    1988-01-01

    Space power sources are becoming a central focus for determining man's potential and schedule for exploring and utilizing the benefits of space. The ability to search, probe, survey, and communicate throughout the universe will depend on providing adequate power to the instruments to do these jobs. Power requirements for space platforms are increasing and will continue to increase into the 21st century. Photovoltaics have been a dependable power source for space for the last 30 years and have served as the primary source of power on virtually all DOD and NASA satellites. The performance of silicon (Si) solar cells has increased from 10 percent air mass zero (AM0) solar energy conversion efficiency in the early 60's to almost 15 percent on today's spacecraft. Some technologists even think that the potential for solar photovoltaics has reached a plateau. However, present and near-future Air Force and NASA requirements show needs that, if the problems are looked upon as opportunities, can elevate the photovoltaic power source scientist and array structure engineer into the next technological photovoltaic growth curve.

    Berry, Jan; Griffin, Mr. Bob; Wright, Anthony L

    2006-01-01

    Steam pressure reduction has the potential to reduce fuel consumption for a minimum capital investment. When the pressure at the boiler is reduced, fuel and steam are saved as a result of changes in the high-pressure side of the steam system from the boiler through the condensate return system. In the boiler plant, losses from combustion, boiler blowdown, radiation, and steam venting from condensate receivers would be reduced by reducing steam pressure. Similarly, in the steam distribution system, losses from radiation, flash steam vented from condensate receivers, and component and steam trap leakage would also be reduced. There are potential problems associated with steam pressure reduction, however. These may include increased boiler carryover, boiler water circulation problems in watertube boilers, increased steam velocity in piping, loss of power in steam turbines, and issues with pressure reducing valves. This paper is based a Steam Technical Brief sponsored by the U.S. Department of Energy (DOE) Office of Energy Efficiency and Renewable Energy and Enbridge Gas Distribution, Inc. (5). An example illustrates the use of DOE BestPractices Steam System Assessment Tool to model changes in steam, fuel, electricity generation, and makeup water and to estimate resulting economic benefits.

  10. Evaluating Broader Impacts: Issues and Opportunities (Invited)

    2010-12-01

    The NSF expects that funded projects will include activities that have intrinsic Intellectual Merit and that promote the Broader Impacts (BI) of this work to those outside the immediate research community. These BI activities take many forms, but often involve collaborations with schools, informal science centers, and media developers in efforts to promote the public understanding of science, encourage a talented and diverse pool of students to pursue careers in science, and illustrate the benefits society derives from scientific discoveries. A critical question is how to evaluate individual BI activities and the overall portfolio of BI activities. What are the metrics for success? How can evaluation results be used to improve the BI portfolio? Evaluation of BI activities is complicated by several factors, including: [1] The scope of BI activities is highly variable across different types of NSF-funded projects. Individual research projects typically have limited BI activities, with only modest funding (<10%) designated for these efforts, and evaluation efforts are rare. On the other hand, large projects such as research centers and major facilities typically have dedicated BI/education specialists and formal evaluation expertise. An additional complication is that many BI activities are unique or have novel aspects that reflect the local circumstances and opportunities, but make it difficult to develop broadly-applicable evaluation instruments;[2] There is not consensus on the perspective from which the evaluation should be conducted. Scientists, participants (teachers, students, museum/aquarium personnel), and the funding agencies typically have differing objectives and metrics for BI projects. [3] The timeframe for conducting any evaluation is frequently limited to a few years, placing limitations on the scope of the evaluation effort. Long-term learning, career impacts, and changes in cultural attitudes or perceptions are difficult to assess under this

    Food Stamp Nutrition Education (FSNE) is an optional component of the Food Stamp Program aimed at improving food choices of program participants. The last decade has seen a dramatic expansion in FSNE, accompanied by increased interest in FSNE evaluation. The Society for Nutrition Education, as a leader in nutrition education research, has worked collaboratively with federal partners to improve FSNE evaluation. This is the first in a 3-part series of papers presented in this issue of the Journal of Nutrition Education and Behavior. The series reviews the issues, priority needs, and opportunities identified through this process; explains our current focus on the development of a brief measure assessing FSNE-relevant dietary behaviors; and describes plans for measurement development.

  12. The geologist and public policy issues, opportunities and obligations

    SciTech Connect

    Schmidt, W. )

    1993-03-01

    Historically, geologists have been perceived by the public as solely involved in resource exploration and production or geologic hazards mitigation. This generally included mining, oil drilling, landslide or earthquake (after the fact) comments, and rock or mineral collecting. These operations have come to be associated with land exploitation involving extraction of non-renewable resources, and often, in consequence, pollution. These generic activities may not currently be considered environmentally sound or politically correct. Because of the high visibility of environmental issues in recent years, geologists now have an opportunity to offer necessary input contributing to solutions for many of these problems. Indeed, geologists must be thought of as part of the solution, and thus alter public perception that geologists are facilitators of environmental damage. After all, who may better protect and conserve the earth and its environments than people trained in the Earth Sciences Governmental and industry or consulting geologists are now involved in a wide range of interpretative geologic decisions regarding a cross-section of activities aimed at development and conservation of lands and natural resources. These can be grouped in generalized categories including: waste disposal issues, water resources issues, land-use planning and zoning issues, and resource conservation or regulation requirements.

  13. The Data Issue: Opportunities and Challenges for Scientific Publishers

    2011-12-01

    Using the recent report for the 'Opportunities in Data Exchange' Project produced by - and for - researchers, libraries/data centres and publishers (and which is based on a broad range of studies, questionnaires and evidence) we have defined current practices and expectations, and the gaps and dilemmas involved in producing data and datasets, and then analysed their relationship to formal publications. As a result, we identified potential opportunities to evolve scientific insights to be more useful and re-useful: with consequent implications for custodianship and long-term data management. We also defined a number of key incentives and barriers towards achieving these objectives. As a case study, the earth and environmental sciences have come under particularly close scrutiny with respect to data-ownership and -sharing arrangements, sometimes with damaging results to the discipline's reputation. These issues, along with considerable technological challenges, have to be handled effectively in order to best support all the users along the data chain. To that end, we show that key stakeholders - among them scientific publishers - need to have a clear idea of how to progress data-intensive derived information, which we demonstrate is often not the case. Towards bridging this knowledge gap, we have compiled a roadmap of next steps and key issues to be acknowledged and addressed by the scientific publishing community. These include: engaging directly with researchers, policy-makers, funding bodies and direct competitors to build innovative partnerships and enhance impact; providing technological and training investment and developing alongside the emerging discipline of 'data scientist': the 'data publisher'. This individual/company will need to combine a close understanding of researchers' priorities, together with market, legal and technical opportunities and restrictions.

    2011-12-01

    Two-year colleges (2YCs) play a critical role in geoscience education in the United States. Nearly half of the undergraduate students who take introductory geoscience do so at a 2YC. With awide reach and diverse student populations, 2YCs may be key to producing a well-trained, diverse and sufficiently large geoscience workforce. However, faculty at 2YCs often face many barriers to professional development including lack of financial resources, heavy and inflexible teaching loads, lack of awareness of opportunities, and few professional development resources/events targeted at their needs. As an example, at the 2009 GSA meeting in Portland, fewer than 80 of the 6500 attendees were from community colleges, although this was more than twice the 2YC faculty attendance the previous year. Other issues include the isolation described by many 2YC geoscience faculty who may be the only full time geoscientist on a campus and challenges faced by adjunct faculty who may have even fewer opportunities for professional development and networking with other geoscience faculty. Over the past three years we have convened several workshops and events for 2YC geoscience faculty including technical sessions and a workshop on funding opportunities for 2YC faculty at GSA annual meetings, a field trip and networking event at the fall AGU meeting, a planning workshop that examined the role of 2YCs in geoscience education and in broadening participation in the geosciences, two workshops supporting use of the 'Math You Need, When You Need It' educational materials that included a majority of 2YC faculty, and marine science summer institutes offered by COSEE-Pacific Partnerships for 2YC faculty. Our experience indicates that 2YC faculty desire professional development opportunities when the experience is tailored to the needs and character of their students, programs, and institutions. The content of the professional development opportunity must be useful to 2YC faculty -workshops and

  15. Virtual Environments: Issues and Opportunities for Researching Inclusive Educational Practices

    NASA Astrophysics Data System (ADS)

    Sheehy, Kieron

    This chapter argues that virtual environments offer new research areas for those concerned with inclusive education. Further, it proposes that they also present opportunities for developing increasingly inclusive research processes. This chapter considers how researchers might approach researching some of these affordances. It discusses the relationship between specific features of inclusive pedagogy, derived from an international systematic literature review, and the affordances of different forms of virtual characters and environments. Examples are drawn from research in Second LifeTM (SL), virtual tutors and augmented reality. In doing this, the chapter challenges a simplistic notion of isolated physical and virtual worlds and, in the context of inclusion, between the practice of research and the research topic itself. There are a growing number of virtual worlds in which identified educational activities are taking place, or whose activities are being noted for their educational merit. These encompasses non-themed worlds such as SL and Active Worlds, game based worlds such as World of Warcraft and Runescape, and even Club Penguin, a themed virtual where younger players interact through a variety of Penguin themed environments and activities. It has been argued that these spaces, outside traditional education, are able to offer pedagogical insights (Twining 2009) i.e. that these global virtual communities have been identified as being useful as creative educational environments (Delwiche 2006; Sheehy 2009). This chapter will explore how researchers might use these spaces to investigative and create inclusive educational experiences for learners. In order to do this the chapter considers three interrelated issues: What is inclusive education?; How might inclusive education influence virtual world research? And, what might inclusive education look like in virtual worlds?

  16. Issues in electric power in India: Challenges and opportunities

    NASA Astrophysics Data System (ADS)

    Tongia, Rahul

    This dissertation provides an examination of three facets of the Indian power program. The first issue we analyze is the current regulatory environment and guidelines in place for independent power producers and other generators, focusing on possible tradeoffs between prices and investor returns. The analysis shows that investor rates of return are significantly higher than the nominal 16% as stipulated by the Central Electricity Authority guidelines, and an uncertainty analysis reveals the relative importance of various input and project parameters. We discuss problems with the existing guidelines, and provide options for changes in policy. Adoption of modified guidelines that are more transparent and do not focus on project capital structures are likely to result in more affordable tariffs, less delays in project completion and yet provide adequate rates of return for investors. India's nuclear power program is based on indigenous materials and technology, with the potential for providing energy security for many decades. We examine the technical validity of this plan, especially the role of fast breeder reactors for extending the domestic uranium supplies. The analysis shows that breeding is unlikely to occur at anywhere near the rates envisioned, leading to a slow growth of fast breeder reactors. In addition, domestic uranium reserves restrict growth of Pressurized Heavy Water Reactors, which are likely to be the main contributors to nuclear capacity in the short term. To increase the share of nuclear power in the coming decades, India should consider the construction of a number of large thermal reactors based on indigenous and imported uranium. We also present policy options for such changes to India's nuclear power program. This dissertation examines in detail the policy, technology, and economics of an overland pipeline supplying natural gas to India and Pakistan. Such a pipeline would be shared by both countries, and would be a strong confidence building

    The confluence of technology development and market readiness is opening up major business opportunities for photovoltaic (PV) systems throughout the developing world. The National Renewable Energy Laboratory (NREL) and Sandia National Laboratories in Abuquerque (Sandia), working on behalf of the U.S. Department of Energy, have launched pilot projects in several countries throughout the world over the past 3 years. The focus of these pilot projects has been the development of in-country institutional capabilities necessary to deliver the promise of PV electricity to the rural populations. In addition to country-specific activities, NREL is conducting several technology, information, and partnership projects focused on further accelerating the education, training, business, and technology developments necessary to bridge the gap between promise and reality. This paper summarizes these efforts.

    Hoffheins, B.S.; Lauf, R.J.

    1988-01-01

    There have been many approaches to the development of gas sensor arrays for use in gas detection instruments and devices. Various techniques have been proposed to handle the signal processing and pattern recognition required to convert the outputs of these arrays into useful information such as the identities and concentrations of particular chemical species. In general, the pattern recognition techniques have not been developed as fully as have the sensor arrays. Materials issues, like sensor aging and drift, power requirements, and packaging are also problems that must be solved before gas sensor arrays can be incorporated into instruments for industrial and consumer markets. This paper describes significant thrusts in the areas of metal-oxide gas sensor array design and construction, related signature analysis and deconvolution, and materials issues. Recommendations are offered for future developments.

    This article presents a summary of research issues and opportunities in alternative energy source research identified by panels of experts assembled by the Engineering Directorate of the US National Science Foundation. The objective was to identify transformative research issues and opportunities to make alternative energy sources viable. The article presents motivations for energy research, grand challenges, and specific challenges in the research areas covered. The grand challenges identified for the United States include supplying 30% of US electricity from photovoltaics by 2030, supplying 25% of US electricity from wind by 2025, displacing 30% of US hydrocarbon use by 2030 with bio-based products, and providing a practical 250-300 W h/kg energy storage system by 2025. Similar challenges could be outlined along the same lines for the remainder of the world. Examples of specific areas of research focus identified as promising include high performance p-type transparent conductors, multijunction thin-film photovoltaic devices, defects in chalcogenide semiconductors, experimental study and numerical modeling of the fluid mechanics of airflow as applied to wind turbines, improved materials for wind turbines, methods for creating high energy density transportable biological feedstocks, biorefinery processes yielding infrastructure-compatible biofuels and biochemicals directly, and improved electrodes and electrolytes for Li ion batteries. Arguments for each of these as research priorities are given.

  7. Reactor-Based Plutonium Disposition: Opportunities, Options, and Issues

    SciTech Connect

    Greene, S.R.

    1999-07-17

    The end of the Cold War has created a legacy of surplus fissile materials (plutonium and highly enriched uranium) in the United States (U.S.) and the former Soviet Union. These materials pose a danger to national and international security. During the past few years, the U.S. and Russia have engaged in an ongoing dialog concerning the safe storage and disposition of surplus fissile material stockpiles. In January 1997, the Department of Energy (DOE) announced the U. S. would pursue a dual track approach to rendering approximately 50 metric tons of plutonium inaccessible for use in nuclear weapons. One track involves immobilizing the plutonium by combining it with high-level radioactive waste in glass or ceramic ''logs''. The other method, referred to as reactor-based disposition, converts plutonium into mixed oxide (MOX) fuel for nuclear reactors. The U.S. and Russia are moving ahead rapidly to develop and demonstrate the technology required to implement the MOX option in their respective countries. U.S. MOX fuel research and development activities were started in the 1950s, with irradiation of MOX fuel rods in commercial light water reactors (LWR) from the 1960s--1980s. In all, a few thousand MOX fuel rods were successfully irradiated. Though much of this work was performed with weapons-grade or ''near'' weapons-grade plutonium--and favorable fuel performance was observed--the applicability of this data for licensing and use of weapons-grade MOX fuel manufactured with modern fuel fabrication processes is somewhat limited. The U.S. and Russia are currently engaged in an intensive research, development, and demonstration program to support implementation of the MOX option in our two countries. This paper focuses on work performed in the U.S. and provides a brief summary of joint U.S./Russian work currently underway.

  12. Epidemiologic methods in analysis of scientific issues

    2003-10-01

    Studies of human populations provide much of the information that is used to evaluate compensation cases for hearing loss, including rates of hearing loss by age, and dose-response relationships. The reference data used to make decisions regarding workman's compensation is based on epidemiologic studies of cohorts of workers exposed to various noise levels. Epidemiology and its methods can be used in other ways in the courtroom; to assess the merits of a complaint, to support Daubert criteria, and to explain scientific issues to the trier of fact, generally a layperson. Using examples other than occupational noise induced hearing loss, these methods will be applied to respond to a complaint that hearing loss followed exposure to a sudden noise, a medication, or an occupational chemical, and thus was caused by said exposure. The standard criteria for assessing the weight of the evidence, and epidemiologic criteria for causality show the limits of such anecdotal data and incorporate quantitative and temporal issues. Reports of clusters of cases are also intuitively convincing to juries. Epidemiologic methods provide a scientific approach to assess whether rates of the outcome are indeed increased, and the extent to which increased rates provide evidence for causality.

    This report has been prepared for the Department of Energy, Office of Nuclear Energy (DOE-NE), for the purpose of providing a status report on the challenges and opportunities facing the U.S. commercial nuclear energy industry in the area of plant cooling water supply. The report was prompted in part by recent Second Circuit and Supreme Court decisions regarding cooling water system designs at existing thermo-electric power generating facilities in the U.S. (primarily fossil and nuclear plants). At issue in the courts have been Environmental Protection Agency regulations that define what constitutes “Best Technology Available” for intake structures that withdraw cooling water that is used to transfer and reject heat from the plant’s steam turbine via cooling water systems, while minimizing environmental impacts on aquatic life in nearby water bodies used to supply that cooling water. The report was also prompted by a growing recognition that cooling water availability and societal use conflicts are emerging as strategic energy and environmental issues, and that research and development (R&D) solutions to emerging water shortage issues are needed. In particular, cooling water availability is an important consideration in siting decisions for new nuclear power plants, and is an under-acknowledged issue in evaluating the pros and cons of retrofitting cooling towers at existing nuclear plants. Because of the significant ongoing research on water issues already being performed by industry, the national laboratories and other entities, this report relies heavily on ongoing work. In particular, this report has relied on collaboration with the Electric Power Research Institute (EPRI), including its recent work in the area of EPA regulations governing intake structures in thermoelectric cooling water systems.

    This article analyses two instances of abortion law reform in Latin America. In 2006, after a decades-long impasse, the highly controversial issue of abortion came to dominate the political agenda when Colombia liberalized its abortion law and Nicaragua adopted a total ban on abortion. The article analyses the central actors in the reform processes, their strategies and the opportunity contexts. Drawing on Htun's (2003) framework, it examines why these processes concluded with opposing legislative outcomes. The authors argue for the need to understand the state as a non-unitary site of politics and policy, and for judicial processes to be seen as a key variable in facilitating gender policy reforms in Latin America. In addition, they argue that ‘windows of opportunity’ such as the timing of elections can be critically important in legislative change processes. PMID:22069803

  16. Emerging technologies and web accessibility: research challenges and opportunities focussing on vision issues.

    This is a technological review paper focussed on identifying both the research challenges and opportunities for further investigation arising from emerging technologies, and it does not aim to propose any recommendation or standard. It is focussed on blind and partially sighted World Wide Web (Web) users along with others who use assistive technologies. The Web is a fast moving interdisciplinary domain in which new technologies, techniques and research is in perpetual development. It is often difficult to maintain a holistic view of new developments within the multiple domains which together make up the Web. This suggests that knowledge of the current developments and predictions of future developments are additionally important for the accessibility community. Web accessibility has previously been characterised by the correction of our past mistakes to make the current Web fulfil the original vision of access for all. New technologies were not designed with accessibility in mind and technologies that could be useful for addressing accessibility issues were not identified or adopted by the accessibility community. We wish to enable the research community to undertake preventative measures and proactively address challenges, while recognising opportunities, before they become unpreventable or require retrospective technological enhancement. This article then reviews emerging trends within the Web and Web Accessibility domains. PMID:21184625

    Spatially explicit tools for prioritizing conservation and land-use in human dominated landscapes are becoming common in recent years. Such efforts are also efficient in minimizing management costs and to provide future possible scenarios to aid management decisions. We propose and develop a spatially explicit framework and novel tool - Future Forest - for simulating scenarios for future forest management actions. We integrate both forest/vegetation characteristics, selected ecosystem services provided by corresponding forest/vegetation and nineteen possible threats and/or disturbances to forests that are either anthropogenic or occurring naturally, and may influence forest/vegetation characteristics and expected outcomes from forests. Our modelling framework provides options for necessary future actions either from conservation or from production forestry perspectives, and to ensure sustainable forest management in an area. In addition to that our threat assessment and mapping tool are useful in indentifying vulnerable zone of forests to specific anthropogenic, natural or other threats, and to take precautionary actions against each identified threats. We applied our modelling framework and spatial tool for measuring and mapping threats to a Bangladesh forest, with recommended actions to ensure sustainable forest management and to spatially prioritize zones for special management needs. We finally discuss issues and opportunities that our spatially explicit framework and novel tool may offer.

    Cell-penetrating peptides (CPPs), often vividly termed as the "Trojan Horse" peptides, have attracted considerable interest for the intracellular delivery of a wide range of cargoes, such as small molecules, peptides, proteins, nucleic acids, contrast agents, nanocarriers and so on. Some preclinical and clinical developments of CPP conjugates demonstrate their promise as therapeutic agents for drug discovery. There is increasing evidence to suggest that CPPs have the potential to cross several bio-barriers (e.g., blood-brain barriers, intestinal mucosa, nasal mucosa and skin barriers). Despite revolutionary process in many aspects, there are a lot of basic issues unclear for these entities, such as internalization mechanisms, translocation efficiency, translocation kinetics, metabolic degradation, toxicity, side effect, distribution and non-specificity. Among them, non-specificity remains a major drawback for the in vivo application of CPPs in the targeted delivery of cargoes. So far, diverse organelle-specific CPPs or controlled delivery strategies have emerged and improved their specificity. In this review, we will look at the opportunities of CPPs in clinical development, bio-barriers penetration and nanocarriers delivery. Then, a series of basic problems of CPPs will be discussed. Finally, this paper will highlight the use of various controlled strategies in the organelle-specific delivery and targeted delivery of CPPs. The purpose of this review will be to emphasize most influential advance in this field and present a fundamental understanding for challenges and utilizations of CPPs. This will accelerate their translation as efficient vectors from the in vitro setting into the clinic arena, and retrieve the entry art to "Troy". PMID:25151981

    This study sought to ascertain perceptions of communication responsibility in veterans identified as using more than one health care system, otherwise known as dual users. Three hundred and fifteen veterans identified as dual users completed a telephone-based survey including questions about their perspectives regarding communication in the context of dual use. Nearly half (47.3%) indicated that that they believed it was primarily their responsibility to either directly communicate or facilitate communication between their Veterans Affairs (VA) and non-VA providers. Only 11.3% reported that it should be the responsibility of their VA provider, 19.6% believed that their non-VA provider should be responsible, and 7.3% believed both should be involved. Finally, 14.4% believed another person was responsible, such as a system administrator or patient representative. Of those patients indicating that it was their responsibility, a majority (61.7%) indicated that they preferred active involvement in their health care. Patient-centered care allows patients the opportunity to help facilitate communication between multiple health care systems, such as when using VA and non-VA providers, if they so choose. However, given that patient preferences for involvement vary considerably, it is likely that a multifaceted approach to this problem is necessary, involving patients, providers, and other system-level stakeholders. These data suggest a need to inquire about preferred patient roles and counsel patients regarding methods of communication that may serve to decrease fragmentation of care. PMID:25010429

  2. Predictive Reactor Pressure Vessel Steel Irradiation Embrittlement Models: Issues and Opportunities

    SciTech Connect

    Odette, George Robert; Nanstad, Randy K

    2009-01-01

    Nuclear plant life extension to 80 years will require accurate predictions of neutron irradiation-induced increases in the ductile-brittle transition temperature ( T) of reactor pressure vessel (RPV) steels at high fluence conditions that are far outside the existing database. Remarkable progress in mechanistic understanding of irradiation embrittlement has led to physically motivated T correlation models that provide excellent statistical fi ts to the existing surveillance database. However, an important challenge is developing advanced embrittlement models for low fl ux-high fl uence conditions pertinent to extended life. These new models must also provide better treatment of key variables and variable combinations and account for possible delayed formation of late blooming phases in low copper steels. Other issues include uncertainties in the compositions of actual vessel steels, methods to predict T attenuation away from the reactor core, verifi cation of the master curve method to directly measure the fracture toughness with small specimens and predicting T for vessel annealing remediation and re-irradiation cycles.

    Helical Tomotherapy (HT) is a highly conformal image-guided radiation technique, introduced into clinical routine in 2006 at the Centro di Riferimento Oncologico Aviano (Italy). With this new technology, intensity-modulated radiotherapy (IMRT) is delivered using a helicoidal method. Here we present our dosimetric experiences using HT in 100 children, adolescents and young adults treated from May 2006 to February 2011. The median age of the patients was 13 years (range 1–24). The most common treated site was the central nervous system (50; of these, 24 were craniospinal irradiations), followed by thorax (22), head and neck (10), abdomen and pelvis (11), and limbs (7). The use of HT was calculated in accordance to the target dose conformation, the target size and shape, the dose to critical organs adjacent to the target, simultaneous treatment of multiple targets, and re-irradiation. HT has demonstrated to improve target volume dose homogeneity and the sparing of critical structures, when compared to 3D Linac-based radiotherapy (RT). In standard cases this technique represented a comparable alternative to IMRT delivered with conventional linear accelerator. In certain cases (e.g., craniospinal and pleural treatments) only HT generated adequate treatment plans with good target volume coverage. However, the gain in target conformality should be balanced with the spread of low-doses to distant areas. This remains an open issue for the potential risk of secondary malignancies (SMNs) and longer follow-up is mandatory. PMID:24213120

    Background Despite positive aspects of online forums as a qualitative research method, very little is known about practical issues involved in using online forums for data collection, especially for a qualitative research project. Objectives The purpose of this paper is to describe the practical issues that the researchers encountered in implementing an online forum as a qualitative component of a larger study on cancer pain experience. Method Throughout the study process, the research staff recorded issues ranged from minor technical problems to serious ethical dilemmas as they arose and wrote memos about them. The memos and written records of discussions were reviewed and analyzed using the content analysis suggested by Weber. Results Two practical issues related to credibility were identified: a high response and retention rate and automatic transcripts. An issue related to dependability was the participants’ easy forgetfulness. The issues related to confirmability were difficulties in theoretical saturation and unstandardized computer and Internet jargon. A security issue related to hacking attempts was noted as well. Discussion The analysis of these issues suggests several implications for future researchers who want to use online forums as a qualitative data collection method. PMID:16849979

    1996-10-01

    This paper discusses the technical potential for hydrogen used as an energy storage medium to couple time-dependent renewable energy into time-dependent electric utility loads. This analysis will provide estimates of regional and national opportunities for hydrogen production, storage and conversion, based on current and near-term leading renewable energy and hydrogen production and storage technologies. Appropriate renewable technologies, wind, photovoltaics and solar thermal, are matched to their most viable regional resources. The renewables are assumed to produce electricity which will be instantaneously used by the local utility to meet its loads; any excess electricity will be used to produce hydrogen electrolytically and stored for later use. Results are derived based on a range of assumptions of renewable power plant capacity and fraction of regional electric load to be met (e.g., the amount of hydrogen storage required to meet the Northwest region`s top 10% of electric load). For each renewable technology national and regional totals will be developed for maximum hydrogen production per year and ranges of hydrogen storage capacity needed in each year (hydroelectric case excluded). The sensitivity of the answers to the fraction of peak load to be served and the land area dedicated for renewable resources are investigated. These analyses can serve as a starting point for projecting the market opportunity for hydrogen storage and distribution technologies. Sensitivities will be performed for hydrogen production, conversion. and storage efficiencies representing current and near-term hydrogen technologies.

