and learning from other disciplines including computer science and engineering.

    2012-07-23

    The atmosphere-ocean boundary layer in which sea ice resides includes many complex processes that require a more realistic treatment in GCMs, particularly as models move toward full earth system descriptions. The primary purpose of the workshop was to define and discuss such coupled processes from observational and modeling points of view, including insight from both the Arctic and Antarctic systems. The workshop met each of its overarching goals, including fostering collaboration among experimentalists, theorists and modelers, proposing modeling strategies, and ascertaining data availability and needs. Several scientific themes emerged from the workshop, such as the importance of episodic or extreme events, precipitation, stratification above and below the ice, and the marginal ice zone, whose seasonal Arctic migrations now traverse more territory than in the past.

    A fundamental objective in membrane biology is to understand and predict how a protein sequence folds and orients in a lipid bilayer. Establishing the principles governing membrane protein folding is central to understanding the molecular basis for membrane proteins that display multiple topologies, the intrinsic dynamic organization of membrane proteins, and membrane protein conformational disorders resulting in disease. We previously established that lactose permease of Escherichia coli displays a mixture of topological conformations and undergoes postassembly bidirectional changes in orientation within the lipid bilayer triggered by a change in membrane phosphatidylethanolamine content, both in vivo and in vitro. However, the physiological implications and mechanism of dynamic structural reorganization of membrane proteins due to changes in lipid environment are limited by the lack of approaches addressing the kinetic parameters of transmembrane protein flipping. In this study, real-time fluorescence spectroscopy was used to determine the rates of protein flipping in the lipid bilayer in both directions and transbilayer flipping of lipids triggered by a change in proteoliposome lipid composition. Our results provide, for the first time to our knowledge, a dynamic picture of these events and demonstrate that membrane protein topological rearrangements in response to lipid modulations occur rapidly following a threshold change in proteoliposome lipid composition. Protein flipping was not accompanied by extensive lipid-dependent unfolding of transmembrane domains. Establishment of lipid bilayer asymmetry was not required but may accelerate the rate of protein flipping. Membrane protein flipping was found to accelerate the rate of transbilayer flipping of lipids. PMID:26512118

The remainder of the workshop was discussion, which was broken down into sessions on de ning challenges, applications to host or mobile environments, applications to enterprise network environments, exploring research and operational taxonomies, and determining how to apply scienti c rigor to and investigating the eld of dynamic defense.

  19. Designing for Change: Interoperability in a scaling and adapting environment

    The Earth Science cyberinfrastructure landscape is constantly changing. Technologies advance and technical implementations are refined or replaced. Data types, volumes, packaging, and use cases evolve. Scientific requirements emerge and mature. Standards shift while systems scale and adapt. In this complex and dynamic environment, interoperability remains a critical component of successful cyberinfrastructure. Through the resource- and priority-driven iterations on systems, interfaces, and content, questions fundamental to stable and useful Earth Science cyberinfrastructure arise. For instance, how are sociotechnical changes planned, tracked, and communicated? How should operational stability balance against 'new and shiny'? How can ongoing maintenance and mitigation of technical debt be managed in an often short-term resource environment? The Arctic Data Explorer is a metadata brokering application developed to enable discovery of international, interdisciplinary Arctic data across distributed repositories. Completely dependent on interoperable third party systems, the Arctic Data Explorer publicly launched in 2013 with an original 3000+ data records from four Arctic repositories. Since then the search has scaled to 25,000+ data records from thirteen repositories at the time of writing. In the final months of original project funding, priorities shift to lean operations with a strategic eye on the future. Here we present lessons learned from four years of Arctic Data Explorer design, development, communication, and maintenance work along with remaining questions and potential directions.

    Kelley, Katherine A.; Bellebaum, Katherine L.

    2009-01-01

    Objectives To assess the impact of technology-based changes on student learning, skill development, and satisfaction in a patient-case workshop. Design A new workshop format for a course was adopted over a 3-year period. Students received and completed patient cases and obtained immediate performance feedback in class instead of preparing the case prior to class and waiting for instructors to grade and return their cases. The cases were designed and accessed via an online course management system. Assessment Student satisfaction was measured using end-of-course surveys. The impact of the technology-based changes on student learning, problem-solving, and critical-thinking skills was measured and compared between the 2 different course formats by assessing changes in examination responses. Three advantages to the new format were reported: real-life format in terms of time constraint for responses, a team learning environment, and expedient grading and feedback. Students overwhelmingly agreed that the new format should be continued. Students' examination scores improved significantly under the new format. Conclusion The change in delivery of patient-case workshops to an online, real-time system was well accepted and resulted in enhanced learning, critical thinking, and problem-solving skills.

    Summary Despite wide-spread consensus on the need to transform toxicology and risk assessment in order to keep pace with technological and computational changes that have revolutionized the life sciences, there remains much work to be done to achieve the vision of toxicology based on a mechanistic foundation. A workshop was organized to explore one key aspect of this transformation – the development of Pathways of Toxicity (PoT) as a key tool for hazard identification based on systems biology. Several issues were discussed in depth in the workshop: The first was the challenge of formally defining the concept of a PoT as distinct from, but complementary to, other toxicological pathway concepts such as mode of action (MoA). The workshop came up with a preliminary definition of PoT as “A molecular definition of cellular processes shown to mediate adverse outcomes of toxicants”. It is further recognized that normal physiological pathways exist that maintain homeostasis and these, sufficiently perturbed, can become PoT. Second, the workshop sought to define the adequate public and commercial resources for PoT information, including data, visualization, analyses, tools, and use-cases, as well as the kinds of efforts that will be necessary to enable the creation of such a resource. Third, the workshop explored ways in which systems biology approaches could inform pathway annotation, and which resources are needed and available that can provide relevant PoT information to the diverse user communities.

  5. Detecting Changes of Thermal Environment over the Bohai Coastal Region by Spectral Change Vector Analysis

    2009-12-01

    Change vector analysis (CVA) is an effective approach for detecting and characterizing land-cover change by comparing pairs of multi-spectral and multi-temporal datasets over certain area derived from various satellite platforms. NDVI is considered as an effective detector for biophysical changes due to its sensitivity to red and near infrared signals, while land surface temperature (LST) is considered as a valuable indicator for changes of ground thermal conditions. Here we try to apply CVA over satellite derived LST datasets to detect changes of land surface thermal properties parallel to climate change and anthropogenic influence in a city cluster since 2001. In this study, monthly land surface temperature datasets from 2001-2008 derived from MODIS collection 5 were used to examine change pattern of thermal environment over the Bohai coastal region by using spectral change vector analysis. The results from principle component analysis (PCA) for LST show that the PC 1-3 contain over 80% information on monthly variations and these PCA components represent the main processes of land thermal environment change over the study area. Time series of CVA magnitude combined with land cover information show that greatest change occurred in urban and heavily populated area, featured with expansion of urban heat island, while moderate change appeared in grassland area in the north. However few changes were observed over large plain area and forest area. Strong signals also are related to economy level and especially the events of surface cover change, such as emergence of railway and port. Two main processes were also noticed about the changes of thermal environment. First, weak signal was detected in mostly natural area influenced by interannual climate change in temperate broadleaf forest area. Second, land surface temperature changes were controlled by human activities as 1) moderate change of LST happened in grassland influenced by grazing and 2) urban heat island was

    To evaluate the potential of a 60-minute sexuality diversity workshop to address bullying in secondary schools. Students completed pre- and post-workshop questionnaires. Descriptive statistics were used to summarise results with pre- to immediate post-workshop changes compared using t-tests. Thematic analysis was used to analyse open-ended questionnaire responses. We had 229 students (mean age 13.7 years) attending 10 workshops participate in the study. Three-quarters of students thought the workshop would reduce bullying in schools, and over 95% of the participants thought that other secondary schools should offer the workshop. There was a significant increase in valuing (p < 0.001) and understanding (p < 0.001) sexuality-diverse individuals (e.g. lesbian, gay and bisexual people), between the pre- and post-workshop results. School climates were largely perceived to be 'hard' and included 'bullying/mocking' of sexuality-diverse students; however, many individual students reported a desire to be supportive of their sexuality-diverse peers. Sexuality-based bullying is commonplace in secondary schools. This form of bullying is associated with depression and suicide attempts. Reducing sexuality-based bullying is very likely to have a positive impact on the mental health of young people. Brief workshops, as a part of a wider suite of interventions, have some potential to create safer school environments. © The Royal Australian and New Zealand College of Psychiatrists 2015.

    Category I and II) sources in thousands of devices; and there are many more tens of thousands of smaller sources scattered among thousands of other NRC licensees. As a result of the ubiquitous nature and undeterminable number of current and legacy sources, even in developed countries they can be abandoned, disposed of in a haphazard manner, lost, stolen, and/or otherwise fallout of regulatory control. Supply and demand of sources, being market based, is more or less fluid. Normative security of radioactive sources exists, but varies in each country, and is loosely implemented through non-legally binding recommendations and standards provided by International Atomic Energy Agency technical documents and cooperation and through bilateral efforts such as this workshop where we share best-practices with one another. Much of the reason for the difficulty in securing sealed sources rests in the enormous need for their beneficial applications in the medical, industrial, and agricultural sectors. Alternative technologies to replace high-risk sources continue to be explored, but very few of these alternative solutions have reached the development stage for common usage and distribution. The beneficial uses of sources must be allowed to continue; however, to minimize the potential for their misuse, current controls and regulating mechanisms must be constantly evaluated to ensure the benefits gained outweigh potential risks. From a global perspective, an evaluation and modification of requirements over the entire life cycle of sources from their manufacture to their final disposition is required. The proper removal and disposal of vulnerable disused or orphan sources is essential to maintaining a safe operating environment. One of our goals in this workshop is to share our methodologies for recovering sources and learn how they differ or are similar to the challenges faced in recovering, storing, and disposing of sources in the Republic of Georgia . The suggestions we will make are

    We present an imaging technique allowing locating a small perturbation appearing in a multiple scattering environment. This technique is based on the direct dependence in space and time of the coda decorrelation resulting from the apparition of a supplementary scatterer, which one wishes to image. The inverse problem solution - the location of the defect - is obtained using a maximum likelihood computation. The LOCADIFF technique has been applied to locate a millimeter change in concrete using ultrasounds with a precision of the order of one centimeter [Larose et al., Appl. Phys. Lett. 2010]. The size of the defect is comparable to that of the heterogeneities constituting the sample. We are currently working on a similar technique to locate small velocity perturbations in heterogeneous media, with potential applications on monitoring volcanoes and active faults.

    The drop in oil prices has brought energy policy issues back into discussion. The diversity of policy proposals suggests that clearly defined objectives are needed to avoid quick-fix solutions. The analysis traces the history of policies affecting the US oil industry, then focuses on recent changes in the policy environment. The author weighs recent proposals against those policy objectives he considers appropriate for the US. The three objectives of national security, efficient extraction of energy resources, and economic stability provide a common frame of reference for this purpose. Policymakers should only intervene in the energy market when they can improve the allocation of resources in accordance with these objectives. 3 figures, 3 tables.

  4. Mycotoxins in a changing global environment--a review.

    Mycotoxins are toxic metabolites produced by fungal species that commonly contaminate staple foods and feeds. They represent an unavoidable problem due to their presence in globally consumed cereals such as rice, maize and wheat. Most mycotoxins are immunosuppressive agents and some are carcinogens, hepatotoxins, nephrotoxins, and neurotoxins. Worldwide trends envision a stricter control of mycotoxins, however, the changing global environment may not be the ideal setting to control and reduce the exposure to these toxins. Although new technologies allow us to inspect the multi-mycotoxin presence in foods, new sources of exposure, gaps in knowledge of mycotoxins interactions, appearance of "emergent" mycotoxins and elucidation of consequent health effects can complicate their control even more. While humans are adapting to cope with environmental changes, such as food scarcity, decreased food quality, mycotoxin regulations, crop production and seasonality, and other climate related modifications, fungal species are also adapting and increased cases of mycotoxin adverse health effects are likely to occur in the future. To guarantee access to quality food for all, we need a way to balance global mycotoxin standards with the realistic feasibility of reaching them, considering limitations of producers and designing strategies to reduce mycotoxin exposure based on sound research.

    To be able to meet the demands for care in 2040, dental graduates will need to address challenges resulting from the rapidly changing health care environment with knowledge and sets of skills to build on current standards and adapt to the future. The purposes of this article are to 1) analyze key challenges likely to evolve considerably between now and 2040 that will impact dental education and practice and 2) propose several sets of skills and educational outcomes necessary to address these challenges. The challenges discussed include changes in prevalence of oral diseases, dental practice patterns, materials and technologies, integrated medical-dental care, role of electronic health records, cultural competence, integrated curricula, interprofessional education, specialty-general balance, and web/cloud-based collaborations. To meet these challenges, the dental graduate will need skills such as core knowledge in basic and clinical dentistry, technical proficiency, critical thinking skills for lifelong learning, ethical and professional values, ability to manage a practice, social responsibility, and ability to function in a collegial intra- and interprofessional setting. Beyond the skills of the individual dentist will be the need for leadership in academia and the practice community. Academic and professional leaders will need to engage key constituencies to develop strategic directions and agendas with all parties pointed toward high standards for individual patients and the public at large.