    1980-01-01

    A small scale hydroelectric (SSH) facility is defined as an existing dam that can be retrofitted to produce 25 MW or less capacity. An estimate of the total SSH potential in the United States indicates there are 4979 sites with 8775 MW capacity and 25,126 GWh average annual energy. This represents approximately 1% of existing total installed electrical capacity from all sources in the US. Some of the major environmental issues that must be analyzed to determine potential for adverse impact at SSH sites include dredging, fish passage, water level fluctuation, and instream (minimum) flow. Each of these issues is discussed. It is concluded that development of the SSH resource represents a good energy investment and that the attributes of renewable energy and the emphasis on existing dams as opposed to new dam construction are positive features from the environmental standpoint.

    2011-07-01

    Currently, proliferation risk assessment models are designed to evaluate only a portion of the overall risk, focusing exclusively on either technological or social factors to determine the extent of a threat. Many of these models are intended to act as a means of predicting proliferation potential rather than assessing the system as a whole, ignoring the ability to enhance mitigating factors and manage, rather just establish the presence of, the threat. While the information garnered through these forms of analysis is necessary, it remains incomplete. By incorporating political, social, economic and technical capabilities as well as human factors such as intent into a single, multi-faceted risk management model, proliferation risk can be evaluated more effectively. Framing this information around how to improve and expand the Regime already in place and establishing where there are gaps in the system allows for a more complete approach to risk management, mitigation and resource allocation. The research conducted here seeks to combine all three elements (intent, capability and opportunity) in a comprehensive evaluation which incorporates an assessment of state-level variables, possible proliferation pathways and technical capability. Each portion of the analysis is carried out independently then combined to illustrate the full scope of a State's nuclear infrastructure while showing areas of weakness in the institutional framework.

  5. Cross-border issues in the development of medical tourism in Malaysia: legal challenges and opportunities.

    PubMed

    Nemie, Puteri; Kassim, Jahn

    2009-08-01

    Strategically located at the crossroads of Asia, Malaysia has become one of the key players in the fast-growing and lucrative market for health care services in Asia. Medical travel across international boundaries has been made possible through affordable airfares and the favourable exchange rates of the Malaysian ringgit has contributed to the rise of the "medical tourism phenomenon" where medical travel is combined with visiting popular tourist destinations in Malaysia. Further, competitive medical fees and modern medical facilities have also made Malaysia a popular destination for medical tourists. Nevertheless, the increased number of foreign patients has opened up possibilities of Malaysian health care providers being subjected to malpractice claims and triggering a myriad of cross-border legal issues. Presently, there is no internationally accepted legal framework to regulate medical tourism and issues of legal redress in relation to unsatisfactory provision of treatment across international boundaries. The economic benefits of medical tourism must be based upon a solid legal regulatory framework and strong ethical standards as well as upon high-quality medical and health care services. It is therefore important to assess the existing legal framework affecting the development of medical tourism in Malaysia in order to explore the gaps, deficiencies and possibilities for legal and regulatory reform.

    This study aimed to review the emerging findings regarding E-health interventions for eating disorders and to critically discuss emerging issues as well as challenges for future research. Internet-based cognitive behavioral therapy and guided self-help have demonstrated promising results in terms of reducing eating disorder psychopathology. Emerging findings also suggest that E-health interventions reach an underserved population and improve access to care. The use of smartphone applications is becoming increasingly popular and has much potential although their clinical utility and effectiveness is presently unknown and requires investigation. Important challenges include the diagnostic process in E-health interventions, the optimization of E-health within existing health care models, and the investigation and implementation of blended care. More high-quality research is needed to bring the field forward and to determine the place for E-health in our health care service delivery systems. PMID:26946513

    2011-05-01

    There are several recent examples where clinically significant, safety-related, drug effects on hemodynamics or cardiac function were not apparent until large clinical trials were completed or the drugs entered the consumer market. Such late-stage safety issues can have significant impact on patient health and consumer confidence, as well as ramifications for the regulatory, pharmaceutical, and financial communities. This manuscript provides recommendations that evolved from a 2009 HESI workshop on the need for improved translation of nonclinical cardiovascular effects to the clinical arena. The authors conclude that expanded and improved efforts to perform sensitive yet specific evaluations of functional cardiovascular parameters in nonclinical studies will allow pharmaceutical companies to identify suspect drugs early in the discovery and development process while allowing promising drugs to proceed into clinical development.

  8. Opportunities for biotechnology and policy regarding mycotoxin issues in international trade.

    PubMed

    Kendra, David F; Dyer, Rex B

    2007-10-20

    Despite being introduced more than a decade ago, agricultural biotechnology still remains framed in controversy impacting both the global economy and international regulations. Controversies surrounding agricultural biotechnology produced crops and foods commonly focus on human and environmental safety, intellectual property rights, consumer choice, ethics, food security, poverty reduction and environmental conservation. Originally, some consumers were reluctant to accept the first generation agricultural biotechnology products because they appeared to primarily benefit agricultural producers; however, it is clear from continued evaluations that these technologies also improved both the safety and wholesomeness of food and helped improve the environment. Plants engineered to resist insect pests and tolerate less toxic pesticides resulted in improved yields thereby enabling farmers to produce more food per acre while reducing the need for herbicides, pesticides, and water and tilling. An indirect benefit of reduced pest damage in transgenic corn expressing genes to control insect pests is lower levels of mycotoxins, most notably those caused by the genus Fusarium. Mycotoxins are an important regulatory issue globally because of their toxic and carcinogenic potential to humans and animals. Complicating this issue is the fact that toxicological databases for mycotoxins are relatively incomplete compared to other food contaminants. Current debates about agricultural biotechnology and mycotoxins reveal significant differences in perception of associated risks and benefits. When faced with uncertainty, regulators tend to set limits as low as possible. Additionally, some regulators invoke the "Precautionary Principle" when limited information is available or disputes over interpretation exist for possible contaminants, including mycotoxins. A major concern regarding use of the "Precautionary Principle" is the appearance that regulators can justify setting any limit on the

    Microbiome is a novel research field related with a variety of chronic inflamatory diseases. Technically, there are two major approaches to analysis of microbiome: metataxonome by sequencing the 16S rRNA variable tags, and metagenome by shot-gun sequencing of the total microbial (mainly bacterial) genome mixture. The 16S rRNA sequencing analyses pipeline includes sequence quality control, diversity analyses, taxonomy and statistics; metagenome analyses further includes gene annotation and functional analyses. With the development of the sequencing techniques, the cost of sequencing will decrease, and big data analyses will become the central task. Data standardization, accumulation, modeling and disease prediction are crucial for future exploit of these data. Meanwhile, the information property in these data, and the functional verification with culture-dependent and culture-independent experiments remain the focus in future research. Studies of human microbiome will bring a better understanding of the relations between the human body and the microbiome, especially in the context of disease diagnosis and therapy, which promise rich research opportunities.

    OBJECTIVE: To describe some of the unique aspects of medical care offered under workers' compensation insurance systems and discuss the major policy considerations relevant to health services researchers undertaking investigations in this area. BACKGROUND AND FINDINGS: State-based workers' compensation (WC) insurance systems requiring employers to pay for medical care and wage replacement for workplace injuries and illnesses were first developed between 1910 and 1920 in the United States. Employers are generally required to purchase state-regulated workers' compensation insurance that includes first-dollar payment for all medical and rehabilitative services and payment of lost wages to workers with work-related illness or injury. Injured workers have variable but usually limited latitude in choosing their health care provider. Employers and workers' compensation insurers have incentives for controlling both the cost of medical care and lost wages. CONCLUSION: The major policy issues in WC medical care--the effect of patient choice of provider and delivery system structure, the ensuring of high-quality care, the effect of integrating benefits, and investigation of the interrelationships between work, health, and productivity--can be informed by current studies in health services research and by targeted future studies of workers' compensation populations. These studies must consider the extent of patient choice of physician, the regulatory environment, the unique role of the workplace as a risk and modifying factor, and the complex interaction between health and disability insurance benefits.

    The present study assesses the link between choice of violent methods of suicide and race from the standpoint of two perspectives: differential socio-acceptability and differential availability. To the extent that African Americans form a subculture of violence, and are more exposed to violence, we would expect them to choose violent methods of suicide. Data are from the 1990 mortality detail file of the U.S. Public Health Service and correspond to 19,580 male suicides. The results of a multivariate logistic regression analysis indicate that African Americans are 2.24 times more likely than Caucasians to choose violent methods of suicide. Although they are less likely to own firearms, African Americans are more likely than Caucasians to choose violent methods of suicide. PMID:16040580

  13. Why Map Issues? On Controversy Analysis as a Digital Method

    PubMed Central

    2015-01-01

    This article takes stock of recent efforts to implement controversy analysis as a digital method in the study of science, technology, and society (STS) and beyond and outlines a distinctive approach to address the problem of digital bias. Digital media technologies exert significant influence on the enactment of controversy in online settings, and this risks undermining the substantive focus of controversy analysis conducted by digital means. To address this problem, I propose a shift in thematic focus from controversy analysis to issue mapping. The article begins by distinguishing between three broad frameworks that currently guide the development of controversy analysis as a digital method, namely, demarcationist, discursive, and empiricist. Each has been adopted in STS, but only the last one offers a digital “move beyond impartiality.” I demonstrate this approach by analyzing issues of Internet governance with the aid of the social media platform Twitter.

    2011-12-01

    A workshop on The Role of Two-Year Colleges in Geoscience Education and Broadening Participation in the Geosciences was held at Northern Virginia Community College in June 2010 to identify issues, challenges, and opportunities for geoscience faculty and students in two-year colleges (2YC) and to make recommendations for strengthening this component of the geoscience community. Given the wide diversity of 2YC students, a long term goal for this workshop was to work toward broadening the participation of underrepresented students to the geosciences. The workshop included sessions on strategies for supporting all students to be successful, the role of 2YC in broadening participation in the geosciences, and preparing geoscience students for the future (recruiting and retaining students in the geosciences, career preparation and workforce development, and transfer and 2YC and 4YC partnerships). Conversations between participants and professional organizations and societies focused on how increased communication with 2YC faculty could support faculty and students from two-year colleges. Participants considered strategies for addressing isolation and building community including interdisciplinary collaborations, scholarly practices, using Web 2.0, and working with adjunct faculty. Working groups addressed the following topics: establishment of a geoscience 2YC community, best practices for geoscience 2YC programs, faculty professional development, recruitment and retention of students, diversity in the geosciences, the role of 2YC in K-12 teacher preparation, and ocean science education in 2YC. Recommendations included the need to collect and disseminate information about 2YC including demographic information and best practices of 2YC geoscience programs, the desire to establish an organization for 2YC geoscience faculty, more opportunities to communicate (workshops and electronic communications), and other approaches for supporting 2YC students, faculty, and programs

    Sommers, M S; Woods, S L; Courtade, M A

    1993-01-01

    Criterion-related validity of the thermodilution cardiac output technique for cardiac output measurement has to have a high correlation (r = .91 to .98) with the direct Fick method, the gold standard of cardiac output measurement. Issues that can affect validity of the measurements include the position of the pulmonary artery catheter, the rate of injection of the indicator solution, the volume and temperature of the injectate, the timing of the injection of indicator solution during the respiratory cycle, the position of the subject, and the presence of concomitant infusions. Variation in measurement can be limited by considering the delivery system for the indicator solution, by recording time-temperature cardiac output curves, and by considering normal biologic variations.

    that also have not been fully addressed. This document contains two types of papers that seek to fill part of this void. Some of the papers describe analytical methods that can be applied to one of the five steps of the damage function approach. The other papers discuss some of the complex issues that arise in trying to estimate externalities. This report, the second in a series of eight reports, is part of a joint study by the U.S. Department of Energy (DOE) and the Commission of the European Communities (EC)* on the externalities of fuel cycles. Most of the papers in this report were originally written as working papers during the initial phases of this study. The papers provide descriptions of the (non-radiological) atmospheric dispersion modeling that the study uses; reviews much of the relevant literature on ecological and health effects, and on the economic valuation of those impacts; contains several papers on some of the more complex and contentious issues in estimating externalities; and describes a method for depicting the quality of scientific information that a study uses. The analytical methods and issues that this report discusses generally pertain to more than one of the fuel cycles, though not necessarily to all of them. The report is divided into six parts, each one focusing on a different subject area.

  18. Hawaiian temples and their orientations: issues of method and interpretation

    NASA Astrophysics Data System (ADS)

    Ruggles, Clive L. N.

    2015-08-01

    In 2002 I began a collaboration with Pat Kirch (Berkeley) to survey the temple sites (heiau) in the Kahikinui and Kaupo districts of southern Maui, and study their orientations and potential astronomical significance. Our investigations of over 70 temples in the area were completed in 2011 and are due for publication in 2016. Pat Kirch will present some of our main conclusions in his keynote talk within FM2. In this paper I propose to concentrate on issues of field methodology and procedure that have wider implications for developments in method and practice within archaeoastronomy. Methodologically, temple sites in the Hawaiian Islands constitute a "halfway house" between prehistoric monuments in Europe, where the only evidence is archaeological and studies of orientations tend to follow formal, "data-driven" or statistical, approaches, and Mesoamerica, where the existence of pre-conquest written records and inscriptions and post-conquest ethnohistory relegate "alignment studies" to a secondary role. In Hawai‘i, cultural data, including oral histories recorded after conquest, provide a finer balance between historical accounts and the physical evidence. Selection issues at the Maui temple sites include distinguishing marginal temple sites from house sites and identifying the intended direction of orientation at complex structures. Initial analyses of the principal orientations identified clusterings in orientation which were interpreted as relating to different gods, and particular the war-god Ku and the god of dryland agriculture, Lono. Later, more comprehensive surveys revealed evidence of observing platforms and foresights at some of the Lono temples, suggesting that systematic observations were made of the Pleiades, known from the ethnohistory to be of particular calendrical significance. This type of alignment evidence is too subjective to be sustained on the basis of a formal analysis alone but, given the historical context, provides a more robust cultural

  19. FOREWORD: Special issue on Statistical and Probabilistic Methods for Metrology

    NASA Astrophysics Data System (ADS)

    2006-08-01

    This special issue of Metrologia is the first that is not devoted to units, or constants, or measurement techniques in some specific field of metrology, but to the generic topic of statistical and probabilistic methods for metrology. The number of papers on this subject in measurement journals, and in Metrologia in particular, has continued to increase over the years, driven by the publication of the Guide to the Expression of Uncertainty in Measurement (GUM) [1] and the Mutual Recognition Arrangement (MRA) of the CIPM [2]. The former stimulated metrologists to think in greater depth about the appropriate modelling of their measurements, in order to provide uncertainty evaluations associated with measurement results. The latter obliged the metrological community to investigate reliable measures for assessing the calibration and measurement capabilities declared by the national metrology institutes (NMIs). Furthermore, statistical analysis of measurement data became even more important than hitherto, with the need, on the one hand, to treat the greater quantities of data provided by sophisticated measurement systems, and, on the other, to deal appropriately with relatively small sets of data that are difficult or expensive to obtain. The importance of supporting the GUM and extending its provisions was recognized by the formation in the year 2000 of Working Group 1, Measurement uncertainty, of the Joint Committee for Guides in Metrology. The need to provide guidance on key comparison data evaluation was recognized by the formation in the year 2001 of the BIPM Director's Advisory Group on Uncertainty. A further international initiative was the revision, in the year 2004, of the remit and title of a working group of ISO/TC 69, Application of Statistical Methods, to reflect the need to concentrate more on statistical methods to support measurement uncertainty evaluation. These international activities are supplemented by national programmes such as the Software Support

  2. Efficiency and concordance of alternative methods for minimizing opportunity costs in conservation planning.

    2008-08-01

    Scarce resources and competing land-use goals necessitate efficient biodiversity conservation. Combining multicriteria analysis with conservation decision-support tools improves efficiency of conservation planning by maximizing outcomes for biodiversity while minimizing opportunity costs to society. An opportunity cost is the benefit that could have been received by taking an alternative course of action (i.e., costs to society of protecting an area for biodiversity rather than developing it for some other use). Although different ways of integrating multiple opportunity costs into conservation planning have been suggested, there have been no tests as to which method is most efficient. We compared the relative efficiency of 3 such procedures(Faith & Walker [1996], Sarkar et al. [2004], and a procedure of our own design) in a systematic conservation-planning framework for the Milne Bay Province of Papua New Guinea. We devised 14 opportunity costs and assigned these to 3 scenarios representing different conservation planning concerns: food security, macro-economic development, and biodiversity persistence. For each scenario, we compared the efficiency of the 3 methods in terms of amount of biodiversity protected relative to total expenditure for each opportunity cost. All 3 methods captured similar amounts of biodiversity, but differed in total cost. Our method had the least overall cost and was therefore most efficient. Nevertheless, there was a high correlation and geographical concordance among all 3 methods, indicating a high degree of spatial overlap. This suggests that choosing an appropriate approach may often depend on contextual factors related to the design of the planning question, rather than efficiency alone. PMID:18637906

    The development of a new medicinal product is a long and costly process in particular due to the regulatory requirements for quality, safety and efficacy. There is a common interest to increase the efficiency of drug development and to provide new, better quality medicinal products much faster to the public. One possible way to economize time and costs, as well as to consider animal protection issues, is to introduce new alternative methods into non-clinical toxicity testing. Currently, animal tests are mandatory for the evaluation of acute toxicity of chemicals and new drugs. The replacement of the in vivo tests by alternative in vitro assays would offer the opportunity to screen and assess numerous compounds at the same time, to predict acute oral toxicity and thus accelerate drug development. Moreover, the substitution of in vivo tests by in vitro methods shows a proactive pursuit of ethical and animal welfare issues. Importantly, the implementation of in vitro assays for acute oral toxicity would require the establishment of common test guidelines across the EU, USA and Japan, i.e., the regions of ICH (International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use). Presently, alternative in vitro tests are being investigated internationally. Yet, in order to achieve regulatory acceptance and implementation of in vitro assays, convincing results from validation studies are required. In this review, we discuss the current regulatory status of acute oral toxicity testing and point out achievements of alternative methods. We describe the application of in vitro tests, correlating in vitro with in vivo data. The use of in vitro data to predict in vivo acute oral toxicity is analyzed using the Registry of Cytotoxicity, an official independent database. We have then analyzed opportunities and drawbacks for future implementation of in vitro test methods, with particular focus on industrial use. PMID:18362045

    Rosser, Sue V.; Zieseniss, Mireille

    A survey of fiscal year 1997 POWRE (Professional Opportunities for Women in Research and Education) awardees from the National Science Foundation revealed that women engineers and scientists face similar issues, challenges, and opportunities and think that the laboratory climate has similar impacts on their careers. Separating responses of women scientists from those of women engineers revealed that 70% of both groups listed balancing work with family responsibilities as the most difficult issue. Discrepancies in percentages of women, coupled with differences among disciplinary and subdisciplinary cultures within science, engineering, mathematics, and technology fields, complicate work climates and their impact on women's careers. More frequently than women scientists, women engineers listed issues such as (a) low numbers of women leading to isolation, (b) lack of camaraderie and mentoring, (c) gaining credibility/respect from peers and administrators, (d) time management, (e) prioritizing responsibilities due to disproportionate demands, and (f) learning the rules of the game to survive in a male-dominated environment. Women engineers also listed two positive issues more frequently than women scientists: active recruitment/more opportunities for women and impact of successful women in the profession. The small number of women engineers may explain these results and suggests that it may be inappropriate to group them with other women scientists for analysis, programs, and policies.

  6. The dating of ore genesis with using of sulfides: new opportunities of Sm-Nd method

    Within the Fennoscandian Shield only on the surface there are hundreds of mafic-ultramafic intrusions, and on geophysical data - more than a thousand. Existing estimates of the ore potential related to the very costly and time-consuming drilling and analytical work (Mitrofanov, 2006). One of the express-and relatively inexpensive methods is a Sm-Nd dating of rocks and minerals. Feature of the Sm-Nd method is that it allows to use rock-forming minerals for the dating process. Our studies have shown that along with rock-forming, ore minerals (sulfides) can be used to determine the ore genesis time of industrially important geological sites, since exactly with the sulfides the industry Pt-Pd mineralization is closely connected. Age determination on sulphides is a direct method, since in this case the time of mineralization is determined directly, which can consist with the time of crystallization of the parent magma (syngenetic ores), and do not match - epigenetic, redeposited ore. Within Fennoscandia the both types of syngenetic and epigenetic manifestation of ore are known and setting of milestones mineralization is essential for understanding the evolution of ore-bearing magmatic sources and assess the prospects for PGE of many mafic massifs. Studies have shown that Sm-Nd dating method is applicable to both types of ore and dates obtained agree well with the known U-Pb ages of zircon or with key scenes of Svekofennian metamorphic events (eg, Sm-Nd age of the redeposited ores Ahmavaary - about 1900 Ma). One of the problems of Sm-Nd systematics of sulfides is the question of internal inclusions with high contents of REE. In this case, obtained isotope-geochronological features may not correspond to real geological events. To address this issue, the study of internal structure of sulfide minerals was carried out by CL high-local equipment - a scanning electron microscope LEO 1450 with cathodoluminescent attachment PanaCL. Studies have shown that these inclusions are

    There is a diversity of human reliability analysis (HRA) methods available for use in assessing human performance within probabilistic risk assessment (PRA). Due to the significant differences in the methods, including the scope, approach, and underlying models, there is a need for an empirical comparison investigating the validity and reliability of the methods. To accomplish this empirical comparison, a benchmarking study is currently underway that compares HRA methods with each other and against operator performance in simulator studies. In order to account for as many effects as possible in the construction of this benchmarking study, a literature review was conducted, reviewing past benchmarking studies in the areas of psychology and risk assessment. A number of lessons learned through these studies are presented in order to aid in the design of future HRA benchmarking endeavors.

    2012-11-01

    Safe management of electronic and electrical waste (e-waste/WEEE) is becoming a major problem for many countries around the world. In particular, developing countries face a number of issues with the generation, transboundary movement and management of e-waste. It is estimated that the world generates around 20-50 million tonnes of e-waste annually, most of it from Asian countries. Improper handling of e-waste can cause harm to the environment and human health because of its toxic components. Several countries around the world are now struggling to deal with this emerging threat. Although the current emphasis is on end-of-life management of e-waste activities, such as reuse, servicing, remanufacturing, recycling and disposal, upstream reduction of e-waste generation through green design and cleaner production is gaining much attention. Environmentally sound management (ESM) of e-waste in developing countries is absent or very limited. Transboundary movement of e-waste is a major issue throughout the region. Dealing with the informal recycling sector is a complex social and environmental issue. There are significant numbers of such challenges faced by these countries in achieving ESM of e-waste. This article aims to present a review of challenges and issues faced by Asian countries in managing their e-waste in a sustainable way. PMID:22851536

  1. The Natural Gas Dilemma in New England's Electricity Sector: Experts' Perspectives on Long Term Climate Issues and Policy Opportunities

    NASA Astrophysics Data System (ADS)

    Griffith, Steven

    This thesis is an interpretive analysis of experts' perspectives on the climate implications of New England's reliance on natural gas for electricity generation. Specifically, this research, conducted through interviews and literature review, examines experts' opinions on the desired role of natural gas within the regional electricity sector, alternative energy resources, and state and regional policy opportunities toward the achievement of New England's ambitious long-term greenhouse gas reduction goals. Experts expressed concern about the climate dilemma posed by a dependence on natural gas. However, interviews revealed that short-term reliability and cost considerations are paramount for many experts, and therefore a reliance on natural gas is the existing reality. To incentivize renewable generation technologies for the purposes of long-term climate stabilization, experts advocated for the expanded implementation of renewable portfolio standard, net metering, and feed-in tariff policies. More broadly, interviewees expressed the need for an array of complementary state and regional policies.

  2. California Energy Incentive Programs: An Annual Update on Key Energy Issues and Financial Opportunities for Federal Sites in California

    SciTech Connect

    2011-12-01

    A spate of recently enacted energy legislation and associated program changes is providing numerous opportunities to help California federal energy managers cut costs and meet their renewables, energy efficiency and GHG emissions goals. In April 2011, Governor Jerry Brown approved the nation’s most ambitious renewable portfolio standard (RPS), which requires 33% of the state’s electricity to come from renewable energy sources by 2020. Policy changes that will support the RPS include expanded eligibility rules that fill previous gaps in incentives for certain sizes of on-site renewable energy systems. Program updates described in this document include: $200 million more in funding for California Solar Initiative rebates to commercial and industrial customers; an increase in the eligible system size for the Feed-In-Tariff (FIT) from 1.5MW to 3MW; and pending changes that may allow customer-side systems to sell tradable renewable energy credits (TRECs) to entities with RPS compliance obligations in California.

    Monitoring the change in expression patterns over time provides the distinct possibility of unraveling the mechanistic drivers characterizing cellular responses. Gene arrays measuring the level of mRNA expression of thousands of genes simultaneously provide a method of high-throughput data collection necessary for obtaining the scope of data required for understanding the complexities of living organisms. Unraveling the coherent complex structures of transcriptional dynamics is the goal of a large family of computational methods aiming at upgrading the information content of time-course gene expression data. In this review, we summarize the qualitative characteristics of these approaches, discuss the main challenges that this type of complex data present, and, finally, explore the opportunities in the context of developing mechanistic models of cellular response.

  5. Random Sampling of Quantum States: a Survey of Methods. And Some Issues Regarding the Overparametrized Method

    NASA Astrophysics Data System (ADS)

    Maziero, Jonas

    2015-12-01

    The numerical generation of random quantum states (RQS) is an important procedure for investigations in quantum information science. Here, we review some methods that may be used for performing that task. We start by presenting a simple procedure for generating random state vectors, for which the main tool is the random sampling of unbiased discrete probability distributions (DPD). Afterwards, the creation of random density matrices is addressed. In this context, we first present the standard method, which consists in using the spectral decomposition of a quantum state for getting RQS from random DPDs and random unitary matrices. In the sequence, the Bloch vector parametrization method is described. This approach, despite being useful in several instances, is not in general convenient for RQS generation. In the last part of the article, we regard the overparametrized method (OPM) and the related Ginibre and Bures techniques. The OPM can be used to create random positive semidefinite matrices with unit trace from randomly produced general complex matrices in a simple way that is friendly for numerical implementations. We consider a physically relevant issue related to the possible domains that may be used for the real and imaginary parts of the elements of such general complex matrices. Subsequently, a too fast concentration of measure in the quantum state space that appears in this parametrization is noticed.

  6. Developing integrated methods to address complex resource and environmental issues

    2016-01-01

    IntroductionThis circular provides an overview of selected activities that were conducted within the U.S. Geological Survey (USGS) Integrated Methods Development Project, an interdisciplinary project designed to develop new tools and conduct innovative research requiring integration of geologic, geophysical, geochemical, and remote-sensing expertise. The project was supported by the USGS Mineral Resources Program, and its products and acquired capabilities have broad applications to missions throughout the USGS and beyond.In addressing challenges associated with understanding the location, quantity, and quality of mineral resources, and in investigating the potential environmental consequences of resource development, a number of field and laboratory capabilities and interpretative methodologies evolved from the project that have applications to traditional resource studies as well as to studies related to ecosystem health, human health, disaster and hazard assessment, and planetary science. New or improved tools and research findings developed within the project have been applied to other projects and activities. Specifically, geophysical equipment and techniques have been applied to a variety of traditional and nontraditional mineral- and energy-resource studies, military applications, environmental investigations, and applied research activities that involve climate change, mapping techniques, and monitoring capabilities. Diverse applied geochemistry activities provide a process-level understanding of the mobility, chemical speciation, and bioavailability of elements, particularly metals and metalloids, in a variety of environmental settings. Imaging spectroscopy capabilities maintained and developed within the project have been applied to traditional resource studies as well as to studies related to ecosystem health, human health, disaster assessment, and planetary science.

  7. Brokered dialogue: A new research method for controversial health and social issues

    PubMed Central

    2012-01-01

    Abstract Background Dialogue is a foundational feature of social life and an important way in which we come to understand one another. In situations of controversy dialogue is often absent because of a range of social barriers. We have developed a new film-based qualitative research method for studying controversial issues in healthcare and social policy. We call this method Brokered Dialogue. Theoretically informed by the traditions in narrative inquiry and visual anthropology, the method is premised on the idea that dialogue possesses features making it unique as a generator of new knowledge and opportunities for social intervention. Film is not only an extraordinarily rich data source, but an excellent medium for knowledge transfer and dissemination. Discussion The paper introduces the Brokered Dialogue method. We outline its critical steps, including the procedures for sampling, data collection and data analysis of both textual and visual data. Participants in a Brokered Dialogue engage in filmed interviews that capture their perspectives on a given topic; they then share their perspectives with, and pose questions of, one another through the medium of film. Using a participatory editing process, only footage that participants feel comfortable showing to others is incorporated. This technique offers participants a ‘safe’ space for respectful interaction. The editing process itself is analytic, and the final assembly of footage approximates a dialogue on the topic at hand. A link to a film produced from a project piloting the method is provided to demonstrate its real world application. Summary Brokered Dialogue is a method for promoting respectful interactions among those with seemingly divergent views on a controversial topic and for discovering critical points of divergence that may represent pathways for improvement. While the end product is a ‘film’, the goal is to have these films used as catalysts for ongoing respectful dialogue and problem

    Placebo medication regimens may help educate students about adherence issues. In this randomized trial, 23 third-year medical students took a 2-week placebo regimen mimicking highly active antiretroviral therapy (HAART) during their medicine clerkship; 15 students served as controls. Although no effect was demonstrated from this intervention on an evaluation instrument examining attitudes and beliefs about medication nonadherence, all 23 student-subjects agreed in postintervention interviews that the experience was useful and had learning value. Representative comments from the 19 subjects who expanded their interview responses portray this intervention as an eye-opening and unique method for teaching students about medication adherence issues.

    The safety of traditional Chinese medicine (TCM) is a major strategic issue that involves human health. With the continuous improvement in disease prevention and treatment, the export of TCM and its related products has increased dramatically in China. However, the frequent safety issues of Chinese medicine have become the ‘bottleneck’ impeding the modernization of TCM. It was proved that mycotoxins seriously affect TCM safety; the pesticide residues of TCM are a key problem in TCM international trade; adulterants have also been detected, which is related to market circulation. These three factors have greatly affected TCM safety. In this study, fast, highly effective, economically-feasible and accurate detection methods concerning TCM safety issues were reviewed, especially on the authenticity, mycotoxins and pesticide residues of medicinal materials.

  3. Forensic psychiatric evaluations: an overview of methods, ethical issues, and criminal and civil assessments.

    PubMed

    2015-05-01

    Forensic psychiatry is frequently defined as the branch of psychiatry that deals with issues arising in the interface between psychiatry and the law. Psychiatrists are called on by the legal system to provide testimony in a wide variety of cases, criminal and civil. In criminal cases, forensic psychiatrists may be asked to comment on the competence of a person to make decisions throughout all the phases of criminal investigation, trial, and punishment. These include the competence to stand trial, to plead guilty, to be sentenced, to waive appeal, and to be executed. In civil cases, forensic psychiatric experts are asked to evaluate a number of civil competences, including competence to make a will or contract or to make decisions about one's person and property. Psychiatrists are also called on to testify about many other issues related to civil cases. Forensic psychiatrists who work with children and adolescents are frequently involved in evaluations and testimonies concerning juvenile delinquency, child custody, termination of parental rights, and other issues. As such, forensic psychiatric experts have now developed into a reputable and well-known group of professionals. Forensic evaluation methods, ethical issues related to forensic psychiatric practice, and some common criminal and civil forensic psychiatric evaluations are discussed in this overview.

    Recently-developed fast-response gas analysers capable of measuring atmospheric N2O with high precision (< 50 ppt) at a rate of 10 Hz are becoming more widely available. These instruments are capable of measuring N2O fluxes using the eddy covariance method, with significantly less effort and uncertainty than previous instruments have allowed. However, there are still many issues to overcome in order to obtain accurate and reliable flux data. The signal-to-noise ratio of N2O measured using these instruments is still two to three orders of magnitude smaller than that of CO2. The low signal-to-noise ratio can lead to systematic uncertainties, in the eddy covariance method, the most significant being in the calculation of the time lag between gas analyser and anemometer by maximisation of covariance (Langford et al., 2015). When signal-to-noise ratio is relatively low, as it is with many N2O measurements, the maximisation of covariance method can systematically overestimate fluxes. However, if constant time lags are assumed, then fluxes will be underestimated. This presents a major issue for N2O eddy covariance measurements. In this presentation we will focus on the signal to noise ratio for an Aerodyne quantum cascade laser (QCL). Eddy covariance flux measurements from multiple agricultural sites across the UK were investigated for potential uncertainties. Our presentation highlights some of these uncertainties when analysing eddy covariance data and offers suggestions as to how these issues may be minimised.

    Allergic contact dermatitis (ACD) is a delayed-type hypersensitivity immune reaction mediated by T-lymphocytes as a result of repeated exposure of an allergen primarily on skin. ACD accounts for up to 95% of occupational skin diseases, with epoxy resins implicated as one of the most common causes of ACD. Efficient high-throughput in vitro screening for accurate identification of compounds and materials that may pose hazardous risks in the workplace is crucial. At present, the murine local lymph node assay is the 'method of choice' for predicting the sensitizing potency of contact allergens. As the 3Rs principles of reduction, refinement, and replacement in animal testing has gained political and economic momentum, several in vitro screening methods have been developed for identifying potential contact allergens. To date, these latter methods have been utilized primarily to assess the skin sensitizing potential of the chemical components of cosmetic products with scant research attention as to the applicability of these methods to industrial chemicals, particularly epoxy resins. Herein we review the currently utilized in vitro methods and identify the knowledge gaps with regard to assessing the generalizability of in vitro screening methods for assessing the skin sensitizing potential of industrial chemicals.

    The debate over the suitability of molecular biological methods for the enumeration of regulatory microbial parameters (e.g. Faecal Indicator Organisms [FIOs]) in bathing waters versus the use of traditional culture-based methods is of current interest to regulators and the science community. Culture-based methods require a 24-48hour turn-around time from receipt at the laboratory to reporting, whilst quantitative molecular tools provide a more rapid assay (approximately 2-3h). Traditional culturing methods are therefore often viewed as slow and 'out-dated', although they still deliver an internationally 'accepted' evidence-base. In contrast, molecular tools have the potential for rapid analysis and their operational utility and associated limitations and uncertainties should be assessed in light of their use for regulatory monitoring. Here we report on the recommendations from a series of international workshops, chaired by a UK Working Group (WG) comprised of scientists, regulators, policy makers and other stakeholders, which explored and interrogated both molecular (principally quantitative polymerase chain reaction [qPCR]) and culture-based tools for FIO monitoring under the European Bathing Water Directive. Through detailed analysis of policy implications, regulatory barriers, stakeholder engagement, and the needs of the end-user, the WG identified a series of key concerns that require critical appraisal before a potential shift from culture-based approaches to the employment of molecular biological methods for bathing water regulation could be justified.

    Artificial intelligence tools, fuzzy logic and neural networks were used to evaluate the potential of the behind pipe Mesaverde formation in BMG's Mancos formation wells. A fractal geostatistical mapping algorithm was also used to predict Mesaverde production. Additionally, a conventional geological study was conducted. To date one Mesaverde completion has been performed. The Janet No.3 Mesaverde completion was non-economic. Both the AI method and the geostatistical methods predicted the failure of the Janet No.3. The Gavilan No.1 in the Mesaverde was completed during the course of the study and was an extremely good well. This well was not included in the statistical dataset. The AI method predicted very good production while the fractal map predicted a poor producer.

    The relevance of noninvasive method for determining the blood sugar is caused by necessity of regular monitoring of glucose levels in diabetic patients blood. Traditional invasive method is painful, because it requires a finger pricking. Despite the active studies in the field of non-invasive medical diagnostics, to date the painless and inexpensive instrument for blood sugar control for personal use doesn't exist. It's possible to measure the concentration of glucose in the blood with help of spectrophotometry method. It consists of registering and analyzing the spectral characteristics of the radiation which missed, reflected or absorbed by the object. The authors proposed a measuring scheme for studying the spectral characteristics of the radiation, missed by earlobe. Ultra-violet, visible and near infrared spectral ranges are considered. The paper presents the description of construction and working principles of the proposed special retaining clip and results of experiment with real patient.

    Rapid changes in China over the past two decades have led to significant problems associated with population migration and changing social attitudes, including a growing sex industry and concurrent increases in STIs and HIV. This article reports results of an exploratory study of microbicide acceptability and readiness and current HIV prevention efforts among female sex workers in two rural and one urban town in Hainan and Guangxi Provinces in southern China. The study focused on these women’s knowledge and cultural understandings of options for protecting themselves from exposure to STIs and HIV, and the potential viability and acceptability of woman-initiated prevention methods. We report on ethnographic elicitation interviews conducted with women working within informal sex-work establishments (hotels, massage and beauty parlors, roadside restaurants, boarding houses). We discuss implications of these findings for further promotion of woman-initiated prevention methods such as microbicides and female condoms among female sex workers in China. PMID:17599276

    High-producing ruminants are fed high amounts of cereal grains, at the expense of dietary fiber, to meet their high energy demands. Grains consist mainly of starch, which is easily degraded in the rumen by microbial glycosidases, providing energy for rapid growth of rumen microbes and short-chain fatty acids (SCFA) as the main energy source for the host. Yet, low dietary fiber contents and the rapid accumulation of SCFA lead to rumen disorders in cattle. The chemical processing of grains has become increasingly important to confer their starch resistances against rumen microbial glycosidases, hence generating ruminally resistant starch (RRS). In ruminants, unlike monogastric species, the strategy of enhancing resistant starch is useful, not only in lowering the amount of carbohydrate substrates available for digestion in the upper gut sections, but also in enhancing the net hepatic glucose supply, which can be utilized by the host more efficiently than the hepatic gluconeogenesis of SCFA. The use of chemical methods to enhance the RRS of grains and the feeding of RRS face challenges in the practice; therefore, the present article attempts to summarize the most important achievements in the chemical processing methods used to generate RRS, and review advantages and challenges of feeding RRS to ruminants.

In ruminants, unlike monogastric species, the strategy of enhancing resistant starch is useful, not only in lowering the amount of carbohydrate substrates available for digestion in the upper gut sections, but also in enhancing the net hepatic glucose supply, which can be utilized by the host more efficiently than the hepatic gluconeogenesis of SCFA. The use of chemical methods to enhance the RRS of grains and the feeding of RRS face challenges in the practice; therefore, the present article attempts to summarize the most important achievements in the chemical processing methods used to generate RRS, and review advantages and challenges of feeding RRS to ruminants.

    Rare Earth based materials are increasingly being utilized in industrial and commercial practice. Large volume production of permanent magnet materials, Nd{sub 2}Fe{sub 14}B, SmCo{sub 5}, Sm{sub 2}Co{sub 17}, and rechargeable Ni/Metal Hydride batteries, LaNi{sub 5}, has increased the amount of rare earth based materials in the waste stream. Both for economic and environmental reasons, recycling and reuse of all materials is desirable. Unfortunately, the recycling methodology for these materials is in its infancy. In this paper the present {open_quotes}state of the art{close_quotes}, in recycling of rare earth based materials will be discussed. Additionally, new methods which alleviate many of the concerns of present aqueous based recycling technology will be presented.

    Concepts of medical treatment are constantly evolving and improving. This opportunity provides treatment with High Intensity Focused Ultrasound (HIFU). In Europe and Asia more than 10,000 patients with uterine fibroids have been successfully treated with HIFU technology until now. This is completely innovative technology for non-invasive extracorporeal treatment of benign and malignant tumors. Neighboring healthy tissue is not damaged. The main indication in HIFU-Center in Pleven is uterine fibroid. It is the most common solid tumor in the female pelvis and is the leading cause of hysterectomy. The methods of treatment are hysterectomy, myomectomy or embolization of uterine arteries. HIFU-methodology allows non-invasive treatment of fibroids disease. PMID:27025105

    Recent research is uncovering unexpected ways that glycans contribute to biology, as well as new strategies for combatting disease using approaches involving glycans. To make full use of glycans for clinical applications, we need more detailed information on the location, nature, and dynamics of glycan expression in vivo. Such studies require the use of specimens acquired directly from patients. Effective studies of clinical specimens require low-volume assays, high precision measurements, and the ability to process many samples. Assays using affinity reagents—lectins and glycan-binding antibodies—can meet these requirements, but further developments are needed to make the methods routine and effective. Recent advances in the use of glycan-binding proteins could meet that need. The advances involve improved determination of specificity using glycan arrays; the availability of databases for mining and analyzing glycan array data; lectin engineering methods; and the ability to quantitatively interpret lectin measurements. Here we describe many of the challenges and opportunities involved in the application of these new approaches to the study of biological samples. The new tools hold promise for developing methods to improve the outcomes of patients afflicted with diseases characterized by aberrant glycan expression. PMID:25727148

  19. Analysis of utility acid rain compliance plans: A discussion of issues and methods

    SciTech Connect

    Brick, S.

    1993-07-01

    Utility acid rain compliance plans have begun to roll into public utility commissions around the eastern half of the country. These plans typically represent the combined effort of utility staff and consultants, and have evolved since early drafts of Title IV of the Clean Air Act Amendments of 1990 (CAAA) began to circulate, several years back. The filings themselves often consist of many volumes of technical analysis, supporting documentation, and accompanying testimony. Hundreds of computer simulations are often presented and these, in turn, are underlain by hundreds of assumptions covering a staggering range of variables. Commissions usually have little time and few external resources with which to review and in some cases, preapprove proposed utility actions. There may be a tendency among commissions to forego a comprehensive review, approve utility plans as filed, and hope for the best. There are at least three important reasons, however, why this should not occur: (1) The magnitude of planned CAAA expenditures is large. (2) Preapproval, either formal or de facto, is becoming increasingly common. Although the approval of specific actions is certainly one outcome of the preapproval process, it should not be the sole or even principal outcome. The main focus of preapproval should involve defining an economic and institutional framework for how utilities, with input from regulators and the public, can best meet future customer needs. Done correctly, the preapproval process provides a meaningful, preexisting context which can be used to analyze outcomes. (3) Without adequate review market opportunities may be ignored and compliance costs increased unnecessarily. This article discusses the following topics in detail: CAAA Compliance Plan Review framework; Emission Reduction Alternatives: How Much is Enough?; Assumptions, Analytical Methods, and Evaluation Criteria of compliance plans; CAAA compliance costs and IRP. 2 figs., 3 tabs.

    The Long Term Resource Monitoring Program (LTRMP), an element of the multiagency partnership Upper Mississippi River Restoration-Environmental Management Program, has been monitoring fishes in the Upper Mississippi River System (UMRS) for over two decades, using scientific and highly standardized methods. Today, the LTRMP’s data assets represent one of the world’s largest and most extensive datasets on a great river. Methods and procedures used over the past two decades have been documented and have proven a key tool towards gaining data that are (a) scientifically valid, (b) comparable over time, and (c) comparable over space. These procedures manuals coordinate and standardize methods, procedures, and field behaviors in the execution of long-term monitoring, permitting the informed management and control of important sources of error actually under program control. As LTRMP databases have matured in scope and accumulated more years' worth of data, their utility in research and management in the UMRS basin has increased notably. To maximize their utility, data users need not only be aware of “how the data were collected,” as portrayed in the procedures manuals, but also “why the data were collected in the way they were, at the scales they were, and in the manner that they were.” Whereas the procedures manuals contribute information as to the “how” the data were gained, this document seeks to contribute information as to the “why.” As such, this document is intended to be a companion document to the procedures manuals. Herein, we present information on the rationale for monitoring nearly one-fifth of the entire North American freshwater fish fauna (representing the greatest freshwater fish diversity on the planet at temperate latitudes); strategies employed and their reasoning; and discussions on issues associated with the sampling design itself, data arising therefrom, and uses of those data in different contexts.

    The report summarizes the findings of a U.S. Department of Energy workshop on “Corrosion Issues of Relevance to the Yucca Mountain Waste Repository”. The workshop held on July 29-30, 2003 in Bethesda, MD and was co-sponsored by the Office of Basic Energy Sciences and Office of Civilian Radioactive Waste Management. The workshop focus was corrosion science relevant to long-term prediction of materials performance in hostile environments and with special focus on relevance to the permanent disposal of nuclear waste at the Yucca Mountain Repository. The culmination of the workshop is this report that identifies both generic and Yucca-Mountain-Project specific research opportunities in basic and applied topic areas. The research opportunities would be realized well after the U.S. Nuclear Regulatory Commission’s initial construction-authorization licensing process. At the workshop, twenty-three invited scientists deliberated on basic and applied science opportunities in corrosion science relevant to long-term prediction of damage accumulation by corrosive processes that affect materials performance.

    Desuperheater assembly experiences thermal cycling in operation by design. During power plant's start up, load change and shut down, thermal gradient is highest. Desuperheater should be able to handle rapid ramp up or ramp down of temperature in these operations. With "hump style" two nozzle desuperheater, cracks were appearing in the pipe after only few cycles of operation. From the field data, it was clear that desuperheater is not able to handle disproportionate thermal expansion happening in the assembly during temperature ramp up and ramp down in operation and leading to cracks appearing in the piping. Growth of thermal fatigue crack is influenced by several factors including geometry, severity of thermal stress and applied mechanical load. This paper seeks to determine cause of failure of two nozzle "hump style" desuperheater using Finite Element Method (FEM) simulation technique. Thermal stress simulation and fatigue life calculation were performed using commercial FEA software "ANSYS" [from Ansys Inc, USA]. Simulation result showed that very high thermal stress is developing in the region where cracks are seen in the field. From simulation results, it is also clear that variable thermal expansion of two nozzle studs is creating high stress at the water manifold junction. A simple and viable solution is suggested by increasing the length of the manifold which solved the cracking issues in the pipe.

    Presently around the globe there is a significant interest in using biomass for power generation as power generation from coal continues to raise environmental concerns. Biomass alone can be used for generation of power which can bring lot of environmental benefits. However the constraints of using biomass alone can include high investments costs for biomass feed systems and also uncertainty in the security of the feedstock supply due to seasonal variations and in most of the countries biomass is dispersed and the infrastructure for biomass supply is not well established. Alternatively cofiring biomass along with coal offer advantages like (a) reducing the issues related to biomass quality and buffers the system when there is insufficient feedstock quantity and (b) costs of adapting the existing coal power plants will be lower than building new systems dedicated only to biomass. However with the above said advantages there exists some technical constrains including low heating and energy density values, low bulk density, lower grindability index, higher moisture and ash content to successfully cofire biomass with coal. In order to successfully cofire biomass with coal, biomass feedstock specifications need to be established to direct pretreatment options that may include increasing the energy density, bulk density, stability during storage and grindability. Impacts on particle transport systems, flame stability, pollutant formation and boiler tube fouling/corrosion must also be minimized by setting feedstock specifications including composition and blend ratios if necessary. Some of these limitations can be overcome by using pretreatment methods. This paper discusses the impact of feedstock pretreatment methods like sizing, baling, pelletizing, briquetting, washing/leaching, torrefaction, torrefaction and pelletization and steam explosion in attainment of optimum feedstock characteristics to successfully cofire biomass with coal.

    Background Research on pressing health services and policy issues requires access to complete, accurate, and timely patient and organizational data. Aim This paper describes how administrative and health records (including electronic medical records) can be linked for comparative effectiveness and health services research. Materials and Methods We categorize the major agents (i.e., who owns and controls data and who carries out the data linkage) into three areas: (1) individual investigators; (2) government sponsored linked data bases; and (3) public–private partnerships that facilitate linkage of data owned by private organizations. We describe challenges that may be encountered in the linkage process, and the benefits of combining secondary databases with primary qualitative and quantitative sources. We use cancer care research to illustrate our points. Results To fill the gaps in the existing data infrastructure, additional steps are required to foster collaboration among institutions, researchers, and public and private components of the health care sector. Without such effort, independent researchers, governmental agencies, and nonprofit organizations are likely to continue building upon a fragmented and costly system with limited access. Discussion Without the development and support for emerging information technologies across multiple health care settings, the potential for data collected for clinical and transactional purposes to benefit the research community and, ultimately, the patient population may go unrealized. Conclusion The current environment is characterized by budget and technical challenges, but investments in data infrastructure are arguably cost-effective given the need to reform our health care system and to monitor the impact of health reform initiatives.

    1994-11-01

    This report is a review of current practices and policies in considering environmental externalities in the integrated resource planning and performance based regulation (IRP/PBR) process. The following issues are presented and examined: What are the pros and cons of treating environmental externalities in the IRP process? How are potential future environmental regulations being treated? Are externalities being qualitatively or quantitatively considered, or monetized? Are offsets being allowed? How are externality policies being coordinated among different levels and branches of governments? Should environmental externalities be considered in dispatching a utility`s existing resources? What are the procedures for addressing uncertainty in incorporating environmental externalities into IRP? How are externalities valued? What are other approaches to addressing environmental externalities. This report describes seven major approaches for addressing environmental externalities in the IRP process: qualitative treatment, weighting and ranking, cost of control, damage function, percentage adders, monetization by emission, and multiattribute trade-off analysis. The discussion includes a taxonomy of the full range of alternative methods for addressing environmental externalities, a summary of state PUC actions, the role of state laws, the debate on environmental adders, and the choice of methodologies. In addition, this report characterizes the interests of stakeholders such as the electric industry, fuel suppliers, energy consumers, governmental agencies, public interest groups, consultants, and others. It appears that the views, positions, and interests of these stakeholders are affected by their perceptions of the potential impacts on their economic interests or the viability of their position on environmental policy, by the societal perspective they take, and by the orientation of the analysts toward market competition and their respective accumulated expertise.

  10. Using Routinely Collected Hospital Data for Child Maltreatment Surveillance: Issues, Methods and Patterns

    PubMed Central

    2011-01-01

    Background International data on child maltreatment are largely derived from child protection agencies, and predominantly report only substantiated cases of child maltreatment. This approach underestimates the incidence of maltreatment and makes inter-jurisdictional comparisons difficult. There has been a growing recognition of the importance of health professionals in identifying, documenting and reporting suspected child maltreatment. This study aimed to describe the issues around case identification using coded morbidity data, outline methods for selecting and grouping relevant codes, and illustrate patterns of maltreatment identified. Methods A comprehensive review of the ICD-10-AM classification system was undertaken, including review of index terms, a free text search of tabular volumes, and a review of coding standards pertaining to child maltreatment coding. Identified codes were further categorised into maltreatment types including physical abuse, sexual abuse, emotional or psychological abuse, and neglect. Using these code groupings, one year of Australian hospitalisation data for children under 18 years of age was examined to quantify the proportion of patients identified and to explore the characteristics of cases assigned maltreatment-related codes. Results Less than 0.5% of children hospitalised in Australia between 2005 and 2006 had a maltreatment code assigned, almost 4% of children with a principal diagnosis of a mental and behavioural disorder and over 1% of children with an injury or poisoning as the principal diagnosis had a maltreatment code assigned. The patterns of children assigned with definitive T74 codes varied by sex and age group. For males selected as having a maltreatment-related presentation, physical abuse was most commonly coded (62.6% of maltreatment cases) while for females selected as having a maltreatment-related presentation, sexual abuse was the most commonly assigned form of maltreatment (52.9% of maltreatment cases

    Mechanism of four methods for removing hazardous heavy metal are detailed and compared-chemical/physical remediation, animal remediation, phytoremediation and microremediation with emphasis on bio-removal aspects. The latter two, namely the use of plants and microbes, are preferred because of their cost-effectiveness, environmental friendliness and fewer side effects. Also the obvious disadvantages of other alternatives are listed. In the future the application of genetic engineering or cell engineering to create an expected and ideal species would become popular and necessary. However, a concomitant and latent danger of genetic pollution is realized by a few persons. To cope with this potential harm, several suggestions are put forward including choosing self-pollinated plants, creating infertile polyploid species and carefully selecting easy-controlled microbe species. Bravely, the authors point out that current investigation of noncrop hyperaccumulators is of little significance in application. Pragmatic development in the future should be crop hyperaccumulators (newly termed as "cropaccumulators") by transgenic or symbiotic approach. Considering no effective plan has been put forward by others about concrete steps of applying a hyperaccumulator to practice, the authors bring forward a set of universal procedures, which is novel, tentative and adaptive to evaluate hyperaccumulators' feasibility before large-scale commercialization.