  6. Street environment change detection from mobile laser scanning point clouds

    NASA Astrophysics Data System (ADS)

    2015-09-01

    Mobile laser scanning (MLS) has become a popular technique for road inventory, building modelling, infrastructure management, mobility assessment, etc. Meanwhile, due to the high mobility of MLS systems, it is easy to revisit interested areas. However, change detection using MLS data of street environment has seldom been studied. In this paper, an approach that combines occupancy grids and a distance-based method for change detection from MLS point clouds is proposed. Unlike conventional occupancy grids, our occupancy-based method models space based on scanning rays and local point distributions in 3D without voxelization. A local cylindrical reference frame is presented for the interpolation of occupancy between rays according to the scanning geometry. The Dempster-Shafer theory (DST) is utilized for both intra-data evidence fusion and inter-data consistency assessment. Occupancy of reference point cloud is fused at the location of target points and then the consistency is evaluated directly on the points. A point-to-triangle (PTT) distance-based method is combined to improve the occupancy-based method. Because it is robust to penetrable objects, e.g. vegetation, which cause self-conflicts when modelling occupancy. The combined method tackles irregular point density and occlusion problems, also eliminates false detections on penetrable objects.

    2011-06-01

    A National Post-Irradiation-Examination (PIE) Workshop was held March 29-30, 2011, in Washington D.C., stimulated by the DOE Acting Assistant Secretary for Nuclear Energy approval on January 31, 2011 of the “Mission Need Statement for Advanced Post-Irradiation Examination Capability”. As stated in the Mission Need, “A better understanding of nuclear fuels and material performance in the nuclear environment, at the nanoscale and lower, is critical to the development of innovative fuels and materials required for tomorrow’s nuclear energy systems.” (2011) Developing an advanced post-irradiation capability is the most important thing we can do to advance nuclear energy as an option to meeting national energy goals. Understanding the behavior of fuels and materials in a nuclear reactor irradiation environment is the limiting factor in nuclear plant safety, longevity, efficiency, and economics. The National PIE Workshop is part of fulfilling or addressing Department of Energy (DOE) missions in safe and publically acceptable nuclear energy. Several presentations were given during the opening of the workshop. Generally speaking, these presentations established that we cannot continue to rely on others in the world to provide the capabilities we need to move forward with nuclear energy technology. These presentations also generally identified the need for increased microstructural understanding of fuels and materials to be coupled with modeling and simulation, and increased accessibility and infrastructure to facilitate the interaction between national laboratories and participating organizations. The overall results of the work of the presenters and panels was distilled into four primary needs 1. Understanding material changes in the extreme nuclear environment at the nanoscale. Nanoscale studies have significant importance due to the mechanisms that cause materials to degrade, which actually occur on the nanoscale. 2. Enabling additional proficiency in

    Regional climate and local weather conditions can profoundly influence life history parameters (growth, survival, fecundity) and population dynamics in northern ungulates (Post and Stenseth 1999, Coulson et al. 2001). The influence is both direct, for example through reduced growth or survival (Aanes et al. 2000, Tyler et al. 2008), and indirect, for example through changes in resource distribution, phenology and quality, changes which subsequently influence consumer dynamics (Post et al. 2008). By comparing and contrasting data from three spatially independent populations of ungulates, I discuss how variation in local weather parameters and vegetation growth influence spatial and temporal dynamics through changes in life history parameters and/or behavioural dynamics. The data originate from long term (11-15 years) monitoring data from three populations of ungulates in one subarctic and two high Arctic sites; semi-domesticated reindeer (Rangifer tarandus tarandus) in northern Norway, Svalbard reindeer (R. t. platyrhynchus) on Spitsbergen and muskoxen (Ovibos moschatus) in Northeast Greenland. The results show that juvenile animals can be particularly vulnerable to changes in their environment, and that this is mirrored to different degrees in the spatio-temporal dynamics of the three populations. Adverse weather conditions, acting either directly or mediated through access to and quality of vegetation, experienced by young early in life, or even by their dams during pregnancy, can lead to reduced growth, lower survival and reduced reproductive performance later in life. The influence of current climatic variation, and the predictions of how local weather conditions may change over time, differs between the three sites, resulting in potentially different responses in the three populations.

    Stone monuments are degraded by both climate and pollution. Deterioration by pollution was especially intense from the 1700s and until the late 20th century the dominant impact of air pollution was the sulfation of surfaces. The parallel deposition of soot caused blackening and on some surfaces dark coloured crusts. The decrease of sulfur and soot from coal combustion during the last decades of the 20th century led to cleaner air in cities, a decrease of pollution-decay rates on building stones and a public desire for cleaner buildings. Although there were decreases in SO2, it was replaced by ozone, nitrogen oxides and particles richer in organic compounds, the result of an extensive use of automobiles. Deposited organic compounds can oxidise in modern urban environments in a yellowing process. The future may reveal variation in building colour from biological growth in a changing climate. In urban atmospheres with less sulfur, biological growth is more effective. A greater rate of delivery of nitrate to building surfaces that acts as "airborne fertiliser" favours colonisation. Depending on climate, there might be different processes (e.g. greening or reddening) and patterns of colouration. Climate is also a relevant factor in the weathering of monuments. Recent research suggests the concept of Heritage Climatology in the study of climate interactions with monuments, materials and sites. These parameters concentrate on aspects and combinations of meteorological variables that relate to material damage. The Köppen-Geiger climate classification can be a good approximation for some heritage risks. For instance, the number of salt transitions shows distinct seasonality which can be related to Köppen-Geiger climate types and their change during the 21th century. The study of changing pollution and climate impacts on the built heritage needs the output of pollution emissions and climate change models, which are prone to uncertainties.

    Our modern age is defined by an astounding capacity to generate scientific information. From DNA to dark matter, human ingenuity and technologies create an endless stream of data about ourselves and the world of which we are a part. Yet we largely founder in transforming information into understanding, and understanding into rational action for our society as a whole. Earth and biodiversity scientists are especially frustrated by this impasse because the data they gather often point to a clash between Earth's capacity to sustain life and the decisions that humans make to garner the planet's resources. Immersive virtual environments offer an underexplored link in the translation of scientific data into public understanding, dialogue, and action. The Worldviews Network is a collaboration of scientists, artists, and educators focused on developing best practices for the use of immersive environments for science-based ecological literacy education. A central tenet of the Worldviews Network is that there are multiple ways to know and experience the world, so we are developing scientifically accurate, geographically relevant, and culturally appropriate programming to promote ecological literacy within informal science education programs across the United States. The goal of Worldviews Network is to offer transformative learning experiences, in which participants are guided on a process integrating immersive visual explorations, critical reflection and dialogue, and design-oriented approaches to action - or more simply, seeing, knowing, and doing. Our methods center on live presentations, interactive scientific visualizations, and sustainability dialogues hosted at informal science institutions. Our approach uses datasets from the life, Earth, and space sciences to illuminate the complex conditions that support life on earth and the ways in which ecological systems interact. We are leveraging scientific data from federal agencies, non-governmental organizations, and our

    The Mars Telescopic Observations Workshop, held August 14-15, 1995, at Cornell University in Ithaca, New York, was organized and planned with two primary goals in mind: The first goal was to facilitate discussions among and between amateur and professional observers and to create a workshop environment fostering collaborations and comparisons within the Mars observing community. The second goal was to explore the role of continuing telescopic observations of Mars in the upcoming era of increased spacecraft exploration. The 24 papers presented at the workshop described the current NASA plans for Mars exploration over the next decade, current and recent Mars research being performed by professional astronomers, and current and past Mars observations being performed by amateur observers and observing associations. The workshop was divided into short topical sessions concentrating on programmatic overviews, groundbased support of upcoming spacecraft experiments, atmospheric observations, surface observations, modeling and numerical studies, and contributions from amateur astronomers.

    Both the stress of exercise and the stress of a cold environment have been shown to increase the mobilization and utilization of body fat, thereby reducing body fat stores. Much of the research has been done on either rats or male human subjects. The purpose of this research was to show the physiological changes which occur to young, relatively obese, women who exercised during five consecutive days, for 200 min per day, in each of three environmental, chamber conditions: (1) warm-warm (WW), +15‡C; (2) cold-cold (CC), -20‡C; and (3) cold-warm (CW), -20‡C ambient temperature, with +18‡C air pumped to face masks for warmed air breathing. Oxygen cost of exercise, respiratory quotients, energy intake and utilization, and body composition changes were measured before, during, and after each environmental condition. While the respiratory quotients and the skinfold measurements decreased in the colder conditions, the underwater weighing determined percentage body fat did not show the same decrement as the skinfold measures, indicating a possible translocation of body fat from the subcutaneous depots to the deep body fat depots. Body mass loss was significant (P<0.05) only in the WW condition. Thermogenesis would have been centred in the skeletal muscle and liver during the CW condition; however, with facial and upper airway cooling in the CC condition; brown adipose tissue (BAT) hypertrophy may be postulated at this more intense level of cold stress. Due to a greater stability of depot fat in the female, a longer cold exposure would be required to observe the fully developed BAT thermogenesis which would follow after the consequences of fat translocation which we have documented.

    The present experiment provided a replication in humans of an experimental procedure that has been used frequently with nonhumans to investigate choice behaviour in a changing environment. Six volunteers played a computer game, which required tracking of a moving balloon on two simultaneously available response panels for monetary reinforcers. Each of the 15 sessions randomly arranged the following concurrent variable-interval reinforcement schedules, which were in effect until six reinforcers had been obtained: 27:1, 9:1, 3:1, 1:1, 1:3, 1:9, and 1:27. Although many aspects of human performance appeared to be qualitatively similar to that of nonhumans on this procedure, such as the rapid preference shifts towards the within-session reinforcer ratios and the presence of local effects of reinforcers, values of sensitivity to reinforcement were very variable in the present study, as commonly reported in human choice studies. Future variations and refinements of the experimental methods are needed to explore how this variability may be reduced. 2009 Elsevier B.V. All rights reserved.

  1. Evolution of migration in a periodically changing environment.

    PubMed

    Blanquart, F; Gandon, S

    2011-02-01

    The ability to migrate can evolve in response to various forces. In particular, when selection is heterogeneous in space but constant in time, local adaptation induces a fitness cost on immigrants and selects against migration. The evolutionary outcome, however, is less clear when selection also varies temporally. Here, we present a two-locus model analyzing the effects of spatial and temporal variability in selection on the evolution of migration. The first locus is under temporally varying selection (various periodic functions are considered, but a general nonparametric framework is used), and the second locus is a modifier controlling migration ability. First, we study the dynamics of local adaptation and derive the migration rate that maximizes local adaptation as a function of the speed and geometry of the fluctuations in the environment. Second, we derive an analytical expression for the evolutionarily stable migration rate. When there is no cost of migration, we show that higher migration rates are favored when selection changes fast. When migration is costly, however, the evolutionarily stable migration rate is maximal for an intermediate speed of the variation of selection. This model may help in understanding the evolution of migration in a broad range of scenarios and, in particular, in host-parasite systems, where selection is thought to vary quickly in both space and time.

    The hydrologic design of nonstationary flood extremes is an emerging field that is essential for water resources management and hydrologic engineering design to cope with changing environment. This paper aims to investigate and compare the capability of four nonstationary hydrologic design strategies, including the expected number of exceedances (ENE), design life level (DLL), equivalent reliability (ER), and average design life level (ADLL), with the last three methods taking into consideration the design life of the project. The confidence intervals of the calculated design floods were also estimated using the nonstationary bootstrap approach. A comparison of these four methods was performed using the annual maximum flood series (AMFS) of the Weihe River basin, Jinghe River basin, and Assunpink Creek basin. The results indicated that ENE, ER and ADLL yielded the same or very similar design values and confidence intervals for both increasing and decreasing trends of AMFS considered. DLL also yields similar design values if the relationship between DLL and ER/ADLL return periods is considered. Both ER and ADLL are recommended for practical use as they have associated design floods with the design life period of projects and yield reasonable design quantiles and confidence intervals. Furthermore, by assuming that the design results using either a stationary or nonstationary hydrologic design strategy should have the same reliability, the ER method enables us to solve the nonstationary hydrologic design problems by adopting the stationary design reliability, thus bridging the gap between stationary and nonstationary design criteria.