    PubMed

    1998-01-01

    For the first time in its history, this journal assumes the unusual form of a monograph: the issue is dedicated to the problems of research methodology, as it applies to the nursing context and activities. The purpose and the contents which are developed along the eight "chapters" can be summarised as follows: 1. It is widely recognised that health care systems are undergoing a profound and rapid transformation phase, which is obviously affecting the nursing profession and roles. To minimize the very real risk of being passive observers of the changes, a propositive strategy based on diffuse and intense research activities (aiming at describing, anticipating, assessing, experimenting changes and hypotheses) appears to be a priority choice (besides the more classical and needed institutional battles and arrangements). 2. Since its very beginning (back 15 years ago), this journal had adopted among its main objectives and distinctive features, the promotion of a research oriented mentality in a profession which (mainly, but not exclusively in Italy) has been characterised more in terms of executive and basically dependent tasks. The key thesis all over the years has been that, to be relevant for the whole profession, research should not be conceived as a separate or élite area of interest but it should be as close as possible (in its scope and methods), to the routine activities of the majority of the nurses. 3. The years long experience has produced (both through the materials which have been published, and the training initiatives which the Rdl has promoted) an important body of concepts and suggestions, which appear to be possibly useful to integrate the existing standard literature dedicated to research methods and designs. 4. The structure chosen for the overall organisation of the issue tries to comply to this "experimental" background: after a first part focused on the close articulation between the conceptual and historical specificities of nursing research

    Guinan Jr., John J.

    2014-01-01

    As studies of the olivocochlear (OC) efferent system have matured, issues have been identified that need to be taken into account in the design of new studies and in the interpretation of existing work. The need for high signal-to-noise ratios (SNRs), multiple alternations of conditions, and avoiding middle-ear-muscle activation have been previously highlighted. Less well-known issues include: Contralateral medial OC (MOC) effects may not be good proxies for ipsilateral (ipsi) MOC effects; MOC-induced changes in otoacoustic emissions (OAEs) may not accurately show MOC-induced changes in auditory-nerve (AN) responses; measuring OAE differences from before to after psychophysical trials yields the transient OAE change but not tonic MOC activation; tonic MOC activation may be measurable by several techniques including by OAE differences in trials in which the subject’s judgment was correct vs. trials that were incorrect; SNRs can be preserved by Bootstrap statistical tests; differences in task difficulty may outweigh differences in subject attention; lateral efferent effects are little understood and may be tied to MOC effects; to assess whether MOC strength predicts protection from acoustic trauma, prospective tests in humans are needed.

    Attribute generation for discrete choice experiments (DCEs) is often poorly reported, and it is unclear whether this element of research is conducted rigorously. This paper explores issues associated with developing attributes for DCEs and contrasts different qualitative approaches. The paper draws on eight studies, four developed attributes for measures, and four developed attributes for more ad hoc policy questions. Issues that have become apparent through these studies include the following: the theoretical framework for random utility theory and the need for attributes that are neither too close to the latent construct nor too intrinsic to people's personality; the need to think about attribute development as a two-stage process involving conceptual development followed by refinement of language to convey the intended meaning; and the difficulty in resolving tensions inherent in the reductiveness of condensing complex and nuanced qualitative findings into precise terms. The comparison of alternative qualitative approaches suggests that the nature of data collection will depend both on the characteristics of the question (its sensitivity, for example) and the availability of existing qualitative information. An iterative, constant comparative approach to analysis is recommended. Finally, the paper provides a series of recommendations for improving the reporting of this element of DCE studies.

    Nonprescription drug therapy is tightly woven into the fabric of American health care. Market forces are expected to contribute to significant expansion of nonprescription drug use. Consumers place high value on nonprescription drug therapy; however, self-medicating patients frequently need assistance from a learned intermediary to assure optimal integration of nonprescription drug therapy into the total care regimen. Pharmacist-assisted self-care holds vast potential to serve the public interest, but this expanded practice role will require higher levels of professional practice commitment by American pharmacy. That commitment must be supported by practice-relevant, competency-based, patient-centered college and school of pharmacy curricula and continuing education that assures perpetual intellectual proficiency in nonprescription drug pharmacotherapy. That knowledge and competency must be integrated holistically into the total mix of patient comorbidity and polypharmacy. The pharmacist-assisted self-care business and professional practice model must be further facilitated by state and national pharmacy organizations, chain and independent community pharmacy, pharmacy wholesalers, and others. Consumers await expanded and differentiated pharmacy-based, pharmacist-provided medication therapy management services focused on the safe, appropriate, and effective selection, use, and monitoring of nonprescription drugs therapy.

However, use of "big data" mining and discovery techniques has also raised ethical issues such as how to balance privacy and autonomy with the wider public benefits of data sharing. Furthermore, electronic data are being increasingly used to identify individual characteristics, which can be useful for clinical prediction and management, but were not previously disclosed to a clinician. This process in computer parlance is called electronic phenotyping, and has a number of ethical implications. Using the Belmont Report's principles of respect for persons, beneficence, and justice as a framework, we examined the ethical issues posed by electronic phenotyping. Ethical issues identified include the ability of the patient to consent for the use of their information, the ability to suppress pediatric information, ensuring that the potential benefits justify the risks of harm to patients, and acknowledging that the clinician's biases or stereotypes, conscious or unintended, may become a factor in the therapeutic interaction. We illustrate these issues with two vignettes, using the person characteristic of gender minority status (i.e., transgender identity) and health history characteristic of substance abuse. Data mining has the potential to uncover patient characteristics previously obscured, which can provide clinicians with beneficial clinical information. Hence, ethical guidelines must be updated to ensure that electronic phenotyping supports the principles of respect for persons, beneficence, and justice. PMID:27534587

    The impact of video game playing on cognitive abilities has been the focus of numerous studies over the last 10 years. Some cross-sectional comparisons indicate the cognitive advantages of video game players (VGPs) over non-players (NVGPs) and the benefits of video game trainings, while others fail to replicate these findings. Though there is an ongoing discussion over methodological practices and their impact on observable effects, some elementary issues, such as the representativeness of recruited VGP groups and lack of genre differentiation have not yet been widely addressed. In this article we present objective and declarative gameplay time data gathered from large samples in order to illustrate how playtime is distributed over VGP populations. The implications of this data are then discussed in the context of previous studies in the field. We also argue in favor of differentiating video games based on their genre when recruiting study samples, as this form of classification reflects the core mechanics that they utilize and therefore provides a measure of insight into what cognitive functions are likely to be engaged most. Additionally, we present the Covert Video Game Experience Questionnaire as an example of how this sort of classification can be applied during the recruitment process. PMID:26483717

    In this study, we assessed the impact of sampling method on the results of fish ectoparasite studies. Common roach Rutilus rutilus were sampled from the same gravel pit in the River Dyje flood plain (Czech Republic) using 3 different sampling methods, i.e. electrofishing, beach seining and gill-netting, and were examined for ectoparasites. Not only did fish caught by electrofishing have more of the most abundant parasites (Trichodina spp., Gyrodactylus spp.) than those caught by beach seining or gill-netting, they also had relatively rich parasite infracommunities, resulting in a significantly different assemblage composition, presumably as parasites were lost through handling and 'manipulation' in the net. Based on this, we recommend electrofishing as the most suitable method to sample fish for parasite community studies, as data from fish caught with gill-nets and beach seines will provide a biased picture of the ectoparasite community, underestimating ectoparasite abundance and infracommunity species richness.

    Global concern about the environment is increasing, and the People's Republic of China (PRC) is not immune from such concerns. The Chinese face issues similar to those of many other developing nations. The US Department of Energy is particularly interested in national and world pollution issues, especially those that may infringe on other countries' economic growth and development. The DOE is also interested in any opportunities that might exist for US technical assistance and equipment in combating environmental problems. Our studies of articles in the China Daily, and English-language daily newspaper published by the Chinese government, show that population, pollution, and energy are major concerns of the Chinese Communist Party. Thus this report emphasizes the official Chinese government view. Supporting data were also obtained from other sources. Regardless of the severity of their various environmental problems, the Chinese will only try to remedy those problems with the greatest negative effects on its developing economy. They will be looking for foreign assistance, financial and informational, to help implement solutions. With the Chinese government seeking assistance, the United States has an opportunity to export basic technical information, especially in the areas of pollution control and monitoring, oil exploration methods, oil drilling technology, water and sewage treatment procedures, hazardous waste and nuclear waste handling techniques, and nuclear power plant safety procedures. In those areas the US has expertise and extensive technical experience, and by exporting the technologies the US would benefit both economically and politically. 59 refs., 3 figs.

  20. Soil Water Content Assessment: Critical Issues Concerning the Operational Application of the Triangle Method

    2015-01-01

    Knowledge of soil water content plays a key role in water management efforts to improve irrigation efficiency. Among the indirect estimation methods of soil water content via Earth Observation data is the triangle method, used to analyze optical and thermal features because these are primarily controlled by water content within the near-surface evaporation layer and root zone in bare and vegetated soils. Although the soil-vegetation-atmosphere transfer theory describes the ongoing processes, theoretical models reveal limits for operational use. When applying simplified empirical formulations, meteorological forcing could be replaced with alternative variables when the above-canopy temperature is unknown, to mitigate the effects of calibration inaccuracies or to account for the temporal admittance of the soil. However, if applied over a limited area, a characterization of both dry and wet edges could not be properly achieved; thus, a multi-temporal analysis can be exploited to include outer extremes in soil water content. A diachronic empirical approach introduces the need to assume a constancy of other meteorological forcing variables that control thermal features. Airborne images were acquired on a Sicilian vineyard during most of an entire irrigation period (fruit-set to ripening stages, vintage 2008), during which in situ soil water content was measured to set up the triangle method. Within this framework, we tested the triangle method by employing alternative thermal forcing. The results were inaccurate when air temperature at airborne acquisition was employed. Sonic and aerodynamic air temperatures confirmed and partially explained the limits of simultaneous meteorological forcing, and the use of proxy variables improved model accuracy. The analysis indicates that high spatial resolution does not necessarily imply higher accuracies. PMID:25808771

    2016-05-01

    This study aims to increase the inactivation efficiency of CO2 against Escherichia coli under mild conditions to facilitate the application of pressurized CO2 technology in water disinfection. Based on an aerating-cycling apparatus, three different treatment methods (continuous aeration, continuous reflux, and simultaneous aeration and reflux) were compared for the same temperature, pressure (0.3-0.7MPa), initial concentration, and exposure time (25min). The simultaneous aeration and reflux treatment (combined method) was shown to be the best method under optimum conditions, which were determined to be 0.7MPa, room temperature, and an exposure time of 10min. This treatment achieved 5.1-log reduction after 25min of treatment at the pressure of 0.3MPa and 5.73-log reduction after 10min at 0.7MPa. Log reductions of 4.4 and 5.0 occurred at the end of continuous aeration and continuous reflux treatments at 0.7MPa, respectively. Scanning electron microscopy (SEM) images suggested that cells were ruptured after the simultaneous aeration and reflux treatment and the continuous reflux treatment. The increase of the solubilization rate of CO2 due to intense hydraulic conditions led to a rapid inactivation effect. It was found that the reduction of intracellular pH caused by CO2 led to a more lethal bactericidal effect. PMID:27155435

  3. Gulliver's Eggs: Why Methods are not an Issue of Qualitative Research in Cultural Psychology.

    PubMed

    2015-06-01

    The future of qualitative methods regards the kind of object cultural psychology is interested and the kind of questions it can ask. I propose that the object should be experiencing, understood as a complex whole, consisting of lived-by action and counter-action, that is contextual inter-action with the world in the form of an experiencing subject and otherness. The kind of questions cultural psychology can ask is instead related to the epistemological status attributed to both researcher and participant. Probably few scholars such as Vygotsky, Piaget and Lewin understood to what extent experiencing is always changing, because the relationship between mind, alterity and culture is co-generative. This also implies a relativization and a decentralization of the psychology's perspective. Finally, I provide some examples from the history of psychology and some suggestions to work at the level of such complexity by using methods that can work with complex objects such as products of human activity (e.g., art, literature, architecture, etc.).

    Knowledge of the right atrial pressure (RAP) values is critical to ascertain the existence of a state of hemodynamic congestion, irrespective of the possible presence of signs and symptoms of clinical congestion and cardiac overload that can be lacking in some conditions of concealed or clinically misleading cardiac decompensation. In addition, a more reliable estimate of RAP would make it possible to determine more accurately also the systolic pulmonary arterial pressure with the only echocardiographic methods. The authors briefly illustrate some of the criteria that have been implemented to obtain a non-invasive RAP estimate, some of which have been approved by current guidelines and others are still awaiting official endorsement from the Scientific Societies of Cardiology. There is a representation of the sometimes opposing views of researchers who have studied the problem, and the prospects for development of new diagnostic criteria are outlined, in particular those derived from the matched use of two- and three-dimensional echocardiographic parameters.

    This Long Term Planning graphic was created from a mosaic of navigation camera images overlain by a polar coordinate grid with the center point as Opportunity's original landing site. The blue dots represent the rover position at various locations.

    The red dots represent the center points of the target areas for the instruments on the rover mast (the panoramic camera and miniature thermal emission spectrometer). Opportunity visited Stone Mountain on Feb. 5. Stone Mountain was named after the southernmost point of the Appalachian Mountains outside of Atlanta, Ga. On Earth, Stone Mountain is the last big mountain before the Piedmont flatlands, and on Mars, Stone Mountain is at one end of Opportunity Ledge. El Capitan is a target of interest on Mars named after the second highest peak in Texas in Guadaloupe National Park, which is one of the most visited outcrops in the United States by geologists. It has been a training ground for students and professional geologists to understand what the layering means in relation to the formation of Earth, and scientists will study this prominent point of Opportunity Ledge to understand what the layering means on Mars.

    The yellow lines show the midpoint where the panoramic camera has swept and will sweep a 120-degree area from the three waypoints on the tour of the outcrop. Imagine a fan-shaped wedge from left to right of the yellow line.

    The white contour lines are one meter apart, and each drive has been roughly about 2-3 meters in length over the last few sols. The large white blocks are dropouts in the navigation camera data.

    Opportunity is driving along and taking a photographic panorama of the entire outcrop. Scientists will stitch together these images and use the new mosaic as a 'base map' to decide on geology targets of interest for a more detailed study of the outcrop using the instruments on the robotic arm. Once scientists choose their targets of interest, they plan to study the outcrop for roughly five to

    2010-12-01

    Australia is going through a significant period of water reform. The increasing demand for water for cities, industries, irrigation and the environment, and the current prolonged drought in southern Australia and predictions of a drier future are putting immense pressure on water resources. The management challenge in Australia is compounded by the low runoff coefficient and high river flow variability in Australia compared to elsewhere in the world. To underpin water planning and management, several large modelling studies to assess historical and future water availability were recently completed. This paper will discuss the different methods that can be used to estimate future water availability. Simple rules of thumb based on climate elasticities of streamflow and Budyko-type energy and water balance equations can be used for data limited regions or where only mean annual estimates are required. More detailed studies will combine projections from global and regional climate models, methods to downscale climate model projections to catchment-scale climate series and hydrological models that properly consider potential changes in dominant hydrological processes in a warmer, drier and higher CO2 environment. This paper will show that the largest uncertainty in predicting future water availability is in the projections of regional climate, in particular rainfall. For example, there is little agreement between the different global climate models on the direction of change in rainfall in the northern half of continental Australia. However, over the highly populated and important agricultural regions of south-eastern Australia, a large majority of climate models indicate a drier future. The median result from hydrological modelling with future climate projections from more than 20 global climate models indicate that averaged across south-eastern Australia, there will be 10 percent less water (range of result from -30 percent to +10 percent) for a 1oC global warming

  9. A Method for and Issues Associated with the Determination of Space Suit Joint Requirements

    NASA Technical Reports Server (NTRS)

    Matty, Jennifer E.; Aitchison, Lindsay

    2009-01-01

    In the design of a new space suit it is necessary to have requirements that define what mobility space suit joints should be capable of achieving in both a system and at the component level. NASA elected to divide mobility into its constituent parts-range of motion (ROM) and torque- in an effort to develop clean design requirements that limit subject performance bias and are easily verified. Unfortunately, the measurement of mobility can be difficult to obtain. Current technologies, such as the Vicon motion capture system, allow for the relatively easy benchmarking of range of motion (ROM) for a wide array of space suit systems. The ROM evaluations require subjects in the suit to accurately evaluate the ranges humans can achieve in the suit. However, when it comes to torque, there are significant challenges for both benchmarking current performance and writing requirements for future suits. This is reflected in the fact that torque definitions have been applied to very few types of space suits and with limited success in defining all the joints accurately. This paper discussed the advantages and disadvantages to historical joint torque evaluation methods, describes more recent efforts directed at benchmarking joint torques of prototype space suits, and provides an outline for how NASA intends to address joint torque in design requirements for the Constellation Space Suit System (CSSS).

    Parents need information and skills to meet the demands of mediating connected technology in their homes. Parents' methods and motivations for learning to protect children from digital risks were reported through a survey. This study explores relationships between information seeking, parents' concerns, risks children have experienced, and access to connected devices, in addition to the use and satisfaction of various digital safety resources. Three types of information-seeking behavior were identified: (a) protective information seeking, to protect children from being confronted with harmful content; (b) problem-solving information seeking, to help children who have been negatively affected by connected technology; and (c) attentive learning, by attending to media resources passively encountered on this topic. Friends and family are the dominant source of digital safety information, followed by presentations and the Internet. Parents' top concerns for their children using connected technology were accidental exposure to pornography, and sexual content in Internet-based entertainment. Higher numbers of risks experienced by children were positively associated with parents' problem-solving information seeking and level of attentive learning. Parents who were more concerned exhibited more problem-solving information seeking; but despite the high level of concern for children's safety online, 65 percent of parents seek information on this subject less than twice per year. Children have access to a mean of five connected devices at home; a higher number of devices was correlated with increased risks experienced by children, but was not associated with increased concern or information seeking from parents.

    As part of the NRC-sponsored program to study the implications of Generic Issue 57, Effects of Fire Protection System Actuation on Safety-Related Equipment,'' a subtask was performed to evaluate the applicability of formal decision analysis methods to generic issues cost/benefit-type decisions and to apply these methods to the GI-57 results. In this report, the numerical results obtained from the analysis of three plants (two PWRs and one BWR) as developed in the technical resolution program for GI-57 were studied. For each plant, these results included a calculation of the person-REM averted due to various accident scenarios and various proposed modifications to mitigate the accident scenarios identified. These results were recomputed to break out the benefit in terms of contributions due to random event scenarios, fire event scenarios, and seismic event scenarios. Furthermore, the benefits associated with risk (in terms of person-REM) averted from earthquakes at three different seismic ground motion levels were separately considered. Given this data, formal decision methodologies involving decision trees, value functions, and utility functions were applied to this basic data. It is shown that the formal decision methodology can be applied at several different levels. Examples are given in which the decision between several retrofits is changed from that resulting from a simple cost/benefit-ratio criterion by virtue of the decision-makinger's expressed (and assumed) preferences.

    Indian is one of the largest potential markets for private power. Shri P.V. Rangayya Naidu, Minister of State for Power, details the opportunities his country offers. Electricity plays a key role in the Indian economy, and its consumption is an indicator of productivity and growth. Development in the power sector has been given a high priority. Despite remarkable growth, India still faces power shortages. After rigorous review of the power sector the Government of India (GOI) is doubtful of reaching new capacity goals. It has therefore become imperature to accelerate capacity growth. To bridge the power gap the GOI is encouraging private participation. In 1991 the GOI had opened its doors to both foreign and domestic investors. Since then the legal, financial, and administrative framework has been modified to suit investors and developers. The present economic reforms pave the way for a smooth transition.

    The Working Party on International Nuclear Data Evaluation Cooperation (WPEC) of the Nuclear Science Committee under the Nuclear Energy Agency (NEA/OECD) established a Subgroup (called “Subgroup 33”) in 2009 on “Methods and issues for the combined use of integral experiments and covariance data.” The first stage was devoted to producing the description of different adjustment methodologies and assessing their merits. A detailed document related to this first stage has been issued. Nine leading organizations (often with a long and recognized expertise in the field) have contributed: ANL, CEA, INL, IPPE, JAEA, JSI, NRG, IRSN and ORNL. In the second stage a practical benchmark exercise was defined in order to test the reliability of the nuclear data adjustment methodology. A comparison of the results obtained by the participants and major lessons learned in the exercise are discussed in the present paper that summarizes individual contributions which often include several original developments not reported separately. The paper provides the analysis of the most important results of the adjustment of the main nuclear data of 11 major isotopes in a 33-group energy structure. This benchmark exercise was based on a set of 20 well defined integral parameters from 7 fast assembly experiments. The exercise showed that using a common shared set of integral experiments but different starting evaluated libraries and/or different covariance matrices, there is a good convergence of trends for adjustments. Moreover, a significant reduction of the original uncertainties is often observed. Using the a–posteriori covariance data, there is a strong reduction of the uncertainties of integral parameters for reference reactor designs, mainly due to the new correlations in the a–posteriori covariance matrix. Furthermore, criteria have been proposed and applied to verify the consistency of differential and integral data used in the adjustment. Finally, recommendations are given

    The Working Party on International Nuclear Data Evaluation Cooperation (WPEC) of the Nuclear Science Committee under the Nuclear Energy Agency (NEA/OECD) established a Subgroup (called "Subgroup 33") in 2009 on "Methods and issues for the combined use of integral experiments and covariance data." The first stage was devoted to producing the description of different adjustment methodologies and assessing their merits. A detailed document related to this first stage has been issued. Nine leading organizations (often with a long and recognized expertise in the field) have contributed: ANL, CEA, INL, IPPE, JAEA, JSI, NRG, IRSN and ORNL. In the second stage a practical benchmark exercise was defined in order to test the reliability of the nuclear data adjustment methodology. A comparison of the results obtained by the participants and major lessons learned in the exercise are discussed in the present paper that summarizes individual contributions which often include several original developments not reported separately. The paper provides the analysis of the most important results of the adjustment of the main nuclear data of 11 major isotopes in a 33-group energy structure. This benchmark exercise was based on a set of 20 well defined integral parameters from 7 fast assembly experiments. The exercise showed that using a common shared set of integral experiments but different starting evaluated libraries and/or different covariance matrices, there is a good convergence of trends for adjustments. Moreover, a significant reduction of the original uncertainties is often observed. Using the a-posteriori covariance data, there is a strong reduction of the uncertainties of integral parameters for reference reactor designs, mainly due to the new correlations in the a-posteriori covariance matrix. Furthermore, criteria have been proposed and applied to verify the consistency of differential and integral data used in the adjustment. Finally, recommendations are given for an

    Objectives. We sought to outline the framework and methods used by the World Health Organization (WHO) STEPwise approach to noncommunicable disease (NCD) surveillance (STEPS), describe the development and current status, and discuss strengths, limitations, and future directions of STEPS surveillance. Methods. STEPS is a WHO-developed, standardized but flexible framework for countries to monitor the main NCD risk factors through questionnaire assessment and physical and biochemical measurements. It is coordinated by national authorities of the implementing country. The STEPS surveys are generally household-based and interviewer-administered, with scientifically selected samples of around 5000 participants. Results. To date, 122 countries across all 6 WHO regions have completed data collection for STEPS or STEPS-aligned surveys. Conclusions. STEPS data are being used to inform NCD policies and track risk-factor trends. Future priorities include strengthening these linkages from data to action on NCDs at the country level, and continuing to develop STEPS’ capacities to enable a regular and continuous cycle of risk-factor surveillance worldwide.

    An important step in advancing global health through informatics is to understand how systems support health professionals to deliver improved services to patients. Studies in several countries have highlighted the potential for clinical information systems to change patterns of work and communication, and in particular have raised concerns that they reduce nurses’ time in direct care. However measuring the effects of systems on work is challenging and comparisons across studies have been hindered by a lack of standardised definitions and measurement tools. This paper describes the Work Observation Method by Activity Time (WOMBAT) technique version 1.0 and the ways in which the data generated can describe different aspects of health professionals’ work. In 2011 a revised WOMBAT version 2.0 was developed specifically to facilitate its use by research teams in different countries. The new features provide opportunities for international comparative studies of nurses’ work to be conducted. PMID:24199139

  2. Development of a national Flash flood warning system in France using the AIGA method: first results and main issues

    Developing a national flash flood (FF) warning system is an ambitious and difficult task. On one hand it rises huge expectations from exposed populations and authorities since induced damages are considerable (ie 20 casualties in the recent October 2015 flood at the French Riviera). But on the other hand, many practical and scientific issues have to be addressed and limitations should be clearly stated. The FF warning system to be implemented by 2016 in France by the SCHAPI (French national service in charge of flood forecasting) will be based on a discharge-threshold flood warning method called AIGA (Javelle et al. 2014). The AIGA method has been experimented in real time in the south of France in the RHYTMME project (http://rhytmme.irstea.fr). It consists in comparing discharges generated by a simple conceptual hourly hydrologic model run at a 1-km² resolution to reference flood quantiles of different return periods, at any point along the river network. The hydrologic model ingests operational rainfall radar-gauge products from Météo-France. Model calibration was based on ~700 hydrometric stations over the 2002-2015 period and then hourly discharges were computed at ~76 000 catchment outlets, with areas ranging from 10 to 3 500 km², over the last 19 years. This product makes it possible to calculate reference flood quantiles at each outlet. The on-going evaluation of the FF warnings is currently made at two levels: in a 'classical' way, using discharges available at the hydrometric stations, but also in a more 'exploratory' way, by comparing past flood reports and warnings issued by the system over the 76 000 catchment outlets. The interest of the last method is that it better fit the system objectives since it is designed to monitor small ungauged catchments. Javelle, P., Demargne, J., Defrance, D, .Pansu, J, .Arnaud, P.

    Background Recently there has been increasing focus on monitoring pollinating insects, due to concerns about their declines, and interest in the role of volunteers in monitoring pollinators, particularly bumblebees, via citizen science. Methodology / Principal Findings The Big Bumblebee Discovery was a one-year citizen science project run by a partnership of EDF Energy, the British Science Association and the Centre for Ecology & Hydrology which sought to assess the influence of the landscape at multiple scales on the diversity and abundance of bumblebees. Timed counts of bumblebees (Bombus spp.; identified to six colour groups) visiting focal plants of lavender (Lavendula spp.) were carried out by about 13 000 primary school children (7–11 years old) from over 4000 schools across the UK. 3948 reports were received totalling 26 868 bumblebees. We found that while the wider landscape type had no significant effect on reported bumblebee abundance, the local proximity to flowers had a significant effect (fewer bumblebees where other flowers were reported to be >5m away from the focal plant). However, the rate of mis-identifcation, revealed by photographs uploaded by participants and a photo-based quiz, was high. Conclusions / Significance Our citizen science results support recent research on the importance of local flocal resources on pollinator abundance. Timed counts of insects visiting a lure plant is potentially an effective approach for standardised pollinator monitoring, engaging a large number of participants with a simple protocol. However, the relatively high rate of mis-identifications (compared to reports from previous pollinator citizen science projects) highlights the importance of investing in resources to train volunteers. Also, to be a scientifically valid method for enquiry, citizen science data needs to be sufficiently high quality, so receiving supporting evidence (such as photographs) would allow this to be tested and for records to be verified

    A correlation method to predict pressures induced on an infinite plate by a jet issuing from the plate into a subsonic free stream was developed. The complete method consists of an analytical method which models the blockage and entrainment properties of the jet and a correlation which accounts for the effects of separation. The method was developed for jet velocity ratios up to ten and for radial distances up to five diameters from the jet. Correlation curves and data comparisons are presented for jets issuing normally from a flat plate with velocity ratios one to twelve. Also, a list of references which deal with jets in a crossflow is presented.

    Inverse problems in electromagnetics have a long history and have stimulated exciting research over many decades. New applications and solution methods are still emerging, providing a rich source of challenging topics for further investigation. The purpose of this special issue is to combine descriptions of several such developments that are expected to have the potential to fundamentally fuel new research, and to provide an overview of novel methods and applications for electromagnetic inverse problems. There have been several special sections published in Inverse Problems over the last decade addressing fully, or partly, electromagnetic inverse problems. Examples are: Electromagnetic imaging and inversion of the Earth's subsurface (Guest Editors: D Lesselier and T Habashy) October 2000 Testing inversion algorithms against experimental data (Guest Editors: K Belkebir and M Saillard) December 2001 Electromagnetic and ultrasonic nondestructive evaluation (Guest Editors: D Lesselier and J Bowler) December 2002 Electromagnetic characterization of buried obstacles (Guest Editors: D Lesselier and W C Chew) December 2004 Testing inversion algorithms against experimental data: inhomogeneous targets (Guest Editors: K Belkebir and M Saillard) December 2005 Testing inversion algorithms against experimental data: 3D targets (Guest Editors: A Litman and L Crocco) February 2009 In a certain sense, the current issue can be understood as a continuation of this series of special sections on electromagnetic inverse problems. On the other hand, its focus is intended to be more general than previous ones. Instead of trying to cover a well-defined, somewhat specialized research topic as completely as possible, this issue aims to show the broad range of techniques and applications that are relevant to electromagnetic imaging nowadays, which may serve as a source of inspiration and encouragement for all those entering this active and rapidly developing research area. Also, the

    Engineering design is known as an answer to an ill-defined problem. As any answer to an ill-defined problem, it can never be completely right or absolutely wrong. The methods that universities use to teach engineering design, as a consequence of this, suffer from the same fate. However, the accumulated experience with the 'chalk and talk' teaching tradition has led to a reality in which the employers of fresh graduates are not happy with the engineers they are getting. Part of their complaints are related with the inability of recently graduate engineers to work in problems where the boundaries are not well defined, are interdisciplinary, require the use of effective communication and integrate non-technical issues. These skills are mostly absent from traditional engineering curricula. This paper demonstrates the implementation of engineering design perspectives enhancing some of the aforementioned skills in a traditional mechanical engineering curriculum. It emphasises in particular a design project that is tackled in a sequence of conventional courses with a focus that depends on the course objectives and disciplinary domain. This transdisciplinary design project conveys the idea (and effectively implements it concurrently) that design is multidisciplinary.

    In-vehicle information systems (IVIS) can be controlled by the user via direct or indirect input devices. In order to develop the next generation of usable IVIS, designers need to be able to evaluate and understand the usability issues associated with these two input types. The aim of this study was to investigate the effectiveness of a set of empirical usability evaluation methods for identifying important usability issues and distinguishing between the IVIS input devices. A number of usability issues were identified and their causal factors have been explored. These were related to the input type, the structure of the menu/tasks and hardware issues. In particular, the translation between inputs and on-screen actions and a lack of visual feedback for menu navigation resulted in lower levels of usability for the indirect device. This information will be useful in informing the design of new IVIS, with improved usability. STATEMENT OF RELEVANCE: This paper examines the use of empirical methods for distinguishing between direct and indirect IVIS input devices and identifying usability issues. Results have shown that the characteristics of indirect input devices produce more serious usability issues, compared with direct devices and can have a negative effect on the driver-vehicle interaction.

  16. Making the case for STEM integration at the upper elementary level: A mixed methods exploration of opportunity to learn math and science, teachers' efficacy and students' attitudes

    NASA Astrophysics Data System (ADS)

    Miller, Brianna M.

    Student achievement in science and math has been linked to per capita gross domestic product (GDP) growth propagating the belief that science, technology, engineering, and math (STEM) education is an important factor in economic prosperity. However, The No Child Left Behind Act of 2001 (NCLB), favors math over science, positioning the subjects as competitors rather than collaborators. Additionally, NCLB focuses almost exclusively on the cognitive outcome of students' achievement with the affective outcome of students' attitudes being nearly ignored. Positive attitudes toward science and math early on are essential for subsequent and cumulative decisions students make in taking courses, choosing majors, and pursuing careers. Positioning students' attitudes as a desirable educational outcome comparable to students' achievement is an emerging goal in the literature. Using the case of one school district in south-central Pennsylvania with three elementary schools, 15 upper elementary teachers, and 361 students, the purpose of this study was to better understand influences on upper elementary students' attitudes toward STEM (SA) subjects and careers. The study aimed to explore two influences on SA, opportunity to learn (OTL) and teacher's efficacy (TE), in the comparative contexts of math and science. The studied employed a mixed methods convergent design in which five data sets from four sources were collected over three phases to triangulate three constructs: OTL, TE, and SA. The goal of the study was to offer recommendations to the case school district for enhancing OTL, TE, and thus SA. Findings regarding OTL revealed that the opportunity to learn science was lower than math. Finding regarding TE revealed that outcome expectancy was lower than personal teaching efficacy in both science and math; and, teachers had low STEM career awareness, STEM integration, and technology use. Findings regarding SA revealed a lower perceived usefulness of science compared to math

    Chlorine dioxide gas and vaporous hydrogen peroxide sterilant have been used in the cleanup of building interiors contaminated with spores of Bacillus anthracis. A systematic study, in collaboration with the U.S. Environmental Protection Agency, was jointly undertaken by the U.S. Army-Edgewood Chemical Biological Center to determine the sporicidal efficacies of these two fumigants on six building structural materials: carpet, ceiling tile, unpainted cinder block, painted I-beam steel, painted wallboard, and unpainted pinewood. Critical issues related to high-throughput sample processing and spore recovery from porous and nonporous surfaces included (i) the extraction of spores from complex building materials, (ii) the effects of titer challenge levels on fumigant efficacy, and (iii) the impact of bioburden inclusion on spore recovery from surfaces and spore inactivation. Small pieces (1.3 by 1.3 cm of carpet, ceiling tile, wallboard, I-beam steel, and pinewood and 2.5 by 1.3 cm for cinder block) of the materials were inoculated with an aliquot of 50 μl containing the target number (1 × 106, 1 × 107, or 1 × 108) of avirulent spores of B. anthracis NNR1Δ1. The aliquot was dried overnight in a biosafety cabinet, and the spores were extracted by a combination of a 10-min sonication and a 2-min vortexing using 0.5% buffered peptone water as the recovery medium. No statistically significant drop in the kill efficacies of the fumigants was observed when the spore challenge level was increased from 6 log units to 8 log units, even though a general trend toward inhibition of fumigant efficacy was evident. The organic burden (0 to 5%) in the spore inoculum resulted in a statistically significant drop in spore recovery (at the 2 or 5% level). The effect on spore killing was a function of the organic bioburden amount and the material type. In summary, a high-throughput quantitative method was developed for determining the efficacies of fumigants, and the spore recoveries

    Inadequate turbomachine interface design can rapidly degrade system performance, yet provide great opportunity for improvements. Engineered coatings of seals and bearing interfaces are major issues in the operational life of power systems. Coatings, films, and combined use of both metals and ceramics play a major role in maintaining component life. Interface coatings, like lubricants, are sacrificial for the benefit of the component. Bearing and sealing surfaces are routinely protected by tribologically paired coatings such as silicon diamond like coatings (SiDLC) in combination with an oil lubricated wave bearing that prolongs bearing operational life. Likewise, of several methods used or researched for detecting interface failures, dopants within coatings show failures in functionally graded ceramic coatings. The Bozzolo-Ferrante-Smith (BFS) materials models and quantum mechanical tools, employed in interface design, are discussed.

  8. Scaling Issues and Spatio-Temporal Variability in Ecohydrological Modeling on Mountain Topography: Methods and Future of the VELMA Model

    NASA Astrophysics Data System (ADS)

    Peterson, K.; Bond, B. J.; McKane, R.; Abdelnour, A. G.; Stieglitz, M.

    2010-12-01

    The interactions between vegetation and hydrology in mountainous terrain are difficult to represent in mathematical models. There are at least three primary reasons for this difficulty. First, expanding plot-scale measurements to the watershed scale requires finding the balance between computational intensity and physical significance. Second, parameters that affect soil, plant and hydrologic processes are distributed heterogeneously across mountain landscapes, and these patterns and processes may be spatially connected. Third, temporal variation in water availability (particularly in seasonal rainfall climates) may involve a “topographical memory” that may be expressed as “lags” between biological and hydrological processes. A unique opportunity for examining the implications of scaling and spatio-temporal variability on ecohydrological models exists at the H.J. Andrews Experimental Forest (HJA) in Blue River, Oregon. HJA is a National Science Foundation Long Term Ecological Research (LTER) site, and has been monitoring climate, stream, and vegetation characteristics of small watersheds for more than 50 years. A recent LIDAR (Light Detection and Ranging) reconnaissance has produced watershed scale estimations of vegetation and soil surface parameters at a very high spatial resolution, allowing spatially-explicit expansion of long-term data. An ecohydrological model, Visualizing Ecosystems for Land Management Assessments (VELMA) developed by the Stieglitz lab at Georgia Tech in collaboration with EPA has also been calibrated specifically for watershed topographies in HJA. VELMA is a coupled ecohydrological model that simulates the cycling and transport of water and nutrients in three dimensions by specific parameterization of hydrological and biogeochemical functions. It contains submodels for plant, soil, and water processes including surface and sub-surface flow on a daily time step. We are using the VELMA model to explore three sequential and fundamental

  12. Color management: printing processes - opportunities and limitations

    NASA Astrophysics Data System (ADS)

    Ingram, Samuel T.

    2002-06-01

    Digital tools have impacted traditional methods employed to reproduce color images during the past decade. The shift from a purely photomechanical process in color reproduction to colorimetric reproduction offers tremendous opportunity in the graphic arts industry. But good things do not necessarily come to all in the same package. Printing processes possess different reproduction attributes: tone reproduction, gray balance and color correction requirements are as different as the ingredient sets selected for color reproduction. This paper will provide insight toward understanding advantages and limitations offered by the new digital technologies in printing, publishing and packaging. For the past five years the Clemson University Graphic Communications Department has conducted numerous color projects using the new digital colorimetric tools during the previous decade. Several approaches have been used including experimental research and typical production workflows. The use of colorimetric data in color reproduction has given an opportunity to realize real gains in color use, predictability and consistency. Meeting an image's separation and reproduction requirements for a specified printing process can involve disruption of the anticipated workflow. Understanding the printing process requirements and the fit within the specifications of a colorimetric workflow are critical to the successful adoption of a color managed workflow. The paper will also provide an insight into the issues and challenges experienced with a color managed workflow. The printing processes used include offset litho, narrow and wide-web flexography (paper, liner board, corrugated and film), screen printing (paper board and polycarbonates), and digital imaging with toner, ink and inkjet systems. A proposal for technology integration will be the focus of the presentation drawn from documented experiences in over 300 applications of color management tools. Discussion will include the structure of

    Growing concern about biodiversity loss underscores the need to quantify and understand temporal change. Here, we review the opportunities presented by biodiversity time series, and address three related issues: (i) recognizing the characteristics of temporal data; (ii) selecting appropriate statistical procedures for analysing temporal data; and (iii) inferring and forecasting biodiversity change. With regard to the first issue, we draw attention to defining characteristics of biodiversity time series—lack of physical boundaries, uni-dimensionality, autocorrelation and directionality—that inform the choice of analytic methods. Second, we explore methods of quantifying change in biodiversity at different timescales, noting that autocorrelation can be viewed as a feature that sheds light on the underlying structure of temporal change. Finally, we address the transition from inferring to forecasting biodiversity change, highlighting potential pitfalls associated with phase-shifts and novel conditions. PMID:23097514

    Background While major clerkship blocks may have objectives related to specialized areas such as geriatrics, gay and lesbian bisexual transgender health, and palliative care, there is concern that teaching activities may not attend sufficiently to these objectives. Rather, these objectives are assumed to be met “by random opportunity”.(1) This study explored the case of geriatric learning opportunities on internal medicine clinical teaching units, to better understand the affordances and limitations of curriculum by random opportunity. Methods Using audio-recordings of morning case review discussions of 13 patients > 65 years old and the Canadian geriatric core competencies for medical students, we conducted a content analysis of each case for potential geriatric and non-geriatric learning opportunities. These learning opportunities were compared with attendings’ case review teaching discussions. The 13 cases contained 40 geriatric-related and 110 non-geriatric-related issues. While many of the geriatric issues (e.g., delirium, falls) were directly relevant to the presenting illness, attendings’ teaching discussions focused almost exclusively on non-geriatric medical issues, such as management of diabetes and anemia, many of which were less directly relevant to the reason for presenting to hospital. Results The authors found that the general medicine rotation provides opportunities to acquire geriatric competencies. However, the rare uptake of opportunities in this study suggests that, in curriculum-by-random-opportunity, presence of an opportunity does not justify the assumption that learning objectives will be met. Conclusions More studies are required to investigate whether these findings are transferrable to other vulnerable populations about which undergraduate students are expected to learn through curriculum by random opportunity.

  20. Compelling Research Opportunities using Isotopes

    SciTech Connect

    2009-04-23

    Isotopes are vital to the science and technology base of the US economy. Isotopes, both stable and radioactive, are essential tools in the growing science, technology, engineering, and health enterprises of the 21st century. The scientific discoveries and associated advances made as a result of the availability of isotopes today span widely from medicine to biology, physics, chemistry, and a broad range of applications in environmental and material sciences. Isotope issues have become crucial aspects of homeland security. Isotopes are utilized in new resource development, in energy from bio-fuels, petrochemical and nuclear fuels, in drug discovery, health care therapies and diagnostics, in nutrition, in agriculture, and in many other areas. The development and production of isotope products unavailable or difficult to get commercially have been most recently the responsibility of the Department of Energy's Nuclear Energy program. The President's FY09 Budget request proposed the transfer of the Isotope Production program to the Department of Energy's Office of Science in Nuclear Physics and to rename it the National Isotope Production and Application program (NIPA). The transfer has now taken place with the signing of the 2009 appropriations bill. In preparation for this, the Nuclear Science Advisory Committee (NSAC) was requested to establish a standing subcommittee, the NSAC Isotope Subcommittee (NSACI), to advise the DOE Office of Nuclear Physics. The request came in the form of two charges: one, on setting research priorities in the short term for the most compelling opportunities from the vast array of disciplines that develop and use isotopes and two, on making a long term strategic plan for the NIPA program. This is the final report to address charge 1. NSACI membership is comprised of experts from the diverse research communities, industry, production, and homeland security. NSACI discussed research opportunities divided into three areas: (1) medicine

    2013-01-01

    Nurses working or living near a community disaster have the opportunity to study health-related consequences to disaster or disaster recovery. In such a situation, the researchers need to deal with the conceptual and methodological issues unique to post-disaster research and know what resources are available to guide them, even if they have no specialized training or previous experience in disaster research. The purpose of this article is to review issues and challenges associated with conducting post-disaster research and encourage nurses to seek resources and seize opportunities to conduct research should the situation arise. Current disaster studies and the authors’ personal experiences conducting maternal-child research in post-Katrina New Orleans (2005–2013) provide real-life examples of how health professionals and nurses faced the challenges of doing post-disaster research. After catastrophic events, nurses need to step forward to conduct disaster research that informs and improves future disaster planning and health care responses. PMID:23899191

    [figure removed for brevity, see original site] Figure 1

    NASA's Mars Exploration Rover Opportunity landed on the red planet a year ago. This enhanced-resolution image from the Mars Orbiter Camera on NASA's Mars Global Surveyor orbiter is the only picture obtained thus far (by Jan. 24, 2005) that shows the tracks made by Opportunity.

    The image was acquired on April 26, 2004, during Opportunity's 91st martian day, or sol. That was the first day of Opportunity's extended mission, and the rover had recently completed exploration of small 'Fram Crater' on the route from its landing site toward 'Endurance Crater,' where it would eventually spend six months. The rover itself can be seen in this image -- an amazing accomplishment, considering that the orbiter was nearly 400 kilometers (nearly 250 miles) away at the time! Also visible and labeled on this image are the spacecraft's lander, backshell, parachute and heat shield, plus effects of its landing rockets.

    The camera captured this image with use of a technique called compensated pitch and roll targeted observation. In this method, the entire spacecraft rolls as it passes over the target area so the camera can scan in a way that sees details at three times higher resolution than the camera's normal high-resolution capability.

    The tracks made by Opportunity on the sandy surface of Meridiani Planum are not quite as visible from orbit as are the tracks made in Gusev Crater by the other Mars Exploration Rover, Spirit. A dustier surface at the Spirit site increases contrast between the tracks and the surrounding surfaces. Indeed, some parts of the track made by Opportunity are not visible in this image. Sunlight illuminates the scene from the left. North is toward the top of the image. The 100-meter scale bar is 109 yards long.

During the summer of 2004, I worked with Deborah Cotleur along with other staff members to create and modify customer satisfaction surveys. This office aims to assist in developing a model workplace by providing functions as a change agent to the center by serving as an advisor to management to ensure equity throughout the Center. In addition, the office serves as a mediator for the Center in addressing issues and concerns. Lastly, the office provides assistance to employees to enable attainment of personal and organizational goals. The Office of Equal Opportunities is a staff office which reports and provides advice to the Center Director and Executive Leadership, implements laws, regulations, and presidential executive orders, and provides center wide leadership and assistance to NASA GRC employees. Some of the major responsibilities of the office include working with the discrimination complaints program, special emphasis programs (advisory groups), management support, monitoring and evaluation, contract compliance, and community outreach. During my internship in this office, my main objective was to create four customer satisfaction surveys based on EO retreats, EO observances, EO advisory boards, and EO mediation/counseling. I created these surveys after conducting research on past events and surveys as well as similar survey research created and conducted by other NASA centers, program for EO Advisory group members, leadership training sessions for supervisors, preventing sexual harassment training sessions, and observance events. I also conducted research on the style and format from feedback surveys from the Marshall Equal Opportunity website, the Goddard website, and the main NASA website.

    The Fulbright Scholar Program is sponsored by the United States Department of State and is principally funded by taxpayer contributions. Bi-national in nature, it includes academic year opportunities for both American and foreign scholars. More than 800 grants in 125 countries are available each year. The Program supports research, teaching and lecturing opportunities in all academic disciplines, numerous professional fields and the arts. American academics and administrators have multiple opportunities to internationalize their campuses and their discipline points of view. Further, Fulbright not only sends American scholars abroad but also brings scholars to the United States and should be considered a strategic internationalization opportunity both for individuals and for campuses. During the 2013-14 competition cycle there were 33 awards available in physics and astronomy and 175 all discipline awards. The presentation will guide attendees in identifying appropriate opportunities through the Fulbright Scholar Program and will make suggestions as to how to be successful in a proposal. Special attention will be given to opportunities available for specialists in physics. The workshop will also cover non-Core Fulbright Scholar opportunities for physicists and university administrators, including a number of short-term, innovative programs that send an additional 400 scholars from the United States to universities and research institutes abroad to offer expertise on issues of global interest from cutting-edge research to policy, to technical expertise in curriculum development, institutional planning, program assessment, and institutional capacity building.

A number of them have created codes of conduct and competencies related to professionalism. Yet studies have shown that physicians face challenges as they seek to put the principles of professionalism into practice.

    Initiated in 1972, the Landsat program has provided a continuous record of earth observation for 35??years. The assemblage of Landsat spatial, spectral, and temporal resolutions, over a reasonably sized image extent, results in imagery that can be processed to represent land cover over large areas with an amount of spatial detail that is absolutely unique and indispensable for monitoring, management, and scientific activities. Recent technical problems with the two existing Landsat satellites, and delays in the development and launch of a successor, increase the likelihood that a gap in Landsat continuity may occur. In this communication, we identify the key features of the Landsat program that have resulted in the extensive use of Landsat data for large area land cover mapping and monitoring. We then augment this list of key features by examining the data needs of existing large area land cover monitoring programs. Subsequently, we use this list as a basis for reviewing the current constellation of earth observation satellites to identify potential alternative data sources for large area land cover applications. Notions of a virtual constellation of satellites to meet large area land cover mapping and monitoring needs are also presented. Finally, research priorities that would facilitate the integration of these alternative data sources into existing large area land cover monitoring programs are identified. Continuity of the Landsat program and the measurements provided are critical for scientific, environmental, economic, and social purposes. It is difficult to overstate the importance of Landsat; there are no other systems in orbit, or planned for launch in the short-term, that can duplicate or approach replication, of the measurements and information conferred by Landsat. While technical and political options are being pursued, there is no satellite image data stream poised to enter the National Satellite Land Remote Sensing Data Archive should system failures occur to Landsat-5 and -7.

  6. Carbon Storage in Biologic and Oceanic Reservoirs: Issues and Opportunities

    NASA Astrophysics Data System (ADS)

    Caldeira, K.

    2007-12-01

    Most discussion of carbon capture and storage have focused on geologic reservoirs because these are the reservoirs most likely to provide for long-term storage with a minimum of adverse environmental consequences. Nevertheless, there is interest in storage in other reservoirs such as the biosphere or the oceans. Storage in biological reservoirs such as forests or agricultural soils may in many cases be relatively inexpensive. Because this biological storage involves carbon dioxide removal from the atmosphere, it can potentially offset emissions from the transportation sector. Biological storage can be politically popular because it can be deployed with simple technologies, can be deployed in developing countries, and in many cases involves other environmental co-benefits. However, total capacity is limited. Furthermore, biological storage is temporary unless the store is actively maintained forever. Such temporary storage can be valuable, although it is clearly not as valuable as the quasi-permanent storage offered by good geologic storage reservoirs Ocean storage options fall into two main classes. The first involves conventional separation and compression of carbon dioxide from large point sources which would then be piped into the deep ocean and released either into the water or as a lake on the sea floor. In either case, the carbon dioxide would eventually interact with the atmosphere and contribute to ocean acidification. However, there is potential for the development of long-term engineered containment of carbon dioxide on or in the sea floor. The second main ocean storage option involves increasing ocean alkalinity, probably by dissolving carbonate minerals. This approach may offer safe, quasi- permanent, and cost-effective storage in settings where coastal carbon dioxide point sources are co-located with carbonate mineral deposits. Not every location or carbon dioxide source is suitable for geologic storage of carbon dioxide. At this early stage, it is important not to foreclose options that may, with further development, provide for long-term, safe, and cost- effective storage of carbon dioxide.

    1997-07-01

    The US electric utility industry is undergoing a period of fundamental change that has significant implications for Native American tribes. Although many details remain to be determined, the future electric power industry will be very different from that of the present. It is anticipated that the new competitive electric industry will be more efficient, which some believe will benefit all participants by lowering electricity costs. Recent developments in the industry, however, indicate that the restructuring process will likely benefit some parties at the expense of others. Given the historical experience and current situation of Native American tribes in the US, there is good reason to pay attention to electric industry changes to ensure that the situation of tribes is improved and not worsened as a result of electric restructuring. This paper provides a review of electricity restructuring in the US and identifies ways in which tribes may be affected and how tribes may seek to protect and serve their interests. Chapter 2 describes the current status of energy production and service on reservations. Chapter 3 provides an overview of the evolution of the electric industry to its present form and introduces the regulatory and structural changes presently taking place. Chapter 4 provides a more detailed discussion of changes in the US electric industry with a specific focus on the implications of these changes for tribes. Chapter 5 presents a summary of the conclusions reached in this paper.

    Explicitly modeling underlying relationships between a survival endpoint and processes that generate longitudinal measured or reported outcomes potentially could improve the efficiency of clinical trials and provide greater insight into the various dimensions of the clinical effect of interventions included in the trials. Various strategies have been proposed for using longitudinal findings to elucidate intervention effects on clinical outcomes such as survival. The application of specifically Bayesian approaches for constructing models that address longitudinal and survival outcomes explicitly has been recently addressed in the literature. We review currently available methods for carrying out joint analyses, including issues of implementation and interpretation, identify software tools that can be used to carry out the necessary calculations, and review applications of the methodology.

  6. No Shortcut for Opportunity

    NASA Technical Reports Server (NTRS)

    2004-01-01

    As NASA's Mars Exploration Rover Opportunity was making its way back toward its original entry path into 'Endurance Crater,' scientists and engineers spotted what they hoped might be a shortcut for climbing out of the crater. The possible exit path, pictured on the far right of this image where the outcrop is punctuated, was eventually deemed too hazardous for the rover to attempt. Opportunity would have had to cross terrain with a slope of 28 degrees and face a tall rock outcropping very close to the exit chute opening which, itself, is too narrow for the rover to pass. This stereo view combines several frames taken by the rover's navigation camera during Opportunity's 297th sol on Mars (Nov. 24, 2004). It is presented in a cylindrical-perspective projection with geometric seam correction. The location from which the image was taken has been designated as Opportunity's Site 38, Position 97.

    As of the Mars Exploration Rover Opportunity's 413th martian day, or sol, (March 23, 2005), the robot had driven a total of 4.62 kilometers (2.87 miles) since. The red line on this image traces the rover's route. The base image is a mosaic combining images from the Mars Observer Camera on NASA's Mars Global Surveyor orbiter, the Thermal Emission Imaging System on NASA's Mars Odyssey orbiter, and Opportunity's own Descent Image Motion Estimation System.

    The rover has been making rapid progress southward since it finished examining its jettisoned heat shield on sol 357 (Jan. 24, 2005, one year after landing). Scientists are eager for Opportunity to reach an area to the south called the 'Etched Terrain,' which appears mottled in the map's base images and might offer access to different layers of bedrock than what the rover has seen so far. See figure 1.

    As of the Mars Exploration Rover Opportunity's 414th martian day, or sol, (March 24, 2005), the robot had driven a total of 4.81 kilometers (2.99 miles) since landing. In this two-month period, Opportunity drove 2.69 kilometers (1.67 miles). As landmarks along the route, it used craters that the rover team informally named for ships of historic voyages of exploration. See figure 2. Figures 1 and 2 are traverse maps overlaid on a mosaic of images from NASA's Mars Global Surveyor and Mars Odyssey orbiters and from Opportunity's descent camera. The scale bar in figure 1 at lower left is 2 kilometers (1.24 miles) long and the scale bar in figure 2 is 1 kilometer (0.62 mile) long.