    2004-01-01

    Molecular evolution has become the nexus of many areas of biological research. It both brings together and enriches such areas as biochemistry, molecular biology, microbiology, population genetics, systematics, developmental biology, genomics, bioinformatics, in vitro evolution, and molecular ecology. The Workshop provides an important contribution to these fields in that it promotes interdisciplinary research and interaction, and thus provides a glue that sticks together disparate fields. Due to the wide range of fields addressed by the study of molecular evolution, it is difficult to offer a comprehensive course in a university setting. It is rare for a single institution to maintain expertise in all necessary areas. In contrast, the Workshop is uniquely able to provide necessary breadth and depth by utilizing a large number of faculty with appropriate expertise. Furthermore, the flexible nature of the Workshop allows for rapid adaptation to changes in the dynamic field of molecular evolution. For example, the 2003 Workshop included recently emergent research areas of molecular evolution of development and genomics.

    2015-04-01

    The Soil Crust INternational (SCIN) project aims to achieve improved appreciation of the importance and functioning of Biological Soil Crusts (BSC) in Europe. Four sites throughout Europe were identified for having important, yet diverse BSC communities: Gössenheim in Germany, Almeria in Spain, Öland in Sweden and Hochtor in Austria. These sites vary greatly in geographic and environmental conditions; and constitute, along with cyanobacteria, algae, bryophytes and fungi a host of green algal and cyanobacterial lichen species. Many of the lichen species occur in two-four locations, despite the climatic differences, and it has been observed that species are morphologically distinctive between sites. Lichens may be adapted to different environmental conditions by symbiosis with photobionts that are suited to the local conditions. Therefore, we may expect to find that a lichen species that can survive in diverse habitats to be less photobiont specific than species with a narrow range. In recent years it has been discovered that lichens can switch their photobiont throughout the course of their lives. Whether lichens can associate with an available photobiont and switch when a preferred photobiont becomes available is not conclusively known, or whether as habitats are affected by climate change, lichens will be able to switch to a new photobiont to survive changing conditions. A transplantation experiment of lichens between biomes was installed in each of the SCIN sites to investigate the potential of different lichen species to assimilate to a new environment. Where the same lichen species occurred in 2 or more locations samples were transplanted from their natural location to the foreign for a period of 2 years. Controls were also applied; this consisted of samples being transplanted within their own site to assess the effect of the transplantation itself. The photobionts of key species are sequenced to analyse diversity of photobiont interactions within/between the

    1996-01-01

    A distinguishing feature of American health care is its emphasis on advanced technology. Yet today's changing health care environment is overhauling the engine of technological innovation. The rate and direction of technological innovation are affected by a complex of supply- and demandside factors, including biomedical research, education, patent law, regulation, health care payment, tort law, and more. Some distinguishing features of technological innovation in health care are now at increased risk. Regulatory requirements and rising payment hurdles are especially challenging to small technology companies. Closer management of health care delivery and payment, particularly the standardization that may derive from practice guidelines and clamping down on payment for investigational technologies, curtails opportunities for innovation. Levels and distribution of biomedical research funding in government and industry are changing. Financial constraints are limiting the traditional roles of academic health centers in fostering innovation. Despite notable steps in recent years to lower regulatory barriers and speed approvals, especially for products for life-threatening conditions, the Food and Drug Administration is under great pressure from Congress, industry, and patients to do more. Technology gatekeeping is shifting from hundreds of thousands of physicians acting on behalf of their patients to fewer, yet more powerful, managed care organizations and health care networks. Beyond its direct effects on adoption, payment, and use of technologies, the extraordinary buying leverage of these large providers is cutting technology profit margins and heightening competition among technology companies. It is contributing to unprecedented restructuring of the pharmaceutical and medical device industries, leading to unprecedented alliances with generic product companies, health care providers, utilization review companies, and other agents. These industry changes are already

    The author has identified the following significant results. Four change detection techniques were designed and implemented for evaluation: (1) post classification comparison change detection, (2) delta data change detection, (3) spectral/temporal change classification, and (4) layered spectral/temporal change classification. The post classification comparison technique reliably identified areas of change and was used as the standard for qualitatively evaluating the other three techniques. The layered spectral/temporal change classification and the delta data change detection results generally agreed with the post classification comparison technique results; however, many small areas of change were not identified. Major discrepancies existed between the post classification comparison and spectral/temporal change detection results.

    Petrov, A. N.

    2016-12-01

    The Taimyr Reindeer Herd (TRH) is both the largest and the longest monitored wild reindeer herd in Eurasia. An important part of Arctic ecosystems and Indigenous livelihood, wild reindeer have been continuously monitored for almost 50 years. During this time, herds have exhibited large changes in size and these changes have been recorded in almost all herds across the animal's range. An increasing number of wild reindeer in the Soviet times was followed by a significant population loss in the last decade. In addition, recent monitoring revealed substantial shifts in the distribution of wild populations. The decline in wild reindeer is likely related to natural cycles and changes in the Arctic environment caused by climate variability and anthropogenic activity. This study investigates patterns and possible drives of reindeer population dynamics in space and time. We identify key climatic factors, possible relationships with biomass dynamics, as well as with hunting practices and other human impacts.

    OBJECTIVE We examined the hypothesis that elementary school-age children will be more physically active while attending school in a novel, activity-permissive school environment compared to their traditional school environment RESEARCH METHODS AND PROCEDURES Twenty-four children were monitored with a single triaxial accelerometer worn on the thigh. The students attended school in three different environments: traditional school with chairs and desks, an activity-permissive environment, and finally their traditional school with desks which encouraged standing. Data from the school children was compared with another group of age-matched children (n = 16) whose physical activity was monitored during summer vacation. RESULTS When children attended school in their traditional environment, they moved an average (mean ± standard deviation) 71 ± 0.4 m/s2. When the children attended school in the activity-permissive environment, they moved an average of 115 ± 3 m/s2. The children moved 71 ± 0.7 m/s2 while attending the traditional school with standing desks. Children moved significantly more while attending school in the activity-permissive environment compared to the amount that they moved in either of the traditional school environments (P<0.0001 for both). Comparing children’s activity while they were on summer vacation (113 ± 8 m/s2) to school-bound children in their traditional environment showed significantly more activity for the children on summer vacation (P<0.0001). The school children in the activity-permissive environment were as active as children on summer vacation. DISCUSSION Children will move more in an activity-permissive environment. Strategies to increase the activity of school children may involve re-designing the school itself. PMID:18535550

    American Astronomical Society Teacher Resource Agent Institutes were held in the summers of 1994-1996. From the 215 Agents, sixteen were selected to attend a follow-up leadership workshop for three weeks in July, 1997 at University of Texas at Austin. The workshop followed the recommendations of both the AASTRA formative evaluator and the National Science Education Standards in allowing the participants time to reflect on their practice as teachers and as teacher-leaders. At no financial charge to the project, the Southwest Educational Development Laboratory contributed three workshops of three hours each. These workshops, plus one given by the PI, were taken from "Facilitating Systemic Change in Science and Mathematics Education : A Toolkit for Professional Developers" [ISBN 1-878234-08-0]. In addition, McDonald Observatory contributed six nights of telescope time on the 30-inch telescope with a CCD prime focus camera. In Austin, several astronomers lectured on their research; most of the lectures correlated with the research projects in progress at the Observatory during the teachers' observing run. Several observers allowed the teachers to participate in their observing sessions on the larger telescopes. Participant evaluation of the Leadership Workshop was very positive, both in terms of enhancing their self-image as leaders, enriching their repertoire of activities to use within their classrooms, and introducing them to modern astronomical research techniques. AASTRA is supported by NSF under grant ESI 93- 53377 and the AAS. Additional support is provided by Loyola University of Chicago, Northern Arizona University of Flagstaff, University of Maryland at College Park, and the University of Texas at Austin.

  12. Prediction under change: invariant model parameters in a varying environment

    Hydrological understanding is commonly synthesised into complex mechanistic models, some of which have become "as inscrutable as nature itself" (Harte, 2002). Parameters for most models are estimated from past observations. This may result in an ill-posed problem with associated "equifinality" (Beven, 1993), in which the information content in calibration data is insufficient for distinguishing a suitable parameter set among all possible sets. Consequently, we are unable to identify the "correct" parameter set that produces the right results for the right reasons. Incorporation of new process knowledge into a model adds new parameters that exacerbate the equifinality problem. Hence improved process understanding has not necessarily translated into improved models nor contributed to better predictions. Prediction under change confronts us with additional challenges: 1. Varying boundary conditions: Projections into the future can no longer be guided by observations in the past to the same degree as they could when the boundary conditions were considered stationary. 2. Ecohydrological adaptation: Common model parameters related to vegetation properties (e.g. canopy conductance, rooting depths) cannot be assumed invariant, as vegetation dynamically adapts to its environment. 3. No analog conditions for model evaluation: Climate change and in particular rising atmospheric CO2 concentrations will lead to conditions that cannot be found anywhere on Earth at present. Therefore it is doubtful whether the ability of a hydrological model to reproduce the past is indicative of its trustworthiness for predicting the future. We propose that optimality theory can help addressing some of the above challenges. Optimality theory submits that natural systems self-optimise to attain certain goal functions (or "objective functions"). Optimality principles allow an independent prediction of system properties that would otherwise require direct observations or calibration. The resulting

    The Space Studies Board of the National Research Council provided a series of recommendations to NASA on planetary protection requirements for future Mars sample return missions. One of the Board's key findings suggested, although current evidence of the martian surface suggests that life as we know it would not tolerate the planet's harsh environment, there remain 'plausible scenarios for extant microbial life on Mars.' Based on this conclusion, all samples returned from Mars should be considered potentially hazardous until it has been demonstrated that they are not. In response to the National Research Council's findings and recommendations, NASA has undertaken a series of workshops to address issues regarding NASA's proposed sample return missions. Work was previously undertaken at the Mars Sample Handling and Protocol Workshop 1 (March 2000) to formulate recommendations on effective methods for life detection and/or biohazard testing on returned samples. The NASA Planetary Protection Officer convened the Mars Sample Sterilization Workshop, the third in the Mars Sample Handling Protocol Workshop Series, on November 28-30, 2000 at the Holiday Inn Rosslyn Westpark, Arlington, Virginia. Because of the short timeframe between this Workshop and the second Workshop in the Series, which was convened in October 2000 in Bethesda, Maryland, they were developed in parallel, so the Sterilization Workshop and its report have therefore been designated as '2a'). The focus of Workshop 2a was to make recommendations for effective sterilization procedures for all phases of Mars sample return missions, and to answer the question of whether we can sterilize samples in such a way that the geological characteristics of the samples are not significantly altered.

    Calibration and validation are fundamental for obtaining quantitative information from Earth Observation (EO) sensor data. Recognising this and the impending launch of at least five sensors in the next five years, the International Spaceborne Imaging Spectroscopy Technical Committee instigated a calibration and validation initiative. A workshop was conducted recently as part of this initiative with the objective of establishing a good practice framework for radiometric and spectral calibration and validation in support of spaceborne imaging spectroscopy missions. This paper presents the outcomes and recommendations for future work arising from the workshop.

    Adaptive Optics has been the centre piece of ING's development programme for some years now. First results of the NAOMI AO system at the WHT have been presented in earlier issues of this newsletter. As ING is climbing the steep learning curve of adaptive optics, the time was considered ripe to compare our experience at the WHT with that of other telescopes with many more years of experience. In order to keep the workshop well focussed and encourage the best opportunities for debating results only a small number of participants were invited to attend.

    2015-05-01

    The aim was to investigate how physical activity and the perceived neighborhood environment in children change when they enter adolescence. Also the relation between changes in the perceived environment and changes in children's physical activity was investigated. In total, 321 children and one of their parents filled out a physical activity questionnaire and the NEWS-Y at two time points (last grade of elementary school and 2 years later). Children also wore an activity monitor. Changes in children's physical activity were dependent on the physical activity domain. Only less than half of children's perceived neighborhood factors changed and about half of the parental perceived neighborhood factors changed. Most of these factors changed towards higher activity friendliness. Changes in the perceived environment were only limitedly related to changes in children's physical activity.

    Bushfires are an integral part of the Australian environment. While the immediate health impacts of these fires can be devastatingly obvious, there are many other serious aspects of bushfires that remain less well understood. A holistic perspective of bushfires is essential for minimising harm and ensuring public safety in an environment that is becoming increasingly conducive to major bushfire catastrophes. This review summarises the current evidence about the immediate health risks of bushfires and the special health needs of survivors. It also looks at the health risks of smoke haze and other environmental hazards associated with bushfires.

    This paper investigates the utility of multispectral Landsat Thematic Mapper satellite data for documenting changes to a Caribbean coastal zone using the change vector analysis processing technique. The area of study was the coastal region near the village of Buen Hombre on the north coast of the Dominican Republic. The change vector analysis techniques uses any number of spectral bands from multidate satellite data to produce change images that yield information about both the magnitude and direction of differences in pixel values (which are proportional to radiance). The final products were created by appending color-coded change pixels onto a black-and-white base map. The advantages and limitations of the technique for coastal inventories are discussed. 9 refs.

    We are facing a dynamic future in the face of multiple stressors acting individually and in combination: climate change; habitat change/loss; overfishing; invasive species; harmful algal blooms/eutrophication; and, chemical contaminants. Historic assessment and management approaches will be inadequate for addressing risks from climate change and other stressors. Wicked problems (non-linear, complex, competing risks and benefits, not easily solvable), will become increasingly common. We are facing irreversible changes to our planetary living conditions. Agreed protection goals and considering both the negatives (risks) and the positives (benefits) of all any and all actions are required, as is judicious and appropriate use of the Precautionary Principle. Researchers and managers need to focus on: determining tipping points (alternative stable points); maintaining ecosystem services; and, managing competing ecosystem services. Marine (and other) scientists are urged to focus their research on wicked problems to allow for informed decision-making on a planetary basis.

    2014-04-15

    Fibro-adipogenic progenitors (FAPs) reside in the muscle, where they facilitate myofiber regeneration. Under normal conditions, FAPs lack myogenic potential and thus do not directly contribute to regenerated myofibers. Surprisingly, Saccone and colleagues (pp. 841-857) demonstrated that the dystrophic muscle environment causes FAPs to adopt a chromatin state that imparts these cells with myogenic potential. In this context, treatment of muscle with deacetylase inhibitors activates a BAF60c-myomiR transcriptional network in FAPs, blocking adipogenesis and driving muscle differentiation.

Conservationists have paid attention to genetic homogenization caused by human-induced translocations (e.g. biological invasions and stocking), and to the importance of environmental heterogeneity for the ecological coexistence of species. However, far less attention has been paid to the consequences of loss of environmental heterogeneity to the genetic coexistence of sympatric species. Our review of empirical observations and our theoretical considerations on the causes and consequences of interspecific hybridization suggest that a loss of environmental heterogeneity causes a loss of biodiversity through increased genetic admixture, effectively reversing speciation. Loss of heterogeneity relaxes divergent selection and removes ecological barriers to gene flow between divergently adapted species, promoting interspecific introgressive hybridization. Since heterogeneity of natural environments is rapidly deteriorating in most biomes, the evolutionary ecology of speciation reversal ought to be fully integrated into conservation biology.

    Making changes to the way food is produced, distributed, and processed is one strategy for addressing global climate change. In this case study, we examine the "forming" stage of an emergent and locally-based coalition that is both participatory and focused on promoting food security by creating food systems change. Social network analysis is used to compare network density, centrality, and centralization among coalition partners before the formation of the coalition and at its one-year anniversary. Findings reveal that the coalition facilitated information seeking, assistance seeking, and collaborative efforts related to food security among a group of organizational stakeholders that were relatively disconnected pre-coalition. Results also illuminate tensions related to increased centralization of the network, coalition efficiency, and the goals of democratic decision-making. This study highlights the utility of social network analysis as a tool for evaluating the aims and trajectory of locally-based coalitions focused on global concerns.

  13. Maintaining space shuttle safety within an environment of change

    Greenfield, Michael A.

    1999-09-01

    In the 10 years since the Challenger accident, NASA has developed a set of stable and capable processes to prepare the Space Shuttle for safe launch and return. Capitalizing on the extensive experience gained from a string of over 50 successful flights, NASA today is changing the way it does business in an effort to reduce cost. A single Shuttle Flight Operations Contractor (SFOC) has been chosen to operate the Shuttle. The Government role will change from direct "oversight" to "insight" gained through understanding and measuring the contractor's processes. This paper describes the program management changes underway and the NASA Safety and Mission Assurance (S&MA) organization's philosophy, role, and methodology for pursuing this new approach. It describes how audit and surveillance will replace direct oversight and how meaningful performance metrics will be implemented.

    Rebuilding depleted fish stocks is an international policy goal and a 2020 Aichi target under the Convention on Biological Diversity. However, stock productivity may shift with future climate change, with unknown consequences for sustainable harvesting, biomass targets and recovery timelines. Here we develop a stochastic modelling framework to characterize variability in the intrinsic productivity parameter (r) and carrying capacity (K) for 276 global fish stocks worldwide. We use models of dynamic stock productivity fitted via Bayesian inference to forecast rebuilding timelines for depleted stocks. In scenarios without fishing, recovery probabilities are reduced by 19%, on average, relative to models assuming static productivity. Fishing at 90% of the maximum sustainable rate depresses recovery probabilities by 42%, on average, relative to static models. This work reveals how a changing environmental context can delay the rebuilding of depleted fish stocks, and provides a framework to account for the potential impacts of environmental change on the productivity of wildlife populations more broadly.

    The potential was discussed for welding in space, its advantages and disadvantages, and what type of programs can benefit from the capability. Review of the various presentations and comments made in the course of the workshop suggests several routes to obtaining a better understanding of how welding processes can be used in NASA's initiatives in space. They are as follows: (1) development of a document identifying well processes and equipment requirements applicable to space and lunar environments; (2) more demonstrations of welding particular hardware which are to be used in the above environments, especially for space repair operations; (3) increased awareness among contractors responsible for building space equipment as to the potential for welding operations in space and on other planetary bodies; and (4) continuation of space welding research projects is important to maintain awareness within NASA that welding in space is viable and beneficial.

    Measuring the small changes associated with long-term global climate change from space is a daunting task. To address these problems and recommend directions for improvements in satellite instrument calibration some 75 scientists, including researchers who develop and analyze long-term data sets from satellites, experts in the field of satellite instrument calibration, and physicists working on state of the art calibration sources and standards met November 12 - 14, 2002 and discussed the issues. The workshop defined the absolute accuracies and long-term stabilities of global climate data sets that are needed to detect expected trends, translated these data set accuracies and stabilities to required satellite instrument accuracies and stabilities, and evaluated the ability of current observing systems to meet these requirements. The workshop's recommendations include a set of basic axioms or overarching principles that must guide high quality climate observations in general, and a roadmap for improving satellite instrument characterization, calibration, inter-calibration, and associated activities to meet the challenge of measuring global climate change. It is also recommended that a follow-up workshop be conducted to discuss implementation of the roadmap developed at this workshop.

    2013-01-01

    Behavioural innovations are increasingly thought to provide a rich source of phenotypic plasticity and evolutionary change. Innovation propensity shows substantial variation across avian taxa and provides an adaptive mechanism by which behaviour is flexibly adjusted to changing environmental conditions. Here, we tested for the first time the prediction that inter-individual variation in innovation propensity is equally a measure of behavioural flexibility. We used Indian mynas, Sturnus tristis, a highly successful worldwide invader. Results revealed that mynas that solved an extractive foraging task more quickly learnt to discriminate between a cue that predicted food, and one that did not more quickly. However, fast innovators were slower to change their behaviour when the significance of the food cues changed. This unexpected finding appears at odds with the well-established view that avian taxa with larger brains relative to their body size, and therefore greater neural processing power, are both faster, and more flexible learners. We speculate that the existence of this relationship across taxa can be reconciled with its absence within species by assuming that fast, innovative learners and non innovative, slow, flexible learners constitute two separate individual strategies, which are both underpinned by enhanced neural processing power. This idea is consistent with the recent proposal that individuals may differ consistently in ‘cognitive style’, differentially trading off speed against accuracy in cognitive tasks. PMID:24391981

    Four generations of CAD/CAM systems can be identified, corresponding to changes in both modeling functionality and software architecture. The systems evolved from 2D and wireframes to solid modeling, to parametric/variational modelers to the current simulation-embedded systems. Recent developments have enabled design engineers to perform many of the complex analysis tasks, typically performed by analysis experts. Some of the characteristics of the current and emerging CAD/CAM/CAE systems are described in subsequent presentations. The focus of the workshop is on the potential of CAD/CAM/CAE systems for use in simulating the entire mission and life-cycle of future aerospace systems, and the needed development to realize this potential. First, the major features of the emerging computing, communication and networking environment are outlined; second, the characteristics and design drivers of future aerospace systems are identified; third, the concept of intelligent synthesis environment being planned by NASA, the UVA ACT Center and JPL is presented; and fourth, the objectives and format of the workshop are outlined.

    Summary Most marine organisms make functional biomolecular materials that extend to varying degrees ‘beyond their skins’. These materials are very diverse and include shells, spines, frustules, tubes, mucus trails, egg capsules and byssal threads, to mention a few. Because they are devoid of cells, these materials lack the dynamic maintenance afforded intra-organismic tissues and thus are usually assumed to be inherently more durable than their internalized counterparts. Recent advances in nanomechanics and submicron spectroscopic imaging have enabled the characterization of structure–property relationships in a variety of extra-organismic materials and provided important new insights about their adaptive functions and stability. Some structure–property relationships in byssal threads are described to show how available analytical methods can reveal hitherto unappreciated interdependences between these materials and their prevailing chemical, physical and ecological environments.

  10. Changing heartbeat perception to induce anxiety in virtual environments.

    Chittaro, Luca

    2012-01-01

    In this paper, we first propose a general technique to induce anxiety in virtual environments (VEs) which exploits auditory heartbeat perception and biofeedback. Then, we consider a VE that reproduces a real-world anxiety-inducing experience (being suddenly surrounded by smoke during a fire evacuation of a building), and we describe an experiment that contrasts 3 conditions: (i) an augmentation of the VE with a bar that indicates when the user's avatar gets hurt, (ii) an augmentation of the VE with the typical audio visual stimuli which are employed in violent videogames when the user's avatar gets hurt, (iii) introduction of the proposed biofeedback technique in the previous condition. We carry out an electrodermal analysis showing that the introduction of the proposed technique produces much higher physiological arousal in terms of skin conductance level (SCL) than the other two conditions. Subjective measures of users' state anxiety are consistent with the recorded physiological reactions.

  12. The dynamic replicon: adapting to a changing cellular environment.

    PubMed

    Herrick, John

    2010-02-01

    Eukaryotic cells are often exposed to fluctuations in growth conditions as well as endogenous and exogenous stress-related agents. During development, global patterns of gene transcription change substantially, and these changes are associated with altered patterns of DNA replication and larger distances between replication origins in somatic cells compared to embryos. Conversely, when cells experience difficulties while replicating DNA, the replication program is dramatically altered and distances between replication origins decrease. Recent evidence indicates that each unit of replication, or replicon, can correspond to one or more potential replication origins, but in the case of multiple potential origins, only one is selected to initiate replication of the replicon. How one origin is selected from multiple potential origins and how origin densities are regulated during genome duplication remains unclear. The following review addresses some of the mechanisms involved in regulating replication origins during both a normal and perturbed eukaryotic cell cycle.

    Climate change is expected to be a top driver of global biodiversity loss in the 21st century. It poses new challenges to conserving and managing imperiled species, particularly in marine and estuarine ecosystems. The use of climate-related science in statutorily driven species management, such as under the U.S. Endangered Species Act (ESA), is in its early stages. This article provides an overview of ESA processes, with emphasis on the mandate to the National Marine Fisheries Service (NMFS) to manage listed marine, estuarine, and anadromous species. Although the ESA is specific to the United States, its requirements are broadly relevant to conservation planning. Under the ESA, species, subspecies, and "distinct population segments" may be listed as either endangered or threatened, and taking of most listed species (harassing, harming, pursuing, wounding, killing, or capturing) is prohibited unless specifically authorized via a case-by-case permit process. Government agencies, in addition to avoiding take, must ensure that actions they fund, authorize, or conduct are not likely to jeopardize a listed species' continued existence or adversely affect designated critical habitat. Decisions for which climate change is likely to be a key factor include: determining whether a species should be listed under the ESA, designating critical habitat areas, developing species recovery plans, and predicting whether effects of proposed human activities will be compatible with ESA-listed species' survival and recovery. Scientific analyses that underlie these critical conservation decisions include risk assessment, long-term recovery planning, defining environmental baselines, predicting distribution, and defining appropriate temporal and spatial scales. Although specific guidance is still evolving, it is clear that the unprecedented changes in global ecosystems brought about by climate change necessitate new information and approaches to conservation of imperiled species.

    Evolving changes in health care in the United States are causing new graduates and self-employed physicians to consider employment with large groups and health systems. Familiarity with the principles, proper conduct, and mechanics of negotiating an employment agreement will be important for vascular surgeons making such a decision. The various components of compensation packages and contract language need to be critically evaluated. To facilitate an understanding of the complexities involved in employment contracts, strategies to avoid making negotiating mistakes are discussed.

    2008-06-01

    Recent research has examined the effects on behavioral adjustment of a range of within-session changes in the reinforcer ratio available from two alternatives. Regularities between extended patterns of behavior (choice) and a distribution of food deliveries (expressed as a food-rate ratio) have emerged from such studies. To assess the generality of these findings, the present study manipulated rats' experience in the choice situation. Sixteen rats were divided into two groups of eight rats each. Seven non-signaled food-rate ratios were arranged to occur for responses on two concurrently available levers. Group 1 experienced a different food-rate ratio every day; each ratio provided 70 food deliveries, and none of the seven ratios operated for 2 consecutive days. Group 2 experienced the same sequence of food-rate ratios, except that each food-rate ratio remained in effect for 17 consecutive days (providing 70 food deliveries per session), after which a different food-rate ratio was selected for the next 17 sessions. In all cases, preference was adjusted to changes in food-rate ratios. Estimates of sensitivity to changes in food-rate ratios increased with an increasing number of sessions (i.e., experience in the choice situation).