    Gilligan, Kimberly V

    2010-01-01

    Across the international field of safeguards there has been a rising awareness of the need for development of the next generation of safeguards professionals. The 2010 International Atomic Energy Agency Safeguards Symposium includes a suggested topic of 'developing safeguards professionals.' This can first be addressed by making university students and young professionals aware of safeguards and the unique career opportunities it encompasses. Then, once someone decides to go into safeguards he/she needs to be offered professional development opportunities in order to become a more effective member of the international safeguards community. This paper begins to do that by reviewing opportunities currently available. There are not many opportunities that are well advertised and this paper will serve to raise awareness of what does already exist and therefore benefit the international safeguards community. The current opportunities that will be discussed include training programs, graduate degrees, organizational outreach, professional networks, and intensive topic specific programs. The paper will also identify current needs and holes in the current offerings of professional development opportunities and suggest ways they can be filled. In the conclusion the paper addresses what types of programs are still needed.

    The Community Environmental Health Program/Community Outreach and Education Program (CEHP/COEP) New Mexico Center for Environmental Health Sciences has learned that listening and responding to opportunities that arise in local communities can be a more effective means of reaching health care providers, lay health workers, and community members than structured plans of action. While specific opportunities that have occurred in New Mexico may be unique, they are presented here with the hope that they might suggest new strategies to the reader and help to identify parallel opportunities in other communities. The paper is organized around three major opportunities to which CEHP/COEP has responded: (1) the need for more informed health care in communities with unique and complex environmental and occupational exposures due to their proximity to National Laboratories; (2) the need for resources on environmental health within local provider networks and issue-specific groups; and (3) the need for community environmental health projects within the College of Nursing. CEHP/COEP's responses, observations, and lessons learned through these experiences are discussed. In the end, the major lesson is that the ability to respond to opportunities requires flexibility and creativity; by sticking doggedly to plans, valuable-and sometimes more profitable and productive-opportunities may be missed.

    Product development teams are usually confronted with numerous issues in collaborative design process. The issue tracking management can provide the efficiency and effectiveness of the development process. Firstly, the process of issue tracking management and organization are analyzed. We study the relationship between privileges of role's and issue states. Secondly, we propose a product issues structure model (PISM) which associates issues with product at the component level. With the PISM, the developers can understand of the issue state so as to promote the issue resolution. Finally, we applied an approach which analyzes the density of product issues in the evolvement of product issue structure to assist the product manager in identifying improvement opportunities

    The advent of x-ray Free Electron Lasers will present a number of unique new scientific opportunities. These arise from their special characteristics which include intensely brilliant pulses of x-rays delivered in very short times, complete transverse coherence, and high photon quantum degeneracy, amongst other things. While clearly much thought needs to be given to a detailed quantitative assessment of the feasibility of various experiments using such sources, including methods of dealing with heat loads on beamline optics and radiation damage to samples, there are a number of areas in which one can see new opportunities, and other exciting possibilities about which one might speculate. In this talk the author briefly reviews some of these areas, such as x-ray holography, pump-probe type experiments, correlation spectroscopy and quantum optics experiments with x-rays.

    This report was commissioned by the California Institute for Energy Efficiency (CIEE) as part of its research mission to advance the energy efficiency and productivity of all end-use sectors in California. Our specific goal in this effort has been to identify viable research and development (R&D) opportunities that can improve capabilities to determine the energy-use and demand reductions achieved through demand-side management (DSM) programs and measures. We surveyed numerous practitioners in California and elsewhere to identify the major obstacles to effective impact evaluation, drawing on their collective experience. As a separate effort, we have also profiled the status of regulatory practices in leading states with respect to DSM impact evaluation. We have synthesized this information, adding our own perspective and experience to those of our survey-respondent colleagues, to characterize today`s state of the art in impact-evaluation practices. This scoping study takes a comprehensive look at the problems and issues involved in DSM impact estimates at the customer-facility or site level. The major portion of our study investigates three broad topic areas of interest to CIEE: Data analysis issues, field-monitoring issues, issues in evaluating DSM measures. Across these three topic areas, we have identified 22 potential R&D opportunities, to which we have assigned priority levels. These R&D opportunities are listed by topic area and priority.

    Over the past two decades, meson photo- and electro-production data of unprecedented quality and quantity have been measured at electromagnetic facilities worldwide. By contrast, the meson-beam data for the same hadronic final states are mostly outdated and largely of poor quality, or even nonexistent, and thus provide inadequate input to help interpret, analyze, and exploit the full potential of the new electromagnetic data. To reap the full benefit of the high-precision electromagnetic data, new high-statistics data from measurements with meson beams, with good angle and energy coverage for a wide range of reactions, are critically needed to advance our knowledge in baryon and meson spectroscopy and other related areas of hadron physics. To address this situation, a state of-the-art meson-beam facility needs to be constructed. Furthermore, the present paper summarizes unresolved issues in hadron physics and outlines the vast opportunities and advances that only become possible with such a facility.

    2014-12-01

    In the recent years, biosurfactants proved to be an interesting alternative to petrochemically derived surfactants. Two classes of biosurfactants, namely glycolipids and lipopeptides, have attracted significant commercial interest. Despite their environmental advantages and equal performance, commercialization of these molecules remains a challenge due to missing acquaintance of the applicants, higher price and lack of structural variation. The latter two issues can partially be tackled by screening for novel and better wild-type producers and optimizing the fermentation process. Yet, these traditional approaches cannot overcome all hurdles. In this review, an overview is given on how biotechnology offers opportunities for increased biosurfactant production and the creation of new types of molecules, in this way enhancing their commercial potential.

Additional information about the workshop, including relevant reading and presentations on multiphysics issues in applications, algorithms, and software, is available via https://sites.google.com/site/icismultiphysics2011/. We consider multiphysics applications from algorithmic and architectural perspectives, where 'algorithmic' includes both mathematical analysis and computational complexity and 'architectural' includes both software and hardware environments. Many diverse multiphysics applications can be reduced, en route to their computational simulation, to a common algebraic coupling paradigm. Mathematical analysis of multiphysics coupling in this form is not always practical for realistic applications, but model problems representative of applications discussed herein can provide insight. A variety of software frameworks for multiphysics applications have been constructed and refined within disciplinary communities and executed on leading-edge computer systems. We examine several of these, expose some commonalities among them, and attempt to extrapolate best practices to future systems. From our study, we summarize challenges and forecast opportunities. We also initiate a modest suite of test problems encompassing features present in many applications.

    Results from a survey of power utility biologists indicate that terrestrial biodiversity is considered a major issued by only a few utilities; however, a majority believe it may be a future issue. Over half of the respondents indicated that their company is involved in some management for biodiversity, and nearly all feel that it should be a goal for resource management. Only a few utilities are funding biodiversity research, but a majority felt more research was needed. Generally, larger utilities with extensive land holdings had greater opportunities and resources for biodiversity management. Biodiversity will most likely be a concern with transmission rights-of-way construction and maintenance, endangered species issues and general land resource management, including mining reclamation and hydro relicensing commitments. Over half of the companies surveyed have established voluntary partnerships with management groups, and biodiversity is a goal in nearly all the joint projects. Endangered species management and protection, prevention of forest fragmentation, wetland protection, and habitat creation and protection are the most common partnerships involving utility companies. Common management practices and unique approaches are presented, along with details of the survey. 4 refs.

    This three-dimensional model superimposes the Mars Exploration Rover Opportunity on one of its potential targets, a scientific treasure chest of martian rocks contained within the landing site, a crater on Meridiani Planum, Mars. The rover is placed on the rock outcrop for scale. Opportunity has not yet visited these rocks; it is currently still on its lander. Scientists plan to use the tools on the rover's instrument deployment device, or robotic 'arm,' to examine these rocks, which are about 10 centimeters (4 inches) high and approximately 8 meters (26 feet) away from the rover. The image of the terrain was acquired on Sol, or martian day, 2 of Opportunity's journey. This model was created using data from the rover's panoramic camera and is displayed using software developed by NASA's Ames Research Center.

    As NASA's Mars Exploration Rover Opportunity continues a southward trek from 'Erebus Crater' toward 'Victoria Crater,' the terrain consists of large sand ripples and patches of flat-lying rock outcrops, as shown in this image. Whenever possible, rover planners keep Opportunity on the 'pavement' for best mobility.

    This false-color image mosaic was assembled using images acquired by the panoramic camera on Opportunity's 784th sol (April 8, 2006) at about 11:45 a.m. local solar time. The camera used its 753-nanometer, 535-nanometer and 432-nanometer filters. This view shows a portion of the outcrop named 'Bosque,' including rover wheel tracks, fractured and finely-layered outcrop rocks and smaller, dark cobbles littered across the surface.

    SciTech Connect

    Dion, M.A.

    1995-09-01

    The escalating cost of environmental compliance, combined with fluctuating market conditions, have refiners struggling to remain profitable. To help maintain profitability, many refiners are realigning their processes and resources to allow them to run heavier, lower cost, opportunity crudes. Many of these heavier crudes are difficult to desalt (due to the lower density difference between the crude and water), and can significantly contribute to downstream corrosion, fouling and catalyst poisoning. Consequently, effective desalting is a critical first step to successfully processing these crudes. The real challenge when desalting these crudes is to maintain clean effluent brine and at the same time minimize total operating costs. Lose control of either, and the economic benefit of processing opportunity crudes in the first place can be diminished. This paper will discuss how recent technological advancements, specifically emulsion polymers combined with a patented split feed application technique, can help maintain optimum desalter performance and minimize overall treatment costs when processing opportunity crudes.

    2014-09-01

    In palliative care, where interactions cross clinical, pathological, psychological, social and spiritual considerations, it may be useful to take a minimal approach and avoid an overcomplicated or formulaic structure for the consultation. We will concern ourselves with points in the encounter where doctor and patient with or without family or carers need to be in agreement. Whether a consultation is based on a structured interview, a cue-based assessment or a narrative approach, the points of agreement or concordance need to cover four key areas; missing any of these has grave consequences for the clinical relationship. Without concordance, patients may be right to conclude that you don't know why you're all there (context), you don't know what's the matter (issues), you don't know what's going on (story) or you don't know what you're doing (plan). These four elements may serve also as a guide to the quality and effectiveness of an encounter among a doctor, patient and carers. We consider how this clinical method might integrate the nosological practices of doctors in palliative care services better, and we argue that finding concordance is likely to establish a better doctor-patient relationship at a human and professional level through empathy and trust rather than just a technical exchange.

    [figure removed for brevity, see original site] Click on the image for Opportunity's 'Olympia' Panorama (QTVR)

    This view from the panoramic camera on NASA's Mars Exploration Rover Opportunity shows an outcrop called 'Olympia' along the northwestern margin of 'Erebus' crater. The view spans about 120 degrees from side to side, generally looking southward. The outcrop exposes a broad expanse of sulfate-rich sedimentary rocks. The rocks were formed predominantly from windblown sediments, but some also formed in environmental conditions from damp to under shallow surface water. After taking the images that were combined into this view, Opportunity drove along along a path between sand dunes to the upper left side of the image, where a cliff in the background can be seen. This is a cliff is known as the 'Mogollon Rim.' Researchers expect it to expose more than 1 meter (3 feet) of new strata. These strata may represent the highest level observed yet by Opportunity. The image is an approximately true-color rendering generated using the panoramic camera's 750-nanometer, 530-nanometer and 430-nanometer filters.

    2009-01-01

    NASA's Mars Exploration Rover Opportunity used its navigation camera to take the images combined into this full-circle view of the rover's surroundings during the 1,825th Martian day, or sol, of Opportunity's surface mission (March 12, 2009). North is at the top.

    The rover had driven half a meter (1.5 feet) earlier on Sol 1825 to fine-tune its location for placing its robotic arm onto an exposed patch of outcrop including a target area informally called 'Cook Islands.' On the preceding sol, Opportunity turned around to drive frontwards and then drove 4.5 meters (15 feet) toward this outcrop. The tracks from the SOl 1824 drive are visible near the center of this view at about the 11 o'clock position. For scale, the distance between the parallel wheel tracks is about 1 meter (about 40 inches). Opportunity had previously been driving backward as a strategy to redistribute lubrication in a wheel drawing more electrical current than usual.

    The outcrop exposure that includes 'Cook Islands' is visible just below the center of the image.

    The terrain in this portion of Mars' Meridiani Planum region includes dark-toned sand ripples and lighter-toned bedrock.

    This view is presented as a cylindrical projection with geometric seam correction.

    2014-01-01

    The annual “LabEx MAbImprove industrial workshops” are primarily intended to provide scientists involved in therapeutic antibodies, a comprehensive view about topics of interest for the pharmaceutical industry. They are organized by the “LabEx MAbImprove industrial committee”, for this first edition especially in partnership with ARITT, the regional agency for innovation and technology transfer which operates in the French Région Centre, the 1st French region for pharmaceutical production. The 2013 edition, held May 28 at the Vinci Center of Tours, was dedicated to antibody biosimilars. Depending on opinions, the impending expiry of antibody patents and the imminent marketing approval of competitors to blockbusters can be perceived as good or bad things. Fears or opportunities? Risks for patients? Breath of fresh air for the health systems? Opportunity for re-industrializing France? In this context, it is necessary for people to form a fair and informed opinion on the current landscape of antibody biosimilars. In particular, this is especially important for scientists from the academic world, from the industry or from the regulation agencies, for pharmacists, for pharmacovigilance specialists, for health authorities, and staff from health insurance and decision makers. The first session was devoted to market and regulatory issues, and included both an overview of the evolution of the patent landscape and a description of biosimilars regulation in the European Union (EU). This session was closed by a talk on manufacturing processes for biosimilars. In the next session, quality control attributes of biosimilars were discussed and compared with the consistent quality of biotechnology products to raise the question: “How close is close enough?” In vitro assays for evaluating the Fc function of therapeutic antibodies were also discussed. The third session focused on development of biosimilars and primarily on the stepwise process for introducing an antibody

  13. Environmental issues in operations management

    NASA Astrophysics Data System (ADS)

    Muthulingam, Suresh

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

  15. Examining the ethical and social issues of health technology design through the public appraisal of prospective scenarios: a study protocol describing a multimedia-based deliberative method

    PubMed Central

    2014-01-01

    Background The design of health technologies relies on assumptions that affect how they will be implemented, such as intended use, complexity, impact on user autonomy, and appropriateness. Those who design and implement technologies make several ethical and social assumptions on behalf of users and society more broadly, but there are very few tools to examine prospectively whether such assumptions are warranted and how the public define and appraise the desirability of health innovations. This study protocol describes a three-year study that relies on a multimedia-based prospective method to support public deliberations that will enable a critical examination of the social and ethical issues of health technology design. Methods The first two steps of our mixed-method study were completed: relying on a literature review and the support of our multidisciplinary expert committee, we developed scenarios depicting social and technical changes that could unfold in three thematic areas within a 25-year timeframe; and for each thematic area, we created video clips to illustrate prospective technologies and short stories to describe their associated dilemmas. Using this multimedia material, we will: conduct four face-to-face deliberative workshops with members of the public (n = 40) who will later join additional participants (n = 25) through an asynchronous online forum; and analyze and integrate three data sources: observation, group deliberations, and a self-administered participant survey. Discussion This study protocol will be of interest to those who design and assess public involvement initiatives and to those who examine the implementation of health innovations. Our premise is that using user-friendly tools in a deliberative context that foster participants’ creativity and reflexivity in pondering potential technoscientific futures will enable our team to analyze a range of normative claims, including some that may prove problematic and others that may

    1996-01-01

    Magnetic levitation has been explored for application from motors to transportation. All of these applications have been at velocities where the physics of the air or operating fluids are fairly well known. Application of Maglev to hypersonic velocities (Mach greater than 5) presents many opportunities, but also issues that require understanding and resolution. Use of Maglev to upgrade the High Speed Test Track at Holloman Air Force Base in Alamogordo New Mexico is an actual hypersonic application that provides the opportunity to improve test capabilities. However, there are several design issues that require investigation. This paper presents an overview of the application of Maglev to the test track and the issues associated with developing a hypersonic Maglev sled. The focus of this paper is to address the issues with the Maglev sled design, rather than the issues with the development of superconducting magnets of the sled system.

    Purpose - This paper presents a method for handling everyday opportunities for improvement, led by floor staff in healthcare institutions. More than 400,000 incidents and accidents were recorded in Quebec healthcare institutions in 2013. The burden of treatment falls on hospital floor staff. The purpose of this paper is to raise the visibility of this problem and support staff better in their efforts to handle opportunities for improvement. Design/methodology/approach - Based on issues identified in the literature, which have been found to exist in various organizations, the method involved reviewing practices in the field, proposing a solution, and testing it to assess its relevance and limitations. The method was tested in partnership with the Centre Hospitalier de l'Université de Montréal, in the internal medicine unit at Hôtel-Dieu campus. The test lasted three months. Indicators from this test have been compared to results in the literature. Findings - The proposed method presents a 68 per cent increase in ideas generated per person and per week compared to the reference study. The mean time for closing actions was about 41 per cent better (lower) than in the reference case. Research limitations/implications - The test lasted 15 weeks; a longer test is needed to collect more data. Practical implications - The first practical implication of this study was the creation of a method allowing employees to seize opportunities for improvement in their daily work. The application of this method revealed: first, the operational nature of the proposal (empowerment of the work team); second, the operationalization of continuous improvement (71 per cent of ideas were finalized while the initiative was monitored); third, the smooth operation of the mechanism for facilitating continuous improvement (organization of weekly meetings and team participation in these meetings in 90 per cent of cases); and fourth, a shared feeling that intra- and inter-team communication had

    1996-08-01

    DOE orders mandate the development of a waste minimization program. The program`s goals are to: reduce volumes of wastes and toxicity; implement a system of tracking and reporting improvements; and devise a method for performing tasks. To satisfy the requirements of this program, Sandia conducts pollution prevention opportunity assessments (PPOAs) to identify waste-generating processes. The information collected from a PPOA then is used to identify waste minimization opportunities. This pollution prevention opportunity assessment was conducted using Sandia`s new methodology for prioritizing, evaluating and managing site-wide waste streams. This new methodology and the list of priority waste streams are described in the wastes revision of the Pollution Prevention Opportunity Assessment Plant. This PPOA addresses landscape waste minimization, partially in response to recent legislation and regulations.

  20. Opportunities for training in shrimp diseases.

    PubMed

    Lightner, D V; Redman, R M

    2007-01-01

    Opportunities for formal training in shrimp diseases were not available 30 years ago. This was because the shrimp farming industry was in its infancy with few significant disease issues and even fewer shrimp disease specialists investigating the causes of production losses. In 2006, more than two million metric tons of the marine penaeid shrimp were farmed, accounting for more than half of the world's supply. With most of the world's shrimp fisheries at maximum sustainable yields, the ratio of farmed to fished shrimp appears likely to continue to increase. The remarkable growth of sustainable shrimp farming was made possible through the development of methods to diagnose and manage disease in the world's shrimp farms. This occurred as the result of the development of training opportunities in shrimp disease diagnosis and control methods and the application of that knowledge, by an ever increasing number of shrimp diseases specialists, to disease management at shrimp farms. The first type of formal training to become generally available to the industry was in the form of special short courses and workshops. The first of these, which was open to international participants, was given at the University of Arizona in 1989. Since that first course several dozen more special short courses and workshops on shrimp diseases have been given by the University of Arizona. Dozens more special courses and workshops on shrimp diseases have been given by other groups, including other universities, industry cooperatives, governments and international aid agencies, in a wide range of countries (and languages) where shrimp farming constitutes an important industry. In parallel, graduate study programs leading to post graduate degrees, with shrimp disease as the research topic, have developed while formal courses in shrimp diseases have not become widely available in veterinary or fisheries college curricula in the USA and Europe, such courses are appearing in university programs

    [figure removed for brevity, see original site] Click on the image for 'Payson' Panorama by Opportunity (QTVR)

    The panoramic camera aboard NASA's Mars Exploration Rover Opportunity acquired this panorama of the 'Payson' outcrop on the western edge of 'Erebus' Crater during Opportunity's sol 744 (Feb. 26, 2006). From this vicinity at the northern end of the outcrop, layered rocks are observed in the crater wall, which is about 1 meters (3.3 feet) thick. The view also shows rocks disrupted by the crater-forming impact event and subjected to erosion over time.

    To the left of the outcrop, a flat, thin layer of spherule-rich soils overlies more outcrop materials. The rover is currently traveling down this 'road' and observing the approximately 25-meter (82-foot) length of the outcrop prior to departing Erebus crater.

    The panorama camera took 28 separate exposures of this scene, using four different filters. The resulting panorama covers about 90 degrees of terrain around the rover. This approximately true-color rendering was made using the camera's 753-nanometer, 535-nanometer and 423-nanometer filters. Image-to-image seams have been eliminated from the sky portion of the mosaic to better simulate the vista a person standing on Mars would see.

    Every year, all around the world, global environmental change affects the human habitat. This is effect enhanced by the mining operation, and creates new challenges in relationship between the mining and local community. The purpose of this project are developed the Stakeholders engagement evaluation plan which is currently developed in University of Nevada, Reno for the Emigrant mining project, located in the central Nevada, USA, and belong to the Newmont Mining Corporation, one of the gold production leader worldwide. The needs for this project is to create the open dialog between Newmont mining company and all interested parties which have social or environmental impacts from the Emigrant mine. Identification of the stakeholders list is first and one of the most difficult steps in the developing of mine social responsibility. Stakeholders' engagement evaluation plan must be based on the timing and available resources of the mining company, understanding the goals for the engagement, and on analyzes of the possible risks from engagement. In conclusion, the Stakeholders engagement evaluation plan includes: first, determinations of the stakeholders list, which must include any interested or effected by the mine projects groups, for example: state and local government representatives, people from local communities, business partners, environmental NGOs, indigenous people, and academic groups. The contacts and availability for communication is critical for Stakeholders engagement. Next, is to analyze characteristics of all these parties and determinate the level of interest and level of their influence on the project. The next step includes the Stakeholders matrix and mapping development, where all these information will be put together.After that, must be chosen the methods for stakeholders' engagement. The methods usually depends from the goals of engagement (create the dialog lines, collect the data, determinations of the local issues and concerns, or establish

  3. Ethical issues in stem cell research and therapy

    PubMed Central

    2014-01-01

    Rapid progress in biotechnology has introduced a host of pressing ethical and policy issues pertaining to stem cell research. In this review, we provide an overview of the most significant issues with which the stem cell research community should be familiar. We draw on a sample of the bioethics and scientific literatures to address issues that are specific to stem cell research and therapy, as well as issues that are important for stem cell research and therapy but also for translational research in related fields, and issues that apply to all clinical research and therapy. Although debate about the moral status of the embryo in human embryonic stem cell research continues to have relevance, the discovery of other highly multipotent stem cell types and alternative methods of isolating and creating highly multipotent stem cells has raised new questions and concerns. Induced pluripotent stem cells hold great promise, but care is needed to ensure their safety in translational clinical trials, despite the temptation to move quickly from bench to bedside. A variety of highly multipotent stem cells - such as mesenchymal stem/stromal cells and stem cells derived from amniotic fluid, umbilical cord blood, adipose tissue, or urine - present the opportunity for widespread biobanking and increased access. With these increased opportunities, however, come pressing policy issues of consent, control, and justice. The imperatives to minimize risks of harm, obtain informed consent, reduce the likelihood of the therapeutic misconception, and facilitate sound translation from bench to bedside are not unique to stem cell research; their application to stem cell research and therapy nonetheless merits particular attention. Because stem cell research is both scientifically promising and ethically challenging, both the application of existing ethical frameworks and careful consideration of new ethical implications are necessary as this broad and diverse field moves forward.

    The discovery of haploids in higher plants led to the use of doubled haploid (DH) technology in plant breeding. This article provides the state of the art on DH technology including the induction and identification of haploids, what factors influence haploid induction, molecular basis of microspore embryogenesis, the genetics underpinnings of haploid induction and its use in plant breeding, particularly to fix traits and unlock genetic variation. Both in vitro and in vivo methods have been used to induce haploids that are thereafter chromosome doubled to produce DH. Various heritable factors contribute to the successful induction of haploids, whose genetics is that of a quantitative trait. Genomic regions associated with in vitro and in vivo DH production were noted in various crops with the aid of DNA markers. It seems that F2 plants are the most suitable for the induction of DH lines than F1 plants. Identifying putative haploids is a key issue in haploid breeding. DH technology in Brassicas and cereals, such as barley, maize, rice, rye and wheat, has been improved and used routinely in cultivar development, while in other food staples such as pulses and root crops the technology has not reached to the stage leading to its application in plant breeding. The centromere-mediated haploid induction system has been used in Arabidopsis, but not yet in crops. Most food staples are derived from genomic resources-rich crops, including those with sequenced reference genomes. The integration of genomic resources with DH technology provides new opportunities for the improving selection methods, maximizing selection gains and accelerate cultivar development. Marker-aided breeding and DH technology have been used to improve host plant resistance in barley, rice, and wheat. Multinational seed companies are using DH technology in large-scale production of inbred lines for further development of hybrid cultivars, particularly in maize. The public sector provides support to

  6. Ethical issues in livestock cloning.

    PubMed

    Thompson, P B

    1999-01-01

    Although cloning may eventually become an important technology for livestock production, four ethical issues must be addressed before the practice becomes widespread. First, researchers must establish that the procedure is not detrimental to the health or well-being of affected animals. Second, animal research institutions should evaluate the net social benefits to livestock producers by weighing the benefits to producers against the opportunity cost of research capacity lost to biomedical projects. Third, scientists should consider the indirect effects of cloning research on the larger ethical issues surrounding human cloning. Finally, the market structure for products of cloned animals should protect individual choice, and should recognize that many individuals find the prospect of cloning (or consuming cloned animals) repugnant. Analysis of these four issues is complicated by spurious arguments alleging that cloning will have a negative impact on environment and genetic diversity. PMID:15719505

    can (and ultimately must) learn to capture and re-use P in human and animal wastes. And, as Carpenter and Bennett highlight, inequities in P availability across world regions are not just a problem, they are an opportunity: transfers from P-rich to P-poor regions could simultaneously reduce environmental and food security risks. Above all, Carpenter and Bennett's analyses highlight the need for new management strategies that better target not only P's environmental risks, but also recognize the element's standing as an irreplaceable resource. Human society has been built from the massive alteration of four global biogeochemical cycles (C, N, H2O and P). We can replace carbon-based fuels, plant legumes in lieu of Haber-Bosch-based N fixation, and the rain will still fall. But for P, there is neither substitute nor renewal. Without an almost closed loop between fertilizer application, food consumption, and waste management, society could solve the remainder of the environmental threats Rockström and colleagues identify, and still be facing a bleak future.