    2015-01-01

    Places of work have been completely transformed by innovations in mobile work tools and ever-present access to internet data. This article characterizes use patterns and provides preliminary considerations for productive and comfortable use of common mobile devices. Two surveys described trends in mobile work. In the first, ergonomics professionals who oversee programs reported common mobile devices, their users and what data is accessed. The second, an end user survey, explored common activities performed on mobile devices, duration of use and locations where mobile work is common. The survey results provide a baseline data point for the status of mobile work in early 2014. Research indicates that additional risks have been introduced to the neck, thumbs and hands when using mobile devices. Possible trends regarding device use and work locations emerge. Intervention studies provide some direction for the practitioner. Practical strategies are outlined to reduce exposure intensity and duration. Contemporary mobile work presents tremendous change and opportunity for ergonomists and researchers to keep pace with fitting the changing models of work to the person. Continued research is needed on current mobile device use patterns to better understand ergonomic risk exposure in this rapidly changing realm.

    2016-02-01

    The two studies reported here tested whether a classroom-based psychological intervention that benefited a few African American 7th graders could trigger emergent ecological effects that benefited their entire classrooms. Multilevel analyses were conducted on data that previously documented the benefits of values affirmations on African American students' grades. The density of African American students who received the intervention in each classroom (i.e., treatment density) was used as an independent predictor of grades. Within a classroom, the greater the density of African American students who participated in the intervention exercise, the higher the grades of all classmates on average, regardless of their race or whether they participated in the intervention exercise. Benefits of treatment density were most pronounced among students with a history of poor performance. Results suggest that the benefits of psychological intervention do not end with the individual. Changed individuals can improve their social environments, and such improvements can benefit others regardless of whether they participated in the intervention. These findings have implications for understanding the emergence of ecological consequences from psychological processes.

    2012-01-01

    The French National Nutrition and Health Program was launched in 2001. To achieve its objectives, 2 main preventive strategies were identified: 1) provide information and education to help individuals make healthy food and physical activity choices; and 2) improve the food and physical environment so that making healthy choices is easier. School regulations have been established to improve the nutritional quality of meals served to children and adolescents, and vending machines have been banned. Since 2007, companies in France’s food industry have had the option of signing the national government’s “Charte d'engagement volontaire de progrès nutritionnel” (charter of commitments to nutritional improvements) which aims to benefit all consumers. A standard reference document, developed by public authorities as the basis for decisions made by a committee of experts in the food industry, aims to validate the voluntary commitments made by companies to improve the nutrient content of the foods they produce. There is strict follow-up. A Food Quality Observatory was created in 2009 to monitor the nutrient quality of the food supply in France. Various results show the positive impact of these actions.

  19. Breeding blueberries for a changing global environment: a review

    Lobos, Gustavo A.; Hancock, James F.

    2015-01-01

    Today, blueberries are recognized worldwide as one of the foremost health foods, becoming one of the crops with the highest productive and commercial projections. Over the last 100 years, the geographical area where highbush blueberries are grown has extended dramatically into hotter and drier environments. The expansion of highbush blueberry growing into warmer regions will be challenged in the future by increases in average global temperature and extreme fluctuations in temperature and rainfall patterns. Considerable genetic variability exists within the blueberry gene pool that breeders can use to meet these challenges, but traditional selection techniques can be slow and inefficient and the precise adaptations of genotypes often remain hidden. Marker assisted breeding (MAB) and phenomics could aid greatly in identifying those individuals carrying adventitious traits, increasing selection efficiency and shortening the rate of cultivar release. While phenomics have begun to be used in the breeding of grain crops in the last 10 years, their use in fruit breeding programs it is almost non-existent. PMID:26483803

    Environmental countermeasures for preventing the negative effects of global climate change and ozone depletion are discussed with special emphasis on the possibilities of space-based actions. Among the programs addressed are the Mission to Planet Earth, the Solar Power Satellite (and linkage to the Space Exploration Initiative), and proposed projects such as a lunar-based power generator that utilizes He-3 as a fusion fuel when combined with deuterium. The concept of regional working groups is proposed for initiating the programs for effective countermeasures.

    Tropical cyclones (TCs) are hazardous natural disasters. Because TC intensification is significantly controlled by atmosphere and ocean environments, changes in these environments may cause changes in TC intensity. Changes in surface and subsurface ocean conditions can both influence a TC's intensification. Regarding global warming, minimal exploration of the subsurface ocean has been undertaken. Here we investigate future subsurface ocean environment changes projected by 22 state-of-the-art climate models and suggest a suppressive effect of subsurface oceans on the intensification of future TCs. Under global warming, the subsurface vertical temperature profile can be sharpened in important TC regions, which may contribute to a stronger ocean coupling (cooling) effect during the intensification of future TCs. Regarding a TC, future subsurface ocean environments may be more suppressive than the existing subsurface ocean environments. This suppressive effect is not spatially uniform and may be weak in certain local areas.

It begins by tracing the evolving concept of the hospital, concluding that hospitals must continue to evolve in response to factors such as changing health care needs and emerging technologies. The size and distribution of hospitals are matters for ongoing debate. This paper concludes that evidence in favour of concentrating hospital facilities, whether as a means of enhancing effectiveness or efficiency, is less robust than is often assumed. Noting that care provided in hospitals is often less than satisfactory, this paper summarizes the evidence underlying three reform strategies: (i) behavioural interventions such as quality assurance programmes; (ii) changing organizational culture; and (iii) the use of financial incentives. Isolated behavioural interventions have a limited impact, but are more effective when combined. Financial incentives are blunt instruments that must be monitored. Organizational culture, which has previously received relatively little attention, appears to be an important determinant of quality of care and is threatened by ill-considered policies intended to 're-engineer' hospital services. Overall, evidence on the effectiveness of policies relating to hospitals is limited and this paper indicates where such evidence can be found. PMID:10916917

    Macrophages (Mϕs) play a critical role in the defense against pathogens, orchestrating the inflammatory response during injury and maintaining tissue homeostasis. During these processes, macrophages encounter a variety of environmental conditions that are likely to change their gene expression pattern, which modulates their function. In this study, we found that murine Mϕs displayed two different subpopulations characterized by differences in morphologies, expression of surface markers and phagocytic capacity under non-stimulated conditions. These two subpopulations could be recapitulated by changes in the culture conditions. Thus, Mϕs grown in suspension in the presence of serum were highly phagocytic, whereas subtraction of serum resulted in rapid attachment and reduced phagocytic activity. The difference in phagocytosis between these subpopulations was correlated with the expression levels of FcγR. These two cell subpopulations also differed in their responses to LPS and the expression of surface markers, including CD14, CD86, scavenger receptor A1, TLR4 and low-density lipoprotein receptor. Moreover, we found that the lipid/cholesterol content in the culture medium mediated the differences between these two cell subpopulations. Thus, we described a mechanism that modulates Mϕ function depending on the exposure to lipids within their surrounding microenvironment. PMID:26951856

  7. Plant adaptation to dynamically changing environment: the shade avoidance response.

    The success of competitive interactions between plants determines the chance of survival of individuals and eventually of whole plant species. Shade-tolerant plants have adapted their photosynthesis to function optimally under low-light conditions. These plants are therefore capable of long-term survival under a canopy shade. In contrast, shade-avoiding plants adapt their growth to perceive maximum sunlight and therefore rapidly dominate gaps in a canopy. Daylight contains roughly equal proportions of red and far-red light, but within vegetation that ratio is lowered as a result of red absorption by photosynthetic pigments. This light quality change is perceived through the phytochrome system as an unambiguous signal of the proximity of neighbors resulting in a suite of developmental responses (termed the shade avoidance response) that, when successful, result in the overgrowth of those neighbors. Shoot elongation induced by low red/far-red light may confer high relative fitness in natural dense communities. However, since elongation is often achieved at the expense of leaf and root growth, shade avoidance may lead to reduction in crop plant productivity. Over the past decade, major progresses have been achieved in the understanding of the molecular basis of shade avoidance. However, uncovering the mechanisms underpinning plant response and adaptation to changes in the ratio of red to far-red light is key to design new strategies to precise modulate shade avoidance in time and space without impairing the overall crop ability to compete for light.

    technologies. Several years ago, when many of these optical networking research topics were first being investigated, they were the subject of controversial debate. The new techniques challenged many long-held concepts related to architecture and technology. However, today all major networking organizations are transitioning toward infrastructure that incorporates these new concepts. This progress has been assisted through the series of Optical Networking Testbed Workshops (ONT). The first (ONT1) outlined a general framework of key issues and topics and developed a series of recommendations (www.nren.nasa.gov/workshop7). The second (ONT2) developed a common vision of optical network technologies, services, infrastructure, and organizations (www.nren.nasa.gov/workshop8). Processes that allow for a common vision encourage widespread deployment of these types of resources among advanced networking communities. Also, such a shared vision enables key concepts and technologies to migrate from basic research testbeds to wider networking communities. The ONT-3 workshop built on these earlier activities by expanding discussion to include additional considerations of the international interoperability and of greater impact of optical networking technology on networking in general. In accordance with this recognition, the workshop confirmed that future-oriented research and development is indispensable to fundamentally change the current Internet architecture to create a global network incorporating completely new concepts. The workshop also recognized that the first priority to allow for this progress is basic research and development, including international collaborative activities, which are important for the global realization of interoperability of a new generation architecture.

  10. Scaling Climate Change Adaptation in the Northern Great Plains through Regional Climate Summaries and Local Qualitative-quantitative Scenario Planning Workshops

    This presentation will describe a project to between ecologists and climate scientists to inform National Park Service managers who are developing scenario planning for their parks and surrounding areas; this effort is advancing scenario methodologies and improving delivery mechanisms and applications to decision-making for National Parks. Climate change is expressed in both regional climatic shifts (e.g., temperature and precipitation changes) and local resource impacts. Resource management in a changing climate is challenging because future climate change and resource responses cannot be precisely predicted. Scenario planning is a tool to assess the range of plausible future conditions. However, selecting, acquiring, synthesizing, and scaling climate information for scenario planning requires significant time and skills. This project, which was recently selected for funding by the NC CSC, has three goals: 1) synthesize climate data into 3-5 distinctly different but plausible climate summaries for the northern Great Plains region; 2) craft summaries of these climate futures that are relevant to local land management units; and 3) apply these local summaries to further develop quantitative climate-resource-management scenarios through participatory workshops and simulation models. We will engage multiple stakeholders in two focal areas within the region: southwestern South Dakota in the vicinity of Badlands National Park, and central North Dakota in the vicinity of Knife River Indian Villages National Historic Site. This effort will increase climate change planning efficiency in the region; promote collaborations across jurisdictions; and develop a prototype for a novel, efficient, and replicable form of scenario planning that could serve additional management units.

    Reports of the imminent death of the PLC (programmable logic controller) were greatly exaggerated, to paraphrase Mark Twain. In fact, the PLC is not only alive and working worldwide in thousands of applications, but it is also integrating well with related technologies. Long-term survival is a larger question - probably unanswerable given the pace of technological change. However, a few questions arise about the PLC today and in the immediate future: (1) What`s happening with programming languages? (2) Will there continue to be a {open_quotes}blurring of the lines{close_quotes} between the PLC and other technologies, and what role will software play in this integration? (3) How will the PLC`s cost and size affect the market?

    From the time of Gee's landmark writings, the recent history of celiac disease (CD) can be divided into many ages, each driven by a diagnostic advance and a deeper knowledge of disease pathogenesis. At the same time, these advances were paralleled by the identification of new clinical patterns associated with CD and by a continuous redefinition of the prevalence of the disease in population. In the beginning, CD was considered a chronic indigestion, even if the causative food was not known; later, the disease was proven to depend on an intolerance to wheat gliadin, leading to typical mucosal changes in the gut and to a malabsorption syndrome. This knowledge led to curing the disease with a gluten-free diet. After the identification of antibodies to gluten (AGA) in the serum of patients and the identification of gluten-specific lymphocytes in the mucosa, CD was described as an immune disorder, resembling a chronic "gluten infection". The use of serological testing for AGA allowed identification of the higher prevalence of this disorder, revealing atypical patterns of presentation. More recently, the characterization of autoantibodies to endomysium and to transglutaminase shifted the attention to a complex autoimmune pathogenesis and to the increased risk of developing autoimmune disorders in untreated CD. New diagnostic assays, based on molecular technologies, will introduce new changes, with the promise of better defining the spectrum of gluten reactivity and the real burden of gluten related-disorders in the population. Herein, we describe the different periods of CD experience, and further developments for the next celiac age will be proposed.