    Advanced Instrumentation in the Educational Laboratory The instruments that chemists use in their research have changed dramatically in the past decades. The explosion in new techniques and their instrumental counterparts has been made possible by two significant advances. The rapid propagation of computer chips and circuitry provides opportunities to collect more specialized and refined data than ever before. Computer-controlled instruments can detect events that a human researcher would never perceive and can record hundreds of data points in the time that a person could only observe one or two. Coupled with these advances in technology are advances in theory that allow more sophisticated interpretation of data. A hundred years ago a sophisticated instrument was a balance that could weigh minute quantities. Today a sophisticated instrument is one that can identify the composition of that minute sample, determine its molecular weight, or reveal a great deal about its energy states and bonding. This bonanza of new instruments is wonderful for the research chemist but a curricular headache for the chemistry teacher. It takes more time to learn how to run an NMR than to use a balance, and more sophistication on the part of the student is needed to interpret the data. And yet many courses that only a generation ago sported an expensive analytical balance as its prize instrument now require students to understand and operate a whole panoply of complex tools. Teachers faced with accommodating these curricular changes will find several articles in this issue helpful--either providing information on new techniques or descriptions of how to incorporate them into the classroom. Electrospray ionization mass spectrometry is one of the newest tools that has been added to the analytical arsenal. It is an extension of mass spectrometry that overcomes the old barrier that allowed only analysis of low molecular weight, volatile compounds. It is now possible to use MS for

    2015-11-15

    Health Impact Assessment (HIA) is recognized as a useful tool that can identify potential health impacts resulting from projects or policy initiatives. Although HIA has become an established practice in some countries, it is not yet an established practice in Canada. In order to enable broader support for HIA, this study provides a comprehensive review and analysis of the peer-reviewed and gray literature on the state of HIA practice. The results of this review revealed that, although there is an abundance of publications relating to HIA, there remains a lack of transparent, consistent and reproducible approaches and methods throughout the process. Findings indicate a need for further research and development on a number of fronts, including: 1) the nature of HIA triggers; 2) consistent scoping and stakeholder engagement approaches; 3) use of evidence and transparency of decision-making; 4) reproducibility of assessment methods; 5) monitoring and evaluation protocols; and, 6) integration within existing regulatory frameworks. Addressing these issues will aid in advancing the more widespread use of HIA in Canada. - Highlights: • Reviewed current state of practice in the field of HIA • Identified key obstacles and opportunities for HIA advancement • Major issues include lack of consistent approach and methodology. • No national regulatory driver hinders opportunity for widespread use of HIA. • Identified research opportunities vital to developing HIA practice in Canada.

    Nanotechnology seeks to exploit novel physical, chemical, biological, mechanical, electrical, and other properties, which arise primarily due to the nanoscale nature of certain materials. A key example is carbon nanotubes (CNTs) which exhibit unique electrical and extraordinary mechanical properties and offer remarkable potential for revolutionary applications in electronics devices, computing, and data storage technology, sensors, composites, nanoelectromechanical systems (NEMS), and as tip in scanning probe microscopy (SPM) for imaging and nanolithography. Thus the CNT synthesis, characterization, and applications touch upon all disciplines of science and engineering. This presentation will provide an overview and progress report on this and other major research candidates in Nanotechnology and address opportunities and challenges ahead.

The, at this point largely unexamined, plethora of possibilities going forward, a subset of which is discussed, could literally reinvent aerospace but requires triage of many possibilities. Such initial upfront homework would lengthen the Research and Development (R&D) time frame but could greatly enhance the affordability and performance of the evolved products and capabilities. Structural nanotubes and exotic energetics along with some unique systems approaches are particularly compelling.

    Scrutinized from the perspective of time, the giants in the history of crystallography more than once missed a nearly obvious chance to make another great discovery, or went in the wrong direction. This review analyzes such missed opportunities focusing on macromolecular crystallographers (using Perutz, Pauling, Franklin as examples), although cases of particular historical (Kepler), methodological (Laue, Patterson) or structural (Pauling, Ramachandran) relevance are also described. Linus Pauling, in particular, is presented several times in different circumstances, as a man of vision, oversight, or even blindness. His example underscores the simple truth that also in science incessant creativity is inevitably connected with some probability of fault. PMID:24814223

  16. Using strategic foresight to assess conservation opportunity.

    PubMed

    Cook, Carly N; Wintle, Bonnie C; Aldrich, Stephen C; Wintle, Brendan A

    2014-12-01

    The nature of conservation challenges can foster a reactive, rather than proactive approach to decision making. Failure to anticipate problems before they escalate results in the need for more costly and time-consuming solutions. Proactive conservation requires forward-looking approaches to decision making that consider possible futures without being overly constrained by the past. Strategic foresight provides a structured process for considering the most desirable future and for mapping the most efficient and effective approaches to promoting that future with tools that facilitate creative thinking. The process involves 6 steps: setting the scope, collecting inputs, analyzing signals, interpreting the information, determining how to act, and implementing the outcomes. Strategic foresight is ideal for seeking, recognizing, and realizing conservation opportunities because it explicitly encourages a broad-minded, forward-looking perspective on an issue. Despite its potential value, the foresight process is rarely used to address conservation issues, and previous attempts have generally failed to influence policy. We present the strategic foresight process as it can be used for proactive conservation planning, describing some of the key tools in the foresight tool kit and how they can be used to identify and exploit different types of conservation opportunities. Scanning is an important tool for collecting and organizing diverse streams of information and can be used to recognize new opportunities and those that could be created. Scenario planning explores how current trends, drivers of change, and key uncertainties might influence the future and can be used to identify barriers to opportunities. Backcasting is used to map out a path to a goal and can determine how to remove barriers to opportunities. We highlight how the foresight process was used to identify conservation opportunities during the development of a strategic plan to address climate change in New York

    2016-04-01

    Multibeam echosounder data comprise the primary source for digital terrain models of the seafloor. Recent advances in seafloor surveying technologies have resulted in a dramatic increase in the quantity and resolution of multibeam echosounder data, prompting a renewed interest in employing geomorphometric techniques to investigate the seafloor. Marine geomorphometric techniques are not as varied and as extensively applied as in terrestrial environments. This is due to the difficultly with capturing terrain variability underwater, since changes in topography are more subdued in comparison to terrestrial landscapes. Issues related to scale are also relevant in submarine settings, but they manifest themselves differently due to the differences in input data. In the last decade, a suite of marine geomorphometric techniques have been developed - terrain attributes, feature-based quantitative representation, automated classification - and employed to investigate a wide range of phenomena - seafloor landforms and geomorphic processes, geohazards, hydrodynamics, habitats. This contribution provides an overview of progress made in marine geomorphometry in the last decade as well as highlights the opportunities and challenges faced by this thriving field of research in the near future.

    Over the past two decades, meson photo- and electro-production data of unprecedented quality and quantity have been measured at electromagnetic facilities worldwide. By contrast, the meson-beam data for the same hadronic final states are mostly outdated and largely of poor quality, or even nonexistent, and thus provide inadequate input to help interpret, analyze, and exploit the full potential of the new electromagnetic data. To reap the full benefit of the high-precision electromagnetic data, new high-statistics data from measurements with meson beams, with good angle and energy coverage for a wide range of reactions, are critically needed to advance our knowledgemore » in baryon and meson spectroscopy and other related areas of hadron physics. To address this situation, a state of-the-art meson-beam facility needs to be constructed. Furthermore, the present paper summarizes unresolved issues in hadron physics and outlines the vast opportunities and advances that only become possible with such a facility.« less

    Martin, Ambroise

    2010-01-01

    During the past decade, the use of claims became more and more important in many countries in relation to the increased awareness of consumer about the link between foods and health, offering to industry a valuable opportunity to differentiate and valorize their products and to promote innovation. However, more and more stringent regulations are developed, all based on the general principles adopted by the Codex Alimentarius Commission. In addition to the different regulatory processes and administrative requirements according to the country, the high level (and cost) of scientific substantiation of claims, the constraints introduced by nutrient profiles and the poor knowledge of the impact on consumer depending on the cultural contexts may limit these opportunities or, at least complicate their use. All these issues are briefly analyzed, highlighting some striking convergences and differences between countries. PMID:20664223

    Increasing quantities of wastes and more stringent disposal regulations combined with the public`s desire to see integrated waste management strategies have created an atmosphere of opportunity. A number of processes are being developed by the Energy and Environmental Research Center (EERC) that offer solutions to the burgeoning waste problem. In the area of solid waste processing, municipal solid wastes have been carbonized and converted into a benign, high quality slurry fuel. Pelletizing and briquetting activities have produced high-quality solid fuels. Extensive efforts have been undertaken in market development for recycled materials, specializing in tertiary recycling of plastics. The issues facing systems for the conversion of opportunity fuels to energy have been addressed for both the combustion and gasification mode, using such diverse fuels as sewage sludge, wood chips, automotive shredder residue, and sunflower hulls. Conversion of biomass to direct-use fuels has also been an ongoing concern and a major focus of the EERC. The focus of this paper will be the identification of methods for converting wastes into valuable fuels or other ``products`` and how they can be used to enhance power generation options.

  6. Ionospheric research opportunity

    NASA Astrophysics Data System (ADS)

    1985-05-01

    Ground-based explosions have been exploited successfully in the past as a relatively controlled source for producing ionospheric disturbances. On June 25, the Defense Nuclear Agency will conduct a high explosives test on the northern section of the White Sands Missile Range. Approximately 4,800 tons of ammonium nitrate and fuel oil (ANFO) will be detonated at ground level, producing an acoustic shock wave with a surface pressure change of approximately 20 mbar at a 6 km range. This shock front will have sufficient strength to propagate into the ionosphere with at least a 10% change in the ambient pressure across the disturbance front in the lower F region. Such an ionospheric perturbation will give ionospheric researchers an excellent opportunity to investigate acoustic propagation at ionospheric heights, shock dissipation effect, the ion-neutral coupling process, acoustic-gravity wave (traveling ionospheric disturbance) generation mechanisms, and associated RF phenomena.

    The LSST design is driven by four science themes: dark energy and matter, Galactic structure, transient objects, and the Solar System inventory. These and many other science opportunities are described in the LSST Science Book: http://www.lsst.org/lsst/scibook The LSST will carry out a ten-year very deep imaging survey of 18,000 sq.deg. of the sky in six broad optical bands, with a deep stack reaching r 27.5 (5 sigma, point source). The LSST design, with an 8.4m (6.7m effective) primary mirror and a 9.6 square degree field of view, will allow about 10,000 square degrees of sky to be imaged to an effective depth of r=24.5 every three nights. Each patch of the sky will be visited over 800 times with pairs of 15 sec exposures, opening a new window on the universe: faint time-domain. The resulting petabytes of data will be made available to the US and Chilean communities for scientific investigations ranging from the properties of near-Earth asteroids, to characterizations of dark energy from strong and weak lensing, galaxy clustering, and distant supernovae. More information is available at http://www.lsst.org Eleven LSST Science Collaborations are actively laying the groundwork for first light: working on image analysis algorithms and database design, exploring cadence choices, developing commissioning plans, and outlining scientific opportunities. These Collaborations have over 200 members to date, with membership open to the US and Chilean communities via an application process administered by NOAO. Full end-to-end LSST image simulations are a useful resource for exploring science capability.

  9. Evolutionary constraints or opportunities?

    PubMed Central

    Sharov, Alexei A.

    2014-01-01

    Natural selection is traditionally viewed as a leading factor of evolution, whereas variation is assumed to be random and non-directional. Any order in variation is attributed to epigenetic or developmental constraints that can hinder the action of natural selection. In contrast I consider the positive role of epigenetic mechanisms in evolution because they provide organisms with opportunities for rapid adaptive change. Because the term “constraint” has negative connotations, I use the term “regulated variation” to emphasize the adaptive nature of phenotypic variation, which helps populations and species to survive and evolve in changing environments. The capacity to produce regulated variation is a phenotypic property, which is not described in the genome. Instead, the genome acts as a switchboard, where mostly random mutations switch “on” or “off” preexisting functional capacities of organism components. Thus, there are two channels of heredity: informational (genomic) and structure-functional (phenotypic). Functional capacities of organisms most likely emerged in a chain of modifications and combinations of more simple ancestral functions. The role of DNA has been to keep records of these changes (without describing the result) so that they can be reproduced in the following generations. Evolutionary opportunities include adjustments of individual functions, multitasking, connection between various components of an organism, and interaction between organisms. The adaptive nature of regulated variation can be explained by the differential success of lineages in macro-evolution. Lineages with more advantageous patterns of regulated variation are likely to produce more species and secure more resources (i.e., long-term lineage selection). PMID:24769155

    Exercise psychology encompasses the disciplines of psychiatry, clinical and counseling psychology, health promotion, and the movement sciences. This emerging field involves diverse mental health issues, theories, and general information related to physical activity and exercise. Numerous research investigations across the past 20 years have shown both physical and psychological benefits from physical activity and exercise. Exercise psychology offers many opportunities for growth while positively influencing the mental and physical health of individuals, communities, and society. However, the exercise psychology literature has not addressed ethical issues or dilemmas faced by mental health professionals providing exercise psychology services. This initial discussion of ethical issues in exercise psychology is an important step in continuing to move the field forward. Specifically, this article will address the emergence of exercise psychology and current health behaviors and offer an overview of ethics and ethical issues, education/training and professional competency, cultural and ethnic diversity, multiple-role relationships and conflicts of interest, dependency issues, confidentiality and recording keeping, and advertisement and self-promotion.

    Mathis, M.L.

    1999-12-31

    This article examines a unique application of integrated assessment methodologies to analyze water scarcity, development and the environment in the semi-arid Lower Rio Grande/Rio Bravo watershed. US and Mexican data are analyzed to produce an integrated baseline report of current socio-economic, ecological, water supply and demand, water quality, and management conditions and trends. The baseline report provides the basis for subsequent analysis of alternative future scenarios for the region. Scenarios are developed by combining demographic projections with alternatives for future water availability, irrigation technologies, and management practices. The integrated assessment methodology is evaluated as a general tool for environmental decision-making. Problems encountered in applying the methodology are discussed, as are possibilities for improvements. The article concludes that, despite inherent difficulties, integrated assessments can provide a powerful framework by which to analyze complex environmental issues involving different disciplines and large amounts of information.

    Vietnam`s energy needs are clear and acute. Economic reforms have triggered a dynamic development process with a large and growing appetite for power. In view of the Vietnamese government`s own shortages of capital, private international power companies have been identified as key problem-solvers in the country`s efforts to meet a skyrocketing demand for energy resources. There are no restrictions on the nature of projects in which non-Vietnamese investors may participate. A number of legal issues need resolution before independent power producers can take advantage of the Republic`s recently created Builder-Operator-Transfer Contracts (the BOT Regulations). This paper discusses these regulations and how they affect independent power producers

    The objective in this paper is about economic dispatch problem of electric power generation where scheduling the committed generating units outputs so as to meet the required load demand at minimum operating cost, while satisfying all units and system equality and inequality constraint. In the operating of electric power system, an economic planning problem is one of variables that its must be considered since economically planning will give more efficiency in operational cost. In this paper the economic dispatch problem which has non linear cost function solved by using swarm intelligent method is Gaussian Particle Swarm Optimization (GPSO) and Lagrange Multiplier. GPSO is a population-based stochastic algorithms which their moving inspired by swarm intelligent and probabilities theories. To analize its accuracy, the economic dispatch solution by GPSO method will be compared with Lagrange multiplier method. From the running test result the GPSO method give economically planning calculation which it better than Lagrange multiplier method and the GPSO method faster to getting error convergence. Therefore the GPSO method have better performance to getting global best solution than the Lagrange method.

  8. Geomagnetically Induced Currents: Progress and Issues

    NASA Astrophysics Data System (ADS)

    2010-05-01

    Geomagnetically induced currents (GIC) are a hazard to conducting networks such as high-voltage power and pipeline grids. GIC have been known for decades to affect power systems at higher latitudes (e.g. Europe and North America), although more recently GIC have also been found to affect power networks at middle and lower latitudes. Mitigating the effects of GIC remains an issue for the power and pipeline industries and for governments concerned with the societal and economic implications. To understand, e.g. to model and predict, GIC in conducting grids needs expertise drawn from electrical engineering, geophysics and space weather science - a truly multi-disciplinary undertaking. In terms of geophysics and space physics, issues such as Earth structure (e.g. 3D versus 1D mantle and lithospheric conductivity structure), ocean/continent conductivity contrasts, ionospheric current systems and their variability and Sun-Earth magnetic interactions are all relevant. The start of solar cycle 24 provides an opportune time to consider the status of GIC research and to assess what new studies are required in geophysical modelling and in hazard analysis. What do we need to improve on to better specify/predict GIC flowing in power grids, from ‘up-stream' observations of coronal mass ejections through to geomagnetic field measurements made during magnetic storms? In this invited review we will consider aspects of a) Measurement: how do we measure GIC in grids; b) Analysis: how do measured GIC relate to geophysical and space physics data; c) Modelling: what methods exist for modelling GIC, again in relation to other data, and how accurate are models; and d) Prediction: how predictable are GIC and what are the implications for, e.g., the power industry and national governments. We will review the more recent developments in GIC and related geomagnetism and space weather science. We will outline what issues are widely believed to now be understood and what issues remain to be

  9. Indirect cost in economic evaluation: the opportunity cost of unpaid inputs.

    PubMed

    Posnett, J; Jan, S

    1996-01-01

    Unpaid time represents a potentially significant input into the health production function. The paper sets out the basis for valuation of time inputs consistent with the notion of opportunity cost. Such analysis requires consideration of whether time displaced in the production of health involves lost work or lost leisure. Furthermore, because valuation of opportunity cost requires the consistent treatment of costs and benefits, the study also considers the valuation of outputs. The basis for valuing the shadow price of work time is examined by firstly assuming perfect competition. The analysis then considers the presence of monopoly and monopsony in product markets and income and sales taxes. The basis for valuing the shadow price of leisure ("leisure' being all uses of time except paid employment) is restricted to an examination of methods previously used to value unpaid housework. The two methods examined are the replacement cost and the opportunity cost method. As the methods are not equivalent, the circumstances where each is appropriate vary depending on whether the output lost in producing health is replaced. Although not set out as the primary focus of the paper, the issues surrounding the valuation of outputs generated by non-market and quasi-market activity are examined. In particular, where activities such as informal care result in indirect utility to the carers (and patients) themselves, it is likely the full market wage provides a lower bound estimate of the value of marginal benefit. Finally the paper provides a practical approach to examining opportunity cost of unpaid inputs consistent with the concepts set out in preceding sections. PMID:8653189

    The outcome of drug therapy is often unpredictable, ranging from beneficial effects to lack of efficacy to serious adverse effects. Variations in single genes are 1 well-recognized cause of such unpredictability, defining the field of pharmacogenetics (see Glossary). Such variations may involve genes controlling drug metabolism, drug transport, disease susceptibility, or drug targets. The sequencing of the human genome and the cataloguing of variants across human genomes are the enabling resources for the nascent field of pharmacogenomics (see Glossary), which tests the idea that genomic variability underlies variability in drug responses. However, there are many challenges that must be overcome to apply rapidly accumulating genomic information to understand variable drug responses, including defining candidate genes and pathways; relating disease genes to drug response genes; precisely defining drug response phenotypes; and addressing analytic, ethical, and technological issues involved in generation and management of large drug response data sets. Overcoming these challenges holds the promise of improving new drug development and ultimately individualizing the selection of appropriate drugs and dosages for individual patients. PMID:17116919

    A correlation method to predict pressures induced on an infinite plate by a jet exhausting normal to the plate into a subsonic free stream was extended to jets exhausting at angles to the plate and to jets exhausting normal to the surface of a body revolution. The complete method consisted of an analytical method which models the blockage and entrainment properties of the jet and an empirical correlation which accounts for viscous effects. For the flat plate case, the method was applicable to jet velocity ratios up to ten, jet inclination angles up to 45 deg from the normal, and radial distances up to five diameters from the jet. For the body of revolution case, the method was applicable to a body at zero degrees angle of attack, jet velocity ratios 1.96 and 3.43, circumferential angles around the body up to 25 deg from the jet, axial distances up to seven diameters from the jet, and jet-to-body diameter ratios less than 0.1.

    Tuberculosis (TB) has been a disease affecting almost all parts of the world since ages. Lot many efforts came in the past for improving diagnosis and treatment. Also, an effective vaccine has been sought after for long. With the emergence of resistant strains of Mycobacterium tuberculosis, the causal organisms of tuberculosis, and complexities emerging due to other associated infections and disease conditions, there is a desperate need for further research input in the field. Be it the better medication and care or better resistance management, proper diagnostics holds the key to success. It has been observed that a high burden of the disease was accompanied by resource limitations and poor research set-up. The scenario remained like this for several decades. With the refreshed vision of resourceful countries and funding agencies, funding is being provided in many areas of research in tuberculosis diagnosis and treatment. This review has been written with an aim to bring forth the limitations of available methods in the field of diagnostics and making researchers aware about the changing scenario with better funding opportunities and support. The author visualizes an enthusiasm from all over the world for the development of better modalities and urges scientists to join the struggle at this very perfect time to take the challenge and come forward with innovations in this field.

    2015-01-01

    Immunotherapy has great potential to treat cancer and prevent future relapse by activating the immune system to recognize and kill cancer cells. A variety of strategies are continuing to evolve in the laboratory and in the clinic, including therapeutic noncellular (vector-based or subunit) cancer vaccines, dendritic cell vaccines, engineered T cells, and immune checkpoint blockade. Despite their promise, much more research is needed to understand how and why certain cancers fail to respond to immunotherapy and to predict which therapeutic strategies, or combinations thereof, are most appropriate for each patient. Underlying these challenges are technological needs, including methods to rapidly and thoroughly characterize the immune microenvironment of tumors, predictive tools to screen potential therapies in patient-specific ways, and sensitive, information-rich assays that allow patient monitoring of immune responses, tumor regression, and tumor dissemination during and after therapy. The newly emerging field of immunoengineering is addressing some of these challenges, and there is ample opportunity for engineers to contribute their approaches and tools to further facilitate the clinical translation of immunotherapy. Here we highlight recent technological advances in the diagnosis, therapy, and monitoring of cancer in the context of immunotherapy, as well as ongoing challenges. PMID:26598681

    1998-05-01

    This paper discusses thermal analysis in support of probabilistic risk assessment (PRA) to predict the heating of cargoes shipped in vehicles like the Safe Secure Trailer. Fire environments contribute very significantly to the risk associated with ground transport of special nuclear materials. The tradeoff between thermal model complexity and the affordable number of scenarios used to represent the hazard space is discussed as it impacts PRA. The relevant heat transfer mechanisms are discussed along with the applicability of methods from the literature for analysis of these mechanisms. Many of the subject`s real problems remain too complex for affordable and rigorous analysis. Available models are generally restricted to idealizations that are quickly obviated by real effects. Approximate treatment methods, striving to produce conservative, realistic estimates are also discussed.

  1. Some issues related to the novel spectral acceleration method for the fast computation of radiation/scattering from one-dimensional extremely large scale quasi-planar structures

    NASA Astrophysics Data System (ADS)

    Torrungrueng, Danai; Johnson, Joel T.; Chou, Hsi-Tseng

    2002-03-01

    The novel spectral acceleration (NSA) algorithm has been shown to produce an $[\\mathcal{O}]$(Ntot) efficient iterative method of moments for the computation of radiation/scattering from both one-dimensional (1-D) and two-dimensional large-scale quasi-planar structures, where Ntot is the total number of unknowns to be solved. This method accelerates the matrix-vector multiplication in an iterative method of moments solution and divides contributions between points into ``strong'' (exact matrix elements) and ``weak'' (NSA algorithm) regions. The NSA method is based on a spectral representation of the electromagnetic Green's function and appropriate contour deformation, resulting in a fast multipole-like formulation in which contributions from large numbers of points to a single point are evaluated simultaneously. In the standard NSA algorithm the NSA parameters are derived on the basis of the assumption that the outermost possible saddle point, φs,max, along the real axis in the complex angular domain is small. For given height variations of quasi-planar structures, this assumption can be satisfied by adjusting the size of the strong region Ls. However, for quasi-planar structures with large height variations, the adjusted size of the strong region is typically large, resulting in significant increases in computational time for the computation of the strong-region contribution and degrading overall efficiency of the NSA algorithm. In addition, for the case of extremely large scale structures, studies based on the physical optics approximation and a flat surface assumption show that the given NSA parameters in the standard NSA algorithm may yield inaccurate results. In this paper, analytical formulas associated with the NSA parameters for an arbitrary value of φs,max are presented, resulting in more flexibility in selecting Ls to compromise between the computation of the contributions of the strong and weak regions. In addition, a ``multilevel'' algorithm

During clinical practice the researcher observed that integrated services may not be rendered. Objectives This article describes the experiences of mothers that utilised comprehensive child health services in the Cape Metropolitan area of South Africa. Services included treatment for diseases; preventative interventions such as immunisation; and promotive interventions, such as improvement in nutrition and promotion of breastfeeding. Method A qualitative, descriptive phenomenological approach was applied to explore the experiences and perceptions of mothers and/or carers utilising child healthcare services. Thirty percent of the clinics were selected purposively from the total population. A convenience purposive non-probability sampling method was applied to select 17 mothers who met the criteria and gave written consent. Interviews were conducted and recorded digitally using an interview guide. The data analysis was done using Tesch's eight step model. Results Findings of the study indicated varied experiences. Not all mothers received information about the Road to Health book or card. According to the mothers, integrated child healthcare services were not practised. The consequences were missed opportunities in immunisation, provision of vitamin A, absence of growth monitoring, feeding assessment and provision of nutritional advice. Conclusion There is a need for simple interventions such as oral rehydration, early recognition and treatment of diseases, immunisation, growth monitoring and appropriate nutrition advice. These services were not offered diligently. Such interventions could contribute to reducing the incidence of child morbidity and mortality. PMID:26245404

    NASA's Mars Exploration Rover Opportunity captured this 360-degree panorama with its navigation camera on the rover's 354th martian day, or sol (Jan. 21, 2005). The view is presented as a cylindrical projection with geometric seam correction. Just to the right of center is the divot where Opportunity's heat shield hit the ground after protecting the spacecraft during descent through Mars'atmosphere. The heat shield was jettisoned about 90 seconds before Opportunity landed about 800 meters (half a mile) away. To the left of the divot is the flank portion of the heat shield debris and in the left foreground is the main wreckage of the heat shield. On the far right is a basketball-size rock dubbed 'Heat Shield Rock,' which Opportunity's inspection identified as an iron-nickel meteorite. The rim of 'Endurance Crater' is visible on the horizon on both the left and right ends of this full-circle view.