    Across the United States and around the world we are facing unprecedented demands on our surface and ground water. Increasing population demands coupled with maintaining water quality, supporting species and ecosystem services, distribution of supply, hydrologic variability associated with changing climatic conditions - all require us to look more rigorously at the intersection of policy, management and science. The water supply and hydroelectric constituencies has embraced the concept of Adaptive Management in balancing the needs of resources, people, economies and providing ecosystem support. In its infancy Adaptive Management was employed as a way to move forward on dam operation and reservoir management decisions while recognizing the unknowns of how up or downstream physical and biological elements of freshwater systems would respond. River science at the time was not mature or expansive enough to address the interrelated and complex impacts of the nuances of changing operations of dams. Adaptive Management, the concept, made good sense and has provided a framework to inform management and policy decisions while keeping the door open for integrating new knowledge into a management matrix - the essence of adaptation. The application of Adaptive Management principles has continued to expand as water management demands increase. The application and reality of the use of Adaptive Management has had variable success. In the United States we have over 25 federal agencies that have water in their mission statements. Combine this with 50 states with their own water management requirements, Native American Tribes, and countless watershed and local water supply constraints and you get a sense of the challenge associated with collaborating and addressing water management issues. Without having a set of national water objectives and goals (a National Water Policy) it is up to the collaboration and integration of the multiple water silos with appropriate science. It is

  20. Drought early warning and risk management in a changing environment

    2011-12-01

    Drought has long been recognized as falling into the category of incremental but long-term and cumulative environmental changes, also termed slow-onset or creeping events. These event types would include: air and water quality decline, desertification processes, deforestation and forest fragmentation, loss of biodiversity and habitats, and nitrogen overloading, among others. Climate scientists continue to struggle with recognizing the onset of drought and scientists and policy makers continue to debate the basis (i.e., criteria) for declaring an end to a drought. Risk-based management approaches to drought planning at the national and regional levels have been recommended repeatedly over the years but their prototyping, testing and operational implementation have been limited. This presentation will outline two avenues for disaster risk reduction in the context of drought (1) integrated early warning information systems, and (2) linking disaster risk reduction to climate change adaptation strategies. Adaptation involves not only using operational facilities and infrastructure to cope with the immediate problems but also leaving slack or reserve for coping with multiple stress problems that produce extreme impacts and surprise. Increasing the 'anticipatability' of an event, involves both monitoring of key indicators from appropriate baseline data, and observing early warning signs that assumptions in risk management plans are failing and critical transitions are occurring. Illustrative cases will be drawn from the IPCC Special Report on Managing the Risks of Extreme Events and Disasters (2011), the UN Global Assessment of Disaster Risk Reduction (2011) and implementation activities in which the author has been engaged. Most drought early warning systems have tended to focus on the development and use of physical system indicators and forecasts of trends and thresholds. We show that successful early warning systems that meet expectations of risk management also have

    Effects of acute exposure and acclimatisation to cold stress on respiratory functions were investigated in healthy tropical Indian men ( n=10). Initial baseline recordings were carried out at Delhi and thereafter serially thrice at the arctic region and once on return to Delhi. For comparison the respiratory functions were also evaluated on Russian migrants (RM; n=7) and Russian natives (RN; n=6). The respiratory functions were evaluated using standard methodology on a Vitalograph: In Indians, there was an initial decrease in lung vital capacity (VC), forced vital capacity (FVC), forced expiratory volume 1st s (FEV1), peak expiratory flow rate (PEFR) and maximum voluntary ventilation (MVV) on acute exposure to cold stress, followed by gradual recovery during acclimatisation for 4 weeks and a further significant improvement after 9 weeks of stay at the arctic region. On return to India all the parameters reached near baseline values except for MVV which remained slightly elevated. RM and RN showed similar respiratory functions at the beginning of acute cold exposure at the arctic zone. RN showed an improvement after 10 weeks of stay whereas RM did not show much change. The respiratory responses during acute cold exposure are similar to those of initial altitude responses.

    BACKGROUND: Previous isolation studies have shown increased 24-h urine volumes and body weight gains in subjects. This project examined those and other physiological variables in relationship to sleep motor activity, subjective sleep quality, mood, and complaints during confinement. METHODS: Six male and two female subjects lived for 7 d in the National Space Development Agency of Japan's isolation chamber, which simulates the interior of the Japanese Experiment Module. Each 24-h period included 6 h of sleep, 3 meals, and 20 min of exercise. Each morning, subjects completed Sleep Sensation and Complaint Index questionnaires. Catecholamine and creatinine excretion, urine volume, and body weight were measured on the 2 d before and 2 d after confinement, and sleep motor activity was measured during confinement. RESULTS: Confinement produced no significant change in body weight, urine volume, or questionnaire results. In contrast, epinephrine, norepinephrine, and sleep motor activity exhibited significant differences during confinement (p < 0.05). Higher nocturnal norepinephrine excretion correlated with higher sleep motor activity. CONCLUSION: The 24-h epinephrine values were slightly higher than normal throughout the experiment, but lower than for subjects working under time-stress. High sympathetic activity (as indicated by norepinephrine) may have interfered with sleep.

    A key limitation on the use of two-wavelength DIAL or its multi-spectral generalization is the unknown spectral structure of the topographically backscattered lidar signals in the absence of the target materials. Although some of the factors responsible for the background spectral structure can be measured in advance, others, such as the terrain differences are highly variable and usually unknown. For applications to tactical reconnainssance and high-altitude surveillance where the background is continuously changing, the inability to account for the background can seriously degrade sensor performance. This study describes a method for estimating both the spectral dependence of the background as well as the path-integrated concentration, or CL, from the same data set using dual Kalman filtering. The idea is to run parallel filters that estimate the background and CL using input from the other filter. The approach is illustrated on a variety of synthetic data sets and signal injections into background data collected by the U.S. Army WILDCAT sensor at Dugway Proving Ground.

    Corals in Maunalua Bay, Hawaii are under chronic pressures from sedimentation and terrestrial runoffs containing multiple pollutants as a result of large scale urbanization that has taken place in the last 100 years. However, some individual corals thrive despite the prolonged exposure to these environmental stressors, which suggests that these individuals may have adapted to withstand such stressors. A recent survey showed that the lobe coral Porites lobata from the `high-stress' nearshore site had an elevated level of stress ixnduced proteins, compared to those from the `low-stress,' less polluted offshore site. To understand the genetic basis for the observed differential stress responses between the nearshore and offshore P. lobata populations, an analysis of the lineage-scale population genetic structure, as well as a reciprocal transplant experiment were conducted. The result of the genetic analysis revealed a clear genetic differentiation between P. lobata from the nearshore site and the offshore site. Following the 30- day reciprocal transplant experiment, protein expression profiles and other stress-related physiological characteristics were compared between the two populations. The experimental results suggest that the nearshore genotype can cope better with sedimentation/pollutants than the offshore genotype. This indicates that the observed genetic differentiation is due to selection for tolerance to these environmental stressors. Understanding the little-known, linage-scale genetic variation in corals offers a critical insight into their short-term adaptive ability, which is indispensable for protecting corals from impending environmental and climate change. The results of this study also offer a valuable tool for resource managers to make effective decisions on coral reef conservation, such as designing marine protected areas that incorporate and maintain such genetic diversity, and establishing acceptable pollution run-off levels.

    Objective To examine longitudinal associations of the neighborhood built environment with objectively measured body mass index (BMI) and waist circumference (WC) in a geographically and racial/ethnically diverse group of adults. Design and Methods This study used data from 5,506 adult participants in the Multi-Ethnic Study of Atherosclerosis, aged 45–84 years in 2000 (baseline). BMI and WC were assessed at baseline and four follow-up visits (median follow-up 9.1 years). Time-varying built environment measures (population density, land-use, destinations, bus access, and street characteristics) were created using Geographic Information Systems. Principal components analysis was used to derive composite scores for three built environment factors. Fixed-effects models, tightly controlling for all time-invariant characteristics, estimated associations between change in the built environment and change in BMI and WC. Results Increases in the intensity of development (higher density of walking destinations and population density, and lower percent residential) were associated with less pronounced increases or decreases over time in BMI and WC. Changes in connected retail centers (higher percent retail, higher street connectivity) and public transportation (distance to bus) were not associated with changes in BMI or WC. Conclusion Longitudinal changes in the built environment, particularly increased density, are associated with decreases in BMI and WC. PMID:25136965

  19. Yeast adapts to a changing stressful environment by evolving cross-protection and anticipatory gene regulation.

    PubMed

    2013-03-01

    Organisms can protect themselves against future environmental change. An example is cross-protection, where physiological adaptation against a present environmental stressor can protect an organism against a future stressor. Another is anticipation, where an organism uses information about its present environment to trigger gene expression and other physiological changes adaptive in future environments. "Predictive" abilities like this exist in organisms that have been exposed to periodic changes in environments. It is unknown how readily they can evolve. To answer this question, we carried out laboratory evolution experiments in the yeast Saccharomyces cerevisiae. Specifically, we exposed three replicate populations of yeast to environments that varied cyclically between two stressors, salt stress and oxidative stress, every 10 generations, for a total of 300 generations. We evolved six replicate control populations in only one of these stressors for the same amount of time. We analyzed fitness changes and genome-scale expression changes in all these evolved populations. Our populations evolved asymmetric cross protection, where oxidative stress protects against salt stress but not vice versa. Gene expression data also suggest the evolution of anticipation and basal gene expression changes that occur uniquely in cyclic environments. Our study shows that highly complex physiological states that are adaptive in future environments can evolve on very short evolutionary time scales.

  20. The extent of functional redundancy changes as species’ roles shift in different environments

    2015-01-01

    Assessing the ecological impacts of environmental change requires knowledge of the relationship between biodiversity and ecosystem functioning. The exact nature of this relationship can differ considerably between ecosystems, with consequences for the efficacy of species diversity as a buffer against environmental change. Using a microbial model system, we show that the relationship can vary depending on environmental conditions. Shapes suggesting functional redundancy in one environment can change, suggesting functional differences in another environment. We find that this change is due to shifting species roles and interactions. Species that are functionally redundant in one environment may become pivotal in another. Thus, caution is advised in drawing conclusions about functional redundancy based on a single environmental situation. It also implies that species richness is important because it provides a pool of species with potentially relevant traits. These species may turn out to be essential performers or partners in new interspecific interactions after environmental change. Therefore, our results challenge the generality of functional redundancy. PMID:26578806

    This workshop is the fourth one of a series that includes the Neutrino Geophysics Conference at Honolulu, Hawaii, which I attended in 2005. This workshop was organized by the Astro-Particle and Cosmology laboratory in the recently opened Condoret building of the University of Paris. More information, including copies of the presentations, on the workshop is available on the website: www.apc.univ-paris7.fr/AAP2007/. The workshop aims at opening neutrino physics to various fields such that it can be applied in geosciences, nuclear industry (reactor and spent fuel monitoring) and non-proliferation. The workshop was attended by over 60 people from Europe, USA, Asia and Brazil. The meeting was also attended by representatives of the Comprehensive nuclear-Test Ban Treaty (CTBT) and the International Atomic Energy Agency (IAEA). The workshop also included a workshop dinner on board of a river boat sailing the Seine river.

    As a space faring nation, we are at a critical juncture in the evolution of space exploration. NASA has announced its Vision for Space Exploration, a vision of returning humans to the Moon, sending robots and eventually humans to Mars, and exploring the outer solar system via automated spacecraft. However, mission concepts have become increasingly complex, with the potential to yield a wealth of scientific knowledge. Meanwhile, there are significant resource challenges to be met. Launch costs remain a barrier to routine space flight; the ever-changing fiscal and political environments can wreak havoc on mission planning; and technologies are constantly improving, and systems that were state of the art when a program began can quickly become outmoded before a mission is even launched. This Conference Publication describes the workshop and featured presentations by world-class experts presenting leading-edge technologies and applications in the areas of power and propulsion; communications; automation, robotics, computing, and intelligent systems; and transformational techniques for space activities. Workshops such as this one provide an excellent medium for capturing the broadest possible array of insights and expertise, learning from researchers in universities, national laboratories, NASA field Centers, and industry to help better our future in space.

    Simulated teaching methods enable a safe learning environment that are structured, constructive and reflective. We prepared a 2-day simulation project to help prepare students for their first clinical practice. A quasi-experimental pre-test - post-test design was conducted. Qualitative data from the open-ended survey questions were analysed using content analysis. Confidence intervals and p-values were calculated to demonstrate the changes in participants' levels of understanding/ability or confidence in clinical midwifery skills included in the simulation. 71 midwifery students participated. Students rated their understanding, confidence, and abilities as higher after the simulation workshop, and higher still after their clinical experience. There were five main themes arising from the qualitative data: having a learning experience, building confidence, identifying learning needs, developing communication skills and putting skills into practise. First year midwifery students felt well prepared for the clinical workplace following the simulation workshops. Self-rated understanding, confidence and abilities in clinical midwifery skills were significantly higher following consolidation during clinical placement. Longitudinal studies on the relationship between simulation activities and student's overall clinical experience, their intentions to remain in midwifery, and facility feedback, would be desirable.

  4. Photosynthesis, environmental change, and plant adaptation: Research topics in plant molecular ecology. Summary report of a workshop

    1995-07-01

    As we approach the 21st Century, it is becoming increasingly clear that human activities, primarily related to energy extraction and use, will lead to marked environmental changes at the local, regional, and global levels. The realized and the potential photosynthetic performance of plants is determined by a combination of intrinsic genetic information and extrinsic environmental factors, especially climate. It is essential that the effects of environmental changes on the photosynthetic competence of individual species, communities, and ecosystems be accurately assessed. From October 24 to 26, 1993, a group of scientists specializing in various aspects of plant science met to discuss how our predictive capabilities could be improved by developing a more rational, mechanistic approach to relating photosynthetic processes to environmental factors. A consensus emerged that achieving this goal requires multidisciplinary research efforts that combine tools and techniques of genetics, molecular biology, biophysics, biochemistry, and physiology to understand the principles, mechanisms, and limitations of evolutional adaptation and physiological acclimation of photosynthetic processes. Many of these basic tools and techniques, often developed in other fields of science, already are available but have not been applied in a coherent, coordinated fashion to ecological research. The efforts of this research program are related to the broader efforts to develop more realistic prognostic models to forecast climate change that include photosynthetic responses and feedbacks at the regional and ecosystem levels.

    We use 31 boreholes to reconstruct the depositional environments in the southwestern Taiwan. Based on the sedimentary structures, it is divided into eight facies associations that is important to reconstruct depositional environment. Based on the depositional environment, sequence stratigraphy and radiocarbon dating data, it can be implied significant environment and shoreline changes. (1) The southwestern Taiwan is characterized by a subaerial environment and formed two incised valleys during the sea-level fall in the last glacial maximum epoch. (2) The shoreline was migrated to the landward and close to the frontal foothills, and the environment changed deepen into tidal flat and lagoon during 18,000-10,000 years ago. (3) The area occurred the deepest environment from shoreface to offshore transition during 8,000-7,000 years ago. (4) The shoreline was retreated to the seaward. The environment changed shallowen into barrier island, lagoon, and coastal plain since 7,000 years ago. This study confirm the decreasing accommodation space in this area result from huge sediment inputs and decreased eustatic sea-level rise, which cause the maximum flooding epoch appear earlier.

    Increased concern over the effects of global climate change and depletion of the ozone layer has resulted in support for the Global Change Research Program and the Mission to Planet Earth. Research to understand Earth system processes is critical, but it falls short of providing ways of mitigating the effects of change. Geoengineering options and alternatives to interactively manage change need to be developed. Space-based concepts for dealing with changes to the environment should be considered in addition to Earth-based actions. 'Mission for Planet Earth' describes those space-based geoengineering solutions that may combine with an international global change program to stabilize the Global environment. Large space systems that may be needed for this response challenge guidance and control engineering and technology. Definition, analysis, demonstration, and preparation of geoengineering technology will provide a basis for policy response if global change consequences are severe.

    Evaluation of a new systems-based curriculum in an undergraduate Irish Medical School was carried out with the validated Dundee Ready Educational Environment (DREEM) inventory. Comparison was made with the results from a previous DREEM study in the old curriculum. DREEM was administered to 225 medical students enrolled in the new curriculum. Data analysis was carried out using SPSS 17.0 and the Student unpaired t test. Increased mean scores supported greater satisfaction with the educational environment in the new curriculum. Students perceived better opportunities to develop interpersonal skills, ask questions and learn about empathy. Areas of concern included timetabling, support for stressed students and provision of feedback. Clinical students perceived their overall environment more positively. Pre-clinical students were more confident about passing exams and felt better prepared for clinical practice. Male students were more positive about the environment and found the teaching more stimulating. Female students perceived greater development of their problem-solving skills. Non-Irish students no longer perceived the atmosphere and their social self-perceptions more negative than Irish students, as was the case in the old curriculum. DREEM is a valuable tool in evaluating the educational environment and monitoring the impact of curricular change.

  13. Obesity and the built environment: changes in environmental cues cause energy imbalances.

    PubMed

    Cohen, D A

    2008-12-01

    The past 30 years have seen dramatic changes in the food and physical activity environments, both of which contribute to the changes in human behavior that could explain obesity. This paper reviews documented changes in the food environment, changes in the physical activity environment and the mechanisms through which people respond to these environments, often without conscious awareness or control. The most important environmental changes have been increases in food accessibility, food salience and decreases in the cost of food. The increases in food marketing and advertising create food cues that artificially stimulate people to feel hungry. The existence of a metabolic pathway that allows excess energy to be stored as fat suggests that people were designed to overeat. Many internal mechanisms favor neurophysiologic responses to food cues that result in overconsumption. External cues, such as food abundance, food variety and food novelty, cause people to override internal signals of satiety. Other factors, such as conditioning and priming, tie food to other desirable outcomes, and thus increase the frequency that hunger is stimulated by environmental cues. People's natural response to the environmental cues are colored by framing, and judgments are flawed and biased depending on how information is presented. People lack insight into how the food environment affects them, and subsequently are unable to change the factors that are responsible for excessive energy consumption. Understanding the causal pathway for overconsumption will be necessary to interrupt the mechanisms that lead to obesity.

  14. Dynamics of evolutionary rescue in changing environments and the emergence of antibiotic resistance.

    2014-01-07

    Populations can go extinct when their environments deteriorate, but evolutionary rescue occurs when a shrinking population adapts to the new environmental conditions. The emergence of resistance from a drug sensitive bacterial population under treatment can be regarded as an instance of evolutionary rescue. Understanding evolutionary rescue in a particular context such as drug resistance requires knowledge of how the environment changes and how selection coefficients change as a result. In this study, we propose a model for evolutionary rescue under three different scenarios of environmental change: abrupt change, periodic fluctuation and gradual decay. The model makes use of the notion of reaction norms to describe fitness values that depend on both genotype and environmental state. We find that although drug sensitive bacterial populations may be large, allowing them to generate resistant mutants frequently, a harsh abrupt change due to the drug usually drives them extinct. Evolutionary rescue occurs far more frequently under the milder forms of environmental change we investigated. Rescue is favoured when the absolute fitnesses of individuals remain sufficiently high over the range of environment qualities experienced by the population. The minimum environment quality, which is inversely related to drug dose in the antibiotic context, is thus an important factor. Interestingly, in the periodic fluctuation model, the inter-dose period is less influential in promoting rescue through resistance unless the minimum environment quality is in a particular range. We also investigated fitness trade-offs across environments including the case of a resistant allele not subject to any trade-off (a "superbug"). This fitness trade-off affects the probability of rescue in decaying environments, but surprisingly has only a weak effect in the periodic fluctuation scenario. Finally, we use the model to show how niche construction, whereby organisms are the source of environmental

    NASA Astrophysics Data System (ADS)

    Chipperfield, Alan

    ADAM is now a major software project; it provides a fully integrated environment for both data reduction and data acquisition. It is being used in Hawaii, Australia and the Canary Islands, as well as the UK, and has been adopted by Starlink as the environment in which Starlink data reduction software should run. One of the most remarkable things about ADAM is that it has been developed as a co-operative effort between groups that are spread across the world. Although the initial system came out of RGO, and ROE provided by far the major effort in designing and implementing the VAX version, various parts of what is now regarded as 'ADAM' have also come from other establishments. Co-ordinating a project being developed in this way is not an easy job, but the somewhat varied parentage of ADAM - although sometimes an administrative nightmare - is also one of its strengths; it is not a system developed in one place to serve the specific needs of that one place. One way in which this development is co-ordinated is by a series of workshops. These have taken place at about 18 month intervals since the first one in late 1985. The workshops are attended by people actively developing and/or making extensive use of ADAM, and provide a forum for detailed discussion of the problems in the current system and plans for its extension. The 1989 ADAM Workshop was held at Cosener's House, Abingdon from 3rd to 7th July 1989. An 'Open Meeting' was held on Friday 30th June at RAL to enable members of the Starlink community to provide input to the Workshop discussions. Before the previous workshop, in Hawaii, a trend had started to emerge for different establishments to plug the gaps in ADAM (which at the time was missing a number of important facilities) with local solutions. The Hawaii Workshop consolidated these local extensions, adopting some and rejecting others. As a result, ADAM, as reviewed by this third workshop, was a much more complete and uniform system, and it was possible to

    Mars Telescopic Observations Workshop E convened in Tucson, Arizona, in October 1997 by popular demand slightly over two years following the first successful Mars Telescopic Observations Workshop, held in Ithaca, New York, in August 1995. Experts on Mars from the United Kingdom, Japan, Germany, and the United States were present. Twenty-eight oral presentations were made and generous time allotted for useful discussions among participants. The goals of the workshop were to (1) summarize active groundbased observing programs and evaluate them in the context of current and future space missions to Mars, (2) discuss new technologies and instrumentation in the context of changing emphasis of observations and theory useful for groundbased observing, and (3) more fully understand capabilities of current and planned Mars missions to better judge which groundbased observations are and will continue to be of importance to our overall Mars program. In addition, the exciting new discoveries presented from the Pathfinder experiments and the progress report from the Mars Global Surveyor infused the participants with satisfaction for the successes achieved in the early stages of these missions. Just as exciting was the enthusiasm for new groundbased programs designed to address new challenges resulting from mission science results. We would like to thank the National Aeronautics and Space Administration as well as Dr. David Black, director of the Lunar and Planetary Institute, and the staff of the Institute's Publications and Program Services Department for providing logistical, administrative, and publication support services for this workshop.

  2. Complex Genotype by Environment interactions and changing genetic architectures across thermal environments in the Australian field cricket, Teleogryllus oceanicus

    PubMed Central

    2011-01-01

    Background Biologists studying adaptation under sexual selection have spent considerable effort assessing the relative importance of two groups of models, which hinge on the idea that females gain indirect benefits via mate discrimination. These are the good genes and genetic compatibility models. Quantitative genetic studies have advanced our understanding of these models by enabling assessment of whether the genetic architectures underlying focal phenotypes are congruent with either model. In this context, good genes models require underlying additive genetic variance, while compatibility models require non-additive variance. Currently, we know very little about how the expression of genotypes comprised of distinct parental haplotypes, or how levels and types of genetic variance underlying key phenotypes, change across environments. Such knowledge is important, however, because genotype-environment interactions can have major implications on the potential for evolutionary responses to selection. Results We used a full diallel breeding design to screen for complex genotype-environment interactions, and genetic architectures underlying key morphological traits, across two thermal environments (the lab standard 27°C, and the cooler 23°C) in the Australian field cricket, Teleogryllus oceanicus. In males, complex three-way interactions between sire and dam parental haplotypes and the rearing environment accounted for up to 23 per cent of the scaled phenotypic variance in the traits we measured (body mass, pronotum width and testes mass), and each trait harboured significant additive genetic variance in the standard temperature (27°C) only. In females, these three-way interactions were less important, with interactions between the paternal haplotype and rearing environment accounting for about ten per cent of the phenotypic variance (in body mass, pronotum width and ovary mass). Of the female traits measured, only ovary mass for crickets reared at the cooler

  6. Dousing our inflammatory environment(s): is personal carbon trading an option for reducing obesity--and climate change?

    PubMed

    Egger, G

    2008-09-01

    Obesity and climate change are two problems currently challenging humanity. Although apparently unrelated, an epidemiological approach to both shows a similar environmental aetiology, based in modern human lifestyles and their driving economic forces. One way of analysing this is through inflammation (defined as '. . . a disturbance of function following insult or injury') of both the internal (biological) and external (ecological) environments. Chronic, low-grade, systemic inflammation has recently been shown to accompany obesity, as well as a range of biological pathologies associated with obesity (diabetes, heart disease, some cancers, etc.). This is influenced by the body's inability to soak up excess glucose as a result of insulin resistance. In a broader sense, inflammation is a metaphor for ecological 'pathologies', manifest particularly in unnatural disturbances like climate change, ocean acidity, rising temperatures and species extinction, associated with the inability of the world's environmental 'sinks' to soak up carbon dioxide ('carbon resistance'?). The use of such a metaphorical analysis opens the possibilities for dealing with two interdisciplinary problems simultaneously. Strategies for managing climate change, including personal carbon trading, could provide a 'stealth intervention' for reducing population levels of obesity by increasing personal energy expenditure and decreasing energy-dense food intake, as well as reducing the carbon emissions causing climate change.