    Background Sleep issues such as insomnia affect over 50 million Americans and can lead to serious health problems, including depression and obesity, and can increase risk of injury. Social media platforms such as Twitter offer exciting potential for their use in studying and identifying both diseases and social phenomenon. Objective Our aim was to determine whether social media can be used as a method to conduct research focusing on sleep issues. Methods Twitter posts were collected and curated to determine whether a user exhibited signs of sleep issues based on the presence of several keywords in tweets such as insomnia, “can’t sleep”, Ambien, and others. Users whose tweets contain any of the keywords were designated as having self-identified sleep issues (sleep group). Users who did not have self-identified sleep issues (non-sleep group) were selected from tweets that did not contain pre-defined words or phrases used as a proxy for sleep issues. Results User data such as number of tweets, friends, followers, and location were collected, as well as the time and date of tweets. Additionally, the sentiment of each tweet and average sentiment of each user were determined to investigate differences between non-sleep and sleep groups. It was found that sleep group users were significantly less active on Twitter (P=.04), had fewer friends (P<.001), and fewer followers (P<.001) compared to others, after adjusting for the length of time each user's account has been active. Sleep group users were more active during typical sleeping hours than others, which may suggest they were having difficulty sleeping. Sleep group users also had significantly lower sentiment in their tweets (P<.001), indicating a possible relationship between sleep and pyschosocial issues. Conclusions We have demonstrated a novel method for studying sleep issues that allows for fast, cost-effective, and customizable data to be gathered. PMID:26054530

  13. Precision medicine: opportunities, possibilities, and challenges for patients and providers.

    Adams, Samantha A; Petersen, Carolyn

    2016-07-01

    Precision medicine approaches disease treatment and prevention by taking patients' individual variability in genes, environment, and lifestyle into account. Although the ideas underlying precision medicine are not new, opportunities for its more widespread use in practice have been enhanced by the development of large-scale databases, new methods for categorizing and representing patients, and computational tools for analyzing large datasets. New research methods may create uncertainty for both healthcare professionals and patients. In such situations, frameworks that address ethical, legal, and social challenges can be instrumental for facilitating trust between patients and providers, but must protect patients while not stifling progress or overburdening healthcare professionals. In this perspective, we outline several ethical, legal, and social issues related to the Precision Medicine Initiative's proposed changes to current institutions, values, and frameworks. This piece is not an exhaustive overview, but is intended to highlight areas meriting further study and action, so that precision medicine's goal of facilitating systematic learning and research at the point of care does not overshadow healthcare's goal of providing care to patients.

    Isoprostanoids are a group of non-enzymatic oxidized lipids from polyunsaturated fatty acids. They are commonly used as biomarkers for oxidative damage, to assess in vivo lipid peroxidation in diseases related to the vascular system and neurodegeneration. Currently, there is a mismatch with the outcome in the use of these biomarkers in intervention studies, particularly when testing the effect of antioxidants such as vitamins C and E, or zinc, or a cocktail of these, with other food components. Much of this is because the biomarkers, the method of measurement, and the duration of supplementation are unsuitable. In this review, we will highlight the formation of isoprostanoids from their respective fatty acids, and their application as biomarkers for oxidative damage in vivo, considering human dietary intervention studies evaluating plasma and urine, using mass spectrometry techniques.

    The Minority Marketing Program established baseline environmental informational data related to City of Tucson minority communities. The data is intended to be used to further develop the energy conservation, environmental education and neighborhood outreach programs. The goal of these new programs is to positively affect the participating rates of all City sponsored community environmental programs with a special emphasis on minority communities. The Minority Marketing Program developed a survey, in conjunction with the University of Arizona, to establish a database of environmental awareness information City-wide but with a special emphasis on an area composed of 10 census tracts within a primarily Hispanic community. This survey was constructed using federal non-proprietary software entitled Questionnaire Programming Language (QPL) and was administered as a computer assisted telephone interview (CATI), as well as a total design method mail-out survey. This approach produced data that is reliable within {+-} 5%. It will also establish a database against which future data can be compared.

    A traditional education in physics does not normally include business classes or dealing with opportunities to start a company, yet scientists often now start and run small companies. Physicists are mainly interested in technology. However, other factors quickly dominate chances for business success. These include finance, accounting, cash flow analysis, recruiting, interviewing, personnel issues, marketing, investments, retirement plans, patents and other not always so fun activities. Technical decisions are often strongly influenced by company finances and market-analysis. This talk discusses how to recognize opportunity, how to minimize chances for failure, and lifestyle changes one needs to be aware of before entrepreneurship involvement.

    The globalization of public health poses new threats to health but also holds important opportunities in the coming century. This commentary identifies the major threats and opportunities presented by the process of globalization and emphasizes the need for transnational public health approaches to take advantage of the positive aspects of global change and to minimize the negative ones. Transnational public health issues are areas of mutual concern for the foreign policies of all countries. These trends indicate a need for cross-national comparisons (e.g., in the areas of health financing and policy development) and for the development of a transnational research agenda in public health.

    the purpose of this meeting is to present new and current research which: shares an empirical methodology of observation and measurement; concerns interdisciplinary studies of art, archaeology, architecture, ancient technology, and conservation; and uses the knowledge, methods and tools of materials science and engineering. Druzik introduced the symposium as follows: It is not inaccurate to say that Materials Issues in Art and Archaeology II is a continuing experiment. It is an experiment in the sense that conservation scientists, materials scientists who usually deal with the properties and processing of modern technology, and those who study the materials and processing of ancient cultures seldom have an opportunity to experience each other's unique problems. While the conservation of artistic and cultural properties often involves the very same objects as those studied by students of ancient technology these two specialized species seldom, if ever, attend the same meetings, publish in the same journals, or can even name a paltry subset of the other discipline's more famous characters and controversies. And, what do the Real Material Scientists think of these two odd birds. Well, that's what we really want to find out. Because it's certainly clear to myself and my co-organizers that the MRS has undreamed of potential and wealth to help solve many of the questions we pose about past cultures, their tools, their aesthetic sensibilities and their preservation for future generations were we only imaginative enough to exploit it.

    1975-02-01

    Modern crises present decision makers with many agonizing management choices. Very often a crisis manager is confronted with a plethora of conflicting information and given very little time to choose an appropriate course of action. Although contemporary methods of systems analysis have been used in attempts to organize data and clarify options, they have generally been of little use in presenting an accurate picture of an opponent's values and perceptions. Thus it is clear that we must now make use of the improved communications and technological devices at our disposal if crises are to be avoided or resolved with minimum damage. Our proposal to establish international model-oriented computer-assisted conferences is designed to promote greater cooperation and understanding among scientists and crisis managers of differing nations by enabling them to share images of themselves and one another. With better information and more rational options available, the chances of catastrophic misunderstanding or miscalculation can be meaningfully reduced. We have proposed a possible scenario for the initial implementation of such a system to combat famine, and hope that the same approach might be used in other areas over time. The ultimate goal is a system by which specialists of all persuasions cooperate so that international crises will be resolved on the bases of mutual benefits without resort to armed conflict.

    Qualitative and quantitative issues are particularly significant in integrated regional assessment. This chapter examines the terms “qualitative” and “quantitative” separately and in relation to one another, along with a discussion of the degree of interdependence or overlap between the two. Strategies for integrating the two general approaches often produce uneasy compromises. However, integrated regional assessment provides opportunities for strong collaborations in addressing specific problems in specific places.

  2. Atlantic opportunities for ENSO prediction

    El Niño-Southern Oscillation (ENSO) is the dominant mode of tropical climate variability with worldwide impacts. Major advances in ENSO research have been done in the last decades, focusing on the mechanisms involved in its onset and development, as well as, its global climate teleconnections. Although modelling efforts have been made in ENSO forecast, the prediction of these episodes still remains a challenge for the scientific community. Recent studies put forward the role of extra-tropical and tropical regions as precursors of ENSO, but these teleconnections have changed along the 20th century. In particular, an Atlantic Niño precedes the development of a Pacific La Niña (and vice versa) 6 months in advance, taking part of an air-sea coupled mode of variability which only shows up during negative phases of the Atlantic Multidecadal Oscillation (AMO). The non-stationarity of this mode opens window opportunities for ENSO forecast, using the Tropical Atlantic Sea Surface Temperature (SST) as the predictor field. Here, we present for the first time a statistical crossvalidated hindcast of ENSO events based on an Extended Multiple Maximum Covariance Analysis (EMMCA). This method considers a unique predictor field, the summer Atlantic SSTs, and a set of predictant fields in different regions and seasons, according to the Atlantic-Pacific mechanism. The predicted tropical Pacific variables involved in ENSO development, show a good agreement with the observed ones during negative AMO phases, with a remarkable increase of the predictability skill based on correlations. During those negative AMO decades, the hindcast reproduces quite well the observed Atlantic-modulated ENSO episodes, but with stronger signal than observations. This AMO-dependency of the ENSO predictability could help to resolve some open questions about the seasonal to decadal ENSO forecast and its impacts.

    Current economic conditions make the practice of equine medicine challenging, to say the least. The downward trend in the US economy has had a huge impact on horse owners and equine veterinarians alike. Horses are expensive to keep; as such, economics are the driving factor in the problem of the unwanted horse. Under these conditions, efficient equine ambulatory practices are well-suited to weather the economic storm. As contributors to this issue of Veterinary Clinics of North America note, one can practice high-quality medicine and surgery without the overhead and expense of a large clinic. Ambulatory practitioners certainly face formidable challenges, but they also have opportunities to establish and secure a good future. PMID:22640575

  4. Sulfoximines: a neglected opportunity in medicinal chemistry.

    2013-09-01

    Innovation has frequently been described as the key to drug discovery. However, in the daily routine, medicinal chemists often tend to stick to the functional groups and structural elements they know and love. Blockbuster cancer drug Velcade (bortezomib), for example, was rejected by more than 50 companies, supposedly because of its unusual boronic acid function (as often repeated: "only a moron would put boron in a drug!"). Similarly, in the discovery process of the pan-CDK inhibitor BAY 1000394, the unconventional proposal to introduce a sulfoximine group into the lead series also led to sneers and raised eyebrows, since sulfoximines have seldom been used in medicinal chemistry. However, it was the introduction of the sulfoximine group that finally allowed the fundamental issues of the project to be overcome, culminating in the identification of the clinical sulfoximine pan-CDK inhibitor BAY 1000394. This Minireview provides an overview of a widely neglected opportunity in medicinal chemistry--the sulfoximine group. PMID:23934828

    Purpose: In this study, the algorithms and calculation setting effect and contribution weighing on prostate Volumetric Modulated Arc Therapy (VMAT) based SBRT were evaluated for clinical analysis. Methods: A low risk prostate patient under SBRT was selected for the treatment planning evaluation. The treatment target was divided into low dose prescription target volume (PTV) and high Dose PTV. Normal tissue constraints include urethra and femur head, and rectum was separated into anterior, lateral and posterior parts. By varying the constraint limit of treatment plan calculation setting and algorithms, the effect on dose coverage and normal tissue dose constraint parameter carried effective comparison for the nominal prescription and constraint. For each setting, their percentage differences to the nominal value were calculated with geometric mean and harmonic mean. Results: In the arbitrary prostate SBRT case, 14 variables were selected for this evaluation by using nominal prescription and constraint. Six VMAT planning settings were anisotropic analytic algorithm stereotactic beam with and without couch structure in grid size of 1mm and 2mm, non stereotactic beam, Acuros algorithm . Their geometry means of the variable sets for these plans were 112.3%, 111.9%, 112.09%, 111.75%, 111.28%, and 112.05%. And the corresponding harmonic means were 2.02%, 2.16%, 3.15%, 4.74%, 5.47% and 5.55%. Conclusions: In this study, the algorithm difference shows relatively larger harmonic mean between prostate SBRT VMAT plans. This study provides a methodology to find sensitive combined variables related to clinical analysis, and similar approach could be applied to the whole treatment procedure from simulation to treatment in radiotherapy for big clinical data analysis.

    Background. Pollinators, which provide the agriculturally and ecologically essential service of pollination, are under threat at a global scale. Habitat loss and homogenisation, pesticides, parasites and pathogens, invasive species, and climate change have been identified as past and current threats to pollinators. Actions to mitigate these threats, e.g., agri-environment schemes and pesticide-use moratoriums, exist, but have largely been applied post-hoc. However, future sustainability of pollinators and the service they provide requires anticipation of potential threats and opportunities before they occur, enabling timely implementation of policy and practice to prevent, rather than mitigate, further pollinator declines. Methods.Using a horizon scanning approach we identified issues that are likely to impact pollinators, either positively or negatively, over the coming three decades. Results.Our analysis highlights six high priority, and nine secondary issues. High priorities are: (1) corporate control of global agriculture, (2) novel systemic pesticides, (3) novel RNA viruses, (4) the development of new managed pollinators, (5) more frequent heatwaves and drought under climate change, and (6) the potential positive impact of reduced chemical use on pollinators in non-agricultural settings. Discussion. While current pollinator management approaches are largely driven by mitigating past impacts, we present opportunities for pre-emptive practice, legislation, and policy to sustainably manage pollinators for future generations.

    The varied career opportunities open to clinical engineers are described in this paper. Many of these opportunities are within the medical device industry in research, development, manufacturing design, regulatory activities, production, operations, sales, marketing, service, and management. Additional opportunities are available in hospitals, with the Veterans Administration, or working as an entrepreneur or a consultant. Each of these careers requires specific training and skills, and they all require a fundamental scientific knowledge of physical principles and mathematics. Research and management, however, require different educational preparation. The research emphasis should be on theoretical principles and creativity; the management emphasis should be on financial and labor problems. In all clinical engineering careers, the individual is a problem solver. PMID:10120058

    2008-05-01

    Genomics provides information on genetic susceptibility to diseases and new possibilities for interventions which can fundamentally alter the design of fair health policies. The aim of this paper is to explore implications of genomics from the perspective of equal opportunity ethics. The ideal of equal opportunity requires that individuals are held responsible for some, but not all, factors that affect their health. Informational problems, however, often make it difficult to implement the ideal of equal opportunity in the context of healthcare. In this paper, examples are considered of how new genetic information may affect the way individual responsibility for choice is assigned. It is also argued that genomics may result in relocation of the responsibility cut by providing both new information and new technology. Finally, how genomics may affect healthcare policies and the market for health insurance is discussed. PMID:18448717

    Opportunity had driven 133 meters (436 feet) that sol, crossing sand ripples up to about 10 centimeters (4 inches) tall. The tracks visible in the foreground are in the east-northeast direction.

    Opportunity's position on Sol 1687 was about 300 meters southwest of Victoria Crater. The rover was beginning a long trek toward a much larger crater, Endeavour, about 12 kilometers (7 miles) to the southeast.

    This view is presented as a cylindrical projection with geometric seam correction.

    An agent operating in an unpredictable world must be able to take advantage of opportunities but cannot afford to perform a detailed analysis of the effects of every nuance of the current situation on its goals if it is to respond in a timely manner. This paper describes a filtering mechanism that enables the effective recognition of opportunities. The mechanism is based on a characterization of the world in terms of reference features, features that are both cheap and functional and that appear to be prevalent in everyday life. Its use enables the plan execution system PARETO to recognize types of opportunities that other systems cannot. Reference features can also play a role in the detection of threats, and may be involved in the development of expertise.

Opportunities with polarized protons in the Fermilab Main Injector are discussed that encompass polarized Drell-Yan scattering of unprecedented precision and also enable measurements of transversity, helicty and other transverse momentum dependent distributions. Forthcoming measurements at COMPASS-II that aim to test fundamental predictions of non-perturbative QCD, and complementary studies at RHIC-Spin that address, among others, open puzzles such as the sharing of the nucleon spin among its constituents are also discussed.

    2015-01-01

    In recent months one of the most controversially discussed topics among regulatory agencies, the pharmaceutical industry, journal editors, and academia has been the sharing of patient-level clinical trial data. Several projects have been started such as the European Medicines Agency´s (EMA) “proactive publication of clinical trial data”, the BMJ open data campaign, or the AllTrials initiative. The executive director of the EMA, Dr. Guido Rasi, has recently announced that clinical trial data on patient level will be published from 2014 onwards (although it has since been delayed). The EMA draft policy on proactive access to clinical trial data was published at the end of June 2013 and open for public consultation until the end of September 2013. These initiatives will change the landscape of drug development and publication of medical research. They provide unprecedented opportunities for research and research synthesis, but pose new challenges for regulatory authorities, sponsors, scientific journals, and the public. Besides these general aspects, data sharing also entails intricate biostatistical questions such as problems of multiplicity. An important issue in this respect is the interpretation of multiple statistical analyses, both prospective and retrospective. Expertise in biostatistics is needed to assess the interpretation of such multiple analyses, for example, in the context of regulatory decision-making by optimizing procedural guidance and sophisticated analysis methods.

  11. Complementary and alternative medicine. Integrative medicine: business risks and opportunities.

    PubMed

    Berndtson, K

    1998-01-01

    Much of the buzz over integrative medicine is well deserved. The opportunities seem to outweigh the risks, but superior management skills are needed to guide these programs through adolescence into clinical and business maturity. By carefully considering the staffing, team building, compensation methods, marketing, and program evaluation and development issues explored in this article, health care and physician executives should be able to steer between the rocks on their way to integrative medicine decisions that are right for their organizations. Many claim that integrative medicine has the potential to reshape health care delivery in a more patient-centered direction. While this may be true, such programs must prove themselves from financial and clinical operational perspectives in order to achieve this potential. Luminary clinical skills are not enough to guarantee the survival of such programs--a strong clinical base of expertise in alternative therapies is a key success factor. As with any health care venture, there are no substitutes for clinical excellence or sound management. PMID:10351711

    Pickles, D.K.; Destribats, A.F.

    1994-07-01

    This report provides an overview of utility experience with diversification into non-traditional areas closely related to the core business. Specific examples of utility activities are discussed, and emphasis is placed on identifying {open_quotes}lessons learned{close_quotes} and other significant factors which contribute to, or detract from, the ultimate success of the activity. This report identifies numerous factors which contribute to the success of diversification activities in four general categories: (1) financial services, (2) communication services, (3) information services, and (4) products. Each category is developed with respect to: the customer need, the utility opportunity, and preliminary experience and issues. Overarching issues with respect to utility diversification generally are also discussed. Major findings include the identification of meaningful utility opportunity in several areas, along with several structural characteristics which utilities will need to address. These characteristics highlight the fact that how a utility chooses to diversify may be as important as the actual activity chosen.

  13. Active Play Opportunities at Child Care

    Saelens, Brian E.; Christakis, Dimitri A.

    2015-01-01

    BACKGROUND AND OBJECTIVES: Physical activity (PA) is important for children’s health and development, yet preschoolers are not meeting PA recommendations. The objective of this study was to examine different PA opportunities at child care and how variation in indoor versus outdoor and free versus teacher-led opportunities relate to children’s PA. METHODS: An observational study of 98 children (mean age 4.5 years, 49% girls) from 10 child care centers. Classrooms were observed for at least 4 full days per center (total 50 days) to categorize time into (1) not an active play opportunity (APO); (2) naptime; (3) APO, outdoor free play; (4) APO, outdoor teacher-led; (5) APO, indoor free play; and (6) APO, indoor teacher-led. Children wore accelerometers during observations. Linear regression models examined the influence of APO categories on moderate-vigorous physical activity (MVPA) and sedentary time. RESULTS: Children’s activity was 73% sedentary, 13% light, and 14% MVPA. For 88% of time children did not have APOs, including 26% time as naptime. On average, 48 minutes per day were APOs (41% sedentary, 18% light, and 41% MVPA), 33 minutes per day were outdoors. The most frequent APO was outdoor free play (8% of time); outdoor teacher-led time was <1%. Children were more active and less sedentary outdoors versus indoors and during the child-initiated APOs (indoors and outdoors) versus teacher-led APOs. CONCLUSIONS: Preschoolers were presented with significantly fewer than recommended opportunities for PA at child care. More APOs are needed for children to meet recommendations, particularly those that encourage more outdoor time, more teacher-led and child-initiated active play, and flexibility in naptime for preschoolers.

  14. Information superhighway: Issues affecting development

    NASA Astrophysics Data System (ADS)

    1994-09-01

    Technological advances in the transmission of voice, video, and data are fostering fundamental changes in the telecommunications industry. For example, large local telephone companies plan to offer video services in competition with cable and broadcast television, while cable television companies plan to offer local telephone service over their wires in competition with the local telephone companies. The administration believes that these technological changes provide the opportunity to develop an 'Information Superhighway' that could provide every element of society with ready access to data, voice, and video communications. Concurrently, the Congress is considering sweeping changes to telecommunications regulations to keep pace with this dynamic industry. GAO prepared this report to serve as an overview of three key issues that decisionmakers may face as they deliberate telecommunications legislation; it focuses on three pivotal issues they face in formulating new telecommunications legislation: (1) managing the transition to a more competitive local telecommunications marketplace; (2) ensuring that all consumers have access to affordable telecommunications as competition develops; and (3) ensuring that the Information Superhighway provides adequate security, privacy, reliability, and interoperability.

    2009-01-01

    NASA's Mars Exploration Rover Opportunity used its navigation camera to take the images combined into this full-circle view of the rover's surroundings during the 1,825th Martian day, or sol, of Opportunity's surface mission (March 12, 2009). North is at the top.

    This view is presented as a polar projection with geometric seam correction.

    The rover had driven half a meter (1.5 feet) earlier on Sol 1825 to fine-tune its location for placing its robotic arm onto an exposed patch of outcrop including a target area informally called 'Cook Islands.' On the preceding sol, Opportunity turned around to drive frontwards and then drove 4.5 meters (15 feet) toward this outcrop. The tracks from the SOl 1824 drive are visible near the center of this view at about the 11 o'clock position. For scale, the distance between the parallel wheel tracks is about 1 meter (about 40 inches). Opportunity had previously been driving backward as a strategy to redistribute lubrication in a wheel drawing more electrical current than usual.

    The outcrop exposure that includes 'Cook Islands' is visible just below the center of the image.

    The terrain in this portion of Mars' Meridiani Planum region includes dark-toned sand ripples and lighter-toned bedrock.

    2001-05-01

    Following the completion of a Ph.D. degree, in the sciences a postdoctoral appointment has traditionally been a key step in career development to expand the student's background and broaden their perspective. The postdoctoral appointment often is almost a requirement to obtain some positions in academia and government laboratories. In addition, postdoctoral positions in industry are becoming more common and offer an opportunity to explore a field without making a long-term commitment. We describe the nature of a postdoctoral appointment and discuss the advantages and disadvantages of the recent Ph.D. taking a postdoctoral position. We comment on the role such positions play in university, government and the corporate research. Finally, we describe some of the national postdoctoral opportunities that exist including large programs offered by the National Research Council through Federal laboratories including those of NASA, NOAA, EPA, and the Department of Defense. Exciting new interdisciplinary opportunities such as fellowships at the NASA Astrobiology Institute are summarized, as are international opportunities such as the von Humboldt fellowships in Germany.

  17. Global report on preterm birth and stillbirth (5 of 7): advocacy barriers and opportunities

    PubMed Central

    2010-01-01

    Background Efforts to achieve the Millennium Development Goals (MDGs) to improve maternal and child health can be accelerated by addressing preterm birth and stillbirth. However, most global health stakeholders are unaware of the inextricable connections of these adverse pregnancy outcomes to maternal, newborn and child health (MNCH). Improved visibility of preterm births and stillbirths will help fuel investments and strengthen commitments in the discovery, development and delivery of low-cost solutions globally. This article addresses potential barriers and opportunities to increasing global awareness and understanding. Methods Qualitative research was conducted to analyze current knowledge, attitudes and commitments toward preterm birth and stillbirth; identify advocacy challenges; and learn more about examples of programs that successfully advocate for research and appropriate interventions. Forty-one individuals from 14 countries on six continents were interviewed. They included maternal, newborn, and child health advocates and implementers, United Nations agency representatives, policymakers, researchers, and private and government donors. Results A common recognition of three advocacy challenges with regard to preterm birth and stillbirth emerged from these interviews: (1) lack of data about the magnitude and impact; (2) lack of awareness and understanding; and (3) lack of low-cost, effective and scalable interventions. Participants also identified advocacy opportunities. The first of these opportunities involves linking preterm birth and stillbirth to the MDGs, adding these outcomes to broader global health discussions and advocacy efforts, and presenting a united voice among advocates in the context of broader MNCH issues when addressing preterm birth and stillbirth. Another key opportunity is putting a human face to these tragedies—such as a parent who can speak to the personal impact on the family. Lastly, several interviewees suggested identifying and

    Opportunity arrived at exposures of Endeavour crater rim rocks in August 2011, on a hill dubbed 'Cape York.' These rocks have been the goal of exploration by Opportunity for the past few years because spectral evidence for phyllosilicates was observed at this location in orbital remote sensing data. As Opportunity circum¬navigated Cape York, the Microscopic Imager (MI) was used to examine the fine-scale textures of various soils and rocky outcrops. As reported previously, Opportunity discovered multiple bright linear features along the western periphery of Cape York that have been interpreted as veins of Ca sulfate deposited in fractures within the bedrock of Cape York. Opportunity then explored the northern and eastern sides of Cape York, including the area around 'Matijevic Hill' that shows evidence for phyllosilicates in CRISM data acquired from the Mars Reconnaissance Orbiter. One of the first outcrops examined near Matijevic Hill, dubbed 'Kirkwood,' is dominated by millimeter-size spherules. Unlike the hematite-rich concretions observed by Opportunity on Meridiani Planum, the aggregated 'newberries' in the Kirkwood exposure display internal structure and resistant rims. Compositionally, the spherule-rich rock is very similar to a nearby spherule-poor outcrop dubbed 'Whitewater Lake.' Thus these spherules have a more basalt-like composition compared to the hematite-rich concretions of the Burns Formation. The origin of the Kirkwood outcrop is uncertain, but the setting on the rim of the 22-km diameter Endeavour crater suggests that perhaps impact melting was involved in lapilli formation, possibly followed by mobilization and sorting in the ejecta blanket. Alternatively, the newberries may be diagenetic iron oxide concretions that are less well cemented than the 'blueberries' of the younger sulfate-rich Burns Formation. The Whitewater Lake outcrops contain the phyllosilicate phases observed from orbit, and are the oldest materials yet investigated by