    Fisheries collapse in the Pacific Northwest. Fisheries resurge in Alaska. Such headlines reflect changes in the Pacific biosphere, occurring at all trophic levels from plankton through seabirds and at all scales from a few kilometers of patchiness to nearly synchronous changes across distances of 10,000 km. Are the large-scale, Pacific-wide changes in the biosphere a response to changes in the physical ocean environment, itself linked to large-scale, ocean-atmosphere changes? Plankton biologists, fisheries researchers, marine mammals and birds specialists, physical oceanographers, statisticians, and climate dynamicists tackled this question at the 10th [Aha Huliko]a Hawaiian Winter Workshop.

    Expression variation plays an important role in plant adaptation, but little is known about the factors impacting the expression variation when population adapts to changing environment. We used RNA-seq data from 80 individuals in 14 Miscanthus lutarioriparius populations, which were transplanted into a harsh environment from native habitat, to investigate the expression level, expression diversity and genetic diversity for genes expressed in both environments. The expression level of genes with lower expression level or without SNP tended to be more changeable in new environment, which suggested highly expressed genes experienced stronger purifying selection than those at lower level. Low proportion of genes with population effect confirmed the weak population structure and frequent gene flow in these populations. Meanwhile, the number of genes with environment effect was the most frequent compared with that with population effect. Our results showed that environment and genetic diversity were the main factors determining gene expression variation in population. This study could facilitate understanding the mechanisms of global gene expression variation when plant population adapts to changing environment. PMID:27150248

    A workshop to discuss recent pressing problems experienced in the operation of helium refrigerators at the national laboratories was proposed by DOE. Early in 1980 it was decided that the workshop should be held at the Fermi National Accelerator Laboratory (Fermilab). The reasoning behind the selection of Fermilab included the proposed initial tests of the Central Liquefier, the recently experienced problems with refrigeration systems at Fermilab, and the fact that a previous workshop had been held at the Brookhaven National Laboratory, which, at present, would be the other logical choice for the workshop.

    The workshop was organized to focus on a specific confinement scheme: the tokamak. The workshop was divided into two parts: systems and physics. The topics discussed in the systems session were narrowly focused on systems and engineering considerations in the tokamak geometry. The workshop participants reviewed the status of system studies, trade-offs between d-t and d-d based reactors and engineering problems associated with the design of a high-temperature, high-field reactor utilizing advanced fuels. In the physics session issues were discussed dealing with high-beta stability, synchrotron losses and transport in alternate fuel systems. The agenda for the workshop is attached.

  18. Reinforcement learning and counterfactual reasoning explain adaptive behavior in a changing environment.

    Animals routinely adapt to changes in the environment in order to survive. Though reinforcement learning may play a role in such adaptation, it is not clear that it is the only mechanism involved, as it is not well suited to producing rapid, relatively immediate changes in strategies in response to environmental changes. This research proposes that counterfactual reasoning might be an additional mechanism that facilitates change detection. An experiment is conducted in which a task state changes over time and the participants had to detect the changes in order to perform well and gain monetary rewards. A cognitive model is constructed that incorporates reinforcement learning with counterfactual reasoning to help quickly adjust the utility of task strategies in response to changes. The results show that the model can accurately explain human data and that counterfactual reasoning is key to reproducing the various effects observed in this change detection paradigm.

    People who apply to participate in this workshop appear to be genuinely interested in personal development. Participants reported that they were not very happy with several aspects of their jobs prior to the workshop. Predominant personality characteristics of the participants were shyness, communication anxiety, reserved style, cautiousness, moodiness, energetic, hard-working and analytical minded. Participants were favorably impressed with the workshop. One of the most potent ways that the workshop impacts participants is through improved self understanding and enhanced self-esteem. Many people did change jobs following the workshop. Of those who did not actually change jobs, almost half reported that they had modified their present job to achieve a better person-job fit. Participants did not report many changes in their routine behavior although they kept the supervisor more informed of their job activity. Current job satisfaction is good among the participants. Although the workshop is fairly expensive to provide, the long range benefits in terms of enhanced levels of performance far outweigh the costs.

    The specific aim for this pilot study was to evaluate the effectiveness of a nutrition and media literacy intervention targeting elementary students and their parents. The purpose of the intervention was to increase child fruit and vegetables (FV) consumption and change the home nutrition environment (measured with FV availability and accessibility and parental social support). During the intervention, students learned about nutrition, the role media plays in shaping values concerning nutrition, and developed a media campaign for their parents. A quasi-experimental research design was used to evaluate the effectiveness of the intervention. The media intervention was effective in changing the home environment.

    The objective of the study was to determine which age-related changes in sensation and cognition are associated with age-related changes in the ability to monitor the environment. To that end, a proxy measure of the ability to monitor the environment (useful field of view, UFOV) and measures of sensation and cognition were collected from young adult (N = 61) and older adult subjects (N = 79). Although UFOV performance was expected to be mediated primarily by cognition rather than by sensation, it was somewhat unexpected to find no reliable associations between UFOV and sensory functioning beyond those of age and cognition.

    Since their introduction into clinical trials in the United States, endovascular aortic grafts have shown various types of problems. Although details of design and construction vary between different endovascular grafts and failure modes have had a variety of causes and clinical effects, the inability of preclinical testing to predict these failures remains common to all endovascular grafts. The need to improve preclinical testing in an attempt to reduce clinical device failures resulted in a Food and Drug Administration-sponsored workshop on endovascular graft preclinical testing held in Rockville, Md, from July 31 to August 1, 2001. FORMAT: The workshop was not designed as a consensus conference. Instead, it provided a forum for bringing stakeholders together to define problems and identify areas of agreement and disagreement. The workshop had 34 invited participants who represented device manufacturers, the medical community, the Food and Drug Administration, and testing facilities, and international attendance was more than 120 people. Discussion centered on: 1, defining the physiologic, anatomic, and morphologic characteristics of abdominal aortic aneurysms before and after endovascular graft treatment; 2, identifying the types of failures that have been observed clinically; and 3, determining which characteristics should be considered during preclinical modeling to better predict clinical performance. Attendees agreed to the need to better define and address anatomic characteristics and changes in the aneurysm after endograft treatment to optimize preclinical testing. Much discussion and little agreement occurred on the importance of flow-related forces on graft performance or the need or ability to define and model physiologic compliance during durability testing. The discussion and conclusions are summarized in this paper and are provided in detail at: http://www.fda.gov/cdrh/meetings/073101workshop.html. The workshop raised awareness of significant

    vendor technical or business problems. HPC, by its very nature, is an exercise in multi-level risk management. Every aspect of stewarding HPCCs into the petascale era, from identification of the program drivers to the details of procurement actions and simulation environment component deployments, represents unprecedented challenges and requires effective risk management. The fundamental purpose of this workshop was to go beyond risk management processes as such and learn how to weave effective risk management practices, techniques, and methods into all aspects of migrating HPCCs into the next generation of leadership computing systems. This workshop was a follow-on to the Petascale System Integration Workshop hosted by Lawrence Berkeley National Laboratory (LBNL)/NERSC last year. It was intended to leverage and extend the risk management experience of the participants by looking for common best practices and unique processes that have been especially successful. This workshop assessed the effectiveness of tools and techniques that are or could be helpful in HPCC risk management, with a special emphasis on how practice meets process. As the saying goes: 'In theory, there is no difference between theory and practice. In practice there is'. Finally, the workshop brought together a network of experts who shared information as technology moves into the petascale era and beyond.

  4. Changing surgical education strategies in an environment of changing health care delivery systems.

    Dunnington, G L; DaRosa, D A

    1994-01-01

    Emerging changes in health care delivery will have a significant impact on the structure of surgical education in academic departments of surgery. Based on some assumptions as to the probable nature of the final product of this reform, this article encourages a proactive stance by surgical educators to anticipate changes and move toward restructuring in areas of curricular content, the teaching process, performance evaluation strategies, and faculty infrastructure of the academic department. Curriculum changes must bridge the gap between public health and medicine and continue the aggressive trend toward teaching in the outpatient setting. Surgical educators must adapt to evolving computer and instructional technology that will make multimedia presentations, distance education, teleconferencing, hypermedia, and virtual reality commonplace in the teaching setting. Increased emphasis on accountability and accreditation will require stringent criteria in performance and program evaluation methodology. The academic infrastructure will need to adapt to the changing goal of training more general surgeons and fewer specialists and yet maintain the fundamental responsibility of an academic surgeon for mentoring the medical student and surgical resident.

  6. Does change in the neighborhood environment prevent obesity in older women?

    Neighborhood environment is consistently associated with obesity; changes to modifiable aspects of the neighborhood environment may curb the growth of obesity in the US and other developed nations. However, currently the majority of studies are cross-sectional and thus not appropriate for evaluating causality. The goal of this study was to evaluate the effect of a neighborhood-changing intervention on changes in obesity among older women. Over the past 30 years the Portland, Oregon metropolitan region has made significant investments in plans, regulatory structures, and public facilities to reduce sprawl and increase compact growth centers, transit-oriented development approaches, and green space. We used geocoded residential addresses to link data on land-use mix, public transit access, street connectivity, and access to green space from four time points between 1986–2004, with longitudinal data on body mass index (BMI) from a cohort of 2,003 community-dwelling women aged 66 years and older. Height and weight were measured at clinic visits. Women self-reported demographics, health habits, and chronic conditions, and self-rated their health. Neighborhood socioeconomic status was assessed from census data. Neighborhood walkability and access to green space improved over the 18-year study period. On average there was a non-significant mean weight loss in the cohort between baseline (mean age 72.6 years) and the study’s end (mean age 85.0 years). We observed no association between neighborhood built environment or change in built environment and BMI. Greater neighborhood socioeconomic status at baseline was independently associated with a healthier BMI at baseline, and protected against an age-related decline in BMI over time. BMI decreases with age reflect increased frailty, especially among older adults with complex morbidities. Future research should consider the influence of the neighborhood environment on additional relevant health outcomes and should include

  7. Molecular and cellular bases of adaptation to a changing environment in microorganisms

    Environmental heterogeneity constitutes an evolutionary challenge for organisms. While evolutionary dynamics under variable conditions has been explored for decades, we still know relatively little about the cellular and molecular mechanisms involved. It is of paramount importance to examine these molecular bases because they may play an important role in shaping the course of evolution. In this review, we examine the diversity of adaptive mechanisms in the face of environmental changes. We exploit the recent literature on microbial systems because those have benefited the most from the recent emergence of genetic engineering and experimental evolution followed by genome sequencing. We identify four emerging trends: (i) an adaptive molecular change in a pathway often results in fitness trade-off in alternative environments but the effects are dependent on a mutation's genetic background; (ii) adaptive changes often modify transcriptional and signalling pathways; (iii) several adaptive changes may occur within the same molecular pathway but be associated with pleiotropy of different signs across environments; (iv) because of their large associated costs, macromolecular changes such as gene amplification and aneuploidy may be a rapid mechanism of adaptation in the short-term only. The course of adaptation in a variable environment, therefore, depends on the complexity of the environment but also on the molecular relationships among the genes involved and between the genes and the phenotypes under selection.

    Abstract (2,250 Maximum Characters): The Astronomy Workshop (http://janus.astro.umd.edu) is a collection of interactive online educational tools developed for use by students, educators, professional astronomers, and the general public. The more than 20 tools in the Astronomy Workshop are rated for ease-of-use, and have been extensively tested in large university survey courses as well as more specialized classes for undergraduate majors and graduate students. Here we briefly describe the tools most relevant for the Professional Dynamical Astronomer. Solar Systems Visualizer: The orbital motions of planets, moons, and asteroids in the Solar System as well as many of the planets in exoplanetary systems are animated at their correct relative speeds in accurate to-scale drawings. Zoom in from the chaotic outer satellite systems of the giant planets all the way to their innermost ring systems. Orbital Integrators: Determine the orbital evolution of your initial conditions for a number of different scenarios including motions subject to general central forces, the classic three-body problem, and satellites of planets and exoplanets. Zero velocity curves are calculated and automatically included on relevant plots. Orbital Elements: Convert quickly and easily between state vectors and orbital elements with Changing the Elements. Use other routines to visualize your three-dimensional orbit and to convert between the different commonly used sets of orbital elements including the true, mean, and eccentric anomalies. Solar System Calculators: These tools calculate a user-defined mathematical expression simultaneously for all of the Solar System's planets (Planetary Calculator) or moons (Satellite Calculator). Key physical and orbital data are automatically accessed as needed.

    Three ecology-meteorology workshops were held at the University of Michigan Biological Station in summers 1975, 1976, and 1977. The purpose of the workshops was to identify and focus attention on the common areas of research that require the cooperative efforts of ecologists and meteorologists. It was felt that these two respected groups of scientists have been quite isolated from each other, each underestimating the contribution and complexity of the other discipline. Yet the complex environments they investigate are strikingly interactive. To fully understand these relationships, it was intended to promote more communication between the two disciplines through the format of workshops in a secluded environment free from outside distractions conductive to easy communication.
